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

     THAT, WHEREAS, Licensor purchased from Licensee the design of a certain gas
heater for use in outdoor applications (the "Patio Heater") which is the subject
of a applications for patents with the United States Patent & Trademark Office
which are listed on Schedule A; and

     WHEREAS, pursuant to the Asset Purchase Agreement dated as of March 31,
1999, among International Propane Products, LLC ("IPP"), and Licensee, as
Seller, and Licensor, as Buyer (the "Purchase Agreement"), the Licensor has
agreed to execute and deliver this Agreement; and

     WHEREAS, Licensor has the right to grant licenses to make, use and vend
Patio Heater and trade secret technology related to the production of Patio
Heater, including the technology disclosed in the patent application and any
related technology developed by Licensor hereafter (the "Trade Secret
Technology"); and

     WHEREAS, Licensee desires to acquire from Licensor a license to make, use
and vend the Patio Heater and the Trade Secret Technology upon the terms and
conditions herein set forth; and

     NOW, THEREFORE, in consideration of the mutual promises contained herein,
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, each of the parties hereto agree as follows:

     1.  Grant of License. After the occurrence of a Deficiency Event unless
sooner terminated or modified as hereinafter provided, for a period during which
a patent covering the Patio Heater provides to Licensor the exclusive right to
make, use and vend the Patio Heater (the "Term"), Licensor hereby grants to
Licensee the right and license (A) to manufacture, have manufactured, import,
use and sell the Patio Heater throughout the United States, its territories,
Canada and Mexico (the "Territory") and (B) to use the Trade Secret Technology
for the sole purpose of manufacturing, having manufactured, using, and selling
the Patio Heater in the Territory. Licensor agrees to apply for patents in the
Territory and to maintain the patents during the Term.

     2.  Power to Sublicense. Licensor hereby grants Licensee the right and
power, After the occurrence of any Deficiency Event, (as hereinafter defined),
to issue sublicenses to manufacture inside or outside of the Territory and sell
the Patio Heater throughout the
<PAGE>

Territory and to disclose the Trade Secret Technology to such sublicensees
during the Term, provided, however, that Licensee requires any such sublicensee,
pursuant to a written agreement, to maintain the confidentiality of the Trade
Secret Technology and use the Trade Secret Technology solely for the purpose of
manufacturing the Patio Heater. Any such sublicense may be for all or any
portion of the Territory and for all or less than the Term. Licensee shall
promptly give reasonable notice to Licensor of any such sublicense and its basic
terms and promptly provide Licensor with copies of any and all agreements
relating thereto. As used herein a "Deficiency Event" is the first to occur of
either (a) the failure of Blue Rhino to pay Deferred Purchase Price in the
amount of the minimum required pursuant to the Purchase Agreement within thirty
(30) days after notice from Waters that the same is due and payable or (b) the
end of the Deferred Payment Term (as defined in the Purchase Agreement).

     3.  Royalties. In consideration of the license granted in this Agreement,
Licensee agrees to pay to Licensor royalties ("Royalties") derived from sales of
the Patio Heaters, whether by Licensee or by sublicensees, as hereinafter
provided. The Royalties shall be one percent 1% of Net Sales as defined in the
calculation of the Deferred Purchase Price under the Purchase Agreement except
that Net Sales does not include sales to or at the direction of Licensor.

Licensee shall pay Licensor royalties pursuant hereto within thirty (30) days of
the close of each and every calendar quarter of the Term, except that Licensee
shall pay Licensor royalties for the last quarter of the year within ninety (90)
days of the close of each and every calendar year of the Term, at which time
adjustments, if any, to Net Profit and royalties will be made based on fiscal
year end audited financial statements of the Licensee or, if audited financial
statements are not prepared by an independent accountant, on the reviewed or
compiled financial statements of the Licensee or its sublicensees. Licensee's
royalty payments to Licensor shall be accompanied by a royalty report setting
forth sales of the Patio Heater Net Sales for the appropriate period(s).
Licensee will keep records showing the products sold or otherwise disposed of
during the Term of this Agreement in such detail as to enable the amounts
payable hereunder to be easily determined. Licensee shall also permit its books
and records to be examined by Licensor up to twice annually to the extent
necessary to verify the sales, Gross Profit, Fair Market Value, Cost of Good
Sold, and royalty payments provided for herein. Such examination shall be made
during normal business hours, at times convenient to Licensor and Licensee. In
the event that such examination reveals an underpayment in the Royalties of more
than 5%, Licensee shall pay Licensors' costs for such examination.

     4.  No Duty to Exploit the Technology. During the Term the Licensee shall
have no duty to promote the sale and use of the Patio Heater or to sublicense
any manufacturer to manufacture the Patio Heater.

     5.  Infringement. In the event it appears that one or more third parties
are infringing any right of Licensor, Licensee shall notify Licensor of such
apparent infringement. Licensor, after notice thereof to Licensee, may
immediately commence and

                                       2
<PAGE>

prosecute all legal proceedings necessary to prevent such infringement and shall
be responsible for all costs relating to such legal proceedings. Licensee agrees
to cooperate with the Licensor in connection with any infringement matters. Any
payment by an infringer made in settlement of or by way of judgment or award or
otherwise shall belong to Licensor. If Licensor fails to prevent any such
infringement, Licensee may at its sole option and upon written notice to
Licensor, immediately commence and prosecute, at its cost and expense, all legal
proceedings necessary to prevent such infringement itself in the name of
Licensor. In any such action Licensor shall cooperate with Licensee and may
participate at Licensor's expense. Any payment by an infringer made in
settlement of or by way of judgment or award or otherwise shall belong to
Licensee.

     6.  Confidentiality. Licensee acknowledges and agrees that (a) Licensor has
expended significant money to purchase and maintain the secrecy of the Trade
Secret Technology, and (b) if the Trade Secret Technology were disclosed to
another person or entity contrary to this Agreement or used for the benefit of
anyone other than Licensor or Licensee, Licensor would suffer irreparable harm,
loss and damage. Accordingly, Licensee acknowledges and agrees that, unless the
Trade Secret Technology becomes publicly known through legitimate origins:

     1)   the Trade Secret Technology is, and at all times hereafter shall
          remain, the sole property of Licensor; and

     2)   except as otherwise specifically permitted by this Agreement with
          respect to sublicensees, Licensee shall use its best efforts and the
          utmost diligence to guard and protect the Trade Secret Technology from
          any unauthorized use or disclosure to any other person or other
          entity.

Licensee also acknowledges and agrees that all documentary and tangible Trade
Secret Technology is supplied or made available by Licensor to Licensee solely
for the purposes of the license granted herein. Licensee further agrees that if
the Term of the licensee granted herein terminates or is terminated at any time
for any reason, Licensee and its sublicensees shall immediately return to
Licensor all documentary and/or tangible Trade Secret Technology in their
possession, custody, or control and not make or keep any copies, notes,
abstracts, summaries, tapes or other record of any type of Trade Secret
Technology.

     7.  Default.  Should a party to this Agreement consider the other party to
be in breach of this Agreement, it shall notify the breaching part as to the
breach. The breaching party shall have thirty (30) days from the notice to
correct the breach and give notice of the correction to the non-breaching party.
Should, after the thirty (30) day period following the notice of breach, the
breach not be corrected, the non-breaching party may notify the breaching party
that the Agreement is terminated, and the Agreement shall be terminated.
Notwithstanding anything to the contrary set forth herein, if the default is of
such a nature that cure commenced during such thirty day period cannot be
completed within such period, this agreement may not be terminated so long as
cure is commenced during such thirty day period and completed within one hundred
and twenty days thereafter.

Agreement shall be indivisible and shall not be transferable without the
