“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SECTION 1145 OF THE
BANKRUPTCY REFORM ACT OF 1978, AS AMENDED (THE “BANKRUPTCY CODE”), AND MAY BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED WITHOUT REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES


  
 5 








 
ACT”), PROVIDED THAT THE HOLDER IS NOT DEEMED TO BE AN UNDERWRITER AS SUCH TERM IS DEFINED IN SECTION 1145(B) OF THE BANKRUPTCY CODE. IF THE HOLDER IS DEEMED TO BE AN UNDERWRITER AS SUCH
TERM IS DEFINED IN SECTION 1145(B) OF THE BANKRUPTCY CODE, THEN THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED (1) PURSUANT TO (A) A REGISTRATION STATEMENT WITH RESPECT TO SUCH
SECURITIES THAT IS EFFECTIVE UNDER THE SECURITIES ACT OR (B) AN AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT RELATING TO THE DISPOSITION OF SECURITIES AND (2) IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS
CERTIFICATE MUST BE SURRENDERED TO BROADVIEW NETWORKS HOLDINGS, INC. (THE “COMPANY”) OR ITS TRANSFER AGENT AS A CONDITION PRECEDENT TO THE SALE, PLEDGE OR OTHER TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE. 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO A STOCKHOLDERS’ AGREEMENT DATED AS OF NOVEMBER 13, 2012 AMONG THE
COMPANY AND CERTAIN OF ITS STOCKHOLDERS (AS AMENDED FROM TIME TO TIME). A COPY OF SUCH AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.” 

(2) In the event that the Company determines that shares of Common Stock shall not be represented by a certificate, within a reasonable
amount of time after the issuance of any shares of Common Stock or any Transfer of shares of Common Stock, the Company shall send the registered owner of such shares a notice containing the information contained in Section 3(a)(i)(1) and
any additional information required to be provided under the General Corporation Law of the State of Delaware. 
 (3) Each 4%
Holder agrees, prior to any Transfer of any such shares, to give written notice to the Company of such 4% Holder’s intention to effect such Transfer and to comply in all other respects with the provisions of Section 3(a). Each such
notice shall describe the manner and circumstances of the proposed Transfer. Upon request by the Company, the 4% Holder delivering such notice shall deliver a written opinion, addressed to the Company, of counsel for the 4% Holder of such shares,
stating that in the opinion of such counsel (which opinion and counsel shall be reasonably satisfactory to the Company) such proposed Transfer does not involve a transaction requiring registration or qualification of such shares under the Securities
Act. Such 4% Holder of such shares shall be entitled to effect a Transfer of such shares in accordance with the terms of the notice delivered to the Company, if the Company does not reasonably object to such Transfer and request such opinion within
five (5) Business Days after delivery of such notice, or, if it requests such opinion, does not reasonably object to such Transfer within five (5) Business Days after delivery of such opinion. The Company may only object to such Transfer
if in its reasonable opinion the proposed Transfer involves a transaction requiring registration or qualification of such shares under the Securities Act. Each certificate or other instrument evidencing any such transferred Common Stock shall bear
the legend set forth in Section 3(a)(i)(1) above. Notwithstanding the foregoing, a 4% Holder of Common Stock may Transfer all or a portion of its shares of Common Stock pursuant to a Permitted Transfer without complying with the terms


  
 6 








 
of this Section 3(a)(i)(3) so long as such 4% Holder provides written notice of such Transfer to the Company within three (3) Business Days after the effective date of the
Transfer and the other terms of this Agreement have been satisfied. 
 (ii) Unless otherwise expressly approved by the Board,
prior to the date on which the Company has a class of equity securities registered under Section 12(b) or Section 12(g) of the Exchange Act, no Common Stock shall be Transferred, if such Transfer would (i) constitute a violation of
applicable laws, (ii) result in there being more than 2,000 Holders, or 500 Holders who are not accredited investors (as such term is defined by the Commission), of record of Common Stock as determined pursuant to Section 12(g) of the
Exchange Act or (iii) otherwise require the Company to register the Company’s Common Stock under the Exchange Act or any other applicable federal or state securities laws. 

(b) Right of First Refusal. Each 4% Holder (a “Selling Holder”) hereby unconditionally and irrevocably
grants to the other 4% Holders (other than such 4% Holder) (the “Non-Selling Holders”) a right of first refusal to purchase all or any portion of the Common Stock held by the Selling Holder that the Selling Holder may propose
to Transfer (other than in connection with a Permitted Transfer or an Exit Transfer) at the same price and on the same terms and conditions as those offered to the prospective transferees upon the following terms: 

(i) The Selling Holder shall give the Company prompt written notice (the “Notice of Intent”) of its intention to
Transfer such Common Stock, which Notice of Intent shall include the number of shares of Common Stock to be offered (the “Offered Securities”), and the price, terms and conditions upon which the Selling Holder proposes to
offer such Common Stock (which terms shall not be inconsistent with the terms of this Agreement). The consideration payable pursuant to any Transfer may consist solely of cash. The Company shall provide each Non-Selling Holder with a copy of the
Notice of Intent within three (3) Business Days of receipt from the Selling Holder. 
 (ii) The Non-Selling Holders shall
have the right for a period of ten (10) Business Days from the date on which the Notice of Intent was given by the Company to the Non-Selling Holders (the “Acceptance Period”) to accept all or any portion of the Offered
Securities (including Offered Securities in excess of any such Non-Selling Holder’s ROFR Pro Rata Share) at the purchase price and on the terms stated in the Notice of Intent. Such acceptance shall be made by delivering a written notice to the
Selling Holder and the Company within the Acceptance Period, which notice shall state whether such 4% Holder desires to purchase more than its ROFR Pro Rata Share. If, upon the expiration of the Acceptance Period, the aggregate amount of the Offered
Securities accepted by the Non-Selling Holders exceeds the amount of Offered Securities, the Offered Securities shall be allocated to each accepting Non-Selling Holder based on such Non-Selling Holder’s pro rata share, which shall be the ratio
(the “ROFR Pro Rata Share”) of (A) the number of shares of such Non-Selling Holder’s Common Stock to (B) the total number of shares of all of the Non-Selling Holders’ Common Stock. 

(iii) If effective acceptance shall not have been received pursuant to Sections 3(b)(i)-(ii) above with respect to all of
the Offered Securities, the Company shall have the option for a period of two (2) Business Days to purchase all or any portion of any remaining Offered Securities not subscribed for by Non-Selling Holders at the purchase price and on the terms
stated in the Notice of Intent. Following expiration of this two (2) Business Day period, the Selling Holder shall be free to sell any remaining Offered Securities to a third party in a Transfer that otherwise meets the requirements of this
Section 3 on terms and conditions that it deems acceptable (but at a price not less than the price and on terms not more favorable to the purchaser thereof than the price and terms stated in the Notice of Intent); provided that such sale
takes place within sixty (60) days after the expiration of the Acceptance Period (the “Sale Period”). To the extent the Selling Holder Transfers all or any portion of the Offered 

  
 7 








 
Securities during the Sale Period, the Selling Holder shall promptly notify the Company, and the Company shall promptly notify the Non-Selling Holders, as to (i) the number of shares of
Common Stock, if any, that the Selling Holder then owns, (ii) the number of shares of Common Stock that the Selling Holder has Transferred, (iii) the terms of such Transfer and (iv) the name of the owner(s) to whom Common Stock was
Transferred. If no such sale occurs during the Sale Period, any attempted Transfer of such Common Stock shall be subject to the right of first refusal set forth in this Section 3(b). 

(iv) All Transfers of Offered Securities to the Non-Selling Holders subject to this Section 3(b) shall be consummated
contemporaneously with the Transfer of Securities, if any, to the Company or any third party at the principal offices of the Company on the later of (i) a mutually satisfactory Business Day within fifteen (15) days after the expiration of the
Acceptance Period or (ii) the fifth Business Day following the expiration or termination of all waiting periods under the HSR. The certificates or other instruments evidencing such Offered Securities shall be duly endorsed for transfer and
delivered on such closing date against payment of the purchase price for such Offered Securities, together with all other documents which are necessary to effect such Transfer. 

(c) Tag-Along Rights. Except for a Permitted Transfer and following compliance with Section 3(b) hereof, if one or more
Selling Holders propose a Transfer, in one transaction or in a series of related transactions (a “Tag-Along Sale”), of any Common Stock beneficially owned by such 4% Holders to any third party (other than the Company) in an
amount greater than 2.0% of the outstanding shares of Common Stock, the Non-Selling Holders shall have the right to participate in such Tag-Along Sale on the following terms: 
 (i) The Selling Holder shall give the Company a Notice of Intent. 
 (ii) The
Company shall deliver the Notice of Intent to each Non-Selling Holder within three (3) Business Days of receipt from the Selling Holder. 
 (iii) In connection with any Tag-Along Sale, each Non-Selling Holder shall have the right, in its sole discretion, to sell, for the same price per share being paid to, and otherwise on the same terms and
conditions as, the Selling Holder, its Proportionate Percentage of the aggregate number of shares of Common Stock being sold in the Tag-Along Sale. 
 (iv) The Non-Selling Holders must exercise their “tag-along” rights by giving written notice to the Selling Holder within ten (10) Business Days of the delivery of a Notice of Intent by the
Company to the Non-Selling Holders (the “Tag-Along Acceptance Period”), specifying the number of shares of Common Stock that such Non-Selling Holder desires to include in the Tag-Along Sale. Each 4% Holder exercising these
“tag-along rights” is referred to as a “Tag-Along Holder.” The Selling Holder shall attempt to obtain inclusion in the Tag-Along Sale of the entire number of shares of Common Stock which the Tag-Along Holders desire
to have included in the Tag-Along Sale. In the event the Selling Holder shall be unable to obtain the inclusion of such entire number of shares of Common Stock in such Tag-Along Sale, the number of shares of Common Stock to be sold in the Tag-Along
Sale by the Selling Holder and each Tag-Along Holder shall be reduced on a pro rata basis according to the proportion which the number of shares of Common Stock which each such party desires to have included in the sale bears to the total number of
shares of Common Stock desired by all such parties to have included in the sale. 
 (v) All Transfers of Common Stock pursuant
to this Section 3(c) shall be consummated contemporaneously with the Transfer of Securities, if any, to any third party at the principal offices of the Company on the later of (i) a mutually satisfactory Business Day within fifteen
(15) days after the expiration of the Tag-Along Acceptance Period or (ii) the fifth Business Day following the 

  
 8 








 
expiration or termination of all waiting periods under the HSR, to the extent applicable to such Transfer. The certificates or other instruments evidencing such Common Stock shall be duly
endorsed for transfer and delivered on such closing date against payment of the purchase price for the number of Common Stock to be sold by each Non-Selling Holder, together with all other documents which are necessary in order to effect such
Tag-Along Sale. No party to this Agreement shall Transfer any of its Common Stock to any prospective Transferee if such prospective Transferee declines to allow a Non-Selling Holder to participate in a Tag-Along Sale. 

(vi) All Tag-Along Holders shall execute and deliver any documents reasonably requested by the Selling Holder, including any agreement
containing indemnification obligations (which shall be several and not joint obligations) on the part of the Selling Holder and each Tag-Along Holder, provided that the indemnification obligation of each Tag-Along Holder (i) shall be limited to
the consideration payable to such Tag-Along Holder, in the case of representations and warranties made by such Tag-Along Holder, and (ii) shall be computed pro rata based on the aggregate consideration payable to the Selling Holder and all
Tag-Along Holders, in the case of representations and warranties made by the Company. All Tag-Along Holders shall be liable for their pro rata share of the reasonable costs and expenses incurred in connection with the Tag-Along Sale. No Tag-Along
Holder shall be required to agree to any restrictive covenant in connection with any Tag-Along Sale.

all of the Common Stock beneficially owned by such Drag-Along Holder, on the same terms and conditions as those applicable to the Exiting Holders (in the case of clause (A) and/or that each Drag-Along Holder vote (or consent in writing, as the
case may be) in favor of the merger or consolidation or sale of assets (in the case of clause (B) or clause (C)), and that such Drag-Along Holder shall in all other respects support the transactions contemplated by the Exit Transfer.
Notwithstanding any other provision of this Agreement, the provisions of this Section 3(d) shall not apply to any Transfer of Common Stock in a public offering. 
 (ii) The Exiting Holders shall exercise the rights in Section 3(d)(i) by providing to the Company written notice of any Exit Transfer (the “Drag-Along Notice”), setting

all Holders, in the case of representations and warranties made by the Company. All Drag-Along Holders shall be liable for their pro rata share of the reasonable costs and expenses incurred in connection with the Exit Transfer by the Exiting
Holders. No Drag-Along Holder shall be required to agree to any restrictive covenant in connection with any Exit Transfer. In addition, the Drag-Along Holders shall not exercise any rights of appraisal or dissenters rights that such Holder may have
(whether under applicable law or otherwise) or could potentially have or acquire in connection with any Exit Transfer or any other proposal that is necessary or desirable to consummate the Exit Transfer.

for the price and upon the general terms and conditions specified in the New Securities Notice. If any 4% Holder fails to notify the Company in

writing within such 10-Business Day period of its election to purchase any or all of such 4% Holder’s full Pro Rata Share of an offering of New Securities (a
“NonpurchasingHolder”), then such Nonpurchasing Holder will forfeit the right hereunder to purchase that part of such 4% Holder’s Pro Rata Share of such New Securities that such 4% Holder did not agree to purchase. If a
New Issuance Shortfall occurs, the Unpurchased New Securities shall be allocated to each 4% Holder that has elected to purchase its Pro Rata Share of New Securities and that has elected to purchase Unpurchased New Securities in the event of a New
Issuance Shortfall (each, a “Fully Exercising Rights Holder”) in the amount of their Unpurchased New Securities Share. In the event that the Company is unable to allocate to each Fully Exercising Right Holder its respective
Unpurchased New Securities Share due to the aggregate amount of the Unpurchased New Securities Shares equaling more than the amount of the Unpurchased New Securities, then the Unpurchased New Securities shall be allocated to each Fully Exercising
Rights Holder based on its Oversubscription Pro Rata Share. A Fully Exercising Rights Holder’s “Oversubscription Pro Rata Share” is the ratio of (A) the number of shares of such Fully Exercising Rights Holder’s
Common Stock to (B) the total number of shares of all of the Fully Exercising Rights Holders’ Common Stock. 
 (c)
Failure To Exercise. In the event that the 4% Holders fail to exercise in full the purchase right within the 15-day period following delivery of the New Securities Notice, then the Company will have sixty (60) days thereafter to sell the
New Securities with respect to which the 4% Holders’ rights hereunder were not exercised or to enter into an agreement for the sale of the New Securities (in which event the Company shall have 45 days from the date of the execution of such
agreement to sell the New Securities). Any sale of the New Securities shall be at a price and upon terms and conditions not more favorable to the purchasers thereof than specified in the New Securities Notice to the Rights Holders. In the event that
the Company has not issued and sold the New Securities within the deadlines set forth in this Section 4(c), then the Company shall not thereafter issue or sell any New Securities without again first offering such New Securities to the
Rights Holders pursuant to this Section 4. 
 Section 5. Notices. Any notice provided for in this
Agreement shall be in writing and shall be either personally delivered, or mailed first class mail (postage prepaid, return receipt requested) or sent by reputable overnight courier service (charges prepaid), to the party entitled to receive such
notice or other document at the address set forth on the signature page or the applicable agreement in the form of Exhibit A, Exhibit B or Exhibit C hereto. Any such notice shall be effective and deemed received three days after proper deposit in
the mails. The Company, any 4% Holder or any spouse or legal representative of a 4% Holder may effect a change of address for purposes of this Agreement by giving notice of such change to the Company, and the Company shall, upon the request of any
party hereto, notify such party of such change in the manner provided herein. Until such notice of change of address is properly given, the addresses set forth on the signature page or the applicable agreement in the form of Exhibit A, Exhibit B or
Exhibit C hereto shall be effective for all purposes. 
 Section 6. Financial Statements and Other Information.

 (a) Whether or not required by the rules and regulations of the Commission, the Company shall furnish to the 4% Holders:
(i) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and
Analysis of Financial Condition and Results of Operations” that describes the financial condition and results of operations of the Company and its consolidated subsidiaries (showing in reasonable detail, either on the face of the financial
statements or in the footnotes thereto and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, the financial condition and results of operations of the Company and its Restricted Subsidiaries (as defined in
the Indenture) separate from the financial condition and results of operations 

  
 11 









 
of the Unrestricted Subsidiaries (as defined in the Indenture) of the Company, if any) and, with respect to the annual information only, a report thereon by the Company’s certified
independent accountants; and (ii) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports, in each case within the time periods specified in the Commission’s
rules and regulations. Notwithstanding the foregoing, the Company may satisfy such requirements prior to the effectiveness of the registration statement contemplated by the Registration Rights Agreement, dated as of November 13, 2012 (the
“Registration Rights Agreement”), among the Company, the guarantors named therein and the holders of the 10.5% Senior Secured Notes due 2017, by filing with the Commission such registration statement within the time period
required for such filing as specified in the Registration Rights Agreement, to the extent that any such registration statement contains substantially the same information as would be required to be filed by the Company if it were subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act. 
 (b) In addition, whether or not required by
the rules and regulations of the Commission, the Company shall file a copy of all such information and reports with the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the
Commission will not accept such a filing). The Company shall also furnish to the 4% Holders and prospective purchasers of Common Stock upon their request, the information required to be delivered pursuant to Rule 144(A)(d)(4) under the Securities
Act. 
 (c) Notwithstanding the foregoing, the Company shall be deemed to have furnished such reports to the 4% Holders if it
has filed such reports with the Commission via the EDGAR filing system, and such reports are publicly available. 
 (d) The
Company shall: 
 (i) commencing with the furnishing of annual financial information for the fiscal year ending December 31,
2012, hold a quarterly conference call to discuss the quarterly and annual financial information contained in Section 6(a) not later than fifteen (15) Business Days from the time the Company furnishes such reports to the 4% Holders;

 (ii) no fewer than three (3) Business Days prior to the date of the conference call required to be held in accordance
with clause (i) above, issue a press release to the appropriate news wire services announcing the time and date of such conference call and directing the beneficial owners of, and prospective investors in, the Common Stock and securities
analysts to contact an individual at the Company (for whom contact information shall be provided in such press release) to obtain such financial information and information on how to access such conference call; and 

(iii) maintain a website to which beneficial owners of, and prospective investors in, the Common Stock and securities analysts are given
access and to which the financial information required by Section 6(a) are posted along with, as applicable, details on the time and date of the conference call required by clause (i) above and information on how to access that
conference call. 
 Section 7. Termination. This Agreement shall terminate upon the first to occur of
(a) execution of a written agreement to such effect by all parties hereto who are 4% Holders at the time of such execution, (b) upon the pricing of an Initial Public Offering or (c) the closing of a transaction that would constitute a
Change in Control. In addition, the rights and obligations of each Holder under this Agreement shall terminate as to such Holder upon the Transfer of all Common Stock owned by such Holder in accordance with this Agreement. 

  
 12 









 Section 8. Miscellaneous Provisions. 

(a) Transfer in Violation of Agreement. Any Transfer or attempted Transfer in breach of this Agreement shall be void and of no
effect. In connection with any attempted Transfer in breach of this Agreement, the Company may hold and refuse to transfer any Common Stock or any certificate therefor, in addition to and without prejudice to any and all other rights or remedies
which may be available to it or the 4% Holders. Each party to this Agreement acknowledges that a remedy at law for any breach or attempted breach of this Agreement shall be inadequate, agrees that each other party to this Agreement shall be entitled
to specific performance and injunctive and other equitable relief in case of any such breach or attempted breach and further agrees to waive (to the extent legally permissible) any legal conditions required to be met for the obtaining of any such
injunctive or other equitable relief (including posting any bond in order to obtain equitable relief). 
 (b) United States
Real Property Interest. The Common Stock is not a “United States real property interest”, as that term is defined in Section 897(c)(1)(A) of the Internal Revenue Code of 1986, as amended. The Company agrees to provide a notice
pursuant to, and complying with the requirements of, U.S. Treasury Regulations Section 1.897-2(h) within 15 days of the request for such a notice from any 4% Holder. 
 (c) No Strict Construction. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction
shall be applied against any party. 
 (d) No Third-Party Beneficiaries. Nothing in this Agreement, express or implied,
is intended or shall be construed to confer upon, or give to, any person or entity other than the parties hereto and their respective successors and assigns any remedy or claim under or by reason of this Agreement or any terms, covenants or
conditions hereof, and all of the terms, covenants, conditions, promises and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their respective successors and assigns. 

(e) Further Assurances. Each party hereto shall do and perform or cause to be done and performed all such further acts and things
and shall execute and deliver all such other agreements, certificates, instruments, and other documents as any other party hereto reasonably may request in order to carry out the provisions of this Agreement and the consummation of the transactions
contemplated hereby. 
 (f) Transfers; Successors and Assigns. No 4% Holder may Transfer shares of Common Stock unless
the Transferee first executes an Adoption Agreement in the form attached hereto as Exhibit C (each, an “Adoption Agreement”). The 4% Holder shall notify the Company immediately upon any such Transfer and shall promptly
provide a copy of the executed Adoption Agreement to the Company. This Agreement shall be binding upon the parties hereto and their respective successors and assigns and to such additional Persons that may become 4% Holders of the Company and
parties hereto for the uses and purposes set forth and referred to herein. 
 (g) Counterparts. This Agreement may be
executed in one or more counterparts, and may be delivered by means of facsimile or electronic transmission in portable document format, each of which shall be deemed to be an original and shall be binding upon the party who executed the same, but
all of such counterparts shall constitute the same agreement. The failure of any Holder to execute this Agreement does not make it invalid as against any other Holder. 

  
 13 









 (h) Governing Law. This Agreement and all disputes or controversies arising out of or
relating to this Agreement or the transactions contemplated hereby shall be governed by, and construed in accordance with, the internal laws of the State of Delaware. 
 (i) Submission to Jurisdiction. Each of the parties irrevocably agrees that any legal action or proceeding arising out of or relating to this Agreement brought by any other party or its successors
or assigns shall be brought and determined in the Court of Chancery of the State of Delaware, the courts of the United States of America for the District of Delaware and appellate courts thereof, and each of the parties hereby irrevocably submits to
the exclusive jurisdiction of the aforesaid courts for itself and with respect to its property, generally and unconditionally, with regard to any such action or proceeding arising out of or relating to this Agreement and the transactions
contemplated hereby. Each of the parties agrees not to commence any action, suit or proceeding relating thereto except in the courts described above in Delaware, other than actions in any court of competent jurisdiction to enforce any judgment,
decree or award rendered by any such court in Delaware as described herein. Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service
is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action or proceeding arising out of or relating to this Agreement or
the transactions contemplated hereby, (i) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (ii) that it or its property is exempt or immune from jurisdiction of
any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) that (A) the
suit, action or proceeding in any such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.
No course of dealing between the Company, or its subsidiaries, and the Holders (or any of them) or any delay in exercising any rights hereunder will operate as a waiver of any rights of any party to this Agreement. The failure of any party to
enforce any of the provisions of this Agreement will in no way be construed as a waiver of such provisions and will not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

 (j) Complete Agreement; Inconsistent Agreements. This Agreement and any certificates, documents, instruments and
writings delivered pursuant to it represent the complete agreement between the parties hereto as to all matters covered hereby, and supersedes any prior agreements or understandings between the parties. 

(k) Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a
particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid
provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 

(l) Amendments; Waivers. Neither this Agreement nor any provision hereof may be amended, modified, waived or supplemented in any
manner, whether by course of conduct or otherwise, except with the consent of the Company and 4% Holders consisting of the largest Holder Group and one additional Holder Group, provided that such 4% Holders represent at least a majority of the
issued and outstanding Common Stock held by the 4% Holders. Notwithstanding the foregoing, in order to effect any amendment of, modification of, waiver of or supplement to the provisions of this Agreement that 

  
 14 









 
would adversely affect an individual 4% Holder disproportionately as compared to all other 4% Holders, the Company must obtain the prior written consent of such 4% Holder. No failure or delay by
a party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or
privilege. 

  
 15 









 This Agreement is executed by the Company and by each other Person who beneficially owns
outstanding Common Stock and elects to become party to this Agreement from time to time in accordance with the provisions herein to be effective as of the date first above written.
