         A.       On or about February 8, 2000, the parties entered into Letter
                  Agreement (the "Agreement").

         B.       The parties hereto desire to amend the Agreement to reflect
                  certain additional compensation to which Rubicon shall be
                  entitled.

         NOW THEREFORE, the parties hereto hereby amend the Agreement as

         1. In light of the fact that the level of services being performed by
Rubicon is greater than originally expected by the parties, Rubicon, in addition
to the compensation set forth in the Agreement, shall be entitled to the
following compensation:

                  (i)      A $25,000 cash fee payable on or before December 15,
                           2000 and;

                  (ii)     The right to designate nominees holding not more than
                           250,000 Series D Warrants which nominees will be
                           entitled to exercise said warrants (as may be amended
                           or improved) on or before January 31, 2001 in
                           exchange for a non-interest bearing promissory
                           note(s) in a form reasonably satisfactory to the
                           Company that are due and payable on July 31, 2001.

                           upon exercise of the Series D Warrants shall bear a
                           legend indicating that the shares are "partially
                           paid;" and

                  (iii)    The right of the nominees designated in (ii) above to
                           benefit from any amended or improved terms offered to
                           holders of Series D Warrants, irrespective of the
                           right to exercise in accordance with (ii) above.

         2. The Agreement shall remain in full force and effect and shall remain
unaltered, except to the extent specifically amended herein.

IN WITNESS WHEREOF, the undersigned, have executed this Amendment No. 1 to the

         RE: Election to Proceed with Additional Pilot Plant

Dear Bill:

Pursuant to our recent discussions, both MCNIC Pipeline & Processing Company
("MCNIC") and Crown Asphalt Corporation ("Crown"), as all of the members of
Crown Asphalt Ridge L.L.C. ("CAR"), have agreed that CAR should proceed with the
construction and operation of the pilot plant for the purposes of assessing the
process modifications made to CAR's tar sands facility in Vernal, Utah. The
purpose of this letter is to set forth the agreement of the parties with regard
to the present funding of the pilot plant without otherwise affecting the
parties' respective rights under the LLC Agreement, as defined below, other than
as expressly set forth herein. The estimated cost of such pilot plant is as set
forth in the Authorization for Expenditure attached hereto as Exhibit A (the
"Pilot Plant AFE"). Both MCNIC and Crown have agreed to and, simultaneously with
the execution of this Letter Agreement will, execute the Pilot Plant AFE. The
Pilot Plant AFE authorizes CAR, or either member on behalf of CAR, to expend the
sums set forth on the Pilot Plant AFE for the benefit of CAR.

While Crown has authorized CAR, or MCNIC on behalf of CAR, to make the
expenditures set forth on the Pilot Plant AFE, Crown, in its capacity as a
member of CAR, has stated that it is not able at this time to make its
proportionate share of the Additional Capital Contributions required in order to
satisfy the payment of any such expenditures in accordance with the Pilot Plant
AFE. Therefore, MCNIC and Crown agree that Crown will be considered a Delinquent
Member solely with regard to its proportionate amount of the Additional Capital
Contributions actually made by MCNIC and expended by CAR for payment of the
amounts under the Pilot Plant AFE. As provided in Section 3.6(a)(ii) of the
Crown Asphalt Ridge L.L.C. Operating Agreement, dated as of August 1, 1997 (the
"LLC Agreement"), MCNIC, as the Non-Defaulting Member, will advance Crown's
proportionate share of the Additional Capital Contributions from time to time
required for the payment of the expenditures set forth on the Pilot Plant AFE,
but shall be deemed not to be in breach of the LLC Agreement as a result of such
status. Such Additional Capital Contributions advanced by MCNIC will be

designated as a Capital Contribution by MCNIC and will be subject to the terms
and conditions of Section 3.6(a)(ii)(B) of the LLC Agreement. As a result, as
provided in Section 3.6(a)(ii)(B), Crown, as the Delinquent Member will have its
Sharing Ratio reduced and MCNIC, as the Non-Defaulting Member will have its
Sharing Ratio increased to reflect the fact that MCNIC has made an Additional
Capital Contribution as agreed by the parties on the Pilot Plant AFE. MCNIC will
provide documentation to Crown evidencing the payment of such Additional Capital
Contribution.

For purposes of this Letter Agreement, terms used but not defined, shall have
the meaning assigned to them in the LLC Agreement. Except as specifically
provided in this Letter Agreement, the LLC Agreement will remain in full force
and effect with no changes, amendments or revisions. If the foregoing accurately
reflects our understanding, please execute both originals in the space provided
below. Please return one original to me and retain the other for your files.

Sincerely,

Crown Asphalt Corporation

         Re:      Additional Costs

Dear Bill:

Crown Asphalt Ridge L.L.C. ("CAR") has incurred the costs set forth in the
attached Exhibit "A" (the "Additional Costs"). Crown Asphalt Corporation
("Crown"), in its capacity as a member of CAR, is not able at this time to
contribute its proportionate share of the Additional Costs. Crown understands it
will be considered a Delinquent Member solely with regard to its proportionate
amount of Additional Capital Contributions actually used to pay the Additional
Costs, but shall not be deemed to be in breach of the LLC Agreement, as defined
below, as a result of such status. MCNIC agrees, as the Non-Defaulting Member,
to advance Crown's proportionate share of the Additional Costs as provided in
Section 3.6(a)(ii) of the CAR Operating Agreement, dated as of August 1, 1997
(the "LLC Agreement"). The Additional Capital Contributions advanced to CAR by
MCNIC will be designated as a Capital Contribution and will be subject to the
terms and conditions of Section 3.6(a)(ii)(B) of the LLC Agreement. As a result,
as provided in Section 3.6(a)(ii)(B), Crown, as the Delinquent Member, will have
its Sharing Ratio reduced and MCNIC, as the Non-Defaulting Member, will have its
Sharing Ratio increased to reflect the fact that MCNIC has made the Additional
Capital Contributions as agreed by the parties as reflected on Exhibit "A".
Terms not specifically defined within this Letter shall have those meanings
given them by the LLC Agreement.

Sincerely,

/s/ Jay Mealey

         Re:  Agreement to Purchase Property

Gentlemen:

         This letter, when executed by you and returned to the undersigned,
shall evidence the Agreement between Refinery Technologies, Inc. ("RTI") and
Crown Asphalt Products Company ("CAPCO") for the assignment of certain leases
and the sale of certain real property as described in Exhibit "A" attached
hereto (the "Property"). CAPCO desires to purchase, and RTI desires to sell, the
Property, including the building, fixtures and improvements thereon, located at
the south end of the Cowboy Asphalt Terminal ("CAT") property, except the
property known as the Cardlock Service Station, as more fully described in the
Exhibit "B" attached hereto (the "Cardlock Property") consisting of less than
two acres alone 2561 South at approximately 1560 West in Woods Cross, Utah.

         1.       The purchase price to be paid by CAPCO to RTI for the property
                  is $280,750.00 ("Purchase Price").

         2.       CAPCO will pay RTI a down payment of $16,000 at Closing (the
                  "Down Payment"), and will execute a Promissory Note and Trust
                  Deed for the balance of the balance of the Purchase Price. The
                  Promissory Note will provide for interest at eight percent
                  (8%) per annum and will have a ten (10) year term, with the
                  principal and interest payments made to RTI on a monthly
                  basis.

         3.       RTI will execute and deliver to CAPCO a Quit Claim Deed
                  transferring to CAPCO the Property described in Exhibit "A"
                  located at the south end of the CAT property.

         4.       Closing will be effective as of November 17, 2000.

         5.       RTI will prepare the formal agreements evidencing this
                  transaction. Both RTI and CAPCO will use their best efforts to
                  negotiate the formal agreements in good faith and to complete
                  the transaction by such Closing.

         6.       All leases, agreements and rents currently related to the
                  Property which have not previously been assigned to CAT other

Page 2

                  than as set forth below, will be assigned to CAPCO effective
                  at Closing. RTI will provide the necessary assistance in
                  effecting such transfer.

         7.       This Agreement and the Assignment of Leases shall not affect
                  RTI's interest as Lessor in the Lease to Genesis Petroleum
                  ("Genesis Lease"), or in any extension or renewal thereof, as
                  more fully described on Exhibit "D" to the Assignment and
                  Agreement dated September 11, 1998 (the "Assignment and
                  Agreement").

         8.       This Agreement is not subject to RTI holding clear title to
                  the Property. The Property is subject to a Deed of Trust given
                  by CAT as Trustor to Hancock/Geisler. CAT is the record title
                  holder of the CAT property, including the property which is
                  the subject of this Letter Agreement, and has held such title
                  since approximately January 7, 1999. CAT has not deeded the
                  Property to RTI as contemplated by RTI's interest in the
                  Property is set forth in the Assignment and Agreement.

         9.       Upon a dissolution of CAT, RTI will retain the right to the
                  distribution of CAT's assets as provided for in Paragraph 5 of
                  the Assignment and Agreement.

         10.      In the event CAT elects to sell the Property and CAPCO does
                  not exercise its right to purchase as provided in Paragraph 6
                  of the Assignment and Agreement, which right is assigned to
                  CACPO hereunder, CAPCO will immediately offer such right to
                  purchase to RTI.

         11.      In the event the members of CAT desire to withdraw from CAT
                  and, (i) the other member does not exercise its right to
                  purchase the withdrawing member's units of membership
                  interests in CAT; and (ii) thereafter CAPCO does not elect to
                  acquire such interest as provided for in Paragraph 7 of the
                  Assignment and Assumption, which right is assigned to CAPCO
                  hereunder; CAPCO will immediately offer such right to acquire
                  the units of membership in CAT to RTI.

         Please evidence the acceptance of the foregoing terms and conditions by
RTI with the execution in the space provided below.

                                                 Sincerely,

                                                 REFINERY TECHNOLOGIES, INC.

                                                 Mark E. McSwain, VP President
