TO HOLDERS OF ORIGINAL UNITS OF
INCOME GROWTH PARTNERS, LTD. X

         Re:      Offer to Purchase Original Units for $850 Per Unit

Dear Unit Holder:

     Enclosed is an OFFER TO PURCHASE up to 1,880 Original Units of limited
partnership interests in Income Growth Partners, Ltd. X (the "Partnership") at a
cash purchase price of $850 per Original Unit, without interest, less the amount
of distributions made to you after the date of the Offer, and less any transfer
fees imposed by the Partnership, which the Partnership advises us are $40 per
transfer (regardless of the number of Units transferred).

     Please consider the following points, which are discussed in greater detail
in the accompanying Offer to Purchase:

     o    $850 per Original Unit equals the amount of net proceeds the Purchaser
          estimates would be distributed if the Partnership's properties were
          sold for the value estimated in the appraisal obtained by the General
          Partner, dated May 8, 2002.

     o    The Offer price exceeds by $199 per unit (30%) the highest prior offer
          for Original Units of which Purchaser is aware, and exceeds by at
          least $463 per unit (120%) the average price per unit for trades of
          Partnership interests reported over the last 12 months.

     o    No distributions can be made on the Original Units until approximately
          $4.1 Million ($510 per unit) more is distributed on the Class A Units,
          which would take 4 to 5 years at the rate of distributions made on the
          Class A Units over the last two years. No distributions have ever been
          made on the Original Units.

     o    A sale of all Partnership units would eliminate the need to file Form
          K-1 information for the Partnership for years after 2003.

     The Partnership's general partner advised the Purchaser in March 2003 that
the Partnership was going to list its properties for sale, but the Purchaser
does not know whether or not any efforts to sell the properties are being made.
We urge you to read the Offer to Purchase completely and to return your
completed Agreement of Transfer and Letter of Transmittal promptly (blue form)
in the envelope provided.

     The Offer is scheduled to expire on May 19, 2003. For answers to any
questions you might have regarding these materials or our Offer, or assistance
in the procedures for accepting our Offer and tendering your Units, please
contact us at (800) 611-4613 (toll free).

                                             Very truly yours,

                                             MILLENIUM MANAGEMENT, LLC
