                                   WITNESSETH:

     WHEREAS, Employer has previously employed the Employee as its Chairman of
the Board of Directors ("Chairman") and Chief Executive Officer (" CEO")under

Amendment #1 to Employment Agreement                             Ref: 2001031901
Between InforMedix and Bruce A. Kehr, M.D.                     Page 2 of 9 Pages

     A.   Commencing on the Effective Date, Employer (or at Employer's option,
          any subsidiary or affiliate thereof)shall pay to the Employee an
          annual salary of $200,000.00 (two hundred thousand dollars), with a
          minimum of $40,000 (forty thousand dollars)to be paid in cash (the
          "Salary"). The Salary will be paid in biweekly installments.

     B.   If it is determined by the Executive Committee of the Board of
          Directors of Employer (the "Executive Committee")that there are
          insufficient funds to pay any portion of the Salary in cash, then the
          portion of the Salary not paid in cash, up to the full amount of the
          Salary, will be paid in the form of non-qualified stock options of
          Employer, as defined in Employer's Omnibus Stock Plan ("Plan"), with
          an exercise price per share of $1.00 (one dollar), which vest
          immediately when granted, and become exercisable one year after the
          date of each grant (the "Salary Options").

          (1)  The number of shares subject to the Salary Options (the "Salary
               Option Share(s)") will be determined by dividing the amount of
               the Salary not to be paid in cash, by the per share price of
               InforMedix Common Stock on the date of grant of the Salary
               Options (on the Effective Date of this Amendment #1 it is $10.00
               [ten dollars] per share), less the $1.00 (one dollar) exercise
               price, or $9.00 (nine dollars).

          (2)  For example, were $160,000.00 (one hundred sixty thousand
               dollars) of Salary not to be paid in cash, then, Salary Options
               to purchase 17,777.777 (seventeen thousand, seven hundred
               seventy-seven point seven seven seven) Salary Option Shares would
               be granted.

          (3)  If Employer sells, or otherwise cause to be issued, any shares of
               InforMedix Common Stock, or other instruments convertible into
               InforMedix Common Stock, for less than $10.00 (Ten Dollars) per
               share (the "Revised Price Per Share"), then Employer shall issue
               to Purchaser, additional Salary Option Shares so that the Salary
               Option Shares equal the amount of the Salary not to be paid in
               cash, divided by the Revised Price Per Share.

     C.   Employer, at the election of the Board of Directors, may exercise a
          call on some or all of the issued, but unexercised Salary Options held
          by Employee as of the date of such call (a "Call"), and purchase those
          Salary Options from Employee within 60 (sixty) days of a Call, at a
          purchase price per Salary Option Share equal to the then-effective
          market price per share of InforMedix Common Stock, but in no event
          less than $10.00 (Ten Dollars)per share, less the $1.00 exercise
          price, and subject to the terms and conditions set forth below.

          (1)  At any time during a calendar year, Employer may exercise a Call
               to purchase some or all of the unexercised Salary Options earned
               by

               Employee at any time in that calendar year, up to and including
               the date of the exercise of a Call.

          (2)  Up to and including March 31St of any year, Employer may exercise
               a Call to purchase some or all of the unexercised Salary Options
               earned by Employee at any time in the preceding calendar year.

          (3)  Nothing in this Subsection of the Employment Agreement shall
               authorize or permit Employer to purchase InforMedix Common Stock
               owned by Employee which had previously been subject to Salary
               Options of Employee, and which had previously been exercised by
               Employee and converted to InforMedix Common Stock.

3.  Performance-Based Stock Options and Vesting.

     B.   The PB Options to purchase InforMedix Common Stock will vest based
          upon the attainment of pre-determined and pre-assigned performance
          targets, as determined by the Board of Directors.

     C.   The PB Options will be for a three-year period, with one-third of the
          shares subject to the PB Options (the "PB Option Share(s)"), vesting

     D.   The number of PB Option Shares subject to the PB Options for each
          Grant, will be 11,667, which will be eligible for vesting in each of
          the three (3)years of each Grant.

     E.   After the date that the Employee ceases to be an employee or director

               a result of which the outstanding securities of the class of
