       COLUMBIA PROPANE TO ACQUIRE NATIONAL PROPANE FOR $12.00 IN CASH
                                PER COMMON UNIT

Richmond, VA and Cedar Rapids, IA, April 5, 1999 -- Columbia Propane Corporation
(Columbia  Propane),  a subsidiary  of Columbia  Energy  Group  (NYSE:  CG), and
National  Propane  Partners,  L.P.  (NYSE:  NPL) announced  today that they have
signed a definitive  purchase agreement whereby Columbia Propane will commence a
tender offer to acquire all of the approximately 6.7 million  outstanding common
units of  National  Propane for $12.00 in cash per common  unit.  Subject to the
terms and conditions of the agreement,  Columbia  Propane would also acquire the
general partner  interests and  subordinated  unit interests of National Propane
from  subsidiaries of Triarc Companies,  Inc. (NYSE:  TRY).  Approximately  $141
million  of  National  Propane's  outstanding  indebtedness  is  expected  to be
refinanced by Columbia Propane in connection with the transaction.

        The proposed acquisition of National Propane would add more than 210,000
retail and  wholesale  customers  in 24  states,  extending  Columbia  Propane's
presence  from the  Mid-Atlantic  and  Northeast to the  Southeast,  Midwest and
Western  regions of the United  States.  The  combination  would also  result in
Columbia Propane having more than 300,000 customers with operations in 35 states
and the District of Columbia.

        "With today's announcement,  Columbia Propane is aggressively  executing
part of the Group's  nonregulated  growth strategy," said Oliver G. Richard III,
Chairman,  President and CEO, of Columbia  Energy Group.  "The National  Propane
acquisition  gives  Columbia  Propane the  opportunity to triple the size of its
customer base, and rank among America's leading propane companies."

        Ronald R. Rominiecki,  President and Chief Operating Officer of National
Propane,  said: "The Columbia  Propane  transaction will  significantly  improve
National Propane's growth prospects. At a significant premium to today's closing
market price, the Columbia Propane acquisition is a very attractive  transaction
for our common unitholders which our Board fully supports."







        The Board of Directors of National  Propane's  managing general partner,
acting on the recommendation of its Special Committee,  has unanimously approved
the Columbia  Propane  transaction and unanimously  recommended that unitholders
tender their common units pursuant to the offer. The Special Committee  received
an  opinion  of  Lehman  Brothers  that,  from a  financial  point of view,  the
consideration  to  be  received  by  the  common  unitholders  in  the  proposed
transaction is fair to the common unitholders.

        The tender offer is the first step of a two-step  cash  transaction.  In
the second step,  subject to the terms and conditions of the purchase  agreement
among the  parties,  Columbia  Propane  would  indirectly  acquire  the  general
partnership  interests and subordinated  unit interests of National Propane from
subsidiaries of Triarc and National  Propane would merge into Columbia  Propane,
L.P.

        As part of the second step, any remaining common unitholders of National
Propane  would  receive,  in  cash,  the same  per  unit  price as that  paid to
unitholders who tender their shares  pursuant to the tender offer.  Triarc would
receive  approximately  $17.9  million for its  acquired  interests  in National
Propane - $2.1  million  in cash and $15.8  million  payable  in the form of the
forgiveness of indebtedness owed by Triarc to National Propane.  Simultaneously,
and as a  condition  of the  closing,  Triarc will  prepay  approximately  $14.9
million of such indebtedness.

        The  managing  general  partner of National  Propane has also agreed to,
among other things,  execute a consent, as holder of all the subordinated units,
to approve the merger and other transactions contemplated by the agreement.

        Columbia  Propane,  through  its direct  and  indirect  subsidiaries  CP
Holdings,  Inc. and Columbia Propane,  L.P., intends to commence its cash tender
offer for all of the outstanding  common units of National Propane at a price of
$12.00 per unit, net to the seller in cash,  beginning  April 9, 1999. The offer
for the common  units will be subject  to certain  conditions,  including  there
being validly  tendered by the expiration  date,  and not withdrawn,  at least a
majority of the outstanding common units on a fully diluted basis.

        The offer will be made only upon and subject to the terms and conditions
of the Offer to Purchase and the related Letter of Transmittal.

        National  Propane  Partners,  L.P. has  operations  concentrated  in the
Midwest,  Northeast,  Southeast  and  Western  regions of the United  States and
serves over 210,000 active customers  through its 155 full service  centers.  In
1998, National Propane sold more than 144 million gallons of propane.

        Columbia  Propane has been a full-service  propane  supplier since 1941.
Columbia  Propane is an operating  company of Columbia  Energy  Group.  Columbia
