TO:       UNIT HOLDERS OF CENTURY PROPERTIES GROWTH FUND XXII

SUBJECT:  OFFER TO PURCHASE UNITS AT HIGHER PRICE AND EXTENSION OF EXPIRATION
          DATE


Dear Unit Holder:

We are amending the Offer to Purchase and related Letters of Transmittal sent to
you on May 3, 2007, (the "Offer"), which was made by the Purchasers identified
in the Offer. The Purchasers are offering to purchase up to 20,000 Units of
limited partnership interest (the "Units") in CENTURY PROPERTIES GROWTH FUND
XXII (the "Partnership") at the increased Offer Price of:

                                  $150 per Unit
                                  -------------

The Offer will provide you with an opportunity to liquidate all, or a portion
of, your investment in CENTURY PROPERTIES GROWTH FUND XXII without the usual
transaction costs associated with market sales or partnership transfer fees.
Reasons you may wish to sell your Units include:

     o    GP REMAINS  NEUTRAL.  The General Partner has remained  neutral in its
          recommendation regarding our Offer.

     o    UNCERTAINTY  OF PARTNERSHIP  TERMINATION.  Our offer provides you with
          the opportunity to receive a guaranteed amount of money in a specified
          time  period.  The general  partner has given no  indication  when the
          partnership will be liquidating.  The Partnership term extends through
          2016!

     o    NO FUTURE IRS FILING REQUIREMENTS. The tax year in which you sell your
          Units will be the final year for which you will be obligated to file a
          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 potential sellers should consult their individual tax
          advisers.

The Purchasers are extending the Expiration Date to July 15, 2007. You can view
the amended Offer materials at www.mpfi.com (Click on MPF Tenders). If you
already completed and sent a Letter of Transmittal to the Depositary, you need
not send another, you will automatically receive the higher price. Please note
that a Medallion Guarantee is no longer required.

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:
