ITEM  1.  BUSINESS

     (a) General Development of Business.  The general development
         --------------------------------
of the registrant's business for the fiscal year ended October 31,
1993, is set out in the registrant's 1993 Annual Report to
Stockholders on pages 10 through 13 and is incorporated by reference
herein.  No material changes in the registrant's mode of doing
business occurred during the five years ended October 31, 1993.
     (b)  Financial information about Industry Segments.  Industry
          ----------------------------------------------
segment data is set out in the registrant's 1993 Annual Report to
Stockholders on pages 14-17 under the caption "1993 Operating
Results", page 18 under the caption "Industry Segment Data", page 19
under the caption "Worldwide Operations" and page 28 under the
caption "Segment Information", and is incorporated by reference
herein.
     (c)  Narrative Description of Business.
          ----------------------------------
            1)  Specialty Chemical Segment.  Specialty chemicals are
                ---------------------------
produced primarily from petrochemicals and petroleum derived raw
materials, and include demulsifiers, corrosion inhibitors, drilling
fluids, polymers and waxes, water treating chemicals, and fuel and
other additives.  Sales for the three major product groupings within
the specialty chemical segment (oil field chemicals, industrial
chemicals, and industrial polymers and waxes) for each of the three
years in the period ended October 31, 1993, are provided in the 1993
Annual Report to Stockholders on page 18 under the caption "Industry
Segment Data" which is incorporated by reference herein.
            Registrant markets its products and services primarily
to producers and transporters of crude oil and natural gas, related
service companies and petroleum refineries throughout the world
through the registrant's own field staff and a limited number of
agents and distributors.  The registrant also serves other major
markets, such as adhesives, agribusiness, coatings, packaging,
petrochemicals, plastics fabrication, power utilities, and printing
inks.

                                    -3-
<PAGE> 4
     During the fiscal year ended October 31, 1993, there have been
no significant changes in the kinds of products or services
rendered, or in the markets or methods of distribution by
registrant.  It is the continuing nature of the business for a
number of new or improved products to be introduced annually;
typically, no individual new product or service by itself is
expected to be significant immediately in sales or earnings.
     Registrant's joint business alliance with Energy BioSystems
Corporation continues to make steady progress in its efforts to
commercialize a breakthrough biocatalytic desulfurization (BDS)
process for hydrocarbons.  Registrant's participation has expanded
to worldwide coverage at 22% of gross profits from
biodesulfurization unit sales and fees.  In return, registrant will
provide development resources, separation technology, engineering
know-how and ongoing customer service for all BDS units, worldwide.
     Registrant is dependent on the availability of petrochemicals
and petroleum-derived raw materials and supplies, which have been
available in the past in adequate quantities.  In the past year,
registrant's operations were not affected materially by any raw
material shortages.  Registrant presently does not foresee any
shortage of materials in the near future.
     Registrant has numerous patents, patent applications, and
licenses under patents, of various durations which, in the
aggregate, are material to the operation of the registrant.  The
registrant, however, does not believe that expiration of any
particular patent or group thereof would have a material adverse
effect upon its business as a whole.
     The specialty chemical business is not considered to be
seasonal.
     The registrant traditionally has carried sufficient inventory
at various stages of production in order to respond quickly to the
needs of its customers.  Accounts receivable generally are due
within thirty days of invoicing, and letters of credit are employed
when deemed appropriate.  The registrant believes that its practices
are consistent with industry standards.
     Registrant's customers are located throughout the world and no
one customer

                                    -4-
<PAGE> 5
constitutes more than 10% of the registrant's business.
     Foreign operations account for a significant portion of the
registrant's specialty chemical business.  Non-U.S. revenues were
approximately 32% of total specialty chemical revenues during each
of the last three years.
     Orders from customers for specialty chemical products
generally are filled from stock or manufactured within a few days or
weeks after receipt of the order and, as a result, backlog of orders
is not significant in relation to total annual dollar volume of
sales.
     The registrant's specialty chemical product lines, oil field
chemicals, industrial chemicals, and industrial polymers and waxes
are in competition with a number of manufacturers.  Competitive
companies vary in size from large international companies to small
companies which may compete with the registrant in the sale of one
product or a line of products.  All aspects of this business are
considered to be very competitive.  Registrant is recognized as a
leader in providing services and products to the oil field chemical
market.  In the registrant's opinion, registrant's overall
competitive position in the market has not changed materially in the
past fiscal year, although registrant is unable to predict the
extent to which its business may be affected by future competition
or by consolidations within the industry.  Information on
acquisitions made by the registrant in fiscal 1993 is set out in the
registrant's 1993 annual report on page 25 under the caption
"Acquisitions" and is incorporated by reference herein.
     2.  Equipment Segment - The equipment segment designs,
         -----------------
installs and services processing equipment for petroleum,
petrochemical and electrical power generating industries.  Products
and services are marketed both domestically and in foreign countries
through the registrant's own field staff and a limited number of
agents and distributors.
     During the past year the registrant has not had, and in the
foreseeable future does not anticipate, any shortage of raw
materials.
     Certain products of the equipment segment are covered under
patents, patent

                                    -5-
<PAGE> 6
applications, and licenses under patents. Registrant does not believe that
expiration of any particular patent or group thereof would have a material
adverse effect upon its business as a whole.
     The equipment segment business is not seasonal, but is subject
to the business cycles of the industries which it serves.
     This segment primarily produces processing equipment upon
order from customers.  Accounts receivable generally are due within
thirty days of invoicing, and letters of credit are employed when
deemed appropriate.  The registrant believes that its practices are
consistent with industry standards.
     Registrant's customers are located throughout the world and no
one customer constitutes a significant portion of the registrant's
business on a continuing basis.  However, one or several equipment
contracts may represent a significant portion of the equipment
segment revenues in a particular year.
     Foreign operations account for a significant portion of the
registrant's equipment business.  Non-U.S. revenues ranged from 40%
to 67% of total equipment revenues during the last three years.
     The amount of backlog orders for the equipment segment at
October 31, 1993, approximates $11.5 million.  Substantially all of
these orders are expected to be completed in fiscal 1994.  Backlog
orders as of October 31, 1992 were $8.7 million.
     The equipment segment is in competition with similar equipment
and services offered by other competitors. Although, in registrant's
opinion, registrant's competitive position in its equipment business
has not changed materially in the past year, the registrant is
unable to predict the extent to which its business may be affected
by future competition.

     3. Registrant's Business in General - The registrant expended
        --------------------------------
$13,587,000, $12,224,000, and $11,431,000, in fiscal years 1993,
1992 and 1991, respectively, on

                                    -6-
<PAGE> 7
research activities relating to development of new products and services,
and on improvement of existing products and services.  Approximately 95%
was applicable to the registrant's specialty chemical products segment.  The
registrant also continued its strong commitment to technology by
continuing to increase its emphasis on field applications support
which, when combined with the research and development amounts,
resulted in total technology expenditures of $24,444,000,
$21,764,000, and $20,474,000 in fiscal years 1993, 1992 and 1991,
respectively.  The registrant directly sponsors substantially all of
its research activities.
     The registrant is subject to various federal, state and local
laws and regulations concerning environmental matters.  The
registrant maintains a separate Safety, Health and Environmental
Affairs Department charged with the responsibility of monitoring
compliance with these various laws and regulations.  For fiscal year
1993, these efforts did not result in any material capital
expenditure or material charges to income, and it is not likely that
these efforts will result in any material capital expenditure or
material charges to income during fiscal year 1994.
     Approximately 2,012 persons are employed worldwide by
registrant and its subsidiaries.
     (d) Financial Information About Foreign and Domestic
         ------------------------------------------------
Operations and Export Sales.  Information under this caption is
- ----------------------------
included in the registrant's 1993 Annual Report to Stockholders for
each of the three years ended October 31, 1993, 1992, and 1991,
respectively, on page 19 under the caption "Worldwide Operations"
and is incorporated by reference herein.
     Substantially all of the registrant's non-U.S. sales are made
to major international companies, national oil companies and
utilities, and contractors and distributors of long standing.
Letters of credit are required when and where appropriate.  The risk
attendant to the foreign business conducted by registrant and its
subsidiaries is believed to be slightly greater than the risk
involved in doing business within the United States.  The

                                    -7-
<PAGE> 8
registrant protects itself from potential losses due to foreign currency
fluctuations through pricing adjustments, maintenance of offsetting
asset and liability balances, and utilization of foreign currency
futures contracts when deemed appropriate.

       In addition to the foregoing properties, the registrant and its
subsidiaries occupy a number of small general and sales offices under short-
term leases and its subsidiaries occupy a number of distribution warehouses
located on small sites owned in fee.
       Although facilities are of varying ages, the registrant considers them
generally to be well maintained, equipped with modern and efficient
equipment, and in good operating condition.  Current productive capacity is
adequate to meet demands for the immediate future.

ITEM 3. LEGAL PROCEEDINGS

       Neither the registrant nor any of its subsidiaries is a party to, nor
is any of their property subject to, any material pending legal proceedings,
other than routine litigation incidental to the business.
       The registrant is subject to various laws and governmental regulations
concerning employee safety and environmental matters.  The registrant
maintains a separate Safety,  Health and Environmental Affairs Department
charged with the responsibility of monitoring compliance with these various
laws and regulations.  The registrant currently participates, as a
potentially responsible party and otherwise, with various governmental
agencies concerning certain environmental cleanup sites.  After consultation
with environmental and engineering advisors, and legal counsel, the
registrant does not believe that the registrant's participation at these
sites, individually and collectively, is likely to result in the payment of
any material sanctions, capital expenditures or charges to income.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

       There were no matters submitted to a vote of security holders, through
the

                                    -9-

solicitation of proxies or otherwise, during the fourth quarter of fiscal 1993.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED
     STOCKHOLDER MATTERS

       Information regarding registrant's common stock appears on page 17 of
the registrant's 1993 Annual Report to Stockholders under the caption
"Stockholders' Equity/Capital Stock" and is incorporated by reference herein.
As of January 7, 1994 the registrant has 2,093 stockholders of record.

ITEM 6. SELECTED FINANCIAL DATA

       A summary of selected financial data for the five years ended 10/31/93
appears on pages 30 and 31 of the registrant's 1993 Annual Report to
Stockholders under the caption "11-Year Summary", and is incorporated by
reference herein.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
    RESULTS OF OPERATIONS

       Information under this caption is in the registrant's 1993 Annual
Report to Stockholders on pages 14 through 19, under the caption "Financial
Review", and on pages 25 and 26 under the captions "Acquisitions, Short-Term
Borrowings and Lines of Credit, and Long-Term Debt" and is incorporated by
reference herein.
       The registrant continued its program to cease manufacturing operations
at its Webster Groves, Missouri facility to coincide with an expansion of its
La Porte, Texas facility.  As and when such operations cease, the registrant
expects that appropriate reserves will be established.  This program will
increase manufacturing capacity, efficiency and flexibility, and ultimately
will allow for any necessary additions to sales, administrative and research
facilities at Webster Groves.
       On January 27, 1993, the registrant announced that it adopted Statement
of Financial Accounting Standard No. 106 related to medical and other
postretirement benefits.  The adoption of this rule resulted in a one-time,
non-cash charge of $6.5 million, or $0.58 per share, to net income in fiscal
1993's first quarter ending January 31.

                                    -10-
<PAGE> 11
       During the first quarter of fiscal 1994, the registrant will adopt
Statement of Financial Accounting Standard No. 109, "Accounting for Income
Taxes."   Statement 109 will change the company's method of accounting for
income taxes from the deferred method (APB 11) to an asset and liability
approach.  The estimated cumulative effect of implementing the new standard,
using current tax rates, will be a one-time, non-cash credit of $2.0 million,
or $0.18 per share, to net income in fiscal 1994's first quarter ending
January 31.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

       Consolidated Financial Statements of the registrant and its
subsidiaries, and the Notes to Consolidated Financial Statements, together
with the report thereon of Price Waterhouse dated November 30, 1993,
appearing on pages 20 through 29, the Quarterly Results on pages 15 and 16,
Industry Segment Information on page 18, and Worldwide Operations Information
on page 19 in the registrant's 1993 Annual Report to Stockholders, are
incorporated by reference in this Form 10-K Annual Report.
       Marketable securities are stated at their approximate market value at
October 31, 1993.  The registrant's provision for bad debts was $395,000,
$338,000, and $281,000, for fiscal years 1993, 1992, and 1991, respectively.

ITEM 9.  DISAGREEMENTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

       During the registrants three most recent fiscal years, there were no
changes in or disagreements with the registrants independent accountants on
accounting or financial disclosure.

Major capital expenditures in fiscal 1993, 1992, and 1991 included property,
plant and equipment from the Welchem acquisition, a new information system
principally to serve the Tretolite and Industrial Chemicals Divisions,
continuing expansion and upgrading of the Bayport Chemical manufacturing
plant, investments in bulk containers and related distribution facilities,
and a new EuroChem Division office building in Kirkby, England.

Depreciation is generally provided on  a straight-line basis at rates based
on estimated useful lives of
properties.

and transact such other business as may properly be brought before the meeting.

     Section 3.  A majority of the stock issued and outstanding and entitled
to vote at any meeting of stockholders, the holders of which are present in
person or represented by proxy, shall constitute a quorum for the transaction
of business except as otherwise provided by law, by the Certificate of
Incorporation, or by these By-Laws.  If, however, such quorum shall not be
present or represented at any meeting of the stockholders, a majority of the
voting stock represented in person or by proxy may adjourn the meeting from
time to time, without notice other than announcement at the meeting, until a
quorum shall be present or represented.  At such adjourned meeting at which
a quorum shall be present or represented, any business may be transacted
which might have been transacted at the meeting as originally noticed.  If
the adjournment is for more than thirty (30) days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled
to vote thereat.

present in person or represented by proxy shall decide any question brought
before such meeting, unless the question is one upon which by express provision
of the statutes, or the Certificate of Incorporation, or these By-Laws, a
different vote is required in which case such express provision shall govern
and control the decision of such question.

     Section 5.  At each meeting of the stockholders, each stockholder
having the right to vote may vote in person or may authorize another person
or persons to act for him by proxy appointed by an instrument in writing
subscribed by such stockholder and bearing a date not more than three (3)
years prior to said meeting, unless said instrument provides for a longer
period.  All proxies must be filed with the Secretary of the Corporation at
the beginning of each meeting in order to be counted in any vote at the
meeting.  A proxy shall be deemed signed if the stockholder's name is placed
on the proxy (whether by manual signature, typewriting, telegraphic

in fact.  Each stockholder shall have one vote for each share of stock having
voting power, registered in his name on the books of the Corporation on the
record date set by the Board of Directors as provided in Article V, Section 6
hereof.  All elections shall be had and all questions decided by a plurality
vote.

Board of Directors which has been duly designated by the Board of Directors
and whose power and authority, as provided in a resolution of the Board of
Directors or in the By-Laws, includes the power to call such meetings.
Special meetings of stockholders of the Corporation may not be called by any

stockholders shall be limited to the purposes stated in the notice.

     Section 7.  Notice of any meeting of stockholders shall be given either
personally or by first-class mail or telegraphic or other written
communications, charges prepaid, addressed to the stockholder at the address
of such stockholder appearing on the books of the Corporation or given by the
stockholder to the Corporation for the purpose of notice.  If no such address
appears on the Corporation's books or has been so given, notice shall be
deemed to have been given if sent by first-class mail or telegraphic or other
written communication to the Corporation's principal executive office, or if
published at least once in a newspaper of general circulation in the county
where such office is located.  Notice shall be deemed to have been given at
the time

                                    -4-
<PAGE> 5
when delivered personally or deposited in the mail or sent by
telegram or other means of written communication.
     If any notice addressed to a stockholder at the address of such
stockholder appearing on the books of the Corporation is returned to the
Corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the
stockholder at such address, all future notices shall be deemed to have been
duly given without further mailing if the same shall be available to the
stockholder upon written demand of the stockholder at the principal executive
office of the Corporation for a period of one (1) year from the date of the
giving of such notice.

     Section 8.  Attendance of a person at a meeting shall constitute a
waiver of notice to such person of such meeting, except when the person
objects at the beginning of the meeting to the transaction of any business
because the meeting is not lawfully called or convened, or objects to the
consideration of matters not included in the notice of the meeting.

     Section 9.  The officer who has charge of the stock ledger of the
Corporation shall prepare and make, at least ten (10) days before every
meeting of stockholders, a complete list of the stockholders entitled to vote

each stockholder and

                                    -5-

Such list shall be open to the examination of any stockholder,
for any purpose germane to the meeting, during ordinary business hours, for
a period of at least ten (10) days prior to the meeting, either at a place
within the city where the meeting is to be held, which place shall be
specified in the notice of the meeting, or, if not so specified, at the place
where the meeting is to be held.  The list shall also be produced and kept at
the time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present.

     Section 10.  Action may be taken by stockholders either at an annual or
special meeting of stockholders, or stockholders may act by written consent.

     Section 11.  Before any meeting of stockholders, the Board of Directors
may appoint any persons other than nominees for office to act as inspectors
of election at the meeting or its adjournment.  If no inspectors of election
are so appointed, the chairman of the meeting may appoint inspectors of
election at the meeting.  The number of inspectors shall be either one (1) or
two (2).  If any person appointed as inspector fails to appear or fails or
refuses to act, the chairman of the meeting may appoint a person to fill such
vacancy.
     The duties of these inspectors shall be as follows:

                                    -6-
<PAGE> 7
          (a)  Determine the number of shares outstanding and the voting
     power of each, the shares represented at the meeting, the existence of
     a quorum, and the authenticity, validity and effect of proxies;
          (b)  Receive votes or ballots;
          (c)  Hear and determine all challenges and questions in any way
     arising in connection with the right to vote;
          (d)  Count and tabulate all votes;
          (e)  Determine the result; and
          (f)  Do any other acts that may be proper to conduct the
     election or vote with fairness to all stockholders.

                           ---------

     Section 1.  The business and property of this Corporation shall be
managed and controlled by its Board of Directors, ten (10) in number.  Unless
the Board of Directors shall otherwise determine, no Director shall stand for
re-election after he has attained the age of seventy-two (72) years.
Directors need not be stockholders.

     Section 2.  The Board of Directors, by majority vote of its members,
may at any time and from time to time, appoint one or more Advisory Directors
who shall advise and counsel the Board of Directors.  Advisory Directors may
attend meetings of said Board

                                    -7-
<PAGE> 8
but without the right to vote on any matter that may come before the Board
for consideration.  Advisory Directors shall hold office at the pleasure of
the Board of Directors; provided, however, that the term of office of any
Advisory Director shall expire in any event at the Annual Stockholders'
Meeting next following his appointment as an Advisory Director.  No Advisory
Director shall be appointed or reappointed after he has attained the age of
seventy-five (75) years; except that any current Advisory Director may be
reappointed until he has attained the age of eighty (80) years.

     Section 3.  The Directors shall be elected at the Annual Meeting of the

resignation, retirement, disqualification, removal from office, or otherwise,
and newly created directorships resulting from any increase in the authorized
number of directors may be filled by a majority of the directors then in
office, although less than a quorum, or by a sole remaining director.  The
directors so chosen shall hold office until the next annual election of
directors and until their successors are duly elected and shall qualify,
unless sooner displaced.  If there are no directors in office, then an
election of directors may be held in the manner

                                    -8-
<PAGE> 9
provided by statute.

     Section 5.  The property and business of the Corporation shall be

the powers and authorities by these By-Laws expressly conferred upon them,

Incorporation or by these By-Laws directed or required to be exercised or

consists of only one director, in which case special meetings shall be called
by the Chairman of the Board, the President or Secretary in like manner or on
like notice on the written request of the sole director.

     Section 9.  At all meetings of the Board of Directors a majority of the
authorized number of directors shall be necessary and sufficient to
constitute a quorum for the transaction of business, and the vote of a
majority of the directors present at any meeting at which there is a quorum,
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute, by the Certificate of Incorporation or by
these By-Laws.  If a quorum shall not be present at any meeting of the Board
of Directors, the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a
quorum shall be present.  If only one director is authorized, such sole
director shall constitute a quorum.  A  meeting at which a quorum is
initially present may continue to transact business notwithstanding the
withdrawal of directors, if any action is approved by at least a majority of
the required quorum for such meeting.

     Section 10.  Unless otherwise restricted by the Certificate of
Incorporation or these By-Laws, any action required or permitted to be taken

     Section 11.  Unless otherwise restricted by the Certificate of
Incorporation or these By-Laws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting
of the Board of Directors, or any committee, by means of conference telephone

a meeting shall constitute presence in person at such meeting.

                    COMMITTEES OF DIRECTORS
                    -----------------------

     Section 12.  The Board of Directors may at any time and from time to
time, create from its membership such committees as the Board may desire.
Any such committee, to the extent provided in the resolution of the Board of
Directors, shall have and may exercise such powers and authority of the Board
of Directors in the management of the business and affairs of the
Corporation, as the

                                    -11-
<PAGE> 12
Board of Directors at any time and from time to time may delegate.

their expenses, if any, of attendance at each meeting of the Board of
Directors or any committee thereof and may be paid a fixed sum for attendance
at each meeting of the Board of Directors or any Committee thereof, and a
stated salary as director.  No such payment shall preclude any director from
serving the Corporation in any other capacity and receiving compensation
therefor.

                        INDEMNIFICATION
                        ---------------

     Section 14.  (a)  The Corporation shall indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the Corporation)
by reason of the fact that he is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and

                                    -12-
<PAGE> 13
amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.  The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in
a manner which he reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.
     (b)  The Corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the Corporation to procure a judgment in
its favor by reason of the fact that he is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of
the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him
in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best

                                    -13-
<PAGE> 14
interests of the Corporation and except that no such
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable for negligence or
misconduct in the performance of his duty to the Corporation unless and only
to the extent that the Court of Chancery of Delaware or the court in which
such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to indemnity for such
expenses which such Court of Chancery or such other court shall deem proper.
     (c)  To the extent that a director, officer, employee or agent of the
Corporation shall be successful on the merits or otherwise in defense, of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in
defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection therewith.
     (d)  Any indemnification under paragraphs (a) and (b) (unless ordered
by a court) shall be made by the Corporation only as authorized in the
specific case upon a determination that indemnification of the director,
officer, employee or agent is proper in the circumstances because he has met
the applicable standard of conduct set forth in paragraphs (a) and (b).  Such
determination shall be made (1)  by the Board of Directors by a

                                    -14-
<PAGE> 15
majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding, or (2)  if such a quorum is not obtainable, or,
even if obtainable a quorum of disinterested directors so directs, by
independent legal counsel in a written opinion, or (3)  by the stockholders.
     (e)  Expenses incurred in defending a civil or criminal action, suit
or proceeding may be paid by the Corporation in advance of the final
disposition of such action, suit or proceeding as authorized by the Board of
Directors in the manner provided in paragraph (d) upon receipt of an
undertaking by or on behalf of the director, officer, employee or agent to
repay such amount unless it shall ultimately be determined that he is
entitled to be indemnified by the Corporation as authorized in this
Section 14.
     (f)  The indemnification provided by this Section 14 shall not be
deemed exclusive of any other rights to which those indemnified may be
entitled under any statute, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, and shall continue as
to a person who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of the heirs, executors and administrators of such
a person.
     (g)  The Board of Directors may authorize, by a vote of a majority of
a quorum of the Board of Directors, the Corporation to purchase and maintain
insurance on behalf of any person who is or

                                    -15-
<PAGE> 16
was a director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against him and incurred by him in
any such capacity, or arising out of his status as such, whether or not the
Corporation would have the power to indemnify him against such liability under
the provisions of this Section 14.
     (h)  For the purposes of this Section 14, references to "the
corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed
in a consolidation or merger which, if its separate existence had continued,
would have had power and authority to indemnify its directors, officers, and
employees or agents, so that any person who is or was a director, officer,
employee or agent of such constituent corporation, or is or was serving at
the request of such constituent corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, shall stand in the same position under the provisions of this
Section with respect to the resulting or surviving corporation as he would
have with respect to such constituent corporation if its separate existence
had continued.

upon whom such power of removal may be conferred by the Board of Directors.

against any claim that may be made against the Corporation with respect to
the certificate alleged to have been lost, stolen or destroyed.

principal amount thereof, payable semi-annually on the 1st day of May and
November of each year, commencing on May 1, 1994, at the rate specified
above for such notes until said principal shall have become due and

principal amounts thereof. Any partial prepayment of the Notes pursuant to
this Section 3.3 shall be applied to the required payments of principal
of the Notes of such respective series (excluding required prepayments
thereof pursuant to Section 3.1 or 3.2 and payment of the principal balance
thereof on final maturity) in the inverse order of maturity.

     3.4.  Notice of Optional Prepayments.  The Borrower shall call Notes

           (a)  Upon the occurrence of a Change of Control (the "Change of
Control Date"), each holder of any Notes shall have the right to require
the Borrower to repurchase such holder's Notes in whole or in part pursuant
to the offer described in paragraph (b) and (d) below (the "Change of
Control Offer") at a purchase price in cash equal to the principal amount

           (b)  Not less than 30 nor more than 60 days prior to any Change
of Control Date, the Borrower shall give written notice (the "Change of
Control Notice") to each holder of any Notes stating:

              (i)  that a Change of Control is expected to occur (describing
     such Change of Control in reasonable detail and identifying the parties
     thereto), that a Change of Control Offer is being made pursuant to
     this Section 3.5, and that all Notes timely tendered within 20 Business
     Days of the date of the Change of Control Notice will be accepted for
     payment;

             (ii)  the purchase date, which shall be the Change of Control
     Date (the "Change of Control Payment Date");

            (iii)  that any Note not timely tendered within the time
     specified in clause (i) above, will continue to accrue interest;

             (iv)  that any Note accepted for payment pursuant to the Change
     of Control Offer will cease to accrue interest after the Change of
     Control Payment Date;

              (v)  that holders of Notes electing to have one or more Notes
     repurchased pursuant to a Change of Control Offer will be required to
     surrender the Notes to be so repurchased within 20 Business Days of

     Borrower or in blank, to the Borrower at its address specified in
     Section 15.6 hereof prior to the close of business on the 20th
     Business Day following the date of the Change of Control Notice;

             (vi)  that any holder of Notes will be entitled to withdraw
     such holder's election with respect to any or all of the principal
     amount of Notes delivered for repurchase if the Borrower receives, not

(i) accept for payment all Notes tendered pursuant to the Change of
Control Offer and not validly withdrawn, and (ii) pay to each holder of
Notes so tendered, in immediately available funds, by wire transfer or
such other means as may be specified by such holder in writing, the

such holder. Concurrently with such payment, the Borrower shall furnish to
each holder of Notes so tendered a certificate signed by an authorized
financial officer the Borrower setting forth computations in reasonable

in part its election to have one or more of its Notes repurchased then
(A) if such election is withdrawn in whole, the Borrower shall promptly

such holder the Notes previously tendered for repurchase as contemplated
by the Change of Control Offer and (B) if such election is withdrawn in
part then the Borrower shall repurchase pursuant to this Section 3.5 only
so much of the principal amount of such Notes as shall be specified in such
notice, and on the Change of Control Payment Date shall issue to such
holder new Notes, in such denominations (multiples of $1,000) as may be
specified by such holder, in an aggregate principal amount equal to the
aggregate portion of the principal amount of the Notes so tendered by such

Borrower hereunder. All Notes repurchased pursuant to this Section 3.5
shall be cancelled and shall not be reissued. The Borrower shall give notice
to each holder of Notes of the results of the Change of Control Offer on

           (d)  Notwithstanding the foregoing, if the Borrower (i) shall
not have obtained knowledge at least 30 days prior to a Change of Control
that such Change of Control will or may occur, or (ii) shall not have
obtained knowledge until after a Change of Control has occurred, then the
Borrower shall give the notice required by Section 3.5(b) not later than
two business Days after

                                    -5-
<PAGE> 11
obtaining such knowledge. In such event, each holder of Notes may deliver
a notice of election to accept the Change of Control Offer and may tender
any or all of its Notes pursuant thereto at any time within 20 Business
Days after receiving such notice (whether or not at such time the Change
of Control Date shall have occurred). With respect to any such notice of
election and tender of Notes received by the Borrower on or prior to the
third Business Day prior to the Change of Control Date, the Borrower
shall comply with the provisions of Section 3.5(c) and make payment of the
Change of Control Purchase Price on the Change of Control Date as provided
therein. With respect to any such notice of election and tender of Notes
received by the Borrower within such 20-Business-Day period but after the
close of business on the third Business Day prior to the change of
Control Date (whether or not at such time the Change of Control Date
shall have occurred), the Borrower shall comply with the provisions of
Section 3.5(c) and make payment of the Change of Control Purchase Price
promptly, but in any event not later than five (5) days, after receipt thereof.

           (e)  Notwithstanding the foregoing, (i) in the event the
Borrower caused a notice to be delivered pursuant to Section 3.5(b) hereof,
and (ii) at any time prior to the Change of Control Payment Date, the
Borrower reasonably determines that the circumstances which were to give
rise to a Change of Control have changed so that a Change of Control in
connection with or related to such circumstances will not occur, then the
Borrower shall immediately cause written notice to be mailed, by registered
mail, return receipt requested, to each holder of Notes which notice shall
(1) state that a Change of Control will not occur, (2) describe in
reasonable detail the change of circumstances which lead to the determination
that a Change of Control will not occur, and (3) state that the Borrower's
previous notice delivered pursuant to Section 3.5(b) hereof offering to
redeem all of the Notes shall be of no further force and effect. Concurrently
with the delivery of such written notice, the Borrower shall return to
each holder of Notes any of such holder's Notes tendered pursuant to the
Change of Control Offer.

     3.6.  Cancellation of Notes; Notation Thereon.  Subject to the
           ---------------------------------------

nongovernmental Person, including without limitation any creditor or
shareholder of the Borrower, is required in connection with the execution,
delivery and performance of this Agreement, the Other Agreements or the
Notes or the transactions contemplated hereby or thereby or as a condition
to the legality, validity or enforceability of this Agreement, the Other
Agreements or the Notes, or to the offer, issue, sale or delivery of the
Notes to the Purchasers hereunder or under the Other Agreements or the
fulfillment of or compliance with the terms and provisions of the Notes
being purchased hereunder or thereunder, except for such consents,
approvals, authorizations, declarations, registrations or filings which
have been obtained or made and are in full force and effect.

     4.10.  Title to Properties.  The Disclosure Document sets forth a true
            -------------------
and complete list and brief description of all material real Property owned
by the Borrower or any of its Subsidiaries on the date hereof, except for
properties subsequently acquired from Welchem, Inc. There are no material
leases of real Property or personalty to which the Borrower or any of its
Subsidiaries is a party. Each of the Borrower and its Subsidiaries has

except Permitted Liens, and (ii) good title to all of their other
respective material Properties and material assets, subject to no Lien of
any kind except Permitted Liens.

     4.11.  Taxes.  Each of the Borrower and its Subsidiaries has filed, or
            -----
on behalf of each of them there have been filed, all federal, state and
local tax returns, informational returns and excise tax returns which are
required to have been filed by or on behalf of such Persons, and there have
been paid all taxes shown to be due and payable on such returns and all
other material taxes and assessments payable by any of them, unless any tax
liability is being diligently contested in good faith and the Borrower or
any of its Subsidiaries, as the case may be, has adequately reserved
against such tax liability on its books and financial statements in
accordance with GAAP. No material tax liens have been filed and no material
claims are being asserted with respect to any such taxes as of the date
hereof. No material tax assessment against the Borrower or any of its
Subsidiaries has been proposed and all of their respective tax liabilities
are adequately provided for on their respective books and financial
statements in accordance with GAAP. The federal income tax returns of the
Borrower and its Subsidiaries have been audited by the Internal Revenue
Service, and such audits have been completed, or the statute of limitations
has run, for all tax years of the Borrower through and including the year
ended October 31, 1989, and all deficiencies, assessments, interest and
penalties proposed as a result of any such audit have been paid in full.
No issue has been raised in any such examination that, by application of
similar principles, may reasonably be expected to result in the assertion
of a material deficiency for any other taxable year not so examined. None
of the Borrower or any of its Subsidiaries has taken any reporting position
for which it does not have a reasonable basis or anticipates any further
material tax liability with respect to its taxable years that have not been
closed.

     4.12.  No Conflicts with Agreements, Etc.  Neither the Borrower nor any
            ---------------------------------
Subsidiary is, or after giving effect to the transactions contemplated by
this Agreement and the Other Agreements will be, a party to any contract or
agreement or subject to any restriction contained in its charter or by-laws
which has a Material Adverse Effect. Neither the execution and delivery of
this Agreement, the Other Agreements or the Notes nor the fulfillment of or
compliance with the terms and provisions hereof and thereof, nor the offering
and issuance of the Notes, will conflict with, or result in a breach of the
terms, conditions or provisions of, or constitute a default under, or result
in the creation of any Lien on any Properties of the

                                    -11-
<PAGE> 17
Borrower or its Subsidiaries, or result in any violation of, or require

the Borrower pursuant to, the charter or by-laws of any of them, or any award
of any arbitrator or any contract, agreement, mortgage, indenture, lease,
instrument, Order, statute, law, rule or regulation to which any of them or
any of their respective Property is subject. Neither the Borrower nor any of
its Subsidiaries is, or after giving effect to the transactions
contemplated by this Agreement and the Other Agreements will be, in

delivered to the Purchasers or their designee), contained, as of its
respective date, or now contains, any untrue statement of a material fact or

now has or in the future may have (so far as the Borrower can reasonably
foresee) a Material Adverse Effect.

from, or otherwise approached or negotiated with respect thereto with, more
than 50 Persons including you, and neither the Borrower nor its Affiliates
nor any of their representatives has taken or will take any action which
would subject the issuance or sale of any of the Notes to the provisions
of Section 5 of the Securities Act or which would violate the provisions of
any other securities or Blue Sky law of any jurisdiction.

<PAGE> 20
are necessary for the ownership, maintenance and operation of their respective
properties and assets, and for the conduct of their respective businesses as

contesting the right of any of them to sell or use any such product or to
engage in any such operation that has or is likely to have a Material Adverse
Effect.

     4.19.  Margin Regulations; Use of Proceeds.  None of the Borrower or any
            -----------------------------------
of its Subsidiaries owns or now intends to acquire any "margin stock" as
defined in Regulation G of the Board of Governors of the Federal Reserve
System of the United States (12 CFR 207). No part of the proceeds from the
sale of the Notes will be used, and no part of the proceeds of any loans repaid

Borrower or any Subsidiary in a violation of Regulation X of said Board
(12 CFR 224) or to involve any broker or dealer in a violation of Regulation T
of said Board (12 CFR 220). Neither the Borrower, any of its Subsidiaries or
any agent acting on behalf of the Borrower or any such Subsidiary has taken
or will take any action which might cause this Agreement or the Notes to

<PAGE> 21
violate Regulation G, Regulation X, Regulation T or any other
regulation of the Board of Governors of the Federal Reserve System or
to violate the Exchange Act, in each case as in effect now or as the
same may hereafter be in effect. As used in this Section, the term
"purpose of buying or carrying" has the meaning assigned thereto in the
aforesaid Regulation G. The proceeds (net of expenses of the transactions
contemplated hereby and by the Other Agreements) of the sale of the Notes
will be used to retire Debt incurred in connection with the acquisition of
certain assets of Welchem, Inc. and for general corporate purposes of the
Borrower and its Subsidiaries.

the most recent actuarial report pertaining to each Plan;

           (g)  neither the Borrower nor any of its Subsidiaries has

in clause (iv) above and such excess principal amount of the Uncommitted
Notes shall be allocated for purchase among the other Purchasers electing

     expiration of any such stay, or which is being diligently contested
     in good faith so long as a reserve or other appropriate provision,
     if any, as shall be required by GAAP shall have been made therefor;

           (E)  zoning restrictions, easements, licenses, reservations,

     arise by, through or under or are asserted by a landlord or owner
     of the leased property, with or without consent of the lessee) which
     were not incurred in connection with the borrowing of money and which
     do not in the aggregate materially detract from the value of the
     Property of the Borrower or any of its Subsidiaries, as the case
     may be, or impair the use of such

                                    -32-

     construction or improvement of such Property or within 180 days
     thereafter, to secure Debt assumed or incurred to finance all or any
     part of the purchase price or cost of acquisition or construction or
     improvement of such Property, but any such Lien shall cover only the
     Property so acquired or constructed and any improvements thereto
     (and any real Property on which such Property is located, if such
     Property is a building, improvement or fixture), and may not exceed
     (i) the purchase price of such acquisition or the cost of such
     construction or improvement, or (ii) the Fair Market Value of the
     Property acquired, constructed or improved;

           (I)  any Lien (i) on Property existing at the time of

make or cause to be made provision whereby the Notes will be secured
equally and ratably with all other obligations secured thereby, and in any
event the holders of the Notes shall have the benefit, to the full extent
that, and

                                    -33-
<PAGE> 39
with such priority as, such holders may be entitled thereto under
applicable law, of an equitable Lien on such asset or property securing
the Notes, except where the effect thereof would in any way limit the
rights of the holders of Notes under this Agreement or the Other
Agreements. Such violation of this Section 10.2 shall constitute an Event
of Default whether or not any such provision shall be made as required by
this Section 10.2.

(including, without limitation, the purchase, sale, lease or exchange or
any property or the rendering of any service), with any Affiliate of the

or such Subsidiary, as the case may be, than those that would be obtainable
at the time in an arm's length transaction from any Person who is not
such an Affiliate.

            -------------------------------------------

     of the Borrower, and (ii) involving any other Subsidiary of the
     Borrower, in the event the surviving corporation is not the Subsidiary,
     such surviving corporation immediately thereafter becomes a Subsidiary

become due otherwise than by acceleration (with interest on all such overdue
principal and prepayment charge, if any, and, to the extent permitted by
law, on overdue payments of interest, at the applicable rate per annum
provided for in the Notes or this Agreement in respect of overdue amounts
of principal, prepayment charge and interest), and all Events of Default
(other than nonpayment of principal of, prepayment charge (if any) and
accrued interest on the Notes, due and payable solely by virtue of
acceleration) shall be remedied or waived pursuant to Section 15.2, then,
and in every such case, the Majority Holders, by written notice to the
Borrower, may rescind and annul any such acceleration and its consequences
with respect to the Notes; but no such action shall affect any subsequent
Default or Event of Default or impair any right consequent thereon.

     12.2.  Suits for Enforcement.  If any Event of Default shall have
            ---------------------
occurred and be continuing, the holder of any Note may proceed to protect
and enforce its rights, either by suit in equity or by action at law, or
both, whether for the specific performance of any covenant or agreement
contained in this Agreement or in aid of the exercise of any power granted
in this Agreement, or the holder of any Note may proceed to enforce the
payment of all sums due upon such Note or to enforce any other legal or
equitable right of the holders of such Note.

     The Borrower covenants that, if it shall default in the making of
any payment of principal of, or interest or prepayment charge on, any Note
or in the performance or observance of any agreement contained in this
Agreement, it will pay to the holder thereof such further amounts, to the
extent lawful, as shall be sufficient to pay the costs and expenses of
collection or of otherwise enforcing such holder's rights, including
reasonable counsel fees.

     12.3.  Remedies Cumulative.  No remedy herein conferred upon you or the
            -------------------
holder of any Note is intended to be exclusive of any other remedy and each
and every such remedy shall be cumulative and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity
or by statute or otherwise.

     12.4.  Remedies Not Waived.  No course of dealing between the Borrower
            -------------------
and you or any other holder of any Note and no delay or failure in exercising
any rights hereunder or under any Note in

                                    -53-
<PAGE> 59
respect thereof shall operate as a waiver of any of your rights or the rights
of any holder of such Note.

     Section 13.  Registration, Exchange, and Transfer of Notes.  The
                  ---------------------------------------------
Borrower will keep at its principal executive office a register, in which,
subject to such reasonable regulations as it may prescribe, but at its
expense (other than transfer taxes, if any), the Borrower will provide for
the registration and transfer of Notes. Whenever any Note or Notes shall be
surrendered either at the principal executive office of the Borrower, or at
the place of payment named in the Note, for transfer or exchange,
accompanied (if so required by the Borrower) by a written instrument of
transfer in form reasonably satisfactory to the Borrower duly executed by the
holder thereof or by such holder's attorney duly authorized in writing,
the Borrower will execute and deliver in exchange therefor a new Note or
Notes in such denominations (any such Note shall be in multiples of
$100,000 but the principal amount of any such Note shall in no event be
less than $500,000) as may be requested by such holder, of like tenor and in
the same aggregate unpaid principal amount as the aggregate unpaid principal
amount of the Note or Notes so surrendered. Any Note issued in exchange for
any other Note or upon transfer thereof shall carry the rights to unpaid
interest and interest to accrue which were carried by the Note so
exchanged or transferred, and neither gain nor loss of interest shall result
from any such transfer or exchange. Any transfer tax or governmental charge
relating to such transaction shall be paid by the holder requesting the
exchange. The Borrower and any of its agents may treat the Person in whose
name any Note is registered as the owner of such Note for the purpose of
receiving payment of the principal of, prepayment charge (if any) and interest
and other amounts on such Note and for all other purposes whatsoever,
whether or not such Note be overdue.

     Section 14.  Lost, Stolen, Damaged and Destroyed Notes.  At the request
                  -----------------------------------------
of any holder of any Note, the Borrower will issue and deliver at its
expense, in replacement of any Note or Notes lost, stolen, damaged or
destroyed, upon surrender thereof, if mutilated, a new Note or Notes in the
same aggregate unpaid principal amount, and otherwise of the same tenor, as
the Note or Notes so lost, stolen, damaged or destroyed, duly executed by the
Borrower. The Borrower may condition the replacement of a Note or Notes
reported by the holder thereof as lost, stolen, damaged or destroyed, upon
the receipt from such holder of an indemnity or security reasonably
satisfactory to the Borrower; provided, that if such holder shall be you or
                              --------
your nominee or another Eligible Holder or its nominee, your or such Eligible
Holder's unsecured agreement of indemnity shall be sufficient for purposes
of this Section.

     Section 15.  Miscellaneous.
                  -------------

     15.1.  Home Office Payment.  Notwithstanding anything to the contrary in
            -------------------
this Agreement or in the Notes, the Borrower agrees that, so long as you or
any nominee designated by you or any Eligible Holder shall hold any Notes,
the Borrower shall cause all payments of principal, prepayment charge (if any)
and interest on the Notes to be made, without presentment thereof, to you in
the manner and to the address specified in Schedule I hereto, or in such
other manner or to such other address as you or any Eligible Holder may
designate in writing. You agree that prior to the sale, transfer or
disposition of any Note you will make a notation thereon of the portion of
the principal amount paid or prepaid and the date to which interest has been
paid thereon or surrender the same in exchange for a new Note or Notes of the
same series, of the same tenor and of authorized denominations in principal
amount equal to the unpaid principal amount of the Note or Notes so
surrendered, duly executed by the Borrower. Notwithstanding anything herein
to the contrary, the Borrower shall not, as a condition of payment of all of
the principal of, Make-Whole Premium (if any) and interest on any Notes,
require you or any Eligible Holder, upon receipt of such payment in full, to
surrender such Notes, provided, however, that upon receipt of such payment
                      -----------------
in full by you or any Eligible Holder, such Notes held by you or any Eligible
Holder shall be deemed to be automatically cancelled, without any further
action on the part of the Borrower or you or any Eligible Holder. The Borrower
shall enter into an agreement similar to that contained in this Section with
any other English Holder (or nominee thereof).

     15.2.  Amendment and Waiver.
            --------------------

           (A)  Any term, covenant agreement or condition of this Agreement or
of the Notes may, with the consent of the Borrower be amended, or compliance
therewith may be waived (either generally or in a particular instance and
either retroactively or prospectively), by one or more substantially
concurrent written instruments signed by the Majority Holders, except that

              (1)  no such amendment or waiver shall (a) reduce the
     principal of, or the rate of interest on, any of the Notes, (b) extend
     the time of payment of all or any portion of the principal of or interest
     on or any prepayment charge payable with respect to any of the Notes,
     (c) modify any of the provisions of this Agreement or of the Notes with
     respect to the payment or prepayment of the principal thereof or
     prepayment charge or interest thereon, (d) reduce the percentage of Notes
     required with respect to any such amendment or to effectuate any such
     waiver, or (e) modify any

                                    -55-
<PAGE> 61
     provision of this Section, without in each case the specific prior
     written consent of the holders of all of the Notes at the time
     outstanding; and

              (2)  no such waiver shall extend to or affect any obligation
     not expressly waived or impair any right consequent thereon.

           (B)  Any amendment or waiver pursuant to Subsection (A) of this
Section 15.2 shall apply equally to all holders of the Notes at the time
outstanding and shall be binding upon them, upon each future holder of any
Note, and upon the Borrower, in each case whether or not a notation thereof
shall have been placed on any Note.

           (C)  Notwithstanding any other provision contained in this Section
15.2 or elsewhere in this Agreement to the contrary, Notes which at any
time are held by the Borrower or by any Subsidiary or Affiliate of the
Borrower shall not be deemed outstanding for purposes of any vote, consent,
approval, waiver or other action required or permitted to be taken by the
holders of Notes, or by any of them, under the provisions of this Section
15.2 or Section 12 of this Agreement, and neither the Borrower nor any such
Subsidiary or Affiliate shall be entitled to exercise any right as a holder
of Notes with respect to any such vote, consent, approval or waiver or to take
or participate in taking any such action at any time.

           (D)  So long as any Notes remain outstanding, the Borrower will
not solicit, request or negotiate for or with respect to any proposed consent
with respect to, or waiver or amendment of, any of the provisions of this
Agreement, the Other Agreements or the Notes unless each holder of Notes
(irrespective of the amount of Notes then owned by it) shall be informed
thereof by the Borrower and shall be afforded the opportunity of considering
the same and shall be supplied by the Borrower with sufficient information
to enable it to make an informed decision with respect thereto. The Borrower
will not, directly or indirectly, pay or cause to be paid any remuneration,
whether by way of supplemental or additional interest, fee or otherwise, to
any holder of Notes as consideration for or as an inducement to the entering
into by any holder of Notes of any amendment, waiver or consent with respect
to any of the terms and provisions of this Agreement, the Other Agreements
or the Notes unless such remuneration is currently paid, on the same terms,
ratably to the holders of all Notes then outstanding.

     15.3.  Expenses.  The Borrower agrees, whether or not the transactions
            --------
hereby contemplated shall be consummated, to pay and save you harmless
against any and all liability for the payment

                                    -56-
<PAGE> 62

Agreement and the other instruments and the transactions hereby contemplated,
including without limitation all such expenses incurred with respect to the

proposed consents, amendments or waivers (whether or not the same shall be
signed or shall become effective) under or in respect of any such agreement
or instrument, any workout or restructuring of the Debt or capital structure
of the Borrower (whether or not the same shall be consummated or shall become
effective) and the consideration of any legal questions relevant thereto, all
expenses incurred in connection with the reproduction of such agreements and
instruments and all stamp and other similar taxes (together in each case
with interest and penalties, if any) which may be payable in respect of the
execution and delivery of such agreement or instruments, or the issuance,
delivery or acquisition by you of any Note or otherwise pursuant to this
Agreement, and expenses incurred in obtaining a private placement number
from Standard & Poor's Corporation, and the fees and disbursements of
Sonnenschein Nath & Rosenthal and of any special or local counsel in
connection with preparation of such agreements and instruments and the
transactions hereby and thereby contemplated (including, without limitation,
in connection with any such enforcement, consent, amendment, waiver, workout,
restructuring or consideration of legal questions), and the fees and
disbursements of the Accountants. The obligations of the Borrower under this
Section 15.3 shall survive the payment or transfer of any Note, the
enforcement of any provision hereof or thereof, any such amendments or
waivers and any such consideration of legal questions.

     15.4.  Survival of Representations and Warranties.  All representations

successors and assigns of the parties hereto whether so expressed or not,
except that you shall not be obligated to purchase any Note from any issuer
other than the Borrower. The provisions of this Agreement are intended to
be for the benefit of all holders, from time to time, of any Notes purchased
pursuant hereto, and shall be enforceable by any

                                    -57-
<PAGE> 63
such holder, whether or not an express assignment to such holder of rights
under this Agreement has been made by you or your successor or assign.

DELIVERING ON COMMITMENTS          FOCUSING ON ENVIRONMENTAL OPPORTUNITIES

While protecting the quality of air, water and soil is of vital importance to
every industry, complying with the growing body of environmental regulation is
both increasingly difficult and costly.  The American Petroleum Institute
estimates the cost of environmental compliance efforts to its industry at $8
billion annually.
    The federal Clean Air Act, as one example, had significant impact on the
fuels industry in 1993.  Many suppliers were forced to reformulate their fuels
to meet new, more stringent vehicle exhaust specifications -- aimed primarily
at reducing

                                    10
<PAGE> 2
sulfur emissions, considered a key component in the formation of
acid rain and other environmental ills.
    As a result, incasing numbers of refiners, diesel fuel distributors,
marketers and specialty chemical companies turned to Petrolite to help them
achieve cost-effective compliance through specialized services, treatment
programs and performance additives.


Cleaner Diesel Fuels
Diesel fuels in particular had to be made cleaner-burning.  Reducing the
sulfur content of these fuels, however, raised fears among diesel engine
builders and operators that fuel pumps and other vital parts might wear out
prematurely for lack of sulfur as a friction reducer.  Petrolite is responding
to their concerns by providing lubricity additives that help protect both the
engines and the environment.
    Many fuel formulators have also had to resort to increased use of
detergents and dispersant to bring their fuels into compliance.
According to Michael Thorne, a fuels specialist for Petrolite, that
practice alone could cause these fuels during transportation and storage to
absorb more water, which could later freeze in fuel lines or form viscous
emulsions that could clog fuel filters.  Many major fuel blenders ar now
adding those components in combination with special multipurpose additives
carefully prescribed by Thorne and others at Petrolite to improve their
fuels' "water tolerance".


Communications = Results
"Very often we work directly with the customers' technical people to help
solve these problems," observes Thorne.  "In one instance, we had an urgent
request from a major fuel supplier to help them solve a serious water
tolerance problem.  Working together with them, communicating one-on-one, we
were able to provide a solution that positively delighted them.  Since then,
they have been calling us on other fuel related problems, and that positively
delights us -- to be helping them in these new areas."
    Providing customers with this sort of personalized, technical expertise
typifies what Petrolite does best.  Our people have the special know-how in
the area of fuel components chemistry and the state-of-the-art technical
resources necessary to help them solve their most difficult fuel performance
problems.
    Moreover, many of these same, new, air quality specifications -- or more
stringent versions of them -- may eventually be adopted in Europe and
elsewhere as environmental awareness grows. Wherever and whenever that
happens, Petrolite is prepared to provide its customers with the services they
require.


Another Culprit, H2S
Airborne sulfur emissions in the form of poisonous hydrogen sulfide (H2S) gas
is another area of concern for the hydrocarbon process and fuels industries in
the United States, especially where high-sulfur fuel feedstocks are
transported and stored.
    Specifically, Petrolite is providing shippers, terminal operators and
others with a unique, rapid-response service that effectively helps neutralize
this deadly contaminant.
    At the same time, Petrolite is working on a revolutionary new method of
mitigating sulfur emissions problems.  For nearly two years, we have been
involved in a technical alliance with Energy BioSystems Corporation of Houston
in an effort to commercialize a proprietary biocatalytic process to remove
sulfur from hydrocarbon feedstocks at a cost to customers far below that of
current technologies.  Progress to date has been encouraging and a pilot plant
is scheduled for construction late in 1994.

DELIVERING ON COMMITMENTS                    FOCUSING ON ACQUISITIONS

Petrolite negotiated three strategic acquisitions in 1993 that strongly
complement our core business and technology.  These synergies are most evident
in the Welchem acquisition which is creating added value for customers,
especially our largest, Amoco Corporation.
    A subsidiary of Amoco Chemical holding Company since 1982, Welchem was
providing a full range of specialty chemical services to oil and gas producers
and refiners.  While a significant portion of its customers were "outside"
accounts, the majority of them -- comprising the bulk of its approximately $52
million in sales in 1992 -- were Amoco units.


Building Bridges to Amoco
Petrolite too has been a longtime Amoco supplier, and our acquisition of
Welchem was intended to build more and stronger bridges to Amoco's worldwide
organization.  That is happening now all across the United States and in the
Caribbean, Canada, Africa and Europe.  Illustrative is an alliance agreement,
signed October 1, between Petrolite and Amoco-Netherlands to service its oil
production in the North Sea.
    "I think this decision to go with Petrolite  was most strongly influenced
by our track record in other alliances, especially our work with Chevron in
the North Sea," says Stuart Monro, general

<PAGE> 4
manager of Petrolite's EuroChem Division, "but certainly the Welchem
acquisition was a factor in their selection process".
    There were other acquisition benefits as well.  Welchem's blend plant,
offices and laboratory in Edmonton, Alberta, Canada, precluded our need to
follow through on plans to build there to serve that attractive market.  The
successful integration of Welchem into our own organization also added
significantly to the ranks of talented management and field staff serving the
needs of Petrolite customers.


Vendor of the Year
A good example is Don Porterfield, a Petrolite field sales representative in
West Texas.  A former Welchem employee, Porterfield was honored in 1993 by
Amoco as "Vendor of the Year" in its Permian Basin North District.
    Jerome Powers, a field foreman for Amoco, explains that this award was
a first for its unit and that the choice of Porterfield was unanimous.  "He
works very closely with us," Powers says. "Any time of day or night that we
need him, he's out here.  His attitude is great, and he's always coming up
with ways to save us money."
    Service offerings also have been improved with former Welchem customers
now having access to Petrolite's expansive technical resources.  Petrolite,
in turn, acquired new proprietary process and product technologies that are
important to sustaining ongoing treatment programs at Amoco installations and
elsewhere.


A Natural Fit
Jim Zemenick, vice president of corporate development who led Petrolite's
acquisition efforts, points out that "the Welchem purchase was such a natural
fit with our organization, that it would be hard to imagine that it could have
been anything other than a benefit to our customers and a success for us."
    The two other acquisitions in fiscal 1993 were also excellent fits:
Chemical Specialties Corporation of Louisiana effectively serves oil and gas
producers, especially those operating off the U.S. Gulf Coast; the purchase of
Sulfa-Scrub(R) product patents from Quaker Chemical Corp. enhances our
hydrogen sulfide removal technology.

</TABLE>
Petrolite's revenues rose 11% in fiscal 1993 to $351,779,000.  All of the
Company's operating divisions participated in the revenue improvement.  About
50% of the increase came from the acquisition of Welchem, Inc., a subsidiary
of Amoco Chemical Company, which was completed in April, 1993.
    Net earnings in fiscal 1993, before effect of a change in accounting
principle, increased 25% to $20,546,000, or $1.82 per share, compared with
$16,479,000, or $1.45 per share, in the prior period.  All operating divisions
also shared in the earnings improvement.
    In the fiscal 1993 first quarter, Petrolite adopted Statement of Financial
Accounting Standard 106 related to medical and other post-retirement benefits,
which resulted in a nonrecurring, non-cash, after-tax charge of $6,500,000, or
$.58 per share.  This charge reduced reported fiscal 1993 earnings to
$14,046,000, or $1.24 per share.

</TABLE>
Revenues from sales of Specialty Chemical Products were $332,512,000 in fiscal
1993, a 10% increase over fiscal 1992.  New business gained as a result of the
Welchem acquisition accounted for approximately 60% of the improvement.  The
largest revenue increase was realized by the Tretolite Division principally
due to the Welchem acquisition.  New revenue sources also included hydrogen
sulfide management programs added to Petrolite's service offerings through
purchase of Sulfa-Scrub(R) patents and technology from Quaker Chemical
Corporation.
    The Industrial Chemicals Division also benefited from acquiring the
Welchem customer base.  In addition, there was continued strong demand for
fuel additives and its basic refinery product base.  Oilfield and industrial
chemicals sales also showed good improvement in Latin American markets and the
Pacific Rim.
    Major sales volume gains were realized by the EuroChem Division, although
a general decline in the value of European currencies versus the dollar diluted
the comparative revenue effect.  Larger revenue gains were in the Middle East,
Northern Europe and Africa.  The Polymers Division also posted higher revenues
in international markets which offset the impact of sluggish demand in
domestic markets.
    Equipment revenues were $19,267,000, a 17% increase over fiscal 1992.
Petreco Division equipment contract activity accelerated significantly,
particularly in Europe and the Pacific Rim.  The Division also enjoys a
healthy backlog of contracts to be realized in fiscal 1994.

</TABLE>
Operating earnings of Petrolite's Specialty Chemical Products business segment
improved 22% to $29,714,000 in fiscal 1993.  All divisions contributed to the
improvement.  Operating margins of the Tretolite and Industrial Chemicals
Divisions were higher due to more favorable product mix, stable raw material
costs, and the beneficial impact of higher sales volumes on fixed operating
costs.  There were also improved contributions from Latin America and the Far
East.
    The EuroChem Division significantly improved its profitability, despite the
effect of generally weaker currencies on revenues.  Operating earnings of the
Polymers Division improved on higher revenues, while margins were tested by
intense competition in several product lines.
    The company's Equipment segment generated operating earnings of $1,851,000,
representing a 38% gain over the prior year.  Stronger Equipment revenues
produced by the company's European subsidiaries were a major factor in the
improvement.
    Operating earnings in 1992 were impacted by the two non-recurring items
indicated.

In fiscal 1993, Petrolite realized steady, quarterly improvements in its
revenues, net earnings and earnings per share.  During the first quarter, the
company made an accounting change related to medical and other post-retirement
benefits which resulted in a one-time charge of $6.5 million, or $.58 per
share.  All divisions contributed to the growth in revenues and earnings for
the year.
    The Welchem acquisition was the major contributor to the increase in
revenues and gross profit in the last two quarters of fiscal 1993, although
higher operating expenses  transitional costs and financing costs offset most
of these gains.  With full assimilation of Welchem activities into Petrolite
operations, this acquisition is expected to make a greater contribution to
earnings in fiscal 1994 and future periods.
    The first quarter of fiscal 1992 included two non-recurring items which
significantly affected quarterly results.  A loss on sale of assets of a
small, non-productive subsidiary reduced earnings by $.15 per share.  This
charge was partially offset by a gain of $.06 per share from termination of a
subsidiary's pension plan, which was replaced by an improved benefit plan.
    Overall, the fiscal 1992 improvement was achieved through strong
performance in international markets partially offset by slow domestic
oilfield and refinery markets.

</TABLE>
The company's exchange gains and losses were principally attributable to the
effects of changes in value of the U.S. dollar-denominated asset and liability
accounts of its foreign subsidiaries and closing of foreign currency futures
contracts.  The company uses several measures to protect returns on its
foreign subsidiary net assets from significant changes in the value of the
dollar versus foreign currencies.  These measures include pricing adjustments,
maintenance of offsetting asset and liability balances, and investment in
foreign currency futures contracts.  There were no significant contracts
outstanding at year end.  Balance sheet changes in the cumulative translation
adjustment reflect the general overall increase in the value of the
U.S. dollar versus foreign currencies in all three years.

</TABLE>
While the company's total debt increased significantly in 1993 to finance its
business and technology acquisition programs, its ratio of debt to total
capital remained  comparatively low.  Petrolite's continuing strong financial
position and adequate credit availability provide a high degree of flexibility
in obtaining additional funds on competitive terms.  Historically the company
has financed growth in its asset base and dividends to stockholders primarily
from internally generated funds.  With its strategic change to a more
aggressive acquisition program, external financing is likely to continue to
increase.

Petrolite Corporation is a member of the NASDAQ National Market System of
over-the-counter securities.  The company's capital stock is traded under the
symbol PLIT.  As of October 29, 1993, Petrolite has 2,288 shareholders of
record.

PRIOR YEAR'S OPERATING RESULTS

1992 vs. 1991
Petrolite's fiscal 1992 revenues were $317,950,000, a 2% decrease from fiscal
1991.  EuroChem Division's revenues were higher in the period.  Revenues of
the other operating divisions were slightly lower than those established in
fiscal 1991, which was the company's record revenue year.
    Net earnings in fiscal 1992 rose 12% to $16,479,000, or $1.45 per share,
an increase of $1,722,000, or $.15 per share, from fiscal 1991.  The EuroChem
Division realized the greatest earnings improvement while the Polymers and
Industrial Chemical Divisions also registered higher profits.  The Tretolite
and Petreco Divisions' earnings were lower for the period.
    The year's results were affected by two non-recurring items occurring in
the first quarter.  These included a charge of $2,618,000, $.15 per share, from
the sale of assets of an unprofitable subsidiary, partially offset by a gain
of $1,262,000, $.06 per share, from the termination of a subsidiary's pension
plan that was replaced by an improved benefit plan.
    Net revenues from sales of Specialty Chemical Products were $301,484,000,
approximately the same as fiscal 1991.  The major revenue gain was recorded by
the EuroChem Division, where sales to the Middle East and Africa were
exceptionally strong.  Tretolite Division's revenues were lower, reflecting
softness in domestic Oil Field markets. Oil Field Chemical sales in Pacific
Rim countries showed good improvement.  The rate of decline in domestic
revenues of the Tretolite Division was less than the overall decline in the
domestic market for Oil Field chemicals.
    Revenues of the Industrial Chemicals and Polymers Divisions were comparable
to fiscal 1991 while realizing some gains in target markets.  The Industrial
Chemicals Division was adversely affected by the slowdown in U.S. refinery
activity.  Polymers Division's revenues reflected generally slow economic
conditions but showed an encouraging upturn in the latter months of the year.
    Equipment revenues were $16,466,000, 13% lower than fiscal 1991.  The
year-end backlog of equipment contracts and other accelerated Petreco Division
activities, particularly in Europe and the Pacific Rim, indicate a turnaround
in fiscal 1993.
    Operating earnings of Petrolite's Specialty Chemical Products business
segment improved 10% to $24,410,000 in fiscal 1992.  EuroChem Division
operating results rose significantly due to a 7% increase in revenues and
continuing effects of significant cost reduction actions taken in fiscal 1991.
    The Industrial Chemicals Division and the Polymers Division realized higher
operating earnings with comparable revenues due to improvements in product
mix. Tretolite Division operating earnings were lower due to lower revenues.
    All Specialty Chemicals Products operating divisions benefited from
improved stability of raw material costs in fiscal 1992.
    The company's Equipment segment generated an operating profit of
$1,343,000 in fiscal 1992 compared with $2,174,000 in the prior year.  The
decline was attributed to lower contract revenues which are expected to turn
around in fiscal 1993.

1991 vs. 1990
Petrolite's fiscal 1991 revenues improved to $323,516,000, a 9% increase from
fiscal 1990.  Each of the company's five operating divisions contributed to
the revenue growth.
    Net earnings in fiscal 1991 rose 12% to $14,757,000, or $1.30 per share,
an increase of $1,622,000 or $.14 per share, from fiscal 1990. All five
operating divisions showed higher profits.
    Net revenues from Specialty Chemical Products' sales improved 9% in 1991 to
$304,550,000.  The largest revenue growth occurred in the Tretolite Division
where recent concentrated efforts to more effectively market our products and
provide a higher level of field technical service began to produce results.
Substantially higher sales of fuel additives and an improved product mix were
major factors in the Industrial  Chemicals Division's revenue growth.  The
EuroChem Division's Oil Field Chemical sales were particularly strong in
Africa and the Middle East.  Polymers Divisions revenues were higher
world-wide despite generally slow economic conditions which typically impact
this business.
    Equipment revenues were $18,966,000, 8% higher than fiscal 1990.  Petreco
Division's contract revenues were significantly higher both in the United
States and internationally.
    At year end major international equipment contracts were in progress in
Saudi Arabia and Venezuela.  The revenue improvement would have been greater
except for the abandonment or disposition of several product lines in early
1991 and 1990.
    Operating earnings of Petrolite's Specialty Chemical Products business
segment improved 27% to $22,244,000 in fiscal 1991.  Tretolite  Division
operating results were sharply higher due to a 7% increase in sales volumes
and the leveraging effect of the additional volume on the division's fixed
expenses. The Industrial Chemicals Division realized increased operating
earnings with comparable volumes but an overall improvement in product mix.
    Substantially higher operating profits were realized by the EuroChem
Division as a result of a 14% increase in sales volumes.  Earnings from
operations increased in the Polymers Division due to higher sales revenues,
effective control of operating expenses, and the comparative effect of costs
incurred in the prior year due to a plant explosion.
    All Specialty Chemical Product operating divisions were favorably impacted
by improved stability of raw material costs in fiscal 1991.
    The company's Equipment segment produced an operating profit of $2,174,000
in fiscal 1991, which was 80% higher than comparable operating results in the
prior year.  The increase was attributable to a significantly greater
contribution from contract revenues and improved control of operating
expenses.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

- -------------------------------------------------------------------------------
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation
The consolidated statements include the accounts of the company,
its subsidiaries and its unconsolidated corporate affiliates,
Toyo-Petrolite Co. Ltd. and Petrolite Suramericana, S.A.,
which are accounted for using the equity method.  All significant
intercompany accounts and transactions have been eliminated.


Translation of Foreign Currencies
Foreign currency translations and financial statments are
translated in accordance with Statement of Financial Accounting
Standards No. 52.  Under this standard all assets and liabilities
of operations outside the United States, except for
operations in highly inflationary economies, are translated into
U.S. dollars at exchange rates in effect at the end of the period.
Operating results are translated at a weighted average of
exchange rates in effect during the year.  Net unrealized gains
and losses on translation of foreign currency financial statements,
other than those in highly inflationary economies, are
recorded in stockholders' equity, as a cumulative translation
adjustment, and will be included in income only upon sale or
liquidation of the underlying asset.  Realized gains and losses
resulting from completed transactions are included in net
earnings.


Cash Equivalents
Cash equivalents are comprised of highly liquid debt instruments
with a maturity of three months or less.


Inventories
Inventories are valued at the lower of cost or market.  Cost is
determined under the last-in, first-out (LIFO) method for most
domestic inventories of Specialty Chemical Products.  The
remainder is stated at standard cost, which approximates
actual cost, or at actual cost.  Standard costs are determined on
a fully-absorbed basis.


Intangibles
Patents and other intangibles are amortized on a straight line
basis over periods ranging from 4 to 15 years.


Properties and Depreciation
Properties are carried at cost and include expenditures for
new facilities and those which substantially extend the useful
lives of existing capital assets.  Maintenance, repairs and minor
renewals are expensed as incurred.  Upon disposal or retire-
ment of properties, the related cost and accumulated depreciation
are removed from the accounts and any profit or loss on
disposition is recorded in income.  Depreciation is generally
provided on a straight-line basis at rates based on estimated
useful lives of the properties (buildings 5 to 50 years, machinery
and equipment 3 to 20 years).


Income Taxes
The company follows the practice of providing for income
taxes based on financial statement earnings.  Consolidated
income taxes include provisions for additional taxes or tax
refunds on repatriation of income earned abroad and also
reflect the deferred tax effect of accelerated depreciation and
other timing differences in reporting income and deductions
for tax purposes.

Capital Stock
Proceeds from sales of capital stock issued under stock option
and incentive plans and tax benefits to the company resulting
from early disposition of stock acquired by the employees
under options are credited to capital stock.  Proceeds in excess
of cost from sales of treasury stock are also credited to capital
stock.


Revenue Recognition
The company follows the practice of reporting income from
equipment contracts on the percentage-of-completion method.
Revenue other than equipment contracts, is recorded based on
shipment date.


Earnings Per Share
Net earnings per share are based on the weighted average
number of shares of capital stock outstanding during the
respective year.


Financial Statement Reclassification
Selected prior year information has been reclassified to
conform with 1993 annual report presentation.


SUMMARY OF OTHER FINANCIAL DATA

Concentration of Credit Risk
The company sells a majority of its products to customers in
the oil and gas industry.  While most of the company's business
activity is with customers located within North America, the
company also services customers in Europe, Africa, the
Middle East, Far East, and South America.  The company performs
ongoing credit evaluations of its customers and generally does
not require collateral.  When appropriate, the company requires
letters of credit or other similar guarantees particularly
in international transactions.  The company maintains
reserves for potential credit losses and such losses have been
within management's expectations.  As of October 31, 1993,
the company had no significant concentrations of credit risk.


Financial Instruments
The fair value of financial instruments is determined by
reference to various market data and other valuation techniques
as appropriate.  Unless otherwise disclosed, the fair values of
financial instruments approximate their recorded values.
Marketable securities are stated at their approximate market value.

ACQUISITIONS
On April 14, 1993 the company completed its acquisition of certain
assets and liabilities of Welchem, Inc., a wholly-owned subsidiary of Amoco
Chemical Holding Company. Results of operations for Welchem are included in
the company's Consolidated Statement of Earnings from the date of acquisition.
The assets acquired by the company include assets owned by Welchem, Inc. and
certain other of Welchem's affiliates which are used in the manufacture and
sale of oil and gas exploration and production chemicals, chemical
manufacturing and petroleum refining chemicals, custom-blended and
toll-manufactured chemicals and the provision of related services.  The
consideration paid by the company was $33,140,000, subject to a post-closing
adjustment for variables in inventory and accounts receivable.
    The acquisition was recorded using the purchase method of accounting.
Accordingly, the purchase price has been allocated to the assets and
liabilities acquired based on their estimated fair values at the date of
acquisition.  The assets included certain property, plant, and equipment
utilized in the business. Certain intangible assets acquired are being
amortized over periods ranging between 5 and 14 years on a straight-line
basis.
    The sources of funds utilized by the company for the acquisition were
borrowings under lines of credit from various banks which were refinanced
through a long term debt private placement in November, 1993.
    The following summary, prepared on a pro forma basis, combines the
consolidated results of operations as if Welchem had been acquired prior to
November 1, 1991, after including the impact of certain adjustments such as
projected savings from consolidation of functions and facilities, amortization
of intangibles, increased interest expense on the acquisition of debt, and the
related income tax effects.

The pro forma results are not necessarily indicative of what actually
would have occurred if the acquisition had been in effect for the entire
periods presented.  In addition, they are not intended to be a projection of
future results.
    In July, 1993, the company purchased Sulfa-Scrub(R) patents and technology
from Quaker Chemical Corporation. These patents are being amortized over 15
years on a straight-line basis.  Pro forma results of this acquisition would
not be materially different from the results included in the Consolidated
Statement of Earnings.


INVENTORIES

<TABLE>
Inventories at October 31 are summarized as follows:

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
</TABLE>
The overall increase in inventories in 1993 principally reflects additional
raw materials and products to support new business gained in 1993 primarily
through acquisitions.  Equipment contracts in progress were lower at year-
end 1993 due to a change in mix of jobs in progress at the respective
year-end dates.
    Approximately 75% and 70% of total inventories (exclusive of equipment
contracts in progress) were accounted for on a last-in, first-out (LIFO) basis
at October 31, 1993 and 1992, respectively.


SHORT-TERM BORROWINGS AND LINES OF CREDIT

Short-term funds for certain international operations are obtained
through unsecured overdraft facilities and short-term notes payable with local
banks and totaled $2,220,000, at October 31, 1993.  Domestic short-term funds
are obtained through unsecured lines of credit with two banks authorizing
borrowings bearing interest at a fluctuating rate below prime determined by
the banks' cost of funds.  These lines of credit were increased to a total of
$66 million during fiscal 1993 for acquisition financing and general corporate
purposes, and require a commitment fee on certain unused portions.  At October
31, 1993, the amount available and unused under these lines of credit
aggregated $18.3 million.  The fair value of the company's short term
borrowings approximate the carrying amount.
    The consolidated balance sheet at October 31, 1993 includes a
reclassification of $40.0 million of short-term debt reflecting the company's
refinancing of this debt on a long-term basis on November 5, 1993.


LONG-TERM DEBT

In September, 1993, the company entered into a Note Purchase Agreement
with several institutional investors providing for the private placement of
its 5.90% Series A Senior Notes due 2000 and 6.39% Series A Senior Notes due
2003 in aggregate principal amounts of $10 million and $30 million,
respectively.  Proceeds from the sale of these unsecured notes, which were
issued in November, 1993, were used to retire short-term borrowings.
    The Note Purchase Agreement contains certain restrictive covenants
including limitations on additional borrowings and disposition of assets, and
the maintenance of minimum net worth.  Long-term debt maturities are (in
millions):  fiscal 1994

Income taxes paid during 1993, 1992, and 1991 totaled
$8,123,000, $9,394,000 and $5,988,000, respectively.
    In February 1992, the Financial Accounting Standards
Board issued Statement 109, "Accounting for
Income Taxes".  Standard 109 will change the company's
method of accounting for income taxes from the deferred
method (APB 11) to an asset and liability approach.
    The FASB has deferred mandatory implementation
of this statement until fiscal 1994.  The estimated cumulative
effect of implementing the new standard, using current
tax rates, will be to reduce the net deferred tax liability
by approximately $2 million.
    U.S. federal income tax returns for all years through 1991
have been settled with the Internal Revenue Service.

POST-EMPLOYMENT BENEFITS
The company has a noncontributory final average pay defined benefit plan
covering all eligible U.S. employees. Certain benefit improvements under the
plan were initiated for current employees as of November 1, 1991, and for most
retirees as of January 1, 1992.  The company contributes funds to trustees as
necessary to provide for current service and for any unfunded prior service
costs over a reasonable period.  To the extent that these requirements are
fully covered by assets on hand, a contribution may not be made in a particular
year.  Plan assets consist principally of common stocks and fixed income
securities.  Pension costs for non-U.S. plans are not material in the aggregate
and are not included in these disclosures.

    The projected benefit obligation was determined using a discount rate of
7.5% for fiscal 1993 and 8.25% for fiscal 1992 and 1991.  The assumed
long-term rate of return on plan assets is 8.5% and the assumed long-term rate
of compensation increases is 5.0% for fiscal 1993 and 6.0% for fiscal 1992 and
1991.  The net transition asset at November 1, 1985 is being amortized over
19 years.
    Consolidated pension expense was $506,000 for 1993, $364,000 for 1992, and
$421,000 for 1991.


POST-RETIREMENT BENEFITS
The company implemented Statement of Financial Accounting  Standards No. 106
(SFAS 106), "Employers' Accounting for Post-retirement Benefits Other Than
Pensions", effective for fiscal 1993.  The company elected to immediately
recognize its transition obligation of $9,660,000 as the effect of a change in
method of accounting.  SFAS 106 requires recognition during employees' active
service periods of the expected cost of providing post-retirement benefits
(primarily health benefits).  The company's previous practice was to expense
these costs as they were paid.  Post-retirement health benefits are provided to
current and former employees and their spouses who retire at or after age 55
with 10 years of service.  The post-retirement health care plans are
contributory, based upon service at retirement and are subject to deductibles
and co-payments.  The company reserves the right to change or terminate the
benefits at any time.  The plan is funded as claims are paid.

1991.

    For measurement purposes, a health care cost trend of 13.0% was assumed for
1993, grading down gradually over the next seven years to 6.0% and remaining
at that level thereafter.  The health care cost trend rate has an effect on
the accumulated post-retirement benefit obligation and net periodic cost for
health benefits.  A one-percentage-point increase in the assumed health care
cost trend rates would increase the accumulated post-retirement benefit
obligation for health benefits at November 1, 1992 by $169,000 and would
increase the aggregate of the service and interest cost components of net
periodic post-retirement benefit cost for health benefits for 1993 by $17,000.
The discount rate used in determining the accumulated post-retirement benefit
obligation at the November 1, 1992, and in determining fiscal 1993 net periodic
post-retirement medical benefit cost was 8.25%.  The discount rate used for the
October 31, 1993 measurement was 7.5%.


STOCK OPTION PLANS
On December 10, 1986, the company's Board of Directors approved the 1987
Incentive Stock Option Plan.  Under this plan, 600,000 shares of unissued stock
were reserved for grant to officers and key employees and may be awarded in the
form of stock options or restricted stock units.
     Stock options are granted at prices not less than 100% of fair market
value of stock on dates of grant and are issued with a fixed expiration date,
not to exceed 11 years from date of grant.  Options are exercisable ratably in
annual installments of 25% commencing one year from date of grant.
     A restricted stock unit is the right to receive either cash or shares of
capital stock, upon fulfillment of certain conditions, without payment to the
company.  Restricted stock units are contingent upon continued employment or
attainment of predetermined performance targets during a restriction period of
generally three years.  Restrictions on exercise of stock options and
contingencies pertaining to restricted stock units will be mitigated if the
majority of the company's capital stock is acquired by another person or group.

     No additional grants will be made under this plan.  Transactions under the
1987 Incentive Stock Option Plan are summarized below:

</TABLE>
Under the 1993 Stock Incentive Plan, which was approved by the
shareholders on March 1, 1993,  800,000 shares of unissued stock were reserved
for grant to executive officers, key managers and non-employee members of the
Board of Directors and may be awarded in the form of stock options or
restricted stock units.  The plan provides that stock options are granted at
prices not less than 100% of fair market value

                                    27
<PAGE> 19
of stock on dates of grant and
are issued with a fixed expiration date, not to exceed 10 years from date of
grant.
     Annually, each member of the Board of Directors who is not an employee
of the company and who is elected at an annual shareholders meeting, receives
an option to purchase 2,000 shares of the company's capital stock, subject to
the five year term of the plan.
     On June 9, 1993, the Board of Directors granted two groups of options
under the 1993 plan with different performance criteria.  The first group of
options is keyed to annual increases in the value of the company's shares,
which consists of the market price plus dividends paid.  Options to purchase
410,000 shares are exercisable in five years, however, the exercise date may be
accelerated if certain criteria are met.  The second group of options is keyed
to the increase in the value of the company's shares over a five year period
commencing on June 9, 1993, the date of the grant.  Options to purchase
200,000 shares are exercisable in five years, however, the actual number of
shares which can be purchased under the plan will depend on the annual growth
in the value of the company's stock.
     During fiscal 1993, the company granted 610,000 stock options at an
exercise price of $32.875 per share and 28,000 stock options at an exercise
price of $29.00 per share.


ENVIRONMENTAL AND OTHER CONTINGENCIES
Various claims, lawsuits and other legal and administrative
proceedings, arising in the ordinary course of business, are pending against
the company.  The amount of the company's liability, if any, from such
proceedings cannot be determined at this time; however, management and legal
counsel are of the opinion that the ultimate disposition of such proceedings
including environmental  matters will not have a material adverse effect on
the consolidated financial position or results of operations of the company.


SEGMENT INFORMATION
Statement of Financial Accounting Standards No. 14 requires disclosure of
certain industry and world area "segment data." Accordingly, industry segment
and worldwide operations data appearing on pages 18 and 19 of this annual
report are an integral part of the accompanying financial statements.
     Earnings from operations reported under industry segment data have been
charged with corporate expenses of approximately $6.8 million, $6.3 million and
$10.3 million in 1993, 1992 and 1991, respectively, of which approximately 90%
was allocated to the Specialty Chemical Products segment each year.  These
corporate expenses consisted primarily of administrative costs which were
allocated to segments based upon services provided.
     Profitability of the company's foreign operations by geographic area, as
reported on page 19 of this annual report, was determined based on ultimate
sales to unaffiliated customers.  Total company profit was included in the
geographic area of the entity transacting the final sale.

RESPONSIBILITY FOR FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------
The management of Petrolite is responsible for the integrity and objectivity
of the financial statements of the company and its subsidiaries. The
accompanying financial statements, including the notes, were prepared
by the company in conformity with generally accepted accounting
principles, appropriate in the circumstances, and necessarily include
some amounts that are based on our best estimates and judgements.
The financial information in the remainder of this annual report
is consistent with the financial statements.
     The company maintains a system of internal accounting control
designed and intended to provide reasonable assurance that assets
are safeguarded and transactions are executed and recorded in
accordance with management's authorization. The system is tested
and evaluated regularly by the company's internal auditors as well
as by its independent accountants, Price Waterhouse, in connection
with their annual audit.
     The adequacy of the company's internal financial controls and
the accounting principles employed in financial reporting are
under the general surveillance of the Audit Committee of the
Board of Directors, consisting of three outside directors and
two advisory directors. The independent accountants and internal
auditors have free and direct access to the Audit Committee and
meet with the committee periodically, with and without
management present, to discuss accounting, auditing and financial
reporting matters. The committee also recommends appointment of
the independent accountants to the Board of Directors.

Petrolite Corporation

REPORT OF INDEPENDENT ACCOUNTANTS

     To the Stockholders and Directors of
     Petrolite Corporation

In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of earnings, of changes in
stockholders' equity and of cash flows present fairly, in all
material respects, the financial position of Petrolite Corporation
and its subsidiaries at October 31, 1993 and 1992, and the results
of their operations and their cash flows for each of the three
years in the period ended October 31, 1993, in conformity with
generally accepted accounting principles. These financial
statements are the responsibility of Petrolite's management;
our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining on a test basis, evidence
supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable
basis for the opinion expressed above.
     As discussed in the post-retirement benefits footnote to the
consolidated financial statements, in 1993 the company changed
its method of accounting for post-retirement benefit costs other
than pensions.
