Dear Unit Holder:

We are amending and extending the Offer to Purchase sent to you October 31, 2006
(the "Offer") made by MPF-NY 2006,  LLC; MPF DEWAAY PREMIER FUND,  LLC; MPF BLUE
RIDGE FUND I, LLC; MPF SENIOR NOTE PROGRAM I, LP; MPF FLAGSHIP  FUND 12, LLC; MP

MPF DEWAAY  PREMIER FUND 3, LLC; AND MPF  FLAGSHIP  FUND 11, LLC; AND  MACKENZIE
PATTERSON  FULLER,  LP  (collectively  the  "Purchasers"),  who are  offering to
purchase up to 15,000 Units of limited  partnership  interest  (the  "Units") in
CENTURY  PROPERTIES FUND XIX (the  "Partnership").  You may wish to consider the
following factors in deciding whether to sell your Units:

      o     The offer is hereby  amended to  increase  the price  payable to ALL
            Unitholders to $200 per Unit.

      o     This price is 33% per Unit higher than the original offer.

      o     The  Purchasers  are extending the  Expiration  Date to December 22,
            2006.

      o     If you sell your  Units to us this  year,  the 2006 tax year will be
            the final  year for which you will be  obligated  to file a Schedule
            K-1 for the Partnership  with your tax return.  This may represent a
            reduction in costs  associated with filing  complicated tax returns.
            Your decision to sell may have other  favorable or  unfavorable  tax
            consequences and you should consult your individual tax adviser.

As of the date hereof, 252 Units have yet been tendered by securities holders.
No other Units have been tendered to date. After carefully reading the enclosed
Offer, if you elect to tender your Units, mail (using the enclosed
pre-addressed, postage paid envelope) or fax (then mail) a duly completed and
executed copy of the Letter of Transmittal (printed on pink paper) and change of
address forms, and any other documents required by the Letter of Transmittal, to
the Depositary for the Offer at:

If you have any  questions or need  assistance,  please call the  Depository  at

be able to obtain a free copy of the Tender Offer  Statement on Schedule TO, the
Offer to  Purchase,  the  Supplemental  Letter  to  Unitholders,  the  Letter of
Transmittal,  and other  documents  that the  company  has  filed  with the U.S.

need to do anything as your Units are already  accounted  for by the  Purchasers
and you will automatically receive the higher Offer Price.

This Offer expires (unless extended) December 22, 2006.
