September 24, 2001; October 12, 2001 and May 31, 2002 (together, the "Employment
Agreement").

      Term of Employment. The Employment Period, as defined in Section 2 of the
      Amended Executive Employment Agreement, is extended to August 31, 2003.

If the foregoing is acceptable to you, please indicate your agreement by signing

                                   Very truly yours,

Stephen C. Farrell<PAGE>
                                                                   EXHIBIT 10.58

      This Agreement (the "Agreement") is entered into and is effective as of
the 4th day of August, 2002, by and between Steven J. Lee ("Executive"),
PolyMedica Corporation, a Massachusetts Corporation (the "Company") and the
Board of Directors of the Company (the "Board of Directors").

BACKGROUND

      The Company, through its Board of Directors, and the Executive have come
to the conclusion that the Company is at a stage in its development where it is
now appropriate for the Executive to retire and for the Company to identify
another person to lead the Company as it continues to grow. This important
business decision, however, is taking place at a time when the Company is the
subject of government investigations and civil litigation, as noted in Section
4.1 of this Agreement. It is of great importance to both the Board of Directors
and the Executive that the retirement of the Executive not be interpreted by
others as being due to a finding of impropriety as to the Executive. Such an
interpretation would be inaccurate. Nor is the Company determined to attempt to
resolve some or all of the proceedings in which it is currently involved by
offering to provide information to third parties concerning the Executive. The
existence of the proceedings was not the primary basis for the decision by the
Board to accept the Executive's resignation. The primary basis for their
decision was the mutual recognition by both the Executive and the Company that
the Executive decided to resign and the Company required a new CEO.

RECITALS

      WHEREAS Executive and the Company previously entered into an Executive
Retention Agreement dated as of September 1, 2000 and an Amended Executive
Employment Agreement dated April 1, 2001, as amended on June 8, 2001, September
25, 2001 and May 13, 2002 (collectively, all of the foregoing agreements shall
be referred to as the "Previous Agreements");

      WHEREAS Executive and the Company now desire for this Agreement to
immediately supersede all Previous Agreements; and

      WHEREAS Executive and the Company acknowledge that this Agreement is
desirable and would not otherwise be entered into unless the Agreement
supersedes the Previous Agreements;

      WHEREAS Executive and the Company desire for this Agreement to resolve
amicably and on mutually satisfactory terms any and all issues relating to the
Executive's resignation from employment with the Company;

      WHEREAS Executive desires to resign his position as Chief Executive
Officer on the date hereof and as Chairman and a member of the Board of
Directors on January 1, 2003 and the Company recognizes Executive's valuable
service to the Company;

      NOW THEREFORE, in consideration of the mutual promises and forbearances
set forth in this Agreement, and other good and valuable consideration which
Executive and the Company hereby acknowledge, Executive and the Company agree as
follows:

      -     In re: Polymedica Corp. Shareholder Derivative Litig., Civ. A. No.
            01-3446, Superior Court of Middlesex County, Commonwealth of

      -     The SEC inquiry and the investigations currently being conducted by
            the United States Attorney's for the Southern District of Florida
            and the Southern District of Illinois

      The Company further acknowledges that, pursuant to such Section 3, the

effect as to the Executive after the date hereof.

      5. NON-DISPARAGEMENT.

            5.1 The Company, the Senior Executives and Directors agree not to
take any action or make any statement which is false with respect to,
disparages, criticizes, or is derogatory with respect to, Executive regardless
of whether such statements would be actionable under statutory or common law
liability theories. The Company agrees that, upon Executive's request, or upon
any inquiry regarding Executive, the Company will provide a letter of
recommendation identical to the attached Exhibit C.

            5.2 The Executive understands and agrees that he shall not make any
false, disparaging or derogatory statements to any media outlet, industry group,
financial institution, investor, current or former employee, consultant, client
or customer of the Company or any other third party, regarding the Company or
any of its directors, officers, employees, attorneys, agents or representatives
or about the Company's business affairs or financial condition. The Executive
further agrees not to make any statement of any kind to any media outlet other
than what has been mutually agreed upon as a press release with the Company,
which is attached as Exhibit D hereto.

            5.3 The parties recognize that the Company may provide information
to a Governmental Entity (as defined below) or plaintiffs, as the case may be,
on a voluntary basis. Nothing in this agreement shall be construed to limit or
impede such voluntary cooperation or anyone acting on behalf of the Company from

specifically enforced by Executive or the Company, as applicable, it being
agreed that money damages are not an adequate remedy for breach of Sections 5.1,
5.3 or 5.4.

      6. COOPERATION.

            6.1 The Executive agrees to cooperate fully with the Company in the

whether before or by a state or federal court or by any local, state or federal
government agency. The Executive's full cooperation in connection with such

discovery or an administrative hearing and to act as a witness when requested by
the Company at reasonable times designated by the Company. Executive agrees to

matters set forth in Section 4 above, unless (a) Executive is or may be a
subject or target of said grand jury and (b) Executive has not been granted
formal immunity. By agreeing to cooperate Executive does not waive any of his
constitutional rights or attorney-client or attorney work product privileges and
any assertion of such rights or privileges shall not be considered a violation
of this Agreement. The Executive agrees that he will notify the Company promptly
and in writing in the event that he is served with a subpoena or other such
request for information or documents from a third party concerning the Company.

            6.2 The Executive agrees that, for the period from the date of this

convenient times to the Senior Executives and the Board of Directors of the
Company from time to time for purposes of providing information and assistance
with respect to the operation of the Company, provided that in no event shall
the Executive be required to devote more than four hours per calendar month in
providing such assistance.

            6.3 The Company agrees that the Company and its lawyers will
cooperate with Executive by providing him and his lawyers with reasonable access
to copies of all business records of the Company, to which the Executive would
have been entitled to access in the ordinary course of business during the
period in which Executive was employed by the Company or served/serves as
Chairman or a member of the Company's Board of Directors, that are necessary to
the Executive's defense of the proceedings described in Section 4.1 above or any
other indemnified activity for so long as such proceedings continue.

      7. NON-DISCLOSURE AND NON-COMPETITION. The Executive acknowledges and
reaffirms his obligations with respect to intellectual property and
non-competition, as stated more fully in the Confidentiality and Proprietary
Information Agreement dated May 16, 1990 (the "Confidentiality Agreement") and

each of which remains in full force and effect.

which is in his possession or control, excepting only the leased automobile

lease term) and the computer hardware he is allowed to retain pursuant to this
Agreement. The Executive further agrees to leave intact all electronic Company
documents, including those which he developed or helped develop during his
employment.

      9. CONFIDENTIALITY. To the extent permitted by law, the Executive
understands and agrees that the terms and contents of this Agreement, and the

in writing by the authorized agent of each party.

this Agreement.

            15.5 APPLICABLE LAW. This Agreement shall be interpreted and
construed by the laws of the Commonwealth of Massachusetts, without regard to
conflict of laws provisions. Executive hereby irrevocably submits and
acknowledges and recognizes the jurisdiction of the courts of the Commonwealth
of Massachusetts, or if appropriate, a federal court located in Massachusetts
(which courts, for purposes of this Agreement, are the only courts of competent
jurisdiction), over any suit, action or other proceeding arising out of, under
or in connection with this Agreement or the subject matter hereof.

            15.6 FURTHER ASSURANCES. The Company and Executive agree to execute,
acknowledge, deliver and perform, or cause to be executed, acknowledged,
delivered or performed, at any time, or from time to time, as the case may be,
all such further documents, acts, deeds, assignments, transfers, conveyances,
powers of attorney and assurances as may be necessary or proper to carry out the
provisions or intent of this Agreement.

            15.7 SEVERABILITY. If any one or more of the terms, provisions,
covenants or restrictions of this Agreement shall be determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions of this Agreement shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated. If, moreover, any one or more of the provisions contained in this
Agreement shall for any reason be determined by a court of competent
jurisdiction to be excessively broad as to duration, geographical scope,
activity or subject, it shall be construed by limiting or reducing it so as to
be enforceable to the extent compatible with then applicable law.
