                                                                             -3-

<PAGE>
[*** Redacted] prior to the date when the Collaboration is then scheduled to
commence (provided that if this Agreement is signed by Intel after November 30,
2003, Intel shall be entitled to provide the initial such notice on the date of
such signature, but only if such signature date is on or before December 10,
2003), Intel shall be entitled to delay commencement of the Collaboration to any
date on or before March 31, 2004. Delays resulting in commencement of the
Collaboration after December 31, 2003 shall be subject to the payments in
Section 3.2 below. It is understood and agreed that commencement of the
Collaboration may not be delayed past March 31, 2004.

the Collaboration, where "X" is a number between [*** Redacted] and
[*** Redacted], inclusive, chosen by Intel by written notice to Nanosys at least
[*** Redacted] days prior to the beginning of such fourth quarter. If Intel
fails to provide such notice, "X" will be deemed to equal [*** Redacted].

                  2.3 It is the parties' mutual intent that most of the work and
deliverable creation under this Agreement to investigate [*** Redacted] memory
feasibility shall occur at the Nanosys Facility. Nanosys shall host Intel's
Listed Representatives on a mutually agreed upon basis, such agreement not to be
unreasonably withheld, on site at the Nanosys Facility to work on this project
and get deeply involved in complementary collaborative activities (e.g., device
integration and characterization, but not the synthesis of Deposited
Nanomaterials). Information on the design and modeling of Deposited
Nanomaterials, as well as [*** Redacted], [*** Redacted], and [*** Redacted]
related to Deposited Nanomaterials, shall be provided to Intel's Listed
Representatives, but in each case only as reasonably required for device
integration and characterization for the purpose of the Collaboration, including
but not limited to, making an informed decision about the complexity of
integrating Deposited Nanomaterials with Conventional Processes. Nanosys' Listed
Representatives may also be invited to work at Intel's facilities, for
circumstances including but not limited to, using a metrology tool that may not
be available at the Nanosys Facility. The parties shall adhere to the following
guidelines in connection with Listed Representatives working at the site of the
other party: (a) all employees of one party visiting the other party's facility
shall comply with the rules and regulations applicable at that facility as
communicated to such employees, and each party retains the right to reasonably
refuse admittance for violation of these rules; (b) the hosting party shall
maintain reasonable firewall procedures so that employees of a visiting party
are not exposed to the confidential information of a third party; (c) each party
shall maintain reasonable firewall procedures so that third parties at a party's
site are not exposed to the confidential information of the other party or
non-public information about the status of this Collaboration; and (d) in the
case of Nanosys only, cubicle space, secure Internet access, and badge access
shall be made available for use by Intel's Listed Representatives when such a
person or persons are working on site at the Nanosys Facility.

                  2.4 Except as set forth in Section 5, any and all materials
supplied by one party to the other party shall be used by the recipient only to
perform its Collaboration obligations.

                  2.5 Except as set forth in Section 3 below, each party shall
bear its own costs and expenses in carrying out the Collaboration.

                  2.6 Except for University/Government Activities, each party
agrees to work exclusively with the other party in the Field of Interest during
the Exclusivity Period.

                  2.7 The following persons ("Collaboration Managers") shall be
appointed to direct the conduct of the parties with respect to the
Collaboration:

                                                2625 Hanover Street
                                                Palo Alto, CA 94304

The Collaboration Managers shall have the authority to approve in writing
changes to Exhibit A, including, as applicable, specifications, scope of work,
and milestones. The Collaboration Managers shall have no other authority to
amend this Agreement. Each party may change its Collaboration Manager on written
notice to the other party, provided that the replacement Collaboration Manager
is at a similar level of authority at the party making the replacement, or as
otherwise agreed by the parties.

                  2.8 If either party desires to propose changes to the
Collaboration, it shall notify the other party in writing of such proposal and
the reasons for such proposal. The other party will give each such proposal its
prompt attention. If Intel and Nanosys agree to any such change, the change
shall be evidenced by a written confirmation signed by the Collaboration
Managers of both parties. Such a written confirmation shall amend the terms of
Exhibit A.

                  2.9 If the Collaboration is completed successfully (i.e.,
neither party has terminated this Agreement under Section 10, and the parties
agree that the subject technology is promising and warrants pursuing further),
then it is the parties' intent that, at Intel's request, the parties will
negotiate, in good faith, during the Exclusivity Period to enter into a
follow-on development agreement (the "Development Agreement") to further develop
and commercialize the technology

                                                                             -5-

<PAGE>

which is the subject of this Agreement If Intel requests such a negotiation,
then, for the duration of the Exclusivity Period, Nanosys agrees that Nanosys
will not enter into any discussions regarding the subject of the Collaboration
with any third party. The parties further intend that any such Development
Agreement would reflect that, if the development and commercialization of this
technology are successful, and Intel has a good-faith intent to use the
Collaboration Materials in anticipation of a high-volume manufacturing ramp,
then:

                           (a)      It is the parties' mutual intent that the
parties would negotiate in good faith a supply agreement that reasonably assures
the supply of Deposited Nanomaterials and any related Nanosys enabling
technology or rights to Intel (for use in the Field of Interest, the
"Collaboration Materials"). Upon Intel's request to commence such negotiations,
the parties would negotiate diligently and in good faith to reach agreement.
Further, if at the expiration of the Development Agreement the parties have not
reached agreement, notwithstanding their diligent and good faith efforts, then
Nanosys would not enter into any supply agreement, within six (6) months after
the expiration of the Development Agreement, to supply Collaboration Materials
to any third party, in the Field of Interest, on terms which are more favorable
to that third party than the terms last offered by Nanosys to Intel during this
negotiation. In the first instance, the parties would use reasonable efforts to
qualify Nanosys as a supplier to Intel of the Collaboration Materials. Nanosys
acknowledges that, in order to be selected as an Intel qualified supplier,
Nanosys must demonstrate supply capability (in areas including, but not limited
to, cost, quality, and availability). Nanosys further acknowledges that the
supply agreement would include a "most favored customer" provision which
guarantees that, at any time, Nanosys' price to Intel for Collaboration
Materials is no higher than the price charged by Nanosys to any third party for
Collaboration Materials, in the Field of Interest, on similar terms and
conditions. Further, if the parties enter into a supply agreement, the supply
agreement will include provisions to help ensure a reliable supply of
Collaboration Materials to Intel, which may include (i) safety stock and (ii) if
Nanosys is unable to reasonably provide Intel with the Collaboration Materials,
then upon notice from Intel, Nanosys' would take prompt action to arrange for
such supply, which may include designating a subcontractor, subject to Intel's
consent of such subcontractor (which shall not be unreasonably withheld), to
manufacture such quantity of Collaboration Materials that cannot be obtained
from Nanosys, providing such subcontractor agrees to pay Nanosys a reasonable
royalty and agrees to reasonable confidentiality, intellectual property
protection, and commercial provisions. Nanosys agrees to fully reasonably
cooperate with Intel and the chosen subcontractor in the transfer of technology
and sufficient collaborative engineering resources necessary to allow the
subcontractor to produce Collaboration Materials for Intel's intended use as
soon as practicable after Intel's request. Nanosys reserves the right to seek
any and all legal recourse against the subcontractor if confidentiality or other
provisions of the agreement between Nanosys and the subcontractor are violated.

                           (b)      It is the parties' mutual intent that, if
the parties have not entered into a supply agreement as set forth in Section
2.9(a), notwithstanding their diligent and good faith efforts, then upon Intel's
request within [*** Redacted] after the expiration of the Development
Agreement, Nanosys would designate a contract manufacturer, subject to Intel's
consent of such contract manufacturer (which would not be unreasonably
withheld), to manufacture Collaboration Materials, licensing such contract
manufacturer to applicable Nanosys intellectual property on reasonable and
non-discriminatory terms, provided that such contract manufacturer agrees to pay
Nanosys a reasonable royalty and agrees to reasonable confidentiality,
intellectual property

                                                                             -6-

protection, and commercial provisions. Nanosys shall fully and reasonably
cooperate with Intel and the chosen contract manufacturer in the transfer of
technology and sufficient collaborative engineering resources necessary to allow
the contract manufacturer to produce Collaboration Materials for Intel's
intended use as soon as practicable after Intel's request. Nanosys reserves the
right to seek all legal recourse against the contract manufacturer if
confidentiality or other provisions of the license between Nanosys and the
contract manufacturer are violated. If Nanosys fails to enter into a license
with a contract manufacturer as contemplated in this Section 2.9(b) within
[*** Redacted] after Intel's request to Nanosys, then Nanosys would be deemed
not to be entering the business of high-volume supply of Collaboration
Materials.

                           (c)      The parties further intend that if Nanosys
chooses not to enter into the business of supply of Collaboration Materials, and
Nanosys does not license the necessary enabling technology to a third party
manufacturer as provided in Section 2.9(b) above, then Nanosys would provide to
Intel a royalty-bearing, capped fee, worldwide, perpetual, non-exclusive license
under Nanosys IP, to have made Collaboration Materials and to make, have made,
use, sell, offer to sell and import, products using or incorporating
Collaboration Materials.

         3.       PAYMENTS TO NANOSYS.

                  3.1 Intel shall pay to Nanosys the following payments at the
following times:

* $[*** Redacted] per FTE, according to the number of FTEs chosen by Intel,
pursuant to Section 2.2 above, for the fourth quarter of the Collaboration.

For the avoidance of doubt, the latter two payments (of $[*** Redacted] and
([*** Redacted])) will not be due if Intel terminates this Agreement under
Section 10.2 below.

                  3.2 For each month (or portion thereof) that Intel delays the
Collaboration Commencement Date, pursuant to Section 2.1 above, to a date after
December 31,2003, Intel shall pay to Nanosys [*** Redacted] dollars
($[*** Redacted]) (prorated on a day for day basis for partial months). Such
payment shall be due and payable within thirty (30) days after Intel's notice of
delay. (By way of example only, if upon execution of this Agreement Intel
notified Nanosys of a Collaboration Commencement Date delay to January 15,
2004, Intel would pay Nanosys $[*** Redacted] within thirty (30) days after such
notice date. If on December 15,2003 Intel then notified Nanosys of a further
delay

<PAGE>

in the Collaboration Commencement Date, until March 10, 2004, Intel would
pay to Nanosys an additional $[*** Redacted] by January 14, 2004 (i.e., in
this example, a total of $[*** Redacted]).)

                  3.3 As of the Effective Date, the "Exclusivity Expiration"
shall be fifteen (15) months after the Exclusivity Date.

                           (i)      Intel shall be entitled to extend the
Exclusivity Expiration by three (3) months, to twenty-one (21) months after the
Exclusivity Date, by written notice to Nanosys no later than seventeen (17)
months after the Exclusivity Date, and payment to Nanosys of [*** Redacted]
dollars ($[*** Redacted]). This payment shall be due and payable no later than
eighteen (18) months after the Exclusivity Date.

                           (ii)     If Intel has extended the Exclusivity
Expiration pursuant to paragraph (i) hereinabove, then Intel shall be entitled
to further extend the Exclusivity Expiration by an additional [*** Redacted], to
[*** Redacted] after the Exclusivity Date, by written notice to Nanosys no later
than [*** Redacted] after the Exclusivity Date, and payment to Nanosys of [***
Redacted] dollars ($[*** Redacted]). This payment will be due and payable no
later than [*** Redacted] after the Exclusivity Date.

                           (iii)    If Intel has extended the Exclusivity
Expiration pursuant to paragraph (ii) hereinabove, then Intel shall be entitled
to further extend the Exclusivity Expiration by an additional [*** Redacted], to
[*** Redacted] after the Exclusivity Date, by written notice to Nanosys no later

event, Intel shall be deemed to have granted to Nanosys a nonexclusive (except
as set forth hereinbelow), irrevocable, perpetual, fully paid, royalty free
license, with right to sublicense (and authorize the granting of further
sublicenses), only under such Collaboration Right, without restriction,

                           (i)      Nanosys shall have the sole right to
prosecute claims of infringement or misappropriation of Collaboration IP, where
such infringement or misappropriation is primarily in Nanosys' Exclusive Field.
In each such case, Intel shall, at Nanosys' expense, take all actions reasonably
requested by Nanosys in such prosecution, subject to indemnification by Nanosys
of Intel for any liability to third parties resulting from such participation.

                           (ii)     Intel shall have the sole right to prosecute
claims of infringement or misappropriation of Collaboration IP where such
infringement or misappropriation is primarily in Intel's Exclusive Field. In
each such case, Nanosys shall, at Intel's expense, take all actions reasonably
requested by Intel in such prosecution (which may include participation as a
named plaintiff, subject to indemnification by Intel of Nanosys for any
liability to third parties resulting from such participation as a plaintiff).



                                                                            -11-

consents, documents or further instruments of license, assignment, and transfer,

other party's expense and as the other party may reasonably deem necessary or
desirable in order for the other party to obtain the full benefits of Section
4.2 and this Section 7 and the activities contemplated thereby.

EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING WITHOUT LIMITATION ANY
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. WITHOUT
LIMITING THE FOREGOING, ALL DELIVERABLES AND OTHER ITEMS ARE PROVIDED BY EACH
PARTY "AS IS," AND ALL LICENSES GRANTED BY EACH PARTY ARE GRANTED "AS IS."

DAMAGES OR LIABILITIES, INCLUDING WITHOUT LIMITATION SUCH DAMAGES OR LIABILITIES
FOR LOSS OF REVENUE, LOSS OF BUSINESS, FRUSTRATION OF ECONOMIC OR BUSINESS
EXPECTATIONS, LOSS OF PROFITS, OR COST OF CAPITAL, REGARDLESS OF THE FORM OF THE
ACTION, WHETHER IN CONTRACT OR OTHERWISE, EVEN IF ANY REPRESENTATIVE OF A PARTY
HERETO HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN NO EVENT SHALL
EITHER PARTY'S LIABILITY UNDER THIS AGREEMENT EXCEED THE AMOUNTS PAID OR PAYABLE
BY INTEL TO NANOSYS UNDER THIS AGREEMENT, provided that, as to Intel, this shall
be in addition to Intel's obligation to pay such amounts. These limitations,
however, shall not apply to either party's liability, if any, (i) for
contribution or indemnity with respect to liability to third parties for
personal injury, death, or damage to tangible property, (ii) exceeding the scope
of the licenses in Section 5 (Licenses), (iii) breach of Section 6 (Confidential

creditors; then the other party may terminate this Agreement by notice to the
non-terminating party.

                  10.4 Termination Due to Breach. Either party shall have the
right to terminate this Agreement if the other party is in material breach of
any material term or condition of this Agreement and fails to remedy such breach
within thirty (30) days after receipt of written notice of such breach given by

                  11.3 Amendment; Waiver. This Agreement may be amended,
modified or supplemented only by a writing that is signed by duly authorized
representatives of both parties and that specifically identifies the provision
or provisions of this Agreement being amended, modified or supplemented. No term
or provision hereof will be considered waived by either party, and no breach
excused by either party, unless such waiver or consent is in writing signed on
behalf of the party against whom the waiver is asserted. Without limiting the
foregoing, no consent by either party to, or waiver of, a breach by either
party, whether express or implied, will constitute a consent to, waiver of, or
excuse of any other, different, or subsequent breach by either party.

                  11.4 Severability. If any provision hereof should be held
invalid, illegal or unenforceable in any jurisdiction, the parties shall
negotiate in good faith a valid, legal and enforceable substitute provision that
most nearly reflects the original intent of the parties and all other provisions
hereof shall remain in full force and effect in such jurisdiction and shall be
liberally construed in order to carry out the intentions of the parties hereto
as nearly as may be possible. Such invalidity, illegality or unenforceability
shall not affect the validity, legality or enforceability of such provision in
any other jurisdiction.

                  11.5 Governing Law. This Agreement shall be governed by and
construed under the laws of the United States and the State of California, not
including its conflict of law provisions.

                  11.6 Force Majeure. Except for the payment of sums accrued,
neither party will be liable for any failure or delay in performance under this
Agreement due to fire, explosion, earthquake, storm, flood or other weather,
unavailability of necessary utilities or raw materials, war, insurrection, riot,
act of God or the public enemy, law, act, order, proclamation, decree,
regulation, ordinance, or instructions of government or other public
authorities, or any other event beyond the reasonable control of the party whose
performance is to be excused. If, however, a party's performance is prevented
for sixty (60) days, then the other party shall be entitled to terminate this
Agreement on written notice to the party suffering the force majeure at any time
prior to resumption of performance by the party suffering the force majeure.

                  11.7 Assignment. Neither party may transfer or assign this
Agreement, whether by operation of law or otherwise, without the prior written
consent of the other party and any attempt to do so without such consent will be
void. This Agreement will bind and inure to the benefit of the parties and their
respective permitted successors and permitted assigns. Notwithstanding anything
in this Agreement, however, either party may assign this Agreement without the
other party's prior written consent to a successor to all or substantially all
of its assets pertaining to the Collaboration (e.g., the surviving entity in a
merger or consolidation in which it participates or to a purchaser of all or
substantially all of its assets pertaining to the Collaboration), so long as
such surviving entity or purchaser shall assume (expressly in writing or by
operation of law) the performance of all of the terms of this Agreement.

                  11.8 No Third Party Beneficiaries. No person or entity other
than Intel and Nanosys will have any rights or obligations pursuant to this
Agreement.

                  11.9 Relationship of the Parties. The parties to this
Agreement are independent contractors. There is no relationship of agency,
partnership, joint venture, employment, or franchise between the parties and
this Agreement is negotiated at arm' s length with both sides represented by
counsel of their choice. Neither party has the authority to bind the other or to
incur any obligation on its behalf. Any such act will create a separate
liability in the party so acting to any and all third parties affected thereby.

                  11.10 Counterparts. This Agreement may be executed in two
counterparts, each of which shall be deemed an original, but both of which
together shall constitute one and the same instrument. If this Agreement is
executed in counterparts, no signatory hereto shall be bound until both the
parties named below have duly executed or caused to be duly executed a
counterpart of this Agreement.

                  11.11 Confidentiality of Agreement. Subject to Section 6.1(v)
and Section 11.1, each party agrees that the existence of and the terms and
conditions of this Agreement shall be treated as confidential, provided,
however, that each party may disclose the terms and conditions of this
Agreement: (i) as required by any court or other governmental body; (ii) as
otherwise required by law; (iii) to legal counsel of the parties; (iv) in
connection with the requirements of a public offering or securities filing; (v)
in confidence, to accountants, banks, and financing sources and their advisors;
(vi) in confidence, in connection with the enforcement of this Agreement or
rights under this Agreement; or (vii) in confidence, in connection with a merger
or acquisition or proposed merger or acquisition, or the like.

                  11.12 Authority. Each party represents and warrants to the
other party at the Effective Date (i) that it has the legal right, power, and
authority to enter into this Agreement and to fully perform its obligations
under this Agreement, and (ii) that the performance of such obligations will not
conflict with any agreements, contracts or other arrangements to which it is a
party or by which it is bound.

                  11.13 Entire Agreement. This Agreement, including all Exhibits
to this Agreement, together with the CNDA (as set forth in Section 6 above),
constitutes the entire agreement between the parties relating to this subject
matter and supersedes all prior or simultaneous representations,


                                                                            -15-

                  Collaboration Statement of Work (SOW) Summary

         Construction of [*** Redacted] devices (similar to the concept figure
below) to evaluate key technical areas required for a [*** Redacted] memory unit
and to project the performance limits of the technology.

                                 [*** Redacted]

         Device will have an [*** Redacted] and will be utilized to evaluate:

         -        [*** Redacted] and [*** Redacted].

         -        [*** Redacted] characteristics (e.g. [*** Redacted], etc.)

         -        [*** Redacted] - including [*** Redacted] characteristics.

         -        Effects of [*** Redacted], and [*** Redacted] modifications.

         -        Variations of [*** Redacted].

         -        [*** Redacted] (e.g. [*** Redacted])

         -        Variations of processing means.

         and to construct a model for [*** Redacted] of a [*** Redacted] or [***
Redacted] device.

In Q1 and Q2, the project would focus on modeling and generating/testing
[*** Redacted] in order to reconcile the validity of the model. Q3 and Q4 would
focus on a [*** Redacted] to better select [*** Redacted]. The [*** Redacted]
work would be done on [*** Redacted] devices in a [*** Redacted]. A more
detailed plan of activities will be generated by the Collaboration team upon
Commencement of the Collaboration.

*** Confidential treatment requested pursuant to a request for confidential
treatment filed with the Securities and Exchange Commission. Omitted portions
