 A G R E E M E N T 
 NOW, THEREFORE, in
consideration of the mutual promises, representations, warranties, covenants and conditions set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto mutually
agree as follows: 
 1. RESTRICTIONS ON TRANSFER. 
 1.1 Restrictions. Each of the Common Stockholders, the Series E Stockholders, and the Series F Stockholders (each individually, a “Stockholder” and collectively, the “Stockholders”) agrees that, during the term of
this Agreement, all shares of capital stock of the Company (collectively, the “Shares”) now or hereafter owned by such Stockholders shall be subject to the terms and conditions of this Agreement; provided, however, that “Shares”
shall not include any shares of Common Stock or Series E Preferred Stock owned by a Stockholder as a result of such Stockholder’s exercise of an option granted pursuant to the Company’s 2000 Stock Option and Restricted Stock Plan, as
amended (the “2000 Option Plan”) and any shares of capital stock of the Company issued on or in respect of any such excluded Common Stock or Series E Preferred Stock, except as otherwise set forth in the agreement or agreements thereunder
with respect to such option exercises. No Stockholder shall Transfer any Shares, either voluntarily or involuntarily, except as permitted by, and in compliance with, the provisions of this Agreement, and any attempted Transfer which is not permitted
by, and which is not in compliance with, the provisions of this Agreement shall be void and ineffective for all purposes. For purposes of this Agreement, (a) “Transfer” shall mean any direct or indirect transfer, sale, assignment,
exchange, mortgage, pledge, hypothecation or other disposition of any Shares, and (b) any person to whom Shares have been Transferred, directly or indirectly, is sometimes individually referred to hereinafter as a “Transferee.”

 1.2 Permitted Transfers of Common Stock. A Stockholder shall be permitted to Transfer all or any Shares of Common Stock as follows:

 (a) a Transfer to the Company; 
 (b) a Transfer by (i) a partnership to its partners or former partners in accordance with partnership interests, (ii) a
corporation to its shareholders in accordance with their interest in the corporation, (iii) a limited liability company to its members or former members in accordance with their interest in the limited liability company, or (iv) an
individual Stockholder to such Stockholder’s spouse or issue or trust for the benefit of such Stockholder or such Stockholder’s spouse or issue; provided, that in each case the Transferee agrees to be subject to the terms of this Agreement
to the same extent as if the Transferee were an original Stockholder hereunder; 
  

 2 

 (c) a Transfer to a third party when there is then in effect a registration statement
under the Securities Act of 1933, as amended (the “Securities Act”) covering a proposed sale of the Shares and such sale is made in accordance with such registration statement; or 
 (d) a Transfer in connection with a merger or share exchange which is approved by the Company and its stockholders in accordance with the
Delaware General Corporation Law and the Company’s Eighth Amended and Restated Certificate of Incorporation, as it may be amended (for purposes hereof, such transaction is referred to herein as an “Approved Share Transaction”); or

 (e) a Transfer which is otherwise permitted under the terms of this Agreement. 
 1.3 Permitted Transfers of Preferred Stock. A Stockholder shall be permitted to Transfer all or any Shares of Preferred Stock as follows:

 (a) a Transfer to a third party when there is then in effect a registration statement under the Securities Act covering a
proposed sale of the Shares and such sale is made in accordance with such registration statement; 
 (b) a Transfer when
(i) the Transferee has agreed in writing to be bound by the terms of this Agreement, (ii) such Stockholder shall have notified the Company of the proposed Transfer and shall have furnished the Company with a detailed statement of the
circumstances surrounding the proposed Transfer, and (iii) if reasonably requested by the Company, such Stockholder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such Transfer will not
require registration of such Shares under the Securities Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 of the Securities Act (“Rule 144”); or 
 (c) a Transfer in connection with an Approved Share Transaction; or 
 (d) a Transfer which is otherwise permitted under the terms of this Agreement. 
 Notwithstanding the provisions of Sections 1.3(a) and (b), above, no such registration statement or opinion of counsel shall be necessary for a Transfer by a Stockholder
(i) which is a partnership to its partners or former partners in accordance with partnership interests, (ii) which is a corporation to its shareholders in accordance with their interest in the corporation or to any Affiliate of such
corporation, (iii) which is a limited liability company to its members or former members in accordance with their interest in the limited liability company, (iv) to the Stockholder’s family member or trust for the benefit of an
individual Stockholder, or (v) to an Affiliate of such Stockholder who or which would have been eligible to participate in the offering of the Shares as originally acquired from the Company; provided that in each case the Transferee will be
subject to the terms of this Agreement to the same extent as if he were an original Stockholder hereunder. For purposes hereof, “Affiliate” shall mean an (i) entity controlling, controlled by or under common control with a
Stockholder, and (ii) the partners, members or shareholders of a Stockholder. 
  

 3 

 1.4 Certain Marital Transfers. Anything contained in this Agreement to the contrary
notwithstanding, the creation or existence of any interest in any Shares which interest is acquired or owned by the spouse or former spouse of any Stockholder as community or marital property during marriage, as a result of property division or
other award or Transfer upon dissolution of the marriage, or as a result of any allowance or assignment of property under any applicable community or marital property law (a “Marital Transfer”) shall be permitted by, and deemed in
compliance with, this Agreement; provided, however, that the following conditions are satisfied: (a) the Shares in which such an interest is created or exists are and continue to be (i) held of record in the name of such Stockholder, and
(ii) managed and controlled by such Stockholder, and (b) the spouse or former spouse shall have executed a Spousal Consent and Acknowledgement in the form attached hereto as Exhibit D. At the first such time when either of the
conditions in the foregoing provision cease to be satisfied with respect to any Shares (a “Prohibited Marital Transfer”), an Offer of Sale (as hereinafter defined) shall be deemed to have been given with respect to such Shares. 

2. RIGHT OF FIRST REFUSAL. 
 2.1 Offer of Sale before
Transfer. If a Stockholder at any time proposes to make, or is to suffer, any Transfer of any Shares of Common Stock (or, in the case of a Prohibited Marital Transfer, Preferred Stock) to one or more persons (collectively, an “Unrelated
Transferee”) and such Transfer is not permitted pursuant to Section 1 hereof (the “Subject Transfer”), such Stockholder (the “Transferor”) shall first offer to sell such Shares to the Company by written notice given to
the Company. Such notice (the “Offer of Sale”) shall describe in reasonable detail the Subject Transfer, including the number (and type, in case of a Prohibited Marital Transfer) of Shares to be subject to the Subject Transfer (the
“Offered Shares”), the identity of the person(s) who are the Unrelated Transferee, the nature of the Subject Transfer, the form and amount of consideration per Offered Share to be received by the Transferor pursuant to the Subject Transfer
(the “Transfer Price”), the terms of payment of such consideration, and the date on which the Subject Transfer is to occur. Upon request, the Transferor also shall provide to the Company copies of all documents which the Transferor will be
required to execute in connection with the Transfer and such additional information about the transactions as may be reasonably requested. However, in the case of any deemed Offer of Sale resulting from a Prohibited Marital Transfer, the Offered
Shares shall be deemed to be offered first to the Stockholder whose Shares were subject to the Prohibited Marital Transfer (the “Marital Party”) and then to the Company and, notwithstanding that an Offer of Sale shall be deemed to have
been given upon such Prohibited Marital Transfer, the Transferor shall give written notice setting forth the information described above as that to be specified in an Offer of Sale with respect to such Prohibited Marital Transfer to the Company (the
“Deemed Offer of Sale Notice”) as promptly as practicable after the Prohibited Marital Transfer. For purposes hereof, the Offered Shares shall be deemed to be offered to the Company, or first to the Marital Party and then to the Company,
as the case may be, at a purchase price per share equal to the Transfer Price specified in the Offer of Sale or the Deemed Offer of Sale Notice, as the case may be; provided, however, that if the Transfer Price specified in the Offer of Sale or the
Deemed Offer of Sale Notice, as the case may be, includes consideration which is not payable in money, or if the Subject Transfer is to be made for consideration based upon future earnings or other amounts indeterminable at the time the Offer of
Sale or the Deemed Offer of Sale Notice is given, as the case may be, then the Transfer Price shall be deemed to be the amount per share which is reasonably equivalent to the cash value per 

  

 4 

 
share of such consideration (the “Cash Equivalent Value”) or, if the Subject Transfer is a gift or is not in the nature of a sale or other
disposition in exchange for consideration, then the Transfer Price shall be deemed to be equal to the amount per Share which is estimated to be the fair value per Share (the “Estimated Value”) as of the date on which the Offer of Sale is
given or is deemed to have been given, as the case may be. For purposes hereof, the “Cash Equivalent Value” or the “Estimated Value” shall be the amount determined by the agreement of the parties to each transaction, or if, on
the thirtieth (30th) day after the date on which the Offer of Sale is given or is deemed to have been given, no such agreement exists, by the Board of Directors of the Company acting in good faith. 
 2.2 Acceptance of Offer of Sale. The Company may accept the Offer of Sale by giving an Acceptance Notice (as hereinafter defined) to the
Transferor at any time within the ninety (90) day period commencing on the date on which the Offer of Sale is given or is deemed to have been given; provided, however, that, in the case of any Offer of Sale deemed to have been given as a result
of a Prohibited Marital Transfer, the Marital Party may accept the Offer of Sale by giving an Acceptance Notice to the Transferor within the first sixty (60) days of such ninety (90) day period. If the Marital Party does not accept the
Offer of Sale within such sixty (60) day period as to all of the Offered Shares, then the Company may so accept the Offer of Sale during the remaining thirty (30) days of such ninety (90) day period. For purposes hereof, an
“Acceptance Notice” shall mean a written notice which specifies the number of the Offered Shares as to which the Company or the Marital Party, as the case may be, desires to accept in an Offer of Sale. 
 2.3 Effect of Acceptance Notices. Subject to Section 2.4 hereof, upon the acceptance of the Offer of Sale by the Company or the Marital
Party, as the case may be, in accordance with Section 2.2 hereof, the Transferor shall be required to sell, and the Company or the Marital Party, as the case may be, shall be required to purchase, all of the Offered Shares with respect to which
the Company or the Marital Party, as the case may be, has accepted the Offer of Sale at the price and upon the terms and conditions for closing and payment which are specified herein. 
 2.4 Transfer Permitted. Notwithstanding the foregoing, if the Company and the Marital Party do not accept the Offer of Sale with respect to, and
purchase, all (and not less than all) of the Offered Shares as contemplated above, then the Transferor may, within the sixty (60) day period commencing on the expiration of the ninety (90) day period during which the Offer of Sale may be
accepted pursuant to Section 2.2 hereof, Transfer the Offered Shares to the Unrelated Transferee at a price not less than the Transfer Price, payable pursuant to terms and conditions which are no more favorable to the Unrelated Transferee than
those specified in the Offer of Sale, subject to the right of the Stockholders pursuant to Section 3, below. In such event, the Shares Transferred will no longer be subject to, and the holder thereof will no longer be bound by or receive the
benefit of, the terms of this Agreement. 
 2.5 Closing and Certain Other Terms. The closing of any sale of Shares pursuant to this
Section 2 and the terms and conditions pursuant to which the purchase price in any such sale shall be payable shall be as follows: 
 (a) The consummation of the sale of Shares shall occur at the Company’s principal office on the day (or on the next succeeding business day) which is the later of the 

  

 5 

 
fifteenth (15th) day after the date on which the Cash Equivalent Value or Estimated Value for purposes of such sale is determined in accordance with
Section 2.1 hereof or the thirtieth (30th) day after the date on which the Offer of Sale has been accepted with respect to all of the Offered Shares. 
 (b) Except in the case of a Prohibited Marital Transfer or a Transfer by gift, the purchase price for the Shares shall be paid on the same
terms and conditions for payment which have been offered by the Unrelated Transferee, as indicated in the Offer of Sale. Otherwise, the purchase price shall be payable in cash at the closing. 
 (c) At the closing, each person selling Shares shall deliver to the Company or the Marital Party, as the case may be, the certificate(s)
evidencing ownership of the Shares subject to such sale, properly endorsed or accompanied by properly executed stock powers and all such instruments or documents as shall reasonably be required by the Company or the Marital Party, as the case may
be, in connection with such Transfer of such Shares, and such Shares shall be delivered free and clear of all liens, claims, encumbrances and restrictions other than those imposed under this Agreement. At the closing, the Company or the Marital
Party, as the case may be, shall deliver to each person from whom such Shares are being purchased, payment of the purchase price therefor as provided above. 
 3. CO-SALE RIGHTS. 
 3.1 Definition of Third Party Sale. For purposes hereof, a “Third Party Sale” shall mean
either (i) any proposed Transfer of Shares with respect to which (A) the provisions of Section 2, above, apply and (B) neither the Company nor the Marital Party shall have accepted the Offer for Sale under Sections 2.1 through
2.3, above, within the applicable time periods set forth therein, or (ii) any other proposed Transfer of Shares by one or more Stockholders, which is not permitted under Sections 1.2 or 1.3, above. 
 3.2 Election to Participate in Third Party Sale. If one or more Stockholders (collectively, a “Proposing Stockholder”) shall at any time
propose to effect a Third Party Sale, then the Proposing Stockholder shall give written notice of the proposed Third Party Sale (the “Third Party Notice”) to each of the other Stockholders (the “Non-Proposing Stockholders”). The
Third Party Notice shall set forth the number and type of Shares to be Transferred (the “Transferred Shares”) in the Third Party Sale, the name and address of the proposed transferee (the “Proposed Transferee”) and the terms and
conditions (including the sale price) of the proposed Third Party Sale. Upon receipt of the Third Party Notice, each of the Non-Proposing Stockholders shall have the right (the “Co-Sale Right”) to sell in the contemplated Third Party Sale,
at the same price and on the same terms and conditions as are set forth in the Third Party Notice, (i) that number of Shares which are Common Stock owned by such Non-Proposing Stockholder and/or that number of Shares which are Preferred Stock
owned by such Non-Proposing Stockholder which, as of the date of the closing of the Third Party Sale, would be convertible into Shares which are Common Stock collectively representing the same percentage as is equal to the percentage which the
Transferred Shares which are Common Stock represent of the total number of Shares of Common Stock owned by the Proposing Stockholder and (ii) that percentage of Shares which are of a given series of the Preferred Stock owned by such
Non-Proposing Stockholder as is equal to the percentage which the Transferred Shares which are 

  

 6 

 
of the same series of the Preferred Stock represent of the total number of Shares of such series of Preferred Stock owned by the Proposing Stockholder, as
the case may be. Within sixty (60) days after the Third Party Notice is given to the Non-Proposing Stockholders, each Non-Proposing Stockholder shall notify the Proposing Stockholder in writing whether such Non-Proposing Stockholder elects to
participate in the Third Party Sale, and, if so, the number and type of Shares that each of them wishes to sell (which number may not exceed the number described in the previous sentence); provided, however, that if the Proposed Transferee objects
to the delivery of Series E Preferred Stock or Series F Preferred Stock in lieu of Common Stock as contemplated by clause (i) of the preceding sentence or in addition to Common Stock as contemplated by clause (ii) of the preceding
sentence, such Non-Proposing Stockholder shall convert such Series E Preferred Stock, or Series F Preferred Stock into Common Stock and deliver Common Stock; provided, however, that, as to Preferred Stock to be transferred in addition to Common
Stock, such Preferred Stock shall be so converted to the same extent (i.e., in the same percentage for each given series) as are the Transferred Shares which are Preferred Stock (a “Conversion”). The Company agrees to make any such
Conversion concurrent with the actual transfer of such Shares to the Proposed Transferee and contingent on such transfer. If a Non-Proposing Stockholder does not respond in writing within said sixty (60) day period, the Non-Proposing
Stockholder shall conclusively be deemed to have elected not to participate in the Third Party Sale. If a Non-Proposing Stockholder timely responds in writing within such sixty (60) day period, such Non-Proposing Stockholder will be irrevocably
bound to consummate the proposed Third Party Sale with respect to the number and type of Shares as is indicated in the written response given by such Non-Proposing Stockholder, unless thereafter relieved of such obligation in writing by the
Proposing Stockholder or unless the Proposing Stockholder has not completed the contemplated Third Party Sale within one hundred eighty (180) days after the Third Party Notice. In the event the Proposing Stockholder has not completed a Third
Party Sale within such one hundred eighty (180) day period, then the provisions of this Section 3.2 shall continue to apply to any subsequent Third Party Sale. 
 3.3 Other Co-Sale Right Terms. If the Co-Sale Right is exercised as provided herein, each Non-Proposing Stockholder must undertake any and all actions reasonably requested to effect the Third Party Sale
including, without limitation, (a) exercising voting rights in favor of the Third Party Sale, (b) delivering to the Proposing Stockholder for transfer to the Transferee one or more certificates, properly endorsed for transfer, which
represent that number of Shares which such Non-Proposing Stockholder elects to sell, and (c) executing any purchase or sale agreement and related agreements with respect to the transaction and making substantially the same representations,
warranties, covenants and indemnities and similar agreements as the Proposing Stockholder agrees to make. Anything contained herein to the contrary notwithstanding, no such Non-Proposing Stockholder shall be required to incur any liability or make
any representation, warranty, covenant or indemnity unless the Proposing Stockholder is required to incur substantially the same economic liability on a pro rata (or greater) basis and make substantially the same representation, warranty, covenant
or indemnity on a pro rata (or greater) basis. 
 3.4 Co-Sale Proceeds. Concurrently with the delivery by a Non-Proposing Stockholder
of certificates to the Proposing Stockholder pursuant to Section 3.3, above, the Proposing Stockholder shall remit to such Non-Proposing Stockholder that portion of the Third Party Sale proceeds to which such Non-Proposing Stockholder is
entitled by reason of its 

  

 7 

 
participation in such Third Party Sale. To the extent that any Transferee prohibits such assignment or otherwise refuses to purchase Shares from a
Non-Proposing Stockholder exercising its Co-Sale Right hereunder, the Proposing Stockholder shall not sell to such Transferee any Shares unless and until, simultaneously with such sale, the Transferee shall purchase such Shares from such
Non-Proposing Stockholder on the same terms and conditions specified in the Third Party Notice. 
 4. RIGHTS OF FIRST REFUSAL ON COMPANY ISSUANCES OF STOCK.

 4.1 Subsequent Offerings. Each Stockholder shall have a right of first refusal to purchase a number of shares of all Equity
Securities (as hereinafter defined) that the Company may, from time to time, propose to sell and issue after the date of this Agreement, other than the Equity Securities excluded by Section 4.4 hereof and Equity Securities which may be
purchased by Schott AG, a German corporation (“Schott”), under Section 4.5 hereof, up to such Stockholder’s pro rata share of all such Equity Securities. Each Stockholder’s pro rata share is equal to the ratio of
(a) the number of Shares of Common Stock (including all shares of Common Stock issued or issuable upon conversion of the Series E Preferred Stock and Series F Preferred Stock) which such Stockholder holds immediately prior to the issuance of
such Equity Securities to (b) the total number of Shares of Common Stock (including all shares of Common Stock issued or issuable upon conversion of the Series E Preferred Stock and Series F Preferred Stock or upon the exercise of any
outstanding warrants or options) immediately prior to the issuance of the Equity Securities held by all Stockholders; provided, however, that to the extent that Schott exercises its right under Section 4.5 to purchase a portion of the Equity
Securities, which is greater than the portion it could purchase under this Section 4.1, the number of shares of Equity Securities which each other Stockholder may purchase under this Section 4.1 shall be proportionately reduced to give
effect to the issuance of any Equity Securities purchased by Schott under Section 4.5 hereof. The term “Equity Securities” shall mean (a) any Common Stock, Series E Preferred Stock, Series F Preferred Stock or other equity
security of the Company, (b) any security convertible, with or without consideration, into any Common Stock, Series E Preferred Stock, Series F Preferred Stock or other equity security of the Company (including any option to purchase such a
convertible security), (c) any security carrying any warrant or right to subscribe to or purchase any Common Stock, Series E Preferred Stock, Series F Preferred Stock or other equity security of the Company, or (d) any such warrant or
right. 
 4.2 Exercise of Rights. If the Company proposes to issue any Equity Securities, it shall give each Stockholder written
notice of its bona fide intention, describing the Equity Securities, the price and the terms and conditions upon which the Company proposes to issue the same. Each Stockholder shall have twenty (20) days from the receipt of such notice to agree
to purchase its pro rata share of the Equity Securities for the price and upon the terms and conditions specified in the notice by giving written notice to the Company and stating therein the quantity of Equity Securities to be purchased. The
Company may not offer such Equity Securities to other investors on terms more favorable to such other investors than the terms offered to the Stockholders during the period of sixty (60) days from the commitment of the Stockholders to invest in
the Company pursuant to this Section 4. Notwithstanding the foregoing, the Company shall not be required to offer or sell such Equity Securities to any Stockholder who would cause the Company to be in violation of applicable federal securities
laws by virtue of such offer or sale. 
  

 8 

 4.3 Transfer of Rights of First Refusal. The rights of first refusal established by this
Section 4 may be transferred to a Transferee permitted under paragraph (b) of Section 1.2, above, or paragraph (b) of Section 1.3, above, in connection with a transfer of at least fifty thousand (50,000) shares (as
adjusted for stock splits and combinations) of Common Stock (including all shares of Common Stock issued or issuable upon conversion of the Series E Preferred Stock and the Series F Preferred Stock). 
 4.4 Excluded Securities. The rights of first refusal established by this Section 4 shall have no application to any of the following Equity
Securities (collectively, “Excluded Securities”): 
 (a) shares of Common Stock (and/or options, warrants or other
