THIS LOAN AND SECURITY AGREEMENT, dated as of December 31, 2002, is by and between SILICON VALLEY BANK (“Bank”), whose address is 3003 Tasman Drive, Santa Clara, California, 95054, and LEGATO SYSTEMS, INC. (“Borrower”), whose address is 2350 West El Camino Real, Mountain View, California, 94040, and provides the terms on which Bank will lend to Borrower and Borrower will repay Bank. The parties hereto agree as follows:

1. DEFINITIONS; ACCOUNTING AND OTHER TERMS

Capitalized terms used herein shall have the meanings given to such terms in Section 13 of this Agreement. Accounting terms not defined in this Agreement will be construed following GAAP. Calculations and determinations must be made following GAAP. The term “financial statements” includes the notes and schedules thereto. The terms “including” and “includes” always mean “including (or includes) without limitation,” in this or any Loan Document.

2. LOAN AND TERMS OF PAYMENT

2.1 Promise to Pay.

Borrower promises to pay Bank the unpaid principal amount of all Advances and interest on the unpaid principal amount of the Advances.

2.1.1 Advances.

(a) Bank will make Advances not exceeding the lesser of (i) the Committed Revolving Line or (ii) the Borrowing Base minus (A) the outstanding principal balance of the Advances minus (B) the amount of all outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit) minus (C) the FX Reserve and minus (D) all amounts for services utilized for Cash Management Services. Amounts borrowed hereunder that remain available for borrowing under this Agreement may be repaid and reborrowed prior to the Maturity Date.

(b) To obtain an Advance, Borrower must notify Bank by facsimile or telephone by 12:00 noon Pacific Time on the Business Day the Advance is to be made. Borrower must promptly confirm the notification by delivering to Bank the Loan Payment/Advance Request Form attached as Exhibit B (the “Payment/Advance Form”). Bank will credit Advances to Borrower’s deposit account. Bank 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. Bank may rely on any telephone notice given by a person whom Bank believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due to such reliance.

(c) The Committed Revolving Line shall terminate on the Maturity Date, and all Advances are immediately due and payable on the Maturity Date.

(d) Bank’s obligation to lend the undisbursed portion of the Obligations will terminate if, in Bank’s sole discretion, 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 Bank prior to the execution of this Agreement.

2.1.2 Letters of Credit.

(a) Bank will issue or have issued standby Letters of Credit for Borrower’s account not exceeding the lesser of (a) the amount available under the Committed Revolving Line and (b) the Borrowing Base (each, a “Letter of Credit”). Each Letter of Credit will have an expiry date of no later than 180 days after the Maturity Date, but Borrower’s reimbursement obligation will be secured by cash on terms acceptable to Bank at any time after the Maturity Date if such Maturity Date is not extended by Bank or if an Event of Default occurs and continues. Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request.

(b) Prior to or simultaneously with the opening of each Letter of Credit, Borrower shall pay to Bank Bank’s customary fees in connection with the opening of a letter of credit (the “Letter of Credit Fees”). The Letter of Credit Fees shall be paid upon the opening of each Letter of Credit and upon each anniversary thereof, if required. In addition, Borrower shall pay to Bank, for its own account, any and all additional issuance, negotiation, processing, transfer or other fees to the extent and as and when required by the provisions of any application for Letters of Credit. All Letter of Credit Fees shall be part of the Obligations.

(c) If any Letter of Credit is drawn upon, such amount shall constitute an Advance but shall be immediately due and payable. If such amount is not paid immediately, then the full amount thereof shall accrue interest at the rate set forth in Section 2.3(a).

2.1.3 Foreign Exchange.

If there is availability under the lesser of the Committed Revolving Line and the Borrowing Base, then Borrower may enter into foreign exchange forward contracts with the Bank under which Borrower commits to purchase from or sell to Bank a set amount of foreign currency more than one Business Day after the contract date (the “FX Forward Contract”). Bank will subtract ten percent (10%) of each outstanding FX Forward Contract from the amount available under the Committed Revolving Line (the “FX Reserve”). Bank may terminate the FX Forward Contracts if an Event of Default occurs.

2.1.4 Cash Management Services.

Borrower may use the availability under the lesser of the Committed Revolving Line and the Borrowing Base for Bank’s Cash Management Services, which may include merchant services, direct deposit of payroll, business credit cards, automated clearing house transactions, controlled disbursement accounts and check cashing services identified in various cash management services agreements related to such services (the “Cash Management Services”). Such aggregate amounts utilized for Cash Management Services will at all times reduce the amount otherwise available to be borrowed under the Committed Revolving Line. Any amounts Bank pays on behalf of Borrower or any amounts that are not paid by Borrower for

2.

any Cash Management Services will be treated as Advances under the Committed Revolving Line and will accrue interest at the rate for Advances.

2.2 Overadvances.

If, at any time, Borrower’s Obligations hereunder exceed the lesser of (a) the Committed Revolving Line or (b) the Borrowing Base, Borrower shall immediately pay Bank the excess.

2.3 Interest Rate, Payments.

(a) Interest Rate. Advances accrue interest on the outstanding principal balance thereof at a per annum rate equal to the greater of (i) one-half of one percentage point above the Prime Rate and (ii) 4.75%. After an Event of Default has occurred, Obligations shall accrue interest at a rate per annum equal to 3 percent above the rate effective immediately before the Event of Default. The interest rate increases or decreases when the Prime Rate changes. Interest is computed on a 360 day year for the actual number of days elapsed.

(b) Payments. Interest due on the Advances is payable on the first (1^st) of each month. Bank may debit any of Borrower’s deposit accounts, including account number 3300385582, for principal and interest payments owing or any amounts Borrower owes Bank. Bank will promptly notify Borrower when it debits Borrower’s accounts. These debits are not a set-off. Payments received after 1:00 PM 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 accrue.

2.4 Fees.

Borrower will pay:

(a) Loan Fee. A fully earned, non-refundable loan fee in the amount of Fifty Thousand Dollars ($50,000) is due on or before the Closing Date.

(b) Expedite Fee. A fully earned, non-refundable fee in the amount of Ten Thousand Dollars ($10,000) is due on or before the Closing Date, but only if the Closing Date occurs on or before December 31, 2002.

(c) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses) incurred through and after the date of this Agreement are payable upon demand.

All of Borrower’s deposit accounts are described on the Schedule. The Accounts are bona fide, existing obligations, and the service or property has been performed or delivered to the account debtor or its agent for immediate shipment to and unconditional acceptance by the account debtor. The Collateral is not in the possession of any third party bailee (such as at a warehouse).

Borrower has no notice of any actual or imminent Insolvency Proceeding of any account debtor whose accounts are an Eligible Account in any Borrowing Base Certificate. 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 and exclusive licenses granted to its customers in the ordinary course of business. Each issued Patent owned by Borrower 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 claim could not reasonably be expected to cause a Material Adverse Change. Borrower shall not change the location of any Collateral.

5.3 Litigation.

Except as shown in the Schedule, 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 a likely adverse decision could reasonably be expected to cause a Material Adverse Change.

9.1 Rights and Remedies.

When 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 Borrower’s benefit 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, on terms and in any order that Bank considers advisable;

                (d) Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower will assemble the Collateral if Bank requires 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,

12.

purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies;

(e) Apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank 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. Bank is 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 completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; and

(g) Dispose of the Collateral according to the Code.

9.2 Power of Attorney.

Effective only when an Event of Default occurs and continues, Borrower irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower’s name on any checks or other forms of payment or security; (ii) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against account debtors, (iii) make, settle, and adjust all claims under Borrower’s insurance policies; (iv) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits. Bank may exercise the power of attorney to sign 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. Bank’s appointment as Borrower’s 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 Advances terminates.

9.3 Accounts Collection.

When an Event of Default occurs and continues, Bank may notify any Person owing Borrower money of Bank’s security interest in the funds and verify the amount of the Account. Borrower must collect all payments in trust for Bank and, if requested by Bank, immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit.

9.4 Bank Expenses.

If Borrower fails to pay any amount or furnish any required proof of payment to third persons, Bank may make all or part of the payment or obtain insurance policies required in Section 6.5, and take any action under the policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then

13.

applicable rate and secured by the Collateral. 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 Bank’s Liability for Collateral.

If Bank complies with reasonable banking practices and the Code, it is not liable 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.

9.6 Remedies Cumulative.

Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements 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 is not a waiver, election, or acquiescence. No waiver is effective unless signed by Bank and then is only effective for the specific instance and purpose for which it was given.

9.7 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 Bank on which Borrower is liable.

10. NOTICES

3.0 Responsibilities

The Chief Financial Officer and/or Corporate Controller are authorized to make cash investments on behalf of the Company and are charged with the responsibility of creating and maintaining an investment portfolio that adheres to the guidelines set forth in this policy. Any revisions or amendments to parameters set forth herein will be the responsibility of the Chief Financial Officer.

EXHIBIT E

FORM OF OPINION OF COUNSEL TO BORROWER

[Date]

Silicon Valley Bank

2400 Geng Road, Suite 200

Palo Alto, California 94303

Re:                                                  

Ladies and Gentlemen:

We have acted as [special] counsel for [                                         ], a Delaware corporation (the “Company”), in connection with [brief description of transaction] and the Loan and Security Agreement dated as of [                                ] (the “Agreement”), by and between the Company and Silicon Valley Bank (the “Lender”).

This opinion is furnished to you pursuant to Section          of the Agreement. Capitalized terms used but not defined herein have the meanings given them in the Agreement.

In connection with this opinion, we have examined the following documents, each of which is dated as of even date herewith:

1. the Agreement; and

2. the Negative Pledge Agreement by and between the Company and the Lender.

In addition, for purposes of rendering our opinions below, we have examined the following:

3. the Certificate of Incorporation of the Company as certified by the Secretary of State of the State of Delaware on                                 ;

4. the Bylaws of the Company certified to us by an officer of the Company to be in full force and effect as of the date of this opinion letter;

5. the resolutions adopted by the board of directors of the Company at a meeting held on                                 ;

6. the Certificate of Status issued by the Secretary of State of the State of Delaware stating that the Company is a domestic corporation in good standing in such state, dated                                 ; and

7. the certificate of tax good standing for the Company issued by the Franchise Tax Board of the State of California on                                 .

Items (1) and (2) above are hereinafter collectively referred to as the “Transaction Documents”; items (3) and (4) above are hereinafter collectively referred to as the “Organizational Documents”; and items (6) and (7) above are hereafter referred to as the “Good Standing Certificates.”

We have examined executed counterparts of the Transaction Documents and originals, or copies, the authenticity of which has been established to our satisfaction, of such other documents, corporate records, agreements and instruments and certificates of public officials and officers of the Company as we have deemed necessary as the basis for the opinions herein expressed. As to the questions of fact material to such opinions we have, when relevant facts were not independently established, relied upon certifications by officers of the Company.

Based on the foregoing and having regard for legal considerations as we have deemed relevant, it is our opinion that:

1. The Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of Delaware and is qualified as a foreign corporation in all jurisdictions where the failure to do so would result in a material adverse effect upon the Company.

2. The execution and delivery of each Transaction Document and performance by the Company of its obligations thereunder and of the transactions contemplated thereby, are within the corporate power and authority of the Company and have been authorized by proper corporate proceedings. The Transaction Documents have been duly executed and delivered by the Company.

3. Each of the Transaction Documents and all of the terms and provisions thereof are the legal, valid and binding obligations of the Company, enforceable in accordance with their respective terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors’ rights generally and by general principles of equity including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law.

4. The execution and delivery of, and performance of its obligations under, each of the Transaction Documents by the Company do not (a) violate any provision of the Organizational Documents, (b) conflict with or constitute a default under any credit agreement, loan agreement, or any other agreement evidencing an obligation by the Company to repay any indebtedness, or (c) breach or otherwise violate any existing obligation of the Company under any order, writ, injunction judgment or decree of any state or federal court or governmental authority binding on the Company.

This Opinion is furnished by [us] [the undersigned] as counsel for the Company and may be relied upon by you only in connection with the transactions contemplated by the Agreement. It may not be used or relied upon by you or for any other purpose or by any other person, nor may copies be delivered to any other person, without in each instance [our] [the undersigned’s] prior written consent. You may, however deliver a copy of this opinion to each permitted

2.

transferee and assignee of the Agreement, together with your and their participants, and each such transferee, assignee and participant may rely on this opinion as if it were addressed and had been delivered to it on the date of this opinion.

Respectfully submitted,
