Item 1. Business

Norton Drilling Services, Inc.

    Norton Drilling Services,  Inc., was originally incorporated on December 21,
1983 under the laws of the State of Delaware,  as Diagnostic  Sciences,  Inc. On
September 25, 1997 our stockholders  approved an amendment to our certificate of
incorporation changing our name to Norton Drilling Services, Inc.

    NDSI is a holding  company whose primary  assets consist of the voting stock
of each of the following subsidiary corporations:

    (i)   Norton  Drilling  Company,  a Delaware  corporation  ("Norton"  or the
          "Drilling  Segment"),  operates  sixteen oil and gas drilling rigs and
          provides  contract  drilling  services  to the oil  and  gas  industry
          primarily  in the Permian  Basin of west Texas and eastern New Mexico,
          the Green River Basin and the Overthrust  Belt in the Rocky  Mountains
          and in two states in Mexico.

    (ii)  Lobell  Corporation,  a  Delaware  corporation  ("Lobell"  or the "MRI
          Segment"),  which was, until August 18, 1994 when the operations  were
          discontinued,   engaged  primarily  in  providing  diagnostic  imaging
          services involving magnetic resonance imaging technology ("MRI"); and

    (iii) until July 22, 1996 when this company was sold, Sunny's Plants,  Inc.,
          a Florida  corporation  ("Sunny's  Plants" or the "Nursery  Segment"),
          which was, until April 6, 1995 when the operations were  discontinued,
          engaged primarily in the production and sale of indoor foliage plants.

    Our Board of Directors on August 18, 1994  discontinued  the MRI Segment due
to the Segment's recurring losses. On April 6, 1995, our Board also discontinued
the  operations  of the  Nursery  Segment  due to its  significant  losses.  The
consolidated  financial  statements  reflect a net  liability  of  approximately
$84,000 at November 30, 1998 and $105,000 at November 30, 1997 for the estimated
liabilities of the discontinued  segments.  See Item 1, Description of Business,
"MRI Segment" and "Nursery Segment" and also Note 3

                             Page 2 of 141 Pages

of Notes to Consolidated Financial Statements included as part of Item 8 of this
report.

    As NDSI is a  holding  company  it does  not  generate  operating  revenues.
Substantially  all of the funding for our expenses as well as for the payment of
the liabilities of the discontinued segments comes from Norton Drilling Company.

    Norton's agreements with one of its secured creditors prohibit virtually any
loans, dividends,  advances, guarantees of indebtedness or payments to us or our
subsidiaries.

    Norton  Drilling  Company - On October 1,  1991,  NDSI and its  wholly-owned
subsidiary  Norton  Drilling  Company,  completed  a merger  provided  for by an
Agreement  and Plan of Merger,  dated  September  13, 1991.  This  agreement was
between NDSI, Norton Drilling  Company,  a Texas corporation ("NDC (Texas)") and
each of Sherman H. Norton, Jr., S. Howard Norton, III, John W. Norton, J.P. Rose
and Barbara L. Norton (the "Norton Shareholders").  The Norton Shareholders were
holders of all of the capital  stock of NDC (Texas).  When the  transaction  was
completed, the Norton Shareholders surrendered all of the shares of stock of NDC
(Texas) and caused it to be merged into  Norton.  We paid to these  stockholders
1,032,000  shares of our common stock.  According to the agreement,  we expanded
our Board of Directors by three  positions and  appointed  the  following  three
persons  designated by the Norton  Shareholders to fill them: Sherman H. Norton,
Jr., S. Howard Norton,  III and John W. Norton.  We have  covenanted to nominate
and  recommend  for election or reelection to our Board of Directors up to three
people  designated by the Norton  Shareholders so long as they maintain  certain
percentage ownership of the 1,032,000 shares paid to them at the closing of this
transaction.  Also at the time the agreement was completed,  four members of NDC
(Texas)'s  management  entered  into five year  employment  and  non-competition
agreements.

    Lobell  Corporation - Our subsidiary  Lobell  Corporation  opened a magnetic
resonance imaging center in August 1986 in Huntington, New York.

    On August 18, 1994, our Board of Directors  discontinued the MRI Segment due
to its recurring losses. We have included $40,000 in our reserve for loss on the
discontinuance  of this segment as of November  30,  1998.  We believe that this
amount  will be  enough to settle  any costs we may incur in  disposing  of this
segment.  See Note 3 of Notes to Consolidated  Financial  Statements included as
part of Item 8 of this report.

    Sunny's  Plants,  Inc. - On February 28,  1991,  NDSI through a newly formed
subsidiary,  Sunny's Plants,  Inc.("Sunny's  Plants"),  purchased:(i)all  of the
assets and assumed  certain  obligations of Interior  Plant Supply  Partnership;
(ii)all of the outstanding shares of Sunshine Botanicals,  Inc.; (iii)all of the
outstanding  capital stock of Interior Plant Supply Inc.; and  (iv)certain  real
property from the sellers of the three above mentioned  entities according to an
Agreement and Plan of Reorganization.

    The total purchase price was $3,643,125 of which  $2,743,125 was paid by the
issuance of 462,000  shares of our common stock to each of the two  stockholders
of the above mentioned companies.

    On April 6, 1995, our Board of Directors  discontinued  the Nursery  Segment
due to its significant losses.


                             Page 3 of 141 Pages

<PAGE>



     As part of an agreement  entered  into in August,  1995 between the Nursery
Segment, NDSI, a third party purchaser and a secured creditor, the purchaser was
required to repay the  outstanding  balance of a mortgage  note in the  original
amount of $2,128,000 which was collateralized by the segment's real property. We
remain liable as guarantor for this  indebtedness  until the purchaser has fully
satisfied this obligation. In July 1998, the purchaser ceased making payments on
the obligation and filed for protection  under Chapter 7 of the U.S.  Bankruptcy
code.  The  unpaid  balance  of the  purchaser's  obligation  was  approximately
$1,784,000 at November 30, 1998. At November 30, 1998, the secured  creditor has
notified NDSI that they expect NDSI to make monthly  payments under the terms of
the mortgage note as well as any payments in arrears.  It is our intent to allow
the secured creditor to foreclose on the real property and it is our belief that
the secured  creditor will sell the property and that the proceeds from the sale
will satisfy amounts outstanding under the mortgage note.

    On July 22, 1996, we completed a Stock Purchase  Agreement with an unrelated
third party buyer.  According to this agreement,  the buyer purchased all of the
outstanding  shares  of  common  stock of  Sunny's  Plants,  Inc.  from us.  See
"Industry Segments;  Discontinued  Operations-Nursery  Segment" within this Item
and Note 3 of Notes to Consolidated  Financial  Statements included as a part of
Item 8 of this report for additional  discussion/disclosure  regarding financial
statement impact of the discontinuance of the Nursery Segment.

                              INDUSTRY SEGMENTS

    We are a  holding  company  with one  remaining  operating  segment,  Norton
Drilling Company. Norton owns and operates sixteen oil and gas drilling rigs and
provides  contract  drilling  services to the oil and gas industry.  The MRI and
Nursery  Segments  have been  discontinued  and all  activity  relative to those
segments is reflected as discontinued operations herein.

                            CONTINUING OPERATIONS

General

    NDSI,  headquartered in Lubbock,  Texas is a holding company and accordingly
does not generate operating revenues. We incur certain administrative costs that
are paid by charging  our  operating  subsidiary  management  fees.  We incurred
administrative  costs of approximately  $321,000 for the year ended November 30,
1998,   approximately  $167,000  for  the  year  ended  November  30,  1997  and
approximately  $228,000 for the year ended  November 30, 1996.  This resulted in
pre-tax  net loss of NDSI,  before  earnings  and  losses  of  subsidiaries,  of
approximately  $77,000 in 1998 and approximately $48,000 in 1996 and pre-tax net
income,  before earnings and losses of subsidiaries of approximately  $27,000 in
1997.

    Our  remaining   operating   subsidiary,   Norton  Drilling  Company,   also
headquartered in Lubbock,  Texas,  provides  contract drilling services to major
oil companies and  independent  oil and gas  producers  primarily in Texas,  New
Mexico,  the Rocky Mountains and,  through its  wholly-owned  subsidiary  Norton
Drilling Company Mexico, Inc., in Mexico. Norton Drilling provides its customers
with rigs and crews to operate the rigs.

    The primary assets of the oil and gas contract drilling segment consist
of sixteen land-based drilling rigs as of November 30, 1998. Norton's
drilling rig fleet ranges from small (7,500 ft. depth rating) self-propelled
drilling rigs to larger (22,000 ft. depth rating) diesel electric rigs. The

                             Page 4 of 141 Pages

<PAGE>



book value of the rigs was approximately $10,568,000 as of November 30, 1998 and
approximately  $9,543,000  as of November 30, 1997.  The rigs are equipped  with
drawworks or hoists, derricks or masts, engines, pumps to circulate the drilling
fluid, steel pits, blowout preventers,  drill pipe and drill collars and related
equipment.  The depth of the well and location  for  drilling are the  principal
factors  in  determining  the size and  type of rig used for a  particular  job.
Norton's  drilling  rigs are  utilized  for  both  exploration  and  development
drilling and can be used for either vertical or horizontal drilling.

    In order to continue to provide  quality and timely service to the Segment's
customers,  Norton  constantly  maintains two rigs in the Rocky Mountain region,
three rigs in Mexico and eight in its primary Texas and New Mexico areas.

    In  June,  1998,  Norton  incorporated  a  wholly-owned  subsidiary,  Norton
Drilling  Mexico,  Inc.,  ("Norton  Mexico")  through  which it  operates  three
drilling  rigs in the  states of Nuevo  Leon and  Tamaulipas,  in  Mexico.  This
company was  established  to operate inside  Mexico and to fulfill a contract to
drill 38 wells.

    For the year ended  November  30, 1998,  Norton,  including  Norton  Mexico,
reported income from operations before income taxes of approximately  $1,395,000
from  operating  revenues  of  approximately  $28,740,000.  For the  year  ended
November  30,  1997,  Norton had income  before  income  taxes of  approximately
$3,671,000  from operating  revenues of  approximately  $35,833,000.  Norton had
stockholder's  equity of  approximately  $8,888,000  as of November 30, 1998 and
$8,005,000 as of November 30, 1997. See "Managements' Discussion and Analysis of
Financial  Condition and Results of Operations"  and the  "Consolidated  Balance
Sheets, Statements of Operations, Stockholders' Equity, and Cash Flows" included
as  Items  7 and 8,  respectively,  of  this  report  for  additional  financial
information pertaining to the operating activities of this segment.

Business Strategy

    Norton  achieved  its  current  position  as a leading  provider of contract
drilling  services by providing  high  quality  services to its  customers  with
quality equipment.  Norton believes that the condition of the drilling rigs, the
reputation  of the  company  and the  quality  and  experience  of the  drilling
supervisors  and crews are of significant  importance to prospective  customers.
The Company has and will  continue to maintain its drilling rigs in good working
condition. In addition to normal repair and maintenance expenses,  Norton spends
significant  funds each year on an ongoing  program of improving  and  replacing
components  of its  drilling  rigs.  Norton also  strives to employ  experienced
drilling supervisors, toolpushers and crews for its rigs.

    Norton intends to continue to provide the highest quality contract  drilling
services with quality equipment and personnel.

Drilling Contracts

    Most of Norton's drilling contracts are with established  customers.  Norton
obtains most of its contracts  through a competitive  bidding process,  although
some are  obtained on a  negotiated  basis.  The operator of a well will request
bids under the terms it wishes (daywork, footage, turnkey), or occasionally will
solicit bids under various combinations of the above

                             Page 5 of 141 Pages

<PAGE>



mentioned  contract  types.  Generally,  the  contracts  are  entered  into  for
short-term  periods  and cover the  drilling of a single well with the terms and
rates varying  depending upon the nature and duration of the work, the equipment
and services  supplied and other matters.  The contracts  obligate Norton to pay
certain  operating   expenses,   including  wages  of  drilling   personnel  and
maintenance  expenses and to furnish incidental rig supplies and equipment.  The
contracts are subject to  termination  by the customer on short notice,  usually
upon payment of a fee. Norton generally indemnifies its customers against claims
by Norton's employees and claims arising from surface pollution caused by spills
of fuel,  lubricants  and other  solvents  within the  control  of  Norton.  See
subcaption  "Risks and Insurance" below in this Item. These customers  generally
indemnify  Norton  against  claims  arising  from other  surface and  subsurface
pollution, except claims arising from Norton's gross negligence.

    Under daywork  contracts,  Norton  provides the drilling rig, along with the
required personnel to the operator who supervises the drilling of the contracted
well.  Compensation to Norton is based on a negotiated rate per day that the rig
is utilized.  Daywork  contracts  generally  specify the type of equipment to be
used, the size of the hole and the depth of the proposed  well.  Under a daywork
contract, Norton generally does not incur any costs due to "inhole" losses (such
as  time  delays  for  various  reasons,   including  stuck  drill  strings  and
blow-outs).

    Footage  contracts usually require Norton to bear some of the drilling costs
in  addition  to  providing  the rig.  Under a footage  contract,  Norton  would
normally  determine  the manner of drilling  and type of  equipment  to be used,
subject to  certain  customer  specifications,  and also would bear the risk and
expense of mechanical malfunctions, equipment shortages and other delays arising
from drilling problems.  Compensation is based on a rate-per-foot-drilled  basis
to completion  of the well.  Prices of both footage and daywork  contracts  vary
depending  upon  various  factors  such as the  location,  depth,  duration  and
complexity  of the well to be drilled,  operating  conditions  and other factors
peculiar to each proposed well.

    Under turnkey  contracts,  Norton  contracts to drill a well to a contracted
depth under specified conditions and provides most of the equipment and services
required. Norton bears the risk of drilling the well to the contracted depth and
is usually compensated  substantially more than on wells drilled on a daywork or
footage  basis  because  Norton  assumes  significantly  greater  economic  risk
associated with drilling operations. If severe drilling problems are encountered
in drilling  wells under turnkey  contracts,  Norton could  sustain  substantial
losses.

    Norton's  management  believes  that  it  is  able  to  prevail  in  certain
situations where it is not the  lowest-priced  bidder because of the strength of
its reputation.  Nevertheless,  the bidding process is standard for the industry
and ensures that pricing is competitive.

    Contract drilling operations depend on the availability of drill pipe, bits,
fuel and qualified personnel,  some of which have been in short supply from time
to time.

    Norton's ability to drill wells for which it has contracts may be delayed by
inclement weather.  Sustained periods of inclement weather could have a material
adverse effect on Norton's revenues and cash flows.

Contract Drilling Activity

    The  following  table  sets forth  certain  information  regarding  Norton's
contract  drilling activity for each of the years in the three-year period ended
November 30, 1998.

  (1) Average for the periods stated.

  (2) Rig 1 had been stacked  since  January 18, 1992 and rig 2 had been stacked
      since May 9, 1991.  Rig 1 was not  available for service until January 25,
      1996 and rig 2 was not available for service until October 20, 1996 due to
      necessary  repairs and reworking on these rigs to get them in condition to
      operate again.  In January 1997 rig 1 was reworked and upgraded and became
      rig 17.  In May  1998 a new rig 1 was put  together  from  spare  parts we
      already  owned in addition to some new parts which we acquired  and became
      operational in June 1998.

  (3) Rig  utilization is based on a 365 day year for rigs available for service
      during the periods  indicated.  A rig is utilized  when it is operating or
      being moved, assembled or dismantled under contract.

  The contract drilling  industry responds to a number of market factors,  chief
among which is the level of exploration and production (E&P) expenditures of the
major oil  companies.  E&P spending  responds  primarily to the price of oil and
natural gas, but is also influenced by anticipated  changes in supply and demand
conditions,  tax  incentives  for tertiary  recovery,  and the  availability  of
alternative  fuels.  Domestic onshore drilling,  which is Norton's sole service,
also competes for E&P dollars with offshore and foreign drilling.

  During our fiscal  year ended  November  30,  1998 the price of oil has ranged
from  approximately  $11 to $19 per  barrel  whereas  in the  fiscal  year ended
November 30, 1997 it ranged from approximately $17 to $23 per barrel.  This drop
in price has significantly  decreased the cash flows to the producing  companies
for which Norton works. These companies in turn have decreased their budgets for
exploration and production expenditures. This decrease has caused a signficantly
reduced  demand for rigs to drill the various  prospects  that are profitable at
these oil prices. Therefore, there has been a decrease in rig utilization.  This
in turn has caused  Norton to have to reduce the price it charges for the use of
its rigs to levels much lower than in previous years.

      Norton's  primary  competition  comes from drilling  services  provided by
several large  integrated  oil field service  companies and by a number of large
and mostly smaller drilling companies.  Many firms have left the industry in the
past several years or have been acquired by larger drilling companies.

Customers

  Norton's  customers are generally  energy  companies  who  repeatedly  request
Norton's services. For the year ended November 30, 1998, Norton contract drilled
150  wells  for 30  customers.  This  compares  with 285  wells  drilled  for 44
customers  in the year ended  November 30,  1997,  and 304 wells  drilled for 33
customers in the year ended November 30, 1996.

   Over the past year, three customers accounted for a significant portion
of Norton's gross revenues. Those customers were Altura Energy Limited, Yates
Petroleum Corporation and a joint venture consisting of (i) Construcciones
Protexa, S.A. de C.V. (ii) Protexa Construcciones, S.A. de C.V. (iii) Avia de
Mexico, S.A. de C.V. and (iv) Avia Energy Development L.L.C. These three
customers accounted for approximately 51% of Norton's contract drilling
revenues during 1998.

  In addition to the three customers  mentioned above, Norton's customers in the
past twelve months have included, among others, Cimmaron Energy, Santa Fe Energy
and Texaco USA.

Drilling Equipment

    The following table sets forth information about the drilling rigs currently
owned by Norton:

                                                ===                ===

    All of the  drilling  rigs are  pledged as  collateral  on notes  payable of
Norton. See Note 6 of Notes to Consolidated  Financial  Statements included as a
part of Item 8 of this report.

    Norton owns 8 trucks with 9 trailers and two  forklifts.  This  equipment is
used to transport, rig up and rig down Norton's drilling rigs. Norton also hires
third parties on occasion to assist in the moving of rigs.

    Most  repair  and  overhaul  work on  Norton's  drilling  rigs  and  related
equipment is performed at Norton's yard  facilities  in Levelland,  Texas on the
drilling rigs located in Texas, New Mexico and Mexico.  Norton usually contracts
out this work on the drilling rigs located in the Rocky  Mountains area to third
parties.  Norton  believes that its drilling  rigs and related  equipment are in
good operating condition. In addition to repair and maintenance expenses, Norton
has historically  spent funds for its ongoing program of modifying and upgrading
its equipment.

Competition

    The  contract  drilling  industry  is highly  competitive.  No one  drilling
contractor  is  dominant.  Depressed  economic  conditions  in the  oil  and gas
industry has resulted in the supply of domestic drilling equipment substantially
exceeding  demand.  As a consequence,  there is intense  competition in securing
available  drilling  contracts,  resulting in drilling  equipment being idle for
long periods of time and generally unfavorable prices for contract drilling.

                             Page 8 of 141 Pages

<PAGE>



    Price has  generally  been the most  important  factor in securing  drilling
contracts.  Other  competitive  factors  include  the  availability  of drilling
equipment and  experienced  personnel at or near the time and place  required by
customers,  the reputation of the drilling  contractor in the drilling  industry
and its relationship with existing  customers.  Norton believes that it competes
favorably  with  respect to all of these  factors.  Competition  is usually on a
regional  basis,  although  drilling  rigs are  mobile and can be moved from one
region to another in response to increased  demand. An oversupply of rigs in any
region may result.  Demand for land drilling  equipment is also dependent on the
exploration and development programs of oil and gas companies, which are in turn
influenced  primarily by the financial  condition of such companies,  by general
economic  conditions,  by prices  of oil and gas,  and,  from  time to time,  by
political considerations and policies.

    It is impracticable to estimate the number of contract drilling  competitors
of  Norton,  some of which  have  substantially  greater  resources  and  longer
operating  histories  than  Norton.  In the  past  three  years  there  has been
considerable  consolidation  in  the  drilling  industry  with  larger  drilling
companies acquiring smaller ones. This has resulted in there being several large
drilling companies and fewer small ones. At this time this does not appear to be
a problem for Norton as it is able to provide its  customers  with the  personal
attention  they  desire,  which  is  sometimes  more  difficult  for the  larger
companies.  Also, in prior years, many drilling companies sought protection from
creditors under bankruptcy laws or undertook  business  combinations  with other
companies  as a  result  of the  downturn  in  the  domestic  contract  drilling
industry.  Although  these  two  factors  have  decreased  the  total  number of
competitors,  management  of  Norton  believes  that  competition  for  drilling
contracts will continue to be intense for the foreseeable future.

Government Regulation and Environmental

    The domestic  drilling of oil and gas wells is subject to numerous state and
federal laws, rules and regulations.  State statutory provisions relating to oil
and  natural  gas  generally  include  requirements  as to well  spacing,  waste
prevention, production limitations, pollution prevention and clean-up, obtaining
drilling  permits  and  similar  matters.   Within  the  state  of  Texas  these
regulations are principally enforced by the Texas Railroad  Commission.  To date
Norton has not been required to expend significant resources in order to satisfy
applicable  environmental  laws and regulations.  Norton does not anticipate any
material  capital  expenditures  for  environmental  control  facilities  or for
compliance with environmental  rules and regulations in the foreseeable  future.
However,  compliance  costs under  existing  laws or under any new  requirements
could become  material,  and Norton could incur  liabilities for  noncompliance.
Norton  has not been  fined  or  incurred  liabilities  for  pollution  or other
environmental  damage in  connection  with its  operations  and is not currently
aware of any environmental hazards which would materially affect its operations.

    The contract  drilling industry is dependent on demand for services from the
oil and gas exploration industry and,  accordingly,  is affected by changing tax
laws and other laws relating to the energy business generally. Norton's business
is affected generally by political  developments and by federal,  state, foreign
and local laws and  regulations  which relate to the oil and gas  industry.  The
adoption  of laws  and  regulations  affecting  the oil  and  gas  industry  for
economic,  environmental  and other policy reasons could increase costs relating
to drilling and production, which could have an

                             Page 9 of 141 Pages

<PAGE>



adverse effect on the Company's operations. State and federal environmental laws
and  regulations  which currently apply to Norton could become more stringent in
the future.  The Federal Resource  Conservation  and Recovery Act ("RCRA"),  and
comparable  state statutes govern the disposal of "hazardous  wastes."  Although
RCRA  excludes  certain  classes  of  exploration  and  production  wastes  from
regulation, such exemptions by Congress under RCRA may be deleted or modified in
the future.  There are many other Acts and  statues  that govern the oil and gas
drilling industry,  however,  due to the complexity and changing nature of these
regulations,  we are  unable  to  determine  all of those  that may  impact  our
operations.

Risks and Insurance

    Norton's operations are subject to the many hazards inherent in the drilling
business,  including blow-outs,  cratering, fires, and explosions. These hazards
could cause personal injury or death,  suspend drilling  operations or seriously
damage or destroy the  equipment  involved  and,  in  addition to  environmental
damage,  could cause substantial damage to producing  formations and surrounding
areas. Damage to the environment,  including property  contamination in the form
of either soil or ground water  contamination,  could also result from  Norton's
operations,   particularly  through  oil  spillage,  gas  leaks  and  extensive,
uncontrolled  fires.  In addition,  Norton could become subject to liability for
reservoir damage. The occurrence of a significant event,  including pollution or
environmental  damage, could materially affect Norton's operations and financial
condition. As a protection against operating hazards, Norton maintains insurance
coverage  considered  by  Norton to be  adequate,  including  all-risk  physical
damage,   employer's  liability,   commercial  general  liability  and  workers'
compensation  insurance.  Norton  currently has $1,000,000 of general  liability
insurance per occurrence  with an aggregate of $2,000,000  and excess  liability
and umbrella  coverages of up to $10,000,000  per occurrence  with a $10,000,000
aggregate.  Norton's  customers  generally  require  Norton  to  have  at  least
$1,000,000  of third  party  liability  coverage.  See  Note 14 of the  Notes to
Consolidated  Financial Statements included as part of Item 8 of this report for
further disclosures regarding the aforementioned contingencies.

    Norton Drilling believes that it is adequately  insured for public liability
and property  damage to others with  respect to its  operations.  However,  such
insurance  may not be  sufficient to protect  Norton  against  liability for all
consequences  of  well  disasters,  extensive  fire  damage  or  damage  to  the
environment.  Norton also carries  insurance to cover physical damage to or loss
of its  drilling  rigs.  However,  it does not carry  insurance  against loss of
earnings  resulting from such damage or loss.  Norton's  lenders have a security
interest  in the  drilling  rigs and are named as loss  payees  on the  physical
damage  insurance on such rigs. In view of difficulties  that may be encountered
in renewing such insurance at reasonable  rates,  no assurance can be given that
Norton  will be able to  maintain  the  type  and  amount  of  coverage  that it
considers  adequate at reasonable  rates or that any particular type of coverage
will be available.

    Norton provides worker's compensation insurance for its Texas and New Mexico
resident  employees  through a  fully-insured  plan which was effective  July 1,
1997. This policy has a deductible of $1,000 per occurrence.

    From November 1, 1992 to June 30, 1997, Norton carried worker's compensation
insurance for its Texas  resident  employees,  with a deductible of $100,000 per
occurrence.  Starting November 1, 1993, Norton purchased  reinsurance to provide
coverage for the $100,000 deductible. The reinsurance

                             Page 10 of 141 Pages

<PAGE>



policy  provided  for a  deductible  of $5,000.  From August 1, 1995 to June 30,
1997, the New Mexico resident employees were covered under this same policy.

    Workers'  compensation  insurance coverage for Norton's employees in all the
other states in which it has  employees is provided for by  fully-insured  plans
administered by the various states.

                           DISCONTINUED OPERATIONS
    MRI Segment

    The MRI  Segment,  prior  to its  discontinuation  in 1994,  rented  its MRI
machine to a professional corporation,  whose shareholders were physicians.  The
MRI Segment was operational from July, 1986 to March, 1995.

    On August 18, 1994, our Board of Directors  discontinued the MRI Segment due
to its recurring losses. We have included $40,000 in our reserve for loss on the
discontinuance  of this segment as of November  30,  1998.  We believe that this
amount  will be  enough to settle  any costs we may incur in  disposing  of this
segment.  However,  the  actual  amounts  paid  could  be less  that  estimated,
resulting in a possible gain. We estimate that the gain could be in the range of
$5,000 to  $40,000.  See Note 3 of Notes to  Consolidated  Financial  Statements
included as part of Item 8 of this report.

    Nursery Segment

    On February 28, 1991,  Sunny's  Plants,  a  wholly-owned  subsidiary of ours
until  July  22,  1996,  acquired  (i) all of the  assets  and  assumed  certain
obligations of Interior Plant Supply  Partnership,  (ii) all of the  outstanding
shares of Sunshine  Botanicals,  Inc. (iii) all of the outstanding capital stock
of Interior  Plant  Supply,  Inc.,  and (iv)  certain real  property  located in
Florida.

    Prior to its  discontinuance in 1995 as discussed below, the Nursery Segment
was primarily in planting,  growing and preparing  plants for  distribution  and
sale in the wholesale and retail market.

    On April 6, 1995, our Board of Directors  discontinued  the Nursery  Segment
due to its significant losses.

     As part of an agreement  entered  into in August,  1995 between the Nursery
Segment, NDSI, a third party purchaser and a secured creditor, the purchaser was
required to repay the  outstanding  balance of a mortgage  note in the  original
amount of $2,128,000 which was collateralized by the segment's real property. We
remain liable as guarantor for this  indebtedness  until the purchaser has fully
satisfied this obligation. In July 1998, the purchaser ceased making payments on
the obligation and filed for protection  under Chapter 7 of the U.S.  Bankruptcy
code.  The  unpaid  balance  of the  purchaser's  obligation  was  approximately
$1,784,000 at November 30, 1998. At November 30, 1998, the secured  creditor has
notified NDSI that they expect NDSI to make monthly  payments under the terms of
the mortgage note as well as any payments in arrears.  It is our intent to allow
the secured creditor to foreclose on the real property and it is our belief that
the secured  creditor will sell the property and that the proceeds from the sale
will  satisfy  amounts  outstanding  under  the  mortgage  note.  See  "Industry
Segments;  Discontinued  Operations-Nursery Segment" within this Item and Note 3
of Notes to Consolidated  Financial  Statements  included as a part of Item 8 of
this report for additional  discussion/disclosure  regarding financial statement
impact of the discontinuance of the Nursery Segment.

                             Page 11 of 141 Pages

<PAGE>



    We believe  that the  estimate of  remaining  future costs to be incurred in
disposing  of this Segment of  approximately  $44,000 is adequate to provide for
future  liabilities.  If the amount actually paid to settle these liabilities is
less than the amount  included in the current  reserve,  then we could  record a
gain.  Our best estimate of the potential gain is between  approximately  $5,000
and  $30,000.  See Note 3 of the  Notes  to  Consolidated  Financial  Statements
included as a part of Item 8 of this report.

    On July 22, 1996, we completed a Stock Purchase  Agreement with an unrelated
third party buyer.  According to this agreement,  the buyer purchased all of the
outstanding  shares  of  common  stock of  Sunny's  Plants,  Inc.  from us.  See
"Industry Segments;  Discontinued  Operations-Nursery  Segment" within this Item
and Note 3 of Notes to Consolidated  Financial  Statements included as a part of
Item 8 of this report for additional  discussion/disclosure  regarding financial
statement impact of the discontinuance of the Nursery Segment.

    There can be no certainty  that any or all of the possible  gains in the MRI
Segment or the Nursery Segment will ever be realized. Their final realization is
dependent  on a number  of  factors.  These may  include,  among  other  things,
extinguishment of existing  liabilities under Federal  bankruptcy laws. While we
believe  that  filing  of  bankruptcy  for the  segments  or  settlement  of the
liabilities will relieve the segments of their  obligations and result in gains,
there can be no  certainty of such due to  potential  rights of creditors  under
applicable   state  laws  and/or  the   intricacies  of  meeting  the  technical
requirements  of Federal  bankruptcy  laws.  Because of the problems which could
arise under either course of action, the outcome is subject to many issues which
are  outside  our  control.  Therefore,  the amount of  liabilities  that may be
extinguished  and the possible  resulting gain, if any, that would be recognized
is uncertain at this time.

    The net liabilities of the discontinued  segments are approximately  $84,000
at November 30, 1998 and $105,000 at November 30, 1997.

Employees

    Norton had a total of 209  full-time  employees (13 as office
personnel  and 196 as field  personnel)  as of November 30, 1998.  The number of
field  personnel  will fluctuate  depending on the demand for Norton's  contract
drilling services. Norton considers its employee relations to be satisfactory.

Item 3. Legal Proceedings

     On January 6, 1998, a judgment was rendered in favor of Norton  against one
of its  customers  for  non-payment  on account.  The  judgment  awarded  Norton
approximately  $464,000 plus  pre-judgment  interest of  approximately  $84,000.
Interest on the judgment will continue to accrue at the rate of 18% until paid.

     In February 1995, a default  judgment in the amount of $79,999 was obtained
in the Local District  Court,  Huntington,  New York,  against Lobell and us, as
guarantor,  by the landlord of the premises  which were then occupied by Lobell.
The judgment was secured based on the  non-payment  of monies  alleged to be due
and owing  under a  stipulation  executed  by the  parties on  November 1, 1994.
Following such judgment,  the landlord evicted Lobell and obtained a judgment on
February 15, 1995 for the non-payment of rent in the amount of $33,408.

     We are from time to time subject to routine  litigation  incidental  to our
business.  Other than as set forth above, as of November 30, 1998, there were no
pending material proceedings to which we or our management was a party. See Note
14 of Notes to Consolidated Financial Statements included as a part of Item 8 of
this report.

            CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR"
      PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

      We are including the following  cautionary  statement to take advantage of
the "safe harbor" provisions of the Private Securities  Litigation Reform Act of
1995 for any  forward-looking  statement  made by,  or on  behalf  of NDSI.  The
factors  identified in this cautionary  statement are important factors (but not
necessarily  all of the important  factors)  that could cause actual  results to
differ materially from those expressed in any forward-looking statement made by,
or on behalf  of,  NDSI.  Where any such  forward-looking  statement  includes a
statement of the assumptions or bases underlying such forward-looking statement,
we caution that, while we believe such assumptions or bases to be reasonable and
make them in good faith,  assumed  facts or bases almost always vary from actual
results,  and the differences  between assumed facts or bases and actual results
can be material, depending upon the circumstances. Where, in any forward-looking
statement,  we express an expectation or belief as to the future  results,  such
expectation  or  belief  is  expressed  in good  faith  and  believed  to have a
reasonable  basis,  but  there  can  be  no  assurance  that  the  statement  of
expectation or belief will result,  or be achieved or accomplished.  Taking into
account the  foregoing,  the following are  identified as important risk factors
that could cause actual results to differ materially from those expressed in any
forward-looking statement made by, or on behalf of, NDSI:

      VOLATILITY OF OIL AND NATURAL GAS PRICES. Norton's revenue,  profitability
and future rate of growth are substantially dependent upon prevailing prices for
oil and natural gas. In recent years, oil and natural gas prices and, therefore,
the  level  of  drilling,  exploration  and  development,  have  been  extremely
volatile.  Prices are  affected by market  supply and demand  factors as well as
actions  of state and local  agencies,  the U.S.  and  foreign  governments  and
international  cartels.  All of  these  factors  are  beyond  our  control.  Any
significant  or  extended  decline in oil and/or  natural gas prices will have a
material  adverse  effect on our financial  condition and  operations  and could
impair  access to  sources of  capital.  The sharp  decline in oil prices  which
started in the latter part of 1997 has adversely impacted our operations. If oil
prices remain at current levels or continue to decline, or if natural gas prices
decline, our operations could be further adversely affected.

      MARKET  CONDITIONS FOR CONTRACT DRILLING  SERVICES.  The contract drilling
business has experienced decreased demand for drilling services due to lower oil
prices. A particularly  sharp decline in demand for contract  drilling  services
occurred  in 1986 and  again  in the  current  year  because  of the  world-wide
collapse  in oil  prices.  Since  this time and  except  during  the  occasional
upturns,  there  have been  substantially  more  drilling  rigs  available  than
necessary  to meet  demand in most  operating  and  geographic  segments  of the
domestic  drilling  industry.  As  a  result,   drilling  contractors  have  had
difficulty  sustaining  profit margins.  In addition to the adverse effects that
future declines in demand could have on us, ongoing  movement or reactivation of
onshore  drilling  rigs or new  construction  of drilling  rigs could  adversely
affect rig  utilization  rates and pricing even in an  environment of higher oil
and natural gas prices and increased drilling

                             Page 14 of 141 Pages

<PAGE>



activity.  We cannot  predict  either  the future  level of demand for  contract
drilling services or future conditions in the contract drilling industry.

      SHORTAGE OF DRILL PIPE IN THE CONTRACT DRILLING  INDUSTRY.  There has been
shortage of drill pipe in the contract drilling industry in the U.S. in the past
few years.  As a result of this shortage the price of drill pipe has  increased.
This  shortage,  however,  fluctuates  with the  demand  for  contract  drilling
services.

      COMPETITION.  Norton encounters intense competition in its operations from
other drilling  contractors.  The competitive  environment for contract drilling
services involves such factors as drilling rates,  availability and condition of
drilling rigs and equipment, reputation and customer relations. Many of Norton's
competitors  have  substantially  greater  financial  and other  resources  than
Norton.

      OPERATING HAZARDS AND UNINSURED RISKS.  Contract  drilling  activities are
subject to a number of risks and hazards  which could  cause  serious  injury or
death to persons,  suspension  of  drilling  operations  and  serious  damage to
equipment  or property of others and, in addition to the  environmental  damage,
could cause substantial  damage to producing  formations and surrounding  areas.
Damages  to  the  environment   could  result  from  the  Norton's   operations,
particularly  through  oil  spills,  gas  leaks,  discharges  of toxic  gases or
extensive  uncontrolled  fires.  In addition,  Norton  could  become  subject to
liability  for  reservoir  damages.  The  occurrence  of  a  significant  event,
including  pollution or environmental  damage,  could materially affect Norton's
operations  and  financial  condition.  Although  Norton  believes  that  it  is
adequately  insured  against normal and  foreseeable  risks in its operations in
accordance  with  industry  standards,  such  insurance  may not be  adequate to
protect  Norton  against  liability  from all  consequences  of well  disasters,
extensive  fire damage or damage to the  environment.  No assurance can be given
that Norton will be able to maintain  adequate  insurance in the future at rates
it  considers  reasonable  or that  any  particular  types of  coverage  will be
available.  Furthermore,  a portion of Norton's  contract  drilling is done on a
turnkey basis, which involves substantial economic risks.

      ENVIRONMENTAL  AND  OTHER  GOVERNMENTAL   REGULATION   MATTERS.   Norton's
operations  are subject to numerous  domestic laws and  regulations  that relate
directly or indirectly  to the drilling of oil and natural gas wells,  including
laws  and   regulations   controlling   the  discharge  of  materials  into  the
environment, requiring removal and cleanup under certain circumstances otherwise
relating to the protection of the environment.  Laws and regulations  protecting
the environment  have generally become more stringent in recent years and may in
certain  circumstances  impose  strict  liability,  rendering  Norton liable for
environmental  damage  without  regard to  negligence or fault on their part. To
date, Norton has not been required to expend  significant  resources in order to
comply with  applicable  environmental  laws and regulations nor has it incurred
any fines or  penalties  for  noncompliance.  However,  compliance  costs  under
existing  legal  requirements  and  under  any  new  requirements  could  become
material,  and Norton  could incur  liability  in the future for  noncompliance.
Additional matters subject to governmental  regulation include discharge permits
for drilling operations and performance bonds concerning operations.

PART II

Item 5. Market For Registrant's Common Equity and Related Stockholder Matters

     NDSI's  common  stock,  $.01 par value per share,  was traded on the NASDAQ
National  Market  under the symbol  "NORT"  until  February  2, 1999.  Effective
February 2, 1999, our common stock began trading on the NASDAQ  National  Market
System under the symbol  "NORCD" and  management  was  notified  that the common
stock would continue to trade under that symbol for twenty trading days at which
time the trading symbol will revert to either "NORTC" or "NORT". The table below
sets forth the high and low selling  prices for our common stock for the periods
indicated on the NASDAQ National Market.

Fiscal 1997                                          High          Low

First quarter                                      $ 3.75        $1.95
Second quarter                                       3.15         2.10

Fiscal 1998

First quarter                                      $15.00        $4.85
Second quarter                                       9.20         4.85
Third quarter                                        6.10         2.35

     On January  29, 1999 at our annual  stockholders  meeting,  a  one-for-five
reverse  split of our  common  stock was  approved.  Par value and the number of
authorized  shares  remained at $0.01 per share and  100,000,000,  respectively.
Earnings  per  share,  stock  prices  and all other  disclosures  regarding  our
stockholders'   equity,   common  stock  and  related  stock  option  plans  and
outstanding  warrants  for all  periods  presented  reflect  the  effects of the
reverse split.

     On February 24, 1999 the number of holders of record of our common stock
was approximately 270.
                             
     We have  not  paid  dividends  on our  common  stock in the past and do not
expect to pay any dividends on it in the foreseeable  future.  Instead we intend
to retain the earnings to support the operations and  anticipated  growth of our
business.  Any future cash dividends  would depend on future  earnings,  capital
requirements,  our financial  condition and other factors deemed relevant by the
Board of Directors.  In addition, the terms of existing bank indebtedness of our
operating  subsidiary prohibits payment of dividends to us without prior written
consent  of  their  lenders.  See  Note 6 of  Notes  to  Consolidated  Financial
Statements included as a part of Item 8 of this report for discussion  regarding
certain restrictive covenants included in our debt agreements.

     The  following   subparagraph  sets  forth  information  concerning  equity
securities  issued by us during 1997 but not registered under the Securities Act
of 1933, as amended (the "Act"):

     (a) On February 23, 1997,  79,214 shares of our common stock were issued to
         certain employees of Norton in partial satisfaction of amounts

                             Page 16 of 141 Pages

<PAGE>



         due them on employment  contracts.  We believe that the issuance of the
         shares was exempt from the  registration  requirements  of Section 5 of
         the Act by virtue of Section  4(2),  as a  transaction  not involving a
         public offering.  More specifically,  we believe the officers were able
         to fend  for  themselves  with  access  to  information  upon  which an
         investment decision can be made.

Liquidity and Capital Resources

    As of November 30, 1998, we had working capital of approximately $98,000 and
cash and cash equivalents of approximately  $172,000. This compares to a working
capital  deficiency of  approximately  $511,000 and cash and cash equivalents of
approximately $277,000 at November 30, 1997.

    For the year ended November 30, 1998, our operations provided  approximately
$2,182,000 in cash flows and our  financing  activities  provided  approximately
$1,478,000.  The provision of funds is largely attributable to our net income as
adjusted  for  depreciation  for the year and by  additional  borrowings  in the
Drilling Segment.  For the year ended November 30, 1997, our operations provided
approximately  $2,435,000  in cash flows and our financing  activities  provided
approximately  $387,000.  The provision of funds was largely attributable to our
increased net income for the year and somewhat by  additional  borrowings in the
Drilling  Segment.  See  "Part  I.  Item  1.  Description  of  Business-Industry
Segments;  Discontinued  Operations-MRI  Segment  and  Nursery  Segment" of this
report and Note 3 of Notes to Consolidated Financial Statements included as part
of Item 8 of this report.

     Significant  expenditures  which we  incurred  primarily  consisted  of the
Drilling Segment's continual acquisition of replacement drilling equipment, such
as drill collars, drill pipe, engines and transportation equipment to adequately
maintain the operating  status of the drilling fleet.  These  expenditures  were
approximately  $4,053,000 for the year ended  November 30, 1998,  $3,757,000 for
the year ended  November 30, 1997 and $1,878,000 for the year ended November 30,
1996. The Drilling Segment anticipates  minimal capital  expenditures for fiscal
1999 to be funded from existing bank credit lines and cash flow from operations.
See Note 6 of Notes to Consolidated  Financial  Statements included as a part of
Item 8 of this report. Due to numerous uncertainties regarding the availability,
price and delivery of certain drilling equipment,  Norton's anticipated level of
capital  expenditures  may  fluctuate  commensurate  with the  volatility of the
industry.

     We  believe  that cash  flows  from  operations  and  borrowings  should be
sufficient to fund continuing operations and adequately service our debt for the
next twelve months. The risks associated with the oil and gas industry,  such as
the volatility of oil and gas prices,  could  adversely  affect our  operations.
Considering the current adverse  conditions in the industry in which the company
operates  (e.g.,  the  significant  decrease  in  worldwide  oil  prices and the
resulting downturn in the demand for contract driling services),  management has
addressed the covenant  provision  within its loan  agreements  with the lending
bank. The bank has reduced the net worth requirement to $6,000,000.  See Notes 1
and 3 of Notes to Consolidated  Financial  Statements included as part of Item 8
of this report.

Results of Continuing Operations

    Comparison of the years ended November 30, 1998 and 1997

    For the year  ended  November  30,  1998  contract  drilling  revenues  were
approximately $28,721,000 as compared to $35,833,000 for the year ended November
30, 1997, a decrease of $7,112,000 or 19.8%.  Average rig  utilization was 66.4%
in 1998 compared to 92.4% in 1997. The decrease in drilling  revenues was due to
a decrease in rig  utilization  and a decrease  in rates  charged for the use of
these drilling rigs.

    Direct job and rig costs for 1997 were approximately $22,391,000 or 78.0% of
contract drilling revenues as compared to approximately  $28,504,000 or 79.5% of
contract  drilling  revenues  in  1997.  The  decrease  in costs  was  primarily
attributable  to the decrease in the number of rigs which Norton was  operating.
Direct rig and jobs costs decreased slightly as a percentage

                            Page 19 of 141 Pages

<PAGE>



of revenues because of the rig rates that Norton was getting for its rigs
located in Mexico.

    General  and   administrative   expenses  for  the  drilling   segment  were
approximately  $1,527,000  in 1998 as compared to  approximately  $1,159,000  in
1997.  The  increase  was due to  start  up costs  associated  with  the  Mexico
operations,  increases in travel and telephone costs  associated with the Mexico
operations,  the write off to bad debt expense of accrued interest on a judgment
that was deemed uncollectable and the hiring of additional office personnel.

    Interest   expense  was   approximately   $484,000   in  1998   compared  to
approximately $561,000 in 1997 representing a decrease of approximately $77,000.
The decrease in interest  expense was due to a reduction in the interest rate on
Norton's debt and the conversion of subordinated debt in November 1997 to common
stock of NDSI.

    In  1998  income  before  income  taxes  and  discontinued   operations  was
approximately   $1,318,000  as  compared  to  income  before  income  taxes  and
discontinued  operations of  approximately  $3,698,000 in 1997.  The decrease in
income was due to the decrease in drilling revenues and increases in general and
administrative costs and depreciation.

    Comparison of the years ended November 30, 1997 and 1996

    For the year  ended  November  30,  1997  contract  drilling  revenues  were
approximately $35,833,000 as compared to $26,677,000 for the year ended November
30, 1996, an increase of $9,156,000 or 34.3%.  Average rig utilization was 92.4%
in 1997 compared to 82.1% in 1996. The increase in drilling  revenues was due to
an increase in rig  utilization  and an increase in rates charged for the use of
these drilling rigs.

    Direct job and rig costs for 1997 were approximately $28,504,000 or 79.5% of
contract drilling revenues as compared to approximately  $23,496,000 or 88.1% of
contract  drilling  revenues  in  1996.  The  increase  in costs  was  primarily
attributable  to the increase in the number of rigs which Norton was  operating.
Direct rig and jobs costs  decreased  as a  percentage  of revenues  because the
rates Norton  charged for the use of its drilling rigs  increased  more than its
costs associated with those rigs.

    General  and   administrative   expenses  for  the  drilling   segment  were
approximately  $1,159,000  in 1997 as compared to  approximately  $1,243,000  in
1996. Included in general and administrative expenses for 1997 was a decrease in
the allowance for doubtful  accounts  receivable  in the  approximate  amount of
$59,000. Conversely, in 1996 there was an increase in the allowance for doubtful
accounts receivable of approximately $187,000.

    Interest   expense  was   approximately   $561,000   in  1997   compared  to
approximately  $394,000  in 1996  representing  an  increase  of  $167,000.  The
increase  was due to an  increase in the amount of debt  outstanding  during the
year.

    In  1997  income  before  income  taxes  and  discontinued   operations  was
approximately   $3,698,000  as  compared  to  income  before  income  taxes  and
discontinued  operations  of  approximately  $538,000 in 1996.  This increase in
income was due to the increase in rig revenues, a higher gross profit margin and
an increase in rig utilization.

Income Taxes

    For the year ended November 30, 1996, no income tax expense was recorded due
to the  utilization of net operating loss ("NOL")  carryforwards  which had been
generated in prior years. At November 30, 1996, we had approximately  $2,216,000
of  remaining  NOL  carryforwards  which  could be  applied to future tax years.
During the year ended  November  30,  1997,  all of these  remaining  NOL's were
utilized  and charges to  operations  of  approximately  $1,283,000  for federal
income taxes and  approximately  $206,000 for state income taxes were  recorded.
During the year ended  November 30, 1998 charges to operations of  approximately
$477,000  for federal  income taxes and  approximately  $13,000 for state income
taxes were recorded.  See Note 9 of Notes to Consolidated  Financial  Statements
included as part of Item 8 of this report.

    The Drilling Segment's revenue and profitability are substantially dependent
upon prevailing  prices for oil and gas.  Historically,  oil and gas prices have
been extremely volatile. Prices are affected by market supply and demand factors
as well as actions of state and local  agencies,  the United  States and foreign
governments and  international  cartels.  All of these are beyond the control of
the Drilling  Segment.  Any  significant  or extended  decline in oil and/or gas
prices  could have a material  adverse  effect on our  financial  condition  and
results of operations.  The price of oil rose to a six-year high in January 1997
and fell to a ten-year  low in March 1998 and  continue to be  depressed  in the
current period.  Should oil prices remain at these levels or decline further, or
if natural  gas  prices  decline,  our  operations  could be  further  adversely
affected.

Impact of Inflation

    While  subject to  inflation,  our  business  was not  impacted by inflation
during the past three  fiscal years in any  material  respect.  We do no believe
that inflation will have a material impact on our business in the near future.

Year 2000

    During 1997 we began evaluating computer systems to identify the those which
could be affected  by the Year 2000 issue.  The "Year 2000 issue" is whether our
computer  systems will properly  recognize date sensitive  information  when the
year  changes  to 2000 or "00".  Programs  that were not  designed  to  properly
recognize such dates could generate erroneous data or cause a system to fail. We
reviewed our computer  systems and  identified  those systems that were not year
2000 compliant.

    Those  systems that were not year 2000  compliant  were replaced in November
1998.  The cost to replace the  non-compliant  systems  were not material to our
financial position and results of operations.

    Our ability to conduct our business  efficiently and  productively  requires
that our customers and vendors be year 2000 compliant.  We have not assessed the
readiness  and  effectiveness  of our  customers and vendors in regards to their
compliance  with  year  2000  problems.  However,  we plan  to  make  inquiries,
solicitations  and surveys of these customers and vendors in the current year on
an on-going basis to determine our level of

                            Page 21 of 141 Pages

<PAGE>



vulnerability  from  our  customers  and  vendors.   We  do  not  anticipate  an
interruption  of our operations  relative to Year 2000 concerns of our customers
and  vendors.  Therefore,  we do not  deem  it  necessary  to  formally  adopt a
contingency plan.

    The  failure  to  correct a  material  year  2000  problem  could  result in
interruptions or failures of our normal business activities or operations.  Such
failures  could  materially  and  adversely  affect our  results of  operations,
liquidity and financial condition. Due to the uncertaintity inherent in the year
2000 problem,  resulting in part from the uncertainty of the year 2000 readiness
of our  customers  and vendors,  we are unable to determine at this time whether
the  consequences  of year  2000  failures  will have a  material  impact on our
results of operations,  liquidity or financial  condition.  We believe that with
the completion of upgrading our computer systems and the review of the status of
our customers and vendors year 2000  readiness,  the  possibility of significant
interruptions of normal operations should be reduced.

Results of Discontinued Operations

    MRI Segment

      During fiscal 1994, our Board of Directors  chose to  discontinue  the MRI
Segment due to its recurring  losses.  In fiscal 1995, all of the assets of this
segment were garnished, confiscated or abandoned.

      The  results of  operations  of this  segment  was $-0- for the year ended
November 30, 1998 as compared to income  before  income  taxes of  approximately
$25,000  for the year ended  November  30,  1997.  The  change in the  segment's
results of operations was  attributable to our revision of the initial  estimate
made in 1994 to reserve for the ultimate  loss to be incurred in the disposal of
the segment.  This revision  resulted in a credit to operations of approximately
$25,000  for the year  ended  November  30,  1997  and  $-0- for the year  ended
November 30, 1998.

    In fiscal 1997,  the results of  operations of the MRI Segment was income of
approximately $25,000 as compared to income of approximately  $396,000 in fiscal
1996.  The change in the  segment's  results of operations  is  attributable  to
management's  revision of its initial  estimate  made in 1994 to reserve for the
ultimate  loss to be incurred  in the  disposal of the  segment.  This  revision
resulted in a credit to operations of  approximately  $25,000 for the year ended
November 30, 1997 and $396,000  for the year ended  November 30, 1996.  See also
PART  1,  Item  1-Description  of  Business;   "Industry   Segments-Discontinued
Operations" for additional discussion.

    Nursery Segment

    As of November 30, 1994,  our Board of Directors  chose to  discontinue  the
Nursery Segment due to its recurring  losses.  In fiscal 1995, all of the assets
of this segment were seized through foreclosure of the segment's indebtedness.

      The results of operations of this segment in fiscal 1998 was $-0- compared
to income before income taxes of approximately  $228,000 in 1997. In fiscal 1998
there were no  adjustments  to  previously  recorded  reserves  relative to this
discontinued  segment whereas in fiscal year 1997 we had a credit to the initial
estimate made to reserve for the ultimate loss to be incurred in the disposal of
the segment of approximately $228,000.

                            Page 22 of 141 Pages

<PAGE>



    The  results of  operations  of this  segment  in fiscal  1997 was income of
approximately $228,000.  This compares to income of approximately  $2,497,000 in
fiscal 1996.  The decrease in the segment's  results of operations  for the year
ended November 30, 1997 compared to 1996 is attributable  to two events.  First,
in July 1996 the Nursery  Segment was sold.  This sale  relieved  the segment of
liabilities to its unsecured creditors.  Second, a transaction occurred in which
we were indemnified for certain  liabilities of the Nursery segment and in which
a third party paid a secured creditor all amounts due on another liability.

Recent Accounting Standards

      The Financial  Accounting  Standards  Boards ("FASB") issued SFAS No. 130,
"Reporting  Comprehensive  Income" which establishes standards for reporting and
the presentation of comprehensive income and its components (revenues, expenses,
gains and losses) in a full set of general-purpose  financial  statements.  SFAS
No.  130  requires  that all items  that are  required  to be  recognized  under
accounting  standards as  components  of  comprehensive  income be reported in a
financial  statement  that is  displayed  with  the  same  prominence  as  other
financial  statements.  SFAS No. 130 requires  that an  enterprise  (1) classify
items of other comprehensive income by their nature in a financial statement (2)
display the accumulated  balance of other  comprehensive  income separately from
retained  earnings and  additional  paid-in  capital in the equity  section of a
statement of  financial  position.  SFAS No. 130 is  effective  for fiscal years
beginning  after  December 15, 1997 and will be adopted by us during the quarter
ending February 28, 1999 in our 1999 fiscal year. We do not anticipate that this
statement  will  have  a  significant  effect  on  our  consolidated   financial
statements.

    The FASB issued SFAS No. 131,  "Disclosures  About Segments of an Enterprise
and  Related  Information".  SFAS No. 131  establishes  revised  guidelines  for
determining an entity's  operating  segments and the type and level of financial
information  to be  disclosed.  SFAS  No.  131 is  effective  for  fiscal  years
beginning  after  December 15, 1997 and will be adopted by us during the quarter
ending February 28, 1999 in our 1999 fiscal year. We do not anticipate that this
statement  will  have  a  significant  effect  on  our  consolidated   financial
statements.

    The FASB issued SFAS No. 132,  "Employers'  Disclosures  about  Pensions and
Other Postretirement Benefits" in February 1998. SFAS No. 132 revises employers'
disclosures  about pension and other  postretirement  benefit plans. It does not
change the measurement  recognition of those plans.  This statement is effective
for fiscal years  beginning after December 15, 1997 and will be adopted by us in
our fiscal year ending  November 30, 1999.  The adoption of this new standard is
not expected to have a material impact to us.

    The FASB issued SFAS No. 133,  "Accounting  for Derivative  Instruments  and
Hedging  Activities"  in June 1998.  SFAS No.  133  establishes  accounting  and
reporting  standards for derivative  instruments,  including certain  derivative
instruments  embedded  in other  contracts,  and for  hedging  activities.  This
statement is effective for all fiscal  quarters of fiscal years  beginning after
June 15,  1999 and  will be  effective  for us at the  beginning  of our  fiscal
quarter  ending  February 29, 2000.  The provisions of this new standard are not
expected to have a material impact to us.

    The above long term loans carry variable interest rates.

    Our operations  described in detail in Item 1 "Business"  consists primarily
of providing contract drilling services to oil and gas producers.  We attempt to
mitigate our  commodity  price risk by entering into short term  contracts.  Our
future cash flow from drilling operations are exposed to significant  volatility
as commodity prices changes. Our future cash flows could vary significantly from
historical cash flows.

Item 13. Certain Relationships and Related Transactions

       On May 19,  1993 a  former  officer  of  Norton  advanced  $90,000  and a
director/former  officer  of ours  advanced  $410,000  to  Norton in the form of
unsecured  demand  notes.  These notes bore interest  equal to Norton's  primary
lending  institution's  prime rate. The notes were  convertible  into our common
stock at $2.20 per share for a total 227,273  shares.  The Conversion  Price was
determined  by our Board of  Directors  at its  meeting  on May 19,  1993,  at a
premium  over the average of the bid and ask price of the shares of common stock
at the close of  business  on May 18,  1993.  On  November  13,  1997  these two
individuals  exercised  their  option to convert  the notes into our stock.  See
Notes 6 and 12 of Notes to Consolidated  Financial Statements included as a part
of Item 8 of this report.

      Two of our directors,  a corporation owned by one of our directors,  and a
former officer of Norton have ownership interests in an entity from which Norton
purchased drilling rig machinery at a cost of $168,155 in 1997.

      In the year  ended  November  30,  1995,  the  three  individuals  and the
corporation mentioned above, along with the Drilling Segment,  participated in a
joint venture in three wells. The joint venture contracted with Norton to drill,
equip, and operate the three wells and incurred costs of  approximately  $34,000
in the year ending November 30, 1998, $58,000 in the

                            Page 30 of 141 Pages

<PAGE>



year ending November 30, 1997 and $83,000 in the year ending November 30, 1996.

      In April, 1996, Norton sold substantially all of its interest in the joint
venture to a  corporation  in which the two directors of NDSI,  the  corporation
owned by a director of NDSI and the former officer of Norton,  are stockholders.
The sales price of the interest sold was $200,000 and Norton  realized a gain on
the sale of the interest of approximately $117,000.

      On June 6, 1996, we purchased  216,619 shares of our common stock at $0.40
per share from a corporation owned by two former  directors/officers of NDSI and
their spouses as part of a stock purchase and settlement agreement.

      In February 1997, the Board of Directors  directed the officers of NDSI to
issue  79,214  shares of  common  stock to four  individuals,  three of whom are
directors  of  NDSI,  as  payment  for  unpaid  salaries  that  were  due  these
individuals  according to employment agreements Norton had with them. The number
of shares issued was based upon a valuation provided by an independent valuation
consultant.  These share have not been  registered  under the  Securities Act of
1933, as amended.

                   REPORT OF INDEPENDENT ACCOUNTANTS


Board of Directors and Stockholders
Norton Drilling Services, Inc.
Lubbock, Texas


We have audited the accompanying  consolidated balance sheets of Norton Drilling
Services,  Inc.  and  Subsidiaries  as of November  30,  1998 and 1997,  and the
related consolidated  statements of operations,  stockholders'  equity, and cash
flows for each of the three years in the period ended  November 30, 1998.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the consolidated  financial position of Norton Drilling
Services  Inc.  and  Subsidiaries  as of  November  30,  1998 and 1997,  and the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period ended  November 30, 1998 in conformity  with generally
accepted accounting principles.

As  discussed in Note 2 to the  financial  statements,  the Company  changed its
method of accounting for earnings per share in 1998.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1. HISTORICAL OVERVIEW

     Norton Drilling Services,  Inc.,  ("NDSI") was incorporated on December 21,
1983 under the laws of the State of Delaware.

     Norton Drilling Company  ("Norton" or "NDC") a Delaware  corporation is our
only remaining operating segment and currently operates sixteen (16) oil and gas
drilling  rigs  and  provides  contract  drilling  services  to the  oil and gas
industry  primarily in the Permian Basin of west Texas and eastern New Mexico as
well as in the Green River Basin and the Overthrust  Belt in the Rocky Mountains
and in two states in Mexico.

     Prior  to the  incorporation  of  Norton  and the  acquisition  of NDC,  we
operated two other subsidiaries,  Sunny's Plants, Inc.("Sunny's" or the "Nursery
Segment") and Lobell Corporation ("Lobell" or the "MRI Segment").

     Sunny's,  which was acquired on February 28, 1991, was engaged primarily in
planting,  growing and preparing  interior  foliage plants for  distribution and
sale.  Lobell was engaged  primarily in providing  diagnostic  imaging  services
involving MRI technology.

     NDSI, in particular  the Nursery and MRI  Segments,  sustained  substantial
losses from operations in the past. On August 18, 1994 we  discontinued  the MRI
segment,  and on April 6, 1995 we discontinued  the Nursery segment due to these
significant losses.

     On July 22,  1996,  we effected the closing of a Stock  Purchase  Agreement
between  a third  party  purchaser  ("Buyer")  and us.  In  accordance  with the
agreement the Buyer purchased all of the  outstanding  shares of common stock of
Sunny's Plants, Inc., in consideration of certain releases and the payment by us
to the Buyer of $10,000.

     During fiscal 1996 and 1997, a  substantial  amount of  liabilities  of the
discontinued  segments were reduced  either through the  aforementioned  sale of
Sunny's or through favorable negotiations with the respective creditors of those
segments.

     As NDSI is a  holding  company  it does not  generate  operating  revenues.
Substantially  all of the funding for our expenses as well as for the payment of
the liabilities of the discontinued segments comes from Norton Drilling Company.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Continued)





2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of consolidation

     The consolidated  financial statements include the accounts of NDSI and our
wholly-owned  subsidiary,  Norton as continuing  operations  and the accounts of
Lobell Corporation,  as discontinued  operations.  All significant  intercompany
accounts and transactions have been eliminated.

Management estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

Revenue and cost recognition

     We follow  the  percentage-of-completion  method for  recognizing  contract
drilling  revenues.   Under  this  method  all  drilling  revenues,   costs  and
appropriate  portions of indirect  costs,  related to the work in progress,  are
recognized as contract drilling  services are performed.  Contract costs include
all direct  material and labor costs and any indirect  costs related to contract
performance.  General  and  administrative  costs  are  charged  to  expense  as
incurred.  Provision for losses on incomplete  contracts are recognized when the
loss can be determined.

Property and equipment

     (a)   Property  and   equipment   -Depreciation   is  computed   using  the
straight-line method over the estimated useful lives as follows:
                                             Lives (years)
                                             -------------
           Drilling rigs and equipment             2-8
           Automotive equipment                     5
           Office furniture                        3-10
           Buildings                                20
           Other                                    3



     (b) Maintenance and repairs-Maintenance and repairs expenses are charged to
operations  as  incurred.  Renewals  and  betterments  which  extend the life or
improve  properties are  capitalized.  Labor costs incurred in  constructing  or
improving assets are capitalized.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

     (c)  Retirements-Upon  disposition or retirement of property and equipment,
the cost and related accumulated  depreciation are removed from the accounts and
the gain or loss thereon, if any, is credited or charged to income.

Income taxes

     Income  taxes  are  provided  based  on  earnings  reported  for  financial
statement  purposes.  The  provision  for income taxes  differs from the amounts
currently payable because of temporary differences in the recognition of certain
income and expense items for financial reporting and tax reporting purposes.

     Deferred tax liabilities  and assets are determined  based on the temporary
differences  between the financial statement and tax basis of certain assets and
liabilities  using enacted rates in effect for the year in which the differences
are expected to reverse.

     We file a  consolidated  Federal  income tax  return.  Under a tax  sharing
agreement,  the  subsidiaries  are charged an amount equal to the Federal income
taxes they would pay if a separate  return were  filed.  If a  subsidiary  has a
taxable  loss, it receives  credit for its pro-rata  share of the tax savings to
the consolidated  group.  The subsidiaries  also provide deferred Federal income
taxes on a  separate  return  basis on  temporary  differences  between  tax and
financial  reporting  to the extent that taxes which would  otherwise  have been
payable are reduced.

Stock based compensation

     We grant stock options under stock-based  incentive  compensation  plans to
our employees and directors.  Compensation costs in connection with the granting
of stock options to employees and directors is measured  under the provisions of
Accounting  Principles  Board ("APB")  Opinion No. 25 which allows  compensation
costs to be measured based on an intrinsic value method.  In 1995, the Financial
Accounting  Standards  Board ("FASB") issued  Statement of Financial  Accounting
Standards  ("SFAS") No.123 "Accounting for Stock-Based  Compensation"  which, if
fully  adopted  by  us,  would  change  the  method  we  apply  in   recognizing
compensation costs relative to options granted under our plans.  Adoption of the
cost recognition  provisions of SFAS No. 123 is optional and we have decided not
to elect those provisions.  However,  pro-forma disclosures as if we had adopted
the costs recognition  provisions of SFAS No. 123 are required and are presented
in Note 13.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Statement of cash flows

     For purposes of reporting  cash flows,  cash and cash  equivalents  include
cash on hand,  cash on deposit and  unrestricted  certificates  of deposit  with
original maturities of less than 90 days.

Goodwill

     The excess of cost of the acquisition of the drilling segment over the fair
market  value of the net assets of the  segment at the date of  acquisition  has
been included in the consolidated  financial statements as goodwill and is being
amortized on the straight-line method over 20 years.

Impairment of long-lived assets

     Impairment of long-lived assets such as property and equipment and goodwill
is evaluated  upon the  occurrence  of events which would call into question the
recoverability  of the carrying amount of those assets.  Impairment,  if any, is
measured  as the  difference  between  the  carrying  value of the asset and the
undiscounted sum of the expected future net cash flows.

Income per common share

     We adopted the  provision of Statement  of Financial  Accounting  Standards
("SFAS") No. 128  "Earnings  per Share"  during the quarter  ended  February 28,
1998. This standard amends  Accounting  Principles  Board ("APB") Opinion No. 15
"Earnings per Share" and requires the presentation of basic and diluted earnings
per share  versus  primary and fully  diluted  earnings per share which had been
required by APB Opinion No. 15.  Earnings per share for the years ended November
30, 1997 and 1996 have been  restated to conform with the  requirements  of SFAS
No. 128. The adoption of this new standard did not have a material  effect to us
for the years ended November 30, 1998, 1997 and 1996.

     Basic  earnings  per share  ("EPS") has been  computed  using the  weighted
average number of common shares  outstanding during the years ended November 30,
1998, 1997 and 1996.

     Diluted  EPS has been  computed  based on the  weighted  average  number of
common shares  outstanding  during years ended November 30, 1998,  1997 and 1996
and on the net  additional  number of shares  which would be  issuable  upon the
exercise  of stock  options,  assuming  that we used the  proceeds  received  to
purchase  additional  shares at market  value as well as the  additional  shares
issuable  relative to  convertible  debt which was  outstanding  at November 30,
1996. Additional shares relative to stock options and convertible debt have been
excluded   from  the   determination   of  diluted  EPS  when  their  effect  is
anti-dilutive.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Stock split

     On January 29, 1999, we effected a one-for-five reverse split of our common
stock. All information  regarding earnings per share, weighted average number of
common shares  outstanding,  stock options and warrants issued and exercised and
all other related  disclosures  herein reflect the effects of such reverse split
for all periods presented.

Environmental costs

     NDSI and Norton expense on a current basis, recurring costs associated with
managing hazardous  substances in ongoing  operations.  We also accrue for costs
associated with the remediation of environmental  contamination  when it becomes
probable  that a liability  has been  incurred and the amount can be  reasonably
estimated.  Management is aware of no such  liability  that has been incurred at
November 30, 1998.

Recent accounting standards

     The  Financial  Accounting  Standards  Board  ("FASB")  issued  Statment of
Financial  Accounting  Standards  ("SFAS")  No.  130,  "Reporting  Comprehensive
Income"  which  establishes  standards for  reporting  and the  presentation  of
comprehensive income and its components (revenues,  expenses,  gains and losses)
in a full set of  general-purpose  financial  statements.  SFAS No. 130 requires
that all items that are required to be recognized under accounting  standards as
components of comprehensive  income be reported in a financial statement that is
displayed with the same prominence as other financial  statements.  SFAS No. 130
requires that an enterprise (1) classify items of other comprehensive  income by
their nature in a financial  statement  (2) display the  accumulated  balance of
other  comprehensive  income  separately  from retained  earnings and additional
paid-in capital in the equity section of a statement of financial position. SFAS
No. 130 is effective for fiscal years beginning after December 15, 1997 and will
be adopted by us during the quarter ending  February 28, 1999 in our 1999 fiscal
year.

     The FASB issued SFAS No. 131,  "Disclosures About Segments of an Enterprise
and  Related  Information".  SFAS No. 131  establishes  revised  guidelines  for
determining an entity's  operating  segments and the type and level of financial
information  to be  disclosed.  SFAS  No.  131 is  effective  for  fiscal  years
beginning  after  December 15, 1997 and will be adopted by us during the quarter
ending February 28, 1999 in our 1999 fiscal year

     The FASB issued SFAS No. 132,  "Employers'  Disclosures  about Pensions and
Other Postretirement Benefits" in February 1998. SFAS No. 132 revises employers'
disclosures  about pension and other  postretirement  benefit plans. It does not
change the measurement  recognition of those plans.  This statement is effective
for fiscal years  beginning after December 15, 1997 and will be adopted by us in
our fiscal year ending  November 30, 1999.  The adoption of this new standard is
not expected to have a material impact to us.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

     The FASB issued SFAS No. 133,  "Accounting  for Derivative  Instruments and
Hedging  Activities"  in June 1998.  SFAS No.  133  establishes  accounting  and
reporting  standards for derivative  instruments,  including certain  derivative
instruments  embedded  in other  contracts,  and for  hedging  activities.  This
statement is effective for all fiscal  quarters of fiscal years  beginning after
June 15,  1999 and  will be  effective  for us at the  beginning  of our  fiscal
quarter  ending  February 29, 2000.  The provisions of this new standard are not
expected to have a material impact to us.

Reclassifications

     Certain  reclassifications have been made to the 1996 and 1997 consolidated
financial  statements  in order for them to conform with the 1998  presentation.
The  reclassifications  had no effect on net income or stockholders'  equity for
those years.

3. DISCONTINUED OPERATIONS

     On  August  18,  1994,  we  discontinued  the  MRI  Segment  due to  losses
experienced by the segment. We estimated future costs and expenses to dispose of
the segment to be  $750,000.  In fiscal  1996,  we revised our initial  estimate
which resulted in a credit of  approximately  $396,000 to the provision for loss
on discontinued  segments.  Our initial estimate was further revised during 1997
which resulted in a credit to the provision for loss on discontinued segments of
approximately $25,000. The remaining liabilities of the segment primarily relate
to claims filed by the  segment's  former  landlord for past due rent. We are of
the opinion that if negotiations  with the former landlord are not successful in
settling these  obligations,  we will cause the segment to seek  protection from
the landlord under bankruptcy proceedings.  It is possible that final settlement
and  dissolution  of the segment will result in the payment of less than amounts
which  are  currently  recorded  as  liabilities.  This  could  result in a gain
realized in the  reversing of these  recorded  liabilities.  Our estimate of the
potential gain is between approximately $5,000 and $40,000.

     Effective  November 30, 1994, we  discontinued  the Nursery  Segment due to
significant operating losses incurred by that segment.

     As part of an agreement  entered  into in August,  1995 between the Nursery
Segment, NDSI, a third party purchaser and a secured creditor, the purchaser was
required to repay the  outstanding  balance of a mortgage  note in the  original
amount of $2,128,000 which was collateralized by the segment's real property. We
remain liable as guarantor for this  indebtedness  until the purchaser has fully
satisfied this obligation. In July 1998, the purchaser ceased making payments on
the obligation and filed for protection  under Chapter 7 of the U.S.  Bankruptcy
code.  The  unpaid  balance  of the  purchaser's  obligation  was  approximately
$1,784,000 at November 30, 1998. As of November 30, 1998,  the secured  creditor
has notified NDSI that they expect NDSI to make monthly payments under the terms
of the mortgage note as well as any payments in arrears

3. DISCONTINUED OPERATIONS (Continued)

     It is our intent to allow the  secured  creditor to  foreclose  on the real
property and it is our belief that the secured  creditor  will sell the property
and that the proceeds from the sale will satisfy amounts  outstanding  under the
mortgage note.

     On July 22,  1996,  we effected the closing of a Stock  Purchase  Agreement
between  a third  party  purchaser  ("Buyer")  and us.  In  accordance  with the
agreement,  the Buyer purchased all of the outstanding shares of common stock of
Sunny's Plants,  Inc.,  from us, in  consideration  of certain  releases and the
payment by us to the Buyer of $10,000.

     On August 29, 1997 we settled a claim against the Nursery Segment and us as
guarantor.  This  claim was  included  in the net  liabilities  of  discontinued
operations at November 30, 1996 in the amount of $365,074. In settlement of this
claim we paid $275,000 to the creditor and have  recorded a receivable  from the
purchaser of the Nursery  Segment in the amount of $138,000 in  connection  with
indemnification  due us by the  purchaser  under  an  indemnification  agreement
entered into in connection with the sale of the assets of the Nursery Segment.

     The net liabilities of the discontinued operations at November 30, 1998 and
1997 are as follows:

                                                   1998          1997

     In addition to the  specific  collateralization  discussed  above,  certain
indebtedness  was  further  collateralized  by a  corporate  guaranty of NDSI at
November 30, 1998.

     The weighted average interest rate on short term indebtedness during fiscal
1998 and 1997 was 10.5% and 10.9%, respectively.

     The aforementioned obligations contain a number of representations,
warranties and covenants, the breach of which, at the election of the
respective lender would accelerate the maturity date of the obligations. The
most restrictive covenants include:

        -Maintenance by Norton of a net worth of at least $8,000,000,
        -Maintenance by Norton of a maximum leverage ratio of 2.75:1 and a
         minimum current maturity coverage ratio of 1.25:1;
        -Norton shall not involve itself in significant capital acquisitions,
         nor shall it sell, transfer, impair or otherwise encumber underlying
         collateral without prior written consent of the lender; and
        -Norton shall not pay  dividends or make loans to others  without  prior
         written consent of the lender.

        Norton was in violation of the covenant pertaining to capital
acquisitions at November 30, 1998 for  which the bank has  agreed to waive their
right to accelerate the maturity of the respective notes through December 1,
1999.
 
        A bank  has  issued a letter  of  credit  to  Norton's  former  Workers'
Compensation Insurance carrier on behalf of Norton in the amount of $166,375. No
advances had been made against this letter of credit as of November 30, 1998.

        Aggregate amounts of annual  maturities of notes payable  outstanding at
November 30, 1998 are as follows:

7. EMPLOYEE BENEFIT PLANS

Retirement plans

     Norton has a defined  contribution  profit  sharing  plan which  covers all
qualified  employees.  Contributions  to  the  profit  sharing  plan  are at the
discretion  of  Norton's  Board of  Directors.  In November  1997,  the board of
directors  approved a contribution to the profit sharing plan of $50,000,  which
was paid on December 30, 1997.  This amount was included in accounts  payable at
November 30, 1997. No  contributions  were made by Norton during the years ended
November 30, 1996 and 1998.

Health care costs

     Norton   maintains  a   self-insurance   program  for  health  care  costs.
Self-insurance   retention   is  $30,000  per   employee  and  an  aggregate  of
approximately  $280,000 per year. Liabilities in excess of these amounts are the
responsibility  of the  co-insurance  carrier.  Included in accrued  expenses at

self-insurance program in the amounts of $38,110 and $86,272, respectively.

10. MAJOR CUSTOMERS

     Norton  had  three  customers  who  accounted  for   approximately  51%  of
consolidated operating revenues for the year ended November 30, 1998. Norton had
two  customers  each  year  who  accounted  for  approximately  28%  and  42% of
consolidated  operating revenues for the years ended November 30, 1997 and 1996,
respectively.

11. RELATED PARTY TRANSACTIONS

      On May  19,  1993 a  former  officer  of  Norton  advanced  $90,000  and a
director/former  officer  of NDSI  advanced  $410,000  to  Norton in the form of
unsecured demand notes.  These notes required interest equal to Norton's primary
lending  institution's  prime rate. The notes were  convertible  into our common
stock at $2.20 per share for a total 227,273  shares.  The Conversion  Price was
determined  by our Board of  Directors  at its  meeting  on May 19,  1993,  at a
premium  over the average of the bid and ask price of the shares of common stock
at the close of business on May 18, 1993.  Interest charged to operations on the
notes  payable  was  $40,241  and  $41,651  in 1997 and 1996,  respectively.  On
November 13, 1997,  the two  individuals  exercised  their option to convert the
notes into our common stock.

     Two of our directors,  a corporation  owned by one of our directors,  and a
former officer of Norton have ownership interests in an entity from which Norton
purchased drilling rig machinery at a cost of $168,155 in 1997.

     In the  year  ended  November  30,  1995,  the  three  individuals  and the
corporation mentioned above, along with the Drilling Segment,  participated in a
joint venture in three wells. The joint venture contracted with Norton to drill,
equip, and operate the three wells and incurred costs of  approximately  $34,000
in the year ending  November 30, 1998,  $58,000 in the year ending  November 30,
1997 and $83,000 in the year ending November 30, 1996.

11. RELATED PARTY TRANSACTIONS (Continued)

     In April,  1996, Norton sold substantially all of its interest in the joint
venture to a  corporation  in which the two directors of NDSI,  the  corporation
owned by a director of NDSI and the former officer of Norton,  are stockholders.
The sales price of the interest sold was $200,000 and Norton  realized a gain on
the sale of the interest of approximately $117,000.

     On June 6, 1996, we purchased  216,619  shares of our common stock at $0.40
per share as part of a stock  purchase and  settlement  agreement for a total of
$86,648.  As a part of the agreement,  we also  delivered  $30,000 to be used to
assist in the  resolution  of certain  pending  tax claims  against  the Nursery
Segment and two former directors. In return, we were indemnified with respect to
certain liabilities of the Nursery Segment.

     In February 1997,  the Board of Directors  directed the officers of NDSI to
issue  79,214  shares of  common  stock to four  individuals,  three of whom are
directors  of  NDSI,  as  payment  for  unpaid  salaries  that  were  due  these
individuals  according to employment agreements Norton had with them. The number
of shares issued was based upon a valuation provided by an independent valuation
consultant.  These share have not been  registered  under the  Securities Act of
1933, as amended.


12. COMMON STOCK

Stock issuance

     On May  19,  1993  a  former  officer  of  Norton  advanced  $90,000  and a
director/former  officer  of NDSI  advanced  $410,000  to  Norton in the form of
unsecured demand notes.  These notes required interest equal to Norton's primary
lending  institution's  prime rate. The notes were  convertible  into our common
stock at $2.20 per share for a total  227,273  shares of our  common  stock.  On
November 13, 1997,  the two  individuals  exercised  their option to convert the
notes into our common stock.

     Through November 30, 1996, four employees of Norton, three of which are our
directors,  had not been paid a total of  $266,350  to which they were  entitled
under  their  employment  agreements  with  us.  At a  meeting  of our  Board of
Directors on February 23, 1997,  the officers of NDSI were  directed to take all
action  necessary to issue to these four employees 79,214 shares of common stock
worth  $166,349 in partial  satisfaction  of the unpaid  amounts.  The number of
shares  that was issued was based upon a  valuation  of a  recognized  valuation
expert  opining as to the fair market  value of the price of the common stock to
be received.

     During the year ended  November 30,  1998,  options for 8,900 shares of our
common stock were  exercised.  During the year ended November 30, 1997,  options
for 83,200  shares of our common stock were  exercised.  All these  options were
part of those issued under our 1989 Stock Option Plan.  The option prices ranged
from  $0.625 to $2.80 per share.  As part of our 1989  Stock  Option  Plan,  the
person who holds the option  can pay the option  price by giving us back  common
stock which has a fair market value on the date of exercise  equal to the option
price.  During fiscal year 1998,  we had 1,849 shares  returned to us as payment
for the 8,900  options that were  exercised  and during fiscal year 1997, we had
24,471  shares  returned  to us as  payment  for the  83,200  options  that were
exercised.

13. STOCK OPTIONS AND WARRANTS

1989 stock option plan

     In June 1989, the stockholders approved our 1989 stock option plan (the "89
Plan").  The Plan provides for the granting of a total of 100,000  qualified and
non-qualified options to employees, officers, directors and consultants of NDSI.

     During the year ended  November 30, 1998,  options to purchase 8,900 shares
of our stock were  exercised  at a price $2.03 per share.  During the year ended
November 30, 1997, options to purchase 83,200 shares of our stock were exercised
at prices ranging from $0.625 to $2.80 per share.

     At November 30, 1998,  remaining options outstanding under the 89 Plan were
options granted on May 21, 1997 to two  non-employee  directors to acquire 2,000
shares  each  under  the plan at $3.15 per  share  ($12,600)  which was the fair
market value at that date.

     All  options  under the 89 Plan expire five years from the date the options
were granted.

1997 Stock Option Plan

     On September 25,1997, our stockholders  approved the 1997 Stock Option Plan
(the "97 Plan").  The 97 Plan allows for the  awarding of stock  options,  stock
appreciation  rights  or  restricted  stock.  These  awards  can be  made to our
officers,  employees,   directors  or  consultants  at  the  discretion  of  the
compensation  committee of our board of directors.  The maximum number of shares
of our common stock  reserved for the grant of awards under this plan is 230,000
shares.

     On  February 6, 1998,  our Board of  Directors  issued  options to purchase
152,440  shares of our common  stock to  certain  employees  of Norton  Drilling
Company  at an  exercise  price of $7.50 per share in  accordance  with our 1997
Stock Option Plan.

     On April 14, 1998, our Board of Directors issued options to purchase 12,000
shares of our common  stock to our three  non-employee  directors at an exercise
price of $6.00 per share in accordance with our 1997 Stock Option Plan.

     On September 11, 1998,  our Board of Directors  issued  options to purchase
2,000 shares of our common stock to an employee of Norton Drilling Company at an
exercise price of $3.30 per share in accordance with our 1997 Stock Option Plan.

     The fair value of each stock option and/or warrant granted was estimated on
the  date of  grant  using  the  Black-Scholes  option  pricing  model  with the
following  weighted  average  assumptions  for  grants  during  the years  ended
November 30, 1998 and 1997:

Leases

     Norton  entered  into a five year  noncancellable  operating  lease for its
general  office space in Lubbock,  Texas in May 1994.  In September  1997 Norton
executed an addendum to this lease for additional  space. The addendum period is
for 20 months and  expires  at the same time as the  original  lease  agreement.
Norton  also  leases  storage  space in Texas and  Wyoming  and office  space in
Midland,  Texas and in Rio Grande  City,  Texas on month to month  leases.  Rent
expense  charged to  operations  under  operating  leases  amounted  to $58,249,
$48,584 and $57,140 in 1998, 1997 and 1996, respectively.

     Minimum future lease payments under operating leases are as follows:

Letters of credit

     As of November 30, 1998, Norton is contingently liable under an irrevocable
letter of credit in the amount of $166,375.

Employment contracts

     On December 1, 1995, NDSI, through its subsidiary, Norton Drilling
Company, entered into five-year employment contracts with each of Sherman H.
Norton, Jr., S. Howard Norton, III, John W. Norton and Johnie P. Rose. The
contracts provide for annual salaries of $104,500 to each of these employees
with no provision for annual bonuses.

     On March 1, 1997, NDSI,  through its subsidiary,  Norton Drilling  Company,
entered into a new five-year  employment  contract  with Sherman H. Norton,  Jr,
which replaced the above-mentioned  agreement for him. The new contract provides
for an annual  salary of $153,500.  The  provisions of this new contract are the
same as the prior contract for Mr. Norton except for the amount of salary.

     On December 1, 1995, Norton entered into a three-year  employment agreement
with one of it's employees which provides for a salary of $78,000 per year. This
agreement was renewed and extended for an additional  three years on December 1,
1998 under the same provisions and for the same amount as before.

Litigation

     The  Company is  involved  in various  routine  litigation  incident to its
business.  In the  Company's  opinion,  none of these  proceedings  will  have a
material adverse effect on the Company in management's opinion.

Contingencies

     Norton's  operations  are  subject  to the  many  hazards  inherent  in the
drilling business, including blow-outs,  cratering, fires, and explosions. These
hazards could cause personal  injury or death,  suspend  drilling  operations or
seriously  damage  or  destroy  the  equipment  involved  and,  in  addition  to
environmental damage, could cause substantial damage to producing formations and
surrounding areas. Damage to the environment,  including property  contamination
in the form of either soil or ground water contamination, could also result from
Norton's operations, particularly through oil spillage, gas leaks and extensive,
uncontrolled  fires.  In addition,  Norton could become subject to liability for
reservoir damage. The occurrence of a significant event,  including pollution or
environmental  damage, could materially affect Norton's operations and financial
condition. As a protection against operating hazards, Norton maintains insurance
coverage considered by Norton to be adequate, including all-risk physical

damage,   employer's  liability,   commercial  general  liability  and  workers'
compensation  insurance.  Norton  currently has $1,000,000 of general  liability
insurance per occurrence  with an aggregate of $2,000,000  and excess  liability
and umbrella  coverages of up to $10,000,000  per occurrence  with a $10,000,000
aggregate.  Norton's  customers  generally  require  Norton  to  have  at  least
$1,000,000 of third party liability coverage.

Year 2000

     During 1997 we began  evaluating  computer  systems to  identify  the those
which could be affected by the Year 2000 issue. The "Year 2000 issue" is whether
our computer systems will properly recognize date sensitive information when the
year  changes  to 2000 or "00".  Programs  that were not  designed  to  properly
recognize such dates could generate erroneous data or cause a system to fail. We
reviewed  our  computer  systems  and  identified  those that were not year 2000
compliant.

     Those systems that were not year 2000  compliant  were replaced in November
1998.  The cost to replace the  non-compliant  systems  were not material to our
financial position and results of operations.

     Our ability to conduct our business  efficiently and productively  requires
that our customers and vendors be year 2000 compliant.  We have not assessed the
readiness  and  effectiveness  of our  customers and vendors in regards to thier
compliance  with  year  2000  problems.  However,  we plan  to  make  inquiries,
solicitations  and surveys of these customers and vendors in the current year on
an on-going basis to determine our level of vulnerability from our customers and
vendors. We do not anticipate an interruption of our operations relative to Year
2000  concerns  of our  customers  and  vendors.  Therefore,  we do not  deem it
necessary to formally adopt a contingency plan.

     The  failure  to  correct a  material  year 2000  problem  could  result in
interruptions or failures of our normal business activities or operations.  Such
failures  could  materially  and  adversely  affect our  results of  operations,
liquidity and financial condition. Due to the uncertaintity inherent in the year
2000 problem,  resulting in part from the uncertainty of the year 2000 readiness
of our  customers  and vendors,  we are unable to determine at this time whether
the  consequences  of year  2000  failures  will have a  material  impact on our
results of operations,  liquidity or financial  condition.  We believe that with
the completion of upgrading our computer systems and the review of the status of
our customers and vendors year 2000  readiness,  the  possibility of significant
interruptions of normal operations should be reduced.

15. CONCENTRATIONS OF CREDIT RISK

     Financial  instruments  which  potentially  subject us to concentrations of
credit risk consist primarily of demand deposits, temporary cash investments and
trade receivables.

     We believe that we place our demand deposits and temporary cash investments
with high  credit  quality  financial  institutions.  Our  demand  deposits  and
temporary cash  investments  consisted of the following at November 30, 1998 and
1997:

                                                    1998           1997  
                                                 ---------      ---------
      Deposit in FDIC insured institutions
         under $100,000                           $201,547      $ 102,889
      Deposit in FDIC insured institutions
         over $100,000                             456,483        325,252
                                                  --------       --------
                                                   658,030        428,141
      Less outstanding checks and other
         reconciling items                        (485,709)      (151,044)
                                                  --------       --------
      Cash and cash equivalents                   $172,321       $277,097
                                                  ========       ========

     Concentrations  of  credit  risk  with  respect  to trade  receivables  are
primarily  focused  on  contract  drilling  receivables.  The  concentration  is
somewhat mitigated by the diversification of customers for which Norton provides
drilling services. As of November 30, 1998, we had contract drilling receivables
of approximately  $3,297,000  related to drilling  contracts in Mexico (see Note
17). While we believe that the receivables  will be collected from the customer,
we have credit insurance with respect to those  receivables and intend to file a
claim if the receivables  become past due. No significant losses from individual
contracts  were  experienced  during the years ended November 30, 1998 and 1997.
Included  in general and  administrative  expense is a charge to  operations  of
approximately  $227,000  which  was  mainly  attributable  to the  write  off of
interest accrued on a judgment for the year ended November 30, 1998 and a credit
to the provision for doubtful receivables of approximately  $59,000 for the year
ended November 30,1997.

     Norton  had  three  customers  who  accounted  for   approximately  51%  of
consolidated operating revenues for the year ended November 30, 1998. Norton had
two  customers  each  year  who  accounted  for  approximately  28%  and  42% of
consolidated  operating revenues for the years ended November 30, 1997 and 1996,
respectively.

16. DISCLOSURE OF FAIR VALUE OF FINANCIAL INSTRUMENTS

     At  November  30,  1998 and  1997,  the  carrying  value  of our  financial
instruments,  which primarily include notes payable,  approximates fair value in
management's opinion because of the frequency of their repricing.

17. SUBSEQUENT EVENTS

     On January  29, 1999 at our annual  stockholders  meeting,  a  one-for-five
reverse split of common stock was approved.  Par value and the authorized number
of shares remained at $0.01 per share and 100,000,000, respectively. The reverse
split became  effective at 12:01 a.m. Eastern Standard Time on February 2, 1999.
After the reverse split we had  approximately  4,934,000  shares of common stock
outstanding.  Earnings  per  share,  weighted  average  number of common  shares
outstanding,  and all other  disclosures  regarding  our  stockholders'  equity,
common  stock and  related  stock  option  and  warrant  plans  for all  periods
presented reflect the effects of the reverse split.

     In February,  1999, Norton Mexico suspended drilling operations after being
verbally  informed that the three contracts under which it was operating were to
be canceled.  The original contracts which provided for the drilling of 38 wells
in the  northern  border  states  of Nuevo  Leon and  Tamaulipas,  Mexico,  were
expected to be completed in mid 1999. Only 12 of the 38 wells had been completed
and 3 more were in progress when  operations  were  suspended.  We are currently
investigating  the  possibility of continuance of the  aforementioned  contracts
and/or  possible redeployment of the rigs into the Permian  Basin region of west
Texas.

     Considering  the current  adverse  conditions  in the industry in which the
company operates (e.g., the significant decrease in worldwide oil prices and the
resulting downturn in the demand for contract driling services),  management has
addressed the covenant  provision  within its loan  agreements  with the lending
bank. The bank has reduced the net worth requirement to $6,000,000.

       interest and as to the contract or transaction are disclosed or are known
       to the Board of Directors or the committee, and the Board of Directors or
       committee in good faith  authorizes  the contract or  transaction  by the

       contract or  transaction  are disclosed or are known to the  stockholders
       entitled  to vote there  thereon,  and the  contract  or  transaction  is

Other Than Those by or in the Right of the Corporation.  Subject to Section 3 of
this Article VIII, the  Corporation  shall  indemnify any person who was or is a
party  or is  threatened  to be  made a  party  to any  threatened,  pending  or
completed action, suit or proceedings whether civil criminal,  administrative or
investigative  (other than an action by or in the right of the  Corporation)  by
reason of the fact that he is or was a director  or officer of the  Corporation,
or is or was a director or officer of the Corporation  serving at the request of
the  Corporation  as a  director  or  officer,  employee  or  agent  of  another
corporation,  partnership,  joint venture, trust, employee benefit plan or other
enterprise,  against expenses (including attorneys' fees), judgments,  fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action,  suit or  proceeding if he acted in good faith and in a manner
he  reasonable  believed  to be in or not opposed to the best  interests  of the
Corporation,  and,  with respect to any criminal  action or  proceeding,  had no
reasonable  cause to believe his conduct was unlawful.  The  termination  of any
action, suit or proceeding by judgments order,  settlements conviction or upon a
plea of nolo  contendere  or Its  equivalent,  shall not,  of it self,  create a
presumption  that the person did not act in good faith and in a manner  which he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
Corporation,  and,  with  respect  to any  criminal  action or  proceeding,  had
reasonable cause to believe that his conduct was unlawful.

             Section 2. Power to Indemnity in Actions,  Suits or  Proceedings by
or in the Right of the  Corporation.  Subject to Section 3 of this Article VIII,
the  Corporation  shall  indemnify  any  person  who  was  or is a  party  or is

reason of the fact that he is or was a director  or officer of the  Corporation,
or is or was a director or officer of the Corporation  serving at the request of
the  Corporation  as  a  director,   officer,   employee  or  agent  of  another
corporation,  partnership,  joint venture, trust, employee benefit plan or other
enterprise against expenses (including  attorneys' fees) actually and reasonably
incurred by him in  connection  with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably

                             Page 79 of 141 Pages

<PAGE>



believed  to be in or not  opposed  to the best  interests  of the  Corporation;
except that no  indemnification  shall be made in respect of any claim, issue or
matter as to which  such  person  shall have been  adjudged  to be liable to the
Corporation  unless and only to the  extent  that the Court of  Chancery  or the
court in which such action or suit was brought shall determine upon  application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

             Section 3. Authorization of  Indemnification.  Any  indemnification
under  this  Article  VIII  (unless  ordered  by a  court)  shall be made by the
Corporation  only as authorized in the specific case upon a  determination  that
indemnification  of the  director  or  officer  is proper  in the  circumstances
because he has met the applicable  standard of conduct set forth in Section 1 or
Section 2 of this Article VIII, as the case may be. Such determination  shall be
made (i) by the Board of Directors by a majority vote of a quorum  consisting of
directors who were not parties to such action,  suit or  proceeding,  or (ii) if
such  a  quorum  is  not  obtainable,   or,  even  if  obtainable  a  quorum  of
disinterested  directors so directs,  by independent  legal counsel in a written
opinion, or (iii) by the stockholders. To the extent however, that a director or
officer of the  Corporation  has been  successful  on the merits or otherwise in
defense of any action, suit or proceeding  described above, or in defense of any
claim,  issue  or  matter  therein,  he shall be  indemnified  against  expenses
(including   attorneys'  fees)  actually  and  reasonably  incurred  by  him  in
connection  there with without the  necessity of  authorization  in the specific
case.

             Section 4. Good Faith  Defined.  For purposes of any  determination
under  Section 3 of this Article VIII, a person shall be deemed to have acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the  Corporation,  or, with respect to any criminal  action or
proceeding, to have had no reasonable cause to believe his conduct was unlawful,
if his action is based on the records or books of account of the  Corporation or
another  enterprise,  or on  information  supplied to him by the officers of the
Corporation  or  another  enterprise  in the course of their  duties,  or on the
advice  of  legal  counsel  for the  Corporation  or  another  enterprise  or on
information  or records  given or  reports  made to the  Corporation  or another
enterprise by an independent  certified public  accountant or by an appraiser or
other  expert  selected  with  reasonable  care by the  Corporation  or  another
enterprise.  The term "another  enterprise" as used in this Section 4 shall mean
any other corporation or any partnership, joint venture, trust, employee benefit
plan or other  enterprise  of which such person is or was serving at the request
of the Corporation as a director,  officer, employee or agent. The provisions of
this  Section 4 shall not be deemed to be  exclusive  or to limit in anyway  the
circumstances  in  which a  person  may be  deemed  to have  met the  applicable
standard of conduct set forth in Sections 1 or 2 of this  Article  VIII,  as the
case may be.

             Section  5.  Indemnification  by  a  Court.  Not  withstanding  any
contrary  determination  in the  specific  case under  Section 3 of this Article
Viii,  and  notwithstanding  the absence of any  determination  thereunder,  any
director  or officer  may apply to any court of  competent  jurisdiction  in the
State of Delaware for indemnification to the extent otherwise  permissible under
Sections 1 and 2 of this Article VIII.  The basis of such  indemnification  by a
court  shall  be a  determination  by such  court  that  indemnification  of the
director  or  officer  is proper  in the  circumstances  because  he has met the
applicable  standards  of conduct set forth in  Sections 1 or 2 of this  Article
VIII, as the case may be. Neither a contrary  determination in the specific case
under  Section  3 of this  Article  VIII nor the  absence  of any  determination
thereunder  shall be a defense to such  application or create a presumption that
the  director  or officer  seeking  indemnification  has not met any  applicable
standard of conduct.  Notice of any application for indemnification  pursuant to
this Section 5 shall be given to

                             Page 80 of 141 Pages

entitled to be paid the expense of prosecuting such application.

director  or officer in  defending  or  investigating  a  threatened  or pending
action,  suit or proceeding  shall be paid by the  Corporation in advance of the
final  disposition  of  such  action,  suit or  proceeding  upon  receipt  of an
undertaking  by or on behalf of such director or officer to repay such amount if
it shall  ultimately be determined  that he is not entitled to be indemnified by
the Corporation as authorized in this Article VIII.

             Section 7.  Nonexclusivity  of  Indemnification  and Advancement of
Expenses. The indemnification and advancement of expenses provided by or granted
pursuant to this Article VIII shall not be deemed  exclusive of any other rights
to which  those  seeking  indemnification  or  advancement  of  expenses  may be
entitled  under  any  By-Law,  agreements  contracts  vote of  stockholder's  or
disinterested directors or pursuant to the direction (howsoever embodied) of any
court of competent jurisdiction or otherwise,  both as to action in his official
capacity and as to action in another  capacity  while  holding  such office!  it
being  the  policy  of the  Corporation  that  indemnification  of  the  persons
specified  in Sections 1 and 2 of this Article VIII shall be made to the fullest
extent permitted by law. The provisions of this Article VIII shall not be deemed
to preclude the indemnification of any person who is not specified in sections 1
or 2 of this Article Viii but whom the  Corporation  has the power or obligation
to indemnify  under der the  provisions  of the General  Corporation  Law of the
State of Delaware, or otherwise

liability under the provisions of this Article VIII.

corporation,  any  constituent  corporation  (including  any  constituent  of  a
constituent)  absorbed  in a  consolidation  or merger  which,  if its  separate

directors or officers, so that any person who is or was a director or officer of

are lost to Contractor through confiscation,  expropriation,  nationalization or
governmental seizure; or (iii) are seized or damaged or destroyed as a result of
insurrection,  terrorists  acts,  dot or war (declared or  undeclared)  or other

spare parts and supplies  directly  associated  therewith,  Contractor agrees to
repay to Operator  such  amounts as Operator may have paid to  Contractor  under
this Clause 1409,  less such amounts,  if any, as may be required to restore the

deterioration, and/or depreciation thereof during the period of nonuse resulting
from the causes set forth in this Clause 1409.  In the event of such  resumption
of  possession  of the Drilling rig by  Contractor,  if Operator has  previously
received  title to said Drilling Rig,  Operator shall reassign all of its right,
title and  interest in said  Drilling Rig to  Contractor  as of the time of such
resumption of possession.

Operator's  approval prior to the issuance  thereof.  The cost of such insurance
shall be paid by Operator to  Contractor  within  twenty (20) days after invoice

expropriation,  etc., which  Contractor  receives and for which Operator has not
already  received  credit after  payment has been made by Operator to Contractor
under Clause 1409.
