4.4.
Change: In Control Payment. If a Change in Control occurs during the Term (or, with respect to a Change in Control contemplated by Section 1.5(b) or (c) or a Board approved tender offer within one (1) year following the Term if
substantive discussions between the Company and the other party or parties concerning such transaction had commenced during the Term but only if Executives employment with the Company was terminated, prior to such Change in Control, by the
Company without cause or by Executive with good reason), the Company shall pay to Executive a Change in Control payment determined as follows: (a) if the Per Share Value is at least $3.50 but less than $5.00, Executive will receive an amount equal

Executive not later than the effective date of the Change in Control. Executive shall be entitled to only one payment pursuant to this Section 4.4, if applicable, during the Term notwithstanding that more than one Change in Control may occur
during the Term.



4.5. Possible Reduction in
Payments and Benefits. Following any Change in Control, to the extent that any amount of payments or benefits provided to Executive under this Agreement would cause Executive to be subject to excise tax or would fail to be tax deductible to the
Company under Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended (the Code), and after taking into consideration all other amounts payable to Executive under other Company plans, programs, policies and arrangements,
then the amount of payments and benefits provided under this Agreement shall be reduced (first by any payments, and then, to the extent necessary, by any benefits), to the extent necessary to avoid imposition of any such excise taxes and to ensure
that no portion of the payments made to Executive will fail to be tax deductible to the Company by reason of 280G. The determination of whether any payment or benefit would be subject to excise tax will be made in the sole discretion of the Board
based on the advice of the Companys auditors.

(v) influence or attempt to influence any person to either (A) terminate or modify any employment,
consulting, agency, distributorship or other arrangement with the Company, or (B) employ or retain, or arrange to have any other person or entity employ or retain, any person who has been employed or retained by the Company as an employee,
consultant, agent or distributor of the Company at any time during the Restricted Period until the expiration of twelve (12) months from the date such person ceases to have been employed or retained by the Company.



(b) Confidentiality. Executive recognizes and
acknowledges that the Proprietary Information is a valuable, special and unique asset of the business of the Company. As a result, both during the Term and thereafter, Executive shall not, without the prior written consent of the Company, for any
reason either directly or indirectly divulge to any third party or use for his own benefit, or for any purpose other than the exclusive benefit of the Company, any Proprietary Information revealed, obtained or developed in the course of his
employment by the Company; provided, however, that nothing herein contained shall restrict Executives ability to make such disclosures during the Term as may be necessary or appropriate to the effective and efficient discharge of his
duties as an employee hereunder or as such disclosures may be required by law. If Executive or any of his representatives become legally compelled to disclose any of the Proprietary Information, Executive will provide the Company with prompt written
notice so that the Company may seek a protective order or other appropriate remedy.



(c) Property.



(i) All right, title and interest in and to Proprietary Information shall be and remain the sole and exclusive property of the Company. During the Term, Executive shall not remove from the Companys offices or premises
any documents, records, notebooks, files, correspondence, reports, memoranda or similar materials of or containing Proprietary Information, or other materials or property of any kind belonging to the Company unless necessary or appropriate in
accordance with the duties and responsibilities required by or appropriate for his position and, in the event that such materials or property are removed, all of the foregoing shall be returned to their proper files or places of safekeeping as
promptly as possible after the removal shall serve its specific purpose. Executive shall not make, retain, remove and/or distribute any copies of any of the foregoing for any reason whatsoever except as may be necessary in the discharge of his
assigned duties and shall not divulge to any third person the nature of and/or contents of any of the foregoing or of any other oral or written information to which he may have access or with which for any reason he may become familiar, except as
disclosure shall be necessary in the performance of his duties; and upon the termination of his employment with the Company, he shall leave with or return to the Company all originals and copies of the foregoing then in his possession, whether
prepared by Executive or by others.



(ii)
Executive agrees that all the Intellectual Property will be considered works made for hire as that term is defined in Sections 101 and 201 of the Copyright Act (17 U.S.C. §§ 101 and 201) and that all right, title and interest
in such Intellectual



-6-



---



Property will be the sole and
exclusive property of the Company. To the extent that any of the Intellectual Property may not by law be considered a work made for hire, or to the extent that, notwithstanding the foregoing, Executive retains any interest in the Intellectual
Property, Executive hereby irrevocably assigns and transfers to the Company any and all right, title, or interest that Executive may have in the Intellectual Property under patent, copyright, trade secret and trademark law, in perpetuity or for the
longest period otherwise permitted by law, without the necessity of further consideration. The Company will be entitled to obtain and hold in its own name all copyrights, patents, trade secrets, and trademarks with respect to such Intellectual
Property. Executive further agrees to execute any and all documents and provide any further cooperation or assistance reasonably required by the Company to perfect, maintain or otherwise protect its rights in the Intellectual Property. If the
Company is unable after reasonable efforts to secure Executives signature, cooperation or assistance in accordance with the preceding sentence, whether because of Executives incapacity or any other reason whatsoever, Executive hereby
designates and appoints the Company or its designee as Executives agent and attorney-in-fact, to act on his behalf, to execute and file documents and to do all other lawfully permitted acts necessary or desirable to perfect, maintain or
otherwise protect the Companys rights in the Intellectual Property. Executive acknowledges and agrees that such appointment is coupled with an interest and is therefore irrevocable.



5.2. Rights and Remedies Upon Breach.



(a) Specific Enforcement. Executive acknowledges that the Restrictive Covenants are reasonable and
necessary to protect the legitimate interests of the Company and its affiliates and that the Company would not have entered into this Agreement in the absence of such restrictions. Executive also acknowledges that any breach by him, willfully or
otherwise, of the Restrictive Covenants will cause continuing and irreparable injury to the Company for which monetary damages would not be an adequate remedy. Executive shall not, in any action or proceeding to enforce any of the provisions of this
Agreement, assert the claim or defense that such an adequate remedy at law exists. In the event of any such breach by Executive, the Company shall have the right to enforce the Restrictive Covenants by seeking injunctive or other relief in any
court, without any requirement that a bond or other security be posted, and this Agreement shall not in any way limit remedies of law or in equity otherwise available to the Company. If an action at law or in equity is necessary to enforce or
interpret the terms of this agreement, the prevailing party shall be entitled to recover, in addition to any other relief, reasonable attorneys fees, costs and disbursements.



(b) Extension of Restrictive Period. In the event that Executive breaches any of the Restrictive
Covenants contained in Section 5.1(a), then the Restricted Period shall be extended for a period of time equal to the period of time that Executive is in breach of such restriction.



(c) Accounting. If Executive willfully breaches, or threatens to commit a breach of any of the
Restrictive Covenants, the Company will have the right and remedy to require Executive to disclose all compensation, profits, monies, accruals, increments or other benefits derived or received by Executive as the result of any action constituting a
breach of the Restrictive Covenants. This right and remedy will be in addition to, and not in lieu of, any other rights and remedies available to the Company under law or in equity.

5.3.
Judicial Modification. If any court determines that any of the Restrictive Covenants, or any part thereof, is unenforceable because of the duration or scope of such provision, such court shall have the power to modify such provision and, in
its modified form, such provision shall then be enforceable.



5.4. Disclosure of Restrictive Covenants. Executive agrees to disclose the existence and terms of the restrictive covenants set forth in this Section 5 to any employer that Executive may work for during the Restricted
Period and to allow the Company to do the same.



5.5. Acknowledgments. Executive acknowledges that the Restrictive Covenants contained in Section 5.1(a) are included herein in order to induce the Company to employ Executive pursuant to the other terms of this
Agreement and to agree to the provisions of Section 6.2. Executive further acknowledges that the duration and geographic scope of Section 5.1(a) are reasonable given the nature of this Agreement.



5.6. Enforceability. If any court holds the Restrictive
Covenants unenforceable by reason of their breadth or scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect the right of the Company to the relief provided above in the courts of any other
jurisdiction within the geographical scope of such Restrictive Covenants.



SECTION 6. Termination. Subject to the terms of this Agreement, Executives employment hereunder may be terminated at any time. Immediately and automatically upon any termination, Executive agrees that he will be deemed
to have resigned as a member of the Board without any further action required on the part of Executive, the Board or the Company. Furthermore, upon termination, Executive shall be entitled only to such compensation and benefits as described in this

Executives employment with the Company is terminated during the Term for any reason other than as specified in Section 6.2 (including termination by the Company for Cause, as a result of Executives death, as a result of
Executives Disability, or by Executive without Good Reason), then the Companys obligation to Executive will be limited solely to the payment of (a) all accrued but unpaid Base Salary and Benefits through the date of such termination, and
(b) the payment of any accrued but unpaid bonus payable under Section 4.1 with respect to a fiscal year of the Company ending prior to such termination. All Base Salary and Benefits shall cease at the time of such termination, subject to the
terms of any benefits or compensation plans then in force and applicable to Executive, and the Company shall have no further liability or obligation hereunder by reason of such termination.



6.2. Termination Without Cause or With Good Reason. If

of such termination, (b) the payment of any accrued but unpaid bonus payable under Section 4.1 with respect to a fiscal year of the Company ending prior to such termination, (c) a continuation of group health coverage for Executive for the
Severance Period (and, to the extent covered immediately prior to the date of Executives termination, his dependents) with the contributions paid by the Company and the Executive continuing on the same basis as in effect on the date of
Executives termination (as such



-8-

contributions may be changed in accordance with changes for similarly situated employees during the
relevant time period); (d) the payment for the Severance Period of monthly severance payments equal to one-twelfth of his Base Salary as of the date of such termination, and (e) vesting of all of Executives stock options, to the extent not
already vested. The benefits described in this Section 6.2 (c), (d) and (e) shall be paid only if Executive executes a release agreement in a form acceptable to the Company (as set forth in Exhibit C hereto), shall be in lieu of
and not in addition to any other severance arrangement maintained by the Company, and shall be offset by any monies Executive may owe to the Company. Upon the end of the Severance Period, all benefits described in this Section 6.2 (c), (d) and
(e) will cease and the Company shall have no further liability or obligation by reason of such termination. Notwithstanding the foregoing, the Company may elect to waive the application of Section 5.1(a) of this Agreement by written
notice delivered to the Executive within 15 days of his termination and, in that case, Executive will not be entitled to any benefits described in Section 6.2(c), (d) and (e), above. If Executive violates the provisions of Section
5.1(a), the Companys obligations to provide the benefits described in Section 6.2(c), (d) and (e) shall cease and be rendered a nullity.



6.3. Termination Procedures. Any termination of Executives employment by the Company or by Executive during the Term (other

SECTION 7. Expenses. The Company will pay or reimburse Executive for reasonable and necessary expenses directly
incurred in the course of his employment by the Company in accordance with the standard policies and practices of the Company.



SECTION 8. Other Agreements. Executive represents, warrants and, where applicable, covenants to the Company that:



8.1. There are no restrictions, agreements or understandings
whatsoever to which Executive is a party which would prevent or make unlawful Executives execution of this Agreement or Executives employment hereunder, or which are or would be inconsistent or in conflict with this Agreement or
Executives employment hereunder, or would prevent, limit or impair in any way the performance by Executive of his obligations hereunder;



8.2. Executives execution of this Agreement and Executives employment hereunder shall not constitute a breach of any contract,
agreement or understanding, oral or written, to which Executive is a party or by which Executive is bound; and

herein.

performance, enforcement or breach of this Agreement shall be resolved by confidential, final and binding
arbitration (rather than trial by jury or court or resolution in some other forum) to the fullest extent permitted by law. Each party will be responsible for his or its own attorneys fees. Any arbitration proceeding pursuant to this Agreement
shall be conducted in Pennsylvania by the American Arbitration Association (AAA), JAMS or any other mutually agreeable provider, under the then existing employment-related arbitration rules of the applicable provider. If for any reason
all or part of this arbitration provision is held to be invalid, illegal, or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other portion of this
arbitration provision or any other jurisdiction, but this provision will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable part or parts of this provision had never been contained herein,
consistent with the general intent of the parties insofar as possible.



9.2. Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the Company and Executive and their respective successors, executors, administrators, heirs and/or permitted assigns;
provided, however, that neither Executive nor the Company may make any assignments of this Agreement or any interest herein, by operation of law or otherwise, without the prior written consent of the other party, except that, without such
consent, the Company may assign this Agreement to any successor to all or substantially all of its assets and business by means of liquidation, dissolution, merger, consolidation, transfer of assets, or otherwise.
