The Purchaser reserves the right (but shall not be obligated), in its sole discretion and for any reason, to waive any or all of such conditions.

-5-

WITHDRAWAL
WHEN TO WITHDRAW	You can withdraw previously tendered Shares at any time until the Expiration Date and, if the Purchaser has not agreed to accept your Shares for payment by January 15, 2009, you can withdraw them at any time after such time until the Purchaser accepts your Shares for payment.
HOW TO WITHDRAW	To withdraw Shares, you must deliver, by certified mail, a written, notarized notice of withdrawal with the required information to the Purchaser while you still have the right to withdraw the Shares.  A withdrawal will be effective upon delivery. Any notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn and must be signed by the person(s) who signed the Letter of Transmittal in the same manner as the Letter of Transmittal was signed, and must be notarized by a duly licensed notary public. Any Shares properly withdrawn will be deemed not to be validly tendered for purposes of the Offer. Withdrawn Shares may be re-tendered prior to the Expiration Date.
PAYMENT
PAYMENT	Upon the expiration of the Offer and the acceptance of the Shares you tender, the Purchaser will pay you (either directly, or indirectly through the Corporation’s transfer agent) promptly (within three business days, to the extent possible) upon the confirmation from the Corporation that the Shares will be transferred to the Purchaser.  Confirmation will generally occurs approximately 10 days after the transfer agent’s receipt of the documentation described in the instructions provided with the Letter of Transmittal.
MARKET VALUE OF THE SHARES AND DETERMINATION OF OFFER PRICE
MARKET VALUE OF THE SHARES	The Shares do not have a readily ascertainable market value because there is no established market available for buying and selling your Shares.  There is no public market for the Shares except a limited informal secondary market and limited trading on the “Pink Sheets,” and neither the Shareholders nor the Purchasers have any accurate means for determining the actual present value of the Shares. The Corporation heeds: “[a]s our stock is currently not listed on a national exchange, there is no established public trading market for our stock. Consequently, there is the risk that you may not be able to sell our stock at a time or price acceptable to you.” (Annual Report on Form 10-K filed March 26, 2008). Although there can be no certainty as to the actual present value of the Shares, the Corporation has estimated that the Corporation could have an estimated net asset value of approximately $7.40 per Share as of December 31, 2008.  (See Annual Report on Form 10-K filed with the Commission on March 13, 2009.)  There can be no assurance as to the timing or amount of any future Corporation dividends, and there cannot be any assurance that the Corporation’s estimate accurately reflects an approximate value of the Shares or that the actual amounts that may be realized by holders for the Shares may not vary substantially from this estimate. The Purchaser believes that real estate values have declined since the Corporation estimated its net asset value at $7.40 per Share. As such, the Purchaser anticipates that the Corporation’s next valuation of its net asset value will be lower than $7.40 per Share.

DETERMINATION OF OFFER PRICE	The Purchasers are making the Offer for investment purposes and with the intention of making a profit from the ownership of the Shares.  In establishing the purchase price of $4.60 per Share, the Purchasers are motivated to establish the lowest price which might be acceptable to Shareholders consistent with the Purchasers’ objectives.  In determining the Offer Price, the Purchaser analyzed a number of quantitative and qualitative factors, including: (i) the lack of a formalized market for resale of the Shares and the resulting lack of liquidity of an investment in the Corporation; (ii) the Purchaser’s internal estimation of value of the Corporation’s real estate assets utilizing valuation methodologies customarily employed by independent appraisers such as the discounted cash flow analysis, direct capitalization analysis, mark-to-market analysis, and comparable sales analysis; (iii) recent material events publicly reported by the Corporation, (iv) the offer price offered by other bidders, and (v) the projected expenses to be incurred by the Purchaser in connection with the Offer.
MISCELLANEOUS
DISPUTE RESOLUTION	By tendering your Shares, you will be agreeing to arbitrate any disputes that may arise between you and the Purchaser, to subject yourself to personal jurisdiction in California, and that the prevailing party in any such action will be entitled to recover attorneys’ fees and costs.
CORPORATION’S RECOMMENDATION	The Purchaser has not sought the approval or disapproval of the Corporation. If the Corporation is aware of the Offer, the Corporation is required to make a recommendation to the security holders within 10 business days of the earlier of the commencement of the Offer or the date on which the Corporation becomes aware of the Offer.
IMPACT ON NON TENDERING SHAREHOLDERS	The Purchaser does not anticipate that Shares held by non-tendering Shareholders will be affected by the Offer.

PURCHASER’S FUTURE INTENTIONS CONCERNING THE CORPORATION The Purchaser is seeking to purchase a total of 100,000 Shares. If the Purchaser acquires fewer than 100,000 Shares pursuant to the Offer, the Purchaser may seek to make further purchases on the open market at prevailing prices, or solicit Shares pursuant to one or more future tender offers at the same price, a higher price or a lower price. Alternatively, the Purchaser may discontinue any further purchases of Shares after termination of the Offer, regardless of the number of Shares purchased.   The Offer is not made with any current view toward or plan or purpose of acquiring Shares in a series of successive and periodic offers.  The Purchaser currently has no plans or proposals regarding future tender offers with respect to the Shares.  Additionally, the Purchaser has no present intention to seek control of the Corporation or to change the management or operations of the Corporation.   The Purchaser reserves the right to gauge the response to this solicitation, and may consider future offers. Factors affecting the Purchaser’s future interest in acquiring additional Shares include, but are not limited to, the relative success of the current Offer, any increase or decrease in the availability of capital for investment by the Purchaser and its investment fund affiliates, the current diversification and performance of each affiliated fund’s portfolio of real estate interests, the development of any public market in the Shares or actions by unrelated parties to tender for or purchase Shares, the status of and changes and trends in the Corporation’s operations, announcement of pending property sales and the proposed terms of sales, and local and national real estate and financial market developments and trends.

DEPOSITARY

The Purchaser is acting as the depositary. No independent party will hold tendered Shares until the Offer closes and payment is made. Because there is no independent intermediary to hold the Purchaser’s funds and the tendered Shares, the Purchaser may have access to the Shares before all conditions to the Offer have been satisfied and selling Shareholders have been paid; however, the Purchaser has no rights with respect to the Shares prior to the Expiration Date and acceptance by the Purchaser for payment.

To whom it may concern:

The undersigned hereby tenders to Opportunity Investment Fund I, LLC(the “Purchaser”) all of the shares of common stock (“Shares”) in the Corporation held by the undersigned as set forth above (or, if less than all such Shares, the number set forth in BOX A below), at a purchase price equal to $4.60 per Share in cash, subject to the conditions set forth in the Offer to Purchase, dated November 16, 2009 (the “Offer to Purchase”) and in this Letter of Transmittal, as each may be supplemented or amended from time to time (which together constitute the “Offer”).

Receipt of the Offer to Purchase is hereby acknowledged. The undersigned recognizes that, if more than 100,000 Shares are validly tendered prior to or on the Expiration Date and not properly withdrawn, the Purchaser will, upon the terms of the Offer, accept for payment from among those Shares tendered prior to or on the Expiration Date, 100,000 Shares on a first-come first-served basis based upon the number of Shares validly tendered prior to the Expiration Date and not withdrawn.

Subject to and effective upon acceptance for payment of any of the Shares tendered hereby, the undersigned hereby sells, assigns, and transfers to Purchaser all right, title, and interest in and to such Shares that are purchased pursuant to the Offer. The undersigned hereby irrevocably constitutes and appoints the Purchaser as the true and lawful agent and attorney-in-fact and proxy of the undersigned with respect to such Shares, with full power of substitution (such power of attorney and proxy being deemed to be an irrevocable power and proxy coupled with an interest), to deliver such Shares and transfer ownership of such Shares, on the books of the Corporation, together with all accompanying evidences of transfer and authenticity, to the Purchaser and, upon acceptance of the tender of such Shares by the Purchaser, to exercise all voting rights and to receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares all in accordance with the terms of the Offer. Upon the purchase of Shares pursuant to the Offer, all prior proxies and consents given by the undersigned with respect to such Shares will be revoked and no subsequent proxies or consents may be given (and if given will not be deemed effective). In addition, by executing this Letter of Transmittal, the undersigned assigns to the Purchaser all of the undersigned’s rights to receive dividends from the Corporation with respect to Shares which are purchased pursuant to the Offer, other than dividends declared or paid through the Expiration Date, and all proceeds that are paid on or after the Expiration Date from or as a result of any claim, litigation, class or derivative action brought by or for the benefit of the shareholders with respect to the transferred Shares, regardless of when the claims brought pursuant to such action accrued. Upon request, the Seller will execute and deliver, and irrevocably directs any custodian to execute and deliver, any additional documents deemed by the Purchaser to be necessary or desirable to complete the assignment, transfer, and purchase of such Shares. The Purchaser reserves the right to transfer or assign to one or more of the Purchaser’s affiliates, in whole or from time to time in part, the right to purchase all or any portion of the Shares tendered in the Offer, but any such transfer or assignment will not relieve the Purchaser of its obligations under the Offer or prejudice the rights of tendering shareholders to receive payment for Shares validly tendered and accepted for payment pursuant to the Offer.

The undersigned hereby represents and warrants that the undersigned owns the Shares tendered hereby and has full power and authority to validly tender, sell, assign, and transfer the Shares tendered hereby, and that when any such Shares are purchased by the Purchaser, the Purchaser will acquire good, marketable, and unencumbered title thereto, free and clear of all liens, restrictions, charges, encumbrances, conditional sales agreements, or other obligations relating to the sale or transfer thereof, and such Shares will not be subject to any adverse claim. The undersigned understands that a tender of Shares to the Purchaser will constitute a binding agreement between the undersigned and the Purchaser upon the terms and subject to the conditions of the Offer. The undersigned recognizes the right of the Purchaser to effect a change of dividend address to 3501 Jamboree Road, Suite 500, Newport Beach, CA 92660. The undersigned recognizes that under certain circumstances set forth in the Offer to Purchase, the Purchaser may not be required to accept for payment any of the Shares tendered hereby. In such event, the undersigned understands that any Letter of Transmittal for Shares not accepted for payment will be destroyed by the Purchaser. All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable.

2

The undersigned acknowledges that: (i) the Shares may be transferred only by the record owner in person or by its duly authorized agent or attorney upon completion of all forms obtained from the Company duly executed, delivery of the forms and such other documents as the Company may require to the Company, and payment in full for the Shares and any applicable transfer tax, (ii) the transfer of Shares is subject to all the limitations and restrictions contained in the Company’s Second Articles of Amendment and Restatement, as amended (the “Charter”), and Bylaws, as amended (together with the Charter, the “Company Documents”), including compliance with applicable state and federal securities and tax laws, (iii) no transfer or assignment of any Shares shall be made if counsel for the Company is of the opinion that such transfer or assignment would be in violation of any state securities or “Blue Sky” laws (including investment suitability standards) applicable to the Company (if this would be the case as a result of this transfer, the Company will return this form and advise you of the reason that the transfer is void), (iv) the transfer of the Shares is not effective until registration of the transfer on the books of the Company, (v) the Shares are subject in all respects to and are governed by the Company Documents and (iv) the interest being retained by the undersigned, if any, must be at least the minimum number of shares of Common Stock required under “Suitability Standards” in the Prospectus unless such transfer is made by gift, inheritance, intra-family transfer, family dissolution, operation of law, or to affiliates.

Rule 14e-4 Representations.  The undersigned further represents and warrants that (i) such Shareholder owns the Shares being tendered within the meaning of Rule 14e-4 under the Exchange Act and (ii) the tender of such Shares complies with Rule 14e-4.

Arbitration Agreement: The Purchaser and the undersigned agree that any dispute, claim, or controversy arising out of a purchase of Shares shall be resolved by submission to binding arbitration in Newport Beach, California before the American Arbitration Association, and all parties agree to be subject to jurisdiction in California. The arbitrator selected must follow applicable Federal securities laws and New York law. The arbitrator’s decision will be final and binding upon the parties. A judgment upon any award may be entered in a court of competent jurisdiction. Each party shall be responsible for advancing one-half of the costs of arbitration; provided that the prevailing party shall be entitled to recover expenses relating to the arbitration, including but not limited to attorneys’ fees, arbitrator fees, and filing fees. Neither party is waiving any rights under the federal securities laws, rules, or regulations. All matters relating to this arbitration shall be governed by the Federal Arbitration Act (9 U.S.C. Sections 1 et seq.).

The undersigned acknowledges that all questions as to the form and validity (including time of receipt) of notices of withdrawal will be determined by the Purchaser, in its sole discretion, which determination shall be final and binding. The undersigned further acknowledges that the Purchaser reserves the absolute right to reject any or all tenders if not in proper form or if the acceptance of, or payment for, the Shares tendered may, in the opinion of the Purchaser’s counsel, be unlawful. The Purchaser also reserves the right to waive any defect or irregularity in any tender with respect to any particular Shares of any particular Shareholder, and the Purchaser’s interpretation of the terms and conditions of the Offer (including this Letter of Transmittal and the Instructions hereto) will be final and binding. The undersigned acknowledges that neither the Purchaser nor any other person will be under any duty to give notification of any defects or irregularities in the tender of any Shares or will incur any liability for failure to give any such notification.
