1.       PURPOSES.

         (a)      The purpose of the Plan is to provide a means by which
selected Employees of and Consultants to the Company and its Affiliates who are
not Officers or members of the Boards of Directors of the Company or any of its
Affiliates, may be given an opportunity to benefit from increases in value of
the stock of the Company through the granting of (i) Nonstatutory Stock Options,
(ii) stock bonuses and (iii) rights to purchase restricted stock, all as
described below. The Plan is also intended to provide a means by which the
Company may grant options to persons not previously employed by the Company as
an inducement essential to those persons' entering employment contracts with the
Company. These inducement grants may be made to persons who ultimately are
employed by the Company as Officers.

          The Company, by means of the Plan, seeks to retain the services of
persons who are now Employees of or Consultants to the Company or an Affiliate
and to provide incentives for such persons to exert maximum efforts for the
success of the Company and its Affiliates.

          The Company intends that the Stock Awards issued under the Plan shall,
in the discretion of the Board or any Committee to which responsibility for
administration of the Plan has been delegated pursuant to subsection 3(c), be
either (i) Options granted pursuant to Section 6 hereof or (ii) stock bonuses or
rights to purchase restricted stock granted pursuant to Section 7 hereof.

3(c).

         (b)      The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

                                       3.

<PAGE>

                  (1) To determine from time to time which of the persons
eligible under the Plan shall be granted Stock Awards; when and how each Stock
Award shall be granted; whether a Stock Award will be an Option, a stock bonus,
a right to purchase restricted stock, or a combination of the foregoing; the
provisions of each Stock Award granted (which need not be identical), including
the time or times when a person shall be permitted to receive stock pursuant to
a Stock Award; and the number of shares with respect to which a Stock Award
shall be granted to each such person.

                  (2) To construe and interpret the Plan and Stock Awards
granted under it, and to establish, amend and revoke rules and regulations for
its administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Stock Award Agreement,
in a manner and to the extent it shall deem necessary or expedient to make the
Plan fully effective.

                  (3) To amend the Plan or a Stock Award as provided in

acts as the Board deems necessary or expedient to promote the best interests of
the Company which are not in conflict with the provisions of the Plan.

         (c)      The Board may delegate administration of the Plan to a
committee of the Board composed of two (2) or more members (the "Committee"),
all of the members of which Committee may be, in the discretion of the Board,
Non-Employee Directors. If administration is delegated to a Committee, the
Committee shall have, in connection with the administration of the Plan, the
powers theretofore possessed by the Board, including the power to delegate to a
subcommittee any of the administrative powers the Committee is authorized to
exercise (and references in this Plan to the Board shall thereafter be to the
Committee or such a subcommittee), subject, however, to such resolutions, not
inconsistent with the provisions of the Plan, as may be adopted from time to
time by the Board. The Board may abolish the Committee at any time and revest in
the Board the administration of the Plan. In addition, notwithstanding anything
in this Section 3 to the contrary, the Board or the Committee may delegate to a
committee of one or more members of the Board the authority to grant Stock
Awards to eligible persons who are not then subject to Section 16 of the
Exchange Act.

4.       SHARES SUBJECT TO THE PLAN.

         (a)      Subject to the provisions of Section 11 relating to
adjustments upon changes in stock, the stock that may be issued pursuant to
Stock Awards shall not exceed in the aggregate four million seven hundred thirty
seven thousand eight hundred twenty six (14,737,826) shares of the Company's
Common Stock. If any Stock Award shall for any reason expire or otherwise
terminate, in whole or in part, without having been exercised in full, the stock
not acquired under such Stock Award shall revert to and again become available
for issuance under the Plan.

         (b)      The stock subject to the Plan may be unissued shares or
reacquired shares, bought on the market or otherwise.

                                       4.

<PAGE>

5.       ELIGIBILITY.

         (a)      Stock Awards may be granted only to Employees or Consultants.

         (b)      A Consultant shall not be eligible for the grant of a Stock
Award if, at the time of grant, a Form S-8 Registration Statement under the
Securities Act ("Form S-8") is not available to register either the offer or the
sale of the Company's securities to such Consultant because of the nature of the
services that the Consultant is providing to the Company, or because the
Consultant is not a natural person, or as otherwise provided by the rules
governing the use of Form S-8, unless the Company determines both (i) that such
grant (A) shall be registered in another manner under the Securities Act (e.g.,
on a Form S-3 Registration Statement) or (B) does not require registration under
the Securities Act in order to comply with the requirements of the Securities
Act, if applicable, and (ii) that such grant complies with the securities laws
of all other relevant jurisdictions.

6.       OPTION PROVISIONS.

         Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

         (a)      TERM. No Option shall be exercisable after the expiration of
ten (10) years from the date it was granted.

         (b)      PRICE. The exercise price of each Option shall be not less
than eighty-five percent (85%) of the Fair Market Value of the stock subject to
the Option on the date of grant.

         (c)      CONSIDERATION. The purchase price of stock acquired pursuant
to an Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board or the Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other common stock of the Company, (B)
according to a deferred payment arrangement (however, in the event the Company
is then incorporated in the state of Delaware, then payment of the common
stock's "par value" as defined in the Delaware General Corporation Law shall not
be made by deferred payment), or other arrangement (which may include, without
limiting the generality of the foregoing, the use of other common stock of the
Company) with the person to whom the Option is granted or to whom the Option is
transferred pursuant to subsection 6(d) or (C) in any other form of legal
consideration that may be acceptable to the Board. In the case of any deferred
payment arrangement, interest shall be compounded at least annually and shall be
charged at the minimum rate of interest necessary to avoid the treatment as
interest, under any applicable provisions of the Code, of any amounts other than
amounts stated to be interest under the deferred payment arrangement.

         (d)      TRANSFERABILITY. An Option may be transferable to the extent
provided in the Option Agreement; provided, however, that if the Option
Agreement does not specifically provide for transferability, then such Option
shall not be transferable except by will or by the laws of descent and
distribution. Notwithstanding the foregoing, the person to whom the Option

                                       5.

<PAGE>

is granted may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the
death of the Optionee, shall thereafter be entitled to exercise the Option.

         (e)      VESTING. The total number of shares of stock subject to an
Option may, but need not, be allotted in periodic installments (which may, but
need not, be equal). The Option Agreement may provide that from time to time
during each of such installment periods, the Option may become exercisable
("vest") with respect to some or all of the shares allotted to that period, and
may be exercised with respect to some or all of the shares allotted to such
period and/or any prior period as to which the Option became vested but was not
fully exercised. The Option may be subject to such other terms and conditions on
the time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The provisions of this
subsection 6(e) are subject to any Option provisions governing the minimum
number of shares as to which an Option may be exercised.

         (f)      TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
CONSULTANT. In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
disability), the Optionee may exercise the Option (to the extent that the
Optionee was entitled to exercise it as of the date of termination) but only
within such period of time ending on the earlier of (i) the date ninety (90)
days following the termination of the Optionee's Continuous Status as an
Employee, Director or Consultant (or such longer period as specified in the
Option Agreement), or (ii) the expiration of the term of the Option as set forth
in the Option Agreement; provided, however, if the Optionee is terminated for
cause, then the Option shall terminate on the date Optionee's Continuous Status
as an Employee, Director or Consultant ceases. If, at the date of termination,
the Optionee is not entitled to exercise the entire Option, the shares covered
by the unexercisable portion of the Option shall revert to and again become
available for issuance under the Plan. If, after termination, the Optionee does
not exercise the Option within the time specified in the Option Agreement, the
Option shall terminate, and the shares covered by such Option shall revert to
and again become available for issuance under the Plan.

         An Optionee's Option Agreement may also provide that if the exercise of
the Option following the termination of the Optionee's Continuous Status as an
Employee, Director, or Consultant (other than upon the Optionee's death or
disability) would result in liability under Section 16(b) of the Exchange Act,
then the Option shall terminate on the earlier of (i) the expiration of the term
of the Option set forth in the Option Agreement, or (ii) the tenth (10th) day
after the last date on which such exercise would result in such liability under
Section 16(b) of the Exchange Act. Finally, an Optionee's Option Agreement may
also provide that if the exercise of the Option following the termination of the
Optionee's Continuous Status as an Employee, Director or Consultant (other than
upon the Optionee's death or disability) would be prohibited at any time solely
because the issuance of shares would violate the registration requirements under
the Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in the first paragraph of this
subsection 6(f), or (ii) the expiration of a period of three (3) months after
the termination of the Optionee's Continuous Status as an Employee, Director or
Consultant during which the exercise of the Option would not be in violation of
such registration requirements.

                                       6.

<PAGE>

         (g)      DISABILITY OF OPTIONEE. In the event an Optionee's Continuous
Status as an Employee, Director or Consultant terminates as a result of the
Optionee's disability, the Optionee may exercise the Option (to the extent that
the Optionee was entitled to exercise it as of the date of termination), but
only within such period of time ending on the earlier of (i) the date twelve
(12) months following such termination (or such longer or shorter period
specified in the Option Agreement), or (ii) the expiration of the term of the
Option as set forth in the Option Agreement. If, at the date of termination, the
Optionee is not entitled to exercise the entire Option, the shares covered by
the unexercisable portion of the Option shall revert to and again become
available for issuance under the Plan. If, after termination, the Optionee does
not exercise the Option within the time specified herein, the Option shall
terminate, and the shares covered by such Option shall revert to and again
become available for issuance under the Plan.

         (h)      DEATH OF OPTIONEE. In the event of the death of an Optionee
during, or within a period specified in the Option Agreement after the
termination of, the Optionee's Continuous Status as an Employee, Director or
Consultant, the Option may be exercised (to the extent the Optionee was entitled
to exercise the Option as of the date of death) by the Optionee's estate, by a
person who acquired the right to exercise the Option by bequest or inheritance
or by a person designated to exercise the option upon the Optionee's death
pursuant to subsection 6(d), but only within the period ending on the earlier of
(i) the date eighteen (18) months following the date of death (or such longer or
shorter period specified in the Option Agreement), or (ii) the expiration of the
term of such Option as set forth in the Option Agreement. If, at the time of
death, the Optionee was not entitled to exercise the entire Option, the shares
covered by the unexercisable portion of the Option shall revert to and again
become available for issuance under the Plan. If, after death, the Option is not
exercised within the time specified herein, the Option shall terminate, and the
shares covered by such Option shall revert to and again become available for
issuance under the Plan.

7.       TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

         Each stock bonus or restricted stock purchase agreement shall be in
such form and shall contain such terms and conditions as the Board or the
Committee shall deem appropriate. The terms and conditions of stock bonus or
restricted stock purchase agreements may change from time to time, and the terms
and conditions of separate agreements need not be identical, but each stock
bonus or restricted stock purchase agreement shall include (through
incorporation of provisions hereof by reference in the agreement or otherwise)
the substance of each of the following provisions as appropriate:

         (a)      PURCHASE PRICE. The purchase price under each restricted stock
purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such Stock Award Agreement, but in no event shall the
purchase price be less than eighty-five percent (85%) of the stock's Fair Market
Value on the date such Stock Award is made. Notwithstanding the foregoing, the
Board or the Committee may determine that eligible participants in the Plan may
be awarded stock pursuant to a stock bonus agreement in consideration for past
services actually rendered to the Company or for its benefit.

         (b)      TRANSFERABILITY. Rights under a stock bonus or restricted
stock purchase agreement shall be transferable only by will or the laws of
descent and distribution, so long as

                                       7.

<PAGE>

stock awarded under such Stock Award Agreement remains subject to the terms of
the agreement.

         (c)      CONSIDERATION. The purchase price of stock acquired pursuant
to a stock purchase agreement shall be paid either: (i) in cash at the time of
purchase; (ii) at the discretion of the Board or the Committee, according to a
deferred payment arrangement (however, in the event the Company is then
incorporated in the state of Delaware, then payment of the common stock's "par
value" as defined in the Delaware General Corporation Law shall not be made by
deferred payment), or other arrangement with the person to whom the stock is
sold; or (iii) in any other form of legal consideration that may be acceptable
to the Board or the Committee in its discretion. Notwithstanding the foregoing,
the Board or the Committee to which administration of the Plan has been
delegated may award stock pursuant to a stock bonus agreement in consideration
for past services actually rendered to the Company or for its benefit.

         (d)      VESTING. Shares of stock sold or awarded under the Plan may,
but need not, be subject to a repurchase option in favor of the Company in
accordance with a vesting schedule to be determined by the Board or the
Committee.

         (e)      TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
CONSULTANT. In the event a Participant's Continuous Status as an Employee,
Director or Consultant terminates, the Company may repurchase or otherwise
reacquire any or all of the shares of stock held by that person which have not
vested as of the date of termination under the terms of the stock bonus or
restricted stock purchase agreement between the Company and such person.

8.       COVENANTS OF THE COMPANY.

         (a)      During the terms of the Stock Awards, the Company shall keep
available at all times the number of shares of stock required to satisfy such
Stock Awards.

         (b)      The Company shall seek to obtain from each regulatory
commission or agency having jurisdiction over the Plan such authority as may be
required to issue and sell shares of stock upon exercise of the Stock Award;
provided, however, that this undertaking shall not require the Company to
register under the Securities Act either the Plan, any Stock Award or any stock
issued or issuable pursuant to any such Stock Award. If, after reasonable
efforts, the Company is unable to obtain from any such regulatory commission or
agency the authority which counsel for the Company deems necessary for the
lawful issuance and sale of stock under the Plan, the Company shall be relieved
from any liability for failure to issue and sell stock upon exercise of such
Stock Awards unless and until such authority is obtained.

9.       USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to Stock Awards shall
constitute general funds of the Company.

10.      MISCELLANEOUS.

         (a)      The Board shall have the power to accelerate the time at which
a Stock Award may first be exercised or the time during which a Stock Award or
any part thereof will vest

                                       8.

<PAGE>

pursuant to subsection 6(e) or 7(d), notwithstanding the provisions in the Stock
Award stating the time at which it may first be exercised or the time during
which it will vest.

         (b)      Neither an Employee nor a Consultant nor any person to whom a
Stock Award is transferred under subsection 6(d) or 7(b) shall be deemed to be
the holder of, or to have any of the rights of a holder with respect to, any
shares subject to such Stock Award unless and until such person has satisfied
all requirements for exercise of the Stock Award pursuant to its terms.

         (c)      Nothing in the Plan or any instrument executed or Stock Award
granted pursuant thereto shall confer upon any Employee or Consultant or other
holder of Stock Awards any right to continue in the employ of the Company or any
Affiliate (or to continue serving as a Consultant) or shall affect the right of
the Company or any Affiliate to terminate the employment of any Employee with or
without cause or the right to terminate the relationship of any Consultant
subject to the terms of such Consultant's agreement with the Company or any
Affiliate.

         (d)      The Company may require any person to whom a Stock Award is
granted, or any person to whom a Stock Award is transferred pursuant to
subsection 6(d) or 7(b), as a condition of exercising or acquiring stock under
any Stock Award, (1) to give written assurances satisfactory to the Company as
to such person's knowledge and experience in financial and business matters
and/or to employ a purchaser representative reasonably satisfactory to the
Company who is knowledgeable and experienced in financial and business matters,
and that he or she is capable of evaluating, alone or together with the
purchaser representative, the merits and risks of exercising the Stock Award;
and (2) to give written assurances satisfactory to the Company stating that such
person is acquiring the stock subject to the Stock Award for such person's own
account and not with any present intention of selling or otherwise distributing
the stock. The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (i) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award has been registered under
a then currently effective registration statement under the Securities Act, or
(ii) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.

         (e)      To the extent provided by the terms of a Stock Award
Agreement, the person to whom a Stock Award is granted may satisfy any federal,
state or local tax withholding obligation relating to the exercise or
acquisition of stock under a Stock Award by any of the following means or by a
combination of such means: (1) tendering a cash payment; (2) authorizing the

11.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a)      If any change is made in the stock subject to the Plan, or
subject to any Stock Award (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan will be appropriately
adjusted in the type(s) and maximum number of securities subject to the Plan
pursuant to subsection 4(a) and the outstanding Stock Awards will be
appropriately adjusted in the type(s) and number of securities and price per
share of stock subject to such outstanding Stock Awards. Such adjustments shall
be made by the Board or the Committee, the determination of which shall be
final, binding and conclusive. (The conversion of any convertible securities of
the Company shall not be treated as a "transaction not involving the receipt of
consideration by the Company.")

         (b)      In the event of a Change in Control (as defined herein): (i)
any surviving corporation or acquiring corporation shall assume any Stock Awards
outstanding under the Plan or shall substitute similar stock awards (including
an award to acquire the same consideration paid to the stockholders in a Change
in Control) for those outstanding under the Plan, or (ii) in the event any
surviving corporation or acquiring corporation refuses to assume such Stock
Awards or to substitute similar stock awards for those outstanding under the
Plan, (A) with respect to Stock Awards held by persons then performing services
as Employees, Directors or Consultants, the vesting (and, if applicable, the
exercisability) of such Stock Awards shall be accelerated prior to such event
and the Stock Awards terminated if not exercised at or prior to such event, and
(B) with respect to any other Stock Awards outstanding under the Plan, such
Stock Awards shall be terminated if not exercised prior to such event.

         (c)      For purposes of the Plan, a "Change in Control" shall mean:
(1) a dissolution, liquidation or sale of all or substantially all of the assets
of the Company; (2) a merger or consolidation in which the Company is not the
surviving corporation; (3) a reverse merger in which the Company is the
surviving corporation but the shares of the Company's common stock outstanding
immediately preceding the merger are converted by virtue of the merger into
other property, whether in the form of securities, cash or otherwise; or (4) the
acquisition by any person, entity or group within the meaning of Section 13(d)
or 14(d) of the Exchange Act, or any comparable successor provisions (excluding
any employee benefit plan, or related trust, sponsored or maintained by the
Company or any Affiliate of the Company) of the beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable
successor rule) of securities of the Company representing at least fifty percent
(50%) of the combined voting power entitled to vote in the election of
directors.

12.      AMENDMENT OF THE PLAN AND STOCK AWARDS.

         (a)      The Board at any time, and from time to time, may amend the
Plan. However, except as provided in Section 11 relating to adjustments upon
changes in stock, no amendment shall be effective unless approved by the
stockholders of the Company to the extent stockholder approval is necessary for
the Plan to satisfy the requirements of Section 422 of the Code, Rule 16b-3
under the Exchange Act or any Nasdaq or securities exchange listing
requirements. The

                                      10.

Board may in its sole discretion submit any other amendment to the Plan for
stockholder approval.

         (b)      Rights and obligations under any Stock Award granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the person to whom the Stock Award was
granted and (ii) such person consents in writing.

         (c)      The Board at any time, and from time to time, may amend the
terms of any one or more Stock Award; provided, however, that the rights and
obligations under any Stock Award shall not be impaired by any such amendment
unless (i) the Company requests the consent of the person to whom the Stock
Award was granted and (ii) such person consents in writing.

13.      TERMINATION OR SUSPENSION OF THE PLAN.

         (a)      The Board may suspend or terminate the Plan at any time. No
Stock Awards may be granted under the Plan while the Plan is suspended or after
it is terminated.

         (b)      Rights and obligations under any Stock Award granted while the
Plan is in effect shall not be impaired by suspension or termination of the
Plan, except with the written consent of the person to whom the Stock Award was
granted.

Re: Employment Terms

Dear Doug:

Terayon Communication Systems, Inc. (hereafter referred to as "Terayon" or "The
Company") is pleased to offer you the position of Chief Operating Officer on the
following terms.

You will work at 4988 Great America Parkway in Santa Clara, California and
report to Dr. Zaki Rakib, the Company's Chief Executive Officer. As the Chief
Operating Officer of the Company, you will have the following organizations
reporting to you, directly or indirectly: sales, marketing, product management,
customer service and support, manufacturing operations and engineering but
excluding the Company's CTO.

Your base compensation will be $300,000, less payroll deductions and all
required withholdings. You will be paid semi-monthly and you will be eligible
for the standard Company benefits. Details about these benefit plans will be
available for your review upon request. You will be eligible to participate in
Terayon's management incentive plan. Your target incentive compensation for
fiscal 2003 is 50% of your base earnings.

Pursuant to Terayon's stock option plan and subject to the approval of Terayon's
Board of Directors, you will receive an option to purchase 500,000 shares of
Terayon's Common Stock. The exercise price per share of the stock granted
subject to this option will be equal to the fair market value of Terayon's
Common Stock on the date of grant as determined by the Board of Directors. Your
option grant will vest over a four (4) year period, with 1/4th or 25% of the
total option shares vesting on the first anniversary of your employment start
date with the Company and 1/48th of the total option shares vesting monthly
thereafter.

As a Terayon employee, you will be expected to abide by Company rules and
regulations and to sign and comply with a Proprietary Information and Inventions
Agreement that prohibits unauthorized use or disclosure of proprietary
information of Terayon.

Normal working hours are from 8:00am to 5:00pm, Monday through Friday. As an
exempt salaried employee, you will be expected to work additional hours as
required by the nature of your work assignments.

You may terminate your employment with Terayon at any time and for any reason
whatsoever simply by notifying Terayon. Likewise, your employment with Terayon
is at will, and Terayon may terminate your employment at any time and for any
reason whatsoever, with or without cause or advance notice. This at-will
employment relationship cannot be changed except in a written format signed by
the Chief Executive Officer or the President of Terayon.

<PAGE>

Notwithstanding the at will employment relationship between you and Terayon,
Terayon agrees that, in the event your employment with the Company is terminated
by the Company for any reason other than for Cause, as hereinafter defined, or
in the case of Constructive Termination, as hereinafter defined, then you will
be entitled to a severance payment equal to twelve (12) months of base salary,
which amount will be payable in a lump sum or semi-monthly over the twelve (12)
month period, in the Company's sole discretion. In addition to this severance
payment, in the event of the foregoing, the Company will provide you with
continuation of your benefits, at the Company's expense, for the duration of
such twelve (12) month period.

For purposes of the foregoing, "Cause" is defined as (i) the commission by you
of a crime against the Company; (ii) the conviction of you of a crime involving
moral turpitude; (iii) the willful failure by you to perform your duties as
Chief Operating Officer of the Company, as determined by the Board of Directors,
which failure continues for more than five (5) business days after notice is
given and (iv) the engagement by you in misconduct that is demonstrably and
materially injurious to the Company and its affiliates taken as a whole, as
determined by the Board of Directors.

Moreover, for purposes of the foregoing, "Constructive Termination" is defined
as (i) a material and adverse change in your duties as Chief Operating Officer,
your reporting relationships and your location of employment (i.e., Santa Clara,
California) and (ii) an adverse change in your title or base salary.

The employment terms in this letter supersede any other agreements or promises
made to you by anyone, whether oral or written. No modification of or amendment
to this letter, nor any waiver of any rights under this letter, will be
effective unless in writing and signed by Terayon. As required by law, this
offer is subject to satisfactory proof of your right to work in the United
States.

Please sign and date this letter, and return it by July 3, 2003, if you wish to
accept employment at Terayon under the terms described above. We would like you
to start on or before July 14, 2003.

We look forward to your favorable reply and to a productive and enjoyable work
relationship.

Sincerely,

/s/ Zaki Rakib

Zaki Rakib
Chief Executive Officer
