1. DESCRIPTION OF EXISTING INDEBTEDNESS AND OBLIGATIONS. Among other indebtedness and obligations which may be owing by Borrower to Bank, Borrower is indebted to Bank pursuant to a loan arrangement dated as of October 18, 2012, evidenced by, among other documents, a certain Subordinated Loan and Security Agreement dated as of October 18, 2012, between Borrower and Bank (as amended, the “Loan Agreement”). Capitalized terms used but not otherwise defined herein shall have the same meaning as in the Loan Agreement.

2. DESCRIPTION OF COLLATERAL. Repayment of the Obligations is secured by the Collateral as described in the Loan Agreement and the “Intellectual Property Collateral”, as such term is defined in that certain Intellectual Property Security Agreement dated as of October 18, 2012 between Bank, Mavenir and Holdings and that certain Intellectual Property Security Agreement dated as of the November 16, 2012 between Bank and Mavenir IP (collectively and as amended, the “IP Security Agreement”, and together with any other collateral security granted by any Borrower or Guarantor to Bank, the “Security Documents”). Hereinafter, the Security Documents, together with all other documents evidencing or securing the Obligations shall be referred to as the “Existing Loan Documents”.

3. JOINDER AND ASSUMPTION. New Borrower is a Subsidiary of Mavenir and an affiliate of each other Borrower. New Borrower hereby joins the Loan Agreement and each of the other appropriate Existing Loan Documents, and agrees to comply with and be bound by all of the terms, conditions and covenants of the Loan Agreement and each of the other appropriate Existing Loan Documents, as if New Borrower were originally named a “Borrower” and/or a “Debtor” therein. Without limiting the generality of the preceding sentence, New Borrower hereby assumes and agrees to pay and perform when due all present and future indebtedness, liabilities and obligations of Borrower under the Loan Agreement, including, without limitation, the Obligations. From and after the date hereof, all references in the Existing Loan Documents to “Borrower” and/or “Debtor” shall be deemed to refer to and include New Borrower. Further, all references to the “Obligations” of Borrower shall be deemed to include all present and future Obligations of New Borrower. New Borrower acknowledges that the Obligations are due and owing to Bank from Borrower including, without limitation, New Borrower, without any defense, offset or counterclaim of any kind or nature whatsoever as of the date hereof.

4. GRANT OF SECURITY INTEREST. In addition to any liens, pledges or security interests in the Collateral granted pursuant to the other Security Documents, to secure the payment and performance of all of the Obligations, New Borrower hereby grants to Bank a continuing lien upon and security interest in all of New Borrower’s now existing or hereafter arising rights and interest in the Collateral, whether now owned or existing or hereafter created, acquired, or arising, and wherever located, including, without limitation, all of New Borrower’s

assets listed on Exhibit A attached to the Loan Agreement and all of New Borrower’s books and records relating to the foregoing and any and all claims, rights and interests in any of the above and all substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance proceeds of any or all of the foregoing. New Borrower represents, warrants, and covenants that, upon the filing of appropriate financing statements, continuation statements or other appropriate filings, the security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens that expressly or by operation of law have superior priority to Bank’s Lien in this Agreement). Notwithstanding the foregoing, Bank’s security interest in the assets of New Borrower securing the Obligations of New Borrower to Bank under the Loan Agreement shall be junior and subordinate to Bank’s security interest in the assets of New Borrower securing the Obligations of Borrower under the Senior Loan Agreement (as defined in the Loan Agreement). If New Borrower shall acquire a commercial tort claim, Borrower shall promptly notify Bank in a writing signed by Borrower of the general details thereof and grant to Bank in such writing a security interest therein and in the proceeds thereof, all upon the terms of the Loan Agreement, with such writing to be in form and substance reasonably satisfactory to Bank. New Borrower further covenants and agrees that following written notice from Bank, it shall provide all such information, complete all such forms, and take all such actions, and enter into all such agreements, in form and substance reasonably satisfactory to Bank that are reasonably deemed necessary by Bank in order to grant and continue a valid, first perfected security interest to Bank in the Collateral. New Borrower hereby authorizes Bank to file financing statements or any other applicable filings, without notice to Borrower, with all appropriate jurisdictions to perfect or protect Bank’s interest or rights hereunder, including a notice that any disposition of the Collateral, by either Borrower or any other Person, may be deemed to violate the rights of Bank under the Code. Such financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in Bank’s discretion. Bank shall terminate the security interest granted herein in accordance with Section 4.1 of the Loan Agreement.

5. SUBROGATION AND SIMILAR RIGHTS. Borrower (in each case including, without limitation, New Borrower) waives any suretyship defenses available to it under the Code or any other applicable law. Borrower waives any right to require Bank to: (i) proceed against any other Borrower or any other Person; (ii) proceed against or exhaust any security; or (iii) pursue any other remedy. Bank may exercise or not exercise any right or remedy it has against any Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale) without affecting any Borrower’s liability. Notwithstanding any other provision of this Agreement or other related document, so long as any Obligation remains outstanding, each Borrower irrevocably subordinates in priority and payment to the indefeasible repayment in full in cash of the Obligations all rights that it may have at law or in equity (including, without limitation, any law subrogating such Borrower to the rights of Bank under the Loan Agreement) to seek contribution, indemnification or any other form of reimbursement from any other Borrower or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, for any payment made by a Borrower with respect to the Obligations in connection with the Loan Agreement or otherwise and all rights that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by any Borrower with respect to the Obligations in connection with the Loan Agreement or otherwise. Any agreement providing for indemnification, reimbursement or any other arrangement prohibited under this section shall be null and void. If any payment is made to any Borrower in contravention of this section, such Borrower shall hold such payment in trust for Bank and such payment shall be promptly delivered to Bank for application to the Obligations, whether matured or unmatured. Any Borrower may, acting singly, request Credit Extensions under the Loan Agreement. Each Borrower hereby appoints the other as agent for the other for all purposes under the Loan Agreement, including with respect to requesting Credit Extensions thereunder. Each Borrower shall be jointly and severally obligated to repay all Credit Extensions made under the Loan Agreement or any other Loan Documents, regardless of which Borrower actually received said Credit Extension, as if each Borrower directly received all Credit Extensions.

6. REPRESENTATIONS AND WARRANTIES. Borrower hereby represents and warrants to Bank that all representations and warranties in the Loan Documents made on the part of any Borrower are true and correct on the date hereof with respect to New Borrower (provided that those representations and warranties expressly referring to a specific date shall be true, accurate and complete in all material respects as of such date), with the same force and effect as if New Borrower were originally named as “Borrower” in the Loan Documents. In addition, Borrower and New Borrower hereby represent and warrant to Bank that this Agreement has been duly executed and delivered by Borrower and New Borrower, and constitutes their legal, valid and binding obligation, enforceable against each in accordance with its terms. Hereafter, each reference to “Borrower” and/or “Debtor”) in any Loan Document shall be deemed to reference both Borrower and New Borrower.
