OVERVIEW

PLX Technology, Inc. ("PLX" or the "Company"), a Delaware corporation established in 1986, designs, develops, manufactures, and sells integrated circuits for interconnect applications. These interconnect products are a fundamental building block for standards-based subsystems. We market our products to major customers that sell electronic systems in the server, storage, communications, industrial, and consumer markets.

Products based on current serial interconnect technology standards such as PCI Express, USB, SATA, and Ethernet provide capabilities to customers that previous parallel technologies did not. They offer the ability for systems to scale in performance and capabilities, and allow for a standards-based building block approach that was not feasible in the past. As these serial technologies have become mainstream, we have been able to offer differentiated products based on standard ports that provide scalability and performance at a high-volume price point.

PLX is the market share leader in PCI Express switches and bridges. We recognized the trend towards this serial, switched interconnect technology early, launched products for this market long before our competitors, and have deployed multiple generations of products to serve a general-purpose, horizontal market. In addition to enabling customer differentiation through our product features, the breadth of our product offering is in itself a significant benefit to our customers, since we can serve the complete needs of our customers with cost-effective solutions tailored to the specific subsystem requirements. Our long experience with PCI Express connectivity products enables PLX to deliver reliable devices that operate under non-ideal real-world system environments.

PLX is building on our broad, general purpose interconnect success, and in particular our success in enterprise storage, by focusing on a rapidly growing vertical market: Consumer/Small Office Home Office (SOHO) storage. On January 2, 2009, we completed the acquisition of Oxford Semiconductor, Inc. (Oxford), a leading supplier of semiconductor components for the consumer and SOHO markets. Oxford has brought to market several generations of leadership products that allow storage customers to attach their disk subsystems directly to a computer through USB direct-attached storage (DAS), or to attach them through local area network-attached storage (NAS). We identified the shift from parallel to serial hard disk connectivity early, and benefited from this trend to be become the leader in high performance consumer/SOHO storage connectivity. Our products provide a rich variety of connectivity options, including USB, SATA, eSATA, FireWire, and Ethernet, and offer capabilities such as RAID and data encryption at industry leading performance levels.

PLX offers a complete solution consisting of semiconductor devices, software development kits, hardware design kits, operating system ports, and firmware solutions that enable added-value features in our products. We differentiate our products by offering higher performance and lower power, and by enabling a richer customer experience based on proprietary features that enable system-level customer advantages, and by providing capabilities that enable a customer to get to market more quickly.

We utilize a "fabless" semiconductor business model whereby we purchase wafers or packaged and tested semiconductor devices from independent manufacturing foundries. The advantage of this approach, in our opinion, allows us to focus on defining, developing and marketing our products and eliminates the need for us to invest large amounts of capital in manufacturing facilities and work-in-process inventory.

We rely on a combination of direct sales personnel, distributors and manufacturers' representatives throughout the world to sell a significant portion of our products. We pay manufacturers' representatives a commission on sales while we sell products to distributors at a discount from the selling price.

The time period between initial customer evaluation and design completion can range from six to twelve months or more. Furthermore, there is typically an additional six to twelve month or greater period after design completion before a customer orders volume production of our products. Due to the variability and length of these design cycles and variable demand from customers, we may experience significant fluctuations in new orders from month to month. In addition, we typically make inventory purchases prior to receiving customer orders. Consequently, if anticipated sales and shipments in any quarter do not occur when expected, expenses and inventory levels could be disproportionately high, and our results for that quarter and potentially future quarters would be materially and adversely affected.

Our long-term success will depend on our ability to successfully introduce new products. While new products typically generate little or no revenues during the first twelve months following their introduction, our revenues in subsequent periods depend upon these new products. Due to the lengthy sales cycle and additional time before our customers request volume production, significant revenues from our new products typically occur twelve to twenty-four months after product introduction. As a result, revenues from newly introduced products have, in the past, produced a small percentage of our total revenues in the year the product was introduced. See -"Our Lengthy Sales Cycle Can Result in Uncertainty and Delays with Regard to Our Expected Revenues" in Item 1A, Risk Factors, in Part II of this report on Form 10-Q.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 2009 AND MARCH 31,
2008

Net Revenues

The following table shows the revenue by product type (in thousands) and as a
percentage of net revenues:

                                  Three Months Ended
                                       March 31,

  Legacy products               $   7,078      $ 12,190
  As a percentage of revenues        43.0 %        53.6 %
  PCI Express products          $   6,195      $ 10,565
  As a percentage of revenues        37.6 %        46.4 %
  Storage products              $   3,184      $      -
  As a percentage of revenues        19.4 %           -

Net revenues consist of product revenues generated principally by sales of our semiconductor devices. Net revenues for the three months ended March 31, 2009 were $16.5 million, a decrease of 27.7% from $22.8 million for the same period in 2008. The decrease was due to lower sales as a result of the weakened global economy and economic uncertainty, partially offset by revenues generated from the Storage and Legacy products acquired as part of the Oxford acquisition.

For the three months ended March 31, 2009, sales to Excelpoint Systems Pte Ltd and Promate Electronics Co., Ltd accounted for 21% and 14%, respectively, of net revenues. For the same period in 2008, Excelpoint Systems Pte Ltd, Answer Technology, Inc. and Avnet, Inc. accounted for 30%, 12% and 12%, respectively, of net revenues. For both of these periods, no other individual direct customer or distributor represented greater than 10% of net revenues.

In the fourth quarter of 2008 and the first quarter of 2009 we experienced a broad decrease in order rates across most product lines, markets and end customers, and we expect second quarter of 2009 sales to modestly expand compared to the first quarter of 2009. Future demand for our products is uncertain and is highly dependant on general economic conditions and the demand for products that contain our chips. Customer demand for semiconductors can change quickly and unexpectedly. Our revenue levels have been highly dependent on the amount of new orders that are received for products to be delivered to the customer within the same quarter, also called "turns fill" orders. Because of the long cycle time to build our products and our lack of visibility into demand when turns fill orders are high, it is difficult to predict which products to build to match future demand. We believe the current high turns fill requirements will continue indefinitely. The high turns fill orders pattern, together with the uncertainty of product mix and pricing, makes it difficult to predict future levels of sales and profitability and may require us to carry higher levels of inventory.

Gross Margin

Gross margin represents net revenues less the cost of revenues. Cost of revenues includes the cost of (1) purchasing semiconductor devices or wafers from our independent foundries, (2) package, assembly and test services from our independent foundries, assembly contractors and test contractors and (3) our operating costs associated with the procurement, storage, and shipment of products as allocated to production.

Three Months Ended
March 31,
2009 2008
in thousands
Gross profit $ 8,946 $ 13,843
Gross margin 54.4 % 60.8 %

Gross margin for the three months ended March 31, 2009 decreased by 35.4% compared to the same period in 2008. The decrease was primarily due to the lower margins of the products acquired in the Oxford acquisition as well as overall product mix. The Oxford product margin was lower than expected as a result of an unplanned increase in demand of one of the Storage products.

Future gross profit and gross margin are highly dependent on the product and customer mix, provisions and recoveries of excess or obsolete inventory, the position of our products in their respective life cycles and specific manufacturing costs. Accordingly, we are not able to predict future gross profit levels or gross margins with certainty.

Research and Development Expenses

Research and development ("R&D") expenses consist primarily of tape-out costs at
our independent foundries, salaries and related costs, including share-based
compensation and expenses for outside engineering consultants.

                                 Three Months Ended
                                      March 31,
                                  2009          2008
                                    in thousands
 R&D expenses                  $    7,903      $ 6,498
 As a percentage of revenues         48.0 %       28.6 %

R&D expenses increased by $1.4 million or 21.6% in the three months ended March 31, 2009 compared to the same period in 2008. The increase in R&D in absolute dollars and as a percentage of revenue is due primarily to increases in R&D spending on compensation and benefit expenses of $0.8 million, engineering tools of $0.6 million and tape-out related costs of $0.4 million related to new activities assumed as a result of the acquisition of Oxford, partially offset by the decrease in share-based compensation expenses of $0.4 million.

We believe continued spending on research and development to develop new products is critical to our success. While we expect to achieve synergies after the integration of Oxford, R&D expenses in the second quarter of 2009 are expected to increase due to significant stock compensation costs related to our tender offer. Refer to Note 2 for additional information on the tender offer. We anticipate that R&D expenses over time will fluctuate due to the timing of projects and tape-out related activities.

Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses consist primarily of
salaries and related costs, including share-based compensation, commissions to
manufactures' representatives and professional fees, as well as trade show and
other promotional expenses.

                                 Three Months Ended
                                      March 31,

                                    in thousands
 SG&A expenses                 $    6,895      $ 6,453
 As a percentage of revenues         41.9 %       28.4 %

SG&A expenses increased by $0.4 million or 6.9% in the three months ended March 31, 2009 compared to the same period in 2008. The increase in SG&A in absolute dollars and as a percentage is due primarily to increased salaries and related costs associated to the acquisition of Oxford.

While we expect SG&A expenses in absolute dollars to decrease modestly in future periods as synergies are achieved after the integration of Oxford, SG&A expenses in the second quarter of 2009 are expected to increase due to significant stock compensation costs related to our tender offer. Refer to Note 2 for additional information on the tender offer.

Acquisition Related Costs

                    $      2,630       $   -

During the three months ended March 31, 2009 we recorded $2.6 million in acquisition related costs associated with the January 2, 2009 acquisition of Oxford. Deal costs related primarily to outside legal costs. Severance costs were the result of layoffs due to the redundancy issue that arose as a result of the acquisition. In addition, we acquired a building lease in Milpitas, California which was vacated upon acquisition. As a result, we took an impairment charge of the operating lease. See Note 10 of the condensed consolidated financial statements for additional information.

Amortization of Acquired Intangible Assets

Amortization of acquired intangible assets consists of amortization expense
related to developed core technology, tradename and customer base acquired as a
result of the Oxford acquisition in January 2009 and the developed core
technology acquired in the HiNT Corporation acquisition in May 2003 and NetChip
Technology, Inc. acquisition in May 2004.

                                                 Three Months Ended

                                                    in thousands

Amortization of acquired intangible increased by $0.6 million or 254.4% in the three months ended March 31, 2009 compared to the same period in 2008. The 2008 amortization expense related to intangibles acquired in our prior acquisitions of HiNT and NetChip. The increase is due to the developed core technology, tradename and customer base acquired as a result of the acquisition of Oxford. See Note 8 to our condensed consolidated financial statements for additional information.

Interest Income and Other, Net

                      Three Months Ended
                           March 31,
                       2009           2008
                         in thousands
 Interest income    $      245       $  482

                    $       48       $  488

Interest income reflects interest earned on cash, cash equivalents and short-term and long-term investment balances. Interest income for the three months ended March 31, 2009 decreased by $0.2 million or 49.2%, compared to the same period in 2008. The decrease was primarily due to lower cash and investment balances and interest rate fluctuations.

Interest expense of $0.3 million for the three months ended March 31, 2009 primarily consisted of interest recorded on the $14.2 million note associated with the acquisition of Oxford. We did not record interest expense for the same period in 2008.

Other income includes foreign currency translation gains and losses and other miscellaneous transactions. Other income may fluctuate significantly but we do not expect it to have material impact on our consolidated statements of operations.

Loss on Fair Value Remeasurement of Contingently Convertible Note Payable

As a part of the consideration for the Oxford acquisition, we recorded a liability for the contingent consideration due which, was recorded at fair value as of the acquisition date. Under FAS 141(R), we are required to remeasure the liability to fair value until the contingency is resolved and record the change in fair value in earnings. The fair value of the note payable was based on 3.4 million shares with a stock price of $1.82, or $6.2 million. As of March 31, 2009, the closing stock price was $2.17, or $7.4 million. The loss on the fair value of the note remeasurement is the increase in fair value of the liability of $1.2 million. See Note 7 of the condensed consolidated financial statements for additional information on the contingent consideration arrangement.

Provision for Income Taxes

Income tax expense of $19,000 has been recorded for the three month period ended March 31, 2009, compared to provision of $77,000 for the same period in 2008. Income tax expense for the three months ended March 31, 2009 was a result of applying the estimated annual effective tax rate to cumulative loss before taxes adjusted for certain discrete items which are fully recognized in the period they occur. For the same period in 2008, the income tax expense was a result of applying the estimated annual effective tax rate to cumulative income before taxes adjusted for certain discrete items which are fully recognized in the period they occur.

We have determined that negative evidence supports the need for a full valuation allowance against our net deferred tax assets at this time. We will maintain a full valuation allowance until sufficient positive evidence exists to support a reversal of the valuation allowance.

We adopted FIN 48, regarding accounting for uncertain tax benefits, at the beginning of calendar year 2007. As of March 31, 2009, we have unrecognized tax benefits of approximately $2.2 million of which none, if recognized, would result in a reduction of our effective tax rate. There were no material changes in the amount of unrecognized tax benefits during the three months ended March 31, 2009. Future changes in the remaining balance of unrecognized tax benefits will have no impact on the effective tax rate as they are subject to a full valuation allowance. We do not expect that the amount of our unrecognized tax benefits will significantly change within the next twelve months.

We are subject to taxation in the United States and various states and foreign jurisdictions. The tax years 1998 through 2008 remain open to examination by the federal and most state tax authorities due to certain acquired net operating loss and overall credit carryforward positions.

Liquidity and Capital Resources

In summary, our cash flows were (in thousands):

                                                                  Three Months Ended
                                                                      March 31,
                                                                  2009          2008

We invest excess cash predominantly in debt instruments that are highly liquid, of high-quality investment grade, and predominantly have maturities of less than one year with the intent to make such funds readily available for operating purposes. As of March 31, 2009 cash, cash equivalents, short and long-term marketable securities were $41.6 million, a decrease of $5.5 million from $47.1 million at December 31, 2008.

Cash provided by (used in) operating activities primarily consists of net income
(loss) adjusted for certain non-cash items including depreciation, amortization, share-based compensation expense, impairments, fair value remeasurements, provisions for excess and obsolete inventories, changes in pre-acquisition deferred tax balances, other non-cash items, and the effect of changes in working capital and other activities. Cash used in operating activities for the three months ended March 31, 2009 of $9.4 million consisted primarily of net loss of $10.5 million adjusted for non-cash items of $3.2, decreases in accounts payable of $1.9 million, accrued compensation and benefits of $1.3 million and other accrued expenses and liabilities of $0.8 million and an increase in other assets of $0.8 million due to an increase in software an IP licenses, partially offset by a decreases in inventory of $2.9 million and accounts receivable of $0.4 million. Cash provided by operating activities for the three months ended March 31, 2008 of $2.2 million consisted primarily of net income of $1.1 million adjusted for non-cash items of $1.5 million partially offset by increases in accounts receivable of $0.3 million and other assets of $0.3 million.

Cash provided by investing activities for the three months ended March 31, 2009 of $10.1 million was primarily due to the sales and maturities of investments (net of purchases of investments) of $6.0 million and cash acquired through the acquisition of Oxford of $4.4 million. Cash used in investing activities for the three months ended March 31, 2008 of $3.3 million was due to purchases of marketable securities (net of sales and maturities of investments) of $2.3 million and capital expenditures of $0.9 million. Capital expenditures have generally been comprised of purchases of engineering equipment, computer hardware, software, server equipment and furniture and fixtures.

Cash used in financing activities for the three months ended March 31, 2009 of $0.1 million was due to the payments made on capital lease obligations. Cash used in financing activities for the three months ended March 31, 2008 of $3.9 million was due to common stock repurchases.

The negative effect of exchange rates on cash and cash equivalents for the three months ended March 31, 2009 and 2008 was due to the weakening of the U.S. dollar against other foreign currencies.

As of March 31, 2009, we had the following significant contractual obligations and commercial commitments (in thousands):

                                                                   Payments due in

As a part of the Oxford acquisition Merger Agreement, we acquired all of the outstanding shares of capital stock of Oxford in exchange for 5,600,000 shares of common stock of PLX and a promissory note in the principal amount of $14,200,000 (the "Note") that will be satisfied by either (i) the issuance of an additional 3,400,000 shares of common stock of PLX upon approval of PLX's stockholders, or (ii) the repayment of the principal amount of the Note if such stockholder approval is not obtained by June 30, 2009. Interest at the rate of 6% per annum, or approximately $0.3 million, is payable in cash whether the principal balance is satisfied in cash or in shares of our common stock.

We believe that our existing resources, together with cash generated from our operations will be sufficient to meet our capital requirements for at least the next twelve months. Our future capital requirements will depend on many factors, including the inventory levels we maintain, the level of investment we make in new technologies and improvements to existing technologies and the levels of monthly expenses required to launch new products. From time to time, we may also evaluate potential acquisitions and equity investments complementary to our technologies and market strategies. To the extent that existing resources and future earnings are insufficient to fund our future activities, we may need to raise additional funds through public or private financings. Additional funds may not be available or, if available, we may not be able to obtain them on terms favorable to us and our stockholders.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, . . .
