 1.5 Interest. The principal balance of each Advance shall bear interest thereon from the Advance
Date, precomputed at the Interest Rate based on a year consisting of 360 days, with interest computed daily based on the actual number of days in each month. The Interest Rate for each Advance will be fixed on the date of that Advance, and will
apply to that Advance for so long as it is outstanding, including during the period of amortization.

interest on each Advance on the first day of each month, beginning the month after the Advance Date. Borrower shall repay the aggregate principal balance that is outstanding on July 1, 2008 in thirty (30) equal monthly installments of
principal and interest beginning on July 1, 2008 and continuing on the first business day of each month thereafter; provided, however, if the Extension Event occurs on or prior to [*****], then Borrower shall repay the aggregate principal
balance that is outstanding on October 1, 2008 in thirty-three (33) equal monthly installments of principal and interest beginning October 1, 2008 and continuing on the first business day of each month thereafter. The entire principal
balance and all accrued but unpaid interest hereunder, shall be due and payable on the Maturity Date. Borrower shall make all payments under this Agreement without setoff, recoupment or deduction and regardless of any counterclaim or defense.

 1.7 Maximum Interest. Notwithstanding any provision in this Agreement, the Notes, or any other Loan Document, it is the
parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under the laws of the Commonwealth of
Massachusetts shall be deemed to be the laws relating to permissible rates of interest on commercial loans) (the “Maximum Rate”). If a court of competent jurisdiction shall finally determine that Borrower has actually paid to Lender an
amount of interest in excess of the amount that would have been payable if all of the Secured Obligations had at all times borne interest at the Maximum Rate, then such excess interest actually paid by Borrower shall be applied as follows:
first, to the payment of principal outstanding on the Notes; second, after all principal is repaid, to the payment of Lender’s accrued interest, costs, expenses, professional fees and any other Secured Obligations; and
third, after all Secured Obligations are repaid, the excess (if any) shall be refunded to Borrower. 
 1.8 Default Interest. In
the event any payment is not paid on the scheduled payment date, an amount equal to five percent (5%) of the past due amount shall be payable on demand; provided, however, for one (1) month per year, such fee shall not be due and payable
if any payment is not made on the scheduled payment date so long as such payment is made within ten (10) calendar days after the applicable scheduled payment date. In addition, upon the occurrence and during the continuation of an Event of
Default hereunder, all Secured Obligations, including principal, interest, compounded interest, and professional fees, shall bear interest at a rate per annum equal to the rate set forth in Section 2.3 plus five percent (5%) per annum. In
the event any interest is not paid when due hereunder, delinquent interest shall be added to principal and shall bear interest on interest, compounded at the rate set forth in Section 2.3 or Section 2.6, as applicable; provided, however,
for one (1) month per year, such interest shall not be added to principal and shall not bear interest on interest if such payment is not made when due hereunder so long as such payment is made within five (5) calendar days after the
applicable due date.

 1.9 Prepayment. At its option, upon five (5) business days prior written notice to Lender,
Borrower may prepay, in whole or in part, the outstanding Advances by paying all accrued interest on the principal portion of the Advance amount being prepaid, together with a prepayment charge equal to the following percentage of the Advance amount
being prepaid: if such Advance amount is prepaid in the first sixteen (16) months following the Closing Date, 5%; after sixteen (16) months but prior to thirty-two (32) months, 3%; and thereafter, 1% (each, a “Prepayment
Charge”). Borrower agrees that the Prepayment Charge is a reasonable calculation of Lender’s lost profits in view of the difficulties and impracticality of determining actual damages resulting from an early repayment of the Advances.
Borrower shall prepay the outstanding amount of all principal and accrued interest and the Prepayment Charge upon a Prepayment Event. 
 1.10
Fees. Borrower shall pay to Lender: 
 (a) Facility Fee. The fully earned, non-refundable Facility Fee on the

earlier of (a) the Maturity Date or (b) the acceleration of the Advances; 
 (d) Prepayment Charge. The
Prepayment Charge, if and when due hereunder; and 
 (e) Unused Line Fee. The Unused Line Fee, if and when due
hereunder. 
 SECURITY INTEREST 
 1.11 As
security for the prompt, complete and indefeasible payment when due (whether on the payment dates or otherwise) of all the Secured Obligations, Borrower grants to Lender a security interest in all of Borrower’s personal property now owned or
hereafter acquired, including the following: (collectively, the “Collateral”): (a) Receivables; (b) Equipment; (c) Fixtures used in the business or trade of Borrower which constitute personal property (but specifically

Borrower whether now or hereafter owned or existing, leased, consigned by or to, or acquired by, Borrower and wherever located; and (k) to the extent not otherwise included, all Proceeds of each of the foregoing and all accessions to,
substitutions and replacements for, and rents, profits and products of each of the foregoing, provided that Collateral does not include Intellectual Property, but does include any proceeds arising out of the disposition of Intellectual
Property. Notwithstanding the foregoing, Collateral shall not include any Equipment subject to a Lien described in clause (vi) of the definition of Permitted Liens, provided that (i) the financing documents in connection with such Lien
restrict Borrower from granting Lender a security interest in such Equipment, and (ii) such Equipment shall be deemed to be Collateral as soon as the applicable lender no longer has a Lien in such Equipment.

 REPRESENTATIONS AND WARRANTIES OF BORROWER

 Borrower represents, warrants and agrees that: 
 1.15 Corporate Status. Borrower is a corporation duly organized, legally existing and in good standing under the laws of the State of Delaware, and is duly qualified as a foreign corporation in all jurisdictions in which the nature

formation, tax identification number, organizational identification number and other information are correctly set forth in Exhibit C.

Liens. Borrower has the full power and authority to grant and convey to Lender a Lien in the Collateral as security for the Secured Obligations, free of all other Liens other than Permitted Liens. 
 1.17 Consents. Borrower’s execution, delivery and performance of the Notes, this Agreement and all other Loan Documents, and Borrower’s
execution of the Warrant, (i) have been duly authorized by all necessary corporate action of Borrower, (ii) will not result in the creation or imposition of any Lien upon the Collateral, other than Permitted Liens and the Liens created by

with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934. 








 1.19 Actions Before Governmental Authorities. Except as described on Schedule 5.5, there
are no actions, suits or proceedings at law or in equity or by or before any governmental authority now pending or, to the knowledge of Borrower, overtly threatened against or affecting Borrower or any business, property or rights of Borrower
(i) which involve any Loan Document or (ii) as to which there is a reasonable possibility of an adverse determination and which, if adversely determined, would reasonably be expected to, individually or in the aggregate, result in a
Material Adverse Effect. 
 1.20 Laws. Borrower is not in violation of any law, rule or regulation, or in default with respect to any
judgment, writ, injunction or decree of any governmental authority, where such violation or default is reasonably expected to result in a Material Adverse Effect. Borrower is not in default in any manner under any provision of any indenture or other
agreement, contract or instrument evidencing indebtedness, or any other material agreement, contract or instrument to which it is a party or by which it or any of its properties or assets are or may be bound and for which such default would
reasonably be expected to result in a Material Adverse Effect. 
 1.21 Information Correct. No information, report, Advance Request,
financial statement, exhibit or schedule furnished, by or on behalf of Borrower to Lender in connection with any Loan Document or included therein or delivered pursuant thereto contained, contains or will contain any material misstatement of fact or
omitted, omits or will omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were, are or will be made, not misleading. 
 1.22 Tax Matters. Except as described on Schedule 5.8, (a) Borrower has filed all federal, state and local tax returns that it is
required to file, (b) Borrower has duly paid or fully reserved for all taxes or installments thereof (including any interest or penalties) as and when due, which have or may become due pursuant to such returns, and (c) Borrower has paid or
fully reserved for any tax assessment received by Borrower for the three (3) years preceding the Closing Date, if any (including any taxes being contested in good faith and by appropriate proceedings). 
 1.23 Intellectual Property Claims. Borrower is the sole owner of, or otherwise has the right to use, the Intellectual Property. Except as
described on Schedule 5.9, each of the material Copyrights, Trademarks and Patents is valid and enforceable, and no part of the Intellectual Property that is owned by Borrower has been judged invalid or unenforceable, in whole or in part, and
no claim has been made to Borrower that any part of the Intellectual Property violates the rights of any third party except to the extent such claim would not reasonably be expected to cause a Material Adverse Effect. Exhibit D is a
true, correct and complete list of each of Borrower’s Patents, registered Trademarks, registered Copyrights, and material agreements under which Borrower licenses Intellectual Property from third parties (other than shrink-wrap software
licenses and other licenses which if terminated could not reasonably be expected to result in a Material Adverse Effect), together with application or registration numbers, as applicable, owned by Borrower or any Subsidiary. Borrower is not in
material breach of, nor has Borrower failed to perform any material obligations under, any of the foregoing contracts, licenses or agreements and, to Borrower’s knowledge, no third party to any such contract, license or agreement is in material
breach thereof or has failed to perform any material obligations thereunder.

with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934. 








 1.24 Intellectual Property. Except as described on Schedule 5.10 and to Borrower’s
knowledge, Borrower’s Intellectual Property constitutes all rights used in or necessary in the operation or conduct of Borrower’s business as currently conducted and proposed to be conducted by Borrower. Without limiting the generality of
the foregoing, Borrower has the right to freely transfer, license or assign Intellectual Property without condition, restriction or payment of any kind to any third party, and Borrower owns or has the right to use, pursuant to valid licenses, all
software development tools, library functions, compilers and all other third-party software and other items that are used in the design, development, promotion, sale, license, manufacture, import, export, use or distribution of Borrower Products.

 1.25 Borrower Products. Except as described on Schedule 5.11, no Intellectual Property owned by Borrower or Borrower Product
has been or is subject to any actual or, to the knowledge of Borrower, threatened litigation, proceeding (including any proceeding in the United States Patent and Trademark Office or any corresponding foreign office or agency) or outstanding decree,
order, judgment, settlement agreement or stipulation that restricts in any manner Borrower’s use, transfer or licensing thereof or that may affect the validity, use or enforceability thereof. There is no decree, order, judgment, agreement,
stipulation, arbitral award or other provision entered into in connection with any litigation or proceeding that obligates Borrower to grant licenses or ownership interest in any future Intellectual Property related to the operation or conduct of
the business of Borrower or Borrower Products. There is no outstanding or, to the knowledge of Borrower, threatened, dispute or disagreement of which Borrower is aware with respect to any contract, license or agreement between Borrower and any third
party related to the Intellectual Property. Borrower has not received any written notice or claim, or, to the knowledge of Borrower, oral notice or claim, challenging or questioning Borrower’s ownership in any Intellectual Property (or written
notice of any claim challenging or questioning the ownership in any licensed Intellectual Property of the owner thereof) or suggesting that any third party has any claim of legal or beneficial ownership with respect thereto nor, to Borrower’s
knowledge, is there a reasonable basis for any such claim. To Borrower’s knowledge, neither Borrower’s use of its Intellectual Property nor the production and sale of Borrower Products infringes the intellectual property or other rights of
others. 
 1.26 Financial Accounts. Schedule 5.12 and Exhibit E are a true, correct and complete list of (a) all
banks and other financial institutions at which Borrower or any Subsidiary maintains Deposit Accounts and (b) all institutions at which Borrower or any Subsidiary maintains an account holding Investment Property, and such exhibit correctly
identifies the name, address and telephone number of each bank or other institution, the name in which the account is held, a description of the purpose of the account, and the complete account number therefor. 
 1.27 Employee Loans. Other than travel advances made in the ordinary course of business, Borrower has no outstanding loans to any employee,
officer or director of the Borrower nor has Borrower guaranteed the payment of any loan made to an employee, officer or director of the Borrower by a third party.

 INSURANCE; INDEMNIFICATION 
 1.28 Coverage. So long as there are any Secured Obligations outstanding, Borrower shall cause to be carried and maintained commercial general liability insurance, on an occurrence form, against risks
customarily insured against in Borrower’s line of business. Such risks shall include the risks of bodily injury, including death, property damage, personal injury, advertising injury, and contractual liability per the terms of the
indemnification agreement found in Section 6.3. Borrower must maintain a minimum of Two Million Dollars ($2,000,000.00) of commercial general liability insurance for each occurrence. Borrower has and agrees to maintain a minimum of $5,000,000
of directors and officers’ insurance for each occurrence, and $10,000,000 in the aggregate. So long as there are any Secured Obligations outstanding, Borrower shall also cause to be carried and maintained insurance upon the Collateral that
constitutes tangible personal property, insuring against all risks of physical loss or damage howsoever caused, in an amount not less than the full replacement cost of the Collateral that constitutes tangible personal property. Borrower shall also
carry and maintain a fidelity insurance policy in an amount not less than $250,000. 
 1.29 Certificates. Borrower shall deliver to
Lender certificates of insurance that evidence Borrower’s compliance with its insurance obligations in Section 6.1 and the obligations contained in this Section 6.2. Borrower’s insurance certificate shall state Lender is an
additional insured for commercial general liability and fidelity insurance, and a loss payee for all risk property damage insurance, subject to the insurer’s approval, a loss payee for property insurance and additional insured for liability
insurance for any future insurance that Borrower may acquire from such insurer. Attached to the certificates of insurance will be additional insured endorsements for liability and lender’s loss payable endorsements for all risk property damage
insurance and fidelity. All certificates of insurance will provide for a minimum of thirty (30) days advance written notice to Lender of cancellation or any other change adverse to Lender’s interests. Any failure of Lender to scrutinize
such insurance certificates for compliance is not a waiver of any of Lender’s rights, all of which are reserved. 
 1.30
Indemnity. Borrower shall and does hereby indemnify and hold Lender, its officers, directors, employees, agents, in-house attorneys, representatives and shareholders harmless from and against any and all claims, costs, expenses, damages and
liabilities (including such claims, costs, expenses, damages and liabilities based on liability in tort, including strict liability in tort), including reasonable attorneys’ fees and disbursements and other costs of investigation or defense
(including those incurred upon any appeal), that may be instituted or asserted against or incurred by Lender or any such Person as the result of credit having been extended, suspended or terminated under this Agreement and the other Loan Documents
(other than the Warrant) or the administration of such credit, or in connection with or arising out of the transactions contemplated hereunder and thereunder, or any actions or failures to act in connection therewith, or arising out of the
disposition or utilization of the Collateral, excluding in all cases claims resulting solely from Lender’s gross negligence or willful misconduct. Borrower agrees to pay, and to save Lender harmless from, any and all liabilities with respect
to, or resulting from any delay in paying, any and all excise, sales or other similar taxes (excluding taxes imposed on or measured by the net income of Lender) that may be payable or determined to be payable with respect to any of the Collateral or
this Agreement.

Event of Default, Lender may, at any time or from time to time, apply, collect, liquidate, sell in one or more sales, lease or otherwise dispose of, any or all of the Collateral, in its then condition or following any commercially reasonable
preparation or processing, in such order as Lender may elect. Any such sale may be made either at public or private sale at its place of business or elsewhere. Borrower agrees that any such public or private sale may occur upon ten
(10) calendar days’ prior written notice to Borrower. Lender may require Borrower to assemble the Collateral and make it available to Lender at a place designated by Lender that is reasonably convenient to Lender and Borrower. The proceeds
of any sale, disposition or other realization upon all or any part of the Collateral shall be applied by Lender in the following order of priorities: 
 First, to Lender in an amount sufficient to pay in full Lender’s costs and professionals’ and advisors’ fees and expenses as described in Section 11.11; 
 Second, to Lender in an amount equal to the then unpaid amount of the Secured Obligations (including principal, interest, and the Default Rate
interest), in such order and priority as Lender may choose in its sole discretion; and

 Finally, after the full, final, and indefeasible payment in Cash of all of the Secured
Obligations, to any creditor holding a junior Lien on the Collateral, or to Borrower or its representatives or as a court of competent jurisdiction may direct. 
 Lender shall be deemed to have acted reasonably in the custody, preservation and disposition of any of the Collateral if it complies with the obligations of a secured party under the UCC. 
 1.57 No Waiver. Lender shall be under no obligation to marshal any of the Collateral for the benefit of Borrower or any other Person, and Borrower
expressly waives all rights, if any, to require Lender to marshal any Collateral. 
 1.58 Cumulative Remedies. The rights, powers and
remedies of Lender hereunder shall be in addition to all rights, powers and remedies given by statute or rule of law and are cumulative. The exercise of any one or more of the rights, powers and remedies provided herein shall not be construed as a
waiver of or election of remedies with respect to any other rights, powers and remedies of Lender. 
 1.59 Account Control Agreements.
Lender agrees that it will not send a “notice of exclusive control” under any Account Control Agreement unless an Event of Default has occurred and is continuing. 
 MISCELLANEOUS 
 1.60 Severability. Whenever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under such law, such provision shall be ineffective only to the extent and duration of such
prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

 or to such other address as each party may designate for itself by like notice. 
 1.62 Entire Agreement; Amendments. This Agreement, the Notes, and the other Loan Documents constitute the entire agreement and understanding of
the parties hereto in respect of the subject matter hereof and thereof, and supersede and replace in their entirety any prior proposals, term sheets, letters, negotiations or other documents or agreements, whether written or oral, with respect to
the subject matter hereof or thereof (including Lender’s revised proposal letter dated May 11, 2007). None of the terms of this Agreement, the Notes or any of the other Loan Documents may be amended except by an instrument executed by each
of the parties hereto. 
 1.63 No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of
this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any
party by virtue of the authorship of any provisions of this Agreement. 
 1.64 No Waiver. The powers conferred upon Lender by this
Agreement are solely to protect its rights hereunder and under the other Loan Documents and its interest in the Collateral and shall not impose any duty upon Lender to exercise any such powers. No omission or delay by Lender at any time to enforce
any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by Borrower at any time designated, shall be a waiver of any such right or remedy to which Lender is entitled, nor shall it in any way
affect the right of Lender to enforce such provisions thereafter. 
 1.65 Survival. All agreements, representations and warranties
contained in this Agreement, the Notes and the other Loan Documents or in any document delivered pursuant hereto or thereto shall be for the benefit of Lender and shall survive the execution and delivery of this Agreement and the expiration or other
termination of this Agreement.

 Portions of this Exhibit were omitted, as indicated by [****], and have been filed separately
with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934. 








 1.66 Successors and Assigns. The provisions of this Agreement and the other Loan Documents shall
inure to the benefit of and be binding on Borrower and its permitted assigns (if any). Borrower shall not assign its obligations under this Agreement, the Notes or any of the other Loan Documents without Lender’s express prior written consent,
and any such attempted assignment shall be void and of no effect. Lender may assign, transfer, or endorse its rights hereunder and under the other Loan Documents (other than the Warrant) without prior notice to Borrower, and all of such rights shall
inure to the benefit of Lender’s successors and assigns. 
 1.67 Governing Law. This Agreement, the Notes and the other Loan
Documents have been negotiated and delivered to Lender in the Commonwealth of Massachusetts, and shall have been accepted by Lender in the Commonwealth of Massachusetts. Payment to Lender by Borrower of the Secured Obligations is due in the
Commonwealth of Massachusetts. This Agreement, the Notes and the other Loan Documents shall be governed by, and construed and enforced in accordance with, the laws of the Commonwealth of Massachusetts, excluding conflict of laws principles that
would cause the application of laws of any other jurisdiction. 
 1.68 Consent to Jurisdiction and Venue. All judicial proceedings (to
the extent that the reference requirement of Section 11.10 is not applicable) arising in or under or related to this Agreement, the Notes or any of the other Loan Documents may be brought in any state or federal court located in the
Commonwealth of Massachusetts. By execution and delivery of this Agreement, each party hereto generally and unconditionally: (a) consents to nonexclusive personal jurisdiction in Suffolk County, Commonwealth of Massachusetts; (b) waives
any objection as to jurisdiction or venue in Suffolk County, Commonwealth of Massachusetts; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any
judgment rendered thereby in connection with this Agreement, the Notes or the other Loan Documents. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the
requirements for notice set forth in Section 11.2, and shall be deemed effective and received as set forth in Section 11.2. Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the
right of either party to bring proceedings in the courts of any other jurisdiction. 
 1.69 Mutual Waiver of Jury Trial / Judicial Reference.

 (a) Because disputes arising in connection with complex financial transactions are most quickly and economically resolved
by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF BORROWER AND
LENDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY BORROWER AGAINST LENDER OR ITS ASSIGNEE
OR BY LENDER OR ITS ASSIGNEE AGAINST BORROWER. This waiver extends to all such Claims, including Claims that involve Persons other than Borrower and Lender; Claims that arise out of or are in any way connected to the relationship between Borrower
and Lender; and any Claims for damages, breach of contract, tort, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement, any other Loan Document.

 Portions of this Exhibit were omitted, as indicated by [****], and have been filed separately
with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934. 








 (b) In the event Claims are to be resolved by judicial reference, either party may seek
from a court identified in Section 11.9, any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to
resolution by judicial reference. 
 1.70 Professional Fees. Borrower promises to pay Lender’s fees and expenses necessary to
finalize the loan documentation, including but not limited to reasonable attorneys fees, UCC searches, filing costs, and other miscellaneous expenses. In addition, Borrower promises to pay any and all reasonable attorneys’ and other
professionals’ fees and expenses incurred by Lender after the Closing Date in connection with or related to: (a) the Loan; (b) the administration, collection, or enforcement of the Loan; (c) the amendment or modification of the
Loan Documents; (d) any waiver, consent, release, or termination under the Loan Documents; (e) the protection, preservation, sale, lease, liquidation, or disposition of Collateral or the exercise of remedies with respect to the Collateral;
(f) any legal, litigation, administrative, arbitration, or out of court proceeding in connection with or related to Borrower or the Collateral, and any appeal or review thereof; and (g) any bankruptcy, restructuring, reorganization,
assignment for the benefit of creditors, workout, foreclosure, or other action related to Borrower, the Collateral, the Loan Documents, including representing Lender in any adversary proceeding or contested matter commenced or continued by or on
behalf of Borrower’s estate, and any appeal or review thereof. 
 1.71 Confidentiality. Lender acknowledges that certain items of
Collateral and information provided to Lender by Borrower are confidential and proprietary information of Borrower, if and to the extent such information is marked as confidential by Borrower at the time of disclosure or if the information is of a
nature that would reasonably be considered confidential (the “Confidential Information”). Accordingly, Lender agrees that any Confidential Information it may obtain in the course of acquiring, administering, or perfecting Lender’s
security interest in the Collateral shall not be disclosed to any other person or entity in any manner whatsoever, in whole or in part, without the prior written consent of Borrower, except that Lender may disclose any such information: (a) to
its own directors, officers, employees, accountants, counsel and other professional advisors and to its affiliates if Lender in its sole discretion determines that any such party should have access to such information in connection with such
party’s responsibilities in connection with the Loan or this Agreement and, provided that such recipient of such Confidential Information either (i) agrees to be bound by the confidentiality provisions of this paragraph or (ii) is
otherwise subject to confidentiality restrictions that reasonably protect against the disclosure of Confidential Information; (b) if such information is generally available to the public; (c) if required or appropriate in any report,
statement or testimony submitted to any governmental authority having or claiming to have jurisdiction over Lender; (d) if required or appropriate in response to any summons or subpoena or in connection with any litigation, to the extent
permitted or deemed advisable by Lender’s counsel; (e) to comply with any legal requirement or law applicable to Lender; (f) to the extent reasonably necessary in connection with the exercise of any right or remedy under any Loan
Document, including Lender’s sale, lease, or other disposition of Collateral after default; (g) to any participant or assignee of Lender 

  

 24 
  


 Portions of this Exhibit were omitted, as indicated by [****], and have been filed separately

or any prospective participant or assignee; provided, that such participant or assignee or prospective participant or assignee agrees in writing to be
bound by this Section prior to disclosure; or (h) otherwise with the prior consent of Borrower; provided, that any disclosure made in violation of this Agreement shall not affect the obligations of Borrower or any of its affiliates or
any guarantor under this Agreement or the other Loan Documents. 
 1.72 Assignment of Rights. Borrower acknowledges and understands
that Lender may sell and assign all or part of its interest hereunder and under the Note(s) and Loan Documents to any person or entity (an “Assignee”). Lender agrees to provide Borrower prompt notice after any such sale or assignment
(provided, however, such notice need not be given for any partial sale or assignment of Lender’s interest hereunder). After such assignment the term “Lender” as used in the Loan Documents shall mean and include such Assignee, and such
Assignee shall be vested with all rights, powers and remedies of Lender hereunder with respect to the interest so assigned; but with respect to any such interest not so transferred, Lender shall retain all rights, powers and remedies hereby given.
No such assignment by Lender shall relieve Borrower of any of its obligations hereunder. Lender agrees that in the event of any transfer by it of the Note(s), it will endorse thereon a notation as to the portion of the principal of the Note(s),
which shall have been paid at the time of such transfer and as to the date to which interest shall have been last paid thereon. 
 1.73
Revival of Secured Obligations. This Agreement and the Loan Documents shall remain in full force and effect and continue to be effective if any petition is filed by or against Borrower for liquidation or reorganization, if Borrower becomes
insolvent or makes an assignment for the benefit of creditors, if a receiver or trustee is appointed for all or any significant part of Borrower’s assets, or if any payment or transfer of Collateral is recovered from Lender. The Loan Documents
and the Secured Obligations and Collateral security shall continue to be effective, or shall be revived or reinstated, as the case may be, if at any time payment and performance of the Secured Obligations or any transfer of Collateral to Lender, or
any part thereof is rescinded, avoided or avoidable, reduced in amount, or must otherwise be restored or returned by, or is recovered from, Lender or by any obligee of the Secured Obligations, whether as a “voidable preference,”
“fraudulent conveyance,” or otherwise, all as though such payment, performance, or transfer of Collateral had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, avoided, avoidable, restored, returned,
or recovered, the Loan Documents and the Secured Obligations shall be deemed, without any further action or documentation, to have been revived and reinstated except to the extent of the full, final, and indefeasible payment to Lender in Cash.

 1.74 Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of
counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument. 
 1.75 No Third Party Beneficiaries. No provisions of the Loan Documents are intended, nor will be interpreted, to provide or create any third-party
beneficiary rights or any other rights of any kind in any person other than Lender and Borrower unless specifically provided otherwise herein, and, except as otherwise so provided, all provisions of the Loan Documents will be personal and solely
between the Lender and the Borrower.

with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934. 








 1.76 Specific Performance. The parties hereto hereby declare that it is impossible to measure in
money the damages which will accrue to Lender by reason of Borrower’s failure to perform any of the obligations under this Agreement and agree that the terms of this Agreement shall be specifically enforceable by Lender. If Lender institutes
any action or proceeding to specifically enforce the provisions hereof, any Person against whom such action or proceeding is brought hereby waives the claim or defense therein that Lender has an adequate remedy at law, and such Person shall not
offer in any such action or proceeding the claim or defense that such remedy at law exists. 
 1.77 Publicity. Lender may use
Borrower’s name and logo, and include a brief description of the relationship between Borrower and Lender, in Lender’s marketing materials, upon prior written approval of Borrower, which approval shall not be unreasonably withheld.

 1.78 Termination. Upon satisfaction in full of the Secured Obligations (other than inchoate indemnity obligations), and provided
that no other extensions of credit are anticipated or may be provided hereunder, this Agreement shall be deemed terminated.

 ADDENDUM 1 to LOAN AND SECURITY AGREEMENT 
 (a) Borrower’s Business. For purposes of this Addendum 1, Borrower shall be deemed to include its “affiliates”
as defined in Title 13 Code of Federal Regulations Section 121.103. Borrower represents and warrants to Lender (as of the Closing Date and for a period of one year thereafter) and covenants to Lender as follows: 
  

	 	(1)	Size Status. Borrower does not have more than 750 employees or average net income after Federal income taxes (excluding any carry-over losses) for the preceding two completed
fiscal years in excess of $6 million; 

  

	 	(2)	No Relender. Borrower’s primary business activity does not involve, directly or indirectly, providing funds to others, purchasing debt obligations, factoring, or long-term
leasing of equipment with no provision for maintenance or repair; 

  

	 	(3)	No Passive Business. Borrower is engaged in a regular and continuous business operation (excluding the mere receipt of payments such as dividends, rents, lease payments, or
royalties). Borrower’s employees are managing the majority of day to day operations, and Borrower is not an “investment company” under the Investment Company Act of 1940. Borrower will not pass through substantially all of the
proceeds of the Loan to another entity; 

  

	 	(4)	No Real Estate Business. Borrower is not classified under Major Group 65 (Real Estate) or Industry No. 1531 (Operative Builders) of the SIC Manual. The proceeds of the
Loan will not be used to acquire or refinance real estate unless Borrower (x) is acquiring an existing property and will use at least 51 percent of the usable square footage for its business purposes; (y) is building or renovating a
building and will use at least 67 percent of the usable square footage for its business purposes; or (z) occupies the subject property and uses at least 67 percent of the usable square footage for its business purposes.


  

	 	(5)	No Project Finance. Borrower’s assets (other than the equipment used in Borrower’s business) are not intended to be reduced or consumed, generally without replacement, as
the life of its business progresses, and the nature of Borrower’s business does not require that a stream of cash payments be made to the business’s financing sources, on a basis associated with the continuing sale of assets (e.g., real
estate development projects and oil and gas wells). The primary purpose of the Loan is not to fund production of a single item or defined limited number of items, generally over a defined production period, where such production will constitute
the majority of the activities of Borrower (e.g., motion pictures and electric generating plants). 

  

 40 









	 	(6)	No Farm Land Purchases. Borrower will not use the proceeds of the Loan to acquire farm land which is or is intended to be used for agricultural or forestry purposes, such as the
production of food, fiber, or wood, or is so taxed or zoned. 

  

	 	(7)	No Foreign Investment. The proceeds of the Loan will not be used substantially for a foreign subsidiary. At the time of the Loan, Borrower will not have more than 49
percent of its employees or tangible assets located outside the United States. The representation in this subsection (7) is made only as of the date hereof and shall not continue for one year as contemplated in the first sentence of this
Section 1. 

 (b) Small Business Administration Documentation. Lender acknowledges that
Borrower completed, executed and delivered to Lender SBA Forms 480, 652 and 1031 (Parts A and B) together with a business plan showing Borrower’s financial projections (including balance sheets and income and cash flows statements) for the
period described therein and a written statement (whether included in the purchase agreement or pursuant to a separate statement) from Lender regarding its intended use of proceeds from the sale of securities to Lender (the “Use of Proceeds
Statement”). Borrower represents and warrants to Lender that the information regarding Borrower and its affiliates set forth in the SBA Form 480, Form 652 and Form 1031 and the Use of Proceeds Statement delivered as of the
Closing Date is accurate and complete. 
 (c) Inspection. The following covenants contained in this Section
(c) are intended to supplement and not to restrict the related provisions of the Loan Documents. Subject to the preceding sentence, Borrower will permit, for so long as Lender holds any debt or equity securities of Borrower, Lender or
its representative, at Lender’ expense, and examiners of the SBA to visit and inspect the properties and assets of Borrower, to examine its books of account and records, and to discuss Borrower’s affairs, finances and accounts with
Borrower’s officers, senior management and accountants, all at such reasonable times as may be requested by Lender or the SBA. 
 (d) Annual Assessment. Promptly after the end of each calendar year (but in any event prior to February 28 of each year) and at such other times as may be reasonably requested by Lender, Borrower will deliver to Lender a
written assessment of the economic impact of Lender’ investment in Borrower, specifying the full-time equivalent jobs created or retained in connection with the investment, the impact of the investment on the businesses of Borrower in terms of
expanded revenue and taxes, other economic benefits resulting from the investment (such as technology development or commercialization, minority business development, or expansion of exports) and such other information as may be required regarding
Borrower in connection with the filing of Lender’s SBA Form 468. Lender will assist Borrower with preparing such assessment. In addition to any other rights granted hereunder, Borrower will grant Lender and the SBA access to
Borrower’s books and records for the purpose of verifying the use of such proceeds. Borrower also will furnish or cause to be furnished to Lender such other information regarding the business, affairs and condition of Borrower as Lender
may from time to time reasonably request. 
 (e) Use of Proceeds. Borrower will use the proceeds from the Loan
only for general working capital and corporate purposes. Borrower will deliver to Lender from 

  

 41 








 
time to time promptly following Lender’s request, a written report, certified as correct by Borrower’s Chief Financial Officer, verifying the
purposes and amounts for which proceeds from the Loan have been disbursed. Borrower will supply to Lender such additional information and documents as Lender reasonably requests with respect to its use of proceeds and will permit Lender and the
SBA to have access to any and all Borrower records and information and personnel as Lender deems necessary to verify how such proceeds have been or are being used, and to assure that the proceeds have been used for the purposes specified in this
Section 7.16. 
 (f) Activities and Proceeds. Neither Borrower nor any of its affiliates (if any) will engage in
any activities or use directly or indirectly the proceeds from the Loan for any purpose for which a small business investment company is prohibited from providing funds by the SBIC Act, including 13 C.F.R. §107.720. Without obtaining
the prior written approval of Lender, Borrower will not change within 1 year of the date hereof, Borrower’s current business activity to a business activity which a licensee under the SBIC Act is prohibited from providing funds by the SBIC Act.

 (g) Compliance and Resolution. Borrower agrees that a failure to comply with Borrower’s obligations under
this Addendum, or any other set of facts or circumstances where it has been asserted by any governmental regulatory agency (or Lender believes that there is a substantial risk of such assertion) that Lender and its affiliates are not entitled to
hold, or exercise any significant right with respect to, any securities issued to Lender by Borrower, will constitute a breach of the obligations of Borrower under the financing agreements between Borrower and Lender. In the event of (i) a
failure to comply with Borrower’s obligations under this Addendum; or (ii) an assertion by any governmental regulatory agency (or Lender believes that there is a substantial risk of such assertion) of a failure to comply with
Borrower’s obligations under this Addendum, then (i) Lender and Borrower will meet and resolve any such issue in good faith to the satisfaction of Borrower, Lender, and any governmental regulatory agency, and (ii) upon request of
Lender, Borrower will cooperate and assist with any assignment of the financing agreements from Hercules Technology II, L.P. to Hercules Technology Growth Capital, Inc. 
 (h) Cost of Money. Notwithstanding any provision to the contrary contained in the Loan Documents, Lender hereby agrees that all
interest and fees charged pursuant to the Loan Documents shall comply with the provisions of 13 C.F.R. § 107.855, including, without limitation, that such amounts shall not exceed the Cost of Money ceiling. The current Cost of Money ceiling for
the investment by Hercules Technology II, L.P. in Borrower is fourteen percent.
