AMENDMENT NO. 2 TO CREDIT AGREEMENT,
dated as of February 11, 2011 (this Amendment), among AVAYA INC., a Delaware corporation (the Borrower), CITIBANK, N.A., as Administrative Agent (in such capacity, the Administrative
Agent) and the Lenders (as defined below) party hereto.

PRELIMINARY STATEMENTS

A. The Borrower, Sierra Holdings Corp., a Delaware corporation (Holdings), the Administrative Agent and each lender
from time to time party thereto (the Lenders) have entered into a Credit Agreement, dated as of October 26, 2007, as amended by Amendment No. 1 dated as of December 18, 2009 (as amended, supplemented or otherwise
modified from time to time through the date hereof, the Original Credit Agreement).

B. The parties hereto
wish to amend and restate the Original Credit Agreement in its entirety on the terms set forth in the Restated Credit Agreement (as defined below) to, among other things (a) extend the maturity of a portion of the Term B-1 Loans, and
(b) permit future refinancings and extensions of the Term Loans and Revolving Credit Commitments.

C. Each Term B-1
Lender who executes and delivers this Amendment as an Electing Term Lender has agreed to extend the maturity of all or a portion of such Term B-1 Lenders Term B-1 Loans in accordance with the terms and subject to the conditions set
forth herein.

D. Each Lender who executes and delivers this Amendment has agreed to amend the Original Credit Agreement to be
in the form of Annex A hereto.

NOW, THEREFORE, in consideration of the premises and for other good and valuable
consideration, the sufficiency and receipt of all of which is hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. Definitions. Capitalized terms not otherwise defined in this Amendment have the same meanings as specified in the
Restated Credit Agreement or, if not defined therein, in the Original Credit Agreement.

SECTION 2. Amendment and
Restatement. Effective as of the Restatement Effective Date (as defined below), and subject to the terms and conditions set forth herein, (i) the Original Credit Agreement is hereby amended and restated in the form of Annex A hereto
(the Original Credit Agreement, as so amended and restated, being referred to as the Restated Credit Agreement), (ii) the Schedules attached hereto replace in their entirety the corresponding Schedules attached to the
Original Credit Agreement and (ii) the Exhibits attached hereto hereby replace in their entirety the corresponding Exhibits attached to the Original Credit Agreement, if any, or constitute new Exhibits to the Restated Credit Agreement, as
applicable.

SECTION 3. Extension of Certain of the Term B-1 Loans.

(a) Each Lender that is a Term B-1 Lender on the date hereof (an Existing Term B-1 Lender) may elect (an
Electing Term Lender) to become a Term B-3 Lender and holder of a Term B-3 Loan subject to all of the rights, obligations and conditions thereto under the Restated Credit Agreement by executing the appropriate signature page in
accordance with Section 3(b) hereof and delivering to the Administrative Agent such signature page (the Term B-3 Loan Extension Election) stating the amount of such Lenders Term B-1 Loans outstanding immediately prior
to the effectiveness



---

of the Restated Credit Agreement (Existing Term B-1 Loans) that such Lender would like to extend and reclassify as Term B-3 Loans upon the effectiveness of the Restated Credit
Agreement (the Proposed Term B-3 Loan Amount); provided that the aggregate amount of all Existing Term B-1 Loans that may be reclassified as Term B-3 Loans in accordance with this Section 3(b) shall not exceed sixty
percent (60%) of the aggregate principal amount of Existing Term B-1 Loans outstanding immediately prior to the effectiveness of the Restated Credit Agreement (such amount, the Extended Term Loan Cap). In the event that the
Electing Term Lenders collectively submit Term B-3 Loan Extension Elections prior to the Consent Deadline (as defined below) to extend and reclassify an aggregate principal amount of Existing Term B-1 Loans in excess of the Extended Term Loan Cap,
each Electing Term Lender shall be deemed to have elected to extend and reclassify as Term B-3 Loans a principal amount of its Term B-1 Loans equal to the product of its Proposed Term B-3 Loan Amount multiplied by the quotient obtained by dividing
the Extended Term Loan Cap by the aggregate Proposed Term B-3 Loan Amount of all Lenders obtained prior to the Consent Deadline, with rounding adjustments with respect to the amount to be allocated to each such Electing Term Lender as the
Administrative Agent may determine in its discretion (any such reduction in any Lenders Proposed Term B-3 Loan Amount as described in this sentence, an Extension Cutback).

(b) On the Restatement Effective Date, if the aggregate Proposed Term B-3 Loan Amount of all Electing Term Lenders obtained prior to the
Consent Deadline is less than or equal to the Extended Term Loan Cap (including as a result of any Extension Cutbacks), each Existing Term B-1 Lender that has executed and delivered a counterpart to this Amendment as an Electing Term
Lender (each, a Term B-3 Lender) and has designated on its signature page an aggregate principal amount of its Existing Term B-1 Loans to be treated as an Extended Amount (a Term B-3 Loan)
shall have its Existing Term B-1 Loan automatically reclassified as a Term B-3 Loan for the purpose of the Restated Credit Agreement, in an aggregate principal amount equal to its Proposed Term B-3 Loan Amount, as adjusted by any Extension Cutback
(such amount, as adjusted, the Term B-3 Loan Amount).

SECTION 4. Conditions of Effectiveness. This
Amendment and the amendment and restatement of the Original Credit Agreement as set forth in Section 2 hereof shall become effective as of the first date (such date being referred to as the Restatement Effective Date) when
each of the following conditions shall have been satisfied:

have received (i) this Amendment, duly executed and delivered by (A) the Borrower, (B) each Electing Term Lender, (C) the Required Lenders, and (D) the Required Facility Lenders for the Term B-1 Loans as defined in the
Original Credit Agreement and (ii) a Guarantor Consent and Reaffirmation, in the form of Annex B hereto, duly executed and delivered by each Guarantor.

(b) Consent Fee. The Administrative Agent shall have received from the Borrower a consent fee payable in Dollars for the account of each Lender (other than a Defaulting Lender) that has returned an
executed signature page to this Amendment to the Administrative Agent at or prior to 5:00 p.m., New York City time on February 1, 2011 (the Consent Deadline and each such Lender, a Consenting Lender) equal
to 0.25% of the sum of (x) the aggregate principal amount of Term Loans, if any, held by such Consenting Lender as of the Consent Deadline with respect to which a consent was delivered and (y) the aggregate amount of the Revolving Credit
Commitment, if any, of such Consenting Lender as of the Consent Deadline with respect to which a consent was delivered.

(c)
Certificate of Responsible Officer. The Administrative Agent shall have received a certificate of a Responsible Officer of the Borrower, certifying the conditions precedent set forth in Sections 4.02(a) and (b) of the Restated Credit
