                                   EXHIBIT B
                                   ---------

                           To Amendment No. 5 to the
                    First Amended and Restated Agreement of
             Limited Partnership of FrontierVision Partners, L.P.

                                   EXHIBIT C
                                   ---------

                           To Amendment No. 5 to the
                    First Amended and Restated Agreement of
             Limited Partnership of FrontierVision Partners, L.P.
             ----------------------------------------------------

   (i) The General Partner, with the approval of the Advisory Committee, from
time to time may issue Class C Limited Partnership Interests to employees of the
Partnership or of any Operating Entity or subsidiary of the Partnership, and
shall fix the right of each such Class C Limited Partnership Interest to receive
distributions pursuant to paragraph 4.2.1(c); provided, however, that in no
                                              --------  -------            
event shall all such Class C Limited Partnership Interests be entitled to
receive more than 3% of the aggregate distributions made pursuant to paragraph
4.2.1(c) (except by reason of any allocation to the Class C Limited Partnership
Interests of all or any part of any "GP Reduction Percentage" (as hereinafter
defined)). The Class C Limited Partnership Interests so issued shall be subject
to such conditions, restrictions and vesting schedules as shall be determined by
the General Partner and approved by the Advisory Committee. The first 1% of the
aggregate distributions made pursuant to paragraph 4.2.1(c) that is allocated to
the Class C Limited Partners pursuant to this paragraph 4.2.2(a)(i) shall result
in a corresponding reduction in the GP Special Allocation Percentage and the
next 2% shall result in a corresponding reduction in the percentage allocated to
the Class A and Class B Limited Partners and the General Partner pursuant to
clause (i) of paragraph 4.2.1(c). By way of illustration, and not of limitation,
if pursuant to this paragraph 4.2.2(a)(i) the Class C Limited Partnership
Interests are allocated 3% of the aggregate distributions made pursuant to
paragraph 4.2.1(c) (i.e., the maximum amount that may be allocated pursuant to
                    ----                                          
this paragraph 4.2.2(a) (i)), then the GP Special Allocation Percentage would be
reduced by 1%, and the resulting GP Special Allocation Percentage would be 6%,
and the percentage allocated to the Class A and Class B Limited Partners and the
General Partner pursuant to clause (i) of paragraph 4.2.1(c) would be reduced by
2%, and the resulting percentage would be 83%.
