ARTICLE 4
COMPENSATION MATTERS
AND NON-ERISA BENEFIT ARRANGEMENTS

     4.1 Assumption of Individual Agreements. Effective on the Transfer Date for any and each Transferred Employee, Cal Dive will assume and/or be responsible for satisfying any and all obligations and liabilities (fixed or contingent) of Helix or any Helix Entity incurred or arising under or in connection with any individual employment, retention, separation, consulting, representation or other personal services-related agreements (together with any ancillary trust or other agreements) made directly or indirectly with or for the benefit of such Transferred Employee; provided, however, that, following the applicable Transfer Date, Helix and the other Helix Entities shall retain any rights which it or any of them would have had following the termination of any such agreement, determined as if the agreement terminated immediately prior to the Transfer Date, except to the extent that the exercise of such rights by Helix and the other Helix Entities following the Transfer Date would adversely affect the rights of any Cal Dive Entity under such agreement. Cal Dive shall indemnify Helix and the Helix Entities and their affiliates and hold them and each of them harmless from, against and with respect to any claim, liability or expense asserted or imposed against it or any of them under or in connection with any of the agreements described in the first sentence of this Section 4.1.

     4.2 Stock Incentive Plans.

     (a) Outstanding Helix Stock Options. Under the terms of the Helix Energy Solutions Group, Inc. 2005 Long-Term Incentive Plan and/or the 1995 Long Term Incentive Plan of Helix Energy Solutions Group, Inc. (the “Helix Stock Incentive Plans”), upon the Trigger Date the Transferred Employees shall be deemed to have terminated employment for all purposes of the Helix Stock Incentive Plans. Notwithstanding such provisions, Helix, in its sole discretion, may elect for any Transferred Employee that any or all stock options granted to such Transferred Employee under the Helix Stock Incentive Plans will continue under their present terms and the terms of the plans under which they were granted and shall be exercisable for shares of common stock of Helix. In the event Helix does elect that any stock options granted to any Transferred Employee shall continue under the terms of the Helix Stock Incentive Plans, the parties hereby agree that upon the Trigger Date all such stock options granted to Transferred Employees under the Helix Stock Incentive Plans and outstanding as of the Trigger Date shall remain exercisable until the earlier of (1) the expiration of the general term of the option or (2) the later of (i) December 31 of the calendar year in which the Trigger Date occurs, or (ii) the 15^th day of the third month after the expiration of the 60-day period commencing on the Trigger Date. In addition, with respect to any such options that Helix has elected to continue under the terms of the Helix Stock Incentive Plan(s), at Helix’s sole discretion, Helix may agree on an employee by employee basis that to the extent necessary to avoid the forfeiture of any such unvested stock options due to the operation of the immediately preceding sentence, the vesting of all such unvested stock options granted to Transferred Employees under the Helix Stock Incentive Plans and outstanding as of the Trigger Date shall be accelerated and such stock options shall become fully vested on the Trigger Date. If, prior to the lapse or forfeiture of a stock option granted to a Transferred Employee under a Helix Stock Incentive Plan the Department of Treasury issues guidance in which it expressly takes the position that a stock option that would have otherwise expired early due to termination of employment may remain exercisable for its general term without being subject to section 409A of the Code, Helix shall take such actions as are necessary to amend such stock option granted to a Transferred Employee under a Helix Stock Incentive Plans with respect to which Helix has elected that such option should continue to specify that such stock option will remain exercisable in accordance with its original provisions except that employment with a Cal Dive Entity shall be treated in the same manner as if it were employment with a Helix Entity. In consideration of the foregoing agreements in this Section 4.2(a), following the Trigger Date, Cal Dive shall pay to Helix monthly service fees (“Stock Option Service Fees”). The Stock Option Service Fee for a month shall be an amount equal to the sum of (x) the aggregate third party costs incurred by Helix during the month in connection with the administration of the stock options granted to Transferred Employees under the Helix Stock Incentive Plans and (y) the total costs and expenses recognized, accrued or otherwise incurred by Helix during the month for financial accounting purposes with respect to the stock options granted to Transferred Employees under the Helix Stock Incentive Plans and/or the agreements contained in the foregoing provisions of this Section 4.2(a) (the costs and expenses described in this clause (y) are referred to herein as the “Stock Option Accounting Costs and Expenses”). Helix’s determination concerning any amount of the Stock Option Accounting Costs and Expenses shall be binding on the parties hereto. The Stock Option Service Fees will be

charged to Cal Dive on a monthly basis. Cal Dive shall pay to Helix the Stock Option Service Fee for a month within 15 days after Cal Dive receives written notification of the amount of the Stock Option Service Fee due for the month. Notwithstanding the foregoing, each calendar year Cal Dive may, in its discretion, elect to pay the aggregate Stock Option Service Fees for the calendar year in a single sum within 15 days after Cal Dive receives written notification of the amount of the aggregate Stock Option Service Fees for the calendar year.

          (b) Outstanding Helix Restricted Stock Awards. Notwithstanding the fact that under the terms of the Helix Stock Incentive Plans upon the Trigger Date the Transferred Employees shall be deemed to have terminated employment for all purposes of the Helix Stock Incentive Plans, Helix, in its sole discretion, may elect for any Transferred Employee that any or all restricted stock awards granted to such Transferred Employee under the Helix Stock Incentive Plans will continue under their present terms and the terms of the plans under which they were granted. For purposes of vesting of such restricted stock awards, employment with a Cal Dive Entity shall be treated in the same manner as if it were employment with Helix. In consideration of the foregoing agreements in this Section 4.2(b), following the Trigger Date, Cal Dive shall pay to Helix monthly service fees (“Restricted Stock Service Fees”). The Restricted Stock Service Fee for a month shall be an amount equal to the sum of (x) the aggregate third party costs incurred by Helix during the month in connection with the administration of the restricted stock awards granted to Transferred Employees under the Helix Stock Incentive Plans which Helix has elected to continue, as described above, and (y) the total costs and expenses recognized, accrued or otherwise incurred by Helix during the month for financial accounting purposes with respect to such restricted stock awards granted to Transferred Employees under the Helix Stock Incentive Plans and/or the agreements contained in the foregoing provisions of this Section 4.2(b) (the costs and expenses described in this clause (y) are referred to herein as the “Restricted Stock Accounting Costs and Expenses”). Helix’s determination concerning the amount of the Restricted Stock Accounting Costs and Expenses shall be binding on the parties hereto. The Restricted Stock Service Fees will be charged to Cal Dive on a monthly basis. Cal Dive shall pay to Helix the Restricted Stock Service Fee for a month within 15 days after Cal Dive receives written notification of the amount of the Restricted Stock Service Fee due for the month. Notwithstanding the foregoing, each calendar year Cal Dive may, in its discretion, elect to pay the aggregate Restricted Stock Service Fees for the calendar year in a single sum within 15 days after Cal Dive receives written notification of the amount of the aggregate Restricted Stock Service Fees for the calendar year.

     4.3 .Helix Employee Stock Purchase Plan. Transferred Employees who are participating in the Helix Energy Solutions Group, Inc. 1998 Employee Stock Purchase Plan (the “Helix Stock Purchase Plan”) on the date of the Agreement will continue to participate in the Helix Stock Purchase Plan through the end of the offering period in which the Transfer Date occurs. Cal Dive shall pay to Helix, within five days following the close of such offering period, the fair market value of the shares of Helix’s common stock purchased under the Helix Stock Purchase Plan during the offering period. For this purpose, the fair market value of a share of Helix common stock shall be the closing price of Helix stock on the New York Stock Exchange on the last trading day of the offering period in which the Transfer Date occurs.

     4.4 Annual Incentive Compensation. Cal Dive shall assume all liabilities with respect to the payment of annual incentive awards to Transferred Employees for the calendar year in which the Transfer Date occurs, subject to the terms and provisions of the applicable incentive plan.

     4.5 Workers’ Compensation. Except as otherwise specifically provided herein, Cal Dive shall be solely responsible for all claims for workers’ compensation reported by a Transferred Employee on or after the applicable Transfer Date. Unless Helix determines otherwise, Helix shall continue to be responsible after the Transfer Date for administering all claims for workers’ compensation for injuries to any Transferred Employee occurring prior to the applicable Transfer Date and reported timely under the terms of any Helix workers’ compensation policy or plan; provided, however, that Cal Dive shall reimburse, and shall indemnify Helix for any amounts payable under such prior programs, or for any claims not reported timely and where Helix has been prejudiced by such late reporting.

     4.6 Accrued Vacation and other Paid Time Off. Cal Dive and the Cal Dive Entities shall recognize and assume or retain, as the case may be, all liability for all vacation, holiday, flex days and sick days, including banked sick days accrued by Transferred Employees as of the applicable Transfer Date, on terms and conditions similar to those in effect immediately before such time.

     4.7 Leaves of Absence. Cal Dive shall honor the terms and conditions of any approved leave of absence of a Transferred Employee that begins before and continues immediately after the applicable Transfer Date.
