  &#147;Board&#148;) of LPL Investment Holdings Inc. (the &#147;Company&#148;) amended and restated
  the Company&#146;s by-laws (the &#147;By-Laws&#148; and as amended and restated, the &#147;Amended
  and Restated By-Laws&#148;).&#160; The following is

  <p style="margin:0in 0in .0001pt .25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

  Item 5.03   Amendments to Articles of
  Incorporation or Bylaws; Change in Fiscal Year.
  On and effective June 3, 2008, the Board of Directors (the
  "Board") of LPL Investment Holdings Inc. (the "Company") amended and restated
  the Company's by-laws (the "By-Laws" and as amended and restated, the "Amended
  and Restated By-Laws").  The following is
  a summary of the material changes effected by adoption of the Amended and
  Restated By-Laws:
  Section 2.6
  (Proxies): This section was revised to provide further detail on the use,
  requirements and authorization of proxies, in accordance with the General
  Corporation Law of the State of Delaware ("Delaware GCL"). The changes include
  provisions specifying that unless the terms of a proxy state otherwise, the
  proxy cannot be acted upon more than three years from its date and its
  authorization is unlimited.
  The
  sections relating to advance notice procedures for proposals made by
  stockholders with respect to director nominations and other business have been
  removed.
  Section 2.7
  (Action by Vote): This section was revised to provide that a written ballot is
  not required for the election of directors, to conform to the language in the
  Company's certificate of incorporation.
  Section 2.9
  (Action by Written Consent): This section was added to clarify that unless
  otherwise provided in the Company's certificate of incorporation, the Company's
  stockholders may act by written consent in lieu of a meeting.
  Section 2.10
  (Record Date): This section was revised to add provisions to set the record
  date for the determination of: (i) stockholders entitled to notice of or
  to vote at any meeting of stockholders, (ii) stockholders entitled to
  receive payments of dividends or allotments of other rights, and (iii) stockholders
  entitled to exercise any rights in respect of any change, conversion or
  exchange of stock.
  The
  section relating to the hiring of inspectors of election for purposes of
  reviewing written consents was removed.
  Section 3.2
  (Board of Directors): This section was revised to provide for a standard
  three-year term for each of the Company's directors. The By-Laws previously
  provided for three classes of directors, with each class serving a staggered
  three-year term.
  Section 3.3
  (Regular Meetings): This section was revised to provide that a regular meeting
  of the Board may be held at any time. The By-Laws previously required that a
  regular meeting of the Board be held immediately after the annual meeting of
  stockholders.
  Section 3.11
  (Executive and Other Committees): This section was amended to conform to the
  provisions of Delaware GCL, which allows a committee to exercise all the powers
  of the Board, unless otherwise prohibited by law, by the Company's certificate
  of incorporation or by the Amended and Restated By-Laws.
  Section 3.12
  (Compensation of Directors): This section was added to allow for standard
  compensation and reimbursement of reasonable expenses for members of the
  Company's Board.
  Section 3.13
  (Interested Directors and Officers): This section was added to set forth a
  procedure for the approval of contracts or transactions involving an officer or
  director, in accordance with the requirements of Delaware GCL.
  Section 3.14
  (Removal of Directors): This section was revised to provide that the removal of
  a director is subject to the vote of a majority of the Company's shares
  entitled to vote, as required by Delaware GCL. The By-Laws previously stated
  that a vote of at least 80 percent of the Company's outstanding shares entitled
  to vote was required to remove a director.
  Section 5.1
  (Stock Certificates and Transfers): This section was amended to grant the Board
  the authority to issue uncertificated shares of the Company's capital stock and
  to outline the procedure for the transfer of uncertificated shares on the books
  of the Company.
  2
  Section 8.1
  (Amendments): This section was revised to clarify that the Amended &
  Restated By-Laws can be amended by a vote of the Board, but remain subject to
  repeal or alteration by the Company's stockholders, in accordance with Delaware
  GCL and the Company's certificate of incorporation.
  In addition to the amendments described above, the following sections
  of the Amended and Restated By-Laws include certain other changes to clarify language,
  comply or be consistent with Delaware GCL and various technical edits and
  non-substantive changes: Sections 1.2 (Other Offices), 2.4 (Notice of Meeting),
  2.8 (Inspectors of Election) and 4.2 (Election and Term of Office).
  The Amended and Restated By-Laws of LPL Investment Holdings Inc. are
  filed herewith as Exhibit 3.1 and incorporated herein by reference.
