Item 5.02.   Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

Compensatory Arrangements of Certain Officers.  LPL Investment Holdings Inc. (the “Company”) had a change of compensatory arrangements that was approved by the Board of Directors on November 19, 2008 in which the Board of Directors approved the Company’s new 2008 Nonqualified Deferred Compensation Plan (the “Plan”). Esther M. Stearns, President and Chief Operating Officer, Steven M. Black, Managing Director and Chief Risk Officer, and William E. Dwyer, Managing Director and President of Independent Advisor Services, are eligible to participate in the Plan and may elect to exchange all of their stock options that will expire in 2009 or 2010 under the Company’s 1999 Stock Option Plans, as amended (currently in the form of the Company’s 2005 Stock Option Plan for Non-Qualified Stock Options and 2005 Stock Option Plan for Incentive Stock Options; collectively, the “1999 Stock Option Plans”), for accounts under the Plan.

The Plan is attached hereto as Exhibit 10.1 and is hereby incorporated by reference.

Description of the Plan

Purpose.   The purpose of the Plan is to permit employees and former employees of the Company and its subsidiaries that hold stock options issued under the Company’s 1999 Stock Option Plans that expire in 2009 or 2010 to exchange their options for stock units under the Plan that are paid out at a later date in the form of shares of Company common stock.

Administration.  The Plan is administered by the Board of Directors of the Company, or such other committee as may be appointed by the Board of Directors to administer the Plan (the “Administrator”).  The Administrator has all powers necessary to administer the Plan, including discretionary authority to determine eligibility for benefits and to decide claims under the Plan.

Eligibility.  Current and former employees of the Company and its subsidiaries that hold stock options under the 1999 Stock Option Plans that are set to expire in 2009 or 2010 (the “Expiring Options”) may make a one-time election to participate in the Plan.

Compensation Eligible for Deferral under the Plan.  Participants may elect to cancel their Expiring Options in exchange for stock units held in an account under the Plan.  Each stock unit is a bookkeeping entry of which one stock unit is the economic equivalent of one share of Company common stock.

Accounts Maintained under the Deferred Compensation Plan.  The Administrator will create an account on a participant’s behalf to which the participant’s initial balance will be credited, which will then be converted into stock units.  A participant’s initial balance is an amount equal to the fair market value on December 31, 2008 of the shares underlying the stock options the participant has elected to defer, less the aggregate exercise price of these options.  The initial number of stock units in a participant’s account will equal his or her initial balance divided by the fair market value of a share of Company common stock on December 31, 2008.

A participant’s account will be adjusted if cash dividends are paid on Company common stock while the participant is a current employee of the Company or its subsidiaries by crediting the account with an amount equal to the cash dividend paid, multiplied by the number of stock units in the account on the day the cash dividend is paid.  The amount credited to the account will then be converted into stock units, calculated by dividing the aggregate amount credited to the account by the fair market value of a share of Company  common stock on the date the dividend is paid.  Fair market value is determined by the Board of Directors in good faith.

2

Elections to Participate in the Plan Cannot be Modified or Revoked.  A Participant’s election to exchange his or her Expiring Options for deferred compensation is not revocable and cannot be modified once the deadline for making the election is passed. In addition, once a participant makes an election the participant cannot exercise the Expiring Options with respect to which the election was made.

Distribution of Account Balances.  A participant’s account balance will be distributed at the earliest to occur of: (a) the participant’s death; (b) the participant’s disability; (c) a change in control of the Company, or (d) a date in 2012 to be determined by the Board of Directors.  A “change in control” will occur if, for example, a person (or persons acting as a group) acquires more than 50% of the stock of the Company or substantially all of the Company’s assets are sold.  A “change in control” does not include an initial public offering of common stock of the Company.  With respect to payments made under (a), (b) and (c) above, the payments will be made within 90 days of the event that triggers distribution. With respect to payments made under (d) above, the payments will be made by December 31, 2012.  Distributions will be made in the form of whole shares of common stock equal to the number of stock units allocated to the participant’s  account (rounded to the nearest whole number).

Vesting.   Participants are 100% vested in their accounts. However, if a participant is terminated for cause, the participant’s entire account will be forfeited.

Amendment and Termination.  The Administrator can amend or terminate the Plan for any purpose, at any time, provided that the Administrator obtains the consent of participants for any amendments to the Plan that materially and adversely affect the rights of the participants under the Plan.

The Company’s Obligation under the Plan.  The Company’s obligation to distribute shares in satisfaction of a participant’s benefit under the Plan is contractual only.

4.             Participation.

a.             An employee or former employee of the Company holding stock options expiring in 2009 or 2010 that were issued under the Company’s 1999 Stock Option Plan who submits to the Administrator a completed written election to defer the Elected Options shall participate in the Plan on the terms and conditions set forth herein.  Such election shall be made at the time and in the manner determined by the Administrator, to become effective on the Effective Date.

b.             A Participant’s participation in the Plan shall continue until the entire balance in the Participant’s Account has been paid in full.

5.             Accounts.

(a)           The Administrator shall establish an Account for each Participant on its books to which there shall be credited the Initial Balance with respect to the Participant.  The Account shall be represented by Stock Units.  The initial number of Stock Units in the Participant’s Account shall be equal to the Initial Balance divided by the Fair Market Value of the Common Stock on the Effective Date.

(b)           In the event a cash dividend is paid on the Common Stock while a Participant is currently employed by the Company, each Participant’s Account will be adjusted by crediting an amount equal to the amount of the cash dividend paid multiplied by the number of Stock Units in the Participant’s Account on the day the cash dividend is paid (the “Aggregate Dividend

4

Amount”) to the Participant’s Account.  The amount credited to a Participant’s Account will then be converted into Stock Units, calculated by dividing the Aggregate Dividend Amount by the Fair Market Value of the Common Stock on the date such cash dividend is paid.

(c)           In the event of any stock split, reverse stock split, stock dividend, recapitalization or similar change affecting the Common Stock, the Administrator shall make such adjustment as it deems appropriate in the number of Stock Units then credited to an Account of the Participant in order to maintain the proportional interests of the Participant and to preserve the value of the Account in light of such change affecting the Common Stock.

(d)           The Participant’s Stock Units do not carry voting rights and the Participant has no rights as a stockholder of the Company or equity interest or ownership in the Company by virtue of participation in the Plan.

(e)           The Participant’s Account shall be nonforfeitable, except as otherwise provided herein.

(f)            Not less frequently than annually, the Administrator will furnish the Participant with a statement setting forth the number of Stock Units credited to the Participant’s Account.

6.             Distribution.

(a)           On the Payment Date, subject to Section 6(b) herein, the Administrator shall pay to a Participant an amount equal to the number of Stock Units in the Participant’s Account multiplied by the Fair Market Value on the day preceding the Payment Date, such amount being payable in Common Stock.

(b)           In the event that the Company terminates a Participant’s employment for Cause, the Participant’s entire Account balance shall be forfeited and the Participant shall have no rights with respect thereto.

7.             Designation of Beneficiary. A Participant may designate or change the designation of a beneficiary or beneficiaries to receive any payment due hereunder upon the Participant’s death by filing a written designation with the Administrator.  The Administrator shall be bound by the last designation filed with it by the Participant.  In the absence of such designation of a beneficiary by the Participant, or if no beneficiary so designated shall survive the Participant, the Participant’s beneficiary shall be the Participant’s estate.  Any amounts due hereunder payable to the beneficiary or beneficiaries shall be made on the same terms and shall be subject to the same conditions as if such amounts were paid to the Participant.

8.             Employment Rights.  Participation in the Plan shall not create any right of the Participant to continued employment with the Company or limit the right of Company to terminate the Participant’s employment at any time.  Except to the extent required by applicable law that cannot be waived, the loss of the Account shall not constitute an element of damages in the event of termination of the Participant’s employment even if the termination is determined to be in violation of an obligation of the Company to the Participant by contract or otherwise.

5

9.             Contractual Obligation.  The obligations of the Company hereunder shall be contractual only. The Participant shall rely solely on the unsecured promise of the Company and nothing herein shall be construed to give the Participant or any other person or persons any right, title, interest or claim in or to any specific asset, fund, reserve, account or property of any kind whatsoever owned by the Company.

10.           No Assignment. No right or benefit or payment under the Plan shall be subject to assignment or other transfer nor shall it be liable or subject in any manner to attachment, garnishment or execution.

11.           Withholding.  The distribution of a Participant’s Account balance is conditioned upon full satisfaction by the Participant of all tax withholding requirements with respect to the Account balance.  Payment of applicable withholding taxes is the obligation of the Participant; provided, however that a Participant may not satisfy tax withholding obligations through the redemption by the Company of Stock Units or Common Stock under the Plan.  The Administrator will prescribe such rules for the withholding of taxes as it deems necessary.

12.           Amendment or Termination. The Administrator may at any time or times amend the Plan for any purpose which may at the time be permitted by law, and may at any time terminate the Plan; provided, that except as otherwise expressly provided in the Plan the Administrator may not, without the Participant’s consent, amend the Plan so as to affect materially and adversely the Participant’s rights under the Plan.
