DEAR FELLOW SHAREHOLDER:
 
     As you know, a dissident group of shareholders led by Steel Partners II,
L.P. ("Steel"), a Delaware limited partnership, is soliciting your vote in an
effort to take control of your Company. Steel wants control of your Company, but
is not willing to pay shareholders a control premium, or any thing at all for
such control. After careful review, your Board of Directors unanimously
concluded that Steel's efforts, are not in the best interest of MICA and all its
shareholders. Your Board of Directors urges you NOT to sign or return any proxy
cards you receive from this group. INSTEAD, SUPPORT YOUR BOARD OF DIRECTORS BY
SIGNING, DATING AND MAILING PROMPTLY YOUR GREEN PROXY CARD.
 
                        CONSEQUENCES OF STEEL'S ELECTION
 
     Steel has stated that it is not currently aware of any agreement, the
termination of which would be adversely affected by the election of its slate.
DON'T BE MISLED! Under the terms of your Company's Convertible Subordinated
Debentures, MICA is obligated to offer to prepay $8.2 million in the event of a
"change in control", which is defined to include the acquisition by a person or
group of persons of the power to elect a majority of the Board. Should your
Company be required to prepay this debt, its ability to effect business
combinations and to pursue other attractive transactions would be severely
limited. A VOTE FOR STEEL COULD EFFECTIVELY FORCE MICA INTO DEFAULT UNDER THE
TERMS OF ITS DEBENTURE IF IT CANNOT MEET THE PREPAYMENT OBLIGATION. HOW CAN
STEEL BELIEVE THAT EITHER AN $8.2 MILLION PREPAYMENT OF DEBT OR SUCH AN EVENT OF
DEFAULT IS IN THE BEST INTERESTS OF ALL OF OUR SHAREHOLDERS?
 
                      DON'T BE FOOLED BY STEEL'S RHETORIC
 
     Steel is waging a campaign filled with inaccuracies, misleading statements
and innuendo. In an attempt to win your support, Steel wants you to believe they
are responsible for the increase in the price of your stock. The next thing they
will ask you to believe is that there is a tooth fairy.
 
       - DON'T BE FOOLED BY STEEL'S RHETORIC -- IT IS THE PERFORMANCE OF THE
         COMPANY UNDER YOUR COMPANY'S CURRENT BOARD OF DIRECTORS AND THE
         MARKET'S ASSESSMENT OF ITS FUTURE PROSPECTS UNDER THE LEADERSHIP OF
         THIS BOARD THAT IS RESPONSIBLE FOR THE STOCK'S STRONG PERFORMANCE. From
         the first full quarter on, since current management took charge in late
         1994, your company has been profitable and your stock price has
         increased 140%.
 
     Steel has implied that Bob Muehlberg, the company's CEO and the executive
responsible for leading your company's turnaround, was the company's Chief
Operating Officer throughout its less successful times.
 
       - NOT TRUE! Mr. Muehlberg was not named COO until November 14, 1994. That
         quarter the company reduced its losses -- excluding severance charges
         for the company's prior CEO -- to $55,000 and has been profitable every
         single quarter since. But you don't have to take our word that
         shareholders have been impressed and benefitted by Bob's performance,
         take a look at what Steel told its own investors about your company and
         its management in a letter dated July 21, 1995.
   3
 
     "Another jewel we believe we have found is Medical Imaging Centers of
     America, Inc. MIKA owns and operates fixed site medical diagnostic imaging
     centers which provide services such as MRI, CT, Ultrasound and X-Ray. We
     think this will be a rapidly consolidating industry and that MIKA can
     become a major player in this highly fragmented industry. Due to MIKA's
     large fixed asset base and high depreciation expense they have low reported
     earnings but a very strong cash flow. Management has recently been
     reshuffled and is now headed by Robert Muehlberg. Bob has been with MIKA
     for ten years and knows the business well..."
 
     Based upon these comments, we're surprised that Steel is now trying to
replace the Board and effectively the management of your Company.
 
                         LET'S SET THE RECORD STRAIGHT
 
     In its latest letter to MICA shareholders, Steel alleges: "One director,
Keith Burnett, is a principal in a private company which was paid more than
$1,200,000 in 1995 for their interest in four radiology centers owned by your
Company."
 
       - CONTRARY TO WHAT STEEL WANTS YOU TO BELIEVE, THE TRUTH IS that your
         Company did not pay Keith Burnett (except for his service as Director)
         or his radiology group any amount in 1995. The fact is that Keith
         Burnett's group received $1.2 million from various insurance companies
         (third parties) for professional services provided to patients and
         these facts were clearly disclosed in your Company's proxy statement on
         page 15.
 
     Steel has also told you that: "The Board recently amended their
Co-Director's Muehlberg's and Sunseri's employment agreements to add substantial
new severance payments if the shareholders vote the existing Board out of
office."
 
       - CONTRARY TO WHAT STEEL WANTS YOU TO BELIEVE, THE TRUTH IS that the
         amendments to the employment agreements did not add any new severance
         payments but broadened the existing "change in control" provisions to
         include a change in the majority of the board and these facts were
         clearly disclosed in your Company's proxy statement on page 11.
 
     Finally, Steel wants you to believe that: "your Board and management cut a
sweetheart deal with one of the Company's largest creditors."
 
       - NOTHING COULD BE FURTHER FROM THE TRUTH. The creditor referred to by
         Steel exercised warrants that were granted in 1993 for investment
         purposes. The transaction which Steel refers to as a sweetheart deal
         included an early prepayment of debt but it also enabled your Company
         to realize a 15% discount on existing debt bearing interest of 10%. THE
         PREPAYMENT OF DEBT WAS BOTH IN THE BEST INTEREST OF THE COMPANY AND ITS
         SHAREHOLDERS.
 
     In deciding how to vote, we urge you to consider Steel's tactics, including
its use of misleading statements, half-truths and innuendo -- then, in what we
believe are your own best interests, sign, date and mail your GREEN Proxy Card
supporting your Board of Directors.
 
                      TAKE A CLOSE LOOK AT STEEL'S RECORD
                          WITH OTHER PUBLIC COMPANIES
 
     We are disappointed, but not surprised, that Steel has resorted to such
tactics in this proxy contest. We think that Steel's record speaks for itself.
And remember, Steel wants control of your Company but is unwilling to provide
you with a premium price for such control. In addition to our
   4
 
current hostile proxy contest, you should know that the following companies have
been subjected to "raids" by Steel:
 

                                       
        Kinark Corp.                      Parallan Computer, Inc.
        Park Ohio Industries, Inc.        P&F Industries, Inc.
        SC Industries, Inc.               Regency Equities Corp.
        Esquire Radio & Electronics, Inc. Synercom Technology, Inc.
        Gateway Communications, Inc.      AutoInfo Inc.

 
     In 1995, Steel took equity positions in Regency Equity Corp. and AutoInfo
Inc. In each case, the company filed suit against Steel for filing false and
misleading Schedule 13D's that failed to disclose Steel's original intent to
take control of the Company. Also in 1995, Kinark Corporation engaged its legal
counsel to investigate Steel's trading in its stock expressing a concern that
Steel might be abusing its position as an insider to profit at the expense of
other shareholders. Ask yourself: based upon Steel's history, do you want Steel
to control your Company? WE THINK THE ANSWER IS A RESOUNDING NO.
 
                  STEEL'S INTERESTS ARE NOT THE SAME AS YOURS
 
     Steel would have you believe that its slate of directors interests are the
same as yours. Unlike your company's current Board, Steel has no fiduciary
responsibility to MICA's shareholders. Steel's interests include affiliated
transactions with its nominated slate of directors involving brokerage
commissions, legal fees, and management and advisory fees provided to Steel. ASK
YOURSELF: ARE STEEL'S INTEREST THE SAME AS YOURS?
 
                          DELIVERING SHAREHOLDER VALUE
 
     During the year just ended, your Company posted dramatic improvements in
fourth quarter and year end results, which included an increase in shareholders'
equity of more than $5.7 million. We believe that our improved performance is
solid proof that our strategic plan is working and delivering value for all MICA
shareholders and we share with you a common interest in seeing your Company
prosper for the benefit of all shareholders.
 
     It is unfortunate that this costly and disruptive contest has arisen at a
time when the efforts of your Board of Directors and management should be
devoted exclusively to managing our business and maximizing shareholder value.
Rest assured that we will vigorously oppose Steel and their attempt to take
control of MICA, which, in our view, would disrupt the implementation of our
strategy to increase shareholder value. To support your Board of Directors, you
are urged to sign, date and promptly mail your GREEN Proxy Card. Please act
today and remember, do not sign any card which the dissident group may send you.
 
     We will continue every effort to protect and maximize the value of your
investment. We are committed to keeping you informed. On behalf of your Board of
Directors, thank you for your continued support.
 
Sincerely,
[SIG]
Robert S. Muehlberg
CHAIRMAN OF THE BOARD AND
CHIEF EXECUTIVE OFFICER
