THIS AGREEMENT AND PLAN OF MERGER, dated June , 2006 (the “Agreement”), by and among HyperFeed Technologies, Inc., a Delaware corporation (“HyperFeed”), HyperFeed Acquisition Holdings, Inc., a Delaware corporation and wholly-owned direct subsidiary of HyperFeed (“Merger Sub”), and Exegy Incorporated, a Delaware corporation (“Exegy”).

WHEREAS, the respective Boards of Directors of Exegy, HyperFeed and Merger Sub have determined that the merger of Merger Sub with and into Exegy (the “Merger”) in accordance with the Delaware General Corporation Law (the “DGCL”), in the manner provided by, and subject to the terms and conditions of, this Agreement, is advisable and in the best interest of their respective companies and their stockholders; and

WHEREAS, it is the intent of the parties that, following the Merger, the current stockholders, together with option holders, of HyperFeed will collectively own on a fully-diluted basis fifty percent (50%) of the outstanding common stock of HyperFeed and the current stockholders, together with option holders, of Exegy will collectively own on a fully-diluted basis fifty percent (50%) of the outstanding common stock of HyperFeed; and

WHEREAS, accordingly, the respective Boards of Directors of HyperFeed, Exegy and Merger Sub have approved the Merger, in each case upon the terms and subject to the conditions set forth herein; and

WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a tax-free reorganization within the meaning of Section 368(a) of the Code, and the parties hereto intend, by executing this Agreement, to adopt a plan of reorganization within the meaning of Section 368(a) of the Code.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, the parties hereto, intending to be legally bound, hereby agree as follows:

For purposes of this Agreement, the capitalized terms used in this Agreement shall have the meanings specified or referred to in Appendix I hereto which is incorporated herein by reference.

Section 2.1. The Merger. Upon the terms of, and subject to the conditions set forth in, this Agreement and in accordance with the DGCL, at the Effective Time, Merger Sub shall be merged with and into Exegy. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and all outstanding shares of Merger Sub’s capital stock shall be converted into shares of Exegy Common Stock and Exegy shall continue as the surviving corporation (sometimes referred to herein as the “Surviving Corporation”).

Section 2.2. Effective Time; Closing. As soon as practicable after the satisfaction or, if possible, waiver of the conditions set forth in Article VII, but in no event later than the second Business Day following the satisfaction or, if permissible, waiver of the conditions set forth in Article VII (such date being the “Closing Date”), the parties hereto shall cause the Merger to be consummated by filing a Certificate of Merger, substantially in the form of Exhibit A (the “Certificate of Merger”), with the Secretary of State of the State of Delaware in such form as required by and executed in accordance with the relevant provisions of the DGCL. Immediately prior to the filing of the Certificate of Merger, the closing (the “Closing”) will be held at the offices of Stinson Morrison Hecker LLP, 100 South Fourth Street, St. Louis, Missouri 63102 or at such other place as the parties may agree to confirm the satisfaction or waiver of the conditions set forth in Article VII.

Section 2.3. Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of Exegy and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities, obligations and duties of each of Exegy and Merger Sub shall become the debts, liabilities, obligations and duties of the Surviving Corporation.

Section 2.4. Certificate of Incorporation; Bylaws. At the Effective Time, the Certificate of Incorporation of the Surviving Corporation shall be the Certificate of Incorporation of Exegy as in effect immediately prior to the Effective Time, and shall remain so until thereafter amended as provided by Law and such Certificate of Incorporation. At the Effective Time, the Bylaws of the Surviving Corporation shall be the Bylaws of Exegy as in effect immediately prior to the Effective Time, and shall remain so until thereafter amended as provided by Law, the Certificate of Incorporation of the Surviving Corporation and such Bylaws.

(a) The directors of the Surviving Corporation at the Effective Time shall be the directors of Exegy immediately prior to the Effective Time, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation until their respective successors are duly elected or appointed and qualified.

(b) The officers of the Surviving Corporation at the Effective Time shall be the officers of Exegy immediately prior to the Effective Time, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation until their respective successors are duly elected or appointed and qualified.

Section 2.6. Name Change. At the Effective Time, HyperFeed and the Surviving Corporation shall take, or cause to be taken, such actions as necessary to effect the change of HyperFeed’s corporate name to “Exegy Incorporated.”

(a) Preferred Stock. By virtue of the Merger and without any action on the part of Exegy, HyperFeed, Merger Sub or any of their respective stockholders, at the Effective Time, each share of Exegy Preferred Stock outstanding as of the date of this Agreement shall be converted, in accordance with its terms, into shares of Exegy Common Stock.

(b) Common Stock. By virtue of the Merger and without any action on the part of Exegy, HyperFeed, Merger Sub or any of their respective stockholders, at the Effective Time, each share of Exegy Common Stock then issued and outstanding, including the Exegy Common Stock issued upon conversion of the Exegy Preferred Stock in accordance with Section 3.1(a), other than those shares of Exegy Common Stock issued to HyperFeed upon the conversion of Merger Sub’s capital stock pursuant to Section 2.1 and those shares of Exegy Common Stock to be canceled pursuant to Section 3.6 (the “Exchange Shares”), shall forthwith cease to exist and shall be converted into the number of validly issued, fully paid and nonassessable shares of HyperFeed Common Stock determined as set forth in Section 3.2.

(a) The aggregate number of shares of HyperFeed Common Stock to be issued in exchange for the Exchange Shares shall be equal to the product of (a) the total number of shares of Exegy Common Stock actually outstanding as of the Effective Time, multiplied by (b) the quotient of (x) the total number of shares of HyperFeed Common Stock outstanding immediately prior to the Effective Time (determined on a fully-diluted basis), divided by (y) the total number of shares of Exegy Common Stock outstanding as of the Effective Time (determined on a fully diluted basis) (such product, the “Exchange Consideration”).

(b) Notwithstanding the foregoing, it is the intent of the parties that: (i) the HyperFeed Common Stock outstanding immediately before the Effective Time, the HyperFeed Common Stock subject to stock option plans, agreements or other equity based plans immediately before the Effective Time, and the HyperFeed Common Stock reserved for the options described in Section 3.2(c) in the aggregate will equal 50% of the outstanding HyperFeed Common Stock on a fully-diluted basis immediately after the Effective Time, and (ii) the Exchange Shares (as defined in Section 3.1(b)) and the shares of HyperFeed Common Stock subject to Exchange Options (as defined in Section 3.3) in the aggregate will equal 50% of the outstanding HyperFeed Common Stock on a fully-diluted basis immediately after the Effective Time.

(c) The parties acknowledge that on a fully-diluted basis the percentage of outstanding Exegy Common Stock subject to or reserved for compensatory stock options exceeds the percentage of outstanding HyperFeed Common Stock subject to or reserved for compensatory stock options, and agree that those percentages should be equal. Accordingly, before the Effective Time, HyperFeed will reserve a sufficient number of shares of HyperFeed Common Stock for issuance pursuant to stock option plans, agreements or other equity based plans to cause the above described percentages to be equal immediately upon the Effective Time.

(a) By virtue of the Merger and without any action on the part of Exegy, HyperFeed, Merger Sub or any of their respective stockholders, at the Effective Time, each option to purchase shares of Exegy Common Stock outstanding immediately prior to the Effective Time (each, an “Exegy Option”), shall, as of the Effective Time, cease to exist and be converted into an option to purchase shares of HyperFeed Common Stock on the same terms and at the same price (each, an “Exchange Option”). Each Exchange Option shall represent the right of its holder to purchase a number of shares of HyperFeed Common Stock equal to the product of (x) the number of shares of Exegy Common Stock covered by the Exegy Option converted pursuant to this Section 3.3, multiplied by (y) the quotient of (a) the total number of shares of HyperFeed Common Stock outstanding immediately prior to the Effective Time (determined on a fully-diluted basis), divided by (b) the total number of shares of Exegy Common Stock outstanding as of the Effective Time (determined on a fully-diluted basis).

(b) The number of shares of HyperFeed Common Stock issuable upon exercise, the exercise price per share, the vesting provisions and the expiration date of the Exchange Options which will be issued in exchange for the Exegy Options shall comply in all respects with the requirements of Section 1.424-1 of the Treasury Regulations governing the substitution and assumption of options. The parties intend that the terms of the replacement of the Exegy Options with Exchange Options comply in all respects with Section 409A of the Code and that the foregoing provisions be construed in a manner consistent with such intent.

Section 3.4. Issuance of Exchange Consideration and Grant of Exchange Options. Immediately following the Effective Time, HyperFeed shall:

(a) issue to each holder of Exchange Shares (determined as of immediately prior to the Effective Time) a certificate(s) representing a proportion of the Exchange Consideration equal to the proportion that the number of Exchange Shares held by such holder immediately prior to the Effective Time represents of the aggregate number of Exchange Shares held by all such holders immediately prior to the Effective Time; and

(b) issue to each holder of an Exegy Option (determined as of immediately prior to the Effective Time) an Exchange Option pursuant to Section 3.3.

(a) Immediately following the Effective Time, Exegy shall cause each of the Exegy stockholders, to the extent such are then in their possession or under their control, to surrender, or cause to be surrendered, to HyperFeed all share certificates representing Exchange Shares and all Exegy Options in accordance with this Section 3.5.

(b) As soon as practicable after the Effective Time, HyperFeed will mail to each holder of record of one or more certificates representing Exchange Shares (the “Exchange Certificates”) a letter of transmittal in customary form as reasonably agreed to by the parties (which will specify, among other things, that delivery will be effected, and risk of loss and title to the Exchange Certificates will pass, only upon delivery of the Exchange Certificates to HyperFeed) and instructions for use in effecting the surrender of the Exchange Certificates in exchange for certificates representing the shares of HyperFeed Common Stock and any cash in lieu of fractional shares into which the shares of Exegy Common Stock represented by such Exchange Certificate or Exchange Certificates have been converted pursuant to this Agreement. Upon proper surrender of an Exchange Certificate or Exchange Certificates for exchange and cancellation to HyperFeed, together with such properly completed letter of transmittal, duly executed, and such other documents as may reasonably be required by HyperFeed, the holder of such Exchange Certificate or Exchange Certificates will be entitled to receive in exchange therefore, as applicable, (i) certificate(s) representing the number of whole shares of HyperFeed Common Stock to which such holder of Exegy Common Stock has become entitled pursuant to the provisions of Article III and (ii) any cash in lieu of fractional share of HyperFeed Common Stock that such holder has the right to receive in respect of the Exchange Certificate or Exchange Certificates surrendered pursuant to the provisions of this Article III and any dividends or distributions then payable pursuant to Section 3.5(c), and the Exchange Certificate or Exchange Certificates so surrendered will forthwith be canceled. No interest will be paid or accrued on any cash in lieu of fractional shares or any unpaid dividends and distributions payable to holders of Exchange Certificates.

(c) No dividends or other distributions declared with respect to HyperFeed Common Stock will be paid to the holder of any unsurrendered Exchange Certificate until the holder thereof surrenders such Exchange Certificate in accordance with this Article III. After the surrender of an Exchange Certificate in accordance with this Article III, the record holder thereof will be entitled to receive (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore paid, without any interest thereon, with respect to the whole shares of HyperFeed Common Stock represented by such Exchange Certificate and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender, with respect to shares of HyperFeed Common Stock represented by such Exchange Certificate.

(d) If any certificate representing shares of HyperFeed Common Stock is to be issued in a name other than that in which the Exchange Certificate or Exchange Certificates surrendered in exchange therefore is or are registered, it will be a condition to the issuance thereof that the Exchange Certificate or Exchange Certificates so surrendered will be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the Person requesting such exchange will pay to HyperFeed in advance any transfer or other Taxes required by reason of the issuance of a certificate representing shares of HyperFeed Common Stock in any name other than that of the registered holder of the Exchange Certificate or Exchange Certificates surrendered, or required for any other reason, or will establish to the satisfaction of HyperFeed that such Tax has been paid or is not payable.

(e) After the Effective Time, there will be no transfers on the stock transfer books of Exegy of the shares of Exegy capital stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of Exegy capital stock that occurred prior to the Effective Time. If, after the Effective Time, Exchange Certificates are presented for transfer to HyperFeed, they will be canceled and exchanged for Exchange Consideration as provided in this Article III.

(f) Any portion of the Exchange Consideration that remains unclaimed by the former stockholders of Exegy as of the first anniversary of the Effective Time will be delivered to HyperFeed. Any former stockholders of Exegy who have not theretofore complied with this Article III will thereafter look only to HyperFeed for payment of the Exchange Consideration and any unpaid dividends and distributions on the HyperFeed Common Stock deliverable in respect of each Exchange Share that such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Exegy, HyperFeed, the Surviving Company, or any other Person will be liable to any former holder of Exchange Shares for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar Laws.

(g) In the event any Exchange Certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Exchange Certificate to be lost, stolen or destroyed and, if required by HyperFeed, the posting by such Person of a bond in such amount as HyperFeed may determine is necessary as indemnity against any claim that may be made against it with respect to such Exchange Certificate, HyperFeed will issue in exchange for such lost, stolen or destroyed Exchange Certificate the Exchange Consideration, any cash in lieu of fractional share of HyperFeed Common Stock, and any unpaid dividends and distributions deliverable in respect thereof pursuant to this Agreement.

Section 3.6. Cancellation of Treasury Shares. Each share of Exegy Common Stock held in the Exegy treasury immediately prior to the Effective Time, by virtue of the Merger and without any action on the part of Exegy, shall cease to be outstanding, shall be canceled and retired without payment of any consideration therefore and shall cease to exist.

Section 3.7. No Fractional Shares. No fraction of a share of HyperFeed Common Stock shall be issued, but in lieu thereof, each holder of Exchange Shares who would otherwise be entitled to a fraction of a share of HyperFeed Common Stock pursuant to Section 3.1 shall be paid an amount in cash by HyperFeed (without interest) equal to the value of such fraction of a share based upon the HyperFeed Share Value.

Section 3.8. Split, Subdivision or Combination of Shares. If either HyperFeed or Exegy at any time shall split, subdivide, reclassify or combine the HyperFeed Common Stock or the Exegy Common Stock, as the case may be, into a different number of securities of the same class, the calculations of conversion, the Exchange Consideration and the HyperFeed Share Value provided for in Sections 3.1, 3.2, 3.3, and 3.7 of this Agreement shall be proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination or reverse stock split.

(a) Notwithstanding any provision of this Agreement to the contrary and to the extent available under the DGCL, any shares of Exegy capital stock outstanding immediately prior to the Effective Time that are held by a stockholder who has neither voted in favor of the Merger nor consented thereto in writing and who has demanded properly in writing appraisal for such shares in accordance with Section 262 of the DGCL (collectively, the “Exegy Dissenting Shares”) will not be converted into, or represent the right to receive, the Exchange Consideration. Such stockholders will be entitled to receive payment of the appraised value of Exegy Dissenting Shares held by them in accordance with the provisions of such Section 262, except that all Exegy Dissenting Shares held by stockholders who have failed to perfect or who effectively have withdrawn or lost their rights to appraisal of such Exegy Dissenting Shares under such Section 262 will thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Exchange Consideration and any unpaid dividends and distributions, without any interest thereon, in the manner provided in Sections 3.1 and 3.7. Notwithstanding anything to the contrary contained in this Section 3.9, if the Merger is rescinded or abandoned, then the right of any stockholder to be paid the fair value of such stockholder’s Exegy Dissenting Shares pursuant to Section 262 of the DGCL will cease.

(b) Exegy will give HyperFeed prompt notice and copies of any demands for appraisal received by Exegy, withdrawals of such demands, and any other instruments served or sent pursuant to the DGCL and received by Exegy. Exegy will not, except with the prior written consent of HyperFeed (which will not be unreasonably withheld), make any payment with respect to any demands for appraisal or offer to settle or settle any such demands or agree to do any of the foregoing.

Section 3.10. Withholding. Each of the Surviving Corporation and HyperFeed shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Article III any amounts as are required to be deduced or withheld pursuant to applicable law. Any amounts so deducted or withheld shall be treated as having been paid to the person in respect of which such deduction or withholding was made.

Section 3.11. Tax Consequences. It is intended by the parties hereto that the Merger shall constitute a reorganization within the meaning of Section 368(a) of the Code.

Except as disclosed in (a) any publicly available report, form, schedule, definitive registration statement or definitive proxy statement filed since May 9, 2006 by HyperFeed with the SEC pursuant to the Securities Act, as amended, or the Exchange Act, as amended (collectively, “HyperFeed SEC Reports”) or (b) the HyperFeed Disclosure Schedule delivered by HyperFeed to Exegy separately prior to, or contemporaneously with, the date hereof (each section or subsection of which qualifies the correspondingly numbered representation or warranty to the extent specified therein); provided, however, that any information set forth in one section of the HyperFeed Disclosure Schedule will be deemed to apply to each other section or subsection of this Agreement to which its relevance is reasonably apparent; provided, further, that notwithstanding anything in this Agreement to the contrary, the inclusion of an item in such schedule as an exception to a representation or warranty will not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item has or would reasonably be expected to have a Material Adverse Effect on HyperFeed, HyperFeed represents and warrants to Exegy that:

Each such plan has received or is reasonably permitted to rely on a determination letter from the Internal Revenue Service to the effect that such plan is qualified and its related trust is exempt from federal income taxes. HyperFeed has furnished, or will make available upon request, to Exegy copies of the most recent Internal Revenue Service determination letters with respect to each such HyperFeed Employee Plan. Each HyperFeed Employee Plan has been maintained and administered in substantial compliance with its terms (except that in any case in which any HyperFeed Employee Plan is currently required to comply with a provision of ERISA or of the Code, but is not yet to be amended to reflect such provision, such plan has been maintained and administered in accordance with the provision) and with the requirements prescribed by any and all statutes, orders, rules and regulations, including but not limited to ERISA and the Code, which are applicable to such HyperFeed Employee Plan. All material reports, returns and similar documents with respect to each HyperFeed Employee Plan required to be filed with any governmental agency or distributed to any HyperFeed Employee Plan participant have been duly timely filed and distributed.

(d) There is no contract, agreement, plan or arrangement that, as a result of the transactions contemplated by this Agreement, would be reasonably likely to obligate HyperFeed or any HyperFeed Subsidiary to make any payment of any amount that would not be deductible pursuant to the terms of Section 162(m) or Section 280G of the Code.

(e) Except as disclosed in writing to Exegy prior to the date hereof, there has been no amendment to, written interpretation or announcement (whether or not written) relating to, or change in employee participation or coverage under, any HyperFeed Employee Plan that would increase materially the expense of maintaining such HyperFeed Employee Plan above the level of the expense incurred in respect thereof for the fiscal year ended December 31, 2005.

(d) All Patents owned by HyperFeed which have been filed with a Patent Office are currently in compliance with formal legal requirements (including payment of filing, examination, and maintenance fees and proofs of working or use), are valid and enforceable, and are not subject to any maintenance fees or taxes or actions except where the failure to have such ownership or license is not reasonably likely to have a HyperFeed Material Adverse Effect.

(e) HyperFeed uses reasonable procedures to keep Trade Secrets owned by HyperFeed confidential, and Trade Secrets owned by HyperFeed have been disclosed only under written agreements that require the recipient to hold such Trade Secrets confidential.

(f) No Patent owned by HyperFeed has been or is now involved in any interference, reissue, reexamination, or opposition proceeding. HyperFeed has not received notification of any potentially interfering patent or patent application of any third party.

Exegy has furnished, or will make available upon request, to HyperFeed copies of the most recent Internal Revenue Service determination letters with respect to each such Exegy Employee Plan.

(a) PICO shall contribute, or shall cause to be contributed, to HyperFeed capital in exchange for shares of HyperFeed Common Stock, in an amount sufficient to cause, as of the Effective Time, HyperFeed to have Minimum Cash, after taking into consideration payment of fees and expenses pursuant to Section 6.7, calculated and determined based upon a mutually acceptable methodology.

(b) Exegy’s stockholders shall contribute, or shall cause to be contributed, to Exegy capital in exchange for shares of Exegy Common Stock, in an amount sufficient to cause, as of the Effective Time, Exegy to have Minimum Cash after taking into consideration payment of fees and expenses pursuant to Section 6.7, calculated and determined based upon a mutually acceptable methodology.

(c) “Minimum Cash” means, for purposes of Section 6.11, the greater of: (1) $5 million unrestricted cash and marketable securities; or (2) the sum of $5 million of unrestricted cash and marketable securities plus the sum of any excess of current liabilities over current assets based on the following definitions: (a) current assets shall mean the current assets set forth on the appropriate entity’s consolidated balance sheet as of the close of business on the Effective Date (the “Closing Balance Sheet”) plus, in the case of HyperFeed, any amounts not then booked and included within current assets with respect to any holdbacks due from Comstock arising from the sale of discontinued operations, and (b) current liabilities shall mean the current liabilities set forth on the Closing Balance Sheet.

(d) Each Closing Balance Sheet will be prepared in accordance with GAAP consistently applied. If it is determined after the Effective Time that the covenants set forth in Section 6.11 were not satisfied as of the Effective Time, Exegy and PICO shall, within 45 days of the Effective Time, contribute an additional amount of capital that will have been sufficient to cause such covenants to be satisfied as of the Effective Time. In addition, to the extent holdbacks due from Comstock and included in Minimum Cash are not received by HyperFeed, then PICO shall contribute such amount to HyperFeed within 30 days of the expiration of any period for the payment of the holdback under the current terms of the documents providing for the holdbacks.
