                            INFORMATION TECHNOLOGY SYSTEMS USAGE AND SERVICES AGREEMENT

         THIS INFORMATION TECHNOLOGY SYSTEMS USAGE AND SERVICES AGREEMENT (this
"Agreement") is entered into on September 1, 2004 by and between AF Services,
Inc., a Delaware corporation ("AF Services"), and eCOST.com, Inc., a Delaware
corporation ("eCOST").

         WHEREAS, eCOST obtains certain information technology and support services from AF Services;

         WHEREAS, eCOST is considering an initial public offering of its Common Stock ("IPO"); and
                                                                                        ---

         WHEREAS, eCOST desires to continue to obtain certain information
technology and support services from AF Services, and AF Services desires to
continue to provide such services following the IPO as more fully set forth
herein.

         NOW, THEREFORE, for and in consideration of the promises and the
obligations undertaken by the parties pursuant hereto, and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, AF Services and eCOST hereby agree as follows:
ARTICLE I

                        ENGAGEMENT OF AF SERVICES; duties

1.1 Engagement. Effective as of the closing date of the IPO (the "Effective
Date"), eCOST hereby retains AF Services to perform the information technology
and support services set forth on Exhibit A attached hereto, including such
services as may be related, ancillary, or necessary to perform such services
(each, a "Service", and collectively, the "Services").

1.2      Duties and Rights.

(a) AF Services Obligations.

(i) AF Services hereby covenants and agrees that it shall, during the term of
  this Agreement, perform the Services. AF Services covenants and agrees that it
  shall maintain accurate records and accounts of all transactions, data, files
  and information relating to the Services performed pursuant to this Agreement.
  Such records and accounts shall contain such information as would normally be
  examined by an independent accountant in performing a complete audit pursuant
  to United States generally accepted auditing standards for the purpose of
  certifying financial statements, and as would normally be required by a
  government taxing authority in order to verify provision of the Services.

(ii) AF Services shall perform the Services pursuant to this Agreement in a
  manner and at a level of service substantially similar to that provided by AF
  Services to eCOST prior to the date hereof and shall exercise the same care
  and skill as it exercises in performing similar services for other
  subsidiaries of PC Mall. In the event AF Services engages third parties to
  perform one or more Services under the supervision of AF Services pursuant to
  Section 1.2(c), AF Services shall cause such third parties to perform such
  Service under the same applicable performance standard.

(b) eCOST Obligations. eCOST hereby covenants and agrees that it shall pay AF
  Services for Services in accordance with Article III. eCOST further covenants
  and agrees that it shall provide AF Services with all documents and
  information necessary for AF Services to perform the Services pursuant to this
  Agreement. To the extent required, eCOST shall authorize AF Services to
  perform such actions as may be necessary for the performance of the Services.

(c) Right to Subcontract. In the performance of its obligations hereunder, AF
  Services shall have the right, in its sole discretion, to subcontract its
  rights and responsibilities to any third party, provided that AF Services
  shall remain responsible for the performance of any such third party.

(d) No Additional Resources. Unless otherwise agreed in writing, AF Services
  shall not be required to perform the Services at a level that is substantially
  greater than the level of use required by eCOST immediately prior to the
  Effective Date. Without limiting the foregoing, in connection with the
  performance of the Services, in no event shall AF Services be required to hire
  any additional employees, maintain the employment of any specific employee, or
  purchase, lease or license any additional equipment or intellectual property.

1.3 Independent Contractors. The relationship of AF Services and eCOST
established by this Agreement is that of independent contractors, and nothing
contained in this Agreement shall be construed to (a) constitute the parties as
partners, joint venturers, co-owners or otherwise as participants in a joint or
common undertaking; (b) create the relationship of principal and agent between
the parties; (c) prevent AF Services from entering into any other business; or
(d) allow AF Services to create or assume obligations on behalf of or in the
name of eCOST. Except as provided herein, all financial obligations associated
with each party's businesses are the sole responsibility of each respective
party, and nothing in this Agreement is intended to make either party
responsible for the financial obligations of the other.

1.4 Additional Services. From time to time after the Effective Date, the parties
may identify additional services that AF Services will provide to eCOST in
accordance with the terms and conditions of this Agreement ("Additional
Services"). The parties shall create an Exhibit for each Additional Service
setting forth a description of the Additional Service, the charge, if any,
applicable thereto, and any other applicable terms and conditions with respect
to such Additional Service. In order to become a part of this Agreement, such
Exhibit must be executed by a duly authorized representative of each party, at
which time such Additional Service shall be deemed to constitute a "Service" for
purposes hereof and shall be subject to the terms and conditions of this
Agreement. For the avoidance of doubt, the parties may, but shall not be
required to, agree on Additional Services during the term of this Agreement.
Notwithstanding anything to the contrary in the foregoing or elsewhere in this
Agreement, any service actually performed by AF Services upon a written or
verbal request by eCOST in connection with this Agreement shall be deemed to
constitute a "Service" for purposes of Sections 5.1 and 5.2.

1.5      Cooperation; Consents; Alternatives.

(a) Cooperation and Consents. The parties will use good faith efforts to
  cooperate with each other in all matters relating to the provision and receipt
  of the Services, including, without limitation, cooperating in connection with
  obtaining all consents, approvals licenses or sublicenses reasonably necessary
  in order for AF Services to perform the Services. eCOST shall be solely
  responsible for any costs incurred by AF Services in connection with obtaining
  such consents or approvals or procuring such licenses or sublicenses.

(b) Alternatives. In the event that AF Services reasonably believes that it is
  unable to provide any Service because of a failure to obtain any consent,
  approval, license or sublicense, the parties shall in good faith discuss and
  agree to an alternative approach; provided that, in no event shall AF Services
  be required to provide such Service until such time that the parties have
  agreed to an alternative approach or the relevant consent, approval, license
  or sublicense has been obtained. eCOST shall be solely responsible for any
  increased cost in providing a Service resulting from any agreed alternative
  approach.

1.6 Defined Terms. Capitalized terms used and not otherwise defined herein shall
have the meanings given to them in that certain Master Separation and
Distribution Agreement (the "Master Separation and Distribution Agreement"), by
and between PC Mall, Inc., a Delaware corporation ("PC Mall") and eCost, dated

provide eCOST continued usage of the telecommunications systems, including the

same ("Telecommunications Usage").

applicable fees, and provide reasonable detail regarding each of such fees. AF
Services' invoices shall be due and payable by eCOST, in immediately available
funds and as an electronic funds transfer or by such other manner mutually
agreed by the parties, not later than fifteen (15) days after the date of
invoice. Late payments under this Article III shall bear interest at the prime
rate plus two percent (2%) per annum or the maximum amount permitted by
applicable law, whichever is less.

3.4 Additional Systems Costs. Notwithstanding anything to the contrary in this
Agreement, to the extent that AF Services would be required to pay any amounts
to acquire additional hardware, license additional third-party software, pay any
third-party transfer fees or purchase additional third-party services related to
the foregoing, to provide the Services, Telecommunications Usage or Hardware and
Software Usage to eCOST ("Additional Systems Costs"), eCOST shall be responsible
for payment of any such Additional Systems Costs.

3.6 Audit Adjustments. In the event of a tax audit adjustment relating to the
pricing of any Service provided pursuant to this Agreement in which it is
determined by a taxing authority that any of the fees charged hereunder,
individually or in combination, did not constitute an arm's length payment, the
parties will in good faith discuss and agree to make adjustments to the
applicable fees in order to achieve arm's length pricing. Any adjustment made
pursuant to this Section 3.6 shall be reflected in each party's books and
records, and shall create a right to receive payment, in the case of the party
that either overpaid or was under-compensated (as applicable), and an obligation
to make payment, in the case of the party that either underpaid or was
over-compensated (as applicable), in accordance with Section 3.3.

GROSS NEGLIGENCE IN PROVIDING THE SERVICES, AF SERVICES OR ANY AFFILIATE THEREOF
SHALL HAVE NO LIABILITY FOR DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE
SERVICES PROVIDED HEREUNDER, REGARDLESS OF THE FORM OF ACTION GIVING RISE TO

  as of the date of this Agreement, not reasonably foreseeable as of such date
  and not reasonably within the control of AF Services, which prevents in whole
  or in material part the performance by AF Services of its obligations
  hereunder or which renders the performance of such obligations so difficult or

  state or governmental action, riots, disturbance, war, strikes, lockouts,
  slowdowns, prolonged shortage of energy supplies, epidemics, fire, flood,
  hurricane, typhoon, earthquake, lightning and explosion.

  obligations is prevented by such Force Majeure Event. Such notice must include
  a reasonable description of the nature and cause of the Force Majeure Event.
  AF Services will as soon as reasonably practical notify eCOST at such time
  that it is no longer affected by the Force Majeure Event and is able to resume
  providing Services.

(c) Cover. eCOST is entitled, following the occurrence of the Force Majeure
  Event and the receipt of notice from AF Services in accordance with Section
  5.3(b), to contract or provide for the performance of the Services otherwise
  performed by AF Services hereunder. Upon notice of termination of the Force
  Majeure Event, eCOST shall consent to AF Services resuming performance of the
  Services and obligations hereunder.

  software, tools, data, inventions, works of authorship, documentation and
  other innovations of any kind, including, without limitation, any improvements
  or modifications to AF Services' proprietary computer software programs and
  related materials, that AF Services, or personnel working for or through AF
  Services, may make, conceive, develop or reduce to practice, alone or jointly
  with others, in the course of performing the Services or as a result of such
  Services, whether or not eligible for patent, copyright, trademark, trade
  secret or other legal protection. eCOST agrees that all Work Product shall be
  the property of AF Services and hereby assigns all rights it may have in the
  Work Product and in all related patents, patent applications, copyrights, mask
  work rights, trademarks, trade secrets, rights of priority and other
  proprietary rights to AF Services. eCOST acknowledges that AF Services, in its
  sole discretion, shall have the right to license the Work Product or any
  portion thereof, and incorporate the Work Product or any portion thereof into

  hereunder, AF Services hereby grants to eCOST a worldwide, non-exclusive,

  Work Product (in whole or in part) to any third party in any form.

(c) Reservation of Rights. Except as otherwise expressly provided herein,
  nothing in this Agreement shall be deemed to grant, directly or by
  implication, estoppel or otherwise, any right or license with respect to any
  technology or other intellectual property rights, and each party retains all
  right, title and interest in and to their respective technologies and other
  intellectual property rights.

ARTICLE VI

                            REQUESTS FOR INFORMATION
