Dear Limited Partner:

           Enclosed is the Schedule 14D-9 which was filed by Angeles Partners
XI (the "Partnership") with the Securities and Exchange Commission in
connection with an offer (the "Offer") by Cooper River Properties, L.L.C., a
Delaware limited liability company (the "Purchaser"), Insignia Properties,
L.P., a Delaware limited partnership ("IPLP"), Insignia Properties Trust, a
Maryland real estate investment trust ("IPT"), and Insignia Financial Group,
Inc., a Delaware corporation ("Insignia," and together with IPLP, IPT and the
Purchaser, the "Bidders"), to purchase units of limited partnership interest
("Units") in the Partnership.

           The Partnership's managing general partner is Angeles Realty
Corporation II (the "Managing General Partner"), which is an affiliate of the
Bidders. Due to the affiliation between the Managing General Partner of the
Partnership and the Bidders, the Managing General Partner is subject to certain
conflicts of interest in connection with the response to the Offer.

           AS A RESULT OF THE EXISTING AND POTENTIAL CONFLICTS OF INTEREST,
NEITHER THE PARTNERSHIP NOR THE MANAGING GENERAL PARTNER EXPRESSES ANY OPINION
AS TO THE OFFER AND EACH IS REMAINING NEUTRAL AND MAKING NO RECOMMENDATION AS
TO WHETHER LIMITED PARTNERS SHOULD TENDER THEIR UNITS IN RESPONSE TO THE OFFER.

           Limited Partners are advised to carefully read the enclosed Schedule
14D-9.
