(a) Subject to Section 5.3, Constar shall indemnify and hold harmless each Crown Entity and its Affiliates and each of their respective directors, officers, employees, agents, consultants, advisors, accountants, attorneys and representatives (each, a “Crown Indemnitee”) from and against any and all Liabilities incurred or suffered by any Crown Indemnitee arising out of (i) any and all Constar Entity Liabilities, (ii) the breach by any Constar Entity of any obligation under this Agreement, and (iii) any claim by any Constar Subsidiary or Constar Equity-Interest Entity that any Crown Indemnitee breached any fiduciary duty (or similar concept) as a stockholder, officer or director of such entity or otherwise by reason of the fact that any Crown Indemnitee pursued or acquired a Corporate Opportunity for any Crown Entity, directed, sold, assigned or otherwise transferred or dealt in such Corporate Opportunity to another Person, or did not communicate information regarding such Corporate Opportunity to such entity.

(b) Subject to Section 5.3, Constar shall indemnify and hold harmless each Crown Indemnitee from and against any and all Liabilities caused by any untrue statement or alleged untrue statement of a material fact contained in any document filed with the SEC by any Crown Entity pursuant to the Securities Act or the Exchange Act, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that those Liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information that any Constar Entity furnishes in writing or fails to furnish to any Crown Indemnitee for inclusion in any document filed by any Crown Entity with the SEC, if that statement or omission was made or occurred after the Initial Public Offering Date.

(c) Subject to Section 5.3, Constar shall indemnify and hold harmless each Crown Indemnitee from and against any and all Liabilities caused by any untrue statement or alleged untrue statement of a material fact contained in Constar’s registration statement on Form S-1 (Reg. No. 333-88878), as amended from time to time (the “Registration Statement”) or in any prospectus related thereto filed under Rule 424 of the Securities Act (the “Final Prospectus”), or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

5.2. Crown Indemnification of Constar Entities. Subject to Section 5.3, Crown shall indemnify and hold harmless each Constar Entity and its Affiliates and each of their respective directors, officers, employees, agents, consultants, advisors, accountants, attorneys and representatives (each, a “Constar Indemnitee”) from and against any and all Liabilities incurred or suffered by any Constar Indemnitee arising out of (i) any and all Crown Entity Liabilities and (ii) the breach by any Crown Entity of any obligation under this Agreement; provided, however, that Crown shall not have any obligation to indemnify or hold harmless any Constar Indemnitee, and Crown shall have no Liability to any Constar Indemnitee, with respect to any Liabilities caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Final Prospectus, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

5.3. Limitations.

(a) Any indemnification pursuant to Section 5.1 or Section 5.2 shall be paid net of any tax benefit to the Indemnified Party attributable to the relevant payment. It is expressly agreed that no insurer or any other third party shall be (i) entitled to a benefit (as a third-party beneficiary or otherwise) that it would not be entitled to receive in the absence of Section 5.1 or Section 5.2, (ii) relieved of the responsibility to pay any claims to which it is obligated or (iii) entitled to any subrogation rights with respect to any obligation under Section 5.1 or Section 5.2.

(b) To the extent that the Ancillary Agreements contain provisions that limit the liability of the parties thereto, contain indemnification provisions, or otherwise conflict with Section 5.1 or Section 5.2 above, the terms of the Ancillary Agreements shall govern.

(c) Notwithstanding Section 5.1 and Section 5.2 or the other provisions hereof, neither party shall be liable for any special, indirect, incidental or consequential damages relating to claims of the other party.

(d) The amount that any Indemnifying Party is or may be required to pay any Indemnified Party hereunder shall be reduced (retroactively or prospectively) by any insurance proceeds, settlement recoveries or other amounts actually recovered by or on behalf of such Indemnified Party in respect of any indemnification pursuant to Section 5.1 or 5.2, as the case may be (an “Actual Recovery”). If an Indemnified Party shall have received the payment required by this Agreement from an Indemnifying Party in respect of any indemnification pursuant to Section 5.1 or 5.2, as the case may be, and shall subsequently receive an Actual Recovery, then such Indemnified Party shall pay to such Indemnifying Party a sum equal to the amount of such Actual Recovery up to the aggregate payments made by such Indemnifying Party pursuant to this Agreement in respect of such indemnification pursuant to Section 5.1 or 5.2, as the case may be.

5.4. Notice and Payment of Claims. If any Crown Indemnitee or Constar Indemnitee (the “Indemnified Party”) determines that it is or may be entitled to indemnification by any party

(the “Indemnifying Party”) under Article IV of this Agreement (other than in connection with any Action subject to Section 5.5), the Indemnified Party shall deliver to the Indemnifying Party a written notice specifying, to the extent reasonably practicable, the basis for its claim for indemnification and the amount for which the Indemnified Party reasonably believes it is entitled to be indemnified. Within 30 days after receipt of that notice, the Indemnifying Party shall pay the Indemnified Party that amount in cash or other immediately available funds unless the Indemnifying Party objects to the claim for indemnification or the amount of the claim. If the Indemnifying Party does not give the Indemnified Party written notice objecting to that indemnity claim and setting forth the grounds for the objection(s) within that 30-day period, the Indemnifying Party shall be deemed to have acknowledged its liability for that claim and the Indemnified Party may exercise any and all of its rights under applicable law to collect that amount. If there is a timely objection by the Indemnifying Party, the Indemnifying Party shall pay to the Indemnified Party in cash the amount, if any, that is Finally Determined to be required to be paid by the Indemnifying Party in respect of that indemnity claim within 15 days after that indemnity claim has been so Finally Determined.

5.5. Notice and Defense of Third-Party Claims. Promptly after the earlier of receipt of (i) notice that a third party has commenced an Action against or otherwise involving any Indemnified Party or (ii) information from a third party alleging the existence of a claim against an Indemnified Party, in either case, with respect to which indemnification may be sought under Article IV of this Agreement (a “Third-Party Claim”), the Indemnified Party shall give the Indemnifying Party written notice of the Third-Party Claim. The failure of the Indemnified Party to give notice as provided in this Section 5.5 shall not relieve the Indemnifying Party of its obligations under this Agreement, except to the extent that the Indemnifying Party is prejudiced by the failure to give notice. Within 30 days after receipt of that notice, the Indemnifying Party may (i) at its option, elect to assume and control the defense of that Third-Party Claim at its sole cost and expense by giving written notice to that effect to the Indemnified Party, or (ii) object to the claim for indemnification set forth in the notice delivered by the Indemnified Party pursuant to the first sentence of this Section 5.5; provided, that if the Indemnifying Party does not within that 30-day period give the Indemnified Party written notice objecting to that indemnification claim and setting forth the grounds for the objection(s), the Indemnifying Party shall be deemed to have acknowledged its liability for that indemnification claim. If the Indemnifying Party has acknowledged its obligation to indemnify the Indemnified Party and elected to assume the defense of a Third-Party Claim, (x) the defense shall be conducted by counsel retained by the Indemnifying Party and reasonably satisfactory to the Indemnified Party; provided, that the Indemnified Party shall have the right to participate in those proceedings and to be represented by counsel of its own choosing at the Indemnified Party’s sole cost and expense; and (y) the Indemnifying Party may settle or compromise the Third-Party Claim without the prior written consent of the Indemnified Party so long as any settlement or compromise of the Third-Party Claim includes an unconditional release of the Indemnified Party from all claims that are the subject of that Third-Party Claim; provided, that the Indemnifying Party may not agree to any such settlement or compromise pursuant to which any remedy or relief, other than monetary damages for which the Indemnifying Party shall be responsible under this Agreement, shall be applied to or against the Indemnified Party, without the prior written consent of the Indemnified

Party, which consent shall not be unreasonably withheld. If the Indemnifying Party does not assume the defense of a Third-Party Claim for which it has acknowledged its obligation to indemnify the Indemnified Party, the Indemnified Party will act in good faith with respect to that Third-Party Claim and may require the Indemnifying Party to reimburse it on a current basis for its reasonable expenses of investigation, reasonable attorney’s fees and reasonable out-of-pocket expenses incurred in investigating and defending against that Third-Party Claim and the Indemnifying Party shall be bound by the result obtained with respect to that claim by the Indemnified Party; provided, that the Indemnifying Party shall not be liable for any settlement or compromise of any Third-Party Claim effected without its consent, which consent shall not be unreasonably withheld. The Indemnifying Party shall pay to the Indemnified Party in cash the amount, if any, for which the Indemnified Party is entitled to be indemnified under this Agreement within 15 days after that Third-Party Claim has been Finally Determined.

5.6. Contribution.

If for any reason the indemnification provided for in Sections 5.1 or 5.2 is unavailable to any Indemnified Party, or insufficient to hold it harmless, then the Indemnifying Party shall contribute to the amount paid or payable by that Indemnified Party as a result of those Liabilities in that proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other hand, in connection with those statements or omissions, which relative fault shall be determined by reference to the Crown Entity or Constar Entity to which those actions, conduct, statements or omissions are primarily related, as well as any other relevant equitable considerations.

ARTICLE VI

TERM

6.1. Effectiveness. The terms of this Agreement shall not become effective until the Initial Public Offering Date.

6.2. Termination of the Agreement. This Agreement shall remain in effect indefinitely.

ARTICLE VII

INSURANCE

7.1. Deductibles. To the extent that a claim is made in respect of any Constar Entity Liability, such Constar Entity Liability is covered by an insurance policy held by Crown, and the insurer makes payment under such policy in respect of such claim, then any deductible associated with such payment shall be paid by Constar.

7.2 Director and Officer Insurance. From and after the Initial Public Offering Date, Crown shall timely notify Constar of any amendments or modifications to and limitations on availability of the director and officer insurance policies of Crown that apply to directors and officers of Constar as of October 14, 2002 for the period ending on such date. Crown and Constar hereby acknowledge and agree that the service of any person (other than a person who is also a director or officer of Crown after the Initial Public Offering Date) as an officer or director of any Constar Entity after October 14, 2002 shall be at the mutual request of such person, Constar and any such Constar Entity and not at the request of any other individual, entity or group.

ARTICLE VIII

OPTION

8.1. Option.

(a) Eligible Offering. Except as otherwise provided in subsection (d) of this Section 8.1, Crown shall have the continuing right (the “Option”) to purchase a percentage (the “Option Percentage”) of any future offering (an “Eligible Offering”) of (1) equity securities of Constar, (2) debt or other securities of Constar convertible into or exchangeable for or carrying rights or options to purchase equity securities of Constar or (3) any other voting securities of Constar, such Option Percentage to be equal to the Crown Ownership Percentage, calculated as of the date of delivery of the Notice of Eligible Offering (as defined in Section 8.1(b)).

(b) Notice of Eligible Offering. Before issuing any securities pursuant to an Eligible Offering, Constar shall give written notice thereof to Crown (the “Notice of Eligible Offering”). The Notice of Eligible Offering must specify the type and number of securities Constar proposes to issue, the consideration that it intends to receive for such securities being issued and the other terms of the Eligible Offering. For a period of twenty (20) days following the delivery of the Notice of Eligible Offering, Crown will be entitled, by written notice to Constar, to elect to purchase all or a portion of the Option Percentage of the securities being sold in the Eligible Offering; provided, however, that it shall be a condition to Crown’s obligation to complete such purchase that Constar has completed the sale of the remainder of the securities to be sold in the Eligible Offering. At the closing of such sale, Constar shall sell to Crown, and Crown shall purchase from Constar, for the consideration and on the terms set forth in the Notice of Eligible Offering, the number of securities that Crown shall have elected to purchase.

(c) Sale to Third Parties. If Crown does not exercise its Option with respect to any securities included in an Eligible Offering within the required twenty (20) day period, then Constar may sell such securities to third parties, but only upon the terms set forth in the Notice of Eligible Offering and only within a period of one hundred twenty (120) days after delivery therof to Crown. After the expiration of such 120-day period, no Eligible Offering may be made or consummated unless Constar resubmits a Notice of Eligible Offering and complies with this Section 8.1.

(d) Exceptions to Issuances of Equity Securities. Notwithstanding any other provision in this Agreement to the contrary, Crown shall not have any preemptive right to purchase equity securities issued in connection with, and up to the amounts authorized by, the employee compensation plans described in the Registration Statement.

(e) Effect of Failure to Exercise. Except as provided in Section 8.1, any failure by Crown to exercise the Option, or any exercise for less than all shares purchasable under the Option, in connection with any particular Eligible Offering shall not affect Crown’s right to exercise the Option in connection with any subsequent Eligible Offering.
