Notes to Condensed Consolidated Financial Statements

(All amounts are in thousands, except per share data)

(Unaudited)

Unless otherwise noted, references in this Quarterly Report on Form 10-Q to VASCO, company, we, our, and
us, refer to VASCO Data Security International, Inc. and its subsidiaries.

Note 1  Summary of Significant Accounting Policies

Nature of Operations

VASCO Data Security International, Inc. and its wholly owned subsidiaries design, develop, market and support hardware and software security systems
that manage and secure access to information assets. VASCO has operations in Austria, Australia, Bahrain, Belgium, Brazil, China, France, India, Japan, The Netherlands, Switzerland, Singapore, the U.K., and the United States (U.S.).

Basis of Presentation

The accompanying
unaudited condensed consolidated financial statements include the accounts of VASCO Data Security International, Inc. and its subsidiaries and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission
regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for complete financial statements and should be read in conjunction with the audited
consolidated financial statements included in the companys Annual Report on Form 10-K for the year ended December 31, 2010.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the
audited consolidated financial statements, and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the results of the interim periods presented. All significant intercompany accounts and
transactions have been eliminated. The operating results for the interim periods presented are not necessarily indicative of the results expected for a full year.

Principles of Consolidation

The consolidated financial statements include the accounts of
VASCO Data Security International, Inc. and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

Estimates and Assumptions

The preparation
of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Foreign Currency Translation and Transactions

The financial position and results of the operations of the majority of the companys foreign subsidiaries are measured using the local
currency as the functional currency. Accordingly, assets and liabilities are translated into U.S. Dollars using current exchange rates as of the balance sheet date. Translation adjustments arising from differences in exchange rates are charged or
credited to other comprehensive income. Revenue and expenses are translated at average exchange rates prevailing during the year. Gains and losses resulting from foreign currency transactions are included in the consolidated statements of operations
in other income (expense).

The financial position and results of operations of our operations in Singapore and Switzerland are measured
in U.S. Dollars. For these subsidiaries, gains and losses that result from foreign currency transactions are included in the consolidated statements of operations in other income (expense).

For the three and six months ended June 30, 2011, gains resulting from foreign currency transactions were $30 and $58, respectively, compared
to losses of $118 and $267, for the same periods in 2010.

Revenue Recognition

We recognize revenue in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 985-605, Software
 Revenue Recognition, ASC 985-605-25, Revenue Recognition  Multiple Element Arrangementsand Staff Accounting Bulletin 104. Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has
occurred, the fee is fixed or determinable and collection of the revenue is probable.

Effective January 1, 2011, we adopted
Accounting Standards Update (ASU) 2009-13, Multiple-Deliverable Revenue Arrangements- a consensus of the FASB Emerging Issues Task Force,which amended ASC 985-605-25, and ASU 2009-14, Certain Revenue Arrangements That Include Software
Elements, which amended ASC 985-605. In multiple-element arrangements, the adoption of these two ASUs will result in some of our products continuing to be accounted for under the software provisions of ASC 985-605 and others to be accounted for
under the provisions that relate to the sale of non-software products.

In our typical multiple-element arrangement, the primary
deliverables include:



| | 1. | a client component (i.e., an item that is used by the person being authenticated in the form of either a new standalone hardware device or software that is downloaded onto a
device the customer already owns),
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | host system software that is installed on the customers systems (i.e., software on the host system that verifies the identity of the person being authenticated) or licenses
for additional users on the host system software if the host system software had been installed previously, and
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | post contract services (PCS) in the form of maintenance on the host system software or support.
| | -- | -----------------------------------------------------------------------------------------------

Our multiple-element arrangements may also include other items that are usually delivered prior to the recognition of any revenue and incidental to
the overall transaction such as initialization of the hardware device, customization of the hardware device itself or the packaging in which it is delivered, deployment services where we deliver the device to our customers end-use customer or
employee and, in some limited cases, professional services to assist with the initial implementation of a new customer.

Effective January 1, 2011 with the adoption of ASU 2009-13 and 14 there was no change in the
units of accounting, but there was a change in the method we use to allocate the revenue among the elements included in the arrangement.

In multiple-element arrangements that include a hardware client device, we allocate the selling price among the elements based on the percentage of
the estimated selling price of that element to the total of the estimated selling price of all of the elements. Any discount provided on the transaction as a whole is allocated among each of the elements included in the arrangement and any PCS
included in the transaction is deferred and amortized.

In multiple-element arrangements that include a software client device, we
continue to account for each element under the current standards of ASC 985-605 related to software. When software client device and host software are delivered elements, we use the Residual Method (ASC 605-25) for determining the amount of revenue
to recognize for token and software licenses if we have vendor specific objective evidence (VSOE) for all of the undelivered elements. Any discount provided to the customer is applied fully to the delivered elements in such an arrangement. We defer
the revenue for tokens and software in any multiple element arrangement where we do not have VSOE for any undelivered element. VSOE of fair value of PCS agreements is based on separate sales transactions on a worldwide basis. In sales arrangements
where VSOE of fair value has not been established, revenue for all elements is deferred and amortized over the life of the arrangement.

We do not expect a significant change in the pattern or timing of revenue recognition. The adoption of the new ASU 2009-13 and 14 did not have a
significant impact on the recognition of revenue for the three and six months ended June 30, 2011 and is not expected to have a material impact on the recognition of future revenues.

For transactions other than multiple-element arrangements, we recognize revenue as follows:



| | 1. | Hardware Revenue and License Fees: Revenue from the sale of computer security hardware or the license of software is recorded upon shipment or, if an acceptance period is
allowed, at the latter of shipment or customer acceptance. No significant obligations or contingencies exist with regard to delivery, customer acceptance or rights of return at the time revenue is recognized.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Maintenance and Support Agreements:Maintenance and support agreements generally call for us to provide software updates and technical support, respectively, to customers.
Revenue on maintenance and technical support is deferred and recognized ratably over the term of the applicable maintenance and support agreement.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | Services:Subscription revenue is recognized ratably over the period in which the service is provided.
| | -- | -----------------------------------------------------------------------------------------------------



| | 4. | Consulting and Education Services:We provide consulting and education services to our customers. Revenue from such services is recognized during the period in which the
services are performed.

##### Table of Contents

We recognize revenue from sales to distributors and resellers on the same basis as sales made directly
to customers. We recognize revenue when there is persuasive evidence that an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection of the revenue is probable.

For large-volume transactions, we may negotiate a specific price that is based on the number of users of the software license or quantities of
hardware supplied. The per unit prices for large-volume transactions are generally lower than transactions for smaller quantities and the price differences are commonly referred to as volume-purchase discounts.

All revenue is reported on a net basis, excluding any sales taxes or value added taxes.

Cash and Cash Equivalents

Cash and cash equivalents are stated at cost plus accrued interest,
which approximates fair value. Cash equivalents are high-quality short term money market instruments, with original maturities of three months or less. Cash and cash equivalents are held by a number of U.S. and non-U.S. commercial banks and money
market investment funds. Cash and cash equivalents at June 30, 2011 include $84,551 in money market investment funds or demand bank deposits for which fair value is equal to cost. These investments are valued using level one inputs, as defined
in ASC 820, Fair Value Measurements and Disclosures. Cash and cash equivalents also include $79 in bank certificates of deposit for which fair value was $79 at June 30, 2011. Bank certificates of deposit are valued using level two
inputs, as defined by ASC 820.

Accounts Receivable and Allowance for Doubtful Accounts

The credit-worthiness of customers (including distributors and resellers) is reviewed prior to shipment. A reasonable assurance of collection is a
requirement for revenue recognition. Verification of credit and/or the establishment of credit limits are part of the customer contract administration process. Credit limit adjustments for existing customers may result from the periodic review of
outstanding accounts receivable. The company records trade accounts receivable at invoice values, which are generally equal to fair value.

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make payments for goods and services. We analyze accounts receivable balances, customer
credit-worthiness, current economic trends and changes in our customer payment timing when evaluating the adequacy of the allowance for doubtful accounts. The allowance is based on a specific review of all significant past-due accounts. If the
financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required.

Inventories

Inventories, consisting
principally of hardware and component parts, are stated at the lower of cost or market. Cost is determined using the first-in-first-out (FIFO) method. We write down inventory when it appears that the carrying cost of the inventory may not be
recovered through subsequent sale of the inventory. The company analyzes the quantity of inventory on hand, the quantity sold in the past year, the anticipated sales volume in the form of sales to new customers as well as sales to previous
customers, the expected sales price and the cost of making the sale when evaluating the valuation of our inventory. If the sales volume or sales price of a specific model declines significantly, additional write downs may be required.

Property and Equipment

Property and
equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets ranging from three to seven years. Additions and improvements are capitalized, while expenditures for
maintenance and repairs are

##### Table of Contents

charged to operations as incurred. Gains or losses resulting from sales, disposals, or retirements are recorded as incurred, at which time related costs and accumulated depreciation are removed
from the accounts.

Research and Development Costs

Costs for research and development, principally the design and development of hardware, and the design and development of software prior to the determination of technological feasibility, are expensed as incurred
on a project-by-project basis.

Software Development Costs

We capitalize software development costs in accordance with ASC 985-20. Research costs and software development costs, prior to the establishment of technological feasibility, determined based upon the creation of
a working model, are expensed as incurred. Our software capitalization policy defines technological feasibility as a functioning beta test prototype with confirmed manufacturability (a working model), within a reasonably predictable range of costs.
Additional criteria include receptive customers, or potential customers, as evidenced by interest expressed in a beta test prototype, at some suggested selling price. Our policy is to amortize capitalized costs by the greater of (a) the ratio
that current gross revenue for a product bear to the total of current and anticipated future gross revenue for that product or (b) the straight-line method over the remaining estimated economic life of the product, generally two to five years,
including the period being reported on. No software development costs were capitalized during the six months ended June 30, 2011.

Income Taxes

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future
tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. We measure deferred tax assets and
liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We recognize the effect of a change in tax rates on deferred tax assets and
liabilities and in income in the period that includes the enactment date.

We monitor our potential income tax exposures as required by
ASC 740-10.

We have significant net operating loss carryforwards in the U.S. and other countries which are available to reduce the
liability on future taxable income. A valuation reserve has been provided for the U.S. and certain foreign operating loss carryforwards to offset most of these future benefits because we have not determined that their realization is more likely than
not.

Fair Value of Financial Instruments

At June 30, 2011 and December 31, 2010, our financial instruments were cash equivalents, accounts receivable, accounts payable and accrued liabilities. The estimated fair value of our financial
instruments has been determined by using available market information and appropriate valuation methodologies as described in Cash and Cash Equivalents above. The fair values of the financial instruments were not materially different from their
carrying amounts at June 30, 2011 and December 31, 2010.

Accounting for Leases

All of our leases are operating leases. Rent expense on facility leases is charged evenly over the life of the lease, regardless of the timing of
actual payments.

Goodwill and Other Intangibles

We account for goodwill and indefinite-lived intangible assets in accordance with ASC 350-20. Indefinite-lived intangible assets include customer lists, proprietary technology and other intangible assets.
Intangible assets other than patents with definite lives are amortized over the useful life, generally three to seven years for proprietary technology. Patents are amortized over the life of the patent, generally 20 years in the U.S.

We assess the impairment of goodwill and intangible assets with indefinite lives each year-end or whenever events or changes in circumstances
indicate that the carrying value may not be recoverable. Factors considered important which could trigger an impairment review include significant underperformance relative to expected historical or projected future operating results, significant
changes in the manner of our use of the acquired assets or the strategy for our overall business, and significant negative industry or economic trends. Once identified, the amount of the impairment is computed by comparing carrying value of the
assets to fair value. Fair value for goodwill is determined using our stock price which is a level 1 valuation, as defined in ASC 820-10. Fair value for trademarks is based on discounted estimated future cash flows, which is a level 3 valuation.

We have not recognized any impairment for the three and six months ended June 30, 2011 as the fair value of our reporting unit
substantially exceeded our carrying value at December 31, 2010 and there were no events or changes in circumstances during the three and six months ended June 30, 2011 that indicate that the carrying value may not be recoverable.

Warranty

Warranties are
provided on the sale of certain of our products and an accrual for estimated future claims is recorded at the time revenue is recognized. We estimate the cost based on past claims experience, sales history and other considerations. We regularly
assess the adequacy of our estimates and adjust the amounts as necessary. Our standard practice is to provide a warranty on our hardware products for either a one or two year period after the date of purchase. Customers may purchase extended
warranties covering periods from one to four years after the standard warranty period. We defer the revenue associated with the extended warranty and recognize it into income on a straight-line basis over the extended warranty period. We have
historically experienced minimal actual claims over the warranty period.

Note 2  Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable represents the balance due on credit sales made to customers. The allowance for doubtful accounts is an
estimate of losses that may result from customers inability to make payment on their outstanding balances.

Alfa & Ariss as further described in Notes 4 and 5. Other intangible assets include non-compete agreements, exclusive product endorsement, and customer relationships. Certain intangibles are denominated in local currencies and are subject

Note 8  Income Taxes

Our effective tax rate for the six months ended June 30, 2011 is equal to our expected annual tax rate of 30%. This is lower
than the U.S. statutory rate of 35%, primarily due to income in foreign jurisdictions taxed at lower rates, partially offset by losses in the U.S., where the tax benefit for these losses is fully reserved. In the first quarter of 2011, our effective
annual tax rate was estimated to be 28%. The tax rate of 32% for the second quarter reflects the increase in the expected annual rate.

Our effective tax rate for the six months ended June 30, 2010 was 25%. This was lower than the expected annual tax rate of 35%, due to
discrete items of $256 related to the true-up of our provisions for prior year tax returns as filed and other tax adjustments. The expected annual rate was equal to the U.S. statutory rate primarily due to income in foreign jurisdictions taxed at
lower rates, offset by losses in the U.S., where the tax benefit for these losses is fully reserved. In the first quarter of 2010, our effective annual tax rate was estimated to be 33%. The tax rate of 22% for the second quarter reflects discrete
items of $256, partially offset by the increase in the expected annual rate.

At December 31, 2010, we had U.S. net operating loss
(NOL) carryforwards of $21,247. Of this amount, $14,727 would result in a benefit to earnings. The remainder represents tax deductions for employee stock option gains, the benefit for which would be credited to paid-in capital. The U.S. loss
carryforwards expire in varying amounts beginning in 2020 and continuing through 2029. In addition, if certain substantial changes in the companys ownership were deemed to have occurred, there would be an annual limitation on the amount of the
U.S. carryforwards that could be utilized. At December 31, 2010, we also had foreign NOL carryforwards of $4,834. The foreign NOL carryforwards have no expiration dates. A valuation reserve has been provided for the U.S. and certain foreign
operating loss carryforwards to offset the future benefits because we have not determined that their realization is more likely than not.

Note 9  Warranties

We maintain a reserve for potential warranty claims related to products sold and recognized in revenue. We regularly reassess the
adequacy of our estimates and adjust the amounts as necessary. Our warranty reserve is included in other accrued expenses.

At June 30, 2011, deferred revenue from extended warranties was $86.

Note 10  Long-Term Compensation Plan and Stock Based Compensation

In the first quarter of 2011, we awarded 190 shares of restricted stock under the VASCO Data Security International, Inc. 2009
Equity Incentive Plan (2009 Equity Incentive Plan) consisting of 88 unissued shares subject to future performance criteria and 102 issued shares. The market value of the restricted shares was $1,588 at the date of grant and will be amortized over
the respective vesting periods of one to four years.

In the second quarter of 2011, we awarded 445 shares of restricted stock under the
2009 Equity Incentive Plan consisting of 149 unissued shares subject to future performance criteria and 296 issued shares. The market value of the restricted shares was $3,684 at the date of grant and will be amortized over the respective vesting
periods of three or four years.

Note 11  Common Stock and Earnings per Share

In connection with the 2009 Equity Incentive Plan described above, we issued 102 shares of restricted common stock during the
three months ended March 31, 2011 and 296 shares during the three months ended June 30, 2011.

Basic earnings per share is
based on the weighted average number of shares outstanding and excludes the dilutive effect of unexercised common stock equivalents. Diluted earnings per share is based on the weighted average number of shares outstanding and includes the dilutive
effect of unexercised common stock equivalents to the extent they are not anti-dilutive. The details of the earnings per share calculations for the three and six month periods ended June 30, 2011 and 2010 follow:

Cautionary Note
Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q, including Managements Discussion and Analysis of
Financial Condition and Results of Operations and Quantitative and Qualitative Disclosures About Market Risk contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 and Section 27A of
the Securities Act of 1933 concerning, among other things, the prospects of, and developments and business strategies for, VASCO and our operations, including the development and marketing of certain new products and the anticipated future growth in
certain markets in which we currently market and sell our products or anticipate selling and marketing our products in the future. These forward-looking statements (1) are identified by use of terms and phrases such as expect,
believe, will, anticipate, emerging, intend, plan, could, may, estimate, should, objective, goal,
possible, potential and similar words and expressions, but such words and phrases are not the exclusive means of identifying them, and (2) are subject to risks and uncertainties and represent our present expectations or
beliefs concerning future events. VASCO cautions that the forward-looking statements are qualified by important factors that could cause actual results to differ materially from those in the forward-looking statements. These risks, uncertainties and
other factors have been described in greater detail in our Annual Report on Form 10-K for the year ended December 31, 2010 and include, but are not limited to, (a) risks of general market conditions, including currency fluctuations and the
uncertainties resulting from turmoil in world economic and financial markets, (b) risks inherent to the computer and network security industry, including rapidly changing technology, evolving industry standards, increasing numbers of patent
infringement claims, changes in customer requirements, price competitive bidding, and changing government regulations, and (c) risks specific to VASCO, including, demand for our products and services, competition from more established firms and
others, pressures on price levels and our historical dependence on relatively few products, certain suppliers and certain key customers. Thus, the results that we actually achieve may differ materially from any anticipated results included in, or
implied by these statements.

General

The following discussion is based upon our consolidated results of operations for the three and six months ended June 30, 2011 and 2010 (percentages in the discussion may be rounded to the closest full
percentage point) and should be read in conjunction with our consolidated financial statements included elsewhere in this Form 10-Q and our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission.

We design, develop, market and support open standards-based hardware and software security systems that manage and secure access to information
assets. We also design, develop, market and support patented strong user authentication products and services for e-business and e-commerce. Our products enable secure financial transactions to be made over private enterprise networks and public
networks, such as the Internet. Our strong user authentication is delivered via our hardware and software DIGIPASS security products (collectively DIGIPASSES), most of which incorporate an electronic signature capability, which further protects the
integrity of electronic transactions and data transmissions. Some of our DIGIPASSES are compliant with the Europay MasterCard Visa (EMV) standard and are compatible with MasterCards and VISAs Chip Authentication Program (CAP). Some of
our DIGIPASS units comply with the Initiative for Open Authentication (OATH). As evidenced by our current customer base, our products are purchased by companies and, depending on the business application, are distributed to either their employees or
their customers. Those customers may be other businesses or, as an example in the case of Internet banking, our customer banks corporate and retail customers.

##### Table of Contents

We offer our products either through a product sales and licensing model or through our DIGIPASS as a
Service (DPS) product offering. DPS is our cloud-based authentication platform. By using our authentication platform, customers can deploy two-factor authentication more quickly, incur less upfront costs and be able to use strong
authentication when logging onto a larger number of Internet sites and applications. We expect those applications to include business-to-business applications, business to employee applications (e.g., employees of companies logging into third party
applications operated in the cloud), and business to consumer applications. While there were minimal revenues generated from this product in the second quarter of 2011, we believe that DPS has the potential for significant future growth as it will
make two-factor authentication more affordable and readily available to users and application markets.

In January 2011, we acquired
DigiNotar BV. The acquisition expands the technological breadth of our product line by expanding our abilities to offer PKI technology throughout the product line. We expect that acquisition will enhance our market position in three areas;
(1) as a trusted internet service provider of PKI certificates, which we expect will improve our ability to penetrate government markets (2) as a licensor of PKI-based products to customers for use in their applications, which we believe
will enhance our ability to compete in our traditional business and (3) as a provider of our own PKI-secured applications, such as document signing, registration and storage solutions, which we expect will expand opportunities for us on our
services platform.

In April 2011, we acquired Alfa & Ariss BV (Alfa & Ariss). Alfa & Ariss is an
authority in the field of developing open identity and access management solutions. Alfa & Ariss brought additional important know-how and engineering capabilities in the fields of linking applications in-the-cloud. We believe that the
acquisition of Alfa & Ariss will support the long-term growth strategy of our services and enterprise and application security businesses.

Our target market is any business process that uses some form of electronic interface, particularly the Internet, where the owner of that process is at risk if unauthorized users can gain access to its process and
either obtain proprietary information or execute transactions that are not authorized. Our products can not only increase the security associated with accessing the business process, thereby reducing the losses from unauthorized access, but also, in
many cases, can reduce the cost of the process itself by automating activities that were previously performed manually.

Comparison of Results for
the Three Months and Six Months Ended June 30, 2011 and 2010

Industry Growth:We believe that, while there are no
accurate measurements of the total industrys size, the industry is growing and will continue to grow at a significant rate into the foreseeable future. Growth is being driven by new government regulations, growing awareness of the impact of
identity theft, and the growth in commerce that is transacted electronically. The issues driving the growth are global issues and the rate of adoption in each country is a function of that countrys culture, the competitive position of
businesses operating in that country, the countrys overall economic conditions and the degree to which businesses and consumers within the country use technology. While industry growth in 2010 was uneven in the various countries in which we
operate, we experienced an increase in requests for information and proposals throughout the year and an increase in order intake, especially in the second half of 2010. We believe that the industry has returned to more normal growth in 2011 as both
our order intake and our pipeline of potential future deals continued strong in the first half of 2011.

Economic Conditions:Our
revenue may vary significantly with changes in the economic conditions in the countries in which we sell products. With our current concentration of revenue in Europe and specifically in the banking/finance vertical market, significant changes in
the economic outlook for the European banking market may have a significant effect on our revenue.

Starting in the fourth quarter of
2009, we received an increase in the number of requests for information and requests for proposals. That increase in activity started to manifest itself into a strong order flow in the second half of 2010 and into the first half of 2011. As a result
of the increase in orders, we realized a sequential increase in revenue in each of the last four quarters. Also, with the

##### Table of Contents

apparent abatement of the difficult economic conditions in the fourth quarter of 2009 in many of the countries in which we operate, we initiated a plan to hire staff to support new product
development, support new sales initiatives and mitigate risk while strengthening our position in existing markets. These actions continued throughout 2010 and resulted in lower operating earnings as a percentage of revenue in 2010. These actions are
also expected to result in lower operating income as a percentage of revenue in 2011, but we believe that these actions allowed us to strengthen our overall market position and are expected to result in higher revenue and higher operating earnings
in future years.

Currency Fluctuations: In the second quarter of 2011 and 2010, approximately 94% and 89%, respectively, of our
revenue was generated outside the United States. For the six months ended June 30, 2011 and 2010, approximately 94% and 90%, respectively, of our revenue was generated outside of the United States.

In addition, in the second quarter of 2011 and 2010, approximately 82% and 80%, respectively, of our operating expenses were incurred outside the
United States. For the six months ended June 30, 2011 and 2010, approximately 82% and 81%, of our operating expenses were incurred outside of the United States.

Changes in currency exchange rates, especially the Euro to U.S. Dollar, can have a significant impact on revenue and expenses.In general, to minimize the net impact of currency fluctuations, we attempt to
denominate our billings in a currency such that it would provide a hedge against the operating expenses being incurred in that currency. We expect that changes in currency rates may also impact our future results if we are unable to match amounts of
revenue with our operating expenses in the same currency. In periods in which the U.S. Dollar is weakening, we expect that our operating earnings will increase as a result of the change in currency exchange rates. Conversely, in periods in
which the U.S. Dollar is strengthening, we expect that our operating earnings will decrease as a result of the change in currency exchange rates.

The U.S. Dollar weakened by approximately 10% against the Euro for the quarter ended June 30, 2011 and weakened approximately 4% against the Euro for the six months ended June 30, 2011 as compared to
the same periods in 2010. The U.S. Dollar weakened 16% and 14% against the Australian Dollar for the quarter and six months ended June 30, 2011, respectively, as compared to the same periods in 2010. We estimate that the changes in the
exchange rate of the U.S. Dollar to these two currencies in 2011 compared to 2010 resulted in an increase in revenue and operating expenses of approximately $2,345 and $1,675, respectively, for the quarter ended June 30, 2011 and an
increase in revenue and operating expenses of approximately $2,301 and $1,406, respectively, for the six months ended June 30, 2011 compared to the same periods in 2010.

The financial position and results of operations of most of our foreign subsidiaries, with the exception of our subsidiaries in Switzerland and Singapore (in which the functional currency is the U.S. Dollar), are
generally measured using the local currency as the functional currency. Accordingly, assets and liabilities are translated into U.S. Dollars using current exchange rates as of the balance sheet date. Translation adjustments arising from differences
in exchange rates are included as a separate component of stockholders equity. Revenue and expenses are translated at average exchange rates prevailing during the period. Gains and losses resulting from foreign currency transactions are
included in the consolidated statements of operations in other non-operating income (expense). Foreign exchange transaction gains aggregating $30 and $58 in the second quarter and first six months of 2011, respectively, compare to losses aggregating
of $118 and $267, respectively, in the second quarter and first six months of 2010.

Revenue by Geographic Regions:We classify our sales by customers location in four geographic regions: 1) EMEA, which includes Europe, the Middle East and Africa; 2) the United States, which for our
purposes includes sales in Canada; 3) Asia Pacific; and 4) Other Countries, including Australia, Latin America and Central Asia. The breakdown of revenue for the three and six months ended June 30, 2011 and 2010 in each of our major
geographic regions follows:

Total revenue in the second quarter of 2011 increased $18,239, or 74%, from the second quarter of 2010. Including
the impact of changes in currency exchange rates, the increase was primarily attributable to a 114% increase in revenues from the banking market partially offset by an 8% decline in revenues from the enterprise and application security market. As
noted above, for the quarter ended June 30, 2011, we estimate that the weakening of the U.S. Dollar as compared to the Euro resulted in a increase in revenue of $2,345.

Revenue generated in EMEA during the second quarter of 2011 was $16,580, or 102%, higher than the second quarter of 2010. Revenue from the banking
market for the second quarter of 2011 was approximately 135% higher than in the same period of 2010 while revenues from the enterprise and application security market were approximately 22% higher.

Revenue generated in the United States during the second quarter of 2011 was $11, or less than 1%, lower than the second quarter of 2010. In the
second quarter of 2011, increases in revenues from the banking market were offset by declines in the enterprise security market.

Revenue generated in the Asia Pacific region during the second quarter of 2011 was $127, or 5%, higher than the second quarter of 2010. The
increase in revenues reflected growth in the banking market partially offset by a decline in revenues from the enterprise and application security market.

Revenue generated from other countries during the second quarter of 2011 was $1,543, or 47%, higher than the second quarter of 2010. The increase in other countries was primarily due to increases in revenue from
the banking market in South America partially offset by declines in the enterprise and application security market in Australia. In the second quarter of 2010, we had several transactions in the enterprise and application security market that have
not been replaced by

comparable orders from similar customers or from new customers or new applications. We expect that revenues from other countries will be more volatile than from our other regions given their
earlier stage of development of the authentication market in those countries. VASCO, however, plans to continue to invest in new markets based on our estimates of each markets demand for strong user authentication.

Total revenue for the six months ended June 30, 2011 increased $30,683, or 63%, from the first six months of 2010. Including the impact of
changes in currency exchange rates, the increase was primarily attributable to a 92% increase in revenues from the banking market partially offset by a 6% decline from the enterprise and application security market. As noted above, for the six
months ended June 30, 2011, we estimate that the weakening of the U.S. Dollar as compared to the Euro resulted in an increase in revenue of $2,301.

Revenue for the six months ended June 30, 2011 generated in EMEA was $26,851, or 83%, higher than the comparable period in 2010. Revenue from the banking market for the first six months of 2011 was
approximately 112% higher than in the same period of 2010 while revenues from the enterprise and application security market were approximately 12% higher.

Revenue for the six months ended June 30, 2011 generated in the United States was $146, or 3%, higher than the comparable period in 2010. Revenues from the U.S. for the first six months of 2011 generally
followed the results noted above for the second quarter, growth in the banking market largely offset by declines in the enterprise and application security market.

Revenue for the six months ended June 30, 2011 from Asia Pacific was $1,313, or 35%, higher than the comparable period in 2010. Revenues from Asia Pacific for the first six months of 2011 generally followed
the results noted above for the second quarter, which reflected growth in the banking market partially offset by declines in the enterprise and application security market.

Revenue for the six months ended June 30, 2011 generated from other countries was $2,373, or 31%, higher than the comparable period in 2010, reflecting growth in revenue from the banking market partially
offset by the decline in revenue from the enterprise and application security market as noted above for the second quarter.

Revenue by Target Market:Revenue is generated currently from two primary markets,
banking/finance and enterprise and application security, through the use of both direct and indirect sales channels. The enterprise and application security market includes corporations, business-to-business, business-to-consumer, e-commerce,
e-government, services revenues, including DigiNotar, and various other vertical application markets that are not related to banking or finance. The breakdown of revenue between the two primary markets was as follows:

Revenue in the second quarter of 2011 from the banking market increased $18,898, or 114%, from the second quarter
of 2010 and revenue from the enterprise and application security market decreased $659, or 8%, in the same period.

The increase in the
banking market in the second quarter of 2011 compared to 2010 primarily reflects a strong increase in demand for our solutions, especially in Europe and the weakening of the U.S. Dollar as compared to the Euro, as previously noted. We believe
that the increase in revenue in the banking market reflected a return by the banks to their more traditional ways of doing business (e.g., larger orders for delivery over several quarters) following the banking crisis and economic slowdown that
started in the fourth quarter of 2008.

We believe that the decrease in revenue in the enterprise and application security market
primarily relates to weak demand from the application security market. Large orders in the prior years quarter from applications such as gaming and/or government have not been replaced by comparable orders from similar customers or from new
customers or new applications. Also, given the amount of our revenue from the enterprise and application security market, the absence of significant transactions can produce a large variation on a percentage basis compared to prior periods. We
believe that our revenues will improve as a result of programs designed to support our reseller channel and their efforts.

Revenue for
the first six months of 2011 from the banking market increased $31,482, or 92%, compared to the first six months of 2010 while revenue for the enterprise and application security market decreased $799 or 6% in the same period. The changes in results
from the two markets primarily reflect the same issues as noted above relative to the comparison of the second quarter of 2011 to the second quarter of 2010.

Gross Profit

Consolidated gross profit for the quarter ended June 30, 2011 was $26,304, an increase of $8,868, or 51%, from the quarter ended June 30,
2010. Gross profit as a percentage of revenue (gross profit margin) was 61% for the quarter ended June 30, 2011, as compared to 71% for the quarter ended June 30, 2010.

Consolidated gross profit for the six months ended June 30, 2011 was $48,984, an increase of $14,860, or 44%, from the comparable period in
2010. Gross profit as a percentage of revenue (gross profit margin) was 62% for the six months ended June 30, 2011, as compared to 70% for the comparable period in 2010.

The decrease in gross profit as a percentage of revenue for the second quarter and first six months of 2011 compared to the comparable periods in 2010 primarily reflects:



| |  |  | a decrease in revenue and a decrease in the percentage of our total revenue that came from the enterprise and application security market,
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | a decrease in gross profit margin from revenue from the banking market,
| | - |  | -----------------------------------------------------------------------

| |  |  | an increase in freight costs associated with expedited delivery of products to the banking market, and

| |  |  | a decrease in non-hardware revenues as a percentage of total revenue,

partially offset by



| |  |  | the positive impact on revenue and gross profit margin of changes in foreign currency rates.
| | - |  | --------------------------------------------------------------------------------------------

Revenue from our enterprise and application security market, which generally has margins that are 20 to 30 percentage points higher than the
banking market, was 17% of our total revenue in the second quarter and for the first six months of 2011 compared to 33% and 30% for the second quarter and first six months of 2010. We expect continued strong growth in revenues from the banking
market in 2011. We expect that our revenues from the enterprise and application security market as a percentage of total revenue will continue to be below the comparable quarters of 2010.

The decline in gross profit margin from the banking market reflected both an increase in large orders and an unfavorable mix of the products sold
to the banking market for both the second quarter and first six months of 2011 compared to the comparable period in 2010. The reduction in the gross profit margin related to the larger orders is consistent with our approach to pricing, which is to
offer lower average selling prices per unit for large volume purchase orders. The unfavorable mix of products reflects the fact that card readers, which can have a lower gross profit margin that is approximately 25 to 35 percentage points lower than
other hardware-related margins due to competitive pricing pressures, were 26% and 22% of our revenue for the second quarter and first six months of 2011, respectively, compared to 13% and 14% for the same periods in 2010. While we expect that both
the size of the orders shipped and the quantity of card readers shipped will continue to be factors in our results for future quarters, the degree of impact in any given quarter will depend on the specific quantity and mix of product sold in any
given quarter. In particular, we expect that the relatively low gross profit margin on card readers will continue into the foreseeable future, as there are a number of competitors in the EMV (Europay, MasterCard and Visa) market that produce card
reader products with fewer features than our products at a lower cost.

In addition, due to the high customer demand from our banking
customers, in conjunction with the time needed to source critical product components and ramp up production, we bore the incremental costs of shipping the product from our manufacturers in China to some our customers on an expedited basis to meet
our customers requirements. We expect that the amount of freight costs related to expedited shipments will decline in future quarters as our production ramps up to more normalized levels.

Non-hardware revenue, which can have a gross profit margin that is approximately 20 to 30 percentage points higher than hardware-related revenue,
depending on the model and quantity of the hardware units sold, was 22% of revenue for both the second quarter and first six months of 2011 and compares to approximately 27% and 26% of total revenue for the second quarter and first six months of
2010, respectively. We plan to continue to focus on sales of our non-hardware revenue items and expect that they will increase as a percentage of our total revenue in future periods.

The majority of our inventory purchases are denominated in U.S. Dollars. Also, as previously noted, our sales are denominated in various currencies
including the Euro and Australian Dollar. As the U.S. Dollar has weakened, when compared to the Euro and Australian Dollar in the same periods in the prior year, revenue from sales made in Euros and Australian Dollars increased, as measured in
U.S. Dollars, without the corresponding increase in cost of goods sold. The impact from changes in currency rates as noted above are estimated to have increased revenue by approximately $2,345 and $2,301 for the second quarter and first six months
of 2011, respectively. Had the currency rates in 2011 been equal to the rates in 2010, the gross profit rate would have been approximately 2.2 percentage points lower for the quarter and 1.1 percentage points lower for the six months ended
June 30, 2011.

We plan to continue investing in both the banking and enterprise and application security markets. In
addition, we are investing in our DIGIPASS as a Service product line and integrating our acquisitions of DigiNotar and Alfa & Ariss. We believe that our gross profit margin will improve as the growth rate from our enterprise and application
security business improves and our Services business gains traction.

Operating Expenses

Our operating expenses are generally based on anticipated revenue levels and the majority of such expenses are fixed over short periods of time. As
a result, small variations in the amount of revenue recognized in any given quarter could cause significant variations in the quarter-to-quarter comparisons of either the absolute amounts of operating income or operating income as a percentage of
revenue.

The most significant factor driving our operating expenses is our headcount. Direct compensation and benefit plan expenses
generally represent between 55% and 60% of our operating expenses. In addition, a number of other expense categories are directly related to headcount.

On a consolidated basis, our operating expenses for the quarter and six months ended June 30, 2011 were $22,904 and $42,515, respectively, an increase of $7,044, or 44%, from the second quarter of 2010 and an
increase of $10,691, or 34%, for the six months ended June 30, 2011. The increase in consolidated operating expenses was primarily related to the impact of our hiring program in 2010, our acquisitions of DigiNotar in January of 2011 and
Alfa & Ariss in April of 2011, and the impact of changing currency exchange rates.

During the first quarter of 2010, in
anticipation of strong growth in our markets in the later part of 2010 and into 2011, we began an aggressive hiring program that resulted in an increase in our staff by 48 persons, or approximately 16% for the full year 2010. As a result, our
average headcount, excluding the headcount associated with our acquisitions of DigiNotar and Alfa & Ariss, for the second quarter and first six months of 2011 were 13% and 14% higher, respectively, than the same periods in 2010.

Operating expenses associated with the acquisitions of DigiNotar and Alfa & Ariss were approximately $1,891 and $3,442 for the second
quarter and first six months of 2011, respectively. Operating expenses included $1,255 of expenses related to operations and $636 related to the amortization of purchased intangible assets for the second quarter of 2011. Operating expenses included
$2,245 related to operations and $1,197 related to the amortization of purchased intangible assets for the six months ended June 30, 2011.

As noted above, we estimate that the changes in currency exchange rates, primarily the strengthening of the Euro and Australia Dollar compared to the U.S. Dollar, increased our operating expenses by $1,675 and
$1,406 for the second quarter and six months ended June 30, 2011, respectively, compared to the same periods in 2010.

Excluding
the impact of DigiNotar, Alfa & Ariss and changes in currency, operating expenses increased $3,478, or 22% for the second quarter and $5,843 or 18% for the six months ended June 30, 2011 over the same periods in 2010.

Sales and Marketing Expenses

Consolidated
sales and marketing expenses for the quarter ended June 30, 2011 were $11,469, an increase of $3,742, or 48%, from the second quarter of 2010. The increase in sales and marketing expenses primarily reflects:



| |  |  | increased compensation expenses related to an increase in average headcount,

Consolidated sales and marketing expenses for the six months ended June 30, 2011, were $20,982, an increase of $5,326, or 34%, from the same period of 2010. The increase in expense was generally related to the
same factors noted for the second quarter above.

Average sales and marketing employee headcount in the second quarter and first six
months of 2011, including headcount related to DigiNotar, was 204 and 192, respectively, compared to 160 and 158 for the comparable periods in 2010.

Research and Development Expenses

Consolidated research and development expenses for the quarter ended June 30, 2011, were $5,088, an increase of $1761, or 53%, from the second
quarter of 2010. This increase was primarily due to:



| |  |  | increased compensation expense,
| | - |  | -------------------------------

| |  |  | increased purchased services,
| | - |  | -----------------------------

| |  |  | DigiNotar and Alfa & Ariss operating expenses, and
| | - |  | --------------------------------------------------

| |  |  | the impact of changes in currency exchange rates.
| | - |  | -------------------------------------------------

Consolidated research and development costs for the six months ended June 30, 2011, were $9,145, an increase of $2,547, or 39%, from the same period of 2010. The increase in expense was generally related to
the same factors noted for the second quarter above.

Average research and development employee headcount in the second quarter and
first six months of 2011, including headcount related to DigiNotar and Alfa & Ariss, was 140 and 131, respectively, compared to 102 and 98 for the comparable periods in 2010.

General and Administrative Expenses

Consolidated general and administrative expenses for the
quarter ended June 30, 2011, were $5,640, an increase of $942, or 20%, from the second quarter of 2010. This increase is primarily due to:



| |  |  | increased compensation expenses related to an increase in average headcount,
| | - |  | ----------------------------------------------------------------------------

| |  |  | DigiNotar operating expenses, and
| | - |  | ---------------------------------

| |  |  | the impact of changes in currency exchange rates.

Consolidated general and administrative expenses for the six months ended June 30, 2011, were $11,001, an increase of $1,654 or 18%, from the same period of 2010. The increase in expense was generally related
to the same factors noted for the second quarter above.

Average general and administrative employee headcount in the second quarter and
first six months of 2011, including headcount related to DigiNotar, was 67 and 63, respectively, compared to 53 and 51 for the comparable periods in 2010.

Amortization of Purchased Intangible Assets

Amortization of intangible assets for the second quarter of 2011 increased $599, or 555% over the comparable period in 2010. The increase in
amortization expense reflects the impact of the amortization of the purchased intangible assets resulting from our acquisition of DigiNotar and Alfa & Ariss.

Amortization of intangible assets for the six months ended June 30, 2011 increased $1,164, or 522% over the comparable period in 2010 and was attributable to the acquisitions of DigiNotar and Alfa &
Ariss.

Interest Income

Consolidated net interest income was $124 in the second quarter of 2011 as compared to income of $63 in the second quarter of 2010. For the six
months ended June 30, 2011, interest income was $236 compared to $134 for the same period of 2010. The increase in interest income reflects the combination of higher interest rates paid on higher invested cash balances. Our average cash balance
in the second quarter and first six months of 2011 of $85,611 and $84,271 was 13% and 15%, higher, respectively, than in the second quarter and first six months of 2010.

Other Income (Expense), Net

Other income (expense) primarily includes exchange gains (losses)
on transactions that are denominated in currencies other than our subsidiaries functional currencies, subsidies received from foreign governments in support of our export business in those countries and other miscellaneous non-operational,
non-recurring expenses.

Other income for the second quarter of 2011 was $319 and compares to other income of $142 for the second
quarter of 2010. The increase in other income primarily reflects exchange gains of $30 in the second quarter of 2011 compared to exchange losses of $118 in the second quarter of 2010.

Other income for the first six months of 2011 was $610 and compares to $202 for the first six months of 2010. The increase in other income
(expense) primarily reflects exchange gains of $58 in the first six months of 2011 compared to exchange losses of $267 in the first six months of 2010

Income Taxes

Income tax expense for the
second quarter of 2011 was $1,222, an increase of $837 from the second quarter of 2010. The increase in tax expense is attributable to higher pre-tax income and higher effective tax rate. The effective tax rate was 32% for the second quarter of 2011
and compares to 22% for the second quarter of 2010. The tax rate in the second quarter of 2011 was negatively impacted by an increase in our estimate of our full-year tax rate, from 28% in the first quarter to 30% in the second quarter. The increase
in our estimated full-year tax rate reflected a decline in our forecasted pretax income in jurisdictions with low effective tax rates. The tax rate for the second quarter of 2010 benefited from $256 of discrete items related to the true-up of our
provisions to prior year tax returns as filed and other tax adjustments.

Income tax expense for the first six months of 2011 was
$2,194, an increase of $1,527 from the same period in 2010. The increase in tax expense reflects higher pre-tax income and a higher effective tax rate. The full-year estimated effective tax rate at the end of the second quarter, including the
benefit of discrete items noted above, was 30% and 25% for 2011 and 2010, respectively.

The effective tax rate for both periods
reflects our estimate of our full-year tax rate at the end of each respective period. The increase in the tax rate is primarily attributable to a reduction in pretax profits in tax jurisdictions that either have a lower statutory tax rate or have
tax loss carryforwards that have been reserved. We believe that our effective tax rate may vary significantly quarter to quarter as actual earnings or losses are realized in countries with lower tax rates or with loss carryforwards that have been
reserved.

##### Table of Contents

At December 31, 2010, we had U.S. net operating loss (NOL) carryforwards of $21,247. Of this
amount, $14,727 would result in a benefit to earnings. The remainder represents tax deductions for employee stock option gains which would be credited to paid-in capital. The U.S. loss carryforwards expire in varying amounts beginning in 2020 and
continuing through 2029. In addition, if certain substantial changes in the companys ownership were deemed to have occurred, there would be an annual limitation on the amount of the U.S. carryforwards that could be utilized. At
December 31, 2010, we also had foreign NOL carryforwards of $4,834. The foreign NOL carryforwards have no expiration dates. A valuation reserve has been provided for the U.S. and certain foreign operating loss carryforwards to offset the future
benefits because we have not determined that their realization is more likely than not.

Liquidity and Capital Resources

Our net cash balance was $84,630 at June 30, 2011, a decrease of $1,392, or 2%, from $86,022 at March 31, 2011, and a decrease of $903, or
1%, from $85,533 at December 31, 2010. The decrease in cash from March 31, 2011, was attributable to the purchase of Alfa & Ariss and an increase in other key elements of working capital, partially offset by the positive impact of
change in exchange rates. The positive impact of changes in exchange rates primarily reflected the fact that the Euro strengthened against the U.S. dollar. At June 30, 2011, the exchange rate for the Euro to U.S. dollar was at 1.44 and compares
to 1.41 at March 31, 2011 and 1.33 at December 31, 2010. We believe that our cash resources will be sufficient to meet our operating needs for the next twelve months.

At June 30, 2011 we had working capital of $93,906, an increase of $3,083, or 3%, from $90,823 at March 31, 2011 and a decrease of
$2,983, or 3% from $96,889 reported at December 31, 2010. The decrease in working capital from December 31, 2010 was primarily related to the acquisitions of DigiNotar and Alfa & Ariss.

EBITDA from continuing operations for the three and six month periods ending June 30, 2011 was $5,270 and $9,751, an increase of $3,022 and
$5,987, respectively over the same periods in the prior year. A reconciliation of EBITDA to net income for the quarter and six months ended June 30, 2011, and 2010 follows:

EBITDA is a non-GAAP financial measure within the meaning of applicable U.S. Securities and Exchange Commission
rules and regulations. We use EBITDA as a measure of performance, a simplified tool for use in communicating our performance to investors and analysts and for comparisons to other companies within our industry. As a performance measure, we believe
that EBITDA presents a view of our operating results that is most closely related to serving our customers. By excluding interest, taxes, depreciation and amortization we are able to evaluate performance without considering decisions that, in most
cases, are not directly related to meeting our customers

requirements and were either made in prior periods (e.g., depreciation and amortization), or deal with the structure or financing of the business (e.g., interest) or reflect the application of
regulations that are outside of the control of our management team (e.g., taxes). Similarly, we find that the comparison of our results to those of our competitors is facilitated when we do not need to consider the impact of those items on our
competitors results.

EBITDA should be considered in addition to, but not as a substitute for, other measures of financial
performance reported in accordance with accounting principles generally accepted in the United States. While we believe that EBITDA, as defined above, is useful within the context described above, it is in fact incomplete and not a measure that
should be used to evaluate our full performance or our prospects. Such an evaluation needs to consider all of the complexities associated with our business including, but not limited to, how past actions are affecting current results and how they
may affect future results, how we have chosen to finance the business and how regulations and the other aforementioned items affect the final amounts that are or will be available to shareholders as a return on their investment. Net income
determined in accordance with U.S. GAAP is the most complete measure available today to evaluate all elements of our performance. Similarly, our Consolidated Statement of Cash Flows, which will be filed as part of our annual report on Form 10-K,
provides the full accounting for how we have decided to use resources provided to us from our customers, lenders and shareholders.

While we believe that our financial resources are adequate to meet our operating needs for the next twelve months, we anticipate that the difficult
current economic conditions that exist on a worldwide basis today may require us to modify our business plans. In the current economic environment there is an increased risk that customers may delay their orders until the economic conditions
stabilize or improve. If a significant number of orders are delayed for an indefinite period of time, our revenue and cash receipts may not be sufficient to meet the operating needs of the business. If this is the case, we may need to significantly
reduce our workforce, sell certain of our assets, enter into strategic relationships or business combinations, discontinue some or all of our operations, or take other similar restructuring actions. While we expect that these actions would result in
a reduction of recurring costs, they also may result in a reduction of recurring revenue and cash receipts. It is also likely that we would incur substantial non-recurring costs to implement one or more of these restructuring actions. For additional
information related to risks, refer to Certain Factors noted in Managements Discussion and Analysis included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2010.

Recently Issued Accounting Pronouncements

Software

In October 2009, the FASB issued ASU 2009-14, Software, Certain Revenue Arrangements That Include Software Elements. ASU
2009-14 provides guidance to determine if products should be accounted for as software under ASC 985-605. Arrangements that are no longer defined as software are accounted for under ASC 605-25, for separating consideration in multiple-deliverable
arrangements. Under ASU 2009-14, tangible products containing software components and non-software components that function together to deliver the tangible products essential functionality will no longer fall within the scope of ASC 985-605.

Revenue Recognition

In October
2009, the FASB issued ASU 2009-13, Multiple-Deliverable Revenue Arrangements. ASU 2009-13 amends the criteria in ASC 605-25 for separating consideration in multiple-deliverable arrangements and provides the ability to separate deliverables in
more circumstances than was previously allowed under U.S. GAAP. In addition, the amendments in ASU 2009-13 established a selling price hierarchy for determining the selling price of a deliverable. The selling price used for each deliverable is based
on VSOE if available, third-party evidence if VSOE is not available, or estimated selling price if neither VSOE or third-party evidence is available. Under this update, the term fair valuewas replaced with selling price to clarify
that the allocation of revenue is based on entity-specific assumptions rather than assumptions of a marketplace participant.

##### Table of Contents

ASU 2009-13 also eliminates the residual method of allocation and requires that arrangement
consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The relative selling price method allocates any discount in the arrangement proportionally to each deliverable on the basis
of each deliverables selling price.

Both ASU 2009-13 and ASU 2009-14 were effective prospectively for revenue arrangements
entered into or materially modified in fiscal years beginning on or after June 15, 2010. We adopted both Updates effective January 1, 2011. As a result of adoption of the Updates:



| | 1. | The sales of some of our products are defined as software sales and continue to be accounted for using ASC 985-605. Sales of some of our other products, however, no longer
qualify as sales of software and are accounted for under ASC 605-25.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | For items continuing to be classified as software, we do not expect that the allocation of consideration will be significantly different than prior to adoption as we have
vendor-specific objective evidence for the most common type of undelivered items, such as maintenance and support. Further, we continue to use the Residual Method when we have vendor-specific objective evidence of any undelivered elements.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | For sales of products that no longer qualify as software sales, we allocate the arrangement consideration among each of the accounting units based on relative selling price of
each of the units with any discount on the transaction being split proportionately between delivered and undelivered accounting units. We do not expect that the allocation of purchase price among delivered and undelivered elements to be
significantly different than under our accounting practices prior to adoption because, as noted above, we have vendor-specific objective evidence for the most common type of undelivered items and generally do not provide discounts that will
significantly impact the value determined using VSOE.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For the three and six months ended June 30, 2011, the adoption
of ASU 2009-13 and ASU 2009-14 did not have a significant impact on revenue. Further, we do not expect that adopting ASU 2009-13 and ASU 2009-14 will have a material impact on the amount, pattern or timing of the recognition of future revenue.

From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted by us as of
the specified effective date. Unless otherwise discussed, our management believes that the impact of recently issued standards that are not yet effective will not have a material impact on our consolidated financial statements upon adoption.



|Item 3. | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------

There have been no material changes in our market risk during the three months ended June 30, 2011. For additional information, refer to Item 7A. Quantitative and Qualitative Disclosures about Market
Risk, included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2010.



|Item 4. | Controls and Procedures
|------- | -----------------------

Our management, with
the participation of our Chief Executive Officer and Chief Financial Officer, who, respectively, are our principal executive officer and principal financial officer, conducted an evaluation of the effectiveness of our disclosure controls and
procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the Exchange Act)) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation,
our Chief Executive Officer and Chief Financial Officer concluded that as of the end of the period covered by this Quarterly Report on Form 10-Q our disclosure controls and procedures were

effective to provide reasonable assurance that (i) the information required to be disclosed by us in our reports that we file or submit under the Exchange Act is recorded, processed,
summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and forms, and (ii) information required to be disclosed by us in our reports that we file or submit under the Exchange Act is
accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Controls

There were no
changes in our internal control over financial reporting (as that term is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter ended June 30, 2011, that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.

Inherent Limitations on the Effectiveness of Controls

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. However, our management,
including our Chief Executive Officer and Chief Financial Officer, do not expect that our disclosure controls and procedures or internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well
designed and implemented, can provide only reasonable, not absolute, assurance that the control systems objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits
of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company are
detected. The inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons,
by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will
succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in
conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.
