     Item 27.  Indemnification
                ---------------

     Article Eleventh of the Amended and Restated Articles of Incorporation
     provides that the directors and officers of the Registrant shall not be
     liable to the Registrant or to any of its stockholders for monetary
     damages to the maximum extent permitted by applicable law.  Article
     Eleventh also provides that any repeal or modification of Article Eleventh
     or adoption, or modification of any other provision of the Articles or By-
     Laws inconsistent with Article Eleventh shall not adversely affect any
     limitation of liability of any director or officer of the Registrant with
     respect to any act or failure to act which occurred prior to such repeal,
     modification or adoption.

     Article Eleventh of the Amended and Restated Articles of Incorporation and
     Section 10.01 of Article X of the By-Laws provide that the Registrant
     shall indemnify and advance expenses to its present and past directors,
     officers, employees and agents, and any persons who are serving or have
     served at the request of the Registrant as a director, officer, employee
     or agent of another corporation, partnership, joint venture, trust, or
     enterprise, to the fullest extent permitted by law.

     Section 10.02 of Article X of the By-Laws further provides that the
     Registrant may purchase and maintain insurance on behalf of any person who
     is or was a director, officer or employee of the Registrant, or is or was
     serving at the request of the Registrant as a director, officer or
     employee of a corporation, partnership, joint venture, trust or other
     enterprise against any liability asserted against him or out of his or her
     status as such whether or not the Registrant would have the power to
     indemnify him or her against such liability.

     Section 9 of the Investment Advisory and Administration Contract provides
     that Mitchell Hutchins Asset Management Inc. ("Mitchell Hutchins") shall
     not be liable for any error of judgment or mistake of law or for any loss
     suffered by Registrant in connection with the matters to which the
     Contract relates except for a loss resulting from willful misfeasance, bad
     faith or gross negligence of Mitchell Hutchins in the performance of its
     duties or from its reckless disregard of its obligations and duties under
     the Contract.  Section 9 further provides that any person, even though
     also an officer, partner, employee or agent of Mitchell Hutchins, who may
     be or become an officer, director, employee or agent of Registrant shall
     be deemed, when rendering services to the Registrant or acting with
     respect to any business of the Registrant, to be rendering such service to
     or acting solely for the Registrant and not as an officer, partner,
     employee, or agent or one under the control or direction of Mitchell
     Hutchins even though paid by it.

     Section 9 of each Distribution Contract provides that the Registrant will
     indemnify Mitchell Hutchins and its officers, directors or controlling
     persons against all liabilities arising from any alleged untrue statement
     of material fact in the Registration Statement or from alleged omission to
     state in the Registration Statement a material fact required to be stated
     in it or necessary to make the statements in it, in light of the
     circumstances under which they were made, not misleading, except insofar
     as liability arises from untrue statements or omissions made in reliance
     upon and in conformity with information furnished by Mitchell Hutchins to
     the Registrant for use in the Registration Statement; and provided that
     this indemnity agreement shall not protect any such persons against
     liabilities arising by reason of their bad faith, gross negligence or
     willful misfeasance; and shall not inure to the benefit of any such
     persons unless a court of competent jurisdiction or controlling precedent
     determines that such result is not against public policy as expressed in
     the Securities Act of 1933.  Section 9 of each Distribution Contract also
     provides that Mitchell Hutchins agrees to indemnify, defend and hold the
     Registrant, its officers and directors free and harmless of any claims
     arising out of any alleged untrue statement or any alleged omission of
     material fact contained in information furnished by Mitchell Hutchins for
     use in the Registration Statement or arising out of an agreement between
     Mitchell Hutchins and any retail dealer, or arising out of supplementary
     literature or advertising used by Mitchell Hutchins in connection with
     each Distribution Contract.

     Section 9 of each Exclusive Dealer Agreement contains provisions similar
     to Section 9 of each Distribution Contract, with respect to PaineWebber
     Incorporated ("PaineWebber").

     Section 7 of the Service Contract provides that PaineWebber shall be
     indemnified and held harmless by the Registrant against all liabilities,
     except those arising out of bad faith, gross negligence, willful
     misfeasance or reckless disregard of its duties under the Service
     Contract.

     Insofar as indemnification for liabilities arising under the Securities
     Act of 1933, as amended, may be provided to directors, officers and
     controlling persons of the Registrant, pursuant to the foregoing
     provisions or otherwise, the Registrant has been advised that in the
     opinion of the Securities and Exchange Commission such indemnification is
     against public policy as expressed in the Act and is, therefore,
     unenforceable.  In the event that a claim for indemnification against such
     liabilities (other than the payment by the Registrant of expenses incurred
     or paid by a director, officer or controlling person of the Registrant in
     connection with the successful defense of any action, suit or proceeding
     or payment pursuant to any insurance policy) is asserted against the
     Registrant by such director, officer or controlling person in connection
     with the securities being registered, the Registrant will, unless in the
     opinion of its counsel the matter has been settled by controlling
     precedent, submit to a court of appropriate jurisdiction the question
     whether such indemnification by it is against public policy as expressed
     in the Act and will be governed by the final adjudication of such issue.

                           PAINEWEBBER MASTER SERIES, INC.
                      MULTIPLE CLASS PLAN PURSUANT TO RULE 18f-3

              PaineWebber Master Series, Inc. hereby adopts this amended and
     restated Multiple Class Plan pursuant to Rule 18f-3 under the Investment
     Company Act of 1940, as amended ("1940 Act") on behalf of its current
     operating series, PaineWebber Balanced Fund and PaineWebber Money Market
     Fund, and any series that may be established in the future (referred to
     hereinafter collectively as the "Funds" and individually as a "Fund").  

     A.       GENERAL DESCRIPTION OF CLASSES THAT ARE OFFERED:
              -----------------------------------------------

              1.      Class A Shares.    Class A shares of each Fund are sold
     to the general public subject to an initial sales charge.  The initial
     sales charge for each Fund is waived for certain eligible purchasers and
     reduced or waived for certain large volume purchases.

              The maximum sales charge is 4% of the public offering price for
     Class A shares of any other Fund that invests primarily in debt
     securities.

              The maximum sales charge is 4.5% of the public offering price for
     Class A shares of a Fund that invests primarily in equity securities or a
     combination of equity and debt securities.

              Class A shares of each Fund are subject to an annual service fee
     of .25% of the average daily net assets of the Class A shares of each Fund
     paid pursuant to a plan of distribution adopted pursuant to Rule 12b-1
     under the 1940 Act.

              Class A shares of each Fund will be subject to a contingent
     deferred sales charge ("CDSC") on redemptions of shares (i) purchased
     without an initial sales charge due to a sales charge waiver for purchases

              ---------------------------------

              Certain expenses may be attributable to a particular Class of
     shares of each Fund ("Class Expenses").  Class Expenses are charged
     directly to the net assets of the particular Class and, thus, are borne on
     a pro rata basis by the outstanding shares of that Class.

     each Class may also pay a different amount of the following other
     expenses:

              (1)     printing and postage expenses related to
                      preparing and distributing materials such as
                      shareholder reports, prospectuses, and proxies to
                      current shareholders of a specific Class;

              (2)     Blue Sky registration fees incurred by a specific Class
                      of shares;

              (3)     SEC registration fees incurred by a specific Class of
                      shares;

              (4)     expenses of administrative personnel and services
                      required to support the shareholders of a specific Class
                      of shares;

              (5)     Directors' fees incurred as a result of issues relating
                      to a specific Class of shares;

              (6)     litigation expenses or other legal expenses relating to a
                      specific Class of shares; and  

              (7)     transfer agent fees identified as being attributable to a
                      specific Class.

     C.       EXCHANGE PRIVILEGES:
              -------------------

              Class A, Class B and Class C shares of each Fund may be exchanged
     for shares of the corresponding Class of other PaineWebber mutual funds
     and MH/KP mutual funds, or may be acquired through an exchange of shares
     of the corresponding Class of those funds.  Class Y shares of the Funds
     are not exchangeable.

              These exchange privileges may be modified or terminated by a
     Fund, and exchanges may only be made into funds that are legally
     registered for sale in the investor's state of residence.
