                                       OF

                                 ROO GROUP, INC.

1.       PURPOSES OF THE PLAN

         The  purposes of the 2004 Stock  Option Plan (the "Plan") of ROO Group,
Inc., a Delaware corporation (the "Company"), are to:

         (a) Encourage selected employees,  directors and consultants to improve
operations and increase profits of the Company;

         (b) Encourage selected  employees,  directors and consultants to accept
or continue  employment or  association  with the Company or its  Affiliates (as
defined hereinafter); and

         (c)  Increase  the  interest  of  selected  employees,   directors  and
consultants  in the Company's  welfare  through  participation  in the growth in
value of the common stock of the Company (the "Shares").

         Options  granted under this Plan  ("Options")  may be "incentive  stock
options"  ("ISOs")  intended to satisfy the  requirements  of Section 422 of the
Internal Revenue Code of 1986, as amended,  and the regulations  thereunder (the
"Code"), or "non-qualified stock options" ("NQSOs").

2.       ELIGIBLE PERSONS

         Every  person who at the date of grant of an Option is an  employee  of
the Company or of any  Affiliate of the Company is eligible to receive  NQSOs or
ISOs under this Plan.  Every person who at the date of grant is a consultant to,
or  non-employee  director  of, the Company or any  Affiliate  of the Company is
eligible to receive NQSOs under this Plan.  The term  "Affiliate" as used in the
Plan means a parent or  subsidiary  corporation  as  defined  in the  applicable
provisions  (currently  Sections 424(e) and (f),  respectively) of the Code. The
term  "employee"  includes  an officer or  director  who is an  employee  of the
Company.  The term  "consultant"  includes  persons  employed  by, or  otherwise
affiliated with, a consultant.

3.       STOCK SUBJECT TO THIS PLAN; MAXIMUM NUMBER OF GRANTS

         Subject  to the  provisions  of  Section  6.1.1 of the Plan,  the total
number of Shares which may be issued under Options granted pursuant to this Plan
shall not exceed Fifty Million  (50,000,000)  Shares.  The Shares covered by the
portion  of any grant  under the Plan which  expires  unexercised  shall  become
available again for grants under the Plan.

4.       ADMINISTRATION

         (a) The Plan shall be  administered by either the Board of Directors of
the  Company  (the  "Board")  or  by a  committee  (the  "Committee")  to  which
administration  of the Plan,  or of part of the Plan,  may be  delegated  by the
Board (in either case, the "Administrator").  The Board shall appoint and remove
members  of such  Committee,  if  any,  in its  discretion  in  accordance  with
applicable  laws.  If  necessary  in order to comply  with Rule 16b-3  under the
Securities  Exchange Act of 1934,  as amended (the  "Exchange  Act") and Section
162(m) of the Code, the Committee shall, in the Board's discretion, be comprised
solely of  "non-employee  directors"  within the  meaning of said Rule 16b-3 and
"outside  directors"  within  the  meaning of  Section  162(m) of the Code.  The
foregoing  notwithstanding,  the  Administrator  may  delegate  nondiscretionary
administrative  duties to such  employees  of the Company as it

<PAGE>

deems proper and the Board, in its absolute discretion, may at any time and from
time to time exercise any and all rights and duties of the  Administrator  under
the Plan.

         (b) Subject to the other  provisions  of this Plan,  the  Administrator
shall have the  authority,  in its  discretion:  (i) to grant  Options;  (ii) to
determine  the fair  market  value of the Shares  subject to  Options;  (iii) to
determine the exercise price of Options  granted;  (iv) to determine the persons
to whom,  and the time or times at  which,  Options  shall be  granted,  and the
number of shares  subject to each Option;  (v) to interpret  this Plan;  (vi) to
prescribe, amend, and rescind rules and regulations relating to this Plan; (vii)
to determine the terms and  provisions of each Option granted (which need not be
identical),  including  but not limited  to, the time or times at which  Options
shall be  exercisable;  (viii)  with the consent of the  optionee,  to modify or
amend any Option;  (ix) to defer (with the consent of the optionee) the exercise
date of any  Option;  (x) to  authorize  any  person to execute on behalf of the
Company any instrument  evidencing the grant of an Option;  and (xi) to make all
other  determinations  deemed necessary or advisable for the  administration  of
this Plan. The Administrator may delegate nondiscretionary administrative duties
to such employees of the Company as it deems proper.

         (c) All questions of interpretation, implementation, and application of
this Plan shall be determined by the Administrator. Such determinations shall be
final and binding on all persons.

5.       GRANTING OF OPTIONS; OPTION AGREEMENT

         (a) No Options shall be granted under this Plan after 10 years from the
date of adoption of this Plan by the Board.

         (b) Each Option shall be evidenced by a written stock option agreement,
in form  satisfactory  to the  Administrator,  executed  by the  Company and the
person to whom such Option is granted.

         (c) The stock option  agreement  shall  specify  whether each Option it
evidences is an NQSO or an ISO.

         (d) Subject to Section  6.3.3 with respect to ISOs,  the  Administrator
may approve the grant of Options  under this Plan to persons who are expected to
become  employees,  directors  or  consultants  of  the  Company,  but  are  not
employees,  directors or  consultants  at the date of approval,  and the date of
approval shall be deemed to be the date of grant unless  otherwise  specified by
the Administrator.

6.       TERMS AND CONDITIONS OF OPTIONS

         Each Option  granted  under this Plan shall be subject to the terms and
conditions  set forth in Section  6.1.  NQSOs shall also be subject to the terms
and conditions set forth in Section 6.2, but not those set forth in Section 6.3.
ISOs shall also be subject to the terms and conditions set forth in Section 6.3,
but not those set forth in Section 6.2.

         6.1 Terms and Conditions to Which All Options Are Subject.  All Options
granted under this Plan shall be subject to the following terms and conditions:

                  6.1.1 Changes in Capital Structure.  Subject to Section 6.1.2,
if the stock of the Company is changed by reason of a stock split, reverse stock
split, stock dividend,  or  recapitalization,  combination or  reclassification,
appropriate  adjustments  shall be made by the Board in (a) the number and class
of shares of stock subject to this Plan and each Option  outstanding  under this
Plan, and (b) the exercise price of each outstanding Option; provided,  however,
that the Company shall not be required to issue fractional shares as a result of
any such  adjustments.  Each such adjustment shall be subject to approval by the
Board in its sole discretion.

                  6.1.2  Corporate  Transactions.  In the event of the  proposed
dissolution or liquidation of the Company,  the Administrator  shall notify each
optionee  at least 30 days  prior to such  proposed  action.  To the  extent not
previously  exercised,  all  Options  will  terminate  immediately  prior to the
consummation of such proposed action;

<PAGE>

provided,  however,  that  the  Administrator,  in  the  exercise  of  its  sole
discretion, may permit exercise of any Options prior to their termination,  even
if such  Options  were not  otherwise  exercisable.  In the event of a merger or
consolidation of the Company with or into another corporation or entity in which
the Company does not survive,  or in the event of a sale of all or substantially
all of the  assets of the  Company  in which  the  shareholders  of the  Company
receive securities of the acquiring entity or an affiliate thereof,  all Options
shall be assumed or  equivalent  options shall be  substituted  by the successor
corporation  (or other  entity)  or a parent  or  subsidiary  of such  successor
corporation (or other entity);  provided,  however,  that if such successor does
not agree to assume the Options or to substitute  equivalent  options  therefor,
the  Administrator,  in the  exercise  of its sole  discretion,  may  permit the
exercise of any of the Options prior to consummation of such event, even if such
Options were not otherwise exercisable.

                  6.1.3  Time of  Option  Exercise.  Subject  to  Section  5 and
Section  6.3.4,  Options  granted  under  this  Plan  shall be  exercisable  (a)
immediately as of the effective date of the stock option agreement  granting the
Option,  or (b) in accordance with a schedule as may be set by the Administrator
(each such date on such schedule,  the "Vesting Base Date") and specified in the
written stock option agreement  relating to such Option.  In any case, no Option
shall be exercisable until a written stock option agreement in form satisfactory
to the Company is executed by the Company and the optionee.

                  6.1.4 Option Grant Date.  The date of grant of an Option under
this Plan shall be the date as of which the Administrator approves the grant.

                  6.1.5  Nontransferability  of Option  Rights.  Except with the
express written approval of the  Administrator  which approval the Administrator
is authorized to give only with respect to NQSOs,  no Option  granted under this
Plan shall be assignable  or otherwise  transferable  by the optionee  except by
will,  by the laws of  descent  and  distribution  or  pursuant  to a  qualified
domestic  relations order.  During the life of the optionee,  an Option shall be
exercisable only by the optionee.

                  6.1.6 Payment.  Except as provided below,  payment in full, in
cash,  shall be made for all  stock  purchased  at the time  written  notice  of
exercise of an Option is given to the Company, and proceeds of any payment shall
constitute general funds of the Company.  The Administrator,  in the exercise of
its  absolute  discretion,  may  authorize  any  one or  more  of the  following
additional methods of payment:

                        (a) Subject to the discretion of the  Administrator  and
the terms of the stock option  agreement  granting  the Option,  delivery by the
optionee of Shares  already  owned by the optionee for all or part of the Option
price,  provided  the fair  market  value  (determined  as set forth in  Section
6.1.10) of such Shares  being  delivered is equal on the date of exercise to the
Option  price,  or such portion  thereof as the optionee is authorized to pay by
delivery of such stock; and

                        (b)  Subject  to the  discretion  of the  Administrator,
through the  surrender  of Shares  then  issuable  upon  exercise of the Option,
provided the fair market value  (determined  as set forth in Section  6.1.10) of
such  Shares  is equal on the date of  exercise  to the  Option  price,  or such
portion thereof as the optionee is authorized to pay by surrender of such stock.

                  6.1.7 Termination of Employment.  If for any reason other than
death or permanent and total  disability,  an optionee  ceases to be employed by
the Company or any of its Affiliates (such event being called a  "Termination"),
Options held at the date of Termination (to the extent then  exercisable) may be
exercised  in whole or in part at any time  within  three  months of the date of
such  Termination,  or such other period of not less than 30 days after the date
of such  Termination  as is  specified  in the Option  Agreement or by amendment
thereof (but in no event after the Expiration Date); provided,  however, that if
such  exercise of the Option would result in  liability  for the optionee  under
Section 16(b) of the Exchange Act, then such  three-month  period  automatically
shall be  extended  until  the  tenth day  following  the last  date upon  which
optionee  has any  liability  under  Section  16(b)  (but in no event  after the
Expiration  Date).  If an  optionee  dies or  becomes  permanently  and  totally
disabled  (within the meaning of Section 22(e)(3) of the Code) while employed by
the  Company  or an  Affiliate  or within the  period  that the  Option

<PAGE>

remains  exercisable  after  Termination,  Options then held (to the extent then
exercisable)  may be exercised,  in whole or in part,  by the  optionee,  by the
optionee's  personal  representative  or by the  person  to whom the  Option  is
transferred  by  devise or the laws of  descent  and  distribution,  at any time
within  twelve  months after the death or twelve  months after the permanent and
total  disability of the optionee or any longer  period  specified in the Option
Agreement or by amendment  thereof (but in no event after the Expiration  Date).
For purposes of this Section 6.1.7,  "employment" includes service as a director
or as a consultant. For purposes of this Section 6.1.7, an optionee's employment
shall not be deemed to  terminate  by reason of sick  leave,  military  leave or
other leave of absence approved by the Administrator,  if the period of any such
leave  does not  exceed  90 days  or,  if  longer,  if the  optionee's  right to
reemployment by the Company or any Affiliate is guaranteed either  contractually
or by statute.

                  6.1.8  Withholding  and  Employment  Taxes.  At  the  time  of
exercise of an Option and as a condition  thereto,  or at such other time as the
amount of such obligations  becomes  determinable (the "Tax Date"), the optionee
shall remit to the Company in cash all applicable  federal and state withholding
and employment taxes.  Such obligation to remit may be satisfied,  if authorized
by  the  Administrator  in its  sole  discretion,  after  considering  any  tax,
accounting  and  financial  consequences,  by the  optionee's  (i) delivery of a
promissory note in the required amount on such terms as the Administrator  deems
appropriate,  (ii)  tendering  to the Company  previously  owned Shares or other
securities of the Company with a fair market value equal to the required amount,
or (iii) agreeing to have Shares (with a fair market value equal to the required
amount) which are acquired upon exercise of the Option withheld by the Company.

                  6.1.9 Other  Provisions.  Each Option  granted under this Plan
may contain such other terms,  provisions,  and conditions not inconsistent with
this Plan as may be determined by the Administrator,  and each ISO granted under
this Plan shall  include such  provisions  and  conditions  as are  necessary to
qualify the Option as an "incentive  stock option" within the meaning of Section
422 of the Code.

                  6.1.10  Determination  of Value. For purposes of the Plan, the
fair  market  value  of  Shares  or other  securities  of the  Company  shall be
determined as follows:

                        (a) Fair market value shall be the closing price of such
stock on the date before the date the value is to be determined on the principal
recognized  securities  exchange or recognized  securities  market on which such
stock is reported, but if selling prices are not reported, its fair market value
shall be the mean  between  the high bid and low asked  prices for such stock on
the date  before  the date the  value is to be  determined  (or if there  are no
quoted prices for such date,  then for the last preceding  business day on which
there were quoted prices).

                        (b) In the  absence  of an  established  market  for the
stock,  the fair market value  thereof  shall be determined in good faith by the
Administrator,  with reference to the Company's net worth,  prospective  earning
power,  dividend-paying  capacity,  and other  relevant  factors,  including the
goodwill of the Company,  the economic  outlook in the Company's  industry,  the
Company's position in the industry, the Company's management,  and the values of
stock of other corporations in the same or similar line of business.

                  6.1.11 Option Term.  Subject to Section 6.3.4, no Option shall
be exercisable more than 10 years after the date of grant, or such lesser period
of time as is set forth in the stock  option  agreement  (the end of the maximum
exercise period stated in the stock option agreement is referred to in this Plan
as the "Expiration Date").

         6.2 Terms and  Conditions  to Which  Only  NQSOs Are  Subject.  Options
granted  under this Plan which are  designated  as NQSOs shall be subject to the
following terms and conditions:

                  6.2.1 Exercise Price.

                        (a)  Except  as  set  forth  in  Section  6.2.1(b),  the
exercise  price of an NQSO shall be not less than 85% of the fair  market  value
(determined  in  accordance  with  Section  6.1.10) of the stock  subject to the
Option on the date of grant.

<PAGE>

                        (b) To the extent required by applicable laws, rules and
regulations,  the  exercise  price of a NQSO  granted  to any  person  who owns,
directly or by attribution  under the Code  (currently  Section  424(d)),  stock
possessing  more than ten  percent  of the total  combined  voting  power of all
classes  of  stock  of  the  Company  or  of  any   Affiliate  (a  "Ten  Percent
Shareholder")  shall in no  event be less  than  110% of the fair  market  value
(determined  in  accordance  with  Section  6.1.10) of the stock  covered by the
Option at the time the Option is granted.

         6.3 Terms  and  Conditions  to Which  Only  ISOs Are  Subject.  Options
granted  under  this Plan which are  designated  as ISOs shall be subject to the
following terms and conditions:

                  6.3.1 Exercise Price.

                        (a)  Except  as  set  forth  in  Section  6.3.1(b),  the
exercise  price of an ISO shall be determined in accordance  with the applicable
provisions  of the Code and shall in no event be less than the fair market value
(determined  in  accordance  with  Section  6.1.10) of the stock  covered by the
Option at the time the Option is granted.

                        (b) The  exercise  price  of an ISO  granted  to any Ten
Percent Shareholder shall in no event be less than 110% of the fair market value
(determined  in  accordance  with  Section  6.1.10) of the stock  covered by the
Option at the time the Option is granted.

                  6.3.2  Disqualifying   Dispositions.   If  stock  acquired  by
exercise  of  an  ISO  granted  pursuant  to  this  Plan  is  disposed  of  in a
"disqualifying  disposition"  within the  meaning of Section  422 of the Code (a
disposition  within two years from the date of grant of the Option or within one
year after the transfer of such stock on exercise of the Option),  the holder of
the stock  immediately  before the disposition shall promptly notify the Company
in writing of the date and terms of the disposition and shall provide such other
information regarding the Option as the Company may reasonably require.

                  6.3.3  Grant  Date.  If an ISO is granted in  anticipation  of
employment  as provided in Section  5(d),  the Option  shall be deemed  granted,
without  further  approval,  on the  date the  grantee  assumes  the  employment
relationship  forming the basis for such grant, and, in addition,  satisfies all
requirements of this Plan for Options granted on that date.

                  6.3.4 Term.  Notwithstanding Section 6.1.11, no ISO granted to
any Ten Percent  Shareholder shall be exercisable more than five years after the
date of grant.

7.       MANNER OF EXERCISE

         (a) An optionee wishing to exercise an Option shall give written notice
to the  Company at its  principal  executive  office,  to the  attention  of the
officer of the Company designated by the  Administrator,  accompanied by payment
of the exercise  price and  withholding  taxes as provided in Sections 6.1.6 and
6.1.8.  The date the Company  receives  written notice of an exercise  hereunder
accompanied by payment of the exercise price will be considered as the date such
Option was exercised.

         (b) Promptly  after receipt of written  notice of exercise of an Option
and the payments  called for by Section 7(a), the Company  shall,  without stock
issue or transfer taxes to the optionee or other person entitled to exercise the
Option,  deliver  to  the  optionee  or  such  other  person  a  certificate  or
certificates  for the  requisite  number  of shares of  stock.  An  optionee  or
permitted  transferee  of  the  Option  shall  not  have  any  privileges  as  a
shareholder  with respect to any shares of stock covered by the Option until the
date of issuance  (as  evidenced  by the  appropriate  entry on the books of the
Company or a duly authorized transfer agent) of such shares.

<PAGE>

8.       EMPLOYMENT OR CONSULTING RELATIONSHIP

         Nothing in this Plan or any Option granted  hereunder  shall  interfere
with or limit in any way the right of the Company or of any of its Affiliates to
terminate any  optionee's  employment or consulting at any time, nor confer upon
any  optionee  any right to  continue  in the employ of, or  consult  with,  the
Company or any of its Affiliates.

9.       CONDITIONS UPON ISSUANCE OF SHARES

         Shares shall not be issued pursuant to the exercise of an Option unless
the  exercise  of such  Option and the  issuance  and  delivery  of such  shares
pursuant  thereto shall comply with all relevant  provisions of law,  including,
without  limitation,  the  Securities  Act of 1933, as amended (the  "Securities
Act").

10.      NON-EXCLUSIVITY OF THE PLAN

         The  adoption  of the Plan  shall  not be  construed  as  creating  any
limitations  on  the  power  of  the  Company  to  adopt  such  other  incentive
arrangements  as it may  deem  desirable,  including,  without  limitation,  the
granting of stock options other than under the Plan.

11.      AMENDMENTS TO PLAN

         The Board may at any time amend,  alter,  suspend or  discontinue  this
Plan. Without the consent of an optionee, no amendment,  alteration,  suspension
or  discontinuance  may adversely affect  outstanding  Options except to conform
this Plan and ISOs  granted  under this Plan to the  requirements  of federal or
other tax laws relating to incentive  stock options.  No amendment,  alteration,
suspension or  discontinuance  shall  require  shareholder  approval  unless (a)
shareholder  approval is required to preserve  incentive stock option  treatment
for  federal  income tax  purposes  or (b) the Board  otherwise  concludes  that
shareholder approval is advisable.

12.      EFFECTIVE DATE OF PLAN; TERMINATION

         This Plan shall become effective upon adoption by the Board;  provided,
however, that no Option shall be exercisable unless and until written consent of
the  shareholders  of the Company,  or approval of  shareholders  of the Company
voting at a validly  called  shareholders'  meeting,  is obtained  within twelve
months after adoption by the Board. If such shareholder approval is not obtained
within  such  time,  Options  granted  hereunder  shall be of the same force and
effect as if such approval was obtained  except that all ISOs granted  hereunder
shall be treated as NQSOs.  Options may be granted and exercised under this Plan
only after  there has been  compliance  with all  applicable  federal  and state
securities laws. This Plan shall terminate within ten years from the date of its
adoption by the Board.<PAGE>

         "Amendment No. 6" means Amendment No. 6 to the Amended and Restated
         System Equipment Purchase Agreement dated as of February 4, 2004 by and
         between Owner and Vendor.

         1.2   Effective as of the Amendment No. 6 Effective Date, Section 8 of
the Contract shall be and is hereby amended by adding a new Section 8.4 as
follows:

"Section 8.4. RES Program.

         (a)   Subject to Vendor's prior receipt from Owner of (i) a Purchase
         Order for RES, (ii) payment of a deposit in the amount of [ *** ] (the
         "RES Deposit"), and (iii) the prorated quarterly fee payment for the
         first calendar quarter 2004, Vendor shall provide its RES program (the
         "RES Program") to Owner upon the terms and conditions set forth in that
         certain RES Statement of Work (the "RES SOW") attached as Attachment B
         to Amendment No. 6. [ *** ]

         (b)   Until the later to occur of (i) the Effective Date (as defined in
         Amendment No. 5) and (ii) Owner has re-established credit terms
         satisfactory to Vendor, Owner shall make each quarterly fee payment for
         RES (in addition to the payment of the RES Deposit) in advance, before
         the first Business Day of each calendar quarter for which Owner
         purchases RES.

         (c)   If at any time during the calendar quarter during which the RES
         Program is then in effect, the RES Deposit balance falls below the sum
         of [ *** ], within [***] business days of Vendor's written notice to
         Owner to that effect, Owner shall make payment to Vendor of an amount
         sufficient to restore the balance of the RES Deposit to the sum of [
         *** ] (the "Deposit Renewal Payment"). Owner's failure to pay any
         Deposit Renewal Payment as required by this subsection shall constitute
         a failure to pay an amount when due and owing under Section 24.7.1(a)
         of the Contract.

         (d)   RES Program Return Payment. In the event that the RES Program
         terminates as a result of Vendor's exercise of its remedies resulting
         from an Owner Event of Default or upon termination of the Contract (the
         "RES Termination Date"):

               (i)    Within [ *** ] after the RES Termination Date, Vendor
         shall refund to Owner the then existing balance of the RES Deposit less
         the sum of the following amounts:

                      a.     the aggregate amount of all unpaid applicable list
         prices, as set forth in Vendor's PCS Price Reference Guide in effect on
         the RES Termination Date (the "List Price Guide") for equipment that
         Vendor has delivered to Owner pursuant to the RES Program in exchange
         for old equipment (the "Exchange Equipment"), but which Exchange
         Equipment Owner has failed to return to Vendor in accordance with the
         RES SOW; and

                      b.     the aggregate amount of all unpaid restocking fees
         for each item of Exchange Equipment.

               (ii)   In the event that the foregoing calculation results in a
         negative balance, Vendor shall issue an invoice to Owner for any
         amounts due and owing to Vendor, and Owner shall pay such invoice
         within [ *** ]. The provisions of this Section 8.4 shall survive the
         termination of the Contract.

         herein, the RES Program shall terminate upon termination of the
         Contract."

         1.3   Effective as of the Amendment No. 6 Effective Date, Section 8 of
the Contract shall be and is hereby further amended by adding a new Section 8.5
as follows:

         "8.5  RS&R Program. (a) Subject to Owner's payment to Vendor of $[ ***]
         to be held in the Deposit Account (as defined in Attachment A to
         Amendment No. 6) in accordance with the terms and conditions set forth
         on such Attachment A and in the Contract, Vendor shall provide its RS&R
         program to Owner (the "RS&R Program") upon the terms and conditions set
         forth on Attachment A to Amendment No. 6 (retroactive to the Filing
         Date (as defined in Amendment No. 5)). Until the later to occur of (a)
         the Effective Date (as defined in Amendment No. 5) and (b) Owner has
         re-established credit terms satisfactory to Vendor, Owner shall
         maintain the Deposit Account in accordance with the Contract. Owner's
         failure to restore the balance of the Deposit Account within the
         Payment Period (as defined in Attachment A to Amendment No. 6) shall
         constitute a failure to pay an amount when due and owing under Section
         24.7.1(a) of the Contract. [ *** ]

         (b)   RS&R Program Return Payment. (i) In the event that the RS&R
         Program terminates as a result of Vendor's exercise of its remedies
         resulting from an Owner Event of Default or upon termination of the
         Contract (the "RS&R Termination Date"), within [ *** ] after the RS&R
         Termination Date, Vendor shall refund to Owner an amount equal to the
         then existing balance of the Deposit Account less the sum of all
         outstanding and unpaid charges for out-of-warranty Products, NTF and
         ATP Products that are shipped to Vendor under the RS&R Program (as such
         terms are defined in Attachment A to Amendment No. 6).

               (ii) In the event that the foregoing calculation results in a
         negative balance, Vendor shall issue an invoice to Owner for any amount
         due and owing to Vendor, and Owner shall pay such invoice within [ ***
         ]. The provisions of this Section 8.5 shall survive the termination of
         the Contract.

         (c)   Termination. Notwithstanding anything to the contrary set forth
         herein, the RS&R Program shall terminate upon termination of the

                            REPAIR SERVICE AND RETURN

ESTABLISHMENT OF ACCOUNT

Upon receipt by Vendor of $[ *** ] in collected funds from Owner, Vendor will
open a RS&R account for Owner, (the "Deposit Account"). The parties acknowledge
that Owner currently has the Deposit Account established for RS&R. Vendor will
continue to provide RS&R unless suspended or terminated pursuant to the
Contract. Upon the Effective Date (as such date is defined in Amendment No. 5 to
the Contract), Vendor may, upon request by Owner, and pending establishment of
new credit terms, in Vendor's sole and absolute discretion, consider releasing a
portion of the Deposit Account.

RS&R PROCESS UPON ESTABLISHMENT OF DEPOSIT ACCOUNT

         1)    Equipment that is not serviced by the RES Program shall be placed
               in Vendor's standard RS&R process for servicing. Vendor's receipt
               of Equipment shall constitute authorization to Vendor to
               determine whether the Equipment is under warranty. Equipment
               covered under warranty is repaired and returned at no cost to
               Owner pursuant to the applicable warranty provisions for such
               Equipment under the Contract. If the Equipment is not under
               warranty Vendor shall repair consistent with the charges included
               in Vendor's RS&R Price Guide. Should such repair charge not be
               listed in the RS&R Price Guide, Vendor will promptly submit to
               Owner a quote of the repair charges. Owner shall promptly direct
               Vendor as to whether such repairs are approved.

         2)    As indicated above, Equipment covered under warranty shall be
               repaired by Vendor and returned at no cost to Owner pursuant to
               the applicable warranty provisions for such Equipment.

         3)    Out of warranty Equipment is repaired and returned to Owner, with
               repair cost, tax and shipping charged against the Deposit
               Account, unless otherwise paid in advance by Owner. Repair costs
               and No Trouble Found /All Tests Passed costs are based on cost
               matrix that exists at the time of repair and will be provided to
               Owner and updated on a regular interval basis.

         4)    All No Trouble Found (NTF) or All Tests Passed (ATP) shall be
               charged against the Deposit Account, unless otherwise paid in
               advance by Owner.

         5)    If Equipment subject to the RS&R process cannot be repaired,
               Owner shall be notified and asked for directions as to further
               disposition by email within [ *** ] Business Days from receipt of
               the Equipment for servicing by Vendor. Such Equipment can either
               be returned to Owner or disposed of based on Owner's desire. If
               replacement of such Equipment is considered necessary by Owner,
               any price quote for a replacement Equipment shall be requested by
               Owner from the Vendor Account Team, and subject to the terms of
               the Contract.

         6)    At such time the Deposit Account balance is less than $[ *** ],
               Owner shall, within [ *** ] of Vendor's emailed request (the
               "Payment Period"), wire sufficient funds to restore the Deposit
               Account balance to $[ *** ]. Owner's failure to restore the
               Deposit Account balance within the Payment Period may result in
               suspension of all RS&R services pursuant to the terms of the
               Contract.

         7)    [ *** ]

         8)    The Deposit Account will be utilized only for RS&R of out of
               warranty Equipment, No Trouble Found (NTF) or All Test Passed
               (ATP) that are shipped to Vendor.

1.       MAINTENANCE DEFINITIONS

"Coverage Period" shall mean the times of day and the days of the week during
which RES will be provided hereunder and during the term of this RES program
which term shall be from the date Owner meets all the requirements of Section
2.6 below through March 31, 2005 or termination of the SEPA.

"Assistance Request" or "AR" shall mean an Owner-initiated request for
Maintenance Services to be performed. An AR will be considered valid when Vendor
acknowledges the request for assistance from Owner and confirms our
acknowledgement by providing Owner with an AR tracking number (call number,
ticket number). An AR may be initiated by Owner by telephone through the Vendor
designated technical support number(s) identified in this Agreement or through
the Vendor's web site ("Lucent.com"): http://www.lucent.com/support. Lucent.com
should not be used to initiate an AR when urgent assistance is needed. Requests
for assistance opened through Lucent.com are exempt from all response
requirements as defined in this statement of work ("SOW").

"RES" means the repair and exchange services to be provided by Vendor hereunder.

All terms used but not specifically defined herein shall have the same meaning
as set forth in that certain Amended and Restated System Equipment Purchase
Agreement, dated as of June 30, 2000, as amended (the "SEPA").

2.       REPAIR & EXCHANGE SERVICES
RES provides repair or exchange of Parts specifically listed in Exhibit 2
(attached to this Attachment B) entitled "Cricket RES Supported Parts List."
Such Exhibit 2 - Cricket RES Supported Parts List - is Vendor's standard Parts
list of FRU's (as defined below in Section 2.1) for all customers subscribing to
Vendor's current repair and exchange services program. The Parts listed in such
Exhibit 2 are the FRU's that are eligible for RES and are part of the Covered
Equipment listed in Exhibit 1 (attached to this Attachment B) entitled "Cricket
RES Covered Equipment." RES, when combined with Vendor's standard repair service
and return services (further described as "RS&R" as set forth in Attachment A to
Amendment No. 6 of the SEPA), will cover all of Owner's Equipment items
purchased from Vendor under the SEPA comprising Owner's Systems.

RES is priced on the basis of the Vendor-provided Equipment as identified in
Exhibit 1 hereto entitled Cricket RES Covered Equipment (the "Covered
Equipment"). Covered Equipment with quantities listed represents that Covered
Equipment contained in Owner's network of Systems as of the beginning of the
Coverage Period. The RES pricing in Section 2.5 below is subject to increase
should Owner add new incremental

Covered Equipment to Owner's network of Systems subsequent to the beginning of
the Coverage Period. Such increase in RES pricing shall be consistent with
Vendor's general pricing policy for all Vendor customers subscribing to RES. All
Parts that comprise the Covered Equipment owned by Owner will carry the same
Coverage Period and Response levels.

The RES program only provides for the repair or exchange of Parts and does not
include any accompanying technical or installation services of any kind.

2.1 RES DEFINITIONS

"Response Time" shall mean the elapsed time during the Coverage Period from the
time of issuance of the AR tracking number by Vendor until the Part is delivered
to Owner or until an attempt is made to deliver the Part per Owner's
instructions.

"Part", also referred to as a "Field Replaceable Unit" or "FRU", shall mean the
product assembly or subassembly of the Covered Equipment that can reasonably be
removed from service and/or installed without the use of uncommon tools and/or
methods. For the purpose of RES, Parts shall be specifically limited to those
described in Exhibit 2 - "Cricket RES Supported Parts List." Vendor shall have
sole authority for defining the composition of Parts to be exchanged or
repaired. Each type of Part will be assigned an identifier to distinguish it for
a particular function or purpose. This Part identifier will be used in
communication between Owner and Vendor when discussing Part(s) to be repaired or
exchanged. All exchanged Parts will be like-for-like, except where Vendor
determines that a replacement Part of a different type is fully compatible with
the Form, Fit, and Function of the defective unit being replaced. Each Part will
also have an assigned serial number to uniquely identify and distinguish it from
other Parts of similar type. Owner must always provide the Part reported as
suspected faulty and requested for exchange. In the event Owner has parts for
repair that are not included on the Exhibit 2 - "Cricket RES Supported Parts
List," Owner may request that Vendor add the part. If Vendor agrees to add the
part to the Cricket RES Supported Parts List, the added Part will be covered by
RES within [ *** ] days of the date added. Owner shall provide Vendor with as
much information about Parts as is reasonably available to Owner as requested by
Vendor, including, without limitation, the MSC locations or addresses of the
Parts.

Vendor will not have any components replaced and will not be physically or
materially altered in any way.

"Part Request" or "PR" shall mean that Vendor has authorized a Part to be
repaired or exchanged according to the terms of this Agreement. A Part Request
record is created after an Assistance Request is created. Each Assistance
Request may have more than one Part Request associated with it.

"Fit" means the suitability or readiness of a product for a particular
application, including environmental extremes, marginal parameters, physical and
signal compatibility with interfacing systems and surroundings, level of
performance, safety margins, reliability, maintainability and installability.

"Form" means the weight, density, chemical or product composition, size, shape,
structure, appearance, protocol, pattern, composition, configuration and
marking/identification of product and software.

Vendor will initiate a Part Request to be performed under the terms of this
Agreement only after (1) a Vendor technical support engineer determines a Part
to be suspected faulty, OR (2) Owner has successfully diagnosed and isolated a
faulty Part, AND (3) a Vendor technical support engineer acknowledges Owner's
analysis and identifies the suspected faulty Part identification number or code.

2.3 RES EXCLUSIONS

The following items and conditions (except for Pre-Existing Condition Parts) are
excluded from RES:

         -     Pre-existing conditions making the Part Defective prior to the
               RES Coverage Period, except that Owner and Vendor acknowledge
               that Owner currently has some Parts which already have defects
               and are considered "pre-existing" making the Part Defective prior
               to the beginning of the Coverage Period, but Vendor has agreed to
               not exclude such Parts provided that Owner shall provide Vendor
               with a list of all such currently Defective Parts within [ *** ]
               of the date on which Amendment No. 6 to the SEPA is executed by
               both parties or by February 6, 2004 which ever is earlier.
               Thereafter, Owner and Vendor will work to mutually agree on a
               not-to-exceed ("NTE") quantity of Defective Parts considered
               "pre-existing" to this RES Coverage Period (the "NTE Defective
               Parts"). Upon Owner's and Vendor's written agreement with respect
               to the quantity of NTE Defective Parts, Owner and Vendor will
               work to replace such NTE Defective Parts over the following [ ***
               ] period such that replacements will be prorated evenly and will
               not create undue hardship on either Owner or Vendor.

         -     Defects or malfunctions caused by: (1) actions or inactions of
               non-Vendor personnel; (2) failure to follow the manufacturer's
               installation, operation, or maintenance instructions and (3)
               failure of products following service not performed by Vendor.
               Vendor acknowledges that Owner will be performing most of the
               services to remove Defective Parts and install the new or
               repaired Parts.

         -     Defects or malfunctions that include: (1) modifications made by
               non-Vendor personnel; or (2) attachment of products not supported
               by Vendor.

         -     Passive and mounting hardware including, but not limited to,
               cables, cable assemblies, cords, brackets, bezels, face plates,
               adapters, panels, or labels.

2.4 ADVANCED EXCHANGE

Vendor will provide, upon receiving and accepting Owner ARs, a replacement Part
in advance of receiving a reported Defective Part from Owner. Vendor will
arrange for the delivery of replacement Part(s) to Owner's designated site
within the Response Time specified below in Subsection 2.4.1 and during the
Coverage Period as specified in this Agreement.

Owner may direct Vendor to deliver exchanged material to a location other than
the System Element Site, provided Owner identifies the alternate ship-to
location before the AR is accepted by Vendor. In such cases, Vendor will be
excused from its Response Time obligation, but shall still provide the
applicable Part replacement promptly. Owner is responsible for having personnel
at the System Element Site. Vendor shall be excused from its Response Time
obligation should Vendor's carrier attempt delivery and no Owner personnel is
available for receipt of the exchanged Part.

Upon receiving the replacement Part, Owner will return the reported Defective
Part to Vendor within [ *** ] days. Vendor will provide shipping instructions
and pre-paid shipping labels for this purpose. Owner will follow the shipping
instructions for returning Defective Parts to Vendor, and will use the return
label that Vendor or its authorized logistics agent has provided. Owner's
failure to materially (as is commercially reasonable) follow the return
instructions and/or use the provided return label will be treated by Vendor as
an unreturned Part.

Owner is responsible to include all relevant documentation, if any, with
returned Parts including failure description, diagnostic test results, or some
other indication suggesting that a Part was suspected to be faulty or in need of
replacement, and a reference to Vendor's assigned AR number.

Owner is responsible to provide adequate packing material to protect against a
reasonable risk of damage that would normally occur during shipping by common
carrier. If Owner fails to return the reported Defective Part to Vendor within [
*** ] days of Owner's receipt of the replacement Part, Owner agrees to pay
Vendor full list price for the advanced

Vendor provided packaging (packaging used for the advanced exchanged Part when
returning the Defective Part to Vendor). Should damage in transit occur the
parties will work together to resolve any damage issues based on, among other
things, which party had the risk of loss when such damage occurred. Vendor will
provide to Owner on a weekly basis a report of Defective Parts not received by
Vendor within [ *** ] calendar days of the date Owner received the replacement
Part from Vendor. Owner will be granted an extension of the [ *** ] day return
period referenced above if the weekly report is not provided to the Owner or if
the Part that needs to be returned in [ *** ] days is not shown as due to be
returned in the weekly report submitted to Owner for the week such Part is due.
Such extension shall be deemed to extend the otherwise applicable [ *** ] day
period to [ *** ] calendar days after Vendor submits the weekly report to Owner
that lists the applicable Part as due.

2.4.1 NEXT DAY ADVANCED EXCHANGE (AE-ND); RESPONSE TIME

Vendor will provide advanced exchange of Parts during the next calendar day
following an AR as determined by the time zone of the Part location during the
Coverage Period of 12:00:01 AM Sunday through 11:59:59 PM Saturday, including
holidays, provided that the AR is opened and accepted prior to 5:00 PM local
time as determined by the time zone of the equipment location. Assistance
Requests that are received and accepted after 5:00 PM will be considered
received on the following day. Parts that require custom configuration or
software installation will be shipped for delivery on the second business day
following the AR.

2.5 FEE SCHEDULE: The aggregate price for RES service for all the Systems is
USD$[ *** ] per calendar quarter for a period of 5 quarters, beginning January
1, 2004, and ending at midnight on March 31, 2005. The quarterly fee shall be
pro-rated on daily basis for the first quarter 2004 starting from the day Vendor
receives the first payment for RES. Annualized price is $[ *** ] and Total
Contract Value is $[ *** ]. Purchases of Covered Equipment not identified as
being in Owner's network as of the beginning of the Coverage Period (Covered
Equipment in Exhibit 1 with no quantities listed) may result in an incremental
increase for the RES program. Such increase in RES pricing will be consistent
with Vendor's general pricing policy for all such customers subscribing to RES.

After termination by Owner, the Maintenance Services may be subsequently
reinstated with the consent of Vendor and upon payment by Owner of Maintenance
Services fees for the period of time between the date of termination and the
date of reinstatement. The RTS Advantage NE/EMS is considered paid in full [ ***
]. All of the terms should apply accordingly.

the ability to submit and status ARs online. Lucent.com is used to deliver
certain items described below in the Software Maintenance section of this SOW.

2.2      Schedule/Time Frame

This section describes the performance objectives for RTS Advantage NE/EMS. The
performance objectives depend upon Severity Levels as defined below.

2.2.1    Severity Levels

                              COMMUNICATIONS, INC

Severity Levels are defined as the condition of the Maintained Product when
Owner submits an AR. Severity Levels are defined below.

SEVERITY LEVEL 1: THE MAINTAINED PRODUCT IS INOPERATIVE AND OWNER'S INABILITY TO
USE THE PRODUCT HAS A CRITICAL EFFECT ON OWNER'S OPERATIONS. THIS CONDITION IS
GENERALLY CHARACTERIZED BY COMPLETE SYSTEM FAILURE AND REQUIRES IMMEDIATE
CORRECTION. IN ADDITION, ANY CONDITION THAT MAY CRITICALLY IMPACT HUMAN SAFETY
IS CONSIDERED A SEVERITY LEVEL 1 PROBLEM.

SEVERITY LEVEL 2: THE MAINTAINED PRODUCT IS PARTIALLY INOPERATIVE BUT STILL
USABLE BY OWNER. THE INOPERATIVE PORTION OF THE PRODUCT SEVERELY RESTRICTS
OWNER'S OPERATIONS, BUT HAS A LESS CRITICAL EFFECT THAN A SEVERITY LEVEL 1
CONDITION.

SEVERITY LEVEL 3: THE MAINTAINED PRODUCT IS USABLE BY OWNER, BUT WITH LIMITED
FUNCTIONS. THIS CONDITION IS NOT CRITICAL AND DOES NOT SEVERELY RESTRICT OWNER'S
OVERALL OPERATIONS.

SEVERITY LEVEL 4: THE MAINTAINED PRODUCT IS USABLE AND THE CONDITION DOES NOT
MATERIALLY AFFECT OWNER'S OPERATIONS.

2.2.2    Respond, Restore and Resolve Performance Objectives

The performance objectives established by Vendor are measured from the time
Owner contacts Vendor's call receipt center ("CRC") by telephone with an AR.
Response times depend upon the initial Severity Level of the request as reported
by Owner to the CRC. (Vendor reserves the right to assign a higher or lower
Severity Level to a problem once it has verified the problem.) The objectives
for currently supported Maintained Products are outlined in the following
tables:

Objectives for matters attributable to covered third-party products are those
provided by the third-party vendor and are excluded from the timeframes
indicated above. . All third-party products (including Hardware and Software)
and their objectives for which Vendor has licensed to the Owner are listed in
Appendix B, if applicable. For OEM products made a part of Vendor Products and
provided by Vendor under the SEPA are covered in the response times above.

* Specific elements are covered in Appendix A.

2.2.3    Performance Objective Definitions

RESPOND MEANS A VENDOR SUBJECT MATTER EXPERT HAS CONTACTED OWNER REGARDING A
PARTICULAR AR.

RESTORE MEANS THAT THE PROBLEM IS REMEDIED SUFFICIENTLY TO RETURN THE PRODUCT OR
FEATURE TO OPERATIONAL STATUS. RESTORE MAY MEAN THAT A SOFTWARE FIX HAS BEEN
PROVIDED TO TEMPORARILY CORRECT THE PROBLEM, OR A WORKAROUND HAS BEEN
IMPLEMENTED.

RESOLVE MEANS THAT A PROBLEM RESOLUTION HAS BEEN PROVIDED AND THE AR HAS BEEN
CLOSED. THIS MAY OCCUR SIMULTANEOUSLY WITH RESTORE, UNLESS THE RESTORE IS BY
MEANS OF A WORKAROUND SUITABLE ONLY FOR TEMPORARY USE AND VENDOR DETERMINES THAT
A MORE SUITABLE PERMANENT SOLUTION CAN FEASIBLY BE PROVIDED.

If during or after the investigation of any problem, Vendor determines that
Vendor has already made available Software Patches, Software Updates, or
Software Upgrades that, if properly implemented, would have remedied the
problem, then Vendor will immediately advise Owner of the specifics and Vendor
shall be released from any obligations for such problem until Owner has
implemented the applicable items.

3.       SOFTWARE MAINTENANCE

The following software maintenance items are provided under RTS Advantage
NE/EMS:

3.1   Software Patches/Software Updates

                  BETWEEN LUCENT TECHNOLOGIES INC. AND CRICKET
                              COMMUNICATIONS, INC

Software Patches are minor modifications to the Maintained Product to address a
specific problem and help restore a Maintained Product. Software Updates are a
collection of Software Patches and are sometimes referred to as maintenance
releases. Software Updates are generally downloaded via an electronic interface
and do not contain any new or additional features beyond what was provided in
Owner's current software release.

3.2   Software Upgrades

Software Upgrades are releases making more substantial changes than Software
Updates. Software Upgrades may contain new features or the addition of enhanced
functionality to current products. Software Upgrades may also include provision
of third party software upgrades, as made available by the third party software
manufacturer, if the third party software is supported by Vendor and was
licensed to Owner by Vendor. Any Software Upgrades that may be provided by
Vendor under the RTS Advantage NE/EMS service are provided as available. Vendor
does not commit that any Software Upgrades will ultimately be released, made
generally available and therefore provided during the term that Owner subscribes
to the RTS Advantage NE/EMS service. Furthermore, Vendor does not warrant that
any specific features or functionality will be included in any Software Upgrades
that may be provided under the RTS Advantage service prior to the time that a
Software Upgrade is released and made generally available to all RTS Advantage
NE/EMS subscribers.

3.3   Distribution

Software Upgrades may be provided in one or more alternate formats including
network downloadable, CD, tape, etc., depending upon Vendor's determination of
the distribution manner appropriate for the individual product. For example, if
Vendor makes a Software Upgrade available via Web site access, then that is the
distribution method to be used for that Software Upgrade. If Vendor elects to
make multiple media alternatives available such as via the Vendor.com or on a
CD-ROM, and no distribution method is specified in the applicable agreement,
then Owner may elect which of the available distribution methods to use. In any
case, Vendor will work with the Owner to provide a commercially reasonable
alternative available for distribution to get the Owner's Systems upgraded as
soon as possible.

Software Patches, Software Updates and Software Upgrades, are provided together
with corresponding standard documentation, as available, in the same number of
licensed copies as indicated in the agreement under which the original software
was acquired.

3.4   License Terms

                  BETWEEN LUCENT TECHNOLOGIES INC. AND CRICKET
                              COMMUNICATIONS, INC

All software that is ultimately provided in connection with RTS Advantage NE/EMS
service, including without limitation Software Updates, Software Upgrades,
Software Patches or workarounds, is licensed subject to the same terms,
restrictions, and limitations as contained in the licenses under which the
original software was acquired.

4.       DISCONTINUED AVAILABILITY AND VERSION SUPPORT

The term "Version" as used in this SOW refers to Software Updates as well as
Software Upgrades.

Beginning on the day Owner has installed (loaded onto a computer) a new Version,
Vendor will support both the old Version and new Version concurrently for [ ***
] days. Upon completion of the installation of Software Update or Software
Upgrade, Owner agrees to destroy the original and all copies of the previous
Versions, which are in Owner's possession or control within [ *** ] days and, if
requested, certify such destruction to Vendor.

In case of discontinued availability ("DA") of any Maintained Product or
Version, RTS Advantage NE/EMS will continue to be available, subject to the
terms of this SOW, for such Maintained Product or Version for the period stated
in a DA notification provided to Owner, which period shall not be less than [
*** ] from the date of the DA notification ("the Transition Period"). During
such period, availability of new Software Patches and Software Updates shall be
subject to the software support policy of the applicable product family, under
which defect support for lower Severity Levels may be limited. Any renewal of
the Term of this SOW shall apply to such products only through the end of the
Transition Period, and charges relating to such products in any Renewal Term
invoice will be prorated accordingly.

5.       LAB SYSTEMS

RTS Advantage NE/EMS service is intended for Maintained Products deployed
commercially in a communications network. Coverage may be extended to Maintained
Products used in Owner's own lab for testing purposes before and during
commercial use in Owner's network if such lab use is identified on Form A.
Respond-only objectives will apply.

Support for products used in a lab environment or for testing or development
purposes other than as described above is not covered under this SOW.
