     b. LEASE TERM ADJUSTMENT. If, for any reason, other than delays caused by

<Page>

keys to the Leased Premises if a building permit has not been applied for and/or
is not required by the appropriate authority.

     c. COST OF LIVING ADJUSTMENT. The Base Monthly Rental specified in
paragraph 4A above shall be recalculated for each Lease Year as defined
hereinafter following the first Lease Year of this Lease Agreement. The
recalculated Base Monthly Rental shall be hereinafter referred to as the
"Adjusted Monthly Rental". The Adjusted Monthly Rental for each Lease Year after
the first Lease Year shall be the greater of: (i) the amount of the previous
year's Adjusted Monthly Rental, (or the Base Monthly Rental if calculating the
Adjusted Monthly Rental for the second Lease Year), or (ii) an amount calculated
by the rent adjustment formula set forth below. In applying the rent adjustment
formula, the following definitions shall apply:

          i. "Lease Year" shall mean a period of twelve (12) consecutive full
calendar months with the first Lease Year commencing on the date of the
commencement of the term of this Lease and each succeeding Lease Year commencing
upon the anniversary date of the first Lease Year; however, if this Lease does
not commence on the first day of a month, then, the first Lease Year and each
succeeding Lease Year shall commence on the first day of the first month
following each anniversary date of this Lease;

          ii. "Bureau" shall mean the Bureau of Labor Statistics of the United
States Department of Labor or any successor agency that shall issue the Price
Index referred to in this Lease Agreement.

          iii. "Price Index" shall mean the "Consumer Price Index-All Urban
Consumers-All Items (CPI-U) U.S. City Average (1982-84=100)" issued from time to
time by the Bureau. In the event the Price Index shall hereafter be converted to
a different standard reference base or otherwise revised, the determination of
the increase in the Price Index shall be made with the use of such conversion
factor, formula or table as may be published by Prentice-Hall, Inc. or failing
such publication, by another nationally recognized publisher of similar
statistical information. In the event the Price Index shall cease to be
published, then, for the purposes of this paragraph 4C there shall be
substituted for the Price Index such other index as the Landlord and the Tenant
shall agree upon, and if they are unable to agree within sixty (60) days after
the Price Index ceases to be published, such matter shall be determined by
arbitration in accordance with the Rules of the American Arbitration
Association.

public during the second calendar month preceding the commencement of this Lease
Agreement.

          v. "Revised Price Index" shall mean the Price Index released to the
public during the second calendar month preceding the Lease Year for which the
Base Annual Rental is to be adjusted;

          vi. "Basic Monthly Rental" shall mean the Basic Monthly Rental set

the Adjusted Monthly Rental is as follows:

               Adjusted Monthly = Revised Price Index X Base Monthly Rental
                       Rental     -----------------------------------------
                                          Base Price Index

Not withstanding the above formula, the Adjusted Monthly Rental shall not be
greater than 103% of the previous year's Adjusted Monthly Rental, or the Basic
Monthly Rental if such adjustment is for the Second Lease Year. The Adjusted
Monthly Rental as herein above provided shall continue to be payable monthly as
required in paragraph 4A above without necessity of any further notice by the
Landlord to the Tenant.

     d. TOTAL NET LEASE. The Tenant understands and agrees that this Lease
Agreement is a total net lease (a "net, net, net lease"), whereby the Tenant has
the obligation to reimburse the Landlord for a share of all costs and expenses
(taxes, assessments, other charges, insurance, trash removal, Common Area
operation and maintenance and like costs and expenses), incurred by the Landlord
as a result of the Landlord's ownership and operation of the Area.

5. SECURITY DEPOSIT. Landlord acknowledges receipt from the Tenant of the sum of

reasonable cost of repairs to the Leased Premises (ordinary wear and tear
excepted), for any rent delinquent under the terms hereof and/or for any sum
used in any manner to cure any default of Tenant under the terms of this Lease
Agreement. In the event deductions are so made, the Tenant shall, upon notice
from the Landlord, redeposit with the Landlord such amounts so expended so as to
maintain the deposit in the amount as herein provided for, and failure to so
redeposit shall be deemed a failure to pay rent under the terms hereof. Nothing
herein contained shall limit the liability of Tenant as to any damage to the
Leased Premises, and Tenant shall be responsible for the total amount of any
damage and/or loss occasioned by actions of Tenant. Landlord may deliver the
funds deposited hereunder by Tenant to any purchaser of Landlord's interest in
the Leased Premises in the event such interest shall be sold, and thereupon
Landlord shall be discharged from any further liability with respect to such
deposit.

6. USE OF PREMISES. Tenant shall use the Leased Premises for reasonable purposes
related to analytical and chemistry laboratories, biotech laboratories, clean
rooms, research & development, manufacturing, warehousing, office and

contents thereof, a waiver of any right of subrogation any such insurer of one
party may acquire against the other or as against the Landlord or Tenant by

of such costs which are directly attributable to the unreasonable actions of
Landlord or Landlord's tenants which share or have access to the area larger
than the leased premises. Tenant shall pay monthly, commencing with the first
month of the Lease Term, as additional rent due under the terms hereof, a sum
equal to Tenant's Prorata Share of the estimated costs for said twelve (12)
month period, divided by 12. Once each year the Landlord shall determine the
actual costs of the foregoing expenses for the prior year and if the actual
costs are greater than the estimated costs, the Tenant shall pay its Tenant's
Prorata Share of the difference between the estimated costs and the actual costs
to the Landlord with the next payment of Base Monthly Rent, or, if the actual
costs are less than the estimated costs, the Landlord shall forthwith refund the
amount of the Tenant's excess payment to the Tenant. Additionally, upon Lease
expiration or termination Landlord shall also determine Tenant's Prorata Share
of the annualized actual costs of the foregoing expenses for the number of days
the Lease is in effect during the calendar year in which the Lease expires or
terminates. If the annualized actual costs are greater than the estimated costs,
the Tenant shall pay its Tenant's Prorata Share of the difference between the
estimated costs and the annualized actual costs to the Landlord, or, if the
annualized actual costs are less than the estimated costs, the Landlord shall
forthwith refund the excess payment to the Tenant. For purposes of calculating
Tenant's share of expenses under this paragraph, annualized actual costs shall
be the sum of actual costs for the year at the time of reconciliation plus the
total estimated costs prorated for the number of days from the date the last
actual cost was paid to the end of the year. For all utility services used or
consumed on the Leased Premises in which the utility service is used solely on
the Leased Premises, the Tenant shall forthwith upon taking occupancy of the
Leased Premises make arrangements with the Excel Energy Company, U.S. West or
other appropriate utility company to pay the utilities used on the Leased
Premises and to have the same billed to the Tenant at the address designated by
the Tenant. Should there be a time where the Landlord remains responsible for
utilities supplied to the Leased Premises, the Landlord shall bill the Tenant
therefore and the Tenant shall promptly reimburse the Landlord therefore. In no
event shall Landlord be liable for any interruption or failure

                                  Page 4 of 19
<Page>

in the supply of any such utility to the Leased Premises.

         In the event the utility company supplying water and/or sewer to the
Leased Premises determines that an additional service fee, impact fee, and/or
assessment, or any other type of payment or penalty is necessary due to Tenant's
use and occupancy of the Building, nature of operation and/or consumption of
utilities, said expense shall be borne solely by the Tenant. Said expense shall
be paid promptly and any repairs requested by the utility company shall be
performed by Tenant immediately and without any delay.

    b. Landlord Controls Selection. Landlord has advised Tenant that presently
Excel Energy Company of Colorado ("Utility Service Provider") is the utility
company selected by Landlord to provide electricity and gas service for the
Building. Notwithstanding the foregoing, if permitted by Law, Landlord shall
have the right at any time and from time to time during the Lease Term to either
contract for service from a different company or companies providing electricity
and/or gas service (each such company shall hereinafter be referred to as an
("Alternative Service Provider") or continue to contract for service from the
Utility Service Provider.

    c. Tenant Shall Give Landlord Access. Tenant shall cooperate with Landlord,
Utility Service Provider, and any Alternative Service Provider at all times and,
as reasonably necessary, shall allow Landlord, Utility Service Provider, and any
Alternative Service Provider reasonable access to the Building's electric lines,
feeders, risers, wiring, gas lines, and any other machinery within the Premises.

    d. Landlord Not Responsible for Interruption of Service. Landlord shall in
no way be liable or responsible for any loss, damage, or expense that Tenant may
sustain or incur by reason of any change, failure, interference, disruption, or
defect in the supply or character of the electrical and/or gas energy furnished
to the Premises, or if the quantity or character of the electric and/or gas
energy supplied by the Utility Service Provider or any Alternate Service
Provider is no longer available or suitable for Tenant's requirements, and no
such change, failure, defect, unavailability, or unsuitability shall constitute
an actual or constructive eviction, in whole or in part, or entitle Tenant to
any abatement or diminution of rent, or relieve Tenant from any of its
obligations under the Lease Agreement.

provided for, Landlord shall keep and maintain the roof and exterior of the

prior to making any roof penetrations, which approval shall not be unreasonably

penetrations made by the Tenant and to use, , a licensed contractor to make such

an annual basis by the Landlord and shall be adjusted upwards or downwards
depending on the actual costs for the preceding twelve months. Tenant shall pay
monthly, commencing with the first month of the Lease Term, as additional rent
due under the terms hereof, a sum equal to Tenant's Prorata Share of the
estimated costs for said twelve (12) month period, divided by 12. The estimated

determine the actual costs of the foregoing expenses for the prior year and if
the actual costs are greater than the estimated costs, the Tenant shall pay its
Tenant's Prorata Share of the difference between the estimated costs and the

into and upon said Leased Premises that may be required therefore without the
same constituting an eviction of Tenant in whole or in part, and the rent
reserved shall in no way abate while such repairs, alterations, improvements or
additions are being made, by reason of loss or interruption of business of
Tenant or otherwise. During the six months prior to the expiration of the term
of this Lease Agreement or any renewal thereof, Landlord may, upon reasonable

tear. Notwithstanding the foregoing, Tenant shall be able to make changes to
voice and data networks which do not materially alter any fixture of the Leased
Premises without obtaining Landlord's consent. All such work shall be done in a
good and workmanlike manner and shall consist of new materials unless agreed to
otherwise by Landlord.

opportunity of being present when the signage is removed, or shall pre-approve
the manner and materials used to repair damage and close the holes caused by
removal.

20. RIGHT OF LANDLORD TO MAKE CHANGES AND ADDITIONS. Landlord reserves the right
at any time upon reasonable notice and such that Tenant's business is not

21. DAMAGE OR DESTRUCTION OF LEASED PREMISES. In the event the Leased Premises
and/or the Building of which the Leased Premises are a part shall be totally
destroyed by fire or other casualty or so badly damaged that, in the opinion of
Landlord, it is not feasible to repair or rebuild same, Landlord shall have the
right to terminate this Lease Agreement upon written notice to Tenant and if the
Landlord elects not to terminate the Lease Agreement, rent shall be abated until
the Leased Premises are reconstructed. If the Leased Premises are partially
damaged by fire or other casualty, , and said Leased Premises are rendered
untenable thereby, as determined by ordinary reason and prudence, an appropriate

                                  Page 6 of 19
<Page>

reduction of the rent shall be allowed for the unoccupied portion of the Leased
Premises until repair thereof shall be substantially completed. If the Landlord
elects to exercise the right herein vested in it to terminate this Lease
Agreement as a result of damage to or destruction of the Leased Premises or the
Building in which the Leased Premises are located, said election shall be made
by giving notice thereof to the Tenant within thirty (30) days after the date of
said damage or destruction.

If the Leased Premises are damaged by fire or other casualty such that Tenant
can not use the Leased Premises for the normal business purposes of Tenant under
Section 6 above, whether in part or in full, and the Landlord has not provided a
schedule for repair of the Leased Premises within forty five (45) days of such
event with further assurances that it will be able to restore the Leased
Premises, or is diligently working to restore the Leased Premises, to full
operating condition within a 360 day period of such event, then Tenant shall be
able to cancel this Lease Agreement upon written notice to the Landlord.

damage to the Leased Premises is due in whole or in part to the act, omission,
fault or negligence of Tenant, so long the Landlord is diligently working to
restore the Leased Premises.

22. GOVERNMENTAL ACQUISITION OF PROPERTY. Upon reasonable notice to Tenant, the
Landlord shall have complete freedom of negotiation and settlement of all
matters pertaining to the acquisition of the Leased Premises, the Building, the
Area, or any part thereof, by any governmental body or other person or entity
via the exercise of the power of eminent domain, it being understood and agreed
that any financial settlement made or compensation paid respecting said land or
improvements to be so taken, whether resulting from negotiation and agreement or
legal proceedings, shall be the exclusive property of Landlord, there being no
sharing whatsoever between Landlord and Tenant of any sum so paid. In the event
of any such taking, Landlord shall have the right to terminate this Lease
Agreement on the date possession is delivered to the condemning person or
authority. Such taking of the property shall not be a breach of this Lease
Agreement by Landlord nor give rise to any claims in Tenant for damages or
compensation from Landlord. Nothing herein contained shall be construed as
depriving the Tenant of the right to retain as its sole property any
compensation paid for any tangible personal property owned by the Tenant which
is taken in any such condemnation proceeding.

Landlord shall inform Tenant immediately of the pendency of any legal action or
proceeding under this Section 22. Notwithstanding the foregoing, Tenant shall be
entitled to seek, directly from the acquiring governmental authority an award
for Tenant's fixtures which are agreed to be Tenant's property in writing by the
Landlord in accord with Section 18 above, and any award for any of Tenant's
trade fixtures, equipment, personal property and relocation expenses.

pending as of the effective date of this Lease Agreement, and that if such
preexisting governmental actions are later discovered that this Lease Agreement
shall be void.

23. ASSIGNMENT OR SUBLETTING. Tenant may not assign this Lease Agreement, or
sublet the Leased Premises or any part thereof, without the written consent of
Landlord. No such assignment or subletting if approved by the Landlord shall
relieve Tenant of any of its obligations hereunder, and, the performance or
nonperformance of any of the covenants herein contained by subtenants shall be
considered as the performance or the nonperformance by the Tenant.

Premises in the manner described herein and that Tenant shall peaceably and
quietly have, hold, occupy and enjoy the Leased Premises during the term of the
Lease Agreement.

Premises through and across land and/or other improvements owned by Landlord.

such that any change shall not materially interfere with Tenant's ability to
conduct normal business.

26. SUBORDINATION. Subject to the provisions below, Tenant agrees that this
Lease Agreement shall be subordinate to any mortgages, trust deeds or ground
leases that may now exist or which may hereafter be placed upon said Leased
Premises and to any and all advances to be made thereunder, and to the interest
thereon, and all renewals, replacements and extensions thereof. Tenant shall
execute and deliver whatever instruments may be required for the above purposes,
and failing to do so within ten (10) days after demand in writing shall
constitute a material default under this Lease. Tenant shall in the event of the
sale or assignment of Landlord's interest in the Area or in the Building of
which the Leased Premises form a part, or in the event of any proceedings
brought for the foreclosure of or in the event of exercise of the power of sale

shall not be interfered with, nor shall the leasehold estate granted by this
Lease Agreement be affected in any other manner, in any foreclosure, deed in
lieu of foreclosure or any action or proceeding instituted under or in
connection with any mortgage, trust deed or ground lease for so long as Tenant
shall not be in default of any terms of this Lease Agreement. If Landlord is
unable to obtain a letter of non-disturbance, this shall not be a material
default under this Lease Agreement.

27. EASEMENTS. The Landlord shall have the right to grant any easement on, over,
under and above the Area for such purposes as Landlord determines, provided that
such easements do not materially interfere with Tenant's occupancy and ability
to conduct business and use of the Leased Premises, and upon reasonable notice.

28. INDEMNIFICATION AND WAIVER Except in the case of a breach or default in the
performance of any obligation under this Lease Agreement, each party shall
indemnify, defend and hold harmless the other party and nothing in this Lease
Agreement shall be construed as imposing any liability on them for any loss,
costs, expense (including reasonable attorney's fees), or any claims, suits,
actions or damages arising from the ownership, use, control or occupancy of any
portion of the Project including the Building, Common Areas and Premises unless
such loss, cost, expense, claim, suit or action is a result of or caused by the
negligent acts or omissions of such other party or its agents, servants,
employees, contractors, or invitees. Tenant shall not indemnify Landlord for
acts or failure to observe or comply with any of the rules by any other tenant
or occupant of the Building or Project that adversely affect Tenant's use and
occupancy in which Landlord has been put on notice of such adverse impact to
Tenant.

occupying any other part of the Area or by persons who are trespassers on or in
the Area, or for any loss or damage caused or resulting from the bursting,
stoppage, backing up or leaking of water, gas, electricity or sewers or caused
in any other manner whatsoever, unless such loss or damage is caused by or
results from the negligent acts of the Landlord, its agents or contractors.

30. INTEREST ON PAST DUE OBLIGATIONS. Any amount due to Landlord not paid when
due shall bear interest at two (2%) percent per month from due date until paid.
Payment of such interest shall not excuse or cure any default by Tenant under
this Lease Agreement. Tenant shall be granted a grace period of ten (10) days
from the date the obligation was initially due, and if Tenant does not pay
within the grace period interest shall accrue from the date the obligation was
initially due.

the parties hereto is and shall at all times remain that of Landlord and Tenant.

37. PARTIAL INVALIDITY. If any term, covenant or condition of this Lease
Agreement or the application thereof to any person or circumstance shall, to any
extent, be invalid or unenforceable, the remainder of this Lease Agreement or
the application of such term, covenant or condition to persons and circumstances
other than those to which it has been held invalid or unenforceable, shall not
be affected thereby, and each term, covenant and condition of this Lease
Agreement shall be valid and shall be enforced to the fullest extent permitted
by law.

38. DEFAULT-REMEDIES OF LANDLORD.
    a. The occurrence of any of the following events shall constitute a default
by Tenant under this Lease Agreement:

         i. Failure to make due and punctual payment of rent or any other
charges, assessments or amounts due or payable or required to be paid under this
Lease Agreement; or

         ii. Neglect or failure by Tenant to perform or observe, or any other
breach of, any other term, covenant or condition of this Lease Agreement; or

         iii. Adjudication of Tenant as bankrupt or insolvent, or filing by or
against Tenant of any petition in bankruptcy or for reorganization or for the
adoption of any arrangement under the Bankruptcy Code; application is made for
the appointment of receiver or conservator for Tenant's business or property; or
assignment by Tenant is made of its property for the benefit of its creditors;
or Tenant's interest in this Lease Agreement or any substantial amount of
Tenant's other real or personal property is levied or executed upon by process
of law; or

         iv. Petition or other proceeding is made by or against Tenant for its

or

         v. Abandonment of the Leased Premises, by Tenant for a period of time

                                  Page 8 of 19
<Page>

days.

     b. If Tenant shall default in the payment of rent or in the keeping of any
of the terms, covenants or conditions of this Lease Agreement to be kept and/or
performed by Tenant or shall otherwise commit any event of default as defined
above, Landlord may upon the expiration of any applicable cure, immediately, or
at any time thereafter, reenter the Leased Premises, remove all persons and
property therefrom, without being liable to indictment, prosecution for damage
therefore, or for forcible entry and detainer and repossess and enjoy the Leased
Premises, together with all additions thereto or alterations and improvements
thereof. Landlord may, at its option, at any time and from time to time
thereafter, relet the Leased Premises or any part thereof for the account of
Tenant or otherwise, and receive and collect the rents therefore and apply the
same first to the payment of such expenses as Landlord may have incurred in
recovering possession and for putting the same in good order and condition for
rerental, and expense, commissions and charges paid by Landlord in reletting the
Leased Premises. Any such reletting may be for the remainder of the term of this
Lease Agreement or for a longer or shorter period. In lieu of reletting such
Leased Premises, Landlord may occupy the same or cause the same to be occupied
by others. Whether or not the Leased Premises or any part thereof be relet,
Tenant shall pay the Landlord the rent and all other charges required to be paid
by Tenant up to the time of the expiration of this Lease Agreement or such
recovered possession, as the case may be and thereafter, Tenant, if required by
Landlord, shall pay to Landlord until the end of the term of this Lease
Agreement, the equivalent of the amount of all rent reserved herein and all
other charges required to be paid by Tenant, less the net amount received by
Landlord for such reletting, if any, unless waived by written notice from
Landlord to Tenant. No action by Landlord to obtain possession of the Leased
Premises and/or to recover any amount due to Landlord hereunder shall be taken
as a waiver of Landlord's right to require full and complete performance by
Tenant of all terms hereof, including payment of all amounts due hereunder or as
an election on the part of Landlord to terminate this Lease Agreement. If the
Leased Premises shall be reoccupied by Landlord, then, from and after the date
of repossession, Tenant shall be discharged of any obligations to Landlord under
the provisions hereof for the payment of rent. If the Leased Premises are
reoccupied by the Landlord pursuant hereto, and regardless of whether the Leased
Premises shall be relet or possessed by Landlord, all fixtures, additions,
furniture, and the like then on the Leased Premises may be retained by Landlord.
In the event Tenant is in default under the terms hereof and, by the sole
determination of Landlord, has abandoned the Leased Premises, Landlord shall
have the right to remove all the Tenant's property from the Leased Premises and
dispose of said property in such a manner as determined best by Landlord, at the
sole cost and expense of Tenant and without liability of Landlord for the
actions so taken and without liability on the part of Landlord for any action so
taken.

     c. In the event an assignment of Tenant's business or property shall be
made for the benefit of creditors, or, if the Tenant's leasehold interest under
the terms of this Lease Agreement shall be levied upon by execution or seized by
virtue of any writ of any court of law, or, if application be made for the
appointment of a receiver for the business or property of Tenant, or, if a
petition in bankruptcy shall be filed by or against Tenant, then and in any such
case, at Landlord's option, with or without notice, Landlord may terminate this
Lease Agreement and immediately retake possession of the Leased Premises without
the same working any forfeiture of the obligations of Tenant hereunder .

     d. In addition to all rights and remedies granted to Landlord by the terms
hereof, Landlord shall have available any and all rights and remedies available
at law or in equity, or under the statutes of the State of Colorado. No remedy
herein or otherwise conferred upon or reserved to Landlord shall be considered
exclusive of any other remedy but shall be cumulative and shall be in addition
to every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute. Further, all powers and remedies given by this Lease
Agreement to Landlord may be exercised, from time to time, and as often as
occasion may arise or as may be deemed expedient. No delay or omission of
Landlord to exercise any right or power arising from any default shall impair
any such right or power or shall be considered to be a waiver of any such
default or acquiescence thereof. The acceptance of rent by Landlord shall not be
deemed to be a waiver of any breach of any of the covenants herein contained or
of any of the rights of Landlord to any remedies herein given.

     e. If Tenant shall, for any reason, vacate the Leased Premises before the
end of the Lease Agreement and more than 30 days late in the payment of rental
payments, landlord shall have the right to accelerate rental payments and any
and all future rent payments due during the course of the Lease Term shall
become immediately payable in full to the Landlord, except that Tenant shall
have the right, in accord with the provisions of Article 23 above, to obtain a
sublessee acceptable to the Landlord for the remainder of the Lease Term, and
Landlord's consent to any qualified sublessee shall not be unreasonably
withheld. Amount received under any such sublease shall be creditable against
Tenant's obligations to pay rent and shall not remove the primary obligation of
the Tenant to pay the rent.

39. LEGAL PROCEEDINGS-RESPONSIBILITIES. In the event of proceeding at law or in
equity by either party hereto, the defaulting party shall pay all costs and
expenses, including all reasonable attorney's fees incurred by the
non-defaulting party in pursuing such remedy, if such non-defaulting party is
awarded substantially the relief requested.

40. ADMINISTRATIVE CHARGES. In the event any check, bank draft or negotiable
instrument given for any money payment hereunder shall be dishonored at any time
and from time to time, for any reason whatsoever not attributable to Landlord,
Landlord shall be entitled, in addition to any other remedy that may be
available, (1) to make an administrative charge of $100.00 or three times the
face value of the check, bank draft or negotiable instrument, whichever is
smaller, and (2) at Landlord's sole option, if Tenant's financial instrument has
been returned more than two (2) times in any consecutive twelve (12) month
period, to require Tenant to make all future rental payments in cash or cashiers
check.

41 LANDLORD HAZARDOUS MATERIALS AND ENVIRONMENTAL CONSIDERATIONS.

     a. Tenant shall not be held liable, and Landlord agrees to indemnify and
hold Tenant harmless, from and against any action brought with regards to any

agency or political subdivision relating to Hazardous Materials Laws or any UST
Laws, or violation thereof affecting the Common Area or Leased Premises and all
communications to or from any other person relation to Hazardous Materials Laws
or any UST Laws, or violation thereof affecting the Common Areas or Leased
Premises. Without limiting the foregoing, Landlord also covenants and agrees to
provide Tenant access to all reports prepared by or on behalf of Landlord with
respect to compliance by Landlord with Hazardous Materials Laws or any UST Laws
insofar as they pertain to the Common Areas or Leased Premises or the operations

advise Tenant in writing of (i) any and all claims made or threatened by any
governmental authority, political subdivision or any private third party with
respect to any alleged violation of any applicable Hazardous Materials Laws or
of any other claim of liability arising out of or related to Hazardous

or (iv).

     d. Tenant shall have the right to join and participate in, as a party if it
so elects, any legal proceedings or actions initiated in connection with any
asserted violation of applicable Hazardous Materials by Landlord, and Landlord
shall pay all attorney's fees, cost and expenses associated therewith so long as
Tenant agrees to be represented by counsel of Landlord's choosing and that
Landlord shall control the settlement of any claim, subject to Tenant's consent
to any such settlement which consent shall not be unreasonably withheld. If
Tenant chooses to be represented by separate counsel Tenant shall pay all
attorney's fees, costs and expenses associated therewith.

     Landlord represents and warrants, to the best of its information, belief
and knowledge, that there are no Preexisting Violations of any and all Hazardous
Materials Laws, UST Laws and environmental and occupation safety and health
rules, laws and regulations as of the effective date of this Lease Agreement.

     e. Nothing in this Article 41 shall relieve either party of any liability

and environmental and occupation safety and health rules laws and regulations
which ordinarily attach to that party by operation of law.

     f. Subject to applicable laws, all obligations of Landlord under this
Section 41 shall survive and continue after the expiration of the term of this
Lease Agreement or the earlier termination of this Lease Agreement for any
reason.

42. TENANT HAZARDOUS MATERIALS AND ENVIRONMENTAL CONSIDERATIONS.

     a. The provisions of this Article 42 shall apply only to Tenant and its
agents, employees, contractors, licensees and invitees, use, handling, storage
and disposal of Hazardous Materials on or about the Leased Premises during the
Lease Term, and any extensions of the Lease Term (Tenant's Acts).

     b. Tenant covenants and agrees that Tenant and its agents, employees,
contractors, licensees and invitees will comply with all Hazardous Materials
Laws. Without limiting the foregoing, in the event Tenant generates any
Hazardous Materials on or about the Leased Premises, Tenant covenants and agrees
that it will use, handle, store and dispose of such Hazardous Materials in full
compliance with all Hazardous Materials Laws. The generation of any Hazardous
Materials shall in no way interfere with (i) any other tenant's or adjoining
landowner's ability to use its premises, or (ii) the integrity of Landlord's
premises. All Hazardous Materials, vapors, chemicals or other pollutants shall
be handled in an environment controlled by appropriately designed and installed
air-handling or other appropriate equipment which shall be maintained and
operated at Tenant's expense at all times during the term hereof, which
equipment shall meet or exceed the stricter of standards imposed by any
applicable Hazardous Materials Laws or any applicable industry standards. Any
such air-handling or other equipment coming into contact with Hazardous
Materials shall be removed by Tenant upon termination or expiration of this
Lease if Landlord so requests.

     c. Without limiting the foregoing, in the event Tenant stores any Hazardous
Materials on the Leased Premises (or elsewhere if such Hazardous Materials were
generated on or transported from the Leased Premises), Tenant covenants and
agrees that such storage shall be in compliance with all applicable Hazardous
Materials Laws. Should it be necessary to store any Hazardous Materials outside
the Building on the Leased Premises, Tenant shall do so in a manner designed to
prevent contamination of the air, ground or water in, on or surrounding the
Leased Premises.

     d. Without limiting the foregoing, Tenant covenants and agrees that any
transportation of Hazardous Materials to or from the Leased Premises shall be
accomplished in full compliance with all applicable Hazardous Materials Laws.
Landlord shall be given full access to any and all records, bills of lading,
manifests, and other information or records maintained by Tenant in connection
with such transportation,

     e. Tenant covenants and agrees to inform Landlord at any time during the
term of this Lease Agreement of any significant changes in the scope or type of
Hazardous Materials it intends to use, generate, manufacture, handle, store or
dispose of on, about or from the Leased Premises, and of any significant changes
in the scope of activities conducted by Tenant on or in the Leased Premises.

     f. Tenant shall promptly take any and all necessary preventive and/or
remedial action in response to any spills or releases of Hazardous Materials on,
under or about the Leased Premises. Tenant shall take such preventive or
remedial action in good faith so as to minimize any impairment to the Leased
Premises and any adjoining premises. In the event Tenant undertakes any remedial
action with respect to any Hazardous Materials on, under or about the Leased
Premises, Tenant shall conduct and complete such remedial action (i) in
compliance with all applicable Hazardous Materials Laws; (ii) to the reasonable
satisfaction of Landlord; and (iii) in accordance with the lawful orders and
directives of all federal, state and local governmental authorities or political
subdivisions asserting jurisdiction over the Leased Premises.

     g. Upon expiration or termination of this Lease Agreement and/or vacation
of the Leased Premises, Tenant covenants and agrees that it shall properly
remove and dispose of all Hazardous Materials from the Leased Premises and
thereafter provide Landlord with an environmental audit report, prepared by a
professional consultant reasonably satisfactory to Landlord and at Tenant's sole
expense, certifying that the Leased Premises and the surrounding areas have not
been subjected to environmental harm brought about by Tenant's use and occupancy
of the Leased Premises. If the initial report does not adequately certify that
the Leased Premises and surrounding areas are not subject to environmental harm,
Tenant shall, at Tenant's expense, undertake such remediation and mitigation
actions as are appropriate and reasonably acceptable to Landlord and shall
provide an updated or amended report by such professional consultant then
certifying that the Leased Premises and surrounding areas are no longer subject
to environmental harm brought by Tenant's use and occupancy of the Leased
Premises. Landlord shall grant to Tenant and its agents or contractors such
access to the Leased Premises as is reasonably necessary to accomplish such
removal and prepare such audit. If such removal is not accomplished prior to the
expiration of the Lease term, Tenant shall be obligated to pay rent to Landlord
in an amount of One Hundred Ten (110%) of the last month's rent.

     h. Landlord shall have the right to join and participate in, as a party if
it so elects, any legal proceedings or actions initiated in connection with any
asserted violation of applicable Hazardous Materials Laws or UST Laws by Tenant,
and Tenant shall pay all attorney's fees, cost and expenses associated therewith
so long as Landlord agrees to be represented by counsel of Tenant's choosing and
that Tenant shall control the settlement of any claim, subject to Landlord's
consent to any such settlement which consent shall not be unreasonably withheld.
If Landlord chooses to be represented by separate counsel Landlord shall pay all
attorney's fees, costs and expenses associated therewith.

     Tenant shall and hereby covenants and agrees to indemnify, defend and hold
Landlord harmless from and against any and all suits, actions, legal or
administrative proceedings, demands, claims, judgments, damages, penalties,
fines, costs, liabilities, expenses or losses and Tenant shall pay all
attorney's fees, cost and expenses associated therewith so long as Landlord
agrees to be represented by counsel of Tenant's choosing and that Tenant shall
control the settlement of any claim, subject to Landlord's consent to any such
settlement which consent shall not be unreasonably withheld which arise during
or after the Lease Term as caused or permitted by Tenant's Acts in connection
with (i) breach by Tenant of any of its agreements or covenants contained in
this Section entitled "Hazardous Materials and Environmental Considerations";
(ii) the presence of Hazardous Materials on the Leased Premises caused or
permitted by Tenant (or its agents, employees, contractors, licensees or
invitees); (iii) personal injury or property damage to any person or property
(including, without limitation, the Leased Premises) resulting from the use,
storage, generation, manufacture, disposal or transportation of Hazardous
Materials by Tenant (or its agents, employees, contractors, licensees or
invitees) in, on, under or from the Leased Premises; (iv) any violation or claim
of violation by Tenant (or its agents, employees, contractors, licensees or
invitees) of any Hazardous Materials Laws; (v) costs incurred in connection with
any investigation of site conditions or any cleanup, remedial, removal or
restoration work or action caused or permitted by Tenant's acts and required by
any federal, state or local governmental agency, political subdivision or court
order (or pursuant to settlement of any such proceedings); (vi) imposition of
any lien for the recovery of any costs for environmental cleanup or other
response costs caused or permitted by Tenant's Acts and related to the release
or threatened release of Hazardous Materials in, on or about the Leased
Premises. Without limiting the foregoing, if the presence of any Hazardous
Materials on the Leased Premises caused or permitted by Tenant's Acts results in
any contamination of the Leased Premises, Tenant shall promptly take all
actions, at its sole expense, as are necessary to return the Leased Premises to
the condition existing prior to the introduction of any such Hazardous Materials
to the Leased Premises; provided that Landlord's approval of such actions shall
first be obtained, which approval shall not be unreasonably withheld so long as
such actions would not potentially have any material adverse long-term or
short-term effect on the Leased Premises. Tenant understands and agrees that its
liability to Landlord shall arise upon the earlier to occur of (i) discovery of
any Hazardous Materials on, under or about the Leased Premises caused or
permitted by Tenant's Acts; or (ii) the institution of any claim asserting the
violation of any Hazardous Materials Laws or other indemnified matter caused or
permitted by Tenant's Acts, and not upon the realization of loss or damage, and
Tenant agrees to pay to Landlord from time to time, immediately upon Landlord's
request, an amount equal to such expenses, as reasonably determined by landlord.
All agreements of indemnification of Landlord by Tenant shall also accrue to the
benefit of the employees, agents, officers, directors and partners of Landlord.

     i. "Hazardous Materials" shall mean (i) any oil, flammable substances,
explosives, radioactive materials, hazardous wastes or substances, toxic wastes
or substances, or any other materials or pollutants which pose a hazard to the

     j. "Hazardous Materials Laws" shall mean any federal, state or local laws,
ordinances, codes, rules, regulations, directives or policies (including, but
not limited to, those laws specified in subparagraph H, above) relating to the
environment, health or safety, any Hazardous Materials (including, without
limitation, the use, handling, transportation, production, disposal, discharge
or storage thereof) or to industrial hygiene or the environmental conditions on,
under or about the Leased Premises (including, without limitation, soil and
ground water conditions). The term "Hazardous Materials Laws" shall also be
deemed to include any future such laws, ordinances, codes, rules, regulations,
directives or policies as the same may be adopted from time to time during the
term of this Lease Agreement, and any amendments to any currently existing or
subsequently adopted Hazardous Materials Laws.

     k. Tenant covenants and agrees that it shall comply with all federal, state
and local laws, rules, regulations and/or

                                  Page 11 of 19

ordinances governing the installation, operation and maintenance of above ground
and underground storage tanks, including, without limitation, all standards
concerning construction, installation, upgrades, operations, repairs, common
maintenance, monitoring, leak detection, inspection, testing, record keeping and
recording imposed by law (collectively "UST Laws"). Tenant further covenants and
agrees that it shall not install any above ground or underground tank on the
Leased Premises without obtaining the prior written consent of Landlord, such
consent not to be unreasonably withheld.

     Tenant shall provide to Landlord, upon reasonable request, access to any
and all records required to be maintained pursuant to law, including, without
limitation, registrations, monitoring records, inventory reconciliation record,
chemical and physical analyses, tank tests and reports required to be provided
to any governmental agency or political subdivision.

     At all times during and following installation of any above ground or

requirements of the Environmental Protection Agency, the Colorado Department of
Health or any other federal, state or local governmental body with jurisdiction
over the Leased Premises, which compliance shall including, but need not be

Tenant.

     Upon termination of this Lease Agreement (unless by purchase of the Leased
Premises by Tenant) and/or vacation of the Leased Premises, Tenant covenants and
agrees that it shall properly remove all above ground and underground storage
tanks from the Leased Premises, unless other methods of insuring compliance with
all applicable UST Laws are recommended by a professional consultant and
accepted by Landlord, and thereafter provide Landlord with an environmental
audit report, prepared by a professional consultant reasonably satisfactory to
Landlord and at Tenant's sole expense, certifying that the Leased Premises and
the surrounding areas have not been subjected to environmental harm caused by,
arising out of, or in connection with Tenant's installation, use, maintenance or
removal of above ground and underground storage tanks on or from the Leased
Premises. Landlord shall grant to Tenant and its agents or contractors such
access to the Leased Premises as is reasonably necessary to accomplish such
removal and prepare such audit. If such removal is not accomplished prior to the
expiration of the Lease term, Tenant shall be obligated to pay rent to Landlord
in an amount of One Hundred Ten (110%) of the last month's rent.

     Tenant shall indemnify, defend and hold Landlord harmless from any and all
claims, judgments, damages, penalties, fines, costs, liabilities or losses which
arise during or after the Lease Term as a result of breach by Tenant under this
Section 42 k. and Tenant shall pay all attorney's fees, cost and expenses
associated therewith so long as Landlord agrees to be represented by counsel of
Tenant's choosing and that Tenant shall control the settlement of any claim,
subject to Landlord's consent to any such settlement which consent shall not be
unreasonably withheld. This indemnification of Landlord by Tenant includes,
without limitation, any costs incurred in connection with any investigation of
site conditions or any cleanup, remedial, removal or restoration work required
by any federal, state or local governmental agency or political subdivision
arising out of or in connection with the use or existence of above ground or
underground storage tanks on the Leased Premises. Without limiting the
foregoing, if the presence of above ground or underground storage tanks on the
Leased Premises installed, used or operated by Tenant results in any
contamination of the Leased Premises not due to a Preexisting Violation, Tenant
shall promptly take all actions at its sole expense, as are necessary to return
the Leased Premises to the condition required by the relevant governmental
authorities with regards to such contamination; provided that Landlord's
approval of such actions shall first be obtained, which approval shall not be
unreasonably withheld. All agreements of indemnification of Landlord by Tenant
shall also accrue to the benefit of the employees, agents, officers, directors
and/or partners of Landlord.

     l. Tenant covenants and agrees that it shall allow Landlord's employees or
agents upon reasonable notice and such that Tenant's business is not
unreasonably interrupted rights of access to inspect the Leased Premises and the
surrounding area to conduct such tests as Landlord deems necessary (at
Landlord's expense) and to otherwise confirm that Tenant is in full compliance
with all applicable Hazardous Materials Laws and/or UST Laws. If any such test
discloses that Tenant is not in compliance with any such laws, Tenant shall, in
addition to all other obligations hereunder, reimburse Landlord for the cost of
conducting such tests.

     m. Tenant covenants and agrees to provide to Landlord, upon reasonable
notice and such that Tenant's business is not materially interfered with, access
to any and all communications to or from any federal, state or local
governmental authority or agency or political subdivision relating to Hazardous
Materials Laws or any UST Laws, or violation thereof affecting the Leased
Premises and all communications to or from any other person relation to
Hazardous Materials Laws or any UST Laws, or violation thereof affecting the
Leased Premises. Without limiting the foregoing, Tenant also covenants and
agrees to provide Landlord reports prepared by or on behalf of Tenant with
respect to compliance by Tenant with Hazardous Materials Laws or any UST Laws
insofar as they pertain to the Leased Premises or the operations conducted by
Tenant thereon, as well any "Material Safety Data Sheets" issued from time to
time in connection with any Hazardous Materials used, generated, handled, stored
or disposed of on, about or from the Leased Premises.

     n. Tenant covenants and agrees to immediately advise Landlord in writing of
(i) any and all claims made or threatened by any governmental authority,
political subdivision or any private third party with respect to any alleged
violation of any applicable Hazardous Materials Laws or of any other claim of
liability arising out of or related to Hazardous Materials; (ii) Tenant's
discovery of any occurrence or condition in, on or about the Leased Premises,
which constitutes or may constitute a violation of any applicable Hazardous
Materials Laws or breach of any term or condition of this Lease; (iii) any and
all claims made or threatened by any governmental authority, political
subdivision or any private third party with respect to any alleged violation of
any UST Laws or of any other liability arising out of or in connection with
Tenant's installation, use or maintenance of above ground or underground storage
tanks on or under the Leased Premises; (iv) Tenant's discovery of any occurrence
of condition in, on or about the Leased Premises, which constitutes a violation
of any such laws; and (v) any remedial action taken or proposed to be taken by
Tenant in response to any claim or discovery described in subparagraphs (i),
(ii), (iii) or (iv).

     o. If Tenant fails to comply with any of its foregoing obligations with
respect to Hazardous Materials, Landlord may, in its reasonable discretion,
cause the removal (or other cleanup or remediation acceptable to Landlord) of
any Hazardous Materials from the Leased Premises. The cost of any such removal,
remediation and other cleanup, including, without limitation, transportation and
storage costs, costs of consultants and professionals, and any other costs or
expenses in any way associated with such removal, remediation or cleanup (and
compliance of any applicable Hazardous Materials Laws in connection with same)
shall constitute additional rent under this Lease Agreement, and such costs and
expenses shall become due and payable upon demand by Landlord. Tenant shall
provide Landlord, or its agents, contractors and employees, upon reasonable
notice and such that Tenant's business is not unreasonably interrupted access to
the Leased Premises for the purpose of removing or otherwise cleaning up any
Hazardous Materials upon demand.

                                  Page 12 of 19
<Page>

Landlord, however, shall have no affirmative obligation to remove, remediate or
otherwise cleanup any Hazardous Materials or otherwise deal with any Hazardous
Materials in, on or about the Leased Premises, and this Lease Agreement shall
not be construed as creating any such obligation.

     p. Nothing in this Article 42 shall relieve either party of any liability
in contravention of any applicable environmental and occupation safety and
health rules laws and regulations which ordinarily attach to that party by
operation of law.

     r. Subject to applicable laws, all obligations of Tenant under this Section
42 shall survive and continue after the expiration of the term of this Lease

Tenant's plans for tenant finish shall be submitted to Landlord in writing.
Landlord shall provide a response thereto within five (5) business days after
receipt of the written submission. In the event no response is received by

2. Tenant Construction Obligations
          Tenant shall perform all improvements to the Leased premises at its

subtenants to the Leased Premises; and the Tenant agrees to hold the Landlord
free and harmless against all such liens and claims of liens for labor and
materials, or either of them, filed against the Leased Premises, property, or
any part thereof, and from and against any expense and liability in connection
therewith. The Tenant shall, however, have the right to contest any mechanic's
liens or claims filed against the Leased Premises, provided the Tenant shall
diligently prosecute any such contest and at all times effectively stay or
prevent any sale of the Leased Premises under execution or otherwise, and pay or

been furnished at the Tenant's request in, on, or about the Leased Premises, and
to indemnify the Landlord against any lien or claim of lien attached to or upon
the Leased Premises or any part thereof by reason of any act or omission on the
Tenant's part; but nothing contained in this Lease Agreement, however, is

* Landlord and Tenant will attempt to agree upon a Fair Market Rental Value of
the Leased Premises (expressed on a dollar per square foot basis) as determined
by comparison to parcels of similar size property located in or near the City of
Boulder, Colorado, having comparable development, use and density capability and
such other characteristics as may be deemed relevant by a subject appraiser
whose selection is outlined herein.

Landlord shall select an independent MAI real estate appraiser with at least ten
(10) years' experience in appraising commercial real property in the City of
Boulder, Colorado (a "Qualified Appraiser"). The Qualified Appraiser selected by
the Landlord shall be referred to as the "Landlords Appraiser". Within thirty
(30) days of being selected by the Landlord, the Landlord's appraiser shall
determine the Fair Market Rental Value of the Leased Premises in accordance with
the appraisal standards set forth above and shall immediately give the Landlord
and the Tenant written notification of his determination.

If the Tenant agrees with the Landlord's Appraiser's determination by
multiplying the Fair Market Rental Value, then the Base Monthly Rent shall be
determined by multiplying the Fair Market Rental Value by 33,673 and the new
Base Monthly Rental shall become effective beginning with the first month of the
Option Term. If the Tenant does not agree with the Landlord's Appraiser's
determination of Fair Market Rental Value, the Tenant shall have the right to
select its own Qualified Appraiser its own Qualified Appraiser to determine the
Fair Market Rental Value. If the Tenant does elect to appoint a Qualified
Appraiser, (the Tenant's Appraiser"), the Tenant shall select the Tenant's
Appraiser within thirty (30) business days after receiving the Landlord's
Appraiser's Determination of Fair Market Rental Value. The Tenant's Appraiser
shall make his own determination if the Fair Market Rental Value in accordance
with the provisions set forth above, within thirty (30) business days of being
selected by the Tenant and shall immediately give the Landlord and the Tenant
written notice of his determination.

If the Fair Market Rental Value as determined by the Landlord's Appraiser and
the Tenant's Appraiser, respectively, differ by an amount which is equal to or
less than five percent (5%) of the Fair Market Rental Value determined by the
Landlord's Appraiser, then the arithmetic mean of the two Fair Market Rental
Values shall constitute the fair Market Rental Value used to calculate the new
Base Monthly Rental which will be in effect for the Option Term. If the Fair
Market Rental Value determined by the Landlord's Appraiser and the Tenant's
Appraiser's determination of the Fair Market Rental Value differ by more than
five percent (5%), the Landlord's Appraiser and the Tenant's Appraiser shall
agree upon and select a third Qualified appraiser who shall be independent of
and have no prior or existing affiliation or relationship with either the
Landlord or the Tenant (the "Independent Appraiser"). Within ten (10) business
days of being appointed, the Independent Appraiser shall, after exercising his
best professional judgement, choose either the Landlord's Appraiser's or the
Tenant's Appraiser's determination of the Fair Market Rental Value which the
judgement, best represents the Fair Market Rental Value at that point in time.
Upon making such a selection, the Independent Appraiser shall immediately give
the Landlord and the Tenant written notice of this selection of the Fair Market
Rental Value. The Fair Market Rental Value selected by the Independent Appraiser
shall be used to calculate the new Base Monthly Rental which will be in effect
during the Extension Option, and such selection by the Independent appraiser
shall be binding and conclusive upon the Landlord and the Tenant.

The Landlord and Tenant shall share all Appraisal fees required hereunder
equally.
