NOTES TO UNAUDITED FINANCIAL STATEMENTS

March 31, 2009

1. BASIS OF PRESENTATION

Interim financial data

The accompanying unaudited financial
statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 for Regulation S-X.
Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements and should be read in conjunction with the Companys annual report
filed on Form 10-K for the fiscal year ended December 31, 2008. In the opinion of management, all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for a fair presentation of the results of
operations have been included. Operating results for the three month period ended March 31, 2009 are not necessarily indicative of results that may be expected for the year ending December 31, 2009.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Investments

The Company invests available cash primarily in investment grade commercial paper, corporate notes and government securities. While the Companys
investment policy no longer includes auction-rate securities as an approved investment, the Company continues to hold auction rate securities purchased prior to the policy change. The Company also holds put options associated with an agreement with
UBS, AG (see Auction-rate securities put options below). Investments classified as available-for-sale securities are carried at fair market value with unrealized gains and losses recorded in accumulated other comprehensive income (loss).
Investments in trading securities are reported at fair value, with both realized and unrealized gains and losses recorded in other income (expense), net in the Statement of Operations. Investments in which the Company has the ability and intent, if
necessary, to liquidate in order to support its current operations, are classified as short-term. The Companys long-term investments consist primarily of auction-rate securities and put options.

The Company reviews its available-for-sale securities investments at the end of each quarter for other-than-temporary declines in fair value based on the specific
identification method. The Company considers various factors in determining whether an impairment is other-than-temporary, including the severity and duration of the impairment, changes in underlying credit ratings, forecasted recovery, its ability
and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. When the Company concludes that an
other- than-temporary impairment has resulted, the difference between the fair value and carrying value is written off and recorded as a charge on the Statement of Operations.

Auction-rate securities put options (ARS Put Options)

In October 2008, the Company entered into an
agreement that provides the Company with the right, but not the obligation, to sell all its auction-rate securities to UBS, AG for par value during the period of June 30, 2010 to July 2, 2012. The ARS Put Options will provide the Company
with the opportunity to recover the estimated unrealized loss on its ARS investments. The Company recorded the fair value of the ARS Put Options upon receipt and included it in other long-term assets at March 31, 2009 and December 31,
2008. In accordance with SFAS No. 159, The Fair Value Option for Financial Assets and Financial LiabilitiesIncluding an Amendment of SFAS No. 115 (SFAS No. 159), which was adopted by the Company on
January 1, 2008, the Company elected fair value accounting for the ARS Put Options. Unrealized gains and losses related to the ARS Put Options will be recognized in earnings. See Note 4Investments for additional information regarding the
ARS Put Options.

Treasury Stock

The Company records
treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock.

Inventories

Inventories are valued at the lower of cost or market. Cost is determined using the first-in, first-out method, and includes materials, labor and overhead. The Company reduces the carrying value of its inventories for differences between
the cost and the estimated net realizable value, taking into account usage, expected demand, technological obsolescence and other information. Inventories are composed of the following:

Revenue recognition

The Company recognizes revenue from product sales when earned in accordance with Staff Accounting Bulletin (SAB) No. 104, Revenue Recognition. Revenue is recognized when, and if, evidence of an
arrangement is obtained and the other criteria to support revenue recognition are met, including:



| |  | Persuasive evidence of an arrangement exists. The Company requires evidence of a purchase order with the customer specifying the terms and
specifications of the product to be delivered, typically in the form of a signed quotation or purchase order from the customer.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Title has passed and the product has been delivered. Title passage and product delivery generally occur when the product is delivered to a common
carrier.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The price is fixed or determinable. All terms are fixed in the signed quotation or purchase order received from the customer. The purchase orders do not
contain rights of cancellation, return, exchange or refund.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Collection of the resulting receivable is reasonably assured. The Companys standard arrangement with customers includes 30 day payment terms.
Customers are subject to a credit review process that evaluates the customers financial position and their ability to pay. Collectability is determined by considering the length of time the customer has been in business and history of
collections. If it is determined that collection is not probable, no product is shipped and no revenue is recognized unless cash is received in advance.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company does not provide maintenance or other services and it does not have sales that involve multiple elements or deliverables as defined under Emerging Issues Task Force Issue (EITF) No. 00-21,
Revenue Arrangements with Multiple Deliverables.

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of
common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average number of dilutive common shares outstanding during the period. Dilutive shares outstanding are calculated by adding
to the weighted shares outstanding any common stock equivalents from outstanding stock options and warrants based on the treasury stock method.

Diluted
net loss per share is the same as basic net loss per share for the three months ended March 31, 2009 because the effects of potentially dilutive securities are anti-dilutive.

At March 31, 2009 the Company had the following anti-dilutive securities outstanding which were excluded from the calculation of diluted net loss per share:

Recent Accounting Pronouncements

On January 1, 2009 the Company adopted FASB Staff Position FAS 157-2, Effective Date of FASB Statement No. 157, which had delayed the effective date of SFAS 157 for nonfinancial assets and
nonfinancial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), to fiscal years beginning after November 15, 2008. The adoption of FSP FAS 157-2 did
not have a material impact on the Companys financial position or results of operations.

In April 2009, the FASB issued FSP FAS 107-1 and APB 28-1,
Interim Disclosures about Fair Value of Financial Instruments. This FASB Staff Position (FSP) amends Statement of Financial Accounting Standards (SFAS) No. 107, Disclosures About Fair Value of Financial
Instruments, to require disclosures about fair value of financial instruments for interim reporting periods of publicly traded companies as well as in annual financial statements. This FSP also amends APB Opinion No. 28, Interim
Financial Reporting, to require those disclosures in summarized financial information at interim reporting periods. This FSP is effective for interim reporting periods ending after June 15, 2009, with early adoption permitted for periods
ending after March 15, 2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial adoption, this FSP requires comparative purposes at initial adoption. In
periods after initial adoption, this FSP requires comparative disclosures only for periods ending after initial adoption. The Company does not expect the changes associated with adoption of this FSP will have a material effect on the determination
or reporting of the Companys financial results.

In April 2009, the FASB issued FSP FAS 115-2 and FAS 124-2, Recognition and Presentation of
Other-Than-Temporary Impairments. This FSP amends the other-than-temporary impairment guidance for debt securities to make the guidance more operational and to improve the presentation and disclosure of other-than-temporary impairments on debt
and equity securities in the financial statements. This FSP does not amend existing recognition and measurement guidance related to other-than-temporary impairments of equity securities. This FSP is effective for interim and annual reporting periods
ending after June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial
adoption, this FSP requires comparative disclosures only for periods ending after initial adoption. The Company does not expect the changes associated with adoption of this FSP will have a material effect on the determination or reporting of the
Companys financial results.

In April 2009, the FASB issued FSP FAS 157-4, Determining Fair Value When the Volume and level of Activity for the
Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly. This FSP provides additional guidance for estimating fair value in accordance with SFAS No. 157, Fair Value Measurements, when
the volume and level of activity for the asset or liability have significantly decreased. This FSP also includes guidance on identifying circumstances that indicate a transaction is not orderly. This FSP is effective for interim and annual reporting
periods ending after June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after
initial adoption, this FSP requires comparative disclosures only for periods ending after initial adoption. The Company does not expect the changes associated with the adoption of this FSP will have a material effect on the determination or
reporting of the Companys financial results.

Effective January 1, 2009, the Company implemented SFAS No. 157, Fair Value
Measurements, for our nonfinancial assets and liabilities that are remeasured at fair value on a non-recurring basis. See Note 4 for disclosures associated with adoption of this standard.

3. SEGMENT INFORMATION

The Company has determined that it operates
in only one segment in accordance with SFAS No. 131, Disclosures About Segments of an Enterprise and Related Information, as it only reports profit and loss information on an aggregate basis to its chief operating decision
maker.

4. INVESTMENTS

The Company invests available cash primarily in investment grade commercial paper, corporate notes and government securities. The Companys short-term investments balance of $33.8 million as of March 31, 2009, is comprised of US
Treasury securities of $23.1 million, corporate notes and bonds of $9.0 million and commercial paper of $1.7 million. The Companys short-term investments are classified as available-for-sale securities and are carried at fair market value with
unrealized gains and losses recorded in accumulated other comprehensive income (loss).

While the Companys investment policy no longer includes
auction-rate securities as an approved investment, the Company continues to hold auction-rate securities purchased prior to the policy change. In February 2008, the Company began experiencing failed auctions of its entire auction-rate securities
portfolio, resulting in its inability to sell these securities in the short term. All of these auction-rate securities are AAA rated by one or more of the major credit rating agencies and have contractual maturities from 2036 to 2045. Further, all
of these securities are collateralized by student loans, and approximately 99% of the collateral qualifies under the Federal Family Education Loan Program and is guaranteed by the US government. The Company is receiving the underlying cash flows on
all its auction-rate securities. The Company is unable to predict if these funds will become available before their maturity dates. As such, the auction-rate securities have been classified as long-term investments as of March 31, 2009. The Company
also holds put options associated with an agreement with UBS, AG related to the auction-rate securities purchased through them. The Companys long-term investments consist of a $2.0 million investment in Peregrine Semiconductor, Corp. (a
customer) Series D-1 Preferred shares and $10.7 million of auction-rate securities and put options. Long-term investments are trading securities recorded at fair value and unrealized gains and losses are reported as part of realized gain (loss).

As noted above, in October 2008 the Company entered into an agreement with UBS, AG, which provides the Company certain
rights to sell to UBS, AG the auction-rate securities that were purchased through them. As of March 31, 2009, the Company held $10.8 million par value auction-rate securities purchased from UBS, AG. The Company has the option to sell these
securities to UBS, AG at par value from June 10, 2010 through July 2, 2012. UBS, AG, at its discretion, may purchase or sell these securities on the Companys behalf at any time provided the Company receives par value for the
securities sold. The issuers of the auction-rate securities continue to have the right to redeem the securities at their discretion. The agreement also permits the Company to establish a demand revolving credit line in an amount equal to the par
value of the securities at a net no cost. If the Companys debt is determined to be rated below investment grade or is not rated, the amount that can be borrowed is limited to 75% of the market value of the auction-rate securities. As of
March 31, 2009, the Company had no loans outstanding under this agreement.

The Companys right to sell the auction-rate securities to UBS, AG,
commencing on June 10, 2010 represents put options for a payment equal to the par value of the auction-rate securities. The Company elected the fair value option under SFAS 159 and recorded the put options in long term investments.
During the three months ended March 31, 2009, the Company recorded a loss of $505,463 representing the changes in fair value of the put options. The Company also recorded a gain of $518,934 representing the changes in fair value of the
auction-rate securities. Both the gain and loss from recording the change in fair value of the put options and auction-rate securities were recorded in realized gain (loss).

The Company values the auction-rate securities and put options using a discounted cash model that weights various factors including interest rates and expected holding period. The investment in Peregrine
Semiconductor, Corp. (Peregrine) is valued at a pre-money valuation of Peregrine as determined by an investor group in the fourth quarter of 2008 and is adjusted as needed based on a review of Peregrines financial position. The Company
believes this is a fair value of these investments at March 31, 2009.

The following table presents the amortized cost and gross unrealized gains and
losses on all securities at March 31, 2009:

Effective January 1, 2008, the Company adopted Statement of Financial Accounting Standards (SFAS)
No. 157, Fair Value Measurements (SFAS No. 157). In February 2008, the Financial Accounting Standards Board (FASB) issued FASB Staff Position No. FAS 1572, Effective Date of FASB Statement
No. 157, which provides a one year deferral of the effective date of SFAS 157 for non-financial assets and non-financial liabilities, except those that are recognized or disclosed in the financial statements at fair value at least
annually. Therefore, the Company has adopted the provisions of SFAS No. 157 with respect to its financial assets and liabilities only. SFAS No. 157 defines fair value, establishes a framework for measuring fair value under generally

accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined under SFAS No. 157 as the price that would
be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques
used to measure fair value under SFAS No. 157 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are
considered observable and the last unobservable, that may be used to measure fair value which are the following:



| |  |  | Level 1Quoted prices in active markets for identical assets or liabilities.
| | - |  | ----------------------------------------------------------------------------



| |  |  | Level 2Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in
markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Level 3 assets consist of AAA-rated municipal bonds with an auction reset feature (auction-rate securities) whose
underlying assets are generally student loans which are substantially backed by the federal government, auction-rate security put options and Peregrine Semiconductor, Corp Series D-1 Preferred shares. As of March 31, 2009, due to the auction
failures, underlying maturities of the auction-rate securities of greater than one year and the Companys ability to hold the securities beyond one year, the Company classified its investment in auction-rate securities as long-term investments.
These investments were valued at fair value as of March 31, 2009. The following table provides a summary of changes in fair value of the Companys Level 3 financial assets as of March 31, 2009:

In addition to the debt securities noted above, the Company had approximately $386,000 of time deposits included in cash
and cash equivalents as of March 31, 2009.

5. RELATED PARTY TRANSACTIONS

In November 2008, the Company purchased 1,345,444 shares for a total of $2.0 million of Peregrine Semiconductor, Corp. Series D-1 Preferred shares, which represents less than 1% of shares outstanding. The terms and
stock price of the purchase were the same as for the other investors who participated. Peregrine Semiconductor, Corp. is a customer of the Company. For the three months ended March 31, 2009, revenue and accounts receivable from Peregrine
Semiconductor, Corp were $444,750. The pricing terms and conditions of the sales to Peregrine are similar to those available to the Companys other non-related customers.

6. SIGNIFICANT CUSTOMERS

For the three months ended March 31, 2009, the Company had three customers that
accounted for 34%, 19% and 14% of its revenue and for the three months ended March 31, 2008, the Company had four customers that accounted for approximately 30%, 16%, 15% and 11% of its revenue.

Customers individually representing more than 10% of trade receivables accounted for approximately 64% and 61% of accounts receivable as of March 31, 2009 and
December 31, 2008, respectively. The Company grants credit to customers based on an evaluation of their financial condition. Losses from credit sales are provided for in the financial statements.

7. STOCKHOLDERS EQUITY

Common Stock

As of March 31, 2009, the Company had 85,000,000 shares of common stock authorized with a par value of $0.001 and the Company had reserved 1,917,743 shares of common
stock for issuance upon the exercise of outstanding common stock options. Also, 1,305,766 shares of the Companys common stock were reserved for future grants of stock options (or other similar equity instruments) under the Companys 2001
Equity Plan (the 2001 Plan) and 2007 Stock Incentive Plan (the 2007 Plan) as of March 31, 2009. In addition, 336,705 shares of the Companys common stock were reserved for future exercise of outstanding warrants as
of March 31, 2009.

Warrants

For the three months
ended March 31, 2009, no common stock warrants were exercised. At March 31, 2009 and December 31, 2008, there were 336,705 common stock warrants outstanding.

Treasury Stock

In November 2008, the Company authorized a stock repurchase program to purchase up to $15.0 million
of common stock over a period of two years. The stock repurchase program authorizes the Company to repurchase shares of its common stock in the open market at times and prices considered appropriate by the Company depending upon prevailing market
conditions and other corporate considerations. The treasury shares are accounted for using the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. For the three months ended March 31, 2009, the Company
repurchased 519,242 shares at an average price of $4.96 for $2.6 million.

8. STOCK INCENTIVE PLANS

The Company sponsors a stock option plan, the 2001 Plan, which allows for the grant of incentive and nonqualified stock options for the purchase of common stock. Each
option entitles the holder to purchase one share of common stock at the specified option exercise price. The exercise price of each incentive stock option granted must not be less than the fair market value on the grant date. At the discretion of
management and with the approval of the Board of Directors, the Company may grant options under the 2001 Plan. Management and the Board of Directors determine vesting periods and expiration dates at the time of the grant.

##### Table of Contents

In August 2007, the Company adopted the 2007 Plan, which allows for the grant of incentive stock options, non-statutory
stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards and bonus shares. The maximum number of shares which may be awarded or sold under the 2007 Plan is 2,307,692 shares. The Board of Directors
appoints a committee to administer the plan. The plan committee determines the type of award to be granted, the fair market value, the number of shares covered by the award, and the time when the award vests and may be exercised.

Upon the adoption of SFAS 123R, the Company began using the Black-Scholes option pricing model to value stock options. The Company uses historical stock prices of
companies which it considers as a peer group as the basis for its volatility assumptions. The assumed risk-free rates were based on US Treasury rates in effect at the time of grant with a term consistent with the expected option lives. The expected
term is based upon the vesting term of the Companys options, a review of a peer group of companies, and expected exercise behavior. The forfeiture rate is based on past history of forfeited options. The expense is being allocated using the
straight-line method. For the three months ended March 31, 2009 and 2008, the Company recorded $162,302 and $165,560, respectively, of stock compensation expense related to the adoption of SFAS 123R. As of March 31, 2009, the Company has
$3,076,301 of total unrecognized compensation cost related to nonvested awards granted under the Companys stock-based plans that it expects to recognize over a weighted-average period of 3.05 years. Under the prospective method of adoption of
SFAS 123R, the Company continues to account for options issued prior to January 1, 2006 under the intrinsic value method of APB 25.

The fair value per share of options granted for the three months ended March 31, 2009 was $4.01 and the fair
value of each option grant was estimated at the date of grant using the Black-Scholes option-pricing model using an expected term of 5.2 years, risk-free interest rate of 1.41%, expected volatility of 50% and no dividend yield. The Company used an
expected forfeiture rate of 30.39%.

For the three months ended March 31, 2009 and 2008, the Company recorded $28,499 and $22,574, respectively, of
stock compensation expense related to restricted stock.

|ITEM 2. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION
|------- | ------------------------------------------------------------------------------------

All statements, other than statements of historical facts, included in this Quarterly Report on Form 10-Q regarding our estimates, expectations, beliefs, intentions, projections or strategies for the future, results
of operations, financial position, net sales, projected costs, prospects and plans and objectives of management for future operations may be forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995.
We have based these forward-looking statements on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and
long-term business operations and objectives and financial needs. These forward looking statements can be identified by the use of terms and phrases such as believe, plan, intend, anticipate,
target, estimate, expect, and the like, and/or future-tense or conditional constructions such as will, may, could, should, etc. (or the negative thereof). Items
contemplating or making assumptions about actual or potential future sales, market size and trends or operating results also constitute forward-looking statements.

Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the
extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Before investing in our common stock, investors should be aware that the
occurrence of the risks, uncertainties and events described in the section entitled Risk factors in our Annual Report on Form 10-K and elsewhere in this Quarterly Report could have a material adverse effect on our business, results of
operations and financial condition.

Although we believe that the expectations reflected in the forward-looking statements are reasonable, forward-looking
statements are inherently subject to known and unknown business, economic and other risks and uncertainties that may cause actual results to be materially different from those discussed in these forward-looking statements. Readers are urged not to
place undue reliance on these forward-looking statements, which speak only as of the date of this Quarterly Report. We assume no obligation to update any forward-looking statements in order to reflect any event or circumstance that may arise after
the date of this Quarterly Report, other than as may be required by applicable law or regulation. If one or more of these risks or uncertainties materialize, or if the underlying assumptions prove incorrect, our actual results may vary materially
from those expected or projected.

You should read this Quarterly Report, the documents that we reference in this Quarterly Report and have filed with the
SEC as exhibits and our Annual Report on Form 10-K for the year ended December 31, 2008 with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we
expect.

Unless otherwise indicated, the terms Rubicon, the Company, we, us, and our refer to
Rubicon Technology, Inc.

OVERVIEW

We are an advanced
electronic materials provider that develops, manufactures and sells monocrystalline sapphire and other innovative crystalline products for Light-Emitting Diodes (LEDs), radio frequency integrated circuits (RFICs), blue laser
diodes, optoelectronics and other optical applications. The emergence of sapphire in commercial volumes at competitive prices has enabled the development of new technologies such as high brightness (HB) white, blue and green LEDs and
highly-integrated RFICs. We apply our proprietary crystal growth technology to produce high-quality sapphire products efficiently to supply our end-markets, and we work closely with our customers to meet their quality and delivery needs.

We are a vertically-integrated manufacturer of high-quality sapphire substrates and optical windows that are used in a variety of high-growth, high-volume end-market
applications. Our largest product line is two inch to four inch sapphire wafers for use in LEDs and blue laser diodes for solid state lighting and electronic applications. In addition, we sell six inch sapphire wafers that are used for
Silicon-on-Sapphire (SOS) RFICs, as well as products for military, aerospace, sensor and other applications. We have also extended our technology to manufacture eight inch products to support next-generation LED, RFIC and optical window
applications and are developing the capability to produce even larger products.

Our revenue consists of sales of sapphire materials sold in core, as-cut,
as-ground and polished forms in two, three, four and six inch diameters as well as optical materials sold as blanks or polished windows. Products are made to varying specifications, such as crystal planar orientations and thicknesses.

Historically, a significant portion of our revenue has been derived from sales to relatively few customers. For the three months ended March 31, 2009, we had three
customers that accounted for approximately 34%, 19% and 14% of our revenue and for the three months ended March 31, 2008, we had four customers that accounted for approximately for 30%, 16%, 15% and 11% of our revenue. Other than as discussed
above, none of our customers accounted for more than 10% of our revenue for such periods. Although we are attempting to diversify and expand our customer base, we expect our revenue to continue to be concentrated among a small number of customers.
We expect that our significant customers may change from period to period.

##### Table of Contents

We recognize revenue upon shipment to our customers. We derive a significant portion of our revenue from customers
outside of the United States. The majority of our sales are to the Asian market and we expect that region to continue to be a major source of revenue for us. All of our revenue is denominated in US dollars. The current economic crisis has resulted
in weak demand for LED and SOS products, which has significantly reduced orders and sale of our sapphire substrates. We anticipate that reduced demand for our products will continue at least through mid-2009. As a result, our manufacturing
facilities are currently underutilized, which negatively impacts our gross margins.

Our cost of goods sold consists primarily of manufacturing materials,
labor, manufacturing-related overhead such as utilities, depreciation and rent, provisions for excess and obsolete inventory reserves, freight and warranties. We manufacture our products at our Franklin Park, Illinois and Bensenville, Illinois
manufacturing facilities based on customer orders. We purchase materials and supplies to support such demand. We are subject to variations in the cost of raw materials and consumables from period to period because we do not have long-term
fixed-price agreements with our suppliers.

Our operating expenses are comprised of sales and marketing, research and development (R&D),
and general and administrative expenses (G&A). G&A expenses consist primarily of salaries and associated costs for employees in finance, human resources, information technology and administrative activities, charges for
accounting, legal, and insurance fees, and stock-based compensation under Statement of Financial Accounting Standards No. 123(R), Share-Based Payment (SFAS 123R). The majority of our stock-based compensation relates to
administrative personnel and is accounted for as a general and administrative expense.

Other income (expense) consists of interest income and expense and
realized gains and losses on investments. For the three months ended March 31, 2008, interest expense was $2,000. We repaid most of our outstanding indebtedness with a portion of the proceeds from our IPO in November 2007 and repaid the
remainder in February 2008. We do not expect to incur interest expense for the next twelve months. Proceeds from our IPO were invested in available-for-sale and trading securities.

We account for income taxes under the asset and liability method whereby the expected future tax consequences of temporary differences between the book value and the tax basis of assets and liabilities are recognized
as deferred tax assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to be recognized. A full valuation allowance is provided as management cannot conclude that it is more likely than not that
our deferred tax assets will be realized. At March 31, 2009, we had approximately $42 million in net operating loss carryforwards (NOLs). We believe that we are not restricted in our ability to use the full amount of the NOLs, nor
is there a limit to the amount of NOLs that may be used in any given year.

Because of the current economic environment, it is difficult to predict capital
expenditures needed to support or enhance our current operations, but we anticipate it will be approximately $10.0 million in 2009. These expenditures will be primarily focused on research and development and cost savings initiations and will be
incurred mostly in the second half of 2009. Our capital expenditures in the first quarter 2009 were $525,000.

Revenue. Revenue was $2.3 million for the three months ended March 31, 2009 and $10.5 million for
the three months ended March 31, 2008, a decrease of $8.2 million. We experienced a significant decrease in revenue across all product lines and diameters. The impact of the worldwide economic crisis resulted in excess inventory throughout the
LED supply chain which significantly reduced orders. Core and as-cut quantities shipped for the three months ended March 31, 2009 decreased by 90% which resulted in lower revenue of $5.0 million. In addition, the SOS RFIC business is largely
dependent upon the consumer electronics market which also had a significant downturn. Consequently, SOS RFIC revenue decreased by $2.4 million. Also, lower demand has resulted in lower pricing which decreased substrate revenue by $250,000. We expect
pricing pressure on new orders to continue in 2009 until demand for sapphire substrates improves. We had lower contract research revenue of $250,000 as we completed our contract for the development of eight inch wafers in the third quarter 2008. We
also had lower revenue of $302,000 from optical products due to decreased sales of sapphire and fluorides for military, sensor and instrumentation applications. For the remainder of 2009, for us to achieve higher volumes of sapphire wafer sales,
inventories in the LED and SOS RFIC industries need to be consumed. Our customers, particularly those in Taiwan, are beginning to see some improvement in demand driven by an increasing rate of adoption of LED back-lit products, such as notebook
computers and LED back-lit LCD televisions. However, given our customers current inventory levels, we do not expect revenue streams to improve until the third quarter 2009.

Gross profit (loss). Gross loss was $2.6 million for the three months ended March 31, 2009 compared to a
gross profit of $3.9 million for the three months ended March 31, 2008, a decrease of $6.5 million. With the decrease in orders, we experienced lower utilization of equipment and staff which resulted in under absorbed manufacturing costs of
approximately $2.9 million. Also, gross profit was impacted by the decrease of $250,000 of direct contract revenue, which had little direct cost.

General and administrative expenses. G&A expenses were $1.1 million for the three months ended March 31, 2009 and $1.9 million for the three months ended March 31, 2008, a decrease of $800,000. The decrease was
primarily due to $398,000 from lower bonus costs due to no performance bonus anticipated for 2009, lower bad debt expense of $148,000 on collection of an over 90 day past due receivable, and $36,000 in lower recruiting costs. In addition, follow-on
public offering costs of $181,000 were incurred in 2008 but not in 2009.

Sales and marketing expenses. Sales and marketing expenses were
$243,000 for the three months ended March 31, 2009 and $235,000 for the three months ended March 31, 2008, an increase of $8,000. The increase in sales and marketing expenses is attributable to additional headcount, travel and marketing
and trade show expenses of $14,000 all in support of increased initiatives to help grow sales with new customers partially offset by a decrease in agent commission expense of $6,000 on lower sales and a phasing out of agents.

Research and development expenses. R&D expenses were $152,000 for the three months ended March 31, 2009 and $267,000 for the three months ended
March 31, 2008, a decrease of $115,000. The decrease was primarily attributable to a decrease in headcount expenses of $108,000 and a decrease in spending on research projects of $9,000. We have recently added two development engineers which
will increase R&D expenses for the remainder of 2009.

Other income (expense). Other income (expense) was $270,000 for the three months
ended March 31, 2009 and $858,000 for the three months ended March 31, 2008, a decrease in net other income of $588,000. The decrease was due to lower interest income of $603,000 as a result of lower investment principal and lower interest
rates.

LIQUIDITY AND CAPITAL RESOURCES

We
historically funded our operations using a combination of issuances of common stock and preferred stock, a working capital line of credit and term loans, and cash generated from our operations. Since our inception, we have raised approximately $136
million of equity from both private and public issuances of common and preferred stock.

As of March 31, 2009, we had cash and short term investments
totaling $39.4 million, including cash of $386,000 held in deposits at a major bank, $5.2 million invested in money market funds and short term investments in commercial paper, state and local bonds, and U.S. treasury securities of $33.8 million.
Our long term investments of $12.7 million are municipal auction-rate securities and related put options of $10.7 million and a $2.0 million investment in Peregrine Semiconductor, Corp. (one of our customers) Series D1 preferred stock. In February
2008, we began experiencing failed auctions of our entire auction-rate securities portfolio, resulting in our inability to sell these securities in the short term. All of the auction-rate securities are AAA rated by one or more of the major credit
rating agencies and have contractual maturities from 2036 to 2045. Further, all of these securities are collateralized by student loans, and approximately 99% of the collateral qualifies under the Federal Family Education Loan Program and is
guaranteed by the US government. We are receiving the underlying cash flows on all of our auction-rate securities. The auction-rate securities have been classified as long-term investments as of March 31, 2009.

In October 2008, we entered into an agreement with UBS, AG, which provides us with certain rights to sell to UBS, AG all of our auction-rate securities that were
purchased through them. We have the option to sell these securities to UBS, AG at par value from June 10, 2010 through July 2, 2012. UBS, AG, at its discretion, may purchase or sell these securities on our behalf at any time provided we
receive par value for the securities sold. The issuers of the auction-rate securities continue to have the right to redeem the securities at their discretion. The agreement also permits us to establish a demand revolving credit line in an amount
equal to the par value of the securities at a net no cost. If our debt is determined to be rated below investment grade or is not rated, the amount that can be borrowed is limited to 75% of the market value of the auction-rate securities. As of
March 31, 2009, we had no loans outstanding under this agreement.

Our right to sell the auction-rate securities to UBS, AG commencing on
June 10, 2010 represents put options for a payment equal to the par value of the auction-rate securities. We elected the fair value option under SFAS 159 and recorded the put options in long term investments. We do not expect to
need access to the auction-rate securities capital prior to the maturity of the auction-rate security put options.

Cash flows from operating activities

Cash used in operating activities was $2.4 million for the three months ended March 31, 2009. During such period, we generated a net loss of $3.9
million and we incurred non-cash expenses of $1.5 million, including depreciation and amortization expense of $1.3 million and stock-based compensation expense of $226,000. We experienced a decrease during such period in accounts receivable of

##### Table of Contents

$996,000 as sales declined, a decrease in accounts payable of $1.2 million as purchases declined and a decrease in spare parts of $678,000 primarily due to
not replenishing stock used due to lower production volumes. We also experienced a decrease in accrued payroll of $301,000 due to pay outs of bonuses earned in the first half of 2008 and a decrease in corporate income and franchise taxes of $183,000
due to payment of 2008 taxes due.

Cash provided by operating activities was $1.7 million for the three months ended March 31, 2008. During such
period, we generated net income of $2.3 million and we incurred non-cash expenses of $1.1 million, including depreciation and amortization expense of $945,000 and stock-based compensation expense of $188,000. We experienced an increase during such
period in accounts receivable of $928,000 on increased sales, an increase in accounts payable of $696,000 and an increase in spare parts of $448,000 due primarily to an increase in safety stock of raw material and furnace material inventory. We also
experienced a decrease in accrued payroll of $518,000 due to pay outs of bonuses earned in 2007 and a decrease in deferred revenue of $250,000 due to recognition of revenue deferred on a contract research project.

Cash flows from investing activities

Net cash provided by (used in)
investing activities was $2.8 million and ($1.8) million for the three months ended March 31, 2009 and 2008, respectively. During the three months ended March 31, 2009, we used approximately $456,000 to add crystal growth furnaces and
approximately $57,000 to upgrade existing capacity in other areas. This was partially offset by sales of investments of $3.4 million which were used to fund operations, capital spending and our stock repurchases. During the three months ended
March 31, 2008, we used approximately $3.1 million to purchase components used to construct additional crystal growth furnaces, approximately $488,000 for infrastructure changes needed to commence operations in our facility in Bensenville,
Illinois and approximately $1.1 million to purchase various equipment used to expand our production capacity in support of our sales growth. This was partially offset by sales of investments of $2.8 million. Because of the current economic
environment, it is difficult to predict capital expenditures needed to support or enhance our current operations, but we anticipate it will be approximately $10.0 million in 2009. These expenditures will be primarily focused on research and
development and cost savings initiatives and will be incurred mostly in the second half of 2009.

Cash flows from financing activities

Net cash provided by (used in) financing activities was ($2.6) million and $20,000 for the three months ended March 31, 2009 and 2008, respectively. Net cash used
in financing activities for the three months ended March 31, 2009 reflects stock repurchases of $2.6 million. Net cash provided from financing activities for the three months ended March 31, 2008 reflects $61,000 from proceeds from stock
option exercises partially offset by remaining costs of $10,000 from our IPO and $29,000 of payments made on a capital lease.

Future liquidity
requirements

We believe that our existing cash, cash equivalents, investments and anticipated cash flows from operating activities will be sufficient
to meet our anticipated cash needs for at least the next 12 months. Our cash needs include cash required to fund our operations, taking into account anticipated lower revenue and possible slower accounts receivable collections. If the assumptions
underlying our business plan regarding future revenues and expenses change, or if unexpected opportunities or needs arise, we may seek to raise additional cash by selling equity or convertible debt securities. If we raise additional funds through
the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing
stockholders. If we obtain debt financing, a substantial portion of our operating cash flow may be dedicated to the payment of principal and interest on such indebtedness, and the terms of the debt securities issued could impose significant
restrictions on our operations. If we are unable to obtain financing on terms favorable to us, we may be unable to successfully execute our business plan.

Contractual obligations

The contractual obligations presented in the table below represent our estimates of future payments under fixed
contractual obligations and commitments at March 31, 2009. Changes in our business needs, as well as actions by third parties and other factors, may cause these estimates to change. Because these estimates are complex and necessarily
subjective, our actual payments in future periods are likely to vary from those presented in the table. The following table sets forth information relating to our contractual obligations at March 31, 2009:

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

We consider to be critical those accounting policies that require our most subjective or complex judgments, which often result from a need to make estimates about the effect of matters that are inherently uncertain,
and that are among the most important of our accounting policies in the portrayal of our financial condition and results of operations. We believe the following to be our critical accounting policies, including the more significant estimates and
assumptions used in preparation of our financial statements.

Revenue recognition

We recognize revenue from sales of products when:



| |  | Persuasive evidence of an arrangement exists. We require evidence of a purchase order with the customer specifying the terms and specifications of the
product to be delivered, typically in the form of a signed quotation or purchase order from the customer.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Title has passed and the product has been delivered. Title passage and product delivery generally occurs when the product is delivered to a common
carrier.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The price is fixed or determinable. All terms are fixed in the signed quotation or purchase order received from the customer. The purchase orders do not
contain rights of cancellation, return, exchanges or refunds.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Collection of the resulting receivable is reasonably assured. Our standard arrangement with customers includes 30 day payment terms. Customers are
subject to a credit review process that evaluates each customers financial position and its ability to pay. We determine collectability by considering the length of time the customer has been in business and our history of collections with
that customer. If we determine that collection is not probable, no product is shipped and no revenue is recognized unless cash is received in advance.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Contract research revenue is recognized as services are performed. We execute agreements with our customers that clearly describe the scope of the project, the services we will provide, ownership of any tangible or
intangible assets generated as part of the project, and the amount of consideration we will receive.

There are no significant judgments or estimates
associated with our revenue recognition policies or processes. All of our revenue is denominated in US dollars.

Inventory valuation

We value our inventory at the lower of cost or market. Market is determined based on net realizable value. Cost is determined for raw materials on a first-in, first-out
basis and work in process and finished goods are based on actual costs. We establish inventory reserves when conditions exist that suggest inventory may be in excess of anticipated demand or is obsolete based on customer required specifications. We
evaluate the ability to realize the value of our inventory based on a combination of factors, including forecasted sales, estimated current and future market value and changes in customers product specifications. Recoveries of previously
written-down inventory are recognized only when the related inventory is sold and revenue has been recognized. Based on current demand and pricing of our products, we believe that it is unlikely that significant adjustments for inventory
obsolescence will occur. Our method of estimating excess and obsolete inventory has remained consistent for all periods presented. However, if our recognition of excess or obsolete inventory is, or if our estimates of our inventorys potential
utility become, less favorable than currently expected, additional inventory reserves may be required. In accordance with SFAS 151, Inventory costs an amendment of ARB No. 43 Chapter 4, we determine our normal operating capacity and
record as expense costs attributable to lower utilization of equipment and staff. For the three months ended March 31, 2009, we determined we were not operating at capacity and recorded as expense costs associated with lower utilization of
equipment and staff of $2.9 million.

Investments

We
invest available cash primarily in investment grade commercial paper, corporate notes and government securities. While our investment policy no longer includes auction-rate securities as an approved investment, we continue to hold auction rate
securities purchased prior to the policy change. We also hold put options associated with an agreement with UBS, AG. Investments classified as available-for-sale securities are carried at fair market value with unrealized gains and losses recorded
in accumulated other comprehensive income (loss). Investments in trading securities are reported at fair value, with both realized and unrealized gains and losses recorded in other income (expense), net in the Statement of Operations. Investments in
which we have the ability and intent, if necessary, to liquidate in order to support our current operations are classified as short-term. Our long-term investments consist primarily of auction-rate securities and put options.

We review our available for sale securities investments at the end of each quarter for other-than-temporary declines in fair value based on the specific identification
method. We consider various factors in determining whether an impairment is other-than-temporary, including the severity and duration of the impairment, changes in underlying credit ratings, forecasted recovery, our ability and intent to hold the
investment for a period of time sufficient to allow for any anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. When we conclude that an other-than-temporary impairment has resulted,
the difference between the fair value and carrying value is written off and recorded as a charge on the Statement of Operations.

##### Table of Contents

In October 2008, we entered into an agreement that provides us with the right, but not the obligation, to sell all our
auction-rate securities to UBS, AG for par value during the period of June 30, 2010 to July 2, 2012 (the ARS Put Options). The ARS Put Options provide us with the opportunity to recover the estimated unrealized loss on our ARS
investments. We recorded the fair value of the ARS Put Options upon receipt and included it in other long-term assets on our March 31, 2009 balance sheet. In accordance with SFAS No. 159, The Fair Value Option for Financial Assets
and Financial LiabilitiesIncluding an Amendment of SFAS No. 115 (SFAS No. 159), which was adopted by us on January 1, 2008, we elected fair value accounting for the ARS Put Options. Unrealized gains and losses
related to the ARS Put Options will be recognized in earnings. We value the auction-rate securities and ARS Put Options using a discounted cash flow model that weights various factors including interest rates and expected holding period. At
March 31, 2009, the fair value recorded on the balance sheet of auction-rate securities and ARS Put Options was $9.6 million and $1.1 million, respectively.

Allowance for doubtful accounts

We estimate the allowance for doubtful accounts based on an assessment of the collectability of specific
customer accounts. The determination of risk for collection is assessed on a customer-by-customer basis considering our historical experience and future orders with the customer, changes in payment patterns, and recent information we have about the
current status of our accounts receivable balances. If we determine that a specific customer is a risk for collection, we provide a specific allowance for credit losses to reduce the net recognized receivable to the amount we reasonably believe will
be collected. We believe that, based on the customers to whom we sell and the nature of our agreements with them, our estimates are reasonable. Our method of estimating collectability has remained consistent for all periods presented and with past
collections experience. We believe that it is unlikely that significant adjustments to allowances for doubtful accounts will be necessary.

Stock-based
compensation

Effective January 1, 2006 we adopted SFAS 123R which amends SFAS 123 Accounting for Stock-Based Compensation
(SFAS 123), and requires us to expense stock options based upon the fair market value on the date of grant. We adopted SFAS 123R using the prospective method. Under this transition method, the provisions of SFAS 123R are applied to new
awards and to awards modified, repurchased, or cancelled after January 1, 2006. We selected the Black-Scholes option pricing model to determine the fair value of stock options. The determination of the fair value of stock-based payment awards
on the date of grant using an option-pricing model will be affected by assumptions regarding a number of complex and subjective variables. These variables include our expected stock volatility over the term of the awards, actual and projected
employee stock option exercise behaviors, risk-free interest rates, forfeitures and expected dividends.

The expected term represents the weighted-average
period that our stock options are expected to be outstanding and is based upon the vesting term of our options, a review of a peer group of companies, and expected exercise behavior. Until November 2007, we were operating as a private company, and,
as a result, we were unable to use our actual price volatility data. Therefore, we estimate the volatility of our common stock based on volatility of similar entities over the expected term of our stock options. We base the risk-free interest rate
that we use in the option pricing model on US Treasury zero-coupon issues with remaining terms similar to the expected term on the options. We do not anticipate paying any cash dividends in the foreseeable future and, therefore, use an expected
dividend yield of zero in the option pricing model. We are required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The current forfeiture rate of
30.39% was based on our past history of forfeitures.

We had a choice of two attribution methods for allocating compensation costs under SFAS 123R, the
straight-line method, which allocates expense on a straight-line basis over the requisite service period of the last separately vesting portion of an award, or the graded vesting attribution method, which allocates expense on
a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in substance, multiple awards. We chose the former method and amortized the fair value of each option on a straight-line
basis over the service period.

Based on the variables affecting the valuation of our common stock and the method used for allocating compensation costs,
we recognized $226,000 in stock compensation expense during the three months ended March 31, 2009.

Valuation methodologies employed

All option grants made during the three months ended March 31, 2009 and 2008 were granted at an exercise price per share equal to the closing
market price of our common stock on the date of grant. Therefore, there is no intrinsic value because the exercise price per share of each option was equal to the fair value of the common stock on the date of grant.

There was no aggregate intrinsic value of all stock options outstanding at March 31, 2009, based on the fair market
value of the common stock at March 31, 2009.

RECENT ACCOUNTING PRONOUNCEMENTS

On January 1, 2009, we adopted FASB Staff Position FAS 157-2, Effective Date of FASB Statement No. 157, which had delayed the effective date of SFAS 157 for nonfinancial assets and nonfinancial
liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), to fiscal years beginning after November 15, 2008. The adoption of FSP FAS 157-2 did not have a
material impact on our financial position or results of operations.

In April 2009, the FASB issued FSP FAS 107-1 and APB 28-1, Interim Disclosures
about Fair Value of Financial Instruments. This FASB Staff Position (FSP) amends Statement of Financial Accounting Standards (SFAS) No. 107, Disclosures About Fair Value of Financial Instruments, to
require disclosures about fair value of financial instruments for interim reporting periods of publicly traded companies as well as in annual financial statements. This FSP also amends APB Opinion No. 28, Interim Financial
Reporting, to require those disclosures in summarized financial information at interim reporting periods. This FSP is effective for interim reporting periods ending after June 15, 2009, with early adoption permitted for periods ending
after March 15, 2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial adoption, this FSP requires comparative purposes at initial adoption. In periods
after initial adoption, this FSP requires comparative disclosures only for periods ending after initial adoption. We do not expect the changes associated with adoption of this FSP will have a material effect on the determination or reporting of our
financial results.

In April 2009, the FASB issued FSP FAS 115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary
Impairments. This FSP amends the other-than-temporary impairment guidance for debt securities to make the guidance more operational and to improve the presentation and disclosure of other-than-temporary impairments on debt and equity
securities in the financial statements. This FSP does not amend existing recognition and measurement guidance related to other-than-temporary impairments of equity securities. This FSP is effective for interim and annual reporting periods ending
after June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial adoption,
this FSP requires comparative disclosures only for periods ending after initial adoption. We do not expect the changes associated with adoption of this FSP will have a material effect on the determination or reporting of our financial results.

In April 2009, the FASB issued FSP FAS 157-4, Determining Fair Value When the Volume and level of Activity for the Asset or Liability Have
Significantly Decreased and Identifying Transactions That Are Not Orderly. This FSP provides additional guidance for estimating fair value in accordance with SFAS No. 157, Fair Value Measurements, when the volume and level of
activity for the asset or liability have significantly decreased. This FSP also includes guidance on identifying circumstances that indicate a transaction is not orderly. This FSP is effective for interim and annual reporting periods ending after
June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial adoption, this
FSP requires comparative disclosures only for periods ending after initial adoption. We do not expect the changes associated with the adoption of this FSP will have a material effect on the determination or reporting of our financial results.

Effective January 1, 2009, we implemented SFAS No. 157, Fair Value Measurements, for our nonfinancial assets and liabilities that
are remeasured at fair value on a non-recurring basis. See Note 4 for disclosures associated with adoption of this standard.

OFF-BALANCE SHEET
ARRANGEMENTS

As of March 31, 2009, there have been no material changes in the off-balance sheet arrangements disclosed in the Managements
Discussion and Analysis section of our Annual Report on Form 10-K for the year ended December 31, 2008.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
|------- | ---------------------------------------------------------

Market
risk is the risk of loss related to changes in market prices, including interest rates, of financial instruments that may adversely impact our financial position, results of operations or cash flows. Global credit and financial markets have been
experiencing extreme disruption in recent months, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and uncertainty about economic
stability. There can be no assurance that there will not be further deterioration in credit and financial markets and confidence in economic conditions. These economic uncertainties affect businesses such as ours in a number of ways, making it
difficult to accurately forecast and plan our future business activities. The current tightening of credit in financial markets may continue to lead consumers and businesses to postpone spending, which may cause our customers to continue to
aggressively manage their inventories and delay their future orders with us. In addition, financial difficulties experienced by our suppliers or distributors could result in product delays, increased accounts receivable defaults and inventory
challenges. We are unable to predict the likely duration and severity of the current disruptions in the credit and financial markets and adverse global economic conditions, and if the current uncertain economic conditions continue or further
deteriorate, our business and results of operations could be materially and adversely affected.

Foreign currency exchange risk. To
date, substantially all of our international sales have been transacted in US dollars. Accordingly, we have limited exposure to foreign currency exchange rates and do not enter into foreign currency hedging transactions.

##### Table of Contents

Interest rate risk. We do not have any long-term borrowings. Our investments consist of cash, cash
equivalents, commercial paper, corporate, state and local bonds, US treasury securities, and auction-rate securities. The primary objective of our investment activities is to preserve principal while maximizing income without significantly
increasing risk. We do not enter into investments for trading or speculative purposes. Our investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our
investments. Due to the short-term nature of our investment portfolio, we do not believe an immediate 10% fluctuation in interest rates would have a material effect on the fair market value of our portfolio, and therefore, we do not expect our
operating results or cash flows to be materially affected by a sudden change in market interest rates.

Inflation. Our operations have
not been, and we do not expect them to be, materially affected by inflation. However, historically, the prices we charge our customers are market driven, and therefore we may not be able to increase our prices to offset any increase in our material
or labor costs. Our inability or failure to do so could harm our business, financial condition and results of operations.



|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Managements evaluation of
disclosure controls and procedures

Based on evaluations at March 31, 2009, our chief executive officer and chief financial officer (together, our
certifying officers), with the participation of the management team, have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the
Exchange Act)) are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the
rules and forms of the SEC, and that material information relating to the Company is accumulated and communicated to management, including our certifying officers, as appropriate to allow timely decisions regarding required disclosures.

Changes in internal control over financial reporting

Our
management, including our certifying officers, believes that a controls system, no matter how well designed and operated, is based in part upon certain assumptions about the likelihood of future events, and therefore can only provide reasonable, not
absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

Our certifying officers have concluded that there were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act)
during the three months ended March 31, 2009, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II



|ITEM 1. | LEGAL PROCEEDINGS
|------- | -----------------

From time to time we may be named in claims
arising in the ordinary course of business. Currently, there are no legal proceedings or claims pending against us or involving us that, in the opinion of our management, could reasonably be expected to have a material adverse effect on our business
or financial condition.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

Our business is influenced by many factors that are
difficult to predict, involve uncertainties that may materially affect actual results and are often beyond our control. We have identified a number of these risk factors in our Annual Report on Form 10-K for the year ended December 31, 2008,
which factors should be taken into consideration when reviewing the information contained in this report. There have been no material changes with regard to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended
December 31, 2008.

Recent Sales of Unregistered Securities

None.

Use of Proceeds

On November 15, 2007, our Registration Statement on Form S-1 (333-145880) covering the initial
public offering of our shares of common stock was declared effective by the SEC. We registered 5,500,000 shares of common stock to be sold by us, 1,200,000 shares to be sold by selling stockholders and an additional 1,005,000 shares to be
sold by us to cover an overallotment option granted to the underwriters. UBS Securities LLC, Canaccord Adams Inc., CIBC World Markets Corp. and Janney Montgomery Scott LLC acted as underwriters in the offering, and UBS Securities served as sole
book-running manager. The closing of the offering was on November 21, 2007, at which time we sold 6,505,000 shares (including the underwriters overallotment) and the selling stockholders sold 1,200,000 shares. The shares sold by
us and the selling stockholders were sold at a price to the public of $14.00 per share.

##### Table of Contents

The net offering proceeds to us after deducting expenses totaled approximately $81.0 million. We did not receive any
portion of the proceeds from the sale of shares by the selling stockholders. As of March 31, 2009, we had used approximately $7.6 million of the net proceeds to repay borrowings outstanding under the revolving line of credit financing agreement
with Hercules Technology Growth Capital, Inc. and to pay related fees and expenses. We also have used $5.7 million to repurchase shares of our common stock, $2.0 million to purchase Series D-1 preferred shares of Peregrine Semiconductor Corp. (one
of our customers) and $19.2 million on capital expenditures. We intend to use the remaining $46.5 million of the net proceeds for working capital and other general corporate purposes, including capital expenditures and research and development.

The principal purposes of the offering were to obtain additional capital, establish a public market for our common stock and facilitate our future access
to public capital markets.

Issuer Purchases of Equity Securities

In November 2008, we announced a repurchase plan approved by our Board of Directors authorizing the purchase of up to $15.0 million of our outstanding common stock over a period of two years. The stock repurchase
program authorizes the Company to purchase shares of our common stock in the open market at times and prices considered appropriate by the Company depending upon prevailing market conditions and other corporate considerations.

The following table provides information about purchases made during the quarter ended March 31, 2009, of equity securities that are registered by us pursuant to
Section 12 of the Exchange Act:
