interests in the Restricted Global Notes. Upon consummation of any exchange of Initial Notes for Exchange Additional Notes by the Issuer in accordance with Section 2.06(f) hereof, the requirements of this Section 2.06(b)(2) shall be deemed
to have been satisfied upon receipt by the Registrar of the instructions contained in a letter of direction delivered by the Holder of such beneficial interests in the Restricted Global Notes. Upon satisfaction of all of the requirements for

Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not
outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be
deemed to be outstanding for purposes of Section 3.01(a) hereof. 
 If a Note is replaced pursuant to
Section 2.07 hereof, it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note
and replacement thereof pursuant to Section 2.07. If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 

If the Paying Agent (other than the Issuer, the Company or a Subsidiary of the Company) holds, on a redemption date or
maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.”

unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the
failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid
principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.” 
 (u) The Indenture shall be
amended to restate in its entirety Section 3.07 as follows:

commencement and not more than thirty (30) Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five (5) Business Days after the termination of the
Offer Period (the “Purchase Date”), the Issuer will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other Parity Lien Debt (on a pro rata basis based on the principal amount
of Notes and such other Parity Lien Debt surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. 

(b) If the Purchase Date is on or after an interest record date and on or before the related interest payment date,
accrued and unpaid interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

Purchase Date; 
 (7) that Holders will be entitled to withdraw their election if the Issuer, the Depositary or
the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for
purchase, the serial number of such Note if held in definitive form, and a statement that such Holder is withdrawing his election to have such Note purchased; 
 (8) that, if the aggregate principal amount of Notes and other Parity Lien Debt surrendered by holders thereof exceeds the Offer Amount, the Company will select the Notes and other Parity Lien Debt to be
purchased on a pro rata basis based on the principal amount of Notes and such other Parity Lien Debt surrendered; and 
 (9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

 (d) On or before the Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata
basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee
the Notes properly accepted together with an Officers’ Certificate of the Issuer stating that such Notes or portions thereof were accepted for payment by the

Issuer in accordance with the terms of this Section 3.08. The Issuer, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five
(5) Business Days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuer for purchase. Upon surrender of a Note that is purchased

Note, without service charge, a new Global Note in denomination equal to and in exchange for the unpurchased portion of the principal of the Global Note so surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to

Discussion and Analysis of Financial Condition and Results of Operations,” (B) audited financial statements prepared in accordance with GAAP, and (C) a presentation of Consolidated EBITDA of the Company and its Restricted Subsidiaries

been required to be contained in a Current Report on Form 8-K under the Exchange Act if the Company had been a reporting company under the Exchange Act; provided, however, that no such current report will be required to be furnished if the
Company determines in its good faith judgment that such event is not material to Holders or the business, assets, operations, or financial position of the Company and its Restricted Subsidiaries, taken as a whole. 

Notwithstanding the foregoing, such reports (A) will not be required to comply with Section 302 or
Section 404 of the Sarbanes-Oxley Act of 2002, or related Items 307 and 308 of Regulation S-K promulgated by the SEC, or Item 10(e) of Regulation S-K (with respect to any non-GAAP financial measures contained therein) and (B) will not
be required to contain the separate financial information for Guarantors or Subsidiaries whose securities are pledged to secure the Notes contemplated by Rule 3-10 or Rule 3-16 of Regulation S-X promulgated by the SEC. The availability of any of the

Section 6.01(d), (1) the Company will be deemed not to have failed to comply with any of its obligations under paragraph (a)(1) of this Section 4.03 until fifteen (15) days after the date any financial statements or reports
thereunder are due, and (2) the Company will be deemed not to have failed to comply with any of its obligations under paragraph (a)(2) of this Section 4.03 until five (5) days after the date any financial statements or reports
thereunder are due.

informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of
its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).”

Value as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary after the date of this Indenture; plus 
 (v) 50% of any dividends, distributions, interest payments, return of capital, repayments of Investments or other assets received by the Issuer or any Guarantor after the date of this Indenture from an

(b) The provisions of Section 4.07(a) hereof will not prohibit: 

(1) the payment of any dividend or the consummation of any irrevocable redemption within sixty (60) days after the

purchase a Change of Control Offer (as defined in Section 4.15 hereof) has been made in accordance with the terms hereof and the Issuer has purchased all Notes validly tendered (and not validly withdrawn) for payment in connection with such
Change of Control Offer;

 41 

 (bb) The Indenture shall be amended to restate in its entirety Section 4.08 as
follows: 
 “Section 4.08 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

 (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly,
create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Equity Interests to the Company or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by,
its profits, or pay any indebtedness owed to the Company or any of its Restricted Subsidiaries; 
 (2) make
loans or advances to the Company or any of its Restricted Subsidiaries; or 
 (3) sell, lease or transfer any of
its properties or assets to the Company or any of its Restricted Subsidiaries (provided that dividend or liquidation priority between classes of Equity Interests, or subordination of any obligation (including the application of any remedy bars
thereto) to any other obligation, will not be deemed to constitute such an encumbrance or restriction). 
 (b)
The restrictions in Section 4.08(a) hereof will not apply to encumbrances or restrictions existing under or by reason of: 
 (1) agreements governing Existing Indebtedness as in effect on the date of this Indenture and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings
of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other
payment restrictions than those contained in those agreements on the date of this Indenture (as determined in good faith by the Company); 
 (2) this Indenture, the Notes, the Note Guarantees, the Secured Debt Documents and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of any of
the foregoing; 
 (3) (A) agreements governing other Indebtedness permitted to be incurred under
Section 4.09(b)(15) hereof and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that in the case of this sub-clause (A), the restrictions therein
would not (i) impair, in the Issuer’s good faith reasonable judgment, the ability of the Issuer and the Guarantors to satisfy the Obligations under the Notes, or (ii) otherwise prohibit the Subsidiaries from paying dividends or making
distributions, loans or advances at any time in an amount, together with other 

  
 42 

 
amounts available, sufficient to make payments on the Notes due at such time, and (B) agreements governing other Indebtedness permitted to be incurred under Section 4.09(b) other than
clause (15) thereof, and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that in the case of this sub-clause (B), the restrictions therein are not

(4) applicable law, rule, regulation or order; 

(5) any agreement governing or relating to Indebtedness or Equity Interests of Persons acquired by the Company or any of
its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Equity Interests were incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not
applicable to any Persons, or the properties or assets of any Persons, other than the Persons, or the property or assets of the Persons, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of
this Indenture to be incurred, and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals,
supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of such acquisition (as
determined in good faith by the Company); 
 (6) non-assignment provisions in contracts, leases, subleases,
licenses and sublicenses entered into in the ordinary course of business; 
 (7) mortgage financings and
purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose restrictions on the property mortgaged, purchased or leased of the nature described in clause (3) of the preceding
paragraph;

entered into for the sale or disposition of all or substantially all of the Equity Interests or assets of such Restricted Subsidiary pending the closing of such sale or disposition; 

(9) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such
Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced (as determined in good faith by the Company); 

  
 43 

 (10) Liens permitted to be incurred under the provisions of
Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens; 

(11) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale
agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment), which limitation is applicable only to the assets that are the subject of such
agreements; 
 (12) restrictions on cash or other deposits or net worth imposed by customers under contracts
entered into by the Company or any Restricted Subsidiary; 
 (13) encumbrances and restrictions contained in the
terms of any Indebtedness or any agreement pursuant to which such Indebtedness was issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in such Indebtedness
or agreement and such encumbrance or restriction is not materially more disadvantageous to the holders of the Notes than is customary in comparable financings (as determined in good faith by the Company) and the Company determines that any such
encumbrance or restriction will not materially affect the Issuer’s ability to make principal or interest payments on the Notes; and 
 (14) restrictions on the sale, lease or transfer of property or assets arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the
aggregate, detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary.” 
 (cc) The Indenture shall be amended to restate in its entirety Section 4.09 as follows: 
 “Section 4.09 Incurrence of Indebtedness and Issuance of Disqualified Stock. 
 (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company shall not and shall not permit any of its Restricted Subsidiaries to issue any Disqualified Stock;
provided, however, that the Company and any of its Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, if the Company’s Consolidated Leverage Ratio at the time of incurrence of such
Indebtedness or the issuance of such Disqualified Stock, as the case may be, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom as if the same had occurred at the end of the most
recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been no greater than 3.25 to 1. 

  
 44 

 (b) The provisions of Section 4.09(a) hereof will not prohibit the
incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 

(1) (A) the incurrence by the Issuer or any Guarantor of Priority Lien Debt in an aggregate principal amount at any
time outstanding not to exceed the Priority Lien Cap and (B) the incurrence by the Issuer or any Guarantor of Junior Lien Debt in an aggregate principal amount at any time outstanding not to exceed the Junior Lien Cap;

transactions described in the Offering Circular and (B) Exchange Additional Notes issued under this Indenture following the date of the Second Supplemental Indenture) in an aggregate amount incurred pursuant to this clause (3) not to
exceed the Parity Lien Cap; 
 (4) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness represented by Capital Lease Obligations, mortgage financings, lease financings or purchase money obligations, in each case, incurred for the purpose of financing (whether or not incurred at the time of such purchase, design,
construction, installation, integration or improvement) all or any part of the purchase price or cost of design, construction, installation, integration or improvement of property, plant or equipment used in the business of the Company or any of its
Restricted Subsidiaries, or ownership rights with respect to indefeasible rights of use or minimum investment units (or similar ownership units) in domestic or transnational fiber optic cable or other transmission facilities, and, in each case,
including acquisitions by way of acquisitions of the Equity Interests of a Person that becomes a Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace,
defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed $30.0 million at any time outstanding; 
 (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace,

 45 

 (6) the incurrence by the Company or any of its Restricted Subsidiaries of
intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:

full in cash of all Obligations then due (and not merely outstanding under) with respect to the Notes, in the case of the Issuer, or the Note Guarantee, in the case of a Guarantor; and 

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a
Person other than the Company or a Restricted Subsidiary of the Company, and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company shall be deemed, in each
case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 

(7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted
Subsidiaries of shares of Disqualified Stock; provided, however, that: 
 (A) any subsequent issuance or
transfer of Equity Interests that results in any such Disqualified Stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and 

(B) any sale or other transfer of any such Disqualified Stock to a Person that is not either the Company or a Restricted
Subsidiary of the Company will be deemed, in each case, to constitute an issuance of such Disqualified Stock by such Restricted Subsidiary that was not permitted by this clause (7); 

(8) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of
business or incurred to hedge any interest rate risk on any fixed or floating rate Indebtedness that was permitted to be incurred under the first paragraph of this covenant or any clause under the definition of “Permitted Debt”;

 (9) (A) the Guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or
a Restricted Subsidiary of the Company to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this covenant; provided that if the Indebtedness being Guaranteed is subordinated to or pari
passu with the Notes, then the Guarantee must be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed; and (B) the Guarantee by Restricted Subsidiaries that are not Guarantors of Indebtedness
of Restricted Subsidiaries that are not Guarantors to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this covenant; 

  
 46 

 (10) the incurrence by the Company or any of the Restricted Subsidiaries of
Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, accommodation guarantees for the benefit of trade creditors, completion or performance guarantees, letters of credit, completion or
performance bonds and surety, appeal or judgment bonds or other similar obligations incurred in the ordinary course of business; 
 (11) the incurrence by the Company or any of the Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument

 (12) Indebtedness arising from agreements of the Company or a Restricted Subsidiary providing for indemnification, guarantees, earnouts, purchase price adjustments or similar obligations, in each case,

purpose of financing such acquisition;

Company or any Restricted Subsidiary owing to insurance companies or insurance premium financings, in each case, in the ordinary course of business; 
 (14) (A) Indebtedness of any Persons existing at the time such Persons become Subsidiary Guarantors or Restricted Subsidiaries or are merged with or into or consolidated with the Issuer or any Guarantor
or Restricted Subsidiary, or assumed in connection with an acquisition of property (including Equity Interests) by the Issuer or any Guarantor or Restricted Subsidiary and (B) other Indebtedness incurred in connection with an Asset Acquisition
by the Issuer or any Guarantor or Restricted Subsidiary, provided that such Indebtedness was in existence prior to the contemplation of such Persons becoming Subsidiary Guarantors or Restricted Subsidiaries or such merger or consolidation or
such acquisition of property or Asset Acquisition, provided further that the ratio of the aggregate principal amount of such Indebtedness incurred with respect to any such transaction to Consolidated EBITDA (for the most recent four-quarter
period for which financial information is available) attributable to the Person or property so acquired pursuant to such transaction (as determined in good faith by the Company) is 2.5 to 1.0 or less, and does not exceed (together with all Permitted
Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (14)) $20.0 million in the aggregate at any one time outstanding; 

  
 47

(c) The Company shall not incur, and shall not permit the Issuer or any other Guarantor to incur, any Indebtedness
(including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company, the Issuer or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and
the Note Guarantees on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of
being secured on junior priority basis or junior in right of distribution of collateral proceeds. 
 (d) For
purposes of determining compliance with this Section 4.09 and Section 4.12 hereof, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through
(16) of Section 4.09(b) hereof, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company shall be permitted (in its sole discretion) to classify such item of Indebtedness on the date of its incurrence, or later
reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant. Notwithstanding the foregoing, (x) all Priority Lien Debt will be deemed to have been incurred in reliance on the exception provided by
clause (1) of the definition of Permitted Debt and (y) all Parity Lien Debt outstanding on the date of this Indenture (including all Initial Notes) and all Parity Lien Debt represented by the Exchange Notes issued pursuant to the Exchange
Agreement will be deemed to have been incurred in reliance on the exception provided by clause (2) of the definition of Permitted Debt (provided, however, that such Parity Lien Debt under clause (y) of this sentence that is still
outstanding shall be taken into account in accordance with clause (1) of the definition of Parity Lien Cap in determining the amount of Parity Lien Debt that is available under clause (3) of the definition of Permitted Debt). The accrual
of interest or preferred stock or Disqualified Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of
preferred stock or Disqualified Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or
Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.09; provided, in each such case,

  
 48 

 
that the amount of any such accrual, accretion or payment is included in Consolidated Interest Expense of the Company as accrued. 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 utilized, calculated based on the relevant currency exchange rate in effect on
the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that (x) the U.S. dollar-equivalent principal amount of Existing Indebtedness
denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date of this Indenture, and (y) if such Indebtedness is incurred to renew, refund, refinance, replace, defease or discharge
other Indebtedness denominated in a foreign currency (or in a different currency from such Indebtedness so being incurred), and such renewal, refunding, refinancing, replacement, defeasance or discharge 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 renewal, refunding, refinancing, replacement, defeasance or discharge, such U.S. dollar-denominated restriction shall be
deemed not to have been exceeded so long as the principal amount of such new Indebtedness does not exceed (i) the outstanding or committed principal amount (whichever is higher) of such Indebtedness being renewed, refunded, refinanced,
replaced, defeased, or discharged plus (ii) the aggregate amount of accrued interest and fees, underwriting discounts, premiums and other costs and expenses incurred in connection with such renewal, refunding, refinancing,
replacement, defeasance or discharge. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to
be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 (e) The amount of any
Indebtedness outstanding as of any date will be: 
 (1) the accreted value of the Indebtedness (other than net
Hedging Obligations), in the case of any Indebtedness issued with original issue discount; 
 (2) the principal
amount of the Indebtedness (other than net Hedging Obligations), in the case of any other Indebtedness; 
 (3)
in respect of net Hedging Obligations, the termination value of the related Hedge Agreement that would be payable by the applicable Person as of such date; 
 (4) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: 

(A) the Fair Market Value of such assets at the date of determination; and 

(B) the amount of such Indebtedness of the other Person; and 

  
 49 

 (5) in respect of Disqualified Stock, an amount equal to the greater of its
voluntary or involuntary liquidation preference and its maximum fixed repurchase price, but excluding accrued dividends, if any.” 
 (dd) The Indenture shall be amended to restate in its entirety Section 4.10 as follows: 
 “Section 4.10 Asset Sales. 
 (a) The Company shall not,
and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) The Company
(or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or
Equity Interests issued or sold or otherwise disposed of; 
 (2) except in the case of a Permitted Asset Swap,
at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents; 
 For purposes of this Section 4.10(a)(2), each of the following will be deemed to be cash:

further liability; 
 (B) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as

(C) any securities, Notes or other obligations received by the Company or any such Restricted Subsidiary from such
transferee that are converted by the Company or such Restricted Subsidiary into cash within one hundred twenty (120) days after such Asset Sale, to the extent of the cash received in that conversion; and 

(D) any stock or assets of the kind referred to in clause (3), (5) or (6) of paragraph (b) of this
Section 4.10; and 

  
 50 

 (3) subject to certain limitations, in the case of an Asset Sale that
constitutes a Sale of Collateral, the Company (or the applicable Restricted Subsidiary, as the case may be) promptly deposits the Net Proceeds therefrom promptly upon receipt thereof as Collateral in an account or accounts held by or under the
control of (for purposes of the Uniform Commercial Code) or otherwise subject to a perfected security interest in favor of the Collateral Trustee or its agent to secure all Secured Obligations. 

(b) Within three hundred sixty-five (365) days after the receipt of any Net Proceeds from an Asset Sale other than a
Sale of Collateral, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds, at its option: 
 (1) to repay, repurchase or redeem Priority Lien Obligations and, if the Priority Lien Obligations repaid are revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

 (2) to repay, repurchase or redeem Parity Lien Obligations; provided, that the Issuer offers to repay,
repurchase or redeem the Notes on a pro rata basis; 
 (3) to acquire all or substantially all of the assets of,
or any Equity Interests of, a Permitted Business (provided that in the case of any such acquisition of Equity Interests, after giving effect thereto, the Permitted Business is or becomes a Restricted Subsidiary of the Company); 

(4) to repay (A) Indebtedness (other than Secured Obligations) that is secured by a Permitted Lien on any assets
that were sold in such Asset Sale, or (B) obligations under the 13% Notes; 
 (5) to make a capital
expenditure; 
 (6) to acquire other assets that are not classified as current assets under GAAP and that are
used or useful in a Permitted Business;

not a Guarantor, to repay, repurchase or redeem Indebtedness of the Company, the Issuer or any Restricted Subsidiary; or 
 (8) any combination of the foregoing clauses (1) through (7). 

(c) Within three hundred sixty-five (365) days after the receipt of any Net Proceeds from a Sale of Collateral, the
Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds, at its option: 
 (1) to purchase other assets that would constitute Collateral; 

(2) to acquire all or substantially all of the assets of, or any Equity Interests of, a Permitted Business
(provided that in the case of any such acquisition of Equity Interests, after giving effect thereto, the Permitted Business becomes a Guarantor or is merged into or consolidated with the Issuer or any Guarantor); 

  
 51 

 (3) to repay (A) Indebtedness (other than Secured Obligations) that is
secured by a Permitted Priority Lien on any Collateral that was sold in such Sale of Collateral, or (B) obligations under the 13% Notes; 
 (4) to make a capital expenditure with respect to assets that constitute Collateral; or 
 (5) any combination of the foregoing clauses (1) through (4). 

(d) In the case of clauses (3), (5) and (6) of paragraph (b) of this Section 4.10 and clauses (1),
(2) and (4) of paragraph (c) of this Section 4.10, the Company (or the applicable Restricted Subsidiary, as the case may be) will be deemed to have complied with its obligations in paragraphs (b) and (c) of this
Section 4.10 if it enters into a binding commitment to acquire such assets or Equity Interests prior to three hundred sixty-five (365) days after the receipt of the applicable Net Proceeds; provided that such binding commitment will be
subject only to customary conditions and such acquisition is completed within one hundred eighty (180) days following the expiration of the aforementioned three hundred sixty-five (365) day period. If the acquisition contemplated by such
binding commitment is not consummated on or before such one hundred eightieth (180th) day, and the Company (or the applicable Restricted Subsidiary, as the case may be) has not applied the applicable Net Proceeds for another purpose permitted
by the applicable paragraph (b) or (c) of this Section 4.10 on or before such one hundred eightieth (180th) day, such commitment shall be deemed not to have been a permitted application of Net Proceeds. 

(e) Pending the final application of any Net Proceeds of an Asset Sale, other than a Sale of Collateral, the Company (or
the applicable Restricted Subsidiary) may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 

(f) Any Net Proceeds from Asset Sales that are not applied or invested as provided in paragraph (b) (with respect to
Asset Sales other than Sales of Collateral) or paragraph (c) (with respect to a Sale of Collateral) of this Section 4.10 constitute “Excess Proceeds”. 

(g) When the aggregate amount of Excess Proceeds exceeds $15.0 million, within forty-five (45) days thereof, the
Issuer will make an offer (an “Asset Sale Offer”) to all Holders and all holders of other Parity Lien Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with
the proceeds of sales of assets, in accordance with Section 3.08 hereof, to purchase, prepay or redeem the maximum principal amount of Notes and such other Parity Lien Debt (plus all accrued interest on the Indebtedness and the
amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, 

  
 52 

 
prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest to the date
of purchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an
Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other Parity Lien Debt tendered into (or required to be prepaid or redeemed in
connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other Parity Lien Debt to be purchased on a pro rata basis, based on the amounts validly tendered (and not validly
withdrawn) or required to be prepaid or redeemed. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 (h) The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in
connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of Section 3.08 hereof or this Section 4.10, the
Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.08 hereof or this Section 4.10 by virtue of such compliance.”

(ii) The Indenture shall be amended to restate in its entirety Section 4.15 as follows: 

“Section 4.15 Offer to Repurchase Upon a Change of Control. 

  
 55

require the Issuer to repurchase all or any part of that Holder’s Notes (equal to $2,000 or an integral multiple of $1 in excess thereof) pursuant to this Section 4.15 (a “Change of Control Offer”). In the Change of
Control Offer, the Issuer will offer the Holders a purchase price in cash equal to 100% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase,

unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1 in excess thereof. 

  
 56 

 The Issuer will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of this Section 4.15, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by
virtue of such compliance.

Section 3.01 hereof, unless and until there is a default in payment of the applicable redemption price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control,
conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.” 

(jj) The Indenture shall be amended to restate in its entirety Section 4.17 as follows:

(a) Subject to Section 4.17(c), the Board of Directors of the Company may designate any Restricted Subsidiary to be

by the Company and its Restricted Subsidiaries in the 

  
 57 

 
Subsidiary designated as an Unrestricted Subsidiary shall be deemed to be an Investment made as of the time of the designation and shall reduce the amount available for Restricted Payments under
Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
 (b) Any designation of a Subsidiary
of the Company as an Unrestricted Subsidiary shall be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate of the Company
certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the
Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted
if (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be
in existence following such designation. 
 (c) The Company shall not designate (1) any Australian
Subsidiary to be an Unrestricted Subsidiary other than Australian Subsidiaries (together with all other Australian Subsidiaries that constitute Unrestricted Subsidiaries) (i) that, as of the date of such designation, own less than 10% of the
assets owned by all Australian Subsidiaries as of the end of the four-quarter period immediately preceding such date and for which financial information is available, and (ii) from which, as of the date of such designation, less than 10% of
Australian Net Income and Australian EBITDA of all Australian Subsidiaries are derived, in each case, for the four-quarter period immediately preceding such date and for which financial information is available, and (2) any Canadian Subsidiary
to be an Unrestricted Subsidiary other than Canadian Subsidiaries (together with all other Canadian Subsidiaries that constitute Unrestricted Subsidiaries) (i) that, as of the date of such designation, own less than 10% of the assets owned by
all Canadian Subsidiaries as of the end of the four-quarter period immediately preceding such date and for which financial information is available, and (ii) from which, as of the date of such designation, less than 10% of Canadian Net Income
and Canadian EBITDA of all Canadian Subsidiaries are derived, in each case, for the four-quarter period immediately preceding such date and for which financial information is available; provided that, in the case of each of clauses (1) and
(2) above, such Subsidiaries otherwise satisfy all of the criteria to be designated as “Unrestricted Subsidiaries” pursuant to this covenant.” 
 (kk) The Indenture shall be amended to restate in its entirety Section 4.18 as follows:

to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such
consideration is offered to be paid and is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.”

agree to take such actions as may be necessary to amend this Indenture, Notes and Security Documents in order to provide the same (or, at the consent of the Holders of a majority of the principal amount of the Exchange Notes and any Exchange
Additional Notes issued to other Holders of Initial Notes upon exchange of such Initial Notes for Exchange Additional Notes following the consummation of the exchange of Initial Notes for Exchange Notes contemplated by the Exchange Agreement,
substantially similar) additional rights or benefits under the Exchange Notes and any Exchange Additional Notes issued to Holders of Initial Notes following the consummation of the exchange of Initial Notes for Exchange Notes contemplated by the
Exchange Agreement. Notwithstanding the foregoing, the following terms with respect to future issuances of Parity Lien Debt will not be deemed to be more favorable to the holders of such Parity Lien Debt than the Exchange Notes: (i) the
issuance of Initial Additional Notes or Exchange Additional Notes at an issue price equal to or greater than 100% of the principal amount thereof (for the avoidance of doubt, (A) this exception under clause (i) shall not apply to any term
or provision of the Initial Additional Notes or Exchange Additional Notes other than the issue price and (B) the issuance or incurrence of any Parity Lien Debt (other than the Initial Notes that were issued on the date on which this Indenture
was executed) with call protection or a prepayment penalty shall trigger the requirements under the first sentence of this Section 4.19) and (ii) the issuance of Exchange Additional Notes to other Holders of Initial Notes following the
consummation of the exchange of Initial Notes for Exchange Notes contemplated by the Exchange Agreement, upon the exchange of any such Initial Notes at an exchange rate (together with accrued but unpaid interest to the date of exchange, if

4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17 and 4.18 and clauses (4), (5), (6) and (7) of Section 5.01(a) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are

in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed

with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any
such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and
such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in

principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default
or Event of Default (other than a Default or Event of Default in the payment of the principal of, or premium or interest, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection
with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.”

or waiver of, the provisions of this Indenture or any Security Document that has the effect of releasing all or substantially all of the Collateral from the Liens securing the Notes will require the consent of the Holders of at least
66 2/3% in aggregate principal amount of the Notes then outstanding and (y) any amendment to, or waiver of, Section 4.19 of this Indenture shall require the consent of each Holder of the Exchange
Notes and each Holder of Exchange Additional Notes which were issued in exchange for Initial Notes following the consummation of the exchange of Initial Notes for Exchange Notes contemplated by the Exchange Agreement.” 

(bbb) The Indenture shall be amended to add the following sentence at the end of Section 10.01(a):

entirety Section 10.04 as follows:

Section 4.10 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge or amalgamate with or into (whether or not such Guarantor is the surviving Person) another Person, other
than the Company or another Guarantor, unless: 
 (a) immediately after giving effect to that transaction, no
Default or Event of Default exists; and 
 (b) either: 

(1) (A) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any
such consolidation or merger or amalgamation (the “Successor Guarantor”) assumes all the obligations of that Guarantor under its Note Guarantee, this Indenture, and the applicable Security Documents pursuant to a supplemental
indenture and appropriate Security Documents satisfactory to the Trustee, (B) the Successor Guarantor causes such amendments, supplements or other instruments to be executed, delivered, filed and recorded in such jurisdictions as may be
required by applicable law to preserve and protect the Liens under the applicable Security Documents on the Collateral owned by or transferred to the Successor Guarantor, together with such financing statements as may be required to perfect any
security interests in such Collateral which may be perfected by the filing of a financing statement under the Uniform Commercial Code of the relevant jurisdiction; (C) the Collateral owned by or transferred to the Successor

  
 66 

 
Guarantor shall: (i) continue to constitute Collateral under this Indenture and the applicable Security Documents, (ii) be subject to Liens in favor of the Collateral Trustee for the
benefit of the Holders and any other Parity Lien Indebtedness or Priority Lien Indebtedness and (iii) not be subject to any other Lien other than Permitted Liens; and (D) the property and assets of the Person which is merged or
consolidated with or into the Successor Guarantor, to the extent that they are property or assets of the types which would constitute Collateral under the applicable Security Documents, shall be treated as after-acquired property and the Successor
Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Lien of the applicable Security Documents in the manner and to the extent required under this Indenture and the Security
Documents; or 
 (2) the Net Proceeds of such sale or other disposition are applied in accordance with the
applicable provisions of this Indenture, including without limitation, Section 4.10 hereof. 
 In case of
any such consolidation, merger, amalgamation, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of the Note
Guarantee endorsed upon the applicable Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor
with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the applicable Notes issuable hereunder which theretofore shall
not have been signed by the Issuer and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance
with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. 
 Except as set forth in Articles 4 and 5 hereof, notwithstanding clauses (b)(1) and (2), nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor
with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.” 

(ddd) The Indenture shall be amended to restate in its entirety Sections 10.05(a) and Section 10.05(b) as follows: 

“(a) In the event of any sale or other disposition of all or substantially all of the assets of any Subsidiary
Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate
Section 4.10 hereof and is permitted by all of the Secured Debt Documents then the Person acquiring the property will be released and relieved of any obligations under the applicable Note Guarantee; 

  
 67 

 (b) in the event of any sale or other disposition of Capital Stock of any
Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.10 hereof and is
permitted by all of the Secured Debt Documents and the Subsidiary Guarantor ceases to be a Restricted Subsidiary of the Company as a result of the sale or other disposition, then such Subsidiary Guarantor will be released and relieved of any
obligations under its Note Guarantee; 
 provided, in both cases, that the Net Proceeds of such sale or other disposition
are applied in accordance with Section 4.10 hereof. Upon delivery by the Issuer to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Guarantor in accordance
with the provisions of this Indenture, including without limitation Section 4.10 hereof, the Trustee will execute any documents reasonably required in order to evidence the release of the Guarantor from its obligations under its Note
Guarantee.”

Section 4.10 hereof and is permitted by all of the other Security Documents, at the time of such sale, transfer or other disposition or to the extent of the interest sold, transferred or otherwise disposed of; provided that the
Collateral Trustee’s Liens upon the Collateral will not be released if the sale or disposition is subject to Section 5.01 hereof;”

Notes, the Exchange Notes and the Additional Notes; and 

  
 68 

 (2) all proceeds of all Parity Liens granted at any time by the Issuer or
any Guarantor will be allocated and distributed equally and ratably on account of the Parity Lien Debt (including without limitation, under the Initial Notes, the Exchange Notes and the Additional Notes) and other Parity Lien Obligations.”

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise
indicated. 
 (1) INTEREST. Primus Telecommunications Holding, Inc., a
Delaware corporation (the “Issuer”), promises to pay or cause to be paid interest on the principal amount of this Note at 10.00% per annum. The Issuer will pay interest, if any, semiannually in arrears on April 15 and
October 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date on which interest has been
paid or, if no interest has been paid, from the date of original issuance; provided that, if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue
from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be October 15, 2011. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law)
on overdue principal at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 

(2) METHOD OF PAYMENT. The Issuer will pay interest on
the Notes (except defaulted interest), if any, to the Persons who are registered Holders at the close of business on the April 1 or October 1 immediately preceding the Interest Payment Date, even if such Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the office or
agency of the Paying Agent and Registrar within the City and State of New York, or, at the option of the Issuer, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders;
provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium on, if any, and interest, if any, on all Global Notes and all other Notes the Holders of which will have provided
wire transfer instructions to the Issuer or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

(3) PAYING AGENT AND REGISTRAR.
Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change the Paying Agent or Registrar without prior notice to the Holders. The Issuer, the Company or any of its
Subsidiaries may act as Paying Agent or Registrar. 
 (4) INDENTURE AND
SECURITY DOCUMENTS. The Issuer issued the Notes under an Indenture, dated as of July 7, 2011 (as amended from time to time, the “Indenture”), by and among the Issuer, the guarantors party
thereto, and U.S. Bank National Association as Trustee and as Collateral Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of
such terms. To the extent any provision of this Note conflicts with the express provisions of the 

  
 A-1-2

 
Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured obligations of the Issuer. The Notes are secured by substantially all the assets of the Issuer
and the applicable Guarantors pursuant to and as further described in the Security Documents referred to in the Indenture. Subject to Sections 2.02, 2.13, 4.09 and 4.12 thereof, the Indenture does not limit the aggregate principal amount of Notes
that may be issued thereunder.

(a) Optional Redemption Upon an Equity Offering. At any time prior to March 15, 2013, the Issuer may, at its
option, on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes issued under the Indenture, upon not less than thirty (30) nor more than sixty (60) days’ notice, with respect to this Note, at a
redemption price equal to 110.00% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the rights of Holders on the relevant record date to receive interest on
the relevant interest payment date) with the net cash proceeds of an Equity Offering by the Company; provided that: 
 (i) at least 65% of the original aggregate principal amount of the Notes issued under the Indenture (including the principal amount of any Additional Notes issued under the Indenture) remains outstanding

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless
otherwise indicated. 
 (1) INTEREST. Primus Telecommunications Holding,
Inc., a Delaware corporation (the “Issuer”), promises to pay or cause to be paid interest on the principal amount of this Note at 10.00% per annum. The Issuer will pay interest, if any, semiannually in arrears on April 15
and October 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date on which interest has
been paid or, if no interest has been paid, from the date of original issuance; provided that, if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be April 15, 2013. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy
Law) on overdue principal at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 
 Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Issuer will pay interest on the Notes (except defaulted interest), if any, to the Persons who are registered
Holders at the close of business on the April 1 or October 1 immediately preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the office or agency of the Paying Agent and Registrar within the City and State of New York,
or, at the option of the Issuer, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be
required with respect to principal of, premium on, if any, and interest, if any, on all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent. Such payment will be in
such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 (3) PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as
Paying Agent and Registrar. The Issuer may change the Paying Agent or Registrar without prior notice to the Holders. The Issuer, the Company or any of its Subsidiaries may act as Paying Agent or Registrar. 

(4) INDENTURE AND SECURITY DOCUMENTS. The Issuer issued
the Notes under an Indenture, dated as of July 7, 2011 (as amended from time to time, the “Indenture”), by and among the Issuer, the guarantors party thereto, and U.S. Bank National Association as Trustee and as Collateral
Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the
express provisions of the 

  
 A-2-2

 
Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured obligations of the Issuer. The Notes are secured by substantially all the assets of the Issuer
and the applicable Guarantors pursuant to and as further described in the Security Documents referred to in the Indenture. Subject to Sections 2.02, 2.13, 4.09 and 4.12 thereof, the Indenture does not limit the aggregate principal amount of Notes
that may be issued thereunder.

Note, at a redemption price equal to 100.00% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the rights of Holders on the relevant record date to receive
interest on the relevant interest payment date) with the net cash proceeds of an Equity Offering by the Company; provided that: 
 (i) at least 65% of the original aggregate principal amount of the Notes issued under the Indenture (including the principal amount of any Additional Notes issued under the Indenture) remains outstanding

 Exhibit 10.1 
 NOTE EXCHANGE AND CONSENT AGREEMENT 
 NOTE EXCHANGE AND CONSENT
AGREEMENT, dated as of November 14, 2012 (this “Agreement”), by and among Primus Telecommunications Holding, Inc. (the “Company”), the Guarantors and each of the parties listed on the signature pages hereto
(each a “Noteholder”, and collectively, the “Noteholders”). Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to such terms in the Indenture (as defined herein). 

WHEREAS, the Company has previously issued its 10% Senior Secured Notes due 2017 (the “10% Notes”) pursuant to
the Indenture, dated as of July 7, 2011, among the Company, the Guarantors and U.S. Bank National Association, as Trustee and as Collateral Agent (the “Trustee”), as amended by the First Supplemental Indenture, dated as of
September 17, 2012, by and among the Company, the Guarantors and the Trustee (such Supplemental Indenture, the “First Supplemental Indenture”) (as so supplemented, the “Indenture”). 

WHEREAS, each Noteholder beneficially owns the aggregate principal amount of 10% Notes set forth in the written instrument
executed by such Noteholder and delivered to the Company contemporaneously with the execution and delivery of this Agreement (each such instrument, a “Noteholder Letter” and with the 10% Notes referenced in the Noteholder Letter
being referred to herein as such Noteholder’s “Subject Notes”), representing in the aggregate a majority of the outstanding principal amount of the 10% Notes; 

WHEREAS, Section 9.02 of the Indenture provides that the Company, the Guarantors and the Trustee may amend certain provisions
of the Indenture and the 10% Notes outstanding thereunder with the written consent of the Holders of at least a majority in principal amount of the 10% Notes then outstanding; 
 WHEREAS, the Noteholders, the Company and the Guarantors desire to enter into this Agreement to provide for, among other things, the consent of the Noteholders to the proposed amendments (the
“Proposed Amendments”) to the Indenture, as set forth in the Second Supplemental Indenture among the Company, the Guarantors and the Trustee, a form of which is attached hereto as Annex A (“Second Supplemental
Indenture”), including the establishment of 10.00% Senior Secured Exchange Notes due 2017 (the “10% Exchange Notes), which 10% Exchange Notes shall be in all respects substantially identical to the 10% Notes, except that
(x) the 10% Exchange Notes shall at all times be redeemable at the option of the Company at a redemption price equal to 100% of the principal amount thereof plus accrued and unpaid interest thereon to the date of redemption and (y) only
the holders of 10% Exchange Notes shall have the benefit of the rights provided under paragraph 6 hereof (and the similar provision set forth in the Second Supplemental Indenture); and 

WHEREAS, immediately after this Agreement and the Second Supplemental Indenture are executed, each of the Noteholders will
exchange its 10% Notes for 10% Exchange Notes, and the Company will issue such 10% Exchange Notes in exchange, at the rate of $1,090 principal amount of 10% Exchange Notes for each $1,000 principal amount of 10% Notes exchanged (the exchange rate of
1.09, the “Exchange Rate”) and otherwise in accordance with the terms and conditions of this Agreement (the “Note Exchange”). 

 NOW, THEREFORE, in consideration of the premises and the representations, warranties
and agreements contained herein, the parties hereto agree as follows: 
 1. Consents. Effective as of the date hereof,
each Noteholder, with respect to all 10% Notes beneficially owned by such Noteholder, hereby irrevocably consents to the Proposed Amendments referenced in the Second Supplemental Indenture. 

2. Note Exchange. Immediately after the execution and delivery of the Second Supplemental Indenture, the parties shall effectuate
the Consummation in the following manner: (a) the Company shall issue and deliver to the Trustee, and shall cause the Trustee to authenticate and deliver and hold as custodian for The Depository Trust Company, to be credited to the accounts of
the Noteholders specified in the applicable Noteholder Letters, an aggregate principal amount of 10% Exchange Notes equal to the aggregate principal amount of the Subject Notes exchanged hereunder multiplied by the Exchange Rate and (b) the
Noteholders, severally (and not jointly) in accordance with the second to last sentence of this paragraph 2, shall deliver to the Company all of their respective Subject Notes (the “Exchanged 10% Notes”) by causing their DTC
participants to effect a deposit/withdrawal at custodian of the Exchanged 10% Notes to the Trustee. In addition, the Company shall pay accrued but unpaid interest on the Exchanged 10% Notes for the period from October 15, 2012 to, but not
including, the date of exchange, in cash, in accordance with the second to last sentence of this paragraph 2 (“Cash Interest Payment”). The 10% Exchange Notes shall bear interest from the date of issuance. Immediately after
the execution and delivery of the Second Supplemental Indenture, each Noteholder severally (and not jointly) shall deliver its Subject Notes in accordance with this paragraph 2 and, upon such delivery, (i) shall receive (x) an
aggregate principal amount of 10% Exchange Notes equal to the principal amount of the Subject Notes that it exchanged hereunder multiplied by the Exchange Rate and (y) its portion of the Cash Interest Payment and (ii) the BR/WC Legal Fees
shall be paid to Brown Rudnick LLP and/or Womble Carlyle Sandridge & Rice, LLP and/or reimbursed to the Noteholders, as applicable. The parties hereto agree that the Note Exchange is being consummated as consideration for the dismissal of
the Delaware Litigation (as defined herein).

bound, or (iii) any laws, regulations or governmental or judicial decrees, injunctions or orders applicable to any Obligor. 
 (c) Validity of 10% Exchange Notes. The 10% Exchange Notes issued pursuant to this Agreement, when authenticated by the Trustee and delivered in exchange for the Exchanged 10% Notes in accordance

other similar laws relating to or affecting creditors’ rights generally, and general equitable principles (whether considered in a proceeding in equity or at law). 

(d) Compliance with Stipulation. The Obligors have complied in all respects with the Stipulation (as defined
herein). 
 (e) Dividends. $14,262,992 of Restricted Payments were issued from the date on which the
Indenture was executed through the date hereof and, since July 7, 2011, the Company has not (x) paid or declared or entered into any agreement or understanding to pay or declare any other dividends or other distributions in respect of its
capital stock or (y) entered into any agreement or understanding to make a Restricted Payment that otherwise would not have been permitted under the Indenture (before giving effect to the First Supplemental Indenture and the Second Supplemental
Indenture). 
 (f) Parity Lien Debt. As of the date hereof, $116,195,491 of Parity Lien Debt is
outstanding before giving effect to the Note Exchange and, since July 7, 2011, Company has not issued or entered into any agreement or understanding to incur any additional Parity Lien Debt except as set forth herein and the Second Supplemental

 4. Representations and Warranties of the Noteholders. Each Noteholder hereby, severally and not jointly, represents and
warrants to the Company as of the date hereof and as of the consummation of the Note Exchange as follows: 
 (a)
Due Organization. Such Noteholder is duly organized and validly existing under the laws of the jurisdiction of its organization. 

  
 3 

 (b) Due Authorization; Binding Agreement. Such Noteholder has full
right, power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. This Agreement has been duly and validly authorized, executed and delivered by such Noteholder and (assuming due authorization,
execution and delivery by the Company) constitutes the valid and binding obligation of such Noteholder enforceable against such Noteholder in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, and general equitable principles (whether considered in a proceeding in equity or at law). 

(c) Ownership of the Subject Notes. Such Noteholder is the beneficial owner of all of its Subject Notes, free and
clear of any adverse claim, mortgage, pledge, lien, encumbrance, option, charge or other security interest that would prevent such Noteholder’s compliance with its obligations hereunder. Such Noteholder does not own, beneficially or of record,
any 10% Notes of the Company or securities convertible or exchangeable for 10% Notes of the Company other than as set forth in the applicable Noteholder Letter. Such Noteholder has the sole right and power to vote and dispose of the Subject Notes,
and none of such Subject Notes is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting or transfer of any of the Subject Notes, except for this Agreement. 

(d) Intentionally Omitted. 
 (e) Investment Intent. The 10% Exchange Notes to be acquired by such Noteholder pursuant to this Agreement shall be acquired for such Noteholder’s own account and not with a view to, or

investment in the 10% Exchange Notes for an indefinite period of time and acknowledges that no public market exists for the 10% Exchange Notes and that there is no assurance that a public market will ever develop for the 10% Exchange Notes. The 10%
Exchange Notes have not been registered under the Securities Act and, therefore, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available. 

(g) Information. Such Noteholder has reviewed, or has had the opportunity to review, with the assistance of
professional and legal advisors of its choosing, sufficient information (including all documents filed or furnished to the SEC by Primus Telecommunications Group, Incorporated) and has had sufficient access to the Company necessary for such
Noteholder to decide to grant its consent to the Proposed Amendments and exchange its 10% Notes for 10% Exchange Notes in accordance with this Agreement. 
 5. Intentionally Omitted.

 6. Parity Lien Debt. In the event of the incurrence of Parity Lien Debt following the
execution and delivery of the Second Supplemental Indenture (including the issuance of any additional Notes under the Indenture), having any terms and conditions more favorable to the holders of such Parity Lien Debt than the terms and conditions of
the 10% Exchange Notes, the Company and Guarantors agree to take such actions as may be necessary to amend the Indenture, Notes and Security Documents in order to provide the same (or, with the consent of the Required Noteholders, substantially
similar) additional rights or benefits under the 10% Exchange Notes. Notwithstanding the foregoing, the following terms with respect to future issuances of Parity Lien Debt will not be deemed to be more favorable to the holders of such Parity Lien
Debt than the 10% Exchange Notes: (i) the issuance of additional 10% Notes or 10% Exchange Notes at an issue price equal to or greater than 100% of the principal amount thereof (for the avoidance of doubt, (A) the exception under clause
(i) shall not apply to any term or provision of the 10% Notes or 10% Exchange Notes other than the issue price and (B) the issuance or incurrence of any Parity Lien Debt (other than the 10% Notes that were issued on the date on which the
Indenture was executed) with call protection or a prepayment penalty shall trigger the requirements under the first sentence of this paragraph 6) and (ii) the issuance of 10% Exchange Notes to other holders of 10% Notes following the
consummation of the Note Exchange, upon the exchange of any such 10% Notes at an exchange rate (together with accrued but unpaid interest to the date of exchange, if applicable) not more favorable to such other holders than the Exchange Rate
applicable to the Exchanged 10% Notes. 
 7. Delaware Litigation. Contemporaneously with the execution and delivery of
this Agreement, Whitebox Advisors, LLC and Riva Ridge Master Fund Ltd. and all other applicable Noteholders shall deliver a notice of dismissal in the form attached as Annex B hereto (the “Notice of Dismissal”) in the action
captioned Whitebox Advisors, LLC and Riva Ridge Master Fund Ltd. v. Primus Telecommunications Holdings, Inc., C.A. No. 7871-VCG currently pending in the Court of Chancery of the State of Delaware (the “Delaware
Litigation”). The Notice of Dismissal shall be filed as soon as practicable following the consummation of the transactions contemplated hereby, which consummation shall take place contemporaneously with the execution and delivery of this
Agreement. The parties hereto agree that this Agreement and the transactions contemplated by it, and any action or inaction to be taken by U.S. Bank National Association acting as Trustee or Collateral Agent in connection with the transactions
contemplated hereunder, are not prohibited by the Order of the Court of Chancery of the State of Delaware dated September 28, 2012 (the “Stipulation”), and in the event any court having jurisdiction determines that any action
or inaction taken in connection with the transactions contemplated hereunder is not permitted by the Stipulation (or otherwise), U.S. Bank National Association is authorized to take any action or inaction in order to comply with such determination
by the applicable court. U.S. Bank National Association, as Trustee and as Collateral Agent, shall be a third party beneficiary of the preceding sentence. 
 8. Lien Sharing and Priority Confirmation. The Noteholders and the Obligors acknowledge and agree, for the enforceable benefit of all Holders of each existing and future Series of Secured Debt and
each existing and future Secured Debt Representative: (A) that the 10% Exchange Notes are Notes issued under the Indenture and the obligations thereunder constitute Parity Lien Obligations for all purposes under the Indenture, the Notes and the
Security Documents; and (B) that all Parity Lien Obligations will be and are secured equally and ratably by all Parity Liens at any time granted by the Company or any Guarantor to secure any Parity Lien Obligations whenever incurred and that
all such Parity Liens will be enforceable by the Collateral Trustee for the benefit of all holders of Parity Lien Obligations equally and ratably.

and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express

deemed to be outstanding for purposes of Section 3.01(a) hereof. 
 If a Note is replaced pursuant to
Section 2.07 hereof, it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note
and replacement thereof pursuant to Section 2.07. If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 

If the Paying Agent (other than the Issuer, the Company or a Subsidiary of the Company) holds, on a redemption date or

unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the
failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid
principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.” 
 (u) The Indenture shall be
amended to restate in its entirety Section 3.07 as follows:

commencement and not more than thirty (30) Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five (5) Business Days after the termination of the
Offer Period (the “Purchase Date”), the Issuer will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other Parity Lien Debt (on a pro rata basis based on the principal amount
of Notes and such other Parity Lien Debt surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer.

Purchase Date;

the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for
purchase, the serial number of such Note if held in definitive form, and a statement that such Holder is withdrawing his election to have such Note purchased;

basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee
the Notes properly accepted together with an Officers’ Certificate of the Issuer stating that such Notes or portions thereof were accepted for payment by the

Discussion and Analysis of Financial Condition and Results of Operations,” (B) audited financial statements prepared in accordance with GAAP, and (C) a presentation of Consolidated EBITDA of the Company and its Restricted Subsidiaries

Section 6.01(d), (1) the Company will be deemed not to have failed to comply with any of its obligations under paragraph (a)(1) of this Section 4.03 until fifteen (15) days after the date any financial statements or reports
thereunder are due, and (2) the Company will be deemed not to have failed to comply with any of its obligations under paragraph (a)(2) of this Section 4.03 until five (5) days after the date any financial statements or reports
thereunder are due.

informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of
its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).”

(b) The provisions of Section 4.07(a) hereof will not prohibit: 

(1) the payment of any dividend or the consummation of any irrevocable redemption within sixty (60) days after the

 41 

 (bb) The Indenture shall be amended to restate in its entirety Section 4.08 as
follows: 
 “Section 4.08 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

 (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly,
create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Equity Interests to the Company or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by,
its profits, or pay any indebtedness owed to the Company or any of its Restricted Subsidiaries; 
 (2) make
loans or advances to the Company or any of its Restricted Subsidiaries; or 
 (3) sell, lease or transfer any of
its properties or assets to the Company or any of its Restricted Subsidiaries (provided that dividend or liquidation priority between classes of Equity Interests, or subordination of any obligation (including the application of any remedy bars
thereto) to any other obligation, will not be deemed to constitute such an encumbrance or restriction). 
 (b)
The restrictions in Section 4.08(a) hereof will not apply to encumbrances or restrictions existing under or by reason of: 
 (1) agreements governing Existing Indebtedness as in effect on the date of this Indenture and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings
of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other
payment restrictions than those contained in those agreements on the date of this Indenture (as determined in good faith by the Company); 
 (2) this Indenture, the Notes, the Note Guarantees, the Secured Debt Documents and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of any of
the foregoing; 
 (3) (A) agreements governing other Indebtedness permitted to be incurred under
Section 4.09(b)(15) hereof and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that in the case of this sub-clause (A), the restrictions therein
would not (i) impair, in the Issuer’s good faith reasonable judgment, the ability of the Issuer and the Guarantors to satisfy the Obligations under the Notes, or (ii) otherwise prohibit the Subsidiaries from paying dividends or making
distributions, loans or advances at any time in an amount, together with other 

  
 42 

 
amounts available, sufficient to make payments on the Notes due at such time, and (B) agreements governing other Indebtedness permitted to be incurred under Section 4.09(b) other than
clause (15) thereof, and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that in the case of this sub-clause (B), the restrictions therein are not

(4) applicable law, rule, regulation or order; 

(5) any agreement governing or relating to Indebtedness or Equity Interests of Persons acquired by the Company or any of
its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Equity Interests were incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not
applicable to any Persons, or the properties or assets of any Persons, other than the Persons, or the property or assets of the Persons, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of
this Indenture to be incurred, and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals,
supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of such acquisition (as

 (6) non-assignment provisions in contracts, leases, subleases,
licenses and sublicenses entered into in the ordinary course of business; 
 (7) mortgage financings and
purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose restrictions on the property mortgaged, purchased or leased of the nature described in clause (3) of the preceding
paragraph;

entered into for the sale or disposition of all or substantially all of the Equity Interests or assets of such Restricted Subsidiary pending the closing of such sale or disposition; 

(9) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such
Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced (as determined in good faith by the Company); 

  
 43 

 (10) Liens permitted to be incurred under the provisions of
Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens; 

(11) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale
agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment), which limitation is applicable only to the assets that are the subject of such
agreements; 
 (12) restrictions on cash or other deposits or net worth imposed by customers under contracts
entered into by the Company or any Restricted Subsidiary; 
 (13) encumbrances and restrictions contained in the
terms of any Indebtedness or any agreement pursuant to which such Indebtedness was issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in such Indebtedness
or agreement and such encumbrance or restriction is not materially more disadvantageous to the holders of the Notes than is customary in comparable financings (as determined in good faith by the Company) and the Company determines that any such
encumbrance or restriction will not materially affect the Issuer’s ability to make principal or interest payments on the Notes; and 
 (14) restrictions on the sale, lease or transfer of property or assets arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the
aggregate, detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary.” 
 (cc) The Indenture shall be amended to restate in its entirety Section 4.09 as follows: 
 “Section 4.09 Incurrence of Indebtedness and Issuance of Disqualified Stock. 
 (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company shall not and shall not permit any of its Restricted Subsidiaries to issue any Disqualified Stock;
provided, however, that the Company and any of its Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, if the Company’s Consolidated Leverage Ratio at the time of incurrence of such
Indebtedness or the issuance of such Disqualified Stock, as the case may be, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom as if the same had occurred at the end of the most
recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been no greater than 3.25 to 1. 

  
 44 

 (b) The provisions of Section 4.09(a) hereof will not prohibit the
incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 

(1) (A) the incurrence by the Issuer or any Guarantor of Priority Lien Debt in an aggregate principal amount at any
time outstanding not to exceed the Priority Lien Cap and (B) the incurrence by the Issuer or any Guarantor of Junior Lien Debt in an aggregate principal amount at any time outstanding not to exceed the Junior Lien Cap;

transactions described in the Offering Circular and (B) Exchange Additional Notes issued under this Indenture following the date of the Second Supplemental Indenture) in an aggregate amount incurred pursuant to this clause (3) not to
exceed the Parity Lien Cap; 
 (4) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness represented by Capital Lease Obligations, mortgage financings, lease financings or purchase money obligations, in each case, incurred for the purpose of financing (whether or not incurred at the time of such purchase, design,
construction, installation, integration or improvement) all or any part of the purchase price or cost of design, construction, installation, integration or improvement of property, plant or equipment used in the business of the Company or any of its
Restricted Subsidiaries, or ownership rights with respect to indefeasible rights of use or minimum investment units (or similar ownership units) in domestic or transnational fiber optic cable or other transmission facilities, and, in each case,
including acquisitions by way of acquisitions of the Equity Interests of a Person that becomes a Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace,
defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed $30.0 million at any time outstanding; 
 (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace,

 45 

 (6) the incurrence by the Company or any of its Restricted Subsidiaries of

full in cash of all Obligations then due (and not merely outstanding under) with respect to the Notes, in the case of the Issuer, or the Note Guarantee, in the case of a Guarantor; and 

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a
Person other than the Company or a Restricted Subsidiary of the Company, and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company shall be deemed, in each
case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 

(7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted
Subsidiaries of shares of Disqualified Stock; provided, however, that: 
 (A) any subsequent issuance or
transfer of Equity Interests that results in any such Disqualified Stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and 

(B) any sale or other transfer of any such Disqualified Stock to a Person that is not either the Company or a Restricted
Subsidiary of the Company will be deemed, in each case, to constitute an issuance of such Disqualified Stock by such Restricted Subsidiary that was not permitted by this clause (7); 

(8) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of
business or incurred to hedge any interest rate risk on any fixed or floating rate Indebtedness that was permitted to be incurred under the first paragraph of this covenant or any clause under the definition of “Permitted Debt”;

 (9) (A) the Guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or
a Restricted Subsidiary of the Company to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this covenant; provided that if the Indebtedness being Guaranteed is subordinated to or pari
passu with the Notes, then the Guarantee must be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed; and (B) the Guarantee by Restricted Subsidiaries that are not Guarantors of Indebtedness
of Restricted Subsidiaries that are not Guarantors to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this covenant; 

  
 46 

 (10) the incurrence by the Company or any of the Restricted Subsidiaries of
Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, accommodation guarantees for the benefit of trade creditors, completion or performance guarantees, letters of credit, completion or
performance bonds and surety, appeal or judgment bonds or other similar obligations incurred in the ordinary course of business; 
 (11) the incurrence by the Company or any of the Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument

 (12) Indebtedness arising from agreements of the Company or a Restricted Subsidiary providing for indemnification, guarantees, earnouts, purchase price adjustments or similar obligations, in each case,

purpose of financing such acquisition;

Company or any Restricted Subsidiary owing to insurance companies or insurance premium financings, in each case, in the ordinary course of business; 
 (14) (A) Indebtedness of any Persons existing at the time such Persons become Subsidiary Guarantors or Restricted Subsidiaries or are merged with or into or consolidated with the Issuer or any Guarantor
or Restricted Subsidiary, or assumed in connection with an acquisition of property (including Equity Interests) by the Issuer or any Guarantor or Restricted Subsidiary and (B) other Indebtedness incurred in connection with an Asset Acquisition
by the Issuer or any Guarantor or Restricted Subsidiary, provided that such Indebtedness was in existence prior to the contemplation of such Persons becoming Subsidiary Guarantors or Restricted Subsidiaries or such merger or consolidation or
such acquisition of property or Asset Acquisition, provided further that the ratio of the aggregate principal amount of such Indebtedness incurred with respect to any such transaction to Consolidated EBITDA (for the most recent four-quarter
period for which financial information is available) attributable to the Person or property so acquired pursuant to such transaction (as determined in good faith by the Company) is 2.5 to 1.0 or less, and does not exceed (together with all Permitted
Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (14)) $20.0 million in the aggregate at any one time outstanding; 

  
 47

(c) The Company shall not incur, and shall not permit the Issuer or any other Guarantor to incur, any Indebtedness
(including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company, the Issuer or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and
the Note Guarantees on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of
being secured on junior priority basis or junior in right of distribution of collateral proceeds. 
 (d) For
purposes of determining compliance with this Section 4.09 and Section 4.12 hereof, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through
(16) of Section 4.09(b) hereof, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company shall be permitted (in its sole discretion) to classify such item of Indebtedness on the date of its incurrence, or later
reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant. Notwithstanding the foregoing, (x) all Priority Lien Debt will be deemed to have been incurred in reliance on the exception provided by
clause (1) of the definition of Permitted Debt and (y) all Parity Lien Debt outstanding on the date of this Indenture (including all Initial Notes) and all Parity Lien Debt represented by the Exchange Notes issued pursuant to the Exchange
Agreement will be deemed to have been incurred in reliance on the exception provided by clause (2) of the definition of Permitted Debt (provided, however, that such Parity Lien Debt under clause (y) of this sentence that is still
outstanding shall be taken into account in accordance with clause (1) of the definition of Parity Lien Cap in determining the amount of Parity Lien Debt that is available under clause (3) of the definition of Permitted Debt). The accrual
of interest or preferred stock or Disqualified Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of
preferred stock or Disqualified Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or
Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.09; provided, in each such case,

  
 48 

 
that the amount of any such accrual, accretion or payment is included in Consolidated Interest Expense of the Company as accrued. 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 utilized, calculated based on the relevant currency exchange rate in effect on
the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that (x) the U.S. dollar-equivalent principal amount of Existing Indebtedness
denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date of this Indenture, and (y) if such Indebtedness is incurred to renew, refund, refinance, replace, defease or discharge
other Indebtedness denominated in a foreign currency (or in a different currency from such Indebtedness so being incurred), and such renewal, refunding, refinancing, replacement, defeasance or discharge 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 renewal, refunding, refinancing, replacement, defeasance or discharge, such U.S. dollar-denominated restriction shall be
deemed not to have been exceeded so long as the principal amount of such new Indebtedness does not exceed (i) the outstanding or committed principal amount (whichever is higher) of such Indebtedness being renewed, refunded, refinanced,
replaced, defeased, or discharged plus (ii) the aggregate amount of accrued interest and fees, underwriting discounts, premiums and other costs and expenses incurred in connection with such renewal, refunding, refinancing,
replacement, defeasance or discharge. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to
be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 (e) The amount of any
Indebtedness outstanding as of any date will be: 
 (1) the accreted value of the Indebtedness (other than net
Hedging Obligations), in the case of any Indebtedness issued with original issue discount; 
 (2) the principal
amount of the Indebtedness (other than net Hedging Obligations), in the case of any other Indebtedness; 
 (3)
in respect of net Hedging Obligations, the termination value of the related Hedge Agreement that would be payable by the applicable Person as of such date; 
 (4) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: 

(A) the Fair Market Value of such assets at the date of determination; and 

(B) the amount of such Indebtedness of the other Person; and 

  
 49 

 (5) in respect of Disqualified Stock, an amount equal to the greater of its
voluntary or involuntary liquidation preference and its maximum fixed repurchase price, but excluding accrued dividends, if any.” 
 (dd) The Indenture shall be amended to restate in its entirety Section 4.10 as follows: 
 “Section 4.10 Asset Sales. 
 (a) The Company shall not,
and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) The Company
(or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or
Equity Interests issued or sold or otherwise disposed of; 
 (2) except in the case of a Permitted Asset Swap,
at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents; 
 For purposes of this Section 4.10(a)(2), each of the following will be deemed to be cash: 
 (A) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement that releases the Company or such Restricted Subsidiary from or indemnifies against
further liability; 
 (B) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as
a result of such Asset Sale, to the extent that the Company and its Restricted Subsidiaries are released from any guarantee of payment of the principal amount of such Indebtedness in connection with such Asset Sale; 

(C) any securities, Notes or other obligations received by the Company or any such Restricted Subsidiary from such
transferee that are converted by the Company or such Restricted Subsidiary into cash within one hundred twenty (120) days after such Asset Sale, to the extent of the cash received in that conversion; and 

(D) any stock or assets of the kind referred to in clause (3), (5) or (6) of paragraph (b) of this
Section 4.10; and 

  
 50 

 (3) subject to certain limitations, in the case of an Asset Sale that
constitutes a Sale of Collateral, the Company (or the applicable Restricted Subsidiary, as the case may be) promptly deposits the Net Proceeds therefrom promptly upon receipt thereof as Collateral in an account or accounts held by or under the
control of (for purposes of the Uniform Commercial Code) or otherwise subject to a perfected security interest in favor of the Collateral Trustee or its agent to secure all Secured Obligations. 

(b) Within three hundred sixty-five (365) days after the receipt of any Net Proceeds from an Asset Sale other than a
Sale of Collateral, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds, at its option: 
 (1) to repay, repurchase or redeem Priority Lien Obligations and, if the Priority Lien Obligations repaid are revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

 (2) to repay, repurchase or redeem Parity Lien Obligations; provided, that the Issuer offers to repay,
repurchase or redeem the Notes on a pro rata basis; 
 (3) to acquire all or substantially all of the assets of,
or any Equity Interests of, a Permitted Business (provided that in the case of any such acquisition of Equity Interests, after giving effect thereto, the Permitted Business is or becomes a Restricted Subsidiary of the Company); 

(4) to repay (A) Indebtedness (other than Secured Obligations) that is secured by a Permitted Lien on any assets
that were sold in such Asset Sale, or (B) obligations under the 13% Notes; 
 (5) to make a capital
expenditure; 
 (6) to acquire other assets that are not classified as current assets under GAAP and that are
used or useful in a Permitted Business; 
 (7) in the case of an Asset Sale by a Restricted Subsidiary that is
not a Guarantor, to repay, repurchase or redeem Indebtedness of the Company, the Issuer or any Restricted Subsidiary; or 
 (8) any combination of the foregoing clauses (1) through (7). 

(c) Within three hundred sixty-five (365) days after the receipt of any Net Proceeds from a Sale of Collateral, the
Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds, at its option: 
 (1) to purchase other assets that would constitute Collateral; 

(2) to acquire all or substantially all of the assets of, or any Equity Interests of, a Permitted Business
(provided that in the case of any such acquisition of Equity Interests, after giving effect thereto, the Permitted Business becomes a Guarantor or is merged into or consolidated with the Issuer or any Guarantor); 

  
 51 

 (3) to repay (A) Indebtedness (other than Secured Obligations) that is
secured by a Permitted Priority Lien on any Collateral that was sold in such Sale of Collateral, or (B) obligations under the 13% Notes; 
 (4) to make a capital expenditure with respect to assets that constitute Collateral; or 
 (5) any combination of the foregoing clauses (1) through (4). 

(d) In the case of clauses (3), (5) and (6) of paragraph (b) of this Section 4.10 and clauses (1),
(2) and (4) of paragraph (c) of this Section 4.10, the Company (or the applicable Restricted Subsidiary, as the case may be) will be deemed to have complied with its obligations in paragraphs (b) and (c) of this
Section 4.10 if it enters into a binding commitment to acquire such assets or Equity Interests prior to three hundred sixty-five (365) days after the receipt of the applicable Net Proceeds; provided that such binding commitment will be
subject only to customary conditions and such acquisition is completed within one hundred eighty (180) days following the expiration of the aforementioned three hundred sixty-five (365) day period. If the acquisition contemplated by such
binding commitment is not consummated on or before such one hundred eightieth (180th) day, and the Company (or the applicable Restricted Subsidiary, as the case may be) has not applied the applicable Net Proceeds for another purpose permitted
by the applicable paragraph (b) or (c) of this Section 4.10 on or before such one hundred eightieth (180th) day, such commitment shall be deemed not to have been a permitted application of Net Proceeds. 

(e) Pending the final application of any Net Proceeds of an Asset Sale, other than a Sale of Collateral, the Company (or
the applicable Restricted Subsidiary) may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 

(f) Any Net Proceeds from Asset Sales that are not applied or invested as provided in paragraph (b) (with respect to
Asset Sales other than Sales of Collateral) or paragraph (c) (with respect to a Sale of Collateral) of this Section 4.10 constitute “Excess Proceeds”. 

(g) When the aggregate amount of Excess Proceeds exceeds $15.0 million, within forty-five (45) days thereof, the
Issuer will make an offer (an “Asset Sale Offer”) to all Holders and all holders of other Parity Lien Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with
the proceeds of sales of assets, in accordance with Section 3.08 hereof, to purchase, prepay or redeem the maximum principal amount of Notes and such other Parity Lien Debt (plus all accrued interest on the Indebtedness and the
amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, 

  
 52 

 
prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest to the date
of purchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an
Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other Parity Lien Debt tendered into (or required to be prepaid or redeemed in
connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other Parity Lien Debt to be purchased on a pro rata basis, based on the amounts validly tendered (and not validly
withdrawn) or required to be prepaid or redeemed. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 (h) The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in
connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of Section 3.08 hereof or this Section 4.10, the
Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.08 hereof or this Section 4.10 by virtue of such compliance.”

(ii) The Indenture shall be amended to restate in its entirety Section 4.15 as follows: 

“Section 4.15 Offer to Repurchase Upon a Change of Control.

require the Issuer to repurchase all or any part of that Holder’s Notes (equal to $2,000 or an integral multiple of $1 in excess thereof) pursuant to this Section 4.15 (a “Change of Control Offer”). In the Change of
Control Offer, the Issuer will offer the Holders a purchase price in cash equal to 100% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase,

unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1 in excess thereof. 

  
 56 

 The Issuer will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions of any

Section 3.01 hereof, unless and until there is a default in payment of the applicable redemption price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control,
conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.”

Subsidiary designated as an Unrestricted Subsidiary shall be deemed to be an Investment made as of the time of the designation and shall reduce the amount available for Restricted Payments under
Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

of the Company as an Unrestricted Subsidiary shall be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate of the Company
certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the
Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted
if (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be
in existence following such designation.

Australian Net Income and Australian EBITDA of all Australian Subsidiaries are derived, in each case, for the four-quarter period immediately preceding such date and for which financial information is available, and (2) any Canadian Subsidiary
to be an Unrestricted Subsidiary other than Canadian Subsidiaries (together with all other Canadian Subsidiaries that constitute Unrestricted Subsidiaries) (i) that, as of the date of such designation, own less than 10% of the assets owned by
all Canadian Subsidiaries as of the end of the four-quarter period immediately preceding such date and for which financial information is available, and (ii) from which, as of the date of such designation, less than 10% of Canadian Net Income
and Canadian EBITDA of all Canadian Subsidiaries are derived, in each case, for the four-quarter period immediately preceding such date and for which financial information is available; provided that, in the case of each of clauses (1) and
(2) above, such Subsidiaries otherwise satisfy all of the criteria to be designated as “Unrestricted Subsidiaries” pursuant to this covenant.”

issuance of Initial Additional Notes or Exchange Additional Notes at an issue price equal to or greater than 100% of the principal amount thereof (for the avoidance of doubt, (A) this exception under clause (i) shall not apply to any term
or provision of the Initial Additional Notes or Exchange Additional Notes other than the issue price and (B) the issuance or incurrence of any Parity Lien Debt (other than the Initial Notes that were issued on the date on which this Indenture

4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17 and 4.18 and clauses (4), (5), (6) and (7) of Section 5.01(a) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are
satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof)
in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed 

  
 64 

 
outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuer and the Guarantors may omit to comply
with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any
such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and
such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, Sections 6.01(c) through 6.01(h) hereof will not constitute Events of Default.”

principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default
or Event of Default (other than a Default or Event of Default in the payment of the principal of, or premium or interest, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection
with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.”

 (zz) The Indenture shall be amended to restate in its entirety clause (g) of Section 9.02 as follows:

Section 9.02 as follows: 
 “In addition, (x) any amendment to,
or waiver of, the provisions of this Indenture or any Security Document that has the effect of releasing all or substantially all of the Collateral from the Liens securing the Notes will require the consent of the Holders of at least
66 2/3% in aggregate principal amount of the Notes then outstanding and (y) any amendment to, or waiver of, Section 4.19 of this Indenture shall require the consent of each Holder of the Exchange
Notes and each Holder of Exchange Additional Notes which were issued in exchange for Initial Notes following the consummation of the exchange of Initial Notes for Exchange Notes contemplated by the Exchange Agreement.” 

(bbb) The Indenture shall be amended to add the following sentence at the end of Section 10.01(a): 

“Notwithstanding anything herein to the contrary, each Note Guarantee shall guaranty equally and ratably all Parity Lien Debt under
the Initial Notes, the Exchange Notes and the Additional Notes.”

entirety Section 10.04 as follows:

Section 4.10 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge or amalgamate with or into (whether or not such Guarantor is the surviving Person) another Person, other
than the Company or another Guarantor, unless: 
 (a) immediately after giving effect to that transaction, no
Default or Event of Default exists; and 
 (b) either: 

(1) (A) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any
such consolidation or merger or amalgamation (the “Successor Guarantor”) assumes all the obligations of that Guarantor under its Note Guarantee, this Indenture, and the applicable Security Documents pursuant to a supplemental
indenture and appropriate Security Documents satisfactory to the Trustee, (B) the Successor Guarantor causes such amendments, supplements or other instruments to be executed, delivered, filed and recorded in such jurisdictions as may be
required by applicable law to preserve and protect the Liens under the applicable Security Documents on the Collateral owned by or transferred to the Successor Guarantor, together with such financing statements as may be required to perfect any
security interests in such Collateral which may be perfected by the filing of a financing statement under the Uniform Commercial Code of the relevant jurisdiction; (C) the Collateral owned by or transferred to the Successor

  
 66 

 
Guarantor shall: (i) continue to constitute Collateral under this Indenture and the applicable Security Documents, (ii) be subject to Liens in favor of the Collateral Trustee for the
benefit of the Holders and any other Parity Lien Indebtedness or Priority Lien Indebtedness and (iii) not be subject to any other Lien other than Permitted Liens; and (D) the property and assets of the Person which is merged or
consolidated with or into the Successor Guarantor, to the extent that they are property or assets of the types which would constitute Collateral under the applicable Security Documents, shall be treated as after-acquired property and the Successor
Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Lien of the applicable Security Documents in the manner and to the extent required under this Indenture and the Security
Documents; or 
 (2) the Net Proceeds of such sale or other disposition are applied in accordance with the
applicable provisions of this Indenture, including without limitation, Section 4.10 hereof. 
 In case of
any such consolidation, merger, amalgamation, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of the Note
Guarantee endorsed upon the applicable Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor
with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the applicable Notes issuable hereunder which theretofore shall
not have been signed by the Issuer and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance
with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. 
 Except as set forth in Articles 4 and 5 hereof, notwithstanding clauses (b)(1) and (2), nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor
with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.” 

(ddd) The Indenture shall be amended to restate in its entirety Sections 10.05(a) and Section 10.05(b) as follows: 

“(a) In the event of any sale or other disposition of all or substantially all of the assets of any Subsidiary
Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate
Section 4.10 hereof and is permitted by all of the Secured Debt Documents then the Person acquiring the property will be released and relieved of any obligations under the applicable Note Guarantee; 

  
 67 

 (b) in the event of any sale or other disposition of Capital Stock of any
Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.10 hereof and is
permitted by all of the Secured Debt Documents and the Subsidiary Guarantor ceases to be a Restricted Subsidiary of the Company as a result of the sale or other disposition, then such Subsidiary Guarantor will be released and relieved of any
obligations under its Note Guarantee; 
 provided, in both cases, that the Net Proceeds of such sale or other disposition
are applied in accordance with Section 4.10 hereof. Upon delivery by the Issuer to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Guarantor in accordance
with the provisions of this Indenture, including without limitation Section 4.10 hereof, the Trustee will execute any documents reasonably required in order to evidence the release of the Guarantor from its obligations under its Note
Guarantee.”

Section 4.10 hereof and is permitted by all of the other Security Documents, at the time of such sale, transfer or other disposition or to the extent of the interest sold, transferred or otherwise disposed of; provided that the
Collateral Trustee’s Liens upon the Collateral will not be released if the sale or disposition is subject to Section 5.01 hereof;” 
 (fff) The Indenture shall be amended to restate in its entirety Section 12.05(b) as follows:

Notes, the Exchange Notes and the Additional Notes; and 

  
 68 

 (2) all proceeds of all Parity Liens granted at any time by the Issuer or
any Guarantor will be allocated and distributed equally and ratably on account of the Parity Lien Debt (including without limitation, under the Initial Notes, the Exchange Notes and the Additional Notes) and other Parity Lien Obligations.”

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise
indicated. 
 (1) INTEREST. Primus Telecommunications Holding, Inc., a
Delaware corporation (the “Issuer”), promises to pay or cause to be paid interest on the principal amount of this Note at 10.00% per annum. The Issuer will pay interest, if any, semiannually in arrears on April 15 and
October 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date on which interest has been
paid or, if no interest has been paid, from the date of original issuance; provided that, if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue
from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be October 15, 2011. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law)
on overdue principal at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 

(2) METHOD OF PAYMENT. The Issuer will pay interest on
the Notes (except defaulted interest), if any, to the Persons who are registered Holders at the close of business on the April 1 or October 1 immediately preceding the Interest Payment Date, even if such Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the office or
agency of the Paying Agent and Registrar within the City and State of New York, or, at the option of the Issuer, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders;
provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium on, if any, and interest, if any, on all Global Notes and all other Notes the Holders of which will have provided
wire transfer instructions to the Issuer or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

(3) PAYING AGENT AND REGISTRAR.
Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change the Paying Agent or Registrar without prior notice to the Holders. The Issuer, the Company or any of its
Subsidiaries may act as Paying Agent or Registrar. 
 (4) INDENTURE AND
SECURITY DOCUMENTS. The Issuer issued the Notes under an Indenture, dated as of July 7, 2011 (as amended from time to time, the “Indenture”), by and among the Issuer, the guarantors party
thereto, and U.S. Bank National Association as Trustee and as Collateral Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of
such terms. To the extent any provision of this Note conflicts with the express provisions of the 

  
 A-1-2

 
Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured obligations of the Issuer. The Notes are secured by substantially all the assets of the Issuer
and the applicable Guarantors pursuant to and as further described in the Security Documents referred to in the Indenture. Subject to Sections 2.02, 2.13, 4.09 and 4.12 thereof, the Indenture does not limit the aggregate principal amount of Notes
that may be issued thereunder.

option, on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes issued under the Indenture, upon not less than thirty (30) nor more than sixty (60) days’ notice, with respect to this Note, at a
redemption price equal to 110.00% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the rights of Holders on the relevant record date to receive interest on
the relevant interest payment date) with the net cash proceeds of an Equity Offering by the Company; provided that: 
 (i) at least 65% of the original aggregate principal amount of the Notes issued under the Indenture (including the principal amount of any Additional Notes issued under the Indenture) remains outstanding

with respect to this Note, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest to the date of redemption, subject to the rights of
Holders on the relevant record date to receive interest due on the relevant interest payment date. The Issuer shall give the Trustee notice of the amount of the Applicable Premium promptly after the calculation thereof and the Trustee shall have no
responsibility for such calculation.

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless
otherwise indicated. 
 (1) INTEREST. Primus Telecommunications Holding,
Inc., a Delaware corporation (the “Issuer”), promises to pay or cause to be paid interest on the principal amount of this Note at 10.00% per annum. The Issuer will pay interest, if any, semiannually in arrears on April 15
and October 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date on which interest has
been paid or, if no interest has been paid, from the date of original issuance; provided that, if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be April 15, 2013. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy
Law) on overdue principal at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 
 Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Issuer will pay interest on the Notes (except defaulted interest), if any, to the Persons who are registered
Holders at the close of business on the April 1 or October 1 immediately preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the office or agency of the Paying Agent and Registrar within the City and State of New York,
or, at the option of the Issuer, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be
required with respect to principal of, premium on, if any, and interest, if any, on all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent. Such payment will be in
such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 (3) PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as
Paying Agent and Registrar. The Issuer may change the Paying Agent or Registrar without prior notice to the Holders. The Issuer, the Company or any of its Subsidiaries may act as Paying Agent or Registrar. 

(4) INDENTURE AND SECURITY DOCUMENTS. The Issuer issued
the Notes under an Indenture, dated as of July 7, 2011 (as amended from time to time, the “Indenture”), by and among the Issuer, the guarantors party thereto, and U.S. Bank National Association as Trustee and as Collateral
Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the
express provisions of the 

  
 A-2-2

 
Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured obligations of the Issuer. The Notes are secured by substantially all the assets of the Issuer
and the applicable Guarantors pursuant to and as further described in the Security Documents referred to in the Indenture. Subject to Sections 2.02, 2.13, 4.09 and 4.12 thereof, the Indenture does not limit the aggregate principal amount of Notes
that may be issued thereunder.

Note, at a redemption price equal to 100.00% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the rights of Holders on the relevant record date to receive
interest on the relevant interest payment date) with the net cash proceeds of an Equity Offering by the Company; provided that: 
 (i) at least 65% of the original aggregate principal amount of the Notes issued under the Indenture (including the principal amount of any Additional Notes issued under the Indenture) remains outstanding

Articles 8 or 11 thereof. Notes in denominations larger than $2,000.00 may be redeemed or purchased in part but only in multiples of $1.00; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of
Notes held by such Holder shall be redeemed or purchased. On or after the redemption dates, interest ceases to accrue on the Notes or portions thereof cancelled for redemption.
