        4.    Covenants Relating to Collateral.    Debtor hereby agrees (a) to perform all acts that may be necessary
to maintain, preserve, protect and perfect the Collateral, the Lien granted to Secured Party therein and the perfection and priority of such Lien; (b) without 30 days' prior written
notice to Secured Party, not to change Debtor's legal name or primary residence, (c) to procure, execute and deliver from time to time any endorsements, assignments, financing statements and
other writings reasonably deemed necessary or appropriate by Secured Party to perfect, maintain and protect its Lien hereunder and the priority thereof and to deliver promptly to Secured Party all
certificated securities constituting Collateral; and (d) except as explicitly permitted by this Security Agreement, not to surrender or lose possession of (other than to Secured Party), sell,
encumber, lease, rent, or otherwise dispose of or transfer any Collateral or right or interest therein, and to keep the Collateral free of all Liens. 

        5.    Authorized Action by Secured Party.    Debtor hereby irrevocably appoints Secured Party as its
attorney-in-fact (which appointment is coupled with an interest) and agrees that Secured Party may perform (but Secured Party shall not be obligated to and shall incur no
liability to Debtor or any third party for failure so to do) any act which Debtor is obligated by this Security Agreement to perform, and to exercise such rights and powers as Debtor might exercise
with respect to the Collateral, including the right to (a) collect by legal proceedings or otherwise and endorse, receive and receipt for all dividends, interest, payments, proceeds and other
sums and property now or hereafter payable on or on account of the Collateral; (b) deposit, surrender, accept, hold or apply other property in exchange for the Collateral; (c) make any
compromise or settlement, and take any action it deems advisable, with respect to the Collateral; (d) insure, process and preserve the Collateral; and (e) execute UCC financing
statements and other documents, instruments and agreements required hereunder; provided, however, that
Secured Party shall not exercise any such powers granted pursuant to subsections (a) through (c) prior to the occurrence of an Event of Default and shall only exercise such powers during
the continuance of an Event of Default. Debtor agrees to reimburse Secured Party upon demand for any reasonable costs and expenses, including attorneys' fees, Secured Party may incur while acting as
Debtor's attorney-in-fact hereunder, all of which costs and expenses are included in the Obligations. It is further agreed and understood between the parties hereto that such
care as Secured Party gives to the safekeeping of its own property of like kind shall constitute reasonable care of the Collateral when in Secured Party's possession. 

        6.    Default and Remedies.    

        (a)    Default.    Debtor shall be deemed in default under this Security Agreement upon the occurrence and during the
continuance of an Event of Default. 

        (b)    Remedies.    Upon the occurrence and during the continuance of any such Event of Default, Secured Party shall
have the rights of a secured creditor under the UCC, all rights granted by this Security Agreement and by applicable law. Debtor hereby agrees that ten (10) days' notice of any intended sale or
disposition of any Collateral is reasonable. 

        (c)    Sale of Pledged Securities.    Debtor acknowledges and recognizes that Secured Party may be unable to effect a
public sale of all or a part of the Pledged Securities and may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obligated to agree, among other
things, to acquire the Pledged Securities for their own account, for investment and not with a view to the distribution or resale thereof. Debtor acknowledges that any such private sales may be at
prices and on terms less favorable to Secured Party than those of public 

3

 

sales,
and agrees that so long as such sales are made in good faith such private sales shall be deemed to have been made in a commercially reasonable manner and that Secured Party has no obligation to
delay sale of any Pledged Securities to permit the issuer thereof to register it for public sale under any applicable securities laws. 

        7.    Miscellaneous.    

        (a)    Notices.    Except as otherwise provided herein, all notices, requests, demands, consents, instructions or
other communications to or upon Debtor or Secured Party under this Security Agreement shall be by telecopy or in writing and telecopied, mailed or delivered to each party at telecopier number or its
address set forth below (or to such other telecopy number or address as the recipient of any notice shall have notified the other in writing). All such notices and communications shall be effective
(a) when sent by Federal Express or other overnight service of recognized standing, on the business day following the deposit with such service; (b) when mailed, by registered or
certified mail, first class postage prepaid and addressed as aforesaid through the United States Postal Service, upon receipt; (c) when delivered by hand, upon delivery; and (d) when
telecopied, upon confirmation of receipt.
