or condition its consent. An equitable adjustment shall be made if such change

performed under this Agreement. Such cost adjustment shall be made on the basis
of the actual cost of the Work, unless otherwise agreed in writing. No course of
dealing or failure of either Party to strictly enforce any term, right or
condition of this Agreement shall be construed as a general waiver or

or obligations under this Agreement, except with the prior written consent of
the other Party, which consent will not be unreasonably withheld; provided,
however, that CINGULAR will have the right to assign this Agreement to any

or (iv) the assignment denies, alters or attempts to alter any of the
non-assigning Party's rights hereunder.

3.4 CANCELLATION AND TERMINATION

a.   Cancellation:

     1.   If either Party fails to cure a material default under this Agreement
          or applicable Order within *** after written notice, then, in addition
          to all other rights and remedies, the Party not in default may cancel
          this Agreement and/or the Order under which the default occurred.
          Notwithstanding the foregoing, if the material default is a breach of
          the Compliance with Laws Section of this Agreement, the Party not in
          default may, upon providing written notice, cancel the Agreement ***.
          Additional provisions for Cancellation of Orders hereunder are set
          forth in this Agreement.

     2.   If Supplier is the Party in default, CINGULAR may Cancel any Orders
          which may be affected by Supplier's default without any financial
          obligation or Liability on the part of CINGULAR whatsoever, except to
          pay for the value of any Material and/or Services retained by
          CINGULAR.

b.   Termination:

     CINGULAR may Terminate this Agreement or any Order, in whole or in part, at
     any time, upon written notice to Supplier. In such event, or if Supplier
     Cancels this Agreement or any Order as a result of CINGULAR's failure to
     cure a material default, CINGULAR shall pay Supplier its actual and direct
     costs incurred to provide the Material and Services ordered by CINGULAR,
     but no more than a percentage of the Services performed or Material
     Delivered, less reimbursements. If requested, Supplier agrees to
     substantiate such costs with proof satisfactory to CINGULAR. In no event
     shall CINGULAR's Liability exceed the price of any Material or Services
     ordered hereunder. After the receipt of CINGULAR's payment for any
     Services, Supplier shall deliver the physical embodiments, if any, of such
     Services. The foregoing statement of CINGULAR's Liability states the entire
     Liability of CINGULAR and Supplier's sole remedy for CINGULAR's Termination
     for convenience, or Supplier's Cancellation for material default.

c.   Partial Cancellation and Termination:

     Where a provision of this Agreement or the applicable Laws permit CINGULAR
     to Terminate or Cancel an Order, such Termination or Cancellation may, at
     CINGULAR's option, be either complete or partial. In the case of a partial
     Termination or Cancellation, CINGULAR may, at its option, Accept a portion
     of the Material or Services covered by an Order and pay Supplier for such
     Material or Services at the unit prices set forth in such Order. The right
     to cancel an Order shall also include the right to cancel any other related
     Order.

3.5 COMPLIANCE WITH LAWS

Supplier shall comply with all applicable federal, state, county, and local
rules, including, without limitation, all statutes, laws, ordinances,
regulations and codes ("Laws"). Supplier's obligation to comply with all Laws
includes the procurement of permits, certificates, approvals, inspections and
licenses, when needed, in the performance of this Agreement. Supplier further
agrees to comply with all applicable Executive and Federal regulations as set
forth in "Executive Orders and Federal Regulations," a copy of which is attached
as Appendix 3.5 and by this reference made a part of this Agreement. Supplier
shall defend, indemnify and hold CINGULAR harmless from and against any
Liability that may be sustained by reason of Supplier's failure to comply with
this Section.

3.6 CONFLICT OF INTEREST

Supplier represents and warrants that no officer, director, employee, or agent
of CINGULAR has been or will be employed, retained or paid a fee, or otherwise
has received or will receive any personal compensation or consideration, by or
from Supplier or any of Supplier's officers, directors, employees or agents in
connection with the obtaining, arranging or negotiation of this Agreement or
other documents entered into or executed in connection with this Agreement.

3.7 CONSTRUCTION AND INTERPRETATION

a.   The language of this Agreement shall in all cases be construed simply, as a
     whole and in accordance with its fair meaning and not strictly for or
     against any Party. The Parties agree that this Agreement has been prepared
     jointly and has been the subject of arm's length and careful negotiation.
     Each Party has been given the opportunity to independently review this
     Agreement with legal counsel and other consultants, and each Party has the
     requisite experience and sophistication to understand, interpret and agree
     to the particular language of the provisions. Accordingly, in the event of
     an ambiguity in or dispute regarding the interpretation of this Agreement,
     the drafting of the language of this Agreement shall not be attributed to
     either Party.

b.   Article, section and paragraph headings contained in this Agreement are for
     reference purposes only and shall not affect the meaning or interpretation
     of this Agreement. The use of the word "include" shall mean "includes, but
     is not limited to." The singular use of words shall include the plural and
     vice versa. Except as otherwise specified, Supplier's price for Material
     and Services includes the price for all related Material or Services
     necessary for CINGULAR to use the Material and/or Services for its intended
     purpose, as well as all other Supplier obligations under this Agreement.
     All obligations and rights of the Parties are subject to modification as
     the parties may specifically provide in an Order. "Services" and "Software"
     shall be treated as "goods" for purposes of applying the provisions of the
     Uniform Commercial Code ("UCC"). If there is an inconsistency or conflict
     between the terms in this Agreement and in an Order, the terms in the Order
     shall take precedence.

3.8 CUMULATIVE REMEDIES

Except as specifically identified as a Party's sole remedy, any rights of
Cancellation, Termination, Liquidated Damages or other remedies prescribed in
this Agreement, are cumulative and are not exclusive of any other remedies to
which the injured Party may be entitled. Neither Party shall retain the benefit
of inconsistent remedies.

3.9 DELIVERY, PERFORMANCE AND ACCEPTANCE

Services performed by Supplier shall be deemed to be accepted by CINGULAR when
Services are performed to CINGULAR's satisfaction. Payments, including progress
payments, if any, shall not be construed as Acceptance of Services performed up
to the time of such payments. CINGULAR shall notify Supplier of any Services
considered to be unsatisfactory. Supplier shall, at no charge to CINGULAR, take
prompt action to correct such unsatisfactory Services. If such unsatisfactory
Services have not been corrected within a reasonable time (not to exceed ***
from date of notification), CINGULAR may, in addition to all other rights and
remedies provided by law or this Agreement, Cancel this Agreement and/or any
affected Order.

     matter contained herein. This Agreement supercedes all prior oral and
     written communications, agreements and understandings of the Parties, if
     any, with respect hereto. Acceptance of Material or Services, payment or
     any inaction by CINGULAR, shall not constitute CINGULAR's consent to or
     Acceptance of any additional or different terms from those stated in this
     Agreement, except for terms in an Order inserted by CINGULAR and signed by
     both Parties. Estimates furnished by CINGULAR are for planning purposes
     only and shall not constitute commitments. Supplier covenants never to
     contend otherwise.

b.   No oral promises or statement have induced either Party to enter into this
     Agreement, and the Parties agree that the Agreement's express language may
     only be modified or amended through a subsequent written document signed by
     the Parties.

3.11 FORCE MAJEURE

a.   Neither Party shall be deemed in default of this Agreement or any Order to
     the extent that any delay or failure in the performance of its obligations
     results from any cause beyond its reasonable control and without its fault
     or negligence, such as acts of God, acts of civil or military authority,
     embargoes, epidemics, war, riots, insurrections, fires, explosions,
     earthquakes, floods or strikes ("Force Majeure").

b.   If any Force Majeure condition affects Supplier's ability to perform,
     Supplier shall give immediate notice to CINGULAR, and CINGULAR may elect to
     either: (i) Terminate the affected Order(s) or any part thereof, (ii)
     suspend the affected Order(s) or any part thereof for the duration of the
     Force Majeure condition, with the option to obtain Material and Services to
     be furnished under such Order(s) elsewhere, and deduct from any commitment
     under such Order(s), the quantity of the Material and Services obtained
     elsewhere or for which commitments have been made elsewhere, or (iii)
     resume performance under such Order(s) once the Force Majeure condition
     ceases, with an option in CINGULAR to extend any affected Delivery Date for
     the length of time that the Force Majeure condition existed. Unless
     CINGULAR gives written notice within thirty (30) days after being notified
     of the Force Majeure condition, option (ii) shall be deemed selected.

3.12 GOVERNING LAW

This Agreement and performance hereunder shall be governed by the Laws of the
State of Georgia, exclusive of its choice of law provisions.

3.13 INDEMNITY

TO THE FULLEST EXTENT PERMITTED BY LAW, SUPPLIER SHALL DEFEND, INDEMNIFY AND
HOLD HARMLESS CINGULAR AND ITS AFFILIATES (INCLUDING THEIR EMPLOYEES, OFFICERS,
DIRECTORS, AGENTS AND CONTRACTORS) AGAINST ANY LIABILITY ARISING FROM OR
INCIDENTAL TO SUPPLIER'S OBLIGATIONS UNDER THIS AGREEMENT OR THE MATERIAL OR
SERVICES PROVIDED BY SUPPLIER, INCLUDING (i) INJURIES TO PERSONS, INCLUDING
DEATH OR DISEASE, (ii) DAMAGES TO PROPERTY, INCLUDING THEFT, (iii) SUPPLIER'S
FAILURE TO COMPLY WITH ALL LAWS, AND (iv) LIENS ON CINGULAR'S PROPERTY.

b.   IT IS THE INTENT OF THE PARTIES THAT THIS INDEMNITY APPLY REGARDLESS OF
     WHETHER OR NOT SUCH LIABILITY WAS CAUSED IN PART BY CINGULAR'S OWN
     NEGLIGENCE OR THAT OF THE OTHER PARTIES INDEMNIFIED UNDER THIS SECTION,
     EXCLUDING ONLY ANY LIABILITY ARISING FROM THE SOLE NEGLIGENCE OF CINGULAR.
     THIS INDEMNITY SHALL SURVIVE THE DELIVERY, INSPECTION AND ACCEPTANCE OF THE
     MATERIAL OR SERVICES AND THE CANCELLATION, TERMINATION OR EXPIRATION OF
     THIS AGREEMENT.

                                                       Agreement Number SG021306

CINGULAR shall notify Supplier within a reasonable period of time of any written
claim, demand, notice or legal proceedings ("Claim") for which Supplier may be
responsible under this indemnity obligation. A delay in notice shall not relieve
Supplier of its indemnity obligation, except to the extent Supplier can show it
was prejudiced by the delay.

c.   Supplier shall assume, at its expense, the sole defense of the Claim
     through counsel selected by Supplier and shall keep CINGULAR fully informed
     as to the progress of such defense. Upon reasonable request of Supplier and
     at Supplier's expense, CINGULAR shall cooperate with Supplier in the
     defense of the Claim. At its option and expense, CINGULAR may retain or use
     separate counsel to represent it, including in-house counsel. Supplier
     shall maintain control of the defense, except that if the settlement of a
     Claim would adversely affect CINGULAR, Supplier may settle the Claim as to
     CINGULAR only with its consent, which consent shall not be withheld or
     delayed unreasonably. Supplier shall pay the full amount of any judgment,
     award or settlement with respect to the Claim and all other expenses
     related to the resolution of the Claim, including costs, interest and
     reasonable attorneys' fees. If CINGULAR is required to take any action to
     enforce its indemnity rights under this Agreement, or to assume the defense

communications networks, computer systems/applications/software, network
elements and their support systems, and the information stored, transmitted, or
processed using these resources ("Information Resources.") "Contractor" means a
person or business entity with a written agreement ("Agreement") to perform
services for Cingular. "User" means any individual performing services under the
Agreement, whether as an employee, approved subcontractor, or agent of
Contractor. "Cingular Sponsor" means the Cingular management employee
responsible for the oversight of the services provided by Contractor.

These Requirements apply to Contractors and Users performing services on
Cingular premises or remotely accessing Cingular infrastructure, systems or
applications using Cingular-provisioned client-VPN and to those providing
services to Cingular that are hosted external to Cingular premises.

A. COMPLIANCE WITH LAW AND GENERAL POLICY. Contractors must comply with the
"CINGULAR CORPORATE INFORMATION SECURITY POLICY" as set forth on Exhibit 1.
Contractors must protect Cingular Information Resources and Cingular proprietary
or confidential data or information in accordance with the terms and conditions
of the Agreement (including any separate confidentiality agreements), and must
comply with all applicable international, federal, state, and local laws and
regulations related to use of Information Resources and protection of Cingular's
data or information. Contractor is responsible for ensuring that all Users it
employs or contracts with comply with these Requirements. Additionally,
regarding its Users, Contractor shall:

1.   Ensure that all Users are covered by a legally binding obligation that
     protects Cingular's proprietary and confidential information and are
     briefed on these Requirements.

2.   Perform a criminal background check on each User prior to allowing the User
     to access an Information Resource, and not allow such access if the User
     has been convicted of or is currently awaiting trial for a felony offense
     or a misdemeanor related to computer security, theft, fraud or violence.

          economically disadvantaged individuals and small business concerns
          owned and controlled by women shall have the maximum practicable

          policy of the United States that its prime SUPPLIERs establish

          concerns owned and controlled by socially and economically
          disadvantaged individuals and small business concerns owned and
          controlled by women.

          performance. The SUPPLIER further agrees to cooperate in any studies
          or surveys as may be conducted by the United States Small Business

          more socially and economically disadvantaged individuals; or, in the

          disadvantaged Indian tribe or Native Hawaiian Organization, and which

          Americans, Hispanic Americans, Native Americans, Asian-Pacific
          Americans, Subcontinent Asian Americans, and other minorities, or any
          other individual found to be disadvantaged by the Administration
          pursuant to section 8(a) of the Small business Act. The SUPPLIER shall
          presume that socially and economically disadvantaged entities also
          include Indian Tribes and Native Hawaiian Organizations.

     (D)  The term "small business concern owned and controlled by women" shall
          mean a small business concern (i) which is at least 51 percent owned
          by one or more women, or, in the case of any publicly owned business,

          women, and (ii) whose management and daily business operations are
          controlled by one or more women; and

          their sub-SUPPLIERs regarding their status as a small business
          concern, a small business concern owned and controlled by socially and
          economically disadvantage individuals or a small business concern
          owned and controlled by women.

     The objectives for the Order Management Center ("OMC") are to establish and
     manage scalable, reliable and flexible center operations. The OMC will
     focus on meeting service level agreements ("SLAs") for sales transaction
     processing, inbound call handling and customer contacts for Cingular
     Online. STI is required to closely adhere to all of Cingular's business
     processes and security standards in performing its OMC Services to ensure a
     seamless Cingular branded customer experience. The OMC will support
     business from Cingular Online consumer and business customers.

     3.1 TRANSACTION PROCESSING

     The primary source of transaction volumes will be generated from Cingular
     front -end clients (e.g., Premiere and Overdrive). The goal of the OMC is
     to consistently deliver against the SLA commitments. The OMC operating
     hours will be flexible to support the overall Cingular Online objectives.
     The OMC will operate seven days a week and will support the hours of
     operation required by Cingular Online including 7x24 OMC support.

     3.2 ORDER VOLUME SCOPE

     Order volume commitments will be adjusted ***. A *** forecast will be
     provided to STI by Cingular on the ***. The forecast will provide STI with

     handling order volume and user load. The *** will contain a full compliment
     of network infrastructure including firewalls, load balancers and
     high-speed switches to ensure all network connectivity is equivalent to
     production as well.

     A *** will be implemented to ensure that a full copy of the production
     database is maintained in the *** at all times. In the event of a total
     service disruption in the *** facility, the *** will be reconfigured to
     access the production database and provide the production instance of the
     Cingular Online ASP system.

     6.2 DR SERVICE LEVELS

     The following service levels are associated with the DR solution:

          -    Service restoration time: ***

          -    System performance level: equal to production in terms of user
               and order volume

          -    System SLA's: same as for production (Addendum B). System will
               conform to the requirements of Section 5.0 of this document

     NOTE: This solution will rely on the implementation of a dedicated, private
     circuit (e.g. friends net connection) between STI's Bridgewater, NJ office
     and Cingular's Bothell, WA facility.

          -    DR test will be performed *** times *** at a mutually agreed to
               time by both parties.

7.0 CINGULAR TERMINATION FOR CONVENIENCE AND BUY-OUT PROVISION

     In the event Cingular desires to terminate the SOW prior to the end of its
     term, Cingular may exercise its right for Termination for Convenience as
     described in Section 7.1. In addition, STI may provide transition services
     subject to a mutually agreeable SOW that may include the following terms:

          1.   Specific key milestones and dates in which Cingular can exercise
               the right to migrate all or part of the ActivationNow(R) Platform
               and the OMC Services to a Cingular location.

          2.   Identification of the work effort needed and the related costs to
               establish a mutually acceptable SOW to help transition the
               production environment to Cingular.

     7.1 CINGULAR TERMINATION FOR CONVIENENCE

          1.   If Cingular or STI terminates for convenience with less than ***
               notice, Cingular or Synchronoss (whichever party terminates) will
               pay the other a termination fee equal to ***% of the previous ***
               average manual and automated order processing and inbound call
               transaction processing cost x *** (the "Termination Fee").

          2.   In the case of a termination by Cingular, Cingular will not be
               required to pay the Termination Fee if it provides STI with at
               least *** notice of such termination and the traffic during the
               ramp down period is equal to or more than ***% of the previous
               *** average manual and automated order processing and inbound
               call transaction processing volume x ***.

     7.2 DEDICATED INFRASTRUCTURE BUYOUT

          1.   Upon any termination of the PSA or this SOW prior to expiration
               of the Initial Term, Cingular may, at its discretion, pay the
               applicable Buyout Fee set forth in Table 2 below in exchange for
               ownership of the Dedicated Infrastructure (if Cingular elects not
               to pay the Buyout Fee, then STI shall retain ownership of the
               Dedicated Infrastructure). At the end of the *** of the Term of
               the Agreement, ownership of the Dedicated Infrastructure will
               automatically vest in Cingular without further action.

1.0  TRANSACTION PRICING SCHEDULE

     This section of the SOW provides the transaction and service fees
     associated with the Agreement. The service fees in this SOW go into effect
     on the Effective Date of the Agreement. Modifications to any of the prices
     herein need to be in writing, and mutually agreed upon by both parties.

     1.1  PLATFORM SERVICE FEE

     Table 1 represents the API "click stream" transaction fee for the Order
     Gateway, Order Manager and Reporting Platform. The gateway fee is applied
     to every transaction received by the Order Gateway.

                      T3     *** Average Transactions (Calculated ***)             $***
</TABLE>

* T = Transaction Service Fee

1.   The Transaction Service Fee assumes transactions may contain a maximum of
     five lines of service per transaction. Exceptions include e.g., bulk orders
     may require a special handling/transaction processing charge.

2.   The Transaction Price applies to all transactions in that tier. For
     example, if the Order Gateway receives *** transactions per ***, the
     Transaction Price for transactions *** will be at Tier 2 pricing for each
     order received.

     Cingular shall guarantee *** transactions per ***. In the event that the
     transaction volume in a *** is less than *** transactions, Cingular shall
     pay Tier 1 pricing for each transaction under the guaranteed *** minimum of
     *** transactions.

3.   For example, *** commitment = *** transactions. The actual received = ***
     for a total shortfall of *** transactions for the ***. Cingular would pay a
     total of $*** for the *** shortfall (*** transactions x tier 1 pricing).
     Notwithstanding anything herein to the contrary, if the initial or final
     period of the term of the Agreement does not span an entire *** , the
     guaranteed minimum shall be a prorated number based on the actual time
     period.

2.0 FORECASTING

     2.1 TRANSACTION FORECAST

     Cingular will provide Synchronoss with a *** forecast on or about *** of
     each ***. The forecast will provide Synchronoss with the automated and
     manual transaction volume requirements for the following *** detailed by
     ***. If the forecast is not received *** after the *** of each ***
     Synchronoss Technologies (STI) will invoke the prior *** forecast.

     In the event the actual transaction volume for a given *** does not achieve
     *** % of the *** forecast or *** % of the *** forecast, whichever is
     greatest then STI will invoice Cingular a minimum *** fee based on *** % of
     the *** or *** % of the *** forecasted transactions.

     2.2 CALL VOLUME FORECAST

     Cingular will provide Synchronoss with the expected call volume
     requirements for the following *** detailed by ***. If the forecast is not
     received *** after the *** of each *** Synchronoss Technologies (STI) will
     invoke the prior *** forecast for inbound calls.

3.0 PRICING ASSUMPTIONS

     1.   STI and Cingular will meet once every *** to review and adjust the
          transaction prices where appropriate.

     2.   Synchronoss and Cingular agree to review and adjust where appropriate
          the B2B IRU manual transaction processing fees *** after partial
          automation is implemented for this transaction. Cingular will
          determine, at its option, when this review will take place. Any
          adjustment to the manual processing fees will be mutually agreed to by
          both parties and the pricing table amended as soon as possible.

     3.   Within *** after signature of the SOW, STI agrees to meet and reassess
          the baseline cost and service levels in this SOW. Any adjustments
          would be mutually agreed to by both parties

     4.   In the event that the time studies reveal a material change in costs,
          greater than *** %, both parties agree to review in detail the core
          reason for the change. In the event that a change is attributed to
          performance, then both parties will mutually agree if a change is
          warranted.

     5.   The service fee in this appendix is for processing a completed or
          cancelled transaction through the Order Gateway and OMC.

     6.   Service levels apply only to transactions that are processed through
          the existing ASP infrastructure. Exception handling, workarounds or
          transactions that do not flow through the Order Gateway and OMC will
          be excluded from the service levels and remedies defined in Addendum
          B.

     7.   STI anticipates processing additional transaction types. These
          transactions could be priced at a different rate. The rate for new
          transactions would be determined by the complexity and processing
          rates associated with the transaction. Transaction prices will be
          determined after a large enough sample size is processed by the OMC
          and will be mutually agreed to in writing by both parties. During this
          period STI will either process these transactions on a exception
          handling basis or would mutually agree on a price until an amendment
          is completed to Addendum A and Addendum B with mutually agreed upon
          pricing and associated SLA and remedies.

     8.   New transactions not identified in Section 3.0 of this SOW would be
          handled through a written change request. New transactions will
          require an initial trial period that will produce a large enough
          sample size to price the transaction. Service levels and remedies will
          not apply during the initial trial period.

     9.   STI anticipates the cancelled rate for manually processed transactions
          not to exceed *** % of total transaction volume. If the cancelled rate
          for manually processed orders exceeds *** % STI will charge Cingular
          the shipped /successful transaction rate.

     10.  Any modifications requested by Cingular that impact the configuration
          or processing methodology by STI may require pricing adjustments.

2.0  ASP PLATFORM SERVICE LEVELS AND REMEDIES

     2.1  STI ORDER GATEWAY AND WORKFLOW MANAGER AVAILABILITY

     SYSTEM AVAILABILITY:

     The Order Gateway and Workflow Manager is available 24 hours a day, 7 days
     per week excluding 1) regularly scheduled downtimes to perform system
     upgrades, application administration, and any other planned events and 2)
     STI written requests to customer for any unscheduled maintenance outage
     periods, if needed.

     ASP PLATFORM SERVICE LEVELS:

     1.   Order Gateway and associated workflow processes - *** % system up time

     2.   Email Service - *** % system up time

     3.   Workflow Manager - *** % system up time

     4.   Housekeeping and other scheduled system processes e.g., Fedx Tracker
          job - *** % system uptime

     5.   Reporting Platform - *** % system up time

     SERVICE LEVEL MEASUREMENT PROCESS:

     1.   Statistics used to determine downtime are collected using a suite of
          network and application monitoring tools as well as data collected by
          the application itself.

     2.   ASP Platform Service level attainment is reviewed on a *** basis. All
          statistics from STI's monitoring suite are reviewed and dowtime
          recorded for that week is summarized for each funtional area of the
          ASP platform (e.g. gateway, email, workflow etc.)

     3.   STI assumes that the *** and *** transaction volume will not exceed
          the forecast by more than *** %. Volume in excess of this amount will
          exempt STI from these SLA and Remedies for the affected period.
          Requirements for special events, e.g. bulk orders will be addressed on
          an individual basis.

     4.   Functional area outages are determined using the guidelines in the
          tables below:
