Provided that no Event of Default is in existence and that the requested Advance would not cause an Event of Default to occur, Lender shall make the Advance to Borrower within five (5) days of receipt of Borrower’s notice. Lender shall not be obligated to make an Advance to the extent that such Advance when aggregated with all Advances would exceed Six Million Dollars ($6,000,000) in the aggregate.

F. Subordination. Except as provided in the immediately following sentence, for as long as no event of default on the Senior Indebtedness (as defined below) has occurred and is continuing, Borrower shall make no payment of principal on account of the Senior Indebtedness until prior payment in full of the Secured Obligations.

3. Subrogation. After, and during the continuance of, an event of default on the Senior Indebtedness, subject to the payment in full of all Senior Indebtedness, Lender’s rights under this Note shall be subrogated to the rights of the holder(s) of such Senior Indebtedness (to the extent of the payments or distributions made to the holder(s) of such Senior Indebtedness pursuant to the provisions of this Section) to receive payments and distributions of assets of Borrower applicable to the Senior Indebtedness. No such payments or distributions applicable to the Senior Indebtedness shall, as between Borrower and its creditors, other than the holders of Senior Indebtedness and Lender, be deemed to be a payment by Borrower to or on account of this Note; and for purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness to which Lender would be entitled except for the provisions of this Section shall, as between Borrower and its creditors, other than the holders of Senior Indebtedness and Lender, be deemed to be a payment by Borrower to or on account of the Senior Indebtedness.

(d) the loss, theft, damage or destruction of, or sale (other than in the ordinary course of business), lease or furnishing under a contract of service of, any material portion of the Collateral;

(e) the creation (whether voluntary or involuntary) of, or any attempt to create, any Lien upon any of the Collateral, other than the Permitted Liens, or any levy, seizure or attachment of any material portion thereof;

(f) the occurrence and continuance of any default under any lease or agreement for borrowed money that gives the lessor or the creditor of such indebtedness, as applicable, the right to accelerate the lease payments or the indebtedness, as applicable, or the right to exercise any rights or remedies with respect to any of the Collateral; or

(g) the entry of any judgment or order against Borrower which remains unsatisfied or undischarged and in effect for thirty (30) days after such entry without a stay of enforcement or execution.

2. Rights and Remedies on Event of Default.

(a) During the continuance of an Event of Default, Lender shall have the right, itself or through any of its agents, with or without notice to Borrower (as provided below), as to any or all of the Collateral, by any available judicial procedure, or without judicial process (provided, however, that it is in compliance with the UCC), to exercise any and all rights afforded to a secured party under the UCC or other applicable law. Without limiting the generality of the foregoing, Lender shall have the right to sell or otherwise dispose of all or any part of the Collateral, either at public or private sale, in lots or in bulk, for cash or for credit, with or without warranties or representations, and upon such terms and conditions, all as Lender, in its reasonable discretion, may deem advisable, and it shall have the right to purchase at any such sale. Borrower agrees that a notice sent at least fifteen (15) days before the time of any intended public sale or of the time after which any private sale or other disposition of the Collateral is to be made shall be reasonable notice of such sale or other disposition. The proceeds of any such sale, or other Collateral disposition shall be applied, first to the expenses of retaking, holding, storing, processing and preparing for sale, selling, and the like, and to Lender’s reasonable attorneys’ fees and legal expenses, and then to the Secured Obligations and to the payment of any other amounts required by applicable law, after which Lender shall account to Borrower for any surplus proceeds. If, upon the sale or other disposition of the Collateral, the proceeds thereof are insufficient to pay all amounts to which Lender is legally entitled, Borrower shall be liable for the deficiency, together with interest thereon, and the reasonable fees of any attorneys Lender’s employs to collect such deficiency; provided, however, that the foregoing shall not be deemed to require Lender to resort to or initiate proceedings against the Collateral prior to the collection of any such deficiency from Borrower. To the extent permitted by applicable law, Borrower waives all claims, damages and demands against Lender arising out of the retention or sale or lease of the Collateral or other exercise of Lender’s rights and remedies with respect thereto.

(b) To the extent permitted by law, Borrower covenants that it will not at any time insist upon or plead, or in any manner whatever claim or take any benefit or advantage of, any stay or extension law now or at any time hereafter in force, nor claim, take or insist upon any benefit or advantage of or from any law now or hereafter in force providing for the valuation or appraisal of the Collateral or any part thereof, prior to any sale or sales thereof to be made pursuant to any provision herein contained, or the decree, judgment or order of any court of competent jurisdiction; or, after such sale or sales, claim or exercise any right under any statute now or hereafter made or enacted by any state or otherwise to redeem the property so sold or any part thereof, and, to the full extent legally permitted, hereby expressly waives all benefit and advantage of any such law or laws, and covenants that it will not invoke or utilize any such law or laws or otherwise hinder, delay or impede the execution of any power herein granted and delegated to Lender, but will suffer and permit the execution of every such power as though no such power, law or laws had been made or enacted.

(c) Any sale, whether under any power of sale hereby given or by virtue of judicial proceedings, shall operate to divest all Borrower’s right, title, interest, claim and demand whatsoever, either at law or in equity, in and to the Collateral sold, and shall be a perpetual bar, both at law and in equity, against Borrower, its successors and assigns, and against all persons and entities claiming the Collateral sold or any part thereof under, by or through Borrower, its successors or assigns.

(d) Borrower appoints Lender, and any officer, employee or agent of Lender, with full power of substitution, as Borrower’s true and lawful attorney-in-fact, effective as of the date hereof, with power, in its own name or in the name of Borrower, during the continuance of an Event of Default, to endorse any notes, checks, drafts, money orders, or other instruments of payment in respect of the Collateral that may come into Lender’s possession, to sign and endorse any drafts against debtors, assignments, verifications and notices in connection with accounts, and other documents relating to Collateral; to pay or discharge taxes or Liens at any time levied or placed on or threatened against the Collateral; to demand, collect, issue receipt for, compromise, settle and sue for monies due in respect of the Collateral; to notify persons and entities obligated with respect to the Collateral to make payments directly to Lender; and, generally, to do, at Lender’s option and at Borrower’s expense, at any time, or from time to time, all acts and things which Lender deems necessary to protect, preserve and realize upon the Collateral and Lender’s security interest therein to effect the intent of the Loan Documents, all as fully and effectually as Borrower might or could do; and Borrower hereby ratifies all that said attorney shall lawfully do or cause to be done by virtue hereof. This power of attorney shall be irrevocable as long as any of the Secured Obligations are outstanding.

(e) All of Lender’s rights and remedies with respect to the Collateral, whether established hereby or by any other agreements, instruments or documents or by law shall be cumulative and may be exercised singly or concurrently.

K. Conversion Right.

1. Conversion Right. Lender shall have the right (the “Conversion Right”), in its sole discretion, at any time and from time to time to elect to convert all or any part of the Secured Obligations into that number of shares of Common Stock of Borrower as is obtained by dividing (a) the total amount of Secured Obligations by (b) the conversion price (the “Conversion Price”), which is equal to the lesser of (i) eighty percent (80%) of the five-day moving average price per share of the Common Stock (on the date of the Lender’s election to exercise its Conversion Right or (ii) $1.36 (which is equal 80% of the price per share of the Common Stock on July 27, 2005). If the Borrower at any time subdivides (by any stock split, stock dividend, recapitalization or otherwise, one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and if the Borrower at any time combines (by reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination shall be proportionately increased.

2. Exercise of Conversion Right. To convert any of the Secured Obligations into shares of Common Stock, Lender shall deliver to Borrower a written notice of election to exercise the Conversion Right (the “Conversion Notice”). Borrower shall, as soon as practicable thereafter, issue and deliver to Lender a certificate or certificates, registered in Lender’s name, for the number of shares of Common Stock to which Lender shall be entitled by virtue of such exercise. The conversion of the Secured Obligations shall be deemed to have been made on the date that Borrower receives the Conversion Notice (the “Conversion Date”) and Lender shall be treated for all purposes as the record holder of the Conversion Shares as of such date.

3. Fractional Shares. Borrower shall not issue fractional shares of Common Stock or scrip representing fractional shares of Common Stock upon exercise of the Conversion Right. As to any fractional share of Common Stock which Lender would otherwise be entitled to purchase from Borrower upon such exercise, Borrower shall purchase from Lender such fractional share at a price equal to an amount calculated by multiplying such fractional share (calculated to the nearest 1/100th of a share) by the price per share of Common Stock on the Conversion Date. Payment of such amount shall be made in cash or by check payable to the order of Lender at the time of delivery of any certificate or certificates arising upon such exercise.

L. Registration Rights. Concurrent with the execution and delivery of this Note, Borrower shall take all actions necessary to cause Lender, upon the exercise of the Conversion Right provided for herein, to have similar registration and similar liquidity rights as the rights granted to the participants in HyperFeed’s Private Placement dated May 15, 2003, and during the term of this Note no stockholder of Borrower shall have more favorable registration or other liquidity rights than the rights granted to Lender pursuant to this Section.
