1.                                      Amendments.  The Credit Agreement is hereby amended as follows:

(a)                                 The first paragraph of the Recitals to the Credit Agreement is hereby deleted and replaced as follows:

Company has asked Wells Fargo to provide it with a $15,000,000.00 revolving line of credit (the “Line of Credit”) for working capital purposes and to facilitate the issuance of standby letters of credit.  Wells Fargo is agreeable to meeting Company’s request, provided that Company agrees to the terms and conditions of this Agreement.

Line of Credit and Limitations on Borrowing.  Wells Fargo shall make Advances to Company under the Line of Credit that, together with the L/C Amount, shall not at any time exceed in the aggregate the lesser of (i) $15,000,000.00 (the “Maximum Line Amount”), or (ii) the Borrowing Base limitations described in Section 1.2.  Within these limits, Company may periodically borrow, prepay in whole or in part, and reborrow.  Wells Fargo has no obligation to make an Advance during a Default Period or at any time Wells Fargo believes that an Advance would result in an Event of Default.

the date Company terminates the Line of Credit, or (iii) the date Wells Fargo terminates the Line of Credit following an Event of Default. (The earliest of these dates is the “Termination Date.”)

(d)                                 Section 1.2(a) of the Credit Agreement is hereby deleted and replaced as follows:

(a)                                 Borrowing Base.  The borrowing base (the “Borrowing Base”) is an amount equal to:

(i)                                     85% or such lesser percentage of Eligible Accounts as Wells Fargo in its sole discretion may deem appropriate; provided, that the percentage shall be 85% so long as the dilution of the Accounts is 5% or less, plus

(ii)                                  85% or such lesser percentage of Eligible Foreign Accounts (which are not more than 120 days past invoice date) as Wells Fargo in its sole discretion may deem appropriate, provided, that the percentage shall be 85% so long as the dilution of the Accounts is 5% or less or $5,000,000.00, whichever is less, plus

(iii)                               85% or such lesser percentage of the Net Orderly Liquidation Value of Eligible Inventory (consisting of finished goods or raw materials) as Wells Fargo in its sole discretion may deem appropriate, or $5,000,000.00, whichever is less, less

(iv)                              the Borrowing Base Reserve, less

(v)                                 Indebtedness (including amounts outstanding under letters of credit) that Company owes Wells Fargo that has not been advanced on the Revolving Note, less

(vi)                              Indebtedness that is not otherwise described in Section 1, including Indebtedness that Wells Fargo in its sole discretion finds on the date of determination to be equal to Wells Fargo’s net credit exposure with respect to any rate hedge agreement, derivative, foreign exchange, deposit, treasury management or similar transaction or arrangement extended to Company by Wells Fargo and any Indebtedness owed by Company to Wells Fargo Merchant Services, L.L.C.

Floating Rate Pricing

The “Floating Rate” for Line of Credit Advances = an interest rate equal to the sum of (i) Daily Three Month LIBOR, which interest rate shall change whenever Daily Three Month LIBOR changes, plus (ii) (a) three percent (3.0%) if the average excess availability under the Borrowing Base for the immediately preceding fiscal quarter was at least $7,500,000.00, or (b) three and one-half percent (3.5%) if the average excess availability under the Borrowing Base for the immediately preceding fiscal quarter was less than $7,500,000.00.  The Floating Rate will be adjusted on the first day of each fiscal quarter.

Company shall not transfer any part of its ownership interest in any Intellectual Property Rights, except as allowed pursuant to this Section 5.17, and shall not permit its rights as licensee of Licensed Intellectual Property to lapse, except that Company may transfer such rights or permit them to lapse if it has reasonably determined that such Intellectual Property Rights are no longer useful in its business. If Company transfers any Intellectual Property Rights for value (other than in connection with a Permitted Contract), Company shall pay the Proceeds to Wells Fargo for application to the Indebtedness. Company shall not license any other Person to use any of

Company’s Intellectual Property Rights, except that Company may grant licenses in the ordinary course of its business or as contemplated by the Permitted Contracts. Notwithstanding the above, and subject to the limitations detailed below, Wells Fargo hereby consents to the transactions detailed in the following contracts:

i)  So long as the Company receives not less than $100,000,000.00 in gross proceeds from the transaction, the Company shall be permitted to close the transaction evidenced by that certain Asset Purchase Agreement dated as of September 17, 2014 by and between the Company and SolAero Technologies Corp.

(k)                                 The following definitions are hereby added in Exhibit A of the Credit Agreement in the appropriate alphabetical order:

“Permitted Closing” means a Closing (as defined in either Permitted Contract).

“Permitted Contract” is defined in Section 5.17.

2.                                      No Other Changes.  Except as explicitly amended by this Amendment, all of the terms and conditions of the Credit Agreement shall remain in full force and effect and shall apply to any advance or letter of credit thereunder.

3.                                      Releases.  Effective automatically upon a Permitted Closing, which may be conclusively evidenced by the Company’s delivery to Wells Fargo of a certificate of an Officer of the Company stating that a Permitted Closing has occurred: (a) the Security Interest in the Collateral constituting Purchased Assets (as defined in the applicable Permitted Contract) or the release of which is contemplated by a Permitted Contract (the “Released Assets”) granted in favor of Wells Fargo shall automatically terminate and the Released Assets shall be released from any Liens granted by the Credit Agreement, the Negative Pledge, the Patent and Trademark Security Agreement, and any other Security Document then in effect; and (b) if all of the equity a Subsidiary of the Company is included in Released Assets, such Subsidiary shall automatically be released from any Loan Document to which it is then a party and from all

Notwithstanding anything in this Section 3 to the contrary, Wells Fargo and the Company agree that the forms of UCC amendments, termination statements, or releases attached hereto as Exhibit A, the Intellectual Property releases attached hereto as Exhibit B, and the form of the real estate related releases attached hereto as Exhibit C are all acceptable, and the Company or its designee is authorized to file applicable amendments, terminations, or releases in the form of Exhibits A through C upon the applicable Permitted Closing.

Notwithstanding anything in this Section 7 to the contrary, upon the effectiveness of this Amendment, Wells Fargo waives any Default or Event of Default under the Credit Agreement or any other Loan Document arising out of the transactions contemplated by the Permitted Contracts.

8.                                      Release.  The Company, and each Guarantor signing the Acknowledgment and Agreement of Guarantors set forth below, hereby absolutely and unconditionally releases and forever discharges Wells Fargo, and any and all participants, parent corporations, subsidiary corporations, affiliated corporations, insurers, indemnitors, successors and assigns thereof, together with all of the present and former directors, officers, agents and employees of any of the foregoing (each a “Released Party”), from any and all claims, demands or causes of action of any kind, nature or description, whether arising in law or equity or upon contract or tort or under any state or federal law or otherwise, which the Company or each Guarantor has had, now has or has made claim to have against any such

6

person for or by reason of any act, omission, matter, cause or thing whatsoever arising from the beginning of time to and including the date of this Amendment, whether such claims, demands and causes of action are matured or unmatured or known or unknown, except to the extent resulting from gross negligence, bad faith or willful misconduct or a material breach by a Released Party of the Credit Agreement or any other Loan Document, in each case, as determined by a final non-appealable judgment of a court of competent jurisdiction.
