A COPY OF SUCH AGREEMENT MAY BE OBTAINED, WITHOUT CHARGE, AT THE COMPANY’S PRINCIPAL OFFICE.

The legends set forth above shall be removed and the Company shall issue a certificate without such legends to the holder of the Offered Shares upon which it is stamped, if, unless otherwise required by state securities laws, (i) such Offered Shares are registered for resale under the 1933 Act, (ii) in connection with a sale transaction, such holder provides the Company with an opinion of counsel, in a generally acceptable form, to the effect that a public sale, assignment or transfer of the Offered Shares may be made without registration under the 1933 Act, or (iii) such holder provides the Company with reasonable assurances that the Offered Shares can be sold pursuant to Rule 144 without any restriction as to the number of securities acquired as of a particular date

3

that can then be immediately sold. Such Buyer acknowledges, covenants and agrees to sell the Offered Shares represented by a certificate(s) from which the legends have been removed, only pursuant to (i) a registration statement effective under the 1933 Act or (ii) advice of counsel that such sale is exempt from registration required by Section 5 of the 1933 Act, including, without limitation, a transaction pursuant to Rule 144.

(k)Acknowledgement as to Status of Company. The Buyers acknowledge the following:

i.The Company is delinquent in its reporting obligations under the 1934 Act and has failed to file (a) quarterly reports on Form 10-Q for the quarters ended June 30, 2005, September 30, 2005, and March 31, 2006 and (b) an annual report on Form 10-K for the fiscal year ended December 31, 2005.

ii.The Company’s delinquency in reporting under the 1934 Act is a result of the Company’s review of information relating to its stock option grants as previously disclosed in the Company’s 1934 Act reports and additional historic accounting issues which have surfaced as part of an internal review by management and the re-audit of financial statements for 2004 and 2003 by the Company’s new independent registered public accounting firm. The additional issues include the accounting for investments in and acquisitions of affiliates and subsidiaries, derivative liabilities embedded within the Company’s $7.5 million convertible note issued in December 2004 and certain revenue recognition issues prior to 2005. The Company expects to include restated prior period amounts in its 2005 Annual Report on Form 10-K and its Quarterly Reports on Form 10-Q, for the periods ended June 30, 2005 and September 30, 2005, to reflect additional charges related to stock option grants and to one or more of the additional accounting issues noted above.

iii.The Company can make no representation as to when it will cure such delinquency in its reporting under the 1934 Act.

4

iv.The Company believes that the aforementioned restatement and other failures in its internal controls as described in reports filed by the Company under the 1934 Act constitute material weaknesses under Section 404 of the Sarbanes-Oxley Act of 2002.

v.In connection with the restatement of the Company’s 1999 through 2002 consolidated financial statements in May 2004, the Division of Enforcement of the SEC informed the Company by letter dated July 14, 2004 that it was conducting an informal inquiry. On January 25, 2005, the Company filed a current report on Form 8-K, which indicated that this inquiry was a formal inquiry (the “First 2004 Inquiry”). By letter dated October 28, 2004, the Division of Enforcement of the SEC informed the Company that it was conducting a second informal inquiry, which related to stock options granted by the Company. On February 25, 2005, the Company filed current report on Form 8-K, which indicated that this inquiry was a formal inquiry (the “Second 2004 Inquiry”). On March 14, 2006, SEC Enforcement Staff advised that the Company that it was recommending that the SEC close the First 2004 Inquiry without any action being taken against NYFIX or any individual. However, this recommendation remained subject a formal approval process within the SEC, and, to the Company’s knowledge, was never approved. To the Company’s knowledge both the First 2004 Inquiry and the Second 2004 Inquiry remain open as of the date hereof.

vi.On May 17, 2006, the Company received a grand jury subpoena from the United States Attorney’s Office for the Southern District of New York. The subpoena calls for the production of all documents referring to, relating to or involving the granting of stock options for the time period from 2000 to the present.

vii.Prior to the Buyers’ execution of this Agreement, the Company provided to the Buyers, and Buyers have had an opportunity to review, (A) a copy of a press release of the Company issued prior to the execution of this Agreement, relating to the Company’s unaudited revenues for 2005 and update on accounting restatements, and (B) a draft of a press release relating to the transactions contemplated hereby, which the Company expects to issue prior to the opening of the trading markets on June 30, 2006.  Copies of both such releases are attached hereto as Exhibit 2(k).

Subject to meeting applicable listing requirements (it being understood that the Company does not currently satisfy such listing requirements and may never satisfy such listing requirements), the Company shall use reasonable business efforts to obtain authorization of the Common Stock for quotation on the Nasdaq National Market, the Nasdaq SmallCap Market, The New York Stock Exchange, Inc. or The American Stock Exchange, Inc., as applicable (the “Principal Market”). Once listed for quotation on the Principal Market, neither the Company nor any of its Subsidiaries shall take any action which would be reasonably expected to result in the delisting or suspension of the Common Stock on the Principal Market. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 4(d).

(e)Expenses. At the Closing, the Company shall reimburse the Buyers their expenses (including reasonable attorneys’ fees and expenses) relating to the preparation and negotiation of the Transaction Documents up to an aggregate of $35,000.

(f)Filing of Form 8-K. On or before the fourth (4th) business day following the Closing Date, the Company shall file a Form 8-K with the SEC describing the terms of the transactions contemplated by the Transaction Documents in the form required by the 1934 Act.

(g)Limitation on Filing Registration Statements. From the date hereof through the period ending on the day following the 30th consecutive trading day that a registration statement registering the Offered Shares for resale is declared effective, except as set forth in Schedule 4(g), the Company shall not register any securities other than the Offered Shares and securities on Form S-8 issued in connection with any stock option plan, stock purchase plan, stock bonus plan or other plan for the benefit of employees, officers or directors of the Company.

5. TRANSFER AGENT INSTRUCTIONS.

(a)Delivery of Legended Common Stock. Upon execution of this Agreement, the Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, to issue certificates, registered in the name of each Buyer or its respective nominee(s), for the Offered Shares in such amounts as specified from time to time by each Buyer to the Company (the “Irrevocable Transfer Agent Instructions”), which instructions shall be in the form as provided in Exhibit A hereto. Prior to registration of the Offered Shares under the 1933 Act, all certificates evidencing Offered Shares shall bear the restrictive legend specified in Section 2(g) of this Agreement. The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5, and stop transfer

11

instructions to give effect to Section 2(f) hereof (prior to registration of the Offered Shares under the 1933 Act) will be given by the Company to its transfer agent and that the Offered Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the Registration Rights Agreement.

(b)Delivery of Unlegended Common Stock. After the Offered Shares have been registered for resale, in lieu of delivering physical certificates representing Offered Shares, provided the Company’s transfer agent is participating in the Depositary Trust Company (“DTC”) Fast Automated Securities Transfer program, on the written request of a Buyer who shall have previously instructed its broker to confirm such request to the Company’s transfer agent, the Company shall cause its transfer agent to transmit electronically the Offered Shares to the Buyer by crediting the account of the Buyer’s prime broker with DTC through its Deposit Withdrawal Agent Commission system no later than the date upon which the Company is required to deliver shares to the Buyer under the terms of this Agreement. Nothing in this Section 5 shall affect in any way each Buyer’s obligations to comply with all applicable prospectus delivery requirements, if any, upon resale of the Offered Shares. If a Buyer provides the Company with an opinion of counsel, in a generally acceptable form, to the effect that a public sale, assignment or transfer of the Offered Shares may be made without registration under the 1933 Act or the Buyer provides the Company with an opinion of counsel, in a generally acceptable form, to the effect that the Offered Shares can be sold pursuant to Rule 144 without any restriction as to the number of securities acquired as of a particular date that can then be immediately sold, the Company shall permit the transfer, and promptly instruct its transfer agent to issue one or more certificates in such name and in such denominations as specified by such Buyer and without any restrictive legend.

(c)Timing of Delivery. Whenever the Company is required to deliver Offered Shares under the Transaction Documents, whether with or without a restrictive legend, such delivery shall be made within three (3) business days of the day that request is made for delivery of such Offered Shares.

Attn: John Boryczki

Dear Sir:

Reference is made to that certain Securities Purchase Agreement, dated June 29, 2006 (the “Agreement”), by and among NYFIX, INC., a Delaware corporation (the “Company”), and the investors named on the Schedule of Buyers attached thereto (collectively, the “Holders”), pursuant to which the Company is issuing to the Holders an aggregate of up to 2,713,000 shares of Common Stock, $0.001 par value per share (“Common Stock”).

This letter shall serve as our irrevocable authorization and direction to you to promptly issue shares (the “Shares”) of Common Stock of the Company to the Holders in the amounts specified opposite each Holder’s name on Exhibit I attached hereto, effective as of ________________, 2006. Please deliver the certificates directly to the Holders at the address specified opposite each Holder’s name on Exhibit I attached hereto.

So long as you have previously received (a) written confirmation from counsel to the Company that a registration statement covering resales of the applicable Shares has been declared effective by the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “1933 Act”), and (b) a copy of such registration statement, then you shall issue the certificates representing the Shares within two business days after your receipt of a written request of a Holder or the Exercise Notice (and in instances where certificates evidencing Shares have already been issued with a Securities Act legend, upon return of such legended certificates for cancellation by you), and such certificates shall not bear any legend restricting transfer of the Shares thereby and should not be subject to any stop-transfer restriction; provided, however, that if such Shares are not registered for resale under the 1933 Act, then the certificates for such Shares shall bear the following legend:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE PROVISIONS OF A SECURITIES PURCHASE AGREEMENT BETWEEN THE COMPANY AND THE HOLDER, WHICH MAY RESTRICT THE TRANSFER OF SUCH SECURITIES IN CERTAIN CIRCUMSTANCES. A COPY OF SUCH AGREEMENT MAY BE OBTAINED, WITHOUT CHARGE, AT THE COMPANY’S PRINCIPAL OFFICE.”

All Shares that are to be issued without a restrictive legend shall, upon request from Holder, be issued electronically using the Depositary Trust Company (“DTC”) Fast Automated Securities Transfer program so long as you subscribe to such system. A form of written confirmation from counsel to the Company that a registration statement covering resales of the Shares has been declared effective by the SEC under the 1933 Act is attached hereto as Exhibit II.

binding obligations of each party thereto (other than the Company); and (xvi) the legal capacity of each natural person signatory to any of the documents reviewed by us.

In rendering this opinion, we have made no independent investigation of the facts referred to herein and have relied, for the purpose of rendering this opinion, exclusively on the truth and accuracy of the representations and warranties set forth in the Securities Purchase Agreement, and the statements and certificates of the Company’s officers and public officials, which representations and warranties, statements and certificates we assume are true, accurate and correct in all respects.

Based upon the foregoing, and upon an examination of such questions of law as we have considered necessary or appropriate, and subject to the assumptions, exceptions, qualification and limitations set forth herein, we advise you that in our opinion:

1. The Company has been duly incorporated and is validly existing and in good standing under the laws of the State of Delaware. The Company has all requisite power to own, lease and operate its properties, assets and business and to carry on its business as currently conducted and as proposed to be conducted.

2. The authorized capital stock of the Company consists of 60,000,000 shares of Common Stock, $0.001 par value per share, and 5,000,000 shares of Preferred Stock, $1.00 par value per share. As of the Closing, the Offered Shares will be free of any liens, claims or encumbrances in favor of the Company and free of restrictions on transfer other than as set forth in the Transaction Documents or under applicable state and federal securities laws. The Offered Shares have been duly authorized and, upon issuance pursuant to the terms of the Securities Purchase Agreement, will be validly issued, fully paid, nonassessable and free of any liens in favor of the Company.

3. The Company has all requisite corporate power and authority to enter into, deliver and perform each of the Transaction Documents to which it is a party.

4. The execution and delivery of the Transaction Documents and the performance by the Company of its obligations thereunder and the issuance of the Offered Shares do not, and will not, conflict with or result in a violation of any federal, New York or Delaware corporate law, rule or regulation applicable to the Company or any provision of the Certificate of Incorporation or Bylaws of the Company, each as amended through the date hereof.

5. No consent, approval or authorization of or designation, declaration, notification or filing with, any governmental authority on the part of the Company is required in connection with the valid execution, delivery and performance of the Transaction Documents, or the offer, sale or issuance of the Offered Shares, or the consummation of any other transaction contemplated by the Transaction Documents except for consents, approvals, authorizations, declarations or filings that have already been made or will be made within applicable time periods.

6. Assuming your representations and warranties contained in the Securities Purchase Agreement are true and correct, the offer, sale and issuance of the Offered Shares constitute transactions exempt from the registration requirements of Section 5 of the Securities Act of 1933, as amended.

(c)the qualification that certain rights, remedies, waivers and procedures contained in the Transaction Documents may be limited or rendered unenforceable by applicable laws or judicial decisions governing such provisions, but such laws and judicial decisions do not, in our opinion, render the Transaction Documents, as a whole, unenforceable or make the remedies and procedures that are available to the parties legally inadequate for the practical realization of the principal benefits purported to be provided to them by the Transaction Documents;

(d)the qualification that certain provisions contained in the Transaction Documents may be unenforceable in whole or in part if such enforcement would be unreasonable under the circumstances;

(e)the possible requirement that actions taken, or not taken, by any party pursuant to the Transaction Documents he taken, or not taken, in good faith;

(h)the qualification that certain provisions of any such document to the effect that rights or remedies are not exclusive, that every right or remedy is cumulative and may be exercised in addition to any other right or remedy, that the election of some particular remedy does not preclude recourse to one or more others or that failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy, may be unenforceable in whole or in part;

(1)the unenforceability under certain circumstances of any provision insofar as it provides for the payment or reimbursement of costs and expenses of indemnification for claims, losses or liabilities in excess of a reasonable amount; and

(m)the unenforceability, in certain circumstances, of consent to jurisdiction clauses and forum selection clauses.

C.We express no opinion as to the validity or enforceability of the indemnification and contribution provisions of the Registration Rights Agreement.

NYFIX REPORTS UNAUDITED DIVISIONAL REVENUES FOR 2005 BY QUARTER AND FOR THE FULL YEAR

UPDATE ON ACCOUNTING RESTATEMENTS

UNAUDITED DIVISIONAL REVENUES FOR FIRST QUARTER 2006 REPORTED

New York, NY June 29, 2006: NYFIX, Inc. (Pink Sheets: NYFX). NYFIX, a leader in technology solutions for the financial marketplace, announced today its divisional revenues for 2005 by quarter and for the full year, an update on previously announced accounting restatements and divisional revenues for the first quarter of 2006.

In late 2005, NYFIX re-aligned its business into four operating divisions: FIX Network, Order Management Systems (OMS), Transaction Services and Order Book Management Systems (OBMS). The results of these divisions will be separately disclosed in the Company’s periodic filings with the SEC. The FIX Network Division provides software to enable global financial institutions to utilize the industry established Financial Information Exchange Protocol for messaging, monitoring and processing transaction information. The FIX Network segment also provides network connectivity between institutional investors, broker-dealers and exchanges. The Transaction Services segment is comprised of three U.S. registered broker-dealer subsidiaries: NYFIX Millennium, NYFIX Transaction Services and NYFIX Clearing. NYFIX Millennium, an alternative trading system registered under SEC Regulation ATS, provides anonymous matching and routing of U.S. equity securities. NYFIX Transaction Services provides direct electronic market access and algorithmic trading products. NYFIX Clearing clears trades on behalf of NYFIX Millennium and NYFIX Transaction Services and operates a matched-book stock borrow/stock loan business. The OMS segment provides software applications for desktop and wireless handheld management of New York Stock Exchange and Nasdaq listed trading activities. The OMS desktop platform provides clients with access to the Company’s connectivity and transaction services. The OBMS segment specializes in electronic trading solutions for the global derivatives market and offers order management workstations and exchange interfaces. Historical results have been recast to reflect the performance of these divisions in prior periods.

NYFIX cautions that the financial information noted below is unaudited and such amounts may differ from those included in quarterly and annual SEC filings. Due to the review of stock option and warrant grants noted below and the evaluation of the complex accounting implications of the results of that review, NYFIX is not able to provide GAAP results at this time. The Company

does expect to report losses for the full year 2005 and the first quarter 2006 when it ultimately reports. The Company will provide detailed results once this evaluation has been completed.

The average number of symbols matched daily was 577 for the fourth quarter 2005, compared to 202 for the fourth quarter 2004. For full year 2005, the average daily matched volume in NYFIX Millennium was 11.6 million shares, an increase of 68% over the average daily matched volume of 6.9 million shares during the full year 2004. The average number of symbols matched daily was 420 for the full year 2005, compared to 200 for full year 2004. Included in the volume and symbol figures noted above are conditional orders that are executed against pass-through orders and other conditional orders, and third-market trades crossed by clients and reported by NYFIX to Nasdaq.

Update on Accounting Restatements

NYFIX has substantially completed the previously announced review of historical stock option grants and is still evaluating the complex accounting implications on previously reported results. Since the accounting for common stock purchase warrants is similar to that for stock options, NYFIX expanded its review to include such awards. NYFIX has expended significant resources

as part of its process to conform its accounting for stock options and warrants to GAAP. During the year ended December 31, 2005 and the quarter ended March 31, 2006, NYFIX incurred costs of $3.1 million and $3.9 million, respectively, related to the SEC inquiries, the financial restatements and related litigation. The Company has performed a detailed forensic review of over 1,400 awards to more than 500 grantees. At times the Company retained in excess of 60 contract lawyers and accountants combined to review hundreds of thousands of documents, such as Board and Committee meeting minutes, resolutions, schedules and emails, and meta-data for such documents, to respond to SEC information requests and to determine the appropriate dates to measure the accounting impact of grants and exercises. The Company’s review has identified a number of accounting issues not previously included in the $16.4 million restatement for stock option compensation included in the 2004 Annual Report on Form 10-K. The Company expects the accounting consequences of these issues to materially exceed the $2.0 million of estimated additional stock option compensation announced in October 2005. Some of the more significant issues include the following:

• Grants where there is insufficient basis to rely on the process and documentation to reasonably ascertain a date to measure the accounting impact.

• Grants where there was a failure to complete the option grant process by the effective date of the grant with respect to the number of shares to be issued, amounts allocated to grantees and/or the subsequent identification of new grantees.

• Grants for which there were subsequent modifications.

• Non-recourse loans issued by certain Officers and Directors for the exercise of options and warrants.

• As previously announced, NYFIX will restate previously reported results for other issues in addition to stock option and warrant compensation. These issues were identified during an overall internal accounting review by management and the ongoing re-audit of financial statements for 2004 and 2003 by Friedman, LLP, the independent registered public accounting firm appointed by the Company’s Audit Committee in November 2005, and include the following (all amounts unaudited):

• $4.0 million, net, in additional pre-tax charges associated with the 2002 acquisition of an initial interest in Renaissance Trading Technologies, LLC (“Renaissance”) and the 2003 acquisition of the remaining interest in Renaissance not previously held by the Company. Gross charges of $2.5 million and $2.0 million for the years ended December 31, 2003 and 2002 are offset by reductions to amortization expense for an intangible asset left at cost of $0.1 million, $0.3 million and $0.2 million, respectively, for the first quarter 2005 and the full years 2004 and 2003.

• $1.6 million, net, in additional pre-tax charges associated with the 2002 acquisition of an initial interest in EuroLink Network, Inc. (“EuroLink”) and the 2004 acquisition of the remaining interest in EuroLink not previously held by the Company. Of this amount, $0.1 million, $0.7 million and $0.8 million, respectively, relate to the years ended December 31, 2004, 2003 and 2002.

• $2.0 million pre-tax reversal of revenue recorded in 2001 with respect to transactions with an entity operated by substantially the same principals as EuroLink prior to the Company’s initial investment in EuroLink in 2002.

• $0.9 million pre-tax net reversal of revenue recorded by the London branch office of the Company’s NYFIX Overseas subsidiary related to the timing of delivery of product and service periods covered. Of this net amount, $0.1 million is an increase to revenues for the first quarter 2005, $0.4 million is a decrease to revenues for the full year 2004, $0.1 million is an increase to revenues for 2003 and $0.7 million is a decrease to revenues for the year ended December 31, 2002.

• $0.2 million pre-tax charge in the first quarter of 2005 related to the Company’s $7.5 million convertible note for the amortization of the debt discount established for embedded derivatives and the fair value adjustments on those embedded derivatives.

• The Company has established a valuation allowance for deferred tax assets effective December 31, 2000. The Company had not previously reserved for deferred tax assets until the third quarter of 2004. As a result of this restatement, tax benefits of $3.7 million previously recorded through additional-paid-in capital and on acquisitions have been reversed and therefore have not been reserved for through operations. In addition, primarily because of the additional expense recorded for the losses incurred by Renaissance, a net deferred tax liability recorded through operations has been reduced by $1.2 million.

NYFIX previously only recorded a portion of the operating losses of Renaissance and EuroLink based on the percentage voting interest it held in these entities under the equity method. Since NYFIX provided substantially all of the funding for these entities through its investments and through loans and advances, historical results have been restated to absorb 100% of these operating losses. Prior to making its investment in EuroLink in March 2002, NYFIX previously recorded $2.0 million of revenue in 2001 for transactions with IMX Group, LLC (“IMX”). IMX had minimal assets other than cash from a $0.5 million loan from NYFIX and was operated by substantially all of the same principals who later operated EuroLink. The $2.0 million liability on the books of IMX was transferred to EuroLink in March 2002 and was paid to NYFIX out of the $4.0 million investment made by NYFIX in EuroLink in March 2002.

Unaudited Revenues for First Quarter 2006

Revenues for the first quarter 2006 were $25.4 million, an increase of 7% over the $23.8 million of restated revenues for the first quarter 2005.

Revenues from the Company’s four operating divisions were as follows:

	Quarter ended March 31,
(in millions)	2006			2005
				(As Restated)
FIX Network	$	11	.3	$	8	.9
OMS	$	5	.2	$	5	.9
Transaction Services	$	7	.3	$	6	.2
OBMS	$	1	.6	$	2	.8
Total Revenues (unaudited)	$	25	.4	$	23	.8

Adjustments to Exercise Prices for Option Grants to Officers and Directors

In June 2006, the Company increased the exercise prices of certain grants still outstanding to certain Directors and Officers where, based on the state of the documentation or process involved, there is doubt as to the appropriateness of the Company’s prior practices regarding grant date and/or exercise price. The Company intends to request additional payment from a former Director and a former Officer where similar doubts exist on grants that have been exercised.

Although Robert Gasser, NYFIX’s current Chief Executive Officer, was not involved in the granting process when these awards were issued, he has voluntarily agreed to be held to the same standard. As a result, the Company has increased the exercise prices on certain grants made to him and has voided an award given to him where the date of grant could not be ascertained.
