                   Notes to Consolidated Financial Statements
                             June 30, 1997 and 1998
                                   (Unaudited)

(1) Summary of Significant Accounting Policies
    The Company.
         Environmental Remediation Holding Corporation, (ERHC), was incorporated
         on May 12, 1986 in Colorado as Valley View Ventures,  Inc.,  (VVV). Its
         name  was  changed  to  Regional  Air  Group  Corporation,  (RAGC),  on
         September  20,  1988,  and then to  Environmental  Remediation  Holding
         Corporation on August 29, 1996. VVV was created in 1986 as a blind pool
         to seek a merger opportunity with a viable operating  company.  In 1988
         the company  acquired,  via a reverse  merger,  Mid-Continent  Airlines
         which was a regional "feeder" airline operating as Braniff Express.  On
         September 28, 1989, Braniff Airlines filed Chapter 11 Bankruptcy.  This
         event proved to be catastrophic  to the then operating  business of the
         Company.  RAGC liquidated its assets and liabilities shortly thereafter
         and  remained  dormant  until its  reverse  merger  with  Environmental
         Remediation Funding Corporation on August 19, 1996.

   Nature of operations.
         ERHC operates in the environmental remediation industry and the oil and
         natural gas  production  industry  from its corporate  headquarters  in
         Jericho, New York, and its operating offices in Lafayette, Louisiana.

   Use of estimates
         The consolidated  financial statements have been prepared in conformity
         with  generally  accepted  accounting  principles.   In  preparing  the
         financial  statements,  management  is required to make  estimates  and
         assumptions  that affect the reported amounts of assets and liabilities
         as of the dates of the  statements of financial  condition and revenues
         and  expenses  for the years then ended.  Actual  results  could differ
         significantly  from those estimates.  The following  summarize the more
         significant  accounting  and  reporting  policies and  practices of the
         Company:

   Principles of consolidation
         The consolidated  financial  statements include the accounts of SSI and
         BAPCO,  its  wholly  owned  subsidiaries.   Intercompany  accounts  and
         transactions  have been eliminated in  consolidation.  The consolidated
         financial  statements  for the nine months ended June 30, 1997 and 1998
         include  all  adjustments  which  in  the  opinion  of  management  are
         necessary for fair presentation.

    Net loss per share
          Net loss per share - basic is computed by dividing the net loss by the
         number of shares  outstanding  during the period.  Net loss per share -
         diluted  is  not  presented  because  the  inclusion  of  common  share
         equivalents would be anti-dilutive.

     DRSTP geological data
         In July 1997, the Company acquired  substantial geologic data and other
         information  from an  independent  source in  exchange  for one million
         shares  of  the  Company's  common  stock.  This  data  was  valued  at
         $2,000,000  based the  agreement  with the seller  that  Company  would
         repurchase  these  shares for  $2,000,000  at a rate of 25% per quarter
         should the seller so choose. The Company expensed this acquisition cost
         immediately.

(2) Significant Acquisitions
         The Company acquired 100% of the issued and outstanding common stock of
         Environmental   Remediation   Funding   Corp.,   (ERFC),   a   Delaware
         corporation,  effective  on August 19,  1996,  in a reverse  triangular
         merger,  which has been accounted for as a  reorganization  of ERFC. At
         the same time the  Company  changed  its name from  RAGC.  Prior to the
         merger ERFC had acquired certain environmental remediation equipment in
                                       F-6
<PAGE>
                  ENVIRONMENTAL REMEDIATION HOLDING CORPORATION
                   Notes to Consolidated Financial Statements

(2) Significant Acquisitions (Continued)
         exchange  for  common  stock.  ERFC then  employed  the  seller of this
         equipment  as an outside  consultant  in  exchange  for  common  stock.
         Subsequently,   ERFC  was  unable  to  enter  into  the   environmental
         remediation  contracts  it had  hoped to and asked  the  consultant  to
         become the Chairman, President and CEO of ERFC.

         At the time of the acquisition of ERFC by RAGC, ERFC owned 100% of Site
         Services,  Inc., (SSI).  ERFC had acquired SSI from Bass  Environmental
         Services Worldwide, Inc., (BESW), a company controlled by the Chairman,
         President  and CEO of ERFC.  SSI had always been an  inactive  company,
         except  for  certain   environmental   remediation  licences  which  it
         continues to hold.

         On  April  9,  1997,  the  Company  acquired  100%  of the  issued  and
         outstanding common stock of Bass American  Petroleum Company,  (BAPCO),
         which was  accounted  for as a  purchase.  BAPCO  had been an  inactive
         company for several years previously,  however BAPCO owned a variety of
         oil well production enhancing  equipment,  which is proprietary to, but
         not  patented  by  BAPCO.  The  transaction  was in  essence  an  asset
         acquisition. At the time of the acquisition BAPCO was 100% owned by the
         Chairman,  President  and CEO of ERHC.  As such,  the  acquisition  was
         accounted for at historical  cost. The Company has begun using BAPCO as
         the operator of the various oil and natural gas leases it has acquired.

(3)  Liquidity
         The  Company's  current   liabilities  exceed  its  current  assets  by
         $1,626,331,  reflecting a possible lack of liquidity. The Company is in
         ongoing  negotiations  to raise general  operating  funds and funds for
         specific  projects.  As  discussed  in notes 7, 10 and 17, the  Company
         raised an additional $1,100,000 in October 1997, $4,300,000 in November
         1997, $536,000 in April 1998, $2,011,000 in June 1998 and $1,475,000 in
         July and August 1998.  The Company has  negotiated two lines of credit,
         one for  $15,000,000  and one for  $5,000,000.  These  lines of  credit
         cannot be drawn upon until the Company's current registration statement
         on form S-1 is  declared  effective.  Both of these lines of credit are
         convertible  into shares of the Company's common stock on terms similar
         to the convertible debt discussed in note 7. As discussed in note 5 and
         16a,  the  Company  has also  received  a letter of  intent  for a firm
         commitment  from a  registered  broker/dealer  to raise  an  additional
         $50,000,000  in  convertible  debt.  However there is no assurance that
         such financing will be obtained.

(4) Equipment
         Environmental  remediation  equipment was purchased by ERFC in exchange
         for common stock. The Company recorded this equipment based on the fair
         value of the common  stock given up. At the date of  acquisition,  ERFC
         was a privately held company,  therefore there was no market for ERFC's
         stock. At the time of negotiations for this transaction, it was an arms
         length transaction between unrelated parties.  The parties negotiated a
         value  of $5 per  share  for a total of  744,000  shares  valuing  this
         transaction  at  $3,720,000.  The Company has chosen to depreciate  the
         equipment  using the straight line method over its estimated  remaining
         useful life of fifteen years.  Expenditures for maintenance and repairs
         are charged to operations as incurred.

         In the BAPCO  acquisition the Company acquired  ownership of all rights
         to BAPCO's  proprietary  oil well reworking  tool,  "the BAPCO Tool" as
         well as other oil and natural gas well reworking equipment. The control
         of this  proprietary  tool has enhanced the  Company's  position to the
         extent  that it would not have been able to enter into the  contract to
         control the Utah oil fields and the  reworking  of the  Indonesian  oil
         fields.  The control of this tool also enabled the  acquisition  of the
         200 Texas oil wells to be  economically  feasible to a greater  extent.
         The Company received two completed "BAPCO" tools which were ready to be
         placed in service in this transaction. The Company valued the equipment
         received at  historical  cost  amounting  to $250,000  each for the two
         tools,  totalling $500,000.  BAPCO was controlled by the CEO of ERHC at
         the time of the  BAPCO  acquisition,  therefore  the  Company  believes
         historical cost is the appropriate basis for valuing the transaction.

                   Notes to Consolidated Financial Statements

(4) Equipment (Continued)
         The Company is depreciating this tool and technology over ten years.

         Depreciation  expense for the nine months  ended June 30, 1997 and 1998
         was $196,417and $377,080 respectively.

(5) Crude oil reserves
         At September  30,  1996,  the Company had no oil and gas  reserves.  In
         March 1997,  the Company  acquired an  undivided  7/8 interest in a 100
         well  lease  located in the  Gunsite  Sand  Lease in Ector,  Texas,  in
         exchange for 300,000 shares of the Company's  common stock. The Company
         valued  this  transaction  at the  closing  price  of stock  given  up,
         $1.03125,  or a total of $309,375.  The Company received an independent
         evaluation of this field which  reflected  1,000,000  barrels of proved
         oil  reserves.  In March 1997,  the Company  acquired an undivided  7/8
         interest in a 100 well lease  located in the Woodbine  Sand Lease Block
         in  Henderson  County,  Texas,  in exchange  for 200,000  shares of the
         Company's  common stock.  The Company  valued this  transaction  at the
         closing price of the stock given up, $1.03125,  or a total of $206,250.
         The Company  received  an  independent  evaluation  of this field which
         reflected  1,500,000  barrels of proved  oil  reserves.  These  reserve
         reports,  as amended in March 1998,  reflect  values of $4,831,323  for
         Gunsite and  $9,504,323 for Woodbine.  A separate  reserve report is in
         the process of being prepared, which the Company will use to adjust the
         quantity of barrels of reserves if the subsequent  report is materially
         different.

         Both  acquisitions  also included all existing  equipment on site.  The
         Company has not  recorded  the fair market  value of the  equipment  in
         place,  as all of such equipment has minimal scrap value,  which is the
         only valuation  method available due to the  non-operational  status of
         the  wells at  acquisition.  The  Company  expects  to  capitalize  and
         depreciate repairs which are believed to extend the useful life of such
         existing  equipment beyond one year, as well as the cost of replacement
         equipment.

         On September 29, 1997, the Company entered into an agreement to acquire
         22 oil, gas and mineral leases located in Uintah and Duchesne Counties,
         Utah from three joint  owners.  The  purchase  agreement  was closed on
         October  8,  1997,  at which time the the  Company  received  the lease
         assignment.  The  terms  of the  acquisition  are for the  Company  pay
         $250,000 in cash, issue 250,000 shares of the Company's common stock at
         each of the following four dates: closing; December 30, 1997; March 30,
         1998 and June 30, 1998. The Company also was required to guarantee that
         the bid price on the date the Rule 144  restrictions  lapse  will be no
         less than $2.00 per share or the Company is  required  to either  issue
         additional  shares or to pay the  difference  in cash, at the Company's
         option.  The Company  also  granted  the sellers a 4% gross  production
         receipts  royalty to a maximum of  $677,000.  The Company is  currently
         evaluating the existing  reserve  reports and underlying  data on these
         leases  as well as has  contracted  another  independent  appraiser  to
         complete new reserve  reports for its use. The total  valuation of this
         transaction  is  $2,250,000  and is applied as  $375,800 of oil and gas
         reserves and $1,874,200 of equipment.

         In October 1997, the Company entered into an agreement to acquire a 3/8
         undivided  interest  in a natural  gas well that had been  plugged  and
         abandoned  approximately  10 years ago.  This  agreement  requires  the
         Company to pay the seller  $200,000 and 50,000  shares of the Company's
         common stock,  as well as to pay the Company's  proportionate  share of
         the costs to reenter this well.  The Company is also  required to carry
         the seller's  1/8  proportionate  share of the reentry  costs until the
         well is  producing.  The seller also owns an undivided  50% interest in
         the oil and gas lease on the  49,019  acres of land  contiguous  to the
         initial  well.  The  agreement  allows  the  Company  to  acquire a 3/8
         undivided interest in this lease by paying to the seller  approximately
         $343,000  each April for four years.  The Company  received the initial
         lease assignment on
                                       F-8

(5) Crude oil reserves (Continued)
         December 1, 1997.  The Company is  currently  evaluating  the  existing
         reserve  reports  and  underlying  data on these  leases as well as has
         contracted  another  independent  appraiser  to  complete  new  reserve
         reports for its use.

     Oil  production
         In late November 1997, test oil production  amounting to  approximately
         444 barrels was picked up from the tanks at the Gunsite Sand lease.  At
         that  time  the  Company  had  approximately  9 wells  back on line and
         pumping.  In late November and early December 1997, test oil production
         amounting to  approximately  1,292 barrels was picked up from the tanks
         at the 22 leases in Uintah and Duchesne Counties, Utah. The Company has
         11 wells in  production  in the Utah filed which  pumped  approximately
         6,300 barrels of oil in the third quarter. The Company is utilizing the
         successful  efforts  method of accounting for its oil and gas producing
         activities.  The Company expects to regularly assess proved oil and gas
         reserves for possible  impairment  on an aggregate  basis in accordance
         with SFAS 121.

        Depletion
         Depletion (including  provisions for future abandonment and restoration
         costs)  of all  capitalized  costs  of  proved  oil and  gas  producing
         properties  are  expensed  using  the   unit-of-production   method  by
         individual  fields  as the  proven  developed  reserves  are  produced.
         Depletion  expense for the nine months ended June 30, 1997 and 1998 was
         $0 and $3,595 respectively.

(6)  Master  service agreement
         In September 1996 Bass Environmental Services Worldwide,  Inc., (BESW),
         entered  into a  master  service  agreement  with  Chevron  to plug and
         abandon  oil  wells  located  in the Gulf of  Mexico  off the  coast of
         Louisiana. In April 1997, BESW assigned this contract to the Company in
         exchange for 3,000,000  shares of the Company's  common stock.  Chevron
         has  reissued the contract in the  Company's  name.  At the time of the
         acquisition, BESW was controlled by the CEO of ERHC. The Company valued
         this  acquisition on the basis of the par value of the Company's common
         stock  given up, or $300,  because no  historical  cost basis  could be
         individually  determined  and the contract has minimal  value until the
         Company has built or  purchased  the  equipment  to  commercialize  the
         contract. The Company expects to begin commercializing the agreement in
         late 1998.

(7) Notes payable
         The  Company  issued  two notes  payable to  stockholders  who are also
         officers and  directors in exchange for cash  amounting to  $1,362,906.
         These notes carry no stated maturity date and an 8.5% rate of interest.
         The Company has repaid $881,790 on these notes,  including  interest on
         one. The remaining note is convertible  into restricted stock at 50% of
         the  average  bid price  for the month in which the loan was made.  The
         conversion  is at the option of the  noteholder.  Accrued  interest  on
         these notes is, $0 and $155,824 for the nine months ended June 30, 1997
         and 1998.

         In  January  1997,  the  Company  issued  a note  payable  to a bank in
         exchange for $175,000 cash.  This note carried a maturity date of March
         15, 1997 and a 9.6875% interest rate. The Company is in default on this
         note. The default  interest rate is 13.6875%.  The Company and the bank
         had originally  expected to roll this note over into a long-term credit
         facility. The Company chose not to accept the long-term facility due to
         the terms  offered.  The Company  repaid this loan in full plus accrued
         interest on December 31, 1997.

         In November  and December  1997,  the Company  issued 5.5%  convertible
         senior  subordinated  secured notes due 2002 in exchange for $4,300,000

         common  stock at a  conversion  price  to be  determined  by so  stated
         formula,  but at a price no less than  $1.25 per  share.  If all of the
         notes are converted at the lowest possible price,  the Company would be
         required to issue  3,440,000  shares of common stock.  These notes also
         carried warrants for an additional  258,000 shares of common stock with
         an exercise price of $3.17 per share, or total  additional  proceeds to
         the Company of $817,860  in cash in the event all of the  warrants  are

         unsecured  notes due January 1999 in exchange for $300,000 cash.  These
         notes are  convertible  into shares of the Company's  common stock at a
         conversion  price  of  $1.50  per  share.  If all of  these  notes  are
         converted,  the Company  will be required  to issue  200,000  shares of
         common  stock.  These notes also  carried  warrants  for an  additional
         210,000  shares of common  stock  with an  exercise  price of $1.25 per
         share, or total additional  proceeds to the Company of $262,500 in cash
         in the event all of the warrants are exercised.

         In June 1998, the Company issued 12% convertible subordinated unsecured
         notes due December 1999 in exchange for $425,000 cash.  These notes are
         convertible  into shares of the Company's  common stock at a conversion
         price of $1.00 per  share.  If all of these  notes are  converted,  the
         Company will be required to issue 425,000 shares of common stock. These
         notes also carried warrants for an additional  531,250 shares of common
         stock  with an  exercise  price of $0.50  per  share  for the first two
         years, and $0.85 per share thereafter,  or total additional proceeds to
         the  Company of  $265,625  or  $451,563 in cash in the event all of the

         In  June  1998,  the  Company  issued  5.5%  convertible   subordinated
         unsecured  notes due June 2000 in exchange for $1,250,000  cash.  These
         notes are  convertible  into shares of the Company's  common stock at a
         conversion price to be determined by so stated formula. If all of these
         notes are converted,  using the  conversion  price of the issuance date
         ($0.69517),  the Company will be required to issue 1,798,124  shares of
         common  stock.  These notes also  carried  warrants  for an  additional
         230,000  shares of common  stock with an exercise  price of $0.8634 per
         share, or total additional  proceeds to the Company of $198,582 in cash
         in the event all of the warrants are exercised.

(8) Accrued salaries
         At June 30, 1997 and 1998 the Company has accrued  salaries  of, $0 and
         $1,757,699,  respectively,  for three officers.  These officers can, at
         their option,  convert these  salaries into common stock of the Company
         at the rate of  one-half  of the  average  bid  price of the  Company's
         common stock for the months in which the salary was earned.

(9) Income taxes
         The  Company  has  a  consolidated  net  operating  loss  carry-forward
         amounting to $23,556,215, expiring as follows: $3,404 in 2010, $728,748
         in 2011,  $16,913,052 in 2012 and $5,911,013 in 2013. The Company has a
         $9,420,000  deferred tax asset  resulting from the loss  carry-forward,
         for which it has  established  a 100%  valuation  allowance.  Until the
         Company's  current plans begin to produce  earnings it is unclear as to
         the ability of the Company to utilize these carry-forwards.

(10) Stockholders' equity
         The  Company  has  authorized  950,000,000  shares of $0.0001 par value
         common  stock and  10,000,000  shares of  $0.0001  par value  preferred

         less than $2.00 per share or the Company is  required  to either  issue
         additional  shares or to pay the  difference  in cash, at the Company's
         option.  The Company  also  granted  the sellers a 4% gross  production
         receipts  royalty to a maximum of  $677,000.  The Company is  currently
         evaluating the existing  reserve  reports and underlying  data on these
         leases  as well as has  contracted  another  independent  appraiser  to
         complete new reserve  reports for its use. The total  valuation of this
         transaction  is  $2,250,000  and is applied as  $375,800 of oil and gas
         reserves and $1,874,200 of equipment.

         In October 1997, the Company entered into an agreement to acquire a 3/8
         undivided  interest  in a natural  gas well that had been  plugged  and
         abandoned  approximately  10 years ago.  This  agreement  requires  the
         Company to pay the seller  $200,000 and 50,000  shares of the Company's
         common stock,  as well as to pay the Company's  proportionate  share of
         the costs to reenter this well.  The Company is also  required to carry
         the seller's 1/8  proportionate  share of the reentry costs,  estimated
         between $250,000 and $500,000,  until the well is producing. The seller
         also owns an  undivided  50%  interest  in the oil and gas lease on the
         49,019 acres of land  contiguous  to the initial  well.  The  agreement
         allows the Company to acquire a 3/8 undivided interest in this lease by
         paying to the seller approximately  $343,000 each April for four years.
         The Company  received the initial lease assignment on December 1, 1997.
         The Company is currently  evaluating the existing  reserve  reports and
         underlying  data on  these  leases  as well as has  contracted  another
         independent appraiser to complete new reserve reports for its use

         In December 1997, the Company  repurchased 250,000 shares of its common
         stock for $500,000 in cash. This was the first 25% quarterly repurchase
         agreed to by the Company  relating to the  1,000,000  shares  issued to
         acquire the DRSTP  geological data. In January 1998, the Company issued
         24,000  shares  valued at $61,218  and  assumed a  mortgage  payable of
         $28,782 to acquire a small office building in Utah,  valued at $90,000,
         from Unita Oil and Gas. In February  1998,  the Company  issued 282,000
         shares in exchange for $180,250 in cash and 104,664  shares in exchange
         for  services  valued at  $55,658.  In March 1998,  the Company  issued
         300,000 shares in exchange for a  subscription  receivable of $236,250,
         which was received in cash in April 1998. In

         efforts in closing the M III  contract  in Utah upon the joint  venture
         oil production  level of 4,000 barrels a day being  attained.  This two

         of 20,000 barrels a day being attained.

     Warrants
         In March 1998 the Company issued a warrant for 100,000 shares of common
         stock with an exercise  price of $1.20 per share,  or total proceeds of
         $120,000 in cash for the Company if all of the warrants are  exercised.
         This  warrant  was  issued  in  conjunction   with  entering  into  the

(11) Deferred compensation
         ERFC issued  755,043 shares of its common stock into escrow in exchange
         for services to be rendered by a consultant under a four year contract.
         These services were valued at $125,000 per year,  therefore the Company
         is amortizing this deferred  compensation  expense at a rate of $31,250
         per quarter.  This consultant later became ERFC's  Chairman,  President
         and CEO.

         On August 30,  1996,  the Company  issued  10,000  shares of its common
         stock, valued at $70,000, to an attorney for services to be rendered at
         below market rates for a period of 4 months.  Accordingly,  the Company
         amortized this expense over the term of the agreement.

(12) Commitments and contingencies
         The  Company  is  committed  to lease  payments  for 9  vehicles  under
         operating  leases  totalling  $52,292 and $20,043 for the fiscal  years
         ended September 30, 1998 and 1999, respectively.  The Company currently
         leases its office space and  operating  facilities  on a month to month
         basis.

(13) Segment information
         The Company has three distinct lines of business through its two wholly
         owned  subsidiaries,  Site  Services,  Inc.,  (SSI),  and Bass American
         Petroleum Company, (BAPCO), and a joint venture agreement. SSI operates

         transiting the Panama Canal. The Company is in final negotiations for a
         loan  which  would  allow it to begin  its  operations  in  Panama.  No
         principal identifiable assets yet exist for this line of business.

(14)   Sao Tome concession payment
         When the Company  entered into the joint venture  agreement in May 1997
         with the  Democratic  Republic of Sao Tome and Principe,  (DRSTP),  the
         Company was  required to pay a $5,000,000  concession  fee to the DRSTP
         goverment.  In September  1997,  the Company  received a Memorandum  of
         Understanding from the

         DRSTP  government  which allows the Company to pay this  concession fee
         within five days after the DRSTP files the relevant  official  maritime
         claims maps with the United Nations and the Gulf of Guinea  Commission.
         In December 1997, the Company paid $2,000,000 of this concession fee to
         the DRSTP from the proceeds of the convertible note offering.

(15) Letter of intent
         In  December  1997,  the  Company  received  a letter of intent  from a
         registered  brokerage house which contemplates a firm commitment public
         offering of  approximately  $50,000,000 of convertible debt securities.
         This offering,  if it proceeds, is contemplated for late 1998. There is
         no assurance that such offering will be consummated.

         In May,  1998,  the Company  received a letter of intent  from  another
         registered brokerage firm as a replacement of the December 1997, letter
         of  intent.  This  new  letter  of  intent  is for the same  terms  and
         conditions as the one it replaces.

(16) Investment in ST PETRO, S.A.
         In June 1998, in anticipation of the legal formation of ST PETRO,  S.A.
         by the government of the DRSTP,  the Company  forwarded  $20,000 of its
         expected $49,000 initial  investment in ST PETRO,  S.A. Once the entire
         amount  is  paid,  ERHC  will  own 49% of the  then  total  issued  and
         outstanding  common  stock of ST  PETRO.  ERHC  will  also  effectively
         control ST PETRO, S.A. by virtue that the CEO and President of ST PETRO
         are ERHC's CFO and COO respectively.

(17) Subsequent events
     a) Sao Tome concession payments
         On July 2, 1998 the Company paid  $1,000,000 of the  concession  fee to
         the  government  of the DRSTP.  On July 31,  1998 the  Company  paid an
         additional  $1,000,000 of the  concession  fee to the government of the
         DRSTP

     b) Notes payable
         In  July/August  1998 the Company  issued 8%  convertible  subordinated
         unsecured  notes due  July/August  2000 in exchange for  $1,200,000 and
         $275,000 cash. These notes are convertible into shares of the Company's
         common  stock at a  conversion  price  to be  determined  by so  stated
         formula.  If all of the  notes  are  converted,  the  Company  will  be
         required to issue 1,657,928 shares of common stock based on the formula
         on the dates of closing (an average of  $0.88966).  Warrants  were also
         issued to the  placement  agent  for an  additional  132,750  shares of
         common stock with an exercise price of $0.74375 and $0.73125 per share,
         or total  additional  proceeds to the Company of $98,423 in cash in the
         event all of the warrants are exercised.

Item 2. Management's Discussion and Analysis and Plan of Operation.

Environmental  Remediation  Holding  Corporation is an  independent  oil and gas
company engaged in the exploration,  development,  production and sales of crude
oil and natural gas properties with current  operations  focused in Texas, Utah,
and the Democratic Republic of Sao Tome and Principe in West Africa ("DRSTP").

The  Company's  strategy in the United States is to increase oil and natural gas
reserves,  production, and cash flow through (1) the exploration of its existing
acreage  position  in  Texas,  Utah,  and  the  DRSTP;  (2) the  acquisition  of
additional   properties  in  known  producing  areas  that  provide  significant
development and exploratory drilling potential;  (3) the exploration for oil and
natural gas reserves; (4) the maintenance of a low operating and cost structure;
and, (5) environmental remediation as it relates to the oil and gas industry.

The Company has acquired all of its oil and gas properties within the past year.
The Company's current development plans require substantial capital expenditures
in connection  with the  exploration,  development  and  exploitation of oil and
natural gas  properties.  Although the Company has  historically  funded capital
expenditures  through  a  combination  of  equity  contribution  and  short-term
financing  arrangements,  the Company's  ability to meet its  estimated  capital
expenditure  in Fiscal  year 1998 are  dependent  on the  Company's  ability  to
realize the proceeds of the Company's  contemplated  public debt offering of $50
million.

Should the  Company's  contemplated  debt  offering not proceed as planned,  the
Company  will  continue  to seek  alternative  sources  of funding to enable the
Company to meet its demands for cash to commercialize the various  agreements it
has  entered  into.  The Company  has sought  alternative  sources of funding to
provide interim  financing until such time as the anticipated  debt offering can
be completed.

The Private Stock Offering:

In order to meet certain current operating expenses,  during the period of April
1998 through June 1998,  the Company  received  gross  proceeds in the amount of
$371,850.00  from the sale of a total of 534,200 shares of the restricted  stock
in the Company,  $.001 par value per share (the "Restricted Stock") and received
gross  proceeds  in the  amount of  $32,200.65  from the  issuance  of stock for
services for a total of 62,420 shares of the Company's Restricted Stock.

The April 1998 Funding:

In order to meet the funding need of the Company,  on April 9, 1998, the Company
raised  proceeds  of $300,000  as a bridge  loan in a private  placement  of the
Company's (1) 12.0%  convertible  notes due on the earlier of January 8, 1999 or
at such time as the  Company  receives  the  first  draw  under the  Kingsbridge
Capital  Limited("Kingsbridge")Private  Equity Line of Credit  dated as of March
23, 1998 (the "Notes") and (2) warrants to purchase  shares of Common Stock (the
"Warrants")  to nine (9) investors.  The shares to be issued upon  conversion of
the Notes and exercise of the Warrants shall be Rule 144 restricted  shares. The
maximum number of shares of Common Stock which may be issued by the Company upon
the  conversion  of the Notes  (at a base  conversion  rate of $1.50 per  share,
(subject  to  certain  limitations)  and the  exercise  of the  Warrants  (at an
exercise price of $1.25) is up to 200,000 shares and 210,000  respectively.  The
shares  covered by the  conversion of the Notes and exercise of the Warrants are
entitled to piggyback  registration  rights and were included in Amendment No. 2
to the Form S-1 currently  filed.  The Notes are  convertible  at any time after
issuance,  and the Warrants are  exercisable at any time prior to April 8, 2001.
The  Company  used the gross  proceeds  to finance  further  production  and for
working  capital.  As of August 19, 1998,  none of the Notes have been converted
and none of the Warrants have been exercised.

The First June 1998 Funding

In June 1998,  the  Company  raised  gross  proceeds  of  $200,000  in a private
placement  of warrants to purchase  Common  Stock  (the"June  Warrants")  to two
"accredited"  investors.  The maximum number of shares of Common Stock which may
be issued upon the exercise of the June Warrants (at an exercise  price of $.75)
is up to 1,050,000 shares. The June Warrants may exercise at any time up until 5
PM Eastern Standard Time on the first business day after the fourteen (14) month
period  following  the  date  of the  declaration  of the  effectiveness  of the
Company's registration statement in which the June Warrants are registered.

In the event  that a holder  of the June  Warrants  exercises  for not less than
250,000  (25,000  in the  case  of the  50,000  warrant  holder)  shares  of the
Company's  Common  Stock  within 180 days of June 1, 1998 and  exercises  for at
least an  additional  50,000  (5,000 in the case of the 50,000  warrant  holder)
shares of Common Stock within 360 days of June 1, 1998,  the Company shall issue
of the June Warrants  additional warrants for the purchase of a number of shares
equal to the number of shares  purchased  under the June Warrants within 180 and
360 days of June 1, 1998.  The exercise  price of these  additional  warrants is
equal to $2.00 per share. Such additional  warrants may be exercised at any time
up  until 5 PM  Eastern  Standard  Time on the  first  business  day  after  the
twenty-four  (24) month period  following the date of the  effectiveness  of the
Company's   registration   statement  in  which  the  additional   warrants  are
registered.
                                       16
<PAGE>
In  connection  with the sale of the June  Warrants,  the Company  included  the
shares to be issued upon exercise of the June Warrants in Amendment No. 2 to the
Form S-1 currently  filed.  The Company has committed to register the additional
warrants within ninety (90) days of issuance.  The Company used the net proceeds
of this financing for working  capital.  As of August 19, 1998, none of the June
Warrants have been exercised.

The Second June 1998 Funding

In June 1998,  the  Company  raised  gross  proceeds  of $425,000 in the private
placement of the  Company's  12..0%  subordinated  convertible  notes due on the
earlier of December 1999 or upon the receipt by the Company of debt or equity or
revenue  from the sale of leases or other  property  of $4  million or more (the
"June Notes") and warrants to purchase Common Stock (the "Second June Warrants")
to a limited number of "accredited"  investors.  The maximum number of shares of
Common Stock which may be issued by the Company upon the  conversion of the June
Notes (at a base  conversion  price of $1.00 per share),  subject to  designated
adjustments,  and the exercise of the Second June Warrants (at an exercise price
of $.50 per share for the first two years and $.85 per share  thereafter)  is up
to 425,000 shares and 531,250 shares, respectively.  As of August 19, 1998, none
of the June Notes or the Second June Warrants had been exercised.

The holders of the June Notes may convert  100% of the  principal  amount of the
June Notes at any time after the issuance date. The conversion  rate of the June
Notes is equal to $1.00 per share. The June Notes are subordinated to any senior
debt incurred by the Company.

The holders of the Second June  Warrants  may exercise at any time up until 5 PM
Eastern  Standard Time on June 14, 2002.  The exercise  price of the Second June
Warrants  is equal to $.50 per  share for the first two years and $.85 per share
thereafter,  these  prices are subject to  adjustment.  In the event the Company
does not  register the Second June  Warrants  within six (6) months of issuance,
the  exercise  price for the entire term  through  June 14, 2002 shall remain at
$.50 per share.  Additionally,  the price of the Second  June  Warrants  will be
adjusted  downward  to 50% of market  when the  registration  statement  becomes
effective,  if after 90 days the share price of the Company's Common Stock falls
below $.75 per share for more than five (5)  consecutive  trading  days or seven
(7) out of ten (10) trading  days.  The Second June  Warrants  contain  cashless
exercise and  anti-dilution  provisions  which include,  but are not limited to,
anti-dilution protection against stock or management option issuances below $.50
per share.

In connection with the sale of the June Notes and the Second June Warrants,  the
Company  included  such notes and  warrants in  Amendment  No. 2 to the Form S-1
currently filed. The Company used the net proceeds of this financing for working
capital.  As of August 19, 1998 none of the June Notes have been  converted  and
none of the Second June Warrants have been exercised.

The Third June 1998 Funding

In June 1998,  the Company  raised  gross  proceeds of  $1,250,000  in a private
placement of the Company's 5.5% convertible  notes due in 2000 (the "Second June
Notes") and warrants to purchase Common Stock (the "Third June Warrants") to one
"accredited"  investor.  The  conversion  price is  calculated by formula as the
lower of (i) the  average  closing  bid price for the five (5) days prior to the
closing or (ii) 80% of the average closing bid price for the five (5) days prior
to notice  of intent to  convert.  In the event  that the lower  price  were the
average  closing  bid  price  for the five (5) days  prior to the  closing,  the
maximum number of shares of Common Stock which may be issued by the Company upon
conversion  of the Second  June Notes (at a base price of $.7195) is  1,798,124.
However,  if 80% of the average closing bid price for the five (5) days prior to
the  notice of  intent  to  convert  were the  lower  price,  there is no way to
ascertain  the maximum  number of shares of Common  Stock which may be issued by
the Company upon  conversion of the Second June Notes at this time.  Because the
conversion  rate of the  Second  June  Notes is based in part on future  average
trading  prices of the Common Stock,  the number of shares which may actually be
issued on conversion could differ  significantly.  For example, in the event the
average  closing  bid price  for the five (5) days  prior to notice of intent to
convert  were  $.7195,  80% of such number  would equal a share price of $.5756,
resulting  in a  total  of  2,247,655  shares  of  Common  Stock  issuable  upon
conversion  exclusive  of the  exercise  of any of the Third June  Warrant.  The
maximum number of shares of Common Stock which may be issued by the Company upon
the  exercise of the Third June  Warrants  (at an exercise  price of 120% of the
average  closing bid price for the five (5) days prior to the  closing  which is
equal to $.8634) is 230,000  shares.  As of August 19, 1998,  none of the Second
June  Notes had been  converted  and none of the Third  June  Warrants  had been
exercised.

Under the terms of the Second  June Notes,  the holders  thereof may convert the
original  principal  amount  of the  Second  June  Notes  only to the  extent of
one-third of such amount on and after each of July 23, 1998, August 23, 1998 and
September  23, 1998.  The Second June Notes are  subordinate  to any senior debt
incurred by the Company.

All of the shares to be held by the  Investors  upon  exercise of the Third June
Warrants,  under the terms of the Third June Warrants,  the holders  thereof may
exercise at any time up until 5 PM Eastern  Standard Time on June 23, 2003.  The
exercise price of the Third June Warrants is equal to $.8634 per share.
                                       17
<PAGE>
In  connection  with  the sale of the  Second  June  Notes  and the  Third  June
Warrants,  the Company  entered into a  Registration  Rights  Agreement with the
Selling Shareholders, pursuant to which the Company agreed to register the Third
June 1998  Funding  shares under the  Securities  Act for resale by, and for the
benefit of, such shareholders. The Second June Notes and the Third June Warrants
were included in Amendment No. 2 to the Form S-1  currently  filed.  The Company
used  $1,000,000 of the net proceeds as an additional  concession fee payment in
connection  with its Sao Tome joint  venture.  The  balance was used for working
capital.

The July/August 1998 Funding

In July and August 1998,  the Company  raised gross  proceeds of $1,200,000  and
$275,000  respectively  in a private  placement of up to  $3,000,000  in two (2)
tranches of the Company's 8.0% convertible  notes due in 2000 (the "July Notes")
to a limited number of "accredited"  investors.  The Company anticipates closing
an  additional  tranche  representing  gross  proceeds  of $300,000 on or before
August 18, 1998. The conversion price of the July Notes is calculated by formula
as the  lower of (i) 120% of the  average  closing  bid  price  per share of the
Company's  Common  Stock  for the five (5) days  preceding  the  closing  of the
transaction  or (ii) 75% of the  average  closing  bid  price  per  share of the
Company's  Common  Stock for the five (5) days  preceding  the date  upon  which
notice of conversion is given by the investor to the Company.  In the event that
the lower price were the  average  closing bid price for the five (5) days prior
to the  closing  bid price for the five (5) days  prior to the  closing  of each
tranche, the maximum number of shares of the Common Stock which may be issued by
the Company  upon  conversion  of the July Notes (at a base price of $.74375 and
$.73125  respectively)  is 1,657,928.  However if 75% of the average closing bid
price for the five (5) days prior to the  notice of intent to  convert  were the
lower price, there is no way to ascertain the maximum number of shares of Common
Stock which may be issued by the Company  upon  conversion  of the July Notes at
this time.  Because  the  conversion  rate of the July Notes is based in part on
future average  trading  prices of the Common Stock,  the number of shares which
may actually be issued upon conversion could differ significantly.  For example,
in the event the  average  closing  bid price for the five (5) days prior to the
note of intent to convert were  $.74375,  75% of such number would equal a share
price of  $.55781  resulting  in a total of  2,644,257  shares of  Common  Stock
issuable  upon  conversion  exclusive  of the  exercise of any of the  warrants.
Warrants  were issued to the  placement  agent at the close of each tranche (the
"July  Warrants").  The  maximum  number of shares of Common  Stock which may be
issued by the Company  upon the  exercise of the July  Warrants  (at an exercise
price of $.74375 and $.73125  respectively) is 132,750 shares.  As of August 19,
1998,  none of the July Notes had been  converted  and none of the July Warrants
had been exercised.

Under the terms of the July Notes,  the holders thereof may convert the original
principal  amount of the notes only to the extent of one-third of such amount on
and after each thirty (3) day period following the issuance date. The July Notes
are subordinate to any senior debt incurred by the Company.

Under the terms of the July  Warrants,  the holders  thereof may exercise at any
time up until 5 PM  Eastern  Standard  Time on July 30,  2003 and August 5, 1998
respectively.  The exercise  price of the July Warrants are equal to $.74375 and
$.73125.

In connection with the sale of the July Notes and the July Warrants, the Company
entered into a  Registration  Rights  Agreement  with the Selling  Shareholders,
pursuant to which the Company  agreed to register the July 1998  Funding  shares
under  the  Securities  Act  for  resale  by,  and  for  the  benefit  of,  such
shareholders.  The  July  Notes  and the July  Warrants  were  not  included  in
Amendment No. 2 to the Form S-1 currently  filed. The Company used $1,000,000 of
the net proceeds as an additional  concession fee payment in connection with its
Sao Tome joint venture. The balance was used for working capital.

Operations

During  the third  quarter  1998,  the  Company  focused  on the  funding of the
additional  concession fee due to DRSTP. A substantial  portion of the financing
arranged  during this quarter was paid over as part of this concession fee. ERHC
continues to believe that the Sao Tome Project  needs to be the primary focus of
its  activities due to the extensive  interest and financial  commitments of the
major exploration and production companies in the Gulf of Guinea.

In April, 1998, the Government of Sao Tome granted approval to the joint venture
to proceed with the preparation and sale of leases of its oil concession rights,
which sales are expected to occur in early 1999.

On April 20, 1998,  the government of DRSTP and ERHC filed the two hundred (200)
mile exclusive  economic zone coordinates  with the United Nations.  This is the
last step necessary to establish the exclusive  economic zone for  international
recognition.

In June  1998,  the  Company  and Sao Tome  signed a letter of intent to award a
contract  to  Schlumberger  Geco-Prakla  to perform a marine  seismic  survey in
anticipation  of the  license  round to be held in Sao  Tome,  and to act as the
technical   advisor  and   coordinator  of  such  license  round.   Schlumberger
Geco-Prakla  is a seismic data service  company  located in Great  Britain.  The
exact  number  and size of the  lease  blocks  to be  offered  have not yet been
determined.  The Company  intends to run the survey and acquire the seismic data
in late 1998 in order to proceed with the  licensing  round  commencing in early
1999.

In July 1998,  the  Company  closed and formed the joint  venture  national  oil
company with DRSTP.  This oil company is called the Sao Tome  Principe  National
Petroleum Company S.A. ("STPETRO").  STPETRO is owned fifty one percent (51%) by
DRSTP and forty nine percent (49$) by ERHC. In additional, ERHC has been granted
under  the  original  agreement  with  the  government  a long  term  management
arrangement of STPETRO.  On July 9, 1998, the Ministry of Cabinets and the Prime
Minister executed the STPETRO formation documents and they were promulgated into
law by the President.

During this quarter,  the Company put back on line five (5) additional  wells at
the Wichita Falls fields located in North Texas.  These wells,  and the thirteen
(13) which were previously opened, are currently producing  approximately twenty
(20) barrels a day in total.  ERHC has determined  that with oil prices down, it
is not economically  feasible at this time to continue with the redevelopment of
this field or to rework the wells for increased production.  At such time as oil
prices reach $15 to $18 per barrel, the Company will reconsider its position.

At the Nueces River  Project,  the Company is currently  meeting with  potential
farm-out  partners to work the project.  ERHC believes  Nueces River still holds
tremendous  development  potential;  however,  until  such  time as the  Company
secures long term  funding,  of which there can be no  assurance,  it intends to
look for alternative methods to develop this project.

At the Uinta  Project,  ERHC continues to currently  operate four (4) wells.  At
such time as  additional  funding is  available,  the Company  intends to rework
additional wells.

During the third quarter 1998, the Company awaited  additional  financing and an
increase in oil prices in order to be able to move  forward  with the rework and
development of the MIII project at the Uintah and Ouray Reservation, Utah.

In October 1997,  the Company  received a letter of intent to secure $50 million
in debt financing  from Dirks & Company of New York.  This  transaction  was not
brought to fruition for a number of reasons,  but  principally  because  certain
parties  employed by such firm who would have been  primarily  involved with the
placement of this offering,  left the firm.  After several months,  such parties
became  employed by Security  Capital  Trading,  Inc.  During the second quarter
1998, the Company  renegotiated  this  transaction and on May 7, 1998,  Security
Capital  Trading Inc.  issued a letter of intent in connection with the proposed
offering of $50 million of public debt. This offering is conditioned upon filing
of a Registration Statement on Form S-1 covering the proposed debt offering. The
Company  believes  that  until  such time as its  current  Form S-1,  as amended
becomes  effective,  that it is not in a  position  to file  another  Form  S-1.
Accordingly  the Company  intends to proceed with the Security  Capital  Trading
Inc. debt offering  immediately upon the  effectiveness of its current Form S-1,
as amended.

On May 7, 1998,  Security Capital Trading Inc. also issued a letter of intent to
act as the placement  agent for the private  placement of convertible  preferred
stock of the Company(the "Preferred Stock"). The offer is for the placement of a
minimum of $2,000,000  and a maximum of $5,000,000  at an  anticipated  offering
price per share of  Preferred  Stock of $10.00.  This  Preferred  Stock shall be
offered to accredited  investors  pursuant to Regulation D under the  Securities
Act of 1933 in units of  $50,000.  Each share of  Preferred  Stock  shall have a
liquidation value of $10.00 and shall be convertible into shares of Common Stock
at a rate which is mutually  acceptable to Security Capital Trading Inc. and the
Company. The Company intends to proceed with this offering.

The following  discussion  should be read in conjunction  with the  Consolidated
Financial  Statements  and  Notes  thereto  referred  to in "Item  1.  Financial
Statements.

RESULTS OF OPERATIONS

During  the third  quarter  of fiscal  1998 the  Company  incurred a net loss of
$2,781,000,  compared to a net loss of $1,399,000 in the third quarter of fiscal
1997. In the third  quarter of fiscal 1998 a total of $270,000 was accrued,  but
not paid in cash, as compensation to three officers of the Company. Depreciation
and  amortization  totaled $133,000 in the third quarter of fiscal 1998 compared
to $72,000 in the third quarter of fiscal 1997.  Depletion expense was $1,000 in
the third  quarter of fiscal 1998  compared  to $0 the prior year.  The net cash
operating  loss  of the  Company  for the  third  quarter  of  fiscal  1998  was
$1,498,000 compared to $134,000 for the third quarter of fiscal 1997.

Officers   compensation,   professional  fees,   travel,   consultant  fees  and
miscellaneous  expense for the three months ended June 30, 1998  compared to the
three months ended June 30, 1997 increased  dramatically because the Company had
not been funded at that time and only began its operations by December 31, 1996.
Professional  fees included  legal,  audit and petroleum  engineering  and other
engineering costs.

The Company had  revenues of  $100,000 in third  quarter of fiscal  1998,  after
adjustments for  misclassifications  and overaccruals made in error, compared to
$84,000 in the third quarter of fiscal 1997.

CAPITAL EXPENDITURES

When the Company  entered into the joint venture  agreement in May 1997 with the
DRSTP, the Company was required to pay a $5,000,000  concession fee to the DRSTP
government.   In  September   1997,   the  Company   received  a  Memorandum  of
Understanding  from the DRSTP  government  which  allows the Company to pay this
concession  fee within  five days after the DRSTP  files the  relevant  official
maritime claims maps with the United Nations and the Gulf of Guinea  Commission.
In December 1997 the Company paid $2,000,000 of this concession fee to the DRSTP
from the proceeds of a convertible note offering.

On April 15,  1998,  the  Company  agreed to enter into a joint  venture  with a
privately held Delaware corporation,  AMCO Montenegro,  Inc. and its related ABC
Group of companies  ("AMCO") to construct  and operate an  "Off-Shore  Logistics
Center" for the oil  industry in the Gulf of Guinea,  on the Island of Sao Tome.
The Company is in the process of finalizing the contracts with AMCO.

This Off-Shore Logistics Center will include a dry dock facility.  Currently the
oil industry in the area  utilizes a dry dock in Cape Town,  South  Africa.  The
location of a dry dock  facility on San Tome its expected to be a great  benefit
to the industry, including the Company's activities, as it is expected to reduce
the  down  time by a  minimum  of four  (4)  days  due to Sao  Tome's  strategic
location.

AMCO and its related ABC Group of companies,  including  A.B.C.  AeroEngineering
Ltd. have designed,  developed and constructed  civilian and military  airports,
airport  refueling  and  re-fueling   stations,   road  construction,   military
facilities,  hospitals, healthcare facilities, business and warehouse facilities
and various other industrial  support  structures.  The Company has entered into
preliminary  discussions with marine transport and air support companies for the
use of this logistics center. AMCO is responsible for funding this project.

The Off-Shore  Logistics  Center will be an on-shore based operation on Sao Tome
which can service  off-shore  drilling  rigs and act as the central  depository,
storage and service area for the drilling and oil  production  in the area.  The
facility will be designed to provide  services and supplies to support  drilling
off-shore wells,  including,  pipe, casing and other tubular goods, fuel, water,
drilling mud facilities and supplies,  rental tools and a dry dock facility.  In
addition,  it  is  intended  to  provide  helicopter,   fixed  wing  and  marine
facilities,  such as crew and  transport  boats and will  encompass  housing and
business facilities for oil company personnel.

In April 22,  1998,  Jugobanks  AD  Podgorica  of  Montenegro  agreed to finance
$50,000,000 for the construction the Off-Shore Logistics Center in Sao Tome. The
Company and AMCO are working with the bank on the final loan documentation.

On July 2, 1998,  the Company paid an additional  payment on the  concession fee
due to DRSTP in the amount of  $1,000,000  out of the proceeds of the Third June
1998 Financing and on July 31,1998,  the Company made another additional payment
in the amount of $1,000,000 out of the proceeds of the July/August 1998 Funding.

On September 29, 1997, the Company  entered into an agreement to acquire 22 oil,
gas and mineral leases located in Uintah and Duchesne Counties,  Utah from three
joint  owners.  The purchase  agreement  was closed on October 8, 1997, at which
time the Company received the lease assignment. The terms of the acquisition are
for the Company to pay $250,000 in cash,  issue 250,000  shares of the Company's
common  stock,  valued  at  $2,000,000,  at each of the  following  four  dates:
closing;  December 30, 1997;  March 30, 1998 and June 30, 1998. The Company also
was  required  to  guarantee  that  the bid  price  on the  date  the  Rule  144
restrictions  lapse  will be no less  than  $2.00 per  share or the  Company  is
required to either issue additional  shares or to pay the difference in cash, at
the Company's option. The Company also granted the sellers a 4% gross production
receipts royalty to a maximum of $677,000.  The Company is currently  evaluating
the  existing  reserve  reports  and  underlying  data on these  leases  and has
contracted another independent appraiser to complete new reserve reports for its
use. The 250,000 shares of the Company's  Common Stock due on June 30, 1998 were
issued in accordance with the agreement.

In  October  1997,  the  Company  entered  into an  agreement  to  acquire a 3/8
undivided  interest  in a natural gas well that had been  plugged and  abandoned
approximately  10 years ago.  This  agreement  requires  the  Company to pay the
seller  $150,000  and 50,000  shares of the  Company's  common  stock  valued at
$148,750,  as well as to pay the Company's  proportionate  share of the costs to
reenter  this well.  The  Company is also  required  to carry the  seller's  1/8
proportionate share of the reentry costs until the well is producing.

The seller also owns an  undivided  50% interest in the oil and gas lease on the
49,019 acres of land  contiguous to the initial well.  The agreement  allows the
Company  to  acquire a 3/8  undivided  interest  in this  lease by paying to the
seller  approximately  $343,000 each April for four years.  The Company received
the initial  lease  assignment  on December 1, 1997.  The Company  continues  to
evaluate the existing  reserve  reports and underlying  data on these leases and
awaits  another  independent  appraiser to complete new reserve  reports for its
use.

To further penetrate the environmental remediation services market in Louisiana,
in February  1998,  the Company  acquired a 70% equity  interest in Ven Virotek,
Inc., a Louisiana corporation ("Virotek"), from its sole shareholder,  Recycling
Remedies,  Inc.  Virotek owns and operates a NORM solid waste  disposal  site in
Houma, Louisiana and holds permits from Louisiana  environmental  authorities to
dispose of salt water brine and naturally occurring waste products. For the year
ended  December 31, 1997,  Virotek had revenues,  net income and total assets of
approximately  $658,000,  $332,000,  and $1,035,000,  respectively.  The Company
acquired  its interest in Virotek in  consideration  for $15,000 in cash and the
assumption of a $300,000 bank note.

In March 1998, Virotek obtained two contracts from the U.S. Department of Energy
to dispose of salt water brine from the strategic  petroleum  reserve located in
Houma, Louisiana. Under the contracts, it is contemplated initially that a total
of 475,000 barrels of brine will be shipped to Virotek for disposal, and Virotek
will  receive  $1.00  per  barrel  for  its  services.  There  were  no  further
developments with Virotek during the third quarter 1998.

RESERVES AND PRICING

Oil and natural  gas prices  fluctuate  throughout  the year.  Generally  higher
natural  gas  prices  prevail  during  the winter  months of  September  through
February.  A significant  decline in prices would have a material  effect on the
measure of future net cash flows which,  in turn,  could impact the value of the
Company's oil and gas properties.

The Company's  drilling and  acquisition  activities  have increased its reserve
base and its productive capacity and, therefore,  its potential cash flow. Lower
gas prices may adversely  affect cash flow.  The Company  intends to continue to
acquire and develop oil and gas  properties in its areas of activity as dictated
by market conditions and financial ability.  The Company retains  flexibility to
participate  in oil and gas  activities at a level that is supported by its cash
flow and financial  ability.  Management  believes that the Company's  borrowing
capacities  and cash  flow are  sufficient  to fund  its  currently  anticipated
activities.  The Company  intends to continue to use financial  leverage to fund
its  operations  as  investment  opportunities  become  available  on terms that
management believes warrant investment of the Company's capital resources.

The Company is currently  evaluating the existing reserve reports and underlying
data on all leases and has  contracted  with  another  independent  appraiser to
complete new reserve reports.

The Company's  non-producing proved reserves are largely "behind-pipe" in fields
which it operates. Undeveloped proved reserves are predominantly infill drilling
locations and secondary recovery projects.
                                       21
<PAGE>
The reserve data set forth in this Form 10-Q represent only  estimates.  Reserve
engineering is a subjective process of estimating  underground  accumulations of
oil and gas that  cannot be  measured in an exact  manner.  The  accuracy of any
reserve  estimate  is a  function  of  the  quality  of  available  data  and of
engineering and geological  interpretation and judgment. As a result,  estimates
of different engineers often vary. In addition, results of drilling, testing and
production  subsequent  to the date of an estimate may justify  revision of such
estimate. Accordingly, reserve estimates often differ from the quantities of oil
and  natural  gas that are  ultimately  recovered.  the  meaningfulness  of such
estimates is highly  dependent upon the accuracy of the  assumptions  upon which
they were based.

Forward-Looking Statements

This Form 10-Q  includes  "forward-looking  statements"  within  the  meaning of
Section 27A of the  Securities  Act of 1933, as amended,  and Section 21E of the
Securities  Exchange  Act of  1934,  as  amended.  All  statements,  other  than
statements of historical  facts,  included or  incorporated by reference in this
Form 10-Q which address  activities,  events or  developments  which the Company
expects or anticipates will or may occur in the future, including such things as
future capital expenditures (including the amount and nature thereof),  wells to
be  drilled  or  reworked,  oil and gas  prices  and  demand,  exploitation  and
exploration  prospects,  development and infill potential,  drilling  prospects,
expansion and other  development  trends of the oil and gas  industry,  business
strategy,  production  of oil and gas  reserves,  expansion  and  growth  of the
Company's  business and operations,  and other such matters are  forward-looking
statements.  These statements are based on certain assumptions and analyses made
by the  Company in light of its  experience  and its  perception  of  historical
trends,  current  conditions and expected  future  developments as well as other
factors it believes  are  appropriate  in the  circumstances.  However,  whether
actual results and developments will conform with the Company's expectations and
predictions  is  subject  to  a  number  of  risks  and  uncertainties,  general
economic,market  or business  conditions;  the business  opportunities  (or lack
thereof) that may be presented to and pursued by the Company; changes in laws or
regulation;  and other  factors,  most of which are  beyond  the  control of the
Company.  Consequently all of the  forward-looking  statements made in this Form
10-Q are qualified by these cautionary  statements and there can be no assurance
that the actual  results or  developments  anticipated  by the  Company  will be
realized or, even if  substantially  realized,  that they will have the expected
consequences to or effects on the Company or its business or operations.

The April 1998 Funding:

In order to meet the funding need of the Company,  on April 9, 1998, the Company
raised  proceeds  of $300,000  as a bridge  loan in a private  placement  of the
Company's (1) 12.0%  convertible  notes due on the earlier of January 8, 1998 or
at such time as the  Company  receives  the  first  draw  under the  Kingsbridge
Private  Equity Line of Credit dated as of March 23, 1998 (the  "Notes") and (2)
warrants  to  purchase  shares  of Common  Stock  (the  "Warrants")  to nine (9)
"accredited investors". The shares to be issued upon conversion of the Notes and
exercise of the Warrants shall be Rule 144 restricted shares. The maximum number
of shares of Common Stock which may be issued by the Company upon the conversion
of the Notes (at a base conversion rate of $1.50 per share,  (subject to certain
limitations) and the exercise of the Warrants (at an exercise price of $1.25) is
up to  200,000  shares  and  210,000  respectively.  The  shares  covered by the
conversion  of the Notes and  exercise of the Warrants are entitled to piggyback
registration  rights  and  were  included  in  Amendment  No.  2 to the Form S-1
currently filed.  The Notes are convertible at any time after issuance,  and the
Warrants are  exercisable  at any time prior to April 8, 2001.  The Company used
the gross proceeds to finance further production and for working capital.  As of
August 19, 1998,  none of the Notes have been converted and none of the Warrants
have been exercised. No underwriter was used in connection with this funding.

The First June 1998 Funding

In June 1998,  the  Company  raised  gross  proceeds  of  $200,000  in a private
placement  of warrants to purchase  Common  Stock  (the"June  Warrants")  to two
"accredited"  investors.  The maximum number of shares of Common Stock which may
be issued upon the exercise of the June Warrants (at an exercise  price of $.75)
is up to 1,050,000 shares. The June Warrants may exercise at any time up until 5
PM Eastern Standard Time on the first business day after the fourteen (14) month
period  following  the  date  of the  declaration  of the  effectiveness  of the
Company's registration statement in which the June Warrants are registered.

In the event  that a holder  of the June  Warrants  exercises  for not less than
250,000  (25,000  in the  case  of the  50,000  warrant  holder)  shares  of the
Company's  Common  Stock  within 180 days of June 1, 1998 and  exercises  for at
least an  additional  50,000  (5,000 in the case of the 50,000  warrant  holder)
shares of Common Stock within 360 days of June 1, 1998,  the Company shall issue
of the June Warrants  additional warrants for the purchase of a number of shares
equal to the number of shares  purchased  under the June Warrants within 180 and
360 days of June 1, 1998.  The exercise  price of these  additional  warrants is
equal to $2.00 per share. Such additional  warrants may be exercised at any time
up  until 5 PM  Eastern  Standard  Time on the  first  business  day  after  the
twenty-four  (24) month period  following the date of the  effectiveness  of the
Company's   registration   statement  in  which  the  additional   warrants  are
registered.

In  connection  with the sale of the June  Warrants,  the Company  included  the
shares to be issued upon exercise of the June Warrants in Amendment No. 2 to the
Form S-1 currently  filed.  The Company has committed to register the additional
warrants within ninety (90) days of issuance.  The Company used the net proceeds
of this financing for working  capital.  As of August 19, 1998, none of the June
Warrants have been  exercised.  No underwriter  was used in connection with this
funding.

The Second June 1998 Funding

In June 1998,  the  Company  raised  gross  proceeds  of $425,000 in the private
placement of the  Company's  12..0%  subordinated  convertible  notes due on the
earlier of December 1999 or upon the receipt by the Company of debt or equity or
revenue  from the sale of leases or other  property  of $4  million or more (the
"June Notes") and warrants to purchase Common Stock (the "Second June Warrants")
to a limited number of "accredited"  investors.  The maximum number of shares of
Common Stock which may be issued by the Company upon the  conversion of the June
Notes (at a base  conversion  price of $1.00 per share),  subject to  designated
adjustments,  and the exercise of the Second June Warrants (at an exercise price
of $.50 per share for the first two years and $.85 per share  thereafter)  is up
to 425,000 shares and 531,250 shares, respectively.  As of August 19, 1998, none
of the June Notes or the Second June Warrants had been exercised.

The holders of the June Notes may convert  100% of the  principal  amount of the
June Notes at any time after the issuance date. The conversion  rate of the June
Notes is equal to $1.00 per share. The June Notes are subordinated to any senior
debt incurred by the Company.
                                       23
<PAGE>
The holders of the Second June  Warrants  may exercise at any time up until 5 PM
Eastern  Standard Time on June 14, 2002.  The exercise  price of the Second June
Warrants  is equal to $.50 per  share for the first two years and $.85 per share
thereafter,  these  prices are subject to  adjustment.  In the event the Company
does not  register the Second June  Warrants  within six (6) months of issuance,
the  exercise  price for the entire term  through  June 14, 2002 shall remain at
$.50 per share.  Additionally,  the price of the Second  June  Warrants  will be
adjusted  downward  to 50% of market  when the  registration  statement  becomes
effective,  if after 90 days the share price of the Company's Common Stock falls
below $.75 per share for more than five (5)  consecutive  trading  days or seven
(7) out of ten (10) trading  days.  The Second June  Warrants  contain  cashless
exercise and  anti-dilution  provisions  which include,  but are not limited to,
antidilutive  protection against stock or management option issuances below $.50
per share.

In connection with the sale of the June Notes and the Second June Warrants,  the
Company  included  such notes and  warrants in  Amendment  No. 2 to the Form S-1
currently filed. The Company used the net proceeds of this financing for working
capital.  As of August 19, 1998 none of the June Notes have been  converted  and
none of the Second June Warrants have been exercised. No underwriter was used in
connection with this funding.

The Third June 1998 Funding

In June 1998,  the Company  raised  gross  proceeds of  $1,250,000  in a private
placement of the Company's 5.5% convertible  notes due in 2000 (the "Second June
Notes") and warrants to purchase Common Stock (the "Third June Warrants") to one
"accredited  investor".  The  conversion  price is  calculated by formula as the
lower of (i) the  average  closing  bid price for the five (5) days prior to the
closing  or (ii) 80% of the  average  closing  bide  price for the five (5) days
prior to notice of intent to convert. In the event that the lower price were the
average  closing  bid  price  for the five (5) days  prior to the  closing,  the
maximum number of shares of Common Stock which may be issued by the Company upon
conversion  of the Second  June Notes (at a base price of $.7195) is  1,798,124.
However,  if 80% of the average closing bid price for the five (5) days prior to
the  notice of  intent  to  convert  were the  lower  price,  there is no way to
ascertain  the maximum  number of shares of Common  Stock which may be issued by
the Company upon  conversion of the Second June Notes at this time.  Because the
conversion  rate of the  Second  June  Notes is based in part on future  average
trading  prices of the Common Stock,  the number of shares which may actually be
issued on conversion could differ  significantly.  For example, in the event the
average  closing  bid price  for the five (5) days  prior to notice of intent to
convert  were  $.7195,  80% of such number  would equal a share price of $.5756,
resulting  in a  total  of  2,247,655  shares  of  Common  Stock  issuable  upon
conversion  exclusive  of the  exercise  of any of the Third June  Warrant.  The
maximum number of shares of Common Stock which may be issued by the Company upon
the  exercise of the Third June  Warrants  (at an exercise  price of 120% of the
average  closing bid price for the five (5) days prior to the  closing  which is
equal to $.8634) is 230,000  shares.  As of August 19, 1998,  none of the Second
June  Notes had been  converted  and none of the Third  June  Warrants  had been
exercised.

Under the terms of the Second  June Notes,  the holders  thereof may convert the
original  principal  amount  of the  Second  June  Notes  only to the  extent of
one-third of such amount on and after each of July 23, 1998, August 23, 1998 and
September  23, 1998.  The Second June Notes are  subordinate  to any senior debt
incurred by the Company.

All of the shares to be held by the  Investors  upon  exercise of the Third June
Warrants,  under the terms of the Third June Warrants,  the holders  thereof may
exercise at any time up until 5 PM Eastern  Standard Time on June 23, 2003.  The
exercise price of the Third June Warrants is equal to $.8634 per share.

In  connection  with  the sale of the  Second  June  Notes  and the  Third  June
Warrants,  the Company  entered into a  Registration  Rights  Agreement with the
Selling Shareholders, pursuant to which the Company agreed to register the Third
June 1998  Funding  shares under the  Securities  Act for resale by, and for the
benefit of, such shareholders. The Second June Notes and the Third June Warrants
were included in Amendment No. 2 to the Form S-1  currently  filed.  The Company
used  $1,000,000 of the net proceeds as an additional  concession fee payment in
connection  with its Sao Tome joint  venture.  The  balance was used for working
capital.

The firm of Joseph Charles & Associates  which is located at Lenox Center,  3355
Lenox Road, #750, Atlanta, GA 30326 acted as the underwriter of this placement.

The July/August 1998 Funding

In July and August 1998,  the Company  raised gross  proceeds of $1,200,000  and
$275,000  respectively  in a private  placement of up to  $3,000,000  in two (2)
tranches of the Company's 8.0% convertible  notes due in 2000 (the "July Notes")
to a limited number of "accredited"  investors.  The Company anticipates closing
an additional tranche representing gross proceeds of $300,000 on or before April
15, 1998. The conversion price of the July Notes is calculated by formula as the
                                       24
<PAGE>
lower of (i) 120% of the average  closing  bid price per share of the  Company's
Common Stock for the five (5) days  preceding the closing of the  transaction or
(ii) 75% of the  average  closing  bid price per share of the  Company's  Common
Stock for the five (5) days  preceding  the date upon which notice of conversion
is given by the investor to the Company.  In the event that the lower price were
the  average  closing  bid price for the five (5) days prior to the  closing bid
price for the five (5) days prior to the  closing of each  tranche,  the maximum
number of shares of the Common  Stock  which may be issued by the  Company  upon
conversion  of  the  July  Notes  (at  a  base  price  of  $.74375  and  $.73125
respectively) is 1,657,928.  However if 75% of the average closing bid price for
the five (5) days prior to the notice of intent to convert were the lower price,
there is no way to ascertain the maximum  number of shares of Common Stock which
may be issued by the  Company  upon  conversion  of the July Notes at this time.
Because the conversion rate of the July Notes is based in part on future average
trading  prices of the Common Stock,  the number of shares which may actually be
issued upon conversion could differ significantly. For example, in the event the
average  closing  bid price for the five (5) days prior to the note of intent to
convert  were  $.74375,  75% of such number would equal a share price of $.55781
resulting  in a  total  of  2,644,257  shares  of  Common  Stock  issuable  upon
conversion  exclusive  of the  exercise of any of the  warrants.  Warrants  were
issued  to  the  placement  agent  at the  close  of  each  tranche  (the  "July
Warrants").  The maximum number of shares of Common Stock which may be issued by
the Company  upon the  exercise of the July  Warrants  (at an exercise  price of
$.74375 and $.73125 respectively) is 132,750 shares. As of August 19, 1998, none
of the July  Notes had been  converted  and none of the July  Warrants  had been
exercised.

Under the terms of the July Notes,  the holders thereof may convert the original
principal  amount of the notes only to the extent of one-third of such amount on
and after each thirty (3) day period following the issuance date. The July Notes
are subordinate to any senior debt incurred by the Company.

Under the terms of the July  Warrants,  the holders  thereof may exercise at any
time up until 5 PM  Eastern  Standard  Time on July 30,  2003 and August 5, 1998
respectively.  The exercise  price of the July Warrants are equal to $.74375 and
$.73125.

In connection with the sale of the July Notes and the July Warrants, the Company
entered into a  Registration  Rights  Agreement  with the Selling  Shareholders,
pursuant to which the Company  agreed to register the July 1998  Funding  shares
under  the  Securities  Act  for  resale  by,  and  for  the  benefit  of,  such
shareholders.  The  July  Notes  and the July  Warrants  were  not  included  in
Amendment No. 2 to the Form S-1 currently  filed. The Company used $1,000,000 of
the net proceeds as an additional  concession fee payment in connection with its
Sao Tome joint venture. The balance was used for working capital.

The firm of J.P. Carey  Securities,  Inc. which is located at Atlanta  Financial
Center,  East Tower, 3343 Peachtree Road, Suite 500, Atlanta,  GA 30326 acted as
the underwriter of this funding.

Exemption from Registration Claimed

While no offering  memorandum was used in connection  with the stock offering or
any of the fundings in this third quarter 1998, the business plan of the Company
as set forth in the Form S-1 filed on  January 8, 1998 with the  Securities  and
Exchange  Commission and in subsequent  amendments  thereto filed April 15, 1998
and July 24, 1998 was disclosed to each  prospective  investor.  The  additional
facts relied upon by the Company to make the federal exemption available include
the following  (1) as a reporting  company,  the Company made  available to each
potential investor the type of information  required by Rule 502(b)(2)(ii);  (2)
the Company made available to each  purchaser at a reasonable  time prior to his
purchase an  opportunity  to ask questions and receive  answers  concerning  the
terms and  conditions of the offering or to obtain any  additional  information;
(3) no general  solicitation  or  advertising  was  conducted  by the Company in
connection  with  the  offering  of any of the  shares;  (4)  the  Company  made
reasonable inquiry to determine that the purchasers were not underwriters within
the meaning of Section 2(11) of the Act; (4) as to each purchaser who was not an
accredited  investor,  the  Company  determined  that  either  alone or with his
purchaser  representative,  had such  knowledge and  experience in financial and
business  matters that the purchaser  was capable of  evaluating  the merits and
risks of the prospective  investment,  or the Company  reasonably  believed that
prior to making such sale, that such purchaser came within this description.

Item 3. Defaults Upon Senior Securities.

None. A requirement of funding provided to the Company on November 15, 1997 from
Avalon  Research  Group,  Inc.  ("Avalon")  was that the Company  would file its
registration  statement within forty-five (45) days of the funding. The Form S-1
was filed by the  Company  on  January  8,  1998;  however,  this  eight (8) day
lateness was waived by the Avalon investors. In addition, the Company had agreed
to use its best efforts to have its registration  statement  declared  effective
within one hundred  twenty  (120) days of the  November  15, 1997  closing.  The
Company  believes  that it has used its best  efforts  to have its  registration
declared  effective.  The Avalon  registration rights agreement required that in
the event that the  registration  statement was not effective within one hundred
twenty (120) days,  that the Company would pay as  liquidated  damages an amount
equal to three percent (3%) of the aggregate amount of the notes per month. As a
result of the delay in declaring the Form S-1 as amended effective,  the Company
owes the Avalon investors  $136,500 for a part of the month of March and for the
full months of April,  May and June 1998 and a additional  amount of $39,000 for
the month of July 1998.  These  outstanding  amounts do not  represent a default
under the convertible senior  subordinated notes issued to the Avalon investors;
however  do  represent  a debt  due by  the  Company  and a  default  under  the
Collateral  Assignment Security Agreement under which the Company granted to the
Avalon  investors  a security  interest  in the  rights to  certain  oil and gas
reserves  located in Duchesne and Uintah  Counties,  Utah  pursuant to which the
Company and its subsidiary currently enjoys the right to exploit certain oil and
gas reserves thereon.

EXHIBIT 4.3

THIS  WARRANT AND THE SHARES OF COMMON  STOCK  PURCHASABLE  HEREUNDER  HAVE BEEN
ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED,  OR APPLICABLE  STATE LAWS. SUCH SECURITIES MAY NOT BE SOLD OR
TRANSFERRED  UNLESS THE  REGISTRATION  PROVISIONS OF SAID ACT AND LAWS HAVE BEEN
COMPLIED WITH OR UNLESS ENVIRONMENTAL  REMEDIATION HOLDING CORP. HAS RECEIVED AN
OPINION OF COUNSEL ACCEPTABLE TO IT THAT SUCH REGISTRATION IS NOT REQUIRED.

                                     WARRANT

                   To Purchase 500,000 Shares of Common Stock
                                       of
                     ENVIRONMENTAL REMEDIATION HOLDING CORP.

                               Dated June 1, 1998

In consideration  of the amount of One Hundred Thousand Dollars  ($100,000) paid
by  __________________,  to Environmental  Remediation  Holding  Corporation,  a
Colorado  corporation  ("ERHC"),  ______________________  or registered  assigns
("Holder") is entitled to purchase from ERHC, at the Exercise Price of $0.75 per
share,  up to Five  Hundred  Thousand  (500,000)  shares of ERHC  Common  Stock,
$0.0001 par value per share ("Common Stock"), subject to adjustment and upon the
terms and  conditions  hereinafter  provided.  This  Warrant may be exercised in
whole or in part, but in increments of at least Fifty Thousand  (50,000) shares,
at any time or from time to time  after  June 1,  1998 and  prior to 5:00  p.m.,
Eastern  Standard  Time, on the first Business Day after the fourteen (14) month
period  following  the  date  of the  declaration  of  effectiveness  of  ERHC's
registration  statement  to be filed on Form S-1 or S-3 (or their  then  current
equivalents)  with the  Securities and Exchange  Commission  ("SEC") in order to
register the shares of Common Stock  underlying this Warrant (the  "Registration
Statement"), as further described in Section 1.6 below.

Certain terms used in this Warrant are defined in Article IV.
<PAGE>
                                    ARTICLE I
               EXERCISE OF WARRANT; REGISTRATION OF WARRANT SHARES

1.1.  Method of  Exercise.  To exercise  this  Warrant in whole or in part,  the
Holder shall deliver,  on any Business Day, to ERHC at its principal offices (a)
this Warrant,  (b) a written notice in the form attached  hereto as Exhibit A of
such Holder's election to exercise this Warrant,  which notice shall specify the
number of shares of Common Stock to be purchased  (which shall be a whole number
of shares if for less than all the shares then issuable hereunder, and shall not
be for less than Fifty Thousand (50,000 shares)), the denominations of the share
certificate  or  certificates  desired  and the  name or  names  in  which  such
certificates  are to be  registered,  and (c) payment of the aggregate  Exercise
Price with respect to such shares.

Such payment of the aggregate  Exercise  Price may be made, at the option of the
Holder,  by any  combination of (1) cash,  check or wire transfer in immediately
available  funds to ERHC in an amount equal to the product of the Exercise Price
multiplied  by the number of shares of Common  Stock  being  purchased  with the
proceeds of such cash,  check or wire  transfer,  or (2) a written notice to the
Company that the Holder is exercising  the Warrants (or a portion  thereof) on a
"cashless  net  exercise"  basis,  under  which ERHC shall issue and deliver the
number of Warrant Shares  purchased less the number of shares of Common Stock as
shall at the time of such exercise have an aggregate  Fair Market Value equal to
the  applicable  aggregate  Exercise  Price (and the  shares of Common  Stock so
withheld shall no longer be issuable  under this  Warrant).  In the event Holder
exercises  this  Warrant in whole or in part on a cashless  net basis,  the Fair
Market Value of the Common Stock shall  established  as of the close of business
on the  Business  Day  preceding  the date that  Holder's  notice of election to
exercise on a cashless net basis is delivered to ERHC.

ERHC shall,  as promptly as  practicable  and in any event within five  Business
Days after  receipt of such notice and payment,  execute and deliver or cause to
be executed and  delivered,  in accordance  with such notice,  a certificate  or
certificates  representing  the  aggregate  number of  shares  of  Common  Stock
specified in said notice.  The share  certificate or  certificates  so delivered
shall be in such  denominations as may be specified in such notice, and shall be
issued  in the  name of the  Holder  or such  other  name or  names  as shall be
designated in such notice.  This Warrant shall be deemed to have been  exercised
and such certificate or certificates shall be deemed to have
<PAGE>
been  issued,  and such  Holder or any other  Person so  designated  to be named
therein  shall be deemed for all  purposes  to have become a holder of record of
shares,  as of the date the  aforementioned  notice and  payment is  received by
ERHC. If this Warrant shall have been exercised only in part, ERHC shall, at the
time of delivery of such  certificate or  certificates,  deliver to the Holder a
new Warrant  evidencing  the rights to purchase the  remaining  shares of Common
Stock called for by this Warrant,  which new Warrant shall in all other respects
be identical  with this Warrant,  or, at the request of the Holder,  appropriate
notation may be made on this Warrant which shall then be returned to the Holder.
ERHC shall pay all expenses,  taxes and other charges payable in connection with
the preparation,  issuance and delivery of share  certificates and new Warrants,
except that, if share certificates or new Warrants shall be registered in a name
or names other than the name of the Holder, funds sufficient to pay all transfer
taxes  payable as a result of such  transfer  shall be paid by the Holder at the
time of delivery  of the  aforementioned  notice of  exercise  or promptly  upon
receipt of a written request of ERHC for payment.

1.2.  Shares to be Fully  Paid and  Nonassessable.  All  shares of Common  Stock
issued upon the exercise of this Warrant shall be validly issued, fully paid and
nonassessable.

1.3. No Fractional  Shares Required to be Issued.  ERHC shall not be required to
issue fractions of shares of Common Stock upon exercise of this Warrant.

1.4.  Reservation.  ERHC has duly reserved and will keep  available for issuance
upon  exercise of the Warrants the total  number of Warrant  Shares  deliverable
from time to time upon exercise of all Warrants from time to time outstanding.

1.5. Expiration Date of Warrant. This Warrant shall expire at 5:00 p.m., Eastern
Standard  Time,  on the first  Business  Day (the  "Expiration  Date") after the
fourteen  (14)  month  period  following  the  date  of  declaration  by the SEC
("Effective  Date") of the  effectiveness  of the  Registration  Statement to be
filed on Form S-1 or S-3 (or their  then  current  equivalents)  with the SEC in
order to register the shares of Common Stock underlying this Warrant.

1.6  Registration  of Warrant  Shares.  Within  ninety (90) days  following  the
issuance of this Warrant, ERHC will file with the SEC the Registration Statement
on Form S-1 or Form S-3 (or their then
<PAGE>
equivalents)  to register  under the  Securities  Act the Common Stock issued or
issuable  pursuant to the exercise of this  Warrant.  ERHC will  thereafter,  as
expeditiously as possible, (i) effect the qualification and registration of such
shares of Common Stock under the Securities Act and state  securities  laws, and
(ii)  maintain  the  effectiveness  for  up to  fourteen  (14)  months  of  such
Registration  Statement.  Holder agrees to provide ERHC, at ERHC's request, with
such  information  about Holder as it may reasonably  request in order to effect
the registration under the Registration  Statement.  ERHC will from time to time
amend or supplement  such  Registration  Statement and the prospectus  contained
therein to the extent  necessary  to comply  with the  Securities  Act and state
securities  laws. ERHC will provide Holder with as many copies of the prospectus
contained in the Registration  Statement as Holder may reasonably request.  ERHC
shall  furnish to Holder at  Holder's  request  an opinion of counsel  for ERHC,
dated the effective date of the Registration Statement,  and a "comfort" letter,
signed by ERHC's  independent  accountants  who have  examined  and  reported on
ERHC's financial statements included in the Registration Statement, in each case
addressing such matters as are customarily covered in such opinions.  ERHC shall
bear all costs and  expenses  of the  Registration  Statement  and  registration
procedures described in this Section 1.6.

1.7 Rule 144. ERHC  covenants and agrees that it will file on a timely basis any
and all  reports  required  to be filed by it under the  Securities  Act and the
Securities  Exchange Act of 1934, as amended, so as to enable Holder to sell the
Warrant  Shares  without  registration  under  the  Securities  Act  within  the
limitations  of the exemptions  provided by Rule 144 of the  Securities  Act, as
such Rule may be amended  from time to time (or any similar  rule adopted by the
SEC).

                                   ARTICLE II
                 TRANSFER, EXCHANGE AND REPLACEMENT OF WARRANTS

2.1. Ownership of Warrant. ERHC may deem and treat the person in whose name this
Warrant  is  registered  as the  holder and owner  hereof  (notwithstanding  any
notations of ownership or writing hereon made by any person other than ERHC) for
all purposes and shall not be affected by any notice to the contrary,  until due
presentment  of this  Warrant for  registration  of transfer as provided in this
Article II.

2.2.     Transfer of Warrant.  The Holder may sell, assign, transfer, give
away or otherwise dispose of (any of the foregoing, a "Transfer") in
<PAGE>
whole or in part its Warrants or Warrants  Shares to any Person,  provided  that
Holder  shall first give ERHC written  notice of such  intended  Transfer.  ERHC
agrees to  maintain  at its  principal  offices  books for the  registration  of
transfers of the Warrants, and transfer of this Warrant and all rights hereunder
shall be registered,  in whole or in part, on such books, upon surrender of this
Warrant  to ERHC,  together  with a  written  assignment  of this  Warrant  duly
executed by the Holder or its duly  authorized  agent or attorney,  with (if the
Holder is a natural person) signatures  guaranteed by a bank or trust company or
a broker  or dealer  registered  with the  National  Association  of  Securities
Dealers,  Inc., and funds sufficient to pay any transfer taxes payable upon such
transfer.  Upon surrender and, if required, such payment, ERHC shall execute and
deliver a new Warrant or Warrants in the name of the assignee or  assignees  and
in the  denominations  specified in the instrument of assignment (which shall be
whole  numbers of shares  only) and shall  issue to the  assignor a new  Warrant
evidencing  the portion of this Warrant not so assigned,  and this Warrant shall
promptly be canceled.

2.3.  Division  or  Combination  of  Warrants.  This  Warrant  may be divided or
combined  with other  Warrants  upon  presentment  hereof and of any  Warrant or
Warrants  with which this  Warrant is to be  combined,  together  with a written
notice specifying the names and  denominations  (which shall be whole numbers of
shares  only) in which the new Warrant or Warrants  are to be issued,  signed by
the holders hereof and thereof or their  respective  duly  authorized  agents or
attorneys.  ERHC shall execute and deliver a new Warrant or Warrants in exchange
for the Warrant or Warrants  to be divided or combined in  accordance  with such
notice.

2.4. Loss, Theft, Destruction of Warrant Certificates.  Upon receipt of evidence
satisfactory  to ERHC of the ownership of and the loss,  theft,  destruction  or
mutilation  of any  Warrant  and,  in  the  case  of any  such  loss,  theft  or
destruction,  upon receipt of indemnity or security  satisfactory to ERHC or, in
the  case of any  such  mutilation,  upon  surrender  and  cancellation  of such
Warrant, ERHC will make and deliver, in lieu of such lost, stolen,  destroyed or
mutilated  Warrant,  a new Warrant of like tenor and  representing  the right to
purchase the same aggregate number of shares of Common Stock.

                                   ARTICLE III
                             ANTIDILUTION PROVISIONS

3.1. Adjustment Generally. The Exercise Price and the number of shares of Common
Stock (or other  securities or property)  issuable upon exercise of this Warrant
shall be subject to adjustment  from time to time upon the occurrence of certain
events as provided in this Article III; provided that  notwithstanding  anything
to the contrary  contained herein, the Exercise Price shall not be less than the
current par value of the Common Stock.

3.2. Common Stock  Reorganization.  If ERHC after the original  issuance date of
the Warrants  shall  subdivide  its  outstanding  shares of Common Stock (or any
class thereof) into a greater number of shares or  consolidate  its  outstanding
shares of Common Stock (or any class  thereof)  into a smaller  number of shares
(any such event  being  called a "Common  Stock  Reorganization"),  then (a) the
Exercise Price shall be adjusted, effective immediately after the effective date
of such Common Stock  Reorganization,  to a price  determined by multiplying the
Exercise Price in effect immediately prior to such effective date by a fraction,
the numerator of which shall be the number of shares of Common Stock outstanding
(on a Fully Diluted  Basis) on such  effective date before giving effect to such
Common Stock Reorganization, and the denominator of which shall be the number of
shares of Common  Stock  outstanding  (on a Fully  Diluted  Basis)  after giving
effect to such  Common  Stock  Reorganization,  and (b) the  number of shares of
Common  Stock  subject  to  purchase  upon  exercise  of this  Warrant  shall be
adjusted,  effective at such time,  to a number  determined by  multiplying  the
number of shares of Common  Stock  subject to purchase  immediately  before such
Common Stock  Reorganization  by a fraction the  numerator of which shall be the
number of shares of Common Stock  outstanding  (on a Fully Diluted  Basis) after
giving effect to such Common Stock Reorganization,  and the denominator of which
shall be the number of shares of Common Stock  outstanding  (on a Fully  Diluted
Basis) immediately before such Common Stock Reorganization.

3.3. Failure to File Registration  Statement.  In the event that ERHC shall fail
for any reason to file the  Registration  Statement on Form S-1 or S-3 (or their
then current  equivalents)  with the SEC as provided for herein on or before the
day which is ninety (90) days from the date hereof,  the Exercise Price shall be
decreased by twenty  percent  (20%).  Thereafter,  the  Exercise  Price shall be
decreased by an additional  twenty  percent  (20%)  (calculated  without  giving
effect  to any  adjustment  to the  Exercise  Price  pursuant  to the  foregoing
sentence) for each  additional  sixty (60) day period that elapses in which said
registration statement remains unfiled after the initial ninety (90) day period.
<PAGE>
3.4. Capital  Reorganizations.  If there shall be any consolidation or merger to
which ERHC is a party,  other than a consolidation  or a merger of which ERHC is
the continuing corporation and which does not result in any reclassification of,
or change (other than a Common Stock  Reorganization)  in, outstanding shares of
Common  Stock,  or any sale or conveyance of the property of ERHC as an entirety
or substantially as an entirety, or any recapitalization of ERHC (any such event
being called a "Capital  Reorganization"),  then,  effective  upon the effective
date of such Capital  Reorganization,  the Holder shall no longer have the right
to purchase  Common  Stock,  but shall have instead the right to purchase,  upon
exercise  of this  Warrant,  the kind and  amount  of  shares of stock and other
securities  and property  (including  cash) which the Holder would have owned or
have been entitled to receive  pursuant to such Capital  Reorganization  if this
Warrant  had been  exercised  immediately  prior to the  effective  date of such
Capital Reorganization.  As a condition to effecting any Capital Reorganization,
ERHC or the  successor  or  surviving  corporation,  as the case  may be,  shall
execute and deliver to Holder and to ERHC an agreement as to the Holder's rights
in accordance  with this Section 3.4,  providing,  to the extent of any right to
purchase  equity  securities  hereunder,  for  subsequent  adjustments as nearly
equivalent as may be practicable to the adjustments provided for in this Article
III. The  provisions  of this Section 3.4 shall  similarly  apply to  successive
Capital Reorganizations.

3.5.  Adjustment  Rules.  Any adjustments  pursuant to this Article III shall be
made  successively  whenever  an  event  referred  to  herein  shall  occur.  No
adjustment shall be made pursuant to this Article III in respect of the issuance
from time to time of shares of Common Stock upon the exercise of this Warrant.

3.6.  Proceedings  Prior to Any  Action  Requiring  Adjustment.  As a  condition
precedent to the taking of any action which would require an adjustment pursuant
to this  Article  III,  ERHC  shall  take any  action  which  may be  necessary,
including obtaining regulatory  approvals or exemptions,  in order that ERHC may
thereafter  validly and legally issue as fully paid and nonassessable all shares
of Common Stock which the Holder is entitled to receive upon exercise thereof.

3.7.  Notice of Adjustment.  Not less than 10 nor more than 30 days prior to the
record date or effective date, as the case may be, of any
<PAGE>
action which will require an adjustment or readjustment pursuant to this Article
III, ERHC shall give notice to the Holder of such event,  describing  such event
in reasonable  detail and specifying  the record date or effective  date, as the
case may be, and, if determinable,  the required  adjustment and the computation
thereof.  If the required  adjustment  is not  determinable  at the time of such
notice,  ERHC shall give notice to the Holder of such adjustment and computation
promptly after such adjustment becomes determinable.

                                     WARRANT

                       To Purchase Shares of Common Stock
                                       of
                     ENVIRONMENTAL REMEDIATION HOLDING CORP.

Dated ____________, _____

In consideration of the amount of ____________________Dollars ($__________) paid
by _______________________to ENVIRONMENTAL REMEDIATION HOLDING CORP., a Colorado
corporation  ("ERHC"),  __________________  or registered  assigns ("Holder") is
entitled to purchase from ERHC, at the Exercise Price of $2.00 per share,  up to
______________________  (__________)  shares of ERHC Common  Stock,  $0.0001 par
value per share ("Common  Stock"),  subject to adjustment and upon the terms and
conditions  hereinafter  provided.  This Warrant may be exercised in whole or in
part, but in increments of at least Fifty Thousand  (50,000) shares, at any time
or from  time to time  after  _______________,  _____  and  prior to 5:00  p.m.,
Eastern  Standard  Time, on the first Business Day after the fourteen (24) month
period  following  the  date  of the  declaration  of  effectiveness  of  ERHC's
registration  statement  to be filed on Form S-1 or S-3 (or their  then  current
equivalents)  with the  Securities and Exchange  Commission  ("SEC") in order to
register the shares of Common Stock  underlying this Warrant (the  "Registration
Statement"), as further described in Section 1.6 below.

Certain terms used in this Warrant are defined in Article IV.

                                    ARTICLE I
               EXERCISE OF WARRANT; REGISTRATION OF WARRANT SHARES

1.1.  Method of  Exercise.  To exercise  this  Warrant in whole or in part,  the
Holder shall deliver,  on any Business Day, to ERHC at its principal offices (a)
this Warrant,  (b) a written notice in the form attached  hereto as Exhibit A of
such Holder's election to exercise this Warrant,  which notice shall specify the
number of shares of Common Stock to be purchased  (which shall be a whole number
of shares if for less than all the shares then issuable hereunder, and shall not
<PAGE>
be for less than Fifty Thousand (50,000 shares)), the denominations of the share
certificate  or  certificates  desired  and the  name or  names  in  which  such
certificates  are to be  registered,  and (c) payment of the aggregate  Exercise
Price with respect to such shares.

Such payment of the aggregate  Exercise  Price may be made, at the option of the
Holder,  by any  combination of (1) cash,  check or wire transfer in immediately
available  funds to ERHC in an amount equal to the product of the Exercise Price
multiplied  by the number of shares of Common  Stock  being  purchased  with the
proceeds of such cash,  check or wire  transfer,  or (2) a written notice to the
Company that the Holder is exercising  the Warrants (or a portion  thereof) on a
"cashless  net  exercise"  basis,  under  which ERHC shall issue and deliver the
number of Warrant Shares  purchased less the number of shares of Common Stock as
shall at the time of such exercise have an aggregate  Fair Market Value equal to
the  applicable  aggregate  Exercise  Price (and the  shares of Common  Stock so
withheld shall no longer be issuable  under this  Warrant).  In the event Holder
exercises  this  Warrant in whole or in part on a cashless  net basis,  the Fair
Market Value of the Common Stock shall  established  as of the close of business
on the  Business  Day  preceding  the date that  Holder's  notice of election to
exercise on a cashless net basis is delivered to ERHC.

ERHC shall,  as promptly as  practicable  and in any event within five  Business
Days after  receipt of such notice and payment,  execute and deliver or cause to
be executed and  delivered,  in accordance  with such notice,  a certificate  or
certificates  representing  the  aggregate  number of  shares  of  Common  Stock
specified in said notice.  The share  certificate or  certificates  so delivered
shall be in such  denominations as may be specified in such notice, and shall be
issued  in the  name of the  Holder  or such  other  name or  names  as shall be
designated in such notice.  This Warrant shall be deemed to have been  exercised
and such  certificate or certificates  shall be deemed to have been issued,  and
such  Holder or any other  Person so  designated  to be named  therein  shall be
deemed for all  purposes to have become a holder of record of shares,  as of the
date the aforementioned  notice and payment is received by ERHC. If this Warrant
shall have been exercised only in part,  ERHC shall,  at the time of delivery of
such certificate or certificates, deliver to the Holder a new Warrant evidencing
the rights to purchase the  remaining  shares of Common Stock called for by this
Warrant,  which new Warrant shall in all other  respects be identical  with this
Warrant,  or, at the request of the Holder,  appropriate notation may be made on
this  Warrant  which shall then be  returned  to the Holder.  ERHC shall pay all
expenses, taxes
<PAGE>
and other  charges  payable in  connection  with the  preparation,  issuance and
delivery  of  share  certificates  and  new  Warrants,  except  that,  if  share
certificates  or new Warrants  shall be registered in a name or names other than
the name of the Holder,  funds sufficient to pay all transfer taxes payable as a
result of such  transfer  shall be paid by the Holder at the time of delivery of
the  aforementioned  notice of exercise or  promptly  upon  receipt of a written
request of ERHC for payment.

1.2.  Shares to be Fully  Paid and  Nonassessable.  All  shares of Common  Stock
issued upon the exercise of this Warrant shall be validly issued, fully paid and
nonassessable.

1.3. No Fractional  Shares Required to be Issued.  ERHC shall not be required to
issue fractions of shares of Common Stock upon exercise of this Warrant.

1.4.  Reservation.  ERHC has duly reserved and will keep  available for issuance
upon  exercise of the Warrants the total  number of Warrant  Shares  deliverable
from time to time upon exercise of all Warrants from time to time outstanding.

1.5. Expiration Date of Warrant. This Warrant shall expire at 5:00 p.m., Eastern
Standard  Time,  on the first  Business  Day (the  "Expiration  Date") after the
fourteen  (14)  month  period  following  the  date  of  declaration  by the SEC
("Effective  Date") of the  effectiveness  of the  Registration  Statement to be
filed on Form S-1 or S-3 (or their  then  current  equivalents)  with the SEC in
order to register the shares of Common Stock underlying this Warrant.

1.6  Registration  of Warrant  Shares.  Within  ninety (90) days  following  the
issuance of this Warrant, ERHC will file with the SEC the Registration Statement
on Form S-1 or Form S-3 (or  their  then  equivalents)  to  register  under  the
Securities  Act the Common Stock issued or issuable  pursuant to the exercise of
this Warrant. ERHC will thereafter, as expeditiously as possible, (i) effect the
qualification  and  registration  of such  shares  of  Common  Stock  under  the
Securities Act and state  securities  laws, and (ii) maintain the  effectiveness
for up to fourteen (14) months of such Registration Statement.  Holder agrees to
provide ERHC, at ERHC's request,  with such  information  about Holder as it may
reasonably  request in order to effect the  registration  under the Registration
Statement.  ERHC will from time to time amend or  supplement  such  Registration
Statement and
<PAGE>
the  prospectus  contained  therein to the extent  necessary  to comply with the
Securities Act and state  securities laws. ERHC will provide Holder with as many
copies of the prospectus  contained in the Registration  Statement as Holder may
reasonably request.  ERHC shall furnish to Holder at Holder's request an opinion
of counsel for ERHC, dated the effective date of the Registration Statement, and
a "comfort" letter,  signed by ERHC's independent  accountants who have examined
and  reported  on  ERHC's  financial  statements  included  in the  Registration
Statement,  in each case addressing  such matters as are customarily  covered in
such  opinions.  ERHC  shall  bear all costs and  expenses  of the  Registration
Statement and registration procedures described in this Section 1.6.

1.7 Rule 144. ERHC  covenants and agrees that it will file on a timely basis any
and all  reports  required  to be filed by it under the  Securities  Act and the
Securities  Exchange Act of 1934, as amended, so as to enable Holder to sell the
Warrant  Shares  without  registration  under  the  Securities  Act  within  the
limitations  of the exemptions  provided by Rule 144 of the  Securities  Act, as
such Rule may be amended  from time to time (or any similar  rule adopted by the
SEC).

2.1. Ownership of Warrant. ERHC may deem and treat the person in whose name this
Warrant  is  registered  as the  holder and owner  hereof  (notwithstanding  any
notations of ownership or writing hereon made by any person other than ERHC) for
all purposes and shall not be affected by any notice to the contrary,  until due
presentment  of this  Warrant for  registration  of transfer as provided in this
Article II.

2.2. Transfer of Warrant.  The Holder may sell, assign,  transfer,  give away or
otherwise  dispose of (any of the  foregoing,  a "Transfer") in whole or in part
its Warrants or Warrants Shares to any Person,  provided that Holder shall first

its principal  offices books for the  registration of transfers of the Warrants,
and transfer of this Warrant and all rights  hereunder  shall be registered,  in

the holders hereof and thereof or their  respective  duly  authorized  agents or
attorneys.  ERHC shall execute and deliver a new Warrant or Warrants in exchange
for the Warrant or Warrants  to be divided or combined in  accordance  with such

destruction,  upon receipt of indemnity or security  satisfactory to ERHC or, in
the  case of any  such  mutilation,  upon  surrender  and  cancellation  of such
Warrant, ERHC will make and deliver, in lieu of such lost, stolen,  destroyed or
mutilated  Warrant,  a new Warrant of like tenor and  representing  the right to
purchase the same aggregate number of shares of Common Stock.

                                   ARTICLE III
                             ANTIDILUTION PROVISIONS

3.1. Adjustment Generally. The Exercise Price and the number of shares of Common
Stock (or other  securities or property)  issuable upon exercise of this Warrant
shall be subject to adjustment  from time to time upon the occurrence of certain
events as provided in this Article III; provided that  notwithstanding  anything
to the contrary  contained herein, the Exercise Price shall not be less than the
current par value of the Common Stock.

3.2. Common Stock  Reorganization.  If ERHC after the original  issuance date of
the Warrants  shall  subdivide  its  outstanding  shares of Common Stock (or any
class thereof) into a greater number of shares or  consolidate  its  outstanding
shares of Common Stock (or any class  thereof)  into a smaller  number of shares
(any such event  being  called a "Common  Stock  Reorganization"),  then (a) the
Exercise Price shall be adjusted, effective immediately after the effective date
of such Common Stock  Reorganization,  to a price  determined by multiplying the
Exercise Price in effect immediately prior to such effective date by a fraction,
the numerator of which shall be the number of shares of
<PAGE>
Common Stock  outstanding  (on a Fully  Diluted  Basis) on such  effective  date
before giving effect to such Common Stock Reorganization, and the denominator of
which  shall be the  number of shares of Common  Stock  outstanding  (on a Fully
Diluted Basis) after giving effect to such Common Stock Reorganization,  and (b)
the number of shares of Common Stock  subject to purchase  upon exercise of this
Warrant  shall be adjusted,  effective at such time,  to a number  determined by
multiplying the number of shares of Common Stock subject to purchase immediately
before such Common Stock  Reorganization  by a fraction  the  numerator of which
shall be the number of shares of Common Stock  outstanding  (on a Fully  Diluted
Basis)  after  giving  effect  to  such  Common  Stock  Reorganization,  and the
denominator  of which shall be the number of shares of Common Stock  outstanding
(on a Fully Diluted Basis) immediately before such Common Stock Reorganization.

3.3. Failure to File Registration  Statement.  In the event that ERHC shall fail
for any reason to file the  Registration  Statement on Form S-1 or S-3 (or their
then current  equivalents)  with the SEC as provided for herein on or before the
day which is ninety (90) days from the date hereof,  the Exercise Price shall be
decreased by twenty  percent  (20%).  Thereafter,  the  Exercise  Price shall be
decreased by an additional  twenty  percent  (20%)  (calculated  without  giving
effect  to any  adjustment  to the  Exercise  Price  pursuant  to the  foregoing
sentence) for each  additional  sixty (60) day period that elapses in which said
registration statement remains unfiled after the initial ninety (90) day period.

3.4. Capital  Reorganizations.  If there shall be any consolidation or merger to
which ERHC is a party,  other than a consolidation  or a merger of which ERHC is
the continuing corporation and which does not result in any reclassification of,
or change (other than a Common Stock  Reorganization)  in, outstanding shares of
Common  Stock,  or any sale or conveyance of the property of ERHC as an entirety
or substantially as an entirety, or any recapitalization of ERHC (any such event
being called a "Capital  Reorganization"),  then,  effective  upon the effective
date of such Capital  Reorganization,  the Holder shall no longer have the right
to purchase  Common  Stock,  but shall have instead the right to purchase,  upon
exercise  of this  Warrant,  the kind and  amount  of  shares of stock and other
securities  and property  (including  cash) which the Holder would have owned or
have been entitled to receive pursuant to such Capital Reorganization if this
<PAGE>
Warrant  had been  exercised  immediately  prior to the  effective  date of such
Capital Reorganization.  As a condition to effecting any Capital Reorganization,
ERHC or the  successor  or  surviving  corporation,  as the case  may be,  shall
execute and deliver to Holder and to ERHC an agreement as to the Holder's rights
in accordance  with this Section 3.4,  providing,  to the extent of any right to
purchase  equity  securities  hereunder,  for  subsequent  adjustments as nearly
equivalent as may be practicable to the adjustments provided for in this Article
III. The  provisions  of this Section 3.4 shall  similarly  apply to  successive
Capital Reorganizations.

3.5.  Adjustment  Rules.  Any adjustments  pursuant to this Article III shall be
made  successively  whenever  an  event  referred  to  herein  shall  occur.  No
adjustment shall be made pursuant to this Article III in respect of the issuance
from time to time of shares of Common Stock upon the exercise of this Warrant.

3.6.  Proceedings  Prior to Any  Action  Requiring  Adjustment.  As a  condition
precedent to the taking of any action which would require an adjustment pursuant
to this  Article  III,  ERHC  shall  take any  action  which  may be  necessary,
including obtaining regulatory  approvals or exemptions,  in order that ERHC may
thereafter  validly and legally issue as fully paid and nonassessable all shares
of Common Stock which the Holder is entitled to receive upon exercise thereof.

3.7.  Notice of Adjustment.  Not less than 10 nor more than 30 days prior to the
record  date or  effective  date,  as the case may be, of any action  which will
require an adjustment or  readjustment  pursuant to this Article III, ERHC shall
give notice to the Holder of such  event,  describing  such event in  reasonable
detail and  specifying  the record date or effective  date,  as the case may be,
and, if determinable,  the required  adjustment and the computation  thereof. If
the required  adjustment is not  determinable  at the time of such notice,  ERHC
shall give  notice to the Holder of such  adjustment  and  computation  promptly
after such adjustment becomes determinable.

percent of the  original  principal  amount of this Note,  into shares of Common
Stock of the Company,  by written notice given to the Company in accordance with
the provisions of Section 4(h) hereof (the "Conversion Notice"). In no event may

Company at any time during normal  business  hours at the office of the Company,
accompanied (i) by the Conversion Notice, (ii) if so required by the Company, by
instruments of transfer,  in form satisfactory to the Company,  duly executed by

stamps or funds therefore, if required pursuant to Section 4(g) herein.
<PAGE>
b)  Conversion  Price.  Subject to  adjustment  from time to time as provided in

c) Adjustments of Conversion  Price. The Conversion Price in effect from time to
time shall be,  subject to adjustment in accordance  with the provisions of this
Section 4(c).

         (i) Adjustments for Stock Splits and Combinations. If the Company shall
at any time or from time to time after the Issuance  Date,  effect a stock split
of the  outstanding  Common Stock,  the  applicable  Conversion  Price in effect
immediately prior to the stock split shall be proportionately  decreased. If the
Company shall at any time or from time to time after the Issuance Date,  combine
the  outstanding  shares of Common Stock,  the  applicable  Conversion  Price in
effect immediately prior to the combination shall be proportionately  increased.
Any  adjustments  under this Section  4(c)(i) shall be effective at the close of
business on the date the stock split or combination occurs.

         (ii)  Adjustments  for  Certain  Dividends  and  Distributions.  If the
Company shall at any time or from time after the Issuance Date, make or issue or
set a record date for the  determination  of holders of Common Stock entitled to
receive a dividend  or other  distribution  payable  in shares of Common  Stock,
then, and in each event, the applicable  Conversion Price in effect  immediately
prior to such event shall be  decreased  as of the time of such  issuance or, in
the event such a record date shall have been fixed,  as of the close of business
on such record date, by multiplying,  as applicable,  the applicable  Conversion
Price then in effect by a fraction;

                  (A) the numerator of which shall be the total number of shares
of Common Stock  issued and  outstanding  immediately  prior to the time of such
issuance or the close of business on such record date; and

                  (B) the  denominator  of which  shall be the  total  number of
shares of Common Stock issued and outstanding  immediately  prior to the time of
such  issuance  or the close of  business on such record date plus the number of
shares of Common Stock issuable in payment of such dividend or distribution.
<PAGE>
         (iii) Adjustment for Other Dividends and Distributions.  If the Company
shall at any time or from time to time after the Issuance Date, make or issue or
set a record date for the  determination  of holders of Common Stock entitled to
receive a dividend or other distribution  payable in other than shares of Common
Stock, then, and in each event, an appropriate  revision to the Conversion Price
shall be made and  provision  shall be made (by  adjustments  of the  Conversion
Price  or  otherwise)  so that  the  holder  of this  Note  shall  receive  upon
conversions  thereof,  in  addition  to the  number of  shares  of Common  Stock
receivable  thereon,  the number of  securities  of the Company which they would
have received had this Note been converted into Common Stock on the date of such
event and had  thereafter,  during the period from the date of such event to and
including the  Conversion  Date,  retained such  securities  (together  with any
distributions  payable  thereon during such period),  giving  application to all
adjustments  called for during such period  under this  Section  4(c)(iii)  with
respect to the rights of the holders of the Note.

         (iv) Adjustments for Reclassification, Exchange or Substitution. If the
Common Stock  issuable upon  conversion of this Note at any time or from time to
time after the Issuance Date shall be changed into the same or different  number
of  shares of any  class or  classes  of  stock,  whether  by  reclassification,
exchange,  substitution  or  otherwise  (other  than by way of a stock  split or
combination of shares or stock dividends provided for in Sections 4(c)(i),  (ii)
and  (iii),  or a  reorganization,  merger,  consolidation,  or sale  of  assets
provided  for in Section  4(c)(v)),  then,  and in each  event,  an  appropriate
revision to the Conversion  Price shall by made and provisions shall be made (by
adjustments  of the  Conversion  Price of  otherwise) so that the holder of this
Note shall  have the right  thereafter  to  convert  such Note into the kind and
amount of shares of stock and other securities receivable upon reclassification,
exchange,  substitution  or other change,  by holders of the number of shares of
Common Stock into which such Note might have been converted immediately prior to
such  reclassification,  exchange,  substitution or other change, all subject to
further adjustment as provided herein.

         (v) Adjustments for Reorganization,  Merger,  Consolidation or Sales of
Assets. If at any time or from time to time after the  Issuance Date there shall
be a capital reorganization of the Company
<PAGE>
(other than by way of a stock split or combination of shares or stock  dividends
or  distributions  provided  for  in  Section  4(c)(i),  (ii)  and  (iii),  or a
reclassification,  exchange or  substitution  of shares  provided for in Section
4(c)(iv)),  or a merger or  consolidation  of the Company  with or into  another
corporation, or the sale of all or substantially all of the Company's properties
or assets to any other person,  then as a part of such  reorganization,  merger,
consolidation, or sale, an appropriate revision to the Conversion Price shall be
made and provision  shall be made (by  adjustments  of the  Conversion  Price or
otherwise)  so that the holder of this Note shall have the right  thereafter  to
convert  this  Note  into the kind and  amount  of  shares  of stock  and  other
securities  or property of the Company or any  successor  corporation  resulting
from such reorganization,  merger, consolidation,  or sale, to which a holder of
Common Stock deliverable upon conversion of such shares would have been entitled
upon such reorganization,  merger, consolidation,  or sale, to which a holder of
Common Stock deliverable upon conversion of such shares would have been entitled
upon such  reorganization,  merger,  consolidation,  or sale.  In any such case,
appropriate  adjustment  shall be made in the  application  of the provisions of
this  Section  4(c)(v)  with  respect to the rights of the  holders of this Note
after the  reorganization,  merger,  consolidation,  or sale to the end that the
provisions of this Section  4(c)(v)  (including any adjustment in the applicable
Conversion  Ratio  then in  effect  and the  number  of shares of stock or other
securities deliverable upon conversion of this Note) shall be applied after that
event in as nearly an equivalent manner as may be practicable.

d) No  Impediment.  The Company  shall not, by amendment of its  Certificate  of
Incorporation or through any reorganization,  transfer of assets, consolidation,
merger, dissolution,  issue or sale of securities or any other voluntary action,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed or performed  hereunder  by the Company,  but will at all times in good
faith, assist in the carrying out of all the provisions of this Section 4 and in
the taking of all such action as may be  necessary  or  Appropriate  in order to
protect the Conversion Rights of the holders of the Note against impairment.

e)  Certificate  as to  Adjustments.  Upon  occurrence  of  each  adjustment  or
readjustment  of the  Conversion  Price or number  of  shares  of  Common  Stock
issuable upon conversion of the Note pursuant to this Section 4,
<PAGE>
the  Company  at  its  expense  shall  promptly   compute  such   adjustment  or
readjustment  in  accordance  with the terms  hereof and furnish  notice to each
holder  of  such  Note,  a  certificate   setting  forth  such   adjustment  and
readjustment,  showing  in detail  the  facts  upon  which  such  adjustment  or
readjustment is based. The Company shall,  upon written request of the holder of
this Note,  at any time,  furnish or cause to be furnished to such holder a like
certificate  setting forth such  adjustments and  readjustments,  the applicable
Conversion  Price in effect at the time and the number of shares of Common Stock
and the amount,  if any, of other securities or property which at the time would
be received upon the conversion of such Note. Notwithstanding the foregoing, the
Company shall not be obligated to deliver a certificate  unless such certificate
would  reflect an increase or decrease of at least one percent of such  adjusted
amount.

f) Issue  Taxes.  The  Company  shall pay any and all  issue  and  other  taxes,
excluding  federal,  state or local income taxes, that may be payable in respect
of any issue or delivery of shares of Common  Stock on  conversion  of this Note
pursuant hereto;  provided,  however, that the Company shall not be obligated to
pay any transfer taxes  resulting  from any transfer  requested by any holder in
connection with any such conversion.

g)  Notices  and  Delivery  of  Shares.  All  notices  and other  communications
hereunder shall be in writing and shall be deemed given (i) on the same date, if
delivered  personally  or by facsimile by not later than 7:00 p.m. New York time
(provided,  that a copy of such facsimile shall be simultaneously sent to Donald
F. Mintmire, Esq. at (561)832-5696,  or (ii) three business days following being
mailed  by  certified  or  registered  mail,  postage  prepaid,   return-receipt
requested,  addressed  to the holder of record at its address  appearing  on the
books of the Company. Not later than five (5) Business Days following receipt of
notice of conversion as provided herein (the "Delivery Date"), the Company shall
deliver  to  the  holders  of  this  Note,  against  delivery  of  one  or  more
certificates evidencing Note surrendered for conversion, certificates evidencing
all shares of Common Stock into which this Note shall be converted.

h) Fractional  Shares. No fractional shares of Common Stock shall be issued upon
conversion  of the Note.  In lieu of any  fractional  shares to which the holder
would otherwise be entitled, the Company shall pay
<PAGE>
cash equal to the product of such fraction multiplied by the Conversion Price of
one share of the Company's Common Stock on the applicable Conversion Date.

i) Reservation of Common Stock.  The Company shall at all times reserve and keep
available,  out of its authorized but unused shares of Common Stock,  solely for
the purpose of effecting the  conversion of the Note,  the full number of shares
deliverable upon conversion of all the Note from time to time  outstanding.  The
Company  shall,  from  time to time in  accordance  with  the  Colorado  General
Corporations Law, as amended, increase the authorized number of shares of Common
Stock if at any  time the  unused  number  of  authorized  shares  shall  not be
sufficient to permit the conversion of all of the Note at the time  outstanding.
In such connection, the Company shall hold a special meeting of stockholders for
the purpose of authorizing  additional shares of Common Stork not later than 120
days  after any date in which the  Company  shall  have  insufficient  shares of
Common Stock so reserved.

j)  Retirement  of Note.  Conversion  of this Note  shall be deemed to have been
effected on the  applicable  Conversion  Date.  The  converting  holder shall be
deemed  to have  become a  stockholder  of  record  of the  Common  Stock on the
applicable  Conversion Date. Upon conversion of only a portion of this Note, the
Company  shall issue and  deliver to such holder at the expense of the  Company,
against receipt of the original note delivered for partial  cancellation,  a new
Note representing the unconverted portion of this Note so surrendered.

k)       Regulatory Compliance.

         (i) If any shares of Common  Stock to be  reserved  for the  purpose of
conversion of this Note require  registration or listing with or approval of any
government authority,  stock exchange or other regulatory body under any federal
or state law or regulation or otherwise before such shares may be validly issued
or delivered upon  conversion,  the Company shall, at its sole cost and expense,
in good  faith  and as  expeditiously  as  possible,  endeavor  to  secure  such
registration, listing or approval, as the case may be.

         (ii) The shares of Common Stock  issuable  upon the election to convert
shall be Rule 144 restricted shares (the "Restricted
<PAGE>
Securities").  After  issuance  of the  Shares,  Company  agrees to use its best
efforts to assist holder in registering the Restricted Securities or to register
the Restricted Securities under the Act subject to the rules,  regulations,  and
other provisions of said Act.

         (iii) In the event the  holder  elects to  convert  into  ownership  of
shares of the Company  Stock,  at the time of such  conversation,  the holder of
such shares shall have the following piggyback rights with reference:

                  (A) At any time that the  Company  proposes  to file a Company
registration  statement on Form S-1, including the pending Form S-1 registration
filed on January 8, 1998,  under the Act (the  "Registrations  Statement"),  the
Company shall cause to be included in such registration statement any securities
issued or subject to issuance in this transaction;  provided,  however, that if,
at any time  after  giving  written  notice of its  intention  to  register  any
securities and prior to the effective date of the Company Registration Statement
filed in connection with such registration,  the Company shall determine for any
reason  not  to  register  or  to  delay  registration  of  holder's  Restricted
Securities,  the  Company  may, at its  election,  give  written  notice of such
determination to holder and, thereupon:

                           (1) in the ease of a determination not to register,
shall be relieved of its obligation to register holder's  Restricted  Securities
in connection  with such  registration  (but not from its  obligation to pay the
registration expenses in connection therewith), and

                           (2) in the case of a delay in registering, shall be
permitted  to delay  registering  holder's  Restricted  Securities  for the same
period as the delay in registering such other securities.

                  (B) The Company's obligation to include Restricted  Securities
in a Company's  Registration Statement pursuant to Section 7(a) shall be subject
to the following limitations:

                           (1) The Company may elect, at its sole option and for
any reason, not to register holder's Restricted Shares,  provided however,  that
this right is limited to one (1) time and relative to
<PAGE>
one (1) particular Company Registration Statement.

                           (2) The Company shall not be obligated to include any
Restricted Securities in a registration statement filed on Form S-4, Form S-8 or
such other similar successor forms then in effect under the Securities Act.

                           (3) If a Company Registration Statement involves an
underwritten  offering  and the  managing  underwriter  advises  the  Company in
writing that in its opinion,  the number of securities  requested to be included
in such Company  Registration  Statement exceeds the number which can be sold in
such  offering  without  adversely  affecting  the  offering,  the Company shall
include in such Company  Registration  Statement  the number of such  securities
which the Company is so advised can be sold in such offering  without  adversely
affecting the offering, determined as follows:

                               (i) first, the securities proposed by the Company
to be sold for it own account, and

                               (ii) second, any Restricted Securities  requested
to be included in such  registration  and any other securities of the Company in
accordance with the  priorities,  if and then existing among the holders of such
securities pro rata among the holders thereof  requesting  such  registration on
the basis of the number of shares of such securities requested to be included by
such holders.

                           (4) The  Company  shall  not  be obligated to include
Restricted Securities in more than one (1) Company Registration Statement.

                  (C) To the extent holder's Restricted  Securities are intended
to be included in a Company  Registration  Statement,  holder may include any of
its Restricted  Securities in such Company  Registration  Statement  pursuant to
this  Agreement only if holder  furnishes to the Company in writing,  within ten
(10) business days after receipt of a written request therefor, such information
specified in Item 507 of Regulation S-K under the Act or such other  information
as the Company may  reasonably  request for use in  connection  with the Company
Registration  Statement or Prospectus or preliminary Prospectus included therein
and in any application to the NASD. Holder as to which the Company  Registration
Statement  is being  effected  agrees to furnish  promptly  to the  Company  all
information
<PAGE>
required to be disclosed in order to make all information  previously  furnished
to the Company by holder not materially misleading.

l) Limitations on Amount of Conversion.  Notwithstanding  anything  contained in
this Note to the  contrary,  in no event shall any holder of Note be entitled or
required to convert  this Note in excess of that number of shares of Note which,
upon  giving  effect to such  conversion,  would cause the  aggregate  number of
shares of Common Stock  beneficially  owned by the holder and its  affiliates to
exceed 4.9% of the outstanding  shares of the Company's Common Stock immediately
following such conversion.  For purposes of the foregoing proviso, the aggregate
number of  shares  of Common  Stock  beneficially  owned by the  holder  and its
affiliates  shall  include the number of shares of Common  Stock  issuable  upon
conversion of this Note with respect to which the  determination of such proviso
is being  made,  but shall  exclude  the number of shares of Common  Stock which
would be  issuable  upon  (i)  conversion  of the  remaining,  unconverted  Note
beneficially  owned by such  holder and its  affiliates,  and (ii)  exercise  or
conversion of the unexercised or unconverted  portion of any other securities of
the Company  (including  without limitation any warrants) which are beneficially
owned by the holder and its  affiliates and which are subject to a limitation on
conversion or exercise analogous to the limitation  contained herein.  Except as
set forth in the preceding sentence, for purposes of this paragraph,  beneficial
ownership shall be calculated in accordance with Section 13(d) of the Securities
Exchange  Act of 1934,  as amended.  Any holder of Note may waive the  foregoing
limitations  set forth in this  paragraph by written  notice to the Company upon
not less than 30 days prior notice (with such waiver taking effect only upon the
expiration of such 30-day notice period).

9. SUBORDINATION TO SENIOR DEBT.

a) Payment of the principal of and interest on this Note is subordinated, to the
extent  and  in  the  manner  provided  herein,  to  the  prior  payment  of all
indebtedness of the Company and/or all  Subsidiaries  of the Company,  for money
borrowed  or  other   obligations   which  is  now  or  may  hereafter  be  owed
(collectively,  "Senior Debt") to any bank, commercial finance company,  factor,
insurance company or other  institution the lending  activities are regulated by
law (individually, a "Senior Lender" and collectively,  "Senior Lenders"), which
may,  hereafter on any one or more occasions provide financing to the Company or
any of its Subsidiaries, secured by liens on any of the assets and properties of
the Company and/or any of its Subsidiaries  (individually and  collectively,  an
"Institutional Borrower").

b) Upon any payment or distribution of assets or securities of the Institutional
Borrower,  as the  case  may be,  of any  kind or  character,  whether  in cash,
property or securities,  upon any  dissolution or winding up or total or partial
liquidation or reorganization of the Institutional  Borrower,  whether voluntary
or involuntary or in bankruptcy, insolvency,  receivership or other proceedings,
all amounts  payable  under Senior Debt shall first be paid in full in cash,  or
payment provided for in cash or cash equivalents, before the holder hereof shall
be entitled to receive  any  payment on account of  principal  of or interest on
this Note. Before any payment may be made by the  Institutional  Borrower of the
principal of or interest on this
<PAGE>
Note upon any such  dissolution or winding up or liquidation or  reorganization,
any  payment  or  distribution  of assets  or  securities  of the  Institutional
Borrower of any kind of character,  whether in cash, property or securities,  to
which the holder  hereof would be entitled,  except for the  provisions  of this
Section  9,  shall be made by the  Institutional  Borrower  or by any  receiver,
trustee in bankruptcy,  liquidating  trustee,  agent or other person making such
payment  or  distribution,  directly  to the  holders  of  Senior  Debt or their
representatives  to the extent  necessary  to pay all such  Senior  Debt in full
after giving effect to any concurrent  payment or distribution to the holders of
such Senior Debt.

c) Upon the  happening of any default in payment of the principal of or interest
on any Senior Debt, then, unless and until such default shall have been cured or
waived or shall have  ceased to exist,  no direct or  indirect  payment in cash,
property or securities,  by set-off or otherwise,  shall be made or agreed to be
made by the Institutional Borrower on account of the principal of or interest on
this Note.

d) Upon the  happening  of an event of default  (other than under  circumstances
when the terms of Section 9(c) above are applicable)  with respect to any Senior
Debt  pursuant to which the holder  thereof is entitled  under the terms of such
Senior Debt to accelerate the maturity thereof,  and upon written notice thereof
given to each of the Institutional  Borrower and the holder of this Note by such
holder of Senior Debt ("Payment  Notice"),  then, unless and until such event of
default shall have been cured or waived or shall have ceased to exist, no action
shall or may be taken for  collection  of any  amounts  under this Note,  and no
direct or  indirect  payment  in cash,  property  or  securities,  by set-off or
otherwise,  shall be made or agreed to be made by the Institutional  Borrower an
account of the  principal of or interest on this Note until such Senior Debt has
been paid in full accordance with its terms.

e) In the event than,  notwithstanding  the  provisions  of this  Section 9, any
payment shall be made on account of the principal of or interest on this Note in
contravention  of such  provisions,  then  such  payment  shall  be held for the
benefit of, and shall be paid over and  delivered to, the holders of such Senior
Debt remaining unpaid to the
<PAGE>
extent necessary to pay in fall in cash or cash equivalents the principal of and
interest on such Senior Debt in accordance with its terms after giving effect to
any concurrent payment or distribution to the holders of such Senior Debt.

f)       Nothing contained in this Section 9 shall

         (i) impair the conversion rights of the holder hereof referred to
in Section 4 above,

         (ii)  impair,  as between the Company and the holder of this Note,  the
obligation of the Company,  which is absolute and  unconditional,  to pay to the
holder  hereof  principal and interest as the same shall become due and payable,
or (iii)  prevent the holder  hereof  from  exercising  all  rights,  powers and
remedies  otherwise  provided  herein or by  applicable  law, all subject to the
express limitations provided herein.

g) Upon the occurrence of an Event of Default,  if any Senior Debt shall then be
outstanding,  no  acceleration  of the  maturity of this Note shall be effective
until the earlier of (i) ten (10) days shall have passed  following  the date of
delivery to the  Institutional  Borrower by a Senior Lender(s) of written notice
of acceleration of any Senior Debt, or (ii) the maturity of any then outstanding
Senior  Debt  shall have been  accelerated  by reason of a default  hereon.  The
Company may pay the holder  hereof any  defaulted  payment and all other amounts
due following any such acceleration of the maturity of this Note if this Section
9 would not prohibit such payment to be made at that time.

h) Upon  payment  in full of all  Senior  Debt,  the Payee of this Note shall be
subrogated  to the rights of the holder or holders of Senior Debt to receive all
payments or  distributions  applicable on Senior Debt to the extent of the prior
application  thereto of moneys or other assets which would have been received in
respect  of this  Note,  but  for  these  subordination  provisions,  until  the
principal of, and interest on, this Note shall have been paid in full.

i)       The Payee, by accepting this Note
<PAGE>
         (i) shall be bound by all of the foregoing subordination
provisions;

         (ii) agrees expressly for the benefit of the present and future holders
of  Senior  Debt  that  this  Note is  subject  to the  foregoing  subordination
provisions;  (iii) authorizes such persons as shall be designated by all holders
of Senior Debt at any given  time,  on his or its benefit to execute and deliver
such agreements, assignments, proofs of claim and other documents appropriate to
effectuate the foregoing subordination provisions;  and (iv) hereby appoints the
person so designated his or its attorney-in-fact for such purpose.

j) The  foregoing  subordination  provisions  shall  be for the  benefit  of all
holders of Senior Debt from time to time  outstanding,  and each of such holders
may proceed to enforce such provisions either directly against the holder hereof
or in any other manner provided by law.

k)  Notwithstanding  anything to the  contrary  set forth in this Section 9, the
security interest of the holder of this Note (as specified in Section 10 hereof)
is subject and subordinated  only to the prior first lien and security  interest
of any  holder  of  Senior  Debt  of the  Company,  unless  otherwise  expressly
consented to in writing by the Payee.

10. PERMITTED PAYMENTS.

Notwithstanding  the  provisions of Section 9 of this Note, and provided that no
default or event of default (or event which,  with the passage of time or giving
of notice  or both)  has  occurred,  will  occur as a result  of the  "Permitted

                 ENVIRONMENTAL REMEDIATION HOLDING CORPORATION

                    Redeemable Common Stock Purchase Warrant

                       VOID AFTER 5:00 P.M., EASTERN TIME

                                  June 18, 2002

         FOR VALUE RECEIVED,  Environmental  Remediation Holding Corporation,  a
Colorado corporation (the "Company"), promises to issue in the name of, and sell
and  deliver  to  ___________,   (the  "Holder"),  or  the  Holder's  registered
transferee or assignee (also the "Holder"), a certificate or certificates for an
aggregate of _________ shares (the "Shares") of Common Stock,  $0.0001 par value
per share (the "Common Stock"), of the Company, (i) at any time on or before the
later  of 5:00  p.m.,  Eastern  Time,  on June 18,  2000  (the  "First  Exercise
Period"),  upon  payment  therefore  of $0.50 per  Share in lawful  funds of the
United States of America or thereafter  and (ii) on or before June 18, 2002 (the
"Second  Exercise  Period") upon payment  therefore of $0.85 per share in lawful
funds of the United States of America.  In the event the Warrants and underlying
shares are not  registered  as provided  herein on or before six (6) months from
the date hereof the Warrant  exercise price for the Second Exercise Period shall
remain  $0.50  for the term of the  Warrant(s).  And  further,  in the event the
shares are registered as provided herein at any time prior to June 18, 2002, and
the market price drops below $.75 after ninety (90) days from the effective date
of such registration for (i) more than five (5) consecutive trading days or (ii)
seven (7) out of ten (10)  trading  days,  then the  exercise  price  thereafter
during the balance of the term of this Warrant shall be equal to fifty percent
<PAGE>
(50%) of the average  closing  price for the ten (10) trading  days  immediately
preceding the Date of Exercise as defined herein.

         1.  Exercise of the Warrant.  In case the Holder of this Warrant  shall
desire to exercise this Warrant in whole or in part, the Holder shall  surrender
this  Warrant,  with the form of  exercise  notice on the last page  hereof duly
executed by the Holder,  to the Company,  accompanied by payment of the Exercise
Price per Warrant.

                  (a) This  Warrant may be exercised in whole or in part but not
for  fractional  Shares.  In case of the exercise in part only, the Company will
deliver  to the  Holder a new  Warrant  of like  tenor in the name of the Holder
evidencing  the right to purchase  the number of Shares as to which this Warrant
has not been exercised.

                  (b) This Warrant may also be exercised by the Warrant  Holder,
in  whole or in part,  at any time and from  time to time and from  time to time
during the Exercise Period by presentation  and surrender of this Warrant to the
Company at its principal  executive offices with a written notice of the Warrant
Holder's intention to effect a cashless exercise, including a calculation of the
number of shares of Common Stock to be issued upon such  exercise in  accordance
with the  terms  hereof (a  "Cashless  Exercise").  In the  event of a  Cashless
Exercise,  the holder shall  surrender this Warrant for that number of shares of
Common Stock determined by

                            (i) multiplying  the number of Shares for which this
Warrant is being exercised by the per share warrant value as defined in  Section
1(c) herein; and

                           (ii) dividing the product by the  bid  price  of  one
share of the Common Stock on the trading day next preceding the date of exercise
as defined in Section 1(d) hereof.

In the event that the  Warrant is not  exercised  in full,  the number of Shares
shall be  reduced  by the  number of such  Shares  for  which  this  Warrant  is
exercised, and the Company, at its expense, shall forthwith issue and deliver to
or upon the order of the Holder a new Warrant of
<PAGE>
like tenor in the name of the Holder or as the  Holder may  request,  reflecting
such adjusted number of Shares.

                  (c) As used herein "Per Share  Warrant  Value"  shall mean the
difference  resulting from  subtracting the Exercise Price from the bid price of
one  share  of  Common  Stock on the  trading  day  next  preceding  the Date of
Exercise.

                  (d) As used herein "Date of Exercise" shall mean the date that
the advance  copy of the Form of Exercise  set forth herein is sent by facsimile
to the  Company,  provided  that the  original  Warrant and Form of Exercise are
received by the Company  within three (3) business  days. If the Warrant  Holder
has not sent advance notice by facsimile, the Date of Exercise shall be the date
the original Form of Exercise is received by the Company.

         2.  Covenants of the Company.  The Company hereby covenants and  agrees
that prior to the expiration of this Warrant by exercise or by its terms:

                  (a) The Company shall at all times reserve and keep available,
out of its  authorized  and unissued  share  capital,  solely for the purpose of
providing  for the  exercise,  forthwith  upon the  request of the Holder of the
Warrants then outstanding and in effect,  such number of shares of Common Stock,
as shall, from time to time, be sufficient for the exercise of the Warrants. The
Company  shall,  from time to time, in accordance  with the laws of the State of
Florida,  increase the authorized amount of its share capital if at any time the
number of shares of Common Stock  remaining  unissued and  unreserved  for other
purposes  shall not be  sufficient  to permit the exercise of the Warrants  then
outstanding and in effect.

                  (b) The Company  covenants and agrees that all shares that may
be issued upon the exercise of the rights represented by this Warrant will, upon
issuance,  be validly issued,  fully paid and non-assessable,  and free from all
taxes, liens and charges with respect to the issue thereof.
<PAGE>
         3.  Loss, Theft, Destruction or Mutilation.  In case this Warrant shall
become mutilated or defaced or be destroyed,  lost or stolen,  the Company shall
execute  and  deliver a new  Warrant  in  exchange  for and upon  surrender  and
cancellation  of  such  mutilated  or  defaced  Warrant  or in  lieu  of  and in
substitution for such warrant so destroyed,  lost, or stolen, upon the Holder of
such Warrant filing with the Company such evidence  satisfactory to it that such
Warrant has been so  mutilated,  defaced,  destroyed,  lost or stolen and of the
ownership thereof by the Holder;  provided,  however,  that the Company shall be
entitled,  as a condition to the execution and delivery of such new Warrant,  to
demand indemnity satisfactory to it and payment of expenses and charges incurred
in connection with the delivery of such new Warrant,  and may demand a bond from
the Holder. Any Warrant so surrendered to the Company shall be canceled.

         4. Record Owner. At the time of the surrender of this Warrant, together
with the form of  subscription  properly  executed  and payment of the  Exercise
Price,  the person  exercising  this Warrant shall be deemed to be the Holder of
record of the Common Stock deliverable upon such exercise,  in whole or in part,
notwithstanding  that the stock  transfer  books of the  Company  shall  then be
closed  or that  certificates  representing  such  securities  shall not then be
actually delivered to such person.

         5. Mailing of Notices,  etc. All notices and other  communications from
the  Company  to the  Holder of this  Warrant  shall be  mailed  by  first-class
registered or certified mail, return receipt requested,  potage prepaid,  to the
Holder at the address set forth in the records of the Company,  or to such other
address  furnished  to the Company in writing from time to time by the Holder of
this Warrant.

         6. Registration  Under the Securities Act of 1933, as amended.  Neither
this  Warrant  nor the  Shares  underlying  it have  been  registered  under the
Securities  Act of 1933,  as amended  (the "Act").  Unless and until  registered
under  the  Act,  this  Warrant  and all  replacement  Warrants  shall  bear the
following legend:

         This  Warrant,  and  the  securities issuable upon the exercise of this
         Warrant, have not been registered under the
<PAGE>
         Securities Act of 1933, as amended (the "Act") or applicable  state law
         and may not be  sold,  transferred  or  otherwise  disposed  of  unless
         registered  under the Act and any  applicable  state act or unless  the
         Company is satisfied that this Warrant and the underling securities may
         be transferred without registration under the Act.

         The Shares  issuable  upon  exercise of this Warrant  shall be Rule 144
         restricted shares (the "Restricted  Securities"). After issuance of the
         Shares,  Company  agrees to use its best  efforts  to assist  Holder in
         registering the Shares or to register the Shares under the Act  subject
         to the rules, regulations, and other provisions of said Act.

         7. Piggyback Registration.

                  (a) At any time that the  Company  proposes  to file a Company
registration  statement on Form S-1, including the pending Form S-1 registration
filed on January 8, 1998,  under the Act (the  "Registrations  Statement"),  the
Company shall cause to be included in such registration statement any securities
issued or subject to issuance in this transaction;  provided,  however, that if,
at any time  after  giving  written  notice of its  intention  to  register  any
securities and prior to the effective date of the Company Registration Statement
filed in connection with such registration,  the Company shall determine for any
reason  not  to  register  or  to  delay  registration  of  holder's  Restricted
Securities,  the  Company  may, at its  election,  give  written  notice of such
determination to holder and, thereupon:

                           (i) in the ease of a determination not to register,
shall be relieved of its obligation to register Holder's  Restricted  Securities
in connection  with such  registration  (but not from its  obligation to pay the
registration expenses in connection therewith), and

                           (ii) in the case of a delay in registering, shall be
permitted  to delay  registering  Holder's  Restricted  Securities  for the same
period as the delay in registering such other securities.
<PAGE>

                  (b) The  Company's obligation to include Restricted Securities
in a Company's Registration Statement pursuant to Section 7(a)  shall be subject
to the following limitations:

                           (i) The Company may elect, at its sole option and for
any reason, not to register Holder's Restricted Shares,  provided however,  that
this right is limited to one (1) time and relative to one (1) particular Company
Registration Statement.

                           (ii)The Company shall not be obligated to include any
Restricted Securities in a registration statement filed on Form S-4, Form S-8 or
such other similar successor forms then in effect under the Securities Act.

                           (iii) If a Company Registration Statement involves an
underwritten  offering  and the  managing  underwriter  advises  the  Company in
writing that in its opinion,  the number of securities  requested to be included
in such Company  Registration  Statement exceeds the number which can be sold in
such  offering  without  adversely  affecting  the  offering,  the Company shall
include in such Company  Registration  Statement  the number of such  securities
which the Company is so advised can be sold in such offering  without  adversely
affecting the offering, determined as follows:

                              (A)  first, the securities proposed by the Company
to be sold for it own account, and

                              (B) second, any Restricted Securities requested to
be  included in such  registration  and any other  securities  of the Company in
accordance with the  priorities,  if and then existing among the holders of such
securities pro rata among the holders thereof  requesting  such  registration on
the basis of the number of shares of such securities requested to be included by
such holders.

                           (iv) The Company shall not be  obligated  to  include
Restricted Securities in more than one (1) Company Registration Statement.

                  (c) To the extent Holder's Restricted  Securities are intended
to be included in a Company  Registration  Statement,  Holder may include any of
its Restricted  Securities in such Company  Registration  Statement  pursuant to
this  Agreement only if Holder  furnishes to the Company in writing,  within ten
(10) business days
<PAGE>
after receipt of a written request therefor,  such information specified in Item
507 of Regulation S-K under the Act or such other information as the Company may
reasonably request for use in connection with the Company Registration Statement
or Prospectus or preliminary  Prospectus included therein and in any application
to the NASD.  Holder as to which the  Company  Registration  Statement  is being
effected agrees to furnish  promptly to the Company all information  required to
be  disclosed  in order  to make all  information  previously  furnished  to the
Company by Holder not materially misleading.

         8. Anti-dilution Provision. The Exercise Price in effect from  time  to
time shall be,  subject to  adjustment in accordance with the provisions of this
Section 8.

                  (a)  Adjustments  for Stock  Splits and  Combinations.  If the
Company  shall at any time or from time to time after the date hereof,  effect a
stock split of the outstanding  Common Stock,  the applicable  Exercise Price in
effect immediately prior to the stock split shall be proportionately  decreased.
If the  Company  shall at any time or from time to time  after the date  hereof,
combine the outstanding shares of Common Stock, the applicable Exercise Price in
effect immediately prior to the combination shall be proportionately  increased.
Any  adjustments  under this  Section  8(a) shall be  effective  at the close of
business on the date the stock split or combination occurs.

                  (b) Adjustments for Certain  Dividends and  Distributions.  If
the Company shall at any time or from time after the date hereof,  make or issue
or set a record date for the  determination  of holders of Common Stock entitled
to receive a dividend or other  distribution  payable in shares of Common Stock,
then,  and in each event,  the applicable  Exercise Price in effect  immediately
prior to such event shall be  decreased  as of the time of such  issuance or, in
the event such a record date shall have been fixed,  as of the close of business
on such record date, by  multiplying,  as applicable,  the  applicable  Exercise
Price then in effect by a fraction;

                         (i) the numerator of which shall be the total number of
shares of Common Stock issued and outstanding immediately prior to the
<PAGE>
time of such issuance or the close of business on such record date;

and

                         (ii) the denominator of which shall be the total number
of shares of Common Stock issued and outstanding  immediately  prior to the time
of such issuance or the close of business on such record date plus the number of
shares of Common Stock issuable in payment of such dividend or distribution.

                  (c) Adjustment for Other Dividends and  Distributions.  If the
Company  shall at any time or from time to time after the date  hereof,  make or
issue or set a record  date for the  determination  of holders  of Common  Stock
entitled  to  receive a  dividend  or other  distribution  payable in other than
shares of Common Stock, then, and in each event, an appropriate  revision to the
Exercise Price shall be made and provision  shall be made (by adjustments of the
Exercise  Price or otherwise) so that the holder of this Note shall receive upon
conversions  thereof,  in  addition  to the  number of  shares  of Common  Stock
receivable  thereon,  the number of  securities  of the Company which they would
have received had this Note been converted into Common Stock on the date of such
event and had  thereafter,  during the period from the date of such event to and
including  the  date  hereof,   retained  such  securities  (together  with  any
distributions  payable  thereon during such period),  giving  application to all
adjustments  called for during such period  under this Section 8(c) with respect
to the rights of the holders of the Warrant.

                  (d)    Adjustments   for    Reclassification,    Exchange   or
Substitution.  If the Common Stock  issuable upon  conversion of this Warrant at
any time or from time to time after the date  hereof  shall be changed  into the
same or different number of shares of any class or classes of stock,  whether by
reclassification,  exchange,  substitution or otherwise  (other than by way of a
stock split or combination of shares or stock dividends provided for in Sections
8(a), (b) and (c), or a reorganization, merger, consolidation, or sale of assets
provided for in Section 8(e),  then, and in each event, an appropriate  revision
to the Exercise Price shall by made and provisions shall be made (by adjustments
of the Exercise  Price of  otherwise)  so that the holder of this Warrant  shall
have the right thereafter to convert such Warrant
<PAGE>
into the kind and amount of shares of stock and other securities receivable upon
reclassification,  exchange,  substitution  or other  change,  by holders of the
number of shares of  Common  Stock  into  which  such  Warrant  might  have been
converted immediately prior to such reclassification,  exchange, substitution or
other change, all subject to further adjustment as provided herein.

                  (e) Adjustments for Reorganization,  Merger,  Consolidation or
Sales of Assets. If at any time or from time to time after the date hereof there
shall be a capital  reorganization  of the Company (other than by way of a stock
split or combination of shares or stock dividends or distributions  provided for
in Section 8(a), (b), and (c), or a  reclassification,  exchange or substitution
of shares  provided for in Section  8(d),  or a merger or  consolidation  of the
Company with or into another  corporation,  or the sale of all or  substantially
all of the Company's properties or assets to any other person, then as a part of
such reorganization,  merger, consolidation, or sale, an appropriate revision to
the Exercise Price shall be made and provision  shall be made (by adjustments of
the Exercise  Price or  otherwise) so that the holder of this Warrant shall have
the right  thereafter to convert this Warrant into the kind and amount of shares
of stock and other  securities  or  property  of the  Company  or any  successor
corporation resulting from such reorganization,  merger, consolidation, or sale,
to which a holder of Common Stock  deliverable  upon  conversion  of such shares
would have been entitled upon such  reorganization,  merger,  consolidation,  or
sale,  to which a holder of Common Stock  deliverable  upon  conversion  of such
shares would have been entitled upon such reorganization, merger, consolidation,
or  sale.  In any  such  case,  appropriate  adjustment  shall  be  made  in the
application of the provisions of this Section 8(e) with respect to the rights of
the holders of this Warrant after the reorganization,  merger, consolidation, or
sale to the  end  that  the  provisions  of this  Section  8(e)  (including  any
adjustment in the applicable  conversion  ratio then in effect and the number of
shares of stock or other securities deliverable upon conversion of this Warrant)
shall be applied  after that event in as nearly an  equivalent  manner as may be
practicable.

         9. Laws  of  the  State  of Florida. This Warrant shall be governed by,
interpreted under and construed in all respects in
<PAGE>
accordance with, the laws of the State of Florida,  irrespective of the place of
domicile or residence of any party.

         10. Entire  Agreement and  Modification.  The Company and the Holder of
this Warrant  hereby  represent and warrant that this Warrant is intended to and
does contain and embody all of the understandings  and agreements,  both written
and oral,  of the  parties  hereto with  respect to the  subject  matter of this
Warrant,  and that there exists no oral agreement or  understanding,  express or
implied,  whereby the absolute,  final and unconditional character and nature of
this  Warrant  shall  be in  any  way  invalidated,  empowered  or  affected.  A
modification  or waiver of any of the terms,  conditions  or  provisions of this
Warrant  shall be effective  only if made in writing and executed  with the same
formality as this Warrant.

         11. Controlling Document. Notwithstanding anything contained herein, in
the event of conflict between any provision contained herein and those contained
in a certain note of even date simultaneously  delivered to Holder (the "Note"),
which Notes is incorporated herein by reference, the provisions contained in the
Note shall control.

         This  Warrant  will become  wholly void and of no effect and the rights
evidenced  hereby will terminate  unless  exercised in accordance with the terms
and  provisions  hereof at or before 5:00 p.m.,  Eastern Time, on the Expiration
Date.

corporation and is in good standing in each jurisdiction in which the conduct of
its business or the ownership of its assets requires such qualification.

(b)  Capitalization  of the  Company.  The  authorized,  issued and  outstanding
capital  stock  of  the  Company  is  described  on  the   Company's   Form  S-1

disclosed on the SEC Documents.

(c)  Authorization,  Execution  and Effect of  Agreements.  The  Company has all
requisite  corporate  power and  authority  to execute,  deliver and perform its
obligations under this Agreement and the Registration  Rights Agreement to issue
the Notes and the  Warrants  in the manner and for the purpose  contemplated  by
this Agreement,  and to execute,  deliver and perform its obligations under this
Agreement,  the  Notes,  the  Warrants  and the  Registration  Rights  Agreement
(collectively,  the  "Transaction  Documents")  and  all  other  agreements  and
instruments  heretofore or hereafter executed and delivered by it pursuant to or
in
<PAGE>
connection  with this  Agreement.  The execution and delivery of the Transaction
Documents and the consummation of the transactions contemplated hereby have been
duly authorized by all necessary corporate action of the Company. This Agreement
and the other  Transaction  Documents have each been duly executed and delivered
and  constitutes,  and upon  execution and delivery in accordance  herewith each
other  agreement or instrument  executed and  delivered by the Company  pursuant
hereto, including the Notes and Warrants, will constitute,  the legal, valid and
binding  obligations  of  the  Company,   enforceable  against  the  Company  in
accordance with their respective terms, subject in each such case, to applicable
bankruptcy,  insolvency,  reorganization  and similar laws affecting  creditors'
rights and remedies  generally  and subject,  as to  enforceability,  to general
principles  of  equity  (regardless  of  whether  enforcement  is  sought  in  a
proceeding at law or in equity).

(d)  Conflicting  Agreements  and Other  Matters.  The  execution,  delivery and
performance  by  the  Company  of  this  Agreement  and  the  other  Transaction
Documents,  and all other agreements and instruments  heretofore or hereafter to
be executed and delivered by the Company in connection with the  consummation of
the  transactions  contemplated  by this  Agreement  and the  other  Transaction
Documents,  and compliance by the Company with the terms and  provisions  hereof
and thereof  applicable to it,  including the issuance and sale of the Notes and
Warrants,  does not and will not (i) violate  any  provision  of any law,  rule,
regulation, order, writ, judgment, decree, administrative determination or award
having  applicability to the Company or any of the Subsidiaries or (ii) conflict
with or result in a breach of or constitute a default under the  Certificate  of
Incorporation  or By-Laws  of the  Company  or any of the  Subsidiaries,  or any
indenture  or loan or credit  agreement,  or any  other  material  agreement  or
instrument,  to which the  Company or any of the  Subsidiaries  is a party or by
which the Company or the Subsidiaries, or any of their respective properties are
bound or affected, and will not result in, or require the creation or imposition
of,  any lien upon or with  respect  to any of the  properties  now owned by the
Company or any of the  Subsidiaries or hereafter  acquired by the Company or any
of the Subsidiaries.

(e) Financial Information.  The (i) audited consolidated financial statements of
the  Company for the fiscal  year ended  September  30, 1997 as set forth in the
Company's Form 10-K/A filed with the SEC (the

the nine  months  ended  December  31, 1997 as set forth in the  Company's  Form

were  prepared in  accordance  with  generally  accepted  accounting  principles
("GAAP")  consistently  applied,  and fairly present the financial condition and
results of  operations  of the  Company  and the  Subsidiaries  for the  periods
indicated  therein;  provided,  that the unaudited  financial  statements do not
contain certain footnote  disclosures  required under GAAP for audited financial
statements and are subject to year end audit adjustments, none of which would be
material to an Investor's decision to purchase the Notes and Warrants.

(f) Litigation, Proceedings: Defaults. Except as disclosed on the SEC Reports or
on Schedule 3(f) hereto, there is no action,  suit,  proceeding or investigation
pending or, to the knowledge of the Company, threatened against or affecting the
Company or any of the Subsidiaries or any of their respective  properties before
or by any court,  governmental or regulatory authority (federal, state, local or
foreign)  which either (i) relates to or challenges  the  legality,  validity or
enforceability  of this  Agreement  or any other  document  or  agreement  to be
executed and delivered by the Company pursuant hereto or in connection herewith,
or (ii) if determined  adversely (A) would have a material adverse effect on the
condition (financial or otherwise),  properties,  assets, business or results of
operations  of the  Company or the  Subsidiaries,  when taken as a  consolidated
whole (a  "Material  Adverse  Effect")  after giving  effect to the  transaction
contemplated by this Agreement,  or (B) could  materially  impair the ability or
obligation of the Company or the Subsidiaries to perform fully on a timely basis
any  obligation  which it has or will have  under  this  Agreement  or the other
Transaction  Documents,  or  any  other  agreement  or  document  heretofore  or
hereafter  to be  executed  by the  Company  pursuant  hereto  or in  connection
herewith. Neither the Company nor any of the Subsidiaries is in violation of its
Certificate  of  Incorporation  or  By-Laws.  Neither the Company nor any of the
Subsidiaries  is (i) in  default  under or in  violation  of any other  material
agreement  or  instrument  to  which  it is a party or by which it or any of its
properties  are bound or  affected,  which  default  or  violation  would have a
Material Adverse Effect, (ii) in default with respect to any order of any court,
arbitrator or governmental body or subject to or party to any order of any court
or governmental
<PAGE>
authority  arising out of any action,  suit or  proceeding  under any statute or
other law respecting antitrust, monopoly, restraint of trade, unfair competition
or similar matters, or (iii) in violation of any statute,  rule or regulation of
any governmental authority material to its business.

(g) Governmental Consents, etc. No authorization,  consent,  approval,  license,
qualification  or  formal  exemption  from,  nor  any  filing,   declaration  or
registration with, any court, governmental agency or regulatory authority or any
securities exchange or any other person or entity (collectively  "Approvals") is
required  in  connection  with the  execution,  delivery or  performance  by the
Company of this Agreement.

(h) Use of Proceeds.  The first  $1,250,000  of the proceeds to the Company from
the sale of the Notes shall be used (i)  $250,000  for general  working  capital
purposes, and (ii) $1,000,000 to perform certain obligations under its June 1997
joint venture agreement with the Democratic  Republic of Sao Tome & Principe for
the  development of potential oil and gas reserves in the Gulf of Guinea of West
Africa (the "Sao Tome  Project"),  with the balance,  if any used by the Company
for additional  payments for general working  capital  purposes or to perform on
its obligations to the Sao Tome Project, as the Company so directs.

(i)  Accuracy  of all SEC  Public  Filings,  All SEC  Reports  furnished  to the
Investors or their  representatives and all other documents and reports filed by
or on behalf of the Company with the SEC, when filed, did not contain any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein or necessary in order to make the statements therein, in light of
the  circumstances  under which they were made, not misleading.  The Company and
each of its  Subsidiaries  has filed,  on a timely  basis,  all required  forms,
reports and  documents  with the SEC  required to be filed by it pursuant to the
Securities  Act and the  Securities  and Exchange  Act of 1934,  as amended (the
"Exchange  Act"),  all of which  complied at the time of filing in all  material
respects with all applicable requirements of the Securities Act and the Exchange
Act.

(j)  Absence of  Certain  Changes or  Events.  Since  June 30,  1997,  except as
contemplated  by this  Agreement,  disclosed on Schedule  3(j) hereto and made a
part hereof, or disclosed in any Company SEC Report filed

events having, individually or in the aggregate, a Material Adverse Effect, (ii)
any change by the Company in its  accounting  methods,  principles or practices,
(iii) any revaluation by the Company of any material asset  (including,  without
limitation, any writing down or writing up of the value of oil and gas reserves,
writing off of notes or accounts  receivable  or  reversing  of any  accruals or
reserves),  other than in the ordinary  course of business  consistent with past
practice, (iv) any entry by the Company or any Subsidiary into any commitment or
transaction  material  to the  Company  and the  Subsidiaries  taken as a whole,
except in the  ordinary  course  of  business  and  consistent  in all  material
respects with past practice, or (v) any declaration, setting aside or payment of
any dividend or  distribution  in respect of any capital stock of the Company or
any redemption, purchase or other acquisition of any of its securities.

(k) Absence of Litigation.  Except as disclosed in the Company SEC Reports or in
Schedule3(k)  annexed hereto and made a part hereof,  there is no claim, action,
proceeding or investigation  pending or, to the Company's knowledge,  threatened
against the Company or any  Subsidiary,  or any property or asset of the Company
or any  Subsidiary,  before any court,  arbitrator  or  Governmental  Authority,
which,  individually or when aggregated with other claims, actions,  proceedings
or  investigations  or  product  liability  claims,   actions,   proceedings  or
investigations   which  are   reasonably   likely  to  result   from  facts  and
circumstances  that  have  given  rise to such a claim,  action,  proceeding  or
investigation,  would have a Material  Adverse  Effect.  As of the date  hereof,
neither the Company nor any  Subsidiary nor any property or asset of the Company
or any Subsidiary is subject to any order, writ, judgment,  injunction,  decree,
determination  or award having,  individually  or in the  aggregate,  a Material
Adverse Effect.

(l) Labor Matters.  Except as set forth in Schedule 3(l) annexed hereto and made
a part hereof, with respect to employees of the Company:

         (i) to the best of the Company's knowledge, no senior executive or key
<PAGE>
         employee has any plans to terminate employment with the Company or  any
         of its Subsidiaries;

         (ii) there is no unfair labor practice charge or complaint  against the
Company  or any of its  Subsidiaries  pending  or, to the best of the  Company's
knowledge,  threatened  before the National Labor  Relations  Board or any other
comparable authority;

         (iii) there is no demand for recognition made by any labor organization
or petition for election  filed with the National Labor  Relations  Board or any
other comparable authority which, individually or in the aggregate, would have a
Material Adverse Effect;

         (iv) no grievance or any arbitration proceeding arising out of or under
collective  bargaining  agreements  is pending and, to the best of the Company's
knowledge,  no claims  therefor have been  threatened  other than  grievances or
arbitrations incurred in the ordinary course of business which,  individually or
in the aggregate, would not have a Adverse Effect; and

         (v)  there  is  no  litigation,  arbitration  proceeding,  governmental
investigation, administrative charge, citation or action of any kind pending or,
to the  knowledge  of the  Company  or any  of  its  Subsidiaries,  proposed  or
threatened  against the Company  relating to employment,  employment  practices,
terms and conditions of employment or wages and hours which,  individually or in
the  aggregate,  would have a Material  Adverse  Effect.  Except as disclosed in
Schedule  3(l),  none  of  the  Company  nor  any of its  Subsidiaries  has  any
collective   bargaining   relationship   or  duty  to  bargain  with  any  Labor
Organization  (as such term is  defined in Section  2(5) of the  National  Labor
Relations Act, as amended),  and none of the Company nor any of its Subsidiaries
has   recognized   any  labor   organization   as  the   collective   bargaining
representative of any of its employees.

(m) Title to and Sufficiency of Assets.  As of the date hereof,  the Company and
the  Subsidiaries  own,  and  as of  the  Closing  Date,  the  Company  and  the
Subsidiaries  will  own,  good  and  marketable  title  to all of  their  assets
constituting  personal property which is material to their business  (excluding,
for purposes of this sentence,  assets held under leases), free and clear of any
and all mortgages, liens, encumbrances,  charges, claims, restrictions, pledges,
security
<PAGE>
interests  or  impositions  (collectively,  "Liens")  except as set forth in the
Company SEC Reports or Schedule 3(m) annexed hereto and made a part hereof. Such
assets,  together with all assets held by the Company and the Subsidiaries under
leases,  include all tangible and intangible  personal  property,  contracts and
rights necessary or required for the operation of the businesses of the Company.
As of the date  hereof,  the Company  and the  Subsidiaries  own,  and as of the
Closing Date,  the Company and the  Subsidiaries  will own, good and  marketable
title to all of their real  estate,  including  oil and gas  reserves,  which is
material to such persons  (excluding,  for purposes of this sentence,  leases to
real  estate  and oil and gas  reserves),  free and clear of any and all  Liens,
except as set forth in the  Company  SEC  Reports or in  Schedule  3(m)  annexed
hereto or such other Liens which would not,  individually  or in the  aggregate,
have a Material Adverse Effect.  Such assets,  together with real estate and oil
and gas reserve  assets held by the Company and the  Subsidiaries  under leases,
are adequate for the operation of the  businesses  of the Company,  as presently
conducted.  The  leases to all real  estate and oil and gas  reserves  which are
material to the operations of the businesses of the Company and the Subsidiaries
are in full force and effect and no event has occurred  which,  with the passage
of time, the giving of notice,  or both,  would constitute a default or event of
default by the Company or any  Subsidiary  or, to the  knowledge of the Company,
any other person who is a party signatory  thereto,  other than such defaults or
events of default  which,  individually  or in the  aggregate,  would not have a
Material Adverse Effect.

Permits without any pending,  on-going or future obligation,  cost or liability,

non-compliance  would not,  individually  or in the  aggregate,  have a Material
Adverse Effect.

                  (B) Except as disclosed in Schedule  3(n-2) annexed hereto and
made a part  hereof,  neither the Company  nor any of the  Subsidiaries  has (I)

Company  Material  Adverse  Effect,  (II) any  knowledge  of the presence of any
Hazardous  Substances on, under,  emanating  from, or at any of the Company's or
any of the  Subsidiaries'  properties or any other property but arising from the
Company's  or  any  of  the  Subsidiaries'   current  or  former  properties  or
operations,  other than in a manner that would not result in a Material  Adverse
Effect,  or (III) any knowledge of nor has it received any written notice (x) of

annexed hereto.

(o)  Brokers.  No  broker,  finder or  investment  banker,  is  entitled  to any
brokerage,  finder's  or other fee or  commission  in  connection  with the this
Agreement and the transactions contemplated hereby, other than the following:

         International Holding Company
         Joseph Charles & Associates

(collectively the "IHC Group"). The Company has agreed to pay the IHC Group cash
compensation  not to exceed ten percent  (10.0%) of the face amount of the Notes
sold  pursuant  to this  Agreement  and to issue to the IHC  Group  notes not to
exceed three and one-half  percent  (3.5%) of the face amount of the total notes
sold to the Investors (the "Consultant Notes"),  which Consultant Notes shall be
on  substantially  the same terms and conditions as the Notes offered hereby and
warrants to purchase  shares of Company  Common  Stock in an amount equal to six
percent (6.0%) of the face amount of the Notes on  substantially  the same terms
and conditions as the Warrants offered hereby.

4.       REPRESENTATIONS AND WARRANTIES OF THE INVESTORS.

Each  Investor  hereby  separately  represents  and  warrants  to the Company as
follows (such  representations  and warranties being made separately and only to
the extent such representations and warranties relate to such Investor):

(a) Investigation;  Investment Representation.  Each Investor (i) possesses such
knowledge and experience in financial and business matters that it is capable of
evaluating  the  merits  and risks of its  investment  hereunder;  (ii) has been
afforded the opportunity to ask
<PAGE>
questions of, and receive  answers from,  the Company  concerning  the terms and
conditions  of its  investment,  the  transactions  contemplated  hereby and the
business and affairs of the Company;  (iii) has examined, to the extent it deems
appropriate,  all of the agreements  and documents  referred to herein or in the
schedules  hereto  and such  other  documents  that it has  requested;  and (iv)
understands  that the Notes,  the Warrants and the Warrant  Shares are not being
registered under the Securities Act of 1933, as amended,  on the ground that the
issuance  thereof  is  exempt  from  registration  under  Section  4(2)  of  the
Securities Act of 1933, as amended,  as a transaction by an issuer not involving
a public offering, and the Company's reliance on this exemption is predicated in
part on the Investors'  representations and warranties contained in this Section
4(a).  The  Investors  are acquiring the Notes and Warrants and will acquire the
Warrant Shares for their own account,  for investment purposes only and not with
a view to the sale or distribution thereof.

(b) Execution and Effect of Agreement. Each Investor has all necessary power and
authority  to  enter  into  this  Agreement  and  consummate  the   transactions
contemplated  hereby.  This Agreement  constitutes the legal,  valid and binding
obligation  of each  Investor,  enforceable  against each Investor in accordance
with its terms, subject to applicable  bankruptcy,  insolvency,  reorganization,
moratorium and similar laws affecting  creditors' rights and remedies  generally
and subject,  as to enforceability,  to general principles of equity (regardless
of whether enforcement is sought in a proceeding at law or in equity).

5.       COVENANTS.

As long as any of the Notes are outstanding,  the Company agrees that, unless it
first procures the written  consent to act otherwise of the holders of record of
66-2/3%  of the  outstanding  principal  amount  of the  Notes  of  record  then
outstanding, it will use its best efforts to cause each of its Subsidiaries to:

(a) Promptly pay all taxes (exclusive of income taxes imposed on the Investors),
fees and charges payable, or ruled to be payable, by any federal, state or local
authority,  in respect of this Agreement or the execution,  delivery or issuance
of the  Notes or  Warrant  Shares by reason  of any now  existing  or  hereafter
enacted federal, state or
<PAGE>
local statute or ordinance,  and indemnify and hold the Investors  harmless from
and against  all  liabilities  with  respect to or in  connection  with any such
taxes, fees or charges.

(b) Maintain  their  corporate  existence  and right to carry on business,  duly
procure  all  necessary  renewals  and  extensions  thereof,  and use their best
efforts to  maintain,  preserve and renew all  necessary  or  desirable  rights,
powers, privileges and franchises owned by them.

(c)  Promptly  notify  the  Investors  of any  material  adverse  change  in the
condition (financial or otherwise),  properties,  assets, business or results of
operations of the Company or any of the Subsidiaries.

(d) Not cause,  suffer or permit any  liquidation,  winding up or dissolution of
the Company or the Subsidiaries.

(e)  Maintain  and cause the  Subsidiaries  to  maintain a system of  accounting
established and  administered in accordance with generally  accepted  accounting
principles.

(f) Comply with all of the covenants  and  agreements on the part of the Company
to be  performed  under  the  terms of the  Notes,  the  Warrants  and the other
Transaction Documents.

Kingsbridge  Capital  Limited and the Company dated as of March 23, 1998 and not
enter into a similar agreement with Kingsbridge  Capital Limited while the Notes
are outstanding.

6.       FINANCIAL STATEMENTS; INSPECTION; NON-PUBLIC INFORMATION.

(a) The Company will furnish to each Investor (and their permitted  transferees,
successors and assigns),  as long as such Investor owns any of the Notes, copies
of all Form 10-K Annual Report and Form 10-Q Quarterly  Financial  Reports filed
by the Company, with the SEC.

(b) The Company will,  subject to execution of appropriate  confidentiality  and
non-  disclosure  agreements,  permit the Investors,  as long as they own Notes,
shares of Common Stock  issuable upon  conversion of the Notes (the  "Conversion
Shares"), Warrants or shares
<PAGE>
of Common Stock  issuable upon exercise of the Warrants (the "Warrant  Shares"),
or any  authorized  representative  designated  by the  Investors,  to visit and
inspect at the  Investors'  expense any of the properties of the Company and the
Subsidiaries, and to discuss its affairs, finances and accounts with officers of
the Company,  all at such  reasonable  times and as often as the  Investors  may
reasonably request.

(c) The  Company  in no  event  shall  disclose  non-public  information  to the
Investors,  advisors to or  representatives  of the  Investors  unless  prior to
disclosure of such information the Company marks such information as 'Non-Public
Information  -  Confidential"  and provides  the  Investors,  such  advisors and
representatives with a reasonable opportunity to accept or refuse to accept such
non-public  information for review.  Nothing herein shall require the Company to
disclose non-public information to the Investors or their respective advisors or
representatives,  and  the  Company  represents  that it  does  not  disseminate
non-public  information  to any Investors who purchase stock in the Company in a
public offering, to money managers or to securities analysts; provided, however,
that  notwithstanding  anything  herein to the  contrary,  the Company  will, as
hereinabove provided, notify immediately the advisors and representatives of the
Investors  and,  if any,  underwriters,  of any  event or the  existence  of any
circumstance   (without  any  obligation  to  disclose  the  specific  event  or
circumstance)  of which it becomes aware,  constituting  non-public  information
(whether or not requested of the Company  specifically  or generally  during the
course of due diligence by such persons or entities), which, if not disclosed in
the  Prospectus  included  in  the  Registration  Statement,  would  cause  such

(e) the National  Quotation Bureau,  Inc. for quotes on the Electronic  Bulletin

consecutive  trading days  immediately  preceding the Issuance Date, the date of

the case may be.

(d) Adjustments of Conversion Price. The Conversion Price in effect from time to

of the  outstanding  Common Stock,  the  applicable  Conversion  Price in effect
immediately prior to the stock split shall be  proportionately  decreased (or in

time or from time to time  after the  Issuance  Date,  combine  the  outstanding
shares of Common Stock, the applicable  Conversion  Price in effect  immediately
prior to the combination  shall be  proportionately  increased.  Any adjustments
under this  Section  5(d)(i)  shall be effective at the close of business on the

prior to such event shall be  decreased  as of the time of such  issuance or, in
the event such a record date shall have been fixed,  as of the close of business
on such record date, by multiplying,  as applicable,  the applicable  Conversion
Price then in effect by a fraction;

                  (A) the numerator of which shall be the total number of shares
of Common Stock  issued and  outstanding  immediately  prior to the time of such

shall at any time or from time to time after the Issuance Date, make or issue or
set a record date for the  determination  of holders of Common Stock entitled to
receive a dividend or other distribution  payable in other than shares of Common
Stock, then, and in each event, an appropriate  revision to the Conversion Price
shall be made and  provision  shall be made (by  adjustments  of the  Conversion
Price  or  otherwise)  so that  the  holder  of this  Note  shall  receive  upon
conversions  thereof,  in  addition  to the  number of  shares  of Common  Stock
receivable  thereon,  the number of  securities  of the Company which they would
have received had this Note been converted into Common Stock on the date of such
event and had  thereafter,  during the period from the date of such event to and
including the  Conversion  Date,  retained such  securities  (together  with any
distributions  payable  thereon during such period),  giving  application to all
adjustments  called for during such period  under this  Section  5(d)(iii)  with
respect to the rights of the holders of the Note.

         (iv) Adjustments for Reclassification, Exchange or Substitution. If the
Common Stock  issuable upon  conversion of this Note at any time or from time to
time after the Issuance Date shall be changed into the same or different  number
of  shares of any  class or  classes  of  stock,  whether  by  reclassification,
exchange,  substitution  or  otherwise  (other  than by way of a stock  split or
combination of shares or stock dividends provided for in Sections 5(d)(i),  (ii)
and  (iii),  or a  reorganization,  merger,  consolidation,  or sale  of  assets
provided  for in Section  5(d)(v)),  then,  and in each  event,  an  appropriate
revision to the Conversion  Price shall by made and provisions shall be made (by
adjustments  of the  Conversion  Price of  otherwise) so that the holder of this
Note shall  have the right  thereafter  to  convert  such Note into the kind and
amount of shares of stock and other securities receivable upon reclassification,
exchange,  substitution  or other change,  by holders of the number of shares of
Common Stock into which such Note might have been converted immediately prior to
such  reclassification,  exchange,  substitution or other change, all subject to
further adjustment as provided herein.

         (v) Adjustments for Reorganization,  Merger,  Consolidation or Sales of
Assets.  If at any time or from time to time after the Issuance Date there shall
be a capital  reorganization  of the Company (other than by way of a stock split
or combination  of shares or stock  dividends or  distributions  provided for in
Section 5(d)(i), (ii) and (iii), or a reclassification, exchange or substitution
of shares
<PAGE>
provided for in Section  5(d)(iv)),  or a merger or consolidation of the Company
with or into another corporation, or the sale of all or substantially all of the
Company's  properties  or  assets to any  other  person,  then as a part of such
reorganization,  merger, consolidation,  or sale, an appropriate revision to the
Conversion  Price shall be made and provision  shall be made (by  adjustments of
the  Conversion  Price or  otherwise) so that the holder of this Note shall have
the right  thereafter to convert this Note into the kind and amount of shares of
stock  and  other  securities  or  property  of the  Company  or  any  successor
corporation resulting from such reorganization,  merger, consolidation, or sale,
to which a holder of Common Stock  deliverable  upon  conversion  of such shares
would have been entitled upon such  reorganization,  merger,  consolidation,  or
sale,  to which a holder of Common Stock  deliverable  upon  conversion  of such
shares would have been entitled upon such reorganization, merger, consolidation,
or  sale.  In any  such  case,  appropriate  adjustment  shall  be  made  in the
application of the provisions of this Section 5(d)(v) with respect to the rights
of the holders of this Note after the reorganization,  merger, consolidation, or
sale to the end that the  provisions  of this  Section  5(d)(v)  (including  any
adjustment in the applicable  Conversion  Ratio then in effect and the number of
shares of stock or other  securities  deliverable  upon conversion of this Note)
shall be applied  after that event in as nearly an  equivalent  manner as may be
practicable.

         (vi)   Adjustments   after   Registration   Statement   is   Effective.
Notwithstanding  any  other  provision  contained  in  this  Section  5(d),  the
Conversion Price shall be adjusted following the effective date of the Company's

five (5) days trading immediately preceding the date of the Conversation Notice;
and

                  (B) for  conversions  beginning  120 days after the  Effective

five (5) days trading immediately preceding the date of the Conversion Notice.

Incorporation or through any reorganization, transfer
<PAGE>
of assets,  consolidation,  merger, dissolution,  issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed  hereunder  by the Company,  but

other  securities  or  property  which at the time  would be  received  upon the
conversion of such Note. Notwithstanding the foregoing, the Company shall not be
obligated to deliver a  certificate  unless such  certificate  would  reflect an
increase or decrease of at least one percent of such adjusted amount.

written  consent  of persons  holding  66-2/3 % or more in  aggregate  principal
amount  of the  Notes  of the  Company  issued  under  the  Securities  Purchase
Agreement (including the Payee), the Payee and other holders of any of the Notes
at the time  outstanding  may  proceed to protect and enforce the rights of such
holder  by an action at law,  suit in  equity or other  appropriate  proceeding,
whether for the specific  performance of any agreement  contained herein, or for
an injunction  against a violation of any of the terms hereof,  or in aid of the
exercise  of any power  granted  hereby  or by law.  In the event of an Event of
Default,  the  Company  agrees to pay to the  holder  of this Note such  further
amount as shall be  sufficient  to cover  the cost and  expense  of  collection,
including,  without  limitation,  reasonable  attorneys'  fees and  expenses and
reasonable  costs of  investigation.  If the  holder of any Note  shall give any
notice or take any action in  respect of a claimed  default,  the  Company  will
forthwith  give  written  notice  thereof to the holder of this Note at the time
outstanding  describing  the  notice or  action  and the  nature of the  claimed
default.  No course of  dealing  and no delay on the part of the  holder of this
Note or the holder of any other Note in  exercising  any right,  power or remedy
shall operate as a waiver thereof or otherwise  prejudice such holder's  rights,
powers and remedies.  No right, power or remedy conferred hereby upon the holder
hereof shall be exclusive of any other right, power or remedy referred to herein
nor now or hereafter available at law, in equity, by statute or otherwise.

8.     WAIVER OF PRESENTMENT; MAXIMUM RATE OF INTEREST

(a) The Company and each surety,  endorser,  and guarantor or other party liable
for the payment of any sums of money  payable on this Note  severally  waive all
demands for payment,  presentations for payment, notices of dishonor, notices of
intention to accelerate maturity, notices of acceleration of maturity, protests,
and notices of protest, to the extent required by law.

(b) It is  expressly  stipulated  and agreed to be the intent of the Company and
the  Holders  of this  Note at all  times  to  comply  with the  applicable  law
governing  the maximum  rate of interest  payable on or in  connection  with all
indebtedness and transactions hereunder (or applicable United States federal law
to the extent  that it permits  holders of this Note to  contract  for,  charge,
take, reserve or receive a greater amount of interest). If the applicable law is
ever  judicially  interpreted  so as to render  usurious  any amount of money or
other  consideration  called for hereunder,  or contracted for, charged,  taken,
reserved  or  received  with  respect  to any loan or advance  hereunder,  or if
acceleration of the maturity of the Note or the indebtedness hereunder or if any
prepayment by the Company  results in the Company's  having paid any interest in
excess of that  permitted by law, then it is the Company's and Holders'  express
intent that all excess cash amounts theretofore  collected by holder by credited
on the principal balance of this Note (or if this Note has been or would thereby
be paid in full,  refunded  to the  Company),  and the  provisions  of this Note
immediately be deemed reformed and the amounts thereafter  collectible hereunder
reduced,  without the necessity of the  execution of any new document,  so as to
comply with the applicable  law, but so as to permit the recovery of the fullest
amount otherwise called for hereunder.  The right to accelerate maturity of this
Note  does not  include  the  right to  accelerate  any  interest  which has not
otherwise accrued on the date of such  acceleration,  and Holder does not intend
to collect any unearned interest in the event of acceleration.

9.       NOTICES.

All notices,  requests, demands or other communications under this Note shall be
given in the same manner as provided in the Securities Purchase Agreement.

10.      GOVERNING LAW;  RESOLUTION OF DISPUTES

(a) This Note shall be governed by, and construed and  interpreted in accordance
with,  the laws of the State of New York,  without  giving effect to conflict of
law principles.
<PAGE>
(b) Any dispute  regarding the  interpretation or application of this Note which
cannot be settled among the parties shall be resolved in Austin, Texas final and
binding  arbitration in accordance with the then obtaining rules of the American
Arbitration Association. There shall be appointed three arbitrators, one of whom
shall be  selected  by the  Company,  the  second by the Holder and the third by
mutual agreement of the parties or by the American Arbitration Association.  The
decision of the  arbitrators  shall be final and upon the Holder and the Company
and may be enforced by the prevailing party or parties in any court of competent
jurisdiction. Each party shall bear their own costs of the arbitration and shall
share equally the costs of the arbitrators.

11.      SUBORDINATION TO SENIOR DEBT.

(a) Payment of the  principal  of and  interest on this Note and all other Notes
issued under the Securities  Purchase  Agreement is subordinated,  to the extent
and in the manner provided  herein,  to the prior payment of all indebtedness of
the Company and/or all Subsidiaries of the Company,  for money borrowed or other
obligations which is now or may hereafter be owed (collectively,  "Senior Debt")
to any bank,  commercial  finance company,  factor,  insurance  company or other
institution the lending activities are regulated by law (individually, a "Senior
Lender" and collectively,  "Senior Lenders"), which may, hereafter on any one or
more  occasions  provide  financing  to the Company or any of its  Subsidiaries,
secured by liens on any of the assets and  properties of the Company  and/or any
of  its  Subsidiaries   (individually   and   collectively,   an  "Institutional
Borrower").

(b)  Upon  any  payment  or   distribution   of  assets  or  securities  of  the
Institutional Borrower, as the case may be, of any kind or character, whether in
cash,  property or  securities,  upon any  dissolution or winding up or total or
partial  liquidation or reorganization of the  Institutional  Borrower,  whether
voluntary or  involuntary or in bankruptcy,  insolvency,  receivership  or other
proceedings,  all amounts  payable under Senior Debt shall first be paid in full
in cash, or payment provided for in cash or cash equivalents,  before the holder
hereof  shall be entitled to receive any payment on account of  principal  of or
interest  on this Note.  Before  any  payment  may be made by the  Institutional
Borrower of the principal of or interest on this Note upon any such  dissolution
or winding up or liquidation or  reorganization,  any payment or distribution of
assets or  securities  of the  Institutional  Borrower of any kind or character,
whether in cash,  property or  securities,  to which the holder  hereof would be
entitled,  except for the  provisions  of this  Section 11, shall be made by the
Institutional Borrower or by any receiver, trustee in bankruptcy,
<PAGE>
liquidating trustee,  agent or other person making such payment or distribution,
directly to the holders of Senior  Debt or their  representatives  to the extent
necessary  to pay all  such  Senior  Debt in full  after  giving  effect  to any
concurrent payment or distribution to the holders of such Senior Debt.

(c) Upon the happening of any default in payment of the principal of or interest
on any Senior Debt, then, unless and until such default shall have been cured or
waived or shall have  ceased to exist,  no direct or  indirect  payment in cash,
property or securities,  by set-off or otherwise,  shall be made or agreed to be
made by the Institutional Borrower on account of the principal of or interest on
this Note.

(d) Upon the  happening of an event of default  (other than under  circumstances
when the terms of Section 11(c) above are applicable) with respect to any Senior
Debt  pursuant to which the holder  thereof is entitled  under the terms of such
Senior Debt to accelerate the maturity thereof,  and upon written notice thereof
given to each of the Institutional  Borrower and the holder of this Note by such
holder of Senior Debt ("Payment  Notice"),  then, unless and until such event of
default shall have been cured or waived or shall have ceased to exist, no action
shall or may be taken for  collection  of any  amounts  under this Note,  and no
direct or  indirect  payment  in cash,  property  or  securities,  by set-off or
otherwise,  shall be made or agreed to be made by the Institutional  Borrower an
account of the  principal of or interest on this Note until such Senior Debt has
been paid in full accordance with its terms.

(e) In the event than,  notwithstanding  the  provisions of this Section 11, any
payment shall be made on account of the principal of or interest on this Note in
contravention  of such  provisions,  then  such  payment  shall  be held for the
benefit of, and shall be paid over and  delivered to, the holders of such Senior
Debt  remaining  unpaid to the extent  necessary to pay in full the principal of
and  interest  on such  Senior Debt in  accordance  with its terms after  giving
effect to any concurrent  payment or  distribution to the holders of such Senior
Debt.

(f) Nothing  contained in this Section 11 shall (i) impair the conversion rights
of the holder hereof referred to in Section 5 above, (ii) impair, as between the
Company and the holder of this Note,  the  obligation  of the Company,  which is
absolute and  unconditional,  to pay to the holder hereof principal and interest
as the same shall become due and  payable,  or (iii)  prevent the holder  hereof
from exercising all rights,  powers and remedies  otherwise  provided herein, in
the  Securities  Purchase  Agreement  or by  applicable  law, all subject to the
express limitations provided herein.
<PAGE>
(g) Upon the occurrence of an Event of Default, if any Senior Debt shall then be
outstanding,  no  acceleration  of the  maturity of this Note shall be effective
until the earlier of (i) ten (10) days shall have passed  following  the date of
delivery to the  Institutional  Borrower by a Senior Lender(s) of written notice
of acceleration of any Senior Debt, or (ii) the maturity of any then outstanding
Senior  Debt  shall have been  accelerated  by reason of a default  hereon.  The
Company may pay the holder  hereof any  defaulted  payment and all other amounts
due following any such acceleration of the maturity of this Note if this Section
11 would not prohibit such payment to be made at that time.

(h) Upon  payment  in full of all Senior  Debt,  the Payee of this Note shall be
subrogated  to the rights of the holder or holders of Senior Debt to receive all
payments or  distributions  applicable on Senior Debt to the extent of the prior
application  thereto of moneys or other assets which would have been received in
respect  of this  Note,  but  for  these  subordination  provisions,  until  the
principal of, and interest on, this Note shall have been paid in full.

(i) The Payee, by accepting this Note (A) shall be bound by all of the foregoing
subordination  provisions;  and (B)  agrees  expressly  for the  benefit  of the
present  and  future  holders  of Senior  Debt that this Note is  subject to the
foregoing subordination provisions.

(j) The  foregoing  subordination  provisions  shall be for the  benefit  of all
holders of Senior Debt from time to time  outstanding,  and each of such holders
may proceed to enforce such provisions either directly against the holder hereof
or in any other manner provided by law.

(k)  Notwithstanding  anything to the contrary set forth in this Section 11, the
interest  of the  Holder of this Note (as  specified  in  Section  12 hereof) is
subject and subordinated  only to the prior first lien and security  interest of
any holder of Senior Debt of the Company,  unless otherwise  expressly consented
to in writing by the Payee.

12.      SUCCESSORS AND ASSIGNS.

This Note shall be binding  upon and inure to the benefit of the Company and the
holder hereof and their respective  successors and assigns;  provided,  however,
that the  Company may not  transfer  or assign any of its rights or  obligations
hereunder without the prior written consent of the holder hereof.

IN WITNESS WHEREOF,  the Company has caused this Note to be executed by its duly
authorized officers as of the date first set forth above.

           WARRANT TO PURCHASE SHARES OF COMMON STOCK OF ENVIRONMENTAL
                         REMEDIATION HOLDING CORPORATION

________________ Shares As of June 24, 1998                   New York, New York
 
THIS  WARRANT  AND THE SHARES OF COMMON  STOCK  ISSUABLE  UPON  EXERCISE OF THIS
WARRANT HAVE NOT BEEN  REGISTERED  UNDER THE  SECURITIES ACT OF 1933, AS AMENDED
(THE  "SECURITIES  ACT") AND SUCH SECURITIES MAY NOT BE SOLD,  OFFERED FOR SALE,
PLEDGED OR  HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE  REGISTRATION  STATEMENT
UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.

                       VOID AFTER 5:00 P.M., NEW YORK TIME
                                ON June 23, 2003

THIS  CERTIFIES  THAT  for  value  received,  _______________________,  or their
registered   permitted  assigns  (sometimes   hereinafter  referred  to  as  the
"Holder"),  may subscribe for and purchase,  subject to the terms and conditions
hereof,  from  ENVIRONMENTAL   REMEDIATION  HOLDING   CORPORATION,   a  Colorado
corporation  (the  ("Company"),  an amount  of  shares  of  common  stock of the
Company,  par value $0.0001 per share (the "Common Stock") equal to 12.4% of the
amount of the Note, as set forth and defined in Section 1(e) hereto, at any time
during the period  (the  "Exercise  Period")  from 9:00 am. New York Time on the
Effective Date (as such term is hereinafter defined) and ending at 5:00 p.m. New
York Time, on June 23, 2003 (the "Expiration  Date"), at an exercise price equal
to an amount per share to be determined by formula (the "Exercise Price");  such
Exercise  Price  being  120% of the  average  of the  Closing  Bid  Price of the
Company's Common Stock for each of the five (5) consecutive  trading days ending
on the day prior to the issuance  date set forth above.  The number of shares of
Common Stock  purchasable  upon  exercise of this Warrant (the  "Warrant"),  the
Exercise  Price,  and the kind of securities  purchasable  upon exercise of this
Warrant, shall be subject to adjustment from time to time upon the occurrence of
certain events as set forth below.  The shares of Common Stock  receivable  upon
exercise of this Warrant,  as adjusted from time to time, are sometimes referred
to hereinafter as "Exercise Shares."

1.       Exercise Price and Expiration.

(a) This  Warrant may be  exercised  in whole or in part on any Business Day (as
such term is  hereinafter  defined) at any time during the Exercise  Period upon
surrender to the  Company,  at its address for notices set forth in Section 9 of
this  Warrant  (or at such other  office of the  Company,  if any, or such other
office  of the  Company's  duly  authorized  agent for such  purpose,  as may be
maintained  by the Company for such purpose and so  designated by the Company by
written  notice  to the  Holders  prior  to such  exercise),  together  with the
following:  (i) a duly completed and executed Notice of Warrant  Exercise in the
form  annexed  hereto,  and (ii)  payment  of the full  Exercise  Price for this
Warrant or the portion thereof then being exercised. This Warrant and all rights
and options hereunder shall expire on, and shall be immediately  wholly null and
void  to  the  extent  the  Warrant  is  not  properly  exercised  prior  to the
Expiration.  As used in this Warrant the term "Business Day" shall mean the time
period  between  9:00 a.m. New York,  New York Time and 5:00 p.m. New York,  New
York  Time on any day other  than any  Saturday,  Sunday,  or other day on which
commercial  banks in New York, New York are required or are authorized by law to
close.

(b) Such  Exercise  Price shall be paid in lawful money of the United  States of
America by bank  cashier's  check or by wire transfer of  immediately  available
funds to such account as shall have been designated in writing by the Company to
the Holders from time to time.

(c) The Company shall,  immediately upon receipt of a notice of exercise,  issue
and deliver to or upon the order of such Holder, against delivery of the Warrant
and payment of the Exercise Price, a certificate or certificates  for the number
of  shares of Common  Stock to which  such  Holder  shall be  entitled  and such
certificate or certificates shall not bear any restrictive legend; provided, (i)
the Common Stock evidenced thereby are sold pursuant to an effective
<PAGE>
registration  statement  under the Securities  Act, (ii) the Holder provides the
Company with an opinion of counsel  reasonably  acceptable to the Company to the
effect that a public sale of such shares may be made without  registration under
the Securities  Act, or (iii) such holder  provides the Company with  reasonable
assurance that such shares can be sold free of any  limitations  imposed by Rule
144, promulgated under the Securities Act. The Company shall cause such issuance
and delivery to be effected  within three (3) business  days and shall  transmit
the  certificates by messenger or overnight  delivery  service,  or via the DWAC
system, to reach the address designated by such Holder within three (3) business
days after the receipt of such  notice.  The  Holders  shall be deemed to be the
Holders of record of the shares of Common  Stock  issuable  upon such  exercise,
notwithstanding  that the stock  transfer  books of the  Company  shall  then be
closed or that  certificates  representing such shares of Common Stock shall not
then be  actually  delivered  to the  Holders.  If, at the time this  Warrant is
exercised,  a  registration  statement  under the  Securities Act is not then in
effect to register the Exercise  Shares under said  Securities  Act the Exercise
Shares  issuable upon  exercise of this Warrant  (together  with any  applicable
state securities law registrations), the Company may require the Holders to make
such  representations,  and may place such legends on certificates  representing
the Exercise Shares, as may be reasonably  required in the opinion of counsel to
the  Company  to  permit  the  Exercise   Shares  to  be  issued   without  such
registration,  unless the  Company  receives  an  opinion of counsel  reasonably
satisfactory to counsel to the Company to the effect that said securities may be
freely traded without registration under the Securities Act.

(d) If the Holders shall  exercise this Warrant with respect to less than all of
the Exercise Shares that may then be purchased under this Warrant,  having taken
into  account any prior  exercise of the  Warrant,  the Company  shall  promptly
execute and deliver to the Holders a new warrant in the form of this Warrant for
the balance of such Exercise Shares.

(e) For purposes of the Warrant,  the term "Effective  Date" shall mean the date
that the  holder  of this  Warrant  shall  have  purchased  from the  Company  $
____________  principal  amount of the Company's 5.5%  convertible note due June
23, 2000 (the "Note") pursuant to the Securities Purchase Agreement, dated as of
June 24, 1998 (the "Securities  Purchase  Agreement").  Unless otherwise defined
herein,  all capitalized  terms used in this Warrant shall have the same meaning
as is defined in the Securities Purchase Agreement or in the Note.

2.     Anti-dilution.

If the Company shall

(a) pay a dividend or make a distribution to holders of shares of Company Common
Stock in the form of additional shares of Common Stock,

(b) subdivide or split or reverse split or consolidate the outstanding shares of
Common Stock into a larger or smaller number of shares, or

(c) effect a  recapitalization  which shall reclassify the outstanding shares of
Common Stock into one or more classes of common stock,

the number of shares of Common Stock  issuable upon exercise of this Warrant and
the Exercise Price shall be equitably and proportionately  adjusted  immediately
following  the  occurrence  of any such event,  and the Holder of record of this
Warrant  shall  be given  notice  of the same at such  Holder's  address  in the
Company's  books and records.  An adjustment made pursuant to this Section shall
become effective  immediately after the record date in the case of a dividend or
distribution  and  immediately  after  the  effective  date  in  the  case  of a
subdivision,  split,  combination or reclassification;  provided, if such record
date  shall  have been  fixed  and such  dividend  is not fully  paid or if such
distribution  is not fully made on the date fixed  therefor,  the exercise price
shall be recomputed  accordingly as of the close of business on such record date
and thereafter  such exercise  price in effect shall be as adjusted  pursuant to
this Section as of the time of actual payment of such dividend or distribution.

3.      Reorganization and Asset Sales.

If any capital  reorganization or  reclassification  of the capital stock of the
Company, or any consolidation or merger of the Company with another corporation,
or the sale of all or  substantially  all of the  assets  or  properties  of the
Company  to  another  corporation,  shall be  effected  in such a manner so that
holders of Company Common Stock shall be entitled to receive  stock,  securities
or assets with respect to or in exchange for Company Common Stock,  then, and in
such event, the following provisions shall apply:
<PAGE>
(a) Not more than 90 or less than 30 days prior to the  consummation of any such
reorganization,  reclassification,  consolidation, merger or sale (collectively,
"Reorganization  Transactions"),  the  Company  shall  notify the Holders of the
Reorganization  Transaction  (at the  same  time  notice  of same  shall be made
generally  available to other holders of Company  Common  Stock),  describing in
such notice in reasonable detail the terms of the Reorganization Transaction and
the stock,  securities  or assets to be received  with respect to or in exchange
for Common Stock of the Company.  In the event the Holders  exercise the Warrant
prior  to  or  simultaneous   with  the   consummation  of  the   Reorganization
Transaction,  the  Holders  shall be entitled to receive  stock,  securities  or
assets with  respect to or in exchange for Common Stock on the same basis as the
other  holders of  Company  Common  Stock  participating  in the  Reorganization
Transaction.

(b) The  Company  shall not effect any such  Reorganization  Transaction  unless
prior  to  or  simultaneous  with  the  consummation   thereof,   the  successor
corporation  (if other than the  Company)  resulting  therefrom  shall assume by
written  instrument  executed  and made  available  to the  Holders  at the last
address of the Holders appearing on the books of the Company,  the obligation to
deliver to the  Holders  such  shares of stock,  securities  or  assets,  as, in
accordance  with the  foregoing  provisions,  the  Holders  may be  entitled  to
receive, and all other liabilities and obligations of the Company hereunder.  In
the event the Holders of this Warrant shall not exercise the Warrant prior to or
simultaneous with consummation of the Reorganization  Transaction,  such Holders
shall be entitled to receive a warrant to purchase common stock in the successor
corporation (if other than the Company) which shall be appropriately adjusted as
to exercise price, number of shares which may be purchased  thereunder and other
terms, so as to equitably reflect the Reorganization Transaction and entitle the
Holder to  purchase  that  number of  shares  of common  stock of the  successor
corporation equivalent in value to the consideration that such Holder would have
received   had  Holder   exercised   this  Warrant   immediately   prior  to  or
simultaneously with such Reorganization Transaction.

(c) If a  purchase,  tender or  exchange  offer is made to and  accepted  by the
holders of more than 50 percent of the outstanding shares of Common Stock of the
Company,  the Company shall,  prior to the  consummation  of any  consolidation,
merger or sale to or with the person, firm or corporation having made such offer
or any  affiliate  of such  person,  firm or  corporation,  give the  Holders  a
reasonable  opportunity  of not less than 10 days to elect to  receive  upon the
exercise of this Warrant,  either the stock,  securities or assets then issuable
with  respect to the Common  Stock of the  Company or the stock,  securities  or
assets,  or the  equivalent,  issued to previous  holders of the Common Stock in
accordance with such purchase tender or exchange offer.

4.       Notice of Adjustment.

Whenever  the  Exercise  and the number of  Exercise  Shares  issuable  upon the
exercise of this Warrant shall be adjusted as herein provided,  or the rights of
the Holders shall change by reason of other events specified herein, the Company
shall compute the adjusted  Exercise  Price and the number of adjusted  Exercise
Shares in accordance with the provisions  hereof and shall prepare a certificate
signed by its Chief Executive Officer, or its President,  or its Chief Financial
Officer,  setting forth the adjusted  Exercise Price and the adjusted  number of
Exercise  Shares  issuable upon the exercise of this Warrant or  specifying  the
other  shares of stock,  securities,  or assets  receivable  as a result of such
changes in rights,  and showing in reasonable  detail the facts and calculations
upon which such adjustments or other changes are based. The Company shall caused
to be mailed to the Holders copies of such officer's certificate together with a
notice  stating  that the  Exercise  Price  and the  number of  Exercise  Shares
purchasable upon exercise of this Warrant have been adjusted and setting,  forth
the  adjusted  Exercise  Price  and  the  adjusted  number  of  Exercise  Shares
purchasable upon the exercise of this Warrant.

5.       Piggyback Registration Rights.

(a) At any  time  that  the  Company  proposes  to file a  Company  registration
statement  on Form S-1 or any  other  appropriate  registration  form  under the
Securities Act of 1933, as amended (the "Registrations  Statement"),  either for
its own account or for the account of a stockholder or stockholders, the Company
shall  give the  Holder  written  notice  of its  intention  to do so and of the
intended  method of sale (the  "Registration  Notice")  within a reasonable time
prior to the  anticipated  filing date of the Company's  Registration  Statement
effecting such Company  registration.  Holder may request inclusion of any which
are issued as with restrictions on transferability  ("Restricted Securities") in
such Registration
<PAGE>
Statement by  delivering  to the Company,  within ten (10)  Business  Days after
receipt of the Registration  Notice,  a written notice (the "Piggyback  Notice")
stating the number of  Restricted  Securities  proposed to be included  and that
such shares are to be included  in any  underwriting  only on the same terms and
conditions  as  the  shares  of  Common  Stock   otherwise  being  sold  through
underwriters under such Company  Registration  Statement.  The Company shall use
its best efforts to cause all Restricted  Securities  specified in the Piggyback
Notice to be  included  in the Company  Registration  Statement  and any related
offering,  all to the extent  requisite  to permit the sale by the Holder of its
Restricted  Securities in accordance  with the method of sale  applicable to the
other shares of Common Stock  included in such Company  Registration  Statement;
provided,  however,  that if, at any time  after  giving  written  notice of its
intention  to register any  securities  and prior to the  effective  date of the
Company Registration  Statement filed in connection with such registration,  the
Company shall determine for any reason not to register or to delay  registration
of Holder's  Restricted  Securities,  the Company  may,  at its  election,  give
written notice of such determination to Holder and, thereupon:

         (i) in the ease of a determination  not to register,  shall be relieved
of its obligation to register Holder's Restricted  Securities in connection with
such registration, and

         (ii) in the case of a delay in registering, shall be permitted to delay
registering  Holder's Restricted  Securities for the same period as the delay in
registering such other securities.

(b) The  Company's  obligation to include  Restricted  Securities in a Company's
Registration  Statement  pursuant  to  Section  7(a)  shall  be  subject  to the
following limitations:

         (i) The  Company  shall not be  obligated  to  include  any  Restricted
Securities in a registration statement filed on Form S-4, Form S-8 or such other
similar successor forms then in effect under the Securities Act.

         (ii) If a  Company  Registration  Statement  involves  an  underwritten
offering and the managing underwriter advises the Company in writing that in its
opinion,  the number of  securities  requested  to be included  in such  Company
Registration  Statement  exceeds  the  number which can be sold in such offering
without  adversely  affecting  the  offering,  the Company shall include in such
Company  Registration  Statement the number of such securities which the Company
is  so  advised  can  be  sold  in such offering without adversely affecting the
offering, determined as follows:

                  (A) first,  the  securities proposed by the Company to be sold
for it own account, and

                  (B) second, any Restricted Securities requested to be included
in such  registration and any other securities of the Company in accordance with
the  priorities,  if and then existing among the holders of such  securities pro
rata among the holders thereof  requesting such registration on the basis of the
number of shares of such securities requested to be included by such holders.

         (iii)  The  Company  shall  not  be  obligated  to  include  Restricted
Securities in more than one (1) Company Registration Statement.

(c) To the extent Holder's Restricted  Securities are intended to be included in

                               REGISTRATION RIGHTS

         2.1      Securities Subject to this Agreement.

(a) The Securities entitled to the benefits of this Agreement are the Restricted
Securities, but only for so long as they remain Restricted Securities.

(b) A Person  is  deemed  to be a  holder  of  Restricted  Securities  (each,  a
"Holder")  whenever  such  Person is the  registered  holder of such  Restricted
Securities on the Company's books and records.

         2.2      Shelf Registration.

(a)      The Company shall:

         (i) as expeditiously as practicable, but no later than 30 calendar days
from the Closing Date, amend its Shelf Registration  Statement on Form S-1 filed
with the Commission on January 8, 1998 pursuant to Rule 415 under the Securities
Act,  which  Shelf  Registration  Statement  shall  provide  for  resale  of all
Restricted  Securities  the Holders of which shall have  provided to the Company
the information required pursuant to Section 2.2(c) herein; and

         (ii) use its best efforts to cause such Shelf Registration Statement to
be  declared  effective  by the  Commission  as soon as  possible  but within 60
calendar days after the Closing Date.

         (iii)  if the  Company  is  advised  by  the  SEC  that a  Registration
Statement  filed  hereunder is subject to a  "no-review"  and such  Registration
Statement is not declared effective within five (5) business days thereafter (an
"Acceleration  Date")  or,  irrespective  of  the  SEC  review,  a  Registration
Statement is not declared  effective by 60 calendar  days after the Closing Date
(the  "Target  Date"),  the Company  shall pay Holder as  liquidated  damages an
amount  equal to two percent  (2%) of the total  principal  sum of the Notes for
each thirty (30) day period  following the earlier of the  Acceleration  Date or
Target Date, as  applicable,  until such time as the  registration  statement is
declared  effective.  The payment set forth above shall be pro-rated daily as to
any period of less than  thirty  (30) days.  Such  payment  shall be made to the
Holder by cashier's  check or wire transfer in  immediately  available  funds to
such  account as shall be  designated  in writing by the Holder.  The  foregoing
amount shall be paid  irrespective  of the amount of Restricted  Securities then
held by Holder.

           (iv)  if,  following  effectiveness  of a  registration,  either  the
effectiveness of the registration statement is suspended or a current Prospectus
meeting the  requirements  of Section 10 of the  Securities Act is not available
for  delivery  by the  Holder  for any reason  (either  referred  to herein as a
"suspension"),  the Company shall thereupon pay to Holder as liquidated  damages
an amount  equal to two  percent  (2%) of the total  principal  sum of the Notes
previously  purchased  by  Holder  for  each  thirty  (30)  day  period  of  the
suspension.  The payment set forth above shall be pro-rated  daily as to periods
of less than  thirty  (30)  days.  Such  payment  shall be made to the Holder by
cashier's check or wire transfer in immediately  available funds to such account
as shall be designated in writing by the Holder,  and shall be paid irrespective
of the  amount  of  Restricted  Securities  held by  Holder on or after the date
following the suspension.

          (v) any amount  payable  pursuant to the foregoing  provisions of this
Subsection  (a) shall be  delivered  on or before the third (3rd)  business  day
following the end of the calendar month in which such payment obligation arose.

          (vi)   Subsections  (a)(iii)  and  (a)(iv)  are  in  addition  to  the
provisions of Section 4.7 hereof.

(b) In  connection  with the Shelf  Registration  Statement,  the Company  shall
comply with all the provisions of Section 2.4 below and shall
<PAGE>
use its best  efforts  to effect  such  registration  to permit  the sale of the
Restricted  Securities  being sold in  accordance  with the  intended  method or
methods of distribution  thereof (as indicated in the  information  furnished to
the  Company  pursuant to Section  2.2.  (c)).  The  Company  shall use its best
efforts  to keep  such  Shelf  Registration  Statement  continuously  effective,
supplemented  and amended to the extent necessary to ensure that it is available
for resales of Restricted  Securities  by the Holders of Restricted  Securities,
and to ensure that it conforms  with the  requirements  of this  Agreement,  the
Securities  Act and the policies,  rules and  regulations  of the  Commission as
announced  from time to time,  for a period of twenty  four (24) months from the
Closing Date or such shorter  period that will terminate when all the Securities
covered by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement or otherwise cease to be Restricted Securities.  Upon the
occurrence of any event that would cause any Shelf Registration Statement or the
Prospectus contained therein (i) to contain a material  misstatement or omission
or (ii)  not to be  effective  and  usable  for  sale or  resale  of  Restricted
Securities during the period required by this Agreement,  the Company shall file
promptly an appropriate  amendment to such Shelf  Registration  Statement or the
related  Prospectus or any document  incorporated  therein by reference,  in the
case of clause (i),  correcting any such  misstatement or omission,  and, in the
case of either clause (i) or (ii),  use its best efforts to cause such amendment
to be  declared  effective  and  such  Registration  Statement  and the  related
Prospectus to become usable for its intended  purpose(s) as soon as  practicable
thereafter.

(c) No  Holder  of  Restricted  Securities  may  include  any of its  Restricted
Securities in the Shelf Registration Statement pursuant to this Agreement unless
and until such Holder  furnishes  to the Company in writing,  within 10 Business
Days after receipt of a written request therefor,  such information specified in
Item 507 of Regulation S-K under the Securities Act or such other information as
the  Company  may  reasonably  request  for use in  connection  with  the  Shelf
Registration  Statement or Prospectus or preliminary Prospectus included therein
and in  any  application  to  the  NASD.  Each  Holder  as to  which  the  Shelf
Registration  Statement  is being  effected  agrees to furnish  promptly  to the
Company  all  information  required  to  be  disclosed  in  order  to  make  the
information  previously  furnished to the Company by such Holder not  materially
misleading.  No "Selling Shareholder Agreement" or other similar agreement shall
be required in order to secure registration of the Restricted Securities.

2.3      Piggyback Registration.

(a) At any  time  that  the  Company  proposes  to file a  Company  Registration
Statement,  either for its own  account or for the account of a  stockholder  or
stockholders, the Company shall give the Holders written notice of its intention
to do so and of the intended method of sale (the "Registration Notice") within a
reasonable time prior to the anticipated filing date of the Company Registration
Statement effecting such Company Registration. Each holder may request inclusion
of any Restricted  Securities in such Company  Registration by delivering to the
Company, within ten (10) Business Days after receipt of the Registration Notice,
a written  notice (the  "Piggyback  Notice")  stating  the number of  Restricted
Securities  proposed to be  included  and that such shares are to be included in
any  underwriting  only on the same terms and conditions as the shares of Common
Stock otherwise being sold through  underwriters under such Company Registration
Statement.  The  Company  shall use its best  efforts  to cause  all  Restricted
Securities  specified  in the  Piggyback  Notice to be  included  in the Company
Registration  Statement and any related offering, all to the extent requisite to
permit the sale by the Holders of such Restricted  Securities in accordance with
the method of sale  applicable  to the other shares of Common Stock  included in
such Company Registration Statement.

(b) The  Company's  obligation  to include  Restricted  Securities  in a Company
Registration  Statement  pursuant  to  Section  2.3(a)  shall be  subject to the
following limitations:

         (i) The Company may elect,  at its sole option and for any reason,  not
to register Holder's Restricted Securities; provided however, that this right is
limited to one (1) time and relative to one (1) particular Company  Registration
Statement.

         (ii) The  Company  shall not be  obligated  to include  any  Restricted
Securities in a registration statement filed on Form S-4, Form S-8 or such other
similar successor forms then in effect under the Securities Act.

         (iii) If a Company  Registration  Statement  involves  an  underwritten
offering and the managing underwriter advises the Company in writing that in its
opinion,  the number of  securities  requested  to be included  in such  Company
Registration  Statement  exceeds the number  which can be sold in such  offering
without  adversely  affecting  the  offering,  the Company  will include in such
Company  Registration  Statement the number of such Securities which the Company
is so advised  can be sold in such  offering  without  adversely  affecting  the
offering, determined as follows:
<PAGE>
                  (A) first, the securities proposed by the Company to be sold
for it own account, and

                  (B) second, any Restricted Securities requested to be included
in such  registration and any other securities of the Company in accordance with
the  priorities,  if and then existing among the holders of such  securities pro
rata among the holders thereof  requesting such registration on the basis of the
number of shares of such securities requested to be included by such holders.

         (iii)  The  Company  shall  not  be  obligated  to  include  Restricted
Securities in more than two (2) Company Registration Statement(s).

(c) No  Holder  of  Restricted  Securities  may  include  any of its  Restricted
Securities  in the Company  Registration  Statement  pursuant to this  Agreement
unless and until such Holder  furnishes  to the  Company in  writing,  within 10
business  days after receipt of a written  request  therefor,  such  information
specified in Item 507 of Regulation  S-K under the  Securities Act or such other
information as the Company may reasonably request for use in connection with the
Company Registration  Statement or Prospectus or preliminary Prospectus included
therein and in any  application to the NASD. Each Holder as to which the Company
Registration  Statement  is being  effected  agrees to furnish  promptly  to the
Company  all  information  required  to  be  disclosed  in  order  to  make  all
information  previously  furnished to the Company by such Holder not  materially
misleading.

Restricted  Securities  for  offering  or  sale  in  any  jurisdiction,  or  the
initiation of any proceeding for any of the preceding purposes, and
<PAGE>
         (iv) of the  existence  of any fact or the  happening of any event that
makes any statement of a material fact made in any such  Registration  Statement

incorporated  by reference  therein  untrue,  or that requires the making of any
additions  to or  changes  in any such  Registration  Statement  or the  related

If at any  time  the  Commission  shall  issue  any stop  order  suspending  the
effectiveness of such Registration Statement, or any state securities commission
or other regulatory  authority shall issue an order suspending the qualification
or  exemption  from  qualification  of the  Restricted  Securities  under  state
securities  or Blue Sky laws,  the Company shall use its  reasonable  efforts to
obtain the withdrawal or lifting of such order at the earliest possible time;

Registration Statement,  including, but not limited to, dispositions pursuant to
an underwritten registration, and in such connection:

         (i) make such representations and warranties to the selling Holders and
underwriter(s),  if any, in form, substance and scope as are customarily made by

pursuant to such Registration Statement are to be made to an underwriter(s));

         (iv)  provide for the  indemnification  provisions  and  procedures  of
Section 2.6 hereof with respect to selling  Holders and the  underwriter(s),  if

         (v)  deliver  such  documents  and  certificates  as may be  reasonably
requested by the selling  Holders or the  underwriter(s),  if any, and which are
customarily  delivered  in  underwritten  offerings  (whether  or  not  sales of

effectiveness of any Registration Statement.

The  actions  required  by clauses  (i)  through (v) above shall be done at each
closing  under  such  underwriting  or similar  agreement,  as and to the extent
required  thereunder,  and if at any time the  representations and warranties of

Statement and to file such consents to service of process or other  documents as
may be  necessary  in  order  to  effect  such  registration  or  qualification;
provided, however, that the Company shall not be required to register or qualify
as a foreign  corporation in any jurisdiction  where it is not then so qualified
or as a dealer in securities in any jurisdiction where it would not otherwise be
required to register or qualify but for this  Section 2.4, or to take any action
that would subject it to the service of process in suits or to taxation,  in any
jurisdiction where it is not then so subject;

(g) in  connection  with any sale of Restricted  Securities  that will result in
such  securities  no longer  being  Restricted  Securities,  cooperate  with the
selling  Holders  and the  underwriter(s),  if any,  to  facilitate  the  prompt
preparation and delivery of certificates  representing  Restricted Securities to
be sold and not  bearing any  restrictive  legends;  and enable such  Restricted
Securities  to be in such  denominations  and  registered  in such  names as the
Holders or the  underwriter(s),  if any,  may request at least two (2)  Business
Days prior to any sale of Restricted Securities made by such underwriters;

(h) use its best efforts to cause the  disposition of the Restricted  Securities

occurred,  prepare a supplement or post-effective  amendment to any Registration
Statement  or  related  Prospectus  or  any  document  incorporated  therein  by

fiscal quarter in which  Restricted  Securities are sold to the underwriter in a
firm or best efforts underwritten offering or (ii) if not sold to an underwriter

any notice from the Company of the  existence of any fact of the kind  described
in Section  2.4(c)(iv),  such Holder will forthwith  discontinue  disposition of
Restricted Securities pursuant to any Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus,  or until it is

         (ii) each other Person who participates as an underwriter in the
offering or sale of such securities,

         (iii) each person,  if any, who controls (within the meaning of Section
15 of the  Securities  Act or Section 20 of the Exchange Act) any such Holder or
underwriter  (any  of  the  persons  referred  to in  this  clause  (iii)  being
hereinafter referred to as a ("Controlling person") and

         (iv)  the  respective   officers,   directors,   partners,   employees,
representatives  and agents of any such Holder or underwriter or any controlling
person  (any  person  referred  to in  clause  (i),  (ii),  (iii)  or  (iv)  may
hereinafter be referred to as an "indemnified Person"),

to the fullest  extent  lawful  from and  against  any and all  losses,  claims,
damages,  liabilities,  judgments or  expenses,  joint or several (or actions or
proceedings, whether commenced or threatened, in respect thereof) (collectively,
"Claims"),  to which such  indemnified  Person may become  subject  under either
Section 15 of the Securities Act or Section 20 of the Exchange Act or otherwise,
insofar  as such  Claims  wise out of or are based  upon,  or are  caused by any
untrue
<PAGE>
statement  or alleged  untrue  statement  of a material  fact  contained  in any
Registration  Statement or Prospectus (or any amendment or supplement  thereto),
or any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, or
a violation by the Company of the Securities Act or any state securities law, or
any  rule or  regulation  promulgated  under  the  Securities  Act or any  state
securities law, or any other law applicable to the Company  relating to any such
registration or qualification,  except insofar as such losses, claims,  damages,
liabilities,  judgments  or expenses  of any such  indemnified  Person;  (x) are
caused by any such untrue  statement or omission or alleged untrue  statement or
omission  that is based upon  information  relating to such  indemnified  Person
furnished  in writing to the Company by or on behalf of any of such  indemnified
Person  expressly  for  use  therein;   (y)  with  respect  to  the  preliminary
Prospectus, result from the fact that such Holder sold Securities to a person to
whom there was not sent or given,  at or prior to the  written  confirmation  of
such sale, a copy of the Prospectus, as amended or supplemented,  if the Company
shall have previously  furnished copies hereof to such Holder in accordance with
this  Agreement  and said  Prospectus,  as amended or  supplemented,  would have
corrected such untrue statement or omission; or (z) as a result of the use by an
indemnified  Person of any  Prospectus  when,  upon receipt of a notice from the
Company  of the  existence  of  any  fact  of  the  kind  described  in  Section
2.4(b)(iv), the indemnified Person or the related Holder was not permitted to do
so.  Such  indemnity  shall  remain in full force and effect  regardless  of any
investigation  made by or on behalf of any indemnified  Person and shall survive
the transfer of such securities by such Holder.

In case any action shall be brought or asserted  against any of the  indemnified
Persons with respect to which indemnity may be sought against the Company,  such
indemnified  Person  shall  promptly  notify the Company  and the Company  shall
assume the  defense  thereof  Such  indemnified  Person  shall have the night to
employ  separate  counsel in any such action and to  participate  in the defense
thereof,  but the fees and expenses of such  counsel  shall be at the expense of
the indemnified Person unless (i) the employment of such counsel shall have been
specifically  authorized in writing by the Company,  (ii) the Company shall have
failed to assume the  defense and employ  counsel or (iii) the named  parties to
any such action  (including any implied  parties)  include both the  indemnified
Person and the Company and the  indemnified  Person  shall-have  been advised in
writing by its counsel that there may be one or more legal defenses available to
it which are different from or additional to those  available to the Company (in
which case the  Company  shall not have the right to assume the  defense of such
action on behalf of the indemnified Person), it being understood,  however, that
the  Company  shall not,  in  connection  with such action or similar or related
actions  or  proceedings   arising  out  of  the  same  general  allegations  or
circumstances,  be liable for the reasonable  fees and expenses of more than one
separate  firm of attorneys  (in addition to any local  counsel) at any time for
all  the  indemnified  Persons,  which  firm  shall  be (x)  designated  by such
indemnified Persons and (y) reasonably  satisfactory to the Company. The Company
shall not be liable for any settlement of any such action or proceeding effected
without the Company's prior written consent, which consent shall not be withheld
unreasonably,  and the  Company  agrees  to  indemnify  and  hold  harmless  any
indemnified Person from and against any loss, claim, damage, liability, judgment
or expense by reason of any  settlement of any action  effected with the written
consent of the Company. The Company shall not, without the prior written consent
of each  indemnified  Person,  settle or  compromise  or consent to the entry of
judgment on or otherwise  seek to  terminate  any pending or  threatened  action
claim,   litigation  or  proceeding  in  respect  of  which  indemnification  or
contribution may be sought hereunder (whether or not any indemnified Person is a
party  thereto),  unless such  settlement,  compromise,  consent or  termination
includes an unconditional  release of each indemnified Person from all liability
arising out of such action, claim litigation or proceeding.

(b) Each Holder of Restricted  Securities covered by any Registration  Statement
agrees,  severally  and not jointly,  to indemnify and hold harmless the Company
and its directors,  officers and any person  controlling  (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company,
and the respective officers, directors, partners, employees, representatives and
agents of each person,  to the same extent as the foregoing  indemnity  from the
Company to each of the indemnified Persons, but only (i) with respect to actions
based on  information  relating  to such  Holder  furnished  in writing by or on
behalf  of such  Holder  expressly  for  use in any  Registration  Statement  or
Prospectus,  and (ii) to the extent of the gross proceeds,  if any,  received by
such  Purchaser  from  the sale or other  disposition  of his or its  Restricted
Securities  covered  by such  Registration  Statement.  In case  any  action  or
proceeding  shall be brought against the Company or its directors or officers or
any such controlling  person in respect of which indemnity may be sought against
a Holder of Restricted  Securities covered by any Registration  Statement,  such
Holder  shall have the rights and  duties  given the  Company in Section  2.8(a)
(except  that the Holder  may but shall not be  required  to assume the  defense
thereof),  and the Company or its  directors  or  officers  or such  controlling
person shall have the rights and duties given to each Holder by Section 2.8(a).
<PAGE>
(c) If the indemnification provided for in this Section 2.8 is unavailable to an
indemnified  party  under  Section  2.7(a)  or (b)  (other  than  by  reason  of
exceptions  provided  in those  Sections)  in  respect  of any  losses,  claims,
damages,  liabilities,  judgments  or expenses  referred  to therein,  then each
applicable  indemnifying  party (in the case of the  Holders  severally  and not
jointly),  in lieu of indemnifying such indemnified  party,  shall contribute to
the amount paid or payable by such indemnified party as a result of such losses,
claims damages, liabilities,  judgments of expenses (i) in such proportion as is
appropriate to reflect the relative  benefits received by the Company on the one
hand and the Holder on the other hand from sale of Restricted Securities or (ii)
if such  allocation  provided by clause (i) above is not permitted by applicable
law, in such  proportion  as is  appropriate  to reflect  not only the  relative
benefits  referred  to in clause  (i) above but also the  relative  fault of the
Company and such Holder in connection  with the  statements  or omissions  which
resulted in such losses, claims, damages, liabilities, judgments or expenses, as
well as any other relevant equitable  considerations.  The relative fault of the
Company on the one hand and of such Holder on the other shall be  determined  by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged  omission to state a material fact
relates to information supplied by the Company or by such Holder and the parties
relative intent, knowledge,  access to information and opportunity to correct or
prevent such  statement  or omission.  The amount paid to a party as a result of
the losses,  claims,  damages,  liabilities  judgments and expenses  referred to
above shall be deemed to include,  subject to the  limitations  set forth in the
second  paragraph  of  Section  2.8(a),  any  legal  or other  fees or  expenses
reasonably  incurred by such party in connection with investigating or defending
any action or claim.

The Company and each Holder of Restricted Securities covered by any Registration
Statement agree that it would not be just and equitable if contribution pursuant
to this  Section  2.8(c) were  determined  by pro rata  allocation  (even if the
Holders were  treated as one entity for such  purpose) or by any other method of
allocation  which  does not  take  into  account  the  equitable  considerations
referred  to  in  the  immediately  preceding  paragraph.   Notwithstanding  the
provisions of this Section 2.8(c) no Holder (and none of its related indemnified
Persons) shall be required to contribute, in the aggregate, any amount in excess
of the amount by which the dollar  amount of  proceeds  received  by such Holder
upon the sale of the  Restricted  Securities  exceeds  the amount of any damages
which such Holder has  otherwise  been  required to pay by reason of such untrue
statement  or  omission  or alleged  omission.  No person  guilty of  fraudulent
misrepresentations  (within the meaning of Section 11(f) of the Securities  Act)
shall be  entitled  to  contribution  from any person who was not guilty of such
fraudulent misrepresentation.

The indemnity and contribution  provisions  contained in this Section 2.8 are in
addition to any liability  which the  indemnifying  person may otherwise have to
the indemnified persons referred to above.

2.9      Participation in Underwritten Registrations.

No Holder may participate in any underwritten registration hereunder unless such
Holder  (a)  agrees to sell such  Holder's  Restricted  Securities  on the basis
provided in any  underwriting  arrangements  approved  by the  Persons  entitled
hereunder  to approve  such  arrangements  and (b)  completes  and  executes all
reasonable  questionnaires,   powers  of  attorney,  indemnities,   underwriting
agreements, lock-up letters and other documents required under the terms of such
underwriting arrangements.

2.10     Selection of Underwriters.

The Holders of Restricted  Securities covered by any Registration  Statement who
desire to do so may sell such Restricted Securities in an underwritten offering.
In any such underwritten  offering,  the investment banker or investment bankers
and manager or managers  that will  administer  the offering will be selected by
the Holders of a majority of the Restricted Securities included in such offering
if such registration is pursuant to the Shelf Registration Statement, and by the
Company if such  registration is pursuant to a Company  Registration  Statement;
provided,  however, that such investment bankers and managers must be reasonably
satisfactory  to the  Company  or the  Holders,  respectively.  Such  investment
bankers and managers are referred to herein as the "underwriters".

Stock from such  Holders of  Restricted  Securities  or  beneficial  owner,  the
information required by Rule 144A(d)(4) under the Act in order to permit resales
of such Restricted Securities pursuant to Rule 144A.

EXHIBIT 4.10

THIS SECURITIES PURCHASE AGREEMENT,  as it may be amended from time to time (the
"Agreement"),  dated as of the ___ day of ______,  1998,  is entered into by and
among ENVIRONMENTAL REMEDIATION HOLDING CORPORATION, a Colorado corporation (the
"Company");  and the persons and/or entities who have executed this Agreement on
the  signature  pages  hereof  (hereinafter   referred  to  individually  as  an
"Investor" and collectively as the "Investors").

                                   WITNESSETH:

WHEREAS, the Company desires to sell to the Investors,  and the Investors desire
to purchase from the Company, certain convertible notes of the Company entitling
the Investors to purchase  certain  shares of capital stock of the Company,  for
the respective purchase prices and upon the terms and conditions hereinafter set
forth;

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein
contained, the parties hereby agree as follows:

1. AUTHORIZATION OF ISSUE.

The Company has  authorized the issuance and sale to the Investors of: (i) up to
$3,000,0000  principal  amount  of the  Company's  8.0%  convertible  notes  due
______________, 2000 (the "Notes").

(a)      The Notes shall be substantially in the form of Exhibit A annexed
hereto and made a part hereof.

2. ISSUANCE OF NOTES; REGISTRATION OF CONVERSION SHARES AND OPTION SHARES.

(a) Issuance of Notes.  On the terms and subject to the  conditions  hereinafter
set forth, on the Closing Date (as hereinafter defined),  the Company will issue
and sell to each Investor the principal  amount of Notes set forth  opposite the
name of each such Investor on Schedule I hereto and made a part hereof.

(b) Purchase  Price:  Payment.  The  purchase  price for each of the Notes shall
equal 100% of the aggregate principal amount thereof. The purchase price payable
by each  Investor  shall be the amount set forth  opposite the name of each such
Investor on Schedule 1 annexed hereto. The purchase price for the Notes shall be
paid at the  Closing  by wire  transfer  of  immediately  available  funds or by
certified or bank cashier's  checks (at the option of the Investors)  payable to
the order of the  Company,  or  otherwise  as  acceptable  to the  Company.  The
purchase price shall be payable by each Investor  against  delivery of the Notes
being  purchased  by it,  all of which  shall be  registered  in the name of the
respective Investor purchasing such Notes.

(c)  Registration of Conversion  Shares.  The Company shall file with the United
States  Securities and Exchange  Commission  ("SEC") and use its best efforts to
cause to be  declared  effective  a Form  S-1  Registration  Statement  or other
appropriate   form  of   registration  in  order  to  register  for  resale  and
distribution  under the  Securities  Act of 1933,  as amended  (the  "Securities
Act"),  all shares of Common  Stock of the Company  issuable  upon  voluntary or
mandatory conversion of all Notes (the "Conversion Shares").  The obligations of
the  Company  to so  register  the  Conversion  Shares  are  set  forth  in  the
registration  rights  agreement,  dated of even date herewith and in the form of
Exhibit  B annexed  hereto  and made a part  hereof  (the  "Registration  Rights
Agreement").

3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

As used in this Agreement, the term "Subsidiary" or "Subsidiaries"
shall mean: (i) the individual or collective reference to the
corporations listed on Schedule 2 annexed hereto and made a part
hereof, including, without limitation, Bass American Petroleum Corp.
("BAPCO"). The Company hereby represents and warrants to the
Investors, as follows:
<PAGE>
(a)  Organization  and Good  Standing.  The  Company  and  each of its  existing
Subsidiaries  is a  corporation  duly  organized,  validly  existing and in good
standing under the laws of its state of incorporation, with full corporate power
and  authority  to own its  properties  and carry on its  business  as now being
conducted.  Each of the Company and such  Subsidiaries is qualified as a foreign
corporation and is in good standing in each jurisdiction in which the conduct of
its business or the ownership of its assets requires such qualification.

(b)  Capitalization  of the  Company.  The  authorized,  issued and  outstanding
capital  stock  of  the  Company  is  described  on  the   Company's   Form  S-1
supplementally  submitted to the Securities and Exchange  Commission (the "SEC")
on January 8, 1998 (the "Form S-1"), as amended.  The Company's Form S-1 and all
other  documents and reports filed by the Company and/or its  Subsidiaries  with
the SEC since October 1, 1995 (the "SEC  Documents")  have been  furnished to or
otherwise  made  available  to  the  Investors  or  their  representatives.  The
authorized,  issued  and  outstanding  shares  of  capital  stock of each of the
Subsidiaries are disclosed on the SEC Documents.

(c)  Authorization,  Execution  and Effect of  Agreements.  The  Company has all
requisite  corporate  power and  authority  to execute,  deliver and perform its
obligations under this Agreement and the Registration  Rights Agreement to issue
the Notes in the manner and for the purpose contemplated by this Agreement,  and
to execute,  deliver and perform its obligations under this Agreement, the Notes
and  the   Registration   Rights  Agreement   (collectively,   the  "Transaction
Documents")  and all other  agreements and  instruments  heretofore or hereafter
executed and delivered by it pursuant to or in connection  with this  Agreement.
The execution and delivery of the Transaction  Documents and the consummation of
the transactions  contemplated hereby have been duly authorized by all necessary
corporate  action of the  Company.  This  Agreement  and the  other  Transaction
Documents have each been duly executed and delivered and  constitutes,  and upon
execution and delivery in accordance herewith each other agreement or instrument
executed and delivered by the Company pursuant hereto, including the Notes, will
constitute, the legal, valid and binding obligations of the Company, enforceable
against the Company in accordance with their respective  terms,  subject in each
such case, to applicable bankruptcy, insolvency, reorganization and similar laws
affecting   creditors'  rights  and  remedies  generally  and  subject,   as  to
enforceability,   to  general   principles  of  equity  (regardless  of  whether
enforcement is sought in a proceeding at law or in equity).

(d)  Conflicting  Agreements  and Other  Matters.  The  execution,  delivery and
performance  by  the  Company  of  this  Agreement  and  the  other  Transaction
Documents,  and all other agreements and instruments  heretofore or hereafter to
be executed and delivered by the Company in connection with the  consummation of
the  transactions  contemplated  by this  Agreement  and the  other  Transaction
Documents,  and compliance by the Company with the terms and  provisions  hereof
and thereof applicable to it, including the issuance and sale of the Notes, does
not and will not (i) violate any provision of any law, rule, regulation,  order,
writ,   judgment,   decree,   administrative   determination   or  award  having
applicability to the Company or any of the Subsidiaries or (ii) conflict with or
result  in a  breach  of or  constitute  a  default  under  the  Certificate  of
Incorporation  or By-Laws  of the  Company  or any of the  Subsidiaries,  or any
indenture  or loan or credit  agreement,  or any  other  material  agreement  or
instrument,  to which the  Company or any of the  Subsidiaries  is a party or by
which the Company or the Subsidiaries, or any of their respective properties are
bound or affected, and will not result in, or require the creation or imposition
of,  any lien upon or with  respect  to any of the  properties  now owned by the
Company or any of the  Subsidiaries or hereafter  acquired by the Company or any
of the Subsidiaries.

(e) Financial Information.  The (i) audited consolidated financial statements of
the  Company for the fiscal  year ended  September  30, 1997 as set forth in the
Company's  Form 10-K/A  filed with the SEC, as amended  from time to time,  (the
"1998 Form 10-K");  (ii) the unaudited  financial  statements of the Company for
the nine  months  ended  December  31, 1997 as set forth in the  Company's  Form
10-Q/A  filed with the SEC, as amended from time to time (the "1998 Form 10Q/A")
and (iii) the unaudited financial statements of he Company for the quarter ended
March 31, 1998 as set forth in the Company's  form 10-Q/A filed with the SEC, as
amended ("Second Quarter 1998 10-Q"), were prepared in accordance with generally
accepted accounting principles ("GAAP") consistently applied, and fairly present
the  financial  condition  and  results of  operations  of the  Company  and the
Subsidiaries for the periods  indicated  therein;  provided,  that the unaudited
financial  statements do not contain certain footnote disclosures required under
GAAP  for  audited  financial  statements  and are  subject  to year  end  audit
adjustments,  none of which  would be  material  to an  Investor's  decision  to
purchase the Notes.

Included  in the  Form S-1 and the  Amended  Form S-1  filed  with the SEC,  the
Company  disclosed  the  acquisition  of certain  assets from Mytec & Associates
(Mytec),  including  certain  oil and gas  reserves.  The SEC has  reviewed  the
financial  statements on this  acquisition  and has reviewed the reserve  report
dated  February  1997, as revised  March 1998, by Dr. Joseph Shoaf,  a petroleum
engineer, who estimated the reserves for these properties at $14,335,646.
<PAGE>
While there is no issue with the SEC as to the value of the reserves,  Mytec did
not have three (3) years of audited  financial  statements for these properties.
Under the  accounting  principles  promulgated  in Regulation  S-X, such audited
financials  are a requirement  in order to take  advantage of the normal oil and
gas  accounting  provisions  which  allow for  reserve  valuation.  Without  the
advantages of the GAAP accounting  provisions on these reserves,  such asset may
be booked only at valuation  of the  consideration  given.  The Company paid for
this  acquisition  in  stock  which  had a  market  value  at  the  time  of the
transaction of $515,000.  Based on this lack of financial statements the Company
only had four (4)  options  on how the  Company  may handle  this  matter in its
Second Amended Form S-1. The alternatives and the Company's position on each are
as follows:

                  (i)Return the assets to Mytec - the Company does not feel that
this would be in the best interest of the Company since it has already  expended
approximately  $500,000 in well rework  procedures and well equipment repair and
the  Company  would  forego  any  recapture  of that  money if it  returned  the
properties.

                  (ii)Withdraw  the Form S-1 and  resubmit it after the December
1998  Company  financials  become  available-  the  Company  believes  that  its
obligations  relative  to the funding  provided  on November  15, 1997 by Avalon
Research  Group,  Inc.   ("Avalon")  and  the  Private  Equity  Line  of  Credit
established with Kingsbridge Capital Limited ("Kingsbridge")
in March 1998 preclude such alternative.

                  (iii)Wait to submit the Second Amendment to the Form S-1 until
three (3) years of audited  financial  statements  can be prepared for the Mytec
properties - the Company  believes  that such work could not be completed  until
February  1999 at the  earliest,  and for the same  reason  as set forth in 3(B)
above, that this alternative is precluded.

                  (iv)Restate  the book  value of the asset at the amount of the
consideration  given to acquire  the  properties  - the  Company  has elected to
accept this last  alternative  since it believes that the SEC  requirement is an
accounting  requirement  which does not impact upon the underlying  value of the
reserves.  Accordingly,  while the asset was booked  previously at approximately
$14  million,  it  will  now be  carried  at  $515,000.  That  will  reduce  the
shareholders'  equity to $1.1  million for  September  1997 and $1.6 million for
March,  1998.  Additionally,  as the Company  recovers the  reserves  from these
properties,  it will be  recording  depletion  expense  significantly  below the
industry  normal  because of this lower basis in the  properties.  The effect of
this will be that the Company  will record  greater  profits per barrel than the
industry norm.

The Company's  Second  Amendment  intends to incorporate the change in Paragraph
3(e)(iv).

(f) Litigation, Proceedings: Defaults. Except as disclosed on the SEC Reports or
on Schedule 3(f) hereto, there is no action,  suit,  proceeding or investigation
pending or, to the knowledge of the Company, threatened against or affecting the
Company or any of the Subsidiaries or any of their respective  properties before
or by any court,  governmental or regulatory authority (federal, state, local or
foreign)  which either (i) relates to or challenges  the  legality,  validity or
enforceability  of this  Agreement  or any other  document  or  agreement  to be
executed and delivered by the Company pursuant hereto or in connection herewith,
or (ii) if determined  adversely (A) would have a material adverse effect on the
condition (financial or otherwise),  properties,  assets, business or results of
operations  of the  Company or the  Subsidiaries,  when taken as a  consolidated
whole (a  "Material  Adverse  Effect")  after giving  effect to the  transaction
contemplated by this Agreement,  or (B) could  materially  impair the ability or
obligation of the Company or the Subsidiaries to perform fully on a timely basis
any  obligation  which it has or will have  under  this  Agreement  or the other
Transaction  Documents,  or  any  other  agreement  or  document  heretofore  or
hereafter  to be  executed  by the  Company  pursuant  hereto  or in  connection
herewith. Neither the Company nor any of the Subsidiaries is in violation of its
Certificate  of  Incorporation  or  By-Laws.  Neither the Company nor any of the
Subsidiaries  is (i) in  default  under or in  violation  of any other  material
agreement  or  instrument  to  which  it is a party or by which it or any of its
properties  are bound or  affected,  which  default  or  violation  would have a
Material Adverse Effect, (ii) in default with respect to any order of any court,
arbitrator or governmental body or subject to or party to any order of any court
or governmental  authority  arising out of any action,  suit or proceeding under
any statute or other law  respecting  antitrust,  monopoly,  restraint of trade,
unfair  competition  or similar  matters,  or (iii) in violation of any statute,
rule or regulation of any governmental authority material to its business.
<PAGE>
(g) Governmental Consents, etc. No authorization,  consent,  approval,  license,
qualification  or  formal  exemption  from,  nor  any  filing,   declaration  or
registration with, any court, governmental agency or regulatory authority or any
securities exchange or any other person or entity (collectively  "Approvals") is
required  in  connection  with the  execution,  delivery or  performance  by the
Company of this Agreement.

(h) Use of  Proceeds.  The  proceeds to the  Company  from the sale of the Notes
shall be used for  general  working  capital  purposes,  and to perform  certain
obligations  under its June 1997 joint  venture  agreement  with the  Democratic
Republic of Sao Tome & Principe for the  development  of  potential  oil and gas
reserves in the Gulf of Guinea of West Africa (the "Sao Tome Project"), with the
balance,  if any used by the Company for additional payments for general working
capital  purposes or to perform on its  obligations to the Sao Tome Project,  as
the Company so directs.

(i)  Accuracy  of all SEC  Public  Filings,  All SEC  Reports  furnished  to the
Investors or their  representatives and all other documents and reports filed by
or on behalf of the Company with the SEC, when filed, did not contain any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein or necessary in order to make the statements therein, in light of
the  circumstances  under which they were made, not misleading.  The Company and
each of its  Subsidiaries  has filed,  on a timely  basis,  all required  forms,
reports and  documents  with the SEC  required to be filed by it pursuant to the
Securities  Act and the  Securities  and Exchange  Act of 1934,  as amended (the
"Exchange  Act"),  all of which  complied at the time of filing in all  material
respects with all applicable requirements of the Securities Act and the Exchange
Act.

Although  the Company  believed  that  disclosures  made in the Form S-1 and the
Amended Form S-1 and all SEC Reports  previously filed were accurate and true at
the time made,  based upon the planned  revisions set forth herein to the Second
Amended Form S-1, which have required refiling of the Company's, 10-Q's and 10-K
filed since June 30, 1997, the Company  believes that as currently  filed,  such
SEC Reports are  incorrect  and require  amendment  to the extent of the planned
revisions disclosed herein.

(j)  Absence of  Certain  Changes or  Events.  Since  June 30,  1997,  except as
contemplated  by this  Agreement,  disclosed on Schedule  3(j) hereto and made a
part  hereof,  or disclosed in any Company SEC Report filed since June 30, 1997,

comparable authority;
<PAGE>
         (iii) there is no demand for recognition made by any labor organization
or petition for election  filed with the National Labor  Relations  Board or any
other comparable authority which, individually or in the aggregate, would have a
Material Adverse Effect;

         (iv) no grievance or any arbitration proceeding arising out of or under
collective  bargaining  agreements  is pending and, to the best of the Company's
knowledge,  no claims  therefor have been  threatened  other than  grievances or

         (v)  there  is  no  litigation,  arbitration  proceeding,  governmental
investigation, administrative charge, citation or action of any kind pending or,
to the  knowledge  of the  Company  or any  of  its  Subsidiaries,  proposed  or

the  Subsidiaries  own,  and  as of  the  Closing  Date,  the  Company  and  the
Subsidiaries  will  own,  good  and  marketable  title  to all of  their  assets
constituting  personal property which is material to their business  (excluding,
for purposes of this sentence,  assets held under leases), free and clear of any
and all mortgages, liens, encumbrances,  charges, claims, restrictions, pledges,
security interests or impositions (collectively, "Liens") except as set forth in
the Company SEC Reports or Schedule 3(m) annexed  hereto and made a part hereof.
Such assets,  together with all assets held by the Company and the  Subsidiaries
under leases,  include all tangible and intangible personal property,  contracts
and rights  necessary or required for the  operation  of the  businesses  of the
Company.  As of the date hereof, the Company and the Subsidiaries own, and as of
the Closing Date, the Company and the Subsidiaries will own, good and marketable
title to all of their real  estate,  including  oil and gas  reserves,  which is

except as set forth in the  Company  SEC  Reports or in  Schedule  3(m)  annexed

have a Material Adverse Effect.  Such assets,  together with real estate and oil
and gas reserve  assets held by the Company and the  Subsidiaries  under leases,
are adequate for the operation of the  businesses  of the Company,  as presently
conducted.  The  leases to all real  estate and oil and gas  reserves  which are
material to the operations of the businesses of the Company and the Subsidiaries
are in full force and effect and no event has occurred  which,  with the passage
of time, the giving of notice,  or both,  would constitute a default or event of
default by the Company or any  Subsidiary  or, to the  knowledge of the Company,
any other person who is a party signatory  thereto,  other than such defaults or
events of default  which,  individually  or in the  aggregate,  would not have a
Material Adverse Effect.

4.       REPRESENTATIONS AND WARRANTIES OF THE INVESTORS.

Each  Investor  hereby  separately  represents  and  warrants  to the Company as
follows (such  representations  and warranties being made separately and only to
the extent such representations and warranties relate to such Investor):
<PAGE>
(a) Investigation;  Investment Representation.  Each Investor (i) possesses such
knowledge and experience in financial and business matters that it is capable of
evaluating  the  merits  and risks of its  investment  hereunder;  (ii) has been
afforded the  opportunity  to ask  questions of, and receive  answers from,  the
Company concerning the terms and conditions of its investment,  the transactions
contemplated  hereby and the  business  and  affairs of the  Company;  (iii) has
examined,  to the  extent  it  deems  appropriate,  all of  the  agreements  and
documents referred to herein or in the schedules hereto and such other documents
that it has  requested;  and (iv)  understands  that  the  Notes  are not  being
registered under the Securities Act of 1933, as amended,  on the ground that the
issuance  thereof  is  exempt  from  registration  under  Section  4(2)  of  the
Securities Act of 1933, as amended,  as a transaction by an issuer not involving
a public offering, and the Company's reliance on this exemption is predicated in
part on the Investors'  representations and warranties contained in this Section
4(a).  The  Investors  are  acquiring  the  Notes for  their  own  account,  for
investment  purposes  only  and  not  with a view to the  sale  or  distribution
thereof.

(b) Execution and Effect of Agreement. Each Investor has all necessary power and
authority  to  enter  into  this  Agreement  and  consummate  the   transactions
contemplated  hereby.  This Agreement  constitutes the legal,  valid and binding
obligation  of each  Investor,  enforceable  against each Investor in accordance
with its terms, subject to applicable  bankruptcy,  insolvency,  reorganization,
moratorium and similar laws affecting  creditors' rights and remedies  generally
and subject,  as to enforceability,  to general principles of equity (regardless
of whether enforcement is sought in a proceeding at law or in equity).

5.       COVENANTS.

As long as any of the Notes are outstanding,  the Company agrees that, unless it
first procures the written  consent to act otherwise of the holders of record of
66-2/3%  of the  outstanding  principal  amount  of the  Notes  of  record  then
outstanding, it will use its best efforts to cause each of its Subsidiaries to:

(a) Promptly pay all taxes (exclusive of income taxes imposed on the Investors),
fees and charges payable, or ruled to be payable, by any federal, state or local
authority,  in respect of this Agreement or the execution,  delivery or issuance
of the Notes by reason of any now existing or hereafter  enacted federal,  state
or local  statute or ordinance,  and  indemnify and hold the Investors  harmless
from and against all liabilities  with respect to or in connection with any such
taxes, fees or charges.

(b) Maintain  their  corporate  existence  and right to carry on business,  duly
procure  all  necessary  renewals  and  extensions  thereof,  and use their best
efforts to  maintain,  preserve and renew all  necessary  or  desirable  rights,
powers, privileges and franchises owned by them.

(c)  Promptly  notify  the  Investors  of any  material  adverse  change  in the
condition (financial or otherwise),  properties,  assets, business or results of
operations of the Company or any of the Subsidiaries.

(d)      Not cause, suffer or permit any liquidation, winding up or
dissolution of the Company or the Subsidiaries.

(e)      Maintain and cause the Subsidiaries to maintain a system of
accounting established and administered in accordance with generally
accepted accounting principles.

(f)      Comply with all of the covenants and agreements on the part of
the Company to be performed under the terms of the Notes and the other
Transaction Documents.

6.       FINANCIAL STATEMENTS; INSPECTION; NON-PUBLIC INFORMATION.

(a) The Company will furnish to each Investor (and their permitted  transferees,
successors  and  assigns),  as long as such  Investor  owns any of the  Notes or
copies of all Form 10-K Annual Report and Form 10- Q Quarterly Financial Reports
filed by the Company, with the SEC.

(b) The Company will,  subject to execution of appropriate  confidentiality  and
non-  disclosure  agreements,  permit the Investors,  as long as they own Notes,
shares of Common Stock  issuable upon  conversion of the Notes (the  "Conversion
Shares") or any authorized  representative designated by the Investors, to visit
and inspect at the  Investors'  expense any of the properties of the Company and
the  Subsidiaries,  and to discuss  its  affairs,  finances  and  accounts  with
officers  of the  Company,  all at such  reasonable  times  and as  often as the
Investors may reasonably request.

(c) The  Company  in no  event  shall  disclose  non-public  information  to the
Investors,  advisors to or  representatives  of the  Investors  unless  prior to
disclosure of such information the Company marks such information as 'Non-Public
Information  -  Confidential"  and provides  the  Investors,  such  advisors and
representatives with a reasonable opportunity to accept or refuse to accept such
non-public  information for review.  Nothing herein shall require the Company to
<PAGE>
disclose non-public information to the Investors or their respective advisors or
representatives,  and  the  Company  represents  that it  does  not  disseminate
non-public  information  to any Investors who purchase stock in the Company in a
public offering, to money managers or to securities analysts; provided, however,
that  notwithstanding  anything  herein to the  contrary,  the Company  will, as
hereinabove provided, notify immediately the advisors and representatives of the
Investors  and,  if any,  underwriters,  of any  event or the  existence  of any
circumstance   (without  any  obligation  to  disclose  the  specific  event  or
circumstance)  of which it becomes aware,  constituting  non-public  information
(whether or not requested of the Company  specifically  or generally  during the
course of due diligence by such persons or entities), which, if not disclosed in
the  Prospectus  included  in  the  Registration  Statement,  would  cause  such
Prospectus  to  include  a  material  misstatement  or to omit a  material  fact
required to be stated therein in order to make the statements, therein, in light
of the  circumstances  in which they were made, not  misleading.  Nothing herein
shall be  construed  to mean  that  such  persons  or  entities  other  than the
Investors  (without the written  consent of the Investors prior to disclosure of
such  information)  may not  obtain  non-public  information  in the  course  of
conducting  due  diligence in  accordance  with the terms of this  Agreement and
nothing  herein shall  prevent any such persons or entities  from  notifying the
Company of their  opinion  that based on such due  diligence  by such persons or
entities,  that the  Registration  Statement  contains an untrue  statement of a
material fact or omits a material fact required to be stated in the Registration
Statement or necessary to make the statements contained therein, in light of the
circumstances in which they were made, not misleading.

7.       TRANSFER OF NOTES

(a)  Permissible  Transfers.   The  Investors  acknowledge  that  the  Company's
securities  being issued and sold to them hereunder are being so issued and sold
in  transactions  which are exempt  from the  registration  requirements  of the
Securities  Act of 1933,  as  amended.  None of the Notes or  Conversion  Shares
issuable  upon  conversion of the Notes,  may be  distributed,  transferred,  or
otherwise  disposed  of  by  the  Investors  except  pursuant  to  an  effective
Registration  Statement  under  such Act which is  current  with  respect to the
securities offered thereby,  or pursuant to an applicable  exemption  therefrom,
and pursuant to applicable  "Blue Sky" or state securities laws or an applicable
exemption therefrom.

(b) Legend.  Unless the Conversion  Shares have been  registered  pursuant to an
effective  Registration Statement filed under the Securities Act or held for the
requisite  period to be freely  transferable  pursuant  to Rule 144  promulgated
under the Securities  Act and otherwise  comply with Rule 144(k) (in either such
case the certificates  shall bear no legend),  the Company shall cause to be set
forth  on  the  certificates   representing  any  Conversion   Shares  a  legend
substantially in the following form: "The shares represented by this certificate
have not been  registered  under the  Securities  Act of 1933,  as  amended.  No
transfer of such shares shall be valid or effective except in accordance with an
effective  registration  statement covering such shares or an opinion of counsel
acceptable  to the Company  that  registration  of such  shares is not  required
pursuant  to the  applicable  requirements  of the  Securities  Act of 1933,  as
amended."

(c) Registration of Conversion  Shares,  Other Exemption.  The Company shall use
its best efforts to cause the  Conversion  Shares to be registered for resale or
distribution  under the Securities  Act, all in accordance with the terms of the
Registration Rights Agreement in the form annexed hereto as Exhibit B and made a
part hereof.

8.       CONDITIONS PRECEDENT TO CLOSING.

9.       CLOSING.

The  closing  hereunder  (the  "Closing")  shall take place at 10:00 A.M. at the
offices of  Greenberg  Traurig  Hoffman  Lipoff  Rosen & Quentel,  153 East 53rd
Street, New York, New York 10022 on or before __________, 1998, or at such other
location as may be mutually agreed upon. The date of such Closing is referred to
in this Agreement as the "Closing Date".

(a) At the  Closing,  in  addition  to  true  copies  of the  other  Transaction
Documents  duly  executed  by the  Company,  the Company  shall  deliver to each
Investor  in the  respective  amounts  set  forth  on  Schedule  1 hereto a duly

purchase price therefor by wire transfer of  immediately  available  funds or by
certified or bank cashier's check payable to the order of the Company.

(b) At the Closing, each Investor shall wire transfer the purchase price for the
Notes subscribed to by such Investor to the Bank of New York, as provided in the
Escrow Agreement attached as Exhibit D.

10.      ADJUSTMENT TO TERMS OF NOTES.

In the event and to the extent  that the Company  shall,  at any time within one
hundred and twenty (120) days  following the Closing Date,  issue any (a) notes,
debentures,  bonds  or  other  debt  instruments  which,  by  their  terms,  are
convertible into shares of Common Stock of the Company,  (b) shares of preferred
stock, which, by their terms, are convertible into shares of Common Stock of the
Company, or (c) warrants,  options or rights which are exercisable for shares of
Common Stock of the Company,  excluding,  however, warrants or options issued to
key  employees,  advisors  and  other  consultants  in the  ordinary  course  of
business,  or options,  warrants or stock disclosed in the Form S-1 as effective
(all of the foregoing  referred to herein as "Other Common Stock  Equivalents"),
in each case, and such instruments are actually  converted at a conversion price
which shall be lower than the  Conversion  Price set forth in the Notes  offered
hereby,  the Conversion  Price for such time period set forth in the Notes shall
be  automatically  adjusted  and  amended to be equal to the terms of the lowest
conversion price provided for in the instruments  governing the issuance of such
Other Common Stock Equivalents.

The  parties  agree that the purpose of  paragraph  10 of this  Agreement  is to
protect the Investors  under this Agreement  against the Company  issuing "cheap
stock" to anyone during the one hundred twenty (120) days following the closing.
Further,  it is agreed that it is not the intent of paragraph 10 to preclude the
Company  from seeking  additional  capital  through the  issuance of  additional
equity or debt in the
<PAGE>
Company.  The parties  specifically  agree that to the extent the Company issues
any equity or debt during such one hundred twenty (120) day period following the
closing under substantially  similar terms and conditions and with substantially
similar  formulae  relative to conversion,  that it is not the intention of this
Paragraph  10 that the  Company  will be required  to  automatically  adjust the
Investor's  Conversion  price to a lower conversion price merely because someone
has  elected to convert on a  different  date and has had the  opportunity  of a
different result by virtue of such election.  The parties  recognize the Company
can  control  the  price at which it  issues  equity  or debt or the  terms  and
conditions of conversion,  if applicable;  however the parties further recognize
that by virtue of the fluctuations in the market,  both another closing date and
another  election to convert date may result in a lower price,  which prices are
generally outside the Company's control.

11.      EXCHANGE OF NOTES.

At the request of any holder of any Note and upon surrender of any such Note for
such purpose to the Company at its principal office,  the Company at its expense
will  issue  in  exchange   therefor  a  new  Note,  in  such   denomination  or
denominations  and  payable  to the  order  of such  payee or  payees  as may be
requested,  dated the date to which  interest  has been paid on the  surrendered
Note, in an aggregate  principal  amount equal to the  principal  balance of the
surrendered Note. Such new Note shall be in the form of the surrendered Note.

12.       REPLACEMENT OF NOTES

Upon  receipt of evidence  reasonably  satisfactory  to the Company of the loss,
theft,  destruction or mutilation of any Note and, in the case of any such loss,
theft or  destruction,  upon delivery of an indemnity bond by the holder in such

                        Litigation, Proceedings: Defaults

A requirement  of the funding  provided to the Company on November 15, 1997 from
Avalon  was that  the  Company  would  file its  registration  statement  within
forty-five (45) days of the funding.  The Form S-1 was filed on January 8, 1998,
however,  this eight (8) day  lateness  was waived by the Avalon  investors.  In
addition, the Company had agreed to use its best effort to have its registration
declared effective within one hundred twenty (120) days of the November 15, 1997
closing.

The Company  believes that it has used its best efforts to have its registration
declared  effective.  The Avalon agreements  required that in the event that the
registration  statement was not effective  within one hundred twenty (120) days,
that the  Company  would pay as  liquidated  damages  an  amount  equal to three
percent  (3%) of the  aggregate  amount  of the  notes per  month.  The  initial
comments and the  comments to the Amended  Form S-1 have  delayed  registration.
While  most  of the  comments  received  on the  Amended  Form  S-1  are  purely
accounting  matters  which the Company  believes  have now been  resolved,  as a
result of the delay in  registration,  pursuant  to the Avalon  agreements,  the
Avalon  investors  are due $129,999 for the months of April,  May and June.  The
Company intends to use a part of the proceeds from this  transaction to cure the
default in the payment of such liquidated damage payments.
<PAGE>
In the Kingsbridge agreements,  the Company had agreed to use its best effort to
have its  registration  declared  effective within ninety (90) days of the March
23, 1998 closing. The Company believes that it has used its best efforts to have
its registration declared effective. The Kingsbridge agreements required that in
the event that the  registration  statement was not effective within such ninety
(90)  period,  that the Company  would be required to make a lump sum payment in
the amount of $10,000  within  three (3) trading  days of the date by which such
registration statement was required to have been declared effective. Such ninety
(90)  period  ended on June 21,  1998.  Said sums are due and owing on or before
June 24,  1998.  The  Company  intends to use a part of the  proceeds  from this
transaction to make such payment.

                      Absence of Certain Changes or Events

To the extent of changes in the  Company's  accounting  disclosure,  the Company
believes  that the  restatement  of the  financial  position  of the  Company is
material  relative  to all SEC  reports  since  June 30,  1997 and that such SEC
reports must be amended to the extent of the planned revisions disclosed herein.

There is no claim,  action proceeding or litigation  pending or threatened which
has not been disclosed in an SEC Report.

in cash on _____________,  2000 (the "Maturity Date");  provided,  however, that
the Company may, at its sole option, by written notice given to the Payee at any

amount of this Note on the Prepayment  Date (as defined herein) by delivering to
the Payee  such  number of shares  of Common  Stock of the  Company  as shall be

principal  amount equal to all accrued and unpaid  interest due on such Interest
Payment Date (the "Additional  Note").  All reference herein to the "Note" shall
mean and include each Additional  Note delivered by the Company  pursuant to the
provisions  hereof. In addition,  and in lieu or paying interest on this Note in

terms shall be made expressly subject and subordinated to this Note.

4.     PREPAYMENT OF NOTE.

(a) Subject at all times to the holder's  right to convert all or any portion of

option of the Company, upon not less than ten (10) days' prior written notice to
the holder of this Note (the "Prepayment  Notice"),  in whole or in part without
premium  or  penalty at any time or from time to time from and after the date of
the initial issuance of the Note (the "Issuance Date").

(b) Each Prepayment  Notice shall specify the principal  amount of this Note and
all other outstanding  Notes to be redeemed and the applicable  Prepayment Date.
Each prepayment of principal of this Note shall be accompanied by the payment of
all interest accrued and unpaid to the prepayment date on the amount so prepaid.
Each such  prepayment  shall be made by wire transfer of  immediately  available
funds or by bank  cashier's  check  payable  to the Payee and shall be on a date
(the  "Prepayment  Date") which shall be not earlier than five (5) business days
following  delivery of the Note by the holder.  Any partial  prepayment  of this
Note,  whether  optional  or  mandatory,  shall be applied  first to accrued and

transfer funds within the time provided herein, the Company shall be required to
pay the holder a sum equal to two (2%)  percent per month until such  prepayment

Section 4 hereof,  the holders of the Notes shall have the following  conversion
rights (the "Conversion Rights"):

30th day  following  the  Issuance  Date,  the  holder of this Note may elect to

principal  amount of this Note,  (ii) an  additional  thirty three and one-third
(33-1/3%) percent of the original principal amount of this Note may be converted

percent of the  original  principal  amount of this Note,  into shares of Common
Stock of the Company,  by written notice given to the Company in accordance with
the provisions of Section 5(h) hereof (the "Conversion Notice"). In no event may
the  holder of this Note  effect a  conversion  of less than  $10,000  principal
amount of this Note. Subject to the foregoing, the holder of this Note may elect
to convert (a "Voluntary Conversion") all or any portion of the principal amount
of this Note held by such person  into a number of fully paid and  nonassessable
shares of Common Stock equal to the quotient  which results when the  Conversion
Price (as defined  below) in effect as of the date of the  Conversion  Notice is
divided into the aggregate  principal  amount of all or any portion of this Note
outstanding  plus all accrued but unpaid  interest  thereof to be so  converted.
Such right of  Voluntary  Conversion  shall be effected by the  surrender of the
Note to be converted to the Company within one (1) business days of transmission

stamps or funds therefore, if required pursuant to Section 5(g) herein.

(b) Automatic  Conversion.  Prior to _____, 2000, the Company shall not have the
right to compel any holder of Note to convert such Note into Common Stock or any
other securities of the Company.  Effective as of _________, 2000, to the extent
not previously  converted by the holders, all remaining principal amount of this
Note, together with all accrued interest hereon, shall automatically and without
further  action on the part of such holders,  be converted  into Common Stock of
the Company at the Conversion Price then in effect.
<PAGE>
(c)  Conversion  Price.  Subject to adjustment  from time to time as provided in
Section 5(d) below, the term "Conversion Price" shall mean the lowest of:

         (ii) the  product of  multiplying  (A) the  average of the  Closing Bid
Price for the five consecutive trading days preceding the applicable date of the

the "Pink Sheets",  as the case may be, for the applicable number of consecutive
trading days immediately preceding the Issuance Date, the date of the Conversion

         (i) Adjustments for Stock Splits and Combinations. If the Company shall
at any time or from time to time after the Issuance  Date,  effect a stock split
of the  outstanding  Common Stock,  the  applicable  Conversion  Price in effect
immediately prior to the stock split shall be  proportionately  decreased (or in
increased in the case of a reverse stock split).  If the Company  shall,  at any
time or from time to time  after the  Issuance  Date,  combine  the  outstanding
shares of Common Stock, the applicable  Conversion  Price in effect  immediately
prior to the combination  shall be  proportionately  increased.  Any adjustments
under this  Section  5(d)(i)  shall be effective at the close of business on the
date the stock split or combination occurs.

         (ii)  Adjustments  for  Certain  Dividends  and  Distributions.  If the
Company shall at any time or from time after the Issuance Date, make or issue or
set a record date for the  determination  of holders of Common Stock entitled to
receive a dividend  or other  distribution  payable  in shares of Common  Stock,
then, and in each event, the applicable  Conversion Price in effect  immediately
prior to such event shall be  decreased  as of the time of such  issuance or, in
the event such a record date shall have been fixed,  as of the close of business
on such record date, by multiplying,  as applicable,  the applicable  Conversion
Price then in effect by a fraction;

                  (A) the numerator of which shall be the total number of shares
of Common Stock  issued and  outstanding  immediately  prior to the time of such
issuance or the close of business on such record date; and

                  (B) the  denominator  of which  shall be the  total  number of
shares of Common Stock issued and outstanding  immediately  prior to the time of
such  issuance  or the close of  business on such record date plus the number of
shares of Common Stock issuable in payment of such dividend or distribution.

         (iii) Adjustment for Other Dividends and Distributions.  If the Company
shall at any time or from time to time after the Issuance Date, make or issue or
set a record date for the  determination  of holders of Common Stock entitled to
receive a dividend or other distribution  payable in other than shares of Common
Stock, then, and in each event, an appropriate  revision to the Conversion Price
shall be made and  provision  shall be made (by  adjustments  of the  Conversion
Price  or  otherwise)  so that  the  holder  of this  Note  shall  receive  upon
conversions  thereof,  in  addition  to the  number of  shares  of Common  Stock
receivable  thereon,  the number of  securities  of the Company which they would
have received had this Note been converted into Common Stock on the date of such
event and had  thereafter,  during the period from the date of such event to and
including the  Conversion  Date,  retained such  securities  (together  with any
distributions  payable  thereon during such period),  giving  application to all
adjustments  called for during such period  under this  Section  5(d)(iii)  with
respect to the rights of the holders of the Note.

         (iv) Adjustments for Reclassification, Exchange or Substitution. If the
Common Stock  issuable upon  conversion of this Note at any time or from time to
time after the Issuance Date shall be changed into the same or different  number
of  shares of any  class or  classes  of  stock,  whether  by  reclassification,
exchange,  substitution  or  otherwise  (other  than by way of a stock  split or
combination of shares or stock dividends provided for in Sections 5(d)(i),  (ii)
and  (iii),  or a  reorganization,  merger,  consolidation,  or sale  of  assets
provided for
<PAGE>
in Section  5(d)(v)),  then, and in each event,  an appropriate  revision to the
Conversion  Price shall by made and provisions  shall be made (by adjustments of
the  Conversion  Price of  otherwise) so that the holder of this Note shall have
the right  thereafter to convert such Note into the kind and amount of shares of
stock  and  other  securities   receivable  upon   reclassification,   exchange,
substitution or other change, by holders of the number of shares of Common Stock
into  which  such Note  might  have  been  converted  immediately  prior to such
reclassification, exchange, substitution or other change, all subject to further
adjustment as provided herein.

         (v) Adjustments for Reorganization,  Merger,  Consolidation or Sales of
Assets.  If at any time or from time to time after the Issuance Date there shall
be a capital  reorganization  of the Company (other than by way of a stock split
or combination  of shares or stock  dividends or  distributions  provided for in
Section 5(d)(i), (ii) and (iii), or a reclassification, exchange or substitution
of shares provided for in Section 5(d)(iv)), or a merger or consolidation of the
Company with or into another  corporation,  or the sale of all or  substantially
all of the Company's properties or assets to any other person, then as a part of
such reorganization,  merger, consolidation, or sale, an appropriate revision to
the Conversion  Price shall be made and provision  shall be made (by adjustments
of the Conversion Price or otherwise) so that the holder of this Note shall have
the right  thereafter to convert this Note into the kind and amount of shares of
stock  and  other  securities  or  property  of the  Company  or  any  successor
corporation resulting from such reorganization,  merger, consolidation, or sale,
to which a holder of Common Stock  deliverable  upon  conversion  of such shares
would have been entitled upon such  reorganization,  merger,  consolidation,  or
sale,  to which a holder of Common Stock  deliverable  upon  conversion  of such
shares would have been entitled upon such reorganization, merger, consolidation,
or  sale.  In any  such  case,  appropriate  adjustment  shall  be  made  in the
application of the provisions of this Section 5(d)(v) with respect to the rights
of the holders of this Note after the reorganization,  merger, consolidation, or
sale to the end that the  provisions  of this  Section  5(d)(v)  (including  any
adjustment in the applicable  Conversion  Ratio then in effect and the number of
shares of stock or other  securities  deliverable  upon conversion of this Note)
shall be applied  after that event in as nearly an  equivalent  manner as may be
practicable.

         (vi)   Adjustments   after   Registration   Statement   is   Effective.
Notwithstanding  any  other  provision  contained  in  this  Section  5(d),  the
Conversion Price shall be adjusted following the effective date of the Company's
registration  statement on Form S-1 or any other  appropriate  registration form
(the "Registration Statement") filed with the Securities and Exchange Commission
("SEC") (the "Effective Date") as follows:

                  (A) for  conversions  beginning  90 days  after the  Effective
Date, the Conversion  Price shall be equal to the lower of (1) the Issuance Date
Conversion  Price;  or (2) 77.5% of the average of the Closing Bid Price for the
five (5) days trading immediately preceding the date of the Conversation Notice;
and

                  (B) for  conversions  beginning  120 days after the  Effective
Date, the Conversion  Price shall be equal to the lower of (1) the Issuance Date
Conversion  Price;  or (2) 75.0% of the average of the Closing Bid Price for the
five (5) days trading immediately preceding the date of the Conversion Notice.

(e) No  Impediment.  The Company shall not, by amendment of its  Certificate  of
Incorporation or through any reorganization,  transfer of assets, consolidation,
merger, dissolution,  issue or sale of securities or any other voluntary action,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed or performed  hereunder  by the Company,  but will at all times in good
faith, assist in the carrying out of all the provisions of this Section 5 and in
the taking of all such action as may be  necessary  or  Appropriate  in order to
protect the Conversion Rights of the holder of the Note against impairment.

(f)  Certificate  as to  Adjustments.  Upon  occurrence  of each  adjustment  or
readjustment  of the  Conversion  Price or number  of  shares  of  Common  Stock
issuable upon conversion of the Note pursuant to this Section 5, the Company, at
its  expense,   shall  promptly  compute  such  adjustment  or  readjustment  in
accordance with the terms hereof and furnish notice to each holder of such Note,
a certificate setting forth such adjustment and readjustment,  showing in detail
the facts upon which such adjustment or readjustment is based. The Company shall
furnish or cause to be furnished to such holder a like certificate setting forth
such adjustments and readjustments, the applicable Conversion Price in effect at
the time and the number of shares of Common  Stock and the  amount,  if any,  of
other  securities  or  property  which at the time  would be  received  upon the
conversion of such Note. Notwithstanding the foregoing, the Company shall not be
obligated to deliver a  certificate  unless such  certificate  would  reflect an
increase or decrease of at least one percent of such adjusted amount.
<PAGE>
(g) Issue  Taxes.  The  Company  shall  pay any and all  issue and other  taxes,
excluding  federal,  state or local income taxes, that may be payable in respect
of any issue or delivery of shares of Common  Stock on  conversion  of this Note
pursuant hereto;  provided,  however, that the Company shall not be obligated to
pay any transfer taxes  resulting  from any transfer  requested by any holder in
connection with any such conversion.

(h)  Notices  and  Delivery  of Shares.  All  notices  and other  communications
hereunder shall be in writing and shall be deemed given and effective (i) on the
same date,  if delivered  personally or by facsimile by not later than 7:00 p.m.
New York time (with a courtesy copy of such facsimile simultaneously sent by fax
to Counsel for the  Company),  or (ii) three (3) business days  following  being
mailed  by  certified  or  registered  mail,  postage  prepaid,   return-receipt
requested,  addressed  to the holder of record at its address  appearing  on the
books  of  the  Company.  The  Company  shall,  immediately  upon  receipt  of a
Conversion  Notice,  issue  and  deliver  to or upon the  order of such  holder,
against  delivery  of the Notes  which have been  converted,  a  certificate  or
certificates for the number of shares of Common Stock to which such holder shall
be entitled and such certificate or certificates  shall not bear any restrictive
legend; provided, (i) the Common Stock evidenced thereby are sold pursuant to an
effective  registration  statement  under the  Securities  Act,  (ii) the holder
provides the Company  with an opinion of counsel  reasonably  acceptable  to the
Company  to the effect  that a public  sale of such  shares may be made  without
registration under the Securities Act, or (iii) such holder provides the Company
with  reasonable  assurance that such shares can be sold free of any limitations
imposed by Rule 144,  promulgated  under the  Securities  Act. The Company shall
cause such  issuance and delivery to be effected  within three (3) business days
and shall transmit the certificates by messenger or overnight  delivery service,
or via the DWAC system,  to reach the address  designated  by such holder within
three (3) business days after the receipt of such notice.

(i) Fractional Shares. No fractional shares of Common Stock shall be issued upon
conversion  of the Note.  In lieu of any  fractional  shares to which the holder
would otherwise be entitled,  the Company shall pay cash equal to the product of
such  fraction  multiplied  by the  average  trade  price  of one  share  of the
Company's Common Stock on the applicable Conversion Date.

(j) Reservation of Common Stock. The Company shall at all times reserve and keep
available,  out of its authorized but unused shares of Common Stock,  solely for
the purpose of  effecting  the  conversion  of the Notes,  200% of the number of
shares   deliverable  upon  conversion  of  all  the  Note  from  time  to  time
outstanding.  The  Company  shall,  from  time to time in  accordance  with  the
Colorado General Corporations Law, as amended, increase the authorized number of
shares of Common  Stock if at any time the unused  number of  authorized  shares
shall not be sufficient to permit the  conversion of all of the Note at the time
outstanding.  In such  connection,  the Company shall hold a special  meeting of
stockholders  for the purpose of authorizing  additional  shares of Common Stock
not  later  than  120  days  after  any date in which  the  Company  shall  have
insufficient shares of Common Stock so reserved.

(k)  Retirement  of Note.  Conversion  of this Note shall be deemed to have been
effected on the  applicable  Conversion  Date.  The  converting  holder shall be
deemed  to have  become a  stockholder  of  record  of the  Common  Stock on the
applicable  Conversion Date. Upon conversion of only a portion of this Note, the
Company  shall issue and  deliver to such holder at the expense of the  Company,
against receipt of the original note delivered for partial  cancellation,  a new
Note representing the unconverted portion of this Note so surrendered.

(l) Regulatory Compliance.  If any shares of Common Stock to be reserved for the
purpose of  conversion  of this Note  require  registration  or listing  with or
approval of any government  authority,  stock exchange or other  regulatory body
under any federal or state law or regulation or otherwise before such shares may
be validly issued or delivered upon  conversion,  the Company shall, at its sole
cost and expense,  in good faith and as expeditiously  as possible,  endeavor to
secure such registration, listing or approval, as the case may be.

(m) Limitations on Amount of Conversion.  Notwithstanding  anything contained in
this Note to the  contrary,  in no event shall any holder of Note be entitled or
required to convert  this Note in excess of that number of shares of Note which,
upon  giving  effect to such  conversion,  would cause the  aggregate  number of
shares of Common Stock  beneficially  owned by the holder and its  affiliates to
exceed 4.9% of the outstanding  shares of the Company's Common Stock immediately
following such conversion.  For purposes of the foregoing proviso, the aggregate
number of  shares  of Common  Stock  beneficially  owned by the  holder  and its
affiliates  shall  include the number of shares of Common  Stock  issuable  upon
conversion of this Note with respect to which the  determination of such proviso
is being  made,  but shall  exclude  the number of shares of Common  Stock which
would be  issuable  upon  (i)  conversion  of the  remaining,  unconverted  Note
beneficially owned by
<PAGE>
such  holder  and  its  affiliates,  and  (ii)  exercise  or  conversion  of the
unexercised or unconverted  portion of any other securities of the Company which
are beneficially owned by the holder and its affiliates and which are subject to
a limitation  on conversion or exercise  analogous to the  limitation  contained
herein.  Except as set forth in the  preceding  sentence,  for  purposes of this
paragraph,  beneficial  ownership shall be calculated in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended. Any holder of Note may
waive the foregoing limitations set forth in this paragraph by written notice to
the Company  upon not less than 30 days prior  notice  (with such waiver  taking
effect only upon the expiration of such 30-day notice period).

(n) In the event the  Company  does not make  delivery  of the  certificates  of
Common Stock, as instructed by a holder, within five (5) business days after the
Date of  Conversion,  then in such event the Company  shall pay to the holder an
amount,  in  immediately  available  funds  in  accordance  with  the  following
schedule,  wherein "No. Business Days Late" is defined as the number of business
days beyond the five (5) business days delivery period.

                                                        Late Payment for Each
Principal Amount Being                                     $10,000 of Notes
No. Business Days Late                                    Converted (U.S. $)
         1                                                    $100
         2                                                    $200
         3                                                    $300
         4                                                    $400
         5                                                    $500
         6                                                    $600
         7                                                    $700
         8                                                    $800
         9                                                    $900
         10                                                   $1,000
         11                                                   $1,000 +  $200 for
                                                          each Business Day Late
                                                          Beyond 10 days

To the extent  that the  failure of the  Company  to issue the  certificates  of
Common  Stock  pursuant to this  Section  5(n) is due to the  unavailability  of
authorized but unissued  shares of Common Stock,  the provisions of this Section
5(n) shall not apply but instead the provisions of Section 5(o) shall apply. The
Company shall pay any payments  incurred  under this Section 5(n) in immediately
available  funds within five (5) business  days from the date of issuance of the
certificates of applicable  Common Stock.  Nothing herein shall limit a holder's
right to pursue actual  damages for the  Company's  failure to issue and deliver
Common  Stock to the holder  within  three (3)  business  days after the Date of
Conversion.

         (o) If, at any time, a holder  submits a Notice of  Conversion  and the
Company does not have sufficient  authorized but unissued shares of Common Stock
available to effect, in full, a conversion of the Notes (a "Conversion Default,"
the date of such default  being  referred to herein as the  "Conversion  Default
Date"), the Company shall issue to the holder a certificate  representing all of
the shares of Common Stock which are available,  and the Notice of Conversion as
to any Notes  requested  to be converted  but not  converted  (the  "Unconverted
Notes") shall become null and void.  The Company  shall  provide  notice of such
Conversion  Default  ("Notice of Conversion  Default" to all existing holders of
outstanding  Notes,  by  facsimile,  within one (1) business day of such default
(with the original  delivered by  overnight or two day  courier).  No holder may
submit a Notice of  Conversion  after  receipt of Notice of  Conversion  Default
until the date additional  shares of Common Stock are authorized by the Company.
The Company  agrees to pay to all holders of  outstanding  Notes  payments for a
Conversion  Default  ("Conversion  Default  Payments") in the amount of (N/365 x
(.24) x the initial issuance price of the outstanding  Notes held by each holder
where N = the number of days from the  Conversion  Default Date to the date (the
"Authorization  Date") that the Company authorizes a sufficient number of shares
of Common Stock to affect  conversion of all remaining  Notes. The Company shall
send notice  ("Authorization  Notice") to each holder of outstanding  Notes that
additional shares of Common Stock have been authorized,  the Authorization  Date
and the amount of holder's  accrued  Conversion  Default  Payments.  The accrued
Conversion  Default shall be paid in immediately  available  funds,  or shall be
convertible  into Common Stock at the Conversion  Rate, at the holder's  option,
payable  as  follows:  (i) in the event  holder  elects to take such  payment in
immediately   available  funds,  payments  shall  be  made  to  such  holder  of
outstanding  Notes by the fifth day of the following  calendar month, or (ii) in
the event holder  elects to take such  payment in stock,  the holder may convert
such payment  amount into Common Stock at the  Conversion  Rate at anytime after
the 5th day of the calendar month following the month in which the Authorization
Notice was received,  until the expiration of the Mandatory  Conversion Date (as
defined herein).

                  Nothing herein shall limit the holder's right to pursue actual
damages for the Company's  failure to maintain a sufficient number of authorized
shares of common stock.
<PAGE>
(p) Nothing  contained herein shall require the Company to issue upon receipt of
a Notice of  Conversion  in excess of 20% of its issued and  outstanding  Common
Stock as  provided in NASDAQ  Marketplace  Rule 4320 (e) (21) (H) (the "NASD 20%
Rule") unless and until the  Shareholder  Approval (as defined  herein) has been
obtained  by the  Company.  In the event the  Company  does not issue its Common
Stock after receipt of a Notice of Conversion because of the NASD 20% Rule, then
in such event the Company shall pay to the holder 133% of the principal  balance
remaining on the Notes plus all accrued  interest.  Said amount shall be paid to
the holder  within five (5) business  days of the receipt of the faxed Notice of
Conversion from holder.

6.       EVENTS OF DEFAULT.

The  occurrence and  continuance  of any one or more of the following  events is
herein referred to as an Event of Default:

(a) If the Company shall default in converting the applicable  principal  amount
of this Note into Common Stock and delivering  stock  certificates in respect of
such conversion by the Delivery Date; or

(b) If the Company  shall  default in the payment  either in cash or  Additional
Notes of any  installment  of interest on this Note when  payable in  accordance
with the terms thereof for more than ten (10) business days after the same shall

(c) If the  Company  shall not,  at the time of receipt of a  Conversion  Notice
hereunder,  have a sufficient  number of authorized  and unissued  shares of its

default  shall not have been  remedied  within sixty (60) calendar days from the
date of such Conversion Notice; or

(d) If the Company shall default in the performance of or compliance with any of
its  material  covenants or  agreements  contained  herein or in the  Securities
Purchase Agreement,  and such default shall not have been remedied within thirty
(30) calendar days after written notice thereof shall have been delivered to the
Company by the holder of this Note; or

(e) If any  representation  or  warranty  made in writing by or on behalf of the
Company  in  the  Securities  Purchase  Agreement  or  in  connection  with  the
transactions contemplated thereby shall prove to have been false or incorrect in
any material respect on the date as of which made; or

(f)  If  the  Company  or any of its  Significant  Subsidiaries  shall  make  an
assignment for the benefit of creditors, or shall admit in writing its inability
to pay its debts as they  become  due,  or shall file a  voluntary  petition  in
bankruptcy  or shall have an order for relief under the  Bankruptcy  Act granted
against it or them, or shall be  adjudicated  a bankrupt or insolvent,  or shall
file any petition or answer seeking for itself any reorganization,  arrangement,
composition, readjustment,  liquidation, dissolution or similar relief under any
present or future statute, law or regulation, or shall file any answer admitting
or not  contesting  the material  allegations  of a petition  filed  against the
Company or any of its Significant Subsidiaries in any such proceeding,  or shall
seek or consent to or acquiesce in the  appointment  of any trustee,  custodian,
receiver or liquidator of the Company or of all or any  substantial  part of the
properties of the Company or any of its Significant Subsidiaries, or the Company
or its directors shall take any action looking to the dissolution or liquidation
of the  Company or any of its  Significant  Subsidiaries.  For  purposes of this
Section  6(f),  the term  Significant  Subsidiary  shall mean and  include  Bass
American Petroleum Corp. and any other person, firm or corporation (i) more than
50% of the common stock or equity  interests of which are owned of record by the
Company or any  Subsidiary of the Company,  and (ii) the net income before taxes
or total assets of which represent more than 15% of the  consolidated net income
before taxes or consolidated  assets of the Company and all of its Subsidiaries;
of

(g) If, within sixty (60) days after the commencement of any proceeding  against
the  Company  or  any  Significant   Subsidiary   seeking  any   reorganization,
arrangement,  composition,  readjustment,  liquidation,  dissolution  or similar
relief under any present or future statute,  law or regulation,  such proceeding
shall  not have  been  dismissed,  or if,  within  sixty  (60)  days  after  the
appointment,  without  the  consent  or  acquiescence  of  the  Company  or  any
Significant Subsidiary, of any trustee, receiver or liquidator of the Company or
any Significant  Subsidiary or of all or any substantial  part of the properties
of the Company or any Significant  Subsidiary,  such appointment  shall not have
been vacated.

(h) The Company  shall have its Common Stock  suspended or delisted from trading
on the NASDAQ SmallCap  market.  Then, or any time  thereafter,  and in each and
every such case,  unless such Event of Default shall have been waived in writing
by the holder (which waiver
<PAGE>
shall not be deemed to be a waiver of any  subsequent  default) at the option of
the holder and in the holder's  sole  discretion,  the holder may consider  this
Note immediately due and payable without presentment,  demand, protest or notice
of any kinds,  all of which are hereby expressly  waived,  anything herein or in
any note or other instruments contained to the contrary notwithstanding, and the
holder may  immediately  enforce any and all of the holder's rights and remedies
provided herein or any other rights or remedies afforded by law.

7.       REMEDIES ON DEFAULT; ACCELERATION.

Upon the  occurrence  and during the  continuance  of an Event of  Default,  the
entire  unpaid  balance of  principal  and accrued  interest on this Note may be
accelerated and declared to be immediately due and payable by the Payee. Whether
or not the Notes is accelerated or declared to be immediately due and payable by
the Payee,  the  Company  agrees to pay the maximum  rate of interest  permitted
under New York law from the date any payment of  principal  and/or  interest was
due until the date payment of such amount is actually made. Unless waived by the
written  consent  of persons  holding  66-2/3 % or more in  aggregate  principal
amount  of the  Notes  of the  Company  issued  under  the  Securities  Purchase
Agreement (including the Payee), the Payee and other holders of any of the Notes
at the time  outstanding  may  proceed to protect and enforce the rights of such
holder  by an action at law,  suit in  equity or other  appropriate  proceeding,
whether for the specific  performance of any agreement  contained herein, or for
an injunction  against a violation of any of the terms hereof,  or in aid of the
exercise  of any power  granted  hereby  or by law.  In the event of an Event of
Default,  the  Company  agrees to pay to the  holder  of this Note such  further
amount as shall be  sufficient  to cover  the cost and  expense  of  collection,
including,  without  limitation,  reasonable  attorneys'  fees and  expenses and
reasonable  costs of  investigation.  If the  holder of any Note  shall give any
notice or take any action in  respect of a claimed  default,  the  Company  will
forthwith  give  written  notice  thereof to the holder of this Note at the time
outstanding  describing  the  notice or  action  and the  nature of the  claimed
default.  No course of  dealing  and no delay on the part of the  holder of this
Note or the holder of any other Note in  exercising  any right,  power or remedy
shall operate as a waiver thereof or otherwise  prejudice such holder's  rights,
powers and remedies.  No right, power or remedy conferred hereby upon the holder
hereof shall be exclusive of any other right, power or remedy referred to herein
nor now or hereafter available at law, in equity, by statute or otherwise.

(8)      WAIVER OF PRESENTMENT; MAXIMUM RATE OF INTEREST.

(a) The Company and each surety,  endorser,  and guarantor or other party liable
for the payment of any sums of money  payable on this Note  severally  waive all
demands for payment,  presentations for payment, notices of dishonor, notices of
intention to accelerate maturity, notices of acceleration of maturity, protests,
and notices of protest, to the extent required by law.

(b) It is  expressly  stipulated  and agreed to be the intent of the Company and
the  holders  of this  Note at all  times  to  comply  with the  applicable  law
governing  the maximum  rate of interest  payable on or in  connection  with all
indebtedness and transactions hereunder (or applicable United States federal law
to the extent  that it permits  holders of this Note to  contract  for,  charge,
take, reserve or receive a greater amount of interest). If the applicable law is
ever  judicially  interpreted  so as to render  usurious  any amount of money or
other  consideration  called for hereunder,  or contracted for, charged,  taken,
reserved  or  received  with  respect  to any loan or advance  hereunder,  or if
acceleration of the maturity of the Note or the indebtedness hereunder or if any
prepayment by the Company  results in the Company's  having paid any interest in
excess of that  permitted by law, then it is the Company's and holders'  express
intent that all excess cash amounts theretofore  collected by holder by credited
on the principal balance of this Note (or if this Note has been or would thereby
be paid in full,  refunded  to the  Company),  and the  provisions  of this Note
immediately be deemed reformed and the amounts thereafter  collectible hereunder
reduced,  without the necessity of the  execution of any new document,  so as to
comply with the applicable  law, but so as to permit the recovery of the fullest
amount otherwise called for hereunder.  The right to accelerate maturity of this
Note  does not  include  the  right to  accelerate  any  interest  which has not
otherwise accrued on the date of such  acceleration,  and holder does not intend
to collect any unearned interest in the event of acceleration.

9.       NOTICES.

All notices,  requests, demands or other communications under this Note shall be
given in the same manner as provided in the Securities Purchase Agreement.

10.      GOVERNING LAW;  RESOLUTION OF DISPUTES.

(a) This Note shall be governed by, and construed and  interpreted in accordance
with,  the laws of the State of New York,  without  giving effect to conflict of
law principles.
<PAGE>
(b) Any dispute  regarding the  interpretation or application of this Note which
cannot be settled  among the parties  shall be  resolved  in New York,  New York
final and binding arbitration in accordance with the then obtaining rules of the
American  Arbitration  Association.  There shall be appointed three arbitrators,
one of whom shall be selected by the  Company,  the second by the holder and the
third  by  mutual  agreement  of  the  parties  or by the  American  Arbitration
Association.  The decision of the arbitrators shall be final and upon the holder
and the Company and may be  enforced by the  prevailing  party or parties in any
court of  competent  jurisdiction.  Each party shall bear their own costs of the
arbitration and shall share equally the costs of the arbitrators.

11.      SUBORDINATION TO SENIOR DEBT.

(a) Payment of the  principal  of and  interest on this Note and all other Notes
issued under the Securities  Purchase  Agreement is subordinated,  to the extent
and in the manner provided  herein,  to the prior payment of all indebtedness of
the Company and/or all Subsidiaries of the Company,  for money borrowed or other
obligations which is now or may hereafter be owed (collectively,  "Senior Debt")
to any bank,  commercial  finance company,  factor,  insurance  company or other
institution the lending activities are regulated by law (individually, a "Senior
Lender" and collectively,  "Senior Lenders"), which may, hereafter on any one or
more  occasions  provide  financing  to the Company or any of its  Subsidiaries,
secured by liens on any of the assets and  properties of the Company  and/or any
of  its  Subsidiaries   (individually   and   collectively,   an  "Institutional
Borrower").

(b)  Upon  any  payment  or   distribution   of  assets  or  securities  of  the
Institutional Borrower, as the case may be, of any kind or character, whether in
cash,  property or  securities,  upon any  dissolution or winding up or total or
partial  liquidation or reorganization of the  Institutional  Borrower,  whether
voluntary or  involuntary or in bankruptcy,  insolvency,  receivership  or other
proceedings,  all amounts  payable under Senior Debt shall first be paid in full
in cash, or payment provided for in cash or cash equivalents,  before the holder
hereof  shall be entitled to receive any payment on account of  principal  of or
interest  on this Note.  Before  any  payment  may be made by the  Institutional
Borrower of the principal of or interest on this Note upon any such  dissolution
or winding up or liquidation or  reorganization,  any payment or distribution of
assets or  securities  of the  Institutional  Borrower of any kind or character,
whether in cash,  property or  securities,  to which the holder  hereof would be
entitled,  except for the  provisions  of this  Section 11, shall be made by the
Institutional  Borrower or by any receiver,  trustee in bankruptcy,  liquidating
trustee, agent or other person making such payment or distribution,  directly to
the holders of Senior Debt or their  representatives  to the extent necessary to
pay all such Senior Debt in full after giving effect to any  concurrent  payment
or distribution to the holders of such Senior Debt.

(c) Upon the happening of any default in payment of the principal of or interest
on any Senior Debt, then, unless and until such default shall have been cured or
waived or shall have  ceased to exist,  no direct or  indirect  payment in cash,
property or securities,  by set-off or otherwise,  shall be made or agreed to be
made by the Institutional Borrower on account of the principal of or interest on
this Note.

(d) Upon the  happening of an event of default  (other than under  circumstances
when the terms of Section 11(c) above are applicable) with respect to any Senior
Debt  pursuant to which the holder  thereof is entitled  under the terms of such
Senior Debt to accelerate the maturity thereof,  and upon written notice thereof
given to each of the Institutional  Borrower and the holder of this Note by such
holder of Senior Debt ("Payment  Notice"),  then, unless and until such event of
default shall have been cured or waived or shall have ceased to exist, no action
shall or may be taken for  collection  of any  amounts  under this Note,  and no
direct or  indirect  payment  in cash,  property  or  securities,  by set-off or
otherwise,  shall be made or agreed to be made by the Institutional  Borrower an
account of the  principal of or interest on this Note until such Senior Debt has
been paid in full accordance with its terms.

(e) In the event than,  notwithstanding  the  provisions of this Section 11, any
payment shall be made on account of the principal of or interest on this Note in
contravention  of such  provisions,  then  such  payment  shall  be held for the
benefit of, and shall be paid over and  delivered to, the holders of such Senior
Debt  remaining  unpaid to the extent  necessary to pay in full the principal of
and  interest  on such  Senior Debt in  accordance  with its terms after  giving
effect to any concurrent  payment or  distribution to the holders of such Senior
Debt.

(f) Nothing  contained in this Section 11 shall (i) impair the conversion rights
of the holder hereof referred to in Section 5 above, (ii) impair, as between the
Company and the holder of this Note,  the  obligation  of the Company,  which is
absolute and  unconditional,  to pay to the holder hereof principal and interest
as the same shall become due and  payable,  or (iii)  prevent the holder  hereof
from exercising all rights,  powers and remedies  otherwise  provided herein, in
the  Securities  Purchase  Agreement  or by  applicable  law, all subject to the
express limitations provided herein.
<PAGE>
(g) Upon the occurrence of an Event of Default, if any Senior Debt shall then be
outstanding,  no  acceleration  of the  maturity of this Note shall be effective
until the earlier of (i) ten (10) days shall have passed  following  the date of
delivery to the  Institutional  Borrower by a Senior Lender(s) of written notice
of acceleration of any Senior Debt, or (ii) the maturity of any then outstanding
Senior  Debt  shall have been  accelerated  by reason of a default  hereon.  The
Company may pay the holder  hereof any  defaulted  payment and all other amounts
due following any such acceleration of the maturity of this Note if this Section
11 would not prohibit such payment to be made at that time.

(h) Upon  payment  in full of all Senior  Debt,  the Payee of this Note shall be
subrogated  to the rights of the holder or holders of Senior Debt to receive all
payments or  distributions  applicable on Senior Debt to the extent of the prior
application  thereto of moneys or other assets which would have been received in
respect  of this  Note,  but  for  these  subordination  provisions,  until  the
principal of, and interest on, this Note shall have been paid in full.

(i) The Payee, by accepting this Note (A) shall be bound by all of the foregoing
subordination  provisions;  and (B)  agrees  expressly  for the  benefit  of the
present  and  future  holders  of Senior  Debt that this Note is  subject to the
foregoing subordination provisions.

(j) The  foregoing  subordination  provisions  shall be for the  benefit  of all
holders of Senior Debt from time to time  outstanding,  and each of such holders
may proceed to enforce such provisions either directly against the holder hereof
or in any other manner provided by law.

(k)  Notwithstanding  anything to the contrary set forth in this Section 11, the
interest  of the  holder of this Note (as  specified  in  Section  12 hereof) is
subject and  subordinated  only to the first lien and  security  interest of any
holder of Senior Debt of the Company, unless otherwise expressly consented to in
writing by the Payee.

12.      SUCCESSORS AND ASSIGNS.

This Note shall be binding  upon and inure to the benefit of the Company and the
holder hereof and their respective  successors and assigns;  provided,  however,
that the  Company may not  transfer  or assign any of its rights or  obligations
hereunder without the prior written consent of the holder hereof.

13.      UNENFORCEABLE PROVISIONS.

If any provision of this Note is invalid, illegal or unenforceable,  the balance
of this Note shall remain in effect, and if any provision is inapplicable to any
person or circumstance,  it shall  nevertheless  remain  applicable to all other
persons and circumstances.

IN WITNESS WHEREOF,  the Company has caused this Note to be executed by its duly
authorized officers as of the date first set forth above.

Environmental Remediation Holding Corporation, a Colorado corporation (the
"Company"), and J.P. Carey Securities, Inc., a Georgia corporation
(hereinafter referred to as "J.P. Carey").

                              W I T N E S S E T H:

     WHEREAS, J.P. Carey has assisted the Company in connection with the
Company's offering (the "Offering") of up to $3,000,000 in principal amount

     WHEREAS, the Warrants issued pursuant to this Agreement are being issued by
the Company to J.P. Carey and/or its  designees,  in  consideration  for, and as
part of the  compensation  to be paid in connection  with,  the services of J.P.
Carey in connection with the Offering;

     NOW, THEREFORE, in consideration of the premises, the agreements herein set
forth and other good and valuable consideration,  the receipt and sufficiency of
which are hereby acknowledged, the parties hereto agree as follows:

1.       Grant.

         J.P.  Carey  and/or  its  designees  are  hereby  granted  the right to
purchase, at any time from the date of issuance of the aforementioned Debentures
until 5:00 P.M.,Eastern Standard Time, on __________________, 2003 (the "Warrant
Exercise Term"),  ___________ Shares at an exercise price (subject to adjustment
as provided in Article 7 hereof) of 100% of the Closing Bid Price (as defined in
the Company's  Certificate of Designations,  Preferences and Rights filed by the
Company in  connection  with the Offering) of the  Company's  Common Stock,  par
value $.0001 per share on the last business day immediately prior to the date of
closing of the  Offering,  which is equal to  $0._____  per share (the  "Initial
Exercise Price").

2.       Warrant Certificates.

                  The warrant certificates (the "Warrant Certificates) delivered
and to be delivered pursuant to this Agreement shall be in the form set forth as
Exhibit  A,  attached  hereto  and made a part  hereof,  with  such  appropriate
insertions,  omissions,  substitutions  and  other  variations  as  required  or
permitted by this Agreement.

3.       Exercise of Warrants.

         3.1 Cash  Exercise.  The Exercise Price may be paid in cash or by check
to the order of the Company,  or any  combination  of cash or check,  subject to
adjustment  as  provided  in Article 7 hereof.  Upon  surrender  of the  Warrant
Certificate  with the  annexed  Form of  Election  to  Purchase  duly  executed,
together  with payment of the Exercise  Price (as  hereinafter  defined) for the
Shares purchased,  at the Company's executive offices currently located at Suite
321, 420 Jerico Turnpike,  Jerico,  New York 11753,  the registered  holder of a
Warrant  Certificate  ("Holder"  or  "Holders")  shall be  entitled to receive a
certificate or  certificates  for the Shares so purchased.  The purchase  rights
represented  by each Warrant  Certificate  are  exercisable at the option of the
Holder  hereof,  in whole or in part  (but not as to  fractional  shares  of the
Common  Stock).  In the  case of the  purchase  of  less  than  all  the  Shares
purchasable under any Warrant Certificate, the Company shall cancel said Warrant
Certificate  upon the  surrender  thereof  and shall  execute  and deliver a new
Warrant  Certificate  of like tenor for the  balance  of the Shares  purchasable

this Section 3.2, by  surrendering  this Warrant at the principal  office of the
company or at the office of its transfer agent,  accompanied by a notice stating
such  Holder's  intent  to  effect  such  exchange,  the  number of Shares to be
exchanged and the date on which the Holder  requests that such Warrant  Exchange
occur (the "Notice of Exchange").  The Warrant  Exchange shall take place on the
date  specified in the Notice of Exchange  or, if later,  the date the Notice of
Exchange is received by the Company (the "Exchange Date").  Certificates for the
Shares issuable upon such Warrant Exchange and, if applicable,  a new warrant of
like  tenor  evidencing  the  balance of the  Shares  remaining  subject to this
Warrant,  shall be issued as of the  Exchange  Date and  delivered to the Holder
within seven (7) business days following the Exchange  Date. In connection  with
any Warrant  Exchange,  this Warrant shall  represent the right to subscribe for
and acquire the number of Shares (rounded to the next highest  integer) equal to
(i) the number of Shares  specified by the Holder in its Notice of Exchange (the
"Total Number") less (ii) the number of Shares equal to the quotient obtained by
dividing  (A) the  product of the Total  Number and the then  existing  Exercise
Price by (B) the current market value of a share of Common Stock.
<PAGE>

     Upon the exercise of the  Warrants,  the issuance of  certificates  for the
Shares  shall be made  forthwith  (and in any event  within five  business  days
thereafter) without charge to the Holder thereof including,  without limitation,
any tax which may be  payable  in  respect  of the  issuance  thereof,  and such
certificates shall be issued in the name of, or in such names as may be directed
by,  the  Holder  thereof;  provided,  however,  that the  Company  shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any such  certificates in a name other than that
of the Holder and the Company  shall not be  required  to issue or deliver  such
certificates  unless or until the  person or  persons  requesting  the  issuance
thereof  shall  have paid to the  Company  the  amount of such tax or shall have
established to satisfaction of the Company that such tax has been paid.

         The Warrant  Certificates and the certificates  representing the Shares
shall be executed on behalf of the Company by the manual or facsimile  signature
of the  present  or any  future  Chairman  or  Vice  Chairman  of the  Board  of
Directors, Chief Executive officer or President or Vice President of the Company
under its  corporate  seal  reproduced  thereon,  attested  to by the  manual or
facsimile  signature  of  the  present  or any  future  Secretary  or  Assistant
Secretary  of the  Company.  Warrant  Certificates  shall be  dated  the date of
execution by the Company upon initial issuance, division, exchange, substitution
or transfer.

         The Warrant Certificates and, upon exercise of the Warrants, in part or
in whole, certificates representing the Shares shall bear a legend substantially
similar to the following:

         statement  under the Act,  (ii) to the extent  applicable,  pursuant to
         Rule 144 under the Act (or any similar  rule under such Act relating to
         the  disposition  of  securities),  or (iii) upon the  delivery  by the
         holder to the Company of an opinion of counsel, reasonably satisfactory
         to counsel to the issuer,  stating that an exemption from  registration
         under such Act is available.

5.       Price.

         5.1 Adjusted  Exercise Price. The adjusted  Exercise Price shall be the
price which shall result from time to time from any and all  adjustments  of the
Initial Exercise Price in accordance with the provisions of Article 7 hereof.

         5.2     Exercise Price. The term "Exercise Price" herein shall mean the
Initial Exercise Price or the adjusted Exercise Price, depending upon the
context.

6.       Registration Rights.

         6.1      Registration Under the Securities Act of 1993.

The  Warrants  and the Shares have not been  registered  for  purposes of public
distribution under the Securities Act of 1933, as amended ("the Act").

         6.2  Registrable  Securities.  As used  herein  the  term  "Registrable
Security" means each of the Warrants,  the Shares and any shares of Common Stock
issued  upon any  stock  split or stock  dividend  in  respect  of such  Shares;
provided,  however,  that with respect to any particular  Registrable  Security,
such security  shall cease to be a Registrable  Security when, as of the date of
determination,  (i) it has been effectively  registered under the Securities Act
and disposed of pursuant thereto,  (ii) registration under the Securities Act is
no longer  required for the immediate  public  distribution  of such security or
(iii) it has ceased to be outstanding.  The term "Registrable  Securities" means
any and/or all of the securities  falling  within the foregoing  definition of a
"Registrable   Security."   In  the   event  of  any   merger,   reorganization,
consolidation, recapitalization or other change in corporate structure affecting
the  Common  Stock,   such  adjustment  shall  be  made  in  the  definition  of
"Registrable  Security"  as is  appropriate  in order to prevent any dilution or
enlargement of the rights granted pursuant to this Article 6.

         6.3  Piggyback  Registration.  If, at any time  during  the five  years
following the date of this Agreement,  the Company  proposes to prepare and file
any registration statement or post-effective  amendments thereto covering equity
or debt securities of the Company, or any such securities of the Company held by
its  shareholders  (in any such case,  other than in  connection  with a merger,
acquisition  or pursuant to Form S-8 or successor  form),  (for purposes of this
Article 6,  collectively,  a  "Registration  Statement"),  it will give  written
notice of its  intention to do so by  registered  mail  ("Notice"),  at ten (10)
business days prior to the filing of each such  Registration  Statement,  to all
holders of the Registrable Securities. Upon the written request of such a holder
<PAGE>
(a "Requesting Holder"), made within ten (10) business days after receipt of the
Notice,  that the Company  include any of the  Requesting  Holder's  Registrable
Securities in the proposed Registration Statement, the Company shall, as to each
such Requesting  Holder,  use its best efforts to effect the registration  under
the Securities Act of the Registrable  Securities which it has been so requested
to register ("Piggyback  Registration"),  at the Company's sole cost and expense
and at no  cost  or  expense  to the  Requesting  Holders;  Notwithstanding  the
provisions  of this Section  6.3,  the Company  shall have the right at any time
after  it  shall  have  given  written  notice  pursuant  to  this  Section  6.3
(irrespective  of whether any written  request for inclusion of such  securities
shall  have  already  been  made)  to  elect  not  to  file  any  such  proposed
Registration  Statement,  or to withdraw  the same after the filing but prior to
the effective date thereof.

         6.4      Demand Registration.

                  (a) At any time, commencing ninety(90) days from the date that
the Company becomes a reporting company under the Securities and Exchange Act of
1934, as amended,  and during the Warrant  Exercise Term, any "Majority  Holder"
(as such term is defined in Section 6.4(d) below) of the Registrable  Securities
shall have the right (which right is in addition to the  piggyback  registration
rights provided for under Section 6.3 hereof),  exercisable by written notice to
the Company (the "Demand Registration Request"), to have the Company prepare and
file with the  Securities and Exchange  Commission  (the  "Commission"),  on one
occasion, at the sole expense of the Company, a Registration  Statement and such
other documents,  including a prospectus, as may be necessary (in the opinion of
both counsel for the Company and counsel for such Majority Holder),  in order to
comply with the  provisions  of the Act, so as to permit a public  offering  and
sale  of the  Registrable  Securities  by the  holders  thereof,  for  nine  (9)
consecutive months.

                  (b) The Company covenants and agrees to give written notice of
any Demand  Registration  Request to all holders of the  Registrable  Securities
within ten (10) days from the date of the  Company's  receipt of any such Demand
Registration  Request.  After  receiving  notice from the Company as provided in
this Section 6.4(b),  holders of Registrable  Securities may request the Company
to include  their  Registrable  Securities in the  Registration  Statement to be
filed  pursuant  to Section  6.4(a)  hereof by  notifying  the  Company of their
decision to include such securities  within twenty (20) days of their receipt of
the Company's notice.

                  (c) In addition to the registration  rights provided for under
Section  6.3 and  subsection  (a) of this  Section  6.4,  at any time during the
Warrant  Exercise Term, any Majority Holder (as defined below in Section 6.4(d))
of Registrable  Securities shall have the right,  exercisable by written request
to the Company, to have the Company prepare and file with the Commission, on one
occasion in respect of all holders of  Registrable  Securities,  a  Registration
Statement  so as to  permit  a  public  offering  and  sale of such  Registrable
Securities for nine (9) consecutive months,  provided,  however,  that all costs
incident  thereto  shall be at the  expense of the  holders  of the  Registrable
Securities included in such Registration  Statement.  If a Majority Holder shall
give  notice to the Company at any time of its or their  desire to exercise  the
registration right granted pursuant to this Section 6.4(c), then within ten (10)
days after the Company's  receipt of such notice,  the Company shall give notice
to the other holders of Registrable  Securities,  advising them that the Company
is  proceeding  with such  registration  and  offering  to include  therein  the
Registrable  Securities of such holders,  provided they furnish the Company with
such  appropriate  information  in  connection  therewith  as the Company  shall
reasonably request in writing.

                  (d) The term  "Majority  Holder" as used in this  Section  6.4
shall mean any holder or any  combination of holders of Registrable  Securities,
if included in such holders, Registrable Securities are that aggregate number of
Shares  (including  Shares  already issued and Shares  issuable  pursuant to the
exercise  of  outstanding  Warrants)  as  would  constitute  a  majority  of the
aggregate number of Shares  (including Shares already issued and Shares issuable
pursuant  to  the  exercise  of  outstanding  Warrants)  included  in all of the
Registrable Securities.

         6.5      Covenants of the Company With Respect to Registration.  The
Company covenants and agrees as follows:


                  (a) In  connection  with any  registration  under  Section 6.4
hereof,  the Company shall file the  Registration  Statement as expeditiously as
possible, but in no event later than thirty (30) business days following receipt
of any demand therefor, shall use its best efforts to have any such Registration
Statements  declared  effective at the earliest possible time, and shall furnish
each  holder of  Registrable  Securities  such number of  prospectuses  as shall
reasonably be requested.
<PAGE>
                  (b)  The  Company  shall  pay all  costs,  fees  and  expenses
(excluding  fees of holders for their counsel,  transfer taxes and  underwriting
discounts or commissions) in connection with all  Registration  Statements filed
pursuant to Sections 6.3 and 6.4(a) hereof including,  without  limitation,  the
Company's legal and accounting fees,  printing  expenses,  and blue sky fees and
expenses.  The holders of Registrable  Securities  included in any  Registration
Statement  filed pursuant to Section 6.4(c) hereof will pay all costs,  fees and
expenses in connection with such registration.

                  (c) The Company  will take all  necessary  action which may be
required in qualifying or registering the Registrable  Securities  included in a
Registration  Statement  for offering and sale under the  securities or blue sky
laws of such states as are requested by the holders of such securities.

                  (d) The Company shall  indemnify any holder of the Registrable
Securities to be sold pursuant to any Registration Statement and any underwriter
or person deemed to be an underwriter under the Act and each person, if any, who
controls such holder or underwriter or person deemed to be an underwriter within
the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange
Act of 1934,  as amended  ("Exchange  Act"),  against all loss,  claim,  damage,
expense  or   liability   (including   all  expenses   reasonably   incurred  in
investigating, preparing or defending against any claim whatsoever) to which any
of them may become subject under the Act, the Exchange Act or otherwise, arising
from such Registration  Statement to the same extent and with the same effect as
the  provisions  pursuant  to which the  Company  has  agreed to  indemnify  the
purchasers  of the Company's  Debentures  contained in the  Registration  Rights
Agreement dated of even date herewith.

                  (e) Any holder of  Registrable  Securities to be sold pursuant
to a Registration  Statement,  and its successors and assigns,  shall severally,
and not jointly,  indemnify,  the Company,  its officers and  directors and each
person, if any, who controls the Company within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange  Act,  against all loss,  claim,  damage or
expense  or   liability   (including   all  expenses   reasonably   incurred  in
investigating,  preparing or defending  against any claim  whatsoever)  to which
they may become  subject under the Act, the Exchange Act or  otherwise,  arising
from  information  furnished in writing by or on behalf of such  holder,  or its
successors or assigns, for specific inclusion in such Registration  Statement to
the same  extent and with the same  effect as the  provisions  pursuant to which
purchasers  of the  Company's  Debentures  have agreed to indemnify  the Company
contained in the Registration Rights Agreement dated of even date herewith.

                  (f) Nothing  contained in this Agreement shall be construed as
requiring any Holder to exercise his Warrants prior to the initial filing of any
Registration Statement or the effectiveness thereof.

                  (g) If the Company shall fail to comply with the provisions of
this Article 6, the Company shall,  in addition to any other  equitable or other
relief available to the holders of Registrable Securities,  be liable for any or
all incidental,  special and  consequential  damages sustained by the holders of
Registrable Securities, requesting registration of their Registrable Securities.

                  (h) Except as otherwise  provided to the contrary herein,  the
Company  shall  not  permit  the  inclusion  of any  securities  other  than the
Registrable  Securities  to be  included  in any  Registration  Statement  filed
pursuant to Section 6.4 hereof, or permit any other registration statement to be
or remain effective during the  effectiveness of a Registration  Statement filed
pursuant  to  Section  6.4  hereof,  without  the prior  written  consent of the
Majority Holders, which consent shall not be unreasonably withheld.

                  (i) The  Company  shall  deliver  promptly  to each  holder of
Registrable   Securities   participating   in  the   offering   requesting   the
correspondence  and  memoranda  described  in  this  Section  6.5(i)  and to the
managing  underwriter,   if  any,  copies  of  all  correspondence  between  the
Commission and the Company,  its counsel or auditors and all memoranda  relating
to discussions with the Commission or its staff with respect to the Registration
Statement and permit each holder of Registrable  Securities and  underwriters to
do  such  investigation,   upon  reasonable  advance  notice,  with  respect  to
information contained in or omitted from the Registration  Statement as it deems
reasonably  necessary to comply with applicable  securities laws or rules of the
National  Association  of  Securities  Dealers,  Inc. Such  investigation  shall
include access to books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors,  all to such
reasonable  extent and at such reasonable  times and as often as any such holder
of Registrable Securities or underwriter shall reasonably request.
<PAGE>
                  (j) If the Company shall enter into an underwriting  agreement
with the managing  underwriter  selected for such  underwriting,  such agreement
shall be  satisfactory  in form and  substance  to the  Company,  each holder of
Registrable  Securities  and such managing  underwriter,  and shall contain such
representations, warranties and covenants by the Company and such other terms as
are  customarily  contained  in  agreements  of that type  used by the  managing
underwriter.  The  holders  of  Registrable  Securities  shall be parties to any
underwriting  agreement  relating to an underwritten  sale of their  Registrable
Securities   and  may,   at  their   option,   require   that  any  or  all  the
representations,  warranties  and covenants of the Company to or for the benefit
of such underwriter shall also be made to and for the benefit of such holders of
Registrable  Securities.  Such holders of  Registrable  Securities  shall not be
required to make any  representations  or warranties  to or agreements  with the
Company  or the  underwriter  except  as they  may  relate  to such  holders  of
Registrable Securities and their intended methods of distribution.

7.       Adjustments of Exercise Price and Number of Shares.

         7.1      {LEFT INTENTIONALLY BLANK}

         7.2  Options,   Rights,   Warrants  and  Convertible  and  Exchangeable
Securities.  Except in the case of the Company  issuing  rights to subscribe for
shares of Common Stock  distributed to all the  shareholders  of the Company and
Holders of Warrants  pursuant to Section 7.8 hereof, if the Company shall at any
time after the date hereof issue  options,  rights or warrants to subscribe  for
shares of Common Stock, or issue any securities convertible into or exchangeable
for shares of Common Stock, (i) for a consideration  per share less than (a) the
Exercise  Price in effect  immediately  prior to the  issuance of such  options,
rights or warrants, or such convertible or exchangeable  securities,  or (b) the
Market  Price,  or (ii)  without  consideration,  the  Exercise  Price in effect
immediately prior to the issuance of such options,  rights or warrants,  or such
convertible or exchangeable securities,  as the case may be, shall be reduced to
a price  determined by making a computation in accordance with the provisions of
Section 7.1 hereof, provided that:

                  (a) The aggregate maximum number of shares of Common Stock, as
the case may be, issuable under all the outstanding options,  rights or warrants
shall be deemed to be issued  and  outstanding  at the time all the  outstanding
options,  rights or warrants were issued,  and for a consideration  equal to the
minimum purchase price per share provided for in the options, rights or warrants
at the time of issuance,  plus the consideration  (determined in the same manner
as consideration  received on the issue or sale of shares in accordance with the
terms of the Warrants),  if any, received by the Company for the options, rights
or  warrants,  and if no minimum  price is  provided in the  options,  rights or
warrants, then the consideration shall be equal to zero; provided, however, that
upon the expiration or other termination of the options,  rights or warrants, if
any thereof shall not have been exercised,  the number of shares of Common Stock
deemed to be issued and outstanding pursuant to this subsection (a) (and for the
purposes  of  subsection  (v) of Section  7.1  hereof)  shall be reduced by such
number of shares as to which options,  warrants and/or rights shall have expired
or terminated  unexercised,  and such number of shares shall no longer be deemed
to be issued  and  outstanding,  and the  Exercise  Price  then in effect  shall
forthwith be readjusted and thereafter be the price which it would have been had
adjustment been made on the basis of the issuance only of shares actually issued
or issuable upon the exercise of those  options,  rights or warrants as to which
the exercise rights shall not have expired or terminated unexercised.

                  (b) The  aggregate  maximum  number of shares of Common  Stock
issuable  upon  conversion  or  exchange  of  any  convertible  or  exchangeable
securities  shall be deemed to be issued and outstanding at the time of issuance
of  such  securities,  and  for  a  consideration  equal  to  the  consideration
(determined in the same manner as consideration received on the issue or sale of
shares of Common Stock in accordance with the terms of the Warrants) received by
the  Company  for such  securities,  plus  the  minimum  consideration,  if any,
receivable  by the Company upon the  conversion or exchange  thereof;  provided,
however,  that upon the  termination  of the right to convert or  exchange  such
convertible  or  exchangeable  securities  (whether by reason of  redemption  or
otherwise), the number of shares deemed to be issued and outstanding pursuant to
this  subsection  (b) (and for the  purpose of  subsection  (v) of  Section  7.1
hereof) shall be reduced by such number of shares as to which the  conversion or
exchange rights shall have expired or terminated unexercised, and such number of
shares shall no longer be deemed to be issued and  outstanding  and the Exercise
Price then in effect shall  forthwith be readjusted  and thereafter be the price
which it would have been had  adjustment  been made on the basis of the issuance
only of the shares  actually  issued or issuable upon the conversion or exchange
of those  convertible or  exchangeable  securities as to which the conversion or
exchange rights shall not have expired or terminated unexercised.

                  (c) If any change shall occur in the price per share  provided
for in any of the options,  rights or warrants  referred to in subsection (a) of
this Section 7.2, or in the price per share at which the securities  referred to
in  subsection  (b) of this Section 7.2 are  convertible  or  exchangeable,  the
options,  rights or warrants or conversion or exchange  rights,  as the case may
<PAGE>
be,  shall be deemed to have expired or  terminated  on the date when such price
change became effective in respect of shares not theretofore  issued pursuant to
the exercise or conversion or exchange thereof,  and the Company shall be deemed
to have issued upon such date new options,  rights or warrants or convertible or
exchangeable  securities  at the new price in  respect  of the  number of shares
issuable upon the exercise of such options, rights or warrants or the conversion
or exchange of such convertible or exchangeable securities.

         7.3 Subdivision and Combination.  In case the Company shall at any time
subdivide or combine the outstanding  shares of Common Stock, the Exercise Price
shall  forthwith  be  proportionately  decreased in the case of  subdivision  or
increased in the case of combination.

         7.4  Adjustment  in  Number of  Shares.  Upon  each  adjustment  of the
Exercise  Price  pursuant  to the  provisions  of this  Article 7, the number of
Shares  issuable  upon the  exercise  of each  Warrant  shall be adjusted to the
nearest full Share by multiplying a number equal to the Exercise Price in effect
immediately  prior to such  adjustment  by the  number of Shares  issuable  upon
exercise of the Warrants  immediately  prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

         7.5  Reclassification,  Consolidation,  Merger,  etc.  In  case  of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value,  or from no par value to par value, or as
a result of a subdivision or combination),  or in the case of any  consolidation
of the Company with, or merger of the Company into,  another  corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any  reclassification  or change of the outstanding
shares  of  Common  Stock,  except a  change  as a result  of a  subdivision  or
combination of such shares or a change in par value,  as  aforesaid),  or in the
case of a sale or  conveyance  to another  corporation  of the  property  of the
Company as an entirety,  the Holders shall thereafter have the right to purchase
the kind and  number  of  shares of stock  and  other  securities  and  property
receivable upon such reclassification,  change,  consolidation,  merger, sale or
conveyance  as if the  Holders  were the  owners of the  shares of Common  Stock
underlying the Warrants immediately prior to any such events at a price equal to
the product of (x) the number of shares  issuable  upon exercise of the Warrants
and (y) the Exercise  Price in effect  immediately  prior to the record date for
such reclassification,  change, consolidation,  merger, sale or conveyance as if
such Holders had exercised the Warrants.

         7.6    No Adjustment of Exercise Price in Certain Cases.  No adjustment
of the Exercise Price shall be made:

                  (a) Upon  the  issuance or sale of shares of Common Stock upon
         the exercise of the Warrants; or

                  (b) Upon (i) the issuance of options pursuant to the Company's
         employee stock option plan in effect on the date hereof or the issuance
         or sale by the  Company of any shares of Common  Stock  pursuant to the
         exercise  of any  such  options,  or (ii) the  issuance  or sale by the
         Company of any shares of Common  Stock  pursuant to the exercise of any
         options  or  warrants  previously  issued and  outstanding  on the date
         hereof; or

                  (c)    Upon the issuance of shares of Common Stock pursuant to
         contractual obligations existing on the date hereof; or

                  (d) If the  amount  of said  adjustment  shall be less  than 2
         cents  (2(cent)) per Share,  provided,  however,  that in such case any
         adjustment  that would  otherwise be required  then to be made shall be
         carried  forward and shall be made at the time of and together with the
         next  subsequent  adjustment  which,  together  with any  adjustment so
         carried forward, shall amount to at least 2 cents (2(cent)) per Share.

         7.7  Dividends  and Other  Distributions  with  Respect to  Outstanding
Securities.  In the  event  that the  Company  shall  at any  time  prior to the
exercise of all Warrants  declare a dividend  (other than a dividend  consisting
solely of shares of Common Stock or a cash dividend or distribution  payable out
of current or retained earnings) or otherwise distribute to its shareholders any
monies, assets, property,  rights, evidences of indebtedness,  securities (other
than shares of Common Stock), whether issued by the Company or by another person
or entity, or any other thing of value, the Holder or Holders of the unexercised
Warrants shall thereafter be entitled, in addition to the shares of Common Stock
or other securities  receivable upon the exercise thereof, to receive,  upon the
exercise of such Warrants, the same monies, property,  assets, rights, evidences
of  indebtedness,  securities  or any other  thing of value that they would have
been  entitled to receive at the time of such dividend or  distribution.  At the
time of any such dividend or  distribution,  the Company shall make  appropriate
reserves to ensure the timely  performance of the provisions of this  Subsection
7.7.
<PAGE>
         7.8 Subscription Rights for Shares of Common Stock or Other Securities.
In the case the Company or an affiliate  of the Company  shall at any time after
the date hereof and prior to the exercise of all the  Warrants  issue any rights
to subscribe  for shares of Common Stock or any other  securities of the Company
or of such affiliate to all the shareholders of the Company,  the Holders of the
unexercised  Warrants  shall be  entitled,  in  addition to the shares of Common
Stock or other  securities  receivable  upon the  exercise of the  Warrants,  to
receive  such  rights  at the time  such  rights  are  distributed  to the other
shareholders of the Company.

8.       Exchange and Replacement of Warrant Certificates.

         Each Warrant  Certificate is  exchangeable  without  expense,  upon the
surrender hereof by the registered  Holder at the principal  executive office of
the Company,  for a new Warrant  Certificate of like tenor and date representing
in the  aggregate  the  right to  purchase  the same  number  of  Shares in such
denominations  as shall be designated by the Holder  thereof at the time of such
surrender.

         Upon receipt by the Company of evidence  reasonably  satisfactory to it
of the loss, theft,  destruction or mutilation of any Warrant Certificate,  and,
in case of loss,  theft or  destruction,  of  indemnity  or security  reasonably
satisfactory to it, and reimbursement to the Company of all reasonable  expenses
incidental  thereto,  and upon surrender and  cancellation  of the Warrants,  if
mutilated,  the Company will make and deliver a new Warrant  Certificate of like
tenor, in lieu thereof.

9.   Elimination of Fractional Interests.

         The Company  shall not be required to issue  certificates  representing
fractions  of shares of Common Stock and shall not be required to issue scrip or
pay cash in lieu of  fractional  interests,  it being the intent of the  parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock.

10.      Reservation and Listing of Securities.

         The Company  shall at all times  reserve and keep  available out of its
authorized  shares of Common Stock,  solely for the purpose of issuance upon the
exercise  of the  Warrants,  such  number of shares of Common  Stock as shall be
issuable upon the exercise thereof.  The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor,  all shares
of Common Stock  issuable upon such exercise  shall be duly and validly  issued,
fully  paid,  nonassessable  and not  subject  to the  preemptive  rights of any
shareholder. As long as the Warrants shall be outstanding, the Company shall use
its best efforts to cause all shares of Common Stock  issuable upon the exercise
of the Warrants to be listed on or quoted on the electronic  bulletin  board, by
NASDAQ or listed on such  national  securities  exchanges  as  requested  by the
Placement Agent.

11.      Notices to Warrant Holders.

         Nothing  contained in this  Agreement  shall be construed as conferring
upon the Holder or Holders the right to vote or to consent or to receive  notice
as a shareholder in respect of any meetings of shareholders  for the election of
directors  or  any  other  matter,  or as  having  any  rights  whatsoever  as a
shareholder of the Company.  If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

         (a) the  Company  shall  take a record of the  holders of its shares of
Common  Stock  for the  purpose  of  entitling  them to  receive a  dividend  or
distribution  payable otherwise than in cash, or a cash dividend or distribution
payable otherwise than out of current or retained earnings,  as indicated by the
accounting  treatment  of such  dividend  or  distribution  on the  books of the
Company; or

         (b)      the Company shall offer to all the holders of its Common Stock
any additional shares of capital stock of the Company or securities  convertible
into or exchangeable for shares of capital stock of the Company,  or any option,
right or warrant to subscribe therefor; or

         (c) a dissolution, liquidation or winding up of the Company (other than
in connection with a consolidation  or merger) or a sale of all or substantially
all of its property, assets and business as an entirety shall be proposed;

then, in any one or more of said events,  the Company shall give written  notice
of such  event at least  fifteen  (15) days  prior to the date fixed as a record
date or the date of closing  the  transfer  books for the  determination  of the
shareholders   entitled  to  such   dividend,   distribution,   convertible   or
exchangeable securities or subscription rights, options or warrants, or entitled
to vote on such  proposed  dissolution,  liquidation,  winding up or sale.  Such
notice shall specify such record date or the date of closing the transfer books,
<PAGE>
as the case may be.  Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection  with the  declaration  or
payment of any such dividend or distribution, or the issuance of any convertible
or exchangeable  securities or subscription rights,  options or warrants, or any
proposed dissolution, liquidation, winding up or sale.

12.      Notices.

         All  notices,  requests,  consents and other  communications  hereunder
shall be in writing  and shall be deemed to have been duly made when  delivered,
or mailed by registered or certified mail, return receipt requested:

         (a)   If to a registered Holder of the Warrants, to the address of such
Holder as shown on the books of the Company; or

         (b) If to the  Company,  to the  address set forth in Section 3 of this
Agreement or to such other address as the Company may designate by notice to the
Holders.

13.      Supplements and Amendments.

         The Company and the Placement Agent may from time to time supplement or
amend this Agreement without the approval of any Holders of Warrant Certificates
in order to cure any ambiguity, to correct or supplement any provision contained
herein which may be defective or inconsistent with any provisions  herein, or to
make any other  provisions in regard to matters or questions  arising  hereunder
which the Company and the  Placement  Agent may deem  necessary or desirable and
which the  Company  and the  Placement  Agent deem not to  adversely  affect the
interests of the Holders of Warrant Certificates.

14.      Successors.

         All  the  covenants  and  provisions  of this  Agreement  by or for the
benefit of the Company and the Holders inure to the benefit of their  respective
successors and assigns hereunder.

15.      Termination.

         This  Agreement  shall  terminate at the close of business on August 4,
2003.  Notwithstanding  the  foregoing,  this  Agreement  will  terminate on any
earlier date when all Warrants have been  exercised and all the Shares  issuable
upon exercise of the Warrants have been resold to the public; provided, however,
that the provisions of Article 6 shall survive such termination  until the close
of business on August 4, 2003.

16.      Governing Law.

         Nothing in this  Agreement  shall be construed to give to any person or

any legal or equitable  right,  remedy or claim under this  Agreement;  and this
Agreement  shall be for the sole and  exclusive  benefit of the  Company and the

                               WARRANT CERTIFICATE

         This Warrant  Certificate  certifies that J.P. Carey  Securities,  Inc.
("J.P.   Carey")  or   registered   assigns,   is  the   registered   holder  of
____________Warrants to purchase, at any time from __________,  1998, until 5:00

         No Warrant may be exercised after 5:00 P.M.,  Eastern Standard Time, on
the  Expiration  Date,  at which  time all  Warrants  evidenced  hereby,  unless
exercised prior thereto, shall thereafter be void.

         The Warrants  evidenced by this Warrant  Certificate are part of a duly
authorized  issue of Warrants  issued pursuant to the Warrant  Agreement,  which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to in a description of the rights,  limitation

registered holder) of the Warrants.

evidencing  the  adjustment in the Exercise  Price and the number and/or type of
securities issuable upon the exercise of the Warrants;  pro vided, however, that
the failure of the Company to issue such new Warrant  Certificates  shall not in
any way change,  alter,  or  otherwise  impair,  the rights of the holder as set
forth in the Warrant Agreement.

         Upon due  presentment  for  registration  of transfer  of this  Warrant
Certificate at an office or agency of the Company, a new Warrant  Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants  shall be issued to the  transferees)  in exchange  for this Warrant
Certificate,  subject to the  limitations  provided  herein  and in the  Warrant

                               REGISTRATION RIGHTS

2.1      Securities Subject to this Agreement.

(a) The Securities entitled to the benefits of this Agreement are the Restricted
Securities, but only for so long as they remain Restricted Securities.

(b) A Person  is  deemed  to be a  holder  of  Restricted  Securities  (each,  a
"Holder")  whenever  such  Person is the  registered  holder of such  Restricted
Securities on the Company's books and records.

2.2      Shelf Registration.

(a)      The Company shall:

         (i) as expeditiously as practicable, but no later than 15 calendar days
from the Closing Date, amend its Shelf Registration  Statement on Form S-1 filed
with the Commission on January 8, 1998 pursuant to Rule 415 under the Securities
Act,  which  Shelf  Registration  Statement  shall  provide  for  resale  of all
Restricted  Securities  the Holders of which shall have  provided to the Company
the information required pursuant to Section 2.2(c) herein; and

         (ii) use its best efforts to cause such Shelf Registration Statement to
be  declared  effective  by the  Commission  as soon as  possible  but within 60
calendar days after the Closing Date.

         (iii)  if the  Company  is  advised  by  the  SEC  that a  Registration
Statement  filed  hereunder is subject to a  "no-review"  and such  Registration
Statement is not declared effective within ten (10) business days thereafter (an
"Acceleration  Date")  or,  irrespective  of  the  SEC  review,  a  Registration
Statement is not declared  effective by 60 calendar  days after the Closing Date
(the  "Target  Date"),  the Company  shall pay Holder as  liquidated  damages an
amount  equal to .0986% of the  total  principal  sum of the Notes for the first
thirty (30) day period following the earlier of the Acceleration  Date or Target
Date as  applicable  and  .1844%  per day  thereafter,  until  such  time as the
registration statement is declared effective.  The payment set forth above shall
be pro-rated  daily as to any period of less than thirty (30) days. Such payment
shall be made to the Holder by cashier's  check or wire transfer in  immediately
available funds to such account as shall be designated in writing by the Holder.
The
                                        4
<PAGE>
foregoing  amount  shall  be  paid  irrespective  of the  amount  of  Restricted
Securities then held by Holder.

         (iv)  if,  following  effectiveness  of  a  registration,   either  the
effectiveness of the registration statement is suspended or a current Prospectus
meeting the  requirements  of Section 10 of the  Securities Act is not available
for  delivery  by the  Holder  for any reason  (either  referred  to herein as a
"suspension"),  the Company shall thereupon pay to Holder as liquidated  damages
an amount  equal to two  percent  (2%) of the total  principal  sum of the Notes
previously  purchased  by  Holder  for  each  thirty  (30)  day  period  of  the
suspension.  The payment set forth above shall be pro-rated  daily as to periods
of less than  thirty  (30)  days.  Such  payment  shall be made to the Holder by
cashier's check or wire transfer in immediately  available funds to such account
as shall be designated in writing by the Holder,  and shall be paid irrespective
of the  amount  of  Restricted  Securities  held by  Holder on or after the date
following the suspension.

         (v) any amount  payable  pursuant to the  foregoing  provisions of this
Subsection  (a) shall be  delivered  on or before the third (3rd)  business  day
following the end of the calendar month in which such payment obligation arose.

         (vi) Subsections (a)(iii) and (a)(iv) are in addition to the provisions
of Section 4.7 hereof.

(b) In  connection  with the Shelf  Registration  Statement,  the Company  shall
comply  with all the  provisions  of  Section  2.4  below and shall use its best
efforts  to  effect  such  registration  to  permit  the sale of the  Restricted
Securities  being  sold in  accordance  with the  intended  method or methods of
distribution  thereof (as indicated in the information  furnished to the Company
pursuant to Section 2.2.  (c)).  Subject to Section 2.2(d) the Company shall use
its  best  efforts  to  keep  such  Shelf  Registration  Statement  continuously
effective,  supplemented  and amended as required by the  provisions  of Section
2.2(d) to the extent  necessary  to ensure that it is  available  for resales of
Restricted  Securities  by the Holders of Restricted  Securities,  and to ensure
that it conforms with the requirements of this Agreement, the Securities Act and
the policies,  rules and regulations of the Commission as announced from time to
time,  for a period of twenty four (24)  months  from the  Closing  Date or such
longer  period as required by Section  2.2(d) or such  shorter  period that will
terminate when all the Securities  covered by the Shelf  Registration  Statement
have been sold pursuant to the Shelf  Registration  Statement or otherwise cease
to be Restricted Securities. Upon the occurrence of
                                        5
<PAGE>
any event that would cause any Shelf  Registration  Statement or the  Prospectus
contained therein (i) to contain a material misstatement or omission or (ii) not
to be effective  and usable for sale or resale of Restricted  Securities  during
the period  required  by this  Agreement,  the  Company  shall file  promptly an
appropriate  amendment  to such  Shelf  Registration  Statement  or the  related
Prospectus or any document  incorporated  therein by  reference,  in the case of
clause (i),  correcting any such  misstatement or omission,  and, in the case of
either  clause (i) or (ii),  use its best efforts to cause such  amendment to be
declared effective and such Registration Statement and the related Prospectus to
become usable for its intended purpose(s) as soon as practicable thereafter.

(c) No  Holder  of  Restricted  Securities  may  include  any of its  Restricted
Securities in the Shelf Registration Statement pursuant to this Agreement unless
and until such Holder  furnishes  to the Company in writing,  within 10 Business
Days after receipt of a written request therefor,  such information specified in
Item 507 of Regulation S-K under the Securities Act or such other information as
the  Company  may  reasonably  request  for use in  connection  with  the  Shelf
Registration  Statement or Prospectus or preliminary Prospectus included therein
and in  any  application  to  the  NASD.  Each  Holder  as to  which  the  Shelf
Registration  Statement  is being  effected  agrees to furnish  promptly  to the
Company  all  information  required  to  be  disclosed  in  order  to  make  the
information  previously  furnished to the Company by such Holder not  materially
misleading.

(d) Notwithstanding  anything to the contrary contained herein, if (x) the Board
determines in good faith that the  registration  and  distribution of Restricted
Securities  (or the use of such Shelf  Registration  Statement or the Prospectus
contained  therein)  would  interfere  with any  proposed  or  pending  material
corporate  transaction involving the Company or any of its subsidiaries or would
require  premature  disclosure  thereof or would require the Company to disclose
information  that the Company has not otherwise made public and that the Company
reasonably determines is in the best interests of the Company not to disclose at
such time,  and (y) the Company  notifies  the Holders in writing not later than
three (3) days following such determination  (such notice a "Blackout  Notice"),
the Company may (A) postpone the filing of such Shelf Registration  Statement or
(B) allow such Shelf  Registration  Statement to fail to be effective and usable
or elect that such Shelf  Registration  Statement not be usable for a reasonable
period of time,  but not in excess of 30 days (a "Blackout  Period");  provided,
however,  that the  aggregate  number of days  included in all Blackout  Periods
shall not exceed 90 during any
                                        6
<PAGE>
consecutive  12 months and shall not exceed 150 during the period  specified  in
Section 2.2(b);  and provided  further,  that such period referred to in Section
2.2(b) during which the Shelf Registration Statement is required to be effective
and usable  shall be extended by the  aggregate  number of days during which the
Shelf  Registration  Statement  was not  effective  or  usable  pursuant  to the
foregoing provisions.

(e) In the event the number of shares  available under a Registration  Statement
filed pursuant to this Agreement is insufficient to cover all of the Registrable
Securities,  the Company shall amend the Registration  Statement,  or file a new
Registration Statement (on the short form available therefor, if applicable), or
both, so as to cover all of the Registrable Securities, in each case, as soon as
practicable,  but in any event  within  fifteen  (15) days  after the  necessity
therefor  arises  (based  on the  market  price of the  Common  Stock  and other
relevant  factors on which the Company  reasonably  elects to rely). The Company
shall  use its best  reasonable  efforts  to cause  such  amendment  and/or  new
Registration  Statement to become effective as soon as practicable following the
filing thereof.  For purposes of the foregoing  provision,  the number of shares
available under a Registration  Statement shall be deemed "insufficient to cover
all of the  Registrable  Securities"  if at any time the  number of  Registrable
Securities  issued or issuable upon  conversion of the Notes is greater than the
quotient  determined  by  dividing  (i) the  number of  shares  of Common  Stock
available  for resale under such  Registration  Statement by (ii) 2.0;  provided
that in the  case of the  initial  registration  of the  Registrable  Securities
pursuant to Section  2(a),  the  Company  shall be required to register at least
__________________  shares  of Common  Stock for  resale.  For  purposes  of the
calculation  set  forth  in the  foregoing  sentence,  any  restrictions  on the
convertibility  of the Notes shall be  disregarded  and such  calculation  shall
assume that the Notes are then  convertible  into shares of Common  Stock at the
then prevailing Conversion Price (as defined in the Notes).

2.3      Piggyback Registration.

(a) At any  time  that  the  Company  proposes  to file a  Company  Registration
Statement,  either for its own  account or for the account of a  stockholder  or
stockholders, the Company shall give the Holders written notice of its intention
to do so and of the intended method of sale (the "Registration Notice") within a
reasonable time prior to the anticipated filing date of the Company Registration
Statement effecting such Company Registration. Each holder may request inclusion
                                        7
<PAGE>
of any Restricted  Securities in such Company  Registration by delivering to the
Company, within ten (10) Business Days after receipt of the Registration Notice,
a written  notice (the  "Piggyback  Notice")  stating  the number of  Restricted
Securities  proposed to be  included  and that such shares are to be included in
any  underwriting  only on the same terms and conditions as the shares of Common
Stock otherwise being sold through  underwriters under such Company Registration
Statement.  The  Company  shall use its best  efforts  to cause  all  Restricted
Securities  specified  in the  Piggyback  Notice to be  included  in the Company
Registration  Statement and any related offering, all to the extent requisite to
permit the sale by the Holders of such Restricted  Securities in accordance with
the method of sale  applicable  to the other shares of Common Stock  included in
such Company  Registration  Statement;  provided  however,  that if, at any time
after giving  written  notice of its  intention to register any  securities  and
prior to the  effective  date of the  Company  Registration  Statement  filed in
connection  with such  registration,  the Company shall determine for any reason
not to register or to delay registration of such securities, the Company may, at
its  election,  give  written  notice of such  determination  of each  Holder of
Restricted Securities and, thereupon:

         (i) in the ease of determination not to register,  shall be relieved of
its  obligation to register any  Restricted  Securities in connection  with such
registration, and

         (ii) in the case of a delay in registering, shall be permitted to delay
registering  any  Restricted  Securities  for the same  period  as the  delay in
registering such other securities.

(b) The  Company's  obligation  to include  Restricted  Securities  in a Company
Registration  Statement  pursuant  to  Section  2.3(a)  shall be  subject to the
following limitations:

         (i) The Company may elect,  at its sole option and for any reason,  not
to register Holder's Restricted Securities; provided however, that this right is
limited to one (1) time and relative to one (1) particular Company  Registration
Statement.

         (ii) The  Company  shall not be  obligated  to include  any  Restricted
Securities in a registration statement filed on Form S-4, Form S-8 or such other
similar successor forms then in effect under the Securities Act.

         (iii)  If  a  Company  Registration  Statement involves an underwritten
offering and the managing underwriter advises the Company
                                        8
<PAGE>
in  writing  that in its  opinion,  the  number of  securities  requested  to be
included in such Company Registration  Statement exceeds the number which can be
sold in such offering without adversely affecting the offering, the Company will
include in such Company  Registration  Statement  the number of such  Securities
which the Company is so advised can be sold in such offering  without  adversely
affecting the offering, determined as follows:

                  (A) first,  the  securities proposed by the Company to be sold
for it own account, and

                  (B) second, any Restricted Securities requested to be included
in such  registration and any other securities of the Company in accordance with
the  priorities,  if and then existing among the holders of such  securities pro
rata among the holders thereof  requesting such registration on the basis of the
number of shares of such securities requested to be included by such holders.

         (iii)  The  Company  shall  not  be  obligated  to  include  Restricted
Securities in more than two (2) Company Registration Statement(s).

(c) No  Holder  of  Restricted  Securities  may  include  any of its  Restricted
Securities  in the Company  Registration  Statement  pursuant to this  Agreement
unless and until such Holder  furnishes  to the  Company in  writing,  within 10
business  days after receipt of a written  request  therefor,  such  information
specified in Item 507 of Regulation  S-K under the  Securities Act or such other
information as the Company may reasonably request for use in connection with the

(h) use its best efforts to cause the  disposition of the Restricted  Securities
covered by any Registration  Statement to be registered with or approved by such
other U.S.  governmental  agencies or  authorities as may be necessary to enable

occurred,  prepare a supplement or post-effective  amendment to any Registration
Statement  or  related  Prospectus  or  any  document  incorporated  therein  by

fiscal quarter in which  Restricted  Securities are sold to the underwriter in a
firm or best efforts underwritten offering or (ii) if not sold to an underwriter

Each Holder agrees by acquisition of a Restricted Security that, upon receipt of
any notice from the Company of the  existence of any fact of the kind  described
in Section 2.4(c)(iv),  or the commencement of the Black Out Period, such Holder
will forthwith discontinue  disposition of Restricted Securities pursuant to any
Registration  Statement  until  such  Holder's  receipt  of  the  copies  of the
supplemented  or  amended  Prospectus,  or until it is advised  in  writing,  in
accordance with the notice  provisions of Section 5.3 herein (the "Advice"),  by
the Company  that the use of the  Prospectus  may be resumed,  and has  received

offering or sale of such securities,

         (iii) each person,  if any, who controls (within the meaning of Section
15 of the  Securities  Act or Section 20 of the Exchange Act) any such Holder or
underwriter  (any  of  the  persons  referred  to in  this  clause  (iii)  being
hereinafter referred to as a ("controlling person") and

         (iv)  the  respective   officers,   directors,   partners,   employees,
representatives  and agents of any such Holder or underwriter or any controlling
person  (any  person  referred  to in  clause  (i),  (ii),  (iii)  or  (iv)  may

to the fullest  extent  lawful  from and  against  any and all  losses,  claims,
damages,  liabilities,  judgments or  expenses,  joint or several (or actions or
proceedings, whether commenced or threatened, in respect thereof) (collectively,
"Claims"),  to which such  indemnified  Person may become  subject  under either
Section 15 of the Securities Act or Section 20 of the Exchange Act or otherwise,
insofar  as such  Claims  wise out of or are based  upon,  or are  caused by any
untrue statement or alleged untrue statement of a material fact contained in any
Registration  Statement or Prospectus (or any amendment or supplement  thereto),
or any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, or
a violation by the Company of the Securities Act or any state securities law, or
any  rule or  regulation  promulgated  under  the  Securities  Act or any  state
securities law, or any other law applicable to the Company  relating to any such
registration or qualification,  except insofar as such losses, claims,  damages,
liabilities,  judgments  or expenses  of any such  indemnified  Person;  (x) are
caused by any such untrue  statement or omission or alleged untrue  statement or
omission  that is based upon  information  relating to such  indemnified  Person
furnished  in writing to the Company by or on behalf of any of such  indemnified
Person  expressly  for  use  therein;   (y)  with  respect  to  the  preliminary
Prospectus, result from the fact that such Holder sold Securities to a person to
whom there was not sent or given,  at or prior to the  written  confirmation  of
such sale, a copy of the Prospectus, as amended or
                                       17
<PAGE>
supplemented,  if the Company shall have previously  furnished  copies hereof to
such Holder in accordance with this Agreement and said Prospectus, as amended or
supplemented,  would have corrected such untrue statement or omission; or (z) as
a result  of the use by an  indemnified  Person  of any  Prospectus  when,  upon
receipt of a Black Out Notice or a notice from the Company of the  existence  of
any fact of the kind described in Section 2.4(b)(iv),  the indemnified Person or
the related  Holder was not permitted to do so. Such  indemnity  shall remain in
full force and effect  regardless of any  investigation  made by or on behalf of
any indemnified Person and shall survive the transfer of such securities by such
Holder.

In case any action shall be brought or asserted  against any of the  indemnified
Persons with respect to which indemnity may be sought against the Company,  such
indemnified  Person  shall  promptly  notify the Company  and the Company  shall
assume the  defense  thereof  Such  indemnified  Person  shall have the night to
employ  separate  counsel in any such action and to  participate  in the defense
thereof,  but the fees and expenses of such  counsel  shall be at the expense of
the indemnified Person unless (i) the employment of such counsel shall have been
specifically  authorized in writing by the Company,  (ii) the Company shall have
failed to assume the  defense and employ  counsel or (iii) the named  parties to
any such action  (including any implied  parties)  include both the  indemnified
Person and the Company and the  indemnified  Person  shall-have  been advised in
writing by its counsel that there may be one or more legal defenses available to
it which are different from or additional to those  available to the Company (in
which case the  Company  shall not have the right to assume the  defense of such
action on behalf of the indemnified Person), it being understood,  however, that
the  Company  shall not,  in  connection  with such action or similar or related
actions  or  proceedings   arising  out  of  the  same  general  allegations  or
circumstances,  be liable for the reasonable  fees and expenses of more than one
separate  firm of attorneys  (in addition to any local  counsel) at any time for
all  the  indemnified  Persons,  which  firm  shall  be (x)  designated  by such
indemnified Persons and (y) reasonably  satisfactory to the Company. The Company
shall not be liable for any settlement of any such action or proceeding effected
without the Company's prior written consent, which consent shall not be withheld
unreasonably,  and the  Company  agrees  to  indemnify  and  hold  harmless  any
indemnified Person from and against any loss, claim, damage, liability, judgment
or expense by reason of any  settlement of any action  effected with the written
consent of the Company. The Company shall not, without the prior written consent
of each  indemnified  Person,  settle or  compromise  or consent to the entry of
judgment on or otherwise seek to terminate any
                                       18
<PAGE>
pending or threatened action claim, litigation or proceeding in respect of which
indemnification  or  contribution  may be sought  hereunder  (whether or not any
indemnified  Person is a party  thereto),  unless such  settlement,  compromise,
consent or termination  includes an  unconditional  release of each  indemnified
Person  from all  liability  arising out of such  action,  claim  litigation  or
proceeding.

(b) Each Holder of Restricted  Securities covered by any Registration  Statement
agrees,  severally  and not jointly,  to indemnify and hold harmless the Company
and its directors,  officers and any person  controlling  (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company,
and the respective officers, directors, partners, employees, representatives and
agents of each person,  to the same extent as the foregoing  indemnity  from the
Company to each of the indemnified Persons, but only (i) with respect to actions
based on  information  relating  to such  Holder  furnished  in writing by or on
behalf  of such  Holder  expressly  for  use in any  Registration  Statement  or
Prospectus,  and (ii) to the extent of the gross proceeds,  if any,  received by
such  Purchaser  from  the sale or other  disposition  of his or its  Restricted
Securities  covered  by such  Registration  Statement.  In case  any  action  or
proceeding  shall be brought against the Company or its directors or officers or
any such controlling  person in respect of which indemnity may be sought against
a Holder of Restricted  Securities covered by any Registration  Statement,  such
Holder  shall have the rights and  duties  given the  Company in Section  2.8(a)
(except  that the Holder  may but shall not be  required  to assume the  defense
thereof),  and the Company or its  directors  or  officers  or such  controlling
person shall have the rights and duties given to each Holder by Section 2.8(a).

(c) If the indemnification provided for in this Section 2.8 is unavailable to an
indemnified  party  under  Section  2.7(a)  or (b)  (other  than  by  reason  of
exceptions  provided  in those  Sections)  in  respect  of any  losses,  claims,
damages,  liabilities,  judgments  or expenses  referred  to therein,  then each
applicable  indemnifying  party (in the case of the  Holders  severally  and not
jointly),  in lieu of indemnifying such indemnified  party,  shall contribute to
the amount paid or payable by such indemnified party as a result of such losses,
claims damages, liabilities,  judgments of expenses (i) in such proportion as is
appropriate to reflect the relative  benefits received by the Company on the one
hand and the Holder on the other hand from sale of Restricted Securities or (ii)
if such  allocation  provided by clause (i) above is not permitted by applicable
law, in such
                                       19
<PAGE>
proportion as is appropriate to reflect not only the relative  benefits referred
to in clause  (i)  above but also the  relative  fault of the  Company  and such
Holder in connection  with the  statements or omissions  which  resulted in such
losses,  claims,  damages,  liabilities,  judgments or expenses,  as well as any
other relevant  equitable  considerations.  The relative fault of the Company on
the one hand and of such Holder on the other shall be  determined  by  reference
to,  among other  things,  whether the untrue or alleged  untrue  statement of a
material  fact or the  omission  or alleged  omission  to state a material  fact
relates to information supplied by the Company or by such Holder and the parties
relative intent, knowledge,  access to information and opportunity to correct or
prevent such  statement  or omission.  The amount paid to a party as a result of
the losses,  claims,  damages,  liabilities  judgments and expenses  referred to
above shall be deemed to include,  subject to the  limitations  set forth in the
second  paragraph  of  Section  2.8(a),  any  legal  or other  fees or  expenses
reasonably  incurred by such party in connection with investigating or defending
any action or claim.

The Company and each Holder of Restricted Securities covered by any Registration
Statement agree that it would not be just and equitable if contribution pursuant
to this  Section  2.8(c) were  determined  by pro rata  allocation  (even if the
Holders were  treated as one entity for such  purpose) or by any other method of
allocation  which  does not  take  into  account  the  equitable  considerations
referred  to  in  the  immediately  preceding  paragraph.   Notwithstanding  the
provisions of this Section 2.8(c) no Holder (and none of its related indemnified
Persons) shall be required to contribute, in the aggregate, any amount in excess
of the amount by which the dollar  amount of  proceeds  received  by such Holder
upon the sale of the  Restricted  Securities  exceeds  the amount of any damages
which such Holder has  otherwise  been  required to pay by reason of such untrue
statement  or  omission  or alleged  omission.  No person  guilty of  fraudulent
misrepresentations  (within the meaning of Section 11(f) of the Securities  Act)
shall be  entitled  to  contribution  from any person who was not guilty of such
fraudulent misrepresentation.

The indemnity and contribution  provisions  contained in this Section 2.8 are in
addition to any liability  which the  indemnifying  person may otherwise have to
the indemnified persons referred to above.

2.9      Participation in Underwritten Registrations.

provided,  however, that such investment bankers and managers must be reasonably
satisfactory  to the  Company  or the  Holders,  respectively.  Such  investment
bankers and managers are referred to herein as the "underwriters".

(Democratic Rep. of Sao and Principe Decree-Law Ner.: 27/98, on Establishment of
STPETRO,  S.A.,  Saotomean  National  Oil  Company;  First  Addendum to official
Journal  Ner.:5/98,  Published  on July .., 1998.  Entry into force:  on July..,

                       into force on July.... July, 1998.

Whereas the  exploration  and  exploitation of natural  resources,  namely,  the
hydrocarbons  reveal to be as a relevant  addition to the production of national
wealth  that is  needed to the  development  of the  Country,  as well as to the
establishment of welfare to the Saotomean citizen;

Whereas  the  establishment  of  a  company  whose  business  activity  will  be
exploration and  exploitation  of hydrocarbons is the needful  condition to meet
this purpose,

Whereas,  moreover,  it is advisable the contribution  from the  internationally
experienced  foreign companies to assure technical and financial  co-partnership
to materialize this business activity, Now therefore,

The  Government of the  Democratic  Republic of Sao Tome and Principe  under the
article 99,  sub-paragraph  d) of the  Constitution  enacts and I promulgate  as
follows:

                                    Article 1

It is hereby approved the Statute of STPETRO, S.A. that is attached to
this diploma.
