The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to the unaudited consolidated financial statements. The Company regularly evaluates estimates and assumptions related to revenue recognition, allowances for doubtful accounts, warranty reserves, inventory reserves, share-based compensation, derivative valuation, purchased intangible asset valuations and useful lives, and deferred income tax asset valuation allowances. These estimates and assumptions are based on current facts, historical experience and various other factors that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results the Company experiences may differ materially and adversely from its original estimates. To the extent there are material differences between the estimates and the actual results, the Company’s future results of operations will be affected.

Financial Instruments

ASC Topic 825, “Financial Instruments,” defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties. The Company’s financial instruments include cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and various debt instruments. These financial instruments are stated at their carrying values, which are estimates of their fair values because of their nearness to cash settlement, except for the debt instruments disclosed below, or the comparability of their terms to the terms the Company could obtain, for similar instruments, in the current market.

Restricted cash consists of various commitments of ~~$0.4~~$1.9 million recorded in other current ~~assets, as well as~~assets; including cash designated for debt payment obligations of $1.5 million. In addition, there is an interest-bearing ~~certificates~~certificate of deposit (“CDs”) collateralizing letters of credit of $1.5 million, which are included in other assets in the Unaudited Consolidated Balance Sheets as of ~~March 31,~~June 30, 2011.

~~Effective February 4, 2011, the Company exchanged the existing Senior Term Loan into~~The Company’s debt consists of two term loans (the Term Loans A and B), each in the principal amount of $9.34 million.

Pursuant to ASC 470, the Company recorded the new Term Loans A and B, (see discussion in Note 3 Debt in the accompanying Notes to Unaudited Financial Statements.), issued in extinguishment of the Senior Term Loan at fair value and recognized a $3.9 million loss for the difference between the aggregate fair values of the new instruments plus additional amounts and fees paid to the noteholders compared to the net carrying value of the Senior Term Loan. For the purposes of calculating this loss on extinguishment, the net carrying amount of the Senior Term Loan was $18.7 million, which included the remaining outstanding principal of $17.0 million, the Payment-in-Kind (“PIK”) balance of $1.7 million, and the balance of the unamortized costs of $0.6 million, as of February 4, 2011.

The Company estimates the fair values of the Term Loans A and B using a convertible bond valuation model within a lattice framework. These valuations are determined using Level 3 inputs. The valuation model combines expected cash outflows with market-based assumptions regarding risk-adjusted yields, stock price volatility, recent price quotes and trading information of the Company’s common stock into which the Term B loan is convertible.

As of ~~March 31,~~June 30, 2011, the fair value ~~and~~of the Term A Loan was $10.2 million. The carrying value of the Term A Loan was ~~$9.9~~$9.8 million, ~~including an unamortized~~net of a $0.5 million remaining premium, which is amortized as interest expense over the life of ~~$0.5 million.~~the loan. The Term A Loan maturity date is February 4, 2014.

As of June 30, 2011, the fair value of the Term B Loan was ~~$11.9~~$9.7 million. The carrying value of the Term B Loan was $7.0 million, net of a $2.3 million remaining discount, which was amortized as interest expense over the life of the loan. The Term B Loan maturity date is October 30, 2014.

The Company estimates the fair values of the 2014 Debentures (convertible subordinated debt) and embedded derivatives using a convertible bond valuation model within a lattice framework. These valuations are determined using Level 3 inputs. The valuation model combines expected cash outflows with market-based assumptions regarding risk-adjusted yields, stock price volatility, recent price quotes and trading information of the Company’s common stock into which the 2014 Debentures are convertible. As of March 31, 2011, the fair value of the 2014 Debentures is $44.5 million excluding the fair value of the compound embedded derivative of $20.9 million. The change in fair value from September 30, 2010 is reflected as a loss on embedded derivative in the Unaudited Consolidated Statement of Operations for the three and six months ended March 31, 2011. As of March 31, 2011, the outstanding 2014 Debentures were carried on the balance sheet at $39.9 million, net of a $6.6 million remaining discount, which is amortized as interest expense over the life of the debentures.

The change in the fair value of the ~~compound~~ embedded derivative is primarily related to the change in price of the underlying common stock. The change in value of the ~~compound~~ embedded derivative is a non-cash item. At the Company’s option, it can settle the embedded derivative in either cash or common shares. As the Company intends to, and has the ability to, satisfy the obligations with equity securities, in accordance with ASC Topic 470 Debt (“ASC 470”), the Company has classified the liability as a long-term liability on its Unaudited Consolidated Balance Sheet as of ~~March 31,~~June 30, 2011.

As of June 30, 2011, the fair value of the 2014 Debentures was $45.1 million excluding the fair value of the embedded derivative of $13.0 million. The change in fair value of the embedded derivative from September 30, 2010 was reflected as a gain on embedded derivative in the Unaudited Consolidated Statement of Operations for the three and nine months ended June 30, 2011. As of June 30, 2011, the outstanding 2014 Debentures were carried on the balance sheet at $40.3 million, net of a $6.2 million remaining discount, which was amortized as interest expense over the life of the debentures.

Recent Accounting Pronouncements

In October 2009, the FASB issued ASU No. 2009-13, Revenue Recognition (ASC Topic 605) — Multiple-Deliverable Revenue Arrangements, a consensus of the FASB Emerging Issues Task Force. This guidance modifies the fair value requirements of ASC subtopic 605-25, Revenue Recognition-Multiple Element Arrangements by allowing the use of the best estimate of selling price in addition to vendor-specific objective evidence and verifiable objective evidence (now referred to as third-party evidence) for determining the selling price of a deliverable. A vendor is now required to use its best estimate of the selling price when vendor-specific objective evidence or third-party evidence of the selling price cannot be determined. In addition, the residual method of allocating arrangement consideration is no longer permitted. ASU 2009-13 is effective for fiscal years beginning on or after June 15, 2010. The Company has adopted the provisions of ASU 2009-13 and the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In October 2009, the FASB issued ASU No. 2009-14, Software (ASC Topic 985) — Certain Revenue Arrangements That Include Software Elements, a consensus of the FASB Emerging Issues Task Force. This guidance modifies the scope of ASC subtopic 985-605, Software-Revenue Recognition to exclude from its requirements (a) non-software components of tangible products and (b) software components of tangible products that are sold, licensed, or leased with tangible products when the software components and non-software components of the tangible product function together to deliver the tangible product’s essential functionality. ASU 2009-14 is effective for fiscal years beginning on or after June 15, 2010. The Company has adopted the provisions of ASU 2009-14 and the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In accordance with ASC Topic 260 Earnings per Share (“ASC 260”), basic net income and loss per share is computed by dividing net income or loss by the weighted average number of common shares outstanding during the period.

For the three ~~and six~~ months ended ~~March 31,~~June 30, 2011 and 2010, the Company recorded net income from operations and accordingly included common stock equivalents from convertible debentures, convertible loans, convertible preferred stock, stock options, and restricted stock units in the diluted earnings per share calculation.

For the nine months ended June 30, 2011 and 2010, the Company recorded a net loss ~~and in~~from operations. In accordance with ASC 260, all outstanding potential common shares were excluded from the diluted loss per share computation. For periods in which the Company reports a net loss, diluted loss per share is calculated using only the weighted average number of shares outstanding during each of the periods, as the inclusion of any common stock equivalents would be anti-dilutive.

Under the two-class method of determining earnings for each class of stock, the Company considers the dividend rights and participation rights in undistributed earnings for each class. For the three and six months ended March 31, 2011 and 2010 , the dividend rights on the outstanding preferred shares are not material to the calculation, and therefore, not considered in determining earnings and losses per preferred share. The allocation of undistributed earnings to preferred shares is equal to the amount of earnings per common share that would be distributed on an as-converted basis.

Note 3. Debt

As of ~~March 31,~~June 30, 2011, the outstanding 2014 Debentures were carried on the balance sheet at ~~$39.9~~$40.3 million, net of a ~~$6.6~~$6.2 million remaining discount. Unamortized debt issuance costs, as of ~~March 31,~~June 30, 2011, were ~~$0.9~~$0.8 million. The 2014 Debentures mature in October 2014 and bear interest at a fixed rate of 8.0% per annum. Interest is payable semi-annually.

On January 18, 2011, the Company paid $8.0 million against the principal balance of the Senior Term Loan. Effective February 4, 2011, the Company exchanged the existing Senior Term Loan ~~into~~for two term loans (the Term Loans A and B), each in the principal amount of $9.34 million.

The Term A Loan bears interest at a fixed rate of 10.5% per annum beginning on February 4, 2011, payable quarterly in arrears, with a maturity date of February 4, 2014. Prepayment of the Term A Loan iswas permitted at 101% of the principal amount plus accrued interest until August 4, 2011, after which the prepayment option ~~expires.~~expired.

The Term B Loan bears interest at a fixed rate of 8.0% per annum beginning on February 4, 2011, payable quarterly in arrears, with a maturity date of October 30, 2014, unless earlier converted. Prepayment of the Term B Loan is not permitted prior to October 30, 2011. On or after October 30, 2011, prepayments on the Term B Loan are permitted at 100% of the principal amount plus accrued interest, but only if the closing sale price of the common stock has been at least 130% of the conversion price in effect for at least 20 trading days during any 30 consecutive trading day period ending on the day prior to the date of notice of prepayment.

The Term B Loan is convertible into shares of common stock at a conversion price of $4.95 per share (equivalent to an initial conversion rate of approximately 202 shares per $1,000 principal amount of the Term B Loan). The terms of conversion for the Term B Loan are substantially similar to the conversion terms for the Company’s 2014 Debentures except that there is no make-whole interest amount payable upon conversion. Full conversion of the $9.34 million in aggregate principal amount of the Term B Loan would result in the issuance of 1,887,234 shares of common stock, as of February 4, 2011.

The Company evaluated the Term A and B Loans issued in exchange for the Senior Term Loan pursuant to the guidance in ASC 470. The Company determined that it has not received any concessions from the noteholders in connection with the ~~Second Amendment to Loan Agreement~~exchange and accordingly, the transaction ~~will~~was not be accounted for as a troubled debt restructuring. However, due to the addition of a substantive conversion feature ofin the ~~new instrument issued,~~Term B Loan, as compared to the terms of Senior Term Loan, the Company accounted for the exchange of instruments, in settlement for the Senior Term Loan, as a debt extinguishment, pursuant to the guidance in ASC 470.

Pursuant to ASC 470, the Company recorded the ~~new~~ Term Loans A and B, issued in extinguishment of the Senior Term Loan at fair value and recognized a $3.9 million loss for the difference between the aggregate fair values of the new instruments plus additional amounts and fees paid to the noteholders compared to the net carrying value of the Senior Term Loan. For the purposes of calculating this loss on extinguishment, the net carrying amount of the Senior Term Loan was $18.7 million, which included the remaining outstanding principal of $17.0 million, the Payment-in-Kind (“PIK”) balance of $1.7 million, and the balance of the unamortized costs of $0.6 million, as of February 4, 2011.

Table of Contents

On February 4, 2011, the Company recorded the Term A Loan at fair value, which was $9.9 million, including a premium of $0.6 ~~million,~~million. The difference between the fair value and the face value (principal) of the Term A Loan represents a premium that will be amortized as a reduction of interest expense over the life of the loan. The premium calculated for the Term A Loan decreased the Company’s effective interest rate ~~of interest~~ from the stated fixed rate of 10.5% per annum. At ~~March 31,~~June 30, 2011, the effective interest rate on the Term A Loan was 8.5%. The carrying value will decrease over the life of the Term A Loan as the excess of the fair value over the face value of the note is amortized.

As of ~~March 31,~~June 30, 2011, the fair value of the Term A Loan was $10.2 million, and was carried on the balance sheet at ~~$9.9~~$9.8 million, including the unamortized premium of $0.5 million. For the three and ~~six~~nine months ended ~~March 31,~~June 30, 2011, ~~interest expense~~the premium amortization related to the Term A Loan ~~premium~~ was ~~$0.03 million.~~ $0.05 million and $0.1 million, respectively.

On February 4, 2011, the Term B Loan fair value was determined to be $11.9 million, which included a premium of $2.6 million representing the difference between the fair value of the loan, including all terms and features of the note, and the face value of the note of $9.3 million. Since the note included an equity conversion feature, the $2.6 million premium was credited to additional paid in capital in accordance with ASC 470-20-25. Additionally, as the equity conversion feature allows for the Company to potentially settle any conversion request in either shares of its common stock or cash, at the Company’s option, itthe equity conversion feature was allocated a value of ~~$2.5~~$2.49 million calculated as the difference between the $9.3 million face value of the note and the $6.9 million estimated fair value of the note, as determined based upon the note as an assumed standalone instrument including all terms and features except the equity conversion feature. The allocated equity conversion feature value of ~~$2.5~~$2.49 million was recorded as a debt discount and a credit to additional paid in capital in accordance with ASC 470-20-15. The debt discount will be amortized as additional interest expense over the life of the debt using the effective interest method. Accordingly, the Term B loan debt discount increased the Company’s effective rate of interest from the stated or nominal fixed rate of 8.0% per annum to an effective interest rate of 17.7% per annum as of ~~March 31,~~June 30, 2011.

As of ~~March 31,~~June 30, 2011, the fair value of the Term B Loan was $9.7 million, and was carried on the balance sheet at ~~$6.9~~$7.0 million, net of the unamortized discount of ~~$2.4~~$2.3 million. For the three and ~~six~~nine months ended ~~March 31,~~June 30, 2011, ~~net interest expense~~the discount amortization related to the Term B Loan ~~discount~~ was $0.1 ~~million.~~million and $0.2 million, respectively.

11During the quarter ended June 30, 2011, the Company completed two transactions, from which $1.5 million in proceeds was restricted for the use in the partial payment of the Term A Loan. The 2nd amendment to the Term Loans A and B and the 2014 Debenture agreement each include requirements that the Company remit any cash proceeds generated from the sale of assets to pay principal on the outstanding debt, in a prescribed order of payment. The Company obtained a waiver from the noteholder allowing the Company to remit $1.5 million of the proceeds and to retain the remainder which is included in cash as of June 30, 2011. As such, the $1.5 million was classified as restricted cash and $1.5 million of the Term A loan was classified out of long-term liabilities and into current liabilities. On July 15, 2011, the Company used the $1.5 million set aside in restricted cash to pay a portion of the Term A Loan.

The ~~compound~~ embedded derivative liability, which is included in long term liabilities, represents the value of the equity conversion feature and a “make-whole” feature of the 2014 Debentures. The make-whole feature, requiring the Company to redeem foregone interest upon conversion by the holder, which for accounting purposes results in the exercise price not being indexed to the Company’s own stock, which in turn results in the presentation of the ~~compound~~ embedded derivative as a standalone liability at fair value.

There is no current observable market for this type of derivative and, as such, the Company determined the value of the embedded derivative using a lattice-based convertible bond valuation model that combined expected cash outflows with market-based assumptions. The fair value of the 2014 Debentures (convertible subordinated debt) without the embedded ~~compound~~ derivative feature was also estimated using a convertible bond valuation model within a lattice framework. The convertible bond valuation model combined expected cash outflows with market-based assumptions regarding risk-adjusted yields, stock price volatility and recent price quotes and trading information regarding shares of the Company’s common stock into which the 2014 Debentures are convertible. ~~The Company will mark the embedded derivative to market due to~~As the conversion price is not being indexed to the Company’s own ~~stock.~~stock, the embedded derivative is bifurcated and presented on the balance sheet at fair value and the embedded derivative will be marked to market. The change in the fair value of the bifurcated ~~compound~~ embedded derivative is primarily related to the change in price of the underlying common stock.

The valuation methodologies used by the Company as described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although management believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Note 5. Income Taxes

The provision for income taxes as a percentage of income from operations before income taxes was ~~(0.75%)~~0.72% for the ~~six~~nine months ended ~~March 31,~~June 30, 2011 compared to ~~(9.73%)~~8.84% for the comparable period in the prior year. For the year ending September 30, 2011, the Company’s estimated effective tax rate is ~~(1.51%~~(1.43%). The Company’s effective tax rate is primarily impacted by operating losses.

Because the Company has historically experienced net tax losses, the Company has placed a valuation allowance against its otherwise recognizable deferred tax assets.

Overview

Over the last 10 years, the worldwide proliferation of the Internet and the rapid growth in the volume of data being sent over LANs and WANs has placed a tremendous strain on the existing communications infrastructure. Communication service providers have sought to increase their revenues by delivering a growing range of data services to their customers in a cost-effective manner. The resulting demand for increased bandwidth and services has created a need for faster, larger and more complex networks.

The Company is a leading supplier of high-performance integrated circuits (“ICs”) principally targeted at systems manufacturers in the communications industry. Within the communications industry, the Company’s products address Carrier and Enterprise Networking, where they enable data to be transmitted at high-speeds and processed and switched under a variety of protocols.

In recent years, the Company has focused its product development and marketing efforts on products that leverage the convergence of Carrier and Enterprise Networking onto Internet Protocol based networks. These “Next-Generation Networks” share the requirements of high reliability, scalability, interoperability and low cost. Increasingly, these networks will be delivered based on Ethernet technology. The Company believes that products in this emerging technology area represent the best opportunity for the Company to provide differentiation in the market.

~~Debt Restructuring~~

~~The Company exchanged the Senior Term Loan Agreement effective February 4, 2011, to convert the existing Senior Term Loan into two term loans, each in the principal amount of $9.34 million.~~

The Term A Loan bears interest at a fixed rate of 10.5% per annum beginning on February 4, 2011, payable quarterly in arrears, with a maturity date of February 4, 2014. Prepayment of the Term A Loan is permitted at 101% of the principal amount plus accrued interest until August 4, 2011 after which the prepayment option expires.

~~Table of Contents~~

interest amount payable upon conversion. Full conversion of the $9.34 million in aggregate principal amount of the Term B Loan would result in the issuance of 1,887,234 shares of common stock as of February 4, 2011.

On February 4, 2011, the Term B Loan fair value was determined to be $11.9 million, which included a premium of $2.6 million representing the difference between the fair value of the loan, including all terms and features of the note, and the face value of the note of $9.3 million. Since the note included an equity conversion feature, the $2.6 million premium was credited to additional paid in capital in accordance with ASC 470-20-25. Additionally, as the equity conversion feature allows for the Company to potentially settle any conversion request in either shares of its common stock or cash, at the Company’s option, it was allocated a value of $2.5 million calculated as the difference between the $9.3 million face value of the note and the $6.9 million estimated fair value of the note, as determined based upon the note as an assumed standalone instrument including all terms and features except the equity conversion feature. The allocated equity conversion feature value of $2.5 million was recorded as a debt discount and a credit to additional paid in capital in accordance with ASC 470-20-15. The debt discount will be amortized as additional interest expense over the life of the debt using the effective interest method. Accordingly, the Term B loan debt discount increased the Company’s effective rate of interest from the stated or nominal fixed rate of 8.0% per annum to an effective interest rate of 17.7% per annum as of March 31, 2011. As of March 31, 2011, the Term B Loan was carried on the balance sheet at $6.9 million, net of the unamortized discount of $2.4 million. For the three and six months ended March 31, 2011, net interest expense related to the Term B Loan discount was $0.1 million.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are described in our Annual Report on Form 10-K for the year ended September 30, 2010. There have been no significant changes to these policies during the ~~six~~nine months ended ~~March 31,~~June 30, 2011. These policies and estimates continue to be those that we believe are most important to a reader’s ability to understand our financial results.

These uses were partially offset by the generation of ~~amortization~~cash from the collection of ~~debt discounts.~~accounts receivable.

~~Accounts receivable decreased by $0.4 million to $15.4 million at March 31, 2011 from $15.8 million at September 30, 2010.~~ The decrease in accounts receivable is primarily due to the timing of sales and a decrease in revenues compared to the same period last year. ~~Inventory decreased by $1.4 million to $25.9 million at March 31, 2011 from $27.3 million at September 30, 2010.~~ The ~~Company decreased purchasing in the first and second quarters of fiscal year 2011 as compared to the same periods in 2010.~~

~~Accounts payable decreased by $2.1 million to $11.1 million at March 31, 2011 from $13.2 million at September 30, 2010. Accounts payable decreased primarily~~lower inventory is due to areduced purchases and production resulting from lower sales and an effort to reduce inventory levels. Lower accounts payable is due to the reduction in purchases from our suppliers once industry-wide material shortages eased, as well as the timing of payments to our vendors and other service providers. Accrued expenses and other liabilities decreased ~~by $3.3 million to $13.0 million at March 31, 2011 from $16.3 million at September 30, 2010. Accrued expenses and other liabilities decreased~~ primarily due to the payment of the $3.0 million SEC settlement, which was accrued for in prior years.

During the nine months ended June 30, 2010, cash provided by operations totaled $1.0 million. We used $0.8 million to fund the cash portion of our net loss which excludes non-cash items including depreciation and amortization, loss on extinguishment of debt and share based compensation. We also used $5.4 million of cash to build up our inventory levels. These uses were partially offset by the generation of cash from the collection of accounts receivable and increase in current liabilities. For the nine months ended June 30, 2010, cash generated by operating activities totaled $6.4 million. The decrease in accounts receivable is primarily due to the timing of sales and a decrease in revenues compared to the same period last year. The higher inventory was due to increased purchases and production resulting from higher anticipated demand. Higher accounts payable is due to the increased in purchases from our suppliers as well as the timing of payments to our vendors and other service providers.

Liquidity and Capital Resources, Contingent Liabilities and Operating Leases

~~Prospective~~Liquidity and Capital ~~Needs~~Resources

Our principal sources of liquidity are our existing cash and cash equivalent balances, cash generated from product sales, and the sales or licensing of our intellectual property, including the sale of patents. As of June 30, 2011, our cash and cash equivalents totaled $18.2 million. Our working capital at June 30, 2011 was $33.0 million. As of September 30, 2010, our cash and cash equivalents totaled $38.1 million and working capital was $48.0 million.

In order to achieve sustained profitability and positive cash flows from operations, we may need to further reduce operating expenses and/or increase revenue. We have completed a series of cost reduction actions, which have improved our operating expense structure and we will continue to perform additional actions, as necessary. Our ability to maintain, or increase, current revenue levels to sustain profitability will depend, in part, on demand for our products. The Company believes that its existing ~~sources of liquidity,~~cash and cash equivalent balances, along with cash expected to be generated from product sales and the sale ~~and~~or licensing of ~~IP,~~our intellectual property, including the sale of patents, will be sufficient to fund its operations and research and development efforts, anticipated capital expenditures, working capital, and other financing requirements for the next 12 months.

On July 15, 2011, we prepaid $1.5 million of our Term A loan, and we have no other principal payments on currently outstanding debt due in the next 12 months.

In order to increase our working capital, we may seek to obtain additional debt or equity financing. However, we cannot assure you that such financing will be available to us on favorable terms, or at all, particularly in light of recent economic conditions in the capital markets.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our quantitative and qualitative disclosures about market risk are described in our Annual Report on Form 10-K for the year ended September 30, 2010. There have been no material changes to these risks during the ~~six~~nine months ended ~~March 31,~~June 30, 2011.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the Company’s management, including its Chief Executive Officer and Chief Financial Officer, the Company has evaluated the effectiveness of the design and operation of its disclosure controls and procedures, as(as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange ~~Act.~~Act) as of June 30, 2011. Disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in the reports the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within required time periods, and is accumulated and communicated to the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of ~~March 31,~~June 30, 2011, these disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the three months ended ~~March 31,~~June 30, 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitation on the Effectiveness of Internal Controls

The effectiveness of any system of internal control over financial reporting is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting can only provide reasonable, not absolute, assurances. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. The Company intends to continue to monitor and upgrade its internal controls as necessary or appropriate for the business, but cannot assure you that such improvements will be sufficient to provide effective internal control over financial reporting.
