NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Basis of Presentation

Interim Financial Statements

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared by VeriSign, Inc. (“Verisign” or the “Company”) in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, do not include all information and notes normally provided in audited financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation have been included. The results of operations for any interim period are not necessarily indicative of, nor comparable to, the results of operations for any other interim period or for a full fiscal year. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes contained in Verisign’s fiscal 2015 Annual Report on Form 10-K (the “2015 Form 10-K”) filed with the SEC on February 19, 2016.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard will become effective for the Company on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The guidance introduces a lessee model that requires most leases to be reported on the balance sheet. This ASU will become effective for the Company on January 1, 2019 and requires the modified retrospective transition method. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment award transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. There are different transition methods for different aspects of the standard. The new standard will be effective for the Company on January 1, 2017 with early adoption permitted. The Company is evaluating the timing of adoption, transition methods and the effect that this ASU will have on its consolidated financial statements and related disclosures.

(1) Included in Accounts payable and accrued liabilities

(2) Included in Other current assets

The fair value of the Company’s investments in money market funds approximates their face value. Such instruments are classified as Level 1 and are included in Cash and cash equivalents. The fair value of the debt securities consisting of U.S. Treasury bills is based on their quoted market prices and are classified as Level 1. Debt securities purchased with original maturities in excess of three months are included in Marketable securities. The fair value of the equity securities of public companies is based on quoted market prices and are classified as Level 1. Investments in equity securities of public companies are included in Marketable securities. The fair value of the Company’s foreign currency forward contracts is based on foreign currency rates quoted by banks or foreign currency dealers and other public data sources.

The Company utilizes a valuation model to estimate the fair value of the contingent interest derivative on the subordinated convertible debentures due 2037 (“the Subordinated Convertible Debentures”). The inputs to the model include stock price, bond price, risk free interest rates, volatility, and credit spread observations. As several significant inputs are not observable, the overall fair value measurement of the derivative is classified as Level 3. The volatility and credit spread assumptions used in the calculation are the most significant unobservable inputs. As of March 31, 2016, the valuation of the contingent interest derivative assumed a volatility rate of approximately 27% and a credit spread of approximately 6%. The fair value of the contingent interest derivative would not have significantly changed using a volatility rate of either 22% or 32%, or a credit spread of either 5% or 7%.

The following table summarizes the change in the fair value of the Company’s contingent interest derivative on the Subordinated Convertible Debentures during the three months ended March 31, 2016 and 2015:

	Three Months Ended March 31,
	2016			2015
	(In thousands)
Beginning balance	$	30,126		$	26,755
Payment of contingent interest	(6,544		)	(5,225		)
Unrealized (gain) loss	(1,065		)	7,019
Ending balance	$	22,517		$	28,549

On February 15, 2016, the Company paid contingent interest of $6.5 million in addition to the normal coupon interest to holders of record of the Subordinated Convertible Debentures as of February 1, 2016. In February 2016, the upside trigger on the Subordinated Convertible Debentures was met for the six month interest period from February 15, 2016 through August 15, 2016. The $6.8 million contingent interest payable in August 2016 is included in the balance of the contingent interest derivative on the Subordinated Convertible Debentures as of March 31, 2016.

The Company’s other financial instruments include cash, accounts receivable, restricted cash, and accounts payable. As of March 31, 2016, the carrying value of these financial instruments approximated their fair value. The fair value of the Company’s Subordinated Convertible Debentures was $3.2 billion as of March 31, 2016. The fair values of the senior notes due 2023 (the “2023 Senior Notes”) and the senior notes due 2025 (the “2025 Senior Notes”) were $759.4 million and $505.6 million, respectively, as of March 31, 2016. The fair values of these debt instruments are based on available market information from public data sources and are classified as Level 2.

Note 5. Stockholders’ Deficit

On February 11, 2016, the Company’s Board of Directors authorized the repurchase of approximately $611.2 million of its common stock, in addition to the $388.8 million remaining available for repurchase under the previous share repurchase program for a total repurchase authorization of up to $1.0 billion of its common stock. The share repurchase program has no expiration date. Purchases made under the program could be effected through open market transactions, block purchases, accelerated share repurchase agreements or other negotiated transactions. During the three months ended March 31, 2016 the Company repurchased 1.8 million shares of its common stock at an average stock price of $82.88 for an aggregate cost of $149.9 million. As of March 31, 2016, $915.8 million remained available for further repurchases under the share repurchase program.

During the three months ended March 31, 2016, the Company placed 0.3 million shares, at an average stock price of $80.44, and for an aggregate cost of $22.4 million, into treasury stock for purposes related to tax withholding upon vesting of Restricted Stock Units (“RSUs”).

Since inception the Company has repurchased 215.0 million shares of its common stock for an aggregate cost of $7.7 billion, which is presented as a reduction of Additional paid-in capital.

Note 6. Calculation of Earnings per Share

The following table presents the computation of weighted-average shares used in the calculation of basic and diluted earnings per share:

	Three Months Ended March 31,
	2016	2015
	(In thousands)
Weighted-average shares of common stock outstanding	109,592	117,139

Unvested RSUs, stock options, and ESPP	916	899
Shares used to compute diluted earnings per share	131,581	133,850

The calculation of diluted weighted average shares outstanding, excludes potentially dilutive securities, the effect of which would have been anti-dilutive, as well as performance based RSUs granted by the Company for which the relevant performance criteria have not been achieved. The number of potential shares excluded from the calculation was not significant in any period presented.

Note 7. Stock-based Compensation

Stock-based compensation is classified in the Condensed Consolidated Statements of Comprehensive Income in the same expense line items as cash compensation. The following table presents the classification of stock-based compensation:

	Three Months Ended March 31,
	2016		2015
	(In thousands)
Cost of revenues	$	1,841	$	1,739

Total stock-based compensation expense	$	11,759		$	10,128

Note 8. Debt and Interest Expense

The following table presents the components of the Company’s interest expense:

	Three Months Ended March 31,
	2016		2015
	(In thousands)
Contractual interest on Subordinated Convertible Debentures	$	10,156	$	10,156
Contractual interest on Senior Notes	15,235		9,037
Amortization of debt discount on the Subordinated Convertible Debentures	2,689		2,477

Note 9. Non-operating Income (Loss), Net

The following table presents the components of Non-operating income (loss), net:

	Three Months Ended March 31,
	2016		2015
	(In thousands)
Unrealized gain (loss) on contingent interest derivative on Subordinated Convertible Debentures	$	1,065	$	(7,019	)
Interest income	1,042		259
Other, net	1,014		1,205
Total non-operating income (loss), net	$	3,121	$	(5,555	)

Unrealized gains and losses on the contingent interest derivative on the Subordinated Convertible Debentures reflect the change in value of the derivative that results primarily from changes in the Company’s stock price.

Note 10. Income Taxes

The following table presents income tax expense and the effective tax rate:

	Three Months Ended March 31,
	2016			2015
	(Dollars in thousands)
Income tax expense	$	33,628		$	28,427
Effective tax rate	24		%	24		%

The effective tax rate for the three months ended March 31, 2016 and 2015 is lower than the statutory federal rate of 35% primarily due to tax benefits from foreign income taxed at lower rates, partially offset by state income taxes.

Deferred tax liabilities as of March 31, 2016 reflect the use of a portion of U.S. foreign tax credits during the three months ended March 31, 2016, and an increase in the deferred tax liability related to the Subordinated Convertible Debentures.

Overview

We are a global provider of domain name registry services and Internet security, enabling Internet navigation for many of the world’s most recognized domain names and providing protection for websites and enterprises around the world. Our Registry Services ensure the security, stability and resiliency of key Internet infrastructure and services, including the .com and .net domains, two of the Internet’s root servers, and the operation of the root zone maintainer function for the core of the Internet’s DNS. Our product suite also includes Security Services, consisting of DDoS Protection Services, iDefense Services, and Managed DNS Services. 

As of March 31, 2016, we had approximately 142.5 million names in the domain name base for .com and .net, our principal registries. The number of domain names registered is largely driven by continued growth in online advertising, e-commerce, and the number of Internet users, which is partially driven by greater availability of Internet access, as well as marketing activities carried out by us and third-party registrars. Growth in the number of domain names under our management may be hindered by certain factors, including overall economic conditions, competition from ccTLDs, the introduction of new gTLDs, and ongoing changes in the Internet practices and behaviors of consumers and businesses. Factors such as the evolving practices and preferences of Internet users, and how they navigate the Internet, as well as the motivation of domain name registrants and how they will manage their investment in domain names, can negatively impact our business and the demand for new domain name registrations and renewals. Revenues from Security Services are not significant in relation to our consolidated revenues.

Business Highlights and Trends

• We recorded revenues of $281.9 million during the three months ended March 31, 2016. This represents an increase of 9% as compared to the same period in 2015.

• On February 1, 2016, the annual fee for a .net domain name registration increased from $6.79 to $7.46 per our agreement with ICANN.

Pursuant to our agreements with ICANN, we make available on our website (at www.Verisign.com/zone) files containing all active domain names registered in the .com and .net registries. At the same website address, we make available a summary of the active zone count registered in the .com and .net registries and the number of .com and .net domain names in the domain name base. The domain name base is the active zone plus the number of domain names that are registered but not configured for use in the respective top level domain zone file plus the number of domain names that are in a client or server hold status. These files and the related summary data are updated at least once per day. The update times may vary each day. The number of domain names provided in this Form 10-Q are as of midnight of the date reported. Information available on, or accessible through, our website is not incorporated herein by reference.

Revenues

Revenues related to our Registry Services are primarily derived from registrations for domain names in the .com and .net domain name registries. We also derive revenues from operating domain name registries for several other TLDs and from providing back-end registry services to a number of TLD registry operators, all of which are not significant in relation to our consolidated revenues. For domain names registered with the .com and .net registries we receive a fee from third-party registrars per annual registration that is fixed pursuant to our agreements with ICANN. Individual customers, called registrants, contract directly with third-party registrars or their resellers, and the third-party registrars in turn register the domain names with Verisign. Changes in revenues are driven largely by changes in the number of new domain name registrations and the renewal rate for existing registrations as well as the impact of new and prior price increases, to the extent permitted by ICANN and the DOC. New registrations and the renewal rate for existing registrations are impacted by continued growth in online advertising, e-commerce, and the number of Internet users, as well as marketing activities carried out by us and third-party registrars. We increased the annual fee for a .net domain name registration from $6.18 to $6.79 on February 1, 2015, and from $6.79 to $7.46 on February 1, 2016. We have the contractual right to increase the fees for .net domain name registrations by up to 10% each year during the term of our .net agreement with ICANN through June 30, 2017. The annual fee for a .com domain name registration is fixed at $7.85 for the duration of the current .com Registry Agreement through November 30, 2018, except that prices may be raised by up to 7% each year due to the imposition of any new Consensus Policy or documented extraordinary expense resulting from an attack or threat of attack on the Security and Stability (each as defined in the .com Registry Agreement) of the DNS, subject to approval of the DOC. We offer promotional marketing programs for our registrars based upon market conditions and the business environment in which the registrars operate. All fees paid to us

13

for .com and .net registrations are in U.S. dollars. Revenues from Security Services are not significant in relation to our total consolidated revenues.

A comparison of revenues is presented below:

	Three Months Ended March 31,
	2016		% Change		2015
	(Dollars in thousands)
Revenues	$	281,876	9	%	$	258,422

The following table compares domain name base for .com and .net managed by our Registry Services business:

	March 31, 2016	% Change		March 31, 2015
Domain name base for .com and .net	142.5 million	7	%	133.0 million

Revenues increased by $23.5 million during the three months ended March 31, 2016, as compared to the same period last year, primarily due to an increase in revenues from the operation of the registries for the .com and .net TLDs. The increase in revenues from the operation of the registries for the .com and .net TLDs was driven by a 7% increase in the domain name base for .com and .net and an increase in the .net domain name registration fees in February 2015 and 2016.

Growth in the domain name base has been primarily driven by continued Internet growth and marketing activities carried out by us and third-party registrars. During the second half of 2015 and the first quarter of 2016 we experienced an increased volume of new domain name registrations primarily from our registrars in China.  The volume of these new registrations has been inconsistent and periodic compared to prior periods, and by the end of the first quarter of 2016, reverted back to a more normalized registration pace. However, ongoing economic uncertainty, competitive pressure from ccTLDs, the introduction of new gTLDs, ongoing changes in Internet practices and behaviors of consumers and business, as well as the motivation of existing domain name registrants and how they will manage their investment in domain names, has limited the rate of growth of the domain name base in recent years and may continue to do so in the remainder of 2016 and beyond.

We expect revenues will continue to increase in the remainder of 2016, as a result of the increased volume of domain registrations during recent quarters, and increases in the .net domain name registration fees in February 2015 and 2016.

Geographic revenues

We generate revenues in the U.S.; Europe, the Middle East and Africa (“EMEA”); China; and certain other countries including Canada, Australia and Japan.

The following table presents a comparison of our geographic revenues:

	Three Months Ended March 31,
	2016		% Change		2015
	(Dollars in thousands)
U.S.	$	164,042	4	%	$	157,508
EMEA	50,956		8	%	47,006
China	31,199		75	%	17,878
Other	35,679		(1	)%	36,030
Total revenues	$	281,876			$	258,422

Revenues for our Registry Services business are attributed to the country of domicile and the respective regions in which our registrars are located, however, this may differ from the regions where the registrars operate or where registrants are located. Revenue growth for each region may be impacted by registrars reincorporating, relocating, or from acquisitions or changes in affiliations of resellers. Revenue growth for each region may also be impacted by registrars domiciled in one region, registering domain names in another region. Although revenues continued to grow in the more mature markets of the U.S. and EMEA, China saw the highest growth rate for the three months ended March 31, 2016 due to the increased volume of new registrations during the second half of 2015 and the first quarter of 2016.

Cost of revenues

Cost of revenues consist primarily of salaries and employee benefits expenses for our personnel who manage the operational systems, depreciation expenses, operational costs associated with the delivery of our services, fees paid to ICANN, customer support and training, consulting and development services, costs of facilities and computer equipment used in these activities, telecommunications expense and allocations of indirect costs such as corporate overhead.

A comparison of cost of revenues is presented below:

	Three Months Ended March 31,
	2016		% Change		2015
	(Dollars in thousands)
Cost of revenues	$	50,582	5	%	$	48,353

Cost of revenues increased by $2.2 million during the three months ended March 31, 2016, as compared to the same period last year, primarily due to a $1.8 million increase in salary and employee benefits expenses. Salary and employee benefits expenses increased primarily due to an increase in average headcount and an increase in bonus expenses.

We expect cost of revenues as a percentage of revenues to decrease slightly during the remainder of 2016 compared to

the three months ended March 31, 2016.

Sales and marketing

Sales and marketing expenses consist primarily of salaries, sales commissions, sales operations and other personnel-related expenses, travel and related expenses, trade shows, costs of lead generation, costs of computer and communications equipment and support services, facilities costs, consulting fees, costs of marketing programs, such as online, television, radio, print and direct mail advertising costs, and allocations of indirect costs such as corporate overhead.

A comparison of sales and marketing expenses is presented below:

	Three Months Ended March 31,
	2016		% Change		2015
	(Dollars in thousands)
Sales and marketing	$	20,027	(11	)%	$	22,382

Sales and marketing expenses decreased by $2.4 million during the three months ended March 31, 2016, as compared to the same period last year, primarily due to a decrease in advertising and consulting expenses. Advertising and consulting expenses decreased primarily due to the timing of our registry channel marketing programs and a decrease in expenses related to our Security Services business.

We expect sales and marketing expenses as a percentage of revenues to increase during the remainder of 2016 compared

to the three months ended March 31, 2016 as the volume of marketing initiatives increases. We expect sales and marketing

expenses as a percent of revenues for full year 2016 to be at comparable levels to 2015.

Research and development

Research and development expenses consist primarily of costs related to research and development personnel, including salaries and other personnel-related expenses, consulting fees, facilities costs, computer and communications equipment, support services used in our service and technology development, and allocations of indirect costs such as corporate overhead.

A comparison of research and development expenses is presented below:

	Three Months Ended March 31,
	2016		% Change		2015
	(Dollars in thousands)
Research and development	$	16,743	(2	)%	$	17,152

Research and development expenses remained consistent during the three months ended March 31, 2016, as compared to the same period last year.

We expect research and development expenses as a percentage of revenues to remain consistent during the remainder of 2016 compared to the three months ended March 31, 2016.

15

General and administrative

General and administrative expenses consist primarily of salaries and other personnel-related expenses for our executive, administrative, legal, finance, information technology and human resources personnel, costs of facilities, computer and communications equipment, management information systems, support services, professional services fees, certain tax and license fees, and bad debt expense, offset by allocations of indirect costs such as facilities and shared services expenses to other cost types.

A comparison of general and administrative expenses is presented below:

	Three Months Ended March 31,
	2016		% Change		2015
	(Dollars in thousands)
General and administrative	$	27,757	6	%	$	26,298

General and administrative expenses increased by $1.5 million during the three months ended March 31, 2016, as compared to the same period last year, primarily due to a $3.3 million increase in salary and employee benefits expenses, including stock-based compensation expenses, partially offset by a $2.0 million expense for certain non-income related taxes in 2015. Salary and employee benefits expenses increased by $2.1 million primarily due to annual salary increases and bonus expenses. Stock-based compensation expenses increased as a result of greater total value of RSUs granted in 2015 and 2016.

We expect general and administrative expenses as a percentage of revenues to remain consistent during the remainder of 2016 compared to the three months ended March 31, 2016.

Interest expense

The following table presents the components of Interest expense:

	Three Months Ended March 31,
	2016		2015
	(In thousands)
Contractual interest on Subordinated Convertible Debentures	$	10,156	$	10,156
Contractual interest on Senior Notes	15,235		9,037
Amortization of debt discount on the Subordinated Convertible Debentures	2,689		2,477
Credit facility fees and other interest expense	724		347
Total interest expense	$	28,804	$	22,017

Contractual interest on Senior Notes increased during the three months ended March 31, 2016 due to $6.6 million of interest expense related to the 2025 Senior Notes which were issued in March 2015. We expect interest expense to remain consistent during the remainder of 2016 as compared to the three months ended March 31, 2016.

Non-operating income (loss), net

The following table presents the components of Non-operating income (loss), net:

	Three Months Ended March 31,
	2016		2015
	(In thousands)
Unrealized gain (loss) on contingent interest derivative on Subordinated Convertible Debentures	$	1,065	$	(7,019	)
Interest income	1,042		259
Other, net	1,014		1,205
Total non-operating income (loss), net	$	3,121	$	(5,555	)

Unrealized gains and losses on the contingent interest derivative on the Subordinated Convertible Debentures reflect the change in value of the derivative that results primarily from changes in our stock price.

16

Income tax expense

The following table presents income tax expense and the effective tax rate:

	Three Months Ended March 31,
	2016			2015
	(Dollars in thousands)
Income tax expense	$	33,628		$	28,427
Effective tax rate	24		%	24		%

The effective tax rate for the three months ended March 31, 2016 and 2015 was lower than the statutory federal rate of 35% primarily due to tax benefits from foreign income taxed at lower rates, partially offset by state income taxes.

Liquidity and Capital Resources

	March 31,		December 31,
	2016		2015
	(In thousands)
Cash and cash equivalents	$	234,025	$	228,659
Marketable securities	1,661,804		1,686,771
Total	$	1,895,829	$	1,915,430

As of March 31, 2016, our principal source of liquidity was $234.0 million of cash and cash equivalents and $1.7 billion of marketable securities. The marketable securities primarily consist of debt securities issued by the U.S. Treasury meeting the criteria of our investment policy, which is focused on the preservation of our capital through investment in investment grade securities. The cash equivalents consist of amounts invested in money market funds and U.S. Treasury bills purchased with original maturities of less than 90 days. As of March 31, 2016, all of our debt securities have contractual maturities of less than one year. Our cash and cash equivalents are readily accessible. For additional information on our investment portfolio, see Note 2, “Cash, Cash Equivalents, and Marketable Securities,” of our Notes to Condensed Consolidated Financial Statements in Part I, Item I of this Quarterly Report on Form 10-Q.

As of March 31, 2016, the amount of cash and cash equivalents and marketable securities held by foreign subsidiaries was $1.2 billion. Our intent remains to indefinitely reinvest these funds outside of the U.S. and accordingly, we have not provided deferred U.S. taxes for these funds. In the event funds from foreign operations are needed to fund operations in the U.S. and if U.S. tax has not already been provided, we would be required to accrue and pay additional U.S. taxes in order to repatriate these funds.

As of March 31, 2016, we had $500.0 million principal amount outstanding of the 5.25% senior unsecured notes due 2025 and $750.0 million principal amount outstanding of the 4.625% senior unsecured notes due 2023.

As of March 31, 2016, there were no borrowings outstanding under the $200.0 million unsecured revolving credit facility that will expire in 2020.

As of March 31, 2016, we had $1.25 billion principal amount outstanding of 3.25% subordinated convertible debentures due 2037. The price of our common stock exceeded the conversion price threshold trigger during the first quarter of 2016. Accordingly, the Subordinated Convertible Debentures are convertible at the option of each holder through June 30, 2016. We do not expect a material amount of the Subordinated Convertible Debentures to be converted in the near term as the trading price of the debentures exceeds the value that is likely to be received upon conversion. However, we cannot provide any assurance that the trading price of the debentures will continue to exceed the value that would be derived upon conversion or that the holders will not elect to convert the Subordinated Convertible Debentures. If a holder elects to convert its Subordinated Convertible Debentures, we are permitted under the Indenture to pursue an exchange in lieu of conversion or to settle the conversion value (as defined in the Indenture) in cash, stock, or a combination thereof. If we choose not to pursue or cannot complete an exchange in lieu of conversion, we currently have the intent and the ability (based on current facts and circumstances) to settle the principal amount of the Subordinated Convertible Debentures in cash. However, if the principal amount of the Subordinated Convertible Debentures that holders actually elect to convert exceeds our cash on hand and cash from operations, we will need to draw cash from existing financing or pursue additional sources of financing to settle the Subordinated Convertible Debentures in cash. We cannot provide any assurances that we will be able to obtain new sources of financing on terms acceptable to us or at all, nor can we assure that we will be able to obtain such financing in time to settle the Subordinated Convertible Debentures that holders elect to convert.

17

On February 15, 2016, we paid contingent interest of $6.5 million in addition to the normal coupon interest on our Subordinated Convertible Debentures. In February 2016, the upside trigger on the Subordinated Convertible Debentures was met for the six month interest period from February 15, 2016 through August 15, 2016. On August 15, 2016, we will pay contingent interest of $6.8 million in addition to the normal coupon interest to holders of record of the Subordinated Convertible Debentures as of August 1, 2016. The upside trigger is met if the Subordinated Convertible Debentures’ average trading price is at least 150% of par during the 10 trading days before each semi-annual interest period. The upside trigger is tested semi-annually for the following six months. The semi-annual upside contingent interest payment, for a given period, can be approximated by applying the annual rate of 0.5% to the aggregate market value of all outstanding Subordinated Convertible Debentures and dividing by two for that semi-annual period payment amount.

We derive significant tax savings from the Subordinated Convertible Debentures.  During the three months ended March 31, 2016 and 2015, the interest deduction, for income tax purposes, related to our Subordinated Convertible Debentures, excluding contingent interest, was $43.9 million and $41.2 million, respectively, compared to coupon interest expense of $10.2 million for each of the same periods. For income tax purposes, we deduct interest expense on the Subordinated Convertible Debentures calculated at 8.5% of the adjusted issue price, subject to adjustment for actual versus projected contingent interest. The adjusted issue price, and consequently the interest deduction for income tax purposes, grows over the term due to the difference between the interest deduction taken using a comparable yield of 8.5% on the adjusted issue price, and the coupon rate of 3.25% on the principal amount, compounded annually. The interest deduction taken is subject to recapture upon settlement to the extent that the amount paid (in cash or stock) to settle the Subordinated Convertible Debentures is less than the adjusted issue price. Interest recognized in accordance with GAAP, which is calculated at 8.39% of the liability component of the Subordinated Convertible Debentures, will also grow over the term, but at a slower rate. This difference will result in a continuing increase in the deferred tax liability on our Condensed Consolidated Balance Sheet.

We believe existing cash, cash equivalents and marketable securities, and funds generated from operations, together with our borrowing capacity under the unsecured revolving credit facility should be sufficient to meet our working capital, capital expenditure requirements, and to service our debt for at least the next 12 months. We regularly assess our cash management approach and activities in view of our current and potential future needs.

In summary, our cash flows for the three months ended March 31, 2016 and 2015 are as follows:

	Three Months Ended March 31,
	2016			2015
	(In thousands)
Net cash provided by operating activities	$	143,626		$	132,669
Net cash provided by investing activities	19,697			51,155
Net cash (used in) provided by financing activities	(158,258		)	330,263
Effect of exchange rate changes on cash and cash equivalents	301			184
Net increase in cash and cash equivalents	$	5,366		$	514,271

Cash flows from operating activities

Our largest source of operating cash flows is cash collections from our customers. Our primary uses of cash from operating activities are for personnel related expenditures, and other general operating expenses, as well as payments related to taxes, interest and facilities.

Net cash provided by operating activities increased during the three months ended March 31, 2016, primarily due to an increase in cash collected from customers, partially offset by an increase in cash paid to employees and vendors and cash paid for interest. Cash received from customers increased primarily due to an increase in the number of new and renewal domain name registrations during the three months ended March 31, 2016, and the increases in the .net domain name registration fees in February 2016. Payments to employees and vendors increased primarily due to a slight increase in general operating expenses and the timing of payments. Cash paid for interest increased due to higher contingent interest related to the Subordinated Convertible Debentures.

Cash flows from investing activities

The changes in cash flows from investing activities primarily relate to purchases, maturities and sales of marketable securities, and purchases of property and equipment.

The decrease in cash flows provided by investing activities was primarily due to lower proceeds from sales and maturities of marketable securities, net of purchases, during the first quarter of 2016, compared to the same period in 2015, partially offset by a decrease in purchases of property and equipment and other investing activities.

18

Cash flows from financing activities

The changes in cash flows from financing activities primarily relate to share repurchases, proceeds from and repayments of borrowings, our employee stock purchase plan, and excess tax benefits from stock-based compensation.

The change in cash (used in) provided by financing activities during the three months ended March 31, 2016 was primarily due to a decrease in proceeds from borrowings as we issued the senior notes in March 2015, partially offset by a decrease in share repurchases.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no significant changes in our market risk exposures since December 31, 2015.

ITEM 4.    CONTROLS AND PROCEDURES

Based on our management’s evaluation, with the participation of our Chief Executive Officer (our principal executive officer) and our Chief Financial Officer (our principal financial officer), as of March 31, 2016, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended March 31, 2016 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Inherent Limitations of Disclosure Controls and Internal Control over Financial Reporting

Because of their inherent limitations, our disclosure controls and procedures and our internal control over financial reporting may not prevent material errors or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to risks, including that the control may become inadequate because of changes in conditions or that the degree of compliance with our policies or procedures may deteriorate.

PART II—OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

Verisign is involved in various investigations, claims and lawsuits arising in the normal conduct of its business, none of which, in its opinion, will have a material adverse effect on its financial condition, results of operations, or cash flows. The Company cannot assure you that it will prevail in any litigation. Regardless of the outcome, any litigation may require the Company to incur significant litigation expense and may result in significant diversion of management attention.

ITEM 1A.RISK FACTORS

In addition to other information in this Form 10-Q, the following risk factors should be carefully considered in evaluating us and our business because these factors currently have a significant impact or may have a significant impact on our business, operating results or financial condition. Actual results could differ materially from those projected in the forward-looking statements contained in this Form 10-Q as a result of the risk factors discussed below and elsewhere in this Form 10-Q and in other filings we make with the SEC.

Risks arising from our agreements governing our Registry Services business could limit our ability to maintain or grow our business.

We are parties to (i) a Cooperative Agreement (as amended) with the DOC with respect to the .com gTLD and certain other aspects of the DNS and (ii)  Registry Agreements with ICANN for .com, .net, .name and other gTLDs including our IDN gTLDs. As substantially all of our revenues are derived from our Registry Services business, limitations in these agreements could have a material impact on our business.

Under the terms of the Cooperative Agreement with the DOC and the .com Registry Agreement with ICANN, we are generally restricted from increasing the price of registrations or renewals of .com domain names except that we are entitled to increase the price up to 7%, with the prior approval of the DOC, due to the imposition of any new Consensus Policies or documented extraordinary expense resulting from an attack or threat of attack on the security and stability of the DNS. However, it is uncertain that such circumstances will arise, or if they do, that the DOC will approve our request to increase the price for .com domain name registrations. We also have the right under the Cooperative Agreement to seek the removal of these pricing restrictions if we demonstrate that market conditions no longer warrant such restrictions. However, it is uncertain that such circumstances will arise, or if they do, that the DOC will agree to the removal of these pricing restrictions. In connection with a renewal of the .com Registry Agreement, we can seek an increase of the price for .com domain name registrations. Regardless of whether we seek such an increase, there can be no assurance of the price that DOC will approve in connection with a renewal of the .com Registry Agreement. Under the terms of the .net and .name Registry Agreements with ICANN, we are permitted to increase the price of registrations and renewals in these TLDs up to 10% per year. Additionally, ICANN’s registry agreements for the new gTLDs do not contain such pricing restrictions.

Vertical integration. Under the .com, .net and .name Registry Agreements with ICANN, as well as the Cooperative Agreement with the DOC, we are not permitted to acquire, directly or indirectly, control of, or a greater than 15% ownership interest in, any ICANN-accredited registrar. Historically, all gTLD registry operators were subject to this vertical integration prohibition; however, ICANN has established a process whereby registry operators may seek ICANN’s approval to remove this restriction, and ICANN has approved such removal in some instances. If we were to seek removal of the vertical integration restrictions contained in our agreements, it is uncertain whether ICANN and/or DOC approval would be obtained. Additionally, ICANN’s registry agreement for new gTLDs generally permits such vertical integration, with certain limitations including ICANN’s right, but not the obligation, to refer such vertical integration activities to competition authorities. Furthermore, unless prohibited by ICANN as noted above, such vertical integration restrictions do not generally apply to ccTLD registry operators. If registry operators of new or existing gTLDs, or ccTLDs, are able to obtain competitive advantages through such vertical integration, it could materially harm our business.

Termination or non-renewal. Under the Cooperative Agreement (as amended) the DOC must approve any renewal or extension of the .com Registry Agreement. The DOC, under certain circumstances, could refuse to grant its approval to the renewal of the .com Registry Agreement on similar terms, or at all. Any failure of the DOC to approve the renewal of the .com Registry Agreement prior to the expiration of its current term on November 30, 2018 would have a material adverse effect on our business. Under certain circumstances, ICANN could terminate or refuse to renew one or more of our Registry Agreements including those for .com, .net, and our other gTLDs. See the “Industry Regulation” section in Part I, Item 1 of  the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, which was filed on February 19, 2016, for further information on these circumstances.

21

Modification or amendment. Our Registry Agreements for new gTLDs, including the Registry Agreements for our IDN gTLDs, include ICANN’s right to amend the agreement without our consent, which could impose unfavorable contract obligations on us that could impact our plans and competitive positions with respect to new gTLDs. At the time of renewal of our .com or .net Registry Agreements, ICANN might also attempt to impose this same unilateral right to amend these registry agreements under certain conditions. ICANN has also included new mandatory obligations on new gTLD registry operators, including us, that may increase the risks and potential liabilities associated with operating new gTLDs. ICANN might seek to impose these new mandatory obligations in our other Registry Agreements under certain conditions.

Legal challenges. Our Registry Agreements have faced, and could continue to face, challenges, including possible legal challenges resulting from our activities or the activities of ICANN, registrars, registrants and others, and any adverse outcome from such challenges could have a material adverse effect on our business.

Consensus Policies. Our Registry Agreements with ICANN require us to implement Consensus Policies. ICANN could adopt Consensus Policies that are unfavorable to us as the registry operator of .com, .net and our othergTLDs, that are inconsistent with our current or future plans, that impose substantial costs on our business, or that affect our competitive position. Such Consensus Policies could have a material adverse effect on our business.

Governmental regulation and the application of new and existing laws in the U.S. and overseas may slow business growth, increase our costs of doing business, create potential liability and have an adverse effect on our business.

Application of new and existing laws and regulations in the U.S. or overseas to the Internet and communications industry can be unclear. The costs of complying or failing to comply with these laws and regulations could limit our ability to operate in our current markets, expose us to compliance costs and substantial liability and result in costly and time-consuming litigation. For example, the government of the People’s Republic of China (“PRC”) has indicated that it will issue new regulations, and begin to enforce existing regulations, that will require registry operators to, among other things, obtain a government-issued license in order to provide Registry Services to registrars located in the PRC.  The regulations could impose additional costs on our provision of Registry Services in the PRC and could impact the growth or renewal rates of domain name registrations in the PRC.  While we have submitted applications for .com and .net TLDs to the government of the PRC to obtain the licenses required by the regulations, there can be no assurance that we will obtain the licenses or obtain the licenses in a timely manner. Our failure to obtain the licenses or other delay in obtaining the licenses, including delays potentially imposed by ICANN, could result in restrictions, up to and including, a prohibition on the sale of our Registry Services to registrars located in the PRC. In addition to registry operators, the regulations will require registrars to obtain a government-issued license for each TLD whose domain name registrations they intend to sell directly to registrants. Their failure to obtain the required licenses could also impact the growth of our business in the PRC.

Foreign, federal or state laws could have an adverse impact on our business, financial condition, results of operations and cash flows, and our ability to conduct business in certain foreign countries. For example, laws designed to restrict who can register and who can distribute domain names, the online distribution of certain materials deemed harmful to children, online gambling, counterfeit goods, and cybersquatting; laws designed to require registrants to provide additional documentation or information in connection with domain name registrations; and laws designed to promote cyber security may impose significant additional costs on our business or subject us to additional liabilities. We have contracts pursuant to which we provide services to the U.S. government and they impose compliance costs, including compliance with the Federal Acquisition Regulation, which could be significant to the Company.

Due to the nature of the Internet, it is possible that state or foreign governments might attempt to regulate Internet transmissions or prosecute us for violations of their laws. We might unintentionally violate such laws, such laws may be modified and new laws may be enacted in the future. In addition, as we began to launch our IDN gTLDs in late 2015, we may raise our profile in certain foreign countries thereby increasing the regulatory and other scrutiny of our operations. Any such developments could increase the costs of regulatory compliance for us, affect our reputation, force us to change our business practices or otherwise materially harm our business. In addition, any such new laws could impede growth of or result in a decline in domain name registrations, as well as impact the demand for our services.

Undetected or unknown defects in our service, security breaches, and DDoS attacks could expose us to liability and harm our business and reputation.

Services as complex as those we offer or develop could contain undetected defects or errors. Despite testing, defects or errors may occur in our existing or new services, which could result in compromised customer data, diversion of development resources, injury to our reputation, tort or contract claims, increased insurance costs or increased service costs, any of which could harm our business. Performance of our services could have unforeseen or unknown adverse effects on the networks over which they are delivered as well as, more broadly, on Internet users and consumers, and third-party applications and services that utilize our services, which could result in legal claims against us, harming our business. Our failure to identify, remediate

22

and mitigate security breaches or our inability to meet customer expectations in a timely manner could also result in loss of or delay in revenues, loss of market share, failure to achieve market acceptance, injury to our reputation and increased costs.

In addition to undetected defects or errors, we are also subject to cyber-attacks and attempted security breaches. We retain certain customer and employee information in our data centers and various domain name registration systems. It is critical to our business strategy that our facilities and infrastructure remain secure and are perceived by the marketplace to be secure. The Company, as an operator of critical Internet infrastructure, is frequently targeted and experiences a high rate of attacks. These include the most sophisticated forms of attacks, such as advanced persistent threat (“APT”) attacks and zero-hour threats, which means that the threat is not compiled or has been previously unobserved within our observation and threat indicators space until the moment it is launched, and may well target specific unidentified or unresolved vulnerabilities that exist only within the target’s operating environment, making these attacks virtually impossible to anticipate and difficult to defend against. The Shared Registration System, the root zone servers, the Root Zone Management System, the TLD name servers and the TLD zone files that we operate are critical hardware and software to our Registry Services operations. Despite the significant time and money expended on our security measures, we have been subject to a security breach, as disclosed in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2011, and our infrastructure may in the future be vulnerable to physical break-ins, outages resulting from destructive malcode, computer viruses, attacks by hackers or nefarious actors or similar disruptive problems, including hacktivism. It is possible that we may have to expend additional financial and other resources to address such problems. Any physical or electronic break-in or other security breach or compromise of the information stored at our data centers or domain name registration systems may cause an outage of or jeopardize the security of information stored on our premises or in the computer systems and networks of our customers. In such an event, we could face significant liability, customers could be reluctant to use our services and we could be at risk for loss of various security and standards-based compliance certifications needed for certain of our businesses, all or any of which could adversely affect our reputation and harm our business. Such an occurrence could also result in adverse publicity and therefore adversely affect the market’s perception of the security of e-commerce and communications over the Internet as well as of the security or reliability of our services.

Additionally, our networks have been, and likely will continue to be, subject to DDoS attacks. While we have adopted mitigation techniques, procedures and strategies to defend against such attacks, there can be no assurance that we will be able to defend against every attack, especially as the attacks increase in size and sophistication. Any attack, even if only partially successful, could disrupt our networks, increase response time, negatively impact our ability to meet our contracted service level obligations, and generally hamper our ability to provide reliable service to our Registry Services customers and the broader Internet community. Further, we sell DDoS protection services to our Security Services customers. Although we increase our knowledge of and develop new techniques in the identification and mitigation of attacks through the protection of our Security Services customers, the DDoS protection services share some of the infrastructure used in our Registry Services business. Therefore the provision of such services might expose our critical Registry Services infrastructure to temporary degradations or outages caused by DDoS attacks against those customers, in addition to any directed specifically against us and our networks.

Changes to the present multi-stakeholder model of Internet governance could materially and adversely impact our business.

The Internet is governed under a multi-stakeholder model comprising civil society, the private sector including for-profit and not-for-profit organizations such as ICANN, governments including the U.S. government, academia, non-governmental organizations and international organizations. Changes to the present multi-stakeholder model of Internet governance could materially and adversely impact our business.

Role of ICANN. ICANN plays a central coordination role in the multi-stakeholder system. ICANN is mandated by the non-binding Affirmation of Commitments (“AOC”) between the DOC and ICANN to uphold a private sector-led multi-stakeholder approach to Internet governance for the public benefit. If ICANN fails to uphold or significantly redefines the multi-stakeholder model, it could harm our business and our relationship with ICANN. Additionally, the AOC could be terminated or replaced with a different agreement between ICANN and some other authority which may establish new or different procedures for Internet governance that may be unfavorable to us. Also, legal, regulatory or other challenges could be brought challenging the legal authority underlying the roles and actions of ICANN.

Role of foreign governments. Some governments and members of the multi-stakeholder community have questioned ICANN’s role with respect to Internet governance and, as a result, could seek a multilateral oversight body as a replacement. Additionally, the role of ICANN’s Governmental Advisory Committee, which is comprised of representatives of national governments, could change, giving governments more control of Internet governance. For example, the AOC has established several multi-party review panels and contemplates a greater involvement by foreign governments and governmental authorities in the oversight and review of ICANN. These periodic review panels may take positions that are unfavorable to us. Some governments and governmental authorities outside the U.S. have in the past disagreed, and may in the future disagree, with the actions, policies or programs of ICANN, the U.S. Government and us relating to the DNS.

23

Role of the U.S. Government. The U.S. Government through the NTIA coordinates the management of important aspects of the DNS including the IANA functions and the root zone. On March 14, 2014, NTIA announced its intent to transition its oversight of the IANA function to the global multi-stakeholder community. NTIA asked ICANN to convene global stakeholders to develop a proposal to transition the current role played by NTIA in the coordination of the DNS. The NTIA is also coordinating a related and parallel transition of related root zone management functions. These related root zone management functions involve our role as Root Zone Maintainer under the Cooperative Agreement. At NTIA’s request, we submitted a proposal with ICANN to NTIA as to how best to remove NTIA’s administrative role associated with root zone maintenance in a manner that maintains the security, stability and resiliency of the Internet’s domain name system. We have performed the Root Zone Maintainer function as a community service spanning three decades without compensation at the request of the DOC under the Cooperative Agreement. While it is uncertain how the transition of oversight of the IANA functions and related root zone management functions will affect our role as Root Zone Maintainer, it is anticipated that performance of the root zone maintainer function would be conducted by us under a new root zone maintenance agreement with ICANN once our root zone maintainer function obligations under the Cooperative Agreement are completed. Although our Root Zone Maintainer function is separate from our Registry Agreements, there can be no assurance that the transition of the IANA functions, the transition of the related root zone management functions, and associated transition processes will not negatively impact our business.

As a result of these and other risks, Internet governance may change in ways that could materially harm our Registry Services business. For example, after the transition, if we perform the root zone maintainer function under a new agreement, we may be subject to claims challenging the agreement and we may not have immunity from or sufficient indemnification for such claims. If another party is designated to perform the Root Zone Maintainer function, there could be new or increased risks in availability, integrity and publication of the root zone file, which is critical to the operation of the DNS and our operation of our TLDs, including .com. Additionally, it may become more difficult for us to introduce new services in our Registry Services business and we could also be subject to additional restrictions on how our business is conducted, or to fees or taxes applicable to this business, which may not be equally applicable to our competitors.

We operate two root zone servers and are contracted to perform the Root Zone Maintainer function. Under ICANN’s New gTLD program, we face increased risk from these operations.

We administer and operate two of the 13 root zone servers. Root zone servers are name servers that contain authoritative data for the very top of the DNS hierarchy. These servers have the software and DNS configuration data necessary to locate name servers that contain authoritative data for the TLDs. These root zone servers are critical to the functioning of the Internet. Under the Cooperative Agreement, we play a key operational role in support of the IANA function as the Root Zone Maintainer. In this role, we provision and publish the authoritative data for the root zone itself multiple times daily and distribute it to all root server operators.

Under its New gTLD Program, ICANN has recommended delegations into the root zone of a large number of new gTLDs. In view of our role as the Root Zone Maintainer, and as a root server operator, we face increased risks should ICANN’s delegation of these new gTLDs, which represent unprecedented changes to the root zone in volume and frequency, cause security and stability problems within the DNS and/or for parties who rely on the DNS. Such risks include potential instability of the DNS including potential fragmentation of the DNS should ICANN’s delegations create sufficient instability, and potential claims based on our role in the root zone provisioning and delegation process. These risks, alone or in the aggregate, have the potential to cause serious harm to our Registry Services business. Further, our business could also be harmed through security, stability and resiliency degradation if the delegation of new gTLDs into the root zone causes problems to certain components of the DNS ecosystem or other aspects of the global DNS, or other relying parties are negatively impacted as a result of domain name collisions or other new gTLD security issues, such as exposure or other leakage of private or sensitive information.

Additionally, DNSSEC enabled in the root zone and at other levels of the DNS requires new preventative maintenance functions and complex operational practices that did not exist prior to the introduction of DNSSEC. Any failure by Verisign or the IANA functions operator to comply with stated practices, such as those outlined in relevant DNSSEC Practice Statements, introduces risk to DNSSEC relying parties and other Internet users and consumers of the DNS, which could have a material adverse impact on our business.

The evolution of Internet practices and behaviors and the adoption of substitute technologies may impact the demand for domain names.

Domain names and the domain name system have been used by consumers to access or disseminate information, conduct ecommerce, and develop an online identity for many years. The introduction of new technologies such as social media, mobile devices, apps and the dominance of search engines has evolved and changed the Internet practices and behaviors of consumers and businesses alike. These changes can impact the demand for domain names by those who purchase domain names for both commercial and investment reasons. Factors such as the evolving practices and preferences of Internet users and how they navigate the Internet as well the motivation of domain name registrants and how they will monetize their investment in domain names can negatively impact our business.

24

Some domain name registrants use a domain name to access or disseminate information, conduct ecommerce, and develop an online identity. Currently, Internet users often navigate to a website either by directly typing its domain name into a web browser, the use of an app on their smart phone or mobile device, the use of a voice recognition technology such as Siri, Cortana, or Echo, or through the use of a search engine. If (i) web browser or Internet search technologies were to change significantly; (ii) Internet users’ preferences or practices shift away from recognizing and relying on web addresses for navigation through the use of new and existing technologies; (iii) Internet users were to significantly decrease the use of web browsers in favor of applications to locate and access content; or (iv) Internet users were to increasingly use third level domains or alternate identifiers, such as social networking and microblogging sites, in each case the demand for domain names registered by us could decrease. This may trigger current customers and parties in our target markets to reevaluate their need for registration or renewal of domain names.

Some domain name registrars and registrants seek to generate revenue through advertising on their websites; changes in the way these registrars and registrants are compensated (including changes in methodologies and metrics) by advertisers and advertisement placement networks, such as Google, Yahoo!, Baidu and Bing, have, and may continue to, adversely affect the market for those domain names favored by such registrars and registrants which has resulted in, and may continue to result in, a decrease in demand and/or the renewal rate for those domain names. For example, according to published reports, Google has in the past changed (and may change in the future) its search algorithm, which may decrease site traffic to certain websites and provide less pay-per-click compensation for certain types of websites. This has made such websites less profitable which has resulted in, and may continue to result in, fewer domain registrations and renewals. In addition, as a result of the general economic environment, spending on online advertising and marketing may not increase or may be reduced, which in turn, may result in a further decline in the demand for those domain names.

If any of the above factors negatively impact the renewal of domain names or the demand for new domain names, we may experience material adverse impacts on our business, operating results, financial condition and cash flows.

Many of our target markets are evolving, and if these markets fail to develop or if our products and services are not widely accepted in these markets, our business could be harmed.

We target many new, developing and emerging markets to grow our business. These markets are rapidly evolving, and may not grow. Even if these markets grow, our services may not be widely used or accepted. Accordingly, the demand for our services in these markets is very uncertain. The factors that may affect market acceptance or adoption of our services in these markets include the following:

• regional Internet infrastructure development, expansion, penetration and adoption;

• market acceptance and adoption of products and services based upon technologies other than those we use, which are substitutes for our products and services;

• public perception of the security of our technologies and of IP and other networks;

• the introduction and consumer acceptance of new generations of mobile devices, and in particular the use of alternative Internet navigation mechanisms other than web browsers;

• increasing cyber threats and the associated customer need and demand for our Security Services offerings;

• government regulations affecting Internet access and availability, domain name registrations or the provision of registry services, or e-commerce and telecommunications over the Internet;

• preference by markets for the use of their own country’s ccTLDs as a substitute or alternative to our TLDs; and

• increased acceptance and use of new gTLDs as substitutes for legacy gTLDs.

If the market for e-commerce and communications over IP and other networks does not grow or these services are not widely accepted in the market, our business could be materially harmed.

We may face operational and other risks from the introduction of new gTLDs by ICANN and our provision of back-end registry services.

Approximately 1,000 new gTLDs have already been delegated in this initial round of new gTLDs. ICANN plans on offering a second round of new gTLDs after the completion of the initial round, the timing of which is uncertain. As set forth in the Verisign Labs Technical Report #1130007 version 2.2: New gTLD Security and Stability Considerations released on March 28, 2013, and reiterated in our further publications since then, we continue to believe there are issues regarding the deployment of the new gTLDs that should have been addressed before any new gTLDs were delegated, and despite our and others’ efforts, some of these issues have not been addressed by ICANN sufficiently, if at all. For example, domain name collisions have been reported to ICANN, which have resulted in various network interruptions for enterprises as well as confusion and usability

25

issues that have led to phishing attacks. It is anticipated that as additional new gTLDs are delegated more domain name collisions and associated security issues will occur.

We have entered into agreements to provide back-end registry services to other registry operators and applicants for new gTLDs. We may face risks regarding ICANN requirements for mitigating name collisions in the new gTLDs which we operate or for which we provide back-end registry services. For example, the possibility exists that “controlled interruption” periods may disrupt network services or that privacy or secure communications may be impacted as a result of insufficient preparedness by ICANN and the community for the launch of new gTLDs.

Our agreements to provide back-end registry services directly to other applicants and indirectly through reseller relationships expose us to operational and other risks. For example, the increase in the number of gTLDs for which we provide registry services on a standalone basis or as a back-end service provider could further increase costs or increase the frequency or scope of targeted attacks from nefarious actors.

The business environment is highly competitive and, if we do not compete effectively, we may suffer lower demand for our products, price reductions, reduced gross margins and loss of market share.

The Internet and communications network services industries are characterized by rapid technological change and frequent new product and service announcements which require us continually to improve the performance, features and reliability of our services, particularly in response to competitive offerings or alternatives to our products and services. In order to remain competitive and retain our market position, we must continually improve our access to technology and software, support the latest transmission technologies, and adapt our products and services to changing market conditions and our customers’ and Internet users’ preferences and practices, or launch entirely new products and services such as new gTLDs in anticipation of, or in response to, market trends. We cannot assure that competing technologies developed by others or the emergence of new industry standards will not adversely affect our competitive position or render our services or technologies noncompetitive or obsolete. In addition, our markets are characterized by announcements of collaborative relationships involving our competitors. The existence or announcement of any such relationships could adversely affect our ability to attract and retain customers. As a result of the foregoing and other factors, we may not be able to compete effectively with current or future competitors, and competitive pressures that we face could materially harm our business.

We face competition in the domain name registry space from other gTLD and ccTLD registries that are competing for the business of entities and individuals that are seeking to obtain a domain name registration and/or establish a Web presence. We have applied for new gTLDs including certain IDN gTLDs; however, there is no guarantee that such new gTLDs will be any more successful than the new gTLDs obtained by our competitors. For example, some of the new gTLDs, including our new gTLDs, may face additional universal acceptance and usability challenges in that current desktop and mobile device software does not ubiquitously recognize these new gTLDs and may be slow to adopt standards or support these gTLDs, even if demand for such products is strong. This is particularly true for IDN gTLDs, but applies to conventional gTLDs as well. As a result of these challenges, it is possible that resolution of domain names within some of these new gTLDs may be blocked within certain state or organizational environments, challenging universal resolvability of these strings and their general acceptance and usability on the Internet.

See the “Competition” section in Part I, Item 1 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, which was filed on February 19, 2016, for further information.

We must establish and maintain strong relationships with registrars and their resellers to maintain their focus on marketing our products and services otherwise our Registry Service business could be harmed.

One registrar accounts for approximately 30% of our revenues. All of our domain name registrations occur through registrars. Registrars and their resellers utilize substantial marketing efforts to increase the demand and/or renewal rates for domain names. Consolidation in the registrar or reseller industry or changes in ownership, management, or strategy among individual registrars or resellers could result in significant changes to their business, operating model and cost structure. Such changes could include reduced marketing efforts or other operational changes that could adversely impact the demand and/or the renewal rates for domain names. With the introduction of new gTLDs, many of our registrars have chosen to, and may continue to choose to, focus their short or long-term marketing efforts on these new offerings and/or reduce the prominence or visibility of our products and services on their e-commerce platforms. Our registrars and resellers not only sell domain name registrations of other competing registries but also sell and support their own services for websites such as email, website hosting, as well as other services. To the extent that registrars and their resellers focus more on selling support services and less on the registration and renewal of our TLDs, our revenues could be adversely impacted. Our ability to successfully market our services to, and build and maintain strong relationships with, new and existing registrars or resellers is a factor upon which successful operation of our business is dependent. If we are unable to keep a significant portion of their marketing efforts focused on selling our TLDs as opposed to other competing TLDs or their own services, our business could be harmed.

26

If we encounter system interruptions or failures, we could be exposed to liability and our reputation and business could suffer.

We depend on the uninterrupted operation of our various systems, secure data centers and other computer and communication networks. Our systems and operations are vulnerable to damage or interruption from:

• power loss, transmission cable cuts and other telecommunications failures;

• damage or interruption caused by fire, earthquake, and other natural disasters;

• attacks, including hacktivism, by miscreants or other nefarious actors;

• computer viruses or software defects;

• physical or electronic break-ins, sabotage, intentional acts of vandalism, terrorist attacks and other events beyond our control;

• risks inherent in or arising from the terms and conditions of our agreements with service providers to operate our networks and data centers;

• state suppression of Internet operations; and

• any failure to implement effective and timely remedial actions in response to any damage or interruption.

Most of the computing infrastructure for our Shared Registration System is located at, and most of our customer information is stored in, our facilities in New Castle, Delaware; Dulles, Virginia; and Fribourg, Switzerland. To the extent we are unable to partially or completely switch over to our primary alternate or tertiary sites, any damage or failure that causes interruptions in any of these facilities or our other computer and communications systems could materially harm our business. Although we carry insurance for property damage, we do not carry insurance or financial reserves for such interruptions, or for potential losses arising from terrorism.

In addition, our Registry Services business and certain of our other services depend on the efficient operation of the Internet connections to and from customers to our Shared Registration System residing in our secure data centers. These connections depend upon the efficient operation of Internet service providers and Internet backbone service providers, all of which have had periodic operational problems or experienced outages in the past beyond our scope of control. In addition, if these service providers do not protect, maintain, improve, and reinvest in their networks or present inconsistent data regarding the DNS through their networks, our business could be harmed.

A failure in the operation or update of the root zone servers, the root zone file, the root zone management system, the TLD name servers, or the TLD zone files that we operate, or other network functions, could result in a DNS resolution or other service outage or degradation; the deletion of one or more TLDs from the Internet; the deletion of one or more second-level domain names from the Internet for a period of time; or a misdirection of a domain name to a different server. A failure in the operation or update of the supporting cryptographic and other operational infrastructure that we maintain could result in similar consequences. A failure in the operation of our Shared Registration System could result in the inability of one or more registrars to register or maintain domain names for a period of time. In the event that a registrar has not implemented back-up services in conformance with industry best practices, the failure could result in permanent loss of transactions at the registrar during that period. Any of these problems or outages could create potential liability, including liability arising from a  failure to meet our service level agreements in our Registry Agreements, and could decrease customer satisfaction, harming our business or resulting in adverse publicity that could adversely affect the market’s perception of the security of e-commerce and communications over the Internet as well as of the security or reliability of our services.

Our operating results may be adversely affected as a result of unfavorable market, economic, social and political conditions.

An unstable global economic, social and political environment, including hostilities and conflicts in various regions both inside and outside the U.S., natural disasters, currency fluctuations, and country specific operating regulations may have a negative impact on demand for our services, our business and our foreign operations. The economic, social and political environment has impacted or may negatively impact, among other things:

• our customers’ continued growth and development of their businesses and our customers’ ability to continue as going concerns or maintain their businesses, which could affect demand for our products and services;

• current and future demand for our services, including decreases as a result of reduced spending on information technology and communications by our customers;

• price competition for our products and services;

27

• the price of our common stock;

• our liquidity and our associated ability to execute on any share repurchase plans;

• our ability to service our debt, to obtain financing or assume new debt obligations; and

• our ability to obtain payment for outstanding debts owed to us by our customers or other parties with whom we do business.

In addition, to the extent that the economic, social and political environment impacts specific industry and geographic sectors in which many of our customers are concentrated, that may have a disproportionate negative impact on our business.

Our international operations subject our business to additional economic and political risks that could have an adverse impact on our revenues and business.

A significant portion of our revenues is derived from customers outside the U.S. Doing business in international markets has required and will continue to require significant management attention and resources. We may also need to tailor some of our services for a particular market and to enter into international distribution and operating relationships. We may fail to maintain our ability to conduct business, including potentially material business operations in some international locations, or we may not succeed in expanding our services into new international markets or expand our presence in existing markets. Failure to do so could materially harm our business. Moreover, local laws and customs in many countries differ significantly from those in the U.S. In many foreign countries, particularly in those with developing economies, it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. law or regulations applicable to us. There can be no assurance that our employees, contractors and agents will not take actions in violation of such policies, procedures, laws and/or regulations. Violations of laws, regulations or internal policies and procedures by our employees, contractors or agents could result in financial reporting problems, investigations, fines, penalties, or prohibition on the importation or exportation of our products and services and could have a material adverse effect on our business. In addition, we face risks inherent in doing business on an international basis, including, among others:

• competition with foreign companies or other domestic companies entering the foreign markets in which we operate, as well as foreign governments actively promoting ccTLDs, which we do not operate;

• legal uncertainty regarding liability, enforcing our contracts and compliance with foreign laws;

• tariffs and other trade barriers and restrictions;

• difficulties in staffing and managing foreign operations;

• currency fluctuations;

• potential problems associated with adapting our services to technical conditions existing in different countries;

• difficulty of verifying customer information, including complying with the customer verification requirements of certain countries;

• more stringent privacy policies in some foreign countries;

• additional vulnerability from terrorist groups targeting U.S. interests abroad;

• potentially conflicting or adverse tax consequences;

• reliance on third parties in foreign markets in which we only recently started doing business; and

• potential concerns of international customers and prospects regarding doing business with U.S. technology companies due to alleged U.S. government data collection policies.

We rely on our intellectual property rights to protect our proprietary assets, and any failure by us to protect or enforce, or any misappropriation of, our intellectual property could harm our business.

Our success depends in part on our internally developed technologies and related intellectual property. Despite our precautions, it may be possible for a third party to copy or otherwise obtain and use our intellectual property without authorization. Furthermore, the laws of foreign countries may not protect our proprietary rights in those countries to the same extent U.S. law protects these rights in the U.S. In addition, it is possible that others may independently develop substantially equivalent intellectual property. If we do not effectively protect our intellectual property, our business could suffer. Additionally, we have filed patent applications with respect to some of our technology in the U.S. Patent and Trademark Office and patent offices outside the U.S. Patents may not be awarded with respect to these applications and even if such patents are awarded, third parties may seek to oppose or otherwise challenge our patents, and such patents’ scope may differ significantly from what was requested in the patent applications and may not provide us with sufficient protection of our intellectual property. In the

28

future, we may have to resort to litigation to enforce and protect our intellectual property rights, to protect our trade secrets or to determine the validity and scope of the proprietary rights of others. This type of litigation is inherently unpredictable and, regardless of its outcome, could result in substantial costs and diversion of management attention and technical resources. Some of the software and protocols used in our business are based on standards set by standards setting organizations such as the Internet Engineering Task Force. To the extent any of our patents are considered “standards essential patents,” we may be required to license such patents to our competitors on reasonable and non-discriminatory terms.

We also license third-party technology that is used in our products and services to perform key functions. These third-party technology licenses may not continue to be available to us on commercially reasonable terms or at all. The loss of or our inability to obtain or maintain any of these technology licenses could hinder or increase the cost of our launching new products and services, entering into new markets and/or otherwise harm our business. Some of the software and protocols used in our Registry Services business are in the public domain or may otherwise become publicly available, which means that such software and protocols are equally available to our competitors.

We rely on the strength of our Verisign brand to help differentiate ourselves in the marketing of our products. Dilution of the strength of our brand could harm our business. We are at risk that we will be unable to fully register, build equity in, or enforce the Verisign logo in all markets where Verisign products and services are sold. In addition, U.S. and most other countries’ trademark laws currently do not permit the registration of TLDs such as .com and .net as trademarks. Accordingly, we may not be able to fully realize or maintain the value of these intellectual property assets.

We could become subject to claims of infringement of intellectual property of others, which could be costly to defend and could harm our business.

We cannot be certain that we do not and will not infringe the intellectual property rights of others. Claims relating to infringement of intellectual property of others or other similar claims have been made against us and could be made against us in the future. It is possible that we could become subject to additional claims for infringement of the intellectual property of third parties. The international use of our logo could present additional potential risks for third party claims of infringement. Any claims, with or without merit, could be time consuming, result in costly litigation and diversion of technical and management personnel attention, cause delays in our business activities generally, or require us to develop a non-infringing logo or technology or enter into royalty or licensing agreements. Royalty or licensing agreements, if required, may not be available on acceptable terms or at all. If a successful claim of infringement were made against us, we could be required to pay damages or have portions of our business enjoined. If we could not identify and adopt an alternative non-infringing logo, develop non-infringing technology or license the infringed or similar technology on a timely and cost-effective basis, our business could be harmed.

A third party could claim that the technology we license from other parties infringes a patent or other proprietary right. Litigation between the licensor and a third party or between us and a third party could lead to royalty obligations for which we are not indemnified or for which indemnification is insufficient, or we may not be able to obtain any additional license on commercially reasonable terms or at all.

In addition, legal standards relating to the validity, enforceability, and scope of protection of intellectual property rights in Internet-related businesses, including patents related to software and business methods, are uncertain and still evolving. Because of the growth of the Internet and Internet-related businesses, patent applications are continuously being filed in connection with Internet-related technology. There are a significant number of U.S. and foreign patents and patent applications in our areas of interest, and we believe that there has been, and is likely to continue to be, significant litigation in the industry regarding patent and other intellectual property rights.

We could become involved in claims, lawsuits or investigations that may result in adverse outcomes.

In addition to possible intellectual property litigation and infringement claims, we are, and may in the future, become involved in other claims, lawsuits and investigations, including with respect to the root zone maintainer agreement now under negotiation with ICANN. Such proceedings may initially be viewed as immaterial but could prove to be material. Litigation is inherently unpredictable, and excessive verdicts do occur. Adverse outcomes in lawsuits and investigations could result in significant monetary damages, including indemnification payments, or injunctive relief that could adversely affect our ability to conduct our business and may have a material adverse effect on our financial condition, results of operations and cash flows. Given the inherent uncertainties in litigation,  even when we are able to reasonably estimate the amount of possible loss or range of loss and therefore record an aggregate litigation accrual for probable and reasonably estimable loss contingencies, the accrual may change in the future due to new developments or changes in approach.  In addition, such investigations, claims and lawsuits could involve significant expense and diversion of management’s attention and resources from other matters.

29

We continue to explore new strategic initiatives, the pursuit of any of which may pose significant risks and could have a material adverse effect on our business, financial condition and results of operations.

We are exploring a variety of possible strategic initiatives which may include, among other things, the investment in, and the pursuit of, new revenue streams, services or products, changes to our offerings, initiatives to leverage our patent portfolio, our Security Services business, back-end registry services and IDN gTLDs. In addition, we have evaluated and are pursuing and will continue to evaluate and pursue acquisitions of TLDs that are currently in operation and those that have not yet been awarded as long as they support our growth strategy.

Any such strategic initiative may involve a number of risks, including: the diversion of our management’s attention from our existing business to develop the initiative, related operations and any requisite personnel; possible regulatory scrutiny or third-party claims; possible material adverse effects on our results of operations during and after the development process; our possible inability to achieve the intended objectives of the initiative; as well as damage to our reputation if we are unsuccessful in pursuing a strategic initiative. Such initiatives may result in a reduction of cash or increased costs. We may not be able to successfully or profitably develop, integrate, operate, maintain and manage any such initiative and the related operations or employees in a timely manner or at all. Furthermore, under our agreements with ICANN, we are subject to certain restrictions in the operation of .com, .net,.name and other TLDs, including required ICANN approval of new registry services for such TLDs. If any new initiative requires ICANN review or ICANN determines that such a review is required, we cannot predict whether this process will prevent us from implementing the initiative in a timely manner or at all. Any strategic initiative to leverage our patent portfolio will likely increase litigation risks from potential licensees and we may have to resort to litigation to enforce our intellectual property rights.

We depend on key employees to manage our business effectively, and we may face difficulty attracting and retaining qualified leaders.

We operate in a unique competitive and highly regulated environment and we depend on the knowledge, experience, and performance of our senior management team and other key employees in this regard and otherwise. We have experienced changes in our management team during the last few years. If we are unable to attract, integrate, retain and motivate these key individuals and additional highly skilled technical, sales and marketing, and other experienced employees, and implement succession plans for these personnel, our business may suffer. For example, our service products are highly technical and require individuals skilled and knowledgeable in unique platforms and software implementation.

Changes in, or interpretations of, tax rules and regulations or our tax positions may adversely affect our effective tax rates.

We are subject to income taxes in both the U.S. and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We are subject to audit by various tax authorities. In accordance with U.S. GAAP, we recognize income tax benefits, net of required valuation allowances and accrual for uncertain tax positions. For example, we claimed a worthless stock deduction on our 2013 federal income tax return and recorded a net income tax benefit of $380.1 million. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different than that which is reflected in historical income tax provisions and accruals. Should additional taxes be assessed as a result of an audit or litigation, an adverse effect on our results of operations, financial condition and cash flows in the period or periods for which that determination is made could result.

A significant portion of our foreign earnings for the current fiscal year was earned in low tax jurisdictions. Our effective tax rate could fluctuate significantly on a quarterly basis and could be adversely affected to the extent earnings are lower than anticipated in countries where we have lower statutory rates and higher than anticipated in countries where we have higher statutory rates.

Various legislative proposals that would reform U.S. corporate tax laws have been proposed by the Obama administration as well as members of Congress, including proposals that would significantly impact how U.S. multinational corporations are taxed on foreign earnings. We are unable to predict whether these or other proposals will be implemented. Although we cannot predict whether or in what form any proposed legislation may pass, if enacted, such legislation could have a material adverse impact on our tax expense or cash flow.

Our foreign earnings, which are indefinitely reinvested offshore, constitute a majority of our cash, cash equivalents and marketable securities, and there is a high cost associated with a change in our indefinite reinvestment assertion or a repatriation of those funds to the U.S.

A majority of our cash, cash equivalents and marketable securities are held by our foreign subsidiaries. Our foreign earnings are indefinitely reinvested offshore and are not available to be used in the U.S. for working capital needs, debt obligations, acquisitions, share repurchases, dividends or other general corporate purposes. In the event that funds from our

30

foreign operations are needed in the U.S. for any purpose, we would be required to accrue and pay additional U.S. taxes in order to repatriate those funds, which could be significant.  Further, if we are unable to indefinitely reinvest our foreign earnings our effective tax rate would increase. These could adversely impact our business valuation and stock price.

Our marketable securities portfolio could experience a decline in market value, which could materially and adversely affect our financial results.

As of March 31, 2016, we had $1.9 billion in cash, cash equivalents, marketable securities and restricted cash, of which $1.7 billion was invested in marketable securities. The marketable securities consist primarily of debt securities issued by the U.S. Treasury meeting the criteria of our investment policy, which is focused on the preservation of our capital through the investment in investment grade securities. We currently do not use derivative financial instruments to adjust our investment portfolio risk or income profile.

These investments, as well as any cash deposited in bank accounts, are subject to general credit, liquidity, market and interest rate risks, which may be exacerbated by unusual events, such as the U.S. debt ceiling crisis and the Eurozone crisis, which affected various sectors of the financial markets and led to global credit and liquidity issues. During the 2008 financial crisis, the volatility and disruption in the global credit market reached unprecedented levels. If the global credit market deteriorates again or other events negatively impact the market for U.S. Treasury securities, our investment portfolio may be impacted and we could determine that some of our investments have experienced an other-than-temporary decline in fair value, requiring an impairment charge which could adversely impact our results of operations and cash flows.

We are subject to the risks of owning real property.

We own the land and building in Reston, Virginia, which constitutes our headquarters facility. Ownership of this property, as well as our data centers in Dulles, Virginia and New Castle, Delaware, may subject us to risks, including:

• adverse changes in the value of the properties, due to interest rate changes, changes in the commercial property markets, or other factors;

• ongoing maintenance expenses and costs of improvements;

• the possible need for structural improvements in order to comply with environmental, health and safety, zoning, seismic, disability law, or other requirements;

• the possibility of environmental contamination or notices of violation from federal or state environmental agencies; and

• possible disputes with neighboring owners, tenants, service providers or others.

We have anti-takeover protections that may discourage, delay or prevent a change in control that could benefit our stockholders.

Our amended and restated Certificate of Incorporation and Bylaws contain provisions that could make it more difficult for a third party to acquire us without the consent of our Board of Directors (“Board”). These provisions include:

• our stockholders may take action only at a duly called meeting and not by written consent;

• special meetings of our stockholders may be called only by the chairman of the board of directors, the president, our Board, or the secretary (acting as a representative of the stockholders) whenever a stockholder or group of stockholders owning at least thirty-five percent (35%) in the aggregate of the capital stock issued, outstanding and entitled to vote, and who held that amount in a net long position continuously for at least one year, so request in writing;

• vacancies on our Board can be filled until the next annual meeting of stockholders by a majority of directors then in office; and

• our Board has the ability to designate the terms of and issue new series of preferred stock without stockholder approval.

In addition, Section 203 of the General Corporation Law of Delaware prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person which together with its affiliates owns or within the last three years has owned 15% or more of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless in the same transaction the interested stockholder acquired 85% ownership of our voting stock (excluding certain shares) or the business combination is approved in a prescribed manner. Section 203 therefore may impact the ability of an acquirer to complete an acquisition of us after a successful tender offer and accordingly could discourage, delay or prevent an acquirer from making an unsolicited offer without the approval of our Board.

31

We have a considerable number of common shares subject to future issuance.

As of March 31, 2016, we had one billion authorized common shares, of which 108.9 million shares were outstanding. In addition, of our authorized common shares, 12.8 million common shares were reserved for issuance pursuant to outstanding equity and employee stock purchase plans (“Equity Plans”), and 36.4 million shares were reserved for issuance upon conversion of our 3.25% Junior Subordinated Convertible Debentures due 2037 (“Subordinated Convertible Debentures”). As a result, we keep substantial amounts of our common stock available for issuance upon exercise or settlement of equity awards outstanding under our Equity Plans and/or the conversion of Subordinated Convertible Debentures into our common stock. Issuance of all or a large portion of such shares would be dilutive to existing security holders, could adversely affect the prevailing market price of our common stock and could impair our ability to raise additional capital through the sale of equity securities.

Our financial condition and results of operations could be adversely affected if we do not effectively manage our indebtedness.

We have a significant amount of outstanding debt, and we may incur additional indebtedness in the future. Our substantial indebtedness, including any future indebtedness, requires us to dedicate a significant portion of our cash flow from operations or to arrange alternative liquidity sources to make principal and interest payments, when due, or to repurchase or settle our debt, if triggered, by certain corporate events, certain events of default, or conversion. It could also limit our flexibility in planning for or reacting to changes in our business and our industry, or make required capital expenditures and investments in our business; make it difficult or more expensive to refinance our debt or obtain new debt; trigger an event of default; and increase our vulnerability to adverse changes in general economic and industry conditions. Some of our debt contains covenants which may limit our operating flexibility, including restrictions on share repurchases, dividends, prepayment or repurchase of debt, acquisitions, disposing of assets, if we do not continue to meet certain financial ratios. Any rating assigned to our debt securities could be lowered or withdrawn by a rating agency, which could make it more difficult or more expensive for us to obtain additional debt financing in the future. The settlement amount, contingent interest, and potential recapture of income tax deductions related to our Subordinated Convertible Debentures can be substantial, and can increase significantly based on changes in our stock price. The occurrence of any of the foregoing factors could have a material adverse effect on our business, cash flows, results of operations and financial condition.

VERISIGN, INC.

ARTICLE I

Stockholders

Section 1. Annual Meeting. An annual meeting of the stockholders of the corporation, for the election of the Directors to succeed those whose terms expire and for the transaction of such other business as may properly come before the meeting, shall be held at such place, on such date and at such time as the Board of Directors shall each year fix.

Section 2. Special Meetings. (a) Special meetings of the stockholders, for any purpose or purposes prescribed in the notice of the meeting, shall be held at such place, on such date, and at such time as determined by the Board of Directors and may be called only by (i) the Board of Directors pursuant to a resolution adopted by a majority of the total number of directors authorized by resolutions (whether or not there exist any vacancies in previously authorized directorships at the time any such resolution is presented to the Board of Directors for adoption), (ii) the Chairman of the Board of Directors, (iii) the President or (iv) the Secretary whenever a stockholder or group of stockholders owning at least thirty-five percent (35%) in the aggregate of the capital stock issued, outstanding and entitled to vote, and who held that amount in a net long position continuously for at least one year (the “Eligibility Criteria”), so request in writing. Business transacted at special meetings shall be confined to the purpose or purposes stated in the notice of the meeting.

In the case of clause (iv) of the immediately preceding sentence, each such written request must be signed by each stockholder making the request and delivered to the Secretary at the principal executive office of the corporation and shall set forth (a) a brief description of the business desired to be brought before the special meeting of the stockholders, including the complete text of any resolutions to be presented at the special meeting of the stockholders with respect to such business, and the reasons for conducting such business at the meeting; (b) the date of request; (c)(i) if any stockholder making the request is a registered holder of the corporation’s stock, the name, address and ownership information, as they appear on the corporation’s books, of each such stockholder and (ii) if any stockholder making the request is not a registered holder of the corporation’s stock, proof of satisfaction by each such stockholder of the Eligibility Criteria which shall be substantially similar to the proof specified by Rule 14a-8(b)(2)(i) or (ii) under the Exchange Act, in each case, including a written agreement to update and supplement such information upon the occurrence of any changes thereto; (d) a representation that each requesting stockholder intends to appear in person or by proxy at the special meeting of the stockholders to transact the business specified; and (e) a representation that each requesting stockholder intends to hold the shares of the corporation’s stock set forth in the written request through the date of the special meeting of the stockholders; provided that, if any such requesting stockholder (x) fails to satisfy the Eligibility Criteria or to follow one of the procedural requirements described in clauses (a) through (e) of this sentence (the “Procedural Requirements”), the corporation shall not be obligated to call a special meeting unless the remaining requesting stockholders continue to satisfy the Eligibility Criteria and the Procedural Requirements or (y) fails to hold the required number of shares through the date of the special meeting (a “Non Performing Holder”), the corporation may cancel the special meeting (if previously called but not yet held) unless the remaining requesting stockholders have not failed to hold such shares through such date and continue to satisfy the Eligibility Criteria; provided, further, that the corporation may disregard future requests to call special meetings from each Non Performing Holder for the following two calendar years. Following receipt by the Secretary of a written request of stockholders that complies with the requirements set forth in this Section 2 (a “Special Meeting Request”), the Secretary shall call a special meeting of the stockholders.

(b) Revocation of Special Meeting Request. A stockholder may revoke a Special Meeting Request at any time by written revocation. Following such revocation, the Board of Directors, in its discretion, may cancel the special meeting unless, in the case of a Special Meeting Request , any remaining requesting stockholders continue to satisfy the Eligibility Criteria and the Procedural Requirements. For purposes of this Section 2, written revocation shall mean delivering a notice of revocation to the Secretary.

(c) Limitations. The Secretary shall not call a special meeting in response to a Special Meeting Request if (i) an identical or substantially similar item (as determined by the Board of Directors, a “Similar Item”) is included or will be included in the corporation’s notice of meeting as an item of business to be brought before a meeting of stockholders that will be held not later than ninety (90) days after the delivery date of the Special Meeting Request (the “Delivery Date”); (ii) the Delivery Date is during the period commencing ninety (90) days prior to the date of the next annual meeting of stockholders and ending on the date of the next

annual meeting of stockholders; (iii) a Similar Item was presented at any meeting of stockholders held within one hundred and eighty (180) days prior to the Delivery Date; (iv) the Special Meeting Request relates to an item of business that is not a proper subject for stockholder action under applicable law; or (v) such Special Meeting Request was made in a manner that involved a violation of Regulation 14A under the Exchange Act or other applicable law. For purposes of this Section 2, the election of directors shall be deemed to be a Similar Item with respect to all items of business involving the election or removal of directors.

For the purposes of this Section 2, “net long position” shall be determined with respect to each stockholder requesting a special meeting and each beneficial owner who is directing a stockholder to act on such owner’s behalf (each stockholder and owner, a “requesting party”) in accordance with the definition thereof set forth in Rule 14e-4 under the Securities Exchange Act of 1934, as amended from time to time, provided that (x) for purposes of such definition, in determining such requesting party’s “short position,” the reference in Rule 14e-4 to “the date that a tender offer is first publicly announced or otherwise made known by the bidder to holders of the security to be acquired” shall be the record date fixed to determine the stockholders entitled to deliver a written request for a special meeting, and the reference to the “highest tender offer price or stated amount of the consideration offered for the subject security” shall refer to the closing sales price of the corporation’s capital stock on the NASDAQ (or such other securities exchange designated by the Board of Directors if the corporation’s capital stock is not listed for trading on the NASDAQ) on such record date (or, if such date is not a trading day, the next succeeding trading day) and (y) the net long position of such requesting party shall be reduced by the number of shares as to which the Board of Directors determines that such requesting party does not, or will not, have the right to vote or direct the vote at the special meeting or as to which the Board of Directors determines that such requesting party has entered into any derivative or other agreement, arrangement or understanding that hedges or transfers, in whole or in part, directly or indirectly, any of the economic consequences of ownership of such shares.

Section 3. Place of Meetings. All meetings of stockholders shall be held at the principal office of the corporation unless a different place is fixed by the person or persons calling the meeting and stated in the notice of the meeting.

Section 4. Notices of Meetings and Adjourned Meetings. A written notice of each annual or special meeting of the stockholders stating the place, date, and hour thereof, shall be given by the Secretary (or the person or persons calling the meeting), not less than 10 nor more than 60 days before the date of the meeting, to each stockholder entitled to vote thereat, by leaving such notice with him or her or at his or her residence or usual place of business, or by depositing it postage prepaid in the United States mail, directed to each stockholder at his or her address as it appears on the records of the corporation. Notices of all meetings of stockholders shall state the purpose or purposes for which the meeting is called. An affidavit of the Secretary, Assistant Secretary, or transfer agent of the corporation that the notice has been given shall, in the absence of fraud, be primary facie evidence of the facts stated therein. No notice need be given to any person with whom communication is unlawful or to any person who has waived such notice either (a) in writing (which writing need not specify the business to be transacted at, or the purpose of, the meeting) signed by such person before or after the time of the meeting or (b) by attending the meeting except for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. When a meeting is adjourned to another time and place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken except that, if the adjournment is for more than 30 days or if, after the adjournment, a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in the manner provided in this Section 4.

Section 5. Quorum. At any meeting of the stockholders, a quorum for the transaction of business shall consist of one or more individuals appearing in person or represented by proxy and owning or representing a majority of the shares of the corporation then outstanding and entitled to vote thereat, unless or except to the extent that the presence of a larger number may be required by law (including as required from time to time by the Delaware General Corporation Law or the Certificate of Incorporation of the corporation). Where a separate vote by a class or classes is required, a majority of the shares of such class or classes then outstanding and entitled to vote present in person or by proxy shall constitute a quorum entitled to take action with respect to that vote on that matter. If a quorum shall fail to attend any meeting, the chairman of the meeting or the holders of a majority of the shares of stock entitled to vote thereat who are present, in person or by proxy, may adjourn the meeting to another place, date, or time.

Section 6. Organization. Such person as the Board of Directors may have designated or, in the absence of such a person, the President of the corporation or, in his or her absence, such person as may be chosen by the holders of a majority of the shares entitled to vote thereat who are present, in person or by proxy, shall call to order any meeting of the stockholders and act as chairman of the meeting. In the absence of the Secretary of the corporation, the secretary of the meeting shall be such person as the chairman appoints.

Section 7. Conduct of Business. The chairman of any meeting of stockholders shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of discussion as seem to him or her in order.

Section 8. Voting. Unless otherwise provided in the Certificate of Incorporation and subject to the provisions of Section 6 of Article IV hereof, each stockholder shall have one vote for each share of stock entitled to vote held by him or her of record according to the records of the corporation. Persons holding stock in a fiduciary capacity shall be entitled to vote the shares so held. Persons

whose stock is pledged shall be entitled to vote unless the pledgor in a transfer on the books of the corporation has expressly empowered the pledgee to vote the pledged shares, in which case only the pledgee or his or her proxy shall be entitled to vote. If shares stand of record in the names of two or more persons or if two or more persons have the same fiduciary relationship respecting the shares then, unless the Secretary is given written notice to the contrary and is furnished with a copy of the instrument or order appointing them or creating the relationship wherein it is so provided to the contrary: (a) if only one votes, his or her act binds all; (b) if more than one vote, the act of the majority so voting binds all; and (c) if more than one vote and the vote is evenly split, the effect shall be as provided by law.

Section 9. Proxies. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or any group of persons to act for him or her by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period.

Section 10. Action at Meeting. When a quorum is present at any meeting, action of the stockholders on any matter properly brought before such meeting, other than the election of directors, shall require, and may be effected by, the affirmative vote of the holders of a majority in interest of the stock present or represented by proxy and entitled to vote on the subject matter, except where a different vote is expressly required by law, the Certificate of Incorporation or these By-laws, in which case such express provision shall govern and control. The election of directors shall be determined by a plurality of votes cast. If the Certificate of Incorporation so provides, no ballot shall be required for the election of directors unless requested be a stockholder present or represented at the meeting and entitled to vote in the election.

Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the corporation (or the transfer agent or registrar, as the case may be). Notwithstanding the adoption of such a resolution, every holder of stock represented by certificates and upon request every holder of uncertificated shares shall be entitled to have a certificate signed by, or in the name of, the corporation by the Chairman or Vice-Chairman of the Board of Directors or the President or a Vice President, and by the Chief Financial Officer (in his or her capacity as treasurer) or an Assistant Chief Financial Officer (in his or her capacity as assistant treasurer), or the Secretary or an Assistant Secretary, certifying the number of shares owned by him or her in the corporation.

If the corporation shall be authorized to issue more than one class of stock or more than one series of and class, the face or back of each certificate issued by the corporation to represent such class or series shall either (a) set forth in full or summarize the powers, designations, preferences and relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions thereof, or (b) contain a statement that the corporation will furnish a statement of the same without charge to each stockholder who so requests.

Section 4. Holders of Record.

of stockholders shall be at the close of business on the day next preceding the day on which notice is given or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held, and, for determining stockholders entitled to receive payment of and dividend or other distribution or allotment of rights or to exercise any rights of change, conversion or exchange of stock or for any other purpose, the record date shall be at the close of business on the day on which the Board of Directors adopts a resolution relating thereto. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

Any stockholder of record seeking to have the stockholders authorize or take corporate action by written consent shall, by written notice to the Secretary, request the Board of Directors to fix a record date. The Board of Directors shall promptly, but in all events within 10 days after the date on which such a request is received, adopt a resolution fixing the record date.

ARTICLE V

Miscellaneous Provisions

Section 1. Interested Directors and Officers. (a) No contract or transaction between the corporation and one or more of its Directors or officers, or between the corporation and any other corporation, partnership, association, or other organization in which one or more of its Directors or officers are Directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the Director or officer is present at or participates in the meeting of the Board or committee thereof which authorizes the contract or transaction, or solely because his or her or their votes are counted for such purpose, if:

(i) the material facts as to his or her relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative vote of a majority of the disinterested Directors, even though the number of disinterested Directors is less than a quorum; or

(ii) the material facts as to his or her relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the shareholders; or

(iii) the contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified, by the Board of Directors, a committee thereof, or the shareholders.

(b) Common or interested Directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction.

Section 2. Indemnification.

(a) Right to Indemnification. The corporation shall indemnify and hold harmless each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a "proceeding"), by reason of the fact that he or she is or was a Director or an officer of the corporation or is or was serving at the request of the corporation as a Director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (hereinafter an "indemnitee"), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, to the fullest extent authorized by law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the corporation to provide broader indemnification rights than such law permitted the corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith; provided, however, that, except as provided in Subsection (c) of this Section

with respect to proceedings to enforce rights to indemnification, the corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the corporation; and provided further that as to any matter disposed of by a compromise payment by such person, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless such compromise and indemnification therefor shall be appropriated:

(i) by a majority vote of a quorum consisting of disinterested Directors;

(ii) if such a quorum cannot be obtained, then by a majority vote of a committee of the Board of Directors consisting of all the disinterested Directors;

(iii) if there are not two or more disinterested Directors in office, then by a majority of the Directors then in office, provided they have obtained a written finding by special independent legal counsel appointed by a majority of the Directors to the effect that, based upon a reasonable investigation of the relevant facts as described in such opinion, the person to be indemnified appears to have acted in good faith in the reasonable belief that his or her action was in the best interests of the corporation (or, to the extent that such matter relates to service with respect to an employee benefit plan, in the best interests of the participants or beneficiaries of such employee benefit plan);

(iv) by the holders of a majority of the shares of stock entitled to vote for the election of Directors, which majority may include interested Directors and officers; or

(v) by a court of competent jurisdiction.

An "interested" Director or officer is one against whom in such capacity the proceeding in question or other proceeding on the same or similar grounds is then pending. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

(b) Right to Advancement of Expenses. The right to indemnification conferred in Subsection (a) of this Section shall include the right to be paid by the corporation the expenses incurred in defending any such proceeding in advance of its final disposition (hereinafter an "advancement of expenses"); provided, however, that, if the Delaware General Corporation Law requires, an advancement of expenses incurred by an indemnitee in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon delivery to the corporation of an undertaking (hereinafter an "undertaking"), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a "final adjudication") that such indemnitee is not entitled to be indemnified for such expenses under this Section or otherwise, which undertaking may be accepted without reference to the financial ability of such person to make repayment.

(c) Right of Indemnitee to Bring Suit. If a claim under Subsection (a) or (b) of this Section is not paid in full by the corporation within 60 days after a written claim has been received by the corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be 20 days, the indemnitee may at any time there after bring suit against the corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) any suit by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking the corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met any applicable standard for indemnification set forth in the Delaware General Corporation Law. Neither the failure of the corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the corporation (including its Board of Directors, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Section or otherwise shall be on the corporation.

(d) Non-exclusivity of Rights. The rights to indemnification and to the advancement of expenses conferred in this Section shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, certificate of incorporation, by-law, agreement, vote of disinterested Directors or otherwise. The corporation's indemnification under this Section 2 of any person who is or was a Director or officer of the corporation, or is or was serving, at the request of the corporation, as a Director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall be reduced by any amounts such person receives as indemnification (i) under any policy of insurance purchased and maintained on his or her behalf by the corporation, (ii) from such other corporation, partnership, joint venture, trust or other enterprise, or (iii) under any other applicable indemnification provision.

(e) Joint Representation. If both the corporation and any person to be indemnified are parties to an action, suit or proceeding (other than an action or suit by or in the right of the corporation to procure a judgment in its favor), counsel representing the corporation therein may also represent such indemnified person (unless such dual representation would involve such counsel in a conflict of interest in violation of applicable principles of professional ethics), and the corporation shall pay all fees and expenses of such counsel incurred during the period of dual representation other than those, if any, as would not have been incurred if counsel were representing only the corporation; and any allocation made in good faith by such counsel of fees and disbursements payable under this paragraph by the corporation versus fees and disbursements payable by any such indemnified person shall be final and binding upon the corporation and such indemnified person.

(f) Indemnification of Employees and Agents of the Corporation. Except to the extent that rights to indemnification and advancement of expenses of employees or agents of the corporation may be required by any statute, the Certificate of Incorporation, this Section or any other by-law, agreement, vote of disinterested Directors or otherwise, the corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification and to the advancement of expenses to any employee or agent of the corporation to the fullest extent of the provisions of this Section with respect to the indemnification and advancement of expenses of Directors and officers of the corporation.

(g) Insurance. The corporation may maintain insurance, at its expense, to protect itself and any Director, officer, employee or agent of the corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law (as currently in effect or hereafter amended), the corporation's Certificate of Incorporation or these By-laws.

(h) Nature of Indemnification Right; Modification of Repeal of Indemnification. Each person who is or becomes a Director or officer as described in subsection (a) of this Section 2 shall be deemed to have served or to have continued to serve in such capacity in reliance upon the indemnity provided for in this Section 2. All rights to indemnification (and the advancement of expenses) under this Section 2 shall be deemed to be provided by a contract between the corporation and the person who serves as a Director or officer of the corporation at any time while these By-laws and other relevant provisions of the Delaware General Corporation Law and other applicable law, if any, are in effect. Such rights shall continue as to an indemnitee who has ceased to be a Director, officer, employee or agent and shall inure to the benefit of the indemnitee's heirs, executors and administrators. Any modification or repeal of this Section 2 shall not adversely affect any right or protection existing under this Section 2 at the time of such modification or repeal.

Section 3. Stock in Other Corporations. Subject to any limitations that may be imposed by the Board of Directors, the President or any person or persons authorized by the Board of Directors may, in the name and on behalf of the corporation, (a) call meetings of the holders of stock or other securities of any corporation or other organization, stock or other securities of which are held by this corporation, (b) act, or appoint any other person or persons (with or without powers of substitution) to act in the name and on behalf of the corporation, or (c) express consent or dissent, as a holder of such securities, to corporate or other action by such other corporation or organization.

Section 4. Checks, Notes, Drafts and Other Instruments. Checks, notes drafts and other instruments for the payment of money drawn or endorsed in the name of the corporation may be signed by any officer or officers or person or persons authorized by the Board of Directors to sign the same. No officer or person shall sign any such instrument as aforesaid unless authorized by the Board of Directors to do so.

Section 5. Corporate Seal. The seal of the corporation shall be circular in form, bearing the name of the corporation, the word "Delaware", and the year of incorporation, and the same may be used by causing it or a facsimile thereof to be impressed or affixed or in any other manner reproduced.

Section 6. Books and Records. The books, accounts and records of the corporation, except as may be otherwise required by law, may be kept outside of the State of Delaware, at such place or places as the Board of Directors may from time to time appoint. Except as may otherwise be provided by law, the Board of Directors shall determine whether and to what extent the books, accounts, records and documents of the corporation, or any of them, shall be open to the inspection of the stockholders.

Section 7. Severability. If any term or provision of the By-laws, or the application thereof to any person or circumstances or period of time, shall to any extent be invalid or unenforceable, the remainder of the By-laws shall be valid and enforced to the fullest extent permitted by law.

Section 8. Interpretations. Words importing persons include firms, associations and corporations, all words importing the singular number include the plural number and vice versa, and all words importing the masculine gender include the feminine gender.

Section 9. Amendments. These By-laws may at any time and from time to time be amended or repealed by the stockholders or, if such power is conferred by the Certificate of Incorporation, by the Board of Directors, except that any By-law added or amended by the stockholders may be altered or repealed only by the stockholders if such By-law expressly so provides.

VERISIGN, INC.

2006 EQUITY INCENTIVE PLAN

PERFORMANCE-BASED RESTRICTED STOCK UNIT AGREEMENT

The Board of Directors of VeriSign, Inc. has approved a grant to you (the “Participant” named below) of Performance-Based Restricted Stock Units (“RSUs”) pursuant to the VeriSign, Inc. 2006 Equity Incentive Plan (the “Plan”), as described below. Capitalized terms not defined herein shall have the meaning ascribed to them in the Plan.

Participant:

Number of RSUs:

Date of Grant:

Performance Period:

1. Grant of Awards. The Company has granted to Participant [ ] RSUs, subject to the terms of this Agreement and the terms of the Plan. The number of RSUs awarded to Participant represents a target award for the Performance Period (the “Target Award”). The number of RSUs of Participant’s actual earned award (the “Actual Award”) will be calculated as the Target Award multiplied by the Performance Multiplier, as determined by the Compensation Committee (the “Committee”). Each RSU represents the right to receive one (1) Share of Common Stock as set forth herein.

2. Performance Multiplier. The Performance Multiplier shall be determined by reference to achievement of the performance goals for the Performance Period as set forth in Exhibit A – Performance Goals and Payout Scale for Performance Based RSUs. The Performance Multiplier may range from zero to a maximum of 200% of the Target Award. In the event the Committee determines that the Performance Multiplier equals zero, all RSUs will be forfeited automatically on such date and all the rights of Participant to such RSUs shall immediately terminate.

3. Vesting Schedule. Participant’s Actual Award will vest on the date as set forth in Exhibit A (the “Vesting Date”).

4 Settlement. Settlement of vested RSUs shall be made within 30 days following the Vesting Date (provided that if at the time of settlement Participant is a “specified employee” of the Company under Section 409A of the Internal Revenue Code (“Section 409A”), and settlement would be treated as a payment made on separation of service, then if required to avoid the taxes imposed by Section 409A settlement shall be delayed by six (6) months (or if earlier, until death), or such other period of time as is then required to avoid such taxes). Notwithstanding any provision to the contrary in this agreement, to the extent necessary to avoid the imposition of any taxes under Section 409A, no payment or distribution under this agreement that becomes payable by reason of a Participant’s termination of employment with the Company will be made to such Participant unless such Participant’s termination of employment constitutes a “separation from service” (as such term is defined in Section 409A). For purposes of this agreement, each amount to be paid or benefit to be provided shall be construed as a separate identified payment for purposes of Section 409A. Settlement of vested RSUs shall be in Shares; provided, that pursuant to Section 10, if Shares may not be withheld as a result of foreign tax law, then an appropriate number of RSUs may or may not be automatically settled in cash, depending upon the taxable jurisdiction. In addition, if determined by the Committee in its discretion at the time of payment, RSUs may also be settled in cash or some combination of cash and Shares. The Participant shall pay to the Company the aggregate par value of the Shares issued prior to their issuance (par value being $0.001 per Share) with such payment deemed to have been made for each Share, by Participant’s services from the Date of Grant to the Vesting Date. Participant agrees that, if necessary due to applicable law, Participant shall pay to the Company each affected Share’s par value by making appropriate payroll deductions from funds due the Participant. Notwithstanding the issuance of Shares in settlement of the RSUs or the delivery of

one or more stock certificates for such Shares, the Shares shall be subject to applicable restrictions on transfer or sale, if any, as may be set forth in the Participant’s written employment or service contract with the Company or pursuant to any policy adopted by the Company, now or hereafter existing, that imposes stock ownership requirements, stock retention requirements or stock sale restrictions on the Participant. To enforce any restrictions or requirements on the Participant’s Shares, the Committee may require the Participant to deposit all certificates, together with stock powers or other instruments of transfer approved by the Committee appropriately endorsed in blank, with the Company or an agent designated by the Company to hold in escrow until such restrictions or requirements have lapsed or terminated, and the Committee may cause a legend or legends referencing such restrictions or requirements to be placed on the certificates.

5. No Stockholder Rights. Unless and until such time as Shares are issued in settlement of vested RSUs, the Participant shall have no ownership of the Shares allocated to the RSUs and shall have no right to vote such Shares, subject to the terms, conditions and restrictions described in the Plan and herein.

6. Dividend Equivalents. Any dividends following the Date of Grant but before the Vesting Date paid in cash on Shares of the Company shall be credited to the Participant as additional RSUs as if the RSUs held by the Participant were outstanding Shares, as follows: such credit shall be made in whole and/or fractional RSUs and shall be based on the Fair Market Value of the Shares on the date of payment of such dividend. All such additional RSUs shall also be adjusted by the Performance Multiplier, shall vest on the Vesting Date and shall be settled in accordance with, and at the time of, settlement of the vested RSUs to which they are related.

7. No Transfer. The RSUs and any interest therein: (i) shall not be sold, assigned, transferred, pledged, hypothecated, or otherwise disposed of, and (ii) shall, if the Participant’s continuous employment with the Company or any of its affiliates shall terminate for any reason (except as otherwise provided in the Plan or Section 8 below), be forfeited to the Company forthwith, and all the rights of the Participant to such RSUs shall immediately terminate.

8. Termination.

(i)    In the event of a Participant’s Termination by the Company or by the Participant, all unvested RSUs shall (except as otherwise provided in the Plan or herein), be forfeited to the Company forthwith, and all the rights of the Participant to such RSUs shall immediately terminate.

(ii)    In the event of a Participant’s Termination due solely to death or Disability while any RSUs granted hereunder remain unvested, the RSUs that are unvested shall accelerate as follows: (a) if such Termination occurs during the Performance Period and before the conclusion of the Performance Period, then the RSUs will fully accelerate based on the target performance achievement; and (b) if such Termination occurs after the conclusion of the Performance Period but before the award for the Performance Period has been paid, then the RSUs will fully accelerate based upon the actual performance achievement.

(iii)    In case of any dispute as to whether Termination has occurred, the Committee shall have sole discretion to determine whether such Termination has occurred and the effective date of such Termination.

9. Acknowledgement. The Company and the Participant agree that the RSUs are granted under and governed by this Performance-Based Restricted Stock Unit Agreement and by the provisions of the Plan (incorporated herein by reference). The Participant: (i) acknowledges receipt of a copy of the Plan and the Plan prospectus, (ii) represents that the Participant has carefully read and is familiar with their provisions, and (iii) hereby accepts the RSUs subject to all of the terms and conditions set forth herein and those set forth in the Plan. In the event that upon the 30th day after the Date of Grant, the Participant has not refused the RSUs by notice to the Company pursuant to Section 15 hereof, the Participant shall be deemed to have accepted the RSUs subject to all of the terms and conditions set forth herein and those set forth in the Plan.

10. Tax Consequences. The Participant acknowledges that there may be adverse tax consequences upon settlement of the RSUs or disposition of the Shares, if any, received in connection therewith and that the Company recommends that Participant should consult a tax adviser prior to such settlement or disposition. In particular, Participant must make arrangements, satisfactory to the Company, for satisfaction of any applicable foreign, federal, state or local income tax withholding requirements or social security requirements related to the grant of the RSUs or Participant’s receipt of Shares in settlement thereof, including, in either case, any dividend paid in respect thereof. In the event settlement of the RSUs is made in Shares, the Company will satisfy the minimum statutory withholding tax obligation by withholding a certain number of Shares otherwise deliverable from the total number of Shares deliverable to the Participant upon settlement unless Shares may not be withheld as a result of foreign tax law (in which case an appropriate number of RSUs may or may not be automatically settled in cash, depending upon the taxable jurisdiction). In the event that any RSUs are settled in cash, or Shares may not be withheld as a result of foreign tax law, the Participant hereby authorizes the Company to withhold the required minimum amount from Participant’s other sources of compensation from the Company or any Parent or Subsidiary.

11. Compliance with Laws and Regulations. The issuance of Shares will be subject to and conditioned upon compliance by the Company and Participant with all applicable state and federal laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s Common Stock may be listed or quoted at the time of such issuance or transfer.

12. VeriSign Incentive Compensation Recovery Policy in the Case of Inaccurate Financial Statements. The Committee has adopted an incentive compensation recovery policy (the “Policy”) which applies to all Section 16 executive officers and such other officers as the Committee may designate. The Policy applies whenever there is an Inaccurate Financial Statement (as such term is defined in the Policy), and, as a result, a covered executive has received more incentive compensation than would have otherwise occurred. To the extent you are subject to the Policy, you agree that the Committee can seek recovery of any such overpayment received under this Agreement per the terms of the Policy.

13. Successors and Assigns. The Company may assign any of its rights under this Agreement. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement will be binding upon Participant and Participant’s heirs, executors, administrators, legal representatives, successors and assigns.

14. Governing Law; Severability. This Agreement shall be governed by and construed in accordance with the internal laws of the Commonwealth of Virginia as such laws are applied to agreements between Virginia residents entered into and to be performed entirely within Virginia, excluding that body of laws pertaining to conflict of laws. If any provision of this Agreement is determined by a court of law to be illegal or unenforceable, then such provision will be enforced to the maximum extent possible and the other provisions will remain fully effective and enforceable.

15. Notices. Any notice required to be given or delivered to the Company shall be in writing and addressed to the Corporate Secretary of the Company at its principal corporate offices. Any notice required to be given or delivered to Participant shall be in writing (including email) and addressed to Participant at the participant’s Company email address, the address of record or to such other address as Participant may designate in writing from time to time to the Company or may be posted on the Participant’s E*Trade VeriSign employee stock plan account at www.etrade.com. All notices shall be deemed effectively given upon personal delivery, (i) three (3) days after deposit in the United States mail by certified or registered mail (return receipt requested), (ii) one (1) business day after its deposit with any return receipt express courier (prepaid), (iii) one (1) business day after transmission by fax or telecopier, (iv) upon receipt if sent by the Company to the Participant’s email address at the Company, or (v) upon posting on the Participant’s E*Trade VeriSign employee stock plan account at www.etrade.com.

16. Further Instruments. The parties agree to execute such further instruments and to take such further action as may be reasonably necessary to carry out the purposes and intent of this Agreement.

17. Headings. The captions and headings of this Agreement are included for ease of reference only and are to be disregarded in interpreting or construing this Agreement.

18. Entire Agreement; Modification. The Plan and this Performance-Based Restricted Stock Unit Agreement for these RSUs constitute the entire agreement and understanding of the parties with respect to the subject matter herein and supersede all prior understandings and agreements, whether oral or written, between the parties hereto with respect to the specific subject matter hereof. This Performance-Based Restricted Stock Unit Agreement may be amended only by a written instrument executed by an authorized representative of the Company and effectively given to the Participant pursuant to the methods of delivery set forth in Section 15 above. Any such amendment shall be deemed effective thirty (30) calendar days after the date on which it is effectively given to the Participant as described in Section 15 above, provided the Participant does not provide the Company with a written notice within that thirty (30) day period rejecting the amendment.

Please sign your name in the space provided below on this Performance-Based Restricted Stock Unit Agreement and return an executed copy to: Stock Administration, VeriSign, Inc., 12061 Bluemont Way, Reston, VA 20190.

Basis of Presentation

Interim Financial Statements

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared by VeriSign, Inc. (“Verisign” or the “Company”) in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, do not include all information and notes normally provided in audited financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation have been included. The results of operations for any interim period are not necessarily indicative of, nor comparable to, the results of operations for any other interim period or for a full fiscal year. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes contained in Verisign’s fiscal 2015 Annual Report on Form 10-K (the “2015 Form 10-K”) filed with the SEC on February 19, 2016.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard will become effective for the Company on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The guidance introduces a lessee model that requires most leases to be reported on the balance sheet. This ASU will become effective for the Company on January 1, 2019 and requires the modified retrospective transition method. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment award transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. There are different transition methods for different aspects of the standard. The new standard will be effective for the Company on January 1, 2017 with early adoption permitted. The Company is evaluating the timing of adoption, transition methods and the effect that this ASU will have on its consolidated financial statements and related disclosures.

The fair value of the Company’s investments in money market funds approximates their face value. Such instruments are classified as Level 1 and are included in Cash and cash equivalents. The fair value of the debt securities consisting of U.S. Treasury bills is based on their quoted market prices and are classified as Level 1. Debt securities purchased with original maturities in excess of three months are included in Marketable securities. The fair value of the equity securities of public companies is based on quoted market prices and are classified as Level 1. Investments in equity securities of public companies are included in Marketable securities. The fair value of the Company’s foreign currency forward contracts is based on foreign currency rates quoted by banks or foreign currency dealers and other public data sources.

The Company utilizes a valuation model to estimate the fair value of the contingent interest derivative on the subordinated convertible debentures due 2037 (“the Subordinated Convertible Debentures”). The inputs to the model include stock price, bond price, risk free interest rates, volatility, and credit spread observations. As several significant inputs are not observable, the overall fair value measurement of the derivative is classified as Level 3. The volatility and credit spread assumptions used in the calculation are the most significant unobservable inputs. As of March 31, 2016, the valuation of the contingent interest derivative assumed a volatility rate of approximately 27% and a credit spread of approximately 6%. The fair value of the contingent interest derivative would not have significantly changed using a volatility rate of either 22% or 32%, or a credit spread of either 5% or 7%.

The following table summarizes the change in the fair value of the Company’s contingent interest derivative on the Subordinated Convertible Debentures during the three months ended March 31, 2016 and 2015:

	Three Months Ended March 31,
	2016			2015

Beginning balance	$	30,126		$	26,755

Unrealized (gain) loss	(1,065		)	7,019
Ending balance	$	22,517		$	28,549

On February 15, 2016, the Company paid contingent interest of $6.5 million in addition to the normal coupon interest to holders of record of the Subordinated Convertible Debentures as of February 1, 2016. In February 2016, the upside trigger on the Subordinated Convertible Debentures was met for the six month interest period from February 15, 2016 through August 15, 2016. The $6.8 million contingent interest payable in August 2016 is included in the balance of the contingent interest derivative on the Subordinated Convertible Debentures as of March 31, 2016.

The Company’s other financial instruments include cash, accounts receivable, restricted cash, and accounts payable. As of March 31, 2016, the carrying value of these financial instruments approximated their fair value. The fair value of the Company’s Subordinated Convertible Debentures was $3.2 billion as of March 31, 2016. The fair values of the senior notes due 2023 (the “2023 Senior Notes”) and the senior notes due 2025 (the “2025 Senior Notes”) were $759.4 million and $505.6 million, respectively, as of March 31, 2016. The fair values of these debt instruments are based on available market information from public data sources and are classified as Level 2.
