                              PART 1 - THE SCHEDULE

                                    SECTION B
                        SUPPLIES/SERVICES AND PRICES/COST

B.1      MINIMUM AND MAXIMUM AMOUNTS, INDEFINITE DELIVERY INDEFINITE QUANTITY

         (a)      This is an Indefinite Delivery Indefinite (a) Quantity (IDIQ)
                  subcontract utilizing Time and Materials (T&M) and Firm Fixed
                  Price (FFP) Subcontract Task Orders in accordance with FAR
                  16.5.

                  The use of a hybrid IDIQ subcontract will enable CSC to issue
                  task orders using a variety of contract types. CSC may issue
                  Subcontract Task Orders providing for one of the following
                  bases of compensation:

                  Time & Material (T&M)

                  Firm Fixed Price (FFP)

B.2      SUPPLIES/SERVICES AND PRICES/COSTS

         (a)      The Seller, acting as an independent contractor and not as an
                  agent of the Buyer, shall furnish all materials, personnel,
                  facilities, support and management necessary to provide the
                  supplies and services as set forth in accordance with the
                  Statement of Work and the Seller's rate proposal dated
                  12/03/2003, incorporated herein by reference.

         (b)      Statements of Work, specific periods of performance and
                  funding will be obligated via Subcontract Task Orders which
                  will be incorporated herein by modification(s) to this
                  subcontract in accordance with Section G.4, entitled
                  "Ordering".

                  (1)      For T&M Subcontract Task Orders, the quantity of
                           hours ordered of each labor category will be
                           specified as deliverable hours billable at the rates
                           specified in this Subcontract Agreement. Profit on
                           travel and ODCs on T&M Subcontract Task Order is not
                           allowable. The cumulative extended total of all labor
                           categories ordered plus ODCs (if allowed) will define
                           the task order ceiling price. Any allowable ODCs will
                           be specified in the Subcontract Task Order. The Buyer
                           will not reimburse the Seller for costs incurred
                           beyond the ceiling price, for hours not delivered,
                           for hours delivered but in excess of the quantities
                           ordered for a particular labor category, or for
                           travel exceeding the estimated travel amount.

                  (2)      For FFP Subcontract Task Orders, the quantity of each
                           item, or labor category ordered will be multiplied
                           against the price (rate) listed in the Subcontract
                           Task Order, and the cumulative extended total of all
                           items ordered will define the FFP for those items.
                           Any allowable ODCs will be specified in the
                           Subcontract Task Order. Partial payment of the
                           Subcontract Task Orders FFP may be negotiated based
                           on an attainment of progress milestones.

                  (4)      Based upon requirements items identified during
                           Subcontract Task Order preparation, Buyer shall be
                           responsible for purchasing and providing to the
                           Seller any tangible item (i.e., ODCs) required for
                           performance on this contract. The Seller will be
                           reimbursed only for those ODC items specified in the
                           Subcontract Task Order as reimbursable by the Buyer.

         (c)      The Seller's rates will be incorporated to each Task Order.

B.3      VALUE

         This Agreement is issued under Government Prime Contract number
         COW-8-C-0051, with a DPAS Rating of: Unrated. For Government audit
         purposes only, the value of this subcontract agreement is $500,000.00.
         Subcontract Task Order(s) added by Modification(s) hereto will
         authorize the billable funding (reference Section G.4, Ordering).

B.4      EXERCISE OF OPTIONS

         This subcontract contains two (2) types of options: options to extend
         the period of performance of the subcontract and options to increase
         the quantity of labor hours available for each year of subcontract
         performance. The Buyer may exercise the subcontract options for
         extensions to the period of performance to the same extent that the
         options of the prime contract are exercised.

         In accordance with the provisions of the applicable FAR clauses
         contained in this subcontract regarding the exercise of options, all
         options will be exercised in writing through the issuance of
         modifications to the subcontract signed by the Subcontract
         Administrator. The increase quantity options (IQOs) are provided to
         allow CSC to account for unforeseen increases in requirements above the
         basic requirements of any subcontract year. The specific IQO may be
         exercised during any particular year to increase the quantity for that
         period; however, the IQO does not affect the period of performance of
         the subcontract or the period in which the option was exercised.

                                STATEMENT OF WORK

C.1      GENERAL STATEMENT OF WORK

         The following Statement of Work documents are incorporated by reference
         from the INS STARS RFP Documents. The scope of work noted in the
         documents is general in nature to the INS STARS Program. The
         subcontractor will be provided with specific Subcontractor Task Orders
         by CSC to direct specific work in support of the General Statement of
         Work. Attachment I of this document includes a detailed Subcontractor
         Proposal for work that the subcontractor will provide.

                  (a)      INS STARS General SOW Umbrella 7-2, dated July 2,
                           2001

C.2      MANAGEMENT AND ADMINISTRATION

         The Buyer intends to manage all work assigned under the contract.
         Therefore, the Seller will not generally submit subcontractor
         management and administration costs. The Buyer expects there may be
         certain Subcontract Task Orders that will require management efforts by
         the Seller. In these cases, specified management and administration
         requirements will be included in the Subcontract Task Order and priced
         by the Seller.

C.3      ADDITIONAL EFFORTS

         Subcontract Task Order Specific Statements of Work will be agreed upon
         and incorporated into the subcontract through issuance of a CSC
         Subcontracting Officer signed Subcontract Task Order or Subcontract
         Modification. (Issuing an STO will not require a contract modification
         unless the Subcontract Task Order causes the total cost of all
         Subcontract Task Orders to exceed the current contracted value. The
         Seller shall notify the Buyer when 75 percent (75%) of the subcontract
         value has been reached.).

D.1      PACKAGING AND MARKING

         All materials shipped or mailed under this contract shall be afforded
         the degree of preservation, packaging, and packing required to prevent
         deterioration and damage due to the hazards to which they may be
         subjected during shipment, handling, and storage. All preservation,
         packaging, and packing for shipment or mailing shall be in accordance
         with good commercial practice and adequate to ensure acceptance by
         common carrier and safe transportation at the most economical rate(s).

D.2      DELIVERABLES AND MARKING

         The Seller shall mark all deliverables with the contract number; title
         of the deliverable; date due; and preparer's name. In addition, when
         applicable, the Seller shall mark the deliverables with the Subcontract
         Task Order name/number; CSC Task Manager name; and the document status
         as a draft, final, or update.

         Additional deliverables marking information will be provided on the
         Subcontract Task Order issued when applicable. For example, for the
         shipment of prototype and pilot systems, the CSC will provide specific
         packaging and delivery instructions as may be required to ensure the
         safe shipment of the system.

D.3      SUBCONTRACTOR DOCUMENTATION AND OTHER DELIVERABLES

Due      to the nature of the work to be performed under this subcontract, the
         documents to be delivered include written reports, specifications, test
         documentation, and in some instances, drawings or sketches. The Seller
         shall establish and maintain a contract reporting and documentation
         preparation process that provides the highest quality products in a
         timely and cost effective manner. All documents produced under the
         contract shall comply with Government guidelines, directives, and
         standards, if applicable, or with industry standard reporting forms and
         formats, as specified in
          Subcontract Task Orders.

         In addition to providing the services specified by Subcontract Task
         Orders under this subcontract, the Seller may be required to submit
         prototype hardware and software products, test and evaluation
         equipment, and other development products. The Seller shall ensure that
         all products are delivered with all associated components necessary to
         render the product operational and with complete sets of documentation,
         instructions, or other literature that may be specified in Subcontract
         Task Orders.

                  All subcontract administration will be effected by the
                  Subcontract Administrator (SA), or designee. Communications
                  pertaining to contractual administrative matters will be

                  Office (BMO), Business/Contracts Manager. The word "Buyer" as
                  used throughout this contract or its attachment refers
                  specifically to the SA. The SA is the only person authorized
                  to approve changes in any of the requirements of this
                  contract, and notwithstanding any provisions contained
                  elsewhere in this contract, said authority remains solely with

                  be effected without a written modification to the subcontract
                  executed by the SA authorizing such changes. Should schedule
                  conditions warrant a "rapid reaction", the SA may issue a
                  verbal authorization to initiate work. Should this occur,
                  written confirmation shall be provided to the Seller within
                  five (5) calendar days following the verbal authorization to
                  proceed.

                  possible lines of inquiry, or otherwise supplements the scope
                  of work. "Technical Direction" must be confined to the general
                  scope of work set forth herein and shall not constitute a new
                  assignment, nor supersede or modify any other clause of this
                  contract. To be valid, technical direction:

                  o        Must be issued in writing consistent with the general

                  o        Provide technical guidance in the performance of the
                           contract;

                  o        Receive, review, and approve or accept (but not
                           reject) services and products delivered under the
                           contract;

                  o        Certify invoices/vouchers for payment based on the

                  Section E, the authority to reject deliverables or deny
                  payments under the contract rests with the Subcontract
                  Administrator.

                  and/or modify any of the expressed terms, conditions,
                  specifications, or cost of the contract. If as a result of
                  technical discussions, it is desirable to alter/change
                  contractual obligations or the Subcontract Task Order, the SA
                  shall issue such changes in writing.

                  otherwise affect the terms of this Subcontract. Technical
                  coordination shall not result in any action that:

                  a.       constitutes an assignment of additional work outside
                           the SOW or the Subcontract Task Order,

                  b.       constitutes a change as defined in the contract
                           clause entitled "Changes" for Firm Fixed Price, Time
                           and Material and Cost Reimbursement contracts,

                  c.       causes an increase in the total Subcontract ceiling,
                           task order price, or the time required for contract
                           or Subcontract Task Order performance,

                  d.       changes any of the expressed terms, conditions or
                           specifications of the Subcontract or Subcontract Task
                           Order, or

                  e.       interferes with the Seller's right to perform the
                           terms and conditions of the contract.

G.4      ORDERING

         The INS will issue Request for Task Order Proposals to the Buyer. The
         Buyer will be responsible for submitting a competitive Task Order
         Proposal. The Seller will support the preparation of the proposal to
         the appropriate extent. The Seller will also support the Task Order
         Planning Process which forms the basis for Task Order Management. Upon
         award to the Buyer by the INS, the Buyer will issue a Subcontract Task
         Order according to the following Process:

                                       19
<PAGE>

         a)       Within the scope of the Statement of Work identified in
                  Section C and Attachment I, the Subcontracts Administrator
                  will issue written Subcontract Task Orders to the Seller.
                  Individual task(s) will be communicated to the Seller by
                  Subcontract Task Order documents wherein the work to be
                  performed is described in terms of scope, deliverables,
                  schedule, milestones, and funding. The procedure for
                  establishing tasks will be as follows:

                  Each task statement will:

                  (i)      State the specific requirements and objectives of the
                           task.
                  (ii)     List appropriate reference material
                  (iii)    State task accomplishment schedule
                  (iv)     Identify data requirements (v) Identify a specific
                           Buyer Task Monitor who will be the technical point of
                           contact for the Subcontract Task Order.
                  (vi)     Specify the CSC WBS/cost account numbers to be
                           charged for the work
                  (vii)    Specify what reports if any, that will be required of
                           the subcontractor
                  (viii)   Specify allowable management functions
                  (ix)     Specify allowable ODCs

         b)       Upon receipt of the task statement, the Seller shall meet with
                  the Buyer to develop jointly a plan for the budget and
                  execution of the task. Seller shall then submit a cost (or
                  price for a FFP Subcontract Task Order) proposal consisting of
                  the time-phased monthly full-time equivalent staff and cost to
                  complete the work in each CSC cost account. In addition, the
                  proposal shall include, for the overall task, the man-hour
                  requirements (by category of skill), and costs, to complete
                  the task. The proposal shall identify and provide rationale
                  for all non-labor cost elements (allowed by the Subcontract
                  Task Order and required for the task performance. After
                  review, evaluation, negotiation, subsequent acceptance of the
                  proposal, the Seller(s) will be authorized by a Subcontract
                  Task Order/modification, to proceed with the work either as
                  proposed or identified by Buyer. Note that Subcontract Task
                  Order Proposal development costs are not recoverable.

         c)       Buyer will decide the mix of effort by each Seller(s) for
                  every Task Order and issue appropriate Subcontract Task
                  Orders. This mix will depend on the nature of the work,
                  recognition as experts, leaders, or niche area expertise,
                  small business concerns and/or extent of any Organizational
                  Conflict of Interest limitations. In the case of relatively
                  high dollar value requirements, it is likely that more than
                  one team member will be utilized. Team members will be aware
                  of their participation prior to award of any individual member
                  Subcontract Task Order.

         d)       The Seller is not authorized to commence task performance
                  prior to issuance of the Subcontract Task Order by the
                  Subcontract Administrator as outlined in Section G.3 above.
                  Any work performed not at the specific direction of the
                  Buyer's Subcontract Administrator is solely at the Seller's
                  risk and the Buyer is not obligated to reimburse Seller for
                  such work.

                                       20

         e)       All Subcontract Task Orders are subject to the terms and
                  conditions of this Agreement. In the event of conflict between
                  a Task Order and this Agreement, the Agreement shall control.

G.5      MODIFICATION/WAIVER

         No modification of this Agreement (including any additional or
         different terms of the Seller) shall be binding on Buyer unless agreed
         to in writing and signed by Buyer's Subcontracts Administrator. No
         course of dealing or failure by Buyer to strictly enforce any term
         right or condition of this Agreement shall be construed as a waiver of
         such term, right or condition.

G.6      SEVERABILITY

         If any provision of this Agreement is or becomes void or unenforceable
         by force or operation of law, the other provisions shall remain valid
         and enforceable.

G.7      DEFAULT

         Seller is in default upon the occurrence of any one or more of
         the following: (1) Seller fails to make delivery of supplies or fails
         to perform the services within the time specified in this order; (2)
         Seller fails to perform in accordance with the provisions of this
         order; or (3) Seller so fails to make progress as to endanger
         performance of this order in accordance with its terms. In these cases,
         Buyer shall, in writing, provide a ten (10) day period (or more if
         authorized in writing by the Buyer) within which Seller may cure its
         default prior to Buyer's terminating the order for default.

G.8      REMEDIES FOR DEFAULT

         Buyer, by written notice to Seller, may terminate this order, in whole
         or in part, if Seller is in default. Upon such termination, Buyer may
         procure, upon such terms as it shall deem appropriate, supplies similar
         to those so terminated, in which case Seller shall continue performance
         of this order to the extent not terminated and shall be liable to Buyer
         for any excess cost for such similar supplies. As an alternate remedy,
         and in lieu of termination for default, Buyer, at its sole discretion,
         may elect (1) to extend the contract delivery schedule, and/or (2) to
         waive other deficiencies in Seller's performance, in which case an
         equitable reduction in the Purchase Order price shall be negotiated. If
         the failure to perform is caused by the default of a Subcontractor at
         any tier and if such default arises out of causes beyond the control of
         both Seller and Subcontractor and without the fault or negligence of
         either of them, Seller shall not be liable for any excess costs for the
         failure to perform, unless the supplies or services to be furnished by
         Subcontractor were obtainable from other sources in sufficient time to
         permit Seller to meet the required delivery schedule. The rights and
         remedies of the Buyer provided in this clause shall not be exclusive
         and are in addition to any other rights and remedies provided by this
         order or by law or equity. Failure of Buyer to insist on strict
         performance shall not constitute a waiver of any of the provisions of
         this order or waiver of any other default of Seller.

G.9      ORDER OF PRECEDENCE

         The rights and obligations of the parties hereto shall be subject to
         and governed by PARTS I through IV of this Subcontract. To the extent
         of any inconsistency between the Sections in PART I, "The SCHEDULE"
         they shall be resolved in writing by mutual agreement of the parties.
         As to any inconsistency between the other PARTS or any specifications

G.11     LABOR REPORTING-TES

         TES is an Interactive Voice Response System (IVRS) developed by CSC
         Corporate MIS to record hours worked. TES will be provided by CSC and
         is required for all Subcontractors on the INS Stars Program. All time
         for a given week must be entered into the system no later then 3 PM on
         each Friday and will include any hours worked beginning from 12:01am
         the previous Saturday morning. The CSC TM will coordinate appropriate
         training in the use of TES. The Subcontractor will select an individual
         to approve the time recorded by Subcontractor Personnel in TES weekly -
         not later than 5pm each Friday. CSC personnel will verify the time
         charged by Subcontractor Personnel. Corrections to already approved
         hours are to be done on a Subcontractor Correction Request form and
         signed/approved, in ink by the Subcontractor and submitted to the CSC
         Technical Monitor. If the Subcontractor has any problems/issues with
         labor hours submitted into TES, CSC must be notified within 30 days or
         risk being paid for the labor hours in question.

         Time entry will include a multi character Project Code and a multi
         character Assignment Code based upon the CSC WBS. TES shall provide
         electronic files for the Subcontractor. The files shall contain the
         labor information entered. In addition, an associated hardcopy of the
         information for each organization shall also be provided.

         Payment will be made to the Subcontractor based on APPROVED TES data,
         in accordance with the invoice instructions of this subcontract.

                                    SECTION H
                               SPECIAL PROVISIONS

H.1      CONFLICT OF INTEREST (FAR 9.5)

         It is understood and agreed that the Seller, under the terms of this
         Subcontract, or through the performance of the Statement of Work made a
         part of this Subcontract, is neither obligated nor expected to deliver
         or provide material or perform work, which will place the Seller in an
         Organizational Conflict of Interest, which could serve as a basis for
         excluding the Seller from supplying products or services to the
         Immigration and Naturalization Service (INS) or other Government
         agencies. Further, during the course of this contract, the Buyer will
         not knowingly unilaterally direct the Seller to perform work, in
         contravention of the above understanding. It will be the Seller's
         responsibility to identify any situation in which the potential for an
         Organizational Conflict of Interest exists. However, prior to the
         execution of any Subcontract Task Order or amendment thereto, if the
         Subcontract Administrator discerns the potential for an Organizational
         Conflict of Interest insofar as the work to be performed there under is
         understood to involve the preparation of a complete specification of
         materials leading directly, predictably and without delay to a
         Statement of Work which will be used in the competitive procurement of
         a system, the Buyer shall notify the Seller, and the parties shall
         mutually take action to resolve any potential organizational conflict
         of interest.

H.2      CONFERENCES

         The Buyer's Subcontract Administrator, or his duly authorized
         representative, may call a conference from time to time as deemed
         necessary to discuss any phase of performance under the Subcontract.
         All discussions, problems encountered, solutions reached, and
         evaluations made during any conference shall be documented in the next
         Management Level Monthly Progress Report for current reporting period.
         In any case, such reporting shall not, in and of itself, constitute
         formal direction to and/or Subcontract Administrator acceptance of the
         topics discussed.

H.3      TRAVEL

         (a)      Official travel of Seller personnel away from their duty
                  station that was not identified in the negotiated Subcontract
                  Task Order shall not be undertaken unless, advance, prior
                  approval has been obtained from the Buyer TM. If travel causes
                  additional costs to the Subcontract Task Order, written
                  approval by the Buyer is REQUIRED.

         (b)      The Seller's request for travel shall be in writing and
                  contain the dates, locations, and estimated costs of the
                  travel.

         (c)      Cost associated with the Seller's travel shall be in
                  accordance with FAR Part 31.205-46.

                                       24
<PAGE>

H.4      WORK AT A GOVERNMENT SITE

         If the Subcontractor (or any of its subcontractors and their employees)
         is assigned to work at INS facilities, then the Subcontractor shall
         comply with the regulations governing access to, operation of, and
         conduct while in or on the premises. The Subcontractor shall ensure
         that all work is performed in a manner that does not interrupt or
         interfere with the conduct of Government business.

H. 5     INSURANCE SCHEDULE

         In accordance with FAR 52.228-7, "Insurance Liability to Third Persons
         APR 1984," the Subcontractor shall secure, pay the premiums for and
         keep in force until the expiration of this contract, and any renewal
         thereof, adequate insurance as provided below, such insurance to
         specifically include liability assumed by the Seller under this
         subcontract.

         a.       Property damage liability with a limit of not less than
                  $100,000 for each accident.

         b.       Automotive bodily injury liability insurance with limits of
                  not less than $200,000 for each person and $500,000 for each
                  accident, and property damage liability insurance, with a
                  limit of not less than $40,000 for each accident.

         Each policy of insurance shall contain an endorsement that any
         cancellation or material change in the coverage adversely affecting the
         Buyer's interest shall not be effective unless the insurer or the
         Seller gives written notice of cancellation or change, as required by
         the Buyer. When the coverage is provided by self-insurance, the Seller
         shall not change or decrease the coverage without the Subcontract
         Administrator's prior approval.

         A certificate of each policy of insurance shall be furnished to the
         Subcontract Administrator within ten (10) days after notice of award
         certifying, among other things, that the policy contains the
         aforementioned endorsement. The insurance company providing the above
         insurance shall be satisfactory to the Buyer. Notices of policy changes
         shall be furnished to the Subcontract Administrator.

H.6      NOTIFICATION REQUIREMENTS UNDER TIME AND MATERIAL AND COST
         REIMBURSEMENT CONTRACTS

         Seller notification requirements for FAR 52.232-20(b) "Limitation of
         Cost" for CPFF, CPIF and CPAF Subcontract Task Orders, and FAR
         52.2327(c) "Payments under Time and Materials and Labor Hours" for T&M
         Subcontract Task Orders (clauses are in Section I by reference), shall
         be accomplished only by separate correspondence directed to the
         Subcontract Administrator with copies to the Subcontract Task Monitor
         and Business Management Office. No other form of "notification" (e.g.,
         mention in any type of monthly progress or status report) will effect
         compliance. Further, notification to any individual other than the
         Buyer's Subcontract Administrator shall not constitute compliance with
         this requirement.

H.7      PERSONNEL QUALIFICATIONS

         (a)      The labor category descriptions in each Task Order or Position
                  Designation Determination Form depict the types of personnel
                  that shall typically be provided by the Seller in support of
                  task orders and are incorporated into this Subcontract.

H.8      KEY PERSONNEL

         (a)      The personnel specified as key personnel are considered
                  essential to the work performed under the STARS Program
                  subcontracts. Before diverting the specified individuals to
                  other programs, the Subcontractor shall notify the Subcontract
                  Administrator no less than 30 calendar days in advance and
                  shall submit justification (including the names and resumes of
                  the proposed substitutions) in sufficient detail to permit
                  evaluation of the impact on the program. The proposed
                  substitutions shall possess qualifications equal or superior
                  to those of the key person(s) being replaced. No diversion or
                  substitution shall be made by the Subcontractor without the
                  written consent of the Subcontract Administrator. The list of
                  key personnel set forth in this clause may be amended from
                  time to time during the contract either to add or delete
                  personnel, as appropriate.

                  Substitution or diversion of key personnel shall be handled as
                  specified in the preceding paragraph, with the exception that
                  during the FIRST 180 DAYS of this contract, no key personnel
                  substitutions will be permitted unless such substitutions are
                  necessitated by an individual's sudden illness, death, or
                  termination of employment. In any of these events, the
                  Subcontractor shall promptly notify the Subcontract
                  Administrator and provide the information required by the Key
                  Personnel clause. The Government and CSC reserve the right to
                  identify or require the designation of key personnel on a
                  Subcontract Task Order Task basis during subcontract
                  performance.

H.9      SECURITY

         This document is unclassified; however, the classification of the work
         to be performed on specific Task Orders issued under this contract may
         require security clearances. In that event, the Seller will be advised
         of the requirements in the SOW. The Seller shall follow conscientiously
         the security requirements identified in the SOW and other guidance that
         may be established by the Buyer's Subcontract Administrator.

H.9.1    ACCESS TO CLASSIFIED INFORMATION

         Performance of this contract requires that the Contractor,
         subcontractor(s), vendor(s), etc., (herein known as Seller) require(s)
         access to classified National Security Information (herein known as
         classified information). Classified information is Government
         information, which requires protection in accordance with Executive
         Order 12958, Classified National Security Information, and
         supplementing directives.

                                       26
<PAGE>

         The Seller shall abide by the requirements set forth in the DD Form
         254, Contract Security Classification Specification, provided in
         Section J of the subcontract, and the National Industrial Security
         Program Operating Manual (NISPOM) for the protection of classified
         information at its cleared facility, if applicable, as directed by the
         Defense Investigative Service. If the Seller has access to classified
         information at a Buyer or Government facility, it shall abide by the
         requirements set by that agency.

H.10     NONDISCLOSURE OF SENSITIVE AND/OR PROPRIETARY DATA

         The Seller recognizes that in the performance of this contract it may
         receive or have access to certain sensitive information, including
         information provided on a proprietary basis by carriers, equipment
         manufacturers and other private or public entities. The Seller agrees
         to use and examine this information exclusively in the performance of
         this Subcontract and to take the necessary steps in accordance with
         Buyer regulations to prevent disclosure of such information to any
         party outside the Buyer or Buyer designated support contractors
         possessing appropriate proprietary agreements, as listed in paragraph
         (a) below.

         (a)      Indoctrination of Personnel. The Seller agrees to indoctrinate
                  its personnel who have access as to the sensitive nature of
                  the information and the relationship under which the
                  contractor has possession of or access to the information.
                  Seller personnel shall not engage in any other action, venture
                  or employment wherein sensitive information will be used for
                  the profit of any party other than those furnishing the
                  information. The Seller shall restrict access to
                  sensitive/proprietary information to the minimum number of
                  employees necessary for contract performance.

H.11     BUYER FURNISHED EQUIPMENT, INFORMATION OR SERVICES

         (a)      It is anticipated that for some Subcontract Tas Orders,
                  Government Furnished Equipment (GFE) will be specified in the
                  individual order (at the discretion of the Buyer) with
                  specified delivery dates. Such equipment will be returned to
                  the Buyer upon the conclusion of the subcontract, as specified
                  in the individual Subcontract Task Order, or as directed in
                  writing by the Buyer's Subcontract Administrator.

         (b)      Government Furnished Information (GFI) relevant to the tasks
                  to be performed under this subcontract will be provided to the
                  Seller for use during the performance of the Subcontract Task
                  Order as specified in the orders (at the discretion of the
                  Government or Buyer) with specified delivery dates. These
                  documents will be returned to the Buyer upon the conclusion of
                  the subcontract, as specified in the individual task order, or
                  as directed in writing by the Subcontract Administrator.

         (c)      In the case that GFE or GFI are not provided to the Seller by
                  the specified date, the Task Monitor will be immediately
                  notified by the Seller. The Seller will indicate impact and
                  request direction from the Buyer's TM and Subcontract
                  Administrator.

                                       27
<PAGE>

         (d)      Sellers are responsible and liable for GFE property in their
                  possession pursuant to FAR 52.2451, 52.2452 and 52.2455, as
                  applicable.

H.12     PUBLICITY

         The Seller shall not be unduly restricted from disclosing to the public
         the salient details of the contract arrangement as to meet its SEC
         requirements to report to the public all material events which involve
         the Seller. In all cases the Seller shall not disclose any confidential
         or proprietary information pertaining to the Buyer, nor shall it
         disclose any confidential or proprietary information that pertains to
         the Department of Homeland Security. On the occasions that the Seller
         must disclose salient details to its shareholders of this contract, it
         shall allow the Buyer and or the Department of Homeland Security a
         period not to exceed 48 hours to review and edit such disclosure
         material. Those persons authorized to review and edit such disclosure
         material are the Contract Officers whom represent the Buyer and the
         Department of Homeland Security.

H.13     EMPLOYMENT OF ILLEGAL ALIENS

         Subject to existing laws, regulations, and Executive Orders and other
         provisions of this subcontract, illegal or undocumented aliens shall
         not be employed by the Subcontractor, or subcontractors if applicable,
         to work on, under, or with this contract. The Subcontractor shall
         ensure that this provision is expressly incorporated into any and all
         subcontracts or subordinate agreements issued in support of this
         subcontract.

H.14     DISPUTES

         (a)      If a decision on any question of fact or law is made by the
                  Government's Contracting Officer and such question of fact or
                  law is also related to this Subcontract, said decision, if
                  binding on Buyer under the Prime Contract, shall in turn be
                  binding on Buyer and Seller insofar as it relates to this
                  Subcontract. If Buyer elects to appeal such a decision
                  pursuant to the "Disputes" clause in the Prime Contract, any
                  decision on such an appeal with respect to such question of
                  fact or law, if binding on Buyer under the Prime Contract,
                  shall in turn be binding on Buyer and Seller insofar as it
                  relates to this Subcontract. If Buyer elects not to appeal
                  such decision pursuant to the "Disputes" clause in the prime
                  contract, Buyer shall promptly notify Seller and Subcontract
                  may exercise it rights under paragraph (e) below.

         (b)      If Seller is otherwise affected by any decision made by any
                  representative of the Government on any question of fact or
                  law arising under the Prime Contract that is also related to
                  this Subcontract, from which an appeal under the "Disputes"
                  clause of the Prime Contract is not available, said decision,
                  if binding on Buyer under the Prime Contract, shall in turn be
                  binding on Buyer and Seller insofar as it relates to this
                  Subcontract. If Buyer elects to bring suit against the
                  Government with respect to such decision, a final judgment in
                  any such suit, if binding on Buyer under the Prime Contract,
                  shall in turn be binding on Buyer and Seller insofar as the
                  question decided relates to this Subcontract. If Buyer elects
                  not bring suit against the Government with respect to such
                  decision, Buyer shall promptly notify Seller, and Seller may
                  exercise its right under paragraph (e) below.

                                       28
<PAGE>

         (c)      If Buyer or Seller brings any such appeal or suit as allowed
                  in paragraphs (a) and (b) above, the other party, at its own
                  expense, shall assist in the prosecution thereof in every
                  reasonable manner and shall be afforded reasonable opportunity
                  to participate in the prosecution thereof to the extent such
                  party's interests may be affected.

         (d)      If as a result of any decision or judgment that is binding on
                  Seller and Buyer, as provided above, Buyer is unable to obtain
                  payment from the Government under the Prime Contract for
                  services, or is required to refund or credit to the
                  Government, any amount Buyer has paid Seller, Seller shall, on
                  demand, promptly repay such amount to Buyer, insofar as it
                  relates to this subcontract.

         (e)      Any dispute arising under this Subcontract that is not covered
                  by paragraph (a) or (b) above and which is not settled by
                  agreement of the parties shall be decided by Buyer. Such
                  decision shall be reduced to writing and a copy thereof
                  furnished to Seller. If Seller disagrees with Buyer's
                  decision, Seller shall notify Buyer within thirty (30) days
                  after receipt of such copy. In the absence of such notice,
                  such decision shall be final. If such notice is given by
                  Seller, Seller may proceed to have the dispute settled through
                  appropriate legal action. If Seller proceeds with litigation
                  and, prior to trial, one or more of the questions of fact or
                  law become the subject of a decision covered by paragraph (a)
                  or (b) above, such questions shall be determined in accordance
                  with this clause and the litigation shall be terminated as to
                  such questions.

         (f)      Pending any decision, appeal, or judgment referred to in
                  paragraph (a) or (b) above, Seller shall proceed diligently
                  with performance of this Subcontract unless Buyer otherwise
                  specifies in writing.

         (g)      The rights and obligations described in this clause shall
                  survive completion and final payment of this Subcontract.

         (h)      Nothing contained in this subcontract shall be construed to
                  obligate the Government contracting officer to deal directly
                  with the Seller, or to make the results, of arbitration,
                  judicial determination, or voluntary settlement between Buyer
                  and the Seller binding on the Government.

H.15     NO HIRE CLAUSE

         Buyer and Seller agree that during the period that this agreement is in
         force, including extensions or modifications thereto, and for an
         additional 12 months following this period, neither Buyer nor the
         Seller will actively recruit, or solicit permanent employees of either
         company, or the employees of any of the other Subcontractors; who are
         on active payroll status and are currently participating in this
         Program, without the prior written approval of the party whose employee
         is being considered for employment. This does not prohibit any employee
         from responding to or pursuing employment opportunities through normal
         media channels, i.e. newspapers, professional journals, etc. so long as
         it is not an attempt to avoid the intent of the above restriction.

H.16     PATENT INDEMNITY, GENERAL INDEMNITY

         Each party agrees to defend and hold harmless the other party, Buyer's
         customer and those for whom Buyer may act as an agent from all loss or
         damage by reason of any and all actions or proceedings charging
         infringement of any patent, trademark or copyright by reason of sale or
         use of any services/data furnished hereunder by each party. Each party
         agrees to indemnify and hold the other party harmless from all loss,
         costs or damages arising out of the negligent acts and/or omissions of
         any of the other's employees, agents or representatives.

H.17     ASSIGNMENT

         Seller shall make no assignment of technical responsibilities, monies
         due or to become due hereunder without the prior written permission of
         Buyer. However, nothing contained herein will prohibit Seller from
         assigning monies due or to become due to a bank, trust company, or
         other accredited financial institution, in which event a copy of each
         such assignment will be filed with Buyer before the assignment will
         have any force or effect.

H.22     YEAR 2000 WARRANTY--COMMERCIAL SUPPLY ITEMS

         The Contractor warrants that each hardware, software, and firmware
         product delivered under this contract shall be able to accurately
         process date data (including, but not limited to, calculating,
         comparing, and sequencing) from, into, and between the twentieth and
         twenty-first centuries, including leap year calculations, when used in
         accordance with the product documentation provided by the Contractor,
         provided that all listed or unlisted products (e.g., hardware,
         software, firmware) used in combination with such listed product
         properly exchange date data with it. If the contract requires that
         specific listed products must perform as a system in accordance with
         the foregoing warranty, then that warranty shall apply to those listed
         products as a system. The duration of this warranty and the remedies
         available to the Government for breach of this warranty shall be as
         defined in, and subject to, the terms and limitations of the
         Contractor's standard commercial warranty or warranties contained in
         this contract, provided that notwithstanding any provision to the
         contrary in such commercial warranty or warranties, the remedies
         available to the Government under this warranty shall include repair or
         replacement of any listed product whose non-compliance is discovered
         and made known to the Contractor in writing within ninety (90) days
         after acceptance. Nothing in this warranty shall be construed to limit
         any rights or remedies the Government may otherwise have under this
         contract with respect to defects other than Year 2000 performance.

H.23     YEAR 2000 WARRANTY--NON-COMMERCIAL SUPPLY ITEMS

         The Contractor warrants that each non-commercial item of hardware,
         software, and firmware delivered or developed under this contract shall
         be able to accurately process date data (including, but not limited to,
         calculating, comparing, and sequencing) from, into, and between the
         twentieth and twenty-first centuries, including leap year calculations,
         when used in accordance with the item documentation provided by the
         Contractor, provided that all listed or unlisted items (e.g., hardware,
         software, firmware) used in combination with such listed item properly
         exchange date data with it. If the contract requires that specific
         listed items must perform as a system in accordance with the foregoing
         warranty, then that warranty shall apply to those listed items as a

         subject to, the terms and limitations of any general warranty
         provisions of this contract, provided that notwithstanding any
         provision to the contrary in such warranty provision(s), or in the
         absence of any such warranty provision(s), the remedies available to

         of any listed item whose non-compliance is discovered and made known to
         the Contractor in writing within ninety (90) days after acceptance.

ATTACHMENT I. SUBCONTRACTOR PROPOSAL FOR DCL SYSTEM & GES MAINTENANCE

1.0 SCOPE

    This Statement of Work (SOW) defines the Maintenance Services and
    performance parameters to be provided by the contractor in support of the
    Department of Homeland Security (DHS) Dedicated Commuter Lanes (DCL) system
    and the associated Global Enrollment System (GES). Currently, there are two
    types of DCL systems deployed: NEXUS and SENTRI. The NEXUS system is
    installed at 10 Northern US border locations and the SENTRI system is
    installed at the three Southern US border locations. The scope of this SOW
    addresses the San Diego Port of Entry (POE) only.

2.0 BACKGROUND

    The DCL system was designed to decrease the inspection time for enrolled,
    low-risk travelers who frequently enter the United States by vehicle. Port
    of Entry travel times in conventional lanes have been decreased by removing
    low-risk travelers from those lanes. As a result, inspectors in conventional
    lanes have been able to spend more time focusing on potentially higher risk
    travelers.

    DCL has two versions currently deployed. These versions, NEXUS and SENTRI,
    allow faster processing of low-risk travelers who travel through U.S. Ports
    of Entry (POEs) between Canada and the United States or between Mexico and
    the United States. Users must be enrolled in the Global Enrollment System
    (GES) at each POE region where they might enter before they can use the DCL
    system. The DCL system allows for faster processing at POEs by using radio
    frequency identification (RFID) technology that identifies DCL enrollees. A
    U.S. inspector verifies the identity and status of the traveler after the
    DCL system retrieves the traveler's information and displays it on the
    monitor in the inspector's booth.

3.0 DEFINITIONS AND NOMENCLATURE

         o        DCL - Dedicated Commuter Lane. A single vehicl passage lane
                  dedicated for passage of the enrolled trusted travelers.

         o        GES - Global Enrollment System. The GES captures and stores
                  all pertinent information regarding the enrollees in the DCL
                  system. For NEXUS enrollees only personal information is
                  stored. For SENTRI enrollees both personal and vehicle
                  information is stored.

         o        VALIDATION SUBSYSTEM - The validation subsystem provides an
                  operator interface to the inspector. It can interface with the
                  data server or the lane controller depending on the
                  configuration. The validation subsystem connects to the ges
                  database where information and images of all enrollees and
                  vehicles are retrieved. These images, along with information
                  about the vehicle, are displayed for the inspector to verify
                  the identity of the vehicle and its occupants.

                                       42
<PAGE>

         o        PRIMARY INSPECTION BOOTH - First Inspection are for vehicles
                  entering the U.S Port of Entry.
         o        PRE-PRIMARY - Open space prior to the primary inspection booth
         o        SECONDARY INSPECTION AREA - Intensive examination for suspect
                  vehicles
         o        EGRESS LANES - Exit area for cleared vehicles into the United
                  States.
         o        SYSTEM AVAILABILITY - Expressed as a percentage the actual
                  number of operational hours divided by the total scheduled
                  hours. For example, if the system were down four (4) hours out
                  of a scheduled 80 hours, the achieved actual availability is
                  76/80 or 95%.
         o        RESPONSE TIME - The response time is defined as the time from
                  the receipt of a trouble call by the contractor, until the
                  physical arrival of the contractor's technical representative
                  on the site of the trouble call.
         o        SYSTEM CONFIGURATION - The SYSTEM CONFIGURATION refers to the
                  entire set of equipment acquired by the government and placed
                  in service at a port of entry. It includes, but is not limited
                  to, all Enrollment Center equipment, all Lane Control
                  equipment, and any hardware or software module that is part of
                  the DCL system at the port of entry.
         o        CRITICAL FAILURES - Failures in the DCL system are critical
                  when the malfunction results in the system being in a
                  non-operational state.
         o        NON-CRITICAL FAILURES - Failures in the DCL system are
                  considered non-critical when the malfunction results in the
                  system being in an operational but impaired state.

4.0      OPERATIONAL CONCEPT

         Travelers are required to fill out an application for admittance to the
         DCL program through the DHS enrollment centers located at the
         respective border crossing sites. The DHS enrollment centers facilitate
         travelers entry into the Global Enrollment System (GES) database. The
         enrollment centers process the application along with a set of the
         applicants' fingerprints. The results of this background investigation
         determine whether or not applicants will be accepted into the DCL
         program.

         Once accepted, the applicant is photographed and issued either a
         proximity card (NEXUS) or a transponder (SENTRI). The proximity card
         associated with the NEXUS system includes the traveler's photo, printed
         identifying data, and encoded data that can be read remotely by
         radio-frequency equipment installed in the DCL. The transponder
         associated with the SENTRI system provides similar personal information
         to the inspectors and also provides vehicle information as well.

         The registered travelers and their vehicles (vehicles checked for
         SENTRI only) are periodically checked for any change in background
         status that may affect their eligibility.

         Figure 1 is representative of all NEXUS lanes. A dedicated access lane
         is provided for NEXUS users allowing vehicles to by-pass the general
         traffic lanes and provides fast access into the United States. As the
         vehicle enters the Automated Identification zone, each traveler in the
         NEXUS program presents his/her proximity card to the reader. The
         information on the card is then checked against the GES database for
         verification and any pertinent updated information regarding the
         traveler. All of the information is provided to the lane operator for
         verification at the Validation Subsystem.

         At the Inspector Clearance Area, any missed NEXUS cards are read for
         verification. The inspector then performs the appropriate checks and
         verifications on the driver and all passengers in the vehicle based on
         the information presented via the Validation Subsystem. Authorized
         vehicles are cleared to enter the United States and unauthorized or
         suspected vehicles, drivers, or passengers are directed to the
         Secondary inspection area. Traffic control signals are deployed at the
         DCL exit to direct vehicles through the inspection process.

         Figures 2 and 3 demonstrate the SENTRI lane configurations for San
         Diego POE. A dedicated access lane is provided for SENTRI users
         allowing vehicles to by-pass the general traffic lanes and provides
         fast access into the United States. As the vehicle enters the Automated
         Identification zone, the vehicle's transponder is activated and read by
         the Ergo/Transcore system. The ID data from the transponder is then
         sent to the Validation Subsystem to retrieve the appropriate
         information from the GES database. The retrieved information is
         provided to the lane operator for verification.

         At the Inspector Clearance Area, any missed transponders ID's are read
         for verification. The inspector then performs the appropriate checks
         and verifications on the driver and all passengers in the vehicle based
         on the information presented via the Validation Subsystem. Authorized
         vehicles are cleared to enter the United States and unauthorized or
         suspected vehicles, drivers, or passengers are directed to the
         Secondary inspection area. Traffic control devices (gates, signal
         lights, and bollards) are deployed at the DCL exit to prevent vehicles
         from bypassing the inspection process. At some locations, pipe bollards
         and/or concrete barriers delineate the vehicle path to the U.S. and
         secondary inspection areas.

         GES collects biographic and biometric data about applicants for
         automated inspection systems and stores this information. GES enrolls
         low-risk travelers who are then able to enter the United States by
         verifying their ID and enrollment status with an automated system, to
         accelerate individual examination by a Customs and Border Protection
         (CBP) Inspector. The system provides the enroll travelers with either a
         proximity card (NEXUS) or a transponder for a specific vehicle
         (SENTRI).

         There are two versions of the GES to support: Version 1.8.x and Version
         1.10.x. Version 1.8.x is used to enroll travelers using the NEXUS
         system at a POE. Figure 5 exhibits the GES Version 1.8.x configuration.
         Version 1.10.x is used to enroll travelers and vehicles using the
         SENTRI system at a POE. Figure 6 exhibits the GES Version 1.10.x
         configuration.

7.2      CORRECTIVE MAINTENANCE

For Corrective Maintenance activities the contractor shall diagnose, repair
and/or replace and bring back to full service, all DCL systems covered under
this contract. The contractor will provide all equipment and resources,
including supplies, transportation of parts and skilled labor to fulfill these
requirements.

7.2.1    TROUBLE CALL NOTIFICATION

All trouble calls should be routed through the DHS CBP help desk to ensure that
the proper notification protocol is followed in the reporting of the problem.
All of the following information should be available to help facilitate a swift
corrective action.

                                       51
<PAGE>

         o        Name and title of personnel reporting the problem
         o        Site location, address, and telephone number
         o        Name of the system (i.e., DCL Lane number, Validation System)
         o        A detailed description of the problem and the events tha led
                  to the problem. (For example, enrollee information is not
                  appearing on the inspector's display; system does not seem to
                  be responding.)
         o        A description of when the problem first occurred (what task
                  was being performed, e.g., problem first occurred after
                  several cars passed through the lane. The lane seemed to be
                  running slow, and then it seemed to freeze.)

A trouble ticket is generated from the information and the appropriate person is
notified to resolve the problem.

The notification path to the maintenance contractor shall be setup to ensure
that the performance criteria shall be met. The local area maintenance
contractors shall have company cell phones to allow direct access from the DHS
Help Desk personnel. A central answering service will also be made available to
cover instances when the local contractors are not accessible. The DCL
Inspectors and Supervisors shall also have direct access to the maintenance
contractors; however, the standard protocol requires that the calls be routed
through the DHS Help Desk. Once the DHS Help Desk has been informed of the
problem and a trouble ticket has been generated, direct contact with the
maintenance contractors is permitted. This method has proved effective in the
past and present for maintenance work on the southern US border ports.

7.2.2    TROUBLE CALL RESPONSE TIME

The Response Time for trouble calls are defined for both critical and
non-critical failures.

For all critical failures the contractor shall respond within two (2)
operational hours of notification by a DHS official.

All Non-critical failures require the contractor to respond within eight (8)
operational hours of notification by a DHS official. Where feasible non-critical

categories: Program Manager and Field Engineer as shown below:

      PERSONNEL LABOR CATEGORY        LABOR RATE PER HOUR
------------------------------------  -----------------------------
          Program Manager                       $88.41/hr
------------------------------------  -----------------------------
       Field Service Engineer                   $72.83/hr
------------------------------------  -----------------------------

Applying the labor rates to the required staffing the following table provides
the weekly cost for the effort at the San Diego POE. Total costs for the POE
shall be determined by applying the period of performance (in weeks) identified
in Section 13 to the weekly cost total above.

documents the maintenance effort at the San Diego Port of Entry shall commence.

All other POEs shall begin when the appropriate POE activation contract
documents are signed and the period of performance has been agreed upon by both
parties.

Once a POE has been activated, there shall be a 60 day mobilization and training
period before the maintenance effort is fully operational. Section 15 details
the startup and mobilization efforts.

After the activation contract has been signed by both parties, the activation
shall remain in force for the entire period of performance. The following
exceptions are the only valid causes for early termination of the contract:

                  contractor.

15.0     STARTUP SCHEDULE AND LOGISTICS

The startup effort shall commence upon the contract award and a number of
efforts will need to be accomplished in short order to ensure that the full
maintenance team is in place and fully trained within 60 days of award.

         o        TRAINING AND DEPLOYMENT PLAN - A plan shall be agreed upon for
                  the prime contractor to train the maintenance team leaders.
                  This plan and training time logistics (1 to 2 weeks at CSC
                  mock up or on site) will be completed within 1 week of the
                  contract award. The priorities and area coverage issues will
                  be discussed and formalized as well. All of the documentation
                  associated with the equipment to be maintained will be put
                  together for training purposes.

         o        MAINTENANCE TEAM LEADER TRAINING - An intensive training
                  effort for the maintenance team leaders shall be executed in
                  weeks 3 and 4 of the startup plan. This allows the team
                  leaders to start training the local maintenance staff in week
                  5 when they start working.

         o        LOCAL MAINTENANCE TEAM TRAINING - All local maintenance team
                  training shall be executed at the respective sites. The site
                  team leader and the local maintenance team shall investigate,
                  review and understand all of the required maintenance
                  activities over a 2-4 week period. The prime contractor shall
                  have personnel available for remote issue resolution during
                  this period. During this period the maintenance effort shall
                  be in effect, however, the performance criteria and
                  requirements shall NOT be in effect until the training period
                  is completed.

appropriate, be included in Operating Charges or Real Estate Taxes.

accounting, including, but not limited to, an itemized statement showing (a)
Tenant's proportionate share of the Operating Charges incurred during the
preceding calendar year exceeded the Operating Charges (b) the aggregate amount

estimated payments, then Tenant shall pay the amount of such excess within
thirty (30) days of written notice from the Landlord.

     5.8 Landlord's failure or delay in rendering any particular statement or
statements contemplated by this Article shall not constitute a waiver of
Landlord's right thereafter to render such statement or statements.

     6.2 Tenant shall pay before delinquency any business, rent or other tax or
fee that is now or hereafter assessed or imposed upon Tenant's use or occupancy
of the Premises, the conduct of Tenant's business in the Premises or Tenant's
Furnishings or personal property. If any such tax or fee is enacted or altered
so that such tax or fee is imposed upon Landlord or so that Landlord is
responsible for collection or payment thereof, then Tenant shall deliver a
receipt or proof of payment for any such tax or fee as levied or charged from
time to time or, if requested by Landlord, Tenant shall pay the amount of such
tax or fee and the costs of any collection thereof promptly to Landlord upon
demand.

     6.3 Tenant shall not generate, use, store or dispose of any Hazardous
Materials in or about the Building or the Land. "Hazardous Materials" shall
mean: (a) "hazardous wastes," as defined by the Resource Conservation and
Recovery Act of 1976, as amended from time to time; (b) "hazardous substances,"
as defined by the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended from time to time; (c) "toxic substances," as
defined by the Toxic Substances Control Act, as amended from time to time; (d)
"hazardous materials," as defined by the Hazardous Materials Transportation Act,
as amended from time to time; (e) oil or other petroleum products; and (f) any
substance whose presence could be detrimental to the Building or hazardous to
health or the environment. This restriction shall not be deemed to prevent
Tenant's reasonable use of materials, which are typical in the day to day use of
space for general office purposes.

                                   ARTICLE VII
                       ASSIGNMENT, SUBLETTING OR TRANSFER

     7.1 (a) A "Transfer" is any assignment, subletting, use, occupancy or
transfer of the Premises or any part thereof by or to anyone other than Tenant.
A "Transferee" is any individual, group or entity to whom a Transfer is made.
Tenant shall not Transfer this Lease or any of Tenant's rights or obligations
hereunder, without Landlord's prior written consent, which consent may be
granted or withheld in Landlord's discretion provided that such consent shall
not be withheld or delayed if the following conditions all have been satisfied:

         (i) In the reasonable judgment of the Landlord, the proposed Transferee
is of a character and financial worth such as is in keeping with the standards
of Landlord in those respects for the Building, and the nature of the proposed
Transferee's business and its reputation are in keeping with the character of
the Building and its tenancies.

         (ii) The purposes for which the proposed Transferee intends to use the
Premises or the applicable portion thereof are uses expressly permitted by and
not prohibited by this Lease including, without limitation, the provisions of
Article VI hereof, and by any other lease in the Building.

         (iii) The proposed occupancy shall not increase the office cleaning
requirements, exceed the capacity of any base building system including, without
limitation, the electrical, heating, ventilation and air-conditions system, or
impose a material extra burden upon the Building's parking, equipment or
services.

         (iv) In the event any such Transfer will result in there being more
than two (2) tenants in addition to Tenant in the Premises, any additional
Transfer shall be subject to Landlord's reasonable determination that the number
of additional tenants shall not adversely affect other tenants' use of the
Building, the operation and maintenance of the Building, or otherwise detract
from the character of the Building as a comparable office and warehouse space.

                                       6

         (v) "INTENTIONALLY LEFT BLANK"

         (vi) No Event of Default, and no uncured default, shall have occurred
under this Lease, either at the time Landlord's consent to such Transfer is
requested, or at the commencement of the term of any proposed Transfer, or upon
the effective date of any such Transfer, and Tenant shall have complied with all
of the terms of this Article VII in connection with such Transfer.

         (vii) The proposed Transferee shall not be entitled, directly or
indirectly, to diplomatic or sovereign immunity and shall not be a government or
quasi government agency and shall be subject to the service of process in, and
under the jurisdiction of the courts of, the state in which the Building is
situated.

         (viii) The term of any proposed Transfer shall not be less than six (6)
months in length, except to the extent that the balance of the Lease Term at the
time of such proposed Transfer shall be less than six (6) months.

         (ix) In the event there have been more than two (2) previous
Transferees during the term of this Lease of any single portion of the space
proposed to be Transferred, any additional Transferee shall be subject to
Landlord's reasonable determination that the fluctuation in tenants shall not
adversely affect other tenants' use of the Building, the operation and
maintenance of the Building, or otherwise detract from the character of the
Building as comparable office and warehouse space.

         (x) Any Mortgagee whose consent is required shall have consented to
such Transfer.

         (xi) The proposed Transferee shall not have been specifically
identified in writing by Landlord's broker as a prospective tenant who remains
in active negotiations with Landlord within the ninety (90) days immediately
preceeding the initial request for the transfer.

         (b) No Transfer of this Lease may be effected by operation of law or
otherwise without Landlord's prior written consent as provided above. Any
Transfer, Landlord's consent thereto or Landlord's collection or acceptance of
rent from any Transferee shall not be construed as (i) an acceptance of such
Transferee as a tenant, (ii) a waiver or release of Tenant from liability
hereunder, or (iii) a waiver of Tenant's and any Transferee's obligation to
obtain Landlord's prior written consent to any subsequent Transfer. With respect
to any permitted assignment of this Lease, Tenant assigns to Landlord any sum
due from any Transferee as security for Tenant's performance of its obligations
pursuant to this Lease. Tenant authorizes each such Transferee to pay such sum
directly to Landlord if such Transferee receives written notice from Landlord
specifying that such rent shall be paid directly to Landlord. All restrictions
and obligations imposed pursuant to this Lease on Tenant shall be deemed to
extend to any Transferee, and Tenant shall cause any Transferee to comply with
all such restrictions and obligations. If the Lease Term or Tenant's right of
possession shall terminate prior to the stated expiration of the Lease Term,
then, at Landlord's option in its sole and absolute discretion, Landlord may
(but shall not be required to) succeed to the rights of Tenant under any or all
Transfers. Tenant shall not mortgage, pledge or encumber this Lease without
Landlord's prior written consent, which consent may be granted or withheld in
Landlord's sole and absolute discretion. Tenant shall pay the reasonable
expenses (including attorneys' fees) incurred by Landlord in connection with
Tenant's request for Landlord to give its consent to any Transfer or Mortgage.

     7.2 If Tenant is a partnership, then any dissolution of Tenant or a
withdrawal or change, whether voluntary, involuntary or by operation of law, of
partners owning a controlling interest in Tenant shall be deemed a Transfer of
this Lease subject to this Article. If Tenant is a corporation, then any
dissolution, merger, consolidation or other reorganization of Tenant, or any
sale or transfer of a controlling interest of its capital stock, shall be deemed
a Transfer of this Lease subject to this Article. If any Transfer is deemed to
have occurred pursuant to this Section, the Transferee shall be deemed to be
paying the greater of fair market rent or the actual rent to be paid by such
Transferee after any abatement or free rent period for purposes of determining
the excess rent referred to in Section 7.5 below.

     7.3 In order to request the consent of Landlord to a Transfer pursuant to
this Article, Tenant shall give Landlord written notice ("Tenant's Request
Notice") of the identity of the proposed Transferee and its business, all terms
of the proposed Transfer, the commencement date of the proposed Transfer, (the
"Proposed Transfer Commencement Date") and the area proposed to be assigned or
sublet (the "Proposed Transfer Space"). Tenant shall also transmit therewith the
most recent financial statement or other evidence of financial responsibility of
such Transferee, a certification executed by Tenant and such proposed Transferee
stating whether (and to what extent) any premium or other consideration is being
paid for the proposed Transfer, and all other information reasonably requested
by Landlord concerning such proposed Transferee. Tenant agrees to pay Landlord's
reasonable attorney's fees and costs incurred in connection with any proposed
assignment or subletting.

     7.4 Landlord shall have the right in its sole and absolute discretion to
terminate this Lease with respect to the Proposed Transfer Space by sending
Tenant written notice within thirty (30) days after Landlord's receipt of
Tenant's Request Notice. If the Proposed Transfer Space does not constitute the
entire Premises and Landlord elects to terminate this Lease with respect to the
Proposed Transfer Space, then: (a) Tenant shall tender the Proposed Transfer
Space to Landlord on the Proposed Transfer Commencement Date as if the Proposed
Transfer Commencement Date had been originally set forth in this Lease as the
expiration date of the Lease Term with respect to the Proposed Transfer Space;
and (b) as to all portions of the Premises other than the Proposed Transfer
Space, this Lease shall remain in full force and effect except that the
Permitted Parking Spaces, the additional rent payable pursuant to Article V, the
Parking Rent, and the Base Rent shall be reduced proportionately based on square
footage. Tenant shall pay all expenses of demising walls and other construction
required to permit the operation of the Proposed Transfer Space separate from
the balance of the Premises. If the Proposed Transfer Space constitutes the
entire Premises and Landlord elects to terminate this Lease, then: (1) Tenant
shall tender the Premises to Landlord on the Proposed Transfer Commencement
Date; and (2) the Lease Term shall terminate on the Proposed Transfer
Commencement Date.

     7.5 If the Transferee is to pay any amount in excess of the rent and other
charges due under this Lease, then, whether such excess be in the form of an
increased rental, lump sum payment, payment for the sale or lease of fixtures or
other leasehold improvements which were provided pursuant to the Work Agreement
or any other form (and if the applicable space does not constitute the entire
Premises, the existence of such excess shall be determined on a pro rata basis),
Tenant shall pay to Landlord any such excess (net of reasonable and customary
specific costs associated with the assignment or sublease, such as improvements
to the Premises and brokerage fees) upon such terms as shall be specified by
Landlord and in no event later than ten (10) days after Tenant receives (or is
deemed to have received) such excess. Landlord shall have the right to inspect
Tenant's books and records relating to any Transfer. Any Transfer shall be
effected on forms supplied or approved by Landlord.

                                  ARTICLE VIII
                             MAINTENANCE AND REPAIRS

     8.1 Tenant shall at its sole expense keep and maintain the Premises and all
Furnishings including, without limitation, any supplemental heating, ventilating
or air conditioning equipment and any other equipment located in the Premises in
clean, safe and sanitary condition and in good order and repair, shall suffer no
waste or injury thereto, and at the expiration or earlier termination of the
Lease Term, shall surrender the Premises in the same order and condition in
which they were on the Lease Commencement Date, ordinary wear and tear excepted.
Except as otherwise provided in Article XVII, all injury, breakage and damage to
the Premises and to any other part of the Building or the Land caused by any act
or omission of any invitee, agent, employee, subtenant, assignee, contractor,
client, family member, or licensee (collectively "Invitees") or Tenant, shall be
repaired by and at Tenant's expense, except that Landlord shall have the right
at Landlord's option to make any such repair and to charge Tenant for all
reasonable costs and expenses incurred in connection therewith. Tenant
responsible for janitorial and cleaning services for the premises.

     8.2 Subject to the provisions of Article V, Landlord shall provide
janitorial and cleaning services for the Building common areas consistent with a
comparable office and warehouse space in Stafford County, Virginia; maintenance
in good order, condition and repair of the parking facilities and all driveways
leading thereto, as well as all walkways, keeping the same free from any
unreasonable accumulation of snow; maintenance in a neat, safe and orderly
condition of all landscaped areas; maintenance in good order and repair
consistent with a comparable office and warehouse space in Stafford County,
Virginia of the Premises and the remainder of the Building and the Project
including but not limited to the exterior structure and systems, the walls, load
bearing elements, foundations, pipes and conduits, roof and common areas that
form a part of the Premises, parking areas, elevators, and the building standard
mechanical, electrical, HVAC and plumbing systems, provided, however, that
Tenant shall be responsible for those obligations set forth in Article 8.1
hereof.

                                   ARTICLE IX
                                   ALTERATIONS

     9.1 The original improvement of the Premises shall be accomplished by
Landlord in accordance with Exhibit B. Landlord is under no obligation to make
any alterations, decorations, additions, improvements or other changes in or to
the Premises or to the Building (collectively "Alterations") except as set forth
in Exhibit B or otherwise expressly provided in this Lease. As used in this
Lease, Alterations shall not include the hanging of pictures or other minor
improvements to the Premises such as repainting or recarpeting, provided that
such improvements are consistent with a comparable office and warehouse space.

                                       9
<PAGE>

     9.2 Tenant shall not make or permit anyone to make any Alteration without
Landlord's prior written consent, which consent shall not unreasonably be
withheld. Any Alteration made by Tenant shall be subject to the preceding
sentence and shall be made: (a) in a good, workmanlike, first-class and prompt
manner; (b) using new materials only; (c) by a contractor and in accordance with
plans and specifications and procedures approved in writing by Landlord; (d) in
accordance with all Laws and the requirements of any insurance company insuring
the Building and any Mortgagee; (e) after obtaining Landlord's written approval
of a workmen's compensation insurance and any other insurance policy required by
Landlord; and (f) after delivering to Landlord (i) an architect's certificate
that such Alteration will conform to all applicable Laws, (ii) a copy of all
necessary permits obtained from governmental authorities having jurisdiction,
and (iii) written, unconditional waivers of mechanics' and materialmen's liens
against the Premises and the Building from all proposed contractors,
subcontractors, laborers and material suppliers for all work and materials in
connection with such Alteration. If any lien (or a petition to establish a lien)
is filed in connection with any Alteration, then such lien (or petition) shall
be discharged (or proceedings shall have been filed for the purpose of
discharging any such lien) by Tenant at Tenant's expense within ten (10) days
thereafter by the payment thereof or filing of a bond acceptable to Landlord.
Landlord's consent to the making of any Alteration shall be deemed not to
constitute Landlord's consent to subject its interest in the Premises or the
Building to liens which may be filed in connection therewith. Tenant shall hire
Landlord (or its designee) to perform any Alteration, provided that the charge
to Tenant therefor is reasonable. Tenant shall furnish Landlord with an updated
set of "as-built" drawings reflecting any Alterations made by Tenant.

     9.3 If any Alteration is made without Landlord's prior written consent,
then Landlord shall have the right at Tenant's expense to remove and correct
such Alteration and restore the Premises and the Building to their condition
immediately prior thereto or to require Tenant to do the same. All Alterations
made by either party shall immediately become Landlord's property and shall
remain upon and be surrendered with the Premises at the expiration or earlier
termination of the Lease Term except that Tenant shall be required to remove all
Alterations (including any initial improvements to the Premises designated to be
removed on the initial plans) which Landlord designates in writing (at the time
such Alterations are approved) for removal. Notwithstanding the foregoing
sentence, if Tenant is not in default under this Lease, then Tenant shall have
the right to remove, prior to the expiration or earlier termination of the Lease
Term, all Movable Furnishings installed in the Premises solely at Tenant's
expense. "Movable Furnishings" shall be deemed to exclude any item which would
normally be removed from the Premises with the assistance of any tool or
machinery other than a dolly. If any such Furnishings are not removed by Tenant
prior to the expiration or earlier termination of the Lease Term, then the same
shall become Landlord's property and shall be surrendered with the Premises as a
part thereof; provided, however, that Landlord shall have the right to remove
from the Premises at Tenant's expense such Furnishings and any Alteration,
designated for removal by Landlord in writing, which Tenant fails to remove.
Landlord shall have the right to repair at Tenant's expense all damage to the
Premises or the Building caused by Tenant's removal of Furnishings or
Alterations designated by Landlord in writing for removal or to require Tenant
to do the same.

                                      SIGNS

     10.1 Landlord, at its expense, will list Tenant's name in the Building
directory, if any, and provide building standard signage on or near the primary
suite entry door. Tenant shall not paint, affix or otherwise display on any part
of the exterior or interior of the Building any other sign, advertisement or
notice. If any such item that has not been approved by Landlord is so displayed,
then Landlord shall have the right to remove such item at Tenant's expense or to
require Tenant to do the same.

                                   ARTICLE XI
                                SECURITY DEPOSIT

     11.1 Concurrently with Tenant's execution of this Lease, Tenant shall
deposit with Landlord the Security Deposit as security for the performance of
all of Tenant's obligations, covenants, conditions and agreements under this
Lease. Landlord shall not be required to pay interest on the Security Deposit or
to maintain the Security Deposit in a separate account. Upon any default by
Tenant, Landlord may use or apply all or part of the Security Deposit to
reimburse Landlord for any loss or expense incurred by reason of such default or
to pay any sum that Tenant fails to pay. Within three (3) business days after
written notice of Landlord's use of the Security Deposit, Tenant shall deposit
with Landlord cash in an amount sufficient to restore the Security Deposit to
its prior amount. Within approximately sixty (60) days after the later of (a)
the expiration or earlier termination of the Lease Term, or (b) Tenant's
vacating the Premises, Landlord shall return the Security Deposit less such
portion thereof as Landlord may have used to satisfy Tenant's obligations. If
Landlord transfers the Security Deposit to a transferee of the Building or
Landlord's interest therein, then such transferee (and not Landlord) shall be
liable for its return. Any Mortgagee shall not be liable for the return of the
Security Deposit unless such Mortgagee actually receives the Security Deposit.

                                   ARTICLE XII
                                  HOLDING OVER

     12.1 Tenant acknowledges that it is extremely important that Landlord have
substantial advance notice of the date on which Tenant will vacate the Premises,
because Landlord will (a) require an extensive period to locate a replacement
tenant, and (b) plan its entire leasing and renovation program for the Building
in reliance on its lease expiration dates. Tenant also acknowledges that if
Tenant fails to surrender the Premises at the expiration or earlier termination
of the Lease Term, then it will be conclusively presumed that the value to
Tenant of remaining in possession, and the loss that will be suffered by
Landlord as a result thereof, far exceed the Base Rent and additional rent that
would have been payable had the Lease Term continued during such holdover
period. Therefore, if Tenant does not immediately surrender the Premises upon
the expiration or earlier termination of the Lease Term, then the rent shall be
increased to equal the greater of (1) fair market rent for the Premises, or (2)
one and one-half (1.5) times the Base Rent, additional rent and other sums that
would have been payable pursuant to the provisions of this Lease if the Lease
Term had continued during such holdover period. Such rent shall be computed on a
monthly basis and shall be payable on the first day of such holdover period and
the first day of each calendar month thereafter during such holdover period
until the Premises have been vacated. Landlord's acceptance of such rent shall
not in any manner adversely affect Landlord's other rights and remedies,
including Landlord's right to evict Tenant and to recover damages.

                                       11
<PAGE>

Notwithstanding the foregoing, if Landlord consents in writing to Tenant holding
over at the expiration or earlier termination of the Lease Term (which consent
may be withdrawn by Landlord upon the giving of thirty (30) days prior notice to
Tenant), then the rent during such holdover period shall be the greater of (1)
fair market rent for the Premises, or (2) the Base Rent, additional rent and
other sums that would have been payable pursuant to the provisions of this Lease
if the Lease Term had continued during such holdover period.

                                  ARTICLE XIII
                                    INSURANCE

     13.1 Tenant shall not conduct or allow any activity or place or allow the
placement of any item in or about the Building which may (i) subject Landlord to
any increased risk of liability for injury to any person or property, (ii) cause
any increase in the insurance rates on any policies of insurance carried by
Landlord covering the Building, or cause insurance companies of good standing to
refuse to insure the Building in amounts reasonably satisfactory to Landlord,
(iii) result in the cancellation of any policy of insurance or the assertion of
any defense by the insurer to any claim under any policy of insurance maintained
by or for the benefit of Landlord, or (iv) violate any insurance requirement. If
any increase in the cost of such insurance is due to any such activity or item,
then (whether or not Landlord has consented to such activity or item) Tenant
shall pay the amount of such increase as additional rent within five (5) days
after Landlord's demand. The statement of any insurance company or insurance
rating organization (or other organization exercising similar functions in
connection with the prevention of fires or the correction of hazardous
conditions) that such an increase is due to any such activity or item shall be
conclusive evidence thereof.

     13.2 Tenant shall maintain throughout the Lease Term, with a company
licensed to do business in the jurisdiction in which the Building is located,
approved by Landlord and having a rating equal to or exceeding A:XI in Best's
Insurance Guide: (a) broad form comprehensive general liability insurance
(written on an occurrence basis and including contractual liability coverage
insuring the obligations assumed by Tenant pursuant to Section 15.2 and an
endorsement for personal injury); (b) all-risk property insurance; (c)
comprehensive automobile liability insurance (covering automobiles owned by
Tenant); (d) Broad Form Boiler and Machinery Insurance on all air conditioning
equipment, miscellaneous electrical apparatus, boilers and other pressure
vessels or systems, whether fired or unfired, installed by Tenant (or by
Landlord, at Tenant's expense) in or serving the Premises, either as part of the
extended coverage insurance mentioned in clause (b) of this Section or in
amounts set by Landlord, but in no event less than One Million Dollars
($1,000,000); (e) during the course of construction of any Alterations by Tenant
in the Premises and until completion thereof, Builder's Risk insurance on an
"all risk" basis (including collapse) on a completed value (non-reporting) form
for full replacement value, covering interests of Landlord and Tenant (and their
respective contractors and subcontractors) and any Mortgagee, in all work
incorporated in the Building and all materials and equipment in or about the
Premises; (f) Workers' Compensation Insurance, as required by law; and (g) such
other insurance in such amounts as Landlord may reasonably require from time to
time. All such insurance shall contain only reasonable "deductibles." The
minimum amounts of insurance required under this Section shall not be construed
to limit the extent of Tenant's liability under this Lease. Such liability

                                       12
<PAGE>

insurance shall be in minimum amounts typically carried by prudent tenants
engaged in similar operations, but in no event shall be in an amount less than
two million dollars ($2,000,000) combined single limit per occurrence for bodily
injury or death to any one person or any number of persons, and two million
dollars ($2,000,000) general aggregate for property damage. Such property
insurance shall be in an amount not less than that required to replace all work
done to the Premises in excess of that covered by the Work Agreement. Such
automobile liability insurance shall be in an amount not less than one million
dollars ($1,000,000) combined single limit per occurrence for bodily injury and
property damage and two million dollars ($2,000,000) in the aggregate. All
liability insurance shall name Landlord and any Mortgagee of Landlord as
additional insureds. All property insurance shall contain an endorsement that
such insurance shall remain in full force and effect notwithstanding that the
insured may have waived its claims against any person prior to the occurrence of
a loss, and provide that the insurer waives all right of recovery by way of
subrogation against Landlord, its officers, agents and employees. All of
Tenant's insurance shall contain an endorsement prohibiting modification,
expiration or cancellation (1) as to the interests of Landlord and any Mortgagee
of Landlord by reason of any act or omission of Tenant, and (2) without the
insurer's giving Landlord thirty (30) days' prior written notice of such action.
Landlord reserves the right from time to time to reasonably require Tenant to
obtain higher minimum amounts of insurance. Tenant shall deliver a certificate
of insurance and receipts evidencing payment of the premium for all required
insurance policies (and, upon request, copies of all required insurance
policies, including endorsements and declarations) to Landlord on or before the
Lease Commencement Date and at least annually thereafter, no less than thirty
(30) days prior to the earliest expiration date on such certificate.

     13.3 Landlord shall keep the Building insured against loss or damage by
fire and such other risks as are now or may be customarily covered with respect
to buildings and improvements similar in construction, general location, use,
occupancy and design. Landlord shall also maintain for its benefit and for the
benefit of Tenant and other tenants of the Building general public liability
insurance against claims for personal injury, death or property damage occurring
upon, in or about the Project, such insurance to afford protection to Landlord
and its managing agent, if applicable, of a combined single limit of Two Million
and No/100 Dollars ($2,000,000) in respect to the injury, death or property
damage arising out of any accident or occurrence. Landlord agrees to include in
its general public liability insurance policy the contractual liability coverage
insuring Landlord indemnification obligations provided for herein. Any such
coverage shall be deemed primary to any liability coverage secured by Tenant.

     13.4 These insurance provisions shall in no way limit or modify any of the
obligations of Landlord or Tenant under any provisions of this Lease. The
parties agree that such policies of insurance shall permit releases of liability
as provided herein and/or waiver of subrogation clauses in favor of each party
and each waives, releases and discharges the other from all claims or demands
whatsoever which the other may have or acquire under this Lease to the extent of
insurance coverage for such event or occurrence. Insurance premiums paid for
insurance coverage required under this Article XIII by Landlord shall be a
portion of the Operating Expenses described in Article V hereof.

     14.1 Landlord shall furnish to the Premises air-conditioning and heating
during the seasons they are required consistent with a comparable office and
warehouse space in Stafford County, Virginia. Landlord shall provide maintenance
services as provided in Article VIII; electricity (24 hours a day/7 days a
week); water (24 hours a day/7 days a week); elevator service (24 hours a day/7
days a week. The normal hours of operation of the Building will be 8:00 a.m. to
6:00 p.m. on Monday through Friday (except Holidays) and 9:00 a.m. to 1:00 p.m.
on Saturday (except Holidays) and such other hours, if any, as Landlord
determines. Landlord agrees to provide Tenant with advance notice of any
scheduled utility outages if Landlord has advance notice of such outages. If
Tenant requires air-conditioning or heat beyond the normal operating hours, then
Landlord will furnish the same at Tenant's expense in accordance with Landlord's
then-current schedule, provided Tenant gives Landlord sufficient advance notice
(not less than 24 hours) of such requirement. Subject to the provisions of this
Lease, Tenant shall have access by electronic card-key system or key to the
Building twenty-four (24) hours a day, seven (7) days a week, three hundred
sixty-five (365) days a year.

                              LIABILITY OF LANDLORD

     15.1 Landlord, its members, employees, agents and mortgagees, except for
gross negligence or willful misconduct, shall not be liable to Tenant, any
invitee or any other person or entity for any damage (including indirect and
consequential damage), injury, loss or claim (including claims for the
interruption of or loss to business) based on or arising out of any cause
whatsoever (except as otherwise provided in this Section), including without
limitation the following: repair to any portion of the Premises or the Building;
interruption in the use of the Premises or any equipment therein; any accident
or damage resulting from any use or operation (by Landlord, Tenant or any other
person or entity) of elevators or heating, cooling, electrical, sewerage or
plumbing equipment or apparatus; termination of this Lease by reason of damage
to the Premises or the Building; fire, robbery, theft, vandalism, mysterious
disappearance or any other casualty; actions of any other tenant of the Building
or of any other person or entity; failure or inability to furnish any service or
utility specified in this lease; and leakage in any part of the Premises or the
Building from water, rain, ice or snow that may leak into, or flow from, any
part of the Premises or the Building, or from drains, pipes or plumbing fixtures
in the Premises or the Building. If any condition exists that may be the basis
of a claim of constructive eviction, then Tenant shall give Landlord written
notice thereof and a reasonable opportunity to correct such condition, and in
the interim Tenant shall not claim that it has been constructively evicted or is
entitled to a rent abatement. Any property placed by Tenant or Invitees in or
about the Premises or the Building shall be at the sole risk of Tenant, and
Landlord shall not in any manner be responsible therefor. If any employee of
Landlord receives any package or article delivered for Tenant, then such
employee shall be acting as Tenant's agent for such purpose and not as
Landlord's agent. For purposes of this Article, the term "Building" shall be
deemed to include the Land. Notwithstanding the foregoing provisions of this
Section, Landlord shall not be released from liability to Tenant for any
physical injury to any natural person or other damage or loss caused by, or
resulting from, Landlord's gross negligence or intentional acts.

     15.2 Unless arising or resulting from Landlord's gross negligence or
willful misconduct, Tenant shall reimburse Landlord for, and shall indemnify,
defend upon request and hold Landlord, its employees and agents harmless from
and against, all costs, damages, claims, liabilities, expenses (including
attorneys' fees), losses and court costs suffered by or claimed against

                                       14
<PAGE>

Landlord, directly or indirectly, based on or arising out of, in whole or in
part: (a) use and occupancy of the Premises or the business conducted therein;
(b) any act or omission of Tenant or any Invitee; (c) any breach of Tenant's
obligations under this Lease, including failure to surrender the Premises upon
the expiration or earlier termination of the Lease Term, (d) any entry by Tenant
or any Invitee in or upon the Building prior to the Lease Commencement Date; or
(e) the breach of any representation or warranty made by Tenant in this Lease.

     15.3 If any landlord hereunder transfers the Building or such landlord's
interest therein, then such landlord shall not be liable for any obligation or
liability based on or arising out of any event or condition occurring after such
transfer. Within five (5) days after request, Tenant shall attorn to such
transferee and execute, acknowledge and deliver any document submitted to Tenant
confirming such attornment (at no cost to Tenant).

     15.4 Tenant shall not have the right to offset or deduct the amount
allegedly owed to Tenant pursuant to any claim against Landlord from any rent or
other sum payable to Landlord. Tenant's sole remedy for recovering upon such
claim shall be to institute an independent action against Landlord.

     15.5 If Tenant or any Invitee is awarded a money judgment against Landlord,
then recourse for satisfaction of such judgment shall be limited to execution
against Landlord's estate and interest in the Building. No other asset of
Landlord, any member, manager, partner, director or officer of Landlord
(collectively "Officer") or any other person or entity shall be available to
satisfy or be subject to such judgment, nor shall any Officer or other person or
entity have personal liability for satisfaction of any claim or judgment against
Landlord or any Officer.

                                   ARTICLE XVI
                                      RULES

     16.1 Tenant and Invitees shall observe the rules specified in Exhibit D and
any other rule not inconsistent with this Lease, of which notice is given, that
Landlord may promulgate for the operation or maintenance of the Building.
Landlord shall have no duty to enforce such rules or any provision of any other
lease against any other tenant; provided that Landlord shall not enforce the
rules against Tenant in a way that discriminates unfairly against Tenant.

                                  ARTICLE XVII
                               DAMAGE TO BUILDING

     17.1 If the Premises or the Building are totally or partially damaged by
fire or other casualty, and (a) Landlord's insurance is insufficient (through no
fault of Landlord and provided that Landlord has maintained insurance on the
Building in accordance with Article 13.3 hereof) to pay the full cost of the
repair and restoration to be performed by Landlord, (b) any Mortgagee fails or
refuses to make such insurance proceeds available for such repair and
restoration, (c) zoning or other applicable Laws do not permit such repair and
restoration, (d) the cost of repair and restoration exceeds twenty-five percent
(25%) of the replacement value of the Building, or (e) in Landlord's judgment
the period needed for effecting a satisfactory settlement with any insurance
company involved, removing debris, preparing plans, obtaining all required
governmental permits and other approvals and completing such repair and
restoration will exceed two hundred seventy (270) days after the occurrence of
such damage, then Landlord shall have the right, at its sole option, to

                                       15
<PAGE>

terminate this Lease by giving written notice of termination within forty-five
(45) days after the occurrence of such damage, or, if later, within ten (10)
days after Landlord last receives notice of the existence of any of the
circumstances in clauses (a) through (e) above. Landlord shall have no liability
to Tenant in the event Landlord's estimate of the time frame for the
circumstances in clause (e) above proves inaccurate. If the Premises are totally
or partially damaged by fire or other casualty that renders the Premises totally
or partially inaccessible or unusable, and the conditions in clause (e) above
exist with respect to the Premises, then Tenant shall have the right, at
Tenant's option, to terminate this Lease by giving written notice of termination
within forty-five (45) days after the occurrence of such damage, or, if earlier,
within ten (10) days after Landlord notifies Tenant that Landlord intends to
proceed with repair and restoration as required by this Article. If this Lease
is terminated pursuant to this Article, then rent shall be apportioned (and
rebated to Tenant if applicable) (based on the portion of the Premises which is
usable after such damage) and paid to the date of termination.

     17.2 If this Lease is not terminated as a result of such damage, then,
after collecting the insurance proceeds attributable to such damage (including
the proceeds of any insurance maintained by Tenant with respect to work in
excess of the work performed pursuant to the Work Agreement, which proceeds
shall be paid to Landlord), Landlord shall diligently repair and restore the
Premises to substantially the same condition they were in prior to such damage;
provided, however, that Landlord shall not be required to repair or restore any
of Tenant's Furnishings or personal property. Landlord shall bear the expenses
of such repair and restoration of the Premises and the Building; provided,
however, that: (a) if such damage or destruction was caused by the act or
omission of Tenant or any Invitee, then Tenant shall pay the amount by which
such expenses exceed the insurance proceeds, if any, actually received by
Landlord on account of such damage and the amount of any deductible; and (b)
Tenant shall pay the amount by which the cost of restoring any work in excess of
the work performed pursuant to the Work Agreement exceeds the insurance
proceeds, if any, received with respect thereto. If this Lease is not terminated
as a result of such damage, then commencing on the date of the occurrence of
such casualty until such repair and restoration of the Premises are
substantially complete, Tenant shall be required to pay the Base Rent and
additional rent only for the portion of the Premises that is usable for Tenant
to reasonably conduct its business while such repair and restoration are being
made; provided, however, that: (1) if such damage was caused by the act or
omission of Tenant or any Invitee, then Tenant shall not be entitled to any such
rent reduction; and (2) if a delay in the substantial completion of such repair
and restoration shall occur as a result of any cause of the kind described in
the Work Agreement as a Tenant Delay, including any failure by Tenant to provide
Landlord with plans and specifications for such repair or restoration within
fifteen (15) days of Landlord's request or any delay by Tenant in giving
authorizations, approvals or substitutions necessary for completion of the
repair or restoration, then Tenant shall not be entitled to any rent reduction
for any period in excess of the period which would be necessary regardless of
the aforementioned delays to restore the Premises to the Tenant Cost Allowance
condition.

                                  ARTICLE XVIII
                                  CONDEMNATION

     18.1 If one-third or more of the area of the Premises or occupancy thereof
shall be taken or condemned by any governmental or quasi-governmental authority
for any public or quasi-public use or purpose or sold under threat of such a
taking or condemnation (collectively, "Condemned" or "Condemnation"), then this
Lease shall terminate on the date title vests in such authority and rent shall
be apportioned as of such date. If less than one-third of the Premises or

                                       16
<PAGE>

occupancy thereof is Condemned and Tenant is thereafter able to reasonably
conduct its business, then this Lease shall continue in full force and effect as
to the part of the Premises not Condemned, except that as of the date title
vests in such authority Tenant shall not be required to pay the Base Rent and
additional rent with respect to the part of the Premises Condemned. If any
Condemnation reduces the number of parking spaces available to the Building,
then the number of Permitted Parking Spaces shall be reduced proportionately. If
there is a Condemnation of the Land or the Building for which the award, damages
and other compensation can reasonably be expected to exceed twenty-five percent
(25%) of the replacement value of the Land or Building, then regardless of
whether the Premises are affected, Landlord shall have the right to terminate
this Lease as of the date title vests in such authority by written notice to
Tenant within forty-five (45) days of the date title vests in such authority.

     18.2 All awards, damages and other compensation paid by such authority on
account of such Condemnation shall belong to Landlord, and Tenant assigns to
Landlord all rights to such awards, damages and compensation. Tenant shall not
make any claim against Landlord or the authority for any portion of such award,
damages or compensation attributable to damage to the Premises, value of the
unexpired portion of the Lease Term, loss of profits or goodwill, leasehold
improvements or severance damages. Nothing contained herein, however, shall
prevent Tenant from pursuing a separate claim against the authority for the
value of Furnishings installed in the Premises at Tenant's expense and for
relocation expenses; provided that such claim shall in no way diminish the
amounts payable to Landlord in connection with such Condemnation.

                                   ARTICLE XIX
                                     DEFAULT

     19.1 An "Event of Default" is: (a) Tenant's failure to pay any Base Rent,
additional rent or other sum within five (5) days of the date on which such sum
is due; (b) Tenant's failure to perform or observe any other covenant or
condition, which failure continues for thirty (30) days after written notice of
such failure is sent by Landlord to Tenant; (c) Tenant's failure to occupy
continuously the Premises (except as provided for in Article VII); (d) an Event
of Bankruptcy as specified in Article XX; (e) Tenant's dissolution or
liquidation; or (f) any material breach of representation or warranty by Tenant.

     19.2 This Lease is entered into on the express condition that if there
shall be an Event of Default, including an Event of Default prior to the Lease
Commencement Date, then the provisions of this Section shall apply. Landlord
shall have the right, at its sole option, to terminate this Lease. In addition,
with or without terminating this Lease, Landlord may re-enter, terminate
Tenant's right of possession and take possession of the Premises pursuant to
this Article XIX or under applicable laws, or by such other proceedings,
including re-entry and possession, as may be applicable. The provisions of this
Article shall operate as a notice to quit, any other notice to quit or of
Landlord's intention to re-enter the Premises being expressly waived. If
Landlord elects to terminate this Lease and/or elects to terminate Tenant's
right of possession, then all of Landlord's obligations as set forth in this
Lease shall cease. Landlord may relet the Premises or any part thereof, alone or
together with other premises, for such term(s) (which may extend beyond the date
on which the Lease Term would have expired but for Tenant's default) and on such
terms and conditions (which may include reasonable concessions and alterations
of the Premises) as Landlord, in its sole discretion, may determine, but

                                       17
<PAGE>

Landlord shall not be liable for, nor shall Tenant's obligations be diminished
by reason of, Landlord's failure to relet the Premises or collect any rent due
upon such reletting. Whether or not this Lease is terminated, Tenant
nevertheless shall remain liable for the Base Rent, additional rent and any
other sums or damages which may be due or sustained prior to the later of
termination of this Lease or Landlord's recovery of possession of the Premises,
and all costs, fees and expenses (including without limitation reasonable
attorney's fees, brokerage fees and expenses incurred in placing the Premises in
first-class rentable condition) incurred by Landlord in pursuit of its remedies
and in renting the Premises to others from time to time. Tenant shall also be
liable for additional damages which at Landlord's election shall be either
Monthly Damages or Present Value Damages. "Monthly Damages" shall be an amount
equal to the Base Rent and additional rent which would have become due during
the remainder of the Lease Term, less the amount of rental, if any, which
Landlord receives during such period from others to whom the Premises may be
rented (other than any additional rent payable as a result of any failure of
such other person to perform any of it obligations), which damages shall be
computed and payable in monthly installments, in advance, on the first day of
each calendar month following Tenant's default and continuing until the date on
which the Lease Term would have expired but for Tenant's default. Separate suits
may be brought to collect any such Monthly Damages for any month(s), and such
suits shall not in any manner prejudice Landlord's right to collect any such
damages for any subsequent month(s), or Landlord may defer any such suit until
after the expiration of the Lease Term, in which event such suit shall be deemed
not to have accrued until the expiration of the Lease Term. "Present Value
Damages" shall be an amount equal to the present value (as of the date of
Tenant's default) of the Base Rent and additional rent which would have become
due through the date on which the Lease Term would have expired but for Tenant's
default, which damages shall be payable to Landlord in a lump sum on demand. For
purpose of this Section, present value shall be computed by discounting at a
rate equal to one (1) whole percentage point above the discount rate then in
effect at the Federal Reserve Bank with jurisdiction over banks in the area in
which the Building is located. Tenant waives any right of redemption, re-entry
or restoration of the operation of this Lease under any present of future law,
including any such right which Tenant would otherwise have if Tenant shall be
dispossessed for any cause. Landlord agrees to make reasonable efforts to
mitigate its damages hereunder.

     19.3 Landlord shall have the right to terminate any renewal or expansion
right contained in this Lease, and to grant or withhold any consent or approval
pursuant to this Lease in its sole and absolute discretion, if an Event of
Default has occurred. If this Lease requires Landlord to be reasonable in giving
any prior written consent or approval of an action by Tenant, Landlord
nevertheless shall not be required to be reasonable in approving the action of
Tenant if Tenant took the action without first seeking Landlord's prior written
consent pursuant to this Lease. Landlord shall have no obligation to refund to
Tenant or to credit to Tenant against any other amounts or installments coming
due to Landlord hereunder any amount otherwise owed or creditable by Landlord to
Tenant pursuant to the terms of this Lease if an Event of Default has occurred
(except that as a result thereof Landlord shall not be entitled to receive more
than 100% of what it is entitled to receive from Tenant under this Lease). The
provisions of this Section shall apply notwithstanding anything to the contrary
in this Lease, and whether or not this Lease and/or Tenant's right of possession
is terminated as a result of Tenant's default.

                                       18
<PAGE>

     19.4 After the occurrence of an Event of Default, any abatement of Base
Rent and additional rent payable for Operating Charges for periods subsequent to
the Event of Default shall be null and void. Landlord's right to receive the
Base Rent and additional rent for such future abatement period shall be in
addition to any other remedies available to Landlord as a result of such Event
of Default, termination or re-entry.

     19.5 Landlord's rights and remedies set forth in this Lease are cumulative
and in addition to Landlord's other rights and remedies at law or in equity.
Landlord's exercise of any such right or remedy shall not prevent the concurrent
or subsequent exercise of any other right or remedy. Landlord's delay or failure
to exercise or enforce any of Landlord's rights or remedies or Tenant's
obligations shall not constitute a waiver of any such rights, remedies or
obligations. Landlord shall not be deemed to have waived any default unless such
waiver expressly is set forth in an instrument signed by Landlord. Any such
waiver shall not be construed as a waiver of any covenant or condition except as
to the specific circumstances described in such waiver. Neither Tenant's payment
of an amount less than a sum due nor Tenant's endorsement or statement on any
check or letter accompanying such payment shall be deemed an accord and
satisfaction. Notwithstanding any request or designation by Tenant, Landlord may
apply any payment received from Tenant to any payment then due. Landlord may
accept the same without prejudice to Landlord's right to recover the balance of
such sum or to pursue other remedies. Re-entry and acceptance of keys shall not
be considered an acceptance of a surrender of this Lease.

     19.6 If more than one natural person and/or entity shall constitute Tenant
or if Tenant is a general partnership or other entity, the partners or members
of which are subject to personal liability, then the liability of each such
person, entity, partner or member shall be joint and several. If Tenant is a
partnership, without limiting any other proper means for service of process upon
Tenant or its partners, Tenant represents and warrants to Landlord that each
General Partner has irrevocably appointed the person to whom notices to Tenant
under this Lease are to be addressed as its agent for service of process in all
matters relating to this Lease. Tenant represents and warrants to Landlord that
neither Tenant, nor any Guarantor, nor any General Partner, is entitled,
directly or indirectly, to diplomatic or sovereign immunity.

     19.7 If Tenant fails to make any payment to any third party or to do any
act herein required to be made or done by Tenant in relation to this Lease, the
Landlord may, but shall not be required to, make such payment or do such act.
Landlord's taking such action shall not be considered a cure of such failure by
Tenant or prevent Landlord from pursuing any remedy it is otherwise entitled to
in connection with such failure. If Landlord elects to make such payment or do
such act, then all expenses incurred, plus interest thereon at the Default Rate
from the date incurred to the date of payment thereof by Tenant, shall
constitute additional rent. The "Default Rate" shall equal the rate per annum
which is the greater of eighteen percent (18%) or three (3) whole percentage
points above the Wall Street Journal Prime Rate or such replacement rate as
Landlord may designate if said prime rate is not available.

     19.8 If Tenant fails to make any payment of the Base Rent, additional rent
or any other sum payable to Landlord on or before five (5) days after the date
such payment is due and payable, then Tenant shall pay a late charge of five
percent (5%) of the amount of such payment. In addition, such payment shall bear
interest at the Default Rate from the date such payment was due to the date of
payment.

                                   BANKRUPTCY

     20.1 An "Event of Bankruptcy" is: the occurrence, with respect to Tenant,
any guarantor or surety of this Lease ("Guarantor"), or any general partner in
Tenant (a "General Partner") of any of the following: (a) any such person's
becoming insolvent, as that term is defined in Title 11 of the United States
Code (the "Bankruptcy Code"), or under the insolvency laws of any state (the
"Insolvency Laws"); (b) appointment of a receiver or custodian for any property
of any such person, or the institution of a foreclosure or attachment action
upon any property of any such person; (c) filing of a voluntary petition by any
such person under the provisions of the Bankruptcy Code or Insolvency Laws; (d)
filing of an involuntary petition against any such person as the subject debtor
under the Bankruptcy Code or Insolvency Laws, which either (1) is not dismissed
within sixty (60) days after filing, or (2) results in the issuance of an order
for relief against the debtor; or (e) any such person's making or consenting to
an assignment for the benefit of creditors or a composition of creditors.

     20.2 Upon occurrence of an Event of Bankruptcy, Landlord shall have all
rights and remedies available pursuant to Article XIX; provided, however, that
while a case (the "Case") in which Tenant is the subject debtor under the
Bankruptcy Code is pending, Landlord's right to terminate this Lease shall be
subject, to the extent required by the Bankruptcy Code, to any rights of Tenant
or its trustee in bankruptcy (collectively, "Trustee") to assume or assign this
Lease pursuant to the Bankruptcy Code. Trustee shall not have the right to
assume or assign this Lease unless Trustee promptly: (a) cures all defaults
under this Lease; (b) compensates Landlord for damages incurred as a result of
such defaults; (c) provides adequate assurance of future performance on the part
of Tenant or Tenant's assignee; (d) complies with the other requirements of this
Article; and (e) complies with all other requirements of the Bankruptcy Code. If
Trustee fails to assume or assign this Lease in accordance with the requirements
of the Bankruptcy Code within sixty (60) days after the initiation of the Case,
then Trustee shall be deemed to have rejected this Lease. Adequate assurance of
future performance shall require that the following minimum criteria be met: (1)
Tenant's gross receipts in the ordinary course of business during the thirty
(30) days preceding the Case must be greater than ten (10) times the next
monthly installment of the Base Rent and additional rent; (2) both the average
and median of Tenant's monthly gross receipts in the ordinary course of business
during the seven (7) months preceding the Case must be greater than ten (10)
times the next monthly installment of the Base Rent and additional rent; (3)
Trustee must pay its estimated pro-rata share of the cost of all services
performed or provided by Landlord (whether directly or through agents or
contractors and whether or not previously included as part of the Base Rent) in
advance of the performance or provision of such services; (4) Trustee must agree
that Tenant's business shall be conducted in a first-class manner, and that no
liquidating sale, auction or other non-first-class business operation shall be
conducted in the Premises; (5) Trustee must agree that the Use of the Premises
as stated in this Lease shall remain unchanged and that no prohibited use shall
be permitted; (6) Trustee must agree that the assumption or assignment of this
Lease shall not violate or affect the rights of other tenants in the Building
and the Project; (7) Trustee must pay at the time the next monthly installment
of the Base Rent is due, in addition to such installment, an amount equal to the
monthly installments of the Base Rent and additional rent due for the next six
(6) months thereafter, such amount to be held as a security deposit; (8) Trustee
must agree to pay, at any time Landlord draws on such security deposit, the
amount necessary to restore such security deposit to its original amount; and
(9) all assurances of future performance specified in the Bankruptcy Code must
be provided. If Trustee shall propose to assume and assign this Lease to any

                                       20
<PAGE>

person who shall have made a bona fide offer to accept an assignment of this
Lease on terms acceptable to Trustee, then notice of such proposed assignment
shall be given to Landlord by Trustee no later than twenty (20) days after
receipt by Trustee of such offer, but in any event no later than ten (10) days
prior to the date that Trustee shall make application to the court of competent
jurisdiction for approval to assume this Lease and enter into such assignment,
and Landlord shall thereupon have the option, to be exercised by notice to
Trustee given at any time prior to the date of such application, to accept an
assignment of this Lease upon the same terms and conditions and for the same
consideration, if any, as the offer made by such person, less any brokerage
commissions which may be payable out of the consideration to be paid by such
person for the assignment of this Lease.

                                   ARTICLE XXI
                                  SUBORDINATION

     21.1 A "Mortgage" is any of the following now or hereafter in effect: any
mortgage, deed of trust, financing statement or similar security or financing
instrument securing any existing or future debt or obligation and encumbering or
affecting the Building; any master lease, ground lease or other underlying lease
or sublease under which Landlord is lessee or sublessee of the Building; and all
renewals, extensions, modifications, recastings or refinancings of any such
agreement or instrument. A "Mortgagee" is the holder or other party secured by,
or lessor under, any Mortgage and shall include trustees and successors and
assigns of such party whether immediate or remote, the purchaser of any Mortgage
whether at foreclosure or otherwise, and the successors, assigns and Mortgagees
of such purchaser whether immediate or remote. A "Foreclosure" is any
foreclosure, trustee's sale, deed-in-lieu of foreclosure, termination or other
enforcement. The provisions of this Article shall be effective without any
further document signed by Tenant; however, in confirmation of the provisions of
this Article, Tenant shall at Landlord's request promptly execute any requisite
or appropriate documents. Tenant appoints Landlord as Tenant's attorney-in-fact
to execute any such documents for Tenant.

     21.2 This Lease is subject and subordinate to the lien, operation and
effect of all Mortgages and any and all advances made or hereafter made under
each such Mortgage, except that if and to the extent specifically elected by any
Mortgagee in writing, at its sole option, this Lease shall be deemed superior to
such Mortgagee's Mortgage and any Mortgage which is subordinate to such
Mortgage, to the extent necessary to prevent any Foreclosure of such Mortgage
and/or Mortgages from terminating or affecting this Lease and Tenant's rights
hereunder, but such superiority shall not limit the ability of any Mortgagee to
exercise the other rights granted in its Mortgage, including but not limited to
the right to direct the application of insurance or condemnation proceeds. Such
election by a Mortgagee may be made in its Mortgage, in an advertisement of a
Foreclosure sale, or in a separate document executed before, or within a
reasonable time after, a Foreclosure. Tenant waives the provisions of any
statute or rule of law now or hereafter in effect which may give or purport to
give Tenant any right to terminate or otherwise adversely affect this Lease or
Tenant's obligations in the event any Foreclosure is prosecuted or completed or
in the event the Land, the Building or Landlord's interest therein is sold at a
Foreclosure. If this Lease is not terminated or extinguished upon such
Foreclosure or by the purchaser or successor ("Successor") following such
Foreclosure, then Tenant shall attorn to such Successor and shall recognize such
Successor as the landlord under this Lease. Upon such attornment such Successor
shall not be: (a) bound by any payment of the Base Rent or additional rent more
than one (1) month in advance; (b) bound by any amendment of this Lease made

                                       21
<PAGE>

without the written consent of the Mortgagee under each Mortgage existing as of
the date of such amendment; (c) liable for any breach, act or omission of any
prior landlord; (d) subject to any offsets, defenses or counterclaims which
Tenant might have against any prior landlord; (e) obligated to perform any work
for Tenant or the Premises; or (f) liable for the return of any security deposit
not actually received by such Successor. Any liability of the Mortgagee or
Successor hereunder shall exist only during the time such Mortgagee or Successor
is the owner of the Land, Building or the Project and shall be subject to any
other limitations of liability under this Lease.

     21.3 If any lender or prospective lender providing financing secured by the
Building requires as a condition of such financing that modifications to this
Lease be obtained, and provided that such modifications (a) are reasonable, (b)
do not affect in a material manner Tenant's use of the Premises as herein
permitted, and (c) do not increase the rent and other sums to be paid by Tenant,
then Tenant shall execute, acknowledge and deliver to Landlord (at no cost to
Tenant) an amendment to this Lease incorporating such modifications within five
(5) days after receipt of such amendment from landlord.

     21.4 Tenant shall be entitled to rely on any notice which Tenant receives
from any Mortgagee stating that such Mortgagee is exercising its rights under
its Mortgage and is thereafter entitled to receive all amounts thereafter due
under this Lease; provided that Tenant has first received from such Mortgagee
written notice of the existence of such Mortgage, together with a copy of the
relevant provision of the applicable instrument and a copy of any and all
notices to Landlord pursuant to which said Mortgagee is exercising said right to
receive the amounts thereafter due hereunder.

                                  ARTICLE XXII
                                 QUIET ENJOYMENT

     22.1 Landlord covenants that if Tenant shall perform timely all of its

                               GENERAL PROVISIONS

     23.1 Tenant acknowledges that neither Landlord nor any broker, agent or
employee of Landlord has made any representation or promise with respect to the
Premises or the Building except as expressly set forth herein, and no right is

financial statements of Tenant, each Guarantor (if any) and each General Partner
(if any), together with such additional information regarding the financial or
other condition of such persons as Landlord may request. The financial
statements for each such person shall be audited or reviewed to the most
rigorous level or review of any financial statements previously delivered to
Landlord for such person. Tenant represents and warrants to Landlord that all
financial statements and information previously or in the future delivered to
Landlord regarding Tenant, any Guarantor and any General Partner shall be true,
correct and complete. Tenant represents and warrants to Landlord that there has

this Lease. Any statements delivered pursuant to this Section may be relied upon
by any owner of the Building or the Land, any prospective purchaser of the
Building or the Land, any lender or prospective lender, or any other person or
entity. Tenant acknowledges that time is of the essence to the delivery of such

in any action, claim or counterclaim brought in connection with any matter
arising out of or in any way connected with this Lease, the landlord-tenant
relationship, Tenant's use or occupancy of the Premises or any claim of injury
or damage. Tenant consents to service of process and any pleading relating to
any such action at the Premises; provided, however, that nothing herein shall be
construed as requiring such service at the Premises. Landlord, Tenant, all

fullest extent permitted by law. If any provision or its application to any
person or circumstance shall to any extent be invalid or unenforceable, then
such provision shall be deemed to be replaced by the valid and enforceable
provision most substantively similar thereto, and the remainder of this Lease
and the application of such provision to other persons or circumstances shall

actually or allegedly wrongfully withholding or delaying any consent under or in
connection with this Lease. Tenant's sole remedy for any wrongfully withheld or
delayed consent shall be a proceeding for specific performance, or injunction or
declaratory judgment. In no event shall Tenant be entitled to any other rights
or remedies arising from any such withholding or delaying of consent.

     23.16 Landlord reserves the right to make reasonable changes to the plans
and specifications for the Building without Tenant's consent, provided such
changes do not alter the character of the Building as a comparable office and
warehouse space and that such changes be done in a commercially reasonable
manner.

     23.17 Except as otherwise provided in this Lease, any additional rent or

incurred by Landlord for which Tenant is liable, shall be considered additional
rent payable pursuant to this Lease and paid by Tenant no later than ten (10)
days after the date Landlord notifies Tenant in writing of the amount thereof.
If Tenant wishes to object to any statement rendered by Landlord setting forth
the amount of any additional rent, Tenant shall give Landlord written notice,
specifying in reasonable detail the grounds for Tenant's objection, within ten
(10) days after the statement is rendered to Tenant; provided that such
objection shall not entitle Tenant to reduce or delay paying any additional
rent. Tenant shall be deemed to have waived any such objection if Tenant does
not give Landlord the written notice of objection as and when described above.

     23.18 The rentable area of the Building and the Premises shall be
determined by the Landlord in accordance with the BOMA Standard Method of

termination.

performing any obligation due to fire, act of God, governmental act or failure
to act, labor dispute, inability to procure materials or any cause beyond their

obligations hereunder) shall be excused for the period of such delay or
prevention and extended for a period equal to the period of such delay or
