|   | The accompanying unaudited consolidated financial statements of Atrion Corporation and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, these statements include all adjustments necessary to present a fair statement of our consolidated results of operations, financial position and cash flows. Operating results for any interim period are not necessarily indicative of the results that may be expected for the full year. Preparation of the Company’s financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts in the financial statements and notes. Actual results could differ from those estimates. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s consolidated financial statements and notes included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2010 ("2010 Form 10-K").

|   | Incremental shares from stock options, unvested restricted stock, restricted stock units and deferred stock units were included in the calculation of weighted average diluted shares outstanding using the treasury stock method. Dilutive securities representing 4 and 26 shares of common stock for the quarters ended March 31, 2010 and 2011, respectively, were excluded from the computation of weighted average diluted shares outstanding because their effect would have been anti-dilutive.                                                                               |

|   | As of March 31, 2011, we held certain investments that are required to be measured for disclosure purposes at fair value on a recurring basis. These investments are considered Level 2 investments. We consider as current assets those investments which will mature in the next 12 months. The remaining investments are considered non-current assets.

|   | Our effective tax rate for the first quarter of 2011 was 34.2 percent, compared with 34.8 percent for the first quarter of 2010. The decrease in the effective tax rate for the 2011 period is primarily a result of the reinstatement in December 2010 of the federal tax credit for research and development, or R&D, expenditures. |

|   | On April 27, 2011, Alabama suffered a natural disaster of historic proportions when a large number of tornadoes hit the state. We operate a facility in the affected region. Our facility was not damaged, but the entire region was without power for several days. As a result, we have incurred and will continue to incur costs associated with disaster recovery, including assistance to our employees and community, the loss of several days of molding production, the running of our automated assembly on diesel generators, and the need to operate overtime during the second quarter to replenish safety stock of finished goods used to ensure continuous deliveries to our customers. Power has now been restored, and the facility is back to normal operations. We do not expect these additional costs or the interruption of our production to have a material adverse effect on our business, financial condition or results of operations. |
