HESKA CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2012

(UNAUDITED)

1. ORGANIZATION AND BUSINESS

Heska Corporation ("Heska" or the "Company") develops, manufactures, markets, sells and supports veterinary products. Heska's core focus is on the canine and feline companion animal health markets.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements are the responsibility of the Company's management and have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the instructions to Form 10-Q and rules and regulations of the Securities and Exchange Commission (the "SEC"). The condensed consolidated balance sheet as of March 31, 2012, the condensed consolidated statements of income for the three months ended March 31, 2011 and 2012 and the condensed consolidated statements of cash flows for the three months ended March 31, 2011 and 2012 are unaudited, but include, in the opinion of management, all adjustments (consisting of normal recurring adjustments) which the Company considers necessary for a fair presentation of its financial position, operating results and cash flows for the periods presented. All material intercompany transactions and balances have been eliminated in consolidation. Although the Company believes that the disclosures in these financial statements are adequate to make the information presented not misleading, certain information and footnote disclosures normally included in complete financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the SEC.

Results for any interim period are not necessarily indicative of results for any future interim period or for the entire year. The accompanying financial statements and related disclosures have been prepared with the presumption that users of the interim financial information have read or have access to the audited financial statements for the preceding fiscal year. Accordingly, these financial statements should be read in conjunction with the audited financial statements and the related notes thereto for the year ended December 31, 2011, included in the Company's Annual Report on Form 10-K filed with the SEC on February 28, 2012.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenue and expense during the reported period. Actual results could differ from those estimates. Significant estimates are required when establishing the allowance for doubtful accounts and the provision for excess/obsolete inventory, in determining the period over which the Company's obligations are fulfilled under agreements to license product rights and/or technology rights, in determining the need for, and the amount of, a valuation allowance on certain deferred tax assets and in determining the need for, and the amount of, an accrued liability for future payments related to minimum purchase obligations the Company may make in order to maintain certain product rights.

-6-

Inventories

Inventories are stated at the lower of cost or market using the first-in, first-out method. Inventory manufactured by the Company includes the cost of material, labor and overhead. If the cost of inventories exceeds estimated fair value, provisions are made to reduce the carrying value to estimated fair value.

Inventories, net consist of the following (in thousands):

	December 31, 2011			March 31, 2012

Raw materials	$	5,580		$	4,915
Work in process		2,505			3,601
Finished goods		5,043			5,004
Allowance for excess or obsolete inventory		(727	)		(756	)
	$	12,401		$	12,764

Basic and Diluted Net Income Per Share

Basic net income per common share is computed using the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the sum of the weighted average number of shares of common stock outstanding, and, if not anti-dilutive, the effect of outstanding common stock equivalents (such as stock options and warrants) determined using the treasury stock method. For the three months ended March 31, 2012 and 2011, the Company reported net income and therefore, dilutive common stock equivalent securities, as computed using the treasury method, were added to basic weighted average shares outstanding for the period to derive the weighted average shares for diluted earnings per share calculation. Common stock equivalent securities that were anti-dilutive for the three months ended March 31, 2012 and 2011, and therefore excluded, were outstanding options to purchase 697,503 and 1,138,983 shares of common stock, respectively. These securities are anti-dilutive primarily due to exercise prices greater than the average trading price of the Company's common stock during the three months ended March 31, 2012 and 2011, respectively.

3. CAPITAL STOCK

The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model, with the following weighted average assumptions for options granted in the three months ended March 31, 2011 and 2012.

	Three Months Ended March 31,
	2011	2012

Risk-free interest rate	1.00%		0.56%
Expected lives	3.0 years		3.0 years
Expected volatility	82%		60%
Expected dividend yield	0%		3.43%

A summary of the Company's stock option plans, excluding options to purchase fractional shares resulting from the Company's December 2010 1-for-10 reverse stock split is as follows:

		Year Ended December 31, 2011					Three Months Ended March 31, 2012
		Options		Weighted Average Exercise Price			Options	Weighted Average Exercise Price
Outstanding at beginning of period			1,341,876		$	11.003	1,448,675		$	10.425
	Granted at market		187,750		$	6.962	3,250		$	11.650
	Cancelled		(73,871	)	$	12.684	(112,420)		$	11.370
	Exercised		(7,080	)	$	4.564	(106,110)		$	5.091
Outstanding at end of period			1,448,675		$	10.425	1,233,395		$	10.801
Exercisable at end of period			1,175,731		$	11.427	984,319		$	11.972

The estimated fair value of stock options granted during the three months ended March 31, 2012 and 2011 was computed to be approximately $13 thousand and $800, respectively. The amount is amortized ratably over the vesting period of the options. The per share weighted average estimated fair value of options granted during the three months ended March 31, 2012 and 2011 was computed to be approximately $3.91 and $3.21, respectively. The total intrinsic value of options exercised during the three months ended March 31, 2012 and 2011 was approximately $652 thousand and $1 thousand, respectively. The cash proceeds from options exercised during the three months ended March 31, 2012 and 2011 were approximately $184 thousand and $15 thousand, respectively.

The following table summarizes information about stock options outstanding and exercisable at March 31, 2012, excluding outstanding options to purchase an aggregate of 106.7 fractional shares resulting from the Company's December 2010 1-for-10 reverse stock split with a weighted average remaining contractual life of 2.60 years, a weighted average exercise price of $13.61 and exercise prices ranging from $3.40 to $31.50. The Company intends to issue whole shares only from option exercises.

	Options Outstanding						Options Exercisable
Exercise Prices	Number of Options Outstanding at March 31, 2012		Weighted Average Remaining Contractual Life in Years		Weighted Average Exercise Price		Number of Options Exercisable at March 31, 2012		Weighted Average Exercise Price
$ 2.70 - $ 6.66		251,192		7.37	$	4.790		151,032		$	4.813
$ 6.76 - $ 7.00		249,722		5.98	$	6.913		114,588		$	6.970
$ 7.10 - $11.00		256,740		3.56	$	9.009		246,271		$	9.004

$ 2.70 - $31.50		1,233,395		4.87	$	10.801		984,319		$	11.972

As of March 31, 2012, there was approximately $647 thousand of total unrecognized compensation cost related to outstanding stock options. That cost is expected to be recognized over a weighted average period of 1.9 years, with approximately $182 thousand to be recognized in the nine months ending December 31, 2012 and all the cost to be recognized as of March 2016, assuming all options vest according to the vesting schedules in place at March 31, 2012. As of March 31, 2012, the aggregate intrinsic value of outstanding options was approximately $3.4 million and the aggregate intrinsic value of exercisable options was approximately $2.1 million.

4. SEGMENT REPORTING

The Company is comprised of two reportable segments, Core Companion Animal Health ("CCA") and Other Vaccines, Pharmaceuticals and Products ("OVP"). The CCA segment includes diagnostic instruments and supplies, as well as single use diagnostic and other tests, pharmaceuticals and vaccines, primarily for canine and feline use. These products are sold directly by the Company as well as through other distribution relationships. CCA segment products manufactured at the Des Moines, Iowa production facility included in our OVP segment's assets are transferred at cost and are not recorded as revenue for our OVP segment. The OVP segment includes private label vaccine and pharmaceutical production, primarily for cattle, but also for other animals including small mammals and fish. All OVP products are sold by third parties under third-party labels.

Summarized financial information concerning the Company's reportable segments is shown in the following table (in thousands):

MANAGEMENT'S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with "Selected Consolidated Financial Data" and the Unaudited Condensed Consolidated Financial Statements and related Notes included in Part I Item 1 of this Form 10-Q.

This discussion contains forward-looking statements that involve risks and uncertainties. Such statements, which include statements concerning future revenue sources and concentration, gross profit margins, selling and marketing expenses, general and administrative expenses, research and development expenses, capital resources, capital expenditures and additional financings or borrowings, are subject to risks and uncertainties, including, but not limited to, those discussed below and elsewhere in this Form 10-Q, particularly in Part II Item 1A. "Risk Factors," that could cause actual results to differ materially from those projected. The forward-looking statements set forth in this Form 10-Q are as of the close of business on May 10, 2012, and we do not intend to update this forward-looking information.

Overview

We develop, manufacture, market, sell and support veterinary products. Our business is comprised of two reportable segments, Core Companion Animal Health ("CCA"), which represented 83% of our revenue for the twelve months ended March 31, 2012 (which we define as "LTM") and Other Vaccines, Pharmaceuticals and Products ("OVP"), which represented 17% of LTM revenue.

The CCA segment includes diagnostic instruments and supplies as well as single use diagnostic and other tests, pharmaceuticals and vaccines, primarily for canine and feline use.

Diagnostic instruments and supplies represented approximately 41% of our LTM revenue. Many products in this area involve placing an instrument in the field and generating future revenue from consumables, including items such as supplies and service, as that instrument is used. Approximately 31% of our LTM revenue resulted from the sale of such consumables to an installed base of instruments and approximately 10% of our revenue was from new hardware sales. A loss of or disruption in supply of consumables we are selling to an installed base of instruments could substantially harm our business. All of our diagnostic instruments and supplies are supplied by third parties, who typically own the product rights and supply the product to us under marketing and/or distribution agreements. In many cases, we have collaborated with a third party to adapt a human instrument for veterinary use. Major products in this area include our chemistry instruments, our hematology instruments and our new blood gas instruments and their affiliated operating consumables. Revenue from products in these three areas, including revenues from consumables, represented approximately 37% of our LTM revenue.

Other CCA revenue, including single use diagnostic and other tests, pharmaceuticals and vaccines as well as research and development, licensing and royalty revenue, represented approximately 41% of our LTM revenue. Since items in this area are often single use by their nature, our typical aim is to build customer satisfaction and loyalty for each product, generate repeat annual sales from existing customers and expand our customer base in the future. Products in this area are both supplied by third parties and provided by us. Major products in this area include our heartworm diagnostic tests, our heartworm preventive, our allergy test kits, our allergy immunotherapy and our allergy diagnostic tests. Combined revenue from heartworm-related products and allergy-related products represented approximately 36% of our LTM revenue.

We consider the CCA segment to be our core business and devote most of our management time and other resources to improving the prospects for this segment. Maintaining a continuing, reliable and economic supply of products we currently obtain from third parties is critical to our success in this area. Virtually all of our sales and marketing expenses occur in the CCA segment. The majority of our research and development spending is dedicated to this segment as well.

-10-

All our CCA products are ultimately sold primarily to or through veterinarians. In many cases, veterinarians will mark up their costs to the end user. The acceptance of our products by veterinarians is critical to our success. CCA products are sold directly to end users by us as well as through distribution relationships, such as our corporate agreement with Schering-Plough Animal Health Corporation ("SPAH"), a unit of Merck & Co., Inc. ("Merck"), the sale of kits to conduct blood testing to third-party veterinary diagnostic laboratories and independent third-party distributors. Revenue from direct sales and distribution relationships represented approximately 69% and 31%, respectively, of CCA LTM revenue.

We intend to sustain profitability over the long term through a combination of revenue growth, gross margin improvement and expense control. Accordingly, we closely monitor revenue growth trends in our CCA segment. Revenue in this segment increased 1% for the three months ended March 31, 2012 as compared to the three months ended March 31, 2011. We believe poor economic conditions over the past several years have impacted our revenue as, for example, veterinarians have continued to delay or defer capital expenditures on new diagnostic instrumentation.

The OVP segment includes our 168,000 square foot USDA- and FDA-licensed production facility in Des Moines, Iowa. We view this facility as a strategic asset which will allow us to control our cost of goods on any vaccines and pharmaceuticals that we may commercialize in the future. We are increasingly integrating this facility with our operations elsewhere. For example, virtually all our U.S. inventory is now stored at this facility and fulfillment logistics are managed there. CCA segment products manufactured at this facility are transferred at cost and are not recorded as revenue for our OVP segment. We view OVP reported revenue as revenue primarily to cover the overhead costs of the facility and to generate incremental cash flow to fund our CCA segment.

Our OVP segment includes private label vaccine and pharmaceutical production, primarily for cattle but also for other animals such as small mammals. All OVP products are sold by third parties under third-party labels.

We have developed our own line of bovine vaccines that are licensed by the USDA. We have a long-term agreement with a distributor, Agri Laboratories, Ltd., ("AgriLabs"), for the marketing and sale of certain of these vaccines which are sold primarily under the Titanium® and MasterGuard® brands which are registered trademarks of AgriLabs. This agreement generates a significant portion of our OVP segment's revenue. Our OVP segment also produces vaccines and pharmaceuticals for other third parties.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon the consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenue and expense during the periods. These estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. We have identified those critical accounting policies used in reporting our financial position and results of operations based upon a consideration of those accounting policies that involve the most complex or subjective decisions or assessment. We consider the following to be our critical policies.

Revenue Recognition

We generate our revenue through the sale of products, as well as through licensing of technology product rights, royalties and sponsored research and development. Our policy is to recognize revenue when the applicable revenue recognition criteria have been met, which generally include the following:

-11-

·	Persuasive evidence of an arrangement exists;

·	Delivery has occurred or services rendered;

·	Price is fixed or determinable; and

·	Collectability is reasonably assured.

Revenue from the sale of products is recognized after both the goods are shipped to the customer and acceptance has been received, if required, with an appropriate provision for estimated returns and allowances. We do not permit general returns of products sold. Certain of our products have expiration dates. Our policy is to exchange certain outdated, expired product with the same product. We record an accrual for the estimated cost of replacing the expired product expected to be returned in the future, based on our historical experience, adjusted for any known factors that reasonably could be expected to change historical patterns, such as regulatory actions which allow us to extend the shelf lives of our products. Revenue from both direct sales to veterinarians and sales to independent third-party distributors are generally recognized when goods are shipped. Our products are shipped complete and ready to use by the customer. The terms of the customer arrangements generally pass title and risk of ownership to the customer at the time of shipment. Certain customer arrangements provide for acceptance provisions. Revenue for these arrangements is not recognized until the acceptance has been received or the acceptance period has lapsed. We reduce our revenue by the estimated cost of any rebates, allowances or similar programs, which are used as promotional programs.

Recording revenue from the sale of products involves the use of estimates and management judgment. We must make a determination at the time of sale whether the customer has the ability to make payments in accordance with arrangements. While we do utilize past payment history, and, to the extent available for new customers, public credit information in making our assessment, the determination of whether collectability is reasonably assured is ultimately a judgment decision that must be made by management. We must also make estimates regarding our future obligation relating to returns, rebates, allowances and similar other programs.

License revenue under arrangements to sell or license product rights or technology rights is recognized as obligations under the agreement are satisfied, which generally occurs over a period of time. Generally, licensing revenue is deferred and recognized over the estimated life of the related agreements, products, patents or technology. Nonrefundable licensing fees, marketing rights and milestone payments received under contractual arrangements are deferred and recognized over the remaining contractual term using the straight-line method.

Recording revenue from license arrangements involves the use of estimates. The primary estimate made by management is determining the useful life of the related agreement, product, patent or technology. We evaluate all of our licensing arrangements by estimating the useful life of either the product or the technology, the length of the agreement or the legal patent life and defer the revenue for recognition over the appropriate period.

Occasionally we enter into arrangements that include multiple elements. Such arrangements may include the licensing of technology and manufacturing of product. In these situations we must determine whether the various elements meet the criteria to be accounted for as separate elements. If the elements cannot be separated, revenue is recognized once revenue recognition criteria for the entire arrangement have been met or over the period that the Company's obligations to the customer are fulfilled, as appropriate. If the elements are determined to be separable, the revenue is allocated to the separate elements based on relative fair value and recognized separately for each element when the applicable revenue recognition criteria have been met. In accounting for these multiple element arrangements, we must make determinations about whether elements can be accounted for separately and make estimates regarding their relative fair values.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts receivable based on client-specific allowances, as well as a general allowance. Specific allowances are maintained for clients which are determined to have a high degree of collectability risk based on such factors, among others, as: (i) the aging of the accounts receivable balance; (ii) the client's past payment history; (iii) a deterioration in the client's financial condition, evidenced by weak financial condition and/or continued poor operating results, reduced credit ratings, and/or a bankruptcy filing. In addition to the specific allowance, the Company maintains a general allowance for credit risk in its accounts receivable which is not covered by a specific allowance. The general allowance is established based on such factors, among others, as: (i) the total balance of the outstanding accounts receivable, including considerations of the aging categories of those accounts receivable; (ii) past history of uncollectable accounts receivable write-offs; and (iii) the overall creditworthiness of the client base. A considerable amount of judgment is required in assessing the realizability of accounts receivable. Should any of the factors considered in determining the adequacy of the overall allowance change, an adjustment to the provision for doubtful accounts receivable may be necessary.

Inventories

Inventories are stated at the lower of cost or market, cost being determined on the first-in, first-out method. Inventories are written down if the estimated net realizable value of an inventory item is less than its recorded value. We review the carrying cost of our inventories by product each quarter to determine the adequacy of our reserves for excess/obsolescence inventory. In accounting for inventories we must make estimates regarding the estimated net realizable value of our inventory. This estimate is based, in part, on our forecasts of future sales and shelf life of product.

Deferred Tax Assets – Valuation Allowance

Our deferred tax assets, such as a domestic Net Operating Loss ("NOL"), are reduced by an offsetting valuation allowance based on judgmental assessment of available evidence if we are unable to conclude that it is more likely than not that some or all of the related deferred tax assets will be realized. If we are able to conclude it is more likely than not that we will realize a future benefit from a deferred tax asset, we will reduce the related valuation allowance by an amount equal to the estimated quantity of income taxes we would pay in cash if we were not to utilize the deferred tax asset in the future. The first time this occurs in a given jurisdiction, it will result in a net deferred tax asset on our balance sheet and an income tax benefit of equal magnitude in our statement of income in the period we make the determination. In future periods, we will then recognize as income tax expense the estimated quantity of income taxes we would have paid in cash had we not utilized the related deferred tax asset. The corresponding journal entry will be a reduction of our deferred tax asset. If there is a change regarding our tax position in the future, we will make a corresponding adjustment to the related valuation allowance.

Results of Operations

Revenue

Total revenue decreased 2% to $19.2 million for the three months ended March 31, 2012 as compared to $19.5 million in the corresponding period in 2011.

Revenue from our CCA segment was $16.6 million for the three months ended March 31, 2012, an increase of 1% as compared to $16.4 million for the corresponding period in 2011. Increased revenue from our instrument consumables, international allergy business and IV pumps, somewhat offset by lower revenue from our heartworm preventive, were factors in the increase.

-13-

Revenue from our OVP segment was $2.6 million for the three months ended March 31, 2012, a decrease of $469 thousand as compared to $3.1 million in the corresponding period in 2011. Lower sales of cattle vaccines to new 2011 customers were a key factor in the decrease.

We expect 2012 total revenue to increase as compared with 2011.

Cost of Revenue

Cost of revenue totaled $10.3 million for the three months ended March 31, 2012, a decrease of $955 thousand or 9% as compared to $11.2 million for the corresponding period in 2011. Gross profit increased by $625 thousand to $8.9 million for the three months ended March 31, 2012 as compared to $8.3 million in the prior year period. Gross Margin, i.e. gross profit divided by total revenue, increased to 46.5% for the three months ended March 31, 2012 from 42.5% in the prior year period. A shift in product mix to relatively higher margin products was a factor in the increase.

We expect Gross Margin to increase in 2012 as compared to 2011.

Operating Expenses

Total operating expenses increased 16% to $7.8 million in the three months ended March 31, 2012 from $6.8 million in the prior year period.

Selling and marketing expenses increased 23% to $4.9 million in the three months ended March 31, 2012 as compared to $4.0 million in the corresponding period in 2011. Increased personnel and travel costs were key factors in the increase.

Research and development expenses were $334 thousand for the three months ended March 31, 2012, an increase of $3 thousand as compared to $331 thousand in the corresponding period in 2011. Payment related to new products was a factor in the increase.

General and administrative expenses were $2.6 million in the three months ended March 31, 2012, up 6% from $2.5 million in the prior year period. Increased personnel costs were a factor in the increase.

We expect 2012 operating expenses will be higher than in 2011.

Interest and Other Expense, Net

Interest and other expense, net was $142 thousand in the three months ended March 31, 2012, an increase of $119 thousand as compared to $23 thousand in the prior year period. The largest factor in the change was related to larger currency loss recognition in the three months ended March 31, 2012.

We expect interest and other expense, net to be a net expense in 2012, as opposed to income in 2011, as we have experienced a larger currency loss through the first three months in 2012 than in 2011, we have a $100 thousand minimum interest expense under our asset-based revolving line of credit with Wells Fargo Bank, National Association ("Wells Fargo") and we do not anticipate we will experience interest income at the same level as in 2011, which resulted primarily from interest awarded in an arbitration judgment.

Income Tax Expense

We recognized an income tax expense of $356 thousand in the three months ended March 31, 2012, a $245 thousand change as compared to a tax expense of $601 thousand in the prior year period. The lower ratio of total tax expense compared to income before income taxes in the 2012 period results from the impact of non-tax deductible expenses, such as incentive stock option amortization, which tend to increase the ratio at lower income levels. As we believe we will have significantly higher income before income taxes in 2012 as compared to 2011, this ratio is accordingly lower in the 2012 period.

-14-

For the three months ended March 31, 2012, current tax expense was $48 thousand, a change of $26 thousand from $74 thousand in the prior year period. Higher income before income taxes in the 2011 period was a factor in the change. Current tax expense represents taxes we are expected to pay in cash as a result of a given period's operations.

For the three months ended March 31, 2012, deferred tax expense was $308 thousand, a $219 thousand change from $527 thousand in the three months ended March 31, 2011. Higher income before income taxes in the 2011 period was a factor in the change. Deferred tax expense primarily relates to our large domestic NOL position, which provides a tax shield for most federal income taxes we would otherwise pay.

In 2012, we expect higher income tax expense as opposed to 2011 as we expect higher income before income taxes in 2012 as compared to 2011.

Net Income

Net income was $584 thousand in the three months ended March 31, 2012, a decrease of approximately $332 thousand compared to $916 thousand in the prior year period. The change was primarily due to higher operating expenses, somewhat offset by higher Gross Margin.

We expect net income will be higher in 2012 than in 2011, primarily as a result of increased revenue and improved Gross Margin, somewhat offset by higher operating expenses.

Liquidity and Capital Resources

We have incurred net cumulative negative cash flow from operations since our inception in 1988. For the three months ended March 31, 2012, we had net income of $584 thousand. During the three months ended March 31, 2012, our operations used cash of approximately $255 thousand. At March 31, 2012, we had $6.0 million of cash and cash equivalents, $19.6 million of working capital, and $0 of outstanding borrowings under our revolving line of credit, discussed below.

Net cash used by operating activities was approximately $255 thousand for the three months ended March 31, 2012 as compared to $151 thousand of cash used by operating activities in the prior year period, a change of approximately $104 thousand. Major factors in the change were a $1.1 million increase in cash used by inventories as we increased inventories in the 2012 period while reducing inventories in the 2011 period, a $491 thousand increase in cash used by accrued liabilities as our accrued liabilities declined in the 2012 period while increasing in the 2011 period and a $332 thousand decline in net income, somewhat offset by a $2.0 million increase in cash provided by accounts payable as we experienced an increase in days payable in the 2012 period as compared to a decrease in the 2011 period and $758 thousand less cash used in accounts receivable as we experienced a decrease in days sales outstanding in the 2012 period as compared to an increase in the 2011 period. We believe we are in compliance with all contractual payment terms with our vendors and the increase in days payable, discussed above, is related to an accounts payable mix more heavily weighted toward vendors with longer payment terms.

Net cash flows used in investing activities were $271 thousand in the three months ended March 31, 2012, an increase of approximately $174 thousand compared to $97 thousand used during the corresponding period in 2011. Expenditures in this area were primarily for the purchase of property and equipment in both periods. The largest factor in the change was an increase in capital expenditure on furniture and fixtures, including a new trade show booth.

Net cash flows provided by financing activities were $184 thousand during the three months ended March 31, 2012, a $132 thousand change as compared to $316 thousand provided by financing activities during the corresponding period in 2011. The primary reason for the decline was $301 thousand dollars in cash provided under our revolving line of credit with Wells Fargo in the 2011 period but not the 2012 period, largely offset by $169 thousand in increased proceeds from the exercise of stock options.

-15-

At March 31, 2012, we had a $15.0 million asset-based revolving line of credit with Wells Fargo which has a maturity date of December 31, 2013 as part of our credit and security agreement with Wells Fargo. At March 31, 2012, we had no outstanding borrowings under this line of credit. Our ability to borrow under this facility varies based upon available cash, eligible accounts receivable and eligible inventory. On March 31, 2012, interest on borrowings due was to be charged at a stated rate of three month LIBOR plus 2.75% and payable monthly. We are required to comply with various financial and non-financial covenants, and we have made various representations and warranties under our agreement with Wells Fargo. Among the financial covenants is a requirement to maintain a minimum liquidity (cash plus excess borrowing base) of $1.5 million. Additional requirements include covenants for minimum capital monthly and minimum net income quarterly. Failure to comply with any of the covenants, representations or warranties could result in our being in default on the loan and could cause all outstanding amounts payable to Wells Fargo to become immediately due and payable or impact our ability to borrow under the agreement. We were in compliance with all financial covenants as of March 31, 2012. At March 31, 2012, we had $9.9 million of borrowing capacity based upon eligible accounts receivable and eligible inventory under our revolving line of credit.

In February 2012, our Board of Directors declared a cash dividend of $0.10 per share to the holders of our Public Common Stock on March 30, 2012 payable on April 10, 2012. In May 2012, our Board of Directors declared a cash dividend of $0.10 per share to the holders of our Public Common Stock on June 29, 2012 payable on July 10, 2012. We intend to pay a regular quarterly dividend of $0.10 per share of outstanding Public Common Stock for the foreseeable future at the discretion of our Board of Directors considering available cash, anticipated cash needs, overall financial condition, loan agreement restrictions, future prospects for earnings and cash flows, anticipated tax treatment as well as other relevant factors.

We would consider strategic acquisitions if we felt they were consistent with our strategic direction. Our Board of Directors has considered, and may consider in the near future, a stock buyback as an alternative use of our cash. Our primary known short-term need for capital, which is subject to change, is to fund our operations, which consist of continued sales and marketing, general and administrative and research and development efforts, working capital associated with increased product sales and capital expenditures relating to maintaining and developing our manufacturing operations. Our future liquidity and capital requirements will depend on numerous factors, including the extent to which our marketing and selling efforts, as well as those of third parties who market and sell our products, are successful in increasing our revenue, competition, the extent to which currently planned products and/or technologies are successfully developed, launched and sold, any changes required by regulatory bodies to maintain our operations and other factors.

Our financial plan for 2012 indicates that our available cash and cash equivalents, together with cash from operations will be sufficient to fund our operations through 2012 and into 2013. However, our actual results may differ from this plan, and we may be required to consider alternative strategies. We may be required to raise additional capital in the future. If necessary, we expect to raise these additional funds through borrowings under our revolving line of credit, the sale of equity securities or the issuance of new term debt secured by the same assets as term loans which were fully repaid in 2010. There is no guarantee that additional capital will be available from these sources on acceptable terms, if at all, and certain of these sources may require approval by existing lenders. If we cannot raise the additional funds through these options on acceptable terms or with the necessary timing, management could also reduce discretionary spending to decrease our cash burn rate through actions such as delaying or canceling budgeted hiring activities or marketing plans. These actions would likely extend the then available cash and cash equivalents, and then available borrowings to some degree.

Item 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of loss that may impact the financial position, results of operations or cash flows due to adverse changes in financial and commodity market prices and rates. We are exposed to market risk in the areas of changes in United States and foreign interest rates and changes in foreign currency exchange rates as measured against the United States dollar and against other foreign currency exchange rates. These exposures are directly related to our normal operating and funding activities.

Interest Rate Risk

At March 31, 2012, there was no debt outstanding on our line of credit with Wells Fargo. We also had approximately $6.0 million of cash and cash equivalents at March 31, 2012, the majority of which was invested in liquid interest bearing accounts. We had no interest rate hedge transactions in place on March 31, 2012. We completed an interest rate risk sensitivity analysis based on the above and an assumed one percentage point increase/decrease in interest rates. If market rates increase/decrease by one percentage point, we would experience a decrease/increase in annual net interest expense of approximately $60 thousand based on our outstanding balances as of March 31, 2012.

Foreign Currency Risk

Our investment in foreign assets consists primarily of our investment in our European subsidiary. Foreign currency risk may impact our results of operations. In cases where we purchase inventory in one currency and sell corresponding products in another, our gross margin percentage is typically at risk based on foreign currency exchange rates. In addition, in cases where we may be generating operating income in foreign currencies, the magnitude of such operating income when translated into U.S. dollars will be at risk based on foreign currency exchange rates. Our agreements with customers and suppliers vary significantly in regard to the existence and extent of currency adjustment and other currency risk sharing provisions. We had no foreign currency hedge transactions in place on March 31, 2012.

We have a wholly-owned subsidiary in Switzerland which uses the Swiss Franc as its functional currency. We purchase inventory in foreign currencies, primarily Japanese Yen and Euros, and sell corresponding products in U.S. dollars. We also sell products in foreign currencies, primarily Japanese Yen and Euros, where our inventory costs are in U.S. dollars. Based on our results of operations for the most recent twelve months, if foreign currency exchange rates were to strengthen/weaken by 25% against the dollar, we would expect a resulting pre-tax loss/gain of approximately $396 thousand.

CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures. Our management, with the participation of our chief executive officer and our chief financial officer, evaluated the effectiveness of our disclosure controls and procedures, as defined by Rule 13a-15 of the Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our chief executive officer and our chief financial officer have concluded that our disclosure controls and procedures are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control over Financial Reporting. There was no change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be involved in litigation relating to claims arising out of our operations. As of March 31, 2012, we were not a party to any legal proceedings that are expected, individually or in the aggregate, to have a material adverse effect on our business, financial condition or operating results.

Item 1A. Risk Factors

Our future operating results may vary substantially from period to period due to a number of factors, many of which are beyond our control. The following discussion highlights some of these factors and the possible impact of these factors on future results of operations. The risks and uncertainties described below are not the only ones we face. Additional risks or uncertainties not presently known to us or that we deem to be currently immaterial also may impair our business operations. If any of the following factors actually occur, our business, financial condition or results of operations could be harmed. In that case, the price of our common stock could decline and you could experience losses on your investment.

We may be unable to market and sell our products successfully.

We may not develop and maintain marketing and/or sales capabilities successfully, and we may not be able to make arrangements with third parties to perform these activities on satisfactory terms. If our marketing and sales strategy is unsuccessful, our ability to sell our products will be negatively impacted and our revenues will decrease. This could result in the loss of distribution rights for products or failure to gain access to new products and could cause damage to our reputation and adversely affect our business and future prospects.

We believe the recent worldwide economic weakness has had a negative effect on our business, and this may continue in the future. This is particularly notable in the sale of new instruments, which is a capital expenditure many, if not most, veterinarians may choose to defer in times of perceived economic weakness. Even if the overall economy begins to grow in the future, there may be a lag before veterinarians display confidence such growth will continue and return to historical capital expenditure purchasing patterns. As the vast majority of cash flow to veterinarians ultimately is funded by pet owners without private insurance or government support, our business may be more susceptible to severe economic downturns than other health care businesses which rely less on individual consumers.

The market for companion animal healthcare products is highly fragmented. Because our CCA proprietary products are generally available only to veterinarians or by prescription and our medical instruments require technical training to operate, we ultimately sell all our CCA products primarily to or through veterinarians. The acceptance of our products by veterinarians is critical to our success. Changes in our ability to obtain or maintain such acceptance or changes in veterinary medical practice could significantly decrease our anticipated sales.

We believe that one of our largest competitors, IDEXX Laboratories, Inc. (IDEXX"), currently in effect prohibits its distributors from selling competitive products, including our diagnostic instruments and heartworm diagnostic tests, which may hinder our ability to sell and market our products if these distributors are increasingly successful.

The loss of significant customers who, for example, are historically large purchasers or who are considered leaders in their field could damage our business and financial results.

No single customer accounted for more than 10% of consolidated revenue for the three months ended March 31, 2012. No single customer accounted for more than 10% of our consolidated accounts receivable at March 31, 2012. Revenue for Merck entities, including SPAH, represented approximately 20% of our consolidated revenue for the three months ended March 31, 2011. Revenue from Novartis entities represented approximately 12% of our total revenue for the three months ended March 31, 2011. No other single customer accounted for more than 10% of our total revenue for the three months ended March 31, 2011. Merck entities, including SPAH, accounted for 17% of our consolidated accounts receivable at March 31, 2011. No other single customer accounted for more than 10% of our consolidated accounts receivable at March 31, 2011.

-19-

We operate in a highly competitive industry, which could render our products obsolete or substantially limit the volume of products that we sell. This would limit our ability to compete and maintain sustained profitability.

The market in which we compete is intensely competitive. Our competitors include independent animal health companies and major pharmaceutical companies that have animal health divisions. We also compete with independent, third-party distributors, including distributors who sell products under their own private labels. In the point-of-care diagnostic testing market, our major competitors include IDEXX, Abaxis, Inc. ("Abaxis") and Synbiotics Corporation ("Synbiotics"), a company acquired by Pfizer Inc. ("Pfizer") in January 2011. The products manufactured by our OVP segment for sale by third parties compete with similar products offered by a number of other companies, some of which have substantially greater financial, technical, research and other resources than us and may have more established marketing, sales, distribution and service organizations than those of our OVP segment's customers. Competitors may have facilities with similar capabilities to our OVP segment, which they may operate and sell at a lower unit price to customers than our OVP segment does, which could cause us to lose customers. Companies with a significant presence in the companion animal health market, such as Bayer AG, CEVA Santé Animale, Eli Lilly and Company, Merck, Novartis AG, Pfizer, sanofi-aventis, Vétoquinol S.A. and Virbac S.A. may be marketing or developing products that compete with our products or would compete with them if developed. These and other competitors and potential competitors may have substantially greater financial, technical, research and other resources and larger, more established marketing, sales and service organizations than we do. Our competitors may offer broader product lines and have greater name recognition than we do. For example, if Pfizer is successful in integrating Synbiotics or devotes its significant commercial and financial resources to growing Synbiotics' market share, our sales could suffer significantly. Our competitors may also develop or market technologies or products that are more effective or commercially attractive than our current or future products or that would render our technologies and products obsolete. Further, additional competition could come from new entrants to the animal health care market. Moreover, we may not have the financial resources, technical expertise or marketing, sales or support capabilities to compete successfully. We believe that one of our largest competitors, IDEXX, currently in effect prohibits its distributors from selling competitive products, including our diagnostic instruments and heartworm diagnostic tests. Another of our competitors, Abaxis, recently launched a veterinary diagnostic laboratory offering which may serve to intensify competition and lower our margins.

If we fail to compete successfully, our ability to achieve sustained profitability will be limited and sustained profitability, or profitability at all, may not be possible.

If the third parties to whom we granted substantial marketing rights for certain of our existing products or future products under development are not successful in marketing those products, then our sales and financial position may suffer.

Our agreements with our corporate marketing partners generally contain no or small minimum purchase requirements in order for them to maintain their exclusive marketing rights. We are party to an agreement with SPAH, a unit of Merck, which grants SPAH exclusive distribution and marketing rights in the U.S. veterinary market for our canine heartworm preventive product, TRI-HEART Plus Chewable Tablets. Novartis Agro K.K., Tokyo ("Novartis Japan") markets and distributes our SOLO STEP CH heartworm test in Japan under an exclusive arrangement. AgriLabs has the non-exclusive right to sell certain of our bovine vaccines in the United States, Africa and Mexico and currently generates the majority of our sales of those vaccines in those territories. One or more of these marketing partners may not devote sufficient resources to marketing our products and our sales and financial position could suffer significantly as a result. Revenue from Merck entities, including SPAH, represented 9% of our LTM revenue. If SPAH personnel fail to market, sell and support our heartworm preventive sufficiently, our sales could decline significantly. Furthermore, there may be nothing to prevent these partners from pursuing alternative technologies or products that may compete with our products in current or future agreements. For example, we believe a unit of Merck has obtained FDA approval for a canine heartworm preventive product with additional claims compared with our TRI-HEART Plus Chewable Tablets which we believe is not currently being marketed actively. Should SPAH or a unit of Merck decide to emphasize sales and marketing efforts of this product rather than our TRI-HEART Plus Chewable Tablets or cancel our agreement regarding canine heartworm preventive distribution and marketing, our sales could decline significantly. In the future, third-party marketing assistance may not be available on reasonable terms, if at all. If any of these events occur, we may not be able to maintain our current market share or commercialize our products and our sales will decline accordingly.

-20-

We rely substantially on third-party suppliers. The loss of products or delays in product availability from one or more third-party suppliers could substantially harm our business.

To be successful, we must contract for the supply of, or manufacture ourselves, current and future products of appropriate quantity, quality and cost. Such products must be available on a timely basis and be in compliance with any regulatory requirements. Failure to do so could substantially harm our business.

We rely on third-party suppliers to manufacture those products we do not manufacture ourselves. Proprietary products provided by these suppliers represent a majority of our revenue. We currently rely on these suppliers for our veterinary instruments and consumable supplies for these instruments, for key components of our point-of-care diagnostic and other tests as well as for the manufacture of other products.

The loss of access to products from one or more suppliers could have a significant, negative impact on our business. Major suppliers who sell us proprietary products which are responsible for more than 5% of our LTM revenue are Boule Medical AB, FUJIFILM Corporation and Quidel Corporation ("Quidel"). None of these suppliers sold us proprietary products which were responsible for more than 25% of our LTM revenue, although the proprietary products of one of these suppliers was responsible for more than 20% of our revenue and another was responsible for more than 10% of our LTM revenue. We often purchase products from our suppliers under agreements that are of limited duration or potentially can be terminated on an annual basis. In the case of our veterinary diagnostic instruments other than for our lactate instrument, we are typically entitled to non-exclusive access to consumable supplies for a defined period upon expiration of exclusive rights, which could subject us to competitive pressures in the period of non-exclusive access. Although we believe we will be able to maintain supply of our major product offerings in the near future, there can be no assurance that our suppliers will meet their obligations under any agreements we may have in place with them or that we will be able to compel them to do so. Risks of relying on suppliers include:

Inability to meet minimum obligations. Current agreements, or agreements we may negotiate in the future, may commit us to certain minimum purchase or other spending obligations. It is possible we will not be able to create the market demand to meet such obligations, which could create a drain on our financial resources and liquidity. Some such agreements may require minimum purchases and/or sales to maintain product rights and we may be significantly harmed if we are unable to meet such requirements and lose product rights.

Changes in economics. An underlying change in the economics with a supplier, such as a large price increase or new requirement of large minimum purchase amounts, could have a significant, adverse effect on our business, particularly if we are unable to identify and implement an alternative source of supply in a timely manner.

The loss of product rights upon expiration or termination of an existing agreement. Unless we are able to find an alternate supply of a similar product, we would not be able to continue to offer our customers the same breadth of products and our sales and operating results would likely suffer. In the case of an instrument supplier, we could also potentially suffer the loss of sales of consumable supplies, which would be significant in cases where we have built a significant installed base, further harming our sales prospects and opportunities. Even if we were able to find an alternate supply for a product to which we lost rights, we would likely face increased competition from the product whose rights we lost being marketed by a third party or the former supplier and it may take us additional time and expense to gain the necessary approvals and launch an alternative product.

-21-

Loss of exclusivity. In the case of our veterinary diagnostic instruments, if we are entitled to non-exclusive access to consumable supplies for a defined period upon expiration of exclusive rights, we may face increased competition from a third party with similar non-exclusive access or our former supplier, which could cause us to lose customers and/or significantly decrease our margins and could significantly affect our financial results. For example, a third party has gained access to chemistry instrument test strips and supplies for our previous chemistry instrument which are provided to us by Arkray Global Business, Inc., has increased competition for these products with our customers and such competition may cause us to lose customers and/or significantly decrease our margins in the future. In addition, current agreements, or agreements we may negotiate in the future, with suppliers may require us to meet minimum annual sales levels to maintain our position as the exclusive distributor of these products. We may not meet these minimum sales levels and maintain exclusivity over the distribution and sale of these products. If we are not the exclusive distributor of these products, competition may increase significantly, reducing our revenues and/or decreasing our margins.

High switching costs. In our diagnostic instrument products we could face significant competition and lose all or some of the consumable revenues from the installed base of those instruments if we were to switch to a competitive instrument. If we need to change to other commercial manufacturing contractors for certain of our regulated products, additional regulatory licenses or approvals generally must be obtained for these contractors prior to our use. This would require new testing and compliance inspections prior to sale thus resulting in potential delays. Any new manufacturer would have to be educated in, or develop, substantially equivalent processes necessary for the production of our products. We likely would have to train our sales force, distribution network employees and customer support organization on the new product and spend significant funds marketing the new product to our customer base.

The involuntary or voluntary discontinuation of a product line. Unless we are able to find an alternate supply of a similar product in this or similar circumstances with any product, we would not be able to continue to offer our customers the same breadth of products and our sales would likely suffer. Even if we are able to identify an alternate supply, it may take us additional time and expense to gain the necessary approvals and launch an alternative product, especially if the product is discontinued unexpectedly.

·	Inconsistent or inadequate quality control. We may not be able to control or adequately monitor the quality of products we receive from our suppliers. Poor quality items could damage our reputation with our customers.

Limited capacity or ability to scale capacity. If market demand for our products increases suddenly, our current suppliers might not be able to fulfill our commercial needs, which would require us to seek new manufacturing arrangements and may result in substantial delays in meeting market demand. If we consistently generate more demand for a product than a given supplier is capable of handling, it could lead to large backorders and potentially lost sales to competitive products that are readily available. This could require us to seek or fund new sources of supply, which may be difficult to find or under terms that are less advantageous if available.

Regulatory risk. Our manufacturing facility and those of some of our third-party suppliers are subject to ongoing periodic unannounced inspection by regulatory authorities, including the FDA, USDA and other federal, state and foreign agencies for compliance with strictly enforced Good Manufacturing Practices, regulations and similar foreign standards. We do not have control over our suppliers' compliance with these regulations and standards. Regulatory violations could potentially lead to interruptions in supply that could cause us to lose sales to readily available competitive products.

·	Developmental delays. We may experience delays in the scale-up quantities needed for product development that could delay regulatory submissions and commercialization of our products in development, causing us to miss key opportunities.

·	Limited intellectual property rights. We typically do not have intellectual property rights, or may have to share intellectual property rights, to the products supplied by third parties and any improvements to the manufacturing processes or new manufacturing processes for these products.

-22-

Potential problems with suppliers such as those discussed above could substantially decrease sales, lead to higher costs and/or damage our reputation with our customers due to factors such as poor quality goods or delays in order fulfillment, resulting in our being unable to sell our products effectively and substantially harm our business.

Our future revenues depend on successful product development, commercialization and/or market acceptance, any of which can be slower than we expect or may not occur.

The product development and regulatory approval process for many of our potential products is extensive and may take substantially longer than we anticipate. Research projects may fail. New products that we may be developing for the veterinary marketplace may not perform consistent with our expectations. Because we have limited resources to devote to product development and commercialization, any delay in the development of one product or reallocation of resources to product development efforts that prove unsuccessful may delay or jeopardize the development of other product candidates. If we fail to successfully develop new products and bring them to market in a timely manner, our ability to generate additional revenue will decrease.

Even if we are successful in the development of a product or obtain rights to a product from a third-party supplier, we may experience delays or shortfalls in commercialization and/or market acceptance of the product. For example, veterinarians may be slow to adopt a product or there may be delays in producing large volumes of a product. The former is particularly likely where there is no comparable product available or historical use of such a product. The ultimate adoption of a new product by veterinarians, the rate of such adoption and the extent veterinarians choose to integrate such a product into their practice are all important factors in the economic success of one of our new products and are factors that we do not control to a large extent. If our products do not achieve a significant level of market acceptance, demand for our products will not develop as expected and our revenues will be lower than we anticipate. For example, our VitalPath Blood Gas and Electrolyte Analyzer generated less revenue than we anticipated following its launch in May 2010 as placements of this product with customers have not occurred as we expected.

We may face costly legal disputes, including related to our intellectual property or technology or that of our suppliers or collaborators.

We may face legal disputes related to our business. Even if meritless, these disputes may require significant expenditures on our part and could entail a significant distraction to members of our management team or other key employees. We may have to use legal means to collect payment for goods shipped to third parties. For example, we are currently involved in arbitration with a former distributor to whom we gave notice of contract termination in January 2010 regarding matters including amounts past due, for which we have recorded no specific reserves and counterclaims made by the former distributor. A legal dispute leading to an unfavorable ruling or settlement could have significant material adverse consequences on our business.

We may become subject to patent infringement claims and litigation in the United States or other countries or interference proceedings conducted in the United States Patent and Trademark Office, or USPTO, to determine the priority of inventions. The defense and prosecution of intellectual property suits, USPTO interference proceedings and related legal and administrative proceedings are likely to be costly, time-consuming and distracting. As is typical in our industry, from time to time we and our collaborators and suppliers have received, and may in the future receive, notices from third parties claiming infringement and invitations to take licenses under third-party patents. Any legal action against us or our collaborators or suppliers may require us or our collaborators or suppliers to obtain one or more licenses in order to market or manufacture affected products or services. However, we or our collaborators or suppliers may not be able to obtain licenses for technology patented by others on commercially reasonable terms, or at all, may not be able to develop alternative approaches if unable to obtain licenses or current and future licenses may not be adequate, any of which could substantially harm our business.

-23-

We may also need to pursue litigation to enforce any patents issued to us or our collaborative partners, to protect trade secrets or know-how owned by us or our collaborative partners, or to determine the enforceability, scope and validity of the proprietary rights of others. Any litigation or interference proceeding will likely result in substantial expense to us and significant diversion of the efforts of our technical and management personnel. Any adverse determination in litigation or interference proceedings could subject us to significant liabilities to third parties. Further, as a result of litigation or other proceedings, we may be required to seek licenses from third parties which may not be available on commercially reasonable terms, if at all.

We often depend on third parties for products we intend to introduce in the future. If our current relationships and collaborations are not successful, we may not be able to introduce the products we intend to in the future.

We are often dependent on third parties and collaborative partners to successfully and timely perform research and development activities to successfully develop new products. For example, we jointly developed point-of-care diagnostic products with Quidel. In other cases, we have discussed Heska marketing in the veterinary market an instrument being developed by a third party for use in the human health care market. In the future, one or more of these third parties or collaborative partners may not complete research and development activities in a timely fashion, or at all. Even if these third parties are successful in their research and development activities, we may not be able to come to an economic agreement with them. If these third parties or collaborative partners fail to complete research and development activities, fail to complete them in a timely fashion, or if we are unable to negotiate economic agreements with such third parties or collaborative partners, our ability to introduce new products will be impacted negatively and our revenues may decline.

We may not be able to continue to achieve sustained profitability or increase profitability on a quarterly or annual basis.

Prior to 2005, we incurred net losses on an annual basis since our inception in 1988 and, as of March 31, 2012, we had an accumulated deficit of $169.6 million. We have achieved only two quarters with income before income taxes greater than $1.5 million. Accordingly, relatively small differences in our performance metrics may cause us to generate an operating or net loss in future periods. Our ability to continue to be profitable in future periods will depend, in part, on our ability to increase sales in our CCA segment, including maintaining and growing our installed base of instruments and related consumables, to maintain or increase gross margins and to limit the increase in our operating expenses to a reasonable level as well as avoid or effectively manage any unanticipated issues. We may not be able to generate, sustain or increase profitability on a quarterly or annual basis. If we cannot achieve or sustain profitability for an extended period, we may not be able to fund our expected cash needs, including the repayment of debt as it comes due, or continue our operations.

Obtaining and maintaining regulatory approvals in order to market our products may be costly and delay the marketing and sales of our products. Failure to meet all regulatory requirements could cause significant losses from affected inventory and the loss of market share.

Many of the products we develop, market or manufacture may subject us to extensive regulation by one or more of the USDA, the FDA, the EPA and foreign and other regulatory authorities. These regulations govern, among other things, the development, testing, manufacturing, labeling, storage, pre-market approval, advertising, promotion and sale of some of our products. Satisfaction of these requirements can take several years and time needed to satisfy them may vary substantially, based on the type, complexity and novelty of the product. The decision by a regulatory authority to regulate a currently non-regulated product or product area could significantly impact our revenue and have a corresponding adverse impact on our financial performance and position while we attempt to comply with the new regulation, if such compliance is possible at all.

-24-

The effect of government regulation may be to delay or to prevent marketing of our products for a considerable period of time and to impose costly procedures upon our activities. We have experienced in the past, and may experience in the future, difficulties that could delay or prevent us from obtaining the regulatory approval or license necessary to introduce or market our products. Such delays in approval may cause us to forego a significant portion of a new product's sales in its first year due to seasonality and advanced booking periods associated with certain products. Regulatory approval of our products may also impose limitations on the indicated or intended uses for which our products may be marketed. Difficulties in making established products to all regulatory specifications may lead to significant losses related to affected inventory as well as market share. For instance, in 2010 we discovered we had produced a significant level of cattle vaccine product in our OVP segment which conformed to regulatory specifications for safety, potency and efficacy but not purity. We did not ship any related cattle vaccine product in the three months ended June 30, 2010 as we investigated and worked to resolve the situation. There can be no assurance that our efforts at remediation to ensure this or similar problems will not recur in the future will be successful or that the USDA will not suspend our ability to produce these, similar or other products for an extended time at some point in the future.

Among the conditions for certain regulatory approvals is the requirement that our facilities and/or the facilities of our third-party manufacturers conform to current Good Manufacturing Practices and other requirements. If any regulatory authority determines that our manufacturing facilities or those of our third-party manufacturers do not conform to appropriate manufacturing requirements, we or the manufacturers of our products may be subject to sanctions, including, but not limited to, warning letters, manufacturing suspensions, product recalls or seizures, injunctions, refusal to permit products to be imported into or exported out of the United States, refusals of regulatory authorities to grant approval or to allow us to enter into government supply contracts, withdrawals of previously approved marketing applications, civil fines and criminal prosecutions. In addition, certain of our agreements may require us to pay penalties if we are unable to supply products, including for failure to maintain regulatory approvals. Any of these events, alone or in unison, could damage our business.

Many of our expenses are fixed and if factors beyond our control cause our revenue to fluctuate, this fluctuation could cause greater than expected losses, cash flow and liquidity shortfalls.

We believe that our future operating results will fluctuate on a quarterly basis due to a variety of factors which are generally beyond our control, including:

·	supply of products from third-party suppliers or termination, cancelation or expiration of such relationships;

·	competition and pricing pressures from competitive products;

·	the introduction of new products or services by our competitors or by us;

·	large customers failing to purchase at historical levels;

·	fundamental shifts in market demand;

·	manufacturing delays;

·	shipment problems;

·	information technology problems, which may prevent us from conducting our business effectively, or at all, and may also raise our costs;

·	regulatory and other delays in product development;

·	product recalls or other issues which may raise our costs;

·	changes in our reputation and/or market acceptance of our current or new products; and

·	changes in the mix of products sold.

We have high operating expenses, including those related to personnel. Many of these expenses are fixed in the short term and may increase over the course of the coming year. If any of the factors listed above cause our revenues to decline, our operating results could be substantially harmed.

-25-

Our stock price has historically experienced high volatility, and could do so in the future, including experiencing a material price decline resulting from a large sale in a short period of time. In addition, our Public Common Stock has certain transfer restrictions which could reduce trading liquidity from what it otherwise would have been and have other undesired effects. Our recently completed 1-for-10 reverse stock split could also reduce liquidity in our stock.

According to the latest available filings with the SEC, we have one shareholder who holds approximately 11% of our shares outstanding and another who holds approximately 8% of our shares outstanding. Should either of these shareholders or another relatively large shareholder decide to sell a large number of shares in a short period of time, it could lead to an excess supply of our shares available for sale and correspondingly result in a significant decline in our stock price. For example, we had a shareholder who held over 16% of our shares outstanding as of September 30, 2011 sell all of its holdings in our stock on or before December 7, 2011 – and we believe this contributed to a corresponding decline in our stock price during this period.

The securities markets have experienced significant price and volume fluctuations and the market prices of securities of many microcap and smallcap companies have in the past been, and can in the future be expected to be, especially volatile. During the twelve months ended March 31, 2012, our closing stock price has ranged from a low of $6.47 to a high of $11.38. Fluctuations in the trading price or liquidity of our Public Common Stock may adversely affect our ability to raise capital through future equity financings. Factors that may have a significant impact on the market price and marketability of our Public Common Stock include:

·	stock sales by large stockholders or by insiders;

·	changes in the outlook for our business, including any changes in our earnings guidance;

·	our quarterly operating results, including as compared to our revenue, earnings or other guidance and in comparison to historical results;

·	termination, cancellation or expiration of our third-party supplier relationships;

·	announcements of technological innovations or new products by our competitors or by us;

·	litigation;

·	regulatory developments, including delays in product introductions;

·	developments or disputes concerning patents or proprietary rights;

·	availability of our revolving line of credit and compliance with debt covenants;

·	releases of reports by securities analysts;

·	economic and other external factors; and

·	general market conditions.

In the past, following periods of volatility in the market price of a company's securities, securities class action litigation has often been instituted. If a securities class action suit is filed against us, it is likely we would incur substantial legal fees and our management's attention and resources would be diverted from operating our business in order to respond to the litigation.

On May 4, 2010, our shareholders approved an amendment (the "Amendment") to our Restated Certificate of Incorporation. The Amendment places restrictions on the transfer of our stock that could adversely affect our ability to use our domestic Federal Net Operating Loss carryforward ("NOL"). In particular, the Amendment prevents the transfer of shares without the approval of our Board of Directors if, as a consequence, an individual, entity or groups of individuals or entities would become a 5-percent holder under Section 382 of the Internal Revenue Code of 1986, as amended, and the related Treasury regulations, and also prevents any existing 5-percent holder from increasing his or her ownership position in the Company without the approval of our Board of Directors. This may cause certain individuals or entities who may have otherwise been willing and able to bid on our stock to not do so, reducing the class of potential acquirers and trading liquidity from what it otherwise might have been. The Amendment could also have an adverse impact on the value of our stock if certain buyers who would otherwise have purchased our stock, including buyers who may not be comfortable owning stock with transfer restrictions, do not purchase our stock as a result of the Amendment. In addition, because some corporate takeovers occur through the acquirer's purchase, in the public market or otherwise, of sufficient shares to give it control of a company, any provision that restricts the transfer of shares can have the effect of preventing a takeover. The Amendment could discourage or otherwise prevent accumulations of substantial blocks of shares in which our common stockholders might receive a substantial premium above market value and might tend to insulate management and the Board of Directors against the possibility of removal to a greater degree than had the Amendment not passed.

-26-

We completed a 1-for-10 reverse stock split effective December 30, 2010. The liquidity of our Public Common Stock could be adversely affected by the reduced number of shares resulting from the reverse stock split. Our reverse stock split may have left certain stockholders with one or more "odd lots", which are stock holdings in fewer than 100 shares of Public Common Stock. These odd lots may be more difficult to sell and may incur higher brokerage commissions when sold than shares of our Public Common Stock in multiples of 100, reducing liquidity. Furthermore, due to the increased price per share following our 1-for-10 reverse stock split, certain smaller investors may be unwilling or unable to purchase shares of our Public Common Stock, also reducing liquidity.

Changes to, differing interpretations of, or changing circumstances under which we apply financial accounting standards may affect our results of operations, cause us to change our business practices or have a negative impact on us if we fail to track such changes.

We prepare our financial statements in conformance with United States generally accepted accounting principles, or GAAP. These accounting principles are established by and are subject to interpretation by the SEC, the Financial Accounting Standards Board ("FASB") and others who interpret and create accounting policies. A change in those policies can have a significant effect on our reported results and may affect our reporting of transactions completed before a change is made effective. Such changes may adversely affect our reported financial results, the way we conduct our business or have a negative impact on us if we fail to track such changes. For example, we have found FASB's recent decision to codify the accounting standards has made it more difficult to research complex accounting matters, increasing the risk we will fail to account consistent with FASB rules in the future. Similarly, changes in the underlying circumstances which we apply given accounting standards and principles may affect our results of operations and have a negative impact on us. For example, in the twelve months ended March 31, 2012, we recognized approximately $1 million in revenue related to large upfront payments received over five years ago from three third parties for certain product rights. In all three cases, we have deferred the revenue with a related deferred revenue liability on our balance sheet and recognized the revenue over the estimated life of the related agreements, products, patents or technology. If we are to conclude any or all of the estimated lives of the related agreements, products, patents or technology are to be extended, it could lead to a significant reduction in related revenue recognized in corresponding future periods.

Our Public Common Stock is listed on the Nasdaq Capital Market and we may not be able to maintain that listing, which may make it more difficult for you to sell your shares.

Our Public Common Stock is listed on the Nasdaq Capital Market. The Nasdaq has several quantitative and qualitative requirements companies must comply with to maintain this listing, including a $1.00 minimum bid price. We completed a 1-for-10 reverse stock split effective December 30, 2010 in order to resolve an ongoing minimum bid price deficiency. While we believe we are currently in compliance with all Nasdaq requirements, there can be no assurance we will continue to meet Nasdaq listing requirements including the minimum bid price, that Nasdaq will interpret these requirements in the same manner we do if we believe we meet the requirements, or that Nasdaq will not change such requirements or add new requirements to include requirements we do not meet in the future. If we are delisted from the Nasdaq Capital Market, our Public Common Stock may be considered a penny stock under the regulations of the SEC and would therefore be subject to rules that impose additional sales practice requirements on broker-dealers who sell our securities. The additional burdens imposed upon broker-dealers may discourage broker-dealers from effecting transactions in our Public Common Stock, which could severely limit market liquidity of the Public Common Stock and any stockholder's ability to sell our securities in the secondary market. This lack of liquidity would also likely make it more difficult for us to raise capital in the future.

-27-

We depend on key personnel for our future success. If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve our goals.

Our future success is substantially dependent on the efforts of our senior management and other key personnel. The loss of the services of members of our senior management or other key personnel may significantly delay or prevent the achievement of our business objectives. Although we have an employment agreement with many of these individuals, all are at-will employees, which means that either the employee or Heska may terminate employment at any time without prior notice. If we lose the services of, or fail to recruit, key personnel, the growth of our business could be substantially impaired. We do not maintain key person life insurance for any of our senior management or key personnel.

We have historically not consistently generated positive cash flow from operations, may need additional capital and any required capital may not be available on reasonable terms or at all.

If our actual performance deviates from our operating plan, we may be required to raise additional capital in the future. If necessary, we expect to raise these additional funds by borrowing under our revolving line of credit, the sale of equity securities or the issuance of new term debt secured by the same assets as the term loans which we fully repaid in 2010. There is no guarantee that additional capital will be available from these sources on reasonable terms, if at all, and certain of these sources may require approval by existing lenders. Funds we expect to be available under our existing revolving line of credit may not be available and other lenders could refuse to provide us with additional debt financing. The public markets may be unreceptive to equity financings and we may not be able to obtain additional private equity or debt financing. Any equity financing would likely be dilutive to stockholders and additional debt financing, if available, may include restrictive covenants and increased interest rates that would limit our currently planned operations and strategies. We believe the credit markets are particularly restrictive and difficult to obtain funding in versus recent history. Furthermore, even if additional capital is available, it may not be of the magnitude required to meet our needs under these or other scenarios. If additional funds are required and are not available, it would likely have a material adverse effect on our business, financial condition and our ability to continue as a going concern.

Interpretation of existing legislation, regulations and rules or implementation of future legislation, regulations and rules could cause our costs to increase or could harm us in other ways.

The Sarbanes-Oxley Act of 2002 ("Sarbanes-Oxley") has increased our required administrative actions and expenses as a public company since its enactment. The general and administrative costs of complying with Sarbanes-Oxley will depend on how it is interpreted over time. Of particular concern are the level of standards for internal control evaluation and reporting adopted under Section 404 of Sarbanes-Oxley. If our regulators and/or auditors adopt or interpret more stringent standards than we anticipate, we and/or our auditors may be unable to conclude that our internal controls over financial reporting are designed and operating effectively, which could adversely affect investor confidence in our financial statements. Even if we and our auditors are able to conclude that our internal controls over financial reporting are designed and operating effectively in such a circumstance, our general and administrative costs are likely to increase. Similarly, we are required to comply with the SEC's mandate to provide interactive data using the eXtensible Business Reporting Language as an exhibit to certain SEC filings in 2012. Compliance with this mandate has required a significant time investment, which may have and may in the future preclude some of our employees from spending time on more productive matters. In addition, actions by other entities, such as enhanced rules to maintain our listing on the Nasdaq Capital Market, could also increase our general and administrative costs or have other adverse effects on us, as could further legislative, regulatory or rule-making action or more stringent interpretations of existing legislation, regulations and rules.

-28-

If we are unable to maintain various financial and other covenants required by our credit facility agreement we will be unable to borrow any funds under the agreement and fund our operations.

Under our credit and security agreement with Wells Fargo, we are required to comply with various financial and non-financial covenants in order to borrow under the agreement. The availability of borrowings under this agreement may be important to continue to fund our operations. Among the financial covenants is a requirement to maintain minimum liquidity (cash plus excess borrowing base) of $1.5 million. Additional requirements include covenants for minimum capital monthly and minimum net income quarterly. Although we believe we will be able to maintain compliance with all these covenants and any covenants we may negotiate in the future, there can be no assurance thereof. We have not always been able to maintain compliance with all covenants under our credit and security agreement with Wells Fargo in the past. Although Wells Fargo granted us a waiver of non-compliance in each case, there can be no assurance we will be able to obtain similar waivers or other modifications if needed in the future on economic terms, if at all. Failure to comply with any of the covenants, representations or warranties, or failure to modify them to allow future compliance, could result in our being in default and could cause all outstanding borrowings under our credit and security agreement to become immediately due and payable, or impact our ability to borrow under the agreement. In addition, Wells Fargo has discretion in setting the advance rates which we may borrow against eligible assets. We may need to rely on available borrowings under the credit and security agreement to fund our operations in the future. If we are unable to borrow funds under this agreement, we will need to raise additional capital from other sources to continue our operations, which capital may not be available on acceptable terms, or at all.

We may face product returns and product liability litigation in excess of or not covered by our insurance coverage or indemnities and/or warranties from our suppliers. If we become subject to product liability claims resulting from defects in our products, we may fail to achieve market acceptance of our products and our sales could substantially decline.

The testing, manufacturing and marketing of our current products as well as those currently under development entail an inherent risk of product liability claims and associated adverse publicity. Following the introduction of a product, adverse side effects may be discovered. Adverse publicity regarding such effects could affect sales of our other products for an indeterminate time period. To date, we have not experienced any material product liability claims, but any claim arising in the future could substantially harm our business. Potential product liability claims may exceed the amount of our insurance coverage or may be excluded from coverage under the terms of the policy. We may not be able to continue to obtain adequate insurance at a reasonable cost, if at all. In the event that we are held liable for a claim against which we are not indemnified or for damages exceeding the $10 million limit of our insurance coverage or which results in significant adverse publicity against us, we may lose revenue, be required to make substantial payments which could exceed our financial capacity and/or lose or fail to achieve market acceptance.

We may be held liable for the release of hazardous materials, which could result in extensive clean up costs or otherwise harm our business.

Certain of our products and development programs produced at our Des Moines, Iowa facility involve the controlled use of hazardous and biohazardous materials, including chemicals and infectious disease agents. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by applicable local, state and federal regulations, we cannot eliminate the risk of accidental contamination or injury from these materials. In the event of such an accident, we could be held liable for any fines, penalties, remediation costs or other damages that result. Our liability for the release of hazardous materials could exceed our resources, which could lead to a shutdown of our operations, significant remediation costs and potential legal liability. In addition, we may incur substantial costs to comply with environmental regulations if we choose to expand our manufacturing capacity.
