                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.    Interim Financial Statements

      The  balance  sheet as of May 31,  1998,  and the  related  statements  of
      operations  for the three month and six month  periods  ended May 31, 1998
      and 1997 and the  statement  of cash flows for the six month  period ended
      May 31, 1998 and 1997 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.    Recently Issued Accounting Pronouncement

      In  February  1997,  the  Financial   Accounting  Standards  Board  issued
      Statement of Financial  Accounting  Standards No. 128,  Earnings Per Share
      ("FAS  128").  FAS 128  requires  presentation  of "basic"  and  "diluted"
      earnings per share,  as defined,  on the face of the income  statement for
      all entities  with complex  capital  structures.  FAS 128 is effective for
      financial statements issued for periods ending after December 15, 1997 and
      requires  restatement of all prior period earnings per share amounts.  The
      Company has adopted FAS 128 and has  restated all prior  periods.  FAS 128
      requires a reconciliation  of the numerators and denominators of the basic
      and diluted EPS computations. Options to purchase 210,894 shares of common
      stock at a weighted  average  price of $6.67 were  outstanding  during the
      three month and six month periods ended May 31, 1998 but were not included
      in the computation of diluted EPS because the effect of these  outstanding
      options would be antidilutive.  A  reconciliation  for the three month and
      six month periods ended May 31, 1997 is as follows:

3.    Debt

       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.  During the current  quarter this line was  increased to  $6,500,00.  This
financing  replaced a $2,000,000  line of credit payable to an  individual.  The
outstanding balance at May 31, 1998 was $4,200,721.  Interest is payable monthly
at a variable  rate of two basis  points  over  national  prime  rate.  The loan
matures  June 30, 1999.  The  agreement is  collateralized  by certain  accounts
receivable,  inventory,  rental  fleet and  patents.  The Company has received a
commitment to increase this line of credit to $5,000,000. Also, negotiations are
in process to further increase this line of credit to help fund increases in the
Company's rental fleet and growth in accounts receivable and inventory.

     In April 1998, the Company finalized a $2,000,000 construction loan for the
Oklahoma  City office  facility  which is expected  to cost  approximately  $2.1
million.  The loan  matures in April 1999 and bears  interest  at 9.5%,  payable
monthly.

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

   Three Months Ended May 31, 1998 Compared to Three Months Ended May 31, 1997

         For the three months ended May 31, 1998, total tower revenues increased
to  $5,865,233  from  $5,069,588  for the  comparable  period in the prior year.
During the current  three month period,  43 percent of total tower  revenues was
derived from sales of 77 modular  fiberglass cooling towers, 41 percent of total
tower revenues was derived from  construction of the modular  concrete tower, 12
percent of total tower  revenues was derived  from rental of modular  fiberglass
cooling  towers and 4 percent of total tower  revenues  was  derived  from other
revenues.  In the  comparable  three month  period of 1997,  66 percent of total
tower revenues was derived from sales of 86 modular  fiberglass  cooling towers,
22 percent of total tower revenues was derived from  construction of the modular
concrete  tower,  6 percent of total tower  revenues  was derived from rental of
modular cooling  towers,  and 6 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
decrease in fiberglass  tower  revenues for 1998 is due not only to the decrease
in the  quantity of units sold but also to the sales of smaller  capacity,  less
expensive  units.  The decrease in the number of units sold is due  primarily 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.
It is estimated  that these delays will have a  significantly  smaller  negative
impact on the third quarter  1998.  The Company has tried to minimize the impact
by continuing to aggressively market and sell its TTMT series modular fiberglass
cooling  tower which is continuing  to be assembled in its  Chickasha,  Oklahoma
plant. In addition to the delays, the Company entered into a rental contract for
80 of the Company's largest modular fiberglass cooling towers.  Over 70 of these
towers had to be produced during April and May for rental start-up  beginning in
June 1998. Consequently,  several customer deliveries were rescheduled for third
quarter  1998.  The  rental  revenue  from this  large  rental  project  will be
recognized  mostly in the third quarter of 1998.  The increase in concrete tower
revenues is due to the increase in the number and size of jobs  completed and in
process.  The  increase in tower  rentals is due to an increase in the number of
rental  contracts  as well as an increase in contract  amounts.  The Company has
been  focusing on marketing  this segment of the business and has  significantly
increased the number of units available for rental. Management believes that the
Company  now has  the  largest  rental  cooling  tower  fleet  in the  industry.
Accordingly,  steady growth in rental tower revenues is anticipated. Other tower
revenue is down from the previous  year due to the same reasons that tower sales
decreased.  No licensing  agreements  were  finalized  in the second  quarter of
fiscal 1998 although  negotiations  are  continuing  for agreements in China and
Northern Europe.

         The Company's cost of goods sold and constructed during the three month
period ended May 31, 1998 was $5,712,658, or 97 percent of total tower revenues,
as  compared to  $3,918,558  or 77 percent of total  tower  revenues  during the
comparable  period in 1997.  The increase in cost of goods sold and  constructed
during the second quarter of 1998 resulted from increased  construction costs of
the modular concrete cooling towers.  Overall margin for the second quarter 1998
decreased  primarily as a result of concrete  cooling tower cost overruns mainly
on two projects. Total estimated losses on these projects were recognized in the
second quarter 1998. Lower margins were also incurred in the modular  fiberglass
cooling  line  due to the  additional  costs  associated  with  the  OKC  plant,
equipment and tooling delays. However, those decreases in margins were partially
offset by an increase in rental  revenues,  which is a higher margin  operation.
Included  in the cost of goods  sold for the second  quarter  1998 is $87,234 to
retrofit and service towers  previously  sold.  This compares to expenditures of
$106,399 during the comparable period in the prior year. In 1995, design changes
were made and a complete quality control system was implemented which management
believes will continue to control such per unit expenditures in future periods.

         The three  month  period  ended May 31,  1998  reflected  a 113 percent
increase  in  general  and  administrative  expenses  from  $295,031  in 1997 to
$629,600. The increase is due mainly to the addition of office staff and related
expenses,  additional  expenses related to the OKC facility,  and an increase of
$125,000 in the allowance for doubtful accounts. Selling expenses increased from
$291,029 to $462,885 due to increased  sales and marketing  efforts for both the
TTMT Series and the concrete  modular cooling  towers,  including an increase in
sales staff and expenses related primarily to the opening of direct domestic and
international sales offices. Management expects the increased investment to have
a positive  impact on  revenues  in future  periods.  Research  and  development
expenses  decreased  from $124,311 in the second  quarter of 1997 to $112,787 in
the second  quarter of 1998.  Although  the  Company has no fixed  research  and
development budget,  management does expect to continue to research  refinements
in cooling tower design and construction.

         The Company's  loss from  operations for the three months ended May 31,
1998 was $1,052,697 as compared to income of $440,659 for the comparable  period
in the prior year. After interest expense,  miscellaneous  items, and income tax
benefit,  the Company's net loss is $754,358  compared to net income of $275,456
for the quarter ended May 31, 1997.

         The Company  recognized an income tax benefit of $502,905 for the three
months ended May 31, 1998,  compared to no income tax benefit or expense for the
comparable  period in 1997. FAS 109 requires that the Company record a valuation
allowance  when it is more  likely  than not  that  some  portion  or all of the
deferred  tax assets  will not be  realized.  The  ultimate  realization  of the
deferred  income  tax  assets  depends  on the  Company's  ability  to  generate
sufficient  taxable income in the future.  Management has determined that, based
on the Company's  ability to generate  taxable income in two  consecutive  years
(1997 and 1996),  it is more likely than not that the Company  will  realize the
deferred tax assets.

         The  Company's  estimated  backlog for the next two  quarters of fiscal
year 1998 is almost $13.0 million  including a total of 6 contracts for the TTCT
Series  concrete  cooling  towers  and/or parts  totaling  $2.8  million.  These
contracts are scheduled for completion in the third quarter of 1998. Interest in
this  product  has   continued  to  increase  in  both  the  United  States  and
international  markets.  The  estimated  backlog for the TTMT Series  fiberglass
cooling  towers is $6.3  million.  $4.9 million is scheduled for delivery in the
third quarter and the balance in fourth  quarter 1998.  The Company  expects the
OKC plant to be 80%  operational in August 1998 and 100%  operational by the end
of the fiscal year. Rental tower backlog is over $3.8 million with substantially
all  scheduled for third  quarter  1998.  This will have a significant  positive
impact on third quarter operations.

     Six Months Ended May 31, 1998 Compared to Six Months Ended May 31, 1997

         For the six months ended May 31, 1998,  total tower revenues  decreased
to $9,915,823  from  $10,455,694  for the  comparable  period in the prior year.
During the  current  six month  period 41 percent of total  tower  revenues  was
derived from sales of 118 modular fiberglass cooling towers, 44 percent of total
tower revenues was derived from construction of the new modular concrete cooling
towers,  12 percent of total tower  revenues  was derived from rental of modular
fiberglass  cooling  towers,  and 3 percent of total tower  revenues was derived
from other tower revenue. In the comparable six month period in 1997, 75 percent
of total tower revenues was derived from sales of 193 modular cooling towers, 16
percent  of total  tower  revenues  was  derived  from  construction  of modular
concrete  towers,  3 percent of total tower  revenues was derived from rental of
modular cooling towers,  and 5 percent of total tower revenues were derived from
other tower revenue.  The decrease in fiberglass  tower revenues for 1998 is due
not only to the  decrease in the quantity of units sold but also to the sales of
smaller capacity, less expensive units. The decrease in the number of units sold
is due primarily to the delays in the  completion and occupancy of the OKC plant
combined with delays in the delivery of the manufacturing equipment and tooling.
It is estimated  that these delays will have a  significantly  smaller  negative
impact on the third quarter 1998. However, the Company has tried to minimize the
impact by continuing  to  aggressively  market and sell its TTMT series  modular
fiberglass  cooling tower which is continuing to be assembled in its  Chickasha,
Oklahoma  plant.  In addition to the delays,  the Company  entered into a rental
contract for 80 of the Company's largest modular fiberglass cooling towers. Over
70 of these towers had to be produced  during April and May for rental  start-up
beginning  in  June  1998.   Consequently   several  customer   deliveries  were
rescheduled  for third quarter 1998.  The rental  revenue from this large rental
project will be recognized  mostly in the third quarter of 1998. The increase in
concrete  tower  revenues is due to the  increase in the number and size of jobs
completed and in process. The increase in tower rentals is due to an increase in
the number of rental  contracts as well as an increase in contract  amount.  The
Company has been  focusing on  marketing  this  segment of the  business and has
significantly  increased the number of units  available  for rental.  Management
believes that the Company now has the largest  rental cooling tower fleet in the
industry.  Accordingly,  steady growth in rental tower revenues is  anticipated.
Other tower  revenue is down from the previous year due to the same reasons that
tower sales  decreased.  No licensing  agreements were finalized in the first or
second  quarters  of  fiscal  1998  although  negotiations  are  continuing  for
agreements in China and Northern  Europe.  Other  operating  revenue for the six
months  ended May 31,  1997,  consists of  technology  transfer  fees which were
realized  as a result of license  agreements  with Tecno  Procesos  Industriales
covering the Republic of Mexico.  These technology transfer fees demonstrate the
Company's ability to capitalize on the technology it develops. The Company is in
the  business of  developing  technology  for the  cooling  tower  industry  and
marketing that  technology,  either  directly or in the form of products such as
its TTMT Series cooling tower.

                                       -5-


<PAGE>


         The Company's cost of goods sold and  constructed  during the six month
period ended May 31, 1998,  was $9,121,219 or 92 percent of total tower revenues
as compared to $8,234,280 or 79 percent  during the  comparable  period in 1997.
The increase in cost of goods sold and constructed  during the second quarter of
1998 resulted from increased  construction costs of the modular concrete cooling
towers.  Overall  margin  decreased as a result of concrete  cooling  tower cost
overruns  mainly on two  projects,  and lower  margins were also incurred in the
modular  fiberglass cooling line due to the additional costs associated with the
plant,  equipment and tooling  delays.  However,  these decreases in margin were
partially  offset by an increase in rental  revenues,  which is a higher  margin
operation. Included in cost of goods sold for the six month period ended May 31,
1998, is $172,234 to retrofit and service towers  previously sold. This compares
to six month retrofit and warranty  costs of $249,200  during the same period in
1997. In 1995,  design changes were made and a complete  quality  control system
was  implemented  which  management  believes will control such  expenditures in
future periods.

         The six month period ended May 31, 1998 reflected a 62 percent increase
in general and  administrative  expenses  from $662,875 in 1997 to $1,074,304 in
1998.  The  increase is due mainly to the  addition of office  staff and related
expenses,  additional  expenses related to the OKC facility,  and an increase of
$125,000 in the allowance for doubtful accounts. Selling expenses increased from
$572,785 to  $888,350.  The  increase is due to  increased  sales and  marketing
efforts  for both the TTMT  Series  and the  concrete  modular  cooling  towers,
including  an increase  in sales staff and  expenses  related  primarily  to the
opening of direct domestic and international  sales offices.  Management expects
increased  investment in selling expenses to have a continued positive impact on
revenues in future  periods.  Research and development  expenses  decreased from
$268,150  in the first six months of 1997 to $195,171 in the first six months of
1998.  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 costs are  anticipated  to continue at
current levels.

         The  Company's  loss from  operations  for the six months ended May 31,
1998, was  $1,363,221 as compared to income from  operations of $987,604 for the
comparable period in the prior year. After interest expense, miscellaneous items
and income tax benefit,  the Company's net loss was $1,051,693 compared to a net
income of $680,965 for the six months ended May 31, 1997.

Liquidity and Capital Resources

       At May 31,  1998,  the  Company  had  working  capital of  $3,728,889  as
compared to working  capital of $6,307,697  at February 28, 1998.  The Company's
cash  flow  provided  by  (used  in)  its  operating,  investing  and  financing
activities during second quarter 1998 and 1997 are as follows:

       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.  Management  anticipates that the Company's operating
activities  will  require  cash  during  1998,  which  primarily  relates to the
anticipated  growth in  receivables  and inventory  levels to support  expanding
sales. 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.  Bringing  the  manufacturing
processes in-house will enable the Company to better manage inventory levels and
reduce costs when the new manufacturing facility is fully operational.  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  construction projects
will have a greater effect on working capital requirements in the future. At May
31,  1998,  costs in excess of billing and  estimated  earnings  on  uncompleted
contracts  were  $1,900,662  as compared to net costs in excess of billings  and
estimated  earnings  on  uncompleted  contracts  of  $509,749  at May 31,  1997.
Normally,  concrete  construction  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 $155,659 over
the next twelve months. In addition,  $955,194 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
1998  will be  related  to the  completion  of the new  manufacturing  facility,
construction of the new office facility in south Oklahoma City, and increases in
the rental fleet as necessary to meet demand. Management estimates the Company's
total investment in the new manufacturing facility will be $9 million, including
$3.5 million to equip the facility. As of May 31, 1998, the Company had incurred
substantially all the costs related to the manufacturing facility.  Construction
of the new office  facility was  commenced in April 1998 and should be completed
in December 1998. The  manufacturing  facility  includes  equipment to allow the
Company to produce parts used in the TTMT Series  cooling towers which have 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.

       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  1997.  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,  yielding net proceeds of  approximately  $5,467,000.  The Debentures bear
interest at 10 percent,  which is payable  semiannually,  and mature on June 10,
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  under  which a HUD  Section  108 loan in the  amount of
$1,250,000   is  available   to  the  Company  for  start-up   expenses  of  the
manufacturing  facility and associated working capital  requirements.  As of May
31, 1998, $1,225,025 of these funds had been advanced to the Company.  Initially
the loan  bears  interest  at 20 basis  points  above the LIBOR  rate,  adjusted
monthly,  and interest only is payable  quarterly.  When HUD provides  permanent
financing,  the interest  rate  becomes  fixed at the rate charged by HUD to the
City and  principal  and interest are payable  quarterly  based on an eight-year
amortization  period. The loan is collateralized by a second mortgage on the OKC
manufacturing facility.

       The Company has entered into an agreement with a lending  institution for
a  total  funding  of   $1,750,000   for  equipment  and  tooling  for  the  new
manufacturing  facility.  In November 1997, the Company  executed a note payable
for initial  funding of $731,890 and in December 1997,  the Company  executed an
additional  note payable for the second  funding in the amount of $442,974.  The
final funding was in March 1998.

       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 has been  increased to $6,500,000.  This  financing  replaced a
$2,000,000 line of credit payable to an individual.  The outstanding  balance at
May 31, 1998 was  $4,200,721.  Interest is payable monthly at a variable rate of
two basis points over national  prime rate.  The loan matures June 30, 1999. The
agreement is collateralized by certain accounts  receivable,  inventory,  rental
fleet and patents.  Also,  negotiations  are in process to further increase this
line of credit to help fund  increases in the Company's  rental fleet and growth
in accounts receivable and inventory.

       The  Company  has a line of credit  at  Chickasha  Bank in the  amount of
$400,000 for short-term  cash flow needs,  of which $357,000 was  outstanding at
May 31, 1998.  This line of credit matures April 1, 1999. The Company also has a
$1,200,000  credit  arrangement  with one of its major vendors to fund materials
purchased from the vendor of which  $1,138,000 was  outstanding  and included in
accounts payable at May 31, 1998.

       In April 1998, the Company  finalized a $2,000,000  construction loan for
the Oklahoma City office facility which is expected to cost  approximately  $2.1
million.  The loan  matures in April 1999 and bears  interest  at 9.5%,  payable
monthly.

       Due to the loss for the  first  half of 1998  combined  with the  capital
expenditures  to expand the rental  fleet,  the  Company  believes  it will need
additional   capital   resources  to  fund  its  operations   including  capital
requirements over the next four quarters. Accordingly, management is negotiating
for an increase in its credit facility as well as exploring other debt or equity
sources.  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

       Many existing computer programs use only two digits to identify a year in
the date field.  These programs were designed and developed without  considering
the impact of the upcoming  change in the century.  If not  corrected,  computer
applications  could fail or create erroneous results by or at the Year 2000. The
Company is in the process of  determining  whether  its  computer  programs  are
affected by the Year 2000 issue or whether the costs of making its systems  Year
2000 compliant or the  consequences  of failing to take necessary  actions would
have a  material  impact on the  Company's  financial  position  or  results  of
operations.  The Company is  currently  implementing  a new  financial  software
system that will cost approximately $100,000 which is Year 2000 compliant.

1997, with a check payable to the Oklahoma City Water Utilities Trust.

For your records, attached is a copy of the final amortization schedule based on

      Agreement with respect to this transaction are and shall be true, correct,

     the Collateral;

(b)   to pay reasonable  attorneys'  fees (at least 15% of the unpaid balance if

(c)   to pay promptly all taxes,  assessments,  license fees and other public or
      private  charges when levied or assessed  against the  Collateral  of this
      Security  Agreement,  and this obligation shall survive the termination of
      this Security Agreement;

(d)   that if a  certificate  of title be required or permitted  by law,  Debtor
      shall obtain such certificate with respect to the collateral,  showing the
      security  interest of Secured Party thereon and in any event do everything
      necessary  or  expedient  to reserve or perfect the  security  interest of
      Secured Party;

(e)   that  Debtor  will not  misuse,  fail to keep in good  repair,  secrete or
      without the prior written  consent of Secured  Party,  sell,  rent,  lend,
      encumber or transfer any of the Collateral notwithstanding Secured Party's
      right to Proceeds;

(f)   that  Secured  Party may enter upon  Debtor's  premises  or  wherever  the
      Collateral may be locate at any reasonable  time to inspect the Collateral
      and Debtor's books and records  pertaining to the  Collateral,  and Debtor
      shall assist Secured Party in making such inspection; and

(g)   that the  security  interest  granted  by Debtor to  Secured  Party  shall
      continue  effective  irrespective  of any  retaking or  redelivery  of any
      Collateral and  irrespective of the payment of the amount described in any
      Schedule  so long as there  are any  obligations  of any  kind,  including
      obligations  under  guaranties or  assignments,  owed by Debtor to Secured
      Party,  provided,- however, upon any assignment of this Security Agreement
      the Assignee- shall thereafter be deemed for the purpose of this Paragraph
      the Secured Party under this Security Agreement.

8. Insurance and Risk of Loss.

All risk of loss,  damage to or destruction of the Collateral shall at all times
be on Debtor.  Debtor will procure  forthwith  and maintain at Debtor's  expense
insurance against all risks of loss or physical damage to the Collateral for the
full  insurable  value thereof for the life of this Security  Agreement and such
other  insurance  thereon in amounts and against such risks as Secured Party may
specify, and shall promptly deliver each policy to Secured Party with a standard
long-form mortgagee endorsement attached thereto showing loss payable to secured
Party; and providing  Secured Party with not less than 30 days written notice of
cancellation;  each such  policy  shall be in form,  terms and  amount  and with
insurance carriers  satisfactory to Secured Party; Secured Party's acceptance of
Policies  in  lesser  amounts  or risks  shall  not be a waiver  of  Debtor's  I
foregoing  obligations.  As to Secured Party's interest in such policy no act or
omission of Debtor or any of its officers,  agents, employees or representatives
shall affect the obligations of the insurer to pay the full amount of any loss.


<PAGE>



Debtor hereby assigns to Secured Party any monies which may become payable under
any such policy of insurance and irrevocably  constitutes  and appoints  Secured
Party as Debtor's attorney n fact (a) to hold each original insurance policy (b)
to make,  settle and adjust claims under each policy of  insurance,  (c) to make
claims for any monies which may become payable under such and other insurance cm
the  Collateral  including  returned  or unearned  premiums,  and (d) to endorse
Debtor's  name on any check,  draft or other  instrument  received in payment of
claims or returned or unearned premiums under each policy and to apply the funds
to the payment of the indebtedness  owing to Secured Party;  provided,  however,
Secured Party is under no obligation to do any of the forgoing.

Should  Debtor fail to furnish such  insurance  policy to Secured  Party,  or to
maintain  such policy in full  force,  or to pay any premium in whole or in part
re1ating thereto,  then Secured Party,  without waiving or releasing any default
or  obligation by Debtor,  may (but shall be under no obligation  to) obtain and
maintain  insurance and pay the premium  therefor on behalf of Debtor and charge
the premium to Debtor's  indebtedness  under this Security  Agreement.  The full
amount of any such premium paid by Secured Party shall be payable by Debtor upon
demand,  and failure to pay same shall constitute an event of default under this
Security Agreement.

A very important element of this Security  Agreement is that Debtor make all its
payments  promptly as agreed upon. It is essential that the Collateral remain in
good  condition and adequate  security for the  indebtedness.  The following are
events of default under this Security  Agreement  which will allow Secured Party
to take such action  under this  Paragraph  and under  Paragraph  10 as it deems
necessary:

(a)   any of Debtor's  obligations  to Secured  Party under any  agreement  with
      Secured Party is not paid promptly when due;

(b)   Debtor breaches any warranty or provision hereof, or of any note or of any
      other  instrument  or agreement  de1ivered  by Debtor to Secured  Party in
      connection with this or any other transaction;

(C) Debtor dies, becomes insolvent or ceases to do business as a going concern:

(d)   It is determined that Debtor has given Secured Party materially misleading
      information regarding its financial condition;

(e)   any of the Collateral is lost or destroyed;

(f)   a complaint in  bankruptcy or for  arrangement  or  reorganization  or for
      relief under any  insolvency  law is filed by or against  Debtor or Debtor
      admits its inability to pay its debts as they mature

(g) property of Debtor is attached or a receiver is appointed for Debtor;

(h)   whenever  Secured Party in good faith  believes the prospect of payment or
      performance  is  impaired  or in good faith  believes  the  Collateral  is
      insecure;.

(i)   any  guarantor  surety or  endorser  for Debtor  dies or  defaults  in any
      obligation  or  liability to Secured  Party or any  guaranty  contained in
      connection with this transaction is terminated or breached; or


<PAGE>



(j)  if a  default,  event of default or breach by Debtor  shall  occur,  or any
     event  occurs  which  with the  giving of notice or passage of time or both
     would  constitute a default or event of default,  under any loan agreement,
     security  agreement,  financing  arrangement,  lease agreement,  indenture,
     promissory note, guaranty,  or any other document,  agreement or instrument
     evidencing or securing a debt or obligation of Debtor (each  individually a
     "Loan  Agreement" and  collectively  "Loan  Agreements")  with or to Finova
     Capital,  or any affiliate,  subsidiary or parent of Finova Capital, or any
     successors and assigns thereto or under a Loan Agreement  which  refinances
     the  indebtedness  or  obligations  evidenced  by the Finova  Capital  Loan
     Agreement or replaces the Finova Capital Loan Agreement.


                                                                             CDW
                                                                       _________
                                                                        Initials




If Debtor  shall be in default  hereunder,  the  indebtedness  described in each
Schedule and all other  indebtedness then owing by Debtor to Secured Party under
this or any other present or future agreement (collectively, the "Indebtedness")
shall,  if Secured  Party shall so elect,  become  immediately  due and payable.
After acceleration;

(a)   the unpaid principal balance of the indebtedness described in any Schedule
      in which interest has been precomputed  shall bear interest at the rate of
      18% per annum (or, if less,  the maximum rate permitted by law) until paid
      in full; arid

(b)   the unpaid principal balance of the indebtedness described in any Schedule
      in which interest has not been precomputed shall bear interest at the same
      rate as before acceleration until paid in full.

Indebtedness, by acceleration of the maturity thereof or otherwise, be obligated
to pay any interest in excess of the amount permitted by law Any acceleration of
the  Indebtedness,  if  elected  by  Secured  Party,  shall  be  subject  to all
applicable  laws,  including  laws  relating  to rebates and refunds of unearned
charges.

10. Secured Party's Remedies After Default; Consent to Enter Premises.

Upon Debtor's default and at any time thereafter, subject to Debtor's right to a
30 day cure period  (referencing  item 9(a) only),  Secured Party shall have all
the rights and remedies of a secured party under the Uniform Commercial Code and
any other applicable laws, including the right to any deficiency remaining after
disposition  of the  Collateral  for which Debtor  hereby agrees to remain fully
liable.  Debtor agrees that Secured Party,  by itself or its agent,  may without
notice to any person and without  judicial  process of any kind,  enter into any
premises or upon any land owned,  leased or otherwise under the real or apparent

Secured Party believes the Collateral may be, and  disassemble,  render unusable
and or repossess all or any item of the Collateral, disconnecting and separating
all  Collateral  from any other property and using all force  necessary.  Debtor
expressly  waives all  further  rights to  possession  of the  Collateral  after
default.  Secured Party may require Debtor to assemble the Collateral and return
it to  Secured  Party at a place to be  designated  by  Secured  Party  which is
reasonably convenient to both parties.

Secured  Party may sell or lease the  Collateral  at a time and  location of its
choosing  provided  that  the  Secured  Party  acts  in  good  faith  and  in  a
commercially reasonable manner. Secured Party will give Debtor reasonable notice
of the time and place of any public sale of the  Collateral or of the time after
which any private sale or any other intended disposition of the Collateral is to
be the outstanding  principal  balance If not prohibited by law) and other legal
expenses. Debtor under' tends that Secured Party's rights are cumulative and not
alternative.

11.   Waiver of Defaults; Agreement Inclusive.

Secured Party may in its sole discretion  waive a default,  or cure, at Debtor's
expense, a default.  Any such waiver in a particular Instance or of a particular
default  shall not be a waiver of other  defaults or the same kind of default at
another  time.  No  modification  or change in this  Security  Agreement  or any
related note  instrument or agreement shall bind Secured Party unless in writing
signed by Secured Party. No oral agreement shall be binding.

12.   Financing Statements; Certain Expenses.

If  permitted  by law,  Debtor  authorizes  Secured  Party  to file a  financing
statement  with respect to the Collateral  signed only by Secured Party,  and to
file a carbon, photograph or other reproduction of this Security Agreement or of
a financing statement.  At the request of Secured Party, Debtor will execute any
financing statements,  agreements or documents,  in form satisfactory to Secured
Party which  Secured  Party may deem  necessary or  advisable  to establish  and
maintain a perfected  security  interest in the Collateral and will pay the cost
of filing or  recording  the same in all  public  offices  deemed  necessary  or
advisable  by Secured  Party.  Debtor also agrees to pay all costs and  expenses
incurred by Secured Party in conducting UCC, tax or other lien searches  against
the debtor or the Collateral and such other fees as may be agreed.

      such claim,  defense,  setoff or counterclaim  against  Assignee,  Secured
      Party hereby agreeing to remain responsible therefor;

(c)   Secured Party shall not be Assignee's agent for any purpose and shall have
      no  authority to change or modify this  Security  Agreement or any related
      document or instrument; and

Principal Amount: $6,500,000.00
Initial Rate: 10.500%
Date of Note: April 17,1998

PROMISE TO PAY. Tower Tech,  Inc.  ("Borrower")  promises to pay to Southwestern
Bank & Trust Company ("Lender"),  or order, in lawful money of the United States
of America,  the principal  amount of Six Million Five Hundred Thousand & 00/100
Dollars ($6,500,000.00) or so much as may be outstanding, together with interest
on the unpaid outstanding  principal balance of each advance.  Interest shall be
calculated  from the date of each advance until  repayment of each advance.  The
maximum  principal  amount of this Note  shall be reduced  to  $5,000,000.00  on
December 31, 1998, and, if necessar6, Borrower shall make a mandatory prepayment
as set forth below.

PAYMENT.  Borrower will pay this loan on demand, or if no demand is made, in one
payment of all  outstanding  principal plus all accrued unpaid  interest on June
30,1999.  In addition,  Borrower  will pay regular  monthly  payments of accrued
unpaid interest  beginning April 30,1998,  and all subsequent  interest payments
are due on the same day of each  month  after  that.  Interest  on this  Note is
computed on a 365/360 simple interest  basis;  that is, by applying the ratio of
the annual interest rate over a year of 360 days,  multiplied by the outstanding
principal balance, multiplied by the actual number of days the principal balance
is outstanding.  Borrower will pay Lender at Lender's  address shown above or at
such other place as Lender may designate in writing.  Unless otherwise agreed or
required by applicable  law,  payments  will be applied first to accrued  unpaid
interest,  then to principal,  and any remaining amount to any unpaid collection
costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on  changes in an  independent  index  which is the  National
Prime (the  "Index").  The Index is not  necessarily  the lowest rate charged by
Lender on its loans.  If the Index becomes  unavailable  during the term of this
loan,  Lender may designate a substitute index after notice to Borrower.  Lender
will tell  Borrower the current  Index rate upon  Borrower's  request.  Borrower
understands  that  Lender  may make  loans  based on  other  rates as well.  The
interest  rate  change  will not occur  more  often  than  each  day.  The Index
currently  is 8.500% per annum.  The  Interest  rate to be applied to the unpaid
principal balance of this Note will be at a rate of 2.000 percentage points over
the Index,  resulting In an Initial rate of 10.500% per annum.  NOTICE: Under no
circumstances  will the interest rate on this Note be more than the maximum rate
allowed by applicable law.

PREPAYMENT;  MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Note,  Borrower  understands  that Lender is entitled to a minimum interest
charge of $7.50.  Other than Borrower's  obligation to pay any minimum  interest
charge,  Borrower  may pay  without  penalty all or a portion of the amount owed
earlier than it is due. Early  payments will not,  unless agreed to by Lender in
writing,  relieve Borrower of Borrower's obligation to continue to make payments
of accrued unpaid interest. Rather, they will reduce the principal balance due.

DEFAULT.  Borrower  will be in  default  if any of the  following  happens:  (a)
Borrower  fails to make any payment when due.  (b)  Borrower  breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement  related to this Note, or in any other  agreement or loan Borrower
has with Lender.  (c)  Borrower  defaults  under any loan,  extension of credit,
security  agreement,  purchase or sales agreement,  or any other  agreement,  in
favor of any  other  creditor  or  person  that  may  materially  affect  any of
Borrower's  property  or  Borrower's  ability  to  repay  this  Note or  perform
Borrower's obligations under this Note or any of the Related Documents.  (d) Any
representation  or  statement  made or  furnished  to Lender by  Borrower  or on
Borrower's  behalf is false or misleading in any material  respect either now or
at the time made or furnished.  (e) Borrower  becomes  insolvent,  a receiver is
appointed for any part of Borrower's property,  Borrower makes an assignment for
the benefit of creditors,  or any proceeding is commenced  either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's  property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any  guarantor  dies or any of the other  events  described  in this default
section  occurs  with  respect to any  guarantor  of this Note or any  guarantor
seeks,  claims or otherwise attempts to limit, modify or revoke such guarantor's
guarantee  of this Note.  (h) A material  adverse  change  occurs in  Borrower's
financial  condition,  or Lender believes the prospect of payment or performance

applicable  law, to charge or setoff all sums owing on this Note against any and

interest in and hereby assigns, conveys, delivers, pledges, and transfers all of
Grantor's  right,  title and interest in and to Grantor's  accounts  with Lender
(whether checking, savings, or some other account),  including all accounts held

the grant of a security interest would be prohibited by law. Grantor  authorizes
Lender,  to the extent  permitted  by  applicable  law,  to charge or setoff all
Indebtedness against any and all such accounts.

OBLIGATIONS OF GRANTOR.  Grantor warrants and covenants to Lender as follows:

Perfection  of  Security  interest.  Grantor  agrees to execute  such  financing
statements and to take whatever other actions are requested by Lender to perfect
and  continue  Lender's  security  interest in the  Collateral.  Upon request of
Lender,  Grantor will deliver to Lender any and all of the documents  evidencing
or constituting the Collateral, and Grantor will note Lender's interest upon any
and all  chattel  paper if not  delivered  to Lender for  possession  by Lender.
Grantor  hereby  appoints  Lender as its  irrevocable  attorney-in-fact  for the
purpose of  executing  any  documents  necessary  to perfect or to continue  the
security interest granted in this Agreement. Lender may at any time, and without
further  authorization  from  Grantor,  file a  carbon,  photographic  or  other
reproduction  of any  financing  statement  or of  this  Agreement  for use as a
financing  statement.  Grantor  will  reimburse  Lender for all expenses for the
perfection and the continuation of the perfection of Lender's  security interest
in the  Collateral.  Grantor  promptly  will notify  Lender before any change in
Grantor's  name  including any change to the assumed  business names of Grantor.
This is a continuing  Security Agreement and will continue in effect even though
all or any part of the Indebtedness is paid in full and even though for a period
of time Grantor may not be indebted to Lender.

No Violation.  The execution and delivery of this Agreement will not violate any
law or  agreement  governing  Grantor or to which  Grantor  is a party,  and its
certificate or articles of incorporation  and bylaws do not prohibit any term or
condition of this Agreement.

Enforceability of Collateral. To the extent the Collateral consists of accounts,
chattel  paper,  or  general  intangibles,  the  Collateral  is  enforceable  in
accordance  with its terms,  is  genuine,  and  complies  with  applicable  laws
concerning  form,  content  and manner of  preparation  and  execution,  and all
persons  appearing to be obligated on the Collateral have authority and capacity
to contract and are in fact obligated as they appear to be on the Collateral.

Location of the  Collateral.  Grantor,  upon request of Lender,  will deliver to
Lender  in form  satisfactory  to  Lender  a  schedule  of real  properties  and
Collateral  locations  relating  to  Grantor's  operations,   including  without
limitation  the  following:  (a) all real property  owned or being  purchased by
Grantor;  (b) all real  property  being  rented or leased  by  Grantor;  (c) all
storage facilities owned, rented,  leased, or being used by Grantor; and (d) all
other properties  where Collateral is or may be located.  Except in the ordinary
course  of its  business,  Grantor  shall not  remove  the  Collateral  from its
existing locations without the prior written consent of Lender.

Removal of  Collateral.  Grantor shall keep the Collateral (or to the extent the
Collateral  consists  of  intangible  property  such as  accounts,  the  records
concerning the  Collateral) at Grantor's  address shown above,  or at such other
locations as are  acceptable  to Lender.  Except in the  ordinary  course of its
business,  including  the  sales of  inventory,  Grantor  shall not  remove  the
Collateral  from its existing  locations  without the prior  written  consent of
Lender. To the extent that the Collateral consists of vehicles,  or other titled
property,  Grantor  shall not take or permit  any  action  which  would  require
application  for  certificates  of title for the  vehicles  outside the State of
Oklahoma, without the prior written consent of Lender.

Transactions  Involving  Collateral.  Except  for  inventory  sold  or  accounts
collected in the ordinary course of Grantor's business,  Grantor shall not sell,
offer to sell, or otherwise transfer or dispose of the Collateral. While Grantor
is not in default under this Agreement,  Grantor may sell inventory, but only in
the ordinary course of its business and only to buyers who qualify as a buyer in
the  ordinary  course of business.  A sale in the  ordinary  course of Grantor's
business does not include a transfer in partial or total  satisfaction of a debt
or any bulk sale.  Grantor  shall not pledge,  mortgage,  encumber or  otherwise
permit the Collateral to be subject to any lien, security interest, encumbrance,
or charge,  other than the security  interest  provided  for in this  Agreement,
without the prior written consent of Lender.  This includes  security  interests
even if junior in right to the security  interests granted under this Agreement.
Unless waived by Lender,  all proceeds from any  disposition  of the  Collateral
(for  whatever  reason)  shall be held in trust  for  Lender  and  shall  not be
commingled with any other funds;  provided  however,  this requirement shall not
constitute  consent by Lender to any sale or other  disposition.  Upon  receipt,
Grantor shall immediately deliver any such proceeds to Lender.

Title.  Grantor  represents  and  warrants  to  Lender  that it  holds  good and
marketable title to the Collateral, free and clear of all liens and encumbrances
except for the lien of this Agreement.  No financing  statement  covering any of
the  Collateral  is on file in any public  office other than those which reflect
the  security  interest  created  by  this  Agreement  or to  which  Lender  has
specifically  consented.  Grantor shall defend Lender's rights in the Collateral
against the claims and demands of all other persons.

Collateral  Schedules  and  Locations.  Insofar as the  Collateral  consists  of
inventory,  Grantor shall deliver to Lender,  as often as Lender shall  require,
such lists,  descriptions,  and  designations  of such  Collateral as Lender may
require to identify the nature,  extent,  and location of such Collateral.  Such
information  shall be  submitted  for  Grantor and each of its  subsidiaries  or
related companies.

Maintenance  and inspection of  Collateral.  Grantor shall maintain all tangible
Collateral  in good  condition  and  repair.  Grantor  will not commit or permit
damage to or destruction of the Collateral or any part of the Collateral. Lender
and its  designated  representatives  and  agents  shall  have the  right at all
reasonable times to examine, inspect, and audit the Collateral wherever located.
Grantor  shall  immediately  notify  Lender of all cases  involving  the return,
rejection,  repossession, loss or damage of or to any Collateral; of any request
for credit or  adjustment  or of any other  dispute  arising with respect to the
Collateral;  and generally of all happenings and events affecting the Collateral
or the value or the  amount  of the  Collateral.  Grantor  will  furnish  Lender
information  adequate to identify with accuracy all  Collateral and will deliver
to Lender upon request true copies of all evidence Grantor possesses  concerning
the  Collateral  and its location.  Grantor at all times will maintain  adequate
books and records concerning the Collateral.

Taxes,  Assessments and Liens. Grantor will pay when due all taxes,  assessments
and liens upon the Collateral,  its use or operation,  upon this Agreement, upon
any promissory  note or notes  evidencing the  Indebtedness,  or upon any of the
other Related  Documents.  Grantor may withhold any such payment or may elect to
contest  any  lien  if  Grantor  is in  good  faith  conducting  an  appropriate
proceeding to contest the obligation to pay and so long as Lender's  interest in
the Collateral is not jeopardized in Lender's sole opinion. If the Collateral is
subjected to a lien which is not discharged  within  fifteen (15) days,  Grantor
shall  deposit with Lender cash,  a  sufficient  corporate  surety bond or other
security  satisfactory  to Lender  in an  amount  adequate  to  provide  for the
discharge of the lien plus any interest, costs, attorneys' fees or other charges
that could accrue as a result of foreclosure or sale of the  Collateral.  In any
contest  Grantor  shall  defend  itself and Lender and shall  satisfy  any final
adverse judgment before enforcement  against the Collateral.  Grantor shall name
Lender as an additional  obligee under any surety bond  furnished in the contest
proceedings.

Compliance with  Governmental  Requirements.  Grantor shall comply promptly with
all laws, ordinances, rules and regulations of all governmental authorities, now
or hereafter in effect, applicable to the ownership, production, disposition, or
use of the Collateral. Grantor may contest in good faith any such law, ordinance
or  regulation  and  withhold   compliance  during  any  proceeding,   including
appropriate appeals, so long as Lender's interest in the Collateral, in Lender's
opinion, is not jeopardized.

Hazardous Substances.  Grantor represents and warrants that the Collateral never
has been,  and  never  will be so long as this  Agreement  remains a lien on the
Collateral,  used  for the  generation,  manufacture,  storage,  transportation,
treatment,  disposal,  release or threatened  release of any hazardous  waste or
substance,  as  those  terms  are  defined  in the  Comprehensive  Environmental
Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C. Section
9601, et seq.  ("CERCLA"),  the Superfund  Amendments and Reauthorization Act of
1986, Pub. L. No. 9~99 ("SARA"), the Hazardous Materials  Transportation Act, 49
U.S.C.  Section 1801, et seq.,  the Resource  Conservation  and Recovery Act, 42
U.S.C.  Section 6901, et seq., or other applicable state or Federal laws, rules,
or regulations  adopted  pursuant to any of the foregoing.  The terms "hazardous
waste"  and  "hazardous  substance"  shall  also  include,  without  limitation,
petroleum and petroleum  by-products or any fraction  thereof and asbestos.  The
representations  and  warranties  contained  herein are based on  Grantor's  due
diligence in  investigating  the Collateral for hazardous wastes and substances.
Grantor  hereby (a) releases  and waives any future  claims  against  Lender for
indemnity or  contribution  in the event Grantor  becomes  liable for cleanup or
other costs under any such laws,  and (b) agrees to indemnify  and hold harmless
Lender  against  any and all claims and losses  resulting  from a breach of this
provision of this  Agreement.  This  obligation  to indemnify  shall survive the
payment of the Indebtedness and the satisfaction of this Agreement.

Maintenance of Casualty Insurance.  Grantor shall procure and maintain all risks
insurance,  including  without  limitation  fire,  theft and liability  coverage
together  with such other  insurance  as Lender may require  with respect to the
Collateral,  in form,  amounts,  coverages  and basis  reasonably  acceptable to
Lender and issued by a company or  companies  reasonably  acceptable  to Lender.
Grantor,  upon  request of Lender,  will deliver to Lender from time to time the
policies or certificates of insurance in form satisfactory to Lender,  including
stipulations that coverages will not be cancelled or diminished without at least
ten (10) days' prior written  notice to Lender and not including any  disclaimer
of the  insurer's  liability for failure to give such a notice.  Each  insurance
policy also shall  include an  endorsement  providing  that coverage in favor of
Lender  will not be  impaired  in any way by any act,  omission  or  default  of
Grantor or any other person.  In connection with all policies covering assets in
which  Lender  holds or is offered a security  interest,  Grantor  will  provide
Lender with such loss payable or other  endorsements  as Lender may require.  If
Grantor at any time fails to obtain or maintain any insurance as required  under
this Agreement, Lender may (but shall not be obligated to) obtain such insurance
as  Lender  deems  appropriate,  including  if it so  chooses  "single  interest
insurance," which will cover only Lender's interest in the Collateral.

Application of Insurance  Proceeds.  Grantor shall promptly notify Lender of any
loss or damage to the Collateral. Lender may make proof of loss if Grantor fails
to do so within fifteen (15) days of the casualty. All proceeds of any insurance
on the Collateral,  including accrued proceeds thereon,  shall be held by Lender
as part of the  Collateral.  If Lender  consents to repair or replacement of the
damaged or  destroyed  Collateral,  Lender  shall,  upon  satisfactory  proof of
expenditure,  pay or reimburse Grantor from the proceeds for the reasonable cost
of repair or restoration. If Lender does not consent to repair or replacement of
the Collateral,  Lender shall retain a sufficient  amount of the proceeds to pay
all of the  Indebtedness,  and shall pay the  balance to Grantor.  Any  proceeds
which have not been  disbursed  within six (6) months  after  their  receipt and
which Grantor has not committed to the repair or  restoration  of the Collateral
shall be used to prepay the Indebtedness.

Insurance Reserves.  Lender may require Grantor to maintain with Lender reserves
for payment of insurance  premiums,  which  reserves shall be created by monthly
payments  from Grantor of a sum estimated by Lender to be sufficient to produce,
at least  fifteen (15) days before the premium due date,  amounts at least equal
to the  insurance  premiums to be paid.  If fifteen (15) days before  payment is
due,  the  reserve  funds are  insufficient,  Grantor  shall upon demand pay any
deficiency  to Lender.  The  reserve  funds shall be held by Lender as a general
deposit and shall  constitute a  non-interest-bearing  account  which Lender may
satisfy by payment of the insurance  premiums  required to be paid by Grantor as
they become due.  Lender does not hold the reserve  funds in trust for  Grantor,
and Lender is not the agent of Grantor  for  payment of the  insurance  premiums
required to be paid by Grantor.  The  responsibility for the payment of premiums
shall remain Grantor's sole responsibility.

Insurance  Reports.  Grantor,  upon request of Lender,  shall  furnish to Lender
reports on each existing policy of insurance  showing such information as Lender
may reasonably request including the following: (a) the name of the insurer; (b)
the risks insured;  (c) the amount of the policy; (d) the property insured;  (e)
the then current value on the basis of which insurance has been obtained and the
manner of determining that value; and (f) the expiration date of the policy.  In
addition,  Grantor  shall upon  request by Lender  (however  not more often than
annually) have an independent  appraiser  satisfactory to Lender  determine,  as
applicable, the cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have possession of the
tangible  personal property and beneficial use of all the Collateral and may use
it in any lawful  manner not  inconsistent  with this  Agreement  or the Related
Documents,  provided that Grantor's right to possession and beneficial use shall
not apply to any  Collateral  where  possession  of the  Collateral by Lender is
required by law to perfect Lender's  security  interest in such  Collateral.  If
Lender at any time has possession of any Collateral,  whether before or after an
Event of Default,  Lender shall be deemed to have exercised  reasonable  care in
the custody and  preservation  of the Collateral if Lender takes such action for
that purpose as Grantor shall request or as Lender, in Lender's sole discretion,
shall deem appropriate under the circumstances, but failure to honor any request
by Grantor shall not of itself be deemed to be a failure to exercise  reasonable
care.  Lender shall not be required to take any steps  necessary to preserve any
rights in the  Collateral  against prior  parties,  nor to protect,  preserve or
maintain any security interest given to secure the ~

EXPENDITURES  BY LENDER.  If not  discharged  or paid when due,  Lender may (but
shall  not  be  obligated  to)  discharge  or pay  any  amounts  required  to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes,  liens,  security interests,  encumbrances,  and other claims, at any
time  levied or  placed on the  Collateral.  Lender  also may (but  shall not be
obligated  to) pay all  costs  for  insuring,  maintaining  and  preserving  the

Accelerate indebtedness.  Lender may declare the entire Indebtedness,  including
any prepayment  penalty which Grantor would be required to pay,  immediately due
and payable, without notice.

Assemble Collateral.  Lender may require Grantor to deliver to Lender all or any
portion  of the  Collateral  and any and all  certificates  of title  and  other

the following rights and remedies  regarding the appointment of a receiver:  (a)
Lender may have a receiver  appointed as a matter of right, (b) the receiver may

by this Agreement.

Collect Revenues,  Apply Accounts.  Lender, either itself or through a receiver,
may collect the  payments,  rents,  income,  and revenues  from the  Collateral.
Lender may at any time in its discretion  transfer any  Collateral  into its own
name or that of its  nominee  and  receive  the  payments,  rents,  income,  and
revenues  therefrom and hold the same as security for the  Indebtedness or apply
it to payment of the  Indebtedness  in such  order of  preference  as Lender may
determine.  Insofar as the Collateral consists of accounts, general intangibles,
insurance policies,  instruments,  chattel paper,  chooses in action, or similar
property, Lender may demand, collect, receipt for, settle,  compromise,  adjust,
sue for,  foreclose,  or realize  on the  Collateral  as Lender  may  determine,

of mail addressed to Grantor;  change any address to which mail and payments are

Lender may obtain a judgment against Grantor for any deficiency remaining on the
Indebtedness  due to Lender after  application of all amounts  received from the
exercise of the rights provided in this Agreement. Grantor shall be liable for a
deficiency  even if the  transaction  described in this  subsection is a sale of
accounts or chattel paper.

Other  Rights and  Remedies.  Lender shall have all the rights and remedies of a
secured creditor under the provisions of the Uniform  Commercial Code, as may be
amended from time to time.  In addition,  Lender shall have and may exercise any
or all other  rights and remedies it may have  available  at law, in equity,  or
otherwise.

Cumulative Remedies.  All of Lender's rights and remedies,  whether evidenced by
this  Agreement  or the  Related  Documents  or by any other  writing,  shall be
cumulative and may be exercised  singularly or concurrently.  Election by Lender
to pursue any remedy  shall not  exclude  pursuit  of any other  remedy,  and an
election  to make  expenditures  or to take action to perform an  obligation  of
Grantor under this  Agreement,  after  Grantor's  failure to perform,  shall not
affect Lender's right to declare a default and to exercise its remedies.

Lender's rights and remedies under this Agreement or any other agreement between
the  parties.  All  rights and  remedies  of Lender  are  cumulative  and may be
exercised singularly or concurrently, and the exercise of any one or more remedy
will not be a waver of any other. No waiver,  change,  modification or discharge
of any of Lender's rights or of Grantor's duties as so specified or allowed will
be  effective  unless in  writing  and  signed by a duly  authorized  officer of
Lender,  and any such waiver  will not be a bar to the  exercise of any right or
remedy on any  subsequent  default.  Lender  shall not be liable for  failure to

omission on the part of Lender.

waiver of such right or any other  right.  A waiver by Lender of a provision  of
this  Agreement  shall not  prejudice or  constitute a waiver of Lender's  right
otherwise to demand strict compliance with that provision or any other provision
of this Agreement.  No prior waiver by Lender, nor any course of dealing between
Lender and  Borrower,  or between  Lender and any  Grantor,  shall  constitute a
waiver of any of  Lender's  rights or of any  obligations  of Borrower or of any
Grantor  as to any  future  transactions.  Whenever  the  consent  of  Lender is
required  under this  Agreement,  the  granting of such consent by Lender in any

<PAGE>


DEFINITIONS:  As used on page 1, "X" means the terms  that  apply to this  loan.
"I," "me" or "my" means each  Borrower who signs this note and each other person
or legal entity (including  guarantors,  endorsers,  and sureties) who agrees to
pay this note (together  referred to as "us").  "You" or "your" means the Lender
and its  successors and assigns.  APPLICABLE  LAW: The law of the State in which
you are located  will govern this note.  Any term of this note which is contrary
to applicable  law will not be  effective,  unless the law permits you and me to
agree to such a variation. If any provision of this agreement cannot be enforced
according  to its terms,  this fact will not affect  the  enforceability  of the
remainder of this  agreement.  No  modification  of this  agreement  may be made
without your express written consent. T ime is of the essence in this agreement.
PAYMENTS:  Each  payment I make on this note will first  reduce the amount I owe
you for charges which are neither interest nor principal.  The remainder of each
payment will then reduce accrued unpaid interest, and then unpaid principal.  If
you and I agree to a different  application  of payments,  we will  describe our
agreement  on this note.  I may prepay a part of, or the entire  balance of this
loan  without  penalty,  unless we specify  to the  contrary  on this note.  Any
partial  prepayment will not excuse or reduce any later scheduled  payment until
this note is paid in full (unless,  when I make the prepayment,  you and I agree
in  writing  to the  contrary).  INTEREST:  Interest  accrues  on the  principal
remaining  unpaid  from  time to time,  until  paid in full.  If I  receive  the
principal  in more than one advance,  each  advance will start to earn  interest
only when I receive the advance. The interest rate in effect on this note at any
given  time  will  apply  to  the  entire  principal   advanced  at  that  time.
Notwithstanding  anything to the contrary,  I do not agree to pay and you do not
intend to charge any rate of interest  that is higher  than the maximum  rate of
interest you could charge under  applicable law for the extension of credit that
is agreed to here (either before or after  maturity).  If any notice of interest
accrual is sent and is in error,  we  mutually  agree to correct  it, and if you
actually collect more interest than allowed by law and this agreement, you agree
to refund it to me.  INDEX  RATE:  The index  will  serve  only as a device  for
setting the rate on this note. You do not guarantee by selecting this index,  or
the  margin,  that the rate on this note will be the same rate you charge on any
other  loans or class of loans to me or other  borrowers.  ACCRUAL  METHOD:  The
amount of  interest  that I will pay on this loan will be  calculated  using the
interest rate and accrual  method stated on page 1 of this note. For the purpose
of interest calculation, the accrual method will determine the number of days in
a "year."  If no  accrual  method  is  stated,  then you may use any  reasonable
accrual  method for  calculating  interest.  POST MATURITY RATE: For purposes of
deciding  when the "Post  Maturity  Rate"  (shown on page 11  applies,  the term
"maturity" means the date of the last scheduled  payment  indicated on page 1 of
this note or the date you accelerate payment on the note,  whichever is earlier.
SINGLE  ADVANCE  LOANS:  If this is a single advance loan, you and I expect that
you will make only one advance of principal.  However, you may add other amounts
to the principal if you make any payments  described in the "PAYMENTS BY LENDER"
paragraph below. MULTIPLE ADVANCE LOANS: If this is a multiple advance loan, you
and I expect that you will make more than one advance of  principal.  If this is
closed end  credit,  repaying  a part of the  principal  will not  entitle me to
additional  credit.  PAYMENTS  BY LENDER:  If you are  authorized  to pay, on my
behalf,  charges I am  obligated to pay (such as property  insurance  premiums),
then you may treat those  payments  made by you as advances  and add them to the
unpaid  principal  under this note, or you may demand  immediate  payment of the
charges.  SET-OFF: I agree that you may Set off any amount due and payable under
this note against any right I have to receive money from you.
    "Right to receive money from you," means:
    (1) any deposit account balance I have with you;
    (2) any money owed to me on an item  presented to you or in your  possession
    for  collection  or  exchange;  and (3) any  repurchase  agreement  or other
    nondeposit  obligation.  "Any amount due and payable  under this note" means
    the total amount of which you are entitled to demand payment under the terms
    of this note at the time you Set off.  This total  includes  any balance the
    due date for which you properly  accelerate  under this note. If my right to
    receive  money from you is also  owned by someone  who has not agreed to pay
    this note, your right of set-off will apply to my interest in the obligation
    and to any other amounts I could withdraw on my sole request or endorsement.
    Your right of set-off does not apply to an account or other obligation where
    my  rights  are only as a  representative.  It also  does  not  apply to any
    Individual Retirement Account or other tax-deferred  retirement account. You
    will not be liable for the  dishonor of any check when the  dishonor  occurs
    because you set off this debt  against any of my  accounts.  I agree to hold
    you harmless  from any such claims  arising as a result of your  exercise of
    your right of set-off.
REAL ESTATE OR RESIDENCE  SECURITY:  If this note is secured by real estate or a
residence  that is  personal  properly,  the  existence  of a  default  and your
remedies for such a default will be determined  by applicable  law, by the terms
of any Separate instrument creating the security interest and, to the extent not
prohibited  by law  and not  contrary  to the  terms  of the  separate  security
instrument, by the "Default" and Remedies" paragraphs herein. DEFAULT: I will be
in  default  if any  one or more of the  following  occur:  (1) I fail to make a
payment on time or in the amount due; (2) I fail to keep the  property  insured,
if required;  (3) I fail to pay, or keep any promise, on any debt or agreement I
have with you; (4) any other creditor of mine attempts to collect any debt I owe
him through  court  proceedings;  (5) I die, am  declared  incompetent,  make an
assignment for the benefit of creditors,  or become insolvent (either because my
liabilities exceed my assets or I am unable to pay my debts as they become due);
(6) I make any written  statement or provide any financial  information  that is
untrue  or  inaccurate  at the  time  it was  provided;  (7) 1 do or  fail to do
something which causes you to believe that you will have  difficulty  collecting
the amount lowe you; (8) any  collateral  securing this note is used in a manner
or for a purpose which threatens confiscation by a legal authority; (9) I change
my name or assume an additional  name without first  notifying you before making
such a change;  (10) I fail to plant,  cultivate and harvest crops in due season
if I am a producer of crops;  (11) any loan proceeds are used for a purpose that
will  contribute  to  excessive  erosion  of  highly  erodible  land  or to  the
conversion  of  wetlands  to  produce  an  agricultural  commodity,  as  further
explained  in 7 C.F.R.  Part 1940,  Subpart G, Exhibit M.  REMEDIES:  If I am in
default on this note you have, but are not limited to, the following remedies:
(1)  You  may  demand  immediate  payment  of  all I owe  you  under  this  note
     (principal, accrued unpaid interest and other accrued charges)
(2)  You may set off this debt  against any right I have to the payment of money
     from you, subject to the terms of the "Set-Off" paragraph herein.
(3)  You may demand security,  additional security,  or additional parties to be
     obligated to pay this note as a condition for not using any other remedy.
(4)  You may refuse to make advances to me or allow purchases on credit by me.
(5)  You may use any remedy you have under state or federal  law.  By  selecting
     any one or more of these  remedies  you do not give up your  right to later
     use any other  remedy.  By  waiving  your right to declare an event to be a
     default,  you do not  waive  your  right to later  consider  the event as a
     default if it continues or happens again.

COLLECTION  COSTS AND  ATTORNEY'S  FEES: I agree to pay all costs of collection,
replevin or any other or similar  type of cost if I em in default.  In addition,
if you hire an  attorney to collect  this note,  I also agree to pay any fee you
incur with such attorney  plus court costs (except where  prohibited by law). To
the extent  permitted by the United States  Bankruptcy Code, I also agree to pay
the  reasonable  attorney's  fees and costs you  incur to  collect  this debt as
awarded by any court exercising jurisdiction under the Bankruptcy Code.

WAIVER:  I give up my rights to  require  you to do certain  things.  I will not
require you to:
(1)  demand payment of amounts due (presentment);
(2)  obtain official certification of nonpayment (protest); or
(3)  give notice that  amounts due have not been paid  (notice of  dishonor).  I
     waive any defenses I have based on suretyship or impairment of collateral.

OBLIGATIONS INDEPENDENT:  I understand that I must pay this note even if someone
else has also agreed to pay it (by, for example, signing this form or a separate
guarantee or endorsement). You may sue me alone, or anyone else who is obligated
on this note, or any number of us together,  to collect this note. You may do so
without  any  notice  that it has not been paid  (notice of  dishonor).  You may
without notice release any party to this agreement  without  releasing any other
party. If you give up any of your rights,  with or without  notice,  it will not
affect my duty to pay this note.  Any  extension  of new credit to any of us, or
renewal  of this note by all or less than all of us will not  release me from my
duty to pay it. (Of  course,  you are  entitled  to only one payment in full.) I
agree that you may at your option  extend this note or the debt  represented  by
this note,  or any portion of the note or debt,  from time to time without limit
or notice and for any term without  affecting  my  liability  for payment of the
note. I will not assign my obligation  under this  agreement  without your prior
written approval. 

CREDIT INFORMATION: I agree and authorize you to obtain credit
information  about me from time to time (for  example,  by  requesting  a credit
report) and to report to others your credit experience with me (such as a credit
reporting agency). I agree to provide you, upon request, any financial statement
or information you may deem necessary.  I warrant that the financial  statements
and information I provide to you are or will be accurate,  correct and complete.

NOTICE:  Unless  otherwise  required by law,  any notice to me shall be given by
delivering  it or by mailing it by first class mail  addressed to ome at my last
known address. My current address is on page 1. I agree to inform you in writing
of any change in my  address.  I will give any notice to you by mailing it first
class  to your  address  stated  on page 1 of this  agreement,  or to any  other
address that you have designated.
