The Offering

Common stock offered		1,923,931 shares
Common stock outstanding after the offering		22,130,499 shares

The Sky Ranch Note Acquisition

Effective July 30, 2010, we entered into a Loan Sale and Assignment Agreement (the “Agreement”) with the Bank of America, N.A. to acquire from Bank of America loan instruments secured by approximately 931 acres of land known as Sky Ranch. We are acquiring the promissory note payable by Sky Ranch, LLC (a wholly owned subsidiary of Neumann Homes, Inc.) and the deed of trust granted by Sky Ranch, LLC to secure the promissory note from Bank of America for a cash payment of $7.0 million. Concurrent with the signing of the Agreement, we made an escrow payment totaling $700,000 to Bank of America. The balance of the acquisition price, or $6.3 million, is due and payable upon closing, which is expected to be September 30, 2010. Effective September 28, 2010, we issued a convertible negotiable promissory note (the “Note”) to PAR Investment Partners, L.P. (“PAR”) an approximately 15% shareholder of Pure Cycle, in exchange for $5.2 million. The proceeds of the Note will be used to pay a portion of the purchase price due on the Sky Ranch Note acquisition. The remaining balance due is being raised in this offering.

Use of Proceeds		The proceeds of this offering from the sale of common stock by us, before expenses, will be approximately $5,771,800. The net proceeds will be used to pay a portion of the purchase price due on the Sky Ranch note acquisition and for working capital and other general corporate purposes, including acquisitions.
Risk Factors		An investment in the shares involves a high degree of risk. Please refer to “Risk Factors” beginning on page 4 of the accompanying prospectus for factors you should consider.

RECENT EVENTS

Effective September 28, 2010, we issued a convertible negotiable promissory note (the “Note”) to PAR Investment Partners, L.P. (“PAR”). The Note: (i) has a face value of $5.2 million, (ii) accrues simple interest at 10% per annum, (iii) interest from the issuance date of the Note through April 1, 2011 is due on April 1, 2011 with monthly interest payments due the first day of each month following April 1, 2011 until the Note matures on January 15, 2012, (iv) is unsecured, and (v) upon approval by our shareholders, will automatically be converted to unregistered common stock of Pure Cycle at a conversion price of the lower of (i) $2.70 per share and (ii) ninety percent (90%) of the price per share paid in this offering. The amount due pursuant to this Note agreement including interest would total approximately $5.4 million. We intend to seek shareholder approval to convert the Note to common stock at our 2011 annual meeting of shareholders. In conjunction with the Note, we granted PAR one demand right and piggyback rights to register the shares of common stock issuable upon conversion of the Note.

PAR currently owns approximately 15% of our outstanding common stock. PAR also intends to purchase shares of common stock in this offering. Upon completion of this offering and assuming the Note is converted into common stock, PAR will own approximately 29.6% of our common stock. Arthur G. Epker, III, an officer of a company controlling PAR currently serves on our board of directors. Mr. Epker abstained from voting on the approval by the board of both the Note and this offering.
