Pillar and Pillar GP expressly disclaim beneficial ownership of any shares of the Issuer’s common stock, par value $0.01 per share (the “Common Stock”), held directly by Mr. El Zein, and Mr. El Zein expressly disclaims beneficial ownership of any shares of Common Stock held directly by Pillar and indirectly by Pillar GP. Pillar directly holds (i) 1,124,260 shares of the Issuer’s Series D Convertible Preferred Stock (the “Preferred Stock”), which are convertible at any time, at the holder’s election, on a 1-for-5 basis (subject to adjustment and certain other limitations on conversion described below), into shares of Common Stock; and (ii) warrants (the “Warrants”) representing 2,810,650 shares of Common Stock, which are presently exercisable.

In addition, the terms of the Preferred Stock and the Warrants provide that the Issuer shall not effect (1) any conversion of Preferred Stock or (2) any exercise of Warrants, for a number of shares of Common Stock in excess of that number of shares of Common Stock which, upon giving effect to such conversion or exercise, as the case may be, would cause (a) the aggregate number of shares of Common Stock beneficially owned by Pillar and its affiliates to exceed 19.99% of the total number of issued and outstanding shares of Common Stock of the Issuer as of the Closing Date, or (b) the combined voting power of the securities of the Issuer beneficially owned by Pillar and its affiliates to exceed 19.99% of the combined voting power of all of the securities of the Issuer outstanding as of the Closing Date. Accordingly, the 5,524,114 shares of Common Stock reported above represent 19.99% of the 27,634,389 shares of Common Stock outstanding as of the Closing Date (as defined below).

Standstill
The Purchase Agreement provides that, for so long as the total number of shares of Common Stock beneficially owned by Pillar and its affiliates exceeds 15% of the then outstanding shares of Common Stock, neither Pillar nor its affiliates will, directly or indirectly (unless specifically invited in writing by the Issuer to do so):

(e) enter into any agreements, discussions or arrangements with any third party with respect to any of the foregoing.
This standstill provision shall not restrict Pillar’s ability to exercise its preemptive rights as more fully described below under the heading “Preemptive Rights”.
Voting
On any matter presented to the stockholders of the Issuer for their action or consideration at any meeting of stockholders of the Corporation, each holder of outstanding shares of Preferred Stock shall be entitled to cast a number of votes equal to the number of whole shares of Common Stock into which the shares of Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter.
The Purchase Agreement provides that, for so long as the total number of shares of Common Stock beneficially owned by Pillar and its affiliates exceeds 15% of the then outstanding shares of Common Stock, in any election of directors and in any other vote to be taken by the stockholders of the Issuer (whether taken at an annual or special meeting of stockholders or by written action), Pillar and its affiliates will vote such number of shares of Common Stock beneficially owned by Pillar and its affiliates in excess of 15% in the same manner as, and in the same proportion to, the votes cast by the other holders of the Company’s Common Stock or other voting securities.
Preemptive Rights
The Purchase Agreement provides that, in the event the Issuer on or prior to the earlier of (i) November 4, 2014 and (ii) the day that Pillar holds a number of shares of Preferred Stock (including shares of Common Stock issued upon conversion of the Preferred Stock) which is less than 50% of the number of shares of Preferred Stock purchased by Pillar, proposes to:
(a) privately sell and issue securities of the Issuer, Pillar shall have the option to purchase, on the same terms and conditions offered by the Issuer to the other purchasers of such securities in such additional financing, up to that percentage of the securities sold in such additional financing equal to (A) the number of shares then held by Pillar as compared to (B) the total number of shares then outstanding, which pro rata amount shall not exceed 19.99% of such additional financing or

(b) enter into a loan financing for the purpose of raising capital and not for the purpose of purchasing equipment, or privately sell and issue convertible debt securities or preferred stock of the Issuer that ranks senior to the Preferred Stock, Pillar shall have the option to participate in such loan financing or other senior financings, on the same terms and conditions offered by the Issuer to the other participants or purchasers of securities in such senior financings, up to that percentage of the amount of the loan financing or of the securities sold in such senior financing equal to the product of:
(I) A fraction, the numerator of which equals the number of shares then held by Pillar and the denominator of which equals the total number of shares issued to Pillar; and
(II) If the closing date of the senior financing is on or prior to (i) November 4, 2012, 50%, (ii) November 4, 2013, 40%, or (iii) November 4, 2014, 30%.
Registration Rights Agreement
In connection with the Purchase Agreement, Pillar entered into a Registration Rights Agreement, dated November 4, 2011 (the “Registration Rights Agreement”), with the Issuer. The Registration Rights Agreement provides that the Company will file a resale registration statement (the “Resale Registration Statement”) covering the shares of Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants. The Issuer agreed to use its reasonable best efforts to cause to become effective the Resale Registration Statement on or prior to February 2, 2012.
If (i) the Resale Registration Statement is not declared effective on or before March 4, 2012 or (ii) after the Resale Registration Statement has been declared effective, sales of any of the Registrable Securities (as defined in the Registration Rights Agreement) cannot be made pursuant to such Resale Registration Statement because such Resale Registration Statement has been suspended (except as a result of a permitted suspension as provided in the Registration Rights Agreement), then the Issuer shall pay to Pillar an amount equal to the product of (A) the aggregate purchase price of the Preferred Stock then held by Pillar, multiplied by (B) one hundredths (.01), for each thirty (30) day period thereafter. Notwithstanding the foregoing, in no event shall the Issuer be obligated to make payments to Pillar in an aggregate amount that exceeds 10% of the aggregate purchase price paid by Pillar for the Preferred Stock.
The Issuer will pay all registration expenses, other than underwriting discounts and commissions, related to the Issuer’s performance of the Registration Rights Agreement. The Registration Rights Agreement contains customary cross-indemnification provisions.
The foregoing descriptions of the Purchase Agreement and the Registration Rights Agreement and of the terms the Certificate of Designations, Preferences and Rights of the Preferred Stock and the Form of Warrant issued to Pillar (collectively, the “Transaction Documents”) do not purport to be complete and are qualified in their entirety by the terms of each such document, which are attached hereto as Exhibit 2, Exhibit 3, Exhibit 4 and Exhibit 5, respectively, and are incorporated herein by reference.
