organization (as applicable), with the requisite corporate power and authority to own and use its properties and assets and to carry on its business as currently conducted. Neither the Company nor the Subsidiary is in violation of any of the
provisions of its respective certificate or articles of incorporation, bylaws or other organizational or charter documents. Each of the Company and the Subsidiary is duly qualified to conduct business and is in good standing 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 (i) a material adverse effect on the legality, validity or enforceability of any Transaction Document, (ii) a material adverse effect on the results of operations, assets, business or financial condition of the
Company and the Subsidiary, taken as a whole, or (iii) a material adverse effect on the Company’s ability to perform in any material respect on a timely basis its obligations under any Transaction Document (any of (i), (ii) or (iii), a

 (c) Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents and otherwise to carry out its obligations
thereunder. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been duly authorized by all necessary action on the part of the Company and no
further action is required by the Company in connection therewith. Each Transaction Document has been (or upon delivery will have been) duly executed by the Company and, 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 (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of
creditors’ rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies, and (iii) as limited by public policy. 
  
 (d) No Conflicts. The execution, delivery and
performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated thereby do not and will not (i) conflict with or violate any provision of the Company’s or the Subsidiary’s
certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that 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 (with or 







 without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument

which any property or asset of the Company or the Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as would not have or reasonably be expected to result in a Material Adverse Effect. 
  
 (e) Filings, Consents and Approvals. Other than as
set forth in Section 2.2(f) hereof, the Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental
authority or other Person in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than (a) the filing with the Commission of the Registration Statement, the application(s) to each Trading Market
for the listing of the Shares, Warrant Shares and Option Shares for trading thereon in the time and manner required thereby, and applicable Blue Sky filings, (b) such as have already been obtained or such exemptive filings as are required to be made
under applicable securities laws, and (c) such other filings as may be required following the Closing Date under the Securities Act, the Exchange Act and corporate law. 
  
 (f) Issuance of the Securities. The Securities are duly authorized and, when issued and paid for in
accordance with the Transaction Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens. The Company has reserved from its duly authorized capital stock the maximum number of shares of Common Stock
issuable pursuant to this Agreement and the Warrants.

exchangeable into shares of Common Stock. The issue and sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than the Purchasers) and will not result in a right of any holder
of Company securities to adjust the exercise, conversion, exchange or reset price under such securities.

the Exchange Act, including pursuant to Section 13(a) or 15(d) of the Exchange Act, for the two years preceding the date hereof (or such shorter period as the Company was required by law to file such material) (the foregoing materials, including the

 (k) Compliance. Except as disclosed in the SEC

property owned by them that is material to the business of the Company and the Subsidiary, taken as a whole, in each case free and clear of all Liens, except for Liens as do not materially affect the value of such property and do not materially
interfere with the use made and proposed to be made of such property by the Company and the Subsidiary and Liens for the payment of federal, state or other taxes, the payment of which is neither delinquent nor subject to penalties. Any real property

 (0) Transactions With Affiliates and
Employees. Except as set forth in the SEC Reports, none of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or the

otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or

established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company, including the
Subsidiary, is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s Form 10-K or 10-Q, as the case may be, is being prepared. The Company’s certifying officers have
evaluated the effectiveness of the Company’s controls and procedures as of the end of the quarter ended September 27, 2003 (such date, the “Evaluation Date”). The Company presented in its Form 10-Q for the quarter ended
September 27, 2003 the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes
in the Company’s internal control over financial reporting (as such term is defined in Exchange Act Rules 13a-15 and 15d-15) or, to the Company’s knowledge, in other factors that could significantly affect the Company’s internal
control over financial reporting.

necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s
Certificate of Incorporation (or similar charter documents) or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result of the Purchasers and the Company fulfilling their obligations or exercising their
rights under the Transaction Documents, including without limitation the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.

risks of such investment. Such Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment. 
  
 (e) General Solicitation. Such Purchaser is not
purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or
any other general solicitation or general advertisement. 
  
 (f) Registration Required. Such Purchaser hereby covenants with the Company not to make any sale of the Shares, Warrant Shares or Option Shares without complying with the provisions hereof and of the
Registration Rights Agreement, and without effectively causing the prospectus delivery requirement under the Securities Act to be satisfied (unless such Purchaser is selling such Shares, Warrant Shares or Option Shares in a transaction not subject
to the prospectus delivery requirement), and such Purchaser acknowledges that the certificates evidencing the Shares, Warrant Shares or Option Shares will be imprinted with a legend that prohibits their transfer except in accordance therewith.

  
 (g) No Tax or Legal Advice. Such
Purchaser understands that nothing in this Agreement, any other Transaction Document or any other materials presented to such Purchaser in connection with the purchase and sale of the Securities constitutes legal, tax or investment advice. Such
Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of Securities. 
  
 ARTICLE IV 
 OTHER
AGREEMENTS OF THE PARTIES 
  
 4.1 Transfer Restrictions.
 
  
 (a) The Securities may only be
disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement, to the Company, to an Affiliate of a Purchaser or in connection with a pledge
as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such
transfer does not require registration of such transferred Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights of a
Purchaser under this Agreement and the Registration Rights Agreement. 







 (b) The Purchasers agree to the imprinting, so long as is required by this Section
4.1(b), of a legend on any of the Securities in the following form: 
  
 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”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN 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 ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THESE SECURITIES
MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT. 
  
 The Company acknowledges and agrees that a Purchaser may
from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Securities to a financial institution that is an “accredited investor” as defined in Rule
501(a) under the Securities Act and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the
Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the Company will
execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including the preparation and filing of any required prospectus
supplement under Rule 424(b)(3) under the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder. 
  
 (c) Certificates evidencing the Shares, Warrant Shares and Option Shares shall not contain any legend
(including the legend set forth in Section 4.1(b)), (i) while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Shares,
Warrant Shares or Option Shares pursuant to Rule 144, or (iii) if such Shares, Warrant Shares or Option Shares are eligible for sale under Rule 144(k), or (iv) if such legend is not required under applicable requirements of the Securities Act
(including judicial interpretations and pronouncements issued by the Staff of the Commission). The Company shall cause its counsel to issue a legal opinion to the Company’s transfer agent promptly after the Effective Date if required by the
Company’s transfer agent to effect the removal of the legend hereunder. If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant 







 Shares, such Warrant Shares shall be issued free of all legends. The Company agrees that following the
Effective Date or at such time as such legend is no longer required under this Section 4.1(c), it will, no later than five (5) Trading Days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate
representing Shares, Warrant Shares or Option Shares, as the case may be, issued with a restrictive legend, deliver or cause to be delivered to such Purchaser a certificate representing such Securities that is free from all restrictive and other
legends. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section. 
  
 (d) In addition to such Purchaser’s other available
remedies, the Company shall pay to a Purchaser, in cash, as liquidated damages and not as a penalty, for each $1,000 of Shares or Warrant Shares (based on the Closing Price of the Common Stock on the date such Securities are submitted to the
Company’s transfer agent) subject to Section 4.1(c), $10 per Trading Day (increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue) for each Trading Day after such fifth (5th) Trading Day until such certificate is delivered. Nothing herein shall limit such Purchaser’s right to pursue actual
damages for the Company’s failure to deliver certificates representing any Securities as required by the Transaction Documents, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity including,
without limitation, a decree of specific performance and/or injunctive relief. 
  
 (e) Each Purchaser severally and not jointly agrees that the removal of the restrictive legend from certificates representing Securities
as set forth in this Section 4.1 is predicated upon the Company’s reliance that the Purchaser will sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery
requirements, or an exemption therefrom. 
  
 4.2 Furnishing of Information.
As long as any Purchaser owns Securities, the Company covenants 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. Upon the request of any such holder of Securities, the Company shall deliver to such holder a written certification of a duly authorized officer as to whether it has complied with the preceding sentence. As long as any Purchaser
owns Securities, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers
to sell the Securities under Rule 144. 
  
 4.3 Integration. The Company
shall not 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 Securities in a manner that would
require the registration under the Securities Act of the sale of the Securities to the Purchasers or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market. The Company
covenants to obtain shareholder approval prior to closing any subsequent transaction that may be deemed to be integrated with this offering for the purposes of the rules of the Nasdaq Stock Market. 







 4.4 Securities Laws Disclosure; Publicity. The Company shall, by 8:30 a.m. Eastern time on the Business Day
following the date of this Agreement, issue a press release or file a Current Report on Form 8-K, in each case reasonably acceptable to each Purchaser disclosing the transactions contemplated hereby. The Company and each Purchaser shall consult with
each other in issuing any press releases with respect to the transactions contemplated hereby, and neither the Company nor any Purchaser shall issue any such press release or otherwise make any such public statement without the prior consent of the
Company, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any press release of the Company, which consent shall not unreasonably be withheld, except if such disclosure is required by
law, in which case the disclosing party shall promptly provide the other party with notice of such public statement or communication. Notwithstanding the foregoing, other than as set forth above, the Company shall not publicly disclose the name of
any Purchaser, or include the name of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (i) as required by federal securities law in connection
with the registration statement contemplated by the Registration Rights Agreement and (ii) to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of
such disclosure permitted under subclause (i) or (ii). 
  
 4.5 Shareholders
Rights Plan. No claim will be made or enforced by the Company or any other Person that any Purchaser is an “Acquiring Person” under any shareholders rights plan or similar plan or arrangement in effect or hereafter adopted by the
Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers.

  
 4.6 Non-Public Information. The Company covenants and agrees that
neither it nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto such Purchaser shall have
executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Purchaser shall be relying on the foregoing representations in effecting transactions in securities of the
Company. 
  
 4.7 Use of Proceeds. The Company shall use the net proceeds
from the sale of the Securities hereunder for working capital and other general purposes. 
  
 4.8 Indemnification of Purchasers. The Company will indemnify and hold the Purchasers and their directors, officers, shareholders, partners, employees and agents (each, a “Purchaser 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 Purchaser Party may suffer or incur as a result of or relating to: (a) any misrepresentation, breach or inaccuracy, or any allegation by a third party that, if true, would constitute a breach or inaccuracy, 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 cause of action, suit or claim brought or made against such Purchaser Party and arising solely out of or solely resulting
from the execution, delivery, performance or enforcement of this Agreement or any of the other Transaction Documents and without causation by any other activity, obligation, 







 condition or liability pertaining to such Purchaser. The Company will reimburse such Purchaser for its reasonable legal
and other expenses (including the cost of any investigation, preparation and travel in connection therewith) incurred in connection therewith, as such expenses are incurred. 
  
 4.9 Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep
available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares and Option Shares pursuant to this Agreement and Warrant Shares pursuant to the Warrants.

  
 4.10 Listing of Common Stock. The Company hereby agrees to use
commercially reasonably efforts to maintain the listing of the Common Stock on the Trading Market, and as soon as reasonably practicable following the Closing (but not later than the earlier of the Effective Date and the first anniversary of the
Closing Date) to list the applicable Shares, Warrant Shares and Option Shares on the Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other Trading Market, it will include in such application
the Shares, Warrant Shares and Option Shares, and will take such other action as is necessary or desirable in the opinion of the Purchasers to cause the Shares, Warrant Shares and Option Shares to be listed on such other Trading Market as promptly
as possible. 
  
 4.11 Subsequent Equity Sales. From the date hereof until
30 days after the Effective Date, neither the Company nor the Subsidiary shall issue additional shares of Common Stock or Common Stock Equivalents. Notwithstanding anything to the contrary herein, this Section 4.11 shall not apply to the following:
(a) the granting of options to employees, officers and directors of the Company pursuant to any stock option plan duly adopted by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a
committee of non-employee directors established for such purpose, or (b) the exercise of any security issued by the Company in connection with the offer and sale of the Company’s securities pursuant to this Agreement, or (c) the exercise of or
conversion of any convertible securities, options or warrants issued and outstanding on the date hereof, provided such securities have not been amended since the date hereof, (d) acquisitions or strategic investments, the primary purpose of which is
not to raise capital, (e) issuances of equity shares of Common Stock or Common Stock Equivalents in connection with or in contemplation of strategic alliances or corporate collaborations with non-financial purchasers, or (f) up to $6,600,000 worth
of Common Stock or Common Stock Equivalents. 
  
 ARTICLE V

 MISCELLANEOUS 
  
 5.1 Fees and Expenses. Except as otherwise set forth in this Agreement, each party shall pay the fees and expenses of its advisers, counsel, accountants and other
experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement, except that the Company shall reimburse the Purchasers for the fees and expenses of legal
counsel to the Purchasers, up to an aggregate maximum of $25,000. The Company shall pay all stamp and other taxes and duties levied in connection with the sale of the Securities. 







 5.2 Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the
entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents,
exhibits and schedules. 
  
 5.3 Notices. Any and all notices or other
communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered via facsimile at
the facsimile number specified on the signature pages attached hereto prior to 6:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at
the facsimile number on the signature pages attached hereto on a day that is not a Trading Day or later than 6:30 p.m. (New York City time) on any Trading Day, (c) the Trading Day following the date of mailing, if sent by U.S. nationally recognized
overnight courier service, or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature pages attached hereto. 
  
 5.4 Amendments; Waivers. No provision of this Agreement may be waived or amended
except in a written instrument signed, in the case of an amendment, by the Company and each Purchaser or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any default with respect to any
provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission
of either party to exercise any right hereunder in any manner impair the exercise of any such right. 
  
 5.5 Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this
Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. 
  
 5.6 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their
successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of each Purchaser. Any Purchaser may assign any or all of its rights under this Agreement to any
Person to whom such Purchaser assigns or transfers at least 50% of the amount of Securities originally purchased by such Purchaser hereunder, provided such transferee agrees in writing to be bound, with respect to the transferred Securities, by the
provisions hereof that apply to the “Purchasers.” 
  
 5.7 No
Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

  
 5.8 Governing Law. All questions concerning the construction, validity,
enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the Commonwealth of Massachusetts, without regard to the principles of conflicts of law thereof. Each
party agrees that all legal proceedings concerning the 







 interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction
Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in Delaware. Each party hereto hereby
irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in Delaware for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including
with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is improper. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by delivering a copy thereof via overnight delivery
(with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be
deemed to limit in any way any right to serve process in any manner permitted by law. Each party hereto (including its affiliates, agents, officers, directors and employees) hereby irrevocably waives, to the fullest extent permitted by applicable
law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. If either party shall commence an action or proceeding to enforce any provisions of a Transaction
Document, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its attorneys fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

  
 5.9 Survival. The representations and warranties contained herein shall
terminate upon the Closing and delivery of the Shares. 
  
 5.10 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, 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 signature page were an original thereof. 
  
 5.11 Severability. If any provision of this Agreement is 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. 
  
 5.12 Replacement of Securities.
If any certificate or instrument evidencing any Securities 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 customary and reasonable indemnity, if requested. 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 Securities. 







 5.13 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including
recovery of damages, each of the Purchasers and the Company will be entitled to 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
breach of obligations described in the foregoing sentence and hereby agree to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. 
  
 5.14 Independent Nature of Purchasers’ Obligations and Rights. The obligations of
each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction
Document. Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers 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 Purchaser 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 Purchaser to be joined as an additional party in any proceeding for
such purpose. Each Purchaser has been represented by its own separate legal counsel in their review and negotiation of the Transaction Documents. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the
convenience of the Company and not because it was required or requested to do so by the Purchasers.
