NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except per share amounts)

(Unaudited)

Note 1.    Basis of Presentation and Significant Accounting Policies

Nature of Operations

Vonage Holdings Corp. (“Vonage”, “Company”, “we”, “our”, “us”) is incorporated as a Delaware corporation. We are a leading provider of low-cost communications services connecting people through cloud-connected devices worldwide. Customers in the United States represented 93% of our subscriber lines for our broadband telephone replacement services at June 30, 2013, with the balance primarily in Canada and the United Kingdom.

Unaudited Interim Financial Information

The accompanying unaudited interim consolidated financial statements and information have been prepared in accordance with accounting principles generally accepted in the United States and in accordance with the instructions for Form 10-Q. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, these financial statements contain all normal and recurring adjustments considered necessary to present fairly the financial position, results of operations, cash flows, and statement of stockholders’ equity for the periods presented. The results for the three and six months ended June 30, 2013 are not necessarily indicative of the results to be expected for the full year.

These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2012 filed with the Securities and Exchange Commission on February 13, 2013.

Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of Vonage and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.

On an ongoing basis, we evaluate our estimates, including the following:

• the useful lives of property and equipment, software costs, and intangible assets;

• assumptions used for the purpose of determining share-based compensation using the Black-Scholes option pricing model (“Model”), and various other assumptions that we believe to be reasonable; the key inputs for this Model are our stock price at valuation date, exercise price, the dividend yield, risk-free interest rate, life in years, and historical volatility of our common stock; and

• assumptions used in determining the need for, and amount of, a valuation allowance on net deferred tax assets.

We base our estimates on historical experience, available market information, appropriate valuation methodologies, and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.

Revenue Recognition

Revenues consist of telephony services revenues and customer equipment (which enables our telephony services) and shipping revenues. The point in time at which revenues are recognized is determined in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104, Revenue Recognition, and Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition.

VONAGE HOLDINGS CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except per share amounts)

(Unaudited)

At the time a customer signs up for our telephony services, there are the following deliverables:

• Providing equipment, if any, to the customer that enables our telephony services; and

• Providing telephony services.

The equipment is provided free of charge to our customers and in most instances there are no activation fees collected at sign-up. We record the fees collected for shipping the equipment to the customer, if any, as shipping and handling revenue at the time of shipment.

Telephony Services Revenue

Substantially all of our revenues are telephony services revenues, which are derived primarily from monthly subscription fees that customers are charged under our service plans. We also derive telephony services revenues from per minute fees for international calls if not covered under a plan, including applications for mobile devices and other stand-alone products, and for any calling minutes in excess of a customer’s monthly plan limits. Monthly subscription fees are automatically charged to customers’ credit cards, debit cards or electronic check payments ("ECP"), in advance and are recognized over the following month when services are provided. Revenues generated from international calls and from customers exceeding allocated call minutes under limited minute plans are recognized as services are provided, that is, as minutes are used, and are billed to a customer’s credit cards, debit cards or ECP in arrears. As a result of our multiple billing cycles each month, we estimate the amount of revenues earned from international calls and from customers exceeding allocated call minutes under limited minute plans but not billed from the end of each billing cycle to the end of each reporting period and record these amounts as accounts receivable. These estimates are based primarily upon historical minutes and have been consistent with our actual results.

We also provide rebates to customers who purchase their customer equipment from retailers and satisfy minimum service period requirements. These rebates in excess of activation fees are recorded as a reduction of revenues over the service period based upon the estimated number of customers that will ultimately earn and claim the rebates.

In the United States, we charge regulatory, compliance, E-911, and intellectual property-related fees on a monthly basis to defray costs, and to cover taxes that we are charged by the suppliers of telecommunications services. In addition, we charge customers Federal Universal Service Fund (“USF”) fees. We recognize revenue on a gross basis for USF and related fees. We record these fees as revenue when billed. All other taxes are recorded on a net basis.

Customer Equipment and Shipping Revenue

Customer equipment and shipping revenues, comprising an incidental portion of our revenue, derives from revenues from sales of customer equipment to wholesalers or directly to customers for replacement devices, or for upgrading their device at the time of customer sign-up for which we charge an additional fee. In addition, customer equipment and shipping revenues include the fees that customers are charged for shipping their customer equipment to them. Customer equipment and shipping revenues include sales to our retailers, who subsequently resell this customer equipment to customers. Revenues are reduced for payments to retailers and rebates to customers who purchased their customer equipment through these retailers, to the extent of customer equipment and shipping revenues.

Direct Cost of Telephony Services

Direct cost of telephony services consists primarily of direct costs that we pay to third parties in order to provide telephony services. These costs include access and interconnection charges that we pay to other telephone companies to terminate domestic and international phone calls on the public switched telephone network. In addition, these costs include the cost to lease phone numbers, to co-locate in other telephone companies’ facilities, to provide enhanced emergency dialing capabilities to transmit 911 calls, and to provide local number portability. These costs also include taxes that we pay on telecommunications services from our suppliers or are imposed by government agencies such as Federal USF and royalties for use of third parties’ intellectual property. These costs do not include indirect costs such as depreciation and amortization, payroll, and facilities costs. Our presentation of direct cost of telephony services may not be comparable to other similar companies.

Direct Cost of Goods Sold

Direct cost of goods sold consists primarily of costs that we incur when a customer signs up for our service. These costs include the cost of customer equipment for customers who subscribe through the direct sales channel in excess of activation fees.

(Unaudited)

In addition, these costs include the amortization of deferred customer equipment, the cost of shipping and handling for customer equipment, the installation manual that accompanies the customer equipment, and the cost of certain promotions.

Development Expenses

Costs for research, including predevelopment efforts prior to establishing technological feasibility of software expected to be marketed, are expensed as incurred. Development costs are capitalized when technological feasibility has been established and anticipated future revenues support the recoverability of the capitalized amounts. Capitalization stops when the product is available for general release to customers. Due to the short time period between achieving technological feasibility and product release and the insignificant amount of costs incurred during such periods, we have not capitalized any software development, and have expensed these costs as incurred. These costs are included in selling, general and administrative expense.

Cash and Cash Equivalents

We maintain cash with several investment grade financial institutions. Highly liquid investments, which are readily convertible into cash, with original maturities of three months or less, are recorded as cash equivalents.

Certain Risks and Concentrations

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash equivalents and accounts receivable. They are subject to fluctuations in both market value and yield based upon changes in market conditions, including interest rates, liquidity, general economic conditions, and conditions specific to the issuers. Accounts receivable are typically unsecured and are derived from revenues earned from customers primarily located in the United States. A portion of our accounts receivable represents the timing difference between when a customer’s credit card is billed and the subsequent settlement of that transaction with our credit card processors. This timing difference is generally three days for substantially all of our credit card receivables. We have never experienced any accounts receivable write-offs due to this timing difference. In addition, we collect subscription fees in advance, minimizing our accounts receivable and bad debt exposure. If a customer’s credit card, debit card or ECP is declined, we generally suspend international calling capabilities as well as their ability to incur domestic usage charges in excess of their plan minutes. If the customer’s credit card, debit card or ECP could not be successfully processed during three billing cycles (i.e., the current and two subsequent monthly billing cycles), we terminate the account. In addition, we automatically charge any per minute fees to our customers’ credit card, debit card or ECP monthly in arrears. To further mitigate our bad debt exposure, a customer’s credit card, debit card or ECP will be charged in advance of their monthly billing if their international calling or overage charges exceed a certain dollar threshold.

Inventory

Inventory consists of the cost of customer equipment and is stated at the lower of cost or market, with cost determined using the average cost method. We provide an inventory allowance for customer equipment that has been returned by customers but may not be able to be re-issued to new customers or returned to the manufacturer for credit.

Property and Equipment

Property and equipment includes acquired assets and those accounted for under capital leases and consist principally of network equipment and computer hardware, furniture, software, and leasehold improvements. In addition, the lease of our corporate headquarters has been accounted for as a capital lease and is included in property and equipment. Network equipment and computer hardware and furniture are stated at cost with depreciation provided using the straight-line method over the estimated useful lives of the related assets, which range from three to five years. Leasehold improvements are amortized over their estimated useful life of the related assets or the life of the lease, whichever is shorter. The cost of renewals and substantial improvements is capitalized while the cost of maintenance and repairs is charged to operating expenses as incurred.

Our network equipment and computer hardware, which consists of routers, gateways, and servers that enable our telephony services, is subject to technological risks and rapid market changes due to new products and services and changing customer demand. These changes may result in future adjustments to the estimated useful lives or the carrying value of these assets, or both.

Software Costs

We capitalize certain costs, such as purchased software and internally developed software that we use for customer acquisition and customer care automation tools, in accordance with FASB ASC 350-40, “Internal-Use Software”. Computer software is stated at cost less accumulated amortization and the estimated useful life is two to five years.

As previously disclosed, we experienced delays and incremental costs during the course of the development and implementation of a new billing and ordering system by Amdocs Software Systems Limited and Amdocs, Inc. (collectively, "Amdocs") and the transition of customers to the system. We conducted discussions with Amdocs to resolve the issues associated with the billing and ordering system. Based on these discussions, and after our consideration of the progress made improving our overall IT infrastructure, the incremental time and costs to develop and implement the Amdocs system, as well as the expected reduction in capital expenditures, in June 2012 we and Amdocs determined that terminating the program was in the best interest of both parties. On July 30, 2012, we entered into a Settlement Agreement with Amdocs terminating the related license agreement. As a result, we wrote off our investment in the system of $25,262, net of settlement amounts to us, in the second quarter of 2012. This charge is recorded as loss from abandonment of software assets in the statement of operations.

Intangible Assets

Intangible assets acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.

Patents and Patent Licenses

Patent rights acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.

Long-Lived Assets

We evaluate impairment losses on long-lived assets used in operations when events and changes in circumstances indicate that the assets might be impaired. If our review indicates that the carrying value of an asset will not be recoverable, based on a comparison of the carrying value of the asset to the undiscounted future cash flows, the impairment will be measured by comparing the carrying value of the asset to its fair value. Fair value will be determined based on quoted market values, discounted cash flows or appraisals. Impairments of long-lived assets used in operations are recorded in the statement of operations as part of depreciation expense.

Debt Related Costs

Costs incurred in raising debt are deferred and amortized as interest expense using the effective interest method over the life of the debt.

Derivatives

We do not hold or issue derivative instruments for trading purposes. However, in accordance with FASB ASC 815, “Derivatives and Hedging” (“FASB ASC 815”), we review our contractual obligations to determine whether there are terms that possess the characteristics of derivative financial instruments that must be accounted for separately from the financial instrument in which they are embedded. We would recognize these features, if any, as liabilities in our consolidated balance sheet at fair value each period and would recognize any change in the fair value in our statement of operations in the period of change. We would estimate the fair value of these liabilities using available market information and appropriate valuation methodologies.

Income Taxes

We recognize deferred tax assets and liabilities at enacted income tax rates for the temporary differences between the financial reporting bases and the tax bases of our assets and liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. Our net deferred tax assets primarily consist of net operating loss carry forwards (“NOLs”). We are required to record a valuation allowance against our net deferred tax assets to the extent we conclude that it is more likely than not that taxable income generated in the future will be insufficient to utilize the future income tax benefit from our net deferred tax assets (namely, the NOLs) prior to expiration. In the fourth quarter of 2011, we concluded that it was more likely than not that taxable income in the future would be sufficient to utilize a significant portion of the future

income tax benefit from our net deferred tax assets (namely, the NOLs) prior to expiration and we released $325,601 of the valuation allowance. We periodically review this conclusion, which requires significant management judgment. In the future, if available evidence changes our conclusions, we will make an adjustment to the related valuation allowance and income tax expense at that time. The June 30, 2012 effective rate is less than the federal statutory rate due, in part, to our Canadian operations and certain discrete period items, which primarily consisted of adjustments related to stock compensation, including a non-cash deferred tax adjustment totaling $4,077 for certain stock compensation previously considered nondeductible under Section 162(m) of the Internal Revenue Code. The 2013 estimated annual effective tax rate is expected to approximate 41%, but may fluctuate due to the timing of other discrete period transactions.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution.

We have not had any unrecognized tax benefits. We recognize interest and penalties accrued related to unrecognized tax benefits as components of our income tax provision. We have not had any interest and penalties accrued related to unrecognized tax benefits.

Fair Value of Financial Instruments

Effective January 1, 2008, we adopted FASB ASC 820-10-25, “Fair Value Measurements and Disclosures”. This standard establishes a framework for measuring fair value and expands disclosure about fair value measurements. We did not elect fair value accounting for any assets and liabilities allowed by FASB ASC 825, “Financial Instruments”.

FASB ASC 820-10 defines fair value as the amount that would be received for an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC 820-10 also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. FASB ASC 820-10 describes the following three levels of inputs that may be used:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets and liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data.

Level 3: Unobservable inputs when there is little or no market data available, thereby requiring an entity to develop its own assumptions. The fair value hierarchy gives the lowest priority to Level 3 inputs.

Fair Value of Other Financial Instruments

The carrying amounts of our financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, approximate fair value because of their short maturities. The carrying amounts of our capital leases approximate fair value of these obligations based upon management’s best estimates of interest rates that would be available for similar debt obligations at June 30, 2013 and December 31, 2012. We believe the fair value of our debt at June 30, 2013 was approximately the same as its carrying amount as market conditions, including available interest rates, credit spread relative to our credit rating, and illiquidity, remain relatively unchanged from the issuance date of our debt on February 11, 2013 for a similar debt instrument.

Foreign Currency

Generally, the functional currency of our non-United States subsidiaries is the local currency. The financial statements of these subsidiaries are translated to United States dollars using month-end rates of exchange for assets and liabilities, and average rates of exchange for revenues, costs, and expenses. Translation gains and losses are deferred and recorded in accumulated other comprehensive income as a component of stockholders’ equity.

Share-Based Compensation

We account for share-based compensation in accordance with FASB ASC 718, “Compensation-Stock Compensation”. Under the fair value recognition provisions of this pronouncement, share-based compensation cost is measured at the grant date based on the fair value of the award, reduced as appropriate based on estimated forfeitures, and is recognized as expense over the applicable vesting period of the stock award using the accelerated method. The excess tax benefit associated with stock compensation deductions have not been recorded in additional paid-in capital. When evaluating whether an excess tax benefit has been realized, share based compensation deductions are not considered realized until NOLs are no longer sufficient to offset taxable income. Such excess tax benefits will be recorded when realized.

Earnings per Share

Net income per share has been computed according to FASB ASC 260, “Earnings per Share”, which requires a dual presentation of basic and diluted earnings per share (“EPS”). Basic EPS represents net income divided by the weighted average number of common shares outstanding during a reporting period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock, including stock options and restricted stock units under our 2001 Stock Incentive Plan and 2006 Incentive Plan, were exercised or converted into common stock. The dilutive effect of outstanding stock options and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method. In applying the treasury stock method for stock-based compensation arrangements, the assumed proceeds are computed as the sum of the amount the employee must pay upon exercise and the amounts of average unrecognized compensation cost attributed to future services.

The following table sets forth the computation for basic and diluted net income per share for the three and six months ended June 30, 2013 and 2012:

July 2011 Financing

On July 29, 2011, we entered into a credit agreement (the "2011 Credit Facility") consisting of an $85,000 senior secured term loan and a $35,000 revolving credit facility. The co-borrowers under the 2011 Credit Facility were our wholly owned subsidiary, Vonage America Inc., and us. Obligations under the 2011 Credit Facility were guaranteed, fully and unconditionally, by our other United States subsidiaries and were secured by substantially all of the assets of each borrower and each of the guarantors.

Use of Proceeds

We used $100,000 of the net available proceeds of the 2011 Credit Facility, plus $31,000 of cash on hand, to retire all of the debt under our prior credit facility entered into in 2010, including a $1,000 prepayment fee to holders of that credit facility. We also incurred $2,697 of fees in connection with the 2011 Credit Facility, which was amortized to interest expense over the life of the debt using the effective interest method.

2013 Financing

On February 11, 2013 we entered into Amendment No. 1 to the 2011 Credit Agreement (as further amended by Amendment No. 2 to our 2011 Credit Facility, the "2013 Credit Facility"). The 2013 Credit Facility consists of a $70,000 senior secured term loan and a $75,000 revolving credit facility. The co-borrowers under the 2013 Credit Facility are our wholly owned subsidiary, Vonage America Inc., and us. Obligations under the 2013 Credit Facility are guaranteed, fully and unconditionally, by our other United States subsidiaries and are secured by substantially all of the assets of each borrower and each of the guarantors. On July 26, 2013 we entered into Amendment No. 2 to our 2011 Credit Agreement, which amends our financial covenant related to our consolidated fixed charge coverage ratio by increasing the amount of restricted payments excluded from such calculation from $50,000 to $80,000.

Use of Proceeds

The net proceeds received of $27,500 from the senior secured term loan and the undrawn revolving credit facility under the 2013 Credit Facility will be used for general corporate purposes. We also incurred $2,009 of fees in connection with the 2013 Credit Facility, which is amortized, along with the unamortized fees of $670 in connection with the 2011 Credit Facility, to interest expense over the life of the debt using the effective interest method.

2013 Credit Facility Terms

The following description summarizes the material terms of the 2013 Credit Facility:

The loans under the 2013 Credit Facility mature in February 2016. Principal amounts under the 2013 Credit Facility are repayable in quarterly installments of $5,833 per quarter for the senior secured term loan. The unused portion of our revolving credit facility incurs a 0.45% commitment fee.

Outstanding amounts under the 2013 Credit Facility, at our option, will bear interest at:

• LIBOR (applicable to one-, two-, three- or six-month periods) plus an applicable margin equal to 3.125% if our consolidated leverage ratio is less than 0.75 to 1.00, 3.375% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 3.625% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last day of each relevant interest period or, if the interest period is longer than 3 months, each day that is three months after the first day of the interest period, or

• the base rate determined by reference to the highest of (a) the federal funds effective rate from time to time plus 0.50%, (b) the prime rate of JPMorgan Chase Bank, N.A., and (c) the LIBOR rate applicable to one month interest periods plus 1.00%, plus an applicable margin equal to 2.125% if our consolidated leverage ratio is less than 0.75 to 1.00, 2.275% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 2.625% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last business day of each March, June, September, and December and the maturity date of the 2013 Credit Facility.

The 2013 Credit Facility provides greater flexibility to us in funding acquisitions and restricted payments, such as stock buybacks, than the 2011 Credit Facility.

We may prepay the 2013 Credit Facility at our option at any time without premium or penalty. The 2013 Credit Facility is subject to mandatory prepayments in amounts equal to:

• 100% of the net cash proceeds from any non-ordinary course sale or other disposition of our property and assets for consideration in excess of a certain amount subject to customary reinvestment provisions and certain other exceptions and

• 100% of the net cash proceeds received in connection with other non-ordinary course transactions, including insurance proceeds not otherwise applied to the relevant insurance loss.

Subject to certain restrictions and exceptions, the 2013 Credit Facility permits us to obtain one or more incremental term loans and/or revolving credit facilities in an aggregate principal amount of up to $60,000 plus an amount equal to repayments of the senior secured term loan upon providing documentation reasonably satisfactory to the administrative agent, without the consent of the existing lenders under the 2013 Credit Facility. The 2013 Credit Facility includes customary representations and warranties and affirmative covenants of the borrowers. In addition, the 2013 Credit Facility contains customary negative covenants, including, among other things, restrictions on the ability of us and our subsidiaries to consolidate or merge, create liens, incur additional indebtedness, dispose of assets, consummate acquisitions, make investments, and pay dividends and other distributions. We must also comply with the following financial covenants:

• a consolidated leverage ratio of no greater than 2.00 to 1.00;

• a consolidated fixed coverage charge ratio of no less than 1.75 to 1.00 subject to adjustment to exclude up to $80,000 in specified restricted payments;

• minimum cash of $25,000 including the unused portion of the revolving credit facility or $35,000 in the event of certain specified corporate actions; and

• maximum capital expenditures not to exceed $55,000 during any fiscal year, provided that the unused amount of any permitted capital expenditures in any fiscal year may be carried forward to the next following fiscal year; in addition, annual excess cash flow up to $8,000 increases permitted capital expenditures.

As of June 30, 2013, we were in compliance with all covenants, including financial covenants, for the 2013 Credit Facility.

The 2013 Credit Facility contains customary events of default that may permit acceleration of the debt. During the continuance of a payment default, interest will accrue at a default interest rate of 2% above the interest rate which would otherwise be applicable, in the case of loans, and at a rate equal to the rate applicable to base rate loans plus 2%, in the case of all other amounts.

Note 5.    Common Stock

Net Operating Loss Rights Agreement

On June 7, 2012, we entered into a Tax Benefits Preservation Plan ("Preservation Plan") designed to preserve stockholder value and tax assets. Our ability to use our tax attributes to offset tax on U.S. taxable income would be substantially limited if there were an "ownership change" as defined under Section 382 of the U.S. Internal Revenue Code. In general, an ownership change would occur if one or more "5-percent shareholders," as defined under Section 382, collectively increase their ownership in us by more than 50 percent over a rolling three-year period.

In connection with the adoption of the Preservation Plan, our board of directors declared a dividend of one preferred share purchase right for each outstanding share of the Company’s common stock. The preferred share purchase rights were distributed to stockholders of record as of June 18, 2012, as well as to holders of the Company's common stock issued after that date, but will only be activated if certain triggering events under the Preservation Plan occur.

Under the Preservation Plan, preferred share purchase rights will work to impose significant dilution upon any person or group which acquires beneficial ownership of 4.9% or more of the outstanding common stock, without the approval of our board of directors, from and after June 7, 2012. Stockholders that own 4.9% or more of the outstanding common stock as of the opening of business on June 7, 2012, will not trigger the preferred share purchase rights so long as they do not (i) acquire additional shares of common stock or (ii) fall under 4.9% ownership of common stock and then re-acquire shares that in the aggregate equal 4.9% or more of the common stock.

The Preservation Plan was set to expire no later than the close of business June 7, 2013, unless extended by our board of directors. On April 4, 2013, after consultation with our advisors, our board of directors determined to extend the Preservation Plan through June 7, 2015, subject to ratification of the extension by stockholders at the Vonage 2013 annual meeting of stockholders. On June 6, 2013, at the Vonage 2013 annual meeting of stockholders, stockholders ratified the extension of the Preservation Plan through June 7, 2015.

Common Stock Repurchases

On July 25, 2012, our board of directors authorized a program to repurchase up to $50,000 of Vonage common stock (the "$50,000 repurchase program") through December 31, 2013. The specific timing and amount of repurchases would vary based on available capital resources and other financial and operational performance, market conditions, securities law limitations, and other factors. The repurchases would be made using our cash resources.

We repurchased the following shares of common stock with cash resources under the $50,000 repurchase program during the three and six months ended June 30, 2013:

	Three Months Ended		Six Months Ended
	June 30,		June 30,
	2013		2013
Shares of common stock repurchased	—		2,189
Value of common stock repurchased	$	—	$	5,374

On February 7, 2013, our board of directors discontinued the remainder of our existing $50,000 repurchase program effective at the close of business on February 12, 2013 with $16,682 of availability remaining, and authorized a new program to repurchase up to $100,000 of Vonage common stock (the "$100,000 repurchase program") by December 31, 2014. The specific timing and amount of repurchases will vary based on available capital resources and other financial and operational performance, market conditions, securities law limitations, and other factors. The repurchases will be made using our cash resources. The $100,000 repurchase program may be suspended or discontinued at any time without prior notice.

20

We repurchased the following shares of common stock with cash resources under the $100,000 repurchase program during the three and six months ended June 30, 2013*:

	Three Months Ended		Six Months Ended
	June 30,		June 30,
	2013		2013
Shares of common stock repurchased	4,756		8,795
Value of common stock repurchased	$	13,451	$	24,458

* including 220 shares, or $625, of common stock repurchases settled in July 2013; excluding commission of $4.

As of June 30, 2013, approximately $75,542 remained of our $100,000 repurchase program. The repurchase program expires on December 31, 2014 but may be suspended or discontinued at any time without notice.

In any period under either repurchase program, cash used in financing activities related to common stock repurchases may differ from the comparable change in stockholders' equity, reflecting timing differences between the recognition of share repurchase transactions and their settlement for cash.

Stock Option Cancellation

As part of our strategy to build shareholder value and to facilitate our goal of reducing the number of shares of common stock outstanding, on February 19, 2013, we entered into an agreement with our Chief Executive Officer to cancel a total of 4,500 of his vested stock options for $5,463. The payment reflects a discount, in favor of the Company, from the closing price of the common stock on the New York Stock Exchange on February 19, 2013.

Litigation

IP Matters

Bear Creek Technologies, Inc. On February 22, 2011, Bear Creek Technologies, Inc. (“Bear Creek”) filed a lawsuit against Vonage Holdings Corp., Vonage America, Inc., and Vonage Marketing LLC in the United States District Court for the Eastern District of Virginia (Norfolk Division) alleging that Vonage's products and services are covered by United States Patent No. 7,889,722, entitled “System for Interconnecting Standard Telephony Communications Equipment to Internet Protocol Networks” (the “722 Patent”). The suit also named numerous other defendants, including Verizon Communications, Inc., Comcast Corporation, Time-Warner Cable, Inc., AT&T, Inc., and T-Mobile USA Inc. On August 17, 2011, the Court dismissed Bear Creek's case against the Vonage entities, as well as all the other defendants, except for one defendant. Later, on August 17, 2011, Bear Creek re-filed its complaint concerning the '722 Patent in the United States District Court for the District of Delaware against the same Vonage entities. In its Delaware complaint, Bear Creek alleges that Vonage is infringing one or more claims of the '722 Patent. In addition, Bear Creek alleges that Vonage is contributing to and inducing infringement of one or more claims of the '722 Patent. On September 28, 2011, Vonage filed a motion to dismiss Bear Creek's claims for induced, contributory, and willful infringement, which was denied on September 27, 2012. On January 25, 2012, Bear Creek filed a motion with the United States Judicial Panel on Multidistrict Litigation seeking to transfer and consolidate its litigation against Vonage with thirteen separate actions Bear Creek filed in the U.S. District Courts for Delaware and the Eastern District of Virginia. On May 2, 2012, the Multidistrict Litigation Panel granted Bear Creek's motion and ordered the coordination or consolidation for pretrial proceedings of all fourteen actions in the U.S. District Court for the District of Delaware. On October 11, 2012, Vonage filed an answer to Bear Creek's complaint, including counterclaims of non-infringement and invalidity of the '722 patent. On November 5, 2012, Bear Creek filed an answer to Vonage's counterclaims. On March 1, 2013, several defendants including Vonage moved the Court to stay the case pending resolution of the reexamination of the '722 patent requested by Cisco Systems, Inc. (“Cisco”) as described below; the motion was granted on July 17, 2013, and the case is now stayed pending the resolution of the reexamination.

On March 8, 2012, a third-party requested the United States Patent and Trademark Office ("USPTO") to reexamine the validity of the asserted '722 Patent.  The USPTO granted the request on April 26, 2012, and subsequently issued an initial Office Action rejecting all of the '722 Patent claims. After reconsideration based on statements made by the patentee, the USPTO on September 19, 2012, reversed its initial rejection, and confirmed all claims as patentable over the references cited in the reexamination request. A second request for reexamination of the '722 Patent was filed on September 12, 2012, by Cisco, challenging the validity of the '722 Patent. Cisco's request was granted by the USPTO on November 28, 2012.  On March 26, 2013, the USPTO issued an Office Action rejecting all claims of the '722 patent as invalid. Bear Creek responded to the Office Action on May 28,

2013, requesting withdrawal of the USPTO's rejection.  Cisco responded to Bear Creek's submission on June 26, 2013. A third request for reexamination of the '722 Patent was filed on September 14, 2012, and the USPTO denied this request on December 6, 2012.

OpinionLab, Inc. On July 18, 2012, OpinionLab, Inc. (“OpinionLab”) filed a lawsuit against IPerceptions, Inc. and IPerceptions US, Inc. (collectively, “IPerceptions”) in the United States District Court for the District of Northern Illinois (Eastern Division) alleging claims of patent infringement, breach of contract, misappropriation of trade secrets, and tortious interference with business expectancy. On August 16, 2012, OpinionLab filed an amended complaint, adding Vonage Marketing LLC and Vonage Holdings Corp. as defendants, and alleging that Vonage's products and services are covered by United States Patent Nos. 6,421,724, 6,606,581, 6,928,392, 7,085,820, 7,370,285, 8,024,668, and 8,041,805. OpinionLab alleged direct, indirect and willful infringement by Vonage. IPerceptions, the supplier to Vonage of the accused product in this lawsuit, has agreed to fully defend and indemnify Vonage in this lawsuit. On September 11, 2012, IPerceptions and Vonage each moved to dismiss OpinionLab's indirect and willful patent infringement claims. The motions were denied on November 8, 2012. Vonage answered the complaint on December 7, 2012. On July 11, 2013, the Court issued an order setting the case schedule.

RPost Holdings, Inc. On August 24, 2012, RPost Holdings, Inc., RPost Communications Limited, and RMail Limited (collectively, “RPost”) filed a lawsuit against StrongMail Systems, Inc. (“StrongMail”) in the United States District Court for the Eastern District of Texas (Marshall Division) alleging that StrongMail's products and services, including its electronic mail marketing services, are covered by United States Patent Nos. 8,224,913, 8,209,389, 8,161,104, 7,966,372, and 6,182,219. On January 16, 2013, StrongMail moved the Court to transfer the venue of the lawsuit to the Northern District of California. That motion is now fully-briefed and pending before the Court. On February 11, 2013, RPost filed an amended complaint, adding 27 new defendants, including Vonage America Inc. RPost's amended complaint alleges willful infringement of the RPost patents by Vonage and each of the other new defendants because they are customers of StrongMail. RPost first served Vonage with the lawsuit on March 8, 2013. StrongMail has agreed to fully defend and indemnify Vonage in this lawsuit. Vonage answered the complaint on May 7, 2013.

From time to time, in addition to those identified above, we are subject to legal proceedings, claims, investigations, and proceedings in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. From time to time we receive letters or other communications from third parties inviting us to obtain patent licenses that might be relevant to our business or alleging that our services infringe upon third party patents or other intellectual property. In accordance with generally accepted accounting principles, we make a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss or range of loss can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. We believe that we have valid defenses with respect to the legal matters pending against us and are vigorously defending these matters. Given the uncertainty surrounding litigation and our inability to assess the likelihood of a favorable or unfavorable outcome in the above noted matters and our inability to reasonably estimate the amount of loss or range of loss, it is possible that the resolution of one or more of these matters could have a material adverse effect on our consolidated financial position, cash flows or results of operations.

Regulation

Telephony services are subject to a broad spectrum of state and federal regulations. Because of the uncertainty over whether Voice over Internet Protocol (“VoIP”) should be treated as a telecommunications or information service, we have been involved in a substantial amount of state and federal regulatory activity. Implementation and interpretation of the existing laws and regulations is ongoing and is subject to litigation by various federal and state agencies and courts. Due to the uncertainty over the regulatory classification of VoIP service, there can be no assurance that we will not be subject to new regulations or existing regulations under new interpretations, and that such change would not introduce material additional costs to our business.

Federal - Net Neutrality

Clear and enforceable net neutrality rules would make it more difficult for broadband Internet service providers to block or discriminate against Vonage service. Also explicitly applying net neutrality rules to wireless broadband Internet service could create greater opportunities for VoIP applications that run on wireless broadband Internet service. In October 2009, the FCC proposed the adoption of enforceable net neutrality rules for both wired and wireless broadband Internet service providers. The proposed rules would prohibit wired and wireless broadband Internet service providers from blocking or hindering lawful content, applications, or services and from unreasonably discriminating when transmitting lawful network traffic. In addition, broadband Internet service providers would have to publicly disclose certain information about their network management practices. In

(Unaudited)

December 2010, the FCC adopted enforceable net neutrality rules based on its October 2009 proposal. All of the proposed rules in the October 2009 proposal applied to wired broadband Internet providers. The FCC applied some but not all of the proposed rules to wireless broadband service. Wireless broadband Internet services providers are prohibited from blocking or hindering voice or video applications that compete with the broadband Internet service provider's voice or video services. Wireless providers are also subject to transparency requirements, but they are not subject to the prohibition on unreasonable discrimination that applies to wired broadband Internet services providers. Final rules were filed in the Federal Register in September 2011. Shortly thereafter, a number of parties filed appeals of the rules in various federal circuit courts; some alleging that the FCC lacks authority to apply net neutrality rules to broadband service providers and some alleging that the rules did not go far enough. The D.C. Circuit Court of Appeals was selected by lottery to decide the appeals and the appeals alleging that the rules did not go far enough were dropped. The appeals alleging that the FCC lacks authority to apply the rules are pending.

Federal - Intercarrier Compensation

On February 9, 2011, the FCC released a Notice of Proposed Rulemaking on reforming universal service and the intercarrier compensation (“ICC”) system that governs payments between telecommunications carriers primarily for terminating traffic. In particular, the FCC indicated that it has never determined the ICC obligations for VoIP service and sought comment on a number of proposals for how VoIP should be treated in the ICC system. The FCC's adoption of an ICC proposal will impact Vonage's costs for telecommunications services. On October 27, 2011, the FCC adopted an order reforming universal service and ICC. The FCC order provides that VoIP originated calls will be subject to interstate access charges for long distance calls and reciprocal compensation for local calls that terminate to the public switched telephone network (“PSTN”). It also subjected PSTN originated traffic directed to VoIP subscribers to similar ICC obligations. The termination charges for all traffic, including VoIP originated traffic, will transition over several years to a bill and keep arrangement (i.e., no termination charges). Numerous parties filed appeals of the FCC order in multiple federal circuit courts of appeal. The 10th Circuit Court of Appeals was selected by lottery to decide the appeals. The appeals are pending.

Federal - Universal Service Contribution Reform

On April 30, 2012, the FCC released a Further Notice of Proposed Rulemaking on reforming federal universal service fund (“USF”) contributions. Currently USF contributions are assessed on the interstate and international revenue of traditional telephone carriers and interconnected VoIP providers like Vonage. The level of USF assessments on these providers has been going up over time because of decreases in the revenue subject to assessment due to substitution of non-assessable services such as non-interconnected VoIP services. If the FCC does reform USF contributions, it is likely that Vonage's contribution burden will decline.

Federal - Rural Call Completion Issues

On February 7, 2013, the FCC released a Notice of Proposed Rulemaking on rural call completion issues. The Notice of Proposed Rulemaking proposes new detailed reporting requirements to gauge rural call completion performance. Rural carriers have argued that VoIP provider call completion performance to rural areas is generally poor. We could be subject to an FCC enforcement action in the future in the event the FCC took the position that our rural call completion performance is inadequate.

Federal - Numbering Rights

On April 18, 2013, the FCC issued a Notice of Proposed Rulemaking (NPRM) that proposes to modify FCC rules to allow VoIP providers to directly access telephone numbers.  In addition, the FCC granted a waiver from its existing rules to allow Vonage to conduct a trial of direct access to telephone numbers.  The trial will allow the FCC to obtain real-world data on direct access to telephone numbers by VoIP providers to inform consideration of the NPRM.  Direct access to telephone numbers would facilitate IP to IP interconnection, which may allow VoIP providers to provide higher quality, lower cost services, promote the deployment of innovative new voice services, and experience reductions in the cost of telephony services. Vonage is currently conducting a trial of direct access to telephone numbers in the Atlanta, Boston, and Phoenix markets.

Pakistan Termination Rate Increase

On October 1, 2012, Pakistani carriers formed the International Clearing House (ICH). This cartel subsequently took action to increase the cost to terminate international calls to Pakistan by approximately 500 percent.  As a result of the implementation of higher termination costs, Vonage was forced to remove Pakistan from unlimited calling in its Vonage World plan.  Vonage filed a petition at the FCC, shortly after the ICH rates became effective, seeking an order prohibiting U.S. carriers from paying the new higher ICH rates.  On March 5, 2013, the FCC issued an order that prohibits U.S. carriers from paying more than the prevailing termination rate prior to the implementation of the ICH rates.  In addition to the Vonage challenge in the U.S., a Pakistani carrier challenged the ICH action under Pakistani competition law.  After the trial court found that the ICH violated Pakistani competition

(Unaudited)

law, the Supreme Court of Pakistan overturned the trial court decision and remanded the case to the Competition Commission of Pakistan (CCP).  On April 30, 2013, the CCP issued an order that holds that the ICH violates Pakistani competition law.  On May 9, 2013, the Sindh High Court temporarily suspended the CCP order while the court considers constitutional challenges to the order made by several Pakistani carriers. Despite favorable action by both U.S. and Pakistani authorities, it is currently unclear if or how long it will take for international termination rates in Pakistan to return to a more competitive level.

State Telecommunications Regulation

In general, the focus of interconnected VoIP telecommunications regulation is at the federal level. On November 12, 2004, the FCC issued a declaratory ruling providing that our service is subject to federal regulation and preempted the Minnesota Public Utilities Commission from imposing certain of its regulations on us. The FCC's decision was based on its conclusion that our service is interstate in nature and cannot be separated into interstate and intrastate components. On March 21, 2007, the United States Court of Appeals for the 8th Circuit affirmed the FCC's declaratory ruling preempting state regulation of our service. The 8th Circuit found that it is impossible for us to separate our interstate traffic from our intrastate traffic because of the nomadic nature of the service. As a result, the 8th Circuit held that it was reasonable for the FCC to preempt state regulation of our service. The 8th Circuit was clear, however, that the preemptive effect of the FCC's declaratory ruling may be reexamined if technological advances allow for the separation of interstate and intrastate components of the nomadic VoIP service. Therefore, the preemption of state authority over our service under this ruling generally hinges on the inability to separate the interstate and intrastate components of the service.While this ruling does not exempt us from all state oversight of our service, it effectively prevents state telecommunications regulators from imposing certain burdensome and inconsistent market entry requirements and certain other state utility rules and regulations on our service. State regulators continue to probe the limits of federal preemption in their attempts to apply state telecommunications regulation to interconnected VoIP service. On July 16, 2009, the Nebraska Public Service Commission and the Kansas Corporation Commission filed a petition with the FCC seeking a declaratory ruling or, alternatively, adoption of a rule declaring that state authorities may apply universal service funding requirements to nomadic VoIP providers. We participated in the FCC proceedings on the petition. On November 5, 2010, the FCC issued a declaratory ruling that allowed states to assess state USF on nomadic VoIP providers on a going forward basis provided that the states comply with certain conditions to ensure that imposing state USF does not conflict with federal law or policy. We expect that state public utility commissions and state legislators will continue their attempts to apply state telecommunications regulations to nomadic VoIP service.

Stand-by Letters of Credit

We had stand-by letters of credit totaling $4,302 and $5,558, as of June 30, 2013 and December 31, 2012, respectively.

End-User Commitments

We are obligated to provide telephone services to our registered end-users. The costs related to the potential utilization of minutes sold are expensed as incurred. Our obligation to provide this service is dependent on the proper functioning of systems controlled by third-party service providers. We do not have a contractual service relationship with some of these providers.

Vendor Commitments

We have committed to purchase international carrier services from a vendor. We have committed to pay this vendor approximately $39,000 in 2013, $78,000 in 2014 and 2015, and $39,000 in 2016, respectively.

We have committed to purchase energy supply from a vendor. We have committed to pay this vendor approximately $600 in 2013, $1,100 in 2014, and $500 in 2015, respectively.

State and Municipal Taxes

In accordance with generally accepted accounting principles, we make a provision for a liability for taxes when it is both probable that a liability has been incurred and the amount of the liability or range of liability can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. For a period of time, we did not collect or remit state or municipal taxes (such as sales, excise, utility, use, and ad valorem taxes), fees or surcharges (“Taxes”) on the charges to our customers for our services, except that we historically complied with the New Jersey sales tax. We have received inquiries or demands from a number of state and municipal taxing and 911 agencies seeking payment of Taxes that are applied to or collected from customers of providers of traditional public switched telephone network services. Although we have consistently maintained that these Taxes do not apply to our service for a variety of reasons depending on the statute or rule that establishes such obligations,

24

(Unaudited)

we are now collecting and remitting sales taxes in certain of those states including a number of states that have changed their statutes to expressly include VoIP. In addition, many states address how VoIP providers should contribute to support public safety agencies, and in those states we remit fees to the appropriate state agencies. We could also be contacted by state or municipal taxing and 911 agencies regarding Taxes that do explicitly apply to VoIP and these agencies could seek retroactive payment of Taxes. As such, we have a reserve of $2,122 as of June 30, 2013 as our best estimate of the potential tax exposure for any retroactive assessment. We believe the maximum estimated exposure for retroactive assessments is approximately $5,000 as of June 30, 2013.

Financial Information Presentation

For the financial information discussed in this Quarterly Report on Form 10-Q, other than per share and per line amounts, dollar amounts are presented in thousands, except where noted. All trademarks are the property of their owners.

Overview

We are a leading provider of communications services connecting people through cloud-connected devices worldwide. We rely heavily on our network, which is a flexible, scalable Session Initiation Protocol (SIP) based Voice over Internet Protocol, or VoIP, network. This platform enables a user via a single “identity,” either a number or user name, to access and utilize services and features regardless of how they are connected to the Internet, including over 3G, 4G, Cable, or DSL broadband networks. This technology enables us to offer our customers attractively priced voice and messaging services and other features around the world on a variety of devices.

Over the past years, we have fundamentally transformed our company - strategically, operationally and financially. Strategically, we shifted our primary focus to serving rapidly growing but under-served ethnic segments in the United States with international calling needs. We improved our value proposition by being the first to deliver flat-rate, unlimited calling primarily from the United States to over 60 countries with the launch of our Vonage World service, and we were the first to provide easy-to-use, enhanced features, like voice-to-text translation and mobile Extension services, at no extra cost. These strategic shifts have resulted in new customers with a higher average lifetime value and a better churn profile than those in the past.

Our focus on operations during this period has resulted in a significantly improved cost structure. We have implemented operational efficiencies throughout our business and have reduced domestic and international termination costs per minute, and customer care costs. Importantly, we have enabled structural cost reductions while significantly improving network call quality and customer service performance. Improvements in the overall customer experience have contributed to lower churn, which was 2.4% at June 30, 2013.

Through debt refinancings in December 2010, July 2011, and February 2013, we have fundamentally improved our balance sheet, reducing annual interest expense from $49 million in 2010 to $6 million in 2012 and reducing interest rates from as high as 20% in 2009 to less than 4% today.

In part as a result of our operational and financial stability, on February 7, 2013, Vonage's Board of Directors discontinued the remainder of our then existing $50,000 share repurchase program effective at the close of business on February 12, 2013 with

26

$16,682 remaining, and authorized a new program to repurchase up to $100,000 of the Company's outstanding shares by December 31, 2014. We believe our repurchase program reflects our balanced approach to capital allocation as we invest for growth through our growth priorities and deliver value to shareholders without compromising our ongoing operational needs. 

Having achieved operational and financial stability, we are focused on driving revenue through three major growth priorities: first, continued penetration of our core North American markets, where we will continue to provide value in international long distance and target under-served ethnic segments, and where we have entered the low-end domestic market with our flanker brand, BasicTalk, a low-priced home phone service offering unlimited calling throughout the United States; second, international expansion outside of North America through strategic partnerships; and third, mobile services, which we view as a strategic enabler of the Company's entire product offering.

We had approximately 2.3 million subscriber lines for broadband telephone replacement services as of June 30, 2013. We bill customers in the United States, Canada, and the United Kingdom. Customers in the United States represented 93% of our subscriber lines at June 30, 2013.

Trends and Key Operating Data

A number of trends have a significant effect on our results of operations and are important to an understanding of our financial statements.

Competitive landscape. We face intense competition from traditional telephone companies, wireless companies, cable companies, and alternative communication providers. Most traditional wireline and wireless telephone service providers and cable companies are substantially larger and better capitalized than we are and have the advantage of a large existing customer base. In addition, because our competitors provide other services, they often choose to offer VoIP services or other voice services as part of a bundle that includes other products, such as video, high speed Internet access, and wireless telephone service, which we do not offer. In addition, such competitors may in the future require new customers or existing customers making changes to their service to purchase voice services when purchasing high speed Internet access. Further, as wireless providers offer more minutes at lower prices, better coverage, and companion landline alternative services, their services have become more attractive to households as a replacement for wireline service. We also compete against alternative communication providers, such as magicJack, Skype, and Google Voice. Some of these service providers have chosen to sacrifice telephony revenue in order to gain market share and have offered their services at low prices or for free. As we continue to introduce applications that integrate different forms of voice and messaging services over multiple devices, we are facing competition from emerging competitors focused on similar integration, as well as from alternative voice communication providers. In addition, our competitors have partnered and may in the future partner with other competitors to offer products and services, leveraging their collective competitive positions. We also are subject to the risk of future disruptive technologies. In connection with our increasing emphasis on the international long distance market in the United States, we face competition from low-cost international calling cards and VoIP providers in addition to traditional telephone companies, cable companies, and wireless companies.

Broadband adoption. The number of United States households with broadband Internet access has grown significantly. On March 16, 2010, the Federal Communications Commission (“FCC”) released its National Broadband Plan, which seeks, through supporting broadband deployment and programs, to encourage broadband adoption for the approximately 100 million United States residents who do not have broadband at home. We expect the trend of greater broadband adoption to continue. We benefit from this trend because our service requires a broadband Internet connection and our potential addressable market increases as broadband adoption increases.

Regulation. Our business has developed in a relatively lightly regulated environment. The United States and other countries, however, are examining how VoIP services should be regulated. The November 2010 order by the FCC in response to a request by Kansas and Nebraska that permits states to impose state universal service fund obligations on VoIP service, discussed in Note 6 to our financial statements, is an example of efforts by regulators to determine how VoIP service fits into the telecommunications regulatory landscape. In addition to regulatory matters that directly address VoIP, a number of other regulatory initiatives could impact our business. One such regulatory initiative is net neutrality. In December 2010, the FCC adopted a revised set of net neutrality rules for broadband Internet service providers. These rules make it more difficult for broadband Internet service providers to block or discriminate against Vonage service. Several broadband Internet service providers have filed appeals of the FCC's new rules at the D.C. Circuit Court of Appeals alleging that the FCC lacks authority to apply its rules to broadband Internet service providers. In addition, on October 27, 2011, the FCC adopted an order reforming universal service and intercarrier compensation. The FCC order provides that VoIP originated calls will be subject to interstate access charges for long distance calls and reciprocal compensation for local calls that terminate to the public switched telephone network (“PSTN”). The termination charges for all traffic, including VoIP originated traffic, will transition over several years to a bill and keep arrangement (i.e., no termination charges). We believe that the order will positively impact our costs over time. Numerous parties filed appeals of the FCC order that are pending. On April 18, 2013, the FCC issued a Notice of Proposed Rulemaking (NPRM) that proposes to modify FCC rules to allow VoIP providers to directly access telephone numbers.  In addition, the FCC granted a waiver from its existing rules

27

to allow Vonage to conduct a trial of direct access to telephone numbers.  The trial will allow the FCC to obtain real-world data on direct access to telephone numbers by VoIP providers to inform consideration of the NPRM.  Direct access to telephone numbers would facilitate IP to IP interconnection, which may allow VoIP providers to provide higher quality, lower cost services, promote the deployment of innovative new voice services, and experience reductions in the cost of telephony services. Vonage is currently conducting a trial of direct access to telephone numbers in the Atlanta, Boston, and Phoenix markets.

The table below includes key operating data that our management uses to measure the growth and operating performance of our business:

	Three Months Ended						Six Months Ended

Marketing costs per gross subscriber line addition	$	375		$	336		$	363		$	330
Employees (excluding temporary help) (at period end)	946			988			946			988

Gross subscriber line additions. Gross subscriber line additions for a particular period are calculated by taking the net subscriber line additions during that particular period and adding to that the number of subscriber lines that terminated during that period. This number does not include subscriber lines both added and terminated during the period, where termination occurred within the first 30 days after activation. The number does include, however, subscriber lines added during the period that are terminated within 30 days of activation but after the end of the period.

Net subscriber line additions. Net subscriber line additions for a particular period reflect the number of subscriber lines at the end of the period, less the number of subscriber lines at the beginning of the period.

Subscriber lines. Our subscriber lines include, as of a particular date, all paid subscriber lines from which a customer can make an outbound telephone call on that date. Our subscriber lines include fax lines including fax lines bundled with subscriber lines in our small office home office calling plans and soft phones but do not include our virtual phone numbers or toll free numbers, which only allow inbound telephone calls to customers. Subscriber lines decreased from 2,356,084 as of June 30, 2012 to 2,349,957 as of June 30, 2013. For the three months ended June 30, 2013, we added 155,412 subscriber lines. We believe that the decrease in our subscriber lines from the prior year was primarily due to increasing competition, particularly from cable companies and alternative voice communication providers.

Average monthly customer churn. Average monthly customer churn for a particular period is calculated by dividing the number of customers that terminated during that period by the simple average number of customers during the period, and dividing the result by the number of months in the period. The simple average number of customers during the period is the number of customers on the first day of the period, plus the number of customers on the last day of the period, divided by two. Terminations, as used in the calculation of churn statistics, do not include customers terminated during the period if termination occurred within the first 30 days after activation. Our average monthly customer churn decreased from 2.5% for the three months ended June 30, 2012 and the three months ended March 31,2013 to 2.4% for the three months ended June 30, 2013. Our average monthly customer churn decreased from 2.7% for the six months endedJune 30, 2012 to 2.5% for the six months endedJune 30, 2013. The decline is the result of improvements in overall customer satisfaction, as well as changes in retention processes and the impact of service agreements, which were put in place in February 2012.We monitor churn on a daily basis and use it as an indicator of the level of customer satisfaction. Other companies may calculate churn differently, and their churn data may not be directly comparable to ours. Customers who have been with us for a year or more tend to have a lower churn rate than customers who have not. In addition, our customers who are international callers generally churn at a lower rate than customers who are domestic callers. Our churn will fluctuate over time due to economic conditions, competitive pressures, marketplace perception of our services, and our ability to provide high quality customer care and network quality and add future innovative products and services.

Average monthly revenues per line. Average monthly revenues per line for a particular period is calculated by dividing our revenues for that period by the simple average number of subscriber lines for the period, and dividing the result by the number of months in the period. The simple average number of subscriber lines for the period is the number of subscriber lines on the first day of the period, plus the number of subscriber lines on the last day of the period, divided by two. Our average monthly revenues

28

per line decreased slightly to $29.06 for the three months ended June 30, 2013 compared to $29.98 for the three months ended June 30, 2012 due primarily to rate plan mix and lower USF fees. The continued expansion of lower priced plan offerings including BasicTalk to meet customer segment needs may cause downward pressure on average monthly revenues per line, offset by any selected pricing actions.

Average monthly direct cost of telephony services per line. Average monthly direct cost of telephony services per line for a particular period is calculated by dividing our direct cost of telephony services for that period by the simple average number of subscriber lines for the period, and dividing the result by the number of months in the period. We use the average monthly direct cost of telephony services per line to evaluate how effective we are at managing our costs of providing service. Our average monthly direct cost of telephony services per line decreased to $7.60 for the three months ended June 30, 2013 compared to $8.23 for the three months ended June 30, 2012, due primarily to the decrease in domestic and international termination costs due to a lower customer base and more favorable rates negotiated with our service providers, the decrease in our network costs and in our E-911 costs, and the decrease in regulatory fees. Direct cost of telephony services both overall and on a per line basis is expected to experience upward pressure from increased international calling by our base of Vonage World customers offset by implementation of intelligent call routing and peering relationships, and improved pricing from various carriers.

Marketing cost per gross subscriber line addition. Marketing cost per gross subscriber line addition is calculated by dividing our marketing expense for a particular period by the number of gross subscriber line additions during the period. Marketing expense does not include the cost of certain customer acquisition activities, such as rebates and promotions, which are accounted for as an offset to revenues, or customer equipment subsidies, which are accounted for as direct cost of goods sold. As a result, it does not represent the full cost to us of obtaining a new customer. Our marketing cost per gross subscriber line addition was higher at $375 for the three months ended June 30, 2013 compared to $336 for the three months ended June 30, 2012 as a result of our investment for the nationwide launch of BasicTalk including a portion of costs that were fixed and not variable with subscriber line additions.

Employees. Employees represent the number of personnel that are on our payroll and exclude temporary or outsourced labor.

Revenues

Revenues consists of telephony services revenue and customer equipment and shipping revenue. Substantially all of our revenues are telephony services revenue. In the United States, we offer domestic and international rate plans to meet the needs of our customers, including a variety of residential plans, mobile plans, and small office and home office calling plans. The “Vonage World” plan, now available in the United States and Canada, offers unlimited calling across the United States and Puerto Rico, unlimited international calling to over 60 countries including India, Mexico, and China, subject to certain restrictions, and free voicemail to text messages with Vonage Visual Voicemail. Each of our unlimited plans other than Vonage World offers unlimited domestic calling in the United States as well as unlimited calling to Puerto Rico, Canada, and selected European countries, subject to certain restrictions. Each of our basic plans offers a limited number of domestic calling minutes per month. We offer similar plans in Canada and the United Kingdom. Under our basic plans, we charge on a per minute basis when the number of domestic calling minutes included in the plan is exceeded for a particular month. International calls (except for calls to Puerto Rico, Canada and certain European countries under our unlimited plans and a variety of countries under international calling plans and Vonage World) are charged on a per minute basis. These per minute fees are not included in our monthly subscription fees.

In addition to our landline telephony business, we are leveraging our technology to offer services and applications for mobile and other connected devices to address large existing markets. We introduced our first mobile offering in late 2009 and in early 2012 we introduced Vonage Mobile, our all-in-one mobile application that now provides free voice and video calling and messaging between users who have the application, as well as traditional paid international calling to any other phone. This mobile application works over WiFi, 3G and 4G and in more than 90 countries worldwide. The application consolidates the best features of our prior applications, while adding important functionality, value and ease of use including direct payment through iTunes.

We derive substantially all of our telephony services revenue from monthly subscription fees that we charge our customers under our service plans. We also offer residential fax service, virtual phone numbers, toll free numbers and other services, and charge an additional monthly fee for each service. One business fax line is included with each of our two small office and home office plans, but we charge monthly fees for additional business fax lines. We automatically charge these fees to our customers’ credit cards, debit cards, or electronic check payments (“ECP”), monthly in advance. We also automatically charge the per minute fees not included in our monthly subscription fees to our customers’ credit cards, debit cards or ECP monthly in arrears unless they exceed a certain dollar threshold, in which case they are charged immediately.

By collecting monthly subscription fees in advance and certain other charges immediately after they are incurred, we are able to reduce the amount of accounts receivable that we have outstanding, thus allowing us to have lower working capital requirements. Collecting in this manner also helps us mitigate bad debt losses, which are recorded as a reduction to revenue. If a customer’s credit card, debit card or ECP is declined, we generally suspend international calling capabilities as well as the customer’s

29

ability to incur domestic usage charges in excess of their plan minutes. Historically, in most cases, we are able to correct the problem with the customer within the current monthly billing cycle. If the customer’s credit card, debit card or ECP could not be successfully processed during three billing cycles (i.e., the current and two subsequent monthly billing cycles), we terminate the account.

In the United States, we charge regulatory, compliance, E-911, and intellectual property-related recovery fees on a monthly basis to defray costs, and to cover taxes that we are charged by the suppliers of telecommunications services. In addition, we recognize revenue on a gross basis for contributions to the Federal Universal Service Fund (“USF”) and related fees. All other taxes are recorded on a net basis.

In addition, historically, we charged a disconnect fee for customers who terminated their service plan within the first twelve months of service. Disconnect fees are recorded as revenue and are recognized at the time the customer terminates service. Beginning in September 2010, we eliminated the disconnect fee for new customers. In February of 2012 we re-introduced service agreements as an option for new customers.

Telephony services revenue is offset by the cost of certain customer acquisition activities, such as rebates and promotions.

Customer equipment and shipping revenues, comprising an incidental portion of our revenue, derives from revenue from sales of customer equipment to our wholesalers or directly to customers and retailers. In addition, customer equipment and shipping revenue includes the fees, when collected, that we charge our customers for shipping any equipment to them.

Operating Expenses

Operating expenses consist of direct cost of telephony services, direct cost of goods sold, selling, general and administrative expense, marketing expense, and depreciation and amortization.

Direct cost of telephony services. Direct cost of telephony services primarily consists of fees that we pay to third parties on an ongoing basis in order to provide our services. These fees include:

• Access charges that we pay to other telephone companies to terminate domestic and international calls on the public switched telephone network. These costs represented approximately 51% and 48% of our total direct cost of telephony services for the three months ended June 30, 2013 and 2012, respectively, with a portion of these payments ultimately being made to incumbent telephone companies. When a Vonage subscriber calls another Vonage subscriber, we do not pay an access charge.

• The cost of leasing Internet transit services from multiple Internet service providers. This Internet connectivity is used to carry VoIP session initiation signaling and packetized audio media between our subscribers and our regional data centers.

• The cost of leasing from other telephone companies the telephone numbers that we provide to our customers. We lease these telephone numbers on a monthly basis.

• The cost of co-locating our regional data connection point equipment in third-party facilities owned by other telephone companies, Internet service providers or collocation facility providers.

• The cost of providing local number portability, which allows customers to move their existing telephone numbers from another provider to our service. Only regulated telecommunications providers have access to the centralized number databases that facilitate this process. Because we are not a regulated telecommunications provider, we must pay other telecommunications providers to process our local number portability requests.

• The cost of complying with FCC regulations regarding VoIP emergency services, which require us to provide enhanced emergency dialing capabilities to transmit 911 calls for our customers.

• Taxes that we pay on our purchase of telecommunications services from our suppliers or imposed by government agencies such as Federal USF and related fees.

Direct cost of goods sold. Direct cost of goods sold primarily consists of costs that we incur when a customer first subscribes to our service. These costs include:

• The cost of the equipment that we provide to customers who subscribe to our service through our direct sales channel in excess of activation fees when an activation fee is collected. The remaining cost of customer equipment is deferred up to the activation fee collected and amortized over the estimated average customer life.

• The cost of the equipment that we sell directly to retailers.

30

• The cost of shipping and handling for customer equipment, together with the installation manual, that we ship to customers.

• The cost of certain products or services that we give customers as promotions.

Selling, general and administrative expense. Selling, general and administrative expense includes:

• Compensation and benefit costs for all employees, which is the largest component of selling, general and administrative expense and includes customer care, research and development, network engineering and operations, sales and marketing, executive, legal, finance, and human resources personnel.

• Share-based expense related to share-based awards to employees, directors, and consultants.

• Outsourced labor related to customer care, kiosk and events sales teams, and retail support activities.

• Product awareness advertising.

• Transaction fees paid to credit card, debit card, and ECP companies and other third party billers such as iTunes, which may include a per transaction charge in addition to a percent of billings charge.

• Rent and related expenses.

• Professional fees for legal, accounting, tax, public relations, lobbying, and development activities.

• Litigation settlements.

Marketing expense. Marketing expense includes:

• Advertising costs, which comprise a majority of our marketing expense and include online, television, direct mail, alternative media, promotions, sponsorships, and inbound and outbound telemarketing.

• Creative and production costs.

• The costs to serve and track our online advertising.

• Certain amounts we pay to retailers for activation commissions.

• The cost associated with our customer referral program.

Depreciation and amortization expenses. Depreciation and amortization expenses include:

• Depreciation of our network equipment, furniture and fixtures, and employee computer equipment.

• Amortization of leasehold improvements and purchased and developed software.

• Amortization of intangible assets (patents and trademarks).

• Loss on disposal or impairment of property and equipment.

Loss from abandonment of software assets. Loss from abandonment of software assets include:

• Impairment of investment in software assets.

Other Income (Expense)

Other Income (Expense) includes:

• Interest income on cash and cash equivalents.

• Interest expense on notes payable, patent litigation judgments and settlements and capital leases.

• Amortization of debt related costs.

• Realized and unrealized gains (losses) on foreign currency.

Revenues. For the three months ended June 30, 2013, revenues decreased by $7,140, or 3%, compared to the three months ended June 30, 2012. This was primarily driven by a decrease of $7,190 in monthly subscription fees resulting from a decreased number of subscription lines, which reduced from 2,356,084 at June 30, 2012 to 2,349,957 at June 30, 2013, and retention activities. There was an increase in credits issued to subscribers of $1,481. These revenue decreases were offset by an increase in fees that we charged for disconnecting our service of $602 and an increase in our regulatory fee revenue of $1,688, which includes a decrease of $2,674 in USF fees offset by an increase in regulatory recovery fees and E-911 fees of $4,362.

32

For the six months endedJune 30, 2013, revenues decreased by $13,956, or 3%, compared to the six months endedJune 30, 2012. This was primarily driven by a decrease of $14,542 in monthly subscription fees resulting from a decreased number of subscription lines, which reduced from 2,356,084 at June 30, 2012 to 2,349,957 at June 30, 2013, and retention activities. There was also a decrease in activation fees of $725 and a decrease in other revenue of $748 due to lower rates from our revenue sharing partners. There was an increase in credits issued to subscribers of $2,229 and a decrease in additional features revenue of $542. These decreases were offset by an increase in fees that we charged for disconnecting our service of $1,734 due to reinstatement of contracts for new customers beginning in February 2012, and an increase in our regulatory fee revenue of $3,438, which includes a decrease of $5,193 in USF fees offset by an increase in regulatory recovery fees and E-911 fees of $8,631.

Direct cost of telephony services. For the three months ended June 30, 2013 compared to the three months ended June 30, 2012, the decrease in direct cost of telephony services of $4,668, or 8%, was primarily driven by a decrease in domestic termination costs of $429 due to improved termination rates, which are costs that we pay other phone companies for terminating phone calls, and fewer minutes of use and a decrease in our network costs of $986, which includes costs for co-locating in other carriers’ facilities, leasing phone numbers, routing calls on the Internet, E-911 costs, and transferring calls to and from the Internet to the public switched telephone network. There was also a decrease in international usage of $563 driven by improved termination rates, and a decrease of USF and related fees imposed by government agencies of $2,674.

For the six months endedJune 30, 2013 compared to the six months endedJune 30, 2012, the decrease in direct cost of telephony services of $11,110, or 9%, was primarily driven by a decrease in domestic termination costs of $757 due to improved termination rates, which are costs that we pay other phone companies for terminating phone calls, and fewer minutes of use and a decrease in our network costs of $2,886, which includes costs for co-locating in other carriers’ facilities, leasing phone numbers, routing calls on the Internet, E-911 costs, and transferring calls to and from the Internet to the public switched telephone network. There was also a decrease in other costs of $447, a decrease in international usage of $1,826 driven by improved termination rates, and a decrease of USF and related fees imposed by government agencies of $5,193.

Direct cost of goods sold. For the three months ended June 30, 2013 compared to the three months ended June 30, 2012, the decrease in direct cost of goods sold of $58, or 1%, was primarily due to a decrease in waived activation fees for new customers of $1,120 due to lower direct customer adds offset by an increase in customer equipment costs of $1,403 from additional customers from our retail expansion.

For the six months endedJune 30, 2013 compared to the six months endedJune 30, 2012, the decrease in direct cost of goods sold of $1,026, or 5%, was primarily due to a decrease in amortization costs on deferred customer equipment of $428, a decrease in waived activation fees for new customers of $2,621 due to lower direct customer adds, and a decrease in shipping costs of $603. These decreases were offset by an increase in customer equipment costs of $2,628 from additional customers from our retail expansion.

Selling, general and administrative. For the three months ended June 30, 2013 compared to the three months ended June 30, 2012, selling expense increased by $4,015 including $1,561 due to the expansion of the number of community sales teams and $2,589 due to an increase in the number of retail stores with assisted selling and the nationwide BasicTalk launch. For the three months ended June 30, 2013 compared to the three months ended June 30, 2012, general and administrative expense decreased by $930 due mainly to resolution of an insurance claim for prior period legal fees and settlement expenses of $2,300, lower Customer Care costs of $2,185, and a decrease in other expense of $820. These decreases were offset by higher share based cost of $915 and an increase in compensation and employee related expense of $3,106.

For the six months endedJune 30, 2013 compared to the six months endedJune 30, 2012, selling expense increased by $4,300 including $2,003 due to the expansion of the number of community sales teams and $4,128 due to an increase in the number of retail stores with assisted selling and the nationwide BasicTalk launch, offset by a decrease of $1,851 related to product awareness advertising of our mobile offering launched in February 2012. For the six months endedJune 30, 2013 compared to the six months endedJune 30, 2012, general and administrative expense decreased by $140 due mainly to resolution of an insurance claim for prior period legal fees and settlement expenses of $2,300, lower Customer Care costs of $4,443, a decrease in telecommunications expenses of $876, and a decrease in facility expense of $548. There was also a decrease in other expense of $889. These decreases

Marketing. For the three months ended June 30, 2013 compared to the three months ended June 30, 2012, marketing expense increased by $3,374, or 6%, as a result of our investment for the nationwide launch of BasicTalk including a portion of costs that were fixed and not variable with subscriber line additions.

For the six months endedJune 30, 2013 compared to the six months endedJune 30, 2012, marketing expense increased slightly by $1,621, or 1%, as a result of our investment for the nationwide launch of BasicTalk including a portion of costs that were fixed and not variable with subscriber line additions.

We expect to make incremental investment in the nationwide launch of BasicTalk above second quarter levels in order to continue to build awareness, drive traffic, and provide merchandise support.

Depreciation and amortization. The decrease in depreciation and amortization of $313, or 4%, for the three months ended June 30, 2013 compared to the three months ended June 30, 2012, was primarily due to lower depreciation of network equipment, computer hardware, and furniture of $517, offset by an increase in software amortization of $260.

The decrease in depreciation and amortization of $982, or 6%, for the six months endedJune 30, 2013 compared to the six months endedJune 30, 2012, was primarily due to lower depreciation of network equipment, computer hardware, and furniture of $1,127, offset by an increase in software amortization of $216.

Interest expense. For the three months endedJune 30, 2013 compared to the three months endedJune 30, 2012, the increase in interest expense of $166, or 11%, was due mainly to an increase in interest expense related to tax audits of $222, offset by a decrease in interest expense driven by our credit facility entered into in connection with our refinancing in February 2013 and the final payoff of a settlement agreement in August 2012.

For the six months endedJune 30, 2013 compared to the six months endedJune 30, 2012, the decrease in interest expense of $128, or 4%, was due to a decrease of $136 driven by our credit facility entered into in connection with our refinancing in February 2013 and a decrease of $207 due to the payoff of a settlement agreement in August 2012, offset by an increase in interest expense related tax audits of $222.

Effective tax rate	39.7		%	22.1		%						38.6		%	27.3		%

We recognize income tax expense equal to our pre-tax income multiplied by our effective income tax rate, an expense that had not been recognized prior to the reduction of the valuation allowance in the fourth quarter of 2011. In addition, adjustments are recorded for discrete period items related to stock compensation and changes to our state effective tax rate.

The provision also includes the federal alternative minimum tax and state and local income taxes.

The effective tax rate is calculated by dividing the income tax expense by income before income tax expense. The effective rate for the six months endedJune 30, 2012 was less than the federal statutory rate due, in part, to our Canadian operations and certain discrete period items, which primarily consisted of adjustments related to stock compensation, including a non-cash deferred tax adjustment totaling $4,077 for certain stock compensation previously considered nondeductible under Section 162(m) of the Internal Revenue Code. The 2013 estimated annual effective tax rate is expected to approximate 41%, but may fluctuate each quarter due to the timing of other discrete period transactions.

Net income (loss). Based on the explanations described above, our net income of $7,447 for the three months ended June 30, 2013 increased by $10,787, or 323%, from net loss of $3,340 for the three months ended June 30, 2012.

Based on the explanations described above, our net income of $20,494 for the six months endedJune 30, 2013 increased by $9,913, or 94%, from net income of $10,581 for the six months endedJune 30, 2012.

Liquidity and Capital Resources

Overview

The following table sets forth a summary of our cash flows for the periods indicated:

	Six Months Ended
	June 30,
	2013			2012
	(in thousands)
Net cash provided by operating activities	$	28,604		$	40,640
Net cash used in investing activities	(10,744		)	(12,341		)
Net cash used in financing activities	(14,921		)	(14,615		)

For the six months endedJune 30, 2013, we generated income from operations. We expect to continue to balance efforts to grow our customer base while consistently achieving operating profitability. To grow our customer base, we continue to make investments in marketing, application development as we seek to launch new services, network quality and expansion, and customer care. Although we believe we will achieve consistent profitability in the future, we ultimately may not be successful and we may not achieve consistent profitability. We believe that cash flow from operations and cash on hand will fund our operations for at least the next twelve months.

2013 Financing

On February 11, 2013 we entered into Amendment No. 1 to our July 2011 Credit Agreement (as further amended by Amendment No. 2 to our 2011 Credit Facility, the "2013 Credit Facility"). The 2013 Credit Facility consists of a $70,000 senior secured term loan and a $75,000 revolving credit facility. The co-borrowers under the 2013 Credit Facility are our wholly owned subsidiary, Vonage America Inc., and us. Obligations under the 2013 Credit Facility are guaranteed, fully and unconditionally, by our other United States subsidiaries and are secured by substantially all of the assets of each borrower and each of the guarantors. On July 26, 2013 we entered into Amendment No. 2 to our 2011 Credit Agreement, which amends our financial covenant related to our consolidated fixed charge coverage ratio by increasing the amount of restricted payments excluded from such calculation from $50,000 to $80,000.

Use of Proceeds

The net proceeds received of $27,500 from the senior secured term loan and the undrawn revolving credit facility under the 2013 Credit Facility will be used for general corporate purposes. We also incurred $2,009 of fees in connection with the 2013 Credit Facility, which is amortized, along with the unamortized fees of $670 in connection with the 2011 Credit Facility, to interest expense over the life of the debt using the effective interest method.

2013 Credit Facility Terms

The following description summarizes the material terms of the 2013 Credit Facility:

The loans under the 2013 Credit Facility mature in February 2016. Principal amounts under the 2013 Credit Facility are repayable in quarterly installments of $5,833 per quarter for the senior secured term loan. The unused portion of our revolving credit facility incurs a 0.45% commitment fee.

Outstanding amounts under the 2013 Credit Facility, at our option, will bear interest at:

• LIBOR (applicable to one-, two-, three- or six-month periods) plus an applicable margin equal to 3.125% if our consolidated leverage ratio is less than 0.75 to 1.00, 3.375% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 3.625% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last day of each relevant interest period or, if the interest period is longer than three months, each day that is three months after the first day of the interest period, or

• the base rate determined by reference to the highest of (a) the federal funds effective rate from time to time plus 0.50%, (b) the prime rate of JPMorgan Chase Bank, N.A., and (c) the LIBOR rate applicable to one month interest periods plus 1.00%, plus an applicable margin equal to 2.125% if our consolidated leverage ratio is less than 0.75 to 1.00, 2.275% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 2.625% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last business day of each March, June, September, and December and the maturity date of the 2013 Credit Facility.

36

The 2013 Credit Facility provides greater flexibility to us in funding acquisitions and restricted payments, such as stock buybacks, than the 2011 Credit Facility.

We may prepay the 2013 Credit Facility at our option at any time without premium or penalty. The 2013 Credit Facility is subject to mandatory prepayments in amounts equal to:

• 100% of the net cash proceeds from any non-ordinary course sale or other disposition of our property and assets for consideration in excess of a certain amount subject to customary reinvestment provisions and certain other exceptions and

• 100% of the net cash proceeds received in connection with other non-ordinary course transactions, including insurance proceeds not otherwise applied to the relevant insurance loss.

Subject to certain restrictions and exceptions, the 2013 Credit Facility permits us to obtain one or more incremental term loans and/or revolving credit facilities in an aggregate principal amount of up to $60,000 plus an amount equal to repayments of the senior secured term loan upon providing documentation reasonably satisfactory to the administrative agent, without the consent of the existing lenders under the 2013 Credit Facility. The 2013 Credit Facility includes customary representations and warranties and affirmative covenants of the borrowers. In addition, the 2013 Credit Facility contains customary negative covenants, including, among other things, restrictions on the ability of us and our subsidiaries to consolidate or merge, create liens, incur additional indebtedness, dispose of assets, consummate acquisitions, make investments, and pay dividends and other distributions. We must also comply with the following financial covenants:

• a consolidated leverage ratio of no greater than 2.00 to 1.00;

• a consolidated fixed coverage charge ratio of no less than 1.75 to 1.00 subject to adjustment to exclude up to $80,000 in specified restricted payments;

• minimum cash of $25,000 including the unused portion of the revolving credit facility or $35,000 in the event of certain specified corporate actions; and

• maximum capital expenditures not to exceed $55,000 during any fiscal year, provided that the unused amount of any permitted capital expenditures in any fiscal year may be carried forward to the next following fiscal year; in addition, annual excess cash flow up to $8,000 increases permitted capital expenditures.

As of June 30, 2013, we were in compliance with all covenants, including financial covenants, for the 2013 Credit Facility.

The 2013 Credit Facility contains customary events of default that may permit acceleration of the debt. During the continuance of a payment default, interest will accrue at a default interest rate of 2% above the interest rate which would otherwise be applicable, in the case of loans, and at a rate equal to the rate applicable to base rate loans plus 2%, in the case of all other amounts.

State and Local Sales Taxes

We also have contingent liabilities for state and local sales taxes. As of June 30, 2013, we had a reserve of $2,122. If our ultimate liability exceeds this amount, it could affect our liquidity unfavorably. However, we do not believe it will significantly impair our liquidity.

Capital Expenditures

For the six months endedJune 30, 2013, capital expenditures were primarily for the implementation of software solutions and purchase of network equipment as we continue to expand our network. Our capital expenditures for the six months endedJune 30, 2013 were $12,000, of which $6,197 was for software acquisition and development. The majority of these expenditures are comprised of investments in information technology and systems infrastructure, including an electronic data warehouse, online customer service, and customer management platforms. For 2013, we believe our capital and software expenditures will be no greater than $30,000.

Common Stock Repurchases

On July 25, 2012, our board of directors approved a plan to buy back up to $50,000 of Vonage common stock through December 31, 2013. The specific timing and amount of repurchases would vary based on available capital resources and other financial and operational performance, market conditions, securities law limitations, and other factors. The repurchases would be made using our cash resources. The repurchase program was subject to suspension or discontinuation at any time without prior notice. For the period from January 1, 2013 to February 12, 2013, we repurchased $5,374, or 2,189 shares of Vonage common stock under the $50,000 repurchase program.

On February 7, 2013, Vonage's Board of Directors discontinued the remainder of our existing $50,000 repurchase program effective at the close of business on February 12, 2013 with $16,682 remaining, and authorized a new program to repurchase up to $100,000 of the Company's outstanding shares by December 31, 2014. The specific timing and amount of repurchases would

37

vary based on available capital resources and other financial and operational performance, market conditions, securities law limitations, and other factors. The repurchases will be made using our cash resources. The repurchase program may be suspended or discontinued at any time without prior notice. For the three months ended June 30, 2013, we repurchased $13,451, or 4,756 shares of Vonage common stock under the $100,000 repurchase program. For the six months endedJune 30, 2013, we repurchased $24,458, or 8,795 shares of Vonage common stock under the $100,000 repurchase program.

In any period under either repurchase program, cash used in financing activities related to common stock repurchases may differ from the comparable change in stockholders' equity, reflecting timing differences between the recognition of share repurchase transactions and their settlement for cash.

Stock Option Cancellation

As part of our strategy to build shareholder value and to facilitate our goal of reducing the number of shares of common stock outstanding, on February 19, 2013, we entered into an agreement with our Chief Executive Officer to cancel a total of 4,500 of his vested stock options for $5,463. The payment reflects a discount, in favor of the Company, from the closing price of the common stock on the New York Stock Exchange on February 19, 2013.

Operating Activities

Cash provided by operating activities decreased to $28,604 for the six months endedJune 30, 2013 compared to $40,640 for the six months endedJune 30, 2012, primarily due to planned investments in our growth priorities, lower revenues and changes in working capital.

Changes in working capital requirements include changes in accounts receivable, inventory, prepaid and other assets, accounts payable, accrued and other liabilities, and deferred revenue and costs. Cash used for working capital requirements increased by $6,451 during the six months endedJune 30, 2013 compared to the prior year period primarily due to timing of payments.

Investing Activities

Cash used in investing activities for the six months endedJune 30, 2013 of $10,744 was attributable to capital expenditures of $5,803 and development of software assets of $6,197, offset by a decrease in restricted cash of $1,256 due primarily to the return of part of the security deposit of $1,000 on our leased office property in Holmdel, New Jersey and the release of our letter of credit from our energy purchase plan of $256.

Cash used in investing activities for the six months ended June 30, 2012 of $12,341 was attributable to capital expenditures of $3,692 and development of software assets of $9,647, offset by a decrease in restricted cash of $998 due primarily to the return of part of the security deposit on our leased office property in Holmdel, New Jersey.

Financing Activities

Cash used in financing activities for the six months endedJune 30, 2013 of $14,921 was primarily attributable to $11,667 in 2013 Credit Facility principal payments, $1,184 in capital lease payments, $30,066 in common stock repurchases, and $2,009 in 2013 Credit Facility debt related costs, partially offset by $27,500 in net proceeds received from our 2013 Credit Facility, and $7,968 in proceeds received from the exercise of stock options offset by $5,463 in proceeds paid in connection with the stock option cancellation.

Cash used in financing activities for the six months ended June 30, 2012 of $14,615 was primarily attributable to $14,167 in 2011 Credit Facility principal payments and $1,006 in capital lease payments, offset by $558 in proceeds received from the exercise of stock options.

Summary of Critical Accounting Policies and Estimates

Our significant accounting policies are summarized in Note 1 to our consolidated financial statements. The following describes our critical accounting policies and estimates:

Use of Estimates

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.

On an ongoing basis, we evaluate our estimates, including the following:

• the useful lives of property and equipment, software costs, and intangible assets;

38

• assumptions used for the purpose of determining share-based compensation using the Black-Scholes option pricing model (“Model”), and various other assumptions that we believed to be reasonable. The key inputs for this Model are our stock price at valuation date, exercise price, the dividend yield, risk-free interest rate, life in years, and historical volatility of our common stock; and

• assumptions used in determining the need for, and amount of, a valuation allowance on net deferred tax assets.

We base our estimates on historical experience, available market information, appropriate valuation methodologies, and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.

Revenue Recognition

The point in time at which revenues are recognized is determined in accordance with Staff Accounting Bulletin No. 104, Revenue Recognition, and Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition.

At the time a customer signs up for our telephony services, there are the following deliverables:

• Providing equipment, if any, to the customer that enables our telephony services and

• Providing telephony services.

The equipment is provided free of charge to our customers and in most instances there are no fees collected at sign-up. We record the fees collected for shipping the equipment to the customer, if any, as shipping and handling revenue at the time of shipment.

A further description of our revenues is as follows:

Substantially all of our operating revenues are telephony services revenues, which are derived primarily from monthly subscription fees that customers are charged under our service plans. We also derive telephony services revenues from per minute fees for international calls if not covered under a plan, including applications for mobile devices and other stand-alone products, and for any calling minutes in excess of a customer's monthly plan limits. Monthly subscription fees are automatically charged to customers' credit cards, debit cards or electronic check payments, or ECP, in advance and are recognized over the following month when services are provided. Revenues generated from international calls and from customers exceeding allocated call minutes under limited minute plans are recognized as services are provided, that is, as minutes are used, and are billed to a customer's credit cards, debit cards or ECP in arrears. As a result of our multiple billing cycles each month, we estimate the amount of revenues earned from international calls and from customers exceeding allocated call minutes under limited minute plans but not billed from the end of each billing cycle to the end of each reporting period and record these amounts as accounts receivable. These estimates are based primarily upon historical minutes and have been consistent with our actual results.

We also provide rebates to customers who purchase their customer equipment from retailers and satisfy minimum service period requirements. These rebates in excess of activation fees are recorded as a reduction of revenues over the service period based upon the estimated number of customers that will ultimately earn and claim the rebates.

Customer equipment and shipping revenues, comprising an incidental portion of our revenue, include sales to our retailers, who subsequently resell this customer equipment to customers. Revenues were reduced for payments to retailers and rebates to customers, who purchased their customer equipment through these retailers, to the extent of customer equipment and shipping revenues.

Inventory

Inventory consists of the cost of customer equipment and is stated at the lower of cost or market, with cost determined using the average cost method. We provide an inventory allowance for customer equipment that has been returned by customers but may not be able to be reissued to new customers or returned to the manufacturer for credit.

Income Taxes

We recognize deferred tax assets and liabilities at enacted income tax rates for the temporary differences between the financial reporting bases and the tax bases of our assets and liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. Our net deferred tax assets primarily consist of net operating loss carry forwards (“NOLs”). We are required to record a valuation allowance against our net deferred tax assets if we conclude that it is more likely than not that taxable income generated in the future will be insufficient to utilize the future income tax benefit

39

from our net deferred tax assets (namely, the NOLs) prior to expiration. We periodically review this conclusion, which requires significant management judgment. If we are able to conclude in a future period that a future income tax benefit from our net deferred tax assets has a greater than 50 percent likelihood of being realized, we are required in that period to reduce the related valuation allowance with a corresponding decrease in income tax expense. This will result in a non-cash benefit to our net income in the period of the determination. In the future, if available evidence changes our conclusion that it is more likely than not that we will utilize our net deferred tax assets prior to their expiration, we will make an adjustment to the related valuation allowance and income tax expense at that time. In the fourth quarter of 2011, we released $325,601 of valuation allowance. In subsequent periods, we would expect to recognize income tax expense equal to our pre-tax income multiplied by our effective income tax rate, an expense that was not recognized prior to the reduction of the valuation allowance.

Net Operating Loss Carry Forwards

As of December 31, 2012, we had NOLs for United States federal and state tax purposes of $744,139 and $290,196, respectively, expiring at various times from years ending 2013 through 2030. In addition, we had NOLs for Canadian tax purposes of $25,476 expiring through 2028. We also had NOLs for United Kingdom tax purposes of $37,765 with no expiration date.

Under Section 382 of the Internal Revenue Code, if we undergo an “ownership change” (generally defined as a greater than 50% change (by value) in our equity ownership over a three-year period), our ability to use our pre-change of control NOLs and other pre-change tax attributes against our post-change income may be limited. The Section 382 limitation is applied annually so as to limit the use of our pre-change NOLs to an amount that generally equals the value of our stock immediately before the ownership change multiplied by a designated federal long-term tax-exempt rate. At December 31, 2012, there were no limitations on the use of our NOLs.

Net Operating Loss Rights Agreement

On June 7, 2012, we entered into a Tax Benefits Preservation Plan ("Preservation Plan") designed to preserve stockholder value and tax assets. In connection with the adoption of the Preservation Plan, our board of directors declared a dividend of one preferred share purchase right for each outstanding share of the Company’s common stock. The preferred share purchase rights were distributed to stockholders of record as of June 18, 2012, as well as to holders of the Company's common stock issued after that date, but will only be activated if certain triggering events under the Preservation Plan occur.

Under the Preservation Plan, preferred share purchase rights will work to impose significant dilution upon any person or group which acquires beneficial ownership of 4.9% or more of the outstanding common stock, without the approval of our board of directors, from and after June 7, 2012. Stockholders that own 4.9% or more of the outstanding common stock as of the opening of business on June 7, 2012 will not trigger the preferred share purchase rights so long as they do not (i) acquire additional shares of common stock or (ii) fall under 4.9% ownership of common stock and then re-acquire shares that in the aggregate equal 4.9% or more of the common stock.

The Preservation Plan was set to expire no later than the close of business June 7, 2013, unless extended by our board of directors. On April 4, 2013, after consultation with our advisors, our board of directors determined to extend the Preservation Plan through June 7, 2015, subject to ratification of the extension by stockholders at our 2013 annual meeting of stockholders. On June 6, 2013, at our 2013 annual meeting of stockholders, stockholders ratified the extension of the Preservation Plan through June 7, 2015.

Share-Based Compensation

We account for share-based compensation in accordance with FASB ASC 718, “Compensation-Stock Compensation”. Under the fair value recognition provisions of this pronouncement, share-based compensation cost is measured at the grant date based on the fair value of the award, reduced as appropriate based on estimated forfeitures, and is recognized as expense over the applicable vesting period of the stock award using the accelerated method.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to financial market risks, including changes in currency exchange rates and interest rates.

Foreign Exchange Risk

We sell our products and services in the United States, Canada, and the United Kingdom. Changes in currency exchange rates affect the valuation in our financial statements of the assets and liabilities of these operations. We also have a portion of our

40

sales denominated in Euros, the Canadian dollar, and the British Pound, which are also affected by changes in currency exchange rates. Our financial results could be affected by changes in foreign currency exchange rates, although foreign exchange risks have not been material to our financial position or results of operations to date.

Interest Rate and Debt Risk

Our exposure to market risk for changes in interest rates primarily relates to our long-term debt.

On February 11, 2013, we entered into Amendment No. 1 to the 2011 Credit Agreement. We are exposed to interest rate risk since amounts payable under the 2013 Credit Facility, at our option, bear interest at:

• LIBOR (applicable to one-, two-, three- or six-month periods) plus an applicable margin equal to 3.125% if our consolidated leverage ratio is less than 0.75 to 1.00, 3.375% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 3.625% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last day of each relevant interest period or, if the interest period is longer than three months, each day that is three months after the first day of the interest period, or

• the base rate determined by reference to the highest of (a) the federal funds effective rate from time to time plus 0.50%, (b) the prime rate of JPMorgan Chase Bank, N.A., and (c) the LIBOR rate applicable to one month interest periods plus 1.00%, plus an applicable margin equal to 2.125% if our consolidated leverage ratio is less than 0.75 to 1.00, 2.275% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 2.625% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last business day of each March, June, September, and December and the maturity date of the 2013 Credit Facility.

If the interest rate on our variable rate debt changed by 1%, our annual debt service payment would change by approximately $600.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Based on the evaluation of our disclosure controls and procedures (as defined in Securities Exchange Act of 1934 Rules 13a-15(e) and 15d-15(e)) required by Securities Exchange Act Rules 13a-15(b) or 15d-15(b), our Chief Executive Officer and our Chief Financial Officer have concluded that as of the end of the period covered by this report, our disclosure controls and procedures were effective.

Changes in Internal Controls. There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(1) including 90 shares, or $246, of common stock repurchases settled in June 2013; excluding commission of 2.

(2) including 220 shares, or $625, of common stock repurchases settled in July 2013; excluding commission of 4.

On February 7, 2013, Vonage's Board of Directors discontinued the remainder of the $50,000 repurchase program, which was announced on July 25, 2012, effective at the close of business on February 12, 2013, with $16,682 remaining, and authorized a new program to repurchase up to $100,000 of the Company's outstanding shares. The $100,000 repurchase program expires on December 31, 2014 but may be suspended or discontinued at any time without notice. The specific timing and amount of repurchases will vary based on available capital resources and other financial and operational performance, market conditions, securities law limitations, and other factors. The repurchases will be made using our cash resources. In any period, cash used in financing activities related to common stock repurchases may differ from the comparable change in stockholders' equity, reflecting timing differences between the recognition of share repurchase transactions and their settlement for cash.

During the three months endedJune 30, 2013, we repurchased 4,756 shares of Vonage Holdings Corp. common stock for $13,452 using cash resources pursuant to the $100,000 repurchase program. The repurchases occurred in the open market and pursuant to a trading plan under Rule 10b5-1 of the Securities Exchange Act of 1934. As of June 30, 2013, approximately $75,542 remained of our $100,000 repurchase program.

EX-10.1

EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (“Agreement”), is entered into this April 25, 2013, by and between VONAGE HOLDINGS CORP., a Delaware corporation (the “Company”), and David T. Pearson (the “Executive”).

NOW, THEREFORE, in consideration of the covenants and agreements hereinafter set forth, the parties hereto agree as follows:

1. Employment and Duties.

(a)General. The Executive shall serve as Chief Financial Officer and Treasurer of the Company, reporting to the Chief Executive Officer (the “CEO”) of the Company and, as requested by the Board of Directors of the Company (the “Board”), to the Board. The Executive shall have the duties, responsibilities, and authority customarily held by the chief financial officer and treasurer of a public corporation. The Executive shall also perform such other duties (which may be increased or decreased at the discretion of the CEO from time to time) as the CEO or Board may from time to time require, which shall be consistent with the general level and type of duties and responsibilities customarily associated with the positions of chief financial officer and treasurer (“Other Duties”). Other Duties may include, without limitation, investor relations, strategic planning and corporate development, and facilities. The Executive’s principal place of employment shall be the principal offices of the Company, currently located in the Holmdel, New Jersey area; provided, however, that the Executive understands and agrees that he shall be required to travel from time to time for business reasons.

(b)Exclusive Services. For so long as the Executive is employed by the Company, the Executive shall devote his full-time working time to his duties hereunder, shall conform to and use his good faith efforts to comply with the lawful and good faith directions and instructions given to him by the CEO and, upon its request, the Board, and shall use his good faith efforts to promote and serve the interests of the Company. Further, the Executive shall not, directly or indirectly, render services to any other person or organization without the consent of the Company or otherwise engage in activities that would interfere with the faithful performance of his duties hereunder. Notwithstanding the foregoing, the Executive may (i) serve on corporate boards, with the prior consent of the CEO, the Chairman of the Board and the Lead Independent Director of the Board, (ii) serve on civic or charitable boards or engage in charitable activities without remuneration therefor, and (iii) manage his personal investments, and serve as an executor, trustee, or in a similar fiduciary capacity in connection therewith, provided that such activities do not, individually or in the aggregate, conflict materially with the performance of the Executive’s duties under this Agreement.

2.Employment “At-Will”. The Executive’s employment shall commence on May 1, 2013 (the “Effective Date”) and the period from the Effective Date through the date of the Executive’s termination of employment, as provided herein, shall be the “Term.” Continuation of the Executive’s employment with the Company throughout the Term shall be deemed an employment “at will” and the Executive’s employment may be terminated “at will” by either Executive or the Company.

3.Compensation and Other Benefits. Subject to the provisions of this Agreement, the Company shall pay and provide the following compensation and other benefits to the Executive during the Term as compensation for services rendered hereunder:

(a)Base Salary. The Company shall pay to the Executive an annual base salary (the “Base Salary”) of not less than Four Hundred Seventy-Five Thousand Dollars ($475,000), payable in substantially equal installments at such intervals as may be determined by the Company in accordance with its regular payroll practices for similarly situated employees, but in no event less

1

frequently than biweekly in arrears. The Base Salary shall be reviewed for increase by the Compensation Committee of the Board in good faith, based upon the Executive’s performance, not less often than annually. The Base Salary may be increased, but not decreased below its then current level, from time to time by the Board, and as so increased shall thereafter be the “Base Salary.”

(b) Sign-On Option Grant and Future Option Grant Opportunities. In connection with the Executive’s commencement of employment, the Executive shall be awarded, on May 3, 2013 (the “Grant Date”), a one-time sign-on nonqualified stock option grant to purchase Two Million (2,000,000) shares of the Company’s common stock  (the number of shares and exercise price being subject to adjustment based on stock splits, reverse stock splits, other adjustments, or recapitalizations between the date hereof and the Grant Date) (the “Sign-OnOptions”) at a price per share equal to the closing price of the Company’s common stock on the Grant Date. The Sign-On Options shall be issued pursuant to the terms and conditions of the Vonage Holdings Corp. 2006 Incentive Plan, as amended or restated from time to time (the “2006 Incentive Plan”), and the Executive’s individual stock option agreement (the “Stock Option Agreement”), in form substantially similar to that attached hereto as Exhibit A. Notwithstanding anything to the contrary in the 2006 Incentive Plan or any stock option agreement thereunder, the following provisions of this Section 3(b) shall govern the terms of the Sign-On Options (and, solely to the extent specifically provided in this Section 3(b), all other outstanding options issued by the Company to the Executive). The Sign-On Options shall vest and become exercisable as to 1/4^th of the shares on each of the first, second, third and fourth anniversaries of the Grant Date (each, an “OptionVesting Date”), subject to the Executive’s continued employment on the applicable Option Vesting Date; provided, however, that all outstanding Sign-On Options shall become fully vested and exercisable if, after a Change of Control, Executive’s employment is terminated without Cause by the Company, for Good Reason by the Executive, or due to the Executive’s death or “disability” (in each case, as defined below) on or prior to the first anniversary thereof. For purposes of this Agreement, “Change of Control” shall have the meaning set forth in the 2006 Incentive Plan; provided, however, that the acquisition of additional securities of the Company by any Person (as defined in the 2006 Incentive Plan) that, together with its Affiliates (as defined in the 2006 Incentive Plan), currently is the Beneficial Owner (as defined in the 2006 Incentive Plan) of twenty percent (20%) or more of the combined voting power of the Company’s outstanding securities shall not constitute a Change of Control. Upon a termination of the Executive’s employment without Cause by the Company or by the Executive for Good Reason (other than on or prior to the first anniversary of a Change of Control), an additional amount of the outstanding Sign-On Options granted by the Company to the Executive shall become vested and immediately exercisable as of the date of such termination in accordance with the provisions of the immediately following sentence. For each outstanding Sign-On Option, such additional amount shall be equal to the number of Sign-On Options that would have vested on the next Option Vesting Date immediately following the date of termination, multiplied by a fraction where (1) the numerator is the number of full and fractional months that had elapsed between the Option Vesting Date immediately prior to such termination and such termination date plus the number of full and fractional months remaining in the calendar quarter that includes such termination date, and (2) the denominator is twelve (12). Notwithstanding the foregoing, in no event shall the number of Sign-On Options vesting pursuant to the foregoing sentence exceed the number of Sign-On Options that would have vested on the next Option Vesting Date immediately following the date of termination. Upon a termination of the Executive’s employment by the Company without Cause or by the Executive for Good Reason, all outstanding options granted by the Company to the Executive (whether part of the Sign-On Options or not) shall (to the extent vested) remain exercisable for at least 180 days after the termination, or until the end of the term of the option, if earlier. Upon a termination of the Executive’s employment by the Executive without Good Reason, all vested outstanding options granted by the Company to the Executive shall remain exercisable for at least 60 days after termination, or until the end of the term of the option, if earlier. The Executive shall be considered for future option grants based on individual and Company performance (and established in conjunction with the Company’s regular equity review cycle).

2

(c)Annual Cash Bonus. The Executive shall be eligible to receive an annual, discretionary cash bonus (the “Annual Bonus”) with a Target Bonus Opportunity (“TBO”) of up to 100% of the Executive’s then current Base Salary for the applicable year. Subject to Sections 4(b) and 4(c) below, for calendar year 2013, the Annual Bonus for which the Executive is eligible shall be equal to the greater of (i) $475,000 and (ii) the Annual Bonus the Executive otherwise would be eligible to receive in respect of 2013, prorated for the number of full months worked from the Effective Date through December 31, 2013. Annual Bonus payouts are not guaranteed and are granted in the Company’s sole discretion based on individual and Company performance. The Company performance targets applicable to the Executive’s Annual Bonus shall be in accordance with the Company’s annual bonus program as applicable to senior executives of the Company, as in effect from time to time. Annual Bonus payouts, if any, are generally paid in February or March of the calendar year following the calendar year in which such payout is earned, subject to the Executive’s continued employment on such payment date, except as otherwise provided in Section 4.

(d)Employee Benefit Plans.

(i)The Executive shall be entitled to participate in all employee health and welfare plans, programs and arrangements of the Company, in accordance with their respective terms, as may be amended from time to time, on a basis no less favorable than that made available to other senior executives of the Company; provided, however, that, to the extent it does so for the CEO, the Company will pay the full cost of the following insurance benefits for the Executive and his spouse and dependents: medical, dental, vision, basic life, accidental death and dismemberment, and core long term disability. The Executive shall be eligible to participate in the Vonage medical and dental plans and the 401(k) Retirement Plan commencing on the first day of the month following the Effective Date.

(ii)The Company shall reimburse the Executive for all reasonable out-of-pocket expenses actually incurred or paid by the Executive for the continuation of the Executive’s current medical and dental benefits for the Executive and his spouse and dependents (and excluding all other benefits, including, without limitation, vision benefits) during the waiting period described in Section 3(d)(i) above, in the amount of 100% of such costs up to a maximum of $4,000.

(e)Expenses. The Company shall reimburse the Executive for reasonable travel and other business-related expenses incurred by the Executive in the fulfillment of his duties hereunder upon presentation of written documentation thereof, in accordance with the applicable expense reimbursement policies and procedures of the Company as in effect from time to time.

(f)Vacation. The Executive shall be entitled to 20 days paid time off in accordance with the Company’s vacation policy (but which shall not be prorated for 2013) during each fiscal year of the Term, which may be carried over to the next fiscal year of the Term to the extent otherwise permitted under the Company’s vacation policy.

(g)Legal Fees. Upon presentation of appropriate documentation, the Company shall pay the Executive’s reasonable counsel fees incurred in connection with the negotiation and documentation of this Agreement, up to a maximum of $15,000.

(h)Other Benefits and Perquisites. The Executive shall be entitled to such other benefits and perquisites as may be available generally to other senior executives of the Company.

4. Termination of Employment.

(a)Termination for Cause; Resignation without Good Reason.

3

(i)    If the Company terminates the Executive’s employment for Cause, or if the Executive resigns from his employment hereunder other than for Good Reason, the Executive shall only be entitled to payment of any unpaid Base Salary through and including the date of termination or resignation, any unpaid expense reimbursement , any accrued but unused vacation, and any other amounts or benefits required to be paid under this Agreement through the date of termination or resignation, including but not limited to those under Sections 3(e), 3(g), and 3(h) hereof (in each case only to the extent earned or accrued prior to such date of termination or resignation , or provided by law or under any plan, program, policy or practice of the Company (the “Other Accrued Compensation and Benefits”). The Executive shall have no further right under this Agreement to receive any other compensation or benefits after such termination or resignation of employment.

(ii)    For purposes of this Agreement, “Cause” shall mean: (A) any act or omission that constitutes a material breach by the Executive of his obligations under this Agreement; (B) the willful and continued failure or refusal of the Executive (not as a consequence of illness, accident or other incapacity) to perform the duties reasonably required of him hereunder; (C) the Executive’s conviction of, or plea of nolo contendere to, (x) any felony or (y) another willful crime involving dishonesty or moral turpitude or which reflects negatively upon the Company and/or its subsidiaries or affiliates (collectively, the “Company Group”) in a material manner or otherwise materially impairs or impedes the operations of the Company Group; (D) the Executive’s engaging in any willful misconduct, gross negligence or act of dishonesty with regard to the Company Group or his material duties, which conduct is injurious to the Company Group; (E) the Executive’s material breach of either a material written policy of the Company Group or, to the extent the Executive is aware of such rules or has been informed by the Company’s counsel, the relevant rules of any governmental or regulatory body applicable to the Company Group; or (F) the Executive’s refusal to follow the lawful directions of the Board; provided, however, that no event or condition described in clauses (A), (B), (E) or (F) shall constitute Cause unless (i) the Company first gives the Executive written notice of its intention to terminate his employment for Cause and the grounds for such termination, and (ii) such grounds for termination (if susceptible to correction) are not corrected by the Executive within thirty (30) days of his receipt of such notice (or, in the event that such grounds cannot be corrected within such thirty (30) day period, the Executive has not taken all reasonable steps within such thirty (30) day period to correct such grounds as promptly as practicable thereafter).

(iii)    For purposes of this Agreement, “Good Reason” shall mean the occurrence of any of the following events without the Executive’s prior written consent: (A) a failure by the Company to timely pay material compensation due and payable to the Executive in connection with his employment; (B) a material diminution in the Executive’s Base Salary or TBO; (C) a material diminution of the authority, duties or responsibilities of the Executive from those set forth in this Agreement (excluding the Other Duties), including without limitation, ceasing to be the Chief Financial Officer and Treasurer of the Company (or its ultimate parent following a Change of Control); (D) the Company requiring the Executive to be based at any office or location more than fifty (50) miles from the Holmdel, New Jersey area; or (E) a material breach by the Company of its obligations under this Agreement; provided, however, that no event or condition described in clauses (A) through (E) shall constitute Good Reason unless (x) the Executive gives the Company within sixty (60) days of the occurrence of the Good Reason event, written notice of his intention to terminate his employment for Good Reason and the grounds for such termination, and (y) such grounds for termination (if susceptible to correction) are not corrected by the Company within thirty (30) days of its receipt of such notice (or, in the event that such grounds cannot be corrected within such thirty (30) day period, the Company has not taken all reasonable steps within such thirty (30) day period to correct such grounds as promptly as practicable thereafter). Such termination for Good Reason by the Executive must occur within 120 days of the occurrence of the Good Reason event.

(b)Termination without Cause; Resignation for Good Reason.

4

(i)    If the Executive’s employment is terminated by the Company without Cause or the Executive resigns for Good Reason, the Company shall pay the Executive, subject to Section 4(e) below: (A) severance pay equal to twelve (12) months of the Executive’s then-current Base Salary and an amount equal to the Executive’s full TBO for the year of termination payable by the Company in installments during its regular payroll cycle over the twelve (12) month period following the Executive’s termination of employment, provided that the first payment shall be made on the sixtieth (60^th) day after the Executive’s termination of employment, and such first payment shall include payment of any amounts that would otherwise be due prior thereto, (B) a pro rata portion of the Executive’s Annual Bonus for the year of termination, if and to the extent that the Company achieves its performance metrics for such year, payable when bonuses are normally paid to other senior executives of the Company, but in no event later than March 15th of the year following the year to which such bonus relates, and (C) the Other Accrued Compensation and Benefits. The Executive shall have no further rights under this Agreement to receive any other compensation or benefits after such termination or resignation of employment.

(ii)    If, following a termination of employment without Cause or a resignation for Good Reason, the Executive materially breaches a provision of Section 5, Section 6 or Section 7 hereof, the Executive shall not be eligible, as of the date of such material breach, for the payments and benefits described in Sections 4(b)(i)(A) or (B) and any and all obligations and agreements of the Company with respect to such payments shall thereupon cease.

(c)Termination Due to Death or Disability. The Executive’s employment with the Company shall terminate automatically on the Executive’s death. In the event of the Executive’s disability, the Company shall be entitled to terminate his employment. In the event of termination of the Executive’s employment by reason of the Executive’s death or disability, the Company shall pay to the Executive (or his estate, as applicable), subject to Section 4(e) below, (i) a pro rata portion of the Executive’s Annual Bonus for the year of termination, if and to the extent that the Company achieves its performance metrics for such year, payable when bonuses are normally paid to other senior executives of the Company, but in no event later than March 15th of the year following the year to which such bonus relates, and (ii) the Other Accrued Compensation and Benefits. For purposes of this Agreement, “disability” means that the Executive has been unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment for 180 days in any one (1) year period. Notwithstanding the foregoing, in the event that as a result of absence because of mental or physical incapacity the Executive incurs a “separation from service” within the meaning of such term under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations and guidance issued thereunder (“Section 409A”), the Executive shall on such date automatically be terminated from employment as a disability termination.

(d)Release and Waiver. The Company shall not be required to make the payments and provide the benefits provided for under Sections 4(b)(i)(A) or (B) or, in the case of a disability termination, Section 4(c)(i), unless the Executive (or, if applicable in the case of a disability termination, the person having legal power of attorney over his affairs) executes and delivers to the Company a Separation Agreement and General Release in substantially the form attached hereto as Exhibit B (the “Release”), and such Release has become effective and irrevocable in its entirety within sixty (60) days of the Executive’s termination of employment.

(e)Payments Subject to Section 409A.

(i)    The intent of the parties is that payments and benefits under this Agreement comply with Section 409A (except to the extent exempt as short-term deferrals or otherwise) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. If the Executive notifies the Company (with specificity as to the reason therefor)

5

that the Executive believes that any provision of this Agreement (or of any award of compensation, including equity compensation or benefits) would cause the Executive to incur any additional tax or interest under Section 409A or the Company independently makes such determination, the Company shall, after consulting with the Executive, reform such provision to attempt to comply with Section 409A through good faith modifications to the minimum extent reasonably appropriate to conform with Section 409A. To the extent that any provision hereof is modified in order to comply with Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Executive and the Company of the applicable provision without violating the provisions of Section 409A. If the Executive notifies the Company (with specificity as to the reason therefor) that the Executive believes that any of the Company’s plans, programs or payroll practices would cause the Executive to incur any additional tax or interest under Section 409A, the Company shall in good faith discuss with the Executive any proposed modifications to such plans, programs or payroll practices that are reasonably necessary to comply with Section 409A. Nothing contained herein shall constitute any representation or warranty by the Company regarding compliance with Section 409A and, notwithstanding anything else to the contrary herein, the members of the Company Group, and each of their respective employees or representatives, shall have no liability to the Executive with respect to the assessment of any additional income tax, interest or penalties under Section 409A.

(ii)    A termination of employment shall not be deemed to have occurred for purposes of this Agreement providing for the payment of any amounts or benefits that are considered “nonqualified deferred compensation” under Section 409A upon or following a termination of employment, unless such termination is also a “separation from service” from the Company within the meaning of Section 409A and the payment thereof prior to a “separation from service” from the Company would violate Section 409A. As permitted by Treasury Regulation 1.409A-1(h)(1)(ii), 49% shall be substituted in lieu of 20% for the average level of bona fide services performed during the immediately preceding thirty-six (36) month period in order to constitute a “separation from service”. For purposes of any provision of this Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” Solely for purposes of this Section 4(e)(ii), “Company” shall include all persons with whom the Company would be considered a single employer under Sections 414(b) and 414(c) of the Code.

(iii)    For purposes of Section 409A, the Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within thirty (30) days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company.

(iv)    If, as of the date of the “separation from service” of the Executive from the Company, the Executive is a “specified employee” (within the meaning of that term under Section 409A(a)(2)(B)), then with regard to any payment or the provision of any benefit that is specified herein as subject to this Section or is otherwise considered “nonqualified deferred compensation” under Section 409A (whether under this Agreement, any other plan, program, payroll practice or any equity grant) and is payable upon the Executive’s separation from service, such payment or benefit shall not be made or provided until the date which is the earlier of (A) the expiration of the six (6)-month-and-one-day period measured from the date of such “separation from service” of the Executive, and (B) the date of the Executive’s death (the “Delay Period”) and this Agreement and each such plan, program, payroll practice or equity grant shall hereby be deemed amended accordingly. Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum with interest at the prime rate as published in the Wall Street Journal on the first business day of the Delay Period (provided that any payment measured by a change in value that continues during

6

the Delay Period shall not be credited with interest for the Delay Period), and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(v)    All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A. All expenses or other reimbursements paid pursuant hereto that are taxable income to the Executive shall in no event be paid later than the end of the calendar year next following the calendar year in which the Executive incurs such expense or pays such related tax. With regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Section 409A, the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, the amount of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year, provided that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect and such payments shall be made on or before the last day of the Executive’s taxable year following the taxable year in which the expense occurred.

(f)Notice of Termination. Any termination of employment by the Company or the Executive shall be communicated by a written “Notice of Termination” to the other party hereto given in accordance with Section 21 of this Agreement.

(i)By Company. In the event of a termination by the Company for Cause, the Notice of Termination shall (A) indicate the specific termination provision in this Agreement relied upon, (B) set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated and (C) indicate the date on which such termination is effective (subject to applicable correction periods). The failure by the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause shall not waive any right of the Company hereunder or preclude the Company from asserting such fact or circumstance in enforcing the Company’s rights hereunder to the extent that such fact or circumstance is on the same asserted basis within the definition for the termination. In the event of a termination by the Company without Cause, the Notice of Termination shall specify the date of termination, which date shall not be more than thirty (30) days after the giving of such notice.

(ii)By Executive. In the event of a resignation by the Executive for Good Reason, the Notice of Termination shall (A) indicate the specific termination provision in this Agreement relied upon, (B) set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated and (C) specify the date of termination, which date shall not be more than thirty (30) days after the giving of such notice. In the event of a resignation by the Executive other than for Good Reason, the Notice of Termination shall specify the date of termination, which date shall not be less than thirty (30) days after the giving of such notice. The failure by the Executive to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason shall not waive any right of the Executive hereunder or preclude the Executive from asserting such fact or circumstance in enforcing the Executive’s rights hereunder to the extent that such fact or circumstance is on the same asserted basis within the definition for the termination. In the event of a termination by the Executive without Good Reason, the Notice of Termination shall specify the date of termination, which date shall not be more than thirty (30) days after the giving of such notice.

7

(g)Resignation from Directorships and Officerships. The termination of the Executive’s employment for any reason shall constitute the Executive’s resignation from (i) any director, officer, or employee position the Executive has with members of the Company Group, and (ii) all fiduciary positions (including as a trustee) the Executive holds with respect to any employee benefit plans or trusts established by any members of the Company Group. The Executive agrees that this Agreement shall serve as written notice of resignation in this circumstance.

5. Confidentiality.

(a)Confidential Information. The Executive has entered into and is subject to the Company’s Employee Confidentiality and Innovations Agreement substantially in the form attached hereto as Exhibit C.

(b)Exclusive Property. The Executive confirms that all Confidential Information (as defined in the Employee Confidentiality and Innovations Agreement) is and shall remain the exclusive property of the Company Group. All business records, papers and documents kept or made by the Executive relating to the business of the Company Group shall be and remain the property of the Company Group. Upon the request and at the expense of the Company Group, the Executive shall promptly make all disclosures, execute all instruments and papers, and perform all acts reasonably necessary to vest and confirm in the Company Group, fully and completely, all rights created or contemplated by this Section 5(b). Notwithstanding the foregoing, the Executive shall maintain ownership and use of his rolodex and other address books.

6.Noncompetition. The Executive has entered into and is subject to the Company’s Non-Compete Agreement substantially in the form attached hereto as Exhibit D.

7.Non-Solicitation and Non-Hire. The Executive has agreed and now confirms that for a period commencing on the Effective Date and ending twelve (12) months following the Executive’s termination of employment with the Company (the “Restricted Period”), other than in the good faith performance of his duties to the Company as Chief Financial Officer and Treasurer of the Company, the Executive shall not, directly or indirectly: (a) interfere with or attempt to interfere with the relationship between any person who is, or was during the then-most recent twelve (12) month period, an employee, officer, representative or agent of any member of the Company Group, or solicit or induce or attempt to solicit or induce any of them to leave the employ of any member of the Company Group or violate the terms of their respective contracts, or any employment arrangements, with any such entities; or (b) hire, recruit or attempt to hire any person who was employed by any member of the Company Group at any time during the then-most recent twelve (12) month period; provided, that this clause (b) shall not apply to the recruitment or hiring of any individual whose employment with any member of the Company Group has been terminated for a period of six (6) months or longer; or (c) induce or attempt to induce any customer, client, supplier, licensee or other business relation of any member of the Company Group to cease doing business with any member of the Company Group, or in any way interfere with the relationship between any member of the Company Group and any customer, client, supplier, licensee or other business relation of any member of the Company Group. Nothing in this Section 7 shall be violated by the Executive serving upon request as a reference, so long as he does not have a business relationship with the person to whom the reference is being given, and nothing in this Section 7 shall be violated by the Executive engaging in general advertising that is not specifically targeted at the persons referred to in clauses (a), (b) and (c) that have a relationship with a member of the Company Group. As used herein, the term “indirectly” shall include, without limitation, the Executive’s authorizing the use of the Executive’s name by any competitor of any member of the Company Group to induce or interfere with any employee or business relationship of any member of the Company Group.

8.Certain Remedies.

(a)Injunctive Relief. Without intending to limit the remedies available to either party hereto, including, but not limited to, those set forth in Section 11 hereof, each of the parties hereto agrees that a breach of any of the covenants contained in Sections 5, 6, or 7 of this Agreement may result in material and irreparable injury to the other party for which there is no adequate remedy at law, that it shall not be possible to measure damages for such injuries precisely and that, in the event of such a breach or threat thereof, any non-breaching party shall be entitled to seek a temporary restraining order or a preliminary or permanent injunction, or both, without bond or other security, restraining the breaching party from engaging in activities prohibited by the covenants contained in Sections 5, 6 or 7 of this Agreement or such other relief as may be required specifically to enforce any of the covenants contained in this Agreement. Such injunctive relief in any court shall be available to the non-breaching party in lieu of, or prior to or pending determination in, any arbitration proceeding.

(b)Extension of Restricted Period. In addition to the remedies the Company may seek and obtain pursuant to Section 11 hereof, the Restricted Period may, in the court’s discretion, be extended by any and all periods during which the Executive shall be found by a court possessing personal jurisdiction over him to have been in violation of the covenants contained in Sections 5 through 7 of this Agreement.

9.Defense of Claims. The Executive agrees that, during the Term, and for a period of six (6) months after termination of the Executive’s employment, upon request from the Company, the Executive shall cooperate with the Company in connection with any matters the Executive worked on during his employment with the Company and any related transitional matters. In addition, the Executive agrees to cooperate with any member of the Company Group in the defense of any claims or actions that are made and/or may be made by or against any member of the Company Group, except if the Executive’s reasonable interests are adverse to the Company Group in such claim or action. The Company agrees to promptly reimburse the Executive for all of the Executive’s reasonable travel and other direct expenses incurred, or to be reasonably incurred, to comply with the Executive’s obligations under this Section 9.

10.Source of Payments. All payments provided under this Agreement, other than payments made pursuant to a plan which provides otherwise, shall be paid in cash from the general funds of the Company, and no special or separate fund shall be established, and no other segregation of assets shall be made, to assure payment. The Executive shall have no right, title or interest whatsoever in or to any investments which the Company may make to aid the Company in meeting its obligations hereunder. To the extent that any person acquires a right to receive payments from the Company hereunder, such right shall be no greater than the right of an unsecured creditor of the Company.

11.Arbitration. Any dispute or controversy arising under or in connection with this Agreement or otherwise in connection with the Executive’s employment by the Company that cannot be mutually resolved by the parties to this Agreement and their respective advisors and representatives shall be settled exclusively by arbitration in New Jersey in accordance with the rules of the American Arbitration Association before one arbitrator of exemplary qualifications and stature, who shall be selected jointly by an individual to be designated by the Company and an individual to be selected by the Executive, or if such two individuals cannot promptly agree on the selection of the arbitrator, who shall be selected by the American Arbitration Association. The award of the arbitrator with respect to such dispute or controversy shall be in writing with sufficient explanation to allow for such meaningful judicial review as is permitted by law, and that such decision shall be enforceable in any court of competent jurisdiction and shall be binding on the parties hereto. The remedies available in arbitration shall be identical to those allowed at law. The arbitrator shall be entitled to award to the prevailing party in any arbitration or judicial action under this Agreement reasonable attorneys’ fees and any costs of the arbitration payable by such party, consistent with applicable law; provided, that no such award shall be made against the Executive unless the arbitrator finds the Executive’s positions in such arbitration or dispute to have been frivolous or in bad faith.

12.Nonassignability; Binding Agreement.

(a)By the Executive. This Agreement and any and all of the Executive’s rights, duties, obligations or interests hereunder shall not be assignable or delegable by the Executive.

(b)By the Company. This Agreement and any and all of the Company’s rights, duties, obligations or interests hereunder shall not be assignable by the Company, except as incident to a reorganization, merger or consolidation, or transfer of all or substantially all of the Company’s assets and then only if the Company’s obligations hereunder are assumed by the assignee.

(c)Binding Effect. This Agreement shall be binding upon, and inure to the benefit of, the parties hereto, any successors to or permitted assigns of the Company, and the Executive’s heirs and the personal representatives of the Executive’s estate.

13.Withholding. Any payments made or benefits provided to the Executive under this Agreement shall be reduced by any applicable withholding taxes or other amounts required to be withheld by law or contract.

14.Certain Payments.

(a)Modified Cutback. If any payment, benefit or distribution of any type to or for the benefit of the Executive, whether paid or payable, provided or to be provided, or distributed or distributable pursuant to the terms of this Agreement or otherwise (collectively, the “Parachute Payments”) would subject the Executive to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), the Parachute Payments shall be reduced so that the maximum amount of the Parachute Payments (after reduction) shall be one dollar ($1.00) less than the amount which would cause the Parachute Payments to be subject to the Excise Tax; provided, that the Parachute Payments shall only be reduced to the extent the after-tax value of amounts received by the Executive after application of the above reduction would exceed the after-tax value of the amounts received without application of such reduction. For this purpose, the after-tax value of an amount shall be determined taking into account all Federal, state, and local income, employment and excise taxes applicable to such amount. If a reduction in the Parachute Payments is required hereunder, the Company shall reduce or eliminate the Parachute Payments by first reducing or eliminating any cash severance benefits (with the payments to be made furthest in the future being reduced first), then by reducing or eliminating any accelerated vesting of stock options or similar awards, then by reducing or eliminating any accelerated vesting of restricted stock or similar awards, then by reducing or eliminating any other remaining Parachute Payments; provided, that no such reduction or elimination shall apply to any non-qualified deferred compensation amounts (within the meaning of Section 409A) to the extent such reduction or elimination would accelerate or defer the timing of such payment in manner that does not comply with Section 409A.

(b)Determinations. An initial determination as to whether (i) any of the Parachute Payments received by the Executive in connection with the occurrence of a change in the ownership or control of the Company or in the ownership of a substantial portion of the assets of the Company shall be subject to the Excise Tax, and (ii) the amount of any reduction, if any, that may be required pursuant to subsection (a) above, shall be made by an independent accounting firm selected by the Company and reasonably acceptable to Executive (the “Accounting Firm”) prior to the consummation of such change in the ownership or effective control of the Company or in the ownership of a substantial portion of the assets of the Company. The Executive shall be furnished with notice of all determinations made as to the Excise Tax potentially payable with respect to the Executive’s Parachute Payments, together with the related calculations of the Accounting Firm, promptly after such determinations and calculations have been received by the Company.

10

15.Amendment; Waiver. This Agreement may not be modified, amended or waived in any manner, except by an instrument in writing signed by both parties hereto. The waiver by either party of compliance with any provision of this Agreement by the other party shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by such party of a provision of this Agreement.

16.Governing Law. All matters affecting this Agreement, including the validity thereof, are to be governed by, and interpreted and construed in accordance with, the laws of the State of New Jersey applicable to contracts executed in and to be performed in that State.

17.Survival of Certain Provisions. The rights and obligations set forth in Section 3(b), Sections 4 through 11, and 14 hereof shall survive any termination or expiration of this Agreement.

18.Entire Agreement; Supersedes Previous Agreements. This Agreement, together with the (i) Employee Confidentiality and Innovations Agreement, (ii) Non-Compete Agreement, (iii) 2006 Incentive Plan, (iv) Stock Option Agreement, and (v) the Indemnification Agreement, dated as of April 25, 2013, between the Company and the Executive, each as amended from time to time, contains the entire agreement and understanding of the parties hereto with respect to the matters covered herein and supersedes all prior or contemporaneous negotiations, commitments, agreements and writings with respect to the subject matter hereof, including, without limitation, the cover letter and employment agreement term sheet dated as of March 12, 2013. All such other negotiations, commitments, agreements and writings shall have no further force or effect, and the parties to any such other negotiation, commitment, agreement or writing shall have no further rights or obligations thereunder.

19.Counterparts. This Agreement may be executed by either of the parties hereto in counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

20.Headings. The headings of sections herein are included solely for convenience of reference and shall not control the meaning or interpretation of any of the provisions of this Agreement.

2006 INCENTIVE PLAN

NONQUALIFIED STOCK OPTION AGREEMENT

“Participant”: David T. Pearson

“Date of Award”: May 3, 2013

This Agreement (the “Agreement”), effective as of the Date of Award set forth above, represents the grant of Nonqualified Stock Options by Vonage Holdings Corp., a Delaware corporation (the ”Company”), to the Participant named above, pursuant to the provisions of the Vonage Holdings Corp. 2006 Incentive Plan, as amended or restated from time to time, (the ”Plan”). Capitalized terms have the meanings ascribed to them under the Plan, unless specifically set forth herein.

The parties hereto agree as follows:

1. Grant of Options

(b)To the extent not previously vested in accordance with this Section 2, in the event the Participant’s employment is terminated without Cause by the Company, for Good Reason by the Participant, or due to the Participant’s death or disability, in each case, on or prior to the first (1st) anniversary of a Change of Control (which, for purposes of this Agreement, shall have the meaning set forth in Section 3(b) (or any successor section thereto) of that certain Employment Agreement, dated as of April 25, 2013, by and between the Company and the Participant, as such agreement may be amended from time to time (the “Employment Agreement”)), the Options will fully vest and become exercisable upon such termination of employment.

US_ACTIVE:\44218152\7\79143.0003

termination in accordance with the provisions of the immediately following sentence and (ii) remain exercisable until they terminate in accordance with Section 4 below. For each outstanding Option, such additional amount shall be equal to the number of Options that would have vested on the next Vesting Date immediately following the date of termination, multiplied by a fraction where (1) the numerator is the number of full and fractional months that had elapsed between the Vesting Date immediately prior to such termination and such termination date plus the number of full and fractional months remaining in the calendar quarter that includes such termination date, and (2) the denominator is 12. Notwithstanding the foregoing, in no event shall the number of Options vesting pursuant to this Section 2(c) exceed the number of Options that would have vested on the next Vesting Date immediately following the date of termination.

(d)    To the extent not previously vested in accordance with this Section 2, in the event of the Participant’s death (other than on or prior to the first (1st) anniversary of a Change of Control), the Options will (i) vest and become exercisable as of the date thereof as to one-half the number of unvested Shares covered thereby and (ii) remain exercisable until they terminate in accordance with Section 4 below.

(e)    To the extent not previously vested in accordance with this Section 2, in the event of the Participant’s disability (other than on or prior to the first (1st) anniversary of a Change of Control), the Options will (i) vest and become exercisable as of the date thereof as to one-half the number of unvested Shares covered thereby and (ii) remain exercisable until they terminate in accordance with Section 4 below.

(f)     Notwithstanding anything to the contrary herein, if the Participant’s employment with the Company is terminated by the Company with Cause, the Options will terminate immediately and be of no force or effect.

(g)    To the extent vested in accordance with this Section 2, the Options will remain exercisable until they terminate in accordance with Section 4 below.

(i)    For purposes of this Section 2, the terms “Cause,” “Good Reason” and “disability” shall have the respective meanings ascribed to them in the Employment Agreement.

3. Exercise of Options

The Options may be exercised by any means specified in Section 7(d) of the Plan, as well as by a broker cashless exercise procedure, all of which the Committee hereby approves.

4. Termination of Options

To the extent vested in accordance with Section 2 above, the Options will terminate, and be of no force or effect, upon the earliest of:

(a)the date of termination of the Participant’s employment if such termination of employment is for Cause,

(b)180 days following termination of Participant’s employment by the Company without Cause or by the Participant for Good Reason,

(c)60 days following termination of Participant’s employment due to the Participant’s resignation without Good Reason, and

US_ACTIVE:\44218152\7\79143.0003

5. Rights as Stockholder

The Participant shall have no rights as a stockholder of the Company with respect to the Shares covered by the Options until such time as the Option Price has been paid and the Shares have been issued and delivered to the Participant.

6. Transferability

Unless permitted by the Committee in accordance with the terms of the Plan, the Options may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution, and, during the Participant’s lifetime, may be exercised only by the Participant or in the event of the Participant’s legal incapacity, the Participant’s legal guardian or representative.

7. Miscellaneous

(a)This Agreement and the rights of the Participant hereunder are subject to the terms and conditions of the Plan, as the same may be amended from time to time, as well as to such rules and regulations as the Committee may adopt for administration of the Plan. If there is any inconsistency between the terms of this Agreement and the terms of the Plan, the Plan’s terms shall completely supersede and replace the conflicting terms of this Agreement.

(b)This Agreement shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required or, the Committee determines are advisable. The Participant agrees to take all steps the Company determines are necessary to comply with all applicable provisions of federal and state securities law in exercising his rights under this Agreement. The Committee shall have the right to impose such restrictions on any Shares acquired pursuant to the exercise of the Option as it deems necessary or advisable under applicable federal securities laws, the rules and regulations of any stock exchange or market upon which Shares are then listed or traded, and/or any blue sky or state securities laws applicable to Shares. It is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate to the administration of the Plan and this Agreement, all of which shall be binding upon the Participant.

(c)The Options are intended not to provide for a “deferral of compensation” within the meaning of Section 409A of the Code. Notwithstanding the forgoing or any provision of the Plan or this Agreement, if any provision of this Agreement or the Plan contravenes Section 409A of the Code or could cause the Participant to incur any tax, interest or penalties under Section 409A of the Code, the Committee may, in its sole discretion and without the Participant’s consent, modify such provision in order to comply with the requirements of Section 409A of the Code or to satisfy the conditions of any exception therefrom, or otherwise to avoid the imposition of the additional income tax and interest under Section 409A of the Code, while maintaining, to the maximum extent practicable, the original intent and economic benefit to the Participant, without materially increasing the cost to the Company, of the applicable provision.

(d)Delivery of the Shares underlying the Options upon exercise will be subject to the Participant satisfying all applicable federal, state, local and foreign taxes. The Company shall have authority to deduct or withhold from all amounts payable to the Participant in connection with the Options, or require the Participant to remit to the Company, an amount sufficient to satisfy any applicable taxes required by law. The Participant shall have the right to cover the minimum statutory withholding by directing the Company to withhold Shares that would otherwise be received by him, by utilization of a cashless broker transaction or by any other means permitted by Section 18 of the Plan.

(e)To the extent not preempted by federal law, this Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Separation Agreement and General Release

CONFIDENTIAL SEPARATION AGREEMENT AND GENERAL RELEASE

This CONFIDENTIAL SEPARATION AGREEMENT and GENERAL RELEASE (hereinafter referred to as this “Agreement”) is made and entered into by and between David T. Pearson (“Executive”) and Vonage Holdings Corp. (defined herein to include its affiliates, subsidiaries, predecessors and successors and hereinafter referred to as “Vonage” or “the Company”), effective as of [] (the “Effective Date”). Executive and Vonage are hereafter referred to as the “Parties.”

WHEREAS, Executive was employed by Vonage as its Chief Financial Officer and Treasurer;

WHEREAS, Executive and Vonage entered into an Employment Agreement, dated as of April 25, 2013 (the “Employment Agreement”);

WHEREAS, [description of nature of termination];

WHEREAS, Vonage and Executive have read this Agreement and have had the opportunity to review it with their respective legal counsel; and

WHEREAS, Vonage and Executive desire to resolve any and all issues and claims between them, including without limitation Executive’s employment and his separation therefrom, as well as any and all issues and claims arising from or relating to the Employment Agreement, and to reach an amicable accord and settlement concerning their future relationship.

NOW, THEREFORE, in consideration of the premises and mutual promises herein contained, it is agreed as follows:

1.Separation and Post-Employment Benefits. Executive ceased performing duties for Vonage on [] (the “Termination Date”), and Executive’s services on any and all boards of directors, boards of trustees and executive and/or management committees of Vonage of which he was a member ended on such date. The terms of Executive’s separation from Vonage are now being agreed to, as described herein.

2.Salary. Executive agrees that Vonage has no obligation to make, and will not make, any additional salary payments to Executive that have not already been paid, except for any and all earned, accrued or owed amounts, but not yet paid, to which Executive is entitled up to and including the Termination Date, including any unpaid expense reimbursement , any accrued but unused vacation and any other amounts or benefits required to be paid under the Employment Agreement or provided by law or under any plan, program, policy or practice of Vonage and not including the payments or benefits described in Paragraph 5 below (“Other Accrued Compensation and Benefits”), payable in a lump sum within five (5) days after the revocation period described in Paragraph 18(d) below. Any further entitlement that Executive may have to compensation or benefits, such as the payments and benefits described in Paragraph 5 below, shall be governed by the terms of this Agreement.

3.Non-Admission. It is specifically understood and agreed that this Agreement does not constitute and is not to be construed as an admission or evidence of (a) any violation by Vonage or Executive, of any federal, state or municipal law, statute or regulation, or principle of common law or equity, (b) the commission by Executive or Vonage of any other actionable wrong, or (c) any wrongdoing of any kind whatsoever on the part of Executive or Vonage, and shall not be offered, argued or used for that purpose.

4.General Release.

(a)In exchange for the consideration provided in this Agreement, and as a material inducement for both Parties entering into this Agreement, Executive for himself, his heirs, executors, administrators, trustees, legal representatives, successors and assigns (hereinafter collectively referred to for purposes of this Paragraph 4 as “Executive”) hereby irrevocably and unconditionally waives, releases and forever discharges Vonage and its past, present and future affiliates and related entities, parent and subsidiary corporations, divisions, shareholders, predecessors, future officers, directors, trustees, fiduciaries, administrators, executives, agents, representatives, successors and assigns (hereinafter collectively referred to for purposes of this Paragraph 4 as “Vonage”) for any and all waivable claims, charges, demands, sums of money, actions, rights, promises, agreements, causes of action, obligations and liabilities of any kind or nature whatsoever, at law or in equity, whether known or unknown, existing or contingent, suspected or unsuspected, apparent or concealed, foreign or domestic (hereinafter collectively referred to as “claims”) which he has now or in the future may claim to have against Vonage based upon or arising out of any facts, acts, conduct, omissions, transactions, occurrences, contracts, claims, events, causes, matters or things of any conceivable kind or character existing or occurring or claimed to exist or to have occurred prior to the Effective Date in any way whatsoever relating to or arising out of Executive’s employment with Vonage or the termination thereof. Such claims include, but are not limited to, claims arising under the Age Discrimination in Employment Act, 29 U.S.C. § 621 etseq.; Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e etseq.; the Americans with Disabilities Act of 1990, 42 U.S.C. § 12101 etseq.; the Family and Medical Leave Act of 1993, 29 U.S.C. § 2601 etseq.; the Employee Retirement Income Security Act of 1974, 29 U.S.C. § 1001 etseq.; the Equal Pay Act of 1963, 29 U.S.C. § 206(d); Section 806 of the Corporate and Criminal Fraud Accountability Act of 2002, 18 U.S.C. § 1681 etseq.; the Fair Credit Reporting Act, 15 U.S.C. §1681 etseq.; any other federal, state or local statutory laws relating to employment, discrimination in employment, termination of employment, wages, benefits or otherwise, including, but not limited to, the New Jersey Law Against Discrimination, the Conscientious Employee Protection Act, the New Jersey Wage Payment Law, the New Jersey Family Leave Act, all as amended; the common law of the State of New Jersey; any claim under any local ordinance, including, but not limited to, any ordinance addressing fair employment practices; any claims for employment or reemployment by the Company; any common law claims, including but not limited to actions in tort, defamation and breach of contract; any claim or damage arising out of Executive’s employment with or separation from Vonage (including a claim for retaliation) under any common law theory or any federal, state or local statute or ordinance not expressly referenced above; and any and all claims for counsel fees and costs.

(b)To the fullest extent permitted by law, and subject to the provisions of Paragraphs 4(d) and 4(e) below, Executive represents and affirms that he has not filed or caused to be filed on his behalf any claim for relief against Vonage or any releasee and, to the best of his knowledge and belief, no outstanding claims for relief have been filed or asserted against Vonage or any releasee on his behalf.

(c)In waiving and releasing any and all waivable claims whether or not now known, Executive understands that this means that, if he later discovers facts different from or in addition to those facts currently known by him, or believed by him to be true, the waivers and releases of this Agreement will remain effective in all respects — despite such different or additional facts and his later discovery of such facts, even if he would not have agreed to this Agreement if he had prior knowledge of such facts.

(d)Nothing in this Paragraph, or elsewhere in this Agreement, prevents or prohibits Executive from filing a claim with a government agency, such as the U.S. Equal Employment Opportunity Commission, that is responsible for enforcing a law on behalf of the government. However, Executive understands that, because Executive is waiving and releasing, among other things, any and all claims for monetary damages and any other form of personal relief (per Paragraph 4(a) above), Executive may only seek and receive non-monetary forms of relief through any such claim.

(e)Nothing in this Paragraph, or elsewhere in this Agreement, is intended as, or shall be deemed or operate as, a release by Executive of his rights under the Parties’ Indemnification Agreement,

dated as of April 25, 2013, as amended from time to time (the “Indemnification Agreement”), or any other rights to indemnification relating to his performance of services as an officer of Vonage, including but not limited to those rights to indemnification set forth in Vonage’s Certificate of Incorporation as in effect on the date hereof (the “Certificate of Incorporation”). Notwithstanding the foregoing, the provisions of this Paragraph 4(e) are intended as recitals only and are not intended to provide Executive with any additional contractual rights beyond those contained in the Indemnification Agreement or the Certificate of Incorporation. Furthermore, nothing herein shall affect Executive’s rights to Other Accrued Compensation and Benefits in accordance with the terms of this Agreement or as provided in Section 6 hereof.

5.Consideration and Post-Employment Benefits.

(a)Vonage, for and in consideration of the undertakings of Executive set forth herein and pursuant to Paragraph 4(b)(i) of the Employment Agreement, and intending to be legally bound, and provided that Executive does not revoke this Agreement pursuant to Paragraph 18(d) below, agrees that Vonage will pay or provide the following to Executive, subject to Section 4(d) of the Employment Agreement: (1) severance pay equal to twelve (12) months of the Executive’s Base Salary (as defined in Paragraph 3(a) of the Employment Agreement) and an amount equal to the Executive’s full TBO (as defined in Paragraph 3(c) of the Employment Agreement) for the year of termination, each payable by the Company in installments during its regular payroll cycle over the twelve (12) month period following the Executive’s termination of employment, provided that the first payment shall be made on the sixtieth (60th) day after the Executive’s termination of employment, and such first payment shall include payment of any amounts that would otherwise be due prior thereto, and (2) a pro rata portion of the Executive’s Annual Bonus (as defined in Paragraph 3(c) of the Employment Agreement) for the year of termination, if and to the extent that the Company achieves its performance metrics for such year, payable when bonuses are normally paid to other senior executives of the Company, but in no event later than March 15th of the year following the year to which such bonus relates. All payments are subject to applicable tax withholding. Executive shall be solely responsible for all taxes on the payments under this Agreement.

(b)Notwithstanding anything to the contrary herein, if Executive materially breaches provisions of Vonage’s Employee Confidentiality and Innovations Agreement, dated as of April 25, 2013 (the “Confidentiality Agreement”), Vonage’s Non-Compete Agreement, dated as of April 25, 2013 (the “Non-Compete Agreement”), or Section 7 of the Employment Agreement, Executive shall not be eligible, as of the date of such material breach, for the payments and benefits described in Paragraph 5(a) above, and any and all obligations and agreements of Vonage with respect to such payments shall thereupon cease (and Vonage shall be entitled to recoup any and all such payments and benefits previously paid or awarded to Executive).

(c)In accordance with the provisions of Section 3(b) of the Employment Agreement, the Vonage Holdings Corp. 2006 Incentive Plan, as amended or restated from time to time (the “2006 Incentive Plan”) and the Executive’s individual stock option agreement (the “Stock Option Agreement”), the Parties agree that the equity described in those agreements shall vest and become exercisable in accordance with Section 3(b) of the Employment Agreement (the “Vested Equity”). Other than the Vested Equity, all equity awarded by Vonage to Executive has terminated and is of no further force or effect.

6.Prior Agreements. This Agreement supersedes all prior agreements entered into by Vonage and Executive, except for the following: (1) Section 3(b), Sections 4 through 11 and Section 14 of the Employment Agreement, which terms survive the termination of the Employment Agreement pursuant to Section 17 thereof, (2) the Non-Compete Agreement, (3) the Confidentiality Agreement, (4) the Stock Option Agreements, and (5) the Indemnification Agreement. [List other appropriate agreements between Vonage and Executive.]

7.Resignation from Directorships and Officerships. Pursuant to Paragraph 4(g) of the Employment Agreement, Executive affirms that the termination of Executive’s employment by the

Executive or the Company for any reasons shall constitute the Executive’s resignation from (i) any director, officer or employee position the Executive has with the Company, and (ii) all fiduciary positions (including as a trustee) the Executive holds with respect to any employee benefit plans or trusts established by the Company.

8.Confidentiality of Agreement.

In consideration of Employee’s employment with Vonage or continued employment with Vonage, as the case may be, Employee agrees to be bound by the terms of this Non-Compete Agreement (“Agreement”) as follows:

Restriction on Competition. During the period of Employee’s employment with Vonage and for a period of twelve (12) months thereafter, Employee will not provide services to the portion of any entity that sells and markets residential/home broadband connectivity or broadband voice service (a “Competitive Entity”) as an employee thereof or as a direct individual consultant thereto (or through an entity specifically formed for the purpose of evading the limitations hereof) anywhere within the “Territory,” that term meaning within the United States, Canada, and Brazil, in those States and provinces (or States and provinces contiguous thereto) in which Vonage conducts or is substantially prepared to conduct its business on the date of Employee’s employment termination. Nothing contained in this Section 1 shall be deemed to prohibit Employee from acquiring or holding, solely for investment, publicly traded securities of a Competitive Entity, provided such securities do not, in the aggregate, constitute more than five percent (5%) of any class or series of outstanding securities of such Competitive Entity.

Specific Remedies. If Employee commits a breach of any of the provisions of Section 1, Vonage shall have the right to have such provisions specifically enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such breach will cause irreparable injury to Vonage and that money damages will not provide an adequate remedy.

Independence, Severability and Non-Exclusivity. The right enumerated in Section 2 shall be in addition to and not in lieu of any other rights and remedies available to Vonage at law or in equity. If any of the covenants contained in Section 1 (“Covenants”) or any part of any of them, is found by a court of competent jurisdiction to be invalid or unenforceable, this shall not affect the remainder, or rights or remedies under this Agreement, which shall be given full effect without regard to the invalid portions. The parties intend to and do hereby confer jurisdiction on courts located within the geographical scope of the Covenants. If any of the Covenants is held to be invalid or unenforceable because of the duration or geographical area, the parties agree that the court making such determination shall have the power to reduce the duration and/or area and, in its reduced form, such Covenant shall then be enforceable. No such holding of invalidity or unenforceability in one jurisdiction shall bar or in any way affect Vonage’s right to the relief provided in Section 2 or otherwise in the courts of any other jurisdiction within the geographical scope of the Covenants.

Successors; Binding Agreement. This Agreement and all obligations of Employee hereunder shall inure to the benefit of, and be enforceable by, Vonage and Vonage’s successors in interest.

Entire Agreement. This Agreement constitutes the entire understanding between the parties hereto relating to its subject matter hereof, and supersedes all prior negotiations, discussions, preliminary agreements and agreements relating to that subject matter.

Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New Jersey (without giving effect to conflicts of law provisions).

IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the day and year set forth above.

provide the Termination Services on a 365/24/7 basis in accordance with, and subject to the SLAs set forth and attached to this Addendum as Schedule A hereto. Both Parties shall have dedicated IP interconnects between one another to support the traffic provided under this Agreement. Carrier is required to interconnect with Company at ∗points of public or private interconnection sites via SIP. Carrier acknowledges and agrees that it is required under this Addendum to support the following CODECs g711, g729, and T.38 fax. Carrier acknowledges that a significant majority of Company’s calls, regardless of destination, may be delivered to Carrier using CODEC g711, and Carrier shall at all times remain technically prepared to manage Company’s Termination Services traffic routed via such CODECs.

▪ Routing Through Third Party: “Routing Through Third Party” is a form of routing whereby Carrier offers to terminate traffic through third party carriers (not the “Incumbents”) to all the mobile and fixed telecommunication companies/operators covered by the destinations during the relevant period for which the service is offered.

b) VTS Preferred Service: VTS Preferred Service provides high-quality termination service which endeavors to use but does not guarantee, Direct Routing, Routing Through Incumbent and CLI delivery, in combination with more extensive Routing Through Third Party to most, but not all, dial code ranges within any destination. VTS Preferred receives the second highest priority to Carrier’s supply capacity per destination. ROW traffic will be serviced at the service tier (i.e., VTS Prime or VTS Preferred), as selected from time to time by Company for any given destination.

4. PRICING AND TRAFFIC COMMITMENT: The followingpricing will be effective for the Route Management Term:

d) India Pricing Adjustment (including India Rural): Carrier may modify the India destination(s) Pricing in accordance with the following, ∗:

i. Carrier shall compare the USD-INR exchange rate as reported by Reuters as of 4pm (IST) on the last business day of each Quarter to the “Baseline Exchange Rate”, and in the event the then applicable USD-INR exchange rate has fluctuated by more than ∗ (increase or decrease) from the then current Baseline Exchange Rate: (A) Carrier shall modify the aforementioned India pricing upon providing seven (7) days’ prior written notice (which shall be provided via email to the following address: ratechange@vonage.com), such pricing to become effective at 11:59:59pm (IST) on the seventh (7^th) day following the date of the notice; however, any decreases shall be effective upon receipt of notice (email notification to suffice), and (B) that resulting exchange rate shall become the new Baseline Exchange Rate on a going forward basis until the next time that the Baseline Exchange Rate is adjusted according to the foregoing mechanism. If the then applicable USD-INR exchange rate fluctuates less than ∗ (increase or decrease) from the then current Baseline Exchange Rate, the Baseline Exchange Rate shall remain unchanged; and/or

ii. regulatory changes made by TRAI, Department of Telecom, the Ministry of Finance or any other Indian regulatory agency having jurisdiction over the Termination Services for India destinations (a “Regulatory Change”) which directly result in an increase to Carrier’s direct IDDD traffic termination costs underlying Company’s rates to India destination(s) (excluding any overhead, administrative, capex and internal costs of doing/growing business) of ∗ from Carrier’s analogous costs underlying the prior applicable discounted rate to Company for the affected India destination(s). In such case, such rate increase shall be on a penny-to-penny (or fraction thereof) basis without any mark-up and added incrementally to the discounted rate. Carrier shall endeavor to provide prompt notice of such change upon receipt of such notice from the applicable regulatory agency, and will give Company regular updates as to Carrier’s efforts (if any) to mitigate the impacts of such change. Carrier may not apply any increase under this subsection (ii) without having provided at least seven (7) days prior written notice (email notification to suffice) of such increase, together with sufficient background information, data and detail to enable Company to fully understand the basis for such increase.

iii. If the Carrier’s direct IDDD traffic termination costs underlying Company’s rates to India destination(s) (excluding any overhead, administrative, capex and internal costs of doing/growing business) decreases as a result of a Regulatory Change and the decrease is not reflected in the rate to Company then Company will have the option to re-route its respective India traffic away from Carrier as set forth below. Where Company exercises this option, it will be required to demonstrate to

Portions herein identified by ∗ have been omitted pursuant to a request for confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934, as amended. A complete copy of this document has been filed separately with the Securities and Exchange Commission.

Carrier that it has received a bona fide offer (or offers in the aggregate) from a reputable carrier (or multiple carriers if Company elects to use more than one reputable carrier to satisfy the coverage criteria) capable of providing similar Quality for ∗of India Commitment traffic, at a weighted average cost per minute per destination (“Competitive Rate”) lower than Carrier’s India then-current discounted rate. Notwithstanding anything to the contrary herein, Carrier shall have a right to match the Competitive Rate within ∗Business Days after Company’s presentation of the Competitive Rate, along with a certification as to the carrier(s) term commitment (if any) and associated Quality parameters to Company. If during the notice

period Carrier confirms in writing that it will match the Competitive Rate, Company’s obligations remain unchanged without a right to route away the India traffic. If Carrier does not confirm its agreement to (or ultimately does not) match the Competitive Rate, Company shall have the immediate right to re-route up to ∗of its India Commitment traffic until such time as Carrier reduces its rate to the Competitive Rate, after which Company will route the uncommitted portion of the re-routed India Commitment traffic back to Carrier within ∗business days, and have up to the expiration of each individual commitment with an alternate carrier to which Company is subject, but in no case later than ∗days following the expiration of the ∗ business day period and Carrier’s failure to confirm its agreement to match the Competitive Rate in order to route such re-routed India Commitment traffic back to Carrier. Where such re-routed India Commitment traffic is routed back to Carrier following confirmation of its agreement to match the Competitive Rate, all such India Commitment traffic will be subject to Competitive Rate, and all of the other terms and conditions as existed prior to the time of the re-routing. During the period of time in which Company routes any India Commitment traffic away from Carrier as set forth above, the following Carrier obligations shall not apply: (A) the SLA’s in respect of India Commitment traffic, (B) the base rate and any discounted rate hereunder for India Commitment traffic (i.e., the applicable rate for any such traffic that Company does not route away would be as identified in the then current Carrier Rate Amendment), ∗. For the avoidance of doubt, Company’s remaining obligations under this Addendum with respect to Canada and ROW shall remain unaffected, despite any action (or inaction) to re-route in accordance with the above. and/or

iv. ∗

In the case where Carrier becomes aware of such an event occurring or reasonably likely to occur, Carrier will use commercially reasonable efforts to mitigate against the impact of such factors as long as the condition continues to exist. To the extent immitigable, Carrier shall have the right to modify the India destination(s) pricing upon thirty (30) days’ prior written notice (so long as such circumstances continue to exist at the end of the 30 day notice period) together with sufficient background information, data and detail to enable Company to fully understand the basis for such increase, and such increase shall be limited to reflect the actual penny-to-penny (or fraction thereof) increase without any mark-up in Carrier’s Indian licensed telecommunications access provider’s charges imposed on Carrier for the termination of Company’s India destination IDDD traffic.

If the discounted rate increases for any India destinations (including India Rural destinations), Company will have the option to re-route its respective India traffic away from Carrier as set forth below. Where Company exercises this option, it will be required to demonstrate to Carrier that it has received a bona fide offer (or offers in the aggregate) from a reputable carrier (or multiple carriers if Company elects to use more than one reputable carrier to satisfy the coverage criteria) capable of providing similar Quality for ∗of India Commitment traffic, at a weighted average cost per minute per destination (“Competitive Rate”) lower than Carrier’s increased India discounted rate. Notwithstanding anything to the contrary herein, Carrier shall have a right to match the Competitive Rate within five (5) Business Days after Company’s presentation of the Competitive Rate, along with a certification as to the carrier(s) term commitment (if any) and associated Quality parameters to Carrier. If during the notice period Carrier confirms in writing that it will match the Competitive Rate, Company’s obligations remain unchanged without a right to route away the India traffic. If Carrier does not confirm its agreement to (or ultimately does not) match the Competitive Rate, Company shall have the immediate right to re-route up to ∗of its India Commitment traffic until such time as Carrier reduces its rate to the Competitive Rate, after which Company will route the uncommitted portion of the re-routed India Commitment traffic back to Carrier within three (3) business days, and have up to the expiration of each individual commitment with an alternate carrier to which Company is subject, but in no case later than ∗ following the expiration of the ∗period and Carrier’s failure to confirm its agreement to match the Competitive Rate in order to route such re-routed India Commitment traffic back to Carrier. Where such re-routed India Commitment traffic is routed back to Carrier following confirmation of its agreement to match the Competitive Rate, all such India Commitment traffic will be subject to Competitive Rate, and all of the other terms and conditions as existed prior to the time of the re-routing. During the period of time in which Company routes any India Commitment traffic away from Carrier as set forth above, the following Carrier obligations shall not apply: (A) the SLA’s in respect of India Commitment traffic, (B) the base rate and any discounted rate hereunder for India Commitment traffic (i.e., the applicable rate for any such traffic that Company does not route away would be as identified in the then current Carrier Rate

Notwithstanding Company’s route away rights above, should Company not route away any portion of the India Commitment traffic and the reason(s) for any increase under this subsection (d)(iii) abate or cease in a manner as to reduce Carrier’s costs, or any other development(s) occur to reduce Carrier’s cost, in terminating Company’s IDDD traffic, Carrier is obligated to promptly apply such reductions to Company’s pricing until Company’s pricing is restored to the original discounted rates in Section 4.1(b), as adjusted pursuant to Sections 4.1(d)(i) and/or (ii) above. For the avoidance of doubt, Carrier is not obligated to pass on cost decreases that would reduce pricing below the original discounted rates in Section 4.1(b), as adjusted pursuant to Sections 4.1(d)(i) and/or (ii) above.

For the avoidance of doubt, the Brazilian JV is prohibited from reselling or transferring rates under this Addendum on a wholesale basis.

6. BENCHMARKING:

6.1. Benchmarking Definitions: The following definitions shall be applicable for Benchmarking:

a) “Benchmark Country”means an individual or group of available international dialing code(s) that Carrier assigns for Termination Service, which would include either country code only or country code + city code or country code + mobile range or country code + special service code (excluding Canada and India), as established pursuant to Sections 6.2(a) and updated pursuant to Section 6.5.

e) “Benchmark Performance Rate” means the rate established at the Route Management Effective Date, by calculating as follows:

i. The total weighted average cost of Benchmark Traffic to the Benchmark Destination, calculated using Carrier’s rates to Company at the Route Management Effective Date, divided by

ii. The total weighted average cost of Benchmark Traffic to the Benchmark Destination calculated using the Benchmark Index Rate at the Route Management Effective Date.

f) “Benchmark Period”means the previous, full calendar month prior to a Benchmarking Exercise.

6.2. Benchmarking Principles and Procedures: Benchmarking will be conducted for the VTS Prime and VTS Preferred service categories using an independent third party to be selected by Company at Company’s cost or, if requested by Company by utilizing Carrier’s internal tool at no cost, based on the following principles and procedures:

a) The pricing levied by Carrier will be compared to the rates then-currently loaded into Carrier’s least-cost routing engine and available for use by Carrier to route Termination Service traffic under the VTS Prime and VTS Preferred service tiers, as provided by the ∗global Tier-1 suppliers identified in Schedule B (the “Peer Supplier List”) for a minimum of the twenty (20) Benchmark Countries as provided by Company to Carrier, plus up to ∗additional Benchmark Countries as may be identified by Company in its discretion, based on any countries to which Company previously, currently or is forecasted to deliver IDDD traffic. Company reserves the right to revise the list of Benchmark Countries in its discretion at the time of each Annual Benchmark Exercise.

6.3. Calculation of Benchmark Index Cost and Benchmark Target:

a) The rates used to calculate the Benchmark Index Rates shall be the rates then-currently loaded into Carrier’s least-cost routing engine and available for use by Carrier to route Termination Service traffic under the VTS Prime and VTS Preferred service tiers, as provided by the Peer Supplier List, as applicable to the Benchmark Period.

b) Benchmark Destinations shall be excluded from the Benchmark Exercise where there are less than five (5) Peer Suppliers that provide rates to Carrier.

c) Volumes of traffic provided to Benchmark Destinations during Force Majeure Events shall be excluded from the above calculations.

d) A Benchmark Performance Rate will be established initially upon the Route Management Effective Date in accordance with the Benchmark Exercise described herein.

a) If the result of a Benchmark Exercise is equal to or less than ∗of the then-current established Benchmark Performance Rate, no further action shall be required by either Party.

b) If result of a Benchmark Exercise is greater than ∗of the then-current established aggregate benchmark:

i. The Parties will identify the Benchmark Destination(s) which caused the result to exceed 105%;

ii. Carrier will have ∗ to “cure” the situation, and bring the Benchmark Performance Rate back to or less than ∗of the established Benchmark Performance Rate;

iii. Another Benchmark Exercise will be carried out (at Carrier’s cost) and completed by the ∗following the expiration of the ∗cure period; and

iv. If the results of the new benchmark are still in excess of ∗of the then-current established Benchmark Performance Rate, Company will have the right to re-route the Benchmark Destination(s) identified in subsection (i) above and the ROW Commitment for the upcoming Quarter will be reduced by the amount of traffic sent to such Benchmark Destination(s) until such time as Carrier can demonstrate via a subsequent Benchmark Exercise (at Carrier’s cost) that its cost base has returned to within ∗of the Benchmark Performance Rate established at the Route Management Effective Date, at which time, Company will have fourteen (14) days to reroute the traffic back to Carrier.

6.5 In addition to the Benchmark Exercise above, and occurring on or about each anniversary of the Route Management Effective Date, Carrier shall conduct an additional Benchmark Exercise using Company CDR’s provided by Company as applicable to the Benchmark Period immediately preceding the Benchmark Exercise (the “Annual Benchmark Exercise”). The aggregate benchmark is thereafter revised and re-established to reflect the Benchmark Index Cost as a result of this Annual Benchmark Exercise, based on actual call values and Company’s revised list of Benchmark Countries.

7. BILLING/PAYMENT TERMS: Carrier acknowledges that the current deposit of ∗held by Carrier for Company shall be applied towards the first Invoice under this Addendum. The Company’s credit limit as of the Route Management Effective Date shall be ∗USD. Starting on the Route Management Effective Date and for the Route Management Term, Company shall provide and maintain a prepayment amount (“Prepayment”) to Carrier. The Prepayment will be invoiced at the beginning of every month by Carrier and payable on reception by Company. The Prepayment for each month will be equal to the difference between the previous month’s aggregated Invoice amount and the Company’s Credit Limit. The Parties may mutually agree to use a different method to establish the Prepayment should other estimates be more accurate.

It is understood that (A) the Prepayment will be applied against Invoices set forth below which are applicable to the traffic month the Prepayment is subject to as soon as they are issued on a first in and first out basis, and (B) Company shall continue to pay Invoices as set forth below. After the end of the month, a true-up statement will be issued by Carrier and any adjustments will be applicable on the next payment that becomes due. Carrier shall submit an invoice to Company after the end of the applicable Billing Period (as defined in Section 7.1) which shall include total charges for the applicable Billing Period (“Invoice”). Company shall pay the Invoice amount (less any amounts disputed in good faith pursuant to Section 7.2) to Carrier (1) in US dollars, (2) by wire transfer or such other method as the Parties may mutually agree, and (3) within the applicable Payment Period (as defined in Section 7.1). In no event shall Carrier be liable for the fraudulent or illegal use of the Services by any customers or end-users of Company, or for any amounts that Company is unable to collect from its customers, end users or others.

7.1. Payment Period. 15 day cycle /15 day net payment due via wire for all non-disputed amounts. The billing intervals shall be fifteen (15) days (“Billing Period”) with fifteen (15) days net payment due from date of invoice receipt (“Payment Period”).

7.2. Invoice Disputes. If a portion of an invoice is paid and subsequently disputed by Company subject to the dispute resolution terms of the Agreement, Carrier shall investigate and the parties shall in good faith resolve such dispute within thirty (30) days of notification from Company. If the Parties agree that Company has overpaid for Route Management Services, Carrier shall credit such overpayment against any other amounts owed by Company to Carrier. Any credits shall be made within thirty (30) days by Carrier against Carrier’s invoices. In the event that there are no billable services after Company’s notification against which to issue a credit, Carrier shall issue a cash refund. Unresolved disputes will follow the dispute

resolution process set out in the Agreement. The Parties further acknowledge and agree that no suspension of services or performance obligations shall be permitted pending dispute resolution of disputed amounts, provided undisputed payment obligations are satisfied.

7.3. Back-Billing. Carrier may not invoice services provided to Company more than one hundred twenty (120) calendar days after the end of the month in which Route Management Services were provided or initially raise a claim for payment of a previously issued invoice more than six (6) months after the invoice date (either, a “Late Claim”). Company is not obligated to pay Late Claims and Carrier waives all rights and remedies related to Late Claims, but excluding any tax obligations for services provided. Carrier will use good faith efforts to issue separate invoice for any and all arrears billing with proper dates and time periods of incurred usage expense.

7.4. Billing Increments. Termination Services shall be billed in one (1) second increments with a one (1) second minimum, except for Mexico which shall be billed in sixty (60) second increments with a sixty (60) second minimum. Any process for the rounding of charges shall be equally applied by the Parties.

Applicable Time Zone: __ EST X_ GMT __ Other (Please specify): _________ (Spain and UK indicate local switch time)

8. CREDIT LIMIT AND DEPOSIT: Carrier may increase the Credit Limit at any time upon notice to Company.  If the financial condition or payment history of the Company (or any surviving entity as a result of a Change of Control event) materially deteriorates after the Effective Date, as evidenced by a material downgrade in its credit rating or debt securities, a bond or loan covenant default, a history of repeated, consecutive, uncured, delinquent payments (not otherwise disputed herein) or other similarly material and demonstrable criteria that makes such condition or payment history unacceptable to the Carrier in its reasonable business judgment, the Carrier may decrease the Credit Limit, or require commercially reasonable alternate arrangements (e.g. LOCs, deposits or prepayments), solely to the extent necessary to mitigate its legitimate credit risk and exposure upon no less than ∗prior written notice to Company.  If at any time Carrier determines that the sum (the Accrued Liability) of (i) total invoiced amounts which remain unpaid and undisputed, plus (ii) the unbilled but accrued usage of Company, has exceeded the then current Credit Limit, Carrier shall have the right to demand by written notice that Company make an immediate payment to Carrier by telegraphic transfer (or such other method as agreed by the parties) of such amount required to reduce its aggregate Accrued Liability to less than the Credit Limit. Upon written notice to Company, the demanded amount shall become immediately due and payable and Company shall pay such amount within three (3) business days of Company’s receipt of such notice. If Company fails to remit such payment when due, Carrier shall have the right without further notice to temporarily suspend the Route Management Services until such amounts are received by Carrier.

9. ROUTE MANAGEMENT TERM: Notwithstanding anything contained in the Agreement to the contrary,the Route Management Service and the obligations under this Addendum shall commence on Route Management Effective Date and shall remain in force for an initial five (5) year term (the “Route Management Term”). Notwithstanding the foregoing, each Party shall have the right to terminate this Addendum by providing six (6) months’ notice prior to the commencement of Year 4 of the Route Management Term. Upon such notification of termination, the Parties shall immediately enter into good faith negotiations with the goal of reaching an agreement within thirty (30) days of receipt of such termination notice. For the avoidance of doubt, the termination for convenience rights under Section 3.2 of the Agreement shall not apply to this Addendum.

10. ASSIGNMENT AND CHANGE OF CONTROL: The Agreement (including this Addendum) may not be assigned without the express written consent of the other Party, which consent shall not be unreasonably withheld; provided however, that a Change of Control of a Party, or any deemed assignment (whether or not by operation of law) of the Agreement (including this Addendum) resulting from a “Change of Control” of a Party, shall not require the consent of, or compliance with any precondition of the other Party. In addition, either Party may assign this Agreement to an Affiliate of such Party without the need for consent, but with at least ten (10) days prior written notice of such assignment. For purposes of this Agreement, “Change of Control”means (i) a merger involving a Party in which such Party is not the surviving entity; (ii) a merger involving a Party in which the Party is the surviving entity but in which securities possessing greater than fifty percent (50%) of the total combined voting power of a Party’s outstanding voting securities are transferred to other Persons; (iii) a sale or disposition of all or substantially all of a Party’s property, assets or business or merger into or consolidation with any other Person (other than to a Party’s Affiliate); or (iv) a sale, assignment or other transfer of a Party’s securities possessing greater than 50% of the total combined voting power of such Party’s outstanding voting securities at the time of such transfer. Any attempted or purported assignment not permitted hereunder shall be void.

11. LOCAL LOOP CHARGES: Company shall be responsible forall local loop charges that Carrier is required to pay to any third party service provider that are incurred on behalf of Company and the local loop charges shall survive reduction, suspension and/or termination of services.

12. FORECAST ESTIMATES: At least fifteen (15) days prior to the start of each Quarter,Company shall provide to Carrier a written non-binding forecast estimate of traffic volumes for that Quarter, including without limitation, endeavoring to identify any anticipated traffic volume spike periods (the “Forecast Estimate”). If Carrier receives a Forecast Estimate for any destination(s) which are materially greater than prior Forecast Estimates and the capacity for which is reasonably unplanned for such material increase (“Over-Flow Traffic”), then Carrier shall notify Company promptly (within five (5) Business Days) if it cannot adequately provide the necessary capacity to satisfy the Over-Flow Traffic and confirm the maximum capacity it has for such destination(s) traffic. Company has the option to route away the portion of the Over-Flow Traffic exceeding Carrier’s capacity. Company acknowledges that if it does not route away such Over-Flow Traffic, Carrier is relieved from any liability associated with not performing to the minimum SLAs with respect to such destination traffic. For the avoidance of doubt, Company’s ROW commitment will not be reduced due to Carrier’s inability to provide termination for volumes in excess of ∗of previous volumes sent by Company to Carrier to any particular destination.

13. TERMINATION: For avoidance of doubt, there is no right of termination for convenience by either party (except for the termination right in Section 9 of this Addendum) notwithstanding any termination for convenience rights under Section 3.2 of the Agreement, nor by Carrier for a material change in financial condition of Company that poses a material financial risk to Carrier notwithstanding the termination rights set forth under Section 3.3(c) of the Agreement; but this Addendum is subject to all other termination rights, including for cause, as set forth in this Addendum and the Agreement; provided that any termination under Section 3.3(a)(ii) of the Agreement must be based on an uncured breach of a material obligation under this Addendum. Company may terminate this Addendum in whole or in part due to Carrier’s SLA failures as set forth in Schedule A. Any expiration or termination of the Addendum is not considered a termination or expiration of the Agreement.Should Carrier terminate this Addendum in accordance with Suspension/Reduction/Termination provisions of the Agreement (except for Section 3.2 or Section 3.3(c) of the Agreement which are not available under this Addendum), or should Company terminate this Addendum for any reason (except for Section 3.2 or Section 3.3(c) of the Agreement which are not available under this Addendum) other than a material breach solely attributable to Carrier which breach has not been cured within thirty (30) days, then Company shall be fully liable to pay to Carrier any termination charges that Carrier is required to pay to any Third Party telecommunications service provider, if any, for terminating their facilities that were incurred on behalf of Company.

IF A DEPOSIT IS THEN WITHHELD BY CARRIER: With respect to this Addendum only, notwithstanding Section 3.3 of the Agreement, neither the Agreement nor this Addendum may be terminated by Carrier due to non-payment unless such charges are undisputed and are, in the aggregate, in excess of the Company’s unapplied unused deposit held by Carrier (if a deposit is then held by Carrier), and remain unpaid for at least five (5) business days after receipt of written notice (which notice must be delivered in accordance with the notice provisions and refer to the right to terminate if payment is not timely met within the five (5) business day period.) Any termination of this Addendum or the Agreement due to Section 3.3(b), (d) or (e) of the Agreement will have the effect of terminating the Parties’ remaining executory obligations under this Addendum, including the remainder of any unmet minimum commitments and pricing commitments, without affecting payment obligations of invoices for services rendered, or any other rights and remedies under the Agreement (independent of the Addendum) regarding the specific basis for the termination.

14. OFFICER CERTIFICATION: Each Party, upon written request of the other Party and no more often than twice per year, will provide to the other Party within thirty (30) days thereafter a senior corporate officer’s (designated as a corporate officer by such Party’s by-laws) certificate confirming its compliance with the terms of this Addendum in all material respects.

15. AUDIT RIGHTS: Each Party shall have an annual audit right to the extent reasonably necessary to permit a Party or an auditor appointed by a Party to:

a)For Company: Verify Carrier’s compliance with the terms of this Addendum.

b)For Carrier: Verify Company’s compliance with the terms of this Addendum.

All such audits shall be conducted: (i) no more than once per year during the Route Management Term; (ii) with no less than sixty (60) days prior written notice; (iii) at the cost of the auditing Party; (iv) provided any appointed auditor does not have material conflict of interest with the audited Party; (v) subject to the auditor complying with the audited Party’s reasonable confidentiality and security requirements; and (vi) provided that: (A) it shall be solely for the purposes of verification of compliance with the terms

2.1 Measurement Period

2.1.1 During the Route Management Term, Carrier shall use industry standard measurement tools to accurately measure, monitor and report the Service Levels, as more specifically set out in Paragraph 3 of this Schedule.

2.1.2 Carrier shall endeavor to meet or exceed the Service Levels, as set forth in this Schedule.

3.    SERVICE METRICS FOR CARRIER TERMINATION SERVICES

This section sets out the metrics which shall be used as the basis for setting Service Levels.

3.1 Metrics relating to Carrier Termination Services: Termination Services in relation to specific Service Levels and destinations will be managed and performance reported against the following metrics listed below (‘Performance Services Metric’). The definitions of the Performance Service Metric are set out at Annex A to this Schedule and the manner in which Performance Service Levels are set against the Performance Service Metric in relation to specific Service Levels and destinations is set out in the table to be agreed between the Parties in the form set out at Annex B to this Schedule (‘Destination Service Levels Table’). Subject to the applicable Service Levels and destinations, the Performance Services Metric may include:

• ∗

The Parties will use reasonable endeavors over the Route Management Term to work towards improving the tools for enhancing Service Level performance.

3.2 Peak Periods: The Parties acknowledge that the aforementioned Performance Services Metric may be impacted periodically by in-country market circumstances such as government-recognized national holidays (“National Holidays”). National Holiday - related impacts shall be considered as Force Majeure Events and such instances shall not be held contributory to the above measurements.

3.2.1    Notwithstanding the foregoing,Carrier and Company shall work together in good faith to develop a capacity plan (“Capacity Plan”) no less than thirty (30) days prior to National Holidays in major destinations to ensure sufficient capacity is available to accommodate for peak traffic during such events. In the event the Parties agree on a Capacity Plan, the applicable Performance Service Metric shall still apply during that National Holiday. In the event the Parties do not agree on a Capacity Plan, and the traffic during the National Holiday cannot be accommodated by Carrier, Company may route away the affected traffic (in which case, the applicable India Commitment and Canada Commitment, respectively, would not apply).

3.3 Fault Handling Metrics: Carrier will provide Company with access to a fully trained fault management team. The specific Fault Handling Service Level definitions are defined below and the specific Service Category to which each metric applies is set out at the Destination Service Levels Table.

3.4 Response Time: The time between Company informing Carrier’s designated contact either by means of telephone, e-mail or via Carrier’s customer portal that in Company’s opinion a Fault (as defined in Section 3.6 below) has occurred and the confirmation from Carrier that the Fault is acknowledged.

3.5 Resolution Time: The time between Company informing Carrier’s designated contact either by means of telephone, e-mail or via Carrier’s customer portal that in Company’ opinion a Fault has occurred and the time at which Company receives by e-mail or via the Carrier customer portal notification that the Fault has been resolved. If Company identifies that the Fault still persists after the closing of a trouble ticket, the Fault shall be considered not closed and the resolution time shall restart from that point of notification from Company. Subject to the Fault Reporting Procedures as set forth in Annex D,Carrier will inform Company by e-mail, telephone or via the Carrier customer portal of the status in resolving any Fault upon request by Company.

3.5.1 Testing Period: From the time Carrier notifies Company that the validated issue is resolved, Company agrees to test and provide ticket fault resolution or feedback within twenty-four (24) hours. If ticket is closed then Company will re-route traffic as promptly as possible under the circumstances. If Company perceives the issue still exists, Company will provide proof (e.g. call samples, data to support, etc.) of the existence of the issue.

3.5.2 Carrier will endeavor to proactively notify Company of network issues it becomes aware of.

3.6 Fault Definitions: When reporting Faults to Carrier, Company will employ standard definitions of the severity of the Fault. Priority definitions are defined below. Company reserves the right to contact Carrier and increase the Priority based on the impact to its customers. The Fault Handling Metrics for the newly-assigned Priority will commence upon such notice.

a) Priority 1 Faults: Priority 1 Faults are a “Material Service Failure” which means any one or more of the following (provided that at all times a Fault in respect of a single telephone number shall not constitute a Material Service Failure):

(i) Total outage of Carrier’s Termination Services network ∗NER;

(ii) Complete loss of Voice Termination Service access to any destination listed on the Carrier Rate Amendment;

(iii) Severe destination impairment on the Termination Service  to any destination on the Carrier Rate Amendment for that service, to include:

• For traffic routed on Prime Service Level: Performance Service Metrics falling below key performance targets as set out in the Destination Services Levels Table: ∗of target for a rolling 7 day period;

• Multiple Faults to the same destination on the Termination Service listed in Carrier Rate Amendment twice within 24 hours; or

• Company opens ticket which is voice impairment related, is customer impacting (Company to provide a screen shot from internal dashboard to show data on customer impact), Company routes specific destination traffic away, and issue is validated to be a Carrier issue.

b) Priority 2 Faults: Means any instance when the following measures in respect of any Termination Service destination fails to be met, either:

i) For traffic routed on Prime Service Level: Performance Service Metrics falling below key performance targets as set out in the Destination Services Levels Table: ∗of target for a rolling 7 day period; or

ii) For traffic routed on Preferred Service Level: Performance Service Metrics falling below key performance targets as set out in the Destination Services Levels Table: ∗of target for a rolling 7 day period.

i) For traffic routed on Prime Service Level: Performance Service Metrics falling below key performance targets as set out in the Destination Services Levels Table: ∗of target for a rolling 7 day period;

ii) For traffic routed on Preferred Service Level: Performance Service Metrics falling below key performance targets as set out in the Destination Services Levels Table: ∗of target for a rolling 7 day period;

iii) Any other Fault not otherwise specified in this Section 3.6(c) to this Schedule A; or

iv) Company opens ticket which is voice impairment related, may or may not be customer impacting, Company does not route away traffic and issue is validated to be a Carrier issue

4.SERVICE LEVEL EXCLUSIONS: Notwithstanding anything stated to the contrary herein, Carrier shall be relieved from any failure to achieve a Performance Service Metric to the extent that the cause of an Incident and / or fault is determined to have occurred as a result of one or more of the following conditions:

(a) Any Faults not reported by Company to Carrier as Qualified Trouble Tickets;

(b) Force Majeure Events: Neither Carrier nor Company shall be held responsible for any unforeseen Faults as arising from Force Majeure Events as defined in the Addendum. Carrier is responsible for informing Company immediately of all such issues and events and using all commercially reasonable efforts to provide an alternative solution.  In such an event, if the Company is required to route away traffic, Company will be relieved of its Traffic Volume Commitment for the affected period by an amount equal to the daily average amount of traffic to affected destination over the seven (7) days prior to when the Force Majeure Events first occurred multiplied by the number of days Company was required to route away and Company may route such traffic to Third Party telecommunications suppliers at its discretion; provided, however, that Carrier will notify Company of route availability upon elimination of the Force Majeure Event at which time Company will begin a testing period of seven (7) days. Once testing is complete to Company’s reasonable satisfaction, Company will route traffic back to Carrier within the following seven (7) day period. If the Company continues to route traffic to Carrier during the Force Majeure Event, the amount of traffic Company sent to Carrier for termination will be deducted from the amount of traffic for which it requested relief;

(c) Scheduled Work Outages. If Company is properly notified in accordance with Annex E – Company CRQ Process (via email to Company’s designated NOC contact to suffice) of a “planned outage”, the parties agree that any Trouble Tickets that results from such a planned outage shall not be considered as a Faults, to the extent that such planned outages are limited to three (3) occurrences per Quarter and are in each case completed within an agreed-upon maintenance window.  In any event, Company will be relieved of the Traffic Volume Commitment for the entire duration of each planned outage (e.g., whether or not properly notified) by an amount equal to the daily average amount of traffic to affected destination over the seven (7) days prior to when the planned outage first occurred, multiplied by the number of days (and fractions thereof) of the planned outage;

(d) For traffic sent by Company to Carrier during Peak Periods to the extent excluded under Section 3.2 of this Schedule;

(e) Degradation of performance on the affected destination for the period in question is found to be the result of originating customer behavior which affects the successful delivery of the call;

(f) In the event actual ROW traffic sent by Company to Carrier is in excess of the Company's non-binding forecast by more than ∗to a particular destination, Carrier shall be relieved of the SLA with respect to the excess traffic to the extent that such failure arises from the excess traffic;

ANNEX A

Definitions of Service Metrics

Network Efficiency Ratio

Network Effectiveness Ratio is described in ITU E.411. NER is designed to express the ability of networks to deliver calls to the far-end terminal for Termination Services. NER expresses the relationship between the number of seizures and the sum of the number of seizures resulting in either an answer signal, or a user busy, or a ring no answer, or, in the case of ISDN, a terminal rejection/unavailability.

Seizure

A call that is accepted for delivery by the receiving network from the originating network for Termination Services. Once seized, a call is now the responsibility of the receiving network to complete.

Answer to Seizure Ratio (ASR)

ASR: As described in ITU E.411-E437, Answer Seizure Ratio (ASR) gives the relationship between the number of seizures that result in an answer signal and the total number of seizures for Termination Services. This is a direct measure of the effectiveness of the service being offered onward from the point of measurement and is expressed as a percentage as follows:

ASR = (Seizures resulting in answer signal/Total seizures) X 100    

Answer Bid Ratio (ABR)

ABR: As described in ITU E.425, Answer Bids Ratio gives the relationship between the number of bids that result in an answer signal and the total number of bids for Termination Services. This is a direct measure of the effectiveness of the service being offered and is expressed as a percentage.

ABR - (Bids resulting in answer signal/Total Bids) X 100

Bid

Bid: As described in ITU E.410 Annex 10, a bid is an attempt to obtain a circuit in a circuit group or to a destination. A bid may be successful or unsuccessful in seizing a circuit in that circuit group or to that destination.

Average Length Of Conversation (ALOC)

ALOC: As described in ITU E.437, ALOC is the Average Length Of Conversation for completed calls using the Termination Services. A statistically significant difference in ALOC between two routes may be considered as an indication of some irregularity warranting further investigation.

Number of Repeat Faults

Number of repeat faults is used to describe the number of incidents reported by Company to Carrier as Faults that following Carrier communication of the incident being cleared and Company’s acceptance of the Fault being cleared are subsequently reported again as Faults of the same nature within a period of ∗hours of the initial or subsequent clear message from Carrier to Company.

Number of Priority 1 incidents per month

The number of Priority 1 incidents per month is used to describe the number of Priority 1 Faults that Company reports to Carrier and that Carrier subsequently communicates a clear cause other than “Fault not found”.

Valid Call Attempts

Is used to describe a call request from a Company network to a Carrier network including a valid called party number. Attempts where the called party number is wrong or not in the correct format are excluded form the number of Valid Call Attempts.

Mean Time To Repair

The Mean Time To Repair is used to describe average time between Company opening Qualified Trouble Tickets by the mechanisms specified through the Fault Reporting Process as set forth in Annex C of this Schedule and Carrier communicating the clearance of those Tickets. In any case that a fault is subsequently found not to be cleared the Mean Time To Repair will be from the start of the original fault to the eventual close of the same fault.

Qualified Trouble Tickets

Qualified Trouble Tickets is used to describe those tickets that are opened as per the Fault Reporting Process as set forth in Annex D to this Schedule and which relate to Faults meeting the definitions of Fault Definitions as set forth in Section 3 of this Schedule.

ANNEX B

SERVICE LEVELS

The following targets will apply to any destination where for each Service tier Company makes no fewer than 300 Valid Call Attempts on a daily average basis to the applicable Destination. If a Peak Period occurs during the month, then for the destination or metric excluded for that period, the number of Valid Call Attempts on a daily average will be reduced pro rata by the duration of the Peak Period in days as a proportion of the total days in the month.

Annex C:

SLA Failure Remedies

For clarification purposes, the following shall apply to Priority 1 and 2 Faults that are initiated by Company upon its detection of an issue, but excluding any Trouble Tickets that arise due to any Service Level Exclusions (as defined in Section 4 above)):

Chronic Events
	Priority 1 Faults	Priority 2 Faults
Chronic Issue	∗ Priority 1 Faults to the same destination for any rolling ∗day period. OR For India destinations (excluding India Rural) and Canada destinations (excluding the Canada High Cost Codes), only: Greater than ∗Faults in a ∗day period where Carrier did NOT meet the MTTR requirement in Annex B.	*Priority 2 Faults to the same destination during any rolling ∗day period.
Chronic Condition	∗Chronic Issues during any rolling ∗day period to the same destination or ∗complete failure across Carrier’s Termination Services network. OR  For India destinations (excluding India Rural) and Canada destinations (excluding the Canada High Cost Codes), only: Greater than ∗Faults in a ∗day period where Carrier did NOT meet the MTTR requirement in Annex B.	*Chronic Issues during any rolling ∗day period to the same destinations.

Portions herein identified by ∗ have been omitted pursuant to a request for confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934, as amended. A complete copy of this document has been filed separately with the Securities and Exchange Commission.

Should Company experience Chronic Events (defined as per table above), it may have the right to route away Termination Services traffic for the affected destination (at the DNIS level). Accordingly, in the event of a Chronic Event, Company may elect to be relieved of its Traffic Volume Commitment for the affected destination (at the DNIS level) without penalty during the Event. In the event Company is unable to fulfill the Traffic Volume Commitments as the result of any one or more Chronic Event(s), Company shall be relieved of any shortfall penalty or other remedy associated with the affected traffic to the affected destination(s) (at the DNIS level), and Company may route such traffic to Third Party telecommunications suppliers at its discretion as a direct result of such Chronic Event(s).

a. Relief from the Traffic Volume Commitment will be equal to the daily average amount of traffic over the ∗days prior to when the first Chronic Event occurred, multiplied by the number of days of the Event. Company shall be relieved from its Traffic Volume Commitment obligations for the affected destination (at the DNIS level) from the time when the Event first occurred. Should Company elect any relief from its Traffic Volume Commitment to an affected destination (at the DNIS level), Carrier shall not be relieved of its pricing, capacity or SLA obligations. Upon notice from Carrier, Company will begin a testing period of ∗days. Once testing is complete to Company’s reasonable satisfaction, Company will route traffic back to Carrier within the following ∗day period.

b. Solely with respect to India destinations, in the event Chronic Condition(s) occur ∗or more times in any rolling ∗month period during the Route Management Services Term, Company shall have a right to terminate the Addendum in whole or in part upon no less thirty (30) days written notice to Carrier, provided such notice is sent within ∗days of the completion of the second such Chronic Condition(s) giving rise to this termination right.

c. Solely with respect to Canada, in the event of ∗Chronic Condition(s), Company will be relieved of its Canadian Commitment to Carrier. In such instance, the affected destination will no longer be subject to SLA’s under this Schedule.

d. In addition to and without limiting Company’s rights and remedies under the foregoing, in the event of ∗Chronic Condition(s) affecting a ROW destination (at the DNIS level), the ROW Commitment will be reduced by the daily average amount of traffic over the ∗days prior to when the first Chronic Condition occurred for the remaining term of the Addendum and route such traffic to Third Party telecommunications suppliers at its discretion. In such instances, the affected destination will no longer be subject to SLA’s under this Schedule.

e. For the ∗Commitment only, if a Company shortfall of Traffic Volume Commitment minutes can be traced back to a Carrier caused by Priority 1 Faults where minute relief was not granted, then Company will not be in violation of any shortfall obligations.

Mar 2013

the service outage or service deficiency may be related to a particular link with a foreign carrier or localised within the territory of a foreign administration. In that case, the GNMC will coordinate the testing and repair work with the foreign carrier or administration. Throughout this process the TSC-W will follow the progress of this work, keeping

the customer advised of the fault resolution process and ensuring rapid fault resolution.

Either upon receipt of a called-in fault report or from automatic fault detection, network operations personnel investigate to determine the source of the fault and attempt to resolve it. If this is not feasible, maintenance personnel are dispatched on a worldwide basis

to the source of the problem.

2. Repair Time and Escalation

Tata Communications maintains aggressive goals for Mean Time To Repair (MTTR).

If the MTTR threshold is in jeopardy and/or if the customer feels it is necessary, the customer may begin escalating the trouble within Tata Communications.

The following escalation guidelines apply to customer service interruptions:

- Escalation should be made at the given intervals until the trouble is isolated and a repair plan is implemented.

- Escalation can vary after the isolation of the fault depending on repair activity underway and is not necessarily limited to set intervals.

- Escalation will be based on fault duration, not length of time at the fix agency (even if the fix agency just received the ticket). The escalation clock starts when the ticket is opened.

Each Party agrees to comply with all applicable anti-bribery laws and further agrees that any failure by a Party to comply with the provisions of this clause shall constitute a material and incurable breach of this Agreement.

6.LIMITATIONS OF LIABILITY.

6.1    The Parties acknowledge that they have no control over how a foreign administration or third party carrier establishes its own rules and conditions pertaining to international telecommunications services. Other than with respect to any service level agreements set forth in an applicable service schedule(s) (including its exhibits and addenda), the Parties agree that they shall not be liable to each other for any loss or damage sustained by the other Party, its interconnecting carriers, its customers or end users due to any failure in or breakdown of the communication facilities associated with providing the Services.

6.2    NEITHER PARTY SHALL HAVE ANY LIABILITY WHATSOEVER FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, OR SPECIAL DAMAGES SUFFERED BY THE OTHER OR BY ANY ASSIGNEE OR OTHER TRANSFEREE OF THE OTHER, EVEN IF INFORMED IN ADVANCE OF THE POSSIBILITY OF SUCH DAMAGES.

6.3    Each Party’s total liability to the other under this Agreement for any and all claims, demands, causes of action, liabilities, expenses, damages, losses, or liabilities (including reasonable attorneys’ fees) (collectively, “Claims”) by a Party shall not exceed in the aggregate an amount equal to twelve (12) times the aggregate amount invoiced by Carrier for Services rendered prior to the month in which the event giving rise to liability occurred. For avoidance of doubt, a “Claim” involves any Claim or series of Claims arising from the same occurrence, omission or common nucleus of facts.

6.4    Notwithstanding the foregoing, the limitations set forth in Sections 6.2 and 6.3 shall not apply with respect to:

a.    amounts correctly invoiced for Services properly rendered under this Agreement; and

b.    damages arising out of or related to Carrier’s breach of its most-favored nation and/or other pricing protections set forth under an applicable service schedule(s) (including its exhibits and addenda).

Each Party shall have a duty to mitigate damages for which the other Party is responsible.

7.INDEMNIFICATION.

7.1    Contract Breach and Product Liability. Each Party agrees to indemnify, defend and hold the other Party (including its affiliates, officers, directors, employees, contractors and representatives) harmless for third party Claims: (i) arising from the indemnifying Party’s material breach of any obligation, representation or warranty under this Agreement; (ii) any material violation by the indemnifying Party or its affiliates of any applicable laws in connection with the performance of its obligations under this Agreement; or (iii) relating to any physical damage to property, or personal injury or death, caused by the indemnifying Party or any of its affiliates, agents or subcontractors.

7.2    Intellectual Property.

a.    Carrier also agrees to indemnify, defend, protect and hold harmless Vonage (including its affiliates, officers, directors, employees, contractors and representatives) from and against, any and all third party claims, injuries, losses, damages, liabilities or expenses of any kind, including reasonable attorneys’ fees and costs of litigation, which third party claims arise out of or result from, directly or indirectly, in whole or in part from any third-party claim of infringement of any U.S. patent, copyright, trademark, service mark, trade secret or other intellectual property rights of a third party arising from or related to the Services.     

b.    If any Service becomes, or is likely to become, the subject of a Claim of infringement of intellectual property, Carrier shall, in addition to indemnifying Vonage as provided in Section 7.2(a), promptly at Carrier’s expense use best efforts to: (i) secure the right to continue using the Service; or (ii) replace or modify the Service to make it non-infringing, provided that any such replacement or modification shall not degrade the performance or quality of the affected component of the Services. In the event neither of such actions can be accomplished by Carrier, and only in such event, Vonage may at its option terminate this Agreement without liability upon notice to Carrier and shall be equitably compensated for Services paid for and not received.

7.3    Indemnification Procedure.

8.CONFIDENTIALITY.

8.1    Obligations. Each Party acknowledges that Confidential Information may be disclosed to the other Party during the course of this Agreement. Each Party agrees that during the Term and for a period of three (3) years thereafter, it shall use at least the same degree of care as it employs to avoid unauthorized disclosure of its own information, but in no event less than a commercially reasonable degree of care, to prevent the duplication or disclosure of Confidential Information of the other Party, other than by or to (i) its employees or agents who must have access to such Confidential Information to perform such Party’s obligations hereunder, who shall each agree to comply with confidentiality requirements no less restrictive than those contained in this Article; and (ii) independent third-party auditors that agree in writing to comply with confidentiality requirements no less restrictive than those contained in this Article. Notwithstanding the foregoing, either Party may issue a disclosure containing Confidential Information without the consent of the other Party, to the extent such disclosure is required by law, rule, regulation or government or court order. In such event, the disclosing Party shall provide at least seven (7) days prior notice of such proposed disclosure to the other Party. Further, in the event such disclosure is required of either Party under the laws, rules or regulations of any applicable governing body, such Party shall: (a) redact mutually agreed-upon portions of this Agreement to the fullest extent permitted under applicable laws, rules and regulations; and (b) submit a request to such governing body that such portions and other provisions of this Agreement receive confidential treatment or otherwise be

held in the strictest confidence to the fullest extent permitted under the laws, rules or regulations of the applicable governing body.

8.2    Definition. For purposes hereof, "Confidential Information" means any information, in any form, furnished or made available directly or indirectly by one Party (the "Disclosing Party") to the other (the "Receiving Party") relating to or disclosed in the course of the negotiation or performance of this Agreement, that is, or should be reasonably understood to be, confidential or proprietary to the Disclosing Party (including the terms of this Agreement; information transmitted by means of the services; Vonage usage statistics; all usage data and reports collected by Carrier and all reports provided to Vonage by Carrier; calling patterns; invoices and any supporting information provided by Carrier or Vonage with respect to such invoices; information audited pursuant to the Agreement; Vonage's Customer Information (defined below); automatic numbering identification (“ANI”) data and information; the relations of the Disclosing Party with its customers; employees and service providers; technical processes and formulas; source codes, product designs, sales, cost and other unpublished financial information; and product and business plans projections and marketing data); provided, however, that "Confidential Information" shall not include information: (i) already lawfully known to or independently developed by the receiving Party without violation of any confidentiality obligation; (ii) lawfully disclosed in published materials without violation of any confidentiality obligation; (iii) generally known to the public; or (iv) lawfully obtained from any third party without violation of any confidentiality obligation. Vonage may disclose this Agreement under a comparable non-disclosure agreement in response to a third party due diligence request supporting a financing or non-ordinary course of business corporate transaction so long as such disclosure is not to a direct competitor of Carrier, and such requestor is subject to a comparable non-disclosure agreement.

8.2    Collection, Use and Disclosure of Vonage Customer Information. Carrier shall ensure that its collection, use and disclosure of information regarding Vonage’s customers or subscribers names, email addresses, addresses, telephone numbers and other identifying or personal information provided by Vonage or otherwise obtained in connection with performance of their obligations hereunder (collectively, “Customer Information”) complies with: (i) all applicable laws and regulations; and (ii) Vonage’s standard privacy policies, provided that Carrier shall not collect, process, store, use or disclose any Customer Information except for the sole and exclusive purpose of fulfilling its obligations hereunder. All Customer Information constitutes Confidential Information for purposes of this Agreement. Without limiting the foregoing, Carrier shall not disclose Customer Information collected hereunder to any third party in a manner that identifies an individual Vonage customer or subscriber (or aggregate Vonage customers or subscribers as a discrete group) as a user of the Services provided hereunder or a Vonage product or service, or use Customer Information to market any another produce or service.

9.RESOLUTION OF DISPUTES.

9.1    Prior to the initiation of litigation or mediation, the Parties shall first use all commercially reasonable efforts to resolve their dispute informally. In particular, upon the written request of a Party referencing this Section 9, each Party shall appoint a designated senior representative who does not devote substantially all of his or her time to performance under this Agreement, whose task it will be to meet for the purpose of endeavoring to resolve such dispute. The representatives shall discuss the problem and attempt to resolve the dispute without the necessity of any formal proceeding. The specific format for the discussions shall be left to the discretion of the designated representatives. Notwithstanding the foregoing, this Section 9.1 shall not prevent a Party from instituting, and a Party is authorized to institute, litigation earlier to avoid the expiration of any applicable limitations period, or to preserve a superior

position with respect to other creditors, or from seeking any injunctive relief to which the Party may be otherwise entitled

9.2    Litigation regarding such dispute (other than billing disputes, which shall be exclusively handled pursuant to the procedures set forth in Section 9.3) may not be commenced until the earlier of: (i) the designated representatives concluding in good faith that amicable resolution through continued negotiation of the matter does not appear likely; and (ii) thirty (30) days after the initial written request to appoint a designated representative pursuant to Section 9.1 (this period shall be deemed to run notwithstanding any claim that the process described in this Section was not followed or completed);.

9.3    In the event a billing dispute shall arise between the Parties to this Agreement which cannot be amicably resolved within thirty (30) days after the initial request to appoint a designated representative pursuant to Section 9.1, the Parties agree to participate in no less than four (4) hours of mediation in order to resolve the matter. The mediation will involve each side of the dispute sitting down with a mutually-agreed upon impartial mediator, who shall be an attorney or retired judge practicing in the area of telecommunications law, to attempt to reach a voluntary settlement. The mediation will be conducted in New York, NY and will involve no formal court procedures or rules of evidence.

9.4    Each Party agrees to continue the performance of its respective duties and obligations under the Agreement during the pendency of any dispute.

10.GOVERNING LAW. Each Party agrees to continue performing its obligations under this Agreement during any dispute. The Agreement shall be interpreted, construed and enforced in all respects in accordance with the laws of the State of New York, except for its conflicts of laws principles. Each Party irrevocably consents to the exclusive jurisdiction of the courts of the State of New York and the federal courts situated in the State of New York in connection with any action to enforce the provisions of this Agreement, to recover damages or other relief for breach or default under this Agreement or otherwise arising under or by reason of this Agreement. Notwithstanding the foregoing, any judgments entered in an action under this Agreement may be enforced in any court of competent jurisdiction.

11.FORCE MAJEURE.

11.1    Neither Party shall be liable for any default or delay in the performance of its obligations under this Agreement if and to the extent such default or delay is caused, directly or indirectly, by fire, flood, lightning, earthquake, elements of nature or acts of God, riots, civil disorders, rebellions or revolutions, or any other cause beyond the reasonable control of such Party; provided, however, that the non-performing Party is without fault in causing such default or delay, and such default or delay could not have been prevented by reasonable precautions and cannot reasonably be circumvented by the nonperforming Party through the use of alternate sources, workaround plans or other means (any such event a “Force Majeure Event”). Notwithstanding the foregoing, the failure of a Carrier supplier to perform under its arrangement with Carrier shall not constitute a Force Majeure Event for Carrier.

9.2    For any Force Majeure Event, the non-performing Party shall be excused from further performance or observance of the obligation(s) so affected for as long as such circumstances prevail and such Party continues to use its best efforts to recommence performance or observance whenever and to whatever extent possible without delay. Any Party so delayed in its performance shall immediately notify the Party to whom performance is due by telephone (to be confirmed in writing within two (2) days of the inception of such delay) and describe at a reasonable level of detail the circumstances causing such delay.

9.3    If a Force Majeure Event substantially prevents, hinders, or delays Carrier’s performance for more than thirty (30) consecutive days, then Vonage may terminate this Agreement in its entirety without liability to Carrier as of a date specified by Vonage in a notice of termination to Carrier. Carrier shall not have the right to any additional payments from Vonage for costs or expenses incurred by Carrier as a result of any Force Majeure Event.

12.ASSIGNMENT. The Agreement shall accrue to the benefit of and be binding upon the Parties hereto and any permitted assignee, purchaser or any successor entity into which a Party has been merged or consolidated or to which a Party has sold or transferred all or substantially all of its assets. No Party may assign this Agreement without the prior consent of the other Party, whose consent shall not be unreasonably withheld; except that Vonage may assign its rights and obligations under this Agreement without the prior consent of Carrier to an affiliate or related company, or to an entity which acquires all or substantially all of the assets of Vonage, or to a successor in a merger or acquisition of Vonage upon prior notice to Carrier. Any attempted or purported assignment or transfer in contravention of the foregoing is null and void.

13.NOTICE. All notices, requests, demands, and determinations under this Agreement (other than routine operational communications or as otherwise specifically set forth herein), shall be in writing and shall be deemed duly given: (i) when delivered by hand; (ii) when successfully delivered by e-mail; (iii) one (1) business day after being given to an express, overnight courier with a reliable system for tracking delivery; (iv) when sent by confirmed facsimile with a copy delivered by another means specified in this Section; or (v) four (4) business days after the day of mailing, when mailed by U.S. mail, registered or certified mail, return receipt requested, postage prepaid, with respect to clauses (i) through (v) addressed as follows:

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Significant Accounting Policies

Basis of Presentation and Significant Accounting Policies

Nature of Operations

Vonage Holdings Corp. (“Vonage”, “Company”, “we”, “our”, “us”) is incorporated as a Delaware corporation. We are a leading provider of low-cost communications services connecting people through cloud-connected devices worldwide. Customers in the United States represented 93% of our subscriber lines for our broadband telephone replacement services at June 30, 2013, with the balance primarily in Canada and the United Kingdom.

Unaudited Interim Financial Information

The accompanying unaudited interim consolidated financial statements and information have been prepared in accordance with accounting principles generally accepted in the United States and in accordance with the instructions for Form 10-Q. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, these financial statements contain all normal and recurring adjustments considered necessary to present fairly the financial position, results of operations, cash flows, and statement of stockholders’ equity for the periods presented. The results for the three and six months ended June 30, 2013 are not necessarily indicative of the results to be expected for the full year.

These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2012 filed with the Securities and Exchange Commission on February 13, 2013.

Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of Vonage and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.

On an ongoing basis, we evaluate our estimates, including the following:

• the useful lives of property and equipment, software costs, and intangible assets;

• assumptions used for the purpose of determining share-based compensation using the Black-Scholes option pricing model (“Model”), and various other assumptions that we believe to be reasonable; the key inputs for this Model are our stock price at valuation date, exercise price, the dividend yield, risk-free interest rate, life in years, and historical volatility of our common stock; and

• assumptions used in determining the need for, and amount of, a valuation allowance on net deferred tax assets.

We base our estimates on historical experience, available market information, appropriate valuation methodologies, and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.

Revenue Recognition

Revenues consist of telephony services revenues and customer equipment (which enables our telephony services) and shipping revenues. The point in time at which revenues are recognized is determined in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104, Revenue Recognition, and Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition.

At the time a customer signs up for our telephony services, there are the following deliverables:

• Providing equipment, if any, to the customer that enables our telephony services; and

• Providing telephony services.

The equipment is provided free of charge to our customers and in most instances there are no activation fees collected at sign-up. We record the fees collected for shipping the equipment to the customer, if any, as shipping and handling revenue at the time of shipment.

Telephony Services Revenue

Substantially all of our revenues are telephony services revenues, which are derived primarily from monthly subscription fees that customers are charged under our service plans. We also derive telephony services revenues from per minute fees for international calls if not covered under a plan, including applications for mobile devices and other stand-alone products, and for any calling minutes in excess of a customer’s monthly plan limits. Monthly subscription fees are automatically charged to customers’ credit cards, debit cards or electronic check payments ("ECP"), in advance and are recognized over the following month when services are provided. Revenues generated from international calls and from customers exceeding allocated call minutes under limited minute plans are recognized as services are provided, that is, as minutes are used, and are billed to a customer’s credit cards, debit cards or ECP in arrears. As a result of our multiple billing cycles each month, we estimate the amount of revenues earned from international calls and from customers exceeding allocated call minutes under limited minute plans but not billed from the end of each billing cycle to the end of each reporting period and record these amounts as accounts receivable. These estimates are based primarily upon historical minutes and have been consistent with our actual results.

We also provide rebates to customers who purchase their customer equipment from retailers and satisfy minimum service period requirements. These rebates in excess of activation fees are recorded as a reduction of revenues over the service period based upon the estimated number of customers that will ultimately earn and claim the rebates.

In the United States, we charge regulatory, compliance, E-911, and intellectual property-related fees on a monthly basis to defray costs, and to cover taxes that we are charged by the suppliers of telecommunications services. In addition, we charge customers Federal Universal Service Fund (“USF”) fees. We recognize revenue on a gross basis for USF and related fees. We record these fees as revenue when billed. All other taxes are recorded on a net basis.

Customer Equipment and Shipping Revenue

Customer equipment and shipping revenues, comprising an incidental portion of our revenue, derives from revenues from sales of customer equipment to wholesalers or directly to customers for replacement devices, or for upgrading their device at the time of customer sign-up for which we charge an additional fee. In addition, customer equipment and shipping revenues include the fees that customers are charged for shipping their customer equipment to them. Customer equipment and shipping revenues include sales to our retailers, who subsequently resell this customer equipment to customers. Revenues are reduced for payments to retailers and rebates to customers who purchased their customer equipment through these retailers, to the extent of customer equipment and shipping revenues.

Direct Cost of Telephony Services

Direct cost of telephony services consists primarily of direct costs that we pay to third parties in order to provide telephony services. These costs include access and interconnection charges that we pay to other telephone companies to terminate domestic and international phone calls on the public switched telephone network. In addition, these costs include the cost to lease phone numbers, to co-locate in other telephone companies’ facilities, to provide enhanced emergency dialing capabilities to transmit 911 calls, and to provide local number portability. These costs also include taxes that we pay on telecommunications services from our suppliers or are imposed by government agencies such as Federal USF and royalties for use of third parties’ intellectual property. These costs do not include indirect costs such as depreciation and amortization, payroll, and facilities costs. Our presentation of direct cost of telephony services may not be comparable to other similar companies.

Direct Cost of Goods Sold

Direct cost of goods sold consists primarily of costs that we incur when a customer signs up for our service. These costs include the cost of customer equipment for customers who subscribe through the direct sales channel in excess of activation fees. In addition, these costs include the amortization of deferred customer equipment, the cost of shipping and handling for customer equipment, the installation manual that accompanies the customer equipment, and the cost of certain promotions.

Development Expenses

Costs for research, including predevelopment efforts prior to establishing technological feasibility of software expected to be marketed, are expensed as incurred. Development costs are capitalized when technological feasibility has been established and anticipated future revenues support the recoverability of the capitalized amounts. Capitalization stops when the product is available for general release to customers. Due to the short time period between achieving technological feasibility and product release and the insignificant amount of costs incurred during such periods, we have not capitalized any software development, and have expensed these costs as incurred. These costs are included in selling, general and administrative expense.

Cash and Cash Equivalents

We maintain cash with several investment grade financial institutions. Highly liquid investments, which are readily convertible into cash, with original maturities of three months or less, are recorded as cash equivalents.

Certain Risks and Concentrations

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash equivalents and accounts receivable. They are subject to fluctuations in both market value and yield based upon changes in market conditions, including interest rates, liquidity, general economic conditions, and conditions specific to the issuers. Accounts receivable are typically unsecured and are derived from revenues earned from customers primarily located in the United States. A portion of our accounts receivable represents the timing difference between when a customer’s credit card is billed and the subsequent settlement of that transaction with our credit card processors. This timing difference is generally three days for substantially all of our credit card receivables. We have never experienced any accounts receivable write-offs due to this timing difference. In addition, we collect subscription fees in advance, minimizing our accounts receivable and bad debt exposure. If a customer’s credit card, debit card or ECP is declined, we generally suspend international calling capabilities as well as their ability to incur domestic usage charges in excess of their plan minutes. If the customer’s credit card, debit card or ECP could not be successfully processed during three billing cycles (i.e., the current and two subsequent monthly billing cycles), we terminate the account. In addition, we automatically charge any per minute fees to our customers’ credit card, debit card or ECP monthly in arrears. To further mitigate our bad debt exposure, a customer’s credit card, debit card or ECP will be charged in advance of their monthly billing if their international calling or overage charges exceed a certain dollar threshold.

Inventory

Inventory consists of the cost of customer equipment and is stated at the lower of cost or market, with cost determined using the average cost method. We provide an inventory allowance for customer equipment that has been returned by customers but may not be able to be re-issued to new customers or returned to the manufacturer for credit.

Property and Equipment

Property and equipment includes acquired assets and those accounted for under capital leases and consist principally of network equipment and computer hardware, furniture, software, and leasehold improvements. In addition, the lease of our corporate headquarters has been accounted for as a capital lease and is included in property and equipment. Network equipment and computer hardware and furniture are stated at cost with depreciation provided using the straight-line method over the estimated useful lives of the related assets, which range from three to five years. Leasehold improvements are amortized over their estimated useful life of the related assets or the life of the lease, whichever is shorter. The cost of renewals and substantial improvements is capitalized while the cost of maintenance and repairs is charged to operating expenses as incurred.

Our network equipment and computer hardware, which consists of routers, gateways, and servers that enable our telephony services, is subject to technological risks and rapid market changes due to new products and services and changing customer demand. These changes may result in future adjustments to the estimated useful lives or the carrying value of these assets, or both.

Software Costs

We capitalize certain costs, such as purchased software and internally developed software that we use for customer acquisition and customer care automation tools, in accordance with FASB ASC 350-40, “Internal-Use Software”. Computer software is stated at cost less accumulated amortization and the estimated useful life is two to five years.

As previously disclosed, we experienced delays and incremental costs during the course of the development and implementation of a new billing and ordering system by Amdocs Software Systems Limited and Amdocs, Inc. (collectively, "Amdocs") and the transition of customers to the system. We conducted discussions with Amdocs to resolve the issues associated with the billing and ordering system. Based on these discussions, and after our consideration of the progress made improving our overall IT infrastructure, the incremental time and costs to develop and implement the Amdocs system, as well as the expected reduction in capital expenditures, in June 2012 we and Amdocs determined that terminating the program was in the best interest of both parties. On July 30, 2012, we entered into a Settlement Agreement with Amdocs terminating the related license agreement. As a result, we wrote off our investment in the system of $25,262, net of settlement amounts to us, in the second quarter of 2012. This charge is recorded as loss from abandonment of software assets in the statement of operations.

Intangible Assets

Intangible assets acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.

Patents and Patent Licenses

Patent rights acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.

Long-Lived Assets

We evaluate impairment losses on long-lived assets used in operations when events and changes in circumstances indicate that the assets might be impaired. If our review indicates that the carrying value of an asset will not be recoverable, based on a comparison of the carrying value of the asset to the undiscounted future cash flows, the impairment will be measured by comparing the carrying value of the asset to its fair value. Fair value will be determined based on quoted market values, discounted cash flows or appraisals. Impairments of long-lived assets used in operations are recorded in the statement of operations as part of depreciation expense.

Debt Related Costs

Costs incurred in raising debt are deferred and amortized as interest expense using the effective interest method over the life of the debt.

Derivatives

We do not hold or issue derivative instruments for trading purposes. However, in accordance with FASB ASC 815, “Derivatives and Hedging” (“FASB ASC 815”), we review our contractual obligations to determine whether there are terms that possess the characteristics of derivative financial instruments that must be accounted for separately from the financial instrument in which they are embedded. We would recognize these features, if any, as liabilities in our consolidated balance sheet at fair value each period and would recognize any change in the fair value in our statement of operations in the period of change. We would estimate the fair value of these liabilities using available market information and appropriate valuation methodologies.

Income Taxes

We recognize deferred tax assets and liabilities at enacted income tax rates for the temporary differences between the financial reporting bases and the tax bases of our assets and liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. Our net deferred tax assets primarily consist of net operating loss carry forwards (“NOLs”). We are required to record a valuation allowance against our net deferred tax assets to the extent we conclude that it is more likely than not that taxable income generated in the future will be insufficient to utilize the future income tax benefit from our net deferred tax assets (namely, the NOLs) prior to expiration. In the fourth quarter of 2011, we concluded that it was more likely than not that taxable income in the future would be sufficient to utilize a significant portion of the future income tax benefit from our net deferred tax assets (namely, the NOLs) prior to expiration and we released $325,601 of the valuation allowance. We periodically review this conclusion, which requires significant management judgment. In the future, if available evidence changes our conclusions, we will make an adjustment to the related valuation allowance and income tax expense at that time. The June 30, 2012 effective rate is less than the federal statutory rate due, in part, to our Canadian operations and certain discrete period items, which primarily consisted of adjustments related to stock compensation, including a non-cash deferred tax adjustment totaling $4,077 for certain stock compensation previously considered nondeductible under Section 162(m) of the Internal Revenue Code. The 2013 estimated annual effective tax rate is expected to approximate 41%, but may fluctuate due to the timing of other discrete period transactions.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution.

We have not had any unrecognized tax benefits. We recognize interest and penalties accrued related to unrecognized tax benefits as components of our income tax provision. We have not had any interest and penalties accrued related to unrecognized tax benefits.

Fair Value of Financial Instruments

Effective January 1, 2008, we adopted FASB ASC 820-10-25, “Fair Value Measurements and Disclosures”. This standard establishes a framework for measuring fair value and expands disclosure about fair value measurements. We did not elect fair value accounting for any assets and liabilities allowed by FASB ASC 825, “Financial Instruments”.

FASB ASC 820-10 defines fair value as the amount that would be received for an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC 820-10 also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. FASB ASC 820-10 describes the following three levels of inputs that may be used:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets and liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data.

Level 3: Unobservable inputs when there is little or no market data available, thereby requiring an entity to develop its own assumptions. The fair value hierarchy gives the lowest priority to Level 3 inputs.

Fair Value of Other Financial Instruments

The carrying amounts of our financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, approximate fair value because of their short maturities. The carrying amounts of our capital leases approximate fair value of these obligations based upon management’s best estimates of interest rates that would be available for similar debt obligations at June 30, 2013 and December 31, 2012. We believe the fair value of our debt at June 30, 2013 was approximately the same as its carrying amount as market conditions, including available interest rates, credit spread relative to our credit rating, and illiquidity, remain relatively unchanged from the issuance date of our debt on February 11, 2013 for a similar debt instrument.

Foreign Currency

Generally, the functional currency of our non-United States subsidiaries is the local currency. The financial statements of these subsidiaries are translated to United States dollars using month-end rates of exchange for assets and liabilities, and average rates of exchange for revenues, costs, and expenses. Translation gains and losses are deferred and recorded in accumulated other comprehensive income as a component of stockholders’ equity.

Share-Based Compensation

We account for share-based compensation in accordance with FASB ASC 718, “Compensation-Stock Compensation”. Under the fair value recognition provisions of this pronouncement, share-based compensation cost is measured at the grant date based on the fair value of the award, reduced as appropriate based on estimated forfeitures, and is recognized as expense over the applicable vesting period of the stock award using the accelerated method. The excess tax benefit associated with stock compensation deductions have not been recorded in additional paid-in capital. When evaluating whether an excess tax benefit has been realized, share based compensation deductions are not considered realized until NOLs are no longer sufficient to offset taxable income. Such excess tax benefits will be recorded when realized.

Earnings per Share

Net income per share has been computed according to FASB ASC 260, “Earnings per Share”, which requires a dual presentation of basic and diluted earnings per share (“EPS”). Basic EPS represents net income divided by the weighted average number of common shares outstanding during a reporting period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock, including stock options and restricted stock units under our 2001 Stock Incentive Plan and 2006 Incentive Plan, were exercised or converted into common stock. The dilutive effect of outstanding stock options and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method. In applying the treasury stock method for stock-based compensation arrangements, the assumed proceeds are computed as the sum of the amount the employee must pay upon exercise and the amounts of average unrecognized compensation cost attributed to future services.

The following table sets forth the computation for basic and diluted net income per share for the three and six months ended June 30, 2013 and 2012:

	Three Months Ended					Six Months Ended

Comprehensive Income (Loss)

Comprehensive income (loss) consists of net income and other comprehensive items. Other comprehensive items include foreign currency translation adjustments.

Reclassifications

Certain reclassifications have been made to prior years’ financial statements in order to conform to the current year’s presentation. The reclassifications had no impact on net earnings previously reported.

Litigation

IP Matters

Bear Creek Technologies, Inc. On February 22, 2011, Bear Creek Technologies, Inc. (“Bear Creek”) filed a lawsuit against Vonage Holdings Corp., Vonage America, Inc., and Vonage Marketing LLC in the United States District Court for the Eastern District of Virginia (Norfolk Division) alleging that Vonage's products and services are covered by United States Patent No. 7,889,722, entitled “System for Interconnecting Standard Telephony Communications Equipment to Internet Protocol Networks” (the “722 Patent”). The suit also named numerous other defendants, including Verizon Communications, Inc., Comcast Corporation, Time-Warner Cable, Inc., AT&T, Inc., and T-Mobile USA Inc. On August 17, 2011, the Court dismissed Bear Creek's case against the Vonage entities, as well as all the other defendants, except for one defendant. Later, on August 17, 2011, Bear Creek re-filed its complaint concerning the '722 Patent in the United States District Court for the District of Delaware against the same Vonage entities. In its Delaware complaint, Bear Creek alleges that Vonage is infringing one or more claims of the '722 Patent. In addition, Bear Creek alleges that Vonage is contributing to and inducing infringement of one or more claims of the '722 Patent. On September 28, 2011, Vonage filed a motion to dismiss Bear Creek's claims for induced, contributory, and willful infringement, which was denied on September 27, 2012. On January 25, 2012, Bear Creek filed a motion with the United States Judicial Panel on Multidistrict Litigation seeking to transfer and consolidate its litigation against Vonage with thirteen separate actions Bear Creek filed in the U.S. District Courts for Delaware and the Eastern District of Virginia. On May 2, 2012, the Multidistrict Litigation Panel granted Bear Creek's motion and ordered the coordination or consolidation for pretrial proceedings of all fourteen actions in the U.S. District Court for the District of Delaware. On October 11, 2012, Vonage filed an answer to Bear Creek's complaint, including counterclaims of non-infringement and invalidity of the '722 patent. On November 5, 2012, Bear Creek filed an answer to Vonage's counterclaims. On March 1, 2013, several defendants including Vonage moved the Court to stay the case pending resolution of the reexamination of the '722 patent requested by Cisco Systems, Inc. (“Cisco”) as described below; the motion was granted on July 17, 2013, and the case is now stayed pending the resolution of the reexamination.

On March 8, 2012, a third-party requested the United States Patent and Trademark Office ("USPTO") to reexamine the validity of the asserted '722 Patent.  The USPTO granted the request on April 26, 2012, and subsequently issued an initial Office Action rejecting all of the '722 Patent claims. After reconsideration based on statements made by the patentee, the USPTO on September 19, 2012, reversed its initial rejection, and confirmed all claims as patentable over the references cited in the reexamination request. A second request for reexamination of the '722 Patent was filed on September 12, 2012, by Cisco, challenging the validity of the '722 Patent. Cisco's request was granted by the USPTO on November 28, 2012.  On March 26, 2013, the USPTO issued an Office Action rejecting all claims of the '722 patent as invalid. Bear Creek responded to the Office Action on May 28, 2013, requesting withdrawal of the USPTO's rejection.  Cisco responded to Bear Creek's submission on June 26, 2013. A third request for reexamination of the '722 Patent was filed on September 14, 2012, and the USPTO denied this request on December 6, 2012.

OpinionLab, Inc. On July 18, 2012, OpinionLab, Inc. (“OpinionLab”) filed a lawsuit against IPerceptions, Inc. and IPerceptions US, Inc. (collectively, “IPerceptions”) in the United States District Court for the District of Northern Illinois (Eastern Division) alleging claims of patent infringement, breach of contract, misappropriation of trade secrets, and tortious interference with business expectancy. On August 16, 2012, OpinionLab filed an amended complaint, adding Vonage Marketing LLC and Vonage Holdings Corp. as defendants, and alleging that Vonage's products and services are covered by United States Patent Nos. 6,421,724, 6,606,581, 6,928,392, 7,085,820, 7,370,285, 8,024,668, and 8,041,805. OpinionLab alleged direct, indirect and willful infringement by Vonage. IPerceptions, the supplier to Vonage of the accused product in this lawsuit, has agreed to fully defend and indemnify Vonage in this lawsuit. On September 11, 2012, IPerceptions and Vonage each moved to dismiss OpinionLab's indirect and willful patent infringement claims. The motions were denied on November 8, 2012. Vonage answered the complaint on December 7, 2012. On July 11, 2013, the Court issued an order setting the case schedule.

RPost Holdings, Inc. On August 24, 2012, RPost Holdings, Inc., RPost Communications Limited, and RMail Limited (collectively, “RPost”) filed a lawsuit against StrongMail Systems, Inc. (“StrongMail”) in the United States District Court for the Eastern District of Texas (Marshall Division) alleging that StrongMail's products and services, including its electronic mail marketing services, are covered by United States Patent Nos. 8,224,913, 8,209,389, 8,161,104, 7,966,372, and 6,182,219. On January 16, 2013, StrongMail moved the Court to transfer the venue of the lawsuit to the Northern District of California. That motion is now fully-briefed and pending before the Court. On February 11, 2013, RPost filed an amended complaint, adding 27 new defendants, including Vonage America Inc. RPost's amended complaint alleges willful infringement of the RPost patents by Vonage and each of the other new defendants because they are customers of StrongMail. RPost first served Vonage with the lawsuit on March 8, 2013. StrongMail has agreed to fully defend and indemnify Vonage in this lawsuit. Vonage answered the complaint on May 7, 2013.

From time to time, in addition to those identified above, we are subject to legal proceedings, claims, investigations, and proceedings in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. From time to time we receive letters or other communications from third parties inviting us to obtain patent licenses that might be relevant to our business or alleging that our services infringe upon third party patents or other intellectual property. In accordance with generally accepted accounting principles, we make a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss or range of loss can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. We believe that we have valid defenses with respect to the legal matters pending against us and are vigorously defending these matters. Given the uncertainty surrounding litigation and our inability to assess the likelihood of a favorable or unfavorable outcome in the above noted matters and our inability to reasonably estimate the amount of loss or range of loss, it is possible that the resolution of one or more of these matters could have a material adverse effect on our consolidated financial position, cash flows or results of operations.

Regulation

Telephony services are subject to a broad spectrum of state and federal regulations. Because of the uncertainty over whether Voice over Internet Protocol (“VoIP”) should be treated as a telecommunications or information service, we have been involved in a substantial amount of state and federal regulatory activity. Implementation and interpretation of the existing laws and regulations is ongoing and is subject to litigation by various federal and state agencies and courts. Due to the uncertainty over the regulatory classification of VoIP service, there can be no assurance that we will not be subject to new regulations or existing regulations under new interpretations, and that such change would not introduce material additional costs to our business.

Federal - Net Neutrality

Clear and enforceable net neutrality rules would make it more difficult for broadband Internet service providers to block or discriminate against Vonage service. Also explicitly applying net neutrality rules to wireless broadband Internet service could create greater opportunities for VoIP applications that run on wireless broadband Internet service. In October 2009, the FCC proposed the adoption of enforceable net neutrality rules for both wired and wireless broadband Internet service providers. The proposed rules would prohibit wired and wireless broadband Internet service providers from blocking or hindering lawful content, applications, or services and from unreasonably discriminating when transmitting lawful network traffic. In addition, broadband Internet service providers would have to publicly disclose certain information about their network management practices. In December 2010, the FCC adopted enforceable net neutrality rules based on its October 2009 proposal. All of the proposed rules in the October 2009 proposal applied to wired broadband Internet providers. The FCC applied some but not all of the proposed rules to wireless broadband service. Wireless broadband Internet services providers are prohibited from blocking or hindering voice or video applications that compete with the broadband Internet service provider's voice or video services. Wireless providers are also subject to transparency requirements, but they are not subject to the prohibition on unreasonable discrimination that applies to wired broadband Internet services providers. Final rules were filed in the Federal Register in September 2011. Shortly thereafter, a number of parties filed appeals of the rules in various federal circuit courts; some alleging that the FCC lacks authority to apply net neutrality rules to broadband service providers and some alleging that the rules did not go far enough. The D.C. Circuit Court of Appeals was selected by lottery to decide the appeals and the appeals alleging that the rules did not go far enough were dropped. The appeals alleging that the FCC lacks authority to apply the rules are pending.

Federal - Intercarrier Compensation

On February 9, 2011, the FCC released a Notice of Proposed Rulemaking on reforming universal service and the intercarrier compensation (“ICC”) system that governs payments between telecommunications carriers primarily for terminating traffic. In particular, the FCC indicated that it has never determined the ICC obligations for VoIP service and sought comment on a number of proposals for how VoIP should be treated in the ICC system. The FCC's adoption of an ICC proposal will impact Vonage's costs for telecommunications services. On October 27, 2011, the FCC adopted an order reforming universal service and ICC. The FCC order provides that VoIP originated calls will be subject to interstate access charges for long distance calls and reciprocal compensation for local calls that terminate to the public switched telephone network (“PSTN”). It also subjected PSTN originated traffic directed to VoIP subscribers to similar ICC obligations. The termination charges for all traffic, including VoIP originated traffic, will transition over several years to a bill and keep arrangement (i.e., no termination charges). Numerous parties filed appeals of the FCC order in multiple federal circuit courts of appeal. The 10th Circuit Court of Appeals was selected by lottery to decide the appeals. The appeals are pending.

Federal - Universal Service Contribution Reform

On April 30, 2012, the FCC released a Further Notice of Proposed Rulemaking on reforming federal universal service fund (“USF”) contributions. Currently USF contributions are assessed on the interstate and international revenue of traditional telephone carriers and interconnected VoIP providers like Vonage. The level of USF assessments on these providers has been going up over time because of decreases in the revenue subject to assessment due to substitution of non-assessable services such as non-interconnected VoIP services. If the FCC does reform USF contributions, it is likely that Vonage's contribution burden will decline.

Federal - Rural Call Completion Issues

On February 7, 2013, the FCC released a Notice of Proposed Rulemaking on rural call completion issues. The Notice of Proposed Rulemaking proposes new detailed reporting requirements to gauge rural call completion performance. Rural carriers have argued that VoIP provider call completion performance to rural areas is generally poor. We could be subject to an FCC enforcement action in the future in the event the FCC took the position that our rural call completion performance is inadequate.

Federal - Numbering Rights

On April 18, 2013, the FCC issued a Notice of Proposed Rulemaking (NPRM) that proposes to modify FCC rules to allow VoIP providers to directly access telephone numbers.  In addition, the FCC granted a waiver from its existing rules to allow Vonage to conduct a trial of direct access to telephone numbers.  The trial will allow the FCC to obtain real-world data on direct access to telephone numbers by VoIP providers to inform consideration of the NPRM.  Direct access to telephone numbers would facilitate IP to IP interconnection, which may allow VoIP providers to provide higher quality, lower cost services, promote the deployment of innovative new voice services, and experience reductions in the cost of telephony services. Vonage is currently conducting a trial of direct access to telephone numbers in the Atlanta, Boston, and Phoenix markets.

Pakistan Termination Rate Increase

On October 1, 2012, Pakistani carriers formed the International Clearing House (ICH). This cartel subsequently took action to increase the cost to terminate international calls to Pakistan by approximately 500 percent.  As a result of the implementation of higher termination costs, Vonage was forced to remove Pakistan from unlimited calling in its Vonage World plan.  Vonage filed a petition at the FCC, shortly after the ICH rates became effective, seeking an order prohibiting U.S. carriers from paying the new higher ICH rates.  On March 5, 2013, the FCC issued an order that prohibits U.S. carriers from paying more than the prevailing termination rate prior to the implementation of the ICH rates.  In addition to the Vonage challenge in the U.S., a Pakistani carrier challenged the ICH action under Pakistani competition law.  After the trial court found that the ICH violated Pakistani competition law, the Supreme Court of Pakistan overturned the trial court decision and remanded the case to the Competition Commission of Pakistan (CCP).  On April 30, 2013, the CCP issued an order that holds that the ICH violates Pakistani competition law.  On May 9, 2013, the Sindh High Court temporarily suspended the CCP order while the court considers constitutional challenges to the order made by several Pakistani carriers. Despite favorable action by both U.S. and Pakistani authorities, it is currently unclear if or how long it will take for international termination rates in Pakistan to return to a more competitive level.

State Telecommunications Regulation

In general, the focus of interconnected VoIP telecommunications regulation is at the federal level. On November 12, 2004, the FCC issued a declaratory ruling providing that our service is subject to federal regulation and preempted the Minnesota Public Utilities Commission from imposing certain of its regulations on us. The FCC's decision was based on its conclusion that our service is interstate in nature and cannot be separated into interstate and intrastate components. On March 21, 2007, the United States Court of Appeals for the 8th Circuit affirmed the FCC's declaratory ruling preempting state regulation of our service. The 8th Circuit found that it is impossible for us to separate our interstate traffic from our intrastate traffic because of the nomadic nature of the service. As a result, the 8th Circuit held that it was reasonable for the FCC to preempt state regulation of our service. The 8th Circuit was clear, however, that the preemptive effect of the FCC's declaratory ruling may be reexamined if technological advances allow for the separation of interstate and intrastate components of the nomadic VoIP service. Therefore, the preemption of state authority over our service under this ruling generally hinges on the inability to separate the interstate and intrastate components of the service.While this ruling does not exempt us from all state oversight of our service, it effectively prevents state telecommunications regulators from imposing certain burdensome and inconsistent market entry requirements and certain other state utility rules and regulations on our service. State regulators continue to probe the limits of federal preemption in their attempts to apply state telecommunications regulation to interconnected VoIP service. On July 16, 2009, the Nebraska Public Service Commission and the Kansas Corporation Commission filed a petition with the FCC seeking a declaratory ruling or, alternatively, adoption of a rule declaring that state authorities may apply universal service funding requirements to nomadic VoIP providers. We participated in the FCC proceedings on the petition. On November 5, 2010, the FCC issued a declaratory ruling that allowed states to assess state USF on nomadic VoIP providers on a going forward basis provided that the states comply with certain conditions to ensure that imposing state USF does not conflict with federal law or policy. We expect that state public utility commissions and state legislators will continue their attempts to apply state telecommunications regulations to nomadic VoIP service.

Stand-by Letters of Credit

We had stand-by letters of credit totaling $4,302 and $5,558, as of June 30, 2013 and December 31, 2012, respectively.

End-User Commitments

We are obligated to provide telephone services to our registered end-users. The costs related to the potential utilization of minutes sold are expensed as incurred. Our obligation to provide this service is dependent on the proper functioning of systems controlled by third-party service providers. We do not have a contractual service relationship with some of these providers.

Vendor Commitments

We have committed to purchase international carrier services from a vendor. We have committed to pay this vendor approximately $39,000 in 2013, $78,000 in 2014 and 2015, and $39,000 in 2016, respectively.

We have committed to purchase energy supply from a vendor. We have committed to pay this vendor approximately $600 in 2013, $1,100 in 2014, and $500 in 2015, respectively.

State and Municipal Taxes

In accordance with generally accepted accounting principles, we make a provision for a liability for taxes when it is both probable that a liability has been incurred and the amount of the liability or range of liability can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. For a period of time, we did not collect or remit state or municipal taxes (such as sales, excise, utility, use, and ad valorem taxes), fees or surcharges (“Taxes”) on the charges to our customers for our services, except that we historically complied with the New Jersey sales tax. We have received inquiries or demands from a number of state and municipal taxing and 911 agencies seeking payment of Taxes that are applied to or collected from customers of providers of traditional public switched telephone network services. Although we have consistently maintained that these Taxes do not apply to our service for a variety of reasons depending on the statute or rule that establishes such obligations, we are now collecting and remitting sales taxes in certain of those states including a number of states that have changed their statutes to expressly include VoIP. In addition, many states address how VoIP providers should contribute to support public safety agencies, and in those states we remit fees to the appropriate state agencies. We could also be contacted by state or municipal taxing and 911 agencies regarding Taxes that do explicitly apply to VoIP and these agencies could seek retroactive payment of Taxes. As such, we have a reserve of $2,122 as of June 30, 2013 as our best estimate of the potential tax exposure for any retroactive assessment. We believe the maximum estimated exposure for retroactive assessments is approximately $5,000 as of June 30, 2013.

Stockholders' Equity Note [Abstract]

Common Stock

 Common Stock

Net Operating Loss Rights Agreement

On June 7, 2012, we entered into a Tax Benefits Preservation Plan ("Preservation Plan") designed to preserve stockholder value and tax assets. Our ability to use our tax attributes to offset tax on U.S. taxable income would be substantially limited if there were an "ownership change" as defined under Section 382 of the U.S. Internal Revenue Code. In general, an ownership change would occur if one or more "5-percent shareholders," as defined under Section 382, collectively increase their ownership in us by more than 50 percent over a rolling three-year period.

In connection with the adoption of the Preservation Plan, our board of directors declared a dividend of one preferred share purchase right for each outstanding share of the Company’s common stock. The preferred share purchase rights were distributed to stockholders of record as of June 18, 2012, as well as to holders of the Company's common stock issued after that date, but will only be activated if certain triggering events under the Preservation Plan occur.

Under the Preservation Plan, preferred share purchase rights will work to impose significant dilution upon any person or group which acquires beneficial ownership of 4.9% or more of the outstanding common stock, without the approval of our board of directors, from and after June 7, 2012. Stockholders that own 4.9% or more of the outstanding common stock as of the opening of business on June 7, 2012, will not trigger the preferred share purchase rights so long as they do not (i) acquire additional shares of common stock or (ii) fall under 4.9% ownership of common stock and then re-acquire shares that in the aggregate equal 4.9% or more of the common stock.

The Preservation Plan was set to expire no later than the close of business June 7, 2013, unless extended by our board of directors. On April 4, 2013, after consultation with our advisors, our board of directors determined to extend the Preservation Plan through June 7, 2015, subject to ratification of the extension by stockholders at the Vonage 2013 annual meeting of stockholders. On June 6, 2013, at the Vonage 2013 annual meeting of stockholders, stockholders ratified the extension of the Preservation Plan through June 7, 2015.

Common Stock Repurchases

On July 25, 2012, our board of directors authorized a program to repurchase up to $50,000 of Vonage common stock (the "$50,000 repurchase program") through December 31, 2013. The specific timing and amount of repurchases would vary based on available capital resources and other financial and operational performance, market conditions, securities law limitations, and other factors. The repurchases would be made using our cash resources.

We repurchased the following shares of common stock with cash resources under the $50,000 repurchase program during the three and six months ended June 30, 2013:

	Three Months Ended		Six Months Ended
	June 30,		June 30,
	2013		2013
Shares of common stock repurchased	—		2,189
Value of common stock repurchased	$	—	$	5,374

On February 7, 2013, our board of directors discontinued the remainder of our existing $50,000 repurchase program effective at the close of business on February 12, 2013 with $16,682 of availability remaining, and authorized a new program to repurchase up to $100,000 of Vonage common stock (the "$100,000 repurchase program") by December 31, 2014. The specific timing and amount of repurchases will vary based on available capital resources and other financial and operational performance, market conditions, securities law limitations, and other factors. The repurchases will be made using our cash resources. The $100,000 repurchase program may be suspended or discontinued at any time without prior notice.

We repurchased the following shares of common stock with cash resources under the $100,000 repurchase program during the three and six months ended June 30, 2013*:

	Three Months Ended		Six Months Ended
	June 30,		June 30,
	2013		2013
Shares of common stock repurchased	4,756		8,795
Value of common stock repurchased	$	13,451	$	24,458

* including 220 shares, or $625, of common stock repurchases settled in July 2013; excluding commission of $4.

As of June 30, 2013, approximately $75,542 remained of our $100,000 repurchase program. The repurchase program expires on December 31, 2014 but may be suspended or discontinued at any time without notice.

In any period under either repurchase program, cash used in financing activities related to common stock repurchases may differ from the comparable change in stockholders' equity, reflecting timing differences between the recognition of share repurchase transactions and their settlement for cash.

Stock Option Cancellation

As part of our strategy to build shareholder value and to facilitate our goal of reducing the number of shares of common stock outstanding, on February 19, 2013, we entered into an agreement with our Chief Executive Officer to cancel a total of 4,500 of his vested stock options for $5,463. The payment reflects a discount, in favor of the Company, from the closing price of the common stock on the New York Stock Exchange on February 19, 2013.

July 2011 Financing

On July 29, 2011, we entered into a credit agreement (the "2011 Credit Facility") consisting of an $85,000 senior secured term loan and a $35,000 revolving credit facility. The co-borrowers under the 2011 Credit Facility were our wholly owned subsidiary, Vonage America Inc., and us. Obligations under the 2011 Credit Facility were guaranteed, fully and unconditionally, by our other United States subsidiaries and were secured by substantially all of the assets of each borrower and each of the guarantors.

Use of Proceeds

We used $100,000 of the net available proceeds of the 2011 Credit Facility, plus $31,000 of cash on hand, to retire all of the debt under our prior credit facility entered into in 2010, including a $1,000 prepayment fee to holders of that credit facility. We also incurred $2,697 of fees in connection with the 2011 Credit Facility, which was amortized to interest expense over the life of the debt using the effective interest method.

2013 Financing

On February 11, 2013 we entered into Amendment No. 1 to the 2011 Credit Agreement (as further amended by Amendment No. 2 to our 2011 Credit Facility, the "2013 Credit Facility"). The 2013 Credit Facility consists of a $70,000 senior secured term loan and a $75,000 revolving credit facility. The co-borrowers under the 2013 Credit Facility are our wholly owned subsidiary, Vonage America Inc., and us. Obligations under the 2013 Credit Facility are guaranteed, fully and unconditionally, by our other United States subsidiaries and are secured by substantially all of the assets of each borrower and each of the guarantors. On July 26, 2013 we entered into Amendment No. 2 to our 2011 Credit Agreement, which amends our financial covenant related to our consolidated fixed charge coverage ratio by increasing the amount of restricted payments excluded from such calculation from $50,000 to $80,000.

Use of Proceeds

The net proceeds received of $27,500 from the senior secured term loan and the undrawn revolving credit facility under the 2013 Credit Facility will be used for general corporate purposes. We also incurred $2,009 of fees in connection with the 2013 Credit Facility, which is amortized, along with the unamortized fees of $670 in connection with the 2011 Credit Facility, to interest expense over the life of the debt using the effective interest method.

2013 Credit Facility Terms

The following description summarizes the material terms of the 2013 Credit Facility:

The loans under the 2013 Credit Facility mature in February 2016. Principal amounts under the 2013 Credit Facility are repayable in quarterly installments of $5,833 per quarter for the senior secured term loan. The unused portion of our revolving credit facility incurs a 0.45% commitment fee.

Outstanding amounts under the 2013 Credit Facility, at our option, will bear interest at:

• LIBOR (applicable to one-, two-, three- or six-month periods) plus an applicable margin equal to 3.125% if our consolidated leverage ratio is less than 0.75 to 1.00, 3.375% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 3.625% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last day of each relevant interest period or, if the interest period is longer than 3 months, each day that is three months after the first day of the interest period, or

• the base rate determined by reference to the highest of (a) the federal funds effective rate from time to time plus 0.50%, (b) the prime rate of JPMorgan Chase Bank, N.A., and (c) the LIBOR rate applicable to one month interest periods plus 1.00%, plus an applicable margin equal to 2.125% if our consolidated leverage ratio is less than 0.75 to 1.00, 2.275% if our consolidated leverage ratio is greater than or equal to 0.75 to 1.00 and less than 1.50 to 1.00, and 2.625% if our consolidated leverage ratio is greater than or equal to 1.50 to 1.00, payable on the last business day of each March, June, September, and December and the maturity date of the 2013 Credit Facility.

The 2013 Credit Facility provides greater flexibility to us in funding acquisitions and restricted payments, such as stock buybacks, than the 2011 Credit Facility.

We may prepay the 2013 Credit Facility at our option at any time without premium or penalty. The 2013 Credit Facility is subject to mandatory prepayments in amounts equal to:

• 100% of the net cash proceeds from any non-ordinary course sale or other disposition of our property and assets for consideration in excess of a certain amount subject to customary reinvestment provisions and certain other exceptions and

• 100% of the net cash proceeds received in connection with other non-ordinary course transactions, including insurance proceeds not otherwise applied to the relevant insurance loss.

Subject to certain restrictions and exceptions, the 2013 Credit Facility permits us to obtain one or more incremental term loans and/or revolving credit facilities in an aggregate principal amount of up to $60,000 plus an amount equal to repayments of the senior secured term loan upon providing documentation reasonably satisfactory to the administrative agent, without the consent of the existing lenders under the 2013 Credit Facility. The 2013 Credit Facility includes customary representations and warranties and affirmative covenants of the borrowers. In addition, the 2013 Credit Facility contains customary negative covenants, including, among other things, restrictions on the ability of us and our subsidiaries to consolidate or merge, create liens, incur additional indebtedness, dispose of assets, consummate acquisitions, make investments, and pay dividends and other distributions. We must also comply with the following financial covenants:

• a consolidated leverage ratio of no greater than 2.00 to 1.00;

• a consolidated fixed coverage charge ratio of no less than 1.75 to 1.00 subject to adjustment to exclude up to $80,000 in specified restricted payments;

• minimum cash of $25,000 including the unused portion of the revolving credit facility or $35,000 in the event of certain specified corporate actions; and

• maximum capital expenditures not to exceed $55,000 during any fiscal year, provided that the unused amount of any permitted capital expenditures in any fiscal year may be carried forward to the next following fiscal year; in addition, annual excess cash flow up to $8,000 increases permitted capital expenditures.

As of June 30, 2013, we were in compliance with all covenants, including financial covenants, for the 2013 Credit Facility.

The 2013 Credit Facility contains customary events of default that may permit acceleration of the debt. During the continuance of a payment default, interest will accrue at a default interest rate of 2% above the interest rate which would otherwise be applicable, in the case of loans, and at a rate equal to the rate applicable to base rate loans plus 2%, in the case of all other amounts.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of Vonage and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

Use of Estimates

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and the accompanying notes. Actual results could differ materially from these estimates.

On an ongoing basis, we evaluate our estimates, including the following:

• the useful lives of property and equipment, software costs, and intangible assets;

• assumptions used for the purpose of determining share-based compensation using the Black-Scholes option pricing model (“Model”), and various other assumptions that we believe to be reasonable; the key inputs for this Model are our stock price at valuation date, exercise price, the dividend yield, risk-free interest rate, life in years, and historical volatility of our common stock; and

• assumptions used in determining the need for, and amount of, a valuation allowance on net deferred tax assets.

We base our estimates on historical experience, available market information, appropriate valuation methodologies, and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.

Revenue Recognition

Revenue Recognition

Revenues consist of telephony services revenues and customer equipment (which enables our telephony services) and shipping revenues. The point in time at which revenues are recognized is determined in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104, Revenue Recognition, and Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition.

At the time a customer signs up for our telephony services, there are the following deliverables:

• Providing equipment, if any, to the customer that enables our telephony services; and

• Providing telephony services.

The equipment is provided free of charge to our customers and in most instances there are no activation fees collected at sign-up. We record the fees collected for shipping the equipment to the customer, if any, as shipping and handling revenue at the time of shipment.

Telephony Services Revenue

Substantially all of our revenues are telephony services revenues, which are derived primarily from monthly subscription fees that customers are charged under our service plans. We also derive telephony services revenues from per minute fees for international calls if not covered under a plan, including applications for mobile devices and other stand-alone products, and for any calling minutes in excess of a customer’s monthly plan limits. Monthly subscription fees are automatically charged to customers’ credit cards, debit cards or electronic check payments ("ECP"), in advance and are recognized over the following month when services are provided. Revenues generated from international calls and from customers exceeding allocated call minutes under limited minute plans are recognized as services are provided, that is, as minutes are used, and are billed to a customer’s credit cards, debit cards or ECP in arrears. As a result of our multiple billing cycles each month, we estimate the amount of revenues earned from international calls and from customers exceeding allocated call minutes under limited minute plans but not billed from the end of each billing cycle to the end of each reporting period and record these amounts as accounts receivable. These estimates are based primarily upon historical minutes and have been consistent with our actual results.

We also provide rebates to customers who purchase their customer equipment from retailers and satisfy minimum service period requirements. These rebates in excess of activation fees are recorded as a reduction of revenues over the service period based upon the estimated number of customers that will ultimately earn and claim the rebates.

In the United States, we charge regulatory, compliance, E-911, and intellectual property-related fees on a monthly basis to defray costs, and to cover taxes that we are charged by the suppliers of telecommunications services. In addition, we charge customers Federal Universal Service Fund (“USF”) fees. We recognize revenue on a gross basis for USF and related fees. We record these fees as revenue when billed. All other taxes are recorded on a net basis.

Customer Equipment and Shipping Revenue

Customer equipment and shipping revenues, comprising an incidental portion of our revenue, derives from revenues from sales of customer equipment to wholesalers or directly to customers for replacement devices, or for upgrading their device at the time of customer sign-up for which we charge an additional fee. In addition, customer equipment and shipping revenues include the fees that customers are charged for shipping their customer equipment to them. Customer equipment and shipping revenues include sales to our retailers, who subsequently resell this customer equipment to customers. Revenues are reduced for payments to retailers and rebates to customers who purchased their customer equipment through these retailers, to the extent of customer equipment and shipping revenues.

Direct Cost of Telephony Services

Direct Cost of Telephony Services

Direct cost of telephony services consists primarily of direct costs that we pay to third parties in order to provide telephony services. These costs include access and interconnection charges that we pay to other telephone companies to terminate domestic and international phone calls on the public switched telephone network. In addition, these costs include the cost to lease phone numbers, to co-locate in other telephone companies’ facilities, to provide enhanced emergency dialing capabilities to transmit 911 calls, and to provide local number portability. These costs also include taxes that we pay on telecommunications services from our suppliers or are imposed by government agencies such as Federal USF and royalties for use of third parties’ intellectual property. These costs do not include indirect costs such as depreciation and amortization, payroll, and facilities costs. Our presentation of direct cost of telephony services may not be comparable to other similar companies.

Direct Cost of Goods Sold

Direct Cost of Goods Sold

Direct cost of goods sold consists primarily of costs that we incur when a customer signs up for our service. These costs include the cost of customer equipment for customers who subscribe through the direct sales channel in excess of activation fees. In addition, these costs include the amortization of deferred customer equipment, the cost of shipping and handling for customer equipment, the installation manual that accompanies the customer equipment, and the cost of certain promotions.

Development Expenses

Development Expenses

Costs for research, including predevelopment efforts prior to establishing technological feasibility of software expected to be marketed, are expensed as incurred. Development costs are capitalized when technological feasibility has been established and anticipated future revenues support the recoverability of the capitalized amounts. Capitalization stops when the product is available for general release to customers. Due to the short time period between achieving technological feasibility and product release and the insignificant amount of costs incurred during such periods, we have not capitalized any software development, and have expensed these costs as incurred. These costs are included in selling, general and administrative expense.

Cash and Cash Equivalents

Cash and Cash Equivalents

We maintain cash with several investment grade financial institutions. Highly liquid investments, which are readily convertible into cash, with original maturities of three months or less, are recorded as cash equivalents.

Certain Risks and Concentrations

Certain Risks and Concentrations

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash equivalents and accounts receivable. They are subject to fluctuations in both market value and yield based upon changes in market conditions, including interest rates, liquidity, general economic conditions, and conditions specific to the issuers. Accounts receivable are typically unsecured and are derived from revenues earned from customers primarily located in the United States. A portion of our accounts receivable represents the timing difference between when a customer’s credit card is billed and the subsequent settlement of that transaction with our credit card processors. This timing difference is generally three days for substantially all of our credit card receivables. We have never experienced any accounts receivable write-offs due to this timing difference. In addition, we collect subscription fees in advance, minimizing our accounts receivable and bad debt exposure. If a customer’s credit card, debit card or ECP is declined, we generally suspend international calling capabilities as well as their ability to incur domestic usage charges in excess of their plan minutes. If the customer’s credit card, debit card or ECP could not be successfully processed during three billing cycles (i.e., the current and two subsequent monthly billing cycles), we terminate the account. In addition, we automatically charge any per minute fees to our customers’ credit card, debit card or ECP monthly in arrears. To further mitigate our bad debt exposure, a customer’s credit card, debit card or ECP will be charged in advance of their monthly billing if their international calling or overage charges exceed a certain dollar threshold.

Inventory

Inventory

Inventory consists of the cost of customer equipment and is stated at the lower of cost or market, with cost determined using the average cost method. We provide an inventory allowance for customer equipment that has been returned by customers but may not be able to be re-issued to new customers or returned to the manufacturer for credit.

Property and Equipment

Property and Equipment

Property and equipment includes acquired assets and those accounted for under capital leases and consist principally of network equipment and computer hardware, furniture, software, and leasehold improvements. In addition, the lease of our corporate headquarters has been accounted for as a capital lease and is included in property and equipment. Network equipment and computer hardware and furniture are stated at cost with depreciation provided using the straight-line method over the estimated useful lives of the related assets, which range from three to five years. Leasehold improvements are amortized over their estimated useful life of the related assets or the life of the lease, whichever is shorter. The cost of renewals and substantial improvements is capitalized while the cost of maintenance and repairs is charged to operating expenses as incurred.

Our network equipment and computer hardware, which consists of routers, gateways, and servers that enable our telephony services, is subject to technological risks and rapid market changes due to new products and services and changing customer demand. These changes may result in future adjustments to the estimated useful lives or the carrying value of these assets, or both.

Software Costs

Software Costs

We capitalize certain costs, such as purchased software and internally developed software that we use for customer acquisition and customer care automation tools, in accordance with FASB ASC 350-40, “Internal-Use Software”. Computer software is stated at cost less accumulated amortization and the estimated useful life is two to five years.

Intangible Assets

Intangible Assets

Intangible assets acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.

Patents and Patent Licenses

Patent rights acquired in the settlement of litigation or by direct purchase are accounted for based upon the fair value of assets received.

Long-Lived Assets

Long-Lived Assets

We evaluate impairment losses on long-lived assets used in operations when events and changes in circumstances indicate that the assets might be impaired. If our review indicates that the carrying value of an asset will not be recoverable, based on a comparison of the carrying value of the asset to the undiscounted future cash flows, the impairment will be measured by comparing the carrying value of the asset to its fair value. Fair value will be determined based on quoted market values, discounted cash flows or appraisals. Impairments of long-lived assets used in operations are recorded in the statement of operations as part of depreciation expense.

Debt Related Costs

Debt Related Costs

Costs incurred in raising debt are deferred and amortized as interest expense using the effective interest method over the life of the debt.

Derivatives

Derivatives

We do not hold or issue derivative instruments for trading purposes. However, in accordance with FASB ASC 815, “Derivatives and Hedging” (“FASB ASC 815”), we review our contractual obligations to determine whether there are terms that possess the characteristics of derivative financial instruments that must be accounted for separately from the financial instrument in which they are embedded. We would recognize these features, if any, as liabilities in our consolidated balance sheet at fair value each period and would recognize any change in the fair value in our statement of operations in the period of change. We would estimate the fair value of these liabilities using available market information and appropriate valuation methodologies.

Income Taxes

Income Taxes

We recognize deferred tax assets and liabilities at enacted income tax rates for the temporary differences between the financial reporting bases and the tax bases of our assets and liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. Our net deferred tax assets primarily consist of net operating loss carry forwards (“NOLs”). We are required to record a valuation allowance against our net deferred tax assets to the extent we conclude that it is more likely than not that taxable income generated in the future will be insufficient to utilize the future income tax benefit from our net deferred tax assets (namely, the NOLs) prior to expiration. In the fourth quarter of 2011, we concluded that it was more likely than not that taxable income in the future would be sufficient to utilize a significant portion of the future income tax benefit from our net deferred tax assets (namely, the NOLs) prior to expiration and we released $325,601 of the valuation allowance. We periodically review this conclusion, which requires significant management judgment. In the future, if available evidence changes our conclusions, we will make an adjustment to the related valuation allowance and income tax expense at that time. The June 30, 2012 effective rate is less than the federal statutory rate due, in part, to our Canadian operations and certain discrete period items, which primarily consisted of adjustments related to stock compensation, including a non-cash deferred tax adjustment totaling $4,077 for certain stock compensation previously considered nondeductible under Section 162(m) of the Internal Revenue Code. The 2013 estimated annual effective tax rate is expected to approximate 41%, but may fluctuate due to the timing of other discrete period transactions.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution.

We have not had any unrecognized tax benefits. We recognize interest and penalties accrued related to unrecognized tax benefits as components of our income tax provision. We have not had any interest and penalties accrued related to unrecognized tax benefits.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Effective January 1, 2008, we adopted FASB ASC 820-10-25, “Fair Value Measurements and Disclosures”. This standard establishes a framework for measuring fair value and expands disclosure about fair value measurements. We did not elect fair value accounting for any assets and liabilities allowed by FASB ASC 825, “Financial Instruments”.

FASB ASC 820-10 defines fair value as the amount that would be received for an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC 820-10 also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. FASB ASC 820-10 describes the following three levels of inputs that may be used:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets and liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data.

Level 3: Unobservable inputs when there is little or no market data available, thereby requiring an entity to develop its own assumptions. The fair value hierarchy gives the lowest priority to Level 3 inputs.

Fair Value of Other Financial Instruments

The carrying amounts of our financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, approximate fair value because of their short maturities. The carrying amounts of our capital leases approximate fair value of these obligations based upon management’s best estimates of interest rates that would be available for similar debt obligations at June 30, 2013 and December 31, 2012. We believe the fair value of our debt at June 30, 2013 was approximately the same as its carrying amount as market conditions, including available interest rates, credit spread relative to our credit rating, and illiquidity, remain relatively unchanged from the issuance date of our debt on February 11, 2013 for a similar debt instrument.

Foreign Currency

Foreign Currency

Generally, the functional currency of our non-United States subsidiaries is the local currency. The financial statements of these subsidiaries are translated to United States dollars using month-end rates of exchange for assets and liabilities, and average rates of exchange for revenues, costs, and expenses. Translation gains and losses are deferred and recorded in accumulated other comprehensive income as a component of stockholders’ equity.

Share-Based Compensation

Share-Based Compensation

We account for share-based compensation in accordance with FASB ASC 718, “Compensation-Stock Compensation”. Under the fair value recognition provisions of this pronouncement, share-based compensation cost is measured at the grant date based on the fair value of the award, reduced as appropriate based on estimated forfeitures, and is recognized as expense over the applicable vesting period of the stock award using the accelerated method. The excess tax benefit associated with stock compensation deductions have not been recorded in additional paid-in capital. When evaluating whether an excess tax benefit has been realized, share based compensation deductions are not considered realized until NOLs are no longer sufficient to offset taxable income. Such excess tax benefits will be recorded when realized.

Earnings per Share

Earnings per Share

Net income per share has been computed according to FASB ASC 260, “Earnings per Share”, which requires a dual presentation of basic and diluted earnings per share (“EPS”). Basic EPS represents net income divided by the weighted average number of common shares outstanding during a reporting period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock, including stock options and restricted stock units under our 2001 Stock Incentive Plan and 2006 Incentive Plan, were exercised or converted into common stock. The dilutive effect of outstanding stock options and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method. In applying the treasury stock method for stock-based compensation arrangements, the assumed proceeds are computed as the sum of the amount the employee must pay upon exercise and the amounts of average unrecognized compensation cost attributed to future services.

Comprehensive Income (Loss)

Comprehensive Income (Loss)

Comprehensive income (loss) consists of net income and other comprehensive items. Other comprehensive items include foreign currency translation adjustments.

Reclassifications

Reclassifications

Certain reclassifications have been made to prior years’ financial statements in order to conform to the current year’s presentation. The reclassifications had no impact on net earnings previously reported.
