Explanation of Responses:
On July 10, 1998, the Reporting Person filed on Form 3 indicating that the Reporting Person had entered into a Common Stock
Purchase Agreement, Warrant Agreement and Note Purchase Agreement pursuant to which it might acquire up to 2,049,572 shares of
the Issuer's Common Stock, Warrants to acquire up to 683,191 additional shares, and Convertible Senior Secured Fixed Rate Notes,
which, upon conversion, the Issuer would issue up to 797,619 shares of Common Stock. The transactions contemplated by the Common
Stock Purchase Agreement, the Warrant Agreement and the Note Purchase Agreement closed on August 4, 1998, at which time the
Reporting Person acquired the Common Stock, Warrants and Notes reported herein. The Reporting Person has no right to acquire any
additional securities of the Issuer under the Common Stock Purchase Agreement, the Warrant Agreement or the Note Purchase
Agreement, though such agreements impose no limitation on future acquisitions or dispositions of such shares by the Reporting
Person.
On August 4, 1998, the Reporting Person entered into Participation Agreements with certain Swiss investors. This filing shall
not be deemed an admission that the Reporting Person presently is, for purposes of Section 16 of the Act, Beneficial Owner of any
shares of the Issuer's Common Stock that certain Swiss investors would be entitled to upon conversion of the Notes. Certain
Swiss investors, who are not Reporting Persons, would receive an aggregate of 37,897 shares of the Issuer's Common Stock upon
their election to exercise their conversion rights.
