within ten (10) days after the date such payment is due, Borrower shall pay Bank a late fee equal to the lesser of (i) five percent (5%) of the amount of such unpaid amount or (ii) the maximum amount permitted to be charged under
applicable law. All Obligations shall bear interest, from and after the occurrence and during the continuance of an Event of Default, at a rate equal to five (5) percentage points above the interest rate applicable immediately prior to the
occurrence of the Event of Default; provided, however, the foregoing shall not apply with respect to any payment that is not made as a result of Banks failure withdraw payments as provided in Section 2.3(c).

its option, charge such interest, all Bank Expenses, and all Periodic Payments against any of Borrowers deposit accounts or against the Revolving Line, in which case those amounts shall thereafter accrue interest at the rate then applicable
hereunder. Any interest not paid when due shall be compounded by becoming a part of the Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder. Bank shall provide Borrower notice of any charge under
this provision that is not charged against the Designated Deposit Account.

(d) Computation. In the event the Prime
Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased, effective as of the day the Prime Rate is changed, by an amount equal to such change in the Prime Rate. All interest chargeable

2.4 Crediting Payments. Prior to the occurrence of an Event of Default, Bank shall credit a wire transfer of funds, check or other item of payment to such deposit account or Obligation as Borrower
specifies. After the occurrence of an Event of Default, Bank shall have the right, in its sole discretion, to immediately apply any wire transfer of funds, check, or other item of payment to conditionally reduce Obligations, but such applications of
funds shall not be considered a payment on account unless such payment is of immediately available federal funds or unless and until such check or other item of payment is honored when presented for payment. Notwithstanding anything to the contrary
contained herein, any wire transfer or payment received by Bank after 12:00 noon Pacific time shall be deemed to have been received by Bank as of the opening of business on the immediately following Business Day. Whenever any payment to Bank under
the Loan Documents would otherwise be due (except by reason of acceleration) on a date that is not a Business Day, such payment shall instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be
payable for the period of such extension.

4.1 Grant of Security Interest. Borrower grants and pledges to Bank a continuing security interest in the Collateral to secure prompt repayment of any and all Obligations and in order to secure
prompt performance by Borrower of each of its covenants and duties under the Loan Documents. Except as set forth in the Schedule, such security interest constitutes a valid, first priority security interest in the presently existing Collateral, and
will constitute a valid, first priority security interest in later-acquired Collateral. Borrower also hereby agrees to not sell, transfer, assign, mortgage, pledge, lease, grant a security interest in, or encumber any of its intellectual property.
Notwithstanding any termination, Banks Lien on the Collateral shall remain in effect for so long as any Obligations are outstanding.

4.2 Perfection of Security Interest. Borrower authorizes Bank to file at any time financing statements, continuation statements, and amendments thereto that (i) either specifically describe
the Collateral or describe the Collateral as all assets of Borrower of the kind pledged hereunder, and (ii) contain any other information required by the Code for the sufficiency of filing office acceptance of any financing statement,
continuation statement, or amendment, including whether Borrower is an organization, the type of organization and any organizational identification number issued to Borrower, if applicable. Any such financing statements may be signed by Bank on
behalf of Borrower, as provided in the Code, and may be filed at any time in any jurisdiction whether or not Revised Article 9 of the Code is then in effect in that jurisdiction. Borrower shall from time to time endorse and deliver to Bank, at
the request of Bank, all Negotiable Collateral and other documents that Bank may reasonably request, in form satisfactory to Bank, to perfect and continue perfected Banks security interests in the Collateral and in order to fully consummate
all of the transactions contemplated under the Loan Documents. Borrower shall have possession of the Collateral, except where expressly otherwise provided in this Agreement or where Bank chooses to perfect its security interest by possession in
addition to the filing of a financing statement. Where Collateral is in possession of a third party bailee, Borrower shall take such steps as Bank reasonably requests for Bank to (i) obtain an acknowledgment, in form and substance satisfactory
to Bank, of the bailee that the bailee holds such Collateral for the benefit of Bank, (ii) obtain control of any Collateral consisting of investment property, deposit accounts, letter-of-credit rights or electronic chattel paper (as
such items and the term control are defined in Revised Article 9 of the Code) by causing the securities intermediary or depositary institution or issuing bank to execute a control agreement in form and substance satisfactory to
Bank. Borrower will not create any chattel paper without placing a legend on the chattel paper acceptable to Bank indicating that Bank has a security interest in the chattel paper. Borrower from time to time may deposit with Bank specific cash
collateral to secure specific Obligations; Borrower authorizes Bank to hold such specific balances in pledge and to decline to honor any drafts thereon or any request by Borrower or any other Person to pay or otherwise transfer any part of such
balances for so long as the specific Obligations are outstanding.

copies thereof and to check, test, and appraise the Collateral in order to verify Borrowers financial condition or the amount, condition of, or any other matter relating to, the Collateral.

its intellectual property has been judged invalid or unenforceable, in whole or in part, and no claim has been made to Borrower that any part of its intellectual property violates the rights of any third party except to the extent such claim could

9.1 Rights and Remedies. Upon
the occurrence and during the continuance of an Event of Default, Bank may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower:

(a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in Section 8.6, all Obligations shall become immediately due and payable without any action by Bank);

(b) Cease advancing money or extending credit to or for the benefit of Borrower under this Agreement or under any other agreement
between Borrower and Bank;

(c) Settle or adjust disputes and claims directly with account debtors for amounts, upon terms
and in whatever order that Bank reasonably considers advisable;

(d) Make such payments and do such acts as Bank considers
necessary or reasonable to protect its security interest in the Collateral. Borrower agrees to assemble the Collateral if Bank so requires, and to make the Collateral available to Bank as Bank may designate. Borrower authorizes Bank to enter the
premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in Banks determination appears to be prior or
superior to its security interest and to pay all expenses incurred in connection therewith. With respect to any of Borrowers owned premises, Borrower hereby grants Bank a license to enter into possession of such premises and to occupy the
same, without charge, in order to exercise any of Banks rights or remedies provided herein, at law, in equity, or otherwise;



- 18 -



---

(e) Set off and apply to the Obligations any and all (i) balances and deposits of
Borrower held by Bank, and (ii) indebtedness at any time owing to or for the credit or the account of Borrower held by Bank;

(f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral. Bank is hereby granted a license or other
right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrowers labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Banks exercise of its rights under this Section 9.1, Borrowers
rights under all licenses and all franchise agreements shall inure to Banks benefit;

(g) Sell the Collateral at either
a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrowers premises) as Bank determines is commercially reasonable, and apply any proceeds to
the Obligations in whatever manner or order Bank deems appropriate. Bank may sell the Collateral without giving any warranties as to the Collateral. Bank may specifically disclaim any warranties of title or the like. This procedure will not be
considered adversely to affect the commercial reasonableness of any sale of the Collateral. If Bank sells any of the Collateral upon credit, Borrower will be credited only with payments actually made by the purchaser, received by Bank, and applied
to the indebtedness of the purchaser. If the purchaser fails to pay for the Collateral, Bank may resell the Collateral and Borrower shall be credited with the proceeds of the sale;

(h) Bank may credit bid and purchase at any public sale;

(i) Apply for the appointment of a receiver, trustee, liquidator or conservator of the Collateral, without notice and without regard to the adequacy of the security for the Obligations and without regard
to the solvency of Borrower, any guarantor or any other Person liable for any of the Obligations; and

(j) Any deficiency
that exists after disposition of the Collateral as provided above will be paid immediately by Borrower.

Bank may comply with any applicable
state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.

9.2 Power of Attorney. Effective only upon the occurrence and during the continuance of an Event of Default, Borrower hereby
irrevocably appoints Bank (and any of Banks designated officers, or employees) as Borrowers true and lawful attorney to: (a) send requests for verification of Accounts or notify account debtors of Banks security interest in
the Accounts; (b) endorse Borrowers name on any checks or other forms of payment or security that may come into Banks possession; (c) sign Borrowers name on any invoice or bill of lading relating to any Account, drafts
against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all claims under and decisions with respect to
Borrowers policies of insurance; (f) settle and adjust disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; and (g) to file, in its sole
discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral without the signature of Borrower where permitted by law; provided Bank may exercise such power of attorney to sign the name of
Borrower on any of the documents described in clause (g) above, regardless of whether an Event of Default has occurred. The appointment of Bank as Borrowers attorney in fact, and each and every one of Banks rights and powers, being
coupled with an interest, is irrevocable until all of the Obligations have been fully repaid and performed and Banks obligation to provide Credit Extensions hereunder is terminated.

9.3 Accounts Collection. At any time after the occurrence and during the continuance
of an Event of Default, Bank may notify any Person owing funds to Borrower of Banks security interest in such funds and verify the amount of such Account. Borrower shall collect all amounts owing to Borrower for Bank, receive in trust all
payments as Banks trustee, and immediately deliver such payments to Bank in their original form as received from the account debtor, with proper endorsements for deposit.

9.4 Bank Expenses. If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities,
as required under the terms of this Agreement, then Bank may do any or all of the following after reasonable notice to Borrower: (a) make payment of the same or any part thereof; (b) set up such reserves under the Revolving Line as Bank
deems necessary to protect Bank from the exposure created by such failure; or (c) obtain and maintain insurance policies of the type discussed in Section 6.5 of this Agreement, and take any action with respect to such policies as Bank
deems prudent. Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and payable, and shall bear interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral. Any
payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank of any Event of Default under this Agreement.

9.5 Banks Liability for Collateral. Bank has no obligation to clean up or otherwise prepare the Collateral for sale. All risk of loss, damage or destruction of the Collateral shall be borne
by Borrower.

9.6 No Obligation to Pursue Others. Bank has no obligation to attempt to satisfy the Obligations by
collecting them from any other Person liable for them and Bank may release, modify or waive any collateral provided by any other Person to secure any of the Obligations, all without affecting Banks rights against Borrower. Borrower waives any
right it may have to require Bank to pursue any other Person for any of the Obligations.

9.7 Remedies Cumulative.
Banks rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No
exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrowers part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by
it. No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given. Borrower expressly agrees that this
Section may not be waived or modified by Bank by course of performance, conduct, estoppel or otherwise.

9.8 Demand;
Protest. Except as otherwise provided in this Agreement, Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment and any other notices relating to the Obligations.

10. NOTICES.

Unless otherwise provided in this Agreement, all notices or demands by any party relating to this Agreement or any other agreement entered into in connection herewith shall be in writing and (except for
financial statements and other informational documents which may be sent by first-class mail, postage prepaid) shall be personally delivered or sent by a recognized overnight delivery service, certified mail, postage prepaid, return receipt
requested, or by telefacsimile to Borrower or to Bank, as the case may be, at its addresses set forth below:

11. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER.

This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of California, without
regard to principles of conflicts of law. Each of Borrower and Bank hereby submits to the exclusive jurisdiction of the state and Federal courts located in the State of California. THE UNDERSIGNED ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER CHOICE, KNOWINGLY AND VOLUNTARILY, AND
FOR THE MUTUAL BENEFIT OF ALL PARTIES, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OTHER DOCUMENT, INSTRUMENT OR AGREEMENT BETWEEN THE UNDERSIGNED PARTIES.

12. REFERENCE PROVISION.

In the event the Jury Trial Waiver set forth above is not enforceable, the parties elect to proceed under this Judicial Reference Provision.

12.1 Mechanics.

(a) With the exception of the items specified in clause (b), below, any controversy, dispute or claim (each, a Claim) between the parties arising out of or relating to this Agreement or any
other document, instrument or agreement between the undersigned parties (collectively in this Section, the Comerica Documents), will be resolved by a reference proceeding in California in accordance with the provisions of Sections 638 et
seq. of the California Code of Civil Procedure (CCP), or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as
otherwise provided in the Comerica Documents, venue for the reference proceeding will be in the state or federal court in the county or district where the real property involved in the action, if any, is located or in the state or federal court in
the county or district where venue is otherwise appropriate under applicable law (the Court).

(b) The matters
that shall not be subject to a reference are the following: (i) foreclosure of any security interests in real or personal property, (ii) exercise of self-help remedies (including, without limitation, set-off), (iii) appointment of a
receiver and (iv) temporary, provisional or ancillary remedies (including, without limitation, writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). This reference provision does not limit the right
of any party to exercise or oppose any of the rights and remedies described in clauses (i) and (ii) or to seek or oppose from a court of competent jurisdiction any of the items described in clauses (iii) and (iv). The exercise of, or
opposition to, any of those items does not waive the right of any party to a reference pursuant to this reference provision as provided herein.

---

(c) The referee shall be a retired judge or justice selected by mutual written agreement of
the parties. If the parties do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by the Presiding Judge of the Court (or his or her representative). A
request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted. Pursuant to CCP § 170.6, each party shall have one peremptory
challenge to the referee selected by the Presiding Judge of the Court (or his or her representative).

(d) The parties agree
that time is of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested, subject to change in the time periods specified herein for good cause shown, to (i) set the matter for a status and trial-setting
conference within fifteen (15) days after the date of selection of the referee, (ii) if practicable, try all issues of law or fact within one hundred twenty (120) days after the date of the conference and (iii) report a statement
of decision within twenty (20) days after the matter has been submitted for decision.

(e) The referee will have power
to expand or limit the amount and duration of discovery. The referee may set or extend discovery deadlines or cutoffs for good cause, including a partys failure to provide requested discovery for any reason whatsoever. Unless otherwise ordered
based upon good cause shown, no party shall be entitled to priority in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen
(15) days after service. All disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding.

12.2 Procedures. Except as expressly set forth herein, the referee shall determine the manner in which the reference proceeding is
conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding. All proceedings and hearings conducted before the referee, except
for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee, and the referee will be provided a courtesy copy of the transcript. The party
making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referees power to award costs to the prevailing party, the parties will equally share the cost of the referee and the court reporter at
trial.

12.3 Application of Law. The referee shall be required to determine all issues in accordance with existing case
law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable as well as
legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall
issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference. Pursuant to CCP § 644, such decision shall be entered by the Court as a judgment or an order in the
same manner as if the action had been tried by the Court and any such decision will be final, binding and conclusive. The parties reserve the right to appeal from the final judgment or order or from any appealable decision or order entered by the
referee. The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference proceeding under
this provision.

12.4 Repeal. If the enabling legislation which provides for appointment of a referee is repealed (and
no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration. The arbitration will be conducted by a retired judge or justice, in
accordance with the California Arbitration Act §1280 through §1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such arbitration proceeding.

12.5 THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES, DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED
BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS REFERENCE
PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE OTHER COMERICA DOCUMENTS.

13. GENERAL PROVISIONS.

13.1 Successors and Assigns. This Agreement shall bind and inure to the benefit of the respective successors and permitted assigns
of each of the parties and shall bind all Persons who become bound as a debtor to this Agreement; provided, however, that neither this Agreement nor any rights hereunder may be assigned by Borrower without Banks prior written consent, which
consent may be granted or withheld in Banks sole discretion. Bank shall have the right without the consent of or notice to Borrower to sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Banks
obligations, rights and benefits hereunder.

13.2 Indemnification. Borrower shall defend, indemnify and hold harmless
Bank and its officers, employees, and agents against: (a) all obligations, demands, claims, and liabilities claimed or asserted by any other party in connection with the transactions contemplated by this Agreement; and (b) all losses or
Bank Expenses in any way suffered, incurred, or paid by Bank, its officers, employees and agents as a result of or in any way arising out of, following, or consequential to transactions between Bank and Borrower whether under this Agreement, or
otherwise (including without limitation reasonable attorneys fees and expenses), except for losses caused by Banks gross negligence or willful misconduct.

13.3 Time of Essence. Time is of the essence for the performance of all obligations set forth in this Agreement.

13.4 Severability of Provisions. Each provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal enforceability of any
specific provision.

13.5 Amendments in Writing, Integration. All amendments to or terminations of this Agreement or
the other Loan Documents must be in writing. All prior agreements, understandings, representations, warranties, and negotiations between the parties hereto with respect to the subject matter of this Agreement and the other Loan Documents, if any,
are merged into this Agreement and the Loan Documents.

13.6 Counterparts. This Agreement may be executed in any number
of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement.

13.7 Survival. All covenants, representations and warranties made in this Agreement shall continue in full force and effect so
long as any Obligations remain outstanding or Bank has any obligation to make any Credit Extension to Borrower. The obligations of Borrower to indemnify Bank with respect to the expenses, damages, losses, costs and liabilities described in
Section 13.2 shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Bank have run.

COLLATERAL DESCRIPTION ATTACHMENT

TO LOAN AND SECURITY AGREEMENT

All personal property of Borrower (herein
referred to as Borrower or Debtor) whether presently existing or hereafter created or acquired, and wherever located, including, but not limited to:

(a) all accounts (including health-care-insurance receivables), chattel paper (including tangible and electronic chattel paper), deposit accounts, documents (including negotiable documents), equipment
(including all accessions and additions thereto), general intangibles (including payment intangibles and software), goods (including fixtures), instruments (including promissory notes), inventory (including all goods held for sale or lease or to be
furnished under a contract of service, and including returns and repossessions), investment property (including securities and securities entitlements), letter of credit rights, money, and all of Debtors books and records with respect to any
of the foregoing, and the computers and equipment containing said books and records; and

(b) any and all cash proceeds and/or
noncash proceeds of any of the foregoing, including, without limitation, insurance proceeds, and all supporting obligations and the security therefor or for any right to payment. All terms above have the meanings given to them in the California
Uniform Commercial Code, as amended or supplemented from time to time, including revised Division 9 of the Uniform Commercial Code-Secured Transactions, added by Stats. 1999, c.991 (S.B. 45), Section 35, operative July 1, 2001.

Notwithstanding the foregoing, the Collateral shall not include (i) any of the ATEL Equipment (as such term is defined in that
certain Loan and Security Agreement by and between Debtor and Comerica Bank dated as of November , 2010 or (ii) any copyrights, patents, trademarks, servicemarks and applications therefor, now owned or hereafter
acquired, or any claims for damages by way of any past, present and future infringement of any of the foregoing (collectively, the Intellectual Property); provided, however, that the Collateral shall include all accounts and general
intangibles that consist of rights to payment and proceeds from the sale, licensing or disposition of all or any part, or rights in, the foregoing (the Rights to Payment). Notwithstanding the foregoing, if a judicial authority (including
a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property is necessary to have a security interest in the Rights to Payment, then the Collateral shall automatically, and effective as of
November , 2010, include the Intellectual Property to the extent necessary to permit perfection of Banks security interest in the Rights to Payment.

I may obtain the required insurance from any company that is acceptable to the Bank, and will deliver proof of such coverage with an effective date of November , 2010 or
earlier.

I understand and agree that if I fail to deliver proof of insurance to the Bank at the address below, or upon the lapse or
cancellation of such insurance, the Bank may procure Lenders Single Interest Insurance or other similar coverage on the property. If the Bank procures insurance to protect its interest in the property described in the security documents, the
cost for the insurance will be added to my indebtedness as provided in the security documents. Lenders Single Interest Insurance shall cover only the Banks interest as a secured party, and shall become effective at the earlier of the
funding date of this transaction or the date my insurance was canceled or expired. I UNDERSTAND THAT LENDERS SINGLE INTEREST INSURANCE WILL PROVIDE ME WITH ONLY LIMITED PROTECTION AGAINST PHYSICAL DAMAGE TO THE COLLATERAL, UP TO THE BALANCE OF
THE LOAN, HOWEVER, MY EQUITY IN THE PROPERTY WILL NOT BE INSURED. FURTHER, THE INSURANCE WILL NOT PROVIDE MINIMUM PUBLIC LIABILITY OR PROPERTY DAMAGE INDEMNIFICATION AND DOES NOT MEET THE REQUIREMENTS OF THE FINANCIAL RESPONSIBILITY LAW.

CALIFORNIA CIVIL CODE SECTION 2955.5. HAZARD INSURANCE DISCLOSURE: No lender shall require a borrower, as a condition of receiving or maintaining a loan
secured by real property, to provide hazard insurance coverage against risks to the improvements on that real property in an amount exceeding the replacement value of the improvements on the property.

EXHIBIT A

COLLATERAL DESCRIPTION ATTACHMENT

TO UCC NATIONAL FORM FINANCING STATEMENT

All personal property of Borrower
(herein referred to as Borrower or Debtor) whether presently existing or hereafter created or acquired, and wherever located, including, but not limited to:

(a) all accounts (including health-care-insurance receivables), chattel paper (including tangible and electronic chattel paper), deposit
accounts, documents (including negotiable documents), equipment (including all accessions and additions thereto), general intangibles (including payment intangibles and software), goods (including fixtures), instruments (including promissory notes),
inventory (including all goods held for sale or lease or to be furnished under a contract of service, and including returns and repossessions), investment property (including securities and securities entitlements), letter of credit rights, money,
and all of Debtors books and records with respect to any of the foregoing, and the computers and equipment containing said books and records;

(b) any and all cash proceeds and/or noncash proceeds of any of the foregoing, including, without limitation, insurance proceeds, and all supporting obligations and the security therefor or for any right
to payment. All terms above have the meanings given to them in the California Uniform Commercial Code, as amended or supplemented from time to time, including revised Division 9 of the Uniform Commercial Code-Secured Transactions, added by Stats.
1999, c.991 (S.B. 45), Section 35, operative July 1, 2001.

Notwithstanding the foregoing, the Collateral shall not
include (i) any of the ATEL Equipment Collateral (as such term is defined in that certain Loan and Security Agreement by and between Debtor and Comerica Bank dated as of November , 2010 or (ii) any
copyrights, patents, trademarks, servicemarks and applications therefor, now owned or hereafter acquired, or any claims for damages by way of any past, present and future infringement of any of the foregoing (collectively, the Intellectual
Property); provided, however, that the Collateral shall include all accounts and general intangibles that consist of rights to payment and proceeds from the sale, licensing or disposition of all or any part, or rights in, the foregoing (the
Rights to Payment). Notwithstanding the foregoing, if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property is necessary to have a security interest in the Rights
to Payment, then the Collateral shall automatically, and effective as of November , 2010, include the Intellectual Property to the extent necessary to permit perfection of Banks security interest in the
Rights to Payment.
