transferee of the terms and conditions of the option.

or without cause, or due to the act, death, Disability, or retirement of the
participant, the participant's right to exercise the option shall terminate and
all rights thereunder shall cease.  (b) If, on or after the date that an option

shall have the right, prior to the earlier of (i) the expiration of the option
or (ii) the day which is three months after the date on which the Participant
ceased to be a director of the Company, to exercise the option to the extent
that it was exercisable and is unexercised on the date the participant ceased
to be a director of the Company, subject to any other limitation on the
exercise of the option in effect at the date of exercise.  (c) If, on or after
the date that an option shall have become exercisable, the participant shall
die or become Disabled which a director of the company or while such option

estate of the participant (as the case may be), or the person or persons to
whom the option shall have been transferred by will or by the laws of descent
and distribution, shall have the right, prior to the earlier of (i) the
expiration of the option or (ii) the day which is one year after the date of
the participant's death or Disability to exercise the option to the extent that

consolidation, split-up, spin-off, combination, repurchase, or exchange of
Common Stock, or other securities of the Company, issuance of warrants or other
rights to purchase Common Stock or other securities of the Company, or other
similar corporate transaction or event affects the common Stock such that an
adjustment is determined by the Board of Directors  to be appropriate in order
to prevent dilution or enlargement of the benefits or potential benefits
intended to be made available under the Plan, then the Board of Directors
shall, in such manner as it may deem equitable, adjust any or all of (a) the
number and type of shares of Common Stock or other securities which thereafter
may be made the subject of options, (b) the number and type of shares

exercise price with respect to any option, or, if deemed appropriate, make
provision for a cash payment to the holder of an outstanding option; provided,
however, that the number of shares of Common Stock subject to any option shall
always be a whole number.

         11.  RIGHTS PRIOR TO ISSUANCE OF SHARES.

         No participant shall have any rights as a shareholder with respect to
any shares covered by an option until the issuance of a stock certificate to
the participant for such shares.  No adjustment shall be made for dividends or
other rights with respect to such shares for which the record date is prior to
the date such certificate is issued.

         12.  TERMINATION AND AMENDMENT.

Plan, at any time.  No Option shall be granted under the Plan ten years after

shareholders, whichever is earlier.  Termination of the Plan shall not affect
the rights of the holders of any options previously granted.

time.  No amendment, modification, or termination of the Plan shall in any
manner affect any option granted under the Plan without the consent of the
participant holding the option.

         The Plan shall be subject to the approval of the holders of at least a
majority of the shares of Common Stock of the Company present and entitled to
vote at a meeting of shareholders of the Company.   No option granted under the
Plan may be exercised in whole or in part until the Plan has been approved by
