================================================================================
This Agreement ("Agreement"), is made by and between MCI WORLDCOM
Communications, Inc. ("WorldCom"), on behalf of itself and its affiliates and
successors and CROSSWALK.COM ("Customer").

1.   SERVICE.
1.1  WorldCom will provide Customer use of the hardware and software, and
     furnish to Customer the support, network connectivity and physical access
     (collectively, the "Services") set forth in Service Order Form(s) ("Service
     Order") attached to this Agreement and incorporated herein by this
     reference. Each Service Order identifies the physical location ("Facility")
     of the equipment storage space to be made available to Customer (the
     "Space"), for installation of Customers equipment (the "Equipment").
     WorldCom reserves the right to modify any Service from time to time;
     provided that Customer may terminate a Service without any additional
     changes within 30 days following implementation of any change to a Service
     that has a material adverse affect on the functionality of that Service if
     WorldCom fails to correct the adverse effect in the 10 days following
     Customer's written notification to WorldCom of such effect.
1.2  Customer, and not WorldCom, has sole and exclusive control over the content
     residing on Customer's server(s) (the "Customer Content"). Customer
     acknowledges and WorldCom agrees that in the provision of the Services
     hereunder WorldCom is not provided, either directly or indirectly, and will
     not seek access to the Customer Content that would allow WorldCom to
     exercise any control over the Customer Content.
1.3  Customer shall use its best efforts to promptly and thoroughly respond to
     any notices forwarded to Customer by WorldCom, including, but not limited
     to notices that the Customer Content violates the Digital Millennium
     Copyright Act (the "DMCA").

2.   CONTRACTORS. WorldCom, its affiliates or subcontractors may perform some or
     all of WorldCom's duties and/or obligations hereunder.

3.   PAYMENT.
3.1  GENERALLY. Customer agrees to the charges for the Services as set forth on
     the Service Order. Monthly Charges shall begin accruing on the date that
     WorldCom is prepared to provide Customer with Internet Connectivity to the
     Equipment (the "Service Activation Date") which date shall also indicate
     WorldCom's acceptance of the applicable Service Order. All payments for
     charges shall be made in U.S. Dollars. Monthly Charges shall be invoiced to
     Customer in advance at the beginning of the month. Any additional charges,
     including, but not limited to, any early cancellation charges, accrued
     interest, late fees and any usage-based charges, including, but not limited
     to, charges for network access to the Internet, may be invoiced in arrears.
     In all cases, payments for Services are due within thirty (30) days of the
     invoice date. Amounts that are not paid in full within thirty (30) days of
     the invoice date will be subject to interest charges of the lesser of one
     and one-half percent (1.5%) per month or the highest amount permitted by
     law, which interest shall accrue daily. If Customer does not give WorldCom
     written notice of a dispute with respect to WorldCom charges or taxes
     within six (6) months of the date of an invoice, such invoice shall be
     deemed to correct and binding on Customer. In the event Customer fails to
     pay an invoice within 30 days of invoice date, WorldCom may issue a notice
     of default, and may discontinue the Services and/or terminate this
     Agreement in the event Customer has not fully paid all invoices within
     seven (7) days of the default notice. Customer agrees to pay WorldCom its
     reasonable expenses, including attorney and collection agency fees,
     incurred in enforcing its rights under this Agreement. In the event of
     early cancellation of this Agreement or a Service Order prior to the
     expiration of the Initial Term, Customer will be required to pay 100% of
     the Monthly Charges for each month remaining in the applicable Initial
     Term.
3.2  TAXES. Customer shall be liable for, pay and, to the extent applicable,
     reimburse WorldCom for all local, state, federal and foreign taxes or
     similar assessments or charges (including any interest and penalties
     imposed thereon), arising out of this Agreement or the sale or use of the
     Services hereunder but excluding taxes based on the net income or gross
     receipts of WorldCom. WorldCom will have the right, at any time during any
     term of this Agreement, to pass through and invoice to Customer any new or
     increased fees, assessments, taxes or other charges imposed on, or required
     to be collected by, WorldCom or its subcontractors or agents by any
     governmental agency or its designee. In addition, Customer will pay and be
     solely responsible for all taxes, fees and charges levied directly upon it.
     If Customer provides WorldCom with a duly authorized exemption certificate,
     WorldCom will exempt Customer in accordance with the law, effective on the
     date WorldCom receives the exemption certificate.
3.3  CREDIT APPROVAL. Acceptance of this Agreement or a Service Order is subject
     to Customer meeting WorldCom's standard credit requirements, which may be
     based on commercially available credit reviews (to which Customer hereby
     consents). If WorldCom has reasonable grounds for financial insecurity
     based on Customer's payment history and/or financial solvency or if
     Customer orders additional Services which increase Customer's Monthly
     Recurring Charges by thirty percent (30%), WorldCom may perform an
     additional credit check pursuant to WorldCom's standard credit approval
     procedures. If Customer no longer satisfies WorldCom's standard credit
     requirements, WorldCom may request, and Customer will furnish within ten
     (10) days of such request, adequate assurance of payment or a bond or other
     form of security deposit to assure payment. Interest will be paid on all
     Customer deposits.
                                                                CONTRACT: 361332

4.   USE OF SERVICES.
4.1. WorldCom exercises no control over, and accepts no responsibility for, the
     content of the information passing through WorldCom's host computers,
     network hubs and points of presence (the "WorldCom Network"). All use of
     the WorldCom Network and the Services must comply with the then-current
     version of the WorldCom Acceptable Use Policy ("Policy") which is made a
     part of this Agreement and is available at the following URL:
     www.worldcom.com/terms. WorldCom reserves the right to amend the Policy
     from time to time, effective upon posting of the revised Policy at the URL
     or other notice to Customer. WorldCom reserves the right to suspend the
     Services or terminate this Agreement effective upon notice for a violation
     of the Policy. At WorldCom's request, Customer agrees to indemnify and hold
     harmless WorldCom from any losses, damages, costs or expenses resulting
     from any third party claim or allegation ("Claim") arising out of or
     relating to use of the Space or Services, including any Claim which, if
     true, would constitute a violation of the Policy.
4.2  WorldCom will contact Customer to schedule an installation planning call.
     During that installation planning call, WorldCom and Customer will schedule
     a mutually agreeable installation date, which will be no later than 60 days
     after the date this Agreement is signed or an accepted Service Order was
     submitted (each an "Effective Date"). WorldCom reserves the right to cancel
     this Agreement or the applicable Service Order if Customer is not using the
     Services within 60 days of the applicable Effective Date.
4.3  Customer warrants that any domain name registered or administered on its
     behalf will not violate the trademark or other intellectual property rights
     of any third party and that Customer will comply with the rules and
     procedures of the applicable domain name registries, registrars, or other
     authorities. Customer irrevocably waives any claims against WorldCom that
     may arise in connection with the registration or administration of domain
     name(s). Any Internet Protocol numbers ("IP Numbers") assigned to Customer
     by WorldCom in connection with the Services shall be used only in
     connection with the Services. In the event Customer discontinues use of the
     Services for any reason, or this Agreement expires or is terminated for any
     reason, Customer's right to use the IP Numbers shall terminate.

5.   TERM AND TERMINATION. The term of this Agreement shall commence on the date
     this Agreement is signed by Customer and will terminate on the termination
     or expiration of the last Initial Term under any Service Order. The initial
     term of a Service Order shall be for the period set forth on the Service
     Order ("Initial Term") and shall commence on the Service Activation Date.
     Upon expiration of an Initial Term, the Service Order shall automatically
     renew on a month-to-month basis. Either party may terminate a Service Order
     and/or this Agreement for Cause. Cause shall mean a breach by the other
     party of any material provision of this Agreement, provided that written
     notice of the breach has been given to the breaching party, and the breach
     has not been cured within thirty (30) days after delivery of such notice.
     Notwithstanding the generality of the foregoing, when the breach giving
     rise to Cause only adversely affects a portion of the Services or a Service
     Order, the party seeking to terminate for Cause shall only be entitled to
     terminate those adversely affected Services or the Service Order and not
     this Agreement. In addition, WorldCom shall have the right to terminate
     this Agreement immediately, in the event that Customer ceases to do
     business in the normal course, becomes or is declared insolvent or
     bankrupt, is the subject of any proceeding relating to liquidation or
     insolvency which is not dismissed within ninety (90) days or makes an
     assignment for the benefit of its creditors.

6.   PERMISSIBLE USE OF SPACE.
6.1  Customer may use the Space only for the purposes of installing,
     maintaining, and operating the Equipment. Access to the Facility is
     restricted to Customer's employees and agents. Customer will furnish to
     WorldCom, and keep current, a written list identifying a maximum of five
     individuals authorized to obtain entry to the Facility and access the
     Space. Customer agrees that no individual it authorizes to enter the
     Facility will have been convicted of a felony. Customer assumes
     responsibility for all acts or omissions of the individuals included on
     this list or authorized by Customer to enter the Facility, and agrees to
     indemnify and hold WorldCom harmless from any Claim arising from the acts
     or omissions of these individuals. Customer's employees and agents will
     comply with all applicable laws and ordinances; with the standards and
     practices of the telecommunications industry; and with all WorldCom or
     Facility security procedures, Facility rules, requirements, and safety
     practices. WorldCom may revoke the entry privileges of any person who fails
     to comply with this Agreement, who is disorderly, or who WorldCom
     reasonably suspects will violate this Agreement.
6.2  WorldCom and its designees may observe the work activities of Customer's
     employees and agents in the Facility and may inspect at any time the
     Equipment brought into the Space. Customer's employees and agents shall not
     use any products, tools, materials, or methods that, in WorldCom's
     reasonable judgment, might harm, endanger, or interfere with the Services,
     the Facility, or the personnel or property of WorldCom, its vendors or its
     other customers. WorldCom reserves the right to take any reasonable action
     to prevent such potential harm.
6.3  WorldCom will perform certain services which support the overall operation
     of the Facility (e.g., janitorial services, environmental systems,
     maintenance) at no additional charge to Customer. Customer shall be
     required to maintain the Space in an orderly manner and shall be
     responsible for the prompt removal from the facility of all trash, packing
     material, cartons, etc. that Customer's employees or agents brought to or
     had delivered to the Facility.
6.4  Customer may not make available space within the Space to any third party.
     If Customer makes space available to a third party, Customer shall be in
     breach of this Agreement and WorldCom may pursue any legal or equitable
     remedy, including but not limited to the immediate termination of this
     Agreement.
6.5  Upon termination of this Agreement, Customer is responsible for arranging
     prompt removal of its Equipment from the Facility at Customer's sole risk
     and expense.

7.   CONDUCT IN FACILITY.
7.1  Customer will maintain and operate the Equipment in a safe manner, and keep
     the Space and any portion of the Facility it accesses in good order and
     condition. No employees or agents of Customer will harm or allow any
     attempt to breach the security of the Facility, the Services, or any third
     party system or network at the Facility or accessed by means of the
     Services.
7.2  Customer agrees to use the common areas of the Facility for the purposes
     for which they are intended and abide by any rules governing such common
     areas. Such rules include, but are not limited to, a prohibition against
     smoking in the Facility.
7.3  Customer's employees and agents are prohibited from bringing any of the
     following materials into the Facility: wet cell batteries, explosives,
     flammable liquids or gases, alcohol, controlled substances, weapons,
     cameras, tape recorders, and similar equipment and materials.
7.4  Customer agrees not to alter, tamper with, adjust, or repair any equipment
     or property not belonging to Customer, and agrees not to erect signs or
     devices on the exterior of the storage cabinet or to make any construction
     changes or material alterations to the Space or the interior or external
     portions of the Facility.

8.   EQUIPMENT DEPLOYMENT.
8.1  All Equipment must fit within the Space unless agreed to by WorldCom in an
     addendum to this Agreement. Unless additional power is purchased under a
     particular Service Order, Customer agrees that power consumption will not
     exceed 30 amps 110 VAC per storage cabinet and that all Equipment is UL
     approved. Cabling used by Customer must meet national electrical and fire
     standards and any specifications provided by WorldCom. Customer will be
     allowed to remove from the Facility only that Equipment in which it can
     evidence it has sufficient ownership or possessory interest.
8.2  WorldCom reserves the right to relocate Equipment within the Facility or to
     move Equipment to another facility with at least 45 days' written notice.
     Equipment moved or relocated at WorldCom's initiative will be at WorldCom's

                                                                CONTRACT: 361332
                                 November 9, 2001 Rev. Anil Midha/Scott Thornton
<PAGE>
     expense. Every commercially reasonable effort will be made to minimize
     downtime and service interruption if Equipment is moved or relocated. If
     Customer objects to the location of the new Facility, Customer may
     terminate this Agreement without penalty within sixty days of receiving
     notice of the new Facility's location.
8.3  Customer agrees to immediately remove or render noninfringing, at
     Customer's expense, any Equipment alleged to infringe any patent,
     trademark, copyright, or other intellectual property right.
8.4  If WorldCom negligently or willfully damages any Equipment, WorldCom will
     repair or replace the damaged item or, at WorldCom's option, will reimburse
     Customer for the reasonable cost of repair or replacement.

9.   INDEMNITY. Customer agrees to indemnify WorldCom against actions by any
     person claiming an ownership or possessory interest, lien, trust, pledge,
     or security interest in any Equipment, including without limitation any
     attempt by such third party to take possession of the Equipment. In
     addition, Customer shall indemnify WorldCom against actions by any third
     party based on an alleged violation of the DMCA.

10.  INSURANCE.
10.1 Customer agrees to maintain, at Customer's expense, during the entire time
     this Agreement is in effect: (a) Commercial General Liability Insurance in
     an amount not less than Two Million dollars ($2,000,000) per occurrence for
     bodily injury, personal injury and property damage; (b) Employer's
     Liability Insurance in an amount not less than One Million dollars
     ($1,000,000) per occurrence; (c) Workers' Compensation Insurance in an
     amount not less than that prescribed by statutory limits; (d) Commercial
     Automobile Liability Insurance applicable to bodily injury and property
     damage, covering owned, non-owned, leased and hired vehicles, in an amount
     not less than $1,000,000 per accident; and (e) Umbrella or Excess Liability
     Insurance with a combined single limit of no less than $1,000,000 to apply
     over Commercial General Liability, Employee's Liability, and Automobile
     Liability Insurance.
10.2 Prior to taking occupancy of the Space, Customer shall furnish WorldCom
     with certificates of insurance which evidence the minimum levels of
     insurance set forth herein and which name WorldCom as an additional
     insured. The Commercial General liability insurance shall contain the
     "Amendment of the Pollution Exclusion" endorsement for damage caused by
     heat, smoke or fumes from a hostile fire. In the event the Facility's
     landlord, pursuant to a lease relevant to a particular Space, requires
     additional insurance, Customer hereby agrees to comply with the landlord's
     requirements under the lease, as the lease may be modified from time to
     time.
10.3 None of WorldCom, WorldCom's subsidiaries, parent companies, or affiliates
     shall insure or be responsible for any loss or damage to property of any
     kind owned or leased by Customer or by its employees and agents other than
     losses or damages resulting from negligence or willful acts of such
     parties. Any insurance policy covering the Equipment against loss or
     physical damage shall provide that underwriters have given their permission
     to waive their rights of subrogation against WorldCom, WorldCom
     subsidiaries, affiliates, the Facility landlord, and their respective
     directors, officers and employees.
10.4 Customer will insure or self-insure against claims involving Customer's
     employees and agents. Customer agrees to release and indemnify WorldCom
     against claims by any of Customer's employees and agents arising from
     dismissal, suspension, or termination of work, or from denial of entry to
     the Facility; and claims by any person arising from Customer's nonpayment
     for the Space or the Services.

11.  SERVICE LEVEL AGREEMENT. The Service Level Agreement ("SLA") for this
     service, which is made a part of this Agreement, is set forth at the
     following URL: www.worldcom.com/terms and applies only to Customers
     agreeing to a Term Commitment of at least one year. WorldCom reserves the
     right to amend the SLA from time to time effective upon posting of the
     revised SLA to the URL or other notice to Customer; provided, that in the
     event of any amendment resulting in a material reduction of the SLA's
     service levels or credits, Customer may terminate this Agreement without
     penalty by providing WorldCom written notice of termination during the 30
     days following notice of such amendment. The SLA sets forth Customer's sole
     and exclusive remedies for any claim relating to this service or the
     WorldCom Network, including any failure to meet any guarantee set forth in
     the SLA. WorldCom's records and data shall be the basis for all SLA
     calculations and determinations. Notwithstanding anything to the contrary,
     the maximum amount of credit in any calendar month under the SLA shall not
     exceed the Monthly Charge and/or Initial Fee which, absent the credit,
     would have been charged for WorldCom service that month.

12.  LIMITATION OF DAMAGES. EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES,
     IN NO EVENT SHALL EITHER PARTY OR ANY OF WORLDCOM'S SUPPLIERS OR LICENSORS
     BE LIABLE FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, PUNITIVE, OR INCIDENTAL
     DAMAGES OF ANY KIND (INCLUDING BUT NOT LIMITED TO LOSS OF USE, INTERRUPTION
     OF BUSINESS, LOST PROFITS, LOST REVENUE, OR LOST DATA), NOR SHALL
     WORLDCOM'S SUPPLIERS OR LICENSORS BE LIABLE FOR DIRECT DAMAGES TO THE
     EXTENT PERMITTED BY APPLICABLE LAW. In no event shall WorldCom's aggregate
     liability IN CONNECTION WITH this Agreement for all claims (whether in
     contract, tort (INCLUDING NEGLIGENCE), statute, or otherwise) exceed the
     lesser of US$100,000 or the amounts paid to WorldCom FOR THE SERVICES
     GIVING RISE TO A CLAIM in the twelve months PRECEDING THE DATE OF SUCH
     CLAIM. Customer agrees and acknowledges that it is in a better position to
     foresee and evaluate any potential damage or loss it may suffer in
     connection with the Services and that the fees payable under this Agreement
     have been calculated on the basis that WorldCom shall exclude liability as
     set out in this Section.

13.  NO WARRANTY. WORLDCOM PROVIDES THE SPACE AND THE SERVICES AS IS. EXCEPT AS
     EXPRESSLY SET FORTH IN SECTION 11 ABOVE, IN CONNECTION WITH THE SERVICES,
     WORLDCOM (A) MAKES NO WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED
     FOR THE SERVICES IT IS PROVIDING, AND (B) DISCLAIMS ANY WARRANTY OF TITLE,
     MERCHANTABILITY, NONINFRINGEMENT AND FITNESS FOR A PARTICULAR PURPOSE AND
     WARRANTIES ARISING FROM A COURSE OF DEALING, USAGE, OR TRADE PRACTICE
     WorldCom specifically denies any responsibility for the accuracy or quality
     of information obtained through the Services. Use of any information
     obtained via the Services is at Customer's own risk.

14.  NO ESTATE OR PROPERTY INTEREST. Customer acknowledges that it has been
     granted only a license to occupy the designated portions of the Facility
     and that it has not been granted any real property interests in the Space
     or the Facility. Payments by Customer under this Agreement do not create or
     vest in Customer (or in any other person) any leasehold estate, easement,
     ownership interest, or other property right or interest of any nature in
     any part of the Facility. The parties intend that Equipment, whether or not
     physically affixed to the Facility, shall not be construed to be fixtures.
     Customer (or the lessor of the Equipment, if applicable) will report the
     Equipment as its personal property wherever required by applicable laws,
     and will pay all taxes levied upon such Equipment.

15.  FORCE MAJEURE. WorldCom shall not be deemed to be in default of any
     provision of this Agreement or be liable for any delay or failure in
     performance due to Force Majeure, which shall include without limitation
     acts of God, earthquake, weather conditions, labor disputes, changes in
     law, regulation or government policy, riots, war, fire, epidemics, acts or
     omissions of vendors or suppliers, equipment failures, transportation
     difficulties, malicious or criminal acts of third parties, or other
     occurrences which are beyond WorldCom's reasonable control.

16.  DAMAGE TO THE SPACE.
16.1 If the Space is damaged due to a Force Majeure event, WorldCom shall give
     prompt notice to Customer of such damage, and may temporarily relocate
     Equipment to new Space or a new Facility, if practicable. If the Facility's
     landlord or WorldCom exercises an option to terminate a particular lease
     due to damage or destruction of the Space, or if WorldCom decides not to
     rebuild the Space, this Agreement shall terminate as of the date of the
     damage. Monthly Fees for Space and Services shall proportionately abate for
     the period from the date of such damage.

                                                                CONTRACT: 361332
