the operation of the MMT Facility (the "Coordinator"). The Ethyl Coordinator or
his designee shall provide to Albemarle through Albemarle's Orangeburg Plant
manager and/or operations manager input concerning Ethyl's Raw Material and
finished goods inventory levels and advice and suggestions concerning cost
reduction and other plant improvement programs, product quality, shipment
instructions, deliveries, loading and unloading, procedures and such other areas
of interest that may be reasonably desired by Ethyl.

     5.02 The Ethyl Coordinator or his designee shall be kept advised by
Albemarle's operations manager and/or the Orangeburg Plant manager as to all
significant matters that relate to the operation of the MMT Facility while
producing MMT to be supplied to Ethyl including, without limitation, daily
operating logs and reports, control information (including statistical process

reasonably request.

     5.03 Albemarle's operations manager and the Orangeburg Plant manager will
give due consideration to suggestions made by the Coordinator or his designee
with respect to the operation of the MMT Facility, provided, however, that
Albemarle shall not be obligated to follow any suggestion of the Coordinator
which Albemarle reasonably believes would create or increase a material health
or safety risk or threat to the environment or which would violate applicable
laws or regulations or cause a material increase in Albemarle's cost of
operating the MMT Facility which is not reimbursed by Ethyl.

     5.04 From time to time, the Coordinator or his designee and Albemarle's
Orangeburg plant manager or Albemarle's operations manager shall meet to review

     5.05 In addition to the input, suggestions and advice given by the
Coordinator or his designee hereunder, as may be necessary to maintain smooth
coordination, it is expected that communications between other designated
parties representing Ethyl and Albemarle will be arranged to consider any matter
of concern either party wishes to have reviewed.

     5.06 Ethyl and Albemarle shall each consult, cooperate and work with the
other to produce MMT supplied to Ethyl under the terms of this Agreement in a
cost-efficient and effective manner while complying with applicable laws and
regulations.

ARTICLE 6 - ACCESS.

     The Coordinator shall have access to the Orangeburg, Plant facilities to
the extent necessary to utilize his office at the Orangeburg Plant as provided
in the Orangeburg Operating Agreement and the Antioxidant Supply Agreement to
perform his functions under this Agreement as well. The Coordinator shall not
have any right to access to any part of the Orangeburg Plant facilities other
than the MMT Facility and those other facilities to which the Ethyl Coordinator
has been granted access under the provisions of the Orangeburg Operating
Agreement, the Blending Services Agreement and the Antioxidant Supply Agreement
and those additional areas where his job requires his presence, which areas
include without limitation, the loading docks, storage areas, associated
pipelines, quality control laboratory, blending and drumming facilities, without
the prior consent of the Orangeburg Plant manager.

ARTICLE 7 - RAW MATERIALS.

     7.01 Except for specific raw materials which will be purchased by Ethyl
which are listed on Exhibit C attached hereto, all raw materials, chemicals and
other materials used to produce MMT ("Raw Materials") will be provided by
Albemarle in such quantities as will

                                      -5-

<PAGE>

enable Albemarle to sustain a production rate of MMT to meet Ethyl's
requirements. All Raw Materials, whether purchased by Ethyl or Albemarle, shall
meet Ethyls Raw Materials specifications in effect prior to the Closing Date as
modified by mutual agreement. Should Ethyl decide to purchase Raw Materials not
included on Exhibit C. Ethyl shall provide Albemarle not less than ninety (90)
days prior written notice of its intention to purchase such Raw Materials, and
such Raw Materials shall be added to Exhibit C and will thereafter be purchased
by Ethyl. Once Ethyl has elected to add a Raw Material to Exhibit C, Ethyl may
not thereafter remove a Raw Material from Exhibit C (and require Albemarle to
supply the Raw Material) without Albemarle's prior written consent. If in
electing to add a Raw Material to Exhibit C, Albemarle is required to cancel or
terminate any contract for the supply of such Raw Materials, Albemarle shall
notify Ethyl within said ninety (90) day period and Ethyl shall reimburse
Albemarle for such costs directly resulting from such cancellation or
termination, provided, however, that unless Ethyl has previously agreed to
Albemarle entering into such contract, Ethyl's liability for cancellation or
termination costs will be limited to those cancellation and termination costs
which would be applicable if the contract in question was no longer than one (1)
year in duration and requires the purchase of no more than [REDACTED]
([REDACTED] %) percent of Ethyl's annual requirements for such Raw Materials.
For purposes of this Agreement, all contracts for Raw Materials in effect on the
Closing Date, have been agreed to by Ethyl for the term of the contracts without
renewals or extensions. All remaining inventory of Raw Materials dedicated to
the performance of this Agreement purchased by Albemarle prior to the effective
date of Ethyl's decision to purchase Raw Materials shall be used by Albemarle to
make MMT for Ethyl and the cost of these Raw Materials shall be a Reimbursable
Cost until such inventory is depleted. Should Albemarle at any time desire to
purchase from Ethyl certain of the Raw Materials listed

                                      -6-

<PAGE>

on Exhibit C (as may be amended) for its own use, it will provide Ethyl no less
than ninety (90) days written notice of its intent to purchase such Raw
Materials. Ethyl agrees, subject to the terms of its supply contracts for such
Raw Materials and product availability in excess of Ethyl's requirements, to
sell such Raw Materials to Albemarle under its standard terms and conditions of
sale. The price for such Raw Materials shall be Ethyl's cost. Should Albemarle
terminate purchasing of such Raw Materials from Ethyl, Ethyl shall have no
further obligation to supply such materials during the term of this Agreement.
Should Ethyl terminate this Agreement pursuant to Section 3.01, Ethyl's
obligation to supply Raw Materials to Albemarle shall also terminate. Promptly
after notice of Ethyl's termination is received by Albemarle, the parties will
enter good faith negotiations to evaluate alternatives to provide Albemarle with
a source of the Raw Materials previously purchased from Ethyl. In administering
the above Raw Material purchase provisions, Albemarle and Ethyl shall at all
time use their good faith reasonable efforts, consistent with applicable law, to
minimize the effect of Raw Materials purchases and changes therein on both
Albemarle and Ethyl and to minimize Raw Material purchase cost to both Albemarle
and Ethyl.

     7.02 Albemarle will maintain proper inventory level records of each Raw
Material used to manufacture MMT as well as the production of MMT and update
such records on a monthly basis and correct the inventories each quarter by
actual physical count.

     7.03 If the parties disagree on recorded or reported Raw Material or MMT
inventories, the parties shall use their reasonable efforts to resolve promptly
any such disagreement.

Corrections to the accounting records required by such resolution shall be made
in the following month so as not to delay monthly closings.

ARTICLE 8 - MANUFACTURE OF MMT.

     8.01 Under the terms of this Agreement, Albemarle shall produce MMT meeting
specifications in effect on the Closing Date or mutually agreed upon as provided
below through good faith negotiations. Such specifications shall be incorporated
into Exhibit A attached hereto. Albemarle shall use its reasonable efforts to
operate processes that are statistically under control with a CPK of 1.3 or
higher on mutually agreed variables. A variability reduction plan will be
prepared annually by Albemarle to bring out of control processes under control.
Albemarle shall use reasonable good faith efforts to operate the MMT Facility
while producing MMT for sale to Ethyl in conformance with ISO 9002 approval
status.

     8.02 The specifications for Raw Materials and MMT manufactured at the MMT
Facility may be revised by Ethyl from time to time subject to concurrence by
Albemarle, which concurrence shall not be unreasonably withheld. Denial of
consent by Albemarle shall be only for the reason(s) set forth in (a) through
(d) in Section 8.04 below.

     8.03 (a) The finished MMT shall become the property of Ethyl upon the
loading of the MMT at the Orangeburg Plant on the transportation equipment of
the carrier delivering the MMT to Ethyl or Ethyl's customer. Except as otherwise
agreed by the parties, all risk of loss of MMT, Raw Materials and packaging
containers while under Albemarle's control shall remain with Albemarle
(regardless of who holds title to said items) until delivered to the carrier as
provided above. Albemarle shall bear the full responsibility of disposing of all
wastes generated from the MMT Facility.

     (b) Albemarle shall deliver MMT into transportation equipment for shipment
to Ethyl or its customers. Ethyl shall arrange for the availability of rail cars
and designate truck carriers to transport additives. Albemarle shall arrange for
required trucking services from Ethyl designated truck carriers. Albemarle shall
load at Ethyl's request MMT into designated rail cars,

                                      -8-

<PAGE>

tank trucks, portable equipment, ISO containers, intermediate bulk containers,
drums or other mutually agreed upon containers and provide such other ancillary
services to ship MMT such as palletizing, containerizing, unitized shipping,
documentation, container inspection, etc.

     (c) Albemarle agrees to furnish Ethyl with a monthly inventory statement of
MMT supplied to Ethyl pursuant to this Agreement indicating the inventory at the
start of the month, quantity of MMT produced during the month, quantity of MMT
shipped during the month, and inventory at the close of the month, as well as a
monthly report of corrective actions taken as a result of Ethyl complaints, and
such other information as may be reasonably requested by Ethyl's Coordinator.
Agreement with the inventory statement by the Coordinator shall be evidenced by
his written approval on a copy of the statement. Failure to reject the statement
and notify Albemarle of a discrepancy within thirty (30) days shall constitute
approval. If a disagreement arises between the parties on the inventory
statement, the parties shall use their reasonable efforts to resolve the
disagreement promptly.

     (d) Albemarle agrees to consider implementation of process or product
improvements requested by Ethyl, including, but not limited to, Ethyl's quality
improvement programs.

     8.04 If Ethyl desires to purchase a new methylcyclopentadienyl manganese
tricarbonyl product ("New MMT Product") from Albemarle, it shall so notify
Albemarle as far in advance of proposed manufacture as practicable but not less
than sixty (60) days prior to the date Ethyl wishes to begin such manufacture,
and Albemarle shall have the first opportunity and right of first refusal to
produce such New MMT Product pursuant to the procedure set forth below. For
purposes of this Agreement, a New MMT Product is one that is substantially
different in composition and/or formulation from any MMT Product described in
Exhibit A. Albemarle shall have the right to refuse to manufacture such New MMT
Product as provided below by giving Ethyl written notice of disapproval no later
than thirty (30) days after the date Ethyl notified

                                      -9-

<PAGE>

Albemarle of its desire to purchase such New MMT Product, provided, however,
that if written notice of refusal is not received by Ethyl within such thirty
(30) day period, Albemarle's approval shall be deemed as having been given.
Albemarle shall have the right to refuse only: a) if such manufacture would
cause Albemarle to use wastewater treatment services in excess of those services
used to manufacture MMT at the design capacity of the MMT Plant and add a
substantial burden to Albemarle's wastewater treatment plant; or b) if such
manufacture would cause a substantial adverse effect on Albemarle's other
Orangeburg Plant operations or facilities; or c) if such manufacture of such New
MMT Product would present an unreasonable health, safety or environmental hazard
or violate applicable laws or regulations; or d) if Albemarle, in its reasonable
judgment, is unable to manufacture the New MMT Product in a skillful manner and
Ethyl cannot supply the training or instruction to satisfy Albemarle training
needs. Notwithstanding anything to the contrary, however, such New MMT Product
will not be supplied pursuant to the terms of this Agreement and the pricing and
other terms for the supply of such New MMT Product shall be negotiated in good
faith by the parties. If the parties cannot agree on pricing and/or other terms
for the supply of such New MMT Product, Ethyl shall be permitted to have the New
MMT Product manufactured by a third party without further obligations under this
Agreement with respect to that New MMT Product provided the price and terms of
the purchase from a third party are not equal to or less favorable to Ethyl than
those offered by Albemarle. Notwithstanding any provision above to the contrary,
Ethyl may manufacture MMT or a New MMT Product at its own manufacturing
facilities as provided in Section 2.01 without obligation to Albemarle under
this Agreement.

     8.05 If Albemarle desires to manufacture or sell a New MMT Product (as
defined in Section 8.04) for use or consumption into Fuel Additive Products or
Lubricant Additive Products

                                      -10-

<PAGE>

(as defined in the MMT License Agreement), it shall so notify Ethyl (subject to
any confidentiality obligations which may be imposed on Albemarle) as far in
advance of proposed manufacture as practicable but not less than sixty (60) days
prior to the date Albemarle wishes to begin such manufacture. Ethyl shall have
the first opportunity to purchase such New MMT Product from Albemarle for use or
sale in Fuel Additive Products and Lubricant Additive Products, provided,
however, such New MMT Product will not be supplied pursuant to the terms of this
Agreement and the pricing and other terms for the supply of such New MMT Product
shall be negotiated in good faith by the parties and Ethyl shall not be
obligated to purchase such New MMT Product from Albemarle. Ethyl shall retain,
however, the right to receive most favored nations pricing on such New MMT
Product for similar quantities for use or sale in Fuel Additive Products and
Lubricant Additive Products in the geographical area where such New MMT Product
is sold. New MMT Products offered by Albemarle to Ethyl pursuant to this Section
8.05 shall not be considered New MMT Products for purposes of Section 8.04.

ARTICLE 9 - PRODUCTION ESTIMATES AND ORDERS.

     No later than fourteen (14) days before the first day of each calendar
quarter, Ethyl will submit to Albemarle a forecast of its requirements for MMT
for the next two calendar quarters. This estimate is for planning purposes only
and does not constitute an order to manufacture. Ethyl shall place product
orders for MMT with Albemarle on a mutually agreed upon schedule providing
sufficient time for Albemarle to manufacture and deliver the MMT order as
required by Ethyl. For purposes of this Agreement, lead times for placing orders
and for production of MMT shall be the same as those existing prior to the
Closing Date or such other times as are mutually agreed upon.

                                      -11-

<PAGE>

ARTICLE 10 - TRADEMARK LICENSE.

     Ethyl extends to Albemarle the right to apply Ethyl's or any of its
subsidiaries' trademarks to drums and other shipping receptacles used for MMT
produced for Ethyl under this Agreement and for that purpose solely.

ARTICLE 11 - BUDGETS.

     11.01 During the term of this Agreement, Albemarle shall prepare for
informational purposes a proposed capital budget for the MMT Facility in order
to perform its obligations under this Agreement for each calendar year or
portion thereof this Agreement is in effect and submit the same to Ethyl at
least ninety (90) days prior to the start of the period to which it applies.

     11.02 During the term of this Agreement, Albemarle shall prepare, on the
basis of Ethyl's forecasted sales, a proposed operating budget including planned
maintenance and turn-arounds for the MMT Facility for each calendar year or
portion thereof during the term of this Agreement and submit same to Ethyl at
least ninety (90) days prior to the start of the period to which it applies.

ARTICLE 12 - REIMBURSABLE COSTS.

     12.01 Except as otherwise provided herein, Ethyl shall reimburse Albemarle
monthly for all of the actual costs and expenses incurred by Albemarle,
including supplying the labor, equipment, Raw Materials, fuel and utilities,
required to operate the MMT Facility to supply MMT for Ethyl as required under
this Agreement ("Reimbursable Costs"); however, such costs and expenses shall
not include costs and expenses for which Albemarle is responsible pursuant to
this Agreement, or MMT Related Claims. Depreciation or amortization expense on
(i) capital expenditures for facilities owned by Ethyl or (ii) capital
expenditures which were reimbursed by Ethyl to Albemarle or (iii) facilities in
place at the MMT Facility as of the Closing Date shall not

                                      -12-

<PAGE>

be considered a Reimbursable Cost under this Agreement. The method of
calculating Reimbursable Costs shall be the accounting policies, procedures and
cost-allocation practices used by Ethyl for the Orangeburg Plant for the 1993
calendar year ("Plant Cost System"). The references to labor, equipment, Raw
Materials, fuel and utilities above shall not be construed to limit the
application of the Plant Cost System, but is for illustrative purposes only.
Albemarle shall promptly notify Ethyl of any and all updates, revisions and/or
interpretations of said policies, procedures and cost-allocation practices if
such a change will cause a material adverse change in the computation of costs
reimbursable by Ethyl to Albemarle under this Agreement. Any such change in
computation of costs reimbursable by Ethyl to Albemarle shall require the
consent of Ethyl prior to implementation. The parties agree to negotiate in good
faith changes in the method of computing costs reimbursable by Ethyl where it is
demonstrated that substantial inequities will result in using the Plant Cost
System.

     12.02 Ethyl shall not be responsible to reimburse Albemarle, for costs of
manufacture, rework or disposal of product prior to shipment to Ethyl or its
customers which fails to meet Ethyl's product specifications set forth in
Exhibit A, as amended, which is in excess of the percentage of the total
off-specification MMT produced at the Orangeburg Plant in relation to the total
MMT meeting specifications produced at the Orangeburg Plant for the calendar
years 1992 and 1993. It is agreed between the parties that Albemarle shall have
no responsibility for MMT returned or rejected by customers for failure to meet
Ethyl specifications if the product sample retained by Albemarle, when tested in
accordance with mutually agreed upon test procedures, establishes the product
met the MMT specifications set forth in Exhibit A, as amended, when loaded for
delivery to Ethyl or its customers.

          Copy to:

          Ethyl's Coordinator

     12.04 Albemarle shall maintain for a period of five (5) years from the date
of preparation good and sufficient records in accordance with generally accepted
accounting principles consistently applied to support the costs and expenses
invoiced hereunder and such other records as Ethyl may reasonably request. All
records relating to the equipment, Raw Material, labor, fuel and utilities,
including all inventory balances relating to the MMT Facility maintained by
Albemarle and all accounting, policies, procedures and cost-allocation practices
employed by Albemarle shall be available for audit by Ethyl's representative
during normal hours of business, provided that not more than two (2) such audits
shall be held during any calendar year. In the event an audit determines that an
overcharge or undercharge has occurred, Albemarle or Ethyl, as the case may be,
shall promptly credit the amount of such overcharge or undercharge to the proper
party's account. If the audit reveals an overcharge in excess of three percent
(3%) for the period being audited (which shall in no event be less than one (1)
calendar

                                      -14-

<PAGE>

quarter) Albemarle shall in addition to any credit required above reimburse
Ethyl for its audit costs.

     12.05 In the event there is a disagreement between the parties on any item
or items included in an invoice of which Ethyl has informed Albemarle in writing
within thirty (30) days from receipt of invoice, or as revealed in an audit
report as provided for in Section 12-04, Ethyl shall promptly pay the portion of
the invoice not in dispute and the parties shall meet and in good faith use
their reasonable efforts to resolve the disagreement as promptly as possible and
prior to the issuance of the next invoice. If Ethyl and Albemarle cannot resolve
their disagreement within sixty (60) days from date of receipt of invoice or
audit report said matter shall be referred to a mutually agreeable national
accounting firm ("Dispute Arbitrator") for resolution. The decision of the
Dispute Arbitrator shall be binding on both parties. The fees and costs of the
Dispute Arbitrator shall be allocated to the parties as determined by the
Dispute Arbitrator.

ARTICLE 13 - OPERATING FEE.

     In addition to the Reimbursable Costs to be paid by Ethyl under Article 13,
Ethyl shall lay to Albemarle during the term of this Agreement a monthly
Operating Fee of [REDACTED] percent ([REDACTED] %) of all Reimbursable Costs
excluding the cost of all Raw Materials used to produce MMT whether or not
directly purchased by Ethyl and capital expenditures reimbursed to Albemarle by
Ethyl pursuant to the Agreement.

ARTICLE 14 - ENVIRONMENTAL, HEALTH AND SAFETY MATTERS.

     14.01 It is understood and agreed that Albemarle and not Ethyl is solely
responsible for the operation of the MMT Facility, and Albemarle will not look
to Ethyl for indemnification or reimbursement for liabilities or fines and the
costs or expenses associated with defending such matters relating to health,
safety or environmental concerns arising out of such operation by Albemarle. In
performing its obligations under this Agreement, Albemarle will comply with

                                      -15-

<PAGE>

applicable governmental, health, safety and environmental laws, regulations,
permits, orders and decrees, relating to the operation of the MMT Facility and
the disposal of any and all waste products.

     14.02 Albemarle will continue in effect, or obtain, or cause to be obtained
and maintained, all governmental licenses and permits necessary for the
operation of the MMT Facility to supply MMT as required by this Agreement and to
monitor compliance with applicable local, state or federal regulations as
required, and to maintain such records as may be required thereunder and to
fulfill all, reporting requirements thereunder.

     14.03 If during the term of this Agreement the MMT Facility becomes in
violation of any laws or regulations, including any environmental laws,
regulations, ordinances, permits, orders or decrees, and as a result Albemarle
is required under law to cease or suspend the operation of the MMT Facility,
Albemarle shall have the right to so cease or suspend such operation without
liability until the violation or noncompliance is corrected or until it is
legally permitted to continue such operations provided such violation was not
due to the gross negligence or intentional misconduct of Albemarle. Ethyl shall
have no obligation under Article 12 and 13 of this Agreement to compensate
Albemarle during this period that Albemarle is unable to meet Ethyl's
requirements. Should Albemarle's operations be only partially curtailed, Ethyl
shall continue to purchase MMT that can be produced. However, if Ethyl's
requirements not be met by Albemarle, Ethyl shall be free to purchase MMT
elsewhere until production is restored.

     14.04 Albemarle agrees to keep Ethyl informed of any discussions or
negotiations with any governmental body which is likely to materially affect the
MMT Facility. Additionally,

                                      -16-

<PAGE>

Ethyl reserves the right to conduct, join or participate in any legal
proceedings, administrative, civil or criminal directly pertaining to the
operation of the MMT Facility.

     14.05 Albemarle, shall be responsible for fines and penalties attributable
to the operation by Albemarle of the MMT Facility (including attorney's fees and
consulting fees to defend against such Claims) and such costs shall not be
reimbursed by Ethyl under this Agreement.

ARTICLE 15 - LIABILITY.

     With respect to MMT, a party's liability to the other party for Claims
alleged against said party for damaged or defective MMT, failure to produce MMT,
loss of MMT or off specification MMT shall be limited to damages arising
directly from contractual breach, breach of warranty, strict liability or
tortious conduct (including negligence) of the other, but subject to the
following limitations:

     (i) Each individual claim filed with the other party must exceed
     $[REDACTED], unless the total amount of damages for all Claims, whether or
     not filed with the other party, exceeds $[REDACTED] in a contract year
     (such contract year(s) beginning on the Closing Date (and each anniversary
     thereafter)), in which event the $[REDACTED] threshold for filing a claim
     will no longer be applicable.

     (ii) In no event shall the obligation of either party to the other party
     relating to Claims under this subsection (b) not reimbursed by insurance
     proceeds exceed [REDACTED] Dollars ($[REDACTED]) in any contract year.

     (iii) Neither party shall be liable to the other for lost profits and/or
     consequential damages resulting from such Claims.

                                      -17-

<PAGE>

     It is understood and agreed that Ethyl and not Albemarle is responsible for
the introduction of MMT sold to Ethyl into the stream of commerce, and Ethyl
accepts responsibility for claims by third parties to the extent such claims are
not due to the MMT not meeting specification.

The above limitations do not apply to intentional breaches of contract, reckless
disregard of contract, reckless disregard of a party's obligation as a prudent
operator or intentional tortious conduct.

ARTICLE 16 - SECRECY.

     16.01 Except as otherwise provided in the MMT License Agreement between
Ethyl and Albemarle, Albemarle agrees to hold in confidence for a period of ten
(10) years from the date of disclosure or five (5) years from termination or
expiration of this Agreement, whichever is later, all information relating to
Ethyl's operations, including but not limited to all processes, formulas and
other information and data, equipment, methods of operation, Raw Materials,
sales and marketing information and products of which it had knowledge prior to
the Closing Date or which it becomes aware as a result of the activities of its
employees, agents and representatives at the MMT Facility or Albemarle's
Orangeburg Plant, and Albemarle further agrees that it will not use for any
reason or disclose to others any or all of such information except to the extent
necessary to perform its obligations under this Agreement, and then only after
receiving the written permission of Ethyl's Coordinator and under agreements to
hold such information secret and confidential at least to the same extent that
Albemarle is bound under this Agreement.

     16.02 The provisions of Section 16.01 shall not apply to any information
that either before or after the time of its disclosure to Albemarle is or
becomes public knowledge through no fault of Albemarle; or that Albemarle
receives after the Closing Date from a third party who owes no obligation of
confidence with respect thereto to Ethyl.

                                      -18-

<PAGE>

     16.03 Except as otherwise provided in the MMT License Agreement between

this Agreement, whichever is later, and not use for any reason or disclose to
others all information relating to Albemarle's operations at Orangeburg Plant,
including the equipment, methods of operation, processes, raw materials, sales
and marketing information and products of which it had knowledge prior to the
Closing Date or which it becomes aware as a result of the activities of its
employees, agents and representatives at Albemarle's Orangeburg Plant.

     16.04 The provision of Section 16.03 shall not apply to any information
that either before or after the time of its disclosure to Ethyl is or becomes
public knowledge through no fault of Ethyl, or that Ethyl receives from a third
party who owes no obligation of confidence with respect thereto to Albemarle.

ARTICLE 17 - FORCE MAJEURE.

     Neither Albemarle nor Ethyl shall be liable for any failure or delay in its
performance hereunder when such failure or delay is caused, directly or
indirectly, by fires; floods; storms; earthquakes; tidal waves; accidents;
explosion; sabotage; strikes or other labor disturbances (regardless of the
reasonableness of the demands of labor); national emergencies; civil commotions;
riots; invasions; wars; military operations; acts; restraints, requisitions,
regulations, prorations, orders of government, or any officer, department,
agency authority, instrumentality or committee thereof; shortages of labor,
fuel, power or Raw Materials-plant breakdowns; inability to obtain supplies, or
failures of normal sources of supplies; inability to obtain or delays of
transportation facilities; any act of God-or any cause (whether similar or
dissimilar to the foregoing) beyond the reasonable control of Albemarle or
Ethyl, as the case may be. If any of the events in this Article 17 shall have
occurred, the party affected shall promptly notify the

                                      -19-

<PAGE>

other party in writing of the occurrence of such event and the extent and
potential duration of such interruption. Nothing herein shall be construed to
require Albemarle or Ethyl to submit to any demand of labor or labor unions
which it considers unreasonable. The cause of the failure or delay shall be
remedied to the extent reasonably possible without undue delay, and performance
shall be resumed at the earliest practical time after cessation of such
interruption. Ethyl shall have no responsibility to Albemarle under Article 12
and 13 of this Agreement to the extent and for the period of any event of force
majeure invoked by Albemarle.

ARTICLE 18 - TRANSFERS AND ASSIGNABILITY.

     18.01 This Agreement shall be binding upon and shall inure to the benefit
of the parties and their respective successors and permitted assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement. The rights and obligations of the parties under this Agreement may
not be assigned or delegated except as set forth in this Article 18. It is
agreed that either party may assign its rights and/or delegate its obligations
under this Agreement to an affiliate of the assigning party, provided that the
assigning party shall not be released from its obligations hereunder. It is
further agreed that rights and/or obligations under this Agreement may be
assigned: (i) by Ethyl or Albemarle to another party in connection with its
merger into or sale of substantially all of its assets to such other party; or
(ii) by Ethyl to another party in connection with the sale or other disposition
of substantially all of the business or assets relating to MMT; or (iii) by
Albemarle to another party in connection with the sale or other disposition of
substantially all of Albemarle's Orangeburg Plant, provided such other party
expressly agrees in writing to assume the obligations set forth herein, and
neither Ethyl nor Albemarle, as the case may be, shall thereby be released
therefrom.

     18.02 If during, the term of this Agreement, there is a change in control
of either party or this Agreement is transferred or assigned to another party,
the party undergoing the change of

                                      -20-

<PAGE>

control or initiating an assignment or transfer shall promptly notify in writing
the other party of such anticipated change of control or assignment or transfer,
which notice shall be prior to such event, if possible. Upon such notice, the
other parry may require further written contractual assurances in addition to
this Agreement that the operation of the MMT Facility and the supply of MMT to
Ethyl or the purchase of MMT from Albemarle shall continue without interruption
for the term of this Agreement. In the case of assignment or transfer, failure
to provide such written contractual assurances shall permit the party so
affected to withhold its consent to any such transfer or assignment. In the case
of change of control, failure to provide such contractual assurances within
sixty (60) days from the date of change of control shall constitute a breach of
this Agreement.

     18.03 No provision of this Agreement may be amended, modified or waived
except by written agreement duly executed by an authorized officer of each of
the parties.

ARTICLE 19 - PATENT AND TRADEMARK INFRINGEMENT.

          matter including the defenses, compromise or settlement of such a
          Claim-

          allegedly infringing MMT to meet the specifications as required by
          this Agreement;

     (d)  Albemarle fully cooperates with Ethyl in resolving the Claim.

     19.02 Albemarle agrees to indemnify, defend and hold Ethyl harmless from

ARTICLE 20 - DISPUTE RESOLUTION.

     Any dispute arising hereunder, except for those described in Article 12
hereof, shall be settled and determined by arbitration under the then-current
Commercial Arbitration rules of the American Arbitration Association, by a panel
of three (3) arbitrators, with such arbitration to be held in Richmond,
Virginia. The costs and expenses of the arbitration shall be shared as
determined by the arbitration panel. The decision and award of the panel shall
be final and binding and the award so rendered may be entered in any court
having jurisdiction thereof.

ARTICLE 21 - MISCELLANEOUS.

     21.01 No other terms or conditions, other than those stated herein, and no
agreement or understanding (including purchase orders and order acknowledgments
of the parties) in any way modifying the terms and conditions herein stated,

Reorganization Agreement and this Agreement conflict, this Agreement shall
prevail.

                                      -22-

<PAGE>

     21.02 In the event any provision of this Agreement is declared
unenforceable by a recognized court of law, then this Agreement with respect to
the rights and remedies accrued under the remaining enforceable provisions shall
survive any such declaration; provided that this Agreement continues to express
the intent of the parties. In the event the intent of the parties cannot be
preserved, the parties shall use their reasonable efforts to negotiate new terms
for the purchase and sale of MMT. If agreement cannot be reached, the parties
will submit the issue to binding arbitration as provided in Article 20.

     21.03 Any failure of either party at any time or from time to time to
enforce or require the strict keeping and performance by the other party of all
or any of the terms and conditions of this Agreement shall not constitute a
waiver by that party of a breach of any such terms or conditions in any way, or
the right of that party at any time to avail itself of any remedies it may have
against the other party for any such breach or breaches of such terms or
conditions.
