contributions to the creation or development of the Corporation Intellectual Property such that without such contributions any aspect of the Intellectual Property would not function or operate, or could not be used as intended) has executed a
customary confidentiality, non-compete, and assignment of inventions agreement, all of which have been provided to Purchasers legal counsel or has otherwise assigned to Corporation all rights, title and interest in any Intellectual Property

promote the interest of the Corporation or that would conflict with the Corporations business. Neither the execution or delivery of this Agreement or the Escrow Agreement, nor the carrying on of the Corporations business by the employees
and consultants of the Corporation, nor the conduct of the Corporations business as now conducted and as presently proposed to be conducted, will, to the Knowledge of Founding Shareholders, conflict with or result in a breach of the terms,
conditions, or provisions of, or constitute a default under, any contract, covenant or instrument under which any such employee or consultant is now obligated.

actually made contributions to an Employee Plan that is subject to the provisions of Title IV of ERISA.

(c) To the Knowledge of the
Founding Shareholders, each Employee Plan has been operated and administered in all material respects in accordance with its terms and Applicable Law, including ERISA and the Code. There are no pending or, to the Knowledge of the Founding
Shareholders, threatened audits, investigations or claims involving any Employee Plan by any Governmental Authority or other Person, other than routine claims for benefits. Each Employee Plan that is intended to be qualified within the
meaning of Section 401(a) of the Code has received a favorable determination letter from the IRS regarding its qualified status, and no fact exists, including any amendment or failure to amend any Employee Plan, that would cause the IRS to
revoke such favorable determination letter.

(d) Except (i) as may be provided in any employment Contract currently in effect between
Corporation and an Employee or former Employee, or (ii) as otherwise set forth on Schedule 2.09(d), the consummation of the transaction contemplated herein shall not (A) result in any payment becoming due, or increase the amount of
compensation due, to any Employee or former Employee or current or former director of the Corporation, (B) increase any benefits payable under any Employee Plan, or (C) accelerate the time of payment or vesting, or increase the amount of,
or otherwise enhance, any benefit due to any Employee or former Employee or current or former director of the Corporation. No such payment will result in the loss by reason of Section 280G of the Code, of any federal income Tax deduction by
Purchaser or by the Corporation.

(e) No Employee Plan provides benefits, including death or medical benefits (whether or not insured),
with respect to current or former Employees of Corporation or current or former directors of Corporation after retirement or other termination of service other than (i) coverage mandated by Sections 601-608 of ERISA and Section 4980B(f) of

(g) No leased employee (within the meaning of Section 414(n) of the Code) performs (or during the preceding three years has performed)
services for Corporation. The Corporation has at all times been in material compliance with Applicable Law regarding the classification of Employees and independent contractors. No Person engaged by either Corporation as an independent contractor,
laborer, temporary Employee, or leased employee has ever been improperly excluded from participation in a Employee Plan, nor has Corporation used the services of any such individual to an extent that would reasonably be expected to
result in the disqualification of any of the Employee Plans or the imposition of material penalties or excise Taxes with respect to the Employee Plans by the IRS, the Department of Labor, the Pension Benefit Guaranty Corporation or any other
Governmental Authority.

Founding Shareholders Knowledge, no sponsor, trustee or administrator of any Employee Benefit Plan has engaged in a transaction or has taken or failed to take any action with respect to an Employee Benefit Plan that would be reasonably
expected to subject the Corporation or an ERISA Affiliate to a civil penalty assessed pursuant to Section 502(i) of ERISA or a Tax imposed pursuant to Section 4975 or 4980B of the Code.

Section 4.06, Purchaser and the Corporation shall be entitled to seek, from any court of competent jurisdiction, preliminary and permanent injunctive relief to enforce the terms of this Section 4.06, in addition to any and
all monetary damages allowed by law, against him.

(iv) Extension of Covenants. In the event that a court determines that a Seller
violates any one or more of the covenants contained in this Section 4.06, the Seller agrees that the time periods set forth in this Section 4.06 are suspended during any period in which the Seller is breaching such covenants
and the Restricted Period shall be extended by the length of any such period of breach.

(v) Judicial Modification. The parties
expressly agree that the character, duration and geographical scope of such provisions in this Agreement are reasonable in light of the circumstances as they exist on the date upon which this Agreement has been executed. The parties have attempted
to limit each Founding Shareholders right to compete only to the extent necessary to protect Purchasers and the Corporations goodwill and other business interests. The parties recognize, however, that reasonable people may differ in
making such a determination. Consequently, the parties hereby agree that a court having jurisdiction over the enforcement of this Section 4.06 shall exercise its power and authority to reform the Founding Shareholders covenants
under this Section 4.06 to the extent necessary to cause the limitations contained therein as to time, geographic area and scope of activity to be restrained to be reasonable and to impose a restraint that is not greater than necessary
to protect Purchaser and Corporations goodwill and other business interests.

SECTION 4.07 Indemnification.

(a) Subject to the provisions of this Section 4.07 and the indemnification obligations section forth in Article V, effective as of and
after the Closing Date, Sellers shall, jointly and severally,

indemnify, defend and hold harmless Purchaser and its Affiliates, and their respective stockholders, members, partners, managers, officers, directors,
employees, representatives, controlling persons, counsel, agents, successors and assigns (Purchaser Indemnified Party), from and against all Damages, whether involving a third party claim or between the parties to this Agreement,
that any Purchaser Indemnified Party may suffer or become subject to, as and when incurred by such Purchaser Indemnified Party, as a result of (i) any inaccuracy of any representation or warranty of Sellers and the Corporation contained in this
Agreement or any other documents relating to the transaction contemplated herein (including all schedules, exhibits and annexes hereto and thereto), (ii) any breach of any covenant or agreement of Sellers contained in this Agreement or any
other documents relating to the transaction contemplated herein, and (iii) to the extent not covered by the Corporations general liability insurance policy, any product shipped or manufactured by, or any services provided by, the
Corporation prior to the Closing Date.

(b) Subject to the provisions of this Section 4.07, effective at and after the Closing
Date, Purchaser shall indemnify, defend and hold harmless Sellers, and their respective stockholders, members, partners, managers, officers, directors, employees, representatives, controlling persons, counsel, agents, successors and assigns
(Sellers Indemnified Party), from and against all Damages, whether involving a third party claim or between the parties to this Agreement, that any Sellers Indemnified Party may suffer or become subject to, as and when
incurred by such Sellers Indemnified Party, as a result of (i) any inaccuracy of any representation or warranty made by Purchaser in this Agreement or any other documents relating to the transaction contemplated herein (including all
schedules, exhibits and annexes hereto and thereto), (ii) any breach of any covenant or agreement of Purchaser contained in this Agreement or any other documents relating to the transaction contemplated herein, and (iii) all liability for
Taxes of Purchaser and taxes owed by the Corporation for all Tax periods (and portions thereof) beginning after the Closing Date.

(c) The
representations and warranties made herein shall survive the Closing until the second anniversary of the Closing Date, except that (i) the representations and warranties contained in Sections 2.01, 2.02, 2.03 and
2.05 shall survive indefinitely, (ii) the representations and warranties in Section 2.12 and Article V, dealing with Tax matters, shall survive as provided in Section 5.04; (iii) insofar as any claim is made
by the Purchaser for the breach of any representation or warranty of Founding Shareholders or the Corporation contained herein relating to environmental matters, such representation and warranty shall, for purposes of such claims by the Purchaser,
survive the Closing until the tenth anniversary of the Closing; (iv) the representations and warranties which are the basis for claims asserted under this Agreement prior to the expiration of such applicable time periods shall survive until the
final resolution of those claims and (v) insofar as any breach of any representation or warranty is the result of fraud or intentional misrepresentation then such representation or warranty shall survive the Closing without limitation.

(d) The right to indemnification, payment of Damages and other remedies based on representations, warranties, covenants and obligations in
this Agreement shall not be affected by any investigation conducted or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the
accuracy or inaccuracy of or compliance with any such representation, warranty, covenant or obligation.

(e) In the event that an
Indemnifying Party shall be obligated to indemnify Purchaser Indemnified Party or Sellers Indemnified Party as the case may be, pursuant to this Section 4.07, the Indemnifying Party shall, upon payment in full of such indemnity, be
subrogated to all rights of the Indemnified Party with respect to claims to which such indemnification relates. Without limiting the



-xxxiv-



---

foregoing, if at any time subsequent to the receipt by an Indemnified Party of an indemnity payment hereunder, such Indemnified Party (or any Affiliate of
such Indemnified Party) receives any recovery, settlement or other similar payment with respect to any Damage incurred by Sellers or Purchaser, as the case may be, for which such Indemnified Party received such indemnity payment, such Indemnified
Party shall promptly pay to the Indemnifying Party an amount equal to the amount of such payment, less any expense incurred by such Person in connection with such payment; provided that nothing herein shall require Purchaser to submit or seek
recovery under Purchasers insurance policies for any Damages for which Seller is required to indemnify Purchaser hereunder.

(f) For
the purpose of determining the amount of any Damages that are the subject matter of a Claim for indemnification hereunder, each representation and warranty contained in this Agreement shall be read without regard and without giving effect to any
materiality or Material Adverse Effect standard or qualification contained in such representation or warranty.

SECTION 4.08 Defense of Claims. If a claim for Damages (a Claim) is to be made by a Purchaser Indemnified Party or a Seller Indemnified Party (an Indemnified Party), such Indemnified Party shall
give notice (a Claim Notice) to (i) Seller Representatives, in the case of an indemnification claim pursuant to Section 4.07(a) or (ii) Purchaser, in the case of an indemnification claim pursuant to
Section 4.07(b) (Indemnifying Party), in either case as soon as practicable after such Indemnified Party becomes aware of any fact, condition or event which may reasonably give rise to Damages for which indemnification
may be sought under this Section 4.08; however, the failure of any Indemnified Party to give timely notice hereunder shall not affect rights to indemnification hereunder, except to the extent such Indemnified Party is actually prejudiced
by such failure (to the extent determined by a court of competent jurisdiction). If any proceeding is filed or instituted making a claim against any Indemnified Party with respect to a matter subject to indemnity hereunder, notice thereof shall be
given to the Indemnifying Party as promptly as practicable; however, the failure of any Indemnified Party to give timely notice hereunder shall not affect rights to indemnification hereunder, except to the extent such Indemnified Party is actually
prejudiced by such failure (to the extent determined by a court of competent jurisdiction). After receipt of such a notice of a proceeding, the Indemnifying Party shall have the right to defend the Indemnified Party against the proceeding at the
Indemnifying Partys expense with counsel of its choice satisfactory to the Indemnified Party, unless the nature of the claim creates an ethical conflict or otherwise makes it inadvisable for the same counsel to represent the Indemnified Party
and the Indemnifying Party, so long as (a) the Indemnifying Party notifies the Indemnified Party in writing within fifteen (15) days after the Indemnified Party has given notice of the claim or proceeding that the Indemnifying Party will
indemnify the Indemnified Party from and against the entirety of any Damages the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the claim or raised in the proceeding, (b) the
Indemnifying Party provides the Indemnified Party with evidence reasonably acceptable to the Indemnified Party that the Indemnifying Party will have the financial resources to defend against the proceeding and fulfill its indemnification obligations
hereunder, (c) the proceeding involves only a claim for money damages and no other relief and (d) the Indemnifying Party conducts the defense of the proceeding actively and diligently. The Indemnifying Party shall not compromise or settle
any such proceeding without the prior written consent of the Indemnified Party or enter into any settlement negotiations in connection with such proceeding without giving prior written notice to the Indemnified Party. In all other cases the
Indemnified Party may defend the claim or proceeding with counsel of its choosing at the expense of the Indemnifying Party. The Indemnified Party may, at its own cost, participate in the investigation, trial and defense of any such proceeding
defended by the Indemnifying Party and any appeal arising therefrom and employ its own counsel in connection therewith. The parties shall cooperate with each other in connection with any defense in any notifications to insurers. If the Indemnifying
Party fails to promptly and diligently assume the defense of such



-xxxv-



---

proceeding after receipt of notice hereunder, the Indemnified Party against which such claim has been asserted shall (upon delivering notice to such effect
to the Indemnifying Party) have the right to undertake the defense, compromise or settlement of such proceeding with counsel of its own choosing at the expense of the Indemnifying Party and the Indemnifying Party shall have the right to participate
therein at its own cost.

SECTION 4.09 Distributions from the Escrow Fund. In the event that (a) the Seller Representatives
shall not have objected to the amount claimed by the Purchaser for indemnification with respect to any Damages in accordance with the procedures set forth in the Escrow Agreement, or (b) the Seller Representatives shall have delivered notice of
their disagreement as to the amount of any indemnification requested by the Purchaser and either (i) the Seller Representatives and the Purchaser shall have, subsequent to the giving of such notice, mutually agreed that the Sellers are
obligated to indemnify the Purchaser for a specified amount and shall have so jointly notified the Escrow Agent or (ii) a final nonappealable judgment shall have been rendered by the court having jurisdiction over the matters relating to such
claim by the Purchaser for indemnification from the Sellers and the Escrow Agent shall have received, in the case of clause (i) above, written instructions from the Seller Representatives and the Purchaser or, in the case of clause
(ii) above, a copy of the final nonappealable judgment of the court, the Escrow Agent shall deliver to the Purchaser from the Escrow Fund any amount determined to be owed to the Purchaser under this Section 4.09, in accordance with
the Escrow Agreement. Pursuant to the Escrow Agreement, in the event that one or more of the Milestones set forth in Schedule 1.05 are not fully achieved by the end of 24 months from the date hereof, the Escrow Agent shall return all
remaining amounts in the Escrow Fund to Purchaser and the Seller Representatives will provide written instructions directing the Escrow Agent to make such distribution.

SECTION 4.10 Limits on Indemnification. Notwithstanding anything to the contrary contained in this Agreement, except with respect to claims relating to Taxes as set forth in Article V: (a) an Indemnifying
Party shall not be liable for any claim for indemnification pursuant to Section 4.07, unless and until the aggregate amount of indemnifiable Damages which may be recovered from the Indemnifying Party equals or exceeds $75,000, after
which the Indemnifying Party shall be liable only for those Damages in excess of $75,000; and (b) the maximum amount of indemnifiable Damages which may be recovered from an Indemnifying Party (i) arising out of or resulting from the causes
set forth in Section 4.07(a) shall be an amount equal to his or her pro rata portion of the Purchase Price as indicated by the number of Shares held by such Seller as set forth on Schedule 1.02 and (ii) if arising out of or
resulting from the causes set forth in Section 4.07(b) shall be an amount equal to the pro rata portion of the Purchase Price received by such Seller seeking indemnification under Section 4.07(b) as indicated by the number of
Shares held by such Seller as set forth on Schedule 1.02. The provisions of this Section 4.10 shall not apply with respect to indemnification for (i) Taxes, including any representations or warranties made in
Section 2.12 or Article V, (ii) the representations and warranties contained in Sections 2.01, 2.02, 2.03, 2.05, or 2.28, or (iii) any breach of any representation or warranty as a result of fraud or
intentional misrepresentation.

SECTION 4.11 Use of Intellectual Property. The Sellers acknowledge that from and after the Closing
Date, the name of the Corporation and all similar or related names, marks and logos (all of such names, marks and logos being the Corporation Marks) shall be owned by the Corporation, that neither the Sellers nor any of their
Affiliates shall have any rights in the Corporation Marks and that neither the Sellers nor any of their Affiliates will contest the ownership or validity of any rights of the Purchaser or the Corporation in or to the Corporation Marks.

SECTION 4.12 Schedules.



-xxxvi-



---

(a) The parties shall promptly revise or supplement their respective Schedules hereto upon the occurrence
of any event or change in condition that would render any Schedule hereto incorrect or incomplete as of the Closing Date to reflect information learned of or that came into existence after the date hereof and that would have been required to be
disclosed on one or more Schedules hereto if such information was known or in existence on the date hereof.

(b) The disclosure of any
matter, event, condition or state of facts in any Schedule to this Agreement, as may be amended or supplemented prior to the Closing shall expressly not be deemed to constitute an admission by Sellers, the Corporation or Purchaser, or to otherwise
imply, that any such matter is material for the purposes of this Agreement. Any updates shall not serve as a basis to qualify the Sellers representations or warranties unless accepted by Purchaser.

(c) In the event of any inconsistency between the statements in the body of this Agreement and any Schedule (other than an exception expressly set forth
as such in such Schedule with respect to a specifically identified representation or warranty), the statements in the body of this Agreement will control.

SECTION 4.13 Exclusivity. Beginning on the date of the execution of this Agreement through September 30, 2007 (Exclusivity Period), Sellers will not, and Sellers will cause Corporation,
and all the respective officers, directors, employees, agents, stockholders or representatives of such parties, not to, directly or indirectly, encourage, solicit, initiate or participate in discussions or negotiations with, or provide any
information to, and cease all discussions and negotiations with, any third party (other than Purchaser) concerning, or otherwise facilitate, any acquisition, merger or business combination or the sale or license of all or any material portion of the
Corporations assets, securities, or other similar transaction or any sale of debt or equity securities involving the Corporation.

SECTION 4.14 Leases. Prior to the Closing, Sellers shall use reasonable commercial efforts where necessary to enter into amendments to its leases or obtain landlords consents related to the change in control of the Corporation
contemplated by this Agreement; provided that Sellers shall be responsible for all expenses associated with the leases in excess of the rental and other fees set forth on Schedule 2.10(a) resulting from lease amendments referred to herein.

SECTION 4.15 Sellers Post Closing Release. Effective as of the Closing Date, and subject to the payment of all amounts due
Sellers from Purchaser hereunder, each Seller hereby releases and discharges the Corporation and any of its affiliates (whether in such Sellers capacity as a shareholder, director, officer, employee or otherwise) from any and all claims,
demands and causes of action, whether known or unknown, liquidated or contingent, relating to, arising out of or in any way connected with the dealings of the Corporation or its affiliates, and such Seller from the beginning of time through the
Closing, it being understood, however, that such release shall not operate to release the Corporation or Purchaser from any obligations under this Agreement. Each Seller acknowledges that the Legal Requirements of many states provide substantially
the following: A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER
SETTLEMENT WITH THE DEBTOR. Each Seller acknowledges that such provisions are designed to protect a party from waiving claims which it does not know exist or may exist. Nonetheless, each Seller agrees that, effective as of the Closing, such
Seller shall be deemed to waive any such provision. Each Seller further agrees that such Seller shall not (i) institute any action, arbitration, audit, hearing, investigation, litigation, or suit (whether civil, criminal, administrative,
investigative, or informal) commenced, brought, conducted, or heard by or



-xxxvii-



---

before, or otherwise involving, any governmental body or arbitrator (Proceeding) based upon, arising out of, or relating to any of the
released claims, (ii) participate, assist, or cooperate in any such Proceeding, or (iii) encourage, assist and/or solicit any third party to institute any such Proceeding.

SECTION 4.16 Tax Receipts. Sellers Representatives shall assist Purchaser in obtaining a receipt or certificate for the Corporation from each
state in which the Corporation files Tax Returns showing that all state and local Taxes have been paid by Corporation.

SECTION 4.17
Confidentiality.

(a) For purposes of this Agreement, Confidential Information includes, but is not limited to, the
following information, which is the confidential, proprietary information, and trade secrets of the Corporation: (1) customer lists, consultant lists, and customer information as compiled by the Corporation, including customer orders, product
usage, product volumes, pricing, customer technology, sale and contract terms, contract expiration dates, and other compiled customer information; (2) the Corporations own internal practices and procedures, compensation and payroll
information, and personnel data; (3) the Corporations financial condition and financial results of operations; (4) supply of materials information, including sources and costs; (5) information relating to designs, formula,
developmental or experimental work, know-how, products, processes, computer programs, source codes, data bases, designs, schematics, inventions, creations, original works of authorship, or other subject matter relating to the Corporations
research and development, strategic planning, manufacturing, engineering, purchasing, finance, marketing, promotion, distribution, licensing, and selling activities; (6) all information which Seller has a reasonable basis to consider
confidential or which is treated by the Corporation as confidential; and (7) any and all information, whether in oral or written form, having independent economic value to the Corporation that is not generally known to, and not readily
ascertainable by proper means by a person who can obtain economic value from its disclosure or use. Confidential Information shall also include information which, though not specifically disclosed to Seller by the Corporation, is made available to
Seller through Sellers access to or inspection of the Corporations facilities or products. Excluded from this paragraph is information that is already disclosed to third parties by proper means and is in the public domain.

(b) Seller shall not directly or indirectly disclose, utilize, or authorize any disclosure of Confidential Information to any third person or party.

| | (i) | any and all Taxes (or the non-payment thereof) of Sellers and the Corporation for all Pre-Closing Tax Periods, and the portion of any Straddle Period that ends on the Closing Date,
as determined in Section 5.01(c);

Section 2.12 and this Article V;
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | any and all Taxes (or the non-payment thereof) of any Person (other than the Corporation) imposed on the Sellers or the Corporation as a transferee or successor by contract or
pursuant to any Law, rule or regulation, which Taxes relate to an event or transaction occurring on or before the Closing Date; and

of Taxes (or the non-payment thereof) of the Corporation for a Straddle Tax Period, the determination of the Taxes for the portion of the Straddle Tax Period (1) beginning prior to the Closing Date and ending on the Closing Date, and
(2) beginning the day after the Closing Date, shall be determined:



| | (i) | in the case of Taxes that are either (x) based upon or related to income or receipts, or (y) imposed in connection with any distribution, sale or other transfer or
assignment of property, by assuming that the Corporation had a taxable year or period which ended at the close of the Closing Date and closing the books of the Corporation as of such date (and for such purpose the taxable period of any partnership,
joint venture or other pass-through entity in which the Corporation holds a beneficial interest shall be deemed to terminate at such time), except that exemptions, allowances or deductions that are calculated on an annual basis, such as the
deduction for depreciation, shall be apportioned on a time basis; and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | in the case of Taxes not described in clause (i) that are imposed on a periodic basis and measured by the level of any item, shall be deemed to be the amount
of such Taxes (including any minimum) for the entire period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period) multiplied by a fraction the numerator of which is the number
of calendar days in the period determined in clause (1) above and the denominator of which is the number of calendar days in the entire Straddle Tax Period. In the case of any Tax based upon or measured by capital (including net worth or
long-term debt) or intangibles, any amount thereof required to be allocated under this subsection shall be computed by reference to the level of such items on the Closing Date. All determinations necessary to

| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(d) S Corporation Status. Corporation and Sellers shall not revoke Corporations election to be taxed as an S corporation within the meaning
of Code Sections 1361 and 1362. Corporation and Sellers shall not intentionally take or intentionally allow any action that would result in the termination of Corporations status as a validly electing S corporation within the meaning of Code
Sections 1361 and 1362.

(e) Tax Periods Ending on or before Closing Date. Purchaser shall prepare or cause to be prepared and
file or cause to be filed all Tax Returns for Corporation for all periods ending on or prior to the Closing Date that are filed after the Closing Date. With respect to Corporations short-year income Tax Return, Purchaser and
SellerRepresentatives shall mutually agree to such return prior to filing, provided that any comments to such return submitted by Seller Representatives are permitted by law. If Purchaser and SellerRepresentatives are
unable to mutually agree on such return, then the Parties shall refer any dispute to an independent national accounting firm, whose decision shall be binding on both Parties. To the extent permitted by applicable law, Purchaser shall
report on the Corporations short-year income Tax Return and allocate to the Sellers individual K-1s the compensation deduction attributable to the exercise of Sellers options. Further, to the extent permitted by applicable law, Sellers
shall include any income, gain, loss, deduction or other Tax items for such periods on their Tax Returns in a manner consistent with the Schedule K-1s furnished by Corporation to Sellers for such periods.

(f) Cooperation on Tax Matters.



| | (i) | Purchaser, Corporation and Sellers shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax returns and any audit,
litigation, or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other partys request) the provision of records and information reasonably relevant to any such audit, litigation, or other
proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Corporation, Sellers and Purchaser agree (A) to retain all books and records with
respect to Tax matters pertinent to Corporation relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations (and, to the extent notified by Purchaser or Sellers, any extensions thereof), of the
respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other party reasonable written notice prior to transferring, destroying, or discarding any such books and
records and, if the other party so requests, Corporation or Sellers, as the case may be, shall allow the other party to take possession of such books and records.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (ii) | Purchaser and Sellers further agree, upon request, to use their best efforts to obtain any certificate or other document from any governmental authority or any other Person as may
be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby).
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Except as otherwise required by Law, or with the consent of the Purchaser, the Sellers covenant and agree that they shall not file or amend any Tax Return, file any claim for
refund, change any method of Tax accounting, surrender any right to claim a refund of Taxes, consent to any extension or waiver of the limitation period applicable to any Tax claim or assessment relating to the Corporation, enter into any closing
agreement, settle or compromise any federal, state, local or foreign Tax liability or claim regarding the Corporation, or make or change any Tax election with respect to any Tax period, in each case that may result in any increased Tax liability of,
or loss of Tax benefits by, the Purchaser or the Corporation. Nothing in this Article shall prohibit Purchaser (or the Corporation, if directed by Purchaser) to amend, refile, or otherwise modify (or grant an extension of any statute of limitations
with respect to) any Tax Return relating in whole or in part to the Corporation with respect to any taxable year or period ending on or before the Closing Date or with respect to any Straddle Period provided such amendment, refiling, modification,
or extension will (i) be mutually agreed upon by Purchaser and a SellerRepresentative prior to filing so long as any comments to such return submitted by Seller Representative are permitted by law, and (ii) not have an adverse
affect on the liability of the Sellers or the Corporation for which Sellers are liable pursuant to this Agreement.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(g)
Tax-Sharing Agreements. All tax-sharing agreements or similar agreements with respect to or involving the Corporation shall be terminated as of the Closing Date and, after the Closing Date, Corporation shall not be bound thereby or have any
liability thereunder.

(h) Certain Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees
(including any penalties and interest) incurred in connection with this Agreement shall be paid by Sellers when due, and Sellers shall, at their own expense, file all necessary Tax Returns and other documentation with respect to all such transfer,
documentary, sales, use, stamp, registration, and other Taxes and fees, and, if required by applicable law, Purchaser shall, and shall cause its affiliates to, join in the execution of any such Tax Returns and other documentation.

(i) Filings. Purchaser and Sellers agree, upon request, to provide the other Party with all information that either Party may be required to
report pursuant to Code Section 6043, Code Section 6043A, or any other Section of the Code and all Treasury Regulations promulgated thereunder.

SECTION 5.02 §338(h)(10) Election.

(a) Election. At Purchasers option, Purchaser
and Sellers shall join in making an election under Code Section 338(h)(10) (and any corresponding election under state, local, or foreign tax law), with respect to the purchase and sale of the Corporations stock hereunder (collectively,



-xli-



---

a §338(h)(10) Election). Sellers shall include any income, gain, loss, deduction, or other tax item resulting from the
§338(h)(10) Election on their Tax Returns to the extent required by applicable law and will pay any Tax attributable to the making of a §338(h)(10) Election. Sellers shall also pay any Tax imposed on Corporation attributable to the making
of the §338(h)(10) Election , including (i) any Tax imposed under Code §1374, (ii) any tax imposed under Treas. Reg. §1.338(h)(10)-1(e)(5), or (iii) any state, local or foreign Tax imposed on the Corporations
gain; provided, however, that all such taxes are included in the Gross-Up Amount and paid by Purchaser to Sellers as provided herein. The obligation of Purchaser to pay the Gross-Up Amount to Sellers is intended to equal the amount of incremental
Taxes owed by Sellers resulting from making the §338(h)(10) Election, so that Sellers incremental Tax liability resulting from such election is, by way of the Gross-Up Amount, borne by Purchaser.

(b) Form 8023. Within ninety (90) days following the Closing Date, Purchaser shall prepare Form 8023 and submit the form to the Sellers for
their approval, which shall not be unreasonably withheld. If Purchaser has failed to provide Form 8023 to Sellers (or Sellers representative for distribution to Sellers) within ninety (90) days of the Closing Date, then Sellers may (but
shall have no obligation to) prepare such form and submit such form to Purchaser for its approval, which shall not be unreasonably withheld. If submitted by either party, all Sellers shall timely execute and file the Form 8023.

(c) Allocation of Purchase Price. The Parties agree that the Purchase Price and the liabilities of the Corporation (plus other relevant items)
will be allocated to the assets of the Corporation for all purposes (including Tax and financial accounting purposes) as shown on the allocation scheduled (the Allocation Schedule) attached hereto as Schedule 5.02(c), which
was agreed to by the Parties and prepared in a manner consistent with Code Sections 338 and 1060, and the Treasury Regulations thereunder. Any subsequent adjustments pursuant to this Agreement to the sum of the Purchase Price and liabilities shall
be reflected in the Allocation Schedule in a manner consistent with Sections 338 and 1060, and the Treasury Regulations thereunder. Purchaser, Corporation and Sellers shall timely file all Tax Returns (including Form 8883, amended returns and claims
for refund) and information reports in a manner consistent with this Agreement including the Allocation Schedule, as amended, and none of them will take any position inconsistent therewith in any Tax Return, in any refund claim, in any litigation,
or otherwise. If, pursuant to this Agreement, the amount allocated to any asset is increased or decreased after the filing of the Form 8883, then the parties shall timely file a supplemental Form 8883 in a manner consistent with this Agreement, Code
Sections 338, 1060, and the Treasury Regulations thereunder.

(d) Valid §338(h)(10) Election. Without limiting the obligations
of Sellers pursuant to this Article V, if a §338(h)(10) Election is made with respect to the acquisition of the stock of the Corporation, then Purchaser and Sellers acknowledge that if Purchaser had purchased the assets of the
Corporation directly, rather than its outstanding stock, and Purchaser had neither assumed nor purchased such assets subject to any Tax obligations of the Corporation or Sellers, then Purchaser would not have any obligation for the Taxes
of the Corporation or Sellers for the period ending as of the Closing. Purchaser and Sellers intend and agree that the Tax indemnification obligations of Sellers set forth in this Article V shall be applied to indemnify and hold Purchaser and
Corporation harmless, at a minimum, from the same Taxes that would have remained the obligation of Sellers, if the Parties had effected the transactions contemplated by this Agreement as a direct purchase of the Corporations assets by
Purchaser, and the Corporation had been liquidated, with Seller succeeding to the Corporations pre-Closing Tax liabilities, including the Tax liabilities arising from such sale and liquidation.

SECTION 5.03 Timing and Treatment of Payments.



-xlii-



---

(a) Payment by the Sellers of any amounts due under this Article V shall be made at the
earlier of (a) at least three Business Days before the due date of the applicable Tax Return required to be filed by the Purchaser for which the Sellers are responsible under this Article V, (b) within three Business Days following
earlier of the establishment of the Sellers responsibility that an indemnity amount is payable to the Purchaser pursuant to this Article V, or following the payment of Taxes by the Purchaser or the Corporation.

(b) Notwithstanding subsection (a) above, if liability under this Article V is in respect of costs or expenses other than Taxes, payment
by the Sellers of any amounts due under this Article V shall be made within five Business Days after the date when the Sellers have been notified by the Purchaser that the Sellers have a liability for a determinable amount under this
Article V and is provided with calculations or other materials supporting such liability.

(c) Purchaser and Sellers agree that
any payments made under this Article will be treated by the parties on their Tax Returns as an adjustment to the Purchase Price.

SECTION
5.04 Survival.

(a) General. Notwithstanding any provisions of this Agreement to the contrary, this Article V and the
representations and warranties set forth in Section 2.12, shall survive and shall remain in effect until 90 days after the expiration of all applicable statute of limitations and shall survive any death, corporate reorganization,
dissolution or liquidation of the Sellers, the Purchaser or the Corporation. Notwithstanding anything to the contrary in this Agreement, the Tax indemnification obligations of the Sellers are not subject to any threshold requirement relating to the
amount to be reimbursed or, except as set forth in Section 5.04(b), any ceiling on the maximum amount subject to indemnification, and Purchaser shall not be treated as having assumed the risk of any Taxes by reason of the closing of the
transaction or by reason of any knowledge that the Purchaser had or should have had about the Sellers or the Corporations Tax obligations, notwithstanding any other provision of this Agreement to the contrary.

(b) §338(h)(10) Limitation. If the transactions contemplated by this Agreement are not consummated in conjunction with the §338(h)(10)
Election contemplated by Section 5.02, then Sellers and Purchaser agree as follows:

(i) Covenant to Inform Others. If
any of Sellers, Sellers Representatives, Corporation, Purchaser or any of their affiliates is notified, in writing or otherwise, that the §338(h)(10) Election will not apply to the transactions contemplated by this Agreement, then such
Person covenants to immediately inform all Sellers, Sellers Representatives, Corporation and Purchaser of such information.

(ii)
Covenant to File Tax Return. If the §338(h)(10) Election will not apply to the transactions contemplated by this Agreement, then Purchaser shall timely notify each Seller that they should file an amended income Tax Return in order to
claim a refund for their share of the Gross Up Amount. Purchaser, at its own cost and expense, shall hire a certified public accounting firm to prepare the amended returns on behalf of each Seller, and each seller hereby names and appoints Purchaser
its attorney-in fact, with full power of substitution, to act for and file such amended returns on behalf of Seller and Seller further agrees to otherwise cooperate in all reasonable respects with Purchaser in preparing such Sellers amended
Tax Return. Purchaser shall be solely responsible for the preparation and filing of all Seller amended income Tax Returns. Upon the actual receipt of any Tax refund resulting form the filing of the amended Tax Returns, such Seller shall promptly
remit such payment or refund to Purchaser.



-xliii-



---

(iii) Acknowledgement. Notwithstanding anything to the contrary contained herein, Purchaser
acknowledges that Sellers only liability arising from the failure of the §338(h)(10) Election shall be to (x) remit to Purchaser any Tax refund received by Sellers under this Section 5.04(b), and (y) remit to Purchaser any
portion of the Gross-Up Amount received by Sellers, which were not paid or otherwise remitted with respect to Sellers Tax Returns. The exception provided in (y) is intended to cover situations where the Gross-Up Amount did not go to pay a
Sellers taxes. For example, if a Seller has a tax loss carryforward and uses that tax loss carryforward to offset the income resulting from the §338(h)(10) Election then they will not have to use the Gross-Up amount to pay taxes.

possession to each Seller in an amount set forth opposite such Sellers name on Schedule 1.04. The above distributions shall be subject to the provisions of Section 8.01(d).

(d) Payment to the Sellers Representative designated in Schedule 1.04 of the Purchase Price or any other amount payable hereunder by Purchaser to
