LOAN AND SECURITY AGREEMENT

is 3003 Tasman Drive, Santa Clara, California 95054 and having a loan production office at 3343 Peachtree Road, NE, Suite 312, Atlanta, Georgia 30326 and WITNESS SYSTEMS, INC., a corporation
organized and in good standing in the State of Delaware ("Borrower"), whose address is 300 Colonial Center Parkway, Roswell, Georgia, 30076 provides the terms on which Bank will lend to Borrower and
Borrower will repay Bank. The parties agree as follows:

1ACCOUNTING AND OTHER TERMS

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 attached thereto. The terms "including" and "includes" always mean "including (or includes) without limitation," in this or any Loan Document.

2LOAN AND TERMS OF PAYMENT

2.1Promise 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.



(a)  Bank
will make Advances not exceeding (i) the lesser of (A) the Committed Revolving Line or (B) the Borrowing Base, minus (ii) the amount of
all outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit) and minus the Cash Management Sublimit. 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 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. For purposes of this Section 2.1.1(b), 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.

(c)  The
Committed Revolving Line terminates on the Revolving Maturity Date, when all Advances are immediately payable.

(d)  Bank's
obligation to lend the undisbursed portion of the Committed Revolving Line 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.



Borrower
may use up to Two Hundred Thousand Dollars ($200,000) for Bank's Cash Management Services, which may include merchant services, direct deposit of payroll, business credit card,
and check cashing services identified in various cash management services agreements related to such services (the "Cash Management Services"). Such aggregate amounts utilized under the Cash
Management Services Sublimit 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 any Cash Management Services will be treated as Advances under the Committed Revolving Line and will accrue interest at the rate for Advances.



Bank
will issue or have issued Letters of Credit for Borrower's account not exceeding (i) the lesser of the Committed Revolving Line or the Borrowing Base, minus (ii) the
outstanding principal balance of the Advances and the Cash Management Sublimit; however, the face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit) may not
at any time exceed Five Million Dollars ($5,000,000). Each Letter of Credit will have an expiry date of no later than one hundred eighty (180) days after the Revolving Maturity Date, but
Borrower's obligations to reimburse Bank under the Letters of Credit will be secured by cash on terms acceptable to Bank at any time after the occurrence of any Event of Default or after the Revolving
Maturity Date if the term of this Agreement is not extended by Bank. Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request. Prior
to or simultaneously with the opening of each
Letter of Credit, Borrower shall pay to Bank, a letter of credit fee (each a "Letter of Credit Fee" and collectively the "Letter of Credit Fees") in an amount equal to three quarters of one percent
(.75%) per annum of the face amount of the Letter of Credit. Such Letter of Credit Fees shall be paid in advance upon the issuance of the Letter of Credit and upon each anniversary thereof, if any. In
addition, Borrower shall pay to Bank any and all additional issuance, negotiation, processing, transfer or other fees to the extent and as and when required by Bank.

2.2Overadvances.

If
Borrower's Obligations under Sections 2.1.1 and 2.1.2 exceed the lesser of either (i) the Committed Revolving Line or (ii) the Borrowing Base, Borrower shall upon notice
from Bank, immediately pay such excess or secure such excess with a pledge of cash maintained at Bank.

2.3Interest Rate, Payments.

(a)Interest Rate.Advances accrue interest on the outstanding principal balance in accordance with the
Revolving Promissory Note. After an Event of Default, Obligations accrue interest at five percent (5%) 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 Committed Revolving Line is payable on the fifteenth (15th) day
of each month. Bank may debit any of Borrower's deposit accounts including Account Number                        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 12:00 noon Eastern 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.

2.4Fees.

Borrower
will pay:

(a)Facility Fee.A fully earned, nonrefundable fee in the amount of Fifteen Thousand Dollars ($15,000), half of
which shall be due and payable on the Closing Date and the balance of which ($7,500) shall be due and payable at the time of issuance of the next Letter of Credit requested after the Closing Date, or
the first Advance requested under this Agreement.

(b)Bank Expenses.All Bank Expenses (including reasonable attorneys' fees in connection with negotiation and

9BANK'S RIGHTS AND REMEDIES

9.1Rights 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, 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 Bank or its Affiliate 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. If an Event of Default occurs and while it
continues, Bank is granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower's labels, Patents, Copyrights, rights of use of any name, trade
secrets, trade names, Trademarks, service marks, and advertising matter, or any 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.

9.2Power 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 Credit Extensions terminates.

9.3Accounts 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.

9.4Bank 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 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.

9.5Bank'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. Except as otherwise provided in this
Section 9.5, Borrower bears all risk of loss, damage or destruction of the Collateral.

---

9.6Remedies 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.

9.7Demand 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.
