                  ENVIRONMENTAL REMEDIATION HOLDING CORPORATION
                   Notes to Consolidated Financial Statements
                                   (Unaudited)


(1) Summary of Significant Accounting Policies
   Nature of operations.
          ERHC operates in the  environmental  remediation  industry and the oil
          and natural gas production industry from its corporate headquarters in
          Oyster  Bay,  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.

   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  the   consolidation.   The
          consolidated  financial  statements for the six months ended March 31,
          1998  and  1999  include  all  adjustments  which  in the  opinion  of
          management are necessary for fair presentation

   Cash equivalents
          The  Company  considers  all highly  liquid debt  instruments  with an
          original maturity of three months or less to be cash equivalents.

   Concentration of risks
          The  Company  primarily  transacts  its  business  with one  financial
          institution.

   Accounts receivable
          No allowance for uncollectible accounts has been provided.  Management
          has evaluated the accounts and believes they are all collectible.

   Compensation for services rendered for stock
          The  Company  issued  shares  of  common  stock  in lieu  of  services
          rendered.  The costs of the services are valued according to the terms
          of relative  agreements,  market value on the date of  obligation,  or
          based on the requirements of Form S-8, if applicable.  The cost of the
          services has been charged to operations.

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

(2) Going Concern
          The  Company's  current  liabilities  exceed  its  current  assets  by
          $7,719,705.  The Company has  incurred  net losses of  $3,129,872  and
          $4,520,958   in  the  six  months   ended  March  31,  1998  and  1999
          respectively.  These  conditions  raise  substantial  doubt  as to the
          ability of the Company to continue as a going concern.  The Company is
          in ongoing negotiations to raise general operating funds and funds for
          specific projects.  However, there is no assurance that such financing
          will be  obtained.  The  Company is in  preliminary  discussions  with
          several parties  regarding the potential sale of some to all of its US
          based crude oil  production  fields.  In prior years,  the Company was
          able to raise funds in a timely manner, there is no evidence that they
          will continue to do so in the future.

(3) Restricted Cash
          A total  balance of $18,826 in restricted  cash,  which is invested in
          interest-bearing  certificates of deposit, pledged as collateral for a
          performance bond covering the Utah properties.

(4) Property, Equipment, Depreciation and Depletion
          Property  and  equipment  are valued at cost.  Maintenance  and repair
          costs are  charged to expense as  incurred.  When items of property or
          equipment are sold or retired,  the related costs are removed from the
          accounts and any gains or losses are reflected as income. Depreciation
          is  computed  on the  straight-line  method  for  financial  reporting
          purposes, based on the estimated useful lives of the assets. Autos and
          trucks are depreciated over a three to five year life, field equipment
          over a five to fifteen  year life,  office  furniture  over a three to
          five year life, and the building over a thirty year life. Depreciation
          expense totaled $244,210, and $272,092 six months ended March 31, 1998
          and 1999,  respectively.  Depletion  (including  provisions for future
          abandonment and restoration  costs) of all capitalized costs of proved
          oil and gas producing properties is expensed using the unit-of-

(5) Notes payable
     The Company issued two notes payable to stockholders  who are also officers
     and  directors in exchange for cash  amounting to  $2,054,710.  These notes
     carry no stated maturity date and an 8.5% rate of interest. The Company has
     repaid $1,334,247 on these notes,  including interest and principal 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.

     In October 1998, the Company issued 20% convertible  subordinated unsecured
     notes due  October  2000 in exchange  for  $500,000  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 as of the issuance date  ($1.00),  the Company
     will be required to issue 500,000 shares of common stock.  These notes also
     carried warrants for an additional 1,500,000 shares of common stock with an
     exercise  price of $0.40 per share,  or total  additional  proceeds  to the
     Company of $600,000 in cash in the event all of the warrants are exercised.

     In October 1998, the Company issued 12% convertible  subordinated unsecured
     notes due December 31, 1999 in exchange for $800,000 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 ($1.25),  the Company will
     be  required  to issue  640,000  shares of common  stock.  These notes also
     carried "A" and "B"  warrants for an  additional  1,200,000  and  1,200,000
     shares of common stock with  exercise  prices of $0.50 and $3.00 per share,
     or total  additional  proceeds to the Company of  $4,200,000 in cash in the
     event all of the warrants are exercised.

     In October 1998, the Company received conversion notices on $412,350 of the
     convertible  debt issued in July and August,  1998.  This debt, and accrued
     interest amounting to $6,938, was converted into 1,210,686 shares of common
     stock.

(6) Accrued Salaries
     At March 31, 1998 and 1999 the Company has accrued  salaries of  $1,673,985
     and $2,252,575,  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.

(7) Accrued Interest
     Accrued interest consisted of the following at March 31 :

(9) Income Taxes
     The Company has a consolidated net operating loss  carry-forward  amounting
     to  $33,745,186,  expiring  as follows:  $3,404 in 2015,  $728,748 in 2016,
     $16,913,052  in 2017,  $11,582,428  in 2018  and  $4,520,958  in 2019.  The
     Company  has an  $13,498,000  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.  The Tax
     Reform Act of 1986  provided for a limitation  on the use of net  operating
     loss carryforwards  following certain ownership  changes.  Such a change in
     ownership  under the IRS  rules and  regulations  potentially  could  occur
     pursuant to the Company's S-1 amendment.

(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 stock.

     During the first  quarter of fiscal  1999,  the  Company  issued  1,059,000
     shares of common  stock in exchange for  services  valued at $523,687.  The
     Company also issued  200,000  shares in  settlement  of a then  outstanding
     accounts payable amounting to $142,000.  In October 1998,  convertible debt
     holders  converted  $412,350  of debt and $6,938 of accrued  interest  into
     1,210,686 shares of common stock.

    Rescinded and returned shares
     In  September  1998,  the Board of  Directors  authorized  the  issuance of
     100,000  shares to a director.  This  director  returned  the shares to the
     Company due to personal tax considerations. In September 1998, the Board of
     Directors authorized the issuance of 2,000,000 shares each to four officers
     and directors in connection with the DRSTP Agreement. In December 1998, the
     Board of Directors rescinded the issuance as if it had never occurred.

    Procura Financial Consultants, cc (PFC)
     Under the May 1997  Agreement  between the DRSTP and the Company,  PFC is a
     junior  partner to the  Agreement.  The Company and PFC are  negotiating an
     agreement whereby the Company would issue shares to PFC in exchange for PFC
     foregoing its rights under the May 1997 Agreement.  The Company has issued,
     but not  delivered  2,000,000  shares  in  anticipation  of  settling  this
     negotiation.  However,  at the date of this report no final  agreement  has
     been reached.

   Arbitration settlements
     The Company has notified  Kingsbridge  that it intends to cancel the equity
     line of credit previously negotiated. The negotiated cancellation agreement
     requires the Company to pay $100,000 in cash and issue warrants for 100,000
     shares of common stock.  This settlement  agreement has not yet been funded
     and Kingsbridge filed for arbitration in December 1998.

     In April 1998,  Uinta Oil and Gas, Inc. (Uinta) filed suit in Utah relating
     to the Company's  October 1997  acquisition of twenty two oil and gas wells
     in Utah.  The other two joint  sellers of these  wells,  along with  Uinta,
     filed a formal demand for arbitration as the purchase  agreement  requires.
     The Company has entered into negotiations to settle this matter and expects
     to issue additional shares in this settlement. However, at the date of this
     report, no final agreement has been reached.

(11) Commitments and Contingencies
     The Company is committed to lease payments for 10 vehicles under  operating
     leases  totaling  $50,598,  $7,826 and $3,913 for the years ended September
     30,  1999,  2000 and 2001.  The Company paid $19,160 and $12,650 in vehicle
     lease  expense  for the three  months  ended  December  31,  1997 and 1998,
     respectively.  The Company  currently leases its office space and operating
     facilities  on a two year  lease and three  year  lease  respectively.  The
     Company is  committed  to lease  payments on the two  facilities  totalling
     $67,108 and $60,808 for the years ending  September 30, 1999 and 2000.  The
     Company paid $11,487 and $17,227 in facility  rent for the six months ended
     March 31, 1998 and 1999, respectively.

(12) 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  in the
     environmental  remediation  industry  and BAPCO will operate in the oil and
     gas production  industry.  SSI's principal  identifiable  assets consist of
     $3,224,000,  net, of  environmental  equipment,  and the Chevron P&A master
     service  agreement  valued at $300,  net.  BAPCO's  principal  identifiable
     assets consist of crude oil reserves valued at $1,240,175, equipment valued
     at  $2,508,000  and land and building  valued at $98,782.  The Company also
     expects to operate in the supply industry through a joint venture agreement
     to supply fuel and other goods to ships  transiting  the Panama  Canal.  No
     principal identifiable assets yet exist for this line of business.

(13) Sao Tome Concession
    Concession fee 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.  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.

    Investment in STPetro, S.A.
     In July 1998,  the  Government of the  Democratic  Republic of Sao Tome and
     Principe established  STPetro,  S.A. as the national petroleum company. The
     charter  established the initial  ownership of STPetro,  S.A. as 51% by the
     government   and  49%  by  ERHC  in   exchange   for  $51,000  and  $49,000
     respectively.  The Company immediately  forwarded $20,000 of its $49,000 in
     cash,  and  believes  that  $29,000  of  expenses  it has paid on behalf of
     STPetro, S.A. prior to its formation will be credited to it for the balance
     owed.

   Due from STPetro,S.A.
     The Company has expended approximately $912,154 on behalf of STPetro, S.A.,
     principally  prior to the formation of STPetro,  S.A. The Company  believes
     that these expenses are recoverable  from STPetro,  S.A. under its May 1997
     agreement with the DRSTP.

(14) Suspended Revenue
     The Company's oil and gas production  revenue,  amounting to $156,282 as of
     March 31,  1999,  has been  placed in  suspense  as the Company has not yet
     received valid complete division orders on its leases and wells

(18) Subsequent Events
    Subsequent discovery
     Subsequent  to the filing of the  Company's  Form S-1  Amendment No. 3, and
     Form 10-K  Amendment  No. 1 for the year ended  September  30, 1998, it was
     discovered  that there may be a  question  of the  ownership  rights of the
     Company in the BAPCO  tool.The  Board of  Directors  was given notice under
     Section  10A(b)(2) of the  Securities and Exchange Act of 1934, as amended,
     and has filed a Form 8-K in  compliance  with the  requirements  of Section
     10A(b)(3).  The Company and its independent  auditors are conducting a full
     investigation. Upon completion of the investigation, the Company intends to
     amend its financial  statements  and other  disclosures,  should changes be
     warranted.  No changes have been made to the financial  statements  for the
     six months ended March 31, 1998 and 1999,  pending the  completion  of this
     investigation.

     Change of control,  resolution of subsequent discovery and going concern In
     April 1999, the Company  entered into a Letter of Intent to sell 51% of the
     Company to an investment group partially  composed of existing  convertible
     debt and warrant  holders in exchange for  $3,000,000.  $1,000,000  of this
     amount is to be forwarded directly to the DRSTP as the final installment of
     the original  concession  fee. At the time of entering  into this Letter of
     Intent,  the  Company's  Board  believe  that the  Company  faced  imminent
     involuntary  bankruptcy  proceedings,  as it had  been  made  aware of this
     probability.

     At  the  conclusion  of  the  auditor's  and  the  Company's  investigation
     regarding  the  potential  cloud on the title to the BAPCO tool,  the Board
     chose to realign its assets  between ERHC and its wholly owned  subsidiary,
     BAPCO. The original environmental equipment, the BAPCO tool and the Chevron
     contract were all placed in BAPCO, and all other BAPCO assets were moved to
     ERHC. The Board then spun-off  BAPCO to the former  President and Chairman,
     Sam Bass, via a recission of the original acquisition  transactions between
     ERHC and Sam Bass and entities  controlled by Sam Bass. In May, 1999,  ERHC
     has  received  the  7,744,000  shares  originally  issued to acquire  these
     assets.  No changes have been made to the financial  statements for the six
     months ended March 31, 1998 and 1999,  as the  transaction  occurred  after
     quarterend.

     The Company  filed an 8-K on May 21, 1999,  decribing all of the actions in
     detail.  The Company expects to file an 8-K amendment to include  pro-forma
     financial  statements as of September  30, 1998 and March 31, 1999,  giving
     effect to these  transactions  as if they had occurred at the  beginning of
     each period.

Item 2.  Management's  Discussion  and Analysis of the  Financial  Condition and
         Results of Operations

Overview

     The  Company  is  an  independent  oil  and  gas  company  engaged  in  the
exploration,  development,  production  and sale of crude  oil and  natural  gas
properties with current operations focused to a limited extent in Texas and Utah
and primarily in Sao Tome in West Africa.  The Company's goal is to maximize its
value through profitable growth in its oil and gas reserves and production.  The
Company has taken  steps to achieve  this goal  through  its growth  strategy of
managing  the   exploration,   exploitation  and  development  of  non-producing
properties  in known  oil-producing  areas,  such as the Gulf of  Guinea in West
Africa, with industry or government  partners.  The Company is in the process of
exploring the divestiture of certain of its oil and gas properties in the United
States, and seeking farm-out agreements for other of its properties.

     The Company  acquired  all of its oil and gas  properties  since 1997.  The
Company's current development plans require substantial capital  expenditures in
connection with the exploration, development and exploitation of oil and natural
gas  properties  in Sao  Tome.  The  Company  has  historically  funded  capital
expenditures  through a  combination  of  equity  contributions  and  short-term
financing arrangements.

     During the second  quarter 1999,  the Company was  attempting to secure its
position in Sao Tome, but had insufficient cash flow to meet certain commitments
of STPETRO. As a result of information acquired as a result of the annual audit,
it became  apparent that there was a cloud on certain of the  Company's  assets.
The Company filed a Form 8K so that it could investigate these issues;  however,
such  Form  8K  effectively   stopped  all  review  of  the  Company's   amended
Registration  Statement filed in January 1999. At the same time, the Company was
facing  increasing  penalties  and  interest  due to the  failure  to  have  its
Registration   Statement  declared   effective.   The  Board  of  Directors  was
considering  all  options  available  to  the  Company,   including  filing  for
protections under the Bankruptcy Act.

     In late  March,  the  Company  became  aware  of the  fact  that one of its
noteholders  was  interested  in  presenting  an offer to the Company to acquire
control. An initial offer was considered by the Board on April 1, 1999; however,
the Board felt that additional negotiations were required.

     On April 8, 1999, after  investigation and due consideration of the options
available to the Company  regarding  the cloud upon  certain of its assets,  the
Board  voted  to  realign  assets  between  itself  and its  subsidiary,  BAPCO.
Following such realignment,  all of the previous  transactions with Sam Bass and
his companies were  rescinded,  and BAPCO,  as realigned,  was  transferred to a
corporation,  unrelated  to  ERHC,  formed  for the  benefit  of Sam Bass or his
assigns.  This corporation would exchange the shares Mr. Bass and such companies
returned from the rescinded transactions, for all shares in the new corporation.
Such exchanged shares were to be returned to the Company for cancellation.

     On April 8, 1999, ERHC Investor Group Inc.  ("ERHCIG")  presented a revised
offer in the  form of a letter  of  intent  whereby  they  proposed  to  acquire
fifty-one percent (51%) of the issued and outstanding shares of the Company,  on
a fully diluted basis (the "Letter of Intent"). The Letter of Intent relied upon
certain  prior  actions  of the board  and final  closing  is  conditioned  upon
satisfactory  terms  and  conditions  in  the  form  of  a  Securities  Purchase
Agreement. The ERHCIG acquisition could be in one or more transactions and


<PAGE>



ERHCIG  was  permitted  to assign all or any part of its  rights.  The Letter of
Intent also provided for an Initial  Closing at which ERHCIG would subscribe for
the  requisite  percentage  of  shares,  subject  only to the terms of the Final
Closing. The Company executed the Letter of Intent on April 9, 1999.

     Pursuant to the Letter of Intent,  ERHC was  required to secure  Standstill
Agreements from its convertible note holders.  Each of the Standstill Agreements
was  specific  to  the  documents  for  such  investment.  However,  all  of the
Standstill  Agreements  contained at least the following:  (1) each contained as
Exhibit  A a copy of the  executed  Letter of Intent  and Term  Sheet;  (2) each
contained  a  provision   that  stated  that  the   information   provided   was
confidential,  non-public  information and required the investor to agree not to
disclose,  use or trade on such information directly or indirectly in any manner
until  the  filing  of the  Company's  Form  8-K;  (3)  all  adjustments  in the
Securities Purchase Agreement,  if applicable,  were deleted; (4) all conversion
prices were changed from that which was in the note to $.20 [thereby eliminating
the  conversion  formulas  which  were  in a  majority  of the  notes  requiring
conversion  at the  lesser  of  some  number  at  inception  or some  number  at
conversion]; (5) to the extent the adjustment provisions in the note varied from
the  note  adjustment  provisions  attached  as an  exhibit  to  the  Standstill
Agreements,  all  original  provisions  were  deleted and the  attached  exhibit
provisions   substituted  in  their  place  [thereby  eliminating   inconsistent
adjustment  provisions in the notes]; (6) to the extent antidilution  provisions
in the warrant varied from the warrant  antidilution  provisions  attached as an
exhibit to the Standstill  Agreement,  the original  provisions were deleted and
the attached exhibit provisions  substituted in their place [thereby eliminating
inconsistent  antidilution  provisions in the  warrants];  (7) to the extent the
note did not provide  for the  payment of interest in the form of Common  Stock,
such note was amended to provide  for the  payment of interest in Common  Stock;
(8) to the extent the note did not provide for the  conversion  of interest  and
penalties, if any, into Common Stock, at the time of a voluntary conversion of a
part or all of the  principal  sum of the note,  such  provision  was amended to
provide for the conversion of interest and penalties, if any, into Common Stock,
at the same time as the  conversion of a part or all of the principal sum of the
note;  (9) all  interest  on the note is  waived  from  the date of the  Initial
Closing until October 15, 1999 [thereby  allowing the Company to stay current on
its interest  payments];  (10) all penalties for failure to have a  registration
statement  declared  effective within a specified period of time are waived from
the date of the Initial  Closing until  October 15, 1999  [thereby  allowing the
Company to stay current on its penalty  payments];  (11) each  investor  agreed,
from the date of the Initial  Closing until October 15, 1999, not to convert all
or any part of their notes, not to declare a default or seek acceleration of any
payments under the notes; not to commence any foreclosure or bankruptcy  actions
under the note;  not to declare an event of default or commence any  arbitration
action under any of the  transaction  document;  (12) each  investor  waived all
rights in prior rights,  adjustments or antidilution  provisions relative to the
Letter of Intent and any settlement  with Procura  Financial  Consultants;  (13)
each investor  agreed to accept  shares of  restricted  Common Stock through the
Initial  Closing  date in lieu of  payments  in cash for all  accrued and unpaid
interest  and  penalties  on the notes at a  conversion  price of $.20  [thereby
allowing  the  Company to become  current  on all of its  interest  and  penalty
payments];  (14) each investor  agreed,  to the extent any third party commenced
any  bankruptcy  or  foreclosure  action,  to vote with the  Company;  (15) each
agreement  provided  that in the  event  no  Final  Closing  occurred,  that all
amendments,  modification  and consents  would be void ab initio;  and (16) each
investor  ratified the acts of the Board taken in  compliance  with the Business
Judgment Rule from inception through the Initial Closing.

     The  initial  closing  commenced  on  April  23,  1999;   however  not  all
documentation  was complete.  The last required document was the subscription of
the ERHCIG or its assigns. By document dated April 27, 1999 but delivered to the


<PAGE>



Company on May 14,  1999,  ERHC  Investor  Group LLC,  an  assignee,  executed a
Subscription  Agreement for twenty-one (21%) percent of fifty-one  percent (51%)
in consideration of the sum of $210,000; ERHC Investor Group A LLC, an assignee,
executed a  Subscription  Agreement  for 2.805% of  fifty-one  percent  (51%) in
consideration  of the  sum of  $165,000;  and  ERHC  Investor  Group  A LLC,  an
assignee,  executed a  Subscription  Agreement for 27.195% of fifty-one  percent
(51%) in consideration of the sum of $2,625,000.

     All of the Officers  resigned  effective  April 30, 1999. In addition,  Sam
Bass and Al Cotten  resigned from the Board effective April 23, 1999 and William
Beaton was removed  since he failed to  participate  in any actions of the Board
from prior to April 1, 199 through April 23, 1999 and was generally unavailable.
It was later  discovered  that Mr.  Beaton had been ill during  this  period and
unable to be  reached.  The  remaining  Board met on April 30, 1999 to elect (i)
three (3) replacement Directors, naming Ernest D. Chu, Stephen J. Warner and Lee
Hendelson; (ii) a new Chairman of the Board, naming Ernest D. Chu; and (iii) new
Officers  for the  Company,  naming  Stephen J.  Warner as  President  and Chief
Operating  Officer,  Ernest D. Chu as Treasurer and Chief Financial  Officer and
Lee Hendelson as Secretary. The Chairman, the New Directors and the New Officers
accepted and assumed their position effective the date of the meeting.  The four
(4) remaining Board members recused themselves when the New Directors voted upon
the Consulting  Agreements,  Severance Agreement and Settlement  Agreements with
such remaining members and former Officer, Directors,  Employees and Consultants
of the Company since such remaining  Board members clearly had a vested interest
in the outcome of such vote. Such members also recused  themselves while the New
Directors  voted  upon  certain  settlements  negotiated  with  various  parties
relative to  outstanding  claims and issues  involving  the Company,  since such
remaining Board members had not participated in these negotiations.

     As of May 14, 1999, control of the Company effectively changed,  subject to
the Final Closing.

     The  following   discussion   should  be  read  in  conjunction   with  the
Consolidated  Financial Statements and notes thereto appearing elsewhere in this
Form 10Q.

Results of Operations

     Second  Quarter Ended March 31, 1999 compared to Second Quarter Ended March
31, 1998.

     During the second quarter ended March 31, 1999, the Company  incurred a net
loss of  $1,681,429,  compared to a net loss of  $713,578 in the second  quarter
ended March 31,  1998,  reflecting  the  Company's  decreased  level of business
operations.  In the second quarter ended March 31, 1999, a total of $353,774 was
accrued, but not paid in cash, as compensation to three officers of the Company.
Depreciation  and depletion  equaled $ 74 in the second  quarter ended March 31,
1999 compared to $1,722 in the second quarter ended March 31, 1998. Amortization
of the beneficial  conversion  feature  discount on convertible debt was $89,417
for the quarter  ended March 31, 1999 compared to $646,517 for the quarter ended
March 31,  1998.  The net cash  operating  loss of the  Company  for the  second
quarter  ended March 31, 1999 was  $183,193  compared to $962,940 for the second
quarter ended March 31, 1998.

     Officers'  compensation,  professional  fees,  travel,  consultant fees and
miscellaneous  expenses  for the quarter  ended  March 31, 1999  compared to the
quarter ended March 31, 1998 increased significantly due to the Company's


<PAGE>



business  operations  continuing to increase.  Professional  fees in the quarter
ended March 31, 1999 included  legal,  audit,  petroleum  engineering  and other
engineering costs.

     The Company had revenues of $ 0 in the second  quarter ended March 31, 1999
compared to $259,830 in the second quarter ended March 31, 1998.

Liquidity and Capital Resources

     Historically,  the Company has financed its operations from the sale of its
debt  and  equity  securities  (including  the  issuance  of its  securities  in
consideration for services and/or products) and bank and other debt. The Company
had  expected to finance its  operations  and further  development  plans during
fiscal  1999 in part  through  additional  debt or  equity  capital  and in part
through cash flow from operations.  However,  due to the fact that the Company's
Registration  Statement had not been declared  effective,  the Company has found
additional debt and equity financing unavailable.  Under the terms of the Letter
of Intent, the Company secured Standstill  Agreements from its noteholders which
allowed  for the  Company  to  become  current  on all of its debt  obligations,
including  interest and penalties  through the date of the Initial Closing,  and
waived interest and penalties until October 15, 1999. The Company  believes that
this  standstill  period  places  it in the  position  to review  its  financial
structure  and put together a financial  plan which will allow the Company to go
forward with its operations.

     The Company  presently  intends to utilize any cash flow from operations as
follows:  (i) seismic studies and fees for the Sao Tome joint venture;  and (ii)
working capital and general corporate purposes.

Capital Expenditures and Business Plan

     In May 1997, the Company  entered into an exclusive  joint venture with the
Democratic  Republic  of  Sao  Tome  &  Principe  ("Sao  Tome")  to  manage  the
exploration,  exploitation and development of the potential oil and gas reserves
onshore and offshore Sao Tome,  either  through the venture or in  collaboration
with major  international oil exploration  companies.  At that time, the Company
was required to pay a $5,000,000  concession fee to the Sao Tome government.  In
September 1997, the Company received a Memorandum of Understanding  from the Sao
Tome government  which allows the Company to pay this concession fee within five
days after Sao Tome 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 Sao Tome from the net proceeds of the
1997 Private  Placement,  in June 1998,  paid  $1,000,000 of this concession fee
from the net proceeds of the Third June 1998 Private Placement,  in August, paid
$1,000,000 of this concession fee from the net proceeds of the July/August  1998
Financing.  $250,000  was  paid  from the net  proceeds  of the  September  1998
Financing  and  $500,000  was paid from the net  proceeds  of the  October  1998
Financing to pay other expenses and  obligations  relative to Sao Tome which the
Company believes will be credited to the concession fee.

     The Company is currently in the initial phase of project development and is
conducting  seismic  surveys,  processing  existing  seismic data and  reviewing
environmental  and  engineering  feasibility  studies.  During fiscal 1997,  the
Company  issued  1,000,000  shares of its common stock to acquire  geologic data
concerning Sao Tome. The Company anticipates spending  approximately  $2,200,000
over the next 12 months  for  additional  studies  necessary  to  determine  the
location and depth of the targeted oil  deposits.  The Company has spent to date
$250,000 in preparatory expenses including  determining the boundaries of the


<PAGE>



concession  and  facilitating  the  passage of a law in Sao Tome  regarding  the
boundaries  of the  country.  The costs of further  development  of this project
cannot be determined until a more definite development plan is established.  The
costs depend on the Company's  determination to either independently develop the
concession,  take on  operational  partners or lease a portion of the concession
for third-party development.

     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 were  expected to occur in early  1999.  In June 1998,  the
Company  and Sao  Tome  signed  a  letter  of  intent  to  award a  contract  to
Schlumberger  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  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 the  Government of Sao Tome.
The oil company is called the STPETRO. STPETRO is owned 51% by the Government of
Sao Tome and 49% by the Company. In addition,  the Company was granted under the
original agreement with the government,  a long term management arrangement with
STPETRO.  In July 1998, the Ministry of Cabinets and the Prime Minister executed
the  STPETRO  formation  documents  and they  were  promulgated  into law by the
President.  In September  1998, the  Government of Sao Tome and STPETRO  entered
into a Technical  Assistance  Agreement with Mobil. Under such agreement,  Mobil
will  perform  a  technical  evaluation  and  feasibility  study  of oil and gas
exploration in certain designated acreage.  The agreement is for an initial term
of 18 months  and  superceded  the need for  lease  sales in early  1999.  Mobil
retains  a right of first  refusal  to  acquire  development  rights to all or a
portion of the acreage which it is evaluating.  Mobil then executed an agreement
with  Schlumberger  to perform the marine  seismic  survey as previously  agreed
under the  letter of intent  with the  Company  signed in June  1998.  Under the
Mobil/Schlumberger agreement,  Schlumberger began performing seismic work on the
option  blocks  designated  in the TAA  Agreement in January  1999.  The Company
continues to maintain a right to construct the Off-Shore Logistics Center and is
seeking an appropriate joint venture partner for the project.

     Revenues from the Company's  operations in Sao Tome and  substantially  all
raw material purchases for use in Sao Tome will be U.S.  dollar-denominated  and
managed  through  the  Company's  Louisiana  operational  facility.  The Company
believes  that  it  will  not  be   significantly   affected  by  exchange  rate
fluctuations  in local  African  currencies  relative  to the U.S.  dollar.  The
Company believes that the effects of such  fluctuations will be limited to wages
for local  laborers and operating  supplies,  neither of which is expected to be
material to the Company's  results of operations  when the joint venture  begins
more substantial operations in Sao Tome.

     In October  1997,  the Company  acquired a 37.5%  interest in a 49,000 acre
natural gas lease,  known as the "Nueces  River  Prospect,"  in the Nueces River
area of south Texas.  The Company paid  $200,000 and issued 50,000 shares of its
common  stock to acquire the lease.  The  Company  has spent more than  $200,000
reworking  the  first of two  existing  shut-in  wells on the  property.  Due to
mechanical  failure  downhole,  this well has been shut in again.  In 1998,  the
Company   planned  on  spending   $650,000  to  $1,200,000  to  make  the  wells
operational,  utilizing funds to be acquired under the Investment Agreement with
Kingsbridge. The Company believes that, assuming the entire lease is productive,
there are about 75 locations to be drilled. In 1998, depending on the


<PAGE>



availability  of funding,  the  Company  expected to drill 15 to 20 new wells at
this site,  at a cost of  approximately  $650,000 to  $1,200,000  per well.  The
Company is  responsible  for only half of the drilling  cost of each well, as it
shares  this cost with its  operational  co-venturer,  Autry  Stephens & Co. The
operational  dates,  as well as the daily  production  rates, of the second well
cannot be  determined  until the  completion  of the  reentry.  The  Company  is
currently  meeting with two potential  farm-out partners to work the project and
believes  it will  negotiate  arrangements  to  drill  additional  wells  on the
northern and southern portions of the leasehold.

     In February  and March 1997,  the  Company  acquired  leases in oil fields,
which together comprise approximately 1,200 acres and 200 wells, located in Rusk
County and Wichita  County,  Texas.  The Company  issued  500,000  shares of its
common  stock to acquire  the leases.  Through  December  1997,  the Company had
recompleted  18 wells,  all of which were  operational  as of March 20, 1998. Of
these wells, 13 had mechanical failures.  The Company has located its BAPCO Tool
on  site.  The  Company  anticipates  spending  $1,200,000  in  order  to  bring
production  on the fields up to a commercial  level.  At the current  time,  the
Company is evaluating  feasible economic options including the potential sale of
the Rusk County and Wichita County properties.

     In  July  1997,  the  Company  entered  into  a  joint  venture  with  MIII
Corporation, a Native American oil and gas company, to workover,  recomplete and
operate 335  existing oil and gas wells on the Uintah and Ouray  Reservation  in
northeastern Utah. At this time, none of the wells are operational.  The Company
had designed a development  program,  under which it planned to  recomplete  and
restimulate 36 wells and to drill five to seven  development and extension wells
at this site.  This plan would  require  spending  a minimum  of  $1,000,000  to
$1,500,000 in order to make the project operational. Subject to the availability
of such funds, the Company  anticipated that the first wells would be on line by
fall 1998. The leases on the MIII project were never  transferred to the Company
and it is currently evaluating its options with regard to this project. Prior to
the Letter of Intent, the Company placed a stop transfer order on certain shares
issued to MIII relative to this project.

     In September 1997, the Company acquired net revenue  interests ranging from
76% to 84% (and 100% working  interest in all but 2 of the wells) in oil and gas
properties  totaling  13,680  acres,  located  near the MIII fields in the Uinta
Basin with 22 oil and natural gas wells.  These  wells are  currently  producing
approximately  70 barrels of oil per day from six  producing  wells  which began
realizing  revenues  for the Company in November  1997.  The Company  planned on
spending approximately  $1,000,000 on additional equipment and up to $80,000 per
well on well  stimulation  in order to bring 12 more wells on line in 1999.  The
Company  plans to plug and abandon 2 more wells and to perform  further study on
the other 2 wells.  The Company  planned on funding this plan through the use of
funds acquired under the Kingsbridge  Equity Line of Credit Agreement.  To date,
the Company has received no funds under the Kingsbridge Investment Agreement, no
longer intends to take down any funds under this agreement, has negotiated terms
to cancel this agreement and Kingsbridge is seeking arbitration of the agreement
and  its  cancellation.  The  Company  is  currently  evaluating  a sale of this
property.  The  Company  settled an  arbitration  brought by the Uintah  sellers
regarding this project and executed a settlement agreement in January 1999.

     In April 1997,  the Company  entered into a master  service  agreement with
Chevron to rework,  in order to draw additional  production from,  approximately
400 depleting  oil and gas wells and to remediate  and "plug and abandon"  these
and other wells when depleted, in Chevron's oil fields in southern Louisiana


<PAGE>



along the Gulf of Mexico.  The Chevron agreement  provided for a three-year work
schedule,  commencing  upon the  completion  of the Company's 140 foot "plug and
abandonment" barge. This barge was to be used to remediate offshore oil rigs and
be capable of working in coastal  waters as shallow as 19 inches.  A substantial
deposit was made by the Company to secure the barge.  The Company  believes  the
original  barge  supplier  will not be able to  deliver  since  the owner of the
company died. The Company is attempting to recover the deposit and is seeking an
alternate  supplier.  Due to the price  structure of the oil and gas business at
this time, the Company decided that it was not in its best interest to construct
this barge. The Chevron  agreement was originally  entered into by BAPCO and BEW
in September  1996,  prior to the  acquisition  of BAPCO by the Company in April
1997, and was assigned to the Company with Chevron's  consent at the time of the
acquisition.  The  Company  issued  3,000,000  shares of Common  Stock to BEW in
connection with the assignment of this agreement. Pursuant to the actions of the
Board on April 8, 1999,  this asset was  reassigned to BAPCO and  transferred to
the corporation  formed for the benefit of Mr. Bass as part of the rescission of
transactions involving Mr. Bass and his companies.

     During fiscal 1997, the Company issued 4,000,000 shares of its common stock
to acquire BAPCO, a non-operating  oil production  company with significant well
rework equipment assets.  Pursuant to the actions of the Board on April 8, 1999,
this asset was transferred to the corporation formed for the benefit of Mr. Bass
as part of the rescission of transactions involving Mr. Bass and his companies.

     The  Company's  current   development  plans  require  substantial  capital
expenditures in connection with the exploration, development and exploitation of
its oil and natural gas  properties in Sao Tome.  Historically,  the Company has
funded capital  expenditures  through a combination of equity  contributions and
short-term financing  arrangements.  The Company believes that it will require a
combination of additional  financing and cash flow from  operations to implement
future  development  plans. Under the terms of the Letter of Intent, the Company
will receive  $3,000,000  for the  acquisition  of 51% percent of its stock on a
fully diluted  basis.  New  management  is exploring  the private  and/or public
equity markets as potential  capital  sources in connection with its development
plans and  believes  that  certain  sources  with whom they have met may be in a
position  to  provide  the long term  financing  needed by the  Company to fully
exploit the  Company's  Sao Tome  projects.  There can be no assurance  that any
additional  financing  will be  available to it on  reasonable  terms or at all.
Future cash flows and the  availability of financing will be subject to a number
of variables, such as the level of production from existing wells, prices of oil
and natural  gas and success in locating  and  producing  new  reserves.  To the
extent that future financing  requirements are satisfied through the issuance of
equity  securities,  shareholders  of the Company may  experience  dilution that
could be  substantial.  The  incurrence  of debt  financing  could  result  in a
substantial  portion of  operating  cash flow being  dedicated to the payment of
principal  and  interest on such  indebtedness,  could  render the Company  more
vulnerable  to  competitive  pressures  and economic  downturns and could impose
restrictions on operations. If revenue were to decrease as a result of lower oil
and natural gas prices,  decreased production or otherwise,  and the Company had
no availability  under a bank arrangement or other credit facility,  the Company
could have a reduced  ability  to execute  current  development  plans,  replace
reserves  or to  maintain  production  levels,  any of  which  could  result  in
decreased production and revenue over time.

Reserves and Pricing

     Oil and natural gas prices fluctuate throughout the year. Generally, higher
natural gas prices  prevail  during the  winter  months of  September throug


<PAGE>



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. Such decline occurred in fiscal 1998. This was
primarily due to excess oil supplies worldwide.

     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  does not
intend to continue to acquire and develop oil and natural gas  properties in the
United States unless 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. 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  expects  to  utilize  the  "successful   efforts"  method  of
accounting  for its oil and gas  producing  activities  once it has  reached the
producing  stage.  The Company  expects to regularly  assess  proved oil and gas
reserves for possible  impairment on an aggregate  basis in accordance with SFAS
No. 121.

Net Operating Losses

     The Company has net  operating  loss  carryforwards  of  $33,745,186  which
expire in the years 2010 through 2019.  The Company has a  $13,498,000  deferred
tax asset resulting from the loss carryforwards,  for which it has established a
100%  valuation  allowance.  Until the  Company's  current  operations  begin to
produce earnings, it is unclear as to the ability of the Company to utilize such
carryforwards.

Year 2000 Compliance

     The Company is  currently  in the  process of  evaluating  its  information
technology for Year 2000  compliance.  The Company does not expect that the cost
to modify its information  technology  infrastructure  to be Year 2000 compliant
will be  material  to its  financial  condition  or results of  operations.  The
Company does not  anticipate  any material  disruption  in its  operations  as a
result of any failure by the Company to be in compliance.

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

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

           None
                           PART II - OTHER INFORMATION

Item 1.   Legal Proceedings

     Uinta Oil & Gas, Inc., ("Uinta") one of the three "joint" sellers under the
agreement  to acquire the Uinta  leases and certain  other  assets took  certain
actions that were in  contravention  of the agreement  when certain  anticipated
funding to the  Company  did not occur.  The  Company  gave Uinta  notice of its
demand for arbitration under the agreement. Uinta commenced an action agains the
Company, BAPCO, Sam L. Bass, Jr., Noreen Wilson, Jim Griffin, Robert E. McKnight
and Robert  Ballou (the  Company's  geologist) in Uintah  County,  Utah in April
1998.  The  complaint  alleges  fraud  in  the  inducement,  rescission  of  the
agreement, breach of contract and securities fraud and requests punitive damages
and  appointment  of a  receiver.  The  Company  then filed a formal  demand for
arbitration.  Uinta filed a request for a receiver to be appointed.  This motion
was denied; however, the court held the issue of arbitration in abeyance pending
an evidentiary  hearing on the allegations of Uinta's allegations of fraud since
Utah  law  contains  an  exception  to  mandatory  arbitration  when  there  are
allegations  of  fraud.  Prior to the  hearing  on  receivership,  the other two
"joint" sellers, Coconino, S.M.A., Inc. and Pine Valley Exploration,  Inc. filed
their formal demand for  arbitration.  The Company believed that it has numerous
meritorious  defenses to this action. In the interim,  the Company made an offer
to settle this matter. A settlement on all issues was completed in January 1999.
Under the terms of the executed settlement, for the 500,000 shares of restricted
stock  which  were  issued  at a  guarantee  price of $2 per  share,  additional
restricted  shares were issued which reflect the  difference  between $2 and the
price on October  16,  1998 and  December  30,  1998 and the  500,000  shares of
restricted  stock  which were to be issued in early 1998 were issued and treated
as if issued at the time such deliverance was initially  required.  In addition,
the parties will receive  additional shares equal to the difference  between the
value  calculated  on the closing  date in January  1999 and $2  (calculated  at
$.3267 per share,  the  "Strike  Price") for the second  block of  500,000.  The
Company  reimbursed  certain  filing fees,  attorneys  fees and paid for certain
office  equipment.  The Company  received a quitclaim  deed and  assignments  to
perfect the  Company's  interest in the leases.  In addition,  (1) Uinta will be
issued  shares  of the  Company's  Common  Stock the  amount  of which  shall be
determined by dividing  $250,000 by the Strike Price, half of which shares shall
be  included  in  the  Company's  registration  statement  on  Form  S-1/A  (the
"Registration Statement") and half of which shall be restricted securities,  (2)
in exchange for  assignment  of a 4%  overriding  royalty  interest,  Uinta will
receive  restricted  shares the amount of which shall be  determined by dividing
$677,000 by the Strike  Price,  (3) a deficiency  value equal to $41,200 for the
Utah office building will be liquidated by issuance of shares the amount of


<PAGE>



which shall be equal to $41,200  divided by the Strike Price,  which shares were
included in the Registration  Statement,  (4) Uinta receivedno more than $10,000
to cost its court  costs and  attorneys  fees,  and (5)  payment of  outstanding
production  service  invoices to third parties  totally $27,000 shall be paid in
the form of shares included in the Registration Statement, which shares shall be
equal to $27,000  divided by the Strike Price.  See Part II, Item 2. "Changes in
Securities and Use of Proceeds - January 1999 Shares Issuances."

     On August 11,  1998,  the Company and  Kingsbridge  agreed to enter into an
agreement to cancel the  Kingsbridge  Private  Equity Line of Credit dated March
23, 1998. Pursuant to the terms of the proposed  cancellation,  the Company will
pay a penalty in the amount of $100,000  and will issue  warrants to purchase up
to an additional  100,000 shares of the Company's Common Stock (the "Kingsbridge
Warrants").  The Company has decided to cancel the  Kingsbridge  Private  Equity
Line of Credit  because  terms of certain  of the third  quarter  1998  fundings
require the Company to cancel this agreement so as to limit the number of shares
of the  Company's  Common Stock  outstanding  upon  conversion  of the Company's
convertible notes in the future.  However,  as of December 31, 1998, the Company
had not  completed  the terms of the  anticipated  cancellation,  and  therefore
continues to be obligated to register the potential  Kingsbridge shares issuable
under the put option  exercise  notice and the  Kingsbridge  Warrant.  Under the
terms of the cancellation,  the Company will be responsible for the registration
of the additional warrants.  On December 10, 1998,  Kingsbridge made application
to the American  Arbitration  Association for arbitration of outstanding  issues
between the parties,  claiming  beaches of  contracts.  The Company has filed an
Answer in such  proceedings.  The Company  believes it has just and  meritorious
defenses to the claims and intends to vigorously defend these claims. An initial
arbitration conference is scheduled for mid May 1999.

     Other than the above  legal  proceeding,  the Company is not a party to any
other  material  pending or threatened  legal  proceeding  outside the course of
ordinary business.

Item 2.    Changes in Securities and Use of Proceeds

     There have been no changes  with  respect to defining the rights of holders
of any class of registered  securities or otherwise  other than those  described
above relative to the Standstill Agreements executed under the Letter of Intent.

     In the second fiscal  quarter 1999 and through the most  practicable  date,
the Company  issued the following  rights,  shares and warrants of  unregistered
securities:

January 1999 Share Issuances

     In January 1999, the Company agreed to a settlement with Uinta. Pursuant to
such  settlement,  the Company issued shares of Common Stock on January 18, 1999
and agreed to issue additional  shares based upon the Strike Price determined on
January 18, 1999. The  Registration  Statement  covers the up to 1,144,000 total
shares of Common Stock  issuable,  with  certainty,  upon the  completion of the
Uinta settlement.

     Under the  terms of the  executed  settlement,  for the  500,000  shares of
restricted  stock  which  were  issued  at a  guarantee  price of $2 per  share,
additional restricted shares were issued which reflect the difference between $2
and the price on October 16, 1998 and  December  30, 1998 (under the formula set
forth in the  agreement,  861,111  and  1,312,500  shares  of  restricted  stock
respectively) and the 500,000 shares of restricted stock which were to be issued
in early 1998 were issued and treated as if issued at the time such deliverance


<PAGE>



was initially  required,  which shares bear registration rights and are included
in the Registration  Statement. In addition, the parties will receive additional
shares equal to the difference between the value on the closing dated of January
18, 0999 and $2 for the second  block of 500,000  (2,560,912  at Strike Price of
restricted stock).  The Company  reimbursed certain filing fees,  attorneys fees
and paid for certain office equipment. The Company received a quitclaim deed and
assignments to perfect the Company's  interest in the leases.  In addition,  (1)
Uinta will be issued  shares of the  Company's  Common Stock the amount of which
was  determined by dividing  $250,000 by the Strike Price,  half of which shares
were included in the  Registration  Statement and half which shall be restricted
securities (at the Strike Price,  382,614 shares of restricted stock and 382,614
shares  which bear  registration  rights and are  included  in the  Registration
Statement) , (2) in exchange for assignment of a 4% overriding royalty interest,
Uinta will receive  restricted shares the amount of which shall be determined by
dividing  $677,000 by the Strike Price (2,072,238  shares of restricted  stock),
(3) a  deficiency  value equal to $41,200 for the Utah office  building  will be
liquidated  by  issuance of shares the amount of which shall be equal to $41,200
divided by the Strike Price,  (126,110 shares of Common Stock, which shares bear
registration  rights and are included in the Registration  Statement,  (4) Uinta
received no more than $10,000 to cost its court costs and  attorneys  fees,  and
(5) payment of outstanding  production service invoices to third parties totally
$27,000  shall be paid in the form of shares  with  registration  rights,  which
shares  shall be equal to $27,000  divided by the Strike  Price  (82,644  shares
which are included in the Registration Statement).

     In July  1997,  the  Company  acquired  certain  geological  data and other
information  relative to Sao Tome valued at $2,000,000 from Christian Hellinger.
At that time,  the  Company  issued  1,000,000  shares of its Common  Stock at a
guaranteed  price of $2.00 per share.  Subsequently,  the price of the Company's
shares  dropped.  Through  December 31, 1998, the Company had repaid $908,925 of
the  $2,000,000  debt.  In  January  1999,  the  Board of  Directors  reached  a
settlement with Mr. Hellinger  relative to the balance of $1,091,075 in which he
agreed to take 3,308,712 share of restricted Common Stock in full liquidation of
the balance due.

February and March 1999 Share Issuances

     Pursuant to an agreement  with the holder of the Third June 1998 Note,  the
Company  has  agreed  to  issue  512,501  shares  of  Common  Stock  which  have
registration  rights and which have been included in the Registration  Statement
in lieu of certain  penalties  associated with the Company's failure to have its
Registration  Statement  effective  within  sixty  days.  See Part  II,  Item 3.
"Defaults Upon Senior Securities."

April 1999 Letter of Intent

     On April 8, 1999, after  investigation and due consideration of the options
available to the Company  regarding  the cloud upon  certain of its assets,  the
Board  voted  to  realign  assets  between  itself  and its  subsidiary,  BAPCO.
Following such realignment,  all of the previous  transactions with Sam Bass and
his companies were  rescinded,  and BAPCO,  as realigned,  was  transferred to a
corporation,  unrelated  to  ERHC,  formed  for the  benefit  of Sam Bass or his
assigns.  This corporation would exchange the shares Mr. Bass and such companies
returned from the rescinded transactions, for all shares in the new corporation.
Such exchanged shares were to be returned to the Company for cancellation.  They
included the 4,000,000 shares issued to Mr. Bass in the BAPCO  acquisition,  the
744,000  shares  issued  to Mr.  Bass's  company,  for  the  acquisition  of the
environmental remediation equipment and the 3,000,000 shares issued to


<PAGE>



Mr.  Bass's company for the Chevron Master Service Agreement.

     At the meeting of the Board of Directors  on April 8, 1999,  the Board also
reviewed certain prior actions of the Board.

     The Board  placed a stop  transfer  order on the 200,000  shares  issued to
Mytec & Associates  because the assignment of the Henderson  leasehold was never
made to the Company and they were in default on their agreement.

     The Board  rescinded a  distribution  of a portion of the five percent (5%)
overriding  royalty  interest  granted to several Board  members,  employees and
consultants  in February  1999 when the Company  was not  otherwise  able to pay
their salaries and fees. The original  passage of such resolution was based upon
a mistaken  interpretation of the ability of the Board to disburse a substantial
corporate asset on its own action.

     The Board rescinded a conditional issuance of 3,000,000 shares to Mr. Bass,
Mr.  Callender  and Noreen  Wilson in June 1997 relative to Sao Tome and certain
production levels.

     The Board rescinded a conditional issuance granted under the MIII agreement
in July 1997 because certain obligations of the Seller under such agreement were
not met and they was a default.

     The Board reviewed the extraordinary efforts of certain of its officers and
directors  in assuring  the  formation of STPETRO,  having  STPETRO's  formation
enacted into law and in negotiating the Technical  Assistance  Agreement between
STPETRO and Mobil.  In  appreciation  of such  efforts,  the Board  approved the
issuance of 2,000,000  shares of the  Company's  restricted  Common Stock to Mr.
Bass, Mr. Callender, Ms. Wilson and Mr. Griffin.

     As part of the  Letter  of  Intent,  the  Company  was  required  to secure
Standstill  Agreements from its noteholders.  Certain of the noteholders elected
to convert their notes, including principal,  interest and penalties into Common
Stock  rather  than  execute the  Standstill  Agreement.  Of these,  $750,000 of
principal notes were converted from the October 1997  Financing,  and all of the
remaining  notes from the  July/August  1998  Financing  were converted with the
exception of a total of $660,000 in face value which remains  outstanding.  Such
conversions resulted in the authorization on April 23, 1999 to issue 17, 472,989
shares  of the  Company's  restricted  Common  Stock  based  upon  the  relevant
conversion  prices  on the dates of the  conversion  notices,  with the  holding
period  commencing on the date each applicable note was issued. Of the remaining
unconverted notes, all of the noteholders executed Standstill Agreements.

     The meeting  continued with the Board  authorizing the issuance of warrants
in settlement of certain  outstanding issues with one of its consultants,  which
warrants are exercisable into 414,125 shares of restricted Common Stock.

     Also, the Company authorized the issuance of 12,294,674 shares to cover the
accrued  interest and penalties on all of the note  transactions  as required by
the Standstill Agreements.

     After the election of the new  Officers and three (3) New  Directors at the
meeting of the Board on April 30, 1999,  the four (4)  remaining  Board  members
recused themselves when the New Directors voted upon the Consulting  Agreements,
Severance  Agreement and Settlement  Agreements with such remaining  members and
former Officer,  Directors,  Employees and Consultants of the Company since such
remaining  Board  members  clearly had a vested  interest in the outcome of such
vote.  Such members also recused  themselves  while the New Directors voted upon
certain  settlements  negotiated  with various  parties  relative to outstanding
claims and issues involving the Company,  since such remaining Board members had
not participated in these negotiations.

     Pursuant to the Consulting Agreements,  Severance Agreements and Settlement
Agreements,  11,245,000  shares of restricted Common Stock were authorized to be
issued to former  Officers,  current and former Directors and current and former
Consultants  of which  6,770,000  shares were taken in lieu back salaries due to
Noreen  Wilson and James  Griffin.  In  addition,  pursuant  to such  Consulting
Agreements, Severance Agreements and Settlement Agreements, warrants to purchase
4,725,000 shares of the Company's  restricted Common Stock were authorized to be
granted to former Officers,  current and former Directors and current and former
Consultants,  which warrants  contain  graduated  exercise prices of $.25, $.50,
$.75, $1.00 and $1.25 and require exercise within a period of four (4) years.

     Subsequent to the execution of the Letter of Intent,  ERHCIG had negotiated
settlements  of a number of  outstanding  matters which it felt were in the best
interest of the Company.  Ms. Wilson, a former director of the Company,  elected
to take a  convertible  note in exchange for unpaid  expenses.  Ms.  Wilson is a
member of ERHCIG and has certain  shareholdings  relative to such participation.
Pursuant to the negotiated  settlements,  3,143,665  shares of Common Stock were
authorized,  including  shares  equal to  $700,000  at $.20 per share in lieu of
repayment of a loan made to the Company by an outside  party.  In addition,  the
New Directors  granted  warrants to purchase  1,000,000  shares of the Company's
Common Stock  exercisable at $.25,  which warrants  expire in April,  2009, to a
noteholder in the October 1997  Financing and the  September  1998  Financing in
exchange  for  its   assistance  in  putting   together  the  Letter  of  Intent
transaction..

     After all actions taken  through April 30, 1999 and before  issuance of the
shares  under the  Subscription  Agreement,  the  total  number of shares of the
Company's  Common  Stock  authorized  for  issuance is  89,464,630.  Taking into
consideration all outstanding  convertible  notes,  warrants and options and the
total  authorized  number of shares  for  issuance,  on a fully  diluted  basis,
146,357,210 shares of Common Stock,  represent the total voting capital stock of
the Company for purposes of determining  49%. This is without any  consideration
for additional shares to Procura Financial  Consultants for settlement above the
2,000,000 shares already held by the Company.

     The Company received subscription  agreements dated as of April 27, 1999 on
May 14, 1999 from ERHCIG. Pursuant to such agreements,  ERHC Investor Group LLC,
ERHC Investor  Group A and ERHC Investor  Group II have  committed to purchase a
total of 51% of the Company's restricted Common Stock, on a fully diluted basis,
in exchange for the payment of $3,000,000. In the event that a Final Closing, as
defined in the Letter of Intent,  does not occur within  ninety (90) days,  ERHC
Investor Group LLC will surrender to the Company, for cancellation, such rights


<PAGE>



as it has or such certificates as it has received less an amount of shares which
it will retain in consideration of the payments which it has made. The amount to
be retained  shares  will be based upon a  $5,882,352  valuation  of the Company
after  adjustment  for the  actions of the Board of  Directors  relative  to the
realign of BAPCO and its transfer to the corporation held for the benefit of Sam
Bass or his assigns.  Accordingly,  an additional  152,330,974  shares of Common
Stock are required to be issued in order to cover 51% on a fully diluted basis.

Item 3.   Defaults Upon Senior Securities

     None. The Company was in default in the payment of the principal due on the
notes issued in the April 1998 Financing.  These notes were due in January 1999;
however, under the terms of the Standstill Agreement with these noteholders, the
principal payment has been deferred until December 1999.

     A  requirement  of funding  provided to the Company in November,  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
owed the Avalon investors penalty payments from March 1998 to the present. 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.

     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 June 2000 (the "Third
June 1998  Notes") and  warrants to purchase  shares of Common Stock (the "Third
June 1998 Warrants") to one "accredited" investor.  Pursuant to the terms of the
agreements,  certain  penalties  were to be paid to the  Third  June  1998  Note
Investor in the event the registration  statement was not effective within sixty
days.  In lieu of such  payments,  the Investor  has elected to take  additional
shares in full liquidation of all penalties due through February 1999.

     In July and August 1998,  the Company  raised gross proceeds of $1,200,000,
$275,000 and $1,010,000  respectively in a private placement of up to $3,000,000
in three(3)  tranches of the Company's  8.0%  convertible  notes due in July and
August 2000 (the "July Notes") to a limited  number of  "accredited"  investors.
Warrants were issued to the placement agent at the close of each tranche  (the


<PAGE>



"July  Warrants").  The Company has failed to register the shares into which the
July Notes are  convertible  and the July  Warrants are  exercisable  during the
60-day period  following the  completion of this  transaction as required by the
agreements. As a result, the Company is required to make certain payments to the
July/August Investors.

     As part of the Standstill Agreements, the Company agreed to issue shares of
Common  Stock  sufficient  to make it current on all  outstanding  interest  and
penalties  for  all of the  convertible  note  transactions.  Pursuant  to  such
agreements,  the  Company is current  on all of its debt  obligations.  Further,
pursuant to such agreements,  the noteholders have waived interest and penalties
through October 15, 1999.

Item 4.   Submission of Matters to a Vote of Security Holders

           None

Item 5    Other Information

     On February 16, 1999, the Company reported that subsequent to the filing of
the  Company's  S-1/A3 and  Amendment  No. 1 to the Form 10K for the Fiscal Year
Ended September 30, 1998 ("10K/A1"), it was discovered that there was a question
of the  ownership  rights  of the  Company  in the BAPCO  tool and other  assets
acquired from Sam Bass and his companies which created a cloud upon the title to
such assets (the "February 8-K").

     The  Board of  Directors  of the  Company  was given  notice  by  Durland &
Company,  CPAs, P.A., under Section 10A(b)(2) of the Securities and Exchange Act
of 1934 and  filed the  February  8-K in  compliance  with the  requirements  of
Section 10A(b)(3).

     The Company and its independent  auditors,  Durland & Company,  CPAs, P.A.,
conducted  a full  investigation.  It was  determined  that it would  cause  the
Company  undue  hardship to try to clarify and correct the cloud on the title to
the assets acquired from Sam Bass and his related companies and that the process
of  such  clarification  might  result  in  protracted  litigation.   The  Board
determined  that the best  course for the Company  and its  shareholders  was to
realign  certain  of its  assets  between  itself  and  BAPCO,  to  rescind  the
transactions  with Mr. Bass and his related  companies and to transfer BAPCO, as
realigned, to a new corporation held for the benefit of Mr. Bass or his assigns.
Upon return of the shares  issued in the rescinded  transactions,  the shares in
the new corporation are to be released to Mr. Bass or his assigns.

     On April 8, 1998,  the Company and BAPCO  entered into an  agreement  which
provided the following:

a.   BAPCO assigned all rights, title and interest, if any, which it had to ERHC
     in the leases in the Uintah  property,  the  Wichita  Falls  property,  the
     Nueces  property  and  the  MIII  property,  consented  to  the  use of the
     agreement as evidence of such assignment and authorized ERHC to perfect the
     assignment  of interest and to execute any and all  documents  necessary to
     perfect such assignment on its behalf and in its name.



<PAGE>



b.   BAPCO  consented to its removal as the  operator on the leases  assigned to
     ERHC in  accordance  with  paragraph 1 above,  consented  to the use of the
     agreement as evidence of such consent and  authorized  ERHC to perfect such
     removal  and to execute any and all  documents  necessary  to perfect  such
     removal on its behalf and in its name.

c.   ERHC assigned all rights,  title and interest,  if any, which it had in the
     Schellstede-Lee,  LLC  license  to BAPCO,  which  license  is paid  through
     October 16, 1998.

d.   ERHC assumed the liability for the accounts  payable  previously in BAPCO's

<PAGE>



     assigns  until  such  time  as (1)  Mr.  Bass  tendered  the  four  million
     (4,000,000) shares issued to him at the acquisition of BAPCO in April 1997,
     (2) Mr. Bass and/or Bass World Wide  Services  tendered  the seven  hundred
     forty  four  (744,000)  shares  issued to them for the  acquisition  of the
     environmental remediation equipment, (3) Mr. Bass and/or Bass Environmental
     Services  Worldwide  Inc.  tendered the three  million  (3,000,000)  shares
     issued to them for the  acquisition of the Chevron  Agreement,  and (4) Mr.
     Bass, Bass World Wide Services and Bass  Environmental  Services  Worldwide
     Inc.  executed  and  delivered a full and general  release in favor of ERHC
     relinquishing,  among other things, all claims relative to such shares, the
     original  acquisition of such assets and the transfer of BAPCO as realigned
     and its  assets  and all  claims  relative  to any  part of the  overriding
     royalty interest previously granted to him relative to Sao Tome.

c.   At such time as  NEWBASSCORP  received  tender  of any of the  shares to be
     relinquished  in accordance  with paragraph 2 above and the delivery of the
     full and  general  release,  NEWBASSCORP  agreed to return  such shares and
     release to ERHC forthwith and to deliver the pro rata portion of the shares
     in NEWBASSCORP  held for the benefit of Mr. Bass or his assigns to Mr. Bass
     or to his designated assignee.

d.   NEWBASSCORP  released  and  discharged  ERHC  from all  claims  or  actions
     relative  to  the  original   acquisition  of  BAPCO,   the   environmental
     remediation equipment, the Chevron Agreement and the issuance of shares for
     each such acquisition and accepted the assignment as full consideration for
     the transaction subject only to the full obligation of ERHC relative to the
     specific liabilities assumed.

     By Agreement  effective April 23, 1999 between the White Cloud Development,
Inc.  ("White  Cloud")  and  Sam  Bass,  individually  and  on  behalf  of  Bass
Environmental Worldwide Services Inc., Mr. Bass exchanged and released 7,744,000
shares of the Company's  restricted  stock for 100% of the authorized and issued
capital stock in White Cloud. Mr. Bass delivered the Company's restricted shares
previously issued to him and the required release to White Cloud.

     The Company does not believe that there need be any changes in the legal or
financial  disclosure  relative  to  the  financial  and  legal  effects  of the
rescission of the related party agreements with Mr. Bass and his companies which
would require further amendment to its Form S-1 and Form 10K for the Fiscal Year
Ended September 30, 1998 and all other reports which has been filed since.

     In addition,  on May 21, 1999, the Company filed on Form 8K a report of the
change of control and the  rescission  of the Bass  related  transactions.  Such
report  stated  that no  changes  have  been  made to the  legal  and  financial
disclosure  as  a  result  of  the  completion  of  the  investigation  and  the
realignment of BAPCO.

     All parties may continue to rely upon the  previously  filed audit  opinion
letter,  financial statements and the disclosures as to the BAPCO tool contained
in the Company's Form S-1/A3 and the Form 10K/A1.  The Company  intends to file,
within sixty (60) days of this Form 8K, a pro forma statement for the periods

ending  September  30,  1998 and March  31,  1999  showing  the  effects  of the

Exhibit 10.35.1

STANDSTILL AGREEMENT

     THIS AGREEMENT  effective as provided  herein by and between  ENVIRONMENTAL
REMEDIATION HOLDING CORPORATION ("ERHC"), a Colorado  corporation,  with offices
at 1686 General  Mouton Avenue,  Lafayette,  LA 70508 and the Investors or their
permitted assigns whose names are included in Schedule A annexed hereto and made
a part hereof (collectively the "Investors" or individually, the "Investor").

     WHEREAS,  ERHC and the Investors  executed a Securities  Purchase Agreement
and  Registration  Rights Agreement both dated October 15, 1997 under which ERHC
issued  its 5.5%  convertible  notes  due  October  2002 (the  "Notes),  granted
warrants  to purchase  ERHC's  common  stock with an exercise  date on or before
October 15, 2002 (the  "Warrants")  and agreed to file a Registration  Statement
with the Securities and Exchange  Commission  ("SEC")  relative to the Notes and
Warrants (the "SPA" and "RRA" respectively) ; and

     WHEREAS,  ERHC has  executed  and its Board of  Directors  have  approved a
letter of intent  dated April 8, 1999 with ERHC  Investment  Group,  Inc.  which
requires certain consents from the Investors and amendments and modifications to
the SPA,  RRA the Notes and the  Warrants,  a copy of which  letter of intent is
annexed hereto and made a part hereof as Exhibit A (the "Letter of Intent"); and

     WHEREAS,  the parties wish to confirm in writing  their  understanding  and
agreement regarding these matter.

     NOW THEREFORE in consideration of the mutual promises  contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties agree as follows:

1.   Confidential   Information.   Investors'   consent   and   amendments   and
     modifications  to theSPA,  RRA, Notes and Warrant as provided in the Letter
     of Intent are conditions  precedent to the Initial Closing.  This is due to
     the fact that the Notes and  Warrants  have certain  adjustments  which may
     render it  impossible  for ERHC to issue  the  requisite  control  interest
     required  under the term of the Letter of  Intent.  The  matters  contained
     herein  and in the  Letter  of  Intent  are  confidential  information  not
     available  to the  public.  These  matters  will only be made public with a
     filing  by ERHC of a Form 8K  within  the time  required  from the  Initial
     Closing as defined in the Letter of Intent  (the  "Initial  Closing"),  the
     date on which an 8K event takes place. Accordingly, the Investors expressly
     agree not to disclose,  use or trade on this information either directly or
     indirectly  in any  manner  until such time as the Form 8K  reporting  this
     Letter of Intent is filed with the SEC.

2.   Amendments  and  Modifications.  The SPA provides  that upon the vote of 66
     2/3% of the Investors under such agreement, any of the terms and conditions
     of the SPA,  RRA, the Notes and the Warrants may be amended or modified,


<PAGE>



     provided such amendment or  modification  is in writing and executed by not
     less  than 66 2/3% of the  Investors.  In such  event,  the  amendment  and
     modification  will  be  effective  as to all of the  Investors  under  such
     agreement. In the event that 66 2/3% of the Investors under the SPA execute
     this Agreement,  and except as otherwise  specifically provided for herein,
     from the date of the  Initial  Closing  under the Letter of  Intent,  it is
     agreed that the following terms and conditions are amended and modified:

                    the amount of interest due divided by the Conversion Price.

               2.   In  addition  to  the  amendment  to  paragraph   1(b),  the

                    thereafter until October 15, 1999.

               3.   The  provisions  for  voluntary   conversion   contained  in

               5.   The adjustments of Conversion Price in paragraph 5(d) of the
                    Notes are deleted in their  entirety  and the text set forth
                    in  Exhibit  B  annexed   hereto  and  made  a  part  hereof

                                    EXHIBIT B

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 .

     (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  (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 (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


<PAGE>



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 (i), (ii) and
(iii), or a reorganization,  merger,  consolidation,  or sale of assets provided
for in Section (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 (i), (ii) and (iii), or a reclassification,  exchange or substitution of
shares  provided  for in  Section  (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 (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  (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.

                                    EXHIBIT C

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

     (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 (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 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  (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,


<PAGE>



exchange,  substitution  or  otherwise  (other  than by way of a stock  split or
combination of shares or stock  dividends  provided for in Sections (a), (b) and
(c), or a reorganization,  merger, consolidation, or sale of assets provided for
in Section (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 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 (a), (b), and (c), or a  reclassification,  exchange or  substitution of
shares provided for in Section (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 (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  (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.







Exhibit 10.35.2

STANDSTILL AGREEMENT

     THIS AGREEMENT  effective as provided  herein by and between  ENVIRONMENTAL
REMEDIATION HOLDING CORPORATION ("ERHC"), a Colorado  corporation,  with offices
at 1686 General  Mouton Avenue,  Lafayette,  LA 70508 and the Investors or their
permitted assigns whose names are included in Schedule A annexed hereto and made
a part hereof (collectively the "Investors" or individually, the "Investor").

     WHEREAS,  ERHC issued its 12.0% convertible notes due on the earlier of the
date upon which the Company  accepted the first take down under the  Kingsbridge
Equity  Line of Credit or January  1999 (the  "Notes)  and  granted  warrants to
purchase  ERHC's  common stock with an exercise date on or before April 12, 2001
(the "Warrants"); and

     WHEREAS,  ERHC has  executed  and its Board of  Directors  have  approved a
letter of intent  dated April 8, 1999 with ERHC  Investment  Group,  Inc.  which
requires certain consents from the Investors and amendments and modifications to
the Notes and the Warrants,  a copy of which letter of intent is annexed  hereto
and made a part hereof as Exhibit A (the "Letter of Intent"); and

     WHEREAS,  the parties wish to confirm in writing  their  understanding  and
agreement regarding these matter.

     NOW THEREFORE in consideration of the mutual promises  contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties agree as follows:

1.   Confidential   Information.   Investors'   consent   and   amendments   and
     modifications to the Notes and Warrants as provided in the Letter of Intent
     are conditions  precedent to the Initial  Closing.  This is due to the fact
     that the Notes and Warrants  have certain  adjustments  which may render it
     impossible for ERHC to issue the requisite  control interest required under
     the term of the Letter of Intent.  The matters  contained herein and in the
     Letter of Intent are confidential  information not available to the public.
     These  matters  will only be made public with a filing by ERHC of a Form 8K
     within the time required from the Initial  Closing as defined in the Letter
     of Intent  (the  "Initial  Closing"),  the date on which an 8K event  takes
     place.  Accordingly,  the Investors expressly agree not to disclose, use or
     trade on this information either directly or indirectly in any manner until
     such time as the Form 8K reporting  this Letter of Intent is filed with the
     SEC.

2.   Amendments and  Modifications.  From the date of the Initial  Closing under
     the Letter of Intent,  it is agreed that the following terms and conditions
     are amended and modified:

          A.   The Notes are amended and modified as follows:


<PAGE>




               1.   The Maturity  Date of the Notes set forth in paragraph  1(a)
                    is amended to be December 31, 1999.

               2.   The provision for payment of interest contained in paragraph
                    1(b) is amended to permit,  in addition to the other methods
                    of payment contained therein, for the payment of interest in
                    the form of shares in common stock in an amount equal to the
                    amount of interest due divided by the Conversion Price.

               3.   In  addition  to  the  amendment  to  paragraph   1(b),  the
                    following will be added to such paragraph:  "Notwithstanding
                    any  other  provision  contained  in  this  paragraph  1(b),
                    interest is waived from the date of the Initial  Closing and
                    thereafter until October 15, 1999.

               4.   The  provisions  for  voluntary   conversion   contained  in
                    paragraph  4(a)  is  amended  to  permit,   in  addition  to
                    conversion  of  all  or a  portion  of the  Notes,  for  the
                    conversion of outstanding  interest and  penalties,  if any,
                    into  Common  Stock at the time a  voluntary  conversion  of
                    principal  is made for the  amount  of  interest  due on the
                    Notes.

               5.   The  Conversion  Price  in  paragraph  4(b) of the  Notes is
                    amended to be $0.25.

          C.   In addition to the foregoing  amendments and  modifications,  the
               Investors consent and agree to the following additional terms:

               1.   From the date of the Initial  Closing and  thereafter  until
                    October  15,  1999 (i) not to convert all or any part of the
                    Notes, (ii) not to declare a default or seek acceleration of
                    any  payments  under the Notes,  (iii) not to  commence  any
                    collections  actions or proceedings under the Notes (iv) not
                    to commence any foreclosure or bankruptcy  actions under the
                    Notes  and  (v) not to  declare  any  Event  of  Default  or
                    commence any arbitration action under the Notes or Warrants.

               2.   From the date of execution of this  Agreement,  to waive all
                    rights under any  adjustments,  antidilution  provisions  or
                    preemptive  rights  previously   granted  in  the  Notes  or
                    Warrants or provided by these  amendments and  modifications
                    (i) relative to the  transaction  contemplated in the Letter
                    of Intent or (ii)  relative to any  settlement  with Procura
                    Financial  entered  into by the  Company  upon  commercially
                    reasonable terms to complete the assignment of rights, title
                    and interest in Sao Tome in favor of the Company.

               3.   Through  the  Initial  Closing,  to accept  shares of Common
                    Stock for all accrued and unpaid  interest and  penalties on
                    the Notes as of the Initial  Closing,  which shares shall be
                    delivered within ten (10) days of the Closing Date.

               4.   From the date of execution of this  Agreement and thereafter
                    until  October  15,  1999,  to vote with the  Company in the
                    event  that any third  party,  other  than each of the other
                    note and warrant holders listed as a Selling  Shareholder in
                    Amendment  No.  3 to the  Form  S- 1  filed  with  the  SEC,
                    commences any bankruptcy or  foreclosure  action against the
                    Company or any of its subsidiaries.

3.   Effects  of No Closing  under the  Letter of  Intent.  In the event that no
     Closing as defined in the Letter of Intent (the  "Closing")  occurs  within
     ninety  (90) days from the date of the  Initial  Closing,  the  amendments,
     modifications  and  consents in paragraph 2 above shall be null and void ab
     initio.

4.   ERHC Representations and Warranties.  ERHC represents and warrants that the
     amendments,  modifications  and  consents  set  forth  in  paragraph  2 are
     substantially similar to the amendments,  modifications and consents sought
     from each of the  other  convertible  note and  warrant  holders  listed as
     Selling  Shareholders in the Amendment No. 3 to the Form S-1 filed with the
     SEC and differ only in those matters  which are specific to any  particular
     note or warrant transaction listed therein.

5.   Effect upon Other Terms and Conditions.  Notwithstanding the amendments and
     modifications  contained  herein,  it is  expressly  agreed by the  parties
     hereto that all other terms,  conditions  and  provisions  of the Notes and
     Warrants remain in full force and effect.

6.   Ratification.  The Investors ratify the acts of and hold harmless the Board
     of Directors and Officers for all actions taken by them in compliance  with
     the  interpretations  of any  court  of  competent  jurisdiction  as to the
     application  of the  Business  Judgement  Rule from  inception  through the
     Initial Closing Date.

Exhibit 10.35.3

STANDSTILL AGREEMENT

           THIS   AGREEMENT   effective  as  provided   herein  by  and  between
ENVIRONMENTAL  REMEDIATION HOLDING CORPORATION ("ERHC"), a Colorado corporation,
with  offices  at 1686  General  Mouton  Avenue,  Lafayette,  LA  70508  and the
Investors  or their  permitted  assigns  whose names are  included in Schedule A
annexed  hereto  and  made  a  part  hereof  (collectively  the  "Investors"  or
individually, the "Investor").

           WHEREAS,  on June 1, 1998 ERHC  granted  warrants to purchase  ERHC's
common stock with an exercise  date on or before  fourteen  (14) months from the
effective date of a Registration Statement covering the warrants, which warrants
also  contained  rights for the  holders to be granted  additional  warrants  in
certain circumstances (the "Warrants"); and

           WHEREAS, ERHC has executed and its Board of Directors have approved a
letter of intent  dated April 8, 1999 with ERHC  Investment  Group,  Inc.  which
requires certain consents from the Investors and amendments and modifications to
the Warrants, a copy of which letter of intent is annexed hereto and made a part
hereof as Exhibit A (the "Letter of Intent"); and

           WHEREAS,  the parties wish to confirm in writing their  understanding
and agreement regarding these matter.

           NOW  THEREFORE  in  consideration  of the mutual  promises  contained
herein and for other good and valuable  consideration,  the receipt and adequacy
of which are hereby acknowledged, the parties agree as follows:

     1.   Confidential  Information.   Investors'  consent  and  amendments  and
          modifications  to the Warrants as provided in the Letter of Intent are
          conditions  precedent to the Initial Closing.  This is due to the fact
          that the  Warrants  have  certain  adjustments  which  may  render  it
          impossible for ERHC to issue the requisite  control interest  required
          under the term of the Letter of Intent.  The matters  contained herein
          and in the Letter of Intent are confidential information not available
          to the public. These matters will only be made public with a filing by
          ERHC of a Form 8K within the time required from the Initial Closing as
          defined in the Letter of Intent (the "Initial  Closing"),  the date on
          which an 8K event takes place.  Accordingly,  the Investors  expressly
          agree  not to  disclose,  use or  trade  on  this  information  either
          directly or  indirectly  in any manner  until such time as the Form 8K
          reporting this Letter of Intent is filed with the SEC.

     2.   Amendments  and  Modifications.  From the date of the Initial  Closing
          under the Letter of Intent,  it is agreed that the following terms and
          conditions are amended and modified:

          A.   The Warrants are amended and modified as follows:



<PAGE>



               1.   The  antidilution  provisions in Article III,  paragraph 3.2
                    and 3.4 of the  Warrants  are deleted in their  entirety and
                    the text set forth in Exhibit B substituted in their place.

               2.   Article III, paragraph 3.3 is deleted in its entirety.

          B.   In addition to the foregoing  amendments and  modifications,  the
               Investors consent and agree to the following additional terms:

               1.   From the date of execution of this  Agreement,  to waive all
                    rights under any  adjustments,  antidilution  provisions  or
                    preemptive  rights  previously  granted in the  Warrants  or
                    provided by these  amendments and  modification (i) relative
                    to the  transaction  contemplated in the Letter of Intent or
                    (ii)  relative  to any  settlement  with  Procura  Financial
                    entered  into by the Company  upon  commercially  reasonable
                    terms to complete the  assignment  of all rights,  title and
                    interest in Sao Tome in favor of the Company.

               2.   From the date of execution of this  Agreement and thereafter
                    until  October  15,  1999,  to vote with the  Company in the
                    event  that any third  party,  other  than each of the other
                    note and warrant holders listed as a Selling  Shareholder in
                    Amendment  No.  3 to the  Form  S- 1  filed  with  the  SEC,
                    commences any bankruptcy or  foreclosure  action against the
                    Company or any of its subsidiaries.

3.   Effects  of No Closing  under the  Letter of  Intent.  In the event that no
     Closing as defined in the Letter of Intent (the  "Closing")  occurs  within
     ninety  (90) days from the date of the  Initial  Closing,  the  amendments,
     modifications  and  consents in paragraph 2 above shall be null and void ab
     initio.

4.   ERHC Representations and Warranties.  ERHC represents and warrants that the
     amendments,  modifications  and  consents  set  forth  in  paragraph  2 are
     substantially similar to the amendments,  modifications and consents sought
     from each of the  other  convertible  note and  warrant  holders  listed as
     Selling  Shareholders in the Amendment No. 3 to the Form S-1 filed with the
     SEC and differ only in those matters  which are specific to any  particular
     note or warrant transaction listed therein.

5.   Effect upon Other Terms and Conditions.  Notwithstanding the amendments and
     modifications  contained  herein,  it is  expressly  agreed by the  parties
     hereto that all other  terms,  conditions  and  provisions  of the Warrants
     remain in full force and effect.

6.   Ratification.  The Investors ratify the acts of and hold harmless the Board
     of Directors and Officers for all actions taken by them in compliance  with
     the  interpretations  of any  court  of  competent  jurisdiction  as to the
     application  of the  Business  Judgement  Rule from  inception  through the
     Initial Closing Date.

     intended  beneficiaries of this Agreement.  In the event of any breach, the
     parties and the intended  beneficiaries  of this  Agreement  shall have all
     remedies  available  at  law or in  equity  including  the  right  to  seek
     injunctive relief.

8.   Effective Date. This Agreement shall be effective and binding upon ERHC and
     the each  Investor  set forth in Schedule A  individually  from the date of
     execution by each Investor.

     be binding upon and inure to the benefit of each party's heirs,  executors,

     venue set forth in the Warrants shall remain in full force and effect.

     each of which when taken  together shall  represent one binding  agreement.
     Delivery  of an  executed  counterpart  hereof via  telecopier  shall be as

                                    EXHIBIT B

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

     (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 (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 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  (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,


<PAGE>



exchange,  substitution  or  otherwise  (other  than by way of a stock  split or
combination of shares or stock  dividends  provided for in Sections (a), (b) and
(c), or a reorganization,  merger, consolidation, or sale of assets provided for
in Section (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 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 (a), (b), and (c), or a  reclassification,  exchange or  substitution of
shares provided for in Section (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 (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  (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.








Exhibit 10.35.4

STANDSTILL AGREEMENT

     THIS AGREEMENT  effective as provided  herein by and between  ENVIRONMENTAL
REMEDIATION HOLDING CORPORATION ("ERHC"), a Colorado  corporation,  with offices
at 1686 General  Mouton Avenue,  Lafayette,  LA 70508 and the Investors or their
permitted assigns whose names are included in Schedule A annexed hereto and made
a part hereof (collectively the "Investors" or individually, the "Investor").

     WHEREAS,  ERHC issued its 12.0% convertible notes due on the earlier of the
date upon  which the  Company  received  debt or equity  financing  in excess of
$4,000,000  or December 31, 1999 (the  "Notes) and granted  warrants to purchase
ERHC's  common  stock  with an  exercise  date on or before  June 18,  2002 (the
"Warrants"); and

     WHEREAS,  ERHC has  executed  and its Board of  Directors  have  approved a
letter of intent  dated April 8, 1999 with ERHC  Investment  Group,  Inc.  which
requires certain consents from the Investors and amendments and modifications to
the Notes and the Warrants,  a copy of which letter of intent is annexed  hereto
and made a part hereof as Exhibit A (the "Letter of Intent"); and

     WHEREAS,  the parties wish to confirm in writing  their  understanding  and
agreement regarding these matter.

     NOW THEREFORE in consideration of the mutual promises  contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties agree as follows:

1.   Confidential   Information.   Investors'   consent   and   amendments   and
     modifications to the Notes and Warrants as provided in the Letter of Intent
     are conditions  precedent to the Initial  Closing.  This is due to the fact
     that the Notes and Warrants  have certain  adjustments  which may render it
     impossible for ERHC to issue the requisite  control interest required under
     the term of the Letter of Intent.  The matters  contained herein and in the
     Letter of Intent are confidential  information not available to the public.
     These  matters  will only be made public with a filing by ERHC of a Form 8K
     within the time required from the Initial  Closing as defined in the Letter
     of Intent  (the  "Initial  Closing"),  the date on which an 8K event  takes
     place.  Accordingly,  the Investors expressly agree not to disclose, use or
     trade on this information either directly or indirectly in any manner until
     such time as the Form 8K reporting  this Letter of Intent is filed with the
     SEC.

2.   Amendments and  Modifications.  From the date of the Initial  Closing under
     the Letter of Intent,  it is agreed that the following terms and conditions
     are amended and modified:



<PAGE>



     A.   The Notes are amended and modified as follows:

          1.   The provision for payment of interest contained in paragraph 1(b)
               is deleted  and in its place shall read  "Interest  on the unpaid
               balance of this Note at the rate of twelve  percent  (12.0%)  per
               annum  shall  accrue from the date hereof and shall be payable on
               the earlier of (i) the Maturity Date or (ii) the Conversion  Date
               as to all or that portion of the Note converted in cash or in the
               form of shares in common  stock in an amount  equal to the amount
               of interest due divided by the Conversion  Price. The Company may
               elect to make accrued  interest  payments at any time in the form
               of  shares in common  stock in an amount  equal to the  amount of
               interest due to date  divided by the  Conversion  Price.  In such
               event,  only interest  which  accrues from such election  payment
               shall be payable on any  subsequent  election date or on maturity
               or conversion."

          2.   In addition to the  amendment to paragraph  1(b),  the  following

          3.   The  provisions for voluntary  conversion  contained in paragraph
               4(a) is amended to permit,  in addition to conversion of all or a
               portion of the Notes, for the conversion of outstanding  interest
               and penalties,  if any, into Common Stock at the time a voluntary
               conversion of principal is made for the amount of interest due on
               the Notes.

          4.   The Conversion Price in paragraph 4(b) of the Notes is amended to
               be $0.25.

     C.   In  addition  to  the  foregoing  amendments  and  modifications,  the
          Investors consent and agree to the following additional terms:

           EDWARD R. ROLQUIN

           DAVID B. THORNBURGH

Exhibit 10.35.5

STANDSTILL AGREEMENT

     THIS AGREEMENT  effective as provided  herein by and between  ENVIRONMENTAL
REMEDIATION HOLDING CORPORATION ("ERHC"), a Colorado  corporation,  with offices
at 1686 General  Mouton Avenue,  Lafayette,  LA 70508 and the Investors or their
permitted assigns whose names are included in Schedule A annexed hereto and made
a part hereof (collectively the "Investors" or individually, the "Investor").

     WHEREAS,  ERHC and the Investors  executed a Securities  Purchase Agreement
and  Registration  Rights  Agreement  both dated June 24,  1998 under which ERHC
issued  its 5.5%  convertible  notes  due June 23,  2000 (the  "Notes),  granted
warrants to purchase ERHC's common stock with an exercise date on or before June
23, 2003 (the  "Warrants") and agreed to file a Registration  Statement with the
Securities and Exchange  Commission  ("SEC")  relative to the Notes and Warrants
(the "SPA" and "RRA" respectively) ; and

     WHEREAS,  ERHC has  executed  and its Board of  Directors  have  approved a
letter of intent  dated April 8, 1999 with ERHC  Investment  Group,  Inc.  which
requires certain consents from the Investors and amendments and modifications to
the SPA,  RRA the Notes and the  Warrants,  a copy of which  letter of intent is
annexed hereto and made a part hereof as Exhibit A (the "Letter of Intent"); and

     WHEREAS,  the parties wish to confirm in writing  their  understanding  and
agreement regarding these matter.

     NOW THEREFORE in consideration of the mutual promises  contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties agree as follows:

1.   Confidential   Information.   Investors'   consent   and   amendments   and
     modifications  to the SPA, RRA, Notes and Warrant as provided in the Letter
     of Intent are conditions  precedent to the Initial Closing.  This is due to
     the fact that the Notes and  Warrants  have certain  adjustments  which may
     render it  impossible  for ERHC to issue  the  requisite  control  interest
     required  under the term of the Letter of  Intent.  The  matters  contained
     herein  and in the  Letter  of  Intent  are  confidential  information  not
     available  to the  public.  These  matters  will only be made public with a
     filing  by ERHC of a Form 8K  within  the time  required  from the  Initial
     Closing as defined in the Letter of Intent  (the  "Initial  Closing"),  the
     date on which an 8K event takes place. Accordingly, the Investors expressly
     agree not to disclose,  use or trade on this information either directly or
     indirectly  in any  manner  until such time as the Form 8K  reporting  this
     Letter of Intent is filed with the SEC.

2.   Amendments  and  Modifications.  The SPA provides  that upon the vote of 66
     2/3% of the Investors under such agreement, any of the terms and conditions
     of the SPA,  RRA, the Notes and the Warrants may be amended or modified,


<PAGE>




     provided such amendment or  modification  is in writing and executed by not
     less  than 66 2/3% of the  Investors.  In such  event,  the  amendment  and
     modification  will  be  effective  as to all of the  Investors  under  such
     agreement. In the event that 66 2/3% of the Investors under the SPA execute
     this Agreement,  and except as otherwise  specifically provided for herein,
     from the date of the  Initial  Closing  under the Letter of  Intent,  it is
     agreed that the following terms and conditions are amended and modified:

     A.   The  adjustment  provisions to the terms of the Notes or Warrants,  if
          any, contained in the SPA are deleted.

     B.   The Notes are amended and modified as follows:

          1.   The provision for payment of interest contained in paragraph 1(b)
               is  amended  to permit the  payment  of  interest  in the form of
               shares  in  common  stock in an  amount  equal to the  amount  of
               interest due divided by the Conversion Price.

          2.   In addition to the  amendment to paragraph  1(b),  the  following
               will be  added  to such  paragraph:  "Notwithstanding  any  other
               provision  contained in this paragraph  1(b),  interest is waived
               from the date of the Initial Closing and thereafter until October
               15, 1999.

          3.   The  provisions for voluntary  conversion  contained in paragraph
               5(a) is amended to permit,  in addition to conversion of all or a
               portion of the Notes, for the conversion of outstanding  interest
               amd penalties,  if any, into Common Stock at the time a voluntary
               conversion of principal is made for the amount of interest due on
               the Notes.

          4.   The conversion  formula in paragraph 5(c) of the Notes is deleted
               in its  entirety  and the  following  substituted  in its  place,
               "Subject  to the  Adjustments  from time to time as  provided  in

          5.   The  adjustments  of  Conversion  Price in paragraph  5(d) of the
               Notes are  deleted  in their  entirety  and the text set forth in
               Exhibit B annexed  hereto and made a part hereof  substituted  in
               its place:

     C.   The Warrants are amended and modified as follows:

          1.   The antidilution provisions in paragraphs 2 and 3 of the Warrants
               are deleted in their entirety and the text set forth in Exhibit C
               substituted in its place.



<PAGE>



     D.   The RRA is amended and modified to add the following subparagraph:

          1.   ARTICLE 2, Paragraph  2.2(a) - "(vii)  Notwithstanding  any other
               provision contained in this subparagraph (a) , the penalty and/or
               liquidated damage set forth in this paragraph for failing to have
               ERHC's Registration Statement become effective during a specified
               period of time is waived from the date of the Initial Closing and
               thereafter UNTIL October 15, 1999."

     E.   In  addition  to  the  foregoing  amendments  and  modifications,  the
          Investors consent and agree to the following additional terms:

          1.   From the date of the Initial Closing and thereafter until October
               15,  1999 (i) not to convert  all or any part of the Notes,  (ii)
               not to declare a default  or seek  acceleration  of any  payments

               proceedings under the Notes, (iv) not to commence any foreclosure

               provided by these  amendments and  modifications  (i) relative to
               the  transaction  contemplated  in the  Letter  of Intent or (ii)
               relative to any settlement with Procura Financial entered into by
               the Company upon  commercially  reasonable  terms to complete the

                                    EXHIBIT B

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 .

     (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  (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 (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


<PAGE>



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 (i), (ii) and
(iii), or a reorganization,  merger,  consolidation,  or sale of assets provided
for in Section (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 (i), (ii) and (iii), or a reclassification,  exchange or substitution of
shares  provided  for in  Section  (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 (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  (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.

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 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

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

combination of shares or stock  dividends  provided for in Sections (a), (b) and
(c), or a reorganization,  merger, consolidation, or sale of assets provided for

thereafter  to convert  such Warrant 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

shares provided for in Section (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 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,

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 (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  (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

Exhibit 10.35.6

STANDSTILL AGREEMENT

     THIS AGREEMENT  effective as provided  herein by and between  ENVIRONMENTAL
REMEDIATION HOLDING CORPORATION ("ERHC"), a Colorado  corporation,  with offices
at 1686 General  Mouton Avenue,  Lafayette,  LA 70508 and the Investors or their
permitted assigns whose names are included in Schedule A annexed hereto and made
a part hereof (collectively the "Investors" or individually, the "Investor").

     WHEREAS,  ERHC and the Investors  executed a Securities  Purchase Agreement
and Registration  Rights Agreement at three (3) closings in July and August 1998
under which ERHC issued its 8.0% convertible  notes due July 29, 2000, August 4,
2000 and August 19, 2000 (the  "Notes),  ERHC and J.P.  Carey  executed  Warrant
Agreements  for each of the three (3)  closings  (the  "WA")  under  which  ERHC
granted J.P. Carey warrants to purchase  ERHC's common stock with exercise dates
on or before July 28, 2003,  August 3, 2003 and August 18, 2003 (the "Warrants")
and  ERHC  agreed  to file a  Registration  Statement  with the  Securities  and
Exchange  Commission  ("SEC")  relative to the Notes and Warrants (the "SPA" and
"RRA" respectively) ; and

     WHEREAS,  ERHC has  executed  and its Board of  Directors  have  approved a
letter of intent  dated April 8, 1999 with ERHC  Investment  Group,  Inc.  which
requires certain consents from the Investors and amendments and modifications to
the SPA, WA, RRA the Notes and the Warrants, a copy of which letter of intent is
annexed hereto and made a part hereof as Exhibit A (the "Letter of Intent"); and

     WHEREAS,  the parties wish to confirm in writing  their  understanding  and
agreement regarding these matter.

     NOW THEREFORE in consideration of the mutual promises  contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties agree as follows:

1.   Confidential   Information.   Investors'   consent   and   amendments   and
     modifications  to the SPA,  WA,  RRA,  Notes and Warrant as provided in the
     Letter of Intent are conditions  precedent to the Initial Closing.  This is
     due to the fact that the Notes and Warrants have certain  adjustments which
     may render it impossible for ERHC to issue the requisite  control  interest
     required  under the term of the Letter of  Intent.  The  matters  contained
     herein  and in the  Letter  of  Intent  are  confidential  information  not
     available  to the  public.  These  matters  will only be made public with a
     filing  by ERHC of a Form 8K  within  the time  required  from the  Initial
     Closing as defined in the Letter of Intent  (the  "Initial  Closing"),  the
     date on which an 8K event takes place. Accordingly, the Investors expressly
     agree not to disclose,  use or trade on this information either directly or
     indirectly  in any  manner  until such time as the Form 8K  reporting  this
     Letter of Intent is filed with the SEC.

     provided such amendment or  modification  is in writing and executed by not
     less  than 66 2/3% of the  Investors.  In such  event,  the  amendment  and
     modification  will  be  effective  as to all of the  Investors  under  such
     agreement. In the event that 66 2/3% of the Investors under the SPA execute
     this Agreement,  and except as otherwise  specifically provided for herein,

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 .

     (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  (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 (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


<PAGE>



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 (i), (ii) and
(iii), or a reorganization,  merger,  consolidation,  or sale of assets provided
for in Section (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 (i), (ii) and (iii), or a reclassification,  exchange or substitution of
shares  provided  for in  Section  (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 (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  (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.

     (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 (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 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  (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,


<PAGE>



exchange,  substitution  or  otherwise  (other  than by way of a stock  split or
combination of shares or stock  dividends  provided for in Sections (a), (b) and
(c), or a reorganization,  merger, consolidation, or sale of assets provided for
in Section (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 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 (a), (b), and (c), or a  reclassification,  exchange or  substitution of
shares provided for in Section (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,

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 (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  (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

Exhibit 10.35.7

STANDSTILL AGREEMENT

     THIS AGREEMENT  effective as provided  herein by and between  ENVIRONMENTAL
REMEDIATION HOLDING CORPORATION ("ERHC"), a Colorado  corporation,  with offices
at 1686 General  Mouton Avenue,  Lafayette,  LA 70508 and the Investors or their
permitted assigns whose names are included in Schedule A annexed hereto and made
a part hereof (collectively the "Investors" or individually, the "Investor").

     WHEREAS,  ERHC and the Investors  executed a Securities  Purchase Agreement
dated September 26, 1998 under which ERHC issued its 20.0% convertible notes due
October 26, 2000 (the "Notes),  executed a warrant  agreement ("WA") under which
it granted "A" and "B" warrants to purchase  ERHC's  common stock with  exercise
dates on or before  October  26,  2008  (the  "Warrants")  and  agreed to file a
Registration  Statement  with the  Securities  and Exchange  Commission  ("SEC")
relative to the Notes and Warrants (the "SPA") ; and

     WHEREAS,  ERHC has  executed  and its Board of  Directors  have  approved a
letter of intent  dated April 8, 1999 with ERHC  Investment  Group,  Inc.  which
requires certain consents from the Investors and amendments and modifications to
the SPA,  WA, the Notes and the  Warrants,  a copy of which  letter of intent is
annexed hereto and made a part hereof as Exhibit A (the "Letter of Intent"); and

     WHEREAS,  the parties wish to confirm in writing  their  understanding  and
agreement regarding these matter.

     NOW THEREFORE in consideration of the mutual promises  contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties agree as follows:

1.   Confidential   Information.   Investors'   consent   and   amendments   and
     modifications  to the SPA,  WA, Notes and Warrant as provided in the Letter
     of Intent are conditions  precedent to the Initial Closing.  This is due to
     the fact that the Notes and  Warrants  have certain  adjustments  which may
     render it  impossible  for ERHC to issue  the  requisite  control  interest
     required  under the term of the Letter of  Intent.  The  matters  contained
     herein  and in the  Letter  of  Intent  are  confidential  information  not
     available  to the  public.  These  matters  will only be made public with a
     filing by ERHC of a Form 8K within time required  from the Initial  Closing
     as defined in the Letter of Intent  (the  "Initial  Closing"),  the date on
     which an 8K event takes place.  Accordingly,  the Investors expressly agree
     not to  disclose,  use or  trade on this  information  either  directly  or
     indirectly  in any  manner  until such time as the Form 8K  reporting  this
     Letter of Intent is filed with the SEC.

2.   Amendments  and  Modifications.  The SPA provides  that upon the vote of 66
     2/3% of the Investors under such agreement, any of the terms and conditions
     of the SPA,  WA, the Notes and the  Warrants  may be  amended or  modified,
     provided such amendment or  modification  is in writing and executed


<PAGE>



     by not less than 66 2/3% of the Investors. In such event, the amendment and
     modification  will  be  effective  as to all of the  Investors  under  such
     agreement. In the event that 66 2/3% of the Investors under the SPA execute
     this Agreement,  and except as otherwise  specifically provided for herein,
     from the date of the  Initial  Closing  under the Letter of  Intent,  it is
     agreed that the following terms and conditions are amended and modified:

     A.   The adjustment provisions to the terms of the Notes, Warrant or WA, if
          any, contained in the SPA are deleted.

     B.   The Notes are amended and modified as follows:

          1.   The provision for payment of interest contained in paragraph 1(b)
               is amended to permit, in addition to the other methods of payment
               contained  therein,  for the  payment of  interest in the form of
               shares  in  common  stock in an  amount  equal to the  amount  of
               interest due divided by the  Conversion  Price at the election of
               the Company.

          2.   In addition to the  amendment to paragraph  1(b),  the  following
               will be  added  to such  paragraph:  "Notwithstanding  any  other
               provision  contained in this paragraph  1(b),  interest is waived
               from the date of the Initial Closing and thereafter until October
               15, 1999.

          3.   The conversion  formula in paragraph 4(c) of the Notes is deleted
               in its  entirety  and the  following  substituted  in its  place,
               "Subject  to the  Adjustments  from time to time as  provided  in
               Section 4(d) below, the "Conversion Price" shall mean $0.25.

          4.   The  adjustments  of  Conversion  Price in paragraph  4(d) of the
               Notes are  deleted  in their  entirety  and the text set forth in
               Exhibit B annexed  hereto and made a part hereof  substituted  in
               its place:

C.   The Warrant Agreement is amended and modified as follows:

               Agreement  is deleted in its  entirety  and the text set forth in
               Exhibit C substituted in its place.

D.   In addition to the foregoing  amendments and  modifications,  the Investors
     consent and agree to the following additional terms:

     1.   From the date of the Initial Closing and thereafter  until October 15,
          1999  (i) not to  convert  all or any part of the  Notes,  (ii) not to
          declare a  default  or seek  acceleration  of any  payments  under the
          Notes, (iii) not to commence any collections actions or proceedings


<PAGE>



          under the Notes,  (iv) not to commence any  foreclosure  or bankruptcy
          actions  under the Notes,  and (v) not to declare any Event of Default
          or  commence  any  arbitration  action  under  the SPA,  WA,  Notes or
          Warrants.

     2.   From the date of  execution  of this  Agreement,  to waive all  rights
          under any adjustments,  antidilution  provisions or preemptive  rights
          previously granted in the SPA, Notes,  Warrants,  or WA or provided by
          these  amendments and  modifications  (i) relative to the  transaction
          contemplated  in  the  Letter  of  Intent  or  (ii)  relative  to  any
          settlement  with  Procura  Financial  entered into by the Company upon
          commercially  reasonable  terms  to  complete  the  assignment  of all
          rights, title and interest in Sao Tome in favor of the Company.

     3.   Through the Initial Closing,  to accept shares of Common Stock for all
          accrued  and  unpaid  interest  and  penalties  on the Notes as of the

          of the Closing Date.

     4.   From the date of  execution of this  Agreement  and  thereafter  until
          October 15, 1999, to vote with the Company in the event that any third

          a Selling  Shareholder  in Amendment No. 3 to the Form S- 1 filed with
          the SEC,  commences any bankruptcy or  foreclosure  action against the
          Company or any of its subsidiaries.

3.   Effects  of No Closing  under the  Letter of  Intent.  In the event that no
     Closing as defined in the Letter of Intent (the  "Closing")  occurs  within
     ninety  (90) days from the date of the  Initial  Closing,  the  amendments,
     modifications  and  consents in paragraph 2 above shall be null and void ab
     initio.

4.   ERHC Representations and Warranties.  ERHC represents and warrants that the
     amendments,  modifications  and  consents  set  forth  in  paragraph  2 are
     substantially similar to the amendments,  modifications and consents sought

Any  adjustments  under  this  Section  (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 (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


<PAGE>



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 (i), (ii) and
(iii), or a reorganization,  merger,  consolidation,  or sale of assets provided
for in Section (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 (i), (ii) and (iii), or a reclassification,  exchange or substitution of
shares  provided  for in  Section  (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 (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  (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.

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 (a), (b) and
(c), or a reorganization,  merger, consolidation, or sale of assets provided for

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 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

Section (a), (b), and (c), or a  reclassification,  exchange or  substitution of
shares provided for in Section (d), or a merger or  consolidation of the Company

sale,  to which a holder of Common Stock  deliverable  upon  conversion  of such
shares would have been entitled upon such reorganization, merger, consolidation,

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

Exhibit 10.35.8

STANDSTILL AGREEMENT

     THIS AGREEMENT  effective as provided  herein by and between  ENVIRONMENTAL
REMEDIATION HOLDING CORPORATION ("ERHC"), a Colorado  corporation,  with offices
at 1686 General  Mouton Avenue,  Lafayette,  LA 70508 and the Investors or their
permitted assigns whose names are included in Schedule A annexed hereto and made
a part hereof (collectively the "Investors" or individually, the "Investor").

     WHEREAS, in three (3) closings, ERHC issued its 12.0% convertible notes due
on the earlier of the date upon which the Company  received  $5,000,000 from the
sale of any securities,  assets or rights,  or upon receipt of advance payments,
royalties  or similar  funds or December  31, 1999 (the  "Notes) and  executed a
Warrant  Agreement  under  which it granted "A" and "B"  warrants  (the "WA") to
purchase  ERHC's common stock with exercise dates on or before December 31, 2003
on the "A"  Warrants  and on the earlier of five years from the  exercise of the
"A" Warrants or December 31, 2008 for the "B" Warrants (the "Warrants"); and

     WHEREAS,  ERHC has  executed  and its Board of  Directors  have  approved a
letter of intent  dated April 8, 1999 with ERHC  Investment  Group,  Inc.  which
requires certain consents from the Investors and amendments and modifications to
the  Notes,  WA and the  Warrants,  a copy of which  letter of intent is annexed
hereto and made a part hereof as Exhibit A (the "Letter of Intent"); and

     WHEREAS,  the parties wish to confirm in writing  their  understanding  and
agreement regarding these matter.

     NOW THEREFORE in consideration of the mutual promises  contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties agree as follows:

1.   Confidential   Information.   Investors'   consent   and   amendments   and
     modifications  to the Notes,  WA and  Warrants as provided in the Letter of
     Intent are conditions precedent to the Initial Closing.  This is due to the
     fact that the Notes,  WA and Warrants  have certain  adjustments  which may
     render it  impossible  for ERHC to issue  the  requisite  control  interest
     required  under the term of the Letter of  Intent.  The  matters  contained
     herein  and in the  Letter  of  Intent  are  confidential  information  not
     available  to the  public.  These  matters  will only be made public with a
     filing  by ERHC of a Form 8K  within  the time  required  from the  Initial
     Closing as defined in the Letter of Intent  (the  "Initial  Closing"),  the
     date on which an 8K event takes place. Accordingly, the Investors expressly
     agree not to disclose,  use or trade on this information either directly or
     indirectly  in any  manner  until such time as the Form 8K  reporting  this
     Letter of Intent is filed with the SEC.

2.   Amendments and  Modifications.  From the date of the Initial  Closing under
     the Letter of Intent,  it is agreed that the following terms and conditions
     are amended and modified:

               contained  therein,  for the  payment of  interest in the form of
               shares  in  common  stock in an  amount  equal to the  amount  of
               interest due divided by the  Conversion  Price at the election of
               the Payee.

          2.   In addition to the  amendment to paragraph  1(b),  the  following
               will be  added  to such  paragraph:  "Notwithstanding  any  other
               provision  contained in this paragraph  1(b),  interest is waived
               from the date of the Initial Closing and thereafter until October
               15, 1999.

          3.   The  provisions for voluntary  conversion  contained in paragraph
               4(a) is amended to permit,  in addition to conversion of all or a
               portion of the Notes, for the conversion of outstanding  interest
               and penalties,  if any, into Common Stock at the time a voluntary
               conversion of principal is made for the amount of interest due on
               the Notes.

          4.   The Conversion Price in paragraph 4(b) of the Notes is amended to
               be $0.25.

     B.   The Warrant Agreement is amended and modified as follows:

          1.   The  antidilution  provisions  of  paragraph  11 of  the  Warrant
               Agreement  is deleted in its  entirety  and the text set forth in
               Exhibit B substituted in its place.

     C.   In  addition  to  the  foregoing  amendments  and  modifications,  the
          Investors consent and agree to the following additional terms:

          1.   From the date of the Initial Closing and thereafter until October
               15,  1999 (i) not to convert  all or any part of the Notes,  (ii)
               not to declare a default  or seek  acceleration  of any  payments
               under the Notes, (iii) not to commence any collections actions or
               proceedings  under the Notes (iv) not to commence any foreclosure
               or bankruptcy  actions under the Notes and (v) not to declare any

               Notes, WA or Warrants.

          2.   From the date of execution of this Agreement, to waive all rights
               under any  adjustments,  antidilution  provisions  or  preemptive
               rights  previously  granted in the Notes, WA or Warrants provided
               by  these  amendments  and  modifications  (i)  relative  to  the
               transaction contemplated  in the  Letter of Intent


<PAGE>

               into  by  the  Company  upon  commercially  reasonable  terms  to
               complete the assignment of all rights,  title and interest in Sao
               Tome in favor of the Company.

          3.   Through the Initial Closing, to accept shares of Common Stock for
               all accrued and unpaid  interest and penalties on the Notes as of

               (10) days of the Closing Date.

          4.   From the date of execution of this Agreement and thereafter until
               October 15, 1999,  to vote with the Company in the event that any
               third  party,  other  than  each of the  other  note and  warrant
               holders listed as a Selling Shareholder in Amendment No. 3 to the
               Form S- 1  filed  with  the  SEC,  commences  any  bankruptcy  or

     initio.

4.   ERHC Representations and Warranties.  ERHC represents and warrants that the
     amendments,  modifications  and  consents  set  forth  in  paragraph  2 are
     substantially similar to the amendments,  modifications and consents sought
     from each of the  other  convertible  note and  warrant  holders  listed as
     Selling  Shareholders in the Amendment No. 3 to the Form S-1 filed with the
     SEC and differ only in those matters  which are specific to any  particular
     note or warrant transaction listed therein.

5.   Effect upon Other Terms and Conditions.  Notwithstanding the amendments and
     modifications  contained  herein,  it is  expressly  agreed by the  parties
     hereto that all other terms, conditions and provisions of the Notes, WA and

                                    EXHIBIT B

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

     (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 (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 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

combination of shares or stock  dividends  provided for in Sections (a), (b) and
(c), or a reorganization,  merger, consolidation, or sale of assets provided for

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 (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  (e)  (including  any

           Re:       Subscription Agreement

Ladies and Gentlemen:

     We refer to the letter if intent, dated as of April 8, 1999 (the "Letter of
Intent"), between ERHC Investment Group, Inc., a corporation organized under the
laws of the  State of  Florida  ("Investment  Group  Inc."),  and  Environmental
Remediation Holding Corporation,  a corporation  organized under the laws of the
State of Colorado (the "Company"),  pursuant to which the Company agreed,  among
other  things:  (i) to issue to  Investment  Group Inc. or its assigns in one or
more  transactions  validly issued,  fully paid, and  nonassessable  shares (the
"Shares")  of common  stock,  par value  $.0001 per share,  of the Company  (the
"Common  Stock")  representing  fifty-one  percent of the issued and outstanding
capital stock of the Company on a fully-diluted basis after giving effect to all
of the transaction  contemplated by the Letter of Intent; and (ii) to enter into
a definitive securities purchase agreement (the "Securities Purchase Agreement")
with  respect to such  issuances  of Common  Stock.  This letter  agreement  (as
amended,   supplemented,   or  otherwise   modified  from  time  to  time,  this
"Agreement),  is intended to set forth the mutual  understanding  and  agreement
between ERHC Investment Group LLC, a limited  liability  company organized under
the  laws  of  the  State  of  Delaware  ("Investor"),  the  assignee  of all of
Investment  Group  Inc.'s  rights  under the Letter of Intent,  and the  Company
regarding  Investor's initial  subscription for a portion of the Shares prior to
the execution and delivery of the Securities  Purchase  Agreement by the parties
thereto.   In   consideration   of   the   respective   agreements,   covenants,
representations,  and  warranties  hereinafter  set  forth  and  other  good and
valuable   consideration,   the  receipt  and   adequacy  of  which  are  hereby
acknowledged,  and  intending to be legally  bound  hereby,  the parties  hereto
hereby agree as follows:

     Investor hereby  irrevocably  subscribes for the portion of the Shares (the
"Initial Shares") representing  twenty-one percent of the issued and outstanding
capital stock of the Company on a fully-diluted basis after giving effect to all
of the transactions contemplated by the Letter of Intent, and Investor shall pay
therefor  in  lawful  money  of the  United  States  of  America  in one or more
installments  from time to time after the date hereof  $210,000 in the aggregate
(the  "Purchase  Price").  The unpaid  amount of the Purchase  Price at any time
outstanding shall bear interest at the  "applicable  federal rate" per annum


<PAGE>



(as such term is used for purposes of ss. 1274(d) of te Internal Revenue Code of
the United  States of America) as in effect on the date hereof.  Upon payment in
full of the Purchase Price and all accrued interest,  the Company shall issue to
Investor  the Initial  Shares,  and shall  deliver or cause to be  delivered  to
Investor a certificate or certificates evidencing such Initial Shares.

     Upon the execution and delivery of the Securities Purchase  Agreement,  the
terms and provisions of the  Securities  Purchase  Agreement  shall apply to the
Initial Shares subscribed for and purchased hereby,  and the other  transactions
contemplated by this Agreement.

     Notwithstanding  anything to the contrary  contained  herein,  if the Final
Closing (as defined in the Letter of Intent) has not occurred within ninety days
after the date hereof,  Investor shall surrender to the Company for cancellation
such rights as it has or such  certificates  as it has received  with respect to
that  number of the  Initial  Shares  such  that,  after  giving  effect to such
surrender,  the remaining  Initial Shares held by Investor would  represent that
percent  of the  issued  and  outstanding  capital  stock  of the  Company  on a
fully-diluted basis after giving effect to all of the transactions  contemplated
by the Letter of Intent based upon a  $5,882,352.90  valuation of the Company as
adjusted by the Prior Action of the Board (as defined in the Letter of Intent).

     As an  inducement  to the  Company to enter into this  Agreement,  Investor
hereby represents and warrants to the Company that:

          (i)  Investor has duly  executed and  delivered  this  agreement,  and
     (assuming  due  execution  and  delivery  by the  Company)  this  agreement
     constitutes a legal, valid and binding obligation of Investor,  enforceable
     against Investor in accordance with its terms;

          (ii) Investor's execution,  delivery and performance hereof do not and
     will not: (A) violate or conflict with Investor's  certificate of formation
     or  similar  organizational  documents,  or any  law or  any  order,  writ,
     judgment, injunction, decree, stipulation,  determination, or award entered
     by or with any  governmental  authority  and  applicable  to Investor;  (B)
     violate or  infringe  upon any rights of any  person;  or (C)  require  any
     consent, approval, authorization or other order of, action by, filing with,
     or notification to, any governmental authority or any other person; and

          (iii)  Investor  understands  that the  Initial  Shares  have not been
     registered under the Securities Act of 1933, as amended, or the laws of any
     state and may not be sold or transferred, or otherwise disposed of, without
     registration under the Securities Act and applicable state securities laws,
     or pursuant to an exemption therefrom.

     As an  inducement  to  Investor to enter into this  Agreement,  the Company
hereby represents and warrants to Investor as follows:

          (i) The Company has duly executed and delivered  this  agreement,  and
     (assuming  due  execution   and  delivery  by  Investor)   this   agreement
     constitutes  a  legal,   valid  and  binding  obligation  of  the  Company,
     enforceable against the Company in accordance with its terms;


<PAGE>



          (ii) The Company's execution,  delivery, and performance hereof do not
     and will not;  (A)  violate or  conflict  with the  Company's  articles  of
     incorporation or by-laws or similar organizational documents, or any law or
     any order, writ, judgment, injunction,  decree, stipulation,  determination
     or award entered by or with any  governmental  authority and  applicable to
     the Company;  (B) violate or infringe upon any rights of any person; or (C)
     require any consent, approval,  authorization or other order of, action by,
     filing with, or notification  to, any  governmental  authority or any other
     person; and

          (iii) Upon issuance,  the Initial Shares will be validly issued, fully
     paid, and nonassessable  and will not be subject to any preemptive  rights,
     and will  represent  not less than  twenty-one  percent  of the  issued and
     outstanding  capital  stock of the Company on a  fully-diluted  basis after
     giving  effect to all of the  transactions  contemplated  by the  Letter of
     Intent.

     No amendment  hereof or supplement  or other  modification  hereto,  and no
consent to, or waiver, discharge, or release of, any term or provision or breach
hereof, shall be valid or effective unless such amendment,  supplement, or other
modification,  or such  consent,  waiver,  discharge,  or release is in writing,
expressly refers hereto, and is signed by the party to be bound thereby.

     If any  term or  other  provision  hereof  is  determined  by any  court of
competent  jurisdiction to be invalid,  illegal, or unenforceable in whole or in
part by reason of any applicable law or public  policy,  and such  determination
becomes final and  nonappealable,  such term or other  provision shall remain in
full force and effect to the  fullest  extent  permitted  by law,  and all other
terms and  provisions  hereof  shall  remain in full  force and  affect in their
entirety.

     This  Agreement  shall be  governed  by,  and  construed  and  enforced  in
accordance with, the laws of the State of New York.

     Each party hereto hereby  unconditionally  and irrevocably waives all right
to trial by jury in any action,  suit, or proceeding (whether based on contract,
tort, or otherwise) based upon,  resulting from,  arising out of, or relating to
this Agreement or any transaction or agreement contemplated hereby.

     This  Agreement  may be executed in any number of  counterparts  and by the
different  parties  hereto in separate  counterparts,  each which when  executed
shall be  deemed  to be an  original,  and all of  which  taken  together  shall
constitute one and the same agreement with the same effect as if such signatures
were upon the same instrument.

     Delivery  of an  executed  counterpart  hereof via  telecopier  shall be as
effective as delivery of an manually executed counterpart hereof.

     Intent.

     No amendment  hereof or supplement  or other  modification  hereto,  and no

     If any  term or  other  provision  hereof  is  determined  by any  court of
competent  jurisdiction to be invalid,  illegal, or unenforceable in whole or in
part by reason of any applicable law or public  policy,  and such  determination
becomes final and  nonappealable,  such term or other  provision shall remain in

this Agreement or any transaction or agreement contemplated hereby.

     This  Agreement  may be executed in any number of  counterparts  and by the
different  parties  hereto in separate  counterparts,  each which when  executed
shall be  deemed  to be an  original,  and all of  which  taken  together  shall
constitute one and the same agreement with the same effect as if such signatures
were upon the same instrument.

     Delivery  of an  executed  counterpart  hereof via  telecopier  shall be as
effective as delivery of an manually executed counterpart hereof.
