EXHIBIT 10.34

REVOLVING LINE OF CREDIT NOTE

FOR VALUE RECEIVED, the undersigned U.S. HOME SYSTEMS, INC. (“Borrower”) promises to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION (“Bank”) at its office at 4975 Preston Park Blvd, Suite 280, Plano, TX 75093, or at such other place as the holder hereof may designate, in lawful money of the United States of America and in immediately available funds, the principal sum of Two Million Five Hundred Thousand Dollars ($2,500,000.00), or so much thereof as may be advanced and be outstanding, with interest thereon, to be computed on each advance from the date of its disbursement as set forth herein.

DEFINITIONS:

As used herein, the following terms shall have the meanings set forth after each, and any other term defined in this Note shall have the meaning set forth at the place defined:

(a) “Business Day” means any day except a Saturday, Sunday or any other day on which commercial banks in Texas are authorized or required by law to close.

(b) “Daily One Month LIBOR” means, for any day, the rate of interest equal to LIBOR then in effect for delivery for a one (1) month period.

(c) “LIBOR” means the rate per annum (rounded upward, if necessary, to the nearest whole 1/8 of 1%) and determined pursuant to the following formula:

(i) “Base LIBOR” means the rate per annum for United States dollar deposits quoted by Bank as the Inter-Bank Market Offered Rate, with the understanding that such rate is quoted by Bank for the purpose of calculating effective rates of interest for loans making reference thereto, for delivery of funds for one (1) month in an amount equal to the outstanding principal balance of this Note. Borrower understands and agrees that Bank may base its quotation of the Inter-Bank Market Offered Rate upon such offers or other market indicators of the Inter-Bank Market as Bank in its discretion deems appropriate including, but not limited to, the rate offered for U.S. dollar deposits on the London Inter-Bank Market.

(ii) “LIBOR Reserve Percentage” means the reserve percentage prescribed by the Board of Governors of the Federal Reserve System (or any successor) for “Eurocurrency Liabilities” (as defined in Regulation D of the Federal Reserve Board, as amended), adjusted by Bank for expected changes in such reserve percentage during the applicable term of this Note.

INTEREST:

(a) Interest. The outstanding principal balance of this Note shall bear interest (computed on the basis of a 360-day year, actual days elapsed, unless such calculation would result in a usurious rate, in which case interest shall be computed on the basis of a 365/366-day year, as the case may be, actual days elapsed) at the lesser of (i) a fluctuating rate per annum

-1-

determined by Bank to be two and three quarters percent (2.75%) above Daily One Month LIBOR in effect from time to time, or (ii) the Maximum Rate. Each change in the rate of interest hereunder shall become effective on each Business Day a change in Daily One Month LIBOR is announced within Bank. Bank is hereby authorized to note the date and interest rate applicable to this Note and any payments made thereon on Bank’s books and records (either manually or by electronic entry) and/or on any schedule attached to this Note, which notations shall be prima facie evidence of the accuracy of the information noted.

(b) Taxes and Regulatory Costs. Borrower shall pay to Bank immediately upon demand, in addition to any other amounts due or to become due hereunder, any and all (i) withholdings, interest equalization taxes, stamp taxes or other taxes (except income and franchise taxes) imposed by any domestic or foreign governmental authority and related in any manner to LIBOR, and (ii) future, supplemental, emergency or other changes in the LIBOR Reserve Percentage, assessment rates imposed by the Federal Deposit Insurance Corporation, or similar requirements or costs imposed by any domestic or foreign governmental authority or resulting from compliance by Bank with any request or directive (whether or not having the force of law) from any central bank or other governmental authority and related in any manner to LIBOR to the extent they are not included in the calculation of LIBOR. In determining which of the foregoing are attributable to any LIBOR option available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower.

(c) Payment of Interest. Interest accrued on this Note shall be payable on the 22nd day of each month, commencing September 22, 2011.

(d) Default Interest. From and after the maturity date of this Note, or such earlier date as all principal owing hereunder becomes due and payable by acceleration or otherwise, or at Bank’s option upon the occurrence, and during the continuance of an Event of Default, the outstanding principal balance of this Note shall bear interest (computed on the basis of a 360-day year, actual days elapsed, unless such calculation would result in a usurious rate, in which case interest shall be computed on the basis of a 365/366-day year, as the case may be, actual days elapsed) at an increased rate equal to the lesser of (i) a rate per annum equal to four percent (4%) above the rate of interest from time to time applicable to this Note, or (ii) the Maximum Rate.

BORROWING AND REPAYMENT:

(a) Borrowing and Repayment. Borrower may from time to time during the term of this Note borrow, partially or wholly repay its outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions of this Note and of any document executed in connection with or governing this Note; provided however, that the total outstanding borrowings under this Note shall not at any time exceed the principal amount stated above. The unpaid principal balance of this obligation at any time shall be the total amounts advanced hereunder by the holder hereof less the amount of principal payments made hereon by or for Borrower, which balance may be endorsed hereon from time to time by the holder. The outstanding principal balance of this Note shall be due and payable in full on August 22, 2014.

(b) Advances. Advances hereunder, to the total amount of the principal sum stated above, may be made by the holder at the oral or written request of (i) Murry H. Gross or Robert A. Defronzo, any one acting alone, who are authorized to request advances and direct the disposition of any advances until written notice of the revocation of such authority is received by

-2-

the holder at the office designated above, or (ii) any person, with respect to advances deposited to the credit of any deposit account of Borrower, which advances, when so deposited, shall be conclusively presumed to have been made to or for the benefit of Borrower regardless of the fact that persons other than those authorized to request advances may have authority to draw against such account. The holder shall have no obligation to determine whether any person requesting an advance is or has been authorized by Borrower.

(c) Application of Payments. Each payment made on this Note shall be credited first, to any interest then due and second, to the outstanding principal balance hereof.

EVENTS OF DEFAULT:

This Note is made pursuant to and is subject to the terms and conditions of that certain Credit Agreement between Borrower and Bank dated as of August 22, 2011, as amended from time to time (the “Credit Agreement”). Any default in the payment or performance of any obligation under this Note, or any defined event of default under the Credit Agreement, shall constitute an “Event of Default” under this Note.

MISCELLANEOUS:

(a) Remedies. Upon the occurrence of any Event of Default, the holder of this Note, at the holder’s option, may declare all sums of principal and accrued and unpaid interest outstanding hereunder to be immediately due and payable without presentment, demand, or any notices of any kind, including without limitation notice of nonperformance, notice of protest, protest, notice of dishonor, notice of intention to accelerate or notice of acceleration, all of which are expressly waived by Borrower, and the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Borrower shall pay to the holder immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including reasonable attorneys’ fees (to include outside counsel fees and all allocated costs of the holder’s in-house counsel to the extent permissible), expended or incurred by the holder in connection with the enforcement of the holder’s rights and/or the collection of any amounts which become due to the holder under this Note, and the prosecution or defense of any action in any way related to this Note, including without limitation, any action for declaratory relief, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other person) relating to Borrower or any other person or entity.

(b) Obligations Joint and Several. Should more than one person or entity sign this Note as a Borrower, the obligations of each such Borrower shall be joint and several.

(c) Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of Texas.

(d) Savings Clause. It is the intention of the parties to comply strictly with applicable usury laws. Accordingly, notwithstanding any provision to the contrary in this Note, or in any contract, instrument or document evidencing or securing the payment hereof or otherwise relating hereto (each, a “Related Document”), in no event shall this Note or any Related Document require the payment or permit the payment, taking, reserving, receiving, collection or charging of any sums constituting interest under applicable laws that exceed the maximum amount permitted by such laws, as the same may be amended or modified from time to time

-3-

(the “Maximum Rate”). If any such excess interest is called for, contracted for, charged, taken, reserved or received in connection with this Note or any Related Document, or in any communication by Bank or any other person to Borrower or any other person, or in the event that all or part of the principal or interest hereof or thereof shall be prepaid or accelerated, so that under any of such circumstances or under any other circumstance whatsoever the amount of interest contracted for, charged, taken, reserved or received on the amount of principal actually outstanding from time to time under this Note shall exceed the Maximum Rate, then in such event it is agreed that: (i) the provisions of this paragraph shall govern and control; (ii) neither Borrower nor any other person or entity now or hereafter liable for the payment of this Note or any Related Document shall be obligated to pay the amount of such interest to the extent it is in excess of the Maximum Rate; (iii) any such excess interest which is or has been received by Bank, notwithstanding this paragraph, shall be credited against the then unpaid principal balance hereof or thereof, or if this Note or any Related Document has been or would be paid in full by such credit, refunded to Borrower; and (iv) the provisions of this Note and each Related Document, and any other communication to Borrower, shall immediately be deemed reformed and such excess interest reduced, without the necessity of executing any other document, to the Maximum Rate. The right to accelerate the maturity of this Note or any Related Document does not include the right to accelerate, collect or charge unearned interest, but only such interest that has otherwise accrued as of the date of acceleration. Without limiting the foregoing, all calculations of the rate of interest contracted for, charged, taken, reserved or received in connection with this Note and any Related Document which are made for the purpose of determining whether such rate exceeds the Maximum Rate shall be made to the extent permitted by applicable laws by amortizing, prorating, allocating and spreading during the period of the full term of this Note or such Related Document, including all prior and subsequent renewals and extensions hereof or thereof, all interest at any time contracted for, charged, taken, reserved or received by Bank. The terms of this paragraph shall be deemed to be incorporated into each Related Document.

To the extent that either Chapter 303 or 306, or both, of the Texas Finance Code apply in determining the Maximum Rate, Bank hereby elects to determine the applicable rate ceiling by using the weekly ceiling from time to time in effect, subject to Bank’s right subsequently to change such method in accordance with applicable law, as the same may be amended or modified from time to time.

(e) Right of Setoff; Deposit Accounts. If an Event of Default shall have occurred and be continuing, the Bank is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by the Bank to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Note held by the Bank, irrespective of whether or not the Bank shall have made any demand under this Note and although such obligations may be unmatured. The rights of the Bank under this Section are in addition to other rights and remedies the Bank may have.

(f) Business Purpose. Borrower represents and warrants that all loans evidenced by this Note are for a business, commercial, investment, agricultural or other similar purpose and not primarily for a personal, family or household use.

(g) Certain Tri-Party Accounts. Borrower and Bank agree that Chapter 346 of the Texas Finance Code (which regulates certain revolving credit accounts and revolving triparty accounts) shall not apply to any revolving loan accounts created under this Note or maintained in connection herewith.
