 EQUITY COMMITMENT AGREEMENT 
 May 10, 2006 
 J.P. Morgan Securities Inc. 
 270 Park Avenue 
 New York, New York 10017 
 Ladies and Gentlemen: 
 Subject to the approval of this Agreement by the Bankruptcy Court (as defined below), Owens Corning, a Delaware corporation (as a debtor-in-possession and a reorganized debtor, as applicable, the “Company”), proposes to
offer and sell shares of its new common stock, par value $0.10 per share, to be issued pursuant to its Amended Plan (as defined below) (together with any associated share purchase rights other than the Rights (as defined below), “New Common
Stock”), pursuant to a rights offering (the “Rights Offering”) whereby each holder of a Bondholder Claim, and each Holder of an Allowed Class A6-A Claim or an Allowed Class A6-B Claim (each an “Eligible Holder”),
as of the date (the “Record Date”) fixed by the Bankruptcy Court for the solicitation of acceptances and rejections of the Amended Plan, shall be offered the right (each, a “Right”) to purchase up to its Pro Rata
share of 72,900,000 shares (each a “Share”) of New Common Stock at a purchase price of $30.00 per Share (the “Purchase Price”). Each capitalized term used but not defined in this letter (the
“Agreement”) shall have the meaning given to it in the Fifth Amended Joint Plan of Reorganization for Owens Corning and its Affiliated Debtors and Debtors-In-Possession filed on December 31, 2005 (as it may have been amended or
supplemented, the “Existing Plan”). 
 In order to facilitate the Rights Offering, pursuant to this Agreement, and subject
to the terms, conditions and limitations set forth herein, J.P. Morgan Securities Inc. (the “Investor”), agrees to purchase on the Closing Date (as defined in Section 2), and the Company agrees to sell, for the Purchase Price
per share, a number of shares of New Common Stock equal to 72,900,000 minus the number of shares of New Common Stock offered pursuant to the Rights Offering purchased on or before the Expiration Time (as defined below) in the Rights Offering (such
Shares in the aggregate, the “Unsubscribed Shares”). 
 The Company will conduct the Rights Offering pursuant to an amended
plan of reorganization (the “Amended Plan”), which shall include only those revisions, modifications and amendments to the Existing Plan as necessary to incorporate the Company’s proposed restructuring transactions described in
the term sheet attached hereto as Exhibit A (the “Settlement Term Sheet”) and such other revisions, modifications and amendments that the Company and the other proponents of the Amended Plan (“Amended Plan
Proponents”) deem necessary or appropriate and that shall not (i) materially adversely affect the obligations or rights of the Investor hereunder, (ii) cause any representation or warranty contained herein to be incorrect or
(iii) be inconsistent with the terms of the Settlement Term Sheet, and shall be approved by the court (together with the applicable District Court, to the extent District Court approval of the Amended Plan is sought or required, the
“Bankruptcy Court”) administering the Company’s proceedings (the “Proceedings”) under the United States Bankruptcy Code, 11 U.S.C. §§ 101, et seq. (the “Bankruptcy Code”). 

 Simultaneously with the delivery of this Agreement, (i) the Company (subject, however, to Bankruptcy
Court approval), the Asbestos Claimants Committee, the Future Claimants’ Representative and certain Bondholders have entered into the Lockup Agreement, attached hereto as Exhibit B (the “Lock-Up Agreement”) and
(ii) the Investor and certain Persons (collectively, the “Ultimate Purchasers”) have entered into a syndication agreement (the “Syndication Agreement”), pursuant to which the Ultimate Purchasers have agreed to
purchase certain Unsubscribed Shares from the Investor in the event the Investor purchases Unsubscribed Shares under this Agreement. 
 In
consideration of the foregoing, and the representations, warranties and covenants set forth herein, and other good and valuable consideration, the Company and the Investor agree as follows: 
 1. The Rights Offering. The Rights Offering will be conducted as follows: 
 (a) Subject to the terms and conditions of this Agreement (including Bankruptcy Court approval), the Company hereby undertakes to offer Shares for subscription by holders of Rights as set forth in this Agreement.

 (b) In connection with the Amended Plan the Company shall issue Rights to purchase 72,900,000 Shares in the aggregate. Each Eligible
Holder as of the Record Date will receive a Right to purchase up to its Pro Rata share of 72,900,000 Shares. The ballot form(s) (the “Ballots”) distributed in connection with the solicitation of acceptance of the Amended Plan shall
provide a place whereby each Eligible Holder may exercise its Right. The Rights may be exercised during a period (the “Rights Exercise Period”) specified in the Amended Plan, which period will commence on the date the Ballots are
distributed and will end at the Expiration Time. For the purposes of this Agreement, the “Expiration Time” means 5:00 p.m. New York City time on the 20th calendar day (or if such day is not a Business Day, the next Business Day)
after the date the Ballots are distributed under the Amended Plan, or such later date as the Company, subject to the approval of the Investor (which shall not be unreasonably withheld) and the reasonable consent of the other Amended Plan Proponents,
may specify in a notice provided to the Investor before 9:00 a.m. New York City time on the Business Day before the then-effective Expiration Time. For the purposes of this Agreement, “Business Day” means each Monday, Tuesday,
Wednesday, Thursday and Friday that is not a day on which banking institutions in New York City are generally authorized or obligated by law or executive order to close. Subject to the approval of this Agreement by the Bankruptcy Court, the Amended
Plan shall provide that in order to exercise a Right, each Eligible Holder shall, prior to the Expiration Time, (i) return a duly executed Ballot to the Subscription Agent (as defined below) and (ii) pay an amount equal to the full
purchase price of the number of shares of New Common Stock elected to be purchased by such Eligible Holder by wire transfer of immediately available funds reasonably in advance of the date on which the hearing to confirm the Amended Plan is
scheduled to commence (the “Confirmation Hearing”) to an escrow account established for the Rights Offering. 
  

 -2- 

 (c) There will be no over-subscription rights provided in connection with the Rights Offering.

 (d) The Company will issue the Shares to the Eligible Holders with respect to which Rights were validly exercised by such holder upon the
effective date of the Amended Plan (the “Effective Date”). If the exercise of a Right would result in the issuance of a fractional share of New Common Stock, then the number of shares of New Common Stock to be issued in respect of
such Right will be calculated to one decimal place and rounded down to the next lower whole share. 
 (e) The Amended Plan will provide that
the Company or the Subscription Agent (as defined below) will give notice to each Eligible Holder with respect to which Rights were validly exercised by such holder, advising them of (i) the number of whole shares of New Common Stock that they
are bound to purchase pursuant to the Rights Offering, and the aggregate purchase price thereof and (ii) the date or time after the notice by which a wire transfer of such purchase price must be received and (iii) wire transfer
instructions for wiring such purchase price to the subscription agent for the Rights Offering (the “Subscription Agent”) or another person designated by the Company. 
 (f) The Company hereby agrees and undertakes to give the Investor by electronic facsimile transmission the certification by an executive officer of the
Company conforming to the requirements specified herein for such certification of either (i) the number of Unsubscribed Shares and the aggregate Purchase Price therefor (a “Purchase Notice”) or (ii) in the absence of any
Unsubscribed Shares, the fact that there are no Unsubscribed Shares and that the Backstop Commitment (as defined below) is terminated (a “Satisfaction Notice”) as soon as practicable after the Expiration Time and, in any event,
reasonably in advance of the Closing Date (to be specified in the Agreement Order) (the date of transmission of confirmation of a Purchase Notice or a Satisfaction Notice, the “Determination Date”).

order or judgment was appealed, from which certiorari was sought or to which the request was made and no further appeal or petition for certiorari has been or can be taken or granted. 
 (b) On the basis of the representations and warranties herein contained, but subject to the entry of the Agreement Order, the Company will pay to the
Investor a backstop fee of $100,000,000 (the “Backstop Fee”) to compensate the Investor for the risk of its undertaking herein. The Backstop Fee will be paid in U.S. dollars on the first Business Day after the tenth day after the

liability or expense in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party on the one hand and such Indemnified Person on the other hand but also the relative fault of the Indemnifying
Party, on the one hand, and such Indemnified Person, on the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Indemnifying Party on the one hand and all Indemnified Persons on the
other hand shall be deemed to be in the same proportion as (i) the total value received or proposed to be received by the Company pursuant to the sale of Shares contemplated by this Agreement bears to (ii) the fee paid or proposed to be
paid to the Investor in connection with such sale. The Indemnifying Party also agree that no Indemnified Person shall have any liability based on their exclusive or contributory negligence or otherwise to the Indemnifying Party, any person asserting
claims on behalf of or in right of any of the Indemnifying Party, or any other person in connection with or as a result of the Rights Offering, the Backstop Commitment, the Transaction Documents, the Registration Statement, the Prospectus or the
transactions contemplated thereby, except as to any Indemnified Person to the extent that any losses, claims, damages, liability or expenses incurred by the Company are finally judicially determined to have resulted from (i) bad faith, gross
negligence or willful misconduct of such Indemnified Person in performing the services that are the subject of this Agreement or the Registration Rights Agreement or (ii) statements or omissions in the Registration Statement or Prospectus or
any amendment or supplement thereto made in reliance upon or in conformity with information relating to the Investor or the Ultimate Purchaser furnished to the Company in writing by or on behalf of the Investor or the Ultimate Purchaser expressly
for use in the Registration Statement or Prospectus or any amendment or supplement thereto; provided, however, that in no event shall an Indemnified Person or such other parties have any liability for any indirect, consequential or punitive damages
in connection with or as a result of any of their activities related to the foregoing. The indemnity, reimbursement and contribution obligations of the Indemnifying Party under this Section 8 shall be in addition to any liability that
the Indemnifying Party may otherwise have to an Indemnified Person and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Indemnifying Party and any Indemnified Person. 
 (b) Promptly after receipt by an Indemnified Person of notice of the commencement of any claim, litigation, investigation or proceeding relating to the
Transaction Documents, the Registration Statement, the Prospectus or any of the transactions contemplated thereby (“Proceedings”), such Indemnified Person will, if a claim is to be made hereunder against the Indemnifying Party in
respect thereof, notify the Indemnifying Party in writing of the commencement thereof; provided that (i) the omission so to notify the Indemnifying Party will not relieve it from any liability that it may have hereunder except to the extent it
has been materially prejudiced by such failure and (ii) the omission so to notify the Indemnifying Party will not relieve it from any liability that it may have to an Indemnified Person otherwise than on account of this Section 8. In
case any such Proceedings are brought against any Indemnified Person and it notifies the Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein, and, to the extent that it may elect by written
notice delivered to such Indemnified Person, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Person, provided that if the defendants in any such Proceedings include both such Indemnified Person and the
Indemnifying Party and such Indemnified Person 
  

 -23- 

 shall have concluded that there may be legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, such Indemnified Person shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such Proceedings on behalf of such Indemnified Person. Upon
receipt of notice from the Indemnifying Party to such Indemnified Person of its election so to assume the defense of such Proceedings and approval by such Indemnified Person of counsel, the Indemnifying Party shall not be liable to such Indemnified
Person for expenses incurred by such Indemnified Person in connection with the defense thereof (other than reasonable costs of investigation) unless (i) such Indemnified Person shall have employed separate counsel in connection with the
assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the Indemnifying Party shall not be liable for the expenses of more than one separate counsel, approved by Investor,
representing the Indemnified Persons who are parties to such Proceedings), (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to such Indemnified Person to represent such Indemnified Person within a reasonable
time after notice of commencement of the Proceedings or (iii) the Indemnifying Party shall have authorized in writing the employment of counsel for such Indemnified Person. 
 (c) The Indemnifying Party shall not be liable for any settlement of any Proceedings effected without its written consent (which consent shall not be
unreasonably withheld). If any settlement of any Proceeding is consummated with the written consent of the Indemnifying Party or if there is a final judgment for the plaintiff in any such Proceedings, the Indemnifying Party agrees to indemnify and
hold harmless each Indemnified Person from and against any and all losses, claims, damages, liabilities and expenses by reason of such settlement or judgment in accordance with, and subject to the limitations of, the provisions of this
Section 8. Notwithstanding anything in this Section 8 to the contrary, if at any time an Indemnified Person shall have requested the Indemnifying Party to reimburse such Indemnified Person for legal or other expenses in
connection with investigating, responding to or defending any Proceedings as contemplated by this Section 8, the Indemnifying Party shall be liable for any settlement of any Proceedings effected without its written consent if
(i) such settlement is entered into more than (x) 60 days after receipt by the Indemnifying Party of such request for reimbursement and (y) 30 days after receipt by the Indemnified Party of the material terms of such settlement and
(ii) the Indemnifying Party shall not have reimbursed such Indemnified Person in accordance with such request prior to the date of such settlement. The Indemnifying Party shall not, without the prior written consent of an Indemnified Person
(which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened Proceedings in respect of which indemnity has been sought hereunder by such Indemnified Person unless (a) such settlement includes an
unconditional release of such Indemnified Person in form and substance satisfactory to such Indemnified Person from all liability on the claims that are the subject matter of such Proceedings and (b) does not include any statement as to or any
admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. 
 9. Survival of Representations and Warranties, Etc.
Notwithstanding any investigation at any time made by or on behalf of any party hereto, all representations and warranties made in this Agreement will survive the execution and delivery of this Agreement and the Closing Date, except that the
representations and warranties made in Sections 3(i), (n), (p) (q) and (s)-(aa) will only survive for a period of three (3) years after the Closing Date.

 10. Termination. 
 (a) The Investor may terminate this Agreement: 
 (i) On or after June 30, 2006, if the Bankruptcy Court
has not entered the Agreement Order; 
 (ii) On or after October 31, 2006; provided that if the Company notifies the Investor in
writing by 3:00 p.m. New York City time on or before October 24, 2006 that it wishes to extend such date until December 15, 2006, then the Investor may not terminate pursuant to this paragraph (a)(ii) until December 15, 2006,
provided that, as a condition to the effectiveness of such extension, the Company has paid to the Investor not later than 3:00 p.m. New York City time on October 31, 2006, a fee (the “Extension Fee”) in the amount of
$30,000,000, which amount will be paid to the Investor by the Company by wire transfer of immediately available funds; 
 (iii) Upon the
failure of the Company to pay the Extension Fee, if any, when due; 
 (iv) Upon the failure of any of the conditions set forth in
Section 7 hereof to be satisfied, which failure cannot be cured by October 31, 2006 or, if the Extension Fee has been paid, December 15, 2006; or 
 (v) If the Company makes a public announcement, enters into an agreement, or files any pleading or document with the Bankruptcy Court, evidencing its intention to support, or otherwise supports, any Competing
Transaction. 
 (b) Prior to the entry of the Agreement Order, the Company may provide written notice to the Investor of its determination
not to proceed with the transactions contemplated hereby, whereupon this Agreement will terminate. 
 (c) If this Agreement is terminated
pursuant to Section 10(b) and at the time of such termination the Investor is in compliance in all material respects with this Agreement, then, subject to the approval of the Bankruptcy Court, the Company shall pay the Investor
$20,000,000 (the “Termination Fee”), and, in any case, the Company shall pay to the Investor any Transaction Expenses and any other amounts certified by the Investor to be due and payable hereunder that have not been paid
theretofore. Payment of the amounts due under this Section 10(c), will be made by wire transfer of federal (same day) funds to the account specified by the receiving party at least 24 hours in advance to the other party hereto. The
provision for the payment of the Termination Fee is an integral part of the transactions contemplated by this Agreement and without this provision the Investor would not have entered into this Agreement and shall, subject to the approval of the
Bankruptcy Court, constitute an administrative expense of the Company under section 364(c)(1) of the Bankruptcy Code. Accordingly, if payment shall become due and payable pursuant to this Section, and suit is commenced which results in a final
judgment against the Company no longer subject to appeal, the Company shall pay to the Investor its costs and expenses, including attorneys’ fees, in connection with collecting or enforcing its rights and remedies hereunder. 
  

 -25- 

 (d) In no event will the Termination Fee, if any, be refundable upon termination of this Agreement
pursuant to this Section 10. 
 (e) Upon termination under this Section 10, the covenants and agreements made by the
parties herein under Sections 8, 9 and 11 through 18 will survive indefinitely in accordance with their terms. 
 11. Notices.
All notices and other communications in connection with this Agreement will be in writing and will be deemed given (and will be deemed to have been duly given upon receipt) if delivered personally, sent via electronic facsimile (with confirmation),

 12. Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights,
interests or obligations under this Agreement will be assigned by any of the parties (whether by operation of law or otherwise) without the prior written consent of the other party. Notwithstanding the previous sentence, this Agreement, or the

hereto any rights or remedies under this Agreement. 
 13. Prior Negotiations; Entire Agreement. This Agreement (including the agreements attached as
exhibits to and the documents and instruments referred to in this Agreement) constitutes the entire agreement of the parties and supersedes all prior agreements, arrangements or understandings, whether written or oral, between the parties with
respect to the subject matter of this Agreement, except that the parties hereto acknowledge that any confidentiality agreements heretofore executed among the parties will continue in full force and effect. 
 14. GOVERNING LAW; VENUE. THIS AGREEMENT WILL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF DELAWARE. THE INVESTOR HEREBY

the parties and delivered to the other party (including via facsimile or other electronic transmission), it being understood that each party need not sign the same counterpart. 
  

 -27- 

 16. Waivers and Amendments. This Agreement may be amended, modified, superseded, cancelled, renewed or extended,
and the terms and conditions of this Agreement may be waived, only by a written instrument signed by the parties or, in the case of a waiver, by the party waiving compliance, and subject, to the extent required, to the approval of the Bankruptcy
Court. No delay on the part of any party in exercising any right, power or privilege pursuant to this Agreement will operate as a waiver thereof, nor will any waiver on the part of any party of any right, power or privilege pursuant to this
Agreement, nor will any single or partial exercise of any right, power or privilege pursuant to this Agreement, preclude any other or further exercise thereof or the exercise of any other right, power or privilege pursuant to this Agreement. The
rights and remedies provided pursuant to this Agreement are cumulative and are not exclusive of any rights or remedies which any party otherwise may have at law or in equity. 
 17. Headings. The headings in this Agreement are for reference purposes only and will not in any way affect the meaning or interpretation of this Agreement. 
 18. Specific Performance. The parties acknowledge and agree that any breach of the terms of this Agreement would give rise to irreparable harm for which money
damages would not be an adequate remedy, and, accordingly, the parties agree that, in addition to any other remedies, each will be entitled to enforce the terms of this Agreement by a decree of specific performance without the necessity of proving
the inadequacy of money damages as a remedy and without the necessity of posting bond. 
 19. Modifications Necessary to Reflect Corporate
Restructuring. The Amended Plan currently contemplates that, on the Effective Date, the Company intends to effect a restructuring plan which would organize the Company and its subsidiaries along the Company’s major business lines. This
restructuring plan may result in the creation of a new Delaware company to serve as the parent corporation and holding company for the Company and its subsidiaries (“Holdco”). To the extent that such plan to create the Holdco
structure is pursued with the approval of the Bankruptcy Court, the parties hereto shall consider in good faith making appropriate modifications to this Agreement and the Registration Rights Agreement to accommodate the Holdco structure.

 [Signature Page of Equity Commitment Agreement]FORM OF INCENTIVE STOCK OPTION AGREEMENT

 Exhibit 10.1 
 ICAGEN, INC. 
 Incentive Stock Option Agreement 
 Granted Under 2004 Stock Incentive Plan 
  

	1.	Grant of Option. 

 This agreement evidences the
grant by Icagen, Inc., a Delaware corporation (the “Company”), on             , 200[  ] (the “Grant Date”) to
                    , an employee of the Company (the “Participant”), of an option to purchase, in whole or in part, on the
terms provided herein and in the Company’s 2004 Stock Incentive Plan (the “Plan”), a total of              shares (the “Shares”) of common stock,
$0.001 par value per share, of the Company (“Common Stock”) at $             per Share. Unless earlier terminated, this option shall expire at 5:00 p.m., Eastern time, on
                     (the “Final Exercise Date”). 
 It is intended that the option evidenced by this agreement shall be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the
“Code”). Except as otherwise indicated by the context, the term “Participant”, as used in this option, shall be deemed to include any person who acquires the right to exercise this option validly under its terms. 
  

	2.	Vesting Schedule. 

 This option becomes exercisable
(“vest”) as to              shares [total number of shares divided by 48] for each full month of continuous employment with the Company beginning
                    . 
 The right
of exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in part, with respect to all Shares for which it is vested until the
earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the Plan. 
  

	3.	Exercise of Option. 

 (a) Form of Exercise.
Each election to exercise this option shall be in writing, signed by the Participant, and received by the Company at its principal office, accompanied by this agreement, and payment in full as follows: 
 (1) in cash or by check, payable to the order of the Company; 
 (2) by (i) delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient
funds to pay the exercise price and any required tax withholding or (ii) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly 

 
to the Company cash or a check sufficient to pay the exercise price and any required tax withholding; 
 (3) with the approval of the Board, when the Common Stock is registered under the Exchange Act, by delivery of shares of Common Stock
owned by the Participant valued at their fair market value as determined by (or in a manner approved by) the Board in good faith (“Fair Market Value”), provided (i) such method of payment is then permitted under applicable law and (ii)
such Common Stock, if acquired directly from the Company, was owned by the Participant at least six months prior to such delivery; 
 (4) to the extent permitted by applicable law and by the Board, in its sole discretion by (i) delivery of a promissory note of the Participant to the Company on terms determined by the Board, or (ii) payment of such other lawful
consideration as the Board may determine; or 
 (5) by any combination of the above permitted forms of payment. 
 The Participant may purchase less than the number of shares covered hereby, provided that no partial exercise of this option may be for any fractional share. 

(b) Continuous Relationship with the Company Required. Except as otherwise provided in this Section 3, this option may not be exercised unless
the Participant, at the time he or she exercises this option, is, and has been at all times since the Grant Date, an employee or officer of, or consultant or advisor to, the Company or any parent or subsidiary of the Company as defined in Section
424(e) or (f) of the Code (an “Eligible Participant”). 
 (c) Termination of Relationship with the Company. If the
Participant ceases to be an Eligible Participant for any reason, then, except as provided in paragraphs (d) and (e) below, the right to exercise this option shall terminate three months after such cessation (but in no event after the Final Exercise
Date), provided that this option shall be exercisable only to the extent that the Participant was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if the Participant, prior to the Final
Exercise Date, violates the non-competition or confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Participant and the Company, the right to exercise this option shall
terminate immediately upon such violation. 
 (d) Exercise Period Upon Death or Disability. If the Participant dies or becomes
disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant and the Company has not terminated such relationship for “cause” as specified in paragraph (e) below,
this option shall be exercisable, within the period of one year following the date of death or disability of the Participant, by the Participant (or in the case of death by an authorized transferee), provided that this option shall be
exercisable only to the extent that this option was exercisable by the Participant on the date of his or her death or disability, and further provided that this option shall not be exercisable after the Final Exercise Date. 
  

 - 2 - 

 (e) Discharge for Cause. If the Participant, prior to the Final Exercise Date, is discharged by
the Company for “cause” (as defined below), the right to exercise this option shall terminate immediately upon the effective date of such discharge. “Cause” shall mean willful misconduct by the Participant or willful failure by
the Participant to perform his or her responsibilities to the Company (including, without limitation, breach by the Participant of any provision of any employment, consulting, advisory, nondisclosure, non-competition or other similar agreement
between the Participant and the Company), as determined by the Company, which determination shall be conclusive. The Participant shall be considered to have been discharged for “Cause” if the Company determines, within 30 days after the
Participant’s resignation, that discharge for cause was warranted. 
  

	4.	Agreement in Connection with Public Offering. 

 The
Participant agrees, in connection with an underwritten public offering of the Company’s securities pursuant to a registration statement under the Securities Act, (i) not to sell, make short sale of, loan, grant any options for the purchase of,
or otherwise dispose of any shares of Common Stock held by the Participant (other than those shares included in the offering) without the prior written consent of the Company or the underwriters managing such initial underwritten public offering of
the Company’s securities for such number of days (not to exceed 180 days) from the effective date of such registration statement as the managing underwriters or the Company may require, and (ii) to execute any agreement reflecting clause (i)
above as may be requested by the Company or the managing underwriters at the time of such offering. 
  

	5.	Tax Matters. 

 (a) Withholding. No Shares
will be issued pursuant to the exercise of this option unless and until the Participant pays to the Company, or makes provision satisfactory to the Company for payment of, any federal, state or local withholding taxes required by law to be withheld
in respect of this option. When the Common Stock is registered under the Exchange Act, Participant may satisfy such tax obligations in whole or in part by delivery of shares of Common Stock owned by Participant; provided, however, that the total tax
withholding where stock is being used to satisfy such tax obligations cannot exceed the Company’s minimum statutory withholding obligations (based on minimum statutory withholding rates for federal and state tax purposes, including payroll
taxes, that are applicable to such supplemental taxable income). The Company may, to the extent permitted by law, deduct any such tax obligations from any payment of any kind otherwise due to Participant. 
 (b) Disqualifying Disposition. If the Participant disposes of Shares acquired upon exercise of this option within two years from the Grant Date or
one year after such Shares were acquired pursuant to exercise of this option, the Participant shall notify the Company in writing of such disposition. 
  

	6.	Nontransferability of Option. 

 This option may not
be sold, assigned, transferred, pledged or otherwise encumbered by the Participant, either voluntarily or by operation of law, except by will or the laws of descent 

  

 - 3 - 

 
and distribution, and, during the lifetime of the Participant, this option shall be exercisable only by the Participant. 
  

	7.	Provisions of the Plan. 

 This option is subject to
the provisions of the Plan, a copy of which is furnished to the Participant with this option. 
 IN WITNESS WHEREOF, the Company has caused
this option to be executed under its corporate seal by its duly authorized officer. This option shall take effect as a sealed instrument.
