     This Amendment No. 4 hereby amends and supplements the statement of beneficial ownership on Schedule 13D, relating to the common stock, par value $0.001 per share (the “Common Stock”), of Averion International Corp., a Delaware corporation (the “Issuer” or “Averion”), initially filed on November 21, 2005, as amended by Amendment No. 1 thereto filed on January 13, 2006, Amendment No. 2 thereto filed on September 13, 2006 and Amendment No. 3 thereto filed on November 8, 2007 (as so amended, the “Schedule 13D”). All capitalized terms not otherwise defined herein have the meaning assigned to them in the Schedule 13D. Unless specifically amended hereby, the disclosures set forth in the Schedule 13D shall remain unchanged.

Item 3. Source and Amount of Funds or Other Consideration.

     Item 3 of the Schedule 13D is hereby amended and supplemented by adding the following:

     On June 1, 2007, the Issuer granted an option (the “Option”) to purchase 1,500,000 shares of the Issuer’s Common Stock to Mr. Falk. The Option vests in four equal 25% increments. The first 25% increment vested on June 1, 2008 and the remaining increments vest on the second, third and fourth anniversaries of the grant date. Mr. Falk may be deemed to beneficially own the shares of Common Stock underlying the unvested portion of the Option solely for purposes of Section 16 of the Securities Exchange Act of 1934, as amended.

     On June 27, 2008, as part of a debt financing transaction (the “Financing Transaction”), the Issuer entered into a securities purchase agreement pursuant to which it agreed to sell senior secured notes in the aggregate principal amount of $2,000,000 (the “Notes”) and issue an aggregate of 9,600,000 shares of the Issuer’s Common Stock to two investors (the “Investors”). On June 27, 2008, ComVest Investment Partners II, LLC, one of the Investors, purchased a Note in the principal amount of $1,000,000 and received 4,800,000 shares of the Issuer’s Common Stock. The Notes bear interest, payable quarterly in arrears, at the rate of 3% through October 31, 2008, 10% through October 31, 2009 and 15% through October 31, 2010. The Notes are prepayable at any time and become fully due and payable on October 31, 2010. The Notes are senior in right of payment to all other indebtedness of the Company except that they are pari passu to the senior secured notes issued by the Company in October and November 2007 in the aggregate principal amount of $26,000,000.
