        THIS EXPORT-IMPORT BANK LOAN AND SECURITY AGREEMENT dated January 19,
1999, between SILICON VALLEY BANK ("Bank"), whose address is 3003 Tasman Drive,
Santa Clara, California 95054 and PACKETEER, INC. ("Borrower"), whose address is
10495 N. De Anza Boulevard, Cupertino, California 95014 provides the terms on
which Bank will lend to Borrower and Borrower will repay Bank. The parties agree
as follows:

1              ACCOUNTING AND OTHER TERMS

        Accounting terms not defined in this Exim Agreement will be construed
following GAAP Calculations and determinations must be made following GAAP. The
term "financial statements" includes the notes and schedules. The terms
"including" and "includes" always mean "including (or includes) without
limitation" in this or any Loan Document. This Exim Agreement shall be construed
to impart upon Bank a duty to act reasonably at all times.

2              LOAN AND TERMS OF PAYMENT

2.1            CREDIT EXTENSIONS.

        Borrower will 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 (i) the Exim Committed Line or
(ii) the Borrowing Base, whichever is less. For purposes of this Agreement,
Borrowing Base means an amount equal to the sum of (i) ninety percent (90%) of
Exim Eligible Foreign Accounts plus (ii) fifty percent (50%) of the Exim
Eligible Foreign Inventory. Amounts borrowed under this Section may be repaid
and reborrowed during the term of this Exim Agreement.

        (b) To obtain an Advance, Borrower must notify Bank by facsimile or
telephone by 3:00 p.m. Pacific 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. Bank will credit Advances to
Borrower's deposit account. Bank may make Credit Extensions under this Exim
Agreement based on instructions from a Responsible Officer or his or her
designee or without instructions if the Credit Extensions 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 suffered by Bank from that reliance.

        (c) The Exim Committed Line terminates on the Exim Maturity Date, when
all Advances and other amounts due under this Exim Agreement are immediately
payable.

2.2            OVERADVANCES.

        If Borrower's Obligations under Section 2.1.1 exceed the lesser of
either (i) the Exim Committed Line or (ii) the Borrowing Base, Borrower must
immediately pay Bank the excess.

2.3            INTEREST RATE, PAYMENTS.

        (a) Interest Rate. Advances accrue interest on the outstanding principal
balance at a per annum rate equal to the Prime Rate. After an Event of Default,
Obligations accrue interest at 5 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.


                                       4


<PAGE>   5
        (b) Payments. Interest due on the Exim Committed Line is payable on the
19th of each month. Bank may debit any of Borrower's deposit accounts including
Account Number _____________________________ for principal and interest payments
or any amounts Borrower owes Bank. Bank will notify Borrower when it debits
Borrower's accounts. These debits are not a set-off. Payments received after
12:00 noon 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) Facility Fee. A fully earned, non-refundable Facility Fee of $3,750
due on the Closing Date; and

        (b) Bank Expenses. All Bank Expenses incurred through and after the date
of this Exim Agreement, (including reasonable attorneys' fees and expenses)
payable when due.

        (c) Exim Fee. A facility fee equal to $3,750 will be due on the Closing
Date.

        (d) Exim Bank Expenses. On the Closing Date, Exim Bank Expenses incurred
through the date hereof.

2.5            USE OF PROCEEDS.

        Borrower will use the proceeds of the Credit Extensions only for the
purposes specified in the Borrower Agreement. Borrower will not use the proceeds
of the Credit Extensions for any purpose prohibited by the Borrower Agreement.

3              CONDITIONS OF LOANS

3.1            CONDITIONS PRECEDENT TO INITIAL CREDIT EXTENSION.

        Bank's obligation to make the initial Credit Extension is subject to the

4              CREATION OF SECURITY INTEREST

4.1            GRANT OF SECURITY INTEREST.

        Borrower grants Bank a continuing security interest in all presently
existing and later acquired Collateral to secure all Obligations and performance
of each of Borrower's duties under the Loan Documents. Except for Permitted
Liens, and investment property or deposit accounts of Borrower held in accounts
maintained by securities intermediaries or depository institutions, as
applicable, any security interest will be a first priority security interest in
the Collateral. Bank may place a "hold" on any deposit account pledged as
Collateral.

5              REPRESENTATIONS AND WARRANTIES

        Borrower represents and warrants 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 be so
qualified could not, with reasonable likelihood, cause a Material Adverse
Change.

        The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's formation documents, nor
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, with reasonable likelihood, cause a Material
Adverse Change.

5.2            COLLATERAL.

        Borrower has good title to the Collateral, free of Liens except
Permitted Liens. The Exim Eligible Foreign 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. Borrower has no notice of any actual or
imminent Insolvency Proceeding of any account debtor whose accounts are an Exim
Eligible Foreign Account in any Borrowing Base Certificate. All Exim Eligible
Foreign 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. 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.

5.3            LITIGATION.

        Except as shown in the Schedule, there are no actions or proceedings
pending or, to Borrower's knowledge, threatened by or against Borrower or any
Subsidiary in which an adverse decision could, with reasonable likelihood, cause
a Material Adverse Change.

5.4            NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS.

        All consolidated financial statements for Borrower, and any Subsidiary,
delivered to Bank 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 Bank.


                                       6


<PAGE>   7
5.5            SOLVENCY.

        The fair salable value of Borrower's assets (including goodwill minus
disposition costs) exceeds the fair value of its liabilities; the Borrower is
not left with unreasonably small capital after the transactions in this Exim
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. Borrower is not engaged
as one of its important activities in extending credit for margin stock (under
Regulations T and U of the Federal Reserve Board of Governors) . Borrower has
complied with the Federal Fair Labor Standards Act. Borrower has not violated
any laws, ordinances or rules, the violation of which could, with reasonable
likelihood, cause a Material Adverse Change. 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 taxes. 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.

5.7            SUBSIDIARIES.

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

5.8            FULL DISCLOSURE.

        No representation, warranty or other statement of Borrower in any
certificate or written statement given to Bank contains any untrue statement of
a material fact or omits to state a material fact necessary to make the
statements contained in the certificates or statements not misleading.

6              AFFIRMATIVE COVENANTS

        Borrower will do all of the following:

6.1            GOVERNMENT COMPLIANCE.

        Borrower will maintain its and all Subsidiaries' corporate existence and
good standing in its jurisdiction of incorporation and maintain qualification in
each jurisdiction in which the failure to so qualify could, with reasonable
likelihood, have a material adverse effect on Borrower's business or operations.
Borrower will comply, and have each Subsidiary comply, with all laws, ordinances
and regulations to which it is subject, noncompliance with which could, with
reasonable likelihood, have a material adverse effect on Borrower's business or
operations or cause a Material Adverse Change.

        (a) Borrower will deliver to Bank: (i) as soon as available, but no

costs to Borrower or any Subsidiary of $100,000 or more; (iv) budgets, sales
projections, operating plans or other financial information Bank requests; and
(v) prompt notice of any material change in the composition of the Intellectual
Property, including any subsequent ownership right of Borrower in or to any
Copyright, Patent or Trademark not shown in any intellectual property security
agreement between Borrower and Bank or knowledge of an event that materially
adversely affects the value of the Intellectual Property.

        (b) Within 30 days after the last day of each month, Borrower will
deliver to Bank with the monthly financial statements a Compliance Certificate
signed by a Responsible Officer in the form of Exhibit D.

        (c) Within 20 days after the last day of each month, Borrower will
deliver to Bank a Borrowing Base Certificate and a copy of the Export Order(s)
against which the Borrower is requesting a disbursement, together with aged
listings of accounts receivable and accounts payable and an eligible foreign
inventory report. Borrower shall also deliver promptly to Bank copies of any
Export Orders requested by Bank. Additionally, the Borrower shall deliver to the
Bank at least once every thirty (30) calendar days a Borrowing Base Certificate
current within the past five (5) Business Days, which requirement may be
satisfied by submission of a Borrowing Base Certificate when requesting a
disbursement.

        (d) Bank has the right to audit Borrower's Collateral at Borrower's
expense, but the audits will be conducted no more often than every 6 months
unless an Event of Default has occurred and is continuing. The initial audit of
Borrower's Collateral shall be completed no later than 90 days from the Closing
Date.

6.3            INVENTORY; RETURNS.

        Borrower will keep all Inventory in good and marketable condition
(except for ordinary wear and tear), free from material defects. Returns and
allowances between Borrower and its account debtors will follow Borrower's
customary practices as they exist at execution of this Exim Agreement. Borrower
must promptly notify Bank of all returns, recoveries, disputes and claims, that
involve more than $100,000.

6.4            TAXES.

        Borrower will make, and cause each Subsidiary to make, timely payment of
all material federal, state, and local taxes or assessments and will deliver to
Bank, on demand, appropriate certificates attesting to the payment.

6.5            INSURANCE.

        Borrower will keep its business and the Collateral insured for risks and
in amounts, as Bank requests. Insurance policies will be in a form, with
companies, and in amounts that are satisfactory to Bank. All property policies
will have a lender's loss payable endorsement showing Bank as an additional loss
payee and all liability policies will show the Bank as an additional insured and
provide that the insurer must give Bank at least 20 days notice before canceling
its policy. At Bank's request, Borrower will deliver certified copies of
policies and evidence of all premium payments. Proceeds payable under any policy
will, at Bank's option, be payable to Bank on account of the Obligations.

6.6            EXIM INSURANCE.

        If required by Bank, Borrower will obtain, and pay when due all premiums
with respect to, and maintain uninterrupted foreign credit insurance. In
addition, Borrower will execute in favor of Bank an assignment of proceeds of
any insurance policy obtained by Borrower and issued by Exim Bank insuring
against comprehensive commercial and political risk (the "EXIM Bank Policy").
The insurance proceeds from 


                                       8


<PAGE>   9
the EXIM Bank Policy assigned or paid to Bank will be applied to the balance
outstanding under this Exim Agreement. Borrower will immediately notify Bank and
Exim Bank in writing upon submission of any claim under the Exim Bank Policy.
Then Bank will not be obligated to make any further Credit Extensions to
Borrower without prior approval from Exim Bank.

6.7            BORROWER AGREEMENT.

        Borrower will comply with all terms of the Borrower Agreement. If any
provision of the Borrower Agreement conflicts with any provision contained in
this Exim Agreement, the more strict provision, with respect to the Borrower,
will control.

6.8            PRIMARY ACCOUNTS.

        Borrower will maintain its primary operating accounts with Bank.

6.9            TERMS OF SALE.

Patent and Trademark Office or the United States Copyright Office Intellectual
Property rights on Exhibits A, B, C, and D to the Intellectual Property Security

Intellectual Property rights developed or acquired including revisions or
additions with any product before the sale or licensing of the product to any
third party.

enforceability of the Intellectual Property and promptly advise Bank in writing

9              BANK'S RIGHTS AND REMEDIES

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 Exim 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 is commercially reasonable;

        (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


                                       12


<PAGE>   13
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
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 Credit Extensions
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, as required under the terms of this Agreement or any
related documents, 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.

9.5            BANK'S LIABILITY FOR COLLATERAL.

        If Bank complies with reasonable banking practices 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 Exim 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.

9.8            EXIM NOTIFICATION.

        Bank has the right to immediately notify Exim Bank in writing if it has
knowledge of any of the following events: (1) any failure to pay any amount due
under this Exim Agreement; (2) the Borrowing Base is less than the sum of the
outstanding Credit Extensions; (3) any failure to pay when due any amount
payable to Bank under any Loan owing by Borrower to Bank; (4) the filing of an
action for debtor's relief by, against or on behalf of Borrower; (5) any
threatened or pending material litigation against Borrower, or any dispute
involving Borrower.

        If Bank sends a notice to Exim Bank, Bank has the right to send Exim
Bank a written report on the status of events covered by the notice every 30
days after the date of the original notification, until Bank files a claim with
Exim Bank or the defaults have been cured (but no Credit Extensions may be
requested during the cure period unless Exim Bank gives its written approval).
If directed by Exim Bank, Bank will have the right to exercise any rights it may
have against the Borrower to demand the immediate repayment of all amount
outstandings under the Exim Loan Documents.

10             NOTICES

        Unless otherwise provided in this Agreement, notices or demands by any
party about this Exim Agreement or any other related agreement must be in
writing and be personally delivered or sent by an overnight delivery service, by
certified mail, postage prepaid, return receipt requested, or by telefacsimile
to the addresses first written above. A Party may change its notice address by
giving the other Party written notice.

11             CHOICE OF LAW , VENUE AND JURY TRIAL WAIVER

        California law governs the Loan Documents without regard to principles
of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction
of the State and Federal courts in Santa Clara County, California. Any
references in the Borrower Agreement to the laws of the State of New York, shall
be deemed a reference to the laws of the State of California.

BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE
OF ACTION ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY CONTEMPLATED
TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS
WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS EXIM
AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.
