   ITEM 1.  BUSINESS

   (a)  General Development of Business

             Mexican Industrial Waste Treatment and Disposal Business.  Since
   November  1991,  the Company has been actively involved in the development
   and  operation  of  integrated  industrial  waste  treatment  and disposal
   facilities  in  various states in the Republic of Mexico.  The business is
   comprised  of three major components: industrial waste services, treatment
   and disposal, and development.

        Industrial waste services are conducted by Administracion de Residuos
   Industriales,  S.A. de C.V. ( ARI ).  ARI s business is comprised of waste
   collection,  placement and servicing of parts-washing machines, recycling,
   fuels  blending  and  transportation.    ARI  currently operates through a
   n e twork  of  branch  offices,  strategically  located  in  Mexico  City,
   Guadalajara,  Puebla,  Tampico,  Monterrey,  Guanajuato,  San Luis Potosi,
   Veracruz  and Coatzacoalcos.  In addition, it operates a fuel blending and
   recycling facility in Tenango. ARI s headquarters are in Mexico City.

             Treatment and disposal operations have not progressed beyond the
   development   stage.  The  Company  s  completed  landfill  and  treatment
   facility,  known  as   El Confin , located in the State of San Luis Potosi
   has  not  been  allowed  by  the Mexican government to open and now is the

   <PAGE>                                    1
<PAGE>






   subject  of  the  Company  s  claim  under  the  North American Free Trade
   Agreement  (  NAFTA ).  See  Item 3 - Legal Proceedings  and Note C of the
   Financial Statements.

          Since 1997, the Company has been developing another waste treatment
   and  disposal facility in the State of Aguascalientes.  Construction began
   in  February  1998 but was interrupted in September 1998 by protestors and
   r e m a i n ed  inactive  through  year-end.    The  state  government  of
   Aguascalientes has been alternately willing and unwilling to enforce their
   laws and protect the Company s investment.  On October 1, 1998 the Company
   announced  that it would suspend further investment in Mexico and it would
   stop  further attempts to develop and construct the Aguascalientes project
   until  the  settlement  of  the  Company s NAFTA claim and until the state
   government  of  Aguascalientes demonstrated a willingness to enforce their
   laws and protect the Company s investment.  The project as of this writing
   is approximately 90% complete. 

             Another  expression  of  the  opposition  of the Mexican Federal
   Government  to  the  Company  and  its  projects  is  demonstrated  by the
   unwillingness  of  the federal development bank, Banco Nacional De Obras Y
   Servicios  Publicos,  S.N.C.  (BANOBRAS),  to  approve  financing  for the
   Company  s  project  in  Aguascalientes.   The Company received conceptual
   approval  for  financing in August 1997 and had expected final approval on
   February 25, 1998.  Because of a request made by a senior Mexican official
   the  bank  has  indicated  it would have to  review  our loan application.
   During  the  remainder  of  the  1998 the Company had no further word from
   BANOBRAS,  and has concluded that the bank has no serious interest in ever
   giving final approval to the Company s request for financing.

             Because  of these most recent experiences in Aguascalientes, and
   because  the  Mexican  Government has not shown any serious willingness to
   settle the Company s NAFTA claim short of final arbitration, on October 1,
   1998  the management of the Company committed to a plan to discontinue its
   Mexican  operations  and  to  seek  to  identify  potential buyers for its
   Mexican  business.    The  Company  s  Mexican  operations  are  now being
   classified  as  discontinued  operations,  held  for  sale.    The Company
   believes it will be able to complete a sale of its Mexican business during
   the  next  twelve months.  The Company is also considering the filing of a
   second  NAFTA claim concerning the Aguascalientes project, but has not yet
   determined a final course of action.

        Development activities in the past have been conducted by Ecosistemas
   Nacionales,  S.A.  de  C.V.  ( ECONSA ).  ECONSA s primary business is the
   development  and  permitting  of  industrial  waste treatment and landfill
   facilities  in  strategic  locations  in  Mexico.    The  Company believes
   ECONSA  s  development activities have value to another company willing to
   complete the projects identified by ECONSA.

   (b)  Subsequent Events

           1.  Since the Company s decision to sell its businesses in Mexico,
   made  in  the  fourth  quarter  of  1998,  the Company has pursued several
   opportunities  and is currently negotiating with parties interested in the
   Company  s  businesses  in  Mexico.   The Company believes that it will be
   successful  in  concluding  its  activities  in Mexico in such a way as to
   obtain return of its investment and still not diminish the potential claim
   the  Company may have against Mexico for its interference in the Company s
   businesses there.   However, no assurances can be given that these efforts
   will be successful.

<PAGE>






            2.  On October 13, 1997, the Company filed its detailed  Memorial
   with  the  NAFTA  Tribunal  hearing the Company s claim related to its  El
   Confin    facility.    On  February  17,  1998,  the United Mexican States
   (  Mexico  )  responded to the Company s claim to the Tribunal by filing a
    Counter-Memorial .  The Company filed a  Reply  brief on August 21, 1998.
   Mexico  must  now file its final brief known as a  Rejoinder  by April 19,
   1999.    The  Company  was  notified  on  March 5, 1999 that a pre-hearing
   conference  has  now  been  scheduled in Washington, D.C. for July 6, 1999
   with  the  final hearing on the case scheduled to take place on August 30,
   1999.    A  final  decision  by the tribunal is expected to follow shortly
   after the final hearing.

             3.  In March 1999 the Company accepted the resignations of three
   Directors  of  the Company, Messrs. Guerra, Morales, and Akle.  There were
   no  disputes  with  any of the resigning Directors but each felt unable to
   m a ke  further  contributions  to  the  Company  given  the  decision  to
   discontinue any further investments in Mexico.  Mr. Guerra will retain his
   position as the Director General of all Mexican operations.  

         4.  Three new Directors were appointed to the Board, effective March
   22,  1999, and all three, plus the two remaining directors, Messrs. Kesler
   and  Dabbene, have agreed to stand for election at the next annual meeting
   tentatively scheduled for June 2, 1999.  The three new directors are:

                   Raymond J. Pacini, President and CEO of California Coastal
   Committee.

            J. Thomas Talbot, owner of the Talbot Company.

             Bruce H. Haglund has previously served as a Director the Company
   and also serves as the Company s Secretary and General Counsel.

        5.  In December 1998, the Company made an offer to all holders of its
   warrants  containing anti-dilution provisions, including the provision for
   adjustment  of the number of underlying shares in the event of a reduction
   in  the  exercise price of its warrants.  The offer made was to freeze the
   number  of  underlying  shares  per warrant, calculated on the basis of an
   exercise  price  of  $1.25,  which  was  the  then current exercise price.
   Additionally,  the  Company  offered  to  reduce the exercise price of the
   resultant  number of underlying shares to $.35.  Lastly, for those holders
   of  warrants who chose to exercise their warrants by January 31, 1999, the
   Company  would  reduce  the  exercise  price  to $.25 and issue additional
   warrants equal to the number of shares acquired by exercise.  In exchange,
   the  anti-dilution  provisions  of the warrants were eliminated related to
   both  price  and  quantity  of  the  underlying shares going forward.  The
   Company  has  received acceptances from over 95% of the warrant holders to
   date.    The  results  of  this transaction are reflected in Note J to the
   accompanying financial statements.

   (c)  Financial Information About Industry Segments

         The Company, through MIC and MEC, is engaged in insulation services,

   <PAGE>                                    4
<PAGE>






   a s b estos  abatement  services,  and  insulation  material  sales,  such
   activities  constituting  one  industry  segment.    The  development  and
   operation  of  the  industrial  waste  treatment  business,  commenced  in
   November  1991 through ECO-MTLC and now conducted by the Company s Mexican
   subsidiaries,  had previously been reported as a separate industry segment
   for  1995,  1996  and  1997  and  is  now  being  reported as discontinued
   operations. 

   (d)  Narrative Description of Business

   Introduction

             Business  in  Mexico.  Since November 1991, the Company has been
   actively  involved  in  doing  business  in Mexico.  The Company s initial
   focus  was  the  development  of facilities for the treatment, storage and
   disposal of industrial hazardous waste.

           During the fourth quarter of 1998, the Company determined that its
   efforts  at  building  its  business  in  Mexico  would  not be allowed to
   succeed.    The  Company  s  investment  in  El  Confin has resulted in an
   arbitration  under  the NAFTA treaty, its investment in Aguascalientes has
   been  blocked  just  prior  to  the  project  s  completion, and its other
   business  has  been  impacted  due  to  the loss of these projects and the
   synergy   they  would  have  provided.    Consequently,  the  Company  has
   determined  that  its  Mexican  businesses must be sold to minimize future
   losses  and  that  any further investment in Mexico should be halted.  The
   Company  will  retain  its investment in El Confin, with the operations of
   ARI and El Llano and the development activities of ECONSA held for sale as
   discontinued operations.

             Business  in the United States. Metalclad Insulation Corporation
   specializes in insulation and asbestos abatement services primarily on the
   West  Coast.  The Company provides labor and material supply services to a
   wide  range  of  industrial  and  commercial clients.  Insulation services
   include  the installation of high- and low-temperature insulation on pipe,
   ducts,  furnaces,  boilers,  and  other  types of industrial equipment and
   commercial  applications.  Asbestos abatement services include removal and
   disposal  of  asbestos-containing  products  in similar applications.  The
   Company  fabricates  specialty items for the insulation industry and sells
   insulation  material  and accessories incident to its services business to
   its  customers  as  well  as  to  other  contractors.    A diverse list of
   clientele  includes  refineries, utilities, chemical/petrochemical plants,
   m a nufacturing  facilities,  commercial/manufacturing  installations  and
   buildings, and various government facilities.

<PAGE>






   Mexican Business

         Due to the Company s decision to discontinue its Mexican development
   and  operational businesses, the Company has no ongoing business in Mexico
   other  than the business being conducted by ARI.  It will continue to hold
   its  investment  in  the  subsidiaries  associated  with El Confin pending
   conclusion  of  the  ongoing NAFTA arbitration proceedings.  Its remaining
   businesses are being held for sale.

   Insulation Contracting Services 

           Background.  The Company's insulation contracting services include
   the  installation  of high- and low-temperature insulation on pipe, ducts,
   furnaces,  boilers,  and  various  other  types  of equipment.  Insulation
   services  are  provided  for  new construction and maintenance of existing
   facilities.    The  Company is a licensed general contractor and typically
   provides   project  management,  labor,  tools,  equipment  and  materials
   necessary to complete the installation.

          The Company usually performs substantially all of the work required
   to   complete  its  contracts,  generally  subcontracting  to  others  the
   scaffolding  and  painting.  In a typical insulation contract, the Company
   obtains  plans  and  specifications prepared by the owner of a facility or
   its  agent.   In projects where the customer is the owner of the facility,
   the  Company  acts as the general contractor.  The Company also works as a
   subcontractor for other general contractors.  Insulation contracts for new
   construction  may  require  one  or  more  years to complete.  Maintenance
   contracts typically extend over a period of one or more years.

             The  Company's  insulation contracting business has historically
   included,  among  other  things,  maintenance,  removal,  repair,  and re-
   installation  of  insulation  on existing facilities and equipment.  These
   activities  included  asbestos removal services in most cases in which the
   insulation  at  such  facilities has included asbestos-containing material
   ("ACM").

             The  Company  removes  all forms of ACM after first treating the
   asbestos  with  water  and a wetting agent to minimize fiber release.  Dry
   removal  is  conducted  in  special  cases  where wetting is not feasible,
   provided  Environmental  Protection  Agency  ("EPA") approval is obtained.
   The  Company's workers also remove pipe insulation by cutting the wrapping
   into  sections  in  an  enclosed  containment  area  or  utilizing special
   " g lovebags"  which  provide  containment  around  the  section  of  pipe
   insulation  being  removed.    In  some  instances,  the  Company performs
   asbestos  removal and provides related re-insulation contracting services,
   including  insulation material sales; in other cases, the Company performs
   only  asbestos removal services.  The Company believes that the removal of
   ACM  provides  the best and most cost-effective solution for most asbestos
   abatement projects.

             Insulation  Contracts.    The  Company  obtains contracts, which
   ordinarily  fall  within one of the types set forth below, on the basis of

   <PAGE>                                    6
<PAGE>






   either competitive bids or direct negotiations: 

             Cost-plus.   These contracts, sometimes referred to as "time and
   materials"   contracts,  generally  provide  for  reimbursement  of  costs
   incurred  by the Company and the payment of a fee equal to a percentage of
   the  cost  of  construction.   They generally provide for monthly payments
   covering  both  reimbursement  for costs incurred to date and a portion of
   the  fee  based  upon the amount of work performed and are customarily not
   subject to retention of fees or costs.

             Fixed-price.    These contracts generally require the Company to
   perform  all  work  for  an  agreed upon price, often by a specified date.
   Such  contracts usually provide for increases in the contract price if the
   Company's  construction  costs increase due to changes in or delays of the
   project  initiated  or  caused  by  the customer or owner or by escalating
   project  labor  rates.    However, absent causes resulting in increases in
   contract prices, the Company takes certain risks associated with its fixed
   prices.    Under  these  types  of contracts the Company receives periodic
   payments  based  on  the  work performed to date, less certain retentions.
   The  amounts retained are held by the customer pending either satisfactory
   completion of the Company's work or in some cases, satisfactory completion
   of the entire project.

        In accordance with industry practice, most of the Company's contracts
   are subject to termination or modification by the customer, with provision
   for  the  recovery  of  costs incurred and the payment to the Company of a
   proportionate  part  of its fees, in the case of a cost-plus contract, and
   overhead  and  profit,  in the case of a fixed price contract.  At various
   times,  contracts  that  the  Company  has  with  its  customers have been
   terminated  or modified.  However, such termination or modification occurs
   in the regular course of the Company's business due to changes in the work
   to  be  performed as determined by the customer.  No single termination or
   modification  has  had or is expected to have a material adverse impact on
   the Company's business.

           Operations and Employee Safety.  All contract work is performed by
   trained  Company  personnel and supervised by project managers trained and
   experienced  in  construction  and  asbestos  abatement.    Each  employee
   involved in asbestos abatement must complete a general training and safety
   program  conducted  by the Company.  Training topics include approved work
   procedures,  instruction  on  protective  equipment  and  personal safety,
   dangers of asbestos, methods for controlling friable asbestos and asbestos
   transportation  and  handling  procedures.    In  addition,  all full-time
   employees  engaged in asbestos abatement activities are required to attend
   a  minimum four-day course approved by EPA and the Occupational Safety and
   Health  Administration  ("OSHA") and all supervisors of abatement projects
   are  required  to  attend  a  nine-hour first aid/CPR/safety course and an
   eight-hour  EPA/AHERA  refresher  course  annually.   Six of the Company's
   full-time  employees  and  43  hourly  employees  have  been  trained  and
   certified as "competent individuals" under EPA regulations relating to the
   training of asbestos abatement workers.  All employees are issued detailed
   training  materials  and  the  Company  typically  conducts  a  job safety

   analysis in the job bidding stage.

            The Company requires the use of protective equipment and sponsors
   periodic  medical  examination  of  all  field  employees.  During removal
   procedures,  ACM  is  generally  wetted  to  minimize  fiber  release  and
   filtration   devices  are  used  to  reduce  contamination  levels.    Air
   monitoring  to  determine asbestos fiber contamination levels is conducted
   on  all abatement projects involving the removal of friable asbestos.  The
   Company  has  a  comprehensive policy and procedure manual that covers all
   a c t i v i ties  of  an  asbestos  abatement  project  and  the  specific
   responsibilities  and implementation of Company procedures and policies to
   be  followed  on  each  project.    The manual is reviewed periodically by
   management and updated to insure compliance with federal, state, and local
   r e gulations,  to  include  information  from  in-house  project  reviews
   findings, and to include updated information regarding industry practices.
   To  separate  its  responsibilities  and  to  limit liability, the Company
   utilizes  third  party,  unaffiliated  laboratories  for asbestos sampling
   analysis and licensed independent waste haulers for the transportation and
   disposal of asbestos waste from its projects.

            Materials and Supplies.  The Company purchases its insulating and
   asbestos  abatement  materials  and  supplies  from  a  number of national
   manufacturers and the Company is not dependent on any one source for these
   materials  and  accessories  used  in its insulation services and asbestos
   abatement business.

        Marketing and Sales

         Insulation Contracting Services.  The Company currently obtains most
   of  its  insulation  contracting  business  from  existing  customers  and
   referrals  by  customers,  engineers,  architects, and construction firms.
   Additional  business  is  obtained  by  referrals  obtained through labor,
   industry, and trade association affiliations.

         Projects are also awarded through competitive bidding although major
   companies  frequently  rely  on selected bidders chosen by them based on a
   variety  of  criteria such as adequate capitalization, bonding capability,
   insurance  carried,  and experience.  The Company is frequently invited in
   this  manner  to  bid  on projects and obtains a significant amount of its
   contracts  through  the competitive bidding process.  The Company believes
   that  its bids are competitively priced and anticipates that in the future
   its  bids  will continue to be competitively priced with bids submitted by
   others.

          The Company's marketing and sales effort emphasizes its experience,
   reputation  for  timely  performance,  and knowledge of the insulation and
   asbestos  abatement  industry.    The  Company  is a member of the Western
   Insulation  Contractors  Association,  the National Insulation Contractors
   Association, and various local business associations. 

         Curtom-Metalclad Joint Venture.  In 1989, the Company entered into a
   j o int  venture  with  a  minority  service  firm,  which  qualifies  for

   <PAGE>                                    8
<PAGE>






   preferential contract bidding because of minority status, with the Company
   owning  a  49% interest in the joint venture.  The joint venture, known as
   "Curtom-Metalclad,"  submits  bids  for  insulation and asbestos abatement
   services.    When contracts are obtained by the joint venture, the Company
   performs  the  work  specified  in  the contract as a subcontractor to the
   joint  venture.    The  Company  also  receives  an interest in 49% of the
   profits or losses of the joint venture.

          Insulation Material Sales.  The current emphasis in this area is to
   primarily  warehouse  and supply material for projects where other Company
   services  are  provided.  The warehoused material is based on economics of
   bulk  purchases  of  the most commonly used products or projected needs on
   future known projects, to handle emergencies, and to supply material sales
   direct to other users as available and when solicited.

            Customers.  The Company's insulation customers are categorized as
   Industrial  or  Commercial.    The  industrial customers are predominately
   public utilities (power, natural gas and water/water treatment), major oil
   companies  for  oil refineries and petrochemical plants, chemical and food
   p r ocessors,  other  heavy  manufacturers,  and  engineering/construction
   c o m p a n ies.    The  Commercial  customers  are  primarily  government
   i n stallations,   schools,   hospitals,   institutions,   an   array   of
   m a nufacturing/commercial  facilities,  and  the  general  or  mechanical
   construction  contractors.    The  Company  anticipates that a significant
   portion  of  its  revenues in 1999 will continue to be from work performed
   for Southern California Edison, ARCO, and Texaco.

             Competition.  Competition in the insulation contracting services
   business  is  intense and is expected to remain intense in the foreseeable
   future.    Competition includes a few national and regional companies that
   provide  integrated  services  and  many regional and local companies that
   provide  insulation and asbestos abatement specialty contracting services.
   Most  of  the  national  and  regional  competitors  providing  integrated
   services  are  well  established and have substantially greater marketing,
   financial, and technological resources than the Company.  The regional and
   local  specialty  contracting  companies  which  compete  with the Company
   either  provide  one  service  or  they  provide  integrated  services  by
   subcontracting  part  of  their  services to other companies.  The Company
   believes  that  the  primary competitive factors in these areas are price,
   technical performance, and reliability.  The Company obtains a significant
   number of its insulation service contracts through the competitive bidding
   process.   The Company believes that its bids are competitively priced and
   anticipates  that in the future its bids will continue to be competitively
   priced with bids submitted by others.

            Insurance and Bonding.  The Company's general liability insurance
   policy  provides  base  coverage  of  $1,000,000 per occurrence and excess
   liability  coverage  of  $10,000,000.  Additionally, the Company maintains
   separate  policies  for  contractor  pollution  coverage  in the amount of
   $10,000,000.    The  Company's  current  insulation and asbestos abatement
   services  customers  do  not  generally  require  performance  bonds.  The
   Company  believes,  however,  that  its  current  bonding arrangements are

   <PAGE>                                    9
<PAGE>






   adequate  for  the  Company's  anticipated  future needs.  The Company has
   always  carried  insurance  for  liability  associated  with  the  sale of
   asbestos  bearing materials.  Because of the age of the Company there have
   been  several  different  insurance  carriers.  As  claims  are  made  for
   liability associated with asbestos those claims are managed by counsel for
   the Company and submitted to the appropriate insurance carrier for defense
   depending  upon  the  date the claim originated.  It has been more than 25
   years  since  the  Company  sold any asbestos bearing material.  Since the
   Company  has not yet exhausted more than 50% of the available coverage the
   Company  believes  that  there is adequate coverage and the Company has no
   material exposure to any future claims.

       Government Regulation

        Insulation Services and Material Sales Regulation.  The Company, as a
   general  contractor  and  insulation  specialty  contractor, is subject to
   regulation  requiring  it  to  obtain  licenses  from  several  state  and
   municipal  agencies.    Other  than  licensing,  the  Company's industrial
   insulation services and material sales business is not subject to material
   or significant regulation.

            Asbestos Abatement Regulation.  Asbestos abatement operations are
   s u b ject  to  regulation  by  federal,  state,  and  local  governmental
   authorities, including OSHA and the EPA.  In general, OSHA regulations set
   maximum asbestos fiber exposure levels applicable to employees and the EPA
   regulations  provide  asbestos  fiber emission control standards.  The EPA
   requires  use of accredited persons for both inspection and abatement.  In
   addition,  a  number  of states have promulgated regulations setting forth
   such  requirements  as  registration  or  licensing  of asbestos abatement
   contractors,  training  courses  for  workers,  notification  of intent to
   u n dertake  abatement  projects  and  various  types  of  approvals  from
   designated  entities.    Transportation  and  disposal activities are also
   regulated.    The Company believes that similar legislation may be adopted
   in other states and in local building codes.

          OSHA has promulgated regulations specifying airborne asbestos fiber
   exposure  standards  for  asbestos workers, engineering and administrative
   controls,   workplace  practices,  and  medical  surveillance  and  worker
   protection  requirements.  OSHA's construction standards require companies
   removing  asbestos  on  construction  sites  to  utilize specified control
   methods to limit employee exposure to airborne asbestos fibers, to conduct
   air  monitoring,  to  provide  decontamination  units and to appropriately
   supervise  operations.   EPA regulations restrict the use of spray applied
   ACM  and asbestos insulation, establish procedures for handling ACM during
   demolition and renovations, and prohibit visible emissions during removal,
   transportation and disposal of ACM.

         The Company believes that it is substantially in compliance with all
   regulations  relating  to its asbestos abatement operations, and currently
   h a s  all  material  government  permits,  licenses,  qualifications  and
   approvals required for its operations.

          Backlog.  The Company's backlog for insulation services at December
   3 1 ,   1998,  and  December  31,  1997  was  $7,200,000  and  $5,500,000,
   respectively.    Backlog  is  calculated in terms of estimated revenues on
   fixed-price and cost-plus projects in progress or for which contracts have
   been  executed.    The Company believes that backlog as of any date is not
   necessarily indicative of future revenues.  The Company estimates that its
   entire  backlog  as of December 31, 1998 will be completed during the next
   twelve months.  The majority of the Company's present business is on cost-
   plus  contracts  for  which  backlog  is  estimated.  The Company fulfills
   product  and  supply  orders  promptly,  and  there  is  no backlog in the
   material sales business.

             Employees.  As of December 31, 1998, the Company had a full-time
   staff  of  14 salaried employees, including one executive officer, project
   managers/estimators, purchasing, accounting, and office staff.

             As  of December 31, 1998, the Company employed approximately 104
   hourly  employees  for insulation contracting services, nearly all of whom
   are  members of the International Association of Heat and Frost Insulators
   and  Asbestos  Workers  ("AFL-CIO").  The Company is a party to agreements
   with various local chapters of various trade unions.  The number of hourly
   employees employed by the Company fluctuates depending upon the number and
   size of projects that the Company has under construction at any particular
   time.    It  has  been  the Company's experience that hourly employees are
   generally  available  for  its  projects, and the Company has continuously
   employed  a  number of them on various projects over an extended period of
   time.    The Company considers its relations with its hourly employees and
   the unions representing them to be good and has experienced no recent work
   stoppages due to strikes by such employees.  Additionally, the trade union
   agreements  the  Company is a party to include no strike, no work stoppage
   provisions.

   ITEM 2.  PROPERTIES

            The Company leases space for its offices and warehouse facilities
   under leases of varying terms at rentals aggregating approximately $14,650
   per  month.  The Company's executive offices are located in Newport Beach,
   California,  which consists of approximately 3,000 square feet leased at a
   current  rate  of  $5,850  per  month.  The Newport Beach lease expires in
   September  2002.    Facilities  in  Anaheim, California house the Southern
   California  industrial  insulation  services  and  the insulation material
   sales  operations.  The Anaheim facility consists of 26,000 square feet of
   office  and  warehouse  space that is leased at the current rate of $9,212
   per  month.    The  Anaheim  lease  expires  in  April and is currently in
   negotiations for renewal.

          The Company owns approximately 145 acres of unimproved land located
   in  Tulare  County, California which is not related to the business of the
   Company and is being held for sale.

            ECOPSA owns an approximately 92-hectare parcel (approximately 227
   acres) of land in Santa Maria del Rio near San Luis Potosi, Mexico.

        COTERIN owns approximately 2,200 acres of land near La Pedrera in the
   Mexican State of San Luis Potosi on which El Confin is located.

   ITEM 3.  LEGAL PROCEEDINGS 

           Given the Company s long history in the insulation business and in
   the  sale of insulation materials, it is subject to various claims related
   to  prior  asbestos related business as well as its current business.  The
   number  of  these claims is over 300, the Company believes it has adequate
   insurance  in  place  and  had  adequate  insurance  in prior years and is
   vigorously  defending all claims.  The Company does not believe that these
   claims,  individually  or  in  the aggregate, will have a material adverse
   effect on its financial condition.  (See Note M.)

             In  May  1997, a jury found Texaco oil refinery, a client of the
   Company,  55%  liable  for  injuries  and damages sustained by a Metalclad
   Insulation  employee while working at the Wilmington, California refinery.
   The  jury determined that Texaco s portion of the damages amounted to $5.5
   million.    Under  terms  of  the  Company s contract with Texaco, certain
   indemnities  may be applied.  The Company had project specific, as well as
   other  insurance policies in effect at the time of the injury.  This award
   has  been  appealed and the ultimate outcome cannot be predicted; however,
   the  Company  maintained  separate,  project-specific  insurance coverage,
   which it believes is adequate to address any potential exposure.

<PAGE>






            On October 2, 1996, having completed a long period of negotiation
   with the Mexican government on the opening of its hazardous waste landfill
   in  San Luis Potosi, Mexico, the Company filed a Notice of Claim under the
   provision  of  the  North  American  Free Trade Agreement.  The notice was
   filed  with  the  International  Center  for  the Settlement of Investment
   Disputes  (ICSID)  in  Washington,  D.C. pursuant to the provisions of the
   NAFTA.    On  January 2, 1997, the Company filed its actual claim with the
   Tribunal, after which a three-member Tribunal was impaneled which includes
   one arbitrator from Mexico, one from the United States and a third, chosen
   jointly by the parties, from Great Britain.  The first hearing was held in
   Washington, D.C. on July 15, 1997 and a number of matters were agreed upon
   by  the  parties  and  a  significant amount of direction was given by the
   Tribunal to the proceedings that would move forward.  

          Pursuant to those understandings, the Company, on October 13, 1997,
   filed  its  Memorial,  which  included  the  Claim and all of the evidence
   supporting  the Claim, including expert witness studies and the like.  The
   b a sis  of  the  Company  s  claim  against  Mexico  is  one  likened  to
   expropriation.  The Company s position is since it is not being allowed to
   operate  a legally authorized project, it has in essence been taken by the
   Mexican  government  and they should, therefore, be responsible for paying
   fair  compensation  under  the  provision  of  the  NAFTA.   A fair market
   valuation  was  done  on behalf of the Company by an expert company, which
   indicated the fair market value of this business was $90,000,000.  

        On October 13, 1997, the Company filed its detailed memorial with the
   NAFTA  Tribunal,  hearing  the  Company  s claim related to its  El Confin
   facility.    On  February  17,  1998, the United Mexican States ( Mexico )
   responded  to the Company s claim to the Tribunal.  On August 21, 1998 the
   Company  filed  its Reply to Mexico and on April 19, 1999 Mexico is due to
   file  its rejoinder.  A pre-hearing conference has been scheduled for July
   6,  1999 with a final hearing date set for August 30, 1999.  A decision is
   expected shortly after the final hearing.  

          The Company has devoted substantial resources in the pursuit of its
   claim  before the NAFTA tribunal.  It has given counsel broad authority in
   the employment of experts and others it feels necessary to properly pursue
   the  Company  s  claim.    The  officers  of  the  Company have also spent
   substantial amounts of time and resources in assisting the Company s NAFTA
   counsel  and will continue to do so to completion.  There is no assurance,
   however,  that  the  Company will be successful.  If it is not, the impact
   will  be  material  and adverse (see Note C).  Management does not believe
   that  a  loss  of  its  arbitration case would cause the Company to become
   insolvent  or  prevent  it  from  conducting  its domestic business, or in
   making acquisitions or mergers with others in similar businesses seeking a
   public market.

   RESULTS OF OPERATIONS

             This discussion and analysis contains forward-looking statements
   within the meaning of Section 27A of the Securities Act and Section 21E of
   the  Exchange Act, which are subject to the  safe harbor  created by those
   sections.    The  Company  s actual future results could differ materially
   from  those  projected  in  the  forward-looking  statements.  The Company
   assumes  no  obligation  to  update the forward-looking statements or such
   factors.

   Presentation of Financial Statements

             The financial statements of the Company reflect the Company s on
   g o i n g    business  in  the  insulation  contracting  segment  and  the
   discontinuance  of its waste management segment in Mexico.  The net assets
   of  the  Company  s  business in Mexico are now classified as discontinued
   operations,  with  the  Company  retaining  its interest in the  El Confin
   facility  pending  resolution  of  its  claim  under the NAFTA.  Financial
   statements  of  prior  periods have been restated to reflect the Company s
   decision to discontinue operations in Mexico.

        With the Company having significant financial transactions in Mexico,
   it  has  been  affected  by  the continued decline of the Mexico peso.  In
   November  1994,  the  value of the peso was 3.4 to the U.S. dollar.  As of
   December  31, 1998, the value of the peso was 9.85 to the U.S. dollar.  As
   of  December  31,  1998,  the  Company  has a foreign currency translation
   adjustment of $(2,140,110) in the equity section of its balance sheet.

   Results of Operations

   General.  Historically, the Company s revenues were generated primarily by
   (i)  revenues  in  the United States from insulation services and sales of
   insulation  products  and  related  materials; and (ii) revenues in Mexico
   from  the  collection  of waste oils and solvents for recycling, rental of
   parts  washing  machines,  brokering the disposal of waste and remediation
   services.  

         As discussed in Note B to the Consolidated Financial Statements, the
   Company committed to a plan to discontinue its operations in Mexico and to
   seek  a  buyer.  While no assurances can be made, it is anticipated that a
   sale  will  be  completed in fiscal 1999.  The following narrative details
   the Company s discontinued operations in Mexico and its ongoing Insulation
   Business.


                     Twelve Months Ended December 31, 1998 
                Compared to Twelve Months Ended December 31, 1997

             Insulation Business.  Total revenues were $10,009,000 in 1998 as
   compared  to  $8,971,000  for  1997, an increase of 12%.  This increase is
   attributed  to  work  performed  under  the  Company s various maintenance
   agreements,  particularly  with ARCO, and the Company s continuing efforts

   <PAGE>                                    17
<PAGE>






   in the commercial insulation market.

             Operating costs and expenses were $8,620,000 in 1998 compared to
   $7,686,000  in  1997 an increase of 12%, attributed to the increased level
   of direct costs associated with higher revenues.


           Selling, general and administrative expenses were $993,000 in 1998
   compared  to  $1,177,000  for  the same period in 1997, a decrease of 16%.
   This  decrease  reflects  the  full  year  results  of  the Company s cost
   reduction program, initiated in 1997.

          Discontinued Operations.  Loss from discontinued operations for the
   year  ended  December  31,  1998  was  $2,301,000  compared  to  a loss of
   $2,311,000  for  1997.    The  1998  loss  includes an accrual of $450,000
   associated  with  the decision to discontinue the Mexican waste management
   business.  Net of this accrual, losses for 1998 declined by 20% from 1997.

            Corporate Expense.  Corporate expenses were $2,685,000 in 1998 as
   compared  to  $2,469,000  for  1997,  an  increase  of  9%, reflecting the
   increased legal and consulting costs associated with the Company s ongoing
   NAFTA arbitration.

         Interest Expense.  Interest expense was $187,000 in 1998 compared to
   interest income of $62,000 for 1997, largely due to the Company s issuance
   of notes and debentures in 1998.

          Consolidated Results.  The net loss for the year ended December 31,
   1998 was $4,778,000 as compared to $4,610,000 for 1997, an increase of 4%.
   T h i s  increased  loss  is  attributable  to  accruals  associated  with
   discontinued  operations  in  Mexico and the costs to pursue the Company s
   NAFTA claim.


                     Twelve Months Ended December 31, 1997 
                Compared to Twelve Months Ended December 31, 1996

         Insulation Business.  Total revenues for the year ended December 31,
   1997  were $8,971,000 compared to $10,144,000 for the same period in 1996,
   a  decline  of  12%.   This decrease can be attributed to lower volumes of
   work  performed  under  the  Company  s various maintenance agreements and
   under  subcontracts  with  Curtom-Metalclad  for  work  at  various Edison
   plants.    In  addition,  demand  for asbestos abatement services has also
   declined.

          Operating costs and expenses were $7,686,000 compared to $9,463,000
   for  the same period in 1996, a decline of 19%.  This decrease is directly
   associated  with  the  decline  in revenues.  Additionally, 1996 contained
   costs associated with overruns on two fixed price projects.

        Selling, general and administrative expenses were $1,177,000 compared
   to  $1,600,000  for  the  same  period  in  1996, a decrease of 26%.  This

   <PAGE>                                    18
<PAGE>






   decline  in expenses is the direct result of steps taken by the Company to
   reduce  its  cost  structure,  including  the elimination of certain staff
   positions.

             Discontinued  Operations.  Loss from discontinued operations was
   $2,311,000  in  1997  versus $1,918,000 in 1996.  The increase in loss was
   due  to  the  expenses associated with the Company s efforts in developing
   new  projects,  the write off of goodwill of approximately $71,000 and the
   expansion of ARI.

        Corporate Expense.  Corporate expense for the year ended December 31,
   1997 was $2,469,000 compared to $3,828,000 for the same period in 1996.

            Interest Expense.  Interest income from continuing operations was
   $62,000 as compared to interest expense of $163,000 for the same period in
   1996.

          Consolidated Results.  The net loss for the year ended December 31,
   1997 was $4,610,000 as compared to $6,783,000 for the same period in 1996,
   a  decrease  of  32%.    This improved performance can be attributed to an
   overall  reduction  in  the  Company  s cost structure as well as improved
   performance in the insulation business.


                      Seven Months Ended December 31, 1996 
                Compared to Seven Months Ended December 31, 1995

             Insulation  Business.  Total revenues for the seven months ended
   December  31,  1996  was  $5,519,000  compared  to $6,910,000 for the same
   period  in  1995,  a  decrease of 20%.  This decrease is attributable to a
   decline  in  the  overall  volume  of  work  performed under the Company s
   various  maintenance  agreements  as  well  as a decline in the demand for
   asbestos  abatement  services.    Income  from  the Curtom-Metalclad joint
   venture  was  $45,000 compared to $0.00 for the same period in 1995 due to
   the increase in Edison work contracted through the joint venture. 

          Operating costs and expenses were $4,816,000 compared to $5,685,000
   for the same period in 1995, a decrease of 15% associated with the decline
   in  revenues.   Selling, general and administrative expenses were $769,000
   compared  to  $1,226,000  representing a decrease of 37% attributed to the
   Company s efforts to control overhead costs.

             Discontinued  Operations.  Loss from discontinued operations was
   $1,473,000  as  compared  to  income of $76,000 in 1995.  This increase in
   loss  was due in large part to the Company s commencement of the expansion
   of  ARI,  which was a joint venture with BFI in 1996, as well as the costs
   associated with the Company s project development activities.

             Corporate Expense.  Corporate expense for the seven months ended
   December 31, 1996 was $1,940,000 as compared to $1,790,000, an increase of
   8%.   This increase is attributed to (a) the initial costs of pursuing the
   Company  s  claim under NAFTA and (b) a reserve established by the Company

   <PAGE>                                    19
<PAGE>






   for certain ongoing litigation.

            Interest Expense.  Interest income from continuing operations was
   $154,000 for the seven months ended December 31, 1996 compared to interest
   expense of $834,000 for the same period in fiscal 1996.  This reduction is
   due  to  the  conversions  of  both  the  Company  s  debt and convertible
   subordinated debentures to shares of common stock.

         Other Expense.  Other expense was $0 as compared to $729,000 for the
   same  period  in  fiscal  1996.    In  1996, other expense represented the
   discount given to debenture holders to induce conversion into common stock
   of the Company.

             Consolidated  Results.   The net loss for the seven months ended
   December  31,  1996 was $3,280,000 as compared to $3,277,000, representing
   no  change.  This comparable performance was achieved despite the start-up
   costs  of  BFI-OMEGA,  NAFTA  litigation  costs  and  litigation  reserves
   included  in  the  current  seven months  net loss, while the seven months
   ended  December 31, 1995 contained a one-time gain of $317,000 for donated
   equipment.

   Liquidity and Capital Resources

             In  November 1991, the Company completed the acquisition of Eco-
   Metalclad,  Inc.  ("ECO-MTLC"), commenced the development of the hazardous
   waste treatment business in Mexico and began advancing cash to its Mexican
   subsidiaries  for use in the Mexican business.  Funding the development of
   the  Company's  Mexican  business  has  required  substantial capital.  To
   obtain  capital  for  the  development  of  the business of the Company in
   Mexico,  the  Company  has made private placements of its common stock and
   convertible  subordinated debentures and has obtained loans from financial
   institutions.

            In August 1997, the Company initiated a warrant exchange program,
   wherein  investors  who  exercised  their  existing  warrants were granted
   additional  replacement  warrants.   Between August 1997 and October 1997,
   910,626 warrants were exercised at $1.50, netting the Company $1,365,939.

        In December 1997, the Company issued $2,200,000 Five Year Zero Coupon
   S e cured  Notes,  netting  the  Company  $1,500,000.    These  notes  are
   convertible  into shares of common stock of the Company and the holder was
   also issued warrants to purchase common stock of the Company (see Note G).
   These  notes  are  secured  by  100%  of the stock of Metalclad Insulation
   Corporation.

             In  July  1998,  the Company issued $1,000,000 in 7% Convertible
   Debentures due in July 2001, netting the Company $875,000 (see Note H).

             In  August  1998, the Company issued $350,000 in 10% Convertible
   Subordinated  Debentures  due in August 2001, netting the Company $308,000
   (see Note H).


   <PAGE>                                    20
<PAGE>






            The Company had a working capital deficit at December 31, 1998 of
   $376,000  compared  to working capital of $1,914,000 at December 31, 1997.
   The Company had cash and cash equivalents at December 31, 1998 of $524,000
   and  $1,533,000  at December 31, 1997.  Cash used in continuing operations
   for  the  twelve months ended December 31, 1998 was $1,236,000 compared to
   $1,580,000  for 1997.  Cash used by discontinued operations for the twelve
   months  ended  December 31, 1998 was $1,012,000 compared to $1,944,000 for
   1997.    Cash  used  in  operating  activities for the twelve months ended
   December  31,  1998  was  funded primarily by cash and cash equivalents on
   hand  at  the  beginning  of the year as well as debt financings completed
   during  1998;  however, no assurances can be given that such funds will be
   available to the Company as required.

             The  Company believes that the insulation business will generate
   adequate  cash  flows  from  operations to meet its future obligations and
   expenses  relating  to  such  operations.  For the year ended December 31,
   1998  the  insulation  business  generated  cash  flow  from operations of
   $832,000.    The  Company will require substantial additional financing to
   continue  pursuit of its NAFTA claim, and complete the sale of its Mexican
   operations,   along  with  general  and  administrative  expenses  without
   revenues  to  offset  such expenses.  The Company is aware of its on going
   cash  needs  and  continues  to  work with its warrant holders, investment
   bankers  and other sources to meet its on going needs through December 31,
   1999.    Given the Company s decision to discontinue operations in Mexico,
   and sell its businesses, the cash requirements in Mexico greatly diminish.
   The  Company  believes  it will obtain the necessary funds to continue its
   planned operations throughout 1999.

   Impact of Inflation

             The  Company reflects price escalations in its quotations to its
   insulation  customers  and  in  its  estimation of costs for materials and
   labor.    For  construction  contracts  based  on a cost-plus or time-and-
   materials  basis,  the  effect  of inflation on the Company is negligible.
   For projects on a fixed-price basis, the effect of inflation may result in
   reduced profit margin or a loss as a result of higher costs to the Company
   as  the  contracts  are  completed; however, the majority of the Company's
   contracts  are  completed  within  12 months of their commencement and the
   Company  believes  that  the  impact  of  inflation  on  such contracts is
   insignificant.

             Although  inflation has been a significant factor in the Mexican
   economy  in general since the devaluation, the Company does not anticipate
   that  it  will  have  a  material  impact  on  its  current  or  remaining
   operations.

   Year 2000 Issues

            During fiscal 1998, the Company initiated a plan to implement new
   business  information  systems,  which  will address all year 2000 issues.
   This plan included updating hardware and software necessary to comply with
   the issues associated with year 2000.  This implementation did not require

   <PAGE>                                    21
<PAGE>






   any significant capital expenditures during fiscal 1998 and no significant
   e x p enditures  are  anticipated  in  1999.    In  the  event  that  this
   implementation  is not completed prior to the year 2000, the Company has a
   contingency  plan, pursuant to which, existing systems will be modified to

   its principal accountants, Arthur Andersen LLP and approved the engagement
   of  Moss Adams LLP as its new principal accountants.  During the Company s
   past two fiscal years, there were no disagreements between the Company and

   Andersen s report on the financial statements of the Company was qualified
   relative to the Company s ability to continue as a going concern given its
   recurring losses and large accumulated deficit.

   ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

          In October 1994, in consideration of extraordinary contributions to
   the  Company, including but not limited to the pledge of 755,000 shares of
   common  stock  of  the  Company  owned  by  them  to  facilitate necessary
   financings  for  the  Company,  the board of Directors approved  a loan of
   $370,000 to each of Mr. Kesler and Mr. Neveau.  Such borrowings are due 30
   days  after  demand and bear annual interest at the prime rate of interest
   plus  7%.    The  borrowings  are secured by a pledge of 300,000 shares of
   common  stock  from  each  borrower.   In February 1996 Messrs. Kesler and
   Neveau each repaid $150,000 to the Company.  In March 1996, the notes were
   amended  to modify the loan principal between Messrs. Kesler and Neveau as
   well  as  to  adjust  the  interest  rates,  effective  March 1, 1996 to a
   variable  rate  based  upon  the  Company  s  quarterly  investment  rate.
   Repayment of these notes has been extended until December 31, 1999.

         In June 1996, Mr. Neveau, Chairman of the board of Directors, Senior

   <PAGE>                                    23
<PAGE>






   Vice  President,  and  a  Director  of  the Company, resigned his position
   effective  the  next  shareholders  meeting.  As a result, the Company and
   Mr.  Neveau renegotiated the terms of his employment agreement relative to
   compensation, benefits and stock options.  Since May 1997, the Company has
   been  offsetting  payments  due  Mr.  Neveau  against his outstanding loan
   balance  to  the  Company.  There are no remaining payments due Mr. Neveau
   and his indebtedness to the Company as of December 31, 1998 was $67,200.

        During the twelve months ended December 31, 1998, the Company accrued
   legal  fees  of $74,000 from the law firm of Gibson, Haglund & Johnson, of
   which  Bruce  H.  Haglund, general counsel, Director, and Secretary of the
   Company, is a principal; however, none of such fees have been paid.

             During December, 1996, the Company loaned $150,000 to Mr. Javier
   Guerra Cisneros, a Director and Vice President of Mexico operations.  This
   loan is evidenced by a promissory note bearing interest at 10% and secured
   by  a  pledge  of  future salary and 300,000 shares of common stock in the
   Company.    In  February  1997,  Mr.  Guerra repaid $120,000 of this loan.
   Repayment  of this note has been extended to the earlier of the completion
   of the sale of the Mexican operations or December 31, 1999.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

   The Board of Directors and Shareholders of Metalclad Corporation:

   We  have  audited the accompanying consolidated balance sheet of Metalclad
   Corporation  (a  Delaware Corporation) and subsidiaries as of December 31,
   1998,  and the related consolidated statements of operations, shareholders
   equity  and  cash  flows  for  the  year  ended  December 31, 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 audit.

   We  conducted  our  audit  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 audit
   provides a reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly,
   in  all material respects, the financial position of Metalclad Corporation
   and  subsidiaries  as  of  December  31,  1998,  and  the results of their
   operations  and  their  cash flows for the year ended December 31, 1998 in
   conformity with generally accepted accounting principles.

   The accompanying financial statements have been prepared assuming that the
   Company  will  continue as a going concern.  As discussed in Note A to the
   financial  statements,  the  Company  has  suffered  recurring losses from
   operations  and  has  a  large accumulated deficit that raises substantial
   doubt  about  its  ability  to  continue as a going concern.  Management s
   plans  in  regard  to  these  matters  are  also described in Note A.  The
   financial  statements  do  not  include  any  adjustments  relating to the
   recoverability  and classification of asset carrying amounts or the amount
   and  classification of liabilities that might result should the Company be
   unable to continue as a going concern.

   Our  audit  was  made  for  the purpose of forming an opinion on the basic
   financial  statements  taken as a whole.  The schedule listed in the index
   of  financial  statements  is presented for purposes of complying with the
   Securities  and  Exchange  Commission s rules and is not part of the basic
   financial  statements.   The data for the year ended December 31, 1998 has
   been  subjected  to  the  auditing  procedures applied in the audit of the
   basic  financial  statements  and,  in  our  opinion,  fairly state in all
   material  respects  the financial data required to be set forth therein in
   relation to the basic financial statements taken as a whole.

   We  have audited the accompanying consolidated balance sheet of Metalclad Corporation (a

   consolidated  statements of operations, shareholders  equity and cash flows for the year

   financial  statements  and,  in  our opinion, fairly states in all material respects the
   financial  data  required  to  be  set  forth therein in relation to the basic financial
   statements taken as a whole.

   NOTE A   DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

   Description of Business

   Metalclad  Corporation  (the  Company ) is engaged in insulation services,
   including asbestos abatement and material sales, to customers primarily in
   California (the  Insulation Business ).  The Company has also been engaged
   in  the  development  of  hazardous  and  non-hazardous  industrial  waste
   treatment  and storage facilities, as well as the collection and recycling
   of  industrial  waste for disposition to landfills or as alternative fuels
   for cement kilns in Mexico (the  Mexican Business ).

   On  October  13,  1997,  the Company filed a claim for arbitration against
   Mexico  under  provisions  of  the  North  American  Free  Trade Agreement
   (  NAFTA  ).    The claim alleges the Company has been denied the right to
   operate its permitted and fully constructed landfill facility in the State
   of  San  Luis  Potosi,  thereby causing the facility to be, as a practical
   matter,  expropriated.    The  Company believes it is entitled to the fair
   market value of the facility as damages.  A final hearing on the Company s
   claim  has  been scheduled to commence on August 30, 1999, with a decision
   anticipated  shortly  thereafter.    The decision in the NAFTA arbitration
   will  be  material  to the Company, however, no assurances can be given of
   the Company being successful.

   Because  of  this  arbitration,  the Company s other businesses in Mexico,
   including  its  development  of a second landfill facility in the State of
   Aguascalientes,  have  been  impacted  dramatically.    Consequently,  the
   Company  is  discontinuing any further investment in Mexico and is seeking
   to sell its remaining businesses in Mexico.  (See Note B.)

   The  accompanying  financial  statements  have  been prepared assuming the
   Company  will  continue  as  a  going  concern.  As shown in the financial
   statements,  the Company has incurred recurring losses from operations and
   has  a  large  accumulated deficit.  Additionally, the Company may require
   substantial  additional  financing  to pursue its NAFTA claim, the sale of
   its  Mexican  businesses  and  to fund general and administrative expenses
   without  sufficient  revenues  to offset.  These matters raise substantial
   doubt  about  the  Company  s ability to continue as a going concern.  The
   Company  is  continuing  its  efforts  to  reduce costs and has halted any
   further  funding  for  development  in  Mexico.    The Company is pursuing
   additional  financing  alternatives  to  maintain its operations which may
   include  a  continuation  of  its warrant exchange program.  The financial
   s t a t e ments  to  do  not  include  any  adjustments  relating  to  the
   recoverability  of asset carrying amounts or the amount and classification
   of  liabilities that might result should the Company be unable to continue
   as a going concern.

   Principles of Consolidation/Investments

   The  consolidated financial statements include the accounts of the Company
   and  its  wholly-owned  subsidiaries.   Investments in other companies and
   joint  venture  corporations  which  are  20-50% owned are reported on the

   <PAGE>                                   F7
<PAGE>






   equity  method.  Significant  intercompany  accounts and transactions have
   been  eliminated  in  consolidation.    Costs  incurred  relating  to  the
   acquisition  or  formation  of  an equity method investment are considered
   part of the investment and are amortized over five years.

   Contracts in Process

   Fixed  price  insulation installation and asbestos abatement contracts are
   accounted  for  by  the  percentage-of-completion method wherein costs and
   estimated  earnings are included in revenues as the work is performed.  If
   a  loss  on  a fixed price contract is indicated, the entire amount of the
   estimated  loss  is  accrued  when known.  Time and material contracts are
   accounted  for under a cost plus fee basis.  Retentions by customers under
   contract terms are due at contract completion.

   Inventories

   Inventories,  which consist principally of insulation products and related
   materials,  are  stated  at the lower of cost (determined on the first-in,
   first-out method) or market.

   Depreciation and Amortization

   Property,  plant  and  equipment  is  stated  at  cost.   Depreciation and
   amortization is computed using the straight-line method over the estimated
   useful  lives  of  related  assets  which range from between five to seven
   years for machinery, equipment and leasehold improvements.

   Goodwill

   Goodwill  represents  the  excess  purchase  price  over the fair value of
   certain  landfill  assets  acquired in 1994 and is being amortized over 10
   years.  (See Note C.)

   Cash Equivalents

   The   Company  considers  all  highly  liquid  investments  with  original
   maturities  of  three months or less to be cash equivalents.  The carrying
   amount  approximates  fair  value  because  of the short maturity of those
   instruments.

   Loss Per Share

   The Company computes loss per share in accordance with SFAS 128,  Earnings
   Per  Share  .   This statement requires the presentation of both basic and
   diluted  net  loss  per share for financial statement purposes.  Basic net
   loss   per  share  is  computed  by  dividing  loss  available  to  common
   stockholders  by the weighted average number of common shares outstanding.
   Diluted  net  loss  per  share includes the effect of the potential shares
   outstanding,  including  dilutive  stock  options  and  warrants using the
   treasury  stock  method.    Because the impact of options and warrants are
   anti-dilutive,  there  is no difference between the loss per share amounts

   <PAGE>                                   F8
<PAGE>






   computed for basic and diluted purposes.

   Stock-Based Compensation

   Effective  June  1, 1996, the Company adopted the disclosure provisions of
   SFAS  No.  123,    Accounting for Stock-Based Compensation .  SFAS No. 123
   requires  the  Company  to  disclose pro forma net income and earnings per
   share  as  if  the  fair value based accounting method of SFAS No. 123 had
   been  used to account for stock based compensation.  These disclosures are
   included in Note J.

   Income Taxes

   The  Company  accounts  for  income  taxes  using  the liability method as
   prescribed  by  Financial  Accounting  Standards  No. 109,  Accounting for
   Income Taxes . 

   Comprehensive Income

   In  1998,  the Company adopted SFAS 130,  Reporting Comprehensive Income .
   This statement establishes rules for the reporting of comprehensive income
   and  its  components.    Comprehensive  income  consists of net income and
   f o reign  currency  translation  adjustments  and  is  presented  in  the
   Consolidated  Statement of Shareholders  Equity.  The adoption of SFAS 130
   had  no  impact  on  total  shareholders    equity.  Prior  year financial
   statements have been reclassified to conform to the SFAS 130 requirements.

   Foreign Currency Translation

   Through  December  31,  1996,  all  assets  and liabilities of the Mexican
   subsidiaries were translated at the current exchange rate as of the end of
   the  accounting  period.    Items  in  the  statements  of operations were
   translated  at  average currency exchange rates.  The value of the Mexican
   Peso  relative  to the U.S. Dollar declined from approximately 3.4 Mexican
   Pesos  in June 1994 to approximately 9.85 Mexican Pesos to the U.S. Dollar
   at December 31, 1998.  The resulting translation adjustments were recorded
   as a separate component of shareholders  equity.

   As  of  January  1,  1997,  Mexico  has  been deemed a highly inflationary
   economy.    This  results in the U.S. dollar being the functional currency
   of  the  Company  s  Mexican  entities and the net exchange gain or losses
   resulting  from  the  translation of assets and liabilities of the Mexican
   entities  now being included in income, except for the effects of exchange
   rate changes on intercompany transactions of a long-term investment nature
   which are still recorded as a separate component of shareholders  equity.

   Reclassifications

   Certain  reclassifications  have  been  made  to prior period consolidated
   financial statements to conform with the current year presentation.

   Use of 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.


   NOTE B   DISCONTINUED OPERATIONS

   During  the  year ended May 31, 1994, the Company formed a Mexican holding
   company, Ecosistemas Nacionales, S.A. de C.V. (ECONSA), to ultimately hold
   the  common  stock  of  Ecosistemas  del  Potosi,  S.A.  de C.V. (ECOPSA),
   Confinamiento  Tecnico  de  Residuos Industriales, S.A. de C.V. (COTERIN),
   Consultoria  Ambiental Total, S.A. de C.V. (CATSA), Quimica Omega, S.A. de
   C.V.  (QUIMICA  OMEGA),  Administracion  de Residuos Industriales, S.A. de
   C.V. ( ARI ) and Ecosistemas El Llano, S.A. de C.V. ( El Llano ).

   During  the fourth quarter of 1998, management committed to a plan to sell
   its  Mexican  operations  to a third party.  Consequently, this segment of
   the  Company  s business is now being reported as discontinued operations.
   Although  the exact timing is difficult to predict, the Company expects to
   sell  its  interest  in  ARI, El Llano and ECONSA s development activities
   during fiscal year 1999.

   The  loss  from  discontinued  operations  during  fiscal  1998 includes a
   provision  for  anticipated  closing  costs  and  operating  losses  until
   disposal  of  $450,000.    Based  on  information currently available, the
   Company  does  not anticipate that it will incur a loss on the sale of the
   reported net assets of the discontinued operations.

   The consolidated financial statements for prior periods have been restated
   to reflect the accounting for discontinued operations.

   Net sales and loss from discontinued operations are as follows:

   NOTE C - REALIZATION OF ASSETS

   The  Company  addresses  the realization of its assets as required by SFAS
   121  Accounting for the Impairment of Long-Lived Assets and for Long-Lived
   Assets to be Disposed of .  This statement requires that long-lived assets
   and  certain  identifiable intangibles to be held and used be reviewed for
   impairment  whenever  events or changes in circumstances indicate that the
   carrying  value  of  an  asset  may  not  be recoverable.  The Company has
   conducted this review and believes that no impairment currently exists and
   no material adjustments are necessary to the valuation of its assets.

   El Confin

   Included  in  property,  plant and equipment, net at December 31, 1998, is
   approximately  $4,323,000  representing  the  Company  s investment in its
   completed  hazardous  waste  treatment  facility  in the State of San Luis
   Potosi,  Mexico,  known  as    El  Confin .  Additionally, the Company has
   unamortized  goodwill  of  approximately  $507,000  associated  with  this
   facility.  The Company has been granted all necessary federal governmental
   authorizations  to  open  and  operate  the  facility but, as yet, has not
   received the support of the state and local governments.  Consequently, on
   October  2, 1996, the Company filed a Notice of Intent to File Claim Under
   the  North  American  Free Trade Agreement ( NAFTA ).  The Claim was filed
   with  the  International  Centre  for  Settlement  of  Investment Disputes
   (  ICSID ) in Washington, D.C.  On January 13, 1997, the Secretary General
   of  ICSID  registered  the  Company  s  claim and notified both the United
   States  and Mexican governments of the registration.  On October 13, 1997,
   the  Company  filed  its  detailed memorial, or claim, and on February 17,
   1998, Mexico filed its counter-memorial, or response.  The Company filed a
   reply  brief  on  August  21,  1998  and  Mexico  is scheduled to file its
   response  on  April  19, 1999.  A final hearing on the issues is scheduled
   for  August  30,  1999.   The Company s claim is one under the category of
     Likened  to  Expropriation   wherein the Company, having been denied the
   right  to  operate  its  constructed  and  permitted  facility, claims its
   property   has  therefore  been,  as  a  practical  matter,  expropriated,
   entitling the Company to the fair market value of the facility as damages.
   Although  the Company remains confident in its position, no assurances can

   <PAGE>                                   F11
<PAGE>






   be  given  that  it  will  be successful in this arbitration process.  The
   realization of the capitalized landfill costs and goodwill associated with
   El Confin is dependent upon a successful resolution of the Company s NAFTA
   claim.    Based upon independent appraisal and management s best estimate,
   the  Company  believes  that  the  proceeds  from  the  NAFTA  claim  will
   significantly exceed the carrying value of the El Confin assets.  However,
   should  a  decision  be  rendered  against  the  Company,  assets totaling
   $4,830,000  may  be  impaired  and could potentially result in a write off
   should the Company be unable to sell or otherwise recover its investment.

   NOTE G   CONVERTIBLE LONG-TERM NOTES

   In  December  1997,  the  Company  issued $2,200,000 Five Year Zero Coupon
   Secured Notes, due December 31, 2002, netting the Company $1,500,000.  The
   Company is amortizing the difference between the value at maturity and the
   purchase  price  over  five years.  Upon the market price of the Company s
   common  stock  closing at or above $1.50 for ten consecutive trading days,
   the notes become convertible into common stock of the Company at $1.50 per
   share  and  the  Company is to issue warrants to purchase 1,500,000 common
   shares  of  stock.    Both the conversion price and warrant exercise price
   also  contain  anti-dilution  provisions.      Additionally, the notes are
   redeemable  at  the  option  of the holder, or the Company, any time after
   April 15, 1999.  These notes are secured by 100% of the stock of Metalclad
   Insulation  Corporation.   In February 1998, the conditions triggering the
   convertibility of the notes and the issuance of warrants were met.

   In  June  1998,  the  Company  registered a bridge loan with the holder of
   these  notes  in  the amount of $250,000.  As additional consideration for
   the bridge loan, the Company issued 250,000 warrants exercisable at $1.25.
   In  connection  with  this  financing, certain amendments were made to the
   original  Five  Year  Zero  Coupon  Notes  which  granted  the  holder  an
   additional  400,000 warrants exercisable at $1.50 and clarifying the anti-
   dilution  language  contained  in the original notes.  The bridge loan was
   paid  in  its  entirety  from  the  proceeds  of  the  Company s July 1998
   financing.    Due  to  the  anti-dilution provisions contained in both the
   notes  and  the  warrants, the holder of these notes had rights similar to
   those of the Company s existing warrant holders.  As part of the Company s
   negotiations  with  the warrant holders to solve the issue of the on going
   anti-dilution effects on the number of shares underlying the warrants, the
   holder  of these notes also had to be addressed to solve the anti-dilution
   provisions  contained in the notes.  In February 1999, the Company and the
   holder  reached agreement on the conversion price of the notes, originally
   priced  to convert at $1.50 per share, and are now convertible into shares
   of the Company s common stock at $.25 per share.

   NOTE H - CONVERTIBLE SUBORDINATED DEBENTURES

   I n    N ovember  1993,  the  Company  issued  $3,840,000  of  convertible
   subordinated  debentures  due  in  60  months,  bearing interest at 9% and
   convertible  into  shares  of  common stock at the rate of $5.50 per share
   subject  to  certain adjustments.  During the year ended May 31, 1994, the
   Company also issued an additional $732,359 principal amount of convertible
   subordinated  debentures  due  in  60  months, bearing interest at 8%, and
   convertible  into  shares  of common stock at the rates of $4.00 and $5.00
   per share subject to certain adjustments.

   In August 1995,  the Company offered to convert all outstanding debentures
   into  shares  of common stock at a conversion price below the stated price
   on  the debentures.  As of May 31, 1996, approximately $8,600,000 of these
   debentures  converted  at  the  rate  of  $2.50  per share and the Company
   recognized  a  charge of $729,000 due to the lower conversion price offer.
   All of these debentures have now either converted or have been retired.

   In  July  1998, the Company issued $1,000,000 in 7% Convertible Debentures
   due  in  July  2001.    The  debentures are convertible into shares of the
   Company common stock at $1.25 or 75% of current market price, whichever is
   lower.    The  Company  has  the  option to redeem all or portions of this
   debenture  at  125%  of  the  principal  amount  of  the  redemption.  The
   debenture  also allows for a mandatory redemption in the event of an award
   in  the  NAFTA  arbitration  or,  in certain cases, if the Company obtains
   additional equity investment.  The mandatory redemption is also at 125% of
   the  then-outstanding  principal  balance.   In February 1999, the Company
   redeemed $150,000 of the principal amount of the debentures.

   I n    August  1998,  the  Company  issued  $350,000  in  10%  Convertible
   S u bordinated  Debentures  due  in  August  2001.    The  debentures  are
   convertible  into  shares of the Company s common stock at $1.25 per share
   through  June  30, 1999.  After June 30, the debentures are convertible at
   75%  of  current market price or $1.25 whichever is lower.  The debentures
   are  also redeemable at the option of the company when the average closing
   bid  and  ask prices of the Company s common stock closes at prices higher
   than $3.00 per share for 20 days in any 30-day period.


   NOTE I - INCOME TAXES

   There  was  no provision for income taxes for the periods presented due to
   losses  incurred  and  the  Company  s inability to recognize certain loss
   carry  forwards.    The  major deferred tax items at December 31, 1998 and
   1997 are as follows:

   The  difference  between the actual income tax benefit and the tax benefit
   computed by applying the statutory Federal income tax rate to the net loss
   before  income  taxes  is  attributable  to  the  inability  to  recognize
   currently the future benefit of net operating loss carryforwards.

   At  December  31,  1998,  the  Company  has available for U.S. Federal and
   California  income  tax  purposes  net  operating  loss  carryforwards  of
   approximately   $19,000,000   and   $7,000,000,   respectively.      These
   carryforward  amounts  expire  in  the  years  2000  through 2018 and 1999
   through  2003,  respectfully.    At  December  31,  1998,  the Company has
   available  investment  credits  of  approximately $32,300 to offset future
   U.S.  Federal  income  tax  liability. The ultimate utilization of the net
   operating  loss  and  investment credit carryforwards may be restricted in
   the  future  due  to changes in the ownership of the Company.  The Company
   also  has  Mexican  net  operating  loss  carryforwards  of  approximately
   $6,000,000  which  may  be  utilized to offset future taxable income.  The
   Mexican  losses  are  subject  to  a  ten-year tax carryforward period and
   expire in the years 2002 through 2008.  

   The  Company  has  recorded  a valuation allowance for that portion of the
   deferred tax asset that the Company does not believe to be realizable.


   NOTE J - SHAREHOLDERS  EQUITY

   Stock Options

   On  August 18, 1992, the Company adopted an omnibus stock option plan (the
    1992 Plan ) which authorized the issuance of 1,600,000 options to acquire
   the  Company  s  common  stock.   At December 31, 1998, there were options
   outstanding under the 1992 Plan for 770,000 shares, and none available for
   grant.  These options will expire 10 years from the date of grant.

   On  March  24, 1993, the Company adopted an omnibus stock option plan (the
    1993 Plan ) which authorized the issuance of 1,000,000 options to acquire
   the  Company  s  common stock.  The terms of the 1993 Plan are the same as
   the 1992 Plan.  At December 31, 1998, there were options outstanding under

   <PAGE>                                   F16
<PAGE>






   the  1993  Plan  for  674,500 shares, and 500 options available for grant.
   These options expire 10 years from the date of the grant.

   On  May  15,  1997,  the Company adopted an omnibus stock option plan (the
    1997 Plan ) which authorized the issuance of 6,000,000 options to acquire
   the  Company  s  common stock.  At December 31, 1998 there were no options
   outstanding under this plan.

   During  the  year  ended December 31, 1998, the Board of Directors and its
   Compensation  Committee  approved the grant to various officers, directors
   and  employees  of  the  Company  of  options  to purchase an aggregate of
   2,463,000  shares  of  common stock.  The options were granted at exercise
   prices equal to or exceeding the fair market value of the Company s common
   stock  on the measurement date, expire 10 years from the date of grant and
   have various vesting schedules.

   NOTE M - COMMITMENTS AND CONTINGENT LIABILITIES

   The  Company has employment agreements with its executive officers.  These
   agreements  continue  until terminated by the executive or the Company and
   provide for minimum salary levels, as adjusted for cost of living changes.
   These agreements include incentive bonuses based upon specified management
   goals, and a covenant against competition with the Company extending for a
   period of time after termination.

   The  Company  leases  its  facilities under non-cancelable operating lease
   agreements which expire at various dates through 2002.  Total rent expense
   under  operating  leases  was  $178,245, $307,839,  $168,722, and $404,647
   for  the  years  ended  December  31,  1998  and  1997, seven months ended
   December  31,  1996  and  for  the years ended May 31, 1996, respectively.
   Future  minimum  non-cancelable lease commitments (assuming renewal of the
   Anaheim lease) are as follows:

              Year ending December 31, 1999   $211,788
                                       2000    237,660
                                       2001    149,878
                                       2002     60,957

                                              $660,283
                                               =======

   In  the  ordinary  course of its insulation business, certain parties have
   filed  a  substantial  number of claims against the Company for actual and
   punitive  damages.  Presently, the number of these claims exceed 300.  The
   potential value of the claims is in the range of $1,000,000 to $5,500,000.
   t h e   Company  continues  to  have  adequate  insurance  coverages  with
   financially sound carriers responding to these claims and does not foresee
   any  financial  exposure  resulting  from  these  claims.   Throughout its
   history,  the  Company  has  maintained  insurance policies that typically
   respond  to  these  claims.    Based  on  the  advice  of  counsel,  it is
   management   s  opinion  that  these  actions,  individually  and  in  the
   aggregate,  will  not  have  a significant adverse impact on the Company s
   financial position or results of operations.

                              EMPLOYMENT AGREEMENT


          This Agreement is entered into this 1st day of January, 1998 by and
   b e tween  METALCLAD  CORPORATION,  a  Delaware  corporation  (hereinafter
   referred  to  as the "Company"), and Grant S. Kesler (hereinafter referred
   to as "Executive") under the following terms and conditions:

                                    RECITALS:

         WHEREAS, the Company and Executive desire to set forth the terms and
   conditions on which (i) the Company shall employ Executive, (ii) Executive
   shall  render  services  to  the  Company,  and  (iii)  the  Company shall
   compensate Executive for such services; and 

             WHEREAS,  in  connection with the employment of Executive by the
   Company,  the  Company  desires  to restrict Executive s rights to compete
   with the business of the Company;

           NOW, THEREFORE, in consideration of the mutual promises, covenants
   and agreements hereinafter set forth, the parties hereto agree as follows:


        1.  EMPLOYMENT.

            The Company hereby employs Executive and Executive hereby accepts
   employment  with the Company upon the terms and conditions hereinafter set
   forth.


        2.  TERM.

            2.1  The term of this Agreement (the "Term") shall be for a three
   year period commencing on the Effective Date (as defined in Subsection 2.3
   below)  of  this  Agreement,  subject, however, to termination as provided
   herein in Sections 6 and 7 below.

               2.2  Each year, prior to the anniversary date, the company and
   executive shall meet to determine any additional compensation, if any, for
   the remaining contract term.

                2.3  The effective date of this Agreement shall be January 1,
   1998 (the "Effective Date").


        3.  COMPENSATION.

            3.1  For all services rendered by Executive under this Agreement,
   the  Company  shall  pay  or  cause one or more of its subsidiaries to pay
   Executive during the term hereof a salary at the rate of Two Hundred Fifty

   <PAGE>                           -1-
<PAGE>




   Thousand  Dollars  ($250,000.00)  per  year.    The Company shall pay such
   compensation  to  Executive  semi-monthly  in accordance with its standard
   practice for payment of compensation to its employees.  

                 3.2  Executive shall be entitled to periodic cash bonuses in
   accordance with the Metalclad Corporation Stock Option and Incentive Plan,
   any  other  incentive  bonus  plans or other forms of compensation, at the
   discretion  of the Company s Board of Directors, dependent upon Employee s
   performance.   Executive shall be entitled to participate in the Company s
   401(k) plan.


                 3.3  Executive shall be entitled to a car allowance, housing
   allowance and to health insurance for him and his dependents.

              3.4  All compensation shall be subject to customary withholding
   t a x  and  other  employment  taxes  as  are  required  with  respect  to
   compensation paid by a corporation to an employee.

                3.5  In order to provide proper incentives to those personnel
   engaged  in  developing waste processing facilities in Mexico, the Company
   recognizes  that  it  must  institute special bonus programs and incentive
   bonus  programs  from  time  to  time.    For  the calendar year 1998, the
   Compensation  Committee  has  approved both a special bonus program and an
   incentive bonus program as follows:

                      3.5.1  Special Bonus Program.  Because of the Company s
   involvement  in  a  NAFTA  arbitration  against  the Federal Government of
   Mexico,  it  requires an extraordinary effort on the part of key employees
   to  ensure  the  success  of the litigation on the part of the Company.  A
   total  of  five percent (5%) of the award, or the value of the settlement,
   is  to be shared with three key executives.  The Executive herein shall be
   entitled to two and one-quarter percent (2.25%) of the total award, or the
   total  value  of  the  settlement  of  the  case,  in the event there is a
   settlement.  

                 3.5.2  Incentive Bonus Program.  For the calendar year 1998,
   the  Board  of  Directors  has  set  three  major  objectives  for the key
   executives.  The objectives include opening the Aguascalientes project for
   commercial  operations,  keeping  the  Company  properly  capitalized  for
   growth,  and  respecting the public market participation in the Company to
   ensure  that  gains  made  by  the  Company  are  recognized by its public
   ownership  and  reflected  in  its  share price.  To the extent that these
   objectives  are  met, the key participants in the incentive bonus program,
   including  the  Executive herein, shall be entitled to a minimum of twenty
   percent (20%) of his base salary to a maximum of one hundred fifty percent
   (150%)  of  base salary, depending upon the extent to which the objectives
   have been achieved.

                  It is expected that the foregoing bonuses will be earned in
   1998,  unless  the  settlement or conclusion of the NAFTA litigation takes
   longer,  in  which  case that particular special bonus will go beyond 1998
   until  there  is  a  final  resolution.   It is expected that the Board of
   Directors will provide additional bonus incentives for years subsequent to




   <PAGE>                           -2-
<PAGE>




   1998,  provided  that for the life of the contract there will always be at
   least a minimum incentive bonus of twenty percent (20%) due in December of
   each year.
   


        4.  DUTIES AND RESPONSIBILITIES

               4.1  Executive shall, during the Term of this Agreement unless
   otherwise  agreed  by management, devote his full attention and expend his
   best  efforts,  energies, and skills on a full-time basis, to the business
   of  the  Company  and  any  corporation controlled by the Company (each, a
   "Subsidiary").    The  Company  acknowledges  that Executive is engaged in
   other  business  activities  separate  from  and  outside the scope of the
   business  of  the  Company.    The  Company  agrees  that  the devotion of
   reasonable  amounts  of  time  to  such other business activities will not
   violate  the  terms  of  this  Agreement  on  the conditions that (i) such
   activities  are  not corporate opportunities of the Company; and (ii) such
   activities  do  not  interfere  with the performance of Executive's duties
   hereunder.    For purposes of this Agreement, the term the "Company" shall
   mean the Company and all Subsidiaries.

             4.2  During the Term of this Agreement, Executive shall serve as
   the  President and Chief Executive Officer of the Company or in such other
   capacities  as  determined  by  the  Board  of  Directors or its Executive
   Committee except as provided for under Subsection 7.1.  In the performance

   all  of  the  Company s policies, rules, and regulations applicable to its
   executive  of comparable status and shall report directly to, and shall be
   subject  to,  the  direction and control of the Executive Committee of the
   Company  and  shall perform such duties as shall be assigned to him by the

   Executive  will  be subject to and abide by, and will use his best efforts
   to cause other employees of the Company to be subject to and abide by, all
   policies  and  procedures  developed  by the Executive Committee or senior
   management of the Company.

             4.3  Without first obtaining the written permission of the Board
   of Directors of the Company, or its Executive Committee, in each instance,
   Executive  will not authorize or permit the Company to engage the services
   of,  or  engage in any business activity with, or provide any financial or
   other  benefit  to,  any affiliate of Executive.  The phrase "affiliate of
   Executive"  as  used  in  this  Subsection  4.3  shall  mean  and  include
   Executive  s  family  by blood or marriage (including, without limitation,
   parents,  spouse,  siblings,  children  and  in-laws), and any business or
   business  entity  which  is  directly or indirectly owned or controlled by
   Executive or any member of Executive s family or in which Executive or any
   member  of  Executive s family has a direct or indirect financial interest
   whatsoever.

                     4.4  To induce the Company to enter into this Agreement,

   of  any  law  or  rule  of law or otherwise which would impair Executive s
   right or ability (a) to enter the employ of the Company, or (b) to perform
   fully his duties and obligations pursuant to this Agreement.


        5.  RESTRICTIVE COVENANTS

                     5.1    Executive  acknowledges  that  (i) he has a major
   responsibility  for  the operation, administration, development and growth
   of  the  Company  s  business,  (ii)  the  Company  s  business has become
   international in scope, (iii) his work for the Company has brought him and
   w i ll  continue  to  bring  him  into  close  contact  with  confidential
   information  of the Company and its customers, and (iv) the agreements and
   covenants  contained  in  this Subsection 5.1 are essential to protect the
   business interests of the Company and that the Company will not enter into
   this  Agreement  but  for  such  agreements  and  covenants.  Accordingly,
   Executive covenants and agrees as follows:

                   5.1.1  Except as otherwise provided for in this Agreement,
   during  the  Term  of  this  Agreement  Executive  shall  not, directly or
   indirectly,  compete  with  respect  to  any  services  or products of the
   Company  which are either offered or are being developed by the Company as
   of  the  date  of  termination; or, without limiting the generality of the
   foregoing,  by  or  become,  or  agree  to  be or become, interested in or
   associated  with,  in  any  capacity  (whether  as a partner, shareholder,
   owner,  officer, director, Executive, principal, agent, creditor, trustee,
   consultant,  co-venturer  or otherwise) any individual, corporation, firm,
   association,  partnership,  joint  venture or other business entity, which
   competes with respect to any services or products of the Company which are
   either  offered  or  are  being developed by the Company as of the date of
   termination;  provided,  however,  that  Executive  may  own, solely as an
   investment,  not  more than one percent (1%) of any class of securities of
   any  publicly  held  corporation  in  competition  with  the Company whose
   securities  are  traded  on any national securities exchange in the United
   States of America.

                   5.1.2  During the Term of this Agreement and, for one year
   thereafter  ("Termination  Period"),  Executive  shall  not,  directly  or
   indirectly,  (i)  induce  or  attempt  to  influence  any Executive of the
   Company  to  leave  its  employ,  (ii) aid or agree to aid any competitor,
   customer  or supplier of the Company in any attempt to hire any person who
   shall  have  been  employed  by the Company within the one (1) year period
   preceding  such requested aid, or (iii) induce or attempt to influence any
   person  or  business  entity who was a customer or supplier of the Company
   during  any  portion of said period to transact business with a competitor
   of the Company in Company s business.

                     5.1.  During the Term of this Agreement, the Termination
   Period and any time thereafter, Executive shall not disclose to anyone any
   information  about the confidential or proprietary affairs of the Company,
   i n c l u ding,  without  limitation,  trade  secrets,  trade  "know-how",
   inventions,  customer  lists, business plans, operational methods, pricing
   p o licies,  marketing  plans,  sales  plans,  identity  of  suppliers  or
   customers,  sales,  profits  or  other  financial  information,  which  is




   <PAGE>                           -4-
<PAGE>




   confidential  to  the  Company  or  is not generally known in the relevant
   trade,  nor  shall  Executive make use of any such information for his own
   benefit.

                  5.2  If Executive breaches Subsection 5.1 (the "Restrictive
   Covenants"),  the  Company  shall  have the following rights and remedies,
   each  of  which shall be enforceable, and each of which is in addition to,
   and not in lieu of, any other rights and remedies available to the Company
   at law or in equity:

                   5.2.1  Executive acknowledges and agrees that in the event
   of  a  violation  or  threatened  violation  of  any  of the provisions of
   Subsection  5.1.1,  the  Company  shall have no adequate remedy at law and
   shall therefore be entitled to enforce each such provision by temporary or
   permanent  injunctive  or  mandatory  relief  obtained  in  any  court  of
   competent  jurisdiction  without the necessity or proving damages, posting
   any  bond or other security, and without prejudice to any other rights and
   remedies which may be available at law or in equity.

            5.3  If any of the Restrictive Covenants, or any part thereof, is
   held  to  be  invalid  or  unenforceable,  the  same  shall not affect the
   remainder  of the covenant or covenants, which shall be given full effect,
   without regard to the invalid or unenforceable portions.  Without limiting
   the  generality  of the foregoing, if any of the Restrictive Covenants, or
   any  part  thereof, is held to be unenforceable because of the duration of
   such  provision or the area covered thereby, the parties hereto agree that
   the  court  making  such  determination shall have the power to reduce the
   duration  and/or  area  of  such  provision and, in its reduced form, such
   provision shall then be enforceable.

             5.4  The parties hereto intend to and hereby confer jurisdiction
   to  enforce  the Restrictive Covenants upon the courts of any jurisdiction
   within the geographical scope of such Restrictive Covenants.  In the event
   that  the  courts of any one or more of such jurisdictions shall hold such
   Restrictive  Covenants  wholly  unenforceable  by reason of the breadth of
   such  scope  or  otherwise, it is the intention of the parties hereto that
   such determination not bar or in any way affect the Company s right of the
   relief  provided above in the courts of any other jurisdictions within the
   geographical  scope  of such Restrictive Covenants, as to breaches of such
   covenants  in  such other respective jurisdictions, the above covenants as
   they  relate  to each jurisdiction being, for this purpose, severable into
   diverse and independent covenants.


        6.  TERMINATION.

                6.1  The basic three-year term shall automatically be renewed
   each  year  on  the anniversary date of this Agreement, unless the Company
   elects  to  terminate  the  Agreement.    Upon  election  to terminate the
   Agreement, the Company may exercise two options.

   by  a  court  of  competent jurisdiction, (ii) commits any act of fraud or
   intentional  misrepresentation,  (iii)  has engaged in serious misconduct,
   which  conduct  has,  or  would,  if generally known, materially adversely

   notice  by  the  Board  to  Executive  regarding such conduct,  (iv) is in
   material breach under this Agreement, or (v) Executive habitually fails to

   Board,  and,  with  regard  to  grounds  (iv)  and (v) the Board has given
   Executive  thirty  (30)  days  written  notice  of  the  grounds  for  the
   termination  and  the  conduct required by Executive to cure such failure,
   with  such conduct outlined with reasonable specificity, and Executive has
   not  cured such failure, within the thirty (30) day period provided in the
   written notice to Executive.

             6.3  If the Company terminates Executive s employment under this
   Agreement  pursuant  to the provisions of Subsections 6.2, Executive shall

   Executive,  the  estate of Executive or the Executive, as the case may be,
   shall continue to receive compensation as determined in Section 7 below.

             6.5  If Executive s employment with the Company is terminated as
   the  result  of Executive s purely voluntary resignation for reasons other
   than  those  set forth in Section 7 below, Executive shall not be entitled
   to compensation after the effective date of such resignation.

        11.  LEGAL DEFENSE.

                     The Company acknowledges that the environmental services
   industry  is  a  highly  litigious industry whereby many regulatory fines,
   penalties  and  third-party suits are directed at the individuals involved
   in  ownership  and  operations.  The Company agrees to pay all legal fees,
   judgments,  awards,  bonds,  fines,  penalties  and  costs  related to the
   defense  and  outcome  whereby  Executive  was  acting  in  his  corporate
   capacity.

   pledged  or  hypothecated  except  as otherwise expressly permitted by the
   provisions of this Agreement.  Executive shall not under any circumstances

   Eighty  Thousand  Dollars ($180,000) per year.  The Company shall pay such
   compensation  to  Executive  semi-monthly  in accordance with its standard
   practice for payment of compensation to its employees.  

                 3.2  Executive shall be entitled to periodic cash bonuses in
   accordance  with the Metalclad Corporation Stock Option and Incentive Plan
   and  the  award of stock options, any other incentive bonus plans or other
   forms  of  compensation,  at  the  discretion  of  the  Company s Board of
   Directors,  dependent  upon  Employee  s  performance.  Executive shall be
   entitled to participate in the Company s 401(k) plan.

            3.3  Executive shall be entitled to a car allowance and to health
   insurance for him and his dependents.

              3.4  All compensation shall be subject to customary withholding
   t a x  and  other  employment  taxes  as  are  required  with  respect  to
   compensation paid by a corporation to an employee.

                3.5  In order to provide proper incentives to those personnel
   engaged  in  developing waste processing facilities in Mexico, the Company
   recognizes  that  it  must  institute special bonus programs and incentive
   bonus  programs  from  time  to  time.    For  the calendar year 1998, the
   Compensation  Committee  has  approved both a special bonus program and an
   incentive bonus program as follows:

                      3.5.1  Special Bonus Program.  Because of the Company s
   involvement  in  a  NAFTA  arbitration  against  the Federal Government of
   Mexico,  it  requires an extraordinary effort on the part of key employees
   to  ensure  the  success  of the litigation on the part of the Company.  A
   total  of  five percent (5%) of the award, or the value of the settlement,
   is  to be shared with three key executives.  The Executive herein shall be
   entitled to one percent (1%) of the total award, or the total value of the
   settlement of the case, in the event there is a settlement.  

                 3.5.2  Incentive Bonus Program.  For the calendar year 1998,
   the  Board  of  Directors  has  set  three  major  objectives  for the key
   executives.  The objectives include opening the Aguascalientes project for
   commercial  operations,  keeping  the  Company  properly  capitalized  for
   growth,  and  respecting the public market participation in the Company to
   ensure  that  gains  made  by  the  Company  are  recognized by its public
   ownership  and  reflected  in  its  share price.  To the extent that these
   objectives  are  met, the key participants in the incentive bonus program,
   including  the  Executive herein, shall be entitled to a minimum of twenty
   percent (20%) of his base salary to a maximum of one hundred fifty percent
   (150%)  of  base salary, depending upon the extent to which the objectives
   have been achieved.

                  It is expected that the foregoing bonuses will be earned in
   1998,  unless  the  settlement or conclusion of the NAFTA litigation takes
   longer,  in  which  case that particular special bonus will go beyond 1998
   until  there  is  a  final  resolution.   It is expected that the Board of
   Directors will provide additional bonus incentives for years subsequent to




   <PAGE>                             -2-
<PAGE>




   1998,  provided  that for the life of the contract there will always be at
   least a minimum incentive bonus of twenty percent (20%) due in December of
   each year.

   

        4.  DUTIES AND RESPONSIBILITIES

               4.1  Executive shall, during the Term of this Agreement unless
   otherwise  agreed  by management, devote his full attention and expend his
   best  efforts,  energies, and skills on a full-time basis, to the business
   of  the  Company  and  any  corporation controlled by the Company (each, a
   "Subsidiary").    The  Company  acknowledges  that Executive is engaged in
   other  business  activities  separate  from  and  outside the scope of the
   business  of  the  Company.    The  Company  agrees  that  the devotion of
   reasonable  amounts  of  time  to  such other business activities will not
   violate  the  terms  of  this  Agreement  on  the conditions that (I) such
   activities  are  not corporate opportunities of the Company; and (ii) such
   activities  do  not  interfere  with the performance of Executive's duties
   hereunder.    For purposes of this Agreement, the term the "Company" shall
   mean the Company and all Subsidiaries.

             4.2  During the Term of this Agreement, Executive shall serve as
   the  Chief Financial Officer of the Company or in such other capacities as
   determined  by the Board of Directors or its Executive Committee except as
   provided  for  under  Subsection  7.1.    In the performance of all of his
   responsibilities  hereunder,  Executive  shall  be  subject  to all of the
   Company  s policies, rules, and regulations applicable to its executive of
   comparable  status  and shall report directly to, and shall be subject to,
   the  direction  and  control of the Executive Committee of the Company and
   shall  perform  such  duties  as  shall be assigned to him by the Board of
   Directors  or  the  Executive  Committee.    In  performing  such  duties,
   Executive  will  be subject to and abide by, and will use his best efforts
   to cause other employees of the Company to be subject to and abide by, all
   policies  and  procedures  developed  by the Executive Committee or senior
   management of the Company.

             4.3  Without first obtaining the written permission of the Board
   of Directors of the Company, or its Executive Committee, in each instance,
   Executive  will not authorize or permit the Company to engage the services
   of,  or  engage in any business activity with, or provide any financial or
   other  benefit  to,  any affiliate of Executive.  The phrase "affiliate of
   Executive"  as  used  in  this  Subsection  4.3  shall  mean  and  include
   Executive  s  family  by blood or marriage (including, without limitation,
   parents,  spouse,  siblings,  children  and  in-laws), and any business or
   business  entity  which  is  directly or indirectly owned or controlled by
   Executive or any member of Executive s family or in which Executive or any
   member  of  Executive s family has a direct or indirect financial interest
   whatsoever.

                     4.4  To induce the Company to enter into this Agreement,
   Executive represents and warrants to the Company that (I) Executive is not
   a  party  or subject to any employment agreement or arrangement with other
   person,   firm,  company,  corporation  or  other  business  entity,  (ii)
   Executive  is subject to no restraint, limitation or restriction by virtue




   <PAGE>                             -3-
<PAGE>




   of  any  law  or  rule  of law or otherwise which would impair Executive s
   right or ability (a) to enter the employ of the Company, or (b) to perform
   fully his duties and obligations pursuant to this Agreement.


       5.  RESTRICTIVE COVENANTS

                     5.1    Executive  acknowledges  that  (I) he has a major
   responsibility  for  the operation, administration, development and growth
   of  the  Company  s  business,  (ii)  the  Company  s  business has become
   international in scope, (iii) his work for the Company has brought him and
   w i ll  continue  to  bring  him  into  close  contact  with  confidential
   information  of the Company and its customers, and (iv) the agreements and
   covenants  contained  in  this Subsection 5.1 are essential to protect the
   business interests of the Company and that the Company will not enter into
   this  Agreement  but  for  such  agreements  and  covenants.  Accordingly,
   Executive covenants and agrees as follows:

                   5.1.1  Except as otherwise provided for in this Agreement,
   during  the  Term  of  this  Agreement  Executive  shall  not, directly or
   indirectly,  compete  with  respect  to  any  services  or products of the
   Company  which are either offered or are being developed by the Company as
   of  the  date  of  termination; or, without limiting the generality of the
   foregoing,  by  or  become,  or  agree  to  be or become, interested in or
   associated  with,  in  any  capacity  (whether  as a partner, shareholder,
   owner,  officer, director, Executive, principal, agent, creditor, trustee,
   consultant,  co-venturer  or otherwise) any individual, corporation, firm,
   association,  partnership,  joint  venture or other business entity, which
   competes with respect to any services or products of the Company which are
   either  offered  or  are  being developed by the Company as of the date of
   termination;  provided,  however,  that  Executive  may  own, solely as an
   investment,  not  more than one percent (1%) of any class of securities of
   any  publicly  held  corporation  in  competition  with  the Company whose
   securities  are  traded  on any national securities exchange in the United
   States of America.

                   5.1.2  During the Term of this Agreement and, for one year
   thereafter  ("Termination  Period"),  Executive  shall  not,  directly  or
   indirectly,  (I)  induce  or  attempt  to  influence  any Executive of the
   Company  to  leave  its  employ,  (ii) aid or agree to aid any competitor,
   customer  or supplier of the Company in any attempt to hire any person who
   shall  have  been  employed  by the Company within the one (1) year period
   preceding  such requested aid, or (iii) induce or attempt to influence any
   person  or  business  entity who was a customer or supplier of the Company
   during  any  portion of said period to transact business with a competitor
   of the Company in Company s business.

                    5.1.3  During the Term of this Agreement, the Termination
   Period and any time thereafter, Executive shall not disclose to anyone any
   information  about the confidential or proprietary affairs of the Company,
   i n c l u ding,  without  limitation,  trade  secrets,  trade  "know-how",
   inventions,  customer  lists, business plans, operational methods, pricing
   p o licies,  marketing  plans,  sales  plans,  identity  of  suppliers  or
   customers,  sales,  profits  or  other  financial  information,  which  is




   <PAGE>                             -4-
<PAGE>




   confidential  to  the  Company  or  is not generally known in the relevant
   trade,  nor  shall  Executive make use of any such information for his own
   benefit.

                  5.2  If Executive breaches Subsection 5.1 (the "Restrictive
   Covenants"),  the  Company  shall  have the following rights and remedies,
   each  of  which shall be enforceable, and each of which is in addition to,
   and not in lieu of, any other rights and remedies available to the Company
   at law or in equity:

                5.2.1  Executive acknowledges and agrees that in the event of
   a violation or threatened violation of any of the provisions of Subsection
   5.1.1,  the  Company  shall  have  no  adequate  remedy  at  law and shall
   therefore  be  entitled  to  enforce  each  such provision by temporary or
   permanent  injunctive  or  mandatory  relief  obtained  in  any  court  of
   competent  jurisdiction  without the necessity or proving damages, posting
   any  bond or other security, and without prejudice to any other rights and
   remedies which may be available at law or in equity.

            5.3  If any of the Restrictive Covenants, or any part thereof, is
   held  to  be  invalid  or  unenforceable,  the  same  shall not affect the
   remainder  of the covenant or covenants, which shall be given full effect,
   without regard to the invalid or unenforceable portions.  Without limiting
   the  generality  of the foregoing, if any of the Restrictive Covenants, or
   any  part  thereof, is held to be unenforceable because of the duration of
   such  provision or the area covered thereby, the parties hereto agree that
   the  court  making  such  determination shall have the power to reduce the
   duration  and/or  area  of  such  provision and, in its reduced form, such
   provision shall then be enforceable.

             5.4  The parties hereto intend to and hereby confer jurisdiction
   to  enforce  the Restrictive Covenants upon the courts of any jurisdiction
   within the geographical scope of such Restrictive Covenants.  In the event
   that  the  courts of any one or more of such jurisdictions shall hold such
   Restrictive  Covenants  wholly  unenforceable  by reason of the breadth of
   such  scope  or  otherwise, it is the intention of the parties hereto that
   such determination not bar or in any way affect the Company s right of the
   relief  provided above in the courts of any other jurisdictions within the
   geographical  scope  of such Restrictive Covenants, as to breaches of such
   covenants  in  such other respective jurisdictions, the above covenants as
   they  relate  to each jurisdiction being, for this purpose, severable into
   diverse and independent covenants.


        6.  TERMINATION.

                6.1  The basic three-year term shall automatically be renewed
   each  year  on  the anniversary date of this Agreement, unless the Company
   elects  to  terminate  the  Agreement.    Upon  election  to terminate the
   Agreement, the Company may exercise two options.

                  (I) It may elect to require the Executive to remain working
   as per his duties and responsibilities outlined in Section 4.

   the  Company and (a) remain as a consultant or (b) sever all relationships

   annual  compensation, including bonus and benefits during the remainder of
   the three-year term.

             6.2  The Company also may terminate Executive s employment under
   this  Agreement  at  any  time  for  Cause.   "Cause" shall exist for such
   termination  if  Executive (I) is adjudicated guilty of illegal activities
   by  a  court  of  competent jurisdiction, (ii) commits any act of fraud or
   intentional  misrepresentation,  (iii)  has engaged in serious misconduct,
   which  conduct  has,  or  would,  if generally known, materially adversely
   affect  the  good  will  or  reputation  of  the Company and which conduct
   Executive  has not cured or altered within ten (10) days following written
   notice  by  the  Board  to  Executive  regarding such conduct,  (iv) is in
   material breach under this Agreement, or (v) Executive habitually fails to
   perform  the duties and responsibilities of his employment as set forth in
   Section 4 of this Agreement or as may be assigned or delegated to him from
   time  to time by the Company, the Board, or the Executive Committee of the
   Board,  and,  with  regard  to  grounds  (iv)  and (v) the Board has given
   Executive  thirty  (30)  days  written  notice  of  the  grounds  for  the
   termination  and  the  conduct required by Executive to cure such failure,
   with  such conduct outlined with reasonable specificity, and Executive has
   not  cured such failure, within the thirty (30) day period provided in the
   written notice to Executive.

             6.3  If the Company terminates Executive s employment under this
   Agreement  pursuant  to the provisions of Subsections 6.2, Executive shall

   finds the he has been properly terminated pursuant to grounds (I) or (ii).

   to  the  death  or  permanent  disability  of Executive, the spouse of the
   Executive,  the  estate of Executive or the Executive, as the case may be,
   shall continue to receive compensation as determined in Section 7 below.

             6.5  If Executive s employment with the Company is terminated as
   the  result  of Executive s purely voluntary resignation for reasons other
   than  those  set forth in Section 7 below, Executive shall not be entitled
   to compensation after the effective date of such resignation.


        7.  TERMINATION COMPENSATION.

               7.1  Compensation as defined in Section 3 above shall continue

   event:  (I) Executive is requested to resign pursuant to Section 6.1; (ii)
   the  death of Executive, said amount being paid to his spouse or estate as
   the  case may be; (iii) inability to discharge his responsibilities due to
   health  or  a  disability  in  which  case,  after  six  months  of such a
   condition, the Board may cancel the contract pursuant to paragraph 6.1; or
   (iv)  the  Executive  resigns  due to a substantial change in ownership or

   duties  and  to  carry  out  and  perform orders, directions, and policies
   stated  by the Board of Directors, to him from time to time, either orally
   or in writing.  Executive understands Company is a subsidiary of Metalclad

   and  life insurance plans of the Company as may be provided by the Company
   from  time to time to Company executives of comparable status, subject to,
   and  to the extent that, Executive is eligible under such benefit plans in
   accordance with their respective terms.


        11.  LEGAL DEFENSE.

                     The Company acknowledges that the environmental services
   industry  is  a  highly  litigious industry whereby many regulatory fines,
   penalties  and  third-party suits are directed at the individuals involved
   in  ownership  and  operations.  The Company agrees to pay all legal fees,
   judgments,  awards,  bonds,  fines,  penalties  and  costs  related to the
   defense  and  outcome  whereby  Executive  was  acting  in  his  corporate
   capacity.


        12.  MISCELLANEOUS.

                 12.1  The Company may, from time to time, apply for and take
   out,  in  its  own  name  and  at its own expense, life, health, accident,
   disability  or  other  insurance upon Executive in any sum or sums that it
   may  deem  necessary to protect its interests, and Executive agrees to aid
   and cooperate in all reasonable respects with the Company in procuring any
   and  all  such  insurance, including without limitation, submitting to the
   usual  and  customary  medical examinations, and by filling out, executing
   and  delivering  such applications and other instruments in writing as may
   be  reasonably  required  by an insurance company or companies to which an
   application  or  applications for such insurance may be made by or for the

              12.2  This Agreement is a personal contract, and the rights and
   interests  of  Executive hereunder may not be sold, transferred, assigned,
   pledged  or  hypothecated  except  as otherwise expressly permitted by the
   provisions of this Agreement.  Executive shall not under any circumstances
   have  any  option  or right to require payment hereunder otherwise than in
   accordance  with the terms hereof.  Except as otherwise expressly provided
   herein,  Executive shall not have any power of anticipation, alienation or
   assignment of payments contemplated hereunder, and all rights and benefits
   of  Executive  shall be for the sole personal benefit of Executive, and no
   other  person  shall  acquire  any  right,  title or interest hereunder by
   reason  of any sale, assignment, transfer, claim or judgment or bankruptcy
   proceedings  against  Executive;  provided,  however, that in the event of
   E x e c utive  s  death,  Executive  s  estate,  legal  representative  or
   beneficiaries  (as the case may be) shall have the right to receive all of
   the benefit that accrued to Executive pursuant to, and in accordance with,
   the terms of this Agreement.

   to  any  successor of substantially all of its business or assets, and any
   such  successor  and  Executive  shall  be  bound by all of the provisions
   hereof.

                              EMPLOYMENT AGREEMENT


          This Agreement is entered into this 1st day of January, 1998 by and
   b e tween  METALCLAD  CORPORATION,  a  Delaware  corporation  (hereinafter
   referred  to  as  the  "Company"), and Javier Guerra Cisneros (hereinafter
   referred to as "Executive") under the following terms and conditions:

                                    RECITALS:

         WHEREAS, the Company and Executive desire to set forth the terms and
   conditions on which (i) the Company shall employ Executive, (ii) Executive
   shall  render  services  to  the  Company,  and  (iii)  the  Company shall
   compensate Executive for such services; and 

             WHEREAS,  in  connection with the employment of Executive by the
   Company,  the  Company  desires  to restrict Executive s rights to compete
   with the business of the Company and its affiliates;

           NOW, THEREFORE, in consideration of the mutual promises, covenants
   and agreements hereinafter set forth, the parties hereto agree as follows:


        1.  EMPLOYMENT.

            The Company hereby employs Executive and Executive hereby accepts
   employment  with the Company upon the terms and conditions hereinafter set
   forth.


        2.  TERM.

            2.1  The term of this Agreement (the "Term") shall be for a three
   year period commencing on the Effective Date (as defined in Subsection 2.3
   below)  of  this  Agreement,  subject, however, to termination as provided
   herein in Sections 6 and 7 below.

               2.2  Each year, prior to the anniversary date, the company and
   executive shall meet to determine any additional compensation, if any, for
   the remaining contract term.

                2.3  The effective date of this Agreement shall be January 1,
   1998 (the "Effective Date").


        3.  COMPENSATION.

            3.1  For all services rendered by Executive under this Agreement,
   the  Company  shall  pay  or  cause one or more of its subsidiaries to pay
<PAGE>




   Executive  during  the  term  hereof  a  salary at the rate of Two Hundred
   Thousand  Dollars  ($200,000) per year, adjusted to pesos each anniversary
   date  of  the  contract,  which  sum  shall  include payment allowable for
   vacation  and  one  month s salary per Mexican law.  The Company shall pay
   such  compensation  to  Executive  semi-monthly  in  accordance  with  its
   standard practice for payment of compensation to its employees.  

                 3.2  Executive shall be entitled to periodic cash bonuses in
   accordance  with the Metalclad Corporation Stock Option and Incentive Plan
   and  the  award of stock options, any other incentive bonus plans or other
   forms  of  compensation,  at  the  discretion  of  the  Company s Board of
   Directors,  dependent  upon  Employee  s  performance.  Executive shall be
   entitled to participate in the Company s 401(k) plan.

               3.3  Executive shall be entitled to the use of a company-owned
   car and health insurance for him and his dependents.  

              3.4  All compensation shall be subject to customary withholding
   t a x  and  other  employment  taxes  as  are  required  with  respect  to
   compensation paid by a corporation to an employee.

                3.5  In order to provide proper incentives to those personnel
   engaged  in  developing waste processing facilities in Mexico, the Company
   recognizes  that  it  must  institute special bonus programs and incentive
   bonus  programs  from  time  to  time.    For  the calendar year 1998, the
   Compensation  Committee  has  approved both a special bonus program and an
   incentive bonus program as follows:

                      3.5.1  Special Bonus Program.  Because of the Company s
   involvement  in  a  NAFTA  arbitration  against  the Federal Government of
   Mexico,  it  requires an extraordinary effort on the part of key employees
   to  ensure  the  success  of the litigation on the part of the Company.  A
   total  of  five percent (5%) of the award, or the value of the settlement,
   is  to be shared with three key executives.  The Executive herein shall be
   entitled  to  one  and  seventy-five  100ths  percent (1.75%) of the total
   award,  or  the  total  value  of the settlement of the case, in the event
   there is a settlement.  

                 3.5.2  Incentive Bonus Program.  For the calendar year 1998,
   the  Board  of  Directors  has  set  three  major  objectives  for the key
   executives.  The objectives include opening the Aguascalientes project for
   commercial  operations,  keeping  the  Company  properly  capitalized  for
   growth,  and  respecting the public market participation in the Company to
   ensure  that  gains  made  by  the  Company  are  recognized by its public
   ownership  and  reflected  in  its  share price.  To the extent that these
   objectives  are  met, the key participants in the incentive bonus program,
   including  the  Executive herein, shall be entitled to a minimum of twenty
   percent (20%) of his base salary to a maximum of one hundred fifty percent
   (150%)  of  base salary, depending upon the extent to which the objectives
   have been achieved.

                  It is expected that the foregoing bonuses will be earned in
   1998,  unless  the  settlement or conclusion of the NAFTA litigation takes
   longer,  in  which  case that particular special bonus will go beyond 1998




   <PAGE>                           -2-
<PAGE>




   until  there  is  a  final  resolution.   It is expected that the Board of
   Directors will provide additional bonus incentives for years subsequent to
   1998,  provided  that for the life of the contract there will always be at
   least a minimum incentive bonus of twenty percent (20%) due in December of
   each year.


        4.  DUTIES AND RESPONSIBILITIES

               4.1  Executive shall, during the Term of this Agreement unless
   otherwise  agreed  by management, devote his full attention and expend his
   best  efforts,  energies, and skills on a full-time basis, to the business
   of  the  Company  and  any  corporation controlled by the Company (each, a
   "Subsidiary").    For  purposes  of this Agreement, the term the "Company"
   shall mean the Company and all Subsidiaries.

             4.2  During the Term of this Agreement, Executive shall serve as
   the  Director General of Mexican operations or in such other capacities as
   determined  by  the  Board  of  Directors,  except  as  provided for under
   Subsection  7.1.    In  the  performance  of  all  of his responsibilities
   hereunder,  Executive  shall  be subject to all of the Company s policies,
   rules,  and  regulations  applicable to its executive of comparable status
   and  shall  report directly to, and shall be subject to, the direction and
   control  of  the  Board of Directors of the Company and shall perform such
   duties  as  shall  be  assigned  to  him  by  the  Board of Directors.  In
   performing  such  duties,  Executive  will be subject to and abide by, and
   will  use  his  best efforts to cause other employees of the Company to be
   subject  to  and  abide  by,  all policies and procedures developed by the
   Board of Directors or senior management of the Company.

             4.3  Without first obtaining the written permission of the Board
   of  Directors  of  the Company, Executive will not authorize or permit the
   Company  to  engage  the  services  of, or engage in any business activity
   with,  or  provide  any  financial  or  other benefit to, any affiliate of
   Executive.  The phrase "affiliate of Executive" as used in this Subsection
   4.3  shall  mean  and  include  Executive  s  family  by blood or marriage
   (including,  without  limitation,  parents, spouse, siblings, children and
   in-laws),  and  any  business  or  business  entity  which  is directly or
   indirectly  owned  or controlled by Executive or any member of Executive s
   family  or  in  which  Executive or any member of Executive s family has a
   direct or indirect financial interest whatsoever.

                     4.4  To induce the Company to enter into this Agreement,
   Executive represents and warrants to the Company that (i) Executive is not
   a  party  or subject to any employment agreement or arrangement with other
   person,   firm,  company,  corporation  or  other  business  entity,  (ii)
   Executive  is subject to no restraint, limitation or restriction by virtue
   of  any  law  or  rule  of law or otherwise which would impair Executive s
   right or ability (a) to enter the employ of the Company, or (b) to perform
   fully his duties and obligations pursuant to this Agreement.


        5.  RESTRICTIVE COVENANTS





   <PAGE>                           -3-
<PAGE>




                     5.1    Executive  acknowledges  that  (i) he has a major
   responsibility  for  the operation, administration, development and growth
   of  the  Company  s  business,  (ii)  the  Company  s  business has become
   international in scope, (iii) his work for the Company has brought him and
   w i ll  continue  to  bring  him  into  close  contact  with  confidential
   information  of the Company and its customers, and (iv) the agreements and
   covenants  contained  in  this Subsection 5.1 are essential to protect the
   business  interests of the Company and its affiliates and that the Company
   will  not enter into this Agreement but for such agreements and covenants.
   Accordingly, Executive covenants and agrees as follows with respect to the
   Company (which includes all affiliates in Mexico):

                   5.1.1  Except as otherwise provided for in this Agreement,
   during  the  Term  of  this  Agreement  Executive  shall  not, directly or
   indirectly,  compete  with  respect  to  any  services  or products of the
   Company  which are either offered or are being developed by the Company as
   of  the  date  of  termination; or, without limiting the generality of the
   foregoing,  by  or  become,  or  agree  to  be or become, interested in or
   associated  with,  in  any  capacity  (whether  as a partner, shareholder,
   owner,  officer, director, Executive, principal, agent, creditor, trustee,
   consultant,  co-venturer  or otherwise) any individual, corporation, firm,
   association,  partnership,  joint  venture or other business entity, which
   competes with respect to any services or products of the Company which are
   either  offered  or  are  being developed by the Company as of the date of
   termination;  provided,  however,  that  Executive  may  own, solely as an
   investment,  not  more than one percent (1%) of any class of securities of
   any  publicly  held  corporation  in  competition  with  the Company whose
   securities  are  traded  on any national securities exchange in the United
   States of America.

                   5.1.2  During the Term of this Agreement and, for one year
   thereafter  ("Termination  Period"),  Executive  shall  not,  directly  or
   indirectly,  (i)  induce  or  attempt  to  influence  any Executive of the
   Company  to  leave  its  employ,  (ii) aid or agree to aid any competitor,
   customer  or supplier of the Company in any attempt to hire any person who
   shall  have  been  employed  by the Company within the one (1) year period
   preceding  such requested aid, or (iii) induce or attempt to influence any
   person  or  business  entity who was a customer or supplier of the Company
   during  any  portion of said period to transact business with a competitor
   of the Company in Company s business.

                    5.1.3  During the Term of this Agreement, the Termination
   Period and any time thereafter, Executive shall not disclose to anyone any
   information  about the confidential or proprietary affairs of the Company,
   i n c l u ding,  without  limitation,  trade  secrets,  trade  "know-how",
   inventions,  customer  lists, business plans, operational methods, pricing
   p o licies,  marketing  plans,  sales  plans,  identity  of  suppliers  or
   customers,  sales,  profits  or  other  financial  information,  which  is
   confidential  to  the  Company  or  is not generally known in the relevant
   trade,  nor  shall  Executive make use of any such information for his own
   benefit.

                  5.2  If Executive breaches Subsection 5.1 (the "Restrictive
   Covenants"),  the  Company  shall  have the following rights and remedies,




   <PAGE>                           -4-
<PAGE>




   each  of  which shall be enforceable, and each of which is in addition to,
   and not in lieu of, any other rights and remedies available to the Company
   at law or in equity:

                   5.2.1  Executive acknowledges and agrees that in the event
   of  a  violation  or  threatened  violation  of  any  of the provisions of
   Subsection  5.1.1,  the  Company  shall have no adequate remedy at law and
   shall therefore be entitled to enforce each such provision by temporary or
   permanent  injunctive  or  mandatory  relief  obtained  in  any  court  of
   competent  jurisdiction  without the necessity or proving damages, posting
   any  bond or other security, and without prejudice to any other rights and
   remedies which may be available at law or in equity.

            5.3  If any of the Restrictive Covenants, or any part thereof, is
   held  to  be  invalid  or  unenforceable,  the  same  shall not affect the
   remainder  of the covenant or covenants, which shall be given full effect,
   without regard to the invalid or unenforceable portions.  Without limiting
   the  generality  of the foregoing, if any of the Restrictive Covenants, or
   any  part  thereof, is held to be unenforceable because of the duration of
   such  provision or the area covered thereby, the parties hereto agree that
   the  court  making  such  determination shall have the power to reduce the
   duration  and/or  area  of  such  provision and, in its reduced form, such
   provision shall then be enforceable.

             5.4  The parties hereto intend to and hereby confer jurisdiction
   to  enforce  the Restrictive Covenants upon the courts of any jurisdiction
   within the geographical scope of such Restrictive Covenants.  In the event
   that  the  courts of any one or more of such jurisdictions shall hold such
   Restrictive  Covenants  wholly  unenforceable  by reason of the breadth of
   such  scope  or  otherwise, it is the intention of the parties hereto that
   such determination not bar or in any way affect the Company s right of the
   relief  provided above in the courts of any other jurisdictions within the
   geographical  scope  of such Restrictive Covenants, as to breaches of such
   covenants  in  such other respective jurisdictions, the above covenants as
   they  relate  to each jurisdiction being, for this purpose, severable into
   diverse and independent covenants.


        6.  TERMINATION.

                6.1  The basic three-year term shall automatically be renewed
   each  year  on  the anniversary date of this Agreement, unless the Company
   elects  to  terminate  the  Agreement.    Upon  election  to terminate the
   Agreement, the Company may exercise two options.

                 (i)  It may elect to require the Executive to remain working
   as per his duties and responsibilities outlined in Section 4.

                 (ii)  It may ask Executive to leave the day-to-day employ of
   the  Company and (a) remain as a consultant or (b) sever all relationships
   with the Company whatsoever.

                       In either case, the Executive shall be entitled to his
   annual  compensation, including bonus and benefits during the remainder of




   <PAGE>                           -5-
<PAGE>




   the three-year term.

             6.2  The Company also may terminate Executive s employment under
   this  Agreement  at  any  time  for  Cause.   "Cause" shall exist for such
   termination  if  Executive (i) is adjudicated guilty of illegal activities
   by  a  court  of  competent jurisdiction, (ii) commits any act of fraud or
   intentional  misrepresentation,  (iii)  has engaged in serious misconduct,
   which  conduct  has,  or  would,  if generally known, materially adversely
   affect  the  good  will  or  reputation  of  the Company and which conduct
   Executive  has not cured or altered within ten (10) days following written
   notice  by  the  Board  to  Executive  regarding such conduct,  (iv) is in
   material breach under this Agreement, or (v) Executive habitually fails to
   perform  the duties and responsibilities of his employment as set forth in
   Section 4 of this Agreement or as may be assigned or delegated to him from
   time  to time by the Company, the Board, or the Executive Committee of the
   Board,  and,  with  regard  to  grounds  (iv)  and (v) the Board has given
   Executive  thirty  (30)  days  written  notice  of  the  grounds  for  the
   termination  and  the  conduct required by Executive to cure such failure,
   with  such conduct outlined with reasonable specificity, and Executive has
   not  cured such failure, within the thirty (30) day period provided in the
   written notice to Executive.

             6.3  If the Company terminates Executive s employment under this
   Agreement  pursuant  to the provisions of Subsections 6.2, Executive shall
   be entitled to receive only six months severance pay unless the arbitrator
   finds the he has been properly terminated pursuant to grounds (i) or (ii).

            6.4  If Executive s employment with the Company is terminated due
   to  the  death  or  permanent  disability  of Executive, the spouse of the
   Executive,  the  estate of Executive or the Executive, as the case may be,
   shall continue to receive compensation as determined in Section 7 below.

             6.5  If Executive s employment with the Company is terminated as
   the  result  of Executive s purely voluntary resignation for reasons other
   than  those  set forth in Section 7 below, Executive shall not be entitled
   to compensation after the effective date of such resignation.


        7.  TERMINATION COMPENSATION.

               7.1  Compensation as defined in Section 3 above shall continue
   for  a  period of three (3) years following the date of termination in the
   event:  (i) Executive is requested to resign pursuant to Section 6.1; (ii)
   the  death of Executive, said amount being paid to his spouse or estate as
   the  case may be; (iii) inability to discharge his responsibilities due to
   health  or  a  disability  in  which  case,  after  six  months  of such a
   condition, the Board may cancel the contract pursuant to paragraph 6.1; or
   (iv)  the  Executive  resigns  due to a substantial change in ownership or
   Board membership as defined below.

             7.2  A substantial change in ownership shall mean:  (i) the sale

<PAGE>




            7.3  In the event Executive is requested to resign, employment is
   terminated  for  any  reason  by  the Company, including termination under
   Sections  6  or  in the event Executive voluntarily resigns as a result of

   events, all of the Executive s rights under the Company s Stock Option and
   Incentive  Plan  and  all  other  incentive  bonus  plans  shall fully and
   completely vest upon the date of such termination.


        8.  EXPENSES.

   days after submission by Executive of his expense report.


        9.  THE COMPANY S AUTHORITY.

   and  regulations  of  the  Company  as  adopted  by the Company s Board of
   Directors,  either  orally  or  in writing, respecting performances of his
   duties  and  to  carry  out  and  perform orders, directions, and policies
   stated  by the Board of Directors, to him from time to time, either orally
   or in writing.  Executive understands Company is a subsidiary of Metalclad
   Corporation, a Delaware Corporation that operates with both a Board and an
   Executive Committee.  Direction by such Board or Executive Committee shall
   constitute action by the Company s Board and be given the same respect and
   weight.

               10.1  Executive shall be entitled to a paid vacation each year

   policy relating to paid holidays.

              10.2  Executive shall be entitled to reasonable periods of paid
   sick  leave  during  the  Term  of  the  Agreement  in accordance with the
   Company s policy regarding such sick leave.

                  10.3  The Company shall provide Executive, at the Company s
   expense,  participation  in  group medical, accident and health insurance,
   and  life insurance plans of the Company as may be provided by the Company
   from  time to time to Company executives of comparable status, subject to,
   and  to the extent that, Executive is eligible under such benefit plans in
   accordance with their respective terms.

<PAGE>




        11.  LEGAL DEFENSE.

                     The Company acknowledges that the environmental services
   industry  is  a  highly  litigious industry whereby many regulatory fines,
   penalties  and  third-party suits are directed at the individuals involved
   in  ownership  and  operations.  The Company agrees to pay all legal fees,
   judgments,  awards,  bonds,  fines,  penalties  and  costs  related to the
   defense  and  outcome  whereby  Executive  was  acting  in  his  corporate
   capacity.


        12.  MISCELLANEOUS.

            12.1  The Company may, from time to time, apply for and take out,
   in its own name and at its own expense, life, health, accident, disability
   or  other  insurance  upon  Executive  in any sum or sums that it may deem
   necessary  to  protect  its  interests,  and  Executive  agrees to aid and
   cooperate in all reasonable respects with the Company in procuring any and
   all  such insurance, including without limitation, submitting to the usual
   and  customary  medical  examinations,  and  by filling out, executing and
   delivering  such  applications  and other instruments in writing as may be
   reasonably  required  by  an  insurance  company  or companies to which an
   application  or  applications for such insurance may be made by or for the
   Company.  

              12.2  This Agreement is a personal contract, and the rights and
   interests  of  Executive hereunder may not be sold, transferred, assigned,
   pledged  or  hypothecated  except  as otherwise expressly permitted by the
   provisions of this Agreement.  Executive shall not under any circumstances
   have  any  option  or right to require payment hereunder otherwise than in
   accordance  with the terms hereof.  Except as otherwise expressly provided
   herein,  Executive shall not have any power of anticipation, alienation or
   assignment of payments contemplated hereunder, and all rights and benefits

   the Notes in whole but not in part by (A) paying to each Noteholder the
   Discounted Present Value of his Note calculated to the date of such
   prepayment, and (B) issuing to each Noteholder 1,000 Warrants for each
   $1,000.00 of the Purchase Price of his Note (unless such Noteholders shall
   have previously received such amount of Warrants).

           2.6  Upon the occurrence of an Event of Default and so long as the

   the occurrence of such Event of Default and, (i) thereafter, such
   Discounted Present Value of the Note shall bear interest at the Default
   Rate until all amounts due such Noteholder are paid in full, and (ii)

   (the "Warrants") to purchase from Metalclad Corporation, a Delaware
   corporation (the "Company"), at any time or from time to time until 5:00

   subject to the conditions as set forth herein, at the initial exercise
   price of $1.50 per share (the "Initial Exercise Price"), subject to
   adjustment as set forth herein (the "Exercise Price") up to an aggregate
   of ________ shares, subject to adjustment as set forth herein (the
   "Shares"), of fully paid and non-assessable common stock, $.10 par value
   (the "Common Stock"), of the Company upon surrender of this Certificate
   and payment of the Exercise Price at the principal office of the Company
   presently located at 2 Corporate Plaza, Suite 125, Newport Beach,
   California 92660, United States. The number of Shares purchaseable upon

   to adjustment from time to time as set forth herein. The exercise of the

   The exercise of the Warrants is subject to compliance with the conditions
   set forth herein under the heading "Compliance with U.S. Securities Laws."
   under the heading "Compliance with U.S. Securities Laws."

        1.  Exercise of Warrants.




   <PAGE>                             1
<PAGE>







           (a)  The exercise of any Warrants represented by this Certificate
   is subject to the conditions set forth below in "Compliance with U.S.
   Securities Laws."

           (b)  Subject to compliance with the conditions set forth below in
   "Compliance with U.S. Securities Laws," the Holder shall have the right to
   purchase from the Company the number of Shares which the Holder may at the
   time be entitled to purchase pursuant hereto, upon surrender to the
   Company at its principal office, of this Certificate together with the
   form of election to purchase attached hereto duly completed and signed,
   and upon payment to the Company of the aggregate Exercise Price for the
   number of Shares in respect of which Warrants are then exercised.

            (c)  No Warrant may be exercised after 5:00 p.m., California
   time, on the Expiration Date, at which time all Warrants evidenced hereby,
   unless exercised prior thereto, shall thereafter be void.

            (d)  Payment of the aggregate Exercise Price for the number of
   Shares in respect of which Warrants are exercised shall be made in cash,
   or by certified check or bank draft payable to the order of the Company,
   or any combination of the foregoing.

            (e)  The Warrants represented by this Certificate are exercisable
   at the option of the Holder, in whole or in part (but not as to fractional
   shares of Common Stock). Upon the exercise of less than all of the
   Warrants evidenced by this Certificate, the Company shall forthwith issue
   to the Holder a new Certificate of like tenor representing such number of
   unexercised Warrants.

            (f)  Upon surrender of this Certificate and payment of the
   Exercise Price as aforesaid, the Company shall cause to be delivered with
   all reasonable dispatch to or upon the written order of the Holder and in
   such name or names as the Holder may designate, a certificate or
   certificates for the number of whole Shares purchased upon the exercise of
   the Warrants.

        2.  Elimination of Fractional Interests. The Company shall not be
   required to issue certificates representing fractions of shares of Common
   Stock and shall not be required to issue scrip or pay cash in lieu of
   fractional interests, it being the intent of the parties that all
   fractional interests shall be eliminated by rounding any fraction up to
   the nearest whole number of shares of Common Stock.

        3.  Payment of Taxes. The Company will pay all documentary stamp
   taxes, if any, attributable to the issuance and delivery of the Shares
   upon the exercise of the Warrants; provided, however, that the Company
   shall not be required to pay any tax or taxes which may be payable in
   respect of any transfer involved in the issuance or delivery of any
   Warrant or the delivery of any Shares in any name other than that of the
   Holder, which transfer taxes shall be paid by the Holder.





   <PAGE>                             2
<PAGE>






        4.  Compliance with U.S. Securities Laws. The Warrants and the shares
   of Common Stock issuable upon the exercise of the Warrants have not been
   and will not be registered under the United States Securities Act of 1933,
   as amended (the "Act"), and the Warrants may not be exercised within the
   United States or by or on behalf of any "U.S. person" (as defined in
   Regulation S under the Act) unless the Warrants and such shares of Common
   Stock are registered under the Act or an exemption from such registration
   is available. Accordingly, it is a condition to the exercise of the
   Warrants that (I) any shares of Common Stock issuable upon such exercise
   will not be delivered within the United States except in circumstances
   constituting an "offshore transaction" (as defined in Regulation S under
   the Act) or unless such shares have been registered under the Act or an
   exemption from such registration is available, and (ii) the exercising
   Holder must deliver to the Company (A) a written certification that such
   Holder is not a "U.S. person" (as defined in Regulation S under the Act)
   and that the Warrants are not being exercised on behalf of, or for the
   account or benefit of, a "U.S. person" (as defined in Regulation S under
   the Act), or (B) a written opinion of United States counsel, in form and
   substance satisfactory to the Company, to the effect that the Warrants and
   the shares of Common Stock issuable upon exercise thereof have been
   registered under the Act or are exempt from registration under the Act.

        5.  Transfer of Warrants. The Warrants shall be transferable only on
   the books of the Company maintained at the Company s principal office upon
   delivery of this Certificate with the form of assignment attached hereto
   duly completed and signed by the Holder or by its duly authorized attorney
   or representative, or accompanied by proper evidence of succession,
   assignment or authority to transfer. The Company may, in its discretion,
   require, as a condition to any transfer of Warrants, a signature guarantee
   by a commercial bank or trust company, by a broker or dealer which is a
   member of the National Association of Securities Dealers, Inc., or by a
   member of a national securities exchange, The Securities and Futures
   Authority Limited in the United Kingdom, or The International Stock
   Exchange in London, England. Upon any registration of transfer, the
   Company shall deliver a new certificate or certificates of like tenor and
   evidencing in the aggregate a like number of Warrants to the person
   entitled thereto in exchange for this Certificate, subject to the
   limitations provided herein, without any charge except for any tax, or
   other governmental charge imposed in connection therewith.

        6.  Exchange and Replacement of Warrant Certificates; Loss of
   Mutilated Warrant Certificates.

            (a)  This Certificate is exchangeable without expense, upon the
   surrender hereof by the Holder at the principal office of the Company, for
   a new Certificate of like tenor and date representing in the aggregate the
   right to purchase the same number of Shares in such denominations as shall
   be designated by the Holder at the time of such surrender.

            (b)  Upon receipt by the Company of evidence reasonably
   satisfactory to it of the loss, theft, destruction or mutilation of any
   Certificate and, in case of such loss, theft or destruction, of indemnity




   <PAGE>                             3
<PAGE>






   or security reasonably satisfactory to it, and reimbursement to the
   Company of all reasonable expenses incidental thereto, and upon surrender
   and cancellation of the Certificate, if mutilated, the Company will make
   and deliver a new Certificate of like tenor, in lieu thereof.

        7.  Initial Exercise Price; Adjustment of Exercise Price.

            (a)  Initial Exercise Price. The Warrants initially are
   exercisable at the Initial Exercise Price per Share, subject to adjustment
   from time to time as provided herein.

            (b)  Computation of Adjusted Price. Subject to the exceptions
   referred to in paragraph (g) below, in the event that the Company shall at
   any time after the initial issuance date of the Warrants represented by
   this Certificate issue or sell any shares of Common Stock (other than the
   issuance or sale of Common Stock referred to in paragraph (g) below),
   including shares of Common Stock held in the Company s treasury, for a
   consideration per share less than the Exercise Price in effect immediately
   prior to the issuance or sale of such shares or less than the Market Price
   (as defined in subparagraph (vi) below), or without consideration, then
   forthwith upon such issuance or sale, the Exercise Price shall (until
   another such issuance or sale) be reduced to a price (calculated to the
   nearest full cent) equal to the quotient derived by dividing (I) an amount
   equal to the sum of (A) the product of (x) the total number of shares of
   Common Stock outstanding immediately prior to such issuance or sale,
   multiplied by (y) the lower of (1) the Exercise Price in effect
   immediately prior to such issuance or sale or (2) the Market Price per
   share of Common Stock on the date immediately prior to the issuance or
   sale of such shares, plus, (B) the aggregate of the amount of all
   consideration, if any, received by the Company upon such issuance or sale,
   by (ii) the total number of shares of Common Stock outstanding immediately
   after such issuance or sale; provided however, that in no event shall the
   Exercise Price be adjusted pursuant to this computation to an amount in
   excess of the Exercise Price in effect immediately prior to such
   computation, except in the case of readjustments provided for in paragraph
   (c) below or a combination of outstanding shares of Common Stock provided
   in paragraph (d) below.

        For the purposes of any computation to be made in accordance with
   this paragraph (b), the following provisions shall be applicable:

                (i)  In case of the issuance or sale of shares of Common
   Stock for a consideration part or all of which shall be cash, the amount
   of the cash consideration therefor shall be deemed to be the amount of
   cash received by the Company for such shares (or, if shares of Common
   stock are offered by the Company for subscription, the subscription price,
   or, if such shares of Common Stock shall be sold to underwriters or
   dealers for public offering without a subscription offering, the initial
   public offering price) before deducting therefrom any compensation paid or
   discount allowed in the sale, underwriting or purchase thereof by
   underwriters or dealers or others performing similar services, or any
   expenses incurred in connection therewith.




   <PAGE>                             4
<PAGE>






                (ii)  In case of the issuance or sale (otherwise than as a
   dividend or other distribution on any stock of the Company, or on the
   exercise of options, rights or warrants or on the conversion or exchange
   of convertible or exchangeable securities) of shares of Common Stock for a
   consideration part or all of which shall be other than cash, the amount of
   the consideration therefor other than cash shall be deemed to be the value
   of such consideration as determined in good faith by the Board of
   Directors of the Company of Common Stock issuable by way of dividend or
   other distribution on any stock of the Company shall be deemed to have
   been issued immediately after the opening of business on the day following
   the record date for the determination of stockholders entitled to receive
   such dividend or other distribution and shall be deemed to have been
   issued without consideration.

                (iii)  Shares of Common Stock issuable by way of dividend or
   other distribution on any stock of the Company shall be deemed to have
   been issued immediately after the opening of business on the day following
   the record date for the determination of stockholders entitled to receive
   such dividend or other distribution and shall be deemed to have been
   issued without consideration.

                (iv)  The reclassification of securities of the Company
   (other than shares of Common Stock into securities including shares of
   Common Stock) shall be deemed to involve the issuance of such shares of
   Common Stock for a consideration other than cash immediately prior to the
   close of business on the date fixed for the determination of security
   holders entitled to receive such shares, and the value of the
   consideration allocable to such shares of Common Stock shall be determined
   as provided in subparagraph (ii) above.

                (v)  The number of Shares of Common Stock at any one time
   outstanding shall include the aggregate number of shares issued or
   issuable (subject to readjustment upon the actual issuance thereof) upon
   the exercise of options, rights, warrants and upon the conversion or
   exchange of convertible or exchangeable securities.

                (vi)  As used herein, the phrase "Market Price" at any date
   shall be deemed to be the average of the last reported sale price, or, in
   case no such reported sale takes place on such day, the average of the
   last reported sale prices for the last three trading days, in either case
   as officially reported by the principal securities exchange on which the
   common stock is listed or admitted to trading or as reported in the
   Automated Quotation System of the  National Association of Securities
   Dealers, Inc. (the "Nasdaq System"), or, if the Common Stock is not listed
   or admitted to trading on any national securities exchange or quoted on
   the Nasdaq System, the closing bid price as furnished by the National
   Association of Securities Dealers, Inc. through Nasdaq or similar
   organization if Nasdaq is no longer reporting such information, or, if the

   after such issuance or sale.

            (c)  Options. Rights. Warrants and Convertible and Exchangeable
   Securities. Except in the case of the Company issuing rights to subscribe
   for shares of Common Stock distributed to all the stockholders of the
   Company and Holders of Warrants pursuant to paragraph (i), in the event
   that the Company shall at any time after December 31, 1997 issue any
   options, rights or warrants to subscribe for shares of Common Stock, or
   issue any securities convertible into or exchangeable for shares of Common
   Stock (other than the issuance or exercise of options, rights or warrants
   referred to in paragraph (g) below), (i) for a consideration per share
   less than (A) the Exercise Price in effect immediately prior to the
   issuance of such options, rights, or warrants, or such convertible or
   exchangeable securities, or (B) the Market Price, or (ii) without
   consideration, the Exercise Price in effect immediately prior to the
   issuance of such options, rights or warrants, or such convertible or
   exchangeable securities, as the case may be, shall be reduced to a price
   determined by making a computation in accordance with the provisions of
   paragraph (b) above; provided, however, that:

                (i)  The aggregate maximum number of shares of Common Stock
   issuable under such options, rights or warrants shall be deemed to be
   issued and outstanding at the time such options, rights or warrants are
   issued, and for a consideration equal to the minimum purchase price per
   share of Common Stock provided for in such options, rights or warrants at
   the time or issuance, plus the consideration (determined in the same
   manner as consideration received on the issue or sale of shares of Common
   Stock), if any, received by the Company for such options, rights or
   warrants, and if no minimum price is provided in such options, rights or
   warrants, then the consideration shall be equal to zero; provided herein,
   that upon the expiration or other termination of such options, rights or
   warrants, if any thereof shall not have been exercised, the number of
   shares of Common Stock deemed to be issued and outstanding pursuant to
   this subparagraph (i) (and for the purposes of subparagraph (v) of
   paragraph (b) above) shall be reduced by such number of shares of Common
   Stock as to which options, warrants and/or rights shall have expired or
   terminated unexercised, and such number of shares of Common Stock shall no
   longer be deemed to be issued and outstanding, and the Exercise Price then
   in effect shall forthwith be readjusted and thereafter be the price which
   it would have been had adjustment been made on the basis of the issuance
   only of shares of Common Stock actually issued or issuable upon the
   exercise of those options, rights or warrants as to which the exercise
   rights shall not have expired or terminated unexercised.

                (ii)  The aggregate maximum number of shares of Common Stock
   issuable upon conversion or exchange of any convertible or exchangeable
   securities shall be deemed to be issued and outstanding at the time of
   issuance of such securities, and for a consideration equal to the
   consideration (determined in the same manner as consideration received on
   the issue or sale of shares of Common Stock) received by the Company for
   such securities, plus the minimum consideration, if any, receivable by the
   Company upon the conversion or exchange thereof; provided, however, that




   <PAGE>                             6
<PAGE>






   upon the termination of the right to convert or exchange such convertible
   or exchangeable securities (whether by reason of redemption or otherwise),
   the number of shares of Common Stock deemed to be issued and outstanding
   pursuant to this subparagraph (ii) (and for the purpose of subparagraph
   (v) of paragraph (b) above) shall be reduced by such number of shares of
   Common Stock as to which the conversion or exchange rights shall have
   expired or terminated unexercised, and such number of shares shall no
   longer be deemed to be issued and outstanding and the Exercise Price then
   in effect shall forthwith be readjusted and thereafter be the price which
   it would have been had adjustment been made on the basis of the issuance
   only of the shares of Common Stock actually issued or issuable upon the
   conversion or exchange of those convertible or exchangeable securities as
   to which the conversion or exchange rights shall not have expired or
   terminated unexercised.

                (iii)  If any change shall occur in the price per share
   provided for in any of the options, rights or warrants referred to in
   subparagraph (i) above, or in the price per share at which the securities
   referred to in subparagraph (ii) above are convertible or exchangeable,
   such options, rights or warrants or conversion or exchange rights, as the
   case may be, shall be deemed to have expired or terminated on the date
   when such price change became effective in respect of shares not
   theretofore issued pursuant to the exercise or conversion or exchange
   thereof, and the Company shall be deemed to have issued upon such date new
   options, rights or warrants or convertible or exchangeable securities at
   the new price in respect of the number of shares issuable upon the
   exercise of such options, rights or warrants or the conversion or exchange
   of such convertible or exchangeable securities.

                (iv)  When an adjustment has been made in the Exercise Price
   pursuant to this paragraph (c) in respect of the issuance of any options,
   rights or warrants to subscribe for shares of Common Stock or the issuance
   of any securities convertible into or exchangeable for shares of Common
   Stock, no additional adjustment in the Exercise Price shall be made
   pursuant to paragraph 7(b) above upon the issuance of shares of Common
   Stock upon the exercise of such options, rights or warrants or upon the
   conversion or exchange of such securities.

            (d)  Subdivision and Combination. In the event that the Company
   shall at any time subdivide or combine the outstanding shares of Common
   Stock, the Exercise Price shall forthwith be proportionately decreased in
   the case of subdivision or increased in the case of combination.

            (e)  Reclassification. Consolidation. Merger. Etc.. In the event
   of any reclassification or change of the outstanding shares of Common
   Stock (other than a change in par value to no par value, or from no par
   value to par value, or as a result of a subdivision or combination), or in
   the event of any consolidation of the Company with, or merger of the
   Company into, another corporation (other than a consolidation or merger in
   which the Company is the surviving corporation and which does not result
   in any reclassification or change of the outstanding shares of Common
   Stock, except a change as a result of a subdivision or combination of such




   <PAGE>                             7
<PAGE>






   shares or a change in par value, as aforesaid), or in the case of a sale
   or conveyance to another corporation of the property of the Company as an
   entirety or substantially as an entirety, the Holder shall thereafter have
   the right to convert into and to purchase the kind and respective number
   of shares of stock and other securities and property receivable upon such
   reclassification, change, consolidation, merger, sale or conveyance as if
   the Holder were the owner of the shares of Common Stock underlying the
   Warrants immediately prior to any such events at a price equal to the
   product of (x) the number of shares issuable upon exercise of the Warrants
   and (y) the Exercise Price in effect immediately prior to the record date
   for such reclassification, change, consolidation, merger, sale or
   conveyance as if such Holder had exercised the Warrants.

            (f)  No Adjustment of Exercise Price in Certain Cases. No
   adjustment of the Exercise Price shall be made:

                (i) upon the issuance or sale of shares of Common Stock upon
   the exercise of the Warrants; or

                (ii) upon the issuance or sale of shares of Common Stock and
   warrants to be issued concurrently herewith, if any, and upon the issuance
   or sale of shares of Common Stock upon the exercise of such warrants;

                (iii) upon (A) the issuance of options pursuant to any
   employee, executive or director benefit, incentive, stock option or profit
   sharing plans of the Company which plans are in effect on December 31,
   1997 or, (B) the sale by the Company of any shares of Common Stock
   pursuant to the exercise of any such options; or

                (iv) upon the issuance or sale by the Company of any shares
   of Common Stock pursuant to the exercise of any options or warrants or
   upon the conversion of any convertible subordinated debentures previously
   issued and outstanding on December 31, 1997; or

                (v) if the amount of said adjustment shall be less than $0.02
   per Share; provided, however, that in such case any adjustment that would
   otherwise be required then to be made shall be carried forward and shall
   be made at the time of and together with the next subsequent adjustment
   which, together with any adjustment so carried forward, shall amount to at
   least $0.02 per Share.

            (g)  Dividends and Other Distribution with Respect to Outstanding
   Securities. In the event that the Company shall at any time prior to the
   exercise of all Warrants declare a dividend (other than a dividend
   consisting solely of shares of Common Stock or a cash dividend or
   distribution payable out of current or retained earnings) or otherwise
   distribute to its stockholders any monies, assets, property, rights,
   evidences of indebtedness, securities (other than shares of Common Stock),
   whether issued by the Company or by another person or entity, or any other
   thing of value, the Holder of the unexercised Warrants shall thereafter be
   entitled, in addition to the shares of Common Stock or other securities
   receivable upon the exercise thereof, to receive, upon the exercise of




   <PAGE>                             8
<PAGE>






   such Warrants, the same monies, property, assets, rights, evidences or
   indebtedness, securities or any other thing of value that it would have
   been entitled to receive at the time of such dividend or distribution. At
   the time of any such dividend or distribution, the Company shall make
   appropriate reserves to ensure the timely performance of the provisions of
   this subparagraph (g).

            (h)  Subscription Rights for Shares of Common Stock or Other
   Securities. In the case the Company or any affiliate of the Company shall
   at any time after December 31, 1997 and prior to the exercise of all the
   Warrants issue any rights to subscribe for shares of Common Stock or any
   other securities of the Company or of such affiliate to all the
   stockholders of the Company, the Holder of the unexercised Warrants shall
   be entitled, in addition to the shares of Common Stock or other securities
   receivable upon the exercise of the Warrants, to receive such rights on a
   pro rata basis at the time such rights are distributed to the other
   stockholders of the Company.

            (i) Statement on Warrants. Irrespective of any adjustments in the
   Exercise Price or the number or kind of shares purchasable upon the
   exercise of the Warrants, the certificates representing the Warrants
   theretofore or thereafter issued may continue to express the same price
   and number and kind of shares as are stated in the certificate
   representing the Warrants initially issuable.

        8.  Notices to Warrant Holders. Nothing contained in this
   Certificate shall be construed as conferring upon the Holder the right to
   vote or to consent or to receive notice as a stockholder in respect of any
   meetings of stockholders for the election of directors or any other
   matter, or as having any rights whatsoever as a stockholder of the
   Company. If, however, at any time prior to the expiration of the Warrants
   and their exercise, any of the following events shall occur:

            (a)  the Company shall take a record of the holders of its shares
   of Common Stock for the purpose of entitling them to receive a dividend or
   distribution payable otherwise than in cash, or a cash dividend or
   distribution payable otherwise than out of current or retained earnings,
   as indicated by the accounting treatment of such dividend or distribution
   on the books of the Company; or

            (b)  the Company shall offer to all the holders of its Common
   Stock any additional shares of capital stock of the Company or securities
   convertible into or exchangeable for shares of capital stock of the
   Company, or any option, right or warrant to subscribe therefor; or

            (c)  a dissolution, liquidation or winding-up of the Company
   (other than in connection with a consolidation or merger) or a sale of all
   or substantially all of its property, assets and business as an entirety
   shall be proposed; or

            (d)  there shall be any capital reorganization or
   reclassification of the capital stock of the Company, or consolidation or




   <PAGE>                             9
<PAGE>






   merger of the Company with another entity;

   then, in any one or more of said events, the Company shall give written
   notice of such event at least 20 days prior to the date fixed as a record
   date or the date of closing the transfer books for the determination of
   the stockholders entitled to such dividend, distribution, convertible or
   exchangeable securities or subscription rights, options or warrants, or
   entitled to vote on such proposed dissolution, liquidation, winding-up or
   sale. Such notice shall specify such record date or the date of closing
   the transfer books, as the case may be. Failure to give such notice or any
   defect therein shall not affect the validity of any action taken in
   connection with the declaration or payment of any such dividend or
   distribution, or the issuance of any convertible or exchangeable
   securities or subscription rights, options or warrants, or any proposed
   dissolution, liquidation, winding-up or sale.

        9.  Reservation and Listing of Securities.

            (a)  The Company covenants and agrees that at all times during
   the period the Warrants are exercisable, the Company shall reserve and
   keep available, free from preemptive rights, out of its authorized and
   unissued shares of Common Stock or out of its authorized and issued shares
   of Common Stock held in its treasury, solely for the purpose of issuance
   upon exercise of the Warrants, such number of shares of Common Stock as
   shall be issuable upon the exercise of the Warrants.

            (b)  The Company covenants and agrees that, upon exercise of the
   Warrants and payment of the Exercise Price therefor, all shares of Common
   Stock issuable upon such exercise shall be duly and validly issued, fully
   paid and non-assessable, and the Holder shall receive good and valid
   record title to such shares of Common Stock, free and clear from all taxes
   with respect to the issue or sale thereof and any claim, lien, security
   interest, mortgage, pledge, charge or other encumbrance of any nature
   whatsoever, except as may have been created by the Holder, and such shares
   of Common Stock shall not be subject to the preemptive rights of any
   stockholder.

            (c)  As long as the Warrants shall be outstanding, the Company
   shall use its best efforts to cause all shares of Common Stock issuable
   upon the exercise of the Warrants to be listed on or quoted by Nasdaq.

        10.  Survival. All agreements, covenants, representations and
   warranties herein shall survive the execution and delivery of this
   Certificate and any investigation at any time made by or on behalf of any
   party hereto and the exercise, sale and purchase of the Warrants and the
   Common Stock (and any other securities or properties) issuable on exercise
   hereof.

        11.  Remedies. The Company agrees that the remedies at law of the
   Holder, in the event of any default or threatened default by the Company
   in the performance of or compliance with any of the terms of hereof, may
   not be adequate and such terms may, in addition to and not in lieu of any




   <PAGE>                             10
<PAGE>






   other remedy, be specifically enforced by a decree of specific performance
   of any agreement contained herein or by an injunction against a violation
   of any of the terms hereof or otherwise.

        12.  Registered Holder. The Company may deem and treat the registered
   Holder(s) hereof as the absolute owner(s) of this Certificate and the
   Warrants represented thereby (notwithstanding any notation of ownership or
   other writing hereon made by anyone), for the purpose of any exercise of
   the Warrants, and of any distribution to the Holder(s) hereof, and for all
   other purposes, and the Company shall not be affected by any notice to the
   contrary.

        13.  Notices. All notices and other communications from the Company
   to the Holder of the Warrants represented by this Certificate shall be
   mailed by first class registered or certified airmail, postage prepaid, to
   the last address of such Holder as it shall appear on the books of the
   Company maintained at the Company s principal office upon or to such other
   address as the Holder may have specified to the Company in writing.

        14.  Headings. The headings contained herein are for convenience of
   reference only and are not part of this Warrant.

        15.  Governing Law. This Warrant shall be deemed to be a contract

                              Due December 31, 2002

   $______________                          Dated as of December 31, 1997
                                            New York, New York

   FOR VALUE RECEIVED, the undersigned, METALCLAD CORPORATION, a Delaware
   corporation (herein, together with any successor, referred to as the
   "Company"), hereby promises to pay to ________________________________or
   its registered assigns, the principal sum of $__________ on December 31,
   2002 without interest, except in the event of the occurrence of an Event
   of Default. Upon the occurrence of an Event of Default (hereinafter
   defined), interest at the Default Rate shall be paid on the "Discounted
   Present Value" of this Note. As used herein "Discounted Present Value"
   shall be based on a simple interest rate of 9 1/3% per annum without
   compounding and shall be calculated in accordance with the following
   formula:
                                        n
                                      ----
                   PP + (46 2/3% PP x 1826)

   wherein PP equals the "Purchase Price" (hereinafter defined) of this Note,
   n equals the number of days elapsed from and including the date of
   issuance of this Note to and including (A) the date of payment pursuant to
   a demand by the Noteholder for redemption pursuant to the exercise by the
   Noteholder of its contingent right of redemption or (B) the date of




   <PAGE>                             1
<PAGE>






   payment pursuant to the exercise by the Company of its contingent right of
   prepayment or (C) upon the occurrence of an Event of Default, as the case
   may be, and 1826 equals the total number of days from and including the
   date of issuance to and including the date of maturity of the Note
   (December 31, 1997 through and including December 31, 2002). Upon the
   occurrence of an Event of Default, the Discounted Present Value of this
   Note shall become immediately due and payable and shall bear interest at
   the Default Rate from the date of such occurrence until paid in full.

        The "Default Rate" shall be a per annum interest rate equal to the
   greater of (w) 15% or (x) the sum of 60/o plus the rate announced from
   time to time by Citibank, N.A. as its prime or stated rate for unsecured
   short-term U.S. dollar commercial loans within the United States (the
   "Prime Rate"), provided, however, that in no event shall the Default Rate
   exceed the maximum nonusurious per annum interest rate permitted by
   applicable law. As used herein, the term "Purchase Price" shall mean the
   principal amount of this Note multiplied times .68181819, and the term
   "Event of Default" shall have the meaning set forth in the "Purchase
   Agreement" hereinafter referred to.

        If any payment of Default interest due hereunder becomes due and
   payable on a day which is not a "Business Day" (as defined in the Purchase
   Agreement), the due date thereof shall be the next preceding day which is
   a Business Day, and the interest payable on such next preceding Business
   Day shall be the interest which would otherwise have been payable on the
   due date which was not a Business Day.

        Payments of principal and interest shall be made in lawful money of
   the United States of America at the principal office of the Company at
   Newport Beach, California, or at such other place as the Company shall
   have designated for such purpose to the holder hereof in writing, as
   provided in the Purchase Agreement referred to below, or to the address or
   account designated by the holder hereof for such purpose.

        This Note is one of a duly authorized issue of Zero Coupon Secured
   Notes in an aggregate principal amount of U.S. $2,200,000 maturing
   December 31, 2002 issued pursuant to a Purchase Agreement dated as of
   December 31, 1997 between the Company and the purchasers ("Purchasers"
   and, individually, a "Purchaser") named in the Purchase Agreement
   ("Purchase Agreement").

        This Note is subject to the provisions of, is entitled to the
   benefits of, and is subject to the rights of the Company and the
   obligations of the holder set forth in the Purchase Agreement which
   provide, inter alia that in the event that the "Market Price" (as defined
   in the Purchase Agreement) of the Common Stock of the Company ("Common
   Stock") shall equal or exceed U.S. $1.50 per share for not less than ten
   consecutive trading days (hereinafter sometimes referred to as the
   "Trigger Event"): (I) this Note shall automatically become convertible,
   and may thereafter be converted at the option of the holder hereof
   (subject to the rights of the Company under subdivision (iv) below and the
   last sentence of the succeeding paragraph hereof) without necessity of




   <PAGE>                             2
<PAGE>






   further act (other than the receipt by the holder from the Company of
   notice that the "Trigger Event" has occurred, which notice the Company is
   obliged to give pursuant to the terms of the Purchase Agreement within ten
   calendar days after the occurrence of the "Trigger Event"), in whole or in
   part (in increments of not less than U.S. $50,000.00 of the Purchase Price
   of this Note) into the Common Stock ("Common Stock") of the Company at the
   conversion rate of 667 shares of Common Stock for each U.S. $1,000.00 of
   such Purchase Price subject to adjustment pursuant to the anti-dilution
   provisions set forth in the Purchase Agreement and referred to therein as
   the "OFW Rachet Clause" (said conversion rate as the same may be so
   adjusted being hereinafter sometimes referred to as the "Conversion
   Rate"), (ii) at such time, if ever, as this Note becomes convertible as
   hereinabove set forth, and if this Note is so converted, the right of the
   holder hereof to receive any and all interest ("Total Interest") in
   respect of this Note, whether accrued or to be accrued, which amount of
   interest from issuance through maturity is agreed to be equal to .318181
   multiplied times the face amount of this Note so that if this Note becomes
   convertible following the occurrence of a "Trigger Event" and is
   converted, the right of the holder of this Note to receive Total Interest
   shall be canceled, (iii) the Company shall forthwith issue to the holder
   of this Note 1,000 Warrants "Warrants" as defined in the Purchase
   Agreement to purchase shares of the Common Stock of the Company at an
   exercise price of $1.50 per share for each $1,000 portion of the Purchase
   Price of this Note, pro rated for amounts of less than $1,000 (said
   exercise price as the same may be adjusted pursuant to the OFW Rachet
   Clause, being hereinafter sometimes referred to as the "Warrant Exercise
   Price"), said Warrants to expire at 5:00 p.m., California time, on
   December 31, 2002, and (iv) shall be converted upon (A) the occurrence of
   a "Trigger Event" and the receipt of notice thereof by the holder from the
   Company, and (B) notice that the Company has exercised its right to
   require the holder hereof to convert this Note into shares of the
   Company s Common Stock at the Conversion Rate upon receipt by the holder
   from the Company of not less than 5 nor more than 15 calendar days after
   the occurrence of an "MTLC Optional Conversion Event." As used herein, the
   term "MTLC Optional Conversion Event" shall mean the occurrence of any
   period during which the Market Price of the Common Stock equals or exceeds
   $3.00 per share for not less than 60 consecutive trading days, it being
   understood that the failure of the Company to give the holder, and the
   holder to receive, such notice of the occurrence of an MTLC Optional
   Conversion Event within such 15-day period shall cause the lapse of the
   Company s right to require such conversion in respect of such MTLC
   Optional Conversion Event without prejudice to the further exercise of
   such right upon the occurrence of another MTLC Optional Conversion Event
   prior to the maturity of this Note provided the Company gives, and the
   holder receives, such notice of the occurrence of such MTLC Conversion
   Event within 15 calendar days following the occurrence thereof.

        Notwithstanding the foregoing, the holder of this Note shall have the
   right, exercisable at any time on or after April 15, 1999, of requiring
   the Company to redeem this Note ("Mandatory Redemption") at a price equal
   to the Discounted Present Value hereof as at the date payment is made
   pursuant to such demand for redemption. In the event of such a demand for




   <PAGE>                             3
<PAGE>






   redemption, payment shall be effected within 30 calendar days following
   the date of such demand and concurrently with such payment the Company
   will issue to the holder of this Note 1,000 Warrants for each $1,000.00 of
   the Purchase Price of the Notes being redeemed (provided such Warrants
   have not been previously issued to the Noteholder). Further,
   notwithstanding the foregoing, the Company shall have the right at any
   time after April 15, 1999 and prior to receipt by the Company of notice
   from any Noteholder of the exercise of any right of conversion it may then
   have to prepay all the Notes at their Discounted Present Value calculated
   to the date of such prepayment provided concurrently therewith the Company
   issues to the holders of the Notes, 1,000 Warrants for each $1,000.00 of
   the Purchase Price thereof (provided such Warrants have not been
   previously issued to the Noteholder)

        The Note is transferable only upon the terms and conditions specified
   in the Purchase Agreement.

        If an Event of Default, as defined in Section 7 of the Purchase
   Agreement, shall occur and be continuing, the Discounted Present Value of
   this Note may be declared immediately due and payable in the manner and
   with the effect provided in the Purchase Agreement and this Note.

        No reference herein to the Purchase Agreement and no provision hereof
   or thereof shall alter or impair the obligations of the Company, which are
   absolute and unconditional, to pay the principal hereof and interest
   hereon at the respective times and places specified herein and in the
   Purchase Agreement.

        This Note is delivered in and shall be construed and enforced in
   accordance with and governed by the laws of the State of New York (other
   than any conflict of laws rules which might result in the application of
   the laws of any other jurisdiction).

        Subject to the provisions of Section 4.3 of the Purchase Agreement,
   the Company may treat the person in whose name this Note is registered as
   the owner and holder of this Note for the purpose of receiving payment of
   principal of, premium, if any, and interest on this Note and for all other
   purposes whatsoever, and the Company shall not be affected by any notice
   to the contrary (except that the Company shall comply with the provisions
   of Section 4.3 of the Purchase Agreement regarding the issuance of a new
   Note or Notes to permitted transferees).

        IN WITNESS WHEREOF, Metalclad Corporation has caused this Note to be
   duly executed and delivered as of December 31, 1997.

        THIS PLEDGE AGREEMENT is entered into as of this 31st day of December

   simultaneously herewith purchasing $2,200,000 aggregate principal amount
   of the Pledgor s Zero Coupon Secured Notes due December 31, 2002 (the
   "Notes");

        WHEREAS, as more specifically set forth in the Purchase Agreement and
   the Notes, upon the occurrence of certain contingent events not certain to
   occur, (i) Pledgor may become obligated to issue warrants (the "Warrants")
   to purchase an aggregate of 1,500,000 shares of the Pledgor s Common

        WHEREAS, as a condition precedent and as an inducement to the
   Purchasers to purchase the Notes, the Pledgor has agreed to grant to the
   Agent for the benefit of the Purchasers (as defined in the Purchase

   more fully set forth herein;

        NOW, THEREFORE, in consideration of the foregoing and other good and

   any provision of any law or regulation or any order of any governmental
   authority or any judgment of any court applicable to the Pledgor or its

   and (v) will not result in the creation, or imposition of any lien, charge
   or encumbrance of any nature whatsoever upon any property or assets of the
   Pledgor other than pursuant to this Pledge Agreement;

            (c)  this Pledge Agreement constitutes the legal, valid and
   binding obligation of the Pledgor, enforceable in accordance with its
   terms, subject (i) as to the enforcement of remedies, to applicable
   bankruptcy, reorganization, insolvency and other laws affecting creditors
   rights generally and to moratorium laws from time to time in effect, and
   (ii) to general equitable principles;

   interests or encumbrances;

            (g)  the Pledgor has the right to pledge and to grant the
   security interest in the Collateral free of any encumbrances, and without
   the consent of the creditors of the Pledgor or any other person or any
   governmental authority whatsoever;

            (i)  there is no material pending legal or governmental
   proceeding to which the Pledgor is a party or to which any of its
   properties is subject, which proceeding will materially affect (i) the
   Pledgor s ability to perform its obligations hereunder or (ii) the
   Collateral;

            (j)  this Pledge Agreement creates in favor of the Agent a valid,
   binding and enforceable security interest in, and lien upon, all right,
   title and interest of the Pledgor in the Collateral and, upon delivery of

   and prior security interest in and lien upon all right, title and interest
   of the Pledgor in the Collateral; and

<PAGE>






        6.  Voting Rights; Dividends; Etc.

            (a)  The Pledgor shall be entitled to exercise any and all voting
   and/or consensual rights and powers accruing to owners of the Pledged
   Securities or any part thereof for any purpose not inconsistent with the
   terms hereof, at all times, except as expressly provided in Section 6(c)
   below.

             (b)  Any dividends or distributions of any kind whatsoever (in
   cash or otherwise) received by the Pledgor, whether declared on a regular,
   periodic basis or resulting from a subdivision, combination, or
   reclassification of the outstanding capital stock of the issuer, in
   respect of the Pledged Securities, or received in exchange for the Pledged
   Securities, or other Collateral or any part thereof or as a result of any
   merger, consolidation, acquisition, or other exchange of assets to which
   the issuer may be a party, or otherwise, shall, be and become part of the
   Collateral pledged hereunder and shall immediately be delivered to the
   Agent to be held subject to the terms hereof.

            (c)  Upon the occurrence and during the continuance of an Event
   of Default, all rights of the Pledgor to exercise the voting and/or
   consensual rights and powers which it is entitled to exercise pursuant to
   Section 6(a) shall cease, and all such rights shall thereupon become
   vested in the Agent, which shall have the sole and exclusive right and
   authority to exercise such voting and/or consensual rights and powers.

        7.  Remedies Upon Default.

            (a)  If an Event of Default shall have occurred and be
   continuing, the Agent may sell the Collateral, or any part thereof, at
   public or private sale or at any broker s board or on any securities
   exchange, for cash, upon credit or for future delivery as the Agent shall
   deem appropriate subject to the terms hereof or as otherwise provided in
   the New York Uniform Commercial Code. The Agent shall be authorized at any
   such sale (if it deems it advisable so to do) to restrict to the full
   extent permitted by applicable law the prospective bidders or purchasers
   to persons who will represent and agree that they are purchasing the
   Collateral for their own account for investment and not with a view to the
   distribution or sale thereof, and upon consummation of any such sale the
   Agent shall have the right to assign, transfer, and deliver to the
   purchaser or purchasers thereof the Collateral so sold. Each such
   purchaser at any such sale shall hold the property sold absolutely, free
   from any claim or right on the part of the Pledgor.

            (b)  The Agent shall give the Pledgor ten calendar days written
   notice of its intention to make any such public or private sale, or sale
   at any broker s board or on any such securities exchange, or of any other
   disposition of the Collateral. Such notice, in the case of public sale,
   shall state the time and place for such sale and, in the case of sale at a
   broker s board or on a securities exchange, shall state the board or
   exchange at which such sale is to be made and the day on which the
   Collateral, or portion thereof, will first be offered for sale at such




   <PAGE>                             4
<PAGE>






   board or exchange. Any such public sale shall be held at such time or
   times within ordinary business hours and at such place or places as the
   Agent may fix and shall state in the notice of such sale. At any such
   sale, the Collateral, or portion thereof, to be sold may be sold in one
   lot as an entirety or in separate parcels, as the Agent may (in its sole
   and absolute discretion) determine. The Agent shall not be obligated to
   make any sale of the Collateral if it shall determine not to do so,
   regardless of the fact that notice of sale of the Collateral may have been
   given. The Agent may, without notice or publication, adjourn any public or
   private sale or cause the same to be adjourned from time to time by
   announcement at the time and place fixed for sale, and such sale may,
   without further notice, be made at the time and place to which the same
   was so adjourned. In case the sale of all or any part of the Collateral is
   made on credit or for future delivery, the Collateral so sold shall be
   retained by the Agent until the sale price is paid by the purchaser or
   purchasers thereof, but the Agent shall not incur any liability in case
   any such purchaser or purchasers shall fail to take up and pay for the
   Collateral so sold and, in case of any such failure, such Collateral may
   be sold again upon like notice. At any sale or sales made pursuant to this
   Section 7, the Agent may bid for or purchase, free from any claim or right
   of whatsoever kind, including any equity of redemption, of the Pledgor,
   any such demand, notice, claim, right or equity being hereby expressly
   waived and released, any or all of the Collateral offered for sale, and
   may make any payment on the account thereof by using any claim for moneys
   then due and payable to the Purchasers by the Pledgor as a credit against
   the purchase price; and the Agent, upon compliance with the terms of sale,
   may hold, retain and dispose of the Collateral without further
   accountability therefor to the Pledgor or any, third party. The Agent
   shall in any such sale make no representations or warranties with respect
   to the Collateral or any part thereof and shall not be chargeable with any
   of the obligations or liabilities of the Pledgor with respect thereto. As
   an alternative to exercising the power of sale herein conferred upon it,
   the Agent may proceed by a suit or suits at law or in equity to foreclose
   upon the Collateral under this Pledge Agreement and to sell the
   Collateral, or any portion thereof, pursuant to a judgment or decree of a
   court or courts having competent jurisdiction.

        8.  Application of Proceeds of Sale. The proceeds of sale of the
   Collateral sold pursuant to Section 7 hereof shall be distributed by the
   Agent (after deduction of all costs and expenses incurred by the Agent
   while enforcing its rights pursuant to this Pledge Agreement, including,
   without limitation, reasonable attorneys  fees and expenses) to the
   holders of the Notes then outstanding, allocated among such holders in
   proportion, as nearly as practicable, to the respective unpaid principal
   amount of Notes then held by each such holder, to be applied by each such
   holder to the Obligations in such manner as it may deem appropriate.

        9.  Agent Appointed Attorney-in-Fact. Upon the occurrence and during
   the continuance of an Event of Default, the Pledgor hereby appoints the
   Agent its attorney-in-fact for the purpose of carrying out the provisions
   of this Pledge Agreement and the pledge of, and the grant of a security
   interest in, the Collateral hereunder and the taking of any action and the




   <PAGE>                             5
<PAGE>






   execution of any instrument which the Agent may deem necessary or
   advisable to accomplish the purposes hereof, which appointment is
   irrevocable and coupled with an interest. Without limiting the generality
   of the foregoing, the Agent shall have the right and power to receive,
   endorse and collect all checks and other orders for the payment of money
   made payable to the Pledgor representing any dividend or other
   distribution payable in respect of the Collateral or any part thereof and
   to give full discharge for the same.

        10.  Federal Securities Laws. In view of the position of the Pledgor
   in relation to the Collateral, or because of other present or future
   circumstances, a question may arise under the Securities Act of 1933, as
   amended, as now or hereafter in effect, or any similar statute hereafter
   enacted analogous in purpose or effect (such Act and any such similar
   statute as from time to time in effect being hereinafter called the
   "Federal Securities Laws"), with respect to any disposition of the
   Collateral permitted hereunder. The Pledgor understands that compliance
   with the Federal Securities Laws may very strictly limit the course of
   conduct of the Agent if the Agent were to attempt to dispose of all or any
   part of the Collateral, and may also limit the extent to which or the
   manner in which any subsequent transferee of any Collateral may dispose of
   the same. Similarly, there may be other legal restrictions or limitations
   affecting the Agent in any attempt to dispose of all or any part of the
   Collateral under applicable blue sky or other state securities laws, or
   similar laws analogous in purpose or effect. Under applicable law, in the
   absence of an agreement to the contrary, the Agent may perhaps be held to
   have certain general duties and obligations to the Pledgor to make some
   effort towards obtaining a fair price even though the Obligations may be
   discharged or reduced by the proceeds of a sale at a lesser price. The
   Pledgor clearly understands that the Agent is not to have any such general
   duty or obligation to it, and the Pledgor will not attempt to hold the
   Agent responsible for selling all or any part of the Collateral at an
   inadequate price, even if the Agent shall accept the first offer received
   or does not approach more than one possible purchaser. Without limiting
   the generality of the foregoing, the provisions of this Section 10 would
   apply if, for example, the Agent were to place all or any part of the
   Collateral for private placement by an investment banking firm, or if such
   investment banking firm purchased all or any part of the Collateral for
   its own account, or if the Agent placed all or any part of the Collateral
   privately with a purchaser or purchasers.

        11.  Financing Statements. So long as the Obligations are outstanding
   and the security interest hereunder shall not have terminated in
   accordance with Section 13 hereof, the Pledgor agrees to execute and
   deliver to the Agent such UCC financing statements and any amendments
   thereto or continuations thereof and any other documents or instruments
   and to give such notices as the Agent may deem necessary or desirable to
   perfect the lien of the Agent on the Collateral. If the Pledgor does not
   execute and deliver to the Agent any such financing statement, amendment
   or other document or instrument or give such notice within five calendar
   days after requested by the Agent, then the Secured Party is hereby
   authorized by the Pledgor to file such items or give such notice, without




   <PAGE>                             6
<PAGE>






   the signature of the Pledgor or to execute such items as attorney-in-fact
   for the Pledgor. The Pledgor further authorizes the Agent, upon the
   occurrence and during the continuation of an Event of Default, to notify
   any obligors on instruments that all sums payable to the Pledgor relating
   to the collateral shall be paid directly to the Agent.

        12.  Further Assurances. Upon the request of the Agent, the Pledgor
   hereby agrees duly to execute and deliver, or cause to be duly executed
   and delivered, from time to time, at the cost and expense of the Pledgor,
   such further instruments as may be necessary or proper, in the reasonable
   judgment of the Agent, to carry out the provisions and purposes of this
   Pledge Agreement and to do all things necessary or advisable, in the
   judgment of the Agent, to perfect and preserve the pledge and the security
   interests of the Agent hereunder and in the Collateral or any portion

   forth in this Agreement.

        3.  Requested Registration

            (a)  Request for Registration. If the conditions set forth in
   Section 2 above apply and the Company shall receive from a Holder or
   Holders, at any time or times not later than five years after the date of
   this Agreement, a written request that the Company effect a registration
   with respect to at least 200,000 of the Registrable Shares (such number to
   be appropriately adjusted for any stock dividends, combinations or similar
   transactions with respect to such shares), the Company will promptly give
   written notice of the proposed registration to all other Holders. The
   Company will then, as soon as practicable, use its best efforts to effect
   such registration (including, without limitation, filing post-effective
   amendments, appropriate qualifications under applicable blue sky or other
   state securities laws, and appropriate compliance with the Securities Act)
   as would permit or facilitate the sale and distribution of all or such
   portion of the Registrable Shares as are specified in such request,
   together with all or such portion of the Registrable Shares of each Holder
   joining in such request as are specified in a written notification
   received by the Company within 20 days after such written notice from the
   Company is given to such Holder in accordance with Section 14(c).

            (b)  Limitations on Registration Obligation. The Company will not




   <PAGE>                             3
<PAGE>






   be obligated to effect, or to take any action to effect, a Demand
   Registration pursuant to this Section 3:

                 (i)  If pursuant to a Demand Registration a registration
   statement has been declared effective within the prior 12-month period;

                 (ii)  After the Company has initiated a Demand Registration
   pursuant to this Section 3 (counting for these purposes only (A)
   registrations which have been declared or ordered effective and pursuant
   to which securities have been sold, and (B) registrations which have been
   withdrawn by the Holders as to which the Holders have not elected to bear
   the Registration Expenses pursuant to Section 5 and would, absent such
   election, have been required to bear such expenses);

                 (iii)  In any particular jurisdiction in which the Company
   would be required to execute a general consent to service of process in
   effecting such registration, qualification or compliance, unless the
   Company is already subject to service in such jurisdiction and except as
   may be required by the Securities Act;

                 (iv)  During the period starting with the date 60 days prior
   to the Company s good faith estimate of the date of filing of, and ending
   on a date 180 days after the effective date of, a Company-initiated
   registration (other than a registration of securities in a Rule 145
   transaction or with respect to an employee benefit plan), provided that
   the Company is actively employing in good faith all reasonable efforts to
   cause the registration to become effective; or

                 (v)  If the requesting Holder(s) proposed to dispose of
   Registrable Shares which may be immediately registered on Form S-3
   pursuant to a request made under Section 6.

            (c)  Company s Right to Defer Registration. Subject to clauses
   (i) through (v) of Section 3(b), the Company shall file a registration
   statement covering the Registrable Shares requested to be registered under
   Section 3(a) as soon as practicable after receipt of the request of the
   requesting Holder(s); provided, however, that if, (i) in the good faith
   judgment of the Board of Directors of the Company, such registration would
   be seriously detrimental to the Company and the Board of Directors of the
   Company concludes, as a result, that it is essential to defer the filing
   of such registration statement at such time, and (ii) the Company shall
   furnish to all the Holders a certificate signed by the President of the
   Company stating such facts, then the Company shall have the right to defer
   such filing for the period during which such disclosure would be seriously
   detrimental, provided that (except as permitted in Section 3(b)(iv) above)
   the Company may not defer the filing for a period of more than 90 days
   after receipt of the request of the requesting Holder(s) and, provided
   further, that the Company shall not defer its obligation in this manner
   more than once in any 12-month period.

            (d)  Other Included Securities. A registration statement filed
   pursuant to the request of a Holder or Holders under Section 3(a) may,
   subject to the provisions of Sections 3(e), include securities of the
   Company held by other persons who have been granted registration rights by


   <PAGE>                             4
<PAGE>






   the Company and may include securities of the Company being sold for the
   account of the Company.

            (e)  Underwritten Offering. If a Demand Registration pursuant to
   this Section 3 is for a registered public offering involving an
   underwriting, the Company shall so advise the Holders as part of the
   notice given pursuant to Section 3(a). In such event, the right of any
   Holder to registration pursuant to this Section 3 shall be conditioned
   upon such Holder s participation in the underwriting arrangements required
   by this Section 3(e), and the inclusion of such Holders Registrable Shares
   in the underwriting to the extent requested shall be limited as provided
   below. The Company shall (together with all Holders and other persons
   proposing to distribute their securities through such underwriting) enter
   into an underwriting agreement in customary form with the representative
   of the underwriter(s) selected for such underwriting by the Holders who
   hold a majority of the Registrable Shares held by all the Holders with
   respect to that underwriting, provided that the underwriter(s) shall be
   reasonably acceptable to the Company. Notwithstanding any other provision
   of this Section 3, if the representative of the underwriter(s) advises the
   Company and the Holders in writing that marketing factors require a
   limitation on the number of shares to be underwritten, the representative
   may (subject to the limitations set forth below) limit the number of
   Registrable Shares and other securities to be included in the
   underwriting. The Company shall so advise all participating Holders and
   the number of shares that may be included in the registration and
   underwriting shall be allocated: first to the Registrable Shares, with the
   allocation among Registrable Shares held by Holders who have requested
   inclusion in the registration in proportion, as nearly as practicable, to
   the respective amounts of Registrable Shares held by such Holders and
   properly requested to be included at the time of filing the registration
   statement; second, to shares being sold for the account of the Company;
   and then, to shares being sold for the account of other Persons. Any
   Registrable Shares so excluded from the underwriting by reason of the
   representative s marketing limitation shall be withdrawn from such
   registration. To facilitate the allocation of shares in accordance with
   the above provisions, the Company or the representative of the
   underwriter(s) may round the number of registered shares allocated to any
   Holder or other shareholder to the nearest 100 shares. If a Holder who has
   requested inclusion in an underwritten Demand Registration as provided
   above does not agree to the terms of the underwriting, that Holder s
   shares may be excluded from the underwriting by written notice from the
   Company or the representative of the underwriter(s) and the shares so
   excluded shall be withdrawn from the registration. If shares are so
   excluded from the underwriting because of a failure to agree to its terms
   and the number of Registrable Shares to be included in the underwriting
   was previously reduced as a result of marketing factors pursuant to this
   Section 3(e), then, with the permission of the representative of the
   underwriter(s) the Company shall offer to all Holders who have retained
   rights to include Registrable Shares in the underwriting the right to
   include additional Registrable Shares in an aggregate amount equal to the
   number of shares so excluded. The registration of such additional
   Registrable Shares shall be allocated among the Holders requesting the
   additional inclusion pro rata in accordance with the numbers of their
   Registrable Shares which are otherwise to be included in the registration.

        4.  Participation Registration

            (a)  Registration Right. If the conditions set forth in Section 2
   above apply and, after the date of this Agreement, the Company shall
   determine to register any of its securities either for its own account or
   the account of a security holder or holders (other than pursuant to
   Section 3 or 6), except for a registration relating solely to employee
   benefit plans, a registration relating solely to a Rule 145 transaction, a
   registration on any registration form that would not permit secondary
   sales of Registrable Shares or a registration filed more than five years
   after the date of this Agreement, the Company will, in two such instances:

                  (i)  Promptly give to each Holder written notice thereof;

                  (ii)  Use its best efforts to include in such registration
   (and any related qualification under blue sky laws or other compliance),
   except as set forth in Section 4(b) below, and in any underwriting
   involved therein, all the Registrable Shares specified in a written
   request or requests made by any Holder within 15 days after the written
   notice from the Company described in clause (i) above is given to that
   Holder. Such written request may specify all or a part of a Holder s
   Registrable Shares.

            (b)  Underwritten Offering. If the registration of which the
   Company gives notice under Section 4(a) is for a registered public
   offering involving an underwriting, the Company shall so advise the
   Holders as a part of the written notice given pursuant to Section 4(a)(i).
   In such event, the right of any Holder to registration pursuant to this
   Section 4 shall be conditioned upon such Holder s participation in such
   underwriting and the inclusion of such Holder s Registrable Shares in the
   underwriting to the extent provided herein. All Holders proposing to
   distribute their securities through the underwriting shall (together with
   the Company and any other persons proposing to distribute their securities
   through the underwriting) enter into an underwriting agreement in
   customary form with the representative of the underwriter(s) selected by
   the Company. Notwithstanding any other provision of this Section 4, if the
   representative of the underwriter(s) advises the Company in writing that
   marketing factors require a limitation on the number of shares to be
   underwritten, the representative may (subject to the limitations set forth
   below) limit the number of Registrable Shares to be included in the
   registration and underwriting; provided that the value of the included
   Registrable Shares shall be at least 20% of the total value of the
   securities included in the registration. The Company shall so advise all
   Holders requesting to participate in the registration and the number of
   shares that may be included in the registration and underwriting shall be
   allocated: first, to the Company for securities being sold for its own
   account; second, among Registrable Shares held by all Holders who have
   requested inclusion in the registration in proportion, as nearly as
   practicable, to the respective amounts of Registrable Shares held by such
   Holders and properly requested to be included at the time of filing the
   registration statement; and then to shares being sold for the accounts of
   other Persons. Any Registrable Shares so excluded from the underwriting by
   reason of the representative s limitation shall be withdrawn from such
   registration. To facilitate the allocation of shares in accordance with


   <PAGE>                             6
<PAGE>






   the above provisions, the Company or the representative of underwriter(s)
   may round the number of shares allocated to any Holder or other
   shareholder to the nearest 100 shares. If a Holder who has requested
   inclusion in the registration does not agree to the terms of the
   underwriting, that Holder s shares may be excluded from the underwriting
   by written notice from the Company or the representative of the
   underwriter(s) and the shares so excluded shall be withdrawn from the
   registration. If shares are so excluded from the underwriting because of a
   failure to agree to its terms and the number of shares of Registrable
   Shares to be included in the underwriting was previously reduced as a
   result of marketing factors pursuant to this Section 4(b), then, with the
   permission of the representative of the underwriter(s) the Company shall
   offer to all Holders who have retained rights to include Registrable
   Shares in the underwriting the right to include additional Registrable
   Shares in an aggregate amount equal to the number of shares so excluded.
   The registration of such additional Registrable Shares shall be allocated
   among the Holders requesting the additional inclusion pro rata in
   accordance with the numbers of their Registrable Shares which are
   otherwise to be included in the registration.

        (c)
   Right to Terminate Registration. The Company shall have the right to
   terminate or withdraw any registration initiated by it under this Section
   4 prior to the registration s effectiveness, whether or not any Holder has
   elected under this Section 4 to include shares in the registration.

        5.  Expenses of Registration

            All Registration Expenses incurred in connection with any
   registration, qualification or compliance pursuant to Sections 3 and 4
   shall be borne by the Company. All Registration Expenses incurred in
   connection with the registration of  Registrable Shares under Section 6
   shall be borne by the Holders participating in the registration pro rata
   on the basis of the numbers of Registrable Shares so registered on their
   behalf, provided that, if other shares are included in the registration,
   the Registration Expenses shall be reasonably allocated among the Holders,
   the Company and other participating shareholders based on the numbers of
   their shares that are registered. A Holder or Holders may elect to bear
   without reimbursement by the Company the Registration Expenses for a
   Demand Registration proceeding begun by them pursuant to Section 3 and
   subsequently withdrawn by them. In such a case, the registration
   proceeding shall not be counted for purposes of Section 3(b)(ii). If a
   withdrawal of a Demand Registration by a Holder is based upon material
   adverse information relating to the Company that is different from the
   information known or available (upon request from the Company or
   otherwise) to the Holder requesting the registration at the time of a
   request for registration under Section 3, such registration shall not be
   treated as a counted registration for purposes of Section 3(b)(i), even
   though the requesting Holder does not bear the Registration Expenses for
   the registration. All Selling Expenses relating to shares of Holders
   registered under Sections 3, 4 and 6 shall be borne by such Holders pro
   rata on the basis of the numbers of shares so registered on their behalf.

        6.  Registration on Form S-3


   <PAGE>                             7
<PAGE>







            (a)  If the Company has qualified for the use of Form S-3 under
   the Securities Act (which for purposes of this Section 6 shall be deemed
   to include any comparable or successor form or forms), in addition to the
   rights contained in the foregoing provisions of this Agreement, the
   Holders shall have the right to request registrations of their Registrable
   Shares on Form S-3. Such requests must be in writing and must state the
   number of shares of Registrable Shares to be disposed of and the intended
   methods of disposition of such shares by the requesting Holder or Holders.
   The Company shall not be obligated to effect any such registration: (i) if
   the Holders propose to sell less than 200,000 Registrable Shares; or (ii)
   if the Company shall furnish the certification described in Section 3(c)
   (but subject to the limitations set forth therein); or (iii) after the
   Company has previously effected one such registration in any 12-month
   period; or (iv) if the request is made more than five years after the date
   of this Agreement.

            (b)  If a request complying with the requirements of Section 6(a)
   is delivered to the Company, the Company shall use its best efforts to
   cause the Registrable Shares requested to be included in the registration
   to be registered on Form S-3 and to cause such Registrable Shares to be
   registered or qualified under applicable blue sky laws in such
   jurisdictions as the requesting Holders may reasonably request. The
   substantive provisions of Sections 3(a)(i), 3(a)(ii), and 3(c) shall apply
   to such registration. If the registration is for an underwritten offering,
   the substantive provisions of Section 3(e) shall also apply to such
   registration.

        7.  Registration Procedures

        In the case of each registration of Registrable Shares effected by
   the Company pursuant to this Agreement, the Company will keep each
   participating Holder advised in writing as to the initiation of the
   registration and as to the completion thereof. The Company will use its
   best efforts to:

            (a)  Keep the registration effective for a period of 90 days or
   until the participating Holder or Holders have completed the distribution
   described in the registration statement relating thereto, whichever first
   occurs; provided, however, that (i) such 90-day period shall be extended
   for a period of time equal to the period the Holder refrains from selling
   any securities included in such registration at the request of an
   underwriter of the securities of the Company; and (ii) in the case of any
   registration of Registrable Shares on Form S-3 which are intended to be
   offered on a continuous or delayed basis, such 90-day period shall be
   extended, if necessary, to keep the registration statement effective until
   all such Registrable Shares are sold, provided that Rule 145, or any
   successor rule under the Securities Act, permits an offering on a
   continuous or delayed basis, and provided further that applicable rules
   under the Securities Act governing the obligation to file a post-effective
   amendment permit, in lieu of filing a post-effective amendment that (A)
   includes any prospectus required by Section 10(a)(3) of the Securities Act
   or (B) reflects facts or events representing a material or fundamental
   change in the information set forth in the registration statement, the


   <PAGE>                             8
<PAGE>






   incorporation by reference of information required to be included in (A)
   and (B) above to be contained in periodic reports filed pursuant to
   Section 13 or 15(d) of the Exchange Act in the registration statement;

            (b)  Prepare and file with the Commission such amendments and
   supplements to the registration statement and the prospectus used in
   connection with the registration statement as may be necessary to comply
   with the provisions of the Securities Act with respect to the disposition
   of all securities covered by the registration statement;

            (c)  Furnish such number of prospectuses and other documents
   incident thereto, including any amendment of or supplement to the
   prospectus, as a participating Holder from time to time may reasonably
   request;

            (d)  Notify each seller of Registrable Shares covered by the
   registration statement, at any time when a prospectus relating thereto is
   required to be delivered under the Securities Act, of the happening of any
   event as a result of which the prospectus included in the registration
   statement, as then in effect, includes an untrue statement of a material
   fact or omits to state a material fact required to be stated therein or
   necessary to make the statements therein not misleading or incomplete in
   the light of the circumstances then existing, and at the request of any
   such seller prepare and furnish to the seller a reasonable number of
   copies of a supplement to or an amendment of the prospectus as may be
   necessary so that, as thereafter delivered to the purchasers of such
   shares, the prospectus shall not include an untrue statement of a material
   fact or omit to state a material fact required to be stated therein or
   necessary to make the statements therein not misleading or incomplete in
   the light of the circumstances then existing;

            (e)  Cause all Registrable Shares registered pursuant to the
   provisions of this Agreement to be listed on each securities exchange on
   which similar securities issued by the Company are then listed;

            (f)  Provide a transfer agent and registrar for all Registrable
   Shares registered pursuant to such registration statement and a CUSIP
   number for all such Registrable Shares, in each case not later than the
   effective date of the registration; and

            (g)  Otherwise use its best efforts to comply with all applicable
   rules and regulations of the Commission.

        8.  Indemnification

            (a)  The Company will indemnify each Holder, each of its
   officers, directors and partners, legal counsel and accountants and each
   person who controls such Holder within the meaning of Section 15 of the
   Securities Act, with respect to which registration, qualification, or
   compliance has been effected pursuant to this Agreement, and each
   underwriter, if any, and each person who controls within the meaning of
   Section 15 of the Securities Act any underwriter, against all expenses,
   claims, losses, damages and liabilities (or actions, proceedings or
   settlements in respect thereof) arising out of or based on any untrue


   <PAGE>                             9
<PAGE>






   statement (or alleged untrue statement) of a material fact contained in
   any prospectus, offering circular, or other document (including any
   related registration statement, notification, or the like) incident to any
   such registration, qualification or compliance, or based on any omission
   (or alleged omission) to state therein a material fact required to be
   stated therein or necessary to make the statements therein not misleading,
   or any violation by the Company of the Securities Act or any rule or
   regulation thereunder applicable to the Company and relating to action or
   inaction required of the Company in connection with any such registration,
   qualification or compliance, and will reimburse each such Holder, each of
   its officers, directors, partners, legal counsel and accountants, and each
   person controlling such Holder, each such underwriter and each person who
   controls any such underwriter, for any legal and any other expenses
   reasonably incurred in connection with investigating and defending or
   settling any such claim, loss, damage, liability or action, provided that
   the Company will not be liable in any such case to the extent that any
   such claim, loss, damage, liability or expense arises out of or is based
   on any actual or alleged untrue statement or omission that is made in
   reliance upon and in conformity with written information furnished to the
   Company by such Holder, controlling person or underwriter and stated to be
   specifically for use therein. It is agreed that the indemnity agreement
   contained in this Section 8(a) shall not apply to amounts paid in
   settlement of any such loss claim, damage, liability or action if such
   settlement is effected without the consent of the Company (which consent
   has not been unreasonably withheld).

            (b)  Each Holder will, if Registrable Shares held by such Holder
   are included in the securities to which such registration, qualification
   or compliance is being effected, indemnify the Company, each of its
   directors, officers, partners, legal counsel and accountants, each
   underwriter, if any, of the Company s securities covered by such a
   registration statement, each person who controls the Company or such
   underwriter within the meaning of Section 15 of the Securities Act, each
   other such Holder and other stockholder, each of their officers, directors
   and partners, and each person controlling such Holder or other
   stockholder, against all claims, losses, damages and liabilities (or
   actions in respect thereof) arising out of or based on any untrue
   statement (or alleged untrue statement) of a material fact contained in
   any such registration statement, prospectus, offering circular or other
   document, or any omission (or alleged omission) to state therein a
   material fact required to be stated therein or necessary to make the
   statements therein not misleading, and will reimburse the Company and such
   Holders, other stockholders, directors, officers, partners, legal counsel,
   accountants, persons, underwriters or control persons for any legal or any
   other expenses reasonably incurred in connection with investigating or
   defending any such claim, loss, damage, liability or action, in each case
   to the extent, but only to the extent, that such untrue statement (or
   alleged untrue statement) or omission (or alleged omission) is made in
   such registration statement, prospectus, offering circular or other
   document in reliance upon and in conformity with written information
   furnished to the Company by such Holder and stated to be specifically for
   use therein. The obligations of such Holder under this Section 8(b) shall
   not apply to amounts paid in settlement of any such claims, losses,
   damages or liabilities (or actions in respect thereof) if such settlement


   <PAGE>                             10
<PAGE>






   is effected without the consent of such Holder (which consent shall not be
   unreasonably withheld).

            (c)  Each party entitled to indemnification under this Section 8
   (the "Indemnified Party") shall give notice to the party required to
   provide indemnification (the "Indemnifying Party") promptly after such
   Indemnified Party has actual knowledge of any claim to which indemnity may
   be sought, and shall permit the Indemnifying Party to assume the defense
   of any such claim or any litigation resulting therefrom, provided that
   counsel for the Indemnifying Party, who shall conduct the defense of such
   claim or any litigation resulting therefrom, shall be approved by the
   Indemnified Party (whose approval shall not unreasonably be withheld), and
   provided further that the Indemnifying Party shall not assume the defense
   for matters as to which there is a conflict of interest, and provided
   further that the failure of any Indemnified Party to give notice as
   provided herein shall not relieve the Indemnifying Party of its
   obligations under this Section 8, to the extent such failure is not
   materially prejudicial. The Indemnified Party may participate in such
   defense at such party s expense. No Indemnifying Party, in the defense of
   any such claim or litigation, shall, except with the consent of each
   Indemnified Party, consent to entry of any judgment or enter into any
   settlement that does not include as an unconditional term thereof the
   giving by the claimant or plaintiff to such Indemnified Party of a release
   from all liability in respect to such claim or litigation. Each
   Indemnified Party shall furnish such information regarding itself or the
   claim in question as an Indemnifying Party may reasonably request in
   writing and as shall be reasonably required in connection with defense of
   such claim and litigation resulting therefrom.

            (d)  If the indemnification provided for in this Section 8 is
   held by a court of competent jurisdiction to be unavailable to an
   Indemnified Party with respect to any loss, liability, claim, damage or
   expense referred to herein, then the Indemnifying Party, in lieu of
   indemnifying such Indemnified Party hereunder, shall contribute to the
   amount paid or payable by such Indemnified Party as a result of such loss,
   liability, claim, damage or expense in such proportion as is appropriate
   to reflect the relative fault of the Indemnifying Party on the one hand,
   and of the Indemnified Party on the other, in connection with the
   statements or omissions that resulted in such loss, liability, claim,
   damage or expense as well as any other relevant equitable considerations.
   The relative fault of the Indemnifying Party and of the Indemnified Party
   shall be determined by reference to, among other things, whether the
   untrue or alleged untrue statement of a material fact or the omission to
   state a material fact relates to information supplied by the Indemnifying
   Party or by the Indemnified Party and the and Parties  relative intent,
   knowledge, information opportunity to correct or prevent such statement or
   omission.

            (e)  Notwithstanding the foregoing, to the extent that the
   provisions on indemnification and contribution contained in the
   underwriting agreement entered into in connection with an underwritten
   public offering of securities registered under this Agreement are in
   conflict with the foregoing provisions, the provisions in the underwriting
   agreement shall control.


   <PAGE>                             11
<PAGE>






        9.  Information by Holder

        Each Holder of Registrable Shares shall furnish to the Company such
   information regarding such Holder and the distribution proposed by such
   Holder as the Company may reasonably request in writing and as shall be
   reasonably required in connection with any registration, qualification or
   compliance referred to in this Agreement.

       10.  Limitations on Registration of Issues of Securities

       From and after the date of this Agreement, the Company shall not,
   without the prior written consent of the Purchasers, enter into any
   agreement with any holder or prospective holder of any securities of the
   Company giving such holder or prospective holder any registration rights
   the terms of which are more favorable than the registration rights granted
   to the Holders hereunder.

       With a view to making available the benefits of certain rules and
   regulations of the Commission that may permit the sale of the Registrable
   Shares to the public without registration, the Company agrees to use its
   best efforts to:

            (a)  Make and keep public information regarding the Company
   available as those terms are understood and defined in Rule 144 under the
   Securities Act;

            (b)  File with the Commission in a timely manner all reports and
   other documents required of the Company under the Securities Act and the
   Exchange Act;

            (c)  So long as a Holder owns any Registrable Shares, furnish to
   the Holder forthwith upon written request a written statement by the
   Company as to its compliance with the reporting requirements of Rule 144,
   the Securities Act and the Exchange Act, a copy of the most recent annual
   or quarterly report of the Company filed with the Commission, and such
   other reports and documents of the Company and information in its
   possession as a Holder may reasonably request in availing itself of any
   rule or regulation of the Commission allowing a Holder to sell any such
   securities without registration.

       12.  Transfer or Assignment of Registration Rights

       The rights to cause the Company to register securities granted to a
   Holder by the Company under this Agreement may be transferred or assigned
   by the Holder only to a transferee or assignee of not less than 200,000
   shares of Registrable Shares (subject to appropriate adjustments for stock
   splits, stock dividends, reverse stock splits and the like), provided that
   the Company is given written notice at the time of or within a reasonable
   time after the transfer or assignment stating the name and address of the
   transferee or assignee and identifying the securities with respect to
   which such registration rights are being transferred or assigned, and
   provided further that before or concurrently with his or her exercise of
   any such rights the transferee or assignee of such rights assumes in a
   writing given to the Company the obligations of such Holder under this


   <PAGE>                             12
<PAGE>






   Agreement.

       13.  Delay of Registration

       No Holder shall have any right to take any action to restrain, enjoin
   or otherwise delay any registration as the result of any controversy that
   might arise with respect to the interpretation or implementation of this
   Agreement.

       14.  Miscellaneous

            (a)  No Inconsistent Agreements. The Company shall not, on or
   after the date of this Agreement, enter into any agreement with respect to
   its securities which is inconsistent with the rights granted to the
   Holders of the Registrable Shares in this Agreement or otherwise conflicts
   with the provisions hereof.

            (b)  Amendments and Waivers. The provisions of this Agreement,
   including the provisions of this sentence, may not be amended, modified or
   supplemented, and waivers or consents to departures from the provisions
   hereof may not be given, unless by a written instrument signed by an
   officer of the Company and by the Holders of at least a majority of the
   then outstanding Registrable Shares. Notwithstanding the foregoing: (i) in
   no event shall the obligations of any Holder under this Agreement be
   materially increased without the written consent of that Holder; and (ii)
   a waiver or consent to depart from the provisions of this Agreement with
   respect to a matter which relates exclusively to the rights of Holders of
   Registrable Shares whose securities are being sold pursuant to a
   registration statement and which does not directly or indirectly affect
   the rights of Holders of Registrable Shares whose securities are not being
   sold pursuant to the registration statement, may be given by either (A)
   Holders of at least a majority of the then outstanding Registrable Shares
   or (B) Holders of a majority of the Registrable Shares being sold by such
   Holders; provided, however, that the provisions of this sentence may not
   be amended, modified or supplemented except in accordance with the
   provisions of the immediately preceding sentence.

            (c)  Notices. All notices and other communications provided for
   or permitted hereunder shall be made in writing and sent by hand delivery,
   registered first-class mail, courier, telex or telecopier: (i) if to a
   Holder of Registrable Shares, to the most current address of the Holder on
   the books of the Company; and (ii) if to the Company, to the attention of
   its President at the address of its principal executive office. All such
   notices and communications shall be deemed to have been given: when
   delivered at the proper address, if personally delivered or delivered by
   courier; five business days after being deposited in the mail, postage
   prepaid, if mailed by registered first-class mail; and when answered back,
   if telexed, telecopied or sent by similar facsimile transmission.

            (d)  Successors and Assigns. Subject to Sections 8 and 12, this
   Agreement shall inure to the benefit of and be binding upon the successors
   and assigns of each of the parties.

            (e)  Counterparts. This Agreement may be executed in any number


   <PAGE>                             13
<PAGE>






   of counterparts and by the parties hereto in separate counterparts, each
   of which when so executed shall be deemed to be an original and all of
   which taken together shall constitute one and the same agreement.

            (f)  Headings and Section References. The headings in this
   Agreement are for convenience of reference only and shall not limit or
   otherwise affect the meaning hereof. Unless otherwise indicated, each
   reference to a Section shall refer to a Section of this Agreement.

            (g)  Governing Law. This Agreement shall be governed by and
   construed in accordance with the laws of the State of New York, as applied
   to contracts made and performed in California, without regard to
   principles of conflict of laws.

            (h)  Severability. If any term, provision, covenant or
   restriction of this Agreement is held by a court of competent jurisdiction
   to be invalid, void or unenforceable, the remainder of the terms,
   provisions, covenants and restrictions set forth herein shall remain in
   full force and effect and shall in no way be affected, impaired or

   or any interest therein which the Company in good faith believes violates
   the restrictions set forth  herein.

             (c)  Unless registered under the Securities Act, any proposed
   offer, sale, transfer, pledge or other disposition during the Restricted
   Period of any of the Securities or any interest therein shall be subject
   to the condition that Purchaser must deliver to the Company (i) a written
   certification that neither record nor beneficial ownership of the
   Securities has been offered or sold in the United States or to, or for the
   account or benefit of, any "U.S. person" (as defined in Regulation S),

   of which is attached hereto as Exhibit "A" and incorporated herein by this
   reference.

        (u)  "ULTRA" shall mean ULTRA PACIFIC HOLDINGS S.A., a Liberian
   corporation.
   2.   Conditions Upon Which Registration Rights Are Triggered.

        If at any time the registration rights under the Sundial/Ultra
   Registration Rights Agreement are triggered, Ultra shall have Piggyback
   Registration Rights to participate in any registration initiated
   thereunder and to include the Registrable Shares with the shares for which
   the registration is filed pursuant the Sundial/Ultra Registration Rights
   Agreement.  

   3.   Expenses of Registration

        All Registration Expenses incurred in connection with any
   registration, qualification or compliance pursuant to Section 2 shall be
   borne in accordance with the provisions of Section 5 of the Sundial/Ultra
   Registration Rights Agreement.

   4.   Participation Registration

        (a)  Registration Right.  If the conditions set forth in Section 2
   above apply and, after the date of this Agreement, the Company shall
   determine to register any of its securities either for its own account or
   the account of a security holder or holders (other than pursuant to
   Section 3 or 6), except for a registration relating solely to employee
   benefit plans, a registration relating solely to a Rule 145 transaction, a
   registration on any registration form that would not permit secondary
   sales of Registrable Shares or a registration filed more than five years
   after the date of this Agreement, the Company  will, in two such
   instances:

             (i)  Promptly give to each Holder written notice thereof;


             (ii) Use its best efforts to include in such registration (and
   any related qualification under blue sky laws or other compliance), except
   as set forth in Section 4(b) below, and in any underwriting involved
   therein, all the Registrable Shares specified in a written request or
   requests made by any Holder within 15 days after the written notice from
   the Company described in clause (i) above is given to that Holder.  Such
   written request may specify all or a part of a Holder's Registrable
   Shares.

        (b)  Underwritten Offering.   If the registration of which the
   Company gives notice under Section 4(a) is for a registered public
   offering involving an underwriting, the Company shall so advise the
   Holders as a part of the written notice given pursuant to Section 4(a)(i). 
   In such event, the right of any Holder to registration pursuant to this
   Section 4 shall be conditioned upon such Holder's participation in such
   underwriting and the inclusion of such Holder's Registrable Shares in the
   underwriting to the extent provided herein. All Holders proposing to


   <PAGE>                             3
<PAGE>






   distribute their securities through the underwriting shall (together with
   the Company and any other persons proposing to distribute their securities
   through the underwriting) enter into an underwriting agreement in
   customary form with the representative of the underwriter(s) selected by
   the Company.  Notwithstanding any other provision of this Section 4, if
   the representative of the underwriter(s) advises the Company in writing
   that marketing factors require a limitation on the number of shares to be
   underwritten, the representative may (subject to the limitations set forth
   below) limit the number of Registrable Shares to be included in the
   registration and underwriting; provided that the value of the included
   Registrable Shares shall be at least 20% of the total value of the
   securities included in the registration.  The Company shall so advise all
   Holders requesting to participate in the registration and the number of
   shares that may be included in the registration and underwriting shall be
   allocated: first, to the Company for securities being sold for its own
   account; second, among Registrable Shares held by all Holders who have
   requested inclusion in the registration in proportion, as nearly as
   practicable, to the respective amounts of Registrable Shares held by such
   Holders and properly requested to be included at the time of filing the
   registration statement; and then to shares being sold for the accounts of
   other Persons.  Any Registrable Shares so excluded from the underwriting
   by reason of the representative's limitation shall be withdrawn from such
   registration. To facilitate the allocation of shares in accordance with
   the above provisions, the Company or the representative of underwriter(s)
   may round the number of shares allocated to any Holder or other
   shareholder to the nearest 100 shares. If a Holder who has requested
   inclusion in the registration does not agree to the terms of the
   underwriting, that Holder's shares may be excluded from the underwriting
   by written notice from the Company or the representative of the
   underwriter(s) and the shares so excluded shall be withdrawn from the
   registration.  If shares are so excluded from the underwriting because of
   a failure to agree to its terms and the number of shares of Registrable
   Shares to be included in the underwriting was previously reduced as a
   result of marketing factors pursuant to this Section 4(b), then, with the
   permission of the representative of the underwriter(s) the Company shall
   offer to all Holders who have retained rights to include Registrable
   Shares in the underwriting the right to include additional Registrable
   Shares in an aggregate amount equal to the number of shares so excluded. 
   The registration of such additional Registrable Shares shall be allocated
   among the Holders requesting the additional inclusion pro rata in
   accordance with the numbers of their Registrable Shares which are
   otherwise to be included in the registration.

        (c)  Right to Terminate Registration.  The Company shall have the
   right to terminate or withdraw any registration initiated by it under this
   Section 4 prior to the registration's effectiveness, whether or not any
   Holder has elected under this Section 4 to include shares in the
   registration.

   5.   Expenses of Registration

        All Registration Expenses incurred in connection with any
   registration, qualification or compliance pursuant to Sections 3 and 4
   shall be borne by the Company. All Registration Expenses incurred in


   <PAGE>                             4
<PAGE>






   connection with the registration of Registrable Shares under Section 6
   shall be borne by the Holders participating in the registration pro rata
   on the basis of the numbers of Registrable Shares so registered on their
   behalf, provided that, if other shares are included in the registration,
   the Registration Expenses shall be reasonably allocated among the Holders,
   the Company and other participating shareholders based on the numbers of
   their shares that are registered.  A Holder or Holders may elect to bear
   without reimbursement by the Company the Registration Expenses for a
   Demand Registration proceeding begun by them pursuant to Section 3 and
   subsequently withdrawn by them. In such a case, the registration
   proceeding shall not be counted for purposes of Section 3(b)(ii).  If a
   withdrawal of a Demand Registration by a Holder is based upon material
   adverse information relating to the Company that is different from the
   information known or available (upon request from the Company or
   otherwise) to the Holder requesting the registration at the time of a
   request for registration under Section 3, such registration shall not be
   treated as a counted registration for purposes of Section 3(b)(i), even
   though the requesting Holder does not bear the Registration Expenses for
   the registration.  All Selling Expenses relating to shares of Holders
   registered under Sections 3, 4 and 6 shall be borne by such Holders pro
   rata on the basis of the numbers of shares so registered on their behalf.

   6.   Registration on Form S-3

        (a)  If the Company has qualified for the use of Form S-3 under the
   Securities Act (which for purposes of this Section 6 shall be deemed to
   include any comparable or successor form or forms), in addition to the
   rights contained in the foregoing provisions of this Agreement, the
   Holders shall have the right to request registrations of their Registrable
   Shares on Form S-3.  Such requests must be in writing and must state the
   number of shares of Registrable Shares to be disposed of and the intended
   methods of disposition of such shares by the requesting Holder or Holders.
   The Company shall not be obligated to effect any such registration: (i) if
   the Holders propose to sell less than 200,000 Registrable Shares; or (ii)
   if the Company shall furnish the certification described in Section 3(c)
   (but subject to the limitations set forth therein); or (iii) after the
   Company has previously effected one such registration in any 12-month
   period; or (iv) if the request is made more than five years after the date
   of this Agreement. 

        (b)  If a request complying with the requirements of Section 6(a) is
   delivered to the Company, the Company shall use its best efforts to cause
   the Registrable Shares requested to be included in the registration to be
   registered on Form S-3 and to cause such Registrable Shares to be
   registered or qualified under applicable blue sky laws in such
   jurisdictions as the requesting Holders may reasonably request. The
   substantive provisions of Sections 3(a)(i), 3(a)(ii), and 3(c) shall apply
   to such registration. If the registration is for an underwritten offering,
   the substantive provisions of Section 3(e) shall also apply to such
   registration.

   7.   Registration Procedures

        In the case of each registration of Registrable Shares effected by


   <PAGE>                             5
<PAGE>






   the Company pursuant to this Agreement, the Company will keep each
   participating Holder advised in writing as to the initiation of the
   registration and as to the completion thereof.  The Company will use its
   best efforts to:

        (a)  Keep the registration effective for a period of 90 days or until
   the participating Holder or Holders have completed the distribution
   described in the registration statement relating thereto, whichever first
   occurs; provided, however, that (i) such 90-day period shall be extended
   for a period of time equal to the period the Holder refrains from selling
   any securities included in such registration at the request of an
   underwriter of the securities of the Company; and (ii) in the case of any
   registration of Registrable Shares on Form S-3 which are intended to be
   offered on a continuous or delayed basis, such 90-day period shall be
   extended, if necessary, to keep the registration statement effective until
   all such Registrable Shares are sold, provided that Rule 145, or any
   successor rule under the Securities Act, permits an offering on a
   continuous or delayed basis, and provided further that applicable rules
   under the Securities Act governing the obligation to file a post-effective
   amendment permit, in lieu of filing a post-effective amendment that (A)
   includes any prospectus required by Section 10(a)(3) of the Securities Act
   or (B) reflects facts or events representing a material or fundamental
   change in the information set forth in the registration statement, the
   incorporation by reference of information required to be included in (A)
   and (B) above to be contained in periodic reports filed pursuant to
   Section 13 or 15(d) of the Exchange Act in the registration statement;

        (b)  Prepare and file with the Commission such amendments and
   supplements to the registration statement and the prospectus used in
   connection with the registration statement as may be necessary to comply
   with the provisions of the Securities Act with respect to the disposition
   of all securities covered by the registration statement;

        (c)  Furnish such number of prospectuses and other documents incident
   thereto, including any amendment of or supplement to the prospectus, as a
   participating Holder from time to time may reasonably request;

        (d)  Notify each seller of Registrable Shares covered by the
   registration statement, at any time when a prospectus relating thereto is
   required to be delivered under the Securities Act, of the happening of any
   event as a result of which the prospectus included in the registration
   statement, as then in effect, includes an untrue statement of a material
   fact or omits to state a material fact required to be stated therein or
   necessary to make the statements therein not misleading or incomplete in
   the light of the circumstances then existing, and at the request of any
   such seller prepare and furnish to the seller a reasonable number of
   copies of a supplement to or an amendment of the prospectus as may be
   necessary so that, as thereafter delivered to the purchasers of such
   shares, the prospectus shall not include an untrue statement of a material
   fact or omit to state a material fact required to be stated therein or
   necessary to make the statements therein not misleading or incomplete in
   the light of the circumstances then existing;

        (e)  Cause all Registrable Shares registered pursuant to the


   <PAGE>                             6
<PAGE>






   provisions of this Agreement to be listed on each securities exchange on
   which similar securities issued by the Company are then listed;

        (f)  Provide a transfer agent and registrar for all Registrable
   Shares registered pursuant to such registration statement and a CUSIP
   number for all such Registrable Shares, in each case not later than the
   effective date of the registration; and

        (g)  Otherwise use its best efforts to comply with all applicable
   rules and regulations of the Commission.

   8.   Indemnification

        (a)  The Company will indemnify each Holder, each of its officers,
   directors and partners, legal counsel and accountants and each person who
   controls such Holder within the meaning of Section 15 of the Securities
   Act, with respect to which
   registration, qualification, or compliance has been effected pursuant to
   this Agreement, and each underwriter, if any, and each person who controls
   within the meaning of Section 15 of the Securities Act any underwriter,
   against all expenses, claims, losses, damages and liabilities (or actions,
   proceedings or settlements in respect thereof) arising out of or based on
   any untrue statement (or alleged untrue statement) of a material fact
   contained in any prospectus, offering circular, or other document
   (including any related registration statement, notification, or the like)
   incident to any such registration, qualification or compliance, or based
   on any omission (or alleged omission) to state therein a material fact
   required to be stated therein or necessary to make the statements therein
   not misleading, or any violation by the Company of the Securities Act or
   any rule or regulation thereunder applicable to the Company and relating
   to action or inaction required of the Company in connection with any such
   registration, qualification or compliance, and will reimburse each such
   Holder, each of its officers, directors, partners, legal counsel and
   accountants, and each person controlling such Holder, each such
   underwriter and each person who controls any such underwriter, for any
   legal and any other expenses reasonably incurred in connection with
   investigating and defending or settling any such claim, loss, damage,
   liability or action, provided that the Company will not be liable in any
   such case to the extent that any such claim, loss, damage, liability or
   expense arises out of or is based on any actual or alleged untrue
   statement or omission that is made in reliance upon and in conformity with
   written information furnished to the Company by such Holder, controlling
   person or underwriter and stated to be specifically for use therein. It is
   agreed that the indemnity agreement contained in this Section 8(a) shall
   not apply to amounts paid in settlement of any such loss claim, damage,
   liability or action if such settlement is effected without the consent of
   the Company (which consent has not been unreasonably withheld).

        (b)  Each Holder will, if Registrable Shares held by such Holder are
   included in the securities to which such registration, qualification or
   compliance is being effected, indemnify the Company, each of its
   directors, officers, partners, legal counsel and accountants, each
   underwriter, if any, of the Company's securities covered by such a
   registration statement, each person who controls the Company or such


   <PAGE>                             7
<PAGE>






   underwriter within the meaning of Section 15 of the Securities Act, each
   other such Holder and other stockholder, each of their officers, directors
   and partners, and each person controlling such Holder or other
   stockholder, against all claims, losses, damages and liabilities (or
   actions in respect thereof) arising out of or based on any untrue
   statement (or alleged untrue statement) of a material fact contained in
   any such registration statement, prospectus, offering circular or other
   document, or any omission (or alleged omission) to state therein a
   material fact required to be stated therein or necessary to make the
   statements therein not misleading, and will reimburse the Company and such
   Holders, other stockholders, directors, officers, partners, legal counsel,
   accountants, persons, underwriters or control persons for any legal or any
   other expenses reasonably incurred in connection with investigating or
   defending any such claim, loss, damage, liability or action, in each case
   to the extent, but only to the extent, that such untrue statement (or
   alleged untrue statement) or omission (or alleged omission) is made in
   such registration statement, prospectus, offering circular or other
   document in reliance upon and in conformity with written information
   furnished to the Company by such Holder and stated to be specifically for
   use therein. The obligations of such Holder under this Section 8(b) shall
   not apply to amounts paid in settlement of any such claims, losses,
   damages or liabilities (or actions in respect thereof) if such settlement
   is effected without the consent of such Holder (which consent shall no be
   unreasonably withheld).

        (c)  Each party entitled to indemnification under this Section 8 (the
   "Indemnified Party") shall give notice to the party required to provide
   indemnification (the "Indemnifying Party") promptly after such Indemnified
   Party has actual knowledge of any claim to which indemnity may be sought,
   and shall permit the Indemnifying Party to assume the defense of any such
   claim or any litigation resulting therefrom, provided that counsel for the
   Indemnifying Party, who shall conduct the defense of such claim or any
   litigation resulting therefrom, shall be approved by the Indemnified Party
   (whose approval shall not unreasonably be withheld), and provided further
   that the Indemnifying Party shall not assume the defense for matters as to
   which there is a conflict of interest, and provided further that the
   failure of any Indemnified Party to give notice as provided herein shall
   not relieve the Indemnifying Party of its obligations under this Section
   8, to the extent such failure is not materially prejudicial. The
   Indemnified Party may participate in such defense at such party's expense.
   No Indemnifying Party, in the defense of any such claim or litigation,
   shall, except with the consent of each Indemnified Party, consent to entry
   of any judgment or enter into any settlement that does not include as an
   unconditional term thereof the giving by the claimant or plaintiff to such
   Indemnified Party of a release from all liability in respect to such claim
   or litigation.  Each Indemnified Party shall furnish such information
   regarding itself or the claim in question as an Indemnifying Party may
   reasonably request in writing and as shall be reasonably required in
   connection with defense of such claim and litigation resulting therefrom.

        (d)  If the indemnification provided for in this Section 8 is held by
   a court of competent jurisdiction to be unavailable to an Indemnified
   Party with respect to any loss, liability, claim, damage or expense
   referred to herein, then the Indemnifying Party, in lieu of indemnifying


   <PAGE>                             8
<PAGE>






   such Indemnified Party hereunder, shall contribute to the amount paid or
   payable by such Indemnified Party as a result of such loss, liability,
   claim, damage or expense in such proportion as is appropriate to reflect
   the relative fault of the Indemnifying Party on the one hand, and of the
   Indemnified Party on the other, in connection with the statements or
   omissions that resulted in such loss, liability, claim, damage or expense
   as well as any other relevant equitable considerations. The relative fault
   of the Indemnifying Party and of the Indemnified Party shall be determined
   by reference to, among other things, whether the untrue or alleged untrue
   statement of a material fact or the omission to state a material fact
   relates to information supplied by the Indemnifying Party or by the
   Indemnified Party and the and Parties'  relative intent,  knowledge,
   information opportunity to correct or prevent such statement or omission.

        (e)  Notwithstanding the foregoing, to the extent that the provisions
   on indemnification and contribution contained in the underwriting
   agreement entered into in connection with an underwritten public offering
   of securities registered under this Agreement are in conflict with the
   foregoing provisions, the provisions in the underwriting agreement shall
   control.

   9.   Information by Holder

        Each Holder of Registrable Shares shall furnish to the Company such
   information regarding such Holder and the distribution proposed by such
   Holder as the Company may reasonably request in writing and as shall be
   reasonably required in connection with any registration, qualification or
   compliance referred to in this Agreement. 

   10.   Limitations on Registration of Issues of Securities

        From and after the date of this Agreement, the Company shall not,
   without the prior written consent of the Purchasers, enter into any
   agreement with any holder or prospective holder of any securities of the
   Company giving such holder or prospective holder any registration rights
   the terms of which are more favorable than the registration rights granted
   to the Holders hereunder.

   11.   Rule 144 Reporting

        With a view to making available the benefits of certain rules and
   regulations of the Commission that may permit the sale of the Registrable
   Shares to the public without registration, the Company agrees to use its
   best efforts to:

        (a)  Make and keep public information regarding the Company available
   as those terms are understood and defined in Rule 144 under the Securities
   Act;

        (b)  File with the Commission in a timely manner all reports and
   other documents required of the Company under the Securities Act and the
   Exchange Act;

   as to its compliance with the reporting requirements of Rule 144, the
   Securities Act and the Exchange Act, a copy of the most recent annual or
   quarterly report of the Company filed with the Commission, and such other
   reports and documents of the Company and information in its possession as
   a Holder may reasonably request in availing itself of any rule or
   regulation of the Commission allowing a Holder to sell any such securities
   without registration.

   12.  Transfer or Assignment of Registration Rights

        The rights to cause the Company to register securities granted to a
   Holder by the Company under this Agreement may be transferred or assigned
   by the Holder only to a transferee or assignee of not less than 200,000
   shares of Registrable Shares (subject to appropriate adjustments for stock
   splits, stock dividends, reverse stock splits and the like), provided that
   the Company is given written notice at the time of or within a reasonable
   time after the transfer or assignment stating the name and address of the
   transferee or assignee and identifying the securities with respect to
   which such registration rights are being transferred or assigned, and
   provided further that before or concurrently with his or her exercise of
   any such rights the transferee or assignee of such rights assumes in a
   writing given to the Company the obligations of such Holder under this
   Agreement.

   13.  Delay of Registration

   might arise with respect to the interpretation or implementation of this
   Agreement.

   14.  Miscellaneous

        (a)  No Inconsistent Agreements.  The Company shall not, on or after
   the date of this Agreement, enter into any agreement with respect to its

   a waiver or consent to depart from the provisions of this Agreement with
   respect to a matter which relates exclusively to the rights of Holders of
   Registrable Shares whose securities are being sold pursuant to a
   registration statement and which does not directly or indirectly affect
   the rights of Holders of Registrable Shares whose securities are not being
   sold pursuant to the registration statement, may be given by either (A)
   Holders of at least a majority of the then outstanding Registrable Shares
   or (B) Holders of a majority of the Registrable Shares being sold by such
   Holders; provided, however, that the provisions of this sentence may not

   the books of the Company; and (ii) if to the Company, to the attention of
   its President at the address of its principal executive office. All such
   notices and communications shall be deemed to have been given: when
   delivered at the proper address, if personally delivered or delivered by
   courier; five business days after being deposited in the mail, postage
   prepaid, if mailed by registered first-class mail; and when answered back,
   if telexed, telecopied or sent by similar facsimile transmission.

        (d)  Successors and Assigns.  Subject to Sections 8 and 12, this
   Agreement shall inure to the benefit of and be binding upon the successors
   and assigns of each of the parties.

        (e)  Counterparts.  This Agreement may be executed in any number of

   affect the meaning hereof. Unless otherwise indicated, each reference to a
   Section shall refer to a Section of this Agreement.

   construed in accordance with the laws of the State of New York, as applied

   this Agreement is held by a court of competent jurisdiction to be invalid,
   void or unenforceable, the remainder of the terms, provisions, covenants
   and restrictions set forth herein shall remain in full force and effect
   and shall in no way be affected, impaired or invalidated, and the parties
   hereto shall use their best efforts to find and employ an alternative
   means to achieve the same or substantially the same result as that
   contemplated by such term, provision, covenant or restriction.

        (i)  Entire Agreement.  This Agreement is intended by the parties as
   a complete and final expression of their agreement with respect of the

   Agreement)  a  security  interest in the Collateral (as defined below), as
   more fully set forth herein;

             NOW, THEREFORE, in consideration of the foregoing and other good
   and  valuable  consideration, receipt of which is hereby acknowledged, the

   Pledgor,  endorsed or assigned in blank or in favor of the Agent, and (ii)
   upon the occurrence and during the continuation of an Event of Default, to
   exchange  the  certificates or other instruments or documents representing
   the Collateral for certificates of smaller or larger denominations for any
   purpose consistent with this Pledge Agreement.

                5.  Representations, Warranties and Covenants of the Pledgor.

                   5.1  the Pledgor is duly organized and validly existing in
   good  standing  under  the  laws  of  the State of Delaware and is in good
   standing as a foreign corporation in all jurisdictions where the nature of
   its  properties  or business requires it to be qualified.  The Pledgor has
   the corporate power to own its properties and carry on its business as now

   this Pledge Agreement and to pledge to the Agent and to grant to the Agent
   a security interest in the Collateral;

                  5.2  the execution, delivery and performance of this Pledge
   Agreement  and  the  pledge  to  the Agent and the grant to the Agent of a
   security  interest  in the Collateral (i) have been duly authorized by all
   necessary  corporate  action  on  the  part  of the Pledgor, (ii) will not

<PAGE>




   authority  or  any  judgment of any court applicable to the Pledgor or its
   properties  and  assets,  (iii)  will  not  violate  any  provision of the
   Certificate  of  Incorporation or By-Laws of the Pledgor or any indenture,
   any  agreement  for  borrowed  money,  any  bond,  note  or  other similar
   instrument or any other material agreement to which the Pledgor is a party
   or  by which the Pledgor or any of its property is bound or affected, (iv)
   will  not  be  in conflict with, result in a breach of or constitute (with
   due  notice  or lapse of time or both) a default under any such indenture,
   agreement  for  borrowed money, bond, note, instrument or other agreement,
   and (v) will not result in the creation, or imposition of any lien, charge
   or encumbrance of any nature whatsoever upon any property or assets of the
   Pledgor other than pursuant to this Pledge Agreement;

                  5.3  this Pledge Agreement constitutes the legal, valid and
   binding  obligation  of  the  Pledgor,  enforceable in accordance with its
   terms,  subject  (i)  as  to  the  enforcement  of remedies, to applicable
   bankruptcy,  reorganization, insolvency and other laws affecting creditors
   rights  generally  and to moratorium laws from time to time in effect, and
   (ii) to general equitable principles;

                  5.4  the Pledged Securities represent all of the issued and
   outstanding  shares  of  the  capital stock of MIC, all of which are owned
   beneficially and of record by the Pledgor;

                 5.5  the Pledgor has good title to the Collateral;

                       5.6  the Collateral is not subject to any other liens,
   security interests or encumbrances;

                    5.7  the Pledgor has the right to pledge and to grant the
   security  interest in the Collateral free of any encumbrances, and without
   the  consent  of  the  creditors of the Pledgor or any other person or any
   governmental authority whatsoever;

                      5.8  there is no material pending legal or governmental
   proceeding  to  which  the  Pledgor  is  a  party  or  to which any of its
   properties  is  subject,  which  proceeding will materially affect (i) the
   Pledgor  s  ability  to  perform  its  obligations  hereunder  or (ii) the
   Collateral;

                   5.9  this Pledge Agreement creates in favor of the Agent a
   valid,  binding  and  enforceable security interest in, and lien upon, all
   right,  title  and  interest  of  the  Pledgor in the Collateral and, upon
   delivery  of  the  Collateral  to  the  Agent, the Agent will have a fully
   perfected  first  and  prior security interest in and lien upon all right,
   title and interest of the Pledgor in the Collateral; and

                     5.10  the Pledgor will not create or permit to exist any
   lien,  security  interest  or  encumbrance  on  the  Collateral  except as
   permitted by this Agreement.

             6.  Voting Rights; Dividends; Etc.

                   6.1  The Pledgor shall be entitled to exercise any and all
   voting  and/or  consensual  rights  and  powers  accruing to owners of the
   Pledged  Securities  or  any part thereof for any purpose not inconsistent


   <PAGE>                             3
<PAGE>




   with  the  terms  hereof,  at  all  times, except as expressly provided in
   Section 6.3 below.

                   6.2  Any dividends or distributions of any kind whatsoever
   (in  cash  or  otherwise)  received  by the Pledgor, whether declared on a
   regular,  periodic  basis or resulting from a subdivision, combination, or
   reclassification  of  the  outstanding  capital  stock  of  the issuer, in
   respect of the Pledged Securities, or received in exchange for the Pledged
   Securities,  or other Collateral or any part thereof or as a result of any
   merger,  consolidation,  acquisition, or other exchange of assets to which
   the  issuer may be a party, or otherwise, shall, be and become part of the
   Collateral  pledged  hereunder  and  shall immediately be delivered to the
   Agent to be held subject to the terms hereof.

                    6.3  Upon the occurrence and during the continuance of an
   Event  of Default, all rights of the Pledgor to exercise the voting and/or
   consensual  rights and powers which it is entitled to exercise pursuant to
   Section 6.1 shall cease, and all such rights shall thereupon become vested
   in  the Agent, which shall have the sole and exclusive right and authority
   to exercise such voting and/or consensual rights and powers.

             7.  Remedies Upon Default. 

                       7.1  If an Event of Default shall have occurred and be
   continuing,  the  Agent  may  sell the Collateral, or any part thereof, at
   public  or  private  sale  or  at  any broker s board or on any securities
   exchange,  for cash, upon credit or for future delivery as the Agent shall
   deem  appropriate  subject to the terms hereof or as otherwise provided in
   the  New  York  Uniform Commercial Code.  The Agent shall be authorized at
   any  such sale (if it deems it advisable so to do) to restrict to the full
   extent  permitted  by applicable law the prospective bidders or purchasers
   to  persons  who  will  represent  and  agree that they are purchasing the
   Collateral for their own account for investment and not with a view to the
   distribution  or  sale thereof, and upon consummation of any such sale the
   Agent  shall  have  the  right  to  assign,  transfer,  and deliver to the
   purchaser  or  purchasers  thereof  the  Collateral  so  sold.   Each such
   purchaser  at  any such sale shall hold the property sold absolutely, free
   from any claim or right on the part of the Pledgor.

                      7.2  The Agent shall give the Pledgor ten calendar days
   written  notice  of its intention to make any such public or private sale,
   or  sale  at  any broker s board or on any such securities exchange, or of
   any  other  disposition  of  the  Collateral.  Such notice, in the case of
   public sale, shall state the time and place for such sale and, in the case
   of  sale  at a broker s board or on a securities exchange, shall state the
   board  or  exchange  at which such sale is to be made and the day on which
   the Collateral, or portion thereof, will first be offered for sale at such
   board  or  exchange.    Any such public sale shall be held at such time or
   times  within  ordinary  business hours and at such place or places as the
   Agent  may  fix  and  shall state in the notice of such sale.  At any such
   sale,  the  Collateral,  or portion thereof, to be sold may be sold in one
   lot  as  an entirety or in separate parcels, as the Agent may (in its sole
   and  absolute  discretion) determine.  The Agent shall not be obligated to
   make  any  sale  of  the  Collateral  if  it shall determine not to do so,
   regardless of the fact that notice of sale of the Collateral may have been
   given.    The Agent may, without notice or publication, adjourn any public


   <PAGE>                             4
<PAGE>




   or  private  sale  or  cause the same to be adjourned from time to time by
   announcement  at  the  time  and  place fixed for sale, and such sale may,
   without  further  notice,  be made at the time and place to which the same
   was  so  adjourned.  In case the sale of all or any part of the Collateral
   is  made on credit or for future delivery, the Collateral so sold shall be
   retained  by  the  Agent  until the sale price is paid by the purchaser or
   purchasers  thereof,  but  the Agent shall not incur any liability in case
   any  such  purchaser  or  purchasers shall fail to take up and pay for the
   Collateral  so  sold and, in case of any such failure, such Collateral may
   be  sold  again  upon  like notice.  At any sale or sales made pursuant to
   this  Section 7, the Agent may bid for or purchase, free from any claim or
   right  of  whatsoever  kind,  including  any  equity of redemption, of the
   Pledgor,  any  such  demand,  notice,  claim, right or equity being hereby
   expressly  waived  and  released, any or all of the Collateral offered for
   sale,  and  may make any payment on the account thereof by using any claim
   for  moneys  then  due  and  payable to the Purchasers by the Pledgor as a
   credit against the purchase price; and the Agent, upon compliance with the
   terms  of  sale,  may  hold,  retain and dispose of the Collateral without
   further  accountability  therefor to the Pledgor or any, third party.  The
   Agent  shall  in  any such sale make no representations or warranties with
   respect  to the Collateral or any part thereof and shall not be chargeable
   with  any  of  the  obligations or liabilities of the Pledgor with respect
   thereto.    As  an  alternative  to  exercising  the  power of sale herein
   conferred  upon  it, the Agent may proceed by a suit or suits at law or in
   equity to foreclose upon the Collateral under this Pledge Agreement and to
   sell  the  Collateral,  or  any portion thereof, pursuant to a judgment or
   decree of a court or courts having competent jurisdiction.

                8.  Application of Proceeds of Sale.  The proceeds of sale of
   the  Collateral  sold pursuant to Section 7 hereof shall be distributed by
   the Agent (after deduction of all costs and expenses incurred by the Agent
   while  enforcing  its rights pursuant to this Pledge Agreement, including,
   without limitation, reasonable attorneys  fees and expenses) to the holder
   of the Note, to be applied by the holder to the Obligations in such manner
   as it may deem appropriate.

                9.  Agent Appointed Attorney-in-Fact. Upon the occurrence and
   during the continuance of an Event of Default, the Pledgor hereby appoints
   the  Agent  its  attorney-in-fact  for  the  purpose  of  carrying out the
   provisions  of this Pledge Agreement and the pledge of, and the grant of a
   security  interest  in,  the  Collateral  hereunder  and the taking of any
   action  and  the  execution  of    any instrument which the Agent may deem
   n e c essary  or  advisable  to  accomplish  the  purposes  hereof,  which
   appointment is irrevocable and coupled with an interest.  Without limiting
   the  generality of the foregoing, the Agent shall have the right and power
   to  receive,  endorse  and  collect  all  checks  and other orders for the
   payment  of money made payable to the Pledgor representing any dividend or
   other  distribution  payable  in  respect  of  the  Collateral or any part
   thereof and to give full discharge for the same.

                10.  Federal Securities Laws.  In view of the position of the
   Pledgor  in  relation  to  the  Collateral, or because of other present or
   future  circumstances,  a  question  may arise under the Securities Act of
   1933,  as  amended,  as now or hereafter in effect, or any similar statute
   hereafter  enacted  analogous  in purpose or effect (such Act and any such
   similar  statute  as  from time to time in effect being hereinafter called


   <PAGE>                             5
<PAGE>




   the  "Federal  Securities  Laws"),  with respect to any disposition of the
   Collateral  permitted  hereunder.  The Pledgor understands that compliance
   with  the  Federal  Securities  Laws may very strictly limit the course of
   conduct of the Agent if the Agent were to attempt to dispose of all or any
   part  of  the  Collateral,  and  may also limit the extent to which or the
   manner in which any subsequent transferee of any Collateral may dispose of
   the same.  Similarly, there may be other legal restrictions or limitations
   affecting  the  Agent  in any attempt to dispose of all or any part of the
   Collateral  under  applicable  blue sky or other state securities laws, or
   similar laws analogous in purpose or effect.  Under applicable law, in the
   absence  of an agreement to the contrary, the Agent may perhaps be held to
   have  certain  general  duties and obligations to the Pledgor to make some
   effort  towards  obtaining a fair price even though the Obligations may be
   discharged  or  reduced  by the proceeds of a sale at a lesser price.  The
   Pledgor clearly understands that the Agent is not to have any such general
   duty  or  obligation  to  it, and the Pledgor will not attempt to hold the
   Agent  responsible  for  selling  all  or any part of the Collateral at an
   inadequate  price, even if the Agent shall accept the first offer received
   or  does  not approach more than one possible purchaser.  Without limiting
   the  generality  of the foregoing, the provisions of this Section 10 would
   apply  if,  for  example,  the  Agent were to place all or any part of the
   Collateral for private placement by an investment banking firm, or if such
   investment  banking  firm  purchased all or any part of the Collateral for
   its  own account, or if the Agent placed all or any part of the Collateral
   privately with a purchaser or purchasers.

                   11.  Financing Statements.  So long as the Obligations are
   outstanding  and the security interest hereunder shall not have terminated
   in  accordance  with  Section 13 hereof, the Pledgor agrees to execute and
   deliver  to  the  Agent  such  UCC financing statements and any amendments
   thereto  or  continuations  thereof and any other documents or instruments
   and  to  give such notices as the Agent may deem necessary or desirable to
   perfect  the lien of the Agent on the Collateral.  If the Pledgor does not
   execute  and  deliver to the Agent any such financing statement, amendment
   or  other  document or instrument or give such notice within five calendar
   days  after  requested  by  the  Agent,  then  the Secured Party is hereby
   authorized  by the Pledgor to file such items or give such notice, without
   the  signature of the Pledgor or to execute such items as attorney-in-fact
   for  the  Pledgor.    The  Pledgor  further authorizes the Agent, upon the
   occurrence  and  during the continuation of an Event of Default, to notify
   any  obligors on instruments that all sums payable to the Pledgor relating
   to the collateral shall be paid directly to the Agent.

                 12.  Further Assurances.  Upon the request of the Agent, the
   Pledgor  hereby  agrees  duly  to execute and deliver, or cause to be duly
   executed  and delivered, from time to time, at the cost and expense of the
   Pledgor,  such  further  instruments as may be necessary or proper, in the
   reasonable judgment of the Agent, to carry out the provisions and purposes
   of  this  Pledge Agreement and to do all things necessary or advisable, in
   the  judgment  of  the  Agent,  to perfect and preserve the pledge and the
   security  interests  of  the  Agent hereunder and in the Collateral or any
   portion thereof.

             13.  Release of Collateral. 

                  13.1   The pledge and grant of the security interest in all


   <PAGE>                             6
<PAGE>




   of  the  Collateral  hereunder shall terminate upon payment in full of the
   Obligations  or conversion, redemption or prepayment in full of all of the
   Notes pursuant to Section 2 of the Purchase Agreement.

                       13.2  At such time as the pledge and security interest
   hereunder  shall  terminate, the Agent shall, if requested by the Pledgor,
   execute  such UCC termination statements or other documents as Pledgor may
   reasonably  request,  and  assign  and  deliver to the Pledgor, or to such
   person or persons as the Pledgor shall designate, against receipt, such of
   the  Collateral  (if any) as shall not have been sold or otherwise applied
   by  the  Agent  pursuant  to  the  terms hereof, together with appropriate
   i n s t r uments  of  reassignment  and  release  and  share  certificates
   representing  the Collateral and any stock power or instrument of transfer
   executed in blank, as the case may be, then remaining in the possession or
   under  the  control  of the Agent.  Any such reassignment shall be without
   recourse  upon  or warranty by the Agent (other than as to such Collateral
   being  free  of  any  lien or encumbrance created by the Agent) and at the
   expense of the Pledgor.

                 14.  Notices.  Notices and other communications provided for
   herein shall be in writing and shall be delivered by hand or shall be sent
   by  telecopy  (and  if  sent by telecopy, shall be confirmed by registered
   mail,  return  receipt requested, or by overnight mail or courier, postage
   and delivery charges prepaid), to the following addresses:

   Purchasers,  and  the execution and delivery, of the Notes pursuant to the
   Purchase  Agreement, and shall continue in full force and effect until the
   payment  in  full  of  the  Obligations  or the, conversion, redemption or

   agreements  by  or  on  behalf  of the parties which are contained in this
   Pledge Agreement shall bind and inure to the benefit of the successors and
   assigns of all other parties.

               17.  Reimbursement of Agent.  The Pledgor agrees to pay to the
   Agent  an  amount equal to the amount of all costs and expenses, including
   reasonable  legal  fees  and disbursements, resulting from any Collateral,
   this  Pledge Agreement (including the preparation of this Pledge Agreement
   and  all  related  documents  whether or not the transactions contemplated
   hereby  are consummated) or the administration and enforcement or exercise
   of  any right or remedy granted to the Agent hereunder or thereunder.  The
   foregoing  indemnity  agreement  includes any reasonable costs incurred by
   the  Agent  in  connection  with  any  action  or  proceeding which may be
   instituted  in  respect  of  the  foregoing  by the Agent, or by any other
   person  either  against the Agent or in connection with which any officer,
   agent  or  employee  of  the  Agent  is  called  as a witness or deponent,
   including,  but  not  limited to, the reasonable fees and disbursements of

   to  do hereunder or any representation or warranty of the Pledgor shall be
   breached,  the  Agent  may  (but shall not be obligated to) do the same or
   cause  it to be done or remedy any such breach and there shall be added to
   the  obligations  of  the  Pledgor  secured  hereby,  the  cost or expense
   incurred by the Agent in so doing, and any and all amounts expended by the
   Agent  in  taking  such  action  shall  be repayable to it upon its demand
   therefor  and  shall bear interest at 15% per annum from the date advanced
   to the date of repayment.

   The  Pledgor  s obligations contained in this Section 17 shall survive the
   expiration or earlier termination of this Pledge Agreement.

             18.  Indemnification by Pledgor.  The Pledgor hereby indemnities
   and  holds  harmless  the  Agent and the Purchasers (to the fullest extent
   permitted  by  applicable law) from and against, and agrees that the Agent
   and  the  Purchasers shall have no liability or obligation arising out of,
   any and all claims, demands, losses, judgments, liabilities, penalties and
   expenses  (including,  without limitation,  reasonable attorneys  fees and
   disbursements) of any nature whatsoever, arising out of or related to this
   Pledge  Agreement  or  the  Collateral,  including  with  respect  to  the
   Collateral  any  such  claims  (i)  asserted  before  the taking of actual
   possession  or control of the relevant Collateral by the Agent pursuant to
   this  Pledge Agreement, (ii) arising out of any act of, or omission to act
   on  the  part  of,  any party prior to such taking of actual possession or
   control  by  the  Agent  (whether  asserted before or after such taking of
   possession or control), or (iii) arising out of any act on the part of the
   Pledgor, its agents or affiliates before or after the commencement of such
   actual possession or control by the Agent.

   All  indemnities contained in this Section 18 shall survive the expiration
   or earlier termination of this Pledge Agreement.

             19.  Governing Law.  This Pledge Agreement shall be governed by,
   and construed in accordance with, the laws of the State of New York (other
   than  any  conflict  of laws rule which might result in the application of
   the laws of any other jurisdiction).

                    20.  Failure to Act Not a Waiver.  Neither any failure to
   exercise, nor any delay on the part of the Agent in exercising, any right,
   power  or privilege hereunder shall operate as a waiver thereof, nor shall
   a  single  or  partial  exercise  thereof  preclude  any  other or further
   exercise of any right, power or privilege.

              21.  Modification.  No modification, amendment or waiver of any
   provision of this Pledge Agreement, and no consent to any departure by the
   Pledgor herefrom, shall in any event be effective unless the same shall be
   in  writing and signed by the Agent, and then such waiver or consent shall
   be  effective  only in the specific instance and for the purpose for which
   given.    No  notice to or demand on the Pledgor in any case shall entitle
   the  Pledgor to any other or further notice or demand in the same, similar
   or other circumstances.

                22.  Severability.  In case any one or more of the provisions
   contained   in  this  Pledge  Agreement  should  be  invalid,  illegal  or
   unenforceable in any respect, the validity, legality and enforceability of
   the remaining provisions contained herein shall not in any way be affected
   or  impaired  thereby.    To  the  extent permitted by applicable law, the
   parties  hereby  waive any provision of law which may render any provision
   hereof invalid, illegal or unenforceable in any respect.

             23.  Counterparts.  This Pledge Agreement may be executed by the
   parties  hereto  in separate counterparts, each of .which when so executed
   and  delivered  shall  be  an  original,  but  all such counterparts shall
   together  constitute  one and the same instrument, and all signatures need
   not appear on any one counterpart.

   Agreement  are  for  convenience  of  reference only and shall not define,

                    25.  CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  THE
   PLEDGOR  HEREBY CONSENTS TO THE JURISDICTION OF ANY STATE OR FEDERAL COURT
   LOCATED  WITHIN  THE COUNTY OF NEW YORK, STATE OF NEW YORK AND IRREVOCABLY
   AGREES  THAT,  SUBJECT  TO  THE  ELECTION  OF  THE  AGENT,  ALL ACTIONS OR
   PROCEEDINGS RELATING TO THIS PLEDGE AGREEMENT OR THE SUBJECT MATTER HEREOF
   MAY  BE  LITIGATED  IN SUCH COURTS.  THE PLEDGOR ACCEPTS FOR ITSELF AND IN
   CONNECTION   WITH  ITS  PROPERTIES,  GENERALLY  AND  UNCONDITIONALLY,  THE
   EXCLUSIVE  JURISDICTION  OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF
   FORUM  NON  CONVENIENS, AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT
   RENDERED  THEREBY IN CONNECTION WITH THIS PLEDGE AGREEMENT AND THE SUBJECT
   MATTER  HEREOF.    THE  PLEDGOR  HEREBY  AGREES  THAT  SERVICE  UPON IT BY
   REGISTERED  MAIL,  RETURN  RECEIPT  REQUESTED, SHALL CONSTITUTE SUFFICIENT
   NOTICE  AND  SERVICE  OF PROCESS IN ANY SUCH PROCEEDING IN ANY SUCH COURT.
   NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER
   PERMITTED  BY  LAW  OR  SHALL  LIMIT  THE  RIGHT  OF  THE  AGENT  TO BRING
   PROCEEDINGS  OR  OBTAIN  OR  ENFORCE  JUDGMENTS AGAINST THE PLEDGOR IN THE
   COURTS OF ANY OTHER JURISDICTION.

                 26.  WAIVER OF JURY TRIAL.  THE PLEDGOR AND THE AGENT HEREBY
   WAIVE  THEIR  RESPECTIVE  RIGHTS  TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF
   ACTION  BASED  UPON OR ARISING OUT OF THIS PLEDGE AGREEMENT OR THE SUBJECT
   MATTER  HEREOF OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER

   ENCOMPASSING  OF  ANY  AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND
   THAT  RELATE  TO  THE  SUBJECT  MATTER OF THIS PLEDGE AGREEMENT, INCLUDING
   WITHOUT  LIMITATION,  CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS,
   AND  ALL OTHER COMMON LAW AND STATUTORY CLAIMS.  THE PLEDGOR AND THE AGENT
   FURTHER  WARRANT AND REPRESENT THAT EACH HAS REVIEWED THIS WAIVER WITH ITS
   LEGAL  COUNSEL,  AND  THAT  EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY
   TRIAL  RIGHTS  FOLLOWING  CONSULTATION WITH LEGAL COUNSEL.  THIS WAIVER IS
   IRREVOCABLE,  MEANING  THAT  IT  MAY  NOT  BE MODIFIED EITHER ORALLY OR IN
   WRITING,  AND  THIS  WAIVER  SHALL  APPLY  TO  ANY  SUBSEQUENT AMENDMENTS,
   RENEWALS,  SUPPLEMENTS OR MODIFICATIONS TO (OR ASSIGNMENTS OF) THIS PLEDGE
   AGREEMENT.    IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A
