(B) If the Cumulative Sales Revenue is at least equal to the Earn-Out Revenue Floor as set
forth on Schedule 2.1(c) (calculated as 80% of the Full Earn-Out Revenue Target; such amount, the Earn-Out Revenue Floor) but less than the Full Earn-Out Revenue Target, an aggregate cash payment between zero
and $11,500,000 shall be payable as the Sales Revenue Earn-Out, which amount shall be calculated proportionally by interpolating between such amounts by the portion of the Cumulative Sales Revenue in excess of the Earn-Out Revenue Floor as compared
to the Earn-Out Revenue Range as set forth on Schedule 2.1(c) (calculated as 20% of the Full Earn-Out Revenue Target; such amount, the Earn-Out Revenue Range), determined by multiplying $11,500,000 by a
quotient, the numerator of which is the portion of the Cumulative Sales Revenue in excess the Earn-Out Revenue Floor and the denominator which is the Earn-Out Revenue Range.

(C) If the Cumulative Sales Revenue is less than the Earn-Out Revenue Floor, the amount of the Sales Revenue Earn-Out shall be zero.

For purposes of this Agreement, the Stub Sales Revenue Certificate shall mean a certificate delivered by Seller Representative to Parent sixty (60) Business Days following
the Closing setting forth the sales revenue of Target for the Legacy Products during the Stub Period (the Stub Sales Revenue). The Stub Sales Revenue Certificate shall be certified by Seller Representative as to the
accuracy of such certificate as of the date of delivery. Parent shall review the calculation of the Stub Sales Revenue as set forth on the Stub Sales Revenue Certificate concurrently with the audit of its 2011 fiscal year and shall, within thirty
(30) Business Days following completion of the audit of its financial statements for its 2011 fiscal year, provide to Seller Representative a written confirmation of its agreement or disagreement with the amount of Stub Sales Revenue provided
in the Stub Sales Revenue Certificate. If Parent shall disagree with the amount of Stub Sales Revenue provided in the Stub Sales Revenue Certificate, Parent and Seller Representative shall mutually review the matter and negotiate in good faith for
up to fifteen (15) Business Days (or such other period of time as the parties mutually agree) to attempt to agree on the calculation of the Stub Sales Revenue. If the parties are unable to agree on the calculation of Stub Sales Revenue within
the fifteen (15) Business Day period specified in the preceding sentence, then the disputed portion(s) of such calculation shall be immediately submitted to a firm of independent certified public accountants mutually acceptable to Parent and
Seller Representative for resolution, the fees of which shall be borne in proportion to the extent Parent, on the one hand, and Sellers, on the other hand, are found to be the non-prevailing party as determined by such accounting firm.
For purposes of the preceding sentence, the extent to which Parent or Sellers are a non-prevailing party shall be determined as a percentage, with (i) the numerator being (x) with respect to Parent, the amount by which
Parents calculation of the Stub Sales Revenue is less than the amount determined by the firm of independent certified public accountants and (y) with respect to Sellers, the amount by which Seller Representatives calculation of the
Stub Sales Revenue is greater than the amount determined by the firm of independent certified public accountants, and (ii) the denominator being the amount of Stub Sales Revenue in dispute. In the event any partys percentage as a
non-prevailing party is greater than 100%, all of such fees shall be proportioned to such party. Notwithstanding the foregoing, if the firm of independent certified public accountants otherwise determines that the foregoing allocation of
responsibility for fees does not adequately address the dispute at issue and the non-prevailing party cannot be adequately determined as such, then such fees shall be borne equally by the parties. Any decision of such accounting firm with respect to
the disputed portion(s) of the calculation of Stub Sales Revenue shall be final and binding on the parties hereto and may not be submitted to arbitration. Sellers shall fully and promptly cooperate with Parent in providing any information requested
by Parent for review of the Stub Sales Revenue, including any work papers utilized in determining the Stub Sales Revenue.

in the foregoing clause and (z) in Parents audited financial statements for fiscal year 2012 (such Adjusted EBITDA for the combined fiscal years 2011 and 2012, the Cumulative EBITDA). For purposes of this
Agreement, EBITDA shall mean the net income/(loss) as reflected in the Parents audited financial statements, less interest, taxes, depreciation and amortization as determined under U.S. GAAP as reflected in
Parents audited financial statements and Adjusted EBITDA shall mean EBITDA as adjusted by Parent each year to exclude from expenses the following: (a) Parents U.S. research and development expenses
(excluding any depreciation and amortization already adjusted for); (b) any amounts paid by Parent as an upfront licensing fee for new products which Parent or Target may decide to sell or distribute after Closing; (c) any amounts
attributable as share based compensation expenses of Target for grants made to employees of Target for post-Closing retention purposes; (d) any legal and forensic accounting costs incurred and payable by Parent, any fines or penalties assessed
against Parent by any Governmental Authority and payable, or any settlement amounts agreed to by Parent with any Governmental Authority and payable with respect to the pending formal, non-public investigation being conducted by the U.S. Securities
and Exchange Commission (SEC); (e) any legal, auditing or financial advisor costs payable to third parties and incurred by Parent prior to or on the date hereof for the acquisition contemplated under this Agreement;
(f) any legal, auditing or financial advisor costs payable to third parties and incurred after the date hereof by Parent in connection with any negotiation of any potential Parent Change in Control Transaction, in each case as determined in
Parents financial statement consolidation included in the work papers utilized in Parents audited financial statements; and (g) milestone payments that may be required to be paid in the Earn-Out Period by Target to its partners for
regulatory success, net of amounts amortized by Parent. The EBITDA Earn-Out shall be determined as follows:

(A) If the
Cumulative EBITDA is equal to or greater than the Full Earn-Out EBITDA Target as set forth on Schedule 2.1(c) (such amount the Full Earn-Out EBITDA Target), an aggregate cash amount equal to $11,500,000 shall be
payable as the EBITDA Earn-Out.

(B) If the Cumulative EBITDA is at least equal to the Earn-Out EBITDA Floor as set forth on
Schedule 2.1(c) (calculated as eighty percent (80%) of the Full Earn-Out EBITDA Target; such amount, the Earn-Out EBITDA Floor) but less than the Full Earn-Out EBITDA Target, an aggregate cash payment
between zero and $11,500,000 shall be payable as the EBITDA Earn-Out, which amount shall be calculated proportionally by interpolating between such amounts by the portion of the Cumulative EBITDA in excess of the Earn-Out EBITDA Floor as compared to
the Earn-Out EBITDA Range as set forth on Schedule 2.1(c) (calculated as 20% of the Full Earn-Out EBITDA Target; such amount, the Earn-Out EBITDA Range), determined by multiplying $11,500,000 by a quotient, the
numerator of which is the portion of the Cumulative EBITDA in excess of the Earn-Out EBITDA Floor and the denominator which is the Earn-Out EBITDA Range.

(C) If the Cumulative EBITDA is less than the Earn-Out EBITDA Floor, the amount of the EBITDA Earn-Out shall be zero.

(D) If the Cumulative EBITDA is greater than the Full Earn-Out EBITDA Target, subject to
Section 2.1(d), in addition to the amount payable under Section 2.1(c)(ii)(A), an additional amount between zero and $10,000,000 shall be payable (as calculated, the EBITDA Overperformance Amount), with such
amount calculated proportionally by interpolating between such amounts by the portion of by which the Cumulative EBITDA exceeds the Full Earn-Out EBITDA Target as compared to the Earn-Out EBITDA Range, determined by multiplying $10,000,000 by a
quotient, the numerator of which is the portion of the Cumulative EBITDA in excess of the Full Earn-Out EBITDA Target and the denominator which is the Earn-Out EBITDA Range. Notwithstanding the foregoing, in the event the Cumulative EBITDA exceeds
the Earn-Out EBITDA Cap as set forth on Schedule 2.1(c) (calculated as one hundred and twenty percent (120%) of the Full Earn-Out EBITDA, such amount, the Earn-Out EBITDA Cap), the EBITDA Overperformance
Amount shall equal $10,000,000.

(E) For purposes of this Agreement, the Stub EBITDA Certificate
shall mean a certificate delivered by Seller Representative to Parent sixty (60) Business Days following the Closing setting forth Targets EBITDA in the Stub Period (the Stub EBITDA). The Stub EBITDA Certificate
shall be certified by Seller Representative as to the accuracy of such certificate as of the date of delivery. Parent shall review the calculation of the Stub EBITDA as set forth on the Stub EBITDA Certificate concurrently with the audit of its 2011
fiscal year and shall, within thirty (30) Business Days following completion of the audit of its financial statements for its 2011 fiscal year, provide to Seller Representative a written confirmation of its agreement or disagreement with the
amount of Stub EBITDA provided in the Stub EBITDA Certificate. If Parent shall disagree with the amount of Stub EBITDA provided in the Stub EBITDA Certificate, Parent and Seller Representative shall mutually review the matter and negotiate in good
faith for up to fifteen (15) Business Days (or such other period of time as the parties mutually agree) to attempt to agree on the calculation of the Stub EBITDA. If the parties are unable to agree on the calculation of Stub EBITDA within the
fifteen (15) Business Day period specified in the preceding sentence, then the disputed portion(s) of such calculation shall be immediately submitted to a firm of independent certified public accountants mutually acceptable to Parent and Seller
Representative for resolution, the fees of which shall be borne in proportion to the extent Parent, on the one hand, and Sellers, on the other hand, are found to be the non-prevailing party as determined by such accounting firm. For
purposes of the preceding sentence, the extent to which Parent or Sellers are a non-prevailing party shall be determined as a percentage, with (i) the numerator being (x) with respect to Parent, the amount by which
Parents calculation of the Stub EBITDA is less than the amount determined by the firm of independent certified public accountants and (y) with respect to Sellers, the amount by which Seller Representatives calculation of the Stub
EBITDA is greater than the amount determined by the firm of independent certified public accountants, and (ii) the denominator being the amount of Stub EBITDA in dispute. In the event any partys percentage as a non-prevailing
party is greater than 100%, all of such fees shall be proportioned to such party. Notwithstanding the foregoing, if the firm of independent certified public accountants otherwise determines that the foregoing allocation of responsibility for
fees does not adequately address the dispute at issue and the non-prevailing party cannot be adequately determined as such, then such fees shall be borne equally by the parties. Any decision of such accounting firm with respect to the disputed
portion(s) of the calculation of Stub EBITDA shall be final and binding on the parties hereto. Sellers shall fully and promptly cooperate with Parent in providing any information requested by Parent for review of the Stub EBITDA, including any work
papers utilized in determining the Stub Sales EBITDA.

Any amounts of Contingent Consideration determined as set forth above shall be subject
to modification set forth in paragraph (d) below and be paid in accordance with Sections 2.2(c), 2.2(d), 2.2(e), 2.2(f) and 2.2(g) below. Parents obligations to pay the Contingent Consideration shall be subject to reduction pursuant

zero and no increase of Contingent Consideration under Section 2.1(d)(i) nor reduction under Section 2.1(d)(ii) shall take effect regardless of whether the customer condition set forth in Schedule 2.1(d) is achieved or not achieved,
such that the amount of Contingent Consideration payable under this Agreement shall equal $23,000,000. Notwithstanding the foregoing, in the event Mr. Lotters termination is for Cause or, if without Cause, is approved by the majority of
the members of a committee of Parents Board of Directors consisting of Messrs. Peter Barrett, Gregg Lapointe and Jon Saxe (or such replacements on the committee as may be reasonably agreed to between either Mr. Barrett or Seller
Representative, on the one hand, and Parent on the other hand), the acceleration of the Contingent Payment provided for by this paragraph shall not be triggered. For purposes of clarity, except for an amendment that constitutes constructive or de
facto termination of Mr. Lotter, any amendment of the Employment Agreement or of Mr. Lotters employment agreed to between Mr. Lotter and Parent shall in each case not trigger the acceleration of the Contingent Payment provided
for by this paragraph. Any Contingent Consideration payable under this Section 2.2(e) shall be due and payable as soon as practicable after the completion of the 2012 Audit, subject to offset for any Damages payable pursuant to Section 9
hereof. To the extent Purchaser Indemnified Person has submitted in good faith a Claim Notice pursuant to Section 9.5 to Seller Representative with respect to a Claim which remains unresolved prior to date of payment of any Sales Revenue
Earn-Out or EBITDA Earn-Out, subject to Section 9.3, an amount equal to the Damages claimed in the Claim Notice shall be withheld from payment by Parent and set aside pending final resolution of the Claim Notice, after which Parent shall
release and pay any portions thereof which are not offset for any Damages payable pursuant to Section 9.

(f) Contingent Consideration Payment upon Failure of Board
Appointment. In the event Parent is unable to comply in all material respects with the requirements of Section 7.9 of this Agreement such that as a result, Sellers are unable to effect the designation of Seller Nominees to Parents
Board of Directors during any time in the Earn-Out Period, then as full and final settlement of the Contingent Payment amounts, each of the Sales Revenue Earn-Out and the EBITDA Earn-Out shall be deemed to equal $11,500,000, the EBITDA
Overperformance Amount shall be deemed to equal zero and no increase of Contingent Consideration under Section 2.1(d)(i) nor reduction under Section 2.1(d)(ii) shall take effect regardless of whether the customer condition set forth in
Schedule 2.1(d) is achieved or not achieved. Notwithstanding the foregoing, the acceleration of the Contingent Payment provided for by this paragraph shall not be triggered in the event Sellers do not vote any shares of Parent Common Stock
held or beneficially controlled by them in favor of the election of Seller Nominees where such shares, had they been voted in favor of Seller Nominees, would have otherwise resulted in the election of Seller Nominees. Any Contingent Consideration
payable under this Section 2.2(f) shall be due and payable as soon as practicable after the completion of the 2012 Audit, subject to offset for any Damages payable pursuant to Section 9 hereof. To the extent Purchaser Indemnified Person
has submitted in good faith a Claim Notice pursuant to Section 9.5 to Seller Representative with respect to a Claim which remains unresolved prior to date of payment of any Sales Revenue Earn-Out or EBITDA Earn-Out, subject to Section 9.3,
an amount equal to the Damages claimed in the Claim Notice shall be withheld from payment by Parent and set aside pending final resolution of the Claim Notice, after which Parent shall release and pay any portions thereof which are not offset for
any Damages payable pursuant to Section 9.

(g) Deferred Contingent Consideration Payment.

(i) With respect to Mr. Mark Lotter, the payment and delivery of the respective portion of any Contingent Consideration
(the Deferred Contingent Consideration) that may otherwise become due and payable to his holding company Spearing Limited under the terms of this Agreement shall be automatically deferred until the fifth
(5th) anniversary of the Closing Date in the event Mr. Lotter ceases at any time after the Closing Date through the date of payment of the Contingent Consideration to be an employee of Parent, Purchaser or one of their affiliates, except
as a result of such Mr. Lotters death, disability or termination by Parent, Purchaser or one of their affiliates without Cause, unless otherwise determined in writing by Parent in its sole discretion. Any Deferred Contingent Consideration
deferred pursuant to this Section 2.2(g) shall accrue simple interest from the date on which the Deferred Contingent Consideration was otherwise payable or deliverable pursuant to Section 2.2(c), 2.2(d), 2.2(e) and 2.2(f) of this Agreement
until the date of delivery of such Deferred Contingent Consideration pursuant to this Section 2.2(g), at the prime percentage rate as published by Silicon Valley Bank in effect on the date such amount was otherwise deliverable pursuant to
Section 2.2(c), 2.2(d) 2.2(e) and 2.2(f) of this Agreement and adjusted quarterly to the prime percentage rate as published by Silicon Valley Bank and in effect on the last Business Day of each calendar quarter thereafter until the date of
delivery of such Deferred Contingent Consideration pursuant to this Section 2.2(g). For the purposes of the immediately foregoing sentence, the value of any Deferred Contingent Consideration shall be calculated as of the date on which the
Deferred Contingent Consideration was otherwise deliverable pursuant to Section 2.2(c), 2.2(d), 2.2(e) and 2.2(f). Any such interest shall be paid in cash and shall be paid only on or after the date on which Parent delivers the Deferred
Contingent Consideration to Mr. Lotter pursuant to this Section 2.2(g).

of any of the following: (A) theft, fraud, dishonesty, gross negligence or willful misconduct by Mr. Lotter in connection with the performance of his duties pursuant to his Employment Agreement; (B) a willful breach of the material
terms of his Employment Agreement by Mr. Lotter; (C) a material failure to fulfill or perform his duties under his Employment Agreement, other than due to illness or injury, which breach or failure is not cured to the reasonable
satisfaction of the Board of Directors of Parent within thirty (30) days after written notice from the Board of Directors of Parent to Mr. Lotter; (D) conviction of a felony or a crime or civil violation which involves moral turpitude
or would be considered harmful to the reputation or goodwill of Parent, Purchaser, or any of its affiliates (or plea of guilty or nolo contendere); (E) a repeated or ongoing failure to comply with the reasonable directions and
instructions of the Board of Directors of Parent in connection with the performance of Mr. Lotters duties and responsibilities hereunder following an initial notice of warning from the Board of Directors of Parent with respect thereto
(provided, however, that his performance of duties as Seller Representative in itself, and not as an employee of Parent, Purchaser or their affiliates, shall not constitute failure to comply with the reasonable directions and instructions of the
Board of Directors of Parent); (F) use or possession of illicit drugs or abuse of alcohol, while performing duties for Parent, Purchaser, or one of its affiliates or while on the premises of Parent, Purchaser, or one of its affiliates; or
(G) commission of any act, or failure to act, in bad faith, which, in the reasonable determination of the Board of Directors of Parent, in any material respect impairs the reputation of, or in any material respect harms, Parent, Purchaser, or

2.3 Working Capital Adjustment to Purchase Price.

(a) Not later than three (3) Business Days prior to the Closing, Target shall provide Parent with an estimated
balance sheet of Target as of the Closing (the Estimated Closing Balance Sheet) and a statement of the estimated Closing Working Capital (as defined in Section 2.3(e) below) derived from the Estimated Closing Balance
Sheet (Estimated Closing Working Capital Statement), along with reasonable documentation supporting the calculation of the estimated Closing Working Capital. The Estimated Closing Balance Sheet and Estimated Closing Working
Capital Statement shall be prepared by Target in accordance with United States generally accepted accounting principles (U.S. GAAP) applied using the same accounting methods, practices, principles, policies and procedures,
with consistent classifications, judgments and valuation and estimation and accrual methodologies that were used in the preparation of the Financial Statements (as defined in Section 5.5 below) as if such Estimated Closing Balance Sheet and
Estimated Closing Working Capital Statement were being prepared as of a fiscal year end; provided, however, that in the event there is a conflict between U.S. GAAP and the classifications, judgments and valuation and estimation and accrual
methodologies that were used in the preparation of the Financial Statements, the classifications, judgments and valuation and estimation and accrual methodologies under U.S. GAAP shall be used in preparing the Estimated Closing Balance Sheet and
Estimated Closing Working Capital Statement.

(b) If the amount of Closing Working Capital as set forth on the
Estimated Closing Working Capital Statement is less than the Expected Working Capital Amount, an amount equal to the shortfall by which the Closing Working Capital as set forth on the Estimated Closing Working Capital Statement is less than the
Expected Working Capital Amount shall be deducted from the Cash Purchase Price to be paid at Closing.



11



---

(c) Parent shall have sixty (60) Business Days following Closing to
review the calculation of the Closing Working Capital as set forth on the Estimated Closing Working Capital Statement. Sellers shall fully and promptly cooperate with Parent in providing any information requested by Parent for review of the
Estimated Closing Working Capital Statement. The calculation of the Closing Working Capital as set forth on the Estimated Closing Working Capital Statement shall have been deemed to have been accepted by Parent unless within the sixty
(60) Business Day period after Closing Parent shall deliver to Seller Representative a balance sheet of Target as of the Closing (the Revised Closing Balance Sheet) and a statement of Closing Working Capital derived
from the balance sheet of Target as of the Closing (the Revised Closing Working Capital Statement). The Revised Closing Balance Sheet and the Revised Closing Working Capital Statement shall be prepared in accordance with
U.S. GAAP applied using the same accounting methods, practices, principles, policies and procedures, with consistent classifications, judgments and valuation and estimation and accrual methodologies that were used in the preparation of the Financial
Statements as if such Revised Closing Balance Sheet was being provided to auditors in connection with a fiscal year end; provided, however, that in the event there is a conflict between U.S. GAAP and the classifications, judgments and valuation and
estimation and accrual methodologies that were used in the preparation of the Financial Statements, the classifications, judgments and valuation and estimation and accrual methodologies under U.S. GAAP shall be used preparing the Revised Closing
Balance Sheet and the Revised Closing Working Capital Statement. Upon Parents delivery of the Revised Closing Balance Sheet and the Revised Closing Working Capital Statement to Seller Representative, the parties will mutually review the matter
and negotiate in good faith for up to fifteen (15) Business Days (or such other period of time as the parties mutually agree) to attempt to agree on the calculation of Closing Working Capital. If the parties are unable to agree on the
calculation of Closing Working Capital within the fifteen (15) Business Day period specified in the preceding sentence, then the disputed portion(s) of such calculation shall be immediately submitted to a firm of independent certified public
accountants mutually acceptable to Parent and Seller Representative for resolution, the fees of which shall be shared equally between Parent, on the one hand, and Sellers collectively, on the other hand. Any decision of such accounting firm with
respect to the disputed portion(s) of the calculation of Closing Working Capital shall be final and binding on the parties hereto.

(d) No later than five (5) Business Days following the final determination of Closing Working Capital in accordance with Section 2.3(c) above, the Cash Purchase Price shall be adjusted as
provided herein to reflect the Closing Working Capital determined. If the Closing Working Capital as finally determined is greater than the amount equal to the Expected Working Capital Amount less the amount, if any, of any shortfall previously
deducted from the Cash Purchase Price in accordance with Section 2.3(b) above, then (i) the amount by which the Closing Working Capital Amount exceeds such amount shall each be added to the Purchase Price and (ii) Parent shall pay to
Sellers, or cause Purchaser or one of its affiliates to pay to Sellers, an aggregate amount of such excess in accordance with Sellers Pro-rata Interests along with release of the Working Capital Escrow Amount. For purposes of this Agreement,
Pro-rata Interest shall mean the percentage interest equal to the number of Shares held by Seller immediately prior to Closing divided by the aggregate number of Shares outstanding immediately prior to Closing, which
percentage shall be set forth across each Sellers name in the Allocation Schedule under the column entitled Pro-rata Interest. If the Closing Working Capital as finally determined is less than the amount equal to the Expected
Working Capital Amount less the amount, if any, of any shortfall previously deducted from the Cash Purchase Price in accordance with Section 2.3(b) above, then the amount of shortfall shall be paid to Parent (or if Purchaser shall otherwise
determine, to Purchaser or one of its affiliates) out of the Working Capital Escrow Amount in accordance with Sellers Pro-rata Interests. In the event that the portion of the Working Capital Escrow Amount that is remaining after any payments
owed to Parent pursuant to Section 2.3(c) have been made is insufficient to cover the amount owed to Parent pursuant to this Section 2.3(d), such shortfall shall be paid by Sellers, in accordance with each Sellers Pro-rata Interest
of such shortfall amount, to Parent (or if Purchaser shall otherwise determine, to Purchaser or one of its affiliates) within ten (10) Business Days after final determination. In the event the full amount owing to Parent is not paid within such
ten (10) Business Day period, Parent shall have a right to satisfy such amount at its sole discretion out of the Indemnification Escrow Amount, which payment shall be apportioned in accordance with each Sellers Pro-rata Interest of the
Indemnification Escrow Amount.

(i) Closing Working Capital means (A) the Included Current Assets of Target less (B) the Included
Current Liabilities of Target, determined as of the Closing.

(ii) Expected Working Capital Amount
means $8,000,000; provided, however, that

(A) any amounts of the following audit-related fees shall not be included in the

2009 and 2010 using Targets current firm of independent certified public accountants, any incremental fees incurred or to be incurred by Target to such firm for the audits of the fiscal years 2009 and 2010 as conducted by such firm which are
solely a result of Parents requirement for an unqualified audit opinion for the accounting for share based reserves (provided, however, that any non-incremental fees incurred or to be incurred shall be accrued in the Included Current
Liabilities), or (2) if Parent elects to have Target continue with the completion of the preparation of audited financial statements for Targets fiscal years 2009 and 2010 with a separate firm of independent certified public accountants
as chosen by Parent in its sole discretion, all fees incurred by Target to such firm for the audits of the fiscal years 2009 and 2010 as conducted by such firm. Target shall proceed with any engagement as so elected by Parent, which election shall
be made by Parent in its sole discretion.

(B) any amounts of Targets pre-paid liabilities existing at Closing for
previous in-licensed product payments shall be included in the Included Current Assets of Target in a manner consistent with the manner accounted for in Targets Financial Statements regardless of their accounting treatment under U.S. GAAP.

(iii) Included Current Assets means cash, cash equivalents, short-term investments, accounts
receivable, net, other receivables and pre-paid expenses to the extent recognized by Parent under U.S. GAAP of Target due within one year; provided, however, Included Current Assets shall not include any deferred tax assets.

(iv) Included Current Liabilities means notes payable, accounts payable, accruals and other liabilities, and
other payables of Target as of the type historically included in Targets Financial Statements; provided, however, Included Current Liabilities shall not include any amounts to be paid for the Option Repurchase Amount nor any deferred tax
liabilities.

2.4 Escrow and Adjustment Payments. The portion of the Initial Consideration
otherwise to be paid to Sellers at Closing shall be reduced by (i) an amount equal to fifteen percent (15%) of the Cash Purchase Price and fifteen percent (15%) of the Share Purchase Price (the Indemnification Escrow
Amount), which Indemnification Escrow Amount shall be held in escrow by the Escrow Agent pursuant to the terms of the Escrow Agreement for the period beginning on the Closing Date and ending on the date that is eighteen
(18) months after the Closing Date (the Survival Period) to satisfy any claims by Purchaser for indemnification pursuant to Section 9 hereof, and (ii) an amount equal $500,000 (the Working Capital
Escrow Amount), which Working Capital Escrow Amount shall be held in escrow by the Escrow Agent pursuant to the terms of the Escrow Agreement to satisfy any amounts owed by Sellers to Purchaser pursuant to Section 2.3(d) hereof.
The Indemnification Escrow Amount and the Working Capital Escrow Amount shall be escrowed by Sellers in proportion to each Sellers Pro-Rata Interest, as set forth under the captions Indemnification Escrow Amount and Working
Capital Escrow Amount set forth next to such Sellers name on the Allocation Schedule. Within ten (10) Business Days of the final determination of the Closing Working Capital in accordance with Section 2.3(c), the portion of the
Working Capital Escrow Amount and accrued interest remaining after satisfaction of amounts owed to Parent, Purchaser or one of their affiliates pursuant to Section 2.3(d) hereof (if any) shall be released from the escrow and delivered to each
Seller or such Sellers representative in accordance with each Sellers Pro-rata Interest. Within ten (10) Business Days after the date that is twelve (12) months after the Closing Date, 50% of the Indemnification Escrow Amount
and accrued interest remaining after satisfaction of claims (if any) made in accordance with Section 9.4 and Section 9.5 prior to the date that is twelve (12) months after the Closing Date, if any, shall be released from escrow and
delivered to such Seller; provided, however, should any indemnification claim made prior to the date that is twelve (12) months after the Closing Date fail to reach final determination and satisfaction prior to the date that is
twelve (12) months after the Closing Date, a portion of the 50% of the Indemnification Escrow Amount and accrued interest remaining that would otherwise be released pursuant to the foregoing that the parties reasonably determine in good faith
as sufficient to satisfy 50% of all amounts with respect to such indemnification claim shall be retained in escrow pending final resolution of such claim in accordance with the provisions of the Escrow Agreement. Within ten (10) Business Days
after the expiration of the Survival Period, the Indemnification Escrow Amount and accrued interest remaining after satisfaction of claims made in accordance with Section 9.4 and Section 9.5 prior to the expiration of the Survival Period
pursuant to the immediately preceding sentence, if any, shall be released from escrow and delivered to such Seller; provided, however, should any indemnification claim made prior to the expiration of the Survival Period fail to reach
final determination and satisfaction prior to the expiration of the Survival Period, a portion of the Indemnification Escrow Amount that the parties reasonably determine in good faith as sufficient to satisfy all amounts with respect to such
indemnification claim shall be retained in escrow pending final resolution of such claim in accordance with the provisions of the Escrow Agreement.

2.5 Payment of Transfer Taxes and Fees. All transfer, documentary, sales, use, stamp and registration taxes, and all conveyance fees, recording charges and other fees and charges (including any
penalties and interest) incurred in connection with the consummation of the transactions contemplated by this Agreement, shall be borne equally by Sellers on the one hand and Purchaser on the other hand.

For purposes of this Section 5, unless the context expressly indicates otherwise, references to the Target shall be deemed to include any Subsidiaries of Target, including the China Sub, even if not separately mentioned. As used

confirms its intention to become a specialty pharmaceutical company primarily focused on the PRC. Parent confirms that its SCV-07 Phase II development spending of oral mucositis (OM) is expected to conclude after the

Parents fiscal years 2011 and 2012. However, if the SCV-07 Phase II trial is successful and the SCV-07 asset demonstrates strategic value to Parent or its Subsidiaries, as may be reasonably determined by Parent, Parent shall pursue
further development through a self-funding model where no further material funding from Parent will be required. Furthermore, Parent intends that such SCV-07 asset will be available also for PRC-based development.

permit the resale thereof, and in connection therewith shall use its reasonable best efforts to prepare and file a registration statement (the Registration Statement) with the SEC with respect to the Registrable Securities
as soon as practicable after the Closing Date and shall use its reasonable best efforts to cause the Registration Statement to become effective prior to the expiration of the Lock-Up Period; provided, however, that each holder of
Registrable Securities (Holder) shall provide all such information and materials to Parent and take all such action as may be necessary in order to permit Parent to comply with all applicable requirements of the SEC and to
obtain any desired acceleration of the effective date of such Registration Statement. Such provision of information and materials is a condition precedent to the obligations of Parent pursuant to this Section 7.11. In addition, in the event
Parent is unable to file a Form 8-K including any required financial statements of Target within the 71 calendar day period after which the initial Form 8-K is required to be filed for the consummation of the transactions contemplated by this
Agreement and such failure to timely file is due to the failure of Parent and Target to complete any audited financial statements of Target required to be filed, then the Registration Statement shall not be required to become effective prior to the
expiration of the Lock-Up Period but only at such time as may be reasonable practicable thereafter and 50% of the fees and costs incurred for Parents Form S-1 registration statement shall be shared by Sellers and deducted from the

the shares registered thereunder are sold or may be sold under Rule 144 in one three-month period (assuming compliance by Holders with the provisions thereof) or (ii) eighteen (18) months after the Closing, subject to Section 7.11(b);
(ii) prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary, and comply with the provisions of the Securities Act with respect to the sale
or other disposition of all securities proposed to be registered in the Registration Statement until the termination of effectiveness of the Registration Statement; and (iii) for so long as Parent is required to cause the Registration Statement
to remain effective, furnish to each Holder such number of copies of any prospectus (including any preliminary prospectus and any amended or supplemented prospectus) as required by the Securities Act, and such other documents as each Holder may
reasonably request in order to effect the offering and sale of the shares of Registrable Securities to be offered and sold.

(b) Suspension of Effectiveness. Notwithstanding any other provision
of this Section 7.11, Parent shall have the right at any time to require that all Holders suspend open market offers and sales of Registrable Securities whenever, and for so long as, in the reasonable, good-faith judgment of Parent after
consultation with counsel, there is in existence material undisclosed information or events with respect to Parent (the Suspension Right). In the event Parent exercises the Suspension Right, such suspension will continue
for the period of time reasonably necessary for disclosure to occur at a time that is not materially detrimental to Parent or until such time as the information or event is no longer material, each as reasonably determined in good faith by Parent
after consultation with counsel. Parent will promptly give the Seller Representative notice, in a writing signed by an executive officer of Parent, of any such suspension (the Suspension Notice). Parent agrees to notify the
Seller Representative promptly upon termination of the suspension (the Resumption Notice). Upon receipt of either a Suspension Notice or Resumption Notice, Parent shall immediately notify each Holder concerning the status
of the Registration Statement. The period during which Parent is required to cause the Registration Statement to remain effective shall be extended by a period equal in length to any and all periods during which open market offers and sales of
Registrable Securities are suspended pursuant to exercise of the Suspension Right.

(c) Expenses.

registration and filing fees, exchange listing fees, printing expenses, transfer agents and registrars fees, the fees and disbursements of Parents outside counsel and independent accountants. Sellers shall be responsible for any
fees or disbursements of their own counsel incurred in connection with the registration of Registrable Securities pursuant to this Section 7.11.

7.12 Further Assurances. From time to time, at Parent and Purchasers request, whether on or after the Closing Date and without further consideration, each Seller shall execute and deliver or
cause to be executed and delivered such further instruments of conveyance and transfer and take such other action as Parent and Purchaser reasonably may require more effectively to convey and transfer to Parent and Purchaser title to the Shares and
to effectuate the transactions contemplated hereby. From time to time after the Closing, at Targets request, whether on or after the Closing Date and without further consideration, Parent and Purchaser shall take such action (including,

aware of a third-party claim which could result in Damages for which it or any other Purchaser Indemnified Person may be entitled to indemnification hereunder, such Purchaser Indemnified Person shall promptly and without delay notify Seller
Representative of such third-party claim, and Sellers shall be entitled, at their own expense, to participate in any defense of such claim; provided, however, that no delay or failure on the part of Parent or Purchaser in notifying
Seller Representative shall relieve Sellers from any obligation hereunder unless Sellers are thereby prejudiced (and then solely to the extent of such prejudice). Purchaser Indemnified Persons shall be entitled to assume the defense of such
third-party claim with counsel of its selection. Purchaser Indemnified Persons shall keep Seller Representative informed of all material developments and events relating to such Claim, and shall deliver to Seller Representative, within five
(5) Business Days after Purchaser Indemnified Persons receipt thereof, copies of all notices, correspondence and documents (including court papers) received by Purchaser relating to such Claim. Purchaser Indemnified Person shall have the
right in its sole discretion to settle any such Claim; provided, however, in the event that the Seller Representative has not consented to any such settlement in writing prior to such settlement, Seller Representative shall retain the
right to object under this Section 9 to the amount of any Claim by Purchaser Indemnified Person for indemnity with respect to such settlement, including the reasonableness of the amount of such settlement; provided further,
however, that in the event that Seller Representative has consented in writing to any settlement of any third-party claim to which any Purchaser Indemnified Person is entitled to indemnification under this Section 9, Seller
Representative shall have no power or authority to object under any provision of this Section 9 to the amount of any Claim by Parent or Purchaser for indemnity with respect to such settlement.

9.7 Limitation on Indemnity; Exclusivity of Remedy. Except in respect of claims based upon fraud or violation of the federal
securities laws, the indemnification accorded by this Section 9 shall be the sole and exclusive remedy of the parties indemnified under this Section 9; provided, however, that any Damages recovered by Purchaser Indemnified
Persons for any Claim made pursuant to this Section 9 shall be reduced by the amount of recovery proceeds from any insurance policy (including title insurance) held by Target covering such Claim and actually paid to Purchaser Indemnified
Persons; provided further, however, that should such recovery from the insurance policy result in an increase to such policys insurance premium, such reduction to Damages shall be offset by the total amount of such premium
increase. Notwithstanding the foregoing, in the event of any breach or failure in performance after the Closing Date of any covenant or agreement, a non-breaching party shall also be entitled to seek specific performance, injunction or other
equitable relief. The covenants of any party shall terminate according to the terms of such covenant and the expiration of the applicable statute of limitations.

9.8 Tax Treatment of Indemnification Payments. Any indemnification payments made pursuant to this Agreement shall be treated for Tax purposes as an adjustment to the purchase price for the Shares.

10. Seller Representative.

10.1 Designation and Replacement of Seller Representative. Sellers have agreed that it is desirable to designate a representative to act on behalf of Sellers for certain limited purposes, as
specified herein (the Seller Representative) as Sellers agent, proxy and attorney-in-fact. Sellers hereby appoint and designate Mark Lotter as the initial Seller Representative. The appointment and agency created
hereby is irrevocable, and shall be deemed to be coupled with an interest. Seller Representative may resign at any time, but no resignation shall be effective until a new Seller Representative, who shall be reasonably able to perform the duties of
the Seller Representative and reasonably satisfactory to Parent and Purchaser, has been appointed and agrees in a writing delivered to Parent and Purchaser to be bound by the terms of this Agreement. Subject to the foregoing, in the event of the
death, incapacity, resignation or removal of a Seller Representative, a new Seller Representative shall be appointed by a vote or consent of a majority of Sellers (pro rata in accordance with their Pro-rata Interest), such appointment to become
effective upon the later of the date set forth in notice of such vote or written consent or the date such notice of such vote or written consent is received by Parent and Purchaser or Target. All decisions, actions, consents and instructions by the
Seller Representative shall be binding upon all of Sellers, and no Seller shall have the right to object to, dissent from, protest or otherwise contest the same. Parent and Purchaser shall be entitled to rely on any action taken or decisions made by
the Seller Representative, as being the action or decision of Sellers, and Parent and Purchaser is hereby relieved from any liability to any Person for acts done by them in accordance with any such decision, act, consent or instruction.

10.2 Authority and Rights of the Seller Representative; Limitations on Liability. The
Seller Representative shall have such powers and authority as are necessary to carry out the functions assigned to it under this Agreement; provided, however, that the Seller Representative shall have no obligation to act on behalf of
Sellers, except as expressly provided herein or therein. Without limiting the generality of the foregoing, the Seller Representative shall have full power, authority and discretion (i) to negotiate, settle, compromise or take any other action
to otherwise handle any claim for indemnification by any Purchaser Indemnified Person pursuant to Section 9 hereof; (ii) to resolve any and all post-closing disputes by and on behalf of Sellers; and (iii) to act on behalf of Sellers
with respect to any and all other matters hereunder. The Seller Representative shall have no liability to Parent, Purchaser, Target or Sellers with respect to actions taken or omitted to be taken in its capacity as the Seller Representative, except
with respect to the Seller Representatives gross negligence or willful misconduct. The Seller Representative shall at all times be entitled to rely on any directions received from a majority of Sellers. All decisions, actions, consents and
instructions by the Seller Representative shall be binding upon all of Sellers, and no Seller shall have the right to object to, dissent from, protest or otherwise contest the same.

10.3 Representations of the Seller Representative. The Seller Representative represents and warrants to Parent and Purchaser that
the Seller Representative has all requisite power and authority to execute and deliver this Agreement and to perform all obligations to be performed by it hereunder and to consummate the transactions contemplated hereby. This Agreement has been and
duly and validly executed and delivered by the Seller Representative and constitutes a legal, valid and binding obligation of the Seller Representative, enforceable against the Seller Representative in accordance with his or her respective terms,
except as enforcement may be limited by general principles of equity, whether considered in a Proceeding at law or in equity, and by applicable bankruptcy, insolvency, moratorium and similar laws affecting creditors rights generally. The
execution, delivery and performance by the Seller Representative of this Agreement and the consummation by the Seller Representative of the transactions contemplated hereby do not and will not (i) conflict with or violate any provision of law
applicable to the Seller Representative or by which any property or asset of the Seller Representative is bound or affected, (ii) conflict with, result in any breach of, constitute a default (or an event that, with notice or lapse of time or
both, would become a default) under, require any consent of any Person pursuant to, give to others any rights of termination, acceleration or cancellation of, or other change of any right or obligation or the loss of any benefit to which the Seller
Representative is entitled under, any provision of any agreement, indenture or other instrument to which the Seller Representative is a party of by which the Seller Representative or any of his or her assets may be bound, or (iii) result in the
creation or imposition of any Encumbrance on any assets of the Seller Representative or result in a violation or revocation of any license, permit, franchise, certificate, approval or other similar authorization affecting, or relating in any way to,
the assets or business of the Seller Representative from any Governmental Authority or other Person, except to the extent that the occurrence of any of the foregoing would not, individually or in the aggregate, reasonably be expected to have a
material adverse effect on the ability of the Seller Representative to perform his or her obligations under this Agreement.
