(the "Royalty Holders"), and with the consent of Hendricks Mining Co. a/k/a

         WHEREAS, Hendricks and Royalty Holders have previously been parties to

         WHEREAS, CRCI is acquiring the assets of Hendricks in a reorganization;
and

         WHEREAS, the parties have agreed to further clarify the terms of the
Prior Grants and to modify the Prior Grants as to specific terms in connection
with the further grant by CRCI of the royalty interests described herein; and

         WHEREAS, Hendricks and CRCI wish to clarify the assumption by CRCI of
the obligation to make royalty payments as the same may become due by virtue of
its acquisition of the property titles of Hendricks and subsequent production,
if any, from the Properties names here and in the Prior Grants;

         NOW, THEREFORE, for and in consideration of other good and valuable
consideration, the receipt of which is hereby acknowledged and confirmed by
CRCI, CRCI does, for itself, its successors and assigns, hereby grant to the
Royalty Holders (in the percentage interests set forth below) a 2% Net Smelter
Return Royalty Interest (the "Royalty") applicable to ores and minerals mined
from the properties listed on Exhibit A attached hereto (the "Properties"), on
the following terms:

         1.       Grant of Royalty.

         The Royalty shall be two percent (2.0%) of Net Smelter Returns from the
ores, minerals, concentrates or dore ("Material") mined from the Properties and
sold or distributed.

         The Royalty shall be distributed in the following percentages, or
otherwise as the Royalty Holders shall direct:

                  Thomas S. Hendricks                85.354% of 2.0%
                  Marjorie J. Hendricks              10.101% of 2.0%
                  John R. Henderson                   4.545% of 2.0%

         2.       Term of Royalty Grants.

         The term of the Royalty Interest shall be twenty (20) years from the
date hereof, and shall apply to Material mined from the Properties (whether or
not sold or distributed) on or prior to the termination date.

         3.       Definitions.

         "Net Smelter Returns" as used herein shall mean the gross revenues
received by CRCI for all Material produced and sold from the Properties less
only the actual costs of sale, insurance, smelting or refining and the cost of
transportation to the smelter or refinery or other arms length purchaser. For
the purpose of this section, "actual costs of smelting or refining" shall be
defined as excluding the costs of mining, milling, heap or other leaching and/or
in-situ processing.

                                        2
<PAGE>

         If CRCI elects to forward sell gold and/or silver, the Royalty shall
not be determined by the forward sale price. Instead, the Royalty shall be
determined based upon the actual arm's length sale price of gold and silver or
in the case of delivery of metal pursuant to a forward sale contract, by Imputed
Gross Revenues. "Imputed Gross Revenues" received by CRCI for such gold and/or
silver shall be deemed to be the spot price as quoted by the London PM fixing
for gold and the Handy and Harman, New York price for and silver on the date the
gold and silver is delivered ("Other Delivery") by CRCI under a forward sale
contract or the date upon which CRCI makes a distribution. The Royalty will be
calculated by deducting the allowable deductible costs set forth above from the
Imputed Gross Revenues deemed to have been received by CRCI.

         4.       Time for Payment of Royalty.

         The Interest herein granted shall be paid to the Royalty Holders during
the next calendar month succeeding the calendar month in which sales proceeds
are realized or in which distribution to working or other interest holders, or
Other Delivery, is made, such payment to be accompanied by a detailed smelter or
other sale settlement sheet together with a copy in suitable detail of the
calculation used in determining the royalty payment. If Material is distributed
(a "Distribution") rather than sold to an arm's length purchaser, the Royalty
shall be calculated and paid by CRCI to the Royalty Holders as though Materials
produced and sold from the Properties had been sold to a smelter, refinery or
other purchaser by CRCI in an arm's length transaction, meaning that CRCI shall
determine what its Imputed Gross Revenues would have been had the Material been
sold in an arm's length transaction. CRCI then shall deduct from the Imputed
Gross Revenue figure the costs and charges referred to in Section 3. All royalty
payments made to the Royalty Holders pursuant to this Section 4 shall be
accompanied by a statement showing how the royalty interest payment was
calculated. If the parties disagree, the matter shall be resolved in accordance
with the Commercial Arbitration Rules of the American Arbitration Association in
Denver, Colorado.

         5.       Tax Matters.

         The Royalty Holders, by accepting the Grant, hereby agree to pay any
tax, including any metalliferous production tax or severance tax (now existing
or enacted in the future) applicable to their two percent (2.0%) Royalty as the
same is defined herein. Each party shall be individually responsible for payment
of its own taxes upon income, whether State, Federal or local in nature.

         6.       Intent of Parties.

         In addition to the Grant evidenced by this Agreement, this Grant shall
also constitute:

                  a.       A contract between CRCI and the Royalty Holders,
                           their respective successors and assigns, to pay the
                           Royalty Interest as and when due; and

                                        3
<PAGE>

                  b.       A mutual covenant running with the Properties
                           expiring upon the termination date provided inss.2
                           above.

         In the event that any court of competent jurisdiction should find,
after any period for appeal has expired, that the Royalty granted herein is,
instead, a grant of an undivided two percent (2.0%) interest in the Properties
(which the parties do not intend), then and only then such interest shall be
deemed to be leased to CRCI, as the case may be, for the twenty (20) year term,
at a lease royalty rate equivalent to one hundred percent (100%) of gross
revenues attributable to the two percent (2%) interest, less an equivalent
percentage of deductible costs as defined above, to be paid in the manner
provided herein as and when due.

         Such lease would terminate on the twenty (20) year anniversary date
hereof subject only to accounting for ores previously severed, and title to
CRCI's interest in the Properties would be deemed to revest in CRCI, as the case
may be, or its successor in title to the Properties.

         7.       Continued Application of Grant.

         This Grant shall continue to apply to any amendment, relocation or new
location of any unpatented mining claims listed in Exhibit A or in the Prior
Grants (or, if the 1872 Mining Act be changed, to any new or successor interest
as may be established or provided for under any successor law, including, but
not limited to, a conversion or relocation of the unpatented claims) or, if
applicable, after the grant of a mineral patent or patents. In the event that a
successor interest is created, CRCI agrees to evidence this grant in the form of
a new recordable writing applicable to the new or successor interest.

         8.       Place of Payment.

         Unless directed otherwise in writing by the Royalty Holders, CRCI's
payment obligations hereunder shall be deemed satisfied by making such payments
as are required hereunder to any bank account which may be jointly designated by
the Royalty Holders, or by making payment to their last known address, which
Royalty Holders shall supply to CRCI as the same may change. With each royalty
payment, CRCI shall supply the Royalty Holders with originals or copies of
originals of the settlement documentation.

         9.       Right of First Refusal to CRCI.

         If the Royalty Holders receive a bona fide offer which they are willing
to accept for the Royalty or any part thereof or negotiates the sale of their
Royalty or any part thereof within its term, the Royalty Holders shall
immediately give written notice thereof to CRCI. The notice shall include a
disclosure of the prospective purchaser's identity, address and telephone
numbers and shall specify the price of the interest being sold or disposed of
and all other terms and conditions of the offer, including a description of any
non-cash consideration and its estimated cash value. If the parties disagree as
to the cash value of any such non-cash consideration, the matter shall be
resolved in accordance with the Commercial Arbitration Rules of the American
Arbitration Association in Denver, Colorado. For a period of thirty (30) days
following receipt

                                        4
<PAGE>

of such notice or the determination of arbitration of the cash value of any
non-cash consideration included in the notice, whichever is later, CRCI shall
have the first right or option to acquire the Royalty or the part thereof being
sold or disposed of by the Royalty Holders upon the terms stated in the notice.
The first right or option of CRCI to acquire the Royalty or interest therein
being sold or disposed of by the Royalty Holders shall be exercised by written
notice to the Royalty Holder within thirty (30) days from the effective date of
the original notice to CRCI or from an arbitrator's decision on the cash value
of any non-cash consideration included in the offer or such first right or
option shall terminate. If CRCI exercises its option, closing of the acquisition
shall take place within ten (10) days following the date of the exercise of the
option which shall be the date that written notice of exercise is delivered to
Royalty Holders. The Royalty Holders shall execute an assignment of the Royalty
or part thereof being sold or disposed of by the Royalty Holders to CRCI which
shall contain a special warranty that the interest being assigned is free and
clear of all liens, claims, clouds and encumbrances arising by, through or under
the Royalty Holders. At closing, CRCI shall deliver to the Royalty Holders the
cash consideration (including the estimated value of any non-cash consideration)
for the interest being acquired by CRCI by cashier's check or certified funds.

         If CRCI fails to exercise its option as herein provided, the Royalty
Holders may accept the bona fide offer extended to them or close the transaction
they negotiated for the disposal of their Royalty or part thereof subject to
being sold or disposed of; provided, however, that the Royalty Holders may not
dispose of their interest for a consideration less favorable to them than the
terms specified in the original notice given to CRCI hereunder and provided,
further, that if the Royalty Holders have not completed the sale of their
interest, or the portion thereof set forth in the notice, within sixty (60) days
following the expiration of the thirty (30) day refusal period provided above,
the provisions of this right of refusal shall again become effective.

         10.      Partial Buyout Option to CRCI.

         CRCI shall have the right and option to elect to purchase one-half
(1/2) of the Royalty (or a maximum 1% Net Smelter Return Royalty out of the 2%
Royalty granted) from the Royalty Holders at any time during its term for the
option price of Seven Hundred Fifty Thousand Dollars U.S. in cash ($750,000.00)
("Buyout Option"). The remaining 1% Net Smelter Return Royalty is subject to
buyout only upon further written agreement of all parties. Upon CRCI's informing
the Royalty Holders of its written election to purchase, there shall be created
an agreement for the Royalty Holders to sell, and for CRCI to purchase, the
Royalty.

         Closing shall be held at 1720 14th Street, Suite 200, in Boulder,
Colorado or at such other location within Boulder, Colorado, as may be
designated by Royalty Holders, on the 15th business day following the date of
receipt of the written notice. The transfer shall be by Bargain and Sale Deed.

         The parties agree that the value of the Royalty is highly speculative;
Royalty Holders, for their part, agree that the grant of the Buyout Option is
absolute, and that the Buyout Option may be exercised at any time during its
term, including in the event that minerals in commercial quantities are
discovered on the Properties. For the purposes of clarity, the giving of notice
of

                                        5
<PAGE>

exercise of the Buyout Option shall be the cutoff date for accounting for
Material upon which payment to the Royalty Holders of the Royalty may be due and
owing as of the date of Closing, being all Material which has been sold or
distributed as of that date.

         11.      Modification of Prior Grants.

         CRCI, Hendricks and the Royalty Holders hereby jointly agree to the
following modifications to the Prior Grants :

                  a.       Hendricks hereby assigns to CRCI all of its right,
                           title and interest in and to any right of first
                           refusal and the buyout rights granted or reserved in
                           the Prior Grants to Hendricks. Effective this date,
                           CRCI shall hold the full right, title and interest in
                           and to the rights of first refusal and buyout rights,
                           including any contained Buyout Option, contained in
                           the Prior Grants, and Hendricks shall have no further
                           interest therein.

                  b.       The Buyout Option contained inss.10, above, shall,
                           without any increase in the purchase price, apply to
                           the royalty interests granted to the Royalty Holders
                           in the Prior Grants. The Purchase Price for the
                           Buyout Option contained in this grant, the Prior
                           Grants, and any future grants pursuant to this
                           instrument, shall henceforth be U.S. $750,000.00 for
                           one-half of the Net Smelter Return Royalty, being a
                           maximum 1.0% out of the 2.0% grant. The buyout right
                           to purchase the Royalty Interest in its entirety is
                           hereby eliminated from the Prior Grants, absent the
                           further signed, written agreement of the parties. The
                           Prior Grants are hereby modified to eliminate the
                           right or option to purchase, without the Royalty
                           Holders' further written consent, the entire Royalty.

                  c.       The royalty grant of one percent (1%) of Net Smelter
                           Returns contained in the Grant of Royalty Interest
                           for Fixed Term dated October 21,1993 and the First
                           Modification of Royalty Interest for Fixed Term dated
                           October 21, 1993 is hereby increased from one percent
                           (1%) to two percent (2%) of Net Smelter Returns. CRCI
                           hereby bargains, sells, conveys and grants such
                           additional royalty to Royalty Holders as to those
                           properties named in the two referenced Prior Grants.

                  d.       The term of the royalty grant contained in the Prior
                           Grants is hereby extended as follows:

                                    The term of the royalty interest granted
                                    herein and in the Prior Grants is hereby
                                    modified to be twenty (20) years from the
                                    date hereof, being March ____, 1998 to 11:59
                                    p.m. on March ____, 2018, and shall apply to
                                    all Material mined from the

                                        6
<PAGE>

                                    Properties (whether or not sold or
                                    distributed) on or prior to the time and
                                    date of termination.

                  e.       Exhibit B to the Grant of Royalty Interest for Fixed
                           Term recorded at Film 1796, R.N. 1262619 is hereby
                           stricken, and is of no further force and effect. The
                           obligation of CRCI to make future royalty grants
                           based upon acquisitions within the area of interest
                           established in Section 12, below, shall be determined
                           solely by the terms of Sections 11 and 12 herein. The
                           parties hereto state that it is not, and was not,
                           their intent to claim any right, title or interest in
                           and to properties to which Hendricks or CRCI do not,
                           or did not, actually acquire record title.

                  f.       The obligation to make further or future royalty
                           grants based upon an acquisition by CRCI within the
                           area of interest shall be limited as follows:

                           To the extent that any acquired property is already
                           burdened (by grant, reservation, or otherwise) with
                           an existing royalty interest, the Royalty Holders
                           shall be entitled to receive a royalty grant only to
                           the extent that the existing royalty interest is less
                           than 2.0% of Net Smelter Returns, and then only as to
                           the difference between the existing royalty and 2.0%.
                           To the extent that the existing royalty interest in
                           an acquired property equals or exceeds 2.0% of Net
                           Smelter Returns, the Royalty Holders shall receive no
                           further Royalty as to that property, claim or group
                           of claims. In the event that the underlying royalties
                           are terminated by their terms, reduced or otherwise
                           merged or extinguished, Royalty Holders shall receive
                           their royalty share to the extent that the total of
                           royalties then applicable does not exceed 2.0% of Net
                           Smelter Returns.

                  g.       To the extent that CRCI acquires an interest in any
                           property which is less than the whole or undivided
                           mineral estate, the total amount of royalty payable
                           from production from, such a fractional interest
                           shall be obtained by multiplying the royalty interest
                           (i.e., 2.0% of Net Smelter Returns) by the fractional
                           interest acquired (for example only, 50.0% or 112,
                           being the interest acquired) to obtain the percentage
                           of Net Smelter Returns payable from the entirety. The
                           parties agree to apply this manner of calculation to
                           any fractional or undivided interest contained or
                           listed in the Prior Grants.

                  h.       With regard to the Prior Grants, certain claims,
                           including specifically the Anaconda and Lafayette
                           claims, M.S. 12934; Bob Tail M.S. 13180; Broken Bow
                           M.S. 13146; Garfield M.S. 522; Chief and Monticello
                           lodes, M.S. 15637; and Ponderosa lode M.S. 13172, may
                           have been subject to royalty reservations in favor of
                           others ("underlying royalties") prior to the
                           execution of the Prior Grants. The parties agree that
                           no royalty shall be

                                        7

                           payable to the Royalty Holders under the Prior Grants
                           as to these properties at any time during the term
                           hereof when the underlying royalties equal or exceed
                           2.0% of Net Smelter Returns. In the event that the
                           underlying royalties are terminated by their terms,
                           reduced or otherwise merged or extinguished, Royalty
                           Holders shall receive their royalty share to the
                           extent that the total of royalties then applicable
                           does not exceed 2.0% of Net Smelter Returns.

                           CRCI has also acquired the Conger lode mining claim,
                           M.S. 94A, and the Enterprise lode mining claim, M.S.
                           19828, both of which were subject to prior royalty
                           reservations in favor of previous owners ("additional
                           underlying royalties"). Because such additional
                           underlying royalties are equal to or exceed 2.0% of
                           Net Smelter Returns, Royalty Holders are not
                           currently eligible under the terms hereof to receive
                           royalty payments therefrom in the event of
                           production. If, however, such additional underlying
                           royalties are terminated by their terms, reduced, or
                           otherwise merged or extinguished (in any manner which
                           reduces the prior underlying royalty burden below
                           2.0% of Net Smelter Returns) within the twenty (20)
                           years following the date of this agreement, CRCI
                           covenants at such time to execute a royalty grant in
                           favor of Royalty Holders as to those properties, for
                           a royalty term of 20 years, of the difference between
                           the reduced royalty burden and 2.0% of Net Smelter
                           Returns. This covenant shall apply to and shall bind
                           CRCI, its successors and assigns to title to the
                           named properties.

         12.      Covenant to Execute Future Royalty Grants as to Certain
                  Acquired Properties.

         CRCI covenants to execute additional royalty grants upon any properties
which it acquires within the next five (5) years (including properties acquired
by location, deed, lease or under any mining law which may in the future become
applicable to the public lands of the United States), which properties lie in
whole or part within a two mile radius of survey corner number 4 of the Cross
Mill Site Claim, Mineral Survey 20681 B, located in Section 9, Township 1 South,
Range 73 West, 6th P.M., Boulder County, Colorado. Such grant shall be in the
amount of two percent (2.0%) of Net Smelter Returns from Materials mined from
the acquired properties and sold or distributed from the date of acquisition to
the date 20 years after the date of acquisition, at which point the royalty
shall re-vest in CRCI, as the title may be held, or their successor in title.

         The additional royalty grant (and the covenant to make additional
grants) shall be subject to the Buyout Option provided for above with no
increase in the stated purchase price. This covenant shall further constitute a
contract to pay the stated royalty to the Royalty Holders in the stated amount
from the date of acquisition through the 20 year period; CRCI covenants to
inform any future purchaser of the CRCI properties, as title may be held, of the
existence of this Grant and Agreement, and to cause such purchaser to agree to
abide by its terms.

                                        8
<PAGE>

         CRCI shall notify the Royalty Holders in writing within thirty (30)
days after its acquisition of a property as to which the Royalty Holders are
eligible for a further royalty grant pursuant to the terms of Section 11 herein.

         13.      Binding Effect of Royalty Grant.

         When executed, this Grant shall inure to the benefit of, and shall be
binding upon, the parties hereto, their heirs, successors and assigns, and in
the case of CRCI and AAI, to their successors in title to the Properties.

         Dated as of the date first above written.

         ("material") produced and sold from the properties less only the actual
         costs of sale, insurance, smelting or refining and the cost of
         transportation to the smelter or refinery or other arms length
         purchaser. For the purpose of this section "actual costs of smelting or
         refining" shall be defined as excluding the costs of mining, milling,
         heap or other leaching and/or in-situ processing. If HMC elects to
         forward sell gold and silver, Gross Revenues received by HMC for such
         gold and silver shall be deemed to be the spot price as quoted by the
         London PM fixing for gold and silver on the date the gold and silver is
         delivered by HMC to the purchaser. The net smelter return royalty will
         be calculated by deducting the costs set forth above from the Gross
         Revenues deemed to have been received by HMC.

4.       The Royalty Interest herein granted shall be paid to the Royalty
         Holders during the next calendar month succeeding the calendar month in
         which sales proceeds are realized or in which distribution to working
         or other interest holders is made, such payment to be accompanied by a
         detailed smelter or other sale settlement sheet together with a copy in
         suitable detail of the calculation used in determining the royalty
         payment. If material is distributed (a "distribution" ), rather than
         sold to an arm's length purchaser, the Royalty Holders' Net Smelter
         Return Royalty shall be calculated and paid by HMC to the Royalty
         Holders as though materials produced and sold from the Properties had
         been sold to a smelter, refinery or other purchaser by HMC in an arm's
         length transaction meaning that HMC shall determine what its gross
         revenues would have been had the material been sold in an arm's length
         transaction. HMC then shall deduct from the deemed gross revenue figure
         the costs and charges referred to in paragraph 3. All royalty payments
         made to the Royalty Holders pursuant to this paragraph 4 shall be
         accompanied by a statement showing how the royalty interest payment was
         calculated. If the parties disagree, the matter shall be resolved in
         accordance with the Commercial Arbitration Rules of the American
         Arbitration Association in Denver, Colorado.

5.       The Royalty Holders, by accepting the Grant, hereby agree to pay any
         tax, including any metalliferous production tax or severance tax (now
         existing or enacted in the future) applicable to its two percent (2%)
         Royalty Interest as the same is defined herein. Each party shall be
         individually responsible for payment of its own taxes upon income,
         whether State, Federal or local in nature.

6.       In addition to the Grant evidenced by this Agreement, this Grant shall
         also constitute:

         a.       A contract between HMC and the Royalty Holders, their
                  respective successors and assigns, to pay the Royalty Interest
                  as and when due; and

<PAGE>

         b.       A mutual covenant running with the Properties expiring upon
                  the termination date provided in Section 2 above.

         In the event that any court of competent jurisdiction should find,
         after any period for appeal has expired, that the Royalty Interest
         granted herein is, instead, a grant of an undivided two percent (2%)
         interest in the Properties (which the parties do not intend), then and
         only then such interest shall be deemed to be leased to HMC for the
         twenty (20) year term, at a lease royalty rate equivalent to one
         hundred percent (100%) of gross revenues attributable to the two
         percent (2%) interest, less an equivalent percentage of deductible
         costs as defined above, to be paid in the manner provided herein as and
         when due.

         Such lease would terminate on the twenty (20) year anniversary date
         hereof, subject only to accounting for. ores. previously severed, and
         title to HMC's interest in the Properties would be deemed to revest in
         HMC, or its successor in title to the Properties.

7.       This Grant shall continue to apply to any amendment, relocation or new
         location of the unpatented mining claims listed in Exhibit A (or, if
         the 1872 Mining Act be changed, to any new or successor interest as may
         be established or provided for under any successor law, including, but
         not limited to, a conversion or relocation of the unpatented claims)
         or, if applicable, after the grant of a mineral patent or patents. In
         the event that a successor interest is created, HMC agrees to evidence
         this grant in the form of a new writing applicable to the new or
         successor interest.

8.       Unless directed otherwise in writing by the Royalty Holders, HMC's
         payment obligations hereunder shall be deemed satisfied by making such
         payments as are required hereunder to the following account:

                  Account Number:                    1069518270
                  Bank Name:                         Bank One Boulder
                  Bank Wire Transfer Number:         ABA# 107000194

         and by providing the Royalty Holders with originals or copies of
         originals of the settlement documentation.

         for the interest being sold or disposed of and all other terms and
         conditions of the offer to include a description of any non-cash
         "consideration and its estimated cash value. If the parties disagree as
         to the cash value of any such non-cash consideration, the matter shall
         be resolved in accordance the Commercial Arbitration Rules of the
         American Arbitration Association in Denver, Colorado. For a period of
         thirty (30) days following receipt of such notice or the

<PAGE>

         determination by arbitration of the cash value of any non-cash
         consideration included in the notice, whichever is later, HMC shall
         have the first right and option to acquire the Net Smelter Return
         Royalty or the part thereof being sold or disposed of by the Royalty
         Holders upon the terms stated in the notice. The right and option of
         HWC to acquire the Net Smelter Return Royalty or interest therein being
         sold or disposed of by the Royalty Holders shall be exercised by
         written notice to the Royalty Holders within thirty (30) days from the
         effective-date of the original notice to HWC or from an arbitrator's
         decision on the cash value of any non-cash consideration included in
         the offer. If HWC exercises its option, closing of the acquisition
         shall take place within ten (10) days following the exercise of the
         option. The Royalty Holders shall execute an assignment of the Net
         Smelter Return Royalty or part thereof being sold or disposed of by the
         Royalty' Holders to HMC which shall contain a special warranty that the
         interest being assigned is free and clear of all liens, claims, clouds
         and encumbrances arising by, through or under the Royalty Holders. At
         Closing, HMC shall deliver to the Royalty Holders the cash
         consideration (including the estimated value of any non-cash
         consideration) for the interest being acquired by HMC by cashier's
         check or certified funds.

         If HMC fails to exercise its option as herein provided, the Royalty
         Holders may accept the bona fide offer extended to them or close the
         transaction they negotiated for the disposal of their Net Smelter
         Return Royalty or part thereof subject to being sold or disposed of;
         provided, however, that the Royalty Holders may not dispose of their
         interest for a consideration less favorable to them than the terms
         specified in the original notice given to HMC hereunder and provided,
         further, that if the Royalty Holders have not completed the sale of
         their interest, or the portion thereof set forth in the notice, within
         sixty (60) days following the expiration of the thirty (30) day period
         provided above, the provisions of this right of refusal shall again
         become effective.

10.      HMC shall have the right and option to elect to purchase the Royalty
         Interest from the Royalty Holders at any time during its term for the
         option Price of $1.5 million U.S. in cash ($1,500,000). Upon HMC's
         informing the Royalty Holders of its written election to purchase,
         there shall be created an agreement for the Royalty Holders to sell,
         and for HMC to purchase, the Royalty Interest.

         Closing shall be held at 1720 14th Street in Boulder, Colorado on the
         15th business day following the date of receipt of the written notice.
         The transfer shall be by Bargain and Sale Deed.

         The parties agree that the value of the Royalty Interest is highly
         speculative; Royalty Holders, for their part, agree that the grant of
         the Purchase Option is absolute, and that the Option may be" exercised
         at any time during its term, including the in event that minerals in
         commercial quantities are discovered on the Properties. For the
         purposes of clarity, the giving of notice of exercise of the Purchase
         option shall be the cutoff date for accounting for minerals upon which
         royalty may be due and owing as of the date of Closing, being all
         minerals which have been sold or shipped to the Purchaser as of that
         date.
