NOW THEREFORE, effective March 4, 2015, the Plan is hereby amended as follows:
1. Section 12 of the Plan is hereby amended and restated in its entirety as
follows:
“12. Formula Option and Restricted Stock Grants to Outside Directors.
(a) General. All grants of Options and Restricted Stock to Outside Directors
pursuant to this Section 12 will be automatic and nondiscretionary, except as
otherwise provided herein, and will be made in accordance with the following
provisions:
(b) Type of Awards. All Options granted pursuant to this Section will be
Nonstatutory Stock Options and, except as otherwise provided herein, will be
subject to the other applicable terms and conditions of the Plan (including,
without limitation, Section 6(d)(ii)-(vi)). Except as otherwise provided herein,
all Restricted Stock granted pursuant to this Section will be subject to the
other applicable terms and conditions of the Plan.
(c) No Discretion. No person will have any discretion to select which Outside
Directors will be granted awards of Options and Restricted Stock under this
Section or to determine the number of Shares to be covered by such Awards
(except as provided in Sections 12(i) and 16).
(d) Initial Award. Each person who first becomes an Outside Director will be
automatically granted: (i) an Option to purchase a number of Shares equal to the
product of (I) 20,000 multiplied by (II) a fraction, the numerator of which is
the number of days in the period beginning on the date such person first becomes
an Outside Director and ending on the date of the first annual meeting of the
stockholders of the Company thereafter, and the denominator of which is 365 (the
“Fraction”) rounded down to the nearest whole number (the “Initial Option”) and
(ii) and Award of Restricted Stock equal to the product of (I) $40,000 divided
by the Fair Market Value of a Share on the date such person first becomes an
Outside Director multiplied by (II) the Fraction rounded down to the nearest
whole number (the “Initial Restricted Stock Award”). The Initial Option and the
Initial Restricted Stock Award shall be granted on or about the date on which
such person first becomes an Outside Director, whether through election by the
stockholders of the Company or appointment by the Board to fill a vacancy;
provided, however, that an Inside Director who

--------------------------------------------------------------------------------

ceases to be an Inside Director, but who remains a Director, will not receive an
Initial Option or an Initial Restricted Stock Award.
(e) Annual Option. Each Outside Director will be automatically granted an Option
to purchase twenty thousand (20,000) Shares (an “Annual Option”) on each date of
the annual meeting of the stockholders of the Company.
(f) Option Terms. The terms of each Option granted pursuant to this Section 12
will be as follows:
(i) The term of the Option will be ten (10) years, subject to earlier
termination as set forth in the Award Agreement.
(ii) The exercise price per Share will be one hundred percent (100%) of the Fair
Market Value per Share on the date of grant of the Option.
(iii) Subject to Section 16, the Option will vest and become exercisable as to
one hundred percent (100%) of the Shares subject to the Option on the earlier of
the first anniversary of the date of grant or the date of the first annual
meeting of the stockholders of the Company immediately following the date of
grant, in either case, provided that the Participant continues to serve as a
Director through such date.
(g) Annual Restricted Stock Award. Each Outside Director will be automatically
granted Restricted Stock having a Fair Market Value of forty thousand dollars
($40,000) (an “Annual Restricted Stock Award”) on each date of the annual
meeting of the stockholders of the Company.
(h) Restricted Stock Terms. Notwithstanding anything to the contrary in Section
7(b), the Period of Restriction applicable to each Initial Restricted Stock
Award and each Annual Restricted Stock Award shall lapse on the earlier of the
first anniversary of the date of grant or the date of the first annual meeting
of the stockholders of the Company immediately following the date of grant, in
either case, provided that the Participant continues to serve as a Director
through such date.
(i) Adjustments. The Administrator in its discretion may change and otherwise
revise the terms of Options and Restricted Stock to be granted under this
Section 12, including, without limitation, the number of Shares and exercise
prices thereof, for Options and Restricted Stock granted on or after the date
the Administrator determines to make any such change or revision.
(j) Other Awards. Nothing in this Section 12 will limit the ability of the
Administrator to grant any other Award under the Plan to Outside Directors in
addition to the Options and Restricted Stock that are granted to them under this
Section 12.”
2. Except as expressly amended hereby, the Plan shall remain unmodified and in
full force and effect.
