                                 CERTIFICATIONS

I, Joseph A. Varnas, President of The UBS FUNDS certify that:

1.    I have reviewed this report on Form N-CSR of The UBS FUNDS;

2.    Based on my knowledge, this report does not contain any untrue statement
      of a material fact or omit to state a material fact necessary to make the
      statements made, in light of the circumstances under which such statements
      were made, not misleading with respect to the period covered by this
      report;

3.    Based on my knowledge, the financial statements, and other financial
      information included in this report, fairly present in all material
      respects the financial condition, results of operations, changes in net
      assets, and cash flows (if the financial statements are required to
      include a statement of cash flows) of the registrant as of, and for, the
      periods presented in this report;

4.    The registrant's other certifying officer(s) and I are responsible for
      establishing and maintaining disclosure controls and procedures (as
      defined in Rule 30a-3(c) under the Investment Company Act of 1940) for the
      registrant and have:

                (a) Designed such disclosure controls and procedures, or caused
                    such disclosure controls and procedures to be designed under
                    our supervision, to ensure that material information
                    relating to the registrant, including its consolidated
                    subsidiaries, is made known to us by others within those
                    entities, particularly during the period in which this
                    report is being prepared;

                (b) Evaluated the effectiveness of the registrant's disclosure
                    controls and procedures and presented in this report our
                    conclusions about the effectiveness of the disclosure
                    controls and procedures, as of a date within 90 days prior
                    to the filing date of this report based on such evaluation;
                    and

                (c) Disclosed in this report any change in the registrant's
                    internal control over financial reporting that occurred
                    during the registrant's most recent fiscal half-year (the
                    registrant's second fiscal half-year in the case of an
                    annual report) that has materially affected, or is
                    reasonably likely to materially affect, the registrant's
                    internal control over financial reporting; and

5.    The registrant's other certifying officer(s) and I have disclosed to the
      registrant's auditors and the audit committee of the registrant's board of
      directors (or persons performing the equivalent functions):

<Page>

                (a) All significant deficiencies and material weaknesses in the
                    design or operation of internal control over financial
                    reporting which are reasonably likely to adversely affect
                    the registrant's ability to record, process, summarize, and
                    report financial information; and

                (b) Any fraud, whether or not material, that involves management
                    or other employees who have a significant role in the
                    registrant's internal control over financial reporting.
