This Amendment No. 1 to Credit Agreement and Consent (this “Amendment”) is entered into as of November 7, 2012 by and among Monitronics International, Inc., a Texas corporation (“Borrower”), Bank of America, N.A., individually and as administrative agent (the “Administrative Agent”), and the other financial institutions signatory hereto.

RECITALS

A.                                    Borrower, the Administrative Agent and the Lenders are party to that certain Credit Agreement dated as of March 23, 2012 (the “Credit Agreement”).

B.                                    Borrower wishes to borrow $145,000,000 from Bank of America, N.A. (the “Incremental Lender”) to repay Indebtedness (including Revolving Credit Loans) incurred in connection with the purchase of approximately 93,000 subscriber accounts from Pinnacle Security (the “Acquisition”), to finance fees and expenses related to this Amendment and all related transactions, and for ongoing working capital and for other general corporate purposes of the Borrower and its Subsidiaries.  The Incremental Lender is willing to extend such incremental Term Loans, subject to the terms and conditions of this Amendment, in connection with the syndication of such incremental Term Loans to various Eligible Assignees.  This Amendment, the funding of such incremental Term Loans, the Acquisition and all related transactions are hereinafter collectively referred to as the “Transaction”.

C.                                    Borrower, the Administrative Agent and the undersigned Lenders wish to amend the Credit Agreement and grant certain consents on the terms and conditions set forth below.

Now, therefore, in consideration of the mutual execution hereof and other good and valuable consideration, the parties hereto agree as follows:

1.                                      Defined Terms.  Unless otherwise defined herein, capitalized terms used herein shall have the meanings, if any, assigned to such terms in the Credit Agreement.

2.                                      Interpretation.  The rules of interpretation set forth in Section 1.02 of the Credit Agreement shall be applicable to this Amendment and are incorporated herein by this reference.

3.                                      Amendments to Credit Agreement.  Upon the Effective Date (as defined below), the Credit Agreement shall be amended as follows:

(a)                                 The defined terms “Acquisition Pro Forma”, “Acquisition Projections” and “Target” in Section 1.01 of the Credit Agreement are hereby deleted.

(b)                                 Section 2.06(a) of the Credit Agreement is hereby deleted and replaced with the following:

(a)                                 Term Loans.  The Borrower shall repay to the Term Lenders on the last day of each quarter an amount equal to 0.25% of the initial aggregate principal amount of each Term Loan (which amounts shall be reduced as a result of the application of prepayments in accordance with the order of priority set forth in Section 2.04).  The final

principal repayment installment of the Term Loans shall be repaid on the Maturity Date for the Term Facility and in any event shall be in an amount equal to the aggregate principal amount of all Term Loans outstanding on such date.

(c)                                  Section 2.15 of the Credit Agreement is hereby deleted and replaced with the following:

(a)                                 Request for Increase.  Provided there exists no Default, upon notice to the Administrative Agent, the Borrower may from time to time, request an increase in the Revolving Credit Facility by an amount (for all such requests) not exceeding $150,000,000 (less the amount of an increase in the Term Facility pursuant to Section 2.16) plus an additional amount if, after giving pro forma effect to the incurrence of such additional amount, the Consolidated Senior Secured Leverage Ratio is equal to or less than 2.75:1.00 (and assuming all such additional amounts were secured, whether or not so secured and calculated as if any incremental Revolving Credit Facility being initially provided on any date of determination were fully drawn on such date); provided that (i) any such request for an increase shall be in a minimum amount of $10,000,000, (ii) the Borrower may make a maximum of five (less the amount of any requests to increase the Term Facility pursuant to Section 2.16) such requests, and (iii) all new Revolving Credit Commitments shall be on the same terms as the existing Revolving Credit Commitments except that such new Revolving Credit Commitments may have pricing that is greater than the pricing for the existing Revolving Credit Commitments (not taking into consideration customary arrangement, structuring, underwriting, commitment, upfront or similar fees payable in connection with such new Revolving Credit Commitments or in connection with any prior syndication of the Revolving Credit Commitments in effect on the Closing Date).  In the event that such pricing of the new Revolving Credit Commitments is greater than the existing Revolving Credit Commitments, then the pricing of the existing Revolving Credit Commitments shall be increased to the extent necessary so that such pricing is equal to the pricing of the new Revolving Credit Commitments.

(b)                                 Proposed Lenders.  Any proposed increase in the Revolving Credit Facility may be requested from existing Lenders, new prospective lenders who are Eligible Assignees (and who are approved by the Administrative Agent, which approval shall not be unreasonably withheld) or a combination thereof, as selected by, and with such allocations of committed amounts as may be determined by, the lead arranger(s) thereof and/or the Borrower.  Any Lender approached to provide all or a portion of the incremental Revolving Credit Facility may elect or decline, in its sole discretion, to provide an incremental Revolving Credit Facility.

(c)                                  Effective Date and Allocations.  If the Revolving Credit Facility is increased in accordance with this Section, the Administrative Agent shall promptly notify the Borrower and the Revolving Credit Lenders of the amount and effective date (the “Revolving Credit Increase Effective Date”) of such increase.

(d)                                 Conditions to Effectiveness of Increase.  As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent (1) a certificate of each Loan Party dated as of the Revolving Credit Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of such Loan Party (i) certifying

and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (ii) in the case of the Borrower, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article V and the other Loan Documents are true and correct in all material respects (or with respect to representations and warranties qualified by materiality, in all respects) on and as of the Revolving Credit Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct in all material respects (or with respect to representations and warranties qualified by materiality, in all respects) as of such earlier date, and except that for purposes of this Section 2.15, the representations and warranties contained in subsections (a) and (b) of Section 5.05 shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 6.01, and (B) no Default exists and (2) any consent of the Borrower reasonably requested by the Administrative Agent in connection with such increase under Section 2.15(f).  In furtherance of the foregoing, each of the parties hereto hereby agrees that the Administrative Agent shall reallocate the outstanding Revolving Credit Loans amongst the Lenders based on their respective Revolving Credit Commitments as may be reasonably necessary to ensure that all Revolving Credit Loans are held by the Lenders pro rata in accordance with their respective Revolving Credit Commitments.

(e)                                  Conflicting Provisions.  This Section shall supersede any provisions in Section 2.12 or 10.01 to the contrary.

(f)                                   Amendments.  Each of the parties hereto hereby agrees that, upon the effectiveness of any increase of the Revolving Credit Facility, this Agreement may be amended to the extent (but only to the extent) necessary to reflect the existence and terms of the new Revolving Credit Commitments evidenced thereby as provided for in the last paragraph of Section 10.01.  Any such amendment may be memorialized in writing by the Administrative Agent with the Borrower’s consent (not to be unreasonably withheld) and furnished to the other parties hereto.  Each new Lender shall deliver such incremental commitment agreements and other documentation as the Borrower and the Administrative Agent shall reasonably request.

(d)                                 Section 2.16 of the Credit Agreement is hereby deleted and replaced with the following:

(a)                                 Request for Increase.  Provided there exists no Default, upon notice to the Administrative Agent, the Borrower may from time to time, request an increase in the Term Facility by an amount (for all such requests after November 7, 2012) not exceeding $150,000,000 (less the amount of an increase in the Revolving Credit Facility pursuant to Section 2.15) plus an additional amount if, after giving pro forma effect to the incurrence of such additional amount, the Consolidated Senior Secured Leverage Ratio is equal to or less than 2.75:1.00 (and assuming all such additional amounts were secured, whether or not so secured and calculated as if any incremental Revolving Credit Facility being initially provided on any date of determination were fully drawn on such date); provided that (i) any such request for an increase shall be in a minimum amount of $10,000,000, (ii) the Borrower may make a maximum of five (less the amount of any requests to increase the Revolving Credit Facility pursuant to Section 2.15) such requests after November 7, 2012, and (iii) any new Term Loans may be part of the same or a different tranche of Term Loans and shall be on the same terms as the existing Term Loans except that such new Term Loans may have: (a) pricing that is greater than the pricing for the

existing Term Loans by not more than 0.50% per annum (with any determination thereof taking into consideration any increase in the Eurodollar Rate floor or original issue discount or upfront or similar fees, with each of the foregoing being equated to such pricing in a manner determined by the Administrative Agent and consistent with generally accepted financial practice based on an assumed four-year life to maturity, but not taking into consideration customary arrangement, structuring, underwriting, commitment or similar fees) unless the Borrower elects to increase the pricing for the existing Term Loans to the extent necessary so that the pricing for the new Term Loans is not more than 0.50% per annum higher than the pricing for the existing Term Loans, (b) pricing that is lower than the pricing for the existing Term Loans (with any determination thereof taking into consideration any decrease in the Eurodollar Rate floor or original issue discount or upfront or similar fees, with each of the foregoing being equated to such pricing in a manner determined by the Administrative Agent and consistent with generally accepted financial practice based on an assumed four-year life to maturity, but not taking into consideration customary arrangement, structuring, underwriting, commitment or similar fees), and (c) later maturities or less amortization than the existing Term Loans.

(b)                                 Proposed Lenders.  Any proposed increase in the Term Facility may be requested from existing Lenders, new prospective lenders who are Eligible Assignees (and who are approved by the Administrative Agent, which approval shall not be unreasonably withheld) or a combination thereof, as selected by, and with such allocations of committed amounts as may be determined by, the lead arranger(s) thereof and/or the Borrower.  Any Lender approached to provide all or a portion of the incremental Term Facility may elect or decline, in its sole discretion, to provide an incremental Term Facility.

(c)                                  Effective Date and Allocations.  If the Term Facility is increased in accordance with this Section, the Administrative Agent shall promptly notify the Borrower and the Term Lenders of the amount and effective date (the “Term Increase Effective Date”) of such increase.

(d)                                 Conditions to Effectiveness of Increase.  As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent (1) a certificate of each Loan Party dated as of the Term Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of such Loan Party (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (ii) in the case of the Borrower, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article V and the other Loan Documents are true and correct in all material respects (or with respect to representations and warranties qualified by materiality, in all respects) on and as of the Term Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct in all material respects (or with respect to representations and warranties qualified by materiality, in all respects) as of such earlier date, and except that for purposes of this Section 2.16, the representations and warranties contained in subsections (a) and (b) of Section 5.05 shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 6.01, and (B) no Default exists and (2) any consent of the Borrower reasonably requested by the Administrative Agent in connection with such increase under Section 2.16(f).  The additional Term Loans shall be made by

the Term Lenders participating therein pursuant to the procedures set forth in Section 2.02.

(e)                                  Conflicting Provisions.  This Section shall supersede any provisions in Section 2.12 or 10.01 to the contrary.

(f)                                   Amendments.  Each of the parties hereto hereby agrees that, upon the effectiveness of any increase of the Term Facility pursuant to this Section 2.16, this Agreement may be amended to the extent (but only to the extent) necessary to reflect the existence and terms of the new Term Loans evidenced thereby as provided for in the last paragraph of Section 10.01.  Any such deemed amendment may be memorialized in writing by the Administrative Agent with the Borrower’s consent (not to be unreasonably withheld) and furnished to the other parties hereto.  Each new Lender shall deliver such incremental commitment agreements and other documentation as the Borrower and the Administrative Agent shall reasonably request.
