Introduction

This Agreement contains the terms governing an account(s) in my name for the purchase or sale of property. In the Agreement, “I,” “me” or “my” means each person who signs below. “You,” “your” or “UBS Financial Services” means UBS Financial Services Inc., its successor firms, subsidiaries, correspondents or affiliates, or employees. “Property” means all securities, including but not limited to monies, stocks, options, bonds, notes, futures, contracts, commodities, certificates of deposit and other obligations, contracts or securities.

Applicable Rules and Regulations

All transactions for me shall be subject to the constitution, rules, regulations, bylaws, interpretations, customs and usages of the exchange or market and its clearing house, if any, where the transactions are executed. Such transactions are also subject, where applicable, to the provisions, rules and regulations of the Securities and Exchange Commission, the Commodity Futures Trading Commission, the Board of Governors of the Federal Reserve System in existence at this time and as later amended and supplemented.

Amendment or Waiver

I agree that you may change the terms of this agreement at any time upon prior written notice to me. By continuing to accept the services offered by you, I indicate to you my acceptance of these changes. If I do not accept the changes, I must notify you in writing of my refusal and my account will be cancelled. However, I will remain liable for any outstanding Debits and/or Charges on my account.

Transactions and Settlements

All orders for the purchase and sale of any property will be given by me and executed with the distinct understanding that an actual purchase or sale is intended and that it is my intention and obligation in every case to deliver property to cover any and all sales and in the case of purchases to receive and pay for property that I will do so upon your demand. In case you make a short sale of any property at my direction or in case I fail to deliver to you any property which you have sold at my direction, you are authorized to borrow the property necessary to enable you to make delivery to the purchaser and I agree to be responsible for the cost or loss you may incur, or the cost of obtaining the property if you are unable to borrow it. No settlement of my account(s) may occur without your first receiving all property for which the account is short and all property in which the account(s) are long being paid for in full and the property then delivered. You and your correspondents are my constituted agents to complete all such transactions and are authorized to make advances and expend monies as are required.

Marking Sell Orders Long or Short

When placing with you any sell order for a short account, I will designate it as such and hereby authorize you to xxxx the order as being “short.” When placing with you any order for a long account, I will designate it as such and hereby authorize you to xxxx the order as being “long.” Any sell order which I shall designate as being for a long account, is for property which is owned by me and, if you are unable to deliver this property from any account(s), the placing of the order will constitute my representation that the property will be delivered as required and that I will reimburse you for any expense incurred.

Binding Order

Any order which I give shall be binding upon me, and (my/our) personal representative until you receive notice of my death. Such death and notice will not affect your right to take any action which you could have taken if I had not died.

Lien Provisions

All property held or purchased shall be subject to a lien in your favor for the discharge of all my indebtedness and any other obligations that I may owe to you, however and whenever arising, and may be held by you as security for the payment of any such obligations or indebtedness to you in any account you maintain for me including any accounts in which I may have an interest. You are authorized without notice to me whenever you deem it advisable from time to time (a) to transfer interchangeably between any accounts I have with you any or all of the Property so held, without regard to whether you have in your possession or subject to your control other Property of the same kind and amount; (b) in the usual course of business pledge, repledge, hypothecate (either for the amount I owe you or for a greater or lesser sum) and lend the same to you as broker or to others from time to time, separately or commingled with Property carried for other clients and you shall not be required to deliver to me the same Property but only Property of the same kind and amount.

Payment of Indebtedness Upon Demand

I shall at all times be liable for the payment of any amounts advanced, any debit balance or other obligations owing in any of my account(s) with you and I shall be liable to you for any deficiency remaining in any such account(s) in the event of the liquidation thereof, in whole or in part, by you or by me. I shall make payment of any such debit balance, obligation, deficiency, indebtedness, including interest and commissions, upon demand and any costs of collection, including attorney’s fees, if incurred by you.

Interest Provision

All amounts advanced and other balances due shall be charged interest in accordance with your usual custom, which may include the compounding of interest, including any increases in rates which reflect adjustments in the UBS Financial Services Base Loan Rate, and such other charges as you may make to cover your facilities and extra services. Payment of all amounts advanced and other balances due, together with the interest thereon, shall be made by me to you at any of your offices which will act as my agent for the transmittal of such amounts and other balances due to you at New York, New York.

I HAVE READ AND UNDERSTAND THE STATEMENT OF CREDIT PRACTICES DESCRIBING INTEREST CHARGES PRINTED ON THE REVERSE SIDE.

Sub-Agents

10.

You may employ sub-brokers and shall be responsible only for reasonable care in their selection. You may deal with market makers or members of any exchange known as specialists or known as odd lot dealers and in the execution of my orders they may act as sub-brokers for me and may also buy or sell the property for themselves as dealers for their own account.

Margin Requirements

11.

I agree to maintain in account(s) with you such positions and margin as required by all applicable statutes, rules, regulations, procedures, and customs, or as you deem necessary or advisable, and where applicable, to satisfy any and all margin calls issued in connection with such business.

Liquidations and Covering Positions

12.

You shall have the right in accordance with your general policies regarding your margin maintenance requirements in existence at the time or; if in your discretion you consider it necessary for your protection to require additional collateral or the liquidation of any account of mine, or; in the event a petition in bankruptcy, or for appointment of a receiver is filed by or against me, or; an attachment is levied against the account(s) of mine, or; in the event of my death; to sell any or all property in the account(s) of mine with you, whether carried individually or jointly with others, to buy any or all property which may be short in such account(s), to cancel any open orders and to close any or all outstanding contracts, all without demand for margin or additional margin, other notice or sale or purchase, or other notice of advertisement. Any such sales or purchases may be made at your discretion on any exchange or other market where such business is usually transacted, or at public auction or private sale, and you may be the purchasers for your own account. It is understood a prior demand, or call, or prior notice of the time and place of such sale or purchase shall not be considered a waiver of your right to sell or buy without demand or notice as herein provided. You shall not be liable to me in any way for any adverse tax consequences resulting from the liquidation of any appreciated Property in any account.
