PRELIMINARY STATEMENTS

A.            Reference is made to the Third Amended and Restated Credit Agreement dated as of November 17, 2008 among the Borrowers, the Guarantors, the lenders party thereto and the Administrative Agent, as amended by the First Amendment dated as of March 11, 2009, the Second Amendment & Waiver dated as of May 15, 2009, the Third Amendment & Waiver dated as of May 29, 2009, the Fourth Amendment & Waiver dated as of June 8, 2009, the Fifth Amendment dated as of June 15, 2009, and the Sixth Amendment, Waiver & Consent dated as of July 31, 2009 (as amended through the date hereof, the “Credit Agreement”).  Unless otherwise expressly provided herein, capitalized terms used herein and not otherwise defined shall have the meanings assigned to such terms in the Credit Agreement.

B.            Section 7.01(m) of the Credit Agreement provides that a Trigger Event is an Event of Default.  It is a Trigger Event if on or prior to August 7, 2009, the Parent and MxEnergy fail to deliver (i) to the Administrative Agent, a letter from the Refinance Party confirming to the effect that the Refinance Party actively continues to negotiate definitive documentation in good faith with the Parent and the Borrowers on the Refinance Transaction and that the Refinance Party’s due diligence investigation of the Borrowers’ business has not identified any materially adverse matters in the judgment of the Refinance Party, (ii) to Bracewell & Giuliani LLP, the Commercial Term Sheet, (iii) to the Administrative Agent, a certificate from an authorized officer of the Parent certifying that the Commercial Term Sheet (y) evidences that any collateral to be provided to the Refinance Party in connection with the Refinance Transaction shall specifically exclude the LC Cash Collateral Account and the “Cash Collateral” (as defined in the Amended DACA (as defined in the Sixth Amendment)) and (z) enables a refinancing in full of the Obligations and permits MxEnergy to request the issuance of letters of credit in a face amount sufficient to enable the Borrowers to comply with Section 2.14(e)(ii), and (iv) to the Administrative Agent, a written agreement among the Refinance Party, the Parent and the Borrowers confirming that (x) such Commercial Term Sheet represents the agreement of such Persons as to the matters contained therein, (y) no other material matters in connection with the Senior Notes Exchange Offer or the Refinance Transaction remain outstanding as between such Persons, and (z) such Commercial Term Sheet is not inconsistent in any manner with the Equity & Intercreditor Term Sheets ((i)-(iv) collectively, the “August 7 Milestone Requirements”).  As of the date hereof, an Event of Default has occurred and is continuing under Section 7.01(m) of the Credit Agreement due to the failure of the Parent and MxEnergy to comply with the August 7 Milestone Requirements (the “Seventh Amendment Default”).

C.            The Borrowers have requested that the Lenders, the Issuing Bank and the Administrative Agent amend the Credit Agreement as set forth in this Amendment and waive the Seventh Amendment Default to the extent provided herein.

D.            The Lenders party hereto, constituting all of the Lenders under the Credit Agreement, the Issuing Bank and the Administrative Agent are willing to amend the Credit Agreement and waive the Seventh Amendment Default on the terms and conditions set forth herein.

Section 11.             Severability.  In case any provision in or obligation under this Amendment shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.
