ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION
 
On January 25, 2006, the Company acquired Plaza Consulting Group, Inc. d/b/a Pharma Serv ("Pharma Serv"), from the Reporting Person pursuant to an Agreement and Plan of Reorganization ("Merger Agreement") effective as of January 25, 2006 by and among the Company, Plaza Acquisition Corp., a wholly-owned subsidiary of the Company, Pharma Serv and the Reporting Person, the sole stockholder of Pharma Serv. Pursuant to the Merger Agreement, the Reporting Person received 1,150,000 shares of the Company's common stock and other consideration in exchange for selling Pharma Serv.
 
On July 9, 2008, the Reporting Person purchased 466,667 Series C warrants issued by the Company from six warrant holders for an aggregate purchase price of $359,333 pursuant to a Purchase Agreement (as defined in Item 4). The Reporting Person exercised the 466,667 warrants on July 9, 2008 at an exercise price of $.7344 per share, with gross proceeds to the Company of $342,720.24.

On January 25, 2006 in connection with the Merger Agreement, Dov Perlysky, the Company's sole director at that time, elected Elizabeth Plaza, Kirk Michel, Irving Wiesen, and Howard Spindel as directors. Mr. Perlysky resigned as President and Elizabeth Plaza was appointed as the CEO of the Company.

In connection with the Merger Agreement, the Company sold 47 units to 42 accredited investors on January 25, 2006, each unit consisting of 25,000 shares of series A preferred stock, warrants to purchase 85,100 shares of common stock at $1.10 per share and warrants to purchase 85,100 shares of common stock at $1.65 per share (collectively, the "Investor Warrants"). On January 26, 2006, the Company filed a certificate of designation setting forth the rights of the holders of the Company's series A preferred stock, which provided that the series A preferred stock would automatically convert into shares of the Company's common stock when the Company filed an amendment to its certificate of incorporation. Furthermore, the Investors Warrants were not exercisable until the Company filed an amendment to its certificate of incorporation increasing its authorized shares of common stock.

On February 27, 2006, the Company's corporate name was changed from Lawrence Consulting Group, Inc. to Pharma-Bio Serv, Inc. with the filing certificate of merger merging the Company's wholly-owned subsidiary, Pharma-Bio Serv, Inc., into the parent entity. On April 25, 2006, the Company filed a restated certificate of incorporation with the Secretary of State of Delaware. The principal changes in the certificate of incorporation were: (a) an increase in the total number of shares of the Company's capital stock to sixty million (60,000,000) shares, of which ten million (10,000,000) shares are designated as Preferred Stock and fifty million (50,000,000) of which are designated as common stock, (b) authorization for the Board of Directors to issue preferred stock in one or more series, and specifying the terms and conditions of such issuance; and (c) a provision that upon the filing of the restated certificate of incorporation, each outstanding share of series A preferred stock was automatically converted into 13.616 shares of common stock, as provided in the certificate of designation creating the series A preferred stock.

Except as otherwise set forth in this Item 4, the Reporting Person has no present plans or proposals which relate to or would result in: (i) the acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; (ii) an extraordinary corporate transaction; such as a merger, reorganization or liquidation, involving the Company or any of its subsidiaries; (iii) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries; (iv) any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board of directors; (v) any material change in the present capitalization or dividend policy of the Company; (vi) any other material change in the Company's business or corporate structure; (vii) changes in the Company's Certificate of Incorporation, By-laws or instruments corresponding thereto or other actions which may impede the acquisition of control of the issuer by any person; (viii) causing a class of securities of the Company to cease to be quoted on Over the Counter Bulletin Board; (ix) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or (x) any action similar to any of those enumerated above.
