                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)


  1. Interim  Financial  Statement

     The  balance  sheet  as of May 31,  1999,  and the  related  statements  of
     operations  for the three and six month periods ended May 31, 1999 and 1998
     and the  statements  of cash flows for the six month  periods ended May 31,
     1999 and 1998 are unaudited; in the opinion of management,  all adjustments
     necessary for a fair  presentation  of such financial  statements have been
     included.  These financial  statements and notes are presented as permitted
     by Form  10-QSB  and  should  be read in  conjunction  with  the  Company's
     financial  statements  and  notes  included  in the  annual  report on Form
     10-KSB.

  2. Earnings Per Share

     The Company has adopted FAS 128. FAS 128 requires a  reconciliation  of the
     numerators  and  denominators  of the basic and diluted  EPS  computations.
     Options to purchase  354,584 and 210,894 shares of common stock at weighted
     average prices of $6.43 and $6.67 were  outstanding  during the three month
     and six month  periods ended May 31, 1999 and 1998  respectively,  but were
     not included in the  computation of diluted EPS because the effect of these
     outstanding  options would be antidilutive.  During the three and six month
     periods  ended  May 31,  1999  and  1998,  respectively,  the  Company  had
     outstanding  $6,000,000 of convertible  debentures which could be converted
     into common stock at a price of $8.75 per share.  These securities were not
     included  in  the   computation  of  diluted  EPS  because  they  would  be
     antidilutive.

  3. Sale of Rental  Operations

     In  December  1998,  the  company  consummated  the sale of its  industrial
     cooling tower rental operations (the "Rental  Operations") to Aggreko Inc.,
     an unrelated  party,  for  $13,500,000,  with  $12,150,000  paid in cash at
     closing and the  remaining  $1,350,000  paid by delivery of Aggreko  Inc.'s
     promissory  note (the "Note").  The Note bears  interest at 1% above prime.
     The  outstanding  principal  balance  of the Note,  together  with  accrued
     interest, is due and payable in December 1999. The assets sold included the
     modular  cooling  tower rental  fleet,  other rental fleet  equipment,  and
     certain assets used in the operation of the Rental Operations. Accordingly,
     the Company  recorded a pre-tax  gain of  $6,688,670  for the three  months
     ended February 28, 1999.  Proceeds were used to reduce debt and for working
     capital.  In connection with the sale of assets  described  above,  Aggreko
     Inc.,  the Company,  and Harold D. Curtis,  The Company's  Chief  Executive
     Officer,  entered  into  a  Noncompetition  Agreement.  The  Noncompetition
     Agreement  generally  prohibits the Company and Mr. Curtis from  conducting
     any business in competition with the Rental  Operations,  as well as hiring
     certain  of  the  Company's  prior  employees  who  worked  in  the  Rental
     Operations.  Additionally,  in connection with the sale of assets described
     above, the Company and Aggreko Inc. entered into a License  Agreement and a
     Supply Agreement. The License Agreement grants to Aggreko Inc. an exclusive
     license to use for a limited  time period the  patents,  trademarks,  trade
     names and other proprietary  rights related to the Rental  Operations.  The
     Supply  Agreement  describes the terms upon which the Company has agreed to
     sell to Aggreko  Inc.,  and Aggreko  Inc.  has agreed to purchase  from the
     Company,  all modular cooling tower units and  replacement  parts necessary
     for future operations of the Rental Operations. F-5

  4. Debt

    In April  1999,  the Company  increased  its line of credit with a financial
    institution from $4,000,000 to $6,500,000 for working capital  requirements.
    Interest is payable  monthly at a variable rate of 2.0% over national prime.
    This line of credit  matures on April 30,  2000.  This  credit  facility  is
    collateralized by certain accounts/notes  receivable,  inventory and general
    intangibles  and  as of  May  31,  1999,  $5,060,811  was  outstanding.  The
    agreement contains a financial covenant that provides for a minimum tangible
    net  worth  of  $12,000,000  for  the  first  three  quarters  of  1999  and
    $14,000,000 for the year-end November 30, 1999.  Tangible net worth includes
    the $6,000,000 of subordinated convertible debentures.

  5. Acquisition and Dissolution of Joint Venture

    On December 29, 1995, Tower Tech entered into a joint venture agreement with
    J-Tech  Enterprises,  Inc.  ("J-Tech")  to form Tower Tech SE ("TTSE").  The
    original joint venture gave TTSE the sole and exclusive right to use certain
    Tower Tech technology in Alabama, Florida, and Georgia.

    On  April  30,  1999,  Tower  Tech  entered  into an  agreement  and plan of
    dissolution to acquire J-Tech's interest and dissolve the joint venture. The
    aggregate  purchase  price of $430,677 was comprised of $100,000 in cash and
    $330,677 of net  receivables  owed to the  Company by TTSE.  Tower Tech also
    received all cash, accounts  receivable,  inventory,  accounts payable,  and
    other current  liabilities of TTSE. The transaction  resulted in goodwill to
    Tower Tech of $398,200,  which will be amortized  on a  straight-line  basis
    over its estimated useful life.

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


   Three Months Ended May 31, 1999 Compared to Three Months Ended May 31, 1998

     Total tower  revenues  were  $4,674,142  for the three months ended May 31,
1999,  compared to $5,865,233  in the same period in the prior year.  During the
current three month period,  77 percent of total tower revenues was derived from
sales of 114 modular factory assembled cooling towers, 18 percent of total tower
revenues was derived from design and  construction of modular  concrete  towers,
and 5 percent of total tower  revenues was derived from other  revenues.  In the
comparable  three month period of 1998,  43 percent of total tower  revenues was
derived from sales of 77 modular factory assembled cooling towers, 41 percent of
total tower revenues was derived from  construction of modular  concrete towers,
12 percent of total tower  revenues was derived  from rental of modular  cooling
towers,  and 4 percent of total  tower  revenues  was  derived  from other tower
revenues. Other tower revenues consist primarily of sales of modular tower parts
and service,  accessory equipment and water treatment equipment. The increase in
factory assembled tower sales for 1999 is due to the increase in the quantity of
units sold.  Such  increase is due to marketing  efforts for the newly  designed
TTEF  Series  tower and a selling  price  reduction  made  possible  because  of
significant completion of the manufacturing  processes for TTEF Series component
parts at the OKC  facility.  The  decrease  in  concrete  revenues is due to the
decrease in the number and size of jobs completed and in process.  For the three
months ended May 31, 1998,  33% of concrete  tower sales was generated  from two
international  projects  as  compared  to  no  international  projects  for  the
three-months ended May 31, 1999. However,  the Company has seen some improvement
in certain international markets with recent orders from Mexico, Brazil, Austria
and Singapore for concrete cooling tower projects and factory  assembled cooling
towers. The Company has restructured its pricing on its precast concrete cooling
tower and has redesigned  certain  proprietary  parts which management  believes
will lower costs as well as increase thermal  capability of its concrete cooling
tower.  Management is optimistic  that concrete tower revenues will improve with
continued  improvement in the international  market economies,  and domestically
with aggressive  marketing of its redesigned  precast  concrete  cooling towers.
Decreased  tower  rentals is due to the sale of the rental  operations  as below
described.  No licensing agreements were finalized in the second quarter of 1999
although discussions are continuing for agreements for Spain, Peru, New Zealand,
Australia, and the United Kingdom.

     The  Company's  cost of goods sold and  constructed  during the three month
period  ended  May 31,  1999,  was  $4,868,437  or 104  percent  of total  tower
revenues, as compared to $5,712,658 or 97 percent of total tower revenues during
the  comparable  period  in  1998.  The  decrease  in cost  of  goods  sold  and
constructed  during the second  quarter of 1999 resulted  mainly from  decreased
sales of  concrete  cooling  towers.  Overall  margin  decreased  as a result of
concrete  cooling  tower cost  overruns on certain  jobs,  and  decreased  tower
rentals which carried a higher  margin.  In an effort to control costs on future
concrete cooling tower projects, the Company will utilize precast panels in lieu
of  "tilt-up" on site  construction.  Slightly  improved  margins in the factory
assembled cooling tower line continue to be hampered by the refinements required
for completion of the manufacturing  processes,  equipment,  and tooling.  It is
estimated  that these  refinements  will  continue to have a negative,  although
lessening, impact on third quarter 1999 margins and operations.

         Included  in the cost of  goods  sold for the  second  quarter  1999 is
$306,023 to retrofit  and  service  towers  previously  sold.  This  compares to
expenditures  of  $87,234  during  the  comparable  period  in the  prior  year.
Approximately  60% of the increase is due to retrofit and service costs incurred
on  certain  concrete  towers.  Management  does not  expect  these  costs to be
recurring.










                                       -3-


<PAGE>



         The three  month  period  ended May 31,  1999  reflected  a 16  percent
decrease  in  general  and  administrative  expenses  from  $629,600  in 1998 to
$526,317 in 1999. The decrease is due to a reduction in expenses  related to the
OKC facility and a reduction of $60,000 in bad debt expenses.  Selling  expenses
decreased  from  $462,885 to $375,895  due to a  reduction  in expenses  related
primarily to the opening of direct domestic and  international  sales offices in
1998.  Research and development  expenses  increased from $112,787 in the second
quarter of 1998 to $431,678 in the second quarter of 1999. A significant portion
of the  increase  in R & D costs is related to the  redesign  of the TTMT Series
tower to the TTEF  Series  tower in order to lower  production  costs.  With the
redesign of the tower combined with  manufacturing  of component parts in-house,
management  believes that the Company has positioned itself to grow its share of
the cooling tower market. With the lower expected  production costs,  management
believes that it will be able to lower prices to its customers  and, at the same
time,  increase margins.  Management  expects to continue to conduct research to
develop  refinements  in cooling  tower  design and  construction.  Although the
Company has no fixed  research  and  development  budget,  such future costs are
anticipated to be less than current expenditures.

         The Company's  loss from  operations for the three months ended May 31,
1999 was $1,528,185 as compared to a loss from  operations of $1,052,697 for the
comparable  period in the prior  year.  After  interest  expense,  miscellaneous
items, and income tax benefit, the Company's net loss was $1,224,495 compared to
a net loss of $754,358 for the quarter ended May 31, 1998.

         Interest expense increased from $248,182 for the three months ended May
31, 1998 to $562,025 for the three  months  ended May 31, 1999.  The increase is
due to the increase in debt related primarily to the OKC manufacturing  facility
and  equipment and the fact that  interest on such debt was  capitalized  during
1998.

         The Company  recognized an income tax benefit of $817,060 for the three
months ended May 31, 1999, compared to an income tax benefit of $502,905 for the
comparable  period in 1998. The ultimate  realization of the deferred income tax
assets at May 31, 1999 depends on the Company's  ability to generate  sufficient
taxable income in the future.  Management has determined  that it is more likely
than not that the Company will realize the deferred tax assets.

         Currently, the estimated backlog is $5.9 million including one contract
for the modular  concrete  cooling tower  totaling $.9 million.  This project is
scheduled for  completion  in fourth  quarter  1999.  Estimated  backlog for the
factory assembled cooling towers is $5.0 million.  $4.2 million is scheduled for
delivery in the third quarter 1999,  with the balance  scheduled for delivery in
the fourth quarter of 1999.


     Six Months Ended May 31, 1999 Compared to Six Months Ended May 31, 1998

         For the six months ended May 31, 1999,  total tower revenues  decreased
to  $9,009,245  from  $9,915,823  for the  comparable  period in the prior year.
During the current six month  period,  82 percent of total  tower  revenues  was
derived from sales of 236 modular factory  assembled  cooling towers, 12 percent
of total  tower  revenues  was derived  from  construction  of modular  concrete
cooling  towers,  less than 1 percent of total tower  revenues  was derived from
rental of  modular  fiberglass  cooling  towers,  and 5 percent  of total  tower
revenues  was derived  from other tower  revenue.  In the  comparable  six month
period in 1998, 41 percent of total tower revenues was derived from sales of 118
modular factory assembled cooling towers, 44 percent of total tower revenues was
derived from  construction of modular concrete towers, 12 percent of total tower
revenues was derived  from rental of modular  cooling  towers,  and 3 percent of
total tower  revenues  were  derived from other tower  revenue.  The increase in
factory assembled tower sales for 1999 is due to the increase in the quantity of
units sold.  Such  increase is due to marketing  efforts for the newly  designed
TTEF  Series  tower and a selling  price  reduction  made  possible  because  of
significant completion of the manufacturing  processes for TTEF Series component
parts at the OKC  facility.  The  decrease  in  concrete  revenues is due to the
decrease in the number and size of jobs  completed  and in process.  For the six
months ended May 31, 1998,  46% of concrete  tower sales was generated  from two
international  projects  as compared to no  international  projects  for the six
months ended May 31,  1999.  Decreased  tower  rentals is due to the sale of the
rental  operations  as  below  discussed.  Other  tower  revenue  is up from the
previous year due to the same reasons that tower sales  increased.  No licensing
agreements were finalized in the first six months of 1999 although  negotiations
are continuing for agreements for Spain, Peru, New Zealand,  Australia,  and the
United Kingdom.


                                       -4-

         In December  1998, the company  consummated  the sale of its industrial
cooling tower rental  operations  (the "Rental  Operations") to Aggreko Inc., an
unrelated party,  for $13,500,000,  with $12,150,000 paid in cash at closing and
the remaining $1,350,000 paid by delivery of Aggreko Inc.'s promissory note (the
"Note").  The Note bears interest at 1% above prime.  The outstanding  principal
balance of the Note,  together  with  accrued  interest,  is due and  payable in
December 1999. The assets sold included the modular  cooling tower rental fleet,
other rental fleet  equipment,  and certain  assets used in the operation of the
Rental  Operations.   Accordingly,  the  Company  recorded  a  pre-tax  gain  of
$6,688,670 for the three months ended  February 28, 1999.  Proceeds were used to
reduce debt and for working capital.

         In connection with the sale of assets  described  above,  Aggreko Inc.,
the Company,  and Harold D.  Curtis,  the  Company's  Chief  Executive  Officer,
entered into a Noncompetition  Agreement. The Noncompetition Agreement generally
prohibits the Company and Mr. Curtis from conducting any business in competition
with the Rental  Operations,  as well as hiring  certain of the Company's  prior
employees who worked in the Rental Operations.

         Additionally,  in connection with the sale of assets  described  above,
the Company and  Aggreko  Inc.  entered  into a License  Agreement  and a Supply
Agreement.  The License Agreement grants to Aggreko Inc. an exclusive license to
use for a limited  time period the  patents,  trademarks,  trade names and other
proprietary  rights  related to the  Rental  Operations.  The  Supply  Agreement
describes  the terms upon which the Company has agreed to sell to Aggreko  Inc.,
and Aggreko Inc. has agreed to purchase  from the Company,  all modular  cooling
tower units and replacement  parts necessary for future operations of the Rental
Operations.

         The Company's cost of goods sold and  constructed  during the six month
period ended May 31, 1999, was $9,355,174 or 104 percent of total tower revenues
as compared to $9,121,219 or 92 percent  during the  comparable  period in 1998.
The increase in cost of goods sold and constructed for the six months ending May
31, 1999 resulted from the increase in tower sales.  Overall margin decreased as
a result of concrete  cooling tower cost overruns on certain jobs, lower margins
incurred in the  factory  assembled  cooling  tower line,  and  decreased  tower
rentals  which carry a higher  margin.  Lower  margins in the factory  assembled
cooling tower line are due to the delays in the  completion and occupancy of the
Oklahoma  City  (OKC)  plant  combined  with  delays  in  the  delivery  of  the
manufacturing  equipment  and tooling for the first  three  months of 1999,  and
continued   refinements   required  for  the  completion  of  the  manufacturing
processes,  equipment,  and tooling for the second three  months of 1999.  It is
estimated  that these  refinements  will  continue to have a negative,  although
lessening, impact on third quarter 1999 margins and operations. Included in cost
of goods  sold for the six month  period  ended May 31,  1999,  is  $453,608  to
retrofit and service towers previously sold. This compares to six month retrofit
and service costs of $172,234 during the same period in 1998.  Approximately 60%
of the  increase  is due to  retrofit  and  service  costs  incurred  on certain
concrete  towers.  Management  does  not  expect  these  increased  costs  to be
recurring.

         The six month period ended May 31, 1999 reflected a 5 percent  decrease
in general and administrative  expenses from $1,074,304 in 1998 to $1,018,006 in
1999. The decrease is due mainly to the reduction in expenses related to the OKC
facility.  Selling expenses decreased from $888,350 to $739,368. The decrease is
due to a  reduction  in  expenses  related  primarily  to the  opening of direct
domestic and  international  sales  offices in 1998.  Research  and  development
expenses  increased from $195,171 in the first six months of 1998 to $877,575 in
the first six months of 1999.  A  significant  portion of the  increase in R & D
costs is related to the  redesign  of the TTMT  Series  tower to the TTEF Series
tower in order  to lower  production  costs.  With  the  redesign  of the  tower
combined with  manufacturing  of component parts in-house,  management  believes
that the Company has  positioned  itself to grow its share of the cooling  tower
market.  With the expected lower production costs,  management  believes that it
will be able to lower prices to its  customers  and, at the same time,  increase
margins.   Management  expects  to  continue  to  conduct  research  to  develop
refinements in cooling tower design and  construction.  Although the Company has
no fixed research and development  budget,  such future costs are anticipated to
be less than current expenditures.

         The  Company's  loss from  operations  for the six months ended May 31,
1999, was  $2,980,878 as compared to loss from  operations of $1,363,221 for the
comparable  period in the prior  year.  After  interest  expense,  miscellaneous
items, gain on sale of rental operations and income tax (expense)  benefit,  the
Company's net income was $1,652,501 compared to a net loss of $1,051,693 for the
six months ended May 31, 1998.

         Interest  expense  increased from $460,607 for the six months ended May
31, 1998 to  $1,068,721  for the six months ended May 31, 1999.  The increase is
due to the increase in debt related primarily to the OKC manufacturing  facility
and  equipment and the fact that  interest on such debt was  capitalized  during
1998.

         The Company  recognized an income tax expense of $1,101,880 for the six
months ended May 31, 1999, compared to an income tax benefit of $701,128 for the
comparable  period in 1998. The ultimate  realization of the deferred income tax
assets at May 31, 1999 depends on the Company's  ability to generate  sufficient
taxable income in the future.  Management has determined  that it is more likely
than not that the Company will realize the deferred tax assets.


Liquidity and Capital Resources

       At May 31,  1999,  the  Company  had  working  capital of  $2,030,271  as
compared to a working  capital  deficit of $3,890,374 at November 30, 1998.  The
Company's cash flow provided by (used in) its operating, investing and financing
activities for the six months ended May 31, 1999 and 1998 are as follows:

                                     1999                          1998
                                     ----                          ----

        Operating activities     ($5,644,947)                   $1,328,375
        Investing activities     $10,147,049                   ($7,472,120)
        Financing activities     ($4,326,112)                   $5,916,984


       The Company's capital requirements for its continuing  operations consist
of its general working capital needs, scheduled payments on its debt obligations
and  capital  expenditures.  The  Company  tries to minimize  its  inventory  of
component parts, although minimum order requirements of some suppliers can cause
inventory  levels to  fluctuate  significantly  from period to period.  Although
bringing the manufacturing  processes in-house has taken over a year longer than
expected and has cost  substantially  more than anticipated,  it will enable the
Company  to  better  manage  inventory  levels  and  reduce  costs  when the new
manufacturing  facility is fully efficient.  However,  fluctuations in inventory
levels  are  still  expected  due to the  size  of  planned  production  runs of
components.  Management also attempts to manage accounts  receivable to increase
cash flow, but it is anticipated that accounts receivable will increase as sales
increase.  Other  significant  variances  in working  capital  items can also be
expected.  Also, the Company's concrete cooling tower projects have an effect on
working capital  requirements.  At May 31, 1999, costs and estimated earnings in
excess of billings on  uncompleted  contracts were $148,166 as compared to costs
and  estimated  earnings  in excess of  billings  on  uncompleted  contracts  of
$1,900,662 at May 31, 1998.  Normally,  concrete  cooling tower projects provide
for progress payments of the contract price with a retainage of 10 to 15 percent
payable after completion of the project.

       Scheduled  principal  payments on capital leases will total $132,680 over
the next twelve  months.  In addition,  $6,325,953  of principal  payments  will
become due on the Company's debt during the next twelve months.

     Substantially all of the Company's planned capital  expenditures during the
remainder of 1999 will be related to  additional  equipment  and tooling for the
new manufacturing facility.  Management estimates the Company's total investment
in the new manufacturing facility will be $13.5 million,  including $7.2 million
to  equip  the  facility.   As  of  May  31,  1999,  the  Company  had  incurred
approximately   $10  million  related  to  the   manufacturing   facility.   The
manufacturing  facility includes equipment to allow the Company to produce parts
used in the modular  cooling  towers which  previously  had been  purchased from
outside  vendors.  Management  believes  that  product  costs can be  reduced by
producing  these parts  in-house.  However,  the  Company may  continue to incur
unforeseen  costs and production  problems,  particularly  in the short term, in
bringing these processes in-house.






                                       -6-

       The new  manufacturing  facility has been partially  financed with a $4.4
million loan from the Oklahoma Industries Authority (the "OIA") and a portion of
the proceeds of a private placement of $6 million, 10% Convertible  Subordinated
Debentures (the  "Debentures").  The industrial revenue bonds were issued by the
OIA in  October  1996.  The bonds  are  payable  in  quarterly  installments  of
principal and interest in the amount of approximately  $157,000.  A debt service
reserve  fund of  $157,000  was also set aside from the bond  proceeds.  The OIA
holds a mortgage on the facility to collateralize the bond indebtedness.

       The  Debentures  were issued by the Company  during the third  quarter of
1997,  providing net proceeds of approximately  $5,467,000.  The Debentures bear
interest at 10 percent,  which is payable  semiannually,  and mature on June 30,
2000.  The principal  balance of each  Debenture is  convertible  into shares of
common  stock at a price of $8.75  per  share at the  option  of each  Debenture
holder or at the option of the Company if the closing  price of the common stock
is at least 175% of the conversion  price for 20 of 30 consecutive  trading days
and certain other conditions are satisfied.

       In September  1997,  the Company  entered into a loan  agreement with the
City of  Oklahoma  City in the form of a HUD  Section  108 loan in the amount of
$1,250,000 for start-up  expenses of the  manufacturing  facility and associated
working  capital  requirements.  As of May 31, 1999, all of these funds had been
advanced to the Company. The loan bears interest at 5.5% and interest is payable
August  1, 1999 and each  February  1,  thereafter.  Thereafter,  principal  and
interest payments are due annually August 1 in the amount of $140,000.  The loan
is collateralized by a second mortgage on the manufacturing facility.

       The Company has entered into an agreement with a lending  institution for
a  total  funding  of   $1,775,815   for  equipment  and  tooling  for  the  new
manufacturing  facility.  Principal and interest, at 9.25%, is paid monthly with
the final  payment  due in July 2004 and is  collateralized  by  equipment.  The
outstanding balance at May 31, 1999, was $1,563,804.

       Effective  December 31, 1997, the Company  entered into a $3,500,000 line
of  credit   agreement  with  a  financial   institution   for  working  capital
requirements and completion of the Company's  manufacturing facility in Oklahoma
City.  This line was  increased  to  $8,500,000  to help fund  increases  in the
Company's rental fleet.  This credit facility was paid off in December 1998 with
proceeds from the sale of the rental operations.

       The  Company  has a line of credit  at  Chickasha  Bank in the  amount of
$400,000 for short-term  cash flow needs,  of which $400,000 was  outstanding at
May 31,  1999.  This line of credit  matures  August 31, 1999 and was reduced to
$380,000 subsequent to May 31, 1999.

       In April 1998, the Company  finalized a $2,000,000  construction loan for
the Oklahoma City office facility which cost approximately $2.4 million.  At May
31, 1999,  $1,999,937  was  outstanding.  This loan was converted to a permanent
loan in June  1999 in the  amount  of  $2,010,000.  Initially,  the  loan  bears
interest at 8.25%.  Principal and interest  payments of $17,127 are due monthly.
The note  matures in June 2002.  Also,  in June 1999,  a second  mortgage in the
amount of $253,000 was finalized.  Initially,  the loan bears interest at 8.25%.
Principal and interest  payments of $3,103 are due monthly.  The note matures in
June 2002. The interest rates on both of these notes are variable at Wall Street
Journal prime rate plus .5%.

       In December  1998, the Company  entered into a $4,000,000  line of credit
agreement with a financial  institution  for working  capital  requirements.  In
April 1999,  this line was increased to $6,500,000.  Interest is payable monthly
at a variable rate of 2.0% over national  prime.  This line of credit matures in
April 2000.  This credit  facility is  collateralized  by certain  accounts/note
receivable,  inventory  and  general  intangibles,  and  as  of  May  31,  1999,
$5,060,811 was outstanding. The Company is negotiating to extend the maturity of
the facility.

       On December 29, 1995,  Tower Tech entered into a joint venture  agreement
with J-Tech  Enterprises,  Inc.  ("J-Tech") to form Tower Tech SE ("TTSE").  The
original  joint  venture gave TTSE the sole and  exclusive  right to use certain
Tower Tech technology in Alabama, Florida, and Georgia.





                                       -7-


<PAGE>


          On April 30, 1999,  Tower Tech  entered into an agreement  and plan of
dissolution to acquire  J-Tech's  interest and dissolve the joint  venture.  The
aggregate  purchase  price of  $430,677  was  comprised  of $100,000 in cash and
$330,677  of net  receivables  owed to the  Company  by TTSE.  Tower  Tech  also
received all cash, accounts receivable,  inventory,  accounts payable, and other
current liabilities of TTSE. The transaction  resulted in goodwill to Tower Tech
of $398,200, which will be amortized on a straight-line basis over its estimated
useful life.

       The Company does not believe it has sufficient  capital resources to fund
its capital  requirements  for the next four  quarters.  Although the  Company's
financial  position has improved  from  November  30, 1998,  planned  growth and
continued operating losses have increased the Company's funding requirements and
require it to obtain  additional  capital to maintain  its growth.  Accordingly,
management is negotiating for increases in its credit  facilities and additional
sources of capital.  Management  recognizes that the Company is highly leveraged
and that while financial  leverage can increase the Company's  return on equity,
it also increases the risk presented to equity owners of the Company.

Year 2000 Compliance

       Approximately  two years ago the Company  developed a plan to address the
Year 2000 (Y2K) issue. The plan consists of the following steps and is ongoing:

- -- Testing of all computer equipment, plant production equipment, hardware
     and/or software.
- -- Upgrading or replacing, as needed, any component found to not be Y2K
     compliant.
- -- Contacting our vendors,  customers and business partners to ensure
     that they are also addressing the Y2K issue.
     And,  if any  are  found  to not be  addressing  the Y2K  issue,  establish
     alternative sources for those goods and/or services supplied by the non-Y2K
     compliant party.

       Accordingly,  the Company has  upgraded its  accounting  systems and main
application  software  to  the  latest  versions  available  from  the  software
developers at a cost of approximately  $100,000.  Each of these various software
developers  has stated  that the  version(s)  of  software  to which the Company
upgraded is or will be Y2K compliant.  Any computer equipment,  plant production
equipment,  hardware or software found to not be Y2K compliant has been, or will
be  upgraded  or  replaced  as needed in order to  insure  uninterrupted  normal
operation of production  and office  processes.  As a result of our Y2K plan and
information  furnished  to us by our  business  partners,  the Company  does not
expect to be materially affected by the Y2K problem.

Agreement   and   applicable   Loan   Documents,   and  in  reliance   upon  the

make the Loan in favor of the  Borrower,  which  shall be  available  during the
period from the Closing Date until June 1, 2000, and which may be drawn upon, in
whole or in part, by Advances from the Bank pursuant to paragraph 2.2.

                  The aggregate principal amount of all such Advances at any one
time outstanding  shall not exceed the lesser of (i) the Commitment (as the same
may be reduced by the Borrower  pursuant to paragraph 2.8) or (ii) the Borrowing
Base. The Loan shall be a revolving credit  facility,  and, subject to the terms
and  conditions  of this  Agreement,  the  Borrower  shall be  permitted to make
prepayments (as provided in paragraph 2.5) and reborrowings thereunder.

                  2.2     Advances on Loan.  All Advances on  the Loan shall be
subject to the following terms and conditions:

                            2.2.1   Use of  Proceeds.  Advances shall be used by

                  2.3 The Note.  The  Advances  made by the Bank  under the Loan
shall be evidenced by the Note,  which shall be made,  executed and delivered by
the Borrower at the Closing.  Notwithstanding the principal amount stated on the
face of the Note, the actual  principal  amount due from the Borrower on account
thereof  shall be the sum of all Advances  made by the Bank,  less all principal
payments actually received by the Bank in collected funds thereon.  All Advances
shall be  recorded  by the Bank on its books or at its  option  endorsed  on the
reverse  side of the Note,  and the  unpaid  principal  balance so  recorded  or
endorsed  shall be conclusive  evidence of the principal  amount owing  thereon,
absent manifest error.

                  2.4  Interest.

                            2.4.1  Rate.  The  unpaid  principal  amount  of all
         Advances on the Loan from time to time outstanding  shall bear interest
         prior to Default at a rate equal to the sum of two percent  (2.0%) plus
         the Base Rate.  Upon the occurrence of an Event of Default,  the unpaid
         principal  amount on all Advances from time to time  outstanding on the
         Notes shall bear interest at a rate equal to the greater of (i) the sum
         of eight  percent  (8.0%) plus the Base Rate,  or (ii) fifteen  percent
         (15%)  per  annum.  Interest  rate  changes  in the Base  Rate  will be
         effective on the day of the rate change,  without notice to Borrower or
         Guarantor.

                            2.4.2  Basis  of  Computation.   Interest  shall  be
         computed  for the actual  number of days elapsed on the basis of a year
         consisting of 360 days.

                           2.4.3  Payment Dates. Interest and principal payments
        on the Note shall be due and payable at the times specified in the Note.

                  2.5 Optional  Prepayments.  The Borrower may from time to time
prepay  the  outstanding  Advances  on the  Loan,  in whole or in part,  without
premium or penalty.

                  2.6  Mandatory  Prepayments.  If at  any  time  the  aggregate
principal  amount of all  outstanding  Advances  on the Loan  exceeds the amount
available  for  Advances,  as set forth in paragraph  2.1,  the  Borrower  shall
immediately  make a mandatory  prepayment on the Note to the extent necessary to
reduce the principal  balance  outstanding to the amount  specified in paragraph
2.1.

                  2.7 Making of Payments.  All payments,  including prepayments,
of principal of, or interest on, the Note shall be made in immediately available
funds by the Borrower to the Bank. Whenever a payment is due on a day other than
a Business Day, the due date shall be extended to the next  succeeding  Business
Day and interest (if any) shall accrue during such extension. All payments shall
be made to the Bank at its  principal  office in Oklahoma  City,  Oklahoma,  not
later than 2:00 p.m.,  Oklahoma City time,  on the date due, and funds  received
after  that hour shall be deemed to have been  received  by the Bank on its next
following Business Day.

     2.8  Reduction of  Commitment.  The Borrower  may, from time to time, on at
least  five (5)  Business  Days'  prior  written  notice  received  by the Bank,
permanently reduce the amount of the Commitment,  but only upon repayment of the
amount,  if  any,  by  which  the  aggregate  unpaid  principal  amount  of  all

                  2.9  Minimum  Advance  Outstanding  on the Loan.  At all times
during the term of this Agreement,  the Borrower will maintain a minimum Advance
of $10,000.00 on the Loan.

                  2.10 Renewal and  Extension.  In the event the Loan is renewed
and extended,  then the terms and provisions of this Agreement shall continue in
full  force and  effect,  except as may  otherwise  be agreed in  writing by the
Borrower and the Bank. Notwithstanding the foregoing,  nothing contained in this
Agreement  shall be construed as obligating  the Bank to agree or consent to any
such renewal and extension.

                  2.11 Maximum Lawful  Interest Rate. It is not the intention of
the Bank or the  Borrower  to violate  the laws of any  applicable  jurisdiction
relating to usury or other restrictions on the maximum lawful interest rate. The
Loan  Documents  and all other  agreements  between the  Borrower  and the Bank,
whether  written  or oral,  are  hereby  limited  so that in no event  shall the
interest  paid or  agreed  to be paid to the Bank for the  use,  forbearance  or
detention of money loaned,  or for the payment or performance of any covenant or
obligation  contained  herein or in any other Loan Document,  exceed the maximum
amount  permissible under applicable law. If from any  circumstances  whatsoever
fulfillment of any provision  hereof or of any other Loan Document,  at the time
the performance of such provision shall be due, shall involve  transcending  the
limit of validity  prescribed by law,  then,  ipso facto,  the  obligation to be
fulfilled  shall be  reduced  to the  limit of such  validity.  If from any such
circumstances,  the Bank shall ever receive  anything of value  deemed  interest
under  applicable  law which would exceed  interest at the highest  lawful rate,
such  excessive  interest  shall be applied to the  reduction  of the  principal
amount owing  hereunder,  and not the payment of interest,  or if such excessive
interest exceeds any unpaid balance of principal,  such excess shall be refunded
to the  Borrower.  All sums  paid or  agreed to be paid to the Bank for the use,
forbearance or detention of monies shall, to the extent  permitted by applicable
law, be amortized,  prorated,  allocated and spread  throughout the full term of
such indebtedness  until payment in full so that the rate of interest on account
of such indebtedness is uniform throughout the term thereof. This paragraph 2.11
shall  control  every  other  provision  of the  Loan  Documents  and all  other
agreements between the Bank and the Borrower contemplated thereby.

                  2.12 Closing. The Closing shall be held on or before April 23,
1999,  at 10:00,  a.m.,  at the  offices of the Bank,  1601 S.E.  19th,  Edmond,
Oklahoma,  or at such other time,  date or place as may be agreeable to the Bank
and the Borrower.

         3. GUARANTY AND COLLATERAL

                  3.1 Prior  Collateral  Unaffected.  Nothing in this  Agreement
shall be deemed to affect or impair the validity,  enforceability or priority of
the security  agreement and other  collateral  pledges  previously  executed and
delivered to Bank by Borrower,  and the Borrower  hereby  ratifies and reaffirms
said prior security agreement and other collateral pledges.

3.2 Guaranty.  To secure the timely payment of the  Indebtedness,  including the
Loan, the Borrower  shall cause the Bank to receive,  and there to be maintained
at all times during the term of this  Agreement  and until the  Indebtedness  is
paid and satisfied in full, the absolute and  continuing  guaranty of payment of
the Indebtedness  from the Guarantor.  At the Closing,  the Borrower shall cause
the Bank to receive the duly executed and delivered Guaranty from the Guarantor.

                  3.4  Collateral  Assignment.  At  Closing,  to  secure  timely
payment of the  Indebtedness,  Borrower  shall  execute  and deliver to Bank the

unenforceable, or materially impair its ability to fulfill its obligations under
the Loan  Documents.  The Borrower is duly  authorized,  qualified  and licensed

         days from  request,  Borrower  will  furnish  the Bank with such  other
         information concerning the business, operations and financial condition
         of the Borrower as may be reasonably  requested by the Bank,  from time
         to time.

                            6.1.6 Litigation. The Borrower will promptly furnish
         the Bank with written notice if at any time there are pending  lawsuits
         or other legal  proceedings  against  either the  Borrower or Guarantor
         where the aggregate  amount sued for or the total value of the property
         involved is in excess of  $10,000.00,  or is not  otherwise  adequately
         covered  by  insurance.  Thereafter,  the  Borrower  will keep the Bank
         informed on a current basis as to status of all such  litigation  until
         all matters are settled or adjudicated.

assessments,   governmental  charges  or  levies,  and  all  claims  for  labor,
materials, supplies, rent and other obligations which, if unpaid, might become a
lien against its property, excluding only liabilities being diligently contested
in good faith by  appropriate  legal  proceedings  and  against  which there are

accepted accounting principles.

                  6.4  Maintenance.  The Borrower will  maintain its  existence,
remain licensed or qualified and in good standing in each  jurisdiction in which
it holds any  properties  or conducts any  business,  except where failure to be
qualified or licensed would not have a material  adverse effect on the financial
condition,  business operations or properties of the Borrower, taken as a whole,
or render  any of  Borrower's  material  agreements  void or  unenforceable,  or
materially  impair the Borrower's  ability to fulfill its obligations  under the
Loan Documents. The Borrower will maintain all franchises,  permits, trademarks,
trade names,  and licenses  necessary or useful in the operation of its business
as heretofore operated and as to be operated as contemplated hereby,  subject to
changes  in the  ordinary  course  of  business,  and  maintain  or  cause to be

material  respects with all statutes,  laws, rules or regulations to which it is

generally accepted accounting principles.  Borrower will promptly notify Bank in
the event  Borrower  receives  any notice  from any  governmental  agency of any
alleged failure to comply with any such laws, rules or regulations.

special  counsel  and all filing  fees,  recording  costs,  examinations  of and

                  Upon the occurrence of an Event of Default, the Borrower will,
from  time to time  within  ten (10)  days  after a  request  made by the  Bank,
reimburse the Bank for all amounts reasonably expended,  advanced or incurred by
the Bank to satisfy any obligation of the Borrower under the Loan Documents,  or
to collect upon the Note or any other obligations  included in the Indebtedness,
or to enforce  the rights of the Bank under the Loan  Documents,  which  amounts

Borrower  with  insurance  companies  satisfactory  to the Bank,  in amounts and
against  risks  satisfactory  to the Bank, to the extent  insurance  coverage is
required by applicable  state and federal  regulatory  agencies or is consistent
with  insurance  coverage   customarily  or  typically   maintained  by  similar
businesses which are similarly  situated,  and the Bank will be furnished with a
certificate  of insurance in form and substance  satisfactory  to the Bank.  The
Borrower will not commit or suffer to be committed any act whereby any insurance
required  hereby shall or may be suspended,  impaired or defeated,  nor will the
Borrower  suffer or permit its  properties  to be used in a manner not permitted
under any applicable policy of insurance then in effect.

                  6.10  Financial Covenants.

         Loan, shall be at least $14,000,000.00.

                            As used  herein,  "Tangible  Net  Worth"  shall mean
         Borrower's assets (excluding loans and advances to employees,  goodwill
         and intangible assets) less total liabilities  (excluding  subordinated
         Debt),  as  reflected  on  Borrower's  most  recent  monthly  financial
         statement,  or in the case of the  Borrower's  Tangible Net Worth as of
         November 30, 1999, as reflected on Borrower's  audited annual financial
         statement.

necessary  or  appropriate  to  properly  perfect  Borrower's  rights  to assert

Borrower does business.  Borrower will further timely take such action as may be
necessary or appropriate to foreclose such liens or otherwise collect Borrower's
Accounts Receivables.

     6.13 Lock Box  Arrangement.  All payments on Borrower's  Receivables and on
the Aggreko Note will be directed for deposit to a post office box designated by
Bank,  and over which Bank will  exercise  exclusive  control.  Borrower  hereby
agrees that Bank may, as Borrower's attorney in fact (which appointment shall be
deemed coupled with an interest and shall be irrevocable during the term of this
Agreement),  take possession of all remittances to such post office box, endorse
Borrower's name thereon,  and deposit such remittance in Borrower's  account for
application to the Indebtedness. Borrower further agrees that Bank may take such
other actions,  for and on behalf of Borrower and in Borrower's  name, place and
stead, as may, in Bank's good faith judgment,  be necessary or helpful to effect
collection of Borrower's  accounts and  application  of such  collections to the
Indebtedness.
                  6.14  Non-Usage  Fee. On June 30,  1999,  September  30, 1999,

plus amounts reserved under special arrangements between Bank and Borrower.

         7.  NEGATIVE  COVENANTS.  So long as any  Indebtedness  is unpaid,  the
Borrower will not perform or permit to be performed  any of the  following  acts
unless the Bank shall otherwise agree in writing:

                  7.1  Creation or Existence  of Liens.  The  Borrower  will not
create,  assume  or  suffer  to exist  any  mortgage,  pledge,  lien,  charge or

deposits to secure payment of worker's compensation,  unemployment insurance and
similar  benefits;  (ii) statutory  liens,  against which there are  established
reserves in accordance with generally accepted accounting principles,  and which
(a) are being contested in good faith by appropriate legal  proceedings,  or (b)
arise in the  ordinary  course of the  Borrower's  business  and secure  current
obligations  of the Borrower  which are not in default;  (iv) liens for property
taxes not yet due; (v) liens for Debt as reflected on Exhibit "F."

                  7.2      Intentionally Omitted.

                  7.3      Intentionally Omitted.

                  7 4 Limitation on Dividends and Redemption.  Provided no Event
of Default has occurred  and is  continuing,  Borrower may pay  dividends to its
shareholders.  Upon the  occurrence  of an Event of Default,  Borrower  will not
directly or  indirectly  (i) declare or pay, or become  obligated  to declare or

dividends, or make any other distribution, by reduction or capital or otherwise,
in  respect  of any class of stock of the  Borrower,  (ii)  purchase,  redeem or

not directly or indirectly,  guarantee, co-sign, agree to purchase or repurchase
or provide  funds in  respect  of, or  otherwise  become or remain  liable  with
respect to, indebtedness of any character of any other person or entity,  except

covered by insurance.

discontinue  or make any  material  change  in the  nature  of its  business  as

                  7.8 Changes to Method of  Accounting.  The  Borrower  will not
make any  material  change  in its  method of  accounting  for  purposes  of the

any payment of principal on its subordinated  debentures,  and will pay interest
only as and when due under the  express  terms of the  subordinated  debentures.
Upon  the  occurrence  of a  Default,  Borrower  will  make no  payments  on its
subordinated debenture without Bank's prior consent.

         8. EVENTS OF DEFAULT.  The  occurrence of any of the following  events,

principal of the Loan as and when the same shall have become due and payable, or
any  failure of the  Borrower to pay any  interest on the Loan,  or any fees due

warranty ceases to be complied with in any material respect, and the Borrower or
the applicable Guarantor fails to correct such false or erroneous representation
or to comply with such  warranty  within twenty (20) Business Days after written

incapable of being corrected); or,

(iv)  commence  any  proceeding  relating  to  the  bankruptcy,  reorganization,

their respective properties having a fair market value in an aggregate amount in

         9.   REMEDIES.

                  9.1  Acceleration of  Indebtedness  Upon the occurrence of any
Event of Default  specified in paragraph  8.1,  the Bank's  obligations  to make
Advances  on the Loan shall  automatically  be  terminated  and the Note and all
other Indebtedness shall become immediately due and payable,  all without notice
or  demand.  Upon the  occurrence  of any other  Event of Default  specified  in
paragraph 8, the Bank,  without  further  notice or demand,  may, at its option,
terminate  the  Loan  and  its  obligation  to make  Advances  and  declare  all
Indebtedness  to be  immediately  due and payable,  whereupon  the same shall be
forthwith due and payable.  The Bank shall  promptly  advise the Borrower of any
such  declaration,  but  failure  to do so shall not  impair  the effect of such
declaration.  Upon such acceleration of maturity,  the Bank shall be entitled to
exercise  all  remedies  available  to it under the Loan  Documents or otherwise
under applicable law, including without  limitation:  (i) terminating the Bank's
obligations and the Borrower's rights under this Agreement,  and (ii) commencing
one or more  actions  against the  Borrower  and/or the  Guarantor to reduce the
claim of the Bank against the Borrower and/or the Guarantor to judgment.  In the
event the Bank  elects to enforce  its rights  under any one or more of the Loan
Documents selectively and successively, such action shall not be deemed a waiver
or discharge of any other right until such time as the Bank shall have been paid
in full all Indebtedness.
                                       19


<PAGE>


                  9.2  Waiver of  Default.  The Bank may,  by an  instrument  in
writing,  waive any Default or Event of Default and any of the  consequences  of
such Default or Event of Default, and, in such event, the Bank, the Borrower and
the Guarantor shall be restored to their respective former positions, rights and
obligations  hereunder.  Any Default or Event of Default so waived shall for all
purposes of this  Agreement be deemed to have been cured and not be  continuing,
but no such waiver shall extend to any  subsequent  or other Default or Event of
Default or impair any  consequence of such  subsequent or other Default or Event
of Default.

                  9.3  Deposits  Setoff.  Regardless  of  the  adequacy  of  any
collateral  held by the Bank, any deposits or other sums credited by or due from
the Bank to the Borrower shall at all times constitute  collateral  security for
the Indebtedness and, upon the occurrence of an Event of Default, may be set off
against  the  absolute or  contingent,  due or to become  due,  now  existing or
hereafter arising,  Indebtedness of the Borrower to the Bank. The rights granted
by this  paragraph  9.3 shall be in addition to the rights of the Bank under any
statutory banker's lien or the common law right of set off. This paragraph shall
not apply to any  monies of which the  Borrower  is only the  beneficial  owner,
regardless of the name in which the money is deposited, nor shall this paragraph
apply to any monies  which the Borrower is  contractually  obligated to spend in
whole or in part for the accounts of others,  provided  that the Borrower  shall
have  established  special  accounts  or given  the  Bank  written  notice  that
particular  funds  are  beneficially  owned  by  others  or  are  dedicated  for
particular  expenditures.  If the  Borrower  fails  to  establish  such  special
accounts  and fails to give  such  notice,  the Bank may  assume  that  funds on
deposit to the account of the Borrower  belong solely to the named depositor and
are subject to this paragraph 9.3.

          10. TERM.  This Agreement  shall remain in full force and effect until
all Indebtedness of Borrower to Bank has been paid in full.

          11.      GENERAL PROVISIONS.

                  11.1  Participating  Lenders.  The Borrower  understands that,
although  the Note  names the Bank as the  holder  thereof,  the Bank may sell a
participation  interest  in the  Loan  to one or  more  other  lenders,  and the
Borrower agrees that,  subject to the terms of the agreements of  participation,
each  participating  lender  will  be  entitled  to rely  on the  terms  of this
Agreement and the other Loan Documents as fully as if such participating  lender
had been named as the holder of such Note and named in the other Loan Documents.

                  11.2 Hold Harmless.  Except for a successful claim against the
Bank by the  Borrower,  the Borrower will  indemnify and hold the Bank,  and any
participant  in any or one or more of the Loans,  harmless  from all  liability,
loss, damages or expense, including reasonable attorney's fees, that the Bank or
any such  participant  may incur in good faith as a result of entering  into the
Loan Documents, making any Advances, or in compliance with or in the enforcement
of the terms of the Loan Documents.

                  11.3 Cumulative  Remedies.  No failure on the part of the Bank
to  exercise,  and no delay in  exercising,  any right or remedy  under the Loan
Documents  shall  operate as a waiver  thereof,  nor shall any single or partial
exercise by the Bank of any right thereunder preclude any other or further right
of exercise  thereof or the  exercise of any other right.  The  remedies  herein
provided are cumulative and not alternative.

                              REVOLVING CREDIT NOTE



$6,500,000.00                             April 23, 1999 Oklahoma City, Oklahoma


                  FOR VALUE  RECEIVED,  the  undersigned,  Tower Tech,  Inc., an
Oklahoma  corporation (the  "Borrower"),  hereby promises to pay to the order of
People First Bank (the  "Bank"),  the lesser of the principal sum of Six Million
Five Hundred Thousand Dollars  ($6,500,000.00) or the aggregate unpaid principal
amount of all revolving  credit loans made by the Bank to the Borrower  pursuant
to the Loan  Agreement (as  hereinafter  defined),  payable in full on April 30,
2000,  provided,  however,  that should the principal amounts outstanding on all
Advances  made  hereunder  exceed the lesser of the  Commitment or the Borrowing
Base (as those terms are defined in the Loan  Agreement)  at any time during the
term hereof,  the Borrower  will promptly  pay,  without  demand by the Bank, an
amount sufficient to reduce the then-outstanding  principal balance on this Note
to an amount which does not exceed the lesser of the Commitment or the Borrowing
Base.

                  Interest  shall  be  paid on any  and  all  principal  amounts
outstanding  hereunder from time to time from the date any Advance is made until
this Revolving Credit Note is paid in full, on the last day of each month during
the term hereof,  commencing May 31, 1999,  with all accrued unpaid interest due
and payable on June 1, 2000.

                  Interest  shall  accrue at the rate of  interest  equal to the
"Base Rate" (as hereinafter  defined) plus 2.0% per annum. As used herein, "Base
Rate" shall mean that fluctuating annual rate of interest published from time to
time in the Money Rates Section of the Wall Street  Journal as the "Prime Rate."
Each  change in the per annum  interest  rate  charged  hereunder  shall  become
effective,  without notice (which notice is hereby waived),  on the date of each
change in the Base Rate (or any component  thereof).  As of April 23, 1999,  the
Base Rate is 7.75% per annum and the interest  rate provided for herein is 9.75%
per annum. The Bank may, from time to time,  extend credit to anyone at rates of
interest varying from, and having no relationship to, the Base Rate.

                  All  computations  of interest  hereunder shall be made on the
basis of a year of 360 days for the actual number of days elapsed, including the
first day but excluding the last.

                  Both principal and interest are payable in lawful money of the
United  States of  America to the Bank at its  offices  at 1601 SE 19th  Street,
Edmond,  Oklahoma 73013. All Advances made by the Bank to the Borrower  pursuant
to the Loan Agreement and all payments made on account of principal hereof shall
be recorded by the Bank on its books. The unpaid principal  balance set forth on
the books of the Bank shall be  presumptive  evidence  of the  principal  amount
owing and unpaid on this Revolving Credit Note.

disposition shall be for a price not less than the fair market value of any such
assets and shall be pursuant to  commercially  reasonable  terms and conditions,
and provided further that such sales, transfers and dispositions will not create
an Event of Default  under any other  provision  of this  Agreement  or the Loan
Agreement.

executive office and its chief place of business and its records  concerning its
accounts and contract rights in said location.

     3.7 Location of  Collateral  and Notice of Removal.  The  Collateral is now
located in the State of Oklahoma, and, except for sales of Inventory in Debtor's
ordinary  course of  business,  Debtor shall keep the  Collateral  in said state

notice of its intention to remove the Collateral  (or any portion  thereof) from

                  3.8  Collections.  Upon the occurrence of an Event of Default,

right, either in Secured Party's own name or in the name of Debtor, to take such

Upon the request of Secured Party,  after the occurrence of an Event of Default,
Debtor will give notice to account  debtors of the assignment of or the granting
of a security  interest in any property  included in the  Collateral,  requiring
such account debtors to pay all sums due directly to Secured Party.  Debtor will
make  entries on its books and  records in form  satisfactory  to Secured  Party
disclosing  the  absolute  and  unconditional  assignment  to  Secured  Party of
property  included in the  Collateral.  In accordance  with normal  practices of
Secured Party,  invoices to and other requests for payment from account  debtors
in connection  with the Collateral  will, upon Secured Party's request after the
occurrence  of an Event of Default,  clearly  direct  payments to be mailed to a
post office box  controlled by Secured Party in  accordance  with  directions of
Secured Party,  so as to afford Secured Party rights and control over Collateral
pursuant to a "lock box"  arrangement.  Debtor does hereby appoint Secured Party
as its true and lawful attorney, with power of substitution (such appointment to
be effective  immediately,  without  notice,  upon the occurrence of an Event of
Default),  to take control in any manner of  Collateral,  to endorse the name of
Debtor thereon, to sign Debtor's name on any proof of claim in any bankruptcy or
similar proceedings against account debtors, to sign Debtor's name on any notice
of lien or similar proceeding, and to do all other acts and things necessary, in
Secured  Party's sole  discretion,  to effect and protect Secured Party's rights
and powers described in this paragraph 3.8 or otherwise in this Agreement.

         4.  Default.  The term  "Event of  Default"  for all  purposes  of this
Agreement shall have the meaning set forth in the Loan Agreement.

         5.  Remedies.  Upon the  occurrence  of any Event of Default and at any
time thereafter,  Secured Party shall have and may exercise the following rights
and remedies, without notice to Debtor:

                  5.1  Acceleration.  Declare the Indebtedness to be immediately
due and payable, whereupon the same shall become forthwith due and payable.

                  5.2  All  Legal   Remedies.   Proceed   to   selectively   and
successively  enforce and exercise any and all rights and remedies which Secured
Party  may  have  under  this  Agreement,  any  other  applicable  agreement  or
applicable law including without limitation:  (i) commencing one or more actions
against  Debtor  and  reducing  the claims of Secured  Party  against  Debtor to
judgment,  (ii)  foreclosure or other  enforcement of Secured  Party's  security
interest in the  Collateral,  or any portion  thereof,  or other  enforcement of
Secured  Party's  rights and  remedies  in  respect  of and to recover  upon the
Collateral,  through  judicial  action or  otherwise,  including  all  available
remedies under the applicable provisions of the Code, (iii) payment or discharge
of any claim or lien,  prior or  subordinate,  in  respect of or  affecting  the
Collateral.

                  5.3 Cash  Equivalent  Items.  As  regards  any  portion of the
Collateral  consisting of cash equivalent items (e.g.,  checks,  drafts or other
items convertible at face), Secured Party may immediately apply them against the
Indebtedness  and for  this  purpose  Debtor  agrees  that  such  items  will be
considered identical in character to cash proceeds.

     5.4 Assembly of  Collateral.  Require Debtor to assemble the Collateral and
make it  available to Secured  Party at a location  within the State of Oklahoma
designated by Secured Party which is reasonably convenient to all parties.

                  5.5  Possession of Collateral.  Take  possession of and remove
the  Collateral  wherever  the same may be  located,  without  demand or notice,
without  any court  order or other  process  of law and  without  incurring  any
liability to Debtor for any damages occasioned by such taking of possession.

                  5.6  Disposition.  Sell,  lease or  otherwise  dispose  of the
Collateral  at  private  or  public  sale,  in bulk or in  parcels,  and,  where
permitted by law,  without having the  Collateral  present at the place of sale.
Unless  the  Collateral  is  perishable  or its  appears  that the  value of the
Collateral will decline speedily or the Collateral is a type customarily sold on
a  recognized  market,  or unless  Debtor  has  signed a  statement  (after  the
occurrence  of an Event of Default)  renouncing or modifying  Debtor's  right to
notice,  Secured Party will give Debtor  reasonable notice of the time and place
of any public  sale or other  disposition  thereof  or the time after  which any
private sale or other  disposition  thereof is to be made. The  requirements  of
reasonable  notice  shall be met if such  notice is given to Debtor at least ten
(10) days before the time of any such sale or disposition.

                  5.7 Costs and Expenses. Recover from Debtor an amount equal to
all costs,  expenses and attorney  fees  incurred by Secured Party in connection
with the  exercise  of rights and  remedies  contained  or  referred  to herein,
together with interest on such sums at the default rates applicable to the Notes
from time to time.

                  5.8  Selective  Enforcement.  In the event Secured Party shall
elect to selectively and successively enforce its rights and remedies in respect
of any of the  Collateral,  pursuant to any applicable  agreements or otherwise,
such  action  shall  not be  deemed a waiver or  discharge  of any other  right,
remedy,  lien or encumbrance until such time as the Indebtedness shall have been
paid in full.

                  5.9 Waiver of Default.  Secured Party may, by an instrument in
writing  signed by Secured  Party,  waive any Event of Default  which shall have
occurred and any of the consequences  thereof, and, in such event, Secured Party
and Debtor shall be restored to their respective  former  positions,  rights and
obligations.  Any Event of  Default  so waived  shall for all  purposes  of this
Agreement  be deemed to have been  cured and not to be  continuing,  but no such
waiver  shall extend to any  subsequent  or other Event of Default or impair any
consequence thereof.

                  5.10 Deposits: Setoff. Regardless of the adequacy of any other
collateral held by Secured Party (including  without limitation the Collateral),
any deposits or other sums credited by or due from Secured Party to Debtor shall
at all times constitute  collateral security for the Indebtedness and may be set
off against the Indebtedness. The rights granted by this paragraph 5.10 shall be
in addition to the rights of Secured Party under any statutory  banker's lien or
common law right of set off.

                  5.11 Collections.  Exercise any and all rights and remedies of
Debtor relating to the Collateral including,  but not by way of limitation,  the
right to collect,  demand, receive,  settle,  compromise,  adjust or sue for all
amounts due thereon or  thereunder  and the right either in Secured  Party's own
name or in the name of Debtor to take such legal or other  proceedings as Debtor
might  have taken  except for this  Agreement,  together  with all other  rights
specified in paragraph 3.8 hereof.

                  5.12  Application of Payments.  During the  continuance of any
Event of  Default,  all  payments  received  by Secured  Party in respect of the
Indebtedness, whether from Debtor, any guarantor, recoveries upon any portion of
the Collateral or otherwise, may be applied by Secured Party to any liabilities,
obligations or  indebtedness  included in the  Indebtedness  selected by Secured
Party in its sole and exclusive discretion.

                  5.13 Cumulative  Remedies.  All rights and remedies of Secured
Party hereunder are cumulative and may be exercised  singularly or concurrently,
and the exercise of any one or more of them shall not be a waiver of any other.

                  5.14 Secured  Party's  Satisfaction  of Debtor's  Obligations.
Upon the  occurrence  of any event  which,  but for the  giving of notice or the
passage of time,  would  constitute an Event of Default,  Secured Party may, but
shall not be obligated to, pay,  satisfy or cure any liability or obligations of
Debtor  arising  out of or relating to this  Agreement  or the Note,  and Debtor
will,  from time to time  within ten (10) days  after a request  made by Secured
Party, reimburse Secured Party for all amounts expended, advanced or incurred by
Secured Party in connection with such payment,  cure or  satisfaction,  together
with interest on such sums at the rate applicable to the Note from time to time.

         6.   Miscellaneous.

                  6.1 Power of Attorney.  To effectuate the terms and provisions
hereof, Debtor hereby designates and appoints Secured Party and its designees or
agents as attorney-in-fact of Debtor, irrevocably and with power of substitution

adjust and compromise any claims under insurance policies;  to execute releases;
and to do all  other  acts  and  things  necessary  and  advisable  in the  sole
discretion of Secured  Party to carry out and enforce this  Security  Agreement.

                  THIS  AGREEMENT  is made and  entered  into  this  23rd day of
April, 1999, by Tower Tech, Inc., an Oklahoma corporation ("Borrower"), in favor
of People First Bank, an Oklahoma state banking association ("Bank").

W I T N E S S E T H:

                  WHEREAS,  Borrower  has  executed  and  delivered  to  Bank  a
Promissory Note (the "Note"), of even date herewith,  in the principal amount of
$6,500,000.00; and,

                  WHEREAS,  Borrower  is  the  owner  and  holder  of a  certain
Promissory Note (the "Aggreko Note") in the principal  amount of  $1,350,000.00,
dated December 4, 1998, executed by Aggreko, Inc. ("Aggreko"); and,

                  WHEREAS, as a condition to the extension of credit to Borrower
evidenced by the Note,  Bank has required that Borrower  assign the Aggreko Note
to Bank as  additional  security  for  repayment  of the Note and that  Borrower
deliver to Bank  Aggreko's  written  acknowledgment  of, and  consent  to,  this
Collateral Assignment, all as more particularly set forth hereinafter.

                  NOW, THEREFORE,  for valuable  consideration,  the receipt and
sufficiency of which is hereby acknowledged, the parties agree as follows:

         1. Grant of Security Interest.  Borrower hereby grants Bank a first and
prior  security  interest in the Aggreko  Note,  including all rights to payment
thereunder,  proceeds  and  products  thereof  and  substitutions  therefor.  In
connection  therewith,  Borrower  has,  concurrently  with the execution of this
Agreement,  transferred and delivered the Aggreko Note to Bank, duly endorsed in
Bank's favor.

         2. Representations.  Warranties and  Covenants.   Borrower represents,
warrants and covenants that:

                  2.1   Ownership of Collateral.  Borrower is the owner of  the
Aggreko Note,  free and clear of any lien,  pledge or encumbrance.

                  2.2   No Restrictions.  There  are  no  restrictions upon  the
transfer of the Aggreko  Note to Bank,  except as provided in Section 5 therein.
Borrower  has  obtained  the  written  approval  of Aggreko  to this  Collateral
Assignment of the Aggreko Note.

                  2.3 Limitation on  Enforcement.  Amendment or Renewal.  During
the term of this  Agreement,  Borrower  will not,  without  Bank's prior written
consent:

                           (a)  Commence  or take  any  action  to  enforce  the
                           Aggreko  Note;  or, (b) Grant or make any  extension,
                           renewal or modification to the Aggreko Note.
                                                                1
         3. Return of  Collateral.  Upon  payment in full of the Note,  the Bank
shall transfer the Aggreko Note to Borrower, without recourse.

         4. Default. The terms "Default" and  "Event of Default" for purposes of
this Agreement shall have the same meanings as set forth in that certain Amended
and Restated  Loan  Agreement  (the "Loan  Agreement"),  of even date  herewith,
between Borrower, Bank and others.

         5.  Remedies.  Upon the  occurrence  of any Event of Default and at any
time  thereafter,  Bank shall have and may  exercise  the  following  rights and
remedies, without notice to Borrower:

                  5.1  Acceleration.  Declare the indebtedness  evidenced by the
Note  to be  immediately  due and  payable,  whereupon  the  same  shall  become
forthwith due and payable.

                  5.2  All  Legal   Remedies.   Proceed   to   selectively   and
successfully enforce and exercise any and all rights and remedies which Bank may
have under this Collateral  Assignment  and/or the Loan Agreement and other Loan
Documents,  any other applicable agreement or applicable law including,  without
limitation: (i) commencing one or more actions against Borrower and reducing the
claims  of  Bank  against  Borrower  to  judgment;  (ii)  foreclosure  or  other
enforcement  of Bank's  security  interest in the Aggreko  Note,  or any portion
thereof,  or other  enforcement of Bank's rights and remedies in respect of, and
to recover  upon,  the  Aggreko  Note,  through  judicial  action or  otherwise,
including all available remedies under the applicable  provisions of the Uniform
Commercial  Code; and, (iii) payment or discharge of any claim or lien, prior or
subordinate, in respect to, or affecting the Aggreko Note.

                  5.3 Disposition. Upon ten (10) days' notice to Borrower, given
as hereinafter provided, and without liability for any diminution in price which
may have  occurred,  sell all or any portion of the Aggreko  Note in such manner
and for such price as the Bank may  determine.  At any bona fide public sale the
Bank shall be free to purchase all or any part of the Aggreko  Note.  Out of the
proceeds of any sale the Bank may retain an amount  equal to the  principal  and
interest then due on the Note,  plus the amount of the expenses of the sale, and
Bank's reasonable costs of collection,  including attorneys fees, and shall then
pay any balance of such proceeds to Borrower.  In the event that the proceeds of
any sale are  insufficient  to cover the principal and interest of the Note plus
expenses  of the sale,  and Bank's  reasonable  costs of  collection,  including
attorneys fees, Borrower shall be liable to the Bank for any deficiency.

                  5.4 Costs and Expenses.  Recover from Borrower an amount equal
to all costs,  expenses  and  reasonable  attorneys'  fees  incurred  by Bank in
connection  with the  exercise of rights and  remedies  contained or referred to
herein, together with interest on such sums at the rate of interest set forth in
the Note.

     5.5 Selective Enforcement. In the event Bank shall elect to selectively and
successively  enforce its rights and  remedies  in respect to the Aggreko  Note,
pursuant to any  applicable  agreements or  otherwise,  such action shall not be
deemed a waiver or  discharge of any other right,  remedy,  lien or  encumbrance
until such time as the Note shall have been paid in full. To the fullest  extent
permitted  by law,  Borrower  waives all rights to require  that the  collateral
described in this Agreement be marshalled prior to sale.

and any of the consequences thereof, and, in such event, Bank and Borrower shall
be restored to their respective  former positions,  rights and obligations.  Any
Default or Event of Default so waived shall for all purposes of this  Collateral
Assignment  be deemed to have been cured and not to be  continuing,  but no such
waiver shall extend to any  subsequent  or other  Default or Event of Default or
impair any consequences thereof.

                               GUARANTY AGREEMENT


                  FOR  VALUABLE  CONSIDERATION,  the  receipt  of  which  by the
undersigned  (the  "Guarantor'1)  is hereby  acknowledged,  and to induce People
First Bank (the  "Lender")  to extend  credit to Tower Tech,  Inc.,  an Oklahoma
corporation  (the  "Borrower"),  in the aggregate  amount of  $6,500,000.00,  as
evidenced by that certain  Promissory  Note (the "Note") of even date  herewith,
the Guarantor hereby covenants and agrees with the Lender as follows:

         1. The  Guarantor  unconditionally  and  absolutely  guarantees  to the
Lender,  its  successors  and  assigns,  the full and prompt  payment  when due,
whether at stated  maturity,  by  acceleration  or  otherwise,  and at all times
thereafter,  of the Note, all other  extensions of credit by the Lender in favor
of the Borrower,  all other  obligations of the Borrower to the Lender,  and any
extensions,  renewals or modifications  thereof,  howsoever created,  arising or
evidenced,  whether  direct  or  indirect,  absolute  or  contingent,  or now or
hereafter  existing or due or to become due, and all interest  thereon,  and the
Guarantor further guarantees the full, punctual and faithful performance of each
and every  covenant,  term,  condition  and  obligation  to be  performed by the
Borrower in respect to the Note,  any mortgage and security  agreement  securing
the payment of the Note and  Borrower's  performance of the Amended and Restated
Loan Agreement of even date herewith,  by and between the Lender,  the Borrower,
the  Guarantor and others (as amended from time to time,  the "Loan  Agreement")
and any  document  executed  in  connection  therewith  (all such  indebtedness,
extensions of credit and obligations being hereinafter  collectively  called the
"Liabilities").

         The undersigned  further agrees to pay all expenses  (including but not
limited to attorneys'  fees, court costs and legal expenses) paid or incurred by
the  Lender,   its  successors  or  assigns,   in  endeavoring  to  collect  the
Liabilities,  or any part thereof, and in enforcing this Guaranty. The Guarantor
further  guarantees  that all payments made by the Borrower to the Lender on any
obligation  hereby  guaranteed will, when made, be final and agrees that, if any
such payment is recovered  from, or repaid by, the Lender in whole or in part in
any bankruptcy,  insolvency or similar  proceeding  instituted by or against the
Borrower, this Guaranty shall continue to be fully applicable to such obligation
to the same extent as though the payment so  recovered  or repaid had never been
originally made on such obligation.

     2. This  Guaranty  shall,  in all respects,  be a continuing,  absolute and
unconditional guaranty of payment, and not collection,  and shall remain in full
force and effect (notwithstanding,  without limitation, the validity, regularity
or  enforceability  of the Note, the Loan Agreement or any document  executed in
connection  therewith,  or any  other  agreement  or  document  relating  to the
Liabilities).  The Guarantor further agrees that its obligation  hereunder shall
be unconditional  irrespective of any other  circumstances which might otherwise
constitute a discharge at law or in equity of a guarantor or surety.

         3.  Without  in any  way  affecting  the  liability  of  the  Guarantor
hereunder, the Lender may, from time to time, at its sole discretion and without
notice to the Guarantor, take any or all of the following actions:

                                    (a)     Retain or obtain a security interest
                  in  any  property  to  secure  any  of the Liabilities or any
                  obligation hereunder;

                  secondary  obligation of any obligor or obligors,  in addition
                  to the Borrower and the Guarantor,  with respect to any of the
                  Liabilities;

                                    (c) Extend or renew for one or more  periods
                  (whether or not longer  than the  original  period),  alter or
                  exchange any of the Liabilities,  or release or compromise any
                  obligation of the Borrower or the Guarantor or any  obligation
                  of any nature of any other  obligor with respect to any of the
                  Liabilities; or,

                                    (d) Fail to perfect or release its  security
                  interest in, or surrender,  release or permit any substitution
                  or exchange for, all or any part of any property  securing any
                  of the Liabilities or any obligation  hereunder,  or extend or
                  renew for one or more periods  (whether or not longer than the
                  original period) or release, compromise, alter or exchange any
                  obligations  of any nature of any obligor  with respect to any
                  such property; or,

                                    (e)  Resort  to  the  Guarantor  or  to  any
                  collateral  securing this Guaranty for payment or  performance
                  of any of the  Liabilities,  whether or not the  Lender  shall
                  have resorted to any property  securing any of the Liabilities
                  or any obligation  hereunder or shall have  proceeded  against
                  the Borrower or any other  obligor  primarily  or  secondarily
                  obligated with respect to any of the Liabilities.

         4. Nothing herein  contained shall prevent the Lender from suing on any
instrument or document  evidencing all or any part of the  Liabilities,  or from
foreclosing  any  lien  held  by the  Lender  upon  any  property  securing  the
Liabilities  or from  exercising  any other  rights  available to it against the
Borrower,  and, if such  foreclosure  or other remedy is availed of only the net
proceeds  therefrom,  after  deduction of all charges and expenses of every kind
and nature whatsoever, shall be applied in reduction of the Liabilities, and the
Lender shall not be required to institute  proceedings to recover any deficiency
as a condition of payment  hereunder or enforcement  hereof.  At any sale of any
security or  collateral  for the  Liabilities  or any part  thereof,  whether by
foreclosure or otherwise, the Lender may, at its discretion, purchase all or any
part of such  collateral so sold or offered for sale for its own account and may
apply against the amount bid therefor the balance due on the Liabilities.

         5. Any amounts received by the Lender from whatsoever source on account
of the  Liabilities  may be  applied  by it toward  the  payment  of such of the
Liabilities,  and in such order of  application,  as the Lender may from time to
time elect; and,  notwithstanding any payments made by or for the account of the
Guarantor  pursuant to this Guaranty,  the Guarantor  shall not be subrogated to
any rights of the Lender until such time as the Lender has  received  payment of
the full  amount of all  Liabilities  and of all  obligations  of the  Guarantor
hereunder.

         6. The Guarantor hereby expressly waives:

                                  (a)     Notice of the acceptance by the Lender
                  of this Guaranty;

                                  (b)     Notice of the existence or creation or
                  nonpayment of all or any of the Liabilities;

                                  (c)    Presentment, demand, notice of dishonor
                  or protest;
                                        2

<PAGE>

                                  (d)     All setoffs and counterclaims; and,

                                  (e)     All   diligence   in   collection   or
                  protection  of or  realization  upon  the  Liabilities  or any
                  portion thereof, any obligation hereunder, or any security for
                  or guaranty of any of the foregoing.

         7. The Lender may, from time to time,  without notice to the Guarantor,
assign or transfer any of the Liabilities  owing to it or any interest  therein;
and,   notwithstanding  any  such  assignment  or  transfer  or  any  subsequent
assignment or transfer thereof, such Liabilities shall be and remain Liabilities
for the purposes of this Guaranty,  and each and every  immediate and successive
assignee or  transferee  of any of the  Liabilities  or of any interest  therein
shall,  to the extent of the  interest  of such  assignee or  transferee  in the
Liabilities,  be entitled to the benefits of this Guaranty to the same extent as
if such assignee or transferee were the Lender;  provided,  however, that unless
the  Lender  shall  otherwise  consent  in  writing,  the  Lender  shall have an
unimpaired right, prior and superior to that of any such assignee or transferee,
to  enforce  this  Guaranty,  for the  benefit  of the Lender as to those of the
Liabilities owing to it which the Lender has not assigned or transferred.

         8. No delay on the part of the Lender in the  exercise  of any right or
remedy shall operate as a waiver thereof,  and no single or partial  exercise by
the  Lender of any right or remedy  shall  preclude  other or  further  exercise
thereof or the exercise of any other right or remedy; nor shall any modification
or waiver of any of the  provisions of this Guaranty be binding upon the Lender,
except as expressly  set forth in a writing duly signed and  delivered on behalf
of the  Lender.  No action of the Lender  permitted  hereunder  shall in any way
affect or impair the rights of the Lender and the  obligation  of the  Guarantor
under this Guaranty.

         9.  The  Guarantor  agrees  and  acknowledges  that the  execution  and
delivery of this Guaranty by the Guarantor is for a valid,  proper and bona fide
business purpose of the Guarantor.

         10.  The  Guarantor   agrees  to  maintain   adequate  records  of  all
transactions  so that at any time and  from  time to time the true and  complete
financial condition of the Guarantor may be readily determined.

         Guarantor shall furnish to the Lender, within 60 days following the end
of each calendar year while any portion of the Liabilities  remains unpaid,  the
Guarantor's full and complete financial  statement,  prepared in form acceptable
to Lender and on a basis consistent with the prior year. Guarantor shall further
furnish  Lender  with a full,  true and  correct  copy of  Guarantor's  personal
Federal income tax return within two weeks of filing, but in no event later than
October 31 of each year.

         11. This  Guaranty  shall be binding  upon the  Guarantor  and upon the
heirs, personal  representatives,  successors and assigns of the Guarantor;  and
all  references  herein to the Borrower shall be deemed to include any successor
or successors, whether immediate or remote, of the Borrower.

         12. This  instrument  is  executed  and  delivered  as an incident to a
transaction  negotiated and consummated in, and shall be construed  according to
the laws of, the State of Oklahoma.

         13. The Guarantor  hereby agrees that the rights of the Lender  created
by this Guaranty shall be cumulative and not in the alternative.

                                        3

         14.  Wherever  possible,  each  provision  of this  Guaranty  shall  be
interpreted  in such manner as to be effective and valid under  applicable  law,
but if any  provision of this  Guaranty  shall be  prohibited by or held invalid
under  such law,  such  provision  shall be  ineffective  to the  extent of such
prohibition or invalidity,  without invalidating the remainder of such provision
or the remaining provisions of this Guaranty.

                  SIGNED AND DELIVERED this 23rd day of April, 1999.

THE STATE OF OKLAHOMA

COUNTY OF CLEVELAND                              KNOW ALL MEN BY THESE PRESENTS:


         THIS  AGREEMENT  (herein so called) is made and entered  into as of the
14th day of June, 1999, by and between Lender, and Borrower,



                                  WITNESSETH:


WHEREAS,  TOWER TECH,  INC., an Oklahoma  Corporation  executed and delivered to
SOUTHWESTERN  BANK & TRUST COMPANY that promissory note dated April 14, 1998, in
the original principal sum of $2,000,000.00 (the "Note") which is currently held
by Lender and;

WHEREAS,  the Note is secured by a mortgage  lien  conveyed in a mortgage  dated
April 14, 1998 recorded in Book 2941,  Page 19 of the Official Public Records of
Cleveland  County,  Oklahoma  (the  "Mortgage")  covering the real property (the
"Property") owned by Borrower, more fully described as follows:

A part of the Southeast Quarter (SE/4) of Section Eleven (11), Township Ten (10)
North,  Range Four (4) West of the Indian Meridian,  Cleveland County,  Oklahoma
and being more particularly  described in Exhibit "A" attached hereto and made a
part hereof for all purposes.

WHEREAS,  the Note is further secured by certain other security (the "Additional
Security")  more  fully  described  as  follows,  to-wit:   Commercial  Guaranty
Agreement  executed by Harold  Curtis  dated June 17,  1999;  the  Mortgage  and
Additional Security being collectively  referred to as the "Security Documents";
and

WHEREAS, the Note presently matures on June 14, 1999, and Borrower has requested
and Lender has agreed to amend and modify the Note and Security Documents.

NOW THEREFORE,  in  consideration  of the sum of Ten and No/1O0 Dollars ($10.00)
and the  exchange of other good and valuable  consideration  paid by each of the
parties  to  the  other,   the  receipt  and  sufficiency  of  which  is  hereby
acknowledged, Lender and Borrower AGREE AS FOLLOWS:

1.  Acknowledgment  of Outstanding  Balance.  The outstanding  principal balance
of the Note as of the date hereof is $2,010,000.00.

2.  Renewal  and  Extension  of  Maturity.  The Note is hereby  renewed  and the
maturity  of the Note is hereby  extended to June 14,  2002  ("Revised  Maturity
Date").

3.  Amendment of Interest  Rate. The interest rate in the Note is hereby amended
as follows:
Interest  shall  accrue  on the  unpaid  balance  of this Note from time to time
outstanding  which is not past due,  calculated  on a 300 day annual  basis (the
"Rate"), except as otherwise provided herein, as follows:

The lesser of (a) the Loan Rate (hereinafter  defined) in effect from day to day
or (b) the Highest Lawful Rate (hereinafter  defined) in effect from day to day.
The term "Loan Rate"  shall mean the sum of  one-half of one percent  (0.5%) and
the Index as hereafter  defined.  The Loan Rate shall be subject to change daily
with changes in the Index.

As of the date of this Note,  the lesser of the Loan Rate and the Highest Lawful
Rate is eight and one quarter  percent  (8.25%) per annum.  Any change in either
the Loan Rate or the Highest  Lawful Rate shall,  after  Lender  gives only such
notice as may be required by  applicable  law or  regulation,  be effective  for
purposes  of  determining  the Rate as of the opening of business on the date of
any such change.

The Index is:

The Wall Street  Journal  Prime Rate which is the highest rate shown as the base
rate on corporate  loans posted by at least 75% of the nation's 30 largest banks
as published daily in the Money Rates Section of the Wall Street Journal.

The Index currently is seven and three quarters percent (7.75%) per annum.

The  "Highest  Lawful Rate" is the maximum  lawful rate which may be  contracted
for,  charged,  taken,  received,  or reserved by Lender in accordance  with the
applicable  laws of the State of Oklahoma (or  applicable  United States federal
law to the extent that it permits Lender to contract for, charge,  take, receive
or reserve a greater amount of interest than under  Oklahoma  law),  taking into
account  all  charges  made in  connection  with this loan which are  treated as
interest under applicable law.

If at any time (i) the Loan Rate,  (ii) interest on matured unpaid  amounts,  if
applicable,  as  provided  for  herein  or in any of the other  Loan  Documents,
together  with (iii) all fees and  charges,  if any,  contracted  for,  charged,
received,  taken or reserved  by Lender in  connection  with the loan  evidenced
hereby which are treated as interest  under  applicable law  (collectively,  the
'Charges'),  computed over the full term of this Note, exceed the Highest Lawful
Rate, the rate of interest payable hereunder,  together with all Charges,  shall
be limited to the Highest Lawful Rate;  provided,  however,  that any subsequent
reduction  in the Loan Rate shall not cause a reduction  of the rate of interest
payable  hereunder  below the  Highest  Lawful  Rate  until the total  amount of
interest earned hereunder, together with all Charges, equals the total amount of
interest  which would have accrued on the Loan Rate if such interest rate had at
all times been in effect.  Changes in the Loan Rate  resulting  from a change in
the Index shall be subject to the provisions of this paragraph.

4.  Required  Payments.  Principal  and accrued and unpaid  interest on the Note
shall be due and payable as follows:

Principal  and  interest  shall be due and  payable in monthly  installments  of
$17,126.52  or more,  each,  payable on the 14th day of each and every  calendar
month,  beginning July 14, 1999, and continuing  regularly  thereafter until the
whole of said sum, with  interest,  has been duly paid, (or until June 14, 2002,
when the entire amount of principal and interest then remaining unpaid, shall be
then due and payable)  interest being  calculated on the unpaid principal to the
date of each  installment  paid  and the  payment  made  credited  first  to the
discharge  of the  interest  accrued  and the  balance to the  reduction  of the
principal.

Interest,  computed on the unpaid  principal  balance,  shall be due and payable
monthly on the same dates as, and in addition to the installments of principal.

In the event any monthly  installment is not received by Note Holder within days
from due date,  Borrower  shall pay a late  charge of five  percent  (5%) of the
regularly scheduled payment of principal and interest.

5.  Financial  Statements  and  Appraisals.  Borrower and each person liable for
repayment  of the Note  shall  furnish  to Lender on an  annual  basis,  balance
sheets,  income  statements and cash flow  statements in such form and detail as
Lender  shall  require.  Borrower  shall  furnish to Lender upon  request,  such
appraisals of the Property as may be required of Lender under  applicable  State
or Federal laws and regulations issued pursuant thereto.

6. Hazardous Substances.  Borrower shall not cause or permit the presence,  use,
disposal, storage, or release of any Hazardous Substances on or in the Property.
Borrower  shall not do, nor allow  anyone  else to do,  anything  affecting  the
Property  that is in  violation of any  Environmental  Law.  The  preceding  two
sentences  shall not apply to the  presence,  use, or storage on the Property of
small  quantities of Hazardous  Substances  that are generally  recognized to be
appropriate  to normal  use and  maintenance  of the  Property.  Borrower  shall
promptly give Lender written notice of any investigation, claim, demand, lawsuit
or other  action by any  governmental  or  regulatory  agency or  private  party
involving the Property and any Hazardous Substance or Environmental Law of which
Borrower  has actual  knowledge.  If  Borrower  learns,  or is  notified  by any
governmental or regulatory  authority,  that any removal or other remediation of
any Hazardous  Substance  affecting the Property is  necessary,  Borrower  shall
promptly take all necessary  remedial  actions in accordance with  Environmental
Law. As used in this Paragraph 6, 'Hazardous  Substances'  are those  substances
defined as toxic or hazardous  substances by Environmental Law and the following
substances:  gasoline,  kerosene,  other flammable or toxic petroleum  products,
toxic  pesticides  and  herbicides,   volatile  solvents,  materials  containing
asbestos or formaldehyde,  and radioactive materials.  As used in this Paragraph
6, 'Environmental Law' means federal laws and laws of the jurisdiction where the
Property is located that relate to health, safety or environmental protection.

7.  Additional  Provisions.  THIS LOAN IS PAYABLE IN FULL AT MATURITY.  BORROWER
MUST REPAY THE ENTIIRE  PRINCIPAL  BALANCE OF THE LOAN AND UNPAID  INTEREST THEN
DUE.  THE  LENDER IS UNDER NO  OBLIGATION  TO  REFINANCE  THE LOAN AT THAT TIME.
BORROWER WILL,  THEREFORE,  BE REQUIRED TO MAKE PAYMENT OUT OF OTHER ASSETS THAT
BORROWER MAY OWN, OR BORROWER WILL HAVE TO FIND A LENDER WHICH MAY BE THE LENDER
BORROWER HAS THIS LOAN WITH,  WILLING TO LEND  BORROWER  THE MONEY.  IF BORROWER
REFINANCES  THIS LOAN AT MATURITY,  BORROWER WILL HAVE TO PAY SOME OR ALL OF THE
CLOSING  COSTS  NORMALLY  ASSOCIATED  WITH A NEW LOAN EVEN IF  BORROWER  OBTAINS
REFINANCING  FROM THE SAME LENDER.  THIS LENDER WILL CONSIDER AN  APPLICATION TO
REFINANCE  THE BALLOON  PAYMENT AT THE TIME PAYMENT IS DUE, ON THE SAME BASIS AS
ALL OTHER NEW MORTGAGE LOAN APPLICATIONS.



8.  Ratification of Security  Documents.  Borrower and Lender further agree that
the liens,  assignments and security interests created by the Security Documents
shall continue and carry forward until the Note and all  indebtedness  evidenced
thereby is paid in full.  Borrower  further  agrees that Lender is the holder of
the  Note and the  Security  Documents  and that  such  liens,  assignments  and
security  interests  are hereby  ratified and  affirmed as valid and  subsisting
against the Property, and that this Agreement shall in no manner vitiate, affect
or impair the Note or the Security  Documents  (except as expressly  modified in
this Agreement), and that such liens, assignments,  and security interests shall
not in any manner be waived,  released,  altered or modified  until the Note and
all other obligations  secured by the Security Documents  (including any and all
subsequent renewals and extensions) have been paid in full.

9.  Release  of Claims.  Borrower  hereby  RELEASES,  RELINQUISHES  and  forever
DISCHARGES   Lender,   its   agents,   officers,   directors.    employees   and
representatives of and from any and all claims,  demands,  actions and causes of
action of any and every kind or character,  whether known or unknown, present or
future, which Borrower may have against Lender, its agents, officers, directors,
employees  and  representatives  arising  out of or with  respect to any and all
transactions  relating to the Note and the Security Documents occurring prior to
the date hereof.

10.      Miscellaneous.

(a)  Except  as  modified  hereby,  all  terms  and  provisions  of the Note and
     Security  Documents  remain  unchanged,  are  expressly  ratified and shall
     continue in full force and effect,  and Borrower  acknowledges  and affirms
     Borrower's liability to Lender thereunder. In the event of an inconsistency
     between this Agreement and the terms of the Note and/or Security Documents,
     this Agreement shall govern.
(b)  Borrower hereby agrees to pay all costs and expenses  incurred by Lender in
     connection with the execution and  administration  of this  Agreement,  the
     reinstatement and modification of the Note and/or Security  Documents,  and
     any other documents executed in connection herewith.

contained shall constitute a default under the Note and Security Documents,  and
shall allow  Lender to exercise any or all of its remedies set forth in the Note
and  Security  Documents  or at law or in equity.  (d) Lender  does not,  by its
execution of this Agreement, waive any rights it may have against any person not
a party hereto.  (e) This  Agreement  may be executed in multiple  counterparts,
each of which shall  constitute an original  instrument,  but all of which shall
constitute one and the same  Agreement.  (f) Borrower agrees that this Agreement
and all of the covenants and agreements  contained  herein shall be binding upon
the parties hereto and shall inure to the benefit of and be binding upon each of
their  respective  heirs,  executors,  legal  representatives,   successors  and
permitted assigns.

11.      No  Oral  Agreements.  THIS  WRITTEN  AGREEMENT  REPRESENTS  THE  FINAL
         AGREEMENTS  BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE
         OF  PRIOR,  CONTEMPORANEOUS,  OR  SUBSEQUENT  ORAL  AGREEMENTS  OF  THE
         PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Indebtedness, payment of any lien affecting the Property, or the restoration and
repair of the Property.  If Lender  elects to apply the proceeds to  restoration
and repair,  Borrower shall repair or replace the damaged or destroyed  Property

installment  of  principal  and interest on the note a sum equal to the premiums

the Property,  or any part thereof,  plus taxes and assessments  next due on the

Accelerate Indebtedness.  Lender may declare the unpaid principal balance of the

at its option, may: (a) foreclose this Mortgage and sell the Property by a power
of sale (which power of sale is hereby  granted by Borrower to Lender)  pursuant
to the Oklahoma Power of Sale Mortgage  Foreclosure Act or any successor statute
(the "Power of Sale Act");  (b) foreclose this Mortgage by judicial  proceeding;
and/or (c) invoke any other remedies  provided herein or in any other instrument

injunctive  relief  (prohibitive  or mandatory)  with respect to the  Borrower's
covenants  and  agreements  contained in this  Mortgage and the other  documents
evidencing and securing the loan secured hereby, whether or not Lender elects to
accelerate the sums secured hereby.

UCC Remedies.  With respect to all or any part of the Personal Property,  Lender
shall have all the rights and  remedies of a secured  party  under the  Oklahoma
Uniform Commercial Code.

Lender's Power.  Borrower  hereby jointly and severally  authorizes and empowers
Lender  to  sell  all or any  portion  of the  Property  together  or in lots or
parcels,  as Lender  may deem  expedient,  and to  execute  and  deliver  to the
purchaser or purchasers of such Property good and sufficient deeds of conveyance
of fee simple title,  or of lesser estates,  and bills of sale and  assignments,
with covenants of general warranty made on behalf of Borrower. In no event shall
Lender be required  to  exhibit,  present or display at any such sale any of the
Property to be sold at such sale.  The Lender making such sale shall receive the
proceeds of the sale and shall apply the same as provided below.  Payment of the
purchase  price to Lender shall  satisfy the  liability of the  purchaser at any
such sale of the Property,  and such person shall not be bound to look after the
application of the proceeds.

Appoint  Receiver.  Lender shall have the right to have a receiver  appointed to
take  possession of all or any part of the  Property,  with the power to protect
and preserve the  Property,  to operate the Property  preceding  foreclosure  or
sale,  and to collect the Rents from the Property and apply the  proceeds,  over
and above the cost of the receivership,  against the Indebtedness.  The receiver
may serve without bond if permitted by law. Lender's right to the appointment of
a receiver shall exist whether or not the apparent value of the Property exceeds
the  Indebtedness  by a  substantial  amount.  Employment  by  Lender  shall not
disqualify a person from serving as a receiver.

Tenancy at Sufferance.  If Borrower  remains in possession of the Property after
the Property is sold as provided above or Lender  otherwise  becomes entitled to
possession  of the Property  upon default of Borrower,  Borrower  shall become a
tenant at sufferance  of Lender or the  purchaser of the Property and shall,  at
Lenders option, either: (a) pay a reasonable rental for the use of the Property:
(b) vacate the Property  immediately  upon the demand of Lender;  or (c) if such
tenants  refuse  to  surrender  possession  of the  Property  upon  demand,  the
purchaser  shall be entitled to institute and maintain the  statutory  action of
forcible  entry and detainer and procure a writ of  possession  thereunder,  and
Borrower expressly waives all damages sustained by reason thereof.

Appraisement  and Sale of the  Property.  To the extent  permitted by applicable
law, Borrower hereby waives any and all rights to have the Property  marshalled.
In exercising  its rights and remedies,  the Lender shall be free to sell all or
any part of the  Property  together  or  separately,  in one sale or by separate
sales.  Lender shall be entitled to bid at any public sale on all or any portion
of the  Property.  Lender  may  convey  all or any part of the  Property  to the
highest bidder for cash with a general  warranty  binding  Borrower,  subject to
prior liens and to other exceptions to the conveyance and warranty. Appraisement
of the Property is hereby waived or not waived at Lenders option, which shall be
exercised at the time  judgment is entered in any  foreclosure  hereof or at any
time prior thereto. The affidavit of any person having knowledge of the facts to
the effect  that proper  notice as  required by Oklahoma  law was given shall be
prima facie  evidence  of the fact that such notice was in fact given.  Recitals
and  statements  of fact in any notice or in any  conveyance to the purchaser or
purchasers of the Property in any foreclosure  sale under this Mortgage shall be
prima  facie  evidence  of the truth of such facts,  and all  prerequisites  and
requirements  necessary  to the  validity  of any such sale shall be presumed to
have been performed. Any sale under the powers granted by this Mortgage shall be
a perpetual bar against Borrower, Borrowers heirs, successors, assigns and legal
representatives.

Proceeds.  Lender shall pay the proceeds of any sale of the Property: (a) first,
to the expenses of foreclosure, including reasonable fees or charges paid to the
Lender,  including but not limited to fees for  enforcing the lien,  posting for
sale, selling, or releasing the Property:  (b) then to Lender the full amount of
the  Indebtedness;  (c) then to any  amount  required  by law to be paid  before
payment to Borrower; and (d) the balance.
if any, to Borrower.

Waiver;  Election of Remedies.  A waiver by any party of a breach of a provision
of this  Mortgage  shall not  constitute a waiver of or  prejudice  that party's
rights  otherwise to demand strict  compliance  with that provision or any other
provision.  Election by Lender to pursue any remedy  provided in this  Mortgage,
the Indebtedness,  in any Related Document, or provided by law shall not exclude
pursuit of any other  remedy,  and an election to make  expenditures  or to take
action to perform an obligation of Borrower under this Mortgage after failure of
Borrower to perform  shall not affect  Lenders right to declare a default and to
exercise any of its remedies.

Attorneys' Fees;  Expenses.  If Lender  institutes any suit or action to enforce
any of the terms of this Mortgage,  Lender shall be entitled to recover such sum
as the court  may  adjudge  reasonable  as  attorneys'  fees at trial and on any
appeal,  whether or not any court action is involved,  all  reasonable  expenses
incurred by Lender  which in Lenders  opinion are  necessary at any time for the
protection of its interest or the  enforcement of its rights shall become a part
of the  indebtedness,  be payable on demand and shall bear  interest at the Note
rate  from  the date of  expenditure  until  repaid.  Expenses  covered  by this
paragraph  include,  without  limitation,  however  subject to any limits  under
applicable  law,  Lenders  reasonable  attorneys' fees whether or not there is a
lawsuit, including attorneys' fees for bankruptcy proceedings (including efforts
to  modify  or  vacate  any  automatic  stay  or  injunction),  appeals  and any
anticipated  post-judgment  collection services,  the cost of searching records,
obtaining title reports (including  foreclosure  reports),  surveyors'  reports,
environmental  assessments,  appraisal fees, title  insurance.  and fees for the
Lender,  to the extent  permitted by applicable law.  Borrower will also pay any
court  costs,  in  addition  to all other sums  provided by law. In the event of
foreclosure of this Mortgage,  Lender shall be entitled to recover from Borrower
Lenders reasonable attorneys' fees and actual disbursements necessarily incurred
by Lender in pursuing such foreclosure.

filing a map or plat of the Real  Property.  including the dedication of streets
or other rights to the public: (b) join in granting any easement or creating any
restriction on the Real  Property:  and (c) join in any  subordination  or other
agreement affecting this Mortgage or the interest of Lender under this Mortgage.

Obligations  to  Notify.  Lender  shall not be  obligated  to  notify  any other
lienholder of the Property of the commencement of a foreclosure proceeding or of
the  commencement  of any other  action to which  Lender  may avail  itself as a
remedy, except to the extent required by applicable law or by written agreement.

Foreclosure.  In  addition  to the rights and  remedies  set forth  above,  with
respect to all or any part of the  Property,  the Lender shall have the right to
foreclose  by notice and sale,  and by judicial  foreclosure,  in either case in
accordance with and to the full extent provided by applicable law.

NOTICES TO BORROWER AND OTHER  PARTIES.  Any notice under this Mortgage shall be
in writing and shall be effective when actually  delivered or, if mailed,  shall
be deemed  effective  when  deposited  in the United  States  mail first  class,
certified  mail,  postage  prepaid.  directed  to the  addresses  shown near the
beginning of this  Mortgage.  Any party may change its address for notices under
this Mortgage by giving formal written  notice to the other parties,  specifying
that the  purpose  of the notice is to change the  party's  address.  For notice
purposes,  Borrower  agrees to keep Lender  informed  at all times of  Borrowers
current address.

MISCELLANEOUS  PROVISIONS.  The following miscellaneous provisions are a part of
this Mortgage:

Amendments. This Mortgage, together with any Related Documents,  constitutes the
entire understanding and agreement of the parties as to the matters set forth in
this Mortgage. No alteration of or amendment to this Mortgage shall be effective
unless given in writing and signed by the party or parties  sought to be charged
or bound by the alteration or amendment.

Applicable  Law.  This  Mortgage  has been  delivered  to Lender and accepted by
Lender  in the  State  of  Oklahoma.  This  Mortgage  shall be  governed  by and
construed in  accordance  with the laws of the State of Oklahoma and  applicable
Federal laws.

Caption Headings. Caption headings in this Mortgage are for convenience purposes
only  and are not to be used to  interpret  or  define  the  provisions  of this
Mortgage.

Limitation of interest. All agreements between Borrower and Lender are expressly
limited  so that in no  contingency  or event  whatsoever  whether  by reason of
advancement of the proceeds of the Indebtedness, acceleration of maturity of the
Indebtedness hereof, or otherwise, shall the amount paid or agreed to be paid to
the Lender for the use,  forbearance,  or  detention of the money to be advanced
hereunder  exceed the highest  rate  permissible  under the laws of the State of
Oklahoma and of the United States,  (to the extent not preempted by Federal law,
if any)  and any  subsequent  revisions  repeals,  or  judicial  interpretations
thereof,  to the extent any of same are applicable hereto and thereto.  If, from
any  circumstance  whatsoever,  fulfillment of any  provisions  hereof or of the
Indebtedness or any other agreement  referred to herein or therein shall, at the
time  fulfillment of such provision be due,  involve  transcending  the limit of
validity  prescribed  by law that a court  of  competent  jurisdiction  may deem
applicable  hereto,  then ipso facto the  obligations  to be fulfilled  shall be
reduced to the limit of such validity,  and if from any  circumstance the Lender
shall ever receive as interest an amount which would be excessive  interest,  it
shall:  (a) be applied to the reduction of the unpaid  principal  balance of the
Indebtedness:  or (b) be  refunded  to  Borrower  and  not to the  payment  of
interest.  It is further agreed.  without limitation of the foregoing,  that all
calculations of the rate of interest contracted for, charged, or received on the
indebtedness  evidenced  or  secured  hereby  that are made for the  purpose  of
determining whether such rate exceeds the maximum lawful contract rate, shall be
made,  to the extent  permitted by  applicable  law, by  amortizing,  prorating,
allocating,  and spreading  throughout the full stated term of the Indebtedness
so that such rate of interest on account of such Indebtedness, as so calculated,
is uniform throughout the term thereof. This provision shall control every other
provision of all agreements between Borrower and the Lender.

Merger.  There  shall be no merger of the  interest  or estate  created  by this
Mortgage  with any other  interest or estate in the Property at any time held by
or for the benefit of Lender in any  capacity,  without  the written  consent of
Lender.

Multiple Panties. All obligations of Borrower under this Mortgage shall be joint
and several,  and all references to Borrower shall mean each and every Borrower.
This  means  that  each of the  persons  signing  below is  responsible  for all
obligations  in  this  Mortgage.  Where  any  one or  more  of the  parties  are
corporations or partnerships, it is not necessary for Lender to inquire into the
powers of any of the parties or of the officers, directors,  partners, or agents
acting or purporting to act on their behalf.

Severability.  If a court of competent  jurisdiction finds any provision of this
Mortgage to be invalid or unenforceable  as to any person or circumstance,  such
finding shall not render that provision invalid or unenforceable as to any other
persons or circumstances.  If feasible,  any such offending  provisions shall be
deemed to be modified  to be within the limits of  enforceability  or  validity;
however, if the offending provision cannot be so modified,  it shall be stricken
and all other  provisions  of this Mortgage in all other  respects  shall remain
valid and enforceable.

Successors and Assigns.  Subject to the  limitations  stated in this Mortgage on
transfer of Borrowers interest, this Mortgage shall be binding upon and inure to
the benefit of the parties,  their  successors and assigns.  If ownership of the
Property becomes vested in a person other than Borrower,  Lender, without notice
to Borrower,  may deal with Borrowers successors with reference to this Mortgage
and the  Indebtedness  by way of  forbearance  or  extension  without  releasing
Borrower  from  the   obligations  of  this  Mortgage  or  liability  under  the
Indebtedness.

Time  is of the  Essence.  Time is of the  essence  in the  performance  of this
Mortgage.

Waivers and Consents. Lender shall not be deemed to have waived any rights under
this Mortgage (or under the Related  Documents) unless such waiver is in writing
and signed by Lender.  No delay or omission on the part of Lender in  exercising
any right shall  operate as a waiver of such right or any other right.  A waiver
by any party of a provision of this Mortgage shall not constitute a waiver of or
prejudice the party's  right  otherwise to demand  strict  compliance  with that
provision or any other provision.  No prior waiver by Lender,  nor any course of
dealing between Lender and Borrower, shall constitute a waiver of any of Lenders
rights or any of Borrowers  obligations as to any future transactions,  whenever
consent by Lender is required in this Mortgage,  the granting of such consent by
Lender in any instance  shall not  constitute  continuing  consent to subsequent
instances where such consent is required.

FOR VALUE RECEIVED,  Borrower,  jointly and severally if more than one, promises
to pay to the order of Lender (which term shall include all  subsequent  holders
of this Note) at its offices set forth above or at such other  address as Lender
may from  time to time  designate.  in  lawful  money of the  United  States  of
America, the principal sum of $253,000.00, or so much thereof as may be advanced
and  outstanding  from time to time, with interest at the rate provided below on
the principal balance from time to time remaining unpaid, in the amounts, at the
times and upon the terms  provided  in this Note.  This Note is  performable  in
Bryan County, Oklahoma.

INTEREST  RATE.  Interest  shall accrue on the unpaid  balance of this Note from
time to time outstanding  which is not past due,  calculated on a 360 day annual
basis (the "Rate"), except as otherwise provided herein, as follows:

The lesser of (a) the Loan Rate (hereinafter  defined) in effect from day to day
or (b) the Highest Lawful Rate (hereinafter  defined) in effect from day to day.
The term "Loan Rate"  shall mean the sum of  one-half of one percent  (0.5%) and
the Index as hereafter  defined.  The Loan Rate shall be subject to change daily
with changes in the index.

As of the date of this Note,  the lesser of the Loan Rate and the Highest Lawful
Rate is eight and one quarter  percent  (8.25%) per annum.  Any change in either
the Loan Rate or the Highest  Lawful Rate shall,  after  Lender  gives only such
notice as may be required by  applicable  law or  regulation,  be effective  for
purposes  of  determining  the Rate as of the opening of business on the date of
any such change.

The Index is:

The Wall Street  Journal  Prime Rate which is the highest rate shown as the base
rate on corporate  loans posted by at least 75% of the nation's 30 largest banks
as published daily in the Money Rates Section of the Wall Street Journal.

The index currently is seven and three quarters percent (7.75%) per annum.

The  "Highest  Lawful Rate" is the maximum  lawful rate which may be  contracted
for,  charged,  taken,  received,  or reserved by Lender in accordance  with the
applicable  laws of the State of Oklahoma (or  applicable  United States federal
law to the extent that it permits Lender to contract for, charge,  take, receive
or reserve a greater amount of interest than under  Oklahoma  law),  taking into
account  all  charges  made in  connection  with this loan which are  treated as
interest under applicable law.

If at any time (i) the Loan Rate,  (ii) interest on matured unpaid  amounts,  if
applicable,  as  provided  for  herein  or in any of the other  Loan  Documents,
together  with (iii) all fees and  charges,  if any,  contracted  for,  charged,
received,  taken or reserved  by Lender in  connection  with the loan  evidenced
hereby which are treated as interest  under  applicable law  (collectively,  the
"Charges"),  computed over the full term of this Note, exceed the Highest Lawful
Rate, the rate of interest payable hereunder,  together with all Charges,  shall
be limited to the Highest Lawful Rate;  provided,  however,  that any subsequent
reduction  in the Loan Rate shall not cause a reduction  of the rate of interest
payable  hereunder  below the  Highest  Lawful  Rate  until the total  amount of
interest earned hereunder, together with all Charges, equals the total amount of
interest  which would have accrued on the Loan Rate if such interest rate had at
all times been in effect.  Changes in the Loan Rate  resulting  from a change in
the index shall be subject to the provisions of this paragraph.


PREPAYMENT.  Borrower  may  prepay  this  Note in  whole  or in part at any time
without being required to pay any penalty or premium for such privilege.  in the
event a prepayment is made,  such payment shall be applied first against accrued
but unpaid interest,  then to the discharge of any expenses for which the holder
of this Note may be  entitled to receive  reimbursement  under the terms of this
Note or under  the terms of any  other  documents  related  thereto  and  lastly
against the principal hereof.  Any partial prepayment shall not postpone the due
date or change the amount of any subsequent installment due hereunder.

PAST  DUE  PAYMENTS.  Lender  may  charge  and  collect  a late fee of 5% of any
scheduled  installment  more than 10 days past due. The annual  interest rate on
matured unpaid amounts shall be the highest lawful rate.

DISHONORED  CHECK CHARGE.  Borrower may pay a processing  fee of $15.00 for each
check given by Borrower to Lender as a payment on this loan which is dishonored.

month,  beginning July 17, 1999, and continuing  regularly  thereafter until the
whole of said sum, with  interest,  has been duly paid,  (or until June 17,2002,
when the entire amount of principal and interest then remaining unpaid, shall be
then due and payable)  interest being  calculated on the unpaid principal to the
date of each  installment  paid  and the  payment  made  credited  first  to the
discharge  of the  interest  accrued  and the  balance to the  reduction  of the
principal.

WAIVER.  Except as  otherwise  expressly  stated  in any of the Loan  Documents,
Borrower  and any and all  co-borrowers,  endorsers,  guarantors,  and  sureties
severally waive notice, notice of intent to accelerate,  notice of acceleration,
demand, grace, presentment for payment, and protest and agree that this Note and
all liens securing its payment may be extended and  re-extended and the time for
payment extended and re-extended from time to time without notice to them or any
of them,  and they  severally  agree that their  liability on or with respect to
this Note shall not be affected by any release or change in any  security at any
time  existing  or by any  failure  to  perfect or  maintain  perfection  of any
security interest in such security.

EVENTS OF DEFAULT.  It is especially  agreed that time is of the essence of this
Note. The following events shall constitute Events of Default:

1. Default in the timely  payment  (timely  payment shall mean payment within 10
days after notice of nonpayment) of any installment of principal and interest or
in the  performance  of any  covenant  or  provision  of any  Loan  Document  as
hereafter defined.

2. Borrower, or any Guarantor,  shall: (a) execute an assignment for the benefit
of creditors or take any action in furtherance  thereof; or (b) admit in writing
his inability to pay his debts generally as they become due; or (c) as a debtor,
file a petition,  case, proceeding,  or other action pursuant to, or voluntarily
seek the  benefit or  benefits  of any  debtor  relief law or take any action in
furtherance  thereof; or (d) seek,  acquiesce in, or suffer the appointment of a
receiver,  trustee,  or custodian of Borrower,  any  Guarantor,  the Property as
herein  defined,  in whole  or in  part,  or any  significant  portion  of other
property  belonging to Borrower or any Guarantor that affects  performance under
this Note; or (e) voluntarily become a party to any proceeding seeking to effect
a  suspension  or having  the effect of  suspending  any of the rights of Lender
granted or referred to in the Loan  Documents or take any action in  furtherance
thereof.

3. The filing of a petition, case, proceeding, or other action against Borrower,
or  any  Guarantor,  as a  debtor  under  any  debtor  relief  law;  or  seeking
appointment of a receiver,  trustee, or custodian of Borrower, or any Guarantor,
or of any property  described in the Loan  Documents or any part thereof,  or of
any  significant  portion  of  other  property  belonging  to  Borrower  or  any
Guarantor,  that affects its ability to perform  under this Note,  or seeking to
effect a  suspension  or having  the effect of  suspending  any of the rights of
Lender  granted or referred to in the Loan  Documents,  and: (a) Borrower or any
Guarantor  admits,  acquiesces in, or fails to contest the material  allegations
thereof; or (b) the petition, case, proceeding, or other action results in entry
of an order for relief or order granting the relief sought  against  Borrower or
any Guarantor;  or (c) the petition,  case,  proceeding,  or other action is not
permanently  dismissed  on or before the earlier of trial  thereon or sixty (60)
days next following the date of its filing.

4. The discovery by Lender that any warranty,  covenant,  or representation made
to Lender by or on behalf of Borrower  or any  Guarantor  is false,  misleading,
erroneous, or breached in any material respect.

A default  shall not be an Event of Default if the  default is cured  within ten
(10) days following the delivery of or the mailing of written notice from Lender
to Borrower's  most current  address as reflected in Lender's  business  records
specifying  the  existence  of any such  default.  If such  default is not cured
within the ten (10) day period, the default shall be an Event of Default without
need of any  further  notice  or action by  Lender,  except as may be  otherwise
required by law.

ACCELERATION  AND WAIVER OF NOTICE.  Upon the occurrence of an Event of Default,
the entire unpaid principal balance plus all accrued and unpaid interest due and
owing on this  Note and any and all other  indebtedness  of  Borrower  to Lender
shall, at the option of Lender,  become and be due and payable forthwith without
demand, notice of default,  notice of intent to accelerate,  or the acceleration
of the maturity hereof, notice of nonpayment, presentment, protest, or notice of
dishonor,  all of which  are  hereby  expressly  waived to the full  extent  not
prohibited by law by Borrower and each other liable  party.  Failure to exercise
this  option  upon  the  occurrence  of any  such  Event of  Default  shall  not
constitute  a waiver of the right to  exercise  such  option in the event of any
subsequent Event of Default.

COLLECTION  COSTS AND JOINT  AND  SEVERAL  LIABILITY.  If the  unpaid  principal
balance  plus all accrued and unpaid  interest due and owing on this Note is not
paid at maturity,  whether by acceleration or otherwise, and this Note is placed
in the  hands  of an  attorney  for  collection,  or suit is  filed  hereon,  or
proceedings  are  had  in  probate,  bankruptcy,  receivership,  reorganization,
arrangement, or other legal proceedings for collection hereof, Borrower and each
other  liable  party  agree  to pay  Lender  its  reasonable  collection  costs,
including a  reasonable  amount for  attorneys'  fees.  Borrower  and each other
liable  party is and shall be directly  and  primarily,  jointly and  severally,
liable for the payment of all sums due  hereunder,  under the Loan Documents and
under any instrument  securing the payment  hereof,  and Borrower and each other
liable party hereby  expressly  waives  bringing of Suit and diligence in taking
any action to collect any sums owing hereon and in the handling of any security,
and Borrower and each other liable party hereby consents to and agrees to remain
liable  hereon  regardless  of  any  renewals,  extensions  for  any  period  or
rearrangements  hereof,  or any release or  substitution  of security  hereof in
whole or in part,  with or without  notice,  from time to time,  before or after
maturity.

                                                                   INITIALS

                                                                   Loan No.

LOAN CHARGES. It is expressly stipulated and agreed to be the intent of Borrower
and Lender at all times to comply with the applicable Oklahoma law governing the
maximum  rate or amount of  interest  payable  on this Note or the  indebtedness
evidenced  hereby and by the other Loan Documents (or  applicable  United States
federal law to the extent that it permits the Borrower to contract for,  charge,
take,  reserve or receive a greater amount of interest than under Oklahoma law).
If the applicable law is ever  judicially  interpreted so as to render  usurious
any amount  called for under  this Note or under any of the Loan  Documents,  or
contracted  for,  charged,  taken,  reserved  or received  with  respect to such
indebtedness,  or if  Borrower's  exercise  of the option  herein  contained  to
accelerate the maturity of this Note or if any prepayment by Borrower results in
Borrower having paid any interest in excess of that permitted by applicable law,
then it is  Borrower's  and  Lender's  express  intent  that all excess  amounts
theretofore  collected  by Lender be credited on the  principal  balance of this
Note (or,  if this Note has been or would  thereby be paid in full,  refunded to
Borrower),  and  the  provisions  of this  Note  and the  other  Loan  Documents
immediately be deemed reformed and the amounts thereafter  collectible hereunder
and  thereunder  reduced,  without the  necessity  of the  execution  of any new
document,  so as to comply  with the  applicable  law,  but so as to permit  the
recovery of the fullest amount  otherwise  called for hereunder and  thereunder.
Notwithstanding anything to the contrary contained herein or in any of the other
Loan Documents,  it is not the intention of Lender to accelerate the maturity of
any interest that has not accrued at the time of such acceleration or to collect
unearned interest at the time of such  acceleration.  All sums paid or agreed to
be paid by Lender for the use,  forbearance  or  detention  of the  indebtedness
evidenced  hereby and by the other Loan Documents shall, to the extent permitted
by applicable law, be amortized,  prorated,  allocated and spread throughout the
full term of such indebtedness  until payment in full so that the rate or amount
of interest on account of such  indebtedness  does not exceed the usury  ceiling
from time to time in effect and applicable to such indebtedness evidenced hereby
for so long as debt is  outstanding.  To the extent  United  States  federal law
permits Lender to contract for,  charge or receive a greater amount of interest,
Lender will rely on United  States  federal  law  instead of state law,  for the
purpose of determining the Highest Lawful Rate.

RIGHT OF SET OFF.  Borrower grants to Lender a contractual  possessary  security
interest in and hereby assigns,  conveys,  delivers,  pledges,  and transfers to
Lender, all Borrower's right,  title and interest in and to Borrower's  accounts
with Lender (whether checking, savings or some other account), including without
limitation all accounts held jointly with someone else and all accounts Borrower
may open in the future,  excluding  however all IRA,  Keogh and trust  accounts.
Borrower authorizes Lender, to the extent permitted by applicable law, to charge
or set off all sums owing on this Note against any and all such amounts.

ADDITIONAL SECURITY. This Note is secured by all security agreements, collateral
assignments,  assignments,  guaranties, mortgages, and lien instruments executed
by Borrower (or by any Guarantor) in favor of Lender or any other holder of this
Note,  including  those  executed   simultaneously   herewith,   those  executed
heretofore  and  those  hereafter   executed,   and  by  all  such   agreements,
assignments,  guaranties,  and security  instruments securing the payment of all
other indebtedness of Borrower to Lender.

REMEDIES  OF LENDER.  Lender  shall have all  rights,  remedies,  and  recourses
granted in this Note, the Loan Documents and all other instruments  securing the
payment  hereof  and the  payment of all  indebtedness  of  Borrower  to Lender,
howsoever  evidenced,  and those which are available at law or equity, and same:
(a)  shall  be  cumulative  and  concurrent;  (b)  may  be  pursued  separately,
successively,  or  concurrently  against  Borrower or any other  liable party or
against  any one or more of them at the sole  discretion  of Lender  and in such
order as Lender, in its sole discretion,  shall determined; (c) may be exercised
as often as occasion therefore shall arise, it being agreed by Borrower that the
exercise or failure to exercise  any of the same shall in no event be  construed
as a waiver or release thereof or of any other right,  remedy, or recourse;  and
(d) are  intended  to be, and shall be,  nonexclusive.  If any part of this Note
cannot be enforced,  this fact will not affect the rest of this Note.  This loan
shall be governed by and construed in  accordance  with the laws of the State of
Oklahoma and applicable United States federal law.

NOTICES TO BORROWER  AND OTHER  PARTIES.  Any notice under this Note shall be in
writing and shall be effective when actually  delivered or, if mailed,  shall be
deemed effective when deposited in the United States mail first class, certified
mail,  postage  prepaid,  directed to the addresses  shown near the beginning of
this Note.  Any party may  change its  address  for  notices  under this Note by
giving formal written notice to the other parties,  specifying  that the purpose
of the notice is to change the party's address.  For notice  purposes,  Borrower
agrees to keep Lender informed at all times of Borrower's current address.

LOAN  DOCUMENTS.  This Note and all other  instruments  executed  in  connection
herewith and/or securing repayment hereof (the "Loan Documents"),  including but
not limited to:

(a)      The Additional Security as described above.

(b) Commercial Mortgage, Security Agreement,  Financing Statement and Assignment
of Rents given by Borrower to Lender and any subsequent  holder of this Note, of
even date herewith.

PROPERTY.  The property described in the Loan Documents (the "Property") is:

A part of the Southeast Quarter (SE/4) of Section Eleven (11), Township Ten (10)
North,  Range Four (4) West of the Indian Meridian,  Cleveland County,  Oklahoma

part hereof for all purposes.

J-Tech or Eunson breach any of their representations,  warranties, and covenants

the  entirety  of  any  damages,  judgments,   claims,  demands  or  liabilities
(collectively,  "Adverse  Consequences")  that Tower Tech  shall  suffer  caused

obligation  to  indemnify  Tower Tech from and against any Adverse  Consequences
caused by the breach of any  representation  or warranty of J-Tech or Eunson (i)

breaches in excess of $20,000  (after which point J-Tech will be obligated  only
to  indemnify  Tower Tech from and  against  further  Adverse  Consequences)  or
thereafter (ii) to the extent the Adverse  Consequences  Tower Tech has suffered
by reason of all such  breaches  exceeds the  Termination  Payment  (after which
point J-Tech will have no  obligation  to indemnify  Tower Tech from and against
further  such Adverse  Consequences);  provided,  however,  that any breach of a
representation or warranty arising out of fraud,  intentional  misrepresentation
or with  actual  knowledge  that it  contained  an untrue  statement  of fact or
omitted a fact  necessary  to make the  statement  not  misleading  shall not be
subject to such $20,000 threshold or the ceiling set by the Termination Payment.

Consequences  J-Tech shall suffer caused  proximately  by the breach;  provided,
however,  that Tower Tech shall not have any obligation to indemnify J-Tech from
and against any Adverse  Consequences caused by the breach of any representation
or  warranty  of Tower  Tech,  unless  such breach was the result of fraud or an
intentional misrepresentation (i) until J-Tech has suffered Adverse Consequences
by reason of all such  breaches  in excess of $20,000  (after  which point Tower
