        THIS LOCK-UP AND REGISTRATION RIGHTS AGREEMENT (this "Agreement") is
entered into as of _______, 2000 (the "Effective Date") by and between
MEDIBUY.COM, INC., a Delaware corporation (the "Company") and ____________
("Stockholder").

        WHEREAS, the Company, Sapphire Acquisition Corp., a Delaware corporation
and a wholly owned subsidiary of the Company, Premier Health Exchange, LLC, a
Delaware limited liability company ("Premier") and Premier Purchasing Partners,
L.P., a California limited partnership (the "Major Member") are parties to that
certain Agreement and Plan of Merger dated as of March 6, 2000 (the "Merger
Agreement"); and

        WHEREAS, in connection with the Merger Agreement, the Company shall
issue to the Stockholder, and the Stockholder shall acquire from the Company,
shares of the Company's common stock, $.001 par value ("Common Stock"), on the
terms and subject to the conditions set forth in the Merger Agreement.

        NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual covenants and agreements contained herein, the parties hereto, intending
to be legally bound, do hereby agree as follows:

1.      LOCK-UP

        Except as permitted by the last sentence of this Section 1 or as
consented to by the Company, but notwithstanding any other provision of this
Agreement or the Investor Rights Agreement (as defined in Section 2), the
Stockholder hereby agrees that the Stockholder will not, directly or indirectly,
for a period of one year after the consummation of the Company's Initial Public
Offering (as defined in the Investor Rights Agreement), (1) sell, transfer or
otherwise dispose of, or offer, contract or grant an option to sell, transfer or
otherwise dispose of, or make any short sales of, or require the Company to file
with the Commission a registration statement under the Securities Act of 1933,
as amended, to register, any shares of Common Stock of the Company or securities
convertible into or exchangeble for Common Stock of the Company or warrants or
other rights to acquire shares of Common Stock of the Company of which the
undersigned is now, or may in the future become, the beneficial owner (within
the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act") (other than pursuant to employee stock option plans of the
Company or in connection with other employee incentive compensation arrangements
with the Company), or (2) enter into any swap or similar agreement that
transfers, in whole or in part, any of the economic consequences of the
ownership of the Common Stock of the Company, whether any such transaction
described in clause (1) or (2) above is to be settled by delivery of Common
Stock of the Company or such other securities, in cash or otherwise, otherwise
than (i) as a bona fide gift or gifts, (ii) by will or intestacy or to a trust
the beneficiaries of which are the undersigned or members of his or her family,
or (iii) as a distribution to limited partners, members or shareholders of the
Stockholder or the affiliates of Stockholder, provided that such gift, transfer
or distribution shall be conditioned upon the donee's, transferee's or
distributee's execution and delivery to the Company of a Lock-Up and
Registration Rights Agreement containing terms identical to the terms contained
herein. Notwithstanding anything contained herein to the contrary, in the event

<PAGE>   2

Stockholder requests, in accordance with the provisions of Sections 2.3 or 2.5
of the Investor Rights Agreement (as defined in Section 2(a) of this Agreement),
that the Company register shares of common stock of the Company held by the
Stockholder on either a Company-initiated registration statement filed pursuant
to Section 2.3 of the Investor Rights Agreement or a Form S-3 registration
statement filed pursuant to Section 2.5 of the Investor Rights Agreement, then
in such event the restrictions set forth in the immediately preceding sentence
shall lapse and shall not be applicable with respect to those shares of Common
Stock of the Company included on such Company-initiated registration statement
or Form S-3 registration statement. Additionally, to the extent Stockholder is
the holder of options to purchase shares of Common Stock of the Company which
are subject to the terms of this Section 1, and Stockholder is required to
exercise such options prior to the first anniversary of the consummation of the
Company's Initial Public Offering or otherwise lose the right to exercise such
options, then, in such event, the restrictions set forth in the first sentence
of this Section 1 shall lapse and shall not be applicable with respect to, and
only with respect to, that number of shares of Common Stock of the Company
having an aggregate fair market value on the date of the exercise of such option
equal to the aggregate amount of the federal, state and local tax liability
arising out of such exercise.

2.      REGISTRATION RIGHTS

               (a) Subject to the terms and provisions of this Agreement, the
Company agrees that the Stockholder shall be entitled to the registration rights
set forth in Section 2 ("Restrictions on Transferability of Securities;
Registration Rights") (collectively, the "Registration Rights") of that certain
Second Amended and Restated Investor Rights Agreement dated as of January 7,
2000, by and among the Company and certain of its stockholders (the "Investor
Rights Agreement"), on a pari passu basis with the other Holders (as defined in
the Investor Rights Agreement). The Stockholder's Registration Rights hereunder
shall be automatically amended to the extent Section 2 (other than Section 2.2)
of the Investor Rights Agreement is amended from time to time in accordance with
Section 5.4 of the Investor Rights Agreement; provided however, that no such
amendment shall be made that materially adversely affects Stockholder's
registration rights under the Investor Rights Agreement without the consent of
Stockholder.

               (b) The shares of Common Stock of the Company received by the
Stockholder pursuant to the Merger Agreement (the "Merger Shares") and any
shares acquired upon the exercise of Company Warrants (as defined in the Merger
Agreement) shall be deemed to be "Registrable Securities" (notwithstanding that
any of such securities have been registered) and the Stockholder shall be deemed
to be a "Holder" solely for the purposes of Section 2 (other than Section 2.2)
of the Investor Rights Agreement; provided, however, that (i) the Stockholder
shall not be entitled to a demand registration or any other rights (except as
provided herein) granted under Section 2.2 of the Investor Rights Agreement,
(ii) the Merger Shares shall not be included in the determination of any
threshold requirement for a demand registration (other than on Form S-3) under
Section 2.2(a) of the Investor Rights Agreement, (iii) the Stockholder shall not
be deemed to be a "Significant Holder" under the Investor Rights Agreement, and
(iv) the Stockholder shall not be entitled to any other rights as a Holder or
otherwise under the Investor Rights Agreement for any purpose other than the
Registration Rights. The Merger Shares shall be included in the determination of
any threshold requirement for registration rights on Form S-3

                                       2.

2.2(a)(i) thereof).

               (c) Stockholder acknowledges that it has previously received a
copy of the Investor Rights Agreement. The Company will notify the Stockholder
of any amendment of the Investor Rights Agreement and deliver to the Stockholder
a copy of any amendment promptly following any such amendment.

               (d) The Stockholder acknowledges and agrees that, as a "Holder",
it shall be subject to and bound by the provisions of Section 2 (other than
Section 2.2, except as provided herein) of the Investor Rights Agreement,
including, without limitation, provisions relating to indemnification,
restrictions on transfer and market stand-off provisions.

3.      STANDSTILL

               (a) During the period beginning on the Effective Date until the

Company's Common Stock pursuant to a registration statement filed under the
Securities Act of 1933, as amended (the "Standstill Period"), the Stockholder
will not, in any manner, directly or indirectly:

                      (i) make, effect, initiate, cause or participate in (1)
any acquisition of beneficial ownership of any securities of the Company or any
securities of any subsidiary or other affiliate of the Company (other than the
Company's securities which Stockholder has the right to acquire from Dave
Mawhinney pursuant to agreements between Stockholder and Dave Mawhinney in
effect as of the date of this Agreement), (2) any acquisition of any assets of
the Company or any assets of any subsidiary or other affiliate of the Company,
(3) any tender offer, exchange offer, merger, business combination,
recapitalization, restructuring, liquidation, dissolution or extraordinary
transaction involving the Company or any subsidiary or other affiliate of the
Company, or involving any securities or assets of the Company or any securities
or assets of any subsidiary or other affiliate of the Company, or (4) any
"solicitation" of "proxies" (as those terms are used in the proxy rules of the
Securities and Exchange Commission) or consents with respect to any securities
of the Company; or

                      (ii) form, join or participate in a "group" (as defined in
the Securities Exchange Act of 1934 and the rules promulgated thereunder) with
respect to the beneficial ownership of any securities of the Company.

               (b) Notwithstanding any provision of Section 3(a) to the
contrary, the provisions of Section 3(a) shall terminate in the event (i) any
Person or "group" (as defined in the Exchange Act, and the rules promulgated
thereunder) shall have commenced an Acquisition Transaction (as defined below),
or (ii) the board of directors of the Company shall have endorsed, approved,
recommended, or resolved to endorse, approve or recommend an Acquisition
Transaction. All of the provisions of Section 3(a) shall be reinstated and shall
apply in full force according to their terms in the event that: (x) if the
provisions of Section 3(a) shall have terminated as the result of a tender
offer, such tender offer (as originally made or as amended or modified) shall
have terminated (without closing) prior to the commencement of a tender offer by
the Stockholder or any of the Stockholder's Associates that would have

                                       3.
<PAGE>   4

been permitted to be made pursuant to the first sentence of this Section 3(b) as
a result of such third-party tender offer; (y) any tender offer by the
Stockholder or any of the Stockholder's Associates (as originally made or as
extended or modified) that was permitted to be made pursuant to this Section
3(b) shall have terminated (without closing); or (z) if the provisions of
Section 3(a) shall have terminated as a result of any action by the board of
directors of the Company referred to in clause (ii) of this Section 3(b), the
board of directors of the Company shall have determined not to take any of such
actions (and no such transaction considered by the board of directors of the
Company shall have closed) prior to the commencement of a tender offer by the
Stockholder or any of the Stockholder's Associates that would have been
permitted to be made pursuant to this Section 3(b) as a result of the initial
determination of the board of directors of the Company referred to in clause
(ii) of this Section 3(b), unless prior to such determination by the board of
directors of the Company not to take any such actions, any event referred to in
clause (i) of this Section 3(b) shall have occurred. Upon reinstatement of the
provisions of Section 3(a), the provisions of this Section 3(b) shall continue
to govern in the event that any of the events described in clauses (i) and (ii)
of this Section 3(b) shall occur. Upon the closing of any tender offer for or
acquisition of any securities of the Company or rights or options to acquire any
such securities by the Stockholder or any of the Stockholder's Associates that
would have been prohibited by the provisions of Section 3(a) but for the
provisions of this Section 3(b), all provisions of Section 3(a) and 3(b) shall
terminate.

               (c) As used in this Section 3, "Acquisition Transaction" shall
mean any transaction not contemplated by this Agreement involving:

constituting more than 50% of the consolidated assets of the Company or
accounting for more than 50% of the consolidated revenues of the Company in any
one transaction or in a series of related transactions;

                      (ii) any offer to purchase, tender offer, exchange offer
or any similar transaction or series of related transactions made by any Person
involving more than 50% of the outstanding shares of capital stock of the
Company; or

                      (iii) any merger, consolidation, business combination,
share exchange, reorganization or similar transaction or series of related
transactions involving the Company or any subsidiary of the Company whereby the
holders of voting capital stock of the Company immediately prior to any such
transaction hold less than 50% of the voting capital stock of the Company or the

In consideration for the Rent and other covenants and agreements made by Tenant,

ARTICLE 3: TERM, DELIVERY, AND ACCEPTANCE OF PREMISES

3.1  Delivery of Possession.  Landlord will deliver sole possession of the
Premises to Tenant on the Commencement Date.  Landlord shall deliver to Tenant
possession of the Premises "AS IS" in its present condition on the Commencement
Date.  Tenant acknowledges that neither Landlord nor its agents or employees
have made any representations or warranties as to the suitability or fitness of
the Premises for the conduct of Tenant's business or for any other purpose, nor
has Landlord or its agents or employees agreed to undertake any alterations or
construct any Tenant improvements to the Premises except as may be expressly
provided in this Lease.  If for any reason Landlord cannot deliver possession of
the Premises to Tenant on the Commencement Date, this Lease will not be void or
voidable, and Landlord will not be liable to Tenant for any resultant loss or
damage, but Landlord shall in that case have a period of time not to exceed 45
days in which to deliver possession, during which time the Rent shall be
proportionally abated on a per diem basis, failing which the Lease shall

or other commercial lenders making loans to national borrowers in the
marketplace, within 5 business days of Landlord's request.

3.2  Early Entry.  Upon Landlord's reasonable determination that the Premises or
any portions thereof are otherwise not needed by Landlord and are ready for
Tenant to commence its work therein, Tenant shall be permitted entry to the
Premises prior to the Commencement Date for the purpose of installing fixtures
or any other purpose permitted
<PAGE>

by Landlord, the early entry will be at Tenant's sole risk and subject to all
the terms and provisions of this Lease as though the Commencement Date had
occurred, except for the payment of Rent, which will commence on the dates set
forth above. Tenant, its agents, or employees will not interfere with or delay
Landlord's completion of construction of the improvements. Tenant hereby agrees
to indemnify Landlord against any injury, and loss or damage which may occur to
any person or to any of the Tenant's work or installations made in such
Premises, Building or Project, or to any personal property placed therein, the
same being at Tenant's sole risk, and, prior to any early entry by Tenant,
provide Landlord with proof of insurance coverages described in this Lease.
Landlord has the right to impose additional conditions on Tenant's early entry
that Landlord, in its reasonable discretion, deems appropriate and Landlord will
further have the right to require that Tenant execute an early entry agreement
containing those conditions prior to Tenant's early entry.

ARTICLE 4: MONTHLY RENT

4.1  Throughout the Term of this Lease, Tenant will pay Monthly Rent to Landlord
as rent for the Premises.  Monthly Rent will be paid in advance on or before the
first day of each calendar month of the Term.  If the Term commences on a day
other than the first day of a calendar month or ends on a day other than the
last day of a calendar month, then Monthly Rent will be appropriately prorated
by Landlord based on the actual number of calendar days in such month.  If the
Term commences on a day other than the first day of a calendar month, then the
prorated Monthly Rent for such month will be paid on or before the first day of
the Term.  Monthly Rent will be paid to Landlord, without written notice or
demand, and without deduction or offset, in lawful money of the United States of
America at Landlord's address, or to such other address as Landlord may from
time to time designate in writing.

4.2  Prior to the second anniversary of the Lease, Tenant shall have the
option of selecting a method of calculating rent for the 11th through 15th years
of the Lease. Tenant shall exercise such option by written notice to Landlord of
Tenant's election to calculate rent in accordance with either sub-paragraphs (a)
or (b) below;

(a) 130% of $4,200,000 ($5,460,000); or

(b) the lesser of 140% of $4,200,00 ($5,880,000) or an adjusted annual rent
which is reflective of the increase in the Consumer Price Index ("CPI") and
computed in the following manner:

(i) The applicable CPI shall be the Consumer Price Index for Urban Wage
Earners and Clerical Workers, New York, N.Y. - Northeastern, New Jersey. The
adjusted rent shall be equal to a fraction, the denominator of which shall be
the CPI for March, 2000 (which is the month immediately proceeding the rent
commencement date of the Lease) (the "Base Index"), and the numerator which
shall be the CPI published for March, 2010, (which is the month immediately
proceeding the commencement of the 11th year of the Lease) (the "Adjustment
Index"), multiplied by $4,200,000, as in the following
<PAGE>

examples:

(A) Example 1:  if the Base Index is 100 and the Adjustment Index is 135, the
annual minimum rent for each of the 11th through 15th years of the Lease shall
be equal to 135% of $4,200,000 ($5,670,000).

(B) Example 2:  if the Base Index is 100 and the Adjustment Index is 145, the
annual minimum rent for each of the 11th through 15th years of the Lease shall
be equal to 145% of $4,200,000 ($6,090,000); however this adjusted rent exceeds
$5,880,000 which is 140% of $4,200,000 and therefore the annual minimum rent for
each of the 11th through 15th years of the Lease shall be equal to $5,880,000.

In the event Tenant fails to exercise its option of an election, as set forth
above, prior to the second anniversary of the Lease, rent will be calculated in
accordance with subparagraph (a) above.

4.3 During the ninth year of the Lease, Tenant shall have the option of
selecting a method of calculating rent for the 16th through 20th years of the
Lease. Tenant shall exercise such option by written notice to Landlord of
Tenant's election to calculate rent in accordance with either sub-paragraphs (a)
or (b) below:

(a) 115% of the rent in effect during the 15th year of the Lease; or

(b) the lesser of 120% of the rent in effect during the 15th year of the Lease
or an adjusted annual rent which is reflective of the increase in the Consumer
Price Index ("CPI") and computed in the following manner:

     (i) The applicable CPI shall be the Consumer Price Index for Urban Wage
Earners and Clerical Workers, New York, N.Y. - Northeastern, New Jersey.  The
adjusted rent shall be equal to a fraction, the denominator of which shall be
the CPI for March, 2010 (which is the month immediately proceeding the 11th year
of the Lease) (the "Base Index"), and the numerator of which shall be the CPI
published for March, 2015, (which is the month immediately proceeding the
commencement of the 16th year of the Lease) (the "Adjustment Index"), multiplied
by the rent in effect during the 15th year of the Lease.

In the event Tenant fails to exercise its option of election, as set forth
above, during the ninth year of the Lease, rent will be calculated in accordance
with sub-paragraph (a) above.

ARTICLE 5: NET LEASE

5.1  NET LEASE

The payments of rent shall be absolutely net to Landlord.  Tenant shall be
responsible for
<PAGE>

all costs of operating the premises, including, but not limited to taxes,
insurances, utilities, cleaning, repairs, including all structural repairs, roof

own costs and expense.

5.3  STRUCTURAL REPAIRS

or make major structural repairs, Tenant shall pay for the cost of such work,

Such partial reimbursement shall be calculated by apportioning the remaining
useful life of such repair or replacement between Landlord and Tenant.  For
purpose of this calculation, useful life shall not exceed seven years.

Landlord will appoint Westminster Management to manage the premises at Tenant's
cost in accordance with a separate management agreement.  Managing agent may be

other amounts as Landlord may from time to time reasonably request, with
insurance companies and on forms satisfactory to Landlord:

(a)  Bodily injury and property damage liability insurance, with a combined

and completed operations, broad form property damage, and contractual liability
coverage for the performance by Tenant;

(b) Insurance covering all of Tenant's furniture and fixtures, machinery,
equipment, stock, and any other personal property owned and used in Tenant's
business and found in, on, or about the Project, and any leasehold improvements

forms will provide coverage on a broad form basis insuring against "all risks of
direct physical loss." All policy proceeds will be used for the repair or
replacement of the property damaged or destroyed; however, if this Lease ceases
under the provisions of Article 15, Tenant will be entitled to any proceeds
resulting from damage to Tenant's furniture and fixtures, machinery, equipment,
stock, and any other personal property;

(c)  Worker's compensation insurance insuring against and satisfying Tenant's
obligations and liabilities under the workers' compensation laws of the state in
which the Project is located, including employers' liability insurance in the

to effect such insurance at the sole cost of the Tenant and all outlays by
Landlord shall be reimbursed by Tenant to Landlord as Additional Rent unless
Tenant shall have obtained or reinstated such insurance after 5 days notice from
Landlord..

6.3  Forms of Policies.  Certificates of insurance, together with copies of the
endorsements, when applicable, naming Landlord and any others specified by
Landlord as additional insureds, will be delivered to Landlord prior to Tenant's
occupancy of the Premises and from time to time at least 10 days prior to the
expiration of the term of each such policy.  All commercial general liability or
comparable policies maintained by Tenant will name Landlord and such other
persons or firms as Landlord specifies from time to time as additional insureds,
entitling them to recover under such policies for any loss sustained by them,
their agents, and employees, including those losses sustained as a result of the
negligent acts or omissions of Tenant.  All such policies maintained by Tenant
will provide that they may not be terminated nor may coverage be reduced except
after 30 days' prior written notice to Landlord.  All commercial general
liability, automobile, and property policies maintained by Tenant will be
written as primary
<PAGE>

policies, not contributing with and not supplemental to the coverage that
Landlord may carry.

6.4  Waiver of Subrogation.  Landlord and Tenant each waive any and all rights
to recover against the other or against any other tenant or occupant of the
Project, or against the officers, directors, shareholders, partners, joint
venturers, employees, agents, customers, invitees, or business visitors of such
other party or of such other tenant or occupant of the Project, for any loss or
damage to such waiving party arising from any cause covered by any property
insurance required to be carried by such party pursuant to this Article 6 or any
other property insurance actually carried by such party to the extent of the
limits of such policy.  Landlord and Tenant from time to time will cause their
respective insurers to issue appropriate waiver of subrogation rights
endorsements to all property insurance policies carried in connection with the
Project or the Premises or the contents of the Project or the Premises.  Tenant
agrees to cause all other occupants of the Premises claiming by, under, or
through Tenant to execute and deliver to Landlord such a waiver of claims and to
obtain such waiver of subrogation rights endorsements.

6.5  Adequacy of Coverage.  Landlord, its agents and employees make no
representation that the limits of liability specified to be carried by Tenant
pursuant to this Article 6 are adequate to protect Tenant.  If Tenant believes
that any of such insurance coverage is inadequate, Tenant shall obtain such
additional insurance coverage as Tenant deems adequate, at Tenant's sole
expense.

ARTICLE 7: USE

Tenant covenants that the Premises will be used only for general business office
purposes including a technology and communications company and purposes
incidental to that use, or such other uses as permitted by the applicable zoning
ordinances and for no other purpose.  Tenant will use the Premises in a careful,
safe, and proper manner.  Tenant will not use or permit the Premises to be used

disposition of any hazardous materials in, on, or about the Premises or the
Project by Tenant, its agents, employees, or contractors, nor shall Tenant

violation of any hazardous materials laws. Tenant will immediately advise
Landlord in writing of (1) any and all enforcement, cleanup, remedial, removal,
or other governmental or regulatory actions instituted, completed, or threatened
pursuant to any hazardous materials laws relating to any hazardous materials
affecting the Premises; and (2) all claims made or threatened by any third party
against Tenant, Landlord, the Premises or the Project relating to damage,
contribution, cost recovery, compensation, loss, or injury resulting from any
hazardous materials on or about the Premises. Without Landlord's prior written
consent, Tenant will not take any remedial action or enter into any agreements
or settlements in response to the presence of any hazardous materials in, on, or
about the Premises.

(c)  Tenant will be solely responsible for and will defend, indemnify and hold
Landlord, its agents, and employees harmless from and against all claims, costs,

out of or in connection with Tenant's breach of its obligations in this Article

or thing upon the Premises or the Project which would (a) jeopardize or be in

such act or omission to continue, Tenant shall pay any increase in premium as
Additional Rent.

property, and trade fixtures located in the Premises) in their condition at the
time they were delivered to Tenant, reasonable wear and tear excluded.  Tenant

ARTICLE 11.1: ALTERATIONS

11. 1 General.

(a)  Tenant will not make or allow to be made any alterations, additions, or
improvements of a mechanical or structural nature to or of the Premises or any
part of the Premises cost of which exceeds $150,000, or attach any fixtures or
equipment to the Premises, without first obtaining Landlord's written consent
which consent shall not be
<PAGE>

unreasonably withheld. In no event shall the work of Tenant affect or impair the
structure, the elevators, or utility systems of the Building. Landlord's
approval of the plans, specifications, and working drawings for such alterations
shall create no responsibility or liability on the part of the Landlord for
their completeness, design sufficiency, or compliance with all laws, ordinances,
rules, requirements, and regulations of governmental agencies or authorities, or
the use and occupancy permit for the Building. All such alterations, additions,
and improvements consented to by Landlord, and capital improvements that are
required to be made to the Project as a result of the nature of Tenant's use of
the Premises:

(1)  Will be performed by reputable, qualified, experienced contractors subject
to conditions specified by Landlord (which may include requiring the posting of
performance and payment bonds); and further subject to Landlord's reasonable
approval;

(2)  Will be done in a good and workmanlike manner and shall be completed
promptly;

(3)  Will be performed according to plans, specifications, and working drawings
approved by Landlord if required; and

(4)  Will be in accordance with all applicable federal, state, county and local
laws, rules, regulations, ordinances and codes.

At all times between the start and completion of the work, in addition to the
other policies of insurance required by this Lease, Tenant shall maintain a
policy of "All Risk" Builder's Risk Insurance covering the full replacement
value of all work done and fixtures and equipment installed or to be installed
at the Premises pursuant to this Article 11.  Tenant herewith agrees to be
responsible for all damages to persons or property, including loss of life, as a
result of occurrences connected with activities undertaken by Tenant, its
agents, contractors, and employees pursuant hereto, and hereby indemnifies
Landlord and shall defend and hold Landlord harmless from and against any and
all loss, cost or expense in connection with its responsibilities hereunder.

(5)  Subject to Tenant's rights in Article 11.2, all alterations, additions,
fixtures, and improvements, whether temporary or permanent in character, made in
or upon the Premises either by Tenant or Landlord, will become Landlord's
property at the end of the Term and at the end of the Term will remain on the
Premises without compensation to Tenant except as provided in 11.3.

11.2  Free-Standing Partitions and Non Structural Alterations Additions and
Improvements.  Tenant will have the right to install free-standing work station
partitions and make non structural alterations additions and improvements,
without Landlord's prior written consent, so long as no building or other
governmental permit is required for their installation or relocation; however,
if a permit is required, Landlord will not unreasonably withhold its consent to
such relocation or installation.  The free-standing work station partitions for
which Tenant pays will be part of Tenant's trade fixtures for all purposes
<PAGE>

under this Lease. All other partitions installed in the Premises are and will be
Landlord's property for all purposes under this Lease.

Removal.  If Landlord has requested Tenant to remove any or all alterations,
additions, fixtures, and improvements that are made in or upon the Premises
pursuant to this Article 11 at the end of the Term during the first 30 years of
this Lease, Tenant will remove such alterations, addition fixtures and
improvements at Tenant's sole cost and will restore the Premises to the
condition in which they were before such alterations, additions, fixtures,
improvements, and additions were made.

ARTICLE 12: MECHANICS LIENS

Tenant will pay or cause to be paid all costs and charges for work (a) done by
Tenant or caused to be done by Tenant, in or to the Premises, and (b) for all
materials furnished for or in connection with such work. Tenant will indemnify
Landlord against and defend and hold Landlord, the Premises, and the Project
free, clear, and harmless of and from all mechanics' liens and claims of liens,
and all other liabilities, liens, claims, and demands on account of such work by
or on behalf of Tenant.  If any such lien, at any time, is filed against the
Premises or any part of the Project, Tenant will cause such lien to be
discharged of record within 10 days after the filing of such lien, except that
if Tenant desires to contest such lien, it will furnish Landlord, within such
10-day period, security reasonably satisfactory to Landlord of at least 150% of
the amount of the claim, plus estimated costs and interest, or comply with such
statutory procedures as may be available to release the lien.  If a final
judgment establishing the validity or existence of a lien for any amount is
entered, Tenant will pay and satisfy the same at once.  If Tenant fails to pay
any charge for which a mechanics' lien has been filed, and has not given
Landlord security as described above, or has not complied with such statutory
procedures as may be available to release the hen, Landlord may, at its option,
pay such charge and related costs and interest, and the amount so paid, together
with reasonable attorneys' fees incurred in connection with such lien, will be
immediately due from Tenant to Landlord as Additional Rent.  Nothing contained
in this Lease will be deemed the consent or agreement of Landlord to subject
Landlord's interest in the Project to liability under any mechanics' or other
lien law.  If Tenant receives written notice that a lien has been or is about to
be filed against the Premises or the Project, or that any action affecting title
to the Project has been commenced on account of work done by or for or materials
furnished to or for Tenant, it will immediately give Landlord written notice of
such notice.  At least 15 days prior to the commencement of any work included in
Article 11 in or to the Premises, by or for Tenant, Tenant will give Landlord
written notice of the proposed work and the names and addresses of the persons
supplying labor and materials for the proposed work.  Landlord will have the
right to post notices of nonresponsibility or similar written notices on the
Premises in order to protect the Premises against any such liens.

ARTICLE 13: END OF TERM
<PAGE>

At the end of this Lease, Tenant will promptly quit and surrender the Premises
broom-clean, in good order and repair, ordinary wear and tear excepted and
deliver all keys to the Premises and the Building  to Landlord.  If Tenant is
not then in default, Tenant may remove from the Premises any trade fixtures,
equipment and movable furniture placed in the Premises by Tenant, whether or not
such trade fixtures or equipment are fastened to the Building.  Whether or not
Tenant is in default, Tenant will remove such alterations, additions,
improvements, trade fixtures, equipment, and furniture as Landlord has requested
in accordance with Article 11.  Tenant will fully repair any damage occasioned
by the removal of any trade fixtures, equipment, furniture, alterations,
additions, and improvements.  All trade fixtures, equipment, furniture,
inventory, effects, alterations, additions, and improvements on the Premises
after the end of the Term will be deemed conclusively to have been abandoned and
may be appropriated, sold, stored, destroyed, or otherwise disposed of by
Landlord without notice to Tenant or any other person and without obligation to
account for them. Tenant will pay Landlord for all expenses incurred in
connection with the removal of such property, including but not limited to the
cost of storage, and the cost of repairing any damage to the Building or
Premises caused by the removal of such property.  Tenant's obligation to observe
and perform this covenant will survive the expiration or other termination of
this Lease.

ARTICLE 14: EMINENT DOMAIN

If all of the Premises are taken by exercise of the power of eminent domain (or
conveyed by Landlord in lieu of such exercise) this Lease will terminate on a
date (the "termination date") which is the earlier of the date upon which the
condemning authority takes possession of the Premises or the date on which title
to the Premises is vested in the condemning authority.  If more than 25% of the
Rentable Area of the Premises is so taken, Tenant will have the right to cancel
this Lease by written notice to Landlord given within 20 days after the
termination date.  If less than 25% of the Rentable Area of the Premises is so
taken, or if the Tenant does not cancel this Lease according to the preceding
sentence, the Rent will be abated in the proportion of the Rentable Area of the
Premises so taken to the Rentable Area of the Premises immediately before such
taking, and Tenant's Share will be appropriately recalculated.  If 25% or more
of the Building is so taken, Landlord may cancel this Lease by written notice to
Tenant given within 30 days after the termination date.  In the event of any
such taking, the entire award will be paid to Landlord, and Tenant will have no
right or claim to any part of such award; however, Tenant will have the right to
assert a claim against the condemning authority in a separate action, so long as
Landlord's award is not reduced as a consequence of such claim for Tenant's
moving expenses and trade fixtures owned by Tenant.

ARTICLE 15: DAMAGE AND DESTRUCTION

(a)  If the Premises or the Building is damaged by fire or other insured
casualty, Landlord will give Tenant written notice of the time which will be
needed to repair such
<PAGE>

damage, as determined by Landlord in its reasonable discretion, and the election
(if any) which Landlord has made according to this Article 15. Such notice will
be given before the 60th day (the "notice date") after the fire or other insured
casualty.

(b)  If the Premises or the Building is damaged by fire or other insured
casualty to an extent which may be repaired within 270 days after the notice
date, as reasonably determined by Landlord, Landlord will promptly begin to
repair the damage after the notice date and will diligently pursue the
completion of such repair. In that event this Lease will continue in full force
and effect except that Rent will be abated on a pro rata basis from the date of
the damage until the date of the completion of such repairs (the "repair
period") based on the proportion of the Rentable Area of the Premises Tenant is
unable to use during the repair period.

(c)  If the Premises or the Building is damaged by fire or other insured
casualty to an extent that may not be repaired within 270 days after the notice
date, as reasonably determined by Landlord, then (1) Landlord may cancel this
Lease as of the date of such damage by written notice given to Tenant on or
before the notice date or (2) Tenant may cancel this Lease as of the date of
such damage by written notice given to Landlord within 10 days after Landlord's
delivery of a written notice that the repairs cannot be made within such 270-day
period. If neither Landlord nor Tenant so elects to cancel this Lease, Landlord
will diligently proceed to repair the Building and Premises and Rent will be
abated on a pro rata basis during the repair period based on the proportion of
the Rentable Area of the Premises Tenant is unable to use during the repair
period.

(d)  Notwithstanding the provisions of subparagraphs (a), (b), and (c) above, if
the Premises or the Building or the Project are damaged by uninsured casualty,
or if the proceeds of insurance are insufficient to pay for the repair of any
damage to the Premises or the Building or the Project, Landlord will have the
option to repair such damage or cancel this Lease as of the date of such
casualty by written notice to Tenant on or before the notice date.

(e)  If any such damage by fire or other casualty is the result of the willful
conduct of Tenant, its agents, employees, there will be no abatement of Monthly
Rent as otherwise provided for in this Article 15 if Landlord does not have
adequate insurance proceeds available to compensate it for the loss of rent and
all necessary repairs and restorations. Tenant will have no rights to terminate
this Lease on account of any damage to the Premises, the Building, or the
Project, except as set forth in this Lease.

(f)  For purposes of this Article 15 and subject to subsections (a) through (e)
hereof, Landlord shall repair or restore any portion of the alterations,
additions or improvements in the Premises or the decorations thereto to the
extent that such alterations, additions, improvements and decorations were
provided by Landlord at the beginning of the Term. Landlord shall have no
additional obligations pursuant to this Lease to repair or restore any
alterations, additions or improvements in the Premises or the decorations
thereto. If Tenant desires any other or additional repairs or restoration and if
Landlord consents thereto, the same shall be done at Tenant's sole cost and
expense. Tenant acknowledges
<PAGE>

that Landlord shall be entitled to the full proceeds of any insurance coverage,
carried by Landlord for damage to alterations, additions, improvements or
decorations.

ARTICLE 16: SUBORDINATION

16.l   General. This Lease and Tenant's rights under this Lease are subject and
subordinate to any ground or underlying lease, mortgage, indenture, deed of
trust, or other lien encumbrance (each a "superior lien"), together with any
renewals, extensions, modifications, consolidations, and replacements of such
superior lien, now or in the future affecting or placed, charged, or enforced
against the Land, the Building, or all or any portion of the Project or any
interest of Landlord in them or Landlord's interest in this Lease and the
leasehold estate created by this Lease (except to the extent any such instrument
expressly provides that this Lease is superior to such instrument).  This
provision will be self-operative and no further instrument of subordination will
be required in order to effect it.  Notwithstanding the foregoing, Tenant will
execute, acknowledge, and deliver to Landlord, within 20 days after written
demand by Landlord, such documents as may be reasonably requested by Landlord or
the holder of any superior lien to confirm or effect any such subordination or
superiority, as applicable.

16.2  Attornment. Tenant agrees that in the event that any holder of a superior
lien succeeds to Landlord's interest in the Premises, Tenant will pay to such
holder all Rent subsequently payable under this Lease.  Further, Tenant agrees
that in the event of the enforcement by the holder of a superior lien of the
remedies provided for by law or by such superior lien, Tenant will, upon request
of any person or party succeeding to the interest of Landlord as a result of
such enforcement, automatically become the Tenant of and attorn to such
successor in interest without change in the terms or provisions of this Lease.
Such successor in interest will not be bound by:

(a)  Any payment of Rent for more than one month in advance, except prepayments
in the nature of security for the performance by Tenant of its obligations under
this Lease that are actually received by such successor in interest;

(b)  Any claim against Landlord arising prior to the date on which such
successor in interest succeeded to Landlord's interest; or

(c)  Any claim or offset of Rent against the Landlord.

Upon request by such successor in interest and without cost to Landlord or such
successor in interest, Tenant will, within 20 days after written demand,
execute, acknowledge, and deliver an instrument or instruments confirming the
attornment.

If Tenant shall fail to execute and deliver any such documents provided for in
the preceding sentence, then Tenant hereby appoints Landlord its attorney-in-
fact for the purpose of executing, acknowledging, and delivering such documents
on behalf of Tenant.
<PAGE>

Landlord shall procure an agreement upon request of Tenant from the party to
which Tenant is to subordinate and/or attorn, which agreement shall be a
nondisturbance agreement on standard forms and with standard terms then
generally used by commercial lenders in the United States.  The aforesaid
subordination shall be uneffective if a nondisturbance agreement is unable to be
procured in accordance herewith.

ARTICLE 17: ENTRY BY LANDLORD

Landlord, its agents, employees, and contractors may enter the Premises at any
time in response to an emergency and at any other reasonable time upon 48 hours
prior notice to:

(a)  Inspect the Premises; or show premises to prospective lenders or
purchasers;

(b)  Determine whether Tenant is complying with all its obligations in this
Lease;

(c)  During the last 15 months of the lease term, exhibit the premises to
prospective purchasers, or tenants.

Tenant, by this Article, waives any claim against Landlord, its agents,
employees, or contractors for damages for any injury or inconvenience to or
interference with Tenant's business, any loss of occupancy or quiet enjoyment of
the Premises, or any other loss occasioned by any entry in accordance with this
Article 17.  Landlord will at all times have and retain a key with which to
unlock all of the doors in, on, or about the Premises (excluding Tenant's
vaults, safes, and similar areas designated in writing by Tenant in advance).
Landlord will have the right to use any and all means Landlord may deem proper
to open doors in and to the Premises in an emergency in order to obtain entry to
the Premises, provided that Landlord will promptly repair any damages caused by
any forced entry.  Any entry to the Premises by Landlord in accordance with this
Article 17 will not be construed or deemed to be a forcible or unlawful entry
into or a detainer of the Premises or an eviction, actual or constructive, of
Tenant from the Premises or any portion of the Premises, nor will any such entry
entitle Tenant to damages or an abatement of Monthly Rent, Additional Rent, or
other charges that this Lease requires Tenant to pay.  Except in the case of an
emergency, Tenant shall have the right to accompany Landlord upon any entry
pursuant to this Article, and Tenant shall have the right to designate areas in
the Premises that are sensitive and not subject to entry by Landlord except in a
true emergency.

ARTICLE 18: INDEMNIFICATION, WAIVER AND RELEASE

18.1  Indemnification.  To the extent not prohibited by law, Landlord, its
employees and agents shall not be liable for damage to person, property, or
business or resulting from the loss of use thereof sustained by Tenant or other
persons due to the buildings or any part thereof becoming out of repair or due
to an accident or any act or neglect of any
<PAGE>

tenant, occupant or other person. Tenant further agrees that all personal
property upon the premises, loading dock, holding area, and freight elevators,
shall be at the sole risk of Tenant. Tenant will neither hold nor attempt to
hold Landlord , its employees, or agents liable for, and Tenant will indemnify
and defend and hold harmless Landlord, its employees, and agents from and
against, any and all demands, claims, causes of action, fines, penalties,
damages (including consequential damages), liabilities, judgments, and expenses
(including without limitation reasonable attorneys' fees incurred in connection
with or arising from:

(a)  the use or occupancy or manner of use or occupancy of the premises or any
common areas by Tenant or any person claiming under Tenant

(b)  any activity, work, or thing done or permitted by Tenant in or about the
Premises, the building, or the project;

(c)  any breach by Tenant or its employees, agents, contractors, or invitees of
this Lease; and

(d)  any injury or damage to the person, property, or business of the Tenant,
its employees, agents, contractors, or invitees entering upon the premises under
the expressed or implied invitation of Tenant.

If any action or proceeding is brought against Landlord, its employees, or
agents by reason of any such claim for which Tenant has indemnified Landlord,
Tenant, upon written notice from Landlord, will defend the same at Tenant's
expense with counsel reasonably satisfactory to Landlord.

18.2  Landlord agrees to indemnify and hold harmless Tenant from and against all
claims, suits, expenses, damages, and costs of any and all suits including
attorneys fees and cost of suit resulting from or arising out of Landlord's
gross negligence or willful misconduct.

18.3  Waiver and Release.  Tenant, as a material part of the consideration to
Landlord for this Lease, by this Article 18 waives and releases all claims
against Landlord, its employees, and agents with respect to all matters for
which Landlord has disclaimed liability pursuant to the provisions of this
Lease.

ARTICLE 19: SECURITY DEPOSIT

Tenant shall deposit the security deposit with Landlord as security for the
full, faithful, and timely performance of every provision of this Lease to be
performed by Tenant within seven days from the execution hereof.  If Tenant
defaults with respect to any provision of this Lease, including but not limited
to the provisions relating to the payment of Rent, Landlord may use, apply, or
retain all or any part of the security deposit for the payment of any Rent, or
any other sum in default, or for the payment of any other amount
<PAGE>

Landlord may spend or become obligated to spend by reason of Tenant's default,
or to compensate Landlord for any other loss or damage Landlord may suffer by
reason of Tenant's default. If any portion of the security deposit is so used,
applied, or retained, Tenant will within 5 days after written demand deposit
cash with Landlord in an amount sufficient to restore the security deposit to
its original amount. Landlord will not be required to keep the security deposit
separate from its general funds, and Tenant will not be entitled to interest on
the security deposit. The security deposit will not be deemed a limitation on
Landlord's damages or a payment of liquidated damages or a payment of the
Monthly Rent due for the last month of the Term. If Tenant fully, faithfully,
and timely performs every provision of this Lease to be performed by it, the
security deposit or any balance of the security deposit will be returned to
Tenant within 45 days after the expiration of the Term. Landlord shall notify
Tenant that it intends to, and may then deliver the balance of the security
deposit then held by Landlord to the purchaser of the Building in the event the
Building is sold or to any transferee or assignee from Landlord, and after such
time Landlord will have no further liability to Tenant with respect to the
security deposit. The security deposit may be posted in the form of a letter of
credit which must be assignable, clean, irrevocable, evergreen, sight draft, in
all respects acceptable to Landlord in its discretion, and any failure to
maintain such letter of credit in force shall be an immediate material default
hereunder, which if not cured by an identical substitute letter of credit or
cash deposit equal to the Security Deposit with Landlord, shall entitle Landlord
to all remedies available to it for breach of this Lease.

ARTICLE 20: QUIET ENJOYMENT

Landlord covenants and agrees with Tenant that so long as Tenant pays the Rent
and observes and performs all the terms, covenants, and conditions of this Lease
on Tenant's part to be observed and performed, Tenant may peaceably and quietly
enjoy the Premises subject, nevertheless, to the terms and conditions of this
Lease, and Tenant's possession will not be disturbed by anyone claiming by,
through, or under Landlord.

ARTICLE 21: EFFECT OF SALE

A sale, conveyance, or assignment of the Building or the Project will operate to
release Landlord from liability from and after the effective date of such sale,
conveyance, or assignment upon all of the covenants, terms, and conditions of
this Lease, express or implied, except those liabilities that arose prior to
such effective date, and, after the effective date of such sale, conveyance, or
assignment, Tenant will look solely to Landlord's successor in interest in and
to this Lease.  This Lease will not be affected by any such sale, conveyance, or
assignment, and Tenant will attorn to Landlord's successor in interest to this
Lease from and after such effective date.

ARTICLE 22: DEFAULT
<PAGE>

22.1  Events of Default.  The following events are referred to, collectively, as
"events of default" or, individually, as an "event of default":

(a)  Tenant fails to pay any Rent or other monetary obligation within 5 days of
the date when due;

(b)  Tenant abandons the Premises;

(c)  This Lease or the Premises or any part of the Premises is taken upon
execution or by other process of law directed against Tenant, or is taken upon
or subject to any attachment by any creditor of Tenant or claimant against
Tenant, and said attachment is not discharged or disposed of within 15 days
after its levy;

(d)  Tenant or any guarantor of Tenant's obligations under this Lease
("Guarantor") files a petition in bankruptcy or insolvency or for reorganization
or arrangement under the bankruptcy laws of the United States or under any
insolvency act of any state, or admits the material allegations of any such
petition by answer or otherwise, or admits in writing its inability to meet its
debts as they mature, or is dissolved or makes an assignment for the benefit of
creditors;

(e)  Involuntary proceedings under any such bankruptcy law or insolvency act or
for the dissolution of Tenant or any Guarantor are instituted against Tenant or
any Guarantor, or a receiver or trustee is appointed for all or substantially
all of the property of Tenant or any Guarantor, and such proceeding is not
dismissed or such receivership or trusteeship vacated within 60 days after such
institution or appointment;

(f)  Tenant breaches any of the agreements, terms, covenants, or conditions of
this Lease and such breach involves a hazardous condition and is not cured
promptly upon written notice to Tenant;

(g)  Tenant breaches any of the other agreements, terms, covenants, or
conditions that this Lease requires Tenant to perform, and such breach continues
for a period of 30 days after written notice from Landlord to Tenant or, if such
breach cannot be cured reasonably within such 30-day period, if Tenant fails to
diligently commence to cure such breach within 30 days after written notice from
Landlord and to complete such cure within a reasonable time thereafter; or

(h)  A letter of credit posted as a Security Deposit is allowed to expire
without a replacement or the Security Deposit is not maintained at an amount
equal to two years' rent.

In no event shall Landlord's acceptance of a check or other form of payment
which is not in the amount required to be paid to Landlord under the terms of
this Lease constitute a waiver of Landlord's rights to insist on strict and full
payment as set forth in this Lease.

22.2  Landlord's Remedies.  If any one or more events of default set forth in
Article
<PAGE>

22.1 occurs then Landlord has the right, at its election:

(a)  To give Tenant written notice of Landlord's intention to terminate this
Lease on the earliest date permitted by law or on any later date specified in
such notice, in which case Tenant's right to possession of the Premises will
cease and this Lease will be terminated, except as to Tenant's liability, as if
the expiration of the term fixed in such notice were the end of the Term;

(b)  Without further demand or notice, and without terminating this Lease, to
reenter and take possession of the Premises or any part of the Premises,
repossess the same, expel Tenant and those claiming through or under Tenant, and
remove the effects of both or either, using such force for such purposes as may
be necessary, without being liable for prosecution, without being deemed guilty
of any manner of trespass, and without prejudice to any remedies for arrears of
Monthly Rent or other amounts payable under this Lease or as a result of any
preceding breach of covenants or conditions; or

(c)  Without further demand or notice to cure any event of default and to charge
Tenant for the cost of effecting such cure, including without limitation
reasonable attorneys' fees and interest on the amount so advanced at the rate
set forth in Article 24.20, provided that Landlord will have no obligation to
cure any such event of default of Tenant.

Should Landlord elect to reenter as provided in subsection (b), or should
Landlord take possession pursuant to legal proceedings or pursuant to any notice
provided by law, Landlord may, from time to time, without terminating this
Lease, relet the Premises or any part of the Premises in Landlord's or Tenant's
name, but for the account of Tenant, for such term or terms (which may be
greater or less than the period which would otherwise have constituted the
balance of the Term) and on such conditions and upon such other terms (which may
include concessions of free rent and alteration and repair of the Premises) as
Landlord, in its reasonable discretion, may determine, and Landlord may collect
and receive the rents from such reletting.  Landlord will in no way be
responsible or liable for any failure to relet the Premises, or any part of the
Premises, or for any failure to collect any rent due upon such reletting.  No
such reentry or taking possession of the Premises by Landlord will be construed
as an election on Landlord's part to terminate this Lease unless a written
notice of such intention is given to Tenant.  No written notice from Landlord
under this Article or under a forcible or unlawful entry and detainer statute or
similar law will constitute an election by Landlord to terminate this Lease
unless such notice specifically so states.  Landlord reserves the right
following any such reentry or reletting to exercise its right to terminate this
Lease by giving Tenant such written notice, in which event this Lease will
terminate as specified in such notice.

22.3  Certain Damages.  In the event that Landlord does not elect to terminate
this Lease as permitted in Article 22.2(a) but on the contrary elects to take
possession as provided in Article 22.2(b), Tenant will pay to Landlord Monthly
Rent and other sums as provided in this Lease that would be payable under this
Lease if such repossession had not occurred, less the net proceeds, if any, of
any reletting of the Premises after deducting
<PAGE>

all of Landlord's reasonable expenses in connection with such reletting,
including without limitation all repossession costs, brokerage commissions,
attorneys' fees, expenses of employees, alteration and repair costs, and
expenses of preparation for such reletting. Tenant will pay such Rent and other
sums to Landlord monthly on the day on which the Monthly Rent would have been
payable under this Lease if possession had not been retaken, and Landlord will
be entitled to receive such Rent and other sums from Tenant on each such day.

22.4  Continuing Liability After Termination.  If this Lease is terminated on
account of the occurrence of an event of default, Tenant will remain liable to
Landlord for damages in an amount equal to the Rent and other amounts that would
have been owing by Tenant for the balance of the Term, had this Lease not been
terminated, less the net proceeds, if any, of any reletting of the Premises by
Landlord subsequent to such termination, after deducting all of Landlord's
expenses in connection with such reletting, including without limitation the
expenses enumerated in Article 22.3. Landlord will be entitled to collect such
damages from Tenant monthly on the day on which Monthly Rent and other amounts
would have been payable under this Lease if this Lease had not been terminated
and Landlord will be entitled to receive such Monthly Rent and other amounts
from Tenant on each such day. Alternatively, at the option of Landlord, in the
event this Lease is so terminated, Landlord will be entitled to recover against
Tenant as damages for loss of the bargain and not as a penalty. Any other amount
necessary to compensate Landlord for all expenses actually incurred by Landlord
directly related to Landlord's mortgage, proximately caused by Tenant.

22.5  Cumulative Remedies.  Any suit or suits for the recovery of the amounts
and damages set forth in Articles 22.3 and 22.4 may be brought by Landlord, from
time to time, at Landlord's election, and nothing in this Lease will be deemed
to require Landlord to await the date upon which this Lease or the Term would
have expired had there occurred no event of default. Each right and remedy
provided for in this Lease is cumulative and is in addition to every other right
or remedy provided for in this Lease or now or after the Lease Date existing at
law or in equity or by statute or otherwise, and the exercise or beginning of
the exercise by Landlord of any one or more of the rights or remedies provided
for in this Lease or now or after the Lease Date existing at law or in equity or
by statute or otherwise will not preclude the simultaneous or later exercise by
Landlord of any or all other rights or remedies provided for in this Lease or
now or after the Lease Date existing at law or in equity or by statute or
otherwise. All costs incurred by Landlord in collecting any amounts and damages
owing by Tenant pursuant to the provisions of this Lease or to enforce any
provision of this Lease, including reasonable attorneys' fees from the date any
such matter is turned over to an attorney, whether or not one or more actions
are commenced by Landlord, will also be recoverable by Landlord from Tenant.

22.6  Waiver of Redemption.  Tenant waives any right of redemption arising as a
result of Landlord's exercise of its remedies under this Article 22.

22.7  Time of Default.  A default shall occur upon the expiration of any
applicable notice and
<PAGE>

cure periods under the terms of this Lease.

22.8  Disputes. When Tenant is in default for nonpayment of any sums due under
this Lease, for such time as Tenant is so in default, Tenant is barred from
disputing any acts of Landlord, any matters under this Lease or protesting any
Landlord acts or omissions.

ARTICLE 23: PARKING

Tenant shall have the right to build an additional level or levels to the
parking deck.  Landlord shall have the right to approve building plans,
construction and contractors prior to commencement of construction which
approval shall not be unreasonably withheld or delayed.  Tenant shall comply
with all applicable governmental regulations relative to the construction
thereof.  Landlord makes no representation as to the ability of Tenant to build
additions to parking area.

ARTICLE 24: MISCELLANEOUS

24.1  No Offer.  Submission of the Lease to Tenant is for examination and shall
not bind Landlord in any manner.  No lease or obligations of Landlord shall
arise until this instrument is signed by both Landlord and Tenant and delivery
is made to each

24.2  Joint and Several Liability.  If Tenant is composed of more than one
signatory to this Lease, each signatory will be jointly and severally liable
with each other signatory for payment and performance according to this Lease.
The act of, written notice to, written notice from, refund to, or signature of
any signatory to this Lease (including without limitation modifications of this
Lease made by fewer than all such signatories) will bind every other signatory
as though every other signatory had so acted, or received or given the written
notice or refund, or signed.

24.3  No Construction Against Drafting Party.  Landlord and Tenant acknowledge
that each of them and their counsel have had an opportunity to review this Lease
and that this Lease will not be construed against Landlord merely because
Landlord has prepared it.

24.4  No Recordation.  Tenant's recordation of this Lease or any memorandum or
short form of it will be void and an event of default under this Lease.
Landlord and Tenant shall execute a memorandum of lease and have it properly
acknowledged for the purpose of recording if required by Tenant's lender.  The
cost of recording such short-form lease shall be borne by Tenant.  Tenant and
Landlord shall execute a discharge of memorandum at the time such memorandum is
executed, which discharge shall be held in escrow by Landlord's counsel to be
recorded when the Tenant vacates the Premises or the Lease goes into default
beyond cure

24.5  No Waiver.  No waiver by Landlord of any agreement, condition or provision
contained in this Lease will be valid or binding unless expressed in writing and
signed by Landlord.  The waiver by Landlord of any agreement, condition, or
provision contained
<PAGE>

in this Lease will not be deemed to be a waiver of any subsequent breach of the
same or any other agreement, condition, or provision contained in this Lease,
nor will any custom or practice that may grow up between the parties in the
administration of the terms of this Lease be construed to waive or to lessen the
right of Landlord to insist upon the performance by Tenant in strict accordance
with the terms of this Lease. The subsequent acceptance of Rent by Landlord will
not be deemed to be a waiver of any preceding breach by Tenant of any agreement,
condition, or provision of this Lease, other than the failure of Tenant to pay
the particular Rent so accepted, regardless of Landlord's knowledge of such
preceding breach at the time of acceptance of such Rent.

24.6  Limitation on Recourse.  Tenant specifically agrees to look solely to
Landlord's interest in the Project for the recovery of any judgments from
Landlord.  It is agreed that Landlord (and its agents, shareholders, venturers,
and partners, and their shareholders, venturers, and partners and all of their
officers, directors, and employees) will not be personally liable for any such
judgments.

24.7  Estoppel Certificates.  At any time and from time to time but within 5
business days after prior written request by Landlord, Tenant will execute,
acknowledge, and deliver to Landlord or such other person as Landlord shall
direct, promptly upon request, a certificate certifying (a) that this Lease is
unmodified and in full force and effect or, if there have been modifications,
that this Lease is in full force and effect, as modified, and stating the date
and nature of each modification; (b) the date, if any, to which Rent and other
sums payable under this Lease have been paid; (c) that no written notice of any
default has been delivered to Landlord which default has not been cured, except
as to defaults specified in said certificate; (d) that the Tenant has no
knowledge of and that there is no event of default under this Lease or an event
which, with notice or the passage of time, or both, would result in an event of
default under this Lease, except for defaults specified in said certificate; and
(e) such other matters as may be reasonably requested by Landlord.  Any such
certificate may be relied upon by any prospective purchaser or existing or
prospective mortgagee or beneficiary under any deed of trust of the Building or
any part of the Project.  Tenant's failure to deliver such a certificate within
such time will be conclusive evidence of the matters set forth in it.  Landlord
agrees to execute an estoppel certificate in form satisfactory to it within 5
business days of a request by Tenant and receipt of the form of certificate.

24.8  Attorneys' Fees.  If Landlord and Tenant litigate any provision of this
Lease or the subject matter of this Lease, the unsuccessful litigant will pay to
the successful litigant all costs and expenses, including reasonable attorneys'
fees and court costs, incurred by the successful litigant at trial and on any
appeal.  If, without fault, either Landlord or Tenant is made a party to any
litigation instituted by or against the other, the other will indemnify the
faultless one against all loss, liability, and expense, including reasonable
attorneys' fees and court costs, incurred by it in connection with such
litigation.

24.9  No Merger. The voluntary or other surrender of this Lease by Tenant or the
cancellation of this Lease by mutual agreement of Tenant and Landlord or the
termination of this Lease on account of Tenant's default will not work a merger,
and will, at Landlord's
<PAGE>

option, (a) terminate all or any subleases and subtenancies or (b) operate as an
assignment to Landlord of all or any subleases or subtenancies. Landlord's
option under this Article 24.9 will be exercised by written notice to Tenant and
all known subleases or subtenants in the Premises or any part of the Premises.

24.10  Holding Over.  Tenant will have no right to remain in possession of all
or any part of the Premises after the expiration of the Term and Landlord may,
at its option, re-enter and take possession of the Premises, reserving its
rights to collect damages sustained by reason of Tenant's unlawful retention of
possession of the Premises or any part thereof.  If Tenant remains in possession
of all or any part of the Premises after the expiration of the Term with the
express written consent of Landlord: (a) such tenancy will be deemed to be a
periodic tenancy from month-to-month only; (b) such tenancy will not constitute
a renewal or extension of this Lease for any further term; and (c) such tenancy
may be terminated by Landlord upon the earlier of 30 days' prior written notice
or the earliest date permitted by law.  In such event, Monthly Rent will be
increased to an amount equal to 200% of the Monthly Rent payable during the last
month of the Term and any other sums due under this Lease will be payable in the
amount and at the times specified in this Lease.  During such month-to-month
tenancy, Tenant will observe every other term, condition, and covenant contained
in this Lease.

24.11  Notices.  Any notice, request, demand, consent, approval, or other
communication required or permitted under this Lease must be in writing and will
be deemed to have been given when personally delivered, sent by facsimile with
delivery acknowledged by the sending machine, deposited with any nationally
recognized overnight carrier that routinely issues receipts, or deposited in any
depository regularly maintained by the United States Postal Service, postage
prepaid, certified mail, return receipt requested, addressed to the party for

Orange, NJ 07082 (Fax: 973-325-8201) if to Landlord.  Either Landlord or Tenant
may add additional addresses or change its address for purposes of receipt of
any such communication by giving 10 days' prior written notice of such change to
the other party in the manner prescribed in this Article 24.11.

24.12  Severability.  If any provision of this Lease proves to be illegal,
invalid, or unenforceable, the remainder of this Lease will not be affected by
such finding, and in lieu of each provision of this Lease that is illegal,
invalid, or unenforceable a provision shall be deemed added as a part of this
Lease as similar in terms to such illegal, invalid, or unenforceable provision
as may be possible and be legal, valid, and enforceable.

24.13  Written Amendment Required.  No amendment, alteration, modification of,
or addition to the Lease will be valid or binding unless expressed in writing
and signed by Landlord and Tenant.  Tenant agrees to make  any modifications of
the terms and provisions of this Lease required or requested by any lending
institution providing financing for the Building, or Project, as the case may
be, provided that no such modifications will materially adversely affect
Tenant's rights and obligations under this Lease.
<PAGE>

24.14  Entire Agreement.  This Lease, the exhibits and addenda, if any, contain
the entire agreement between Landlord and Tenant.  No promises or
representations, except as contained in this Lease, have been made to Tenant
respecting the condition or the manner of operating the Premises, the Building,
or the Project.

24.15  Captions.  The captions of the various articles and sections of this
Lease are for convenience only and do not necessarily define, limit, describe,
or construe the contents of such articles or sections.

24.16  Notice of Landlord's Default.  In the event of any alleged default in the
obligation of Landlord under this Lease, Tenant will deliver to Landlord written
notice listing the reasons for Landlord's default and Landlord will have 30 days
following receipt of such notice to cure such alleged default or, in the event
the alleged default cannot reasonably be cured within a 30-day period, to
commence action and proceed diligently to cure such alleged default.  In the
event of an emergency which threatens to halt Tenant's operations, or poses
danger to health and safety on an imminent basis, Tenant can demand landlord to
cure immediately following such notice, failing which cure Tenant can act to
effectuate such cure on behalf of Landlord.

24.17  Authority.  Tenant and the party executing this Lease on behalf of Tenant
represent to Landlord and Landlord so represents to Tenant, that such party is
authorized to do so by requisite action of the board of directors or partners,
as the case may be, and agree upon request to deliver to Landlord a resolution
or similar document to that effect.  Landlord shall deliver a resolution or
certified extract thereof verifying its authority to enter into this Lease upon
request of Tenant, it being understood that Landlord shall have the right to
protect from disclosure the names of its members other than the Managing Member.

24.18  Brokers.  Tenant represents and warrants that it has not consulted or
negotiated with any broker, finder or agent with regard to the Premises except
the broker named in Section 1.1, if any.  Tenant agrees to hold Landlord
harmless and indemnify Landlord against all costs, expenses, attorney's fees, or
other liability for commissions or other compensation or charges claimed by any
broker, finder or agent claiming the same by, through or under Tenant and such
indemnity shall survive the expiration or earlier termination of this Lease.
Landlord agrees to pay in full the leasing broker fees in accordance with the
attached Exhibit G, to Cushman and Wakefield of New Jersey, Inc. and to so
indemnity Tenant against any claims by said broker for such fees or for claims
of any other broker claiming by or through Landlord.

<PAGE>

24.21  No Easements for Air or Light.  Any diminution or shutting off of light,

Building will in no way affect this Lease or impose any liability on Landlord.

24.22  Intentionally Blank.

24.23  Tax Credits.  Promptly after Landlord's demand, Landlord and Tenant will
prepare a detailed list of the leasehold improvements and fixtures and their
respective costs for which Landlord or Tenant has paid.  Landlord will be
entitled to all credits and depreciation for those items for which Landlord has
paid by means of any Tenant finish allowance or otherwise.  Tenant will be
entitled to any tax credits, and depreciation for all items for which Tenant has
paid with funds not provided by Landlord.

24.24  Financial Reports.  Within 15 days after Landlord's request, Tenant will
furnish Tenant's most recent annual report including audited financial

24.25  Landlord's Fees.  Whenever Tenant requests Landlord to take any action or
give any consent required or permitted under this Lease, Tenant will reimburse
Landlord for all of Landlord's reasonable costs incurred in reviewing the
proposed action or consent, including without limitation reasonable attorneys',
engineers' or architects' fees, within 10 days after Landlord's delivery to
Tenant of a statement of such costs.  Tenant will be obligated to make such
reimbursement without regard to whether Landlord consents to any such proposed
action.

24.26  Binding Effect.  The covenants, conditions, and agreements contained in
this Lease will bind and inure to the benefit of Landlord and Tenant and their
respective heirs, distributees, executors, administrators, successors, and,
except as otherwise provided in this Lease, their assigns.

shall be cumulative and none shall exclude any other rights and remedies allowed
by law.

<PAGE>

24.31  Force Majeure.  When a period of time is herein prescribed for any action
to be taken by Landlord, Landlord shall not be liable or responsible for, and
there shall be excluded from the computation for any such period of time, any
delays due to strikes, riots, acts of God, shortages of labor or materials, war,
regulations or restrictions or any other causes of any kind whatsoever which are
beyond the control of Landlord.  When a period of time herein is prescribed for
any action to be taken by Tenant, there shall be excluded from such computation
any periods of time wherein Tenant was prevented from complying by strikes,
riots, acts of God, shortages of labor or materials, war, regulations or
restrictions or any other causes of any kind whatsoever which are beyond the
control of Tenant, provided that this provision shall have no effect and shall
not work to extend or excuse timely compliance with any financial and payment
obligations of Tenant.

24.32  Third Party Beneficiary.  It is specifically understood and agreed that
no person shall be a third party beneficiary hereunder, and that none of the
provisions of this Lease shall be for the benefit of or be enforceable by anyone

                                OPTION TO EXTEND

A. Tenant may extend this Lease on three occasions: The first for a period of 10
years, the second for a period of 10 years, and the third for a period of 10
years (each, the "Extension Term") beginning the day after the Lease Expiration
Date, upon the same terms and conditions of the Lease, except that:

1.  the Term is modified to include the Extension Term when an option is
    properly exercised;

2.  the Monthly Rent for the Extension Term shall be calculated as follows:

    During the fourteenth year of the original term of the Lease, Tenant
shall have the option of selecting a method of calculating rent for the first
five years of the first extension period. Tenant shall exercise such option by
written notice to Landlord of Tenant's election to calculate rent in accordance
with either sub-paragraphs (a) or (b) below;

    (a)  115% of rent being paid during the last year of the Term.; or

    (b)  the lesser of 120% of rent being paid during the last year of
         the term or an adjusted annual rent which is reflective ot the
         increase in the Consumer Price Index ("CPI") and computed in the
         following manner:

         (i)  The applicable CPI shall be the Consumer Price Index for
    Urban Wage Earners and clerical Workers, New York, N.Y. -Northeastern, New
    Jersey. The adjusted rent shall be equal to a fraction, the denominator of
    which shall be the CPI for March, 2015 (which is the month immediately
    proceeding the 16th year of the Lease) (the "Base Index"), and the numerator
    of which shall be the CPI published for February, 2020, (which is the month
    immediately proceeding the expiration date of the Lease) (the "Adjustment
    Index"), multiplied by the rent being paid during the least year of the
    term.

In the event Tenant fails to exercise its option of election, as set forth
above, during the fourteenth year of the original term, rent will be calculated
in accordance with sub-paragraph (a) above.

B. The rent for the second five years of the first extension period shall be
calculated as above based upon the election which must be made prior to March
31, 2020, failing which rent shall be calculated in accordance with
paragraphA2(a) above.

C. The rent for the second and third extension periods shall be calculated in
accordance with paragraph A2 of this Exhibit D with elections to select rent to
be made five years in advance of each Extension Term, with Tenant electing to
pay rent for each 5 year period during the Extension Term in accordance with the
calculations as set forth in paragraph A2 of this Exhibit D, with the exception
that the Base Index shall be the date which is the month and year which is
immediately prior to the commencement of the Extension Term for which rent is
being selected, and the Adjustment Index shall be the date which is the month
and year which is five years before the end of the Extension Term for which rent
is being selected. Such calculations shall be consistent with the examples as
set forth in Article 4.2.

                                       34
<PAGE>

D. To exercise this Option to Extend, Tenant must:

1. Not then be in default of the Lease;

2. Give Notice in writing to Landlord that Tenant is exercising its Option to
Extend at least 9 months but not more than 18 months before the Lease Expiration
Date ("Tenant's Notice to Extend Term"). Parties agree that in the event Tenant
does not exercise either of the three extension term options, Tenant shall give
notice of its intention to vacate at least fifteen months prior to the Lease
Expiration Date as same may be extended in accordance with this Option. In the
event Tenant gives less than fifteen months notice, it shall pay Landlord at
termination one months rent for each months notice which is less than the
required fifteen. (e.g. If notice is given ten months before termination of the
Lease, Tenant will pay Landlord at the lease termination an amount equal to five
months rent).

3. Have provided such financial reports and statements required under the Lease.

4. Have elected the rent in accordance with Paragraphs 2(a) or (b) of the
   foregoing Section A.

Failure of Tenant to observe or comply with the terms of this Option to Extend
shall render the option null and void. Landlord shall not be required to extend
the Term of this Lease if, in its reasonable judgment, Tenant's financial
condition may impair its ability to meet its obligations during the Extended
Term.
