Exhibit (a)(4)







[Published November 16, 2007 in Investor's Business Daily]


This announcement is neither an offer to buy nor a solicitation of an offer to
sell Shares. The Offer is being made solely by the formal Offer to Purchase
forwarded to Shareholders of record and is not being made to, and tenders will
not be accepted from or on behalf of, Shareholders residing in any jurisdiction
in which making or accepting the Offer would violate that jurisdiction's laws.
In those jurisdictions where the securities, Blue Sky, or other laws require the
Offer to be made by a licensed broker or dealer, the Offer 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 138,180 shares of common
stock of AQQ ("AQQ Shares") at a price of $17.25 per Share and up to 79,649
Shares of common stock of BBC ("BBC Shares") upon the terms and subject to the
conditions set forth in respective Offers to Purchase and in the related Letters
of Transmittal for the offers (which together constitute the "Offer" and the
"Tender Offer Documents"). Collectively the BBC Purchasers and the AQQ
Purchasers may be referred to as the "Purchasers," AQQ and BBC may be referred
to as the "Companies," and the "AQQ Shares" and the "BBC Shares" may be referred
to as the "Shares."

THE OFFERS AND WITHDRAWAL RIGHTS EXPIRE AT 11:59 P.M., PACIFIC TIME, ON DECEMBER
21, 2007, UNLESS AN OFFER IS EXTENDED.

Funding for the purchase of the Shares 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 issuers. The Offers will expire at
11:59 p.m., Pacific Time on December 21, 2007, unless and until Purchasers, in
their sole discretion, shall have extended the period of time for which an Offer
is 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 an Offer, or if they waive a
material condition to an Offer, Purchasers will extend the Offer 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 Offer must remain open following any
material change in the terms of the Offer, 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 Shareholders.
Accordingly, if prior to the Expiration Date, Purchasers increase (other than
increases of not more than two percent of the outstanding Shares) or decrease
the number of Shares being sought, or increase or decrease the consideration
offered pursuant to an Offer, and if the Offer is 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
Shareholders, the Offer will be extended at least until the expiration of such
ten business days. For purposes of an Offer, 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 midnight, Pacific Time. In all cases payment for the
Shares purchased pursuant to an Offer 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, or, in the case of transmittal through
the Depository Trust Company, upon notification of the transfer.



Tenders of Shares made pursuant to an Offer is irrevocable, except that
Shareholders who tender their Shares in response to an Offer will have the right
to withdraw their tendered Shares at any time prior to the Expiration Date by
sending to MacKenzie Patterson Fuller, LP a written or facsimile transmission
notice of withdrawal identifying the name of the person who tendered Shares to
be withdrawn, signed by the same persons and in the same manner as the Letter of
Transmittal tendering the Shares to be withdrawn. In addition, tendered Shares
may be withdrawn at any time on or after January 15, 2008, unless the tender has
theretofore been accepted for payment as provided above. If tendering
Shareholders tender more than the number of Shares that Purchasers seek to
purchase pursuant to the Offer for those Shares, Purchasers will take into
account the number of Shares so tendered and take up and pay for as nearly as
may be pro rata, disregarding fractions, according to the number of Shares
tendered by each tendering Share holder during the period during which that
Offer remains open. The terms of the Offer are more fully set forth in the
formal Tender Offer Documents which are available from Purchasers at the
Purchasers' expense. The Offer contains 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 BBC pursuant to Rule 14d-5 under
the Exchange Act for the use of its list of Shareholders for the purpose of
disseminating the Offer to Shareholders. Upon compliance by BBC with such
request, the Tender Offer Documents and, if required, other relevant materials
will be mailed at the BBC Purchasers' expense to record holders of BBC Shares,
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 BBC Shares.
