EXPLANATORY NOTE

The sole purpose of this
amendment to our Annual Report on Form 10-K for the year ended December 31, 2012, originally filed with the Securities and Exchange
Commission on March 29, 2013 (the “Original Form 10-K”), is to amend Item 9A. CONTROLS AND PROCEDURES to reflect that
the Partnership’s disclosure controls and procedures were not effective.

No other changes have been
made to the Original Form 10-K and the Original Form 10-K has not been updated to reflect events occurring subsequent to the original
filing date.




ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures



The Partnership’s management, with the participation of the
principal executive officer and principal financial officer of DSI Properties, Inc., its General Partner, who are the equivalent
of the Partnership’s principal executive officer and principal financial officer, respectively, has evaluated the effectiveness
of the Partnership’s disclosure controls and procedures (as defined in Rules 13a-15(e) under the Securities Exchange Act
of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on
such evaluation, the principal executive officer and principal financial officer of the General Partner, who are the equivalent
of the Partnership’s principal executive officer and principal financial officer, respectively, have concluded that, as of
the end of such period, the Partnership’s disclosure controls and procedures were not effective.

Management’s Annual Report on Internal Control Over Financial
Reporting

The Partnership’s management is responsible for establishing
and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule
13a-15(f) under the Exchange Act as a process designed by, or under the supervision of, the principal executive and principal financial
officers of the General Partner, who are the equivalent of the Partnership’s principal executive officer and principal financial
officer, respectively, and effected by the Partnership’s management and other personnel to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles and includes those policies and procedures that:

| | · | pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of assets;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------



| | · | provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of the Partnership’s management; and
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the financial statements.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject
to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies
or procedures may deteriorate.

Internal Controls Over Financial Reporting

The Partnership's management assessed the effectiveness of the Partnership's
internal control over financial reporting as of December 31, 2012. In making this assessment, the Partnership's management
used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated
Framework. Based on their assessment, the Partnership's management concluded that, as of December 31, 2012, the Partnership's internal
control over financial reporting was not effective.

A “material weakness” is a deficiency, or combination of deficiencies, in internal control over financial reporting,
such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not
be prevented or detected on a timely basis.



A “significant deficiency” is a
deficiency, or combination of deficiencies, in internal control over financial reporting that is less severe than a material weakness,
yet important enough to merit attention by those responsible for oversight of our financial reporting.



The following significant deficiency
(as defined above) was identified, which in combination with other deficiencies may constitute a material weakness (as defined
above):



| | · | We did not properly implement the controls to detect errors in year-end close reconciliations and adjusting journal entries.
| | - | ----------------------------------------------------------------------------------------------------------------------------



To the knowledge of the Partnership’s
management, including the Partnership’s PEO and PFO, the aforementioned significant deficiency has not led to a misstatement
of our results of operations for the year ended December 31, 2012, or statement of financial position as of December 31, 2012. The
Partnership’s management is implementing improved year-end close checklists and review procedures to remediate the above
noted significant deficiency.

This annual report does not include an attestation report of the
Partnership’s registered public accounting firm regarding internal control over financial reporting. Management’s report
was not subject to the attestation by the Partnership’s registered public accounting firm pursuant to rules of the Securities
and Exchange Commission that permit the Partnership to provide only management’s report in this annual report.

Changes in Internal Control Over Financial Reporting.

There have been no significant
changes in the Partnership’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under
the Exchange Act) during the fourth quarter of 2012, except as noted above, that have materially affected, or are reasonably likely
to materially affect, the Partnership’s internal control over financial reporting.
