such Year.

         4. Indemnity. UCAR agrees to indemnify and hold Graph-Tech and its
subsidiary harmless from and against any claims of liability for federal income

                  calendar quarter during the term hereof, without any setoff,
                  counterclaim or deduction for any reason whatsoever. The rent

         4.2      In its occupation and use of the Premises, Tenant shall comply
                  fully with all applicable local, State and Federal laws,
                  ordinances, orders, directives, rules and regulations. Tenant
                  shall not by reason of its use of the Premises at any time
                  throughout the term of this Agreement violate or cause to be
                  violated any laws, ordinances, orders, directives or rules or
                  regulations of any local, State or Federal authorities having

                  amount of waste, which may be accumulated at the initial point
                  of generation, then Tenant shall comply with such
                  requirements.

         4.4      In its occupation and use of the Premises, Tenant shall comply
                  at a minimum with any health, safety or operating regulations

                  be made at the Tenant's sole cost and expense and Tenant shall
                  be entitled to any and all salvage. Landlord shall cooperate
                  with Tenant in any governmental applications or otherwise in

                                    provided, to the Premises those services in
                                    the respective quantities and subject to the
                                    specifications and limitations as set forth
                                    in Exhibit B attached hereto (hereinafter
                                    individually and collectively called the
                                    "Services"). Pursuant to Article 3.2, Tenant
                                    shall reimburse Landlord for the
                                    fully-absorbed costs of providing the
                                    Services based upon the charges as set forth
                                    in Exhibit B.

                           (b)      Landlord will provide, or cause to be
                                    provided, the Services solely in conjunction
                                    with the demise of the Premises and as
                                    necessary in order to permit Tenant to enjoy
                                    the full use and occupation thereof. Tenant
                                    shall not make available or resell any
                                    Services delivered hereunder to any other
                                    party. The Services provided by Landlord, or
                                    caused to be provided, shall not be deemed
                                    evidence that Landlord is operating or
                                    holding itself out as a public utility or
                                    that it will make available the Services to
                                    any other party.

                           (c)      Landlord shall not be liable to Tenant for
                                    any claims, damages, loss or liability due
                                    to (i) Landlord's inability or failure to
                                    furnish, or cause to be furnished, any of
                                    the Services pursuant to the provisions of
                                    Exhibit B on account of any force majeure
                                    occurrence as described in Article 21.1,
                                    (ii) any failure of Landlord's utility
                                    suppliers to provide adequate and reliable
                                    service which affects Landlord's ability to
                                    provide, or cause to be provided, any of the
                                    Services, or (iii) any failure, interruption
                                    or curtailment of any of the Services due to
                                    equipment, labor or other problems which do
                                    not arise out of the gross negligence or
                                    willful misconduct of Landlord, its
                                    employees, agents or contractors. In no
                                    event shall Landlord be liable to Tenant for
                                    any special, incidental or consequential
                                    damages due to any failure, interruption or
                                    curtailment of any of the Services.

                           (d)      In the event of any force majeure occurrence
                                    as to any of the Services or any other
                                    failure, interruption or curtailment

                                    of such Services which prevents Landlord
                                    from having adequate capacity to supply its
                                    own needs and those of Tenant, Landlord
                                    shall have the right to allocate the
                                    available quantity of any such Service on a
                                    fair and reasonable basis according to the
                                    respective prior usage demands of Landlord,
                                    Tenant and other tenants of the Plant Site.

         7.2      In the event that Landlord cannot lawfully provide, or cause
                  to be provided, any of the Services without qualifying as a
                  public utility or without violation of applicable utility
                  tariffs, then (i) Landlord shall have no further liability or
                  obligation to provide, or cause to be provided, any of such
                  Services, (ii) Landlord's failure to provide, or cause to be
                  provided, such Services for any of the reasons specified in
                  this Section shall not be deemed a partial or constructive
                  eviction, and (iii) Landlord and Tenant shall cooperate in
                  good faith in order to permit Tenant's receipt of any of such
                  Services directly from a third-party utility supplier;
                  provided, however, that all costs and expenses arising out of
                  such changeover shall be shared equally by Tenant and
                  Landlord, subject to Landlord's prior written approval of any
                  such proposed work. In the event that Landlord ceases to
                  provide, or cause to be provided, any of the Services pursuant
                  to the immediately preceding sentence, then the applicable
                  additional rent payable pursuant to Section 3.2 shall be
                  eliminated.

         7.3      Upon written notice to Tenant, Landlord shall have no further
                  obligation to provide the Services and Tenant shall operate
                  the Facilities for the benefit of the Plant Site and any
                  tenants of Landlord, as may exist from time to time, subject
                  to their equitable contribution of any costs related to
                  Services furnished for their benefit. Upon assuming
                  responsibility for operation of the Facilities, Tenant shall
                  have no further payment obligations under Section 3.2 and
                  Tenant shall have and enjoy all protections granted to
                  Landlord under Sections 7.1 and 7.2 as though Tenant were
                  Landlord for such purposes.

         7.4      Tenant shall reimburse Landlord, as they become due, for (i)
                  Tenant's proportionate share of ad valorem taxes and
                  assessments levied, assessed or imposed upon the Premises and
                  apportioned to the term hereof; and (ii) any taxes, excises or
                  other governmental impositions payable by Landlord (other than
                  those as measured by net income) which arise due to any
                  payments of rent, additional rent or other amounts made
                  hereunder.

         7.5      Tenant's proportionate share of ad valorem taxes and
                  assessments applicable to the Premises which shall be payable
                  pursuant to Section 7.4 shall be determined based upon the
                  ratio which the valuation of the Premises for tax purposes
                  represents to the total valuation of the Plant Site for tax
                  purposes. Representatives of Landlord and Tenant shall meet
                  annually to review this matter and determine a suitable ratio.

         7.6      Landlord shall pay when due all ad valorem taxes and
                  assessments levied, assessed or imposed upon the Premises
                  during the term hereof. If at any

                                       8
<PAGE>   9

                  time Landlord defaults in the payment of any ad valorem taxes
                  and assessments due upon the Premises, including any taxes and
                  assessments due upon adjoining property comprising part of the
                  same tax parcel, then upon ten (10) day's prior written notice
                  to Landlord, Tenant shall have the right to pay the same and
                  deduct such payment from its monthly rent.

         7.7      Tenant shall pay and discharge when due all personal property
                  taxes applicable to its property located upon the Premises and
                  all income, business, Social Security and other taxes, levies,
                  impositions and contributions required by any Federal, State
                  or local authority applicable to Tenant's business conducted
                  upon the Premises. Tenant shall indemnify and hold harmless
                  Landlord from any liability for such taxes, levies,
                  impositions and contributions.

         7.8      If at any time during the term of this Agreement, (i) a tax,
                  excise or other imposition is levied, assessed or imposed upon
                  or measured by the rent, additional rent or other charges
                  payable by Tenant hereunder, other than a tax, excise or
                  imposition as measured by net income, or (ii) a capital levy
                  or other imposition is made based on the value of the Premises
                  or Tenant's property within the Premises, or (iii) some other
                  form of assessment based in whole or in part on some other
                  valuation of the property then comprising the Premises is
                  imposed, then, and in any such event, Tenant shall reimburse
                  Landlord for any such tax, excise, levy or imposition paid by
                  it.

         7.9      All payments required to be made by Tenant to Landlord under
                  this Section 7 shall be payable as additional rent within ten
                  (10) days after written demand therefor and shall be payable
                  even though the term hereof (including and extensions) has
                  expired, provided that they are applicable to any tax period
                  falling within said term (including any extensions).

ARTICLE 8 - TERMINATION OF LEASE

         8.1      At the expiration or earlier termination of the term, Tenant
                  shall promptly vacate and yield up the Premises, broom clean
                  and in the same condition or order and repair in which they
                  are required to be kept throughout the term hereof, reasonable
                  wear and tear excepted.

         8.2      Upon the termination of this Agreement, Tenant shall have the
                  right to remove all of Tenant's property which has been
                  affixed, attached or otherwise made part of the Premises or
                  any fixtures or equipment belonging to Tenant which it is
                  permitted to remove pursuant to Section 6.2; provided,
                  however, that in performing such work Tenant shall not impair
                  the structural integrity or the utility systems of the
                  buildings comprising the Plant Site and that in each instance
                  Tenant repairs any damages to the Premises due to the
                  installation or removal of such property. Any fixtures,
                  equipment or other property of Tenant remaining upon the
                  Premises at the expiration or termination of this Agreement
                  shall be deemed abandoned and may be removed or otherwise
                  disposed of by Landlord without any notice of liability or
                  obligation to Tenant, but

                  upon the expiration or other termination of this Agreement,

                  any repairs to the Premises as required in Article 8, (ii) to
                  remove and dispose of properly any garbage, waste or other
                  debris, (iii) to remove and dispose of any other property
                  abandoned upon the Premises, and (iv) to eliminate any

                  does not promptly perform any such work as requested by
                  Landlord, Tenant shall be liable to reimburse Landlord the
                  cost of so doing.

                  delayed, cause the installation, at Tenant's cost and expense,
                  of such signs as it may require to identify Tenant's occupancy
                  of the Premises. Tenant shall be responsible to repair any
                  damage to the Premises caused by such installation, and Tenant
                  shall remove such signs at the expiration or other termination

                  removal. Tenant shall fully comply with all requirements of
                  law pertaining to installation and use of such signs. Tenant
                  may, in compliance with law, install directional signs in the
                  parking areas, or at or near the street, directing traffic

                  Premises.

         9.2      Tenant shall be solely liable for the security of any of its
                  property located upon the Premises. In no event shall Landlord
                  be liable for any loss, theft, or destruction of any property
                  located upon the Premises of any bodily injury, death,
                  sickness or disease of any employees, agents, contractors or

                  without limitation, the leakage or escape of any steam,
                  electricity, gas, water, sewage, compressed air or other
                  utility service, the existence of any ice or show upon any
                  sidewalks, driveways or parking areas adjoining the Premises,
                  the state of repair of the Plant Site or the Premises or any
                  latent defect therein; and Tenant shall indemnify and hold
                  harmless Landlord from all claims, damages, losses and
                  liability on account of such matters.

         10.1     No more than once per year during normal business hours and at
                  any time in the event of emergency, Tenant shall upon
                  reasonable notice permit Landlord and the agents and
                  contractors of Landlord to enter the Premises for the purpose
                  (i) inspecting the same, (ii) during the final year of the
                  term showing the Premises to any prospective tenants or

         10.2     Landlord reserves the right at any time to enter upon the
                  Premises and to make any necessary repairs thereto, including

                  any nuisances or any dangerous, harmful or unhealthful
                  condition existing thereon. The reservation of such rights
                  shall not be deemed to be an acknowledgement of or imply any
                  duty or obligation on the part of Landlord to perform any such
                  actions, except where the obligation to do so is otherwise
                  specifically set forth herein. Tenant shall be solely liable
                  for the condition and upkeep of the Premises.

                  Premises or any portion thereof, or license or enter into
                  concession agreements covering departments therein and may
                  assign this Lease in writing, provided that:

                           (a) No such assignment nor the acceptance of rent by
                           the Landlord from such assignee shall relieve,
                           release or in any manner affect the liability of the
                           Tenant;

                           (b) Any such assignee shall, in writing, assume and
                           agree to keep, observe and perform all of the
                           agreements, conditions, covenants and terms of this
                           Lease on the part of the Tenant to be kept, observed
                           and performed and shall be, and become jointly and
                           severally liable with the Tenant for the
                           non-performance thereof accruing from said date;

                           (c) No further or additional assignment of the Lease
                           shall be made except upon compliance with and subject
                           to the provisions of this Article; and

                           (d) Any subletting shall be subject to all the terms,
                           conditions and covenants of this Lease.

         11.2     Tenant shall have the right to mortgage Tenant's interest in
                  this Lease, or to assign, pledge or hypothecate the same as
                  security for any leasehold mortgage. No leasehold mortgage
                  shall be binding upon Landlord in the enforcement of its
                  rights and remedies herein and by law provided, unless and
                  until an executed counterpart thereof, together with the
                  address of the leasehold mortgagee thereunder, shall have been
                  delivered to Landlord.

                           default under the provisions of this Lease, Landlord
                           will also serve a copy of such notice upon the
                           leasehold mortgagee and no such notice to Tenant
                           shall be effective unless a copy of such notice is so
                           served upon the leasehold mortgagee; a copy of such
                           notice shall be deemed served upon the leasehold
                           mortgagee if sent by Landlord, by registered or
                           certified mail, to the address of the leasehold
                           mortgagee as shown on the executed counterpart of the
                           leasehold mortgage delivered to Landlord pursuant to
                           Section 11.2;

                           (b) The leasehold mortgagee will have the same period
                           after the serving of any notice as aforesaid upon it
                           for curing a default in the payment of fixed rent or
                           additional rent or causing the same to be cured as is
                           given Tenant after notice to Tenant;

                           (c) In case Tenant shall default under any of the
                           provisions of this Lease, the leasehold mortgagee
                           shall have the right to cure such default whether the
                           same consists of the failure to pay fixed rent or
                           additional rent or the failure to perform any other
                           act which Tenant is hereby required to do or perform
                           and Landlord shall accept such performance on the
                           part of the leasehold mortgagee as though the same
                           had been done or performed by Tenant;

                           (d) In case Tenant shall default under any of the
                           provisions of this Lease, other than in the payment
                           of the fixed rent or additional rent, Landlord will
                           take no action to effect a termination of this Lease
                           without first giving notice to the leasehold
                           mortgagee; and

                                    (i) The leasehold mortgagee shall have a
                                    period of twenty (20) days within which
                                    either to obtain possession of the Premises
                                    or to institute foreclosure proceedings or
                                    obtain the appointment of a receiver, or
                                    otherwise acquire Tenant's interest under
                                    this Lease, and an additional period of
                                    thirty (30) days thereafter within which to
                                    cure such default (except that in the case
                                    of a default which cannot be cured with due
                                    diligence within such period of thirty (30)
                                    days whether due to unavoidable delays or
                                    otherwise, such period shall be extended for
                                    such time as may be necessary to cure the
                                    default except as prevented by unavoidable
                                    delays); or

                                    (ii) In case of a default which is not
                                    susceptible of being cured by the leasehold
                                    mortgagee as provided in subdivision (i)
                                    above, the Landlord will further extend the
                                    periods referred to in such subdivision (i)
                                    to permit the leasehold mortgagee to

                                    diligently such default provided, however,
                                    that the leasehold mortgagee shall not be
                                    required to continue such possession or
                                    continue such foreclosure proceedings or
                                    receivership if the default shall be cured;
                                    and provided further that during any such
                                    time there shall be no default in the
                                    payment of the fixed rent or additional
                                    rent;

                           (e) Any leasehold mortgagee may become the legal
                           owner and holder of this Lease by foreclosure of its
                           leasehold mortgage or as a result of the assignment
                           of this Lease in lieu of foreclosure, and in such
                           event, the leasehold mortgagee shall assume due
                           performance of the obligations on Tenant's part to be
                           performed under this Lease;

                           (f) If, by reason of any default by Tenant, this
                           Lease shall be terminated by Landlord prior to the
                           expiration of the term of this Lease, Landlord will
                           enter into a new lease of the Premises with the

                  the term hereunder) as such leasehold mortgagee may reasonably
                  require, so long as such modifications or amendments shall not

                  obligations hereunder, and provided that such modifications or
                  amendments shall be approved by the holder of the

                  rent by the Landlord from any such assignee, mortgagee or
                  subtenant, remain liable for the payment of rent hereunder and

                  Premises. Tenant shall release and indemnify and hold harmless
                  Landlord from any claims, damages, loss or liability arising
                  as a result of damage or destruction to such property or

                  loss or damage by fire or any other cause within the scope of
                  said fire and extended coverage insurance policies.

                  ($1,000,000) per occurrence for one (1) person, five million
                  dollars ($5,000,000) per occurrence for two (2) or more

                  12.1

         12.4     At its sole cost and expense, Tenant shall maintain and keep

                  coverage required under Sections 12.2, 12.3, and 12.4, and
                  each such policy of insurance shall name Landlord as an
                  additional insured and provide that it shall not be amended,
                  modified or cancelled, except upon thirty (30) days' prior
                  written notice to Landlord.

         12.6     In no event shall Landlord be liable to Tenant for any
                  special, indirect, incidental or consequential damages on

                  claims, damages or losses of Tenant arising out of its
                  possession, occupation or use of the Premises.

                  by its insurer against Tenant, except to the extent of any
                  deductible amount under such coverage.

ARTICLE 13 - DEFAULT

                  (b)      dissolution or liquidation of Tenant, without the
                           transfer to and assumption by a financially
                           responsible third-party of this Agreement;

                  (c)      appointment of a permanent or temporary receiver or a
                           permanent or temporary trustee of all or

                  (d)      taking possession of the property of Tenant by a
                           governmental officer or agency pursuant to statutory
                           authority for dissolution, rehabilitation,

                  (e)      making by Tenant of an assignment for the benefit of
                           creditors.

                  If any event mentioned in this subdivisions (a-e) shall occur,
                  Landlord may thereupon or at any time thereafter elect to
                  cancel this Agreement upon ten (10) days' prior written notice
                  to Tenant and this Agreement

                                       15
<PAGE>   16

                  shall terminate on the day in such notice specified with the
                  same force and effect as if that date were the date herein
                  fixed for the expiration of the terms of this Agreement.

                  (f)      Default in the payment of the rent or additional rent
                           herein reserved or any party thereof for a period of
                           fifteen (15) days after receipt of written notice
                           concerning such default.

                  (g)      Default in the performance of any other covenant or
                           condition of this Agreement on the part of Tenant to
                           be performed for a period of thirty (30) days after
                           written notice from Landlord specifying the nature of
                           such default. For purposes of this subdivision, no
                           default on the part of Tenant in performance of work
                           required to be performed on acts to be done shall be
                           deemed to exist if after receipt of the aforesaid
                           notice Tenant diligently takes action to rectify the
                           same and prosecutes such action to completion with
                           reasonable diligence, subject, however, to
                           unavoidable delays.

         13.3     In case of any such default under Article 13.1(f) or (g) and
                  at any time thereafter following the expiration of the
                  respective grace periods above-mentioned, Landlord may serve a
                  notice upon the Tenant electing to terminate this Agreement
                  upon a specified date not less than ten (10) days after the
                  date of serving such notice and this Agreement shall expire on
                  the date so specified as if that date had been originally
                  fixed as the expiration date of the term herein granted and
                  all rent and additional rent applicable to the balance of the
                  term hereof or any then existing extension term shall
                  thereupon become due and payable. However, a default under
                  Section 13.1(f) or (g) shall be deemed waived if such default
                  is cured before the date specified for termination in the
                  notice of termination served on Tenant pursuant to this
                  Section.

         13.4     In the event this Agreement shall be terminated pursuant to
                  this Article or by summary proceedings or otherwise, Landlord
                  shall mitigate its damages and Landlord may, in its own name
                  and in its own behalf, relet the whole or any portion of the
                  Premises, for any period equal to or greater of less than the
                  remainder of the then current term for any sum which it may
                  deem reasonable, to any Tenant which it may suitable and
                  satisfactory, and for any use and purpose which it may deem
                  appropriate, and in connection with any such lease Landlord
                  may make such changes in the character of the improvements on
                  the Premises as Landlord may determine to be appropriate or
                  helpful in effecting such lease. However, in no event shall
                  Landlord be under any obligation to pay or credit Tenant with
                  any surplus of any sums received by Landlord on a reletting of
                  the Premises in excess of the rent reserved in this Agreement.

         13.5     All remedies specified in this Section shall be non-exclusive
                  and Landlord's reliance upon such remedies shall not preclude
                  it from availing itself of any other rights or remedies which
                  it may have at law or in equity.

ARTICLE 14 - FIRE AND CASUALTY

         14.1     In the event of any damage to or destruction of the Premises
                  by fire or other occurrence so that twenty percent (20%) or
                  more of the building floor area comprising the Plant or the
                  Premises becomes untenable or unfit for occupancy, then within
                  thirty (30) days after the date of such occurrence, either
                  Landlord or Tenant shall have the right to elect by written
                  notice to the other to cancel this Agreement as of the date of
                  such damage or destruction, in which event the rent and
                  additional rent shall be apportioned to such date. If neither
                  party duly elects to cancel this Agreement pursuant to the
                  immediately preceding sentence, then Landlord shall repair and
                  restore the Premises to substantially their same condition
                  prior to such occurrence using reasonable speed and dispatch
                  and the rent and additional rent shall be equitably abated as
                  set forth in the following Section from the date of such
                  occurrence until the date when repairs are completed.

         14.2     In the event of any fire or other occurrence which damages or
                  destroys less than twenty (20%) of the building floor area
                  comprising the Premises, Landlord shall repair and restore the
                  Premises with reasonable speed and dispatch, and the rent and
                  additional rent shall be equitably abated in the same
                  proportion that the area of the Premises which shall be
                  untenable of unfit for occupancy by Tenant in the conduct of
                  its business represents to the total area of the Premises,
                  from the date of such destruction until the completion of such
                  repairs.

         14.3     In the event that a fire or other occurrence as provided in
                  Section 14.2 happens during the final 180 days of the term
                  hereof, or any extension periods, Landlord shall not be
                  obligated to repair and restore the Premises, and this
                  Agreement shall remain in full force and effect, subject to an
                  equitable abatement of rent, fees and additional rent, until
                  the expiration of the term hereof.

         14.4     In no event shall Landlord have any liability or obligation to
                  Tenant with respect to the repair or restoration of any
                  property of Tenant located upon the Premises due to any fire
                  or other occurrence. In the event this Agreement is cancelled
                  pursuant to Section 14.1, then Tenant shall remain obligated
                  promptly to remove or eliminate any nuisance or dangerous,
                  harmful or unhealthful condition then existing on or about the
                  Premises due to its use thereof.

ARTICLE 15 - CONDEMNATION

         15.1     If due to any condemnation or taking by any public or
                  quasi-public authority or other party having the right of
                  eminent domain, (i) twenty percent (20%) or more of the
                  building floor area comprising the Premises is taken, or (ii)
                  access to the Premises is permanently denied, then and in any
                  of the aforesaid events' the term of this Agreement shall, at
                  the option of Tenant, cease and become null and void from the
                  date when the party

                                       17
<PAGE>   18

                  exercising the power of eminent domain actually takes or
                  interfered with the use of the Premises or denies access

                           inventory and personal property, whether or not the
                           same are permanently attached to the realty and
                           whether or not they can be easily removed without
                           substantial injury to the freehold, and for the value
                           of this Lease;

                           (ii) Any claim now or hereafter permitted by law for

                           part of the Premises.

         15.3     In the event of any partial taking which does not cause a
                  termination of this Agreement pursuant to Section 15.1, then
                  the rent and additional rent shall abate in an amount mutually
                  acceptable to Landlord and Tenant based on the effect the
                  taking shall have on Tenant's operation and the relationship
                  that the area of the Premises taken bears to the area of the
                  Premises prior to such condemnation.

         15.4     After any condemnation or other taking as specified in Section
                  15.1 and 15.2, Landlord shall, at its sole cost and expense,

                           and effect, if such be the case, or if there have
                           been any modifications, that the

                           there are then existing any set-offs or defenses
                           against the enforcement of any of the agreements,
                           terms, covenants or conditions of this Lease and any
                           modifications of this Lease upon the part of Tenant
                           to be performed or complied with, and if so,

                  Landlord's interest in the Premises or in the event of any
                  proceedings brought for the foreclosure of or in the event of
                  exercise of the power of sale under any mortgage made by
                  Landlord covering the Premises, upon written notice, to the
                  purchaser and recognize such purchaser as Landlord under this
                  Lease, provided, however, that such purchaser or other
                  successor in interest to the Landlord recognize Tenant and
                  assume Landlord's obligations hereunder, including without
                  limitation obligations for prior and future defaults or
                  offsets provided for herein. Any such purchaser or successor
                  shall also furnish proper legal evidence of its rights to the
                  Premises and this Lease, and shall furnish its address for
                  notices. Tenant shall not be obligated to change the place it
                  sends rents and other charges hereunder until Tenant receives
                  all such documentation and information provided for in this
                  paragraph.

         20.4     Landlord shall, within ten (10) days after requested to do so
                  by the Tenant herein, deliver an estoppel certificate,
                  certified by written instrument duly executed and acknowledged
                  containing information regarding this Lease substantially as
                  set forth in Section 20.2. Such certificate shall run in favor
                  of any prospective mortgage holder of Tenant's interests
                  herein or any prospective assignee or subtenant of Tenant.

         20.5     Upon the request of a prospective Institutional First
                  Mortgagee, Tenant agrees to give due consideration to any
                  reasonable modifications or amendments of this Lease (except
                  with respect to the provisions for payment of fixed rent and
                  additional rent and the term hereunder) as such Institutional
                  First Mortgagee may reasonably request so long as such
                  modifications or amendments shall not increase Tenant's
                  obligations, decrease Tenant's rights or decrease Landlord's
                  obligations hereunder. Unless acceptable to Tenant, Tenant
                  shall have no obligation to accede to such requests.

                  to or devolve upon another, or in the event that the rent
                  accrued or to accrue hereunder shall be assigned, or in the
                  event that one other than Landlord shall become entitled to
                  collect the rent accrued or to accrue hereunder, then and in
                  any such event, notice of the fact shall be given to Tenant by
                  Landlord in writing, duly executed and acknowledged by
                  Landlord and, until such notice and proof shall be given to
                  Tenant, Tenant may continue to pay the rent accrued or to
                  accrue hereunder to the one to whom, and in the manner in
                  which, the last preceding installment of rent hereunder was
                  paid and each such installment shall, to the extent thereof,
                  fully exonerate and discharge Tenant. In the event that Tenant
                  shall pay rent or other charges hereunder to any person other
                  than Landlord in accord with any notice purporting to be
                  executed by or on behalf of Landlord, or by or on behalf of
                  the person who, under the terms of this Lease, shall give the
                  notice, and, which is believed in good faith by Tenant to be
                  genuine, such payment shall constitute payment and discharge
                  of the obligation of Tenant thus paid. In the event that
                  Tenant shall be advised of any dispute as to the person to
                  whom the rent under this Lease shall be payable, or shall
                  receive notice of any claim to the payment of rent or other
                  charges hereunder due or to accrue hereunder from a person
                  other than Landlord, Tenant shall promptly advise Landlord in
                  writing of the existence and nature of such claim and, unless
                  Landlord shall, within twenty (20) days of such advice by
                  Tenant, either advise the Tenant to pay the rent in accord
                  with such claim, or shall supply Tenant with a duly executed
                  release of such claim by the claimant or a direction from such
                  claimant to pay the rent to Landlord, Tenant shall be entitled
                  to pay any installment of rent or other charges hereunder so
                  claimed then due or thereafter to accrue

                  under this Lease, into a bank or trust company in the County
                  in which the Premises are located for deposit to the account
                  of Landlord and such claimant, and the making of such payment
                  to such bank or trust company, shall discharge Tenant of any
                  further obligation for the payment of the rent or other
                  charges hereunder so paid. Tenant shall be under no obligation
                  to recognize any agent for the collection of rent accrued or
                  to accrue hereunder or otherwise authorized to act with
                  respect to the Premises until written notice of the
                  appointment and the extent of the authority of such agent
                  shall be explicitly given by the one appointing such agent.

ARTICLE 29 - ENTIRE AGREEMENT

         29.1     This Agreement contains all the promises, agreements,
                  conditions and understanding between Landlord and Tenant with
                  respect to the leasing of the Premises, and there are no
                  promises, agreements, conditions or understandings, either
                  written or oral, between them other than as set forth herein.
                  No amendment, modification or addition to this Agreement shall
                  be effective unless it is contained in a written agreement
                  executed by authorized representatives of both parties.

         29.2     The covenants, conditions and agreements contained in this
                  Agreement shall being and inure to the benefit of the parties
                  hereto and their respective successors and permitted assigns.

ARTICLE 30 - OPTION FOR ADDITIONAL SPACE

         30.1     Should the remainder of the Plant Site not included within the
                  Premises composed of approximately 204,000 feet ever be
                  vacated by its current tenant (Advanced Ceramics Corporation)
                  or any future tenant, Tenant shall have the first right and
                  option to lease that additional space on similar terms and
                  conditions as may be in effect under this Lease during that
                  then current term. Rent shall be determined based on a
                  breakdown of the tenant's then current rent divided by 207,000
                  square feet to arrive at a per square foot rental rate. Tenant
                  may then rent such additional space within the Plant Site at
                  that rate and this Lease shall be amended to include that
                  additional space. For example, should the current tenant
                  vacate the property on the fifth (5th) year of Tenant's first
                  term, the rent for the additional space should be calculated
                  as follows:

                           (a)      $213,210.00/207,000 sq. feet = $1.03 per
                                    square foot.

                  That rental rate shall be in effect until the termination of
                  Tenant's first term or in five (5) years as provided in this
                  example.

                           (b)      Should Tenant elect not to immediately lease
                                    the additional space within the Plant Site,
                                    Tenant shall retain a right of

                                       25
<PAGE>   26

                                    first refusal against any other Tenant
                                    Landlord may desire. Landlord shall notify
                                    the tenant within ten (10) days of receiving
                                    an offer for lease of the space. Tenant then
                                    may either exercise its right to lease all
                                    or any part of the Plant Site or inform the
                                    Landlord that it waives its right of first
                                    refusal, solely as to the space to be rented
                                    to the prospective tenant.

ARTICLE 31 - RIGHT OF FIRST REFUSAL ON SALE OF THE PROPERTY

         31.1     Without affecting or limiting any of the rights, privileges,
                  options or estates granted to Tenant under this Lease, it is
                  agreed that if the Landlord at any time during the term of
                  this Lease receives one or more bona fide offers from third
                  parties to purchase the Premises and/or all or any part of the
                  Plant Site and if any such offer is acceptable to Landlord,
                  then Landlord agrees to notify Tenant in writing, giving the
                  name and address of the offeror, and the price, terms and
                  conditions of such offer, and Tenant shall have thirty (30)
                  days from and after the receipt of such notice from Landlord
                  in which to elect to purchase the same property for the
                  consideration contained in the bona fide offer. If Tenant does
                  not elect to purchase said property and Landlord thereafter
                  sells the property, the purchaser shall take the property,
                  subject to and burdened with all the terms, provisions and
                  conditions of this Lease, including this Article and the
                  rights of Tenant under this Lease as against the new owner
                  shall not be lessened or diminished by reason of the change of
                  ownership. Tenant's failure at any time to exercise its option
                  under this Article shall not affect this Lease or the
                  continuance of Tenant's rights and options under this Article
                  or any other Article.

         31.2     In the event Tenant elects to purchase the same property as
                  provided in this Lease, then Landlord shall, within thirty
                  (30) days after receipt of such notice of election by Tenant,
                  deliver to Tenant a title insurance policy in the amount of
                  the consideration set forth in such offer, issued by a
                  responsible title guarantee company, showing a good and
                  marketable title in Landlord. If Landlord fails or refuses to
                  furnish the title policy, then Tenant may, at its election,
                  procure the same at Landlord's expense, and in the amount of
                  the purchase price, and deduct the cost thereof from the cash
                  consideration to be paid for the property. Tenant shall have
                  thirty (30) days after receipt of the title policy in which to
                  examine the title and notify the Landlord whether or not the
                  title is acceptable to Tenant. If Tenant is willing to accept
                  Landlord's title and consummate the purchase, then Landlord
                  shall, within ten (10) days after written notice thereof from
                  Tenant, convey the premises to Tenant by general warranty
                  deed, free and clear of all liens and encumbrances except
                  highway easements, private road easements and restrictions of
                  record which were of record as of the

                                       26
<PAGE>   27

                  date of Tenant's acceptance of the premises hereunder or
                  incorporated in an amendment to this Lease, if any, and
                  deliver such deed to Tenant upon tender of the consideration.

         31.3     Notwithstanding any other provisions of this Lease, the
                  provisions of this Article will not apply to any sale of the
                  Premises or any property of which the Premises are a part at
                  foreclosure, and shall not be binding upon any purchaser at
                  foreclosure, any mortgagee in possession, or any holder of a
                  deed in lieu of foreclosure or the successors or assigns of
                  any of the foregoing, or to any sale of the Premises by
                  Landlord in connection with sale and leaseback financing.

         31.4     If Tenant is not willing to accept Landlord's title, Tenant
                  shall make any objections thereto in writing to Landlord and
                  Landlord shall be allowed sixty (60) days to utilize its best
                  efforts to make such title acceptable to Tenant. If such title
                  is not rendered marketable within sixty (60) days from the
                  date of said written objections thereto, Tenant may, at its
                  election, take such action, including instigation of legal
                  process (in which the Landlord agrees to participate) to
                  remedy any such defect in title making such acceptable to
                  Tenant, and to deduct all costs thereof from the cash
                  consideration to be paid for the property. If the Tenant is
                  unable to correct such defects in title or elects not to
                  attempt such remedy, neither party shall be held liable for
                  damages to the other party and both parties shall be released
                  of all liabilities and obligations under this Article.

ARTICLE 32 - LANDLORD'S TITLE

                           (a) Landlord is the owner of a fee simple estate in
                           the Premises and the Plant Site and has the right and

                           that the Tenant shall ever determine that there are
                           any liens or encumbrances on the Premises or the
                           Easements prior in lien to this Lease other than (i)

                           hereof, and if Landlord shall fail to cause such
                           liens or encumbrances to be removed within thirty
                           (30) days after notice thereof from Tenant, Tenant
                           may, within thirty (30) days after said thirty (30)
                           day period, in addition to any rights it may have at
                           law or equity, cancel this Lease by notice to
                           Landlord (or waive any such liens or encumbrances) in

         37.1     If at any time hereafter a dispute shall arise between
                  Landlord and Tenant with respect to any amount of money to be
                  paid by either of them to the other under any of the
                  provisions of this Lease, the party against whom the
                  obligation shall be asserted shall have the right to make
                  payment "under protest" and if such party shall exercise such
                  right such payment shall not be deemed a voluntary payment but
                  there shall be deemed reserved to such party the right to
                  institute appropriate action or proceeding against the other
                  for recovery of the whole or such part of said sum as such
                  party shall claim it was not obligated to pay hereunder. If at
                  any time a dispute shall arise between Landlord and Tenant as
                  to any act to be done or work to be performed by either of
                  them or in or about the Premises under any of the provisions
                  of this Lease, the party against whom the obligation to do
                  such act or perform such work shall be asserted, may do such
                  act or perform such work and pay the cost thereof "under
                  protest" and if such party shall do so the performance of such
                  act or work and payment of such cost shall not be deemed a
                  voluntary performance of voluntary payment, but there shall be
                  deemed reserved to such party the right to institute
                  appropriate action or proceedings against the other for
                  recovery of the whole of such cost or such part thereof as
                  shall represent the cost of performing the act or work which
                  such party shall claim it was not obligated to perform
                  hereunder.

In no event shall Tenant be obligated to pay rent to more than one entity at any
one time.
