 This AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT (this “Agreement”) dated March 4, 2003,
between SILICON VALLEY BANK, a California chartered bank (“Bank”), with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054, and with a loan production office located at 9020 Capital of Texas Highway, North,
Building 1, Suite 350, Austin, Texas, 78759 and SIGMATEL, INC., a Texas corporation (“Borrower”), with its principal place of business at the location set forth on the Cover Page of this Agreement, provides the terms on which Bank will
lend to Borrower and Borrower will repay Bank. 
  
 WHEREAS, Bank
and Borrower previously entered into that certain Loan and Security Agreement, dated as of April 9, 2001, pursuant to which Bank agreed to provide a line of credit to Borrower in an amount not to exceed $8,000,000 (referred to herein as the
“Original Loan Documents”); and 
  
 WHEREAS, Borrower
and Bank have agreed to amend and restate the Original Loan Documents. 
  
 NOW, THEREFORE, in consideration of the covenants, conditions and agreements hereinafter set forth, and for other good and valuable consideration, the receipt and adequacy of which are all hereby acknowledged Borrower and Bank agree as
follows: 
  
 1      ACCOUNTING AND OTHER TERMS.

  
 Accounting terms not defined in this Agreement will be
construed following GAAP. Calculations and determinations must be made following GAAP. The term “financial statements” includes the notes and schedules. The terms “including” and “includes” always mean “including
(or includes) without limitation” in this or any Loan Document. 
  
 2      LOAN AND TERMS OF PAYMENT. 
  
 2.1         Promise to Pay.  Borrower will pay Bank the unpaid principal amount of all Credit Extensions and interest on the unpaid principal amount of the Credit Extensions.

  
 2.1.1     Revolving Advances. 
  
 (a) Bank will make Advances not exceeding (i) the lesser of the Committed Revolving Line or the Borrowing Base, minus (ii) the outstanding Obligations under the Other Services Sublimit. Amounts borrowed under this
Section may be repaid and reborrowed during the term of this Agreement. 
  
 (b) To obtain an Advance, Borrower must notify Bank by facsimile or telephone by 3:00 p.m. Pacific time on the Business Day the Advance is to be made. Borrower must promptly confirm the notification by delivering to Bank the Payment/Advance
Form attached as Exhibit B (a “Payment/Advance Form”). Bank will credit Advances to Borrower’s deposit account. Bank may make Advances under this Agreement based on instructions from a Responsible Officer or his or her designee or
without instructions if the Advances are necessary to meet Obligations which have become due. Bank may rely on any telephone notice given by a person whom Bank believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss
Bank suffers due to such reliance. 
  
 (c) The Committed Revolving
Line terminates on the Revolving Maturity Date, when all Advances are immediately payable. 
  
 (d) Bank’s obligation to lend the undisbursed portion of the Obligations will terminate if, in good faith, the Bank determines based on information available to it and in its reasonable judgement, there has been
a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the prospect of repayment of the Obligations, or there has been any material adverse deviation by Borrower from the most recent
business plan of Borrower presented to and accepted by Bank prior to the execution of this Agreement. 
  

 1 

 2.1.2     Other Services Availability. 
  
 (a)    Letters of Credit.  Bank will
issue or has issued letters of credit (each a “Letter of Credit” and collectively, the “Letters of Credit”) for Borrower’s account not exceeding the Other Services Availability. Borrower’s reimbursement obligation will
be secured by cash on terms acceptable to Bank at any time after the Revolving Maturity Date if the term of this Agreement is not extended by Bank. Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank
may reasonably request. 
  
 (b)    Foreign
Exchange Services.  Borrower may enter into foreign exchange forward contracts with the Bank under which Borrower commits to purchase from or sell to Bank a set amount of foreign currency more than one business day after the contract
date (a “FX Forward Contract”). The total FX Forward Contracts at any one time may not exceed 10 times the amount of the Other Services Availability. Bank may terminate the FX Forward Contracts if an Event of Default occurs. 
  
 (c)    Cash Management
Services.  Borrower may use up to the amount of the Other Services Availability for Bank’s Cash Management Services, which may include merchant services, direct deposit of payroll, business credit card, and check cashing services
identified in various cash management services agreements related to such services (the “Cash Management Services”). 
  
 (d)    Effect of Services Usage.  Such aggregate amounts utilized under the Other Services Sublimit will at all times
reduce the amount otherwise available to be borrowed under the Committed Revolving Line. Any amounts Bank pays on behalf of Borrower or any amounts that are not paid by Borrower for any Letters of Credit, FX Forward Contracts or Cash Management
Services will be treated as Advances under the Committed Revolving Line and will accrue interest at the rate for Advances. 
  
 2.1.3     Term Loan. 
  
 (a) Bank will make a Term Loan available to Borrower. 
  
 (b) Borrower will pay 36 equal installments of principal plus Interest as determined by Bank (the “Term Loan Payment”). Each Term Loan Payment
is payable on the first day of each month during the term of the loan, with the first Term Loan Payment due April 1, 2003. Borrower’s final Term Loan Payment, due on March 1, 2006, includes all outstanding Term Loan principal and accrued
interest. 
  
 (c) The Term Loan accrues interest at 1.75
percentage points (1.75%) above the Prime Rate, fixed as of the Effective Date. 
  
 2.2      Overadvances.  If Borrower’s Obligations under Section 2.1.1 and the Other Services Sublimit exceed the lesser of either (i) the Committed Revolving Line or (ii) the Borrowing
Base, Borrower must immediately pay in cash to Bank the excess. 
  
 2.3     Interest Rate; Payments. 
  
 2.3.1     In General. 
  
 (a)    Spreading of Interest.  Due to irregular periodic balances of principal, the variable nature of the interest rate, or prepayment, the total interest that will accrue under this Agreement cannot be
determined in advance. Bank does not intend to contract for, charge or receive more than the Maximum Lawful Rate or Maximum Lawful Amount permitted by applicable state or federal law, and to prevent such an occurrence Bank and Borrower agree that
all amounts of interest, whenever contracted for, charged or received by Bank, with respect to the Obligations, will be spread, prorated or allocated over the full period of time the Obligations are outstanding, including the period of any renewal
or extension thereof. If the maturity of the Obligations is accelerated for any reason whether as a result of an Event of Default or otherwise prior to the full stated term, the total amount of interest contracted for, charged or received to the
time of such demand shall be spread, prorated or allocated along with any interest thereafter accruing over the full period of time that the 

  

 2 

 
Obligations thereafter remain unpaid for the purpose of determining if such interest exceeds the Maximum Lawful Amount. 
  
 (b)    Excess Interest.  At maturity
(whether by acceleration or otherwise) or on earlier final payment of the Obligations, Bank will compute the total amount of interest that has been contracted for, charged or received by Bank or payable by Borrower hereunder and compare such amount
to the Maximum Lawful Amount that could have been contracted for, charged or received by Bank. If such computation reflects that the total amount of interest that has been contracted for, charged or received by Bank or payable by Borrower exceeds
the Maximum Lawful Amount, then Bank shall apply such excess to the reduction of the principal balance, and any remaining excess shall be refunded to Borrower. This provision concerning the crediting or refund of excess interest shall control and
take precedence over all other agreements between Borrower and Bank so that under no circumstances shall the total interest contracted for, charged or received by Bank exceed the Maximum Lawful Amount. 
  
 (c)    Request to Debit Accounts.  Bank
may debit any of Borrower’s deposit accounts including Account Number 3300067179 for principal and interest payments or any amounts Borrower owes Bank. Bank will notify Borrower when it debits Borrower’s accounts. These debits are not a
set-off. Payments received after 12:00 noon Pacific time are considered received at the opening of business on the next Business Day. 
  
 2.3.2      Committed Revolving Line. 
  
 (a)    Interest Rate.  Advances under the Committed Revolving Line accrue interest on the outstanding principal
balance thereof at a per annum rate 1.00 percentage point (1%) above the Prime Rate. The interest rate on the Committed Revolving Line increases or decreases when the Prime Rate changes. Interest is computed on a 360 day year for the actual number
of days elapsed. Bank will not compute the interest in a manner that would cause Bank to contract for, charge or receive interest that would exceed the Maximum Lawful Rate or the Maximum Lawful Amount. After an Event of Default, Obligations accrue
interest at the Default Interest Rate. The Default Interest Rate is the least of (i) the Maximum Lawful Rate, if the Maximum Lawful Rate is established by applicable law, or (ii) the interest rate applicable immediately prior to the occurrence of
the Event of Default plus 5 percentage points, if no Maximum Lawful Rate law has been established by applicable law; or (iii) 18% per annum; or (iv) such lesser rate of interest as Bank in its sole discretion may choose to charge; but in no event
more than the Maximum Lawful Rate. 
  
 (b)    Payments.  Interest on the Committed Revolving Line is payable on the first day of each month. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day
and additional fees or interest accrue. 
  
 2.4
     Fees.  Borrower will pay to Bank: 
  
 (a)    Facility Fees.  A fully earned, non-refundable facility fee on the Committed Revolving Line in the amount of $15,000 due on the date that Borrower executes and delivers this
Agreement to Bank and $10,000 due on the first anniversary of the Effective Date, and a fully earned, non-refundable facility fee on the Term Loan in the amount of $5,000, due on the date that Borrower executes and delivers this Agreement to Bank;
and 
  
 (b)    Bank
Expenses.  All Bank Expenses (including reasonable attorney’s fees and expenses) incurred through and after the Effective Date when due; and 
  

(c)    Letter of Credit Fee.  A Letter of Credit Fee in the amount of 1.25% per year of the face amount of each
Letter of Credit, which is due on the date of issuance of such Letter of Credit and on each anniversary date thereof during the existence of such Letter of Credit; and 
  
 (d)    Usage Fee.  A usage fee, payable in arrears within 15 days of the end of each
calendar quarter, in an amount equal to the product of .375% times the average Unused Balance for such fiscal 

  

 3 

 
quarter. The term “Unused Balance” shall mean the result of (i) the lessor of the Committed Revolving Line or the Borrowing Base minus (ii) the
aggregate amount of all Advances. 
  
 2.5
     Additional Costs.  If any law or regulation increases Bank’s costs or reduces its income for any loan, Borrower will pay the increase in cost or reduction in income or additional expense.

  
 3      CONDITIONS OF LOANS. 

 
 3.1      Conditions Precedent to Initial Credit
Extension.  Bank’s obligation to make the initial Credit Extension is subject to the condition precedent that it receive the following: 
  

(a) the agreements, documents and fees it requires; and 
  
 (b) evidence satisfactory to Bank in Bank’s sole discretion of a minimum investment of new equity in an amount not less than $6,870,000. 

 
 3.2      Conditions Precedent to all Credit
Extensions.  Bank’s obligations to make each Credit Extension, including the initial Credit Extension, is subject to the following: 
  
 (a) timely receipt of any Payment/Advance Form, as applicable; and 
  
 (b) the representations and warranties in Section 5 must be materially true on the date of the Payment/Advance Form, as
applicable and on the effective date of each Credit Extension and no Event of Default may have occurred and be continuing, or result from the Credit Extension. Each Credit Extension is Borrower’s representation and warranty on that date that
the representations and warranties in Section 5 remain true. 
  
 4      CREATION OF SECURITY INTEREST. 
  
 4.1      Grant of Security Interest.  Borrower grants Bank a continuing security interest in all presently existing and later acquired Collateral to secure all Obligations and performance of
each of Borrower’s duties under the Loan Documents. Except for Permitted Liens, any security interest will be a first priority security interest in the Collateral. Bank may place a “hold” on any deposit account pledged as Collateral;
provided that Bank agrees that it will not place a “hold” on any such deposit account, unless and until there is an Event of Default and any such “hold” shall not be for an amount greater than the total aggregate amount of the
Obligations. If this Agreement is terminated, Bank’s lien and security interest in the Collateral will continue until Borrower fully satisfies its Obligations. 
  
 4.2      Authorization to File.  Borrower authorizes Bank to file financing statements
without notice to Borrower, with all appropriate jurisdictions, as Bank deems appropriate, in order to perfect or protect Bank’s interest in the Collateral. 
  
 5      REPRESENTATIONS AND WARRANTIES. Borrower represents and warrants as follows:

  
 5.1      Due Organization and
Authorization.  Except as otherwise set forth on the Schedule, Borrower and each Subsidiary is duly existing and in good standing in its state of formation and qualified and licensed to do business in, and in good standing in, any
state in which the conduct of its business or its ownership of property requires that it be qualified. 
  
 The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with Borrower’s formation documents, nor
constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which or by which it is bound in which the default could cause a Material Adverse Change. 
  

 4 

 5.2      Collateral.  Borrower has good title to the Collateral, free of
Liens except Permitted Liens or Borrower has rights to each asset that is Collateral. Borrower has no other deposit account, other than the deposit accounts described in the Schedule. The Accounts are bona fide, existing obligations, and the service
or property has been performed or delivered to the account debtor or its agent for immediate shipment to and unconditional acceptance by the account debtor. The Collateral is not in the possession of any third party bailee (such as at a warehouse),
except as set forth on the Schedule. In the event that Borrower, after the date hereof, intends to store or otherwise deliver the Collateral to such a bailee, then Borrower will receive the prior written consent of Bank and such bailee must
acknowledge in writing that the bailee is holding such Collateral for the benefit of Bank; provided, that, Borrower shall not be required to acquire such consent of Bank and acknowledgement from bailee for Collateral stored or otherwise delivered to
a bailee in a foreign country. Borrower has no notice of any actual or imminent Insolvency Proceeding of any account debtor whose accounts are an Eligible Account in any Borrowing Base Certificate. All Inventory is in all material respects of good
and marketable quality, free from material defects. 
  
 5.3
     Litigation.  Except as shown in the Schedule, there are no actions or proceedings pending or, to the knowledge of Borrower’s Responsible Officers, threatened by or against Borrower or any
Subsidiary in which a likely adverse decision could reasonably be expected to cause a Material Adverse Change. 
  
 5.4      No Material Adverse Change in Financial Statements.  All consolidated financial statements for Borrower, and any Subsidiary, delivered to Bank fairly present
in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations. There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the
most recent financial statements submitted to Bank. 
  
 5.5
     Solvency.  The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; the Borrower is not left with unreasonably small
capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature. 
  
 5.6      Regulatory Compliance.  Borrower is not an “investment company” or a company “controlled” by
an “investment company” under the Investment Company Act. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulation U of the Federal Reserve Board of Governors). Borrower has complied
with the Federal Fair Labor Standards Act. To Borrower’s knowledge, Borrower has not violated any laws, ordinances or rules, the violation of which could cause a Material Adverse Change. None of Borrower’s or any Subsidiary’s
properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Borrower and
each Subsidiary has timely filed all required tax returns and paid, or made adequate provision to pay, all material taxes. Borrower and each Subsidiary has obtained all consents, approvals and authorizations of, made all declarations or filings
with, and given all notices to, all government authorities that are necessary to continue its business as currently conducted. 
  
 5.7      Subsidiaries.  Borrower does not own any stock, partnership interest or other equity securities except for
Permitted Investments, as set forth on the Schedule. 
  
 5.8
     Full Disclosure.  No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank contains any untrue statement of a material fact or omits
to state a material fact necessary to make the statements contained in the certificates or statements not misleading. 
  
 6      AFFIRMATIVE COVENANTS.  Borrower will do all of the following for so long as Bank has an obligation to lend, or
there are outstanding obligations: 
  
 6.1
     Government Compliance.  Borrower will maintain its and all Subsidiaries’ legal existence and good standing in its jurisdiction of formation and maintain qualification in each jurisdiction in
which the failure to so qualify could reasonably be expected to have a material adverse effect on Borrower’s business or operations. Borrower will comply, and have each Subsidiary comply, with all laws, ordinances and regulations to which it

  

 5 

 
is subject, noncompliance with which could have a material adverse effect on Borrower’s business or operations or could reasonably be expected to cause
a Material Adverse Change. 
  
 6.2      Financial
Statements, Reports, Certificates. 
  
 (a) Borrower will
deliver to Bank: (i) as soon as available, but no later than 30 days after the last day of each month, a company prepared consolidated balance sheet and income statement covering Borrower’s consolidated operations during the period, in a form

threatened against Borrower or any Subsidiary that could result in damages or costs to Borrower or any Subsidiary of $100,000 or more; (v) prompt notice of any material change in the composition of the Intellectual Property, including any subsequent

operating plans or other financial information Bank requests. 
  
 (b) Within 30 days after the last day of each month, Borrower will deliver to Bank a Borrowing Base Certificate signed by a Responsible Officer in the form of Exhibit C, with aged listings of accounts receivable and accounts payable.

  
 (c) Within 30 days after the last day of each month, Borrower
will deliver to Bank with the monthly financial statements a Compliance Certificate signed by a Responsible Officer in the form of Exhibit D. 
  
 (d) Allow Bank to audit Borrower’s Collateral within 6 months after the Effective Date. Subsequent audits of Borrower’s Collateral shall occur
not less than annually, but no more than semi-annually unless an Event of Default has occurred and is occurring. All audits of Borrower’s Collateral shall be conducted at Borrower’s expense. 
  
 (e) No later than December 1 of each year, Borrower shall deliver to Bank in
the same form and content as those previously provided to Bank Borrower’s financial projections and forecasts for the subsequent year. 
  
 6.3      Inventory; Returns.  Borrower will keep all Inventory in good and marketable condition, free from material
defects. Returns and allowances between Borrower and its account debtors will follow Borrower’s customary practices as they exist at the Effective Date. Borrower must promptly notify Bank of all returns, recoveries, disputes and claims that
involve more than $200,000. 
  
 6.4
     Taxes.  Borrower will make, and cause each Subsidiary to make, timely payment of all material federal, state, and local taxes or assessments and will deliver to Bank, on demand, appropriate

days after it occurs, or if the default cannot be cured within 10 days or cannot be cured after Borrower’s attempts in the 10 day period, and the default may be cured within a reasonable time, then Borrower has an additional period, (of not

 8.3      Material Adverse Change. 
  
 (i) A material impairment in the perfection or priority of the Bank’s

 8.5      Insolvency.  (i) if Borrower
becomes insolvent; (ii) if Borrower begins an Insolvency Proceeding; or (iii) an Insolvency Proceeding is begun against Borrower and not dismissed or stayed within 60 days (but no Credit Extensions will be made before any Insolvency Proceeding is

 9      BANK’S RIGHTS AND
REMEDIES. 
  
 9.1      Rights and
Remedies.  When an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following: 
  
 (a) Declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations are immediately due
and payable without any action by Bank); 
  
 (b) Stop advancing
money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Bank; 
  
 (c) Settle or adjust disputes and claims directly with account debtors for amounts, on terms and in any order that Bank considers advisable; 

 
 (d) Make any payments and do any acts it considers necessary or reasonable
to protect its security interest in the Collateral. Borrower will assemble the Collateral if Bank requests and make it 

  

 9 

 
available as Bank designates. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay,
purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of
Bank’s rights or remedies; 
  
 (e) Apply to the Obligations
any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower; 
  
 (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Bank is granted a
non-exclusive, royalty-free license or other right to use, without charge, Borrower’s labels, Patents, Copyrights, Mask Works, rights of use of any name, trade secrets, trade names, Trademarks, service marks, and advertising matter, or any
similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses
and all franchise agreements inure to Bank’s benefit; and 
  
 (g) Dispose of the Collateral according to the Code. 
  
 9.2
     Power of Attorney.  Effective only when an Event of Default occurs and continues, Borrower irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower’s name on any checks or
other forms of payment or security; (ii) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against account debtors, (iii) make, settle, and adjust all claims under Borrower’s insurance policies; (iv) settle
and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits. Bank may exercise the
power of attorney to sign Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred. Bank’s appointment as Borrower’s attorney in
fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates. 
  
 9.3      Accounts Collection.  When an Event
of Default occurs and continues, Bank may notify any Person owing Borrower money of Bank’s security interest in the funds and verify the amount of the Account. Borrower must collect all payments in trust for Bank and, if requested by Bank,
immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit. 
  
 9.4      Bank Expenses.  If Borrower fails to pay any amount or furnish any required proof of payment to third persons
Bank may make all or part of the payment or obtain insurance policies required in Section 6.5, and take any action under the policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due and payable, bearing interest at
the then applicable rate and secured by the Collateral. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default. 
  
 9.5      Bank’s Liability for Collateral.  If Bank complies with reasonable banking
practices, it is not liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or
other person. Borrower bears all risk of loss, damage or destruction of the Collateral. 
  
 9.6      Remedies Cumulative.  Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements are cumulative. Bank has all rights and remedies provided
under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay is not a waiver, election, or acquiescence. No waiver
is effective unless signed by Bank and then is only effective for the specific instance and purpose for which it was given. 
  

 10 

 9.7      Demand Waiver.  Borrower waives demand, notice of default or
dishonor, notice of acceleration, notice of intent to accelerate, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel
paper, and guaranties held by Bank on which Borrower is liable.

 1Executive Employment Agreement

 Exhibit 10.11 
 EXECUTIVE EMPLOYMENT AGREEMENT 
  
 THIS EXECUTIVE EMPLOYMENT AGREEMENT (this “Agreement”), dated as of March 26, 2001, is entered into by and between SigmaTel, Inc., a Texas corporation (the “Company” or the “Employer”), and Ronald Edgerton (the
“Employee”) (either party individually, a “Party”; collectively, the “Parties”). 
  
 WHEREAS, the Company desires to retain the services of Employee as President and Chief Executive Officer of the Company; and 
  
 WHEREAS, the Parties desire to enter into this Agreement to set forth the
terms and conditions of Employee’s employment by Employer, to address certain matters related to Employee’s employment with Employer, and to restrict certain activities by Employee that the Parties acknowledge and agree would constitute
unreasonable and unfair competition and detract from Employee’s loyalty and commitment to Employer; 
  
 NOW, THEREFORE, in consideration of the foregoing and the mutual provisions contained herein, and for other good and valuable consideration, the Parties
hereto agree as follows: 
  
 1.    Duties
and Responsibilities.    Employer wishes to employ and Employee hereby accepts the position of President and Chief Executive Officer. Employee shall perform the duties, services and functions relating to such employment or
otherwise reasonably incident to such employment, and such responsibilities, duties, services and functions as may be determined by the Board of Directors of the Company (the “Board”). Employee may be reassigned or transferred to another
management position, as designated by the Board in accordance with the terms and conditions of this Agreement. Employee agrees to abide by all by-laws, policies, practices, procedures, or rules of the Company. Notwithstanding the foregoing sentence,
but subject to the provisions of Section 7 and 8 below, nothing in this Section 1 will prevent the Employee from engaging in activities that do not materially interfere with the Employee’s duties and responsibilities for the Company at that
time or with his personal investments or community affairs. 
  
 2.    Term.    The term of this Agreement shall commence on March 26, 2001 (the “Effective Date”). Employee’s employment with the Company pursuant to this Agreement is for no
specified term, and may be terminated by the Company at any time, with or without cause, and with or without notice. Similarly, Employee may terminate Employee’ s employment with the Company at any time, with or without cause and with or
without notice. During Employee’s employment by the Company, Employee will devote Employee’s full time best efforts to the interests of the Company and will not engage in other employment or in any activities determined by the Company to
be detrimental to the best interests of the Company without the prior written consent of the Company. The Company acknowledges that the Employee has certain continuing consulting obligations to clients of his company, Edgerton Consulting, and the
Company consents to Employee’s completing those consulting obligations under the following conditions: (i) the consulting work shall not be performed for any competitor of the Company; (ii) the consulting 

  

 1 

 
obligations shall not cause Employee to devote less than 40 hours per week to his duties under this Agreement; and (iii) Employee shall complete the
consulting obligations on or before May 31, 2001. The period from the Effective Date to the termination of Employee’s employment with the Company is defined as the “Employment Term.” 
  
 3.    Location.    During the
Employment Term, Employee shall serve the Company with his principal place of employment at the Company’s offices in Austin, Texas. The Company may request that Employee undertake reasonable business travel related to the responsibilities of
his position. 
  
 4.    Compensation and
Employee Benefits.    Upon the terms and subject to the conditions herein, the Company will compensate Employee for his employment during the Employment Term as follows: 
  
 A.    Salary.    The Company will pay Employee a monthly Base Salary of $20,833.33 per month, subject to applicable withholding, in accordance with the Company’s normal payroll procedures
(the “Salary”), subject to periodic (but not less often than annual) review and adjustment by the Board, from time to time. 
  
 B.    Performance Bonuses.    Employee shall have the opportunity to earn a Performance
Bonus based upon the achievement of objectives (the “Objectives”) determined by the Compensation Committee of the Board. The level of Employee’s Performance Bonus opportunity will be determined annually by the Board, with the
level for each calendar year during which this Agreement is in effect being targeted at 50% of Employee’s Salary for that year, as shall be determined by the Board from time to time. The Bonus may be adjusted as determined from time to time by
the Compensation Committee of the Board. In every case, the Bonus shall be subject to such withholdings or other deductions as may be required by applicable law. 
  
 C.    Incentive, Savings and Retirement Plans.    The Company
will permit the Employee to participate in other incentive, savings and retirement plans, as adopted from time to time by the Board, that are tax-qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended (the “Code”),
and all plans that are supplemental to any such tax-qualified plans, in each case to the extent that such plans are applicable generally to other senior executives of the Company and are approved by the Board. 
  
 D.    Benefits.    Employee shall have the right, on the same basis as other senior executives of the Company, to participate in and to receive benefits under any of the Company’s employee
benefit plans, in effect from time to time. 
  
 E.    Expenses.    Subject to the requirements of the business expense reimbursement policies and procedures of the Company as in effect from time to time that are approved by the Board, the
Employee is authorized to incur, and the Company will reimburse the Employee for reasonable out-of-pocket expenses in the course of performing his duties under 
  

 2 

 this Agreement including, without limitation, reasonable business meals, entertainment, travel, and
cellular phone expenses. Without limitation of the preceding sentence, the Company will reimburse the Employee for reasonable expenses for weekly round-trip air travel between Asheville, North Carolina and Austin, Texas. 
  
 F.    Vacation and
Holidays.    The Company will provide to the Employee paid vacation in accordance with the plans, policies, programs and practices of the Company, that are approved by the Board, providing not less than five (5) weeks (25
business days) vacation per year, and all legal holidays during which times Employee’s applicable compensation shall be paid in full. Paid vacation days which are unused in any calendar year shall not accrue to the next calendar year, nor shall
any additional compensation be paid to Employee for any vacation days unused in any calendar year. 
  
 G.    Fringe Benefits.    The Company will furnish to Employee those fringe benefits, if
any, offered generally to other senior executives of the Company including, by way of example only, office space, computers and associated software, and reserved parking spaces that are approved by the Board. 
  
 H.    Relocation
Payment.    The parties acknowledge that it is the present intention of Employee to maintain his primary residence in Asheville, North Carolina and to commute weekly to Austin, Texas. In order to defray the costs of
Employee’ s establishing a secondary residence in Austin, Texas, the Company shall pay to Employee, on or before June 30, 2001, a relocation payment of $35,000, subject to such withholdings or other deductions as may be required by applicable
law. 
  
 5.    Discoveries and
Inventions. 
  
 A.    Employee hereby assigns and agrees to assign to the Employer all his right, title and interest in and to any and all work products (individually, a “Work Product”; collectively, the “Work
Products”), whether tangible or intangible and whether patentable or not, which Employee conceives, reduces to practice, reduces to writing or other storage media or otherwise creates either alone or jointly with others in the course of his
employment and which pertain to any business activity of Employer. 
  
 B.    If any of such Work Product is created wholly or in part by Employee during his hours of actual work for Employer, or with the aid of Employer’s materials, equipment or personnel, or
arises out of or relates to any business activity of Employer, then such creation shall be deemed conclusively to have occurred in the course of his employment, and shall be the sole property of Employer. It is recognized that Employee will perform
the duties assigned to him at times other than his actual work hours and Employer’s rights hereunder shall not be diminished because the Work Product was created at such other times. 
  
 C.    Employee agrees to perform all acts necessary to enable Employer to learn of and
protect the rights it receives hereunder, including, but not limited to, making full and 
  

 3 

 
immediate disclosure to Employer of any of the above and assisting, upon request of Employer, in the preparation and execution of all documents required to
acquire and convey to Employer patent and copyright protection in the United States and elsewhere or to otherwise protect Employer’s interest therein. 
  
 D.    Employee agrees that the terms of this Section 5 apply with respect to Work Products created in the course of
Employee’s employment by the Employer prior to the effective date of this Agreement for Employer or its predecessor entities. “Inventions” (inventions, trade secrets, ideas, processes, formulas, data, programs, other original works of
authorship, improvements, discoveries, developments, designs and techniques), if any, patented or unpatented, which Employee made prior to the commencement of employment with Employer are excluded from the scope of this Agreement. To preclude any
possible uncertainty, set forth on Exhibit A attached hereto is a complete list of all Inventions that Employee has, alone or jointly with others, conceived, developed or reduced to practice or caused to be conceived, developed or reduced to
practice prior to commencement of Employee’s employment with Employer, that Employee considers to be his property or the property of third parties and that Employee wishes to have excluded from the scope of this Agreement. If disclosure of any
such Invention on Exhibit A would cause Employee to violate any prior confidentiality agreement, Employee understands that he is not to list such Inventions in Exhibit A but is to inform the Company that all Inventions have not been listed for that
reason. 
  
 E.    Employee
agrees to cooperate fully and in all respects to protect and preserve Employer’s interest in any Work Product, subject to the terms of this Section 5, and shall provide any declarations and testimony incident thereto, both during and subsequent
to Employee’s term of employment with Employer. 
  
 6.    Confidential Information. 
  
 A.    As consideration for employment and to aid and assist Employee in carrying out his duties, Employer agrees to provide to Employee non-public and Confidential Information (as hereinafter
defined) about Employer, which in the reasonable judgment of Employer would assist Employee in the performance of his duties. For the purposes of this Agreement, the term “Confidential Information” shall mean information of any nature, in
any form, and from any source which at the time or times concerned is not generally known or available to the public or to persons engaged in business similar to that conducted or contemplated by the Employer, and includes, without limitation,
customer lists or information relating to clients or customers, trade secrets, processes, inventions, discoveries, developments, modifications, improvements, ideas, know-how, techniques, designs, data, programs, processes, formulae, code and all
other work products, marketing or pricing strategies, marketing efforts, internal cost and profit information, information related to Employer personnel and other confidential and non-public information relating to the Employer, its employees,
affiliates, clients, and customers. Employee agrees that he will not, either during the Employment Term or at any time thereafter, divulge or appropriate for 
  

 4 

 
his own use or the use of others or disclose to any unauthorized person, firm or corporation any Confidential Information, and Employee confirms that such
information constitutes the exclusive property of Employer. Employee shall return all tangible evidence of such Confidential Information to Employer prior to or at the termination of his employment. 
  
 B.    In the event that Employee breaches
or threatens to breach the provisions of this Section 6, Employee agrees that Employer shall be entitled to obtain a restraining order and/or injunction restraining and enjoining Employee from disclosing all or any part of such Confidential
Information and to restrain and enjoin Employee from rendering any service to any firm, corporation, association, or any other entity to whom all or any part of such Confidential Information has been, or is threatened to be, disclosed. In addition
to the above, Employer may pursue any and all other legal or equitable remedies available to Employer for such breach or threatened breach, including, but not limited to, the recovery of damages from Employee. 
  
 7.    Obligation of Loyalty to the Employer.

  
 A.    During the
Employment Term and following the termination of this Agreement, Employee agrees that he will not: 
  

	 	(i)	 	Make any statement or perform any act intended to advance an interest of any existing or prospective competitor of Employer or solicit or encourage any other employee of Employer to
do any act that is disloyal to Employer or inconsistent with the Employer’s interests or in violation of any provision of this Agreement; 

  

	 	(ii)	 	Inform any existing or potential client, customer, supplier or creditor of Employer that Employee intends to resign, or make any statement or do any act intended to cause any
existing or potential client, customer, supplier or creditor of Employer to learn of Employee’s intention to resign; or 

  

	 	(iii)	 	Discuss with any existing or potential client, customer, supplier or creditor of Employer the present or future availability of services or products provided by a business which
competes with Employer. 

  
 B.    The parties hereto each agree that Section 7A imposes reasonable restraints on the Employee in light of the activities and business of Employer on the date hereof and the current business plans of Employer. The
Employee acknowledges and agrees that the consideration given by Employer under this Agreement gives rise to Employer’s interest in restraining and prohibiting the Employee from engaging in the prohibited activities described in Section 7A. It
is the desire and intent of each of the parties that the provisions of Section 7A shall be enforced to the fullest extent permissible under the laws and public policies applied in the State of Texas. Accordingly, if any particular portion of Section
7A shall be 
  

 5 

	 	 
adjudicated to be invalid or unenforceable, Section 7A shall be deemed amended (i) to reform the particular portion to provide for such maximum restrictions
as will be valid and enforceable or, if that is not possible, then (ii) to delete therefrom only the portion thus adjudicated to be invalid or unenforceable. Section 7A shall inure to the benefit of any successor to the Employer.

  
 8.    Non-Competitive
Agreement and Restrictive Covenant. 
  
 A.    During the Employment Term and for a period of time after the date of termination of Employee’s employment with the Company equal to the number of months calculated pursuant to Section 11B(ii) below (such
period of time, for purposes of this Section 8 only, to be a minimum of six (6) months and a maximum of twelve (12) months), Employee hereby agrees to refrain from: 
  

	 	(i)	 	either directly or indirectly carrying on or engaging in a business which directly competes with that of Employer at the time this Agreement terminates; and

  

	 	(ii)	 	either directly or indirectly owning, managing, operating, controlling, being employed by, working for, participating in or being connected in any manner with the ownership,
management, operation or control of a business that directly competes with (i) that of Employer at the time this Agreement terminates or (ii) a line of business that Employer has taken active steps to enter (where Employee is aware of those steps)
at the time this Agreement terminates (provided, however, that nothing herein prevents or restrains Employee from owning or controlling less than 5% of the outstanding shares of voting stock of any publicly traded company that directly competes with
the business of Employer at the time this Agreement terminates, so long as Employee has no active participation in the business of such company), 

  

in either case anywhere in the United States of America; and 
  

	 	(iii)	 	either directly or indirectly soliciting clients, customers and/or employees of Employer, including soliciting any employee of Employer to participate in or assist with the
formation or operations of any business that directly competes with that of Employer (or that is intended to compete with any such business) at the time this Agreement terminates or with respect to the possible future employment of such other
employee by any such business. 

  
 B.    The parties hereto each agree that Section 8A imposes a reasonable restraint on the Employee in light of the activities and business of Employer, and that such restraint is 
  

 6 

	 	 
intended only to protect the goodwill and other legitimate business interests of Employer. Employee agrees that this non-competition agreement is enforceable
and is ancillary to or part of this Agreement. The Employee acknowledges and agrees that the consideration given by Employer under this Agreement, including the disclosure to Employee of Employer’s Confidential Information as provided under
Section 6 and the agreement to pay Severance Benefits in appropriate circumstances pursuant to Section 11B, gives rise to Employer’s interest in restraining and prohibiting the Employee from engaging in the prohibited activities described in
Section 8A. Employee further agrees that the limitations imposed upon Employee in this non-competition agreement as to time, geographic area and scope of activity prohibited are reasonable and do not impose a greater restraint than is
necessary to protect the goodwill and other legitimate business interests of Employer. It is the desire and intent of each of the parties that the provisions of Section 8A shall be enforced to the fullest extent permissible under the laws and public
policies applied in the State of Texas. Accordingly, if any particular portion of Section 8A shall be adjudicated to be invalid or unenforceable, Section 8A shall be deemed amended (i) to reform the particular portion to provide for such maximum
restrictions as will be valid and enforceable or, if that is not possible, then (ii) to delete therefrom only the portion thus adjudicated to be invalid or unenforceable. Section 8A shall inure to the benefit of any successor to the Employer.

  
 C.    In
the event of Employee’s actual or threatened breach of any of the provisions of this Section, Employer shall be entitled to a temporary restraining order and/or injunction restraining Employee from violating such provisions. 
  
 9.    Remedy.    Employee and
the Company acknowledge that the Company will be irreparably harmed by the material breach or the threatened breach of this Agreement by the Employee under Sections 5, 6, 7, and 8 above and consent and agree that, in the event of any such material
breach or threatened breach, the Company may, in addition to the other remedies which may be available to it, file a suit to enjoin the Employee from the such material breach or threatened breach. 
  
 10.    Consolidation, Merger, or Sale of
Assets.    If the Company disposes of its properties and business or of one or more of its divisions or affiliates, substantially as an entirety, by merger, consolidation, sale of assets, or otherwise, then the Company may
assign this Agreement and all of its rights and obligations hereunder to the acquiring or surviving person or entity; provided that such surviving person or transferee entity shall assume in writing all of the obligations of the Company hereunder;
and provided further that whether or not such person or entity so assumes those obligations, the Employee’s rights hereunder will continue as provided by contract or law. 
  
 11.    Termination of Employment. 
  
 A.    For Due Cause. 
  

	 	(i)	 	If the Company has Due Cause (as hereinafter defined) to terminate the Employment Term, the Company will be entitled to terminate the 

  

 7 

	 	 
Employment Term at any time by delivering written notice of that termination to the Employee, in which event (a) that termination will be effective
immediately on the delivery of that notice, (b) the Company will only be obligated to pay to the Employee his Salary accrued and unpaid to the date of that termination; and (c) all the rights and benefits the Employee may have under Section 11B(iii)
& (iv) below; 

  

	 	(ii)    “Due	 	Cause” means: 

  

	 	(a)	 	the Employee has committed a willful serious act, such as fraud, embezzlement or theft, against the Company, intending to enrich himself at the expense of the Company;

  

	 	(b)	 	the Employee has been convicted of (i) a misdemeanor involving the Employee’s intentionally engaging in conduct that is demonstrably materially injurious to the Company or (ii)
a felony, and has, in either case, exhausted all opportunities for appeal of such conviction; 

  

	 	(c)	 	the Employee, in carrying out his duties hereunder, has been guilty of gross neglect or willful misconduct; 

  

	 	(d)	 	the Employee has materially breached this Agreement by repeatedly failing to follow the policies established by the Board of Directors of the Corporation in the performance of
Employee’s duties hereunder and has failed to remedy that breach within fifteen (15) days after receipt of written notice from the Corporation that the breach has occurred. 

  
 B.    General Power.    The
Company may terminate the Employment Term at any time without Due Cause by providing written notice of that termination to the Employee, in which event: 
  

	 	(i)	 	the Company will pay to Employee his Salary accrued and unpaid to the date his employment terminates; 

  

	 	(ii)	 	the Company will pay to Employee his Salary at the rate in effect on the date of his employment termination, less applicable withholding, for the number of months following his
termination equal to the sum of (a) six (6) months plus (b) three (3) additional months for each full year of employment with the Company completed by Employee; 

  

 8 

	 	(iii)	 	the Company will pay premiums for Employee’s COBRA coverage, for the number of months following his termination equal to the sum of (a) six (6) months plus (b) three (3)
additional months for each full year of employment with the Company completed by Employee – thereafter, unless otherwise limited by (1) the Company’ s employee benefit plans and programs, (2) federal law, and/or (3) Texas law allowing for
a 6-month extension of COBRA benefits in certain circumstances upon the Company’s receipt of Employee’s petition for such an extension, Employee will have the right to pay premiums for COBRA coverage equal to the cost of such coverage to
the Company, which right will continue (unless otherwise limited as provided above) until Employee secures similar coverage through future employment or otherwise, plus; and 

  

	 	(iv)	 	all the rights and benefits Employee may have under the employee benefit, vacation, and/or incentive plans and programs, if any, of the Company, will be administered in accordance
with the terms and conditions of those plans and programs. 

  
 Those benefits under subsection (i) – (iii) of this Section 11B together are referred to as the “Severance Benefits.” If Employee dies following termination under this Section 11B, but before the full
payment of all Severance Benefits due under this Agreement, the remaining Severance Benefits will be paid to the estate of Employee. 
  
 C.    Employee Termination Rights. 
  

	 	(i)	 	General Power.    The Employee may voluntarily terminate the Employment Term at any time by providing at least thirty (30) days prior written notice to
the Company, in which event the Company will pay to the Employee his Salary and all other benefits and compensation accrued and unpaid to the date his Employment Term terminates. 

  

	 	(ii)	 	Contractual Grounds.    Nothing in this Agreement prevents Employee from terminating the Employment Term at any time by delivery of written notice of that
termination to the Company. However, if Employee terminates the Employment Term, Employee will only be entitled to Severance Benefits under this Section 11.C if Employee has Contractual Grounds (as defined hereinafter) to terminate the Employment
Term. If the Employee has Contractual Grounds (as defined hereinafter) to terminate the Employment Term, the Employee will be entitled to terminate the Employment Term at any time by delivering a thirty (30) day prior written notice of that
termination to the Company;

	 	(iii)	 	“Contractual Grounds” means: 

  

	 	(a)	 	the Company reassigns Employee to a position either (1) involving a material reduction in the nature, character or responsibility of his position or (2) with a materially lower
Salary than his prior position; or 

  

	 	(b)	 	the Company assigns Employee to a position that requires Employee to relocate his residence away from the Asheville, North Carolina or Austin, Texas area. 

 
 Upon Employee’s termination under this Section 11C for Contractual Grounds, Company
shall pay Employee those Severance Benefits described in Section 11B. If Employee dies following termination under this Section 11C for Contractual Grounds, but before full payment of all Severance Benefits under this Agreement, the remaining
Severance Benefits will be paid to the estate of Employee. 
  
 D.    Due to Death.    If the Employee dies, this Agreement shall terminate on the date of death, in which event: 
  

	 	(i)	 	the estate of the Employee shall be entitled to the Employee’s Salary through the end of the period of six (6) months from the date on which he died and no longer; and

  

	 	(ii)	 	all other rights and benefits the Employee (or his estate) may have under the employee benefit, vacation, bonus and/or incentive plans and programs of the Company that shall have
been approved or adopted by the Board, if any, shall be determined in accordance with the terms and conditions of those plans and programs but which, in any event, will continue in effect for benefit of the immediate family of Employee for a period
of six (6) months from date of death (unless a longer period is mandated by any state or federal law). 

  
 E.    Disability.    “ Disability” shall mean the inability or incapacity (by reason of a
medically determinable physical or mental impairment) of the Employee to perform the duties and responsibilities related to his job or position with the Company for a period of at least ninety (90) days, or Employee otherwise becoming legally
incapacitated. If the Employee suffers a Disability, the Company may terminate this Agreement. If the Employee suffers a Disability and the Company elects to terminate Employee, the Employee shall be entitled (i) to all rights and benefits that the
Employee may have under the employee benefit plans and programs of the Company, in accordance with the terms and conditions of such plans and programs; or (ii) if the Company has no employee benefit plan or program in place to provide disability
benefits to Employee, Severance Benefits as defined in Section 11B.

time enter into stock option agreements and/or other forms of equity compensation agreements, and this Section 17 in no way limits the effectiveness of such agreements.

unenforceable by reason of any existing or subsequently enacted legislation or by the final judgment of any court of competent jurisdiction, the Employee and the Company shall promptly meet and negotiate substitute provisions for those rendered or
declared illegal or unenforceable to preserve the original intent of this Agreement to the extent legally possible, but all other provisions of this Agreement shall remain in full force and effect. 
  
 21.    Non-assignment by
Employee.    The obligations of the Employee under this Agreement are personal to him, and no such obligations shall be subject to voluntary or involuntary alienation, assignment or transfer, except as otherwise contemplated

express written waiver which has been signed by the waiving party. The waiver by either party to this Agreement of a breach of any provision of the Agreement by the other party shall not operate or be construed as a waiver by such party of any
subsequent breach by such other party.
