intent to withdraw such Part Payment signed and notarized by each Seller. Subject to the satisfaction of the notification provision provided in the previous sentence, Purchaser authorizes Sellers to withdraw from the Company the Part Payments of the
Second Cash Installment which the Company becomes obligated to pay to Sellers pursuant to this Section 5(a). To the extent the Second Cash Installment is received by Sellers in whole or in part from the Part Payments pursuant to this
Section 5, the aggregate of such Part Payments shall fulfill Purchasers obligations under the Agreement to make such Second Cash Installment payment to the extent of the total amount of the Part Payments so received by Sellers. Until the

tax returns for 2006 without the IRC Section 338(h)(10) election as specified in Section 2 above, and further provided that the amount Purchaser shall be required to pay for all such accountants fees shall not exceed
$11,000. In addition, Purchaser shall pay to Sellers the amounts incurred by them for their attorneys fees in connection with the negotiation and completion of the transactions contemplated by this Addendum; provided, however, that the amount

8.14 Non-Receipt of Benefit. Notwithstanding anything contained herein to the contrary, in the event that the IRS fully and finally objects to, or
rejects, the Form 8023, and such decision by the IRS becomes final, either because no Party appeals such decision within the time permitted for an appeal or because, upon the conclusion of all appeals of such decision timely pursued by any of the
Parties, a final decision is rendered affirming the decision of the IRS such that making the IRC Section 338(h)(10) election with respect to the transactions contemplated by the Agreement is not effective and if, as a result thereof, Sellers
either (i) are not required to pay to any taxing authority all or a portion of the 338 Payment and/or (ii) recover all or a portion of the 338 Payment from the taxing authorities to whom they have paid any portion of the 338 Payment, then
