                              EXPLANATORY STATEMENT

     On September 3, 2002, Investment Technology Group, Inc. ("ITG") acquired
Hoenig Group Inc. ("Hoenig") through the merger of ITG's wholly-owned subsidiary
Indigo Acquisition Corp. with and into Hoenig, with Hoenig surviving the merger.
As a consequence of the merger, each share of Hoenig common stock was converted
into (i) the right to receive, without interest, $11.35 (the "Cash Merger
Consideration") and (ii) one contingent payment right for a pro rata share of
any future distributions from an escrow account set up in connection with the
pursuit of certain insurance and other claims related to a trading loss and
unauthorized trading activity suffered at Hoenig's U.K. subsidiary. Options to
purchase Hoenig common stock were either cashed-out or rolled over as follows.
All cash-out options were canceled, and holders of cash-out options with an
exercise price below the Cash Merger Consideration received (i) an amount in
cash, without interest, equal to the product of (x) the excess of the Cash
Merger Consideration over the exercise price per share of such cash-out option
times (y) the number of shares of Hoenig common stock subject to such cash-out
option and (ii) the number of contingent payment rights as is equal to the
number of shares of Hoenig common stock subject to such cash-out option. Each
rollover option was converted into (x) except for specified rollover options,
the number of contingent payment rights as is equal to the number of shares of
Hoenig common stock subject to such rollover option and (y) an option to
purchase shares of ITG common stock on terms substantially identical to those in
effect immediately prior to the merger under the terms of the stock option plan
or other agreement or award pursuant to which such Hoenig stock option was
granted; provided, however, that from and after the merger, (i) each rollover
option assumed by ITG became exercisable solely to purchase shares of ITG common
stock, (ii) the number of shares of ITG common stock purchasable upon exercise
of each rollover option became equal to the number of shares of Hoenig common
stock that were purchasable under such rollover option immediately prior to the
merger multiplied by the exchange ratio and rounded down to the nearest whole
share and (iii) the per share exercise price under each rollover option was
adjusted by dividing the per share exercise price of such rollover option
immediately prior to the merger by the exchange ratio, and rounded up to the
nearest whole cent. This Registration Statement covers shares of ITG common
stock issuable upon the exercise of the rollover options.

not be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.

ITEM 4. DESCRIPTION OF SECURITIES.

     Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     The legality of the shares of Common Stock offered hereby has been passed
upon for the Registrant by P. Mats Goebels, General Counsel and Secretary of the
Registrant. As of September 3, 2002, Mr. Goebels beneficially owned 9,898 shares
of the Company's Common Stock and options to purchase 12,500 additional shares.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Company is incorporated under the laws of the State of Delaware.
Sections 102 and 145 of the Delaware General Corporation Law (the "DGCL") set
forth the conditions and limitations governing the indemnification of officers,
directors and other persons by Delaware corporations.





     Generally, Section 145 of the DGCL provides that a Delaware corporation
shall have the power to indemnify any person who was or is a party or is
threatened to be made a party to any action, suit or proceeding (except actions
by or in the right of the corporation) by reason of the fact that such person is
or was a director, officer, employee or agent of the corporation against all
expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or her in connection with such action, suit or
proceeding if he or she acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. In addition, a Delaware corporation may
similarly indemnify such person for expenses actually and reasonably incurred by
him or her in connection with the defense or settlement of any action or suit by
or in the right of the corporation, provided such person acted in good faith and
in a manner he or she reasonably believed to be in the best interests of the
corporation, and, in the case of claims, issues and matters as to which such
person shall have been adjudged liable to the corporation, provided that the
Court of Chancery of the State of Delaware or the court in which such action or
suit was brought shall have determined upon application, that, despite the
adjudication of liability by in view of all of the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which such court shall deem proper. To the extent that a present or former
director or officer of a Delaware corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding described above, or in
defense of any claim, issue or matter therein, such person shall be indemnified
against expenses actually and reasonably incurred by such person in connection
therewith.

     Generally, Section 102(b)(7) of the DGCL provides that the certificate of
incorporation of a Delaware corporation may contain provisions eliminating or
limiting the personal liability of a director to a corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director;
provided that such provision may not eliminate or limit the liability of a
director (i) for any breach of the director's duty of loyalty to the corporation
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or knowing violation of law, (iii) under Section
174 of Title 8 of the DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. No such provision may eliminate or limit
the liability of a director for any act or omission occurring prior to the date
which such provisions became effective.

     Section 145 of the DGCL provides that a Delaware corporation shall have the
power to purchase and maintain insurance of behalf of any person who is or was a
director, officer, employee or agent of the corporation against any liability
asserted against such person and incurred by such person in any such capacity,
or arising out of such person's status as such, whether or not the corporation
would have the power to indemnify such person against the same pursuant to the
provisions of the DGCL.

     Our certificate of incorporation, as amended, provides for indemnification
of directors and officers for liabilities and expenses incurred in defending
actions brought against them in such capacities. Our certificate of
incorporation provides that we shall indemnify our directors and officers to the
maximum extent now or hereafter permitted by law.

     We maintain directors' and officers' liability insurance covering all of
our directors and officers against claims arising out of the performance of
their duties.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

     Not applicable.

ITEM 8. EXHIBITS.

     See Exhibit Index.





ITEM 9. UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

     1. To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

          (i) to include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

          (ii) to reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective registration statement; or

          (iii) to include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement;

provided, however, that paragraphs (1)(i) and (ii) do not apply if the
Registration Statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed by the registrant pursuant to Section 13 or Section 15(d)
of the Securities Exchange Act of 1934 that are incorporated by reference in the
Registration Statement.

     2. That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof; and

     3. To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     That, for purposes of determining any liability under the Securities Act,
each filing of the registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in this registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 6 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemni-





fication by it is against public policy as expressed in the Securities Act and
will be governed by the final adjudication of such issue.

        Option Plan
        ----------------------------------------------------------------------

Ladies and Gentlemen:

     I am General Counsel to Investment Technology Group, Inc., a Delaware
corporation (the "Company"). The Company is filing a Registration Statement on
Form S-8 (the "Registration Statement") with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Securities Act"), relating to 61,261 shares of the Company's common stock (the
"1996 Option Plan Registered Shares"), par value $.01 per share, offered under
Hoenig Group Inc.'s ("Hoenig") 1996 Long-Term Stock Incentive Plan, as amended
and restated (the "1996 Option Plan"), 35,750 shares of the Company's common
stock (the "1994 Option Plan Registered Shares"), par value $.01 per share,
offered under Hoenig's 1994 Stock Option Plan, as amended and restated (the
"1994 Option Plan") and 2,437 shares of the Company's common stock (the "1991
Option Plan Registered Shares"; and together with the 1996 Option Plan
Registered Shares and the 1994 Option Plan Registered Shares, the "Registered
Shares"), par value $.01 per share, offered under Hoenig's 1991 Stock Option
Plan, as amended and restated (the "1991 Option Plan"; and together with the
1996 Option Plan and 1994 Option Plan, the "Plans").

     In connection with this opinion, I have examined the Registration
Statement, the Certificate of Incorporation and Bylaws of the Company, certain
of the Company's corporate proceedings as reflected in its minute books, the
Plans and such other records as I have deemed relevant. In addition, I have made
such other examinations of law and fact as I have deemed appropriate in order to
form a basis for the opinion hereinafter expressed. In my opinion, the
Registered Shares that may be originally issued by the Company in connection
with the Plans, when and to the extent issued in accordance with the terms of
the Plans and the resolution authorizing the Plans for a price per share not
less than the par value thereof, will be duly authorized, validly issued, fully
paid and non-assessable.

     In rendering this opinion, I express no opinion as to the laws of any
jurisdiction other than the laws of the United States, the laws of the State of
New York and the Delaware General Corporation Law.

     I hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement. In giving such opinion and consent, I do not thereby
admit that I am acting within the category of persons whose consent is required
under Section 7 of the Securities Act or the rules and regulations of the
Commission thereunder.

                                   Very truly yours

                                   /s/ P. Mats Goebels
                                   Managing Director, General Counsel
                                   And Secretary
