Notes to the Unaudited Consolidated Financial Statements

For the three and nine months ended March 31, 2011 and 2010

1.	Basis of Presentation

The accompanying consolidated financial statements are those of IsoRay, Inc., and its wholly-owned subsidiaries (IsoRay or the Company). All significant intercompany accounts and transactions have been eliminated in consolidation.

The accompanying interim consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, consistent in all material respects with those applied in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2010. The financial information is unaudited but reflects all adjustments, consisting only of normal recurring accruals, which are, in the opinion of the Company’s management, necessary for a fair statement of the results for the interim periods presented. Interim results are not necessarily indicative of results for a full year. The information included in this Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2010.

Certain amounts in the prior-year financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on net loss or shareholders’ equity as previously presented.

2. New Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the “FASB”) or other standards setting bodies that are adopted by us as of the specified effective dates. Unless otherwise discussed, we believe the impact of recently issued standards that are not yet effective will not have a material impact on our consolidated financial position, results of operations and cash flows upon adoption.

3. Loss per Share

Basic earnings per share is calculated by dividing net income (loss) available to common shareholders by the weighted average number of common shares outstanding, and does not include the impact of any potentially dilutive common stock equivalents. Common stock equivalents, including warrants and options to purchase the Company's common stock, are excluded from the calculations when their effect is anti-dilutive. At March 31, 2011 and 2010, the calculation of diluted weighted average shares did not include preferred stock, common stock warrants, or options that are potentially convertible into common stock as those would be anti-dilutive due to the Company’s net loss position.

Securities not considered in the calculation of diluted weighted average shares, but that could be dilutive in the future as of March 31, 2011 and 2010, were as follows:

	March 31,
	2011		2010
Preferred stock		59,065		59,065
Common stock warrants		3,819,185		3,216,644
Common stock options		2,146,372		2,317,237

Total potential dilutive securities		6,024,622		5,592,946

4. Inventory

Inventory consisted of the following at March 31, 2011 and June 30, 2010:

	March 31,		June 30,
	2011		2010
Raw materials	$	625,493	$	546,080
Work in process		83,053		130,840
Finished goods		20,259		4,757

	$	728,805	$	681,677

5. Share-Based Compensation

The following table presents the share-based compensation expense recognized during the three and nine months ended March 31, 2011 and 2010:

	Three months				Nine months
	ended March 31,				ended March 31,
	2011		2010		2011		2010
Cost of product sales	$	8,470	$	5,506	$	25,410	$	16,778
Research and development expenses		5,409		1,840		16,229		2,176
Sales and marketing expenses		96		19,599		7,790		70,684
General and administrative expenses		6,398		7,863		19,193		25,647
Total share-based compensation	$	20,373	$	34,808	$	68,622	$	115,285

As of March 31, 2011, total unrecognized compensation expense related to stock-based options was $164,208 and the related weighted-average period over which it is expected to be recognized is approximately 1.03 years.

The Company currently provides stock-based compensation under three equity incentive plans approved by the Board of Directors. Options granted under each of the plans have a ten year maximum term, an exercise price equal to at least the fair market value of the Company’s common stock on the date of the grant, and varying vesting periods as determined by the Board. For stock options with graded vesting terms, the Company recognizes compensation cost on a straight-line basis over the requisite service period for the entire award.

A summary of stock options within the Company’s share-based compensation plans as of March 31, 2011 was as follows:

	Number of Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value
Outstanding at March 31, 2011		2,146,372	$	1.87		6.5	$	763,796
Vested and expected to vest at
March 31, 2011		2,059,546	$	1.93		6.4	$	696,406
Vested and exercisable at
March 31, 2011		1,614,293	$	2.27		6.0	$	423,151

There were no options exercised during the nine months ended March 31, 2011 and there were 40,000 options exercised during the nine months ended March 31, 2010, respectively. The Company’s current policy is to issue new shares to satisfy option exercises.

The weighted average fair value of stock option awards granted and the key assumptions used in the Black-Scholes fair value model to calculate the fair value are as follows:

	Three months ended March 31,						Nine months ended March 31,
	2011(a)			2010(b)			2011(c)			2010(d)
Weighted average fair value of options granted	$	-		$	0.56		$	-		$	0.68
Key assumptions used in determining fair value:
Weighted average risk-free interest rate		-	%		1.93	%		-	%		2.55	%
Weighted average life of the option (in years)		-			3.75			-			4.75
Weighted average historical stock price volatility		-	%		101.84	%		-	%		134.89	%
Expected dividend yield		-	%		0.00	%		-	%		0.00	%

(a)	During the three months ended March 31, 2011, the Company did not grant any stock options.

(b)	During the three months ended March 31, 2010, the Company granted 30,000 stock options.

(c)	During the nine months ended March 31, 2011, the Company did not grant any stock options.

(d)	During the nine months ended March 31, 2010, the Company granted 40,000 stock options.

The Black-Scholes fair value model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Although the Company is using the Black-Scholes fair value model, management believes that because changes in the subjective input assumptions can materially affect the fair value estimate, this valuation model does not necessarily provide a reliable single measure of the fair value of its stock options. The risk-free interest rate is based on the U.S. treasury security rate in effect as of the date of grant. The expected option lives, volatility, and forfeiture assumptions are based on historical data of the Company.

6. Commitments and Contingencies

Patent and Know-How Royalty License Agreement

The Company is the holder of an exclusive license to use certain “know-how” developed by one of the founders of a predecessor to the Company and licensed to the Company by the Lawrence Family Trust, a Company shareholder. The terms of this license agreement require the payment of a royalty based on the Net Factory Sales Price, as defined in the agreement, of licensed product sales. Because the licensor’s patent application was ultimately abandoned, only a 1% “know-how” royalty based on Net Factory Sales Price, as defined in the agreement, remains applicable. To date, management believes that there have been no product sales incorporating the “know-how” and therefore no royalty is due pursuant to the terms of the agreement. Management believes that ultimately no royalties should be paid under this agreement as there is no intent to use this “know-how” in the future.

The licensor of the “know-how” has disputed management’s contention that it is not using this “know-how”. On September 25, 2007 and again on October 31, 2007, the Company participated in nonbinding mediation regarding this matter; however, no settlement was reached with the Lawrence Family Trust. After additional settlement discussions, which ended in April 2008, the parties failed to reach a settlement. The parties may demand binding arbitration at any time.

Wrongful Death Claim resulting from an automobile accident

The Company and a former employee have been named as defendants in a wrongful death claim in the State of Indiana as the result of an automobile accident. The suit alleges that the individual died as the result of a medical condition alleged to be the result of injuries sustained in the automobile accident. The claim if upheld at trial is not expected to result in an award of damages that will exceed the available insurance coverage. However, if the court awards exemplary damages then this award may have a financial impact on the Company. Management plans to vigorously defend the claim.

7. Fair Value Measurements

Effective July 1, 2008, for the financial assets and liabilities of the Company, and effective July 1, 2009, for the non-financial assets and liabilities of the Company, disclosure requirements were expanded to include the following information for each major category of assets and liabilities that are measured at fair value on a recurring basis: financial assets of the Company include cash and cash equivalents, and restricted cash - these are measured using level 1 inputs. Financial liabilities of the Company include the warrant liability measured using level 2 inputs, calculated using the Black-Scholes fair value model with stock price, exercise price, term, volatility and a discount rate based on the appropriate Treasury rate.

8. Preferred Dividends

On December 8, 2010, the Board of Directors declared a dividend on the Series B Preferred Stock of all currently payable and accrued outstanding and cumulative dividends through December 31, 2010 in the amount of $10,632.

As of March 31, 2010, there were dividends on Series B Preferred Stock outstanding in the amount of $2,658.

9. Shareholders’ Equity

On November 22, 2010, the Company entered into a Securities Purchase Agreement (as amended on December 27, 2010 and March 31, 2011) as part of the Company’s registered offering with an institutional investor and closed the transaction on November 24, 2010 for the sale of 2,250,000 shares of common stock and four series of warrants. The total warrants exercisable in Series A, Series B and Series C will be a maximum aggregate of 2,168,026 for a maximum number of below market securities issued, together with the shares of common stock sold in the offering, of no greater than 4,418,026 shares of common stock, which is the maximum issuable under the NYSE AMEX requirements without obtaining shareholder approval for the issuance. Series D Warrants which are not below market securities are expected to be issued to purchase 1,873,641 shares of common stock.

The exercise price of each of the Series A, B and C Warrants will be equal to the lower of (i) $1.50 and (ii) 90% of the average of the 3 lowest volume weighted average prices out of the 15 trading days preceding the exercise date, but in no event will the exercise price of the Series A Warrants be less than $0.75 per share. The Warrants have terms varying from one hundred twenty days from the Offering closing date for the Series A Warrants to six months from the Offering closing date for the Series B Warrants to five years from the initial exercisability date for the Series C and D Warrants. The Series A, B and C Warrants were immediately exercisable following the closing of the Offering. The Series D Warrants will not be exercisable until six months after the Closing and will have an exercise price equal to $1.56.

By letter agreement dated October 27, 2010, LifeTech Capital, a division of Aurora Capital, LLC, acted as placement agent in connection with the placement of the securities in this offering. LifeTech received a cash fee of 5% of the gross proceeds received under the Offering (excluding proceeds received on the exercise of C or D Warrants), and will also receive warrants to purchase 3% of the common stock sold in the Offering and 3% of the Series A, B and C Warrants exercised at any time, which warrants issued to LifeTech shall not be exercisable for six months following the closing, shall have a five year term, and an exercise price of $1.56 per share.

The warrant holder exercised the Series A Warrants on March 24, 2011 and received 538,660 shares of common stock at exercise in exchange for $475,000, net of commission expense.

All of the Series B warrants will be eligible to be exercised at the option of the Company at any time on or before 6 months after their issuance provided the common stock is trading at or above $2.45 for 20 cumulative trading days and to meeting other equity conditions and 562,500 of the Series C warrants will be eligible to be exercised at the option of the Company at any time on or before 6 months after their issuance provided the common stock is trading at or above $2.55 for 20 cumulative trading days and to meeting other equity conditions .

Based on the guidance contained in ASC 815, management had concluded that the warrants in Series A-1, Series B-1, and Series C-1 should be classified a liability and had recorded a liability at fair value. The Company determined the fair value of the warrants using the Black-Scholes fair value model. The Company determined the fair value of the warrants to be $1,724,000 on the date of the offering. The Company has recognized a gain on the change in fair value of $257,000 in the nine months ended March 31, 2011.

During the three months ended March 31, 2011, the Company and the warrant holder agreed to a modification of the Series C-1 warrants that allowed the Company to reclassify these warrants as equity. The Company reclassified the fair value as of March 31, 2011 of the Series C-1 warrant liability in the amount of $1,119,000 to additional paid in capital during the three months ended March 31, 2011. The Company expensed the unamortized portion of the deferred financing costs related Series C-1, these expenses were in the amount of $142,809.

On March 24, 2011, the warrant holder exercised the Series A-1 warrants. The Company reclassified the fair value as of the exercise date of the Series A-1 warrant liability in the amount of $119,000 to additional paid in capital during the three months ended March 31, 2011. The Company expensed the unamortized portion of the deferred financing costs related Series A-1warrants, these expenses were in the amount of $16,044.

ITEM 2 – MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Caution Regarding Forward-Looking Information

In addition to historical information, this Form 10-Q contains certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 (“PSLRA”). This statement is included for the express purpose of availing IsoRay, Inc. of the protections of the safe harbor provisions of the PSLRA.

All statements contained in this Form 10-Q, other than statements of historical facts, that address future activities, events or developments are forward-looking statements, including, but not limited to, statements containing the words "believe," "expect," "anticipate," "intends," "estimate," "forecast," "project," and similar expressions. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including any statements of the plans, strategies and objectives of management for future operations; any statements concerning proposed new products, services, developments or industry rankings; any statements regarding future economic conditions or performance; any statements of belief; and any statements of assumptions underlying any of the foregoing. These statements are based on certain assumptions and analyses made by us in light of our experience and our assessment of historical trends, current conditions and expected future developments as well as other factors we believe are appropriate under the circumstances. However, whether actual results will conform to the expectations and predictions of management is subject to a number of risks and uncertainties described under “Risk Factors” beginning on page 25 below and in the “Risk Factors” section of our Form 10-K for the fiscal year ended June 30, 2010 that may cause actual results to differ materially.

Consequently, all of the forward-looking statements made in this Form 10-Q are qualified by these cautionary statements and there can be no assurance that the actual results anticipated by management will be realized or, even if substantially realized, that they will have the expected consequences to or effects on our business operations. Readers are cautioned not to place undue reliance on such forward-looking statements as they speak only of the Company's views as of the date the statement was made. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Critical Accounting Policies and Estimates

The discussion and analysis of the Company’s financial condition and results of operations are based upon its consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an on-going basis, management evaluates past judgments and estimates, including those related to bad debts, inventories, accrued liabilities, and contingencies. Management bases its estimates on historical experience and on various other assumptions that are believed 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. Actual results may differ from these estimates under different assumptions or conditions. The accounting policies and related risks described in the Company’s annual report on Form 10-K as filed with the Securities and Exchange Commission on September 28, 2010 are those that depend most heavily on these judgments and estimates. As of March 31, 2011, there had been no material changes to any of the critical accounting policies contained therein. Management continues to estimate that the effective tax rate for the Company is at 0%.

Results of Operations

Three months ended March 31, 2011 compared to three months ended March 31, 2010

Revenues. Total revenues for the three months ended March 31, 2011 increased 17% as compared to the three months ended March 31, 2010. The overall increase of 17% was a combination of an 8% increase in revenue from prostate brachytherapy and a 371% increase in other treatments which include the treatment of lung and brain modalities.

The prostate revenue increase was the first quarter over quarter increase that the Company has experienced during the current fiscal year when compared to fiscal year 2010. The increase in revenue during the three months ended March 31, 2011 is attributed to an increase in acceptance by physicians of the Cesium-131 Brachytherapy seeds as one of the more clinically effective and cost effective treatment methods in the marketplace for treating prostate cancer.

The other treatments which include lung and brain treatments experienced significant growth of 371% in the three months ended March 31, 2011 compared to the three months ended March 31, 2010. The other revenue growth is attributed to the increased acceptance of Cesium-131 as a clinically effective treatment method for these additional body sites. The increased acceptance of the Cesium-131 Brachytherapy seeds is the result of physicians having positive experiences in using Cesium-131 in the treatment of over 100 patients for these new modalities at a number of major cancer centers across the United States. The other treatment revenue represents approximately 11% of revenues during the three months ended March 31, 2011 when compared to approximately 3% of revenues in the three months ended March 31, 2010. The Company anticipates that revenues will continue to grow in prostate revenue and will continue to accelerate in other revenue as existing treatments for non-prostate modalities continue their growth and as the new products under development are accepted into the market.

Total product sales	$	1,410,694	$	1,203,216	$	207,478		17	%

Cost of product sales. Cost of product sales continued to be reduced in a quarter over quarter comparison. Costs for the three months ended March 31, 2011 were reduced by $ 97,462 compared to the three months ended March 31, 2010. This cost reduction was attributable to two key operating factors. First, the Company continued to reduce labor costs attributed to the production of the Cesium-131 seeds and second, physicians continued to shift their ordering directions for the pre-loading of the seeds to our in-house pre-loading service in lieu of using a third party contracted loading service.

The cost savings in payroll and benefits were the result of the Company investing in Research and Development through the use of production staff to conduct projects. In addition, the Company was able to produce enough seeds to create the 17% increase in revenue while using approximately the same cost of materials as in the three months ended March 31, 2010. This increase in revenue while using the same amount of materials cost was accomplished through the increased pre-loading of seeds. By increasing the pre-loading of seeds at the Company, the Company was able to utilize the same amount of isotope that would have been lost to decay during transit time while shipping seeds to third-party loaders. The Company also gained increased control over the manufacturing process by completing more production activities within their facilities.

Gross profit. Gross profit increased $ 304,940 comparing the three months ended March 31, 2011 to the three months ended March 31, 2010. Gross profit for the three months ended March 31, 2011 increased to $ 357,426 from $ 52,486 in the three months ended March 31, 2010. The increase of 581% is attributed to an increase of sales of $207,478 and a decrease in cost of product sales of $97,462.

The gross profit percentage improved from approximately 4% for the three months ended March 31, 2010 to approximately 25% for the three months ended March 31, 2011. The improved percentage is directly a result of increasing sales combined with the reducing costs of product sales.

Research and development. Research and development costs have increased in the three months ended March 31, 2011 compared to the three months ended March 31, 2010 by $ 145,220 or 147%. The research and development increases are primarily attributed to increased efforts on research related to other organ treatments particularly the brain, lung and breast sites. The increased research and development costs include additional cost related to material and labor utilized in these research activities. The Company expects to continue to increase research and development costs to further develop new treatments and may initiate new protocols associated with these treatments.

These research and development costs represent 17.3% of revenues during the three months ended March 31, 2011 as compared to 8.1% of revenue during the three months ended March 31, 2010. The Company expects to continue to focus on the development of treatments for new modalities in the body and expects to continue to invest in research and development efforts going forward.

Research and development costs were partially offset by reimbursements recorded in the amount of $56,118 recorded in the consolidated statements of operations on the line described as research and development reimbursement.

Research and development costs for the three months ended March 31, 2011 increased compared to the three months ended March 31, 2010 as a direct result of the receipt of three IRS Qualifying Therapeutic Device Program grants. The grant awards total approximately $526,510. In the three months ended March 31, 2011, the Company recorded and received as other research and development reimbursement half of the qualifying expenses incurred in fiscal year 2010 and awarded in October 2010. The Company has evaluated the expense associated with each grant effort on a monthly basis and recorded half of the expense incurred until the individual grant limits are reached as research and development reimbursement and in other receivables as part of prepaid expenses and other current assets. The Internal Revenue Service will reimburse the Company in July 2011 for the amounts incurred in fiscal year 2011 based on the grant notice.

Sales and marketing expenses. Sales and marketing expenses were reduced by 47% in the three months ended March 31, 2011 as compared to the three months ended March 31, 2010. The costs were reduced from $ 447,693 in the three months ended March 31, 2010 to $ 235,553 in the three months ended March 31, 2011. The significant reduction of $212,487 is a result of reductions in consulting; marketing and advertising; payroll, benefits and share-based compensation; and travel expenses.

Despite a 47% reduction in sales and marketing expenses, overall sales increased 17% during the three months ended March 31, 2011 compared to the three months ended March 31, 2010. Management attributes the increase in sales to the increased acceptance of the product particularly in the treatment of new body sites. Overall, the reduction in sales and marketing expense did not adversely affect the revenue of the Company. Management believes that it has right sized the sales staff to the current market conditions and will consider expanding the staff when the current staff does not have the capacity to service their existing customer base while making new sales calls on qualified new customers.

General and administrative expenses increased $ 31,369 to $627,593 in the three months ended March 31, 2011 from $596,224 in the three months ended March 31, 2010. The general and administrative expenses have remained stable in this area as there have been no significant changes in the administrative function of the Company during the comparable periods.

Revenues. Overall revenues for the nine months ended March 31, 2011 remain materially unchanged compared to the nine months ended March 31, 2010.

The other revenue including brain and lung modalities had significant growth in revenue of 371% for the three months ended March 31, 2011 that continued the growth already experienced in the first two quarters of the fiscal year. For the nine months ended March 31, 2011, the other revenue segment experienced overall growth of 221% or $241,297. The other revenue growth is attributed to the increased acceptance of Cesium-131 as a clinically effective treatment method for these additional body sites. The increased acceptance of the Cesium-131 Brachytherapy seeds is the result of physicians having positive experiences in using Cesium-131 in the treatment of over 100 patients for these new modalities at a number of major cancer centers across the United States. Other treatments now represent approximately 12% of revenues versus approximately 3% of revenues in 2010.

The prostate segment of the business experienced an 8% growth in revenue for the three months ended March 31, 2011 to bring the nine months ended March 31, 2011 to 95% of the prostate segment revenues at $3,632,031 for the nine months ended March 31, 2010.

The research and development expense increased primarily as the result increased efforts on the research of other organs treatments particularly in relation to brain, lung and breast cancers. These increased costs include additional material and labor cost associated to these research activities. The Company expects to continue to invest in further development of the new treatments and may initiate new protocols associated with these treatments.

These costs represent 9% of revenue in the nine months ended March 31, 2011 as compared to 6% of revenue in the nine months ended March 31, 2010. The Company intends to continue to invest in the development of treatments related to new modalities in the body and expects to continue to have increased research and development expense going forward.

Research and development costs for the nine months ended March 31, 2011 increased compared to the nine months ended March 31, 2010 as a direct result of the receipt of three IRS Qualifying Therapeutic Device Program grants. The grant awards total approximately $526,510. In the nine months ended March 31, 2011, the Company recorded and received as other research and development reimbursement for half of the qualifying expenses incurred in fiscal year 2010 and awarded in October 2010.

Sales and marketing expenses. Sales and marketing expenses were reduced by 37% in the nine months ended March 31, 2011 as compared to the nine months ended March 31, 2010. These costs were reduced from $1,494,572 in the nine months ended March 31, 2010 to $944,244 in the nine months ended March 31, 2011. The significant reduction of $550,328 is a result of reductions in consulting; conventions and tradeshows; marketing and advertising; payroll, benefits and share-based compensation; and travel expenses.

Despite a 37% reduction in sales and marketing expenses, overall sales remains unchanged during the nine months ended March 31, 2011 compared to the nine months ended March 31, 2010. Management attributes the unchanged sales to the increased acceptance of the product particularly in the treatment of new body sites. Overall, the reduction in sales and marketing expense did not adversely affect the revenue of the Company. Management believes that it has right sized the sales staff to the current market conditions and will consider expanding the staff when the current staff does not have the capacity to service their existing customer base while making new sales calls on qualified new customers.

Projected Fiscal Year 2011 Liquidity and Capital Resources

At March 31, 2011, the Company held cash and cash equivalents of $2,667,269 as compared to $1,678,869 of cash and cash equivalents at June 30, 2010.

The Company had approximately $2.62 million of cash and cash equivalents and no short-term investments as of May 10, 2011. The Company’s monthly required cash operating expenditures were approximately $202,000 in the nine months ended March 31, 2011, which represents a 26% decrease of approximately $72,000 from average monthly cash operating expenditures for the nine months ended March 31, 2010, which is primarily a result of continued improvement in operating performance from fiscal year 2010 to fiscal year 2011. Management believes that less than $200,000 will be spent on capital expenditures for the fiscal year 2011 as research and development activities to return GliaSite to market continue to require the purchase of equipment that will be utilized in production activities upon successful completion of the FDA Form 510(k), however, there is no assurance that unanticipated needs for capital equipment may not arise.

The Company has a single remaining loan facility outstanding with HAEIFC, with a principal balance of approximately $142,000, of which approximately $54,000 will be due in the next 12 months.

The Company intends to continue its existing protocol studies and to begin new protocol studies on lung cancer treatment using Cesium-131. The Company continues to believe that approximately $100,000 in expense will be incurred during fiscal year 2011 related to protocol expenses relating to lung cancer and dual therapy and mono therapy prostate protocols.

Based on the foregoing assumptions, management believes cash, cash equivalents, and short-term investments on hand at March 31, 2011 will be sufficient to meet our anticipated cash requirements for operations, debt service, and capital expenditure requirements through at least the next twelve months.

Management plans to attain breakeven and generate additional cash flows by increasing revenues from both new and existing customers (through our direct sales channels and through our distributors), expanding into other market applications which initially will include head and neck, colorectal and lung implants while maintaining the Company's focus on cost control. However, there can be no assurance that the Company will attain profitability or that the Company will be able to attain increases in its revenue. Sales in the prostate market have not shown the increases necessary to breakeven during the past three fiscal years and did not improve during the nine months ended March 31, 2011. However, during the three months ended March 31, 2011 the prostate market did increase 8% over the three months ended March 31, 2010 and overall revenue increased 17% as a result of the expansion into other treatment modalities for the same periods of comparison. For the nine months ended March 31, 2011, revenue from other treatment modalities has increased 221% when compared to the nine months ended March 31, 2010. As management is now focused on expanding into head and neck, colorectal and lung applications, management believes the Company will need to raise additional capital for protocols, marketing staff, production staff and production equipment as it attempts to gain market share.

The Company expects to finance its future cash needs through sales of equity, possible strategic collaborations, debt financing or through other sources that may be dilutive to existing shareholders Management anticipates that if it raises additional financing that it will be at a discount to the market price and it will be dilutive to shareholders. Of course, funding may not be available to it on acceptable terms, or at all. If the Company is unable to raise additional funds, it may be unable to expand into new applications and may need to curtail operations.

Long-Term Debt

IsoRay has a single loan facility in place as of March 31, 2011 from the Hanford Area Economic Investment Fund Committee (HAEIFC), which was originated in June 2006. The loan originally had a total facility of $1,400,000 which was reduced in September 2007 to the amount of the Company’s initial draw of $418,670. The loan bears interest at five and one-half percent and the principal balance owed as of March 31, 2011 was $141,661. This loan is secured by receivables, equipment, materials and inventory, and certain life insurance policies and also required personal guarantees.

Other Commitments and Contingencies

The Company is subject to various local, state, and federal environmental regulations and laws due to the isotopes used to produce the Company’s product. As part of normal operations, amounts are expended to ensure that the Company is in compliance with these laws and regulations. While there have been no reportable incidents or compliance issues, the Company believes that if it relocates its current production facilities then certain decommissioning expenses will be incurred. An asset retirement obligation was established in the first quarter of fiscal year 2008 for the Company’s obligations at its current production facility. This asset retirement obligation will be for obligations to remove any residual radioactive materials and to remove all leasehold improvements.

The industry that the Company operates in is subject to product liability litigation. Through its production and quality assurance procedures, the Company works to mitigate the risk of any lawsuits concerning its product. The Company also carries product liability insurance to help protect it from this risk.

The Company previously disclosed a contingency related to its research and development project underway in the Ukraine to develop a proprietary separation process to manufacture enriched barium. As the prototype has not been successfully demonstrated and is not expected to be, the Company does not intend to make the final payment to the contractor, as the final payment was only due following a successful demonstration of the prototype.

The Company has no off-balance sheet arrangements.

ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As a smaller reporting company, the Company is not required to provide Part I, Item 3 disclosure in this Quarterly Report.

ITEM 4 – CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the design and operation of our disclosure controls and procedures, as such term is defined under Rules 13a-14(c) and 15d-14(c) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of March 31, 2011. Based on that evaluation, our principal executive officer and our principal financial officer concluded that the design and operation of our disclosure controls and procedures were effective. The design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. However, management believes that our system of disclosure controls and procedures is designed to provide a reasonable level of assurance that the objectives of the system will be met.

Changes in Internal Control over Financial Reporting

There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The Company is continuing the process of developing and implementing the remediation plan to address the material weakness and significant deficiency identified in its Form 10-K for the fiscal year ended June 30, 2010.

This plan is as follows:

The Company continues to assess opportunities to further segregated duties within a limited staff.

The staff is utilizing continuing professional education opportunities to enhance their knowledge.

Management is conducting ongoing reviews of all significant and non-routine transactions.

As a result of ongoing reviews of all significant and non-routine transactions, management believes that there are no material inaccuracies or omissions of material fact and to the best of its knowledge believes that the consolidated financial statements for the quarter ended March 31, 2011 fairly present in all material respects the financial condition and results of operations for the Company in conformity with U.S generally accepted accounting principles.

The NYSE Amex will consider delisting a company's securities if, among other things, the company fails to maintain minimum stockholder's equity or the company has sustained losses which are so substantial in relation to its overall operations or its existing financial resources, or its financial condition has become so impaired that it appears questionable, in the opinion of the NYSE Amex, as to whether such issuer will be able to continue operations and/or meet its obligations as they mature. As of the quarter ended March 31, 2011, IsoRay met the minimum stockholder’s equity requirement of $6 million needed to maintain its listing, primarily as a result of amending a provision in its outstanding amended and restated Series C warrant and exercise of the Series A warrant. Based on our current monthly expenses, management believes we will meet the minimum equity requirement for the quarter ended June 30, 2011. In the event that our common stock is delisted from the NYSE Amex, trading, if any, in the common stock would be conducted in the over the counter market. As a result, our shareholders would likely find it more difficult to dispose of, or to obtain accurate quotations as to the market value of, our common stock.

The Price Of Our Common Stock May Be Adversely Affected By The Future Issuance And Sale Of Shares Of Our Common Stock Or Other Equity Securities, Or By Our Announcement That Such Issuances And Sales May Occur. We cannot predict the size of future issuances or sales of our common stock or other equity securities, including those made pursuant to the Company's November 2010 securities purchase agreement with an investor who purchased 2.25 million shares and warrants to purchase up to 4,041,667 shares of common stock, future acquisitions or capital raising activities, or the effect, if any, that such issuances or sales may have on the market price of our common stock. The issuance and sale of substantial amounts of common stock or other equity securities, or announcement that such issuances and sales may occur, could adversely affect the market price of our common stock.

Future Sales By Shareholders, Or The Perception That Such Sales May Occur, May Depress The Price Of Our Common Stock. The sale or availability for sale of substantial amounts of our shares in the public market, including shares issuable upon conversion of outstanding preferred stock or exercise of common stock warrants and options, or the perception that such sales could occur, could adversely affect the market price of our common stock and also could impair our ability to raise capital through future offerings of our shares. As of May 2, 2011, the Company had 26,367,985 outstanding shares of common stock, and the following additional shares were reserved for issuance: 2,146,372 shares upon exercise of outstanding options, 3,819,185 shares upon exercise of outstanding warrants, and 59,065 shares upon conversion of preferred stock. Any decline in the price of our common stock may encourage short sales, which could place further downward pressure on the price of our common stock and may impair our ability to raise additional capital through the sale of equity securities.

The Issuance Of Shares Upon Exercise Of Derivative Securities May Cause Immediate And Substantial Dilution To Our Existing Shareholders. The issuance of shares upon conversion of the preferred stock and the exercise of common stock warrants and options may result in substantial dilution to the interests of other shareholders since these selling shareholders may ultimately convert or exercise and sell all or a portion of the full amount issuable upon exercise. If all derivative securities were converted or exercised into shares of common stock, including the maximum number of warrants issuable in our November 2010 offering, there would be approximately 7,720,483 additional shares of common stock outstanding as a result. The issuance of these shares will have the effect of further diluting the proportionate equity interest and voting power of holders of our common stock.

We Have Ongoing Cash Requirements . IsoRay has generated material operating losses since inception. We expect to continue to experience significant net operating losses. Due to recent capital investments and substantial cost reductions, management believes cash and cash equivalents on hand will be sufficient to meet our anticipated cash requirements for operations, debt service, and capital expenditure requirements through December 31, 2011. Management now estimates that operational cashflow breakeven will be achieved at approximately $700,000 in monthly revenue. However, there is no assurance as to when break-even will occur. If we are unable to generate profits and unable to obtain additional financing to meet our working capital requirements, we may have to curtail our business.

We Rely Heavily On A Limited Number Of Suppliers. Some materials used in our products are currently available only from a limited number of suppliers. In fiscal 2010, approximately sixty-eight percent (68%) of our Cs-131 was supplied through UralDial from reactors located in Russia. Unless the Company substantially increases its purchase requirements resulting from significant increases in demand for its product, the cost of Cs-131 in Russia could increase from current pricing.

Reliance on any single supplier increases the risks associated with concentrating isotope production at a single reactor facility which can be subject to unanticipated shutdowns. Failure to obtain deliveries of Cs-131 from multiple sources could have a material adverse effect on seed production and there may be a delay before we could locate alternative suppliers beyond the three currently used.

We may not be able to locate additional suppliers outside of Russia capable of producing the level of output of cesium at the quality standards we require. Additional factors that could cause interruptions or delays in our source of materials include limitations on the availability of raw materials or manufacturing performance experienced by our suppliers and a breakdown in our commercial relations with one or more suppliers. Some of these factors may be completely out of our and our suppliers' control.

Virtually all titanium tubing used in brachytherapy seed manufacture comes from a single source, Accellent Corporation. We currently obtain a key component of our seed core from another single supplier. We do not have formal written agreements with Accellent Corporation. Any interruption or delay in the supply of materials required to produce our products could harm our business if we were unable to obtain an alternative supplier or substitute equivalent materials in a cost-effective and timely manner. To mitigate any potential interruptions, the Company continually evaluates its inventory levels and management believes that the Company maintains a sufficient quantity on hand to alleviate any potential disruptions.

We Have Entered Into An Agreement With A Single Distributor For Our Cesium-131 From Russia. In December 2009, the Company entered into a new agreement with UralDial to purchase Cs-131 directly from UralDial which has been renewed through December 31, 2011 instead of directly from Institute of Nuclear Materials (INM) and Research Institute of Atomic Reactors (RIAR) as the Company had done prior to the original agreement with UralDial in December 2008. As a result, the Company continues to rely on UralDial to obtain Cs-131 from Russian sources. UralDial has agreed to maintain at least two Russian sources of its Cs-131 and through the UralDial agreement we have obtained set pricing for our Russian Cs-131 through the end of 2011. There can be no guarantee that UralDial will always be able to supply us with sufficient Cs-131 or will renew our existing contract on favorable terms in December 2011, which could be due in part to risks associated with foreign operations and beyond our and UralDial's control. If we were unable to obtain supplies of isotopes from Russia in the future, our overall supply of Cs-131 would be reduced significantly unless we have a source of enriched barium for utilization in domestic reactors.

We Are Subject To Uncertainties Regarding Reimbursement For Use Of Our Products. Hospitals and freestanding clinics may be less likely to purchase our products if they cannot be assured of receiving favorable reimbursement for treatments using our products from third-party payers, such as Medicare and private health insurance plans. Currently, Medicare reimburses hospitals at fixed rates that cover the cost of stranded and loose seeds. Clinics and physicians performing procedures in a free standing center are reimbursed at the actual cost of the seeds. It is expected that CMS will continue to reimburse providers using this same methodology in 2011.

In 2003, IsoRay applied to the CMS and received a reimbursement code for our Cs-131 seed. On July 1, 2007, CMS revised the coding system for brachytherapy seeds and separated the single code into two codes – one code for loose seeds and a second code for stranded seeds. This methodology was applied to all companies manufacturing brachytherapy seeds. Reimbursement amounts are reviewed and revised annually based upon information submitted to CMS on claims by providers. Although no changes are anticipated for 2011, adjustments can be made to reimbursement amounts or coverage policies, which could result in changes to reimbursement for brachytherapy services. These changes can positively or negatively affect market demand for our products. We monitor these changes and provide comments, as permitted, when changes are proposed, prior to implementation.

In July 2010, CMS published proposed changes for both reimbursement programs for government fiscal year 2011. No changes in reimbursement have been proposed by CMS for 2011. If the proposed changes are finalized, as expected in November 2010, there will be no changes in CMS reimbursement for 2011 but there is no assurance this will occur and is subject to revision annually.

Historically, private insurers have followed Medicare guidelines in establishing reimbursement rates. However, third-party payers are increasingly challenging the pricing of certain medical services or devices, and we cannot be sure that they will reimburse our customers at levels sufficient for us to maintain favorable sales and price levels for our products. There is no uniform policy on reimbursement among third-party payers, and we can provide no assurance that our products will continue to qualify for reimbursement from all third-party payers or that reimbursement rates will not be reduced. A reduction in or elimination of third-party reimbursement for treatments using our products would likely have a material adverse effect on our revenues.

Furthermore, any federal and state efforts to reform government and private healthcare insurance programs, such as those passed by the federal government in 2010, could significantly affect the purchase of healthcare services and products in general and demand for our products in particular. Medicare is the payer in approximately 70% of all U.S. prostate brachytherapy cases and management anticipates this percentage to increase annually. We are unable to predict whether potential healthcare reforms will be enacted, whether other healthcare legislation or regulations affecting the business may be proposed or enacted in the future or what effect any such legislation or regulations would have on our business, financial condition or results of operations.

If We Are Unable To Successfully Address The Material Weakness In Our Internal Controls, Our Ability To Report Our Financial Results On A Timely And Accurate Basis May Be Adversely Affected . Effective internal controls are necessary for us to provide reliable financial reports and effectively prevent fraud. If we cannot provide reliable financial reports or prevent fraud, our reputation and operating results could be harmed. We have in the past discovered, and may in the future discover, areas of our internal controls that need improvement. In its assessment of the effectiveness in internal control over financial reporting as of June 30, 2010, the Company determined that there were deficiencies that constituted a material weakness. Specifically, the Company did not maintain a sufficient complement of personnel with the appropriate level of knowledge, experience and training to analyze, review and monitor the accounting of complex financial transactions. As a result, the Company did not prepare adequate contemporaneous documentation that would provide a sufficient basis for an effective evaluation and review of the accounting for complex transactions that are significant or non-routine. This material weakness resulted in errors in the preliminary June 30, 2010 consolidated financial statements and more than a remote likelihood that a material misstatement of the Company's annual or interim financial statements would not be prevented or detected. The Company is in the process of developing and implementing a remediation plan to address the material weakness described above, along with the deficiencies also identified in the assessment, which are described in our Annual Report on Form 10-K filed with the SEC on September 28, 2010. Specifically, the Company continues to assess opportunities to address issues with segregation of duties, staff has received additional professional education, management conducts ongoing reviews of all significant and non-routine transactions, and the Company is assessing additional steps that may be taken in the remainder of fiscal year 2011 to improve internal controls. We cannot be certain that these measures will ensure that we implement and maintain adequate controls over our financial processes and reporting in the future and had not improved the process as of March 31, 2011. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to meet our reporting obligations. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our stock.

Certain Provisions of Minnesota Law and Our Charter Documents Have an Anti-Takeover Effect. There exist certain mechanisms under Minnesota law and our charter documents that may delay, defer or prevent a change of control. Anti-takeover provisions of our articles of incorporation, bylaws and Minnesota law could diminish the opportunity for shareholders to participate in acquisition proposals at a price above the then-current market price of our common stock. For example, while we have no present plans to issue any preferred stock, our Board of Directors, without further shareholder approval, may issue shares of undesignated preferred stock and fix the powers, preferences, rights and limitations of such class or series, which could adversely affect the voting power of the common shares. In addition, our bylaws provide for an advance notice procedure for nomination of candidates to our Board of Directors that could have the effect of delaying, deterring or preventing a change in control. Further, as a Minnesota corporation, we are subject to provisions of the Minnesota Business Corporation Act, or MBCA, regarding "business combinations," which can deter attempted takeovers in certain situations. Pursuant to the terms of a shareholder rights plan adopted in February 2007, each outstanding share of common stock has one attached right. The rights will cause substantial dilution of the ownership of a person or group that attempts to acquire the Company on terms not approved by the Board of Directors and may have the effect of deterring hostile takeover attempts. We amended our shareholder rights plan to permit the issuance of the common stock and warrants to the investor in the November 2010 offering and therefore the investor may acquire up to 25% of our outstanding common stock. The effect of these anti-takeover provisions may be to deter business combination transactions not approved by our Board of Directors, including acquisitions that may offer a premium over the market price to some or all shareholders. We may, in the future, consider adopting additional anti-takeover measures. The authority of our Board to issue undesignated preferred or other capital stock and the anti-takeover provisions of the MBCA, as well as other current and any future anti-takeover measures adopted by us, may, in certain circumstances, delay, deter or prevent takeover attempts and other changes in control of the Company not approved by our Board of Directors.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Use of Proceeds from Registered Securities

On October 27, 2009, we filed a registration statement on Form S-3 to register securities up to $15 million in value for future issuance in our capital raising activities. The registration statement became effective on November 13, 2009, and the commission file number assigned to the registration statement is 333-162694.

On April 22, 2010 we entered into a Sales Agreement (the “Agreement”) with C.K. Cooper & Company, Inc. (“CKCC”), which was amended on July 29, 2010. On October 1, 2010 the Company instructed CKCC to commence sales via placement notice permitting “at the market” sales of common stock through October 31, 2010. CKCC sold 304,227 shares of common stock on behalf of the Company receiving $250,632 in equity net of offering costs of $118,149 ($7,301 in commissions, $110,276 in legal and accounting expenses, and $571 in other costs). The offering of Shares pursuant to the Agreement, as amended, terminated on December 31, 2010.

On November 22, 2010, a securities purchase agreement was executed between an institutional investor and the Company for 2,250,000 shares of common stock with Aurora Capital acting as the placement agent for the transaction. As part of the transaction, the investor received four series of warrants (collectively, the "Warrants") The Series A and Series C Warrants were amended and restated via an Amendment Agreement dated December 27, 2010, and the Series C Warrants were further amended and restated via an Amendment Agreement dated March 31, 2011.

The Shares and Warrants were issued pursuant to the Company's shelf registration statement (the "Registration Statement") on Form S-3 (File No. 333-162694), which became effective on November 13, 2009, and prospectus supplements filed on November 24, 2010 and on December 29, 2010.

By letter agreement dated October 27, 2010, LifeTech Capital, a division of Aurora Capital, LLC, acted as placement agent in connection with the placement of the securities in the November 2010 offering. LifeTech received a cash fee of 5% of the gross proceeds received under the offering (excluding proceeds received on the exercise of C or D Warrants), and also received warrants to purchase 3% of the common stock sold in the offering and 3% of the Series A, B and C Warrants exercised at any time, which warrants issued to LifeTech shall not be exercisable for six months following the closing, shall have a five year term, and an exercise price of $1.56 per share.

The November 2010 offering yielded net cash of $2,026,255 which was net of offering costs of $223,745 ($112,500 of commission expense, $108,927 of legal and accounting expense and $2,318 of other costs). Warrant liabilities that total $1,724,000 were established related to Series A, B, and C warrants. Deferred financing costs of $193,051 were established related to the warrant liabilities for Series A, B, and C warrants.

The Series A warrants were exercised on March 24, 2011 for 538,660 shares of common stock in exchange for $475,000 net of commission expense.

There was no material change in the use of proceeds from our public offering as described in our final prospectus filed with the SEC pursuant to Rule 424 (b). Through March 31, 2011 we had not used any of the net proceeds and invested the net proceeds in cash and cash equivalents.
