business.

3.2 The authorized capital of the Corporation consists of 50,000 shares of
common stock without par value, of which 200 shares have been duly issued and

                              MINERAL ROYALTY DEED

        This mineral royalty deed is made between Britt Minerals, Inc., a
Montana corporation whose address is 921 West Spruce Street, Missoula, Montana
59802 (referred to in this deed as "Britt"), and the following persons
(collectively referred to in this deed as the "Grantees"):

(a)     Peter Ellsworth, whose address is 265 Benton Avenue, Missoula, Montana
        59801, a three-fourths of one percent (0.75%) royalty interest; and

(b)     Garry J. Carlson, whose address is 921 Spruce Street, Missoula, Montana
        59802, a three-fourths of one percent (0.75%) royalty interest.

        FOR VALUE RECEIVED, Britt hereby grants, sells, assigns, transfers, and
conveys to the Grantees, as tenants in common, and to the Grantees' heirs and
assigns, a gross overriding royalty (referred to in this deed as the "Gross
Overriding Royalty"), in the amounts and on the terms and conditions described
in this deed, in all gem and industrial diamonds (referred to in this deed as
"Diamonds") recovered, sorted and graded from the mineral rights located in
________ County, Montana, described below (referred to in this deed as the
"Mineral Rights"):

                            [DESCRIBE MINERAL RIGHTS]

        Each of the Grantees is entitled to receive a Gross Overriding Royalty
which is equal to the percentages specified above of the "Appraised Value" (as
defined in this deed, and reconciled as provided for in this deed) of all
Diamonds recovered, sorted and graded from the Mineral Rights, free and clear of
all costs of development and operation, and subject only to taxes and royalties
(except income taxes) and the fees and expenses of graders as provided for in
this agreement.

        "Appraised Value" means the valuation in American Dollars of the
Diamonds at the minesite determined by an independent grade appointed by Britt.
The independent grader shall be duly qualified and accredited, and shall sort,
grade and value the Diamonds in accordance with industry standards, having
regard to, but without limiting the generality of the foregoing, the commercial
demand for the Diamonds, the grades of the Diamonds (gem or industrial), and the
colors, sizes and clarity of the Diamonds. The independent valuator shall value
each particular classification of the Diamonds in accordance with the industry
pricebooks, standards and formulas.

        The Gross Overriding Royalty will be calculated and paid within 30 days
of the end of each calendar quarter, based on all Diamonds from the Mineral
Rights which were graded in that calendar quarter.

        Within 90 days after Britt has received payment for all Diamonds from
the Mineral Rights which were graded in a calendar years, it will reconcile the
Appraised Value (deducting only taxes, royalties and the fees and expenses of
graders as aforesaid) of all such Diamonds with the actual



                                      -14-


<PAGE>



proceeds received by Britt from the sale of those Diamonds (deducting only
taxes, royalties and the fees and expenses of graders as described above), and
provide to the Grantees a statement showing all pertinent information in
sufficient detail to explain the calculation of the royalty payment. If the
aggregate proceeds (deducting only royalties and the fees and expenses of
graders as described above) are greater than the Appraised Value, Britt will pay
each Grantee its proportionate share of the excess. if the Appraised Value is
greater than the aggregate proceeds (deducting only taxes royalties and the fees
and expenses of graders as described above), then each Grantee will pay to Britt
its proportionate share of the excess.

        All Gross Overriding Royalty payments shall be considered final and in
full satisfaction of all obligations of Britt with respect to those Gross
Overriding Royalties, unless a Grantee gives Britt written notice describing and
setting forth a specific objection to the calculation of the Gross Overriding
Royalty within 12 months after receipt by the Grantee of the statement provided
for above. If the Grantee objects to a particular statement, the Grantee shall,
for a period of 30 days after Britt's receipt of notice of the objection, have
the right upon reasonable notice and at a reasonable time, to have Britt's
accounts and records relating to the calculation of the Gross Overriding Royalty
in question audited by a chartered accountant acceptable to the Grantee and to
Britt. If the audit determines that there has been a deficiency or any excess in
the payment made to the Grantee, the deficiency or excess shall be resolved by
adjusting the next quarterly Gross Overriding Royalty payment due under this
deed. The Grantee shall pay all costs of the audit unless a deficiency of more
than ten percent (10%) of the amount due is determined to exist, in which case
Britt will pay the costs of the audit. All books and records used by Britt for
adjustment in such 12-month period shall establish the correctness and preclude
the filing of exceptions or making of claims for adjustment thereon.

        In addition, if Britt conducts an audit, either internally or by an
independent auditor, of the operations on or in respect of the Mineral Rights,
each of the Grantees will be notified and, at its request, will be provided with
a copy of the portion or portions of such audit which pertain to production
statistics.

        Dated November __, 1999.
