Ladies and Gentlemen:

          We have acted as special Delaware counsel to MediaOne Finance 
Trust III, MediaOne Finance Trust IV, MediaOne Finance Trust V and MediaOne 
Finance Trust VI, each a Delaware statutory business trust (collectively 
referred to herein as the "MediaOne Finance Trusts" and each individually as 
a "MediaOne Finance Trust"), in connection with certain matters relating to 
the creation of the MediaOne Finance Trusts and the proposed issuance of 
Preferred Securities therein to beneficial owners pursuant to and as 
described in Registration Statement Nos. 333-65371, 333-65371-01, 
333-65371-02, 333-65371-03, 333-65371-04 and 333-65371-05 (and the prospectus 
forming a part thereof) on Form S-3 filed with the Securities and Exchange 
Commission (the "Commission") by MediaOne Group, Inc., a Delaware corporation 
(the "Company"), MediaOne Group Funding, Inc., a Delaware corporation 
("Funding"), and the MediaOne Finance Trusts on October 6, 1998 (as so filed 
and hereafter amended, the "Registration Statement").  Capitalized terms used 
herein and not otherwise herein defined are used with respect to each 
MediaOne Finance Trust as defined in the draft dated October 13, 1998 - 5:11 
PM of the form of Amended and Restated Declaration of Trust (the "Draft 
Governing Instrument").

          In rendering this opinion, we have examined copies of the following 
documents in the forms provided to us:  the Certificates of Trust of each 
MediaOne Finance Trust, each as filed in the Office of the Secretary of the 
State of Delaware (the "State Office") on October 5, 1998 (the Certificate of 
Trust of each MediaOne Finance Trust is referred to herein as a 
"Certificate"); the Declaration of Trust of each MediaOne Finance Trust, each 
dated as of October 5, 1998 (the Declaration of Trust of each MediaOne 
Finance Trust is referred to herein

as an "Original Governing Instrument"); the Draft Governing Instrument; the 
Indenture dated as of June 12, 1998 between the Company, Funding and Norwest 
Bank Minnesota, National Association, as Trustee and the form of Supplemental 
Indenture to be entered into in connection therewith; the form of Preferred 
Securities Guarantee to be made by the Company and the First National Bank of 
Chicago, as trustee, with respect to each MediaOne Finance Trust (each, a 
"Guarantee Agreement"); the Registration Statement as originally filed with 
the Commission; and a certification of good standing of each MediaOne Finance 
Trust obtained as of a recent date from the State Office.  In such 
examinations, we have assumed the genuineness of all signatures, the 
conformity to original documents of all documents submitted to us as drafts 
or copies or forms of documents to be executed and the legal capacity of 
natural persons to complete the execution of documents.  We have further 
assumed for purposes of this opinion:  (i) the due formation, organization or 
creation, valid existence and good standing of each MediaOne Finance Trust 
and each entity that is a party to any of the documents reviewed by us under 
the laws of the jurisdiction of its respective formation, organization or 
creation; (ii) the due authorization, execution and delivery by, or on behalf 
of, each of the parties thereto of the above referenced documents with 
respect to each MediaOne Finance Trust; (iii) that the Company, The First 
National Bank of Chicago, First Chicago Delaware Inc. and the appropriate 
Regular Trustees will duly authorize, execute and deliver an amended and 
restated declaration of trust for each MediaOne Finance Trust in the form of 
the Draft Governing Instrument (each, a "Governing Instrument") and all other 
documents contemplated thereby or by the Registration Statement to be 
executed in connection with the creation of each MediaOne Finance Trust and 
the issuance by each MediaOne Finance Trust of Preferred Securities, in each 
case prior to the first issuance of Preferred Securities of such MediaOne 
Finance Trust; (iv) that the Preferred Securities of each MediaOne Finance 
Trust will be offered and sold pursuant to the prospectus forming a part of 
the Registration Statement and a prospectus supplement thereto (collectively, 
the "Prospectus") that will be consistent with, and accurately describe, the 
terms of the applicable Governing Instrument and the applicable Guarantee 
Agreement relating to each such MediaOne Finance Trust and all other relevant 
documents; (v) that no event has occurred subsequent to the filing of any 
Certificate, or will occur prior to the issuance of all Preferred Securities 
by each MediaOne Finance Trust, that would cause a dissolution or liquidation 
of any MediaOne Finance Trust under the applicable Original Governing 
Instrument or the applicable Governing Instrument; (vi) that the activities 
of each MediaOne Finance Trust have been and will be conducted in accordance 
with its Original Governing Instrument or Governing Instrument, as 
applicable, and the Delaware Business Trust Act, 12 DEL. C. Sections 3801 ET 
SEQ. (the "Delaware Act"); (vii) that prior to the first issuance of 
Preferred Securities by each MediaOne Finance Trust, payment of the required 
consideration therefor will have been made in accordance with the terms and 
conditions of the applicable Governing Instrument and as described in the 
Prospectus, and that the Preferred Securities of each MediaOne Finance Trust 
are otherwise issued and sold in accordance with the terms, conditions, 
requirements and procedures set forth in the Governing Instrument of such 
MediaOne Finance Trust and as described in the Prospectus; and (viii) that 
the documents examined by us, or contemplated hereby, express the entire 
understanding of the parties thereto with respect to the subject matter 
thereof and have not been, and, prior to the issuance of all Preferred 
Securities by each MediaOne Finance Trust, will not

be, amended, supplemented or otherwise modified, except as herein referenced. 
 No opinion is expressed with respect to the requirements of, or compliance 
with, federal or state securities or blue sky laws.  Further, we express no 
opinion with respect to the Registration Statement or any other offering 
materials relating to the Preferred Securities offered by any MediaOne 
Finance Trust and we assume no responsibility for their contents.  As to any 
fact material to our opinion, other than those assumed, we have relied 
without independent investigation on the above referenced documents and on 
the accuracy, as of the date hereof, of the matters therein contained.

          Based on and subject to the foregoing, and limited in all respects 
to matters of Delaware law, it is our opinion that, upon issuance, the 
Preferred Securities of each MediaOne Finance Trust will constitute validly 
issued and, subject to the terms of the applicable Governing Instrument, 
fully paid and non-assessable beneficial interests in the assets of such 
MediaOne Finance Trust. We note that pursuant to each Governing Instrument, 
each MediaOne Finance Trust may withhold amounts otherwise distributable to a 
Holder of Securities in such MediaOne Finance Trust and pay over such amounts 
to the applicable jurisdictions in accordance with federal, state and local 
law and any amounts withheld will be deemed to have been distributed to such 
Holder and that, pursuant to the Governing Instrument, the Preferred Security 
Holders of each MediaOne Finance Trust may be obligated to make payments or 
provide indemnity or security under the circumstances set forth therein.

          We hereby consent to the filing of this opinion as an exhibit to a 
pre-effective amendment to the Registration Statement and to the use of our 
name under the heading "LEGAL OPINIONS" in the prospectus forming a part 
thereof.  In giving this consent, we do not thereby admit that we come within 
the category of persons whose consent is required under Section 7 of the 
Securities Act of 1933, as amended, or the rules and regulations of the 
Commission thereunder.  This opinion speaks only as of the date hereof and is 
based on our understandings and assumptions as to present facts, and our 
review of the above referenced documents and the application of Delaware law 
as the same exist on the date hereof, and we undertake no obligation to 
update or supplement this opinion after the date hereof for the benefit of 
any person or entity with respect to any facts or circumstances that may 
hereafter come to our attention or any changes in facts or law that may 
hereafter occur or take effect.  This opinion is intended solely for the 
benefit of the addressees hereof in connection with the matters contemplated 
hereby and may not be relied upon by any other person or entity or for any 
other purpose without our prior written consent.


                              Very truly yours,

                              MORRIS, NICHOLS, ARSHT & TUNNELL

                              /s/  Morris, Nichols, Arsht & Tunnell
