2.Purchase Price. The purchase price to be paid by Purchaser to Seller for the Property (the “Purchase Price”) shall be Twenty-One Million Nine Hundred Eighty Six Thousand Nine Hundred Ten and No/100 Dollars ($21,986,910.00), which amount is equal to the product of ONE AND 50/100 DOLLARS ($1.50) multiplied by the number of square feet contained within the boundaries of the Property based on an assumed acreage of 336.5 acres of land. If Purchaser obtains an Updated Survey as described in Section 4(a) hereof, then the Purchase Price shall be adjusted (increased or decreased) to an amount equal to the product of ONE AND 50/100 DOLLARS ($1.50) multiplied by the number of square feet contained within the boundaries of the Property as determined by the Updated Survey; provided, however, if the area determined by the Updated Survey varies from the assumed acreage set forth above by more than one percent (1.0%), then Seller shall have the right to terminate this Agreement by written notice given to Purchaser by the earlier of the Closing Date or five (5) days after Seller receives a copy of the Updated Survey from Purchaser reflecting a reduction in square footage of the Property by more than one percent (1%) from the above estimated acreage. If Seller timely elects to terminate the Agreement as aforesaid, the Earnest Money shall be returned to Purchaser and neither party shall have any further rights, duties or obligations hereunder other than the Surviving Duties (hereinafter defined).

Seller hereby agrees to cooperate fully with Purchaser and to provide Purchaser with such information and documentation as Purchaser reasonably requests in order to assist Purchaser in making the test or inspections or in evaluating the Property, provided that Seller shall not be required to incur any out-of-pocket cost (not paid or reimbursed by Purchaser) in providing information and cooperation. Purchaser is also free to contact government authorities regarding the Property, its condition, the availability of utility service and the development potential of the Property and Purchaser shall not be liable to Seller for any consequences thereof.

(a)Conditions to Closing. The obligations of Purchaser under the terms of this Agreement shall be contingent and conditioned upon the following:

(i)Performance of Covenants. That Seller shall have timely and fully performed all of

its material covenants and agreements due to be performed by Seller under this Agreement, unless waived in writing by Purchaser or deemed waived pursuant to any express provision of this Agreement.

(ii)Representations and Warranties. That all of Seller's representations and warranties in this Agreement were true and correct in all material respects as of the date given, and are true and correct in all material respects as of the Closing Date.

(iii)Condition of the Property. The Property shall be in the same condition as on the Effective Date, without any flooding, subsidence or other occurrence having materially affected its topography, its surface or subsurface geological condition for building purposes, or otherwise materially affecting its physical characteristics.

(iv)At Closing, Purchaser may, at its option and at its sole cost, purchase a TLTA Form T-1 Owner Policy of Title Insurance in the form committed to pursuant to the Title Commitment which as a condition to Purchaser’s obligations hereunder must be issuable to Purchaser at Closing subject only to the Permitted Encumbrances and standard form exceptions to coverage provided for therein (with such endorsements as Purchaser qualifies and pays for, if any) (the “Title Policy”); provided, however, that if Purchaser’s inability to obtain the Title Policy in the conditions required hereby is solely due to any action or breach of this Agreement by Purchaser then this condition shall be deemed satisfied.

If any of the conditions to Closing provided for in this Section 9(a) are not timely satisfied and do not result from Seller’s default, then Purchaser shall have the option at or prior to the Closing to either (i) terminate this Agreement by written notice to Seller, in which event the Earnest Money deposited by Purchaser with the Title Company shall be refunded to Purchaser free and clear of all rights and claims of Seller with respect thereto, and neither Purchaser nor Seller shall have any further rights or obligations under this Agreement except for the Surviving Duties, or (ii) waive such condition by written notice thereof to Seller (without waiving any cause of action against Seller in the event of Seller's misrepresentation or breach of covenant or warranty) and proceed to the Closing without any reduction in the Purchase Price as a result of such failure of condition. If the condition to Closing is not satisfied as a result of Seller’s default, then Purchaser may pursue its remedies for such default by Seller.

(b)Right of First Refusal.

(i)Seller has disclosed to Purchaser the existence of a right of first refusal affecting the Property in favor of Rentech Nitrogen Partners, L.P. (“RNP”), pursuant to that certain Right of First Refusal and Purchase Option Agreement dated as of November 1, 2012, between Agrifos and RNP, a Memorandum of which is recorded under Harris County Clerk’s File No. 20120515434 in the Real Property Records of Harris County, Texas (listed as exception/requirement 8 on Schedule C of the Title Commitment) (the “ROFR Agreement”). Seller represents that it has in its possession an originally executed Termination of Right of First Refusal and Purchase Option Agreement in recordable form (the “Termination”) (a true and complete copy of which is attached hereto as Exhibit K) which Seller has a right to record in the Real Property Records of Harris County, Texas, upon satisfaction of the conditions stated in the ROFR Agreement. Upon Seller’s execution and acceptance of this Agreement, Seller is obligated to deliver title to the Property to Purchaser at Closing free and clear of the ROFR Agreement any rights of RNP (and its successor and assigns) thereunder. By Seller’s execution and acceptance of this Agreement, Seller is deemed to (and hereby does) represent and warrant to Purchaser that (A) Seller has given notice to RNP in compliance with the ROFR Agreement as necessary to trigger RNP’s twenty (20) day period in which to elect to purchase the Property, and (B) RNP failed to exercise its right to purchase the Property under its right to do so under the ROFR Agreement within the time period afforded to RNP to make such election thereunder.

(ii)Seller represents that full and complete copies of the ROFR Agreement and the Termination have been delivered to Purchaser and the Title Company prior to the date of Purchaser’s execution and delivery hereof to Seller, and have not been amended. Within one (1) business day after the execution of this Agreement by Purchaser and delivery of the Purchaser executed Agreement to Seller, Seller agrees to give notice of such offer to RNP and provide RNP a copy of this Agreement and any other information required to

be submitted to RNP pursuant to the ROFR Agreement so that the time period for RNP to elect to exercise its right of first refusal to purchase the Property runs at the earliest possible time, and provide a full and complete copy thereof to Purchaser and Title Company. Even though this Agreement is not yet binding and in effect, if Seller fails to comply with the requirements of the preceding sentence, then Purchaser’s offer evidenced by its execution and submission of this Agreement to Seller shall automatically be deemed revoked and void. Seller represents and warrants to Purchaser that prior to the date of Purchaser’s execution and delivery of this Agreement to Seller, Seller has delivered the Termination to the Title Company together with written instructions to the Title Company authorizing the Title Company to record the Termination upon the Closing pursuant to this Agreement, and it is a condition to Seller’s execution and acceptance of this Agreement that such Termination will have remained on deposit with the Title Company at the same time Seller executes and accepts this Agreement. Seller shall not revoke its escrow instructions for the Termination or withdraw the Termination from the possession of the Title Company prior to Closing or termination of this Agreement.

10.Defaults and Remedies.

(a)Seller's Default. If Seller fails to perform any of Seller's obligations under this Agreement for any reason other than (i) the termination of this Agreement by Seller or Purchaser pursuant to any right to terminate expressly set forth in this Agreement (other than this Section), or (ii) Purchaser's failure to perform Purchaser's obligations when required to be performed under this Agreement, and such default by Seller (other than default in performance due at Closing, for which there is no notice or cure right) is not cured by the sooner of Closing or five (5) business days after Purchaser gives Seller written notice of such default, or if any of Seller's representations or warranties set forth in this Agreement are found to be materially inaccurate or untrue prior to or at Closing, then Purchaser, at Purchaser's option and (except as set forth below) as Purchaser's sole and exclusive remedy, shall have the right.

(i)to terminate this Agreement by giving written notice thereof to Seller, whereupon all Earnest Money shall be refunded to Purchaser free and clear of all rights and claims of Seller with respect thereto, and neither Purchaser (except as provided below in this Section 10(a)) nor Seller shall have any further rights or obligations hereunder except for the Surviving Duties; or

(ii)to enforce specific performance of the obligations of Seller under this Agreement and collect from Seller in such proceeding all of Purchaser's costs of court and legal fees incurred in connection therewith.

The foregoing remedies are, however, in addition to Purchaser’s rights, as they may exist at law, to obtain injunctive or equitable relief to prevent Seller’s breach, threatened breach or continued breach of any pre-Closing covenant of Seller under this Agreement, or to obtain declaratory judgment relief where applicable. Regardless of which remedy is selected by Purchaser, if Seller has made a material misrepresentation or materially breached a warranty contained in this Agreement, then Purchaser shall also be entitled to recover from Seller any damages suffered by Purchaser by reason thereof subject to the limitations set forth below; provided, however, that any suit or action for breach of any of the representations or warranties of Seller set forth herein must be filed with a court of competent jurisdiction within the Survival Period or any claim based thereon shall be deemed irrevocably waived. Unless expressly made to survive, all other obligations and covenants of Seller contained in this Agreement shall be deemed to have been merged into the Deed and shall not survive the Closing. Notwithstanding the foregoing, however, if actions taken by Seller make it impractical or impossible for Purchaser to obtain the substantial benefit of its bargain by enforcement of specific performance against Seller, then Purchaser shall be entitled as an additional remedy (unless and until it elects option (2) hereof) to recover from Seller damages in the amount of its out of pocket costs and expenses in connection with this Agreement not to exceed One Hundred Fifty Thousand and No/100 Dollars ($150,000.00) plus its other proven damages not to exceed an additional One Hundred Fifty Thousand Dollars ($150,000.00). The foregoing provisions do not govern the remedies of the parties after Closing with regard to obligations and liabilities of the parties under this Agreement which survive Closing, or arising under documents delivered by the parties to consummate the Closing of this transaction, such as claims under a warranty of title in the Deed, etc.

If Purchaser notifies Seller within one (1) year after Closing (the “Survival Period”) that Purchaser discovered post-Closing that any representation or warranty made by Seller in this Agreement was not true and correct in any material respect and specifying the breach with particularity, subject to the limitations set forth below, Purchaser shall have available all remedies at law or in equity as a consequence thereof. If Purchaser does not notify Seller of the breach of any of its representations and warranties set forth in this Agreement and institute a lawsuit therefor in a court of competent jurisdiction prior to the expiration of the Survival Period after the Closing, Purchaser shall be deemed to have waived all of its rights to claim and sue for any breach by Seller of any of its representations and warranties made in this Agreement. Further, Purchaser agrees that any recovery against Seller in respect of Seller’s covenants, indemnities, representations or warranties hereunder or under any other agreement, document, certificate or instrument delivered by Seller to Purchaser hereunder at Closing other than claims under the Indemnity Agreement and the Deed, or under any law applicable to the Property or this transaction, shall be limited to Purchaser’s actual damages (including consequential damages if and to the extent permitted by law) not in excess of ten percent (10%) of the Purchase Price paid to Seller at Closing in the aggregate for all such claims collectively, and that in no event shall Purchaser be entitled to seek or obtain any other damages of any kind, including, without limitation, speculative or punitive damages, or actual or consequential damages in excess of the stated cap. It is acknowledged that this cap applies in the aggregate to all damages collectively. The aforesaid cap on Purchaser’s recoverable damages shall not apply to (and shall exclude) Seller’s indemnity obligations in the Indemnity Agreement, Seller’s warranty of title in the Deed, Seller’s post-Closing proration adjustment obligations, and reasonable attorneys’ fees, costs of litigation, and court costs.

(a)Purchaser's Default. If Purchaser fails to perform any of Purchaser's obligations under this Agreement for any reason other than (i) the termination of this Agreement by Seller or Purchaser pursuant to any right to terminate expressly set forth in this Agreement (other than this Section), or (ii) Seller's failure to perform Seller's obligations when required to be performed under this Agreement, and such default by Purchaser (other than default in performance due at Closing, for which there is no notice or cure right) is not cured by the sooner of Closing or five (5) business days after Seller gives Purchaser written notice of such default, then Seller, as Seller's sole and exclusive remedy, shall have the right to terminate this Agreement by giving written notice thereof to Purchaser, in which event the Earnest Money shall be delivered to Seller as liquidated damages free and clear of all rights and claims of Purchaser with respect thereto, and neither Purchaser nor Seller shall have any further rights or obligations under this Agreement. Seller hereby expressly waives all remedies and causes of action against Purchaser for Purchaser's failure to perform any of Purchaser’s obligations at Closing other than the liquidated damages provided for in this Section 12(b), including, without limitation, any right to enforce specific performance of Purchaser's obligations. The foregoing remedies are, however, in addition to Seller’s rights, as they may exist at law, to obtain injunctive or equitable relief to prevent Purchaser’s breach, threatened breach or continued breach of any pre-Closing covenant of Purchaser under this Agreement, but Seller is waiving the right to seek specific performance of Purchaser’s obligations to close this transaction. Nothing herein shall be construed as a waiver of or limit Seller’s right to pursue all remedies against Purchaser at law and in equity with respect to Surviving Duties and any post-Closing obligations of Purchaser, including, without limitation, Purchaser’s obligations under the Indemnity Agreement.

11.Real Estate Commission. Purchaser and Seller each represents to the other that there are no real estate agents or brokers entitled to a commission in connection with this purchase and sale of the Property as the result of any act, deed, promise or agreement of such party, other than CBRE, Inc. (“Purchaser’s Broker”). Purchaser hereby agrees to indemnify and hold harmless Seller from and against any and all claims of any agent, broker, finder or other similar party (other than Purchaser’s Broker) claiming through Purchaser, and Seller hereby agrees to indemnify and hold harmless Purchaser from and against any and all claims of any agent, broker, finder or other similar party (including Brokers) claiming through Seller. Seller hereby agrees to pay Purchaser’s Broker in cash, at and only in the event of a Closing of this transaction, a real estate commission equal to three percent (3.0%) of the Purchase Price calculated in accordance with the provisions of Section 2 hereof.

12.Seller's Non‑Foreign Status. Seller represents and warrants that Seller is not a “foreign person,” as defined in Section 1445 of the Internal Revenue Code of 1986, as amended, and in the Rules and Regulations promulgated by the Treasury Department with respect thereto (collectively, “Federal Tax Law”).

Therefore, at the Closing, Seller will deliver to Purchaser a certificate so stating, subscribed and sworn to by Seller, complying with Federal Tax Law (the “Certificate as to Non-Foreign Status”). If Seller fails to deliver the Certificate as to Non-Foreign Status at the Closing, subscribed and sworn to as described above, then, in either such event, the Title Company is hereby authorized to withhold from the Purchase Price otherwise payable to Seller, all sums required to be withheld by Purchaser under Federal Tax Law (and if the cash portion of the Purchase Price is insufficient for such purpose, then Seller shall deliver the shortfall in cash into escrow with the Title Company at Closing), and the Title Company will deliver such amount withheld (and/or delivered by Seller) to the Internal Revenue Service together with the appropriate forms prescribed by the U.S. Department of the Treasury, with copies being contemporaneously sent to both Seller and Purchaser.

13.Time. Time is of the essence in all matters pertaining to the performance of this Agreement.

14.Notices. Any notice, demand or request which may be permitted, required or desired to be given in connection therewith shall be given in writing and directed to Seller and purchaser as follows:

Notices shall be sent and given, and deemed properly delivered and received, only as follows: (i) on the date delivered to the party’s effective notice address hereunder, if hand delivered; (ii) on the date delivered to the party’s effective notice address hereunder, if delivered by nationally-recognized overnight courier or private, receipted same-day courier; (iii) on the earlier of the date of actual delivery at the party’s effective notice address hereunder (which will be deemed the date of first attempted delivery if refused or left unclaimed), or three (3) postal business days after deposited in the care, custody or control of the U.S. Postal Service, if by U.S. Mail, registered or certified, return receipt requested, properly addressed and postage prepaid, or (iv) on the date sent via facsimile transmission and confirmed as successful delivery by the sender’s transmission equipment, provided that the sender contemporaneously sends such notice by

regular U.S. mail (or any other means allowed for delivery above). Any party may change its notice address and/or facsimile number for purposes hereof to any address within the continental United States that is (or includes) a street address that allows overnight delivery to such address by giving written notice of such change to the other parties hereto at least fifteen (15) days prior to the intended effective date of such change. Notwithstanding that email addresses are provided herein, email shall not be an effective means of giving notice under this Agreement for any purpose even if actually received and read.

15.Authority. Each party to this Agreement warrants and represents to the other that such party has full power and authority to enter into and perform its obligations under this Agreement in the names, titles and capacities herein stated and on behalf of any entities, persons, estates or firms represented or purported to be represented by such person, and that all approvals, consents and authorizations necessary or required by any state and/or federal law or private agreement in order for such party to enter into and perform its obligations under this Agreement have been obtained and all legal requirements fully complied with.

16.Condemnation.

(a)Risk of Loss. Seller shall bear all risk of condemnation of the Property until the Closing.

(b)Purchaser's Option to Cancel. If prior to the Closing any material portion of the Property is taken by eminent domain, or made the subject of condemnation proceedings (or proposed or threatened condemnation proceedings), Seller shall give Purchaser prompt written notice thereof and Purchaser may elect, by written notice to Seller within twenty (20) days after Purchaser shall have received written notice of such event from Seller, to cancel this Agreement without further liability. If Purchaser elects to cancel this Agreement, as aforesaid, then the Title Company will return the Earnest Money (and any Extension Payment) to Purchaser free and clear of all rights and claims of Seller with respect thereto, and thereafter neither Seller nor Purchaser shall have any further rights or obligations hereunder except for the Surviving Duties. For purposes hereof, a “material portion of the Property” means any portion of the Property that Purchaser determines in its good faith judgment will have a material, adverse affect on Purchaser’s proposed use, improvement or operation of the Property after Closing for the purposes contemplated by Purchaser, or will materially impede full exercise or use of important access, drainage or other appurtenances to (or comprising part of) the Property, or will materially increase the cost of operation of the Property for Purchaser’s intended uses, or materially reduce the resale value of the Property or future legally permitted uses to which it may be put in the future.

(c)Failure to Cancel. If any portion of the Property is taken by eminent domain or made the subject of condemnation proceedings (or proposed or threatened condemnation proceedings), and Purchaser does not elect to cancel this Agreement pursuant to Section 16(b) hereof, then at the Closing the following shall occur:

(i)Seller shall credit on account of the Purchase Price the amount of all condemnation awards actually received by Seller (whether retained by Seller or paid directly to the holder of any lien on the Property).

(ii)Seller shall also assign, transfer and set over to Purchaser all of Seller's right, title and interest in and to any awards that may be made with respect to any pending or future condemnation proceeding

(d)Control of Condemnation Proceedings After Purchaser is “At-Risk”. If Purchaser has not cancelled this Agreement, Purchaser shall be entitled to participate in any condemnation proceeding on an equal basis with Seller and veto any proposed award or settlement offer not acceptable to Purchaser. If Seller's lienholder on the Property is entitled under its lien instruments to control such condemnation proceeding, and if such lienholder makes any material substantive decision in such proceeding that is unacceptable to Purchaser in Purchaser's sole and absolute (including arbitrary) discretion, then Purchaser shall be entitled to terminate this Agreement by written notice to Seller and receive a full refund of the Earnest

Money free and clear of all rights and claims of Seller with respect thereto, and neither Seller nor Purchaser shall have any further rights or obligations hereunder except for Surviving Duties.

17.Entire Agreement. This Agreement represents the entire agreement by and between Purchaser and Seller with regard to the subject matter dealt with herein, and it may not be modified except by written amendment executed by Purchaser and Seller.

18.Effective Date. The “Effective Date” hereof is the date on which the Title Company receives one or more fully executed copies of this Agreement, signed by Seller and Purchaser (including if delivered by fax or electronically), as indicated on its receipt signature page to this Agreement.

19.Successors and Assigns. The terms and provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective heirs, personal representatives, successors and permitted assigns. Seller hereby acknowledges and agrees that Purchaser may assign all or part of its interest in this Agreement to any person or entity without the prior consent of Seller; provided, however, no such assignment shall release Purchaser from any of its liabilities or obligations under or with respect to this Agreement.

20.Governing Law. The terms, provisions and conditions of this Agreement shall be governed by and construed in accordance with the laws of the State of Texas. Venue for all suits and actions arising out of or in connection with this Agreement shall be proper only in the state and federal courts sitting in Harris County, Texas, and each party hereby consents to the assertion of personal jurisdiction by such courts over such party for the limited purposes of such suit but does not waive requirement for service of process in the manner prescribed by law.

21.Severability. If any provision of this Agreement shall, for any reason, be held to be illegal, invalid or unenforceable, then the other provisions of this Agreement shall not be rendered invalid or otherwise affected thereby, all of which remaining provisions shall continue in full force and effect to the maximum extent permitted by applicable law.

22.Survival of Covenants; Further Assurances. The representations, warranties and covenants of Seller contained in this Agreement shall (to the extent not fully performed at or before Closing) survive the Closing. Seller and Purchaser each agree to execute and deliver such other documents, on or after the Closing Date, as are reasonably necessary to give effect to and carry out the transaction herein contemplated.

23.Exhibits. All exhibits referenced in this Agreement as being attached hereto are incorporated herein by this reference and shall constitute a part of the terms, covenants, conditions and provisions hereof, as if set forth herein verbatim (except to the extent that an Exhibit is an existing executed document or Closing document form, in which event they are incorporated for information and reference only and the terms thereof are not binding on the parties unless and until executed as a Closing document delivered under the terms hereof).

24.Certain Required Notices/Disclosures.

(a)Notice Regarding Possible Liability For Additional Taxes. If for the current ad valorem tax year the taxable value of the Property is determined by a special appraisal method that allows for appraisal of the Property at less than its market value, Purchaser may not be allowed to qualify the Property for that special appraisal in a subsequent year and the Property may then be appraised at its full market value. In addition, the transfer of the Property or a subsequent change in the use of the Property may result in the imposition of an additional tax plus interest as a penalty for the transfer or the change in use of the Property. The taxable value of the Property and the applicable method of appraisal for the current tax year is public information and may be obtained from the tax appraisal district established for the county in which the Property is located. If Seller has claimed the benefit of laws permitting a special use valuation for the purpose of ad valorem taxes on the Property and if, after the Closing, Purchaser changes the use of the Property from its

present use and such change results in the assessment of additional taxes, then those additional taxes will be Purchaser's obligation, notwithstanding that some or all of those additional taxes may relate back to the period prior to Closing.

(b)Notice Regarding Possible Annexation. IF ANY PORTION OF THE PROPERTY IS LOCATED OUTSIDE THE LIMITS OF A MUNICIPALITY, THE PROPERTY MAY NOW OR LATER BE INCLUDED IN THE EXTRATERRITORIAL JURISDICTION OF A MUNICIPALITY AND MAY NOW OR LATER BE SUBJECT TO ANNEXATION BY THE MUNICIPALITY. EACH MUNICIPALITY MAINTAINS A MAP THAT DEPICTS ITS BOUNDARIES AND EXTRATERRITORIAL JURISDICTION. TO DETERMINE IF ANY PORTION OF THE PROPERTY IS LOCATED WITHIN A MUNICIPALITY’S EXTRATERRITORIAL JURISDICTION OR IS LIKELY TO BE LOCATED WITHIN A MUNICIPALITY’S EXTRATERRITORIAL JURISDICTION, PURCHASER IS ADVISED TO CONTACT ALL MUNICIPALITIES LOCATED IN THE GENERAL PROXIMITY OF THE PROPERTY FOR FURTHER INFORMATION.

(c)Real Estate Broker Notice to Purchaser. The Texas Real Estate License Act requires that Purchaser be advised that he should either (i) have an attorney examine an abstract of title to the Property, or (ii) obtain a title insurance policy covering the Property. Notice to that effect is, therefore, hereby given to and acknowledged by Purchaser.

(d)Disclosure Regarding Landfill. Seller has disclosed to Purchaser that a portion of Tract 1 of the Property is affected by a closed municipal landfill as delineated on the drawing attached hereto as Exhibit H (the “Landfill). The Indemnity Agreement will provide that Purchaser and Orion will indemnify and defend Seller from and against any claims, liabilities, costs and expenses (including reasonable attorney fees) arising as a result of any operations conducted by Purchaser or its successors or assigns on the Landfill, including, without limitation, any excavation, drilling or construction thereon.

25.Surviving Duties. The term “Surviving Duties” shall mean any and all duties or obligations which are expressly stated to survive termination of this Agreement or Closing hereunder, including, without limitation, Purchaser’s obligations contained in Section 4 hereof and any indemnity obligations set forth herein.

26.Saturday, Sunday or Legal Holiday. If any date set forth in this Agreement for the performance of any obligation by Purchaser or Seller or for the delivery of any instrument or notice should be on a Saturday, Sunday or legal holiday, then the compliance with such obligations or delivery shall be deemed acceptable on the next business day following such Saturday, Sunday or legal holiday. For purposes of this Section, “legal holiday” shall mean any state or federal holiday for which financial institutions or post offices are generally closed in Harris County, Texas, for the observance thereof.

27.Headings; Construction. The headings contained in this Agreement are for reference purposes only and shall not modify or affect this Agreement in any manner whatsoever. Wherever required by the context, any gender shall include any other gender, the singular shall include the plural, and the plural shall include the singular. All references in this Agreement to “herein”, “hereunder” or “hereby” shall refer to this entire Agreement rather than any particular section, paragraph, subparagraph, clause or provision, unless specifically stated otherwise.

28.Time of Acceptance. In the event Seller shall fail, by 5:00 P.M., local Houston (Texas) time, on February 25, 2014, to accept this Agreement by executing a counterpart of this Agreement in the space provided for Seller's signature, and causing Agrifos to execute a counterpart of this Agreement in the space provided for Agrifos’ signature (Agrifos’ signature being a condition to Seller’s acceptance hereof and to the binding effectiveness of this Agreement), and delivering such Seller and Agrifos executed counterparts to the Title Company (in original signature form, or by telecopy/fax, or in PDF email file), then the offer evidenced by Purchaser’s execution and delivery of this Agreement (the “Offer”) shall automatically terminate and be deemed revoked; the parties acknowledge that Purchaser shall have the right to withdraw the Offer by written notice to Seller at any time prior to acceptance of this Agreement as aforesaid. It is a condition to the

effectiveness of this Agreement that Purchaser, Seller and Agrifos execute and deliver this Agreement. Contemporaneously with such acceptance by Seller, Seller shall send a copy of the fully executed Agreement to Purchaser. Immediately upon receipt of the fully executed Agreement by the Title Company, the Title Company shall receipt for same in the space provided below and promptly deliver a fully executed, receipted copy of this Agreement to Seller and one to Purchaser. This Agreement may be executed in multiple counterparts, each of which shall constitute an original but all of which shall together constitute one and the same Agreement. This Agreement may be accepted by delivery of original signatures, or by telecopy/fax transmission or PDF email file.

29.Industrial District Agreement. At Closing, the parties will indemnify each other for certain liabilities under the Industrial District Agreement as provided in the Indemnity Agreement. After Closing, Seller and Purchaser will cooperate with each other and will use good faith commercially reasonable efforts to obtain a partial Assignment and Assumption Agreement with respect to the Industrial District Agreement which is approved by the City of Houston and on the form prescribed by the Industrial District Agreement relating only to the Property, and to attempt to have the City of Houston agree not to charge payments in lieu of tax under the Industrial District Agreement with respect to portions of the Property that are already located within and being taxed by the City of Pasadena, Texas. Seller does not warrant or represent that such partial assignment or amendment of the Industrial District Agreement can be obtained but Seller and Purchaser will cooperate in all reasonable respects (including execution of disclosure and similar documentation as required by the City) in the effort of either party to obtain such approvals; provided that neither party shall be required to incur any out of pocket expense (except its own outside counsel attorney’s fees as it deems necessary) in pursuing such assignment, assumption and/or amendment of the Industrial District Agreement. The covenants and obligations of the parties contained in this Section shall survive Closing, but the covenant of cooperation shall continue only for a period ending on the earlier date of two years after Closing or the date that the aforesaid assignment and assumption is completed (or the date on which Purchaser enters into its own industrial district agreement with the City of Houston if sooner); provided, however, that if Purchaser’s continuing efforts (for up to the balance of the aforesaid 2 year cooperation period) to obtain the amendment referenced above after the assignment and assumption is completed, then Seller’s cooperation will continue during the balance of said 2 year period while Purchaser’s efforts continue, to the extent necessary in connection with any amendment of the Industrial District Agreement.

30.Agrifos Jointly Liable with Seller. Agrifos joins herein for purposes of agreeing and hereby agrees with Purchaser, as an agreement that survives Closing, that Agrifos is jointly and severally liable with Seller for all of Seller’s obligations and liabilities under this Agreement, including, but not limited to, liabilities and obligations for Seller’s breaches of and defaults under this Agreement and for which Seller remains responsible after Closing under the terms of this Agreement.
