2.1 Promise to Pay.

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

2.1.1 Revolving Advances.

(a) Bank will make Advances not exceeding the lesser of (i) the Committed Revolving Line minus all amounts for services utilized under the Cash Management Services Sublimit or (ii) the Borrowing Base, it being understood that the Cash Management Services Sublimit will be available without respect to the amount of the Borrowing Base. Amounts borrowed under this Section may be repaid and reborrowed during the term of this Agreement. All advances shall be evidenced by the Revolving Promissory Note to be executed and delivered by Borrower to Bank on the Closing Date and shall be repaid in accordance with the terms of the Revolving Promissory Note.

(b) To obtain an Advance, Borrower must notify Bank by facsimile or telephone by 3:00 p.m. Eastern time on the Business Day the Advance is to be made. Borrower must promptly confirm the notification by delivering to Bank the 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 reasonably believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due to such reliance.

(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.

FOR VALUE RECEIVED, the undersigned, SOURCEFIRE, INC., a Delaware corporation (“Borrower”) promises to pay to the order of SILICON VALLEY BANK, a California-chartered bank, doing business in Virginia as “Silicon Valley East, Inc.” (“Bank”), at such place as the holder hereof may designate, in lawful money of the United States of America, the aggregate unpaid principal amount of all equipment advances (“Equipment Advances”) made by Bank to Borrower in accordance with the terms and conditions of the Loan and Security Agreement between Borrower and Bank of even date herewith, (as amended from time to time the “Loan Agreement”), up to a maximum principal amount of One Million and no/100 Dollars ($1,000,000.00) (“Principal Sum”), or so much thereof as may be advanced and remains unpaid. Borrower may request Equipment Advances under this Note from and until the Equipment Availability End Date. The unpaid Principal Sum, together with interest thereon at the rate or rates provided in the Loan Agreement, shall be payable as set forth in the Loan Agreement.

Borrower further agrees that, if any payment made by Borrower or any other person is applied to this Note and is at any time annulled, set aside, rescinded, invalidated, declared to be fraudulent or preferential or otherwise required to be refunded or repaid, or the proceeds of any property hereafter securing this Note is required to be returned by Bank to Borrower, its estate, trustee, receiver or any other party, including, without limitation, such Borrower, under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, Borrower’s liability hereunder (and any lien, security interest or other collateral securing such liability) shall be and remain in full force and effect, as fully as if such payment had never been made, or, if prior thereto any such lien, security interest or other collateral hereafter securing Borrower’s liability hereunder shall have been released or terminated by virtue of such cancellation or surrender, this Note (and such lien, security interest or other collateral) shall be reinstated in full force and effect, and such prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect the obligations of Borrower in respect of the amount of such payment (or any lien, security interest or other collateral securing such obligation).

This Note is the “Equipment Term Note” described in the Loan Agreement, to which reference is hereby made for a more complete statement of the terms and conditions under which the loans and advances evidenced hereby are made. This Note is secured as provided in the Loan Agreement. All

Borrower irrevocably waives the right to direct the application of any and all payments at any time hereafter received by Bank from or on behalf of Borrower and Borrower irrevocably agrees that Bank shall have the continuing exclusive right to apply any and all such payments against the then due and owing obligations of Borrower as Bank may deem advisable. In the absence of a specific determination by Bank with respect thereto, all payments shall be applied in the following order: (a) then due and payable fees and expenses; (b) then due and payable interest payments and mandatory prepayments; and (c) then due and payable principal payments and optional prepayments.

Bank is hereby authorized by Borrower to endorse on Bank’s books and records each Advance made by Bank under this Note and the amount of each payment or prepayment of principal of each such Advance received by Bank; it being understood, however, that failure to make any such endorsement (or any error in notation) shall not affect the obligations of Borrower with respect to Advances made hereunder, and payments of principal by Borrower shall be credited to Borrower notwithstanding the failure to make a notation (or any errors in notation) thereof on such books and records.

The occurrence of any Event of Default under the Loan Agreement, shall constitute an Event of Default under the terms of this Note.

Upon the occurrence of an Event of Default, the Bank may at its option, exercise all of the rights, powers, and remedies available under the terms of this Note or any of the other Loan Documents and all applicable laws. Borrower and all endorsers, guarantors, and other parties who may now or in the future be primarily or secondarily liable for the payment of the indebtedness evidenced by this Note hereby severally waive presentment, protest and demand, notice of protest, notice of demand and of dishonor and non-payment of this Note and expressly agree that this Note or any payment hereunder may be extended from time to time without in any way affecting the liability of Borrower, guarantors and endorsers.

In the event this Note is not paid when due or any installment due hereunder is not paid within fifteen (15) days of the date when due, whether by maturity or acceleration, Borrower hereby appoints and designates Xxxx Xxxxxxx, Esq., Borrower’s duly constituted attorney-in-fact to confess judgment pursuant to the provisions of Section 8.01-432 of the Code of Virginia of 1950, as amended, against Borrower for all principal of and interest due and payable under this Note upon the occurrence of an Event of Default, together with attorneys’ fees and collection fees as provided herein (to the extent permitted by law), which judgment shall be confessed in the Clerk’s Office of the Circuit Court of Fairfax County, Virginia. Upon request of Bank, Borrower will execute an amendment or other agreement substituting attomeys-in-fact appointed to act for Borrower hereunder.

Borrower promises to pay all costs and expense of collection of this Note and to pay all reasonable attorneys’ fees incurred in such collection, whether or not there is a suit or action, or in any suit or action to collect this Note or in any appeal thereof. No delay by Bank in exercising any power or right hereunder shall operate as a waiver of any power or right. Time is of the essence as to all obligations hereunder.

This Note is issued pursuant to the Loan Agreement, which shall govern the rights and obligations of Borrower with respect to all obligations hereunder.

Borrower acknowledges and agrees that this Note shall be governed by the laws of the Commonwealth of Virginia, excluding conflicts of laws principles, even though for the convenience and at the request of Borrower, this Note may be executed elsewhere.

BORROWER ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE COMMONWEALTH OF VIRGINIA IN ANY ACTION, SUIT, OR PROCEEDING OF ANY KIND, AGAINST IT WHICH ARISES OUT OF OR BY REASON OF THIS AGREEMENT; PROVIDED, HOWEVER, THAT IF FOR ANY REASON BANK CANNOT AVAIL ITSELF OF THE COURTS OF VIRGINIA, BORROWER ACCEPTS JURISDICTION OF THE COURTS AND VENUE IN SANTA XXXXX COUNTY, CALIFORNIA.

WARRANT TO PURCHASE STOCK

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND, EXCEPT AND PURSUANT TO THE PROVISIONS OF ARTICLE 5 BELOW, MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAW OR, IN THE OPINION OF LEGAL COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE SECURITES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS EXEMPT FROM REGISTRATION.

WARRANT TO PURCHASE STOCK


Company:		SourceFire, Inc., a Delaware corporation
Number of Shares:		5,246
Class of Stock:		Series A Convertible Preferred
Warrant Price:		$3.05 per share
Issue Date:		November 3, 2003
Expiration Date:		November 2, 2010

THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for other good and valuable consideration, SILICON VALLEY BANK (“Holder”) is entitled to purchase the number of fully paid and nonassessable shares of the class of securities (the “Shares”) of the company (the “Company”) at the Warrant Price, all as set forth above and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant.

ARTICLE 1. EXERCISE.

1.1 Method of Exercise. Holder may exercise this Warrant by delivering a duly executed Notice of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company. Unless Holder is exercising the conversion right set forth in Article 1.2, Holder shall also deliver to the Company a check, wire transfer (to an account designated by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares being purchased.

1.2 Conversion Right. In lieu of exercising this Warrant as specified in Article 1.1, Holder may from time to time convert this Warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of the Shares or other securities otherwise issuable upon exercise of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair market value of one Share. The fair market value of the Shares shall be determined pursuant to Article 1.3.

1.3 Fair Market Value. If the Company’s common stock is traded in a public market and the shares are common stock, the fair market value of each Share shall be the closing price of a Share reported for the business day immediately before Holder delivers its Notice of Exercise to the Company (or in the instance where the Warrant is exercised immediately prior to the effectiveness of the Company’s initial public offering, the “price to public” per share price specified in the final prospectus

relating to such offering). If the Company’s common stock is traded in a public market and the Shares are convertible preferred stock, the fair market value of a Share shall be the closing price of a share of the Company’s common stock reported for the business day immediately before Holder delivers its Notice of Exercise to the Company (or, in the instance where the Warrant is exercised immediately prior to the effectiveness of the Company’s initial public offering, the initial “price to public” per share price specified in the final prospectus relating to such offering), in both cases, multiplied by the number of shares of the Company’s common stock into which a Share is convertible. If the Company’s common stock is not traded in a public market, the Board of Directors of the Company shall determine fair market value in its reasonable good faith judgment.

1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant, but in any event within ten (10) days of such exercise or conversion, and, if applicable, the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not so acquired.

1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, or surrender and cancellation of this Warrant, the Company shall, at its expense, execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

1.6 Treatment of Warrant Upon Acquisition of Company.

1.6.1 “Acquisition”. For the purpose of this Warrant, “Acquisition” means any sale, license, or other disposition of all or substantially all of the assets of the Company, or any reorganization, consolidation, or merger of the Company where the holders of the Company’s securities before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction.

1.6.2 Treatment of Warrant at Acquisition.

(a) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition in which the sole consideration is cash, either (a) Holder shall exercise its conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide the Holder with written notice of its request relating to the foregoing (together with such reasonable information as the Holder may request in connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition.

(b) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that is an “arms length” sale of all or substantially all of the Company’s assets (and only its assets) to a third party that is not an Affiliate (as defined below) of the Company (a “True Asset Sale”), either (a) Holder shall exercise its conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant will continue until the Expiration Date if

the Company continues as a going concern following the closing of any such True Asset Sale. The Company shall provide the Holder with written notice of its request relating to the foregoing (together with such reasonable information as the Holder may request in connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition.

(c) Upon the closing of any Acquisition other than those particularly described in subsections (a) and (b) above, the successor entity shall assume the obligations of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and property as would be payable for the Shares issuable upon exercise of the unexercised portion of this Warrant, as if such Shares were outstanding on the record date for the Acquisition and subsequent closing. The Warrant Price and/or number of Shares shall be adjusted accordingly.

As used herein “Affiliate” shall mean any person or entity that owns or controls directly or indirectly ten (10) percent or more of the stock of Company, any person or entity that controls or is controlled by or is under common control with such persons or entities, and each of such person’s or entity’s officers, directors, joint venturers or partners, as applicable.

1.7 Conversion or Redemption of Preferred Stock. In the event that all outstanding shares of the Company’s Series A Convertible Preferred Stock are converted into shares of the Company’s Common Stock in accordance with the terms of the Company’s Certificate of Incorporation at any time prior to the Expiration Date, this Warrant shall become exercisable for Common Stock. In the event that all outstanding shares of the Company’s Series A Convertible Preferred Stock are redeemed at a price greater than the then existing Warrant Price in accordance with the terms of the Company’s Certificate of Incorporation at any time prior to the Expiration Date, this Warrant shall automatically be deemed converted pursuant to Section 1.2 above as to all Shares for which it shall not previously have been exercised or converted as of the first Mandatory Redemption Date (as that term is defined in the Company’s Certificate of Incorporation).

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the Shares payable in common stock, or other securities, then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total number and kind of securities to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend occurred. If the Company subdivides the Shares by reclassification or otherwise into a greater number of shares or takes any other action which increase the amount of stock into which the Shares are convertible, the number of shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased.

2.2 Reclassification, Exchange, Combinations or Substitution. Upon any reclassification, exchange, substitution, or other event that results in a change of the number and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall be entitled to receive, upon exercise or conversion of this Warrant,

the number and kind of securities and property that Holder would have received for the Shares if this Warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. Such an event shall include any automatic conversion of the outstanding or issuable securities of the Company of the same class or series as the Shares to common stock pursuant to the terms of the Company’s Certificate of Incorporation upon the closing of a registered public offering of the Company’s common stock. The Company or its successor shall promptly issue to Holder an amendment to this Warrant setting forth the number and kind of such new securities or other property issuable upon exercise or conversion of this Warrant as a result of such reclassification, exchange, substitution or other event that results in a change of the number and/or class of securities issuable upon exercise or conversion of this Warrant. The amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 2 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Article 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events.

2.3 Adjustments for Diluting Issuances. The Warrant Price and the number of Shares issuable upon exercise of this Warrant or, if the Shares are Preferred Stock, the number of shares of common stock issuable upon conversion of the Shares, shall be subject to adjustment, from time to time in the manner set forth in the Company’s Certificate of Incorporation as if the Shares were issued and outstanding on and as of the date of any such required adjustment. The provisions set forth for the Shares in the Company’s Certificate of Incorporation relating to the above in effect as of the Issue Date may not be amended, modified or waived, without the prior written consent of Holder unless such amendment, modification or waiver affects the rights associated with the Shares in the same manner as such amendment, modification or waiver affects the rights associated with all other shares of the same series and class as the Shares granted to the Holder.

2.4 No Impairment. The Company shall not, by amendment of its Certificate of Incorporation or through a reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this Warrant by the Company, but shall at all times in good faith assist in carrying out of all the provisions of this Article 2 and in taking all such action as may be necessary or appropriate to protect Holder’s rights under this Article against impairment.

2.5 Fractional Shares. No fractional Shares shall be issuable upon exercise or conversion of the Warrant and the number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the Warrant, the Company shall eliminate such fractional share interest by paying Holder the amount computed by multiplying the fractional interest by the fair market value of a full Share.

2.6 Certificate as to Adjustments. Upon each adjustment of the Warrant Price, the Company shall promptly notify Holder in writing, and, at the Company’s expense, promptly compute such adjustment, and furnish Holder with a certificate of its Chief Financial Officer setting forth such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish

Holder a certificate setting forth the Warrant Price in effect upon the date thereof and the series of adjustments leading to such Warrant Price.

SECOND AMENDED AND RESTATED REVOLVING PROMISSORY NOTE


$5,000,000.00		Vienna, Virginia April 25, 2005

FOR VALUE RECEIVED, the undersigned, SOURCEFIRE, INC., a Delaware corporation (“Borrower”) promises to pay to the order of SILICON VALLEY BANK, a California-chartered bank doing business in Virginia as “Silicon Valley East” (“Bank”), at such place as the holder hereof may designate, in lawful money of the United States of America, the aggregate unpaid principal amount of all advances (“Advances”) made by Bank to Borrower in accordance with the terms and conditions of the Loan and Security Agreement between Borrower and Bank dated November 29, 2002 (as amended from time to time, the “Loan Agreement”), up to a maximum principal amount of Five Million and no/100 Dollars ($5,000,000.00) (“Principal Sum”), or so much thereof as may be advanced or readvanced and remains unpaid. Borrower shall also pay interest on the aggregate unpaid principal amount of such Advances, as set forth in the Loan Agreement. All interest payable under the terms of this Note shall be calculated on the basis of a 360-day year and the actual number of days elapsed.

The unpaid Principal Sum, together with accrued interest thereon at the rate or rates set forth in the Loan Agreement, shall be payable as follows:

(a) Accrued interest only on the unpaid principal amount shall be due and payable monthly in arrears, commencing May 5, 2005, and continuing on the fifth (5^th) day of each calendar month thereafter to maturity; and

(b) Unless sooner paid, the unpaid Principal Sum, together with interest accrued and unpaid thereon, shall be due and payable in full on the Revolving Maturity Date.

bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, Borrower’s liability hereunder (and any lien, security interest or other collateral securing such liability) shall be and remain in full force and effect, as fully as if such payment had never been made, or, if prior thereto any such lien, security interest or other collateral hereafter securing Borrower’s liability hereunder shall have been released or terminated by virtue of such cancellation or surrender, this Note (and such lien, security interest or other collateral) shall be reinstated in full force and effect, and such prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect the obligations of Borrower in respect of the amount of such payment (or any lien, security interest or other collateral securing such obligation).

This Note is the “Replacement Revolving Promissory Note” described in a certain Third Amendment to Loan and Security Agreement of even date herewith between Borrower and Bank, to which reference is hereby made for a more complete statement of the terms and conditions under which the loans and advances evidenced hereby are made. This Note increases, amends and restates in its entirety that certain Amended and Restated Revolving Promissory Note dated November 3, 2003 (the “Prior Note”) in the maximum principal amount of Three Million Dollars ($3,000,000) from the Borrower in favor of the Bank.

This Note is secured as provided in the Loan Agreement. All capitalized terms used herein and not otherwise defined shall have the meanings given to such terms in the Loan Agreement.

The occurrence of any Event of Default under the Loan Agreement, shall constitute an Event of Default under the terms of this Note.

In the event this Note is not paid when due or any installment due hereunder is not paid within fifteen (15) days of the date when due, whether by maturity or acceleration, Borrower hereby appoints and designates Xxxx Xxxxxxx, Esq., Borrower’s duly constituted attorney-in-fact to confess judgment pursuant to the provisions of Section 8.01-432 of the Code of Virginia of 1950, as amended, against Borrower for all principal of and interest due and payable under this Note upon the occurrence of an Event of Default, together with attorneys’ fees and collection fees as provided herein (to the extent permitted by law), which judgment shall be confessed in the Clerk’s Office of the Circuit Court of Fairfax County, Virginia. Upon request of Bank, Borrower will execute an amendment or other agreement substituting attorneys-in-fact appointed to act for Borrower hereunder.

Borrower promises to pay all costs and expense of collection of this Note and to pay all reasonable attorneys’ fees incurred in such collection, whether or not there is a suit or action, or in any suit or action to collect this Note or in any appeal thereof. Borrower waives presentment, demand, protest, notice of protest, notice of dishonor, notice of nonpayment, and any and all other notices and demands in connection with the delivery, acceptance, performance default or enforcement of this Note, as well as any applicable statutes of limitations. No delay by Bank in exercising any power or right hereunder shall operate as a waiver of any power or right. Time is of the essence as to all obligations hereunder.
