3.     EXCLUSIONS FROM COLLATERAL. Bank may, at its sole discretion and at any time upon written notice to Debtor, release Bank's security interest in any WF Securities in the Collateral or Proceeds and exclude WF Securities from the determination of value requirements to which the Collateral is subject under this Agreement.

4.1     Value Requirements. The Margin Value of the Collateral shall at all times exceed the outstanding balance of Indebtedness. Collateral subject to the provisions of Section 11(d) (1) of the Securities Exchange Act of 1934 may

not be used to satisfy value requirements unless and until they have been owned by Debtor for a period greater than thirty (30) days. Whenever applicable, the credit limits of Regulation U of the Federal Reserve Board (12 U.S.C. § 221 et seq) shall also be satisfied as prescribed therein. Collateral satisfying value requirements in this Agreement cannot also satisfy other value requirements in favor of Bank, if any.

4.2     Maintenance of Value. Whenever value requirements in this Agreement are not met Debtor shall, within three (3) business days, take all remedial action necessary to restore the required value. Remedial action may include the following in any combination or amount: (a) delivery of additional Collateral acceptable to Bank; (b) substitution of assets providing little or no support to value requirements for assets providing greater support; (c) payoff of the Indebtedness (or if applicable, reduction thereof); or (d) conversion of assets to cash. Bank has no duty to act to: (a) prevent any decline in market value of Collateral or Proceeds; (b) preserve any Debtor rights against prior parties relating to Collateral or Proceeds; or (c) assure that Proceeds of any Collateral are deposited into interest bearing account(s).

4.3     Breach of Value Requirements. Bank is not obligated to permit an advance when value requirements are not met or if permitted would not then be met. Failure to timely meet value requirements is an Event of Default, and allows Bank, in its sole option, to accelerate the Indebtedness and exercise its rights and remedies under this Agreement.

4.4     Excess Collateral. Unless an Event of Default occurs, Collateral in excess of the value requirements is available for withdrawal at Debtor's request to Bank, free and clear of its lien. Debtor will provide reasonable time, information and cooperation for Debtor withdrawal requests. No Intermediary is authorized to release Collateral, or allow excess Collateral withdrawals, without written consent of an authorized employee of Bank's applicable credit department.

4.5     Trading of Collateral Permitted. Unless j:)n Event of Default occurs, and provided all value requirements would continue to be met, Debtor, or any party authorized by Debtor to act with respect to the Collateral, may receive payments of interest and/or cash dividends earned on the Collateral in the Securities Account, and may trade Collateral in the Securities Account. Except as provided in this Agreement, Bank is not obligated to permit any withdrawal or distribution of Collateral or Proceeds,

4.6     Rule 144/145 Collateral. For so long as any of the Collateral may be subject to Securities Exchange Commission ("SEC") Rule 144 or Rule 145, Debtor will not sell or otherwise transfer shares of securities of the issuer of such Collateral (whether or not such shares are Collateral) without Bank's prior written consent, which consent shall be given in Bank's sole discretion.

4.7     Hedge Fund Collateral . Hedge fund interests credited, maintained or recorded in the Securities Account (each and collectively a "Hedge Fund") are Collateral under this Agreement even if the issuer's books and records may not reflect Bank's lien and even if Bank has not agreed the Hedge Fund contributes to value requirements in this Agreement.
