ARTICLE VI.

REMEDIES

SECTION 6.1 Remedies.

(a) Upon the occurrence and during the continuance of any Event of Default, the Secured Party may from time to time exercise in respect of the Pledged Interest, in addition to the other rights and remedies provided for herein or otherwise available to it all the rights and remedies of a secured party on default under the UCC, and the Secured Party may also in its sole discretion, without notice except as specified in Section 6.2 hereof, sell, assign or grant a license to use the Pledged Interest or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of the Secured Party’s offices or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Secured Party may deem commercially reasonable. Notwithstanding the foregoing, other than in the case of an Event of Default under Section 7.01(a)(ii) of the Credit Agreement, Secured Party shall not complete the foreclosure or other Disposition (as defined below) of any property pledged under this Agreement prior to the date that is six months from the date Secured Party first gave notice of such Event of Default to Pledgor. The Secured Party or any of its affiliates may be the purchaser, licensee, assignee or recipient of the Pledged Interest or any part thereof at any such sale and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Pledged Interest sold, assigned or licensed at such sale, to use and apply any of the Secured Obligations owed to the Secured Party as a credit on account of the purchase price of the Pledged Interest or any part thereof payable by the Secured Party at such sale. Each purchaser, assignee, licensee or recipient at any such sale shall acquire the property sold, assigned or licensed absolutely free from any claim or right on the part of the Pledgor, and the Pledgor hereby waives, to the fullest extent permitted by law, all rights of redemption, stay and/or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Secured Party shall not be obligated to make any sale of the Pledged Interest or any part thereof regardless of notice of sale having been given. The Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice,

- 8 -

be made at the time and place to which it was so adjourned. The Pledgor hereby waives, to the fullest extent permitted by law, any claims against the Secured Party arising by reason of the fact that the price at which the Pledged Interest or any part thereof may have been sold, assigned or licensed at such a private sale was less than the price which might have been obtained at a public sale, even if the Secured Party accepts the first offer received and does not offer such Pledged Interest to more than one offeree.

(b) Pledgor acknowledges that the Pledged Interest would, if owned by a purchaser at a foreclosure sale, have a lesser value than if the Pledged Interest were owned by the Pledgor. Secured Party shall have no obligation to obtain the consent of any partner to the limited partnership prior to any sale, assignment, grant of a license to use or other disposition of the Pledged Interest at public or private proceedings (a “Disposition”); provided that any purchaser of such interest will be required to satisfy the conditions of the Partnership Agreement applicable to it, including making certain representations, prior to becoming a limited partner of the partnership. Pledgor agrees that it will endeavor to maximize the value of the Pledged Interest, but acknowledges that Secured Party is under no obligation to so maximize the Pledged Interest value, because, among other things, Secured Party has more limited rights under applicable law than does the Pledgor cost-effectively to enforce certain rights associated with the Pledged Interest.

(i) Pledgor acknowledges that the publication of a notice of sale or similar advertisement in national, regional or local publications is disporportionate to the value of the Collateral and any potential benefit and, therefore, should be regarded as cost prohibitive and, moreover, is unlikely to reach the type of third party buyer interested in purchasing the Pledged Interest. Pledgor further acknowledges and agrees that (i) Secured Party shall have no obligation to publish a notice of sale in any national, regional or local publication except as required by statute and, (ii) should Secured Party notify primary known buyers of timberlands (which shall be deemed to include all timber REITs actually known of by Secured Party, The Campbell Group or any of its affiliates and CalPERS), such notification shall be deemed commercially reasonable. Pledgor also agrees at its own expense promptly to assure delivery of such notice of such sale to everyone known or suspected by Pledgor to have any interest in purchasing such assets. Pledgor acknowledges that Secured Party is not a dealer in the timber property underlying the Pledged Interest. Pledgor, by virtue of Pledgor’s experience in the timber industry, has special information about prospective buyers interested in bidding on the Pledged Interest and the best means to reach such buyers (“Buyer Information”). Pledgor agrees to deliver to Secured Party such Buyer Information promptly upon request by Secured Party and, if Pledgor fails to provide such Buyer Information as requested, shall indemnify and hold harmless Secured Party from any later claims by Pledgor of inadequacy of notice of sale or any related loss, cost, liability or expense on account thereof.

(ii) Pledgor acknowledges and agrees that Secured Party is under no obligation, in the event of a Disposition to a third party, to accept any proceeds other than immediately available funds indefeasibly paid free and clear of all liens, claims and encumbrances. In order to complete a Disposition in a timely manner, Pledgor acknowledges and agrees that Secured Party may purchase the Pledged Interest in a

- 9 -

Disposition and Secured Party may bid any price for the Pledged Interest and set off against the Secured Obligations the amount of such credit bid, up to the amount of the Secured Obligations.

SECTION 6.2 Notice of Sale. The Pledgor acknowledges and agrees that, to the extent notice of sale or other disposition of the Pledged Interest or any part thereof shall be required by law, ten (10) days’ prior notice to the Pledgor of the time and place of any public sale or of the time after which any private sale or other intended disposition is to take place shall be commercially reasonable notification of such matters. No notification need be given to the Pledgor if it has signed, after the occurrence of an Event of Default, a statement renouncing or modifying any right to notification of sale or other intended disposition.

SECTION 6.3 Waiver of Notice and Claims. The Pledgor hereby waives, to the fullest extent permitted by applicable law, notice or judicial hearing in connection with the Secured Party’s taking possession or the Secured Party’s disposition of the Pledged Interest or any part thereof, including any and all prior notice and hearing for any prejudgment remedy or remedies and any such right which the Pledgor would otherwise have under law, and the Pledgor hereby further waives, to the fullest extent permitted by applicable law: (i) all damages occasioned by such taking of possession, (ii) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Secured Party’s rights hereunder and (iii) all rights of redemption, appraisal, valuation, stay, extension or moratorium now or hereafter in force under any applicable law. The Secured Party shall not be liable for any incorrect or improper payment made pursuant to this Article VI in the absence of gross negligence or willful misconduct on the part of the Secured Party. Any sale of, or the grant of options to purchase, or any other realization upon, any Pledged Interest shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the Pledgor therein and thereto, and shall be a perpetual bar both at law and in equity against the Pledgor and against any and all persons claiming or attempting to claim the Pledged Interest so sold, optioned or realized upon, or any part thereof, from, through or under the Pledgor.

SECTION 6.4 Certain Sales of Pledged Interest.

(a) The Pledgor recognizes that, by reason of certain prohibitions contained in law, rules, regulations or orders of any Governmental Authority, the Secured Party may be compelled, with respect to any sale of all or any part of the Pledged Interest, to limit purchasers to those who meet the requirements of such Governmental Authority. The Pledgor acknowledges that any such sales may be at prices and on terms less favorable to the Secured Party than those obtainable through a public sale without such restrictions, and, notwithstanding such circumstances, agrees that any such restricted sale shall be deemed to have been made in a commercially reasonable manner and that, except as may be required by applicable law, the Secured Party shall have no obligation to engage in public sales.

(b) The Pledgor recognizes that, by reason of certain prohibitions contained in the Securities Act, and applicable state securities laws, the Secured Party may be compelled, with respect to any sale of all or any part of the Pledged Interest, to limit purchasers to persons who will agree, among other things, to acquire such Pledged Interest for their own account, for investment and not with a view to the distribution or resale thereof. The Pledgor acknowledges

- 10 -

that any such private sales may be at prices and on terms less favorable to the Secured Party than those obtainable through a public sale without such restrictions (including a public offering made pursuant to a registration statement under the Securities Act), and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner and that the Secured Party shall have no obligation to engage in public sales and no obligation to delay the sale of any Pledged Interest for the period of time necessary to permit the issuer thereof to register it for a form of public sale requiring registration under the Securities Act or under applicable state securities laws, even if such issuer would agree to do so.

SECTION 6.5 No Waiver; Cumulative Remedies.

(a) No failure on the part of the Secured Party to exercise, no course of dealing with respect to, and no delay on the part of the Secured Party in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power, privilege or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power, privilege or remedy; nor shall the Secured Party be required to look first to, enforce or exhaust any other security, collateral or guaranties. All rights and remedies herein provided are cumulative and are not exclusive of any rights or remedies provided by law or otherwise available.

(b) In the event that the Secured Party shall have instituted any proceeding to enforce any right, power, privilege or remedy under this Agreement or any other Loan Document by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Secured Party, then and in every such case, the Pledgor and the Secured Party shall be restored to their respective former positions and rights hereunder with respect to the Pledged Interest, and all rights, remedies, privileges and powers of the Secured Party and the other Secured Parties shall continue as if no such proceeding had been instituted.

SECTION 6.6 No Instructions. The Secured Party agrees that, unless and until an Event of Default has occurred and is continuing under the Credit Agreement, the Secured Party will not give any instructions to the Partnership with respect to the Pledged Interest.

SECTION 7.2 Concerning the Secured Party.

(a) The Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of the Pledged Interest in its possession if such Pledged Interest is accorded treatment substantially equivalent to that which the Secured Party, in its individual capacity, accords its own property consisting of similar instruments or interests, it being understood that the Secured Party shall not have responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Pledged Interest, whether or not the Secured Party has or is deemed to have knowledge of such matters or (ii) taking any necessary steps to preserve rights against any person with respect to any Pledged Interest.
