Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On February 10, 2012, Cerner Corporation, a Delaware corporation (the “Company”), entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) with a syndicate of lenders identified in the Credit Agreement. U.S. Bank National Association acts as Administrative Agent under the Credit Agreement.

The Credit Agreement is a $100 million five-year revolving credit facility and includes: (a) a revolving credit loan facility of up to $100 million at any time outstanding, with an accordion feature that permits an increase of up to $50 million on the terms set forth in the Credit Agreement; (b) a swingline loan credit facility of up to $3 million at any time outstanding (which is a sub-facility of the $100 million revolving credit loan facility); and (c) a letter of credit facility of up to $100 million at any time outstanding (which is a sub-facility of the $100 million revolving credit loan facility). The Credit Agreement renewed, extended and increased from $90 million to $100 million our unsecured line of credit under that certain Amended and Restated Credit Agreement dated as of November 30, 2006, as amended by that certain First Amendment to Amended and Restated Credit Agreement dated as of November 12, 2009. There were no amounts outstanding under the Credit Agreement, other than letters of credit, at the time the credit facility was renewed.

Generally, amounts outstanding under the Credit Agreement bear interest at interest rates based on either the LIBOR rate (selected by the Company for designated interest periods) or the alternative Base Rate (the highest of (1) the Prime Rate, (2) the Federal Funds Rate plus 1.5%, and (3) the Adjusted Daily LIBOR Rate in effect and reset each LIBOR Business Day plus 2.00%), plus, in each case, a margin based on our leverage ratio. We are required to pay certain fees in connection with the Credit Agreement. For example, we must pay commitment fees on a quarterly basis with respect to the unutilized portion of the commitments under the Credit Agreement. Additionally, we are required to pay certain fees to the Administrative Agent for administrative services.

The Credit Agreement contains customary representations and warranties, covenants, and events of default. Amounts outstanding under the Credit Agreement may be accelerated upon the occurrence of an event of default.

The Credit Agreement has been filed herewith to provide investors with the agreed upon terms of the transactions described in this current report on Form 8K. The Credit Agreement is not intended to be a source of factual, business or operational information about our company or our subsidiaries. The representations, warranties and covenants contained in the Credit Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the parties, including being qualified by disclosures for the purpose of allocating contractual risk between the parties instead of establishing matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, investors should not rely on the representations, warranties, and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties.

Capitalized terms used but not defined herein shall have the meanings set forth in the Credit Agreement. The above description is qualified in its entirety by reference to the Credit Agreement which is filed with this current report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

99.1 Amended and Restated Credit Agreement dated February 10, 2012 among Cerner Corporation, U.S. Bank National Association, Commerce Bank, Bank of America, N.A., UMB Bank, N.A. and RBS Citizens, N.A.
