Microbiologics, Inc.

January 31, 2008

St. Cloud, Minnesota - Granite Equity has invested in one of Central Minnesota’s leading bioscience companies, MicroBioLogics, Inc.  MicroBioLogics has been and will continue to be led by its Chief Executive Officer, Bob Coborn.

In this next phase of the Company’s growth, Bob White, former Chief Executive Officer of Wolters Kluwer Financial Services, will join the Company’s Board of Directors as its Chair.  White, who studied microbiology at St. Cloud State during college, researched tuberculosis at the Presidio during his stint in the Army.  White is also currently the Board Chair of the St. Cloud Hospital.  White’s unique background, with strong science and business leadership experience, makes him well suited to assist MicroBioLogics with its growth plans.

Bob White, in reflecting on the company noted, “With increased movement of people, goods, and services around the world and with the advent of drug resistant strains of bacteria, the world has many risk factors which need to be managed and tested.  MicroBioLogics provides the raw materials for the conduct of these tests, making the world a safer place.”

“MicroBioLogics is a true global leader in our market niche, making us an excellent fit with Granite Equity’s mission of working with leading private companies in our community.  Their commitment to the community, our employees, and stakeholders made them the best choice as our future growth partner,” said Coborn.

MicroBioLogics, founded in the early 1970’s as a lab testing business, has grown into one of the world’s leading producers of lyophilized (freeze-dried) microorganisms used for quality control testing in worldwide markets for clinical, food safety, water quality, pharmaceutical, and consumer products.  The company manufactures and distributes microbes into more than 100 countries worldwide, with more than 10,000 distinct end users.

The new partnership will allow the company to buy-back a number of shares from shareholders who invested in the company during its early stage and developmental years.  Granite will take the place of those early investors in the ownership group with the current Board and management keeping a large stake in the company.

In addition to White, Granite will bring two more new members to the Board of Directors including Michael Faber, President of Viking Coca Cola and a Granite Equity investor; and Pat Edeburn, who joined Granite Equity in 2002 after nearly ten years of market and business development with Medtronic.  These new Board members will join local businessmen Galen Kabe and Bob Coborn, who are both long-standing members of the Board.
