Item 1.01  Entry into a Material Definitive Agreement

On February 29, 2012, Mesa Laboratories, Inc. (the “Company’), entered into a three year agreement for a $20,000,000 revolving line of credit and up to $1,000,000 of letters of credit with JPMorgan Chase Bank, N.A. (“Chase Bank”).  Funds from the Credit Facility may be used for general working capital and corporate needs, retiring existing debt, or to support acquisitions and capital expenditures.

Under the Credit Facility, indebtedness bears interest at either: (1) LIBOR plus an applicable margin, ranging from 1.25% to 2.00%,; or (2) the bank’s commercial bank floating rate (“CBFR”), which is the greater of the bank’s prime rate or one month LIBOR + 2.50%, adjusted down, from 1.25% to 0.50%.  Management elects the interest rate with each borrowing under the line of credit.  There is also an unused capacity fee of 0.15% to 0.30%.  The adjustments and unused capacity fee depend on the ratio of funded debt to the Company’s trailing four quarters of EBITDA, as defined, with four tiers ranging from a ratio of less than one to greater than two.  Letter of credit fees are based on the applicable LIBOR rate.

The Credit Facility is secured by all assets of the Company.  The Credit Facility allows us to maintain a ratio of funded debt to the Company’s trailing four quarters of EBITDA, as defined, to a maximum of 2.5 to 1.0, and a minimum fixed charge coverage ratio of 1.5 to 1.0.  Events of default under the Credit Facility include:

·                  failure to pay any principal or reimbursement obligation;

·                  failure to pay any interest or any other fee;

·                  failure to observe or perform any covenant;

·                  certain events of bankruptcy, insolvency or reorganization.

An event of default may result in (a) termination of the revolving commitment, and (b) loans then outstanding becoming due and payable.

Item 1.02  Termination of a Material Definitive Agreement

In connection with entering into the Credit Facility, on February 29, 2012, the Company repaid in full all obligations and liabilities owing under, and terminated, its $7,000,000 debt agreement with Colorado State Bank and Trust, N.A.  This payment included $1,500,000 in principal, plus interest.
