        Statements contained in the annual report that are not historical facts
are forward-looking statements as that term is defined in the Private Securities
Litigation Reform Act of 1995. Such forward-looking statements are subject to
risks and uncertainties, which could cause actual results to differ materially
from estimated results. Such risks and uncertainties are detailed in filings
with the Securities and Exchange Commission, including without limitation in
Item 1. "BUSINESS", Item 2. "PROPERTIES", and Item 7. "MANAGEMENT'S DISCUSSION
AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" below.

ITEM 1. BUSINESS

        AZCO Mining Inc. ("AZCO" or the "Company") is a U.S. mining company with
a general business strategy to acquire mineral properties. The Company plans to
supplement its core asset, a 30% interest in the Piedras Verdes project, through
the acquisition of other mining projects. The Company believes that numerous
opportunities exist to acquire such properties or companies, and that the
Company will be an effective competitor due to its strong cash position and
experienced management team. The Company plans to implement this strategy by
entering into joint ventures or corporate mergers, or by making property or
corporate acquisitions.

        Prior to the sale of the majority of its copper assets the Company was
dedicated to the development and production of low-cost copper utilizing solvent
extraction-electrowinning or the SX-EW process. AZCO's principal mineral
property was the Sanchez porphyry copper project ("Sanchez" or "Sanchez
Project") located about 10 miles northeast of the City of Safford in
southeastern Arizona, U.S.A. The Company also had interests in two other
porphyry copper properties, the Piedras Verdes and Suaqui Verde properties
located in Sonora State, Mexico.

        On July 27, 1995, the Board of Directors of AZCO (the "Board") signed
definitive agreements with Phelps Dodge Corporation ("Phelps Dodge" or "PDC") to
sell a substantial portion of the Company's assets. AZCO's shareholders approved
the sale of 100% of the Sanchez and 70% of the Piedras Verdes project for gross
consideration of $40 million.

        A predecessor of AZCO was incorporated on July 13, 1988 under the laws
of Colorado to acquire the mining rights to the Sanchez, as well as certain
other mineral properties. On August 27, 1991, the predecessor was merged into
AZCO, a newly incorporated Delaware corporation. In October 1991, AZCO acquired
all of the shares of Filton Enterprises Limited, a Gibraltar corporation
("Filton"), in return for the issuance of 3,650,000 common shares. At that time
Filton owned rights in two mining properties in Mexico, the Suaqui Verde project
in southeastern Sonora and the Piedras Verdes project in southern Sonora. Filton
was dissolved effective February 14, 1994 with its Mexican interests being
distributed to the Company.

        On July 31, 1992, AZCO merged with AZCO Mining Inc., a Wyoming
corporation ("AZCO (Wyoming)"), with AZCO being the survivor of the merger (the
"Merger"). At the time of the completion of the Merger AZCO (Wyoming) had
3,946,550 shares issued and outstanding and the Company had 12,633,822 common
shares issued and outstanding. One common share of the Company was issued in
exchange for each



                                        2
<PAGE>   3

share of AZCO (Wyoming) in connection with the Merger.  AZCO (Wyoming) was
formerly a British Columbia corporation which was incorporated under the laws of
the Province of British Columbia on August 20, 1981 under the name 241145 B.C.
Ltd.  241145 B.C. Ltd. changed its name to Canarex Resources Inc. on June 22,
1983, to International Baron Resources Ltd. on January 25, 1988 and finally to
AZCO Mining Inc. on February 20, 1992.  AZCO (Wyoming) was continued under the
laws of Wyoming effective May 13, 1992 prior to merging with AZCO.

SIGNIFICANT DEVELOPMENTS IN FISCAL 1998 AND SUBSEQUENT EVENTS

        On May 9, 1996 the Company signed an agreement with West Africa Gold &
Exploration Ltd., Eagle River International Limited ("Eagle") and Lion Mining
Finance Limited that provides for the establishment of a joint venture holding
company, Sanou Mining Corporation("Sanou"). Sanou is the sole beneficial owner
of a Malian subsidiary headquartered in Bamako and called Western African Gold
and Exploration Company S.A. ("Wag"), which has a 100% working interest in the
Medinandi and Dandoko concessions located in the Kenieba Gold Mining District of
western Mali. Eagle, the original principal concession owner through a Malian
subsidiary, has caused that subsidiary to convey the concessions to Wag.

        Effective August 9, 1996 Wag entered into a debenture agreement with
AZCO thereby acknowledging itself indebted to and promising to pay AZCO, in
consideration of financial advances and services then made, or thereafter made,
the aggregate principal sum of U.S.$4,000,000. All advances AZCO has made to
date under this agreement are also evidenced by promissory notes from Eagle.

        On September 3, 1997 AZCO served notice to Eagle stating that, due to
the fact that the work commitment for the license on the Mali project was
unacceptable, AZCO was declaring default of its May 9, 1996 agreement with the
same. In regard to the May 9, 1996 agreement among West African Gold &
Exploration Ltd., Eagle River International Limited, Lion Mining Finance Limited
and AZCO Mining Inc., AZCO gave notice of default to its joint-venture partners.
This dispute is still outstanding and the company is currently trying to resolve
it.

        Effective November 18, 1997, the Company and Lion Mining Corporation
Limited("Lion") entered into an agreement whereby Lion assigned to the Company
all of its interest in the Mali project and Lion agreed to grant the Company
first right on all mining opportunities which are brought to it for a minimum
three year period. For this consideration the Company indemnifies and holds
harmless Lion from all manner of action in connection with the Mali Project.

        On December 5, 1997, the Company announced that it had acquired the
option to explore, evaluate and purchase the Benitoite Gem Mine in San Benito
County, California. AZCO paid $20,000 for the option, and has until February 1,
1999 to evaluate the property. On or before this date the Company will have the
option to purchase the mine outright for $1.5 million, unencumbered by royalty.

        On March 4, 1998 Minera Phelps Dodge Mexico, S. de R.L. de C.V. informed
AZCO that it was dropping  its option with Cobre de Suaqui Verde, S.A. de C.V.
to explore the Suaqui Verde property.



                                        3
<PAGE>   4

        The Company announced on May 20, 1998, that it had signed a letter of
agreement with Chivor Emerald Corporation whereby, subject to satisfactory due
diligence, AZCO would acquire all of Chivor's emerald mining interests in
Colombia. On July 23, 1998, the Company announced that, after careful
consideration of the Colombian emerald project presented by Chivor Emerald
Corporation, it was determined that the project was not appropriate for the
Company's development plans and correspondingly, the Company determined not to
proceed.

        On June 18, 1998, The Company entered into an agreement with Minera
Cortez Resources Ltd. (Cortez) whereby the Company was granted a right of first
refusal for a period of five years to acquire all or any of the property
interest that Cortez desires to either joint venture, option, or dispose of. In
consideration, the Company has subscribed for 200,000 common shares of Cortez at
Cdn. $.025 per share. The Company was also granted a right of first refusal for
the same period to provide up to 100% of any private or public equity or debt
financing that Cortez proposes to obtain, on similar terms as any third party is
willing to provide.

        On July 21, 1998, the Company entered into an option agreement with
Cortez whereby the Company was granted an option to earn up to 70% interest in
the La Adelita property in Sonora, Mexico under the following terms:

i.      by subscribing to 100,000 common shares of Cortez at Cdn. $0.25 per
        share

ii.     by making option payments and paying finder's fees on behalf of Cortez
        totalling $165,000 over the next five years

iii.    by incurring exploration expenditures on the property totalling $500,000
        over the next three years.

        On May 22, 1998, the Company entered into an agreement to purchase a
$1,500,000 convertible debenture of Oro Argentina Limited (OAL) for the purpose
of financing the first phase of the Chiqua White Bentonite Project and the
option payments of OAL. OAL has an option to acquire a 50% interest in the
Bentonite Project in San Juan, Argentina pursuant to an agreement dated February
2, 1998 between OAL and Pierre Martre. The debenture bears interest at 12% per
annum and is due on September 1, 2000. During the term of the debenture, the
Company has the option to convert the unpaid balance of the principal and
interest into common units of OAL at $0.50 per unit, where each unit consists of
one common share and one warrant, and each warrant entitles the Company to
purchase an additional common share at $0.60 per share for a period of two years
after conversion. the debenture is secured by a first floating and fixed charge
on the assets of OAL.

        As at June 30, 1998, $100,000 has been drawn against the debenture by
OAL.

        The Company was also granted a two-year option to purchase all of the
shares of OAL, subject to OAL shareholders' approval. Pursuant to the terms o
the agreement, if the financing of the second phase of the project is not in
place after 18 months from the issue of the debenture, the Company can extend
the option for an additional year. The exercise of the option will be paid with
common shares of the Company at a ratio of one common share for two shares of



                                        4
<PAGE>   5

OAL. The shares of the Company issued for the currently issued and outstanding
10,136,935 shares of OAL and any other shares issued pursuant to the purchase
option will be placed into a pool for a period of two years, 25% of which will
be release immediately, 25% one year thereafter, and the remaining 50% two years
thereafter.

        The Company has also advanced $24,371 to OAL for option payments and
other expenses related to the Bentonite Project. The loan bears interest at 12%
per annum and is due on March 9,1999. In the event that the loan and accrued
interest are not repaid by the due date, they are automatically converted into
Class S shares of OAL at $0.50 per share as full repayment of the loan. The loan
has been recorded on the Company's balance sheet in prepaid and other at June
30, 1998.

        On April 6, 1998, the Company entered into an agreement with Lines
Overseas Management Ltd. (Lines), subject to regulatory approval. Under the
terms of the Mali agreement, Lines had originally advanced $500,000 and 125,000
shares of the Company owned by it to Eagle River for payments to Guefest and
other parties. The Company has agreed to issue 375,000 of its shares to Lines in
consideration for assigning and quitclaiming to the Company all advances and any
other benefit or claim of Lines related to the Mali agreement.

REPURCHASE PROGRAM

        On August 6, 1998, the Company approved the repurchase of up to
1,284,024 shares of its issued and outstanding shares of its issued and
outstanding common Stock on the American Stock Exchange commencing August 13,
1998 and continuing up until August 13, 1999. The maximum authorized repurchase
price is $1.50 per common share. Through September 25, 1998 the Company has
repurchased 254,676 shares for $162,543 under the plan. The Company's Board of
Directors authorized the share repurchase program because it believes that the
current price levels for the Company's stock do not reflect the value of the
Company's assets and growth prospects.

EXPLORATION AND DEVELOPMENT

     During fiscal 1998 the Company received no material revenues other than
interest income, as the Company has no mineral properties in production.

        Exploration expenses of $1,101,188 were incurred as the Company funded
its 30% share of the Piedras Verdes project. The Company has fulfilled its
$3,000,000 commitment, through pre feasibility, under the Cobre del Mayo
shareholders' agreement.

        Exploration expense in Indonesia totaled $70,172 during fiscal 1998 in
addition $370,505 of refundable deposits held by the Indonesian Ministry of
Mines were written-off. These deposits were written off because of the
uncertainty of their recoverability due to the current economic conditions in
Indonesia.

        During fiscal 1998 AZCO incurred $783,672 of exploration expense on the
Mali project. The Company is currently in negotiations with potential
joint-venture partners and anticipates entering into an agreement soon.



                                        5
<PAGE>   6

        The Company incurred exploration expense of $973,830 for its gemstone
initiative. Expenses of $396,178 and $577,651 were accumulated on the Chivor
Emerald and California Benitoite projects, respectively.

EMPLOYEES

     As of August 15, 1998, there were 9 full-time employees of AZCO. None of
these employees are represented by a labor union contract or a collective
bargaining agreement.

LAWS AND REGULATIONS

        AZCO's interests in its projects will be subject to various laws and
regulations concerning development, production, taxes, labor standards,
environmental protection, mine safety and other matters. In addition, new laws
or regulations governing operations and activities could have a material adverse
impact on AZCO.

FOREIGN COUNTRIES AND REGULATORY REQUIREMENTS

        AZCO has mineral interests located in Mexico, Indonesia and Mali.
Mineral exploration, development and mining activities on its interests may be
effected in varying degrees by political stability, and the policies of other
nations in respect of these countries. Any changes in regulations or shifts in
political conditions are beyond the control of the Company and may adversely
affect its business. Operations may be affected in varying degrees by government
regulations, including those with respect to export controls, expropriation of
property, employment, land use, water use, environmental legislation and mine
safety. Operations may be also affected in varying degrees by political and
economic instability, economic or other sanctions imposed by other nations,
terrorism, military repression, crime, extreme fluctuations in currency exchange
rates and high inflation.

SEASONABILITY

        It is not anticipated that AZCO's Mexican interests in the state of
Sonora will be of a seasonable nature. The Company is aware of the fact that
circumstances in other parts of the world, such as Mali and Indonesia, do make
exploration, mining and mineral processing a seasonal endeavor.

COMPETITIVE CONDITIONS

        Many companies are engaged in the exploration and development of mineral
properties. Since many of these companies have substantially greater technical
and financial resources than the Company, the Company may be at a disadvantage
with respect to some of its competitors.

        The marketing of minerals is affected by numerous factors, many of which
are beyond the control of the Company. Such factors include the price of the
mineral in the marketplace, imports of minerals from other nations, the
availability of adequate refining and processing facilities, the price of fuel,
electricity, labor, supplies and reagents and the market price of competitive
minerals. In addition, sale prices for many commodities are determined by world



                                        6
<PAGE>   7

market forces or are subject to rapid and significant fluctuations that may not
necessarily be related to supply or demand or competitive conditions that in the
past have affected such prices.

ENVIRONMENTAL

        In connection with its future mining and processing operations, the
Company will be required to comply with various federal, state and local laws
and regulations pertaining to the discharge of materials into the environment.
The Company will also be required to maintain various permits and licenses
necessary for its operations from appropriate regulatory agencies. Apart from
capital expenditures associated with the construction and maintenance of
facilities required for usual mining and processing activities, the Company does
not anticipate that compliance with environmental laws will have a material
adverse effect upon the capital expenditures, earnings and competitive position
of the Company for the remainder of the current fiscal year, the next fiscal
year or in subsequent periods deemed material by the Company. AZCO is not
currently subject to any material proceedings arising under environmental laws
and regulations.

        In light of the nature of its business the Company could face
significant exposure from potential claims involving environmental matters.
These matters could involve alleged soil, air and water contamination, and
personal injuries or property damage allegedly caused by toxic materials handled
or used by the Company in connection with its mining activities. The Company's
policy is to accrue environmental and cleanup costs when it is probable that a
liability has been incurred and the amount of such liability is determinable.
However, future environment-related expenditures cannot be reasonably quantified
in many circumstances due to the speculative nature of remediation and cleanup
costs, estimates and methods, the imprecise and conflicting data regarding the
characteristics of various types of materials and waste, the unknown number of
other potentially responsible parties involved, the extent to which such costs
may be recoverable from insurance and changing environmental laws and
interpretations. As a result the Company believes its future environment-related
expenditures potentially could become material at some point, but the amount of
such expenditures are uncertain at this time.


ITEM 2. PROPERTIES


PIEDRAS VERDES PROJECT

        The Piedras Verdes property is leased by Cobre del Mayo, S.A. de
C.V.("Cobra del Mayo"), a Mexican corporation that is owned 30% by AZCO and 70%
by Minera Phelps Dodge Mexico S. de R.L. de C.V.("MPDM"), a subsidiary of Phelps
Dodge. The property consists of approximately 640 hectares and is located in
southern Sonora State, Mexico.

        Prior to the sale of a 70% interest in Cobre del Mayo to MPDM, 242
reverse circulation holes totalling 26,815 meters had been drilled. Since the
sale of the 70% interest in Cobre del Mayo to MPDM 217 holes totaling 47,869
meters have been cored. In addition, the geologic mapping has been expanded,
metallurgical testing has advanced and a geological and ore deposit model has
been prepared.



                                        7
<PAGE>   8

A pre-feasibility report has been prepared but, due to depressed copper prices,
the project is currently on hold.

        The Company estimates that the Piedras Verdes property contains a 316
million ton deposit grading .037% copper or 2.34 billion pounds of contained
copper(at a .02% cut-off).


SUAQUI VERDE PROJECT

        The Suaqui Verde copper property is leased by Cobre de Suaqui Verde,
S.A. de C.V., a Mexican corporation that is owned 99.97% by AZCO. The project is
located in southeastern Sonora State, Mexico, near the town of Suaqui Grande,
which is about 350 km south of the U.S.- Mexico border and 160 km southeast of
Hermosillo (population 600,000), the state capital.

        On June 20, 1996, Cobre de Suaqui Verde, S.A. de C.V. entered into an
agreement (the "Agreement") with MPDM for the exploration of its Suaqui Verde
property.

        Effective March 4, 1998, MPDM terminated the Agreement with AZCO and
Cobre De Suaqui Verde, S.A. de C.V. It is the intent of AZCO to analyze the
results of the recent work on the Suaqui Verde project and make a decision as to
its continued involvement with the project.


MALI GOLD CONCESSIONS

        On May 9, 1996 the Company signed an agreement with West Africa Gold &
Exploration Ltd., Eagle and Lion that provides for the establishment of a joint
venture holding company, Sanou. Sanou is the sole beneficial owner of a Malian
subsidiary headquartered in Bamako and called Wag, which has a 100% working
interest in the Medinandi and Dandoko concessions located in the Kenieba Gold
Mining District of western Mali. Eagle, the original principal concession owner
through a Malian subsidiary, has caused that subsidiary to convey the
concessions to Wag.

        Effective August 9, 1996 Wag entered into a debenture agreement with
AZCO thereby acknowledging itself indebted to and promising to pay AZCO, in
consideration of financial advances and services then made, or thereafter made,
the aggregate principal sum of U.S.$4,000,000. All advances AZCO has made to
date under this agreement are also evidenced by promissory notes from Eagle.

        On September 3, 1997 AZCO served notice to Eagle stating that, due to
the fact that the work commitment for the license on the Mali project was
unacceptable, AZCO was declaring default of its May 9, 1996 agreement with the
same. In regard to the May 9, 1996 agreement among West African Gold &
Exploration Ltd., Eagle River International Limited, Lion Mining Finance Limited
and AZCO Mining Inc., AZCO gave notice of default to its joint-venture partners.
This dispute is still outstanding and the company is currently trying to resolve
it.
        Effective November 18, 1997, the Company and Lion Mining Corporation
Limited("Lion") entered into an agreement whereby Lion assigned to the Company



                                        8
<PAGE>   9

all of its interest in the Mali project and Lion agreed to grant the Company
first right on all mining opportunities which are brought to it for a minimum
three year period. For this consideration the Company indemnifies and holds
harmless Lion from all manner of action in connection with the Mali Project.

        On December 18, 1997, Western African Gold and Exploration Company - SA
was granted a renewable exploration agreement on the holdings of the Mali
project. The new agreement runs through December 1998 and has a $3,360,000 work
commitment assigned to it which has been fulfilled to date. The Company is
currently in negotiations with potential joint venture partners on the Mali
project and plans to submit a proposed exploration program and application for
renewal of the exploration concession with the Ministry of Mines in Mali.


PONGKOR PROPERTIES

        The South and West Pongkor properties adjoin the claim block containing
the 3 million ounce Pongkor Gold Mine in the Bayah Dome area of Western Java in
Indonesia. AZCO does not own any interest in the Pongkor Gold Mine.
Mineralization is known on both claim blocks, neither of which has been explored
by modern methods. In recent years accessibility has been greatly improved with
road access running to the heart of each property. Both properties are highly
prospective for low sulphidation epithermal mineralization, containing
opportunities not only for small tonnage, high-grade mineralization but also for
bulk-tonnage, open pit targets. There are no proven or probable reserves at the
Pongkor properties at this time.

        AZCO has completed a geologic evaluation of the Pongkor properties and
has compiled an extensive report which is currently being disseminated to a
number of companies, which have expressed an interest in joint-venturing the
properties.


ITEM 3. LEGAL PROCEEDINGS

        On November 24, 1997 a Deed of Release and Compromise was entered into
by AZCO, Sanchez and AIOC Corporation("AIOC") settling all outstanding
differences between the parties including, without limitation, certain matters
being arbitrated under the rules of the London Metal Exchange. The Company
received the $4,000,000 held in escrow to satisfy any award in the AIOC
arbitration and remitted a payment of $400,000 to AIOC in full and final
settlement of all matters and claims as between the parties.

ITEM 7. MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
        OPERATIONS


GENERAL

        All material revenues received during fiscal 1998 and 1997 were a result
of interest earned on the proceeds of the sale of assets to Phelps Dodge. All
funds raised prior to fiscal 1996 were used in the exploration and development
of the Company's properties.

RESULTS OF OPERATIONS

TWELVE MONTHS ENDED JUNE 30, 1998 COMPARED TO TWELVE MONTHS ENDED JUNE 30, 1997.

        AZCO had a net loss of $3,044,112 for fiscal 1998 compared to net loss
of $8,155,700 in 1997. The reduction in net loss for the year ended June 30,
1998 is the result of a decrease in exploration expenditures of $4,313,601.

        Exploration expense in 1998 was $3,261,405 as compared to $7,575,006 in
1997. The Company, in fiscal 1998, funded $1,101,188 for its 30% share of the
costs related to the Piedras Verdes project compared to $1,846,330 in fiscal



                                       11
<PAGE>   12

1997. During the fiscal year ended June 30, 1998 AZCO expended $783,672 on the
Mali project as compared to $4,052,316 in the previous fiscal year. In fiscal
1998 a total of $290,678 was expensed against the Indonesian properties in
contrast to $1,211,549 during fiscal 1997. In addition, the Company incurred
expenses of $973,830 relating to its gemstone initiative in fiscal 1998.

        Accounting and legal expenses increased from $254,288 in 1997 to
$386,870 in 1998. Increased legal expense in 1998 is the result of the AIOC
settlement.

        Miscellaneous expense in fiscal 1998 resulted from the $400,000 payment
to AIOC as full and final payment of all matters and claims between AIOC, AZCO
and Sanchez Mining Inc.


TWELVE MONTHS ENDED JUNE 30, 1997 COMPARED TO TWELVE MONTHS ENDED JUNE 30, 1996.

        AZCO had a net loss of $8,155,700 for fiscal 1997 compared to net income
of $17,127,455 in 1996. This was the result of the gain on the sale of assets to
Phelps Dodge of $26,076,026 recognized in the year ended June 30, 1996.

        Salaries expense was $1,107,910 during 1997 compared to $774,461 in
1996. The increase was due primarily to a severance payment of $193,846 and
$149,996 of compensation expense to account for the fair value of stock options
granted to non-employees during the year ended June 30, 1997.

        General and administrative expense was $1,037,253 during 1997 compared
to $772,997 during 1996. This increase in 1997 was due to increases in general
office and investor relations expenditures of $127,963 and $104,713,
respectively.

        Exploration expense in 1997 was $7,575,006 as compared to $738,597 in
1996. The Company funded $1,846,330 for its 30% share of the costs related to
the Piedras Verdes project. In addition, expenditures of $14,344 were incurred
to sustain the Suaqui Verde project. AZCO expended $4,052,316 on the Mali
project and an additional $352,659 on other various African projects in
connection with its then strategic alliance with Eagle. A total of $1,211,549
was expended on the four Indonesian properties AZCO was involved with in 1997.
In addition, the Company had general exploration expense of $97,807 in 1997. The
large increase in exploration activity in 1997 represents the Company's change
in direction from a development stage mining company with the Sanchez project in
1996 to a pure exploration company in 1997.

        Accounting and legal expenses decreased from $578,928 in 1996 to
$254,288 in 1997. The decrease in legal expense in 1997 is the result of the
consent solicitation initiated by Muzinich & Co. in fiscal 1996.

        The Company did not incur interest expense in 1997 as all debt was
retired with the proceeds of the Phelps Dodge sale in 1996.

LIQUIDITY AND CAPITAL RESOURCES

        For the fiscal year ended June 30, 1998, the Company met its capital
requirements through the proceeds of the sale of assets to Phelps Dodge in 1996.

        At June 30, 1998 and June 30, 1997 the Company had cash and cash
equivalents of $18,320,882 and $17,080,260, respectively, and working capital of
$19,021,047 and $17,337,937, respectively. Total liabilities as of June 30, 1997
were $337,050 as compared to $299,061 on June 30, 1998.

        The Company feels that its current cash position is strong enough to
fund all capital requirements in fiscal 1999. In the event that a production
decision is made in regards to the Piedras Verdes project it is the Company's
intention to raise additional capital to fund its share of the construction
costs. Funding of the ongoing exploration projects in California, Mali,
Indonesia and Mexico (including approximately $4.1 million in potential
pre-production royalties on the Piedras Verdes project over the next 10 years)
is expected to come from either the Company's treasury or from potential joint
venture partners. In the event that is not possible additional funding will be
sought to fund the advance royalties on the Piedras Verdes project if the
Company chooses to retain its interest in the project.

ADDRESSING THE YEAR 2000

        The Year 2000 issue arises because many computerized systems use two
digits rather than four to identify a year. Date-sensitive systems may recognize
the year 2000 as 1900 or some other date, resulting in errors when information
using year 2000 dates is processed. In addition, similar problems may arise in
some systems which use certain dates in 1999 to represent something other than a
date. The effects of the Year 2000 Issue may be experienced before, on or after
January 1, 2000, and, if not addressed, the impact on operations and financial
reporting may range from minor errors to significant systems failure which could
affect an entity's ability to conduct normal business operations. However, the
Company has installed updated accounting software which addresses the potential
year 2000 problem. It is anticipated that there will be no material impact on
the Company. It is not possible to be certain that all aspects of the Year 2000
Issue affecting the Company including those related to the efforts of customers,
suppliers, or other third parties, will be fully resolved.

COMPLIANCE WITH SECTION 16(a)BENEFICIAL OWNERSHIP REPORTING COMPLIANCE, OF THE
EXCHANGE ACT OF 1934

        Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's officers and directors, and persons who own more than ten percent of a
registered class of the Company's equity securities, to file reports of
ownership and changes in ownership with the Securities and Exchange Commission
(the "SEC"). Officers, directors and greater than ten percent shareholders are

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Azco Mining Inc. (Delaware)


We have audited the consolidated financial statements and the financial
statement schedule of Azco Mining Inc. (Delaware) and its subsidiaries listed in
the index on page F-1 of this Form 10-K. These financial statements and the
financial statement schedule are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements and
the financial statement schedule based on our audits.

We conducted our audits in accordance with United States generally accepted
auditing standards. Those standards require that we plan and perform an audit to
obtain reasonable assurance whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of Azco Mining Inc. (Delaware) and its
subsidiaries as at June 30, 1998 and 1997, and the consolidated results of their
operations and their cash flows for each of the three years in the period ended
June 30, 1998 in conformity with United States generally accepted accounting
principles. In addition, in our opinion, the financial statement schedule
referred to above, when considered in relation to the basic consolidated
financial statement taken as a whole, presents fairly, in all material respects,
the information required to be included therein.



PricewaterhouseCoopers is a Canadian member firm of PricewaterhouseCoopers
International Limited, an English company limited by guarantee.

AZCO MINING INC. (DELAWARE)
Notes to Consolidated Financial Statements
For the years ended June 30, 1998, 1997 and 1996

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



1.   NATURE OF OPERATIONS

     Azco Mining Inc. (Delaware) (the Company) is a U.S. mining company with a
     general business strategy to acquire mineral properties. The Company plans
     to supplement its core asset, a 30% interest in the Piedras Verdes Project,
     through its acquisition of other mineral properties. As at June 30, 1998,
     none of the properties had proven reserves of commercial ore.

     Although the Company has taken steps to verify title to mineral properties
     in which it has an interest, according to the usual industry standards for
     the stage of exploration of such properties, these procedures do not
     guarantee the Company's title. Such properties may be subject to prior
     agreements or transfers and title may be affected by undetected defects.


2.   SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF CONSOLIDATION

     These consolidated financial statements include the accounts of the Company
     and its majority-owned subsidiaries.

     CASH AND CASH EQUIVALENTS

     The Company considers all liquid investments purchased with a maturity of
     three months or less to be cash equivalents. Cash and cash equivalents are
     stated at cost which approximates market value.

     MINERAL PROPERTIES

     The Company expenses prospecting and exploration costs and capitalizes
     costs directly attributable to the acquisition of mining properties,
     pending determination as to their commercial feasibility (to contain a
     viable mineral deposit). Development costs are capitalized and, upon
     commencement of production, will be amortized using the units-of-production
     method. Gains or losses resulting from the sale or abandonment of mineral
     properties are included in operations. Proceeds from sales of properties in
     which the Company has retained an economic interest are credited against
     property costs, and no gain is recognized until all costs have been fully
     recovered.

     PROPERTY EVALUATION

     Recoverability of investments in non-operating properties is evaluated
     periodically. Estimated future net cash flows from each property are
     calculated using estimates of proven and probable ore reserves, estimated
     future prices (considering historical and current prices, price trends, and
     related factors), operating capital, and reclamation costs on an
     undiscounted basis. Reductions in the carrying value of each property are
     recorded to the extent the remaining investment exceeds the estimate of
     future net cash flows.

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

2.   SIGNIFICANT ACCOUNTING POLICIES (cont'd)

     PROPERTY EVALUATION (cont'd)

     Where properties are held for sale, recoverability is assessed based on
     management's estimate of fair value. Reductions in the carrying value of
     each property are recorded to the extent the remaining investment exceeds
     fair value, less costs of disposal.

     FURNITURE AND EQUIPMENT

     Furniture and equipment are carried at cost. Replacements, maintenance and
     repairs that do not improve or extend the life of the respective assets are
     expensed. Major renewals and improvements are capitalized. Upon retirement,
     sale or other disposition of furniture and equipment, the cost and
     accumulated depreciation are eliminated from the accounts and the gain or
     loss is included in operations.

     The Company depreciates these assets over their estimated useful lives (3 -
     5 years) using the straight-line method.

     INCOME TAXES

     The Company accounts for income taxes under Statement of Financial
     Accounting Standards No. 109, "Accounting for Income Taxes." Income taxes
     and liabilities are recognized for the expected future tax consequences of
     events that have been included in the financial statements or income tax
     returns. Deferred tax assets and liabilities are determined based on the
     difference between the financial statements and tax bases of assets and
     liabilities using enacted tax rates in effect for the year in which the
     differences are expected to reverse.

     ESTIMATES

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

2.   SIGNIFICANT ACCOUNTING POLICIES (cont'd)

     STOCK-BASED COMPENSATION

     In October 1995, the Financial Accounting Standards Board issued Statement
     of Financial Accounting Standards No. 123, "Accounting for Stock-Based
     Compensation," (SFAS No. 123), which defines a fair value based method of
     accounting for employee (including directors) stock options for similar
     equity instruments. However, it also allows an entity to continue to
     account for these plans according to Accounting Principles Board Opinion
     No. 25, "Accounting for Stock Issued to Employees," (APB No. 25), provided
     pro forma disclosures of net income and earnings per share are made as if
     the fair value based method of accounting defined by SFAS No. 123 has been
     applied. The Company has elected to continue to measure compensation
     expense related to employee stock purchase options using APB No. 25. The
     fair value of options granted to non-employees and directors is expensed as
     compensation when options are granted, and the corresponding amount is
     credited to stockholders' equity.


3.   CONCENTRATIONS OF CREDIT RISK

     Financial instruments that potentially subject the Company to significant
     concentrations of credit risk consist principally of cash and cash
     equivalents. The Company invests its cash and cash equivalents in high
     quality issuers with credit quality at the time of purchase of at least
     A1/P1 or A. The Company, in the normal course of business, maintains cash
     balances in excess of the Federal Deposit Insurance Corporation's insurance
     limit. At June 30, 1998 and 1997, cash equivalents of $18,300,000 and
     $16,800,000, respectively, were invested by one bank's trust and
     institutional portfolio department.


4.   INVESTMENT AND ADVANCES

  (a)  INVESTMENT

     On June 18, 1998, the Company entered into an agreement with Minera Cortez
     Resources Ltd. (Cortez), a private company, whereby the Company was granted
     a right of first refusal for a period of five years to acquire all or any
     of the property interest that Cortez decides to either joint venture,
     option, or dispose of. In consideration, the Company has subscribed for
     200,000 common shares of Cortez at Cdn. $0.25 per share. The Company was
     also granted a right of first refusal for the same period to provide up to
     100% of any private or public equity or debt financing that Cortez proposes
     to obtain, on similar terms as any third party is willing to provide.

4.   INVESTMENTS AND ADVANCES (cont'd)

  (b)  ADVANCES

     On May 22, 1998, the Company entered into an agreement to purchase a
     $1,500,000 convertible debenture of Oro Argentina Limited (OAL) for the
     purpose of financing the first phase of the Chiqua White Bentonite Project
     and the option payments of OAL. OAL has an option to acquire a 50% interest
     in the Bentonite Project in San Juan, Argentina pursuant to an agreement
     dated February 2, 1998 between OAL and Pierre Martre. The debenture bears
     interest at 12% per annum and is due on September 1, 2000. During the term
     of the debenture, the Company has the option to convert the unpaid balance
     of the principal and interest into common units of OAL at $0.50 per unit,
     where each unit consists of one common share and one warrant, and each
     warrant entitles the Company to purchase an additional common share at
     $0.60 per share for a period of two years after conversion. The debenture
     is collateralized by a first floating and fixed charge on the assets of
     OAL.

     As at June 30, 1998, $100,000 has been drawn against the debenture by OAL.

     The Company was also granted a two-year option to purchase all of the
     shares of OAL, subject to OAL shareholders' approval. Pursuant to the terms
     of the agreement, if the financing of the second phase of the project is
     not in place after 18 months from the date of issue of the debenture, the
     Company can extend the option for an additional year. The exercise of the
     option will be paid with common shares of the Company at a ratio of one
     common share for two shares of OAL. The shares of the Company issued for
     10,136,935 issued and outstanding shares of OAL and any other shares issued
     pursuant to the purchase option will be placed into a pool for a period of
     two years, 25% of which will be released immediately, 25% one year
     thereafter, and the remaining 50% two years thereafter.

     The Company has also advanced $24,371 to OAL for option payments and other
     expenses related to the Bentonite Project. The loan bears interest at 12%
     per annum and is due on March 9, 1999. In the event that the loan and
     accrued interest are not repaid by the due date, they are automatically
     converted into Class S shares of OAL at $0.50 per share as full repayment
     of the loan. The loan has been recorded in prepaids and other at June 30,
     1998.


5.   MINERAL PROPERTIES

  (a)  SANCHEZ PROJECT

     During the year ended June 30, 1996, the Company sold 100% of its
     investment in the Sanchez property located in Graham County, Arizona.
     Proceeds of $37,000,000 from the sale were received and a gain of
     $26,076,026 was recorded.

5.   MINERAL PROPERTIES (cont'd)

   (b)  PIEDRAS VERDES PROJECT

     The Piedras Verdes Project is located in southern Sonora, Mexico. During
     the year ended June 30, 1996, the Company sold 70% of its interest in the
     Piedras Verdes Project to Phelps Dodge Corporation (Phelps Dodge). In
     accordance with the Company's policy regarding sales of mineral properties,
     proceeds of $3,000,000 from the sale were credited against the remaining
     development costs and no gain was recognized.

     Under the terms of the sales agreement with Phelps Dodge, all assets and
     commitments related to this project were transferred to a separate company
     incorporated as Cobre del Mayo, S.A. de C.V. (Cobre). The Company maintains
     a 30% interest and Phelps Dodge a 70% interest in Cobre. Under the terms of
     the Shareholders' and Operator's Agreement among Phelps Dodge, Cobre del
     Mayo, Inc., the Company, and Cobre, the Company committed to provide up to
     $3,000,000 for costs required to bring the Piedras Verdes Project to the
     feasibility stage. As at June 30, 1998, the Company has advanced $3,669,761
     towards the project. The Company also committed to funding its 30% of
     expenditures incurred in the feasibility stage. The Company is expensing
     all costs related to the project.

     On March 4, 1997, Cobre entered into a mining exploration and exploitation
     agreement with Compania Minera Serrana, S.A. de C.V. This agreement
     superseded the pre-existing lease. Under the terms of this agreement, Cobre
     has the following commitments to be funded 70% by Phelps Dodge and 30% by
     the Company:

     -    $10,000 per month from the execution of the agreement until production
          begins

     -    three payments of $299,035 due on the date of execution and on the
          first and second anniversaries of the date of execution

     -    royalties equal to three percent of the net value of mineral
          production

     -    advance royalties of $1,000,000 on the third through fifth
          anniversaries of the date of execution, and $1,500,000 on the sixth
          through eleventh anniversaries if commercial production is not met by
          those anniversary dates.

   (c)  SUAQUI VERDE PROJECT

     On June 20, 1996, the Company entered into a Mineral Exploration and Option
     to Form Company Agreement with Minera Phelps Dodge Mexico (MPDM) for the
     mineral exploration and evaluation of the Suaqui Verde mineral concessions
     in Sonora, Mexico. Under the terms of the agreement, MPDM could earn a 70%
     interest in the concessions by incurring exploration expenditures of
     $2,000,000 on the project over three years, funding the completion of a
     comprehensive feasibility study, and paying the Company $25,000 annually.

   (c)  SUAQUI VERDE PROJECT (cont'd)

     During the year ended June 30, 1998, the option agreement was terminated.

     The Company is committed to pay $24,000 annually to the property owners.

   (d)  MALI PROJECT

     On May 9, 1996, the Company entered into a Memorandum of Agreement with
     West African Gold and Exploration, Ltd. (WAG), a British Virgin Islands
     company, Eagle River International Limited (Eagle River), a Vanuatu
     corporation, and Lion Mining Finance Limited (Lion Mining), a United
     Kingdom corporation. Eagle River has purchased properties in Mali, Africa
     from Guefest, a Russian mining consortium. Under the terms of this
     agreement, the properties were transferred to West African Gold (Mali) Inc.
     (WAG (Mali)) on July 7, 1997. Shares in this corporation have been
     transferred to Chaplin Holding Ltd., a Bahamian company, which has changed
     its name to Sanou Mining Corporation (Sanou). The Company currently holds a
     100% interest in Sanou.

     On May 17, 1996, under the terms of the above agreement, the Company issued
     an irrevocable standby letter of credit in the amount of $1,000,000 to
     guarantee the development of certain mineral concessions in Mali. The
     Company, on behalf of Eagle River, Lion Mining, and WAG, had guaranteed
     $1,000,000 of development by May 15, 1997 to keep the properties in good
     standing. During the year ended June 30, 1997, the Company funded
     $4,052,316 for operating costs on the Mali Project, which exceeds the
     required expenditures. The operating costs are included in exploration
     costs in the accompanying statement of operations.

     On September 3, 1997, the Company served notice to Eagle River that it was
     declaring default of the Mali agreement as the work commitment for the
     licence on the Mali Project was unacceptable. Under the terms of the
     agreement, Eagle River and Lion Mining have to repay all advances made by
     the Company towards the Mali Project. These advances were secured by
     promissory notes from Eagle River and debentures from Societe Olifer de
     Falome (SOF) and WAG Mali in the amount of $4,000,000. The Company is in
     the process of foreclosure on these securities and, as a consequence, takes
     the position that it is the 100% owner of the mining concessions through
     its subsidiaries WAG and Sanou and will pursue Eagle River and SOF for any
     value shortfall.

   (d)  MALI PROJECT (cont'd)

     On November 18, 1997, the Company entered into an agreement with Lion
     Mining forming a joint venture called the Kingfisher Venture created to
     pursue profitable exploitation of mineral opportunities located by Lion
     Mining. Pursuant to the terms of the agreement, Lion Mining will seek and
     make available to the venture mineral opportunities coming to them in which
     they are capable of participating, and the Company has the right of first
     refusal on these opportunities. The term of the venture is the longer of
     three years or the payout of the Negative Balance plus six months, expiring
     on December 31, 2010. The Negative Balance is equal to the total
     expenditures related to the Mali agreement less all recoveries. Lion Mining
     has also assigned to the Company all its rights and interests in the Mali
     agreement and has agreed to cooperate fully with the Company in pursuit of
     any remedies against Eagle River. The Company has released and discharged
     Lion Mining of all suits, debts, and claims related to the Mali agreement.
     The Company plans to foreclose on the promissory notes of Eagle River.

     On December 18, 1997, WAG (Mali) was granted a renewable exploration
     agreement on the Mali Project by the Mali Ministry of Mines and Energy. The
     agreement runs through December 1998 and has a work commitment of
     $3,360,000 assigned to it. As of June 30, 1998, this work commitment has
     been fulfilled.

     On April 6, 1998, the Company entered into an agreement with Lines Overseas
     Management Ltd. (Lines), subject to regulatory approval. Under the terms of
     the Mali agreement, Lines had originally advanced $500,000 and 125,000
     shares of the Company owned by it to Eagle River for payments to Guefest
     and other parties. The Company has agreed to issue 375,000 of its shares to
     Lines in consideration for assigning and quitclaiming to the Company all
     advances and shares and any other benefit or claim of Lines related to the
     Mali agreement. These shares were issued on September 17, 1998.

   (e)  INDONESIA PROJECTS

     During the year ended June 30, 1997, the Company entered into certain
     agreements to obtain the rights to explore properties in Indonesia. As a
     part of the agreements, the Company was obligated to pay all costs required
     under Indonesian law. These costs include funds required to be put on
     deposit with the Indonesian Ministry of Mines to obtain Contracts of Work
     (CoWs).

     On December 1, 1997, the Company entered into an agreement whereby it was
     granted an option to purchase the Benitoite mineral property in San Benito
     County, California for a purchase price of $1,500,000. The Company can
     exercise the option on or before February 1, 1999. Pursuant to the terms of
     the agreement, the Company has made a non-refundable payment of $20,000 to
     the property owners.


6.   NOTES PAYABLE

     On May 12, 1995, the Company issued $2,000,000, 14% convertible debentures.
     Interest at 14% per annum was payable semi-annually from the issue date.
     The convertible debentures could have been converted to common stock at the
     option of the investor at any time during the two-year term of the
     convertible debentures for $2.00 per share. The convertible debentures were
     subordinated to any and all security or obligations that may have been
     issued or incurred by the Company in connection with the Company's debt
     financing requirement for its mineral properties. The convertible
     debentures were paid in full on December 19, 1995. No penalty was assessed
     for early extinguishment of the debt.

     STOCK OPTIONS

     The Company has elected to follow APB No. 25 and related interpretations in
     accounting for its stock-based employee compensation arrangements. Under
     APB No. 25, as the exercise price of the Company's stock options equals the
     market price of the underlying stock on the date of grant, no compensation
     expense is recognized.

     The Company has a Stock Option Plan (the Plan) dated July 24, 1989, as
     amended, for the granting of options to purchase common stock. The board of
     directors may grant options to key personnel and others as it deems
     appropriate. There are no vesting requirements under the Plan. The options
     are exercisable over a maximum term of five years.

     Pro forma information regarding net income and earnings per share is
     required by SFAS No. 123, and has been determined as if the Company had
     accounted for its stock option plan under the fair value based method of
     SFAS No. 123. The fair value of these options was estimated at the date of
     grant using a Black-Scholes options valuation model with the following
     weighted-average assumptions for fiscal 1998: risk-free interest rate from
     5.12% to 5.83%, no dividend, volatility factor of the expected market price
     of the Company's common stock of 0.65, and an expected life of the option
     of five years.

7.   WARRANTS AND STOCK OPTIONS (cont'd)

     STOCK OPTIONS (cont'd)

     The Black-Scholes options valuation model was developed for use in
     estimating the fair value of traded options that have no vesting or trading
     restrictions and are fully transferable. In addition, option valuation
     models require the input of highly subjective assumptions including the
     expected stock price volatility. The Company's employee stock options have
     characteristics significantly different from those of traded options.
     Changes in the subjective assumptions can materially affect the fair value
     estimate.

     For the purposes of pro forma disclosure, the estimated fair value of the
     options of $59,141 (1997 - $376,394) is expensed when the options are
     granted as the options are fully vested when granted. The Company's pro
     forma information for fiscal 1998 and 1997 follows:

9.   EARNINGS PER SHARE

     In February 1997, Statement of Financial Accounting Standards No. 128,
     "Earnings Per Share," (SFAS No. 128) was issued. In accordance with SFAS
     No. 128, the Company has adopted the new standard in the quarter ended
     December 31, 1997 and for the year ended June 30, 1998. SFAS No. 128
     requires dual presentation of basic and diluted earnings per share (EPS) on
     the face of the consolidated statement of operations, and a reconciliation
     of the components of the basic and diluted EPS calculations in the notes to
     the financial statements. Basic EPS excludes dilution and is computed by
     dividing net income (loss) by the weighted average number of shares
     outstanding. Diluted EPS reflects potential dilution that would occur if
     securities or other contracts to issue common stock were exercised or
     converted into common stock. The following is the reconciliation of EPS for
     fiscal 1998, 1997 and 1996:

10.  CONTINGENCIES AND COMMITMENTS

   (a)  COPPER PURCHASE AGREEMENT

     The Company had formerly entered into a Copper Purchase Agreement relating
     to the copper output of the Sanchez Project. After sale of the Sanchez
     Project, the Company was informed that it was in alleged violation of this
     agreement. A lawsuit was filed against the Company by AIOC Corporation
     (AIOC). The Company agreed to binding arbitration with AIOC and received a
     dismissal of the lawsuit on February 8, 1996, under terms of the
     Stipulation and Order of Compromise and Dismissal.

     Under the terms of the Company's Stipulation and Order of Compromise and
     Dismissal with AIOC, the Company placed $4,000,000 into escrow to satisfy
     any award in the arbitration. During the year ended June 30, 1998, the
     Company settled the dispute and paid $400,000 to AIOC. This amount has been
     recorded as a legal expense. The remaining deposit with interest held in
     escrow has been refunded to the Company.

   (b)  EMPLOYMENT AGREEMENTS

     The Company has entered into agreements with five officers and two
     directors. The agreements provide that if there is a change in control of
     the Company and the officer leaves the employment of the Company, for
     whatever reason (other than discharge for cause, death, or disability)
     within six months after such acquisition of control, the officer shall
     receive a lump sum cash payment pursuant to certain limitations of the
     Internal Revenue Code. In addition, the officers will continue to be
     covered by all of the Company's medical, health, life, and dental plans for
     24 months after such change of control. The directors shall receive a lump
     sum cash payment in the amount not to exceed $100,000.

     In addition, the Company has entered into separate management agreements
     with its President and its Executive Vice-President. These agreements were
     effective February 1, 1998 for a term of 36 months, and provide that in the
     event of termination or failure to renew, the officer will receive a
     termination fee equal to the sum of:

(i)  buy-out of any outstanding stock options at the average market price of the
     Company's shares and less the exercise price, or at the officer's election
     and subject to regulatory approval, extension of the option for a year
     after termination

(ii) greater of the aggregate remaining base fee for the unexpired remainder of
     the term, or an annual base fee plus one month of base fee for each year of
     service after the effective date of the agreement.

     During the year ended June 30, 1998, the Company paid $304,000 in
     management fees to companies controlled by directors. This amount has been
     recorded as salaries expense.

10.  CONTINGENCIES AND COMMITMENTS (cont'd)

   (c)  PUBLIC RELATIONS AGREEMENT

     On April 1, 1998, the Company entered into an agreement with the Wall
     Street Group to provide financial public relations services to the Company.
     Pursuant to the terms of the agreement, the Company will pay a monthly cash
     fee of $5,000 and has granted a five-year stock option on 84,000 common
     shares of the Company at $1.20 per share. If the agreement is not cancelled
     or modified after 12 months, the same terms will apply for the next 12
     months, except that an additional five-year stock option on as many common
     shares as can be purchased for $100,000 will be granted, with an exercise
     price equal to the closing bid price on April 1, 1999. Each year
     thereafter, this additional stock option grant and formula will be
     maintained until the agreement is cancelled or modified.

   (d)  LEASE COMMITMENTS

     The Company is obligated under a long-term operating lease for its office
     space in Vancouver, British Columbia, through April 1999. The lease
     contains a renewal option of five years. The Company was required to
     provide a letter of credit in the amount of $16,165 at June 30, 1998. The
     letter of credit is collateralized by a term deposit of $16,165, which is
     recorded in financial statements as restricted cash. The Company has also
     leased office space in the U.S. and the United Kingdom. The aggregate
     annual rental commitment under the leases is as follows:

                    163,100
                    =======
</TABLE>

     Rental expense, net of sublease income, for the years ended June 30, 1998,
     1997 and 1996 was $60,514, $68,121 and $69,140, respectively.


11.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of cash and cash equivalents and restricted cash
     approximated fair value as of June 30, 1998 and 1997 because of the
     relatively short maturity of these instruments. It is not practicable to
     estimate the fair value of advances to OAL because the ultimate recovery of
     the advances is dependent on the ability of OAL to realize its exploration
     and development assets, which are subject to the measurement uncertainty
     inherent in such assets.

12.  SUBSEQUENT EVENTS

     (a)  On July 21, 1998, the Company entered into an option agreement with
          Cortez whereby the Company was granted an option to earn up to a 70%
          interest in the La Adelita property in Sonora, Mexico under the
          following terms:

          (i)  by subscribing to 100,000 common shares of Cortez at Cdn. $0.25
               per share

          (ii) by making option payments and paying finder's fees on behalf of
               Cortez totalling $165,000 over the next five years

          (iii) by incurring exploration expenditures on the property totalling
               $500,000 over the next three years.

     (b)  On August 6, 1998, the Company approved the repurchase of up to
          1,284,024 shares of its issued and outstanding common stock on the
          American Stock Exchange commencing August 13, 1998 and continuing up
          until August 13, 1999. The maximum authorized repurchase price is U.S.
          $1.50 per common share.


     13.  FOURTH QUARTER CHARGES

     During the fourth quarter of fiscal 1998, the Company recorded additional
     compensation expense of $119,230 related to the accounting of stock options
     granted to non-employees under SFAS No. 123. The Company recorded a tax
     benefit of $216,000 for additional tax recoveries estimated. In addition,
     the Company wrote off $370,505 in refundable deposits held by the
     Indonesian government due to the uncertainty of recoverability.


     14.  NEW PRONOUNCEMENTS

     The Financial Accounting Standards Board has issued Statement of Financial
     Accounting Standards No. 130, "Reporting Comprehensive Income," Statement
     of Financial Accounting Standards No. 131, "Disclosures About Segments of
     an Enterprise and Related Information," and Statement of Financial
     Accounting Standards No. 133, "Accounting for Derivative Instruments and

     statements. SFAS No. 130 and 131 are effective for fiscal years beginning
     after December 15, 1997 and SFAS No. 133 is effective for fiscal years
     beginning after June 15, 1999.

and its personnel shall be made party. The Consultant and its personnel (the
"Indemnified Party") shall be indemnified and funded on a current basis for all
losses, damages, legal expenses, and any other expenses or costs of any nature
which may be occasioned by their service with the Company. Inter alia, this
indemnity shall apply to all manner of actions, proceedings, or prosecutions,
whether civil, regulatory, or criminal, to which the Indemnified Party may be
subject due in whole or in part to the Services provided herein or by virtue of
any office held. This indemnity shall apply both during and after its Term for
all matters arising during the Term, and any extension, until any limitation
period has expired in respect to any action which might be contemplated. The
Company shall not refuse coverage for any purpose or reason and a strict
presumption of innocence shall be applied and the Company may only seek refund

such court approvals for the within indemnity as the Indemnified Party may

<PAGE>   9
                                      -9-

accounts of counsel as they come due and such accounts shall be rendered in the
name of the Company and, further, should the Company fail to pay any reasonable
account, it shall attorn to all such actions, summary judgments, and garnishing
orders as such counsel may consider fit to enforce and receive payment of its
account. The Company shall not seek to settle or compromise any action without
the approval of the Indemnified Party. The Company warrants it shall employ due
diligence and good faith and seek the best interests of the Indemnified Party as
defendants in any action or prosecution. The Indemnified Party shall permit the
Company to consult with their counsel and to be informed of any matters thereof,
subject only to any requirements for legal privilege purposes.


8.2 CLAIM OF INDEMNIFICATION. The Parties hereto agree to waive any right they
might have of first requiring the Indemnified Party to proceed against or
enforce any other right, power, remedy, security or claim payment from any other
person before claiming this indemnity.


8.3 NOTICE OF CLAIM. In case any action is brought against an Indemnified Party
in respect of which indemnity may be sought, the Indemnified Party will give the
Company prompt written notice of any such action of which the Indemnified Party
has knowledge. Failure by the Indemnified Party to so notify shall not relieve
the Company of its obligation of indemnification hereunder unless (and only to
the extent that) such failure results in a forfeiture of substantive rights or
defenses.

delays in transportation, breakdown of machinery, inability to obtain necessary
materials in the open market, unavailability of equipment, governmental
regulations restricting normal operations, shipping delays or any other reason
or reasons beyond the control of that Party, then the time limited for the
performance by that Party of its respective obligations hereunder shall be
extended by a period of time equal in length to the period of each such
prevention or delay.


9.2 NOTICE. A Party shall within seven calendar days give notice to the other
Party of each event of force majeure under section "9.1" hereinabove, and upon

urgency to prevent material harm to a substantive right or asset, the Parties
agree that all questions or matters in dispute with respect to this Agreement

submit any matter to arbitration pursuant to the provisions hereof, that any

the two arbitrators so named, before proceeding to act, shall, within 10
business days of the appointment of the last appointed arbitrator, unanimously
agree on the appointment of a third arbitrator, to act with them and be chairman
of the arbitration herein provided for. If the other Party shall fail to appoint
an arbitrator within 10 business days after receiving notice of the appointment
of the first arbitrator, and if the two arbitrators appointed by the Parties
shall be unable to agree on the appointment of the chairman, the chairman shall
be appointed in accordance with the Arbitration Act of the Province of British
Columbia (the "Arbitration Act"). Except as specifically otherwise provided in
this section, the arbitration herein provided for shall be conducted in
accordance with such Arbitration Act. The chairman, or in the case where only
one arbitrator is appointed, the single arbitrator, shall fix a time and place
for the purpose of hearing the evidence and representations of the Parties, and
he shall preside over the arbitration and determine all questions of procedure
not provided for by the Arbitration Act or this section. After hearing any
evidence and representations that the Parties may submit, the single arbitrator,
or the arbitrators, as the case may be, shall make an award and reduce the same
to writing, and deliver one copy thereof to each of the Parties. The expense of
the arbitration shall be paid as specified in the award.


10.4 AWARD. The Parties agree that the award of a majority of the arbitrators,
or in the case of a single arbitrator, of such arbitrator, shall be final and
binding upon each of them.

only to any requirements for legal privilege purposes.


8.2        CLAIM OF INDEMNIFICATION. The Parties hereto agree to waive any right
they might have of first requiring the Indemnified Party to proceed against or
enforce any other right, power, remedy, security or claim payment from any other
person before claiming this indemnity.


8.3        NOTICE OF CLAIM. In case any action is brought against an Indemnified
Party in respect of which indemnity may be sought, the Indemnified Party will
give the Company prompt written notice of any such action of which the
Indemnified Party has knowledge. Failure by the Indemnified Party to so notify
shall not relieve the Company of its obligation of indemnification hereunder
unless (and only to the extent that) such failure results in a forfeiture of
substantive rights or defenses.



                                   ARTICLE IX

                                  FORCE MAJEURE


9.1        EVENTS. If either Party hereto is at any time either during this
Agreement or thereafter prevented or delayed in complying with any provisions of
this Agreement by reason of strikes, walk-outs, labour shortages, power
shortages, fires, wars, acts of God, earthquakes, storms, floods, explosions,
accidents, protests or demonstrations by environmental lobbyists or native
rights groups, delays in transportation, breakdown of machinery, inability to
obtain necessary materials in the open market, unavailability of equipment,

other reason or reasons beyond the control of that Party, then the time limited
for the performance by that Party of its respective obligations hereunder shall
be extended by a period of time equal in length to the period of each such
prevention or delay.


9.2        NOTICE. A Party shall within seven calendar days give notice to the
other Party of each event of force majeure under section "9.1" hereinabove, and
upon cessation of such event shall furnish the other Party with notice of that

                                   ARBITRATION


10.1       MATTERS FOR ARBITRATION. Except for matters of indemnity or in the
case of urgency to prevent material harm to a substantive right or asset, the
Parties agree that all questions or matters in dispute with respect to this
Agreement shall be submitted to arbitration pursuant to the terms hereof. This
provision shall not prejudice a Party from seeking court order or assistance to
garnish or secure sums or to seek summary remedy for such matters as counsel may
consider amenable to summary proceedings.


10.2       NOTICE. It shall be a condition precedent to the right of any Party
to submit any matter to arbitration pursuant to the provisions hereof, that any
Party intending to refer any matter to arbitration shall have given not less
than 10 business days' prior written notice of its intention to do so to the
other Party together with particulars of the matter in dispute. On the
expiration of such 10 business days the Party who gave such notice may proceed
to refer the dispute to arbitration as provided for in section "10.3"
hereinbelow.


10.3       APPOINTMENTS. The Party desiring arbitration shall appoint one
arbitrator, and shall notify the other Party of such appointment, and the other
Party shall, within 10 business days after receiving such notice, appoint an
arbitrator, and the two arbitrators so named, before proceeding to act, shall,
within 10 business days of the appointment of the last appointed arbitrator,
unanimously agree on the appointment of a third arbitrator, to act with them and
be chairman of the arbitration herein provided for. If the other Party shall
fail to appoint an arbitrator within 10 business days after receiving notice of
the appointment of the first arbitrator, and if the two arbitrators appointed by
the Parties shall be unable to agree on the appointment of the chairman, the
chairman shall be appointed in accordance with the Arbitration Act of the
Province of British Columbia (the "Arbitration Act"). Except as specifically
otherwise provided in this section, the arbitration herein provided for shall be
conducted in accordance with such Arbitration Act. The chairman, or in the case
where only one arbitrator is appointed, the single arbitrator, shall fix a time
and place for the purpose of hearing the evidence and representations of the
Parties, and he shall preside over the arbitration and determine all questions
of procedure not provided for by the Arbitration Act or this section. After
hearing any evidence and representations that the Parties may submit, the single
arbitrator, or the arbitrators, as the case may be, shall make an award and
reduce the same to writing, and deliver one copy thereof to each of the Parties.
The expense of the arbitration shall be paid as specified in the award.


10.4       AWARD. The Parties agree that the award of a majority of the
arbitrators, or in the case of a single arbitrator, of such arbitrator, shall be
final and binding upon each of them.

whatsoever, in which case the date of receipt shall be the date on which the

        WHEREAS IN CONSIDERATION of the payments to be made pursuant to, the
mutual covenants contained in, and the mutual benefits to be derived from, this
Agreement, the Sellers and Azco hereby agree as follows:


                                    ARTICLE I

                    OPTION TO PURCHASE AND EXPLORATION RIGHTS


1.1 GRANT OF OPTION. The Seller grants to Azco the exclusive and irrevocable
option to purchase (the "Option") all or any portion of the Property (as defined
hereinbelow). As used in this Agreement, the term "Property" shall mean the
totality of all rights related to or included in the properties described in
Schedule "A" which is attached to and by this reference incorporated into this
Agreement including, without limitation, all minerals in, on and under the
Property and the land covered by the Property. The period of the Option shall be
from the date of this Agreement to February 1, 1999 (the "Option Period"),
unless extended pursuant to section "1.5" or Article "V" hereinbelow or sooner
terminated pursuant to sections "2.4", "8.1", "8.2" or "8.3" hereinbelow.


1.2 GRANT OF EXPLORATION RIGHTS. The Seller grants to Azco the full right and
authority, during the Option Period, to enter upon the Property and to conduct
such exploration and prospecting operations, as Azco may deem appropriate, to
determine the presence, location, quantity and value of minerals contained in
the Property with the intention that Azco's initial exploration efforts will be
a systematic and scientific evaluation of the Property. Such operations may
include, but shall not be limited to, mapping, sampling, including bulk
sampling, trenching, drilling, testing, assaying and conducting environmental
studies and other geochemical and geophysical exploration methods whether now
known or in the future developed, and Azco will use its reasonably best efforts
to explore the Property in conjunction with each of those certain November 13,
1997 and November 18, 1997 letters from the County of San Benito addressed to
William Rohtert while acting as an agent on behalf of Azco, August 13, 1997
Notice of Determination filed in San Benito County, October 1, 1997 San Benito
County Reclamation Agreement and May 21, 1997 approved Benitoite Gem Mine
Reclamation Plan respecting the Property (collectively, the "Reclamation Plan"),
a copy of which entire Reclamation Plan is attached as Schedule "B" to this
Agreement, failing which Azco will use its reasonably best efforts to secure
such permits and post such additional reclamation bonds as may be necessary, in
its sole and absolute discretion, for the exploration work intended to evaluate
the economic potential of the Property. Azco may establish drill sites and
construct such roads as may be necessary to the conduct of the foregoing
activities. Subject to section "8.6" hereinbelow, Azco may also mine and remove
such amount of minerals as Azco may deem appropriate for sampling, assaying,
testing and evaluation of the Property without exercising the Option; provided
that the total amount of material processed during the Option Period does not
exceed 500 cubic yards. In addition, Azco shall have the right:


        (a)     to use all easements and all rights-of-way for ingress and
                egress to and from the Property to which the Seller may be
                entitled;



<PAGE>   4
                                      -3-



        (b)     to make use of all available facilities located on the Property;


        (c)     to obtain all permits, approvals and other federal, state and
                local governmental authorizations as Azco deems necessary to
                conduct its mineral exploration activities;


        (d)     to exercise all other rights that are or may be incidental to
                any or all of the rights granted, expressly or implicitly, to
                Azco in this Agreement; and


        (e)     to the extent Seller possesses the title and authority to grant
                it, to possess and use all or any part of the Property together
                with all easements to, across and through the Property, for the
                purpose of exploring any adjoining or nearby property owned,
                controlled or operated by Azco.


1.3 OPERATIONS. Azco agrees to conduct its operations in a manner as to not
unreasonably interfere with the operations of the Seller as contemplated in
section "1.7" hereinbelow and so long as Azco is able to fulfill the essential
purposes desired to be obtained by it in this Agreement. The Parties will
mutually discuss the location of operations of both Parties and each Party will
make reasonable attempts to notify the other Party prior to any excavation work
being conducted on the Property.


1.4 OWNERSHIP AND PROCESSING OF GEMS. The Benitoite minerals and their matrix
material mined by Azco during the Option Period (collectively, the "Minerals")
will be placed in inventory by Azco, and should Azco elect to exercise its
Option to acquire the Property all such Minerals will be absolutely conveyed to
Azco by the Seller at that time. If the Property is not purchased by Azco during
the Option Period the Minerals will be returned by Azco to the Seller forthwith.
Azco will, during the Option Period and subject to the following restrictions,
maintain the sole and absolute right to process any such Minerals in any manner
it may determine reasonable in the circumstances, provided that, at all times,
any such process reasonably complies with standard industry practices in
connection with the preparation of polished goods and, provided further, that
Azco uses its reasonably best efforts to seek the maximum yield in connection
with any such Minerals. In this regard it is hereby also expressly acknowledged
and agreed by the Parties hereto that, during the Option Period, any facetable
stone greater than six carats in weight or any specimen exceeding U.S. $5,000 in
wholesale value, will only be processed in such a manner as may be mutually
agreed by both Parties, from time to time, acting reasonably. All such stones or
specimens will be kept in a mutually acceptable storage facility with a dual key
access, of which each Party will hold one key.


1.5 COOPERATION BY THE SELLER AND ASSESS TO THE PROPERTY. During the Option
Period the Seller agrees to cooperate with Azco in Azco's investigation of the
Property by consulting with Azco with respect to the Property and Azco's
possible 



<PAGE>   5
                                      -4-



operations on the Property. The Seller further agrees to use its reasonably best
efforts to assist Azco in the exercise of all rights that are or may be
incidental to any or all of the rights granted, expressly or implicitly, to Azco
in this Agreement including, without limitation, the necessary securement of all
easements and all rights-of-way for ingress and egress to and from the Property
presently available to the Seller; provided, however, that, notwithstanding the
Seller's reasonably best efforts as aforesaid, the Seller does not hereby
warrant or guarantee the availability of any said easements and rights-of-way to
Azco from third parties who previously may have permitted said use or assess to
the Seller. The Seller also agrees to use its reasonably best efforts to assist
Azco with the provision of basic technical, gemological and legal and historical
information and support which may assist Azco in its evaluation of the Property.


1.6 NON-REFUNDABLE PAYMENT. Immediately upon the receipt by Azco of its
requisite Insurance and Certificate of Qualification in accordance with sections
"4.2" and "4.4" hereinbelow and, in any event, on or before 20 days from the due
and complete execution of this Agreement, Azco shall pay to the Seller the sum
of U.S. twenty thousand dollars (U.S. $20,000) as a non-refundable payment which
may not be applied as against the purchase price of the Option in conjunction
with section "2.2" hereinbelow.


1.7 SELLER'S CONTINUED OPERATIONS. Notwithstanding the powers, rights and
authorities granted to Azco in section "1.2" hereinabove, the Seller shall have
the right to conduct operations on the Property under the following conditions:


        (a)     the Seller may conduct mining operations on the Property over a
                combined 30-day period between January 1, 1998 and May 1, 1998,
                it being acknowledged and agreed that said combined 30-day
                period shall not include those number of days that it may
                require the Seller to first set up its respective mining
                equipment and machinery on the Property, to repair any such
                mining equipment and machinery on the Property and to complete
                certain site preparation work in respect of its proposed mining
                operations on the Property; provided, however, that any said set
                up, repair and site preparation work does not require more than
                a combined 30 days to complete; and


        (b)     the Seller's operations shall be limited to the mining of a
                maximum of 1,000 cubic yards of material processed.


                                   ARTICLE II

advance and in writing by the Parties hereto, on the day of Closing. As soon as
conveniently possible after the due and complete execution of this Agreement the
Seller shall execute and deliver to Devlin Jensen, or to such other mutually
acceptable escrow agent (the "Escrow Agent") as may be agreed to in advance and
in writing by the Parties hereto, all such documents, resolutions and
instruments as may be necessary, in the opinion of solicitors for Azco, acting
reasonably, to transfer title to the Property to Azco free and clear of all
title defects, liens and encumbrances (collectively, the "Transfer Documents"),
there to be held in escrow by the Escrow Agent until the day of Closing as
provided for herein. At the Closing the following shall occur:


        (a)     the Escrow Agent shall deliver to Azco the Transfer Documents;


        (b)     Ad valorem, property and other taxes and assessments imposed
                upon the Property shall be prorated between the Seller and Azco
                as of the date of Closing and the Seller shall be charged for
                all such taxes and assessments prior to the day of Closing; and


        (c)     the Parties shall execute and deliver such other documents and
                shall take such other action as may be necessary to carry out
                their obligations under this Agreement.


        Without in any manner limiting the extent of the foregoing, it is hereby
acknowledged and agreed by the Parties hereto that if Azco exercises the Option
in accordance with the terms of this Agreement then Azco shall, without any
further act, have acquired all of the Seller's right, entitlement and interest
in and to the Property.


2.4 NON-EXERCISE OF OPTION. Notice of waiver to the Seller or the failure of
Azco to dispatch a notice prior to the expiration of the Option Period will
constitute an irrevocable waiver of the Option and the Parties thereafter will
be released from the terms of this Agreement, except that Azco shall have the
rights contained in section "8.4"

                                      -6-

        (c)     Azco shall have quiet and peaceful possession of the Property;

                lien to be placed against the Property.


3.2 TITLE DEFECTS. If title to any of the Property is less than as warranted in
section "3.1" hereinabove, Azco may undertake to cure any such defects or to
defend or to initiate litigation to perfect, defend or cure title to the
Property. Azco, at any time, may withdraw from or discontinue any title
litigation or any steps it may have taken to perfect, defend or cure title. Azco

discontinues title litigation or other curative work. The Seller agrees to
cooperate fully with Azco in any and all steps undertaken by Azco to remedy
title defects.


                                   ARTICLE IV

                                      -7-



4.1 STANDARD OF PERFORMANCE. Azco shall cause all exploration work to be done in
a careful, safe and good miner-like manner, and to conform in all respects to
applicable governmental rules, regulations and statutes; provided, however, that
Azco may use any method it deems reasonable, including experimental or
innovative methods, in sampling, evaluating and recovering minerals from the
Property in exercising the rights granted in section "1.2" hereinabove, and
shall not be liable to the Seller in any way if such methods do not result in
full recovery of the minerals being evaluated, or full maximization of the value
thereof. Further, Azco shall conduct its operations under this Agreement in a
manner that will not unreasonably damage the surface of the Property and, in the
event the Option is not exercised, shall reclaim, in accordance with applicable
rules, regulations and statutes, all portions of the surface of the Property
that it has disturbed by its operations.


4.2 INDEMNIFICATION AND INSURANCE. Azco shall assume all liability to third
parties in connection with its exploration on the Property and, except as
provided in section "6.1" hereinbelow, shall indemnify the Seller against any
and all liability that may arise out of Azco's operations on the Property. Azco
shall, at all times during the continuance of this Agreement, at its sole cost
and expense, procure and maintain in full force and effect a policy or policies
of comprehensive public liability insurance issued by an insurer which is
acceptable to the Seller, such approval not to be unreasonably withheld,
insuring against loss, damage or liability for injury to or death of persons or
loss or damage to property occurring upon the Property in an amount of not less
than U.S. one million dollars (U.S. $1,000,000) for each person injured or
killed, and not less than U.S. one million dollars (U.S. $1,000,000) for
property damage. Said policy or policies of insurance shall name Azco and the
Seller as insured as their respective interests may appear. Azco shall also,
again at all times during the continuance of this Agreement, at its sole cost
and expense, procure and maintain in full force and effect worker's compensation
insurance and such other insurance to cover personnel and all of their
operations upon the Property in an amount and form as may be required by law;
and Azco shall comply with all laws and regulations pertaining to the
performance of work on the Property. Copies of all insurance policies provided
for herein shall be furnished to the Seller when purchased, and Azco shall
obtain a written obligation on the part of its insurance carriers to notify the
Seller in writing prior to the cancellation of any policy provided for in this
Agreement. In the event that Azco shall fail to either procure or maintain any
insurance policy required by this Agreement and such shall continue for period
of 10 days from the receipt of written notice by Azco of such failure, the
Seller may terminate this Agreement, immediately, without further obligation or
liability to Azco. Azco shall not commence any mining or exploration operations
upon the Property without procuring the insurance policies (collectively, the
"Insurance") as herein required, and shall cease all operations upon the
Property should a policy of Insurance required by this Agreement be canceled or
terminated.


4.3 PERMITS. The Seller understands that Azco may make efforts to obtain permits
and other authorization of every kind and nature whatsoever from governmental or
private entities as may be necessary to conduct mineral exploration activities.
While Azco shall be solely responsible in these efforts, the Seller agrees to
assist and cooperate fully with Azco in any and all such endeavors upon Azco's
request.

4.4 CERTIFICATE OF QUALIFICATION. Prior to the commencement of any operations or
activities upon the Property Azco shall obtain a "Certificate of Qualification"
authorizing it to transact intra-state business in California, as provided for
in sections 2105 et seq. of the California Corporations Code, and Azco shall
provide the Seller with a copy thereof. Azco shall additionally notify the
Seller in writing forthwith should such Certificate of Qualification be
surrendered or should Azco be disqualified in any manner from doing business in
the State of California. All operations and activities of Azco shall cease
during any period of disqualification.


4.5 LIENS, TAXES. During the Option Period Azco shall keep the title to the
Property free and clear of all valid liens and encumbrances resulting from its
exploration operations under this Agreement and shall pay when due all taxes and
assessments attributable to its operations under this Agreement or imposed upon
any property or improvements placed by Azco on the Property for its own use.
Azco may refuse to pay and may contest any claim, taxes or assessments asserted
against or imposed upon it that it disputes in good faith, but shall not permit
all or any portion of the Property to sold at any time for such taxes or
assessments. If the claim is finally resolved against Azco or the taxes or
assessments are finally determined to be valid, Azco shall pay the same upon
such final determination.


4.6 SUBROGATION. Azco, at its option, shall have the right to redeem for the
Seller, by payment of any mortgage, taxes or other liens on the Property in the
event of default or non-payment by the Seller. If Azco pays any such mortgage,
taxes or other liens Azco shall be subrogated to rights of the holder of the
mortgage or lien and may deduct any amount so paid from any payment due to the
Seller under this Agreement. Further, if Azco exercises the Option Azco shall
have the right to retain and repay itself from the referenced purchase price.


4.7 NO IMPLIED COVENANT. Azco does not make any express or implied covenant,
agreement or condition relating to the exploration of the Property. Whether or
not any such exploration shall at any time be conducted, and the nature, manner
and extent of such operations, shall be determined by Azco in its sole and
absolute discretion.


                                    ARTICLE V

                                  FORCE MAJEURE


5.1 DEFINITION OF FORCE MAJEURE. The Option Period and the time for removal of
equipment pursuant to section "8.4" hereinbelow shall be extended for a period
of time equivalent to the period or periods of force majeure. The term "force

5.2 REMOVAL OF EVENT OF FORCE MAJEURE. Azco shall exercise reasonable diligence
to remove an event of force majeure as quickly as possible, but shall not be
required to settle strikes, lock-outs or other labor difficulties contrary to
its wishes, accept unusual or onerous permit conditions, or to challenge the
validity of any governmental order, request, law or regulation.


                                   ARTICLE VI

                         INSPECTION AND CONFIDENTIALITY


6.1 INSPECTION. During the continuance of this Agreement the Seller and its
respective representatives shall have the right to enter onto the Property,
without the written permission of or notice to Azco, to inspect the Property and
to protect, exercise or investigate any rights of the Seller under this
Agreement; provided, however, that the Seller shall not unreasonably hinder or
interrupt the operations and activities of Azco during any such time of
inspection. The Seller shall inspect such operations at its own risk and expense
and shall indemnify Azco, and its affiliated and direct and indirect parent
corporations and their respective directors, partners, officers, employees,
agents and corporate affiliates, from and against any loss, damage, claims or
demand by reason of injury to or the presence of the Seller, its agents,
representatives, licensees or guests arising from such inspection.


6.2 REPORTS. Each Party shall provide the other with quarterly reports
summarizing activities on the Property and stating quantities of gems and other
materials removed from the Property.


6.3 CONFIDENTIALITY. The Seller agrees that during the Option Period and, if the
Option is exercised at all times thereafter, to treat all information acquired
under this Agreement as confidential and not to use the name of Azco in any
document or press release or disclose any information that may be obtained under
this Agreement to third parties or to the public without first having obtained
the written approval of Azco as to the form and content of any such disclosure
or release. The Seller further agrees not to use, sell, give, disclose or
otherwise make available to third parties or to the public at any time any
knowledge or information that the Seller may obtain relating to internal
proprietary techniques and methods used by Azco.


                                   ARTICLE VII

                      ASSIGNMENT AND RIGHT OF FIRST REFUSAL



<PAGE>   11
                                      -10-



7.1 ASSIGNMENT BY THE SELLER. The Seller shall not assign any right or interest
in the Property or this Agreement during the Option Period.


7.2 ASSIGNMENT OR TRANSFER BY AZCO. Azco shall have the right at any time to
assign or transfer all or any portion of its rights under this Agreement;
provided, however, that prior to any such assignment or transfer Azco shall
first provide the Seller with an accurate and detailed statement of the proposed
assignee's or transferee's financial background and expertise in the mining
industry; with the Seller thereby maintaining the right to approve any such
assignee or transferee, such consent not to be unreasonably withheld.


                                  ARTICLE VIII

                                   TERMINATION


8.1 BY SELLER. At the election of the Seller the failure of Azco to make or
cause to be made any of the payments required by this Agreement or to keep or
perform any covenant on its part to be kept or performed according to the terms
or provisions of this Agreement shall constitute an event of default. Upon an
event of default the Seller shall give to Azco written notice of default,
clearly denominated as a notice of default, specifying the particular default or
defaults relied on by it. Azco shall have a reasonable time (which in any case
shall not be less than 10 calendar days) after receipt of such notice in which
to contest, cure or commence to cure the alleged default or defaults. If Azco
contests that default occurred, it shall so advise the Seller in writing. If
Azco contests the default the matter shall be submitted to a court of competent
jurisdiction, and Azco shall not be deemed in default until the matter shall
have been determined finally by the court and all appeals have been taken or
waived. Upon Azco's failure to cure the default the Seller may declare, by
written notice to Azco, termination of this Agreement.


8.2 BY AZCO. Notwithstanding any provisions herein to the contrary, Azco may at
any time terminate and surrender this Agreement as to all or any portion of the
Property by giving written notice thereof to the Seller. Promptly thereafter
Azco shall deliver to the Seller a properly executed release of the portion of
the Property being released. Upon full or partial surrender of this Agreement
Azco shall be relieved of all obligations as to the Property or portion of the
Property being released, except obligations that have accrued prior to surrender
and the obligation to restore the surface disturbed by Azco's operations.


8.3 BANKRUPTCY OR RECEIVERSHIP BY AZCO. Azco agrees that in the event that all
or substantially all of its assets, either individually or severally, are placed
in the hands of a receiver or trustee, and such receivership or trusteeship
continues for a period of 30 days, or should Azco, either individually or
severally, make an assignment for the benefit of creditors or be adjudicated a
bankrupt, or should it, individually or severally, institute any proceedings
under any bankruptcy legislation, whether of Canada or the United States of
America, as the same now exists or under any amendments thereof which may
hereafter be enacted, then this Agreement or any rights granted to Azco
hereunder shall 



<PAGE>   12
                                      -11-



not become an asset in any such proceedings, and the Seller, at the Seller's
option, may terminate this Agreement and Azco shall have no further rights
hereunder.


8.4 REMOVAL OF EQUIPMENT. Upon termination of this Agreement, except upon Azco's
exercise of the Option, Azco shall have three months after termination to remove
from the Property all buildings, improvements, equipment and all personal
property of every kind and nature erected or placed in or upon the Property by
it. If Azco is hampered by force majeure, as defined in Article "V" hereinabove,
the time for removal shall be extended by the period of force majeure. Any such
property not removed within the time provided in this section shall become the
sole property of the Seller, and Azco shall have no further right, title or
interest with respect to it; provided, however, that Azco shall remain liable
for all unpaid taxes, liens and encumbrances on such removal property and shall
indemnify the Seller for the cost of removal of any such buildings,
improvements, equipment and personal property.


8.5 OBLIGATION UPON TERMINATION. Upon termination of this Agreement pursuant to
either sections "2.4", "8.1" or "8.3" hereinabove Azco shall be under no further
obligation or liability under this Agreement to the Seller from and after the
date of termination, except for the following:


        (a)     Azco shall perform obligations and satisfy liabilities to the
                Seller or third parties respecting the Property that have
                accrued prior to the date of termination and resulted, directly
                or indirectly, from Azco's operations hereunder;


        (b)     Azco shall restore the surface of the Property pursuant to
                section "4.1" hereinabove and Article "X" hereinbelow resulting
                from Azco's activities thereon; and


        (c)     Azco shall furnish to the Seller one set of all information and
                data in Azco's possession relating to the quantity and quality
                of minerals which Azco has not already provided under Article
                "VI" hereinabove.


         Azco shall not be obligated, however, to furnish to the Seller
interpretative data or reports or internal proprietary information. Any use or
reliance by the Seller upon the data provided by Azco shall be at the Seller's
sole risk and Azco makes no express or implied representations or warranties
with respect thereto.


8.6 RETURN OF PRODUCTS. If Azco does not exercise the Option, or if the Option
is otherwise terminated in accordance with the terms of this Agreement, Azco
will forthwith return to the Seller all gemstones remaining in its possession
taken from the Property, whether cut or uncut, together with any processed or
unprocessed rock, drill core or cuttings in its possession taken from the
Property.

8.7 ATTORNEY'S FEES AND COSTS. If any legal action, including arbitration or
mediation, is brought to enforce or interpret this Agreement, the prevailing
Party hereto shall be entitled to recover reasonable attorney's fees and costs
of the action in addition to any other relief granted in any such proceedings.


                                   ARTICLE IX

                                   ARTICLE XI

                                 INDEMNIFICATION


11.1 INDEMNIFICATION. The Parties hereto agree to indemnify and save each other
Party hereto, including their respective affiliates and their respective
directors, officers, employees and agents (each such party being an "Indemnified
Party") harmless from and against any and all losses, claims, actions, suits,
proceedings, damages, liabilities or expenses of whatever nature or kind,
including any investigation expenses incurred by any Indemnified Party, to which
an Indemnified Party may become subject by reason of the terms and conditions of
this Agreement.


11.2 NO INDEMNIFICATION. This indemnity will not apply in respect of an
Indemnified Party in the event and to the extent that a court of competent
jurisdiction in a final judgment shall determine that the Indemnified Party was
grossly negligent or guilty of willful misconduct.


11.3 CLAIM OF INDEMNIFICATION. The Parties hereto agree to waive any right they
might have of first requiring the Indemnified Party to proceed against or
enforce any other right, power, remedy, security or claim payment from any other
person before claiming this indemnity.


11.4 NOTICE OF CLAIM. In case any action is brought against an Indemnified Party
in respect of which indemnity may be sought against any of the Parties hereto,
the Indemnified Party will give relevant Party hereto prompt written notice of
any such action of which the Indemnified Party has knowledge and such Party will
undertake the investigation and defense thereof on behalf of the Indemnified
Party, including the prompt employment of counsel acceptable to the Indemnified
Parties affected and the payment of all expenses. Failure by the Indemnified
Party to so notify shall not relieve any Party hereto of such Party's obligation
of indemnification hereunder unless (and only to the extent that) such failure
results in a forfeiture by any Party hereto of substantive rights or defenses.


11.5 SETTLEMENT. No admission of liability and no settlement of any action shall
be made without the consent of each of the Parties hereto and the consent of the
Indemnified Parties affected, such consent not to be unreasonable withheld.


11.6 LEGAL PROCEEDINGS. Notwithstanding that the relevant Party hereto will
undertake the investigation and defense of any action, an Indemnified Party will
have the right to employ separate counsel in any such action and participate in
the defense thereof, 



<PAGE>   15
                                      -14-


but the fees and expenses of such counsel will be at the expense of the
Indemnified Party unless:


        (a)     employment of such counsel has been authorized by the relevant
                Party hereto; or


        (b)     the relevant Party hereto has not assumed the defense of the
                action within a reasonable period of time after receiving notice
                of the action; or


        (c)     the named parties to any such action include that any Party
                hereto and the Indemnified Party shall have been advised by
                counsel that there may be a conflict of interest between any
                Party hereto and the Indemnified Party; or


        (d)     there are one or more legal defenses available to the
                Indemnified Party which are different from or in addition to
                those available to any Party hereto.


11.7 CONTRIBUTION. If for any reason other than the gross negligence or bad
faith of the Indemnified Parties (or any of them) being the primary cause of the
loss claim, damage, liability, cost or expense, the foregoing indemnification is
unavailable to the Indemnified Parties (or any of them) or insufficient to hold
them harmless, the relevant Parties hereto shall contribute to the amount paid
or payable by the Indemnified Parties as a result of any and all such losses,
claim, damages or liabilities in such proportion as is appropriate to reflect
not only the relative benefits received by any Party hereto on the one hand and
the Indemnified Parties on the other, but also the relative fault of the parties
and other equitable considerations which may be relevant. Notwithstanding the
foregoing, the relevant Party or Parties hereto shall in any event contribute to
the amount paid or payable by the Indemnified Parties, as a result of the loss,
claim, damage, liability, cost or expense (other than a loss, claim, damage,
liability, cost or expenses, the primary cause of which is the gross negligence
or bad faith of the Indemnified Parties or any of them), any excess of such
amount over the amount of the fees actually received by the Indemnified Parties
hereunder.

                                     GENERAL

                              CONVERTIBLE DEBENTURE
                              ---------------------
                                (the "Debenture")



PRINCIPAL:                 $1,500,000 (U.S.)

INTEREST:                  12% PER ANNUM

DUE DATE:                  SEPTEMBER 1, 2000



WITH THE TERMS AS FOLLOWS:


FOR VALUE RECEIVED, ORO ARGENTINA LIMITED (the "Company"), a company having its
address for service of all notices and process hereto located as stated above,
HEREBY ACKNOWLEDGES ITSELF INDEBTED TO AZCO MINING INC. (the "Lender"), a
company duly incorporated under the laws of Delaware and having an address for
notices and service at Suite 1250, 999 West Hastings Street, Vancouver, British
Columbia, AND THE COMPANY PROMISES TO PAY TO THE LENDER, in the manner and at
the times set forth herein in accordance with the stated terms, the AGGREGATE
PRINCIPAL (the "Principal", also called the "Loan") sum of ONE MILLION FIVE
HUNDRED THOUSAND DOLLARS ($1,500,000 U.S.) AND INTEREST , AND OTHER COSTS AS SET
FORTH HEREIN, in lawful money of the United States of America.


The effective date (the "Effective Date") of this Debenture shall be May 22,
1998 and the due date (the "Due Date") for the payment of all unpaid Principal
and Interest shall be September 1, 2000, unless accelerated due to default not
cured or waived by the terms hereof, and such accelerated date shall thereupon
be the Due Date.



                             -- Senior Debenture --


<PAGE>   2

                                      -2-


This Debenture is specifically acknowledged to be a continuing security for all
indebtedness of the Company outstanding from time-to-time, including for all
re-advances after any payments of Principal, partial or otherwise, until
discharged by the Lender in writing.


1.       INTEREST

         This Debenture will bear interest (the "Interest") at TWELVE (12%)
PERCENT PER ANNUM, calculated and payable annually. After the Due Date Interest
shall continue at 12% per annum but shall be calculated monthly and payable
monthly until payment in full of Principal and Interest. In the event the Lender
elects to extend the Due Date at request of the Company, the Interest accrued
shall be compounded to Principal and such compounded amount shall thereafter be
deemed Principal and shall accrue Interest until the deferred Due Date.


2.       PAYMENT OF PRINCIPAL AND INTEREST

         The Principal, and Interest accrued thereon, will be due and payable by
the Company to the Lender in the following manner:

         (a)      Interest will be payable annually and on the Due Date, or any
                  acceleration thereof, and any payments on this Loan shall be
                  applied firstly to Interest;

         (b)      the Principal shall be paid on the Due Date, and any
                  acceleration thereof; and

         (c)      in the event that the Principal and Interest has been reduced
                  by an exercise of the Conversion Option (as defined below)
                  then the Interest calculation and the Principal payment
                  calculations shall be adjusted appropriately.


3.       CONVERSION TERMS OF THIS DEBENTURE

         The Lender shall have the option during the term of this Debenture, and
any extension thereto, to convert (the "Conversion Option") the Principal and
Interest unpaid into common units (the "Units") of the Company at a conversion
rate of FIFTY CENTS ($0.50) (US) per Unit, adjusted as to number and price of
Units for any consolidation or sub-division of the Company's capital. Each Unit
shall be composed of one share and one warrant, of which each warrant shall
permit the purchase of an additional common share at a price of sixty cents
($0.60) (US) at any time from the exercise of the Conversion Option to two years
thereafter.

The Lender shall have the right, at any time during the period of the Conversion
Option, to require conversion of this Debenture into Units, which right shall
supersede any tender by the Company for payment of this Debenture in cash.



                                 -- Debenture --
<PAGE>   3

                                      -3-


         Fractional shares will not be issued on any conversion but, in lieu
thereof, the Company will make a cash payment.

         The right to convert the Debenture may be exercised by the Lender by
the delivery of a notice setting forth the amount of the Conversion Option being
exercised. If the Lender exercises less than the full amount of Principal and
Interest outstanding, then this Debenture shall continue to secure any amounts
remaining unpaid. Subject to regulatory delays reasonably acceptable to the
Lender, the Units shall be delivered within ten (10) days of notice of exercise
and subject to the least restriction available under appropriate regulatory
laws. In the event that the Units are subject to a hold period, the Company
shall qualify the same with any prospectus being issued by the Company but if
any hold period is greater than one year, the Company shall qualify the same by
prospectus at the demand of the Lender and at the Company's cost.


4.       FIRST CHARGE AND FURTHER SECURITY

         This Debenture shall be a first floating and fixed charge security on
the assets of the Company. The Company agrees to promptly (absent regulatory
delay, within ten (10) days of demand) provide further and other security as the
Lender may require including, without restricting the generality, specific
charge security on specific assets of the Company, such as a pledge of
subsidiary shares of the Company.

         It is acknowledged by the Lender that the Company is issuing an
additional debenture in the amount of $100,000 US having the same terms (other
than loan amount and conversion rate) as this Debenture and ranking pari passu
and pro rata with this Debenture. The Lender consents to the issue of such
additional debenture. The Company shall not issue any further loans or other
security whatsoever, whether superior, pari passu, or inferior to this
Debenture, without the written permission of the Lender, which permission may be
with held without reason.

5.       REDEMPTION RIGHTS

         The Company, with the Lender's prior permission (which may be refused
without cause) and subject to the lender's right to exercise the Conversion
Option, may, in the manner hereinafter set forth, pay any amount of outstanding
Principal, and any Interest accrued, without bonus or penalty.

         Should the Company elect to pre-pay the Loan it shall request
permission of the Lender thirty (30) days' prior to its intention to redeem and
repay all or any portion of the Principal and any Interest accrued thereon which
would be unpaid by the Company to the Lender at the end of such 30-day period
(such day at the end of such 30-day period being the "Redemption Date" and, for
clarity, such Redemption Date would be the date to which such Principal and
Interest would be calculated at the close of business, in Vancouver, British
Columbia, on such Redemption Date) and, thereupon, if the Lender has granted
permission, the Lender will be entitled to exercise that part of the Loan
intended to be redeemed until only noon on the business day preceding the
Redemption Date, failing which exercise by the Lender will then terminate



                                 -- Debenture --
<PAGE>   4

                                      -4-



that part of the Conversion Option. If, however, the Company fails to make the
payment of any portion of the Principal and any Interest accrued thereon to the
Lender which it previously advised it intended to make on the Redemption Date,
then the Lender will be entitled to continue to exercise the Conversion Option
as to the then balance of the Principal and Interest of the Debenture until the
Due Date or in accordance with a subsequent Redemption Date notice.


6.       FIXED CHARGE SECURITY

         Fixed Charge. As security for payment of the Principal and Interest and
all other moneys owing by the Company to and for the performance of the
obligations and other covenants of the Company, the Company hereby grants,
mortgages, pledges, charges, assigns and conveys to and in favour of the Lender
(subject to exception as to the last day of the term of any lease), as and by
way of a fixed charge, all of the interest of the Company in the assets (the
"Assets") listed in Schedule "A" hereto and hereby covenants and agrees to
cause, at the Company's cost, the within Debenture to be registered against the
Assets to the extend available in the relevant jurisdictions or, at the Lender's
sole discretion and at the cost of the Company in the event of the Company's
failure or omission to so register, hereby permits the Lender to register this
Debenture as security on and to the Assets. The Company agrees that the Lender
may register this Debenture at any time and may register the same in all
governmental or public registries as it may consider advisable and, further, to
make all such publications as the Lender may consider advisable to effect public
notice of the charge herein created (the "Fixed Charge Mortgaged Property"), all
at the cost of the Company.

         For the purposes of this Debenture, the assets to which the Fixed
Charge Mortgaged Property refer are hereinafter collectively referred to as the
"Mortgaged Property".

         The last day of any term reserved by any lease agreement is excepted
out of the Mortgaged Property and charges hereby created and does not form any
part of the Mortgaged Property; but if any sale is made under or pursuant to the
powers herein contained of any lease forming part of the Mortgaged Property the
Company will hold the same in trust for the purposes hereof to assign to any
person who may acquire such term or any part thereof.


7.       REPLACEMENT OF PRIOR ENCUMBRANCES AND RELEASE OF SECURITY

         It is hereby agreed and acknowledged by the Company and the Lender that
this security shall replace and supersede any preceding agreements and contracts
of security respecting the Principal and Interest.

         Upon payment of the Principal (whether by payment in cash or by
conversion to Shares) and payment of Interest, the Lender shall provide the
Company, at its request, with all such discharges, releases and acknowledgments
of payment as the Company may reasonably require and request to evidence such
payment and to discharge the within security and any registration in respect
thereto.

         TO HAVE AND TO HOLD the same unto and to the use of the Lender, and the
Lender's successors and assigns, upon and subject to the terms and conditions
herein set forth.


         THIS DEBENTURE IS ISSUED SUBJECT TO AND WITH THE BENEFIT OF THE
CONDITIONS ANNEXED HERETO, WHICH ARE TO BE DEEMED PART OF IT.



         IN WITNESS WHEREOF the Company has caused its duly authorized officer
to execute these terms effective on the Effective Date.

         (j)      If the Company commences disposing of, permits the loss of, or
                  is unable to maintain all or a substantial portion of its

         due and payable, but no such waiver of the Lender will extend to or
         affect any subsequent default or event or the rights resulting
         therefrom.


6.       The security hereby constituted will become enforceable if the
         Principal moneys and Interest hereby secured are not paid, or any
         conversion option not honoured, when the same become due and payable in
         accordance with the provisions herein contained.


7.       At any time after the Principal moneys hereby secured have become
         payable and remain unpaid (where the Company has failed to rectify
         default within 30 days of notice), the Lender may by instrument in
         writing appoint any person, whether an officer or employee of the
         Lender or not, to be a receiver or receiver-manager (herein called the
         "Receiver") of the Company and/or (at the Lender's sole discretion) of
         the Mortgaged Property and assets hereby charged and may remove any
         Receiver so appointed and appoint another in his stead.

         Any Receiver so appointed shall have the power:

         (a)      To take possession of, collect and get in the Mortgaged
                  Property and for that purpose to take any proceedings in the
                  name of the Company or otherwise;

         (b)      To carry on or concur in carrying on the business of the
                  Company and for that purpose to raise money on the Mortgaged
                  Property in priority to this Debenture or otherwise;

         (c)      To sell or lease or concur in the selling or leasing of the
                  whole or any part of the Mortgaged Property and to convert the
                  same or any part thereof into money, with full power to sell
                  any Mortgaged Property either together or in parcels and
                  either by public auction or private contract and either for a
                  lump sum or for a sum payable by installments or for a sum on
                  account and a mortgage or charge for the balance (and the
                  Receiver will not be accountable for any moneys until actually
                  received), and with full power upon every such sale to make
                  any special or other stipulation as to title or otherwise
                  which the Receiver may deem proper, and with full power to buy
                  in or rescind any contract for sale of the Mortgaged Property
                  or any part thereof and to resell the same without being
                  responsible for any loss which may be occasioned thereby; and

         (d)      To make any arrangement or compromise which he may think
                  expedient to the interests of the Lender.

         To enable any Receiver so appointed to exercise the powers granted to
         him by this Section 7, upon the appointment of the Receiver under this
         Section 7, the Company appoints such Receiver to be its attorney to
         effect a sale or lease of any of the Mortgaged Property by conveying or
         leasing in the name of or on behalf of the Company or


<PAGE>   9
                                      -9-

         otherwise, and under his own seal; and any deed, lease, agreement or
         other instrument signed by any such Receiver under his seal pursuant
         hereto will have the same effect as if it were under the corporate seal
         of the Company.

         It is hereby agreed and acknowledged that the Receiver may at any time
         bring an application before a court of competent jurisdiction to
         receive all orders and directions as the Receiver or the Lender may
         deem advisable for the purpose of exercising the receivership herein
         provided and for exercising all rights, powers and privileges conferred
         by this Debenture and the Company hereby attorns to all such process
         and waives any defenses thereto or any dispute regarding the power of
         the Receiver to exercise any of the powers herein granted, excepting
         only that the Company shall not be prohibited from pleading a right to
         a redemption period under the laws affecting real Mortgaged Property,
         but that such redemption period shall not exceed a period of ninety
         (90) days.

         No purchaser of any sale purporting to be made by such Receiver
         pursuant hereto will be bound to inquire whether any notice required
         hereunder has been given or otherwise as to the propriety of the sale
         or regularity of its proceedings, or be affected by notice that no
         default has been made, or continues, or notice that the sale is
         otherwise unnecessary, improper or irregular; and despite any
         impropriety or irregularity or notice thereof to any Lender, the sale
         as regards such Lender will be deemed to be within the aforesaid powers
         and be valid accordingly and the remedy (if any) of the Company in
         respect of any impropriety or irregularity whatsoever in any such sale
         will be in damages only.

         Any Receiver appointed hereby will be deemed to be the agent of the
         Company, and the Company will be solely responsible for his acts or
         defaults and for his remuneration and expenses, and the Lender will not
         be in any way responsible for any misconduct or negligence on the part
         of any such Receiver.

         All moneys received by such Receiver after providing for payment of all
         claims and charges (if any) ranking prior to this Debenture and for all
         costs, charges and expenses of or incidental to the appointment of the
         Receiver including the reasonable remuneration of the Receiver and all
         outgoings properly payable by him will be applied:

         Firstly:      In or towards payment of any costs provided by Section 8
                       hereinbelow set forth;

         Secondly:     In or towards payment to the Lender of the Principal and
                       all other moneys (other than Interest) hereby secured;

         Thirdly:      In or towards payment to the Lender of all arrears of
                       Interest remaining unpaid on this Debenture; and

         Fourthly:     The surplus (if any) will be paid to the Company.

                                      -10-



         The rights and powers conferred by this Section 7 are supplemental to
         and not in substitution for any rights and powers the Lender may from
         time to time have or a court of competent jurisdiction may confer on
         the Receiver upon his application in accordance with the laws and
         custom of the relevant jurisdiction.


8.       The Company will pay to the Lender on demand the amount of all expenses
         including, without limiting the generality of the foregoing, all legal
         fees (on a solicitor and client basis) and other costs, charges and
         expenses incurred by the Lender relating to the creation and
         registration of this Debenture or in recovering or enforcing payment of
         the moneys hereby secured, or in realizing upon this Debenture or any
         other securities for such moneys, or in taking possession of or
         protecting or realizing upon any property comprised in any such
         security, all of which together with Interest thereon at the rate
         provided for in this Debenture will be secured hereby, and in default
         of payment thereof all remedies hereunder and at law and in equity will
         be exercisable.


9.       This Debenture is to be treated as an assignable instrument.


10.      This Debenture is in addition to and not in substitution for collateral
         security and agreements now or hereafter held by the Lender, except as
         specifically elsewhere excluded by this Debenture.


11.      The security created by this Debenture is a continuing security for the
         payment of all indebtedness, both present and future, and all and every
         liability, present or future, direct or indirect, absolute or
         contingent, of the Company to the Lender.

<PAGE>   12
                                      -12-

         (b)      Become guarantor of any obligation, or become endorser in
                  respect of any obligation, or otherwise become liable upon any
                  notice or other obligation, other than in the normal course of
                  the Company's business; or

         (c)      Acquire or permit any loan, charge, claim, action, or
                  encumbrance which may jeopardize the priority of this
                  Debenture or may restrict or diminish the security of the
                  Lender in the Mortgaged Property or any asset, without the
                  permission of the Lender in writing.


15.      It is hereby specifically acknowledged by the Lender that this
         Debenture shall not restrict the Company's ability to operate its
         business in the normal course including, without limiting the
         generality, this Debenture shall not prohibit the Company from
         disposing of (except of the Mortgaged Property) or acquiring assets in
         the normal course of business, whether real property or moveable
         property, or from disposing of its products of commerce in the normal
         course of business. The Company shall not sell, or otherwise dispose
         of, all or substantially all of its business without permission of the
         Lender and subject to such conditions as the Lender may consider
         appropriate, including the application of all proceeds therefrom to
         payment of the Debenture.


16.      Until this Debenture has been discharged, this Debenture and the
         charges hereby created constitute valid and continuing security for the
         payment of any and all indebtedness owing by the Company to the Lender
         notwithstanding the temporary payment of all or any portion of the
         moneys hereby secured.


17.      Neither the taking of any judgment nor the exercise of any power of
         seizure or sale or any other rights or powers of the Lender hereunder
         will operate to extinguish the liability of the Company to make payment
         of the Principal moneys and Interest hereby secured, nor will the same
         operate as a merger of any covenant or affect the right of the Lender
         to Interest at the rate hereinbefore provided.


18.      The Lender, in addition to any other powers given to it, has the power:

         (a)      To release any property of the Company from the charge created
                  by or pursuant to this Debenture;

         (b)      To agree to any modification, compromise, release or waiver of
                  the rights of the Lender against the Company or against its
                  property, whether such rights arise under this Debenture or
                  otherwise; and

         (c)      To accept any other properties or securities in substitution
                  the Mortgaged Property of this Debenture.

RE:      AGREEMENT IN PRINCIPLE ("AIP") OF AGREEMENT DATED MAY 22, 1998

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


This amended Memorandum of Agreement, if accepted by you, will constitute an
amendment and continuance of the AIP between Azco Mining Inc. ("Azco"), Oro
Argentina Limited ("OAL"), Ronald Handford ("RH"), and Roger Trodler-Laine
"(RL"), each in accordance with the terms as set forth below.

The terms which we propose are as follows:


A.       FINANCING COMPONENT

1.       Subject to satisfactory execution by all parties of the hereafter
described agreements and approval of the boards of each of Azco and OAL, Azco
shall purchase a $750,000 US convertible debenture (the "Debenture") from OAL
and Azco shall be granted 1,500,000 warrants. Unless otherwise agreed in writing
by Azco, the proceeds of the Debenture shall be used only for the first phase of
the Chigua White Bentonite Project (the "Project"), option payments to Pierre
Martre in accordance with an option agreement (the "Option Agreement") with
Pierre Martre, and a maintenance and administrative allowance as approved by
Azco.

2.       The terms of the Debenture shall be as follows:

         (i)      the Debenture shall be a first fixed and floating charge
                  convertible debenture in the principal amount of $750,000 US
                  (the "Principal") bearing interest on outstanding Principal at
                  12% per annum, calculated and payable annually in arrears, and
                  shall mature two years from its date of issue. It shall be in
                  Azco's standard form and shall not have pre-payment privileges
                  without Azco's consent;

         (ii)     the Principal shall be drawn by OAL against approved budgets
                  and draw schedules, as mutually agreed, in accordance with the
                  approved mining and production plan (the "Production Plan");

                                      -2-


         (iii)    at the option of Azco, the Debenture shall be convertible, as
                  to Principal (and Azco may elect to advance the total
                  Principal at any time for such purpose), and outstanding
                  interest, to common shares of OAL during the term of the
                  Debenture. Azco may elect to exercise the conversion right in
                  priority to repayment of Principal and interest. Each share
                  shall be priced at $0.50 US.

3.       The 1,500,000 warrants (the "Warrants") granted to Azco concurrently
with the Debenture, shall be two year Warrants exercisable at any time to
purchase up to 1,500,000 common shares of OAL at a price of $0.60 US per share.

4.       Azco shall have the right to appoint a representative to the board of
directors of OAL during the term of the Debenture and so long as such has not
been repaid or converted.

5.       RH and RL shall enter into management agreements with OAL for a term of
not less than the Debenture term, on terms no better as to salary than that set
forth below, and shall be responsible for supervising the implementation and
completion of the Production Plan.

6.       OAL warrants that it has an option on 50% of the Project and the
property thereof pursuant to the Option Agreement and extension agreement
between OAL and Pierre Martre and, to the best of OAL's informed knowledge,
Pierre Martre has contracted 100% of the mining rights of the property and
Project and neither the property nor the Project are subject to any
encumbrances, liabilities, claims, threats to the title or integrity of the
property or the Project, nor does any party have any claim or challenge to title
or ownership of the Project or property. OAL further warrants that OAL is free
and clear of all liens, encumbrances, or any claims by any parties (other than
normal course payables), there are no rights or contracts for the issue of
securities except as set forth herein, OAL is not threatened with insolvency
proceedings, the Option Agreement is in good standing and no other party has any
rights or interests therein, and the Debenture funds hereof shall be adequate
for the expenditure and maintenance needs of the Option Agreement and for the
general operations and payables of AOL during at least phase one of the
development program of the Project.

7.       During the term of the Debenture and the below Option, Azco shall have
the right to provide, or provide for, all future financings of OAL and its
interest in the Project on competitive terms. Azco shall have a first right of
refusal in respect to any bona fide financing offers, earn-in options, purchase
offers, joint venture offers, bank financings, equity offers, or any other such
matter of OAL. No alteration in the capital or debt structure of OAL nor any
alteration of the Project or its status or its financing may be made except by
consultation with and approval of Azco, not to be unreasonably with held.

                  shares;

           (Seville and Minera Cortez being hereinafter collectively referred to
           as "Minera" as the context so requires); and


           (Azco and Minera being hereinafter singularly also referred to as a
           "Party" and collectively referred to as the "Parties" as the context
           so requires).


           WHEREAS IN CONSIDERATION of the mutual covenants contained in, and
the mutual benefits to be derived from, this Agreement, and including, without
limiting the generality of the foregoing, the subscription by Azco for 200,000
common shares of Mineral Cortez at a subscription price of $0.25 per common
share, the Parties hereto agree as follows:


                                    ARTICLE I

                   RIGHT OF FIRST REFUSAL - PROPERTY INTERESTS


1.1        RESTRICTION AND ASSIGNMENT RESPECTING PROPERTY INTERESTS. During the
subsistence of this Agreement, which shall be for a period of five years from
the above-referenced Effective Date of this Agreement (the "Option Period"),
Minera may not joint venture, option, sell, transfer or otherwise dispose of all
or any part of its present or hereinafter acquired interest in and to any
resource property interest (each being a "Property Interest") except in
accordance with the terms of this Agreement; provided, however, that Minera may
at any time at its sole discretion and without the prior approval of Azco assign
and transfer a Property Interest to any of its wholly owned subsidiaries, if
any, subject at all times to the requirement that any such subsidiary remain
wholly owned by Minera failing which any such interest must be immediately
transferred back to Minera; and provided further that any transfer of all or any
part of Minera's Property Interests or interests under this Agreement to its
wholly owned subsidiary shall be accompanied by the written agreement of any
such subsidiary to assume the obligations of Minera hereunder and to be bound by
the terms and conditions hereof.


1.2        RIGHT OF FIRST REFUSAL ON ANY OFFERED PROPERTY INTERESTS. Minera
hereby grants to Azco a 60 calendar day right of first refusal during the Option
Period to acquire all, but not less than all, of any Property Interest which
Minera desires to either joint venture, option or dispose of in any manner
during the Option Period (each being an "Offered Property Interest").


1.3        BONA FIDE OFFER. If Minera receives a bona fide offer (an "Offer") to
either joint venture, option or sell any Offered Property Interest, then Minera
shall forthwith offer the Offered Property Interest to Azco. The offer to Azco
shall be on terms and conditions substantially identical to, and of pro rata
equivalent dollar value as, those contained in the Offer either to or from the
third party.




                     -- Right of First Refusal Agreement --
                             -- Azco Mining Inc. --




<PAGE>   4
                                      -3-



1.4        ELECTION. Azco shall be entitled to elect, by notice in writing (the
"Notice") to Minera within 60 calendar days from the date of receipt by Azco of
the Offer, to accept the Offered Property Interest on terms and conditions
substantially identical to those contained in the Offer either to or from the
third party (collectively, the "Terms and Conditions"). If Azco fails to provide
the Notice within the time required, Azco shall be deemed to have declined to
exercise its right of first refusal in connection with that particular Offer.


1.5        CONSIDERATION. Subject to Article "III" hereinbelow, in the event
that Azco elects, pursuant to section "1.4" hereinabove, to accept an Offered
Property Interest then, notwithstanding the remaining Terms and Conditions, and
in order that Azco may accept the Offered Property Interest on terms
substantially identical with the proposed consideration terms under the original
Offer, Azco will be entitled to match the proposed consideration terms under any
such Offer by way of the equivalent combination of both issuing shares of Azco
(collectively, the "Shares") and paying cash consideration (the "Cash
Consideration") to Minera such that the value of any such Shares and/or Cash
Consideration, as the case may be, will be equivalent in value to the proposed
consideration terms under the Offer and in the substantially identical relative
share/cash proportions. In this regard, and in order to more particularly
determine the value of any Shares to be provided by Azco for its acceptance of
an Offered Property Interest, Azco shall be entitled to utilize the previous
ten-day average closing price of Azco's common shares on The Toronto Stock
Exchange as at the date of any Notice as the appropriate per Share price forming
part of any such Share consideration. For greater certainty it is hereby
acknowledged and agreed that any proposed consideration under the terms of an
Offer which contemplates either cash consideration and/or work commitment
expenditures or the like must be matched by Azco in the Terms and Conditions of
its Notice.


1.6        NOT EXERCISED. If Azco does not exercise its right to accept an
Offered Property Interest as aforesaid, Minera may, for a period of 180 calendar
days following the last date upon which Azco could have made the election
pursuant to section "1.4" hereinabove, dispose of the Offered Property Interest
but only on terms and conditions substantially identical to those as contained
in the Offer for that Offered Property Interest.


1.7        TERMINATION OF RIGHT OF FIRST REFUSAL. Except with respect to the
specified Offered Property Interest, the right of first refusal to acquire up to
100% of any Offered Property Interest will not terminate if, on receipt of any
Offer from Minera under this section, Azco fails to exercise the right.


1.8        EXCLUSIONS TO RIGHT OF FIRST REFUSAL. The right of first refusal
shall not apply to any sales or transfers of Property Interests from Seville to
Minera Cortez. In addition, it shall be subordinated to any such right granted
by Minera Cortez in any joint venture, option or property purchase to an
optionor or vendor of any Property Interests acquired by Mineral Cortez
subsequent to the Effective Date hereof.

                                   ARTICLE II

              RIGHT OF FIRST REFUSAL - FINANCINGS FOR MINERA CORTEZ


2.1        NOTIFICATION. Minera Cortez will notify Azco of the terms of any
further private and/or public equity or debt financing that it requires or
proposes to obtain during the Option Period (each a "Financing") and Azco will
have the right of first refusal to provide up to 100% of any such Financing on
terms and timing substantially identical as any third party is prepared to
provide.


2.2        EXERCISE OF RIGHT. This right of first refusal must be exercised by
Azco within 7 calendar days following its receipt of the notice from Mineral
Cortez offering terms of Financing, or advising that it is prepared to accept a
third party offer of Financing, by notifying Minera Cortez that they will
provide up to 100% of such Financing on terms substantially identical to those
contained in the notice.


2.3        FAILURE TO GIVE NOTICE. If Azco fails to give notice within the 7
calendar days that it will provide up to 100% of such Financing upon the terms
set out in the notice, Minera Cortez will then be free for 180 calendar days to
make other arrangements to obtain financing from another source on substantially
identical terms.


2.4        TERMINATION OF RIGHT OF FIRST REFUSAL. The right of first refusal to
provide Financing will not terminate if, generally, on receipt of any notice
from Minera Cortez under this section, Azco fails to exercise the right for that
Financing.


2.5        EXCLUSIONS TO RIGHT OF FIRST REFUSAL. For greater certainty the right
of first refusal to provide Financing hereunder shall not apply to any
securities issued by Minera Cortez for incentive stock options, to vendors or
optionors for properties, pursuant to any amalgamation or reorganization or
pursuant to its initial public offering of securities (unless Minera Cortez will
thereupon have adequate share distribution for listing). In addition, the right
of first refusal to provide Financing shall not apply to Seville.


                                   ARTICLE III

                                   ARBITRATION


3.1        MATTERS FOR ARBITRATION. Notwithstanding section "1.5" hereinabove,
the Parties hereto agree that all questions or matters in dispute with respect
to this Agreement shall be submitted to binding arbitration pursuant to the
terms hereof.


3.2        NOTICE AND NEGOTIATION. It shall be a condition precedent to the
right of any Party to submit any matter to arbitration pursuant to the
provisions hereof that such

                                      -5-


Party intending to refer any matter to arbitration shall have given to the other
Party, not less than 10 calendar days' prior written notice of its intention to
do so, together with reasonable particulars of the matter in dispute, and that
such complaining Party shall have invited the noticed Party at least once to
negotiate the dispute. On the expiration of such 10 calendar days the Party who
gave such notice may proceed to refer the dispute to arbitration as provided for
in section "3.3" hereinbelow.


3.3        APPOINTMENTS AND PROCEDURE. After the 10 calendar day period set
forth in section "3.2" hereinabove a Party desiring arbitration shall appoint
one arbitrator with a statement of credentials and shall notify the noticed
Party of such appointment, and the noticed Party shall, within 10 calendar days
after receiving such notice, agree that such first arbitrator shall be the only
arbitrator or shall appoint a second arbitrator and give notice of the same. The
two arbitrators so named, before proceeding to act, shall, within 10 calendar
days of the appointment of the last appointed arbitrator, agree on the
appointment of a third arbitrator to act with them, and such three arbitrators
shall select a chairman from themselves. If the noticed Party shall fail to
appoint and give notice of an arbitrator within 10 calendar days after receiving
notice of the appointment of the first arbitrator, then the first arbitrator
shall act as a single arbitrator, and if the two arbitrators appointed by the
Parties shall be unable to agree on the appointment of a third, then the third
arbitrator shall be appointed under the provisions (the "Rules") of the
Commercial Arbitration Act (British Columbia) or, failing that, by a judge of
the Supreme Court of the Province of British Columbia on the motion of any Party
to the dispute. Except as specifically otherwise provided in this section, the
arbitration herein provided for shall be conducted in accordance with such
Rules. Where there is an insufficiency in this Article or the Rules then the
arbitrators shall make reference to the provisions of the procedures and
practices of the British Columbia International Commercial Arbitration Centre
(Domestic Arbitration) and, if there is further insufficiency, and otherwise in
interpretation and rulings regarding this Article or the Rules and regarding the
matters of dispute, the arbitrators shall be the masters of procedure, evidence,
rules of order and the process of law and judgment. Where this Agreement, the
constating documents of either Party, other documents relevant to the Parties or
the law does not provide for or address any material matter in dispute, then the
arbitrator(s) shall have reference to the customary practice of the industry
and, if the Parties do not call expert testimony, the arbitrator(s) may, but is
not obliged to, call its own determined expert testimony at the cost of the
Parties. The arbitrators, or in the case where only one arbitrator is appointed,
the single arbitrator, shall fix a time and place in accordance with agreement
of the Parties or the Rules and shall establish the calendar and procedure for
the purpose of hearing the evidence and representations of the Parties. When
Azco is not a party to the arbitration the Parties and the arbitrator(s) shall
copy Azco with all correspondence and submissions to or from the arbitrator(s)
(omission to do so shall not invalidate the proceedings) unless the
arbitrator(s) rules that any communication is privileged, or any rulings or
awards. Azco shall have the right to intervene in the arbitration and have
standing to make representations on such terms as to costs as the arbitrator(s)
may determine. Any arbitration shall be transcribed, unless the Parties waive
such, and the proceedings and hearings and decisions shall be confidential and
in closed hearings unless the Parties waive such, partly or wholly or as may be
necessary for any execution of an arbitration award. After hearing any evidence
and representations that the Parties may submit, the single arbitrator, or the
arbitrators, as the case may be, shall make an award and reduce the same to
writing, and deliver one copy thereof to each of the Parties. The expense of the
arbitration shall be paid as specified in the award but, failing specification,
each Party

shall bear its own costs and the losing party shall bear the cost of the
arbitrator(s) and the arbitration facilities.


3.4        AWARD. The Parties agree that the award of a majority of the
arbitrators, or in the case of a single arbitrator, of such arbitrator, shall be
final, binding and enforceable upon each of them and shall not be appealable
except for manifest error of law.


                                   ARTICLE IV

final).

in this Agreement, if any, are inserted for convenience of reference only and

to bear the execution date as set forth on the front page of this Agreement.


4.10       NO PARTNERSHIP OR AGENCY. The Parties have not created a partnership
and nothing contained in this Agreement shall in any manner whatsoever
constitute any Party the partner, agent or legal representative of any other
Party, nor create any fiduciary relationship between them for any purpose
whatsoever. No Party shall have any authority to act for, or to assume any
obligations or responsibility on behalf of, any other party except as may be,
from time to time, agreed upon in writing between the Parties or as otherwise

           required Expenditures on the Property and made the required payments
           in accordance with article 3 above, it shall be deemed to have
           exercised its option with respect to acquiring the AZCO Interest
           (unless revoked in the time set forth in section 3.2) and AZCO shall
           have thereby, without any further act, acquired such interest, and
           shall be therein vested, and CORTEZ shall transfer such interest on
           the relevant public title records and with the relevant agencies or
           the grantors of the Option Agreement upon AZCO's request.


5.2        JOINT VENTURE. Upon the acquisition by AZCO of the AZCO Interest, the
           proportionate interests of CORTEZ and AZCO shall be governed by a
           joint venture agreement or common joint venture company, whichever
           counsel advises is most appropriate under Mexican law and practice
           (both corporate and tax) and whose interests shall be proportionately
           reflected in the agreement or entity. The parties shall form such
           agreement or entity in accordance with British Columbia practice and
           law, as necessarily modified for Mexican law, and such shall be
           negotiated in good faith and, further, shall be negotiated at the
           requirement of either party. If a joint venture agreement is
           recommended by counsel, the basic form employed shall be that of the
           Rocky Mountain Mineral Law Foundation Joint Venture Form 5. If a
           joint venture company is recommended then the shareholder agreement
           shall be that basic form commonly referenced in material of the CLE
           of the law society of British Columbia. Whether corporate entity or
           joint venture agreement, the following shall be encompassed in the
           shareholder or joint venture agreement:


           (a)        required representation of each party (except where
                      diluted to a royalty interest only) on the board and
                      management committee with votes proportional to interest
                      ownership;


           (b)        all assets of and interests in the Property and activities
                      therein to be held by the entity, if possible, otherwise
                      by a mutually controlled entity or trust;


           (c)        financing obligations proportional to each parties
                      interest;


           (d)        dilution in the event of non-participation based upon a
                      deemed valuation of $100,000 per 1% interest, and a Party
                      converting to a 2% net smelter return interest if reduced
                      to an interest less than 10%;

           (e)        provisions for notice of, remedy for, and consequences of
                      failure to perform party obligations;


           (f)        a right of first refusal on any intended dispositions;


           (g)        standard terms and definitions shall be carried over from
                      this Agreement where the Parties cannot otherwise agree;
                      and


           (h)        unless otherwise agreed, the party with the largest
                      interest being operator but in the event of an equality
                      the operator shall be AZCO.

                                    ARTICLE 6

               RIGHT OF FIRST REFUSAL, ASSIGNMENT, AND ABANDONMENT


6.1        PARTIES' RIGHT OF FIRST REFUSAL. Each party hereby grants unto the
           other a right of first refusal to acquire the other's interest, or a
           portion thereof, in the Property (direct or indirect) in the event of
           any intended disposition of any interest from the date of execution
           of this Agreement. In the event a party chooses to assign or
           otherwise dispose of its interest, or a portion thereof, it shall
           forthwith notify the other, in writing, of the terms and conditions
           under which it is willing to sell its interest, which terms and
           conditions shall be the same terms and conditions as those contained
           in the intended offer to the third party. The receiving party shall
           be entitled to elect, by written notice to the other within 60 days
           from the date of receipt of the Notice, to acquire the interest on
           the terms and conditions provided for in the notice. If the receiving
           party does not exercise its right to acquire the offered interest,
           the disposing party may, for a period of 120 days following the last
           date upon which the other party could have made election, dispose of
           its interest, but only on the same terms and conditions as set forth
           in the notice. No disposition shall be effective until the transferee
           has executed the prevailing agreements to which the Property is
           subject, including this Agreement and any subsequent joint venture or
           shareholder's agreement. Notwithstanding the forgoing, AZCO may
           assign to a nominee or affiliate, without triggering a right of first
           refusal, its rights herein or in the AZCO Interest for the purpose of
           finance, for its organizational purposes, or for purpose of
           compliance with Mexican law to hold a Property interest or for the
           purpose of effecting a public floatation of its interests herein,
           subject to AZCO maintaining a controlling interest (at least
           initially for a going public process).


6.2        ABANDONMENT. In the event that any party hereto shall voluntarily
           elect to abandon any part or all of the Property (this shall not
           apply to abandonment required by law), or its interest therein, or
           its interest in this Agreement, then it shall give not less than
           thirty (30) days notice to the other party of such intent and of the
           nature and encumbrances and obligations of such interest and, upon
           the other party's election to receive such interest conveyed within
           such period, shall assign and quit-claim such interest to such other
           party for consideration of one ($1.00) dollar and the assumption of
           all disclosed liabilities and obligations thereof. A party's rights
           and obligations shall be calculated and accrued to the day the
           abandonment becomes effective in accordance with the notice issued in
           accordance with this clause.


6.3        PARTICIPATION OF MAJOR. Notwithstanding section 6.1 hereof, AZCO may
           assign any portion of its interest to a major mining company at any
           time.

                                    ARTICLE 7

                 REGISTRATION AND TRANSFER OF PROPERTY INTERESTS


7.1        REGISTRATION OF PROPERTY INTERESTS. The parties shall execute and
           deliver such additional documentation as legal counsel for the
           parties determines is necessary in order to duly register and record
           in the appropriate registration and recording offices notice that
           CORTEZ's Interest is subject to and bound by the terms of this
           Agreement.


7.2        TRANSFER OF PROPERTY INTERESTS. Upon earning of the AZCO Interest
           CORTEZ shall execute and deliver to AZCO such additional
           documentation as legal counsel for AZCO determines is necessary in
           order to duly register and record in the appropriate registration and
           recording offices a transfer of title in and to the Property. AZCO
           may, at its election and at any time, require that CORTEZ deposit in
           escrow the appropriate title transfer documents as AZCO's counsel may
           suggest.



                                    ARTICLE 8

                                 RIGHT OF ENTRY


8.1        RIGHT OF ENTRY. While this Option is in effect and when any part of
           the Option is exercised or until the Option is terminated in
           accordance with the terms of this Agreement without AZCO earning an
           interest, AZCO, its servants and agents shall have the right to:


           (a)        enter in, under or upon the Property and conduct
                      Exploration and Development and Mining Work;

           (b)        exclusive and quiet possession of the Property;

           (c)        bring upon the Property and to erect thereon such
                      facilities as it may consider advisable; and

           (d)        remove from the Property ore or Product for the purpose of
                      bulk sampling, pilot plant or test operations.



                                    ARTICLE 9

                                    OPERATOR


9.1        OPERATOR. AZCO, or its duly authorized nominee, assignee, or
           contractor, will act as the Operator of the Property, under the
           authority of the Management Committee, during the currency of this
           Agreement.

                      reasonable times for the purpose of inspecting work being
                      done thereon but at their own risk and expense;

           (b)        employ and engage such employees, agents and independent
                      contractors as it may consider necessary or advisable to
                      carry out its duties and obligations hereunder and in this
                      connection to delegate any of its powers and rights to
                      perform its duties and obligations hereunder; and

           (c)        to engage Expenditures as the Operator may determine in
                      its sole discretion to conduct, provided it shall act
                      under the supervision and guidance of the Management
                      Committee, in accordance with development programs

                      provisions of Clause 9.3 hereof.


9.3        DUTIES AND OBLIGATIONS. After execution of this Agreement, the

                      prudent and workmanlike manner, and in compliance with all
                      applicable laws, rules, orders and regulations;

                      in progress within 14 days of the end of the relevant
                      period;

           (c)        subject to the terms and conditions of this Agreement, to

                                   ARTICLE 10

                              MANAGEMENT COMMITTEE


10.1       THE MANAGEMENT COMMITTEE. The Management Committee shall consist of
           four individuals, two each of whom shall be designated by each of
           AZCO and CORTEZ. Either party may appoint new representatives at any
           time and representatives may delegate proxies and alternates at any
           time. The Management Committee shall be responsible for approving
           plans and budgets for Exploration and Development and Mining Work and
           Expenditures and for determining the general policies and direction
           to be used in the conduct of operations hereunder. The Management
           Committee shall meet at least once annually and otherwise on thirty
           (30) days' notice given by a Party. All notices of Management
           Committee meetings must specify, or include an agenda which
           specifies, the matters to be discussed at such meetings. A Party's
           representatives may in any manner and at any time waive a notice of a
           meeting of the Management Committee and attendance of a Party's
           representative at a meeting of the Management Committee is a waiver
           of notice of the meeting, except where a Party's representative
           attends a meeting for the express purpose of objecting to the
           transaction of any business on the grounds that the meeting is not
           properly called. Decisions of the Management Committee shall be made
           by majority vote at a duly called and constituted meeting of the
           Management Committee. Each Party shall be entitled to two votes on
           the committee during the Option period. In the event of any
           deadlocked vote at a meeting of the Management Committee, AZCO,
           during the Option (as the provider of finance) and otherwise while
           Operator, shall have the casting vote. It is the intention of the
           Parties that decisions of the Management Committee shall be made in
           accordance with sound business and commercial judgment.


10.2       QUORUM. A quorum for a Management Committee meeting shall be present
           and such meeting shall be duly constituted when proper notice has
           been given or waived and 51% of the available votes are represented
           and a voting representative of each Party is present in person or by
           proxy at such meeting. In the event a quorum is not present at such
           meeting, the Operator may immediately give notice of a second meeting
           to be held within 10 days thereafter, at which meeting a quorum shall
           be deemed to be present and such meeting shall be duly constituted if
           50% of the available votes are represented regardless of whether
           voting representatives of each Party are present. All decisions taken
           by the Management Committee shall be binding upon the Parties (except
           for matters requiring


<PAGE>   13
                                      -13-



           unanimity) and any decision which may be made at a meeting of the
           Management Committee may also be made by an agreement or resolution
           in writing signed by all of the Parties' representatives who would be
           entitled to vote on that decision at a meeting of the Management
           Committee. The Operator shall keep minutes of the Management
           Committee meetings which, when delivered to the representatives of
           all Parties, shall constitute evidence of proceedings taken and
           decisions made at such meeting. All meetings of the Management
           Committee, unless otherwise agreed to by the Parties, shall be held
           at the location selected by the Operator. If all of the
           representatives of the Parties entitled to vote at an Management
           Committee meeting consent, a meeting of the Management Committee may
           be held by means of such telephone, electronic or other
           communications facilities as permit all persons participating in the
           meeting to communicate with each other simultaneously and
           instantaneously, and a Party's representative participating in such
           meeting by such means is deemed for the purpose of this Agreement to
           be present at that meeting. Any consent by a Party's representative
           to such meetings shall be effective whether given before or after the
           meeting to which it relates and may be given with respect to all
           meetings of the Management Committee.


10.3       CONTINUANCE OF MANAGEMENT COMMITTEE AND AGREEMENT. Upon AZCO having
           earned an interest and this Agreement requiring that the successor
           agreement be engaged, this Agreement and the Management Committee and
           the Operator shall continue until replaced or continued pursuant to
           the successor structure agreement (whether joint venture or corporate
           entity). This Agreement shall continue to govern and the Management
           Committee and the Operator shall govern the Property in the same
           manner as in the preceding sections until replaced by subsequent
           agreement. If a party fails to contribute to costs during such an
           interregnum, the other party may elect to pay the cost and the
           non-paying party shall, at the election of the paying party, be
           diluted at the rate of section 5.2(d). Notwithstanding the forgoing,
           a Party may instead determine to carry another Party's costs as a
           demand loan at an interest rate of 12% per annum calculated and
           compounded monthly, not in arrears, and such Party carrying the costs
           may elect to seek recovery or to dilute at any time.



                                   ARTICLE 11

                             DEFAULT AND TERMINATION


11.1       DEFAULT. The Parties hereto agree that if a party is in default with
           respect to any of the provisions of this Agreement, the
           non-defaulting party shall give written notice to the defaulting
           party, and specifying the nature of the default, and within thirty
           (30) days (or such shorter period if required by imperatives of law)
           after its receipt of such notice, the defaulting party shall either:


           (a)        cure such default, or commence proceedings to cure such
                      default and prosecute the same to completion without undue
                      delay; or

           (b)        give the non-defaulting party notice that it denies that
                      such default has occurred and that it is submitting the
                      question to arbitration under the provisions of this
                      Agreement, whereupon a party shall not be considered in
                      default until an arbitration so rules.

11.2       FAILURE TO CURE DEFAULT. If:


           (a)        a default is not cured or the defaulting party does not
                      commence and diligently proceed to cure the default within
                      the required period; or

           (b)        arbitration is not sought; or

           (c)        the defaulting party is found in arbitration proceedings
                      to be in default, and fails to cure it or commence curing
                      it, and proceed without delay within thirty (30) days
                      after the rendering of the arbitration award,

           then the non-defaulting party may, by written notice given while the
           default continues, terminate this Agreement and seek such specific
           performance and damages as it may determine. The defaulting party
           shall comply with the provisions of section 4.2, mutatis mutandis, in
           respect to any declaration by the non-defaulting party resulting in
           withdrawal of a party from the Property.

                              AND VENTURE AGREEMENT


           THIS AGREEMENT is dated and made for reference effective (the
"Effective Date") as of the 18th day of November, 1997.


BETWEEN:

           AZCO MINING INC, and its appointed affiliates, subsidiaries, and
           assigns, with its address for delivery and service at Suite 1250 -
           999 West Hastings Street, Vancouver, B.C. V6C 2W2

           (hereinafter referred to as "Azco");

                                                               OF THE FIRST PART

AND:

           LION MINING CORPORATION LIMITED and its appointed affiliates,
           subsidiaries, and assigns, of 7 - 8 Kendrick Mews, London, England
           SW7 3HG

           (hereinafter referred to as "Lion");

                                                              OF THE SECOND PART

           (Azco and Lion being hereinafter singularly also referred to as a
           "Party" and collectively referred to as the "Parties" as the context
           so requires).


           WHEREAS:


A.         Azco and Lion have a mutuality of interest in the field of mining
exploration and finance;

B.         In 1996 the Parties commenced business relations in regard to mining
business in Africa and elsewhere with the intention that such would be
memorialized in a future contract of co-venture when the experiences of the
first endeavors had been absorbed and could direct the structure of a formal
agreement;

C.         Through the introduction of Lion, Azco and Lion Mining Finance
Limited (an affiliate of Lion and which has assigned its interests therein to
Lion) entered into a Memorandum of Agreement (hereinafter called the "Mali
Agreement") dated effective May 9, 1996 and to which Mali Agreement, West
African Gold and Exploration Ltd. and Eagle River International Limited
(hereinafter called "Eagle") are also parties as the vendors of certain mineral
interests;

D.         By the nature of the Mali Agreement and the Parties' relative
relations with Eagle, Azco contractually agreed to advance the initial
contributions prior to a roll-over of the proposed project into a publicly
listed self-funding entity and, in compliance therewith, Azco has advanced loans
to Eagle and its subsidiaries in excess of US $4,000,000 towards the Mali
Agreement;


<PAGE>   2
                                      -2-



E.         By the terms of the Mali Agreement, Azco was to be repaid all of its
loan advances (which have been advanced to Eagle and its subsidiaries and which
parties have issued security notes for the same) if certain preconditions and
warranties were not met. It has transpired that Azco and Lion suffered
misrepresentation by Eagle with the result that those pre-conditions have not
been achieved and cannot be achieved (including a warranty that the subject
properties thereof would have a value of no less than US $3,125,000), default
has been declared to Eagle, and Azco has been required to write-down its
advances to a nominal position;

F.         Azco and Lion have determined to cooperate to pursue any available
remedies in regard to Eagle and to profit from the experience by employing the
same in the formalizing of the issues of a Venture agreement encapsulated
herein;


           NOW THEREFORE THIS AGREEMENT WITNESSETH THAT in consideration of the
within covenants and other consideration, the receipt and sufficiency of which
is hereby acknowledged, THE PARTIES HERETO MUTUALLY COVENANT AND AGREE AS
FOLLOWS:


1.         VENTURE STRUCTURE. The Parties hereby create and formally recognize a
grant to Azco of a right of first refusal and of a venture between Azco and
Lion, in the event of exercise of such right of first refusal at any time,
having the following principle characteristics:

           (a) the purpose of this Venture (the "Venture") is, employing
           Opportunities (as below defined) located by Lion and accepted for the
           Venture by the Technical Committee (defined below), to pursue the
           mutual profitable exploitation of the Opportunities on the terms of
           this Agreement;

           (b) the name of the Venture shall be the "Kingfisher Venture";

           (c) the Venture shall be operated by a management and technical
           committee (the "Technical Committee") composed of no less than one
           representative of each of Azco and Lion. Azco's representative(s)
           shall collectively represent six votes and Lion's representative(s)
           shall collectively represent four votes and the cost of such
           representatives shall be borne by each Party solely. No meeting of
           the Technical Committee shall be conducted unless a majority of
           voting interests are present, no less than 10 days notice has been
           given (or waived) and at least one member of each of Lion and Azco
           are present unless, as to this latter requirement, at least one
           adjournment has occurred and 5 days notice of recall has been given.
           Meetings of the Technical Committee may be conducted in person or by
           telephone conference or by consent resolution. Notwithstanding the
           forgoing, the Technical Committee shall not impose any material
           financial burdens on the Venture and the Parties unless specific
           notice has been given prior to any meeting and if any Party shall be
           unable to attend through its representative at any such meeting, it
           shall have the right to require a further meeting to re-consider any
           part which it finds objectionable. The Technical Committee shall
           maintain minutes of its meetings and deliberations and each Party
           shall be entitled to a copy of such minutes;

           (d) this Agreement shall constitute the fundamental constitution of
           the Venture governing the relations of the Parties, in a manner
           similar to corporate articles under British Columbia corporate
           practice and law. Matters not addressed by this Agreement or which
           constitute specific and day-to-day operating and management policies
           shall be determined by resolution of the Technical Committee with
           power and effect equal to corporate board of directors resolutions;

                                      -3-



           (e) the participating and contributory interests of Azco and Lion
           (subject to adjustment as to a specific project as elsewhere set
           forth in this Agreement) shall be sixty (60%) percent to Azco and
           forty (40%) percent to Lion (such interests are referred to as
           "Participating Interests").

           (f) profits of the Venture may be distributed at such times as the
           Technical Committee may determine. Profits shall be calculated as net
           of payment of all debts and costs of the Venture, payment to the
           Parties of costs carried on behalf of the Venture, reservation of
           working capital considered prudent by the Technical Committee, and
           after payment of any outstanding Negative Balance (as below defined).
           The Technical Committee shall determine the accounting treatment and
           policy of the Venture finances. The Technical Committee shall not be
           required to distribute or record mineral interests or any
           undistributed asset, in the Parties' individual names but may hold
           the same in the name of the Venture or a controlled company. Any
           Party may require distribution of cash or shares constituting
           distributable profit on a quarterly basis;

           (g) Azco and Lion shall contribute the following rights, goods,
           services, and capital as their contribution to the Venture:

                      (i) Lion shall diligently seek and make available, from
                      opportunities which come to its attention, are discovered
                      by it or are brought to it, mineral opportunities (the
                      "Opportunity") within the criteria established by the
                      Technical Committee and shall bear the cost of such search
                      and initial analysis. Upon Azco exercising its right of
                      first refusal by its representatives on the Technical
                      Committee determining to proceed to do due diligence and
                      to complete a contract of acquisition of an Opportunity
                      Lion shall be refunded by the Venture or Azco (in the
                      initial stage as to the latter) that proportion of the
                      carried cost of such Opportunity equal to its full cost
                      less its Participating Interest share. At the discretion
                      of the Technical Committee, where Lion has incurred costs
                      outside of its normal business endeavors in seeking
                      Opportunities and the Technical Committee has not
                      determined to proceed with certain of the same and Lion
                      has not been able to recover its costs by disposition of
                      such to third parties, then the Technical Committee may
                      determine that Lion shall recover some or all of such
                      costs from the Venture;

                      (ii) Lion grants unto Azco the exclusive first right to
                      acquire, pursue, and develop an Opportunity on the terms
                      of this Venture, except for those projects, Ventures, or
                      other agreements that are disclosed in Schedule "B" hereto
                      to which Lion has prior commitment;

                      (iii) Azco and Lion shall make available to the Venture
                      their expertise, staff, and other available and pertinent
                      resources at cost plus a 15% management fee or at their
                      `best customer' price, or at their opportunity cost of
                      resources, as accepted by the Technical Committee, to be
                      carried or paid by the Venture out of proceeds of
                      Opportunities and out of retained earnings, as the same
                      may be reserved by the Technical Committee from the
                      Parties' share of proceeds of the Venture;

                      (iv) upon the Technical Committee determining to pursue an
                      Opportunity for the Venture, Azco shall fund, or provide
                      funding for, the initial acquisition or contract securing
                      costs (the "Acquisition Cost") of an Opportunity, which
                      shall be repaid first (including all accumulated
                      unrefunded Acquisition Costs of any preceding
                      Opportunities) out of proceeds of disposition or
                      production only. However it is understood by the Parties
                      that where Acquisition Costs or other Opportunity costs
                      are to be rolled-over into a private or public finance
                      vehicle that the Parties will mutually and independently
                      use best reasonable endeavors to seek and acquire the
                      required finance to


<PAGE>   4
                                      -4-



                      service such costs of an Opportunity and to avoid Azco
                      being required to advance the Acquisition Cost, where
                      possible; and

                      (v) thereafter, Azco and Lion shall provide capital and
                      other required resources as to any Opportunity in
                      proportion to their Participating Interests;

           (h) as part of the determination of the Technical Committee regarding
           an Opportunity it shall apply financial analysis and management
           planning to any Opportunity to determine the most advantageous and
           beneficial means of adding value to any Opportunity including,
           without restricting the determination of the Technical Committee, to
           develop the Opportunity privately (with or without third party
           participants) and to sell such at any time or to take such to
           production, or (shortly after acquisition or after private
           development) to assign the Opportunity to a public company (or take a
           private company public) and receive any combination of cash, shares,
           or debt for the same. As a general principle, a roll-over to a
           separate finance vehicle and the employment of independent financial
           resources (whether private or public) shall be the preferred option;

           (i) Lion shall provide a best reasonable efforts initial assessment
           of Opportunities sufficient to allow a reasoned judgment on the
           merits of an Opportunity and shall provide the Technical Committee
           with all material reasonably available to it and reasonably
           accessible for analysis. The Parties and the Technical Committee
           shall sign all such confidentiality agreements as are reasonably
           required by the Opportunity owners. The Technical Committee shall
           employ reasonable best efforts to make an initial go/no-go decision
           on further efforts and due diligence regarding the Opportunity. In
           the event that the Technical Committee determines not to proceed then
           Lion shall be at full liberty to seek its sole profit from such
           Opportunity thereafter without further reference to the Venture. In
           the event that the Technical Committee determines to proceed with an
           Opportunity then Lion shall employ reasonable best efforts to permit
           the Technical Committee to negotiate the terms of the agreement with
           the Opportunity owner and the Technical Committee shall employ
           reasonable best efforts to finalize such agreement and due diligence
           as soon as possible;

           (j) in the event that in regard to any Opportunity a Party cannot
           fund its required contributions in accordance with its Participating
           Interest and the development plan of the Technical Committee then it
           shall be subject to dilution in regard to its Participating Interest
           in such Opportunity in accordance with a formula agreed by the
           Parties. In the event that the Parties cannot agree on a dilution
           formula then the formula shall be a reduction of one full Opportunity
           percentage point (one point out of the 100% aggregate all-Party
           points of the Opportunity) for each incidence of non-contribution
           calculated by the required contribution per point on a quarterly
           basis which the non-contributing Party has not funded (and such
           diluted interest transferring at the end of each quarter with
           concomitant alteration to the Participating Interest percentage of
           each Party). However, on the first anniversary date of the unfunded
           contribution the non-contributing Party shall have a one-time right
           to buy-back all the diluted interest of such quarter in reference by
           paying the funding Party double the expenditures incurred in respect
           to the diluted interests. In the event that the Party being diluted
           seeks to assign some or all of its interest or to seek a funding
           partner for its costs then the other Party shall have first right to
           provide such funding upon the terms intended or contracted to be
           offered (open for 30 days for determination after receipt of all
           pertinent details of the offer) and, in the event that it elects to
           provide the funding, then there shall be no buy-back right in respect
           to the consideration provided for such funding. In the circumstance
           in which an Opportunity remains private strictly within the Venture
           as a development of the Venture, a Party shall not be diluted to less
           than a ten (10%) percent working interest prior to commercial
           production but shall be carried in the form of a loan which shall be
           repaid out of sale of the Opportunity or from two-thirds (2/3rds) of
           the diluted Party's share of revenue of such Opportunity. All such
           carried loans shall bear interest at the carrying Party's cost of
           money with its principal bank,

                                      -5-



           fixed annually, plus three (3%) percent calculated and compounded
           annually at the time of interest fixing;

           (k) the Parties shall not assign their Participating Interests in
           this Venture for a period of two years from the date hereof (except
           to controlled subsidiaries or affiliates) and thereafter shall offer
           the other Party a right of first refusal exercisable for a period of
           60 days following delivery of all pertinent details of the offer. If
           the receiving Party does not exercise the right of first refusal then
           the selling Party shall be free to dispose of the offered interest on
           the same terms for a period of 180 days thereafter. Any sale of a
           part or all of a Participating Interest shall not be effective until
           the purchaser has executed a copy of this Agreement or any successor
           agreement;

           (l) in the event of any dispute between the Parties the Parties shall
           employ best efforts to settle the same by good faith negotiations for
           a period of not less than 30 days after written notice of a dispute
           and thereafter shall arbitrate the same before an agreed arbitrator
           in accordance with the Commercial Arbitration Act of British Columbia
           and any arbitration decision shall be final; and

           (m) the term of this Venture shall be the longer of three (3) years
           or the payout of the Negative Balance plus six months, regardless,
           expiring on December 31, 2010, renewable by mutual agreement of Azco
           and Lion. Notwithstanding the termination of this Venture, in
           circumstances in which one or more Opportunities are in progress then
           the terms of this Agreement shall continue only in respect to such
           Opportunity(ies) only to the extent required to govern the Parties'
           rights and obligations in respect to such Opportunity(ies).

2.         COMMENCEMENT ISSUES. This Venture shall be deemed to commence
effective the Effective Date with the following commencement issues and
conditions:

           (a) Lion shall declare all projects, opportunities, and corporate
           agreements which it has in effect on the Effective Date and which are
           thereby to be excluded from, or restrict the ambit of, the
           Opportunities of this Venture and are set forth in Schedule "B"
           hereto;

           (b) Azco shall be deemed to have a negative draw balance (the
           "Negative Balance") in the Venture relating to the first endeavor,
           being the Malian Agreement, equal to its total expenditures in regard
           to the Malian Agreement less all recoveries, including tax recoveries
           and fair value of equipment, all with a final valuation cut-off
           effective the Effective Date and accounted on or before March 1,
           1998, except if Azco realizes any recoveries (or debits) from Eagle
           or taxation after such date then there shall be a subsequent
           add-back; the Parties acknowledging that it is considered highly
           unlikely that any recoveries will be effected from Eagle (as it is in
           bankruptcy) and Azco shall be under no requirement to pursue any
           remedies. Lion agrees that it hereby assigns to Azco all its rights
           and interests in the Malian Agreement and agrees to cooperate fully
           with Azco in the pursuit of any remedies against Eagle and Azco
           agrees that any judicial remedies, and any costs borne by Lion in any
           requested assistance to Azco, shall be at Azco's sole expense. The
           Parties further agree that any results of Azco's endeavors, positive
           or negative, after the Effective Date to mitigate its damages
           (including any efforts to pursue and effect expenditures regarding
           any part of the properties of the Malian Agreement to create value)
           or to pursue its remedies shall solely accrue to Azco and shall be at
           its sole cost and risk and Lion shall not participate therein, nor be
           accountable for any part thereof, and shall be held harmless for any
           consequences flowing therefrom and arising from Azco's activities
           thereto and the Parties shall execute mutual releases. Lion shall be
           considered to have an equivalent $60,000 Negative Balance relating to
           the Malian Agreement;

           (c) Azco's and Lion's Negative Balance shall be reduced, pro rata,
           only from profits of the Venture, after all costs of the Venture, and
           shall be reduced by a preferential allocation of 60%


<PAGE>   6
                                      -6-



           of first profits available for distribution prior to any distribution
           being accounted for Participating Interests. The Parties further
           agree that, whenever reasonably possible without materially harming
           an Opportunity's prospects for financing, best efforts will be made
           to include in financing an allocation to retire the Negative
           Balances;

           (d) attached hereto as Schedule "A" are the initial selection
           criteria for Opportunities, which may be altered by the Technical
           Committee, as it so determines from time-to-time; and

           (e) attached hereto as Schedule "C" are the initial organizational
           principles for the Technical Committee, which may be changed by the
           Parties, as to appointees, and the Technical Committee, as to their
           organizational principles, at any time.

3.         GENERAL TERMS. The following general terms apply to the Venture and
the Parties' relations in respect thereto:

           (a) the Parties will support each other's good name and reputation
           and will employ good faith and reasonable best endeavors in the
           performance of this Agreement and their mutual endeavors;

           (b) the Parties will maintain all activities in respect hereto and in
           respect to each other and any Opportunities in confidence, except as
           required by any legal requirements to which a Party is subject;

           (c) when any benefits, such as shares, are distributed to Parties
           from the Venture the Parties shall be free to employ the same to
           their individual benefit thereafter;

           (d) this Agreement does not constitute a partnership nor in any
           manner shall the Parties hold themselves out as such;

           (e) this Agreement constitutes an enforceable agreement in principle
           but the Parties agree to negotiate a more detailed agreement in good
           faith at the requirement of any Party. Should a more detailed
           agreement not be effected then this Agreement shall continue to
           govern;

           (f) this Agreement shall be construed and enforced in accordance with
           British Columbia law;

           (g) all notices required hereunder shall be delivered to the Parties
           at the foregoing addresses, or such other addresses as subsequently
           advised in writing, and to the Technical Committee members at such
           addresses as they may advise from time to time.

           IN WITNESS WHEREOF the Parties hereto have duly executed this
Agreement by their authorized signatories effective on the date first above
written.

1.         AFRICAN CONTINENT

           (a)        Masana Holdings Ltd - South Africa

                      Lion retained to conduct technical due diligence and
                      provide financial advice on a range of privatised and
                      other mining opportunities. Where there is an opportunity
                      either to sell or J/V such opportunities, AZCO will have
                      first option on any qualifying property. Owners of Masana
                      are prominent political and business leaders in the new
                      black Africa.

           (b)        Botswana

                      Lion at an advanced stage in negotiating the flotation of
                      a new Botswana mining finance company with its own
                      capital. Lion to be a capital partner. Code: KYS.

           (c)        Diamonds

                      Due to Lion's previous exclusive agreements with
                      development and near-production companies, it is not
                      possible to include diamonds in this Lion/AZCO agreement.
                      Should the situation change in the future, Lion will
                      advise AZCO.

           (d)        Leading Southern African Merchant Bank

                      Corporate and Technical Advisory agreements under
                      negotiation together with potential fund management
                      business, together with the possibility of a large M&A
                      venture capital fund. These activities may produce AZCO
                      investment potential and wherever possible, AZCO will be
                      offered the chance to participate (subject to appropriate
                      consents).

2.         MIDDLE EAST

           Lion has numerous technical advisory agreements with Saudi Groups as
           well as a financial Venture under discussion. Although at this stage
           these agreements cover the technical evaluation of mining projects,
           which are part of the restructuring of the Saudi Arabian mining
           industry, it is possible that Venture opportunities could arise which
           may be offered to AZCO (subject to appropriate consents).

3.         NORTH AMERICA

           Lion's current activity for exclusion is M & A related. In M & A
           situations, Lion will offer the opportunity to AZCO wherever
           possible.

4.         LATIN AMERICA

           No conflicting business.

5.         UNITED KINGDOM & EUROPE

           Discussions under way relating primarily to fund management business.

6.         M&A

           With junior mining equity markets at their lowest levels since 1979,
           the greatest acquisition opportunity is likely to arise among those
           projects under development by an underfunded junior. Lion will use
           its best endeavours to select qualifying juniors for merger,
           acquisition or Venture by AZCO. Lion's `superfund' negotiations are
           aimed at facilitating this endeavour.

                              MANAGEMENT AGREEMENT


This agreement dated August 15, 1994 by and between AZCO Mining Inc., a Delaware
corporation (the "Company") and Alan P. Lindsay, the corporate officer, (the
"officer").

Whereas the officer has rendered valuable services to the Company and the
Company desires to be assured that the executive will continue rendering such
services to the Company;

Whereas the officer is willing to continue to serve the Company but desires
assurance that he will be protected in the event of any change in control;

Now therefore, in consideration of the mutual covenants and promises herein, the
parties agree as follows.

The Company agrees that if

1.         there is a change of control of the Company, and

2.         the officer leaves the employment of the Company, for whatever reason
           (other than discharge for cause, death or disability) within six
           months after such acquisition of control

a.         the officer shall receive as a lump sum, a cash payment in the amount
           not to exceed 299% of the base amount as defined in IRC Section 280G
           (b) (3); provided, that in any event, the amount payable under this
           clause (a) shall not exceed the maximum amount payable to the officer
           without the imposition of any excise taxes under the provisions of
           Section 4999 of the Internal Revenue Code as that section may be
           amended from time to time.

b.         the officer will continue to be covered by all of the Company's
           medical, health, life and dental plans for 24 months after such
           change of control.

The amounts paid to the officer hereunder shall be considered severance pay in
consideration of the past services he has rendered to the Company and in
consideration of his continued service from the date hereof to his entitlement
to those payments. The officer shall have no duty to mitigate his damages by
seeking other employment. Should the officer actually receive other payments
from any such other employment, the payments called for hereunder shall not be
reduced or offset by any future earnings.

as used herein, the term "change in control" shall mean either

1.         the acquisition of (whether direct or indirect) shares in excess of
           20 percent of the outstanding shares of common stock of the Company
           by a person or group of persons,


<PAGE>   2



           other than through a public equity offering by the Company, or

2.         the occurrence of any transaction relating to the Company required to
           be described pursuant to the requirements of item 6 (e) of schedule
           14A of the Securities and Exchange Commission under the Securities
           and Exchange Act of 1934, or

3.         any change in the composition of the board of directors of the
           Company resulting in a majority of the present directors not
           constituting a majority provided, that in making such determination
           directors who were elected by, or on the recommendation of, such
           present majority, shall be excluded.

The arrangements called for by this agreement are not intended to have any
effect on the officer's participation in any other benefits available to
executive personnel or to preclude other compensation or additional benefits as
may be authorized by the board of directors from time to time.

This agreement shall be binding and shall inure to the benefit of the respective
successors, assigns, legal representatives and heirs to the parties hereto.

This agreement shall terminate, even though prior to the acquisition of any
control of the Company as defined here, if the officer shall voluntarily resign,
retire, become permanently and totally disabled, voluntarily take another
position requiring a substantial portion of his time, or die. This agreement
shall also terminate if the executive's employment as an officer of the Company
shall have been terminated for any reason by the board of directors of the
Company as constituted prior to any acquisition of control of the Company as
defined herein.

In witness whereof, the parties have signed this agreement this 15th day of
August, 1994.

assurance that he will be protected in the event of any change in control;

Now therefore, in consideration of the mutual covenants and promises herein, the
parties agree as follows.

The Company agrees that if

1.         there is a change of control of the Company, and

2.         the officer leaves the employment of the Company, for whatever reason
           (other than discharge for cause, death or disability) within six
           months after such acquisition of control

a.         the officer shall receive as a lump sum, a cash payment in the amount
           not to exceed 299% of the base amount as defined in IRC Section 280G
           (b) (3); provided, that in any event, the amount payable under this
           clause (a) shall not exceed the maximum amount payable to the officer
           without the imposition of any excise taxes under the provisions of
           Section 4999 of the Internal Revenue Code as that section may be
           amended from time to time.

b.         the officer will continue to be covered by all of the Company's
           medical, health, life and dental plans for 24 months after such
           change of control.

The amounts paid to the officer hereunder shall be considered severance pay in
consideration of the past services he has rendered to the Company and in
consideration of his continued service from the date hereof to his entitlement
to those payments. The officer shall have no duty to mitigate his damages by
seeking other employment. Should the officer actually receive other payments
from any such other employment, the payments called for hereunder shall not be
reduced or offset by any future earnings.

as used herein, the term "change in control" shall mean either

1.         the acquisition of (whether direct or indirect) shares in excess of
           20 percent of the outstanding shares of common stock of the Company
           by a person or group of persons,


<PAGE>   10



           other than through a public equity offering by the Company, or

2.         the occurrence of any transaction relating to the Company required to
           be described pursuant to the requirements of item 6 (e) of schedule
           14A of the Securities and Exchange Commission under the Securities
           and Exchange Act of 1934, or

3.         any change in the composition of the board of directors of the
           Company resulting in a majority of the present directors not
           constituting a majority provided, that in making such determination
           directors who were elected by, or on the recommendation of, such
           present majority, shall be excluded.

The arrangements called for by this agreement are not intended to have any
effect on the officer's participation in any other benefits available to
executive personnel or to preclude other compensation or additional benefits as
may be authorized by the board of directors from time to time.

This agreement shall be binding and shall inure to the benefit of the respective
successors, assigns, legal representatives and heirs to the parties hereto.

This agreement shall terminate, even though prior to the acquisition of any
control of the Company as defined here, if the officer shall voluntarily resign,
retire, become permanently and totally disabled, voluntarily take another
position requiring a substantial portion of his time, or die. This agreement
shall also terminate if the executive's employment as an officer of the Company
shall have been terminated for any reason by the board of directors of the
Company as constituted prior to any acquisition of control of the Company as
defined herein.

In witness whereof, the parties have signed this agreement this 7th day of
October, 1997.

<PAGE>   11

           (d) All fees pursuant to this Section 3.5 shall be paid by the
Company in U.S. Dollars unless the Board of Directors determines otherwise. For
this purpose, the U.S. Dollar equivalent of New Mexican Pesos or any other
currency shall be determined on the basis of the New York foreign exchange
selling rate for the day three business days prior to such payment as reported
in The Wall Street Journal, Eastern Edition.


3.6        Assumptions. Underlying Expense Reimbursement and Fee Structure. The
expense reimbursement and fee structure contemplated by this Agreement has been
negotiated taking into account the applicable Mexican tax rules and rates and
Mexican laws and regulations in effect on the date hereof and current

be necessary to enable the Operator to decide whether or not to proceed to the
feasibility study stage with respect to the Project. The Operator shall use
reasonable efforts to complete by the date 36 months after the date hereof all
such activities that the Operator deems necessary for such purpose. If such
activities are not completed by such date, then, unless the failure to complete
such activities by such date is attributable to reasons beyond the Operator's




<PAGE>   12

reasonable control, the operator shall make payments to Azco, quarterly in
arrears, at a rate of $100,000 per year commencing on the date 39 months after
the date hereof and continuing until such activities are completed. Such
payments, if commenced, shall be suspended during any period when the Operator
is unable, for reasons beyond its reasonable control, to use all reasonable
efforts to complete such activities.


3.9        Development. If after the preparation of a bankable feasibility study
the Operator recommends to the Board of Directors that the Project be developed,
the Board of Directors authorizes such development and Project Debt Agreements
are executed pursuant to Section 4.2, then the operator shall promptly initiate
such development on behalf of the Company and shall diligently proceed to
complete such development so long as financing continues to be available under
such Project Debt Agreements and the current political and economic conditions
continue to be acceptable to the operator and the Board of Directors.


3.10       Discussions of Possible Sale. If the Operator recommends not to
proceed to the feasibility stage or not to develop the Project, then either
Shareholder will, at the request of the other Shareholder, meet to discuss a
possible sale of the Shares held by the Shareholder not requesting such meeting
to the Shareholder requesting such meeting.


4.         Financing.


4.1        Shareholder Financing through Development. (a) Each Shareholder shall
provide its Respective Share of cash required for activities deemed by the
Operator to be necessary to enable the Company to decide whether or not to
proceed to the feasibility study stage with respect to the Project; provided
that Azco shall not be obligated to provide more than $3,000,000 for such
activities other than (i) the acquisition of land and mining claims, concessions
and any other related rights, and (ii) the payment of lease, royalty, and other
similar payments for land and mining claims, concessions and any other related
rights. Each Shareholder shall provide such cash in U.S. Dollars unless the
Board of Directors requests such cash in the form of new Mexican pesos, in which
case each Shareholder shall provide such pesos and the U.S. Dollar equivalent
thereof shall be determined for the purpose of this Section 4.1(a) on the basis
of the New York foreign exchange selling rate for the day the Company receives
such pesos as reported in The Wall Street Journal, Eastern Edition. The
activities referred to in the first sentence of this Section 4.1(a) (and in
clause (i) of the proviso thereto) shall include the purchase of mineral
properties and related rights owned by the Bienvenidos Syndicate situated
adjacent to property owned by the Company for a purchase price of 400,000
Canadian Dollars or such other amount as may be approved by the Board of
Directors.

           (b) If the Operator recommends, and the Board of Directors
authorizes, proceeding to the feasibility study stage with respect to the
Project, each Shareholder shall provide its Respective Share of the cash
required in connection with such feasibility study or studies as may be approved
by the Board of Directors.

           (c) If after the preparation of a bankable feasibility study the
Operator recommends, and the Board of Directors authorizes, proceeding to
development of the


<PAGE>   13


Project and Project Debt Agreements are executed pursuant to Section 4.2, then
each Shareholder shall provide its


         Respective Share of the cash required for development of the Project,
including an appropriate amount of working capital for the operation of the
Project, as may be approved by the Board of Directors so long as financing
continues to be available under such Project Debt Agreements and the current
political and economic conditions continue to be acceptable to the Operator and
the Board of Directors.


           (d) Each Shareholder shall provide such cash as may be required
pursuant to this Section 4.1 on the basis of schedules therefor prepared by the
Operator and approved by the Board of Directors and shall receive Shares or
Subordinated Debt therefor as determined by the Board of Directors. Any such
Shares shall be sold at a price equal to book value as reasonably determined by
the Board of Directors, and any such Subordinated Debt shall be sold at a price
equal to par. Notwithstanding the foregoing, in the event cash is required for
activities referred to in Section 4.1(a) but Azco is no longer obligated to
provide its Respective Share of such cash in accordance with the proviso to
Section 4.1(a), the PD Shareholder shall provide the required cash, the cash
attributable to Azco's Respective Share shall be provided by the PD Shareholder
on behalf of Azco and the PD Shareholder and Azco shall receive therefor Shares
or Subordinated Debt as may be approved by the Board of Directors. No payments
by the PD Shareholder of cash for the activities referred to in Section 4.1(a)
when Azco is no longer obligated to provide its Respective Share of such cash in
accordance with the proviso thereto shall result in a reduction of Azco's
Respective Share.


           (e) Notwithstanding the foregoing provisions of this Section 4.1,
either Shareholder may, by notice to the other Shareholder and the Operator,
within 15 days of the receipt of a schedule calling for the provision of cash
for activities referred to in Section 4.1(b) or (c), elect not to provide such
cash and to accept possible dilution under the next sentence. If a Shareholder
makes such an election, the other Shareholder may elect to provide such cash and
to receive Shares therefor (and for the corresponding cash provided with respect
to its Respective Share) at a price equal to book value as reasonably determined
by the Board of Directors.


4.2        Project Financing of Development. (a) If after the preparation of a
bankable feasibility study the operator recommends and the Board of Directors
authorizes, proceeding to development of the Project, then, the PD Shareholder
shall use all reasonable efforts to procure, as may be approved by the Board of
Directors, financing for such development consisting of Senior Project Debt in
an amount (not exceeding 60% of the estimated cost of such development,
including an appropriate amount of working capital for the operation of the
Project) for which financing is available at an interest cost and on other terms
and conditions that the PD Shareholder believes are reasonable and appropriate
under the circumstances. If the Senior Project Debt lenders are willing to
extend such financing to cover all or part of the cost of the feasibility study
on terms and conditions that the PD Shareholder believes are reasonable and
appropriate under the circumstances, the financing shall cover all or such part
of the cost of the feasibility study in order to reduce the amount of financing
required by the Shareholders under Section


<PAGE>   14


4.1(c). Neither the PD Shareholder nor any of its Affiliates shall be obligated
to provide any guaranties or other credit support for such financing, except
that, if required by such lenders, the PD Shareholder shall provide a completion
guaranty from PDC, acceptable in substance and form to PDC, for which the
Company shall pay PDC an annual fee, payable quarterly in arrears, until the
earlier of (i) the termination of such guaranty and (ii) the date 12 months from
the date the Company issues its first invoice for the sale of copper cathode and
which may be payable in Subordinated Debt, equal to 5% of the principal amount
of such Senior Project Debt from time to time outstanding.

           (b) In its discretion, the PD Shareholder or any Affiliate of the PD
Shareholder may provide such Senior Project Debt, or additional credit support
for such Senior Project Debt, as may be approved by the Board of Directors. The
PD Shareholder or any Affiliate of the PD Shareholder will be paid for providing
such Senior Project Debt or such additional credit support as may be approved by
the Board of Directors, but no Senior Project Debt under this Section 4.2(b) is
to be more costly to the Company or otherwise on less favourable terms than
available Senior Project Debt of the kind contemplated by Section 4.2(a). In the
event the PD Shareholder or any Affiliate of the PD Shareholder decides to
provide such Senior Project Debt, the PD Shareholder shall specify the principal
amount and the terms and conditions thereof by written notice to Azco; within 30
days of receipt of such notice, Azco may but shall not be obligated to notify
the PD Shareholder that it or one of its Affiliates will provide its Respective
Share of such principal amount on terms and conditions identical to those so
specified.

           c) The Shareholders, on a pro rata basis, will pledge their Shares
and the Company will mortgage the Project and assign any sales contracts for
Products to be produced by or from the Project as security for Senior Project
Debt as may be requested or approved by the Board of Directors.


4.3        Financing of Operations. (a) It is intended that operations of the
Project will be financed from the cash flow of the Project. Notwithstanding this
intention, should additional cash be required for operations and not be
available from institutional lenders on terms deemed reasonable by the Board of
Directors, each Shareholder shall provide its Respective Share of such cash on
the basis of schedules therefor prepared by the Operator and approved by the
Board of Directors and shall receive Shares or Subordinated Debt therefor as
shall be determined by the Board of Directors. Any such Shares shall be sold at
a price equal to book value as reasonably determined by the Board of Directors,
and any such Subordinated Debt shall be sold at a price equal to par.


           (b) Notwithstanding the foregoing provisions of this Section 4.3,
either Shareholder may, by notice to the other Shareholder and the Operator,
within 15 days of the receipt of a schedule calling for the provision of cash
under this Section 4.3, elect not to provide such cash and to accept possible
dilution under the next sentence. If a Shareholder makes such an election, the
other Shareholder may elect to provide such cash and to receive Shares therefor
(and for the corresponding cash provided with respect to its Respective Share)
at a price equal to book value as determined by the Board of Directors.


5.         Programs and Budgets.



<PAGE>   15


           The Operator shall prepare a program and budget for each calendar
year beginning with 1996, and shall submit such program and budget to the Board
of Directors (and a copy to each director) by December 31 of the preceding year.
Such programs and budgets may cover such longer periods as the Operator deems
appropriate. The Board of Directors shall review and consider approval of each
such program and budget at the Board's next meeting following its submission.
Any program and budget approved by the Board of Directors may be revised or
supplemented from time to time by the Board of Directors. The Operator shall
notify the Board as soon as practicable of any material departure from an
approved program and budget.


6.         Accounting.


6.1        Books and Records Except as otherwise determined by the Board of
Directors, the Company shall keep, or cause to be kept, books and records in
accordance with accounting practices generally accepted in the United States, so
as accurately to record all receipts of funds from or for the account of the
Company and disbursements thereof. All books and records maintained pursuant to
this Section shall be open to the inspection and examination of, or made
available to, the directors, officers, accountants or consultants of any
Shareholder at the locations where such books, records and information are kept
in the ordinary course of business at such reasonable times as may be specified
in reasonable prior written notice to the Company.


6.2        Audit. The auditors of the Company shall be Price Waterhouse LLP or
such other accounting firm of international standing selected from time to time
by the Board of Directors.


6.3        Fiscal Year. The fiscal year of the Company shall be the calendar
year or such other year as shall be determined by the Board of Directors or as
otherwise required by Mexican law.


7.         Transfers of Interests; Rights of First Refusal.


7.1        General Prohibition. Except as permitted by or provided for in this
Agreement, no Shareholder other than the PD Shareholder shall sell, assign,
convey or otherwise dispose of, or directly or indirectly mortgage, pledge or
otherwise create or suffer to exist a lien, charge or other encumbrance or
security interest in any of the Shares, Subordinated Debt or corresponding
rights under this Agreement that it holds. Any sale, assignment, conveyance or
other disposition, mortgage, lien, charge, encumbrance, or security interest
permitted by or provided for in this Agreement shall be made in accordance with
applicable law and with any applicable provisions of the Project Debt
Agreements.


7.2        Sales or Pledges by Shareholders Other Than the PD Shareholder. (a)
Should any Shareholder other than the PD Shareholder solicit or encourage,
directly or indirectly,


<PAGE>   16


any inquiry or proposal for the purchase of the Shares and Subordinated Debt
that it holds and the corresponding rights under this Agreement, it shall
promptly inform the Board of Directors of any such inquiries or proposals and
provide the Board with copies of all related documentation.

(b) Should any Shareholder (the "Selling Shareholder") other than the PD
Shareholder wish to sell the Shares and Subordinated Debt that it holds and the
corresponding rights under this Agreement, it must first obtain a bona fide
written offer for all such Shares, Subordinated Debt and rights and give the PD
Shareholder written notice identifying the offeror and describing the price and
each of the terms and conditions of such bona fide offer. Within 45 days of its
receipt of such notice the PD Shareholder shall notify such Selling Shareholder
as to (i) whether it wishes to purchase such Shares and Subordinated Debt and
rights itself on the terms and conditions contained in such bona fide offer and
described in such notice, and (ii) if it does not wish to so purchase such
Shares and Subordinated Debt and rights, whether it approves of the offeror
becoming a Shareholder, which approval shall not be unreasonably withheld. If
the PD Shareholder shall notify such Selling Shareholder that it wishes to
purchase such Shares and Subordinated Debt and rights at such price and on such
terms and conditions, the PD Shareholder and the Selling Shareholder shall
consummate such transaction as promptly as is reasonably practicable but in any
event not more than 30 days after the end of such 45-day period. If in such
notice the PD Shareholder shall decline to purchase such Shares and Subordinated
Debt and rights at such price and on such terms and conditions and the PD
Shareholder shall approve the identified offeree, then such Selling Shareholder
shall be free to sell such Shares and Subordinated Debt and rights to such
offeree on such terms and conditions at any time within 30 days after the end of
such 45-day period.

(c) Following payment in full of all amounts due with respect to the Senior
Project Debt, Azco may, with the approval of the Board of Directors' pledge all
(but not less than all) its Shares, Subordinated Debt and the corresponding
rights under this Agreement to any institutional lender. Any sale of such Shares
in connection with such pledge shall comply in all respects with the provisions
of Section 7.2(b) and 7.3 as though the seller were the Selling Shareholder.


7.3        Substitution of Shareholder. No transfer of Shares, Subordinated Debt
and corresponding rights under this Agreement pursuant to Section 7.2 (except
for such transfer to the PD Shareholder) shall be effective until (i) the
transferee has delivered to all Shareholders a written instrument, reasonably
satisfactory to the PD Shareholder, assuming the obligations of the Selling
Shareholder hereunder, together with such evidence and counsel opinions as the
PD Shareholder may reasonably request confirming the due authorization,
execution and enforceability of such instrument, and (ii) the transferee has
received all consents of third Persons necessary for compliance with the terms
of this Agreement. Upon the effectiveness of a transfer of Shares, Subordinated
Debt and corresponding rights under this Agreement pursuant to this Section 7.3,
the Shareholder making the transfer shall be relieved of all obligations
hereunder arising after the effective date of such transfer.


7.4        Sales by the PD Shareholder. The PD Shareholder and any Affiliate of
the PD Shareholder who is a Shareholder shall be free to sell, assign, convey or
otherwise


<PAGE>   17


dispose of, mortgage, pledge or otherwise create or suffer to exist a lien,
charge or other encumbrance or security interest in any or all of the Shares,
Subordinated Debt or corresponding rights under this Agreement that it holds. In
the event the PD Shareholder (or any such Affiliate of the PD Shareholder)
assigns its rights under this Agreement to a transferee of a majority in
interest of the Shares, then, upon (i) delivery by such transferee to all other
Shareholders of a written instrument, reasonably satisfactory to such other
Shareholders, assuming the obligations of the PD Shareholder under Section 4.2,
and the other obligations of the PD Shareholder (or such Affiliate) hereunder
with respect to the Shares so transferred (including, if transferred, the
obligations as operator of the Project), together with such evidence and counsel
opinions as such other Shareholders may reasonably request confirming the due
authorization, execution and enforceability of such instrument, and (ii) receipt
by the transferee of all consents of third persons necessary for compliance with
the terms of this Agreement, the PD Shareholder (or such Affiliate) shall be
relieved of all obligations under Section 4.2, and such other obligations
hereunder with respect to the Shares so transferred (including, if transferred,
the obligations as Operator), arising thereafter, except that the PD Shareholder
(or such Affiliate) shall not be relieved of any obligations arising thereafter
under Section 4.2 unless (x) the other Shareholders shall approve in writing the
transferee, which approval shall not be unreasonably withheld, or (v) the
operator shall have certified to the other Shareholders that (A) it has
recommended not proceeding to the feasibility stage with respect to the Project
or (B) if the Project has proceeded to the feasibility study stage, either (1)
the feasibility study prepared with respect to the Project was either not
bankable or not satisfactory to the Operator or (2) the Operator has recommended
not to proceed to development.


8.       Competition; Business Opportunities.


         Nothing in this Agreement shall prevent any Shareholder or Affiliate of
any Shareholder, at any time and without notice to or agreement by any other
Shareholder, from entering into or continuing any business, whether or not
competitive with the Company, or acquiring or exploiting any mining rights,
whether or not in the vicinity of the Project, and none of the Affiliates of any
Shareholders shall have any obligation to offer business or other opportunities
to the Company or any other Shareholder.


9.       Confidentiality.


         Each Shareholder shall hold all information concerning the Company and
the operations of any Shareholder not otherwise generally available to the
public ("Confidential Information") in strict confidence and shall not, without
the prior written consent of each Shareholder affected, use or disclose such
information to anyone other than a Shareholder and its Affiliates and directors,
key employees, accountants, consultants and other advisors of the disclosing
Shareholder and its Affiliates who such Shareholder shall ensure will hold such
information in strict confidence as contemplated by this Section 9.
Notwithstanding the foregoing, (i) any Shareholder other than the PD Shareholder
may disclose Confidential Information to any prospective purchaser of all of the
Shares, Subordinated Debt and corresponding rights under this Agreement that it
holds and the PD Shareholder and any Affiliate of the PD Shareholder who is a
Shareholder may disclose Confidential Information to a prospective purchaser of
any or 


<PAGE>   18


all of the Shares or Subordinated Debt and corresponding rights under this
Agreement that it holds, provided that any such prospective purchaser shall
first execute a confidentiality agreement containing provisions substantially
equivalent to this Section 9, and (ii) any Shareholder or any Affiliate thereof
may disclose Confidential Information if it believes in good faith that such
disclosure is required by applicable law, provided that prior to making any such
disclosure pursuant to this clause (ii) such Shareholder shall give written
notice (identifying such law and describing the general nature of such
disclosure) to, and consult with, each other Shareholder, unless such disclosure
is required immediately by law, in which case such Shareholder may disclose
Confidential Information to the extent required and shall immediately report in
writing the content of such disclosure and the reason therefor to each other
Shareholder.
