Remarks
Evan Guillemin, a member and the principal financial officer of SEG Ventures, LLC ("SEG Ventures"), was appointed to the Board of Directors of Mesa Laboratories, Inc. (the "Issuer") on February 25, 2009. SEG Ventures is filing this Form 4 on the basis that, solely for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, it may be deemed a director of the Issuer by deputization due to Mr. Guillemin's directorship. SEG Ventures disclaims beneficial ownership of the shares of Common Stock of the Issuer directly beneficially owned by Mr. Guillemin.
