ADVISORY BOARD ACCELERATES % RENT PAYOUT TIMING

After considerable discussions with your Advisory Board, we have decided to change our distribution method for percentage rents, which have become a progressively more significant part of total revenues. Previously, except for percentage rents, we have maintained a policy of only distributing cash for the actual quarter received. In other words, if Q2 ended June 30, but we received sales proceeds on July 10 (or in Q3), even though Q2 distribution wasn’t made until August 15; we distributed the proceeds on November 15 with the balance of the Q3 distribution.

Our percentage rents are substantially received in Q1 for the prior year, but we have generally paid such rents out evenly over the four subsequent periods to eliminate investor confusion from significant fluctuations from continuing operations. Due to the growing significance of the percentage rents, we have concluded it is in the investor’s best interest to receive the percentage rents in their entirety during the quarter received instead of ratably throughout the year. This has the added benefit of not creating the opportunity for a new unit purchaser to benefit from percentage rent distributions actually earned in the prior year by the unit seller.

Accordingly, we will be distributing $575,000 for Q1, including $465,000 of percentage rents. Obviously, the remaining three quarters of distributions for 2013 will be dramatically lower without the inclusion each quarter of 25% of the percentage rents earned for the prior year.

DISTRIBUTION HIGHLIGHTS …

$575, 000 ($12.42 per unit) will be distributed for the first quarter of 2013, including $465,000 ($10.05 per unit) of percentage rents.

Between $1,629.97 and $1,480.79 is the range of cumulative total distributions per unit from the first unit sold to the last unit sold before the offering closed (3/90), respectively. (Distributions are from both adjusted cash flow from operations and “net” cash activity from financing and investing activities).

Based on current projections, the Partnership anticipates distributing an aggregate of $950,000 ($20.53 per unit) from adjusted operating cash flows and “net” cash activity from investing and financing activities for the four quarters of 2013. We are not projecting any property sales in 2013.

MT. PLEASANT, SC CONDEMNATION PROCEEDINGS UPDATE

• When can I expect to receive my Partnership K-1?

According to IRS regulations, Management is not required to mail K-1’s until April 15^th, 2013. The 2012 K-1’s were mailed in the first week March of 2013.

• What was the estimated December 31, 2012 Net Unit Value (“NUV”)?

Management had estimated the December 31, 2012 Net Unit Value of each interest of the Partnership to approximate $340, as noted in the letter mailed to investors on February 15, 2013. Please note that the estimated year-end NUV should be adjusted (reduced) for any subsequent property sale(s) or applicable impairment write-downs during the following year. As with any valuation methodology, the General Partner’s methodology is based upon a number of estimates and assumptions that may not be accurate or complete. Different parties with different assumptions and estimates could derive a different estimated NUV. Accordingly, with respect to the estimated NUV, the Partnership can give no assurance that:

• How can I obtain hard copies of Quarterly and Annual Reports or other SEC filings?

Please visit the Investor Relations page at the Partnership website at www.divallproperties.com or the SEC website at www.sec.gov to print a copy of the report(s) or contact Investor Relations.

• What is the meaning of the word “Insured” in the name of this investment?

In the offering materials from the late 1980’s, sponsored by the former general partners, there was a representation (but no “guarantee”) that the Partnership would seek to insure rents from vacant properties. Although, there was some initial availability of very restrictive and limited (one year) insurance, that availability vanished in the early 1990’s.

In other words, the former general partners were “fast and loose” with professing the concept of “Insured” and the next and final partnership they sold did not use the term in the investment’s name.
