This Forbearance Agreement ("Agreement") is entered into effective as of January 3, 2011, by and between WB QT, LLC, a Delaware limited liability company for itself and as agent for the Lenders (the "Senior Lenders") and Quantum Fuel Systems Technologies Worldwide, Inc., a Delaware corporation (the "Borrower").                

1. The WB QT, LLC, as Agent and other Lenders entered into a Credit Agreement dated as of January 31, 2007 (such Credit Agreement, together with all amendments, the "Credit Agreement").
2. The Borrower is indebted to the Senior Lenders under certain convertible promissory notes each issued on April 30, 2010 (collectively, together with all amendments, the "Convertible Notes").
3. The Borrower is indebted to the Senior Lenders under a certain Amended and Restated Term B Note issued on May 30, 2008 (the "Term Note B").
4. The Borrower is indebted to the Senior Lenders under a certain Term Note dated November 24, 2009 (the "Consent Fee Term Note").
5. The Convertible Notes, the Term Note B and the Consent Fee Term Note are sometimes collectively referred to herein as the "Senior Promissory Notes" and the Senior Promissory Notes together with the Credit Agreement and all other agreements, certificates, and documents executed and delivered by Borrower in connection therewith and all amendments and modifications thereto are collectively referred to herein as the "Senior Loan Documents".
6. All indebtedness and other sums evidenced by any of the Senior Promissory Notes or owing to Lender under any of the Senior Loan Documents shall collectively be referred to herein as the "Senior Indebtedness".
7. On August 3, 2009, the Borrower and Whitebox Advisors, LLC ("Whitebox"), an affiliate of the Senior Lenders, entered into an unconditional commitment letter pursuant to which Whitebox agreed to provide further investments in the Borrower, not to exceed $10,000,000, at the option and request of the Borrower (such commitment letter, together with all amendments, the "Original Commitment").
8. On January 3, 2011, for good and valuable consideration the Borrower and Whitebox agreed to terminate the Original Commitment and amend the Credit Agreement to create a new $5,000,000 loan facility pursuant to which Senior Lenders commit to loan Borrower up to $5,000,000 (the "New Facility").
9. On October 13, 2010 and October 19, 2010 the Borrower issued senior subordinated promissory notes (collectively, the "Bridge Notes") in connection with the closing of a private placement transaction with certain accredited investors, which Bridge Notes have a scheduled maturity date of December 31, 2010 (the "Bridge Note Maturity Date").
10. The Borrower anticipates that it will not have sufficient cash on hand to pay the indebtedness owed under the Bridge Notes on the Bridge Note Maturity Date, which failure to pay on the Bridge Note Maturity Date shall constitute an Event of Default under the Bridge Notes ("Bridge Notes Default").
11. Under the terms of the Senior Loan Documents, a Bridge Notes Default constitutes a cross default or event of default under the Senior Loan Documents (the "Specified Default").
12. The Borrower has requested that the Senior Lenders agree to forbear, and the Senior Lenders have agreed to forbear, from exercising their rights and remedies with respect to any Specified Default during the Forbearance Period (as defined below) should any Specified Default be determined to have actually occurred, on the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the above recitals, the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and adequacy of which are hereby mutually acknowledged, the parties covenant and agree as follows:

1. Acknowledgement and Reaffirmation.  The Borrower hereby acknowledges and agrees that:

1. (i) the Borrower together with any of Borrower's subsidiaries and affiliates that are parties to any of the Senior Loan Documents (collectively the "Loan Parties") are indebted and liable to the Senior Lenders in the aggregate amount of $20,612,641 as of October 31, 2010 in respect to the Senior Loan Documents inclusive of principal, interest, fees, expenses (including but not limited to attorneys', advisors' and consultants' fees that are reimbursable under the Senior Loan Documents) , and such amounts outstanding under the Senior Loan Documents constitute valid and subsisting obligations of the Borrower to the Senior Lenders that are not subject to any credits, offsets, defenses, claims, counterclaims or adjustments of any kind. The Borrower hereby (i) acknowledges and affirms its obligations under the respective Senior Loan Documents to which it is a party, (ii) acknowledges and affirms the liens created and granted by the Loan Parties in the Senior Loan Documents and (iii) agree that, other than as expressly set forth herein, this Agreement shall in no manner adversely affect or impair such obligations and/or liens; and

2. Forbearance.  Subject to the terms and conditions set forth herein, from the date this Agreement is fully executed and delivered by the parties (the "Effective Date") through the earlier of (a) the date on which the Loan Parties fail to comply with the covenants contained in Section 7 of this Agreement, (b) the date of the commencement by the Borrower of a voluntary bankruptcy, insolvency, reorganization or other similar proceeding or the commencement of any similar non-voluntary case or proceeding with respect to the Borrower that remains undismissed or stayed for a period of 30 days following the date of filing, and (c) 12:00 noon (EST) on April 30, 2011 (the "Forbearance Period"), the Senior Lenders hereby agree to forbear from exercising any and all rights or remedies available under the Senior Loan Documents or applicable law as a result of the Specified Defaults, but only to the extent that such rights and remedies arise solely as a result of the occurrence and continuation of the Specified Defaults; provided, however, that in each case, the Senior Lenders shall be free to exercise any or all rights and remedies arising on account of any Specified Default at the end of the Forbearance Period; provided further, that except as expressly set forth herein, this Agreement shall not operate as a waiver, amendment or modification of the Senior Loan Documents. Notwithstanding anything contained in the Senior Loan Documents or this Agreement to the contrary, the Borrower will be entitled to repay the Bridge Notes (other than with proceeds from the New Facility) during the Forbearance Period and that upon such repayment of the Bridge Notes, the Specified Default will be deemed cured and the Senior Lenders will not be entitled to exercise any rights or remedies by virtue of the Specified Default following the expiration of the Forbearance Period.

3. No Waiver of Rights or Remedies.  The Senior Lenders and the Loan Parties agree that, other than as expressly set forth herein, nothing in this Agreement, or the performance by the Senior Lenders of their obligations hereunder, constitutes or shall be deemed to constitute a waiver of any of the rights or remedies available to the Senior Lenders or the Loan Parties under the Senior Loan Documents or any applicable law, all of which are hereby reserved. 

4. Representations and Warranties of the Loan Parties.  The Loan Parties hereby represent and warrant to the Senior Lenders that:
