(c) Sale of Assets. In the event that iCAD sells any assets in excess of $500,000 in the aggregate during the Revenue Participation Term the proceeds of which are not recorded as “Revenues” in accordance with GAAP, then in each such case iCAD shall pay the Purchasers an aggregate amount equal to the Asset Sale Amount, payable 37.28% to Private Design Fund II, 7.8% to DSS and 54.92% to Horizon, in each case rounded to the nearest cent ($0.01).

Upon not less than fourteen days’ written notice, the Purchasers shall have the right to audit the books and records of iCAD relating to sales or other transactions included in Revenues for the purposes of determining the correctness of iCAD’s computation and payment of the Revenue Participation Payment. Such audit may not be conducted more than once in any calendar year and shall be conducted during normal business hours by a national public accounting firm selected by the Purchasers at its cost and reasonably acceptable to iCAD, provided that such accounting firm enters into a reasonable confidentiality agreement prior to commencing any such audit. iCAD shall provide such accounting firm with access to all pertinent books and records and shall reasonably cooperate with such accounting firm’s efforts to conduct such audits.
