| Credit Line Agreement |
|-----------------------|

| A | The Borrower has received and read a copy of this Borrower Agreement, the attached Credit Line Account Application and Agreement (including the Credit Line Agreement following this Borrower Agreement) and the Loan Disclosure Statement explaining the risk factors that the Borrower should consider before obtaining a loan secured by the Borrower’s securities account.

|---|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

| B | THE BORROWER UNDERSTANDS AND AGREES THAT UBS BANK USA MAY DEMAND FULL OR PARTIAL PAYMENT OF THE CREDIT LINE OBLIGATIONS, AT ITS SOLE OPTION AND WITHOUT CAUSE, AT ANY TIME, AND THAT NEITHER FIXED RATE ADVANCES NOR VARIABLE RATE ADVANCES ARE EXTENDED FOR ANY SPECIFIC TERM OR DURATION. THE BORROWER UNDERSTANDS AND AGREES THAT ALL ADVANCES ARE SUBJECT TO COLLATERAL MAINTENANCE REQUIREMENTS. THE BORROWER UNDERSTANDS THAT UBS BANK USA MAY, AT ANY TIME, IN ITS DISCRETION, TERMINATE AND CANCEL THE CREDIT LINE REGARDLESS OF WHETHER OR NOT AN EVENT HAS OCCURRED. |

|   |   |
|--------|--------|

| C | UNLESS DISCLOSED IN WRITING TO UBS BANK USA AT THE TIME OF THIS AGREEMENT, AND APPROVED BY UBS BANK USA, THE BORROWER AGREES NOT TO USE THE PROCEEDS OF ANY ADVANCE EITHER TO PURCHASE, CARRY OR TRADE IN SECURITIES OR TO REPAY ANY DEBT (I) USED TO PURCHASE, CARRY OR TRADE IN SECURITIES OR (II) TO ANY AFFILIATE OF UBS BANK USA. THE BORROWER WILL BE DEEMED TO REPEAT THIS AGREEMENT EACH TIME THE BORROWER REQUESTS AN ADVANCE. |
|---|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

| D | THE BORROWER UNDERSTANDS THAT BORROWING USING SECURITIES AS COLLATERAL ENTAILS RISKS. SHOULD THE VALUE OF THE SECURITIES IN THE COLLATERAL ACCOUNT DECLINE BELOW THE REQUIRED COLLATERAL MAINTENANCE REQUIREMENTS, UBS BANK USA MAY REQUIRE THAT THE BORROWER POST ADDITIONAL COLLATERAL, REPAY PART OR ALL OF THE BORROWER’S LOAN AND/OR SELL THE BORROWER’S SECURITIES. ANY REQUIRED LIQUIDATIONS MAY INTERRUPT THE BORROWER’S LONG-TERM INVESTMENT STRATEGIES AND MAY RESULT IN ADVERSE TAX CONSEQUENCES. |
|---|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

| E | Neither UBS Bank USA nor UBS Financial Services Inc. provides legal or tax advice. |
|---|------------------------------------------------------------------------------------|

| F | Upon execution of this Credit Line Account Application and Agreement, the Borrower will have supplied all of the information requested in the Application and the Borrower declares it as true and accurate and further agrees to promptly notify UBS Bank USA in writing of any material changes to any or all of the information contained in the Application including information relating to the Borrower’s financial situation. |

|   |   |
|--------|--------|

| G | Subject to any applicable financial privacy laws and regulations, data regarding the Borrower and the Borrower’s securities accounts may be shared with UBS Bank USA affiliates. Subject to any applicable financial privacy laws and regulations, the Borrower requests that UBS Bank USA share such personal financial data with non-affiliates of UBS Bank USA as is necessary or advisable to effect, administer or enforce, or to service, process or maintain, all transactions and accounts contemplated by this Agreement. |
|---|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

| H | The Borrower authorizes UBS Bank USA and UBS Financial Services Inc. to obtain a credit report or other credit references concerning the Borrower (including making verbal or written inquiries concerning credit history) or to otherwise verify or update credit information given to UBS Bank USA at any time. The Borrower authorizes the release of this credit report or other credit information to UBS Bank USA affiliates as it deems necessary or advisable to effect, administer or enforce, or to service, process or maintain all transactions and accounts contemplated by this Agreement, and for the purpose of offering additional products, from time to time, to the Borrower. The Borrower authorizes UBS Bank USA to exchange Borrower information with any party it reasonably believes is conducting a legitimate credit inquiry in accordance with the Fair Credit Reporting Act. UBS Bank USA may also share credit or other transactional experience with the Borrower’s designated UBS Financial Services Inc. Financial Advisor or other parties designated by the Borrower. |
|---|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| I | UBS Bank USA is subject to examination by various federal, state and self-regulatory organizations and that books and records maintained by UBS Bank USA are subject to inspection and subpoena by these regulators and by federal, state, and local law enforcement officials. The Borrower also acknowledges that such regulators and officials may, pursuant to treaty or other arrangements, in turn disclose such information to the officials or regulators of other countries, and that U.S. courts may be required to compel UBS Bank USA to disclose such information to the officials or regulators of other countries. The Borrower agrees that UBS Bank USA may disclose to such regulators and officials information about the Borrower and transactions in the credit line account or other accounts at UBS Bank USA without notice to the Borrower. In addition, UBS Bank USA may in the context of a private dispute be required by subpoena or other judicial process to disclose information or produce documentation related to the Borrower, the credit line account or other accounts at UBS Bank USA. The Borrower acknowledges and agrees that UBS Bank USA reserves the right, in its sole discretion, to respond to subpoenas and judicial process as it deems appropriate. |
|---|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| J | To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. When the Borrower opens an account with UBS Bank USA, UBS Bank USA will ask for the Borrower’s name, address, and other information that will allow UBS Bank USA to identify the Borrower. UBS Bank USA may also ask to see other identifying documents. UBS Financial Services Inc. and UBS Bank USA are firmly committed to compliance with all applicable laws, rules and regulations, including those related to combating money laundering. The Borrower understands and agrees that the Borrower must take all necessary steps to comply with the anti-money laundering laws, rules and regulations of the Borrower’s country of origin, country of residence and the sites of the Borrower’s transaction. |

| K | UBS Bank USA and its affiliates will act as creditors and, accordingly, their interests may be inconsistent with, and potentially adverse to, the Borrower’s interests. As a lender and consistent with normal lending practice, UBS Bank USA may take any steps necessary to perfect its interest in the Credit Line, issue a call for additional collateral or force the sale of the Borrower’s securities if the Borrower’s actions or inactions call the Borrower’s creditworthiness into question. Neither UBS Bank USA nor UBS Financial Services Inc. will act as Client’s investment advisor with respect to any liquidation. In fact UBS Bank USA will act as a creditor and UBS Financial Services Inc. will act as a securities intermediary. |
|---|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| L | The Borrower understands that, if the Collateral Account is a managed account with UBS Financial Services Inc., (i) in addition to any fees payable to UBS Financial Services Inc. in connection with the Borrower’s managed account, interest will be payable to the Bank on an amount advanced to the Borrower in connection with the Credit Line Account, and (ii) the performance of the managed account might not exceed the managed account fees and the interest expense payable to the Bank in which case the Borrower’s overall rate of return will be less than the costs associated with the managed account. |

|   |   |
|--------|--------|

| M | UBS Bank USA may provide copies of all credit line account statements to UBS Financial Services Inc. and to any Guarantor. The Borrower acknowledges and agrees that UBS Bank USA may share any and all information regarding the Borrower and the Borrower’s accounts at UBS Bank USA with UBS Financial Services Inc. UBS Financial Services Inc. may provide copies of all statements and confirmations concerning each Collateral Account to UBS Bank USA at such times and in such manner as UBS Bank USA may request and may share with UBS Bank USA any and all information regarding the Borrower and the Borrower’s accounts with UBS Financial Services Inc. |

|--------|----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | c) | UNLESS DISCLOSED IN WRITING TO THE BANK AT THE TIME OF THE APPLICATION, AND APPROVED BY THE BANK, THE BORROWER AGREES NOT TO USE THE PROCEEDS OF ANY ADVANCE EITHER TO PURCHASE, CARRY OR TRADE IN SECURITIES OR TO REPAY ANY DEBT (I) USED TO PURCHASE, CARRY OR TRADE IN SECURITIES OR (II) TO ANY AFFILIATE OF THE BANK. THE BORROWER WILL BE DEEMED TO REPEAT THE AGREEMENT IN THIS SECTION 2(C) EACH TIME IT REQUESTS AN ADVANCE. |
|--------|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | d) | Prior to the first Advance under the Credit Line, the Borrower must sign and deliver to the Bank a Federal Reserve Form U-1 and all other documentation as the Bank may require.

|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | e) | The Borrower consents and agrees that, in connection with establishing the Credit Line Account, approving any Advances to the Borrower or for any other purpose associated with the Credit Line, the Bank may obtain a consumer or other credit report from a credit reporting agency relating to the Borrower’s credit history.

|--------|--------|

|   | f) | The Borrower understands that the Bank will, directly or indirectly, pay a portion of the interest that it receives to the Borrower’s financial advisor at UBS Financial Services Inc. or one of its affiliates. To the extent permitted by applicable law, the Bank may also charge the Borrower fees for establishing and servicing the Credit Line Account. |
|--------|----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | g) | Following each month in which there is activity in the Borrower’s Credit Line Account in amounts greater than $1, the Borrower will receive an account statement showing the new balance, the amount of any new Advances, year to date interest charges, payments and other charges and credits that have been registered or posted to the Credit Line Account. |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | h) | Each of the Loan Parties understands and agrees that the Bank may, at any time, in its discretion, terminate and cancel the Credit Line regardless of whether or not an Event has occurred. In the event the Bank terminates and cancels the Credit Line the Credit Line Obligations shall be immediately due and payable in full. If the Credit Line Obligations are not paid in full, the Bank shall have the right, at its option, to exercise any or all of its remedies described in Section 10 of this Agreement. |
|--------|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 3) | Terms of Advances |
|----|-------------------|

|   | a) | Advances made under this Agreement will be available to the Borrower in the form, and pursuant to procedures, as are established from time to time by the Bank in its sole and absolute discretion. The Borrower and each Loan Party agree to promptly provide all documents, financial or other information in connection with any Advance as the Bank may request. Advances will be made by wire transfer of funds to an account as specified in writing by the Borrower or by any other method agreed upon by the Bank and the Borrower. The Borrower acknowledges and agrees that the Bank will not make any Advance to the Borrower unless the collateral maintenance requirements that are established by the Bank in its sole and absolute discretion have been satisfied. |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | b) | Each Advance made under a Premier Credit Line will be a Variable Rate Advance unless otherwise designated as a Fixed Rate Advance in an Advance Advice sent by the Bank to the Borrower. The Bank will not designate any Advance as a Fixed Rate Advance unless it has been requested to do so by the Borrower (acting directly or indirectly through the Borrower’s UBS Financial Services Inc. financial advisor or other agent designated by the Borrower and acceptable to the Bank). Each Advance Advice will be conclusive and binding upon the Borrower, absent manifest error, unless the Borrower otherwise notifies the Bank in writing no later than the close of business, New York time, on the third Business Day after the Advance Advice is received by the Borrower. |
|--------|----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | c) | Each Advance made under a Prime Credit Line will be a Variable Advance. |

|   | d) | Unless otherwise agreed by the Bank: (i) all Fixed Rate Advances must be in an amount of at least $100,000; and (ii) all Variable Rate Advances must be in an amount of at least $2,500. If the Borrower is a natural person, the initial Variable Rate Advance under the Credit Line must be in an amount equal to at least $25,001 (the “Initial Advance Requirement”). If the initial Advance requested by the Borrower is made in the form of a check drawn on the Credit Line that does not satisfy the Initial Advance Requirement, then, in addition to and not in limitation of the Bank’s rights, remedies, powers or privileges under this Agreement or applicable law, the Bank may, in its sole and absolute discretion: |
|--------|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | (i) | pay the check drawn by the Borrower if, prior to paying that check, the Bank makes another Advance to the Borrower, which Advance shall be in an amount not less than $25,001; or |
|--------|-----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | (ii) | pay the check drawn by the Borrower; or |
|--------|------|-----------------------------------------|

|   |   |
|--------|--------|

|   | (iii) | decline to pay (bounce) the check. |
|--------|-------|------------------------------------|

|   |   |
|--------|--------|

| 4) | Interest |
|----|----------|

|   | a) | Each Fixed Rate Advance will bear interest at a fixed rate for the Interest Period specified in the related Advance Advice. The rate of interest payable on each Fixed Rate Advance will be determined by adding a percentage rate to LIBOR as of the date that the fixed rate is determined. |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | b) | Each Variable Rate Advance under a Premier Credit Line will bear interest at a variable rate equal to LIBOR, adjusted daily, plus the percentage rate that (unless otherwise specified by the Bank in writing) is shown on Schedule I below for the Approved Amount of the Credit Line. For Premier Credit Lines, the rate of interest payable on Variable Rate Advances is subject to change without notice in accordance with fluctuations in LIBOR and in the Approved Amount. On each day that LIBOR changes or the Approved Amount crosses one of the thresholds that is indicated on Schedule I (or that is otherwise specified by the Bank in writing), the interest rate on all Variable Rate Advances will change accordingly. |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | c) | Each Variable Rate Advance under a Prime Credit Line will bear interest at a variable rate equal to the Prime Rate, adjusted daily, plus the percentage rate that (unless otherwise specified by the Bank in writing) is shown on the attached Schedule II and that corresponds to the aggregate principal amount outstanding under the Prime Credit Line on that day. For Prime Credit Lines, the rate of interest payable on Variable Rate Advances is subject to change without notice in accordance with fluctuations in the Prime Rate and in the aggregate amount outstanding under the Prime Credit Line. On each date that the Prime Rate changes or the aggregate principal amount outstanding under the Prime Credit Line crosses one of the thresholds that is indicated on Schedule II (or that is otherwise specified by the Bank in writing), the interest rate on all Variable Rate Advances will change accordingly. |
|--------|----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

----

| 5) | Payments |
|----|----------|

|   | a) | Each Fixed Rate Advance will be due and payable in full ON DEMAND or, if not earlier demanded by the Bank, on the last day of the applicable Interest Period. Any Fixed Rate Advance as to which the Bank has not made a demand for payment and that is not paid in full or renewed, which renewal is in the sole and absolute discretion of the Bank, (pursuant to procedures as may be established by the Bank) as another Fixed Rate Advance on or before the last day of its Interest Period, will be automatically renewed on that date as a U.S. dollar denominated, Variable Rate Advance in an amount (based, in the case of any conversion of a non-U.S. dollar denominated Fixed Rate Advance, upon the applicable, spot currency exchange rate as of the maturity date, as determined by the Bank) equal to the unpaid principal balance of the Fixed Rate Advance plus any accrued but unpaid interest on the Fixed Rate Advance, which Variable Rate Advance will then accrue additional interest at a variable rate as provided in this Agreement. |
|--------|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | c) | The Borrower promises to pay the outstanding principal amount of each Advance, together with all accrued but unpaid interest on each Advance, any and all fees or other charges payable in connection with each Advance, on the date the principal amount becomes due (whether by reason of demand, the occurrence of a stated maturity date, by reason of acceleration or otherwise). The Borrower further promises to pay interest in respect of the unpaid principal balance of each Advance from the date the Advance is made until it is paid in full. All interest will be computed on the basis of the number of days elapsed and a 360-day year. Interest on each Advance will be payable in arrears as follows: |
|--------|----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | (i) | for Fixed Rate Advances - on the last day of the Interest Period (or if the Interest Period is longer than three months, on the last day of each three month period following the date of the Advance) and on each date that all or any portion of the principal amount of the Fixed Rate Advance becomes due or is paid; and |
|--------|-----|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | (ii) | for Variable Rate Advances - on the twenty-second day of each month other than December, and on the thirty-first day of December, and on each date that all or any portion of the principal amount of the Variable Rate Advance becomes due or is paid. |
|--------|------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | d) | All payments of principal, interest or other amounts payable under this Agreement will be made in immediately available funds and in the same currency in which the Advance was made, which unless otherwise agreed by the Bank, will be U.S. dollars. UBS Financial Services Inc. or UBS International Inc., as applicable, may act as collecting and servicing agent for the Bank for the Advances. All payments will be made by wire transfer of funds to an account specified by the Bank or by another method agreed upon by the Bank and the Borrower. Upon receipt of all payments, the Bank will credit the same to the Credit Line Account. The Bank shall apply the proceeds of any payments in the following order; first to any Breakage Costs, Breakage Fee, other fees, costs of collection and expenses, second to accrued interest and third to the outstanding principal amount of the related Advance. |
|--------|----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | e) | All payments must be made to the Bank free and clear of any and all present and future taxes (including withholding taxes), levies, imposts, duties, deductions, fees, liabilities and similar charges other than those imposed on the overall net income of the Bank. If so requested by the Bank, the Borrower will deliver to the Bank the original or a certified copy of each receipt evidencing payment of any taxes or, if no taxes are payable in respect of any payment under this Agreement, a certificate from each appropriate taxing authority, or an opinion of counsel in form and substance and from counsel acceptable to the Bank in its sole and absolute discretion, in either case stating that the payment is exempt from or not subject to taxes. If any taxes or other charges are required to be withheld or deducted from any amount payable by the Borrower under this Agreement, the amount payable will be increased to the amount which, after deduction from the increased amount of all taxes and other charges required to be withheld or deducted from the amount payable, will yield to the Bank the amount stated to be payable under this Agreement. If any of the taxes or charges are paid by the Bank, the Borrower will reimburse the Bank on demand for the payments, together with all interest and penalties that may be imposed by any governmental agency. None of the Bank, UBS Financial Services Inc., UBS-I or their respective employees has provided or will provide legal advice to the Borrower or any Loan Party regarding compliance with (or the implications of the Credit Line and the related guaranties and pledges under) the laws (including tax laws) of the jurisdiction of the Borrower or any Loan Party or any other jurisdiction. The Borrower and each Loan Party are and shall be solely responsible for, and the Bank shall have no responsibility for, the compliance by the Loan Parties with any and all reporting and other requirements arising under any applicable laws. |
|--------|----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | f) | In no event will the total interest and fees, if any, charged under this Agreement exceed the maximum interest rate or total fees permitted by law. In the event any excess interest or fees are collected, the same will be refunded or credited to the Borrower. If the amount of interest payable by the Borrower for any period is reduced pursuant to this Section 5(f), the amount of interest payable for each succeeding period will be increased to the maximum rate permitted by law until the amount of the reduction has been received by the Bank. |
|--------|----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 6) | Prepayments; Breakage Charges |

|--------|----|-----------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | b) | The Borrower may repay any Fixed Rate Advance, in whole or in part. The Borrower agrees to reimburse the Bank, immediately upon demand, for any loss or cost (“Breakage Costs”) that the Bank notifies the Borrower has been incurred by the Bank as a result of (i) any payment of the principal of a Fixed Rate Advance before the expiration of the Interest Period for the Fixed Rate Advance (whether voluntarily, as a result of acceleration, demand or otherwise), or (ii) the Customer’s failure to take any Fixed Rate Advance on the date agreed upon, including any loss or cost (including loss of profit or margin) connected with the Bank’s re-employment of the amount so prepaid or of those funds acquired by the Bank to fund the Advance not taken on the agreed upon date. |

| 7) | Joint Credit Line Account Agreement; Suspension and Cancellation |
|----|------------------------------------------------------------------|

|   | a) | If more than one Person is signing this Agreement as the “Borrower”, each party (a “Joint Borrower”) will be jointly and severally liable for the Credit Line Obligations, regardless of any change in business relations, divorce, legal separation, or other legal proceedings or in any agreement that may affect liabilities between the parties. Except as provided below for the reinstatement of a suspended or cancelled Credit Line, and unless otherwise agreed by the Bank in writing, the Bank may rely on, and each Joint Borrower will be responsible for, requests for Advances, directions, instructions and other information provided to the Bank by any Joint Borrower. |
|--------|----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|--------|--------|

|   | b) | Any Joint Borrower may request the Bank to suspend or cancel the Credit Line by sending the Bank a written notice of the request addressed to the Bank at the address shown on the Borrower’s periodic Credit Line Account statements. Any notice will become effective three Business Days after the date that the Bank receives it, and each Joint Borrower will continue to be responsible for paying: (i) the Credit Line Obligations as of the effective date of the notice, and (ii) all Advances that any Joint Borrower has requested but that have not yet become part of the Credit Line Obligations as of the effective date of the notice. No notice will release or in any other way affect the Bank’s interest in the Collateral. All subsequent requests to reinstate credit privileges must be signed by all Joint Borrowers comprising the Borrower, including the Joint Borrower requesting the suspension of credit privileges. Any reinstatement will be granted or denied in the sole and absolute discretion of the Bank. |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | c) | All Credit Line Obligations will become immediately due and payable in full as of the effective date of any suspension or cancellation of the Credit Line. The borrower will be responsible for the payment of all charges incurred on the Advances after the effective date. The Bank will not release any Loan Party from any of the obligations under this Agreement or any related agreement until the Credit Line Obligations have been paid in full and this Agreement has been terminated. |

|--------|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | b) | The Borrower and if applicable, any Pledgor on the Collateral Account, will take all actions reasonably requested by the Bank to evidence, maintain and perfect the Bank’s first priority security interest in, and to enable the Bank to obtain control over, the Collateral and any additional collateral pledged by the Pledgors, including but not limited to making, executing, recording and delivering to the Bank financing statements and amendments thereto, control agreements, notices, assignments, listings, powers, consents and other documents regarding the Collateral and the Bank’s security interest in the Collateral in a form as the Bank reasonably may require. Each Loan Party irrevocably authorizes and appoints each of the Bank and UBS Financial Services Inc., as collateral agent, to act as their agent and attorney-in-fact to file any documents or to execute any documents in their name, with or without designation of authority. Each Loan Party acknowledges that it will be obligated in respect of the documentation as if it had executed the documentation itself. |
|--------|----|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | d) | The Bank’s sole duty for the custody, safe keeping and physical preservation of any Collateral in its possession will be to deal with the Collateral in the same manner as the Bank deals with similar property for its own account. The Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees that the Bank will have no responsibility to act on any notice of corporate actions or events provided to holders of securities or other investment property included in the Collateral. The Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees to (i) notify the Bank promptly upon receipt of any communication to holders of the investment property disclosing or proposing any stock split, stock dividend, extraordinary cash dividend, spin-off or other corporate action or event as a result of which the Borrower or Pledgor would receive securities, cash (other than ordinary cash dividends) or other assets in respect of the investment property, and (ii) immediately upon receipt by the Borrower or Pledgor of any of these assets, cause them to be credited to a Collateral Account or deliver them to or as directed by the Bank as additional Collateral. |
|--------|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | e) | The Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees that all principal, interest, dividends, distributions, premiums or other income and other payments received by the Bank or credited to the Collateral Account in respect of any Collateral may be held by the Bank as additional Collateral or applied by the Bank to the Credit Line Obligations. The Bank may create a security interest in any of the Collateral and may, at any time and at its option, transfer any securities or other investment property constituting Collateral to a securities account maintained in its name or cause any Collateral Account to be redesignated or renamed in the name of the Bank. |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | f) | If a Collateral Account has margin features, the margin features will be removed by UBS Financial Services Inc. or UBS-I, as applicable, so long as there is no outstanding margin debit in the Collateral Account. If there is a margin debit in the Collateral Account, such debit must be paid and satisfied in full prior to the acceptance of this Agreement by the Bank. |
|--------|----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

----

|   | g) | If the Collateral Account permits cash withdrawals in the form of check writing, access card charges, bill payment and/or electronic funds transfer services (for example, Resource Management Account®, Business Services Account BSA®, certain Basic Investment Accounts and certain accounts enrolled in UBS Financial Services Inc. Investment Solutions programs), the “Withdrawal Limit” for the Collateral Account, as described in the documentation governing the account will be reduced on an ongoing basis so that the aggregate lending value of the Collateral remaining in the Collateral Account following the withdrawal may not be less than the amount required pursuant to Section 8(c). |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | h) | In addition to the Bank’s security interest, the Bank will at all times have a right to set off any or all of the Credit Line Obligations at or after the time at which they become due, whether upon demand, at a stated maturity date, by acceleration or otherwise, against all securities, cash, deposits or other property in the possession of or at any time in any account maintained with the Bank or any of its affiliates by or for the benefit of the Borrower, whether carried individually or jointly with others. This right is in addition to, and not in limitation of, any right the Bank may have at law or otherwise. |
|--------|----|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   |   |
|--------|--------|

|   | i) | The Bank reserves the right to disapprove any Collateral and to require the Borrower at any time to deposit into the Borrower’s Collateral Account additional Collateral in the amount as the Bank requests or to substitute new or additional Collateral for any Collateral that has previously been deposited in the Collateral Account. |
|--------|----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 9) | Control |
|----|---------|

|   | a) | The Securities Intermediary will comply with entitlement orders originated by the Bank regarding any Collateral Account without further consent from the Borrower or any Pledgor. The Securities Intermediary will treat all assets credited to a Collateral Account, including money and credit balances, as financial assets for purposes of Article 8 of the Uniform Commercial Code. |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | b) | In order to enable the Borrower and any Pledgor on the applicable Collateral Account to trade financial assets that are from time to time credited to a Collateral Account, the Securities Intermediary may comply with entitlement orders originated by the Borrower or any Pledgor on the applicable Collateral Account (or if so agreed by the Bank, by an investment adviser designated by the Borrower or any Pledgor on the applicable Collateral Account and acceptable to the Bank and the Securities Intermediary) regarding the Collateral Account, but only until the time that the Bank notifies the Securities Intermediary, that the Bank is asserting exclusive control over the Collateral Account. After the Securities Intermediary has received a notice of exclusive control and has had a reasonable opportunity to comply, it will no longer comply with entitlement orders originated by the Borrower or any Pledgor (or by any investment adviser designated by the Borrower or any Pledgor) concerning the Collateral Account. Notwithstanding the foregoing, however, and irrespective of whether it has received any notice of exclusive control, the Securities Intermediary will not comply with any entitlement order originated by the Borrower or any Pledgor (or by any investment adviser designated by the Borrower or any Pledgor) to withdraw any financial assets from a Collateral Account or to pay any money, free credit balance or other amount owing on a Collateral Account (other than cash withdrawals and payments not exceeding the “Withdrawal Limit” as contemplated in Section 8 (g)) without the prior consent of the Bank. |
|--------|----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
