Exhibit (a)(4)





             [Published March 23, 2005 in Investor's Business Daily]

sell Units. These Offers are being made solely by the formal Offers to Purchase
forwarded to Unit holders of record and are not being made to, and tenders will
not be accepted from or on behalf of, Unit holders residing in any jurisdiction
in which making or accepting the Offers would violate that jurisdiction's laws.

Offers to be made by a licensed broker or dealer, the Offers shall be deemed to
be made on behalf of Purchasers only by one or more registered dealers licensed
under the laws of such jurisdiction.

The Purchasers are offering to purchase for cash up to 2,000 Units of Limited
Partnership Interest ("Units") of the Partnership, at a price of $55 per Unit
upon the terms and subject to the conditions set forth in Purchasers' Offer to
Purchase and in the related Letter of Transmittal for the offer (which together

THE OFFERS AND WITHDRAWAL RIGHTS EXPIRE AT 12:00 MIDNIGHT, PACIFIC DAYLIGHT
TIME, ON MAY 6, 2005, UNLESS AN OFFER IS EXTENDED.

Funding for the purchase of the Units will be provided through the Purchasers'
existing working capital. The Offers are not made for the purpose of acquiring
or influencing control of the business of the issuer. The Offers will expire at
12:00 midnight, Pacific Daylight Time on May 6, 2005, unless and until
Purchasers, in their sole discretion, shall have extended the period of time for
which the Offers are open (such date and time, as extended the "Expiration
Date"). The Purchasers will not provide a subsequent offering period following
the Expiration Date. If Purchasers make a material change in the terms of the
Offers, or if they waive a material condition to the Offers, Purchasers will
extend the Offers and disseminate additional tender offer materials to the
extent required by Rules 14d-4(c) and 14d-6(d) under the Securities Exchange Act
of 1934, as amended (the "Exchange Act"). The minimum period during which the
Offers must remain open following any material change in the terms of the
Offers, other than a change in price or a change in percentage of securities
sought or a change in any dealer's soliciting fee, will depend upon the facts
and circumstances including the materiality of the change with respect to a
change in price or, subject to certain limitations, a change in the percentage
of securities ought or a change in any dealer's soliciting fee. A minimum of ten
business days from the date of such change is generally required to allow for
adequate dissemination to Unit holders. Accordingly, if prior to the Expiration
Date, Purchasers increase (other than increases of not more than two percent of
the outstanding Units) or decrease the number of Units being sought, or increase
or decrease the consideration offered pursuant to the Offers, and if the Offers
are scheduled to expire at any time earlier than the period ending on the tenth
business day from the date that notice of such increase or decrease is first
published, sent or given to Unit holders, the Offers will be extended at least




until the expiration of such ten business days. For purposes of the Offers, a
"business day" means any day other than a Saturday, Sunday or federal holiday
and consists of the time period from 12:01 a.m. through 12:00 midnight, Pacific
Daylight Time. In all cases payment for the Units purchased pursuant to the
Offers will be made only after timely receipt of the Letters of Transmittal (or
facsimiles thereof), properly completed and duly executed, with any required
signature guarantees, and any other documents required by such Letters of
Transmittal.

Tenders of Units made pursuant to the Offers are irrevocable, except that Unit
holders who tender their Units in response to the Offers will have the right to
withdraw their tendered Units at any time prior to the Expiration Date by
sending to MacKenzie Patterson Fuller, Inc. a written or facsimile transmission
notice of withdrawal identifying the name of the person who tendered Units to be
withdrawn, signed by the same persons and in the same manner as the Letter of
Transmittal tendering the Units to be withdrawn. In addition, tendered Units may
be withdrawn at any time on or after May 20, 2005, unless the tender has
theretofore been accepted for payment as provided above. If tendering Unit
holders tender more than the number of Units that Purchasers seek to purchase
pursuant to the Offers for those Units, Purchasers will take into account the
number of Units so tendered and take up and pay for as nearly as may be pro
rata, disregarding fractions, according to the number of Units tendered by each
tendering Unit holder during the period during which that Offers remain open.
The terms of the Offers are more fully set forth in the formal Tender Offer
Documents which are available from Purchasers at the Purchasers' expense. The
Offers contain terms and conditions and the information required by Rule
14d-6(d)(1) under the Exchange Act which are incorporated herein by reference.
The Tender Offer Documents contain important information which should be read
carefully before any decision is made with respect to the Offer.

The Tender Offer Documents may be obtained by written request to Purchasers or
as set forth below. A request has been made to the Partnership pursuant to Rule
14d-5 under the Exchange Act for the use of its list of Unit holders for the
purpose of disseminating the Offers to Unit holders. Upon compliance by the
Partnership with such request, the Tender Offer Documents and, if required,
other relevant materials will be mailed at the Purchasers' expense to record
holders of Units, brokers, banks and similar persons whose names appear or whose
nominee appears on the list of securities holders, or persons who are listed as
participants in a clearing agency's security position listing, for subsequent
transmittal to beneficial owners of Units.
