The information in this Item 7.01 of this Current Report, including Exhibit 99.1 hereto, is being furnished to the Securities and Exchange Commission (“SEC”) and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section. This information shall not be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Cautionary Note Regarding Forward-Looking Statements

Certain of the statements contained in this Current Report on Form 8-K are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. Such forward-looking statements may include, without limitation, statements about the proposed transaction with EyeSouth Partners, the expected timetable for completing the proposed transaction, the benefits of the proposed transaction, future opportunities for the Company and EyeSouth Partners and any other statements regarding the Company’s or EyeSouth Partners’ future operations, financial or operating results, anticipated business levels, future earnings, planned activities, anticipated growth, market opportunities, strategies, and other expectations for future periods. Words such as “aim,” “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “on track,” “opportunity,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “strive,” “sustain,” “synergy,” “target,” “will,” “would” and similar expressions are intended to identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Because forward-looking statements inherently involve risks and uncertainties, actual future results may differ materially from those expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to: the parties’ ability to meet expectations regarding the timing of the proposed transaction; the parties’ ability to consummate the proposed transaction; the regulatory approvals required for the proposed transaction not being obtained on the terms expected or on the anticipated schedule or at all; inherent uncertainties involved in the estimates and judgments used in the preparation of financial statements and the providing of estimates of financial measures, in accordance with GAAP and related standards, or on an adjusted basis; the Company’s or EyeSouth Partners’ failure to achieve expected or targeted future financial and operating performance and results; the possibility that the Company may be unable to achieve expected benefits, synergies and operating efficiencies in connection with the proposed transaction within the expected time frames or at all; business disruption being greater than expected following the proposed transaction; the recruiting and retention of key physicians and employees being more difficult following the proposed transaction; the effect of any changes in customer and supplier relationships and customer purchasing patterns; the impacts of competition; changes in the economic and financial conditions of the business of the Company or EyeSouth Partners; the Company’s de-leveraging plans and the ability of the Company to maintain its investment grade rating; and uncertainties and matters beyond the control of management and other factors described under “Risk Factors” in the Company’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other filings with the SEC. You can access the Company’s filings with the SEC through the SEC website at www.sec.gov or through the Company’s website, and the Company strongly encourages you to do so. Except as required by applicable law, the Company undertakes no obligation to update any statements herein for revisions or changes after the date of this communication.
