1997 STOCK PLAN

SENIOR EXECUTIVE STOCK OPTION AGREEMENT

Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Option Agreement.

You (“You” or “Optionee”) have been granted an option to purchase Common Stock of the Company, subject to the terms and conditions of the Plan and this Option Agreement, as follows:

Exercise and Vesting Schedule:

This Option is exercisable immediately, in whole or in part, and shall vest according to the following vesting schedule:

1. 25% of the Shares subject to the Option shall vest on the first anniversary of the Vesting Commencement Date, and 1/48 of the Shares subject to the Option shall vest each month thereafter, subject to your Continuous Status as an Employee or Consultant (“Continuous Status”) on such dates.

2. In addition to the time-based vesting described in the preceding paragraph, if you are still an Employee or Consultant on the date of a Change of Control, and if before the one-year

anniversary of the Change of Control either (a) the Company, its successor or the acquiror terminates you as an Employee and/or Consultant (so your Continuous Service ends) without Cause, or (b) the Company, its successor or the acquiror takes actions that constitute Constructive Termination, then on the date of your termination or Constructive Termination, your Option will vest as to 100% of the Shares.

3. “Change of Control” means the occurrence of any of the following events (except in each case as a result of the sale by the Company of its securities for the purpose of raising additional funds):

(a) Any “person” or “group” as such terms are defined under Sections 13 and 14 of the Securities Exchange Act of 1934 (the “Exchange Act”) (other than the Company, a Subsidiary of the Company, or a Company employee benefit plan) which did not previously possess such securities becomes the “beneficial owner” (as defined in Exchange Act Rule 13d-3), directly or indirectly, of Company securities representing a majority of the combined voting power of the Company’s then outstanding securities;

(b) The closing of (i) the sale of all or substantially all of the assets of the Company if the holders of Company securities representing all voting power for the election of directors before the transaction hold less than a majority of the total voting power for the election of directors of all entities which acquire such assets, or (ii) the merger of the Company with or into another corporation if the holders of Company securities representing all voting power for the election of directors before the transaction hold less than a majority of the total voting power for the election of directors of the surviving entity; or

(c) The issuance of securities which would give a “person” or “group” beneficial ownership of Company securities representing 50% or more of all voting power for the election of directors; or

(d) Election of individuals representing a majority of the board of directors if those directors were nominated by a “person” or “group” and the incumbent board of directors publicly opposed the election of those directors.

4. “Cause” means:

(a) Your willful or grossly negligent failure to perform your assigned significant duties or responsibilities after two notices at least 30 days apart from the Company describing your failure to perform such significant duties or responsibilities;

(b) You engage in any act of gross dishonesty, fraud or gross misrepresentation which has an adverse effect on the Company;

5. “Constructive Termination” means:

(a) A material reduction in your duties, position or authority relative to your duties, position or authority in effect immediately prior to such reduction; provided, however, that a reduction in your position or authority solely by virtue of the Company being made part of a larger entity shall not constitute “Constructive Termination” (as, for example, following the Change of Control, when the Chief Executive Officer of the Company remains in a similar authoritative position with respect to an entity or business unit that is similar in size as the Company, and has similar authority within the larger entity as other individuals at similar levels within such larger entity, but does not continue to be the Chief Executive Officer of the Company, its successor or an acquiring corporation);

(b) A material reduction in the facilities and perquisites (including office space, staff and location) available to you immediately prior to such reduction, excluding an across-the-board reduction of facilities and perquisites affecting all executive officers of the acquiring corporation similarly;

(c) A requirement that you relocate your principal working location more than 75 miles from the Company facility at which you were working at the time of the Change of Control; or

(d) Any reduction in your base salary, target bonus or benefits as in effect immediately prior to such reduction (other than a benefits reduction applied consistently to all employees at the same level).

6. Termination Period:

You may exercise this Option for three months after your Continuous Status as an Employee or Consultant terminates. Upon your death or disability, this Option may be exercised for such longer period as provided in the Plan. In no event may you exercise this Option after the Term/Expiration Date as provided above.

1. Grant of Option. The Plan Administrator of the Company hereby grants to the Optionee named in the Notice of Grant (the “Optionee”), an option (the “Option”) to purchase the 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 terms and conditions of the Plan, which is incorporated herein by reference. In the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail.

If designated in the Notice of Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code.

-3-

Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”).

2. Exercise of Option. This Option shall be exercisable during its term in accordance with the provisions of Section 9 of the Plan as follows:

(a) Right to Exercise.

(i) Subject to subsections 2(a)(ii) and 2(a)(iii) below, this Option shall be exercisable cumulatively according to the vesting schedule set forth in the Notice of Grant. Alternatively, at the election of the Optionee, this option may be exercised in whole or in part at any time as to Shares which have not yet vested (“Unvested Shares”). For purposes of this Stock Option Agreement, Shares subject to the Option shall vest (“Vested Shares”) based on continued employment of Optionee with the Company. Vested Shares shall not be subject to the Company’s repurchase right (as set forth in the Restricted Stock Purchase Agreement, attached hereto as Exhibit C-1).

(ii) As a condition to exercising this Option for Unvested Shares, the Optionee shall execute the Restricted Stock Purchase Agreement.

(iii) This Option may not be exercised for a fraction of a Share.

(b) Method of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) which shall state the election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price.

No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise complies with 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.

3. Optionee’s Representations. 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, if required by the Company, 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.

4. 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

-4-

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.

5. 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:

(a) cash; or

(b) check.

6. [Intentionally Omitted]

7. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the shareholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law.

8. 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, successors and assigns of the Optionee.

9. 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 the terms of this Option.

10. Tax Consequences. Set forth below is a brief summary as of the date of this Option of some of the federal tax consequences of exercise of this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

(a) Exercise of ISO. If this Option qualifies as an ISO, there will be no regular federal income tax liability upon the exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as an adjustment to the alternative minimum tax for federal tax purposes and may subject the Optionee to the alternative minimum tax in the year of exercise.

(b) Exercise of ISO Following Disability. If the Optionee ceases to be an Employee as a result of a disability that is not a total and permanent disability as defined in Section 22(e)(3) of the Code, to the extent permitted on the date of termination, the Optionee must exercise an ISO within three months of such termination for the ISO to be qualified as an ISO.

-5-

(c) Exercise of Nonstatutory Stock Option. There may be a regular federal income tax liability upon the exercise of a Nonstatutory Stock Option. The Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. If Optionee is an Employee or a former Employee, the Company will be required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount in cash equal to a percentage of this compensation income at the time of exercise, and may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise.

(d) Disposition of Shares. In the case of an NSO, if Shares are held for at least one year, any gain realized on disposition of the Shares will be treated as long-term capital gain for federal income tax purposes. In the case of an ISO, if Shares transferred pursuant to the Option are held for at least one year after exercise and at least two years after the Date of Grant, any gain realized on disposition of the Shares will also be treated as long-term capital gain for federal income tax purposes. If Shares purchased under an ISO are disposed of within one year after exercise or two years after the Date of Grant, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the difference between the Exercise Price and the lesser of (i) the Fair Market Value of the Shares on the date of exercise, or (ii) the sale price of the Shares. Any additional gain will be taxed as capital gain, short-term depending on the period that the ISO Shares were held.

(e) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two years after the Date of Grant, or (ii) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that Optionee may be subject to income tax withholding by the Company on the compensation income recognized by the Optionee.

(f) Section 83(b) Election for Unvested Shares Purchased Pursuant to Options. With respect to the exercise of an Option for unvested Shares, an election may be filed by the Optionee with the Internal Revenue Service, within 30 days of the purchase of the Shares, electing pursuant to Section 83(b) of the Code to be taxed currently on any difference between the purchase price of the Shares and their Fair Market Value on the date of purchase. In the case of a Nonstatutory Stock Option, this will result in a recognition of taxable income to the Optionee on the date of exercise, measured by the excess, if any, of the fair market value of the Shares, at the time the Option is exercised over the purchase price for the Shares. Absent such an election, taxable income will be measured and recognized by Optionee at the time or times on which the Company’s Repurchase Option lapses. In the case of an Incentive Stock Option, such an election will result in a recognition of income to the Optionee for alternative minimum tax purposes on the date of exercise, measured by the excess, if any, of the fair market value of the Shares, at the time the option is exercised, over the purchase price for the Shares. Absent such an election, alternative minimum taxable income will be measured and recognized by Optionee at the time or times on which the Company’s Repurchase Option lapses. Optionee is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing

-6-

of the Election under Section 83(b) of the Code. A form of Election under Section 83(b) is attached hereto as Exhibit C-5 for reference.

OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON OPTIONEE’S BEHALF.

11. Entire Agreement; Governing Law. The Plan is incorporated herein by reference. 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 [state].

12. 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 A SERVICE PROVIDER AT THE WILL OF THE COMPANY (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 ENGAGEMENT AS A SERVICE PROVIDER 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 RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

Optionee acknowledges receipt of a copy of the Plan 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 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 Administrator upon any questions arising under the Plan or this Option. Optionee further agrees to notify the Company upon any change in the residence address indicated below.

Effective as of today, _________ __, 200__, the undersigned «First» «Last» (“Optionee”) hereby elects to exercise Optionee’s option to purchase _________ shares of the Common Stock (the “Shares”) of Alien Technology Corporation (the “Company”) under and pursuant to the 1997 Stock Plan (the “Plan”) and the [    ] Incentive [    ] Nonstatutory Stock Option Agreement dated «Date_of_Grant» (the “Option Agreement”).

2. Delivery of Payment. Purchaser herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement.

3. Representations of Optionee. Optionee acknowledges that Optionee has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions.

4. Rights as Shareholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be issued to the Optionee as soon as practicable after the Option is exercised. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as provided in Section 12 of the Plan.

5. Company’s Right of First Refusal. The Company is hereby granted the right of first refusal (the “First Refusal Right”), exercisable in connection with any proposed sale or other transfer of the Shares in which the Optionee has vested. For purposes of this Section 5, the term “transfer” shall include any assignment, pledge, encumbrance or other disposition for the value of the Shares intended to be made by the Optionee. Nothing in this Section 5 shall be construed to confer upon the Optionee the right to transfer any shares that remain unvested under Section 4 of this Agreement.

(a) Notice of Proposed Transfer. In the event the Optionee desires to accept a bona fide third-party offer for any or all of the Shares which have vested (the shares subject to such offer to be hereinafter called, solely for the purpose of this Section 5, the “Target Shares”), such offer may be accepted only in accordance with the provisions of this Section 5, and only after the Optionee has promptly (i) delivered to the Secretary of the Company written notice (the “Disposition Notice”) of the offer and the basic terms and conditions thereof, including the proposed purchase

price and (ii) provided satisfactory proof that the disposition of the Target Shares to the third-party offeror would not be in contravention of the provisions set forth in this Agreement, and, that such third-party offeror (including any parent company, subsidiary, division, joint venture, or other affiliate thereof) is not engaged in any business or activity (including any announced business or activity) which directly or indirectly competes with the products or services of the Company, as the Company shall determine in its reasonable discretion.

(b) Exercise of Right of First Refusal; Payment. The Company (or its assignees) shall, for a period of thirty (30) days following receipt of the Disposition Notice, have the right to repurchase not less than all of the Target Shares specified in the Disposition Notice upon substantially the same terms and conditions specified therein. Such right shall be exercisable by written notice (the “Exercise Notice”) delivered to Optionee prior to the expiration of the thirty (30) day exercise period. If such right is exercised with respect to all the Target Shares specified in the Disposition Notice, then the Company (or its assignees) shall effect the repurchase of the Target Shares, including payment of the purchase price, not more than five (5) business days after the delivery of the Exercise Notice; and at such time Optionee shall deliver to the Company the certificates representing the Target Shares to be repurchased, each certificate to be properly endorsed for transfer. To the extent any of the Target Shares are at the time held in escrow, the certificates for such shares shall automatically be released from escrow and surrendered to the Company for cancellation. The Target Shares so purchased shall thereupon be canceled and cease to be issued and outstanding shares of the Company’s Common Stock.

(c) Purchase Price. Should the purchase price specified in the Disposition Notice be payable in property other than cash or evidences of indebtedness, the Company (or its assignees) shall have the right to pay the purchase price in the form of cash equal in amount to the value of such property. If the Optionee and the Company (or its assignees) cannot agree on such cash value within ten (10) days after the Company’s receipt of the Disposition Notice, the valuation shall be made by an appraiser of recognized standing selected by the Optionee and the Company (or its assignees), or, if they cannot agree on an appraiser within twenty (20) days after the Company’s receipt of the Disposition Notice, each shall select an appraiser of recognized standing and the two appraisers shall designate a third appraiser of recognized standing, whose appraisal shall be determinative of such value. The cost of such appraisal shall be shared equally by the Optionee and the Company. The closing shall then be held on the later of (i) the fifth business day following delivery of the Exercise Notice or (ii) the 15th day after such cash valuation shall have been made.

(d) Optionee’s Right to Transfer. In the event the Exercise Notice is not given to Optionee within thirty (30) days following the date of the Company’s receipt of the Disposition Notice, Optionee shall have a period of thirty (30) days thereafter, in which to sell or otherwise dispose of the Target Shares upon terms and conditions (including the purchase price) no more favorable to the third-party purchaser than those specified in the Disposition Notice; provided, however, that any such sale or disposition must not be effected in contravention of the provisions of this Agreement. To the extent any of the Target Shares are at the time held in escrow under Section 7, the certificates for such shares shall automatically be released from escrow and surrendered to the Optionee. In the event Optionee does not sell or otherwise dispose of the Target Shares within the specified thirty (30) day period, the Company’s First Refusal Right shall continue

-2-

to be applicable to any subsequent disposition of the Target Shares by Optionee until such right lapses in accordance with Section 5(f).

(e) Effect of Stock Dividend, Stock Split or Recapitalization. In the event of any stock dividend, stock split, recapitalization or other transaction affecting the Company’s outstanding Common Stock as a class effected without receipt of consideration, then any new, substituted or additional securities or other property which is by reason of such transaction distributed with respect to the Target Shares shall be immediately subject to the Company’s First Refusal Right hereunder.

(f) Termination of Right of First Refusal. The First Refusal Right under this Section 5 shall lapse and cease to have effect upon the earliest to occur of (i) the first date on which shares of the Company’s Common Stock are held of record by more than five hundred (500) persons, (ii) a determination is made by the Company’s Board of Directors that a public market exists for the outstanding shares of the Company’s Common Stock or (iii) a firm commitment underwritten public offering pursuant to an effective registration statement under the Securities Act, covering the offer and sale of the Company’s Common Stock. However, the market stand-off provisions of Section 4 of the Option Agreement shall continue to remain in full force and effect following the lapse of the First Refusal Right hereunder.

6. Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s purchase or disposition of the Shares. Optionee represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the Company for any tax advice.

7. Restrictive Legends and Stop-Transfer Orders.

(a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND RIGHT OF FIRST REFUSAL OPTIONS HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER

-3-

RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES.

(b) Stop-Transfer Notices. Optionee agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

(c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

8. Successors and Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement shall be binding upon Optionee and his or her heirs, executors, administrators, successors and assigns.

9. Interpretation. Any dispute regarding the interpretation of this Agreement shall be submitted by Optionee or by the Company forthwith to the Administrator which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator shall be final and binding on all parties.

10. Governing Law; Severability. This Agreement is governed by the internal substantive laws, but not the choice of law rules, of California.

11. Entire Agreement. The Plan and Option Agreement are incorporated herein by reference. This Agreement, the Plan, the Restricted Stock Purchase Agreement, the Option Agreement and the Investment Representation Statement 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.

EXHIBIT B

INVESTMENT REPRESENTATION STATEMENT

In connection with the purchase of the above-listed Securities, the undersigned Optionee represents to the Company the following:

(a) Optionee is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”).

(b) Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption there from, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection, Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the Securities unless they are registered or such registration is not required in the opinion of counsel satisfactory to the Company.

(c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of

Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company, (3) the amount of Securities being sold during any three month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable.

In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144.

(d) Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any such other registration exemption will be available in such event.

ALIEN TECHNOLOGY CORPORATION

1997 STOCK PLAN

RESTRICTED STOCK PURCHASE AGREEMENT

THIS AGREEMENT is made between «First» «Last» (the “Purchaser”) and Alien Technology Corporation (the “Company”) as of ________________ __, 200__.

RECITALS

(1) Pursuant to the exercise of the stock option granted to Purchaser under the Company’s 1997 Stock Plan (the “Plan”) and pursuant to the Stock Option Agreement (the “Option Agreement”) dated «Date_of_Grant» by and between the Company and Purchaser with respect to such grant, which Plan and Option Agreement are hereby incorporated by reference, Purchaser has elected to purchase _________ of those shares which have not become vested under the vesting schedule set forth in the Option Agreement (“Unvested Shares”). The Unvested Shares and the shares subject to the Option Agreement which have become vested are sometimes collectively referred to herein as the “Shares”.

(2) As required by the Option Agreement, as a condition to Purchaser’s election to exercise the option, Purchaser must execute this Restricted Stock Purchase Agreement, which sets forth the rights and obligations of the parties with respect to Shares acquired upon exercise of the Option.

1. Repurchase Option.

(a) If Purchaser’s status as a Service Provider is terminated for any reason, including for cause, death, and disability, the Company shall have the right and option to purchase from Purchaser, or Purchaser’s personal representative, as the case may be, all of the Purchaser’s Unvested Shares as of the date of such termination at the price paid by the Purchaser for such Shares (the “Repurchase Option”).

The closing shall take place at the Company’s office. At the closing, the holder of the certificates for the Unvested Shares being transferred shall deliver the stock certificate or certificates evidencing the Unvested Shares, and the Company shall deliver the purchase price therefor.

(c) At its option, the Company may elect to make payment for the Unvested Shares to a bank selected by the Company. The Company shall avail itself of this option by a notice

in writing to Purchaser stating the name and address of the bank, date of closing, and waiving the closing at the Company’s office.

(e) The Repurchase Option shall terminate in accordance with the Vesting Schedule in Optionee’s Option Agreement.

2. Transferability of the Shares; Escrow.

(a) Purchaser hereby authorizes and directs the secretary of the Company, or such other person designated by the Company, to transfer the Unvested Shares as to which the Repurchase Option has been exercised from Purchaser to the Company.

(b) To insure the availability for delivery of Purchaser’s Unvested Shares upon repurchase by the Company pursuant to the Repurchase Option under Section 1, Purchaser hereby appoints the secretary, or any other person designated by the Company as escrow agent, as its attorney-in-fact to sell, assign and transfer unto the Company, such Unvested Shares, if any, repurchased by the Company pursuant to the Repurchase Option and shall, upon execution of this Agreement, deliver and deposit with the secretary of the Company, or such other person designated by the Company, the share certificates representing the Unvested Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit C-2. The Unvested Shares and stock assignment shall be held by the secretary in escrow, pursuant to the Joint Escrow Instructions of the Company and Purchaser attached as Exhibit C-3 hereto, until the Company exercises its purchase right as provided in Section 1, until such Unvested Shares are vested, or until such time as this Agreement no longer is in effect. As a further condition to the Company’s obligations under this Agreement, the spouse of the Purchaser, if any, shall execute and deliver to the Company the Consent of Spouse attached hereto as Exhibit C-4. Upon vesting of the Unvested Shares, the escrow agent shall promptly deliver to the Purchaser the certificate or certificates representing such Shares in the escrow agent’s possession belonging to the Purchaser, and the escrow agent shall be discharged of all further obligations hereunder; provided, however, that the escrow agent shall nevertheless retain such certificate or certificates as escrow agent if so required pursuant to other restrictions imposed pursuant to this Agreement.

(c) The Company, or its designee, shall not be liable for any act it may do or omit to do with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its judgment.

(d) Transfer or sale of the Shares is subject to restrictions on transfer imposed by any applicable state and federal securities laws. Any transferee shall hold such Shares subject to all the provisions hereof and the Exercise Notice executed by the Purchaser with respect to any Unvested Shares purchased by Purchaser and shall acknowledge the same by signing a copy of this Agreement.

3. Ownership, Voting Rights, Duties. This Agreement shall not affect in any way the ownership, voting rights or other rights or duties of Purchaser, except as specifically provided herein.

4. Legends. The share certificate evidencing the Shares issued hereunder shall be endorsed with the following legend (in addition to any legend required under applicable state securities laws):

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

5. Adjustment for Stock Split. All references to the number of Shares and the purchase price of the Shares in this Agreement shall be appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares which may be made by the Company after the date of this Agreement.

6. Notices. Notices required hereunder shall be given in person or by registered mail to the address of Purchaser shown on the records of the Company, and to the Company at their respective principal executive offices.

7. Survival of Terms. This Agreement shall apply to and bind Purchaser and the Company and their respective permitted assignees and transferees, heirs, legatees, executors, administrators and legal successors.

8. Section 83(b) Election. Purchaser hereby acknowledges that he or she has been informed that, with respect to the exercise of an Option for unvested Shares, an election may be filed by the Purchaser with the Internal Revenue Service, within 30 days of the purchase of the Shares, electing pursuant to Section 83(b) of the Code to be taxed currently on any difference between the purchase price of the Shares and their Fair Market Value on the date of purchase. In the case of a Nonstatutory Stock Option, this will result in a recognition of taxable income to the Purchaser on the date of exercise, measured by the excess, if any, of the fair market value of the Shares, at the time the Option is exercised over the purchase price for the Shares. Absent such an election, taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. In the case of an Incentive Stock Option, such an election will result in a recognition of income to the Purchaser for alternative minimum tax purposes on the date of exercise, measured by the excess, if any, of the fair market value of the Shares, at the time the option is exercised, over the purchase price for the Shares. Absent such an election, alternative minimum taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. Purchaser is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing of the Election under Section 83(b) of the Code. A form of Election under Section 83(b) is attached hereto as Exhibit C-5 for reference.

PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER’S BEHALF.

9. Representations. Purchaser has reviewed with his own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement. Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Purchaser understands that he (and not the Company) shall be responsible for his own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

10. Governing Law. This Agreement shall be governed by the internal substantive laws, but not the choice of law rules, of California.

Purchaser represents that he has read this Agreement and is familiar with its terms and provisions. Purchaser hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under this Agreement.

IN WITNESS WHEREOF, this Agreement is deemed made as of the date first set forth above.
