category by Ernst and Young, a national audited program. Under MacDonald's
leadership, Medifast was ranked 28 of 200 on Forbes' list of the 200 Best Small
Companies in America, which was published in an October 2006 issue.

    The important role of Executive Chairman will allow for concentration on
strategic and financial advisory issues with the company while turning over the
day-to-day operation to Mr. McDevitt and his staff, including general management
and investor relations.

    "Michael McDevitt has earned the position of CEO. Over the last few years he
has been a key strategic partner in developing our growth strategy that has
assisted the company to reach almost double its revenues and profits this year.
As the largest shareholder of Medifast, I am confident that he will add
significant value to the company moving forward. I appreciate the support given
to me by our executive team, associates, vendors and board of directors who have
represented shareholder interest well over the last 10 years. As Chairman of the
Board, I look forward to working with Michael and his staff in developing our
future growth plans," stated Bradley T. MacDonald.

    Mr. McDevitt joined the company in June of 2002 and his primary
responsibilities have included oversight of the Medifast business including
financial, operational and marketing functions associated with each arm of the
company's multiple sales distribution channels. He has played a key role in the
design of the overall strategy of the Medifast business for the last four years
serving the company in positions including Controller, VP of Finance and his
current position of President and CFO. Prior to Medifast, Mr. McDevitt was a
Senior Analyst for The Blackstone Group, a Private Equity Group in New York
City.

    "I am excited to take on this role for Medifast, Inc. as we embark on a
mission to improve the lives of millions of people by providing innovative
choices for lasting health. Our dynamic multi-channeled business model provides
us the opportunity for success on many levels in a customer-driven world. I am
proud to take on the lead role of a company that is not only dedicated to
quality management and commitment to enhancing shareholder equity, but also to
improving the health of millions of people in a time when obesity is such a
growing problem in our society. I am looking forward to working with my
executive team to take our company to the next level," stated Michael S.
