                                BROKER AGREEMENT

     THIS AGREEMENT is effective as of the 1st day of August, 2005 by and
between EPIXTAR INTERNATIONAL CONTACT CENTER GROUP, INC. ("EPIXTAR") a
corporation duly organized and existing under the laws of the State of Delaware
with offices located at 11900 Biscayne Blvd., Suite 700, Miami, FL 33181, and
DDM CONSULTING, INC., a corporation organized and existing under the laws of the
State of Virginia with offices located at 3612 Oval Drive, Alexandria, VA 22305
(hereinafter referred to as "Broker").

         WHEREAS, EPIXTAR is providing data and trade secrets on a confidential
basis to Broker for the purpose of development and/or sale of contact center
and/or BPO services ("Services") to its customers;

         WHEREAS, Broker is engaged in the referral of various Services programs
for businesses which are users (hereafter "Customers") of said services and,

         WHEREAS, Customer(s) is/are defined to be and is/are limited to only
those business relationships/divisions initially introduced to EPIXTAR by the
Broker. This definition does not include any other business
relationship/division within the customer's company that has had or will have a
relationship with either EPIXTAR or another Broker.

         WHEREAS, there is a potential that Broker will act as a Broker to the
Business for EPIXTAR and, pursuant thereto, will enjoy a position of trust
wherein Broker is made privy to special knowledge concerning the Business; and

         WHEREAS, EPIXTAR and Broker agree that it is in their mutual best
interests, since Broker will be occupying a position of trust with EPIXTAR, for
Broker to execute an agreement wherein Broker covenants not to utilize or
otherwise disclose any trade secrets, product sources, or other confidential
information related to the Business and wish to protect their rights with
respect to any such information disclosed.

         THEREFORE, in consideration of the mutual covenants herein, the Parties
agree as follows:

Fee Service

1.   Broker has the obligation to assist in submitting various Services
     proposals from prospective Customers to EPIXTAR and also has the obligation
     to assist in submitting EPIXTAR marketing materials and proposals to
     prospective Customers. Broker's obligation is to extend EPIXTAR a right of
     first refusal on any new business it obtains, or any new business from
     existing clients. EPIXTAR has the right, but not the obligation, to accept
     or reject any such assisted proposals, which are submitted to it by Broker.
     For the purposes of this Agreement, the term "Customer" excludes
     independent business entities of a prospective client's organization.
     Nothing in this Agreement shall prohibit EPIXTAR from marketing its
     Services to other Customer entities which have not been introduced by
     Broker.

2.   On award of business to EPIXTAR by a Customer introduced to EPIXTAR by
     Broker and accepted by EPIXTAR, Broker and EPIXTAR will execute an "award
     of business" form detailing the Customer name, program and EPIXTAR's
     acceptance of such program subject to the terms and conditions stated
     herein. Broker will assist in implementation, using information provided by
     Customers, various BPO services and/or teleservices programs to achieve
     Customers' and EPIXTAR's objectives. Broker will act as a sales
     representative and will use its best efforts to expand Customers' account
     usage of EPIXTAR services once business is established, and will be paid
     fees as stated hereafter.

3.   Prior to entering into any formal contract or agreement with a Customer,
     all aspects of EPIXTAR's contract approval policy must have been adhered
     to. The Broker is not authorized to sign any document which contractually
     commits EPIXTAR to performance criteria or other Service Level Agreements
     (SLA's). Contract pricing and SLA's submitted to Customers by Broker
     without appropriate approvals are a violation of EPIXTAR policy. This may
     cause the contract to be terminated and/or the immediate termination of any
     right to payment under this Agreement.

                                       1
<PAGE>

4.   Where a services contract is terminated or varied for any reason, EPIXTAR
     may be required to issue a credit against that contract. In those
     circumstances where a credit is issued, Broker will be debited the pro rata
     portion of his commission that is due back to the Customer, up to the
     entire contract if necessary.

5.   It is expressly understood that Broker represents that it has relationships
     with other companies in similar business as EPIXTAR, and that EPIXTAR may,
     at its option, now and hereafter retain the services of individuals or
     companies providing services similar to Broker, and that this Agreement
     between EPIXTAR and Broker is mutually non-exclusive.

Compensation

6.   Both EPIXTAR and Broker will individually agree upon each business
     opportunity. For each submission of a business proposal, the Parties agree
     to notify the other party in writing of any conflict or prior relationship
     with, or knowledge of, or claim to, that particular proposed Customer. On
     award of business from Customers presented by BROKER and accepted by
     EPIXTAR, EPIXTAR shall pay the following commission fees on collected
     revenue:

     Broker shall receive a fee in the amount of One Hundred Percent (100%) of
     the commission percentage above on all collected revenues generated by BPO
     and/or telemarketing production for the first twenty-four (24) months of
     the program; for the months twenty-five (25) through thirty-six (36),
     BROKER will receive a fee in the amount of Fifty Percent (50%) of the
     commission percentage above on all collected revenues generated the
     Services. The term "collected revenues" specifically excludes all expenses
     billed to a customer on a pass-through basis (including without limitation
     telecommunications charges and subcontracted technology) and commissions
     payable to third parties. In order for BROKER to qualify for and receive
     any compensation on collected revenues, an agreement between EPIXTAR and
     Customer must be executed during the term of this Agreement. No commissions
     will be paid to Broker on any program that fails to generate a minimum of
     Nineteen Dollars ($19.00) of revenue per hour for US based programs, or
     Eight Dollars ($8.00) for Philippine and offshore based programs, for the
     monthly average revenue per hour for that program. For purposes of this
     Agreement, "average monthly revenue per hour" shall mean total collected
     revenue divided by total production hours for that particular month.



Payment Terms

7.   EPIXTAR will directly pay to Broker all fees due Broker within thirty (30)
     days of receipt by EPIXTAR of a Customer's paid invoice statement*. EPIXTAR
     will provide Broker, on a monthly basis, with a copy of all Customer
     invoices for each program that Broker is entitled to receive payment upon.
     *Broker will be paid commissions on production beginning on the effective
     date of this Agreement (i.e. production occurring from August 1-August 31
     will be billed to a Customer and Broker will receive fees within 30 days of
     EPIXTAR's receipt of payment for such invoice; Broker will be paid
     commissions for the month of July 2005 within 30 days of receipt by EPIXTAR
     of Customer's paid invoice statement).

Term and Renewal

8.   The term of this Agreement shall be for a three (3) year period. The
     parties may agree to extend this Agreement by mutual, written agreement.
     Any and all commissions due and payable prior to the termination of this
     Agreement shall remain due and payable in accordance with the terms of this
     Agreement after said termination until such fees have been paid, i.e.,
     until such time as services for those Customer(s) referred by Broker and
     accepted by EPIXTAR have been terminated.

Confidential Information

9.   The term "Confidential Information" shall mean all information, data,
     know-how, customer lists, trade secrets, plans, strategies, models,
     processes, methods, procedures, inventions or ideas which are related to
     either party's Business.

Disclosure of Confidential Information

10.  Company recognizes and acknowledges that the list of Consultant's contacts,
     as it may exist from time to time, is a valuable, special and unique asset
     of Consultant. Except as contemplated by this Agreement, Company will not,
     during or after the term of this Agreement, use, disclose, divulge or in
     any other manner make available the list of Consultant's contacts, or any
     part thereof, to any person, firm, corporation, association or other entity
     for any reason or purpose whatsoever which directly or indirectly benefits
     Company or injures Consultant's relationships with such contacts. Neither
     party shall, without the express written consent of the other party,
     disclose or divulge the existence or terms of this Agreement with any other
     party (with the exception of each party's legal counsel and financial
     advisors).

                                       3
<PAGE>

11.  Without Consultant's involvement or express written consent, Company shall
     not, either directly or indirectly, as an individual, proprietor, partner,
     stockholder, creditor, consultant, employee, officer, agent,
     representative, investor or in any other capacity or manner whatsoever,
     contact, solicit, attempt to solicit, accept a commission for, or otherwise
     be involved in any transaction(s) with any person, firm, corporation, or
     other entity that Consultant at any time introduces to Company until such
     time as an agreement is reached between Company and said person, firm,
     corporation or other entity. At such time that an agreement is reached
     between Company and said person, firm, corporation or other entity, that
     person, firm, corporation or other entity shall cease to be a valuable,
     special and unique asset of Consultant and shall thereafter be a valuable,
     special and unique asset of Company. The foregoing shall not apply to any
     transaction that Company has entered into prior to the date of this
     Agreement.

12.  Both parties covenant not to utilize or otherwise disclose any Confidential
     Information to anyone else without the prior written consent of the other
     party. Broker will submit to any and all potential Customers any mutual
     confidentiality or similar agreements, which EPIXTAR may require such
     Customers to execute. This non-disclosure requirement shall survive the
     termination or expiration of this Agreement.

13.  Each party's Confidential Information will remain its property
     notwithstanding disclosure hereunder. Disclosure of Confidential
     Information hereunder shall not be deemed to constitute a grant by one
     party to the other, by implication or otherwise, nor shall either party
     have a right or license to the Confidential Information.

Return or Destruction of Confidential Information

14.  Upon written demand of one party to the other or upon termination of this
     Agreement, each party shall return or destroy (and certify such destruction
     to the other party in writing) all writings, materials, photographs,
     drawings, samples or models (including all copies or reproductions thereof)
     containing, disclosing or constituting the Confidential Information.

Non-Solicitation

15.  Broker agrees not to solicit, divert, appropriate or attempt to solicit,
     divert or appropriate, on his own account or for the account of others,
     directly or indirectly, the business relationship with any other Broker,
     producer, manufacturer or any other person or entity providing goods or
     services to EPIXTAR. EPIXTAR agrees not to solicit, divert, appropriate or
     attempt to solicit, divert or appropriate, on his own account or for the
     account of others, directly or indirectly, the business relationship with
     any other person or entity providing goods or services to Broker.

16.  Broker agrees not to solicit, divert, appropriate, hire away or attempt to
     solicit, divert, appropriate or hire away, on his own account or for the
     account of others, directly or indirectly, any person or entity employed by
     or acting as a consultant to EPIXTAR, or any past or current customers of
     EPIXTAR for a period of five (5) years from the date hereof. EPIXTAR agrees
     not to solicit, divert, appropriate, hire away or attempt to solicit,
     divert, appropriate or hire away, on its own account or for the account of
     others, directly or indirectly, any person or entity employed by or acting
     as a consultant to Broker, or any past or current customers of Broker for a
     period of five (5) years from the date hereof.

Equitable Remedies

17.  Each Party acknowledges that the unauthorized disclosure or use of
     Confidential Information will cause irreparable injury to a party for which
     money damages would be an inadequate remedy, and agrees, therefore, that
     equitable remedies are appropriate and should be granted to prohibit and
     prevent conduct which would constitute a violation of obligations to this
     Agreement. The Parties acknowledge that it would be very difficult or
     impossible to measure the damages resulting from a breach of this
     Agreement. They further acknowledge that the restrictions herein are
     reasonable and necessary for the protection of the Business and good will
     of each party and, by virtue of the circumstances of their Businesses, a
     violation of any such covenants will cause irreparable damage. Therefore,
     each party agrees that if one party violates any of the provisions of this
     Agreement, the aggrieved party shall be entitled to pursue both an ex parte
     preliminary injunction and a permanent injunction to be issued by any court
     of competent jurisdiction, restraining any violation of any or all of said
     covenants by the wrongdoing party or it's agents, employees, associates,
     affiliates or partners, either directly or indirectly, and such right to
     injunction shall be cumulative to and in addition to whatever other
     remedies the aggrieved party may have. The Parties agree that the aggrieved
     party shall be entitled to pursue injunctive relief without the posting of
     a bond and specific performance as remedies for any such breach. In the
     event the aggrieved party retains the services of any attorney to represent
     it in any action to enforce this Agreement, the wrongdoing party agrees to
     pay the aggrieved party's attorney's fees and court costs.

Indemnification

18.  While EPIXTAR is acting within the scope and intent of this Contract,
     Broker agrees to indemnify, hold harmless and defend EPIXTAR, its
     affiliates and each of their officers, directors, employees, shareholders,
     successors and assigns (hereafter referred to in this clause as EPIXTAR)
     from any claim, action, liability, loss, damage, and/or suit. This
     indemnity shall cover all attorneys' and paralegals' fees and costs
     incurred by EPIXTAR before and at trial and at all tribunal levels
     including any appeals, whether or not suit is instituted, and those
     incurred in seeking and establishing the right to be indemnified hereunder.

Waiver

19.  The failure of either party at any time to enforce any rights or remedy
     available to it under this Contract or otherwise with respect to any breach
     or failure by the other party shall not be construed to be a waiver of such
     right or remedy with respect to any other breach or failure by the other
     Party.

Severability

20.  In the event that provisions of or restrictions contained in this Contract
     are held by a court of competent jurisdiction to be invalid or
     unenforceable, and are not reformed by such court, the remaining provisions
     and restrictions contained in this Contract shall nevertheless continue to
     be valid and enforceable as though the invalid or unenforceable provisions
     or restrictions of this Contract had not been included.

Notices

     shall be given in writing by telegram, confirmed facsimile, or similar

Arbitration

23.  Any dispute arising out of or relating to this Agreement will be settled by
     arbitration to be conducted in accordance with the Judicial Arbitration and
     Mediation Services ("JAMS") Comprehensive Arbitration Rules. The Federal
     Arbitration Act, 9 U.S.C. Sections 1-16, not state law, will govern the
     arbitrability of disputes. This Agreement will otherwise be governed by the
     laws of the State of Florida without regard to its choice of law
     principles. The costs of the arbitration, including the arbitrator's fees,
     will be shared equally by the parties; provided, however, that each party
     will bear the cost of preparing and presenting its own claims and/or
     defenses (including its own attorney's fees). The venue for arbitration
     will be Miami-Dade County, Florida. A single arbitrator engaged in the
     practice of law, who is knowledgeable about the subject matter of this
     Agreement, will conduct the arbitration. The arbitrator is bound to apply
     and enforce the terms of this Agreement. The arbitrator's decision will be
     final, binding and enforceable in a court of competent jurisdiction. If a
     party is required to enforce compliance with this Section (including
     non-payment of an award), the non-complying party must reimburse all of the
     costs and expenses incurred by the party seeking such enforcement
     (including reasonable expenses incurred by the party seeking such
     enforcement (including reasonable attorney's fees). The parties agree that
     any and all disputes arising out of or related to this Agreement that shall
     be litigated to the extent permitted shall be heard exclusively in the
     United States District Court located in Miami, Florida and in no other
     state or federal court. The parties agree that all discovery in any
     litigation or arbitration of this Agreement shall occur only in Miami-Dade
     County, Florida.
