and the Company dated as of May 14, 1999 (the "Agreement"),
including each note attached thereto as Exhibit A (the "Note"), and

      2.   The parties agree that the interest due on the Note held
by the Lenders who are signatories hereto as of August 15, 1999
shall be deferred until November 15, 1999 and shall become due and
payable on such date, together with the interest otherwise due on
each Note on such date.

      3.    In consideration thereof, each Lender unconditionally
and irrevocably waives the Company's default under Sections 1, 3(a)
and 4(a), of each Note and Section 2.2(c)(i) of the Pledge/Security
Agreement, including, without limitation, any and all rights and
remedies set forth therein, effective as of the date hereof.

       Re:  Waiver of Default under Agreements
            ----------------------------------

 Ladies and Gentlemen:

       Reference is made to the Loan Agreement between the Lenders and the
 Company dated as of May 14, 1999 (the "Agreement"), including each note
 attached thereto as Exhibit A (the "Note"), and the Pledge/Security
 Agreement attached thereto as Exhibit B (the "Pledge/Security Agreement").

       As an inducement for the Company to consummate an offering of its
 common stock pursuant to the Confidential Private Placement Memorandum
 dated January 24, 1999, as amended (the "Offering"), the Company and each
 Lender agree as follows:

       1.   The Company hereby delivers to each Lender his, her or its pro
 rata share of default stock purchase warrants to purchase an aggregate of
 300,000 shares of the Company's common stock at an exercise price of $0.25
 per share in the form of Exhibit 2 to the Pledge/Security Agreement,
 receipt of which is hereby acknowledged.

       2.   In addition to the foregoing, the Company hereby delivers to
 each Lender his, her or its pro rata share of 200,000 shares of the
 Company's common stock, which are subject to applicable securities laws
 restrictions, receipt of which is hereby acknowledged.

       3,   Section 3(b) of each Note shall be amended to read as follows
 effective as of May 14, 1999:

       "Notwithstanding anything contained herein to the contrary, this Note
      shall be mandatorily prepaid in an amount equal to 25% of the gross
      proceeds received by the Maker from any and all closings of an
      offering of its securities, whether through one or more private
      placement or secondary public offerings, which prepayment shall be
      made upon the closing of any such offering, any gross proceeds
      received by the Company from any such offering on or before December
      31, 1999 shall be due and payable on December 31, 1999."

       4.   Section 5.6 of the Pledge/Security Agreement shall be amended to
 read as follows, effective as of May 14, 1999:



       "Additional Remedies upon Certain Defaults.  Notwithstanding anything
      contained in this Agreement to the contrary, if there is an event of
      default under Section 2.2(c)(v) hereof and as the exclusive remedy in
      such case.  Pledgor shall grant to each Pledgee his pro rata share
      (computed based on the ratio of the principal amount of his Note to
      the principal amount of all Notes originally issued) of additional
      warrants, substantially in the form attached hereto as Exhibit 2, to
      purchase additional shares of the common stock of Pledgor (the
      "Default Warrant Shares") at the rate of Three Hundred Thousand
      (300,000) Default Warrant Shares for each such event of default under
      Section 2.2(c)(v) hereof; provided, however, that the number of
      Default Warrant Shares shall not exceed Nine Hundred Thousand
      (900,000) of such shares in the aggregate.  The representations and
      warranties of each Pledgee set forth in Section 3 of such Pledgee's
      Subscription Agreement shall be true and correct with respect to such
      Default Warrant Shares on the date of such grant and as the exclusive
      remedy in such case after 2.2(c)(v) hereof."

       In consideration of the foregoing amendments, each Lender
 unconditionally and irrevocably waives the Company's default under Sections
 3(b), 4(a), 4(b) and 4(e)(i) of each Note and Section 2.2(c)(i), (ii), and
 (v)(i) of the Pledge/Security Agreement, including, without limitation, any
 and all rights and remedies set forth therein, effective as of the date
 hereof.

       Except as amended as set forth herein, the Agreement, each Note and
 the Pledge/Security Agreement shall continue in full force and effect.
