REPRESENTATIONS AND WARRANTIES 

3.1 Representations and Warranties of the Company. The Company hereby represents and warrants to the Investors as of the date hereof

(a) Subsidiaries. The Company has no subsidiaries other than those listed on Schedule 3.1(a) hereto and
the Company does not own or have any right or obligation (by law, contract or otherwise) to make any investment or otherwise acquire, directly or indirectly, any outstanding capital stock of, or other equity interest in, any Person. The Company

(b) Organization and Qualification. Each of the Company and the Company Subsidiaries is an entity duly organized,
validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization (except, in the case of good standing, for entities organized under the laws of any jurisdiction that does not recognize such concept),
with the requisite corporate power and authority to own and use its properties and assets and to carry on its business as currently conducted. The Company has made available to the Investors a true and correct copy of the Company Charter Documents
and Subsidiary Charter Documents, and each such instrument is in full force and effect. Neither the Company nor any Company Subsidiary is in violation of any of the provisions of its Company Charter Documents or Subsidiary Charter Documents, as the
case may be. The Company and the Company Subsidiaries are duly qualified to do business and are in good standing (except for entities organized under the laws of any jurisdiction that does not recognize such a concept) as a foreign corporation or
other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, would not have or
reasonably be expected to result in a Material Adverse Effect. 
 (c) Authorization; Enforcement. 

(i) The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated
by each of the Transaction Documents to which it is a party and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of each of the Transaction Documents to which it is a party by the Company and the
consummation by it of the transactions contemplated hereby and thereby have

of the Transaction Documents to which it is a party has been (or upon delivery will be) duly executed by the Company and is, or when delivered in accordance with the terms hereof, will constitute, the valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as may be limited by (A) applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting the enforcement of creditors rights
generally, and (B) the effect of rules of law governing the availability of specific performance and other equitable remedies. 

(ii) At meetings duly called and held of the Company Board and a duly constituted special committee of the Company Board (the
“Special Committee”), prior to the execution of this Agreement, at which all directors of the Company or committee members, as the case may be, except as set forth on Schedule 3.1 (c), were present and voting in favor,

business combination and stockholder vote requirements contained in Section 203 of the DGCL will not apply with respect to or as a result of the Transaction Documents and the transactions contemplated hereby and thereby. No other “control
share acquisition,” “fair price,” “moratorium” or other anti-takeover law applies to the Transaction Documents and the transactions contemplated hereby and thereby. 

(d) No Conflicts; Required Filings and Consents.

consummation by the Company of the transactions contemplated hereby and thereby do not, and will not, (A) conflict with or violate any provision of the Company Charter Documents or Subsidiary Charter Documents, (B) result in any breach of,

obligations of any third party under, give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, or result in the creation of a Lien on any of the properties or assets of the

material insurance policies of the Company and the Company Subsidiaries are in full force and effect, no notice of cancellation has been received with respect thereto, there is no existing default or event which, with the giving of notice or lapse

such coverage expires as may be necessary to continue its business without a significant increase in cost.

control over financial reporting (as such term is defined in Rule 13a-15 of the General Rules and Regulations under the Exchange Act) to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial

afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Common Shares and the merits and risks of
investing in the Common Shares, and (ii) access to information about the Company and the Company Subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient to enable
it to evaluate its investment. Neither such inquiries nor any other investigation conducted by or on behalf of such Investor or its representatives or counsel shall modify, amend or affect such Investor’s right to rely on the truth, accuracy
and completeness of the Disclosure Materials and the Company’s representations and warranties contained in the Transaction Documents. 

(f) No Governmental Review. Such Investor understands that no United States federal or state agency or any other
government or governmental agency has passed on or made any recommendation or endorsement of the Common Shares or the fairness or suitability of the investment in the Common Shares nor have such authorities passed upon or endorsed the merits of the
offering of the Common Shares. 
 (g) No Conflicts. The execution, delivery and performance by such Investor of this
Agreement and the consummation by such Investor of the transactions contemplated hereby will not (i) result in a violation of the organizational documents of such Investor or (ii) conflict with, or constitute a default (or an event which
with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any Contract to which such Investor is a party, or (iii) result in a violation of any
Legal Requirements (including federal and state securities laws) applicable to such Investor, except in the case of clauses (ii) and (iii) above, for such violations that do not otherwise affect the ability of Investors to consummate the
transactions contemplated hereby. 
 (h) Restricted Securities. Such Investor understands that the Common Shares are
characterized as “restricted securities” under the U.S. federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such
securities may be resold without registration under the Securities Act only in certain limited circumstances. 

  
 22 








 (i) Availability of Funds. On the Closing Date, such Investor will have
immediately available funds in cash that will be sufficient to fulfill its obligations under Article II. 
 (j)
Brokers or Finders. There is no investment banker, broker, finder or other intermediary that has been retained by, or is authorized to act on behalf of, such Investor or any of its Affiliates, or any of their respective officers or directors
in their capacity as officers or directors, who might be entitled to any banking, broker’s, finder’s or similar fee or commission in connection with the transactions contemplated by this Agreement. 

(k) Prohibited Transactions. Such Investor does not own, directly or indirectly, and no Person acting on behalf of or
pursuant to any understanding with such Investor owns, any securities, including any derivatives, of the Company. Such Investor covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with such Investor will
engage, directly or indirectly, in any Short Sales involving the Company’s securities. “Short Sales” include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the
Exchange Act and all types of direct and indirect stock pledges, forward sale contracts, options, puts, calls, short sales, swaps, derivatives and similar arrangements (including on a total return basis), and sales and other transactions through
non-U.S. broker-dealers or foreign regulated brokers. 
 ARTICLE IV 

ADDITIONAL AGREEMENTS 
 4.1
Transfer Restrictions. 
 (a) Each Investor severally covenants that the Common Shares will only be disposed of
pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act, and in compliance with any
applicable state securities laws. Notwithstanding the foregoing, the Company hereby consents to and agrees to register on the books of the Company and with its Transfer Agent any transfer of the Common Shares by an Investor to an Affiliate of such
Investor, provided that the transferee certifies to the Company that it is an “accredited investor” as defined in Rule 501(a) under the Securities Act and provided that such Affiliate does not request any removal of any existing
legends on any certificate evidencing the Common Shares. 
 (b) The Investors agree that the following legend shall be
imprinted on any certificate evidencing any of the Common Shares: 
 THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE
SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY APPLICABLE STATE SECURITIES LAWS AND,
ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN 

  
 23 








 
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND
IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS. 
 In addition, if any Investor is an Affiliate of the
Company, certificates evidencing the Common Shares issued to such Investor shall bear a customary “affiliates” legend. 

The legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of the
Common Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account of The Depository Trust Company, if, unless otherwise required by state securities laws, (i) such Common Shares are
registered for resale under the Securities Act, (ii) in connection with a sale, assignment or other transfer, such holder provides the Company with an opinion of counsel, the form and substance of which opinion shall be reasonably acceptable to
the Company, that the sale, assignment or transfer of the Common Shares may be made without registration under the applicable requirements of the Securities Act or (iii) such holder provides the Company with reasonable assurance that the Common
Shares can be sold, assigned or transferred pursuant to Rule 144 of the Securities Act (if the transferor is not an Affiliate of the Company) or have been sold under Rule 144. 

4.2 Furnishing of Information. Until the date that all of the Investors owning Common Shares sell all of the Common Shares, the Company
shall use its best efforts to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. The Company further
covenants that it will take such further action as any holder of Common Shares may reasonably request to satisfy the provisions of this Section 4.2. 

4.3 Integration. The Company shall not, and shall use its commercially reasonably efforts to ensure that no Affiliate thereof shall,
sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Common Shares in a manner that would require
the registration under the Securities Act of the sale of the Common Shares to the Investors or that would be integrated with the offer or sale of the Common Shares for purposes of the rules and regulations of any Trading Market. 

4.4 Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Common Shares as required under Regulation
D and to provide a copy thereof, promptly upon request of any of the Investors. The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Common Shares for, sale
to the Investors at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of the Investors. 

4.5 Public Disclosure. Without limiting any other provision of this Agreement, the Investors and the Company will consult with each
other before issuing, and provide each other 

  
 24 








 
the reasonable opportunity to review and comment upon, and agree on, any press release with respect to this Agreement and the transactions contemplated hereby and will not issue any such press
release prior to such review, except as may be required by law or any listing agreement with or rule of any applicable national or regional securities exchange or market. 

4.6 Acknowledgement. Each Investor hereunder acknowledges its primary responsibilities under the Securities Act and accordingly will
not sell or otherwise transfer the Common Shares or any interest therein without complying with the requirements of the Securities Act. While a registration statement relating to the Common Shares remains effective, each Investor hereunder may sell
the Common Shares in accordance with the plan of distribution contained in the registration statement (if it is selling such securities pursuant to the registration statement) and, if it does so, it will comply therewith and with the related
prospectus delivery requirements unless an exemption therefrom is available. Each Investor, severally and not jointly with the other Investors, agrees that if it is notified by the Company in writing at any time that such registration statement
registering the resale of the Common Shares is not effective or that the prospectus included in such registration statement no longer complies with the requirements of Section 10 of the Securities Act, the Investor will refrain from selling
such Common Shares until such time as the Investor is notified by the Company that such registration statement is effective or such prospectus is compliant with Section 10 of the Exchange Act, unless such Investor is able to, and does, sell
such Common Shares pursuant to an available exemption from the registration requirements of Section 5 of the Securities Act. 
 4.7
Commercially Reasonable Efforts. Upon the terms and subject to the conditions set forth in this Agreement, each of the Investors and the Company shall use commercially reasonable efforts to take, or cause to be taken, all actions, and to do,
or cause to be done, and to assist and cooperate with the other party or parties hereto in doing, all things reasonably necessary, proper or advisable under applicable Legal Requirements to consummate and make effective, in the most expeditious
manner practicable, the transactions contemplated by this Agreement, including using commercially reasonable efforts to: (i) cause the conditions to the issuance of the Common Shares pursuant to this Agreement set forth in Article V to be
satisfied; (ii) obtain all necessary actions or non-actions, waivers, consents, approvals, orders and authorizations from Governmental Entities and make all necessary registrations, declarations and filings with Governmental Entities; and
(iii) execute or deliver any additional instruments reasonably necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement. The Company and the Investors shall cooperate with one another
(x) in determining whether any action by or in respect of, or filing with, any Governmental Entity is required, or any actions, consents, approvals or waivers are required to be obtained from parties to any material Contracts, in connection
with the consummation of the transactions contemplated by this Agreement and (y) in taking such reasonable actions or making any such filings, furnishing information required in connection therewith and seeking timely to obtain any such
actions, consents, approvals or waivers. 
 4.8 Use of Proceeds. The Company shall use the net proceeds from the sale of the Common
Shares for general working capital purposes. 
 4.9 Listing of Common Stock. Throughout the period during which any Registration
Statement required by Article VI hereof is effective, the Company will not voluntarily terminate 

  
 25 








 
its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would permit such termination. The Company hereby agrees
to use commercially reasonable efforts to maintain the listing of its Common Stock on the Nasdaq Capital Market, and to cause all of the Common Shares to be listed on the Nasdaq Capital Market as soon as practicable following the Closing Date. The
Company further agrees, if the Company applies to have the Common Stock traded on any national securities exchange other than the Nasdaq Capital Market, it will include in such application all of the Common Shares, and will take such other action as
is necessary to cause all of the Common Shares to be listed on such other national securities exchange as promptly as possible. 
 4.10
Section 16. The Company agrees that it will not, prior to the date that is six (6) months from (i) the Closing Date with respect to ALU Part and (ii) the closing of the sale of Common Stock to the TWVC Funds pursuant to the
TWVC Standby Purchase Agreement with respect to the TWVC Funds, consummate a merger or other consolidation that could result in short swing liability under Section 16 of the Exchange Act for ALU Part or the TWVC Funds, respectively; provided,
however, that the foregoing shall not preclude the Company from entering into a definitive agreement with respect to such merger or other business combination. 

4.11 Rights Offering. The Company agrees that promptly following the Closing, it shall file a Form S-1 and promptly following
effectiveness of such Form S-1, commence the Rights Offering for Persons that were Company stockholders of record on the business day immediately prior to the date of this Agreement. 

4.12 Indemnification of Investors. Subject to the provisions of this Section 4.12, the Company will indemnify and hold each
Investor and its directors, officers, stockholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each
Person who controls such Investor (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, stockholders, agents, members, partners or employees (and any other Persons with a
functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, an “Investor Party”) harmless from any and all losses, liabilities,
obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Investor Party may suffer or incur as a
result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against the Investor
Parties in any capacity, or any of them or their respective Affiliates, by any third party who is not an Affiliate of such Investor Party (including for these purposes a derivative action brought on behalf of the Company by any third party who is
not an Affiliate of such Investor Party), arising out of or resulting from the execution, delivery, performance or enforcement of any of the Transaction Documents (unless such action is based upon a breach of such Investor Party’s
representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Investor Party may have with any such third party or any material violations by such Investor Party of state or federal securities laws
or any conduct by such Investor Party which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Investor Party in respect of which indemnity may be sought pursuant to this


  
 26 








 
Agreement, such Investor Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably
acceptable to the Investor Party; provided that the failure to deliver written notice to the Company shall not relieve the Company of any liability to the Investor Party under this Section 4.12, except to the extent that the Company is
materially and adversely prejudiced. Neither the Company nor any Investor Party shall settle any such action without the consent of the applicable Investor Parties or the Company, as the case may be, which consent shall not be unreasonably withheld,
conditioned or delayed. Any Investor Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Investor Party except to
the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action
there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of such Investor Party, in which case the Company shall be responsible for the reasonable fees and
expenses of no more than one such separate counsel for each of the TWVC Funds, collectively, on the one hand, and ALU Part, on the other hand. In the event that the Company does not elect to assume the defense of any action against any Investor
Party in respect of which indemnity may be sought hereunder, then such Investor Party shall have the right to assume the defense of such action with counsel of its own choosing. The indemnification required by this Section 4.12 shall be made by
periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained herein shall be in addition to (x) any cause of action or similar
right of any Investor Party against the Company or others, and (y) any liabilities the Company may be subject to pursuant to law. 

4.13 Board Observer. ALU Part shall be entitled to have one representative attend all meetings of the Company Board and each committee
of the Company Board as an observer, but such observer shall have no voting rights (the “ALU Part Observer”). The Company shall provide the ALU Part Observer with notice of all meetings of the Company Board and each committee of the
Company Board and all written materials distributed to the members of the Company Board and the members of each committee of the Company Board, in each case at the same time and in the same manner as such notices and materials are provided to
members of the Company Board and members of the committees of the Company Board; provided, however, that ALU Part may request that the Company cease providing material non-public information to the ALU Part Observer at any time; and provided
further, that the Company reserves the right to exclude the ALU Part Observer from access to any of such materials or meetings or portions thereof if and to the extent that in the good faith judgment of a majority of the directors of the Company (or
the majority of the subject Board committee) after obtaining the advice of counsel, (i) such exclusion is reasonably necessary to preserve the Company’s attorney-client privilege; (ii) ALU Part has a business or financial interest
(other than by reason of its interest as a stockholder of the Company) that would reasonably be expected to pose a conflict of interest for ALU Part and, if the ALU Part Observer were a member of the Company Board rather than an observer, it would
be advisable under applicable law for the ALU Part Observer to recuse himself or herself due to such conflict of interest; (iii) such access or sharing of information with the ALU Part Observer would reasonably be expected to cause substantial
harm to the Company’s business; or (iv) such access or sharing of information would result in disclosure of confidential information to the ALU Part Observer regarding ALU Part’s competitors, including


  
 27 








 
without limitation, such competitor’s product road maps, terms of sale and contractual or other arrangements. Any ALU Part Observer shall agree to hold in confidence any information provided
to him or her in accordance with the terms of a confidentiality agreement to be entered into that is reasonably satisfactory to the Company and such ALU Part Observer, it being understood that any information provided to the ALU Part Observer may be
provided to directors, officers and employees of ALU Part and its Affiliates who have a business need to know such information and an obligation to hold such information in confidence in accordance with an enforceable non-disclosure agreement
between the Company and ALU Part or one of its Affiliates, currently, the Master Non-Disclosure Agreement No. 7035948 effective as of July 19, 2007 between the Company and Compagnie Financiere Alcatel-Lucent, an Affiliate of ALU Part (the
“MNDA”), and ALU Part further agrees that it, or one of its Affiliates will enter into a subordinate disclosure agreement with the Company covering the subject matter of this Section 4.13. The Company agrees that it will
indemnify the ALU Part Observer for any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of
investigation that the ALU Part Observer may suffer or incur as a result of or relating to, and advance expenses to the ALU Part Observer in connection with, any actions, suits, or proceedings brought against the ALU Part Observer, or to which the
ALU Part Observer is otherwise made a party or witness, by reason of the fact that he or she is the ALU Part Observer; provided, however, that nothing in this Section 4.13 shall obligate the Company to pay any amounts (i) in the
event the ALU Part Observer commits a tortious act; or (ii) in the event of a breach by ALU Part or the ALU Part Observer of the obligations contained in this Section 4.13. The Company shall reimburse the ALU Part Observer for
expenses incurred in connection with attendance at Company Board or committee meetings in accordance with the Company’s travel policy. The rights of ALU Part with respect to this Section 4.13 shall apply until the earlier of
(i) (a) the consolidation or merger of the Company with or into another Person (unless the Company is the surviving corporation and the shareholders of the Company prior to such merger or consolidation continue to hold immediately
thereafter a majority of the Company’s voting stock), (b) the purchase, tender or offer that is accepted by the holders of more than 50% of the outstanding shares of the Company’s voting stock, or (c) the consummation of a stock
purchase agreement or other business combination with another Person whereby the Person acquires more than 50% of the outstanding shares of the Company’s voting stock, or (ii) such time as ALU Part ceases to hold at least 4,878,048 of the
Common Shares purchased from the Company pursuant to this Agreement (subject to stock splits, recapitalization and the like); provided, however, that ALU Part may determine to forego its right to an observer at any time prior thereto, at which time
the Company shall no longer have an obligation to provide notices of meetings or written materials related thereto.

 “Shelf Registration Statement” means the registration statement on Form S-1 (unless the Company is

(b) Suspension of Filing or Registration. If the Company shall furnish to ALU Part a certificate signed by the Chief
Executive Officer or Chief Financial Officer of the Company, stating that the filing, effectiveness or continued use of the Shelf Registration Statement would (i) in the good faith judgment of the Company Board, unreasonably impede, delay or
otherwise interfere with any pending or contemplated material acquisition, corporate reorganization, involving the Company (each, a “Material Transaction”), (ii) based upon advice from the Company’s investment banker or
financial advisor, materially adversely affect any pending or contemplated financing, offering or sale of any class of securities by the Company, or (iii) in the good faith judgment of the Company Board require disclosure of material non-public

provided, however, that in the case of a Suspension (as defined below) pursuant to clause (i) or (ii) above, the Suspension shall earlier terminate upon the completion or abandonment of the relevant securities offering or
sale, financing, or Material Transaction unless the Suspension is also permitted for a different reason under clauses (i) or (ii), and provided, further, that in the case of a Suspension pursuant to clause (ii) above, the
Company shall give written notice of its determination to suspend the Shelf Registration Statement and the Suspension shall earlier terminate upon public disclosure by the Company or public admission by the Company of such material non-public

of a Shelf Registration Statement that has been declared effective, to suspend the use by ALU Part of the Shelf Registration Statement (in each case, a “Suspension”). In the case of a Suspension that occurs after the effectiveness
of the Shelf Registration Statement, ALU Part agrees to suspend use of the applicable Prospectus in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon receipt of the notice referred to above. The
Company shall immediately notify ALU Part upon the termination of any Suspension, and (i) in the case that the Shelf Registration Statement has not been declared effective, shall promptly thereafter file the Shelf Registration Statement and use
its reasonable best efforts to have the Shelf Registration Statement declared effective under the Securities Act and (ii) in the case of an effective Shelf Registration Statement, shall amend or supplement the Prospectus, if necessary, so it
does not contain any untrue statement or omission and furnish to ALU Part such numbers of copies of the Prospectus as so amended or supplemented as ALU Part may reasonably request. The Company may only exercise its right to a Suspension once in any
twelve-month period. 

  
 32 








 (c) The Company shall use its commercially reasonable efforts to take all actions
reasonably necessary to ensure that the transactions contemplated herein are effected as so contemplated in Section 6.2(a) hereof, and to submit to the SEC, within two (2) Business Days after the Company learns that no review of the
Shelf Registration Statement will be made by the staff of the SEC or that the staff has no further comments on the Shelf Registration Statement, as the case may be, a request for acceleration of effectiveness (or post-effective amendment, if
applicable) of the Shelf Registration Statement to a time and date not later than 48 hours after the submission of such request. 

(d) Any reference herein to a Shelf Registration Statement or prospectus as of any time shall be deemed to include any document
incorporated, or deemed to be incorporated, therein by reference as of such time and any reference herein to any post-effective amendment to a Shelf Registration Statement as of any time shall be deemed to include any document incorporated, or
deemed to be incorporated, therein by reference as of such time. Any reference to a prospectus as of any time shall include any supplement thereto, preliminary prospectus, or any free writing prospectus in respect thereof.

by ALU Part and use reasonable efforts to cause the Shelf Registration Statement to become effective as soon as reasonably practicable but in any case within the time periods specified in Section 6.2(a). 

(e) In connection with the registration, the Company may require ALU Part, to furnish to the Company such information regarding
ALU Part, including, without limitation, its intended method of distribution of Registrable Securities as may be required in order to comply with the Securities Act. ALU Part agrees to notify the Company as promptly as practicable of any inaccuracy
or change in information previously furnished by ALU Part to the Company or of the occurrence of any event in either case that could cause the prospectus to contain an untrue statement of a material fact regarding ALU Part or its intended method of
disposition of such Registrable Securities or omits to state any material fact regarding ALU Part or its intended method of disposition of such Registrable Securities required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing, and promptly to furnish to the Company any additional information required to correct and update any previously furnished information or required so that such prospectus shall not contain, with
respect to ALU Part or the disposition of such Registrable Securities, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the
circumstances then existing. If ALU Part fails to provide to the Company any information required to be provided pursuant to this Section 6.2 after ALU Part became aware of the inaccuracy, omission or required change, the Company may
suspend the use of the Shelf Registration Statement and the Prospectus contained therein until such time as ALU Part provides the required information to the Company.

 6.3 Piggyback Registration. 

(a) Company Registration. If at any time or from time to time the Company shall determine to register any of its equity
securities, either for its own account or for the account of security holders (other than (i) in a registration relating solely to employee benefit plans, (ii) a registration on Form S-4 or S-8 (or such other similar successor forms then
in effect under the Securities Act), (iii) a registration pursuant to which the Company is offering to exchange its own securities, (iv) a registration statement relating solely to dividend reinvestment or similar plans, or (v) a
resale shelf registration statement relating solely to debt securities of the Company that are convertible into Common Stock and the underlying shares of Common Stock, the Company will: 

(i) promptly (but in no event less than 20 days before the effective date of the relevant Registration Statement) give to ALU
Part written notice thereof; and 
 (ii) include in such registration (and any related qualification under state securities
laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests, made within 10 days after receipt of such written notice from the Company, by ALU Part, except as set
forth in Section 6.2(b) below. 
 (b) Underwriting. If the registration of which the Company gives notice
is for a registered public offering involving an underwriting, the Company shall so advise ALU Part as a part of the written notice given pursuant to Section 6.3(a)(i). In such event the right of ALU Part to registration pursuant to this
Section 6.3 shall be conditioned upon ALU Part’s participation in such underwriting and the inclusion of ALU Part’s Registrable Securities in the underwriting to the extent provided herein in subject to the limitations
expressed in Section 6.2. ALU Part shall, together with the Company and the other parties distributing their securities through such underwriting, enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Section 6.3, if the underwriter determines that marketing factors require a limitation of the number of shares to be underwritten,
the underwriter may limit the number of Registrable Securities to be included in the registration and underwriting, subject to the terms of this Section 6.3. The Company shall so advise all holders of the Company’s securities that
would otherwise be registered and underwritten pursuant hereto, and the number of shares of such securities, including Registrable Securities, that may be included in the registration and underwriting shall be allocated first to the Company and
second to ALU Part and any other holders with registration rights on a pro rata basis based on the total number of securities subject to registration rights held by such Persons. No such reduction shall (i) reduce the securities being offered
by the Company for its own account to be included in the registration and underwriting, or (ii) subject to the limitations expressed in Section 6.2, reduce the amount of securities of ALU Part and the


  
 34 








 
TWVC Funds included in the registration below thirty percent (30%) of the total amount of securities included in such registration. No securities excluded from the underwriting by reason of
the underwriter’s marketing limitation shall be included in such registration. For the avoidance of doubt, nothing in this Section 6.3(b) is intended to diminish the number of securities to be included by the Company in the
underwriting. 
 (c) Market Stand Off. In the event the Company files a Piggyback Registration Statement pursuant to
this Section 6.3 for an underwritten offering, ALU Part hereby agrees that, upon the request of the underwriters, during the period ending on the date that is ninety (90) days after the date of the final prospectus relating to such
Piggyback Registration Statement or such other period as may be reasonably requested by an underwriter to accommodate regulatory restrictions on (1) the publication or other distribution of research reports and (2) analyst recommendations
and opinions, including, but not limited to, the restrictions contained in FINRA Rule 2711(f)(4) (or any successor provisions or amendments thereto), ALU Part will not, without the prior written consent of the underwriter, directly or indirectly,
(1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of any Registrable Securities,
(2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Registrable Securities or (3) engage in any short selling of the Common Stock or securities
convertible into or exercisable or exchangeable for Common Stock. The foregoing shall not apply to (a) the sale of any Registrable Securities to an underwriter pursuant to an underwriting agreement; (b) any transfers to any stockholder,
partner or member of, or owner of a similar equity interest in ALU Part, as the case may be, if, in any such case, such transfer is not for value; and (c) any transfer made by ALU Part (i) in connection with the sale or other bona fide
transfer in a single transaction of all or substantially all of ALU Part’s or any of ALU Part’s Affiliate’s capital stock, partnership interests, membership interests or other similar equity interests, as the case may be, or all or
substantially all of its assets, in any such case not undertaken for the purpose of avoiding the restrictions hereunder or (ii) to another corporation, partnership, limited liability company or other business entity so long as the transferee is
an affiliate and such transfer is not for value; provided, however, transfers pursuant to clauses (b) and (c)(ii), any such transferees shall agree in writing to be bound by this Section 6.3(c). The underwriters in connection with
such registration are intended third party beneficiaries of this Section 6.3(c) and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto. ALU Part further agrees to execute such
agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Section 6.3(c) or that are necessary to give further effect thereto. The foregoing provisions of this
Section 6.3(c) shall be applicable to ALU Part only if all officers and directors of the Company and all stockholders owning more than 5% of the Company’s outstanding Common Stock, at the time the Company provides written notice of
an underwritten registered public offering pursuant to Section 6.3(a)(i), are subject to the same restrictions. Any discretionary waiver or termination of the restrictions of any similar agreement or restriction pertaining to other
stockholders by the Company or the underwriters shall apply pro rata to ALU Part, based on the number of shares subject to such agreements. 

(d) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration
initiated by it under this Section 6.3 prior to the effectiveness of such registration whether or not ALU Part has elected to include securities in such registration. 

  
 35 








 6.4 Expenses of Registration. All expenses incurred in connection with all registrations
effected pursuant to Section 6.2, including all registration, SEC, stock exchange, filing and qualification fees (including state securities law fees and expenses), printing expenses, messenger and delivery expenses, escrow fees, accounting
fees, fees and disbursements of counsel for and independent public accountants of the Company, fees and expenses of all Persons retained by the Company and fees and disbursements of one special counsel for ALU Part (not to exceed $50,000) shall be

The Company shall furnish to Legal Counsel copies of any correspondence from the SEC or the staff of the SEC to the Company or its representatives relating to the Registration Statements;

requirements of the Securities Act and the rules and regulations of the SEC thereunder or contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing (the Company shall use its commercially reasonable efforts to promptly prepare a supplement or amendment to the Registration Statement to conform to such requirements or to correct such

registration of any of the Company’s securities that are superior to, or more expansive than, those granted to ALU Part hereunder until such time as ALU Part has sold all of its Registrable Securities. 

6.7 Indemnification. For the avoidance of doubt, the indemnification provisions set forth in this Section 6.7 only apply to those
matters set forth in Article 6. All other Articles and Sections of the Agreement shall be governed by Section 4.12, except for indemnification rights related to the ALU Part Observer that are covered by Section 4.13. 

(a) Indemnification by the Company. To the extent permitted by law, the Company shall, and it hereby agrees to,
indemnify and hold harmless ALU Part, each of ALU Part’s officers, directors, employees, partners and agents, each Person controlling ALU Part, and each person who participates as a placement or sales agent or as an underwriter in any offering
or sale of the Registrable Securities, against any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) (collectively, “Claims”) arising out of or are based upon (i) any untrue statement or
alleged untrue 

  
 39 








 
statement of a material fact contained in any registration statement, or any preliminary or final prospectus contained therein, or any amendment or supplement thereto, or any document
incorporated by reference therein, (iii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not
misleading, (iv) any violation or alleged violation by the Company of any federal, state or common law rule or regulation applicable to the Company in connection with any such registration, qualification or compliance or (v) any failure to
register or qualify Registrable Securities in any state where the Company or its agents have affirmatively undertaken or agreed that the Company will undertake such registration or qualification on behalf of ALU Part, and the Company shall, and it
hereby agrees to, promptly reimburse each Investor or any such agent or underwriter for any legal or other out-of-pocket expenses reasonably incurred by them in connection with investigating or defending any such Claims, provided,
however, that the Company shall not be liable to any such person in any such case to the extent that any such Claims arise out of or are based upon an untrue statement or alleged untrue statement or omission made in such registration
statement, or preliminary or final prospectus, or amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by ALU Part or any agent, underwriter or representative of ALU Part expressly for
use in such registration statement, or preliminary or final prospectus, or amendment or supplement thereto, or by ALU Part’s failure to furnish the Company, upon request, with the information with respect to ALU Part, or any agent, underwriter
or representative of ALU Part, or ALU Part’s intended method of distribution, that is the subject of the untrue statement or omission or if the Company shall sustain the burden of proving that ALU Part or such agent or underwriter sold
securities to the person alleging such Claims without sending or giving, at or prior to the written confirmation of such sale, a copy of the applicable prospectus (excluding any documents incorporated by reference therein) or of the applicable
prospectus, as then amended or supplemented (excluding any documents incorporated by reference therein), if the Company had previously furnished copies thereof to ALU Part or such agent or underwriter, and such prospectus corrected such untrue
statement or alleged untrue statement or omission or alleged omission made in such registration statement. 
 (b)
Indemnification by ALU Part. To the extent permitted by law, ALU Part shall, and hereby agrees to (i) indemnify and hold harmless the Company, its directors, officers, employees and each Person controlling the Company and each
underwriter, its partners, officers, directors, employees and each Person controlling such underwriter in any offering or sale of Registrable Securities, against any Claims to which the Company, its directors, officers, employees and each Person
controlling the Company may become subject, insofar as such Claims (including any amounts paid in settlement as provided herein), or actions or proceedings in respect thereof, arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in such registration statement, or any preliminary or final prospectus contained therein, or any amendment or supplement thereto, or arise out of or are based upon any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made


  
 40 








 
in reliance upon and in conformity with written information furnished to the Company by ALU Part or any agent, underwriter, or representative (as the case may be) expressly for use therein, and
(ii) will promptly reimburse the Company for any legal or out of pocket expenses reasonably incurred by the Company in connection with investigating or defending any such Claim; provided that in no event shall any indemnification and
reimbursement obligations under this Section 6.7(b) exceed the gross proceeds from the offering received by ALU Part, net of any underwriter discounts or placement agent fees and it is understood and agreed that the indemnification
obligations of ALU Part pursuant to any underwriting agreement entered into in connection with any registration statement shall be limited to the obligations contained in this Section 6.7(b). 

(c) Each party entitled to indemnification under this Section 6.7 (the “Indemnified Party”) shall
give notice to the party required to provide such indemnification (the “Indemnifying Party”) of any Claim as to which indemnification may be sought promptly after such Indemnified Party has actual knowledge thereof, and shall permit
the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such Claim, shall be subject to approval by the
Indemnified Party (whose approval shall not be unreasonably withheld) and the Indemnified Party may participate in such defense at the Indemnifying Party’s expense if (i) representation of such Indemnified Party would be inappropriate due
to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding or (ii) the Indemnifying Party shall have failed to promptly assume the defense of such proceeding; and
provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Article VI, except to the extent that such failure to give
notice shall materially adversely affect the Indemnifying Party in the defense of any such Claim. No Indemnifying Party, in the defense of any such claim or litigation, may, without the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement unless such settlement includes an unconditional release of such Indemnified Party from all liabilities on claims that are the subject matter of such Claim. 

(d) In order to provide for just and equitable contribution in case indemnification is unavailable to an Indemnified Party (by
reason of legal prohibition or otherwise), the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Claim in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such Claim, as well as any other relevant equitable considerations. The relative fault of such Indemnifying
Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of material fact or omission or alleged omission to state a material fact, has been
made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such actions; provided,
however, that, in any case, (i) ALU Part will not be required to contribute any amount in excess of the public offering price of all securities offered by it pursuant to the Shelf Registration Statement


  
 41 








 
(less all underwriting fees and discounts), and (ii) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to
contribution from any Person who was not guilty of such fraudulent misrepresentation. 
 (e) The indemnity and contribution
agreements contained herein are in addition to any liability that the Indemnifying Party may have to the Indemnified Parties and shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Party or
any officer, director or controlling Person of such Indemnified Party and shall survive the transfer of the Registrable Securities. 
 6.8
Information by ALU Part. ALU Part shall furnish to the Company such information regarding ALU Part and the distribution proposed by ALU Part as the Company may reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Article 6.8. 
 6.9 Transfer of Registration Rights. The rights
contained in Section 6.2 hereof to cause the Company to register the Registrable Securities, and the other rights set forth in this Article VI, may be assigned or otherwise conveyed by ALU Part to any transferee of the Registrable
Securities if the transfer was permitted under Section 4.1. 
 6.10 Rule 144 Reporting. With a view to making available
to ALU Part the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to: 

(a) make and keep current public information available, within the meaning of Rule 144 or any similar or analogous rule
promulgated under the Securities Act; and 
 (b) file with the SEC, in a timely manner, all reports and other documents
required of the Company under the Securities Act and Exchange Act; 
 (c) as long as ALU Part owns any Registrable
Securities, furnish in writing upon such Investor’s written request a written statement by the Company that it has complied with the reporting requirements of Rule 144 and of the Securities Act and Exchange Act; and 

(d) undertake any additional actions reasonably necessary to maintain the availability of the use of Rule 144. 

6.11 Termination of Registration Rights. The rights of ALU Part under Article VI hereof shall terminate on the date when there
no longer remaining any Registrable Securities; provided that Section 6.4 and Section 6.8 shall survive such termination. 

ARTICLE VII

AND HEREBY IRREVOCABLY WAIVE, AND AGREE NOT TO ASSERT IN ANY SUIT, ACTION OR PROCEEDING BROUGHT BY THE 

  
 44 








 
COMPANY OR THE INVESTORS, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF ANY SUCH COURT, OR THAT SUCH SUIT, ACTION OR PROCEEDING IS IMPROPER. EACH PARTY, AFTER CONSULTING OR
HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, EACH KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE IRREVOCABLY, ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS ARISING OUT OF OR RELATING TO THIS
AGREEMENT (INCLUDING WITH RESPECT TO THE ENFORCEMENT OF ANY OF THE TRANSACTION DOCUMENTS) AND SUCH PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. 

7.10 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission or email attachment, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or
email-attached signature page were an original thereof. 
 7.11 Survival. The representations and warranties of the Company contained
herein shall survive the Closing. The covenants of the Company and the Investors contained in this Agreement shall terminate on the Closing Date; provided, that the covenants that by their terms are required to be performed in whole or in part
following the Closing Date shall survive the Closing Date. 
 7.12 Severability. If any provision of this Agreement is prohibited by
law or otherwise held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree
upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement. 

7.13 Replacement of Certificate. If any certificate or instrument evidencing any Company Shares is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company for any losses in connection
therewith. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Company Shares. 

7.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages,
each of the Investors and the Company will be entitled to seek specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any


  
 45 








 
breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation (other than in connection with any action for
temporary restraining order) the defense that a remedy at law would be adequate. 
 7.15 Adjustments in Share Numbers and Prices. In
the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock),
combination or other similar recapitalization or event occurring after the date hereof and prior to the Closing, each reference in any Transaction Document to a number of shares or a price per share shall be amended to appropriately account for such
event. 
 7.16 Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under any Transaction
Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any Transaction Document. The decision of each Investor
to purchase Common Shares pursuant to this Agreement has been made by such Investor independently of any other Investor and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets,
properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company which may have been made or given by any other Investor or by any agent or employee of any other Investor, and no Investor or any of its
agents or employees shall have any liability to any other Investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Transaction Document, and no action
taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a
group with respect to such obligations or the transactions contemplated by the Transaction Document. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that
no other Investor will be acting as agent of such Investor in connection with monitoring its investment hereunder. Each Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out
of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose.
