     Re: Acquisition of Real Property Technologies, LLC (“RPT”) 


Dear Sam: 


     This letter confirms our understanding (“LOI”) in connection with the proposed purchase of 100% of the capital stock of Real Property Technologies, LLC. (“RPT”), a New York Limited Liability Company by International Smart Sourcing, Inc. (“ISSI”). 


1. Terms. ISSI agrees to purchase 100% of the issued and outstanding membership interest of RPT for the insurance of 40,000,000 shares of common stock of ISSI and 80 shares of Series C Preferred Stock of ISSI (the “Preferred Stock”). The Preferred Stock shall have a liquidation value of $100,000 per share. For five years, on the anniversary of issuance ISSI shall either redeem 16 of the preferred shares by paying the holder the liquidation value of such shares or by issuing the holders 3,200,000 shares of common stock. The option of redeeming for cash or by issuing shares shall be at ISSI’s sole discretion. (The issuance of the 40,000,000 shares of common stock and 80 shares of Series C Preferred Stock is referred to as the “Purchase Price”). ISSI’s purchase of the capital stock (the “Transaction”) in exchange for the Purchase Price hereunder
shall be subject to the completion of its due diligence review and the completion of RPT’s audited financial statements for the years ended December 31, 2006 and 2005 both of which shall be satisfactory to ISSI. RPT will own all of the capital stock of the subsidiaries listed on Schedule C hereto. 


2. Payment of Purchase Price. At the Closing of the Transaction, ISSI shall cause its transfer agent to issue the securities comprising the purchase price. 


3. Post-Acquisition Management Structure. Upon the closing of the Transaction, ISSI’s Board of Directors will be comprised of the three current directors of ISSI or its designees and three designees of RPT’s current controlling shareholders (the “RPT shareholders”). Michael Rakusin will be ISSI’s Chief Financial Officer. The executives identified on Schedule A hereto shall enter into employments agreements with ISSI. 


4. Post-Acquisition Capital Structure of ISSI. Following the closing of the Transaction, ISSI shall have an aggregate of 54,974,435 shares of common stock outstanding. Except for the Preferred Stock and the securities identified on Schedule B hereto, ISSI shall have no securities outstanding. 








5. Definitive Acquisition Agreement. ISSI, RPT and the RPT Insiders will prepare and sign a definitive acquisition agreement (the “Acquisition Agreement”) which agreement will contain customary representations and warranties. 


6. Liquidity. At the closing of the Transaction (the “Closing”), ISSI will have cash on hand and no liabilities other than those disclosed in its 10-Q for the quarter ended March 30, 2007 (or any subsequently filed financial statement filed under the Securities Exchange Act of 1934 as amended) those incurred in the ordinary course of business. ISSI will be current in all of their 1934 Act filings. 


7. No-Shop. 


	     	(a)	     	RPT and RPT Insiders (including any of their respective representatives, agents of affiliates) hereby agree, from that date hereof until October 31, 2007 that they will not enter into any discussions and/or negotiations pertaining to the acquisition of RPT or any of its affiliated subsidiaries with any other individual or entity.
