This Restricted Stock Unit Agreement (the “Agreement”) is dated as of by and between Axiall Corporation, a Delaware corporation (together with any Subsidiaries, as applicable, the “Company”), and (“Grantee” or “You”).

1. Grant of Restricted Stock Units. Subject to and upon the terms, conditions, and restrictions set forth in this Agreement and in the Company’s 2011 Equity and Performance Incentive Plan (the “Plan”), the Company has granted to Grantee, as of (the “Date of Grant”), restricted stock units (otherwise referred to in this Agreement as “Restricted Stock Units”). Each Restricted Stock Unit shall represent the contingent right to receive one share of Common Stock upon vesting of the Restricted Stock Unit.

2. Restrictions on Transfer of Restricted Stock Units. The Restricted Stock Units may not be transferred, sold, pledged, exchanged, assigned or otherwise encumbered or disposed of by Grantee. Any purported transfer, encumbrance or other disposition of the Restricted Stock Units that is in violation of this Agreement shall be null and void, and the other party to any such purported transaction shall not obtain any rights to or interest in the Restricted Stock Units.

3. Vesting of Restricted Stock Units. T he Restricted Stock Units specified in Section 1 of this Agreement shall vest as follows:

(a) On each of the first three (3) anniversaries of the Date of Grant, a number of Restricted Stock Units equal to thirty-three and one-third percent (33-1/3%) multiplied by the number of Restricted Stock Units specified in Section 1 of this Agreement shall become vested and nonforfeitable on a cumulative basis until 100% of the Restricted Stock Units specified in Section 1 of this Agreement have become vested and nonforfeitable. Each such anniversary date shall be a settlement date under this Agreement.

(b) In the event a Change in Control occurs prior to all of the Restricted Stock Units specified in Section 1 of this Agreement becoming vested and nonforfeitable as provided in Section 3(a) above and while Grantee is an employee of the Company or any Subsidiary, the Restricted Stock Units covered by this Agreement shall become vested and nonforfeitable if, in connection with such Change in Control, the successor corporation does not assume the obligations of the Company under this Agreement or provide Grantee with a substitute award with rights equivalent to the rights provided under this Agreement.

Subject to the following sentence, if the obligations of the Company under this Agreement remain unchanged or the successor corporation assumes the obligations of the Company under this Agreement or provides Grantee with a substitute award with rights equivalent to the rights provided under this Agreement, then no such acceleration shall apply and the terms of this Agreement shall apply to the assumed or substitute award, except as may otherwise be provided in a written agreement between Grantee and the Company.

Notwithstanding the foregoing, if, following a Change in Control, (i) the obligations of the Company under this Agreement remain unchanged or the successor corporation assumes the obligations of the Company under this Agreement or provides Grantee with a substitute award with rights equivalent to the rights provided under this Agreement and (ii) after the Change in Control, but prior to all of the Restricted Stock Units specified in Section 1 of this Agreement becoming vested and nonforfeitable, the Company or any successor corporation or any subsidiary of either terminates Grantee’s employment without Cause or Grantee terminates his employment for Good Reason, then the Restricted Stock Units

covered by this Agreement or any substitute award shall become vested and nonforfeitable upon such termination of employment.

4. Forfeiture of Restricted Stock Units. Except as provided in Section 3 or as the Committee may determine on a case-by-case basis, subject to the terms of the Plan, at such time as Grantee ceases to be continuously employed by the Company, any Restricted Stock Units that have not theretofore become vested and nonforfeitable hereunder shall be forfeited.

5. Payment of Restricted Stock Units. To the extent the Restricted Stock Units shall become vested and nonforfeitable pursuant to Section 3(a) above, shares of Common Stock underlying such Restricted Stock Units shall be transferred to Grantee no later than earlier of: (a) 15 days after the date on which the Restricted Stock Units become vested and nonforfeitable (i.e., the respective settlement date) and (b) December 31 st of the calendar year that includes the third anniversary of the Date of Grant , except as otherwise provided in Section 7. To the extent the Restricted Stock Units become vested and nonforfeitable pursuant to Section 3(b) above or upon termination of employment following the Change in Control, then even though such Restricted Stock Units become vested and nonforfeitable upon the occurrence of the Change in Control or termination of employment after the Change in Control, payment will not be made to Grantee until the date or dates payment otherwise would have been made in the absence of such Change in Control or termination of employment after the Change in Control had Grantee continued to be employed by the Company. In such case, shares of Common Stock underlying such Restricted Stock Units shall be issued to Grantee no later than the earlier of (a) 15 days after the respective settlement date or dates and (b) December 31 st of the calendar year that includes the third anniversary of the Date of Grant, except as otherwise provided in Section 7.

6. Dividend, Voting and Other Rights. The Restricted Stock Units shall not be considered to be shares of Common Stock or other securities of the Company. Grantee shall have no rights of ownership in the shares of Common Stock underlying the Restricted Stock Units, including,, for greater certainty, the right to vote suchshares, until such shares of Common Stock are issued to Grantee pursuant hereto. Dividend equivalents will be paid in cash on the shares of Common Stock underlying the Restricted Stock Units upon the vesting of the related Restricted Stock Units and paid at the same time the underlying shares are issued to Grantee.

7. Issuance of Restricted Stock Units by the Company. The shares of Common Stock underlying the Restricted Stock Units shall be issued to Grantee by the Company’s transfer agent at the direction of the Company. At such time as the Restricted Stock Units become payable as specified in this Agreement, the Company shall direct the transfer agent to issue and forward all such payable shares of Common Stock to Grantee except, in the event that Grantee has notified the Company of his election pursuant to Section 14 to satisfy any tax obligations by having the Company withhold from the shares required to be delivered to Grantee such number of shares of Common Stock having a value equal to the amount required to be withheld, the transfer agent will be directed to issue the remaining balance of shares after the amount necessary for such taxes has been deducted.

8. Restrictive Covenants

(i) Grantee shall hold in a fiduciary capacity for the benefit of the Company all Confidential Information, including but not limited to trade secrets (as “trade secrets” are defined by applicable Georgia law) pursuant to this Agreement and as otherwise required by law. During Grantee’s employment with the Company and following the termination of Grantee’s employment for any reason, Grantee shall not, without the prior written consent of the Company or as may otherwise be

The protection afforded to Confidential Information by this Agreement is not intended by the parties hereto to limit, and is intended to be in addition to, any protection provided to any such information under any applicable federal, state, or local law.

(ii) All files, records, documents, drawings, specifications, data, computer programs, customer or vendor lists, specific customer or vendor information, marketing techniques, business strategies, contract terms, pricing terms, discounts and management compensation of the Company whether prepared by Grantee or otherwise coming into Grantee’s possession, shall remain the exclusive property of the Company and Grantee shall not remove any such items from the premises of the Company, except in furtherance of Grantee’s duties.

At the Company’s request and expense, Grantee will reasonably assist the Company during the period of Grantee’s employment by the Company and thereafter in connection with any controversy or legal proceeding relating to a Grantee Invention and in obtaining domestic and foreign patent or other protection covering a Grantee Invention. As a matter of record, Grantee hereby states that he or she has provided below a list of all unpatented inventions in which Grantee owns all or partial interest..

enterprise which engages or proposes to engage in the Business within the Restricted Territory. Notwithstanding the foregoing, nothing in this Agreement shall prevent Grantee from owning for passive investment purposes not intended to circumvent this Agreement, less than five percent (5%) of the publicly traded voting securities of any company engaged in the Business (so long as Grantee has no power to manage, operate, advise, consult with or control the competing enterprise and no power, alone or in conjunction with other affiliated parties, to select a director, manager, general partner, or similar governing official of the competing enterprise other than in connection with the normal and customary voting powers afforded Grantee in connection with any permissible equity ownership).

(d) Remedies: Specific Performance. The parties acknowledge and agree that Grantee’s breach or threatened breach of any of the restrictions set forth in this Section will result in irreparable and continuing damage to the Company for which there may be no adequate remedy at law and that the Company shall be entitled to equitable relief, including specific performance and injunctive relief as remedies for any such breach or threatened or attempted breach. Grantee hereby consents to the grant of an injunction (temporary or otherwise) against Grantee or the entry of any other court order against Grantee prohibiting and enjoining him from violating, or directing him to comply with any provision of this Section. Grantee also agrees that such remedies shall be in addition to any and all remedies, including damages, available to the Company against him for such breaches or threatened or attempted breaches. In addition, without limiting the remedies of the Company for any breach of any restriction on Grantee set forth in this Section, except as required by law, Grantee shall forfeit any and all Restricted Stock Units set forth in Section 1 hereof if Grantee breaches the covenant applicable to Grantee contained in this Section and the Company will have no obligation to grant or vest any additional Restricted Stock Units.

(e) Communication of Contents of Agreement. During Grantee’s employment and for one year thereafter, Grantee will communicate his obligations under this Section to any person, firm, association, partnership, corporation or other entity which Grantee intends to be employed by, associated with, or represent.

(f) Independent Covenants. The existence of any claim, demand, action or cause of action of Grantee against the Company, whether predicated upon this Agreement or otherwise, is not to constitute a defense to the Company’s enforcement of any of the covenants or agreements contained in this Section. The Company’s rights under this Agreement are in addition to, and not in lieu of, all other rights the Company may have at law or in equity to protect its confidential information, trade secrets and other proprietary interests.

(g) Extension. If a court of competition jurisdiction finally determines that Grantee has violated any of Grantee’s obligations under this Section, then the period applicable to those obligations is to automatically be extended by a period of time equal in length to the period during which those violations occurred.

the extent not prohibited by applicable law, and agrees not to assert by way of motion, as a defense or otherwise, in any such action, any claim that it is not subject personally to the jurisdiction of the above named courts, that any such proceeding brought in one of the above named courts is improper, or that this Agreement or the subject matter hereof or thereof may not be enforced in or by such court and (iii) hereby agrees not to commence or maintain any action, claim, cause of action, or suit (in contract, tort, or otherwise), inquiry, proceeding, or investigation arising out of or based upon this Agreement or relating to the subject matter hereof or thereof other than before one of the above named courts nor to make any motion or take any other action seeking or intending to cause the transfer or removal of any such action, claim, cause of action, or suit (in contract, tort, or otherwise), inquiry, proceeding or investigation to any court other than one of the above named courts whether on the grounds of inconvenient forum or otherwise.
