     This TERM LOAN AND SECURITY AGREEMENT (the “Agreement”) dated October 6, 2005 by and among SILICON VALLEY BANK, a California-chartered bank, with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054 (“SVB”), as agent (the “Agent”), and the Lenders listed on Schedule 1.1 and otherwise party hereto, including without limitation, SVB and GOLD HILL VENTURE LENDING 03, L.P. (“Gold Hill”) and CAVIUM NETWORKS, a California corporation, whose address is 805 E. Middlefield Road, Mountain View, California 94043 (“Borrower”) provides the terms on which Lenders shall extend credit to Borrower and Borrower shall repay Lenders. 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. The term “financial statements” includes the notes and schedules attached hereto. The terms “including” and “includes” always mean “including (or includes) without limitation,” in this or any Loan Document. Capitalized terms in this Agreement shall have the meanings set forth in Article 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.

     Borrower hereby unconditionally promises to pay Lenders the unpaid principal amount of all Credit Extensions and interest on the unpaid principal amount of the Credit Extensions as and when due in accordance with this Agreement.

          2.1.1 Term Loan Facility.

          (a) Availability. Subject to the terms and conditions of this Agreement, Lenders agree, severally and not jointly, to lend to Borrower from time to time prior to the Commitment Termination Date, advances (each an “Advance” and collectively the “Advances”) in an aggregate amount not to exceed the Term Loan, according to each Lender’s pro rata share of the Term Loan (based upon the respective Commitment Percentage of each Lender). When repaid, the Advances may not be re-borrowed. Lenders’ obligation to lend hereunder shall terminate on the earlier of (i) the occurrence and continuance of an Event of Default, or (ii) the Commitment Termination Date. For purposes of this Section, the minimum amount of each Advance is One Million Dollars ($1,000,000.00).

          (b) Borrowing Procedure. To obtain an Advance, Borrower must notify Agent by facsimile or telephone by 12:00 p.m. Pacific time five (5) Business Days prior to the date the Advance is to be made. If such notification is by telephone, Borrower must promptly confirm the notification by delivering to Agent a completed Payment/Advance Form in the form attached as Exhibit B ( the Payment/Advance Form). On the Funding Date, each Lender shall credit and/or transfer (as applicable) to Borrower’s deposit account, an amount equal to its Commitment Percentage multiplied by the amount of the Advance. Each Lender may make Advances under this Agreement based on instructions from a Responsible Officer or his or her designee or without instructions if the Advances are necessary to meet Obligations which have become due. Each Lender may rely on any telephone notice given by a person whom such Lender reasonably believes is a Responsible Officer or designee. Borrower shall indemnify each Lender for any loss Lender suffers due to such reliance.

     2.2 Termination of Commitment to Lend.

     Each Lender’s obligation to lend the undisbursed portion of the Obligations shall terminate if, in such Lender’s good faith business judgment, there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the prospect of repayment of the Obligations, or there has

been any material adverse deviation by Borrower from the most recent business plan of Borrower presented to and accepted by Agent prior to the execution of this Agreement.

     2.3 Interest Rate, Payments.

          (a) Interest Payments. Commencing on the first Payment Date of the month following the month in which the Funding Date occurs (or commencing on the Funding Date if the Funding Date is the first calendar day of the month), Borrower shall make monthly payments of interest at the rate set forth in Section 2.3(c).

          (b) Repayment. Commencing on the Term Loan Amortization date, for each Advance, Borrower shall make consecutive equal monthly payments of principal and interest, in advance, calculated by Agent based upon: (1) the amount of the Advance, (2) the effective rate of interest set forth in Section 2.3(c), and (3) an amortization schedule equal to thirty (30) months (individually, the “ Scheduled Payment”, and collectively, “Scheduled Payments”), on the first Business Day of the month following the month in which the Funding Date occurs (or commencing on the Funding Date if the Funding Date is the first Business Day of the month) with respect to such Advance and continuing thereafter during the Repayment Period on the first Business Day of each successive calendar month (each a “Payment Date”). All unpaid principal and accrued interest is due and payable in full on the last Payment Date with respect to such Advance. Payments received after 12:00 noon Pacific time are considered received at the opening of business on the next Business Day. An Advance may only be prepaid in accordance with Sections 2.3(e) and 2.3(f).

          (c) Interest Rate. Borrower shall pay interest on each Payment Date on the unpaid principal amount of each Advance until the Advance has been paid in full, at the fixed per annum rate of interest equal to the aggregate of the Prime Rate and three and three-quarters of one percent (3.75%), determined by Agent as of the Funding Date for each Advance. Interest is computed on the basis of a three hundred sixty (360) day year for the actual number of days elapsed. Any amounts outstanding during the continuance of an Event of Default shall bear interest at a per annum rate equal to the applicable rate as set forth above, plus four percent (4%)(the “Default Rate”).

          (d) Final Payment. On the Maturity Date with respect to each Advance, Borrower shall pay, in addition to the unpaid principal and accrued interest and all other amounts due on such date with respect to such Advance, an amount equal to the Final Payment.

          (e) Mandatory Prepayment Upon an Acceleration. If the Advances are accelerated following the occurrence of an Event of Default or otherwise, Borrower shall immediately pay to Lenders an amount equal to the sum of: (i) all outstanding principal plus accrued interest, (ii) the Final Payment plus (iii) all other sums including the Prepayment Fee, if any, that shall have become due and payable, including interest at the Default Rate with respect to any past due amounts.

          (f) Permitted Prepayment of Loans. Borrower shall have the option to prepay all, but not less than all, of the Advances advanced by Lenders under this Agreement, provided Borrower (i) provides written notice to Agent of its election to prepay the Advances at least thirty (30) days prior to such prepayment, and (ii) pays, on the date of such prepayment (A) all outstanding principal plus accrued interest, (B) the Final Payment plus (C) all other sums including the Prepayment Fee, if any, that shall have become due and payable, including interest at the Default Rate with respect to any past due amounts.

          (g) Debit of Accounts. Agent may debit any of Borrower’s deposit or operating accounts including Account Number 3300301459 for principal and interest payments when due or any amounts Borrower owes Lenders, when due. Agent shall promptly notify Borrower after it debits Borrower’s accounts. These debits shall not constitute a set-off.

     2.4 Fees.

     Borrower shall pay to Agent:

          (a) Final Payment. The Final Payment, when due hereunder;

          (b) Prepayment Fee. The Prepayment Fee, as defined herein, if and when applicable; and

          (c) Lenders’ Expenses. All Lenders’ Expenses (including reasonable attorneys’ fees and expenses) incurred through and after the Closing Date, when due.

     2.5 Additional Costs. If any new law or regulation adopted after the Closing Date increases any Lender’s costs or reduces its income for any Credit Extension made hereunder, Borrower shall pay the increase in cost or reduction in income or additional expense; provided, however, that Borrower shall not be liable for any amount attributable to any period before 180 days prior to the date Agent notifies Borrower of such increased costs. Each Lender agrees that it shall allocate any increased costs among its customers similarly affected in good faith and in a manner consistent with such Lender’s customary practice.

3 CONDITIONS OF LOANS

     3.1 Conditions Precedent to Initial Credit Extension.

     The Lenders’ obligation to make the initial Credit Extension is subject to the condition precedent that Agent shall have received, in form and substance satisfactory to Agent, such documents and completion of such other matters, as Agent may reasonably deem necessary or appropriate, including, without limitation, the following:

          (a) this Agreement;

          (b) a certificate of the Secretary of Borrower with respect to articles, by-laws, incumbency and resolutions authorizing the execution and delivery of this Agreement, the Loan Documents, and all transactions related thereto, including the Warrant;

          (c) subordination agreements, as necessary;

          (d) landlord’s waiver;

          (a) timely receipt of any Payment/Advance Form; and

          (b) the representations and warranties in Article 5 shall be true in all material respects on the date of the Payment/Advance Form and on the effective date of each Credit Extension and no Event of Default shall have occurred and be continuing, or result from the Credit Extension (except to the extent they relate specifically to an earlier date, in which case such representations and warranties shall continue to have been true and accurate as of such date specified). Each Credit Extension is Borrower’s representation and warranty on that date that the representations and warranties in Article 5 remain true in all material respects.

4 CREATION OF SECURITY INTEREST

     4.1 Grant of Security Interest. Borrower hereby grants Agent, for the ratable benefit of the Lenders, and to each Lender, to secure the payment and performance in full of all of the Obligations and the performance of each of Borrower’s duties under the Loan Documents, a continuing security interest in, and pledges and assigns to Agent, for the ratable benefit of the Lenders, and to each Lender, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Subject to Section 5.2, Borrower warrants and represents that the security interest granted herein shall be a first priority security interest in the Collateral.

Except as noted on the Representations and Warranties Certificate, Borrower is not a party to, nor is it bound by, any material license (other than over the counter software that is commercially available to the public) or other material agreement with respect to which Borrower is the licensee that is material to Borrower’s business that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property. Borrower shall provide written notice to Agent within fifteen (15) days of entering or becoming bound by, any such license or agreement which is reasonably likely to have a material impact on Borrower’s business or financial condition. Borrower shall take such steps as Agent reasonably requests to obtain the consent of, authorization by or waiver by, any person whose consent or waiver is necessary for all such licenses or contract rights to be deemed “Collateral” and for Lenders to have a security interest in it that might otherwise be restricted or prohibited by law or by the terms of any such license or agreement, whether now existing or entered into in the future.

If Borrower shall, at any time, acquire a commercial tort claim, Borrower shall promptly notify Agent in a writing signed by Borrower of the brief details thereof and grant to Agent and Lenders 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 satisfactory to Agent.

     4.2 Termination by Borrower.

     Borrower may terminate this agreement by sending written notice to Agent and paying in full all Obligations. If this Agreement is terminated, Lenders’ and Agent’s lien and security interest in the Collateral shall continue until Borrower fully satisfies the Obligations, other than any inchoate obligations to indemnify Bank. Upon that satisfaction, Bank will terminate its security interest in the Collateral.

     4.3 Authorization to File Financing Statements.

     Borrower hereby authorizes Agent to file UCC financing statements, without notice to Borrower, with all appropriate jurisdictions, in order to perfect or protect Agent’s and Lenders’ interest or rights hereunder, including a notice that any disposition of the Collateral by either Borrower or any other Person, shall be deemed to violate the rights of the Lenders under the Code.

5 REPRESENTATIONS AND WARRANTIES

     Borrower represents and warrants to Agent and each Lender as follows:

     5.1 Due Organization and Authorization.

     Borrower and each Subsidiary is duly existing and in good standing in its state of formation and qualified and licensed to do business in, and in good standing in, any state in which the conduct of its business or its ownership of property requires that it be qualified, except where the failure to do so could not reasonably be expected to have a material adverse effect on Borrower’s business or operations. In connection with this Agreement, Borrower delivered to Agent and Lenders a representations and warranties certificate signed by Borrower and entitled “Representations and Warranties Certificate” (the “Representations and Warranties Certificate”). Borrower represents and warrants to Agent and each Lender that: (a) Borrower’s exact legal name is that indicated on the Representations and Warranties Certificate and on the signature page hereof; and (b) Borrower is an organization of the type, and is organized in the jurisdiction, set forth in the Representations and Warranties Certificate; and (c) the Representations and Warranties Certificate accurately sets forth Borrower’s organizational identification number or accurately states that Borrower has none; and (d) the Representations and Warranties Certificate accurately sets forth Borrower’s place of business, or, if more than one, its chief executive office as well as Borrower’s mailing address if different, and (e) all other information set forth on the Representations and Warranties Certificate pertaining to Borrower is accurate and complete in all material respects. If Borrower does not now have an organizational identification number, but later obtains one, Borrower shall forthwith notify Agent of such organizational identification number.

     The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with Borrower’s organizational documents, nor shall they constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which or by which it is bound in which the default could reasonably be expected to have a material adverse effect on Borrower’s business or operations.

     5.2 Collateral.

     Borrower has good title to the Collateral, free of Liens except Permitted Liens. Borrower has no deposit account, other than the deposit accounts with Lenders and deposit accounts described in the Representations and Warranties Certificate delivered to Agent and Lenders in connection herewith. The Collateral is not in the possession of any third party bailee (such as a warehouse). Except as hereafter disclosed to the Lenders in writing by Borrower, none of the components of the Collateral shall be maintained at locations other than as provided in the Representations and Warranties Certificate. In the event that Borrower, after the date hereof, intends to store or otherwise deliver any portion of the Collateral to a bailee, then Borrower will notify Agent in writing and, except with respect to warehouse locations of Borrower at which Collateral with an aggregate value of $500,000 or less is located with respect to all such locations, receive the written consent of Lenders and such bailee must acknowledge in writing that the bailee is holding such Collateral for the benefit of Agent and Lenders. All Inventory is in all material respects of good and marketable quality, free from material defects. Borrower is the sole owner of the Intellectual Property, except for non-exclusive licenses granted to its customers in the ordinary course of business. To the best of Borrower’s knowledge, 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 no claim has been made that any part of the Intellectual Property violates the rights of any third party, except to the extent such invalidity, unenforceability or claim could not reasonably be expected to have a material adverse effect on Borrower’s business or operations.

     5.3 Litigation.

     Except as shown in the Representations and Warranties Certificate, there are no actions or proceedings pending or, to the knowledge of Borrower’s Responsible Officers, threatened by or against Borrower or any Subsidiary in which an adverse decision could reasonably be expected to have a material adverse effect on Borrower’s business or operations.

     5.4 No Material Deterioration in Financial Statements.

     All consolidated financial statements for Borrower, and any Subsidiary, delivered to Agent, fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations. There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Agent.

     5.5 Solvency.

     The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature.

     5.6 Regulatory Compliance.

     Borrower is not an “investment company” or a company “controlled” by an “investment company” under the Investment Company Act of 1940. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations X, T and U of the Federal Reserve Board of Governors). Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to have a material adverse effect on Borrower’s business or operations. None of Borrower’s or any Subsidiary’s properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Borrower and each Subsidiary has timely filed all required tax returns and paid, or made adequate provision to pay, all material taxes, except those being contested in good faith with adequate reserves under GAAP. Borrower and each Subsidiary has 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, except where the failure to obtain or make such consents, declarations, notices or filings would not reasonably be expected to have a material adverse effect on Borrower’s business or operations.

     5.7 Subsidiaries.

     Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments.

     5.8 Full Disclosure.

     No written representation, warranty or other statement of Borrower in any certificate or written statement given to Agent or any Lender (taken together with all such written certificates and written statements given to Agent or any Lender) 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 in light of the circumstance under which they were made, it being recognized by Agent that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not to be 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

     Borrower shall do all of the following:

     6.1 Government Compliance.

     Borrower shall maintain its and all 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 Borrower’s business or operations. Borrower shall comply, and have each Subsidiary comply, with all laws, ordinances and regulations to which it is subject, noncompliance with which could have a material adverse effect on Borrower’s business or operations.

     6.2 Financial Statements, Reports, Certificates.

     6.5 Insurance.

     Borrower shall keep its business and the Collateral insured for risks and in amounts, and as Lenders and Agent may reasonably request. Insurance policies shall be in a form, with companies, and in amounts that are satisfactory to Lenders and Agent and customary for businesses in Borrower’s industry which are similarly situated. All property policies shall have a lender’s loss payable endorsement showing each Lender as an additional loss payee and all liability policies shall show the Lenders and Agent as an additional insured and all policies shall provide that the insurer must give Agent on behalf of Lenders at least twenty (20) days notice before canceling its policy. At Agent’s request, Borrower shall deliver certified copies of policies and evidence of all premium payments. Proceeds payable under any policy shall, at Agent’s option, be payable to Agent on behalf of Lenders on account of the Obligations. Notwithstanding the foregoing, 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 up to One Hundred Thousand Dollars ($100,000.00), in the aggregate, toward the replacement or repair of destroyed or damaged property; provided that (i) any such replaced or repaired property (a) shall be of equal or like value as the replaced or repaired Collateral and (b) shall be deemed Collateral in which Lenders have been granted a first priority security interest and (ii) after the occurrence and during the continuation of an Event of Default all proceeds payable under such casualty policy shall, at the option of Agent, be payable to Agent, for the ratable benefit of the Lenders, on account of the Obligations. If Borrower fails to obtain insurance as required under Section 6.5 or to pay any amount or furnish any required proof of payment to third persons and Agent, Agent may make all or part of such payment or obtain such insurance policies required in Section 6.5, and take any action under the policies Agent deems prudent.

          (b) Borrower shall identify to Agent, in writing, any bank or securities account opened by Borrower with any institution other than Agent. In addition, for each such account that Borrower or Guarantor at any time opens or maintains, Borrower shall, at Agent’s request and option, pursuant to an agreement in form and substance reasonably acceptable to the Lenders and Agent, cause the depository bank or securities intermediary to agree that such account is the collateral of Agent, and enter into a “control agreement” on behalf of Lenders pursuant to the terms hereunder.

          (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 Agent and/or Lenders);

          (b) Stop advancing money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Agent and/or Lenders;

          (c) Settle or adjust disputes and claims directly with account debtors for amounts, on terms and in any order that Agent considers advisable, and notify any Person owing Borrower money of Agent’s, and Lenders’ security interest in such funds and verify and/or collect the amounts owed by such account debtor. After the occurrence of an Event of Default, any amounts received by Borrower shall be held in trust by Borrower for Agent, and, if requested by Agent, Borrower shall immediately deliver such receipts to Agent in the form received from the account debtor, with proper endorsements for deposit;

          (d) Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower shall assemble the Collateral if Agent requests and make it available as Agent designates. Agent 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. Borrower grants Agent for the benefit of Lenders a license to enter and occupy any of its premises, without charge, to exercise any of Agent’s rights or remedies;

          (e) Apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Agent or Lenders owing to or for the credit or the account of Borrower;

          (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Agent is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, 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

          (g) Place a “hold” on any account maintained with Agent or Lenders 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; and

          (h) Exercise all rights and remedies and dispose of the Collateral according to the Code.

     9.2 Power of Attorney.

     Borrower hereby irrevocably appoints Agent as its lawful attorney-in-fact, to be effective upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s name on any checks or other forms of payment or security; (b) sign 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 Agent determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; and (e) transfer the Collateral into the name of Agent for the benefit of Lenders or a third party as the Code permits. Borrower hereby appoints Agent as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations have been satisfied in full and Agent and Lenders are under no further obligation to make Credit Extensions hereunder. Agent’s foregoing appointment as Borrower’s attorney in fact, and all of Agent’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Lenders’ and Agent’s obligation to provide Credit Extensions terminates.

     9.3 Lenders’ Expenses

     Any amounts paid by Lenders as provided herein shall constitute Lenders’ Expenses and are immediately due and payable, and shall bear interest at the then applicable rate hereunder and be secured by the Collateral. No payments by Lenders shall be deemed an agreement to make similar payments in the future or Agent’s and Lenders’ waiver of any Event of Default.

     9.4 Agent’s and Lenders’ Liability for Collateral.

     So long as Agent and Lenders comply with reasonable banking practices regarding the safekeeping of Collateral and Section 9-207 of the Code, Agent and Lenders 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. Borrower bears all risk of loss, damage or destruction of the Collateral.

     9.5 Remedies Cumulative.

     Agent’s rights and remedies under this Agreement, the Loan Documents, and all other agreements are cumulative. Agent has all rights and remedies provided under the Code, by law, or in equity. Agent’s exercise of one right or remedy is not an election, and Agent’s waiver of any Event of Default is not a continuing waiver. Agent’s delay is not a waiver, election, or acquiescence. No waiver hereunder shall be effective unless signed by Agent and each Lender and then is only effective for the specific instance and purpose for which it was given.

     9.6 Demand Waiver.

     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 Agent on which Borrower is liable.
