ONeill entitled to receive) any consideration, compensation, payments, bonuses, commissions, reimbursements, incentive payments, stock, equity interests, stock options, or benefits of any kind. Mr. ONeill further acknowledges and
agrees that Rogue Wave has paid to Mr. ONeill in full any and all wages, salary, accrued but unused vacation, floating holiday accrued but not taken, personal time off, commissions, bonuses, stock options, incentive payments and compensation
due and owing, if any, as of the Separation Date. The Parties also agree that, except as provided in paragraph 14 of this Agreement supersedes any and all prior agreements concerning the obligations of Rogue Wave to Mr. ONeill.





7.     DENIAL OF LIABILITY.The Parties acknowledge that any payment by Rogue Wave and any release by Mr. ONeill pursuant to this Agreement are made to ensure that the separation is amicable, that in making any such payment or release, Rogue Wave and Mr. ONeill
in no way admit any liability to each other and that they expressly deny any such liability.





8.     NONDISPARAGEMENT.Mr. ONeill agrees that he will not at any time disparage Rogue Wave nor any of its officers or directors to third parties in any manner likely to be harmful to
Rogue Wave, its business reputation, or the personal or business reputation of its officers, directors, shareholders and/or employees. Notwithstanding the prohibition in the preceding sentence, Mr. ONeill shall respond truthfully, accurately
and fully to any question, inquiry, or request for information when required by legal process.

in whatever form (and all copies thereof) and any and all other Rogue Wave property in Mr. ONeills possession, custody or control, including, but not limited to, financial information, customer information, customer lists, employee
lists, Rogue Wave files, notes, contracts, contracts, drawings, records, business plans and forecasts, financial information, specifications, computer-recorded information, software, tangible property, including any computer equipment, laptops,
cellular telephones, pagers, credit cards, entry cards, identification badges and keys, and any materials of any kind which contain or embody any proprietary or confidential material of Rogue Wave (and all reproductions thereof in any form including
electronic or paper). Mr. ONeill agrees that should he fail to comply with this paragraph of this Agreement, Rogue Wave may pursue any rights it has in law or in equity to recover such information, to prevent Mr. ONeills use,
disclosure, or destruction of such property, and to recover damages for Mr. ONeills retention, use, disclosure, or destruction of Rogue Wave property.





10.     CONFIDENTIALITY/NON-DISCLOSURE.Mr. ONeill acknowledges that confidentiality and
nondisclosure of the terms of this Agreement are material considerations for the Parties entering into this Agreement. Mr. ONeill acknowledges, represents, and agrees that he has not and will not discuss the terms or provisions of the
Agreement with any current or former Rogue Wave employee except the Vice President of Human Resources and the Chief Executive Officer. As such, the provisions of this Agreement shall be held in strictest confidence by Mr. ONeill and shall not
be publicized or disclosed in any manner whatsoever, including but not limited to, the print or broadcast media, any public network such as the Internet, any other outbound data program such as computer generated mail, reports or faxes, or any
source likely to result in publication or computerized access. Notwithstanding the prohibitions in this paragraph: (a) the Mr. ONeill may disclose this Agreement in confidence to his attorneys, accountants, auditors, tax preparers, and
financial advisors; and (b) Mr. ONeill may disclose this Agreement insofar as such disclosure may be necessary to enforce its terms or as otherwise required by law. Mr. ONeill agrees and acknowledges that any breach of the foregoing
provisions concerning confidentiality would cause damage to Rogue Wave in an amount that would be extremely difficult or impossible to calculate. Accordingly, Mr. ONeill agrees that, in the event of any breach by Mr. ONeill, his spouse,
attorneys, accountants, or tax advisors of the foregoing provisions, Rogue Wave shall be entitled to liquidated damages in the amount of Twenty Five Thousand Dollars ($25,000). Mr. ONeill explicitly agrees and acknowledges that this provision
with respect to liquidated damages is reasonable under the circumstances existing at the time the Agreement was made.





11.     ADEA WAIVER AND RELEASE BY MR. ONEILL.Mr. ONeill acknowledges that Mr. ONeillis
knowingly and voluntarily waiving and releasing any rights Mr. ONeillmay have under the federal Age Discrimination in Employment Act of 1967, as amended (ADEA Waiver and Release). Mr. ONeill acknowledges that the
consideration given for this ADEA Waiver and Release, provided for in paragraph 4 above, is in addition to anything of value to which Mr. ONeillwas already entitled. The parties agree and acknowledge that Mr. ONeill has been
advised by this writing, as required by the ADEA that: (a) this ADEA Waiver and Release does not apply to any claims under ADEA that may arise after the date that Mr. ONeill signs this Agreement; (b) Mr. ONeill has the right to and is
advised to consult with an attorney prior to executing this Agreement; (c) Mr. ONeill has forty-five days within which to consider this ADEA Waiver and Release (although Mr. ONeill may choose to

the execution of this Agreement to revoke Mr. ONeills ADEA Waiver and Release by sending, via certified United States mail, written notice of revocation to the attention of Rogue Wave, Attn. Vice President of Human Resources; 5500
Flatirons Parkway, Boulder, CO 80301, and (e) this Agreement will not be effective until the date upon which the revocation period has expired, which will be the eighth day after Mr. ONeill signs this Agreement, provided that the Company has
also signed this Agreement by that date. The parties acknowledge and agree that revocation by Mr. ONeill of the ADEA Waiver and Release is not effective to revoke Mr. ONeills waiver or release of any other claims pursuant to
this Agreement. The parties further agree that revocation by Mr. ONeill of the ADEA Waiver and Release shall entitle Rogue Wave to recover any and all payments made by Rogue Wave in consideration for Mr. ONeill executing and not revoking
the ADEA Waiver and Release, as articulated in paragraph 2 and to recover the costs, expenses and attorneys fees incurred in attempting to recover such payments.





12.     BUSINESS EXPENSE REIMBURSEMENT. Rogue Wave agrees to reimburse Mr. ONeill for those
reasonable business expenses he necessarily incurred in his capacity as a Rogue Wave employee prior the Separation Date to the extent such expenses are consistent with Rogue Waves policies in this regard. Mr. ONeill acknowledges and
agrees that Rogue Wave will not reimburse him for any expenses he incurred after the Separation Date. Mr. ONeill must submit the necessary documentation establishing the amount, date and reason for expenses he incurred and for which he seeks
reimbursement no later than 15 days after the Separation Date.





13.    
REFERENCES. To coordinate Rogue Waves response to any inquiries from prospective employers seeking employment references concerning Mr. ONeill, Mr. ONeill agrees to direct such prospective employers
exclusively to the Rogue Wave Vice President of Human Resources. Should the Vice President of Human Resources receive an inquiry, the Vice President (or an authorized agent acting on behalf of the Vice President) shall confirm Mr.
ONeills period of employment with Rogue Wave, the position he held, and the latest salary that he received as an employee and will state that company policy precludes the release of further information.





14.     NONDISCLOSURE OF PROPRIETARY INFORMATION
AND NON-COMPETITION AGREEMENT.Mr. ONeill agrees and acknowledges that he is bound, and will continue to be bound after the Execution Date of this Agreement, by the terms of the

covenant not to solicit Rogue Wave customers, employees, and partners. Nothing in this paragraph should be construed to narrow the obligations of Mr. ONeill imposed by any other agreement, statute, case law or other source.
