EXHIBIT 10.28 EMPLOYMENT AGREEMENT

2.    Compensation; Benefits; Expenses.

(a)     During Executive’s employment, the Company shall pay Executive an annual base salary (“Base Salary”) and such bonuses and other compensation as set by the Company from time to time, less applicable withholdings, payable in equal installments pursuant to the Company’s regular payroll dates and procedures. Executive shall also be eligible to participate in the incentive compensation plans associated with Executive’s position as offered by the Company from time to time. With respect to any date, the sum of (i) Executive’s then-current annual base salary and (ii) the average annual cash incentive bonus paid or payable to Executive in respect of the two most recent fiscal years ending prior to such date is referred to in this Agreement as Executive’s “Cash Compensation” as of such date. For the avoidance of doubt, if the annual cash incentive bonus for any fiscal year has not yet been paid on the date

when determining Cash Compensation, the accrued and unpaid amount of such bonus for such fiscal year shall be used for purposes of such determination.

(b)     Subject to the terms of any applicable benefit plan or policy, Executive shall be eligible to receive such fringe benefits as are, and may be, made available to other executive employees of the Company from time to time in the exclusive discretion of the Company. The Company reserves the right to modify or discontinue any benefit already provided or as may be provided in the future, with or without notice, as applicable on a Company-wide basis or to all comparable Company executives.

(c)     The Company shall reimburse Executive for all reasonable and deductible out‑of‑pocket expenses which are incurred and submitted by Executive in a timely manner in connection with the performance by Executive of duties hereunder during the term of this Agreement, provided that Executive as may be required obtains prior written approval from the Company to incur such expenses and submits proper documentation in accordance with the Company’s policies and procedures in effect from time to time.

3.    Termination.

(a)     By Death. Executive’s employment hereunder shall terminate automatically upon the date of Executive’s death. The Company shall pay to Executive’s beneficiaries or estate, as appropriate, the Base Salary earned through the date of death without further obligation to Executive, except as set forth in Section 3(g).

(b)    By Disability. Executive’s employment hereunder shall terminate as consistent with applicable law on the last day of the month in which Executive becomes disabled. The Company shall pay to Executive the Base Salary earned through the date of termination without further obligation to Executive, except as set forth in Section 3(g). For this purpose, a disability is the inability of Executive to perform on a full-time basis the duties and responsibilities of his employment with the Company by reason of his illness or other physical or mental impairment or condition, if such inability continues for a period in excess of 180 days during any period of 365 days.

(c)    By Company for Cause. The Company may terminate Executive’s employment hereunder for Cause (as defined below) at any time by giving written notice to Executive. The Company shall pay to Executive the Base Salary to which he is entitled through the end of the day of such termination without further obligation to Executive.

(d)    By Company Without Cause. The Company may terminate Executive’s employment hereunder at any time without Cause. Executive agrees that the Company may dismiss him under this Section 3(d) without regard to (i) any general or specific policies (whether written or oral) of the Company relating to the employment or termination of its employees, or (b) any statements made to Executive, whether made orally or in writing, that pertain to Executive’s relationship with the Company. In the event of such termination, the Company shall pay to Executive the Base Salary to which he is entitled through the date of such termination without further obligation to Executive, except as expressly set forth in Section 4.

(e)    By Resignation. Executive may terminate employment with the Company at any time upon 30 calendar days prior written notice to the Company. The Company reserves the right to waive this notice period or any portion thereof and accelerate Executive’s separation date accordingly; provided that the Company shall pay to Executive his Base Salary though the full notice period.

(f)    By Mutual Consent. Executive and the Company may terminate this Agreement by written mutual consent pursuant to the terms as agreed upon between the parties.

(g)    Benefits or Incentive Compensation upon Termination. Upon Executive’s termination of employment for any reason, Executive’s rights and interests under the Company’s benefit or incentive compensation plans applicable to him shall be determined under the provisions of those respective plans.

(h)    Officer and Director Status. Upon Executive’s termination of employment for any reason, Executive shall be deemed to have resigned from any and all officer and director positions, if any, Executive may then hold with the Company and its affiliates, in each case effective upon such termination of employment.

(i)    Surrender of Records and Property. Upon termination of his employment with the Company for any reason, or at the Company’s earlier request, Executive shall deliver promptly to the Company originals and all copies of all records, manuals, books, blank forms, documents, letters, memoranda, notebooks, reports, data, tables, or calculations, including notes relating to the same, whether in tangible or electronic format or media, that are the property of the Company or its affiliates or that relate in any way to the business, products, practices or techniques of the Company or its affiliates and all other property, trade secrets and confidential information of the Company or its affiliates, including, but not limited to, all office keys, security cards, credit cards, office equipment, computer hardware and software, company products and prototypes, and all documents or electronic records which in whole or in part contain any trade secrets or confidential information of the Company or its affiliates, that in any of these cases are in his possession or under his control. Executive may not retain any copies of the documents referred to in this Section 3(i), other than agreements and other instruments under which Executive has binding legal obligations. To the extent that Executive has downloaded or stored any proprietary, privileged, confidential or trade secret information belonging to the Company or its affiliates on any personal, non-Company electronic media in Executive’s possession, custody, or control, such as computers, cell phones, hand-held devices, back-up devices, zip drives, and the like, Executive agrees to promptly contact the Company to arrange for transfer of such documents and information back to the Company and for destruction of such documents and information on Executive’s personal electronic media.

(j)    Survival. Notwithstanding any termination of this Agreement or Executive’s employment hereunder, Executive shall remain bound by the provisions of this Agreement which specifically relate to periods, activities or obligations upon or subsequent to the termination of Executive’s employment, including without limitation the provisions of Sections 3(i) and 5.

4.    Severance Payments and Benefits

(a)    In Connection With Change in Control. Subject to the conditions set forth below, if a Change in Control occurs and Executive’s employment is terminated involuntarily by the Company in a termination not For Cause, or if Executive terminates his employment with the Company for Good Reason, in either case within 30 days prior, on the date of, or within two years following, such Change in Control, Executive will be entitled to the following:

(i)    Severance pay in an amount equal to two times Executive’s Cash Compensation as of effective date of termination.

(iii)    Payment equal to a prorated portion of Executive’s expected annual cash incentive bonus for the fiscal year in which the effective date of termination occurs based on actual Company and/or individual performance through the effective date of termination, prorated based on the number of calendar days in such fiscal year in which Executive was employed by the Company (the “Prorated Bonus”). The amount of the Prorated Bonus shall be determined by the Company in its sole discretion, taking into account any monthly bonus accruals for purposes of the Company’s financial accounting in the fiscal year in which the effective date of termination occurs, the Company’s historical bonus practices and the then-current business conditions.

(iv)    Notwithstanding anything to the contrary herein, this Section 4(a) shall be of no force or effect and Executive shall have no rights to any payments or benefits hereunder following the second anniversary of the first Change in Control following the date hereof (or, if Executive becomes entitled to severance payments or benefits under this Section 4(a) prior to such second anniversary, the last day of the Severance Period) (the “Severance Termination Date”).

(b)    Other than in Connection With Change in Control. Subject to the conditions set forth below, if a Change in Control occurs and Executive’s employment is terminated involuntarily by the Company in a termination not For Cause, or if Executive

terminates his employment with the Company for Good Reason, in either case on or after two years following such Change in Control, Executive will be entitled to severance pay in an amount equal to 12 months of Executive’s Base Salary.

(c)    The severance pay described in Section 4(a)(i) or 4(b), as applicable (“Severance Pay”) and Prorated Bonus, if applicable, will be paid in substantially equal installments during the period commencing on the later of (i) the effective date of termination and (ii) the date of the Change in Control (the “Severance Commencement Date”), and ending on the second anniversary of the Severance Commencement Date (in the case of payments under Section 4(a)) or the first anniversary of the Severance Commencement Date (in the case of payments under Section 4(b)) (the “Severance Period”), in accordance with the Company’s regular payroll practices, provided that (1) Executive signs and does not revoke a waiver and release agreement in the form acceptable to the Company on or prior to the 60th day following the Severance Commencement Date; and (2) any revocation period of such waiver and release agreement has expired as of such 60th day; provided, further, that no portion of the Severance Pay or Prorated Bonus shall be made on or prior to the 60th day following the Severance Commencement Date (and any amount that would have otherwise been paid prior to such 60th day shall be paid on the first payroll date on or following such 60th day), subject to execution and non-revocation of the waiver and release agreement in accordance with this Section 3.

(d)    As clarification, (i) no severance pay or benefits shall be due or paid if Executive’s termination of employment is For Cause, or as a result of Executive’s death, disability, voluntary resignation (not for Good Reason) or retirement, and (ii) to the extent Executive is entitled to any severance pay or benefits under this Agreement upon termination of employment, such severance pay and/or benefits shall represent the sole severance pay or benefits to which Executive is entitled and Executive hereby waives any other right to severance pay or benefits upon such termination.

5.    Covenants.

(a)    Restrictive Covenants. Executive acknowledges and agrees that, in consideration for the Company’s obligations set forth herein and other good and valuable consideration, the sufficiency of which is hereby acknowledged and agreed, from the date of this Agreement during employment and through the last day of the Severance Period, Executive shall be subject to, and comply with, the restrictive covenants set forth on Exhibit A; provided, however, that in the event that during such period Executive is terminated or resigns and is not entitled to severance or benefits hereunder, then notwithstanding the foregoing, Executive shall be subject to the terms of Exhibit A through the second anniversary of the date of such termination or resignation.

(b)    Non-disclosure Covenant. Except as directed by the Company or as may be required in the proper discharge of Executive’s employment hereunder, Executive shall not, during the term of his employment by the Company or at any time thereafter regardless of the reason for termination, directly or indirectly, divulge, furnish or make accessible to anyone or use in any way any confidential, trade secret, privileged, or proprietary information of the Company or its customers, including without limitation, whether or not reduced to writing and

whether in computerized, electronic, or other form, any customer lists, customer files or information, account information, planning and financial information, contracts, sales and marketing information, insurance information, business strategy or opportunities for new or developing business, that Executive has prepared, acquired or become acquainted with during his employment by the Company, whether developed by Executive or others. Executive acknowledges that the above-described knowledge or information is the property of the Company that constitutes a unique and valuable asset and represents a substantial investment by the Company, and that any disclosure or other use of such knowledge or information, other than for the sole benefit of the Company, would be wrongful and would cause irreparable harm to the Company. Executive agrees to at all times maintain the confidentiality of such knowledge or information, to refrain from any acts or omissions that would reduce its value to the Company, and to take and comply with reasonable security measures to prevent any accidental or intentional disclosure or misappropriation. Executive specifically understands and agrees that he has no right to, and shall not without the Company’s express written permission, download any of the Company’s confidential, trade secret, privileged, or proprietary information onto any electronic storage device or send any such information by email to any email address owned by Executive or by any person other than the Company. The foregoing obligations of confidentiality shall not apply to any knowledge or information the entirety of which is now or subsequently becomes generally and publicly known, other than as a direct or indirect result of the breach of this Agreement by Executive or a breach of a confidentiality obligation owed to the Company by any third party. In the event Executive is requested or required (by oral questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or other process) to disclose any proprietary, privileged, confidential or trade secret information belonging to or relating to the Company, Executive agrees to provide the Company with prompt notice of any such request or requirement so that the Company may seek an appropriate protective order or waive his compliance with the provisions of this Agreement.

(c)    Assignment of Intellectual Property. Executive will promptly disclose in writing to the Company complete information concerning each and every invention, discovery, improvement, device, design, apparatus, practice, process, method or product, whether patentable or copyrightable or not, made, developed, perfected, devised, conceived or first reduced to practice by Executive, either solely or in collaboration with others, during the period of Executive's employment hereunder, whether or not during regular working hours, relating either directly or indirectly to the business, products, practices or techniques of the Company or its affiliates (hereinafter referred to as "Developments"). Executive will keep reasonably complete accounts, notes, data and records of all Developments in the manner and form requested by the Company. Executive, to the extent that he has the legal right to do so, hereby acknowledges that any and all of such Developments are the property of the Company and hereby assigns and agrees to assign to the Company any and all of Executive’s right, title and interest in and to any and all of such Developments. Upon request and whether during the period of Executive's employment hereunder or thereafter, Executive will do all lawful acts, including, but not limited to, the execution of papers and lawful oaths and the giving of testimony, that in the opinion of the Company may be necessary or desirable in obtaining, sustaining, reissuing, extending and enforcing United States and foreign letters patent, including, but not limited to, design patents, or other applicable registrations, on any and all of such Developments, and for

perfecting, affirming and recording the Company’s complete ownership and title thereto, and to cooperate otherwise in all proceedings and matters relating thereto. The provisions of this Section 5(c) shall not apply to any Development meeting the following conditions: (a) such Development was developed entirely on Executive's own time; and (b) such Development was made without the use of any Company equipment, supplies, facility or trade secret information; and either (c) such Development does not result from any work performed by Executive for the Company, or (d) such Development does not relate (i) directly to the business of the Company or (ii) to the Company’s actual or demonstrably anticipated research or development.

6.    Section 280G.

(a)    Except as otherwise provided in Section 6(b) below, in the event that it shall be determined that any right to receive any payment or other benefit under this Agreement to or for the benefit of Executive, would, in whole or part, when aggregated with any other right, payment or benefit to or for Executive under all other agreements or benefit plans of the Company and its affiliates (the payments and benefits under this Agreement and such other rights, payments and benefits, collectively, the “Payments”), be nondeductible by the Company (or other person making such payment or providing such benefit) as a result of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and/or would subject Executive to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”) then, to the extent necessary to make the Payments deductible and to exempt the Payments from the Excise Tax (but only to such extent and after taking into account any reduction in the Payments relating to Section 280G of the Code under any other plan, arrangement or agreement), the Payments shall be reduced (if necessary, to zero). The Payments shall be reduced by the Company in its reasonable discretion in the following order: (i) first, the Severance Pay and Prorated Bonus, (ii) second, any other cash payments or benefits otherwise payable to Executive that are exempt from Section 409A (as defined below), but excluding any payment attributable to the acceleration of vesting or payment with respect to any stock option or other equity award with respect to the Company's securities that are exempt from Section 409A, (iii) third, any other payments or benefits otherwise payable to Executive on a pro-rata basis or such other manner that complies with Section 409A, but excluding any payment attributable to the acceleration of vesting and payment with respect to any stock option or other equity award with respect to the Company's securities that are exempt from Section 409A, and (iv) fourth, any payments attributable to the acceleration of vesting or payment with respect to any stock option or other equity award with respect to the Company's securities that are exempt from Section 409A.

(b)    Notwithstanding any other provision of this Agreement, the provisions of Section 6(a) above shall not apply to reduce the Payments if the Payments that would otherwise be nondeductible under Section 280G of the Code and/or would subject Executive to the Excise Tax are disclosed to and approved by the Company’s stockholders in accordance with Section 280G(b)(5)(B) of the Code and the Department of Treasury regulations thereunder.

(c)    The Company shall use commercially reasonable efforts to prepare and deliver to its stockholders the disclosure required by Section 280G(b)(5)(B) of the Code with

respect to the Payments and seek the approval of the Company’s stockholders pursuant to subsection (b) above.

(i) any material adverse change by the Company in such Executive’s job title, duties, responsibility or authority (provided that a modification in the person or entity to whom Executive reports as a result of the transition of the Company (or its underlying business) into a subsidiary or division of a larger entity in connection, or the change of Executive’s job title (along with commensurate duties, responsibility and authority) to President, in either case in connection with a Change in Control shall not constitute a material adverse change under this subsection (i));

Except as required by law, no right to receive payments under this Agreement shall be subject to anticipation, commutation, alienation, sale, assignment, encumbrance, charge, pledge or hypothecation or to execution, attachment, levy or similar process or assignment by operation of law, and any attempt, voluntary or involuntary, to effect any such action shall be null, void and of no effect.

10.    Injunctive Relief. Each party acknowledges that any breach of this Agreement by it or him would cause irreparable injury to the other party for which money damages alone would not constitute an adequate remedy. Accordingly, each party agrees that the other party shall be entitled to seek injunctive relief to enforce the obligations under this Agreement. The party seeking injunctive relief shall not be required to post any bond or other security in order to obtain such injunctive relief.

11.    Arbitration. Any and all claims, disputes, controversies, or disagreements of any kind whatsoever arising out of or relating to this Agreement shall be settled by arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules; provided that the Company may bring claims against Executive to seek injunctive relief under this Agreement in a court of competent jurisdiction. Such arbitration shall be conducted in Denver, Colorado.

Notwithstanding any laws, rules or regulations that may provide for class action litigation, the arbitrator will have no authority to consider a class action by one or more executives or employees; nor will the arbitrator have authority to otherwise preside over any form of a representative or class proceeding. The decision of the arbitrator shall be final, conclusive and binding on the parties to the arbitration. The award of the arbitrator may be enforced in any court of competent jurisdiction. BY SIGNING THIS AGREEMENT, EXECUTIVE AND COMPANY ARE EACH GIVING UP HIS/HER/ITS RIGHT TO A JURY TRIAL AND, EXCEPT AS PROHIBITED BY LAW, HIS/HER/ITS RIGHT TO PARTICIPATE IN A CLASS ACTION BECAUSE, EXCEPT AS OTHERWISE SET FORTH IN THIS SECTION 11, ALL CLAIMS WILL BE RESOLVED EXCLUSIVELY THROUGH ARBITRATION. EXECUTIVE AND COMPANY AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN HIS/HER/ITS INDIVIDUAL CAPACITY AND

NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING.

12.    Attorney Fees. If any arbitration, proceeding or action at law or in equity, including any action for declaratory or injunctive relief, is brought which arises out of this Agreement, or which seeks to enforce or interpret this Agreement or to seek damages for its breach, the prevailing party shall be entitled to recover reasonable attorney fees from the non-prevailing party, which fees may be set by the court or arbitration in the trial of such action, or may be enforced in a separate action brought for that purpose, and which fees shall be in addition to any other relief which may be awarded. For purposes of this Section 12, Executive will not be deemed to be a “prevailing party” unless he obtains a final award that is in an amount equal or greater to the Cash Compensation and that is not subject to appeal (and that, but for any action for relief by Executive, would not have equaled or exceeded such amount).

13.    Severability and Reformation. The parties hereto intend all provisions of this Agreement to be enforced to the fullest extent permitted by law, and are intended to be limited to the extent necessary so that they will not render this Agreement illegal, invalid, or unenforceable under present or future law. If any provision of this Agreement or any application thereof shall be held to be invalid, illegal or unenforceable, then, subject to Section 9 of Exhibit A, the validity, legality and enforceability of such provision shall be fully severable, and this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision were never a part hereof and the remaining provisions shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance.

14.    Notices. All notices and other communications required or permitted to be given hereunder shall be in writing and shall be deemed to have been duly given if delivered personally, mailed by certified mail (return receipt requested) or sent by recognized overnight delivery service to the parties at the following addresses or at such other addresses as shall be specified by the parties by like notice:

15.    409A Provisions.

(b)    Notwithstanding any other provision of this Agreement to the contrary, to the extent that any payment under this Agreement constitutes “nonqualified deferred compensation” under Section 409A, the following shall apply to the extent Section 409A is applicable to such payment:

(i)    Any payable that is triggered upon Executive’s termination of employment shall be paid only if such termination of employment constitutes a “separation from service” under Section 409A;

(ii)    For purposes of Section 409A, Executive’s right to receive installment payments of any severance amount, if applicable, shall be treated as a right to receive a series of separate and distinct payments;

(iii)    To the extent that any reimbursement of expenses or in-kind benefits constitutes “deferred compensation” under Section 409A, such reimbursement or benefit shall be provided no later than December 31 of the year following the year in which the expense was incurred. The amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year. The amount of any in-kind benefits provided in one year shall not affect the amount of in-kind benefits provided in any other year; and

(iv)    In the event that Executive is deemed on the date of termination to be a “specified employee” as defined in Section 409A, then with regard to any payment or the provision of any benefit that is subject to Section 409A and is payable on account of a separation from service (as defined in Section 409A), such payment or benefit shall be delayed for until the earlier of (a) the first business day of the seventh calendar month following such termination of employment, or (b) Executive’s death. Any payments delayed by reason of the prior sentence shall be paid in a single lump sum, without interest thereon, on the date indicated by the previous sentence and any remaining payments due under this Agreement shall be paid as otherwise provided herein.

16.    Governing Law and Venue. This Agreement is to be governed by and construed in accordance with the laws of the State of Colorado without regard to the conflicts of law principles of any jurisdiction.

This Agreement may not be altered or amended, nor may any of its provisions be waived, except by a writing signed by both parties hereto or, in the case of an asserted waiver, by the party against whom the waiver is sought to be enforced.

18.    No waiver. No term or condition of this Agreement shall be deemed to have been waived, except by a statement in writing signed by the party against whom enforcement of the waiver is sought. Any written waiver shall not be deemed a continuing waiver unless specifically stated, shall operate only as to the specific term or condition waived, and shall not constitute a waiver of such term or condition for the future or as to any act other than that specifically waived.

19.    Counterparts. This Agreement may be executed in counterparts, with the same effect as if both parties had signed the same document. All such counterparts shall be deemed an original, shall be construed together and shall constitute one and the same instrument.
