Exhibit 10c-1

                            REVOLVING LOAN AGREEMENT


         This Revolving Loan Agreement (the "Agreement") is effective as January
20, 2005 by and between Robert Shively and Geoff Shively (the "Lenders"), and
PivX Solutions, Inc. (the "Borrower").

1.       Lenders hereby agree to lend the sum of five hundred thousand dollars
         ($500,000) to Borrower, and Borrower agrees to borrow the said sum from
         Lenders upon the terms and conditions set forth herein.

2.       Lender agrees that from time to time during the term of this Agreement
         it shall lend at its discretion to Borrower sums which, in the
         aggregate principal amount outstanding at any one time, shall not
         exceed $500,000 (the "Credit").

         (a)      The Credit shall be a revolving credit and Borrower may
                  request advances, repay and re-borrow amounts during the
                  continuation of the Credit, as Lenders may in their discretion
                  deem advisable, subject to the applicable provisions of this
                  Agreement. Each such revolving credit loan made hereunder (an
                  "Advance") shall have a scheduled maturity date ("Scheduled
                  Maturity Date") of July 20, 2005, unless previously paid. All
                  such Advances made hereunder shall be included on the schedule
                  contained in the "Revolving Promissory Note" referred to in
                  paragraph 2(c) below which schedule by this reference is made
                  a part hereof.

         (b)      This agreement shall terminate on July 20, 2005 and no new
                  advances hereunder shall be made on or after that date.
                  Notwithstanding the above, if any Advances made hereunder are
                  still outstanding as of this Agreement shall continue in full
                  force and effect with respect to such Advances until such
                  Advances are repaid.

         (c)      The obligation of Borrower to repay the aggregate unpaid
                  principal amount of the Advances shall be evidenced by a
                  single promissory note of Borrower bearing on its face an
                  appropriate legend stating that such note is subject to the
                  provisions of this Agreement, which shall be adequately
                  referred to and incorporated herein (the "Revolving Promissory
                  Note"). The Revolving Promissory Note shall be payable to the
                  order of the Lender in a face amount equal to the Credit,
                  bearing no interest. The Revolving Promissory Note shall be
                  dated, and shall be delivered to Lenders, on the date of the
                  execution and delivery of this Agreement by Borrower. Lenders
                  shall, and are hereby authorized by Borrower to, endorse on
                  the schedule contained on the Revolving Promissory Note, or on
                  a continuation of such schedule attached thereto and made a
                  part thereof and hereof, appropriate notations regarding the
                  Advances evidenced by the Revolving Promissory Note as
                  specifically provided therein; provided, however, that the
                  failure to make, or error in making, any such notation shall
                  not limit or otherwise affect the obligations of Borrower
                  hereunder or under the Revolving Promissory Note.

                                       1

         (d)      The unpaid principal amount of an Advance shall bear no
                  interest prior to its Scheduled Maturity Date. After the
                  Scheduled Maturity Date, the unpaid principal amount of the
                  Advance shall bear interest until paid at ten percent (10%).
                  All interest shall be computed on the basis of a year
                  consisting of 365 days and paid for the actual number of days
                  elapsed.

         (e)      Notwithstanding any term hereof to the contrary, Lender
                  reserves the right to make any Advance hereunder in its sole
                  and absolute discretion. It is expressly understood and agreed
                  by Borrower and each of its successors and permitted assigns
                  that nothing herein creates any liability on Lender, its
                  successors and permitted assigns that nothing herein creates
                  any liability on Lender, its successors or permitted assigns
                  to make any Advance.

         (f)      Whenever Borrower desires Lenders to make an Advance, it shall
                  give written notice via email to Lenders of such Advance,
                  setting forth the amount of the Advance and the date on which
                  such Advance is to be made.

3.       The Lenders hereby agree that any right to receive any payment with
         respect to this Agreement prior to the Scheduled Maturity Date shall be
         determined and made at the discretion of the CEO, CFO and General
         Counsel of Borrower.

4.       The proceeds of this Agreement shall be used and dealt with by the
         Borrower as part of its capital and shall be subject to the risks of
         its business.

5.       The Borrower shall have the right to deposit any cash proceeds of this
         loan agreement in an account or accounts in its own name in any bank or
         trust company.

6.       The payment obligation of the Borrower with respect to this Agreement,
         together with accrued interest and compensation, shall mature in the
         event of any receivership, insolvency, liquidation pursuant to the
         Securities Investor Protection Act of 1970 or otherwise, bankruptcy,
         assignment for the benefit of creditors, reorganization whether or not
         pursuant to the bankruptcy laws, or any other marshalling of the assets
         and liabilities of the Borrower, but the right of the Lenders to
         receive payment, together with accrued interest or compensation, shall
         remain subordinate as required by the provisions of this Agreement.

7.       Neither this Agreement nor any note or other instrument made hereunder
         is entered into in reliance upon the standing of the Borrower as a
         member organization of any commodity exchange or securities exchange or
         upon any such exchange's surveillance of the Borrower or its capital
         position. The Lenders are not relying upon any such exchange to provide
         any information concerning or relating to the Borrower. No such


                                       2

         exchange has a responsibility to disclose to the Lenders any
         information concerning or relating to the Borrower which it may have
         now or at any future time. Neither any such exchange nor any officer or
         employee of any such exchange shall be liable to the Lenders with
         respect to this Agreement, the Indebtedness, the repayment thereof, any
         interest or compensation thereon or any damages resulting from the
         breach of this Agreement.

8.       This Agreement shall be binding upon the Lenders and the Borrower and
         their respective heirs, executors, administrators, successors and
         assigns.

9.       Any note or other written instrument evidencing the Indebtedness shall
         bear on its face an appropriate legend stating that such note or
         instrument is issued subject to the provisions of this Agreement, which
         shall be adequately referred to and incorporated by reference herein.

10.      This Agreement shall not be subject to cancellation by either party; no
         payment shall be made with respect thereto and this Agreement shall not
         be terminated, rescinded or modified by mutual consent or otherwise if
         the effect thereof would be inconsistent with the Capital Requirements.

11.      This Agreement is governed by the laws of the State of California.

12.      Any notice required or provided for herein shall be deemed to have been
         given or received when it has been delivered in person or has been
         deposited, postage prepaid, by United States certified or registered
         mail, addressed to the person for whom intended:

         (a) If for Borrower:
         ____________________________________________
         ____________________________________________

         (b) If for Lender:
