Item 3. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

     The following documents filed by Terayon Communication Systems, Inc. (the
"Company") with the Securities and Exchange Commission are incorporated by
reference into this Registration Statement:

     (a)  The Company's latest annual report on Form 10-K filed pursuant to
Sections 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), or either (1) the Company's latest prospectus filed pursuant to
Rule 424(b) under the Securities Act of 1933, as amended (the "Act"), that
contains audited financial statements for the Company's latest fiscal year for
which such statements have been filed, or (2) the Company's effective
registration statement on Form 10 or 20-F filed under the Exchange Act
containing audited financial statements for the Company's latest fiscal year.

     (b)  All other reports filed pursuant to Sections 13(a) or 15(d) of the
Exchange Act since the end of the fiscal year covered by the annual reports, the
prospectus or the registration statement referred to in (a) above.

     (c)  The description of the Company's Common Stock which is contained in a
registration statement filed under the Exchange Act, including any amendment or
report filed for the purpose of updating such description.

     All reports and other documents subsequently filed by the Company pursuant
to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act prior to the filing
of a post-effective amendment which indicates that all securities offered have
been sold or which deregisters all securities then remaining unsold, shall be
deemed to be incorporated by reference herein and to be a part of this
registration statement from the date of the filing of such reports and
documents.

Item 4. DESCRIPTION OF SECURITIES

     Not applicable.

Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

     The validity of the Common Stock offered hereby will be passed upon for the
Company by Cooley Godward LLP ("Cooley Godward"), San Francisco, California.  As
of the date of this Registration Statement, certain partners and associates of
Cooley Godward own through investment partnerships an aggregate of 36,668 shares
of Common Stock of the Company.

Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Under Section 145 of the Delaware General Corporation Law, the Company has
broad powers to indemnify its directors and officers against liabilities they
may incur in such capacities, including liabilities under the Securities Act.
The Company's Bylaws require the Company to indemnify its directors and
executive officers, and permit the Company to indemnify its other officers,
employees and other agents, to the extent permitted by Delaware law.  Under the
Company's Bylaws, indemnified parties are entitled to the fullest extent not
prohibited by law.  The Bylaws also require the Company to advance litigation
expenses in the case of stockholder derivative actions or other actions, against
an undertaking by the indemnified party to repay such advances if it is
ultimately determined that the indemnified party is not entitled to
indemnification.

     The Company has entered into indemnity agreements with each of its
directors and executive officers.  Such indemnity agreements contain provisions
which are in some respects broader than the specific indemnification provisions
contained in Delaware law.

     In addition, the Amended and Restated Certificate of Incorporation provides
that a director of the Company shall not be personally liable to the Company or
its stockholders for monetary damages for any breach of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv)
for any transaction from which the director derived an improper personal
benefit.  If the Delaware General Corporation Law is amended to authorize
corporate action further eliminating or limiting the personal liability of
directors, then the liability of a director shall be eliminated or limited to
the fullest extent permitted by the Delaware General Corporation Law, as so
amended.

Item 10. UNDERTAKINGS

                                        
1.   The undersigned registrant hereby undertakes:

     (a)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

          (i)   To include any prospectus required by Section 10(a)(3) of the
Securities Act;

          (ii)  To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate, represent
a fundamental change in the information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) ((S) 230.424(b) of this
chapter) if, in the aggregate, the changes in volume and price represent no more
than a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration statement;

          (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

     Provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the issuer pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference herein.

     (b)  That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (c)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

2.   The undersigned registrant hereby undertakes that, for purposes of
     determining any liability under the Securities Act, each filing of the
     registrant's annual report pursuant to Section 13(a) or Section 15(d) of
     the Exchange Act (and, where applicable, each filing of an employee benefit
     plan's annual report pursuant to section 15(d) of the Exchange Act) that is
     incorporated by reference in the Registration Statement shall be deemed to
     be a new registration statement relating to the securities offered herein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

3.   Insofar as indemnification for liabilities arising under the Securities Act
     may be permitted to directors, officers and controlling persons of the
     registrant pursuant to the foregoing provisions, or otherwise, the
     registrant has been advised that in the opinion of the Securities and
     Exchange Commission such indemnification is against public policy as
     expressed in the Securities Act and is, therefore, unenforceable.  In the
     event that a claim for indemnification against such liabilities (other than
     the payment by the registrant of expenses incurred or paid by a director,
     officer or controlling person of the registrant in the successful defense
     of any action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     registrant will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is against
     public policy as expressed in the Securities Act and will be governed by
     the final adjudication of such issue.

                                       I.

     The name of this corporation is Terayon Communication Systems, Inc.

                                      II.

     The address of the registered office of the corporation in the State of
Delaware is 1013 Centre Road, City of Wilmington, 19805, County of New Castle
and the name of the registered agent of the corporation in the State of Delaware
at such address is Corporation Service Company.

                                      III.

     The purpose of this corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
the State of Delaware.

                                      IV.

     This corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares which the corporation is authorized to issue is Thirty-Five Million
(35,000,000) shares. Thirty Million (30,000,000) shares shall be Common Stock,
each having a par value of one tenth of one cent ($.001). Five Million
(5,000,000) shares shall be Preferred Stock, each having a par value of one
tenth of one cent ($.001).

     The Preferred Stock may be issued from time to time in one or more series.
The Board of Directors is hereby authorized, by filing a certificate (a
"Preferred Stock Designation") pursuant to the Delaware General Corporation Law,
to fix or alter from time to time the designation, powers, preferences and
rights of the shares of each such series and the qualifications, limitations or
restrictions of any wholly unissued series of Preferred Stock, and to establish
from time to time the number of shares constituting any such series or any of
them; and to increase or decrease the number of shares of any series subsequent
to the issuance of shares of that series, but not below the number of shares of
such series then outstanding.  In case the number of shares of any series shall
be decreased in accordance with the foregoing sentence, the shares constituting
such decrease shall resume the status that they had prior to the adoption of the
resolution originally fixing the number of shares of such series.

                                      V.

    A.   For the management of the business and for the conduct of the affairs
of the Corporation, and in further definition, limitation and regulation of the
powers of the Corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

         (1)  The management of the business and the conduct of the affairs of
the Corporation shall be vested in its Board of Directors. The number of
directors which shall constitute the whole 

                                       2
<PAGE>
 
Board of Directors shall be fixed exclusively by one or more resolutions adopted
by the Board of Directors.

         (2)  Subject to the rights of the holders of any series of Preferred
Stock to elect additional directors under specified circumstances, and to any
restrictions or limitations of applicable law, following the closing of the
initial public offering pursuant to an effective registration statement under
the Securities Act of 1933, as amended, covering the offer and sale of Common
Stock to the public (the "Initial Public Offering"), the directors shall be
divided into three classes designated as Class I, Class II and Class III,
respectively. Directors shall be assigned to each class in accordance with a
resolution or resolutions adopted by the Board of Directors. At the first annual
meeting of stockholders following the closing of the Initial Public Offering,
the term of office of the Class I directors shall expire and Class I directors
shall be elected for a full term of three years. At the second annual meeting of
stockholders following the Closing of the Initial Public Offering, the term of
office of the Class II directors shall expire and Class II directors shall be
elected for a full term of three years. At the third annual meeting of
stockholders following the Closing of the Initial Public Offering, the term of
office of the Class III directors shall expire and Class III directors shall be
elected for a full term of three years. At each succeeding annual meeting of
stockholders, directors shall be elected for a full term of three years to
succeed the directors of the class whose terms expire at such annual meeting.

     Notwithstanding the foregoing provisions of this Article, each director
shall serve until his successor is duly elected and qualified or until his
death, resignation or removal. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

         (3)  Subject to the rights of the holders of any series of Preferred
Stock, the Board of Directors or any individual director may be removed from
office at any time (i) with cause by the affirmative vote of the holders of a
majority of the voting power of all the then-outstanding shares of voting stock
of the Corporation, entitled to vote at an election of directors (the "Voting
Stock") or (ii) without cause by the affirmative vote of the holders of at least
sixty-six and two-thirds percent (66 2/3%) of the voting power of all the then-
outstanding shares of the Voting Stock.

         (4)  Subject to the rights of the holders of any series of Preferred
Stock, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors, shall,
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by the stockholders, except as
otherwise provided by law, be filled only by the affirmative vote of a majority
of the directors then in office, even though less than a quorum of the Board of
Directors, and not by the stockholders. Any director elected in accordance with
the preceding sentence shall hold office for the remainder of the full term of
the director for which the vacancy was created or occurred and until such
director's successor shall have been elected and qualified.

         (5)  In the event that Section 2115(a) of the California Corporations
Code is applicable to this corporation, then the following shall apply:

              (a)  Every stockholder entitled to vote in any election of
directors of this corporation may cumulate such stockholder's votes and give one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which the stockholder's shares are
otherwise entitled, or distribute the stockholder's votes on the same principle
among as many candidates as such stockholder thinks fit;

                                       3
<PAGE>
 
              (b)  No stockholder, however, may cumulate such stockholder's
votes for one or more candidates unless (i) the names of such candidates have
been properly placed in nomination, in accordance with the Bylaws of the
Corporation, prior to the voting, (ii) the stockholder has given advance notice
to the corporation of the intention to cumulative votes pursuant to the Bylaws,
and (iii) the stockholder has given proper notice to the other stockholders at
the meeting, prior to voting, of such stockholder's intention to cumulate such
stockholder's votes; and

              (c)  If any stockholder has given proper notice, all stockholders
may cumulate their votes for any candidates who have been properly placed in
nomination. The candidates receiving the highest number of votes of the shares
entitled to be voted for them up to the number of directors to be elected by
such shares shall be declared elected.

     B.  (1)  Subject to paragraph (h) of Section 43 of the Bylaws, the Bylaws
may be altered or amended or new Bylaws adopted by the affirmative vote of at
least sixty-six and two-thirds percent (66-2/3%) of the voting power of all of
the then-outstanding shares of the Voting Stock. The Board of Directors shall
also have the power to adopt, amend, or repeal Bylaws.

         (2)  The directors of the Corporation need not be elected by written
ballot unless the Bylaws so provide.

         (3)  No action shall be taken by the stockholders of the Corporation
except at an annual or special meeting of stockholders called in accordance with
the Bylaws and following the closing of the Initial Public Offering no action
shall be taken by the stockholders by written consent.

         (4)  Advance notice of stockholder nominations for the election of
directors and of business to be brought by stockholders before any meeting of
the stockholders of the Corporation shall be given in the manner provided in the
Bylaws of the Corporation.

                                      VI.

     A.  A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for any breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit.  If the Delaware General Corporation Law is amended after
approval by the stockholders of this Article to authorize corporate action
further eliminating or limiting the personal liability of directors, then the
liability of a director shall be eliminated or limited to the fullest extent
permitted by the Delaware General Corporation Law, as so amended.

     B.  Any repeal or modification of this Article VI shall be prospective and
shall not affect the rights under this Article VI in effect at the time of the
alleged occurrence of any act or omission to act giving rise to liability or
indemnification.

                                     VII.

     A.  The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation, in the manner now
or hereafter prescribed by statute, 

                                       4
<PAGE>
 
except as provided in paragraph B. of this Article VII, and all rights conferred
upon the stockholders herein are granted subject to this reservation.

     B.  Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser vote
or no vote, but in addition to any affirmative vote of the holders of any
particular class or series of the Voting Stock required by law, this Certificate
of Incorporation or any Preferred Stock Designation, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting
power of all of the then-outstanding shares of the Voting Stock, voting together
as a single class, shall be required to alter, amend or repeal Articles V, VI
and VII.

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection
with the filing by Terayon Communication Systems, Inc. (the "Company") of a
Registration Statement on Form S-8 (the "Registration Statement") with the
Securities and Exchange Commission covering the offering of up to 5,505,564
shares of the Company's Common Stock, $0.001 par value, (the "Shares"),
5,405,564 shares of which will be offered pursuant to the Company's (i) 1995
Stock Option Plan (the "1995 Plan"), (ii) 1997 Equity Incentive Plan (the "1997
Plan"), (iii) 1998 Non-Employee Directors' Stock Option Plan (the "1998
Directors' Plan") and (iv) 1998 Employee Stock Purchase Plan (the "1998 Purchase
Plan") (the 1995 Plan, the 1997 Plan, the 1998 Directors' Plan and the 1998
Purchase Plan, collectively, the "Plans"), and 100,000 shares of which will be
offered pursuant to options granted outside the Plans.

In connection with this opinion, we have examined the Registration Statement and
related Prospectus, your Certificate of Incorporation and Bylaws, as amended,
and such other documents, records, certificates, memoranda and other instruments
as we deem necessary as a basis for this opinion.  We have assumed the
genuineness and authenticity of all documents submitted to us as originals, the
conformity to originals of all documents submitted to us as copies thereof, and
the due execution and delivery of all documents where due execution and delivery
are a prerequisite to the effectiveness thereof.

On the basis of the foregoing, and in reliance thereon, we are of the opinion
that the Shares, when sold and issued in accordance with the Plans, the
Registration Statement and related Prospectus, will be validly issued, fully
paid, and nonassessable (except as to shares issued pursuant to certain deferred
payment arrangements, which will be fully paid and nonassessable when such
deferred payments are made in full).

We consent to the filing of this opinion as an exhibit to the Registration
Statement.

Very truly yours,

Cooley Godward llp

($1,000), payment pursuant to the deferred payment alternative as described in
paragraph 2(c) hereof; or

                (v)   Payment by a combination of the methods of payment
permitted by subparagraph 2(b)(i) through 2(b)(iv) above.

          (c)   In the event that you elect to make payment of the exercise
price pursuant to the deferred payment alternative:

                (i)   Not less than twenty-five percent (25%) of the aggregate
exercise price shall be due at the time of exercise, not less than twenty-five
percent (25%) of said exercise price, plus accrued interest, shall be due each
year after the date of exercise, and final payment of the remainder of the
exercise price, plus accrued interest, shall be due three (3) years from date of
exercise or, at the Company's election, upon termination of your employment with
the Company or an affiliate;

                (ii)  Interest shall be payable 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 portion of any
amounts other than amounts stated to be interest under the deferred payment
arrangement; and

                (iii) In order to elect the deferred payment alternative, you
must, as a part of your written notice of exercise, give notice of the election
of this payment alternative and, in order to secure the payment of the deferred
exercise price to the Company hereunder, if the Company so requests, you must
tender to the Company a promissory note and a security agreement covering the
purchased shares, both in form and substance satisfactory to the Company, or
such other or additional documentation as the Company may request.

     3.   This option may not be exercised for any number of shares which would
require the issuance of anything other than whole shares.

     4.   Notwithstanding anything to the contrary contained herein, this option
may not be exercised unless the shares issuable upon exercise of this option are
then registered under the Act or, if such shares are not then so registered, the
Company has determined that such exercise and issuance would be exempt from the
registration requirements of the Act.

     5.   The term of this option commences on the date hereof and, unless
sooner terminated as set forth below or in the Plan, terminates on
___________________________ (which date shall be no 

                                       2
<PAGE>
 
more than ten (10) years from date this option is granted). In no event may this
option be exercised on or after the date on which it terminates. This option
shall terminate prior to the expiration of its term as follows: three (3) months
after the termination of your employment with the Company or an affiliate of the
Company (as defined in the Plan) for any reason or for no reason unless:

          (a)   such termination of employment is due to your disability, in
which event the option shall terminate on the earlier of the termination date
set forth above or twelve (12) months following such termination of employment;
or

          (b)   such termination of employment is due to your death, in which
event the option shall terminate on the earlier of the termination date set
forth above or eighteen (18) months after your death; or

          (c)   during any part of such three (3) month period the option is not
exercisable solely because of the condition set forth in paragraph 5 above, in
which event the option shall not terminate until the earlier of the termination
date set forth above or until it shall have been exercisable for an aggregate
period of three (3) months after the termination of employment; or

          (d)   exercise of the option within three (3) months after termination
of your employment with the Company or with an affiliate would result in
liability under section 16(b) of the Securities Exchange Act of 1934, in which
case the option will terminate on the earlier of (i) the termination date set
forth above, (ii) the tenth (10th) day after the last date upon which exercise
would result in such liability or (iii) six (6) months and ten (10) days after
the termination of your employment with the Company or an affiliate.

     However, this option may be exercised following termination of employment
only as to that number of shares as to which it was exercisable on the date of
termination of employment under the provisions of paragraph 1 of this option.
Termination of employment, for ISO purposes, includes cessation of employment,
but continued service as a director or consultant (notwithstanding that your
continuous status will not have terminated for purpose of this Stock Option
Agreement or the Plan).

     6.   (a)   This option may be exercised, to the extent specified above, by
delivering a notice of exercise (in a form designated by the Company) together
with the exercise price to the Secretary of the Company, or to such other person
as the Company may designate, during regular business hours, together with such
additional documents as the Company may then require pursuant to subparagraph
6(f) of the Plan.

          (b)   By exercising this option you agree that:

                (i)   the Company may require you to enter an arrangement
providing for the payment by you to the Company of any tax withholding
obligation of the Company arising by reason of (1) the exercise of this option;
(2) the lapse of any substantial risk of forfeiture to which the shares are
subject at the time of exercise; or (3) the disposition of shares acquired upon
such exercise;

                (ii)  you will notify the Company in writing within fifteen (15)
days after the date of any disposition of any of the shares of the Common Stock
issued upon exercise of this option that occurs within two (2) years after the
date of this option grant or within one (1) year after such shares of Common
Stock are transferred upon exercise of this option; and

                                       3
<PAGE>
 
                (iii) the Company (or a representative of the underwriters) may,
in connection with the first underwritten registration of the offering of any
securities of the Company under the Act, require that you not sell or otherwise
transfer or dispose of any shares of Common Stock or other securities of the
Company during such period (not to exceed one hundred eighty (180) days)
following the effective date (the "Effective Date") of the registration
statement of the Company filed under the Act as may be requested by the Company
or the representative of the underwriters. For purposes of this restriction you
will be deemed to own securities which (i) are owned directly or indirectly by
you, including securities held for your benefit by nominees, custodians, brokers
or pledgees; (ii) may be acquired by you within sixty (60) days of the Effective
Date; (iii) are owned directly or indirectly, by or for your brothers or sisters
(whether by whole or half blood) spouse, ancestors and lineal descendants; or
(iv) are owned, directly or indirectly, by or for a corporation, partnership,
estate or trust of which you are a shareholder, partner or beneficiary, but only
to the extent of your proportionate interest therein as a shareholder, partner
or beneficiary thereof. You further agree that the Company may impose stop-
transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such period.

     7.   This option is not transferable, except by will or by the laws of
descent and distribution, and is exercisable during your life only by you.  By
delivering written notice to the Company, in a form satisfactory to the Company,
you may designate a third party who, in the event of your death, shall
thereafter be entitled to exercise this option.

     8.   This option is not an employment contract and nothing in this option
shall be deemed to create in any way whatsoever any obligation on your part to
continue in the employ of the Company, or of the Company to continue your
employment with the Company.

     9.   Any notices provided for in this option or the Plan shall be given in
writing and shall be deemed effectively given upon receipt or, in the case of
notices delivered by the Company to you, five (5) days after deposit in the
United States mail, postage prepaid, addressed to you at the address specified
below or at such other address as you hereafter designate by written notice to
the Company.

     10.  This option is subject to all the provisions of the Plan, a copy of
which is attached hereto and its provisions are hereby made a part of this
option, including without limitation the provisions of paragraph 6 of the Plan
relating to option provisions, and is further subject to all interpretations,
amendments, rules and regulations which may from time to time be promulgated and
adopted pursuant to the Plan.  In the event of any conflict between the
provisions of this option and those of the Plan, the provisions of the Plan
shall control.

     THIS AGREEMENT is made by and between TERAYON COMMUNICATION SYSTEMS, INC.,

                                 WITNESSETH:

     WHEREAS, Purchaser holds an incentive/non-statutory stock option to
purchase shares of common stock of the Corporation pursuant to the Corporation's
1995 Stock Option Plan (the "Plan") which Purchaser desires to exercise; and

     WHEREAS, Purchaser wishes to take advantage of the early exercise provision
of his option and therefore to enter into this Agreement;

     NOW, THEREFORE, IT IS AGREED between the parties as follows:

     1.   Purchaser hereby agrees to purchase from the Corporation, and the
Corporation hereby agrees to sell to Purchaser, an aggregate of _______ shares

mutually agree upon in writing.

     At the closing, Purchaser shall deliver three (3) stock assignments in the
form of Exhibit B, duly endorsed (with date and number of shares left blank),
joint escrow instructions (the "Joint Escrow Instructions") in the form of
Exhibit C, duly executed by Purchaser, and the total exercise price (including
an executed Note in the form of Exhibit E if a portion of the total exercise
price is to be paid by promissory note) and an executed pledge agreement in the
form of 

___________________________
/1/  Shares must meet the public trading requirements set forth in the option.
Shares must be valued in accordance with the terms of the option being
exercised, must have been owned for the minimum period required in the option,
and must be owned free and clear of any liens, claims, encumbrances or security
interests.  Certificates must be endorsed or accompanied by an executed
assignment separate from certificate.

                                       9
<PAGE>
 
Exhibit F (the "Pledge Agreement") under which all shares of the Stock
acquired by Note shall be pledged as collateral security for the payment of the
indebtedness represented by the Note; and including endorsed certificates
representing the appropriate number of shares of the Corporation's common stock
if a portion of the total exercise price is to be paid by common stock.

     At the closing or as soon thereafter as practicable, the Corporation shall
deliver to the Escrow Agent (as defined in paragraph 8 below) share certificates
for all of the Stock that is to be subject to the Purchase Option (as defined in
paragraph 2 below), and shall deliver share certificates to Purchaser for all of
the Stock, if any, that is not to be subject to the Purchase Option or the
Pledge Agreement.  The certificates for all of the Stock that is subject to the
Pledge Agreement but not the Purchase Option shall be retained by the
Corporation as security pursuant to the Pledge Agreement.

     2.   In accordance with the provisions of section 408(b) of the California
General Corporation Law, the Stock to be purchased by Purchaser pursuant to this
Agreement shall be subject to the following option ("Purchase Option"):

          (a)   In the event that Purchaser shall cease to be an employee of the
Corporation for any reason (including his death), or no reason, with or without
cause, the Purchase Option may be exercised.  The Corporation shall have the
right at any time within sixty (60) days after such cessation of employment to
purchase from Purchaser or his personal representative, as the case may be, at
the price per share paid by Purchaser pursuant to this Agreement ("Option
Price"), up to but not exceeding the number of shares of the Stock set forth on
Exhibit A hereto which is incorporated herein by this reference.

          (b)   In addition, and without limiting the foregoing Purchase Option,
if at any time during the term of the Purchase Option, there occurs:  (a) a
dissolution or liquidation of the Corporation; (b) a merger or consolidation
involving the Corporation in which the Corporation is not the surviving
corporation; (c) a reverse merger in which the Corporation is the surviving
corporation but the shares of the Corporation's common stock outstanding
immediately preceding the merger are converted by virtue of the merger into
other property, whether in the form of other securities, cash or otherwise; or
(d) any other capital reorganization in which more than fifty percent (50%) of
the shares of the Corporation entitled to vote are exchanged, then:  (i) if
there is no successor to the Corporation, the Corporation shall have the right
to exercise its Purchase Option as to all or any portion of the Stock then
subject to the Purchase Option set forth above to the same extent as if
Purchaser's employment by the Corporation had ceased on the date preceding the
date of consummation of said event or transaction or (ii) the Purchase Option
may be assigned to any successor of the Corporation, and the Purchase Option
shall apply if Purchaser shall cease for any reason to be an employee of such
successor on the same basis as set forth above.  In that case, references herein
to the "Corporation" shall be deemed to refer to such successor.

          (c)   The Corporation shall be entitled to pay for any shares
purchased pursuant to its Purchase Option at the Corporation's option in cash,
by offset against any indebtedness given in payment for the Stock, or a
combination of both.

                                       10
<PAGE>
 
          (d)   As used herein, employee, employment and similar terms shall
including acting as a consultant or director of the Corporation, and employment
with the Corporation shall include employment with an affiliate of the
Corporation.

          (e)   This Agreement is not an employment contract and nothing in this
Agreement shall be deemed to create in any way whatsoever any obligation on the
part of Purchaser to continue in the employ of the Corporation, or of the
Corporation to continue Purchaser in the employ of the Corporation.

          (f)   In the event that the Stock's fair market value (as defined in
the Plan) is equal to or exceeds the Option Price on the date that the
Purchaser ceases to be employed, the Company shall exercise its purchase
option to the extent permitted by law.

     3.   The Purchase Option may be exercised by giving written notice of
exercise delivered or mailed as provided in paragraph 14.  Upon providing of
such notice and payment or tender of the purchase price, the Corporation shall
become the legal and beneficial owner of the Stock being purchased and all
rights and interests therein or related thereto.

     4.   If from time to time during the term of the Purchase Option there is
any stock dividend or liquidating dividend or distribution of cash and/or
property, stock split or other change in the character or amount of any of the
outstanding securities of the Corporation, then, in such event, any and all new,
substituted or additional securities or other property to which Purchaser is
entitled by reason of his ownership of Stock will be immediately subject to the
Purchase Option and be included in the word "Stock" for all purposes of the
Purchase Option with the same force and effect as the shares of Stock then
subject to the Purchase Option.  While the total Option Price shall remain the
same after each such event, the Option Price per share of Stock upon exercise of
the Purchase Option shall be appropriately adjusted.

     5.   All certificates representing any shares of Stock of the Corporation
subject to the provisions of this Agreement shall have endorsed thereon legends
in substantially the following form:

                (i)   "The shares represented by this certificate are subject
to an option set forth in an agreement between the corporation and the
registered holder, or his predecessor in interest, a copy of which is on file
at the principal office of this corporation. Any transfer or attempted
transfer of any shares subject to such option is void without the prior
express written consent of the issuer of these shares."

                (ii)  "These securities have not been registered under the
Securities Act of 1933. They may not be sold, offered for sale, pledged or
hypothecated in the absence of an effective registration statement as to the
securities under said Act or an opinion of counsel satisfactory to the
corporation that such registration is not required."

               (iii)  Any legend required to be placed thereon by the California
Commissioner of Corporations.

     6.   Purchaser acknowledges that he is aware that the Stock to be issued to
him by the Corporation pursuant to this Agreement has not been registered under
the Securities Act of 1933, 

                                       11
<PAGE>
 
as amended (the "Act"), on the basis that no distribution or public offering
of the Stock is to be effected, and in this connection acknowledges that the
Corporation is relying on the following representations. In this connection,
Purchaser warrants and represents to the Corporation that he is acquiring the
Stock for investment and not with a view to or for sale in connection with any
distribution of the Stock or with any present intention of distributing or
selling the Stock and he does not presently have reason to anticipate any
change in circumstances or any particular occasion or event which would cause
him to sell the Stock. Purchaser recognizes that the Stock must be held
indefinitely unless it is subsequently registered under the Act or an
exemption from such registration is available and, further, recognizes that
the Corporation is under no obligation to register the Stock or to comply with
any exemption from such registration.

     7.   Purchaser is aware that the Stock may not be sold pursuant to Rule 144
adopted under the Act unless certain conditions are met and until Purchaser has
held the Stock for at least two (2) years.  Among the conditions for use of Rule
144 is the availability of specified current public information about the
Corporation.  Purchaser recognizes that the Corporation presently has no plans
to make such information available to the public.

     Whether or not the Purchase Option is exercised or has lapsed, Purchaser
further agrees not to make any disposition of any of the Stock in any event
unless and until:

          (a)   There is then in effect a registration statement under the Act
covering such proposed disposition and such disposition is made in accordance
with such registration statement; or

          (b)   (i)   Purchaser shall have notified the Corporation of the
proposed disposition and shall have furnished the Corporation with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii)
Purchaser shall have given the Corporation an opinion of counsel, which
opinion and counsel shall be satisfactory to the Corporation, to the effect
that such disposition will not require registration of the Stock under the
Act.

     8.   As security for his faithful performance of the terms of this
Agreement and to insure the availability for delivery of Purchaser's Stock
upon exercise of the Purchase Option herein provided for, Purchaser agrees, at
the closing hereunder (or as soon thereafter as practicable), to deliver (or
have the Corporation deliver on the Purchaser's behalf) to and deposit with
the Secretary of the Corporation ("Escrow Agent"), as Escrow Agent in this
transaction, three (3) stock assignments duly endorsed (with date and number
of shares left blank) in the form attached hereto as Exhibit B, together with
a certificate or certificates evidencing all of the Stock subject to the
Purchase Option; said documents are to be held by the Escrow Agent and
delivered by said Escrow Agent pursuant to the Joint Escrow Instructions of
the Corporation and Purchaser set forth in Exhibit C attached hereto and
incorporated herein by this reference, which instructions shall also be
delivered to the Escrow Agent at the closing hereunder (or as soon thereafter
as practicable). If a portion of the total purchase price is paid by a
promissory note, the Stock is also subject to the Pledge Agreement, and
possession of the certificates and stock assignments by the Escrow Agent shall
also constitute possession by the Corporation of such instruments pursuant to
the Pledge Agreement.

                                       12
<PAGE>
 
     9.   Purchaser shall not sell or transfer any of the Stock subject to the
Purchase Option or any interest therein so long as such Stock is subject to the
Purchase Option or the Pledge Agreement.

     10.  The Corporation shall not be required (i) to transfer on its books any
shares of Stock of the Corporation which shall have been sold or transferred in
violation of any of the provisions set forth in this Agreement or (ii) to treat
as owner of such shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such shares shall have been so transferred.

     11.  Subject to the provisions of paragraphs 9 and 10 above, Purchaser (but
not any unapproved transferee) shall, during the term of this Agreement,
exercise all rights and privileges of a stockholder of the Corporation with
respect to the Stock.

     12.  Purchaser acknowledges receipt of a copy of Section 260.141.11 of
Title 10 of the California Code of Regulations, attached hereto as Exhibit D.

     13.  The parties agree to execute such further instruments and to take such
further action as reasonably may be necessary to carry out the intent of this

Terayon Communication Systems, Inc.
2952 Bunker Hill Lane
Santa Clara, CA  95054
Attn:  Secretary

Dear Sir or Madam:

     As Escrow Agent for both Terayon Communication Systems, Inc., a Delaware
corporation ("Corporation"), and the undersigned purchaser of stock of the
Corporation ("Purchaser"), you are hereby authorized and directed to hold the
documents delivered to you pursuant to the terms of that certain Early Exercise
Stock Purchase Agreement ("Agreement"), dated ____________________, to which a
copy of these Joint Escrow Instructions is attached as Exhibit C, in accordance
with the following instructions:

     1.   In the event the Corporation or an assignee shall elect to exercise
the Purchase Option set forth in the Agreement, the Corporation or its assignee
will give to Purchaser and you a written notice specifying the number of shares
of stock to be purchased, the purchase price, and the time for a closing
hereunder at the principal office of the Corporation. Purchaser and the
Corporation hereby irrevocably authorize and direct you to close the transaction
contemplated by such notice in accordance with the terms of said notice.

     2.   At the closing you are directed (a) to date any stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Corporation against the
simultaneous delivery to you of the purchase price (which may include suitable
acknowledgment of cancellation of indebtedness) of the number of shares of stock
being purchased pursuant to the exercise of the Purchase Option.

     3.   Purchaser irrevocably authorizes the Corporation to deposit with you
any certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as specified in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as his attorney-in-
fact and agent for the term of this escrow to execute with respect to such
securities and other property all documents of assignment and/or transfer and
all stock certificates necessary or appropriate to make all securities
negotiable and complete any transaction herein contemplated.

     4.   This escrow shall terminate upon expiration or exercise in full of the
Purchase Option, whichever occurs first.

     5.   If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Purchaser,
you shall deliver all of same to Purchaser and shall be discharged of all
further obligations hereunder; provided, however, that if at the time of
termination of this escrow you are advised by the Corporation that the property

                                       17
<PAGE>
 
subject to this escrow is the subject of a pledge or other security agreement,
you shall deliver all such property to the pledgeholder or other person
designated by the Corporation.

     6.   Except at otherwise provided in these Joint Escrow Instructions, your
duties hereunder may be altered, amended, modified or revoked only by a writing
signed by all of the parties hereto.

     7.   You shall be obligated only for the performance of such duties as are
specifically set forth herein and may rely and shall be protected in relying or
refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties or
their assignees.  You shall not be personally liable for any act you may do or
omit to do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while
acting in good faith and any act done or omitted by you pursuant to the advice
of your own attorneys shall be conclusive evidence of such good faith.

     8.   You are hereby expressly authorized to disregard any and all warnings
given by any of the parties hereto or by any other person or corporation,
excepting only orders or process of courts of law, and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court.
In case you obey or comply with any such order, judgment or decree of any court,
you shall not be liable to any of the parties hereto or to any other person,
firm or corporation by reason of such compliance, notwithstanding any such
order, judgment or decree being subsequently reversed, modified, annulled, set
aside, vacated or found to have been entered without jurisdiction.

     9.   You shall not be liable in any respect on account of the identity,
authority or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

     10.  You shall not be liable for the outlawing of any rights under any
statute of limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

     11.  You shall be entitled to employ such legal counsel (including without
limitation the firm of Cooley Godward llp) and other experts as you may deem
necessary properly to advise you in connection with your obligations hereunder,
may rely upon the advice of such counsel, and may pay such counsel reasonable
compensation therefor.

     12.  Your responsibilities as Escrow Agent hereunder shall terminate if you
shall cease to be Secretary of the Corporation or if you shall resign by written
notice to each party.  In the event of any such termination, the Corporation may
appoint any officer or assistant officer of the Corporation as successor Escrow
Agent and Purchaser hereby confirms the appointment of such successor or
successors as his attorney-in-fact and agent to the full extent of your
appointment.

     13.  If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

     14.  It is understood and agreed that should any dispute arise with respect
to the delivery and/or ownership or right of possession of the securities, you
may (but are not obligated 

                                       18
<PAGE>
 
to) retain in your possession without liability to anyone all or any part of
said securities until such dispute shall have been settled either by mutual
written agreement of the parties concerned or by a final order, decree or
judgment of a court of competent jurisdiction after the time for appeal has
expired and no appeal has been perfected, but you shall be under no duty
whatsoever to institute or defend any such proceedings.

     15.  Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon personal delivery or upon deposit in
any United States Post Box, by registered or certified mail with postage and
fees prepaid, addressed to each of the other parties hereunto entitled at the
following addresses, or at such other addresses as a party may designate by ten

                             STOCK PLEDGE AGREEMENT

     1.   As collateral security for the payment of that certain promissory note
in principal amount of $______________ issued this date to _____________________
("Pledgee") by the undersigned (hereinafter called "indebtedness"), the
undersigned hereby assigns, transfers to and pledges with the Pledgee the
securities listed on Schedule 1 hereto which were this day delivered to be
deposited with Pledgee, together with any stock rights, rights to subscribe,
dividends paid in cash or other property in connection with the complete or
partial liquidation of Pledgee, stock dividends, dividends paid in stock, new
securities or other property except cash dividends other than liquidating
dividends to which the undersigned is or may hereafter become entitled to
receive on account of such property, and in the event that the undersigned
receives any such, the undersigned will immediately deliver it to Pledgee to be
held by Pledgee hereunder in the same manner as the property originally pledged
hereunder.  All property assigned, transferred to and pledged with Pledgee under
this paragraph is hereinafter called "collateral."

     2.   At any time, without notice, and at the expense of the undersigned,
Pledgee in its name or in the name of its nominee or of the undersigned may, but
shall not be obligated to:  (1) collect by legal proceedings or otherwise all
dividends (except cash dividends other than liquidating dividends), interest,
principal payments and other sums now or hereafter payable upon or on account of
said collateral; (2) enter into any extension, reorganization, deposit, merger,
or consolidation agreement, or any agreement in any wise relating to or
affecting the collateral, and in connection therewith may deposit or surrender
control of such collateral thereunder, accept other property in exchange for
such collateral and do and perform such acts and things as it may deem proper,
and any money or property received in exchange for such collateral shall be
applied to the indebtedness or thereafter held by it pursuant to the provisions
hereof; (3) insure, process and preserve the collateral; (4) cause the
collateral to be transferred to its name or to the name of its nominee; (5)
exercise as to such collateral all the rights, powers, and remedies of an owner,
except that so long as the indebtedness is not in default the undersigned shall
retain all voting rights as to the collateral.

     3.   The undersigned agrees to pay prior to delinquency all taxes, charges,
liens and assessments against the collateral, and upon the failure of the
undersigned to do so Pledgee at its option may pay any of them and shall be the
sole judge of the legality or validity thereof and the amount necessary to
discharge the same.

     4.   All advances, charges, costs and expenses, including reasonable
attorneys' fees, incurred or paid by Pledgee in exercising any right, power or
remedy conferred by this agreement, or in the enforcement thereof, shall become
a part of the indebtedness secured hereunder and shall be paid to Pledgee by the
undersigned immediately and without demand.

     5.   At the option of Pledgee and without necessity of demand or notice,
all or any part of the indebtedness of the undersigned shall immediately become
due and payable irrespective of any agreed maturity, upon the happening of any
of the following events: (1) failure to keep or perform any of the terms or
provisions of this agreement; (2) default in the payment of principal or
interest when due; (3) the levy of any attachment, execution or other

                                       24
<PAGE>
 
process against the collateral; or (4) the insolvency, commission of an act of
bankruptcy, general assignment for the benefit of creditors, filing of any
petition in bankruptcy or for relief under the provisions of Title 11, United
States Code, Bankruptcy, of, by, or against the undersigned.

     6.   In the event of the nonpayment of any indebtedness when due, whether
by acceleration or otherwise, or upon the happening of any of the events
specified in the last preceding paragraph, Pledgee may then, or at any time
thereafter, at its election, apply, set off, collect or sell in one or more
sales, or take such steps as may be necessary to liquidate and reduce to cash in
the hands of Pledgee in whole or in part, with or without any previous demands
or demand of performance or notice or advertisement, the whole or any part of
the collateral in such order as Pledgee may elect, and any such sale may be made
either at public or private sale at its place of business or elsewhere, or at
any broker's board or securities exchange, either for cash or upon credit or for
future delivery; provided, however, that if such disposition is at private sale,
then the purchase price of the collateral shall be equal to the public market
price then in effect, or, if at the time of sale no public market for the
collateral exists, then, in recognition of the fact that the sale of the
collateral would have to be registered under the Securities Act of 1933 and that
the expenses of such registration are commercially unreasonable for the type and
amount of collateral pledged hereunder, Pledgee and the undersigned hereby agree
that such private sale shall be at a purchase price mutually agreed to by
Pledgee and the undersigned or, if the parties cannot agree upon a purchase
price, then at a purchase price established by a majority of three independent
appraisers knowledgeable of the value of such collateral, one named by the
undersigned within 10 days after written request by the Pledgee to do so, one
named by Pledgee within such 10 day period, and the third named by the two
appraisers so selected, with the appraisal to be rendered by such body within 30
days of the appointment of the third appraiser. The cost of such appraisal,
including all appraiser's fees, shall be charged against the proceeds of sale as
an expense of such sale. Pledgee may be the purchaser of any or all collateral
so sold and hold the same thereafter in its own right free from any claim of the
undersigned or right of redemption. Demands of performance, notices of sale,
advertisements and presence of property at sale are hereby waived, and Pledgee
is hereby authorized to sell hereunder any evidence of debt pledged to it. Any
sale hereunder may be conducted by any officer or agent of Pledgee.

     7.   The proceeds of the sale of any of the collateral and all sums
received or collected by Pledgee from or on account of such collateral shall be
applied by Pledgee to the payment of expenses incurred or paid by Pledgee in
connection with any sale, transfer or delivery of the collateral, to the payment
of any other costs, charges, attorneys' fees or expenses mentioned herein, and
to the payment of the indebtedness or any part hereof, all in such order and
manner as Pledgee in its discretion may determine. Pledgee shall pay any balance
to the undersigned.

     8.   Pledgee shall be under no duty or obligation whatsoever to make or
give any presentments, demands for performance, notices of non-performance,
protests, notices of protest or notices of dishonor in connection with any
obligations or evidences of indebtedness held by Pledgee as collateral, or in
connection with any obligations or evidences of indebtedness which constitute in
whole or in part the indebtedness secured hereunder.

     9.   Pledgee may at any time deliver the collateral or any part thereof to
the undersigned and the receipt of the undersigned shall be a complete and full
acquittance for the 

                                       25
<PAGE>
 
collateral so delivered, and Pledgee shall thereafter be discharged from any
liability or responsibility therefor.

     10.  Upon the transfer of all or any part of the indebtedness Pledgee may
transfer all or any part of the collateral and shall be fully discharged
thereafter from all liability and responsibility with respect to such collateral
so transferred, and the transferee shall be vested with all the rights and
powers of Pledgee hereunder with respect to such collateral so transferred; but
with respect to any collateral not so transferred Pledgee shall retain all
rights and powers hereby given.

     11.  Until all indebtedness shall have been paid in full the power of sale
and all other rights, powers and remedies granted to Pledgee hereunder shall
continue to exist and may be exercised by Pledgee at any time and from time to
time irrespective of the fact that the indebtedness or any part thereof may have
become barred by any statute of limitations, or that the personal liability of
the undersigned may have ceased.

     12.  Pledgee agrees that so long as the indebtedness is not in default,
shares of Terayon Communication Systems, Inc. common stock held hereunder as
collateral for the indebtedness shall be released from pledge as the
indebtedness is paid.  Such releases shall be at the rate of one share for each
$____________ of principal amount of indebtedness paid.  Release from pledge,
however, shall not result in release from the provisions of those certain Joint
Escrow Instructions, if any, of even date herewith among the parties to this
Pledge Agreement and the Escrow Agent named therein or from the Purchase Option
of Terayon Communication Systems, Inc., set forth in the Early Exercise Stock
Purchase Agreement dated __________________, 19__, if any, between the parties
to this Pledge Agreement.

     13.  The rights, powers and remedies given to Pledgee by this agreement
shall be in addition to all rights, powers and remedies given to Pledgee by
virtue of any statute or rule of law.  Pledgee may exercise its Pledgee's lien
or right of setoff with respect to the indebtedness in the same manner as if the
indebtedness were unsecured.  Any forbearance or failure or delay by Pledgee in
exercising any right, power or remedy hereunder shall not be deemed to be a
waiver of such right, power or remedy, and any single or partial exercise of any
right, power or remedy hereunder shall not preclude the further exercise
thereof; and every right, power and remedy of

                                       26

Pledgee shall continue in full force and effect until such right, power or
remedy is specifically waived by an instrument in writing executed by Pledgee.

                            STOCK OPTION AGREEMENT

     Pursuant to the Grant Notice and this Stock Option Agreement, the Company
has granted you an option to purchase the number of shares of the Company's
common stock ("Common Stock") indicated in the Grant Notice at the exercise
price indicated in the Grant Notice.

     Your option is granted in connection with and in furtherance of the
Company's compensatory benefit plan for the Company's employees (including
officers), directors or consultants.  Defined terms not explicitly defined in
this Stock Option Agreement but defined in the Plan shall have the same
definitions as in the Plan.

     The details of your option are as follows:

     1.   VESTING.  Subject to the limitations contained herein, your option
will vest as provided in the Grant Notice, provided that vesting will cease upon
the termination of your Continuous Status as an Employee, Director or
Consultant.

     2.   METHOD OF PAYMENT.

          (a)   PAYMENT OPTIONS.  Payment of the exercise price by cash or check
is due in full upon exercise of all or any part of your option, provided that
you may elect, to the extent permitted by applicable law and the Grant Notice,
to make payment of the exercise price under one of the following alternatives:

                (i)   Payment pursuant to a program developed under Regulation T
as promulgated by the Federal Reserve Board which, prior to the issuance of
Common Stock, results in either the receipt of cash (or check) by the Company or
the receipt of irrevocable instructions to pay the aggregate exercise price to
the Company from the sales proceeds;

                (ii)  Provided that at the time of exercise the Company's Common
Stock is publicly traded and quoted regularly in the Wall Street Journal,
payment by delivery of already-owned shares of Common Stock, held for the period
required to avoid a charge to the Company's reported earnings, and owned free
and clear of any liens, claims, encumbrances or security interests, which Common
Stock shall be valued at its fair market value on the date of exercise; or

                (iii) Payment by a combination of the above methods.

     3.   WHOLE SHARES.  Your option may only be exercised for whole shares.

     4.   SECURITIES LAW COMPLIANCE.  Notwithstanding anything to the contrary
contained herein, your option may not be exercised unless the shares issuable
upon exercise of your option are then registered under the Securities Act or, if
such shares are not then so registered, the Company has determined that such
exercise and issuance would be exempt from the registration requirements of the
Securities Act.

     5.   TERM.  The term of your option commences on the Date of Grant and
expires upon the earliest of:

          (i)   the Expiration Date indicated in the Grant Notice;

          (ii)  the tenth (10th) anniversary of the Date of Grant;

                                       2
<PAGE>
 
          (iii) eighteen (18) months after your death, if you die during, or
within three (3) months after the termination of your Continuous Status as an
Employee, Director or Consultant;

          (iv)  twelve (12) months after the termination of your Continuous
Status as an Employee, Director or Consultant due to disability;

          (v)   immediately after the termination of your Continuous Status as
Employee, Director or Consultant for Cause; or

          (vi)  three (3) months after the termination of your Continuous Status
as an Employee, Director or Consultant for any other reason, provided that if
during any part of such three (3)-month period the option is not exercisable
solely because of the condition set forth in paragraph 5 (Securities Law
Compliance), in which event the option shall not expire until the earlier of the
Expiration Date or until it shall have been exercisable for an aggregate period
of three (3) months after the termination of Continuous Status as an Employee,
Director or Consultant.

          For these purposes, "Cause" shall include, but not be limited to, the
commission of any act of fraud, embezzlement or dishonesty, any unauthorized use
or disclosure of confidential information or trade secrets of the Company, or
any other intentional misconduct adversely affecting the business or affairs of
the Company in a material manner.  The foregoing definition shall not be deemed
to be inclusive of all the acts or omissions which the Company may consider as
grounds for your dismissal or discharge.

          To obtain the federal income tax advantages associated with an
"incentive stock option," the Code requires that at all times beginning on the
grant date of the option and ending on the day three (3) months before the date
of the option's exercise, you must be an employee of the Company, except in the
event of your death or permanent and total disability.  The Company cannot
guarantee that your option will be treated as an "incentive stock option" if you
exercise your option more than three (3) months after the date your employment
with the Company terminates.  Termination of employment, for ISO purposes,
includes cessation of employment, but continued service as a director or
consultant (notwithstanding that your continuous status will not have terminated
for purpose of this Stock Option Agreement or the Plan).

     6.   EXERCISE.

          (a)   You may exercise the vested portion of your option during its
term (and the unvested portion of your option if the Grant Notice so permits) by
delivering a notice of exercise (in a form designated by the Company) together
with the exercise price to the Secretary of the Company, or to such other person
as the Company may designate, during regular business hours, together with such
additional documents as the Company may then require.

          (b)   By exercising your option you agree that:

                (i)   as a condition to any exercise of your option, the Company
may require you to enter an arrangement providing for the payment by you to the
Company of any tax withholding obligation of the Company arising by reason of
(1) the exercise of your option; (2) the lapse of any substantial risk of
forfeiture to which the shares are subject at the time of exercise; or (3) the
disposition of shares acquired upon such exercise;

                (ii)  you will notify the Company in writing within fifteen (15)
days after the date of any disposition of any of the shares of the Common Stock
issued upon exercise of an incentive stock option that occurs within two (2)
years after the Date of Grant or within one (1) year after such shares of Common
Stock are transferred upon exercise of your option; and

                                       3
<PAGE>
 
                (iii) the Company (or a representative of the underwriters) may,
in connection with the first underwritten registration of the offering of any
securities of the Company under the Act, require that you not sell or otherwise
transfer or dispose of any shares of Common Stock or other securities of the
Company during such period (not to exceed one hundred eighty (180) days)
following the effective date of the registration statement of the Company filed
under the Act as may be requested by the Company or the representative of the
underwriters. You further agree that the Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such period.

     7.   TRANSFERABILITY.  Your option is not transferable, except by will or
by the laws of descent and distribution, and is exercisable during your life
only by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party
who, in the event of your death, shall thereafter be entitled to exercise your
option.

     8.   RIGHT OF FIRST REFUSAL/RIGHT OF REPURCHASE.  Vested shares that are
received upon exercise of your option are subject to any right of first refusal
that may be described in the Company's bylaws in effect at such time the Company
elects to exercise its right.  The Company's right of first refusal shall expire
on the date of the first registration of an equity security of the Company under
Section 12 of the Exchange Act.  In addition, to the extent provided in the
Company's bylaws as amended from time to time, the Company shall have the right
to repurchase all or any part of the shares received pursuant to the exercise of
your option, which right shall be in addition to any right created by exercise
prior to vesting.

     9.   OPTION NOT A SERVICE CONTRACT.  Your option is not an employment
contract and nothing in your option shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company,
or of the Company to continue your employment with the Company.  In addition,
nothing in your option shall obligate the Company, its shareholders, board of
directors, officers or employees to continue any relationship which you might
have as a director or consultant for the Company.

     10.  NOTICES.  Any notices provided for in your option or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by the Company to you, five (5) days after deposit in
the United States mail, postage prepaid, addressed to you at the last address
you provided to the Company.

     11.  GOVERNING PLAN DOCUMENT.  Your option is subject to all the provisions
of the Plan, the provisions of which are hereby made a part of your option,
including without limitation the provisions of the Plan relating to option
provisions, and is further subject to all interpretations, amendments, rules and
regulations which may from time to time be promulgated and adopted pursuant to
the Plan.  In the event of any conflict between the provisions of your option
and those of the Plan, the provisions of the Plan shall control.

                   EARLY EXERCISE STOCK PURCHASE AGREEMENT

     THIS AGREEMENT is made by and between TERAYON COMMUNICATION SYSTEMS, INC.,
a Delaware corporation (the "Corporation"), and ________________ ("Purchaser").

                                 WITNESSETH:

     WHEREAS, Purchaser holds an incentive/nonstatutory stock option to purchase
shares of common stock of the Corporation pursuant to the Corporation's 1997
Equity Incentive Plan (the "Plan") which Purchaser desires to exercise; and

     WHEREAS, Purchaser wishes to take advantage of the early exercise provision
of his option and therefore to enter into this Agreement;

     NOW, THEREFORE, IT IS AGREED between the parties as follows:

     1.   Purchaser hereby agrees to purchase from the Corporation, and the
Corporation hereby agrees to sell to Purchaser, an aggregate of

to be paid by promissory note) and an executed pledge agreement in the form of
Exhibit F (the "Pledge Agreement") under which all shares of the Stock
acquired by Note shall be pledged as collateral security for the payment of
the indebtedness represented by the Note; and including endorsed certificates
representing the appropriate number of shares of the Corporation's common
stock if a portion of the total exercise price is to be paid by common stock.

     At the closing or as soon thereafter as practicable, the Corporation shall
deliver to the Escrow Agent (as defined in paragraph 8 below) share certificates
for all of the Stock that is to be subject to the Purchase Option (as defined in
paragraph 2 below), and shall deliver share certificates to Purchaser for all of
the Stock, if any, that is not to be subject to the Purchase Option or the
Pledge Agreement.  The certificates for all of the Stock that is subject to the
Pledge Agreement but not the Purchase Option shall be retained by the
Corporation as security pursuant to the Pledge Agreement.

     2.   In accordance with the provisions of section 408(b) of the California
General Corporation Law, the Stock to be purchased by Purchaser pursuant to this
Agreement shall be subject to the following option ("Purchase Option"):

          (a)   In the event that Purchaser shall cease to have a service
relationship with the Corporation for any reason (including his death), or no
reason, with or without cause, the Purchase Option may be exercised.  The
Corporation shall have the right at any time within sixty (60) days after such
cessation of employment to purchase from Purchaser or his personal
representative, as the case may be, at the price per share paid by Purchaser
pursuant to this Agreement ("Option Price"), up to but not exceeding the number
of shares of the Stock set forth on Exhibit A hereto which is incorporated
herein by this reference.

          (b)   In addition, and without limiting the foregoing Purchase Option,
if at any time during the term of the Purchase Option, there occurs:  (a) a
dissolution or liquidation of the Corporation; (b) a merger or consolidation
involving the Corporation in which the Corporation is not the surviving
corporation; (c) a reverse merger in which the Corporation is the surviving
corporation but the shares of the Corporation's common stock outstanding
immediately preceding the merger are converted by virtue of the merger into
other property, whether in the form of other securities, cash or otherwise; or
(d) any other capital reorganization in which more than fifty percent (50%) of
the shares of the Corporation entitled to vote are exchanged, then:  (i) if
there is no successor to the Corporation, the Corporation shall have the right
to exercise its Purchase Option as to all or any portion of the Stock then
subject to the Purchase Option set forth above to the same extent as if
Purchaser's service relationship with the Corporation had ceased on the date
preceding the date of consummation of said event or transaction or (ii) the
Purchase Option may be assigned to any successor of the Corporation, and the
Purchase Option shall apply if Purchaser shall cease for any reason to have a
service relationship with such successor on the same basis as set forth above.
In that case, references herein to the "Corporation" shall be deemed to refer to
such successor.

          (c)   The Corporation shall be entitled to pay for any shares
purchased pursuant to its Purchase Option at the Corporation's option in cash,
by offset against any indebtedness given in payment for the Stock, or a
combination of both.

                                       8
<PAGE>
 
          (d)   As used herein, service relationship and similar terms shall
include acting as a consultant or director of the Corporation.

          (e)   This Agreement is not a service contract and nothing in this
Agreement shall be deemed to create in any way whatsoever any obligation on the
part of Purchaser to continue in the service of the Corporation, or of the
Corporation to continue Purchaser in the service of the Corporation.

          (f)   In the event that the Stock's fair market value (as defined in
the Plan) is equal to or exceeds the Option Price on the date that the
Purchaser ceases to have a service relationship with the Corporation, the
Company shall exercise its purchase option to the extent permitted by law.

     3.   The Purchase Option may be exercised by giving written notice of
exercise delivered or mailed as provided in paragraph 14.  Upon providing of
such notice and payment or tender of the purchase price, the Corporation shall
become the legal and beneficial owner of the Stock being purchased and all
rights and interests therein or related thereto.

     4.   If from time to time during the term of the Purchase Option there is
any stock dividend or liquidating dividend or distribution of cash and/or
property, stock split or other change in the character or amount of any of the
outstanding securities of the Corporation, then, in such event, any and all new,
substituted or additional securities or other property to which Purchaser is
entitled by reason of his ownership of Stock will be immediately subject to the
Purchase Option and be included in the word "Stock" for all purposes of the
Purchase Option with the same force and effect as the shares of Stock then
subject to the Purchase Option.  While the total Option Price shall remain the
same after each such event, the Option Price per share of Stock upon exercise of
the Purchase Option shall be appropriately adjusted.

     5.   All certificates representing any shares of Stock of the Corporation
subject to the provisions of this Agreement shall have endorsed thereon legends
in substantially the following form:

                (i)   "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
AN OPTION SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED
HOLDER, OR HIS PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE
PRINCIPAL OFFICE OF THIS CORPORATION. ANY TRANSFER OR ATTEMPTED TRANSFER OF
ANY SHARES SUBJECT TO SUCH OPTION IS VOID WITHOUT THE PRIOR EXPRESS WRITTEN
CONSENT OF THE ISSUER OF THESE SHARES."

                (ii)  "THESE SECURITIES HAVE NOT BEEN REGISTERED  UNDER THE 
SECURITIES ACT OF 1933. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE
SECURITIES UNDER SAID ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE
CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED."

                (iii) "ANY LEGEND REQUIRED TO BE PLACED THEREON BY THE
CALIFORNIA COMMISSIONER OF CORPORATIONS.

     6.   Purchaser acknowledges that he is aware that the Stock to be issued
to him by the Corporation pursuant to this Agreement has not been registered
under the Securities Act of 1933, as amended (the "Act"), on the basis that no
distribution or public offering of the Stock is to be effected, and in this
connection acknowledges that the Corporation is relying on the following
representations. In this connection, Purchaser warrants and represents to the
Corporation that he is acquiring the Stock for investment and not with a view
to or for sale in connection with any distribution of the Stock or with any
present intention of distributing or selling the Stock and he does not
presently have reason to anticipate any change in circumstances or any
particular occasion or event which would cause him to sell the Stock.
Purchaser recognizes that the Stock must be held indefinitely unless it is
subsequently registered under the Act or an exemption from such registration
is available and, further, recognizes that the Corporation is under no
obligation to register the Stock or to comply with any exemption from such
registration.

     7.   Purchaser is aware that the Stock may not be sold pursuant to Rule 144
adopted under the Act unless certain conditions are met and until Purchaser has
held the Stock for at least two (2) years.  Among the conditions for use of Rule
144 is the availability of specified current public information about the
Corporation.  Purchaser recognizes that the Corporation presently has no plans
to make such information available to the public.

     Whether or not the Purchase Option is exercised or has lapsed, Purchaser
further agrees not to make any disposition of any of the Stock in any event
unless and until:

          (a)   There is then in effect a registration statement under the Act
covering such proposed disposition and such disposition is made in accordance
with such registration statement; or

          (b)   (i)   Purchaser shall have notified the Corporation of the
proposed disposition and shall have furnished the Corporation with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii)
Purchaser shall have given the Corporation an opinion of counsel, which
opinion and counsel shall be satisfactory to the Corporation, to the effect
that such disposition will not require registration of the Stock under the
Act.

     8.   As security for his faithful performance of the terms of this
Agreement and to insure the availability for delivery of Purchaser's Stock
upon exercise of the Purchase Option herein provided for, Purchaser agrees, at
the closing hereunder (or as soon thereafter as practicable), to deliver (or
have the Corporation deliver on the Purchaser's behalf) to and deposit with
the Secretary of the Corporation ("Escrow Agent"), as Escrow Agent in this
transaction, three (3) stock assignments duly endorsed (with date and number
of shares left blank) in the form attached hereto as Exhibit B, together with
a certificate or certificates evidencing all of the Stock subject to the
Purchase Option; said documents are to be held by the Escrow Agent and
delivered by said Escrow Agent pursuant to the Joint Escrow Instructions of
the Corporation and Purchaser set forth in Exhibit C attached hereto and
incorporated herein by this reference, which instructions shall also be
delivered to the Escrow Agent at the closing hereunder (or as soon 

                                       10
<PAGE>
 
thereafter as practicable). If a portion of the total purchase price is paid
by a promissory note, the Stock is also subject to the Pledge Agreement, and
possession of the certificates and stock assignments by the Escrow Agent shall
also constitute possession by the Corporation of such instruments pursuant to
the Pledge Agreement. 

     9.   Purchaser shall not sell or transfer any of the Stock subject to the
Purchase Option or any interest therein so long as such Stock is subject to the
Purchase Option or the Pledge Agreement.

     10.  The Corporation shall not be required (i) to transfer on its books any
shares of Stock of the Corporation which shall have been sold or transferred in
violation of any of the provisions set forth in this Agreement or (ii) to treat
as owner of such shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such shares shall have been so transferred.

     11.  Subject to the provisions of paragraphs 9 and 10 above, Purchaser (but
not any unapproved transferee) shall, during the term of this Agreement,
exercise all rights and privileges of a stockholder of the Corporation with
respect to the Stock.

     12.  Purchaser acknowledges receipt of a copy of Section 260.141.11 of
Title 10 of the California Code of Regulations, attached hereto as Exhibit D.

     13.  The parties agree to execute such further instruments and to take such
further action as reasonably may be necessary to carry out the intent of this
Agreement.

     14.  Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon personal delivery or upon deposit in
any United States Post Office Box, by registered or certified mail with postage
and fees prepaid, addressed to the other party hereto at his address hereinafter
shown below his signature or at such other address as such party may designate
by ten (10) days' advance written notice to the other party hereto.

     15.  This Agreement shall bind and inure to the benefit of the successors
and assigns of the Corporation and, subject to the restrictions on transfer
herein set forth, inure to the benefit of and be binding upon Purchaser, his
heirs, executors, administrators, successors, and assigns.  Without limiting the
generality of the foregoing, the Purchase Option of the Corporation hereunder
shall be assignable by the Corporation at any time or from time to time, in
whole or in part.  Should the right of repurchase be assigned by the
Corporation, the assignee shall pay to the 

                                       11
<PAGE>
 
Corporation cash equal to the excess, if any, of the Stock's Fair Market Value
(as defined in the Plan) over the Option Price.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the ____ of _________, 199_.

Terayon Communication Systems, Inc.
2952 Bunker Hill Lane
Santa Clara, CA  95054
Attn:  Secretary

Dear Sir or Madam:

     As Escrow Agent for both Terayon Communication Systems, Inc., a Delaware
corporation ("Corporation"), and the undersigned purchaser of stock of the
Corporation ("Purchaser"), you are hereby authorized and directed to hold the
documents delivered to you pursuant to the terms of that certain Early Exercise
Stock Purchase Agreement ("Agreement"), dated ____________________, 199__, to
which a copy of these Joint Escrow Instructions is attached as Exhibit C, in
accordance with the following instructions:

     1.   In the event the Corporation or an assignee shall elect to exercise
the Purchase Option set forth in the Agreement, the Corporation or its
assignee will give to Purchaser and you a written notice specifying the number
of shares of stock to be purchased, the purchase price, and the time for a
closing hereunder at the principal office of the Corporation. Purchaser and
the Corporation hereby irrevocably authorize and direct you to close the
transaction contemplated by such notice in accordance with the terms of said
notice.

     2.   At the closing you are directed (a) to date any stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Corporation against the
simultaneous delivery to you of the purchase price (which may include suitable
acknowledgment of cancellation of indebtedness) of the number of shares of stock
being purchased pursuant to the exercise of the Purchase Option.

     3.   Purchaser irrevocably authorizes the Corporation to deposit with you
any certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as specified in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as his attorney-in-
fact and agent for the term of this escrow to execute with respect to such
securities and other property all documents of assignment and/or transfer and
all stock certificates necessary or appropriate to make all securities
negotiable and complete any transaction herein contemplated.

     4.   This escrow shall terminate upon expiration or exercise in full of the
Purchase Option, whichever occurs first.

     5.   If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Purchaser,
you shall deliver all of same to Purchaser and shall be discharged of all
further obligations hereunder; provided, however, that 

                                       16
<PAGE>
 
if at the time of termination of this escrow you are advised by the
Corporation that the property subject to this escrow is the subject of a
pledge or other security agreement, you shall deliver all such property to the
pledgeholder or other person designated by the Corporation.

     6.   Except at otherwise provided in these Joint Escrow Instructions, your
duties hereunder may be altered, amended, modified or revoked only by a writing
signed by all of the parties hereto.

     7.   You shall be obligated only for the performance of such duties as are
specifically set forth herein and may rely and shall be protected in relying or
refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties or
their assignees.  You shall not be personally liable for any act you may do or
omit to do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while
acting in good faith and any act done or omitted by you pursuant to the advice
of your own attorneys shall be conclusive evidence of such good faith.

     8.   You are hereby expressly authorized to disregard any and all warnings
given by any of the parties hereto or by any other person or corporation,
excepting only orders or process of courts of law, and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court.
In case you obey or comply with any such order, judgment or decree of any court,
you shall not be liable to any of the parties hereto or to any other person,
firm or corporation by reason of such compliance, notwithstanding any such
order, judgment or decree being subsequently reversed, modified, annulled, set
aside, vacated or found to have been entered without jurisdiction.

     9.   You shall not be liable in any respect on account of the identity,
authority or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

     10.  You shall not be liable for the outlawing of any rights under any
statute of limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

     11.  You shall be entitled to employ such legal counsel (including without
limitation the firm of Cooley Godward llp) and other experts as you may deem
necessary properly to advise you in connection with your obligations hereunder,
may rely upon the advice of such counsel, and may pay such counsel reasonable
compensation therefor.

     12.  Your responsibilities as Escrow Agent hereunder shall terminate if you
shall cease to be Secretary of the Corporation or if you shall resign by written
notice to each party.  In the event of any such termination, the Corporation may
appoint any officer or assistant officer of the Corporation as successor Escrow
Agent and Purchaser hereby confirms the appointment of such successor or
successors as his attorney-in-fact and agent to the full extent of your
appointment.

     13.  If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

respect to the delivery and/or ownership or right of possession of the
securities, you may (but are not obligated to) retain in your possession
without liability to anyone all or any part of said securities until such
dispute shall have been settled either by mutual written agreement of the
parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or
defend any such proceedings.

     15.  Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon personal delivery or upon deposit in

when due, the Company, at its sole option, shall have the right to accelerate
this Note, in which event the entire principal balance and all accrued interest
shall become immediately due and payable, and immediately collectible by the
Company pursuant to applicable law.

     This Note may be prepaid at any time without penalty.  All money paid

                           STOCK PLEDGE AGREEMENT

     1.   As collateral security for the payment of that certain promissory note
in principal amount of $______________ issued this date to _____________________
("Pledgee") by the undersigned (hereinafter called "indebtedness"), the
undersigned hereby assigns, transfers to and pledges with the Pledgee the
securities listed on Schedule 1 hereto which were this day delivered to be
deposited with Pledgee, together with any stock rights, rights to subscribe,
dividends paid in cash or other property in connection with the complete or
partial liquidation of Pledgee, stock dividends, dividends paid in stock, new
securities or other property except cash dividends other than liquidating
dividends to which the undersigned is or may hereafter become entitled to
receive on account of such property, and in the event that the undersigned
receives any such, the undersigned will immediately deliver it to Pledgee to be
held by Pledgee hereunder in the same manner as the property originally pledged
hereunder.  All property assigned, transferred to and pledged with Pledgee under
this paragraph is hereinafter called "collateral."

     2.   At any time, without notice, and at the expense of the undersigned,
Pledgee in its name or in the name of its nominee or of the undersigned may, but
shall not be obligated to:  (1) collect by legal proceedings or otherwise all
dividends (except cash dividends other than liquidating dividends), interest,
principal payments and other sums now or hereafter payable upon or on account of
said collateral; (2) enter into any extension, reorganization, deposit, merger,
or consolidation agreement, or any agreement in any wise relating to or
affecting the collateral, and in connection therewith may deposit or surrender
control of such collateral thereunder, accept other property in exchange for
such collateral and do and perform such acts and things as it may deem proper,
and any money or property received in exchange for such collateral shall be
applied to the indebtedness or thereafter held by it pursuant to the provisions
hereof; (3) insure, process and preserve the collateral; (4) cause the
collateral to be transferred to its name or to the name of its nominee; (5)
exercise as to such collateral all the rights, powers, and remedies of an owner,
except that so long as the indebtedness is not in default the undersigned shall
retain all voting rights as to the collateral.

     3.   The undersigned agrees to pay prior to delinquency all taxes, charges,
liens and assessments against the collateral, and upon the failure of the
undersigned to do so Pledgee at its option may pay any of them and shall be the
sole judge of the legality or validity thereof and the amount necessary to
discharge the same.

     4.   All advances, charges, costs and expenses, including reasonable
attorneys' fees, incurred or paid by Pledgee in exercising any right, power or
remedy conferred by this agreement, or in the enforcement thereof, shall become
a part of the indebtedness secured hereunder and shall be paid to Pledgee by the
undersigned immediately and without demand.

     5.   At the option of Pledgee and without necessity of demand or notice,
all or any part of the indebtedness of the undersigned shall immediately
become due and payable irrespective of any agreed maturity, upon the happening
of any of the following events: (1) failure to keep or perform any of the
terms or provisions of this agreement; (2) default in the 

                                       24
<PAGE>
 
payment of principal or interest when due; (3) the levy of any attachment,
execution or other process against the collateral; or (4) the insolvency,
commission of an act of bankruptcy, general assignment for the benefit of
creditors, filing of any petition in bankruptcy or for relief under the
provisions of Title 11, United States Code, Bankruptcy, of, by, or against the
undersigned.

     6.   In the event of the nonpayment of any indebtedness when due, whether
by acceleration or otherwise, or upon the happening of any of the events
specified in the last preceding paragraph, Pledgee may then, or at any time
thereafter, at its election, apply, set off, collect or sell in one or more
sales, or take such steps as may be necessary to liquidate and reduce to cash
in the hands of Pledgee in whole or in part, with or without any previous
demands or demand of performance or notice or advertisement, the whole or any
part of the collateral in such order as Pledgee may elect, and any such sale
may be made either at public or private sale at its place of business or
elsewhere, or at any broker's board or securities exchange, either for cash or
upon credit or for future delivery; provided, however, that if such
disposition is at private sale, then the purchase price of the collateral
shall be equal to the public market price then in effect, or, if at the time
of sale no public market for the collateral exists, then, in recognition of
the fact that the sale of the collateral would have to be registered under the
Securities Act of 1933 and that the expenses of such registration are
commercially unreasonable for the type and amount of collateral pledged
hereunder, Pledgee and the undersigned hereby agree that such private sale
shall be at a purchase price mutually agreed to by Pledgee and the undersigned
or, if the parties cannot agree upon a purchase price, then at a purchase
price established by a majority of three independent appraisers knowledgeable
of the value of such collateral, one named by the undersigned within 10 days
after written request by the Pledgee to do so, one named by Pledgee within
such 10 day period, and the third named by the two appraisers so selected,
with the appraisal to be rendered by such body within 30 days of the
appointment of the third appraiser. The cost of such appraisal, including all
appraiser's fees, shall be charged against the proceeds of sale as an expense
of such sale. Pledgee may be the purchaser of any or all collateral so sold
and hold the same thereafter in its own right free from any claim of the
undersigned or right of redemption. Demands of performance, notices of sale,
advertisements and presence of property at sale are hereby waived, and Pledgee
is hereby authorized to sell hereunder any evidence of debt pledged to it. Any
sale hereunder may be conducted by any officer or agent of Pledgee.

     7.   The proceeds of the sale of any of the collateral and all sums
received or collected by Pledgee from or on account of such collateral shall
be applied by Pledgee to the payment of expenses incurred or paid by Pledgee
in connection with any sale, transfer or delivery of the collateral, to the
payment of any other costs, charges, attorneys' fees or expenses mentioned
herein, and to the payment of the indebtedness or any part hereof, all in such
order and manner as Pledgee in its discretion may determine. Pledgee shall pay
any balance to the undersigned.

     8.   Pledgee shall be under no duty or obligation whatsoever to make or
give any presentments, demands for performance, notices of non-performance,
protests, notices of protest or notices of dishonor in connection with any
obligations or evidences of indebtedness held by Pledgee as collateral, or in
connection with any obligations or evidences of indebtedness which constitute
in whole or in part the indebtedness secured hereunder.

                                       25
<PAGE>
 
     9.   Pledgee may at any time deliver the collateral or any part thereof to
the undersigned and the receipt of the undersigned shall be a complete and full
acquittance for the collateral so delivered, and Pledgee shall thereafter be
discharged from any liability or responsibility therefor.

     10.  Upon the transfer of all or any part of the indebtedness Pledgee may
transfer all or any part of the collateral and shall be fully discharged
thereafter from all liability and responsibility with respect to such collateral
so transferred, and the transferee shall be vested with all the rights and
powers of Pledgee hereunder with respect to such collateral so transferred; but
with respect to any collateral not so transferred Pledgee shall retain all
rights and powers hereby given.

     11.  Until all indebtedness shall have been paid in full the power of sale
and all other rights, powers and remedies granted to Pledgee hereunder shall
continue to exist and may be exercised by Pledgee at any time and from time to
time irrespective of the fact that the indebtedness or any part thereof may have
become barred by any statute of limitations, or that the personal liability of
the undersigned may have ceased.

     12.  Pledgee agrees that so long as the indebtedness is not in default,
shares of Terayon Communication Systems, Inc. common stock held hereunder as
collateral for the indebtedness shall be released from pledge as the
indebtedness is paid.  Such releases shall be at the rate of one share for each
$____________ of principal amount of indebtedness paid.  Release from pledge,
however, shall not result in release from the provisions of those certain Joint
Escrow Instructions, if any, of even date herewith among the parties to this
Pledge Agreement and the Escrow Agent named therein or from the Purchase Option
of Terayon Communication Systems, Inc., set forth in the Early Exercise Stock
Purchase Agreement dated __________________, 19__, if any, between the parties
to this Pledge Agreement.

     13.  The rights, powers and remedies given to Pledgee by this agreement
shall be in addition to all rights, powers and remedies given to Pledgee by
virtue of any statute or rule of law.  Pledgee may exercise its Pledgee's lien
or right of setoff with respect to the indebtedness in the same manner as if the
indebtedness were unsecured.  Any forbearance or failure or delay by Pledgee in
exercising any right, power or remedy hereunder shall not be deemed to be a
waiver of such right, power or remedy, and any single or partial exercise of any
right, power or remedy hereunder shall not preclude the further exercise
thereof; and every right, power and remedy of Pledgee shall continue in full
force and effect until such right, power or remedy is specifically waived by an
instrument in writing executed by Pledgee.

     Dated:_________________, 19__

                                (INITIAL GRANT)

_______________, Optionee:


     On __________________, 199__, (the "Grant Date") an option was
automatically granted to you (the "optionee") pursuant to the Terayon
Communications Systems (the "Company") 1998 Non-Employee Directors' Stock Option
Plan (the "Plan") to purchase shares of the Company's common stock ("Common
Stock").  This option is not intended to qualify and will not be treated as an
                         ---                              ---                 
"incentive stock option" within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code").  Defined terms not explicitly
defined in this Stock Option Agreement but defined in the Plan shall have the
same definitions as in the Plan.

     The details of your option are as follows:

     1.  The total number of shares of Common Stock subject to this option is
___________ (__________) shares.

     2.  The exercise price of this option is _________________________
($________) per share.

     3.   Thirty-three percent (33%) of the shares subject to this option shall
vest on the first anniversary of the Grant Date and one thirty-sixth (1/36) of
the shares shall vest monthly thereafter over the remaining 24 months, provided
that, during the entire period prior to each such vesting installment date, you
have continuously served as a Non-Employee Director of the Company or employee
or member of the Board of Directors of or consultant to the Company or any
Affiliate of the Company.  If your service as a Non-Employee Director or
employee or member of the Board of Directors of or consultant to the Company or
any Affiliate of the Company terminates for any reason or for no reason, this
option shall be exercisable only to the extent vested on such termination date,
and shall terminate to the extent not exercised on the earlier of the Expiration
Date (as defined below) or the date three (3) months following the date of
termination of all such service; provided, however, if such termination of
service is due to your permanent and total disability, this option shall
terminate on the earlier of the Expiration Date or twelve (12) months following
the date of your permanent and total disability; provided further,  that if such
termination of service is due to your death, this option shall terminate on the
earlier of the Expiration Date or eighteen (18) months following the date of
your death.

     4.   (a)   You may exercise this option, to the extent specified above, by
delivering a notice of exercise (in a form designated by the Company) together
with the exercise price to the Secretary of the Company, or to such other person
as the Company may designate, during regular business hours, together with such
additional documents as the Company may then require pursuant to Section 6 of
the Plan.  You may exercise this option only for whole shares.
<PAGE>
 
          (b)   You may elect to pay the exercise price under one of the
following alternatives:

                (i)   Payment in cash or check at the time of exercise;

                (ii)  Provided that at the time of the exercise the Common Stock
is publicly traded and quoted regularly in The Wall Street Journal, payment by
delivery of shares of Common Stock already owned by you, held for the period
required to avoid a charge to the Company's reported earnings, and owned free
and clear of any liens, claims, encumbrances or security interest, which Common
Stock shall be valued at its Fair Market Value on the date preceding the date of
exercise;

                (iii) Payment pursuant to a program developed under Regulation T
as promulgated by the Federal Reserve Board which results in the receipt of cash
(or check) by the Company either prior to the issuance of shares of the Common
Stock or pursuant to the terms of irrevocable instructions issued by you prior
to the issuance of shares of the Common Stock; or

                (iv)  Payment by a combination of the methods of payment
specified in subparagraphs (i) through (iii) above.

          (c)   By exercising this option you agree that the Company may require
you to enter an arrangement providing for the cash payment by you to the Company
of any tax-withholding obligation of the Company arising by reason of the
exercise of this option.  Notwithstanding anything to the contrary contained
herein, you may not exercise this option unless the shares issuable upon
exercise of this option are then registered under the Securities Act of 1933, as
amended (the "Securities Act"), or, if such shares are not then so registered,
the Company has determined that such exercise and issuance would be exempt from
the registration requirements of the Securities Act.

     5.   Your option is not transferable, except by will or by the laws of
descent and distribution, and is exercisable during your life only by you.
Notwithstanding the foregoing, by delivering written notice to the Company, in a
form satisfactory to the Company, you may designate a third party who, in the
event of your death, shall thereafter be entitled to exercise your option.

     6.   The term of this option ("Expiration Date") is ten (10) years measured
from the Grant Date, subject, however, to earlier termination upon your
termination of service, as set forth in Section 6 of the Plan.

     7.   Any notices provided for in this option or the Plan shall be given in
writing and shall be deemed effectively given upon receipt or, in the case of
notices delivered by the Company to you, five (5) days after deposit in the
United States mail, postage prepaid, addressed to you at the address specified
below or at such other address as you hereafter designate by written notice to
the Company.

     8.   This option is subject to all the provisions of the Plan, a copy of
which is attached hereto, and its provisions are hereby made a part of this
option, including without limitation the provisions of Section 6 of the Plan
relating to option provisions, and is further subject to all interpretations,
amendments, rules and regulations which may from time to time be promulgated and
adopted pursuant to the Plan.  In the event of any conflict between the
provisions of this option and those of the Plan, the provisions of the Plan
shall control.

exercisable in whole or in part unless and until the Company's shareholders have
approved the Plan.

     Dated the ____ day of ____, 19___.

                              Very truly yours,

                               (COMMITTEE GRANT)

_______________, Optionee:


     On __________________, 199__, (the "Grant Date") an option was
automatically granted to you (the "optionee") pursuant to the Terayon
Communications Systems (the "Company") 1998 Non-Employee Directors' Stock Option
Plan (the "Plan") to purchase shares of the Company's common stock ("Common
Stock").  This option is not intended to qualify and will not be treated as an
                         ---                              ---                 
"incentive stock option" within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code").  Defined terms not explicitly
defined in this Stock Option Agreement but defined in the Plan shall have the
same definitions as in the Plan.

     The details of your option are as follows:

     1.   The total number of shares of Common Stock subject to this option is
_______________(______) shares. [Note: pro-rated if less than 12 months
continuous service prior to Grant Date]

     2.   The exercise price of this option is _________________________
($________) per share.

     3.   Thirty-three percent (33%) of the shares subject to this option shall
vest on the first anniversary of the Grant Date and one thirty-sixth (1/36) of
the shares shall vest monthly thereafter over the remaining 24 months, provided
that, during the entire period prior to each such vesting installment date, you
have continuously served as a Non-Employee Director of the Company or employee
or member of the Board of Directors of or consultant to the Company or any
Affiliate of the Company.  If your service as a Non-Employee Director or
employee or member of the Board of Directors of or consultant to the Company or
any Affiliate of the Company terminates for any reason or for no reason, this
option shall be exercisable only to the extent vested on such termination date,
and shall terminate to the extent not exercised on the earlier of the Expiration
Date (as defined below) or the date three (3) months following the date of
termination of all such service; provided, however, if such termination of
service is due to your permanent and total disability, this option shall
terminate on the earlier of the Expiration Date or twelve (12) months following
the date of your permanent and total disability; provided further,  that if such
termination of service is due to your death, this option shall terminate on the
earlier of the Expiration Date or eighteen (18) months following the date of
your death.

     4.   (a)   You may exercise this option, to the extent specified above, by
delivering a notice of exercise (in a form designated by the Company) together
with the exercise price to the Secretary of the Company, or to such other person
as the Company may designate, during regular business hours, together with such
additional documents as the Company may then require pursuant to Section 6 of
the Plan.  You may exercise this option only for whole shares.

                                       9
<PAGE>
 
          (b)   You may elect to pay the exercise price under one of the
following alternatives:

                (i)   Payment in cash or check at the time of exercise;

                (ii)  Provided that at the time of the exercise the Common Stock
is publicly traded and quoted regularly in The Wall Street Journal, payment by
delivery of shares of Common Stock already owned by you, held for the period
required to avoid a charge to the Company's reported earnings, and owned free
and clear of any liens, claims, encumbrances or security interest, which Common
Stock shall be valued at its Fair Market Value on the date preceding the date of
exercise;

                (iii) Payment pursuant to a program developed under Regulation T
as promulgated by the Federal Reserve Board which results in the receipt of cash
(or check) by the Company either prior to the issuance of shares of the Common
Stock or pursuant to the terms of irrevocable instructions issued by you prior
to the issuance of shares of the Common Stock; or

                (iv)  Payment by a combination of the methods of payment
specified in subparagraphs (i) through (iii) above.

          (c)   By exercising this option you agree that the Company may require
you to enter an arrangement providing for the cash payment by you to the Company
of any tax-withholding obligation of the Company arising by reason of the
exercise of this option.  Notwithstanding anything to the contrary contained
herein, you may not exercise this option unless the shares issuable upon
exercise of this option are then registered under the Securities Act of 1933, as
amended (the "Securities Act"), or, if such shares are not then so registered,
the Company has determined that such exercise and issuance would be exempt from
the registration requirements of the Securities Act.

     5.   Your option is not transferable, except by will or by the laws of
descent and distribution, and is exercisable during your life only by you.
Notwithstanding the foregoing, by delivering written notice to the Company, in a
form satisfactory to the Company, you may designate a third party who, in the
event of your death, shall thereafter be entitled to exercise your option.

     6.   The term of this option ("Expiration Date") is ten (10) years measured
from the Grant Date, subject, however, to earlier termination upon your
termination of service, as set forth in Section 6 of the Plan.

     7.   Any notices provided for in this option or the Plan shall be given in
writing and shall be deemed effectively given upon receipt or, in the case of
notices delivered by the Company to you, five (5) days after deposit in the
United States mail, postage prepaid, addressed to you at the address specified
below or at such other address as you hereafter designate by written notice to
the Company.

     8.   This option is subject to all the provisions of the Plan, a copy of
which is attached hereto, and its provisions are hereby made a part of this
option, including without limitation the provisions of Section 6 of the Plan
relating to option provisions, and is further subject to all interpretations,
amendments, rules and regulations which may from time to time be promulgated and
adopted pursuant to the Plan.  In the event of any conflict between the
provisions of this option and those of the Plan, the provisions of the Plan
shall control.

permitted by subparagraph 2(b)(i) through 2(b)(iv) above.

            (c)  In the event that you elect to make payment of the exercise
price pursuant to the deferred payment alternative:

                 (i)   Not less than twenty-five percent (25%) of the aggregate
exercise price shall be due at the time of exercise, not less than twenty-five
percent (25%) of said exercise price, plus accrued interest, shall be due each
year after the date of exercise, and final payment of the remainder of the
exercise price, plus accrued interest, shall be due three (3) years from date of
exercise or, at the Company's election, upon termination of your employment with
the Company or an affiliate;

                 (ii)  Interest shall be payable 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 portion of any
amounts other than amounts stated to be interest under the deferred payment
arrangement; and

                 (iii) In order to elect the deferred payment alternative, you
must, as a part of your written notice of exercise, give notice of the election
of this payment alternative and, in order to secure the payment of the deferred
exercise price to the Company hereunder, if the Company so requests, you must
tender to the Company a promissory note and a security agreement covering the
purchased shares, both in form and substance satisfactory to the Company, or
such other or additional documentation as the Company may request.

      3.   The minimum number of shares with respect to which this option may be
exercised at any one time is one hundred (100), except (a) as to an installment
subject to exercise, as set forth in paragraph 1, which amounts to fewer than
one hundred (100) shares, in which case, as to the exercise of that installment,
the number of shares in such installment shall be the minimum number of shares,
and (b) with respect to the final exercise of this option this minimum shall not
apply.  In no event may this option be exercised for any number of shares which
would require the issuance of anything other than whole shares.

      4.   Notwithstanding anything to the contrary contained herein, this
option may not be exercised unless the shares issuable upon exercise of this
option are then registered under the Act or, if such shares are not then so
registered, the Company has determined that such exercise and issuance would be
exempt from the registration requirements of the Act. You represent that you (i)
are an officer or director of the Company, or (ii) have a preexisting personal
or business relationship with the Company or one or more of its officers,
directors, or controlling persons, or (iii) by reason of your 

                                       2
<PAGE>
 
business or financial experience or the business or financial experience of your
professional advisors who are unaffiliated with and who are not directly or
indirectly compensated by the Company or any affiliate of the Company, you have
the capacity to protect your own interests in connection with the grant of this
option. You also represent that you are acquiring this option for your own
account and not with a view to or for sale in connection with any distribution
of this security. You also represent that you have acquired this option
unaccompanied by the publication of any advertisement. The Company may, upon
advice of counsel to the Company, place legends on stock certificates issued
pursuant to the exercise of this option as such counsel deems necessary and
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of stock.

     5.   The term of this option commences on the date hereof and, unless
sooner terminated as set forth below, terminates on ((7)) (which date shall be
no more than ten (10) years from the date this option is granted). In no event
may this option be exercised on or after the date on which it terminates. This
option shall terminate prior to the expiration of its term as follows: three (3)
months after the termination of your employment with the Company or an affiliate
of the Company for any reason or for no reason unless:

          (a)  such termination of employment is due to your permanent and total
disability (within the meaning of Section 422(c)(6) of the Code), in which event
the option shall terminate on the earlier of the termination date set forth
above or twelve (12) months following such termination of employment; or

          (b)  such termination of employment is due to your death, in which
event the option shall terminate on the earlier of the termination date set
forth above or eighteen (18) months after your death; or

          (c)  during any part of such three (3) month period the option is not
exercisable solely because of the condition set forth in paragraph 5 above, in
which event the option shall not terminate until the earlier of the termination
date set forth above or until it shall have been exercisable for an aggregate
period of three (3) months after the termination of employment; or

          (d)  exercise of the option within three (3) months after termination
of your employment with the Company or with an affiliate would result in
liability under section 16(b) of the Securities Exchange Act of 1934, in which
case the option will terminate on the earlier of (i) the termination date set
forth above, (ii) the tenth (10th) day after the last date upon which exercise
would result in such liability or (iii) six (6) months and ten (10) days after
the termination of your employment with the Company or an affiliate.

     However, this option may be exercised following termination of
employment only as to that number of shares as to which it was exercisable on
the date of termination of employment under the provisions of paragraph 1 of
this option.

     6.   (a)  This option may be exercised, to the extent specified above, by
delivering a notice of exercise (in a form designated by the Company) together
with the exercise price to the Secretary of the Company, or to such other person
as the Company may designate, during regular business hours, together with such
additional documents as the Company may then reasonably require.

                                       3
<PAGE>
 
          (b)  By exercising this option you agree that:

               (i)   the Company may require you to enter an arrangement
providing for the cash payment by you to the Company of any tax withholding
obligation of the Company arising by reason of: (1) the exercise of this option;
(2) the lapse of any substantial risk of forfeiture to which the shares are
subject at the time of exercise; or (3) the disposition of shares acquired upon
such exercise; and

               (ii)  the Company (or a representative of the underwriters) may,
in connection with the first underwritten registration of the offering of any
securities of the Company under the Act, require that you not sell or otherwise
transfer or dispose of any shares of Common Stock or other securities of the
Company during such period (not to exceed one hundred eighty (180) days)
following the effective date (the "Effective Date") of the registration
statement of the Company filed under the Act as may be requested by the Company
or the representative of the underwriters. For purposes of this restriction you
will be deemed to own securities which (1) are owned directly or indirectly by
you, including securities held for your benefit by nominees, custodians, brokers
or pledgees; (2) may be acquired by you within sixty (60) days of the Effective
Date; (3) are owned directly or indirectly, by or for your brothers or sisters
(whether by whole or half blood) spouse, ancestors and lineal descendants; or
(4) are owned, directly or indirectly, by or for a corporation, partnership,
estate or trust of which you are a shareholder, partner or beneficiary, but only
to the extent of your proportionate interest therein as a shareholder, partner
or beneficiary thereof. You further agree that the Company may impose stop-
transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such period.

     7.   During the term of this option, the Company shall keep available at
all times the number of shares of stock required to satisfy the exercise of such
option.

     8.   (a)  If any change is made in the stock subject to this option
(through merger, consolidation, reorganization, recapitalization, stock
dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate
structure or otherwise), this option will be appropriately adjusted in the
class(es), number of shares and price per share of stock subject to the option.

          (b)  In the event of:  (i) a merger or consolidation in which the
Company is not the surviving corporation; or (ii) 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, then, to the extent permitted by applicable law: (1) any surviving
corporation shall assume this option or shall substitute a similar option (if
this option is still outstanding), or (2) this option shall continue in full
force and effect.  In the event any surviving corporation refuses to assume or
continue this option, or to substitute a similar option for this option (if
still outstanding), then this option shall be terminated if not exercised prior
to such event.  In the event of a dissolution or liquidation of the Company,
this option (if still outstanding) shall terminate if not exercised prior to
such event.

     9.   This option is not transferable, except by will or by the laws of
descent and distribution, and is exercisable during your life only by you.  By
delivering written notice to the Company, in a form satisfactory to the Company,
you may designate a third party who, in the event of your death, shall
thereafter be entitled to exercise this option.

                                       4
<PAGE>
 
     10.  This option is not an employment contract and nothing in this option
shall be deemed to create in any way whatsoever any obligation on your part to
continue in the employ of the Company, or of the Company to continue your
employment with the Company.  In the event that this option is granted to you in
connection with the performance of services as a consultant or director, or in
the event that this option is granted to you in connection with the performance
of services as an employee and you subsequently performs services as a
consultant or director, references to employment, employee and similar terms
shall be deemed to include the performance of services as a consultant or a
director, as the case may be, provided, however, that no rights as an employee
shall arise by reason of the use of such terms.

     11.  Any notices provided for in this option shall be given in writing and
shall be deemed effectively given upon receipt or, in the case of notices
delivered by the Company to you, five (5) days after deposit in the United
States mail, postage prepaid, addressed to you at the address specified below or
at such other address as you hereafter designate by written notice to the
Company.

     12.  This option may be amended by the Board of Directors (the "Board")  of
the Company at any time; provided, however, that any change that would adversely
affect your rights in this option must first be approved by you in writing
before becoming effective.

     13.  This option is subject to all interpretations, amendments, rules and
regulations which may from time to time be promulgated and adopted by the
Company.  This authority shall be exercised by the Board, or by a committee of
one or more members of the Board in the event that the Board delegates its
authority to a committee.  The Board, in exercise of this authority, may correct
any defect, omission or inconsistency in this option in a manner and to the
extent the Board shall deem necessary or desirable to make this option fully
effective.  References to the Board shall mean the committee if a committee has
been appointed by the Board.  Any interpretations, amendments, rules and
regulations promulgated by the Board shall be final and binding upon the Company
and its successors in interest as well as you and your heirs, assigns, and other
successors in interest.

     14.  Neither you nor any person to whom this option is transferred under
paragraph 10 of this option 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 this option
unless and until such person has satisfied all requirements for exercise of this
option pursuant to its terms.

                   EARLY EXERCISE STOCK PURCHASE AGREEMENT

     THIS AGREEMENT is made by and between TERAYON COMMUNICATION SYSTEMS, INC.,
a Delaware corporation (the "Corporation"), and ________________ ("Purchaser").

                                 WITNESSETH:

     WHEREAS, Purchaser holds a nonstatutory stock option to purchase shares of
common stock of the Corporation outside the Corporation's 1995 Stock Option Plan
and the Corporation's 1997 Equity Incentive Plan (the "Plans") which Purchaser
desires to exercise; and

     WHEREAS, Purchaser wishes to take advantage of the early exercise provision
of his option and therefore to enter into this Agreement;

     NOW, THEREFORE, IT IS AGREED between the parties as follows:

     1.   Purchaser hereby agrees to purchase from the Corporation, and the
Corporation hereby agrees to sell to Purchaser, an aggregate of
________________________ (______) shares of the common stock (the "Stock") of
the Corporation, for an exercise price of ___________ ($____) per share (total
exercise price:  _________________________________ ($________) payable as
follows:

          Cash at Closing                     $_______________________

          Promissory Note in the form
          of Exhibit E (the "Note")           $_______________________

          Value of _____ shares of Terayon 
          Communication Systems, Inc.
          common stock                        $_______________________

          Total Exercise Price                $_______________________

     The closing hereunder shall occur at the offices of the Corporation on the
date of this Agreement or at such other time and place as the parties may
mutually agree upon in writing.

     At the closing, Purchaser shall deliver three (3) stock assignments in the
form of Exhibit B, duly endorsed (with date and number of shares left blank),
joint escrow instructions (the "Joint Escrow Instructions") in the form of
Exhibit C, duly executed by Purchaser, and the total exercise price (including
an executed Note in the form of Exhibit E if a portion of the total exercise
price is to be paid by promissory note) and an executed pledge agreement in the
form of Exhibit F (the "Pledge Agreement") under which all shares of the Stock
acquired by Note shall be pledged as collateral security for the payment of the
indebtedness represented by the Note; and including endorsed certificates
representing the appropriate number of shares of the Corporation's common stock
if a portion of the total exercise price is to be paid by common stock.

                                       10
<PAGE>
 
     At the closing or as soon thereafter as practicable, the Corporation shall
deliver to the Escrow Agent (as defined in paragraph 8 below) share certificates
for all of the Stock that is to be subject to the Purchase Option (as defined in
paragraph 2 below), and shall deliver share certificates to Purchaser for all of
the Stock, if any, that is not to be subject to the Purchase Option or the
Pledge Agreement.  The certificates for all of the Stock that is subject to the
Pledge Agreement but not the Purchase Option shall be retained by the
Corporation as security pursuant to the Pledge Agreement.

     2.   In accordance with the provisions of section 408(b) of the California
General Corporation Law, the Stock to be purchased by Purchaser pursuant to this
Agreement shall be subject to the following option ("Purchase Option"):

          (a)   In the event that Purchaser shall cease to have a service
relationship with the Corporation for any reason (including his death), or no
reason, with or without cause, the Purchase Option may be exercised.  The
Corporation shall have the right at any time within sixty (60) days after such
cessation of service relationship to purchase from Purchaser or his personal
representative, as the case may be, at the price per share paid by Purchaser
pursuant to this Agreement ("Option Price"), up to but not exceeding the number
of shares of the Stock set forth on Exhibit A hereto which is incorporated
herein by this reference.

          (b)   In addition, and without limiting the foregoing Purchase Option,
if at any time during the term of the Purchase Option, there occurs:  (a) a
dissolution or liquidation of the Corporation; (b) a merger or consolidation
involving the Corporation in which the Corporation is not the surviving
corporation; (c) a reverse merger in which the Corporation is the surviving
corporation but the shares of the Corporation's common stock outstanding
immediately preceding the merger are converted by virtue of the merger into
other property, whether in the form of other securities, cash or otherwise; or
(d) any other capital reorganization in which more than fifty percent (50%) of
the shares of the Corporation entitled to vote are exchanged, then:  (i) if
there is no successor to the Corporation, the Corporation shall have the right
to exercise its Purchase Option as to all or any portion of the Stock then
subject to the Purchase Option set forth above to the same extent as if
Purchaser's service relationship with the Corporation had ceased on the date
preceding the date of consummation of said event or transaction or (ii) the
Purchase Option may be assigned to any successor of the Corporation, and the
Purchase Option shall apply if Purchaser shall cease for any reason to have a
service relationship with such successor on the same basis as set forth above.
In that case, references herein to the "Corporation" shall be deemed to refer to
such successor.

          (c)   The Corporation shall be entitled to pay for any shares
purchased pursuant to its Purchase Option at the Corporation's option in cash,
by offset against any indebtedness given in payment for the Stock, or a
combination of both.

          (d)   As used herein, service relationship and similar terms shall
include acting as a consultant or director of the Corporation.

          (e)   This Agreement is not a service contract and nothing in this
Agreement shall be deemed to create in any way whatsoever any obligation on
the part of Purchaser to continue in the service of the Corporation, or of the
Corporation to continue Purchaser in the service of the Corporation.

                                       11
<PAGE>
 
          (f)   In the event that the Stock's fair market value (as defined in
the Plan) is equal to or exceeds the Option Price on the date that the
Purchaser ceases to have a service relationship with the Corporation, the
Company shall exercise its purchase option to the extent permitted by law.

     3.   The Purchase Option may be exercised by giving written notice of
exercise delivered or mailed as provided in paragraph 14.  Upon providing of
such notice and payment or tender of the purchase price, the Corporation shall
become the legal and beneficial owner of the Stock being purchased and all
rights and interests therein or related thereto.

     4.   If from time to time during the term of the Purchase Option there is
any stock dividend or liquidating dividend or distribution of cash and/or
property, stock split or other change in the character or amount of any of the
outstanding securities of the Corporation, then, in such event, any and all new,
substituted or additional securities or other property to which Purchaser is
entitled by reason of his ownership of Stock will be immediately subject to the
Purchase Option and be included in the word "Stock" for all purposes of the
Purchase Option with the same force and effect as the shares of Stock then
subject to the Purchase Option.  While the total Option Price shall remain the
same after each such event, the Option Price per share of Stock upon exercise of
the Purchase Option shall be appropriately adjusted.

     5.   All certificates representing any shares of Stock of the Corporation
subject to the provisions of this Agreement shall have endorsed thereon legends
in substantially the following form:

                (i)   "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
TO AN OPTION SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE
REGISTERED HOLDER, OR HIS PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE
AT THE PRINCIPAL OFFICE OF THIS CORPORATION. ANY TRANSFER OR ATTEMPTED
TRANSFER OF ANY SHARES SUBJECT TO SUCH OPTION IS VOID WITHOUT THE PRIOR
EXPRESS WRITTEN CONSENT OF THE ISSUER OF THESE SHARES."

                (ii)  "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE
SECURITIES UNDER SAID ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE
CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED."

                (iii) ANY LEGEND REQUIRED TO BE PLACED THEREON BY THE
CALIFORNIA COMMISSIONER OF CORPORATIONS.

     6.   Purchaser acknowledges that he is aware that the Stock to be issued to
him by the Corporation pursuant to this Agreement has not been registered under
the Securities Act of 1933, as amended (the "Act"), on the basis that no
distribution or public offering of the Stock is to be effected, and in this
connection acknowledges that the Corporation is relying on the following
representations.  In this connection, Purchaser warrants and represents to the
Corporation that he 

                                       12
<PAGE>
 
is acquiring the Stock for investment and not with a view to or for sale in
connection with any distribution of the Stock or with any present intention of
distributing or selling the Stock and he does not presently have reason to
anticipate any change in circumstances or any particular occasion or event
which would cause him to sell the Stock. Purchaser recognizes that the Stock
must be held indefinitely unless it is subsequently registered under the Act
or an exemption from such registration is available and, further, recognizes
that the Corporation is under no obligation to register the Stock or to comply
with any exemption from such registration.

     7.   Purchaser is aware that the Stock may not be sold pursuant to Rule 144
adopted under the Act unless certain conditions are met and until Purchaser has
held the Stock for at least two (2) years.  Among the conditions for use of Rule
144 is the availability of specified current public information about the
Corporation.  Purchaser recognizes that the Corporation presently has no plans
to make such information available to the public.

     Whether or not the Purchase Option is exercised or has lapsed, Purchaser
further agrees not to make any disposition of any of the Stock in any event
unless and until:

          (a)   There is then in effect a registration statement under the Act
covering such proposed disposition and such disposition is made in accordance
with such registration statement; or

          (b)   (i)   Purchaser shall have notified the Corporation of the
proposed disposition and shall have furnished the Corporation with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii)
Purchaser shall have given the Corporation an opinion of counsel, which
opinion and counsel shall be satisfactory to the Corporation, to the effect
that such disposition will not require registration of the Stock under the
Act.

     8.   As security for his faithful performance of the terms of this
Agreement and to insure the availability for delivery of Purchaser's Stock
upon exercise of the Purchase Option herein provided for, Purchaser agrees, at
the closing hereunder (or as soon thereafter as practicable), to deliver (or
have the Corporation deliver on the Purchaser's behalf) to and deposit with
the Secretary of the Corporation ("Escrow Agent"), as Escrow Agent in this

shown below his signature or at such other address as such party may designate
by ten (10) days' advance written notice to the other party hereto.

     15.  This Agreement shall bind and inure to the benefit of the successors
and assigns of the Corporation and, subject to the restrictions on transfer

Terayon Communication Systems, Inc.

Santa Clara, CA  95054
Attn:  Secretary

Dear Sir or Madam:

     As Escrow Agent for both Terayon Communication Systems, Inc., a Delaware
corporation ("Corporation"), and the undersigned purchaser of stock of the
Corporation ("Purchaser"), you are hereby authorized and directed to hold the
documents delivered to you pursuant to the terms of that certain Early Exercise
Stock Purchase Agreement ("Agreement"), dated ____________________, 199__, to
which a copy of these Joint Escrow Instructions is attached as Exhibit C, in
accordance with the following instructions:

     1.   In the event the Corporation or an assignee shall elect to exercise
the Purchase Option set forth in the Agreement, the Corporation or its
assignee will give to Purchaser and you a written notice specifying the number
of shares of stock to be purchased, the purchase price, and the time for a
closing hereunder at the principal office of the Corporation. Purchaser and
the Corporation hereby irrevocably authorize and direct you to close the
transaction contemplated by such notice in accordance with the terms of said
notice.

     2.   At the closing you are directed (a) to date any stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Corporation against the
simultaneous delivery to you of the purchase price (which may include suitable
acknowledgment of cancellation of indebtedness) of the number of shares of stock
being purchased pursuant to the exercise of the Purchase Option.

     3.   Purchaser irrevocably authorizes the Corporation to deposit with you
any certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as specified in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as his attorney-in-
fact and agent for the term of this escrow to execute with respect to such
securities and other property all documents of assignment and/or transfer and
all stock certificates necessary or appropriate to make all securities
negotiable and complete any transaction herein contemplated.

     4.   This escrow shall terminate upon expiration or exercise in full of the
Purchase Option, whichever occurs first.

     5.   If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Purchaser,
you shall deliver all of same to Purchaser and shall be discharged of all
further obligations hereunder; provided, however, that if at the time of
termination of this escrow you are advised by the Corporation that the property

                                       18
<PAGE>
 
subject to this escrow is the subject of a pledge or other security agreement,
you shall deliver all such property to the pledgeholder or other person
designated by the Corporation.

     6.   Except at otherwise provided in these Joint Escrow Instructions, your
duties hereunder may be altered, amended, modified or revoked only by a writing
signed by all of the parties hereto.

     7.   You shall be obligated only for the performance of such duties as are
specifically set forth herein and may rely and shall be protected in relying or
refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties or
their assignees.  You shall not be personally liable for any act you may do or
omit to do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while
acting in good faith and any act done or omitted by you pursuant to the advice
of your own attorneys shall be conclusive evidence of such good faith.

     8.   You are hereby expressly authorized to disregard any and all warnings
given by any of the parties hereto or by any other person or corporation,
excepting only orders or process of courts of law, and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court.
In case you obey or comply with any such order, judgment or decree of any court,
you shall not be liable to any of the parties hereto or to any other person,
firm or corporation by reason of such compliance, notwithstanding any such
order, judgment or decree being subsequently reversed, modified, annulled, set
aside, vacated or found to have been entered without jurisdiction.

     9.   You shall not be liable in any respect on account of the identity,
authority or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

     10.  You shall not be liable for the outlawing of any rights under any
statute of limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

     11.  You shall be entitled to employ such legal counsel (including without
limitation the firm of Cooley Godward llp) and other experts as you may deem
necessary properly to advise you in connection with your obligations hereunder,
may rely upon the advice of such counsel, and may pay such counsel reasonable
compensation therefor.

     12.  Your responsibilities as Escrow Agent hereunder shall terminate if you
shall cease to be Secretary of the Corporation or if you shall resign by written
notice to each party.  In the event of any such termination, the Corporation may
appoint any officer or assistant officer of the Corporation as successor Escrow
Agent and Purchaser hereby confirms the appointment of such successor or
successors as his attorney-in-fact and agent to the full extent of your
appointment.

     13.  If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

     14.  It is understood and agreed that should any dispute arise with respect
to the delivery and/or ownership or right of possession of the securities, you
may (but are not obligated 

                                       19
<PAGE>
 
to) retain in your possession without liability to anyone all or any part of
said securities until such dispute shall have been settled either by mutual
written agreement of the parties concerned or by a final order, decree or
judgment of a court of competent jurisdiction after the time for appeal has
expired and no appeal has been perfected, but you shall be under no duty
whatsoever to institute or defend any such proceedings.

     15.  Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon personal delivery or upon deposit in

stock, new securities or other property except cash dividends other than
liquidating dividends to which the undersigned is or may hereafter become
entitled to receive on account of such property, and in the event that the
undersigned receives any such, the undersigned will immediately deliver it to
Pledgee to be held by Pledgee hereunder in the same manner as the property
originally pledged hereunder.  All property assigned, transferred to and pledged
with Pledgee under this paragraph is hereinafter called "collateral."

     2.   At any time, without notice, and at the expense of the undersigned,
Pledgee in its name or in the name of its nominee or of the undersigned may, but
shall not be obligated to:  (1) collect by legal proceedings or otherwise all
dividends (except cash dividends other than liquidating dividends), interest,
principal payments and other sums now or hereafter payable upon or on account of
said collateral; (2) enter into any extension, reorganization, deposit, merger,
or consolidation agreement, or any agreement in any wise relating to or
affecting the collateral, and in connection therewith may deposit or surrender
control of such collateral thereunder, accept other property in exchange for
such collateral and do and perform such acts and things as it may deem proper,
and any money or property received in exchange for such collateral shall be
applied to the indebtedness or thereafter held by it pursuant to the provisions
hereof; (3) insure, process and preserve the collateral; (4) cause the
collateral to be transferred to its name or to the name of its nominee; (5)
exercise as to such collateral all the rights, powers, and remedies of an owner,
except that so long as the indebtedness is not in default the undersigned shall
retain all voting rights as to the collateral.

     3.   The undersigned agrees to pay prior to delinquency all taxes, charges,
liens and assessments against the collateral, and upon the failure of the
undersigned to do so Pledgee at its option may pay any of them and shall be the
sole judge of the legality or validity thereof and the amount necessary to
discharge the same.

     4.   All advances, charges, costs and expenses, including reasonable
attorneys' fees, incurred or paid by Pledgee in exercising any right, power or
remedy conferred by this agreement, or in the enforcement thereof, shall become
a part of the indebtedness secured hereunder and shall be paid to Pledgee by the
undersigned immediately and without demand.

     5.   At the option of Pledgee and without necessity of demand or notice,
all or any part of the indebtedness of the undersigned shall immediately
become due and payable irrespective of any agreed maturity, upon the happening
of any of the following events: (1) failure to keep or perform any of the
terms or provisions of this agreement; (2) default in the 

                                       26

payment of principal or interest when due; (3) the levy of any attachment,
execution or other process against the collateral; or (4) the insolvency,
commission of an act of bankruptcy, general assignment for the benefit of
creditors, filing of any petition in bankruptcy or for relief under the
provisions of Title 11, United States Code, Bankruptcy, of, by, or against the
undersigned.

     6.   In the event of the nonpayment of any indebtedness when due, whether
by acceleration or otherwise, or upon the happening of any of the events
specified in the last preceding paragraph, Pledgee may then, or at any time
thereafter, at its election, apply, set off, collect or sell in one or more
sales, or take such steps as may be necessary to liquidate and reduce to cash
in the hands of Pledgee in whole or in part, with or without any previous
demands or demand of performance or notice or advertisement, the whole or any
part of the collateral in such order as Pledgee may elect, and any such sale
may be made either at public or private sale at its place of business or
elsewhere, or at any broker's board or securities exchange, either for cash or
upon credit or for future delivery; provided, however, that if such
disposition is at private sale, then the purchase price of the collateral
shall be equal to the public market price then in effect, or, if at the time
of sale no public market for the collateral exists, then, in recognition of
the fact that the sale of the collateral would have to be registered under the
Securities Act of 1933 and that the expenses of such registration are
commercially unreasonable for the type and amount of collateral pledged
hereunder, Pledgee and the undersigned hereby agree that such private sale
shall be at a purchase price mutually agreed to by Pledgee and the undersigned
or, if the parties cannot agree upon a purchase price, then at a purchase
price established by a majority of three independent appraisers knowledgeable
of the value of such collateral, one named by the undersigned within 10 days
after written request by the Pledgee to do so, one named by Pledgee within
such 10 day period, and the third named by the two appraisers so selected,
with the appraisal to be rendered by such body within 30 days of the
appointment of the third appraiser. The cost of such appraisal, including all
appraiser's fees, shall be charged against the proceeds of sale as an expense
of such sale. Pledgee may be the purchaser of any or all collateral so sold
and hold the same thereafter in its own right free from any claim of the
undersigned or right of redemption. Demands of performance, notices of sale,
advertisements and presence of property at sale are hereby waived, and Pledgee
is hereby authorized to sell hereunder any evidence of debt pledged to it. Any
sale hereunder may be conducted by any officer or agent of Pledgee.

     7.   The proceeds of the sale of any of the collateral and all sums
received or collected by Pledgee from or on account of such collateral shall
be applied by Pledgee to the payment of expenses incurred or paid by Pledgee
in connection with any sale, transfer or delivery of the collateral, to the
payment of any other costs, charges, attorneys' fees or expenses mentioned
herein, and to the payment of the indebtedness or any part hereof, all in such
order and manner as Pledgee in its discretion may determine. Pledgee shall pay
any balance to the undersigned.

     8.   Pledgee shall be under no duty or obligation whatsoever to make or
give any presentments, demands for performance, notices of non-performance,
protests, notices of protest or notices of dishonor in connection with any
obligations or evidences of indebtedness held by Pledgee as collateral, or in
connection with any obligations or evidences of indebtedness which constitute
in whole or in part the indebtedness secured hereunder.

     9.   Pledgee may at any time deliver the collateral or any part thereof to
the undersigned and the receipt of the undersigned shall be a complete and full
acquittance for the 

                                       27
<PAGE>
 
collateral so delivered, and Pledgee shall thereafter be discharged from any
liability or responsibility therefor.

     10.  Upon the transfer of all or any part of the indebtedness Pledgee may
transfer all or any part of the collateral and shall be fully discharged
thereafter from all liability and responsibility with respect to such collateral
so transferred, and the transferee shall be vested with all the rights and
powers of Pledgee hereunder with respect to such collateral so transferred; but
with respect to any collateral not so transferred Pledgee shall retain all
rights and powers hereby given.

     11.  Until all indebtedness shall have been paid in full the power of sale
and all other rights, powers and remedies granted to Pledgee hereunder shall
continue to exist and may be exercised by Pledgee at any time and from time to
time irrespective of the fact that the indebtedness or any part thereof may have
become barred by any statute of limitations, or that the personal liability of
the undersigned may have ceased.

     12.  Pledgee agrees that so long as the indebtedness is not in default,
shares of Terayon Communication Systems, Inc. common stock held hereunder as
collateral for the indebtedness shall be released from pledge as the
indebtedness is paid.  Such releases shall be at the rate of one share for each
$____________ of principal amount of indebtedness paid.  Release from pledge,
however, shall not result in release from the provisions of those certain Joint
Escrow Instructions, if any, of even date herewith among the parties to this
Pledge Agreement and the Escrow Agent named therein or from the Purchase Option
of Terayon Communication Systems, Inc., set forth in the Early Exercise Stock
Purchase Agreement dated __________________, 19__, if any, between the parties
to this Pledge Agreement.

     13.  The rights, powers and remedies given to Pledgee by this agreement
shall be in addition to all rights, powers and remedies given to Pledgee by
virtue of any statute or rule of law.  Pledgee may exercise its Pledgee's lien
or right of setoff with respect to the indebtedness in the same manner as if the
indebtedness were unsecured.  Any forbearance or failure or delay by Pledgee in
exercising any right, power or remedy hereunder shall not be deemed to be a
waiver of such right, power or remedy, and any single or partial exercise of any
right, power or remedy hereunder shall not preclude the further exercise
thereof; and every right, power and remedy of Pledgee shall continue in full
force and effect until such right, power or remedy is specifically waived by an
instrument in writing executed by Pledgee.

     Dated:______________, 19__
