   WHEN DOES IT END, WHEN WILL MR. AUHLL AND HIS BOARD STOP IGNORING CIRCON'S
                                 SHAREHOLDERS?
 
                                                             September 22, 1997
 
Dear Fellow Circon Shareholders:
 
  We would like to bring to your attention information contained in Circon's
proxy material that we believe sums up exactly what we have been saying during
the last 13 months about Mr. Auhll and his Board of Directors--THAT HE AND THE
BOARD CANNOT BE TRUSTED AND THAT THEY ARE PUTTING THEIR INTERESTS BEFORE YOURS.
 
  This is what the Circon Board has to say:
 
  IF UNITED STATES SURGICAL CORPORATION'S NOMINEES FOR
  DIRECTORS ARE ELECTED AND, AS A RESULT, MR. AUHLL IS NOT
            ---                                        ---
  REELECTED AS A DIRECTOR, CIRCON'S BOARD MAY CONSIDER
  ALTERNATIVE STRATEGIES THAT PERMIT MR. AUHLL TO REMAIN ON
                                                  ------
  THE BOARD.
 
  WE INTERPRET THIS TO MEAN, "HEADS" HE WINS, AND "TAILS" YOU LOSE. THIS IS
                                     -------              --------
PREPOSTEROUS, UNDEMOCRATIC, AND CERTAINLY NOT IN THE BEST INTEREST OF CIRCON'S
SHAREHOLDERS.
 
  Stop Auhll and his Board from depriving you of an opportunity to maximize the
value of your Circon shares. Demand that they stop ignoring the wishes of
Circon's shareholders to sell the Company to the highest bidder.
 
  There are only 14 days left before the October 6th Circon Annual Meeting. We
urge you to vote on the enclosed United States Surgical BLUE Proxy Card FOR our
Director Nominees and FOR the Maximize Value Resolution.
 
  Thank you for your continued support.
 
                                  On behalf of the board,
 
                                  /s/ Leon C. Hirsch
                                  Leon C. Hirsch, Chairman
                                  United States Surgical Corporation
 
                                     (Over)

 
 
                                   IMPORTANT
 
    Your vote is important, no matter how many or how few Circon shares
  you own. U.S. Surgical urges you to mark, sign, date and return the
  enclosed BLUE proxy card to vote FOR the election of the U.S. Surgical
  nominees and FOR the approval of the Maximize Value Resolution.
 
    If your Circon shares are registered in your own name, please mark,
  sign and date the enclosed BLUE proxy card. Return the proxy card to
  U.S. Surgical, c/o Kissel-Blake Inc. in the enclosed envelope in time
  to be voted at the Annual Meeting. If any of your Circon shares are
  held in the name of a brokerage firm, bank, bank nominee or other
  institution on the record date, only it can vote such Circon shares
  and only upon receipt of your specific instructions. Accordingly,
  please contact the person responsible for your account and instruct
  that person to execute on your behalf the BLUE proxy card.
 
    Remember--even if you have already tendered your Circon shares in
  U.S. Surgical's Offer, you must vote your Circon shares on the
  enclosed BLUE proxy card to support U.S. Surgical's nominees and the
  Maximize Value Resolution.
 
    If you already voted a white proxy card but wish to support the U.S.
  Surgical nominees and Maximize Value Resolution, please sign, date and
  mail the enclosed BLUE proxy card in the postage paid envelope since
  only the latest dated proxy is valid.
 
    For additional information please review the Proxy Statement of U.S.
  Surgical dated August 11, 1997.
 
    If you have any questions or require assistance voting your Circon
  shares, please call our proxy solicitors:
