        <footnote id="F5">Granted 8/27/2010 under the Plan, vesting when certain defined performance milestones for the Company's Brick Business Unit are achieved.</footnote>
        <footnote id="F6">The replacement options vest over a five year period in equal installments.</footnote>
        <footnote id="F7">Pursuant to the Exchange Offer, Replacement Options granted on 6/17/2013 in exchange for certain options with vesting tied to the performance of the Brick Business Unit were awarded with five escalating exercise prices, as shown above in Table II, each with a separate vesting schedule: those with an exercise price of $6.29 fully vest on the first anniversary of grant, those with an exercise price of $7.34 fully vest on the second anniversary, those with an exercise price of $8.38 fully vest on the third anniversary, those with an exercise price of $9.43 fully vest on the fourth anniversary, and those with an exercise price of $10.48 fully vest on the fifth anniversary.</footnote>
        <footnote id="F8">The reporting person is filing this amendment to report the correct amount of options acquired on June 17, 2013.  The Form 4/A filed on October 20, 2014, amended the original Form 4 of June 19, 2013, which reflected the acquisition, pursuant to Exchange Offer and in accord with the Plan, of options to purchase 20,000 shares at a price of $7.34, 20,000 shares at a price of $8.38, 20,000 shares at a price of $9.43, and 20,000 shares at a price of $10.48.  As disclosed on the Form 4/A filed on October 20, 2014 the Company determined, subsequent to the grants associated with the Exchange Offer, an aggregate amount of options to purchase 69,514 shares was not validly granted during 2013 pursuant to the Plan, because the amount exceeded the Plan's limit on the number of options that may be granted to any individual within any calendar year.  Accordingly, the attempted grant of these excess options was ineffective, and the options were never granted to the reporting person.</footnote>
        <footnote id="F9">The Form 4/A filed on October 20, 2014 amended the original Form 4 of June 25, 2013, indicating that options to purchase 695 shares at a strike price of $7.34 were not validly granted.  However, the Company subsequently determined options to purchase 2,459 shares at a price of $7.34 were not validly granted.  As such, the revised 17,541 figure shown above in Table II reflects the correct amount of options validly granted under the provisions of the Plan</footnote>
