(the “Company” or “Rambus”) is a premier intellectual property and technology licensing company. The Company was incorporated in California in March 1990 and reincorporated in Delaware in March 1997. The Company’s primary focus is the creation, design, development and licensing of patented innovations, technologies and architectures that are foundational to nearly all digital electronics products and systems. The Company’s patented innovations and technologies aim to improve the performance, power efficiency, <font style="white-space: nowrap">time-to-market</font> and cost-effectiveness of its customers’ products, components and systems offered and used in semiconductors, computers, mobile applications, gaming and graphics, consumer electronics, lighting displays and general lighting. By licensing its patented innovations and technologies, the Company hopes to continuously enrich the end-user experience of the digital electronics products and systems marketed and sold by its customers and licensees. The Company believes it has established an unparalleled licensing platform and business model that will continue to foster the development of new foundational and leading innovations and technologies. As a result, the Company’s goal is to create significant licensing opportunities, and thereby perpetuate strong company operating performance and long term stockholder value. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> While the Company has historically focused its efforts in developing and licensing patented innovations and technologies for the semiconductor industry, particularly within chip interfaces, it has initiated diversification efforts to expand its portfolio of patented innovations and technologies into lighting and displays, mobile communications, and additional semiconductor technologies. The Company expects to continue this diversification initiative through the acquisition of assets and the hiring of the inventors, scientists and engineers who will lead the effort to further develop these patented innovations and technologies in these new areas of focus. During 2010, the Company initiated an internal structural reorganization to establish separate business groups for its semiconductor industry focused operations (SBG) and operations focused on new or emerging licensing opportunities (NBG) which includes the LDT group. </div> </div>

For the licensing agreements with fixed royalty payments, Rambus generally recognizes revenue from these arrangements as amounts become due. For the licensing agreements with variable royalty payments which can be based on either a percentage of sales or number of units sold, Rambus earns royalties at the time that the licensees’ sales occur. Rambus’ licensees, however, do not report and pay royalties owed for sales in any given quarter until after the conclusion of that quarter.

These SOPs apply to all entities that earn revenue on products containing software, where software is not incidental to the product as a whole. Contract fees for the products and services provided under these arrangements are comprised of license fees and engineering service fees which are not essential to the functionality of the product. Rambus’ rates for PCS and for engineering services are specific to each development contract and not standardized in terms of rates or length.

Computer equipment, computer software and furniture and fixtures are stated at cost and depreciated on a straight-line basis over an estimated useful life of three years. The Company undertook a series of structural improvements to ready the Sunnyvale and Brecksville facilities for its use. The Company concluded that its requirement to fund construction costs and responsibility for cost overruns resulted in the Company being considered the owner of the buildings during the construction period for accounting purposes. Following substantial completion of construction, the Company occupied both facilities. At completion, the Company concluded that it retained sufficient continuing involvement to preclude de-recognition of the buildings under the FASB authoritative guidance applicable to sale leaseback for real estate. As such, the Company continues to account for the buildings as owned real estate and to record an imputed financing obligation for our obligation to the legal owners. The buildings will be depreciated on a straight-line basis over an estimated useful life of 15 to 39 years. See Note 5, “Balance Sheet Details,” and Note 7, “Commitments and Contingencies,” for additional details. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the initial terms of the leases.

Diluted earnings (loss) per share is calculated by dividing the earnings (loss) by the weighted average number of common shares and potentially dilutive securities outstanding during the period. Potentially dilutive common shares consist of incremental common shares issuable upon exercise of stock options, employee stock purchases, restricted stock and restricted stock units, and shares issuable upon the conversion of convertible notes. The dilutive effect of outstanding shares is reflected in diluted earnings per share by application of the treasury stock method. This method includes consideration of the amounts to be paid by the employees, the amount of excess tax benefits that would be recognized in equity if the instrument was exercised and the amount of unrecognized stock-based compensation related to future services. No potential dilutive common shares are included in the computation of any diluted per share amount when a net loss is reported.

The accounting treatment for goodwill, requires that companies not amortize goodwill, but instead test for impairment at least annually using a two-step approach. The Company evaluates goodwill, at a minimum, on an annual basis and whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. Impairment of goodwill is tested at the reporting unit level by comparing each reporting unit’s carrying amount, including goodwill, to the fair value of the reporting unit. The fair values of the reporting units are estimated using a combination of the income, or discounted cash flows, approach and the market approach, which utilizes comparable companies’ data. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered impaired and a second step is performed to measure the amount of impairment. The second step involves determining the fair value of goodwill for each reporting unit. Any excess carrying amount of goodwill over the fair value determined in the second step will be recorded as a goodwill impairment loss. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The Company reorganized its reporting structure in the third quarter of 2010 based on organizational changes within the Company.

The License Agreement requires that Samsung pay the Company cash payments over the next five years of (i) a fixed amount of $25.0 million each quarter during 2010 and the first two quarters of 2011, and (ii) thereafter, $25.0 million adjusted up or down based on certain levels of Samsung revenue for DRAM products licensed under the License Agreement for each quarter after 2010 and subject to a minimum of $10.0 million and a maximum of $40.0 million for each quarter. In addition, additional payments or certain adjustments to the payments by Samsung to the Company under the License Agreement may be due for certain acquisitions of businesses or assets by Samsung involving licensed products. The License Agreement and the licenses granted thereunder may be terminated upon a material breach by a party of its obligations under the agreement, a bankruptcy event involving a party or a change of control of Samsung subject to certain conditions. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Under the Stock Purchase Agreement, on January 19, 2010, Samsung purchased for cash from the Company 9.6 million shares of common stock of the Company (the “Shares”) with certain restrictions and put rights. The number of shares issued was based on a price per share equal to $20.885 (which was the average of the open and close trading price of Rambus common stock on The NASDAQ Global Select Market on January 15, 2010, the last trading day prior to the date of the Stock Purchase Agreement). The Shares represented approximately 8.3% of the total outstanding shares of Rambus common stock at that time after giving effect to the issuance thereof. The issuance of the Shares by the Company to Samsung was made through a private transaction. The Stock Purchase Agreement provides Samsung a one-time put right, beginning 18 months after the date of the Stock Purchase Agreement and extending to 19 months after the date of the Stock Purchase Agreement, to elect to put back to the Company up to 4.8 million of the Shares at the original issue price of $20.885 per share (for an aggregate purchase price of up to $100.0 million). </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The Stock Purchase Agreement prohibits the transfer of the Shares by Samsung for 18 months after the date of the Stock Purchase Agreement, subject to certain exceptions. After expiration of the transfer restriction period, the Stock Purchase Agreement provides that Samsung may transfer a limited number of shares on a daily basis, provides Rambus with a right of first offer for proposed transfers above such daily limits, and, if no sale occurs to Rambus under the right of first offer, allows Samsung to transfer the Shares. Under the Stock Purchase Agreement, the Company has also agreed that after the transfer restriction period, Samsung will have certain rights to register the Shares for sale under the securities laws of the United States, subject to customary terms and conditions. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> In addition, until 18 months after the date of the Stock Purchase Agreement, subject to customary exceptions, Samsung is subject to a standstill agreement that prohibits Samsung from, among other things, acquiring additional shares of common stock of the Company, commencing or endorsing any tender offer or exchange offer for shares of common stock of the Company, participating in any solicitation of proxies with respect to voting any shares of common stock of the Company, or announcing or submitting any proposal or offer concerning any extraordinary transaction involving the Company. Samsung is also subject to a voting agreement under the Stock Purchase Agreement that provides that Samsung will vote its Shares in favor of routine proposals (related to election of directors, certain compensation matters, authorized share capital increases and approval of the independent auditors) that are recommended by the Board of Directors of the Company at any stockholder meeting. In all other matters, the voting agreement contained in the Stock Purchase Agreement requires that Samsung vote its Shares in the same proportion as the votes that are cast by all other holders of shares of common stock of the Company. The voting agreement under the Stock Purchase Agreement terminates (i) with respect to Shares that Samsung transfers in accordance with the provisions of the Stock Purchase Agreement, (ii) upon a change of control or bankruptcy event involving the Company or (iii) when Samsung owns less than 3% of the outstanding shares of common stock of the Company. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The Samsung Settlement is a multiple element arrangement for accounting purposes. For the multiple element arrangement, the Company identified each element of the arrangement and determined when those elements should be recognized. Using the accounting guidance from multiple element revenue arrangements, the Company allocated the consideration to each element using the estimated fair value of the elements. The Company considered several factors in determining the accounting fair value of the elements of the Samsung Settlement which included a third party valuation using an income approach, the Black-Scholes option pricing model and a residual approach (collectively the “Fair Value”). The inputs and assumptions used in this valuation were from a market participant perspective and included projected revenue, royalty rates, estimated discount rates, useful lives and income tax rates, among others. The development of a number of these inputs and assumptions in the model requires a significant amount of management judgment and is based upon a number of factors, including the selection of industry comparables, market growth rates and other relevant factors. Changes in any number of these assumptions may have had a substantial impact on the Fair Value as assigned to each element. These inputs and assumptions represent management’s best estimates at the time of the transaction. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%;

The Company holds all of its marketable securities as <font style="white-space: nowrap">available-for-sale,</font> marks them to market, and regularly reviews its portfolio to ensure adherence to its investment policy and to monitor individual investments for risk analysis, proper valuation, and unrealized losses that may be other than temporary. As of December 31, 2010, marketable debt securities with a fair value of $178.2 million, which mature within one year, had insignificant unrealized losses. The Company has no intent to sell, there is no requirement to sell and the Company believes that it can recover the amortized cost of these investments. The Company has found no evidence of impairment due to credit losses in its portfolio. Therefore, these unrealized losses were recorded in other comprehensive income (loss). However, the Company cannot provide any assurance that its portfolio of cash, cash equivalents and marketable securities will not be impacted by adverse conditions in the financial markets, which may require the Company in the future to record an impairment charge for credit losses which could adversely impact its financial results. </div> <div style="margin-top: 6pt;

The Company undertook a series of structural improvements to ready the space for its use. The Company concluded that its requirement to fund construction costs and responsibility for cost overruns resulted in the Company being considered the owner of the building during the construction period for accounting purposes. Therefore, as of December 31, 2009, the Company capitalized approximately $25.1 million as construction in progress, based on the estimated fair value of the existing portion of the unfinished building, along with a corresponding financing obligation for the building. The fair value was determined as of December 31, 2009 using level 3 fair value inputs (defined as prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity)) and the cost approach which measures the value of an asset as the cost to reconstruct or replace it with another asset of like utility. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Following substantial completion of construction in the fourth quarter of 2010, the Company occupied the Sunnyvale facility. At completion, the Company concluded that it retained sufficient continuing involvement to preclude de-recognition of the building under the FASB authoritative guidance applicable to sale leasebacks of real estate. As such, the Company continues to account for the building as owned real estate and to record an imputed financing obligation for its obligation to the legal owner. The building is reflected as an asset on the Company’s balance sheet throughout the initial ten year term of the lease, the period of intended use. In addition, the Company capitalized $1.5 million of interest on the building along with a related imputed financing obligation for the same amount and $13.1 million of construction costs related to the build-out of the new facility. At December 31, 2010, total building costs of $39.7 million are reflected as an asset on the Company’s balance sheet. The Company expects to incur an additional $0.8 million of construction costs in 2011. The building is depreciated on a straight-line basis over a period of approximately 39 years.

The office space is used for the Company’s corporate headquarters, as well as engineering, marketing and administrative operations and activities. The Company moved to the new premises in the fourth quarter of 2010 following substantial completion of leasehold improvements. The Sunnyvale Lease has a term of 120 months from the commencement date. The initial annual base rent is $3.7 million, subject to a full abatement of rent for the first six months of the Sunnyvale Lease term, but with the rent for the seventh month paid in December 2009 in order to gain access to the building. The annual base rent increases each year to certain fixed amounts over the course of the term as set forth in the Sunnyvale Lease and will be $4.8 million in the tenth year. In addition to the base rent, the Company also pays operating expenses, insurance expenses, real estate taxes and a management fee. The Company has two options to extend the Sunnyvale Lease for a period of 60 months each and a one-time option to terminate the Sunnyvale Lease after 84 months in exchange for an early termination fee. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Since certain improvements to be constructed by the Company are considered structural in nature and the Company is responsible for any cost overruns, for accounting purposes, the Company is treated in substance as the owner of the construction project during the construction period.

The Company expects the remaining $8.8 million to be received in 2011. The Company recognized the $0.3 million reimbursement as additional imputed financing obligation under the FASB authoritative guidance as such payment from the landlord is deemed to be an imputed financing obligation. Monthly lease payments on the facility are allocated between the land element of the lease (which is accounted for as an operating lease) and the imputed financing obligation. The imputed financing obligation is amortized using the effective interest method and the interest rate determined in accordance with the requirements of sale leaseback accounting. For the year ended December 31, 2010, the Company recognized in its statement of operations $0.4 million of interest expense in connection with the imputed financing obligation. At December 31, 2010, the imputed financing obligation balance in connection with the new facility was $27.3 million, of which $0.2 million was classified under other accrued liabilities in the current liabilities section and $27.1 million was classified under long-term imputed financing obligation.

The Company moved to the new premises at the end of the third quarter of 2010 following substantial completion of leasehold improvements. The warehouse area was converted into office space and manufacturing space. The office space is used for the LDT group’s engineering activities while the manufacturing space is used for the manufacturer of prototypes for the LDT group. The Ohio Lease has a term of 60 months from the commencement date which is the earlier of (i) the date upon which the Company first takes occupancy of the premises once the construction work is completed or (ii) the first day of the month following completion and notification by the lessor to the Company of completion of construction of the building. The initial annual base rent is approximately $136,000. In addition to the base rent, the Company also pays operating expenses, insurance expenses, real estate taxes and a management fee.

At the end of the initial five year lease term in 2015, the Company has an option to renew the lease for an additional 60 months. As a result of the significant amount of construction costs, the Company currently would expect to renew the lease for an additional 60 months so the lease term for accounting purposes will be the period of intended use of ten years. The lease payments are recorded as interest expense using the effective interest method over the term of the lease and the building is depreciated on a straight-line basis over a period of 15 years. For the year ended December 31, 2010, the Company recognized in its statement of operations $29 thousand of interest expense in connection with the imputed financing obligation. At December 31, 2010, the imputed financing obligation balance in connection with the new facility was $0.8 million, which was classified under long-term imputed financing obligation.

Although the Company does not indemnify most of its customers, there are times when an indemnification is a necessary means of doing business. Indemnifications cover customers for losses suffered or incurred by them as a result of any patent, copyright, or other intellectual property infringement claim by any third party with respect to the Company’s products. The maximum amount of indemnification the Company could be required to make under these agreements is generally limited to fees received by the Company. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Several securities fraud class actions, private lawsuits and shareholder derivative actions were filed in state and federal courts against certain of the Company’s current and former officers and directors related to the stock option granting actions. As permitted under Delaware law, the Company has agreements whereby its officers and directors are indemnified for certain events or occurrences while the officer or director is, or was serving, at the Company’s request in such capacity. The term of the indemnification period is for the officer’s or director’s term in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. The Company has a director and officer insurance policy that reduces the Company’s exposure and enables the Company to recover a portion of future amounts to be paid. As a result of these indemnification agreements, the Company continues to make payments on behalf of current and former officers. As of December 31, 2010 and 2009, respectively, the Company had made payments of approximately $15.7 million and $11.4 million on their behalf. These payments were recorded under costs of restatement and related legal activities in the consolidated statements of operations. The Company has received approximately $5.3 million from the former officers related to their settlement agreements with the Company in connection with the derivative and class action lawsuits which was comprised of approximately $4.5 million in cash received in the first quarter of 2009 as well as approximately 163,000 shares of the Company’s stock with a value of approximately $0.8 million in the fourth quarter of 2008. Additionally, as of December 31, 2010, the Company has received $12.3 million from insurance settlements related to the defense of the Company, its directors and its officers which were recorded under costs (recoveries) of restatement and related legal activities in the consolidated statements of operations. </div> </div>

Grants under all plans typically have a requisite service period of 60 months, have straight-line or graded vesting schedules (the 1997 and 1999 plans only) and expire not more than ten years from date of grant.

The 2006 Plan, as amended, provides for the issuance of the following types of incentive awards: (i) stock options; (ii) stock appreciation rights; (iii) restricted stock; (iv) restricted stock units; (v) performance shares and performance units; and (vi) other stock or cash awards. This plan provides for the granting of awards at less than fair market value of the common stock on the date of grant, but such grants would be counted against the numerical limits of available shares at a ratio of 1.5 to 1. The Board of Directors reserved 8,400,000 shares in March 2006 for issuance under this plan, subject to stockholder approval. Upon stockholder approval of this Plan on May 10, 2006, the 1997 Plan was replaced and the 1999 Plan was terminated. On April 30, 2009, stockholders approved additional 6,500,000 shares for issuance under the 2006 Plan. Those who will be eligible for awards under the 2006 Plan include employees, directors and consultants who provide services to the Company and its affiliates. These options typically have a requisite service period of 60 months, have straight-line vesting schedules, and expire not more than ten years from date of grant.

These variables include expected volatility, expected life of the award, expected dividend rate, and expected risk-free rate of return.

These awards have a service condition, generally a service period of four years, except in the case of grants to directors, for which the service period is one year. The nonvested equity stock units were valued at the date of grant giving them a fair value of approximately $6.6 million. The Company occasionally grants nonvested equity stock units to its employees with vesting subject to the achievement of certain performance conditions. During the year ended December 31, 2010, the achievement of certain performance conditions for certain performance equity stock units was considered probable, and as a result, the Company recognized an immaterial amount of stock-based compensation expense related to these performance stock units. During the years ended December 31, 2009 and 2008, the Company did not recognize any compensation expense for any performance equity stock units since the performance conditions had not been met. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> For the years ended December 31, 2010, 2009, and 2008, the Company recorded stock-based compensation expense of approximately $6.3 million, $5.4 million and $3.1 million, respectively, related to all outstanding equity stock grants. Beginning in 2008, compensation expense was adjusted for an estimate of forfeitures for non performance-based grants, based on management’s future expectations. Unrecognized stock-based compensation related to all nonvested equity stock grants, net of an estimate of forfeitures, was approximately $8.9 million at December 31, 2010.

Under the Share Repurchase Agreement, the Company pre-paid to J.P. Morgan the $90.0 million purchase price in the third quarter of 2010 for the Common Stock and J.P. Morgan delivered to the Company approximately 4.8 million shares of Common Stock at an average price of $18.88 at the completion of the Share Repurchase Agreement in December 2010. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> For the year ended December 31, 2010, the Company repurchased approximately 9.5 million shares of its Common Stock with an aggregate price of approximately $195.1 million, including the price paid pursuant to the Share Repurchase Agreement.

The Company records a portion of the purchase price of the repurchased shares as an increase to accumulated deficit when the price of the shares repurchased exceeds the average original proceeds per share received from the issuance of Common Stock. During the year ended December 31, 2010, the cumulative price of the shares repurchased exceeded the proceeds received from the issuance of the same number of shares. The excess of $163.6 million was recorded as an increase to accumulated deficit for the year ended December 31, 2010. During the year ended December 31, 2009, the Company did not repurchase any Common Stock. </div> </div>

For the year ended December 31, 2010, the Company’s valuation allowance was reduced to $75.4 million as a result of utilizing net operating loss and credit carryforwards against its taxable income. Management periodically evaluates the realizability of the Company’s net deferred tax assets based on all available evidence, both positive and negative. The realization of net deferred tax assets is dependent on the Company’s ability to generate sufficient future taxable income during periods prior to the expiration of tax statutes to fully utilize these assets. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The Company weighed both positive and negative evidence and determined that there is a continued need for a valuation allowance due to projected future losses, which the Company considered significant negative evidence. Though considered positive evidence, potential income from favorable patent and related settlement litigation were not included in the determination for the valuation allowance due to the Company’s inability to reliably estimate the timing and amounts of such settlements. Even though the Company is no longer in a cumulative loss position, the projection of significant future losses is a negative factor that outweighs the positive factors leading to a conclusion that a release of the valuation allowance is not yet appropriate. If any settlement income is realized, the Company will reassess its position on maintaining the valuation allowance. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> As of December 31, 2010, Rambus has federal and state net operating loss carryforwards for income tax purposes of $84.5 million and $245.9 million, respectively, which begin to expire in 2018.

Diluted earnings (loss) per share is calculated by dividing the earnings (loss) by the weighted average number of common shares and potentially dilutive securities outstanding during the period. Potentially dilutive common shares consist of incremental common shares issuable upon exercise of stock options, employee stock purchases, restricted stock and restricted stock units and shares issuable upon the conversion of convertible notes. The dilutive effect of outstanding shares is reflected in diluted earnings per share by application of the treasury stock method. This method includes consideration of the amounts to be paid by the employees, the amount of excess tax benefits that would be recognized in equity if the instrument was exercised and the amount of unrecognized stock-based compensation related to future services. No potential dilutive common shares are included in the computation of any diluted per share amount when a net loss is reported. As discussed in Note 3, “Settlement Agreement with Samsung,” the Company reported approximately 4.8 million shares issued to Samsung as contingently redeemable common stock due to the contractual put rights associated with those shares. As such, the Company uses the two-class method for reporting earnings per share. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%;

In its January 4, 2006 Findings of Fact and Conclusions of Law, the court held that Hynix’s unclean hands defense failed. Among other things, the court found that Rambus did not adopt its document retention policy in bad faith, did not engage in unlawful spoliation of evidence, and that while Rambus disposed of some relevant documents pursuant to its document retention policy, Hynix was not prejudiced by the destruction of Rambus documents. On January 19, 2009, Hynix filed a motion for reconsideration of the court’s unclean hands order and for summary judgment on the ground that the decision by the Delaware court in the pending Micron-Rambus litigation (described below) should be given preclusive effect. In its motion Hynix requested alternatively that the court’s unclean hands order be certified for appeal and that the remainder of the case be stayed. Rambus filed an opposition to Hynix’s motion on January 26, 2009, and a hearing was held on January 30, 2009. On February 3, 2009, the court denied Hynix’s motions and restated its conclusions that Rambus had not anticipated litigation until late 1999 and that Hynix had not demonstrated any prejudice from any alleged destruction of evidence. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The second phase of the Hynix-Rambus trial — on patent infringement, validity and damages — began on March 15, 2006, and was submitted to the jury on April 13, 2006. On April 24, 2006, the jury returned a verdict in favor of Rambus on all issues and awarded Rambus a total of approximately $307 million in damages, excluding prejudgment interest. Specifically, the jury found that each of the ten selected patent claims was supported by the written description, and was not anticipated or rendered obvious by prior art; therefore, none of the patent claims was invalid. The jury also found that Hynix infringed all eight of the patent claims for which the jury was asked to determine infringement; the court had previously determined on summary judgment that Hynix infringed the other two claims at issue in the trial. On July 14, 2006, the court granted Hynix’s motion for a new trial on the issue of damages unless Rambus agreed to a reduction of the total jury award to approximately $134 million. The court found that the record supported a maximum royalty rate of 1% for SDR SDRAM and 4.25% for DDR SDRAM, which the court applied to the stipulated U.S. sales of infringing Hynix products through December 31, 2005. On July 27, 2006, Rambus elected remittitur of the jury’s award to approximately $134 million. On August 30, 2006, the court awarded Rambus prejudgment interest for the period June 23, 2000 through December 31, 2005. Hynix filed a motion on July 7, 2008 to reduce the amount of remitted damages and any supplemental damages that the court may award, as well as to limit the products that could be affected by any injunction that the court may grant, on the grounds of patent exhaustion. Following a hearing on August 29, 2008, the court denied Hynix’s motion. In separate orders issued December 2, 2008, January 16, 2009, and January 27, 2009, the court denied Hynix’s post-trial motions for judgment as a matter of law and new trial on infringement and validity. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> On June 24, 2008, the court heard oral argument on Rambus’ motion to supplement the damages award and for equitable relief related to Hynix’s infringement of Rambus patents. On February 23, 2009, the court issued an order (1) granting Rambus’ motion for supplemental damages and prejudgment interest for the period after December 31, 2005, at the same rates ordered for the prior period; (2) denying Rambus’ motion for an injunction; and (3) ordering the parties to begin negotiations regarding the terms of a compulsory license regarding Hynix’s continued manufacture, use, and sale of infringing devices. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The third phase of the Hynix-Rambus trial involved Hynix’s affirmative JEDEC-related antitrust and fraud allegations against Rambus. On April 24, 2007, the court ordered a coordinated trial of certain common JEDEC-related claims alleged by the manufacturer parties (i.e., Hynix, Micron, Nanya and Samsung) and defenses asserted by Rambus in <i>Hynix v Rambus, </i>Case No. C <font style="white-space: nowrap">00-20905</font> RMW, and three other cases pending before the same court (<i>Rambus Inc. v.

Micron Technology, Inc., et al.</i>, Case No. C <font style="white-space: nowrap">06-00244</font> RMW, each described in further detail below). On December 14, 2007, the court excused Samsung from the coordinated trial based on Samsung’s agreement to certain conditions, including trial of its claims against Rambus by the court within six months following the conclusion of the coordinated trial. The coordinated trial involving Rambus, Hynix, Micron and Nanya began on January 29, 2008, and was submitted to the jury on March 25, 2008. On March 26, 2008, the jury returned a verdict in favor of Rambus and against Hynix, Micron, and Nanya on each of their claims. Specifically, the jury found that Hynix, Micron, and Nanya failed to meet their burden of proving that: (1) Rambus engaged in anticompetitive conduct; (2) Rambus made important representations that it did not have any intellectual property pertaining to the work of JEDEC and intended or reasonably expected that the representations would be heard by or repeated to others including Hynix, Micron or Nanya; (3) Rambus uttered deceptive half-truths about its intellectual property coverage or potential coverage of products compliant with synchronous DRAM standards then being considered by JEDEC by disclosing some facts but failing to disclose other important facts; or (4) JEDEC members shared a clearly defined expectation that members would disclose relevant knowledge they had about patent applications or the intent to file patent applications on technology being considered for adoption as a JEDEC standard. Hynix, Micron, and Nanya filed motions for a new trial and for judgment on certain of their equitable claims and defenses. A hearing on those motions was held on May 1, 2008. A further hearing on the equitable claims and defenses was held on May 27, 2008. On July 24, 2008, the court issued an order denying Hynix, Micron, and Nanya’s motions for new trial. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> On March 3, 2009, the court issued an order rejecting Hynix, Micron, and Nanya’s equitable claims and defenses that had been tried during the coordinated trial. The court concluded (among other things) that (1) Rambus did not have an obligation to disclose pending or anticipated patent applications and had sound reasons for not doing so; (2) the evidence supported the jury’s finding that JEDEC members did not share a clearly defined expectation that members would disclose relevant knowledge they had about patent applications or the intent to file patent applications on technology being considered for adoption as a JEDEC standard; (3) the written JEDEC disclosure policies did not clearly require members to disclose information about patent applications and the intent to file patent applications in the future; (4) there was no clearly understood or legally enforceable agreement of JEDEC members to disclose information about patent applications or the intent to seek patents relevant to standards being discussed at JEDEC; (5) during the time Rambus attended JEDEC meetings, Rambus did not have any patent application pending that covered a JEDEC standard, and none of the patents in suit was applied for until well after Rambus resigned from JEDEC; (6) Rambus’s conduct at JEDEC did not constitute an estoppel or waiver of its rights to enforce its patents; (7) Hynix, Micron, and Nanya failed to carry their burden to prove their asserted waiver and estoppel defenses not directly based on Rambus’s conduct at JEDEC; (8) the evidence did not support a finding of any material misrepresentation, half truths or fraudulent concealment by Rambus related to JEDEC upon which Nanya relied; (9) the manufacturers failed to establish that Rambus violated unfair competition law by its conduct before JEDEC; (10) the evidence related to Rambus’s patent prosecution did not establish that Rambus unduly delayed in prosecuting the claims in suit; (11) Rambus did not unreasonably delay bringing its patent infringement claims; and (12) there is no basis for any unclean hands defense or unenforceability claim arising from Rambus’s conduct. </div>  </div>   <div style="margin-left: 0%">  <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div> <div style="margin-top: 0pt; font-size: 1pt"> </div> <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div>  <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> On March 10, 2009, the court entered final judgment against Hynix in the amount of approximately $397 million as follows: approximately $134 million for infringement through December 31, 2005; approximately $215 million for infringement from January 1, 2006 through January 31, 2009; and approximately $48 million in pre-judgment interest. Post-judgment interest is accruing at the statutory rate. In addition, the judgment orders Hynix to pay Rambus royalties on net sales for U.S. infringement after January 31, 2009 and before April 18, 2010 of 1% for SDR SDRAM and 4.25% for DDR DDR2, DDR3, GDDR, GDDR2 and GDDR3 SDRAM memory devices. On April 9, 2009, Rambus submitted its cost bill in the amount of approximately $0.85 million. On March 24, 2009, Hynix filed a motion under Rule 62 seeking relief from the requirement that it post a supersedeas bond in the full amount of the final judgment in order to stay its execution pending an appeal. Rambus filed a brief opposing Hynix’s motion on April 10, 2009. A hearing on Hynix’s motion was heard on May 8, 2009. On May 14, 2009, the court granted Hynix’s motion in part and ordered that execution of the judgment be stayed on the condition that, within 45 days, Hynix post a supersedeas bond in the amount of $250 million and provide Rambus with documentation establishing a lien in Rambus’s favor on property owned by Hynix in Korea in the amount of the judgment not covered by the supersedeas bond. The court also ordered that Hynix pay the ongoing royalties set forth in the final judgment into an escrow account. Hynix posted the $250 million supersedeas bond on June 26, 2009. On September 17, 2010, the court granted Rambus’s motion for reconsideration of the portion of its order allowing Hynix to establish a lien in lieu of posting a bond for a portion of the judgment; on October 18, 2010, Hynix posted a bond in the full amount of the judgment plus accrued post-judgment interest in the total amount of $401.2 million. Hynix has deposited amounts into the escrow account pursuant to the court’s order regarding ongoing royalties. The escrowed funds will be released only upon agreement of the parties or further court order in accordance with the terms and conditions set forth in the escrow arrangement. On March 8, 2010, the court awarded costs to Rambus in the amount of approximately $0.76 million. That amount plus accrued interest has been deposited by Hynix into the same escrow account into which ongoing royalties have been deposited. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> On April 6, 2009, Hynix filed its notice of appeal.

On July 23, 2009, Rambus and Hynix filed a joint motion to assign this appeal to the same panel hearing the appeal in the Micron Delaware case (discussed below) and to coordinate oral arguments of the two appeals. On August 17, 2009, the United States Court of Appeals for the Federal Circuit issued an order 1) granting the joint motion to coordinate oral arguments of the two appeals; and 2) denying Hynix’s motion to dismiss Rambus’s cross-appeal.

Micron seeks a declaration of monopolization by Rambus, compensatory and punitive damages, attorneys’ fees, a declaratory judgment that eight Rambus patents are invalid and not infringed, and the award to Micron of a royalty-free license to the Rambus patents.

The court ordered post-trial briefing on the issue of when Rambus became obligated to preserve documents because it anticipated litigation. A hearing on that issue was held on May 20, 2008.

On February 9, 2009, the court stayed all other proceedings pending appeal of the Delaware Order.

Hynix, Samsung and Nanya have denied Rambus’ claims and asserted counterclaims against Rambus for, among other things, violations of federal antitrust laws, unfair trade practices, equitable estoppel, and fraud in connection with Rambus’ participation in JEDEC. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> As explained above, the court ordered a coordinated trial of certain common JEDEC-related claims and defenses asserted in <i>Hynix v Rambus</i>, Case No. C <font style="white-space: nowrap">00-20905</font> RMW, <i>Rambus Inc. v.

The court subsequently excused Samsung from the coordinated trial on December 14, 2007, based on Samsung’s agreement to certain conditions, including trial of its claims against Rambus within six months following the conclusion of the coordinated trial. The coordinated trial involving Rambus, Hynix, Micron and Nanya began on January 29, 2008, and was submitted to the jury on March 25, 2008. On March 26, 2008, the jury returned a verdict in favor of Rambus and against Hynix, Micron, and Nanya on each of their claims. Specifically, the jury found that Hynix, Micron, and Nanya failed to meet their burden of proving that: (1) Rambus engaged in anticompetitive conduct; (2) Rambus made important representations that it did not have any intellectual property pertaining to the work of JEDEC and intended or reasonably expected that the representations would be heard by or repeated to others including Hynix, Micron or Nanya; (3) Rambus uttered deceptive half- truths about its intellectual property coverage or potential coverage of products compliant with synchronous DRAM standards then being considered by JEDEC by disclosing some facts but failing to disclose other important facts; or (4) JEDEC members shared a clearly defined expectation that members would disclose relevant knowledge they had about patent applications or the intent to file patent applications on technology being considered for adoption as a JEDEC standard. Hynix, Micron, and Nanya filed motions for a new trial and for judgment on certain of their equitable claims and defenses. A hearing on those motions was held on May 1, 2008. A further hearing on the equitable claims and defenses was held on May 27, 2008. On July 24, 2008, the court issued an order denying Hynix, Micron, and Nanya’s motions for new trial. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> On March 3, 2009, the court issued an order rejecting Hynix, Micron, and Nanya’s equitable claims and defenses that had been tried during the coordinated trial. The court concluded (among other things) that (1) Rambus did not have an obligation to disclose pending or anticipated patent applications and had sound reasons for not doing so; (2) the evidence supported the jury’s finding that JEDEC members did not share a clearly defined expectation that members would disclose relevant knowledge they had about patent applications or the intent to file patent applications on technology being considered for adoption as a JEDEC standard; (3) the written JEDEC disclosure policies did not clearly require members to disclose information about patent applications and the intent to file patent applications in the future; (4) there was no clearly understood or legally enforceable agreement of JEDEC members to disclose information about patent applications or the intent to seek patents relevant to standards being discussed at JEDEC; (5) during the time Rambus attended JEDEC meetings, Rambus did not have any patent application pending that covered a JEDEC standard, and none of the patents in suit was applied for until well after Rambus resigned from JEDEC; (6) Rambus’s conduct at JEDEC did not constitute an estoppel or waiver of its rights to enforce its patents; (7) Hynix, Micron, and Nanya failed to carry their burden to prove their asserted waiver and estoppel defenses not directly based on Rambus’s conduct at JEDEC; (8) the evidence did not support a finding of any material misrepresentation, half truths or fraudulent concealment by Rambus related to JEDEC upon which Nanya relied; (9) the manufacturers failed to establish that Rambus violated unfair competition law by its conduct before JEDEC; (10) the evidence related to Rambus’s patent prosecution did not establish that Rambus unduly delayed in prosecuting the claims in suit; (11) Rambus did not unreasonably delay bringing its patent infringement claims; and (12) there is no basis for any unclean hands defense or unenforceability claim arising from Rambus’s conduct. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> In these cases (except for the <i>Hynix </i><font style="white-space: nowrap">00-20905</font> action), a hearing on claim construction and the parties’ cross-motions for summary judgment on infringement and validity was held on June 4 and 5, 2008. On July 10, 2008, the court issued its claim construction order relating to the Farmwald/Horowitz patents in suit and denied the Manufacturers’ motions for summary judgment of noninfringement and invalidity based on their proposed claim construction. The court issued claim construction orders relating to the Ware patents in suit on July 25 and August 27, 2008, and denied the Manufacturers’ motion for summary judgment of noninfringement of certain claims. On September 4, 2008, at the court’s direction, Rambus elected to proceed to trial on 12 patent claims, each from the Farmwald/Horowitz family. On September 16, 2008, Rambus granted a covenant not to assert any claim of patent infringement against the Manufacturers under U.S. Patent Nos. 6,493,789 and 6,496,897, and each party’s claims relating to those patents were dismissed with prejudice. On November 21, 2008, the court entered an order clarifying certain aspects of its July 10, 2008, claim construction order. On November 24, 2008, the court granted Rambus’s motion for summary judgment of direct infringement with respect to claim 16 of Rambus’s U.S. Patent No. 6,266,285 by the Manufacturers’ DDR2, DDR3, gDDR2, GDDR3, GDDR4 memory chip products (except for Nanya’s DDR3 memory chip products).

Rambus answered the ensuing requests for information prompted by those complaints on June 16, 2003. Rambus obtained a copy of Infineon’s complaint to the European Commission in late July 2003, and on October 8, 2003, at the request of the European Commission, filed its response. The European Commission sent Rambus a further request for information on December 22, 2006, which Rambus answered on January 26, 2007.

The statement of objections alleges that through Rambus’ participation in the JEDEC standards setting organization and subsequent conduct, Rambus violated European Union competition law.

Under the terms of the settlement, the Commission made no finding of liability, and no fine will be assessed against Rambus. Rambus commits to offer licenses with maximum royalty rates for certain memory types and memory controllers on a forward-going basis (the “Commitment”). The Commitment is expressly made without any admission by Rambus of the allegations asserted against it. The Commitment also does not resolve any existing claims of infringement prior to the signing of any license with a prospective licensee, nor does it release or excuse any of the prospective licensees from damages or royalty obligations through the date of signing a license. Rambus offers licenses with maximum royalty rates for five-year worldwide licenses of 1.5% for DDR2, DDR3, GDDR3 and GDDR4 SDRAM memory types. Qualified licensees will enjoy a royalty holiday for SDR and DDR DRAM devices, subject to compliance with the terms of the license. In addition, Rambus offers licenses with maximum royalty rates for five-year worldwide licenses of 1.5% per unit for SDR memory controllers through April 2010, dropping to 1.0% thereafter, and royalty rates of 2.65% per unit for DDR, DDR2, DDR3, GDDR3 and GDDR4 memory controllers through April 2010, then dropping to 2.0%. The Commitment to license at the above rates remains valid for a period of five years from December 9, 2009. All royalty rates are applicable to future shipments only and do not affect liability, if any, for damages or royalties that accrued up to the time of the license grant. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> On March 25, 2010, Hynix filed appeals with the General Court of the European Union purporting to challenge the settlement and the European Commission’s rejection of Hynix’s complaint.

On January 20, 2011, NVIDIA filed a motion to stay the case pending resolution of the 2010 U.S. International Trade Commission (the “ITC”) investigation (described below).

The accused products include NVIDIA products that incorporate DDR, DDR2, DDR3, LPDDR, GDDR, GDDR2, and GDDR3 memory controllers, including graphics processors, and media and communications processors. The complaint names NVIDIA as a proposed respondent, as well as companies whose products incorporate accused NVIDIA products and are imported into the United States.

On June 5, 2009, Rambus moved to withdraw from the investigation four of the asserted patents and certain claims of a fifth asserted patent in order to simplify the investigation, streamline the final hearing, and conserve Commission resources. A final hearing before the administrative law judge was held October <font style="white-space: nowrap">13-20,</font> 2009, and the parties submitted two rounds of post-hearing briefs. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> On January 22, 2010, the administrative law judge issued a final initial determination holding that the importation of the accused NVIDIA products violates section 337 of the Tariff Act of 1930, as amended, 19 U.S.C. § 1337 because they infringe seventeen claims of three asserted Barth patents. The administrative law judge held that the accused NVIDIA products literally infringe all asserted claims of each asserted Barth and Ware patent, that they infringe three asserted claims under the doctrine of equivalents, that respondents contribute to and induce infringement of all asserted claims, and that the asserted patents are not unenforceable due to unclean hands or equitable estoppel. The administrative law judge held that the asserted Barth patents are not invalid for anticipation or obviousness and are not obvious for double patenting. The administrative law judge further held that, while the accused products infringed eight claims of the two asserted Ware patents and that those patents are not unenforceable due to inequitable conduct, no violation has occurred because the asserted Ware patents are invalid due to anticipation and obviousness. The administrative law judge recommended that the ITC issue (1) a limited exclusion order prohibiting the unlicensed importation of accused products by any respondent; and (2) a cease and desist order prohibiting domestic respondents from engaging in certain activities in the United States with respect to the accused products. On February 12, 2010, the parties’ filed petitions asking the full Commission to review certain aspects of the final initial determination. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> On March 25, 2010, the ITC determined to review certain obviousness findings regarding the Barth patents and certain obviousness and anticipation findings regarding the Ware patents. The parties have submitted briefing on these issues and on the issue of remedy and bonding. On May 24, 2010, the ITC extended the target date for completion of the investigation by two days to May 26, 2010. On May 26, 2010, the ITC requested further briefing on the impact of the license between Rambus and Samsung on the administrative law judge’s findings and conclusions, particularly on the issue of patent exhaustion. On June 7, 2010 and June 15, 2010, the parties filed briefs as requested by the ITC. On June 22, 2010, the ITC requested additional briefing to discuss the relevance and effect with respect to the issue of patent exhaustion of a decision issued on May 27, 2010, by the United States Court of Appeals for the Federal Circuit in a case captioned <i>Fujifilm Corp. v. Benun</i>.

The ITC found that respondents failed to demonstrate that Rambus’ patent rights are exhausted with respect to accused products that incorporate Samsung memory. The ITC issued (1) a limited exclusion order prohibiting the unlicensed importation by any respondent of memory controller products and products incorporating a memory controller that infringe one or more of the seventeen claims of three asserted Barth patents; and (2) a cease and desist order prohibiting respondents with commercially significant inventories of infringing products in the United States from importing, selling, marketing, advertising, distributing, offering for sale, transferring (except for exportation), and soliciting U.S. agents or distributors for, memory controller products and products incorporating a memory controller that infringe one or more of the seventeen claims of three asserted Barth patents, in violation of 19 U.S.C. § 1337. The ITC determined that the amount of the bond to permit importation during the <font style="white-space: nowrap">sixty-day</font> Presidential review period was 2.65 percent of the entered value of the subject imports. The ITC denied respondents’ request for stay and terminated the investigation.

The FASB convertible debt accounting guidance specifies that an issuer of such instruments should separately account for the liability and equity components of the instruments in a manner that reflects the issuer’s non-convertible debt borrowing rate when interest costs are recognized in subsequent periods. The debt component was determined based on a binomial lattice model. The equity component, recorded as additional paid-in capital, represents the difference between the proceeds from the issuance of the convertible notes and the fair value of the liability, net of deferred taxes, as of the date of issuance. The FASB convertible debt accounting guidance was effective for the Company’s fiscal year beginning January 1, 2009, and retrospective application is required for all periods presented. </div>  </div>   <div style="margin-left: 0%">  <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div> <div style="margin-top: 0pt; font-size: 1pt"> </div> <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div>  <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The adoption of the FASB convertible debt accounting guidance on January 1, 2009 impacted the historical accounting for the Company’s 2010 Notes as the Company’s 2010 Notes satisfy the criteria for accounting under the FASB convertible debt accounting guidance. The Company determined that the liability component of the 2010 Notes was $200.3 million and the equity component of the 2010 Notes was $99.7 million as of the date of issuance. The Company has accounted for this change in accounting principle by retrospectively adjusting prior period financial statements, including those set forth herein. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The debt component is accreted to par using the effective interest method and accretion is reported as a component of interest expense in the Company’s consolidated statements of operations. The interest expense attributed to the adoption of the FASB convertible debt accounting guidance for 2008 and 2007 was $11.8 million and $11.0 million, respectively, at an annualized effective interest rate of 8.4%. The adoption also resulted in a $22.0 million prior period cumulative adjustment in the consolidated balance sheets and the consolidated statement of stockholders’ equity and comprehensive loss that was included in the January 1, 2006 accumulated deficit beginning balance. The equity component is not required to be subsequently re-valued under the FASB convertible debt accounting guidance as long as it continues to qualify for equity treatment. The deferred financing costs associated with the issuance of the 2010 Notes were previously reported at $7.2 million. These costs have been allocated proportionately between the liability and equity components. The issuance costs associated with the liability component continues to be included in other assets on the Company’s consolidated balance sheets, whereas the issuance costs associated with the equity component are included in additional <font style="white-space: nowrap">paid-in-capital</font> and are not amortized. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The Company originally recorded amortization expense of note issuance costs of $3.2 million for 2006 and no amortization expense of note issuance costs in 2008 and 2007 due to the acceleration of the remaining amortization of note issuance costs in connection with the notice of acceleration relative to the 2010 Notes. The adoption of the FASB convertible debt accounting guidance resulted in the reversal of the acceleration of amortization of note issuance costs in 2006.

The adoption of the FASB convertible debt accounting guidance decreased the gain on extinguishment for 2008 to $2.5 million as a result of $1.6 million of accelerated interest expense, which was recorded against the original gain amount, and $0.3 million associated with the equity component. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The unamortized discount was amortized through January 2010 as the remaining $137.0 million in face value of the 2010 Notes were paid upon maturity on February 1, 2010.
