period or subsequent to such reference period and on or prior to or in connection with the Calculation Date (each, for purposes of this definition, a “pro forma event”) shall be calculated on a pro forma basis assuming that all such
Investments, acquisitions, dispositions, mergers, consolidations, discontinued operations and operational changes (and the change of any associated fixed charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day
of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted Subsidiary of such Person or was merged with or into such Person or any Restricted Subsidiary thereof since the beginning of
such period shall have made or effected any Investment, acquisition, disposition, merger, consolidation or discontinued operation, in each case with respect to an operating unit of a business, or operational change that would have required
adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, merger, consolidation discontinued operation or
operational change had occurred at the beginning of the applicable four-quarter period. 
 For purposes of this definition, whenever pro
forma effect is to be given to any pro forma event, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of Syniverse. If any Indebtedness bears a floating rate of interest and is being given pro
forma effect, the interest on such Indebtedness shall be 

  
 16 

 
calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness if such
Hedging Obligation has a remaining term in excess of 12 months). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of Syniverse to be the
rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility or a Qualified Receivables Financing
computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or
similar rate, a Eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as Syniverse may designate. Any such pro forma calculation
may include, without limitation, (1) adjustments calculated in accordance with Regulation S-X under the Securities Act, (2) adjustments calculated to give effect to any Pro forma Cost Savings and (3) all adjustments of the type used
in connection with the calculation of “Adjusted EBITDA” as set forth in notes 11 and 12 under the caption “Summary—Summary Historical Consolidated Financial Data” in the Offering Memorandum to the extent such adjustments,

such matters as so established in such Notes Supplemental Indenture. 
 Such matters may also be established in a Notes Supplemental

Notes, in each case of clauses (i) through (iii) above, upon written order of the Issuer signed by an Officer of the Issuer (an “Authentication Order”), which Authentication Order shall, in the case of any issuance of Additional
Notes, certify that such issuance is in compliance with Section 3.3. In addition, each such Authentication Order shall specify the amount of Notes to be authenticated, the date on which the Notes are to be authenticated, whether the Notes are

terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same
rights as an Agent to deal with the Issuer or any Affiliate of the Issuer.

(iii) Within a reasonable period after expiration or termination of the Restricted Period, beneficial interests in each Temporary Regulation S
Global Note shall be exchanged for beneficial interests in a Permanent Regulation S Global Note upon delivery to the Depositary of the certification of compliance and the transfer of applicable Notes pursuant to the Applicable Procedures.
Simultaneously with the authentication of the corresponding Permanent Regulation S Global Note, the Trustee shall cancel the corresponding Temporary Regulation S Global Note. The aggregate principal amount of a Temporary Regulation S Global Note and
a Permanent Regulation S Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter
provided. 
 (iv) Notwithstanding anything to the contrary in this Section 2.6, a beneficial interest in the Temporary Regulation S
Global Note may not be exchanged for a Definitive Note or transferred to a Person who takes delivery thereof in the form of a Definitive Note prior to (X) the expiration of the Restricted Period and (Y) the receipt by the Registrar of any
certificates required pursuant to Rule 903(b)(3)(ii)(B) of the Securities Act, except in the case of a transfer pursuant to an exemption from the registration requirements of the Securities Act other than Rule 903 or Rule 904.

(i) Except as permitted by subparagraph (ii) below, each Global Note (other than an Unrestricted Global Note) and each Definitive Note
(and all Notes issued in exchange therefor or substitution thereof) shall bear the Private Placement Legend. 
 (ii) Notwithstanding the
foregoing, any Global Note or Definitive Note issued pursuant to subparagraph (b)(iv), (c)(iii), (c)(iv), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) of this Section 2.6 (and all Notes issued in exchange therefor or substitution thereof)
shall not bear the Private Placement Legend.

 (i) Global Note Legend. Each Global Note shall bear the Global Note Legend. 

(j) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged
for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the
principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the
beneficial interest is being exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made
on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
 (k) General Provisions
Relating to Transfers and Exchanges. 
 (i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee
shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.2 or at the Registrar’s request. 

(ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any
registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge
payable upon exchange or transfer pursuant to Sections 2.10, 3.7, 3.9, 3.18, 5.8, 5.9 and 9.4). 
 (iii) [Reserved]. 

(iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be
the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits hereof, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 

  
 70 

 (v) Neither the Registrar nor the Issuer shall be required (A) to issue, to register the
transfer of or to exchange any Notes during a period beginning at the opening of business on a Business Day 15 days before the sending of a notice of redemption of Notes and ending at the close of business on the day of such sending, (B) to
register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a Regular Record
Date and the next succeeding Interest Payment Date. 
 (vi) Prior to due presentment for the registration of a transfer of any Note, the
Trustee, any Agent, the Issuer and any Guarantor may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other
purposes, and none of the Trustee, any Agent, the Issuer or any Guarantor shall be affected by notice to the contrary. 
 (vii) The Trustee
shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.2. 
 (viii) All certifications,
certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.6 to effect a registration of transfer or exchange may be submitted by facsimile or electronically. 

(ix) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed
under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants or Indirect Participants) other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

(x) Neither the Trustee, the Issuer nor any Guarantor or Agent shall have any responsibility for any actions taken or not taken by the
Depositary. 
 SECTION 2.7 Replacement Notes. If any mutilated Note is surrendered to the Trustee, or the Issuer and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any Note prior to such Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (“protected purchaser”), the Issuer
shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Issuer’s and the Trustee’s requirements for replacements of Notes are met. The Holder must supply indemnity or security
sufficient in the judgment of the Trustee (with respect to the Trustee) and the Issuer (with respect to the Issuer) to protect the Issuer, the Trustee, any Agent or any 

  
 71 

 
authenticating agent from any loss which any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge for their fees and expenses in replacing a Note including amounts to
cover any tax, assessment, fee or other governmental charge that may be imposed in relation thereto. 
 Every replacement Note is an
obligation of the Issuer. 
 In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable,
the Issuer in its discretion may, instead of issuing a new Note, pay such Note. 
 SECTION 2.8 Outstanding Notes. The Notes outstanding at
any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.8 as not outstanding. 

If a Note is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Issuer and the Trustee receives proof satisfactory
to it that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under
Section 3.1 hereof, it shall cease to be outstanding and interest on it shall cease to accrue. 
 Subject to Section 2.9, a Note
does not cease to be outstanding because the Issuer, a Subsidiary of the Issuer or an Affiliate of the Issuer holds the Note. 
 SECTION 2.9
Treasury Notes. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent (other than in respect of any such action pursuant to Section 9.2(a), which requires the consent of
each Holder of an affected Note), Notes owned by the Issuer, any Subsidiary of the Issuer or any Affiliate of the Issuer shall be considered as though not outstanding, except that for purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Notes which a Trust Officer actually knows to be owned by the Issuer, any Subsidiary of the Issuer, or any Affiliate of the Issuer shall be considered as not outstanding. Upon request of the
Trustee, the Issuer shall promptly furnish to the Trustee an Officer’s Certificate listing and identifying all Notes, if any, known by the Issuer to be owned by any of the above-described Persons, and the Trustee shall be entitled to accept
such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. Notes owned by the Issuer, any Subsidiary of the
Issuer or any Affiliate of the Issuer that have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the reasonable satisfaction of the Trustee the pledgee’s right to act with respect to such Notes and that
the pledgee is not the Issuer, any Subsidiary of the Issuer or any Affiliate of the Issuer. 

  
 72 

 SECTION 2.10 Temporary Notes. Until definitive Notes are ready for delivery, the Issuer may
prepare and the Trustee shall upon receipt of an Authentication Order authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary
Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate definitive Notes in exchange for temporary Notes upon surrender of the temporary Notes for such exchange. Until
such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as definitive Notes. 
 SECTION 2.11
Cancellation. The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall
cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of all canceled Notes in its customary manner (subject to the record retention requirements of the Exchange Act), and upon
the written request of the Issuer, the Trustee shall deliver copies of such canceled Notes to the Issuer. The Issuer may not issue new Notes to replace Notes that it has redeemed or paid or that have been delivered to the Trustee for cancellation,
except as expressly permitted by this Indenture. 
 SECTION 2.12 Payment of Interest; Defaulted Interest. Interest on any Note which is
payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such
interest specified in the applicable Notes Supplemental Indenture. 
 Unless otherwise specified for Notes of any series in the applicable
Notes Supplemental Indenture, as contemplated by Section 2.1, any interest on any Note that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (“Defaulted Interest”) shall forthwith cease to be
payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Issuer, at its election, as provided in clause (a) or clause (b) below: 

(a) The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective
Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuer shall notify the Trustee and the Paying Agent in writing of the
amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (the “Special Interest Payment Date”), and at the same time the Issuer shall deposit with the Trustee or the Paying Agent an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or 

  
 73 

 
shall make arrangements reasonably satisfactory to the Trustee or the Paying Agent for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for
the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Issuer shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest, which shall be not more than 15
days and not less than 10 days prior to the Special Interest Payment Date and not less than 10 days after the receipt by the Trustee and the Paying Agent of the notice of the proposed payment. The Issuer shall promptly notify the Trustee of such
Special Record Date and shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 12.1, not less than 10 days
prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest
Payment Date to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b). 

(b) The Issuer may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange. 
 Subject to the
foregoing provisions of this Section 2.12, each Note delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Note of the same series shall carry the rights to interest accrued and unpaid, and to accrue, which
were carried by such other Note of such series. 
 SECTION 2.13 CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP”
numbers, ISINs and “Common Code” numbers (if then generally in use). The Trustee shall not be responsible for the use of “CUSIP” numbers, ISINs and “Common Code” numbers, and the Trustee makes no representation as to
their correctness as printed on any Note or notice to Holders, and any redemption shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Trustee in writing of any change in the “CUSIP”
numbers, ISINs and “Common Code” numbers, but failure to so notify the Trustee shall not constitute a Default or Event of Default by the Issuer. 

SECTION 2.14 [Reserved]. 

SECTION 2.15 Payment of Additional Interest. (a) Under certain circumstances, the Issuer may be obligated to pay Additional Interest to
the Holders of certain Initial Notes, as more particularly set forth in the Registration Rights Agreement entered into in connection with issuance of such Initial Notes. 

  
 74 

 (b) Under certain circumstances, the Issuer may be obligated to pay Additional Interest to the
Holders of certain Initial Additional Notes, as may be more particularly set forth in the Registration Rights Agreement, if any, entered into in connection with issuance of such Initial Additional Notes. 

(c) Prior to any Interest Payment Date on which any such Additional Interest is payable, the Issuer shall give notice to the Trustee of the
amount of any Additional Interest due on such Interest Payment Date. The Trustee shall have no duty to calculate or verify the calculation of any Additional Interest that is payable as determined by the Issuer.

all principal, premium, if any, and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture.

investors, market makers affiliated with any securities analysts (to the extent providing analysis of investment in the Notes) such information by (x) posting to its website or on IntraLinks or any comparable password-protected online data
system, which will require a confidentiality acknowledgment (but not restrict the recipients of such information in trading of securities of the Issuer or its affiliates) or (y) otherwise providing substantially comparable availability of such
reports (as determined by Syniverse in good faith) (it being understood that, without limitation, making such reports available on Bloomberg or another private electronic information service shall constitute substantially comparable availability) or

of the Notes, upon their request.

financial information, of the financial condition and results of operations of Syniverse or the Issuer, as applicable, and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Entities. 

  
 76 

 (d) For the avoidance of doubt, other than with respect to the reports required under clause
(a)(iii) above, the obligations of Syniverse under this Section 3.2 shall commence with respect to the first quarter that ends after the Issue Date. With respect to the reports required under clause (a)(iii) above, the obligations of Syniverse
under this covenant shall commence on the Issue Date. 
 (e) In addition, to the extent not satisfied by the foregoing, Syniverse shall agree
that, for so long as any Notes are outstanding, it shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act

via the EDGAR (or successor) filing system; provided that, if the information so furnished relates to such direct or indirect parent of Syniverse, the same is accompanied by consolidating information that explains in reasonable detail the

Section 3.2(h)(ii). 
 Delivery of such reports, information and documents to the Trustee is for informational purposes only and the

refinances, replaces, redeems, repurchases, retires or defeases (i) Subordinated Indebtedness, such Refinancing Indebtedness is Subordinated Indebtedness or (ii) Disqualified Stock or Preferred Stock, such Refinancing Indebtedness must be
Disqualified Stock or Preferred Stock, respectively; 
 (4) is Incurred in an aggregate principal amount (or if issued with
original issue discount an aggregate issue price) that is equal to or less than the sum of (x) the aggregate principal amount then outstanding of the Indebtedness being refunded, refinanced, replaced, redeemed, repurchased, retired or defeased
plus (y) the amount of premium, defeasance costs, unpaid interest and fees and expenses Incurred or payable in connection with such refunding, refinancing, replacement, redemption, repurchase, retirement or defeasance; and 

  
 81 

 (5) shall not include (x) Indebtedness, Disqualified Stock or Preferred
Stock of a Restricted Subsidiary of the Issuer that is not a Guarantor that refunds, refinances, replaces, redeems, repurchases, retires or defeases Indebtedness, Disqualified Stock or Preferred Stock of the Issuer or a Guarantor or
(y) Indebtedness or Disqualified Stock of the Issuer or Indebtedness, Disqualified Stock or Preferred Stock of a Restricted Subsidiary of the Issuer that refunds, refinances, replaces, redeems, repurchases, retires or defeases Indebtedness,

Acquisition Subsidiary in accordance with the terms of this Indenture; provided, however, that immediately after giving effect to such acquisition, merger, amalgamation or consolidation and the Incurrence of such Indebtedness, Disqualified Stock or
Preferred Stock on a pro forma basis, either: 
 (1) the Fixed Charge Coverage Ratio of Syniverse and its Restricted
Subsidiaries for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date of such transaction, would have been at least 2.00 to 1.00; or 

(2) the Fixed Charge Coverage Ratio of Syniverse and its Restricted Subsidiaries would be greater than immediately prior to
giving effect to such transaction; 
 provided that if any Acquisition Subsidiary shall merge, consolidate or amalgamate with or into or wind up into any
Restricted Subsidiary of the Issuer (other than the Issuer or another Acquisition Subsidiary or any of its Subsidiaries), any Indebtedness Incurred or any Disqualified Stock or Preferred Stock issued by such Acquisition Subsidiary pursuant to this
clause (o) shall be deemed an Incurrence of Indebtedness or issuance of Disqualified Stock or Preferred Stock, as the case may be, not permitted by this clause (xv); 

(xvi) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument
drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within five Business Days of its Incurrence; 

  
 82 

 (xvii) [Reserved]; 

(xviii) Contribution Indebtedness; 

(xix) Indebtedness of the Issuer or any Restricted Subsidiary of the Issuer consisting of (x) the financing of insurance

Issuer or any of its Restricted Subsidiaries constituting reimbursement obligations with respect to letters of credit, bank guarantees, performance, bid, appeal and surety bonds, completion guarantees or similar instruments issued in the ordinary
course of business, including, without limitation, letters of credit or performance or surety bonds in respect of workers’ compensation claims, health, disability or other employee benefits (whether current or former) or property, casualty or
liability insurance or self-insurance, or other Indebtedness with respect to reimbursement-type obligations regarding workers’ compensation claims; provided, however, that upon the drawing of such letters of credit under clause (ii), such
obligations are reimbursed within 30 days following such drawing; provided, further, that the aggregate principal amount of Indebtedness under the foregoing clauses (i) and (ii), including all Indebtedness Incurred to renew, refund, refinance,
replace, defease or discharge any Indebtedness Incurred pursuant to this clause (xx), shall not exceed, together with the aggregate principal amount of Indebtedness Incurred and Disqualified Stock or Preferred Stock issued under clause
(iv) above, the greater of (x) $17.5 million and (y) 2.7% of SFHC Total Assets, in each case, at the time of Incurrence, at any one time outstanding; 

(xxi) Indebtedness of a Restricted Subsidiary of the Issuer that is not a Wholly Owned Subsidiary to holders of Equity
Interests of such Restricted Subsidiary (other than the Issuer and/or its Restricted Subsidiaries), so long as the percentage of the aggregate amount of such Indebtedness of such Restricted Subsidiary owed to such holders does not exceed the
percentage of the aggregate outstanding amount of the Equity Interests of such Restricted Subsidiary held by such holders; 

(xxii) [Reserved]; 

(xxiii) Indebtedness owed on a short-term basis to banks and other financial institutions Incurred in the ordinary course of
business of the Issuer and its Restricted Subsidiaries with such banks or financial institutions that arises in connection with ordinary banking arrangements to manage cash balances of the Issuer and its Restricted Subsidiaries; 

  
 83 

 (xxiv) [Reserved]; 

(xxv) customer deposits and advance payments received in the ordinary course of business from customers for goods purchased in
the ordinary course of business; 
 (xxvi) Indebtedness incurred by the Issuer or any of its Restricted Subsidiaries in
connection with bankers’ acceptances, discounted bills of exchange or the discounting or factoring of receivables for credit management purposes, in each case incurred or undertaken in the ordinary course of business on arm’s-length
commercial terms; 
 (xxvii) Indebtedness incurred by the Issuer or any of its Restricted Subsidiaries to the extent that the
net proceeds thereof are promptly deposited with the Trustee to satisfy and discharge the Notes in accordance with this Indenture; and 

(xxviii) guarantees incurred in the ordinary course of business in respect of obligations to suppliers, customers, franchisees,
lessors and licensees that, in each case, are not Affiliates. 
 For purposes of determining compliance with this Section 3.3, in the
event that an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of more than one of the categories of Permitted Debt, the Issuer shall, in its sole discretion, at the time of Incurrence, divide,
classify or reclassify, or at any later time divide, classify or reclassify, such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) in any manner that complies with this covenant. Accrual of interest or dividends,
the accretion of accreted value, the amortization of original issue discount, the payment of interest or dividends in the form of additional Indebtedness with the same terms, the payment of dividends on Disqualified Stock or Preferred Stock in the
form of additional shares of Disqualified Stock or Preferred Stock of the same class, the accretion of liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of
currencies will not be deemed to be an Incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this covenant. Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness that are otherwise
included in the determination of a particular amount of Indebtedness shall not be included in the determination of such amount of Indebtedness; provided that the Incurrence of the Indebtedness represented by such guarantee or letter of credit, as
the case may be, was in compliance with this Section 3.3. 

  
 84 

 For purposes of determining compliance with any U.S. dollar-denominated restriction on the
Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the
case of term debt, or first committed or first Incurred (whichever yields the lower U.S. dollar-equivalent), in the case of revolving credit debt; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a
foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated
restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. If any Indebtedness is Incurred to refinance
Indebtedness initially Incurred (or, Indebtedness Incurred to refinance Indebtedness initially Incurred) in reliance on any provision of Permitted Debt measured by reference to a percentage of SFHC Total Assets at the time of Incurrence, and such
refinancing would cause such percentage of SFHC Total Assets restriction to be exceeded if calculated based on the SFHC Total Assets on the date of such refinancing, such percentage of SFHC Total Assets shall not be deemed to be exceeded (and such
refinancing Indebtedness shall be deemed permitted) so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. 

SECTION 3.4 Limitation on Restricted Payments. 

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly:

Disqualified Stock) of the Issuer; or (B) dividends or distributions by a Restricted Subsidiary of the Issuer so long as, in the case of any dividend or distribution payable on or in respect of any class or series of securities issued by a

series of securities); 
 (ii) purchase or otherwise acquire or retire for value any Equity Interests of the Issuer or
Syniverse or any other direct or indirect parent of the Issuer; 

  
 85 

 (iii) make any principal payment on, or redeem, repurchase, defease or otherwise

Indebtedness in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such payment, redemption, repurchase, defeasance, acquisition or retirement and
(B) Indebtedness permitted under clause (vii) or (ix) of the definition of “Permitted Debt”); or

Stock”) of the Issuer or Syniverse or any other direct or indirect parent of the Issuer, or Subordinated Indebtedness of the Issuer or any Guarantor that is a Subsidiary of the Issuer, in exchange for, or out of the proceeds of the
substantially concurrent sale of, Equity Interests of the Issuer or Syniverse or any other direct or indirect parent of the Issuer or contributions to the equity capital of the Issuer (other than Excluded Equity) (collectively, including any such
contributions, “SFHC Refunding Capital Stock”); and 
 (b) the declaration and payment of accrued dividends on the
SFHC Retired Capital Stock out of the proceeds of the substantially concurrent sale (other than to a Subsidiary of Syniverse or to an employee stock ownership plan or any trust established by Syniverse or any of its Subsidiaries) of SFHC Refunding
Capital Stock; 
 (iii) the redemption, repurchase, defeasance or other acquisition or retirement of Subordinated
Indebtedness of the Issuer or any Guarantor that is a Subsidiary of the Issuer made by exchange for, or out of the proceeds of the substantially concurrent sale of, Refinancing Indebtedness thereof;

tendered in connection with the Transactions; 
 (viii) [Reserved]; 

(ix) [Reserved]; 

(x) other SFHC Restricted Payments in an aggregate amount not to exceed $10.0 million at the time of such SFHC Restricted
Payment, at any one time outstanding; 
 (xi) the payment, purchase, redemption, defeasance or other acquisition or

redemption, defeasance or other acquisition or retirement for value, the Issuer (or a third party to the extent permitted by this Indenture) has made, if and to the extent required by this Indenture, a Change of Control Offer or SFHC Asset Sale
Offer, as the case may be, with respect to the Notes as a result of such Change of Control or SFHC Asset Sale, as the case may be, and has repurchased, if and to the extent required by this Indenture, all Notes validly tendered and not withdrawn in
connection with such Change of Control Offer or SFHC Asset Sale Offer, as the case may be; 
 (xii) [Reserved]; 

(xiii) [Reserved]; 

(xiv) the payment of cash dividends or other distributions on the Issuer’s Capital Stock used to, or the making of loans
to Syniverse or any other direct or indirect parent of the Issuer to, fund the payment of fees and expenses owed by the Issuer or any other direct or indirect parent or any Restricted Subsidiary of the Issuer, as the case may be, to Affiliates, in

(xviii) the distribution, as a dividend or otherwise, of shares of Capital Stock of, or Indebtedness owed to Syniverse or a

(xx) [Reserved]; and 

(xxi) SFHC Restricted Payments to Syniverse or any of its Restricted Subsidiaries; provided that (i) no Default or Event
of Default shall have occurred and be continuing or would occur as a consequence thereof and (ii) (x) immediately after giving effect to such transaction on a pro forma basis, the Fixed Charge Coverage Ratio of the Issuer and its
Restricted Subsidiaries for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such SFHC Restricted Payment is made would have been at least 1.50 to 1.00 or
(y) immediately after giving effect to such transaction, the Debt Service Reserve Account is funded in an aggregate amount equal to an amount sufficient to pay the full amount of interest on the Notes that would be payable in the next six
succeeding months; 
 provided, however, that at the time of, and after giving effect to, any SFHC Restricted Payment permitted under clauses (x),
(xi) and (xviii) of this Section 3.4(b), no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof. 

As of the Issue Date, all of the Issuer’s Subsidiaries shall be Restricted Subsidiaries. The Issuer shall not permit any Unrestricted
Entity that is a Subsidiary of the Issuer to become a Restricted Subsidiary except pursuant to the definition of “Unrestricted Entity.” For purposes of designating any Restricted Subsidiary of the Issuer as an Unrestricted Entity, all
outstanding Investments by the Issuer and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated shall 

  
 88 

 
be deemed to be SFHC Restricted Payments or SFHC Permitted Investments in an amount determined as set forth in the last sentence of the definition of “Investments.” Such designation
shall only be permitted if a SFHC Restricted Payment or SFHC Permitted Investment in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Entity. 

For purposes of this Section 3.4, if any Investment or SFHC Restricted Payment would be permitted pursuant to one or more provisions of
this Section 3.4 and/or one or more of the exceptions contained in the definition of “SFHC Permitted Investments,” the Issuer may divide and classify such Investment or SFHC Restricted Payment in any manner that complies with this
Section 3.4 and may later divide and reclassify any such Investment or SFHC Restricted Payment so long as the Investment or SFHC Restricted Payment (as so divided and/or reclassified) would be permitted to be made in reliance on the applicable
exception as of the date of such reclassification; provided that SFHC Restricted Payments made under Section 3.4(b)(x) may not later be reclassified. 

SECTION 3.5 Liens. 
 (a) The
Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist any Lien (other than Permitted Liens) on any asset or property of the Issuer or such Restricted Subsidiary, or any
income or profits therefrom, or assign or convey any right to receive income therefrom, that secures any Obligations of the Issuer or such Restricted Subsidiary, unless (1) in the case of Liens securing Subordinated Indebtedness, the Notes or
any applicable Guarantee is secured by a Lien on such assets of the Issuer or such Restricted Subsidiary and proceeds thereof that is senior in priority to such Liens; or (2) in all other cases, the Notes or the applicable Guarantee is equally
and ratably secured with or prior to such Obligation with a Lien on the same assets of the Issuer or such Restricted Subsidiary, as the case may be. 

(b) Any Lien which is granted to secure the Notes or such Guarantee under Section 3.5(a) shall be automatically released and discharged at
the same time as the release of the Lien (other than a release following enforcement of remedies in respect of such Lien or the Obligations secured by such Lien) that gave rise to the obligation to secure the Notes or such Guarantee under
Section 3.5(a). 
 SECTION 3.6 Dividend and Other Payment Restrictions Affecting Subsidiaries. The Issuer shall not, and shall not
permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary of the Issuer to:

 (a)(i) pay dividends or make any other distributions to the Issuer or any of its Restricted Subsidiaries (1) on its
Capital Stock or (2) with respect to any other interest or participation in, or measured by, its profits; or (ii) pay any Indebtedness owed to the Issuer or any of its Restricted Subsidiaries; 

  
 89 

 (b) make loans or advances to the Issuer or any of its Restricted Subsidiaries;
or 
 (c) sell, lease or transfer any of its properties or assets to the Issuer or any of its Restricted Subsidiaries; except
in each case for such encumbrances or restrictions existing under or by reason of: 
 (i) contractual encumbrances or
restrictions of the Issuer or any of its Restricted Subsidiaries in effect on the Issue Date, including pursuant to the Senior Credit Agreement, the Existing Indenture, the Existing Notes and any other documents relating thereto; 

(ii) this Indenture, the Notes (including any Exchange Notes) and Guarantees thereof; 

(iii) applicable law or any applicable rule, regulation or order; 

(iv) any agreement or other instrument of a Person acquired by the Issuer or any of its Restricted Subsidiaries which was in
existence at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of
the Person, so acquired; 
 (v) customary encumbrances or restrictions contained in contracts or agreements for the sale of
assets applicable to such assets pending consummation of such sale, including customary restrictions with respect to a Restricted Subsidiary of the Issuer imposed pursuant to an agreement entered into for the sale or disposition of all or
substantially all the Capital Stock or assets of such Restricted Subsidiary; 
 (vi) restrictions on cash or other deposits
or net worth imposed by customers under contracts entered into in the ordinary course of business; 
 (vii) customary
provisions in (x) joint venture agreements with respect to the Equity Interests subject to the joint venture and (y) operating or other similar agreements, asset sale agreements, stock sale agreements entered into in connection with the
entering into of such transaction, which limitation is applicable only to the assets that are the subject of those agreements; 

(viii) purchase money obligations for property acquired and Capitalized Lease Obligations entered into in the ordinary course
of business, to the extent such obligations impose restrictions of the nature discussed in clause (c) above on the property so acquired; 

  
 90 

 (ix) customary provisions contained in leases, licenses, contracts and other
similar agreements entered into in the ordinary course of business to the extent such obligations impose restrictions of the type described in clause (c) above on the property subject to such lease; 

(x) [Reserved]; 

(xi) other Indebtedness, Disqualified Stock or Preferred Stock of any Restricted Subsidiary of the Issuer that is Incurred
subsequent to the Issue Date pursuant to Section 3.3; provided that such encumbrances and restrictions contained in any agreement or instrument will not materially affect the Issuer’s ability to make anticipated principal or interest
payment on the Notes (as determined by the Issuer in good faith); 
 (xii) any encumbrance or restriction contained in
Secured Indebtedness otherwise permitted to be Incurred pursuant to Sections 3.3 and 3.5 to the extent limiting the right of the debtor to dispose of the assets securing such Indebtedness; 

(xiii) any encumbrance or restriction arising or agreed to in the ordinary course of business, not relating to any
Indebtedness, and that does not, individually or in the aggregate, (x) detract from the value of the property or assets of the Issuer or any of its Restricted Subsidiaries in any manner material to the Issuer or any such Restricted Subsidiary
or (y) materially affect the Issuer’s ability to make future principal or interest payments on the Notes, in each case, as determined by the Issuer in good faith; 

(xiv) customary provisions in joint venture agreements and other similar agreements relating solely to the applicable joint
venture; 
 (xv) existing under, by reason of or with respect to Refinancing Indebtedness; provided that the encumbrances and
restrictions contained in the agreements governing that Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; 

(xvi) applicable law or any applicable rule, regulation or order in any jurisdiction where Indebtedness, Disqualified Stock or
Preferred Stock of Foreign Subsidiaries permitted to be Incurred pursuant to Section 3.3; and 

  
 91 

 (xvii) any encumbrances or restrictions imposed by any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (i) through (xvi) above; provided that any such amendment, modification,
restatement, renewal, increase, supplement, refunding, replacement or refinancing is, in the good faith judgment of the Issuer, no more restrictive as a whole with respect to the applicable encumbrance or restriction than prior to such amendment,
modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing. 
 For purposes of determining compliance
with this Section 3.6, (i) the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock shall not be deemed a restriction on the ability
to make distributions on Capital Stock and (ii) the subordination of loans or advances made to the Issuer or a Restricted Subsidiary of the Issuer to other Indebtedness Incurred by the Issuer or any such Restricted Subsidiary shall not be
deemed a restriction on the ability to make loans or advances. 
 SECTION 3.7 Asset Sales. 

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, cause or make a SFHC Asset Sale, unless: 

(i) immediately after giving effect to such transaction on a pro forma basis, the Fixed Charge Coverage Ratio of the Issuer and
its Restricted Subsidiaries for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such SFHC Asset Sale is committed to be consummated would have been at
least 1.50 to 1.00; 
 (ii) the Issuer or any of its Restricted Subsidiaries, as the case may be, receives consideration at
the time of such SFHC Asset Sale at least equal to the Fair Market Value (as determined in good faith by the Issuer) of the assets sold or otherwise disposed of; and 

(iii) except in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by the Issuer or such
Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents or Replacement Assets; provided, however that the amount of: 

(1) any liabilities (as shown on the Issuer’s or such Restricted Subsidiary’s most recent balance sheet or in the
notes thereto) of the Issuer or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee of any such assets or Equity Interests pursuant to an agreement that releases or
indemnifies the Issuer or such Restricted Subsidiary, as the case may be, from further liability; 

  
 92 

 (2) any notes or other obligations or other securities or assets received by the
Issuer or such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the cash received); and 

(3) any SFHC Designated Non-cash Consideration received by the Issuer or any of its Restricted Subsidiaries in such SFHC Asset
Sale having an aggregate Fair Market Value, taken together with all other SFHC Designated Non-cash Consideration received pursuant to this clause (3) that is at that time outstanding, not to exceed the greater of (x) $25.0 million and
(y) 3.8% of SFHC Total Assets, at the time of the receipt of such SFHC Designated Non-cash Consideration (with the Fair Market Value of each item of SFHC Designated Non-cash Consideration being measured at the time received and without giving
effect to subsequent changes in value); 
 shall each be deemed to be Cash Equivalents for the purposes of this clause (iii). 

(b) Within 365 days after the Issuer’s or any of its Restricted Subsidiaries’ receipt of the Net Cash Proceeds of any SFHC Asset
Sale, the Issuer or such Restricted Subsidiary may apply the Net Cash Proceeds from such SFHC Asset Sale, at its option: 

(i) to permanently reduce Obligations under any Secured Indebtedness of the Issuer or any of its Restricted Subsidiaries, the
Senior Credit Agreement, any Indebtedness that serves to refund, refinance, replace, redeem, repurchase, retire or defease the Senior Credit Agreement and/or any Indebtedness Incurred to refund, refinance, replace, redeem, repurchase, retire or
defease such Indebtedness, and, in the case of revolving obligations thereunder, to correspondingly reduce commitments with respect thereto; 

(ii) to make an Investment in any one or more businesses (provided that if such investment is in the form of the acquisition of
Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of the Issuer), assets, property or capital expenditures, in each case used or useful in a Similar Business of the Issuer and its Restricted
Subsidiaries; 
 (iii) to make an Investment in any one or more businesses (provided that if such Investment is in the form
of the acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of the Issuer), properties or assets that replace the properties and assets that are the subject of such SFHC Asset Sale; or

  
 93 

 (iv) any combination of the foregoing; 

provided that the Issuer and its Restricted Subsidiaries shall be deemed to have complied with clauses (ii) and (iii) of this Section 3.7(b) if
and to the extent that, within 365 days after the SFHC Asset Sale that generated the Net Cash Proceeds, the Issuer has entered into and not abandoned or rejected a binding agreement to acquire the assets or Capital Stock of a Similar Business, make
an Investment in Replacement Assets or make a capital expenditure in compliance with clauses (ii) and (iii) of this Section 3.7(b), and that acquisition, purchase or capital expenditure is thereafter completed within 180 days after
the end of such 365-day period. 
 (c) Pending the final application of any such Net Cash Proceeds, the Issuer or such Restricted Subsidiary
of the Issuer may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Cash Proceeds in Cash Equivalents. Any Net Cash Proceeds from any SFHC Asset Sale that are not applied as provided and within
the time period set forth in Section 3.7(b) will be deemed to constitute “SFHC Excess Proceeds.” When the aggregate amount of SFHC Excess Proceeds exceeds $10.0 million, the Issuer shall: 

(i) first, to the extent required under any Secured Indebtedness of the Issuer or any of its Restricted Subsidiaries, the
Senior Credit Agreement, the Existing Indenture, any Indebtedness that serves to refund, refinance, replace, redeem, repurchase, retire or defease the Senior Credit Agreement and/or any Indebtedness Incurred to refund, refinance, replace, redeem,
repurchase, retire or defease such Indebtedness, use such SFHC Excess Proceeds to repay Indebtedness, reduce commitments and/or make an offer to repurchase Indebtedness, commitments and/or notes outstanding under such Secured Indebtedness, the
Senior Credit Agreement, the Existing Indenture and/or any such Indebtedness; and 
 (ii) second, to the extent permitted
under any Secured Indebtedness of the Issuer or any of its Restricted Subsidiaries, the Senior Credit Agreement, the Existing Indenture, any Indebtedness that serves to refund, refinance, replace, redeem, repurchase, retire or defease the Senior
Credit Agreement and/or the Existing Indenture and any Indebtedness Incurred to refund, refinance, replace, redeem, repurchase, retire or defease such Indebtedness, make an offer (a “SFHC Asset Sale Offer”) to all Holders of Initial Notes
(including any Exchange Notes in respect thereof) and all Holders of any Additional Notes (including any Exchange Notes in respect thereof and any other Notes issued in respect thereof pursuant to Section 2.6, 2.7, 2.10, 3.7, 3.9, 3.18 or 9.4
or Article V) to purchase the maximum principal amount of such Initial Notes and such Additional Notes,

on a pro rata basis, that may be purchased out of the SFHC Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest
and Additional Interest, if any, to, but excluding, the date fixed for the closing of such offer (or such lesser price, if any, as may be provided by the terms of such Additional Notes), in accordance with the procedures set forth in this Indenture.

 To the extent required by Section 3.7(c)(ii), the Issuer will commence a SFHC Asset Sale Offer with respect to SFHC Excess Proceeds
within ten days after the later of the date of the application of such SFHC Excess Proceeds pursuant to Section 3.7(c)(i) and the date that such SFHC Excess Proceeds exceed $10.0 million by sending the notice required pursuant to the terms of
this Indenture, with a copy to the Trustee. To the extent that the aggregate amount of such Initial Notes and such Additional Notes tendered pursuant to a SFHC Asset Sale Offer is less than the SFHC Excess Proceeds, the Issuer may use any remaining
SFHC Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of such Initial Notes and such Additional Notes surrendered by Holders thereof exceeds the amount of SFHC Excess Proceeds, the Trustee
shall select the Notes to be purchased in the manner described below. Upon completion of any such SFHC Asset Sale Offer, the amount of SFHC Excess Proceeds shall be reset at zero. 

(d) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the
extent such laws or regulations are applicable in connection with the purchase of the Notes pursuant to a SFHC Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture,
the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. 

(e) If more Notes are tendered pursuant to a SFHC Asset Sale Offer than the Issuer is required to purchase, selection of such Notes for
purchase will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed (so long as the Trustee knows of such listing) or if such Notes are not listed, on a pro
rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements, and, in the case of Global Notes, the procedures of the Depositary); provided, that the
selection of Notes for purchase shall not result in a Holder with a principal amount of Notes less than the Minimum Denomination. 
 (f)
Notices of a SFHC Asset Sale Offer shall be sent at least 30 but not more than 60 days before the Purchase Date to each Holder of the Notes electronically, by first class mail to its registered address or otherwise in accordance with the procedures
of the Depositary. If any Note is to be purchased in part only, any notice of purchase that relates to such Note shall state the portion of the principal amount thereof that has been or is to be purchased. 

  
 95 

 A new Note in principal amount equal to the unpurchased portion of any Note purchased in part
will be issued in the name of the Holder thereof upon cancellation of the original Note (or if the Note is a Global Note, an adjustment shall be made to the “Schedule of Increases or Decreases in Global Note” attached thereto). On and
after the Purchase Date, unless the Issuer defaults in payment of the purchase price, interest shall cease to accrue on Notes or portions thereof purchased.

guarantee with, or for the benefit of, any Affiliate of the Issuer (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration in excess of $7.5 million, unless: 

(i) such Affiliate Transaction is on terms that are not materially less favorable to the Issuer or the relevant Restricted
Subsidiary than those that could have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person; and 

(ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $15.0 million, the Issuer delivers to the Trustee a resolution adopted in good faith by the majority of the Board of Directors of the Issuer, approving such Affiliate Transaction and an Officer’s Certificate certifying that such
Affiliate Transaction complies with clause (i) above. 
 (b) The provisions of Section 3.8(a) will not apply to the following: 

(i)(a) transactions between or among the Issuer and/or any of its Restricted Subsidiaries (or an entity that becomes a
Restricted Subsidiary of SFHC as a result of such transaction) and (b) any merger or consolidation of the Issuer and any direct parent of the Issuer; provided that such parent company shall have no material liabilities and no material assets

(v) payments or loans (or cancellation of loans, advances or guarantees) or advances to employees or consultants or guarantees
in respect thereof for bona fide business purposes in the ordinary course of business; 
 (vi) any agreement as in effect as
of the Issue Date or as thereafter amended, supplemented or replaced (so long as such amendment, supplement or replacement agreement is not more disadvantageous to the Holders of the Notes in any material respect than the original agreement as in
effect on the Issue Date) or any transaction or payments contemplated thereby; 
 (vii) the Management Agreement as in effect
as of the Issue Date or as thereafter amended, supplemented or replaced (so long as such amendment, supplement or replacement agreement is not more disadvantageous to the Holders of the Notes in any material respect than the Management Agreement as
in effect on the Issue Date) or any transaction or payments (including reimbursement of out-of-pocket expenses) contemplated thereby; 

(viii) any transaction between the Issuer and/or any of its Restricted Subsidiaries, on the one hand, and Syniverse and/or any
of its Restricted Subsidiaries, on the other hand, so long as such transaction is made in the ordinary course of business and consistent with past practice, which is fair to the Issuer and its Restricted Subsidiaries in the reasonable determination
of the Board of Directors or the senior management of the Issuer;

(xiii) any contribution to the capital of the Issuer (other than Disqualified Stock); 

(xiv) any transaction with a Person (other than an Unrestricted Entity) that would constitute an Affiliate Transaction solely

Issuer shall have a beneficial interest or otherwise participate in such Person; 
 (xv) transactions between the Issuer or
any of its Restricted Subsidiaries and any Person, a director of which is also a director of the Issuer or any direct or indirect parent of the Issuer; provided, however, that such director abstains from voting as a director of the Issuer or such

(xxi) transactions with Affiliates solely in their capacity as holders of Indebtedness or preferred Equity Interests of the

(xxii) investments by the Sponsor in securities of the Issuer or any of its Restricted Subsidiaries (and payment of reasonable
out-of-pocket expenses incurred by the Sponsor in connection therewith). 
 SECTION 3.9 Change of Control. 

(a) Upon the occurrence of a Change of Control, each Holder will have the right to require the Issuer to purchase all or any part of such
Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to, but excluding, the date of purchase (subject to the right of Holders of record on
the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date), except to the extent the Issuer has previously elected to redeem the Notes pursuant to Article V of this Indenture. 

(b) Prior to or within 30 days following any Change of Control, except to the extent that the Issuer has exercised its right to redeem the
Notes pursuant to Article V, the Issuer shall send a notice (a “Change of Control Offer”) to each Holder with a copy to the Trustee describing: 

(i) that a Change of Control has occurred or may occur and that such Holder has the right to require the Issuer to purchase
such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to, but excluding, the date of purchase (subject to the right of Holders of record
on a Regular Record Date to receive interest on the relevant Interest Payment Date); 

  
 99 

 (ii) the transaction or transactions that constitute, or are expected to
constitute, such Change of Control; 
 (iii) the purchase date (which shall be no earlier than 30 days nor later than 60 days
from the date such notice is sent, except that such notice may be given more than 60 days prior to the Change of Control Purchase Date if the Change of Control Purchase Date is delayed as provided in Section 3.9(b)(iv)) (the “Change of
Control Purchase Date”); 
 (iv) if such notice is sent prior to the occurrence of a Change of Control, stating that the
Change of Control Offer is conditional on the occurrence of such Change of Control pursuant to Section 3.9(h) and that the Change of Control Purchase Date may, in the Issuer’s discretion, be delayed until such time as the Change of Control
has occurred; and 
 (v) the instructions determined by the Issuer, consistent with this Section 3.9, that a Holder must
follow in order to have its Notes purchased. 
 (c) Holders electing to have a Note purchased shall be required to surrender the Note, with
an appropriate form duly completed, to the applicable Agent or the Issuer at the address specified in the notice at least three Business Days prior to the Change of Control Purchase Date. Holders shall be entitled to withdraw their election if the
applicable Agent or the Issuer receives prior to the expiration of the Change of Control Offer, a telegram, facsimile transmission, letter or electronic transmission in the form of a “pdf” on letterhead (if applicable) and signed by an
authorized signer setting forth the name of the Holder, the principal amount at maturity of the Note which was delivered for purchase by the Holder and a statement that such Holder is withdrawing his selection to have such Note purchased. 

(d) On the purchase date, all Notes purchased by the Issuer under this Section 3.9 shall be delivered by the applicable Agent or the
Issuer to the Trustee for cancellation, and the Issuer shall pay the purchase price plus accrued and unpaid interest and Additional Interest, if any, to the Holders entitled thereto. With respect to any Note purchased in part, the Issuer shall
issue, and the Trustee shall authenticate, a new Note in a principal amount equal at maturity to the unpurchased portion of the original Note in the name of the Holder upon cancellation of the original Note (or if the Note is a Global Note, an
adjustment shall be made to the “Schedule of Increases or Decreases in Global Note” attached thereto). 
 (e) Notwithstanding the
provisions of this Section 3.9, the Issuer shall not be required to make a Change of Control Offer upon a Change of Control if a third party 

  
 100 

 
makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the
Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. 
 (f) Prior to any Change of Control
Offer, the Issuer shall deliver to the Trustee an Officer’s Certificate stating that all conditions precedent contained herein to the right of the Issuer to make such offer have been complied with. 

(g) The Issuer shall comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities laws or
regulations in connection with the repurchase of Notes pursuant to this Section 3.9. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 3.9, the Issuer shall comply with the
applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 3.9 by virtue of such compliance. 

(h) A Change of Control Offer may be made in advance of a Change of Control and conditioned upon such Change of Control. 

SECTION 3.10 [Reserved]. 

SECTION 3.11 Future Guarantors. If, after the Issue Date, (a) any Restricted Subsidiary of Syniverse (including any newly formed, newly
acquired or newly redesignated Restricted Subsidiary thereof) that is not then a Guarantor guarantees any Indebtedness under the Senior Credit Agreement or the Existing Indenture or (b) the Issuer otherwise elects to have any Restricted
Subsidiary of Syniverse become a Guarantor, then, in each such case, the Issuer shall cause such Restricted Subsidiary, within 20 Business Days of the date that such Indebtedness has been guaranteed (in the case of clause (a) only), to execute
and deliver to the Trustee a Guarantor Supplemental Indenture pursuant to which such Restricted Subsidiary shall become a Guarantor under this Indenture. 

Each Guarantee will be limited to an amount not to exceed the maximum amount that can be guaranteed by that Restricted Subsidiary without
rendering the Guarantee, as it relates to such Restricted Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

Each Guarantee shall be released in accordance with Section 10.2. 

SECTION 3.12 Compliance Certificate; Statement by Officers as to Default. The Issuer shall deliver to the Trustee, within 120 days after the
end of each fiscal year of the Issuer ending after the Issue Date, an Officer’s Certificate to the effect that to the best 

  
 101 

 
knowledge of the signer thereof on behalf of the Issuer, the Issuer is or is not in default in the performance and observance of any of the terms, provisions and conditions of this Indenture
(without regard to any period of grace or requirement of notice provided hereunder) and, if the Issuer (through its own action or omission or through the action or omission of any Guarantor as applicable) shall be in default, specifying all such
defaults and the nature and status thereof of which such signer may have knowledge. Following the qualification of this Indenture under the TIA, (i) each Guarantor shall, to the extent required by the TIA, comply with TIA § 314(a)(4), and
(ii) the individual signing any certificate given by any Person pursuant to this Section 3.12 shall be the principal executive, financial or accounting officer of such Person, in compliance with TIA § 314(a)(4). 

So long as any of the Notes are outstanding, the Issuer will deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto. 

SECTION 3.13 Limitation on Layering. 

Notwithstanding anything to the contrary in this Indenture, the Issuer shall not, and shall not permit any Guarantor that is a Subsidiary of
the Issuer to, directly or indirectly, Incur any Indebtedness (including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of the Issuer or such Guarantor, as the case may be, unless such Indebtedness is
expressly subordinated in right of payment to the Notes or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Issuer or such Guarantor, as the case may be. Unsecured
Indebtedness shall not be treated as subordinated or junior to Secured Indebtedness merely because it is unsecured, and Indebtedness shall not be treated as subordinated or junior to any other Indebtedness merely because it has a junior priority
with respect to the same collateral. 
 SECTION 3.14 Designation of Restricted and Unrestricted Entities. 

(a) The Board of Directors of the Issuer or Syniverse, as applicable, may designate any Subsidiary of the Issuer or Syniverse, respectively
(including any newly acquired or newly formed Subsidiary of the Issuer or Syniverse but excluding the Issuer or Syniverse, as applicable), to be an Unrestricted Entity unless such Subsidiary or any of its Subsidiaries owns any Equity Interests or
Indebtedness of, or owns or holds any Lien on any property of, the Issuer or Syniverse, as applicable, or any other Subsidiary of the Issuer or Syniverse, as applicable, that is not a Subsidiary of the Subsidiary to be so designated; provided,
however, that the Subsidiary to be so designated and its Subsidiaries do not at the time of designation have and do not thereafter Incur any Indebtedness pursuant to which the lender has recourse to any of the assets of the Issuer

  
 102 

 
or any of its Restricted Subsidiaries or Syniverse or any of its Restricted Subsidiaries, as applicable; provided, further, however, that either: 

(i) the Subsidiary to be so designated has total consolidated assets of $1,000 or less; or 

(ii) if such Subsidiary has consolidated assets greater than $1,000, then such designation would be permitted under
Section 3.4 or 3.17, as applicable. 
 (b) The Board of Directors of the Issuer or Syniverse, as applicable, may designate any
Unrestricted Entity to be a Restricted Subsidiary; provided, however, that immediately after giving effect to such designation: 

(x)(1) the Fixed Charge Coverage Ratio of the Issuer and its Restricted Subsidiaries or Syniverse and its Restricted
Subsidiaries, as applicable, for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date of such designation, would have been at least 2.00 to 1.00, or 

(2) the Fixed Charge Coverage Ratio for the Issuer and its Restricted Subsidiaries or Syniverse and its Restricted
Subsidiaries, as applicable, would be greater than such ratio for the Issuer and its Restricted Subsidiaries or Syniverse and its Restricted Subsidiaries, as applicable, immediately prior to giving effect to such designation, 

in each case on a pro forma basis taking into account such designation, and 

(y) no Event of Default shall have occurred and be continuing. 

(c) Any such designation by the Board of Directors of the Issuer or Syniverse, as applicable, shall be evidenced to the Trustee by promptly
filing with the Trustee a copy of the resolution of the Board of Directors of the Issuer or Syniverse, as applicable, giving effect to such designation and an Officer’s Certificate of the Issuer or Syniverse, as applicable, certifying that such
designation complied with this Section 3.14. 
 SECTION 3.15 Covenant Suspension. 

(a) If on any date following the Issue Date (i) the Notes have Investment Grade Ratings from both Rating Agencies, and (ii) no
Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), Sections 3.3, 3.4, 3.6,
3.7, 3.8, 3.17. 3.18 and 4.2(a)(iv) (collectively, the “Suspended Covenants”) shall no longer be applicable to such Notes. 

  
 103 

 (b) In the event that the Issuer, Syniverse and their respective Restricted Subsidiaries are not
subject to the Suspended Covenants under this Indenture for any period of time pursuant to Section 3.15(a), and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade Rating or
downgrade the rating assigned to the Notes below an Investment Grade Rating, then the Issuer, Syniverse and their respective Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants under this Indenture with respect to
future events. The period of time between the occurrence of a Covenant Suspension Event and the Reversion Date is referred to in this Indenture as the “Suspension Period.” 

(c) Upon the occurrence of a Covenant Suspension Event, the amount of SFHC Excess Proceeds and Syniverse Excess Proceeds from Net Cash Proceeds
shall be reset at zero. 
 (d) In the event of any reinstatement of the Suspended Covenants pursuant to Section 3.15(b), no failure to
comply with the Suspended Covenants prior to such reinstatement will give rise to a Default or Event of Default under this Indenture with respect to the Notes; provided that (1) with respect to SFHC Restricted Payments or Syniverse Restricted
Payments, as applicable, made after the Reversion Date, the amount of SFHC Restricted Payments or Syniverse Restricted Payments, as applicable, made shall be calculated as though Section 3.4 and Section 3.17 had been in effect prior to,
but not during, the Suspension Period; provided that no Subsidiaries of Syniverse may be designated as Unrestricted Entities during the Suspension Period unless such designation would have complied with Section 3.4 or Section 3.17, as
applicable, as if such Section 3.4 or Section 3.17 were in effect during such period, and (2) all Indebtedness Incurred, or Disqualified Stock or Preferred Stock issued, by the Issuer or any of its Restricted Subsidiaries during the
Suspension Period shall be classified to have been Incurred or issued pursuant to Section 3.3(b)(iii). In addition, for purposes of Section 3.8, all agreements and arrangements entered into by the Issuer and any Restricted Subsidiary
thereof with an Affiliate of the Issuer during the Suspension Period prior to such Reversion Date will be deemed to have been entered into on or prior to the Issue Date, and for purposes of Section 3.6, all contracts entered into during the
Suspension Period prior to such Reversion Date that contain any of the restrictions contemplated by such Section 3.6 will be deemed to have been existing on the Issue Date. 

The Issuer shall provide an Officer’s Certificate to the Trustee indicating the occurrence of any Covenant Suspension Event or Reversion
Date. The Trustee will have no obligation to (i) independently determine or verify if such events have occurred, (ii) make any determination regarding the impact of actions taken during the Suspension Period on the Issuer, Syniverse and
their respective Subsidiaries’ future compliance with their covenants or (iii) notify the Holders of any Covenant Suspension Event or Reversion Date. 

  
 104 

 SECTION 3.16 Stay, Extension and Usury Laws. The Issuer and each of the Guarantors covenant (to
the extent that they may lawfully do so) that they shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in
force, that may affect the covenants or the performance of this Indenture; and the Issuer and each of the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenant that they
shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. 

SECTION 3.17 Limitation on Restricted Payments Applicable to Syniverse and Its Restricted Subsidiaries (Other than the Issuer and its
Restricted Subsidiaries). 
 (a) Syniverse shall not, and shall not permit any of its Restricted Subsidiaries (other than the Issuer and its
Restricted Subsidiaries) to, directly or indirectly: 
 (i) declare or pay any dividend or make any distribution on account
of Syniverse’s or any of its Restricted Subsidiaries’ (other than the Issuer and its Restricted Subsidiaries) Equity Interests, including any payment made in connection with any merger or consolidation involving Syniverse (other than
(A) dividends or distributions by Syniverse payable solely in Equity Interests (other than Disqualified Stock) of Syniverse); or (B) dividends or distributions by a Restricted Subsidiary of Syniverse so long as, in the case of any dividend
or distribution payable on or in respect of any class or series of securities issued by such Restricted Subsidiary other than a Wholly Owned Restricted Subsidiary, Syniverse or a Restricted Subsidiary of Syniverse receives at least its pro rata
share of such dividend or distribution in accordance with its Equity Interests in such class or series of securities); 

(ii) purchase or otherwise acquire or retire for value any Equity Interests of Syniverse or any direct or indirect parent of
Syniverse; 
 (iii) make any principal payment on, or redeem, repurchase, defease or otherwise acquire or retire for value,
in each case prior to any scheduled repayment or scheduled maturity, any Subordinated Indebtedness (other than the payment, redemption, repurchase, defeasance, acquisition or retirement of (A) Subordinated Indebtedness in anticipation of
satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such payment, redemption, repurchase, defeasance, acquisition or retirement) and (B) Subordinated Indebtedness of
Syniverse or a Restricted Subsidiary to Syniverse or another Restricted Subsidiary); or 
 (iv) make any Restricted
Investment; 

  
 105 

 (all such payments and other actions set forth in clauses (i) through (iv) above being collectively
referred to as “Syniverse Restricted Payments”), unless, at the time of such Syniverse Restricted Payment: 
 (A)
no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof; 
 (B)
immediately after giving effect to such transaction on a pro forma basis, the Fixed Charge Coverage Ratio of Syniverse and its Restricted Subsidiaries for the most recently ended four full fiscal quarters for which internal financial statements are
available immediately preceding the date of such transaction would have been at least 2.00 to 1.00; and 
 (C) such Syniverse
Restricted Payment, together with the aggregate amount of all other Syniverse Restricted Payments made by Syniverse and its Restricted Subsidiaries (other than the Issuer and its Restricted Subsidiaries) after the Issue Date (including Syniverse
Restricted Payments permitted by clauses (i) and (viii) of Section 3.17(b), but excluding all other Syniverse Restricted Payments permitted by Section 3.17(b)), is less than the sum of, without duplication, 

(1) 100% of the EBITDA of Syniverse for the period (taken as one accounting period) from January 1, 2017 to the end of
Syniverse’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Syniverse Restricted Payment less the product of 1.4 times the Consolidated Interest Expense of Syniverse for the same
period, plus 
 (2) 100% of the aggregate net proceeds, including cash and the Fair Market Value of assets other than cash,

(3) 100% of the aggregate amount of contributions to the capital of Syniverse received in cash and the Fair Market Value of
assets other than cash after the Issue Date (other than Excluded Equity), plus 
 (4) the principal amount of any
Indebtedness, or the liquidation preference or maximum fixed repurchase price, as the case may be, of any Disqualified Stock, in each case, of Syniverse or any Restricted Subsidiary thereof issued after the Issue Date (other than Indebtedness or
Disqualified Stock issued to a Restricted Subsidiary or an employee stock ownership plan or trust established by Syniverse or any Restricted Subsidiary (other 

  
 106 

 
than to the extent such employee stock ownership plan or trust has been funded by Syniverse or any Restricted Subsidiary)) that, in each case, has been converted into or exchanged for Equity
Interests in Syniverse or any direct or indirect parent of Syniverse (other than Excluded Equity), plus 
 (5) 100% of the
aggregate amount received by Syniverse or any Restricted Subsidiary thereof in cash and the Fair Market Value of assets other than cash received by Syniverse or any Restricted Subsidiary from: 

(A) the sale or other disposition (other than to Syniverse or a Subsidiary of Syniverse) of Restricted Investments made by
Syniverse and its Restricted Subsidiaries and from repurchases and redemptions of such Restricted Investments from Syniverse and its Restricted Subsidiaries by any Person (other than Syniverse or any of its Subsidiaries) and from repayments of loans
or advances which constituted Restricted Investments (other than in each case to the extent that the Restricted Investment was made pursuant to Section 3.17(b)(x)), 

(B) the sale (other than to Syniverse or a Restricted Subsidiary thereof or an employee stock ownership plan or trust
established by Syniverse or any Restricted Subsidiary thereof (other than to the extent such employee stock ownership plan or trust has been funded by Syniverse or any Restricted Subsidiary thereof)) of the Capital Stock of an Unrestricted Entity
that is a Subsidiary of Syniverse, or 
 (C) any distribution or dividend from an Unrestricted Entity (to the extent such
distribution or dividend is not already included in the calculation of Consolidated Net Income), plus 
 (6) in the event any
Unrestricted Entity that is a Subsidiary of Syniverse has been redesignated as a Restricted Subsidiary or has been merged or consolidated with or into, or transfers or conveys its assets to, or is liquidated into, Syniverse or a Restricted
Subsidiary of Syniverse, in each case after the Issue Date, the Fair Market Value of the Investment of Syniverse or its Restricted Subsidiary in such Unrestricted Entity at the time of such redesignation, combination or transfer (or of the assets
transferred or conveyed, as applicable), after deducting any Indebtedness associated with the Unrestricted Entity so designated or combined or any Indebtedness associated with the assets so transferred or conveyed (other than in each case to the
extent that the designation of such Subsidiary as an Unrestricted Entity was made pursuant to Section 3.17(b)(x) or constituted a Syniverse Permitted Investment), plus

on a pro forma basis, the Consolidated Senior Debt Ratio of Syniverse and its Restricted Subsidiaries is less than 6.00 to 1.00. 
 (b) The
provisions of Section 3.17(a) shall not prohibit:

thereon was permitted under Section 3.17(b)(vi) and has not been made as of such time (the “Unpaid Amount”), the declaration and payment of dividends on the Syniverse Refunding Capital Stock (other than Syniverse Refunding Capital
Stock the proceeds of which were used to redeem, repurchase, retire or otherwise acquire any Equity Interests of Syniverse or any direct or indirect parent of Syniverse) in an aggregate amount no greater than the Unpaid Amount; 

(iii) the redemption, repurchase, defeasance or other acquisition or retirement of Subordinated Indebtedness of Syniverse or
any Guarantor made by exchange for, or out of the proceeds of the substantially concurrent sale of, Refinancing Indebtedness thereof; 

  
 108 

 (iv) the purchase, retirement, redemption or other acquisition (or dividends to
any direct or indirect parent of Syniverse to finance any such purchase, retirement, redemption or other acquisition) for value of Equity Interests of Syniverse or any direct or indirect parent of Syniverse held by any future, present or former
employee, director or consultant of Syniverse or any direct or indirect parent of Syniverse or any Subsidiary of Syniverse (or their permitted transferees) pursuant to any management equity plan or stock option plan or any other management or
employee benefit plan or other agreement or arrangement; provided, however, that the aggregate amounts paid under this clause (iv) shall not exceed (x) $10.0 million in any calendar year or (y) subsequent to the consummation of an
underwritten public Equity Offering of common stock of Syniverse or any direct or indirect parent of Syniverse or any Restricted Subsidiary of Syniverse (an “IPO”), $20.0 million in any calendar year (with unused amounts in any calendar
year being permitted to be carried over for the next two succeeding calendar years up to a maximum of (1) $15.0 million in the aggregate in any calendar year or (2) subsequent to the consummation of an IPO, $25.0 million in any calendar
year); provided, further, however, that such amount in any calendar year may be increased by an amount not to exceed: 
 (a)
the cash proceeds received by Syniverse or any of its Restricted Subsidiaries from the sale of Equity Interests of Syniverse or any direct or indirect parent of Syniverse (to the extent contributed to Syniverse) to members of management, directors

 109 

 (d) the amount of cash proceeds described in clause (a) or (b) of this

transferees thereof) of Syniverse or any of its Restricted Subsidiaries (or any direct or indirect parent company thereof), in connection with a repurchase of Equity Interests of Syniverse from such Persons will not be deemed to constitute a
Syniverse Restricted Payment for purposes of this Section 3.17 or any other provisions of this Indenture; 
 (v) the
declaration and payment of dividends or distributions to holders of any class or series of Disqualified Stock of Syniverse or any of its Restricted Subsidiaries and any Preferred Stock of any Restricted Subsidiaries issued or Incurred in accordance

internal financial statements are available immediately preceding the date of issuance of such Designated Preferred Stock, after giving effect to such issuance (and the payment of dividends or distributions) on a pro forma basis, the Fixed Charge
Coverage Ratio of Syniverse and its Restricted Subsidiaries would have been at least 2.00 to 1.00 and (B) the aggregate amount of dividends declared and paid pursuant to this clause (vi) does not exceed the net cash proceeds actually
received by Syniverse from the sale (or the contribution of the net cash proceeds from the sale) of Designated Preferred Stock; 

(vii) any Syniverse Restricted Payments made in connection with the consummation of the Transactions, including any payments or
loans made to any direct or indirect parent of Syniverse to enable it to make any such payments, and the satisfaction and discharge of the Existing Notes tendered in connection with the Transactions;

indirect parent of Syniverse to fund the payment by any direct or indirect parent of Syniverse of dividends on such entity’s common stock) of up to 6.0% per annum of the net cash proceeds received by Syniverse from any public offering of

value, Syniverse (or a third party to the extent permitted by this Indenture) has made, if and to the extent required by this Indenture, a Change of Control Offer or Syniverse Asset Sale Offer, as the case may be, with respect to the Notes as a
result of such Change of Control or Syniverse Asset Sale, as the case may be, and has, if and to the extent required by this Indenture, repurchased all Notes validly tendered and not withdrawn in connection with such Change of Control Offer or
Syniverse Asset Sale Offer, as the case may be;

other parent company to pay federal, state and local income taxes imposed on such entity to the extent such income taxes are attributable to the income of Syniverse and its Subsidiaries; provided, however, that (i) the amount of such payments
in respect of any tax year does not, in the aggregate, exceed the amount that Syniverse and its Subsidiaries that are members of such consolidated or combined group would have been required to pay in respect of federal, state and local income taxes
(as the case may be) in respect of such year if Syniverse and its Subsidiaries paid such income taxes directly as a stand-alone consolidated or combined income tax group (reduced by any such taxes paid directly by Syniverse or any Subsidiary) and
(ii) the permitted payment pursuant to this clause (xii) with respect to any taxes attributable to income of any Unrestricted Entity that is a Subsidiary of Syniverse for any taxable period shall be limited to the amount actually paid with
respect to such period by such Unrestricted Entity to Syniverse or any Restricted Subsidiary of Syniverse for the purposes of paying such consolidated, combined or similar taxes; 

  
 111

(including franchise or similar taxes) required to maintain its corporate existence, customary salary, bonus and other benefits payable to, and indemnities provided on behalf of, officers and employees of any direct or indirect parent of Syniverse,
if applicable, and general corporate operating and overhead expenses of any direct or indirect parent of Syniverse, if applicable, in each case to the extent such fees, expenses, salaries, bonuses, benefits and indemnities are attributable to the
ownership or operation of Syniverse and its Subsidiaries; 
 (b) pay, if applicable, amounts equal to amounts required for
any direct or indirect parent of Syniverse to pay interest and/or principal on Indebtedness the proceeds of which have been contributed to Syniverse (other than as Excluded Equity) and that has been guaranteed by, and is otherwise considered
Indebtedness of, Syniverse or any Restricted Subsidiary thereof Incurred in accordance with Section 3.3 of the Existing Indenture (as in effect on the Issue Date) (except to the extent any such payments have otherwise been made by any such
guarantor); 
 (c) pay fees and expenses incurred by any direct or indirect parent of Syniverse, other than to Affiliates of
Syniverse, related to any unsuccessful equity or debt offering of such parent; and

as in effect on the Issue Date) or (ii) for any other financial advisory, financing, underwriting or placement services or in respect of other investment banking activities, including, without limitation, in connection with acquisitions or
divestitures, including in connection with the consummation of the Transactions, which payments are (x) made pursuant to agreements with the Sponsor described in the Offering Memorandum or (y) approved by a majority of the Board of
Directors of Syniverse in good faith; 

  
 112 

 (xiv) the payment of cash dividends or other distributions on Syniverse’s

to Affiliates, in each case to the extent permitted by Section 3.8 of the Existing Indenture (as in effect on the Issue Date); 

(xv)(a) repurchases of Equity Interests deemed to occur upon exercise of stock options or warrants if such Equity Interests
represent a portion of the exercise price of such options or warrants and (b) in connection with the withholding of a portion of the Equity Interests granted or awarded to a director or an employee to pay for the taxes payable by such director
or employee upon such grant or award; 
 (xvi) purchases of receivables pursuant to a Receivables Repurchase Obligation in
connection with a Qualified Receivables Financing and the payment or distribution of Receivables Fees; 
 (xvii) payments or
distributions to satisfy dissenters’ rights, pursuant to or in connection with a consolidation, merger or transfer of assets that complies with the provisions of this Indenture applicable to mergers, consolidations and transfers of all or
substantially all the property and assets of Syniverse; 
 (xviii) the distribution, as a dividend or otherwise, of shares of
Capital Stock of, or Indebtedness owed to Syniverse or a Restricted Subsidiary of Syniverse by, Unrestricted Entities (other than Unrestricted Entities the primary assets of which are cash and/or Cash Equivalents); and 

(xix) the payment of cash in lieu of the issuance of fractional shares of Equity Interests upon exercise or conversion of

Syniverse Restricted Payment permitted under clauses (iv), (vi), (viii), (ix), (x), (xi) and (xviii) of this Section 3.17(b), no Default or Event of Default shall have occurred and be continuing or would occur as a consequence
thereof. 
 As of the Issue Date, all of Syniverse’s Subsidiaries will be Restricted Subsidiaries. Syniverse will not permit any
Unrestricted Entity that is a Subsidiary of Syniverse (other than any Subsidiary of the Issuer) to become a Restricted Subsidiary except pursuant to the definition of “Unrestricted Entity.” For purposes of designating any Restricted
Subsidiary of Syniverse (other than any Restricted Subsidiary of the Issuer) as an Unrestricted Entity, all outstanding Investments by Syniverse and its Restricted Subsidiaries (other than the Issuer and its Restricted Subsidiaries) (except to

  
 113 

 
the extent repaid) in the Subsidiary so designated will be deemed to be Syniverse Restricted Payments or Syniverse Permitted Investments in an amount determined as set forth in the last sentence
of the definition of “Investments.” Such designation will only be permitted if a Syniverse Restricted Payment or Syniverse Permitted Investment in such amount would be permitted at such time and if such Subsidiary otherwise meets the
definition of an Unrestricted Entity. 
 For purposes of this Section 3.17, if any Investment or Syniverse Restricted Payment would be
permitted pursuant to one or more provisions of this Section 3.17 and/or one or more of the exceptions contained in the definition of “Syniverse Permitted Investments,” Syniverse may divide and classify such Investment or Syniverse
Restricted Payment in any manner that complies with this Section 3.17 and may later divide and reclassify any such Investment or Syniverse Restricted Payment so long as the Investment or Syniverse Restricted Payment (as so divided and/or
reclassified) would be permitted to be made in reliance on the applicable exception as of the date of such reclassification. 
 SECTION 3.18
Asset Sales Applicable to Syniverse and Its Restricted Subsidiaries (Other than the Issuer and its Restricted Subsidiaries). 
 (a) Syniverse
shall not, and shall not permit any of its Restricted Subsidiaries (other than the Issuer and its Restricted Subsidiaries) to, cause or make a Syniverse Asset Sale, unless: 

(i) Syniverse or any of such Restricted Subsidiaries, as the case may be, receives consideration at the time of such Syniverse
Asset Sale at least equal to the Fair Market Value (as determined in good faith by Syniverse) of the assets sold or otherwise disposed of; and 

(ii) except in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by Syniverse or such
Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents or Replacement Assets; provided, however that the amount of: 

(1) any liabilities (as shown on Syniverse’s or such Restricted Subsidiary’s most recent balance sheet or in the
notes thereto) of Syniverse or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee of any such assets or Equity Interests pursuant to an agreement that releases or
indemnifies Syniverse or such Restricted Subsidiary, as the case may be, from further liability; 
 (2) any notes or other
obligations or other securities or assets received by Syniverse or such Restricted Subsidiary from such transferee that are converted by Syniverse or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the
cash received); and 

  
 114 

 (3) any Syniverse Designated Non-cash Consideration received by Syniverse or any
of its Restricted Subsidiaries in such Syniverse Asset Sale having an aggregate Fair Market Value, taken together with all other Syniverse Designated Non-cash Consideration received pursuant to this clause (3) that is at that time outstanding,
not to exceed the greater of (x) $75.0 million and (y) 2.3% of Syniverse Total Assets, at the time of the receipt of such Syniverse Designated Non-cash Consideration (with the Fair Market Value of each item of Syniverse Designated Non-cash
Consideration being measured at the time received and without giving effect to subsequent changes in value); 
 shall each be deemed to be
Cash Equivalents for the purposes of this clause (ii). 
 (b) Within 365 days after Syniverse’s or any such Restricted Subsidiary’s
receipt of the Net Cash Proceeds of any Syniverse Asset Sale, Syniverse or such Restricted Subsidiary may apply the Net Cash Proceeds from such Syniverse Asset Sale, at its option: 

(i) to permanently reduce Obligations under any Secured Indebtedness of Syniverse or any of its Restricted Subsidiaries
(including, for the avoidance of doubt, the Senior Credit Agreement), any Indebtedness that serves to refund, refinance, replace, redeem, repurchase, retire or defease the Senior Credit Agreement, any Indebtedness Incurred to refund, refinance,
replace, redeem, repurchase, retire or defease such Indebtedness and/or the Existing Notes and, in the case of revolving obligations thereunder, to correspondingly reduce commitments with respect thereto; 

(ii) to permanently reduce Obligations under the Initial Notes (including any Exchange Notes in respect thereto), any
Additional Notes (including any Exchange Notes in respect thereto and any other Notes issued in respect thereof pursuant to Section 2.6, 2.7, 2.10, 3.7, 3.9, 3.18 or 9.4 or Article V) or other Pari Passu Indebtedness of the Issuer or the
Guarantors (provided that if the Issuer shall so reduce such Obligations under such Additional Notes or such other Pari Passu Indebtedness, the Issuer will equally and ratably reduce Obligations under such Initial Notes if such Initial Notes are
then redeemable at par or, if such Initial Notes are not redeemable at par, by making an offer (in accordance with the procedures set forth below for a Syniverse Asset Sale Offer) to all Holders to purchase at a purchase price equal to 100% of the
principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, the pro rata principal amount of such Initial Notes that would otherwise be redeemed) (provided that in the case of any reduction of any revolving
obligations pursuant to this clause (ii), Syniverse or such Restricted Subsidiary shall effect a corresponding reduction of commitments with respect thereto); 

  
 115 

 (iii) to make an Investment in any one or more businesses (provided that if such
investment is in the form of the acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of Syniverse), assets, or property or capital expenditures, in each case used or useful in a Similar
Business; 
 (iv) to make an Investment in any one or more businesses (provided that if such Investment is in the form of the
acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of Syniverse), properties or assets that replace the properties and assets that are the subject of such Syniverse Asset Sale; or 

(v) any combination of the foregoing; 

provided that Syniverse and its Restricted Subsidiaries shall be deemed to have complied with clauses (iii) and (iv) of this Section 3.18(b) if
and to the extent that, within 365 days after the Syniverse Asset Sale that generated the Net Cash Proceeds, Syniverse has entered into and not abandoned or rejected a binding agreement to acquire the assets or Capital Stock of a Similar Business,
make an Investment in Replacement Assets or make a capital expenditure in compliance with clauses (iii) and (iv) of this Section 3.18(b), and that acquisition, purchase or capital expenditure is thereafter completed within 180 days
after the end of such 365-day period. 
 (c) Pending the final application of any such Net Cash Proceeds, Syniverse or such Restricted
Subsidiary of Syniverse may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Cash Proceeds in Cash Equivalents. Any Net Cash Proceeds from any Syniverse Asset Sale that are not applied as
provided and within the time period set forth in Section 3.18(b) will be deemed to constitute “Syniverse Excess Proceeds.” When the aggregate amount of Syniverse Excess Proceeds exceeds $30.0 million, Syniverse shall: 

(i) first, to the extent required under any Secured Indebtedness of Syniverse or any of its Restricted Subsidiaries (including,
for the avoidance of doubt, the Senior Credit Agreement), any Indebtedness that serves to refund, refinance, replace, redeem, repurchase, retire or defease the Senior Credit Agreement, any Indebtedness Incurred to refund, refinance, replace, redeem,
repurchase, retire or defease such Indebtedness and/or the Existing Indenture, use such Syniverse Excess Proceeds to repay Indebtedness, reduce commitments and/or make an offer to repurchase Indebtedness, commitments and/or notes outstanding under
any such Secured Indebtedness, the Senior Credit Agreement, 

  
 116 

 
the Existing Indenture, any Indebtedness that serves to refund, refinance, replace, redeem, repurchase, retire or defease the Senior Credit Agreement and/or any Indebtedness Incurred to refund,
refinance, replace, redeem, repurchase, retire or defease such Indebtedness; and 
 (ii) second, to the extent permitted
under any Secured Indebtedness of Syniverse or any of its Restricted Subsidiaries (including, for the avoidance of doubt, the Senior Credit Agreement), the Existing Indenture, any Indebtedness that serves to refund, refinance, replace, redeem,
repurchase, retire or defease the Senior Credit Agreement and/or the Existing Indenture and any Indebtedness Incurred to refund, refinance, replace, redeem, repurchase, retire or defease such Indebtedness, make an offer (a “Syniverse Asset Sale
Offer”) to all Holders of Initial Notes (including any Exchange Notes in respect thereof) and to all Holders of any Additional Notes (including any Exchange Notes in respect thereof and any other Notes issued in respect thereof pursuant to
Section 2.6, 2.7, 2.10, 3.7, 3.9, 3.18 or 9.4 or Article V) and other Pari Passu Indebtedness of the Issuer and the Guarantors, to purchase the maximum principal amount of such Initial Notes, such Additional Notes and such other Pari Passu
Indebtedness, on a pro rata basis, that may be purchased out of the Syniverse Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to,
but excluding, the date fixed for the closing of such offer (or such lesser price, if any, as may be provided by the terms of such Additional Notes or such Pari Passu Indebtedness, as applicable), in accordance with the procedures set forth in this
Indenture. 
 To the extent required by Section 3.18(c)(ii), Syniverse will commence a Syniverse Asset Sale Offer with respect to
Syniverse Excess Proceeds within ten days after the later of the date of the application of such Syniverse Excess Proceeds pursuant to Section 3.18(c)(i) and the date that such Syniverse Excess Proceeds exceed $30.0 million by sending the
notice required pursuant to the terms of this Indenture, with a copy to the Trustee. To the extent that the aggregate amount of such Initial Notes, such Additional Notes and such other Pari Passu Indebtedness tendered pursuant to a Syniverse Asset
Sale Offer is less than the Syniverse Excess Proceeds, Syniverse may use any remaining Syniverse Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of such Initial Notes, such Additional
Notes and such other Pari Passu Indebtedness surrendered by holders thereof exceeds the amount of Syniverse Excess Proceeds, the Trustee shall select the Notes to be purchased in the manner described below. Upon completion of any such Syniverse
Asset Sale Offer, the amount of Syniverse Excess Proceeds shall be reset at zero. 
 (d) Syniverse shall comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations to the extent such laws or regulations are applicable in connection with the purchase of the Notes pursuant to a 

  
 117 

 
Syniverse Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, Syniverse shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. 

(e) If more Notes are tendered pursuant to a Syniverse Asset Sale Offer than Syniverse is required to purchase, selection of such Notes for
purchase will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed (so long as the Trustee knows of such listing) or if such Notes are not listed, on a pro
rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements, and, in the case of Global Notes, the procedures of the Depositary); provided, that the
selection of Notes for purchase shall not result in a Holder with a principal amount of Notes less than the Minimum Denomination. 
 (f)
Notices of a Syniverse Asset Sale Offer shall be sent at least 30 but not more than 60 days before the Purchase Date to each Holder of the Notes electronically, by first class mail to its registered address or otherwise in accordance with the
procedures of the Depositary. If any Note is to be purchased in part only, any notice of purchase that relates to such Note shall state the portion of the principal amount thereof that has been or is to be purchased. 

A new Note in principal amount equal to the unpurchased portion of any Note purchased in part will be issued in the name of the Holder thereof
upon cancellation of the original Note (or if the Note is a Global Note, an adjustment shall be made to the “Schedule of Increases or Decreases in Global Note” attached thereto). On and after the Purchase Date, unless Syniverse defaults in
payment of the purchase price, interest shall cease to accrue on Notes or portions thereof purchased.

occurred and be continuing; 
 (iii) the Issuer or the SFHC Successor Company, as the case may be, shall have delivered or
caused to be delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture; and 

(iv) if the SFHC Successor Company is other than the Issuer, each Guarantor, unless it is the other party to the transactions

The SFHC Successor Company (if other than the Issuer) will succeed to, and be substituted for, the Issuer under this Indenture and the Notes,
and the Issuer will automatically be released and discharged from its obligations under this Indenture and the Notes. Notwithstanding the foregoing clauses (ii) or (iii), (a) any Restricted Subsidiary may consolidate with, merge into or
sell, assign, transfer, lease, convey or otherwise dispose of all or part of its properties and assets to the Issuer, (b) the Issuer may merge or consolidate with an Affiliate incorporated or organized solely for the purpose of reincorporating
or reorganizing the Issuer in another state of the United States, the District of Columbia or any territory of the United States so long as the amount of Indebtedness of the Issuer and its Restricted Subsidiaries is not increased thereby and
(c) the Issuer may convert into a corporation, partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of the Issuer. 

  
 119

organized or existing under such laws; 
 (ii) the Syniverse Successor Company (if other than Syniverse) expressly assumes
all the obligations of Syniverse under this Indenture and the Notes pursuant to a supplemental indenture;

Syniverse Successor Company or such Restricted Subsidiary at the time of such transaction) no Default or Event of Default shall have occurred and be continuing; 

(iv) immediately after giving pro forma effect to such transaction, as if such transaction had occurred at the beginning of the
applicable four-quarter period, either:

such consolidation, merger or transfer and such supplemental indentures (if any) comply with this Indenture. 
 The Syniverse Successor
Company (if other than Syniverse) will succeed to, and be substituted for, Syniverse under this Indenture and the Notes, and Syniverse will automatically be released and discharged from its obligations under this Indenture and the

of all or substantially all of its properties or assets in one or more related transactions to, any Person unless: 
 (i)
either (a) such Guarantor is the surviving Person or the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have
been made is a corporation, partnership or limited liability company organized or existing under the laws of the United States, any state thereof, the District of Columbia or any territory thereof (such Guarantor or such Person, as the case may be,
being herein called the “Successor Guarantor”) and the Successor Guarantor (if other than such Guarantor) expressly assumes all the obligations of such Guarantor under this Indenture and such Guarantor’s Guarantee pursuant to a
supplemental indenture or (b) such sale or disposition or consolidation or merger is not in violation of Section 3.18 (for purposes of this clause (b), without giving effect to clause (b) of the definition of “Syniverse Asset
Sale”); 
 (ii) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an
obligation of the Successor Guarantor or any of its Restricted Subsidiaries as a result of such transaction as having been Incurred by the Successor Guarantor or such Restricted Subsidiary at the time of such transaction) no Default or Event of
Default shall have occurred and be continuing; and 
 (iii) the Successor Guarantor (if other than such Guarantor) shall have
delivered or caused to be delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture.

Guarantor under this Indenture and such Guarantor’s Guarantee, and such Guarantor shall automatically be released and discharged from its obligations under this Indenture and such Guarantor’s Guarantee. Notwithstanding the foregoing
clauses (ii) or (iii), (1) a Guarantor may merge or consolidate with an Affiliate incorporated or organized solely for the purpose of reincorporating or reorganizing such Guarantor in another state of the United States, the District of
Columbia or any territory of the United States, so long as the amount of Indebtedness of the Guarantor is not increased thereby, (2) a Guarantor may merge or consolidate with another Guarantor or Syniverse and (3) a Guarantor may convert
into a corporation, partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor. 

ARTICLE V 
 Redemption of Notes

 SECTION 5.1 Applicability of Article. Notes of or within any series that are redeemable in whole or in part before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise specified for Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by Section 2.1) in accordance with this Article V. 

SECTION 5.2 Optional Redemption. 

(a) The Notes of any series may be redeemed, in whole at any time, or in part from time to time, subject to the conditions and at the
Redemption Prices set forth in Paragraph 6 of the applicable Notes Supplemental Indenture, which are hereby incorporated by reference and made a part of this Indenture, together with accrued and unpaid interest to, but excluding, the applicable
Redemption Date. 
 (b) In connection with any redemption of Notes (including with the net cash proceeds of an Equity Offering), any such
redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent, including consummation of any related Equity Offering or consummation of a Change of Control. In addition, if such redemption or notice is subject to
satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Issuer in its sole
discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the Redemption Date, or by the Redemption
Date so delayed. 

  
 122 

 SECTION 5.3 Election to Redeem; Notice to Trustee of Optional and Mandatory Redemptions. If the
Issuer elects to redeem Notes pursuant to this Article V, the Issuer shall furnish to the Trustee, at least 2 Business Days for Global Notes and 10 calendar days for Definitive Notes before notice of redemption is required to be sent or caused
to be sent to Holders pursuant to Section 5.5, an Officer’s Certificate setting forth (a) the paragraph or subparagraph of such Note and/or Section of this Indenture pursuant to which the redemption shall occur, (b) the
Redemption Date, (c) the principal amount of the Notes to be redeemed and (d) the Redemption Price, but failure to so notify the Trustee shall not invalidate any notice given in accordance with Section 5.5, and shall not constitute a
Default or Event of Default by the Issuer. The Issuer may also include a request in such Officer’s Certificate that the Trustee sends the notice of redemption in the Issuer’s name and at its expense and setting forth the information to be
stated in such notice as provided in Section 5.5. The Issuer shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 5.4. 

SECTION 5.4 Selection by Trustee of Notes to Be Redeemed. Unless otherwise specified for Notes of any series in the applicable Notes
Supplemental Indenture, as contemplated by Section 2.1, if less than all of the Notes are to be redeemed at any time, the Trustee shall select Notes for redemption in compliance with the requirements of the principal national securities
exchange, if any, on which such Notes are listed (so long as the Trustee knows of such listing), or if such Notes are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such
manner as complies with applicable legal requirements and, in the case of Global Notes, the procedures of the Depositary); provided, that the selection of Notes for redemption shall not result in a Holder of Notes with a principal amount of Notes
less than the Minimum Denomination. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof shall be issued in the name of the Holder thereof upon cancellation of the original Note (or if the Note is a Global Note, an adjustment shall be made to the “Schedule of Increases or Decreases in Global Note”
attached thereto). On and after the applicable Redemption Date, interest and Additional Interest, if any, will cease to accrue on Notes or portions thereof called for redemption so long as the Issuer has deposited with the Paying Agent funds
sufficient to pay the principal of, plus accrued and unpaid interest and Additional Interest, if any, on, the Notes to be redeemed. 
 The
Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Notes shall relate, in the
case of any Note redeemed or to be redeemed only in part, to the portion of the principal amount of such Note which has been or is to be redeemed. 

  
 123 

 SECTION 5.5 Notice of Redemption. Unless otherwise specified for Notes of any series in the
applicable Notes Supplemental Indenture, as contemplated by Section 2.1, the Issuer shall send or cause to be sent to each Holder whose Notes are to be redeemed, electronically, by first class mail to such Holder’s registered address or
otherwise in accordance with the procedures of the Depositary, a notice of redemption not less than 30 nor more than 60 days prior to a date fixed for redemption (a “Redemption Date”); provided, however, that redemption notices may be sent
more than 60 days prior to a Redemption Date if the notice is issued in connection with Article VIII or if the Redemption Date is delayed as provided in Section 5.2(b). At the Issuer’s written request, the Trustee may send notice of
redemption in the Issuer’s name and at the Issuer’s expense; provided that the Issuer shall have delivered to the Trustee at least two Business Days (or such shorter period as agreed to by the Trustee in its sole discretion) before notice
of redemption is required to be sent to Holders pursuant to this Section 5.5, an Officer’s Certificate requesting that the Trustee give such notice and providing a form of such notice. 

All notices of redemption shall be prepared by the Issuer and shall state: 

(a) the Redemption Date, 

(b) the Redemption Price and the amount of accrued and unpaid interest, including Additional Interest, if any, to, but
excluding, the Redemption Date payable as provided in Section 5.7, if any, 
 (c) if less than all outstanding Notes are
to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial
redemption, 
 (d) in case any Note is to be redeemed in part only, the notice which relates to such Note shall state that on
and after the Redemption Date, upon surrender of such Note, the Holder shall receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof remaining unredeemed (or if the Note is a Global Note, that an
adjustment shall be made to the “Schedule of Increases or Decreases in Global Note” attached thereto), 
 (e) that
on the Redemption Date the Redemption Price (and accrued and unpaid interest, including Additional Interest, if any, to, but excluding, the Redemption Date payable as provided in Section 5.7) shall become due and payable upon each such Note, or
the portion thereof, to be redeemed, and, unless the Issuer defaults in making the redemption payment, that interest on Notes called for redemption (or the portion thereof) shall cease to accrue on and after said date, 

  
 124 

 (f) the place or places where such Notes are to be surrendered for payment of the
Redemption Price and accrued and unpaid interest, including Additional Interest, if any, 
 (g) the name and address of the
Paying Agent, 
 (h) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption
Price, 
 (i) the CUSIP number, and that no representation is made as to the accuracy or correctness of the CUSIP number, if
any, listed in such notice or printed on the Notes, and 
 (j) the Section of this Indenture pursuant to which the Notes are
to be redeemed and any conditions to such redemption pursuant to Section 5.2(b). 
 SECTION 5.6 Deposit of Redemption Price. Prior to
10:00 a.m., New York City time, on any Redemption Date, the Issuer shall deposit with the Trustee or a Paying Agent (or, if the Issuer is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.4) an amount of money
sufficient to pay the Redemption Price of, and accrued and unpaid interest, including Additional Interest, if any, on, all the Notes which are to be redeemed on that date. 

SECTION 5.7 Notes Payable on Redemption Date. Notice of redemption having been sent as aforesaid, the Notes so to be redeemed shall, on the
Redemption Date, become due and payable at the Redemption Price therein specified (together with accrued and unpaid interest and Additional Interest, if any, to, but excluding, the Redemption Date), and from and after such date (unless the Issuer
shall default in the payment of the Redemption Price and accrued and unpaid interest and Additional Interest, if any, to, but excluding, the Redemption Date) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in
accordance with said notice, such Note shall be paid by the Issuer at the Redemption Price, together with accrued and unpaid interest, including Additional Interest, if any, to, but excluding, the Redemption Date (subject to the rights of Holders of
record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption Date). 

If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until
paid, bear interest (including Additional Interest, if any) from the Redemption Date at the rate borne by the Notes. 

  
 125 

 If a Redemption Date is on or after a Regular Record Date and on or before the related Interest
Payment Date, the accrued and unpaid interest and Additional Interest, if any, shall be paid to the Person in whose name the Note is registered at the close of business on such Regular Record Date, and no further interest shall be payable to Holders
whose Notes shall be subject to redemption by the Issuer. 
 SECTION 5.8 Notes Redeemed in Part. Any Note which is to be redeemed only in
part (pursuant to the provisions of this Article) shall be surrendered at the office or agency of the Issuer maintained for such purpose pursuant to Section 2.3 and specified in the applicable notice of redemption (with, if the Issuer so
requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuer duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Issuer shall execute, and the Trustee upon
receipt of an Authentication Order shall authenticate and make available for delivery to the Holder of such Note at the expense of the Issuer, a new Note or Notes, of any authorized denomination as requested by such Holder, in an aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered, provided that each such new Note shall be in the Minimum Denomination and integral multiples of $50 in excess thereof (or if the Note is a Global
Note, an adjustment shall be made to the “Schedule of Increases or Decreases in Global Note” attached thereto). 
 SECTION 5.9
Offer to Repurchase. In the event that, pursuant to Section 3.7 or Section 3.18, the Issuer or Syniverse is required to commence an offer to all Holders to purchase the Notes (an “Offer to Repurchase”), it shall follow the
procedures specified below. 
 (a) The Offer to Repurchase shall remain open for a period of at least 20 Business Days following its
commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase
Date”), the Issuer shall apply all SFHC Excess Proceeds or Syniverse shall apply all Syniverse Excess Proceeds, as applicable (the “Offer Amount”), pursuant to Section 3.7 or Section 3.18, as applicable, to the purchase of
Initial Notes (including any Exchange Notes in respect thereof), any Additional Notes (including any Exchange Notes in respect thereof and any other Notes issued in respect thereof pursuant to Section 2.6, 2.7, 2.10, 3.7, 3.9, 3.18 or 9.4 or
Article V) and, in the case of Section 3.18, other Pari Passu Indebtedness, as applicable. Payment for any Notes so purchased shall be made pursuant to Section 3.1. 

(b) If the Purchase Date is on or after a Regular Record Date and on or before the related Interest Payment Date, any accrued and unpaid
interest and Additional Interest, if any, shall be paid to the Person in whose name a Note is registered at the close of business on such Regular Record Date, and no additional interest shall be payable to Holders who tender Notes pursuant to the
Offer to Repurchase. 

  
 126 

 (c) Upon the commencement of an Offer to Repurchase, the Issuer or Syniverse, as applicable,
shall send a notice to the Trustee and each of the Holders, electronically, by first class mail to such Holder’s registered address or otherwise in accordance with the procedures of the Depositary. The notice shall contain all instructions and
materials necessary to enable such Holders to tender Notes pursuant to the Offer to Repurchase. The notice, which shall govern the terms of the Offer to Repurchase, shall state:

applicable, and the length of time the Offer to Repurchase shall remain open; 
 (ii) the Offer Amount, the purchase price
and the Purchase Date; 
 (iii) that any Note not tendered or accepted for payment shall continue to accrue interest;

 (vii) that Holders shall be entitled to
withdraw their election if the Issuer or the applicable Agent, as the case may be, receives, not later than on the expiration of the Offer Period, a telegram, facsimile transmission, letter or electronic transmission in the form of a “pdf”
on letterhead (if applicable) and signed by an authorized signer setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note
purchased; 
 (viii) that, if the aggregate principal amount of Initial Notes (including any Exchange Notes in respect
thereof), any Additional Notes (including any Exchange Notes in respect thereof and any other Notes issued in respect thereof pursuant to Section 2.6, 2.7, 2.10, 3.7, 3.9, 3.18 or 9.4 or Article V) and, in the

  
 127 

 
case of Section 3.18, other Pari Passu Indebtedness, as applicable, surrendered by Holders thereof exceeds the Offer Amount, the Trustee shall select such Initial Notes and any such
Additional Notes, as applicable, to be purchased or prepaid, on a pro rata basis based on the principal amount of such Initial Notes, any such Additional Notes and, in the case of Section 3.18, such other Pari Passu Indebtedness, as applicable,

 ARTICLE VI 

Defaults and Remedies 
 SECTION
6.1 Events of Default. Each of the following is an “Event of Default”: 
 (i) a default in any payment of interest
on any Note when due continued for 30 days; 

  
 128 

 (ii) a default in the payment of principal or premium, if any, of any Note when
due at its Stated Maturity, upon optional redemption, upon required purchase, upon acceleration or otherwise; 
 (iii) the
failure by the Issuer or any of its Restricted Subsidiaries or Syniverse or any of its Restricted Subsidiaries (other than the Issuer and its Restricted Subsidiaries) to comply for 60 days after written notice with any of its other agreements
contained in the Notes or this Indenture; 
 (iv) the failure by the Issuer or any Significant Entity or by Syniverse or any
Significant Subsidiary to pay any Indebtedness (other than Indebtedness owing to Syniverse or a Restricted Subsidiary of Syniverse) within any applicable grace period after final maturity or the acceleration of any such Indebtedness by the holders
thereof because of a default, in each case, if the total amount of such Indebtedness unpaid or accelerated exceeds (i) in the case of the Issuer or any Significant Entity, $25.0 million or its foreign currency equivalent or (ii) in the
case of Syniverse or any Significant Subsidiary, $50.0 million or its foreign currency equivalent; 
 (v) the Issuer or any
Significant Entity or Syniverse or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law: 
 (1)
commences a voluntary case; 
 (2) consents to the entry of an order for relief against it in any voluntary case; 

(3) consents to the appointment of a Custodian of it or for any substantial part of its property; or 

(4) makes a general assignment for the benefit of its creditors; 

or takes any comparable action under any foreign laws relating to insolvency; 

(vi) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(1) is for relief against the Issuer or any Significant Entity or Syniverse or any Significant Subsidiary in an involuntary
case; 

  
 129 

 (2) appoints a Custodian of the Issuer or any Significant Entity or Syniverse or
any Significant Subsidiary or for any substantial part of its property; or 
 (3) orders the winding up or liquidation of the
Issuer or any Significant Entity or Syniverse or any Significant Subsidiary; 
 or any similar relief is granted under any
foreign laws and the order or decree remains unstayed and in effect for 60 days; 
 (vii) failure by the Issuer or any
Significant Entity or by Syniverse or any Significant Subsidiary to pay final and non-appealable judgments aggregating in excess of (i) in the case of the Issuer or any Significant Entity, $25.0 million or (ii) in the case of Syniverse or
any Significant Subsidiary, $50.0 million or its foreign currency equivalent (in each case, net of any amounts which are covered by enforceable insurance policies issued by solvent insurance companies), which judgments are not discharged, waived or
stayed for a period of 60 days and, in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed; or 

(viii) the Guarantee of Syniverse, any Significant Subsidiary or any Significant Entity ceases to be in full force and effect
(except as contemplated by the terms thereof), or Syniverse or any Guarantor that is a Significant Subsidiary or a Significant Entity denies that it has any further liability under its Guarantee or gives notice to such effect, other than by reason
of the termination of this Indenture or the release of any such Guarantee in accordance with this Indenture, and such Default continues for 10 days. 

The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 

However, a default under clause (iii) of this Section 6.1 will not constitute an Event of Default until the Trustee or the Holders
of at least 25% in principal amount of then outstanding Notes (which contain such default, or such other percentage of principal of outstanding Notes containing such default as specified for Notes of any series in the applicable Notes Supplemental
Indenture) notify the Issuer of the default and the Issuer or Syniverse, as applicable, does not cure such default within the time specified in clause (iii) of this Section 6.1 after receipt of such notice. 

SECTION 6.2 Acceleration. If an Event of Default (other than an Event of Default specified in Sections 6.1(v) or (vi) above with respect
to the Issuer or Syniverse) 

  
 130 

 
occurs and is continuing, unless otherwise specified for Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by Section 2.1, the Trustee or the Holders of at
least 25% in principal amount of then outstanding Notes (which contain such default) by written notice to the Issuer (with a copy to the Trustee, if given by the Holders) may declare the principal of, premium, if any, and accrued but unpaid interest
on all such Notes to be due and payable. Upon such a declaration, such principal and interest will be due and payable immediately. If an Event of Default arising from Sections 6.1(v) or (vi) with respect to the Issuer or Syniverse, as
applicable, occurs, unless otherwise specified for Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by Section 2.1, the principal of, premium, if any, and accrued but unpaid interest on all the Notes (which
contain such default) will become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. 

SECTION 6.3 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the
payment of principal of or interest on the Notes (which contain such default) or to enforce the performance of any provision of the Notes, this Indenture (including sums owed to the Trustee and its agents and counsel) and the Guarantees. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes (which contain such default) or does not produce any of
them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No
remedy is exclusive of any other remedy. All available remedies are cumulative. 
 SECTION 6.4 Waiver of Past Defaults. The Holders of a
majority in aggregate principal amount of the then outstanding Notes (which contain such default which has been accelerated) by notice to the Trustee may, on behalf of the Holders of all of the Notes (which contain such default), waive, rescind or
cancel any declaration of an existing or past Default or Event of Default and its consequences under this Indenture if such waiver, rescission or cancellation would not conflict with any judgment or decree, except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the applicable Notes (other than such nonpayment of principal or interest that has become due as a result of such acceleration). Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

In the event of any Event of Default arising from Section 6.1(iv), such Event of Default and all consequences thereof (excluding,
however, any resulting payment default) will be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders of the Notes, if prior to the earlier of (i) a declaration of

  
 131 

 
acceleration pursuant to the preceding paragraph and (ii) 20 days after such Event of Default arose, the Issuer delivers an Officer’s Certificate to the Trustee stating that
(x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (y) the Holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of
Default or (z) the default that is the basis for such Event of Default has been cured. 
 SECTION 6.5 Control by Majority. The Holders
of a majority in principal amount of the then outstanding Notes (which contain the default for which a remedy is being enforced) may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that
would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to security or indemnification satisfactory to it in its sole discretion against all losses, liabilities and expenses
that may be caused by taking or not taking such action. 
 SECTION 6.6 Limitation on Suits. In case an Event of Default occurs and is
continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to
it against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest or Additional Interest, if any, when due, no Holder may pursue any remedy with respect to this Indenture or the
Notes unless: 
 (i) such Holder (which holds Notes containing such default) has previously given the Trustee notice that an
Event of Default is continuing, 
 (ii) Holders of at least 25% of the aggregate principal amount of the then outstanding
Notes (which contain such default, or such other percentage of principal of outstanding Notes containing such default as specified for Notes of any series in the applicable Notes Supplemental Indenture) have requested the Trustee in writing to
pursue the remedy, 
 (iii) such Holders have offered the Trustee security or indemnity reasonably satisfactory to it in
respect of any loss, liability or expense, 
 (iv) the Trustee has not complied with such request within 60 days after the
receipt of the request and the offer of security or indemnity, and 
 (v) the Holders of a majority in principal amount of
the then outstanding Notes (which contain such default) have not given the Trustee a direction inconsistent with such request within such 60-day period. 

  
 132 

 SECTION 6.7 [Reserved]. 

SECTION 6.8 Collection Suit by Trustee. If an Event of Default specified in Section 6.1(i) or (ii) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in
Section 7.6. 
 SECTION 6.9 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Issuer, its Subsidiaries, the Guarantors or their respective creditors or properties and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders (pursuant to the written direction of Holders
of a majority in principal amount of the then outstanding applicable Notes) in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each
Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.6. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan or reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in such proceeding. 

SECTION 6.10 Priorities. The Trustee shall pay out any money or property received by it in the following order: 

First: to the Trustee for amounts due under Section 7.6; 

Second: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without
preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and 

Third: to the Issuer or, to the extent the Trustee receives any amount for any Guarantor, to such Guarantor as a court of
competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this
Section 6.10. At least 15 days before such record date, the Trustee shall mail to each Holder and the Issuer a notice that states the record date, the payment date and amount to be paid. 

  
 133 

 SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in
its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder to enforce the right to receive payment of principal, premium, if any, or interest or Additional Interest, if any, when due or a suit by Holders of more than 10% in
outstanding principal amount of the Notes.

 SECTION 7.1 Duties of
Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this
Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs; provided that if an Event of Default occurs and is continuing,
the Trustee shall not be under any obligation to exercise any of the rights or powers under this Indenture, the Notes and the Guarantees at the request or direction of any of the Holders unless such Holders have offered the Trustee indemnity,
security or prefunding satisfactory to the Trustee in its sole discretion against any loss, liability or expense it may incur. 
 (b) Except
during the continuance of an Event of Default of which a Trust Officer has actual knowledge, the Trustee: 
 (i) undertakes
to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(ii) in the absence of gross negligence or bad faith on its part, may conclusively rely, as to the truth of the statements and
the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee under this Indenture, the Notes and the Guarantees, as applicable. However, in the case of any such certificates or opinions which by any
provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture, the Notes and the Guarantees as the
case may be (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 

  
 134 

 (c) The Trustee shall not be relieved from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct, except that: 
 (i) this Section 7.1(c) does not limit the
effect of Section 7.1(b); 
 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a
Trust Officer or Trust Officers unless it is proved in a final non-appealable decision of a court of competent jurisdiction that the Trustee was negligent in ascertaining the pertinent facts; and

its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or thereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds
or indemnity satisfactory to it against such risk or liability is not reasonably assured to it. 
 (g) Every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.1. 

(h) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders unless such Holders shall have offered to the Trustee security, prefunding or indemnity satisfactory to it against the losses, expenses (including reasonable attorneys’ fees and expenses) and liabilities that might be

 135 

 SECTION 7.2 Rights of Trustee. 

(a) The Trustee may conclusively rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion,
notice, request, direction, consent, order, bond or any other paper or document believed by it to be genuine and to have been signed or presented by the proper Person or Persons. The Trustee need not investigate any fact or matter stated in such
document. 
 (b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or
both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officer’s Certificate or Opinion of Counsel.

 (d) The Trustee shall not be liable for any

non-appealable decision of a court of competent jurisdiction. 
 (e) The Trustee may consult with counsel of its selection, and the advice or
Opinion of Counsel with respect to legal matters relating to this Indenture, the Notes and the Guarantees shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder or
under the Notes and the Guarantees in good faith and in accordance with the advice or opinion of such counsel. 
 (f) The Trustee shall not
be bound to make any investigation into any statement, warranty or representation, or the facts or matters stated in any resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond or other paper or
document made or in connection with this Indenture; moreover, the Trustee shall not be bound to make any investigation into (i) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein,
(ii) the occurrence of any default, or the validity, enforceability, effectiveness or genuineness of this Indenture or any other agreement, instrument or document, or (iii) the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation

shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

  
 136 

 (g) The Trustee shall not be deemed to have knowledge of any Default or Event of Default except
any Default or Event of Default of which a Trust Officer shall have (x) received written notification from the Issuer or a Holder at the Corporate Trust Office of the Trustee and such notice references the Notes and this Indenture or
(y) obtained “actual knowledge.” “Actual knowledge” shall mean the actual fact or statement of knowing by a Trust Officer without independent investigation with respect thereto. 

(h) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever
(including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

(i) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

at such time to take specified actions pursuant to this Indenture. 
 (k) The Trustee shall not have any duty (A) to see to any
recording, filing, or depositing of this Indenture or any agreement referred to herein, or to see to the maintenance of any such recording or filing or depositing or to any rerecording, re-filing or redepositing of any thereof or (B) to see to
any insurance. 
 (l) The permissive rights of the Trustee enumerated in this Indenture shall not be construed as a duty. 

SECTION 7.3 Individual Rights of Trustee. 

(a) Subject to the TIA (if this Indenture is then qualified under the TIA) each of the Trustee in its individual or any other capacity may
become the owner or pledgee of Notes and may otherwise deal with the Issuer, the Guarantors or their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same
with like rights. However, the Trustee must comply with Section 7.9. 
 (b) In addition, the Trustee shall be permitted to engage in
transactions with the Issuer; provided, however, that if the Trustee acquires any conflicting interest the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the SEC for permission
to continue acting as Trustee or (iii) resign. 

  
 137 

 (c) (i) Prior to the qualification of this Indenture under the TIA, to the extent permitted by
applicable law and (ii) following the qualification of this Indenture under the TIA, to the extent permitted by the TIA, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with
respect to Initial Notes and Additional Notes, or a trustee under any other indenture between the Issuer and/or any of its Affiliates and the Trustee. 

SECTION 7.4 Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture,
the Notes or the Guarantees, it shall not be accountable for the Issuer’s use of the Notes or the proceeds from the Notes, and it shall not be responsible for any statement of the Issuer in this Indenture or in any document issued in connection
with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication or for the use or application of any funds received by any Paying Agent other than the Trustee. 

SECTION 7.5 Notice of Defaults. If a Default occurs and is continuing and is actually known to a Trust Officer of the Trustee, the Trustee
shall send to each Holder of Notes notice of the Default within 90 days after it is known to a Trust Officer of the Trustee. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Note, the Trustee may
withhold notice if and so long as it in good faith determines that withholding notice is in the interests of the Holders of the Notes. 

SECTION 7.6 Compensation and Indemnity. The Issuer shall pay to the Trustee from time to time such compensation for their services as the
parties shall agree in writing from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable out-of-pocket
expenses incurred or made by it, including, but not limited to, costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Holders and reasonable costs of counsel,
in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Issuer shall indemnify the Trustee
or any predecessor Trustee in each of its capacities hereunder (including Paying Agent and Registrar), and each of their officers, directors, employees, counsel and agents, against any and all loss, liability or expense (including, but not limited
to, reasonable attorneys’ fees and expenses) incurred by it in connection with the administration of this trust and the performance of their duties hereunder and under the Notes and the Guarantees, including the costs and expenses of enforcing
this Indenture (including this Section 7.6), the Notes and the Guarantees and of defending itself against any claims (whether asserted by any Holder, the Issuer or otherwise). The Trustee shall notify the Issuer promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend such claim and the Trustee may have separate counsel and the Issuer shall pay the reasonable
fees and expenses of such counsel. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee as a result of its own willful misconduct, negligence or bad faith. 

  
 138 

 To secure the Issuer’s payment obligations in this Section 7.6, the Trustee shall have
a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Notes. The right of the Trustee to receive payment of any amounts due under
this Section 7.6 shall not be subordinate to any other liability or indebtedness of the Issuer. 
 The Issuer’s obligations
pursuant to this Section 7.6 and any lien arising hereunder shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.1(v) or (vi) with respect to the Issuer, the expenses are intended to constitute expenses of administration under any Bankruptcy Law. 

Pursuant to Section 10.1, the obligations of the Issuer hereunder are jointly and severally guaranteed by the Guarantors. 

SECTION 7.7 Replacement of Trustee. The Trustee may resign at any time by so notifying the Issuer in writing. The Holders of a majority in
principal amount of the Notes may remove the Trustee by so notifying the Issuer and the Trustee in writing and may appoint a successor Trustee. The Issuer shall remove the Trustee if: 

(i) the Trustee fails to comply with Section 7.9; 

(ii) the Trustee is adjudged bankrupt or insolvent; 

(iii) a receiver or other public officer takes charge of the Trustee or its property; or 

(iv) the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns or is removed by the Issuer or by the Holders of a majority in principal amount of the Notes and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the “retiring Trustee”), the Issuer shall promptly appoint a successor
Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon
the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice

  
 139 

 
of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.6. All
costs reasonably incurred in connection with any resignation or removal hereunder shall be borne by the Issuer. 
 If a successor Trustee
does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee at the expense of the Issuer or the Holders of at least 10% in principal amount of the Notes may petition any court of competent jurisdiction
for the appointment of a successor Trustee. 
 If the Trustee fails to comply with Section 7.9, unless the Trustee’s duty to
resign is stayed, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

Notwithstanding the replacement of the Trustee pursuant to this Section 7.7, the Issuer’s obligations under Section 7.6 shall
continue for the benefit of the retiring Trustee. 
 SECTION 7.8 Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

 In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts
created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have. 

SECTION 7.9 Eligibility; Disqualification. The Trustee shall have a combined capital and surplus of at least $50 million as set forth in its
most recent filed annual report of condition. 
 This Indenture shall always have a Trustee who satisfies the requirements of TIA
§§ 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). 
 SECTION 7.10 Limitation on Duty of Trustee.
The Trustee shall not have any duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture, the Notes and the Guarantees by the Issuer, the Guarantors or any other Person. 

  
 140 

 SECTION 7.11 Preferential Collection of Claims Against the Issuer. Following the qualification of
this Indenture under the TIA, (i) the Trustee shall be subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b), and (ii) a Trustee who has resigned or been removed shall be subject to TIA
§ 311(a) to the extent indicated therein. 
 SECTION 7.12 Reports by Trustee to Holders of the Notes. Following the qualification
of this Indenture under the TIA, within 60 days after each January 1, the Trustee shall send to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA
§ 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA §
313(c). 
 A copy of each report at the time of its mailing to the Holders of the Notes shall be mailed to the Issuer and, following the
qualification of this Indenture under the TIA, filed with the SEC and each stock exchange on which any Notes are listed in accordance with TIA § 313(d). The Issuer shall promptly notify the Trustee in writing when any Notes are listed on any
stock exchange and of any delisting thereof, but failure to so notify the Trustee shall not constitute a Default or Event of Default by the Issuer. 

ARTICLE VIII

to the payment thereof at maturity or redemption, as the case may be; 

  
 141 

 (b) the Issuer and/or the Guarantors have paid all other sums payable under this
Indenture; and 
 (c) the Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel stating
that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with. 

The Notes of any applicable series shall be discharged and shall cease to be of further effect (except as to surviving rights of registration
of transfer or exchange of Notes of such series, as expressly provided for in this Indenture) when: 
 (a) either
(i) all the Notes of such series theretofore authenticated and delivered (other than such Notes which have been replaced or paid pursuant to Section 2.7 and such Notes for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust) have been delivered to the Trustee for cancellation or (ii) all of the Notes of such series not previously delivered to the Trustee

deposited or caused to be deposited with the Trustee money or U.S. Government Obligations in an amount sufficient to pay and discharge the entire Indebtedness on the Notes of such series not theretofore delivered to the Trustee for cancellation, for
principal of, premium, if any, and interest on such Notes to the date of deposit together with irrevocable instructions from the Issuer directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

 (c) the Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel

Subject to the last paragraph of this Section 8.1 and Section 8.2, the Issuer at any time may terminate (i) all of its
obligations under the Notes and this Indenture (with respect to such Notes) and cure any then-existing Events of Default (“legal defeasance option”) or (ii) its obligations under Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10,

  
 142 

 
3.11, 3.13, 3.14, 3.17 and 3.18 and the operation of Section 4.1 (other than Section 4.1(a)(i)) and Section 4.2 (other than Section 4.2(a)(i) and (ii)) and Sections 6.1(iii)

the obligations of each Guarantor under its Guarantee of such Notes shall be terminated simultaneously with the termination of such obligations. 

If the Issuer exercises its legal defeasance option, payment of the Notes so defeased may not be accelerated because of an Event of Default
with respect thereto. If the Issuer exercises its covenant defeasance option, payment of the Notes so defeased may not be accelerated because of an Event of Default specified in Section 6.1(iii) (with respect to any Default by the Issuer or any
of its Restricted Subsidiaries or Syniverse or any of its Restricted Subsidiaries with any of its obligations under Article III other than Sections 3.1, 3.12, and 3.16, 6.1(iv), 6.1(v) (with respect to Significant Entities of the Issuer and
Significant Subsidiaries of Syniverse only), 6.1(vi) (with respect to Significant Entities of the Issuer and Significant Subsidiaries of Syniverse only), 6.1(vii) (with respect to Significant Entities of the Issuer and Significant Subsidiaries of
Syniverse only) or 6.1(viii). 
 Upon satisfaction of the conditions set forth herein and upon request of the Issuer, the Trustee shall
acknowledge in writing the discharge of those obligations that the Issuer terminates. 
 Notwithstanding the provisions of this
Section 8.1 above, the Issuer’s obligations in Sections 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 7.6, 7.7 and in this Article VIII shall survive until the Notes have been paid in full. Thereafter, the Issuer’s obligations in Sections 7.6, 8.5
and 8.6 shall survive such satisfaction and discharge. 
 SECTION 8.2 Conditions to Defeasance. 

(a) The Issuer may exercise its legal defeasance option or its covenant defeasance option only if: 

(i) the Issuer irrevocably deposits in trust with the Trustee money or U.S. Government Obligations sufficient, without
reinvestment (as determined in good faith by the Issuer), for the payment of principal, premium (if any) and interest on the applicable issue of Notes to redemption or maturity, as the case may be; 

  
 143 

 (ii) [Reserved]; 

(iii) 91 days pass after the deposit is made and during the 91-day period no Default specified in Section 6.1(v) or
(vi) with respect to the Issuer or Syniverse occurs which is continuing at the end of the period; 
 (iv) the deposit
does not constitute a default under any other agreement binding on the Issuer; 
 (v) the Issuer delivers to the Trustee an
Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment advisor under the Investment Advisors Act of 1940; 

(vi) in the case of the legal defeasance option, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating
that (1) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling, or (2) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the
effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal
income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; 

(vii) in the case of the covenant defeasance option, the Issuer shall have delivered to the Trustee an Opinion of Counsel to
the effect that the Holders of the Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amount and in the same manner and at
the same times as would have been the case if such deposit and defeasance had not occurred; and 
 (viii) the Issuer delivers
to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Notes to be so defeased and discharged as contemplated by this Article VIII have been complied
with. 
 Before or after a deposit, the Issuer may make arrangements satisfactory to the Trustee for the redemption of such Notes at a
future date in accordance with Article V. 
 Notwithstanding the foregoing, the Opinion of Counsel required by the clause (vi) above
need not be delivered if all Notes not theretofore delivered to the Trustee for cancellation (x) have become due and payable, (y) will become due and payable at their Stated Maturity within one year or (z) have been called for
redemption within one year. 

  
 144 

 SECTION 8.3 Application of Trust Money. The Trustee shall hold in trust money or U.S. Government

 SECTION 8.4 Repayment to Issuer. Anything herein to the contrary notwithstanding, the Trustee shall deliver or pay to the
Issuer from time to time upon Company Order any money or U.S. Government Obligations held by it as provided in this Article VIII which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect legal defeasance or covenant defeasance, as applicable; provided that the Trustee shall not be required to
liquidate any U.S. Government Obligations in order to comply with the provisions of this Section 8.4. 
 Subject to any applicable
abandoned property law, the Trustee and the Paying Agent shall pay to the Issuer any money held by them for the payment of principal of, or premium, if any, or interest or Additional Interest, if any, on the Notes that remains unclaimed for two
years, and, thereafter, Holders entitled to the money must look to the Issuer for payment as general creditors. 
 SECTION 8.5 Indemnity for
U.S. Government Obligations. The Issuer shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S.
Government Obligations. 
 SECTION 8.6 Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government
Obligations in accordance with this Article VIII by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the
Issuer and each Guarantor under this Indenture, the Notes and the Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to apply all
such money or U.S. Government Obligations in accordance with this Article VIII; provided, however, that, if the Issuer or any of the Guarantors has made any payment of interest on or principal of any Notes because of the reinstatement of its
obligations, the Issuer or any Guarantor, as the case may be, shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

 ARTICLE IX 

Amendments 
 SECTION 9.1 Without
Consent of Holders. Notwithstanding Section 9.2 hereof, this Indenture, the Notes and Guarantees may be amended or supplemented by the Issuer, any Guarantor (with respect to its Guarantee of the Notes) and the Trustee without notice to or
consent of any Holder: 
 (i) to cure any ambiguity, omission, mistake, defect or inconsistency, 

(ii) to conform the text of this Indenture (including any supplemental indenture or other instrument pursuant to which the
Initial Notes and/or Additional Notes are issued), the Guarantees or the Notes (including any Additional Notes) to the “Description of New Notes” in the Offering Memorandum or, with respect to any Additional Notes and any supplemental
indenture or other instrument pursuant to which such Additional Notes are issued, to the “Description of Notes” relating to the issuance of such Additional Notes solely to the extent that such “Description of Notes” provides for
terms that differ from the terms of the Initial Notes, 
 (iii) to provide for the assumption by a successor corporation,
partnership or limited liability company of the obligations of the Issuer, Syniverse or any Guarantor under this Indenture and the Notes or Guarantee, as the case may be, 

(iv) to provide for uncertificated Notes in addition to or in place of certificated Notes; provided that the uncertificated
Notes are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code, 

(v) to add or release Guarantees in accordance with the terms of this Indenture with respect to the Notes, 

(vi) to secure the Notes,

the Issuer,

 (ix) to comply with any requirement of the SEC in connection with any qualification of this Indenture under the TIA, 

  
 146 

 (x) to make certain changes to this Indenture to provide for the issuance of
Additional Notes to the extent permitted by Section 3.3 as in effect prior to such amendment, or 
 (xi) to evidence and
provide for the acceptance of appointment by a successor Trustee; provided that the successor Trustee is otherwise qualified and eligible to act as such under the terms of this Indenture. 

SECTION 9.2 With Consent of Holders. 

(a) This Indenture, the Notes and the Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in
aggregate principal amount of the Notes (including Additional Notes, if any) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes)
and any existing or past default or compliance with any provisions of such documents may be waived with the consent of the Holders of a majority in principal amount of the Notes (including Additional Notes, if any) then outstanding voting as a
single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes); provided that (x) if any such amendment or waiver will only affect one series of Notes (or less than
all series of Notes) then outstanding under this Indenture, then only the consent of the Holders of a majority in principal amount of the Notes of such series then outstanding (including, in each case, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes) shall be required and (y) if any such amendment or waiver by its terms will affect a series of Notes in a manner different and materially adverse relative to the manner such amendment or waiver
affects other series of Notes, then the consent of the Holders of a majority in principal amount of the Notes of such series then outstanding (including, in each case, consents obtained in connection with a purchase of, or tender offer or exchange
offer for Notes) shall be required. However, without the consent of each Holder of an outstanding Note affected, no amendment may (with respect to any Notes held by a non-consenting Holder): 

(i) reduce the percentage of the aggregate principal amount of Notes whose Holders must consent to an amendment; 

(ii) reduce the rate of or extend the time for payment of interest on any Note; 

(iii) reduce the principal of or change the Stated Maturity of any Note; 

(iv) reduce the premium payable upon the redemption of any Note or change the time at which any Note may be redeemed pursuant
to Section 5.2; 

  
 147 

 (v) make any Note payable in money other than that stated in such Note; 

(vi) modify the contractual right of any Holder to receive payment of principal of, premium, if any, and interest on such
Holder’s Notes on or after the due dates therefor, or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes on or after such respective due dates; 

(vii) make any change in the amendment provisions that require each Holder’s consent or in the waiver provisions; 

(viii) make the Notes or any Guarantee subordinated in right of payment to any other obligations; or 

(ix) modify the Guarantees in any manner adverse to the Holders. 

(b) It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent approves the substance thereof. 
 (c) After an amendment under this Section 9.2
becomes effective, the Issuer shall (or shall cause the Trustee, at the expense of and at the written request of the Issuer, to) mail to the Holders of Notes affected thereby a notice briefly describing such amendment. The failure of the Issuer to
mail such notice, or any defect therein, shall not in any way impair or affect the validity of an amendment under this Section 9.2. 

SECTION 9.3 Effect of Consents and Waivers. A consent to an amendment or a waiver by a Holder of a Note shall bind the Holder and every
subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note. After an amendment or waiver becomes effective, it shall bind
every Holder unless it makes a change described in clauses (i) through (ix) of Section 9.2(a), in which case the amendment or waiver or other action shall bind each Holder who has consented to it and every subsequent Holder that
evidences the same debt as the consenting Holder’s Notes. An amendment or waiver made pursuant to Section 9.2 shall become effective upon receipt by the Trustee of the requisite number of written consents. 

The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or
take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their
duly designated proxies), and only those Persons, shall be entitled to give such consent or to take any such action, whether or not such Persons continue to be Holders after such record date. 

  
 148 

 SECTION 9.4 Notation on or Exchange of Notes. If an amendment changes the terms of a Note, the
Trustee may require the Holder of such Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines,
the Issuer in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment. 

SECTION 9.5 Trustee To Sign Amendments. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article IX if
the amendment, supplement or waiver does not, in the sole determination of the Trustee, adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing any amendment,
supplement or waiver pursuant to this Article IX, the Trustee shall be entitled to receive, and (subject to Sections 7.1 and 7.2) shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel stating that such
amendment, supplement or waiver is authorized or permitted by or complies with this Indenture, that all conditions precedent to such amendment required by this Indenture have been complied with and with respect to such Opinion of Counsel that such
amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer, enforceable against the Issuer in accordance with its terms, subject to customary exceptions. Notwithstanding the foregoing, no Opinion of Counsel will be
required for the Trustee to execute any Guarantor Supplemental Indenture. For the avoidance of doubt, no Officer’s Certificate or Opinion of Counsel shall be required for the execution on the Issue Date of any Notes Supplemental Indenture or
supplemental indenture pursuant to Section 4.1 or Section 4.2. 
 ARTICLE X 

Guarantees 
 SECTION 10.1
Guarantees. 
 (a) Subject to the provisions of this Article X, each Guarantor hereby jointly and severally, irrevocably, fully and
unconditionally guarantees, as guarantor and not as a surety, with each other Guarantor, to each Holder of the Notes, to the extent lawful, and the Trustee the full and punctual payment when due, whether at Stated Maturity, by acceleration, by
redemption or otherwise, of the principal of, premium, if any, and interest and Additional Interest, if any, on the Notes and all other Obligations of the Issuer under this Indenture and the Notes (including, without limitation, interest and
Additional Interest, if any, accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Issuer or any Guarantor whether or not a claim for post-filing or
post-petition interest is allowed in such proceeding and the obligations under Section 7.6) (all the foregoing being hereinafter collectively called the “Guarantor Obligations”). Each Guarantor

  
 149 

 
agrees (to the extent lawful) that the Guarantor Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it shall remain bound under this
Article X notwithstanding any extension or renewal of any Guarantor Obligation. 
 (b) Each Guarantor waives (to the extent lawful)
presentation to, demand of, payment from and protest to the Issuer of any of the Guarantor Obligations and also waives (to the extent lawful) notice of protest for nonpayment. Each Guarantor waives (to the extent lawful) notice of any default under
the Notes or the Guarantor Obligations. 
 (c) Each Guarantor further agrees that its Guarantee herein constitutes a Guarantee of payment
when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Guarantor Obligations. 

(d) Except as set forth in Section 10.2 and Article VIII, the obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason (other than payment of the Guarantor Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not (to the extent lawful) be subject
to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guarantor Obligations or otherwise. Without limiting the generality of the foregoing, the obligations
of each Guarantor herein shall not (to the extent lawful) be discharged or impaired or otherwise affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Issuer or any other person
under this Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any
other agreement; (d) the release of any security held by any Holder for the Guarantor Obligations or any of them; (e) the failure of any Holder to exercise any right or remedy against any other Guarantor; (f) any change in the
ownership of the Issuer; (g) any default, failure or delay, willful or otherwise, in the performance of the Guarantor Obligations; or (h) any other act or thing or omission or delay to do any other act or thing which may or might in any
manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity. 

(e) Each Guarantor agrees that its Guarantee herein shall remain in full force and effect until payment in full of all the Guarantor
Obligations or such Guarantor is released from its Guarantee in compliance with Section 4.2, Section 10.2 and Article VIII, as applicable. Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium, if any, or interest on any of the Guarantor Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or
reorganization of the Issuer or otherwise. 

  
 150 

 (f) In furtherance of the foregoing and not in limitation of any other right which any Holder has
at law or in equity against any Guarantor by virtue hereof, upon the failure of the Issuer to pay any of the Guarantor Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each
Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Trustee or the Trustee on behalf of the Holders an amount equal to the sum of (i) the unpaid amount of
such Guarantor Obligations then due and owing and (ii) accrued and unpaid interest on such Guarantor Obligations then due and owing (but only to the extent not prohibited by law) (including interest accruing after the filing of any petition in
bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the Issuer or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding). 

(g) Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity
of the Guarantor Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the
Guarantor Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guarantor Obligations, such Guarantor Obligations (whether or not due and payable) shall forthwith become due and payable by the
Guarantor for the purposes of this Guarantee. 
 (h) Each Guarantor also agrees to pay any and all reasonable costs and expenses (including
reasonable attorneys’ fees) incurred by the Trustee or the Holders in enforcing any rights under this Section 10.1. 
 (i) Neither
the Issuer nor the Guarantors shall be required to make a notation on the Notes to reflect any Guarantee or any release, termination or discharge thereof and any such notation shall not be a condition to the validity of any Guarantee. 

SECTION 10.2 Limitation on Liability; Termination, Release and Discharge. 

(a) Any term or provision of this Indenture to the contrary notwithstanding, the obligations of each Guarantor hereunder shall be limited to
the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of
such other Guarantor under its Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal
or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally. 

  
 151 

 (b) A Guarantee of a Guarantor shall be automatically and unconditionally released and
discharged, and each Guarantor and its obligations under the Guarantee and this Indenture shall be released and discharged, upon: 

(1) the sale, exchange, disposition or other transfer (including through merger or consolidation) of (x) the Capital Stock
of the applicable Guarantor, after which the applicable Guarantor is no longer a Restricted Subsidiary of Syniverse, or (y) all or substantially all the assets of the applicable Guarantor if such sale, exchange, disposition or other transfer is
made in compliance with this Indenture, 
 (2) the Issuer or Syniverse, as applicable, designating such Guarantor to be an
Unrestricted Entity in accordance with the provisions set forth in Section 3.4, 3.14 and/or 3.17. as applicable, and the definition of “Unrestricted Entity,” 

(3) in the case of any Restricted Subsidiary of Syniverse that after the Issue Date is required to guarantee the Notes pursuant
to Section 3.11, the release or discharge of the guarantee by such Restricted Subsidiary of Indebtedness of Syniverse or any Restricted Subsidiary of Syniverse or such Restricted Subsidiary or the repayment of the Indebtedness or Disqualified
Stock, in each case, which resulted in the obligation to guarantee the Notes, except if a release or discharge is by or as a result of payment under such other guarantee, 

(4) the Issuer’s exercise of its legal defeasance option or covenant defeasance option as described under Article VIII or
if the Issuer’s obligations under this Indenture are discharged in accordance with the terms of this Indenture, or 

(5) upon the release or discharge of the guarantee by such Guarantor of the obligations under the Senior Credit Agreement,
except a discharge or release by or as a result of payment under such guarantee. 
 A Guarantee also shall be automatically released upon
the applicable Guarantor ceasing to be a Subsidiary of Syniverse as a result of any foreclosure of any pledge or security interest securing the Senior Credit Agreement or other exercise of remedies in respect thereof. 

(c) The Issuer shall have the right, upon 10 days’ notice to the Trustee (or such shorter period as agreed to by the Trustee in its sole
discretion), to cause any Guarantor that after the Issue Date has guaranteed the Notes pursuant to clause (b) of Section 3.11 and that has not guaranteed any Indebtedness under the Senior Credit Agreement or the Existing Indenture to be
unconditionally released from all obligations under its Guarantee, and such Guarantee shall thereupon terminate and be discharged and of no further force or effect. 

  
 152 

 (d) If any Guarantor is released from its Guarantee, any of its Subsidiaries that are Guarantors
will be released from their Guarantees, if any. 
 (e) If the Issuer requests, at its option, confirmation from the Trustee of a release
pursuant to Section 10.2(b), the Issuer shall deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in this Indenture relating to such transaction have been
complied with. 
 SECTION 10.3 Right of Contribution. Each Guarantor hereby agrees that to the extent that any such Guarantor shall have
paid more than its proportionate share of any payment made on the obligations under its Guarantee, such Guarantor shall be entitled to seek and receive contribution from and against the Issuer or any other Guarantor who has not paid its
proportionate share of such payment. The provisions of this Section 10.3 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders, and each Guarantor shall remain liable to the Trustee and the
Holders for the full amount guaranteed by such Guarantor hereunder. 
 SECTION 10.4 No Subrogation. Notwithstanding any payment or payments
made by each Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Issuer or any other Guarantor or any collateral security or guarantee or right of offset held by the
Trustee or any Holder for the payment of the Guarantor Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Issuer or any other Guarantor in respect of payments made by such Guarantor hereunder,
until all amounts owing to the Trustee and the Holders by the Issuer on account of the Guarantor Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Guarantor
Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to
the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Guarantor Obligations.
