Without limiting the generality of the foregoing, in any such event Secured Party may, in its sole discretion, (i) in accordance with applicable securities laws, proceed to make such private sale notwithstanding that a registration statement for the purpose of registering such Collateral or part thereof could be or shall have been filed under the Act; (ii) approach and negotiate with a single possible purchaser to effect such sale; and (iii) restrict such sale to a purchaser who will represent and agree that such purchaser is purchasing for its own account, for investment, and not with a view to the distribution or sale of such Collateral or part thereof. In addition to a private sale as provided above in this Section 7(b), if any of such Collateral shall not be freely distributable to the public without registration under the Act at the time of any proposed sale hereunder, then Secured Party shall not be required to effect such registration or cause the same to be effected but may, in its sole discretion (subject only to applicable requirements of law), require that any sale hereunder (including a sale at auction) be conducted subject to such restrictions as Secured Party may, in its sole discretion, deem necessary or appropriate in order that such sale (notwithstanding any failure so to register) may be effected in compliance with the Bankruptcy Code and other laws affecting the enforcement of creditors’ rights and the Act and all applicable state securities laws.

(c) Grantor also agrees to pay all fees, costs and expenses of Secured Party, including, without limitation, attorneys’ fees, incurred in connection with the enforcement of any of its rights and remedies hereunder.
