 TAX SHARING AND INDEMNIFICATION AGREEMENT 
  
 THIS IS A
TAX SHARING AND INDEMNIFICATION AGREEMENT (the “Agreement”), dated as of the Effective Date, made by and among Crown, Cork & Seal Company Inc., a Pennsylvania corporation (“Crown”) on behalf of itself and each member of the
Crown Group, Constar International Inc., a Delaware corporation (“Constar”), on behalf of itself and each member of the Constar Group, and their respective successors. 
  
 Background 
  
  A.    Crown plans to sell approximately 55% of its Constar stock to the public in a public offering (the “Offering”). As a result of the Offering, Constar and members of the Constar Group will no longer
be members of the Crown Group for the purpose of filing consolidated federal income Tax Returns. Pursuant to this Agreement, Members of the Constar Group will no longer file consolidated, combined or unitary income Tax Returns (or participate in
group relief or any similar arrangement) with any members of the Crown Group for foreign Tax purposes and for state Tax purposes unless otherwise required by law; 
   
 B.    The Parties are entering into this Agreement: to provide for the Parties’ respective liabilities for Taxes; to provide certain indemnities;
and to provide for various administrative matters relating to Taxes including: (1) the preparation and filing of Tax Returns along with the payment of Taxes due and payable, (2) the retention and maintenance of relevant records necessary to prepare
and file appropriate Tax Returns, as well as the provision for appropriate access to those records by the Parties to this Agreement, (3) the conduct of audits, examinations, and proceedings by appropriate governmental entities that could result in a
redetermination of Taxes, and (4) the cooperation of all Parties with one another in order to fulfill their duties and responsibilities under this Agreement and under the Code and other applicable law; and 
  
 C.    It is the intent of the Parties that Crown shall economically bear the burden of all Taxes that are due under
any consolidated, combined or unitary Tax Return (or group relief or similar arrangement) that includes any member or members of the Constar Group and at least one member of the Crown Group that is not a member of the Constar Group for periods up to
and ending with the completion of the Offering (a “Crown Consolidated Return”) and that Constar or the appropriate member of the Constar Group shall economically bear the burden of all Taxes otherwise imposed upon or attributable to the
members of the Constar Group.

 ARTICLE III

 PAYMENT OF TAXES UPON FILING AND UPON SUBSEQUENT ADJUSTMENT 
  
 Section 3.1.  Taxes Generally.    Except as provided in Section 3.2 of this Agreement, Crown shall pay or cause to be paid and shall indemnify and hold Constar and
the members of the Constar Group harmless against all Tax Liabilities that arise under each Crown Consolidated Return. Constar shall pay or cause to be paid and shall indemnify and hold Crown and the members of the Crown Group harmless against all
Tax Liabilities that arise under each Constar Return. Crown and Constar shall share all Tax Liabilities arising under Combined State Tax Returns in accordance with Section 3.3 hereof. 
  
 Section 3.2.  Straddle Periods.    If, for purposes of a Crown Consolidated Return, a taxable period of any member of the Constar Group
includes the Effective Date but does not end on the Effective Date (as otherwise generally provided under Section 2.3 of this Agreement) (a “Straddle Period”), Crown shall pay or cause to be paid and shall indemnify and hold Constar and
the members of the Constar Group harmless against the Tax Liabilities attributable to the affected member or members of the Constar Group for the portion of such tax period ending on the Effective Date and Constar shall pay or cause to be paid and
shall indemnify and hold Crown and the members of the Crown Group harmless against the Tax Liabilities attributable to the affected member or members of the Constar Group for the remainder of such tax period beginning with the day after the
Effective Date. Tax Returns for such Straddle Periods shall be referred to as “Straddle Period Returns.” The determination of 
 

 5 








 
Tax Liabilities up to and following the Effective Date shall be based upon an interim closing of the books of the affected member or members of the Constar Group as of the opening of the day
following the Effective Date and shall otherwise follow the principles of Section 3.3. Crown shall determine the amounts owed by Constar under this Section 3.2 and provide to Constar a statement showing the amount owed by Constar within 20 days of
the due date of any Straddle Period Return (determined without regard to applicable extensions). Constar shall pay to Crown its portion of Taxes determined under this Section 3.2 for Straddle Period Returns to Crown no less than 10 days prior to the
due date of any Straddle Period Return (determined without regard to applicable extensions). Interest shall accrue at a rate of 8% on any payment required by this Section 3.2 not made within the time specified in the immediately preceding sentence.
Crown shall refund to Constar the excess of any payment made by Constar over the amount calculated following the principles of this Section 3.2 applied to the tax shown due and payable on any Straddle Period Return as filed. Crown shall prepare a
second statement showing any additional amount owed by Constar or any amount payable by Crown to Constar 30 days after the filing of any Combined State Tax Return. Constar shall pay to Crown any amount owed under this Section 3.3 no less than 5 days
after receiving an Interim Statement or Final Statement. Crown shall pay any amount owed to Constar under this Section 3.2 no less than 5 days after Crown delivers the Final Statement. Interest shall accrue at a rate of 8% on any payment required by
this Section 3.2 not made within the time specified in the two preceding sentences. 
  
  Section
3.3.  Tax Liability under Combined State Tax Returns.    Crown shall pay or cause to be paid and shall indemnify and hold Constar and the members of the Constar Group harmless against, all Tax Liabilities due and
payable with respect to each Combined State Tax Return to the extent such Tax Liabilities are attributable to any member of the Crown Group. Constar shall pay or cause to be paid to Crown and shall indemnify and hold Crown and the members of the
Crown Group harmless against all Tax Liabilities due and payable with respect to each Combined State Tax Return to the extent such Tax Liabilities are attributable to any member of the Constar Group. For purposes of this Section 3.3, the portion of
Tax Liabilities attributable to a member shall be determined by allocating the Tax due and payable with respect to a Combined State Tax Return among the members in the same proportion that each such member’s taxable income, determined on a
separate company basis, bears to the sum of the separate taxable incomes of all members having separate taxable income (and disregarding losses of any member). The excess of the Tax Liability of a member determined on a separate company basis over
the allocable portion of the Tax Liability of such member as determined under the immediately preceding sentence shall be paid by such member to the other member or members having losses in direct proportion to the reduction in Tax Liability
resulting from the inclusion of such loss member or members. In no event shall this Section 3.3 require a member of either the Constar Group or Crown Group to make a payment to another member in the same group. Crown shall determine the amounts owed
under this Section 3.3 and provide to Constar, on a quarterly basis, a statement showing the amount owned by Constar (an “Interim Statement”). Crown shall prepare a final statement showing any additional amount owed by Constar or any
amount payable by Crown to Constar 30 days after the filing of any Combined State Tax Return (a “Final Statement”). Constar shall pay to Crown any amount owed under this Section 3.3 no less than 5 days after receiving an Interim Statement
or Final Statement. Crown 
  

 6 








 
shall pay any amount owed to Constar under this Section 3.3 no less than 5 days after Crown delivers the Final Statement. Interest shall accrue at a rate of 8% on any payment required by this
Section 3.3 not made within the time specified in the two preceding sentences. 
  
  Section
3.4.  Adjustments.    If any Tax Return is examined by a taxing authority and an Adjustment results from such examination, the Party bearing responsibility for such Taxes determined under this Article III shall pay
its share of any additional Tax Liability resulting from the Adjustment, determined in accordance with the principles set forth in Section 3.3, within 30 days following a Final Determination of such Adjustment and any refund, credit or similar
reduction in Tax Liability arising from such Adjustment shall be apportioned among the Parties in accordance with the principles set forth in Section 3.3, provided, however, that if the Adjustment results in an increase in the Tax Liability
of one Party and a Tax Benefit to the other Party, the Party receiving such Tax Benefit, to the extent it is equal to or less than the other Party’s additional Tax Liability, shall pay the amount of such Tax Benefit to such other Party within
30 days after such Tax Benefit is realized. Promptly after receiving notice from the Party having the Adjustment that results in additional Tax Liability, the other Party shall make a claim for any Tax Benefit resulting from such Adjustment, on an
amended Tax Return or in a formal or informal claim filed with the IRS or other taxing authority, unless the amount of such Tax Benefit is immaterial or unless otherwise agreed by the Parties. 
   
 Section 3.5.  Refunds.    If one Party receives a refund in respect of amounts paid by the other
Party to any taxing authority on its behalf, or should any such amounts that would otherwise be refundable to one Party be applied by the taxing authority to obligations of the other Party as determined under this Agreement, then the Party in
receipt of such refund or notification of credit, shall promptly following receipt (or notification of credit), remit such refund (or the amount of such credit) and any related interest to the other Party. 
  
  
 ARTICLE IV 
 COOPERATION AND EXCHANGE OF INFORMATION; AUDITS AND ADJUSTMENTS 
  
 Section
4.1.  Waiver of Carrybacks.    If any member of the Constar Group generates a net operating loss in a taxable period beginning after the Effective Date, Constar hereby agrees to waive (or cause such other member of
the Constar Group to waive) the right to carry back such net operating loss pursuant to Code Section 172(b)(3), so that no such net operating losses will be carried back to any Crown Consolidated Return. Similar procedures shall be followed in any
state or locality where Constar might otherwise have the right to carry back a net operating loss to a Crown Group combined, consolidated or unitary Tax Return. In no circumstances shall Constar have the right to carry back a net operating loss to a
Crown Consolidated Return, and any refund or credit that may be paid to or received by the Crown Group on account of any such carryback shall remain the sole property of the Crown Group. 
  
 Section 4.2.  Tax Return Information. 
  
 (a)  Constar shall, and shall cause each appropriate member of the Constar Group to, provide Crown with all information and other assistance reasonably requested by 
 

 7 








 
Crown to enable Crown to prepare and file Crown Consolidated Returns and Combined State Tax Returns. 
  
  (b)  Crown shall, and shall cause each appropriate member of the Crown Group to, provide Constar with all information and other assistance
reasonably requested by Constar to enable Constar to prepare and file Constar Returns. 
   
 (c)  After filing of the final Crown Consolidated Returns, Crown will inform Constar of the amount of consolidated carryovers which are attributed to Constar and each member of the Constar Group as provided by Treasury
Regulation Section 1.1502-21 or any other similar law or regulation. 
  
 Section 4.3.  Audits and
Adjustments. 
  
 (a)  If Crown or Constar receives in writing from the IRS or any other
taxing authority notice of an Adjustment that may give rise to a payment from the other Party under this Agreement or otherwise affect the other Party’s Taxes, Crown or Constar, as the case may be, shall give written notice of the Adjustment to
the other Party within 30 days of becoming aware of the Adjustment but in no case later than 10 days before Crown or Constar, as the case may be, is required to respond to the IRS or other taxing authority, provided that failure to give such timely
notice shall not relieve the Party entitled to such notification of its obligations hereunder except to the extent actually prejudiced thereby. The Party primarily liable for any Tax Liability with respect to the Adjustment under Article III (the
“Primary Party”) at its own expense shall have control over all matters relating to the Adjustment that may give rise to a payment obligation by the Primary Party, provided, however, that the other Party (the “Non-Primary
Party”) may settle, partially settle, or otherwise resolve any controversy involving the Non-Primary Party’s Taxes to which the particular Adjustment relates, so long as the Non-Primary Party does not settle, partially settle, or otherwise
resolve the controversy in a manner inconsistent with the Primary Party’s position, without the prior written consent of the Primary Party, which consent shall not be unreasonably withheld. 
  

(b)  Constar agrees reasonably to cooperate with Crown in the negotiation, settlement, or litigation of any liability for Taxes of any member
of the Crown Group. 
  
 (c)  Crown agrees reasonably to cooperate with Constar in the
negotiation, settlement, or litigation of any liability for Taxes of any member of the Constar Group. 
  
 (d)  Crown will promptly notify Constar in writing of any Adjustment involving a change in the tax basis of any asset of Constar or any change in any Tax attribute of Constar, specifying the nature of the change so that the
Constar Group will be able to reflect the revised basis or attribute in its tax books and records for periods beginning on or after the Effective Date.

 ARTICLE V 
 RETENTION OF RECORDS;
STATUTE OF LIMITATIONS 
  
  Section 5.1.  Retention of Records.    Crown
and Constar agree to retain the appropriate records which may affect the determination of the liability for Taxes of any member of the Crown Group or the Constar Group, respectively, until such time as there has been a Final Determination with
respect to such liability for Taxes. A Party may satisfy its obligations under the preceding sentence by allowing the other Party to duplicate records at such other Party’s request and expense. 
   
 Section 5.2.  Statute of Limitations.    Crown and Constar will notify each other in writing of any
waivers or extensions of the applicable statute of limitations that may affect the period for which any materials, records, or documents must be retained. 
  
  

ARTICLE VI 
 RESOLUTION OF DISPUTES 
  
 Section 6.1.  Disputes. 
  
 (a)  Resolution of any and all disputes arising from or in connection with this Agreement, whether based on contract, tort, statute or otherwise,
including, but not limited to, disputes in connection with claims by third Parties (collectively, “Disputes”), shall be subject to the provisions of this Section 6.1; provided, however, that nothing contained herein shall preclude either
Party from seeking or obtaining (i) injunctive relief or (ii) equitable or other judicial relief to enforce the provisions hereof or to preserve the status quo pending resolution of Disputes hereunder. 
  
 (b)  Either Party may give the other Party written notice of any Dispute not resolved in the normal course of
business. The Parties shall attempt in good faith to resolve any Dispute promptly by negotiation between executives of the Parties who have authority to settle the controversy and who are at a higher level of management than the persons with direct
responsibility for administration of this Agreement. Within 30 days after delivery of the notice, the foregoing executives of both Parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary
for a period not to exceed 15 days, to attempt to resolve the Dispute. All reasonable requests for information made by one Party to the other will be honored. If the Parties do not resolve the Dispute within such 45 day period (the “Initial
Negotiation Period”), the Parties shall attempt in good faith to resolve the Dispute by negotiation between (a) in the case of Crown, the Chief Executive Officer, and (b) in the case of Constar, the Chief Executive Officer (collectively, the
“Designated Officers”). Such officers shall meet at a mutually acceptable time and place (but in any event no later than 15 days following the expiration of the Initial Negotiation Period) and thereafter as often as they reasonably deem
necessary for a period not to exceed 15 days, to attempt to resolve the Dispute. 
  
 (c)  If the Dispute has not been resolved by negotiation within 75 days of the first Party’s notice, or if the Parties failed to meet within 30 days of the first Party’s notice, or if 
 

 9 








 
the Designated Officers failed to meet within 60 days of the first Party’s notice, either Party may commence any litigation or other procedure allowed by law.
