         THIS LOAN AND SECURITY AGREEMENT (this "Agreement") dated April 26,
         2001, between SILICON VALLEY BANK ("Bank"), whose address is 3003
         Tasman Drive, Santa Clara, California 95054 with a loan production
         office located at 4455 E. Camelback Road, Suite E-290, Phoenix, Arizona
         85018 and TASER INTERNATIONAL, INC. ("Borrower"), whose address is 7860
         East McClain Drive, Suite 2, Scottsdale, AZ 85260 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 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.

2        LOAN AND TERMS OF PAYMENT

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 Committed Revolving Line.
Amounts borrowed under this Section may be repaid and reborrowed during the term
of this Agreement.

         (b) To obtain an Advance, Borrower must notify Bank by facsimile or
telephone by 12:00 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 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 terminates on the Revolving Maturity
Date, when all Advances are immediately payable.

         (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.

2.2      INTEREST RATE, PAYMENTS.

         (a) Interest Rate. Advances accrue interest on the outstanding
principal balance at a per annum rate of 1 percentage point above 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.

         (b) Payments. Interest due on the Committed Revolving Line is payable
on the last 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


                                       4
<PAGE>   5
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 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.

2.3      FEES.

         Borrower will pay:

         (a) Facility Fee. A fully earned, non-refundable Facility Fee of
$45,000 due no later than May 15, 2001; and

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

3        CONDITIONS OF LOANS

3.1      CONDITIONS PRECEDENT TO INITIAL ADVANCE.

         Bank's obligation to make the initial Advance is subject to the
condition precedent that it receive the agreements, documents and fees it
requires.

3.2      CONDITIONS PRECEDENT TO ALL ADVANCES.

         Bank's obligations to make each Advance, including the initial Advance,
is subject to the following:

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


         (b) the representations and warranties in Section 5 must be materially
true on the date of the Payment/Advance Form and on the effective date of each
Advance and no Event of Default may have occurred and be continuing, or result
from the Advance. Each Advance is Borrower's representation and warranty on that
date that the representations and warranties of Section 5 remain true.


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, 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. If this Agreement is terminated, Bank's lien and security interest
in the Collateral will continue until Borrower fully satisfies its Obligations.

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


                                       5
<PAGE>   6
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
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 reasonably be expected to cause a Material
Adverse Change.

5.2      COLLATERAL.

         Borrower has good title to the Collateral, free of Liens except
Permitted Liens. All Inventory is in all material respects of good and
marketable quality, free from material defects.

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.

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.

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
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 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 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 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 do so could not reasonably be
expected to cause a Material Adverse Change.

<PAGE>   7
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 Bank (taken together with all such
written certificates and written statements 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. Bank
recognizes that the projections and forecasts provided by Borrower in good faith
and based upon reasonable assumptions are not viewed as facts and that actual
results during the period or periods covered by such projections and forecasts
may differ from the projected and forecasted results.

6        AFFIRMATIVE COVENANTS

         Borrower will do all of the following for so long as Bank has an
obligation to lend, or there are outstanding Obligations:

6.1      GOVERNMENT COMPLIANCE.

         Borrower will maintain its and all Subsidiaries' legal existence and
good standing in its jurisdiction of formation and maintain qualification in
each jurisdiction in which the failure to so qualify would reasonably be
expected to cause 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 have a material adverse effect on Borrower's business or operations
or would reasonably be expected to cause a Material Adverse Change.

6.2      FINANCIAL STATEMENTS, REPORTS, CERTIFICATES.

         (a) Borrower will deliver to Bank: (i) as soon as available, but no
later than 30 days after the last day of each month, a company prepared
consolidated balance sheet and income statement covering Borrower's consolidated
operations during the period certified by a Responsible Officer and in a form
acceptable to Bank; (ii) as soon as available, but no later than 90 days after
the last day of Borrower's fiscal year, audited consolidated financial
statements prepared under GAAP, consistently applied, together with an
unqualified opinion on the financial statements from an independent certified
public accounting firm reasonably acceptable to Bank; (iii) a prompt report of
any legal actions pending or threatened against Borrower or any Subsidiary that
could result in damages or costs to Borrower or any Subsidiary of $100,000 or
more; and (iv) budgets, sales projections, operating plans or other financial
information Bank reasonably requests.

         (b) Allow Bank to audit Borrower's Collateral at Borrower's expense.
Such audits will be conducted no more often than every year unless an Event of
Default has occurred and is continuing.

6.3      INVENTORY; RETURNS.

         Borrower will keep all Inventory in good and marketable condition, 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 Agreement. Borrower must promptly notify Bank of all returns, recoveries,
disputes and claims, that involve more than $50,000.



                                       7
<PAGE>   8
6.4      TAXES.

         Borrower will make, and cause each Subsidiary to make, timely payment
of all material federal, state, and local taxes or assessments (other than taxes
and assessments which Borrower is contesting in good faith, with adequate
reserves maintained in accordance with GAAP) 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 standard for Borrower's industry, and as Bank may reasonably
request. Insurance policies will be in a form, with companies, and in amounts
that are satisfactory to Bank in Bank's reasonable discretion. 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      PRIMARY ACCOUNTS.

         Borrower will maintain its primary depository and operating accounts
with Bank.

6.7      FURTHER ASSURANCES.

         Borrower will execute any further instruments and take further action
as Bank reasonably requests to perfect or continue Bank's security interest in
the Collateral or to effect the purposes of this Agreement.

7        NEGATIVE COVENANTS

         Borrower will not do any of the following without Bank's prior written
consent, which will not be unreasonably withheld, for so long as Bank has an
obligation to lend or there are any outstanding Obligations:

         Convey, sell, lease, transfer or otherwise dispose of (collectively
"Transfer"), or permit any of its Subsidiaries to Transfer, all or any part of
its business or property, except for Transfers (i) of Inventory in the ordinary
course of business; (ii) of non-exclusive licenses and similar arrangements for
the use of the property of Borrower or its Subsidiaries in the ordinary course

         Engage in or permit any of its Subsidiaries to engage in any business
other than the businesses currently engaged in by Borrower or reasonably related

25% (other than by the sale of Borrower's equity securities in a public offering
or to venture capital investors so long as Borrower identifies the venture
capital investors prior to the closing of the investment). Borrower will not,
without at least 30 days prior written notice, relocate its chief executive
office or add any new offices or business locations in which Borrower maintains
or stores over $5,000 in Borrower's assets or property.

<PAGE>   9
7.3      MERGERS OR ACQUISITIONS.

         Merge or consolidate, or permit any of its Subsidiaries to merge or
consolidate, with any other Person, or acquire, or permit any of its
Subsidiaries to acquire, all or substantially all of the capital stock or
property of another Person, except where (i) no Event of Default has occurred
and is continuing or would result from such action during the term of this
Agreement and (ii) such transaction would not result in a decrease of more than
25% of Tangible Net Worth. A Subsidiary may merge or consolidate into another
Subsidiary or into Borrower.

7.4      INDEBTEDNESS.

         Create, incur, assume, or be liable for any Indebtedness, or permit any
Subsidiary to do so, other than Permitted Indebtedness.

7.5      ENCUMBRANCE.

         Create, incur, or allow any Lien on any of its property, or assign or
convey any right to receive income, including the sale of any Accounts, or

any Collateral not to be subject to the first priority security interest granted
here, subject to Permitted Liens.

         Directly or indirectly enter into or permit to exist any material
transaction with any Affiliate of Borrower except for transactions that are in
the ordinary course of Borrower's business, upon fair and reasonable terms that
are no less favorable to Borrower than would be obtained in an arm's length
transaction with a nonaffiliated Person.

7.8      SUBORDINATED DEBT.

         Make or permit any payment on any Subordinated Debt, except under the
terms of the Subordinated Debt, or amend any provision in any document relating

7.9      COMPLIANCE.

minimum funding requirements of ERISA, permit a Reportable Event or Prohibited

<PAGE>   10
8.1      PAYMENT DEFAULT.

         If Borrower fails to pay any of the Obligations within 3 days after
their due date. During the additional period the failure to cure the default is

8.2      COVENANT DEFAULT.


         If Borrower violates any covenant in Section 7 or does not perform or
observe any other material term, condition or covenant in this Agreement, any
Loan Documents, or in any agreement between Borrower and Bank and as to any
default under a term, condition or covenant that can be cured, has not cured the
default within 10 days after it occurs, or if the default cannot be cured within
10 days or cannot be cured after Borrower's attempts within 10 day period, and
the default may be cured within a reasonable time, then Borrower has an
additional period (of not more than 30 days) to attempt to cure the default.
During the additional time, the failure to cure the default is not an Event of
Default (but no Advances will be made during the cure period);


8.3      MATERIAL ADVERSE CHANGE.

Bank's security interests in the Collateral.

8.4      ATTACHMENT.

         If any material portion of Borrower's assets is attached, seized,
levied on, or comes into possession of a trustee or receiver and the attachment,
seizure or levy is not removed in 10 days, or if Borrower is enjoined,
restrained, or prevented by court order from conducting a material part of its
business or if a judgment or other claim becomes a Lien on a material portion of
Borrower's assets, or if a notice of lien, levy, or assessment is filed against
any of Borrower's assets by any government agency and not paid within 10 days
after Borrower receives notice. These are not Events of Default if stayed or if
a bond is posted pending contest by Borrower (but no Advances will be made
during the cure period);

8.5      INSOLVENCY.

         If Borrower becomes insolvent or if Borrower begins an Insolvency

Insolvency Proceeding is dismissed);

8.6      OTHER AGREEMENTS.

         If there is a default in any agreement between Borrower and a third
party that gives the third party the right to accelerate any Indebtedness
exceeding $100,000 or that could cause a Material Adverse Change;

8.7      JUDGMENTS.

         If a money judgment(s) in the aggregate of at least $50,000 is rendered

representation in this Agreement or in any writing delivered to Bank or to
induce Bank to enter this Agreement or any Loan Document; or

8.9      GUARANTY.


         Any guaranty of any Obligations ceases for any reason to be in full
force or any Guarantor does not perform any obligation under any guaranty of the
Obligations, or any material misrepresentation or material misstatement exists
now or later in any warranty or representation in any guaranty of the
Obligations or in any certificate delivered to Bank in connection with the

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 0 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
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; 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


                                       11
<PAGE>   12
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 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

         All notices or demands by any party about this 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 set forth at the beginning of
this Agreement. A party may change its notice address by giving the other party
