Dear Sirs/Madams:

Re: Voting Support Agreement

I, the individual whose name is set forth on the signature page attached to this letter agreement (the "Agreement"), understand that Qvantel Oy ("Purchaser" or "you") and Optiva Inc. (the "Corporation") are entering into an arrangement agreement dated as of the date hereof, as may be amended from time to time (the "Arrangement Agreement"), contemplating an arrangement (the "Arrangement") of the Corporation and you by way of a plan of arrangement pursuant to Section 192 of the Canada Business Corporations Act, pursuant to the terms of the Arrangement Agreement. I am the registered or beneficial owner, directly or indirectly, of, or have direction or control over, such number of Corporation Shares, if any (the "Subject Shares"), and such other rights to acquire Corporation Shares, if any (together with the Subject Shares, the "Subject Securities"), as set forth on the signature page attached to this Agreement. If I become the legal or beneficial owner of any additional Corporation Shares, or any additional Corporation Shares become, directly or indirectly, controlled or directed by me following the date hereof but prior to the Corporation Shareholder Meeting, I agree that such additional Corporation Shares shall be deemed to be Subject Shares for the purposes of this Agreement, and I shall abide by the terms of this Agreement in respect of such Corporation Shares.

All capitalized terms used but not otherwise defined herein shall have the respective meaning ascribed to them in the Arrangement Agreement.
I hereby covenant and agree, solely in my capacity as securityholder and not in my capacity as an officer or director of the Corporation:

(a) to cause all of the Subject Shares to be counted as present for purposes of establishing quorum at the Corporation Shareholder Meeting;
(b) to vote (or to cause to be voted) all of the Subject Securities, and any other securities of the Corporation directly or indirectly acquired by or issued to the undersigned on or after the date hereof that are beneficially owned by, or over which control or direction is exercised by, the undersigned and which are entitled to be voted at the Corporation Shareholder Meeting (including without limitation any common shares issued upon further exercise of options or other rights to purchase common shares), if any, (i) in favour of the Arrangement and any other matter necessary for the completion of the Arrangement at the Corporation Shareholder Meeting; and (ii) against any resolution proposed at the Corporation Shareholder Meeting which could in any manner, frustrate, prevent, delay or nullify the Arrangement or any of the other transactions contemplated thereby;
(c) no later than 5 Business Days prior to the proxy cut-off date for the Corporation Shareholder Meeting, to: (i) deliver or to cause to be delivered to the Corporation duly

2 -
executed proxies or voting instruction forms voting in favour of the Arrangement; or (ii) vote all of the Subject Shares electronically in favour of the Arrangement; in each case, such proxy, voting instruction forms or electronic votes not to be revoked or withdrawn without the prior written consent of the Purchaser;

(d) in response to any request from the Purchaser, confirm whether the action in clause (c) above has been taken;

(e) not to (i) exercise and shall ensure that no beneficial owner of the Subject Shares exercises, and hereby irrevocably waives to the fullest extent permitted by law, any and all rights of dissent or appraisal in respect of the Arrangement; or (ii) contest and shall ensure that no beneficial owner of the Subject Shares contests in any way the approval of the Arrangement;

(f) not to, directly or indirectly, sell, transfer, pledge or assign or agree to sell, transfer, pledge or assign any of the Subject Securities or any interest therein, without your prior written consent, except to one or more entities directly or indirectly wholly-owned or controlled by myself, other than: (i) to exercise or surrender Subject Securities in accordance with the terms and subject to the conditions of the Arrangement Agreement, (ii) to authorize the Corporation to withhold common shares that may otherwise be due to me pursuant to the exercise or settlement of Subject Securities or sell (or authorize the Corporation to sell) any common shares to fund employee withholding taxes which must be remitted with respect to the exercise or settlement of Subject Securities, or (iii) to sell Subject Shares to fund the exercise price upon the exercise or settlement of Subject Securities.

Notwithstanding any provision of this Agreement to the contrary, you hereby agree and acknowledge that I am executing this Agreement and am bound hereunder solely in my capacity as a securityholder of the Corporation and that the provisions hereof shall not be deemed or interpreted to bind me in my capacity as an officer or director of the Corporation. Nothing contained in this Agreement shall limit or affect any actions or omissions I may take in my capacity as a director or officer of the Corporation or limit or restrict in any way the exercise of my fiduciary duties as a director or officer of the Corporation including, without limitation, responding in my capacity as a director or officer of the Corporation to an Acquisition Proposal and making any determinations in that regard in the exercise of my fiduciary duties, and no such actions or omissions shall be deemed a breach of this Agreement.
I hereby represent and warrant to you as follows and acknowledge that you are relying on such representations and warranties in connection with entering into this Agreement and the Arrangement Agreement:

(a) I am the registered and/or beneficial owner of, or the person exercising control or direction over, the Subject Securities, with good and marketable title thereto free of any and all encumbrances and demands of any nature or kind whatsoever, and I have the sole right to vote or cause to be voted (in the case of Subject Shares) and sell, dispose of or transfer or cause to be sold, disposed of or transferred (in the case of transferable Subject Securities) all of the Subject Securities, subject to the express terms of the Corporation Incentive Plans and of any document evidencing the grant of any applicable Subject Securities;

(b) except for the Arrangement Agreement and this Agreement, no person has any agreement or option, or any right or privilege (whether by law, pre-emptive or contractual) capable of becoming an agreement or option for the purchase, acquisition or transfer from the

undersigned or the applicable holder of any of the Subject Securities or any interest therein or right thereto;

(c) the only securities of the Corporation beneficially owned, directly or indirectly, or over which control or direction is exercised by the undersigned on the date hereof are the Subject Securities (other than securities that are not entitled to acquire common shares in the capital of the Corporation);

(d) I have been afforded the opportunity to obtain independent legal advice and confirm by the execution of this Agreement that I have either done so or waived my right to do so in connection with the entering into of this Agreement, and that any failure on my part to seek independent legal advice shall not affect (and I shall not assert that it affects) the validity, enforceability or effect of this Agreement or the Arrangement Agreement; and

(e) this Agreement has been duly executed and delivered and is a valid and binding agreement, enforceable against me in accordance with its terms.

The representations, warranties and covenants of myself set forth herein shall survive until the termination of this Agreement.

This Agreement shall automatically terminate and be of no further force and effect upon the earliest of (i) our mutual written agreement, (ii) the Effective Time, (iii) the termination of the Arrangement Agreement in accordance with its terms or you publicly announcing that you will not be proceeding with the Arrangement, or (iv) any amendment of the Arrangement Agreement to reduce the amount of or the form of the Corporation Shareholder Consideration without my prior written consent. If this Agreement is terminated, the provisions of this Agreement will become void and of no further force or effect without liability of any party to the other parties.
This Agreement will be governed by and interpreted and enforced in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein without regard to any conflicts of law provisions.
Each party irrevocably attorns and submits to the exclusive jurisdiction of the Ontario courts situated in the City of Toronto and waives objection to the venue of any proceeding in such court or that such court provides an inconvenient forum.
The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached. It is accordingly agreed that the parties are entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, on a non-exclusive basis, in any court of the Province of Ontario having jurisdiction, this being in addition to any other remedy to which such party is entitled at law or in equity.
The parties agree to pay their own respective expenses incurred in connection with this Agreement.
The parties will, from time to time, execute and deliver all such further documents and instruments and do all such acts and things as the other party may reasonably require (at the requesting party's cost) to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.
The parties consent to the disclosure of the substance of this Agreement in any press release required by applicable laws or any circular relating to the Meetings, including the Circular, and to

the filing of this Agreement on SEDAR+ without redaction other than certain contact information set out herein. A copy of this Agreement may be provided to the directors of the Corporation. Except as required by law or applicable stock exchange requirements, I shall not make any public announcement or statement with respect to the Arrangement or this Agreement without the prior written approval of the Purchaser. Moreover, I agree to provide prior notice to the Purchaser of any public announcement relating to the Arrangement or this Agreement and agree to consult with the Purchaser prior to issuing such public announcement.

This Agreement may be executed in any number of counterparts (including counterparts by docusign or electronic copy) and all such counterparts taken together shall be deemed to constitute one and the same instrument. The parties shall be entitled to rely upon delivery of an executed electronic copy of this Agreement, and such executed electronic copy shall be legally effective to create a valid and binding agreement between the parties.
No party may assign any of their rights or obligations under this Agreement without the prior written consent of the other party.
This Agreement is entered into for the exclusive benefit of Purchaser and its successors or assigns. This Agreement is expressly not intended for the benefit of any creditor of Purchaser or any other person, and no such other person shall have any rights under this Agreement or any agreement between the parties with respect thereto.
Time is of the essence of this Agreement.
The provisions of this Agreement will be severable in the event that any of the provisions hereof are held by a court of competent jurisdiction to be invalid, void or otherwise unenforceable, and the remaining provisions will remain enforceable to the fullest extent permitted by law so as to effect the intent of the parties hereto, and shall in no way be affected, impaired or invalidated.
This Agreement may only be amended, supplemented or otherwise modified by written agreement signed by the parties hereto.
This Agreement constitutes the entire agreement between the parties pertaining to the subject matter of this Agreement.
If the foregoing is in accordance with your understanding and is agreed to by you, please signify your acceptance by executing the enclosed copies of this letter where indicated below and returning the same to the undersigned, upon which this letter as so accepted shall constitute an agreement among us.

The Shareholder and the Purchaser understand and agree that the Corporation is a party to this letter agreement (the "Agreement") solely for purposes of, and shall only be bound by and entitled to the benefits of, Sections 6, 7 and 9 thereof.

All capitalized terms used but not otherwise defined herein shall have the respective meaning ascribed to them in the Arrangement Agreement.
The Shareholder is the legal or beneficial owner of or exercises voting control or direction over, directly or indirectly, the Corporation Shares listed in Schedule "A" attached hereto (the "Subject Shares"). If the Shareholder becomes legal or beneficial owner of any additional Corporation Shares, or any additional Corporation Shares become, directly or indirectly, controlled or directed by the Shareholder following the date hereof but prior to the Corporation Shareholder Meeting, the Shareholder agrees that such additional Corporation Shares shall be deemed to be Subject Shares for purposes of this Agreement, and the Shareholder shall abide by the terms of this Agreement in respect of such Corporation Shares.
The Shareholder hereby agrees, from the date hereof until the earlier of (i) the date the Arrangement Agreement is terminated in accordance with its terms, and (ii) the termination of the Corporation Shareholder Meeting:

a. to cause all of the Subject Shares to be counted as present for purposes of establishing quorum at the Corporation Shareholder Meeting;
b. to vote (or to cause to be voted) the Subject Shares, in favour of the Arrangement and any other matter necessary for the completion of the Arrangement (including in favour of all matters recommended by management of the Corporation that could reasonably be required in furtherance of the actions contemplated thereby);

62 -

c. to vote (or to cause to be voted) all of the Subject Shares against any resolution or transaction which would in any manner, frustrate, prevent, delay or nullify the Arrangement or any of the other transactions contemplated thereby;

d. no later than 5 Business Days prior to the proxy cut-off date for the Corporation Shareholder Meeting, to: (i) deliver or to cause to be delivered to the Corporation duly executed proxies or voting instruction forms voting in favour of the Arrangement; or (ii) vote all of the Subject Shares electronically in favour of the Arrangement; in each case, such proxy, voting instruction forms or electronic votes not to be revoked or withdrawn without the prior written consent of the Purchaser;

e. in response to any request from the Purchaser, confirm whether the action in clause (d) above has been taken;

f. except as contemplated by the Arrangement Agreement, not to, directly or indirectly, sell, assign, transfer, dispose of, hypothecate, alienate, grant a security interest in, encumber, tender to any offer, transfer any economic interest (directly or indirectly) or otherwise convey any of the Subject Shares, in each case without the Purchaser’s prior written consent;

g. shall not: (i) exercise and shall ensure that no beneficial owner of the Subject Shares exercises, and hereby irrevocably waives to the fullest extent permitted by law, any and all rights of dissent or appraisal in respect of the Arrangement; or (ii) contest and shall ensure that no beneficial owner of the Subject Shares contests in any way the approval of the Arrangement;

h. except as required pursuant to this Agreement (including to give effect to clause (b) above), not to grant or agree to grant any proxy or other right to vote the Subject Shares or enter into any voting trust or pooling agreement or arrangement in respect of the Subject Shares or enter into or subject any of the Subject Shares to any other agreement, arrangement, understanding or commitment, formal or informal, with respect to or relating to the voting or tendering thereof or revoke any proxy granted pursuant to this Agreement.

i. shall not through any officer, director, employee, authorized representative or authorized agent:

i. solicit proxies or become a participant in a solicitation in opposition to or competition with the Purchaser’s proposed purchase of the Corporation Shares as contemplated by the Arrangement;

ii. assist any Person in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the Purchaser’s proposed purchase of the Corporation Shares as contemplated by the Arrangement;

iii. act jointly or in concert with others with respect to the Corporation Shares or any other securities of the Corporation for the purpose of opposing or competing with the Purchaser’s proposed purchase of Corporation Shares as contemplated by the Arrangement;

iv. solicit, initiate, knowingly encourage or otherwise facilitate (including by way of furnishing or providing copies of, access to, or disclosure of, any confidential

63 -

information of the Corporation or any of its subsidiaries or entering into any form of agreement, arrangement or understanding) any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to, an Acquisition Proposal;

v. participate in any discussions or negotiations with any Person (other than the Purchaser) regarding any inquiry, proposal or offer that constitutes or would reasonably be expected to constitute or lead to an Acquisition Proposal;

vi. accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement, arrangement or understanding regarding any Acquisition Proposal; or

vii. knowingly encourage or otherwise facilitate or encourage any effort or attempt by any other Person to do or seek to do any of the foregoing.

j. shall notify the Purchaser promptly if the Shareholder receives or otherwise becomes aware of any inquiry, proposal or offer that constitutes, or could reasonably be expected to constitute or lead to an Acquisition Proposal, or any request for copies of, access to, or disclosure of, confidential information relating to the Corporation or any of its subsidiaries, including material terms and conditions of, and the identity of the Person making, the Acquisition Proposal, inquiry, proposal, offer or request, and shall provide the Purchaser with copies of all material documents, material correspondence and other materials received from or on behalf of such Person.

Subject to the terms of this Agreement, if the Purchaser concludes that it is necessary or desirable to proceed with another form of transaction (including a take-over bid at not less than the Corporation Shareholder Consideration per Corporation Share or an amalgamation) whereby the Purchaser or one of its affiliates would effectively acquire all of the Corporation Shares for cash consideration (i) on economic terms that are equivalent to or better for the Shareholder (and its affiliates which beneficially own Corporation Shares) than those contemplated by the Arrangement Agreement, (ii) on a basis that would not likely result in a delay or time to completion beyond the earlier of (x) 120 days from the date that the Purchaser publicly announces its intention to proceed with the Alternative Transaction and (y) the Outside Date, and (iii) otherwise on terms and conditions not materially more onerous to the Shareholder than the Arrangement (an “Alternative Transaction”), the Shareholder agrees to support, and cause to be supported, the completion of such Alternative Transaction in the same manner as the Arrangement and shall otherwise fulfil its covenants contained in this Agreement in respect of such Alternative Transaction.
The Shareholder hereby represents and warrants that:

a. this Agreement has been duly executed and delivered and is a valid and binding agreement, enforceable against the Shareholder in accordance with its terms, and the performance by the Shareholder of its obligations hereunder will not constitute a violation or breach of or default under, or conflict with, any contract, commitment, agreement, understanding or arrangement of any kind to which the Shareholder will be a party and by which the Shareholder will be bound at the time of such performance;

b. as at the date hereof the Shareholder has the sole and exclusive right and authority to vote the Subject Shares and no approval of the Shareholder’s securityholders is or will be

64 -

required in order to vote the Subject Shares in favour of the Arrangement or to sell the Subject Shares to the Purchaser;

c. there is no requirement of the Shareholder to make any filing with, give any notice to, or obtain any consent, approval or waiver of, any person in connection with the execution and delivery by the Shareholder and the performance of its obligations contemplated hereby; and

d. the Shareholder has been afforded the opportunity to obtain independent legal advice and confirms by the execution of this Agreement that it has either done so or waived its right to do so in connection with the entering into of this Agreement, and that any failure on the Shareholder’s part to seek independent legal advice shall not affect (and the Shareholder shall not assert that it affects) the validity, enforceability or effect of this Agreement or the Arrangement Agreement.

The representations, warranties and covenants of the Shareholder set forth in this Section 5 shall survive until the termination of this Agreement.

The Shareholder acknowledges and agrees that the Purchaser and the Corporation will rely on this Agreement to avail themselves of the “previous arm’s length negotiations” exemption from the formal valuation requirement set forth in Section 4.4(1)(b) of Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions. In this regard:

a. the Shareholder hereby represents and warrants to the Purchaser and the Corporation that:

i. the Shareholder has participated in arm’s length negotiations with the Purchaser in connection with the Arrangement regarding the Corporation Shareholder Consideration to be received by the Corporation Shareholders (excluding the Purchaser, but including the Shareholder) from the Purchaser pursuant to the Arrangement, and the Shareholder agrees to the value and form of such Corporation Shareholder Consideration;

ii. as at the date hereof, the Shareholder beneficially owns, or exercises control or direction over, a total of 1,312,215 Corporation Shares and no other securities (including the PIK Notes); and

iii. as at the date hereof, (i) the Shareholder has full knowledge of and access to information concerning the Corporation and its securities, and (ii) any factors peculiar to the Shareholder, including non-financial factors, that were considered relevant by the Shareholder in assessing the Corporation Shareholder Consideration did not have the effect of reducing the price that would otherwise have been considered acceptable by the Shareholder; and

b. the Purchaser represents and warrants to the Shareholder that, as at the date hereof, the Purchaser does not know of any material information in respect of the Corporation or its Corporation Shares that has not been generally disclosed and if disclosed, could reasonably be expected to increase the agreed Corporation Shareholder Consideration.

The Shareholder irrevocably and unconditionally consents to (i) the details of this Agreement being set out in the news release(s) of the Purchaser and the Corporation with respect to the Arrangement and in the Circular, and (ii) a form of this Agreement being made publicly available, including by

65 -

filing on SEDAR+. Except with respect to the foregoing, each of the Purchaser, the Corporation and the Shareholder shall consult with each other before making any public disclosure or announcement of or pertaining to this Agreement, and any such disclosure or announcement shall be mutually satisfactory to the parties hereto, acting reasonably; provided that the foregoing shall not apply to any disclosure or announcement pertaining to this Agreement which a party is advised by legal counsel is required to be made by applicable laws, stock exchange rules or policies of regulatory authorities having jurisdiction and which the other parties after reasonable notice will not consent to.

This Agreement shall terminate and be of no further force and effect upon the earlier of (a) the termination of the Arrangement Agreement in accordance with its terms, (b) the Board recommending a Superior Proposal and/or authorizing the Corporation to accept, approve or enter into a definitive agreement in respect of a Superior Proposal, (c) the amendment of the Arrangement Agreement to change the amount or form of Corporation Shareholder Consideration (other than to increase the total consideration per Corporation Share or add additional consideration) or in any other manner adverse to the Shareholder, and (d) the Outside Date.
Each of the Purchaser and the Corporation agrees to use commercially reasonable efforts to complete the Arrangement on or before December 31, 2025.
This Agreement shall be governed by and construed in accordance with the laws of the Province of Ontario and the laws of Canada applicable therein, and the parties hereto irrevocably attorn to the jurisdiction of the Ontario courts situated in the City of Toronto and waive objection to the venue of any proceeding in such court or that such court provides an inconvenient forum. This Agreement may be executed in any number of counterparts (including counterparts by docusign or other electronic copy) and all such counterparts taken together shall be deemed to constitute one and the same instrument.
If the foregoing is in accordance with your understanding and is agreed to by each of you, please signify your acceptance by the execution of the enclosed copies of this Agreement where indicated below by an authorized signatory and return the same to the Shareholder, upon which this Agreement as so accepted shall constitute an agreement among the Purchaser, the Corporation and the Shareholder.

Subject to the terms of this Agreement, if the Purchaser concludes that it is necessary or desirable to proceed with another form of transaction (including a take-over bid at not less than the Corporation Shareholder Consideration per Corporation Share or an amalgamation) whereby the Purchaser or one of its affiliates would effectively acquire all of the Corporation Shares (i) on economic terms that are equivalent to or better for the Securityholder (and its affiliates which beneficially own Corporation Shares and/or the PIK Notes) than those contemplated by the Arrangement Agreement, (ii) on a basis that would not likely result in a delay or time to completion beyond the earlier of (x) 120 days from the date that the Purchaser publicly announces its intention to proceed with the Alternative Transaction and (y) the Outside Date, and (iii) otherwise on terms and conditions not materially more onerous to the Securityholder than the Arrangement (an “Alternative Transaction”), the Securityholder agrees to support, and cause to be supported, the completion of such Alternative Transaction in the same manner as the Arrangement and shall otherwise fulfil its covenants contained in this Agreement in respect of such Alternative Transaction.
The Securityholder hereby represents and warrants that:

a. this Agreement has been duly executed and delivered and is a valid and binding agreement, enforceable against the Securityholder in accordance with its terms, and the performance by the Securityholder of its obligations hereunder will not constitute a violation or breach of or default under, or conflict with, any contract, commitment, agreement, understanding or arrangement of any kind to which the Securityholder will be a party and by which the Securityholder will be bound at the time of such performance;

b. as at the date hereof the Securityholder has the sole and exclusive right and authority to vote (or provide consent in respect of) the Subject Securities and no approval of the Securityholder’s securityholders is or will be required in order to vote (or provide consent in respect of) the Subject Securities in favour of the Arrangement or to sell the Subject Securities to the Purchaser;

c. there is no requirement of the Securityholder to make any filing with, give any notice to, or obtain any consent, approval or waiver of, any person in connection with the execution and delivery by the Securityholder and the performance of its obligations contemplated hereby;

d. the Securityholder has been afforded the opportunity to obtain independent legal advice and confirms by the execution of this Agreement that it has either done so or waived its right to do so in connection with the entering into of this Agreement, and that any failure

79 -
on the Securityholder’s part to seek independent legal advice shall not affect (and the Securityholder shall not assert that it affects) the validity, enforceability or effect of this Agreement or the Arrangement Agreement.

The representations, warranties and covenants of the Securityholder set forth in this Section 5 shall survive until the termination of this Agreement.

The Securityholder irrevocably and unconditionally consents to (i) the details of this Agreement being set out in the news release(s) of the Purchaser and the Corporation with respect to the Arrangement and in the Circular, and (ii) a form of this Agreement being made publicly available, including by filing on SEDAR+. Except with respect to the foregoing, each of the Purchaser, the Corporation and the Securityholder shall consult with each other before making any public disclosure or announcement of or pertaining to this Agreement, and any such disclosure or announcement shall be mutually satisfactory to the parties hereto, acting reasonably; provided that the foregoing shall not apply to any disclosure or announcement pertaining to this Agreement which a party is advised by legal counsel is required to be made by applicable laws, stock exchange rules or policies of regulatory authorities having jurisdiction and which the other parties after reasonable notice will not consent to.
This Agreement shall terminate upon the Effective Date or the date that is 10 days following the Outside Date and may be terminated at any time by (i) notice in writing by the Purchaser to the Securityholder, or (ii) the mutual agreement in writing of the Purchaser and the Securityholder. This Agreement may be earlier terminated by the Securityholder upon an amendment of the Arrangement Agreement (i) to change the amount or the form of Corporation Shareholder Consideration or Noteholder Consideration (other than to increase the aggregate Consideration payable to the Corporation Shareholders or Noteholders) (ii) to extend the Outside Date under the Arrangement Agreement beyond March 31, 2026, or (iii) in any other manner adverse to the Securityholder, in each case without the prior written of the Securityholder.
This Agreement shall be governed by and construed in accordance with the laws of the Province of Ontario and the laws of Canada applicable therein, and the parties hereto irrevocably attorn to the jurisdiction of the Ontario courts situated in the City of Toronto and waive objection to the venue of any proceeding in such court or that such court provides an inconvenient forum. This Agreement may be executed in any number of counterparts (including counterparts by docusign or other electronic copy) and all such counterparts taken together shall be deemed to constitute one and the same instrument.
The parties to this Agreement agree that irreparable harm would occur for which money damages would not be an adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties to this Agreement shall be entitled to injunctive and other equitable relief to prevent breaches of this Agreement and to enforce compliance with the terms of this Agreement, without any requirement for the securing or posting a bond or other security in connection with the obtaining of any such injunctive or other equitable relief, this being in addition to any other remedies to which the parties to this Agreement may be entitled at law or in equity, and no party shall object to the granting of injunctive or other equitable relief on the basis that there exists an adequate remedy at law or in equity.
If the foregoing is in accordance with your understanding and is agreed to by each of you, please signify your acceptance by the execution of the enclosed copies of this Agreement where indicated
