ITEM 5. OTHER EVENTS.

     Fleet Capital Corporation - Amended and Restated Loan Agreement

     On October 30, 1998, the Company  entered into an Amended and Restated Loan
and Security  Agreement  (the  "Amended  Credit  Facility")  with Fleet  Capital
Corporation  ("Fleet")  which amended and restated the Credit  Facility  entered
into with Fleet on March 16, 1998.  Reference is made to the  Company's  Current
Report on Form 8-K for March 16,  1998  which  contained  a  description  of the
Credit  Facility.  Under the terms of the Amended Credit  Facility,  any and all
defaults or events of default  which  occurred  under the prior Credit  Facility
were waived.

     Pursuant to the  Amended  Credit  Facility,  the Company is able to borrow,
subject to meeting certain lending  conditions,  a total of approximately  $18.3
million. Of such amount, up to $8.0 million subject to certain limitations, is a
revolving  credit  loan  (the  "Revolving  Credit  Loan"),  $8.25  million  is a
refinancing  of  the  outstanding  term  loan,   approximately   $345,000  is  a
refinancing of  outstanding  equipment  loans,  $490,000 is a refinancing of the
loan used to finance  the Petro  Wireline  Acquisition,  $600,000 is a term loan
advanced on October 30, 1998, the proceeds of which were specified to be used to
repay  suppliers  for goods and  services  and to make  interest  payments on an
outstanding  note of the  Company  in the  amount  of  $3.0  million  issued  in
connection with the acquisition of Diamondback  Drilling Inc. (the  "Diamondback
Note"),  and $600,000 is available to be borrowed subject to the Company meeting
certain  conditions  precedent.  Except for the Revolving Credit Loan, all other
borrowings  (the  "Term  Loan")  are due to be  repaid in  monthly  installments
commencing  November 1, 1998, with all  outstanding  balances due and payable on
March 15, 2001. Interest on the Amended Credit Facility is equal to Fleet's base
rate plus 1.0% on the  Revolving  Line and  Fleet's  base rate plus 1.25% on the
other  borrowings under the Amended Credit  Facility.  To the extent  borrowings
under  the  Revolving  Credit  Loan are less  than the  amount  available  to be
borrowed,  the Company is obligated to pay a commitment fee of 0.5% per month on
the unborrowed amount. In addition,  the Company is obligated to pay a quarterly
collateral  administration  fee of $5,000 and a restructuring fee of $50,000 due
March 31, 1999. Amounts repaid under the Term Loan cannot be reborrowed.

     Among other conditions to the closing under the Amended Credit Facility was
a requirement  that a third party loan $750,000 to the Company,  subordinated to
the  Company's  indebtedness  to  Fleet,  subject  to  certain  exceptions.  The
additional  $600,000  loan by Fleet to the  Company is also  conditioned,  among
other things, on an





                                       2
<PAGE>



additional  $750,000  loan to the Company,  also  subordinated  to the Company's
indebtedness to Fleet, subject to certain exceptions. See St. James Transaction,
below, for a description of the Company's  agreement with SJMB, L.P., whereby it
agreed to make these loans to the Company.

     The Amended  Credit  Facility  terminates  and,  subject to all  prepayment
obligations,  the outstanding  balance is due and payable on March 15, 2001. The
Amended Credit  Facility can be terminated by the Company prior thereto  without
prepayment penalty at any time through April 30, 1999, and thereafter subject to
a prepayment penalty, under certain circumstances,  declining from 2% during the
period May 1, 1999 through March 15, 2000 to 1% during the last year the Amended
Credit  Facility is  outstanding.  The Amended  Credit  Facility is secured by a
senior and prior lien against  substantially all the Company's real and personal
property,  including the assets acquired from Phoenix Drilling  Services,  Inc.,
subject to certain exceptions.

     The Amended Credit  Facility  includes a number of affirmative and negative
covenants  including  requirements  as to  providing  Fleet  with  access to the
Company's  facilities,  financial and other information,  a requirement that St.
James Capital Partners, L.P. and SJMB, LP (collectively "St. James") convert not
less than $4.9  million of  indebtedness  owed by the Company to St.  James into
capital stock of the Company no later than September 30, 1999,  restrictions  on
mergers,  consolidations,   acquisitions,  limitations  on  total  indebtedness,
restrictions  on  liens,  subject  to  certain  exceptions,  on its  properties,
restrictions on  transactions  with  affiliates and  stockholders,  prohibitions
against  the  payment of  dividends  and other  distributions  to  stockholders,
restrictions  on  capital  expenditures,  dispositions  of  assets  and sales of
subsidiary  stock,  among other  covenants.  Such  covenants  also  prohibit the
Company from making payments on the Diamondback Note, except that the Company is
permitted to pay interest  when due,  subject to certain  scheduled  payments of
overdue  interest,  and is  permitted  to make  principal  payments out of funds
derived from the issuance of capital stock or the issuance of subordinated debt.
The Company also is prohibited from making any payment with respect to the $15.4
million owing to St. James,  except that so long as no default  exists under the
Amended  Credit  Facility,  interest  may be paid in kind.  The  Amended  Credit
Facility  contains a number of  affirmative  covenants  requiring the Company to
maintain compliance with various financial matters, including the maintenance of
ratios  of  scheduled   principal   payments  to  adjusted  net  earnings   plus
depreciation  and  amortization  plus interest on subordinated  debt,  ratios of
EBITDA  (as  defined)  to  interest  expense  on  senior  debt,  ratios of total
indebtedness to tangible net worth, and certain levels of adjusted  tangible net
worth,  among other things.  Events of default under the Amended Credit Facility
include,  among other  things,  the failure to



                                       3
<PAGE>



pay principal and interest on the indebtedness under the Amended Credit Facility
when  due,  failure  to  pay  any  other   indebtedness  when  due,  making  any
misrepresentations  to  Fleet  in any  of  the  loan  documents,  breach  of the
covenants  contained  in the  Amended  Credit  Facility  or  defaults  under the
security  documents under the Amended Credit Facility,  defaults under the terms
of other  indebtedness,  adverse changes in the Company's financial condition or
prospects, insolvency and other bankruptcy proceedings, the failure of St. James
to own at least 55% of the Company's issued and outstanding  capital stock (on a
fully diluted basis) prior to a secondary offering of the Company's  securities,
or, pursuant to a secondary public offering of capital stock of the Company,  at
least 30% of the Company's  issued and  outstanding  capital  stock,  on a fully
diluted basis. In the event of a default under the Amended Credit  Facility,  at
the option of Fleet, all amounts  thereunder become  immediately due and payable
and  Fleet  would  have the  right as a  secured  lender  to  foreclose  against
substantially all of the Company's assets. In addition,  under the cross-default
provisions of the Amended Credit Facility, a default under other indebtedness of
the Company could result in a default under the Amended Credit Facility.

     Reference is made to the Amended and Restated  Loan and Security  Agreement
filed as an Exhibit hereto for a complete statement of its terms and conditions.

     St. James Transaction

     On October 30, 1998, the Company entered into an Agreement for Purchase and
Sale (the "Note  Purchase  Agreement")  with  SJMB,  L.P.  ("SJMB"),  a Delaware
limited  partnership  and an  affiliate  of St. James  Capital  Partners,  L.P.,
whereby  SJMB  agreed  to  purchase  and the  Company  agreed to sell up to $2.0
million  principal  amount of a convertible  promissory note (the "Note") due on
March 16, 2001.  Through  October 30, 1998,  the Company  borrowed $1.25 million
under the Note Purchase  Agreement and the balance of $750,000 is intended to be
borrowed.  Payment of principal  and interest on the Note is  collateralized  by
substantially all the assets of the Company, subject, however, to the terms of a
subordination  agreement  between SJMB and Fleet. The Note bears interest at 10%
per annum and is  convertible  into shares of the  Company's  Common  Stock at a
conversion  price of $2.25 per share,  subject to  anti-dilution  adjustment for
certain  issuances  of  securities  by the Company at prices per share of Common
Stock  less  than the  conversion  price  then in  effect,  in which  event  the
conversion price is reduced to the lower price at which such shares were issued.
Pursuant to the Note Purchase Agreement, the Company has agreed to issue to SJMB
for nominal consideration  warrants (the "Warrant") to purchase shares of Common
Stock  exercisable  at a price of $2.25  per  share,  subject  to  anti-dilution
adjustment  for



                                       4
<PAGE>



certain  issuances  of  securities  by the Company at prices per share of Common
Stock less than the exercise  price then in effect,  in which event the exercise
price is reduced to the lower  price at which such  shares  were  issued and the
number of shares issuable is adjusted upward.  St. James will be issued warrants
to purchase 666 shares of Common Stock for each $1,000  borrowed  under the Note
Purchase  Agreement,  or a maximum aggregate of warrants to purchase  1,333,333,
shares.  The shares  issuable  on  conversion  of the Note and  exercise  of the
Warrant have demand and piggy-back  registration rights under the Securities Act
of 1933.  The Note  Purchase  Agreement  grants St. James  certain  preferential
rights  to  provide  future  financings  to  the  Company,  subject  to  certain
exceptions.  The Note  contains  various  affirmative  and  negative  covenants,
including,  among  others,  a  prohibition  against the  Company  consolidating,
merging or entering  into a share  exchange  with another  person,  with certain
exceptions,  without the consent of St. James.  Events of default under the Note
include,  among  other  events,  (i) a default in the  payment of  principal  or
interest on the Note;  (ii) a default in the  performance of any covenant of the
Note Purchase Agreement or other agreement entered into in connection  therewith
and the failure to cure such default;  (iii) any  representation  or warranty of
the Company in the Note Purchase  Agreement or other  agreement  entered into in
connection  therewith  being  untrue in any  material  respect and such  default
remains  uncured;  (iv)  the  Company  defaults  in the  payment  when due or by
acceleration  of any other  indebtedness  having an aggregate  principal  amount
outstanding  in excess of  $100,000  and such  default  remains  uncured;  (v) a
judgment  for the payment of money in excess of $100,000 is entered  against the
Company; (vi) certain bankruptcy or insolvency  proceedings;  (vi) any person or
group of  persons  acquiring  40% or more of the voting  power of the  Company's
outstanding  shares who was not the owner as of October  30,  1998;  and (vii) a
merger of the Company with another  person,  its dissolution or liquidation or a
sale of all or substantially all its assets. A default under the SJMB note would
be a default under the notes issued to St. James Capital Partners,  L.P. in June
and October 1997 and in January 1998. SJMB will receive an origination fee of 2%
of the amount borrowed in connection with the transaction.

<PAGE>

intending to be legally bound,  agree that the Existing Loan Agreement shall, as
of the date hereof, be amended and restated in its entirety, as follows:

SECTION 1. CREDIT FACILITY

         Subject  to the terms  and  conditions  of,  and in  reliance  upon the
representations  and  warranties  made in,  this  Agreement  and the other  Loan
Documents,  Lender  agrees to make a total  credit  facility  of up to  Eighteen
Million  Two  Hundred  Eight-Four   Thousand  Nine  Hundred  Thirty-Six  Dollars
Seventy-Seven  Cents  ($18,284,936.77)  available upon  Borrower's  request,  as
follows:

         1.1      Revolving Credit Loans.

                  1.1.1 Loans and Reserves.  On the date hereof, the outstanding
balance  of  the  Revolving  Credit  Loans  (as  defined  in the  Existing  Loan
Agreement)   made  by  the  Lender  under  the  Existing  Loan  Agreement  shall
automatically, and without any action on the part of any Person, be deemed to be
Revolving  Credit  Loans  hereunder.  Lender  agrees,  during  the  term of this
Agreement  and for so long as no  Default or Event of  Default  exists,  to make
Revolving  Credit Loans to Borrower  from time to time, as requested by Borrower
in the manner  set forth in  Section  3.1.1  hereof,  up to a maximum  principal
amount at any time  outstanding  equal to the Borrowing  Base at such time minus
reserves,  if any.  Lender  shall have the right to  establish  reserves in such
amounts,  and with respect to such  matters,  as Lender shall deem  necessary or
appropriate,  against the amount of Revolving  Credit  Loans which  Borrower may
otherwise request under this Section 1.1.1, including,  without limitation, with
respect to (i) price adjustments, damages, unearned discounts, returned products
or other matters for which credit memoranda are issued in the ordinary course of
Borrower's business;  (ii) other sums chargeable against Borrower's Loan Account
as Revolving  Credit Loans under any section of this  Agreement;  (iii)  amounts
owing by  Borrower  to any Person to the  extent  secured by a Lien other than a
Permitted Lien on, or trust over, any Property of Borrower;  (iv) all amounts of
past due rent or other charges owing at such time by Borrower to any landlord of
any  premises  where any of the  Collateral  is located;  (v) real and  personal
property  taxes  which  are  or  may  become  due  with  respect  to  any of the
Collateral;  and (vi) such other matters, events, conditions or contingencies as
to which Lender,  in its sole credit  judgment,  determines  reserves  should be
established from time to time hereunder.  Borrower hereby  acknowledges that the
aggregate amount of the reserves established by Lender pursuant to Section 1.1.1
which are in effect as of the date of this  Agreement  equals  $500,000 and that
such amount may be  increased  or  decreased by Lender from time to time by such
amounts,  and with respect to such  matters,  as Lender shall deem  necessary or
appropriate.

         1.1.2 Use of Proceeds.  The Revolving Credit Loans shall be used solely
for  Borrower's  general  operating  capital  needs  (including  the  payment of
accounts  payable to trade vendors  incurred for Capital  Expenditures  made for
Equipment  purchased  from such  trade  vendors  prior to the date  hereof) in a
manner  consistent  with the provisions of this Agreement and Applicable Law. In
no event  shall any  proceeds  of any  Revolving  Credit  Loans be used to:  (i)
purchase or to carry, reduce,  retire or refinance any Indebtedness  incurred to
purchase or carry

                                       2

<PAGE>

any margin  stock  (within  the  meaning of  Regulations  G or U of the  Federal
Reserve  Board);   or  (ii)  make  Capital   Expenditures   other  than  Capital
Expenditures  made after the date hereof for Equipment  acquired  after the date
hereof which comply with the first and third sentences of Section 8.2.8 hereof.

         1.2      Term Loans.

                  1.2.1 Term Loan A. On the date hereof, the outstanding balance

amount of Eight  Million  Two  Hundred  Fifty  Thousand  Dollars  and Five Cents
($8,250,000.05)  made by the Lender  under the  Existing  Loan  Agreement  shall
automatically, and without any action on the part of any Person, be deemed to be
Term Loan A hereunder and shall be repayable in accordance with the terms of the
Term A Note and secured by all of the Collateral.  The proceeds of the Term Loan
A shall be used solely for  purposes  for which the  proceeds  of the  Revolving
Credit  Loans are  authorized  to be used.  Borrower may not reborrow any amount
repaid with respect to the Term Loan A.

          1.2.2   Term Loan B. On the date hereof,  the  outstanding  balance of
the Equipment Loans (as defined in the Existing Loan Agreement) in the principal
amount of Three Hundred Forty-Four  Thousand Nine Hundred Thirty-Six Dollars and
Seventy-Two  Cents  ($344,936.72)  held by the Lender  under the  Existing  Loan
Agreement shall automatically, and without any action on the part of any Person,
be deemed to be Term Loan B hereunder and shall be repayable in accordance  with
the terms of the Term B Note and secured by all of the Collateral.  The proceeds

shall be used solely to finance Borrower's purchases of Equipment for use in its
business.  Borrower may not reborrow any amount repaid with respect to Term Loan
B.

          1.2.3   Term Loan C. On the date hereof,  the  outstanding  balance of
the Petro Wireline Term Loan (as defined in the Existing Loan  Agreement) in the
principal  amount of Four  Hundred  Ninety  Thousand  ($490,000.00)  held by the
Lender under the Existing Loan Agreement  shall  automatically,  and without any
action on the part of any  Person,  be deemed  to be Term Loan C  hereunder  and
shall be repayable in  accordance  with the terms of the Term C Note and secured
by all of the  Collateral.  The  proceeds of the Term Loan C, to the extent such
proceeds have not already been used, shall be used solely for the acquisition of
assets of Petro  Wireline.  Borrower  may not  reborrow  any amount  repaid with
respect to Term Loan C.

          1.2.4   Term Loan D.  Lender  agrees  to make a term loan to  Borrower
("Term  Loan D") on the  Closing  Date in the  principal  amount of Six  Hundred
Thousand Dollars ($600,000.00),  which shall be repayable in accordance with the
terms of the Term D Note and  shall be  secured  by all of the  Collateral.  The
proceeds of Term Loan D shall be used to repay Borrower's suppliers for past due
amounts  owed for goods and/or  services,  the  continued  provision of which is
essential to Borrower's ability to carry on its business in the ordinary course,
and to make interest payments of the Diamondback Seller Note pursuant to Section
8.2.15 hereof.  Borrower may not reborrow any amount repaid with respect to Term
Loan D. 3
<PAGE>

          1.2.5 Term Loan E.  Lender  agrees,  so long as no Default or Event of
Default exists, to make a term loan to Borrower ("Term Loan E") in the principal
amount of Six Hundred Thousand Dollars ($600,000.00) immediately upon Borrower's
satisfaction  of all  conditions  precedent  under  Sections 9.1 and 9.2 hereof,
which date  shall be no  earlier  than the  Closing  Date.  Term Loan E shall be
repayable in  accordance  with the terms of the Term E Note and shall be secured
by all of the  Collateral.  The  proceeds  of Term Loan E shall be used to repay
Borrower's  suppliers for past due amounts owed for goods and/or  services,  the
continued  provision of which is essential to Borrower's ability to carry on its
business  in  the  ordinary  course,  and  to  make  interest  payments  of  the
Diamondback  Seller Note  pursuant to Section  8.2.15  hereof.  Borrower may not
reborrow any amount repaid with respect to Term Loan E.

     1.3  Joint and Several Liability; Rights of Contribution.

          (A) Each Borrower states and  acknowledges  that: (i) pursuant
to this Agreement,  Borrowers  desire to utilize their borrowing  potential on a
consolidated basis to the same extent possible if they were merged into a single
corporate  entity and that this Agreement  reflects the  establishment of credit
facilities  which would not  otherwise  be  available  to such  Borrower if each
Borrower  were not  jointly  and  severally  liable  for  payment  of all of the
Obligations;  (ii)  it has  determined  that it will  benefit  specifically  and
materially from the advances of credit contemplated by this Agreement;  (iii) it
is both a condition  precedent  to the  obligations  of Lender  hereunder  and a
desire of the Borrowers  that each  Borrower  execute and deliver to Lender this
Agreement; and (iv) Borrowers have requested and bargained for the structure and
terms of and security for the advances contemplated by this Agreement.

           (B) Each Borrower hereby irrevocably and unconditionally:  (i)
agrees that it is jointly and severally liable to Lender for the full and prompt
payment  of  the  Obligations  and  the  performance  by  each  Borrower  of its
obligations  hereunder in accordance with the terms hereof; (ii) agrees to fully
and  promptly  perform all of its  obligations  hereunder  with  respect to each
advance of credit hereunder as if such advance had been made directly to it; and
(iii)  agrees as a primary  obligation  to  indemnify  Lender on demand  for and
against any loss incurred by Lender as a result of any of the obligations of any
one or more of the Borrowers being or becoming void, voidable,  unenforceable or
ineffective  for any  reason  whatsoever,  whether or not known to Lender or any
Person,  the amount of such loss being the amount which  Lender would  otherwise
have been entitled to recover from any one or more of the Borrowers.

           (C) It is the intent of each Borrower  that the  indebtedness,
obligations and liability hereunder of no one of them be subject to challenge on
any basis, including, without limitation,  pursuant to any applicable fraudulent
conveyance or fraudulent transfer laws. Accordingly,  as of the date hereof, the
liability of each  Borrower  under this Section  1.3,  together  with all of its
other  liabilities to all Persons as of the date hereof and as of any other date
on  which a  transfer  or  conveyance  is  deemed  to occur  by  virtue  of this
Agreement,  calculated in amount  sufficient to pay its probable net liabilities
on its existing  Indebtedness  as the same become  absolute and matured  ("Dated
Liabilities")  is, and is to be, less than the amount of the aggregate of a fair
valuation of its property as of such  corresponding  date ("Dated  Assets").  To
this end, each Borrower  under this Section 1.3, (i) grants to and recognizes in
each other


                                       4
<PAGE>


Borrower,  ratably,  rights of subrogation  and  contribution in the
amount,  if any,  by  which  the  Dated  Assets  of such  Borrower,  but for the
aggregate of subrogation and contribution in its favor recognized herein,  would
exceed  the Dated  Liabilities  of such  Borrower  or, as the case may be,  (ii)
acknowledges receipt of and recognizes its right to subrogation and contribution
ratably  from each of the other  Borrowers  in the amount,  if any, by which the
Dated  Liabilities  of such Borrower,  but for the aggregate of subrogation  and
contribution in its favor  recognized  herein,  would exceed the Dated Assets of
such  Borrower  under this  Section 1.3. In  recognizing  the value of the Dated
Assets  and  the  Dated  Liabilities,  it  is  understood  that  Borrowers  will
recognize,  to at  least  the same  extent  of their  aggregate  recognition  of
liabilities hereunder,  their rights to subrogation and contribution  hereunder.
It is a material  objective  of this Section 1.3 that each  Borrower  recognizes
rights to subrogation and contribution rather than be deemed to be insolvent (or
in contemplation thereof) by reason of an arbitrary  interpretation of its joint
and several obligations  hereunder.  In addition to and not in limitation of the
foregoing  provisions of this Section 1.3, the Borrowers and Lender hereby agree
and  acknowledge  that it is the intent of each  Borrower and of Lender that the
obligations  of each Borrower  hereunder be in all respects in compliance  with,
and not be voidable pursuant to, applicable fraudulent conveyance and fraudulent
transfer laws.

     1.4  Structure  of  Credit   Facility.   Each   Borrower   agrees  and
acknowledges  that the present  structure of the credit  facilities  detailed in
this  Agreement  is  based in part  upon the  financial  and  other  information
presently known to Lender  regarding each Borrower,  the corporate  structure of
Borrowers,  and the present financial condition of each Borrower.  Each Borrower
hereby agrees that Lender shall have the right, in its sole credit judgment,  to
require  that  any or all of the  following  changes  be  made to  these  credit
facilities:  (i) restrict loans and advances between  Borrowers,  (ii) establish
separate  lockbox and dominion  accounts for each Borrower,  (iii) separate Term
Loan A, Term Loan B, Term Loan C, Term Loan D and/or  Term Loan E into  separate
loans to such of the  Borrowers  as  shall be  determined  by  Lender,  and (iv)
establish  such other  procedures as shall be reasonably  deemed by Lender to be
useful in tracking  where Loans are made under this  Agreement and the source of
payments received by Lender on such Loans.

SECTION 2. INTEREST, FEES AND CHARGES

     2.1  Interest.

          2.1.1 Rates of Interest. The outstanding principal amount of the Loans
shall bear interest at the following rates per annum  (individually  called,  as
applicable,  an "Applicable  Annual Rate"): (i) for Revolving Credit Loans, at a
fluctuating rate per annum equal to one percent (1.00%) above the Base Rate, and
(ii) for Term  Loan A, Term Loan B, Term Loan C, Term Loan D and Term Loan E, at
a fluctuating  rate per annum equal to one and one-fourth  percent (1.25%) above
the Base Rate.  The rate of interest  applicable to all Loans shall  increase or
decrease  by an amount  equal to any  increase  or  decrease  in the Base  Rate,
effective  as of the  opening of business on the day that any such change in the
Base Rate occurs.


                                       5
<PAGE>

          2.1.2  Default Rate of Interest.  Upon and after the  occurrence of an
Event of Default,  and during the continuation  thereof, the principal amount of
all Loans shall bear  interest at a rate per annum equal to two percent  (2.00%)
above the  Applicable  Annual  Rate or at such  other  rate per annum  above the
Applicable Rate (not to exceed two percent (2.00%)) as Lender shall, in its sole
discretion, elect (the "Default Rate").

          2.1.3  Maximum Interest. (A) Notwithstanding  anything to the contrary
in this  Agreement  or  otherwise,  (i) if at any time the  amount  of  interest
computed  on the basis of an  Applicable  Annual  Rate or a Default  Rate  would
exceed the amount of such  interest  computed upon the basis of the maximum rate
of interest  permitted by applicable state or federal law in effect from time to
time  hereafter  (the  "Maximum  Legal Rate"),  the interest  payable under this
Agreement  shall be computed upon the basis of the Maximum  Legal Rate,  but any
subsequent  reduction  in such  Applicable  Annual  Rate  or  Default  Rate,  as
applicable,  shall not reduce such interest  thereafter  payable hereunder below
the amount  computed on the basis of the Maximum  Legal Rate until the aggregate
amount of such  interest  accrued and payable  under this  Agreement  equals the
total amount of interest  which would have accrued if such  interest had been at
all times computed  solely on the basis of an Applicable  Annual Rate or Default
Rate,  as  applicable;  and (ii) unless  preempted by federal law, an Applicable
Annual  Rate or  Default  Rate,  as  applicable,  from  time  to time in  effect
hereunder may not exceed the "weekly  ceiling" from time to time in effect under
Chapter  303 of the Texas  Finance  Code  (Vernon's  Texas Code  Annotated),  as
amended  from  time to time (as  amended,  the  "Texas  Finance  Code").  If the
applicable state or federal law is amended in the future to allow a greater rate
of interest to be charged  under this  Agreement  than is  presently  allowed by
applicable state or federal law, then the limitation of interest hereunder shall
be  increased  to the maximum rate of interest  allowed by  applicable  state or
federal law as amended,  which  increase  shall be  effective  hereunder  on the
effective date of such  amendment,  and all interest  charges owing to Lender by
reason thereof shall be payable in accordance with Section 3.2.2 hereof.

          (B)  Excess  Interest.  No  agreements,   conditions,   provisions  or
stipulations  contained in this Agreement or any other  instrument,  document or
agreement between Borrower and Lender or default of Borrower, or the exercise by
Lender of the right to  accelerate  the payment of the maturity of principal and
interest,  or to exercise any option  whatsoever  contained in this Agreement or
any other Loan Document,  or the arising of any  contingency  whatsoever,  shall
entitle  Lender to contract  for,  charge,  or receive,  in any event,  interest
exceeding the Maximum Legal Rate. In no event shall Borrower be obligated to pay
interest  exceeding  such Maximum Legal Rate and all  agreements,  conditions or
stipulations,  if any, which may in any event or contingency  whatsoever operate
to bind,  obligate or compel  Borrower to pay a rate of interest  exceeding  the
Maximum  Legal  Rate,  shall be without  binding  force or effect,  at law or in
equity,  to the extent only of the excess of interest  over such  Maximum  Legal
Rate. In the event any interest is contracted for, charged or received in excess
of the  Maximum  Legal  Rate  ("Excess  Interest"),  Borrower  acknowledges  and
stipulates that any such contract,  charge, or receipt shall be the result of an
accident  and bona fide error,  and that any Excess  received by Lender shall be
applied, first, to reduce the principal then unpaid hereunder; second, to reduce
the other Obligations;  and third,  returned to Borrower, it being the intention
of the  parties  hereto  not to enter at any time into a usurious  or  otherwise
illegal


                                       6
<PAGE>


relationship.  Borrower  recognizes that, with fluctuations in the Base
Rate and the Maximum Legal Rate, such a result could inadvertently occur. By the
execution of this Agreement, Borrower covenants that (i) the credit or return of
any Excess  Interest shall  constitute the acceptance by Borrower of such Excess
Interest,  and (ii) Borrower shall not seek or pursue any other remedy, legal or
equitable,  against  Lender,  based in whole or in part  upon  contracting  for,
charging or  receiving of any  interest in excess of the maximum  authorized  by
applicable  law.  For the  purpose  of  determining  whether  or not any  Excess
Interest has been contracted for, charged or received by Lender, all interest at
any time contracted  for,  charged or received by Lender in connection with this
Agreement  shall be  amortized,  prorated,  allocated  and spread in equal parts
during the entire term of this Agreement.

              (C)  Incorporation  by this  Reference.  The provisions of Section
2.1.3(B) shall be deemed to be incorporated into every document or communication
relating to the Obligations which sets forth or prescribes any account, right or
claim or alleged account,  right or claim of Lender with respect to Borrower (or
any other  obligor in respect of  Obligations),  whether or not any provision of
Section 2.1.3(B) is referred to therein.  All such documents and  communications
and all figures set forth therein  shall,  for the sole purpose of computing the
extent of the Obligations of Borrower (or any other obligor)  asserted by Lender
thereunder, be automatically re-computed by Borrower or any such obligor, and by
any court  considering  the same, to give effect to the  adjustments  or credits
required by Section 2.1.3(B).

          2.2  Computation of Interest and Fees.  Interest and  commitment  fees
hereunder  shall be calculated  daily and shall be computed on the actual number
of days elapsed over a year of 360 days.  For the purpose of computing  interest
hereunder,  all items of payment  received by Lender shall be deemed  applied by
Lender on account of the  Obligations  (subject to final  payment of such items)
one (1) Business Day after  receipt by Lender of such items in Lender's  account
located in Providence, Rhode Island, and Lender shall be deemed to have received
such items of payment on the date specified in Section 3.4 hereof.

          2.3  Restructuring  Fee.  Borrower shall pay to Lender a restructuring
fee of Fifty Thousand Dollars ($50,000), which shall be fully earned and (except
to the extent  otherwise  required by Applicable Law)  nonrefundable on the date
hereof, and shall be payable on March 31, 1999.

          2.4  Commitment  Fee.  Borrower  shall pay to Lender a commitment  fee
equal to one-half  percent  (0.50%) per annum of the amount by which the Average
Monthly  Revolving  Credit Loan Balance is less than the Total Revolving  Credit
Facility.  The commitment fee shall be payable monthly,  in arrears, on the last
day of each calendar month hereafter.

          2.5  Collateral  Administration  Fee.  Borrower  shall pay to Lender a
quarterly collateral administration fee of Five Thousand Dollars ($5,000), which
fee shall be paid to Lender on each July 1,  October  1,  January 1, and April 1
thereafter during the term hereof.

          2.6 Audit and Appraisal Fees.  Borrower shall reimburse Lender for all
reasonable  out-of-pocket  costs and expenses  incurred by Lender in  connection
with  audits and  appraisals  of


                                       7
<PAGE>


Borrower's  books and  records  and such  other  matters  as Lender  shall  deem
appropriate. All such out-of-pocket expenses shall be payable on demand.

          2.7 Reimbursement of Expenses. If, at any time or times, regardless of
whether or not an Event of Default then exists, Lender or any Participant incurs
legal or  accounting  expenses or any other costs or  out-of-pocket  expenses in
connection  with (i) the negotiation and preparation of this Agreement or any of
the other Loan Documents,  any amendment of or modification of this Agreement or
any of the other Loan  Documents,  or any sale or attempted sale of any interest
herein to any other Person;  (ii) the administration of this Agreement or any of
the other Loan Documents and the transactions  contemplated  hereby and thereby;
(iii) any  litigation,  contest,  dispute,  suit,  proceeding or action (whether
instituted  by Lender,  Borrower or any other Person) in any way relating to the
Collateral,  this  Agreement or any of the other Loan  Documents  or  Borrower's
affairs;  (iv) any  attempt to enforce  any rights of Lender or any  Participant
against  Borrower or any other Person which may be obligated to Lender by virtue
of this  Agreement  or any of the other Loan  Documents,  including  the Account
Debtors;  or (v) any attempt to inspect,  verify,  protect,  preserve,  restore,
collect, sell, liquidate or otherwise dispose of or realize upon the Collateral;
then all such  legal  and  accounting  expenses,  other  costs and out of pocket
expenses  of Lender  shall be charged to  Borrower.  All amounts  chargeable  to
Borrower  under  this  Section  2.7 shall be  Obligations  secured by all of the
Collateral,  shall be payable on demand to Lender or to such Participant, as the
case may be, and shall  bear  interest  from the date such  demand is made until
paid in full at the rate applicable to Revolving Credit Loans from time to time.
Borrower  shall also  reimburse  Lender for  expenses  incurred by Lender in its
administration  of the  Collateral  to the extent and in the manner  provided in
Section 6 hereof.

          2.8 Bank Charges. Borrower shall pay to Lender, on demand, any and all
normal and customary  fees,  costs or expenses  which Lender or any  Participant
pays to a bank or other similar  institution  (including any fees paid by Lender
to any  Participant)  arising out of or in connection with (i) the forwarding to
Borrower  or  any  other  Person  on  behalf  of  Borrower,  by  Lender  or  any
Participant,  of proceeds  of loans made by Lender to Borrower  pursuant to this
Agreement and (ii) the depositing for collection,  by Lender or any Participant,
of any  check  or item  of  payment  received  or  delivered  to  Lender  or any
Participant on account of the Obligations.

SECTION 3. LOAN ADMINISTRATION

          3.1 Manner of Borrowing  Revolving Credit Loans.  Borrowings under the
credit facility established pursuant to Section 1 hereof shall be as follows:

              3.1.1 Loan Requests.  A request for a Revolving  Credit Loan, Term
Loan C, Term Loan D or Term Loan E shall be made, or shall be deemed to be made,
in the following manner:  (i) Borrower shall give Lender notice of its intention
to borrow,  in which notice  Borrower  shall  specify the amount of the proposed
borrowing  and the proposed  borrowing  date,  no later than 11:00 a.m.  Dallas,
Texas time on the proposed borrowing date; provided,  however, Lender shall have
the  right to refuse to  accept  such a  request  or refuse to make a  Revolving
Credit Loan if at such time there  exists a Default or an Event of Default;  and
(ii) the  becoming due of any amount  required to be paid under this  Agreement,
under Term Notes or under any of


                                       8
<PAGE>


the other Loan Documents,  whether as principal, accrued interest, fees or other
charges, shall be deemed irrevocably to be a request by Borrower to Lender for a
Revolving Credit Loan on the due date of, and in an aggregate amount required to
pay, such principal,  accrued interest,  fees or other charges, and the proceeds
of any such  Revolving  Credit Loan may be  disbursed by Lender by way of direct
payment of the relevant Obligation (whether or not any Default, Event of Default
or  Out-of-Formula  Condition  exists at the time of or would  result  from such
Revolving  Credit  Loan)  and  shall  bear  interest  at the  rate  of  interest
applicable to Revolving Credit Loans. As an  accommodation  to Borrower,  Lender
may  permit  telephonic  requests  for  loans  and  electronic   transmittal  of
instructions,  authorizations,  agreements  or  reports  to Lender by  Borrower.
Unless Borrower specifically directs Lender in writing not to accept or act upon
telephonic  or electronic  communications  from  Borrower,  Lender shall have no
liability to Borrower for any loss or damage suffered by Borrower as a result of
Lender's honoring of any requests, execution of any instructions, authorizations
or agreements or reliance on any reports  communicated to Lender  telephonically
or  electronically  and purporting to have been sent to Lender by any individual
from time to time  designated  by Borrower as an  authorized  officer and Lender
shall  have  no  duty  to  verify  the  origin  or   authenticity  of  any  such
communication.

              3.1.2 Disbursement.  Borrower hereby irrevocably authorizes Lender
to disburse the proceeds of each Revolving  Credit Loan requested,  or deemed to
be  requested,  pursuant to this Section  3.1.2 as follows:  (i) the proceeds of
each Revolving  Credit Loan requested under Section  3.1.1(i) shall be disbursed
by  Lender in lawful  money of the  United  States  of  America  in  immediately
available  funds, in the case of the initial  borrowing,  in accordance with the
terms of the written disbursement letter from Borrower,  and in the case of each
subsequent  borrowing,  by wire  transfer to such bank  account as may be agreed
upon by  Borrower  and Lender  from time to time or  elsewhere  if pursuant to a
written direction from Borrower;  and (ii) the proceeds of each Revolving Credit
Loan requested  under Section  3.1.1(ii)  shall be disbursed by Lender by way of
direct payment of the relevant interest or other Obligation.

              3.1.3  Authorization.   Borrower  hereby  irrevocably   authorizes
Lender,  in Lender's sole discretion,  to advance to Borrower,  and to charge to
Borrower's Loan Account  hereunder as a Revolving  Credit Loan, a sum sufficient
to pay all interest accrued on the Obligations during the immediately  preceding
month and to pay all costs,  fees and  expenses  at any time owed by Borrower to
Lender hereunder.

          3.2  Payments.  All payments  with  respect to any of the  Obligations
shall be made to  Lender on the date when due,  in  Dollars  and in  immediately
available funds,  without any offset or counterclaim.  Except where evidenced by
notes or other  instruments  issued or made by Borrower  to Lender  specifically
containing  payment  provisions  which are in conflict with this Section 3.2 (in
which event the conflicting  provisions of said notes or other instruments shall
govern and control), the Obligations shall be payable as follows:

              3.2.1 Principal.  Principal payable on account of Revolving Credit
Loans shall be payable by Borrower to Lender  immediately  upon the  earliest of
(i) except as otherwise provided in Section 3.3 hereof, the receipt by Lender or
Borrower  of any  proceeds  of any of the  Collateral,  to the  extent  of  said
proceeds,  (ii) the  occurrence of an Event of Default in


                                       9
<PAGE>


consequence of which Lender elects to accelerate the maturity and payment of the
Obligations,  or (iii)  termination  of this  Agreement  pursuant  to  Section 4
hereof;  provided,  however, that if an Out-of-Formula  Condition shall exist at
any time,  Borrower  shall,  on  demand,  repay the  Obligations  to the  extent
necessary to eliminate the Out-of-Formula Condition.

              3.2.2  Interest.  Interest  accrued on the Revolving  Credit Loans
shall be due on the  earliest of (i) the first  calendar  day of each month (for
the immediately preceding month),  computed through the last calendar day of the
preceding  month,  (ii) the  occurrence of an Event of Default in consequence of
which Lender elects to accelerate the maturity and payment of the Obligations or
(iii) termination of this Agreement pursuant to Section 4 hereof.

              3.2.3 Costs,  Fees and Charges.  Costs,  fees and charges  payable
pursuant to this Agreement  shall be payable by Borrower as and when provided in
Section 2 hereof,  to Lender  or to any  other  Person  designated  by Lender in
writing.

              3.2.4 Other Obligations.  The balance of the Obligations requiring
the payment of money, if any, shall be payable by Borrower to Lender as and when
provided in this Agreement,  the Other Agreements or the Security Documents, or,
if no date of payment is otherwise specified in the Loan Documents, on demand.

          3.3 Mandatory  Prepayments;  Proceeds of Sale,  Loss,  Destruction  or
Condemnation  of  Collateral.  If Borrower  sells any of the  Equipment  or real
Property,  or if any of  the  Collateral  is  lost  or  destroyed  or  taken  by
condemnation,  Borrower shall pay to Lender,  unless otherwise agreed by Lender,
as and when received by Borrower and as a mandatory prepayment of the Loans (or,
at Lender's  option,  such of the other  Obligations as Lender may elect), a sum
equal to the net proceeds  (including  insurance  payments) received by Borrower
from such sale,  loss,  destruction or condemnation  (other than (i) proceeds of
the  disposition  of Equipment  otherwise  permitted  under Section 6.4.2 hereof
which is replaced in accordance with Section 6.4.2 hereof,  and (ii) proceeds of
insurance  claims or  customer  reimbursements  for lost,  damaged or  destroyed
Equipment  when such  proceeds are used by Borrower to replace such  Equipment),
and applied as follows:  (i) first to accrued but unpaid  interest  owing on the
Loans; (ii) then to outstanding  amounts under Term Loan A up to the full amount
thereof;  (iii)  then to  outstanding  amounts  under Term Loan B up to the full
amount  thereof;  (iv) then to  outstanding  amounts under Term Loan C up to the
full amount thereof; (v) then to outstanding amounts under Term Loan D up to the
full amount  thereof;  (vi) then to outstanding  amounts under Term Loan E up to
the full  amount  thereof;  and  (vii)  then to  outstanding  amounts  under the
Revolving  Credit Loans up to the full amount  thereof.  Nothing in this Section
3.3 shall  authorize  Borrower to sell any of the  Collateral  without  Lender's
prior written consent except as otherwise  expressly  provided elsewhere in this
Agreement.

          3.4  Application  of Payments  and  Collections.  All items of payment
received by Lender by 1:00 p.m., Providence,  Rhode Island time, on any Business
Day shall be deemed received on that Business Day. All items of payment received
after 1:00 p.m.,  Providence,  Rhode Island  time,  on any Business Day shall be
deemed received on the following  Business Day. Borrower  irrevocably waives the
right to direct the  application of any and all payments and


                                       10
<PAGE>


collections at any time or times hereafter  received by Lender from or on behalf
of Borrower,  and Borrower does hereby  irrevocably agree that Lender shall have
the  continuing  exclusive  right to apply and reapply any and all such payments
and  collections  received at any time or times hereafter by Lender or its agent
against  the  Obligations,   in  such  manner  as  Lender  may  deem  advisable,
notwithstanding any entry by Lender upon any of its books and records. If as the
result of collections of Accounts as authorized by Section 6.2.6 hereof a credit
balance  exists in the Loan  Account,  such  credit  balance  shall  not  accrue
interest in favor of Borrower, but shall be available to Borrower at any time or
times for so long as no Default or Event of Default exists.  Such credit balance
shall not be applied or be deemed to have been  applied as a  prepayment  of the
Term Loan,  except that Lender  may, at its option,  offset such credit  balance
against  any of the  Obligations  upon and after the  occurrence  of an Event of
Default.

          3.5 All Loans to Constitute One Obligation. All Loans shall constitute
one general  Obligation of Borrower,  and shall be secured by Lender's  security
interest  and  Lien  upon  all of the  Collateral,  and  by all  other  security
interests and Liens heretofore, now or at any time or times hereafter granted by
Borrower to Lender.

          3.6 Loan Account  Lender shall  establish an account on its books (the
"Loan  Account")  and shall  enter all Loans as debits to the Loan  Account  and
shall also  record in the Loan  Account  all  payments  made by  Borrower on any
Obligations and all proceeds of Collateral which are finally paid to Lender, and
may record therein,  in accordance  with customary  accounting  practice,  other
debits and credits,  including  interest  and all charges and expenses  properly
chargeable to Borrower.

          3.7  Statements  of Account.  Lender will account to Borrower  monthly
with a statement of Loans, charges and payments made pursuant to this Agreement,
and  such  account  rendered  by  Lender  shall be  deemed  final,  binding  and
conclusive upon Borrower unless Lender is notified by Borrower in writing to the
contrary  within  thirty (30) days after the date each  accounting  is deemed to
have been sent pursuant to Section 11.8 hereof. Such notice shall only be deemed
an objection to those items specifically objected to therein.

SECTION 4.    TERM AND TERMINATION

          4.1 Term of  Agreement.  Subject  to Section  4.2 hereof and  Lender's
right to cease  making  Loans to Borrower  upon or after the  occurrence  of any
Default  or Event of  Default,  this  Agreement  shall be in effect for a period
commencing  on the date  hereof  and  ending  on March 15,  2001 (the  "Original
Term").

          4.2 Termination.

              4.2.1  Termination by Lender.  Lender may terminate this Agreement
without  notice as of the last day of the Original  Term and at any time without
notice upon or after the occurrence of an Event of Default.

              4.2.2 Termination by Borrower. Upon (i) at least fifteen (15) days
prior written  notice to Lender in the event of a termination  resulting  from a
secondary public offering  permitted  hereunder or (ii) at least sixty (60) days
prior written notice to Lender in all other circumstances,  Borrower may, at its
option, terminate this Agreement;  provided,  however, no such termination shall
be effective  until  Borrower  has paid all of the  Obligations  in  immediately
available  funds.  Any  notice  of  termination   given  by  Borrower  shall  be
irrevocable unless Lender otherwise agrees in writing,  and Lender shall have no
obligation  to make any Loans on or after the  termination  date  stated in such
notice.  Borrower may elect to terminate this Agreement in its entirety only. No
section of this Agreement or type of Loan available  hereunder may be terminated
singly.

              4.2.3 Termination Charges. On the effective date of termination of
this Agreement for any reason,  Borrower shall pay to Lender (in addition to the
then outstanding  principal,  accrued interest and other charges owing under the
terms of this  Agreement  and any of the other  Loan  Documents)  as  liquidated
damages for the loss of the bargain  and not as a penalty,  an amount  equal to:
(i) nothing (-0-) if  termination  occurs during the period from the date hereof
through and  including  the date which is six months from the date hereof;  (ii)
two percent (2.0%) of the Total Credit Facility if termination occurs during the
period  from  the  date  which is six  months  and one day from the date  hereof
through and including  March 15, 2000; and (iii) one percent (1.0%) of the Total
Credit  Facility  if  termination  occurs  during the period from March 16, 2000
through and including March 14, 2001; provided,  however,  that in the event the
Total Credit Facility is prepaid solely from the proceeds of a secondary  public
offering of capital  stock (or other  securities  acceptable to Lender) of Black
Warrior,  Borrower  shall pay to Lender an amount equal to one percent (1.0%) of
the then  outstanding  principal  balance of the Total  Credit  Facility if such
secondary  public offering closes during the period from the date hereof through
and including  September 15, 1999, and no termination charge shall be payable if
such secondary  public  offering closes after September 15, 1999. If termination
occurs on the last day of the  Original  Term,  no  termination  charge shall be
payable.

              4.2.4  Effect  of  Termination.  All of the  Obligations  shall be
immediately  due and payable upon the  termination  date stated in any notice of
termination  of  this  Agreement.  All  undertakings,   agreements,   covenants,
warranties and representations of Borrower contained in the Loan Documents shall
survive any such termination and Lender shall retain its Liens in the Collateral
and all of its rights and remedies under the Loan Documents notwithstanding such
termination  until  Borrower has paid the  Obligations  to Lender,  in full,  in
immediately available funds, together with the applicable termination charge, if
any. Notwithstanding the payment in full of the Obligations, Lender shall not be
required to terminate  its security  interests in the  Collateral  unless,  with
respect to any loss or damage Lender may incur as a result of dishonored  checks
or other items of payment received by Lender from Borrower or any Account Debtor
and applied to the Obligations, Lender shall, at its option, (i) have received a
written  agreement,  executed by Borrower and by any Person whose loans or other
advances  to Borrower  are used in whole or in part to satisfy  the  Obligations
(provided,  however,  that such  agreement  shall not be  required by any Person
other than Borrower in the event of a secondary public offering of capital stock
of  Borrower),  indemnifying  Lender from any such loss or damage;  or (ii) have
retained




                                       12
<PAGE>

such monetary  reserves and Liens on the  Collateral  for such period of time as
Lender,  in its  discretion,  may deem necessary to protect Lender from any such
loss or damage.

SECTION 5.  SECURITY INTERESTS

          5.1 Security Interest in Collateral.  To secure the prompt payment and
performance  to  Lender of all of the  Obligations,  Borrower  hereby  grants to
Lender a continuing  security  interest and Lien upon all of Borrower's  assets,
including all of the  following  Property and interests in Property of Borrower,
whether  now owned or  existing or  hereafter  created,  acquired or arising and
wheresoever located:

              (i)   All Accounts;

              (ii)  All Inventory;

              (iii) All Equipment;

              (iv)  All General Intangibles;

              (v)   All investment property (as defined in Section  9.115 of the
Code);

              (vi)  All real Property;

              (vii) All monies and other Property of any kind now or at any time
or times  hereafter in the possession or under the control of Lender or a bailee
or Affiliate of Lender;

              (viii) All accessions to,  substitutions for and all replacements,
products and cash and non-cash  proceeds of (i) through (vii) above,  including,
without limitation,  proceeds of and unearned premiums with respect to insurance
policies insuring any of the Collateral; and

              (ix)  All  books  and  records  (including,   without  limitation,
customer lists, credit files, computer programs,  print-outs, and other computer
materials  and  records) of  Borrower  pertaining  to any of (i) through  (viii)
above.

          5.2 Lien Perfection;  Further Assurances. To the extent not previously
executed  under the Existing Loan  Agreement,  Borrower shall execute such UCC-1
financing  statements  as are  required by the Code and such other  instruments,
assignments  or documents as are necessary to perfect  Lender's Lien upon any of
the Collateral and shall take such other action as may be required to perfect or
to  continue  the  perfection  of  Lender's  Lien  upon the  Collateral.  Unless
prohibited by Applicable Law,  Borrower hereby  authorizes Lender to execute and
file any such financing statement on Borrower's behalf. The parties agree that a
carbon, photographic or other reproduction of this Agreement shall be sufficient
as a  financing  statement  and may be filed in any  appropriate  office in lieu
thereof.  At Lender's request,  Borrower shall also promptly execute or cause to
be executed and shall deliver to Lender any and all documents,  instruments  and



                                       13
<PAGE>

agreements  deemed  necessary by Lender to give effect to or carry out the terms
or intent of the Loan Documents.

          5.3 Lien on Realty.  The due and punctual  payment and  performance of
the Obligations  shall also be secured by the Lien created by each Mortgage upon
all real Property of Borrower  described  therein.  To the extent not previously
executed under the Existing Loan  Agreement,  each Mortgage shall be executed by
Borrower in favor of Lender and shall be duly recorded,  at Borrower's  expense,
in each office where such recording is required to constitute a fully  perfected
Lien  on the  real  Property  covered  thereby.  To the  extent  not  previously
delivered under the Existing Loan  Agreement,  Borrower shall deliver to Lender,
at Borrower's  expense,  mortgagee  title  insurance  policies issued by a title
insurance  company  satisfactory to Lender,  which policies shall be in form and
substance satisfactory to Lender and shall insure a valid first Lien in favor of
Lender  on the  Property  covered  thereby,  subject  only to  those  exceptions
reasonably  acceptable  to Lender and its  counsel.  Borrower  shall  deliver to
Lender such other  documents,  including,  without  limitation,  as-built survey
prints of the real Property,  as Lender and its counsel may request  relating to
the real Property subject to each Mortgage.

SECTION 6. COLLATERAL ADMINISTRATION

          6.1 General

              6.1.1  Location of  Collateral.  All tangible items of Collateral,
other than Inventory in transit,  such Equipment in transit as may be reasonably
necessary  to perform work at locations  other than the business  locations  set
forth on Exhibit B hereto,  and only for long as may be reasonably  necessary to
complete such work,  motor vehicles and  investment  property held in an account
with a securities  intermediary,  shall at all times be kept by Borrower and its
Subsidiaries  at one or more of the  business  locations  set forth on Exhibit B
hereto and shall not,  without the prior  written  approval of Lender,  be moved
therefrom except, prior to an Event of Default and Lender's  acceleration of the
maturity of the Obligations in consequence  thereof,  for (i) sales of Inventory
in the  ordinary  course of  business;  and (ii)  removals  in  connection  with
dispositions of Equipment that are authorized by Section 6.4.2 hereof.

              6.1.2 Insurance of Collateral. Borrower shall maintain and pay for
insurance  upon all Collateral  wherever  located and with respect to Borrower's
business,  covering casualty,  hazard,  public liability and such other risks in
such amounts and with such insurance companies as are reasonably satisfactory to
Lender.  Borrower  shall  deliver  the  originals  or  certified  copies of such
policies to Lender with satisfactory lender's loss payable  endorsements,  which
policies shall name Lender as sole loss payee,  assignee or additional  insured,
as appropriate.  Each policy of insurance or endorsement  shall contain a clause
requiring  the  insurer to give not less than  thirty  (30) days  prior  written
notice to  Lender in the event of  cancellation  of the  policy  for any  reason
whatsoever  and a clause  specifying  that the  interest of Lender  shall not be
impaired  or  invalidated  by any act or neglect of Borrower or the owner of the
Property or by the  occupation of the premises for purposes more  hazardous than
are  permitted  by said  policy.  If Borrower  fails to provide and pay for such
insurance,  Lender may, at its option, but shall not be required to,


                                       14
<PAGE>

procure the same and charge  Borrower  therefor.  Borrower  agrees to deliver to
Lender,  promptly as rendered,  true copies of all reports made in any reporting
forms to insurance companies.

              6.1.3  Protection  of  Collateral.  All  expenses  of  protecting,
storing,   warehousing,   insuring,  handling,   maintaining  and  shipping  the
Collateral,  any and all excise,  property,  sales, and use taxes imposed by any
Applicable Law on any of the  Collateral or in respect of the sale thereof,  and
all other  payments  required to be made by Lender to any Person to realize upon
any  Collateral  shall  be borne  and paid by  Borrower.  If  Borrower  fails to
promptly pay any portion thereof when due, Lender may, at its option,  but shall
not be required to, pay the same and charge Borrower therefor.  Lender shall not
be liable or responsible in any way for the safekeeping of any of the Collateral
or for any loss or damage  thereto  (except for  reasonable  care in the custody
thereof  while any  Collateral  is in  Lender's  actual  possession)  or for any
diminution in the value thereof,  or for any act or default of any warehouseman,
carrier, forwarding agency, or other Person whomsoever, but the same shall be at
Borrower's sole risk.

          6.2 Administration of Accounts.

              6.2.1 Records,  Schedules and  Assignments  of Accounts.  Borrower
shall keep  accurate and  complete  records of its Accounts and all payments and
collections  thereon and shall submit to Lender on such periodic basis as Lender
shall request a sales and collections  report for the preceding  period, in form
satisfactory to Lender. On or before the twentieth (20th) day of each month from
and after the date hereof,  Borrower shall deliver to Lender, in form acceptable
to Lender, a detailed aged trial balance of all Accounts existing as of the last
day of the preceding month, specifying the names,  addresses,  face value, dates
of invoices  and due dates for each  Account  Debtor  obligated on an Account so
listed ("Schedule of Accounts"),  and, upon Lender's request therefor, copies of
proof of delivery and the original  copy of all  documents,  including,  without
limitation,  repayment  histories  and present  status  reports  relating to the
Accounts so scheduled  and such other  matters and  information  relating to the
status  of then  existing  Accounts  as  Lender  shall  reasonably  request.  In
addition,  if Accounts  in an  aggregate  face  amount in excess of  Twenty-Five
Thousand Dollars ($25,000) become ineligible because they fall within one of the
specified  categories of  ineligibility  set forth in the definition of Eligible
Accounts or otherwise  established  by Lender,  Borrower  shall notify Lender of
such  occurrence on the first  Business Day  following  the day such  occurrence
becomes known to Borrower and the Borrowing Base shall  thereupon be adjusted to
reflect such  occurrence.  If requested by Lender,  Borrower  shall  execute and
deliver to Lender agings and formal  written  assignments of all of its Accounts
weekly or daily,  which shall  include all Accounts that have been created since
the date of the last  assignment,  together  with  copies of invoices or invoice
registers related thereto.

                  6.2.2 Discounts,  Allowances, Disputes. If Borrower grants any
discounts,  allowances  or credits that are not shown on the face of the invoice
for the Account  involved,  Borrower shall report such discounts,  allowances or
credits,  as the case may be, to Lender as part of the next required Schedule of
Accounts. If any amounts due and owing in excess of Twenty-Five Thousand Dollars
($25,000) are in dispute between Borrower and any Account Debtor, Borrower shall
provide Lender with written notice thereof at the time of submission of the next


                                       15
<PAGE>


Schedule  of  Accounts,  explaining  in detail the reason for the  dispute,  all
claims  related  thereto  and the  amount  in  controversy.  Upon and  after the
occurrence  of an Event of  Default,  Lender  shall  have the right to settle or
adjust  all  disputes  and  claims  directly  with  the  Account  Debtor  and to
compromise  the amount or extend the time for payment of the Accounts  upon such
terms  and  conditions  as  Lender  may  deem  advisable,   and  to  charge  the
deficiencies,   costs  and  expenses  thereof,  including  attorney's  fees,  to
Borrower.

              6.2.3 Taxes.  If an Account  includes a charge for any tax payable
to any  governmental  taxing  authority,  Lender  is  authorized,  in  its  sole
discretion,  to pay the amount  thereof to the proper  taxing  authority for the
account of Borrower and to charge Borrower  therefor;  provided,  however,  that
Lender  shall  not be  liable  for any  such  taxes to any  governmental  taxing
authority that may be due by Borrower.

              6.2.4 Account  Verification.  Whether or not a Default or an Event
of Default has  occurred,  any of Lender's  officers,  employees or agents shall
have the  right,  at any time or times  hereafter,  in the name of  Lender,  any
designee  of Lender or  Borrower,  to verify the  validity,  amount or any other
matter relating to any Accounts by mail,  telephone,  facsimile  transmission or
otherwise. Borrower shall cooperate fully with Lender in an effort to facilitate
and promptly conclude any such verification process.

              6.2.5 Maintenance of Dominion  Account.  Borrower shall maintain a
Dominion  Account  pursuant to a lockbox  arrangement  acceptable to Lender with
such banks as may be selected by Borrower and be acceptable to Lender.  Borrower
shall issue to any such banks an  irrevocable  letter of  instruction  directing
such banks to deposit all payments or other remittances  received in the lockbox
to the Dominion Account for application on account of the Obligations. All funds
deposited  in the  Dominion  Account  shall  immediately  become the property of
Lender and Borrower  shall obtain the agreement by such banks in favor of Lender
to waive any offset rights against the funds so deposited.

              6.2.6 Collection of Accounts,  Proceeds of Collateral. To expedite
collection,  Borrower shall endeavor in the first instance to make collection of
its  Accounts  for Lender.  All  remittances  received by Borrower in respect of
Accounts,  together with the proceeds of any other Collateral,  shall be held as
Lender's  property  by  Borrower  as trustee of an  express  trust for  Lender's
benefit and  Borrower  shall  immediately  deposit  same in kind in the Dominion
Account. Lender retains the right at all times after the occurrence of a Default
or an Event of  Default  to  notify  Account  Debtors  that  Accounts  have been
assigned  to Lender  and to  collect  Accounts  directly  in its own name and to
charge the collection costs and expenses,  including reasonable  attorneys' fees
to Borrower.

          6.3  Administration  of  Inventory.  Except in the ordinary  course of
business,  Borrower  shall keep accurate and complete  records of its Inventory.
Borrower shall not return any of its Inventory to a supplier or vendor  thereof,
or to any other Person,  whether for cash,  credit against  future  purchases or
then existing payables, or otherwise without prior written approval from Lender.


                                       16
<PAGE>

          6.4 Administration of Equipment.

              6.4.1  Records and  Schedules of  Equipment.  Borrower  shall keep
accurate records itemizing and describing the kind, type, quality,  quantity and
value of its Equipment  and all  dispositions  made in  accordance  with Section
6.4.2 hereof,  and shall furnish Lender with a current  schedule  containing the
foregoing information on at least an annual basis and more often if requested by
Lender.  Immediately  on request  therefor by Lender,  Borrower shall deliver to
Lender any and all evidence of ownership, if any, of any of the Equipment.

              6.4.2 Dispositions of Equipment.  Borrower will not sell, lease or
otherwise  dispose of or transfer  any of the  Equipment  on which  Lender has a
first Lien or any part  thereof  without  the prior  written  consent of Lender;
provided,  however,  that the foregoing restriction shall not apply, for so long
as no Default or Event of  Default  exists,  to (i)  dispositions  of  Equipment
which, in the aggregate during any consecutive  twelve-month  period, has a fair
market value or book value,  whichever is less,  of Two Hundred  Fifty  Thousand
Dollars  ($250,000) or less,  provided that all proceeds thereof are remitted to
Lender for application to the Loans,  or (ii)  replacements of Equipment that is
substantially  worn,  damaged or obsolete with Equipment of like kind,  function
and value, provided that the replacement Equipment shall be acquired prior to or
concurrently  with any disposition of the Equipment that is to be replaced,  the
replacement  Equipment  shall be free and clear of Liens  other  than  Permitted
Liens that are not Purchase Money Liens, and Borrower shall have given Lender at
least five (5) days' prior written notice of such disposition.

              6.4.3 Condition of Equipment.  Borrower represents and warrants to
Lender that the Equipment is in good  operating  condition  and repair,  and all
necessary  replacements  of and repairs  thereto shall be made so that the value
and operating  efficiency of the Equipment  shall be maintained  and  preserved,
reasonable wear and tear excepted. Borrower will not permit any of the Equipment
to become  affixed to any real  Property  leased to Borrower so that an interest
arises therein under the real estate laws of the applicable  jurisdiction unless
the landlord of such real  Property has executed a landlord  waiver or leasehold
mortgage  in  favor  of and in  form  acceptable  to  Lender,  or,  at  Lender's
discretion, a reserve for rent, acceptable to Lender, has been established,  and
Borrower  will not permit any of the  Equipment  to become an  accession  to any
personal Property that is subject to a Lien unless the Lien is a Permitted Lien.

          6.5  Payment of  Charges.  All amounts  chargeable  to Borrower  under
Section 6 hereof shall be Obligations secured by all of the Collateral, shall be
payable on demand and shall bear  interest  from the date such  advance was made
until paid in full at the rate applicable to Revolving Credit Loans from time to
time.

SECTION 7.   REPRESENTATIONS AND WARRANTIES

require,  the creation or  imposition of any Lien (other than  Permitted  Liens)

Borrower or any of its Subsidiaries.

              7.1.3 Legally Enforceable  Agreement.  This Agreement is, and each
of the other Loan  Documents  when  delivered  under this  Agreement  will be, a
legal,  valid and binding  obligation  of each of Borrower and its  Subsidiaries

extent that such enforcement may be limited by applicable bankruptcy, insolvency

seller thereof, or through Borrower's  acquisitions of Dynajet,  Inc., Petrolog,
Inc.,  Production  Well  Services,  Inc.,  Diamondback  Directional,  Inc.,  Cam
Wireline,   Inc.,   Phoenix  or  Petro  Wireline  within  the  five-year  period

Properties  that is not a  Permitted  Lien.  The Liens  granted to Lender  under
Section 5 hereof are first priority Liens, subject only to Permitted Liens.

          7.1.8  Accounts.  Lender may rely, in  determining  which  Accounts of
Borrower are Eligible Accounts,  on all statements and  representations  made by
Borrower with respect to any Account or Accounts.  Unless otherwise indicated in
writing to Lender, with respect to each Account:

                   (i) It is genuine and in all respects what it purports to be,
and it is not evidenced by a judgment;

                   (ii)  It  arises  out of a  completed,  bona  fide  sale  and
delivery of goods or rendition of services by

Borrower in the ordinary course of its business and in accordance with the terms
and conditions of all purchase  orders,  contracts or other  documents  relating
thereto  and forming a part of the  contract  between  Borrower  and the Account
Debtor;

                   (iii) It is for a liquidated amount maturing as stated in the
duplicate  invoice covering such sale or rendition of services,  a copy of which
has been furnished or is available to Lender;

                   (iv) Such Account, and Lender's security interest therein, is
not subject to any offset, Lien, deduction,  defense,  dispute,  counterclaim or
any other adverse  condition,




                                       19
<PAGE>


except for disputes  resulting in returned goods where the amount in controversy
is deemed by Lender to be immaterial,  and each such Account is absolutely owing
to Borrower and is not contingent in any respect or for any reason;

deficiency  shall arise,  Borrower and each  Guarantor  shall remain jointly and

Property of a similar nature,  as it pertains to the Collateral,  in advertising
for sale and selling any Collateral and Borrower's rights under all licenses and
all franchise agreements shall inure to Lender's benefit.

schedule or in any Guaranty  Agreement given to Lender or contained in any other
agreement between Lender and Borrower,  heretofore,  concurrently,  or hereafter
entered  into,  shall  be  deemed   cumulative  to  and  not  in  derogation  or
substitution  of any of the  terms,  covenants,  conditions,  or  agreements  of
Borrower  herein  contained.  The  failure or delay of Lender to require  strict
performance  by Borrower of any  provision  of this  Agreement or to exercise or
enforce any rights,  Liens,  powers,  or remedies  hereunder or under any of the
aforesaid  agreements  or other  documents or security or  Collateral  shall not
operate as a waiver of such performance, Liens, rights, powers and remedies, but
all such  requirements,  Liens,  rights,  powers, and remedies shall continue in
full  force and  effect  until all Loans and all other  Obligations  owing or to
become owing from  Borrower to Lender shall have been fully  satisfied.  None of
the  undertakings,  agreements,  warranties,  covenants and  representations  of
Borrower  contained in this  Agreement or any of the other Loan Documents and no
Event of Default by Borrower  under this  Agreement or any other Loan  Documents

BUT  NOT  INCLUDING  ANY  LOSSES  CAUSED  BY THE  GROSS  NEGLIGENCE  OR  WILLFUL
MISCONDUCT OF ANY SUCH INDEMNIFIED  PERSON,  AND BORROWER SHALL REIMBURSE LENDER
AND EACH OTHER INDEMNIFIED PERSON FOR ANY EXPENSES (INCLUDING IN CONNECTION WITH
THE  INVESTIGATION  OF,  PREPARATION  FOR OR DEFENSE OF ANY ACTUAL OR THREATENED
CLAIM,  ACTION OR  PROCEEDING  ARISING  THEREFROM,  INCLUDING  ANY SUCH COSTS OF
RESPONDING TO DISCOVERY  REQUESTS OR SUBPOENAS,  REGARDLESS OF WHETHER LENDER OR
SUCH  OTHER  INDEMNIFIED  PERSON  IS A  PARTY  THERETO).  WITHOUT  LIMITING  THE
GENERALITY OF THE FOREGOING,  THIS INDEMNITY SHALL EXTEND TO ANY CLAIMS ASSERTED
AGAINST  LENDER  OR ANY  OTHER  INDEMNIFIED  PERSON  BY  ANY  PERSON  UNDER  ANY
ENVIRONMENTAL LAWS OR SIMILAR LAWS BY REASON OF BORROWER'S OR ANY OTHER PERSON'S

OR  HAZARDOUS  WASTE  MATERIALS OR OTHER TOXIC  SUBSTANCES.  BORROWER MAY SELECT
COUNSEL WITH RESPECT TO ANY LOSSES;  PROVIDED,  HOWEVER, EACH INDEMNIFIED PERSON
SHALL  HAVE  THE  RIGHT  TO  MONITOR  THE  PROGRESS  OF ANY  CLAIMS,  SUITS  AND
ADMINISTRATIVE  PROCEEDINGS  DEFENDED BY BORROWER HEREUNDER WITH COUNSEL OF SUCH
INDEMNIFIED  PERSON'S  CHOICE,  OR CONDUCT ITS DEFENSE  THROUGH  COUNSEL OF SUCH
INDEMNIFIED  PERSON'S  CHOICE,  IN THE EVENT  THAT (I) SUCH  INDEMNIFIED  PERSON
DETERMINES  IN GOOD FAITH THAT THE CONDUCT OF ITS  DEFENSE BY BORROWER  COULD BE
MATERIALLY  PREJUDICIAL  TO SUCH  INDEMNIFIED  PERSON'S  INTERESTS OR THAT OTHER
REASONABLE GROUNDS EXIST WHICH DEMONSTRATE A LACK OF EFFECTIVENESS OR HIGH LEVEL
OF  QUALITY  IN THE  CONDUCT  OF SUCH  DEFENSE  BY  BORROWER,  AND (II) PRIOR TO
RETAINING SUCH COUNSEL FOR SUCH PURPOSE,  SUCH INDEMNIFIED  PERSON SHALL CONSULT
WITH  BORROWER AND SHALL  ATTEMPT IN GOOD FAITH TO AGREE UPON COUNSEL TO CONDUCT
THE DEFENSE ON BEHALF OF BORROWER AND SUCH INDEMNIFIED  PERSON, AND IN EACH CASE
THE FEES AND DISBURSEMENTS OF SUCH COUNSEL SHALL BE PAID BY BORROWER;  PROVIDED,
HOWEVER,  THAT IF SUCH MUTUAL  AGREEMENT IS NOT REACHED WITHIN A REASONABLE TIME
ON SELECTING COUNSEL, THEN SUCH INDEMNIFIED PERSON MAY RETAIN ITS OWN COUNSEL AT
BORROWER'S  EXPENSE.  NOTWITHSTANDING  ANY CONTRARY PROVISION OF THIS AGREEMENT,
THE  OBLIGATION OF BORROWER UNDER THIS SECTION 11.2 SHALL SURVIVE THE PAYMENT IN
FULL OF THE OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

     11.3 Modification of Agreement; Sale of Interest. This Agreement may not be
modified,  altered or  amended,  except by an  agreement  in  writing  signed by
Borrower and Lender.  Borrower may not sell,  assign or transfer any interest in
this Agreement,  any of the other Loan Documents, or any of the Obligations,  or
any portion thereof,  including Borrower's rights, title,  interests,  remedies,
powers, and duties hereunder or thereunder. Borrower hereby consents to Lender's
participation,  sale, assignment,  transfer or other disposition, at any time or
times  hereafter,  of this Agreement and any of the other Loan Documents,  or of
any portion hereof or thereof,  including  Lender's  rights,  title,  interests,
remedies,  powers,  and  duties  hereunder  or  thereunder.  In the  event  of a
participation,  Lender will continue to administer this Agreement and any of the
other Loan Documents as the representative of such participants.  In the case of
an assignment,  the assignee shall have, to the extent of such  assignment,  the
same rights,  benefits and obligations as it would if it were "Lender" hereunder
and  Lender  shall  be  relieved  of all  obligations  hereunder  upon  any such
assignment.  Borrower  agrees  that it will use its best  efforts  to assist and
cooperate with Lender in any manner reasonably requested by Lender to effect the
sale of  participations  in or  assignments  of any of the Loan Documents or any
portion thereof or interest therein,  including  assisting in the preparation of
appropriate  disclosure  documents.  Borrower  further  agrees  that  Lender may
disclose  credit  information  regarding  Borrower and its  Subsidiaries  to any
potential Participant or assignee.

     11.4  Severability.  Wherever  possible,  each  provision of this Agreement
shall  be  interpreted  in  such  manner  as to be  effective  and  valid  under
Applicable Law, but if any


                                       25
<PAGE>

provision of this Agreement  shall be prohibited by or invalid under  Applicable
Law, such provision shall be ineffective  only to the extent of such prohibition
or  invalidity,  without  invalidating  the  remainder of such  provision or the
remaining provisions of this Agreement.

     11.5 Successors and Assigns.  This Agreement,  the Other Agreements and the
Security  Documents  shall be  binding  upon and  inure  to the  benefit  of the
successors  and assigns of Borrower  and Lender  permitted  under  Section  11.3
hereof.

     11.6  Cumulative  Effect;  Conflict of Terms.  The  provisions of the Other
Agreements  and the  Security  Documents  are hereby  made  cumulative  with the
provisions of this Agreement. Except as otherwise provided in Section 3.2 hereof
and except as otherwise  provided in any of the other Loan Documents by specific
reference  to the  applicable  provision  of this  Agreement,  if any  provision
contained in this Agreement is in direct  conflict with, or  inconsistent  with,
any provision in any of the other Loan  Documents,  the  provision  contained in
this Agreement shall govern and control.

     11.7  Execution  in  Counterparts.  This  Agreement  may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and  delivered  shall be deemed to be an original

same instrument.

warranties and agreements herein, the parties agree as follows:

                                    ARTICLE I

                                PURCHASE AND SALE

     1.1 Purchase and Sale of the Note and the Warrants. Subject to the terms of
this  Agreement,  Seller agrees to and does hereby  issue,  sell and deliver the
Note and the  Warrants to  Purchaser  at the Closing  (as defined  herein),  and
Purchaser  agree to and do hereby  purchase and accept the Note and the Warrants
from Seller.

     1.2  Consideration  for Purchase of the Note.  Subject to the terms of this
Agreement,  Purchaser hereby agrees to pay to Seller,  by check or wire transfer
to the  account  of Black  Warrior,  $2,000,000,  as the  consideration  for the
purchase of the Note (the "Note Consideration"),  in one or more advances, which
advances shall be made at Purchaser's  sole and absolute  discretion.  Purchaser
hereby  agrees  to  exercise  reasonable  good  faith  in  the  exercise  of its
discretion. Interest under the Note shall accrue on amounts actually advanced.

     1.3  Acknowledgment  of Prior  Advances.  Seller hereby  acknowledges  that
$500,000 of the total $2,000,000 Note  Consideration has, as of the date of this
Agreement, been advanced by Purchaser for Seller's account.

     1.4  Consideration  for Purchase of the  Warrants.  Subject to the terms of
this Agreement,  Purchaser  hereby agree to pay by check or wire transfer to the
account  of Black  Warrior  $0.03  per  share  subject  to the  Warrants  as the
consideration  for the purchase of each of the Warrants  issued and to be issued
hereunder (the "Warrant  Consideration";  the Note Consideration and the Warrant
Consideration are collectively referred to herein as the "Consideration").

     1.5 Origination  Fee. Seller agrees to pay Purchaser at Closing and at each
other time an advance of the Note Consideration is made, an origination fee (the
"Origination  Fee") equal to 2% of the entire amount of each such  advance,  for
the payment of the Note Consideration.

     1.6 Subordination. Purchaser agrees that the indebtedness hereunder and the
security granted therefor are subject to the Subordination  Agreement with Fleet
Capital   Corporation  (the  "Senior  Lender"),   pursuant  to  which  Purchaser
subordinates its security  interests and rights to the security interests of the
Senior Lender,  except for  Purchasers's  security  interest in certain offshore
skids owned by the Seller.

     1.7  Future  Financings.  If  Seller,  at any  time so long as the  Note is
outstanding,  intends  to  issue or sell  any  shares  of  capital  stock,  debt
securities or securities  convertible into,  exchangeable for or exercisable for
shares of capital stock or debt  securities (a  "Financing"),  Seller shall give
Purchaser  written  notice (the "Offer") of its intent to engage in a Financing,
specifying its basic terms and conditions.  If Purchaser gives notice to Seller,
specifying  Purchaser's  basic  terms and  conditions,  of its intent to provide
Financing on a basis  materially  similar to the proposal set forth in the Offer
within five (5) business days after receipt of the Offer (a "Financing Notice"),
then Seller shall be obligated to consummate  the Financing  only with Purchaser
and Purchaser  shall be obligated to provide the financing at the time committed
by the third party whose  commitment  gave rise to the Offer.  If Purchaser does
not within five (5)  business  days after  receipt of the Offer give to Seller a
Financing  Notice,  Purchaser  shall be deemed 


                                       2
<PAGE>


to have waived their rights to provide the  Financing  under this  Section,  and
Seller may  thereafter  obtain such  Financing  from a third party or parties if
such third party  Financing is on the same basic terms and  conditions  as those
set forth in the Offer.  Any proposed  Financing on terms  materially  different
from those basic terms and  conditions  in the Offer deemed  waived by Purchaser
shall require a new Offer and  compliance by Seller with the  provisions of this
Section.  Notwithstanding the foregoing,  Seller shall not be required to comply
with this Section in connection  with: (i) the issuance and sale of Common Stock
or  convertible  securities in connection  with any employee  stock option plan,
arrangement  or  agreement  now or  hereafter  in effect;  (ii) the  issuance of
capital  stock of Seller upon  exercise of the Warrants or  otherwise  issued to
Purchaser or their assigns; (iii) the issuance of capital stock upon exercise of
any stock  purchase  warrant or option  (other than the  options  referred to in
clause (i) above) or other convertible  security  outstanding on the date hereof
or hereafter issued; (iv) a public offering of securities;  or (v) any loan from
a regular commercial lending source.

     1.8 Future  Advances.  The  exercise of  Purchaser's  discretion  in making
advances  after the date hereof is  conditioned  upon the  delivery by Seller to
Purchaser of the following:

         (a) a written request for such advance at the address for the Purchaser
     in Section 5.2 hereof,  setting  forth (i) the amount  requested,  (ii) the
     account to which such  advance is to be funded,  and (iii) the proposed use
     of such advance, which shall be in accordance with Section 2.19 herein;

         (b) a certificate  of an officer of Seller  certifying  that, as of the
     date of the  advance,  no Event of Default  hereunder  has  occurred,  that
     Seller  is in  compliance  with all  covenants  herein  and that all of the
     representations  and warranties set forth herein are true and correct as of
     such date;

         (c) such security documents  respecting the assets of the Seller or its
     Active Subsidiary as may be reasonably requested by Purchaser;

         (d) such other  documents,  certificates,  agreements or instruments as
     may be reasonably  requested by Purchaser in connection  with any or all of
     the foregoing; and

         (e) payment by Seller of any and all expenses or other  amounts due and
     owing to Purchaser; and

         (f)  Warrants to  purchase a number of shares of Common  Stock equal to

                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF SELLER

     Seller  represents  and  warrants to Purchaser  that each of the  following
statements (i) are true and correct on the date hereof and (ii) will be true and
correct  in all  material  respects  on  the  date  each  advance  of  the  Note
Consideration is made:

     2.1 Organization, Standing and Qualification. Each of Black Warrior and the
Active Subsidiary is a corporation duly organized,  validly existing and in good
standing under the laws of the state 



                                       3
<PAGE>

of its incorporation and has all requisite corporate power and authority to own,
lease and operate its properties and to carry on its business as it is now being
conducted.  Each of Black  Warrior and the Active  Subsidiary  is  licensed  and
qualified to do business as a foreign  corporation in each jurisdiction in which
the  character  of  its  properties,  owned  or  leased,  or the  nature  of its
activities makes such qualification or license necessary.

     2.2 Authority; No Defaults. Each of Black Warrior and the Active Subsidiary
has all requisite  corporate  power and authority to enter into the  Transaction
Documents and to consummate the transactions contemplated thereby. The execution
and  delivery  of  the  Transaction   Documents  and  the  consummation  of  the
transactions  contemplated  thereby have been duly  authorized  by all necessary
corporate  action on the part of Seller.  The  Transaction  Documents  have been
executed and delivered by Seller and constitute the valid and binding obligation
of Seller,  enforceable in accordance  with their terms,  subject to bankruptcy,
insolvency,  moratorium  and other  similar  laws  affecting  creditors'  rights
generally  and  general   principles  of  equity  (regardless  of  whether  such
enforceability is considered in a proceeding in equity or at law). The execution
and delivery of the  Transaction  Documents do not, and the  consummation of the
transactions  contemplated  hereby and thereby will not, conflict with or result
in a breach of or the  acceleration  of any  obligation  under,  or constitute a
default or event of default  (or event  which,  with  notice or lapse of time or
both,  would  constitute a default or event of default) under,  any provision of
any charter,  bylaw,  indenture,  mortgage,  lien, lease,  agreement,  contract,
instrument, order, judgment, decree, ordinance or regulation, or any restriction
to which any  property  of Seller is  subject or by which  Seller is bound,  the
effect of which would be materially  adverse to Seller.  Seller is not, nor does
Seller have knowledge that it is alleged to be, in material violation or default
of any  applicable  law,  statute,  order,  rule or  regulation  promulgated  or
judgment  entered by any court,  administrative  agency or  commission  or other
governmental  agency or  instrumentality,  domestic or foreign (a  "Governmental
Entity"),  relating to or affecting the  operation,  conduct or ownership of the
property or business of Seller.

     2.3 Approvals.  There is no legal  impediment to the execution and delivery
of  the  Transaction   Documents  by  Seller  or  to  the  consummation  of  the
transactions  contemplated  thereby,  and no filing  or  registration  with,  or
authorization,  consent or approval of, a Governmental  Entity,  shareholders or
any  other  third  party is  necessary  for the  consummation  by  Seller of the
transactions contemplated thereby.

     2.4 Charter and Bylaws. Seller has furnished to Purchaser true and complete
copies of its charter and bylaws,  each as amended to date and as  presently  in
effect.

     2.5 SEC Documents.


         (a)  Seller  has made all  filings  with the  Securities  and  Exchange
     Commission  ("SEC") that it has been required to make under the  Securities
     Act of 1933, as amended (the "Securities Act"), and the Securities Exchange
     Act of 1934,  as amended  (the  "Exchange  Act") since  December  31, 1994.
     Seller has  provided to  Purchaser  true,  complete  and correct  copies of
     Seller's  annual report on Form 10-K  ("Seller's Form 10-K") for the fiscal
     year  ended  December  31,  1997,  together  with all  amendments  thereto,
     Seller's  quarterly report on Form 10-Q for the fiscal quarters ended March
     31, 1998 and June 30, 1998, together with all amendments  thereto,  and any
     and all  filings  with  the SEC made by  Seller  (including  all  requested
     exhibits  to such  filings)  since  the  filing of said Form 10-K (all such
     documents that have been filed with the SEC, as amended, are referred to as
     the "Seller SEC Documents").  As of their  respective  dates, and except as
     amended,  Seller SEC Documents  complied in all material  respects with the
     requirements of the Securities Act or the Exchange Act, as the case may be,
     and none of Seller  SEC  Documents  contained  any  untrue


                                       4
<PAGE>

     statement of a material  fact or omitted to state a material  fact required
     to be stated therein or necessary to make the statements  therein, in light
     of the circumstances under which they were made, not misleading.

         (b) The  financial  statements  of Seller  included  in the  Seller SEC
     Documents  comply  as to  form in all  material  respects  with  applicable
     accounting requirements and with the published rules and regulations of the
     SEC with respect  thereto,  have been prepared in accordance with generally
     accepted  accounting  principles  ("GAAP")  applied on a  consistent  basis
     during  the  periods  involved  (except  as may be  indicated  in the notes
     thereto or, in the case of the unaudited  statements,  as permitted by Form
     10-Q) and fairly present (subject, in the case of the unaudited statements,
     to normal recurring audit adjustments) the consolidated  financial position
     of Seller as of the  dates  thereof  and the  consolidated  results  of its
     operations and cash flows for the periods then ended.  Since June 30, 1998,
     (i) there  have been no  material  adverse  changes in  Seller's  business,
     operations or financial  condition and (ii) Seller's  operations  have been
     conducted in the ordinary course of business except as disclosed in writing
     to Purchaser.

     2.6 Litigation. Except as set forth on Schedule 2.6, as of the date of this
Agreement,  there is no suit, action, proceeding or investigation pending or, to
the best knowledge of Seller,  threatened  against or affecting  Seller,  nor is
there any  outstanding  judgment,  order,  writ,  injunction  or decree  against
Seller, which judgment would have a material adverse effect on Seller. Seller is
not subject to any court order, writ, injunction,  decree,  settlement agreement
or  judgment  that  contains  or  orders  any  on-going   obligations,   whether
prohibitory  or  mandatory  in nature,  the  performance  of which  would have a
material adverse effect on Seller.

     2.7  Capitalization.  Black  Warrior has  authorized  capital  stock of (a)
____________  shares of Common Stock of which, as of the date hereof,  there are
____________  shares  issued  and  outstanding,  and  (b)  _________  shares  of
preferred stock of which, as of the date hereof,  there are no shares issued and
outstanding.  All of the issued and outstanding shares of Common Stock were duly
and  validly  issued  and  are  fully  paid  and  non-assessable.  None  of  the
outstanding  shares  of  Common  Stock  has  been  issued  in  violation  of any
preemptive  rights of the current or past stockholders of Seller. As of the date
hereof,  Black  Warrior has reserved for issuance (i) an aggregate of __________
shares of Common  Stock  issuable  on issuance  of stock  options to  employees,
officers,  directors  and other  persons,  and the Board of  Directors  of Black
Warrior  has  approved  amendments  to the plans in respect  of such  options to
increase the shares available thereunder to an aggregate of __________ shares of
Common Stock,  subject to the approval of the shareholders of Black Warrior, and
(ii) an aggregate of __________  shares of Common Stock issuable on the exercise
of outstanding warrants,  options, or of convertible securities other than those

(i) and (ii), there are no outstanding options,  warrants or rights to subscribe
for, or  commitments of any character  whatsoever  relating to, or securities or
rights  convertible  into or  exchangeable  for,  shares of the capital stock of
Black Warrior or contracts, commitments, understandings or arrangements by which
Black Warrior is or may be obligated to issue  additional  shares of its capital
stock or options,  warrants,  or rights to  purchase  or acquire any  additional
shares of its capital  stock.  All of the Common Stock issued on the exercise of
the  Warrants  will be fully  paid,  non-assessable  and  free and  clear of any
Encumbrances.  As used in this  Agreement,  the  term  "Encumbrance"  means  and
includes (i) any  security  interest,  mortgage,  deed of trust,  lien,  charge,
pledge,  proxy, adverse claim, equity, power of attorney,  or restriction of any
kind,  including  but not limited to, any  restriction  or servitude on the use,
transfer,  receipt of income,  or other exercise of any attributes of ownership,
and (ii) any Uniform Commercial Code financing statement or other public filing,
notice or 


                                       5

     2.8  Subsidiaries.  Schedule 2.8 sets forth the only active  subsidiary  of
Seller,  including state or country of organization and address of its principal
executive offices ("Active Subsidiary").  For purposes of this Agreement and the
other  agreements  contemplated  hereby,  the  Active  Subsidiary  is  the  only
"subsidiary" of Seller.  Schedule 2.8 also discloses four inactive  corporations
and/or limited partnerships owned by Seller (the "Inactive Organizations"),  all
four of  which  are at this  time  inactive,  defunct,  and  have no  value.  No
representation,   warranty,  financial  standard  or  other  provision  of  this
Agreement,  or any agreement  contemplated  hereby,  shall be deemed violated by
virtue  of the fact  that any of the  Inactive  Organizations  do not meet  said
representation, warranty, financial standard or other provision. However, if any
Inactive  Organization  begins to conduct any business (other than activities to
"wind down" such organization) such Inactive Organization shall be considered an
Active  Subsidiary  (and cease to be an Inactive  Organization)  from that point
forward. The Active Subsidiary is a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its organization, has
all requisite  corporate  power and authority to own, to lease or to operate its
properties and to carry on its business as it is now being conducted and is duly
qualified or licensed to do business in each jurisdiction in which the character
of its properties,  owned or leased,  or the nature of its activities makes such
qualification  or license  necessary,  unless the  failure to be so  licensed or
qualified  would not have a material,  adverse  effect on Seller.  Except as set
forth in Schedule  2.8, all  outstanding  shares of capital  stock of the Active
Subsidiary  were duly and validly issued and are fully paid,  nonassessable  and
owned by Seller or a subsidiary of Seller,  free and clear of all  Encumbrances.
There are no  options,  warrants  or other  rights,  agreements  or  commitments
(including  preemptive  rights)  obligating  Seller or the Active  Subsidiary to
issue, to sell or to transfer any shares of capital stock or other securities of
the  Active  Subsidiary.  There are  _____  shares  of  capital  stock of Active
Subsidiary issued and outstanding, all of which has been pledged to Purchaser.

     2.9  Liabilities.  Except  as set  forth in  Schedule  2.9,  Seller  has no
liabilities or obligations,  either accrued, absolute,  contingent, or otherwise
that have a material  adverse  effect on the value or  business  of Seller,  and
Seller has no knowledge of any potential  liability that it reasonably  believes
would  likely  result in a material  adverse  effect on the value or business of
Seller, other than those (a) reflected or reserved against in the balance sheets
reported on Seller's  Form 10-Q for the fiscal  quarter  ended June 30, 1998, or
(b) incurred in the ordinary course of business since June 30, 1998.

     2.10 Licenses,  Permits,  Authorizations,  Etc. Seller holds all approvals,
authorizations,  consents,  licenses, orders, franchises,  rights, registrations
and permits of any type required to operate its business as presently conducted.
The  execution  and  delivery  of this  Agreement  and the  consummation  of the
transactions   contemplated   hereby   will  not   result  in  any   revocation,
cancellation,  suspension or modification  of any such approval,  authorization,
consent license, order, franchise, right, registration or permit.

     2.11 Title to Assets; Encumbrances. Except as set forth in Schedule 2.11:

         (a) Seller has good and indefeasible title to its assets, whether real,
     personal or intangible, free and clear of all Encumbrances except (i) liens
     for current taxes and  assessments  not yet due or being  contested in good
     faith by appropriate  proceedings,  (ii) mechanic's liens arising under the
     operation of law for actions  contested in good faith or for which  payment
     arrangements  have been made,  (iii) liens granted or incurred by Seller in
     the  ordinary  course of its business or  financing  of  equipment,  office
     space,  furniture and computers in the ordinary course 

                                       6
<PAGE>


     of its business, and (iv) easements,  rights of way, encroachments or other
     restrictions  or matters  affecting  title  which do not prevent the assets
     from being used for the purpose for which they are currently being used;

         (b) There are no parties in  possession  of any of the assets of Seller
     other than personal  property held by third parties in the  reasonable  and
     ordinary course of business. Seller enjoys full, free and exclusive use and
     quiet  enjoyment of its assets and its rights  pertaining  thereto.  Seller
     enjoys peaceful and undisturbed  possession under all leases under which it
     is a lessee, and all such leases are legal,  valid and binding  obligations
     of Seller, enforceable against Seller in accordance with their terms.

     2.12 Taxes and  Returns.  Seller has filed all  required  tax  returns  and
reports.  Seller has paid all taxes,  assessments and  governmental  charges and
penalties which it has incurred, except such as are being or may be contested in
good faith by appropriate  proceedings.  Seller is not delinquent in the payment
of any tax,  assessment or governmental  charge.  No deficiencies  for any taxes
have been proposed,  asserted,  or assessed against Seller,  and no requests for
waivers of the time to assess any such tax are pending. For the purposes of this
Agreement,  the term  "tax"  (including,  with  correlative  meaning,  the terms
"taxes" and  "taxable")  shall  include all  federal,  state,  local and foreign
income, profits,  franchise,  gross receipts,  payroll, sales, employment,  use,
property,  withholding,  excise and other taxes,  duties or  assessments  of any
nature whatsoever,  together with all interest,  penalties and additions imposed
with respect to such amounts.

     2.13  Insurance.  Each  policy  of  property,  fire and  casualty,  product
liability, worker's compensation, professional liability and title insurance and
other forms of insurance (except group,  health and life policies) and each bond
issued  or  posted  by any  person  with  respect  to any  operations  or  other
activities  of Seller  is, to the  knowledge  of Seller,  the  legal,  valid and
binding obligation of the insurer or bond issuer, enforceable in accordance with
its terms,  and is in an amount and provides for coverage as is customary in the
ordinary business practices of Seller's industry.

     2.14 Patents, Trademarks, Etc. Seller has no patents,  trademarks,  service
marks, works of authorship,  tradenames, brandnames or copyrights. Seller is not
using,  and does not have any plan to  manufacture,  use or sell anything  which
would violate or infringe on any patent or proprietary right (of which Seller is
aware) of any other person, firm or corporation or which would require a license
under  any such  patent  or  proprietary  right.  Seller  has not  received  any
communications  alleging that Seller has violated or, by conducting its business
as  proposed,  would  violate any of the  patents,  trademarks,  service  marks,
tradenames,   copyrights,   works  of  authorship  or  trade  secrets  or  other
proprietary rights in processes of any other person or entity.

     2.16 Compliance.  Except as set forth on Schedule 2.16, Seller has complied
in all material  respects with all laws,  and is not in violation of any charter
or other corporate restrictions or any law, ordinance, requirement,  regulation,
judgment,  injunction, award, decree, or other order applicable to its business.
There is no term or provision of any mortgage, indenture, contract, agreement or
instrument to which Seller is a party or by which it is bound,  any provision of
any state or federal judgment, decree, order, injunction, writ, statute, rule or
regulation  applicable  to or binding upon Seller,  which  materially  adversely
affects  or,  in the  future is  reasonably  likely  to  affect  materially  and
adversely the business, prospects, condition, affairs or operations of Seller or

statute,  ordinance,  rule,  regulation,  memorandum of understanding,  order or
notice  requirement  pertaining  to  the  collection,  transportation,  storage,
treatment, discharge, release or disposal of hazardous or non-hazardous waste or

operations  of Seller has ever been  conducted  nor have any of its assets  been

or inquiry  related to violations  under any  Applicable  Environmental  Law, or

responsible party for any facility under the Applicable  Environmental Laws, nor
does any fact or  circumstance  exist  which,  if disclosed  publicly,  would be
reasonably  likely to result in the service on Seller of any such notice.  There
has been no action taken, or omitted to be taken by Seller which has caused,  or
would be reasonably likely to cause, a "release" of any "hazardous substance" at
any "facility," without limitation,  within the meaning of such terms as defined
in the Applicable Environmental Laws.

Purchaser  or  its  counsel  by  Seller  in  connection  with  the  transactions

of the Person;  and (d) for all deferrals,  renewals,  extensions and refundings
of, and amendments,  modifications  and supplements to, any of the  indebtedness

     "Maturity Date",  when used with respect to this Note, means March 16, 2001
(or such earlier date upon which this Note becomes due and payable under Section
3.2).

     "Note" means this $2,000,000 10% Convertible  Promissory Note, as hereafter
amended, modified, substituted or replaced.

     "Person" means any  individual,  corporation,  limited  liability  company,

other  entity,  unincorporated  organization  or  government  or any  agency  or

                                   ARTICLE II

                             COMMITMENT AND ADVANCES

     2.1  Advances.  Subject  to the terms and  conditions  and  relying  on the
representations  and  warranties  set forth herein and in the other  Transaction
Documents,  Holder  agrees to advance to the Company a sum  equaling a principal
amount not to exceed $2,000,000 in one or more advances, which advances shall be
made at Holder's sole and absolute discretion.  Holder shall exercise reasonable
good  faith in the  exercise  of its  discretion,  and  shall  not  unreasonably
withhold  additional  advances.  All such  advances  shall mature and be due and
payable in full on the Maturity  Date (or such earlier date upon which this Note
becomes  due and payable  under  Section  3.2).  Each  advance  shall be made in
accordance  with the  procedures  set forth in Article  II,  Section  2.2 and as
provided in Article I, Section 1.8 of the Agreement.

     2.2 Borrowing  Procedures of Advances.  In order to effect an advance,  the
Company  shall  submit a Request  for  Advance  in writing  or by  telecopy  (or
telephone  notice  promptly  confirmed  in writing or by telecopy) to Holder not
later than 10:00 a.m., Houston, Texas time, on such dates as Company determines.
The  Requests for  Advances  shall refer to this Note and specify in  sufficient
detail the  corporate  use of the proceeds of such  Advance,  and the  principal
amount  of such  Advance.  The  obligation  of the  Holder  to make any  advance
pursuant  to such a Request for  Advance is subject to the  satisfaction  of the
Holder that (i) the proceeds  will be used for a proper  purpose and (ii) on the
date of such advance, no Default or Event of Default, as those terms are defined
herein, then exists or will exist after such advance is made.

     2.3  Interest.  From the  date of this  Note  through  the  Maturity  Date,
interest shall accrue hereunder on the unpaid outstanding  principal sum of this
Note at a rate equal to ten percent (10%) per annum calculated on the basis of a
360-day year. All past due amounts of principal and interest shall bear interest
at fifteen  percent  (15%) per annum  calculated  on the basis of a 360-day year
until paid.  The Company  acknowledges  that interest at the rate of ten percent
(10%) per annum on the  principal  amount of $500,000 has accrued since July 27,
1998 and is payable under this Note.

     2.4 Payment of Principal  and  Interest.  The principal and all accrued and
unpaid interest under this Note shall be due and payable in full on the Maturity
Date. At any time,  the Holder may, at its option and in lieu of cash,  elect to
be paid all  accrued  and unpaid  interest  owed to Holder by 
<PAGE>

the Company in the form of Common Stock, based on a price per share equal to the
Conversion  Price (the "Price Per Share").  The amount of all accrued and unpaid
interest  on the  Maturity  Date  shall be divided by the Price Per Share into a
whole number of shares of Common Stock,  with the remainder,  if any, being paid
in cash.

     2.5 Prepayments.  Subject to Holder's right to convert,  at any time before
the  Maturity  Date,  the  Company  may prepay  this Note,  in whole or in part,
without  penalty or  discount,  upon five days' prior  written  notice  given to
Holder  pursuant  to Section  7.5.  All  payments  made under this Note shall be
applied  first to accrued  interest,  and the  balance,  if any,  to  principal;
provided, however, that interest shall accrue on any remaining principal balance
and shall be payable at the rate provided above.

     2.6 Manner of Payment. Cash payments of principal and interest on this Note
will be made by  delivery  of a check to Holder at its  address  as set forth in
this Note or a wire transfer pursuant to instructions from Holder.

     2.7 Use of Proceeds.  The proceeds of all advances shall be used to provide
working  capital  required  by the  Company and to provide  funds  necessary  to
complete various capital projects, namely the construction and completion of two
offshore  "skids".  No portion of the  proceeds of any  Advance  under this Note
shall be used by the Company in any manner that might cause the borrowing or the
application  of  such  proceeds  to  violate  Regulation  U,  Regulation  T,  or
Regulation X or any other  regulation of the Federal Reserve Board or to violate
the  Securities  Exchange Act of 1934, as amended,  in each case as in effect on
the date of such borrowing and such use of proceeds.

                                   ARTICLE IV

                               CONVERSION OF NOTE

     Subject to and upon compliance with the provisions of this Article,  at the
option of Holder,  all or any part of this Note may be converted at any time, at
the principal  amount hereof together with accrued and unpaid interest  thereon,
into fully paid and  nonassessable  shares  (calculated as to each conversion to
the  nearest  1/100 of a share) of Common  Stock.  The  Conversion  Price  shall
initially be $2.25 per share.  Notwithstanding anything else to the contrary set
forth  herein,  the Holder shall have the right to convert this Note pursuant to
the terms set forth herein at any time, including the 30 Business Days following

Holder as to which Holder has elected to convert.


                                    ARTICLE V

                         ADJUSTMENT OF CONVERSION PRICE
<PAGE>

     5.1  Anti-Dilution  Provisions.  The  Conversion  Price shall be subject to
adjustment  from time to time as hereinafter  provided.  Upon each adjustment of
the Conversion  Price,  the holder of this Note shall  thereafter be entitled to
purchase, at the Conversion Price resulting from such adjustment,  the number of
shares of Common Stock  obtained by multiplying  the Conversion  Price in effect
immediately  prior  to such  adjustment  by the  number  of  shares  purchasable
pursuant  hereto  immediately  prior to such adjustment and dividing the product
thereof by the Conversion Price resulting from such adjustment.

     5.2 Adjustment of Conversion Price Upon Issuance of Common Stock.

         5.2.1 (A) If and whenever after the date hereof the Company shall issue
     or sell any Common Stock for no  consideration  or for a consideration  per
     share less than the Conversion Price,  issue  convertible  securities other
     than this Note,  issue  warrants  other than the Warrants  issued as of the
     date  hereof,  grant  stock  options,  or  issue  any  other  common  stock
     equivalent (other than shares reserved for issuance to officers, employees,
     directors,  consultants  or advisors  of the  Company  pursuant to existing
     stock option or restricted stock purchase plans) then, forthwith, upon such
     issue or sale,  the  Conversion  Price shall be reduced (but not increased,
     except as otherwise  specifically  provided in Section 5.2.2), to the lower
     price per share  (calculated to the nearest  one-ten  thousandth of a cent,
     but in any event not less than $0.001 per share).

               (B)  Notwithstanding  the  provisions  of this  Section  5.2,  no
     adjustment  shall be made in the  Conversion  Price in the  event  that the
     Company issues, in one or more transactions, (i) Common Stock upon exercise
     of any options  issued to  officers,  directors or employees of the Company
     pursuant to a stock option plan or an  employment,  severance or consulting
     agreement as now or hereafter in effect, in each case approved by the Board
     of Directors  (provided that the aggregate number of shares of Common Stock
     which may be issuable,  including  options issued prior to the date hereof,
     under all such employee  plans and  agreements  shall at no time exceed the
     number of such shares of Common Stock  outstanding  on the date hereof on a
     fully diluted basis that are issuable under  currently  effective  employee
     plans and  agreements);  (ii) Common Stock upon  conversion of this Note or
     any other warrant issued  pursuant to the terms of the Purchase  Agreement;
     (iii) Common Stock upon  exercise of any stock  purchase  warrant or option
     (other  than  the  options  referred  to in  clause  (i)  above)  or  other
     convertible  security  outstanding on the date hereof; or (iv) Common Stock
     issued as consideration in acquisitions.


<PAGE>


         5.2.2  For  purposes  of this  Section  5.2,  the  following  shall  be
     applicable:

         (A)  Issuance of Rights or Options.  In case at any time after the date
     hereof  the  Company  shall in any manner  grant  (whether  directly  or by
     assumption  in a merger or  otherwise)  any rights to  subscribe  for or to
     purchase,  or any options for the purchase of, Common Stock or any stock or
     securities   convertible  into  or  exchangeable  for  Common  Stock  (such
     convertible  or  exchangeable  stock  or  securities  being  herein  called
     "Convertible  Securities")  (other than  warrants,  options or  convertible
     securities  issued as  consideration  for or assumed in conjunction with an
     acquisition or to officers,  directors, or employees of the acquired entity
     in  conjunction  therewith),  whether or not such  rights or options or the
     right  to  convert  or  exchange  any  such   Convertible   Securities  are
     immediately exercisable, and the price per share for which shares of Common
     Stock are  issuable  upon the  exercise  of such  rights or options or upon
     conversion  or  exchange  of such  Convertible  Securities  (determined  by
     dividing  (i) the total  amount,  if any,  received  or  receivable  by the
     Company as consideration  for the granting of such rights or options,  plus
     the minimum aggregate amount of additional  consideration,  if any, payable
     to the Company upon the exercise of such rights or options, or plus, in the
     case of such rights or options that relate to Convertible  Securities,  the
     minimum aggregate amount of additional consideration,  if any, payable upon
     the issue or sale of such Convertible Securities and upon the conversion or
     exchange  thereof,  by (ii) the  total  maximum  number of shares of Common
     Stock  issuable  upon the  exercise  of such  rights or options or upon the
     conversion or exchange of all such Convertible Securities issuable upon the
     exercise of such rights or options) shall be less than the Conversion Price
     in effect as of the date of granting such rights or options, then the total
     maximum number of shares of Common Stock issuable upon the exercise of such
     rights or options or upon  conversion  or exchange of all such  Convertible
     Securities  issuable  upon the exercise of such rights or options  shall be
     deemed to be  outstanding  as of the date of the granting of such rights or
     options and to have been  issued for such price per share,  with the effect
     on the  Conversion  Price  specified  in Section  5.2.1  hereof.  Except as
     provided in Section 5.2.2 hereof,  no further  adjustment of the Conversion
     Price shall be made upon the actual  issuance  of such  Common  Stock or of
     such Convertible Securities upon exercise of such rights or options or upon
     the actual  issuance of such Common  Stock upon  conversion  or exchange of
     such Convertible Securities.

         (B) Change in Option Price or  Conversion  Rate.  Upon the happening of
     any of the following events,  namely, if the purchase price provided for in
     any right or option  referred to in Section  5.2.2  above,  the  additional
     consideration,  if any,  payable  upon the  conversion  or  exchange of any
     Convertible  Securities referred to in Section 5.2.2(A) hereof, or the rate
     at which any Convertible Securities referred to in Section 5.2.2(A) hereof,
     are convertible  into or exchangeable  for Common Stock shall change (other
     than  under  or  by  reason  of  provisions  designed  to  protect  against
     dilution), the Conversion Price then in effect hereunder shall forthwith be
     readjusted  (increased or decreased,  as the case may be) to the Conversion
     Price that would have been in effect at such time had such rights,  options
     or  Convertible  Securities  still  outstanding  provided  for such changed
     purchase price,  additional  

<PAGE>

     consideration or conversion rate, as the case may be, at the time initially
     granted,  issued or sold.  On the  expiration  of any such  option or right
     referred to in Section 5.2.2(A)  hereof,  or on the termination of any such
     right to convert or exchange any such Convertible Securities referred to in
     Section  5.2.2(A)  hereof,  the Conversion  Price then in effect  hereunder
     shall forthwith be readjusted (increased or decreased,  as the case may be)
     to the Conversion  Price that would have been in effect at the time of such
     expiration or termination had such right, option or Convertible Securities,
     to  the  extent  outstanding   immediately  prior  to  such  expiration  or
     termination,  never been  granted,  issued or sold,  and the  Common  Stock
     issuable  thereunder  shall no longer be deemed to be  outstanding.  If the
     purchase price provided for in Section 5.2.2(A) hereof or the rate at which
     any  Convertible  Securities  referred  to in Section  5.2.2(A)  hereof are
     convertible  into or exchangeable  for Common Stock shall be reduced at any
     time under or by reason of  provisions  with  respect  thereto  designed to
     protect against dilution, then in case of the delivery of Common Stock upon
     the exercise of any such right or option or upon  conversion or exchange of
     any such  Convertible  Securities,  the  Conversion  Price  then in  effect
     hereunder  shall,  if not already  adjusted,  forthwith be adjusted to such
     amount  as would  have  obtained  had such  right,  option  or  Convertible
     Securities  never been issued as to such Common  Stock and had  adjustments
     been made upon the issuance of the Common Stock delivered as aforesaid, but
     only if as a result of such adjustment the Conversion  Price then in effect
     hereunder is thereby reduced.

         (C)  Consideration  for  Stock.  In case at any  time  Common  Stock or
     Convertible Securities or any rights or options to purchase any such Common
     Stock or  Convertible  Securities  shall be issued  or sold for  cash,  the
     consideration  therefor  shall be deemed to be the amount  received  by the
     Company  therefor.  In case  at any  time  any  Common  Stock,  Convertible
     Securities  or any rights or options to purchase  any such Common  Stock or
     Convertible Securities shall be issued or sold for consideration other than
     cash,  the  amount of the  consideration  other than cash  received  by the
     Company  shall be deemed  to be the fair  value of such  consideration,  as
     determined  reasonably  and in good faith by the Board of  Directors of the
     Company.  In case at any time any Common Stock,  Convertible  Securities or
     any  rights  or  options  to  purchase  any  Common  Stock  or  Convertible
     Securities  shall be issued in connection with any merger or  consolidation
     in  which  the  Company  is  the  surviving  corporation,   the  amount  of
     consideration  received  therefor shall be deemed to be the fair value,  as
     determined  reasonably  and in good faith by the Board of  Directors of the
     Company,  of such  portion of the assets and  business of the  nonsurviving
     corporation as such Board of Directors may determine to be  attributable to
     such Common Stock,  Convertible  Securities,  rights or options as the case
     may be. In case at any time any rights or options to purchase any shares of
     Common Stock or Convertible  Securities  shall be issued in connection with
     the  issuance  and  sale  of  other  securities  of the  Company,  together
     consisting  of one  integral  transaction  in  which  no  consideration  is
     allocated to such rights or options by the parties,  such rights or options
     shall be deemed to have been issued without consideration.

         (D) Record  Date.  In the case the  Company  shall take a record of the
     holders  of its  Common  Stock for the  purpose  of  entitling  them (i) to
     receive  a  dividend  or other  distribution  payable  in  Common  Stock or
     Convertible Securities, or (ii) to subscribe for or

<PAGE>

     purchase  Common  Stock or  Convertible  Securities,  then such record date
     shall be deemed to be the date of the  issuance or sale of the Common Stock
     or Convertible Securities deemed to have been issued or sold as a result of
     the  declaration of such dividend or the making of such other  distribution
     or the date of the granting of such right of subscription  or purchase,  as
     the case may be.

         (E) Treasury Shares.  The number of shares of Common Stock  outstanding
     at any given time shall not include shares owned directly by the Company in
     treasury,  and the  disposition  of any such shares shall be  considered an
     issuance or sale of Common Stock for the purpose of this Section 5.2.

     5.3 Stock  Dividends.  In case the Company shall declare a dividend or make
any other  distribution upon any shares of the Company,  payable in Common Stock
or Convertible Securities,  any Common Stock or Convertible  Securities,  as the
case may be,  issuable  in payment of such  dividend  or  distribution  shall be
deemed to have been issued or sold without consideration.

     5.4 Stock Splits and Reverse Splits. In the event that the Company shall at
any time subdivide its outstanding  shares of Common Stock into a greater number
of shares,  the Conversion Price in effect immediately prior to such subdivision
shall be  proportionately  reduced and the number of Shares into which this Note
may be converted  immediately prior to such subdivision shall be proportionately
increased,  and conversely,  in the event that the outstanding  shares of Common
Stock  shall at any time be  combined  into a  smaller  number  of  shares,  the
Conversion  Price  in  effect  immediately  prior to such  combination  shall be
proportionately  increased  and the number of Shares into which this Note may be
converted  immediately  prior  to  such  combination  shall  be  proportionately
reduced.  Except as provided in this Section 5.4 no adjustment in the Conversion
Price and no change in the number of Shares  shall be made under this  Article V
as a result of or by reason of any such subdivision or combination.

     5.5  Reorganizations  and Asset  Sales.  If any capital  reorganization  or
reclassification  of the capital  stock of the  Company,  or any  consolidation,
merger or share  exchange  of the  Company  with  another  Person,  or the sale,
transfer  or other  disposition  of all or  substantially  all of its  assets to
another  Person  shall be  effected in such a way that  holders of Common  Stock
shall be entitled to receive capital stock, securities or assets with respect to
or in exchange for their shares, then the following provisions shall apply:

         5.5.1  As  a  condition  of  such   reorganization,   reclassification,
     consolidation,  merger, share exchange, sale, transfer or other disposition
     (except as otherwise provided below in Section 5.5.3),  lawful and adequate
     provisions  shall be made whereby the holder of this Note shall  thereafter
     have the right to  purchase  and  receive  upon the  terms  and  conditions
     specified  in this Note and in lieu of the shares  immediately  theretofore
     receivable upon the exercise of the rights represented  hereby, such shares
     of capital  stock,  securities  or assets as may be issued or payable  with
     respect to or in exchange for a number of outstanding shares of such Common
     Stock equal to the number of shares  immediately  theretofore so receivable

<PAGE>

     had such  reorganization,  reclassification,  consolidation,  merger, share
     exchange  or  sale  not  taken  place,  and in any  such  case  appropriate
     provision reasonably satisfactory to such holder shall be made with respect
     to the rights and  interests of such holder to the end that the  provisions
     hereof (including,  without  limitation,  provisions for adjustments of the
     Conversion Price and of the number of shares  receivable upon the exercise)
     shall thereafter be applicable,  as nearly as possible,  in relation to any
     shares of capital stock,  securities or assets thereafter  deliverable upon
     the exercise of this Note.

         5.5.2 In the event of a merger,  share exchange or consolidation of the
     Company with or into another Person as a result of which a number of shares
     of common stock or its equivalent of the successor Person greater or lesser
     than the number of shares of Common Stock outstanding  immediately prior to
     such merger,  share  exchange or  consolidation  are issuable to holders of
     Common Stock, then the Conversion Price in effect immediately prior to such
     merger,  share  exchange  or  consolidation  shall be  adjusted in the same
     manner as though there were a subdivision or combination of the outstanding
     shares of Common Stock.

         5.5.3 The  Company  shall not  effect any such  consolidation,  merger,
     share  exchange,  sale,  transfer or other  disposition  unless prior to or
     simultaneously with the consummation thereof the successor Person (if other
     than the Company)  resulting  from such  consolidation,  share  exchange or
     merger or the Person  purchasing or otherwise  acquiring  such assets shall
     have assumed by written instrument  executed and mailed or delivered to the
     Holder hereof at the last address of such Holder  appearing on the books of
     the Company the obligation to deliver to such Holder such shares of capital
     stock,   securities  or  assets  as,  in  accordance   with  the  foregoing
     provisions,  such  Holder  may  be  entitled  to  receive,  and  all  other
     liabilities and obligations of the Company hereunder.  Upon written request
     by the Holder hereof,  such Successor  Person will issue a new Note revised
     to reflect the modifications in this Note effected pursuant to this Section
     5.5.

         5.5.4 If a purchase,  tender or exchange  offer is made to and accepted
     by the holders of 50% or more of the  outstanding  shares of Common  Stock,
     the Company shall not effect any consolidation,  merger,  share exchange or
     sale,  transfer or other  disposition  of all or  substantially  all of the
     Company's  assets  with  the  Person  having  made  such  offer or with any
     affiliate  of  such  Person,  unless  prior  to the  consummation  of  such
     consolidation,  merger, share exchange, sale, transfer or other disposition
     the holder  hereof shall have been given a reasonable  opportunity  to then
     elect to receive upon the conversion of this Note either the capital stock,
     securities  or assets then issuable with respect to the Common Stock or the
     capital stock, securities or assets, or the equivalent,  issued to previous
     holders of the Common Stock in accordance with such offer.

     5.6 Adjustment for Asset  Distribution.  If the Company declares a dividend
or other  distribution  payable  to all  holders  of shares  of Common  Stock in
evidences  of  indebtedness  of the  Company  or  other  assets  of the  Company
(including,  cash (other than  regular cash  dividends  declared by the Board of
Directors),  capital stock (other than Common Stock,  Convertible  Securities or
options or rights thereto) or other  property),  the Conversion  Price in effect
immediately  prior to 

<PAGE>

such declaration of such dividend or other  distribution  shall be reduced by an
amount equal to the amount of such dividend or distribution payable per share of
Common  Stock,  in the case of a cash dividend or  distribution,  or by the fair
value of such dividend or distribution  per share of Common Stock (as reasonably
determined in good faith by the Board of Directors of the Company),  in the case
of any other dividend or distribution. Such reduction shall be made whenever any
such dividend or  distribution  is made and shall be effective as of the date as
of which a record is taken for purpose of such dividend or distribution or, if a
record is not  taken,  the date as of which  holders  of record of Common  Stock
entitled to such dividend or distribution are determined.

     5.7 De Minimis Adjustments. No adjustment in the number of shares of Common
Stock  purchasable  hereunder  shall be required  unless such  adjustment  would
require  an  increase  or  decrease  of at  least  one  share  of  Common  Stock
purchasable  upon  conversion of the Note and no  adjustment  in the  Conversion
Price shall be  required  unless such  adjustment  would  require an increase or
decrease of at least $.01 in the Conversion Price;  provided,  however, that any
adjustments  which by reason of this  Section  5.7 are not  required  to be made
shall be carried  forward and taken into account in any  subsequent  adjustment.
All  calculations  shall  be made to the  nearest  full  share  or  nearest  one
hundredth of a dollar, as applicable.

     5.8 Notice of Adjustment.  Whenever the  Conversion  Price or the number of
Shares  issuable  upon the  conversion  of the Note shall be  adjusted as herein
provided,  or the rights of the holder  hereof  shall  change by reason of other
events specified herein, the Company shall compute the adjusted Conversion Price
and the adjusted number of Shares in accordance  with the provisions  hereof and
shall prepare an Officer's  Certificate  setting  forth the adjusted  Conversion
Price and the adjusted  number of Shares  issuable  upon the  conversion of this
Note or specifying the other shares of stock, securities or assets receivable as
a result of such change in rights,  and showing in  reasonable  detail the facts
and  calculations  upon which such  adjustments or other changes are based.  The
Company shall cause to be mailed to the Holder  hereof copies of such  Officer's
Certificate  together with a notice  stating that the  Conversion  Price and the
number of Shares purchasable upon conversion of this Note have been adjusted and
setting forth the adjusted  Conversion  Price and the adjusted  number of Shares
purchasable upon conversion of this Note.

     5.9 Notifications to Holder. In case at any time the Company proposes:

              (i) to  declare  any  dividend  upon its Common  Stock  payable in
         capital stock or make any special dividend or other distribution (other
         than cash dividends) to the holders of its Common Stock;

              (ii) to offer for  subscription  pro rata to all of the holders of
         its Common Stock any additional shares of capital stock of any class or
         other rights;

              (iii) to effect any capital reorganization, or reclassification of
         the capital  stock of the Company,  or  consolidation,  merger or share
         exchange of the Company 

<PAGE>

         with another Person,  or sale,  transfer or other disposition of all or
         substantially all of its assets; or

              (iv) to effect a voluntary or involuntary dissolution, liquidation
         or winding up of the Company,

then, in any one or more of such cases, the Company shall give the holder hereof
(a) at least 10 days (but not more  than 90 days)  prior  written  notice of the
date on which the books of the Company  shall  close or a record  shall be taken
for such dividend, distribution or subscription rights or for determining rights
to vote in  respect  of any  such  issuance,  reorganization,  reclassification,
consolidation, merger, share exchange, sale, transfer, disposition, dissolution,
liquidation  or  winding  up,  and  (b)  in  the  case  of  any  such  issuance,
reorganization,  reclassification,  consolidation, merger, share exchange, sale,
transfer, disposition,  dissolution, liquidation or winding up, at least 10 days
(but not more than 90 days) prior written notice of the date when the same shall
take place.  Such notice in accordance with the foregoing  clause (a) shall also
specify, in the case of any such dividend,  distribution or subscription rights,
the date on which the holders of Common  Stock shall be  entitled  thereto,  and
such notice in accordance  with the foregoing  clause (b) shall also specify the
date on which the holders of Common  Stock  shall be entitled to exchange  their
Common Stock,  as the case may be, for securities or other property  deliverable
upon  such  reorganization,   reclassification,   consolidation,  merger,  share
exchange, sale, transfer, disposition,  dissolution,  liquidation or winding up,
as the case may be.

     5.10 Company to Prevent  Dilution.  If any event or condition  occurs as to
which  other  provisions  of this  Article  are not  strictly  applicable  or if
strictly  applicable would not fairly protect the exercise or purchase rights of
this  Note  evidenced  hereby  in  accordance  with  the  essential  intent  and
principles of such provisions, or that might materially and adversely affect the
exercise or purchase  rights of the holder  hereof under any  provisions of this
Note,  then the Company shall make such  adjustments in the  application of such
provisions,  in accordance with such essential  intent and principles,  so as to
protect such  exercise and purchase  rights as  aforesaid,  and any  adjustments
necessary  with  respect  to the  Conversion  Price  and the  number  of  shares
purchasable  hereunder so as to preserve the rights of the holder hereunder.  In
no event shall any such  adjustment have the effect of increasing the Conversion
Price as otherwise  determined pursuant to this Article except in the event of a
combination of shares of the type  contemplated in Section 5.4 hereof,  and then
in no event to an amount greater than the Conversion Price as adjusted  pursuant
to Section 5.4 hereof.

                                   ARTICLE VI

                                    COVENANTS

     The Company covenants and agrees that, so long as this Note is outstanding:

     6.1 Payment of Principal  and Accrued  Interest.  The Company will duly and
punctually pay or cause to be paid the principal sum of this Note, together with
interest  accrued  thereon  from the date  hereof  to the  date of  payment,  in

to, do or cause to be done all things  necessary  to  preserve  and keep in full
force and effect its corporate  existence,  rights  (charter and  statutory) and
franchises;  provided,  however,  that the Company or a Subsidiary  shall not be
required  to  preserve  any such  right  or  franchise  if it  shall  reasonably
determine that the preservation thereof is no longer desirable in the conduct of
its business.

     6.3 Taxes;  Claims;  etc. The Company will, and will cause each  Subsidiary
to, promptly pay and discharge all lawful taxes,  assessments,  and governmental
charges or levies imposed upon it or upon its income or profits,  or upon any of
its  properties,  real,  personal,  or mixed,  before the same  shall  become in
default,  as well as all lawful  claims for labor,  materials,  and  supplies or
otherwise  which, if unpaid,  might become a lien or charge upon such properties
or any part  thereof,  and which  lien or charge  will have a  material  adverse
effect on the  business of the  Company;  provided,  however,  that  neither the
Company nor any Subsidiary shall be required to pay or cause to be paid any such
tax,  assessment,  charge,  levy, or claim prior to  institution  of foreclosure
proceedings  if the validity  thereof  shall  concurrently  be contested in good
faith by  appropriate  proceedings  and if the  Company  shall have  established
reserves  deemed by the Company  adequate with respect to such tax,  assessment,
charge, levy, or claim.

     6.4  Maintenance  of Existence and  Properties.  The Company will, and will
cause each Subsidiary to, keep its material  properties in good repair,  working
order,  and  condition,  ordinary wear and tear  excepted,  so that the business
carried on may be properly  conducted  at all times in  accordance  with prudent
business management.

     6.5 SEC  Reports.  The Company  will  deliver to the Holder  within 20 days
after it files them with the SEC, copies of its annual and quarterly reports and
of the information,  documents, and other reports (or copies of such portions of
any of the foregoing as the SEC may by rules and  regulations  prescribe)  which
the Company is required or elects to file with the SEC pursuant to Section 13 or
15(d) of the  Securities  Exchange Act of 1934.  The Company will timely  comply
with  its  reporting  and  filing   obligations  under  the  applicable  federal
securities laws.

     6.6 Notice of  Defaults.  The Company  will  promptly  notify the Holder in
writing of the  occurrence of (i) any Event of Default under this Note, and (ii)
any event of default (or if any event 


<PAGE>

of default would result upon any payment with respect to this Note) with respect
to any  Indebtedness  as such  event of  default  is  defined  therein or in the
instrument under which it is outstanding,  permitting  holders to accelerate the
maturity of such Indebtedness.

     6.7 Compliance  with Laws. The Company will promptly  comply with all laws,
ordinances and  governmental  rules and regulations to which it is subject,  the
violation of which would materially and adversely affect the Company.

     6.8 Amendments to Charter. The Company will not amend or modify its charter
without the prior written consent of Holder.

     6.9 Mergers  and  Acquisitions.  Without  the  consent of the  Holder,  the
Company or any Subsidiary will not dissolve,  liquidate,  consolidate,  merge or
enter  into a share  exchange  with or sell  or  transfer  all or a  substantial
portion of its assets to any Person.

                                   ARTICLE VII

                                  MISCELLANEOUS

     7.1 Consent to  Amendments.  This Note may be amended,  and the Company may
take any action herein prohibited, or omit to perform any act herein required to
be performed by it, if and only if the Company shall obtain the written  consent
to such  amendment,  action or omission to act from the holders of a majority of
the aggregate principal amount of this Note.

     7.2  Benefits  of Note;  No  Impairment  of  Rights  of  Holder  of  Senior
Indebtedness.  Nothing  in this  Note,  express  or  implied,  shall give to any
Person, other than the Company,  Holder, and their successors any benefit or any
legal or equitable right, remedy or claim under or in respect of this Note.

     7.3  Successors  and Assigns.  All  covenants  and  agreements in this Note
contained  by or on behalf of the Company and the Holder shall bind and inure to
the  benefit of the  respective  successors  and  assigns of the Company and the
Holder.

     7.4  Restrictions  on Transfer.  Holder shall not transfer this Note except
(by the grant of a  security  interest)  to its  lender or  lenders.  As between
Holder and its lender or lenders,  this Note is  transferable in the same manner
and with the same effect as in the case of a negotiable  instrument payable to a
specified person.  Any lender to which Holder grants a security interest in this
Note shall be  entitled  to  exercise  all  remedies  to which it is entitled by
contract or by law, including (without  limitation)  transferring this Note into
its own  name or into  the  name of any  purchaser  at any  sale  undertaken  in
connection with enforcement by such lender of its remedies.

     7.5  Notice;  Address  of  Parties.   Except  as  otherwise  provided,  all
communications to the Company or Holder provided for herein or with reference to

being sent as certified or registered mail, postage and charges prepaid,  to the
following  addresses:  if to the Company:  Black Warrior  Wireline  Corp.,  3748
Highway  #45  North,  Columbus,  Mississippi  39701,  or at  any  other  address
designated by the Company in writing to Holder;  if to Holder:  SJMB,  L.P., c/o
St. James Capital  Corp.,  777 Post Oak  Boulevard,  Suite 950,  Houston,  Texas
77056,  Attn:  Jay Brown,  or at any other  address  designated by Holder to the
Company in writing.

     7.6  Separability  Clause.  In case any  provision  in this  Note  shall be
invalid,  illegal or unenforceable in any jurisdiction,  the validity,  legality
and enforceability of the remaining provisions in such jurisdiction shall not in
any way be affected or impaired thereby;  provided,  however,  such construction
does not destroy the essence of the bargain provided for hereunder.

     7.7  Governing  Law.  This Note  shall be  governed  by, and  construed  in
accordance  with, the internal laws of the State of Delaware  (without regard to
principles of choice of law).

     7.8  Usury.  It is the intention of the parties hereto to conform  strictly
to the  applicable  laws of the  State of  Delaware  and the  United  States  of
America,  and  judicial  or  administrative  interpretations  or  determinations
thereof  regarding the contracting  for,  charging and receiving of interest for
the use,  forbearance,  and detention of money (hereinafter  referred to in this
Section 7.8 as "Applicable  Law").  The Holder shall have no right to claim,  to
charge or to receive any interest in excess of the maximum rate of interest,  if
any,  permitted  to be  charged  on  that  portion  of the  amount  representing
principal  which is outstanding  and unpaid from time to time by Applicable Law.
Determination  of the rate of interest  for the purpose of  determining  whether
this  Note is  usurious  under  Applicable  Law  shall  be  made by  amortizing,
prorating,  allocating  and  spreading  in equal parts  during the period of the
actual  time of this Note,  all  interest  or other sums  deemed to be  interest
(hereinafter  referred  to in  this  Section  7.8 as  "Interest")  at  any  time
contracted  for,  charged or received from the Company in  connection  with this
Note. Any Interest  contracted for, charged or received in excess of the maximum
rate allowed by Applicable Law shall be deemed a result of a mathematical  error
and a mistake.  If this Note is paid in part prior to the end of the full stated
term of this Note and the Interest  received for the actual  period of existence
of this Note exceeds the maximum rate allowed by  Applicable  Law,  Holder shall
credit the amount of the excess  against any amount owing under this Note or, if
this Note has been paid in full,  or in the event  that it has been  accelerated
prior to maturity, Holder shall refund to the Company the amount of such excess,
and shall not be subject to any of the penalties  provided by Applicable Law for
contracting  for,  charging or receiving  Interest in excess of the maximum rate
allowed by Applicable Law. Any such excess which is unpaid shall be canceled.
