Cherry Street, Suite 200, Denver, Colorado 80222 (the “Borrower”). The Lender and the Borrower are sometimes individually referred to as a “Party” and collectively as the “Parties”.

W I T N E S S E T H:

WHEREAS, Borrower desires to borrow up to $250,000, in one or several installments (the “Pre Bridge Loan”), to meet the immediate working capital needs of the Borrower prior to the Borrower’s implementation of a proposed $750,000 bridge loan (the “Bridge Loan”); and

WHEREAS, the Lender together with all other third party lenders, each of which shall participate in the Pre Bridge Loan on a pro rata and pari passu basis and who shall each execute its own Pre-Bridge Agreement with the Borrower (collectively the “Additional Lenders”) is willing to lend a portion of the Loan Amount to the Borrower.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements herein contained, the receipt and adequacy of which is hereby acknowledged and accepted, the Parties hereby agree as follows:

1.1 The Pre Bridge Loan. The Lender and the Additional Lenders (hereinafter collectively referred to as the “Participating Lenders”) hereby agree to lend up to $250,000 to the Borrower and the Borrower hereby accepts Loan Amount (defined below) from the Participating Lenders and agrees to repay the same in lawful money of the United States of America. The final amount that shall ultimately be advanced to the Borrower by the Participating Lenders is hereinafter referred to as the “Loan Amount.” The Loan Amount shall be evidenced by a number of identical but separate promissory notes, each bearing interest at the rate of ten (10.0%) percent per annum on an actual day/360 day basis and payable on the Due Date (as that term is defined below), in the specimen form annexed hereto as Exhibit “A” and hereby incorporated herein by reference (collectively the “Notes”). The original Notes shall be duly executed by the Borrower and delivered to the Participating Lenders simultaneously with the execution of individual Pre Bridge Agreements.

1.2 Due Date. The Loan Amount shall be due and payable on the earlier of: (i) the closing of the Bridge Loan; (ii) one year from the date of this Agreement; or (iii) the receipt by each Participating Lender of Commission Income (as that term is defined in Section 1.5 below) equal to its pro rata portion of the Loan Amount (the “Due Date”).

1.3 Payments and Prepayments. Borrower shall not be entitled to re-borrow any prepaid Loan Amounts or other costs or charges. All payments made pursuant to this Pre Bridge Agreement shall be first applied to accrued and unpaid interest, then to any lien or other proper charges under this Pre Bridge Agreement and finally to the aggregated principal balance of the Loan Amount. Absent the foregoing, interest on the Loan Amount shall be due and payable in one lump sum on the Due Date.

1.4 Closings. The closing of the Pre Bridge Loan shall take place simultaneously with the execution of each of the individual Pre Bridge Agreement via facsimile. Simultaneously with the execution of each of the individual Pre Bridge Agreements, the Participating Lenders shall deliver their respective portion of the Loan Amount proceeds to the Borrower via Federal wire transfer or such other manner as shall be mutually agreed upon between the Borrower and the Participating Lender (the “Closings”). At each of the Closings, the Borrower shall deliver an original Pre Bridge Agreement duly executed by the Borrower.

1.5 Collateral Security. As collateral security for the Borrower’s repayment of the Loan Amount to the Participating Lenders (defined below), as evidenced by the filing of the UCC-1 Financing Statement as described in Section 1.6 below, and until the Loan Amount has been repaid, the Borrower hereby covenants and agrees that its President, Clinton J. Wilson and/or such other executive officers or employees designated by him and indicated to the Participating Lenders in writing shall deposit all of the monthly commission income received by the Borrower from its agreements with Qwest Communications and Level 3 Communications (collectively the “Commission Income”) into a separate segregated account to be maintained at Vectra Bank Colorado with respect to which Gary J. Graham, in his capacity as President of First Capital Business Development, LLC, a Colorado limited liability company, located at 16293 East Dorado Place, Centennial, CO 80015 (“FCBD”) in its capacity as collection and disbursement agent for the Additional Lenders (“each Participating Lender”), shall be the sole signatory (the “Account”). The Commission Income shall be deposited into the Account on the first day after the same has been received into the Borrower’s regularly maintained account and cleared collection.

The Borrower shall continue to promptly deposit the Commission Income into the Account until the earlier of: (i) the Participating Lenders having collectively received the full Loan Amount together with all accrued interest from the Commission Income; or (ii) the Participating Lenders having collectively received the full Loan Amount together with all accrued interest from the Bridge Loan.

Simultaneously with the execution of this Pre Bridge Agreement, the Borrower shall execute and deliver to Qwest Communications and Level 3 Communications a letter requesting them to deposit the Commission Income into a designated lock box. The letter shall be delivered via overnight package delivery service or by registered or certified mail with a copy to the Lender.

In its capacity as the lead and first Participating Lender, and without any other legal duty or obligation to do so, FCBD hereby covenants and agrees to faithfully and impartially: (i) collect the Commission Income from the Account; (ii) to disburse the Commission Income pro rata to the Participating Lenders; (iii) to maintain accurate books and records of all transaction for and on behalf of the Participating Lenders; and (iv) as soon as the Participating Lenders are repaid the Loan Amount and all accrued interest from the Commission Income and/or the proceeds of the Bridge Loan, FCBD shall return any un-disbursed Commission Income in its possession back to the Borrower, and shall execute and deliver to the Borrower a UCC-2 Termination Statement evidencing the termination of FCBD’s interest in the Account and in the Commission Income.

In addition to the Commission Income, the Loan Amount shall also be satisfied from the un-pledged assets of the Borrower. Until the Loan Amount together with all accrued interest shall have been repaid in full, any and all free credit balances of the Borrower shall be paid to the Participating Lenders prior to any repayment of trade payables, other indebtedness or investment to equity holders of the Borrower.

1.6 Security Documents and Fees. Simultaneously with the execution and delivery of this Agreement, the Borrower shall execute and deliver to each Participating Lender on behalf of the Participating Lenders a UCC-1 financing statement evidencing the Participating Lender’s First Lien security interest. In addition, the Borrower hereby specifically agrees and consents that a photocopy or other reproduction of this Pre Bridge Agreement shall be deemed to be the legal equivalent of a financing statement and may be filed with any county clerk as evidence of the Participating Lender’s security interest. At the closing of the Bridge Loan, the Borrower shall pay to FCBD a Commission Income processing fee of $25,000.

1.7 Warrants as Additional Consideration. As additional consideration for the Loan Amount, the Borrower hereby covenants and agrees that it shall cause the issuance and delivery to each Participating Lender of a warrant in the specimen form annexed hereto as Exhibit “B” and hereby incorporated herein by reference with a ten (10) year term (the “Warrants”) entitling the Participating Lenders to purchase an aggregate of one share of the Borrower’s Common Stock, $.001 par value per share (the “Shares”), at an exercise price of $0.75 per Share or such greater or lesser amount paid by the investors in the Bridge Loan for each one Dollar loaned to the Borrower and aggregating the Loan Amount (the “Warrant Shares”). The Warrant Shares shall be registered under the Securities Act of 1933, as amended (the “Securities Act”), in accordance with the following:

A. If at any time during the ten year term of the Warrants, the Borrower proposes to file a Registration Statement under the Securities Act (a “Registration Statement”); it will at such time give written notice to each Participating Lender of its intention to do so. Upon written request of any Participating Lender, given within 15 days after the giving of any such notice by the Borrower, the Borrower will advise such Participating Lender that it shall include its Warrant Shares in the Registration Statement. If, however, the offering to which the Registration Statement relates is to be distributed by or through an underwriter approved by the Borrower, each Participating Lender hereof may at its option agree to sell the Warrant Shares through such underwriter on the same terms and conditions as the underwriter agrees to sell the other securities proposed to be registered. In addition, if such underwriter determines that the inclusion of all the Warrant Shares sought to be sold would have an adverse effect on the offering, each Participating Lender shall be entitled to participate in the underwriting and register

its Warrant Shares on a pro rata basis or as such other quantity of the Warrant Shares as the underwriter may determine. If any Participating Lender hereof elects not to sell its Warrant Shares through such underwriter, the Participating Lender may use the Registration Statement to register its Warrant Shares under the Securities Act within 60 days after the Registration Statement becomes effective;

B. The Borrower covenants and agrees that it shall prepare and promptly file with the Securities and Exchange Commission (the “Commission”) all amendments, post-effective amendments and supplements to the Registration Statement as may be necessary under the Securities Act and the regulations of the Commission to permit the sale of the Warrant Shares to the public; and

G. Investment Representations. The Holder has been advised, and by the acceptance of this Note, agrees and acknowledges that until and unless the Conversion Shares have been registered under the Securities Act of 1933, as amended (the “Securities Act”), none of the Conversion Shares issuable upon conversion of this Note shall have been registered under the Securities Act or under any state securities law; and that the Borrower is relying upon an exemption from registration based upon the Holder’s investment representations. In this regard, the Holder hereby represents and warrants to the Borrower that: (i) in the event the Holder avails itself of the conversion feature of this Note, the Holder will acquire the Conversion Shares for investment purposes and without a view to the transfer or resale thereof; (ii) in the event the Holder avails itself of the conversion feature of this Note, the Holder will hold the Conversion until the earlier of the effective date of the Registration Statement defined in Section H below or such later time after one as may be required under the Securities Act; (iii) any sale of the Conversion Shares will be accomplished only in accordance with the Securities Act and the rules

1). If at any time prior to the repayment of the full Loan Amount, the Borrower proposes to file a Registration Statement under the Securities Act (a “Registration Statement”); it will at such time give written notice to each Holder of its intention to do so. Upon written request of any Holder, given within 15 days after the giving of any such notice by the Borrower, the Borrower will advise such Holder that it shall include its Conversion Shares in the Registration Statement. If, however, the offering to which the Registration Statement relates is to be distributed by or through an underwriter approved by the Borrower, each Holder hereof may at its option agree to sell the Conversion Shares through such underwriter on the same terms and conditions as the underwriter agrees to sell the other securities proposed to be registered. In addition, if such underwriter determines that the inclusion of all the Conversion Shares sought to be sold would have an adverse effect on the offering, each Holder shall be entitled to participate in the underwriting and register its Conversion Shares on a pro rata basis or as such other quantity of the Conversion Shares as the underwriter may determine. If any Holder hereof elect not to sell its Conversion Shares through such underwriter, the Holder r may use the Registration Statement to register its Conversion Shares under the Securities Act within 60 days after the Registration Statement becomes effective;

B. The Borrower covenants and agrees that it shall prepare and promptly file with the Securities and Exchange Commission (the “Commission”) all amendments, post-effective amendments and supplements to the Registration Statement as may be necessary under the Securities Act and the regulations of the Commission to permit the sale of the Conversion Shares to the public; and

C. The rights of the Holders hereof pursuant to this Section 2 may be exercised only by each Holder or any affiliate thereof.

This Note is made pursuant to the Agreement. Any default of any obligation by the Borrower under this Note shall constitute an Event of Default of the obligations of the Company under the Agreement, and any Event of Default under the Agreement shall constitute an Event of Default under this Note. The Borrower acknowledges that this Note is enforceable, valid and binding upon the Borrower. If for any reason, any court authority or governmental entity declares this Note invalid, unlawful or against public policy, then, the parties hereto acknowledge that neither the obligation of the Borrower to repay the Note, nor any of the covenants, obligations or representations of the parties contained within the Agreement shall be affected by such declaration.

Upon the occurrence of an Event of Default, as that term is defined in Section 3 of the Agreement, then and in such event, the Borrower will be deemed to have defaulted under this Note and the Holder(s) may, on written notice, accelerate all payments due under this Note or have the rights and remedies set forth in Section 3 of the Agreement.
