Capitalized terms used in this Agreement but not otherwise defined shall have the respective meanings ascribed to such terms in the Stock Purchase Agreement, dated as of May 19, 2010 (the “Stock Purchase Agreement”), by and among Buyer and the Frost Group Shareholders.

Acquired Securities placed in escrow are referred to as “Escrow Securities” and will be released from escrow against payment (including partial payment) of the Notes as set forth herein.

WHEREAS, Escrow Agent has agreed to accept, hold, administer and disburse the securities and funds deposited with it and the earnings thereon in accordance with the terms of this Agreement.

NOW THEREFORE, in consideration of the foregoing and of the mutual covenants hereinafter set forth, the parties hereto agree as follows:

Section 1. Definitions

The following terms shall have the following meanings when used in this Agreement:

“Business Day” shall mean any day other than a Saturday, Sunday or any other day on which the Escrow Agent located at the notice address set forth in Section 11 is authorized or required by law or executive order to remain closed.

“Escrow Securities” means common shares and warrants for common shares of WPI deposited with Escrow Agent (initially being 17,085,011 and 8,319,035, respectively) (the “Escrow Deposit”), together with Escrow Income.

“Escrow Income” means any interest, dividends or income or proceeds that may accrue on the Escrow Deposit and the Escrow Funds.

“Escrow Funds” means amounts payable under the Notes.

“Joint Written Direction” means a written direction executed by Representative and an authorized officer of Buyer directing Escrow Agent to take or refrain from taking any action pursuant to this Agreement.

Section 2. Establishment of Escrow Accounts

(a) The Frost Group Shareholders and Buyer hereby appoint Escrow Agent to serve as escrow agent hereunder. Escrow Agent hereby accepts such appointment and, upon receipt of the Escrow Deposit, agrees to hold, invest and disburse the Escrow Securities in accordance with this Agreement.

(b) On the date of this Agreement, each of the Frost Group Shareholders will, in satisfaction of its obligations to the Buyer under the Stock Purchase Agreement, transfer the Escrow Deposit to Escrow Agent by depositing with Escrow Agent certificates for all of the Escrow Securities, with stock powers assigning the Escrow Securities to Buyer.

(c) Escrow Agent shall establish a special escrow account, shall keep such account separate and apart from all other funds and assets held by it, and shall hold the Escrow Securities in escrow and administer the Escrow Securities pursuant to the terms and conditions of this Agreement.

(d) The Escrow Funds shall be deposited by Buyer with Escrow Agent and held in the separate account.

(e) The Escrow Securities and Escrow Funds are referred to herein as the “Escrow”.

(f) Except to the extent that and until Representative (on behalf of the Frost Group Shareholders) or Buyer is or becomes expressly entitled to a distribution of all or a portion of the Escrow pursuant to the terms of this Agreement, the Frost Group Shareholders and Buyer intend, and hereby inform Escrow Agent, that the Escrow shall constitute an escrow account in which neither the Frost Group Shareholders nor Buyer nor their respective creditors have any legal or equitable right, title or interest of any kind whatsoever, except for such rights, title and interests as are expressly conveyed by the terms and conditions of this Agreement.

Section 3. Claims Against the Escrow, Voting and Sale of Escrow Securities

(a) It is agreed that Representative and Buyer shall authorize the Escrow Agent to release all of the Escrow Securities with stock powers to Buyer upon payment of the entire principal balance and all accrued interest under the Notes.

(b) It is agreed that Representative and Buyer shall authorize the Escrow Agent from time to time to release a pro rata portion of the Escrow Securities to Buyer upon payment of a portion, but less than all, of the principal balance of the Notes (together with all accrued interest). The amount of Escrow Securities to be released upon any partial payment shall be calculated by Representative and Buyer as follows: (i) amount of partial principal payment, divided by (ii) the original principal amount, multiplied by (iii) the number of Escrow Securities originally deposited. The Escrow Securities released will be divided between common shares and warrants in the proportion the same where originally deposited into Escrow. All payments under the Notes shall be deposited into Escrow and will be released to the Representative following release to Buyer of the requisite amount of Escrow Securities.

(c) It is agreed that in the event that there is an Event of Default under the Notes (as defined in the Notes), Representative and Buyer shall authorize the Escrow Agent to convey the then remaining Escrow Securities to Representative; said conveyance shall be considered to be in full satisfaction of the outstanding balance of the Notes.

(d) It is agreed that Representative and Buyer shall authorize the Escrow Agent to release all or any portion of the Escrow Securities that Buyer desires be sold (in an underwritten public offering or

otherwise), provided that the price obtained is based on a per share common stock price of at least the per share Purchase Price as set forth in the Stock Purchase Agreement, subject to adjustment in the event of any stock splits or combinations, stock dividends or distributions, or similar transactions involving the Acquired Securities. Additionally, in the event of an underwritten offering of WPI, Representative shall have the right to cause the sale of some or all of the Escrowed Securities in such offering and, in such case, it is agreed that Representative and Buyer shall authorize the Escrow Agent to release such number of Escrowed Securities that the Buyer desires to be sold in the underwritten public offering. In either such event, proceeds of the sale would be used to pay accrued but unpaid interest and then principal under the Notes. All such proceeds would be deposited into Escrow and released to Representative immediately after deposit.

(e) Buyer and Representative agree to promptly authorize the Escrow Agent to take action consistent with paragraphs (a), (b), (c) and (d), above, and the Escrow Agent shall make disbursements upon receipt of:

(1) a Joint Written Direction (not to be unreasonably withheld or delayed by either Party); or

(2) a copy of a final and non-appealable determination or award rendered by an arbitrator, arbitration panel or court with jurisdiction over the matter (an “Award Notice”), stating that the amount referred to in such Award Notice is payable as provided in such determination or award. An Award Notice shall be accompanied by a letter from counsel to the presenting Party that such determination or award is final, non-appealable and issued under competent jurisdiction.

(f) The Parties hereby agree to use reasonable efforts to resolve any disputes or objections relating to a request for a disbursement of any or all of the Escrow Securities and will work in good faith to timely deliver a Joint Written Direction (or resolve any disputes with respect thereto) in connection with a disbursement of any or all or the Escrow Securities.

(g) It is agreed that (i) Buyer shall have the right to vote all of the Escrow Securities on any and all matters and (ii) any dividends payable with respect to the Acquired Securities shall be considered Escrow Income and shall remain in the escrow account until disbursements are made pursuant to this Agreement.

(h) The Escrow Agent’s sole obligation with respect to the Escrow Securities shall be to deliver such Escrow Securities and associated stock powers to the appropriate party (if the entire amount of such Escrow Securities are being released) or to deliver such Escrow Securities and associated stock powers to the WPI along with appropriate instructions to (i) issue new certificates in the name of the person or party in the amount of shares such person or party is entitled to receive and (ii) issue new certificates in the name of Buyer for the balance of such Escrow Securities. The Representative agrees to deposit new associated stock powers in the event of another partial distribution of Escrow Securities. The Escrow Agent shall have no liability in the event of any mistake, delay or failure to act on the part of the stock transfer agent with respect to the Escrow Securities.

(i) Pursuant to Section 4.4(a) of the Stock Purchase Agreement, Buyer shall cause the Escrow Securities consisting of warrants to be exercised (including at Buyer’s option via so-called “cashless” exercise) immediately prior to the earlier of (i) the consummation of a Sale of WPI (as defined in the Notes) or (ii) the date of expiration of such warrants by their terms; provided that in each case Buyer shall have no obligation to cause such warrants to be exercised if, on the date of such exercise, the per share value of WPI common stock, as determined in good faith by the board of directors of WPI, is less than the per share exercise price of such warrants (i.e., the warrants are not “in the money”).

(j) Pursuant to Section 4.4(b) of the Stock Purchase Agreement, in the event of a Sale of WPI (as defined in the Notes), Buyer shall cause all Escrow Securities consisting of shares of common stock to be treated in the same manner as all other shares of WPI Common Stock in such Sale transaction. Upon such a Sale of WPI, Buyer and Representative agree to promptly authorize the Escrow Agent to take action consistent with this paragraph (j).

Section 4. Investment

During the term of this Agreement, any cash portion of the Escrow shall be invested in a money market mutual fund, including without limitation a Wells Fargo Advantage Funds Money Market Fund selected by Buyer and Representative and as set forth in Schedule 1 attached hereto, and as shall be acceptable to the Escrow Agent, based upon prospectuses previously delivered upon request to Buyer and Representative. Written investment instructions from Representative and Buyer, if any, shall specify the type and identity of the investments to be purchased and/or sold. The Escrow Agent is hereby authorized to execute purchases and sales of investments through the facilities of its own trading or capital markets operations or those of any affiliated entity. Representative and Buyer recognize and agree that the Escrow Agent will not provide supervision, recommendations or advice relating to either the investment of moneys held in the Escrow Fund or the purchase, sale, retention or other disposition of any investment described herein. Escrow Agent shall not have any liability for any loss sustained as a result of any investment in an investment made pursuant to the terms of this Agreement or as a result of any liquidation of any investment prior to its maturity or for the failure of Representative and Buyer to give the Escrow Agent instructions to invest or reinvest the Escrow Fund. Escrow Agent shall have the right to liquidate any investments held in order to provide funds necessary to make required payments under this Agreement. All Escrow Income belongs to the Frost Group Shareholders, and shall be disbursed to the Representative on behalf of the Frost Group Shareholders at the written instruction of the Representative.

Section 5. Full Release of Escrow and Representative Responsibilities

(a) When all Escrow Securities and other amounts have been released from Escrow, this Agreement shall automatically terminate; provided that Sections 8 and 9 shall survive the termination of this Agreement.

(b) Representative agrees that it shall be solely responsible for making the appropriate payments to the Frost Group Shareholders and that neither Buyer nor its affiliates shall have any liability whatsoever in connection with any such apportionment or distribution.

Section 6. Escrow Agent

(a) The Escrow Agent shall have only those duties as are specifically and expressly provided herein, which shall be deemed purely ministerial in nature, and no other duties shall be implied. The Escrow Agent shall neither be responsible for, nor chargeable with, knowledge of, nor have any requirements to comply with, the terms and conditions of any other agreement, instrument or document between the Parties, in connection herewith, if any, including without limitation the Stock Purchase Agreement, nor shall the Escrow Agent be required to determine if any person or entity has complied with any such agreements, nor shall any additional obligations of the Escrow Agent be inferred from the terms of such agreements, even though reference thereto may be made in this Agreement. In the event of any conflict between the terms and provisions of this Agreement, those of the Stock Purchase Agreement, any schedule or exhibit attached to the Escrow Agreement, or any other agreement among the Parties, the terms and conditions of this Agreement shall control. The Escrow Agent may rely upon and shall not be liable for acting or refraining from acting upon any written notice, document, instruction or request furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the

proper Party or Parties without inquiry and without requiring substantiating evidence of any kind. Concurrent with the execution of this Agreement, the Representative and Buyer shall deliver a Certificate as to Authorized Signers substantially in the form of Schedule 2 to this Agreement to the Escrow Agent, which schedule may be executed in counterparts. The Escrow Agent shall be under no duty to inquire into or investigate the validity, accuracy or content of any such document, notice, instruction or request. The Escrow Agent shall have no duty to solicit any payments which may be due it or the Fund, including, without limitation, the Escrow Deposit.

(b) The Escrow Agent shall not be liable for any action taken, suffered or omitted to be taken by it except to the extent that a final adjudication of a court of competent jurisdiction determines that the Escrow Agent’s gross negligence or willful misconduct was the primary cause of any loss to any Party. The Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through attorneys, and shall be liable only for its gross negligence or willful misconduct (as finally adjudicated in a court of competent jurisdiction) for any action taken or omitted by the Escrow Agent in accordance with the advice of counsel or other professionals retained or consulted by the Escrow Agent. The Escrow Agent may consult with counsel, accountants and other skilled persons to be selected and retained by it. In the event that the Escrow Agent shall be uncertain or believe there is some ambiguity as to its duties or rights hereunder or shall receive instructions, claims or demands from any party hereto which, in its opinion, conflict with any of the provisions of this Agreement, it shall be entitled to refrain from taking any action and its sole obligation shall be to keep safely all property held in Escrow until it shall be given a direction in writing by the Buyer and the Representative which eliminates such ambiguity or uncertainty to the satisfaction of Escrow Agent or by a final and non-appealable order or judgment of a court of competent jurisdiction. Except in the event of willful misconduct or gross negligence of the Escrow Agent, the Parties agree to pursue any redress or recourse in connection with any dispute without making the Escrow Agent a party to the same. ANYTHING IN THIS AGREEMENT TO THE CONTRARY NOTWITHSTANDING, IN NO EVENT SHALL THE ESCROW AGENT BE LIABLE FOR SPECIAL, INCIDENTAL, PUNITIVE, INDIRECT OR CONSEQUENTIAL LOSS OR DAMAGE OF ANY KIND WHATSOEVER (INCLUDING BUT NOT LIMITED TO LOST PROFITS), EVEN IF THE ESCROW AGENT HAS BEEN ADVISED OF THE LIKELIHOOD OF SUCH LOSS OR DAMAGE AND REGARDLESS OF THE FORM OF ACTION.

Section 7. Succession

(a) The Escrow Agent may resign and be discharged from its duties or obligations hereunder by giving thirty (30) days advance notice in writing of such resignation to the Parties specifying a date when such resignation shall take effect. If the Parties have failed to appoint a successor escrow agent prior to the expiration of thirty (30) days following receipt of the notice of resignation, the Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor escrow agent or for other appropriate relief, and any such resulting appointment shall be binding upon all of the parties hereto. Escrow Agent’s sole responsibility after such thirty (30) day notice period expires shall be to hold the Escrow (without any obligation to reinvest the same) and to deliver the same to a designated substitute escrow agent, if any, or in accordance with the directions of a final order or judgment of a court of competent jurisdiction, at which time of delivery Escrow Agent’s obligations hereunder shall cease and terminate, subject to the provisions of Sections 8 and 9 hereunder. The Escrow Agent shall have the right to withhold an amount equal to any amount due and owing to the Escrow Agent, plus any costs and expenses the Escrow Agent shall reasonably believe may be incurred by the Escrow Agent in connection with the termination of this Agreement.

(b) Any entity into which the Escrow Agent may be merged or converted or with which it may be consolidated, or any entity to which all or substantially all the escrow business may be

transferred, shall be the Escrow Agent under this Agreement without further act, any provision herein to the contrary notwithstanding.

(c) The Escrow Agent may be removed and discharged from its duties or obligations hereunder at any time whether or not for cause upon mutual agreement by the Parties and by delivery of a joint written notice from the Parties of such removal to the Escrow Agent specifying a date when such removal shall take effect and appointing a successor agent or providing for other appropriate relief. Escrow Agent’s sole responsibility after receipt of such joint written notice shall be to hold the Escrow (without any obligation to reinvest the same) and to deliver the same to a designated substitute escrow agent, if any, or in accordance with the directions of the joint written notice from the Parties, at which time of delivery Escrow Agent’s obligations hereunder shall cease and terminate, subject to the provisions of Sections 8 and 9 hereunder.

Section 8. Compensation and Reimbursement

Buyer and Representative agree to (i) pay the Escrow Agent’s fees in the amounts and on the dates specified in Exhibit A attached hereto, and (ii) pay or reimburse the Escrow Agent upon request for all expenses, disbursements and advances, including, without limitation reasonable attorney’s fees and expenses, incurred or made by it in connection with the preparation, negotiation, execution, performance, delivery, modification and termination of this Agreement. Buyer and Representative agree that the fees and expenses of the Escrow Agent pursuant to this Section 8 shall be borne equally by Buyer and Representative.

Section 9. Indemnity

The Parties shall jointly and severally indemnify, defend and save harmless the Escrow Agent and its affiliates and their respective successors, assigns, directors, officers, managers, attorneys, accountants, experts, agents and employees (the “indemnitees”) from and against any and all losses, damages, claims, liabilities, penalties, judgments, settlements, actions, suits, proceedings, litigation, investigations, costs or expenses (including, without limitation, the reasonable fees and expenses of outside counsel and experts and their staffs and all reasonable expense of document location, duplication and shipment) (collectively “Losses”) arising out of or in connection with (a) the Escrow Agent’s execution and performance of this Agreement, tax reporting or withholding, the enforcement of any rights or remedies under or in connection with this Agreement, or as may arise by reason of any act, omission or error of the indemnitee, except in the case of any indemnitee to the extent that such Losses are finally adjudicated by a court of competent jurisdiction to have been primarily caused by the gross negligence or willful misconduct of such indemnitee, or (b) its following any instructions or other directions, whether joint or singular, from the Parties, except to the extent that its following any such instruction or direction is expressly forbidden by the terms hereof. The Parties hereto acknowledge that the foregoing indemnities shall survive the resignation, replacement or removal of the Escrow Agent or the termination of this Agreement. The Parties hereby grant the Escrow Agent a lien on, right of set-off against and security interest in, the Fund for the payment of any claim for indemnification, fees, expenses and amounts due hereunder. In furtherance of the foregoing, the Escrow Agent is expressly authorized and directed, but shall not be obligated, to charge against and withdraw from the Escrow for its own account or for the account of an indemnitee any amounts finally determined to be due to the Escrow Agent or to an indemnitee under this Section 9. The obligations contained in this Section 9 shall survive the termination of this Agreement and the resignation, replacement or removal of the Escrow Agent.

Section 10. Patriot Act Disclosure/Taxpayer Identification Numbers/Tax Reporting

(a) Patriot Act Disclosure. Section 326 of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”) requires the Escrow Agent to implement reasonable procedures to verify the identity of any person that opens a new account with it. Accordingly, the Parties acknowledge that Section 326 of the USA PATRIOT Act and the Escrow Agent’s identity verification procedures require the Escrow Agent to obtain information which may be used to confirm the Parties identity including without limitation name, address and organizational documents (“identifying information”). The Parties agree to provide the Escrow Agent with and consent to the Escrow Agent obtaining from third parties any such identifying information required as a condition of opening an account with or using any service provided by the Escrow Agent.

(b) Taxpayer Identification Numbers (“TINs”). The Parties have provided the Escrow Agent with their respective fully executed Internal Revenue Service (“IRS”) W-9 and/or other required documentation.

(c) Tax Reporting. All cash Escrow Income or other cash income earned under this Agreement shall be allocated to the Frost Group Shareholders and all other Escrow Income earned under this Agreement shall be allocated to the Buyer and, in each case, reported, as and to the extent required by law, by the Escrow Agent to the IRS, or any other taxing authority, on IRS Form 1099 or 1042S (or other appropriate form) as income earned from the Escrow Income by the Frost Group Shareholders or Buyer, as the case may be, whether or not said income has been distributed during such year. Any income allocated to or reported as earnings against the Frost Group Shareholders shall be allocated and reported in accordance with Schedule 3 to this Agreement. Any other tax returns required to be filed with respect to the Escrow Income will be prepared and filed by Representative and/or Buyer with the IRS and any other taxing authority as required by law, including but not limited to any applicable reporting or withholding pursuant to the Foreign Investment in Real Property Tax Act (“FIRPTA”). Representative and Buyer acknowledge and agree that Escrow Agent shall have no responsibility for the preparation and/or filing of any tax return or any applicable FIRPTA reporting or withholding with respect to the Escrow Deposit or Escrow Income. In the absence of written direction from the Representative and Buyer, all proceeds of the Escrow Income shall be retained in the Escrow Income and reinvested from time to time by the Escrow Agent as provided in this Agreement. Escrow Agent shall withhold any taxes it deems appropriate, including but not limited to required withholding in the absence of proper tax documentation, and shall remit such taxes to the appropriate authorities.
