LIGHTBRIDGE, INC. AND SUBSIDIARIES

     In accordance with Statement of Financial Accounting Standard No. 142 (SFAS 142), the Company is required to analyze the carrying value of goodwill and other intangible assets for impairment issues on an annual basis. The Company will evaluate its carrying value of goodwill and other intangible assets against the estimated fair value of those assets. If impairment has occurred, the Company will record a charge in the amount by which the carrying value of the assets exceeds their estimated fair value. Estimated fair value will generally be determined based on discounted cash flows.

Pro forma financial information

     The following table presents the unaudited pro forma financial information of the Company including Authorize.Net for the three months ended March 31, 2004 and 2003, as if the acquisition had occurred on January 1, 2003, after giving effect to certain purchase accounting adjustments.

      The pro-forma net income for the three months ended March 31, 2004 excludes the write-off of IPR&D of $0.7 million related to the Authorize.Net acquisition. These results are presented for illustrative purposes only and are not necessarily indicative of the actual operating results or financial position that would have occurred if the transaction had been consummated on January 1, 2003.

3. CONTINGENCIES

      At March 31, 2004, the Company was holding funds in the amount of $6.4 million on behalf of merchants utilizing Authorize.Net’s eCheck services. The funds are included in cash and cash equivalents and funds due to merchants on the Company’s condensed consolidated balance sheet. Authorize.Net typically holds eCheck funds for approximately seven business days; the actual number of days depends on the contractual terms with each merchant. In addition, the Company currently has $0.6 million on deposit with the financial institution. The deposits are held to cover any deficit account balance that could occur if the amount of transactions returned or charged back exceeds the balance on deposit with the financial institutions. To date, the deposits have not been applied to offset any deficit balance, and management believes that the likelihood of incurring a deficit balance with the financial institutions due to the amount of transactions returned or charged back is remote. The deposit will be held continuously for as long as Authorize.Net utilizes the ACH processing services of the financial institution, and the amount of the deposit may increase as processing volume increases.

      At March 31, 2004, the Company held funds in the amount of $0.7 million for and on behalf of merchants processing credit card and ACH transactions using the Integrated Payment Solution (IPS) product. The funds are included in cash and cash equivalents and funds due to merchants on the Company’s condensed consolidated balance sheet. Credit card funds are typically held for approximately two business days; ACH funds are held for approximately four business days, according to the specifications of the product and the contract between Authorize.Net and the financial institution through which the transactions are processed.

      On February 10, 2004, the Company entered into a lease agreement with the Region of Queens Municipality to lease 32,144 square feet of space in Liverpool, Nova Scotia, Canada. The lease runs through April 30, 2009, with an option to renew at the end of the current lease term. The lease also gives the Company the right to terminate upon the third anniversary thereof. The future minimum commitments under this lease are as follows:

4. STOCK-BASED COMPENSATION

     The Company applies the intrinsic value based method of accounting for stock options granted to employees. The Company accounts for stock options and awards to non-employees using the fair value method.

     Under the intrinsic value method, compensation associated with stock awards to employees is determined as the difference, if any, between the current fair value of the underlying common stock on the date compensation is measured and the price an employee must pay to exercise the award. The measurement date for employee awards is generally the date of grant. Under the fair value method, compensation associated with stock awards to non-employees is determined based on the estimated fair value of the award itself, measured using either current market data or an established option pricing model. The measurement date for non-employee awards is generally the date of grant.

     Had the Company used the fair value method to measure such compensation expense associated with grants of stock options to employees, reported net loss and basic and diluted loss per share would have been as follows:

6

     The fair value of options on their grant date was measured using the Black-Scholes Option Pricing Model. Key assumptions used to apply this pricing model for the three-month periods ended March 31, 2004 and 2003 are as follows:

     It should be noted that the option-pricing model used was designed to value readily tradable stock options with relatively short lives. The options granted to employees are not tradable and have contractual lives of up to ten years.

5. REVENUE RECOGNITION

     The Company generates revenue from the processing of qualification and activation transactions; granting of software licenses; services (including maintenance, installation and training); development and consulting contracts; and hardware sold in conjunction with certain software licenses. Revenues from processing of qualification and activation transactions for communication providers are recognized in the period in which services are performed.

     The Company’s software license agreements have typically provided for an initial license fee and annual maintenance based on a defined number of subscribers, as well as additional license and maintenance fees for net subscriber additions in certain circumstances. Revenue from software license sales is recognized when persuasive evidence of an arrangement exists, delivery of the product has been made, and a fixed fee and collectibility have been determined. To the extent that obligations exist for other services, the Company allocates revenue between the license and the services based upon their relative fair value or by the residual method.

     Revenues from consulting and services contracts are generally recognized as the services are performed. Revenues from software maintenance contracts are recognized ratably over the term of the maintenance agreement and are reported as consulting and services revenues. Revenue from hardware sales is recognized upon shipment, unless testing, integration or implementation services are required, in which case hardware revenue is recognized upon commissioning and acceptance of the product. Revenue from hardware sold in conjunction with software licenses are deferred until the related license revenue is recognized.

6. EARNINGS PER SHARE (EPS)

     Basic EPS is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock.

7

     A reconciliation of the shares used to compute basic income per share to those used for diluted income per share is as follows:

     Stock options for which the exercise price exceeds the average market price over the period have an anti-dilutive effect on EPS and, accordingly, are excluded from the diluted computations for both periods presented. Had such shares been included, shares for the diluted computation would have increased by approximately 3,053,000 and 3,118,000 for the periods ended March 31, 2004 and 2003, respectively.

     In addition, all other stock options and warrants convertible into common stock have been excluded from the diluted EPS computations for both periods presented, as they are anti-dilutive due to the net loss recorded by the Company in each period. Had such shares been included, the number of shares for the diluted computation would have increased by approximately 206,000 and 261,000 shares for the quarters ended March 31, 2004 and March 31, 2003, respectively.

7. REPURCHASE OF SHARES

     On October 4, 2001, Lightbridge announced that its board of directors authorized the repurchase of up to 2 million shares of the Company’s common stock at an aggregate price of up to $20 million. The shares may be purchased from time to time on or after October 8, 2001, depending on market conditions. On April 23, 2003, the board approved an expansion of the plan to authorize Lightbridge to purchase up to 4 million shares of the Company’s common stock at an aggregate price of up to $40 million through September 26, 2005. As of March 31, 2004, the Company had purchased approximately 2.0 million shares at a total cost of approximately $14.9 million since the inception of its repurchase program.

     The following summarizes the purchases during the first quarter of 2004:

8. RESTRUCTURING RESERVES

     In June 2002, the Company announced that it was reducing its workforce by seven percent and consolidating its Waltham, Massachusetts call center operations into its Lynn, Massachusetts and Broomfield, Colorado facilities by the end of 2002. The Company recorded a restructuring charge of approximately $3.6 million, consisting of $1.6 million for workforce reductions, $1.3 million for facilities reductions including lease obligations, utilities and security costs on unused space and $0.7 million for capital equipment write-offs associated with these measures. The restructuring plan resulted in the termination of 65 personnel as follows: 25 in product and service delivery, 22 in development, 11 in sales and marketing and seven in general and administrative. The capital equipment write-offs and a majority of severance costs related to this restructuring were incurred by the end of 2002, and the Company anticipates that all other costs relating to this restructuring, consisting principally of lease obligations on unused space, will be paid by the end of 2004.

     The following summarizes the changes to the June 2002 restructuring reserves for the three months ended March 31, 2004:

     In March 2003, the Company announced that it would be streamlining its existing Broomfield, Colorado call center operations into its Lynn, Massachusetts facility and a smaller facility in Broomfield, Colorado by the end of May 2003. In the quarter ended March 31, 2003, the Company recorded a restructuring charge of approximately $0.1 million for workforce reductions. In the quarter ended June 30, 2003, the Company recorded an additional restructuring charge associated with this action of approximately $1.0 million, consisting of approximately $0.6 million in future lease obligations for unused facilities and approximately $0.4 million for capital equipment write-offs. The capital equipment write-offs and a majority of severance costs related to this restructuring were incurred by the end of 2003, and the Company anticipates that all other costs relating to this restructuring, consisting principally of lease obligations on unused space, will be paid by the end of 2004.

     The following summarizes the changes to the March 2003 restructuring reserves for the three months ended March 31, 2004:

     In June 2003, the Company announced that it would be closing its Irvine, California facility and transferring certain employment positions to its Broomfield, Colorado facility and reducing its headcount by an estimated 70 employees as follows: 16 in product and service delivery, 30 in development, 13 in sales and marketing and 11 in general and administrative. In the quarter ended June 30, 2003, the Company recorded a restructuring charge of approximately $0.7 million, consisting mainly of workforce reduction costs.

9

In the quarter ended September 30, 2003, the Company recorded an additional restructuring charge associated with this action of approximately $3.3 million, consisting of $1.1 million for workforce reduction, $1.7 million in future lease obligations for unused facilities and $0.5 million for capital equipment write-offs. In the quarter ended December 31, 2003, the Company recorded an additional restructuring charge of $0.1 million related to future lease obligations and employee severance benefits. The capital equipment write-offs and a majority of severance costs related to this restructuring were incurred by the end of 2003, and the Company anticipates that all other costs related to this restructuring, consisting principally of lease obligations on unused space, will be paid by the end of 2005.

     The following summarizes the changes to the June 2003 restructuring reserves for the three months ended March 31, 2004:

     In January 2004, the Company announced a limited reorganization of its internal business operations. This action, a continuation of the Company’s emphasis on expense management, resulted in the termination of ten individuals in the Company’s corporate office in Burlington, Massachusetts. The Company recorded a restructuring charge of approximately $0.5 million relating to employee severance and termination benefits.

9. PROVISION FOR (BENEFIT FROM) INCOME TAXES

     The income tax provision for the three months ended March 31, 2004 reflects a net benefit of $0.8 million which consists of an income tax benefit at an annual effective tax rate of 32.0%, as well as a $0.3 million tax benefit related to the recognition of prior years research and development tax credits. The 32.0% rate differs from the statutory rate of 34.0% due to a decrease in estimated pre-tax profit. The income tax provision for the three months ended March 31, 2003 reflects a net benefit of $0.1 million which consists of an income tax benefit at an annual effective tax rate of 20%.

10. RECENT ACCOUNTING PRONOUNCEMENTS

     In January 2003, the FASB issued Interpretation No. 46, “Consolidation of Variable Interest Entities, an Interpretation of Accounting Research Bulletin No. 51, Consolidated Financial Statements” (FIN 46). FIN 46 establishes accounting guidance for consolidation of variable interest entities (VIEs) that function to support the activities of the primary beneficiary. FIN 46 applies to any business enterprise, both public and private, that has a controlling interest, contractual relationship or other business relationship with a VIE.

10

     In December 2003, the FASB published a revision to FIN 46 to clarify some of the provisions and to exempt certain entities from its requirements. Under the new guidance, special effective date provisions apply to enterprises that have fully or partially applied FIN 46 prior to issuance of the revised interpretation. Otherwise, application of Interpretation 46R (FIN 46R) is required in financial statements of public entities that have interests in structures that are commonly referred to as special-purpose entities (SPEs) for periods ending after December 15, 2003. Application by public entities, other than business issuers, for all other types of VIEs other than SPEs, is required in financial statements for periods ending after March 15, 2004. The Company does not have any investments in or contractual relationships or other business relationships with any VIE and therefore the adoption did not have any impact on the Company’s consolidated financial position, results of operations or cash flows.

Critical Accounting Policies and Estimates

     Lightbridge has identified and discussed certain critical accounting policies and estimates in its Annual Report on Form 10-K for the year ended December 31, 2003. The Company did not modify its critical accounting policies during the quarter ended March 31, 2004. Those policies and estimates have been applied in the preparation of the Company’s financial statements included in this Quarterly Report on Form 10-Q. In applying its critical accounting policies, the Company increased the annual estimated effective tax rate to 32% in the quarter ended March 31, 2004.

Overview

     Lightbridge develops, markets and supports a suite of products and services for communications providers and online businesses that supports the customer lifecycle, including customer qualification and acquisition, risk management, electronic payment processing, prepaid billing, mobile data management and authentication services. Lightbridge’s software-based solutions are delivered primarily on an outsourced or service bureau basis. These outsourced or service bureau solutions together with the Company’s TeleServices offerings comprise the Company’s transaction business. Lightbridge’s transaction-based solutions provide multiple, remote, systems access for workflow management, along with centrally managed client-specified business policies, and links to client and third-party systems. Lightbridge also derives revenues from software licensing, consulting and maintenance services, and hardware sales. While its solutions historically have been delivered primarily to wireless carriers, Lightbridge also provides solutions to wireline carriers and non-carrier clients.

     In June 2002, the Company announced that it was reducing its workforce by seven percent and consolidating its Waltham, Massachusetts call center operations into its Lynn, Massachusetts and Broomfield, Colorado facilities by the end of 2002. In March 2003, the Company announced that it would be streamlining its exiting Broomfield, Colorado call center operations into its Lynn, Massachusetts facility and a smaller facility in Broomfield, Colorado by the end of May 2003. In June 2003, the Company announced it would be closing its Irvine, California facility and transferring certain employment positions to its Broomfield, Colorado facility and reducing its headcount by an estimated 70 employees.

     In December 2003, the Company entered into an agreement to lease approximately 80,000 square feet in a single building in Burlington, Massachusetts for its new principal administrative, sales, consulting, marketing and product development facility. In February 2004, the Company announced the planned expansion of its call center operations to Liverpool, Nova Scotia, Canada. The Company’s Nova Scotia facility became operational on April 15, 2004.

      In January 2004, the Company announced a limited reorganization of its internal business operations. This action, a continuation of the Company’s emphasis on expense management, resulted in the termination of ten individuals in the Company’s corporate office in Burlington, Massachusetts. The Company recorded a restructuring charge of approximately $0.5 million relating to severance and termination benefits.

     On March 31, 2004, the Company acquired all of the outstanding stock of Authorize.Net for $82 million in cash from InfoSpace Inc. and expects to incur approximately $2.1 million in acquisition related transaction costs. The purchase price paid by the Company in the Authorize.Net acquisition is subject to adjustment based on the final determination of working capital required at closing as set forth in the stock sale agreement. Authorize.Net is a provider of payment solutions for online customer transactions. The Authorize.Net payment gateway provides credit card and electronic check solutions to companies that process orders for goods and services over the Internet. Authorize.Net connects small and medium sized businesses to large credit card processors and banking organizations, allowing those businesses to accept electronic payments.

     Lightbridge’s transaction services revenues are derived primarily from the processing of applications for qualification of subscribers for telecommunications services and the activation of service for those subscribers. Over time, the Company has expanded its offerings from credit evaluation services to include screening for subscriber fraud, evaluating carriers’ existing accounts, interfacing with carrier and third-party systems and providing call center services. The Company also offers transaction services to screen and authenticate the identity of users engaged in online transactions. Transaction services are provided through contracts with carriers and others, which specify the services to be utilized and the markets to be served. The Company’s clients are charged for these services on a per transaction basis. Pricing varies depending primarily on the volume and type of transactions, the number and type of other products and services selected for integration with the services and the term of the contract under which services are provided. The volume of processed transactions varies depending on seasonal and retail trends, the success of the carriers and others utilizing the Company’s services in attracting subscribers and the markets served by the Company’s clients. Transaction revenues are recognized in the period in which the services are performed.

     The Company’s software licensing revenues consist of revenues attributable to the licensing of the Company’s CAS Application Modules, Risk Management, Prepaid Billing and Mobile Data Management software. Lightbridge’s CAS modules are designed to assist customers in interfacing with the Company’s transaction processing systems as well as to perform other point-of-sale and channel functionality. In the quarter ended March 31, 2004, the Company determined that it would no longer actively market or sell its Retail Management System (RMS). The Risk Management products are designed to assist carriers in monitoring subscriber accounts to identify activity that may indicate fraud. The Prepaid Billing system allows carriers to market and manage prepaid wireless services to customers. The Mobile Data Management solutions provide wireless carriers a platform for the development and management of data content and applications. The Company’s software products are licensed as packaged software products and each product generally requires incidental customization or integration with other products and systems to varying degrees. Software licensing revenues are recognized when persuasive evidence of an arrangement exists, delivery of the product has been made, and a fixed fee and collectiblity have been determined.

13

     The Company’s consulting and services revenues historically have been derived principally from providing solution development and deployment services and business advisory consulting in the areas of customer acquisition and retention, authentication, prepay billing and risk management. The majority of consulting and services engagements are performed on a time and materials basis and revenues from these engagements are generally recognized as the services are performed. When the Company performs work under a fixed fee arrangement, revenues are generally recognized as services are performed. Revenues from software maintenance contracts are recognized ratably over the term of the maintenance agreement and are reported as consulting and services revenues.

     The Company’s hardware revenues historically have been derived in connection with sales of its PrePay and PhonePrint products. Revenue from hardware is recognized upon shipment, unless testing, integration or other services are required, in which case it is recognized upon commissioning and acceptance of the product. Revenue from hardware sold in conjunction with software is deferred until the software revenue is recognized. The Company does not expect hardware revenues to be a significant component of revenue in the future.

     In the quarter ended March 31, 2004, four clients accounted for 25%, 20%, 12% and 7% of the Company’s total revenues. In the quarter ended March 31, 2003, four clients accounted for 28%, 23%, 16% and 12% of the Company’s total revenues. A loss of one or more of these major clients, a bankruptcy or period of financial difficulty of one or more of these clients, a decrease in orders by one or more of these clients or a change in the combination of products and services obtained from the Company by one or more of these clients would adversely affect Lightbridge’s revenues, margins and net income.

14

Results Of Operations

     The following table sets forth, for the periods indicated, certain financial data as a percentage of total revenues:

15

Quarter Ended March 31, 2004 Compared with Quarter Ended March 31, 2003.

     Revenues. Revenues and certain revenue comparisons for the quarters ended March 31, 2004 and 2003 were as follows:

     The increase in transaction revenues of $0.8 million was due to increased client subscriber activations. A change in the combination of services provided by Lightbridge’s TeleServices call centers mitigated against lower transaction fees charged to certain clients as a result of competitive pricing pressures.

     The Company’s transaction revenues will continue to reflect the industry’s rate of growth of new subscribers as well as the rate of switching among carriers by subscribers (subscriber churn). While Lightbridge experienced an increase in transactions revenues in the quarter ended March 31, 2004 as compared to the quarter ended March 31, 2003, it is unable to forecast whether this trend will continue during the remainder of 2004. Lightbridge believes that it may experience changes in the demand for its TeleServices business and changes in the combination of services acquired by clients and competitive pricing pressures that could affect transaction revenues in the remainder of 2004.

     The increase in software licensing revenues of $0.9 million resulted from the recording of two new software contracts in the first quarter of 2004. The Company expects the level of capital spending by carriers to continue to affect the sales of Lightbridge software products during the remainder of 2004.

     The decrease in consulting and services revenues of $0.7 million for the quarter ended March 31, 2004 was principally due to a decline in maintenance fees for the PrePay product, resulting from certain maintenance pricing modifications to the Company’s agreement with Ericsson AB. The Company expects that the level of software sales will continue to affect consulting and services revenues during the remainder of 2004.

     There was a slight increase in hardware revenues of $0.2 million for the quarter ended March 31, 2004. The Company does not expect hardware revenues to be a significant component of revenue in 2004.

     Cost of Revenues. Cost of revenues consists primarily of personnel costs, costs of resold third party hardware, software and services, costs of maintaining systems and networks used in processing qualification and activation transactions (including depreciation and amortization of systems and networks) and amortization of capitalized software and acquired technology. In the future, cost of revenues may vary as a percentage of total revenues as a result of a number of factors, including changes in the volume of transactions processed, changes in the mix of transaction revenues between those from automated transaction processing and those from processing transactions through the Company’s TeleServices Group, changes in pricing to certain clients and changes in the mix of total revenues among transactions revenues, software licensing and maintenance revenues and consulting services revenues. Generally, cost of revenue from automated transaction processing tends to be lower than costs of revenue from processing transactions through the Company’s TeleServices Group.

16

     Cost of revenues and certain cost of revenues comparisons for the quarters ended March 31, 2004 and 2003 were as follows:

     Transaction cost of revenues increased by $1.1 million in the first quarter of 2004 from the first quarter of 2003. Spending in Lightbridge’s TeleServices call centers increased as a result of increased staffing and training costs due to increased call center volume. The transaction cost of revenues increase was also affected by a shift in the combination of services acquired by clients during the first quarter of 2004. Lightbridge believes that changes in the combination of services acquired by clients may continue to negatively affect transaction cost of revenues in the remainder of 2004.

     Software licensing cost of revenues increased by $0.5 million in the first quarter of 2004 from the first quarter of 2003. This increase reflects a referral fee paid to a partner for one of the software contracts completed during the first quarter of 2004, as well as an increase in software revenue costs. The Company does not expect to incur a similar fee on software contracts in the future.

     Consulting and services cost of revenues decreased by $0.7 million in the quarter ended March 31, 2004, and also decreased as a percentage of total revenues to 7.6% in the quarter ended March 31, 2004 from 10.2% in the quarter ended March 31, 2003. The decrease in consulting and services cost of revenue was attributable to a reduction in headcount associated with the June 2003 and January 2004 restructurings, and reduced use of contract labor.

     Hardware cost of revenues increased by $0.3 million and also increased as a percentage of total revenue to 3.0% in the quarter ended March 31, 2004 from 2.0% in the quarter ended March 31, 2003. This increase was attributable to the increase in hardware revenues, and competitive pricing pressures.

     The Company expects that fluctuations in gross profit may occur primarily because of a change in the mix of revenue generated from the Company’s four revenue components, particularly revenues from software licensing and consulting services, and also because of competitive pricing pressures.

17

     Operating Expenses. Operating expenses and certain operating expense comparisons for the quarters ended March 31, 2004 and 2003 were as follows:

     Development. Development expenses include software development costs, consisting primarily of personnel and outside technical service costs related to developing new products and services, enhancing existing products and services, and implementing and maintaining new and existing products and services. The decrease in the development expenses for the quarter ended March 31, 2004 was primarily due to cost savings associated with the June 2003 and January 2004 restructurings. Development expenses as a percentage of total revenues decreased for the quarter ended March 31, 2004 as a result of higher revenue levels. The Company expects development expenses to increase in the remainder of 2004 in connection with the further development of its existing products and services, the development of new products and services and the development expenses associated with Authorize.Net's business.

     Sales and Marketing. Sales and marketing expenses consist primarily of salaries, commissions and travel expenses of direct sales and marketing personnel, as well as costs associated with advertising, trade shows and conferences. The decrease for the quarter ended March 31, 2004 was primarily due to reduced spending on marketing programs. The Company expects that sales and marketing expenses to increase in the remainder of 2004 primarily due to the inclusion of such expenses associated with the Authorize.Net business.

     General and Administrative. General and administrative expenses consist principally of salaries of executive, finance, human resources and administrative personnel and fees for certain outside professional services. The slight increase in general and administrative costs for the quarter ended March 31, 2004 was primarily due to expenses incurred as a result of increased regulatory and compliance requirements. The Company expects general and administrative expenses to increase during the remainder of 2004 due to increased regulatory compliance requirements associated with operating as a public company, consumer credit and privacy regulations, the operation of Authorize.Net, and costs associated with the relocation of its headquarters facility.

     Purchased In-Process Research and Development (“IPR&D”). In connection with the Authorize.Net acquisition, the Company recorded a $0.7 million charge during the first quarter of 2004 for several IPR&D projects. The allocation of the Authorize.Net purchase price was based upon an independent appraisal of the estimated fair value of the assets acquired and the liabilities assumed.

18

     Interest Income. Interest income decreased to $0.4 million in the quarter ended March 31, 2004 from $0.5 million in the quarter ended March 31, 2003. This decrease was primarily due to a decline in interest rates.

     Provision For (Benefit From) Income Taxes. Lightbridge’s annual estimated effective tax rate was 32.0% (excluding the benefit from the utilization of prior year’s tax credits) for the quarter ended March 31, 2004 compared to 20% for the quarter ended March 31, 2003. Lightbridge anticipates that the rate for the full year 2004 will approximate 32%.

Restructurings

     In June 2002, the Company announced that it was reducing its workforce by seven percent and consolidating its Waltham, Massachusetts call center operations into its Lynn, Massachusetts and Broomfield, Colorado facilities by the end of 2002. The Company recorded a restructuring charge of approximately $3.6 million, consisting of $1.6 million for workforce reductions, $1.3 million for facilities reductions including lease obligations, utilities and security costs on unused space and $0.7 million for capital equipment write-offs associated with these measures. The restructuring plan resulted in the termination of 65 personnel as follows: 25 in product and service delivery, 22 in development, 11 in sales and marketing and seven in general and administrative. The capital equipment write-offs and a majority of severance costs related to this restructuring were incurred by the end of 2002, and the Company anticipates that all other costs relating to this restructuring, consisting principally of lease obligations on unused space, will be paid by the end of 2004.

19

     The following summarizes the changes to the June 2002 restructuring reserves for the three months ended March 31, 2004:

     In March 2003, the Company announced that it would be streamlining its existing Broomfield, Colorado call center operations into its Lynn, Massachusetts facility and a smaller facility in Broomfield, Colorado by the end of May 2003. In the quarter ended March 31, 2003, the Company recorded a restructuring charge of approximately $0.1 million for workforce reductions. In the quarter ended June 30, 2003, the Company recorded an additional restructuring charge associated with this action of approximately $1.0 million, consisting of approximately $0.6 million in future lease obligations for unused facilities and approximately $0.4 million for capital equipment write-offs. The capital equipment write-offs and a majority of severance costs related to this restructuring were incurred by the end of 2003, and the Company anticipates that all other costs relating to this restructuring, consisting principally of lease obligations on unused space, will be paid by the end of 2004.

     The following summarizes the changes to the March 2003 restructuring reserves for the three months ended March 31, 2004:

     In June 2003, the Company announced that it would be closing its Irvine, California facility and transferring certain employment positions to its Broomfield, Colorado facility and reducing its headcount by an estimated 70 employees as follows: 16 in product and service delivery, 30 in development, 13 in sales and marketing and 11 in general and administrative. In the quarter ended June 30, 2003, the Company recorded a restructuring charge of approximately $0.7 million, consisting mainly of workforce reduction costs. In the quarter ended September 30, 2003, the Company recorded an additional restructuring charge associated with this action of approximately $3.3 million, consisting of $1.1 million for workforce reduction, $1.7 million in future lease obligations for unused facilities and $0.5 million for capital equipment write-offs. In the quarter ended December 31, 2003, the Company recorded an additional restructuring charge of $0.1 million related to future lease obligations and employee severance benefits. The capital equipment write-offs and a majority of severance costs related to this restructuring were incurred by the end of 2003, and the Company anticipates that all other costs related to this restructuring, consisting principally of lease obligations on unused space, will be paid by the end of 2005.

20

     The following summarizes the changes to the June 2003 restructuring reserves for the three months ended March 31, 2004:

     In January 2004, the Company announced a limited reorganization of its internal business operations. This action, a continuation of the Company’s emphasis on expense management, resulted in the termination of ten individuals in the Company’s corporate office in Burlington, Massachusetts. The Company recorded a restructuring charge of approximately $0.5 million relating to employee severance and termination benefits.

Liquidity And Capital Resources

     As of March 31, 2004, Lightbridge had cash and cash equivalents and short-term investments of $55.5 million. Lightbridge’s working capital decreased to $54.0 million at March 31, 2004 from $137.7 million at December 31, 2003 due principally to the payment of the acquisition price of $82 million for the Authorize.Net business and related acquisition costs. The Company believes that its current cash balances will be sufficient to finance the Company’s operations and capital expenditures for the next twelve months. Thereafter, the adequacy of the Company’s cash balances will depend on a number of factors that are not readily foreseeable such as the impact of general market conditions on the Company’s operations, cash requirements related to the recent acquisition of Authorize.Net, additional acquisitions or investments, restructuring or obligations associated with the closure of products or facilities, and the sustained profitability of the Company’s operations.

     During the first three months of 2004, the Company generated cash flows from operating activities of $1.4 million and used $21.7 million and $0.5 million in investing and financing activities, respectively.

     The Company’s capital expenditures totaled $1.0 million for the quarter ended March 31, 2004. The capital expenditures during this period were principally associated with the Company’s service delivery infrastructure and computer equipment for software development activities. The Company leases its facilities and certain equipment under non-cancelable operating lease agreements that expire at various dates through January 2011.

     During the three months ended March 31, 2004, the Company used $0.8 million for the repurchase of the Company’s common stock under the stock repurchase program.

     On February 10, 2004, the Company entered into a lease agreement with the Region of Queens Municipality to lease 32,144 square feet of space in Liverpool, Nova Scotia, Canada. The lease runs through April 30, 2009, with an option to renew at the end of the current lease term. The lease also gives the Company the right to terminate upon the third anniversary thereof. The future minimum commitments under this lease are as follows:

     At March 31, 2004, the Company was holding funds in the amount of $6.4 million on behalf of merchants utilizing Authorize.Net’s eCheck services. The funds are included in cash and cash equivalents and funds due to merchants on the Company’s condensed consolidated balance sheet. Authorize.Net typically holds eCheck funds for approximately seven business days; the actual number of days depends on the contractual terms with each merchant. In addition, the Company currently has $0.6 million on deposit with the financial institution. The deposits are held to cover a deficit account balance that could occur if the amount of transactions returned or charged back exceeds the balance on deposit with the financial institutions. To date, the deposits have not been applied to offset a deficit balance, and management believes that the likelihood of incurring a deficit balance with the financial institutions due to the amount of transactions returned or charged back is remote. The deposit will be held continuously for as long as Authorize.Net utilizes the ACH processing services of the financial institution, and the amount of the deposit may increase as processing volume increases.

     At March 31, 2004, the Company held funds in the amount of $0.7 million for and on behalf of merchants processing credit card and ACH transactions using the Integrated Payment Solution (IPS) product. The funds are included in cash and cash equivalents and funds due to merchants on the Company’s condensed consolidated balance sheet. Credit card funds are typically held for approximately two business days; ACH funds are held for approximately four business days, according to the specifications of the product and the contract between Authorize.Net and the financial institution through which the transactions are processed.

     At March 31, 2004, the Company had two outstanding letters of credit, each in the amount of $1.0 million, expiring in May 2004 and January 2005.

21

     On January 14, 2003, the Company entered into a foreign exchange agreement, effective April 2003, with a bank for the purchase of one currency in exchange for the sale of another currency. This agreement is secured by $3.0 million held by the bank. To date, there have been no transactions under this agreement.

Inflation

     Although certain of Lightbridge’s expenses increase with general inflation in the economy, inflation has not had a material impact on Lightbridge’s financial results to date.

Recent Accounting Pronouncements

     In January 2003, the FASB issued Interpretation No. 46, “Consolidation of Variable Interest Entities, an Interpretation of Accounting Research Bulletin No. 51, Consolidated Financial Statements” (FIN 46). FIN 46 establishes accounting guidance for consolidation of variable interest entities (VIEs) that function to support the activities of the primary beneficiary. FIN 46 applies to any business enterprise, both public and private, that has a controlling interest, contractual relationship or other business relationship with a VIE.

     In December 2003, the FASB published a revision to FIN 46 to clarify some of the provisions and to exempt certain entities from its requirements. Under the new guidance, special effective date provisions apply to enterprises that have fully or partially applied FIN 46 prior to issuance of the revised interpretation. Otherwise, application of Interpretation 46R (FIN 46R) is required in financial statements of public entities that have interests in structures that are commonly referred to as special-purpose entities (SPEs) for periods ending after December 15, 2003. Application by public entities, other than business issuers, for all other types of VIEs other than SPEs, is required in financial statements for periods ending after March 15, 2004. The Company does not have any investments in or contractual relationships or other business relationships with any VIE and therefore the adoption did not have any impact on the Company’s consolidated financial position, results of operations or cash flows.

Risk Factors

If One or More of Our Major Clients Stops Using Our Products or Services or Changes the Combination of Products and Services It Uses, Our Operating Results Would Suffer Significantly.

     Our revenues are concentrated among a few major clients. Our 10 largest clients accounted for approximately 91% of our total revenues in 2003, and we expect that most of our revenues will continue to come from a relatively small number of clients for the foreseeable future. Consequently, our revenues, margins and net income may fluctuate significantly from quarter to quarter based on the actions of a single significant client. A client may take actions that significantly affect us for reasons that we cannot necessarily anticipate or control, such as reasons related to the client’s financial condition, changes in the client’s business strategy or operations, the introduction of alternative competing products or services, or as the result of the perceived quality or cost-effectiveness of our products or services. Our services agreements with Sprint Spectrum L.P. (“Sprint”), and Nextel Operations, Inc. (“Nextel”) expire on December 31, 2006, and our service agreement with AT&T Wireless Services, Inc. (“AT&T”) expires on December 31, 2004. It is possible that Sprint, Nextel and/or AT&T could elect not to renew their agreements, to reduce the volume of products and services they purchase from us or to request significant changes to the pricing or other terms in any renewal agreement. In February 2004, Cingular Wireless announced an agreement to acquire AT&T. Cingular Wireless is not presently a client of Lightbridge. We are unable to predict the effect of the acquisition on our relationship with AT&T. The loss of AT&T or any of our other major clients would cause sales to fall below expectations and materially reduce our revenues, margins and net income.

Certain of Our Revenues Are Uncertain Because Our Clients May Reduce the Amounts of or Change the Combination of Our Products or Services They Purchase.

     Most of our communications client contracts extend for terms of between one and three years. During the terms of these contracts, our communications clients typically may elect to purchase any of several different combinations of products and services. The revenue that we receive for processing a transaction for such a client may vary significantly depending on the particular products and services used to process the transaction. In particular, transactions handled through our TeleServices Group generally result in significantly higher revenue to us than transactions that are submitted and processed electronically. Therefore, our revenues from a particular client may decline if the client changes the combination of products and services it purchases from us.

     To the extent our client contracts contain minimum purchase or payment requirements, these minimums are typically at levels significantly below actual or historical purchase or payment levels. Therefore, our current clients may not continue to utilize our products or services at levels similar to previous years or at all, and may not generate significant revenues in future periods. If any of our major clients significantly reduces or changes the combination of products or services it purchases from us for any reason, our business would be seriously damaged.

Our Revenues Are Concentrated in the Wireless Telecommunications Industry, Which Is Experiencing Declining Growth Rates, Consolidation and Increasing Pressure to Control Costs.

     We currently derive most of our revenues from companies in the wireless telecommunications industry, and we expect that wireless telecommunications companies will continue to account for a substantial majority of our revenues for the foreseeable future. In recent years, the growth rate of the domestic wireless industry has slowed. In addition, consolidation has affected the number of carriers to whom our products and services can be marketed and sold, and competition among wireless carriers has continued to increase, resulting in heightened efforts by carriers to control costs.

23

Many of our carrier clients have sought, and may in the future seek, pricing concessions when they renew their service agreements with us, which could affect our revenues and profitability. In addition, certain of our carrier clients have sought bankruptcy protection in the past year, and we believe it is likely that additional clients may file for bankruptcy protection if current industry conditions continue. Bankruptcy filings by our clients or former clients such as WorldCom Wireless Incorporated (“WorldCom”) may prevent us from collecting some or all of the amounts owing to us at the time of filing, may require us to return some or all of any payments received by us within 90 days prior to a bankruptcy filing which could be significant in amount as is the case with WorldCom and may also result in the termination of our service agreements. As a result of the foregoing conditions, our success depends on a number of factors:

•		our ability to maintain our profit margins on sales of products and services to companies in the wireless telecommunications industry;
•		the financial condition of our clients and their continuing ability to pay us for services and products;
•		our ability to develop and market new or enhanced products and services to new and existing clients;
•		continued growth of the domestic wireless telecommunications markets;
•		the number of carriers seeking to implement prepaid billing services; and
•		our ability to increase sales of our products and services internationally.

Our Future Revenues May Be Uncertain Because of Reliance on Third Parties for Marketing and Distribution.

     The PrePay billing system is currently marketed primarily through a distribution agreement with Ericsson, which is the source of substantially all of our revenue derived from the PrePay billing system in recent years. That agreement may be terminated by either party on 180 days, notice to the other. We have also entered into a business alliance with VeriSign, Inc. (“VeriSign”) to assist us in penetrating the online transaction market. In addition, Authorize.Net distributes its service offerings primarily through third party resellers. In 2003, Authorize.Net’s revenues were derived predominantly through relationships with distribution partners.

     We intend to continue to market and distribute our current and future products and services through existing and other relationships both in and outside of the United States. There are no minimum purchase obligations applicable to any existing distributor or other sales and marketing partners and we do not expect to have any guarantees of continuing orders. Failure by our existing and future distributors or other sales and marketing partners to generate significant revenues or our failure to establish additional distribution or sales and marketing alliances could have a material adverse effect on our business, operating results and financial condition.

     In addition, distributors and other sales and marketing partners may become our competitors with respect to the products they distribute either by developing a competitive product themselves or by distributing a competitive offering. For example, Ericsson may evaluate and seek to distribute or acquire alternative vendors’ prepaid products that compete with PrePay, and VeriSign may elect to market or acquire alternative fraud and identity verification products. Competition from existing and future distributors or other sales and marketing partners could significantly harm sales of our products.

We Have Made and May Continue to Make Acquisitions, Which Involve Risks.

     We acquired Coral Systems, Inc. in November of 1997, Corsair Communications, Inc. (“Corsair”) in February of 2001, the assets of Altawave in February of 2002 and Authorize. Net in March of 2004. We may also make additional acquisitions in the future if we identify companies, technologies or assets that appear to complement our business. Acquisitions involve risks that could cause the actual results of any acquisitions we make to differ from our expectations. For example:

•		We may be unable to integrate Authorize.Net or other acquired businesses successfully and to realize anticipated economic, operational and other benefits in a timely manner. Integration of Authorize.Net could prove especially difficult because it operates in a market in which we have limited expertise and because its operations are geographically remote from our existing facilities. The need to retain existing clients and employees of an acquired company and to integrate differing corporate cultures can also present significant risks. If we are unable to successfully integrate Authorize.Net or other acquired businesses, we may incur substantial costs and delays or other operational, technical or financial problems.
•		Our acquisition of Authorize.Net significantly reduced our available cash and liquidity. In other future acquisitions, we may issue equity securities that could be dilutive to our shareholders or we may use our remaining cash, which may have an adverse effect on our liquidity. We also may incur additional debt and amortization expense related to intangible assets as a result of acquisitions. This additional debt and amortization expense, as well as the potential impairment of any purchased goodwill, may materially and adversely affect our business and operating results. We may also be required to make continuing investments in acquired products or technologies to bring them to market, which may negatively affect our cash flows and net income. In addition, we may assume contingent liabilities that may be difficult to estimate.

24

•

Acquisitions may divert management’s attention from our existing business and may damage our relationships with our key clients and employees.

The Success of Our Growth Strategy Is Dependent on Our Ability to Expand into New Markets.

     In order to achieve growth in our business, we are seeking to expand our business into new markets, including the online transaction market and the wireless data market. If we are not able to expand successfully into new markets, our financial results and future prospects may be harmed. Our ability to enter new markets depends on a number of factors, including:

•		growth in the online transaction market;
•		our ability to provide products and services to address the needs of those markets; and
•		competition in those markets.

If We Do Not Continue to Enhance Our Existing Products and Services, and Develop or Acquire New Ones, We Will Not Be Able to Compete Effectively.

     The industries in which we do business or intend to do business have been changing rapidly as a result of increasing competition, technological advances, regulatory changes and evolving industry practices and standards, and we expect these changes will continue. Current and potential clients have also experienced significant changes as the result of consolidation among existing industry participants and economic conditions. In addition, the business practices and technical requirements of our clients are subject to changes that may require modifications to our products and services. In order to remain competitive and successfully address the evolving needs of our clients, we must commit a significant portion of our resources to:

•		identify and anticipate emerging technological and market trends affecting our core wireless business as well as the online market;
•		enhance our current products and services in order to increase their cost-effectiveness to clients that are seeking to control costs and to meet regulatory requirements;
•		develop or acquire new products and services that meet emerging client needs, such as services to allow companies to authenticate the identity of consumers engaged in online transactions and products and services for the online market;
•		modify our products and services in response to changing business practices and technical requirements of our clients, as well as to new regulatory requirements, such as local number portability;
•		integrate our current and future products; and
•		create and maintain interfaces to changing client and third party systems.

     We must achieve these goals in a timely and cost-effective manner and successfully market our new and enhanced products and services to clients. In the past, we have experienced errors or delays in developing new products and in modifying or enhancing existing products. If we are unable to expand or appropriately enhance or modify our products and services quickly and efficiently, our business and operating results will be adversely affected.

25

We and Our Clients Must Comply with Complex and Changing Laws and Regulations.

     Government regulation influences our activities and the activities of our current and prospective clients, as well as our clients’ expectations and needs in relation to our products and services. Businesses that handle consumers’ funds, such as our Authorize.Net business, are subject to numerous regulations, including those related to banking, credit cards, escrow, fair credit reporting, privacy of financial records and others. State money transmitter regulations and federal anti-money laundering and money services business regulations can also apply under some circumstances. The application of many of these laws with regard to electronic commerce is currently unclear. If applied to us, these rules and regulations could require us to change the way we do business in a way that increases costs or makes our business more complex. In addition, violation of some statues may result in severe penalties or restrictions on our ability to engage in e-commerce, which could have a material adverse effect on our business.

     Our clients also include telecommunications companies that, to the extent that they extend consumer credit, may be subject to federal and state regulations. In making credit evaluations of consumers, performing fraud screening or user authentication, our clients are subject to requirements of federal law, including the Equal Credit Opportunity Act (“ECOA”), the Fair Credit Reporting Act (“FCRA”) and the Gramm-Leach-Bliley Act (“GLBA”) and regulations thereunder, as well as state laws which impose a variety of additional requirements. Privacy legislation may also affect the nature and extent of the products or services that we can provide to clients as well as our ability to collect, monitor and disseminate information subject to privacy protection. Although most of the products and services we provide to the telecommunications industry, other than our ProFile service, are not directly subject to these requirements, we must take these extensive and evolving requirements into account in order to meet our clients’ needs. In some cases, consumer credit laws require our clients to notify consumers of credit decisions made in connection with their applications for telecommunications services, and we have contracted with some of our clients, including Sprint, AT&T, Nextel, Western Wireless Corporation and Dobson Communications, Inc., to provide such notices on their behalf. Our software has in the past contained, and could in the future contain, undetected errors affecting compliance by our clients with one or more of these legal requirements. Failure to properly implement these requirements in our products and services in a timely, cost-effective and accurate manner could result in liability, either directly or as indemnitor of our clients, damage to our reputation and relationships with clients and a loss of business.

     Consumer protection laws in the areas of privacy, credit and financial transactions have been evolving rapidly at the state, federal and international levels. As the electronic transmission, processing and storage of financial information regarding consumers continues to grow and develop, it is likely that more stringent consumer protection laws may impose additional burdens on companies involved in such transactions. Uncertainty and new laws and regulations, as well as the application of existing laws to e-commerce, could limit our ability to operate in our markets, expose us to compliance costs and substantial liability and result in costly and time consuming litigation.

Changes to Credit Card Association Rules or Practices Could Adversely Impact Our Authorize.Net Business.

     Our Authorize.Net credit card payment gateway does not directly access the Visa and MasterCard credit card associations. As a result, we must rely on banks and their service providers to process our transactions. We must comply with the operating rules of the credit card associations. The associations’ member banks set these rules, and the associations interpret the rules. Some of those member banks compete with Authorize.Net. Visa, MasterCard, American Express or Discover could adopt new operating rules or interpretations of existing rules which we might find difficult or even impossible to comply with, in which case we could lose our ability to give customers the option of using credit cards to fund their payments. If we were unable to process credit card transactions, our Authorize.Net business would be materially and adversely affected.

We Could be Subject to Liability as a Result of Security Breaches or Fraudulent or Illegal Use of Our Services.

     Because some of our activities involve the storage and transmission of confidential personal or proprietary information, such as credit card numbers, security breaches and fraud schemes could damage our reputation and expose us to a risk of loss or litigation and possible liability. Our payment gateway services may be susceptible to credit card and other payment fraud schemes, including unauthorized use of credit cards or bank accounts, identity theft or merchant fraud. We expect that technically sophisticated criminals will continue to attempt to circumvent our anti-fraud systems. If such fraud schemes become widespread or otherwise cause merchants to lose confidence in our services in particular, or in Internet systems generally, our business could suffer.

     In addition, the large volume of payments that we handle for our clients makes us vulnerable to employee fraud or other internal security breaches. We cannot assure you that any internal control systems will prevent material losses from employee fraud. Further, we may be required to expend significant capital and other resources to protect against security breaches and fraud to address any problems they may cause.

     Our payment system may also be susceptible to potentially illegal or improper uses. These uses may include illegal online gambling, fraudulent sales of goods or services, illicit sales of prescription medications or controlled substances, software and other intellectual property piracy, money laundering, bank fraud, child pornography trafficking, prohibited sales of alcoholic beverages and tobacco products and online securities fraud. Despite measures we have taken to detect and lessen the risk of this kind of conduct, we cannot assure you that these measures will succeed. In addition, regulations under the USA Patriot Act of 2001 may require us to revise the procedures we use to comply with the various anti-money laundering and financial services laws. Our business could suffer if clients use our system for illegal or improper purposes or if the costs of complying with regulatory requirements increase significantly.

Our Reliance on Suppliers and Vendors Could Adversely Affect Our Ability to Provide Our Services and Products to Our Clients on a Timely and Cost-Efficient Basis.

     We rely to a substantial extent on third parties to provide some of our equipment, software, data, systems and services. In some circumstances, we rely on a single supplier or limited group of suppliers. For example, our Authorize.Net business requires the services of third-party payment processors. If any of these processors cease to allow us to access their processing platforms, our ability to process credit card payments would be severely impacted. In addition, we depend on our Originating Depository Financial Institution (“ODFI”) partner to process Automated Clearing House transactions, and our ability to process these transactions would be severely impacted if we were to lose our ODFI partner for any reason.

     Our reliance on outside vendors and service providers also subjects us to other risks, including a potential inability to obtain an adequate supply of required components and reduced control over quality, pricing and timing of delivery of components. For example, in order to provide our credit verification service, we need access to third-party credit information databases provided to us by outside vendors. Similarly, delivery of our activation services often requires the availability and performance of billing systems which are also supplied by outside vendors. If for any reason we were unable to access these databases or billing systems, our ability to process credit verification transactions could be impaired.

     In addition, our business is materially dependent on services provided by various telecommunications providers. A significant interruption in telecommunications services could seriously harm our business.

     From time to time, we must also rely upon third parties to develop and introduce components and products to enable us, in turn, to develop new products and product enhancements on a timely and cost-effective basis. In particular, we must rely on the development efforts of third-party wireless infrastructure providers in order to allow our PrePay product to integrate with both existing and future generations of the infrastructure equipment. We may not be able to obtain access, in a timely manner, to third-party products and development services necessary to enable us to develop and introduce new and enhanced products. We may not be able to obtain third-party products and development services on commercially reasonable terms and we may not be able to replace third-party products in the event such products become unavailable, obsolete or incompatible with future versions of our products.

26

Our Business May be Harmed by Errors in Our Software.

     The software that we develop and license to clients, and that we also use in providing our transaction processing and call center services, is extremely complex and contains hundreds of thousands of lines of computer code. Large, complex software systems such as ours are susceptible to errors. The difficulty of preventing and detecting errors in our software is compounded by the fact that we maintain multiple versions of our systems to meet the differing requirements of our major clients, and must implement frequent modifications to these systems in response to these clients’ evolving business policies and technical requirements. Our software design, development and testing processes are not always adequate to detect errors in our software prior to its release or commercial use. As a result, we have from time to time discovered, and may likely in the future discover, errors in software that we have put into commercial use for our clients, including some of our largest clients. Because of the complexity of our systems and the large volume of transactions they process on a daily basis, we sometimes have not detected software errors until after they have affected a significant number of transactions. Software errors can have the effect of causing clients that utilize our products and services to fail to comply with their intended credit or business policies, or to fail to comply with legal requirements, such as those under the ECOA, FCRA, or GLBA. Such errors, particularly if they affect a major client, can harm our business in several ways, including the following:

•		we may suffer a loss of revenue if, due to software errors, we are temporarily unable to provide products or services to our clients;
•		we may not be paid for the products or services provided to a client that contain errors, or we may be liable for losses or damages sustained by a client or its subscribers as a result of such errors;
•		we may incur additional unexpected expenses to correct errors in our software, or to fund product development projects that we may undertake to minimize the occurrences of such errors in the future;
•		we may damage our relationships with clients or suffer a loss of reputation within our industry;
•		we may become subject to litigation or regulatory scrutiny; and
•		our clients may terminate or fail to renew their agreements with us or reduce the products and services they purchase from us.

     Our errors and omissions insurance may not adequately compensate us for losses that may occur due to software errors. It is also possible that such insurance might cease to be available to us on commercially reasonable terms or at all.

Our Initiatives to Improve Our Software Design and Development Processes May Not Be Successful.

     The development of our core products has, in some cases, extended over a period of more than ten years. This incremental development process has resulted in a system which is extremely complex. Systems of the size and complexity of ours are inherently difficult to modify and maintain. Beginning in 2001, we began the process of rebuilding portions of our core products in Java, replacing the proprietary three-tiered software architecture historically employed in our products with a new architecture using a middleware layer and a standard database across all products. We expect that this architecture, which relies on component-based development and reusable frameworks, will accelerate our product development process and make it easier to maintain our software systems.

27

We are also evaluating changes in our product development, testing and control processes to improve the accuracy and timeliness of modifications that we make to our software, including the frequent modifications that we must make in response to changes in the business policies and technical requirements of our clients. We believe that our initiatives to implement a new product architecture and to improve our product development, test and control processes will be important to our future competitive position and success. If we are not successful in carrying out these initiatives on a timely basis or in a manner that is acceptable to our clients, our business and future prospects could be harmed.

Our Success Is Dependent in Part on PrePay, Which May Not Achieve Market Penetration.

     Our future operating results will depend to a significant extent on the demand for and market penetration of PrePay, our prepaid metered billing system. To date, only a small number of wireless carriers, almost all of them outside the U.S., have deployed PrePay, and the rate of adoption of the PrePay system will need to increase significantly in order to achieve our revenue targets. PrePay has been sold predominantly by Ericsson. Ericsson, from time to time, may evaluate and seek to distribute or acquire alternative vendors’ prepaid product offerings. Any change in the terms of our distribution arrangements with Ericsson or Ericsson’s desire to discontinue our relationship would drastically affect sales of PrePay. Although our own sales force also sells PrePay, it has not yet generated significant PrePay sales. We cannot ensure that sales of the PrePay system will increase or that PrePay will gain market penetration. If PrePay does not gain market penetration our future operating results would be adversely affected.

If We Are Unable to Acquire Complementary Businesses, Our Future Growth Will Be Limited.

     A key element of our growth strategy is to acquire businesses, technologies or products that expand and complement our business. We believe acquisitions are necessary for us to continue to grow at a desirable rate, and we will continue to evaluate possible acquisition opportunities in the future. Even if we are able to identify suitable companies or businesses to buy, we may not be able to purchase any of these companies at favorable prices, or at all, for any number of reasons. If we are unable to make acquisitions, we may not be able to meet or exceed our historical levels of growth and earnings.

We May Not Be Able to Successfully Manage Operational Changes.

     Over the last several years, our operations have experienced rapid growth in some areas and significant restructurings and cutbacks in others. These changes have created significant demands on our executive, operational, development and financial personnel and other resources. If we achieve future growth in our business, or if we are forced to make additional restructurings, we may further strain our management, financial and other resources. Our future operating results will depend on the ability of our officers and key employees to manage changing business conditions and to continue to improve our operational and financial controls and reporting systems. We cannot ensure that we will be able to successfully manage the future changes in our business.

28

Our Quarterly Operating Results May Fluctuate.

     Our operating results are difficult to predict and may fluctuate significantly from quarter to quarter. If our operating results fall below the expectations of investors or public market analysts, the price of our common stock could fall dramatically. Our common stock price could also fall dramatically if investors or public market analysts reduce their estimates of our future quarterly operating results, whether as a result of information we disclose, or based on industry, market or economic trends, or other factors.

     Our revenues are difficult to forecast for a number of reasons:

•		Seasonal and retail trends affect our transaction services revenues, which historically have represented the majority of our total revenues, and may affect demand for our other products and services. As a result, our revenues can fluctuate. For example, our revenues generally have been highest in the fourth quarter of each calendar year, particularly in the holiday shopping season between Thanksgiving and Christmas. In addition, marketing initiatives undertaken by our clients or their competitors may significantly affect the number of transactions we process.
•		The sales process for our products and services is lengthy, sometimes exceeding twenty-four months. The length of the sales process makes our revenues difficult to predict. The delay of one or more large orders, particularly orders for software, which typically result in a substantial amount of non-recurring revenue, could cause our quarterly revenues to fall substantially below expectations.
•		We ship our software products within a short period after receipt of an order, and we usually do not have a material backlog of unfilled orders of software products. Consequently, our revenues from software licenses in any quarter depend substantially on the orders booked and shipped in that quarter. As a result, a delay in the consummation of a license agreement may cause our revenues to fall below expectations for that quarter.
•		Our consulting services revenues can fluctuate based on the timing of product sales and projects we perform for our clients. Many of our consulting engagements are of a limited duration, so it can be difficult for us to forecast consulting services revenues or staffing requirements accurately more than a few months in advance.

     Most of our expenses, particularly employee compensation, are relatively fixed. As a result, even relatively small variations in the timing of our revenues may cause significant variations in our quarterly operating results and may result in quarterly losses.

29

     As a result of these factors, we believe that quarter-to-quarter comparisons of our results of operations are not necessarily meaningful. You should not rely on our quarterly results of operations to predict our future performance.

Our Foreign Sales and Operations Subject Us to Risks and Concerns Which Could Negatively Affect Our Business Overall.

     We expect our international revenues will continue to represent a significant portion of our total revenues. We also intend to further expand our sales efforts internationally. In addition to the risks generally associated with sales and operations in the U.S., sales to clients outside the U.S. and operations in foreign countries present us with many additional risks, including the following:

•		the imposition of financial and operational controls and regulatory restrictions by foreign governments;
•		the need to comply with a wide variety of complex U.S. and foreign import and export laws and treaties;
•		political and economic instability that may lead to reduced demand for our products and services;
•		changes in tariffs, taxes and other barriers that may reduce our ability to sell our solutions or may reduce the profitability of those solutions;
•		longer payment cycles and increased difficulties in collecting accounts receivable;
•		fluctuations in interest and currency exchange rates, which may reduce our earnings if we denominate arrangements with international clients in the currency of the country in which our products or services are provided, or with respect to arrangements with international clients that are U.S. dollar-denominated, which may make our systems less price-competitive;
•		changes in technology standards, such as interfaces between products, that are developed by foreign groups and may require additional development efforts on our part or change the buying behavior of some of our clients;
•		reduced protection for intellectual property rights in some countries;
•		difficulties in managing a global network of distributors or representatives and in staffing and managing foreign subsidiary operations;
•		costs and risks of localizing systems in foreign countries;
•		additional complications and expenses related to supporting products internationally; and
•		the possibility that our purchase agreements may be governed by foreign laws that differ significantly from U.S. laws, which may limit our ability to enforce our rights under these agreements.

30

We Face Significant Competition for a Limited Supply of Qualified Software Engineers and Consultants.

     Our business depends on the services of skilled software engineers who can develop, maintain and enhance our products and consultants who can undertake complex client projects. In general, only highly qualified, highly educated personnel have the training and skills necessary to perform these tasks successfully. In order to maintain the competitiveness of our products and to meet client requirements, we need to attract, motivate and retain a significant number of software engineers and consultants. Qualified personnel such as these are in short supply and we face significant competition for these employees, from not only our competitors but also clients and other enterprises. Other employers may offer software engineers and consultants significantly greater compensation and benefits or more attractive career paths than we are able to offer. Any failure on our part to hire, train and retain a sufficient number of qualified personnel would seriously damage our business.

Our Future Success Depends on the Continued Services of Key Executive Officers.

     Our future success will depend to a significant degree on the skills, experience and efforts of our executive officers, particularly Pamela D.A. Reeve, Chief Executive Officer. We do not have any employment contracts requiring Ms. Reeve or any of our other executive officers to continue their employment for any period of time, and we do not maintain key-person life insurance on any of our executive officers other than Ms. Reeve. If we lose the services of one or more of these persons, we may be unable to successfully manage our current business or implement our planned business objectives and our future operations may be adversely affected.

We Face Competition from a Broad and Increasing Range of Vendors.

     The market for products and services offered to communications providers and participants in online transactions is highly competitive and subject to rapid change. Each of these markets is fragmented, and a number of companies currently offer one or more products or services competitive with ours. We anticipate continued growth and the formation of new alliances in each of the markets in which we compete, which will result in the entrance of new competitors in the future. We face potential competition from several primary sources:

•		software vendors that provide one or more customer acquisition, customer relationship management and retention or risk management solutions, including ECtel Ltd., TSI Telecommunications Services Inc. (“TSI”), Fair, Isaac & Co. Inc., Magnum Software Systems, Inc., American Management Systems, Incorporated and SLP Infoware;
•		telecommunications equipment vendors that market software-based solutions to complement their hardware offerings, such as Hewlett-Packard Company and Ericsson;
•		service providers that offer customer acquisition, customer relationship management and retention, risk management or authentication services in connection with other services, including Choicepoint Inc., Visa U.S.A., Experian Information Solutions, Inc., Equifax, Inc., RiskWise, L.L.C., Trans Union, L.L.C., Schlumberger Sema plc and Amdocs Ltd;
•		information technology departments within larger carriers that have the ability to provide products and services that are competitive with those we offer;
•		information technology vendors that offer wireless and internet software applications such as Oracle Corporation, Microsoft Corporation and International Business Machine Corporation;

31

•		providers of online payment processing services, including VeriSign, CyberSource Corporation, PlugnPlay Technologies, Inc. and LinkPoint International, Inc.
•		consulting firms or systems integrators that may offer competitive services or the ability to develop customized solutions for customer acquisition and qualification, customer relationship management and retention or risk management, such as American Management Systems, Incorporated, Accenture Ltd., BearingPoint, Inc., PeopleSoft, Inc., Siebel Systems, Inc. and Cap Gemini Ernst & Young;
•		software vendors of prepaid wireless billing products, including Boston Communications Group, Inc., Intervoice, Inc., Comverse Technology, Inc., Glenayre Technologies, Inc., VeriSign Telecommunications Services, Telemac Cellular Corporation, Fair, Isaac & Co. Inc., ORGA Kartensysteme GmbH, Schlumberger Sema plc, Alcatel USA, Priority Call Management, Lucent Technologies, Inc., Hewlett-Packard Company (Tandem Division), Telcordia Technologies, Inc. and Sixbell;
•		a number of alternative technologies, including profilers, personal identification numbers and authentication, provided by companies such as Verizon Communications, Inc., Authentix Network Inc. and Fair, Isaac & Co., Inc.; and
•		vendors that provide products and services in the wireless data market, such as Bridgewater Systems Corporation, OracleMobile, a division of Oracle Corporation, 4thPass, Inc., TSI, Seven Networks, Inc. and Openwave Systems Inc.

     Because competitors can easily penetrate one or more of our markets, we anticipate additional competition from other established and new companies. In addition, competition may intensify as competitors establish cooperative relationships among themselves or alliances with others.

     Many of our current and potential competitors have significantly greater financial, marketing, technical and other competitive resources than we do. As a result, these competitors may be able to adapt more quickly to new or emerging technologies and changes in client requirements, or may be able to devote greater resources to the promotion and sale of their products and services. In addition, in order to meet client requirements, we must often work cooperatively with companies that are, in other circumstances, competitors. The need for us to work cooperatively with such companies may limit our ability to compete aggressively with those companies in other circumstances.

32

A Failure of, Error in or Damage to Our Computer and Telecommunications Systems Would Impair Our Ability to Conduct Transactions and Support Services and Harm Our Business Operations.

     We provide transaction services and support services using complex computer and telecommunications systems. Our business could be significantly harmed if these systems fail or suffer damage from fire, natural disaster, terrorism, power loss, telecommunications failure, unauthorized access by hackers, computer viruses or similar events. In addition, the growth of our client base, a significant increase in transaction volume or an expansion of our facilities may strain the capacity of our computers and telecommunications systems and lead to degradations in performance or system failure. Many of our agreements with carriers contain level of service commitments, which we might be unable to fulfill in the event of a natural disaster, an actual or threatened terrorist attack or a major system failure. Errors in our computer and telecommunications systems may adversely impact our ability to provide the products and services contracted for by our clients. We may need to expend significant capital or other resources to protect against or repair damage to our systems that occur as a result of malicious activities, natural disasters or human error, but these protections and repairs may not be completely effective. Our property and business interruption insurance and errors and omissions insurance might not be adequate to compensate us for any losses that may occur as the result of these types of damage. It is also possible that such insurance might cease to be available to us on commercially reasonable terms, or at all.

33

Our Success Depends in Part on Our Ability to Obtain Patents for, or Otherwise Protect, Our Proprietary Technologies.

     We rely on a combination of copyright, patent, trademark and trade secret laws, license and confidentiality agreements, and software security measures to protect our proprietary rights. Much of our know-how and other proprietary technology is not covered by patent or similar protection, and in many cases cannot be so protected. If we cannot obtain patent or other protection for our proprietary software and other proprietary intellectual property rights, other companies could more easily enter our markets and compete successfully against us.

     We have a limited number of patents in the U.S. and abroad, and have pending applications for additional patents, but we cannot be certain that any additional patents will be issued on those applications, that any of our current or future patents will protect our business or technology against competitors that develop similar technology or products or provide us with a competitive advantage, or that others will not claim rights in our patents or our proprietary technologies.

     Patents issued and patent applications filed relating to products used in the wireless telecommunications industry are numerous and it may be the case that current and potential competitors and other third parties have filed or will file applications for, or have received or will receive, patents or obtain additional proprietary rights relating to products used or proposed to be used by us. We may not be aware of all patents or patent applications that may materially affect our ability to make, use or sell any current or future products.

     The laws of some countries in which our products are licensed do not protect our products and intellectual property rights to the same extent as U.S. laws. We generally enter into non-disclosure agreements with our employees and clients and restrict access to, and distribution of, our proprietary information. Nevertheless, we may be unable to deter misappropriation of our proprietary information or detect unauthorized use of and take appropriate steps to enforce our intellectual property rights. Our competitors also may independently develop technologies that are substantially equivalent or superior to our technology.

We May Become a Party to Intellectual Property Infringement Claims, Which Could Harm Our Business.

     We are aware of certain pending lawsuits involving intellectual property infringement claims against businesses providing electronic payment gateway services that seek injunctive relief and monetary damages, which lawsuits were brought by a company that claims to hold patents related to such services. From time to time, we may be forced to respond to or prosecute intellectual property infringement claims to protect our rights or defend a client’s rights. These claims, regardless of merit, may consume valuable management time, result in costly litigation or cause product shipment delays, all of which could seriously harm our business and operating results. Furthermore, parties making such claims may be able to obtain injunctive or other equitable relief that could effectively block our ability to make, use, sell or otherwise practice our intellectual property, whether or not patented or described in pending patent applications, or to further develop or commercialize our products in the U.S. and abroad and could result in the award of substantial damages against us.

34

We may be required to enter into royalty or licensing agreements with third parties claiming infringement by us of their intellectual property in order to settle these claims. These royalty or licensing agreements, if available, may not have terms that are acceptable to us. In addition, if we are forced to enter into a license agreement with terms that are unfavorable to us, our operating results would be materially harmed. We may also be required to indemnify our clients for losses they may incur under indemnification agreements if we are found to have violated the intellectual property rights of others.

Our Business Could Require Additional Financing.

     Our future business activities, including our operation of Authorize.Net, the development or acquisition of new or enhanced products and services, the acquisition of additional computer and network equipment, the relocation of our corporate headquarters, and the international expansion of our business will require us to make significant capital expenditures. If our available cash resources prove to be insufficient, because of unanticipated expenses, revenue shortfalls or otherwise, we may need to seek additional financing or curtail our expansion activities. If we obtain equity financing for any reason, our existing stockholders may experience dilution in their investments. If we obtain debt financing, our business could become subject to restrictions that affect our operations or increase the level of risk in our business. It is also possible that, if we need additional financing, we will not be able to obtain it on acceptable terms, or at all.

Our Anti-Takeover Provisions May Discourage Potential Acquisitions or Changes of Control.

     Some provisions of our certificate of incorporation and Delaware law could be used by our incumbent management to make it more difficult for a third party to acquire control of us, even if the change in control might be beneficial to our stockholders. This could discourage potential takeover attempts and could adversely affect the market price of our common stock.

     In particular, we may issue preferred stock in the future without stockholder approval, upon terms determined by our board of directors. The rights of holders of our common stock would be subject to, and may be adversely affected by, the rights of holders of any preferred stock issued in the future. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of our outstanding stock. We also have adopted a stockholder rights plan that may deter or delay attempts to acquire us or to accumulate shares of common stock. Except for the stockholder rights plan, we have no present plans to designate or issue any shares of preferred stock.

     In addition, the members of our Board of Directors serve staggered three-year terms, with approximately one-third of the members elected each year. This structure makes it more difficult for stockholders to change the composition of a majority of our Board.

ITEM 3. QUANTITATIVE AND QUALITATIVE MARKET RISK DISCLOSURES.

     The market risk exposure inherent in the Company’s financial instruments and consolidated financial position represents the potential losses arising from adverse changes in interest rates. The Company is exposed to such interest rate risk primarily in its significant investment in cash and cash equivalents. Cash and cash equivalents include short-term, highly liquid instruments, which consist primarily of money market accounts, purchased with remaining maturities of three months or less. The Company’s short-term investments also include debt securities maturing in one year or less that are classified as available for sale. These investments are carried at fair value. The Company does not execute transactions in or hold derivative financial instruments for trading or hedging purposes.

35

     The carrying value of available-for-sale debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Realized gains and losses, and declines in value judged to be other than temporary on available-for-sale debt securities, if any, are included in interest income, net. The cost of securities sold is based on the specific identification method. Interest and dividends on securities are included in interest income, net.

     Market risk for cash and cash equivalents is estimated as the potential change in the fair value of the assets or obligations resulting from a hypothetical ten percent adverse change in interest rates, which would not have been significant to the Company’s financial position or results of operations during the quarter ended March 31, 2004.

     The Company is not subject to any material market risk associated with foreign currency exchange rates.

ITEM 4. CONTROLS AND PROCEDURES.

     The Company evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of March 31, 2004. This evaluation did not apply to Authorize.Net and its business since the acquisition of Authorize.Net was effective on the close of business on March 31, 2004. The Company’s Chief Executive Officer and its Chief Financial Officer supervised and participated in this evaluation. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2004, the Company’s disclosure controls and procedures (excluding those of Authorize.Net) were effective to provide a reasonable level of assurance of reaching the Company’s disclosure control objectives.

     There has not been any change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) that occurred in the quarter ended March 31, 2004 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
