Newbury Street Trust
82 Devonshire Street
Boston, Massachusetts 02109

Ladies and Gentlemen:

 You have requested our opinion, as counsel to Newbury Street Trust
(the "Trust"), as to certain matters regarding the issuance of Shares
of the Trust. As used in this letter, the term "Shares" means the
Capital Reserves Class and Daily Money Class shares of beneficial
interest of Prime Fund, Tax-Exempt Fund, and Treasury Fund, and the
Advisor B Class and Advisor C Class shares of beneficial interest of
Treasury Fund, each a series of the Trust.

 As such counsel, we have examined certified or other copies, believed
by us to be genuine, of the Trust's Trust Instrument and by-laws and
such resolutions and minutes of meetings of the Trust's Board of
Trustees as we have deemed relevant to our opinion, as set forth
herein. Our opinion is limited to the laws and facts in existence on
the date hereof, and it is further limited to the laws (other than the
conflict of law rules) in the State of Delaware that in our experience
are normally applicable to the issuance of shares by unincorporated
voluntary associations and to the Securities Act of 1933 ("1933 Act"),
the Investment Company Act of 1940 ("1940 Act") and the regulations of
the Securities and Exchange Commission ("SEC") thereunder.

 Based on present laws and facts, we are of the opinion that the
issuance of the Shares has been duly authorized by the Trust and that,
when sold in accordance with the terms contemplated by Post-Effective
Amendment No. 38 to the Trust's Registration Statement on Form N-1A
and each subsequent Post-Effective Amendment ("PEA") to said
registration statement, including receipt by the Trust of full payment
for the Shares and compliance with the 1933 Act and the 1940 Act and
applicable state law regulating the offer and sale of securities, the
Shares will have been validly issued, fully paid and non-assessable.

 The Trust is a business trust established pursuant to the Delaware
Business Trust Act ("Delaware Act").  The Delaware Act provides that a
shareholder of the Trust is entitled to the same limitation of
personal liability extended to shareholders of for-profit
corporations.  To the extent that the Trust or any of its shareholders
become subject to the jurisdiction of courts in states that do not
have statutory or other authority limiting the liability of business
trust shareholders, such courts might not apply the Delaware Act and
could subject Trust shareholders to liability.

 To guard against this risk, the Trust's Trust Instrument provides
that the Trustees shall have no power to bind any shareholder
personally or to call upon any shareholder for the payment of any sum
of money or assessment whatsoever other than such as the shareholder
may at any time personally agree to pay by way of subscription for any
shares or otherwise.  The Trust Instrument also requires that every
note, bond, contract or other undertaking issued by or on behalf of
the Trust or the Trustees relating to the Trust or to a Series shall
include a recitation limiting the obligation represented thereby to
the Trust or to one or more Series and its or their assets (although
the omission of such a recitation shall not operate to bind any
shareholder of the Trust).  Furthermore, the Trust Instrument provides
that:  (i) in case any shareholder or former shareholder of any Series
shall be held to be personally liable solely by reason of his being or
having been a shareholder of such Series and not because of his acts
or omissions or for some other reason, the shareholder or former
shareholder shall be entitled out of the assets belonging to the
applicable Series to be held harmless from and indemnified against all
loss and expense arising from such liability; and (ii) the Trust, on
behalf of the affected Series, shall, upon request by the shareholder,
assume the defense of any claim made against the shareholder for any
act or obligation of the Series and satisfy any judgment thereon from
the assets of the Series.

 We hereby consent to this opinion accompanying or being incorporated
by reference in the PEA when it is filed with the SEC.

      Very truly yours,

      KIRKPATRICK & LOCKHART LLP
