“Borrower”), and BIGBAND NETWORKS BAS, INC., a Delaware corporation (“BAS” and a “Borrower” and collectively with Parent “Borrowers”), provides the terms on which Bank shall
lend to Borrowers and Borrowers shall repay Bank. The parties agree as follows: 
 1 ACCOUNTING AND OTHER TERMS 
 Accounting terms not defined in this Agreement shall be construed following GAAP. Calculations and determinations must be made following GAAP. Capitalized
terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent such terms are
defined therein. 
 2 LOAN AND TERMS OF PAYMENT 
 2.1 Promise to Pay. Borrowers hereby jointly and severally unconditionally promise to pay Bank the outstanding principal amount of all Credit Extensions and accrued and unpaid interest thereon as and
when due in accordance with this Agreement. 
 2.1.1 Revolving Advances. 
 (a) Availability. Subject to the terms and conditions of this Agreement, Bank shall make Advances not exceeding the Availability
Amount. Amounts borrowed under the Revolving Line may be repaid and, prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein. 
 (b) Termination; Repayment. The Revolving Line terminates on the Revolving Line Maturity Date, when the principal amount of all
Advances, the unpaid interest thereon, and all other Obligations relating to the Revolving Line shall be immediately due and payable. 
 2.1.2 Letters of Credit Sublimit. 
 (a) As part of the Revolving Line, Bank shall issue or have issued
Letters of Credit for a Borrower’s account. The face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) may not exceed the Availability Amount. Such aggregate amounts
utilized hereunder shall at all times reduce the amount otherwise available for Advances under the Revolving Line. If, on the Revolving Maturity Date, there are any outstanding Letters of Credit, then on such date Borrowers are jointly and severally
obligated to provide to Bank cash collateral in an amount equal to 105% of the face amount of all such Letters of Credit plus all interest, fees, and costs due or to become due in connection therewith (as estimated by Bank in its good faith business
judgment), to secure all of the Obligations relating to said Letters of Credit. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of Bank’s standard
Application and Letter of Credit Agreement (the “Letter of Credit Application”). Borrowers jointly and severally agree to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request.
Borrowers further jointly and severally agree to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for a Borrower’s account or by Bank’s interpretations of any Letter of
Credit issued by Bank for a Borrower’s account, and each Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following a Borrower’s instructions or
those contained in the Letters of Credit or any modifications, amendments, or supplements thereto. 
 (b) The obligation of
Borrowers to immediately reimburse Bank for drawings made under Letters of Credit shall be absolute, unconditional, and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, such Letters of Credit, and the
Letter of Credit Application. 
 (c) A Borrower may request that Bank issue a Letter of Credit payable in a Foreign Currency.
If a demand for payment is made under any such Letter of Credit, Bank shall treat such demand as an 










 
Advance to Borrowers of the equivalent of the amount thereof (plus fees and charges in connection therewith such as wire, cable, SWIFT or similar charges) in
Dollars at the then-prevailing rate of exchange in San Francisco, California, for sales of the Foreign Currency for transfer to the country issuing such Foreign Currency. 
 (d) To guard against fluctuations in currency exchange rates, upon the issuance of any Letter of Credit payable in a Foreign Currency,
Bank shall create a reserve (the “Letter of Credit Reserve”) under the Revolving Line in an amount equal to ten percent (10%) of the face amount of such Letter of Credit. The amount of the Letter of Credit Reserve may be
adjusted by Bank from time to time to account for fluctuations in the exchange rate. The availability of funds under the Revolving Line shall be reduced by the amount of such Letter of Credit Reserve for as long as such Letter of Credit remains
outstanding. 
 2.1.3 Foreign Exchange Sublimit. As part of the Revolving Line, Borrowers may enter into foreign exchange
contracts with Bank under which Borrowers jointly and severally commit to purchase from or sell to Bank a specific amount of Foreign Currency (each, a “FX Forward Contract”) on a specified date (the “Settlement
Date”). FX Forward Contracts shall have a Settlement Date of at least one (1) FX Business Day after the contract date and shall be subject to a reserve of ten percent (10%) of each outstanding FX Forward Contract in a maximum
aggregate amount equal to the Revolving Line Limit (the “FX Reserve”). The aggregate amount of FX Forward Contracts at any one time may not exceed ten (10) times the amount of the FX Reserve. 
 2.1.4 Cash Management Services Sublimit. Borrowers may use up to the Revolving Line Limit (the “Cash Management Services
Sublimit”) of the Revolving Line for Bank’s cash management services which may include merchant services, direct deposit of payroll, business credit card, and check cashing services identified in Bank’s various cash management
services agreements (collectively, the “Cash Management Services”). Any amounts Bank pays on behalf of a Borrower or any amounts that are not paid by Borrowers for any Cash Management Services will be treated as Advances under the
Revolving Line and will accrue interest at the interest rate applicable to Advances. 
 2.1.5 Term Loan. 
 (a) Availability. Bank shall make one (1) term loan available to Borrowers in an amount up to the Term Loan Amount on or not
later than thirty (30) days after the Effective Date subject to the satisfaction of the terms and conditions of this Agreement. 
 (b) Repayment. Borrowers shall be jointly and severally obligated to repay the Term Loan in twenty-four (24) equal installments of principal (the “Term Loan Payment”). Beginning on the
last Business Day of the month following the first anniversary of the month in which the Funding Date occurs, each Term Loan Payment shall be payable on the last of each month. Borrowers’ final Term Loan Payment, due on the Term Loan Maturity
Date, shall include all outstanding principal and accrued and unpaid interest under the Term Loan. 
 (c) Prepayment.
At Borrowers’ option, so long as an Event of Default has not occurred and is not continuing, Borrowers shall have the option, at any time and from time to time, to prepay all or not less than 25% of the Term Loan Amount advanced by Bank under
this Agreement, without premium or penalty, provided Borrowers (a) provide written notice to Bank of their election to exercise to prepay the Term Loan at least three (3) days prior to such prepayment, and (b) pay, on the date
of the prepayment (i) all accrued and unpaid interest with respect to the Term Loan through the date the prepayment is made; (ii) all unpaid principal with respect to the Term Loan; and (iii) all other sums, if any, that shall have
become due and payable hereunder with respect to this Agreement. 
 2.2 Overadvances. If, at any time, the Credit Extensions
under Sections 2.1.1, 2.1.2, 2.1.3 and 2.1.4 exceed the lesser of either (a) the Revolving Line or (b) the Borrowing Base, Borrowers shall be jointly and severally obligated to immediately pay to Bank in cash such excess.

 2.3 Payment of Interest on the Credit Extensions. 
 (a) Interest Rate. 
 (i) Advances. Subject to Section 2.3(b), the principal amount outstanding under the Revolving Line shall accrue interest at a floating per annum rate equal to the Prime Rate, which interest shall be
payable monthly in accordance with Section 2.3(f) below; provided, however, that during each Adjustment Period, interest shall accrue at a floating per annum rate equal to one and one half percentage point above the Prime Rate.

 (ii) Term Loan. Subject to Section 2.3(b), the principal amount outstanding under the Term Loan shall accrue
interest at a floating per annum rate equal to one quarter of one percentage point above the Prime Rate, which interest shall be payable monthly; provided, however, that during each Adjustment Period, interest shall accrue at a
floating per annum rate equal to one and one half percentage point above the Prime Rate. 
 (b) Default Rate.
Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall bear interest at a rate per annum which is five percentage points above the rate effective immediately before the Event of Default (the
“Default Rate”). Payment or acceptance of the increased interest rate provided in this Section 2.3(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise
prejudice or limit any rights or remedies of Bank. 
 (c) Adjustment to Interest Rate. Changes to the interest rate of
any Credit Extension based on changes to the Prime Rate shall be effective on the effective date of any change to the Prime Rate and to the extent of any such change. 
 (d) 360-Day Year. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed. 
 (e) Debit of Accounts. Bank may debit any of either Borrower’s deposit accounts, including the Designated Deposit Account, for
principal and interest payments or any other amounts Borrowers owe Bank when due. These debits shall not constitute a set-off. 
 (f) Payments. Unless otherwise provided, interest is payable monthly on the last Business Day of each month. Payments of principal and/or interest received after 12:00 p.m. Pacific time are considered received at the opening of
business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue. Bank’s receipt of any check or
other item of payment shall be immediately applied to conditionally reduce the Obligations but shall not be considered a payment on account until three (3) Business Days after the date that such check or other payment item is received by Bank.
Bank’s receipt of any wire transfer shall be considered a payment on account and shall be immediately applied to reduce the Obligations. 
 (g) Lockbox Account. Borrowers shall cause all payments with respect to the Accounts to be made to the lockbox account at the Bank (the “Lockbox Account”). During an Adjustment Period, cash
collections and deposits to the Lockbox Account will be directed daily to a cash collateral account under Bank’s control, and Bank shall apply the funds in such cash collateral account to reduce the Obligations. After all the Obligations are so
satisfied, any remaining funds in such cash collateral account shall be directed to the Designated Deposit Account. 
 2.4 Fees.
Borrowers are jointly and severally obligated to pay to Bank: 
 (a) Commitment Fee. A fully earned,
non-refundable commitment fee of $105,000, on the Effective Date ($50,000 of which Borrowers paid as the good faith deposit) and a fully earned, non-refundable annual facility fee equal to one half of one percent (0.50%) of the Revolving Line, due
on each anniversary of the Effective Date; 
 (b) Collateral Handling Fee. A collateral handling fee (the
“Collateral Handling Fee”) on the last Business Day of each month, which shall be fully-earned and non-refundable on such date. The Collateral Handling Fee for each month shall be $2,000, unless the Adjusted Quick Ratio for
immediately preceding month is less than 1.15 to 1.00, in which case it shall be $4,000; provided, however, that the Collateral Handling Fee shall not be due and payable in any month if average outstanding Advances for the immediately
preceding month was $2,000,000 or greater; 
  

 -3- 








 (c) Letter of Credit Fee. Bank’s customary fees and expenses for the issuance
or renewal of Letters of Credit, including, without limitation, a Letter of Credit Fee of one percent (1.00%) per annum of the face amount of each Letter of Credit issued, upon the issuance, each anniversary of the issuance, and the renewal of
such Letter of Credit; 
 (d) Unused Revolving Line Facility Fee. A fee (the “Unused Revolving Line Facility
Fee”), payable quarterly, in arrears and fully-earned, on a calendar year basis, in an amount equal to 0.15% per annum of the average unused portion of the Revolving Line, as determined by Bank, if the Revolving Line principal
outstanding was zero on any day during the preceding quarter; 
 (e) Termination Fee. A fee (the “Termination
Fee”) of (i) three quarters of one percent (0.75%) of the Revolving Line Amount if the Revolving Line is terminated by Borrowers for any reason or no reason prior to the first anniversary of the Effective Date, and (ii) one half
of one percent (0.50%) of the Revolving Line Amount if the Revolving Line is terminated by Borrowers for any reason or no reason on or after the first anniversary of the Effective Date; provided, however, that the Termination Fee shall
not be due and payable if Borrowers enter into a new credit facility with Bank concurrent with the termination of the Revolving Line; and 
 (f) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses, plus expenses, for documentation and negotiation of this Agreement) incurred through and after the Effective Date,
when due.

 4 CREATION OF SECURITY INTEREST 
 4.1 Grant of Security Interest. Each Borrower hereby grants Bank, to secure the payment and performance in full of all of the Obligations, a
continuing security interest in, and pledges to Bank, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Borrowers jointly and severally represent, warrant, and covenant that
the security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens that may have superior priority to Bank’s Lien under this Agreement).
If a Borrower shall acquire a commercial tort claim, Borrowers shall promptly notify Bank in a writing signed by Borrowers of the general details thereof and grant to Bank in such writing a security interest therein and in the proceeds thereof, all
upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to Bank. 
 If this Agreement is
terminated, Bank’s Lien in the Collateral shall continue until the Obligations (other than inchoate indemnity obligations) are repaid in full in cash. Upon payment in full in cash of the Obligations and at such time as Bank’s obligation to
make Credit Extensions has terminated, Bank shall, at Borrowers’ sole cost and expense, release its Liens in the Collateral and all rights therein shall revert to Borrower. 
 4.2 Authorization to File Financing Statements. Borrowers hereby authorize Bank to file financing statements, without notice to Borrowers,
with all appropriate jurisdictions to perfect or protect Bank’s interest or rights hereunder. 
 5 REPRESENTATIONS AND
WARRANTIES 
 Borrowers jointly and severally represent and warrant as follows: 
 5.1 Due Organization and Authorization. Borrowers and each of their Subsidiaries are duly existing and in good standing in their respective
jurisdictions of formation and are qualified and licensed to do business and are in good standing in any jurisdiction in which the conduct of their business or their ownership of property requires that they be qualified except where the failure to
do so could not reasonably be expected to have a material adverse effect on Borrowers’ business. In connection with this Agreement, Borrowers have delivered to Bank completed certificates substantially in the form attached hereto as Exhibit
F, signed by Borrowers, entitled “Perfection Certificate”. Borrowers jointly and severally represent and warrant to Bank that (a) each Borrower’s exact legal name is that indicated on such Borrower’s Perfection
Certificate and on the signature page hereof; (b) each Borrower is an organization of the type and is organized in the jurisdiction set forth in such Borrower’s Perfection Certificate; (c) each Borrower’s Perfection Certificate
accurately sets forth such Borrower’s organizational identification number or accurately states that such Borrower has none; (d) each Borrower’s Perfection Certificate accurately sets forth such Borrower’s place of business, or,
if more than one, its chief executive office as well as such Borrower’s mailing address (if different than its chief executive office); (e) neither Borrower (nor any of its predecessors) has, in the past five (5) years, changed its
state of formation, organizational structure or type, or any organizational number assigned by its jurisdiction; and (f) all other information set forth on each Borrower’s Perfection Certificate pertaining to such Borrower and each of its
Subsidiaries is accurate and complete. If a Borrower is not now a Registered Organization but later becomes one, such Borrower shall promptly notify Bank of such occurrence and provide Bank with such Borrower’s organizational identification
number. 
 The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with either
Borrower’s organizational documents, nor constitute an event of default under any material agreement by which either Borrower is bound. Neither Borrower is in default under any agreement to which it is a party or by which it is bound in which
the default could reasonably be expected have a material adverse effect on such Borrower’s business. 
 5.2 Collateral.
Each Borrower has good title to, has rights in, and the power to transfer each item of the Collateral upon which it purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens. Neither Borrower has deposit accounts
other than the deposit accounts with Bank, the deposit accounts, if any, described in such Borrower’s Perfection Certificate delivered to Bank in connection herewith, or of which such Borrower has given Bank notice and taken such actions as are
necessary to give Bank a perfected security interest therein. The Accounts are bona fide, existing obligations of the Account Debtors. 
 Except as otherwise permitted by this Section 5.2, the Collateral is not in the possession of any third party bailee (such as a warehouse but excluding customers of Borrowers). Except as hereafter disclosed to the Bank in writing by
Borrowers, none of the components of the Collateral shall be maintained at locations other than as 

  

 -6- 








 
provided in the Perfection Certificates (except that Collateral may be maintained at customer locations in the ordinary course of business). A Borrower may
maintain Inventory and Equipment with third parties provided that the value of such Inventory and Equipment does not exceed $250,000 in aggregate at any time (not including Inventory and Equipment at customer locations in the ordinary course of
business). 
 Each Borrower is the sole owner of its intellectual property, except for non-exclusive licenses granted to its customers in the
ordinary course of business. Each patent is valid and enforceable, and no part of the intellectual property has been judged invalid or unenforceable, in whole or in part, and to the best of Borrowers’ knowledge, no claim has been made that any
part of the intellectual property violates the rights of any third party except to the extent such claim could not reasonably be expected to have a material adverse effect on Borrower’s business. 
 5.3 Accounts Receivable. For any Eligible Account, Eligible Foreign Account and Eligible Special Account in any Borrowing Base Certificate,
all statements made and all unpaid balances appearing in all invoices, instruments and other documents evidencing such Eligible Accounts, Eligible Foreign Accounts and Eligible Special Accounts are and shall be true and correct and all such
invoices, instruments and other documents, and all of Borrowers’ Books are genuine and in all respects what they purport to be. All sales and other transactions underlying or giving rise to each Eligible Account, Eligible Foreign Account and
Eligible Special Account shall comply in all material respects with all applicable laws and governmental rules and regulations. Borrowers have no knowledge of any actual or imminent Insolvency Proceeding of any Account Debtor whose accounts are an
Eligible Account, Eligible Foreign Account or Eligible Special Account in any Borrowing Base Certificate. To the best of Borrowers’ knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all
Eligible Accounts, Eligible Foreign Accounts and Eligible Special Accounts are genuine, and all such documents, instruments and agreements are legally enforceable in accordance with their terms. 
 5.4 Litigation. There are no actions or proceedings pending or, to the knowledge of the Responsible Officers, threatened in writing by or
against either Borrower or any of its Subsidiaries that could reasonably be expected to result in damages that exceed insurance coverage by more than $500,000. 
 5.5 Financial Statements. All consolidated financial statements of Parent and its Subsidiaries delivered to Bank fairly present in all material respects Parent’s consolidated financial condition and
Parent’s consolidated results of operations (subject to normal year-end adjustment in the case of unaudited financial statements). 
 5.6 Solvency. The fair salable value of each Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; neither Borrower is left with unreasonably small capital after the
transactions in this Agreement; and each Borrower is able to pay its debts (including trade debts) as they mature. 
 5.7
Regulatory Compliance. Neither Borrower is an “investment company” or a company “controlled” by an “investment company” under the Investment Company Act. Neither Borrower is engaged as one of its important
activities in extending credit for margin stock (under Regulations T and U of the Federal Reserve Board of Governors). Each Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower has violated any
laws, ordinances or rules, the violation of which could reasonably be expected to have a material adverse effect on its business. None of either Borrower’s or any of its Subsidiaries’ properties or assets has been used by such Borrower or
any such Subsidiary or, to the best of Borrowers’ knowledge, by previous Persons, in disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Each Borrower and each of its Subsidiaries have obtained
all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all government authorities that are necessary to continue its business as currently conducted. 
 5.8 Subsidiaries; Investments. Neither Borrower owns any stock, partnership interest or other equity securities except for Permitted
Investments. 
 5.9 Tax Returns and Payments; Pension Contributions. Each Borrower, or Parent on behalf of such Borrower, has
timely filed all required tax returns and reports, and each Borrower has timely paid all foreign, federal, state and local taxes, assessments, deposits and contributions owed by such Borrower. A Borrower may defer payment of any contested taxes,
provided that Parent or such Borrower (a) in good faith contests its obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Bank in writing of the commencement of, and any
material development in, the proceedings, (c) posts bonds or takes any 

  

 -7- 








 
other steps required to prevent the governmental authority levying such contested taxes from obtaining a Lien upon any of the Collateral that is other than a
“Permitted Lien”. Borrowers are unaware of any claims or adjustments proposed for any of either Borrower’s prior tax years which could result in additional taxes becoming due and payable by either Borrower. Each Borrower has paid all
amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms, and neither Borrower has withdrawn from participation in, and has not permitted partial or complete termination of, or
permitted the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any material liability of either Borrower, including any material liability to the Pension Benefit Guaranty Corporation or its
successors or any other governmental agency. 
 5.10 Use of Proceeds. Borrowers shall use the proceeds of the Credit Extensions
solely as working capital, to repay the Indebtedness owed to Horizon Technology Funding Company LLC and ADC Telecommunications Inc. and to fund their general business requirements and not for personal, family, household or agricultural purposes.

 5.11 Full Disclosure. No written representation, warranty or other statement of either Borrower in any certificate or
written statement given to Bank, as of the date such representations, warranties, or other statements were made, taken together with all such written certificates and written statements given to Bank, contains any untrue statement of a material fact
or omits to state a material fact necessary to make the statements contained in the certificates or statements not misleading (it being recognized by Bank that the projections and forecasts provided by Borrowers in good faith and based upon
reasonable assumptions are not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ from the projected or forecasted results). 
 6 AFFIRMATIVE COVENANTS 
 Each
Borrower shall do all of the following: 
 6.1 Government Compliance. Except as is permitted under Section 7.3 and except
to the extent that a liquidation of a Subsidiary would result in another Subsidiary owning such Subsidiary’s assets, maintain its and all its Subsidiaries’ legal existence and good standing in their respective jurisdictions of formation
and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on such Borrower’s business or operations. Such Borrower shall comply, and have each of its
Subsidiaries comply, with all laws, ordinances and regulations to which it is subject, noncompliance with which could have a material adverse effect on either Borrower’s business.

monthly basis while no Advances are outstanding under the Revolving Line. 
 (e) Allow Bank to audit Borrower’s
Collateral at Borrower’s expense. Such audits shall be conducted no more often than once every six (6) months unless (i) a Default or an Event of Default has occurred and is continuing, or (ii) if Bank believes there has been a
deterioration in the Collateral or the Borrowers’ financial performance at any time during an Adjustment Period. 
 6.3
Inventory; Returns. Keep all Inventory in good and marketable condition, free from material defects. Returns and allowances between each Borrower and its Account Debtors shall follow such Borrower’s customary practices as they exist at
the Effective Date or as are disclosed to Bank from time to time. Borrowers must promptly notify Bank of all returns, recoveries, disputes and claims that involve the greater of (i) Five Hundred Thousand Dollars ($500,000) or (ii) five
percent (5%) of the amount of the invoice with respect to which the return, recovery, dispute or claim relates. 
 6.4 Taxes;
Pensions. Make, and cause each of its Subsidiaries to make, timely payment of all foreign, federal, state, and local taxes or assessments (other than taxes and assessments which such Borrower is contesting pursuant to the terms of
Section 5.9 hereof) and shall deliver to Bank, on demand, appropriate certificates attesting to such payments, and pay all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their
terms. 
 6.5 Insurance. Keep its business and the Collateral insured for risks and in amounts standard for companies in
Borrower’s industry and location and as Bank may reasonably request. Insurance policies shall be in a form, with companies, and in amounts that are satisfactory to Bank. All property policies shall have a lender’s loss payable endorsement
showing Bank as lender loss payee and waive subrogation against Bank, and all liability policies shall show, or have endorsements showing, Bank as an additional insured. All policies (or the loss payable and additional insured endorsements) shall
provide that the insurer must give Bank at least twenty (20) days notice before canceling, amending, or declining to renew its policy. At Bank’s request, Borrower shall deliver certified copies of policies and evidence of all premium
payments. Proceeds payable under any policy shall, at Bank’s option, be payable to Bank on account of the Obligations. Notwithstanding the foregoing, (a)(x) so long as no Event of Default has occurred and is continuing, Borrower shall have the
option of applying the proceeds of any casualty policy toward the replacement or repair of destroyed or damaged property; provided that any such replaced or repaired property (i) shall be of equal or like value as the replaced or repaired
Collateral and (ii) shall be deemed Collateral in which Bank has been granted a first priority security interest, and (b)(y) 

  

 -9-

Account is maintained to execute and deliver a Control Agreement or other appropriate instrument with respect to such Collateral Account to perfect Bank’s Lien in such Collateral Account in accordance with the terms hereunder. The provisions of
the previous sentence shall not apply to deposit accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of a Borrower’s employees and identified to Bank by such Borrower as such.

 6.7 Financial Covenant. Borrowers shall maintain at all times, to be tested as of the last day of each fiscal quarter, on a
consolidated basis with respect to Borrowers and their Subsidiaries a Tangible Net Worth of greater than negative $6,000,000. 
 6.8
Protection of Intellectual Property Rights. Such Borrower shall: (a) protect, defend and maintain the validity and enforceability of its intellectual property; (b) promptly advise Bank in writing of material infringements of its
intellectual property; and (c) not allow any intellectual property material to such Borrower’s business to be abandoned, forfeited or dedicated to the public, except in the cases of clauses (a) and (c) where such Borrower’s
General Counsel or Chief Technology Officer determines in its reasonable business judgment that such action (or inaction) is in such Borrower’s best interest. 
 6.9 Litigation Cooperation. From the date hereof and continuing through the termination of this Agreement, make available to Bank, without expense to Bank, such Borrower and its officers, employees and
agents and such Borrower’s books and records, to the extent that Bank may deem them reasonably necessary to prosecute or defend any third-party suit or proceeding instituted by or against Bank with respect to any Collateral or relating to such
Borrower.

reasonably requests to perfect or continue Bank’s Lien in the Collateral or to effect the purposes of this Agreement. 
 7

the United States.

of its Subsidiaries to engage in any business other than the businesses currently engaged in by Parent and its Subsidiaries, as applicable, or reasonably related or incidental thereto; (b) liquidate or dissolve (provided that BAS or any other

 -10- 








 
change in Senior Manager (unless a replacement is approved by a majority of the Compensation Committee of such Borrower’s Board of Directors, within 180
days of the date of termination such Senior Manager) or (ii) enter into any transaction or series of related transactions in which the stockholders of Parent who were not stockholders immediately prior to the first such transaction own more
than 40% of the voting stock of Parent immediately after giving effect to such transaction or related series of such transactions (other than by the sale of Parent’s equity securities in a public offering or to venture capital investors or
strategic investors). Such Borrower shall not, without at least thirty (30) days prior written notice to Bank: (1) add any new offices or business locations, including warehouses (unless such new offices or business locations contain less

(5) change any organizational number (if any) assigned by its jurisdiction of organization. 
 7.3 Mergers or

capital stock or property of another Person except that a Subsidiary may merge or consolidate into, or acquire all or substantially all of the assets of, another Subsidiary or into a Borrower and a Borrower may merge or consolidate into, or acquire
all or substantially all of the assets of, the other Borrower. 
 7.4 Indebtedness. Create, incur, assume, or be liable for any
Indebtedness, or permit any Subsidiary to do so, other than Permitted Indebtedness. 
 7.5 Encumbrance. Create, incur, or allow

priority security interest granted herein. 
 7.6 Maintenance of Collateral Accounts. Maintain any Collateral Account except

common stock; and (iii) such Borrower may repurchase the stock of former employees, directors or consultants pursuant to stock repurchase agreements so long as an Event of Default does not exist at the time of such repurchase and would not

 7.8 Transactions with Affiliates. Directly or indirectly enter into or permit to exist any material transaction with any Affiliate of such Borrower, except for transactions that are in the ordinary course of such
Borrower’s business, so long as such transaction does not have a material adverse impact upon the consolidated financial position of Parent, and, in the case of a transaction with an Affiliate that is not Parent or any of its Subsidiaries, such
transaction is no less favorable to such Borrower than would be obtained in an arm’s length transaction with a non-affiliated Person. 
 7.9 Subordinated Debt. (a) Make or permit any payment on any Subordinated Debt, except under the terms of the subordination, intercreditor, or other similar agreement to which such Subordinated Debt is subject, or
(b) amend any provision in any document relating to the Subordinated Debt which would increase the amount thereof or adversely affect the subordination thereof to Obligations owed to Bank.

partial or

which could reasonably be expected to result in any material liability of such Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency. 
 8 EVENTS OF DEFAULT 
 Any one
of the following shall constitute an event of default (an “Event of Default”) under this Agreement: 
 8.1 Payment
Default. Borrowers fail to (a) make any payment of principal or interest on any Credit Extension on its due date, or (b) pay any other Obligations within three (3) Business Days after such Obligations are due and payable. During
the cure period, the failure to cure the payment default is not an Event of Default (but no Credit Extension will be made during the cure period); 
 8.2 Covenant Default. 
 (a) Either Borrower fails or neglects to perform any obligation in Sections
6.2 (excluding clauses (iv) and (v) of Section 6.2(a)), 6.5, 6.6, or 6.7 or violates any covenant in Section 7; or 
 (b) Either Borrower fails or neglects to perform, keep, or observe any other term, provision, condition, covenant or agreement contained in this Agreement, any Loan Documents, and as to any default (other than those
specified in this Section 8) under such other term, provision, condition, covenant or agreement that can be cured, has failed to cure the default within ten (10) days after the occurrence thereof; provided, however, that if
the default cannot by its nature be cured within the ten (10) day period or cannot after diligent attempts by a Borrower be cured within such ten (10) day period, and such default is likely to be cured within a reasonable time, then such
Borrower shall have an additional period (which shall not in any case exceed thirty (30) days) to attempt to cure such default, and within such reasonable time period the failure to cure the default shall not be deemed an Event of Default (but
no Credit Extensions shall be made during such cure period). Grace periods provided under this section shall not apply, among other things, to financial covenants or any other covenants set forth in subsection (a) above; 
 8.3 Material Adverse Change. A Material Adverse Change occurs; 
 8.4 Attachment. (a) Any material portion of either Borrower’s assets is attached, seized, levied on, or comes into possession of
a trustee or receiver and the attachment, seizure or levy is not removed in ten (10) days; (b) the service of process upon Bank seeking to attach, by trustee or similar process, any funds of either Borrower or of any entity under control
of either Borrower (including a Subsidiary) on deposit with Bank if such service of process or attachment is not rescinded with 10 days; (c) either Borrower is enjoined, restrained, or prevented by court order from conducting a material part of
its business; (d) a judgment or other claim in excess of One Million Dollars ($1,000,000) becomes a Lien on any material portion of either Borrower’s assets; or (e) a notice of lien, levy, or assessment is filed against any of either
Borrower’s assets by any government agency and not paid or appropriately contested within ten (10) days after such Borrower receives notice. These are not Events of Default if stayed or if a bond is posted pending contest by a Borrower
(but no Credit Extensions shall be made during the cure period); 
 8.5 Insolvency. (a) Either Borrower is unable to pay
its debts (including trade debts) as they become due or otherwise becomes insolvent; (b) either Borrower begins an Insolvency Proceeding; or (c) an Insolvency Proceeding is begun against either Borrower and not dismissed or stayed within
thirty (30) days (but no Credit Extensions shall be made while of any of the conditions described in clause (a) exist and/or until any Insolvency Proceeding is dismissed); 
 8.6 Other Agreements. There is a default in any agreement to which either Borrower or any Guarantor is a party with a third party or
parties resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity of any Indebtedness in an amount in excess of One Million Dollars ($1,000,000); 
  

 -12- 








 8.7 Judgments. A judgment or judgments for the payment of money in an amount, individually
or in the aggregate, of at least One Million Dollars ($1,000,000) (not covered by independent third-party insurance) shall be rendered against either Borrower and shall remain unsatisfied and unstayed for a period of ten (10) days after the
entry thereof (provided that no Credit Extensions will be made prior to the satisfaction or stay of such judgment); 
 8.8
Misrepresentations. A Borrower or any Person acting for a Borrower makes any representation, warranty, or other statement now or later in this Agreement, any Loan Document or in any writing delivered to Bank or to induce Bank to enter this
Agreement or any Loan Document, and such representation, warranty, or other statement is incorrect in any material respect when made; 
 8.9 Subordinated Debt. A default or breach occurs under any agreement between either Borrower and any creditor of such Borrower that signed a subordination, intercreditor, or other similar agreement with Bank, or any creditor
that has signed such an agreement with Bank breaches any terms of such agreement; or 
 8.10 Guaranty. (a) Any guaranty of any
Obligations terminates or ceases for any reason to be in full force and effect; (b) any Guarantor does not perform any obligation or covenant under any guaranty of the Obligations; (c) any circumstance described in Sections 8.3, 8.4, 8.5,
8.6, 8.7, or 8.8. occurs with respect to any Guarantor, or (d) the liquidation, winding up, or termination of existence of any Guarantor that is not permitted under this Agreement. 
 9 BANK’S RIGHTS AND REMEDIES 
 9.1 Rights and Remedies. While an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following: 
 (a) declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations
are immediately due and payable without any action by Bank); 
 (b) stop advancing money or extending credit for
Borrowers’ benefit under this Agreement or under any other agreement between Borrowers and Bank; 
 (c) demand that
Borrowers (i) deposit cash with Bank in an amount equal to the aggregate amount of any Letters of Credit remaining undrawn, as collateral security for the repayment of any future drawings under such Letters of Credit, and Borrowers shall
forthwith deposit and pay such amounts, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable over the remaining term of any Letters of Credit; 
 (d) terminate any FX Contracts; 
 (e) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Bank considers advisable, notify any Person owing a Borrower money of Bank’s security interest in
such funds, and verify the amount of such account; 
 (f) make any payments and do any acts it considers necessary or
reasonable to protect the Collateral and/or its security interest in the Collateral. Borrowers shall assemble the Collateral if Bank requests and make it available as Bank designates. Bank may enter premises where the Collateral is located, take and
maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Each Borrower grants Bank a license to enter and
occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies; 
 (g) apply to the Obligations
any (i) balances and deposits of Borrowers it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrowers; 
 (h) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Bank is hereby granted a non-exclusive, royalty-free license or other right to use, without
charge, each Borrower’s labels, patents, copyrights, mask works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property 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 

  

 -13- 








 
its rights under this Section, each Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; 
 (i) place a “hold” on any account maintained with Bank and/or deliver a notice of exclusive control, any entitlement order, or
other directions or instructions pursuant to any Control Agreement or similar agreements providing control of any Collateral; 
 (j) demand and receive possession of Borrowers’ Books; and 
 (k) exercise all rights and remedies available to
Bank under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof). 
 9.2 Power of Attorney. Each Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to:
(a) endorse such Borrower’s name on any checks or other forms of payment or security; (b) sign such Borrower’s name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust
disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle, and adjust all claims under such Borrower’s insurance policies; (e) pay, contest or settle
any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Bank
or a third party as the Code permits. Each Borrower hereby appoints Bank as its lawful attorney-in-fact to sign such Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether
an Event of Default has occurred until all Obligations have been satisfied in full and Bank is under no further obligation to make Credit Extensions hereunder. Bank’s foregoing appointments as Borrowers’ attorney in fact, and all of
Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates. 
 9.3 Accounts Verification; Collection. Borrowers agree that upon Bank’s request, they shall blind copy Bank on email collection
efforts involving Accounts of $500,000 or more and Accounts more than ninety (90) days from invoice date. If an Event of Default has occurred and is continuing for which Bank has accelerated payment of the Obligations or if Borrowers fail to
comply in any material respect with a Bank request in accordance with the preceding sentence, Bank may notify any Person owing a Borrower money of Bank’s security interest in such funds and verify the amount of such account. After the
occurrence and during the continuance of an Event of Default, any amounts received by Borrowers shall be held in trust by Borrowers for Bank, and, if requested by Bank, Borrowers shall immediately deliver such receipts to Bank in the form received
from the Account Debtors, with proper endorsements for deposit. 
 9.4 Protective Payments. If a Borrower fails to obtain the
insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which Borrowers are obligated to pay under this Agreement or any other Loan Document, Bank may obtain such insurance or make such payment,
and all amounts so paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then highest applicable rate, and secured by the Collateral. Bank will make reasonable efforts to provide Borrowers with notice of Bank
obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default. 
 9.5 Application of Payments and Proceeds. Unless an Event of Default has occurred and is continuing, Bank shall apply any funds in its
possession (other than funds maintained in Borrowers’ deposit and investment accounts with Bank which are not the proceeds of Collateral dispositions prohibited hereunder), whether from a Borrower’s account balances, payments, or proceeds
realized as the result of any collection of Accounts or other disposition of the Collateral, first, to Bank Expenses, including without limitation, the reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by Bank in
the exercise of its rights under this Agreement; second, to the interest due upon any of the Obligations; and third, to the principal of the Obligations and any applicable fees and other charges, in such order as Bank shall determine in its sole
discretion. Any surplus shall be paid to Borrowers or other Persons legally entitled thereto; Borrowers shall remain jointly and severally liable to Bank for any deficiency. If an Event of Default has occurred and is continuing, Bank may apply any
funds in its possession, whether from a Borrower’s account balances, payments, proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Bank shall


  

 -14- 








 
determine in its sole discretion. Any surplus shall be paid to Borrowers or other Persons legally entitled thereto; Borrowers shall remain jointly and
severally liable to Bank for any deficiency. If Bank, in its good faith business judgment, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Bank shall have the option,
exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Bank of cash therefor. Any surplus funds remaining after the
Obligations are satisfied in full shall be paid to Borrowers or other Persons legally entitled thereto. Borrowers shall remain jointly and severally liable to Bank for any deficiency. 
 9.6 Bank’s Liability for Collateral. So long as Bank complies with reasonable banking practices regarding the safekeeping of the
Collateral in the possession or under the control of Bank, Bank shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the
Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrowers bear all risk of loss, damage or destruction of the Collateral. 
 9.7 No Waiver; Remedies Cumulative. Bank’s failure, at any time or times, to require strict performance by a Borrower or Borrowers of
any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Bank thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by
Bank and then is only effective for the specific instance and purpose for which it is given. Bank’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Bank has all rights and remedies provided under the Code,
by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay in exercising any remedy is not a waiver, election, or acquiescence.

 9.8 Demand Waiver. Each Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of
any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrowers are liable. 
 10 NOTICES AND WAIVERS 
 10.1 Notices. 
 All notices, consents, requests, approvals, demands, or other communication (collectively,
“Communication”) by any party to this Agreement or any other Loan Document must be in writing and shall be deemed to have been validly served, given, or delivered: (a) upon the earlier of actual receipt and three
(3) Business Days after deposit in the U.S. mail, first class, registered or certified mail return receipt requested, with proper postage prepaid; (b) upon transmission, when sent by electronic mail or facsimile transmission; (c) one

 10.2 Subrogation and Similar Rights. 
 Notwithstanding any other provision of this Agreement or any other Loan Document, until the Obligations have been full and finally paid (other than
inchoate indemnity and performance obligations), each Borrower irrevocably waives all rights that it may have at law or in equity (including any law subrogating the Borrower to the rights of Bank under the Loan Documents) to seek contribution,
indemnification, or any other form of reimbursement from the other Borrower, or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, for any payment made by the Borrower with respect to the Obligations in
connection with the Loan Documents or otherwise and all rights that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by the Borrower with respect to the Obligations in connection
with the Loan Documents or otherwise. Any agreement providing for indemnification, reimbursement or any other arrangement prohibited under this Section 10.2 shall be null and void. If any payment is made to a Borrower in contravention of this
Section 10.2, such Borrower shall hold such payment in trust for Bank and such payment shall be promptly delivered to Bank for application to the Obligations, whether matured or unmatured. 
 10.3 Waivers of Defenses. 
 Each
Borrower, to the extent that it is a guarantor of the Obligations, waives any defense arising from any defense of the other Borrower, or by reason of the cessation from any cause whatsoever of the liability of the other Borrower. Nothing contained
herein shall prevent Bank from foreclosing on the Lien of any security instrument, or exercising any rights available thereunder, and the exercise of any such rights shall not constitute a legal or equitable discharge of either Borrower. Each
Borrower, to the extent that it is a guarantor of the Obligations, also waives any defense arising from any act or omission of Bank that changes the scope of the Borrower’s risks hereunder. Each Borrower, to the extent that it is a guarantor of
the Obligations, waives any right to assert against Bank any defense (legal or equitable), setoff, counterclaim, or claims that such Borrower individually may now or hereafter have against the other Borrower or any other Person liable to Borrower
with respect to the Obligations in any manner or whatsoever. Each Borrower assumes the responsibility for being and keeping itself informed of the other Borrower’s financial condition and of all other circumstances bearing on the risk of
nonpayment of the Obligations and that Bank shall have no duty to advise it of information that Bank has regarding the foregoing. 
 10.4
Waiver of Guarantor Defenses. 
 Each Borrower, to the extent that it is a guarantor of the Obligations and to the extent permitted by
law, waives any defense based on impairment or destruction of its subrogation or other rights against the other Borrower and waives all benefits which might otherwise be available to it under California Civil Code §§ 2809, 2810, 2819,
2839, 2845, 2847, 2848, 2849, 2850, 2899 and 3433 and California Code of Civil Procedure §§ 580a, 580b, 580d and 726, as those statutory provisions are now in effect and hereafter amended, and under any other similar statutes now and
hereafter in effect. 
  

 -16- 








 10.5 Right to Settle, Release. 
 (a) Each Borrower’s liability hereunder shall not be diminished by (i) any agreement, understanding or representation that any
of the Obligations is or was to be guaranteed by another Person or secured by other property, or (ii) any release or unenforceability, whether partial or total, or rights, if any, which Borrower may now or hereafter have against any other
Person, including the other Borrower, or property with respect to any of the Obligations. 
 (b) Without notice to the other

 11 CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE 
 California law governs the Loan Documents without regard to principles of conflicts of law. Each Borrower and Bank each submit to the exclusive
jurisdiction of the State and Federal courts in Santa Clara County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Bank from bringing suit or taking other legal action in any other
jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Bank. Each Borrower expressly submits and consents in advance to such jurisdiction in any action or suit
commenced in any such court, and each Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is
deemed appropriate by such court. Each Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by
registered or certified mail addressed to such Borrower at the address set forth in Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of a Borrower’s actual receipt thereof or three
(3) days after deposit in the U.S. mails, proper postage prepaid. 
 TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH BORROWER
AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE OTHER LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS.
THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 
 WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’ AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes
or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of the Santa Clara County, California Superior
Court) appointed in accordance with California Code of Civil Procedure § 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa
Clara County, California; and the parties hereby submit to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through
645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All
such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that
point pursuant to the judicial reference procedures, then such party may apply to the Santa Clara County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the 

  

 -17- 








 
same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which
shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and order applicable to judicial
proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of
decision thereon pursuant to the California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies.
The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

cross-references.]
