 Exhibit 10.7 
 REGISTRATION RIGHTS AGREEMENT 
 This REGISTRATION RIGHTS AGREEMENT (this
“Agreement”), dated as of January 11, 2007, is by and between Winchester Development LLC (“Holder”) and SkyTerra Communications, Inc., a Delaware corporation (“SkyTerra”).
Certain capitalized terms used herein are defined in Section 7 below. 
 RECITALS: 
 WHEREAS, pursuant to the stock purchase agreement, dated as of January 11, 2007, by and among Holder, SkyTerra and MSV Investors, LLC (the
“Purchase Agreement”), SkyTerra will issue an aggregate of 176,250 shares of its Common Stock (the “Acquired Shares”) to the Holder; 
 WHEREAS, in order to induce the Holder to consummate the transactions under the Purchase Agreement, SkyTerra has agreed to provide certain registration
rights to the Holder on the terms and subject to the conditions set forth herein. 
 NOW, THEREFORE, the parties hereto hereby agree as
follows: 
 SECTION 1. REGISTRATION UNDER THE SECURITIES ACT. 
 1.1 Registration. 
 (a) Each of the
parties to this Agreement shall cooperate, and SkyTerra shall file with the Securities and Exchange Commission (the “SEC”) as soon as practicable following the date hereof, a registration statement (or an amendment to an
existing registration statement of SkyTerra on file with the SEC) on the appropriate form for the purpose of registering the Acquired Shares under the Securities Act for resale by holders of the Acquired Shares (the “Resale Registration
Statement”). SkyTerra will cause the Resale Registration Statement to comply as to form in all material respects with the applicable provisions of the Securities Act and the rules and regulations thereunder. SkyTerra shall use its
commercially reasonable efforts, and the Holder will cooperate with SkyTerra, to have the Resale Registration Statement declared effective by the SEC as promptly as practicable. 
 (b) SkyTerra shall keep the Resale Registration Statement effective (including through the filing of any required post-effective amendments) until the
earlier to occur of (i) such time as the Holder has sold all of the Acquired Shares registered thereunder or (ii) January 5, 2008; provided, that such date shall be extended by the amount of time of any period during which the Holder
may not use the Resale Registration Statement as the result of the occurrence of an event described in Section 1.2(e) (ii), (iii) or (iv) below. Thereafter, SkyTerra shall be entitled to withdraw the Resale Registration Statement and,
upon such withdrawal, the Holder shall have no further right to sell any of the Acquired Shares pursuant to the Resale Registration Statement (or any prospectus forming a part thereof). 

 EXECUTION 
 1.2 Registration Procedures. Subject to the terms and conditions hereof, SkyTerra shall use its commercially reasonable efforts to effect the registration and the disposition of the Acquired Shares in
accordance with the intended method of disposition thereof, and pursuant thereto SkyTerra shall as expeditiously as practicable: 
  

	 	(a)	promptly prepare and file with the SEC the Resale Registration Statement with respect to the Acquired Shares (and any amendments, including any post-effective amendments or
supplements to the Resale Registration Statement SkyTerra deems to be necessary) and use its commercially reasonable efforts to cause the Resale Registration Statement to become effective and to comply with the provisions of the Securities Act
applicable to it; provided, that before filing the Resale Registration Statement or prospectus or any amendments or supplements thereto, SkyTerra shall furnish to counsel for the Holder copies of all such documents proposed to be filed,
including documents incorporated by reference in the Registration Statement and, if requested by the Holder, the exhibits incorporated by reference so as to provide the Holder and its counsel a reasonable opportunity to review and comment on such
documents, and SkyTerra (i) will make such changes and additions thereto as reasonably requested by counsel to the Holder prior to filing the Resale Registration Statement or amendment thereto or any prospectus or any supplement thereto and
(ii) if the Holder is an underwriter or controlling person of SkyTerra, will include therein material relating to the Holder or the plan of distribution for the Acquired Shares registered thereunder, furnished to SkyTerra in writing, which, in
the reasonable judgment of the Holder, should be included; 

  

	 	(b)	furnish to the Holder such number of copies of the Resale Registration Statement, each amendment and supplement thereto, the prospectus included in the Resale Registration Statement
and such other documents as the Holder may reasonably request in order to facilitate the disposition of the Acquired Shares registered thereunder; provided, however, that SkyTerra shall have no obligation to furnish copies of a final
prospectus if the conditions of Rule 172(c) under the Securities Act are satisfied by SkyTerra; 

  

	 	(c)	prepare and file with the SEC such amendments and supplements to the Resale Registration Statement and the prospectus used in connection therewith as may be necessary to keep the
Resale Registration Statement effective for the time period as specified in Section 1.1 in order to complete the disposition of the Acquired Shares covered by the Resale Registration Statement and comply with the provisions of the Securities
Act with respect to the disposition of all Acquired Shares covered by the Resale Registration Statement during such period in accordance with the intended methods of disposition thereof as set forth in the Resale Registration Statement;

  

	 	(d)	 use its commercially reasonable efforts to register or qualify the Acquired Shares under such other securities or blue sky laws of such jurisdictions as the Holder
reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable the Holder to consummate the disposition of the Acquired Shares in such jurisdictions (provided that SkyTerra shall not be required
to (i) qualify generally to do business in any jurisdiction where 

  

 -2- 

 EXECUTION 
 it would not otherwise be required to qualify but for this subsection, (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction);

  

	 	(e)	notify the Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, (i) when the Resale Registration Statement or any
post-effective amendment has become effective under the Securities Act, (ii) of any written request by the SEC for amendments or supplements to the Resale Registration Statement or prospectus, (iii) of the happening of any event as a
result of which the prospectus included in the Resale Registration Statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein, in light of the circumstances under which they were made, not
misleading (whereupon the Holder shall immediately cease any offers, sales or other distribution of Acquired Shares registered thereunder), and, subject to 1.3(c), SkyTerra shall promptly prepare a supplement or amendment to such prospectus so that,
as thereafter used by the Holder for the resale of the Acquired Shares, such prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and (iv) of the issuance of any stop order suspending the effectiveness of the Resale Registration Statement, or of any order suspending or preventing the use of any related prospectus or suspending the
qualification of any of the Acquired Shares included in the Resale Registration Statement for sale or distribution in any jurisdiction; 

  

	 	(f)	in the event of the issuance of any stop order suspending the effectiveness of the Resale Registration Statement, or of any order suspending or preventing the use of any related
prospectus or suspending the qualification of any Acquired Shares included in the Resale Registration Statement for sale or distribution in any jurisdiction, SkyTerra shall use its commercially reasonable efforts promptly to obtain the withdrawal of
such order and shall prepare and file an amended or supplemented prospectus, if required; and 

  

	 	(g)	provide a transfer agent and registrar for all the Acquired Shares not later than the effective date of the Resale Registration Statement; 

  

	 	(h)	use its commercially reasonable efforts to cause the Acquired Shares covered by the Resale Registration Statement to be registered with or approved by such other governmental
agencies or authorities as may be necessary to enable the Holder to complete the disposition of the Acquired Shares covered by the Registration Statement and comply with the provisions of the Securities Act with respect to the disposition of all
Acquired Shares covered by the Resale Registration Statement during such period in accordance with the intended methods of disposition by the Holder thereof set forth in the Resale Registration Statement; and 

  

	 	(i)	 make available for inspection by the Holder, any underwriter participating in any disposition pursuant to the Resale Registration Statement on behalf of the Holder,
and any attorney, accountant or other agent retained by the Holder or the 

  

 -3- 

 EXECUTION 
 underwriter, all financial and other records, pertinent corporate documents and properties of SkyTerra, and cause SkyTerra’s officers, managers, employees and independent accountants to supply all information
reasonably requested by the Holder and such underwriters, attorneys, accountants or agents in connection with the Resale Registration Statement. 
 1.3 Other Procedural Matters. 
  

	 	(a)	SEC Correspondence. SkyTerra shall make available to the Holder promptly after the same is prepared and publicly distributed, filed with the SEC, or received by SkyTerra, one
copy of the Resale Registration Statement and any amendment thereto, each preliminary prospectus and each amendment or supplement thereto, each letter written by or on behalf of SkyTerra to the SEC or the staff of the SEC (or other governmental
agency or self-regulatory body or other body having jurisdiction, including any domestic or foreign securities exchange), in each case relating to the Resale Registration Statement. SkyTerra will promptly respond to any and all comments received
from the SEC, with a view towards causing the Resale Registration Statement or any amendment thereto to be declared effective by the SEC as soon as practicable and shall file an acceleration request as soon as practicable following the resolution or
clearance of all SEC comments or, if applicable, following notification by the SEC that the Resale Registration Statement or any amendment thereto will not be subject to review. 

  

	 	(b)	SkyTerra may require the Holder to furnish to SkyTerra any other information regarding the Holder and the disposition of the Acquired Shares, including without limitation the plan
of distribution of the Acquired Shares, as SkyTerra reasonably determines, is required to be included in the Resale Registration Statement. 

  

	 	(c)	The Holder agrees that, upon notice from SkyTerra of the happening of any event as a result of which the prospectus included in the Resale Registration Statement contains an untrue
statement of a material fact or omits any material fact necessary to make the statements therein not misleading (a “Suspension Notice”), such Holder will forthwith discontinue disposition of Acquired Shares pursuant to the
Resale Registration Statement until the Holder is advised in writing by SkyTerra that the use of the prospectus may be resumed and are furnished with a supplemented or amended prospectus as contemplated by Section 1.2 hereof; provided,
however, that such postponement of sales of Acquired Shares by the Holder shall not in any event exceed (i) twenty (20) consecutive days or (ii) forty-five (45) days in the aggregate in any 12 month period. If SkyTerra
shall give the Holder any Suspension Notice, SkyTerra shall extend the period of time during which SkyTerra is required to maintain the Resale Registration Statement effective pursuant to this Agreement by the number of days during the period from
and including the date of the giving of such Suspension Notice to and including the date the Holder is advised by SkyTerra that the use of the prospectus may be resumed. In any event, SkyTerra shall not be entitled to deliver more than a total of
three (3) Suspension Notices in any 12 month period.

 EXECUTION 
  

	 	(d)	Neither SkyTerra nor the Holder shall permit any officer, manager, underwriter, broker or any other person acting on behalf of SkyTerra to use any free writing prospectus (as
defined in Rule 405 under the Securities Act) in connection with the Resale Registration Statement filed pursuant to this Agreement without the prior written consent of SkyTerra, the Holder and any underwriter. 

 1.4 Expenses. 
  

	 	(a)	Registration Expenses. All Registration Expenses shall be borne by SkyTerra. 

  

	 	(b)	Selling Expenses. All expenses incident to the Holder’s performance of or compliance with this Agreement, including, without limitation, all fees and expenses of counsel
for the Holder, fees and expenses of the Holder’s transfer agent, and any broker or dealer discounts or commissions attributable to the disposition of Acquired Shares shall be borne solely by the Holder, as incurred by each or on a pro rata
basis for shared expenses, as applicable. 

 SECTION 2. LOCKUP AGREEMENT. 
 2.1 The Holder hereby agrees to not effect any public sale or distribution (including any sales pursuant to Rule 144) of equity securities of
SkyTerra, or any securities convertible into or exchangeable or exercisable for such securities, during the seven days prior to and the 90-day period beginning on the effective date of any underwritten registered public offering of equity securities
of SkyTerra or securities convertible or exchangeable into or exercisable for equity securities of SkyTerra (except as part of such underwritten registration), unless the underwriters managing the registered public offering otherwise consent in
writing, and the Holder will deliver an undertaking to the managing underwriters (if requested) consistent with this covenant. The Holder shall not be obligated to comply with the provisions of this Section 2.1 more than two times in any
12-month period. 
 SECTION 3. INDEMNIFICATION. 
 3.1 Indemnification by SkyTerra. SkyTerra agrees to indemnify, to the extent permitted by law, the Holder against all losses, claims, damages, liabilities, and expenses caused by any untrue or alleged untrue
statement of material fact contained in the Resale Registration Statement or any prospectus forming a part of the Resale Registration Statement or any “issuer free writing prospectus” (as defined in Securities Act Rule 433), or any
amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or any
violation or alleged violation by SkyTerra of the Securities Act, the Exchange Act or applicable “blue sky” laws, except insofar as the same are made in reliance and in conformity with any information furnished in writing to SkyTerra by
the Holder expressly for use therein or by the failure of the Holder to deliver a copy of such registration statement or prospectus or any amendments or supplements thereto as required by law after SkyTerra has furnished the Holder with a sufficient
number of copies of the same. 
  

 -5- 

 EXECUTION 
 3.2 Indemnification by the Holder. In connection with the Resale Registration Statement in which the Holder is participating, the Holder shall furnish to SkyTerra in writing such information as SkyTerra
reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, the Holder shall indemnify SkyTerra, its directors, officers, employees and Affiliates, and each Person who controls
SkyTerra (within the meaning of the Securities Act), against any losses, claims, damages, liabilities, and expenses resulting from any untrue or alleged untrue statement of material fact contained in the Resale Registration Statement, the prospectus
or preliminary prospectus forming a part of the Resale Registration Statement or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading, but only to the extent that any information so furnished in writing by such Holder contains such untrue statement or omits a material fact required to be stated
therein necessary to make the statements therein not misleading; provided, however, that the obligation of the Holder to indemnify SkyTerra hereunder shall be limited to the net proceeds to such Holder from the sale of such
Holder’s Acquired Shares pursuant to the Resale Registration Statement. 
 3.3 Indemnification Procedures. Any Person entitled to
indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to
indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may
exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any
liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be
obligated to pay the fees and expenses of more than one counsel (in addition to local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be
one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another indemnified party with respect to such claim. Failure to give prompt written notice shall not release
the indemnifying party from its obligations hereunder. 
 3.4 Investigation; Contribution. The indemnification provided for under this
Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, or controlling Person of such indemnified party and shall survive the transfer of securities. If
the indemnification provided under Section 3.1 or Section 3.2 of this Agreement is held by a court to be unavailable or unenforceable in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each
applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified Person as a result of such losses, claims, damages, liabilities or expenses in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that result in such losses, claims, damages, liabilities or expenses as well
as any other relevant equitable considerations. The relative fault of the indemnifying party on the one hand and 

  

 -6- 

 EXECUTION 
 of
the indemnified Person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party, and by such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. In no event shall the liability of the
Holder for contribution pursuant to this Section 3.4 be greater than the amount for which the Holder would have been liable pursuant to Section 3.2 had indemnification been available and enforceable. 
 SECTION 4. RULE 144 TRANSACTIONS. 
 4.1 Undertaking to File Reports and Cooperate in Rule 144 Transactions. For as long as the Holder continues to hold any Acquired Shares, SkyTerra shall use its commercially reasonable efforts to file with the SEC, on a timely basis,
all annual, quarterly and other periodic reports required to be filed by it under Sections 13 and 15(d) of the Exchange Act, and the rules and regulations thereunder; provided, however, that the foregoing shall not be construed to
require SkyTerra to prepare and file periodic reports if it is not required to do so under the Exchange Act. In the event of any proposed sale by the Holder of Acquired Shares pursuant to Rule 144 under the Securities Act or otherwise as provided
herein, which sale is to be made in accordance with the terms of Section 5.1(b) hereof, SkyTerra shall use its commercially reasonable efforts to cooperate with the Holder so as to enable such sales to be made in accordance with applicable
laws, rules and regulations, the requirements of the transfer agent of SkyTerra, and the reasonable requirements of the broker through which the sales are proposed to be executed, and shall, upon written request, furnish unlegended certificates
representing ownership of Acquired Shares sold thereby, such certificates to be furnished in such numbers and denominations as the Holder may reasonably request. 
 SECTION 5. RESTRICTIONS ON TRANSFER. 
 5.1 Permitted Transfers. The Holder hereby agrees
that, until it and any permitted transferees under paragraph (e) hereunder have disposed of all of the Acquired Shares, it will not, directly or indirectly, without the prior written consent of SkyTerra, sell, distribute, transfer or otherwise
dispose (in each case, a “Disposition”) of any Acquired Shares except:

Acquired Shares consisting of, in the aggregate, more than five percent (5%) of the total combined voting power of all Acquired Shares then outstanding; provided, however, that in each such case, the transferee shall receive and hold such
Acquired Shares subject to, and the transferee and all of the transferees’ Affiliates shall agree to be bound by, all the terms of this Agreement, which terms shall also inure to the benefit of such transferees, and there shall be no further
transfer of such Acquired Shares, except in accordance with the provisions of this Section 5.1; or

writing that it has received a copy of this Agreement and agrees, upon its becoming the owner of, or obtaining dispositive authority with respect to or in connection with any disposition of, any such Acquired Shares, to be bound by the provisions of
this Agreement in connection with any right it may have to dispose of any such Acquired Shares (and, upon agreeing so to be bound, the provisions of this Agreement shall inure to the benefit of such party); or 

  

	 	(e)	sales or transfers of Acquired Shares pursuant to a tender or exchange offer which the Board of Directors of SkyTerra does not oppose within 10 business days after the date of
commencement (as such term is defined in Rule 14d-2(a) of the General Rules and Regulations under the Exchange Act) of such offer; or 

  

	 	(f)	dispositions pursuant to any merger, consolidation, reorganization or recapitalization to which SkyTerra is a party or in connection with any reclassification of Acquired Shares.

 provided, that in the event that any Seller seeks to effect a Disposition of any Acquired Shares pursuant to clauses (b) or (c) of
this Section 5.1, (i) such Disposition is made in compliance with applicable securities laws, and (ii) prior to such Disposition, such Seller shall have delivered to SkyTerra an opinion of counsel stating that such Disposition
(A) is permitted by this Agreement and the Purchase Agreement on Schedule A hereto, (B) does not require registration under the Securities Act, and (C) does not cause the Purchase Agreement to be required to have been registered under
the Securities Act and that this Agreement is enforceable against the transferee of such Acquired Shares.

 SECTION 2. Buyer’s Representations and Warranties. The
Buyer represents and warrants to the Company that as of the date hereof, and as of the Closing Date: 
 (a) Investment Purpose. The
Buyer is acquiring the Notes for its own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof; provided, however, that by making the representations herein, the Buyer does
not agree to hold any of the Notes or the shares of Common Stock issued upon conversion of the Notes, including any Additional Shares (as defined in the Indenture) (collectively, the “Conversion Shares” and, together with the Notes, the
“Securities”) for any minimum or other specific term and reserves the right to dispose of the Securities at any time; provided, further, that Buyer agrees that such disposition shall be in accordance with or pursuant to a registration
statement or an exemption under the Securities Act. The Buyer is not a registered broker-dealer. The Buyer is purchasing the Securities in the ordinary course of business, and has no agreement or understanding, directly or indirectly, with any
person to distribute the Securities. 
 (b) Accredited Investor and Qualified Institutional Buyer Status. The Buyer is an
“accredited investor” as that term is defined in Rule 501(a) of Regulation D under the Securities Act and a “qualified institutional buyer” as that term is defined in Rule 144A(a) under the Securities Act as of the date of this
Agreement and was not organized for the specific purpose of acquiring the Securities. 
 (c) Reliance on Exemptions. The Buyer
understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy
of, and the Buyer’s compliance with, the representations, warranties, covenants, agreements, acknowledgments and understandings of the Buyer set forth herein and in the applicable Note in order to determine the availability of such exemptions

the Offering, (iii) has had access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment, (iv) can bear the
economic risk of a total loss of its investment in the Securities and (v) has such knowledge and experience in business and financial matters so as to enable it to understand the risks of and form an investment decision with respect to its
investment in the Securities. Neither such inquiries nor any other due diligence investigations conducted by the Buyer or its advisors, if any, or its representatives shall limit, modify, amend or affect the Company’s representations and
warranties contained in this Agreement or any other Transaction Document and the Buyer’s right to rely thereon. 
 (e) No
Governmental Review. The Buyer understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of
the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities. 
 (f)
Transfer or Resale. The Buyer understands that the Notes and, upon issuance, the Conversion Shares, shall constitute “restricted securities” under Rule 144 of the Securities Act. The Buyer also understands that, except as provided
in the Registration Rights Agreement, the Securities have not been and will not be registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred without registration under the
Securities Act or an exemption therefrom and that, in the absence of an effective registration statement under the Securities Act, such Securities may only be sold under certain circumstances as set forth in the Securities Act. In that connection,
the Buyer is aware of Rule 144 and Rule 144A under the Securities Act and the restrictions imposed thereby. 
 (g) Authorization;
Enforcement; Validity. The Buyer is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite corporate or partnership power and authority to enter into and to
consummate the transactions contemplated by this Agreement, the Registration Rights Agreement and otherwise to carry out its obligations hereunder and thereunder. The execution, delivery and performance by the Buyer of the transactions contemplated
by this Agreement has been duly authorized by all necessary corporate action on the part of the Buyer. This Agreement and the Registration Rights Agreement have been duly executed by the Buyer, and when delivered by the Buyer in accordance with
terms hereof, will constitute the valid and legally binding obligation of the Buyer, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application. 
 (h) Residency. The Buyer is a resident of Cayman Islands. 

 (i) No Conflicts. The execution and performance of this Agreement and the Registration Rights
Agreement do not conflict with any agreement to which the Buyer is a party or is bound thereby, any court order or judgment addressed to the Buyer, or the constituent documents of the Buyer except for such conflicts which would not, individually or
in the aggregate, have a material adverse effect on the Buyer’s authority or ability to perform its obligations under this Agreement or the Registration Rights Agreement. 
 (j) Additional Acknowledgement. The Buyer acknowledges that it has independently evaluated the merits of the transactions contemplated by the
Transaction Documents, that it has independently determined to enter into the transactions contemplated hereby and thereby. The Buyer acknowledges and agrees that it is acting solely in the capacity of arm’s length purchaser with respect to the
Transaction Documents and the transactions contemplated hereby and thereby and that it is not (i) an officer or director of the Company, (ii) to the knowledge of the Buyer, an “affiliate” of the Company (as defined in Rule 144)
or (iii) a “beneficial owner” of more than 10% of the Common Stock (as defined for purposes of Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). The Buyer acknowledges and agrees that the
Company makes no representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 3. 
 (k) General Solicitation. The Buyer is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or
similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement. 
 (l) Certain Trading Activities. The Buyer has not directly or indirectly, nor has any person acting on behalf of or pursuant to any understanding with the Buyer, engaged in any transactions in the securities of the Company
(including, without limitations, any Short Sales (as defined below) involving the Company’s securities) since the time that the Buyer was first contacted by the Company or Piper Jaffray (as defined below) regarding an investment in the Company.
The Buyer covenants that neither it nor any person acting on its behalf or pursuant to any understanding with it will engage in any transactions in the securities of the Company (including Short Sales) prior to the time that the transactions

 SECTION 3. Representations and Warranties of the Company. The Company represents and warrants to the Buyer that, except as
set forth in the Disclosure Schedule delivered concurrently to Buyer (the “Disclosure Schedule”), as of the date hereof and as of the Closing Date: 
 (a) Organization and Qualification. The Company is a corporation duly organized and validly existing in good standing under the laws of the State of Delaware, and has the requisite corporate power and

Adverse Effect. Copies of the Company’s Certificate of Incorporation and Bylaws, and all amendments thereto, have been filed as exhibits to the
Company’s SEC Documents (as defined in Section 3(f) of this Agreement), are in full effect and have not been modified. The Company is duly qualified as a foreign corporation to do business and is in good standing in every jurisdiction in
which its ownership of property or the nature of the business conducted and proposed to be conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not have a Material

Company, taken as a whole, (ii) the transactions contemplated hereby or by the agreements and instruments to be entered into in connection herewith, or (iii) the authority or ability of the Company to perform its obligations under the

Conversion Shares issuable upon conversion thereof and the registration for resale of the Registrable Securities (as such term is defined in the Registration Rights Agreement), have been duly authorized by the Company’s Board of Directors and
(other than the filing with the Commission of one or more registration statements in accordance with the requirements of the Registration Rights Agreement) no further filing, consent or authorization is required of the Company, Company’s Board
of Directors or shareholders. The Transaction Documents have been duly executed and delivered by the Company. The Transaction Documents constitute the valid and binding obligations of the Company enforceable against the Company in accordance with
their terms, except (i) as rights to indemnification and contribution may be limited by federal or state securities laws and policies underlying such laws and (ii) as such enforceability may be limited by general principles of equity or
applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of creditors’ rights and remedies. 
 (c) Capitalization. Except for any shares issuable upon exercise of options issued pursuant to employee benefit or other plans disclosed in
Section 3(c) of the Disclosure Schedule, the capitalization of the Company is as described in Section 3(c) of the Disclosure Schedule. All of the Company’s outstanding shares have been validly issued and are fully paid and
nonassessable and were issued in accordance with applicable federal and state securities laws. The Company’s Common Stock is registered pursuant to Section 12(b) of the Exchange Act and is listed for trading on The NASDAQ Global Market
(the “Principal Market”). Except for rights created pursuant to the Transaction Documents or as set forth in Section 3(c) of the Disclosure Schedule, (i) no shares of the Company’s capital stock are subject to preemptive
rights or any other similar rights or any liens or encumbrances created by the Company; (ii) there are no outstanding options, warrants, scrip, rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities

evidencing indebtedness of the Company or by which the Company is or may become bound; (iv) there are no amounts outstanding under, and there will be no amounts due upon termination of, any credit agreement or credit facility; (v) there
are no agreements or arrangements under which the Company is obligated to register the sale of any of its securities under the Securities Act; (vi) there are no outstanding securities or instruments of the Company which contain any redemption
or similar provisions, and there are no contracts, commitments, understandings or arrangements by which the Company is or may become bound to redeem a security of the Company; (vii) there are no securities or instruments containing
anti-dilution or similar provisions that will be triggered by the issuance of the Securities as described in this Agreement; (viii) there are no financing statements securing obligations in any material amounts, either singly or in the
aggregate, filed in connection with the Company; (ix) the Company does not have any stock appreciation rights or “phantom” stock plans or agreements or any similar plan or agreement; (x) the Company have no liabilities or
obligations required to be disclosed in the SEC Documents but not so disclosed in the SEC Documents, other than those incurred in the ordinary course of the Company’s business and which, individually or in the aggregate, do not or would not
have a Material Adverse Effect on the Company taken as a whole; and (xi) the Company does not have outstanding stockholder purchase rights or “poison pill” or any similar arrangement in effect giving any person or entity the right to
purchase any equity interest in the Company upon the occurrence of certain events. 
 (d) Issuance of Securities. The Securities are
duly authorized and, upon issuance in accordance with the terms of the applicable Transaction Documents, shall be (i) validly issued, fully paid and non-assessable and (ii) free from all taxes, liens and charges with respect to the
issuance thereof, other than any liens or encumbrances created by or imposed by the Buyer, and shall not be subject to preemptive rights or other similar rights of shareholders of the Company. As of the Closing, at least 13,251,762 shares of Common
Stock (subject to adjustment pursuant to the Company’s covenant set forth in Section 4(d) of this Agreement) will have been duly authorized and reserved for issuance (i) upon conversion of the Notes and (ii) upon issuance of
Additional Shares pursuant to the terms of the Indenture. Upon issuance of the Notes in accordance with this Agreement and conversion or issuance in accordance with the terms of the Notes and the Indenture, the Conversion Shares will be validly
issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to the issue thereof, other than any liens or encumbrances created by or imposed by the Buyer, with the holders being entitled to all rights accorded to a
holder of Common Stock. Subject to the accuracy of the representations and warranties of the Buyer in this Agreement, the issuance by the Company of the Securities is exempt from registration under the Securities Act and applicable state securities
laws. 
 (e) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by
the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Notes and 

 
the reservation for issuance and issuance of the Conversion Shares) will not (i) result in a violation of the Company’s Certificate of
Incorporation or Bylaws; (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of,
any agreement, indenture or instrument to which the Company is a party, except for such conflicts, defaults, terminations, amendments, accelerations, cancellations and violations as would not, individually or in the aggregate, have a Material
Adverse Effect or which have been waived in writing; or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations and the rules and regulations of the
Principal Market) applicable to the Company or by which any property or asset of the Company is bound or affected except as would not, individually or in the aggregate, result in a Material Adverse Effect. The Company is not in violation of any
material term of or in default under its Certificate of Incorporation or Bylaws. The Company is not in violation of any term of or in default under any contract, agreement, mortgage, indebtedness, indenture, instrument, judgment, decree or order or
any statute, rule or regulation applicable to the Company, except where such violations and defaults would not result, either individually or in the aggregate, in a Material Adverse Effect. The business of the Company is not being conducted in
violation of any law, ordinance or regulation of any governmental entity, except where such violations would not result, either individually or in the aggregate, in a Material Adverse Effect. Except as specifically contemplated by this Agreement, as
required under the Securities Act or as required by Blue Sky filings (but only to the extent that such filings may be made after the Closing), the Company is not required to obtain any consent, authorization or order of, or make any filing or
registration with, any court or governmental agency or any regulatory or self-regulatory agency or other person or entity in order for it to execute, deliver or perform any of its obligations under or contemplated by the Transaction Documents. All
consents, authorizations, orders, filings and registrations which the Company is required to obtain pursuant to the preceding sentence have been obtained or effected on or prior to the date hereof and copies of such consents, authorizations, orders,
filings and registrations have been delivered to the Buyer. The Company is not in violation of the listing requirements of the Principal Market, has no actual knowledge of any facts which could reasonably lead to delisting or suspension of the
Common Stock by the Principal Market in the foreseeable future and since December 31, 2005, the Common Stock has been designated for quotation on the Principal Market. The Company is not in violation of any covenants or other terms of its
outstanding indebtedness for borrowed money, which could reasonably be expected to have a Material Adverse Effect. To the knowledge of the Company, there are no facts or circumstances which are reasonably likely to give rise to any of the foregoing
events set forth in this paragraph. 
 (f) SEC Documents; Financial Statements. For the two (2) years preceding the date hereof,
the Company has filed all reports, schedules, forms, statements and other documents required to be filed by it with the Commission pursuant to the reporting requirements of the Exchange Act (all of the foregoing filed prior to or on the date hereof
and all exhibits included therein and financial statements and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC Documents”). The Company has delivered to the Buyer or its
representatives true, correct and complete copies of each of the SEC Documents not available on the EDGAR system. As of the date of filing of such SEC Documents, each such SEC Document, as it may have been subsequently amended by filings made by the
Company with the Commission prior to the date hereof, complied in all material 

 
respects with the requirements of the Exchange Act applicable to such SEC Document and did not contain any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements therein, in light of the circumstances under which they are or were made, not misleading. As of their respective dates, as amended, the financial statements of the Company included in
the SEC Documents complied as to form in all material respects with applicable accounting requirements and published rules and regulations of the Commission with respect thereto. Such financial statements, as amended, have been prepared in
accordance with generally accepted accounting principles, consistently applied in the United States (“GAAP”), during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or
(ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements), correspond to the books and records of the Company and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of operations and cash flows for the periods then ended. PriceWaterhouseCoopers LLP are independent public accountants as required by the Exchange Act. The Company is not aware of any
issues raised by the Commission with respect to any of the SEC Documents. No other written information provided by or on behalf of the Company to the Buyer which is not included in the SEC Documents, including, without limitation, information
referred to in Section 2(d) of this Agreement, contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they are or
were made, not misleading. The Company is not required to file and will not be required to file, any agreement, note, lease, mortgage, deed or other instrument entered into prior to the date hereof and to which the Company is a party or by which the
Company is bound which has not been previously filed as an exhibit to its reports filed with the Commission under the Exchange Act or described in a Current Report on Form 8-K filed by the Company. Except for the issuance of the Notes contemplated
by this Agreement, no event, liability, development or circumstance has occurred or exists with respect to the Company or its business, properties, operations or financial condition, that is required to be disclosed by the Company under applicable
securities laws and which has not been publicly disclosed. The Company has no reason to believe that its independent auditors will withhold their consent to the inclusion of their audit opinion concerning the Company’s financial statements
which shall be included in the Registration Statement (as such term is defined in the Registration Rights Agreement). 
 (g) Absence of
Litigation. Except as disclosed in Section 3(g) of the Disclosure Schedule, there is no action, suit, proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or body pending
or, to the knowledge of the Company, threatened in writing against the Company or any of the Company’s officers or directors in their capacities as such that would have a Material Adverse Effect. 
 (h) No Integrated Offering. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has, directly or
indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the
Securities Act or any applicable shareholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated,
nor will the Company take 

 any action or steps that would cause the offering of the Securities to be integrated with other offerings. 
 (i) Intellectual Property Rights. The Company possesses, licenses or can acquire or make use of on reasonable terms, adequate rights or licenses
to use all trademarks, trade names, trade dress, service marks, service mark registrations, service names, patents, patent rights, copyrights, inventions, technology licenses, approvals, governmental authorizations, trade secrets, and other
intellectual property rights (collectively, “Intellectual Property”) necessary to conduct its businesses as now conducted and as currently contemplated to be conducted by them as described in the SEC Documents, except where the failure to
currently own or possess Intellectual Property would not have a Material Adverse Effect. The Company does not have any knowledge of any infringement by the Company of Intellectual Property rights of others, or of any development of similar or
identical trade secrets or technical information by others, except where such infringement would not have a Material Adverse Effect. There is no claim, action or proceeding being made by the Company regarding the Intellectual Property rights of the
Company or to the Company’s knowledge, brought or currently threatened against the Company regarding the Intellectual Property rights of or the use of any Intellectual Property by the Company of any third party that, if the subject of an
unfavorable decision, ruling or finding, would have a Material Adverse Effect. 
 (j) Brokers and Finders. The Company shall be
responsible for the payment of any placement agent’s fees, financial advisory fees, or brokers’ commissions (other than for Persons engaged by the Buyer) relating to or arising out of the transactions contemplated hereby. Except for fees
payable to Piper Jaffray & Co., the exclusive placement agent engaged by the Company with respect to the offer and sale of the Notes (“Piper Jaffray”) as placement agent, no brokers, finders or financial advisory fees or
commissions will be payable by the Company with respect to the transactions contemplated by this Agreement. 
 (k) Absence of Certain
Changes. Except as disclosed in the SEC Documents available on the EDGAR system, since December 31, 2005, there has been no change or development that has had or could reasonably be expected to have, either individually or in the aggregate,
a Material Adverse Effect. Since December 31, 2005, the Company has not (i) declared or paid any dividends, (ii) sold any assets, individually or in the aggregate, in excess of $1,000,000 outside of the ordinary course of business or
(iii) had capital expenditures, individually or in the aggregate, in excess of $1,000,000. The Company has not taken any steps to seek protection pursuant to any bankruptcy law and the Company does not have any knowledge or reason to believe
that its creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so. The Company is not as of the date hereof, and after giving effect to the transactions
contemplated hereby to occur at the Closing, will not be Insolvent (as defined below). For purposes of this Section 3(k), “Insolvent” means, with respect to any Person (i) the present fair saleable value of the such Person’s
assets is less than the amount required to pay such Person’s total Indebtedness (as defined in Section 3(w)), (ii) such Person is unable to pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured, (iii) such Person intends to incur or believes that it will incur debts that would be beyond its ability to pay as such debts mature or (iv) such Person has unreasonably small capital 

 with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be
conducted. 
 (l) No Material Non-Public Information. Except for the issuance of the Securities and the transactions contemplated by
this Agreement and the Company’s intended use of the net proceeds from the sale of the Notes (which such information shall be fully disclosed in the Current Report on Form 8-K filed pursuant to Section 4(f)hereof), the Company has not
provided the Buyer with information that constitutes or could reasonably be expected to constitute material non-public information. The Company understands and confirms that the Buyer will rely on the representations set forth in Section 3 in
effecting transactions in securities of the Company. All disclosure provided to the Buyer regarding the Company, its business and the transactions contemplated hereby, including the Schedules to this Agreement, furnished by or on behalf of the
Company is true and correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not
misleading. Each press release issued by the Company during the twelve (12) months preceding the date of this Agreement did not at the time of release contain any untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading. No event or circumstance has occurred or information exists with respect to the Company or its
businesses, properties, prospects, operations or financial conditions, which, under applicable law, rule or regulation, requires public disclosure or announcement by the Company but which has not been so publicly announced or disclosed. 

(m) Acknowledgment Regarding Buyer’s Purchase of Securities. The Company acknowledges and agrees that the Buyer is acting solely in the
capacity of arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby and that the Buyer is not (i) an officer or director of the Company, (ii) an “affiliate” of
the Company (as defined in Rule 144) or (iii) to the knowledge of the Company, a “beneficial owner” of more than 10% of the shares of Common Stock (as defined for purposes of Rule 13d-3 of the Exchange Act). The Company acknowledges
and agrees that the Buyer is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby. The Company further acknowledges that the Buyer is not
acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby, and any advice given by the Buyer or any of its representatives or
agents in connection with the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to the Buyer’s purchase of the Securities. The Company acknowledges and agrees that the Buyer has not made any
representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 2. 
 (n) Dilutive Effect. The Company understands and acknowledges that the number of Conversion Shares issuable upon conversion of the Notes will increase in certain circumstances. The Company further acknowledges that its obligation to
issue Conversion Shares upon conversion of the Notes in accordance with this Agreement, the Indenture and the 

 Notes is, in each case, absolute and unconditional regardless of the dilutive effect that such issuance may have on the
ownership interests of other shareholders of the Company. 
 (o) Internal Accounting Controls and Disclosure Controls. Except as
disclosed in Section 3(o) of the Disclosure Schedule, the Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general
or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset and liability accountability, (iii) access to assets or incurrence of
liabilities is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals

disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the Commission, including, without limitation,
controls and procedures designed in to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its
principal executive officer or officers and its principal financial officer or officers, as appropriate, to allow timely decisions regarding required disclosure. During the twelve months prior to the date hereof the Company has not received any
notice or correspondence from any accountant relating to any potential material weakness in any part of the system of internal accounting controls of the Company. 
 (p) Sarbanes-Oxley Act. The Company is in compliance with any and all applicable requirements of the Sarbanes-Oxley Act of 2002 that are effective as of the date hereof, and any and all applicable rules and
regulations promulgated by the Commission thereunder that are effective as of the date hereof. 
 (q) Rule 144A. The Notes satisfy the
requirements set forth in Rule l44A(d)(3) under the Securities Act. 
 (r) Trust Indenture Act. Assuming the accuracy of the
representations of the Buyer contained in Section 2 hereof and its compliance with the agreements set forth therein, it is not necessary in connection with the offer, sale and delivery of the Securities in the manner contemplated by this

 (s) Foreign
Corrupt Practices. Neither the Company, nor any director, officer, agent, employee or other Person acting on behalf of the Company has, in the course of its actions for, or on behalf of, the Company (i) used any corporate funds for any

knowledge of the Company, threatened. 
 (u) OFAC. Neither the Company nor, to the knowledge of the Company, any director, officer,
agent, employee or affiliate of the Company is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company will not, directly or indirectly, use the

payments to or from any such officer, director or employee or, to the knowledge of the Company, any corporation, partnership, trust or other entity in which any such officer, director, or employee has a substantial interest or is an officer,
director, trustee or partner. 
 (w) Indebtedness and Other Contracts. Except as disclosed in Disclosure Schedule
Section 3(w), the Company (i) does not have any outstanding Indebtedness (as defined below), (ii) is not a party to any contract, agreement or instrument, the violation of which, or default under which, by the other party(ies) to
such contract, agreement or instrument would result in a Material Adverse Effect, (iii) is not in violation of any term of or in default under any contract, agreement or instrument relating to any Indebtedness, except where such violations and
defaults would not result, individually or in the aggregate, in a Material Adverse Effect, or (iv) is not a party to any contract, agreement or instrument relating to any Indebtedness, the performance of which, in the judgment of the
Company’s officers, has or is expected to have a Material Adverse Effect. Disclosure Schedule Section 3(w) provides a detailed description of the material terms of any such outstanding Indebtedness. For purposes of this Agreement:
(x) “Indebtedness” of any Person means, without duplication (A) all indebtedness for borrowed money, (B) all obligations issued, undertaken or assumed as the deferred purchase price of property or services (including,
without limitation, “capital leases” in accordance with generally accepted accounting principles) (other than trade payables entered into in the ordinary course of business), (C) all reimbursement or payment obligations with respect
to letters of credit, surety 

 bonds and other similar instruments, (D) all obligations evidenced by notes, bonds, debentures or similar
instruments, including obligations so evidenced incurred in connection with the acquisition of property, assets or businesses, (E) all indebtedness created or arising under any conditional sale or other title retention agreement, or incurred as
financing, in either case with respect to any property or assets acquired with the proceeds of such indebtedness (even though the rights and remedies of the seller or bank under such agreement in the event of default are limited to repossession or
sale of such property), (F) all monetary obligations under any leasing or similar arrangement which, in connection with generally accepted accounting principles, consistently applied for the periods covered thereby, is classified as a capital
lease, (G) all indebtedness referred to in clauses (A) through (F) above secured by (or for which the holder of such Indebtedness has an existing right, contingent or otherwise, to be secured by) any mortgage, lien, pledge, charge,
security interest or other encumbrance upon or in any property or assets (including accounts and contract rights) owned by any Person, even though the Person which owns such assets or property has not assumed or become liable for the payment of such
indebtedness, and (H) all Contingent Obligations in respect of indebtedness or obligations of others of the kinds referred to in clauses (A) through (G) above; and (y) “Contingent Obligation” means, as to any Person,
any direct or indirect liability, contingent or otherwise, of that Person with respect to any indebtedness, lease, dividend or other obligation of another Person if the primary purpose or intent of the Person incurring such liability, or the primary
effect thereof, is to provide assurance to the obligee of such liability that such liability will be paid or discharged, or that any agreements relating thereto will be complied with, or that the holders of such liability will be protected (in whole
or in part) against loss with respect thereto. 
 (x) Insurance. The Company is insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company is engaged. The Company has not been refused any insurance coverage sought or
applied for and the Company has no reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business
at a cost that would not have a Material Adverse Effect. 
 (y) Employee Relations. (i) The Company is not a party to any
collective bargaining agreement or employs any member of a union. The Company believes that its relations with its employees are good. No executive officer of the Company (as defined in Rule 501(f) of the Securities Act) has notified the Company
that such officer intends to leave the Company or otherwise terminate such officer’s employment with the Company. No executive officer of the Company is, or is now expected to be, in violation of any material term of any employment contract,
confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer does not subject the Company to
any liability with respect to any of the foregoing matters. 
 (ii) The Company is in compliance with all federal, state, local and foreign
laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably
be expected to result in a Material Adverse Effect. 

 (z) Title. The Company has good and marketable title in fee simple to all real property owned by
it and good and marketable title to all personal property owned by it which is material to the business of the Company, in each case free and clear of all liens, encumbrances and defects except such as do not materially affect the value of such
property and do not interfere with the use made and proposed to be made of such property by the Company. Any real property and facilities held under lease by the Company are held by them under valid and enforceable leases with such exceptions as are
not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company. 
 (aa)
Environmental Laws. The Company (i) is in compliance with any and all Environmental Laws (as hereinafter defined), (ii) has received all permits, licenses or other approvals required of it under applicable Environmental Laws to
conduct its business and (iii) is in compliance with all terms and conditions of any such permit, license or approval where, in each of the foregoing clauses (i), (ii) and (iii), the failure to so comply could be reasonably expected to
have, individually or in the aggregate, a Material Adverse Effect. The term “Environmental Laws” means all federal, state, local or foreign laws relating to pollution or protection of human health or the environment (including, without
limitation, ambient air, surface water, groundwater, land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or
hazardous substances or wastes (collectively, “Hazardous Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials,
as well as all authorizations, codes, decrees, demands or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or approved thereunder. 
 (bb) Tax Status. The Company (i) has made or filed all foreign, federal and state income and all other tax returns, reports and declarations
required by any jurisdiction to which it is subject, (ii) has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due on such returns, reports and declarations, except those being
contested in good faith and (iii) has set aside on its books provision reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports or declarations apply. There are no unpaid taxes in any
material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim. 
 (cc) Ranking of Notes. Except for the Senior Debt (as such term is defined in the Indenture) and except as set forth on Schedule (cc), no Indebtedness of the Company is senior to or ranks pari passu with the Notes in
right of payment, whether with respect of payment of redemptions, interest, damages or upon liquidation or dissolution or otherwise. 
 (dd)
Off Balance Sheet Arrangements. There is no transaction, arrangement, or other relationship between the Company and an unconsolidated or other off balance sheet entity that is required to be disclosed by the Company in its filings under the
Exchange Act, and is not so disclosed, and that otherwise would be reasonably likely to have a Material Adverse Effect. 

 (ee) U.S. Real Property Holding Corporation. The Company is not, nor has ever been, a U.S. real
property holding corporation within the meaning of Section 897 of the Internal Revenue Code of 1986, as amended. 
 (ff) Investment
Company. The Company is not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof, will not become an “investment company” or an “affiliated person” of, or
“promoter” or “principal underwriter” for an investment company, within the meaning of the Investment Company Act of 1940, as amended. 
 (gg) Manipulation of Price. The Company has not, and to its knowledge no one acting on its behalf has, (i) taken, directly or indirectly, any action designed to cause or to result in the stabilization or
manipulation of the price of any security of the Company to facilitate the sale or resale of any of the Securities, (ii) other than payments due to Piper Jaffray upon the Closing, sold, bid for, purchased, or paid any compensation for
soliciting purchases of, any of the Securities, or (iii) other than payments due to Piper Jaffray upon the Closing, paid or agreed to pay to any person any compensation for soliciting another to purchase any other securities of the Company.

 (hh) Acknowledgement Regarding Buyer’s Trading Activity. Except as set forth in Section 2(f) and Section 2(l), it is
understood and acknowledged by the Company (i) that the Buyer has not been asked to agree, and the Buyer has not agreed, to desist from purchasing or selling, long and/or short, securities of the Company, or “derivative” securities
based on securities issued by the Company or to hold the Securities for any specified term; (ii) that the Buyer, and counter parties in “derivative” transactions to which the Buyer is a party, directly or indirectly, presently may
have a “short” position in the Common Stock, and (iii) that the Buyer shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction. Except as set forth
in Section 2(l), the Company further understands and acknowledges that (a) the Buyer may engage in hedging and/or trading activities at various times during the period that the Securities are outstanding, including, without limitation,
during the periods that the value of the Conversion Shares deliverable with respect to Securities are being determined and (b) such hedging and/or trading activities, if any, can reduce the value of the existing stockholders’ equity
interest in the Company both at and after the time the hedging and/or trading activities are being conducted. The Company acknowledges that such aforementioned hedging and/or trading activities do not constitute a breach of this Agreement, the
Indenture or any of the documents executed in connection herewith. 
 SECTION 4. Covenants. 
 (a) Obligations. Each party shall use commercially reasonable efforts to timely satisfy each of the conditions to be satisfied by it as provided in
Sections 5 and 6 of this Agreement. 
 (b) Form D and Blue Sky. The Company agrees to file timely a Form D with the Commission with
respect to the Securities as required under Regulation D and to promptly provide a copy thereof to the Buyer. The Company shall, on or before the Closing Date, take such action as the Company shall reasonably determine is necessary in order to
obtain an 

 
exemption for, or to qualify the Securities for, sale to the Buyer at the Closing pursuant to this Agreement under applicable securities or “Blue
Sky” laws of the states of the United States (or to obtain an exemption from such qualification), and shall provide evidence of any such action so taken to the Buyer on or prior to the Closing Date. The Company shall make all timely filings and
reports relating to the offer and sale of the Securities required under applicable securities or “Blue Sky” laws of the states of the United States following the Closing Date. The Company shall pay all fees and expenses in connection with
satisfying its obligations under this Section 4(b). 
 (c) Use of Proceeds. The Company intends to use the net proceeds from the
sale of the Notes to fund working capital requirements and for general corporate purposes. The Company may also use a portion of the net proceeds to in-license product candidates or to invest in or acquire businesses or technologies that it believes
are complementary to is own. 
 (d) Reservation of Shares. The Company shall take all actions necessary to at all times have
authorized, and reserved for the purpose of issuance, no less than one hundred percent (100%) of the sum of (i) the number of shares of Common Stock (the “Reservation Amount”) needed to provide for the issuance of the Conversion
Shares upon conversion of all of the Notes and (ii) the maximum number of shares of Common Stock issuable as Additional Shares (as defined in the Indenture) pursuant to the terms of the Indenture without regard to any limitations on
conversions. 
 (e) Listing. The Company shall promptly use its reasonable best efforts to promptly secure the listing of all of the
Conversion Shares upon the Principal Market or such other national securities exchange or automated quotation system, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance) and, shall maintain, so long as
any other shares of Common Stock shall be so listed, such listing of all Conversion Shares from time to time issuable under the terms of the Transaction Documents. So long as any Securities are outstanding, the Company shall use reasonable
commercial efforts to maintain the Common Stock’s authorization for quotation or listing on the Principal Market. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 4(e).

 (f) Filing of Form 8-K. By 8:30 a.m. (New York time) on the first Business Day following the execution of this Agreement, the
Company shall (i) issue press releases disclosing the transactions contemplated hereby, and, (ii) file with the Commission a Current Report on Form 8-K disclosing the material terms of this Agreement and the transactions contemplated
hereby (and attach as exhibits thereto this Agreement, the Registration Rights Agreement, the form of Note, the form of Indenture and the Subordination Agreement dated as of January 12, 2007, by and among the Trustee, the Company and Pfizer Inc.).
In addition, the Company will make such other filings and notices in the manner and time required by the Commission and the Principal Market. Notwithstanding the foregoing, the Company shall not publicly disclose the name of the Buyer (other than in
the Registration Statement and any filings with the Commission made in respect of this transaction in accordance with the Exchange Act) or any regulatory agency or trading market, without the prior written consent of Buyer, except to the extent such
disclosure is required by law or trading market regulations. “Business Day” 

 
means any day other than Saturday, Sunday or other day on which commercial banks in The City of New York are required by law to remain closed. 
 (g) Stockholder Approval. In the event that Stockholder Approval is required pursuant to the rules of the Principal Market because the number of
Conversion Shares and the maximum number of Additional Shares is greater in the aggregate than 19.99% of the number of shares of Common Stock outstanding immediately prior to the Closing Date (the “19.99% Rule”), the Company shall provide
each stockholder entitled to vote at the next meeting of stockholders of the Company (the “Stockholders Meeting”), which meeting shall occur on or before ninety (90) days from the date of such determination (the “Stockholders
Meeting Deadline”), a proxy statement, which has been previously reviewed by the Buyer and its counsel, soliciting each such stockholder’s affirmative vote at such stockholder meeting for approval of the Company’s issuance of all of
the Securities as described in the Transaction Documents in accordance with applicable law and the rules and regulations of the Principal Market (such affirmative approval being referred to herein as the “Stockholder Approval”), and the
Company shall solicit its stockholders’ approval of such issuance of the Securities. If, despite the Company’s reasonable best efforts the Stockholder Approval is not obtained on or prior to the Stockholder Meeting Deadline, the Company
shall cause an additional Stockholder Meeting to be held each six month period thereafter until such Stockholder Approval is obtained, provided that if the Company’s Board of Directors does not recommend to the stockholders that they approve
the Resolutions at any such Stockholder Meeting and the Stockholder Approval is not obtained the Company shall cause an additional Stockholder Meeting to be held each calendar quarter thereafter until such Stockholder Approval is obtained.

 (h) Expenses. (i) The Company shall be responsible for the payment of any placement agent’s fees or
commissions, financial advisory fees, or broker’s commissions (other than for Persons engaged by the Buyer) relating to or arising out of the transactions contemplated hereby, including, without limitation, any fees or commissions payable to
Piper Jaffray. The Company shall pay, and hold the Buyer harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and out-of-pocket expenses) arising in connection with any claim relating to
any such payment. 
 (ii) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is
terminated, the Company shall pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, all fees, costs and expenses (A) incident to the preparation, issuance,
execution, authentication and delivery of the Securities, including any expenses of the Trustee, (ii) incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws
of such jurisdictions as the Buyer may reasonably designate, (iii) in connection with the admission for trading of the Notes on any securities exchange or inter-dealer quotation system (as well as in connection with the admission of the Notes
for trading in the PORTAL Market or any appropriate market system), (iv) related to any filing with the National Association of Securities Dealers, Inc. and (v) in connection with satisfying its obligations under Section 4(r).

 (i) Additional Securities; Variable Securities. For so long as the Buyer beneficially owns any
Securities, the Company will not issue any Notes other than to the Buyer as contemplated hereby and the Company shall not issue any other securities that would cause a breach or default under the Notes. The Company shall not issue, sell, offer for
sale or solicit offers to buy or otherwise negotiate in respect of any other securities in such a manner as would require the registration of the issuance of the Securities by the Company under purposes of any federal or state securities law or
require stockholder approval under the rules and regulations of the Principal Market. For so long as any Notes remain outstanding, the Company shall not, in any manner, issue or sell any rights, warrants or options to subscribe for or purchase
Common Stock or directly or indirectly convertible into or exchangeable or exercisable for Common Stock, having a conversion, exchange or exercise price which varies or may vary with the market price of the Common Stock, including by way of one or
more reset(s) to any fixed price, unless the conversion, exchange or exercise price of any such security cannot be less than the then applicable Conversion Price (as defined in the Notes). 
 (j) Tax Matters. For United States Federal income tax purposes, the Company and the Buyer agree (i) to treat the Notes as indebtedness and
(ii) to treat the Notes as having been issued for an aggregate purchase price of $22,500,000 and with an original issue discount which shall be amortized pursuant to the terms of the Indenture. If the Company shall be required to withhold or
deduct any tax or other governmental charge from any payment made hereunder or under any Note to the Buyer, then, subject to the last sentence of this Section 4(k), the Company shall pay to the Buyer such additional amounts as are necessary
such that the Buyer actually receives the amount the Buyer would have received if no such withholding or deduction had been required. If the Buyer is organized under the laws of a jurisdiction other than the United States, any State thereof or the
District of Columbia (a “Non-United States Buyer”), the Buyer shall deliver to the Company either (a) two (2) copies of either United States Internal Revenue Service Form W-8BEN or Form W-8ECI, or (b) if the Buyer claims
exemption from United States Federal withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder (the “Code”) with respect to payments of
“portfolio interest”, a certificate in form and substance reasonably acceptable to the Company representing that such Non-United States Buyer is not a bank for purposes of Section 881(c) of the Code, is not a ten percent
(10%) shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Company and is not a controlled foreign corporation related to the Company (within the meaning of Section 864(d)(4) of the Code), together with Internal
Revenue Service Form W-8, in all cases, such forms and other documents being properly completed and duly executed by the Buyer. If the Buyer is not otherwise exempt from “back-up withholding” it shall deliver to the Company properly
completed and duly executed Internal Revenue Service Form W-8 or W-9 indicating that the Buyer is subject to “back-up withholding” for United States Federal income tax purposes. The forms and other documents required to be delivered
pursuant to the two preceding sentences shall be delivered within ten (10) days after the Closing Date. The Company shall not be required to pay any additional amounts (x) to the Buyer, in respect of United States Federal withholding tax
or (y) to the Buyer, if a United States entity, in respect of United States Federal “back-up withholding” tax. 
 (k)
Violation of Laws. The business of the Company and its subsidiaries, if any, shall not be conducted in violation of any law, ordinance or regulation of any governmental 

 entity, except where such violations would not result, either individually or in the aggregate, in a Material Adverse
Effect. 
 (l) CUSIP Numbers. The Company in issuing the Securities shall use “CUSIP” numbers (if then generally in use),
and shall use such “CUSIP” numbers in notices to holders as a convenience to holders thereof; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities
or as contained in any notice to such holders and that reliance may be placed only on other identification numbers printed on such Securities, and any such Company action referenced in such notice (including, without limitation, redemption or
automatic conversion of Notes) shall not be affected by any defect in or omission of such numbers. 
 (m) Nonpublic Information. The
Company shall not, and shall cause its officers, directors, employees and agents, not to, provide the Buyer with any material, nonpublic information regarding the Company from and after the filing of the Current Report on Form 8-K with the
Commission pursuant to Section 4(f) hereof without the express written consent of the Buyer; provided, however that the foregoing shall not restrict in any way the distribution of any information to the Buyer by the Company and its officers,
directors, employees and agents (i) as reasonably required by the terms of the Transaction Documents or (ii) in connection with any request by or on behalf of the Company to waive, amend or modify any provision of the Transaction
Documents. In the event of a breach of the foregoing covenant by the Company, or any of its officers, directors, employees and agents, in addition to any other remedy provided herein or in the Transaction Documents, the Buyer shall have the right to
make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material, nonpublic information without the prior approval by the Company, or any of its officers, directors, employees or agents. The Buyer shall
have no liability to the Company, or any of its officers, directors, employees, stockholders or agents for any such disclosure. In addition, the Company will make such other filings and notices in the manner and time required by the Commission and
the Principal Market. 
 (n) [INTENTIONALLY OMITTED] 
 (o) Outstanding Common Stock. The Company shall, within two Business Days of receipt of a written request from the Buyer, inform the Buyer of the number of shares of Common Stock outstanding as of the most
recent practicable date. 
 (p) Qualification Under Trust Indenture Act. Prior to any registration of the Notes or the Conversion
Shares pursuant to the Registration Rights Agreement, or at such earlier time as may be so required, the Company shall qualify the Indenture under Trust Indenture Act and to enter into any necessary supplemental indentures in connection therewith.

 (q) Transfer Agent Instructions. The Company shall issue instructions to its transfer agent, and any subsequent transfer agent, to
issue certificates or credit shares to the applicable balance accounts at DTC, registered in the name of the Buyer or its nominee(s), for the Conversion Shares and the Additional Shares in such amounts as specified from time to time by the Buyer to
the Company upon conversion of the Notes and prior to issuance of the Additional Shares and in accordance with their respective terms (the “Transfer Agent 

 Instructions”), substantially in the form attached hereto as Exhibit C. Prior to transfer or sale pursuant to
a registration statement or Rule 144 under the Securities Act of the Conversion Shares, all such certificates shall bear the restrictive legend specified in Section 2.5(h)(ii) of the Indenture. The Company represents and warrants that no
instruction inconsistent with the Transfer Agent Instructions referred to in this Section 4(q) will be given by the Company to its transfer agent and that the Securities shall be freely transferable on the books and records of the Company as
and to the extent provided in this Agreement, the Notes, the Indenture and the Registration Rights Agreement, and subject to the Securities Act. Subject to the Indenture, if the Buyer provides the Company with an opinion of counsel, in form and from
counsel reasonably acceptable to the Company, to the effect that a sale, assignment or transfer of the Securities can be made without registration under the Securities Act or that the Securities can be sold pursuant to Rule 144(k) without any
restriction as to the number of securities acquired as of a particular date that can then be immediately sold, and provides such representations that the Company shall reasonably request confirming compliance with the requirements of Rule 144, the
Company shall permit the transfer, and, in the case of the Conversion Shares, promptly instruct its transfer agent to issue one or more certificates, or credit shares to one or more balance accounts at DTC, in such name and in such denominations as
specified by the Buyer and without any restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Buyer by vitiating the intent and purpose of the transaction contemplated hereby.
Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 4(q) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this
Section 4(q), that the Buyer shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and
without any bond or other security being required. As soon as practicable, but in no event later than five (5) Business Days after the Closing Date, the Company shall deliver the Transfer Agent Instructions, in the form of Exhibit C
attached hereto, to the Company’s transfer agent. 
 (r) Financial Information. For so long as any Securities remain outstanding
and are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Company will, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, make available to the Buyer
and any holder of Securities in connection with any sale thereof and any prospective purchaser of Securities and securities analysts, in each case upon request, the information specified in, and meeting the requirements of, Rule 144A(d)(4) under the
Securities Act (or any successor thereto). 
 (s) Pledge of Securities. The Company acknowledges and agrees that the Securities may be
pledged by any holder of the Securities in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities. The pledge of Securities shall not be deemed to be a transfer, sale or assignment of
the Securities hereunder, and no holder effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document. The
Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request, at the Buyer’s expense, in connection with a pledge of the Securities to such pledgee by such holder. 

 (t) Prohibition on Certain Additional Issuances of Securities. 
 (i) For purposes of this Section 4(t), the following definitions shall apply. 
 (1) “Convertible Securities” means any stock or securities (other than Options) convertible into or exercisable or exchangeable
for shares of Common Stock. 
 (2) “Options” means any rights, warrants or options to subscribe for or purchase
shares of Common Stock or Convertible Securities. 
 (3) “Common Stock Equivalents” means, collectively, Options and
Convertible Securities. 
 (ii) From the date hereof until the ninetieth (90th) day after the Closing Date (the
“Trigger Date”), the Company hereby agrees that, it will not, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase,
lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any Common Stock Equivalents, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of the Common Stock (any actions set forth in clause (i) or (ii) hereof, being referred to as a “Subsequent Placement”), and (iii) file with the Commission a registration statement under the
Securities Act relating to any additional shares of its Common Stock or Common Stock Equivalents, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in
cash or otherwise. 
 (iii) The restrictions contained in clause (ii) above shall not apply in connection with the
issuance or registration of any shares of Common Stock issued or issuable pursuant to employee benefit plans, qualified stock option plans or other employee compensation or incentive plans or pursuant to options, warrants or rights outstanding on
the date hereof (provided that the terms of such options or warrants are not amended or modified in any manner after the date hereof and prior to the Trigger Date). 
 (u) Blue Sky. The Company shall endeavor to qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Buyer shall reasonably request and to continue such
qualification in effect so long as reasonably required for re-sale of the Securities and to pay all related fees and expenses reasonably incurred in connection with such qualification and in connection with the determination of the eligibility of
the Securities for investment under the laws of such jurisdictions as the Buyer may designate; provided that the Company shall not be required to file a general consent to service of process in any jurisdiction or to qualify as a foreign corporation
in any jurisdiction in which it is not so qualified or to subject itself to taxation in any such jurisdiction if it is not otherwise so subject. 

 (v) Regulation M. The Company will not take any action prohibited by Regulation M under the
Exchange Act, in connection with the offer, sale and delivery of the Securities contemplated hereby. 
 (w) General Solicitation. None
of the Company, any of its affiliates (as defined in Rule 501(b) under the Securities Act) or any person acting on behalf of the Company or such affiliate will solicit any offer to buy or offer or sell the Securities by means of any form of general
solicitation or general advertising within the meaning of Regulation D, including: (i) any advertisement, article, notice or other communication published in any newspaper, magazine or similar medium or broadcast over television or radio;
and (ii) any seminar or meeting whose attendees have been invited by any general solicitation or general advertising. 
 SECTION 5.
Conditions to the Company’s Obligation to Close. The obligation of the Company to issue and sell the Notes to the Buyer at the Closing is subject to the satisfaction, at or before the Closing Date, of each of the following conditions,

to waive such unsatisfied condition(s)), the nonbreaching party shall have the option to terminate this Agreement with respect to such breaching party at the
close of business on such date without liability of any party to any other party; provided, however, this if this Agreement is terminated pursuant to this Section 7, the Company shall remain obligated to reimburse the Buyer for the
expenses described in Section 4(h) above. 
 SECTION 8. Indemnification. 
 (a) Indemnification of the Buyer. In consideration of the Buyer’s execution and delivery of the Transaction Documents and acquiring the
Securities thereunder and Piper Jaffray’s agreement to act as exclusive placement agent and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold
harmless Piper Jaffray and the Buyer and their respective directors, officers, shareholders, members, affiliates, partners, employees and agents (each, an “Indemnitee”) from any and all losses, liabilities, obligations, claims,
contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation (collectively, “Claims”) that any such Indemnitee may suffer or
incur as a result of or relating to (i) any misrepresentation, breach or inaccuracy of any representation, warranty, covenant or agreement made by the Company in this Agreement or (ii) any cause of action, suit or claim brought or made
against such Indemnitee by a third party (including for these purposes a derivative action) brought on behalf of the Company and arising out of or resulting from (1) the Company’s execution, delivery or performance of the Transaction
Documents or any other certificate, instrument or document contemplated hereby or thereby, (2) any transaction financed or to be financed by the Company in whole or in part, directly or indirectly, with the proceeds of the issuance of the
Securities or (3) any disclosure made by the Buyer pursuant to Section 4(f). In addition to the indemnity contained herein, the Company will reimburse each Indemnitee for its reasonable legal and other expenses (including the cost of any
investigation, preparation and travel in connection therewith) incurred in connection therewith, as such expenses are incurred. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make
the maximum contribution to the payment and satisfaction of each of the Claims which is permissible under applicable law. 
 (b)
Procedures for Indemnification. Promptly after an Indemnitee has knowledge of any Claim as to which such Indemnitee reasonably believes indemnity may be sought or promptly after such Indemnitee receives notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnitee shall, if a Claim in respect thereof is to be made against the Company under this Section 8, deliver to the Company a written notice of
such Claim, and the Company shall have the right to participate in, and, to the extent the Company so desires, to assume control of the defense thereof with counsel mutually satisfactory to the Company and the Indemnitee; provided, however, that an
Indemnitee shall have the right to retain its own counsel if, in the reasonable opinion of counsel retained by the Company, the representation by such counsel of the Indemnitee and the Company would be inappropriate due to actual or potential
differing interests between such Indemnitee and the Company; provided, further, that the Company shall not be responsible for the reasonable fees and expense of more than one (1) separate legal counsel for such Indemnitee. The Indemnitee shall
cooperate fully with the Company in connection with any negotiation or defense of any such action or Claim by the Company and 

 
shall furnish to the Company all information reasonably available to the Indemnitee which relates to such action or Claim. The Company shall keep the
Indemnitee fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. The Company shall not be liable for any settlement of any Claim effected without its prior written consent; provided,
however, that the Company shall not unreasonably withhold, delay or condition its consent. The Company shall not, without the prior written consent of the Indemnitee, consent to entry of any judgment or enter into any settlement or other compromise
which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee of a full release from all liability in respect to such Claim, action and proceeding. The failure to deliver written notice to the
Company as provided in this Agreement shall not relieve the Company of any liability to the Indemnitee under this Section 8, except to the extent that the Company is materially prejudiced in its ability to defend such action. 
 (c) The indemnification required by this Section 8 shall be made by periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Claims are incurred. 
 (d) The indemnity agreements contained herein shall be in addition to
(i) any cause of action or similar right of the Indemnitee against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law. 
 SECTION 9. Miscellaneous. 
 (a)

inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy
thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way

permitted subsequent holders of the Securities and shall inure to the benefit of those persons and, to the extent provided in Section 9(i), Piper Jaffray. The Company shall not assign this Agreement or any rights or obligations hereunder
without the prior written consent of the Buyer, including by merger or consolidation, except pursuant to a merger or consolidation permitted under Article XII of the Indenture or pursuant to a Change of Control (as defined in the Indenture) with

without limitation, attorney’s fees and out-of-pocket expenses) arising in connection with any such claim.

all other rights granted by law.

hereunder or pursuant to any of the other Transaction Documents, or the Buyer enforces or exercises its rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without
limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full
force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

in accordance with the terms of the Indenture.
