RECITALS

A. Pursuant to the Comprehensive Amendment Agreement No. 1, dated as of April 11, 1996 (the “CAA”), between Pure Cycle and certain investors (including CAA Holder), Pure Cycle is obligated to pay such investors certain proceeds it receives from the sale of “Export Water” (as defined in the CAA).

B. CAA Holder is referenced in Section 2.1(i), (r), and (t)(i) of the CAA and is entitled to receive “Gross Proceeds” (as defined in the CAA) totaling $350,000, $286,995, and $413,005, respectively, under these subsections of the CAA (collectively, the “CAA Holder Gross Proceeds”).

C. Pure Cycle has offered to purchase from the CAA Holder all of its rights to receive payments under the CAA at a discount to the face amount of the CAA Holder Gross Proceeds in consideration of the issuance of certain shares of the capital stock of Pure Cycle, and CAA Holder has accepted the offer, on and subject to the terms set forth herein.

AGREEMENT

In consideration of the mutual promises herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

1. Purchase and Sale of CAA Interest. CAA Seller hereby unconditionally and irrevocably sells, transfers, assigns and conveys to Pure Cycle, and Pure Cycle hereby purchases and accepts from CAA Holder, all of its right, title and interest in and to CAA, including without limitation: (i) the right of CAA Holder to receive monies and other property or assets due and to become due to the CAA Holder pursuant to the CAA (including, without limitation, the CAA Holder Gross Proceeds) and (ii) all rights of the CAA Holder to compel performance and otherwise exercise all remedies thereunder (collectively, the “Transferred Interest”). Pure Cycle hereby assumes all of the obligations, liabilities, responsibilities and commitments of the CAA Holder under the CAA.

2. Purchase Price. In consideration of the sale of the Transferred Interests, Pure Cycle hereby agrees to issue and deliver 47,398 shares of common stock of Pure Cycle (the “PC Shares”) to CAA Holder. The PC Shares shall bear the legend restricting transfer set forth in Section 8 hereof.

3. Effect of Purchase. Upon issuance to the CAA Holder of the PC Shares, all rights of the CAA Holder relating in any way to the CAA will be owned by Pure Cycle. Pure Cycle and CAA Holder agree that this Agreement constitutes an assignment to Pure Cycle of all of the CAA Holder’s rights, title and interest in and to the CAA as of the date hereof, and that as of the date hereof the CAA Holder shall cease to possess any rights with respect to the CAA.

4. Representations and Warranties of the CAA Holders.

(a) Authority. The CAA Holder represents that it has all requisite right, power, and authority to execute, deliver and perform its obligations under this Agreement; this Agreement has been duly and validly authorized, executed and delivered by the CAA Holder; and this Agreement is the valid and binding obligation of the CAA Holder, enforceable against it in accordance with its terms, except as enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent conveyance, redemption, reinstatement, and other laws affecting the rights or remedies of creditors generally or (ii) general principles of equity.

(b) Ownership. The Transferred Interest represents the entire interest of the CAA Holder under the CAA. The CAA Holder owns the Transferred Interest and passes to Pure Cycle good and marketable title to the Transferred Interest, free and clear of any lien, encumbrance, pledge, option, adverse interest, charge or assessment of any kind (a “Lien”). The CAA holder represents that it has not taken any action to sell or otherwise transfer the Transferred Interest, to mortgage, hypothecate or otherwise encumber the Transferred Interest, or to grant any Lien on the incidents of ownership of the Transferred Interest, including any right of first offer or other contractual obligation.

(c) No Conflicts. The CAA Holder represents that the execution, delivery and performance by it of this Agreement does not and will not (i) conflict with, violate, result in a breach of or constitute a default under any agreement, instrument or obligation to which such CAA Holder is a party or by which it is bound; (ii) conflict with or violate any order, judgment, decree, statute, rule or regulation applicable to the CAA Holder; (iii) result in the creation or imposition of any Lien against or upon the Transferred Interest; or (iv) require any consent, approval or authorization of, or filing with, any governmental authority or any other third party.

(d) Investment Representations. The CAA Holder understands that the valuation of interests in the CAA and the common stock of Pure Cycle is uncertain and that such value derives significantly from future transactions and developments that are largely unknown and unknowable. The CAA Holder acknowledges that the consideration being paid hereunder represents the result of an arms’ length negotiation between Pure Cycle and the CAA Holder and represents the fair market value of the Transferred Interest. The CAA Holder has read and understands the public filings made by Pure Cycle with the U.S. Securities and Exchange Commission (the “SEC”). In addition, the CAA Holder has been given the opportunity to solicit from Pure Cycle all information relevant to valuation of rights under the CAA and regarding Pure Cycle’s business and operations and has received all the information requested. The CAA Holder has made an investigation of the pertinent facts related to Pure Cycle, the PC Shares, and the likelihood of payment under the CAA and has reviewed all information regarding Pure Cycle to the extent it deems necessary in order to be fully informed with respect thereto. The CAA Holder is an “accredited investor” within the meaning of Rule 501 under the Securities Act of 1933, as amended (the “Securities Act”), and is knowledgeable and experienced in securities, financial and business matters and in transactions of this nature, and has made its own assessment of the value of the PC Shares and of its rights under the CAA. The CAA Holder is capable of evaluating the merits and risks of this transaction and is able to bear a complete loss of the investment in the PC Shares. The CAA Holder understands that subsequent events may prove that values of interests in the CAA were higher or lower than the valuation indicated by the PC Shares paid hereunder.

(e) Restricted Stock. The CAA Holder represents that it has been advised and understands that the PC Shares have not been registered under the Securities Act or any state securities laws and that the PC Shares are being issued in reliance upon exemptions from such registration requirements. The CAA Holder acknowledges that the PC Shares are “restricted securities” as that term is defined in Rule 144 promulgated by the SEC under the Securities Act and may not be sold or transferred by the CAA Holder unless such PC Shares are subsequently registered under that act and applicable state securities laws or are transferred pursuant to an exemption from such registration requirements.

5. Representations and Warranties of Pure Cycle.

(a) Authority. Pure Cycle has all corporate right, power, and authority to execute, deliver and perform its obligations under this Agreement. This Agreement has been duly and validly authorized, executed and delivered by Pure Cycle.

(b) No Conflicts. The execution, delivery and performance by Pure Cycle of this Agreement does not and will not (i) conflict with, violate, result in a breach of or constitute a default under any agreement, instrument or obligation to which Pure Cycle is a party or by which Pure Cycle is bound; (ii) conflict with or violate any order, judgment, decree, statute, rule or regulation applicable to Pure Cycle; or (iii) except as required by Form 8-K under the Securities and Exchange Act of 1934, require any consent, approval or authorization of, or filing with, any governmental agency.

Pure Cycle, on behalf of itself and its officers, directors, employees and agents, hereby fully and forever releases and discharges the CAA Holder and its partners, officers, agents, employees, affiliates, successors and predecessors from any and all claims, demands, proceedings, causes of actions, orders, obligations, contracts, agreements, debts, guarantees, damages, expenses, costs, attorneys’ fees and liabilities whatsoever, whether known or unknown, suspected or unsuspected, both at law and in equity, which Pure Cycle now has, has ever had or may hereafter have against the CAA Holder in connection with, related to or arising out of (i) the CAA Holder’s interest in the CAA and (ii) the financing transactions pursuant to which Pure Cycle entered into the CAA.
