NOW, THEREFORE, in consideration of the foregoing and the agreements, promises and covenants set forth below, and for other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

Section 1                                              Amendments to Loan Agreement.

“2.1 Security Interest.  To secure the payment and performance of all of the Obligations when due, Borrower hereby grants to ORIX a security interest in all of the following (collectively, the “Collateral”):  all right, title and interest of Borrower in and to its present and future assets of every kind, whether now owned or hereafter arising or acquired and wherever located, and all proceeds and products thereof, including without limitation the following: all Accounts; all Inventory; all Equipment; all General Intangibles (including without limitation all Intellectual Property and Deposit Accounts); all Investment Property; all Other Property; and any and all claims, rights and interests in any of the above, and all guaranties and security for any of the above, and all substitutions and replacements for, additions, accessions, attachments, accessories, and improvements to, and proceeds (including proceeds of any insurance policies, proceeds of proceeds and claims against third parties) of, any and all of the above, and all Borrower’s books relating to any of the above, including without limitation the assets identified in the Representations; provided, however, that the Collateral shall not include any assets that are the subject of any Permitted Acquisition to the extent that such assets are subject to a continuing security interest in favor of or otherwise pledged to the seller of such assets in connection with any deferred purchase consideration arrangement pursuant to such Permitted Acquisition and in connection with such Permitted Acquisition Borrower has provided ORIX with a schedule of such assets.”

(c)                                  Section 5.2 (Prepayment) of the Loan Agreement is hereby amended and restated in its entirety as follows:

“5.2 Prepayment.  Borrower shall have the option of prepaying the principal amount of the Loan, prior to the Maturity Date, in whole or in part, provided that Borrower concurrently pays ORIX (i) all accrued and unpaid interest on the principal so prepaid and (ii) a prepayment fee equal to 2.0% of the amount prepaid if prepayment occurs on or prior to the second anniversary of the Second Amendment Effective Date, and 1.0% of the amount prepaid if prepayment occurs after the second anniversary of the Second Amendment Effective Date and

on or before the third anniversary of the Second Amendment Effective Date.  Said prepayment fee shall be due from Borrower to ORIX upon any prepayment of the principal of the Loan, including without limitation any prepayment as a result of an Event of Default or the exercise of any rights or remedies by ORIX following the same. Prepayments of the Loan shall be applied pro rata to the principal installments due or outstanding on the Loan.”

(d)                                 Section 7 (Definitions) of the Loan Agreement is hereby amended by amending and restating the definitions of “Permitted Acquisition” and “Subordinated Debt” in their entirety as follows:

““Permitted Acquisition” means an acquisition transaction pursuant to which the following conditions are satisfied: (i) no Event of Default has occurred, is continuing or would exist after giving effect to such transactions; (ii) Borrower is in pro forma compliance with all financial covenants after giving effect to such transactions; (iii) such transaction does not result in a Change in Control (as applicable); (iv) Borrower is the surviving entity and the target is a U.S. entity or an entity organized under another jurisdiction within North America (including Mexico and countries located in the Caribbean) in which ORIX is able to perfect its liens in the acquired assets (as applicable); (v) the target becomes a borrower under this Agreement (as applicable); (vi) the merger or consolidation is not likely to cause a Material Adverse Change (as applicable); (vii) value of the acquired assets (inclusive of goodwill, but exclusive of any assets that are subject to a continuing security interest in favor of or otherwise pledged to the seller of such assets in connection with any deferred purchase consideration arrangement) is equal to or greater than the purchase price payment amount made at closing (exclusive of any deferred purchase price payment amounts or earn-out payments); (viii) acquired assets (other than any assets that are subject to a continuing security interest in favor of or otherwise pledged to the seller of such assets in connection with any deferred purchase consideration arrangement) become part of the Collateral, and are acquired free and clear of any other liens other than Permitted Liens; (ix) any Indebtedness used to finance deferred payment obligations shall not contain a cross-default to this Agreement and shall be Subordinated Debt; (x) Borrower provides ORIX copies of all final transaction documents related to such acquisition prior to closing; (xi) not later than ten (10) Business Days prior to the proposed acquisition consummation date, Borrower provides ORIX evidence that (a) the target is in a similar line of or complementary services business as Borrower; and (b) adequate financial information with respect to the seller and the seller’s assets to be acquired by Borrower; and (xii) for any acquisition with up-front consideration (exclusive of any deferred purchase price payment amounts or seller notes) greater than $15

““Subordinated Debt” means Indebtedness which is (i) on terms reasonably acceptable to ORIX in its Good Faith Business Judgment, and (ii) which is subordinated to the Obligations pursuant to (A) a Subordination Agreement in such form as ORIX shall reasonably specify in its Good Faith Business Judgment (which, among other terms, shall (unless otherwise agreed by ORIX) provide for a “silent-second” lien on the acquired assets in connection with any Permitted Acquisition if ORIX permits such Indebtedness to be secured by a lien), or (B) with respect to any deferred purchase consideration in an amount less than $4,000,000 in any Permitted Acquisition, the inclusion of the following provision in all agreements, notes, or documents evidencing such Indebtedness:

“[Seller] hereby acknowledges and agrees that [Seller]’s rights to receive any payment of the deferred portion of the Purchase Price (the “[Seller] Debt”), are unsecured with respect to the Collateral (as defined in the Loan Agreement (as defined below)) and subordinated to the payment in full in cash by [Buyer] of its obligations to ORIX Ventures, LLC (“ORIX”) under the Loan and Security Agreement dated as of October 7, 2011 (as the same may be further amended, restated, supplemented or replaced, the “ORIX Agreement”) by and between Quench USA, Inc. and ORIX (including the Obligations as defined in the ORIX Agreement,  collectively, the “ORIX Debt”).  Notwithstanding the foregoing, [Seller] may accept the regularly scheduled (non-default) payments of the deferred portion of the Purchase Price; provided that no default or event of default and no event which, with notice or passage of time or both, would constitute a default or event of default, has occurred under the ORIX Agreement, both before and after giving effect to such payments.

The [Seller] Debt shall not be cross-defaulted to the ORIX Debt.  Until the ORIX Debt has been paid and performed in full in cash, [Seller] shall not (i) accelerate the maturity of the [Seller] Debt, (ii) commence or join in any action or proceeding to recover any amounts due on the [Seller] Debt other than actions or proceedings in which recourse is limited to assets in which such [Seller] was granted a security interest in or which were otherwise pledged to [Seller] by [Buyer], (iii) commence or join in any involuntary bankruptcy petition, insolvency proceeding or similar judicial proceeding against [Buyer], or (iv) initiate or prosecute any claim, action or other proceeding (a) challenging the validity, enforceability or

4

unavoidability of any claim of ORIX with respect to any of its collateral, or (b) challenging the perfection, enforceability or unavoidability of any liens or security interests of ORIX in any collateral.

Notwithstanding any provision to the contrary contained in this Agreement, the parties hereto hereby acknowledge that ORIX is an intended third-party beneficiary of the foregoing subordination provisions and, until the ORIX Debt has been paid and performed in full in cash, the parties shall not amend or modify such provisions, without ORIX’s consent, and any purchaser, assignee or transferee of any rights, claim or interest of any kind in or to any of the [Seller] Debt, shall remain bound by the foregoing as a condition to any sale, assignment or transfer.”“
