 THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE

MAVENIR SYSTEMS, INC. 
 STOCK PURCHASE WARRANT 
 THIS
CERTIFIES that Communities Foundation of Texas (the “Holder”) is entitled, upon the terms and subject to the conditions hereinafter set forth, at any time on or after the date of this Warrant and on or prior to the fifth anniversary
hereof (the “Expiration Date”), to subscribe for and purchase, from Mavenir Systems, Inc., a Delaware corporation (the “Company”), 20,000 shares of Common Stock, $0.001 par value per share, (or other securities as
to which purchase rights under this Warrant exist) (the “Shares”) at an exercise price of $0.73 per share (the “Exercise Price”). The Exercise Price and the Shares purchasable hereunder are subject to adjustment as
set forth in Section 8. 
 1. Exercise of Warrant. 

(a) The purchase rights represented by this Warrant are exercisable by the Holder, in whole or in part, at any time after the
date hereof and before the close of business on the Expiration Date, by the surrender of this Warrant and the Notice of Exercise annexed hereto duly executed at the principal executive office of the Company (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Company), and upon payment of the Exercise Price of the Shares thereby purchased (by cash or by check or bank draft payable to
the order of the Company); whereupon the Holder shall be entitled to receive a certificate for the number of Shares so purchased. The Company agrees that if at the time of the surrender of this Warrant and purchase of the Shares, the Holder shall be
entitled to exercise this Warrant, the Shares so purchased shall be and be deemed to be issued to the Holder as the record owner of such Shares as of the close of business on the date on which this Warrant shall have been exercised as aforesaid.

 (b) In lieu of exercising this Warrant by payment of cash or check pursuant to subsection (a) above, the Holder may
elect to receive Shares equal to the value of this Warrant (or the portion thereof being exercised), at any time after the date hereof and before the close of business on the Expiration Date, by surrender of this Warrant at the principal executive
office of the Company, together with the Notice of Conversion annexed hereto, in which event the Company will issue to the Holder Shares in accordance with the following formula: 








							
		 	X	  	=	  	Y(A-B)
		 		  		  	    A
	 	  	  	

  

											
		 		 	Where,	  	X	  	=	  	the number of Shares to be issued to Holder;
						
		 		 		  	Y	  	=	  	the number of Shares for which the Warrant is being exercised;
						
		 		 		  	A	  	=	  	the fair market value of one Share; and
						
		 		 		  	B	  	=	  	the Exercise Price.

 (i) For purposes of this subsection (b), the fair market value of a Share is defined as follows:

 (1) if the exercise is in connection with an initial public offering of the Common Stock, and if the Company’s
registration statement relating to such offering has been declared effective by the Securities and Exchange Commission, then the fair market value shall be the initial “Price to Public” specified in the final prospectus with respect to the
offering; 
 (2) if the exercise is in connection with a Change of Control (as defined below), then the fair market value shall
be the value received in such Change of Control by the holders of the securities as to which purchase rights under this Warrant exist; 
 (3) if the exercise occurs after, and not in connection with the Company’s initial public offering, and: 
 a) if traded on a securities exchange or the Nasdaq Stock Market, the value shall be deemed to be the average of the closing prices of the securities on such exchange or market over the thirty
(30) day period ending three (3) days prior to the date of the Notice of Conversion; or 
 b) if actively traded
over-the-counter, the value shall be deemed to be the average of the closing bid prices over the thirty (30) day period ending three (3) days prior to the date of the Notice of Conversion; 

(4) if there is no active public market, the value shall be the fair market value thereof, as determined in good faith by the
Company’s Board of Directors. 
 (ii) A “Change of Control” shall mean (x) the acquisition of the
Company by another entity by means of any transaction or series of related transactions (including, without limitation, any merger, consolidation or other form of reorganization in which outstanding shares of the Company are exchanged for securities
or other consideration issued, or caused to be issued, by the acquiring entity or its subsidiary, but excluding any transaction effected primarily for the purpose of changing the Company’s jurisdiction of incorporation), unless the
Company’s stockholders of record as constituted immediately prior to such transaction or series of related transactions will, immediately after such transaction or series of related transactions hold at least a majority of the voting power of
the surviving or acquiring entity or (y) a sale of all or substantially all of the assets of the Company.

 2. Nonassessable. The Company covenants that all Shares which may be issued upon the
exercise of rights represented by this Warrant will, upon exercise of the rights represented by this Warrant, be validly issued, fully paid and nonassessable and free from all taxes, liens and charges in respect of the issue thereof (other than
taxes in respect of any transfer occurring contemporaneously with such issue). Certificates for Shares purchased hereunder shall be delivered to the Holder within a reasonable time after the date on which this Warrant shall have been exercised as
aforesaid. 
 3. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of this Warrant. With respect to any fraction of a share called for upon the exercise of this Warrant, an amount equal to such fraction multiplied by the then current price at which each Share may be purchased hereunder
shall be paid in cash to the Holder. 
 4. Charges, Taxes and Expenses. Issuance of certificates for Shares upon the
exercise of this Warrant shall be made without charge to the Holder hereof for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and
such certificates shall be issued in the name of the Holder. 
 5. No Rights as Stockholder. This Warrant does not
entitle the Holder to any voting rights or other rights as a stockholder of the Company prior to the exercise hereof. 
 6.
Loss, Theft, Destruction or Mutilation of Warrant. On receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity
agreement satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and
amount. 
 7. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the
expiration of any right required or granted herein shall be a Saturday, a Sunday or a legal holiday, then such action may be taken or such right may be exercised on the next succeeding day not a Saturday, Sunday or legal holiday. 

8. Adjustments. The Exercise Price and the number of Shares purchasable hereunder are subject to adjustment from time to time as
set forth in this Section 8. 
 (a) Reclassification, etc. If the Company, at any time while this Warrant, or any
portion hereof, remains outstanding and unexpired by reclassification of securities or otherwise, shall change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities or any other
class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights under
this Warrant immediately prior to such reclassification or other change and the Exercise Price therefor shall be appropriately adjusted, all subject to further adjustment as provided in this Section 8.

 (b) Subdivision or Combination of Shares. In the event that the Company shall at any
time subdivide the outstanding securities as to which purchase rights under this Warrant exist, or shall issue a stock dividend on the securities as to which purchase rights under this Warrant exist, the number of securities as to which purchase
rights under this Warrant exist immediately prior to such subdivision or to the issuance of such stock dividend shall be proportionately increased, and the Exercise Price shall be proportionately decreased, and in the event that the Company shall at
any time combine the outstanding securities as to which purchase rights under this Warrant exist, the number of securities as to which purchase rights under this Warrant exist immediately prior to such combination shall be proportionately decreased,
and the Exercise Price shall be proportionately increased, effective at the close of business on the date of such subdivision, stock dividend or combination, as the case may be. 

(c) Cash Distributions. No adjustment on account of cash dividends or interest on the securities as to which purchase rights under
this Warrant exist will be made to the Exercise Price under this Warrant. 
 9. Restrictions on Transferability of
Securities. 
 (a) Restrictions on Transferability. This Warrant and the Shares issuable upon exercise of this Warrant
(collectively the “Securities”) shall not be sold, assigned, transferred or pledged except upon the conditions specified in this Section 9. 
 (b) Restrictive Legend. Each certificate representing the Securities and any other securities issued in respect of the Securities upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall (unless otherwise permitted by the provisions of Section 9(c)) be stamped or otherwise imprinted with a legend in the following form (in addition to any legend required under applicable state securities
laws): 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
OR QUALIFIED UNDER APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT AND QUALIFIED UNDER APPLICABLE STATE SECURITIES LAWS, OR UNLESS THE CORPORATION HAS
RECEIVED AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION OR QUALIFICATION IS NOT REQUIRED. 
 Each holder of Securities and each subsequent transferee consents to the Company making a notation on its records and giving instructions to any transfer agent of the Securities in order to implement the
restrictions on transfer established in this Section 9.

 (c) Notice of Proposed Transfers. Each holder of a warrant or stock certificate, as
the case may be, representing the Securities, by acceptance thereof, agrees to comply in all respects with the provisions of this Section 9(c). Such holder agrees not to make any disposition of all or any portion of the Securities unless and
until (X) there is then in effect a registration statement under the Securities Act of 1933, as amended (the “Securities Act”) covering such proposed disposition and such disposition is made in accordance with such registration
statement or (Y) such holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by
the Company, such holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company that such disposition will not require registration of such shares under the Securities Act. 

10. Investment Representations and Covenants of the Holder. With respect to the acquisition of any of the Securities, the Holder
hereby represents and warrants to the Company as follows: 
 (a) Experience. The Holder is capable of evaluating the
merits and risks of its investment in the Company and has the capacity to protect its own interests. 
 (b) Investment.
The Holder is acquiring the Securities for investment for its own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof. The Holder understands that the Securities have not been, and
will not be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act, the availability of which depends upon, among other things, the bona fide nature of the investment intent and
the accuracy of the Holder’s representations as expressed herein. 
 (c) Rule 144. The Holder acknowledges that
the Securities must be held indefinitely unless subsequently registered under the Securities Act, or unless an exemption from such registration is available. The Holder understands that the Company is not under any obligation to register any of the
Securities. The Holder is aware of the provisions of Rule 144 promulgated under the Securities Act that permit limited resale of securities purchased in a private placement subject to satisfaction of certain conditions. 

(d) Market Standoff. The Holder hereby agrees that it will not, without the prior written consent of the managing underwriter,
during the period commencing on the date of the final prospectus relating to the Company’s initial public offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (l80)
calendar days) (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or
indirectly, any securities of the Company, including (without limitation) shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (whether now owned or hereafter acquired) or (ii) enter into any
swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any securities of the Company, including (without limitation) shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock (whether now owned or hereafter acquired), whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of securities, in cash or otherwise. The Holder
agrees to execute an agreement(s) reflecting (i) and (ii) above as may be requested by the managing 

  
 - 5 -









 
underwriters at the time of the initial public offering, and further agrees that the Company may impose stop transfer instructions with its transfer agent in order to enforce the covenants in
(i) and (ii) above. The underwriters in connection with the Company’s initial public offering are intended third party beneficiaries of the covenants in this subsection and shall have the right, power and authority to enforce
such covenants as though they were a party hereto. 
 11. Early Termination. The purchase rights represented by this
Warrant shall terminate and be of no further force and effect upon the first to occur of (a) the closing of the Company’s first firm commitment underwritten public offering of its Common Stock or other securities pursuant to an effective
registration statement under the Securities Act or (b) the closing of a Change of Control. The Company shall will mail or cause to be mailed to the Holder a notice specifying the date on which either of the events specified in (a) or
(b) of this Section 11 is to take place at least five (5) days prior to the date therein specified. 
 12.
Notices. In the event (i) the Company shall take a record of the holders of the securities at the time receivable upon the exercise of this Warrant for the purpose of entitling them to receive any dividend or other distribution, or any
right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right, (ii) of any capital reorganization of the Company, (iii) of any reclassification of the capital stock of the
Company, (iv) of any Change of Control or (v) of any voluntary dissolution, liquidation or winding-up of the Company, then, and in each such case, the Company will mail or cause to be mailed to the Holder a notice specifying, as the case
may be, (A) the date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (B) the date on which such reorganization,
reclassification, Change of Control, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of the securities at the time receivable upon the exercise of this Warrant shall be entitled
to exchange such securities for the securities or other property deliverable upon such reorganization, reclassification, Change of Control, dissolution, liquidation or winding-up. Such notice shall be mailed at least five (5) days prior to the
date therein specified. 
 13. Miscellaneous. 
 (a) Governing Law. THIS AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS BY THE LAWS OF THE STATE OF DELAWARE AS SUCH LAWS ARE APPLIED TO AGREEMENTS BETWEEN DELAWARE RESIDENTS ENTERED INTO AND TO BE
PERFORMED ENTIRELY WITHIN DELAWARE, WITHOUT REGARD TO CONFLICT OF LAWS RULES. 
 (b) Restrictions. By acceptance hereof,
the Holder acknowledges that the Shares acquired upon the exercise of this Warrant may have restrictions upon its resale imposed by state and federal securities laws. 
 (c) Waivers and Amendments. This Warrant and any provisions hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of
the same is sought.

the prior written approval of the Company. This Warrant shall be binding upon any successors or assigns of the Company.

Holder agrees that such notice may given by facsimile or by electronic mail.
