 AMENDED AND RESTATED 
 PURIFIED WET
PHOSPHORIC ACID SUPPLY AGREEMENT 
  
 This Agreement made this
23rd day of March, 2000, by and between Rhodia Inc., a Delaware corporation (“Rhodia”), and PCS Purified Phosphates, a Virginia general partnership formerly known as Albright & Wilson Company (“Partnership”).

  
 W I T N E S S E T H: 
  
 WHEREAS, on July 29, 1988, Albright & Wilson Americas Division of Tenneco
Canada, Inc., an Ontario corporation (“A&W Canada”), and Partnership entered into a Purified Wet Phosphoric Acid Supply Agreement dated of even date (as amended from time to time since that date, the “1988
Agreement”); and 
  
 WHEREAS, Albright & Wilson
Americas Limited, a Canadian corporation (“A&W Ltd.”), is a successor to A&W Canada under the 1988 Agreement and, thus, A&W Ltd. and Partnership are parties to the 1988 Agreement; and 
  
 WHEREAS, PCS Phosphate Company, Inc., a Delaware corporation, formerly known
as Texasgulf Inc. (“PCSP”), Albright & Wilson Americas, Inc., an affiliate of A&W Ltd. (“A&W Inc.”), Partnership, and PCS Industrial Products, Inc., a Delaware corporation (“PCSA”), and
Rhodia, have entered into a Distribution and Sale Agreement, dated as of March 23, 2000 (the “Distribution and Sale Agreement”), pursuant to which, among other things, Partnership has agreed to distribute certain assets of
Partnership to A&W Inc. and A&W Inc. has agreed to sell its entire interest in Partnership to PCSP as provided therein; and 
  
 WHEREAS, in connection with the transactions contemplated by the Distribution and Sale Agreement and in order to satisfy a condition to the obligations of
Partnership under the Distribution and Sale Agreement, Rhodia and Partnership desire to enter into this Agreement to effect various further amendments to, and to restate, the 1988 Agreement, and to designate Rhodia as the purchaser thereunder.

  
 NOW, THEREFORE, for and in consideration of the premises and
the mutual covenants herein set forth, Rhodia and Partnership hereby amend and restate the 1988 Agreement in its entirety and agree as follows: 
  
 1. Purchase and Sale; Specifications. 
  
 1.1 Partnership shall sell and deliver, and Rhodia shall purchase and receive, during the term hereof, low alkali purified wet phosphoric
acid (“Low Alkali Product”), low alkali low sulfate purified wet phosphoric acid (“Low Sulfate Product”) and high alkali purified wet phosphoric acid (“High Alkali Product”; each of Low Alkali
Product, Low Sulfate Product 

 
and High Alkali Product sometimes referred to herein as a “Product”, and, collectively, the “Products”) in the quantities and subject to
the terms and conditions hereinafter set forth. 
  
 1.2 Except as set forth in Section 1.3 hereof, the Products shall conform with the specifications described in Exhibit A attached hereto. Partnership’s analyses at point of transfer shall govern unless shown to be in error. A list of
Partnership’s analytical procedures used for Products is attached hereto as Exhibit B. Partnership shall obtain analyses of all Products transferred and shall provide Rhodia a Certificate of Analysis with each transfer of the Products. In the
event that Low Alkali Product or Low Sulfate Product shall not conform with any new Food Chemicals Codex standard, then upon sixty (60) days advance written notice to Partnership, Rhodia may elect to reduce or temporarily eliminate shipment and
minimum purchases of the affected Products or any portions thereof under this Agreement, such notice indicating (i) the date on which any change in shipment and/or purchases shall occur and (ii) the volume of the applicable affected Product which
Rhodia elects to purchase, until such time as the Partnership again offers products hereunder conforming with such standards. If Partnership subsequently notifies Rhodia that the affected Products then meet the minimum applicable Food Chemicals
Codex standards and that no change in Product pricing is required hereunder, within sixty (60) days of such notice, Rhodia shall renew its purchase of Products at those then applicable levels set forth in Exhibit C. If Partnership advises Rhodia
that an increased price for Products will be required to compensate Partnership for capital expenditures or increased operating costs, the parties shall negotiate in good faith as to such new prices and volumes for Product. If no agreement is
reached within nine (9) months of Partnership’s notice, either party shall have the right to terminate this Agreement as to the affected volumes of Low Alkali Product and/or Low Sulfate Product upon not less than six (6) months notice. Except
to the extent Rhodia declines to purchase Improved Products as set forth in Section 1.3 below, each type of Product sold hereunder shall be of Partnership’s typical quality. 
  
 1.3 The parties recognize that Partnership may develop materials from time to time that are capable of being
substituted for one or more of the Products. In the event that Partnership develops any such materials and constructs or modifies facilities so as to be capable of manufacturing such materials, then Partnership shall provide Rhodia with a written
notice of (i) the specifications for such materials and (ii) the Food Chemicals Codex applicable to such materials (in each such case, such grade of material is referred to hereinafter as the “Improved Product”). Within three (3)
months following receipt of any such notice from Partnership, Rhodia shall notify Partnership in writing as to whether Rhodia intends to purchase Improved Product in substitution for a particular type of Product. The parties agree to negotiate with
one another in good faith to determine the amount of an adjustment, if any, to be made to the pricing terms hereunder, the volume of the Improved Product to be purchased and any other provisions of this Agreement that shall be modified. In the event
that the parties are unable to reach agreement regarding a mutually acceptable amendment to this Agreement concerning such Improved Product within six (6) months following the date that Partnership notified Rhodia under this Section 1.3, neither
party shall thereafter have any obligation hereunder to purchase or supply the applicable Improved Product. 
  

 2 

 2. Term. The term of this Agreement shall be for the period commencing on the date of this
Agreement and ending on July 29, (****) (the “Initial Term”), and thereafter shall be extended without further action of the parties for additional terms of (****) years (each an “Additional Term”) upon the
expiration of the Initial Term or any Additional Term; provided, however, that upon not less than twenty-four (24) months’ prior written notice to the other party hereto, either party may cause this Agreement to terminate upon the
expiration of the Initial Term or any Additional Term thereafter. 
  
 3. Price and Terms. 
  
 3.1
Rhodia shall pay to Partnership in U.S. Dollars a price per short ton (“st”) of P2O5 contained in Product F.O.B. at the Aurora Plant determined as follows: 
  

	 	(i)	The initial price for Low Alkali Product is $(****); 

  

	 	(ii)	The initial price for Low Sulfate Product is $(****); and 

  

	 	(iii)	The initial price for High Alkali Product is $(****). 

  
 The price for each of the Low Alkali Product, Low Sulfate Product and High Alkali Product shall be adjusted during the term of this Agreement in accordance with the
provisions set forth on Exhibit C attached hereto. 
  
 As used
herein, “Contract Year” means a calendar year commencing January 1 during the term of this Agreement, except that the first such period shall commence upon the date of this Agreement and terminate on December 31, 2000. As used
herein “Contract Quarter” means a period of three (3) consecutive months, beginning January 1, April 1, July 1, or October 1, except that the first such period shall commence upon the date of this Agreement and end on the day prior
to the start of the first full Contract Quarter. 
  
 3.2 On or before the September 30th prior to the commencement of each Contract Year (as defined in Section 3.1), Partnership shall give Rhodia written notice of its estimate of the price for each Product for such Contract Year. On or prior
to June 30 of the next following Contract Year, Partnership shall determine the actual price for each Product purchased, and to be purchased by Rhodia during such Contract Year (based upon the calculations set forth in Exhibit C) and shall invoice
or credit Rhodia for the difference, if any, between such actual price and the amount previously invoiced at the estimated prices to Rhodia for such Contract Year. For the remainder of such Contract Year, Partnership shall invoice Rhodia for the
actual price for the Products as so determined. 
  
 3.3 Partnership shall invoice Rhodia for payment with respect to each shipment of Product hereunder, and the terms of payment for all Products purchased hereunder shall be net thirty (30) calendar days from date of the invoice. 

 

 3 

 3.4 Partnership shall keep and maintain true and accurate records as may be necessary to
verify volumes delivered and indices tracked as bases for prices charged to Rhodia under this Agreement. If Rhodia disputes any of the amounts charged hereunder, Partnership shall allow representatives of Rhodia immediate and full access (including
the rights of physical inspection and to make copies) to such records and such other information maintained by Partnership as may be necessary for the verification of such amounts. Partnership and Rhodia shall use their best efforts to resolve such
dispute within 45 calendar days after the relevant invoice date. 
  
 3.5 If it is determined that there has been an overcharge, then Partnership shall immediately refund the overcharge received by it to Rhodia or, if such amount has not been previously paid, Rhodia shall pay to
Partnership the correct amount owed to Partnership. If it is determined that there has been an undercharge, Rhodia shall immediately pay the undercharge to Partnership plus any additional amounts not previously paid hereunder. 
  
 3.6 Notwithstanding anything to the contrary contained in
this Section 3, with respect to any Contract Year after the (****) Contract Year hereunder, if Rhodia notifies Partnership of a bona fide opportunity, and provides a copy thereof in writing (showing all terms of the offer, including the offering
party), under which Rhodia is to purchase a quantity of phosphoric acid of a quality equal to or better than a specific Product manufactured by Partnership at a price F.O.B. rail car customs cleared U.S. East Coast port that, giving effect to all
conditions of such offer, is at least ten percent (10%) less than the price per short ton then in effect under this Agreement for the relevant Product (the “Lower Offer”), Partnership shall have the option to meet the Lower Offer
within fifteen (15) calendar days after notification by Rhodia, for the same annual quantity as that to which the Lower Offer relates. In the event that Partnership does not elect to meet the Lower Offer, then (i) Rhodia shall be released from its
obligation hereunder to purchase the annual volume of the Lower Offer up to an amount equal to the lesser of (a) (****) short tons of the Product or (b) (****) short tons of the Product minus the sum of all then effective Released Quantities
and Met Quantities (both as hereinafter defined), and (ii) the portion of each type of Product required to be purchased by Rhodia as set forth in Exhibit C shall be proportionately reduced to equal the result of multiplying the annual amount of such
Product which Rhodia is required to purchase as set forth in Exhibit C times a fraction, the numerator of which is the total annual number of short tons of all Product required to be purchased as set forth in Exhibit C minus the Released Quantity
and the denominator of which is (****). “Released Quantity” means the annual quantity of short tons of Product that Rhodia has been released from its obligation to purchase hereunder pursuant to a Lower Offer presented to
Partnership by Rhodia in accordance with this Section, “Met Quantity” means the annual quantity of short tons of Product for which Partnership has reduced the purchase price hereunder pursuant to a Lower Offer presented to
Partnership by Rhodia in accordance with this Section. With respect to all Released Quantities hereunder, such right to purchase from such third party must be exercised in writing by Rhodia within sixty (60) calendar days and shall be effective
twelve (12) months after Partnership’s receipt of Rhodia’s notice of the Lower Offer in accordance with the notice provisions set forth herein. In the event that Rhodia shall accept any Lower Offer from such third party pursuant to the
terms hereof, then, upon the expiration of the contract or other arrangement entered into pursuant to such Lower Offer, Rhodia shall revert to 

  

 4 

 
the purchase of quantities of Product from Partnership, at the then effective price hereunder, which Rhodia was required to purchase prior to application of
this Section. In the event that Partnership elects to meet the Lower Offer, then (i) Partnership shall sell to Rhodia on an annual basis the quantity of Product as to that which the Lower Offer relates, up to an annual amount equal to the lesser of
(a) (****) short tons of the Product or (b) (****) short tons of the Product minus the sum of all then effective Released Quantities and Met Quantities at the price per short ton in the applicable Lower Offer (the “Met
Price”) for the term specified in the Lower Offer (the “Met Term”), and (ii) the Met Price shall remain in effect with respect to the Met Quantity for the entirety of the Met Term despite any subsequent Lower Offer received
by Rhodia that contains a price per short ton less than the Met Price. Upon the expiration of the applicable Met Term, Rhodia shall revert to the purchase of Product from Partnership at such price that Rhodia was required to pay prior to adjustment
under this Section. Rhodia shall be entitled to present subsequent Lower Offers to Partnership under this Section so long as, at the time of any such subsequent Lower Offer, the sum of all effective Released Quantities and Met Quantities does not
exceed (****) short tons of Product on an annual basis. 
  
 4.
Quantity. 
  
 4.1 For each Contract Year,
Partnership shall sell and ship to Rhodia, and Rhodia shall purchase from Partnership, Low Alkali Product, Low Sulfate Product and High Alkali Product ordered by Rhodia subject to the parameters set forth in Exhibit C (except as otherwise agreed by
the parties in writing). In the event that Rhodia does not purchase the applicable required minimum volume of High Alkali Product during any Contract Year and Partnership recycles High Alkali Product, Rhodia shall pay a “Recycle Fee” for
all such tons of High Alkali Product so recycled equal to the difference between the applicable minimum volume on High Alkali Product and the actual amount of High Alkali Product purchased by Rhodia during such Contract Year. The Recycle Fee for
Contract Year 2000 is $(****) per short ton of P2O5. The Recycle Fee for Contract Years after 2000 shall be the product of (i) $(****) and (ii) a fraction in which (a) the price per short ton P2O5 of High Alkali Product for the applicable Contract Year, calculated in accordance with this Agreement, is the numerator and (b) $(****) per short ton P2O5 is the denominator.

  
 4.2 If, at any time during the term of this
Agreement, Rhodia reasonably determines that it is not in Rhodia’s economic interest to continue to purchase the Low Alkali Product, Low Sulfate Product or High Alkali Product, due to events or circumstances outside of Rhodia’s control
(including, but not limited to, customer demand, market pricing conditions and government regulations (other than government regulations that would excuse Rhodia’s delay in performance or non-performance of any of the terms and conditions of
this Agreement in accordance with Section 8 hereof)), which eliminate Rhodia’s earnings (before interest and taxes as determined in accordance with United States generally accepted accounting principles) on any Products purchased from
Partnership or any products incorporating such Products for a consecutive eighteen-month (18-month) period (such determinations constituting a declaration by Rhodia of “economic force majeure”); then Rhodia shall notify Partnership
in writing of such determinations and, beginning on the date of Rhodia’s notice (the “EFM Notice Date”) and ending no later than six (6) months from the EFM Notice Date, the parties will discuss and 

  

 5 

 
evaluate in good faith, proposals to address such economic force majeure in a manner that (i) does not obligate Partnership to suffer any adverse financial
or operational consequences therefrom and (ii) provides Rhodia with some relief from the financial consequences thereof. Upon expiration of such period, Partnership, in the exercise of its sole discretion and upon written notice to Rhodia, will
select a proposal to address such economic force majeure should it continue, which approach shall be implemented on or before eighteen (18) months from the EFM Notice Date, provided that Rhodia has the right to reject any approach selected by
Partnership and to continue to operate under the terms of this Agreement. 
  
 5. Order Procedure; Delivery. 
  
 5.1 On or before the September 15th prior to the commencement of each Contract Year,
Rhodia shall give Partnership written notice of its estimate of the quantity of each Product to be supplied by Partnership hereunder during such Contract Year. Except as otherwise provided in Section 4 above, nothing herein shall require Rhodia to
purchase quantities of Product equal to the annual estimate. Seven (7) business days prior to the first day of each month, Rhodia shall provide Partnership with a three-month projection of its quantity requirements hereunder. The quantities
specified for the first month of such three-month projection shall be binding upon Rhodia; however, the amounts specified for the remaining two (2) months shall be estimates only and shall not bind Rhodia. 
  
 5.2 Rhodia shall issue purchase instructions from time to
time for its requirements of Products not less than two (2) days prior to its intended shipment date. Partnership shall use commercially reasonable efforts to fulfill each order on the shipment date set forth therein. Shipments for each Contract
Quarter shall be scheduled in reasonably equivalent monthly volumes, with variations for any month not exceeding plus or minus 20% of one-twelfth (1/12th) of the proposed annual volumes to be purchased hereunder (i.e. the annual volume of each Product noticed pursuant to Section 5.1 above) unless otherwise mutually agreed to by the parties. 

 
 5.3 Partnership shall, at Rhodia’s sole cost,
arrange delivery of Products purchased hereunder from the Aurora Plant to the relevant delivery point specified by Rhodia. Delivery shall be via rail cars or tank trucks made available by Rhodia. Rhodia shall reimburse Partnership each month for all
costs incurred by Partnership under this Section 5.3, including all actual duties and the costs of insurance and of providing, maintaining and loading such tank cars or tank trucks, as the case may be, after the Products leave the Aurora Plant.

  
 6. Title and Risk of Loss. Title, and risk of loss or
damage, to Products shall pass to Rhodia at such time as Products are pumped into rail tank cars or tank trucks, as the case may be, at the Aurora Plant. 
  
 7. Limited Warranty; Indemnification. 
  
 7.1 Partnership warrants title and that the Products shall conform to the specifications set forth on Exhibit A attached hereto. Subject
to the preceding sentence and 

  

 6 

 
except as otherwise expressly provided herein, PARTNERSHIP MAKES NO REPRESENTATION OR WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, BY OPERATION OF LAW OR
OTHERWISE, AS TO MERCHANTABILITY, FITNESS FOR PARTICULAR PURPOSE, OR ANY OTHER MATTER WITH RESPECT TO THE PRODUCTS, WHETHER USED ALONE OR IN COMBINATION WITH ANY OTHER MATERIAL. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR
INCIDENTAL, SPECIAL, PUNITIVE OR CONSEQUENTIAL DAMAGES RESULTING FROM A DELAY OR FAILURE OF PERFORMANCE OR ANY OTHER DEFAULT HEREUNDER EXCEPT FOR ANY DAMAGE ARISING OUT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE LIABLE PARTY. 

 
 7.2 Rhodia may reject Products not conforming to the
corresponding specifications set forth on Exhibit A attached hereto by delivering notice to Partnership within 75 calendar days of the delivery of such Products to Rhodia. Failure to give notice within 75 calendar days after receipt by Rhodia of
Products shall constitute acceptance of such Products. Partnership shall have the right to inspect the Products so rejected for the purpose of confirming their nonconformance to the corresponding specifications set forth on Exhibit A attached
hereto. If Rhodia and Partnership agree that such Products conform to the corresponding specifications set forth on Exhibit A attached hereto, Rhodia shall revoke its rejection of, and shall accept, such Products. If Rhodia and Partnership are
unable to agree as to whether such Products are nonconforming or not, they shall select an independent laboratory to analyze the Products, whose determination shall be conclusive. All analyses conducted pursuant to this Section shall be conducted in
accordance with the analysis procedures listed on Exhibit B attached hereto. 
  
 7.3 If (i) Products delivered to Rhodia fail to meet the corresponding specifications set forth on Exhibit A attached hereto, (ii) Rhodia notifies Partnership of such nonconformance within 60 calendar days of delivery
and (iii) Rhodia nevertheless accepts such Products, then Rhodia and Partnership shall negotiate in good faith to adjust the price to be paid by Rhodia for such Products. 
  
 8. Force Majeure. Partnership and Rhodia shall each be excused for any delay in performance or for non-performance of
any of the terms and conditions of this Agreement, other than payment of money, caused by any cause or circumstance beyond their respective control including, but not limited to, any act of God, fire, flood, or governmental regulations, governmental
directive (including, without limitation, any governmental regulation, directive that prevents Rhodia’s customers from consuming Products or materials manufactured by Rhodia using the Products or selling products made therefrom), accident,
strikes, lockouts or unavoidable breakdowns, for the duration and to the extent that any such cause or circumstance affects the production, delivery, acceptance, transportation or consumption of Products hereunder. Each party hereto agrees to give
the other party notice, as early as reasonably possible, of any cause or circumstance which might give rise to a delay, interruption or reduction on any delivery or acceptance of Products hereunder, so that the other party might make appropriate
other arrangements. In the event Partnership is unable to supply the full quantities of Products required hereunder due to such cause or circumstance, Partnership shall, in allocating 

  

 7 

 
available supplies of Products, accord Rhodia parity with respect to the requirements of Partnership, Partnership’s affiliated companies, and
Partnership’s other customers. 
  
 In the event that
Partnership is excused from performance hereunder in accordance with this Section 8, for so long as such nonperformance continues, Rhodia shall be allowed to purchase phosphoric acid from third-party manufacturers in an amount equal to the volume
unfulfilled by Partnership. 
  
 After cessation of the effects of
a cause or circumstance as described above, Partnership shall not be required to make up, nor shall Rhodia be required to accept, any deliveries or quantities of Products the supply of which had been excused as a result of such cause or circumstance
pursuant to the provisions of this Section. 
  
 9. Taxes.
The price specified herein does not include any sales, excise, customs or similar tax, charge, duty or cost levied or imposed as of this date by any federal, state, municipal or other governmental authority upon the manufacture, sale, delivery,
shipment or use of Products sold hereunder, and any such tax, charge or cost, as well as any increases therein or any similar taxes or charges levied after the date of this Agreement shall be for the account of Rhodia. Income, franchise, gross
receipts, excess profit, and other similar taxes are not to be regarded as taxes, charges or costs within the meaning of this paragraph. 
  
 10. Miscellaneous. 
  
 10.1 Neither party shall (by operation of law or otherwise) assign or transfer its rights or delegate its performance hereunder without
the prior written consent of the other, which consent shall not unreasonably be withheld, and any attempted assignment, transfer or delegation without such consent shall be void. 
  
 10.2 Any notice required or permitted to be given hereunder shall be in writing (including facsimile
transmission) and shall be deemed to have been given when delivered in person or by courier or received by facsimile or seven (7) calendar days after mailing by registered or certified mail to the following addresses:

 AMENDED AND RESTATED 
 ACID
PURCHASE AGREEMENT AMONG 
 RHODIA, INC., PCS SALES (USA), INC. AND 
 PCS NITROGEN FERTILIZER L.P. 
  
 THIS AGREEMENT, dated this 23rd day of March, 2000 (the “Effective Date”), among Rhodia Inc., a Delaware corporation (“Rhodia”), PCS Sales
(USA), Inc., a Delaware corporation (“PCS”), and PCS Nitrogen Fertilizer, L.P., a Delaware limited partnership (“PCSN”) amends and restates the Acid Purchase Agreement dated as of May 2, 1989 (the “Original
Agreement”) between Stauffer Chemical Company Division of Rhöne-Poulenc Inc., Rhodia’s predecessor and Arcadian Corporation, predecessor to PCS and PCSN. 
  
 Introduction. 
  
 Rhodia owns and operates a phosphoric acid extraction facility in Geismar, Louisiana (“Rhodia Plant”) which is located adjacent to the phosphoric acid
production facility of PCSN located at Geismar, Louisiana (“Geismar Plant”). PCS desires to sell to Rhodia and Rhodia desires to purchase from PCS certain quantities of P2O5. PCSN requires sulfuric
acid for the production of phosphoric acid. Rhodia desires to sell to PCS and PCS desires to purchase from Rhodia a portion of the sulfuric acid required to produce phosphoric acid at the Geismar Plant. PCS and Rhodia have been conducting business
under the terms of the Original Agreement for over 10 years. Based on such premises and covenants set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties mutually
agree to amend and restate the Original Agreement as follows: 
  

	1.	DEFINITIONS 

  
 As used in this Agreement, the following terms shall have the following meanings: 
  

	 	1.1	“Green Acid” means the phosphoric acid produced by PCSN’s Geismar Plant and delivered by PCSN to Rhodia at the Rhodia Plant pursuant to the terms of this Agreement.

  

	 	1.2	“P2O5” means the phosphate content of a material as measured on a phosphorus pentoxide basis. 

  

	 	1.3	“Raffinate” means the dilute phosphoric and sulfuric acid stream separated from purified phosphoric acid at the Rhodia Plant and returned, to the Geismar Plant.

  

	2.	PURCHASE OF P2O5 

  

	 	2.1	 Base Requirements of Rhodia. PCS shall sell and deliver and Rhodia shall purchase and receive the P2O5 output requirements of
the Rhodia Plant up to (****) short tons per year (“Base Requirements”), taken in 

	 	 
approximately equal monthly quantities, under the terms and conditions of this Agreement. 

  

	 	2.2	Additional Requirements. PCS shall sell and deliver from PCSN’s Geismar Plant and Rhodia shall purchase and receive hereunder up to (****) short tons of
P2O5 output above the Base Requirements. This (****) short ton amount shall he referred to herein as the “Additional Requirements.” The purchase and sale of the “Additional Requirements,” as to term and
price, shall be governed by Article 10 hereof but shall otherwise be subject to the terms and conditions of this Agreement. PCSN shall, within the three-month period following the date of this Agreement, ascertain if, using its reasonable efforts,
it can provide an additional (****) short tons of P2O5 to Rhodia each year in light of technical and environmental factors associated with dedicating those tons to Rhodia. If it can, upon notice to Rhodia at the
end of such three-month period, the Additional Requirements of (****) short tons under this Section 2.2 shall be increased to (****) short tons. 

  

	 	2.3	Future Requirements. Rhodia shall advise PCS in writing if Rhodia has future requirements for P2O5 output at the Rhodia
Plant beyond the Additional Requirements. Such notice shall include Rhodia’s estimate of the volume, price and length of the purchase commitment that Rhodia desires and a proposal with respect to the additional sulfuric acid required to produce
such volume. Following such notice, the parties shall discuss and evaluate any such proposal in good faith. Neither party is obligated to purchase or sell any Future Requirements under a proposal that in its sole judgment is commercially
undesirable, technically infeasible or a violation of any law, regulation or applicable permit limitations. 

  

	 	2.4	Notices with Respect to Requirements of P2O5. Rhodia shall provide PCS written notice not later than August 30, of each year of Rhodia’s requirements for P2O5 for the following
calendar year. 

  

	3.	QUALITY 

  

	 	3.1	P2O5 delivered to Rhodia by PCS shall be in the form of Green Acid meeting the specifications set forth in Exhibit A, attached hereto and made a part hereof. These
Specifications shall be reopened and renegotiated in the event that process or raw material changes are implemented pursuit to Section 4.7 hereof. 

  

	4.	PRICE OF P2O5

  

	 	4.1	Price. 

  

	 	(a)	 For the Base Requirements of P2O5 delivered to Rhodia by PCS as determined by Section 4.2, Rhodia shall pay PCS the price
determined in accordance with Exhibit B, attached hereto and made a part hereof, subject 

  

 2 

	 	 
to possible adjustment resulting from an economic force majeure in accordance with Section 14 of this Agreement. 

  

	 	(b)	Actual price for phosphate rock paid by PCSN as defined in Exhibits B and C to this Agreement initially represented the **** price under the definition of Incoterms 1980 of the
International Chamber of Commerce, actually paid by PCSN’s predecessor to the (****) supplier for (****) phosphate rock under its (****) supply contract plus the cost of freight from (****) to Geismar under the relevant current charter party.

  
 Should PCSN for any reason purchase washed
(****) phosphate rock or phosphate rock with a BPL different from the BPL value assumed in Exhibits B and C, the appropriate components of EF1 shall be revised accordingly. 
  
 Should PCSN purchase phosphate rock that does not need to be washed for use in PCSN’s normal manufacturing process, then the appropriate components of EF1 shall be revised
accordingly. 
  
 Should PCSN purchase phosphate rock at a price
in excess of the fair market price, then upon Rhodia’s request the actual cost of PCSN phosphate rock shall be revised to eliminate any such excess cost resulting directly or indirectly from any commercial, industrial or financial arrangement,
or any other kind of agreement between PCSN, its shareholders or any other entity or person entitled to or in the position to act for PCSN or to direct its business or any and all portion of its business relating to PCSN’s sulfuric and/or
phosphoric activity and either (i) any phosphate rock and/or sulfur supplier, its shareholders and/or any entity or person entitled or in a position to direct its supplying business and/or (ii) any PCSN customer, its shareholder or any
entity or person entitled to or in a position to direct the business of said PCSN customer. 
  

	 	4.2	Measurement. Measurement of P2O5 sold and purchased shall be by tank car survey and composition analysis in accordance with
Exhibit D, attached hereto and made a part hereof. 

  

	 	4.3	Title. Title to P2O5 shall pass from PCS to Rhodia when P2O5 passes the inlet flange of each outgoing tank car or tank truck
for shipment from the Rhodia plant. 

  

	 	4.4	 Payment; Failure to Pay. Amounts payable by either party pursuant to the terms of this Agreement shall be billed monthly for P2O5 supplied during the prior month and shall be payable on or before the 15th day after receipt of each invoice. PCS has received from Rhodia an advance payment of $500,000 to cover PCSN’s 

  

 3 

	 	 
cost of production in progress (the “Advance Payment”). PCS shall credit Rhodia for the Advance Payment on its final invoice to Rhodia.

  

	 	4.5	Additional Deliveries 

  

	 	(a)	In consideration of the purchase price for P2O5 hereunder and the P2O5 and sulfuric acid
content of the Raffinate stream returned to PCSN, PCS shall deliver to Rhodia at no additional charge (i) up to 0.05 tons of additional P2O5 contained in Green Acid for each ton of P2O5 purchased by Rhodia hereunder and (ii) up to 0.25 tons of 100% sulfuric acid meeting the specifications set forth in Exhibit E, attached hereto and made a part hereof, for each ton of P2O5 purchased by
Rhodia hereunder. 

  

	 	(b)	If Rhodia requires more additional P2O5 than specified in Section 4.5(a)(i) and/or more sulfuric acid than specified in Section
4.5(a)(ii), PCS shall supply Rhodia with such additional requirements of P2O5 and sulfuric acid at the prices set forth in Section 4.1 or Section 7.3, as applicable. 

  

	 	4.6	Raffinate. 

  

	 	(a)	At Rhodia’s option, PCS shall take back Raffinate meeting the specifications and volume set forth in Exhibit F, attached hereto and made a part hereof.

  

	 	(b)	Rhodia shall pay PCS the amount determined in accordance with Exhibit G, attached hereto and made a part hereof, per ton of P2O5 purchased hereunder to
cover handling and recovery costs associated with the use of Raffinate in PCSN’s process. 

  

	 	(c)	Title to Raffinate shall not pass to Rhodia at any time under any circumstances unless and to the extent that Rhodia opts not to return the Raffinate stream to PCS.

  

	 	4.7	 Cost Reduction Measures. The parties hereby agree to jointly evaluate cost reduction initiatives that may result in revisions to the price formula for
P2O5 set forth in Section 4.1. Among the initiatives that the parties will consider are new technologies, process modifications and raw material changes. The parties are obliged to discuss and evaluate any proposed cost
reduction initiatives in good faith through the establishment of a steering committee composed of representatives of the parties, including at least one senior manager from each party who is not working at either the Rhodia Plant or the Geismar
Plant. Neither party is obligated to implement any proposal that in its sole judgment is commercially undesirable, technically infeasible or a violation of any law, regulation or applicable permit limitations. In the event any cost reduction
measures are implemented by the parties, this Agreement (including Section 

  

 4 

	 	 
4.1(b)) shall be amended to fully reflect the impact of such measures including, for example and without limitation, such factors as the costs of production
of Green Acid, the parties’ respective profit margins, the consumption of raw materials such as sulfuric acid, and the volume and uses of Raffinate. 

  

	5.	Future Expansions at Geismar. 

  

	 	5.1	Expansions to Meet Future Requirements. If Rhodia should provide a notice to PCS as provided by Section 2.3, in addition to any other alternatives being studied,
the parties shall discuss alternative financial arrangements for construction of any necessary expansions and/or modification to the Geismar facility of PCSN. As with Section 2.3, neither party shall be obligated to accept any terms,
arrangements, financing or any other condition which it in its sole discretion considers commercially undesirable, technically infeasible or a violation of any law, regulation or applicable permit limitation. 

  

	6.	DELIVERY OF P2Q5 

  

	 	6.1	Risk of Loss. Solely for purposes of establishing insurance coverage, risk of loss of the Green Acid shall pass from PCS to Rhodia when Rhodia takes custody of
P2O5 in the form of Green Acid at the delivery point (as hereinafter defined). Any insurance proceeds with respect to any loss or damage to Green Acid or Raffinate while in the custody of Rhodia, or to P2O5 before title passes to Rhodia as provided in Section 4.3, shall be allocated to PCS in amounts not to exceed the total value of the P2O5 at prices set forth in Section 4.1. Nothing in this
provision shall limit Rhodia’s obligation to pay for additional P2O5 under Section 4.5(b). 

  

	7.	SALE AND PURCHASE OF SULFURIC ACID 

  

	 	7.1	Sales and Specification. Rhodia shall sell and deliver to PCSN and PCSN shall purchase and take from Rhodia at the Geismar Plant sulfuric acid meeting the
specifications set forth in Exhibit H, attached hereto and made a part hereof, which shall be used by PCSN exclusively for the production of phosphoric acid that is marketed by PCS, upgraded by PCSN into other products or delivered to Rhodia
hereunder. For purposes hereof, PCSN shall make reasonable efforts to make arrangements for Rhodia to have access to the dock at the Geismar Plant for delivery of such sulfuric acid to PCSN. 

  

	 	7.2	Quantity. 

  

	 	(a)	 In each calendar year hereunder PCSN shall purchase and Rhodia shall supply between (****) of the amount of sulfuric acid required by PCSN for the production of
P2O5 purchased by Rhodia hereunder, determined in accordance with the following procedures. PCSN shall provide Rhodia with written notice not later than September 30 of each year 

  

 5 

	 	 
of the amount of sulfuric acid PCSN requires Rhodia to supply for the next succeeding calendar year. PCSN shall be obligated to supply the balance of its own
sulfuric acid requirements. The quantity of sulfuric acid that Rhodia supplies cannot exceed (****) of the amount of sulfuric acid required by PCSN for the production of Green Acid to be delivered to Rhodia in the next succeeding calendar year nor
be less than (****) of such amount. In the event that PCSN requires from Rhodia in any calendar year during the term of this Agreement less than (****) of the amount of sulfuric acid required by it for the production of Green Acid to be delivered to
Rhodia in such year (down to Rhodia’s (****) minimum supply level), PCS shall pay Rhodia (****) per ton of sulfuric acid short of the (****) level as liquidated damages and not as a penalty. 

  

	 	(b)	In the event that either party shall fail to provide in any calendar year during the term of this Agreement at least (****) of the amount of sulfuric acid it is committed to supply
for such year in accordance with Section 7.2(a) above, such party shall reimburse the other party for any financial loss the latter incurs as a result of such nonperformance within 5 business days of receipt of evidence of such loss.

  

	 	(c)	In the event that PCSN in any calendar year during the term of this Agreement accepts less than (****) of the amount it is committed to take for such year in accordance with
Section 7.2(a) above, PCS shall pay Rhodia (****) per ton of sulfuric acid short of such percentage to compensate Rhodia for its costs and expenses in canceling, or arranging alternative outlets for, its sulfuric acid supply, as liquidated
damages and not as a penalty. Any amount paid hereunder shall be in addition to any amounts payable under the last sentence of Section 7.2(a). 

  

	 	(d)	In no event shall Rhodia be required to supply a volume of sulfuric acid in excess of the amount required to produce the quantity of Green Acid delivered to Rhodia under this
Agreement. 

  

	 	7.3	Price. Price of sulfuric acid supplied to PCSN by Rhodia shall be set forth in Exhibit I, attached hereto and made a part hereof. 

  

	8.	PRICE ESCALATION 

  

	 	8.1	(****) Adjustments. The prices of P2O5 and sulfuric acid sold and purchased under this Agreement may be adjusted to reflect actual
changes in the (****) factors in the price formulas set forth in Sections 4 and 7 and Exhibits B and I. Such adjustments for (****) indices shall be made monthly and all other adjustments shall be made when they become effective.

  

 6 

	 	8.2	Record Keeping. The parties shall maintain accounting and budget systems sufficiently detailed to provide a reasonably complete basis for cost determination and
allocation by an independent auditor. Where costs include man-hours, the parties shall keep records such as work orders, logs and other time records sufficiency detailed to verify the number of hours worked per person. 

  

	 	8.3	Independent Auditor. On an annual basis Rhodia and PCS may designate a mutually acceptable independent auditor who shall have access at all reasonable times to such
records and facilities as may be required to verify actual costs conversion ratios, inventories and similar matters related to this Agreement. Such audit shall be consistent with generally accepted accounting practices. If the results of any audit
disclose a material error of omission or commission in the method of calculation of any charge hereunder, such affected calculation or charge shall be subject to retroactive adjustment relating back no further than the previous audit or
reconciliation. The parties shall share equally the cost of such annual audit. 

  

	9.	TERM 

  

	 	9.1	Initial Term. This Agreement shall be in effect from the Effective Date and, subject to earlier termination as set forth in this Section, shall continue in effect

	 	(b)	Rhodia represents and warrants to PCS that all sulfuric acid to be delivered by Rhodia to PCS pursuant to the terms of this Agreement shall meet the specifications as set forth in
Exhibit H. 

  

	 	(c)	Subject to the preceding Sections 12.2(a) and 12.2(b), RHODIA MAKES NO REPRESENTATION OR WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, IN FACT OR IN LAW, INCLUDING BUT NOT LIMITED TO
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND THOSE ARISING FROM A COURSE OF DEALING OR USAGE OF TRADE, OR ANY OTHER MATTER WITH RESPECT TO THE SULFURIC ACID. 

  

	 	12.3	Limitation of Liability. 

  

	 	(a)	PCS acknowledges that the delivery of Rhodia’s requirements of Green Acid meeting the specifications set forth in Section 3 and Exhibit A hereof is critical to
Rhodia’s realizing the value of its investment in the Rhodia Plant. Therefore, PCS acknowledges and affirms Rhodia’s right to enforce in law or equity the obligations of PCS to provide Green Acid hereunder, subject, however, to the
provisions of Sections 12.3(b), 12.3(c) and 13.1 

  

 9 

	 	(b)	No party shall be liable to any other for special, incidental, indirect, punitive or consequential damages (including, but not by limitation, lost profits) in excess of the purchase
price of the goods in respect of which such claim is made resulting from immaterial breaches of warranty with respect to the supply of Green Acid or sulfuric acid hereunder, regardless of whether such liability is based upon breach of this
Agreement, negligence, breach of warranty or otherwise. For purposes of this Section, “immaterial breach” shall be defined as a breach of warranty continuing for no more than 120 consecutive hours following receipt of written notice of
such breach by the breaching party. The cumulative annual total of up to 360 hours during which any breach of warranty continues after notice shall also be deemed an “immaterial breach” for purposes of this Section.

  

	 	(c)	All claims by any party against any other party with respect to the Green Acid or sulfuric acid (whether based in contract, warranty, negligence, strict liability, tort, or
otherwise) shall be deemed waived unless made in writing and received by the other party within ninety (90) days after delivery of the Green Acid or sulfuric acid in respect to which the claim is made. 

  

	 	12.4	Indemnification. 

  

	 	(a)	Rhodia. Rhodia shall hold harmless and indemnify PCS and PCSN (referred to collectively in this Section 12.4 as “PCS”) for all damages, claims or actions, including injury to or death of persons or damage to property, caused by or resulting from the operation of
the Rhodia Plant or Rhodia’s handling or possession of Green Acid, sulfuric acid, or Raffinate pursuant to this Agreement. 

  

	 	(b)	PCS. PCS shall hold harmless and indemnify Rhodia for all damages, claims or actions, including injury to or death of persons or damage to property, caused by or
resulting from the operation of the Geismar Plant or PCS’s handling or possession of Green Acid, sulfuric acid, or Raffinate pursuant to this Agreement. 

  

	 	(c)	 Employees. Employees or representatives of any party, who are present under any provision of this Agreement on the properties of another party, shall
be there at the risk of the employer of such persons, and such employer agrees to fully protect and indemnify the other party against any liability to such employees or representatives, except in those instances where the liability grows out of the
sole negligence or willful misconduct of such other party. Further, each party agrees to save harmless and indemnify the other against claims for injuries or damages to persons or property occurring on the indemnified party’s property and
caused or 

  

 10 

	 	 
alleged to have been caused by employees or the other party while such employees were present on the indemnified party’s property.

  

	13.	PERFORMANCE 

  

	 	13.1	Excuse of Performance. 

  

	 	(a)	Force Majeure. No liability shall result from delay in performance caused by circumstances beyond the control of the party affected, including, but not limited to act
of God, fire, flood, war, government action, equipment failure, labor trouble or shortage, inability to obtain adequate material, equipment or transportation. Quantities so affected may be eliminated from the contract at the discret on of the party
affected without liability, but the contract shall remain otherwise unaffected. 

  

	 	(b)	Efforts to Overcome Force Majeure. Each of PCS, PCSN and Rhodia agrees that if such party is prevented by force majeure from performing in whole or in part its
undertakings hereunder, it shall diligently use all reasonable efforts to overcome such force majeure and to resume in full performance of all of its obligations hereunder. 

  

	 	(c)	Settlement of Strikes and Labor Disturbances. The settlement of strikes, or labor disturbances shall be entirely within the discretion of the party having the
difficulty, and any requirement that force majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes or labor disturbances by acceding to the demands of the opposing party or parties when such course is
inadvisable in the discretion of the party having the difficulty. 

  

	 	(d)	Notice of Force Majeure. In the event that PCS, PCSN or Rhodia shall be rendered unable, wholly or in part, by force majeure, to carry out its obligations, other than
to make payments, notice and full particulars of such force majeure shall be given to the other parties as promptly as practicable after the occurrence of such force majeure and provided such notice is given as aforesaid, the obligations hereunder
of the party giving such notice, so far but only so far as they are affected by such force majeure, shall be suspended during the continuance of any inability so caused but for no longer period, and such party shall remedy such inability with all
reasonable dispatch. 

  

	 	(e)	 Deliveries. In the event delivery of Green Acid by PCS to Rhodia is suspended or not made by reason of this Section 13, Rhodia shall have the
right to purchase Green Acid to replace such quantities from third parties. Under such circumstances, unless excused by force majeure, PCS shall not be relieved of its obligation hereunder to receive and process Raffinate, 

  

 11 

	 	 
provided that PCS shall not be required to add new, handling or processing systems and/or to transport Raffinate offsite and further provided that such
handling and/or processing is permitted under the then-existing governmental permits that have been issued to PCS or PCSN and is not violative of any law or regulatory requirement. 

  

	14.	ECONOMIC FORCE MAJEURE 

  

	 	14.1	If, at any time during the term of this Agreement, PCS or PCSN (collectively referred to as “PCS” for purposes of this Section) reasonably determine that:

  

	 	(a)	it is not in PCS’s economic interest to run the Geismar Plant due to events or circumstances outside of PCS’s control, including but not limited to market pricing
conditions or government regulations, which eliminate PCS’s earnings at the Geismar Plant (before interest and taxes as determined in accordance with GAAP) for a consecutive eighteen-month period after taking into account the supply of
P2O5 under this Agreement but excluding the impact on the Geismar Plant of strategic and
manufacturing decisions implemented by PCS in its sole discretion, including but not limited to the shift of production, to other PCS sites; and 

  

	 	(b)	PCS would shut down the Geismar phosphoric acid plant solely due to such events or circumstances, were it not for PCS’s obligations to Rhodia under this Agreement;

  
 (such determinations constituting a declaration by PCS of
“economic force majeure”), then PCS shall notify Rhodia in writing of such determinations and, beginning on the date of PCS’s notice (“Notice Date”) and ending no later than six months after the Notice Date, the parties will
discuss and evaluate in good faith proposals to address such economic force majeure in a manner that (i) does not obligate Rhodia to suffer any adverse financial or operational consequences therefrom and (ii) provides PCS with some relief
from the financial consequences thereof. Upon expiration of such period, Rhodia, in the exercise of its sole discretion and upon written notice to PCS, will select a proposal to address such economic force majeure should it continue, which approach
shall be implemented on or before eighteen months after the Notice Date provided that PCS has the right to reject any approach selected by Rhodia and continue to operate under the terms of this Agreement. Such approaches may include, by way of
illustration and without limitation: 
  

	 	A.	Rhodia’s lease or purchase of the Geismar Plant at mutually acceptable financial terms and on mutually acceptable terms and conditions; or 

  

	 	B.	Rhodia’s commitment to purchase (****) of tie P2O5 output of the Geismar Plant run at maximum capacity at the then current price for the Base
Requirements; or 

  

 12 

	 	C.	PCS’s agreement to permit Rhodia to purchase and have delivered Green Acid to replace all amounts deliverable hereunder, which agreement would entail access to all docks at the
Geismar Plant, utilization of all Green Acid storage facilities, supply of steam and power and funding of capital investments for handling Raffinate, among other items; or 

  

	 	D.	PCS’s agreement to supply Rhodia with purified phosphoric acid of a quality and in amounts equivalent to that produced by Rhodia at the Rhodia Plant at a price equal to
Rhodia’s cash cost of production therefor. 

  

	15.	INSURANCE 

  

	 	15.1	Insurance Certificate. Each party shall furnish the other party a Certificate of Insurance coverages, which certificate shall state that insurance coverage shall not
be terminated, reduced, or allowed to expire without first giving the other party to this Agreement at least thirty (30) days prior written notice. 

  

	 	15.2	Minimum Insurance Requirements. Each party shall take out and maintain at its own expense during the term of this Agreement at least the following insurance coverage
which minimums the parties shall review and adjust prior to the commencement of any renewal term for Rhodia’s Base Requirements: 

  

			
	 COVERAGE

	  	 LIMITS

	 	15.3	Contractual Endorsement. The insurance certificate described in this Section shall include a certification that the above-described insurance coverage includes
contractual coverage for the liability under this Agreement of the relevant party. 

  

	 	15.4	Waiver of Subrogation. Each party shall secure from the company carrying such party’s Worker’s Compensation and Employer’s Liability insurance coverage
a waiver of subrogation in favor of the other party to this Agreement and its employees and shall furnish to such other party a copy of such waiver. 

  

 13 

	 	15.5	No Limitation On Liability. The insurance requirements set forth herein are minimum coverage requirements and are not to be construed in any way as a limitation
on any party’s liability. 

  

	16.	DELIVERY 

  

	 	16.1	Delivery Point. All Green Acid or Sulfuric Acid provided in accordance with Section 4.5(a) hereof (referred to solely for purposes of Sections 16.1 and 16.2
hereof as “Sulfuric Acid”) furnished hereunder by PCS to Rhodia shall be supplied and delivered to Rhodia at the boundary line of the Rhodia Plant at the point where the pipeline through which the Green Acid or Sulfuric Acid is transported
crosses such boundary line. Such point is referred to herein as “delivery point”. 

  

	 	16.2	Responsibility for Piping. All piping and other equipment used in manufacturing, generating, and delivering the Green Acid or Sulfuric Acid to the delivery point shall
