Dear Unit Holder:

We are amending for a second time the Offer to Purchase and related Letters of
Transmittal sent to you on September 22, 2004, and amended October 5, 2004 (the
"Offer"), which was made by MP FALCON GROWTH 2, LLC; MP VALUE FUND 6, LLC; MPF
DEWAAY FUND 2, LLC; MP INCOME FUND 18, LLC; MACKENZIE PATTERSON SPECIAL FUND 7,
LLC; ACCELERATED HIGH YIELD INSTITUTIONAL INVESTORS, L.P.; MACKENZIE SPECIFIED
INCOME FUND, L.P.; MACKENZIE PATTERSON SPECIAL FUND 5, LLC; MP INCOME FUND 16,
LLC (collectively the "Purchasers"). The Purchasers are offering to purchase up
to 100,000 Units of limited partnership interest (the "Units") in SECURED INCOME
L.P., a Delaware limited partnership (the "Partnership"). As amended, the Offer
Price is now equal to:

                                 $34.00 per Unit

The Offer will provide you with an opportunity to liquidate all, or a portion
of, your investment in SECURED INCOME L.P. without the usual transaction costs
associated with market sales or partnership transfer fees.

The Purchasers are increasing the Offer Price by amending the Offer, as noted
above, by extending the Expiration Date to November 5, 2004, and by making the
following additional disclosures:

After carefully reading the Offer as amended, if you elect to tender your Units,
mail (using the enclosed pre-addressed, postage paid envelope) or fax a duly
completed and executed copy of the Letter of Transmittal (printed on green
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 previously tendered your Units to WEST PUTNAM HOUSING INVESTORS III
LLC (the "General Partner Affiliate") pursuant to its Tender Offer dated

Units pursuant to this Offer. We have enclosed a notice of withdrawal that you
may use to revoke your tender to the General Partner Affiliate.

If you have any questions or need assistance, please call the Depository at
800-854-8357.

This Offer expires (unless extended) November 5, 2004
