         delivery of shares of Common Stock in accordance with Article 2 of the
         Stellar Purchase Agreement."

Rights Agreement is amended to add the following sentence at the end thereof:

         "Notwithstanding anything in this Agreement to the contrary, a Stock
         Acquisition Date shall not be deemed to have occurred solely as the
         result of (i) the execution and delivery of the Stellar Purchase
         Agreement, or (ii) the issuance and delivery of shares of Common Stock
         in accordance with Article 2 of the Stellar Purchase Agreement."

full force and effect and shall be otherwise unaffected hereby.

         (c) This Amendment may be executed in two or more counterparts, each of
which shall be deemed to be an original, but all for which together shall
constitute one and the same instrument.

         (d) This Amendment shall be deemed to be a contract made under the laws
