                AMENDMENT NO. 3 TO REGISTRATION RIGHTS AGREEMENT

         This Amendment No. 3 dated as of December 30, 1998 further amends the

to the registration of the common stock of the Company issuable upon conversion
thereof comparable to and integrated with the rights of the original parties to

         In consideration of the foregoing and other good and valuable

parties hereto agree to amend the Agreement as follows:

         1.       The following definitions are hereby added to Section 2 of the

         2.       The definition of "Common Shares" as set forth in Section 2 of
the Agreement is hereby deleted in its entirety and superseded by the following:

                  "Common Shares" shall mean shares of common stock of the
