     by the Borrower to give such instructions. This paragraph will survive this
     Agreement's termination, and will benefit the Bank and its officers,
     employees, and agents.

5.2  Direct Debit (Pre-Billing). The Borrower agrees that the Bank will debit
the Borrower's deposit account number 14871-03852, or such other of the
Borrower's accounts with the Bank as designated in writing by the Borrower (the
"Designated Account") on the date each payment of principal and interest and any
fees from the Borrower becomes due (the "Due Date"). Approximately 10 days prior
to each Due Date, the Bank will mail to the Borrower a statement of the amounts
that are expected to be due on that Due Date, based on current information (the
"Billed Amount"). The Bank will debit the Designated Account for the Billed
Amount, regardless of the actual amount due on that date (the "Accrued Amount").
If the Billed Amount debited to the Designated Account differs from the Accrued
Amount, the discrepancy will be added or subtracted from the amount due on the
next due date. Regardless of any such discrepancy, interest will continue to
accrue based on the actual amount of principal outstanding without compounding.
The Bank will not pay the Borrower interest on any overpayment. If there are
insufficient funds in the Designated Account on the date the Bank enters any
debit authorized by this Agreement, the debit will be reversed.

5.3  Banking Days. Unless otherwise provided in this Agreement, a banking-day is
a day other than a Saturday or a Sunday on which the Bank is open for business
in California. All payments and disbursements which would be due on a day which
is not a banking day will be due on the next banking day. All payments received
on a day which is not a banking day will be applied to the credit on the next
banking day.

5.4  Additional Costs. The Borrower will pay the Bank, on demand, for the Bank's
costs or losses arising from any statute or regulation, or any request or
requirement of a regulatory agency which is applicable to all national banks or
a class of all national banks. The costs and losses will be allocated to the
loan in a manner determined by the Bank, using any reasonable method. The costs
include the following:

(a)  any reserve or deposit requirements; and

(b)  any capital requirements relating to the Bank's assets and commitments for
     credit.

5.5  Interest Calculation. Except as otherwise stated in this Agreement, all
interest and fees, if any, will be computed on the basis of a 360-day year and
the actual number of days elapsed. This results in more interest or a higher fee
than if a 365-day year is used. Installments of principal which are not paid
when due under this Agreement shall continue to bear interest until paid.

5.6  Default Rate. Upon the occurrence of any default under this Agreement,
principal amounts outstanding under this Agreement will at the option of the
Bank bear interest at a rate which is 2 percentage point(s) higher than the rate
of interest otherwise provided under this Agreement. This will not constitute a
waiver of any default.

5.7  Interest Compounding. At the Bank's sole option in each instance, any
interest, fees or costs which are not paid when due under this Agreement shall
bear interest from the due date at the Bank's Prime Rate plus 2 percentage
points. This may result in compounding of interest.

6.  CONDITIONS

The Bank must receive any documents and other items it may reasonably require,
including but not limited to the following items, in form and content acceptable
to the Bank, before it is required to extend any credit to the Borrower under
this Agreement.

Three Million Dollars ($3,000,000).

[LOGO] Bank of America
================================================================================
To:                                                          Continuing Guaranty

                                        Borrowers:  Sunrise Telecom, Inc.
     Bank of America, N.A.
                                        Guarantors: Hukk Engineering, Inc.

     (1) For valuable consideration, the undersigned ("Guarantors") jointly and
severally unconditionally guarantee and promise to pay to Bank of America, N.A.
("Bank"), or order, on demand, in lawful money of the United States, any and all
indebtedness of Sunrise Telecom, Inc. ("Borrowers") to Bank. The word
"indebtedness" is used herein in its most comprehensive sense and includes any
and all advances, debts, obligations, and liabilities of Borrowers or any one or
more of them to Bank, heretofore, now, or hereafter made, incurred or created,
whether voluntary or involuntary and however arising, whether direct or acquired
by Bank by assignment or succession, whether due or not due, absolute or
contingent, liquidated or unliquidated, determined or undetermined, and whether
Borrowers may be liable individually or jointly with others, or whether recovery
upon such indebtedness may be or hereafter become barred by any statute of
limitations, or whether such indebtedness may be or hereafter become otherwise
unenforceable.

     (2) The liability of Guarantors under this Guaranty (exclusive of liability
under any other guaranties executed by Guarantors) shall not exceed at any one
time the total of (a) Three Million and 00/100 Dollars ($3,000,000.00), for the
principal amount of the indebtedness and (b) all interest, fees, and other costs
and expenses relating to or arising out of the indebtedness or such part of the
indebtedness as shall not exceed the foregoing limitation. It is provided,
however, that the amount guaranteed under this Guaranty shall not exceed the
Maximum Guaranteed Amount. "Maximum Guaranteed Amount" means the greater of: (x)
the "reasonably equivalent value" received by Guarantors in exchange for or in
connection with Guarantors' execution of this Guaranty; or (y) ninety percent
(90%) of the excess of (i) a "fair valuation" of the amount of the assets of
Guarantors as of the applicable date of determination of the incurrence of
Guarantors' obligations under this Guaranty over (ii) a "fair valuation" of
Guarantors' debts as of such date. For purposes of the definition of "Maximum
Guaranteed Amount", "reasonably equivalent value", "fair valuation" and the
calculation of assets and other property and debts shall be determined in
accordance with applicable federal and California state laws governing the
determination of the insolvency of a debtor and to further the intent of the
parties not to render Guarantors insolvent or to leave Guarantors with an
unreasonably small amount of capital in relation to their business, in all cases
at the applicable date for determination of the incurrence of Guarantors'
obligations under this Guaranty. Bank may permit the indebtedness to exceed
Guarantors' liability, and may apply any amounts received from any source, other
than from Guarantors, to the unguaranteed portion of the indebtedness. This is a
continuing guaranty relating to any indebtedness, including that arising under
successive transactions which shall either continue the indebtedness or from
time to time renew it after it has been satisfied. Any payment by Guarantors
shall not reduce their maximum obligation hereunder, unless written notice to
that effect be actually received by Bank at or prior to the time of such
payment.

     (3) If any Borrower is a partnership and any Guarantor is a general partner
of that partnership, then such Guarantor shall not be liable under this Guaranty
for any indebtedness of such Borrower which is secured by real property;
provided, however, that such Guarantor shall remain liable under partnership law
for all the indebtedness of such Borrower.

     (4) The obligations hereunder are joint and several, and independent of the
obligations of Borrowers, and a separate action or actions may be brought and
prosecuted against Guarantors whether action is brought against Borrowers or
whether Borrowers be joined in any such action or actions; and Guarantors waive
the benefit of any statute of limitations affecting their liability hereunder.

     (5) Guarantors authorize Bank, without notice or demand and without
affecting their liability hereunder, from time to time, either before or after
revocation hereof, to (a) renew, compromise, extend, accelerate, or otherwise
change the time for payment of, or otherwise change the terms of the
indebtedness or any part thereof, including increase or decrease of the rate of
interest thereon; (b) receive and hold security for the payment of this Guaranty
or any of the indebtedness, and exchange, enforce, waive, release, fail to
perfect, sell, or otherwise dispose of any such security; (c) apply such
security and direct the order or manner of sale thereof as Bank in its
discretion may determine; and (d) release or substitute any one or more of the
endorsers or guarantors.

     (6) Guarantors waive any right to require Bank to (a) proceed against
Borrowers; (b) proceed against or exhaust any security held from Borrowers; or
(c) pursue any other remedy in Bank's power whatsoever. Guarantors waive any
defense arising by reason of any disability or other defense of Borrowers, or
the cessation from any cause whatsoever of the liability of Borrowers, or any
claim that Guarantors' obligations exceed or are more burdensome than those of
Borrowers. Until the indebtedness shall have been paid in full, even though the
indebtedness is in excess of Guarantors' liability hereunder, Guarantors waive
any right of subrogation, reimbursement, indemnification, and contribution
(contractual, statutory, or otherwise) including, without limitation, any claim
or right of subrogation under the Bankruptcy Code (Title 11, United States Code)
or any successor statute, arising from the existence or performance of this
Guaranty and Guarantors waive any right to enforce any remedy which Bank now has
or may hereafter have against Borrowers and waive any benefit of, and any right
to participate in, any security now or hereafter held by Bank. Guarantors waive
all presentments, demands for performance, notices of nonperformance, protests,
notices of protest, notices of dishonor, and notices of acceptance of this
Guaranty and of the existence, creation, or incurring of new or additional
Indebtedness.

<PAGE>

     (7)  (a)  Guarantors understand and acknowledge that if Bank forecloses,
either by judicial foreclosure or by exercise of power of sale, any deed of
trust securing the indebtedness, that foreclosure could impair or destroy any
ability that Guarantors may have to seek reimbursement, contribution, or
indemnification from Borrowers or others based on any right Guarantors may have
of subrogation, reimbursement, contribution, or indemnification for any amounts
paid by Guarantors under this Guaranty. Guarantors further understand and
acknowledge that in the absence of this paragraph, such potential impairment or
destruction of Guarantors' rights, if any, may entitle Guarantors to assert a
defense to this Guaranty based on Section 580d of the California Code of Civil
Procedure as interpreted in Union Bank v. Gradsky, 265 Cal. App. 2d. 40 (1968).
                            ---------------------
By executing this Guaranty, Guarantors freely, irrevocably, and unconditionally:
(i) waive and relinquish that defense and agree that Guarantors will be fully
liable under this Guaranty even though Bank may foreclose, either by judicial
foreclosure or by exercise of power of sale, any deed of trust securing the
indebtedness; (ii) agree that Guarantors will not assert that defense in any
action or proceeding which Bank may commence to enforce this Guaranty; (iii)
acknowledge and agree that the rights and defenses waived by Guarantors in this
Guaranty include any right or defense that Guarantors may have or be entitled to
assert based upon or arising out of any one or more of Sections 580a, 580b,
580d, or 726 of the California Code of Civil Procedure or Section 2848 of the
California Civil Code; and (iv) acknowledge and agree that Bank is relying on
this Waiver in creating the indebtedness, and that this waiver is a material
part of the consideration which Bank is receiving for creating the indebtedness.

          (b) Guarantors waive any rights and defenses that are or may become
available to Guarantors by reason of Sections 2787 to 2855, inclusive, of the
California Civil Code.

          (c) Guarantors waive all rights and defenses that Guarantors may have
because any of the indebtedness is secured by real property. This means, among
other things: (I) Bank may collect from Guarantors without first foreclosing on
any real or personal property collateral pledged by Borrowers; and (ii) if Bank
forecloses on any real property collateral pledged by Borrowers: (1) the amount
of the indebtedness may be reduced only by the price for which that collateral
is sold at the foreclosure sale, even if the collateral is worth more than the
sale price, and (2) Bank may collect from Guarantors even if Bank, by
foreclosing on the real property collateral, has destroyed any right Guarantors
may have to collect from Borrowers. This is an unconditional and irrevocable
waiver of any rights and defenses Guarantors may have because any of the
indebtedness is secured by real property. These rights and defenses include, but
are not limited to, any rights or defenses based upon Section 580a, 580b, 580d,
or 726 of the California Code of Civil Procedure.

          (d) Guarantors waive any right or defense they may have at law or
equity, including California Code of Civil Procedure Section 580a, to a fair
market value hearing or action to determine a deficiency judgment after a
foreclosure.

          (e) No provision or waiver in this Guaranty shall be construed as
limiting the generality of any other waiver contained in this Guaranty.

     (8) Guarantors acknowledge and agree that they shall have the sole
responsibility for obtaining from Borrowers such information concerning
Borrowers' financial conditions or business operations as Guarantors may
require, and that Bank has no duty at any time to disclose to Guarantors any
information relating to the business operations or financial conditions of
Borrowers.

     (9) To secure all of Guarantors' obligations hereunder, Guarantors assign
and grant to Bank a security interest in all moneys, securities, and other
property of Guarantors now or hereafter in the possession of Bank, all deposit
accounts of Guarantors maintained with Bank, and all proceeds thereof. Upon
default or breach of any of Guarantors' obligations to Bank, Bank may apply any
deposit account to reduce the indebtedness and may foreclose any collateral as
provided in the Uniform Commercial Code and in any security agreements between
Bank and Guarantors.

     (10) Any obligations of Borrowers to Guarantors, now or hereafter existing,
including but not limited to any obligations to Guarantors as subrogees of Bank
or resulting from Guarantors' performance under this Guaranty, are hereby
subordinated to the indebtedness. Such obligations of Borrowers to Guarantors if
Bank so requests shall be enforced and performance received by Guarantors as
trustees for Bank, and the proceeds thereof shall be paid over to Bank on
account of the indebtedness, but without reducing or affecting in any manner the
liability of Guarantors under the provisions of this Guaranty.

     (11) This Guaranty may be revoked at any time by Guarantors in respect to
future transactions, unless there is a continuing consideration as to such
transactions which Guarantors do not renounce. Such revocation shall be
effective upon actual receipt by Bank, at the address shown below or at such
other address as may have been provided to Guarantors by Bank, of written notice
of revocation. Revocation shall not affect any of Guarantors' obligations or
Bank's rights with respect to transactions which precede Bank's receipt of such
notice, regardless of whether or not the indebtedness related to such
transactions, before or after revocation, has been renewed, compromised,
extended, accelerated, or otherwise changed as to any of its terms, including
time for payment or increase or decrease of the rate of interest thereon, and
regardless of any other act or omission of Bank authorized hereunder. Revocation
by any one or more of Guarantors shall not affect any obligations of any
nonrevoking Guarantors. If this Guaranty is revoked, returned, or canceled, and
subsequently any payment or transfer of any interest in property by Borrowers to
Bank is rescinded or

<PAGE>

must be returned by Bank to Borrowers, this Guaranty shall be reinstated with
respect to any such payment or transfer, regardless of any such prior
revocation, return, or cancellation.

     (12) Where any one or more of Borrowers are corporations, partnerships, or
limited liability companies, it is not necessary for Bank to inquire into the
powers of Borrowers or of the officers, directors, partners, members, managers,
or agents acting or purporting to act on their behalf, and any indebtedness made
or created in reliance upon the professed exercise of such powers shall be
guaranteed hereunder.

     (13)  (a)  Guarantors, authorize Bank to verify or check any information
given by Guarantors to Bank, check Guarantors' credit references, verify
employment, and obtain credit reports.

           (b) Guarantors authorize Bank to disclose to any of Bank's affiliates
any information given by Guarantors to Bank in connection with Bank's extension
of credit to Borrowers provided that (i) such information will be used by such
affiliate only in connection with evaluating Borrowers' request or application
for a product or service offered by such affiliate and (ii) Guarantors may at
any time revoke this authorization. Such revocation shall be effective upon
actual receipt by Bank, at the address shown below or at such other address as
may have been provided to Guarantors by Bank, of written notice of such
revocation.

           (c) Guarantors acknowledge and agree that the authorizations provided
in subparagraphs (a) and (b) of-this paragraph apply to any individual general
partners of any Guarantor and to any Guarantor's spouse and any such general
partner's spouse if such Guarantor or such general partner is married and lives
in a community property state.

     (14) Bank may, without notice to Guarantors and without affecting
Guarantors' obligations hereunder, assign the indebtedness and this Guaranty, in
whole or in part. Guarantors agree that Bank may disclose to any assignee or
purchaser, or any prospective assignee or purchaser, of all or part of the
indebtedness any and all information in Bank's possession concerning Guarantors,
this Guaranty, and any security for this Guaranty,

     (15) Guarantors agree to pay all reasonable attorneys' fees, including
allocated costs of Bank's in-house counsel, and all other costs and expenses
which may be incurred by Bank (a) in the enforcement of this Guaranty or (b) in
the preservation, protection, or enforcement of any rights of Bank in any case
commenced by or against Guarantors under the Bankruptcy Code (Title 11, United
States Code) or any similar or successor statute.

     (16) Where there is but a single Borrower, or where a single Guarantor
executes this Guaranty, then all words used herein in the plural shall be deemed
to have been used in the singular where the context and construction so require;
and when there is more than one Borrower named herein, or when this Guaranty is
executed by more than one Guarantor, the words "Borrowers" and "Guarantors"
respectively shall mean all and any one or more of them.

     (17) This Guaranty shall be governed by and construed according to the laws
of the State of California, to the jurisdiction of which the parties hereto
submit.

     (18)  (a)  Any controversy or claim between or among the parties, including
but not limited to those arising out of or relating to this Guaranty or any
agreements or instruments relating hereto or delivered in connection herewith
and any claim based on or arising from an alleged tort, shall at the request of
any party be determined by arbitration. The arbitration shall be conducted in
accordance with the United States Arbitration Act (Title 9, U.S. Code),
notwithstanding any choice of law provision in this Guaranty, and under the
Commercial Rules of the American Arbitration Association ("AAA"). The
arbitrators shall give effect to statutes of limitation in determining any
claim, except as expressly waived hereunder by Guarantors. Any controversy
concerning whether an issue is arbitrable shall be determined by the
arbitrators. Judgment upon the arbitration award may be entered in any court
having jurisdiction. The institution and maintenance of an action for judicial
relief or pursuit of a provisional or ancillary remedy shall not constitute a
waiver of the right of any party, including the plaintiff, to submit the
controversy or claim to arbitration if any other party contests such action for
judicial relief.

          (b) Notwithstanding the provisions of subparagraph (a), no controversy
or claim shall be submitted to arbitration without the consent of all parties
if, at the time of the proposed submission, such controversy or claim arises
from or relates to an obligation to Bank which is secured by real property

          (d) No provision of this paragraph shall limit the right of any party
to this Guaranty to exercise self-help remedies such as setoff, to foreclose
against or sell any real or personal property collateral or security, or to
obtain provisional or ancillary remedies from a court of competent jurisdiction
before, after, or during the pendency of any arbitration or other proceeding.
The exercise of a remedy does not waive the right of either party to resort to
arbitration or reference. At Bank's option, foreclosure under a deed of trust or
mortgage may be accomplished either by exercise of power of sale under the deed
of trust or mortgage or by judicial foreclosure.
