Loan and Security Agreement of even date herewith among
Silicon Valley Bank, Oxford Finance LLC and the Company
(the “Loan Agreement”)

THIS WARRANT CERTIFIES THAT, for good and valuable consideration, including without limitation
the mutual promises contained in the Loan Agreement OXFORD FINANCE LLC (together with any
registered holder from time to time of this Warrant or any holder of the shares issuable or issued
upon exercise of this Warrant, “Holder”) is entitled to purchase the number of fully paid and
non-assessable shares (the “Shares”) of the above-stated Class of Stock (the “Class”) of the
above-named company (the “Company”) at the above-stated Warrant Price, all as set forth above and
as adjusted pursuant to Article 2 of this Warrant, subject to the provisions and upon the terms and
conditions set forth in this Warrant.

ARTICLE 1. EXERCISE.

1.1 Method of Exercise. Holder may exercise this Warrant by delivering the original
of this Warrant together with a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company. Unless Holder is exercising the conversion
right set forth in Article 1.2, Holder shall also deliver to the Company a certified or bank check,
wire transfer of same-day funds (to an account designated by the Company), or other form of payment
acceptable to the Company for the aggregate Warrant Price for the Shares being purchased.

1.2 Conversion Right. In lieu of exercising this Warrant as specified in Article 1.1,
Holder may from time to time convert this Warrant, in whole or in part, into a number of Shares
determined by dividing (a) the aggregate fair market value of the Shares or other securities
otherwise issuable upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share. The fair market value of the Shares shall be determined
pursuant to Article 1.3.

 

 

 

1.3 Fair Market Value. If the Class is traded in a public market, the fair market
value of a Share shall be the average closing prices of a share of common stock reported for the
three (3) business days immediately before Holder delivers this Warrant together with its Notice of
Exercise to the Company. If the Class is not traded in a public market, the Board of Directors of
the Company shall determine fair market value in its reasonable good faith judgment.

1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises or
converts this Warrant and, if applicable, the Company receives payment of the aggregate Warrant
Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this
Warrant has not been fully exercised or converted and has not expired, a new Warrant representing
the Shares not so acquired.

1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss,
theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and
amount to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

1.6 Treatment of Warrant Upon Acquisition of Company.

1.6.1 “Acquisition”. For the purpose of this Warrant, “Acquisition” means any sale,
exclusive license, or other disposition of all or substantially all of the assets of the Company,
or any reorganization, consolidation, merger or sale of outstanding capital stock of the Company
where the holders of the Company’s outstanding voting securities before the transaction
beneficially own less than a majority of the outstanding voting securities of the surviving entity
or, if applicable, its parent entity, after the transaction.

1.6.2 Treatment of Warrant at Acquisition.

A) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that
is not a True Asset Sale (as defined below) in which the sole consideration is cash, either (a)
Holder shall exercise its conversion or purchase right under this Warrant and such exercise will be
deemed effective immediately prior to and contingent upon the consummation of such Acquisition or
(b) if Holder elects not to exercise the Warrant, this Warrant will expire upon the consummation of
such Acquisition. The Company shall provide the Holder with written notice of its request relating
to the foregoing (together with such reasonable information as the Holder may request in connection
with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder
not less than ten (10) days prior to the closing of the proposed Acquisition.

B) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that
is an “arms length” sale of all or substantially all of the Company’s assets (and only its assets)
to a third party that is not an Affiliate (as defined below) of the Company (a “True Asset Sale”),
either (a) Holder shall exercise its conversion or purchase right under this Warrant and such
exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b)
if Holder elects not to exercise the Warrant, this Warrant will continue until the Expiration Date
if the Company continues as a going concern following the closing of any such True Asset Sale. The
Company shall provide the Holder with written notice of its request relating to the foregoing
(together with such reasonable information as the Holder may request
in connection with such contemplated Acquisition giving rise to such notice), which is to be
delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition.

 

2

 

C) Upon the closing of any Acquisition other than those particularly described in subsections (A)
and (B) above, the successor entity shall assume the obligations of this Warrant, and this Warrant
shall be exercisable for the same securities, cash, and property as would be payable for the Shares
issuable upon exercise of the unexercised portion of this Warrant as if such Shares were
outstanding on the record date for the Acquisition and subsequent closing. The Warrant Price
and/or number of Shares shall be adjusted accordingly.

D) Notwithstanding the foregoing provisions of this Section 1.6.2., in the event that the acquiror
in an Acquisition does not agree to assume this Warrant at and as of the closing thereof, this
Warrant, to the extent not exercised or converted on or prior to such closing, shall terminate and
be of no further force or effect as of immediately following such closing if all of the following
conditions are met: (i) the acquiror is subject to the reporting requirements of Section 13 or
Section 15(d) of the Securities Exchange Act of 1934, as amended, (ii) the class of stock or other
security of the acquiror that would be received by Holder in connection with such Acquisition were
Holder to exercise or convert this Warrant on or prior to the closing thereof is listed for trading
on a national securities exchange or approved for quotation on an automated inter-dealer quotation
system, and (iii) the value (determined as of the closing of such Acquisition in accordance with
the definitive agreements therefor) of the acquiror stock and/or other securities that would be
received by Holder in respect of each Share were Holder to exercise or convert this Warrant on or
prior to the closing of such Acquisition is equal to or greater than three (3) times the
then-effective Warrant Price.

As used in this Section 1.6, “Affiliate” shall mean any person or entity that owns or
controls directly or indirectly ten percent (10%) or more of the stock of Company, any person or
entity that controls or is controlled by or is under common control with such persons or entities,
and each of such person’s or entity’s officers, directors, joint venturers or partners, as
applicable.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the
outstanding shares of the Class payable in common stock or other securities, then upon exercise of
this Warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total
number and kind of securities to which Holder would have been entitled had Holder owned the Shares
of record as of the date the dividend occurred. If the Company subdivides the outstanding shares
of the Class by reclassification or otherwise into a greater number of shares, the number of Shares
purchasable hereunder shall be proportionately increased and the Warrant Price shall be
proportionately decreased. If the outstanding shares of the Class are combined or consolidated, by
reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be
proportionately increased and the number of Shares shall be proportionately decreased.

2.2 Reclassification, Exchange, Combinations or Substitution. Upon any
reclassification, exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall
be entitled to receive, upon exercise or conversion of this Warrant, the number and kind of
securities and property that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or other event, and the
Warrant Price shall be adjusted proportionately. The Company or its successor shall
promptly issue to Holder an amendment to this Warrant setting forth the number and kind of
such new securities or other property issuable upon exercise or conversion of this Warrant as a
result of such reclassification, exchange, substitution or other event that results in a change of
the number and/or class of securities issuable upon exercise or conversion of this Warrant. The
amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may
be practicable to the adjustments provided for in this Article 2 including, without limitation,
adjustments to the Warrant Price and to the number of securities or property issuable upon exercise
of the new Warrant. The provisions of this Article 2.2 shall similarly apply to successive
reclassifications, exchanges, substitutions, or other events.

 

3

 

2.3 [Intentionally Omitted].

2.4 No Impairment. The Company shall not, by amendment of its Certificate of
Incorporation or through a reorganization, transfer of assets, consolidation, merger, dissolution,
issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed under this Warrant by the Company,
but shall at all times in good faith assist in carrying out of all the provisions of this Article 2
and in taking all such action as may be necessary or appropriate to protect Holder’s rights under
this Article against impairment; provided, however, that notwithstanding the foregoing, nothing in
this Section 2.4 shall restrict or impair the Company’s right to effect changes to the rights,
preferences, and privileges associated with the Shares with the requisite consent of the
stockholders as may be required to amend the Certificate of Incorporation from time to time so long
as such amendment affects the rights, preferences, and privileges granted to Holder associated with
the Shares in the same manner as the other holders of outstanding shares of the Class.

2.5 Fractional Shares. No fractional Shares shall be issuable upon exercise or
conversion of the Warrant and the number of Shares to be issued shall be rounded down to the
nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the
Warrant, the Company shall eliminate such fractional share interest by paying Holder the amount
computed by multiplying the fractional interest by the fair market value of a full Share.

2.6 Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Class
and/or number of Shares, the Company shall promptly notify Holder in writing, and, at the Company’s
expense, promptly compute such adjustment, and furnish Holder with a certificate of its Chief
Financial Officer setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant
Price, Class and number of Shares in effect upon the date thereof and the series of adjustments
leading to such Warrant Price, Class and number of Shares.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

3.1 Representations and Warranties. The Company represents and warrants to, and
agrees with, the Holder as follows:

(a) All Shares which may be issued upon the exercise of the purchase right represented by this
Warrant shall, upon issuance, be duly authorized, validly issued, fully paid and non-assessable,
and free of any liens and encumbrances except for restrictions on transfer provided for herein or
under applicable federal and state securities laws.

 

4

 

3.2 Notice of Certain Events. If the Company proposes at any time (a) to declare any
dividend or distribution upon the outstanding shares of the same class and series as the Shares,
whether in cash, property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for subscription or sale pro rata to the holders of the outstanding shares of the same
class and series as the Shares any additional shares of any class or series of the Company’s stock;
(c) to effect any reclassification, reorganization or recapitalization of the outstanding shares of
the Class; or (d) to effect an Acquisition or to liquidate, dissolve or wind up, then, in
connection with each such event, the Company shall give Holder notice thereof at the same time and
in the same manner as the Company notifies the holders of the outstanding shares of the Class
thereof. Company will also provide information requested by Holder reasonably necessary to enable
the Holder to comply with the Holder’s accounting or reporting requirements, subject to Holder
being bound by customary confidentiality obligations.

3.3 No Shareholder Rights. Except as provided in this Warrant, Holder will not have
any rights as a shareholder of the Company until the exercise of this Warrant.

ARTICLE 4. REPRESENTATIONS, WARRANTIES OF THE HOLDER.

The Holder represents and warrants to the Company as follows:

4.1 Purchase for Own Account. This Warrant and the securities to be acquired upon
exercise of this Warrant by Holder will be acquired for investment for Holder’s account, not as a
nominee or agent, and not with a view to the public resale or distribution within the meaning of
the Act. Holder also represents that it has not been formed for the specific purpose of acquiring
this Warrant or the Shares.

4.2 Disclosure of Information. Holder has received or has had full access to all the
information it considers necessary or appropriate to make an informed investment decision with
respect to the acquisition of this Warrant and its underlying securities. Holder further has had
an opportunity to ask questions and receive answers from the Company regarding the terms and
conditions of the offering of this Warrant and its underlying securities and to obtain additional
information (to the extent the Company possessed such information or could acquire it without
unreasonable effort or expense) necessary to verify any information furnished to Holder or to which
Holder has access.

4.3 Investment Experience. Holder understands that the purchase of this Warrant and
its underlying securities involves substantial risk. Holder has experience as an investor in
securities of companies in the development stage and acknowledges that Holder can bear the economic
risk of such Holder’s investment in this Warrant and its underlying securities and has such
knowledge and experience in financial or business matters that Holder is capable of evaluating the
merits and risks of its investment in this Warrant and its underlying securities and/or has a
preexisting personal or business relationship with the Company and certain of its officers,
directors or controlling persons of a nature and duration that enables Holder to be aware of the
character, business acumen and financial circumstances of such persons.

4.4 Accredited Investor Status. Holder is an “accredited investor” within the meaning
of Regulation D promulgated under the Act.

4.5 The Act. Holder understands that this Warrant and the Shares issuable upon
exercise or conversion hereof have not been registered under the Act in reliance upon a specific
exemption therefrom, which exemption depends upon, among other things, the bona
fide nature of the Holder’s investment intent as expressed herein. Holder understands that
this Warrant and the Shares issued upon any exercise or conversion hereof must be held indefinitely
unless subsequently registered under the Act and qualified under applicable state securities laws,
or unless exemption from such registration and qualification are otherwise available.

ARTICLE 5. MISCELLANEOUS.

5.1 Term: This Warrant is exercisable in whole or in part at any time and from time
to time on or before the Expiration Date.

5.2 Legends. This Warrant and the Shares (and the securities issuable, directly or
indirectly, upon conversion of the Shares, if any) shall be imprinted with a legend in
substantially the following form:

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE
SECURITIES LAWS OF ANY STATE AND, EXCEPT FOR AND PURSUANT TO THE
PROVISIONS OF ARTICLE 5 OF THAT CERTAIN WARRANT TO PURCHASE STOCK
ISSUED BY THE COMPANY TO OXFORD FINANCE LLC DATED AS OF AUGUST 2,
2011 MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR
HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND
APPLICABLE STATE SECURITIES LAWS OR, IN THE OPINION OF LEGAL COUNSEL
IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE
SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS
EXEMPT FROM REGISTRATION.

5.3 Compliance with Securities Laws on Transfer. This Warrant and the Shares issuable
upon exercise of this Warrant (and the securities issuable, directly or indirectly, upon conversion
of the Shares, if any) may not be transferred or assigned in whole or in part without compliance
with applicable federal and state securities laws by the transferor and the transferee (including,
without limitation, the delivery of investment representation letters and legal opinions reasonably
satisfactory to the Company, as reasonably requested by the Company). The Company shall not
require Holder to provide an opinion of counsel if the transfer is to any “affiliate” (as such term
is defined in Regulation D promulgated under the Act) of Holder, provided that any such transferee
is an “accredited investor” as defined in Regulation D promulgated under the Act. Additionally,
the Company shall also not require an opinion of counsel if there is no material question as to the
availability of an exemption to registration under Rule 144, including without limitation, the
availability of current information as referenced in Rule 144(c), Holder represents that it has
complied with Rule 144(d) and (e) in reasonable detail, the selling broker represents that it has
complied with Rule 144(f), and the Company is provided with a copy of Holder’s notice of proposed
sale.

5.4 Transfer Procedure. After receipt by Holder of the executed Warrant, Oxford may
transfer all or part of this Warrant to one or more of Oxford’s affiliates (each, an “Oxford
Affiliate”), by execution of an Assignment substantially in the form of Appendix 2. Subject to the
provisions of Article 5.3 and upon providing the Company with written notice,
Oxford, any such Oxford Affiliate and any subsequent Holder may transfer all or part of this
Warrant or the Shares issuable upon exercise of this Warrant (or the securities issuable directly
or indirectly, upon conversion of the Shares, if any) to any transferee, provided, however, in
connection with any such transfer, the Oxford Affiliate(s) or any subsequent Holder will give the
Company notice of the portion of the Warrant being transferred with the name, address and taxpayer
identification number of the transferee and Holder will surrender this Warrant to the Company for
reissuance to the transferee(s) (and Holder if applicable). The Company may refuse to transfer
this Warrant or the Shares to any person who directly competes with the Company (as determined by
Holder), unless, in either case, the stock of the Company is publicly traded. Any transferee shall
take this Warrant subject to all provisions and restrictions contained herein.

5.5 Notices. All notices and other communications from the Company to the Holder, or
vice versa, shall be deemed delivered and effective when given personally or mailed by first-class

of this Warrant together with a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company. Unless Holder is exercising the conversion
right set forth in Article 1.2, Holder shall also deliver to the Company a certified or bank check,
wire transfer of same-day funds (to an account designated by the Company), or other form of payment
acceptable to the Company for the aggregate Warrant Price for the Shares being purchased.

1.2 Conversion Right. In lieu of exercising this Warrant as specified in Article 1.1,
Holder may from time to time convert this Warrant, in whole or in part, into a number of Shares
determined by dividing (a) the aggregate fair market value of the Shares or other securities
otherwise issuable upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share. The fair market value of the Shares shall be determined
pursuant to Article 1.3.

 

 

 

1.3 Fair Market Value. If the Class is traded in a public market, the fair market
value of a Share shall be the average closing prices of a share of common stock reported for the
three (3) business days immediately before Holder delivers this Warrant together with its Notice of
Exercise to the Company. If the Class is not traded in a public market, the Board of Directors of
the Company shall determine fair market value in its reasonable good faith judgment.

1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises or
converts this Warrant and, if applicable, the Company receives payment of the aggregate Warrant
Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this
Warrant has not been fully exercised or converted and has not expired, a new Warrant representing
the Shares not so acquired.

1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss,
theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and
amount to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

1.6 Treatment of Warrant Upon Acquisition of Company.

1.6.1 “Acquisition”. For the purpose of this Warrant, “Acquisition” means any sale,
exclusive license, or other disposition of all or substantially all of the assets of the Company,
or any reorganization, consolidation, merger or sale of outstanding capital stock of the Company
where the holders of the Company’s outstanding voting securities before the transaction
beneficially own less than a majority of the outstanding voting securities of the surviving entity
or, if applicable, its parent entity, after the transaction.

1.6.2 Treatment of Warrant at Acquisition.

A) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that
is not a True Asset Sale (as defined below) in which the sole consideration is cash, either (a)
Holder shall exercise its conversion or purchase right under this Warrant and such exercise will be
deemed effective immediately prior to and contingent upon the consummation of such Acquisition or
(b) if Holder elects not to exercise the Warrant, this Warrant will expire upon the consummation of
such Acquisition. The Company shall provide the Holder with written notice of its request relating
to the foregoing (together with such reasonable information as the Holder may request in connection
with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder
not less than ten (10) days prior to the closing of the proposed Acquisition.

B) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that
is an “arms length” sale of all or substantially all of the Company’s assets (and only its assets)
to a third party that is not an Affiliate (as defined below) of the Company (a “True Asset Sale”),
either (a) Holder shall exercise its conversion or purchase right under this Warrant and such
exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b)
if Holder elects not to exercise the Warrant, this Warrant will continue until the Expiration Date
if the Company continues as a going concern following the closing of any such True Asset Sale. The
Company shall provide the Holder with written notice of its request relating to the foregoing
(together with such reasonable information as the Holder may request
in connection with such contemplated Acquisition giving rise to such notice), which is to be
delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition.

 

2

 

C) Upon the closing of any Acquisition other than those particularly described in subsections (A)
and (B) above, the successor entity shall assume the obligations of this Warrant, and this Warrant
shall be exercisable for the same securities, cash, and property as would be payable for the Shares
issuable upon exercise of the unexercised portion of this Warrant as if such Shares were
outstanding on the record date for the Acquisition and subsequent closing. The Warrant Price
and/or number of Shares shall be adjusted accordingly.

D) Notwithstanding the foregoing provisions of this Section 1.6.2., in the event that the acquiror
in an Acquisition does not agree to assume this Warrant at and as of the closing thereof, this
Warrant, to the extent not exercised or converted on or prior to such closing, shall terminate and
be of no further force or effect as of immediately following such closing if all of the following
conditions are met: (i) the acquiror is subject to the reporting requirements of Section 13 or
Section 15(d) of the Securities Exchange Act of 1934, as amended, (ii) the class of stock or other
security of the acquiror that would be received by Holder in connection with such Acquisition were
Holder to exercise or convert this Warrant on or prior to the closing thereof is listed for trading
on a national securities exchange or approved for quotation on an automated inter-dealer quotation
system, and (iii) the value (determined as of the closing of such Acquisition in accordance with
the definitive agreements therefor) of the acquiror stock and/or other securities that would be
received by Holder in respect of each Share were Holder to exercise or convert this Warrant on or
prior to the closing of such Acquisition is equal to or greater than three (3) times the
then-effective Warrant Price.

As used in this Section 1.6, “Affiliate” shall mean any person or entity that owns or
controls directly or indirectly ten percent (10%) or more of the stock of Company, any person or
entity that controls or is controlled by or is under common control with such persons or entities,
and each of such person’s or entity’s officers, directors, joint venturers or partners, as
applicable.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the
outstanding shares of the Class payable in common stock or other securities, then upon exercise of
this Warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total
number and kind of securities to which Holder would have been entitled had Holder owned the Shares
of record as of the date the dividend occurred. If the Company subdivides the outstanding shares
of the Class by reclassification or otherwise into a greater number of shares, the number of Shares
purchasable hereunder shall be proportionately increased and the Warrant Price shall be
proportionately decreased. If the outstanding shares of the Class are combined or consolidated, by
reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be
proportionately increased and the number of Shares shall be proportionately decreased.

2.2 Reclassification, Exchange, Combinations or Substitution. Upon any
reclassification, exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall
be entitled to receive, upon exercise or conversion of this Warrant, the number and kind of
securities and property that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or other event, and the
Warrant Price shall be adjusted proportionately. The Company or its successor shall
promptly issue to Holder an amendment to this Warrant setting forth the number and kind of
such new securities or other property issuable upon exercise or conversion of this Warrant as a
result of such reclassification, exchange, substitution or other event that results in a change of
the number and/or class of securities issuable upon exercise or conversion of this Warrant. The
amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may
be practicable to the adjustments provided for in this Article 2 including, without limitation,
adjustments to the Warrant Price and to the number of securities or property issuable upon exercise
of the new Warrant. The provisions of this Article 2.2 shall similarly apply to successive
reclassifications, exchanges, substitutions, or other events.

 

3

 

2.3 [Intentionally Omitted].

2.4 No Impairment. The Company shall not, by amendment of its Certificate of
Incorporation or through a reorganization, transfer of assets, consolidation, merger, dissolution,
issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed under this Warrant by the Company,
but shall at all times in good faith assist in carrying out of all the provisions of this Article 2
and in taking all such action as may be necessary or appropriate to protect Holder’s rights under
this Article against impairment; provided, however, that notwithstanding the foregoing, nothing in
this Section 2.4 shall restrict or impair the Company’s right to effect changes to the rights,
preferences, and privileges associated with the Shares with the requisite consent of the
stockholders as may be required to amend the Certificate of Incorporation from time to time so long
as such amendment affects the rights, preferences, and privileges granted to Holder associated with
the Shares in the same manner as the other holders of outstanding shares of the Class.

2.5 Fractional Shares. No fractional Shares shall be issuable upon exercise or
conversion of the Warrant and the number of Shares to be issued shall be rounded down to the
nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the
Warrant, the Company shall eliminate such fractional share interest by paying Holder the amount
computed by multiplying the fractional interest by the fair market value of a full Share.

2.6 Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Class
and/or number of Shares, the Company shall promptly notify Holder in writing, and, at the Company’s
expense, promptly compute such adjustment, and furnish Holder with a certificate of its Chief
Financial Officer setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant
Price, Class and number of Shares in effect upon the date thereof and the series of adjustments
leading to such Warrant Price, Class and number of Shares.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

3.1 Representations and Warranties. The Company represents and warrants to, and
agrees with, the Holder as follows:

(a) All Shares which may be issued upon the exercise of the purchase right represented by this
Warrant shall, upon issuance, be duly authorized, validly issued, fully paid and non-assessable,
and free of any liens and encumbrances except for restrictions on transfer provided for herein or
under applicable federal and state securities laws.

 

4

 

3.2 Notice of Certain Events. If the Company proposes at any time (a) to declare any
dividend or distribution upon the outstanding shares of the same class and series as the Shares,
whether in cash, property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for subscription or sale pro rata to the holders of the outstanding shares of the same
class and series as the Shares any additional shares of any class or series of the Company’s stock;
(c) to effect any reclassification, reorganization or recapitalization of the outstanding shares of
the Class; or (d) to effect an Acquisition or to liquidate, dissolve or wind up, then, in
connection with each such event, the Company shall give Holder notice thereof at the same time and
in the same manner as the Company notifies the holders of the outstanding shares of the Class
thereof. Company will also provide information requested by Holder reasonably necessary to enable
the Holder to comply with the Holder’s accounting or reporting requirements, subject to Holder
being bound by customary confidentiality obligations.

3.3 No Shareholder Rights. Except as provided in this Warrant, Holder will not have
any rights as a shareholder of the Company until the exercise of this Warrant.

ARTICLE 4. REPRESENTATIONS, WARRANTIES OF THE HOLDER.

The Holder represents and warrants to the Company as follows:

4.1 Purchase for Own Account. This Warrant and the securities to be acquired upon
exercise of this Warrant by Holder will be acquired for investment for Holder’s account, not as a
nominee or agent, and not with a view to the public resale or distribution within the meaning of
the Act. Holder also represents that it has not been formed for the specific purpose of acquiring
this Warrant or the Shares.

4.2 Disclosure of Information. Holder has received or has had full access to all the
information it considers necessary or appropriate to make an informed investment decision with
respect to the acquisition of this Warrant and its underlying securities. Holder further has had
an opportunity to ask questions and receive answers from the Company regarding the terms and
conditions of the offering of this Warrant and its underlying securities and to obtain additional
information (to the extent the Company possessed such information or could acquire it without
unreasonable effort or expense) necessary to verify any information furnished to Holder or to which
Holder has access.

4.3 Investment Experience. Holder understands that the purchase of this Warrant and
its underlying securities involves substantial risk. Holder has experience as an investor in
securities of companies in the development stage and acknowledges that Holder can bear the economic
risk of such Holder’s investment in this Warrant and its underlying securities and has such
knowledge and experience in financial or business matters that Holder is capable of evaluating the
merits and risks of its investment in this Warrant and its underlying securities and/or has a
preexisting personal or business relationship with the Company and certain of its officers,
directors or controlling persons of a nature and duration that enables Holder to be aware of the
character, business acumen and financial circumstances of such persons.

4.4 Accredited Investor Status. Holder is an “accredited investor” within the meaning
of Regulation D promulgated under the Act.

4.5 The Act. Holder understands that this Warrant and the Shares issuable upon
exercise or conversion hereof have not been registered under the Act in reliance upon a specific
exemption therefrom, which exemption depends upon, among other things, the bona
fide nature of the Holder’s investment intent as expressed herein. Holder understands that
this Warrant and the Shares issued upon any exercise or conversion hereof must be held indefinitely
unless subsequently registered under the Act and qualified under applicable state securities laws,
or unless exemption from such registration and qualification are otherwise available.

ARTICLE 5. MISCELLANEOUS.

5.1 Term: This Warrant is exercisable in whole or in part at any time and from time
to time on or before the Expiration Date.

5.2 Legends. This Warrant and the Shares (and the securities issuable, directly or
indirectly, upon conversion of the Shares, if any) shall be imprinted with a legend in
substantially the following form:

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE
SECURITIES LAWS OF ANY STATE AND, EXCEPT FOR AND PURSUANT TO THE
PROVISIONS OF ARTICLE 5 OF THAT CERTAIN WARRANT TO PURCHASE STOCK
ISSUED BY THE COMPANY TO OXFORD FINANCE LLC DATED AS OF AUGUST 2,
2011 MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR
HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND
APPLICABLE STATE SECURITIES LAWS OR, IN THE OPINION OF LEGAL COUNSEL
IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE
SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS
EXEMPT FROM REGISTRATION.

5.3 Compliance with Securities Laws on Transfer. This Warrant and the Shares issuable
upon exercise of this Warrant (and the securities issuable, directly or indirectly, upon conversion
of the Shares, if any) may not be transferred or assigned in whole or in part without compliance
with applicable federal and state securities laws by the transferor and the transferee (including,
without limitation, the delivery of investment representation letters and legal opinions reasonably
satisfactory to the Company, as reasonably requested by the Company). The Company shall not
require Holder to provide an opinion of counsel if the transfer is to any “affiliate” (as such term
is defined in Regulation D promulgated under the Act) of Holder, provided that any such transferee
is an “accredited investor” as defined in Regulation D promulgated under the Act. Additionally,
the Company shall also not require an opinion of counsel if there is no material question as to the
availability of an exemption to registration under Rule 144, including without limitation, the
availability of current information as referenced in Rule 144(c), Holder represents that it has
complied with Rule 144(d) and (e) in reasonable detail, the selling broker represents that it has
complied with Rule 144(f), and the Company is provided with a copy of Holder’s notice of proposed
sale.

5.4 Transfer Procedure. After receipt by Holder of the executed Warrant, Oxford may
transfer all or part of this Warrant to one or more of Oxford’s affiliates (each, an “Oxford
Affiliate”), by execution of an Assignment substantially in the form of Appendix 2. Subject to the
provisions of Article 5.3 and upon providing the Company with written notice,
Oxford, any such Oxford Affiliate and any subsequent Holder may transfer all or part of this
Warrant or the Shares issuable upon exercise of this Warrant (or the securities issuable directly
or indirectly, upon conversion of the Shares, if any) to any transferee, provided, however, in
connection with any such transfer, the Oxford Affiliate(s) or any subsequent Holder will give the
Company notice of the portion of the Warrant being transferred with the name, address and taxpayer
identification number of the transferee and Holder will surrender this Warrant to the Company for
reissuance to the transferee(s) (and Holder if applicable). The Company may refuse to transfer
this Warrant or the Shares to any person who directly competes with the Company (as determined by
Holder), unless, in either case, the stock of the Company is publicly traded. Any transferee shall
take this Warrant subject to all provisions and restrictions contained herein.

5.5 Notices. All notices and other communications from the Company to the Holder, or
vice versa, shall be deemed delivered and effective when given personally or mailed by first-class
registered or certified mail, postage prepaid, at such address as may have been furnished to the
Company or the Holder, as the case may (or on the first business day after transmission by
facsimile) be, in writing by the Company or such Holder from time to time. Effective upon receipt
