**Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.**

On April 7, 2026, the Board of Directors (the "Board") of ATN International, Inc. (the "Company") announced that Naji N. Khoury has been appointed (the "Appointment") President and Chief Executive Officer ("CEO") to be effective as of April 20, 2026 (the "Effective Date").

Mr. Khoury, 59, previously served as the CEO of Liberty Communications Puerto Rico from 2012 to 2024 and as a member of the Executive Leadership Team of Liberty Latin America Ltd. ("Liberty") from 2018 to 2024. Mr. Khoury joined Liberty in 2010 as the Managing Director of Liberty Cable Puerto Rico. Prior to Liberty, Mr. Khoury spent a decade holding several leadership positions at Centennial Communications, most recently serving as its Senior Vice President of Marketing, Business Development and Customer Service. Mr. Khoury earned a Master's degree in engineering from The Johns Hopkins University and a Bachelor of Science degree in electrical engineering from Syracuse University.

There are no arrangements or understandings between Mr. Khoury and any other person pursuant to which Mr. Khoury was appointed principal executive officer. Mr. Khoury does not have any direct or indirect material interests in any transaction required to be disclosed pursuant to Item 404(a) of Regulation S-K, nor does he have any family relationships with any of the Company's directors or executive officers.

In connection with the Appointment, the Board approved Mr. Khoury's compensation, as set forth in that certain Offer of Employment Letter, dated as of April 1, 2026 (the "Offer Letter"). Beginning on the Effective Date, Mr. Khoury will receive an annual base salary of $600,000 for his services as President and CEO and will be eligible to receive an annual cash performance bonus of up to 150% of his base salary (pro-rated for calendar year 2026), with the actual amount of such bonus to be determined by the Board based upon, among other things, achievement of the corporate and individual performance objectives approved by the Compensation Committee of the Board (the "Compensation Committee"). Notwithstanding the foregoing, pursuant to the Offer Letter, Mr. Khoury's 2026 annual cash performance bonus will not be less than 60% nor more than 100% of his pro-rated target bonus and is subject to his continued employment through the payout date.

The Offer Letter also provides that Mr. Khoury will be eligible to receive annual equity awards. For 2026, he will receive an equity award (the "2026 Equity Award") with a grant date fair value of $2,000,000, based upon the average closing price of the Company's common stock for the 20 trading days prior to and including the Friday before grant approval. The 2026 Equity Award will consist of 50% time-based restricted stock units ("RSUs") and 50% performance-based performance stock units ("PSUs"), with the RSUs vesting in equal annual installments on each of the first, second, third, and fourth anniversaries of the grant date and the PSUs vesting based upon the Company's total shareholder return relative to the Russell 2000 measured over a three-year performance period .

Pursuant to the Offer Letter, Mr. Khoury will also be eligible to receive an aggregate of $135,000 (the "Relocation Payment") to cover certain relocation and temporary housing expenses. The Relocation Payment will be paid in three installments, provided that Mr. Khoury remains employed by the Company on the applicable payment date, and is subject to recoupment under certain circumstances as set forth in the Offer Letter.

Mr. Khoury will also be eligible to participate in all benefit plans of the Company that are generally available to the Company's senior executives, and will be subject to the Company's Executive Compensation Recoupment Policy.

The Company and Mr. Khoury also entered into the Company's standard form of Restrictive Covenants Agreement, which includes customary confidentiality, non-solicitation, and non-competition restrictive covenants in favor of the Company (the "Restrictive Covenants Agreement"). It is anticipated that the Company and Mr. Khoury also will enter into an Executive Severance Agreement on the Company's standard terms (the "Severance Agreement"). In accordance with Instruction 2 to Item 5.02 of Form 8-K, the Company intends to file an amendment to this Current Report on Form 8-K if and when the Severance Agreement is finalized and executed.

Brad Martin, the Company's current CEO, ceased to serve as the Company's principal executive officer and as a member of the Board, effective as of April 6, 2026. The Board intends to nominate Mr. Khoury as a director, effective upon election by stockholders at its upcoming Annual General meeting on June 16, 2026. On April 6, 2026, the Company and Mr. Martin entered into that certain Consulting Services Agreement (the "Consulting Agreement"), pursuant to which Mr. Martin has agreed to provide certain support services in connection with the leadership transition during the period beginning April 7, 2026 and ending May 31, 2026. In consideration of such services, the Company will pay Mr. Martin $25,000 in two equal installments on April 30, 2026 and May 31, 2026. For the avoidance of doubt, the payments pursuant to the Consulting Agreement are in addition to, and not in lieu of, any benefits that Mr. Martin may be entitled to pursuant to that certain Executive Severance Agreement, by and between the Company and Mr. Martin, effective January 1, 2024, subject to his timely execution and non-revocation of a release and waiver of claims in favor of the Company. The Company thanks Mr. Martin for his many years of service.

The foregoing summaries of the Offer Letter, the Restrictive Covenants Agreement, and the Consulting Agreement do not purport to be complete and are qualified in their entireties by reference to the full texts of the Offer Letter, the Restrictive Covenants Agreement, and the Consulting Agreement, copies of which are filed as Exhibits 10.1, 10.2, and 10.3 hereto, respectively, and are incorporated herein by reference.

 **Item 7.01 Regulation FD Disclosure.**

On April 7, 2026, the Company issued a press release regarding the Appointment. A copy of the press release is furnished herewith as Exhibit 99.1 and incorporated herein by reference.

Exhibit 99.1 is furnished and shall not be deemed to be "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing made by the Company under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Naji N. Khoury

**RE: Offer of Employment**

Dear Naji,

We are delighted to offer you a position with ATN International, Inc. ("ATN" or "Company"). This letter confirms our offer and includes details on both the financial arrangements and the Company's benefit programs.

Our vision at ATN looks to a future where all people and communities, regardless of geographic or economic circumstance, will have access to the resources and connections of the global data ecosystem. The vision and mission of ATN are important to both the employees and the Board of Directors, and help drive a culture focused on delivering for customers. The Board of Directors believes we can deliver on this promise while at the same time delivering attractive returns to our stockholders and accessing capital markets as we look to grow. In the Board's discussions with you, we are convinced that you are the right person to lead ATN through the next phase of its development.

**Your Title, Compensation & Benefits**

We have agreed that your start date will be April 20, 2026, and that you will report exclusively to the ATN Board of Directors (the "Board") as **President and Chief Executive Officer** ("CEO") and will have duties and responsibilities commensurate with such position. We will nominate you to serve as a member of the Board as long as you serve as the CEO of the Company.

Your annualized base salary will be $600,000, or $23,076.92 paid bi-weekly. This salary will be subject to adjustment pursuant to the Company's employee compensation policies and reduced for applicable taxes and deductions.

You will be eligible to earn an annual cash performance bonus, targeted at 150% of your base salary (pro-rated for calendar year 2026), pursuant to the Company's annual bonus program for senior level executives, including its Compensation Recoupment Policy. The amount of any bonus earned will be based on the terms of the annual bonus program, including the corporate and individual performance objectives approved by the Compensation Committee ("Compensation Committee") of the Board. The determination of whether you have achieved such objectives, and the amount of any bonus payment will be at the sole discretion of the Board; provided that, we agree that your 2026 annual cash performance bonus will not be less than 60% or more than 100% of your target bonus, in either case pro-rated for the portion of the 2026 calendar year you are employed with ATN. Any bonus is not earned until the time of payment, and you must be an employee of the Company in good standing at the time any bonus is paid (including the 2026 annual cash performance bonus) to be eligible to receive it.

You also will be eligible for annual ATN equity grants as and when considered for other executives, which have typically been determined and granted towards the end of the first quarter of each calendar year. For 2026, the Compensation Committee will approve the issuance of an equity grant to you on or shortly after your employment start date with a grant date value of no less than $2,000,000, which is determined based on the average closing price of the Company's common stock for the twenty trading days prior to and including the Friday before the grant approval. Half of this grant will consist of time-based Restricted Stock Units (RSUs) and half of performance-based Performance Stock Units (PSUs). The time-based RSUs will vest in equal annual installments on each of the first, second, third, and fourth anniversaries of the grant date and are payable in shares of ATN Common Stock. The PSUs vest over a three-year performance period, based on applicable performance objectives determined by the Compensation Committee, currently anticipated to be ATN's TSR compared to the TSR for the Russell 2000, and are payable in shares of ATN Common Stock. In each case, any grant you may receive will be subject to the terms and conditions of our equity plan, the forms of equity award approved by the Compensation Committee, and the Company's Compensation Recoupment policy (a copy of which is attached to this letter).

You will be eligible for ATN's standard executive severance benefits after your start date, on substantially the same terms and conditions as applicable to other senior executives (the "Executive Severance Agreement"). Notwithstanding any term to the contrary in the Executive Severance Agreement (or otherwise), Good Reason shall also include a requirement that you report to a person other than the Board. We will provide you with the Executive Severance Agreement under separate cover.

In view of your plan to reside primarily in the Beverly or Boston area while serving in this role, you will be eligible to receive an aggregate amount of $135,000 (the "Relocation Payment") to cover certain of your relocation and temporary housing expenses incurred in connection with your commencement of employment with ATN. The Relocation Payment will be paid in three installments, and, in order to receive any installment, you must be employed by the Company on the applicable payment date. The first installment will be equal to $65,000 and will be paid to you as soon as practicable following your start date; the second installment will be equal to $35,000 and will be paid to you as soon as practicable following your completion of two months of employment, and the third installment will be equal to $35,000 and will be paid to you as soon as practicable following your completion of three months of employment. Each installment of the Relocation Payment will be reduced by applicable taxes and deductions. If your employment is terminated by ATN for Cause or if you resign other than for Good Reason prior to the first anniversary of your start date, you shall be required to repay the Relocation Payment in accordance with the following: if your employment terminates within six months following your start date, you shall repay all installments of the Relocation Payment previously paid to you and if your employment terminates at least six months following your start date but prior to the first anniversary of your start date, you shall be required to repay half of the Relocation Payment. Any repayment shall occur within 30 days following your termination date. For purposes of the Relocation Payment, "Cause" and "Good Reason" will have the meaning set forth in your Executive Severance Agreement.

ATN is proud of the benefits we offer to our employees. In designing the program, we believe we have created a flexible mix of benefits intended to meet your needs and those of your family. You will be eligible to participate in the Company's medical, dental, life and disability insurance plans the first of the month following your date of hire. Additionally, you will be eligible to participate in our 401(k) plan the 1st of the month following 30 days of employment. At such time as you become eligible for these benefits, you will receive enrollment information. You will accrue Earned Time Off (ETO) at the rate of 7.69 hours per bi-weekly pay period (200 hours annualized). Details of all the benefit plans, enrollment and employee contributions will be sent separately. The Company reserves the right to modify, suspend or discontinue any benefit at any time, without advance notice, and in its sole discretion.

**Contingencies**

This offer of employment is contingent upon your providing satisfactory documentation to ATN concerning your employment eligibility as required by Congress under applicable immigration laws. This documentation must be received by the Company within three (3) business days of your start date. ATN has completed a satisfactory investigation of your background by the time of your execution of this offer letter. You agree to release ATN, its employees and agents and any individuals who may provide the Company with information regarding your background and references from any liability in connection with this investigation.

An electronic copy of the current Employee Handbook will be provided to you after your start date and will require you to sign and return a form acknowledging you have read and understood the Company's policies and have been provided the opportunity to address any questions or concerns you may have. During your employment with the Company, you will be required to follow all the Company's internal policies and to always conduct your business activities in accordance with the highest legal, ethical, and professional standards.

This offer of employment is also contingent upon your signing the Restrictive Covenants Agreement attached as Exhibit A, which includes provisions designed to protect the Company's confidential and proprietary information and trade secrets, including non-solicitation and non-competition restrictions.

**At-Will Employment Relationship**

If you accept this offer, you will be an employee-at-will, which means that either you or the Company are free to terminate the employment relationship at any time with or without cause. The Company is not bound to follow any policy, procedure, or process in connection with employee discipline, employment termination or otherwise. Should you or the Company terminate your employment for any reason at any time during the calendar year, you will be entitled to receive only the pro rata portion of your base salary through the date of your termination, along with any other compensation or vested benefits to which you are entitled by law or under the terms of the Company's compensation and benefit plans that are then in effect.

**Statement Regarding Obligations to Former Employers and Other Third Parties**

As a further condition of your employment with the Company, you hereby represent that you are not presently under, and will not become subject to, any obligation to any person or entity that is inconsistent or in conflict with your employment with the Company or which would prevent, limit, or impair in any way your performance of your duties to the Company. Specifically, you represent that you have not brought with you any confidential or proprietary information of any former employer or other third party, and you are not subject to any agreement with or obligation to a former employer or other third party that would prohibit your employment by the Company or otherwise limit or impair in any way your performance of your duties to the Company.

**Interpretation, Amendment and Enforcement**

This offer letter, together with the policies and any exhibit referenced herein, contains our entire understanding regarding the terms and conditions of your employment and supersedes any prior statements regarding your employment made to you at any time by any representative of the Company. Your signature acknowledges your understanding that your employment with the Company is at-will, as described above, and that neither this letter nor anything referenced herein, nor any Company practice, other oral or written policies or statements of the Company or its agents, shall create an employment contract, guarantee a definite term of employment, or otherwise modify in any way the agreement and understanding that employment with the Company is at-will. No representative of the Company, except for the General Counsel and/or Head of Human Resources, has any authority to enter into any agreement contrary to the foregoing. By accepting this offer of employment, you agree to all terms outlined in this letter, and you also certify that you are not under any legal or contractual obligation that would prevent or restrict you from fully performing any of your responsibilities at ATN.

**Additional Provisions**

The Company will provide you with an indemnification agreement consistent with the terms provided to other directors and officers of the Company.

If the foregoing offer is acceptable to you, please accept by signing this letter agreement no later than April 1, 2026. If we do not hear from you by then, this offer will become null and void. We discussed a start date of Monday, April 20, 2026 ("Start Date"), and we should discuss the details around that, including public and internal communications prior to that time.

Along with my fellow members of ATN's Board of Directors, I look forward to working with you and I am excited to have you lead ATN towards a bright future.

## Exhibit 10.2

**Exhibit 10.2**

**<u>Restrictive Covenants Agreement</u>**

This Restrictive Covenants Agreement (the "Agreement"), dated as of April 1, 2026 and effective as of April 20, 2026 (the "Effective Date"), is made and entered by and between ATN International, Inc., a Delaware corporation ("ATN" or the "Company"), and Naji N. Khoury (the "Employee"). In consideration and as a condition of Employee's employment by ATN, and the compensation now and hereafter paid to Employee, in addition to the other consideration specified herein, Employee hereby agrees to the terms of this Agreement as follows:

1. <u>Confidentiality</u>. The Employee hereby covenants and agrees that at all times while employed by the Company and thereafter, he or she will not disclose to any person not employed by the Company, or use for any purpose other than in furtherance of his or her duties to the Company, any Confidential Information (as defined below) of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) For
 purposes of this Agreement, the term "Confidential Information" will include
 all information of any nature and in any form that is owned by the Company and that is not
 publicly available (other than by the Employee's breach of this Agreement) or generally
 known to persons engaged in businesses similar or related to those of the Company. Confidential
 Information includes, without limitation, information regarding the Company's financial
 matters, customers, employees, industry contracts, strategic business plans, product development
 (or other proprietary product data), marketing plans, consulting solutions and processes,
 and all other secrets and all other information of a confidential and proprietary nature.
 For purposes of the preceding two sentences, the term "Company" also includes
 any subsidiary of the Company. The Employee understands and acknowledges that the above list
 is not exhaustive, and that Confidential Information also includes other information that
 is marked or otherwise identified as confidential, or that would otherwise appear to a reasonable
 person to be confidential in the context and circumstances in which the information is known
 or used. The Employee understands and agrees that any Confidential Information developed
 by the Employee in the course of his or her employment by the Company shall be subject to
 the terms and conditions of this Agreement as if the Company furnished the same Confidential
 Information to the Employee in the first instance. The foregoing obligations imposed by this
 Section 1 will not apply (i) in the course of the business of and for the benefit of the
 Company as required in the performance of any of the Employee's duties to the Company
 (with the prior consent of an authorized officer acting on behalf of the Company in each
 instance), (ii) if such Confidential Information has become, through no fault of the Employee,
 generally known to the public, or (iii) if the Employee is required by law to make disclosure
 (after giving the Company notice and an opportunity to contest such requirement).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Nothing
 in this Agreement is intended to nor shall it limit or prohibit the Employee, or waive any
 right on his or her part, to initiate or engage in communication with, respond to any inquiry
 from, or otherwise provide information to, any federal or state regulatory, self-regulatory,
 or enforcement agency or authority regarding possible violations of federal or state law
 or regulation including under the whistleblower provisions of federal or state law or regulation.
 The Employee is advised that federal law provides that an individual shall not be held criminally
 or civilly liable under any federal or state trade secret law for the disclosure of a trade
 secret under either of the following conditions (i) where the disclosure is made (A) in confidence
 to a federal, state, or local government official, either directly or indirectly, or to an
 attorney; and (B) solely for the purpose of reporting or investigating a suspected violation
 of law, or (ii) where the disclosure is made in a complaint or other document filed in a
 lawsuit or other proceeding, if such filing is made under seal. Federal law also provides
 that an individual who files a lawsuit for retaliation by an employer for reporting a suspected
 violation of law may disclose the trade secret to the attorney of the individual and use
 the trade secret information in the court proceeding, if the individual files any document
 containing the trade secret under seal and does not disclose the trade secret, except pursuant
 to court order.

2. <u>Duty of Loyalty.</u> During the term of the Employee's employment by the Company, Employee will comply with all policies and rules that may from time to time be established by the Company, and will not engage directly or indirectly in any business or enterprise or activity that (a) is in any way competitive or conflicting with the interests or business of the Company; (b) occupies the Employee's attention so as to interfere with the proper and efficient performance of the Employee's duties for the Company; or (c) interferes with the independent exercise of the Employee's judgment in the Company's best interests. The Employee will comply with the Company's policies regarding disclosure and approval of work outside of the Company, as those policies are amended and in effect from time to time. In addition, in consideration of the Employee's employment by the Company, the Employee recognizes that the Employee owes a duty of loyalty to the Company and agrees that the Employee will not take personal advantage (whether directly or indirectly through family members or affiliates) of any business opportunity which is in the same or similar line of business as that engaged in by the Company. The Employee understands and agrees that the Employee is required to devote the Employee's full time and use the Employee's best efforts in the course of the Employee's employment with the Company and to act at all times in the best interests of the Company.

3. <u>Covenants Not to Compete and Not to Solicit.</u> 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Covenant Not to Compete.</u> To protect the Company's legitimate business interests as described
 herein, including its Confidential Information and goodwill, during the term of the Employee's
 employment with the Company and for the twelve (12) months thereafter, the Employee agrees
 and covenants not to engage in any activities or services in the United States and the Caribbean
 that (i) are similar to the activities and services the Employee performed or managed for
 the Company at any time during the last two years of employment with the Company, or (ii)
 may reasonably require the Employee to use or disclose Confidential Information of the Company.
 The Employee acknowledges that the geographic scope of this restriction is reasonable and
 necessary given the geographic scope of the Employee's work for the Company. In the
 event that the Employee breaches his or her fiduciary duty to the Company or unlawfully takes
 property belonging to the Company, the duration of the restrictions in this Section 3(a)
 shall be extended to two (2) years from the date of cessation of employment. The Employee
 and the Company agree that the equity grant the Company is issuing the Employee on or shortly
 after his employment start date, in addition to the Relocation Payment he is eligible to
 receive, constitute mutually-agreed upon consideration for the Employee's post-employment
 covenant in this Section 3(a).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Non-solicitation of Employees.</u> The Employee understands and acknowledges that the Company has expended
 and continues to expend significant time and expense in recruiting and training its employees
 and that the loss of employees would cause significant and irreparable harm to the Company.
 The Employee agrees and covenants not to directly or indirectly solicit, hire, recruit, attempt
 to hire or recruit, or induce the termination of employment of any employee of the Company
 during the term of the Employee's employment with the Company and for the twelve (12)
 months thereafter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Non-solicitation of Customers.</u> The Employee understands and acknowledges that the Company
 has expended and continues to expend significant time and expense in developing customer
 relationships, customer information and goodwill, and that because of the Employee's
 experience with and relationship to the Company, the Employee has had access to and learned
 about much or all of the Company 's customer information. For purposes of this clause,
 "customer information" includes, but is not limited to, names, phone numbers,
 addresses, e-mail addresses, order history, order preferences, chain of command, pricing
 information and other information identifying facts and circumstances specific to the customer.
 The Employee understands and acknowledges that loss of customer relationships, customer information
 and/or goodwill will cause significant and irreparable harm to the Company.

The Employee agrees and covenants, during the term of the Employee's employment with the Company and for the twelve (12) months thereafter, not to directly or indirectly solicit, transact business with, or contact (including but not limited to by e-mail, regular mail, express mail, telephone, or instant message) or attempt to contact the Company's current, former or prospective customers for purposes of offering or accepting goods or services similar to or competitive with those offered by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Interpretation.</u> <u> </u> The covenants contained in this Section 3 are intended to
 be construed as a series of separate covenants. If, in any judicial proceeding, the court
 shall refuse to enforce any of the separate covenants (or any part thereof), then such unenforceable
 covenant (or such part) shall be deemed to be eliminated from this Agreement for the purpose
 of those proceedings to the extent necessary to permit the remaining separate covenants (or
 portions thereof) to be enforced.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) <u>Reasonableness.</u> The Employee hereby acknowledges and agrees that the foregoing restrictions in Section 3
 are reasonable, proper and necessitated by the legitimate business interests of the Company
 and will not prevent the Employee from earning a living or pursuing the Employee's
 career. In the event that the provisions of this Section 3 shall ever be deemed to exceed
 the time, scope or geographic limitations permitted by applicable laws, then such provisions
 shall be reformed to the maximum time, scope or geographic limitations, as the case may be,
 permitted by applicable laws.

4. <u>Remedies.</u> In the event of a breach or threatened breach by the Employee of any of the provisions of this Agreement, the Employee hereby consents and agrees that the Company shall be entitled, in addition to other available remedies, to a temporary or permanent injunction or other equitable relief against such breach or threatened breach from any court of competent jurisdiction, without the necessity of showing any actual damages or that money damages would not afford an adequate remedy, and without the necessity of posting any bond or other security. The aforementioned equitable relief shall be in addition to, not in lieu of, legal remedies, monetary damages or other available forms of relief.

5. <u>Miscellaneous.</u> 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) This
 Agreement is binding upon and inures to the benefit of the Company and any successor to the
 Company, including without limitation any persons acquiring directly or indirectly all or
 substantially all of the business or assets of the Company whether by purchase, merger, consolidation,
 reorganization or otherwise (and such successor will thereafter be deemed the "Company"
 for the purposes of this Agreement).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The
 validity, interpretation, construction and performance of this Agreement will be governed
 by and construed in accordance with the substantive laws of the Commonwealth of Massachusetts,
 without giving effect to the principles of conflict of laws. The parties hereby expressly
 consent to the personal jurisdiction of the Business Litigation Session of the Suffolk County
 Superior Court of the Commonwealth of Massachusetts for any lawsuit arising from or related
 to this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If
 any provision of this Agreement or the application of any provision hereof to any person
 or circumstances is held by a court of competent jurisdiction to be invalid, unenforceable
 or otherwise illegal, the remainder of this Agreement and the application of such provision
 to any other person or circumstances will not be affected, and the provision so held to be
 invalid, unenforceable or otherwise illegal will be reformed to the extent (and only to the
 extent) necessary to make it enforceable, valid or legal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) No
 provision of this Agreement may be modified, waived or discharged unless such waiver, modification
 or discharge is agreed to in writing signed by the Employee and the Company. No waiver by
 either party hereto at any time of any breach by the other party hereto or compliance with
 any condition or provision of this Agreement to be performed by such other party will be
 deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior
 or subsequent time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) This
 Agreement may be executed in one or more counterparts, each of which will be deemed to be
 an original but all of which together will constitute one and the same agreement.

6. <u>Acknowledgments.</u> THE EMPLOYEE ACKNOWLEDGES AND AGREES THAT THE EMPLOYEE HAS FULLY READ, UNDERSTANDS AND VOLUNTARILY ENTERS INTO THIS AGREEMENT. THE EMPLOYEE ACKNOWLEDGES AND AGREES THAT HE/SHE HAS A RIGHT TO CONSULT WITH AN ATTORNEY OF HIS OR HER CHOICE BEFORE SIGNING THIS AGREEMENT AND THAT HE/SHE HAS HAD AN OPPORTUNITY TO ASK QUESTIONS AND CONSULT WITH AN ATTORNEY OF HIS OR HER CHOICE BEFORE SIGNING THIS AGREEMENT.

If such protective order or other remedy is not obtained prior to the date that the Consultant or his Representative is compelled to disclose any of the Confidential Information, or the Company or such Third Party waives compliance with the provisions hereof, the Consultant or his Representative will furnish only that portion of the Confidential Information which he is legally required to so furnish and use reasonable efforts to obtain assurance that confidential treatment will be accorded such Confidential Information. Notwithstanding anything herein to the contrary, nothing in this agreement shall (i) prohibit the consultant from making reports of possible violations of federal law or regulation to any governmental agency or entity in accordance with the provisions of and rules promulgated under Section 21F of the United States Securities Exchange Act of 1934 or Section 806 of the United States Sarbanes-Oxley Act of 2002, or of any other whistleblower protection provisions of local, state or federal law or regulation, or (ii) require notification or prior approval by the Company of any reporting described in clause (i).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.4 Upon the Company's request or in any event upon completion of the Services, Consultant will return to the Company all notes, data, documents, media and other items containing, or relating in any way to the Confidential Information or the Results (as defined below) and any copies in Consultant's possession or control.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.5 Consultant hereby acknowledges that he acquires no rights in or to any of the Confidential Information under this Agreement apart from the rights set forth in this Section 4.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.6 Consultant agrees to indemnify and hold harmless the Company and ATN from and against any and all claims, losses, costs, liabilities, damages and expenses (including, but not limited to, reasonable attorneys' fees) arising out of or in connection with any breach by Consultant or any of his Representatives of this Section 4.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.7 Notwithstanding anything herein to the contrary, the confidentiality and nondisclosure obligations of the parties set forth in this Agreement will survive the expiration or termination of this Agreement.
