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 Senior 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). 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.

Bank receives a net sum equal to the sum which it would have received had no withholding or deduction been required and Borrower shall pay the full amount withheld or deducted to the relevant governmental authority. Borrower will, upon request,
furnish Bank with proof satisfactory to Bank indicating that Borrower has made such withholding payment provided, however, that Borrower need not make any withholding payment if the amount or validity of such withholding payment is contested in good

restrictions set forth in this Section 6.3(c)(ii) shall not apply to the proceeds of any Accounts after such proceeds have been transferred out of the U.K. Blocked Account in accordance with this Section 6.3(c)(ii) or to any funds

registered under the laws of England and Wales under company number 04388973 whose registered office is at 76 Wallingford Road, Shillingford, Oxfordshire OX10 7EU, United Kingdom (“Mavenir U.K.” and together with U.K. Holdings, the
“U.K. Borrower”), and (v) MAVENIR SYSTEMS PTE LTD., a company incorporated under the laws of Singapore with registration number 200105057D and having its registered office located at 18 Mohamed Sultan Road, #03-01,
Singapore 238967 (“Mavenir Singapore” or “Singapore Borrower”, and together with U.K. Holdings and Mavenir U.K., individually and collectively, jointly and severally, the “New Borrower”).

 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.

Specifically, however, if at any time any governmental authority, applicable law, regulation or international agreement requires Borrower to make any such withholding or deduction from any such payment or other sum payable hereunder to Bank,
Borrower hereby covenants and agrees that the amount due from Borrower with respect to such payment or other sum payable hereunder will be increased to the extent necessary to ensure that, after the making of such required withholding or deduction,
Bank receives a net sum equal to the sum which it would have received had no withholding or deduction been required and Borrower shall pay the full amount withheld or deducted to the relevant governmental authority. Borrower will, upon request,
furnish Bank with proof satisfactory to Bank indicating that Borrower has made such withholding payment provided, however, that Borrower need not make any withholding payment if the amount or validity of such withholding payment is contested in good
faith by appropriate and timely proceedings and as to which payment in full is bonded or reserved against by Borrower. The agreements and obligations of Borrower contained in this Section 2.5 shall survive the termination of this

future enter, into Bank Services Agreements with Bank. Regardless of the terms of any Bank Services Agreement, Borrower agrees that any amounts Borrower owes Bank thereunder shall be deemed to be Obligations hereunder and that it is the intent of
