         This EXECUTIVE SEVERANCE AGREEMENT (the "Agreement"), is made as of
July 19, 2004 by and between ADVO, Inc. (the "Company") and Donald Schneider
(the "Executive").

RECITALS:

(as hereafter defined) exists;

continuity of its management and desires to establish certain severance benefits
for key executive officers of the Company, including the Executive, applicable
in the event of a Change of Control; and

         D. The Company wishes to aid in assuring that such executives are not
practically disabled from discharging their duties in respect of a proposed or
actual transaction involving a Change of Control.

         NOW, THEREFORE, the Company and the Executive agree as follows:

less than 80% of the then outstanding voting securities or, for any entity that
is not a corporation, at least 80% of the then-outstanding capital interests of
such entity and (ii) any additional entity which is deemed by action of the
Board to be an Affiliate for the purposes of this Agreement.

securities under any employee benefit plan of the Company, or any company owned,
directly or indirectly, by the stockholders of the Company immediately prior to
the occurrence with respect to which the evaluation is being made in
substantially the same proportions as their ownership of the common stock of the
Company) acquires securities of the Company and immediately thereafter is the
Beneficial Owner (except that a Person shall be deemed to be the Beneficial
Owner of all shares that any such Person has the right to acquire pursuant to
any agreement or arrangement or upon exercise of conversion rights, warrants or
options or otherwise, without regard to the sixty day period referred to in Rule
13d-3 under the Exchange Act), directly or indirectly, of securities of the
Company representing 30% or more of the combined voting power of the Company's
then outstanding securities (except that an acquisition of securities directly
from the Company shall not be deemed an acquisition for purposes of this clause
(i));

(ii) During any period of two consecutive years, individuals who at the
beginning of such period constitute the Board, and any new director (other than
a director designated by a person who has entered into an agreement with the
Company to effect a transaction described in clause (i), (iii) or (iv) of this
paragraph) whose election by the Board or nomination for election by the
Company's stockholders was approved by a vote of at least two-thirds of the
directors then still in office who either were directors at the beginning of the
two-year period or whose election or nomination for election was previously so
approved by excluding for this purpose any such new director whose initial
assumption of office occurs as a result of either an actual or threatened
election contest (as such terms as used in Rule 14a-11 of Regulation 14A
promulgated under the Exchange Act) or other actual or threatened solicitation
of proxies or consents by or on behalf of an individual, corporation,
partnership, group, associate or other entity or Person other than the Board,
cease for any reason to constitute at least a majority of the Board;

(iii) The consummation of a merger or consolidation of the Company with any
other entity, other than (i) a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving or resulting entity) more than 50% of
the combined voting power of the surviving or resulting entity outstanding
immediately after such merger or consolidation or (ii) a merger or consolidation
in which no premium is intended to be paid to any shareholder participating in
the merger or consolidation;

(iv) The stockholders of the Company approve a plan or agreement for the sale or
disposition of all or substantially all of the consolidated assets of the
Company (other than such a sale or disposition immediately after which such
assets will be owned directly or indirectly by the stockholders of the Company
in substantially the same proportions as their ownership of the common stock of
the Company immediately prior to such sale or disposition) in which case the
Board shall determine the effective date of the Change in Control resulting
therefrom; or

(v) any other event occurs which the Board determines, in its discretion, would
materially alter the structure or its ownership.

                                       2
<PAGE>

                  (e) "Cause" means that, prior to any Termination by the
Executive for Good Reason, the Executive shall have:

                           (i) committed an intentional act of fraud,
embezzlement, or theft in connection with the Executive's duties or in the
course of his employment with the Company;

                           (ii) committed intentional wrongful damage to
property of the Company; or

                           (iii) intentionally and wrongfully disclosed
confidential information of the Company; and any such act shall have been
materially harmful to the Company.

For the purposes of this Agreement, no act on the part of the Executive shall be
deemed "intentional" if it was due primarily to an error in judgment or
negligence, but shall be deemed "intentional" only if done by the Executive not
in good faith and without reasonable belief that the Executive's action or
omission was in the best interests of the Company.

                  (f) "Date of Termination" means the date of receipt of the
Notice of Termination or any later date specified therein, as the case may be;
provided, however, that if the Executive is Terminated by the Company other than
for Cause or for disability pursuant to Section 2(a) (ii), the Date of
Termination will be the date on which the Executive receives the Notice of
Termination from the Company; and provided further, if the Executive is
Terminated by reason of death or disability pursuant to Section 2(a)(i) or
2(a)(ii), the Date of Termination will be the last day of the month in which
occurs the date of death or the disability effective date, as the case may be.

                  (g) "Employee Benefits" means the prerequisites, benefits and
service credit for benefits as provided under the plans and programs maintained
by the Company, including, but not limited to, plans and programs which are
"employee benefit plans" under Section 3 (3) of the Employee Retirement Income
Security Act of 1974, as amended, and any amendment or successor, to such plans
or programs (whether insured, funded or unfunded).

                  (h) "Good Reason" means the occurrence of any of the events
listed in Sections 2(b)(i) through 2(b)(vii), inclusive.

                  (i) "Incentive Pay" means an annual amount equal to the
aggregate annual bonus, in addition to Base Pay, made or to be made in regard to
services rendered in any calendar year or performance period pursuant to any
bonus plan of the Company.

                  (j) "Notice of Termination" means a written notice which (i)
indicates the specific provision in this Agreement relied upon, (ii) sets forth
in reasonable detail the facts and circumstances claimed to provide a basis for
the Termination under the

                                        3
<PAGE>

provision so indicated, and (iii) if the effective date of the Termination is
other than the date of receipt of such notice, specifies the effective date of
Termination (which date will not be more than sixty (60) days after the giving
of such notice). The failure by the Executive to set forth in the Notice of
Termination any fact or circumstance which contributes to a showing that the
Executive is entitled to the benefits intended to be provided by this Agreement
will not constitute a waiver of any right of the Executive hereunder or
otherwise preclude the Executive from later asserting such fact or circumstance
in enforcing the Executive's rights hereunder.

                  (k) "Severance Period" means the period of time commencing on
the date of an occurrence of a Change of Control and continuing until the
earlier of (i) the date which is one and one-half years following the occurrence
of the Change of Control, and (ii) the Executive's death.

                  (l) "Subsidiary" means an entity, at least a majority of the
total voting power of the then-outstanding voting securities of which is held,
directly or indirectly, by the Company and/or one or more other Subsidiaries or,
for any entity that is not a corporation, at least a majority of the
then-outstanding capital interests of which is so held.

                  (m) "Term" means (A) the period commencing on the date hereof
and ending on the second anniversary of the date hereof; provided, however, that
commencing on the date one year after the date hereof, and on each annual
anniversary of such date (such date and each annual anniversary thereof shall be
hereinafter referred to as the "Renewal Date"), unless previously terminated,
the Term shall be automatically extended so as to terminate two years from such
Renewal Date, unless at least sixty (60) days prior to the Renewal Date the
Company shall give notice to the Executive that the Term shall not be so
extended, (B) if, prior to a Change of Control, for any reason the Executive is
Terminated or Terminates, thereupon without further action the Term shall be
deemed to have expired and this Agreement will immediately terminate and be of
no further effect, and (C) in the event of a Change of Control, the Term will,
without further action, be considered to terminate at the expiration of the
Severance Period.

                  (n) "Terminate" and correlative terms mean the termination of
the Executive's employment with the Company and any Affiliate or Subsidiary.

         2. Termination Following a Change of Control: (a) If, during the
Severance Period, the Executive is Terminated, the Executive will be entitled to
the benefits provided by Sections 3 and 4 unless such termination is by reason
of one or more of the following events:

                           (i)   The Executive's death;

                           (ii) The permanent and total disability of the
Executive as defined in any long term disability plan of the Company, applicable
to the Executive, as in effect immediately prior to the Change of Control;

                                        4
<PAGE>

                           (iii) Cause; or

                           (iv) The Executive's voluntary Termination in
circumstances in which Good Reason does not exist.

                  (b) In the event of the occurrence of a Change of Control, the
Executive may Terminate during the Severance Period with the right to severance
compensation as provided in Sections 3 and 4 upon the occurrence of one or more
of the following events (regardless of whether any other reason, other than
Cause as herein above provided, for Termination exists or has occurred,
including without limitation other employment):

                           (i) An adverse change in the nature or scope of the
authorities, powers, functions, responsibilities, or duties attached to the
position with the Company which the Executive held immediately prior to the
Change of Control;

                           (ii) A reduction in the Executive's Base Pay as in
effect immediately prior to any Change of Control, or as it may have been
increased from time to time thereafter;

                           (iii) Any failure by the Company to continue in
effect any plan or arrangement providing Incentive Pay in which the Executive is
participating at the time of a Change of Control (or any other plans or
arrangements providing substantially similar benefits) or the taking of any
action by the Company, any Affiliate or Subsidiary which would adversely affect
the Executive's participation in any such plan or arrangement or reduce the
Executive's benefits under any such plan or arrangement in a manner inconsistent
with the practices of the Company prior to the Change of Control;

                           (iv) Any failure by the Company to continue in effect
any Employee Benefits in which the Executive is participating at the time of a
Change of Control (or any other plans or arrangements providing the Executive
with substantially similar benefits) or the taking of any action by the Company,
an Affiliate or Subsidiary which would adversely affect the Executive's
participation in or materially reduce the Executive's benefits under any
Employee Benefits or deprive the Executive of any material fringe benefit
enjoyed by the Executive at the time of a Change of Control;

                           (v) The liquidation, dissolution, merger,
consolidation, or reorganization of the Company or transfer of all or
substantially all of its business and/or assets, unless the successor or
successors (by liquidation, merger, consolidation, reorganization, transfer, or
otherwise) to which all or a significant portion of its business and/or assets
have been transferred (directly or by operation of law) assumed all duties and
obligations of the Company under this Agreement pursuant to Section 9;

                           (vi) Without limiting the generality or effect of the
foregoing, any material breach of this Agreement by the Company or any
successors thereto; or

                                       5
<PAGE>

                           (vii) Any action by the Company which causes the
Executive's services to be performed at a location which is more than
thirty-five (35) miles from the location where the Executive was employed
immediately preceding the date of the Change of Control.

                  (c) Any Termination will be communicated by Notice of
Termination hereto given in accordance with Section 10 of this Agreement.

         3. Severance Compensation: (a) If, following the occurrence of a Change
of Control, the Executive is Terminated by the Company during the Severance
Period other than in the circumstances set forth in Section 2 (a) (i), 2 (a)
(ii), or 2 (a) (iii), or if the Executive Terminates for Good Reason:

                           (i) The Company will pay to the Executive in a lump
sum in cash within five (5) business days after the later of the date on which
the Company receives the determination of the Accounting Firm required in
Section 4 hereof or the Date of Termination the aggregate of the amount (the
"Severance Payment") equal to one times the sum of (A) the Executive's Base Pay
at the highest rate in effect at any time within the 90-day period preceding the
date the Notice of Termination was given or, if higher, at the highest rate in
effect at any time within the 90-day period preceding the date of the first
occurrence of a Change of Control, and (B) an amount equal to the greatest
amount of Incentive Pay received by the Executive during any calendar year or
portion thereof from and including the third calendar year prior to the first
occurrence of a Change of Control; and

                           (ii) For the period of one year from the Date of
Termination, the Executive shall be eligible for participation in and shall
receive all benefits under such benefit plans, practices, policies and programs
of the Company that provide medical, prescription dental, or life insurance
coverage, with the costs of such participation to be paid by the Company to the
same extent as prior to the Executive's Termination. In the event that such
continued participation is not allowed under the terms and provisions of such
plans or programs, then in lieu thereof, the Company shall acquire individual
insurance policies providing comparable coverage for the Executive; provided
that if any such individual coverage is unavailable, the Company shall pay to
the Executive an amount equal to the contributions that would have been made by
the Company for such coverage on the Executive's behalf if the Executive had
remained in the employ of the Company for the period referred to in the
preceding sentence.

                  (b) There will be no right of set-off or counter-claim in
respect of any claim, debt, or obligation against any payment to or benefit for
the Executive provided for in this Agreement.

                  (c) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided under this Agreement (including under this Section 3 or
Section 6) on a timely basis, the Company will pay interest on the amount or
value thereof at an annualized rate of interest equal to the so-called composite
"prime rate" as quoted from time to time during the relevant period in the
Northeast Edition of The Wall Street Journal. Such

                                       6
<PAGE>

interest will be payable as it accrues on demand. Any change in such prime rate
will be effective on and as of the date of such change.

                  (d) Notwithstanding any other provision hereof, the parties,
respective rights and obligations under this Section 3 and under Sections 4 and
6 will survive any termination or expiration of this Agreement following a
Change of Control or any Termination following a Change of Control for any
reason whatsoever.

         4. Excise and Other Taxes. The Executive shall bear all expense of, and
be solely responsible for, all federal, state, local or foreign taxes due with
respect to any payment received hereunder, including, without limitation, any
excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as
amended (the Code); provided, however, that all payments under this Agreement
shall be reduced to the extent necessary so that no portion thereof shall be
subject to the excise tax imposed by Section 4999 of the Code but only if, by
reason of such reduction, the net after-tax benefit received by the Executive
shall exceed the net after-tax benefit received by the Executive if no such
reduction was made. For purposes of this Section 4, "net after-tax benefit"
shall mean (i) the total of all payments and the value of all benefits which the
Executive receives or is then entitled to receive from the Company that would
constitute "parachute payments" within the meaning of Section 280G of the Code,
less (ii) the amount of all federal, state and local income taxes payable with
respect to the foregoing calculated at the maximum marginal income tax rate for
each year in which the foregoing shall be paid to the Executive (based on the
rate in effect for such year as set forth in the Code as in effect at the time
of the first payment of the foregoing), less (iii) the amount of excise taxes
imposed with respect to the payments and benefits described in (i) above by
Section 4999 of the Code. The foregoing determination will be made by a
nationally recognized accounting firm (the "Accounting Firm") selected by the
Executive and reasonably acceptable to the Company (which may be, but will not
be required to be, the Company's independent auditors). The Executive will
direct the Accounting Firm to submit its determination and detailed supporting
calculations to both the Company and the Executive within fifteen (15) days
after the Date of Termination. If the Accounting Firm determines that such
reduction is required by this Section 4, the Company shall pay such reduced
amount to the Executive in accordance with Section 3 (a). If the Accounting Firm
determines that no reduction is necessary under this Section 4, it will, at the
same time as it makes such determination, furnish the Company and the Executive
an opinion that the Executive will not be liable for any excise tax under
Section 4999 of the Code. The Company and the Executive will each provide the
Accounting Firm access to and copies of any books, records, and documents in the
possession of the Company or the Executive, as the case may be, reasonably
requested by the Accounting Firm, and otherwise cooperate with the Accounting
Firm in connection with the preparation and issuance of the determinations and
calculations contemplated by this Section 4. The fees and expenses of the
Accounting Firm for its services in connection with the determinations and
calculations contemplated by this Section 4 will be borne by the Company.

         5. No Mitigation Obligation: The Company hereby acknowledges that it
will be difficult, and may be impossible, for the Executive to find reasonably
comparable

                                       7
<PAGE>

employment following the Date of Termination. The payment of the severance
compensation by the Company to the Executive in accordance with the terms of
this Agreement will be liquidated damages, and the Executive will not be
required to mitigate the amount of any payment provided for in this Agreement by
seeking other employment or otherwise, nor will any profits, income, earnings,
or other benefits from any source whatsoever create any mitigation, offset,
reduction, or any other obligation on the part of the Executive hereunder or
otherwise.

         6. Legal Fees and Expenses: If the Company has failed to comply with
any of its obligations under this Agreement or in the event that the Company or
any other person takes or threatens to take any action to declare this Agreement
void or unenforceable, or institutes any litigation or other action or
proceeding designed to deny, or to recover from, the Executive the benefits
provided or intended to be provided to the Executive hereunder, the Company
irrevocably authorizes the Executive from time to time to retain counsel of the
Executive's choice, at the expense of the Company, to advise and represent the
Executive in connection with any such interpretation, enforcement, or defense,
including without limitation the initiation or defense of any litigation or
other legal action, whether by or against the Company or any member of the
Board, officer, stockholder, or other person or entity affiliated with the
Company, in any jurisdiction. The Company will pay and be solely financially
responsible for any and all attorneys' and related fees and expenses incurred by
the Executive in connection with such litigation.

         7. Employment Rights: Nothing expressed or implied in this Agreement
will create any right or duty on the part of the Company or the Executive to
have the Executive remain in the employment of the Company, or any Affiliate or
Subsidiary prior to or following any Change of Control.

         8. Withholding of Taxes: The Company may withhold from any amounts
payable under this Agreement all federal, state, city, or other taxes as the
Company is required to withhold pursuant to any law or government regulation or
ruling.

         9. Successors and Binding Agreement: (a) The Company will require any
successor (whether direct or indirect, by purchase, merger, consolidation,
reorganization, or otherwise) to all or substantially all of the business and/or
assets of the Company, by agreement in form and substance satisfactory to the
Executive, expressly to assume and agree to perform this agreement in the same
manner and to the same extent the Company would be required to perform if no
such succession had taken place. This Agreement will be binding upon and inure
to the benefit of the Company and any successor to the Company, including,
without limitation, any persons acquiring directly or indirectly all or
substantially all of the business and/or assets of the Company, whether by
purchase, merger, consolidation, reorganization, or otherwise (and such
successor will thereafter be deemed the "Company" for the purposes of this
Agreement), but will not otherwise be assignable, transferable, or delegable by
the Company.

                  (b) This Agreement will inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, and/or legatees.

                                       8
<PAGE>

                  (c) This Agreement is personal in nature and neither of the
parties hereto will, without the consent of the other, assign, transfer, or
delegate this Agreement or any rights or obligations hereunder except as
expressly provided in Sections 9 (a) and 9 (b). Without limiting the generality
or effect of the foregoing, the Executive's right to receive payments hereunder
will not be assignable, transferable, or delegable, whether by pledge, creation
of a security interest, or otherwise, other than by a transfer by will or by the
laws of descent and distribution and, in the event of any attempted assignment
or transfer contrary to this Section 9 (c), the Company will have no liability
to pay any amount so attempted to be assigned, transferred, or delegated.

         10. Notices: For all purposes of this Agreement, all communications,
including, without limitation, notices, consents, requests, or approvals,
required or permitted to be given hereunder will be in writing and will be
deemed to have been duly given when hand delivered or dispatched by electronic
facsimile transmission (with receipt thereof orally confirmed), or two business
days after having been mailed by United States registered or certified mail,
return receipt requested, postage prepaid, or one business day after having been
sent by a nationally recognized overnight courier service addressed to the
Company (to the attention of the General Counsel of the Company) at its
principal Executive office and to the Executive at the Executive's principal
residence, or to such other address as any party may have furnished to the other
in writing and in accordance herewith, except that notices of changes of address
will be effective only upon receipt.

         11. Governing Law: The validity, interpretation, construction, and
performance of this Agreement will be governed by and construed in accordance
with the substantive laws of the State of Connecticut, without giving effect to
the principles of conflict of laws of such State, to the extent not preempted by
applicable federal law.

         12. Validity: If any provision of this Agreement or the application of
any provision hereof to any person or circumstances is held invalid,
unenforceable, or otherwise illegal, the remainder of this Agreement and the
application of such provision to any other person or circumstances will not be
affected, and the provision so held to be invalid, unenforceable, or otherwise
illegal will be reformed to the extent (and only to the extent) necessary to
make it enforceable, valid, or legal.

         13. Non-Exclusivity of Rights: Nothing in this Agreement will prevent
or limit the Executive's present or future participation in any benefit, bonus,
incentive, or other plan or program provided by the Company or any Affiliate or
Subsidiary for which the Executive may qualify, nor will this Agreement in any
manner limit or otherwise affect such rights as the Executive may have under any
stock option or other agreements with the Company or any Affiliate or
Subsidiary. Amounts or benefits which are vested or which the Executive is
otherwise entitled to receive under any plan or program of the Company at or
subsequent to the Date of Termination will be payable in accordance with such
plan or program, except as otherwise expressly provided in this Agreement;
provided, however, that any amounts received by the Executive pursuant to this
Agreement shall be in lieu of any benefits which the Executive is entitled to
receive or

                                       9
<PAGE>

may become entitled to receive under any reduction-in-force or severance pay
plan or practice which the Company now has in effect or may hereafter put into
effect, any other benefits to which the Executive may be entitled under any
individual agreement of employment with the Company which would provide a
benefit to the Executive upon the occurrence of a Change of Control of the
Company, and any severance benefits required under federal or state law to be
paid to the Executive.

         14. Miscellaneous: (a) No provision of this Agreement may be modified,
waived, or discharged unless such waiver, modification, or discharge is agreed
to in writing signed by the Executive and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto or compliance with
any condition or provision of this Agreement to be performed by such other party
will be deemed a waiver of similar or dissimilar provisions or conditions at the
same or at any prior or subsequent time. No agreements or representations, oral
or otherwise, express or implied with respect to the subject matter hereof have
been made by either party which are not set forth expressly in this Agreement.
References to Sections are to references to Sections of this Agreement.

                  (b) The Executive and the Company acknowledge that this
Agreement supersedes any other agreement between them concerning the subject
matter hereof.

                  IN WITNESS WHEREOF, the parties have caused this Agreement to
be duly executed and delivered as of the date first above written.

Confidential Treatment. The portions of this exhibit that have been replaced

Commission and are the subject of an application for confidential treatment.

                               NINTH AMENDMENT TO
                            MASTER SERVICES AGREEMENT

      This Ninth Amendment ("Amendment") is effective as of July 1, 2004 (the
"Ninth Amendment Effective Date") and amends and supplements that certain Master
Services Agreement dated as of December 9, 1999 (the "Agreement") by and between
Valor Telecommunications Enterprises, LLC (formerly known as dba Communications,
LLC), a Delaware limited liability company ("Client") and ALLTEL Communications,
Inc., an Arkansas corporation (the successor to ALLTEL Information Services,
Inc.) ("ALLTEL") (each a "Party" and collectively, the "Parties").

      NOW, THEREFORE, in consideration of the mutual promises and agreements
contained herein, and other good and valuable considerations, the Parties agree
as follows:

1.    Term. The definition of "Expiration Date" as set forth in Section 1.1 (h)
of the Agreement is hereby replaced in its entirety with the following:

      "(h)  "Expiration Date" shall mean December 31, 2008."

2,    Access Line Charges. Section 2.1 of Exhibit E is hereby replaced in its
entirety with the following:

      "2.1  ACCESS LINE CHARGES.

      (a)   For each month during the Term, Client shall pay ALLTEL an amount
      (the "Access Line Charges" or "ALCs") equal to the greater of:

            (i)   the Minimum Monthly ALC (as determined in accordance with
      subsection (b) below), or

            (ii)  the actual number of Access Lines processed by ALLTEL
      multiplied by the applicable per Access Line Charge in subsection (c)
      below.

            For purposes of (ii) of this subsection (a), the actual number of
      Access Lines processed shall be determined as of the end of the month
      based on the Customer Access Line and Equipment Report generated through
      CAMS. In the event Client desires to utilize the ALLTEL System to bill its
      customers for services offered by Client without a corresponding Client
      Access Line which is billed through CAMS (e.g., out-of-territory ISP
      services, directory listings, directory advertising, etc.) (a "Non-Access
      Line Account"), Client shall so advise ALLTEL and ALLTEL will provide a
      proposal to

                                       1
<PAGE>

      Client to provide such Non-Access Line Account services, which proposal
      shall include any one-time and on-going charges of ALLTEL for such
      services. In the event Client desires to accept ALLTEL's proposal, the
      terms and conditions of such Non-Access Line Account services shall be
      reflected in an amendment to the Agreement. There shall be no additional
      Access Line Charges for services (such as ISP services, directory
      listings, directory advertising, etc.) associated with an Access Line. In
      addition, notwithstanding the foregoing, there shall be no additional
      Access Line Charges to continue utilizing the ALLTEL System to bill for
      Non-Access Line Account services that are being billed using the ALLTEL
      System as of the Ninth Amendment Effective Date; provided the number of
      Non-Access Line Accounts billed in this manner does not exceed [*****]% of
      the greater of the Minimum Number of Access Lines or the number of Access
      Lines then being processed by ALLTEL (however, if Client exceeds this
      threshold without agreeing on a rate per Non-Access Line Account for
      Non-Access Line Accounts services, Client shall pay $[*****] per
      Non-Access Line Account for such services until a revised rate is agreed
      upon).

      (b)   The "Minimum Monthly ALC" for the applicable month shall be as set
      forth in the following table:

<TABLE>

                                    MINIMUM NUMBER OF   MINIMUM MONTHLY

January, 2006 - December, 2006          [*****]          $[*****]
January, 2007 - December, 2007          [*****]          $[*****]
January, 2008 - December, 2008          [*****]          $[*****]
</TABLE>

      (c)   The applicable Access Line Charge for purposes of item (ii) of
      subsection (a) of this Section 2.1 above shall be as follows:

            (i)   for Access Lines up to [*****] in any month, the applicable
      per Access Line Charge shall be as follows:

                  (A)   for Access Lines processed in 2004, $[*****] per Access
                        Line;

                  (B)   for Access Lines processed in 2005, $[*****] per Access
                        Line;

                  (C)   for Access Lines processed in 2006, $[*****] per Access
                        Line;

                  (D)   for Access Lines processed in 2007, $[*****] per Access
                        Line;

                  (E)   for Access Lines processed in 2008, $[*****] per Access
                        Line;

            (ii)  for Access Lines in excess of [*****] in any month during the
                  Term of this Agreement, the incremental per Access Line Charge
                  shall be $[*****] per Access Line.

            For example, if in July, 2006, ALLTEL processes [*****] Access Lines
      for Client, the monthly Access Line Charge would be the greater of (A)
      $[*****] (which is

                                       2
      *****[CONFIDENTIAL]

      the Minimum Monthly ALC for July, 2006) or (B) $[*****] (which is the
      sum of (i) [*****] times $[*****] and (ii) [*****] times $[*****] for the
      [*****] Access Lines in excess of [*****]).

            (iii) The Access Line Charges shall continue to be adjusted for COLA
      pursuant to Section 8.1 of Exhibit E of the Agreement as amended by
      Section 6.1(b) of the Seventh Amendment to the Agreement.

            (iv)  All invoices issued by ALLTEL after the Ninth Amendment
      Effective Date for Services rendered prior to the Ninth Amendment
      Effective Date shall be at the charges set forth in this Section 2.

      (d)   ALLTEL shall invoice Client for Access Line Charges monthly, one
      month in arrears.

3.    Credits. ALLTEL shall provide Client with a credit of $[*****]. [*****]
Such credit shall beapplied by Client against the invoiced charges of ALLTEL in
December, 2004 (which invoice is for Services rendered by ALLTEL in
November, 2004).

4.    Conversion Matters.

      (a)   Kerrville Conversion.

            (i)   On or before March 31, 2005, Client shall Convert all of the
Client Access Lines known as the "Kerrville Access Lines" to the ALLTEL System,

            (a)   Client shall notify ALLTEL in writing ("Early Termination
                  Notice") of its intention to terminate the Agreement for
                  convenience at least nine (9) months prior to the proposed

                  subsections 19.5(b)(i) through (iv) within thirty (30) Days

                  prior to the date that is thirty (30) Days before the

                  accordance with Section 3.2 of the Agreement in as soon of a
                  time frame as is reasonably practicable. It is the intent of
                  the Parties that there shall exist no disputes or escrow
                  arrangements between the Parties as of the Termination
                  Completion Date.

            (d)   Notwithstanding delivery of an Early Termination Notice or
                  payment of fees due in accordance with this Section 19.5,
                  Client shall make all payments due and payable to ALLTEL for
                  Services rendered pursuant to this Agreement until the
                  Termination Completion Date."

            without the approval of Client, provided such acquisition or merger
            does not materially change the nature of the Services under this
            Agreement. If ALLTEL Corporation undergoes an ALLTEL Change in
            Control, ALLTEL shall, within one (1) business Day after the
            effective date of such change, provide written notice thereof to the
            other party. The acquirer or surviving entity shall agree in writing

      (e)   Except as provided in Section 22.2(d), ALLTEL shall not assign its
            rights or obligations under this Agreement to a non-Affiliate entity
            acquiring, directly or indirectly, control of ALLTEL or an ALLTEL
            Affiliate to which this Agreement has been assigned, a non-Affiliate
            entity into which ALLTEL or an ALLTEL Affiliate to which this
            Agreement has been assigned is merged, or a non-Affiliate entity
            acquiring all or substantially all of the assets of ALLTEL or an
            ALLTEL Affiliate to which this Agreement has been assigned, without
            the approval of Client, which Client may withhold in its sole
            discretion.

      (f)   All obligations and duties of any party under this Agreement shall
            be binding on all successors in interest and permitted assigns of
            such party.

      (g)   If the other party consents to the Assignment, the proposed assignee
            or transferee shall, upon completion of the Assignment,
            automatically succeed to the corresponding rights, interests, and
            obligations of the assigning and transferring party and shall be a
            successor of such party for purposes of this Agreement."

                  (provided that, if Client has given ALLTEL reasonable advance
                  notice of such reprioritization, ALLTEL has notified Client in
                  advance in writing that such reprioritization will cause
                  ALLTEL to miss such Service Level); or

            (c)   Circumstances that excuse performance in connection with a
                  Force Majeure Event as specified in the Agreement.

      1.6   MEASURING TOOLS. ALLTEL will select and use monitoring tools

            Service Levels. If the tool(s) selected by ALLTEL is not sufficient
            to measure and report valid performance data, ALLTEL shall promptly
            correct or replace such monitoring tools at no additional cost to
            Client. If Client asks

                                      B-3

***** [CONFIDENTIAL]
<PAGE>

            ALLTEL to use a new or different monitoring tool for any other
            reason, ALLTEL will comply with Client's request so long as such
            request does not require ALLTEL to incur any out-of-pocket expense
            or to provide additional hardware, software or personnel resources
            to acquire, maintain and operate such tools. In the event ALLTEL
            will incur out-of-pocket expense or must provide additional

            operate such tools, ALLTEL will acquire and utilize such tools
            provided that Client agrees to reimburse ALLTEL for any
            out-of-pocket expenses incurred and to compensate ALLTEL for any
            additional hardware, software or personnel resources required, in
            each case whether incurred as a one-time expense or as an on-going
            basis, for the use and operation of such tool. ALLTEL's charges for
            acquisition and utilization of a new tool requested by Client shall
            be subject to Client's prior approval of such charges. In the event
            Client does not approve ALLTEL's charges, ALLTEL shall not be
            obligated to provide such requested tool.

      1.7   SERVICE LEVEL CREDITS.

            (a)   Service Level Credits. In the event of a Service Level
                  Failure, and such failure is not excused as provided in
                  Section 1.5, ALLTEL shall accrue a Service Level Credit to
                  Client as follows:

                  (i)   For each Service Level Failure, a Service Level Credit
                        that will be computed in accordance with the following
                        formula:

                        Service Level Credit = A x B

                        Where:

                        A = [*****]

                        B = [*****]

                  (ii)  If more than one Service Level Failure has occurred in a
                        single month the sum of the corresponding Service Level
                        Credits shall be accrued by ALLTEL.

                  (iii) ALLTEL shall notify Client in writing if Client becomes
                        entitled to a Service Level Credit, which notice shall
                        be provided monthly and shall describe the Service Level
                        Failure(s). Except as provided in Sections 2.6(c) and
                        2.10, the total Service Level Credits for Service Level
                        Failure(s) occurring each month shall appear as a credit
                        on the invoice that contains Access Line Charges for the
                        month during which the Service Level Failure(s) giving
                        rise to such Service

                                      B-4

*****[CONFIDENTIAL]
<PAGE>

                        Level Credits occurred (e.g., the amount of Service
                        Level Credits to be credited with respect to Service
                        Level Failures occurring in August shall be set forth in
                        the invoice for the August Access Line Charges issued in
                        September).

            (b)   Earnback. ALLTEL shall have the opportunity to earn back
                  Service Level Credits as described in this Section 1.7(b). If
                  ALLTEL meets or exceeds the Service Level for [*****] which
                  such Service Level Credit was assessed for such Service Level,
                  then ALLTEL may invoice Client for the amount of such Service
                  Level Credit on its next monthly invoice ("Earnback Credit").

            (c)   Single Incident/Multiple Failures. If a single incident or
                  event in any Measurement Period results in the failure of
                  ALLTEL to meet more than one Service Level, [*****]

            (d)   Remedies. Under no circumstances shall the imposition of
                  Service Level Credits be construed as Client's sole or
                  exclusive remedy for any Service Level Failure. [*****]

      1.8   CHANGE MANAGEMENT PROCESS. New Service Levels may be added or
            replaced, or existing Service Levels may be modified or deleted,
            through the process set forth in this Section 1.8, in order to
            achieve a fair, reasonable, attainable, accurate, meaningful, and
            consistent measurement of ALLTEL's performance of the Services.

            (a)   Trigger Events. Events or changes that significantly affect
                  Client requirements or ALLTEL's delivery of Services could
                  trigger the need to delete or modify existing or add new
                  Service Levels. Such events and changes include the Parties
                  planning process, changes in Client's business (e.g., business
                  requirements, acquisitions, divestitures, changes in volumes),
                  additions of new Services, elimination of Services, regulatory
                  requirements, audit requirements or emerging technology. The

                  completeness.

            (b)   Service Level Agreement Change Assessment. Upon identifying
                  the need to add, delete or modify a Service Level, Client or
                  ALLTEL shall prepare a written analysis that supports such
                  modification, addition or deletion (a "Service Level Change
                  Proposal") and submit it to the ALLTEL Account Manager or
                  Client Project Manager, as applicable. The Parties shall then
                  review the Service Level Change Proposal and the receiving
                  Party shall have forty-five (45) Days to respond with an
                  assessment of the ramifications of the request (i.e. cost
                  impacts, business ramifications, etc.). All Service Level
                  Change Proposals must be mutually agreed upon (and agreement
                  may not be unreasonably withheld conditioned, or delayed by
                  either Party) before any Service Levels are added, deleted or
                  modified and shall be prioritized in accordance with the
                  Change Management Process described in Section 11 of the
                  Agreement. If new Service Levels are added or existing Service
                  Levels modified, the Parties agree that [*****].

      instance of a Service Level Failure and there shall be no further Service
      Level Credits for any other Service Level Failures that month for
      Availability. In the event of a Service Level Failure for any single
      System or Database, ALLTEL may not earn an Earnback Credit for that month
      even if the Service Level has been achieved on an aggregate basis.

      2.6   BILLING ACCURACY.

      (a)   General. Subject to the Exclusions set forth in Section 1.5 of this
Exhibit F, ALLTEL shall use its reasonable best efforts to maintain Billing
Accuracy as to meet or exceed the Service Level set forth in this Section 2.6.

      (b)   Measurement. The Actual Performance for Billing Accuracy shall be
calculated on a calendar month basis in accordance with the following formula
and expressed as a percentage:

            Billing Accuracy = ((Total Number of Accounts billed during a month
            - Bills in Error) / Total number of Accounts billed during a month)
            * 100.

      Client shall, as part of its bill verification process, verify at least
[*****]% of bills per cycle during each Measurement Period. Client shall perform
such bill verification in good faith and in a commercially reasonable manner.
However, if Client performs such bill verification in good faith and in a
commercially reasonable manner and Client nonetheless fails to detect an ALLTEL
Error, such failure shall not relieve ALLTEL of responsibility for such ALLTEL
Error for purposes of this Service Level, even if Client arguably should have
detected such error.

      For purposes of this Section 2.6, the termination trigger specified in
subpart (ii) of Section 1.9 shall be replaced with the following: "there are
Service Level Failures attributable to the same root cause in [*****],"

      (c)   Definitions. For purposes of this Section 2.6:

      "AGREED PARAMETERS" means taxes, ASOC and toll rating, optional calling
plans, other charges and credits, proration calculations, unreadable information
or bill truncation and subtotal and total bill amounts, and such other
parameters as may be mutually agreed upon in writing by the Parties.

      "ALLTEL ERRORS" means billing errors within the Agreed Parameters that are
identified within 30 days after the mailing of the Bills in Error, and that
directly result from the action or omission of ALLTEL. ALLTEL Errors shall not
include the following:

      (i)   errors resulting from ALLTEL complying with specifications or
            instructions received from Client;

      (ii)  errors detected by Client in bill verification process, unless
            Client informs ALLTEL of such error by promptly opening a Class A
            Incident, Client requests that it be corrected prior to the issuance
            of the bill and ALLTEL fails to correct such error prior to issuance
            of the bill;

      (iii) errors detected that were signed off by Client in quality assurance;

      (iv)  errors in data received from Client-authorized third parties, such
            as AT&T; or

      (v)   erroneous table entries made by Client;

                                      B-11
***** [CONFIDENTIAL]
<PAGE>

      (vi)  errors in data controlled by Client, such as Table Administration.

Billing Accuracy shall be reported in the Service Level report after the 30-day
period for the identification of ALLTEL Errors. Thus, for example, for bills
issued in May, ALLTEL Errors may be identified in the period ending June 30, and
Billing Accuracy will then be reported in the Service Level report delivered in
July.

      "BILLS IN ERROR" means the total number of bills issued during the
Measurement Period that contain ALLTEL Errors.

            (c)   Service Levels. The Service Level and Credit Percentage for
Billing Accuracy are as follows:

</TABLE>

      (d)   Effective Date. ALLTEL shall begin measuring and reporting Billing
Accuracy in accordance with this Section 2.6 on the Ninth Amendment Effective
Date. ALLTEL shall use reasonable best efforts to meet the Billing Accuracy
Service Level beginning on such date. However, ALLTEL shall not be subject to
the imposition of Service Level Credits for any failure to meet the Billing
Accuracy Service Level during the nine (9) months immediately following the
Ninth Amendment Effective Date, nor shall the provisions of Section 1.9 (as
amended in the next paragraph) apply during such nine (9) month period. During
that period, ALLTEL and Client shall work cooperatively to identify and
implement any changes required for ALLTEL to meet the Billing Accuracy Service
Level. As part of such effort, the Parties shall work cooperatively to identify
and, subject to Client's reasonable approval, implement measures to improve the
bill verification process of Client.

      If, after measuring Billing Accuracy performance for three (3) months, the
Parties conclude that ALLTEL, despite using reasonable best efforts, is unable
to meet this Service Level, the Parties shall develop and implement a corrective
action plan to (i) identify the root cause(s) of such inability to meet the
Billing Accuracy Service Level and (ii) implement any additional changes that
may be required for ALLTEL to meet the Billing Accuracy Service Level.

      2.7   BILLING TIMELINESS - END USER BILLING

            (a)   General. Subject to the Exclusions set forth in Section 1.5 of

            (c)   Measurements. Incident Management shall be measured for each
Measurement Period as follows:

                  (1)   Resolve or Resolution. The time to resolve an incident
shall be calculated as the time between when the incident is detected by ALLTEL
or reported by Client to ALLTEL and when the incident is "Resolved". An incident
shall be deemed to have been Resolved when service is restored in all material
respects and the Client is able to again perform its business functions in a
commercially reasonable manner. A Resolution can be accomplished with a
reasonable workaround. For purposes of this provision, a Class-A Incident is
Resolved when a workaround is in place to make it a Class-B Incident; provided
that the time to resolve

                                      B-14

<PAGE>

such Class-B Incident shall include the time during which the Incident was a
Class-A. The same shall be true for the Resolution of a Class-B Incident by
moving such Incident into a Class-C Incident.

                  (2)   The Average Resolution Time for Class-A Incidents shall
be calculated in days for each Measurement Period as follows:

            Class-A Incident Average Resolution Time = (Sigma) Time period to
            Resolve each Class-A Incident / Total number of Class-A Incidents
            Resolved during the Measurement Period.

                  In the event there are zero (0) Class-A Incidents reported in
