SPIRENT STOCK OPTION PLAN
STOCK OPTION AGREEMENT

Unless expressly provided herein, the terms defined in the Spirent Stock Option Plan (the "Plan") shall have the same defined meanings in this Stock Option Agreement (the "Option Agreement").

1. NOTICE OF STOCK OPTION GRANT
(the "Optionee")

The undersigned Optionee has been granted an option (which, for residents of the United States of America is a Non-Qualified Stock Option (the "NQSO)) to purchase Ordinary shares (the "Shares") of Spirent plc (the "Company"), subject to the rules of the Plan and this Option Agreement, as follows:


Grant Reference No
Date of Grant
Total Number of Shares Granted under option
Exercise Price		xxxxx per share
Vesting Commencement Date
Term/Expiration Date

Exercise Price:

The Exercise Price per Share of the Option granted hereunder is the Fair Market Value ("FMV") of a Spirent plc Ordinary share at the close of business on the date the Option is granted.

Vesting Schedule:

This Option shall be exercisable over a period of four years, as to 25% from the Vesting Commencement Date and monthly thereafter in equal proportions (i.e. 1 × 48^th per month of the total number of Shares granted), provided the Optionee remains in employment.

Termination Period:

This Option shall terminate, subject to this Option Agreement and to the Plan rules, when Optionee ceases to be an employee. In no event may Optionee exercise this Option after the Term/Expiration Date as provided above.

2. AGREEMENT

(a) Grant of Option. The Company hereby grants to the Optionee named in the Notice of Grant an option (the "Option") to purchase the total number of Shares set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the "Exercise Price"), and subject to the rules of the Plan, which is incorporated herein by reference. In the event of a conflict between the rules of the Plan and this Option Agreement, the rules of the Plan shall prevail.

Residents of the United States of America are advised that if designated in the Notice of Grant as an Incentive Stock Option ("Incentive Options"), this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the

$100,000 rule of Code Section 422(d), this Option shall be treated as a Nonqualifying Stock Option ("NQSO").

(b) Exercise of Option.

(i) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Grant and with the applicable provisions of the Plan and this Option Agreement.

(ii) Method of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the "Exercise Notice") accompanied by cleared payment of the aggregate Exercise Price as to all Exercised Shares. The Option shall be declared exercised by the Company upon its receipt of such fully executed Exercise Notice and the corresponding aggregate Exercise Price.

No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise complies with all applicable laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the Option is exercised with respect to such Shares.

(c) Optionee's Representations. Residents of the United States of America are advised that in the event the Shares have not been registered under the Securities Act of 1933, as amended, at the time this Option is exercised, the Optionee shall, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit B.

(d) Lock-Up Period. Optionee hereby agrees that, if so requested by the Company or any representative of the underwriters (the "Managing Underwriter") in connection with any registration of the offering of any securities of the Company under the Securities Act, Optionee shall not sell or otherwise transfer any Shares or other securities of the Company during the 180-day period (or such other period as may be requested in writing by the Managing Underwriter and agreed to in writing by the Company) (the "Market Standoff Period") following the effective date of a registration statement of the Company filed under the Securities Act. Such restriction shall apply only to the first registration statement of the Company to become effective under the Securities Act that includes securities to be sold on behalf of the Company to the public in an underwritten public offering under the Securities Act. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff Period.

(e) Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee:

(i): cash or check; or
(ii): consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan.

(f) Restrictions on Exercise. This Option may not be exercised if the issuance of Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any applicable law or the Company's Articles of Association. Notwithstanding the foregoing, to the extent necessary to comply with applicable laws with respect to the grant of the Option and the Optionees acquisition of Shares upon the exercise of the Option granted hereunder, the Company shall have the right to delay or suspend the exercisability of the Option in the manner set forth in the Plan.

(g) Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, and successors of the Optionee.

(h) Term of Option. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and this Option Agreement.

(i) Tax Consequences. The Optionee should consult a tax advisor about the tax consequences of exercise of this Option and disposition of the Shares.

(j) Post-Termination Exercise Period. Notwithstanding Section 2(a), if an Optionee voluntarily terminates his or her employment or is discharged unless such termination is for cause as defined by applicable law, any Option which is capable of being exercised as at the time of termination shall be exercisable for sixty (60) days from the date of termination. If the Optionee's employment terminates due to Optionee's death or disability, each Option may be exercised, to the extent that it was exercisable on the date of such death or termination of employment, for one year after the Optionee ceases to be an employee and if exercise of such Option is delayed under the terms of Article V Section 3 of the Plan and pursuant to Section 6 above, the period of post-termination exercise shall be tolled during any such period of delay in accordance with the applicable provisions of Article V Section 3. Nothing in this Section 10 shall be construed to allow any Option to be exercised later than the expiration of the term of this Option. Any portion of an Option that is not exercisable on the date the Optionee ceases to be an employee shall be forfeited on such date of termination. If the Optionee's employment is terminated for cause, all outstanding Options, whether exerciseable or not, shall be forfeited at date of termination.

(k) Entire Agreement; Governing Law. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee's interest except by means of a writing signed by the Company and Optionee. This agreement is governed by the internal substantive laws but not the choice of law rules of the State of Delaware.

(l) No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS AN EMPLOYEE OF THE COMPANY OR ANY EMPLOYING COMPANY OF THE SPIRENT plc GROUP OF COMPANIES (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED EMPLOYMENT FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S OR, AS AFORESAID, ANY EMPLOYING COMPANY'S RIGHT TO TERMINATE OPTIONEE'S RELATIONSHIP AS AN EMPLOYEE AT ANY TIME, WITH OR WITHOUT CAUSE.

OPTIONEE ACKNOWLEDGES THAT HE/SHE IS NOT INDUCED TO PURCHASE THE SECURITIES BY EXPECTATION OF EMPLOYMENT OR CONTINUED EMPLOYMENT WITH THE COMPANY, OR AS AFORESAID ANY EMPLOYING COMPANY.

Optionee acknowledges that a copy of the Plan has been made available to him or her and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Remuneration Committee

upon any questions arising under the Plan or this Option Agreement. Optionee further agrees to notify the Company and the Plan Administrator upon any change in the residence address indicated below.
