information  associated  in any way with Customer's use of XO's permit, approval
or  identification  number  and  shall  cooperate  with  XO if XO is required to
complete  any  reports  or respond to other inquiries associated with Customer's
use  of  XO's  permit,  approval  or  identification  number.

15.  INSURANCE.

     A.  Customer  shall  maintain  such  insurance, including through a blanket
policy,  as  will  fully protect both Customer and XO from any and all claims by
employees  of  Customer  under  the  Workers'  Compensation  Act  or  employer's
liability laws, including any employers' disability insurance laws, and from any
and  all  other  claims  of  whatever  kind  or nature for any and all damage to
property  or for personal injury, including death to anyone whomsoever, that may
arise  from  Customer's  acts  or  omissions,  including  without  limitation
installation,  operations,  maintenance  or  repair  services,  in or around the
Premises  by Customer or by anyone directly or indirectly engaged or employed by
Customer.  Customer  shall  provide XO with certificates evidencing the required
coverage  before  XO  begins  any installation work or services in or around the
Premises and indicating that XO shall be notified not less than thirty (30) days
prior  to  any  cancellation  or material change in any coverage. Such insurance
shall also name XO as an additional insured party under the coverage.

     B.  Customer's  General  Liability  Insurance  shall have a combined single
limit  of  $5,000,000  (including  any applicable primary and umbrella or excess
coverage).

     C.  Insurance  described in Paragraphs (A) and (B) of this Article 15 shall
be  maintained  by Customer throughout the term of this Agreement and any period
during  which  any claims arising from this Agreement are or may be outstanding.
Upon  Customer's  default  in  obtaining  or  delivering  any  such  policy  or
certificate of insurance or Customer's failure to pay the premiums therefore, XO
may  (but  shall  not  be  obligated  to) secure or pay the premium for any such
policy  and  charge  Customer the cost of such premium, which Customer agrees to
pay,  or XO may terminate this Agreement, in whole or in part, without liability
to  Customer.

16.  LIENS.  Customer  shall  not permit any mechanic's, material men's or other
liens  to  be  filed against all or any part of the Premises, Equipment Space or
Facilities,  by  reason  of  or  in  connection  with  any repairs, alterations,
improvements  or  other  work contracted for or undertaken by Customer. Customer
shall,  at  XO  request, provide XO with enforceable, conditional and final lien
releases (or other reasonable evidence demonstrating protection from liens) from
its  contractors  or other parties performing such work. XO shall have the right
at  all  reasonable times to post on the Premises and record any notices of non-
responsibility  which  it  deems necessary for protection from such Hens. If any
such  liens arc filed, Customer shall, at its sole cost, within thirty (30) days
after filing thereof, cause such lien to be released of record or bonded so that
it  no  longer  affects title to the Premises, Equipment Space or Facilities. If
Customer fails to cause such lien to be so released or bonded within such thirty
(30)  day  period, XO may, without waiving its rights and remedies based on such
breach,  and  without releasing Customer from any of its obligations, cause such
lien  to  be  released  or  bonded. Customer shall reimburse XO, within ten (10)
business  days  after  receipt  of invoice from XO, any sum paid by XO to obtain
such  bond  or  release.

17.  SUBCONTRACTORS.  Customer  may  subcontract  any portion of work within the
Premises  contemplated by this Agreement to any entity competent to perform such
work.  However,  Customer  must  obtain XO written approval before utilizing any
subcontractor to perform any activities within the Premises under this Agreement
and  provide  evidence  that  subcontractor  maintains  the  same  or additional
insurance  coverage  as  required  by Customer under this Agreement. In no event
shall such subcontract relieve Customer of any of its obligations or liabilities
under  this  Agreement.

18.  CONFIDENTIALITY.  The  Parties agree that all documentation and information
provided  by the other shall be used solely in connection with the installation,
operation, maintenance, and repair of the Equipment, that all such documentation
and information shall be deemed proprietary to the disclosing party and shall be
received  and  maintained  in  confidence.  Customer  acknowledges  that  all
information  about XO Customers and their operations is confidential and may not
be  disclosed  and  that Customer agrees it will not use any such information to
solicit  any  business  from  XO  Customers. Each Party shall preserve the other
Party's  confidential  information provided to it hereunder with the same degree
of care in protecting its own confidential or proprietary information, but in no
event  less  than  a  reasonable  standard  of  care  shall  be  used, and where
requested,  Customer  shall  execute and comply with the terms of an XO standard
General  Non-Disclosure  Agreement

19.  TERMINATION.

     A.  TERMINATION  FOR BREACH. XO may terminate the Agreement, in whole or in
part,  if  the  Customer  materially  breaches  any  warranty,  representation,
agreement, or obligation contained or referred to in the Agreement, or any other
agreement  with  XO,  provided  XO  has given Customer notice of such breach and
Customer  has  failed  to  cure  such  breach  within  a  thirty (30) day period
following notification, unless another cure period is noted in Paragraph B below
or such other applicable agreement; provided further, however, in the event of a
material  breach  by  Customer,  XO  may terminate the Agreement, in whole or in
part,  immediately  and  Customer  shall  be  subject  to  liability  for  early
termination  as  set  forth  in  Paragraph  D  below.

     B.   EVENTS  OF MATERIAL BREACH. Events of material breach by Customer of a
warranty,  agreement, representation, or obligation include, but are not limited

          facilities  at  the  Premises  by  the  installation,  operation,
          maintenance, replacement or repair of the Equipment, which breach must
          be  cured  within  twenty-four  (24)  hours.

          II.  Failure  by  Customer to pay the License Fee or any charges under

          III. Breach  by Customer of any material non-monetary provision of the
          Agreement  or  an  XO  service  order.

          V.   Customer's failure to complete all installation activities within

          VII. Cancellation/abandonment  of  a  site  pursuant  to a Collocation
          Schedule either prior to or after Customer has taken possession of the

          space.

          VIII.  Violation  of  the  confidentiality/press  release  provisions
          contained  herein,  which  violation  must  be  cured immediately upon
          notice.

     C.  COMMUNICATION  FACILITIES. Notwithstanding anything contained herein to
the  contrary,  in  the event XO is required to construct and/or acquire special
facilities  or  equipment  in  connection  with providing the Equipment Space to
Customer,  Customer  acknowledges  and  agrees  that  XO  may  therefore  incur
significant  costs  and  expenses in preparing such Equipment Space to Customer,
including but not limited to costs associated with constructing and/or acquiring
special facilities or equipment necessary for delivery of the Equipment Space to
Customer.  In  addition  to any other rights and remedies XO may have at law, in
equity  or  as  provided  herein,  Customer agrees that if Customer cancels this
Agreement  or  any  individual Collocation Schedule after signature but prior to
the  Service  Commencement  Date,  Customer shall reimburse XO for all costs and
expenses XO incurred in constructing and/or acquiring such special facilities or
equipment.

D.   EARLY  TERMINATION  CHARGE/BREACH.

     1.  PRIOR  TO  SERVICE  COMMENCEMENT.  In  addition to any other rights and
remedies  XO  may have at law or in equity, including those set forth in Section

                                        9

<PAGE>
cancels,  terminates  or  breaches  any  applicable  Collocation  Schedule after
execution  of  the  Collocation  Schedule  but prior to the Service Commencement
Date,  Customer  shall  pay XO an early termination charge in an amount equal to
two  (2)  months  of  the  License  Fee  set forth on the applicable Collocation
Schedule(s).

     2.  On  or After Service Commencement. Except as otherwise required by law,
if, after the Service Commencement Date, Customer: (a) commits and fails to cure
(to  the  extern  cure  is permitted herein) a material breach of the Agreement,
including  any  Collocation Schedule; or (b) Customer cancels or terminates this
Agreement  or any Collocation Schedule at any time before completion of the Term
or  any  renewal  Term, then XO may elect to pursue one or more of the following
courses  of  action,  as  applicable:  (i)  terminate  this  Agreement  or  any
Collocation  Schedule,  whereupon  all License Fees, including all non-recurring
charges,  for  the remaining Term are immediately due and payable, and terminate
any  related  service  order agreements, whereupon all early termination charges
set  forth  therein  are  also  due;  (ii)  take immediate appropriate action to
enforce  payment, including suspension or discontinuance of the use of or access

termination  of this Agreement, any Collocation Schedule or any related services

waive  XO's  right  to pursue any other available remedies. It is agreed that XO
damages  in  the  event  of  cancellation  or  termination shall be difficult or
impossible  to  ascertain.  The  provisions  of  this  Article  19 are intended,
therefore,  to  establish  liquidated damages in the event of such event and are
not  intended  as  a  penalty.

          for  automobiles in YPNT's name, medical expenses or insurance, mobile
          phone, etc so long as the aggregate does not exceed the amounts above.
Employee(s)  of  Company shall be offered participation in any stock option plan
approved  by the Board of Directors of YPNT that are offered to other executives
and employees, whether key or not during the term of this agreement. Any options
and  or  stock  obtained  pursuant to this plan shall also be held as collateral
under  the  terms  of  the  line  of  credit  above.

4.        Expense Reimbursement. Company shall be entitled to reimbursement from
     --------------------------
     YPNT for all "out of pocket" expenses relating to providing the services to
     YPNT  described  herein.

5.   Stock  Compensation.  In order to more clearly align the efforts of Company
     -------------------
     with  the  Shareholders  of YPNT and to reward the Company for its superior
     past  performance on behalf of YPNTs shareholders the Board of Directors of
     YPNT  deems  it  prudent  to  award  250,000  shares of its Common stock to
     Company  for  services  performed from August 19, 2002 through December 30,
     2002  (this  is  in  addition, to the 50,000 shares already issued to David
     lannini  also  relating  to that time period). This 250,000 share award was
     previously  authorized  by  the  Board and is just being included herein by
     reference.  That Stock is currently valued (as traded on the OTC Electronic
     Bulletin  Board  on  Friday  January  1st,  2003) at 6 cents per share. The
     accounting  for  such  compensation  shall  be in accordance with Generally
     Accepted  Accounting  Principles  and  as required by the SEC, YPNT further
     acknowledges  that  it will pay any Federal or State Incomes taxes that the
     Company  may  have  to  pay on this stock award as they may come due to the
     Company. This stock shall be so encumbered as part of the flex compensation
     below  and  as  part  of  the  customer  acquisition requirement. If YPNT's
     customer  count  does  not  exceed  225,000 customers within 12 months from
     January  1,  2003 then the stock is subject to forfiture on a prorata basis
     on the customer count actually obtained. For example; if there were 202,500
     customer  that would be 90% of Goal. So 10% of the stock would be forfitted
     back  to  YPNT..

6.   Guarantee  of  YPNT obligations. As an accommodation to YPNT the Company or
     -------------------------------
     any  of its employees may elect to provide personal or corporate guarantees
     for any indebtedness incurred by YPNT. If they so chose to do so by signing
     below YPNT hereby indemnifies those Employees of the Company or the Company
     itself  for  any  loss,  claim,  or

                         Executive Consulting Agreement
                          Mar & Associates/YP.Net, Inc.
                              September 20th, 2002
                                  Page 3 of 9

<PAGE>
     damages  suffered  by  the  Company  or  its  employees  by  way  of  this
     guarantee(s).

7.   Signing  of  Documents. As a further accommodation to YPNT the employees of
     ----------------------
     the  Company  agree  to  execute  documents,  SEC  Filings,  and  or  to be
     authorized  signers  on  YPNT's  Bank  or  Financial Accounts as needed. By
     signing below YPNT hereby agrees to indemnify the Company and its Employees
     or  Agents  for  any actions they may take on behalf of YPNT or any damages
     they  may  sustain  for  this  accommodation.

8.   Bonus  By  order  of the Board of Directors and as a condition of executing
     -----
     this  contract  a bonuses will be in the amount of $15,000 on September 30,
     2003  and  $ 21,000 on September 30, 2004 and 10% of annual salary for each
     Fiscal  year  thereafter  for  the  term of this contractFurther YPMT shall
     bonus  to  Company any Federal and/or State Income taxes that may be due by
     the  Company  for  this  bonus  when  Company  files it's income tax forms.

9.   Flex  Compensation.  YPNT  shall  make  available to the Company additional
     ----
     income,  which shall be called "Flex-Compensation", The maximum amount that
     can be immediately drawn upon shall be $15,000,00 (as a base in each fiscal
     year), except as modified below. However that base shall increase by 10% on
     each  12-month  anniversary  thereafter  during  the term of this contract.

     This  Flex Compensation is a part and parcel of the Compensation to be paid
     to  the  Company  by  YPNT,  However  as  part of the mutual accommodations
     between  the  parties Company agrees not to take all of the Compensation at
     one time but that in any event the Company is the final arbiter of when and
     if  YPNT  is  capable  of  paying  the  bonus  at  that  time.

     Sine  it  is  assumed  that the entire amount shall be taken in each fiscal
     year so for accounting purposes the Accountants shall accrue as an expense,
     in  the  case  of  YPNT and as income, in the case of Company 1/12lh of the
     total  amount  available  on  a monthly basis or the amount actually taken;
     whichever  is  greater.

     YPNT  is making this Flex Compensation available to the Company as a way to
     induce  the  Company to continue to perform services for the entire term of
     the  contract.  To  insure  that  the  Company  does  not  take  the  Flex
     Compensation  at  the  beginning  of  the  term and then resign the Company
     hereby  grants  to  YPNT  a  first  position lien right on all of the stock
     granted by the YPNT to either the Company or David lannini,. If the Company
     takes  the  Flex  Compensation,  and  resigns  it  has the choice of either

     returning  the  unused flex compensation for that fiscal year and retaining
     the  stock  or  returning  the  stock to the company. The Company and David
     lannini would not be allowed to sell, assign or further transfer this stock
     without  the  permission  of  the  Company,  which  permission shall not be
     unreasonable  withheld.  However,  because  of the valuable nature of these
     Services,  YPNT  would  be  obligated  to take title of these shares in the
     event  of  a  valid enforceable lien or judgment against Company that would
     encumber  these  shares and by signing below Company warrants that it would
     not  interfere. By signing below the Company and David lannini agree that a
     Security  Agreement  will  be  created  to  evidence  this  lien.

     -----------------

     offices  to  the  Company.  Said  monthly  lease  if assigned cannot exceed
     $350.00  per  month  till the end of the term of this agreement. Any amount
     above  $350.00  per  month  would  still by the responsibility of YPNT, The

     cancellation  in  the amount of $1,000,00 in year one, $500.00 in years two
     through  5,
