(d)all claims arising under the Employment Agreement.
2.ADEA (Age) Waiver:  Shandell acknowledges and agrees that he is hereby waiving
and releasing any age claims or rights he may have under the Age Discrimination
in Employment Act of 1967, as amended (“ADEA”).  In connection with this ADEA
release, he agrees that (i) he is hereby entering into this ADEA waiver
knowingly and voluntarily, (ii) the ADEA waiver does not apply to any rights or
claims that may arise under the ADEA after the date he executes this Agreement,
(iii) the consideration given for the release of the ADEA claims is in addition
to anything of value to which he was already entitled, and (iv) he has been
advised by this writing that:
(a)he should consult with an attorney prior to executing this Agreement;
(b)he has twenty-one (21) days from receipt of this Agreement to consider
whether to execute this Agreement and release any age claim under the ADEA.  If
Shandell chooses to execute this Agreement before the 21-day period has elapsed,
he does so knowingly and voluntarily;
(c)he has seven (7) days following his execution of this Agreement to revoke his
acceptance by notifying in writing, Dan Dischner, Associate Vice President of

(d)the effective date of this Agreement as used herein shall be the eighth day

irrevocable (the “Effective Date”).
3.Shandell understands, agrees, and expressly acknowledges that this Agreement
is a full and final release of the Company and the Released Parties to include,
without limitations, all claims described in this Paragraph B, whether known and
unknown, suspected or unsuspected, and this Agreement contemplates the
extinction of all such claims, including claims for attorneys’ fees and costs.
 Shandell is hereby advised of California Civil Code Section 1542, which
provides, “A general release does not extend to claims that the creditor or
releasing party does not know or suspect to exist in his or her favor at the
time of executing the release and that, if known by him or her, would have
materially affected his or her settlement with the debtor or released party.”
Shandell knowingly and expressly waives any and all rights or benefits which he
has, had or may have against the Company and Released Parties pursuant to
Section 1542 or any similar law.  Shandell is aware that he may hereafter
discover claims or facts in addition to or different from those he now knows or
believes to exist with respect to the subject matter of this Agreement which if
known to him now may have affected his decision to enter into this Agreement;
however, Shandell hereby settles and releases all of the claims which he had,
has or may have against the Company and the other Released Parties
notwithstanding such additional or different facts.

C.NON-DISPARAGEMENT
1.Shandell acknowledges and agrees that he will continue to be bound by Sections
8 and Sections 9 of the Employment Agreement (Confidential Information and
Nonsolicitation Covenant).

The parties mutually agree not to make or cause any other person or entity to
make, any disparaging statements or generate any publicity whatsoever about
Shandell, the Company or the Released Parties, or any of them, to any person,
entity, the press, subsequent or current employers, in any form on social media,
or to any former or current employees, consultants, customers or suppliers of
the Company except: (a) if the Company is required by law to publicly disclose
this Agreement, such as in an SEC filing, and (b) in a Company press release to
announce that Shandell has stepped down as President, General Counsel, and
member of the Board of Directors, and that Mr. Shandell and the Company have
mutually agreed that now is the right time to transition and to consolidate the
Company’s leadership structure (the “Press Release Announcement”). This includes
oral or written statements including statements that place Shandell, the Company
or any of the Released Parties in a negative light. The Company’s obligations
under this Paragraph C are limited to its (i) current directors and officers,
and only for so long as they are directors and officers of the Company; and (ii)
employees whose responsibilities include human resources, investor relations or
public relations. By way of clarification, and not by way of limitation, the
parties will not, or cause any other person or entity to, publish or post any
negative or disparaging comments about Shandell, the Company or any of the
Released Parties in any social media (e.g., Facebook, Twitter, LinkedIn,
Stocktwits, etc.), or to the press or in any media outlet, or in any other
written or electronic communication whatsoever. If Shandell is asked about his
separation from the Company, he will respond: The Company and I agreed that it
was in the best interest of both parties to separate at this time. If the
Company is asked about Shandell’s separation, the Company will respond: Mr.
Shandell has stepped down as President, General Counsel, and member of the Board
of Directors. Mr. Shandell and the Company have mutually agreed that now is the
right time to transition and to consolidate the Company’s leadership structure.
Further, Shandell agrees and acknowledges that the Company is required by law to
publicly file this Agreement with the SEC in at least the Company's Quarterly
Report on Form 10-Q for the quarter ending June 30, 2020, and to publicly
disclose certain material terms of this Agreement in an 8-K filing.
Additionally, Shandell agrees and acknowledges to the Press Release Announcement
and that the Press Release Announcement is permissible.

2.Nothing in this Paragraph C prohibits either party from disclosing this
Agreement or the facts and circumstances leading up to this Agreement if
compelled to do so by court order or lawful subpoena or in connection with a
dispute between Shandell and the Company concerning the matters contemplated
herein.
3.Nothing in this Agreement (i) waives a party’s right to testify in an
administrative, legislative, or judicial proceeding concerning alleged criminal
conduct or sexual harassment when the party has been required or requested to
attend the proceeding pursuant to a court order, subpoena, or written request
from an administrative agency or the legislature; (ii) prevents Shandell from
making a report or disclosure of information that is protected under the
whistleblower provisions of state or federal law or regulation to any
self-regulatory organization, governmental agency, or legislative body; or (iii)
restricts Shandell from initiating

4

--------------------------------------------------------------------------------

communications directly with, responding to any inquiries from, providing
testimony before, or from filing a claim with or assisting with an investigation
of a self-regulatory authority or a government agency or entity, including the
U.S. Equal Employment Opportunity Commission, the Department of Labor, the
National Labor Relations Board, the Department of Justice, the Securities and
Exchange Commission, the Congress, and any agency Inspector General
(collectively, the “Regulators”).  However, to the maximum extent permitted by
law, Shandell is waiving his right to receive any individual monetary relief
from the Company or any of the Released Parties resulting from such claims or
conduct, regardless of whether Shandell or another party has filed them. This
Agreement also does not limit Shandell’s right to receive an award from any
Regulator that provides awards for providing information relating to a potential
violation of law.  Moreover, Shandell is hereby 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 where
the disclosure is made: (x) in confidence to a federal, state, or local
government official, either directly or indirectly, or to an attorney, and
solely for the purpose of reporting or investigating a suspected violation of
law; (y) in a complaint or other document filed in a lawsuit or other
proceeding, if such filing is made under seal; or (z) to an attorney and used in
a court proceeding in connection with a lawsuit against the employer for
retaliation for reporting a suspected violation of law if the information is
filed under seal and not disclosed except pursuant to court order.  See 18
U.S.C. § 1833(b)(1)-(2).

1.The parties agree that this Agreement is enforceable between the parties
hereto.  If any action or motion is brought to enforce this Agreement, the
prevailing party in such action shall be entitled to reimbursement for
reasonable costs, expenses and attorneys’ fees incurred by it/him in such action
or motion, except where prohibited by law.
