                                    PART III

                                    NARRATIVE

     The registrant's principal subsidiary, United Breweries International (UK)
Limited ("UBI") and UBI's own subsidiary UBSN, Ltd., operate primarily in the
United Kingdom, and provide the registrant with independently audited annual
financial statements. This year, due to late-arising issues affecting those
subsidiaries, those financial statements were not made available to the
registrant in a timely fashion. Although the registrant believes that it has now
received the substance of these financial statements, the actual report, signed
by the auditors, had not been received as of the date of this filing. That
delay, coupled with the unaccustomed additional burden of filing its Annual
Report for the first time on Form 10-K instead of Form 10-KSB, has caused the

                                       2


registrant significant difficulties in preparing its Annual Report in a timely
manner.

     The registrant is also in the process of addressing certain ongoing
liquidity issues. It is a party to a credit agreement which is scheduled to
expire on April 30, 2005, and a borrower under a temporary loan which is
expected to expire on or about April 30, 2005. Both the credit agreement and the
loan in question are secured by substantially all of the registrant's assets.
Additionally, on July 31, 2003, the Company entered into a payment plan with
Mendocino County to settle certain claims of the County related to delinquent
property taxes. The balance of the overdue taxes and related charges is due to
be paid in four annual installments, of $143,000 each, the next of which is due
on or before April 10, 2005. Failure to make the tax payment when due would
constitute a breach of the registrant's agreement with the County, and because
of the County's ability to sell the Ukiah property to satisfy a delinquency,
failure to settle these tax issues (including payments due under the payment
plan) could have a serious adverse effect on the Company's business and
financial condition.

     The Company is currently in discussions with potential new lenders which
may provide financing to replace the existing loan and credit facility, and to
provide funds with which to satisfy the Company's obligations to the County.
While management believes that it is likely to be successful in extending its
existing loan agreements or in refinancing them, a failure to do so would have a
significant impact on the Company's liquidity and operations. The registrant is
engaged in ongoing discussions with its independent auditors as to the effect of
these issues on the registrant's financial statements and the auditor's ability
to provide an unqualified independent report thereon. In addition to its
continuing discussions with these current and potential lenders, the registrant
is also currently in the process of attempting to obtain some form of credit
enhancement, from one or more of its affiliates. There can be no assurance,
however, that its efforts in this regard will be successful.

     For the above reasons, the registrant is unable to timely file its annual
report on Form 10-K for the year ended December 31, 2004, without unreasonable
effort or expense.

                                     PART IV
