|9. |  | BANKS RIGHTS AND REMEDIES
|-- |  | --------------------------



|9.1 |  | Rights and Remedies.
|--- |  | --------------------



When an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following:



(a) Declare all Obligations immediately due and payable (but if an Event of
Default described in Section 8.5 occurs all Obligations are immediately due and payable without any action by Bank);



(b) Stop advancing money or extending credit for Borrowers benefit under this Agreement or under any other agreement between Borrower and Bank;



(c) Settle or adjust disputes and claims directly with account
debtors for amounts, on terms and in any



10



---

order that Bank considers advisable;



(d) Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower will assemble the
Collateral if Bank requires and make it available as Bank designates. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which
appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Banks rights or remedies;



(e) Apply to the Obligations any (i) balances and deposits of Borrower it
holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower;



(f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Bank is granted a non-exclusive, royalty-free license or other right to use, without charge,
Borrowers labels, Patents, Copyrights, Mask Works, rights of use of any name, trade secrets, trade names, Trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of,
advertising for sale, and selling any Collateral and, in connection with Banks exercise of its rights under this Section, Borrowers rights under all licenses and all franchise agreements inure to Banks benefit; and



(g) Dispose of the Collateral according to the Code.



|9.2 |  | Power of Attorney.
|--- |  | ------------------



Effective only when an Event of Default occurs and continues, Borrower irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrowers
name on any checks or other forms of payment or security; (ii) sign Borrowers name on any invoice or bill of lading for any Account or drafts against account debtors, (iii) make, settle, and adjust all claims under Borrowers insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits.
Bank may exercise the power of attorney to sign Borrowers name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred. Banks appointment as
Borrowers attorney in fact, and all of Banks rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Banks obligation to provide Credit Extensions terminates.



|9.3 |  | Accounts Collection.
|--- |  | --------------------



When an Event of Default occurs and continues, Bank may notify any Person owing Borrower money of Banks security interest in the funds and verify
the amount of the Account. Borrower must collect all payments in trust for Bank and, if requested by Bank, immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit.



|9.4 |  | Bank Expenses.
|--- |  | --------------



If Borrower fails to pay any amount or furnish any required proof of payment to third persons, Bank may make all or part of the payment or obtain
insurance policies required in Section 6.5, and take any action under the policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then applicable rate and secured by the
Collateral. No payments by Bank are deemed an agreement to make similar payments in the future or Banks waiver of any Event of Default.



|9.5 |  | Banks Liability for Collateral.
|--- |  | --------------------------------



If Bank complies with reasonable banking practices and the Code, it is not liable for: (a) the safekeeping of the Collateral; (b) any loss or damage to
the Collateral; (c) any diminution in the value of the Collateral; or (d) any



11



---

act or default of any carrier, warehouseman, bailee, or other person. Borrower bears all risk of loss, damage or destruction of the Collateral.



|9.6 |  | Remedies Cumulative.
|--- |  | --------------------



Banks rights and remedies under this Agreement, the Loan Documents, and all other agreements are cumulative. Bank has all rights and remedies
provided under the Code, by law, or in equity. Banks exercise of one right or remedy is not an election, and Banks waiver of any Event of Default is not a continuing waiver. Banks delay is not a waiver, election, or acquiescence.
No waiver is effective unless signed by Bank and then is only effective for the specific instance and purpose for which it was given.



|9.7 |  | Demand Waiver.
|--- |  | --------------



Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrower is liable.



|10. |  | NOTICES
|--- |  | -------



All notices or demands by any party about this Agreement or any other related agreement must be in writing and be personally delivered or sent by an
overnight delivery service, by certified mail, postage prepaid, return receipt requested, or by telefacsimile to the addresses set forth at the beginning of this Agreement. A party may change its notice address by giving the other party written
notice.



|11. |  | CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER
|--- |  | ------------------------------------------



California law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of
the State and Federal courts in Los Angeles County, California.



BORROWER
AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL
INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

of, or any interest in, Banks obligations, rights and benefits under this Agreement.
