Note 1: estimated debt outstanding as of 31 December 2011

1. Overview

The objective of the Transaction is to deleverage and rationalize GBA’s balance sheet and businesses in such a manner as to (i) benefit all of GBA’s existing stakeholders, (ii) retain the ‘good will’ reputation of GBA within the aerospace industry and at the United States Department of Defense and (iii) best position GBA to raise additional capital to further develop and exploit its technologies, all in the shortest time, at the lowest cost and with the most positive impact on GBA and its stakeholders going forward.

The Transaction will be effected through (a) the transfer of substantially all of GBA’s assets into one or more newly-created subsidiaries of GBA, Inc. (“Newcos”) and (b) the exchange of all Series B Preferred Stock Obligations, Secured Debt Obligations and Other Debt Obligations held by participating holders for beneficial ownership in Newcos in the aggregate amounts outlined in Section 4 below. Non-participating holders of Other Debt Obligations, and all other debt obligations of GBA, Inc., will be left intact as obligations of GBA, Inc. In addition, GBA, Inc. may be merged into a shell Delaware corporation, resulting in GBA, Inc. becoming a Delaware corporation.

2. Exchange/Rationalization of Balance Sheet

The exchange of all of the Series B Preferred Stock Obligations, Secured Debt Obligations and Other Debt Obligations held by participating holders will rationalize GBA’s balance sheet by eliminating approximately $170 million of debt obligations owed by GBA, thus allowing GBA to utilize free cash flow for its operations (including payment to trade creditors in the ordinary course of business) and to accomplish the restructuring contemplated hereby. In addition, it will result in a significantly cleaner balance sheet for GBA, thus opening the door for additional fundraising though private equity investments, an E5-B Immigration Program or a secondary public offering.

3. Organizational Structure

Following the exchange outlined in subparagraph (b) of Section 1 above, beneficial ownership of Newcos will be allocated among (i) GBA, Inc. (4% in the aggregate),

(ii) holders of Series B Preferred Stock Obligations and Secured Debt Obligations (approximately 70.38% in the aggregate, assuming participation in the exchange by all holders of Other Debt Obligations), (iii) participating holders of Other Debt Obligations (approximately 16.62% in the aggregate, assuming participation by all holders of Other Debt Obligations), and (iv) Management (9.0% in the aggregate).

4. Treatment of Stakeholders
