 ESCROW AGREEMENT 
 THIS ESCROW AGREEMENT (this “Agreement”) is made and entered into
as of February 4, 2006 by and among Sirenza Microdevices, Inc., a Delaware corporation (“Parent”), Phillip Chuanze Liao (“Seller”), individually and as Company Shareholders Agent, and Yeechin Shiong Liao
(“Spouse” and, together with Seller, the “Company Shareholders”) and U.S. Bank National Association, as escrow agent hereunder (the “Escrow Agent”). 
 RECITALS 
 A. The Company
Shareholders are the sole shareholders of Premier Devices, Inc., a California corporation (the “Company”). 
 B. Parent,
Penguin Acquisition Corporation, a California corporation and a wholly owned subsidiary of Parent (“Merger Sub”), the Company and the Company Shareholders are parties to that certain Merger Agreement, dated as of February 4,
2006 (the “Merger Agreement”), pursuant to which Parent shall acquire the Company through the statutory merger of the Company with and into Merger Sub (the “Merger”). All capitalized terms that are used but not
defined herein shall have the respective meanings ascribed thereto in Merger Agreement. 
 C. Pursuant to the terms of the Merger Agreement,
Parent and the Company Shareholders have agreed to deposit (or cause to be deposited) three million five hundred thousand (3,500,000) shares of Parent Common Stock that are included in the Aggregate Merger Consideration (the “Escrowed
Stock”) or cash into an escrow fund to be governed by the terms and conditions set forth in this Agreement. 
 NOW, THEREFORE, in
consideration of the foregoing premises, and the mutual covenants, agreements, representations and warranties set forth herein, and for other good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged and
accepted, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 
 1. Creation of Escrow Fund.

 (a) Pursuant to Section 2.8(a) of the Merger Agreement, at the Effective Time, Parent shall withhold the Escrowed
Stock from the Aggregate Merger Consideration otherwise payable or issuable pursuant to the Merger Agreement to the Company Shareholders. As soon as practicable following the Closing Date (but in no event later than five (5) business days
following the Closing Date), Parent shall cause the Escrowed Stock to be deposited with the Escrow Agent to be held in an escrow fund (the “Escrow Fund”) to be governed by the terms and conditions set forth in this Agreement. Each
Company Shareholder shall be deemed to have contributed to the Escrow Fund such holder’s Pro Rata Portion of Escrowed Stock to be held by the Escrow Agent pursuant to the Merger Agreement and this Agreement. 

 (b) The Escrow Agent shall accept delivery of the Escrowed Stock. At any time during the
term of the Escrow Fund, Seller may elect on behalf of the Company Shareholders to (i) deposit with the Escrow Agent an aggregate amount of cash equal to (x) $7,125,000 less (y) the aggregate amount of Losses for which the
Parent Indemnified Parties (or any of them) have been theretofore indemnified pursuant to Article X of the Merger Agreement by (A) payment in cash or (B) release of Escrowed Stock from the Escrow Fund (the “Escrow Cash
Amount”) or (ii) subject to Parent’s policies and practices with respect to insider trading and confidential information, cause the orderly sale of any remaining Escrowed Stock from the Escrow Fund (on behalf of the Company
Shareholders) by written instruction from Seller to the Escrow Agent. In the event that Seller shall elect to cause the sale of Escrowed Stock from the Escrow Fund pursuant hereto, all of the proceeds from such sales shall be deposited into the
Escrow Fund until the aggregate net cash proceeds raised through such sales and deposited into the Escrow Fund shall be equal to the Escrow Cash Amount, whereupon the Escrow Agent shall promptly release to each of the Company Shareholders the
balance of the Escrowed Stock and any proceeds thereon then held in the Escrow Fund in excess of the Escrow Cash Amount, based on the Pro Rata Portion of Escrowed Stock deemed to have been contributed to the Escrow Fund by each such Company
Shareholder pursuant to the Merger Agreement. The Escrow Agent shall hold the Escrowed Stock, Escrow Cash Amount or proceeds thereon in the Escrow Fund and disburse the Escrow Fund upon the terms and subject to the conditions of this Agreement.

 (c) During the term of this Agreement, the Escrow Fund shall be available as security for the indemnification obligations
of the Company Shareholders payable to the Parent Indemnified Parties under Article X of the Merger Agreement, and shall be disbursed in accordance with the terms and conditions set forth in this Agreement. 
 2. Claims Against Escrow Fund. 
 (a) A Parent Indemnified Party shall be entitled to make claims against the Escrow Fund in connection with any indemnification claim to recover Losses in accordance with Article X of the Merger Agreement at any
time after the date hereof and prior to 11:59 p.m. (Mountain Standard time) on the second anniversary of the Closing Date (the “Expiration Date”). A Parent Indemnified Party may make such a claim against the Escrow Fund by
delivering an Indemnification Claim Notice to the Seller in accordance with Section 10.5 of the Merger Agreement and a copy thereof to the Escrow Agent. 
 (b) The Escrow Agent shall not disburse any portion of the Escrow Fund in respect of any claim against the Escrow Fund unless and until
the validity of such claim is finally resolved, either (i) by mutual agreement of the applicable Parent Indemnified Party and the Seller, (ii) by a court of competent jurisdiction, and the Escrow Agent receives written notice of such
resolution from the applicable Parent Indemnified Party or the Seller (a “Resolved Claim Notice”) or (iii) upon written request by the Parent Indemnified Party to the Escrow Agent, if Seller shall fail to object in writing to
an Indemnification Claim Notice pursuant to Section 11.5(c) of the Merger Agreement to 

  

 -2- 

 
any individual item of Loss set forth in an Indemnification Claim Notice within thirty (30) calendar days after Seller’s receipt of such
Indemnification Claim Notice. Within five (5) calendar days after receipt of a Resolved Claim Notice (or after the date that is thirty (30) calendar days following receipt of an Indemnification Claim Notice in the case of a failure to
object in writing within thirty (30) days) that provides for the disbursement of all or part of the Escrow Fund to a Parent Indemnified Party, the Escrow Agent shall disburse to such Parent Indemnified Party an amount of the Escrow Fund equal
to the recovery amount set forth in such Resolved Claim Notice or Indemnification Claim Notice in the case of a failure to object in a timely manner (a “Parent Escrow Payment”). 
 (c) In the event that any Escrowed Stock is used to satisfy indemnification claims set forth in a Resolved Claim Notice or Indemnification
Claim Notice in the case of a failure to object in writing within thirty (30) days, such Escrowed Stock will be valued for such purpose at the closing price per share of Parent Common Stock as reported on the NASDAQ National Market (or such
other principal exchange or automated quotation system on which Parent Common Stock is then trading) on the date of final resolution of the claim or the date of the tolling of the period in which Seller must timely object to an Indemnification Claim
Notice, as the case may be. 
 (d) Notwithstanding anything else to the contrary set forth herein, the Escrow Agent shall
disburse the Escrow Fund at any time and from time to time upon, and in accordance with, any joint written instructions that the Escrow Agent may receive from Parent and the Seller. 
 3. Release of Escrow Fund on Expiration Date. 
 (a) Within two (2) Business Days after the Expiration Date, the Escrow Agent shall disburse to the Company Shareholders in proportion to their respective Pro Rata Portions of Escrowed Stock (x) any amount of
the Escrow Fund then remaining in the possession of the Escrow Agent, plus (y) all income earned prior to the Expiration Date on such Escrow Fund and remaining therein as of such date, if any, less (z) an amount of Escrow
Fund (the “Retained Escrow Fund”) that is equal to the aggregate amount of then pending and unresolved claims against the Escrow Fund theretofore made by any Parent Indemnified Parties pursuant to Section 2 hereof (the
“Aggregate Outstanding Claims). In the event that Escrowed Stock is to make up part or all of the Retained Escrow Fund, such shares shall be valued for such purpose at the closing price per share of Parent Common Stock as reported on the
NASDAQ National Market (or such other principal exchange or automated quotation system on which Parent Common Stock is then trading) on the Expiration Date. 
 (b) In the event and to the extent that, following the Expiration Date, any claim against the Escrow Fund theretofore made by any Parent
Indemnified Party or Parties pursuant to Section 2 hereof is resolved against such Parent Indemnified Party or Parties, promptly thereafter the Escrow Agent shall disburse to the Company Shareholders such amounts of the Retained Escrow
Fund corresponding to the amount of the claim against the Escrow Fund that was resolved against such Parent Indemnified 

  

 -3- 

 
Party or Parties in proportion to their respective Pro Rata Portions of Escrowed Stock, unless the amount of any and all then remaining Aggregate Outstanding
Claims (after giving effect to such resolved claim) would otherwise exceed the Retained Escrow Fund after giving effect to such disbursement, in which case such amounts shall not be disbursed to the Company Shareholders to the extent necessary so
that the Retained Escrow Fund would equal the amount of any and all remaining Aggregate Outstanding Claims (after giving effect to such resolved claim). 
 (c) The disbursement of any portion of the Escrow Fund to the Company Shareholders shall be treated for tax purposes as additional merger consideration paid to the Company Shareholders, on the date of the release from
the Escrow Fund, on behalf of Parent pursuant to the Merger Agreement; provided, however, that the parties shall treat as interest paid to the Company Shareholders in connection with any such disbursements the amount required to be
treated as interest to the Company Shareholders pursuant to the imputed interest rules of the Internal Revenue Code of 1986, as amended (the “Code”). 
 4. Duties of Escrow Agent; Protection of the Escrow Fund. 
 (a) The Escrow Agent shall
perform such duties and obligations as are set forth herein in accordance with the terms and provisions of this Agreement. 
 (b) The Escrow Agent shall (i) safeguard and treat the Escrow Fund as a trust fund in accordance with the provisions of this Agreement, and shall hold the Escrow Fund in a separate account or accounts, apart from any other funds or
accounts of the Escrow Agent or any other Person and (ii) hold and dispose of the Escrow Fund only in accordance with the terms and provisions of this Agreement. 
 (c) Following the Closing, the duties of the Escrow Agent with respect to the Escrow Fund may be altered, amended, modified or revoked
only by a writing signed by Parent, Seller and the Escrow Agent. 
 (d) Any shares of Parent Common Stock or other equity
securities issued or distributed by Parent (including shares issued upon a stock split) (“New Shares”) in respect of Parent Common Stock in the Escrow Fund which have not been released from the Escrow Fund shall be added to the
Escrow Fund and become a part thereof. New Shares issued in respect of shares of Parent Common Stock which have been released from the Escrow Fund shall not be added to the Escrow Fund but shall be distributed to the recordholders thereof. Cash
dividends on Parent Common Stock shall not be added to the Escrow Fund but shall be distributed to the recordholders thereof. 
 (e) Each Company Shareholder shall have voting rights with respect to the shares of Parent Common Stock contributed to the Escrow Fund on behalf of such Company Shareholder (and on any voting securities added to the Escrow Fund in respect
of such shares of Parent Common Stock). 
  

 -4- 

 5. Permitted Investments of Escrow Fund by the Escrow Agent. 
 (a) The Escrow Agent shall hold the Escrow Fund in escrow and shall invest any cash in the Escrow Fund, including without limitation any
proceeds, interest, and dividends received on the Escrow Cash Amount or Escrowed Stock, as the case may be, only in Permitted Investments. For purposes of this Agreement, “Permitted Investments” shall mean investments consisting
exclusively of one or more of the following, as may be selected from time to time by written instruction from Parent and the Seller: (i) direct obligations of the United States government having maturities of ninety (90) days or less;
(ii) money market deposit accounts with U.S. Bank National Association, whose short-term debt ratings are not less than A-1/P-1; and (iii) money market funds that invest solely in direct obligations of the United States government. In the
absence of written instructions to the contrary, the Escrow Agent shall invest the Escrow Fund in the Escrow Agent’s Insured Money Market Account. 
 (b) The Escrow Agent shall not be liable for any loss incurred by the actions of third parties or by any loss arising by error, failure or delay in the making of an investment or reinvestment, and the Escrow Agent
shall not be liable for any loss of principal or income in connection therewith, unless such error, failure or delay results from the Escrow Agent’s gross negligence, willful misconduct or breach of this Agreement. 
 (c) As and when any portion of the Escrow Fund is to be released pursuant to Section 2 hereof or Section 3 hereof,
the Escrow Agent shall cause the Permitted Investments to be converted into cash in accordance with its customary procedures and shall not be liable for any loss of principal or income in connection therewith. The Escrow Agent shall not be liable
for any loss of principal or income due to the choice of Permitted Investments in which the Escrow Cash Amount is invested or the choice of Permitted Investments converted into cash pursuant to this Section 5. 
 (d) All income earned on the Escrow Fund, if any, shall become part of, and be held as an additional portion of, the Escrow Fund. The
parties hereto agree that the Company Shareholders shall be treated as the owner of the Escrow Fund for Tax purposes unless and until disbursed in accordance with this Agreement, and that all interest on or other taxable income, if any, earned from
the investment of the Escrow Fund shall be treated for Tax purposes as income of the Company Shareholders. Upon any release of the Escrow Fund to the Company Shareholders, a portion of such amount distributed may be treated as interest under the
imputed interest rules of the Code. Within ten (10) calendar days after the end of each calendar quarter, forty percent (40%) of the income earned on the portion of the Escrow Fund treated as owned by the Company Shareholders during such
quarter shall be distributed to the Company Shareholders in proportion to their respective Pro Rata Portion of Escrowed Stock. The Escrow Agent shall file with the Internal Revenue Service and issue to the Company Shareholders appropriate Treasury
Forms 1099 reflecting the earnings from the investment of the Escrow Fund for each calendar year. Notwithstanding the foregoing, no portion of the Escrow Fund shall be released except as expressly provided for in this Agreement.

 6. Exculpatory Provisions. 
 (a) The Escrow Agent shall be obligated to perform only such duties and obligations as are specifically set forth herein and may rely and
shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties in accordance with the terms of this Agreement. The Escrow Agent shall
not be liable for forgeries or false impersonations. The Escrow Agent shall not be liable for any act done or omitted hereunder as escrow agent, except for gross negligence, willful misconduct or breach of this Agreement. The Escrow Agent shall in
no case or event be liable for any representations or warranties of Parent or the Company Shareholders for punitive, incidental or consequential damages. Any act done or omitted pursuant to the advice or opinion of counsel shall be conclusive
evidence of the good faith of the Escrow Agent. 
 (b) In the event of a dispute between the parties hereto, the Escrow Agent
is hereby expressly authorized to disregard any and all notifications given by any of the parties hereto or by any other person, excepting only a Resolved Claim Notice or a joint written instruction contemplated by Section 2(c) hereof on
which the Escrow Agent shall be entitled to conclusively rely and shall distribute the Escrow Fund in accordance with the terms thereof, and is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case
the Escrow Agent obeys or complies with any such order, judgment or decree of any court, the Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment,
or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction. 
 (c) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver the Merger Agreement, this Agreement or any documents or
papers deposited or called for thereunder or hereunder.

rights under any statute of limitations with respect to the Merger Agreement, this Agreement or any documents deposited with the Escrow Agent. 
 7. Resignation and Removal of the Escrow Agent. 
 (a) The Escrow Agent may resign as escrow agent hereunder
at any time, with or without cause, by giving at least thirty (30) days’ prior written notice to each of Parent and the Seller, such resignation to be effective thirty (30) days following the date such notice is received by Parent and
the Seller. In addition, Parent and the Seller may jointly remove the Escrow Agent as escrow agent hereunder at any time, with or without cause, by an delivering an instrument executed by Parent and the Seller (which may be executed in counterparts)

 -6- 

 (b) In the event of any such resignation or removal, a successor escrow agent, which
shall be a bank or trust company organized under the laws of the United States of America or of the State of Colorado having (or if such bank or trust company is a member of a bank company, its bank holding company shall have) a combined capital and
surplus of not less than $50,000,000, shall be jointly appointed by Parent and the Seller on the terms and conditions of this Agreement. Any such successor escrow agent shall deliver to Parent and the Seller a written instrument accepting such
appointment, and thereupon it shall succeed to all the rights and duties of the Escrow Agent hereunder and shall be entitled to receive possession of the Escrow Fund. Upon receipt of the identity of the successor Escrow Agent, the Escrow Agent shall
deliver the Escrow Fund then held hereunder to the successor Escrow Agent. 
 8. Fees. Parent, on the one hand, and the Company
Shareholders, on the other hand in proportion to their respective Pro Rata Portion of Escrowed Stock, shall each pay the Escrow Agent fifty percent (50%) of the Escrow Agent’s fees as set forth on the Fee Schedule attached hereto as
Exhibit A (as may be amended in the event that the Escrow Agent is replaced by a successor pursuant to Section 7 hereof). 
 9. Further Instruments. In the event that the Escrow Agent reasonably requires other or further instruments in connection with its performance of its duties and obligations hereunder, Parent and the Seller shall use their respective
commercially reasonable best efforts to join in furnishing such instruments. 
 10. Disputes. It is understood and agreed that should
any dispute arise with respect to the delivery and/or ownership or right of possession of the cash and/or other property held by the Escrow Agent hereunder, the Escrow Agent is authorized and directed to act in accordance with, and in reliance upon,

in carrying out its duties and obligations under this Agreement, and to reimburse the Escrow Agent for all its costs and expenses (including, without limitation, counsel fees and expenses) reasonably incurred by reason of any matter as to which such
indemnity is paid pursuant to this Section 11; provided, however, that no indemnity need be paid in case of the Escrow Agent’s gross negligence, willful misconduct or breach of this Agreement.

 or to such other address as any party may have furnished in writing to the other parties in the manner provided above. Any notice addressed to the Escrow Agent shall be

 (b) Amendment and Termination. This Agreement may be amended or terminated if, but
only if, such amendment or termination is in writing and is signed by each of Parent and the Seller, and upon written notice to the Escrow Agent at any time given jointly by Parent and the Seller, but the duties and responsibilities of the Escrow
Agent may not be amended or modified without its consent. 
 (c) Waiver. Any term or condition of this Agreement
may be waived at any time by the party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the party waiving such term or condition. No waiver by
any party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion. All remedies, either under this
Agreement or by Law or otherwise afforded, will be cumulative and not alternative. 
 (d) No Assignment; Binding
Effect. This Agreement shall inure to the benefit of and shall be binding upon the parties hereto and their respective successors and permitted assigns. No provision of this Agreement is intended or shall be construed to confer upon any
entity or Person other than the parties hereto and their respective successors and permitted assigns any right, remedy or claim under or by reason of this Agreement or any part hereof. This Agreement may not be assigned by any of the parties hereto;
provided, however, that Parent may assign all or part of its rights under this Agreement and delegate all or part of its obligations under this Agreement to (i) a wholly owned Subsidiary of Parent, in which event all of the rights and
powers of Parent and remedies available to Parent under this Agreement shall extend to and be enforceable by such Subsidiary, or (ii) any Person who acquires Parent, whether by way of merger or the purchase of all of Parent’s outstanding
capital stock or substantially all of Parent’s assets, provided further in the case of the foregoing clauses (i) and (ii), Parent shall remain fully and primarily obligated hereunder. In the event of any such assignment and delegation, the
term “Parent” as used in this Agreement shall be deemed to refer to such Subsidiary or successor of Parent, as the case may be, where reference is made with respect to actions to be taken with respect to the transactions contemplated by
this Agreement, and 

  

 -9- 

 
shall be deemed to include both Parent and such Subsidiary or successor of Parent, as the case may be, where appropriate. 
 (e) Headings. The headings used in this Agreement have been inserted for convenience of reference only and do not define or
limit the provisions hereof. 
 (f) Severability. Any term or provision of this Agreement which is invalid or
unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the
validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broadly as is
enforceable. 
 (g) Governing Law. This Agreement, the legal relations between the parties and the adjudication
and the enforcement thereof, shall be governed by and interpreted and construed in accordance with the substantive laws of the State of Delaware without regard to applicable choice of law provisions thereof. 
 (h) Construction. The parties hereto agree that this Agreement is the product of negotiation between sophisticated parties and
individuals, all of whom were represented by counsel, and each of whom had an opportunity to participate in and did participate in the drafting of each provision hereof. Accordingly, ambiguities in this Agreement, if any, shall not be construed
strictly or in favor of or against any party hereto but rather shall be given a fair and reasonable construction without regard to the rule of contra proferentem. 
 (i) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of
which taken together shall constitute one and the same agreement, it being understood that all of the parties need not sign the same counterpart. 
 (j) Entire Agreement. This Agreement constitutes the entire agreement between the Escrow Agent, on the one hand, and Parent and the Company Shareholders on the other hand, relating to the holding, investment
and disbursement of the Escrow Fund and sets forth in their entirety the obligations and duties of the Escrow Agent with respect to the Escrow Fund, and supersedes all prior agreements and understandings, both written and all with respect to the
subject matter of this Agreement. As between Parent and the Company Shareholders, this Agreement and the Merger Agreement constitute the entire agreement between Parent and the Company Shareholders, it being understood that in the event of a
conflict between this Agreement and the Merger Agreement, the Merger Agreement shall govern. 
 (k) Specific
Performance. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached. It is agreed 

  

 -10- 

 
that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and
provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity. 
 (l) Appointment of Shareholder Agent. Spouse hereby appoints Seller as her agent and attorney-in-fact, with full power of
substitution, to act for and on her behalf in respect of this Agreement. 
 13. Tax Reporting Matters. The Company Shareholders agree
to provide the Escrow Agent with certified tax identification numbers by furnishing appropriate Forms W-9 and other forms and documents that the Escrow Agent may reasonably request to the Escrow Agent within thirty (30) days after the date
hereof. The parties hereto understand that the Escrow Agent will deduct and withhold from any amounts payable or otherwise deliverable to the Company Shareholders or Parent pursuant to this Agreement such amounts as are required to be deducted or
withheld therefrom under any provision of federal, local or foreign Tax law. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such
amounts would otherwise have been paid. 
 14. Patriot Act Compliance. To help the government fight the funding of terrorism and money
laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. For a non-individual person such as a business entity, a charity, a trust or other
legal entity the Escrow Agent will ask for documentation to verify its formation and existence as a legal entity. The Escrow Agent may also ask to see financial statements, licenses, identification and authorization documents from individuals
claiming authority to represent the entity or other relevant documentation. Parent, the Seller and spouse each agree to provide all such information and documentation as to themselves as requested by Escrow Agent to ensure compliance with federal
law.

all Registrable Securities for an offering to be made on a delayed or continuous basis pursuant to Rule 415. The Registration Statement shall be on Form S-3 (except if the Company is not then eligible to register for resale the Registrable
Securities on Form S-3, in which case such registration shall be on another appropriate form in accordance herewith).

Registration Statement continuously effective under the Securities Act until the earlier of (i) the tenth anniversary of the date that the Registration Statement is first declared effective by the Commission and (ii) the date when all

 (e) Notwithstanding anything in this Agreement to the contrary, the Company may, by written notice to the Seller, require
that the Security Holders immediately cease the sale of shares of Common Stock pursuant to the Registration Statement if the Company’s Board of Directors determines in good faith that, due to pending material corporate developments, it is in
the best interests of the shareholders of the Company to suspend the use of the Registration Statement. Upon receipt of such notice, the Security Holders shall immediately discontinue any sales of Registrable Securities pursuant to the Registration
Statement until copies of a supplemented or amended Prospectus and any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus have been made available to the Security Holders on
Commission’s EDGAR database or otherwise, or until the Seller is advised in writing by the Company that the then-current Prospectus may be used. The Company’s rights under this Section 2.1(e) may be exercised for a period of no more
than 45 days at a time and not more than two times in any twelve-month period. 
 2.2 Registration Procedures. In connection with the
Company’s registration obligations hereunder, the Company shall: 
 (a) Not less than three Trading Days prior to the

necessary to keep the Registration Statement continuously effective during the Effectiveness Period; (ii) cause the Prospectus to be amended or supplemented by any necessary prospectus supplement, and as so supplemented or amended to be filed
pursuant to Rule 424; and (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect to the Registration Statement or any amendment thereto and as promptly as reasonably possible provide the
Seller true and complete copies of all correspondence from and to the Commission relating to the Registration Statement. 
 (c) Notify the Seller as promptly as reasonably possible, and (if requested) confirm such notice in writing no later than two Trading Days thereafter, of any of the following events: (i) the Commission notifies the Company whether
there will be a “review” of the Registration Statement; (ii) the Commission comments in writing on the Registration Statement (in which case the Company shall deliver to the Seller a copy 

  

 4 

 
of such comments and of all written responses thereto); (iii) the Registration Statement or any post-effective amendment is declared effective;
(iv) the Commission or any other Federal or state governmental authority requests any amendment or supplement to the Registration Statement or Prospectus or requests additional information related thereto; (v) the Commission issues any
stop order suspending the effectiveness of the Registration Statement or initiates any proceedings for that purpose; (vi) the Company receives notice of any suspension of the qualification or exemption from qualification of the Registrable
Securities for sale in any jurisdiction, or the initiation or threat of any proceeding for such purpose; or (vii) any revision to the Registration Statement or Prospectus as supplemented or amended is required so that it will not contain any
untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
 (d) Use its commercially reasonable efforts to avoid the issuance of or, if issued, obtain the withdrawal of (i) any order suspending
the effectiveness of the Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment. 
 (e) Upon request, make available to the Seller, without charge, at least one conformed copy of the Registration Statement and each
amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference, and all exhibits to the extent requested by the Seller (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the Commission. 
 (f) Promptly deliver to the
Security Holders, without charge, as many copies of the Prospectus and each amendment or supplement thereto as the Security Holders may reasonably request. 
 (g) (i) In the time and manner required by the primary Trading Market, prepare and file with such Trading Market any required additional shares listing application covering all of the Registrable Securities;
(ii) take all commercially reasonable steps necessary to cause such Registrable Securities to be approved for listing on each Trading Market as soon as possible thereafter; (iii) provide to the Seller evidence of such listing; and
(iv) use commercially reasonable efforts to maintain the listing of such Registrable Securities on each such Trading Market or another Eligible Market. 
 (h) Use commercially reasonably efforts to register or qualify or cooperate with the Security Holders in connection with the registration
or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or blue sky laws of such jurisdictions within the United States as the Seller requests in writing, to keep
each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by the Registration Statement; 

  

 5 

 
provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign
corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject. 
 (i) Cooperate with the Security Holders to facilitate the timely preparation and delivery of certificates representing Registrable
Securities to be delivered to a transferee pursuant to the Registration Statement, which certificates shall be free, to the extent permitted by this Agreement and applicable law, of all restrictive legends, and to enable such Registrable Securities
to be in such denominations and registered in such names as the Security Holders may request. 
 (j) Upon the occurrence of
any event described in Section 2.2(c)(vii), as promptly as reasonably possible, prepare a supplement or amendment, including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference, and file any other required document so that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading and that the Prospectus, as thereafter delivered will not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading. 
 2.3 Obligations of the Security Holders. Each Security
Holder agrees that he or she will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement. Each Security Holder further
agrees that, upon receipt by Seller of a notice from the Company pursuant to Section 2.1(e) or upon receipt by Seller of notice from the Company of the occurrence of any event of the kind described in Sections 2.2(c)(v), (vi) or (vii), the
Security Holders will discontinue the disposition of Registrable Securities under the Registration Statement until the Security Holders’ receipt of the copies of the supplemented Prospectus and/or amended Registration Statement contemplated by
Section 2.2(j), or until Seller is advised in writing by the Company that the use of the then-current Prospectus may be resumed. The Company may provide appropriate stop orders to enforce the provisions of this Section 2.3. 
 2.4 Registration Expenses. The Company shall pay (or reimburse the Security Holders for) all fees and expenses incident to the performance of the
Company’s obligations under Sections 2.1 and 2.2, including without limitation (a) all registration and filing fees and expenses, including without limitation those related to filings with the Commission and in connection with applicable
state securities or Blue Sky laws, (b) printing expenses (including without limitation expenses of printing certificates for Registrable Securities and of printing prospectuses reasonably requested by the Security Holders), (c) fees and
expenses of counsel of the Company, and (d) all listing fees to be paid by the Company to the Trading Market. Each Security Holder shall be responsible for paying the underwriters’ commission or brokerage fees and taxes of any kind 

  

 6 

 
(including, without limitation, transfer taxes) applicable to any disposition, sale or transfer of Registrable Securities by such Security Holder.

 2.5 Indemnification. 
 (a) Indemnification by the Company. The Company agrees to indemnify and hold harmless the Security Holders against any losses, claims, damages, liabilities or expenses to which the Security Holders may become
subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are
based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any
of them a material fact required to be stated therein or necessary to make the statements in any of them (in the case of the Prospectus only, in light of the circumstances under which they were made), not misleading, and will reimburse the Security
Holders for any legal and other expenses as such expenses are reasonably incurred by the Security Holders in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action;
provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission
or alleged omission made in the Registration Statement, the Prospectus or any amendment or supplement to the Registration Statement or Prospectus in reliance upon and in conformity with written information furnished to the Company by or on behalf of
PDI at or prior to the Closing or a Security Holder expressly for use therein or in any document incorporated by reference therein, (ii) the failure of a Security Holder to comply with the covenants and agreements contained in Section 2.3
of this Agreement, or (iii) any untrue statement or omission of a material fact in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Seller before the pertinent sale or sales by a Security Holder.

 (b) Indemnification by the Security Holders. The Security Holders, jointly and severally, will indemnify and hold
harmless the Company, each of its directors, each of its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act, against any losses, claims, damages, liabilities or
expenses to which the Company, each of its directors, each of its officers who sign the Registration Statement or controlling person may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or
regulation insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon (i) any failure on the part of the Security Holders to comply with the covenants
and agreements contained in Sections 2.3 of this Agreement or (ii) any untrue or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement to the Registration Statement
or Prospectus, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus only, in light of the circumstances under which they were
made), not misleading, in each case to the extent, 

  

 7 

 
but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the
Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of PDI at or prior to the Closing or a Security Holder expressly for use therein or in any
document incorporated by reference therein, and the Security Holders, jointly and severally, will reimburse the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person for any legal and other
expense reasonably incurred by the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim,
damage, liability, expense or action for which such person is entitled to be indemnified in accordance with this Section 2.5(b). 
 (c) Indemnification Procedure. 
 (i) Promptly after receipt by an indemnified party
under this Section 2.5 of notice of the threat or commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 2.5, promptly notify the indemnifying
party in writing of the claim; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this
Section 2.5 except to the extent it is prejudiced as a result of such failure. 
 (ii) In case any such action is brought
against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it may wish, jointly with all other
indemnifying parties similarly notified, to assume the defense thereof; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have
reasonably concluded that there may be a conflict between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it or other indemnified parties
that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel reasonably acceptable to the indemnifying party to assume such legal defenses and to
otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action, the
indemnifying party will not be liable to such indemnified party under this Section 2.5 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless: 
 a) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the
proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, approved by 

  

 8 

 
such indemnifying party representing all of the indemnified parties who are parties to such action), or 
 b) the indemnifying party shall not have engaged counsel to represent the indemnified party (or both the indemnified and indemnifying
party, as applicable) within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel to the indemnified party shall be at the expense of the indemnifying party. 
 (d) Contribution. If a claim for indemnification under this Section 2.5 is unavailable to an indemnified party (by reason of
public policy or otherwise), then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses
referred to in this Agreement, in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified party, respectively, in connection with the actions, statements or omissions that resulted in such losses,
claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in
question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such indemnifying party or indemnified party, and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party under this Section 2.5(d) as a result of any losses, claims,
damages, liabilities or expenses shall be deemed to include, subject to the limitations set forth in this Section 2.5, any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any proceeding
to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. 
 The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. No party to this Agreement guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any other party to this Agreement who was not guilty of such fraudulent misrepresentation. 
 ARTICLE 3. 
 MISCELLANEOUS

hereto shall have any obligation hereunder, if the Merger Agreement is terminated pursuant to its terms prior to the Closing. This Agreement may be terminated at any time by the mutual written consent of the Company and the Security Holders.
