ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.


     The Registrant's Certificate of Incorporation provides for the
indemnification of directors to the fullest extent permissible under Delaware
law.



     The Registrant's Bylaws provides for the indemnification of officers,
directors and third parties acting on behalf of the Registrant if such person
acted in good faith and in a manner reasonably believed to be in and not opposed
to the best interest of the Registrant, and, with respect to any criminal action
or proceeding, the indemnified party had no reason to believe his or her conduct
was unlawful.


     The Registrant has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for in
the Registrant's Bylaws, and intends to enter into indemnification agreements
with any new directors and executive officers in the future.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

     Since inception, we have issued unregistered securities to a limited number
of persons as described below:

     None of these transactions involved any underwriters, underwriting
discounts or commissions, or any public offering, and we believe that each
transaction was exempt from the registration requirements of the Securities Act
by virtue of Section 4(2) thereof, Regulation D promulgated thereunder or Rule
701 pursuant to compensatory benefit plans and contracts relating to
compensation as provided under such Rule 701. The recipients of securities in
each such transaction represented their intention to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof, and appropriate legends were affixed to the share
certificates and instruments issued in such transactions. All recipients had
adequate access, through their relationships with us, to information about us.

ITEM 17. UNDERTAKINGS

     The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions referenced in Item 14 of
this Registration Statement 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 a director,
officer or controlling person in connection with the securities being registered
hereunder, 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.

     The undersigned Registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of Prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a

                                  CONFIDENTIAL

                        AGREEMENT ON TERMS AND CONDITIONS
                   OF PURCHASE AND SALE OF OPTICAL COMPONENTS

        This Agreement ("Agreement") is made as of this 1st day of January, 2000
by and between Corning Incorporated, a New York Corporation, with an address at
Houghton Park, Corning, NY 14831 ("Corning") and New Focus, Inc. with an address
at 2630 Walsh Avenue, Santa Clara, CA 95051 ("Seller").

        WHEREAS, Corning and certain of its affiliated companies plan to place
with Seller from time to time during the terms of this Agreement specific orders
for the purchase of certain Optical Components ("Materials"); and

        WHEREAS, the parties wish to provide for the general terms and
conditions upon which such Materials purchase transactions shall be made; and

        WHEREAS, the parties may wish to subsequently provide for certain
services for processing or additional goods and services related to the
Materials;

        NOW THEREFORE, in consideration of the mutual covenants herein, Corning
and Seller hereby agree as follows:

1.   Term. The Term of this Agreement shall be from January 1, 2000 through
     December 31, 2000 If the parties are not in breach at the expiration of the
     Term, then they may mutually agree in writing to continue this Agreement,
     upon thirty (30) days' notice prior to the term expiration date, for an
     additional one (1) year term.

2.   Scope. During the Term of this Agreement, the terms and conditions
     specified by this Agreement shall apply to all purchases of the Materials
     by Corning from Seller. This Agreement is based upon an anticipated
     procurement of Materials described in Appendix 1. The estimated quantity of
     each item of Materials to be purchased hereunder is described in the same
     Appendix. That estimated quantity for each item is based on an allocation
     to Seller of a share (expressed as a percentage) of Corning's purchases
     from unaffiliated companies of that item. Corning anticipates that this
     share allocation to the Seller will not change during the term of this
     Agreement provided the Seller can meet its delivery and other obligations
     under this Agreement, and can continuously keep Corning competitive in the
     market place. Corning may conduct business reviews with the Seller on a
     periodic basis (monthly, quarterly, semi-annually) to review the overall
     market situation and discuss changes needed to maintain a competitive
     position in the communications industry.

3.   Releases. When Corning wishes to purchase Materials pursuant to this
     Agreement, it shall submit a written release form for a specific quantity
     to Seller. Seller shall ship Materials in accordance with the Corning
     release. Release forms may be delivered to Seller via fax, email, EDI, or
     U.S. mail.

4.   Schedule and Safety Stock. Corning's schedules depend upon timely delivery
     of Materials and therefore, time is of the essence in Corning's release
     forms issued to Seller hereunder. Seller agrees to make timely delivery in
     accordance with agreed

<PAGE>   2


     upon delivery dates. In order to assure Corning of continuity of supply,
     Seller will keep as a safety stock a four-week supply of finished goods of
     each Material exclusively for Corning for which Corning shall be
     responsible to purchase upon termination or Material discontinuance.
     Corning will authorize and update, on a quarterly basis, the safety stock
     level required by product that the Seller will have available to ship. If
     this level exceeds four (4) weeks of the demand, Corning shall only be
     obligated to purchase the authorized four (4) weeks supply upon termination
     or material discontinuance.

5.   Price(s) and Quantity. During the Term, the guaranteed prices, and
     estimated quantities of the Materials sold by Seller to Corning shall be as
     specified in Appendix I hereto.

6.   Delivery. Unless otherwise agreed, all price and delivery terms shall be on
     a delivered basis, broken out specifying price, insurance, and freight
     separately.

7.   Performance. Corning will provide a minimum of 3 weeks lead time on new
     purchase orders and 2 weeks lead time on schedule changes on forecasts.

     Corning will provide at least a three (3) month or greater rolling Forecast
     reflecting, by time period, shipping quantities required for each part
     number to support Corning's manufacturing schedules.

     Seller agrees to make timely deliveries in accordance with agreed upon
     delivery dates.

8.   Title. Title to and possession of all Materials shipped by Seller to
     Corning shall pass to Corning upon delivery of materials at the Corning
     location.

9.   Warranty/Specifications. At the time of delivery, Seller warrants that
     title to the Materials shall pass to Corning, free and clear of claims or
     liens of third parties. Seller also warrants that the Materials supplied by
     Seller to Corning hereunder shall meet the quality levels and specification
     levels defined in Appendix II. Materials shall be free of objects or other
     substances which, in the opinion of Corning, could render them until for
     intended use. If quality levels are not defined in Appendix II for a
     particular item, then Seller warrants that such Materials shall be
     merchantable, of best quality and free from defects in materials,
     processing or workmanship. This warranty shall survive any inspection by
     Corning.

     Any attempt by Seller to limit, disclaim, or restrict any such warranties
     or any remedies of Corning, by acknowledgment or otherwise, in accepting or
     performing this order, shall be null, void and ineffective without
     Corning's written consent.

     The initial warranty period of Materials shipped under the terms and
     conditions of this Agreement will be [*] from the date of shipment by
     Supplier. Any purchased device which is rejected for non-conformance to
     Corning's specification will be returned to Seller. Seller will, at
     Corning's option and without limiting any other rights of Corning, either:
     (1) credit Corning the value of device, (2) replace the device at no
     expense to Corning, or (3) repair the device at no cost to Corning.

10.  Software & Systems Warranty. Seller warrants that the quality and delivery
     of the Material will not be affected by any computer system and/or software
     related

[*] Certain information on this page has been omitted and
    filed separately with the Commission. Confidential treatment
    has been requested with respect to the omitted portions.
<PAGE>   3

     malfunction including, but not limited to, changes in dates, the passing of
     the calendar years 1999 or 2000, the next millennium and/or leap years.
     Should Seller fail to meet the requirements of this Agreement due to such
     computer system and/or software related malfunctions, Corning may (without
     prejudice to any other available remedy or cause of action) terminate this
     Agreement on five (5) days advance written notice to Seller. Additionally,
     Corning may terminate this Agreement if Seller, when requested, fails to
     give adequate assurance that it or any of its suppliers are Year 2000
     compliant.

11.  Inspection. Corning shall be entitled to inspect Materials upon delivery.
     Any prior inspection of Materials or sampling at the Seller's facility by
     Corning personnel will imply neither delivery or acceptance of such
     Materials by Corning.

12.  Plant Access. Seller will allow representatives of Corning and Corning's
     customers access to the facilities involved in performing this order for
     purposes of reviewing the status and progress of production and witnessing
     any test and inspections. Such access will not relieve Seller of any of its
     obligations.

13.  Inspection Reports. Seller shall furnish Corning with Inspection Reports
     for each shipment of Materials hereunder. Seller shall collect all relevant
     data for each Material prior to shipment. Such Certificates of Analysis
     shall be specific by traceable notations and Corning may reject items that
     do not meet the specifications in Appendix II. Inspection reports shall
     accompany all Materials shipped to Corning. Duplicate copies shall be filed
     and stored by Seller for a period of seven (7) years in case future
     reference is required by Corning.

14.  Invoicing and Payment. Seller shall invoice Corning in duplicate for
     Materials ordered by and delivered to Corning. Corning shall pay such
     invoices within forty-five (45) days after their receipt. Corning shall not
     be required to pay invoices for any Materials which do not meet applicable
     specifications or for quantities other than those it ordered.

15.  Process Changes. Seller shall notify Corning in writing and at least 30
     days in advance of any change in its manufacturing, assurance of supply,
     refining, feedstock, process or equipment that might affect Corning's
     results, its access to, or its use of the Materials purchased from Seller
     hereunder.

16.  Design Changes. In the event that Corning's requirements for Materials
     change, Corning and Seller shall meet in good faith to discuss possible
     changes in the design of Materials and may amend the specifications to
     comply with Corning's new requirements. If Seller has the technical
     capability to meet Corning's new requirements, Seller shall do so. Any
     price adjustments resulting from proposed design changes will be negotiated
     in godd faith by Seller and Corning.

17.  Patents. Seller agrees to indemnify, hold harmless and protect Corning
     against any costs (including reasonable attorneys' fees), liabilities, and
     judgments arising from any claim made by a third party against Corning that
     the materials supplied by Seller under this Agreement infringe patent or
     copyrights of such third party. Corning shall promptly notify Seller of any
     such claim, agrees to provide information and reasonable assistance, and
     give Seller sole authority to defend or settle such claim. Upon notice of
     an alleged infringement, Seller may, at its option and expense, (i) obtain
     for Coming the right to continue using the Materials, (ii) replace or
     modify the product so that is

<PAGE>   4

     becomes non-infringing or non-violating, (iii) substitute an equivalent
     non-infringing version of the Materials. In the event that none of the
     above options is reasonably available, either party may terminate this
     Agreement and Corning may return any and all Materials paid for and in
     Corning's inventory and obtain a refund from Seller of the price paid by
     Corning for such inventory. Termination hereunder does not discharge the
     obligations of Seller to defend Corning and pay costs or judgments.

     Notwithstanding the above provisions, Seller assumes no liability for any
     infringement claims based upon the use of the Materials either (i) in
     connection or in combination with equipment, devices, products or software
     not provided by Seller if such claims would not have resulted but for some
     combination or use, or (ii) for other than normal purposes.

     THE FOREGOING STATES EACH PARTY'S SOLE AND EXCLUSIVE REMEDY WITH RESPECT TO
     CLAIMS OF INFRINGEMENT OR VIOLATION OF THIRD PARTY PROPRIETARY RIGHTS OF
     ANY KIND.

18.  Excusable Failure or Delay (Force Majeure). Neither party shall be held
     responsible for the failure or delay in performance hereunder where such
     failure or delay is due to any act of God or of the public enemy, war,
     compliance with laws, governmental acts or regulations, fire, flood,
     epidemic, accident, unusually severe weather or other causes similar to the
     foregoing beyond their reasonable control. Any party whose performance is
     affected by such force majeure shall promptly give notice to the other
     party of the occurrence or circumstance upon which it intends to rely to
     excuse its performance. If the circumstances of force majeure affecting
     either party's performance hereunder delays performance for more than seven
     (7) days, then the other party may terminate this Agreement upon seven (7)
     days' advance written notice. In no event shall a failure or delay in
     performance attributable to the "Year 2000" or other computer system and/or
     software related malfunction be excusable under this paragraph or any other
     paragraph of this Agreement.

19.  [*]

20.  Price Protection. If Corning submits substantial evidence in writing that
     another producer of goods has lawfully offered Corning goods of similar
     quality, in similar quantities and under like terms and conditions, at a
     delivered cost at least [*] lower than the delivered cost hereunder, then
     Corning will give Seller written notice of such lower offer.

[*] Certain information on this page has been omitted and
    filed separately with the Commission. Confidential treatment
    has been requested with respect to the omitted portions.
<PAGE>   5

     If Seller does not agree, in writing and within thirty (30) days of such
     notice, to reduce its price immediately to meet that lower offer, then, at
     the expiration of that thirty (30) day period, Corning's only purchase
     obligation hereunder will be to purchase Materials for which releases have
     already been issued by Corning and accepted by Seller. Upon the purchase by
     Corning of the Materials under those prior releases, Corning will be deemed
     to have satisfied any and all purchase commitments and obligations
     hereunder, and will not be subject to any penalty, price adjustment or
     other liability for failure to purchase any additional Materials from
     Seller.

21.  No Assignment. This Agreement shall not be assigned and is not assignable
     or delegable by either party without the written consent of the other,
     which shall not be unreasonably withheld.

22.  Compliance with Laws. Seller shall comply with all applicable federal,
     state and local laws and regulations in the manufacture, processing, sale
     and transport of the Materials to be delivered hereunder. In the event that
     Seller's work does not comply with any such laws, codes, and regulations,
     Seller shall correct any such noncompliance at its sole expense and
     indemnify and hold Corning harmless from any claims, costs, fines,
     penalties, expenses, liabilities or losses on account of any such
     noncompliance.

23.  Default and Termination. This Agreement and all rights granted hereunder
     may be terminated by either party: (a) in the event of a continuing default
     by the other party of any obligation hereunder, effective seven Corning
     business (7) days after written notice of such default is given to the
     defaulting party; or (b) immediately in the event that either a delivery
     that is more than fifteen (15) Corning business days late, or if any three
     (3) deliveries are more than seven (7) Corning business days late in any
     six-month period; or (c) immediately upon written notice in the event of
     bankruptcy, insolvency or any other financial condition creating reasonable
     doubt as to that party's ability to perform hereunder. If any instance
     under (a) or (b) occur, Corning must notify Seller in writing within (30)
     days of each event. In the event that Corning does not notify Seller,
     termination rights for that event lapse.

     No such termination shall affect or discharge any obligations of either
     party which arose prior to the effective date of termination with respect
     to warranties, indemnification, moneys owed or confidential information.

24.  Cancellation for Buyer's Convenience. Corning may cancel a firm Purchase
     Order at any time prior to delivery. In the event of such cancellation,
     Seller shall immediately cease to incur expense against the affected
     Purchase Order.

     If the purchase order covered standard product which is easily sellable to
     Seller's other customers, the Corning will have no liability to Seller for
     cancellation of the Purchase Order.

     For Purchase Orders for nonstandard products, Corning's liability in the
     event of cancellation shall be limited to the following for deliveries
     cancelled under such Purchase Order:

<PAGE>   6

        a. Actual cost incurred by Seller, up to and including the date of
           cancellation for material costs and direct labor costs; and

        b. Reasonable costs that Seller has reasonably committed to pay to its
           suppliers; and for the materials for undelivered quantities.

     Seller shall use reasonable endeavors to mitigate the amount of such
     charges. Seller will provide Corning with clear documentation of all costs
     and charges which Corning is liable under this provision. In no event will
     Corning be liable for cancellation charges in excess of the contract value
     of the Materials cancelled. Upon payment of such cancellation charges by
     Corning, Seller shall deliver to Corning, in accordance with the delivery

        all taxes, customs, and freight.

2.2     Should the parties agree upon payment by installments which are due
        prior to final and complete performance of the entire development
        service, New Focus undertakes, prior to payment of the respective
        installment, to provide HP with an irrevocable, unconditional and
        absolute guarantee from a bank recognized as guarantor in the amount of
        the respective installment. HP shall return such guarantee to the
        supplier upon written confirmation of acceptance of the prototypes or
        the software.

        Installments by HP shall not include any acceptance of the prototypes,
        developed software or the production units. With payment of the

3.1     The prototypes as well as the software shall be manufactured by New
        Focus in accordance with the project schedule (Schedule 3) and the
        development phases contained therein as well as in Schedule 1.

3.2     Prior to the commencement of development, New Focus shall ensure that
        the specifications are complete and that implementation of the contents
        thereof is feasible. Should New Focus detect any defects or omissions
        upon examination of the specifications, it shall inform HP hereof in
        writing without any undue delay.


                                                                               2
<PAGE>   3
3.3     The deadlines outlined in the agreed project schedule (Schedule 3) shall
        be binding upon both parties.

3.3     In order to ensure successful and timely performance of the Development
        agreement for both parties, the parties hereto agree that New Focus
        shall submit to HP a written report detailing key aspects of the project
        at regular monthly intervals. Both parties shall have the option of
        requesting that the other party engage in discussions regarding the
        current stage of development, problems arising in connection therewith,
        matters pertaining to coordination etc.

        New Focus shall, in particular, advise HP of the following in this
        regard:

3.4.1   PROJECT STATUS

        Classification of the system components on which work was performed
        during the period under review. The stage of work carried out and of the
        semi-finished work, as well as a comparison of the target and actual
        situation if the project schedule and/or the specification requirements
        have not (yet) been complied with. Any deviations or postponement of
        deadlines must be justified and the supplier is further required to
        indicate the measures planned for re-establishing the target situation.

3.4.2   FORECAST

        New Focus shall advise HP of the work scheduled for the next period
        under review, also with a view to enabling HP to arrange, in good time,
        for any support which it may be required to provide.

        On HP's request, New Focus shall, during the course of discussions,
        provide HP with copies of HP-specific documentation regarding the
        development of prototypes and software available at the time of such
        discussions.

        Minutes, to be duly countersigned by both parties, shall be kept of all
        such discussions.

3.5     New Focus shall document the development result and the individual
        development steps and make such material available to HP in
        machine-readable form.

4.      RESOURCES

4.1     New Focus avails of a development center which is suitably equipped to
        develop the developed software defined under the subject-matter hereof.
        In the event HP employees are assigned to the development project New
        Focus shall provide appropriate support to these employees.

4.2     HP shall support New Focus as described in Schedule 5.



                                                                               3




<PAGE>   4
5.      MODIFICATIONS/AMENDMENTS TO THE SYSTEM DESCRIPTION/SPECIFICATIONS

5.1     Modifications to the specifications are subject to HP's prior written
        approval. HP may request that New Focus incorporate modifications or
        amendments. New Focus may also request that HP incorporate modifications
        or amendments. Any such  request must be submitted in writing. New Focus
        shall perform the modified services if and to the extent that New Focus
        can be reasonably expected to do so and New Focus has not provided HP
        with written justification as to why it cannot be reasonably expected to
        do so within 1 week of receipt for the modification request.

5.2     Should such modifications affect contractual agreements (relating to
        costs or performance deadlines for example), the parties hereto shall
        accordingly revise such agreements taking the increase/decrease in
        time/expenditure required into consideration. The modifications shall be
        performed within the framework of existing contractual agreements if no
        such demand for review is submitted to the other party to the agreement
        in writing within 2 weeks of receipt of the modification request by New
        Focus. HP undertakes to advise New Focus of the significance of its
        actions prior to commencement of the period in question.

5.3     In the event of a dispute regarding the scope of any increase/decrease
        in time/expenditure required on the basis of modifications, both
        parties hereto shall be entitled to request that an independent,
        publicly-appointed and certified expert decide the issue with binding
        effect for both parties.

5.4     New Focus shall inform HP immediately upon receipt of a modification
        request if work already carried out by New Focus would become unusable
        as a result of this modification.

6.      FAILURE TO ADHERE TO THE PROJECT SCHEDULE


6.1     If, during the development phases, it already becomes apparent that the
        completion date agreed upon in the project schedule (schedule 3) cannot
        be adhered to, New Focus shall advise HP hereof without delay indicating
        the reasons therefor. New Focus shall simultaneously advise HP of the
        period of delay by which the completion date is to be postponed
        vis-a-vis the deadline agreed upon in the project schedule.

6.2     If a deadline agreed upon in the project schedule is already or will
        apparently be exceeded by more than 2 weeks, HP may extend the deadline
        by a reasonable period of time. If this extended period expires to no
        avail, HP shall be entitled to rescind the agreement. This shall not
        apply if New Focus bears no responsibility for the existing or
        foreseeable failure to adhere to the project schedule or for the expiry
        to no avail of the period of grace.

6.3     Irrespective of the right to rescind the agreement pursuant to Article
        6.2 above, the following contractual penalty shall apply:


                                                                               4






<PAGE>   5
        Should New Focus be unable to adhere to the delivery deadlines agreed
        upon in the project schedule (Schedule 3) for the prototypes or the
        software during the respective development phases, HP shall be entitled,
        without providing any further evidence, to demand a contractual penalty
        in the amount of [*] of the net value of each development phase
        according to Schedule 1 for each working day beginning two weeks after
        the delivery deadlines of Schedule 3 or part thereof up to an amount
        not exceeding [*] of the total value of each development phase
        according to Schedule 1 however. This shall not apply if New Focus does
        not bear responsibility for the delay.


7.      EXAMINATION AND DELIVERY BY NEW FOCUS

7.1     Upon completion of development and manufacture of the prototypes
        together with the developed software in accordance with the
        specifications (Schedule 1), New Focus shall subject the prototypes and
        the software to a functional check pursuant to HP specifications in
        regard of the respective development phase according to Schedule 1 with
        a view to establishing conformity with the specifications. A test report
        shall be submitted.

7.2     New Focus shall deliver the tested prototypes and the developed software
        to HP on or before the deadline defined in the project schedule
        (Schedule 3). Tested means that no deviations from the specification
        requirements in regard of the respective development phase according to
        Schedule 1 and no other defects were detected during testing at New
        Focus.

        New Focus shall provide HP with all the necessary documentation/data
        sheets, source codes etc. upon delivery of the prototypes as described
        in Schedule 1.

7.3     New Focus shall produce further prototypes and production units in
        accordance with the terms and provisions hereof according to Schedule 1.


8.      EXAMINATION AND ACCEPTANCE BY HP

8.1     HP shall examine the design of the prototypes. HP shall accept the
        design provided that the prototypes to be manufactured in accordance
        with this design will ensure the fulfillment of the product
        specifications as described in Schedule 1.

8.2     HP shall subject any prototype as well as the developed software to a
        separate functional check within eight weeks of delivery, according to
        Schedule 1. HP shall provide weekly updates/reports on the progress
        and results of the testing. A test report shall be submitted.

8.3     HP shall submit a written acceptance certificate of the prototypes and
        the developed software to New Focus if the prototypes and the developed
        software conform to all of the specification requirements of Schedule 1
        and if no other defects can be detected.

                                                                               5

[*] Certain information on this page has been omitted and
    filed separately with the Commission. Confidential treatment
    has been requested with respect to the omitted portions.
<PAGE>   6
8.4     Should HP detect deviations from the specifications or defects during
        the course of the functional check, HP shall inform New Focus thereof in
        writing.

        In this event, New Focus shall provide HP with repaired or newly
        manufactured prototypes or developed software which is/are free of the
        respective defect(s) within five working days. New Focus shall ensure
        that the defects are remedied and rectified according to Schedule 4 by
        employees who were already involved in the development of the developed
        software defined under the subject-matter hereof. Subject to mutual
        agreement between the parties, such rectification of defects may be
        carried out by HP. In the case that New focus can not rectify such
        defects within short term New Focus shall provide HP a temporary
        solution.

8.5     Following delivery of the repaired / newly manufactured prototypes or
        developed software, HP shall conduct another functional test. If
        deviations from the specifications (Schedule 1) or defects are still
        detected in the repaired / newly manufactured prototypes or developed
        software and these are not remedied and rectified within 15 working
        days of receipt of appropriate notice thereof from HP, HP may, at its
        discretion, rescind the Agreement, rectify the defect itself or have it
        rectified by a third party at New Focus's expense. Any further claims
        shall remain unaffected thereby.

8.6     In the case that HP does not accept the manufactured prototypes or the
        developed software within a reasonable period of time after delivery,
        New Focus may set forth a deadline in order to declare the acceptance.
        The manufactured prototypes or the developed software shall deemed to
        be accepted if HP does neither declare the acceptance nor informs about
        defects. HP shall not refuse the acceptance because of insignificant
        defects. If HP accepts the manufactured prototypes or the developed
        software without regard of defects, these defects shall be written down
        within the minutes of the acceptance.

8.7     According to Schedule 1 HP shall release the prototypes for production
        and delivery of 30 production units to HP upon acceptance of the
        prototypes. In this case, the New Focus prices for these production
        units as set forth in Schedule 1 shall apply.

        HP shall be entitled to purchase additional production units and

SCHEDULE 1 - SPECIFICATIONS, DEVELOPMENT PHASES, PAYMENT

A.)  PRODUCT TO BE DEVELOPED:

1.   A 1550 nm tunable laser source module (entire plug-in module) which will be
     based on the patented (US Patent No. [*] and [*]) opto-mechanical design of
     the New Focus ECDL product family for integration into the HP optical
     component test platforms (or additional purposes).

2.   This includes the development and production of the opto-mechanical
     sub-assemblies as well as the assembly and test of the chassis and
     interface electronics. Specifically, New Focus will reduce the cost and
     size of the opto-mechanical head associated with the current New Focus
     products, develop the low cost electronics needed to interface the
     multimeter platform, and refine the packaging of the isolated fiber launch.
     In addition, New Focus will develop an operations approach that allows for
     the production of up to [*] plug-in modules per year. In the event that [*]
     plug-in modules per year are desired an option, which requires additional
     funding and a [*] period to increase capacity to [*] per year, may be
     exercised by HP. The additional funding for this option will be part of a
     separate development contract.

     A focused team operating in a project management infrastructure and
     reporting directly to the New Focus management team will be employed for
     that purpose.

                    30 Production Units                 $[*]
</TABLE>

    The development cost approach is to use non-recurring engineering funding
    from HP to develop the product and production line so that the per unit
    price in 3/98 will be $[*]. The per unit price will be $[*] and the
    development cost will be $[*] to get to [*] fully tested plug in modules
    per year. This $[*] non-recurring engineering effort will include delivery
    of [*] units but the [*] delivered at the end of the project will be $[*]
    each (FOB Santa Clara, CA). This $[*] per unit price is based on a cost for
    the coated diodes of $[*]. If a qualified source of AR coated diodes could
    be identified that would work in our cavity then the per unit price would be
    $[*] plus the cost (to NFI) of the diodes.

    An option to increase the capacity in a separate development contract has
    been offered, but not exercised by HP at this time, that will allow New
    Focus to tool up to the [*]/year numbers associated with the high end of the
    HP marketing numbers. This effort would be covered under a separate
    development project and New Focus would need [*] advance notice before the
    increased capacity could be realized. If this option is chosen the per unit
    price for a quantity of [*] units would be $[*] (FOB Santa Clara, CA) (New
    Focus are essentially only increasing capacity with this approach) and the
    per unit price at [*] units would be $[*] (FOB Santa Clara, CA). In these
    cases the assumed cost of the AR coated diode is $[*] and $[*],
    respectively.


B.) TECHNICAL APPROACH (PROPOSED BY NEW FOCUS):

1.    [*]
2.    [*]
3.    [*]
4.    [*]
5.    [*]
6.    [*]
7.    [*]

[*] Certain information on this page has been omitted and
    filed separately with the Commission. Confidential treatment
    has been requested with respect to the omitted portions.

                                                                              17
<PAGE>   18
The above Technical Approach is understood as a proposal by New Focus which may
be amended, provided that the development requirements as set out in this
Schedule 1 are fully met.

New Focus will use the HP communications and interface design, which uses a [*],
together with New Focus design for [*] to [*] a complete [*]. To do this New
Focus will acquire the [*] development environment necessary to design with this
processor, New Focus will use [*] and New Focus will work to ensure that there
is complete overlap between the development effort at [*] and at [*].

C.) OPERATIONS APPROACH (PROPOSED BY NEW FOCUS):

New Focus will develop a production line solely dedicated to the assembly and
test of the [*] in Santa Clara CA using some of New Focus' available
manufacturing space. The approach is summarized below:

1.    [*]
2.    [*]
3.    [*]
4.    [*]

New Focus will expand and improve its present [*] production line (model [*])
for use in the production of up to [*] per year.


D.) PROJECT MANAGEMENT BY NEW FOCUS:

This development effort will require a focused team operating within a tight
schedule. The scope of the project is well understood as are the resources
necessary to accomplish the task. New Focus will create a development team that
will report directly to the VP of Engineering. This team will be solely
dedicated to this project. The team will consist of but not be limited to:

1. Project Manager:                     Extensive experience with ECDL's,
                                        project management, and e-o-engineering

SCHEDULE 4 - BUGFIXING

1.   Any bugs in the developed software shall be recorded and verified by HP.
     Following verification, HP shall forward the bug report to New Focus.

     Bugs shall be categorized as follows:

     A.   Serious bugs

          Bugs that result in system crashes (hangs or halts), loss of data,
          destruction of data, corruption of data or cases of unreasonable
          handling effort for which no "workaround" is available (i.e. there is
          no method accepted by HP or by the customer for either avoiding the
          bug or using the developed software).

          Any medium bug as defined in B of this schedule 4 which causes a
          serious bug as defined above within the final optical component
          platforms shall additionally be categorized as a serious bug.

     B.   Medium bugs

          Bugs as specified under A above, but for which a "workaround" is
          available for bug avoidance.

     C.   Minor bugs

          Any bugs not included in categories A and B above.

2.   Any serious bugs in the developed software shall be immediately fixed by
     New Focus. New Focus will begin to fix the bug 24 hours after the
     respective report by HP the latest. New Focus shall fix the bug during 3
     days or during a longer period agreed by HP. If New Focus is unable to
     reproduce or to fix any bug immediately on its own computer system, it
     shall fix the bug - if decided by HP - on-site in customer's place.

3.   Any medium bug in the developed software shall be fixed in a reasonable
     period of time. New Focus shall begin fixing the bug during 48 hours after
     the respective report by HP. New Focus shall fix the bug during two weeks
     or during a longer period agreed by HP.

4.   Any other bugs shall be fixed as soon as possible within the scope of the
     maintenance of the developed software.

5.   New Focus shall update the documentation in accordance with the bug fix.


                                                                              20
<PAGE>   21


6.   New Focus shall ensure that any serious and medium bugs shall be fixed for
     both the current and the previous operating system release.

7.   New Focus will maintain a telephone number with a designated knowledgeable
     contact to HP to call during normal business hours to report problems and
     receive assistance.

8.   The Bugfixing according to this schedule 4 shall be free of charge during
     the warranty period.

<PAGE>   2
1.   If not expressly stated to the contrary herein, all provisions set forth
     in the Development Agreement of 23.12.1996 (the "Agreement") shall fully
     apply to this Addendum and shall remain in full force and effect.

2.   Delivery by New Focus of the [*] units as described in the Agreement shall
     be due on July 31, 1998. The per unit price for these production units
     shall remain unchanged at $[*].--([*] U.S. Dollars).

3.   The parties hereto will agree on separate terms and conditions for a
     contract regarding the production and delivery of the Tunable Laser Source
     Modules as defined in Clause 11.1 of the Agreement. In amendment of
     Schedule 1 A.) 5. of the Agreement, the parties agree on an initial per
     unit price ("HP Purchase Price") of $[*]. -- ([*] U.S. Dollars) for the
     Module. This HP Purchase Price is based on the initial HP U.S. List Price
     for the Module of $[*]. -- ([*] U.S. Dollars). To the extent HP decreases
     or increases the HP U.S. List Price for the Module, New Focus will decrease
     or increase the HP Purchase Price by half of the percentage the HP List
     Price decreased or increased. If and to the extent the HP Purchase Price
     falls below $[*],-- ([*] U.S. Dollars), New Focus shall have the right to
     terminate the contract regarding the production and delivery of the Tunable
     Laser Source Modules. If and to the extent the HP List Price falls below
     $[*] -- ([*] U.S. dollars), HP shall have the right to terminate such
     contract. These rights of termination shall be specified in detail in such
     contract. It is understood between the parties hereto that, in this case,
     HP shall be absolutely free to manufacture the Modules itself or have the
     Modules manufactured and delivered by a third party provided licensing
     agreements as outlined in Clause 7 of this Addendum are strictly adhered
     to. In addition, HP shall not be responsible for any additional development
     costs associated with supplying HP with the PMF Option of the Module due to
     the fact that such additional development costs were already covered by the
     NRE payments documented in the Development Contract of December 23, 1996.

4.   HP agrees to pay to New Focus an amount of $[*].--([*] U.S. Dollars) within
     30 days of the execution of this Addendum in order to ensure timely
     manufacturing and delivery of the Modules by New Focus. Payment shall be
     subject to New Focus providing HP a guarantee for [*]% ($[*].--[*] U.S.
     Dollars) of the above amount from an internationally recognized Bank
     substantially in the form as laid out in Schedule 1 hereto.

5.   New Focus shall repay up to [*]% ($[*].--[*] U.S. Dollars) of the above
     amount to the extent that one or more of the following applies:

     (i)  New Focus being in delay with any deadline set forth in the
          Agreement, this Addendum or the production and delivery contract;
          provided that a delay with respect to the delivery of the production
          units according to Clause 2 above shall


[*] Certain information on this page has been omitted and
    filed separately with the Commission. Confidential treatment
    has been requested with respect to the omitted portions.
                                                                               2
<PAGE>   3
          only trigger repayment if such delay exceeds one month and New Focus
          does not provide HP with reasonably sufficient justification for such
          delay

          and/or HP may not be reasonably expected to accept such delay and/or
          the delay has not been primarily caused by HP.

    (ii)  New Focus being in default of any other material provision of the
          Agreement, this Addendum or the production and delivery contract.

   The following repayment schedule shall be binding:

   $[*].--([*] U.S. Dollars) on [*], 1998
   $[*].--([*] U.S. Dollars) on [*], 1998
   $[*].--([*] U.S. Dollars) on [*], 1998
   $[*].--([*] U.S. Dollars) on [*], 1998
   $[*].--([*] U.S. Dollars) on [*], 1998

   Clauses 5 (i) and 5(ii) of this Addendum shall not apply for any failure or
   delay in the performance of New Focus due to causes including, but not
   limited to, an act of God, an act of civil or military authority, fire,
   epidemic, flood, earthquake, riot, war, sabotage, and governmental action
   which are beyond its reasonable control; provided that New Focus: (i)
   promptly gives HP written notice of such cause and, in any event, within
   fifteen (15) calendar days of discovery thereof; and (ii) uses diligent
   efforts to correct such failure or delay in its performance.

6. In view of HP's exclusive rights of use as described in Clause 11 of the
   Agreement, the Parties agree upon the following:

   (i)   New Focus may solely sell Modules in their completely assembled form
         (as defined by form factor, HW and SW interface) to HP.

   (ii)  Until HP officially informs New Focus of the obsolescence of the
         Module, New Focus shall not in any way manufacture and/or sell the
         Module and/or the building blocks (defined as the complete assembled
         opto-mechanical sub-assembly including but not limited to, the diode
         laser, external cavity, cavity optics, and drive train, in the exact
         configuration) thereof either under its own brand name in a way that
         direct competition to the HP Module is created or to direct HP Module
         competitors (including but not limited to corporations such as Anritsu,
         Photonetics, EXFO, Tektronix, Santec etc.) without the expressed
         written consent of HP.

   Subject to the foregoing, none of HP's rights according to Clause 11 of the
   Agreement and Clause 7 of this Addendum nor any other of HP's rights under
   the Agreement shall be in any way affected hereby.


[*] Certain information on this page has been omitted and

                                                                               3
<PAGE>   4
7.    With respect to HP's rights of use pursuant to 11.1 of the Agreement, and
      to the extent HP decides to manufacture the Modules itself or decides to
      have the Modules manufactured and delivered by a third party, the Parties
      shall enter into negotiations regarding the amount of the license fee for
      the New Focus patent in question (U.S. Patent No.: [*]). This license fee
      shall not exceed $[*]. -- ([*] U.S. Dollars) per manufactured Module. New
      Focus warrants that it is the sole owner of U.S. patent No. [*] and the
      therewith related applications [*] and [*] and any other patent or patent
      application claiming the priority of this patent or patent application.

      Furthermore, it is the understanding of the parties:

      (i) that no further royalty or license fees shall in any way be payable by
      HP to New Focus for the Module.

      (ii) that HP's use of the patent in question is limited to the Module in
      its completely assembled form (as defined by form factor, HW and SW
      interface).

8.    No ancillary verbal agreements have been made. Any alterations and
      amendments hereto must be made in writing in order to be valid and must
      expressly indicate that they constitute an alteration or amendment hereto.
      This shall similarly apply to any waiver of this written form requirement.

      Should one or more of the provisions hereof be or become void or invalid,
      the parties hereto undertake to replace such a provision with a valid
      provision which approximates the economic purpose or intent of the void or
      invalid provision as closely as possible. The validity of the remaining
      provisions shall remain unaffected thereby.

For HP:                                For New Focus:

        months window (further delivery milestones after March 2000 will be
        agreed to in a separate purchase agreement). The numbers of units
        delivered by New Focus will be reviewed on a monthly basis. If the total
        number for one month is below the numbers agreed to this respective
        month, New Focus will have a two months period to bring the total number
        of units back to the number agreed to for the respective three months
        period.

2.2.ii  In the event that New Focus fails to deliver the number of units agreed
        to for a three months period, AGILENT may terminate this Agreement upon
        90 days notice.

        AGILENT may also terminate this Addendum without notice if New Focus
        fails to deliver the first PM beta unit by February 29, 2000 or fails to

        AGILENT agrees to keep records showing the sales or other disposition of
        Monet Modules or other modules based on the optoblock defined in
        schedule 3 of this Addendum in sufficient detail to enable the royalties
        payable hereunder by AGILENT to be determined, and further agrees to
        permit its books and records to be examined to the extent necessary to
        verify the Royalties payable. Such examination to be made at the expense
        of New Focus by an independent auditor acceptable to AGILENT. Costs
        shall be born by AGILENT if discrepancies occur.

8. MISCELLANEOUS

8.1     With respect to section 8.5 of the Development Agreement of 23.12.1996,
        the liability for New Focus under this section, regarding AGILENT's
        right to rectify the defect itself or have it rectified by a third party
        at New Focus's expense, shall be limited to [*] U.S. dollars ($[*].)

8.2     Article 15.1 second paragraph of the Development Agreement of 23.12.1996
        shall be modified as follows:

        Good cause shall be deemed to exist, in particular, if one of the
        parties hereto fails to perform its contractual obligations, despite a
        reminder to this effect. Good cause shall also be deemed to exist for
        AGILENT if bankruptcy proceedings are instigated or initiated against
        New Focus's assets or in the event of a lasting modification to the
        ownership rights within New Focus (for example, if New Focus will be
        taken over by competitors within the market of telecommunication, test
        and measurement).

8.3     Article 15.1 third paragraph of the Development Agreement of 23.12.1996
        shall not apply to this Addendum.

8.4     No ancillary verbal agreements have been made. Any alterations and
        amendments hereto must be made in writing in order to be valid and must
        expressly indicate that they constitute an alteration or amendment
        hereto. This shall similarly apply to any waiver of this written form
        requirement.

8.5     Should one or more of the provisions hereof be or become void or
        invalid, the parties hereto undertake to replace such a provision with a
        valid provision which approximates the economic purpose or intent of the
        void or invalid provision as closely as possible. The validity of the
        remaining provisions shall remain unaffected thereby.

8.6     In the case that AGILENT transfers all or part of its assets to a new
        legal entity and therefore has to assign and/or transfer the rights and
        obligations under the agreement and this Addendum No 2 to such new legal
        entity, New Focus declares its agreement to such assignment or transfer
        and AGILENT accepts such agreement.

                Bugs that result in system crashes (hangs or halts), loss of
                data, destruction of data, corruption of data or cases of
                unreasonable handling effort for which no "workaround" is
                available (i.e. there is no method accepted by AGILENT or by the
                customer for either avoiding the bug or using the developed
                software).

                Any medium bug as defined in B. of this schedule 4 which causes
                a serious bug as defined above within the final optical
                component platforms shall additionally be categorized as a
                serious bug.

        B.      Medium bugs

                Bugs as specified under A above, but for which a "workaround" is
                available for bug avoidance.

        C.      Minor bugs

                Any bugs not included in categories A and B above.

2.      Any serious bugs in the developed software shall be immediately fixed by
        New Focus. New Focus will begin to fix the bug 24 hours after the
        respective report by AGILENT the latest. New Focus shall fix the bug
        during 3 days or during a longer period agreed by AGILENT. If New Focus
        is unable to reproduce or to fix any bug immediately on its own computer
        system, it shall fix the bug - if decided by AGILENT - on-site in
        customer's place.

3.      Any medium bug in the developed software shall be fixed in a reasonable
        period of time. New Focus shall begin fixing the bug during 48 hours
        after the respective report by AGILENT. New Focus shall fix the bug
        during two weeks or during a longer period agreed by AGILENT.

4.      Any other bugs shall be fixed as soon as possible within the scope of
        the maintenance of the developed software.

5.      New Focus shall update the documentation in accordance with the bug fix.


                                                                               8

                         LOAN AND SECURITY AGREEMENT
                                 (EQUIPMENT)


      The Borrower and Lender identified on the cover page of this document have
entered or anticipate entering into one or more transactions pursuant to which
Lender agrees to make available to Borrower an equipment loan facility governed
by the terms and conditions set forth in this document and one or more
Supplements executed by Borrower and Lender which incorporate this document by
reference. Each Supplement constitutes a supplement to and forms part of this
document, and will be read and construed as one with this document, so that
this document and the Supplement constitute a single agreement between the
parties (collectively referred to as this "Agreement").

      Accordingly, the parties agree as follows:

ARTICLE 1 - INTERPRETATION

      1.1   DEFINITIONS.  The terms defined in Article 10 and in the Supplement
will have the meanings therein specified for purposes of this Agreement.

      1.2   INCONSISTENCY.  In the event of any inconsistency between the
provisions of any Supplement and this document, the provisions of the
Supplement will be controlling for the purpose of all relevant transactions.

ARTICLE 2 - THE COMMITMENT AND LOANS

      2.1   THE COMMITMENT.  Subject to the terms and conditions of this
Agreement, Lender agrees to make term loans to Borrower from time to time from
the Closing Date and to, but not including, the Termination Date in an
aggregate principal amount not exceeding the Commitment, for the purpose of
financing the acquisition or carrying of certain Equipment. The Commitment is
not a revolving credit commitment, and Borrower does not have the right to
repay and reborrow hereunder. Each Loan requested by Borrower to be made on a
single Business Day shall be for a minimum principal amount set forth in the
Supplement, except to the extent the remaining Commitment is a lesser amount.

      2.2   NOTES EVIDENCING LOANS; REPAYMENT.  Each Loan shall be evidenced by
a separate Note payable to the order of Lender, in the total principal amount
of the Loan. Principal and interest of each Loan shall be payable at the times
and in the manner set forth in the Note.

      2.3   PROCEDURES FOR BORROWING.

            (a)  Borrower shall give Lender, at least five (5) Business Days'
prior to a proposed Borrowing Date, written notice of any request for borrowing
hereunder (a "Borrowing Request"). Each Borrowing Request shall be in
substantially the form of Exhibit "B" to the Supplement, shall be executed by
a responsible executive or financial officer of Borrower, and shall state how
much is requested, and shall be accompanied by such other information and
documentation as Lender may reasonably request.

            (b)  No later than 1:00 p.m. Pacific Standard Time on the Borrowing
Date, if Borrower has satisfied the conditions precedent in Article 4, Lender
shall make the Loan available to Borrower in immediately available funds.

      2.4   INTEREST.  Basic Interest on the outstanding principal balance of
the each Loan shall accrue daily at the Designated Rate from the Borrowing Date
until the Maturity Date.

      2.5   TERMINAL PAYMENT.  Borrower shall pay the Terminal Payment with
respect to each Loan on the Maturity Date of such Loan.

      2.6   INTEREST RATE CALCULATION.  Basic Interest, along with charges and
fees under this Agreement and any Loan Document, shall be calculated for actual
days elapsed on the basis of a 360-day year, which results in higher interest,
charge or fee payments than if a 365-day year were used. In no event shall
Borrower be obligated to pay Lender interest, charges or fees at a rate in
excess of the highest rate permitted by applicable law from time to time in
effect.

      2.7   DEFAULT INTEREST.  Any unpaid payments of principal or interest or
the Terminal Payment with respect to any Loan shall bear interest from their
respective maturities, whether scheduled or accelerated, at the Designated Rate
for such Loan plus five percent (5.00%) per annum, until paid in full, whether
before or


                                      1
<PAGE>   3
after judgment (the "Default Rate"), Borrower shall pay such interest on
demand.

     2.8  LATE CHARGES. If Borrower is late in making any payment of
principal or interest or Terminal Payment under this Agreement by more than
five (5) days, Borrower agrees to pay a late charge of five percent (5%) OF
the installment due, but not less than fifty dollars ($50.00) for any one
such delinquent payment. This late charge may be charged by Lender for the
purpose of defraying the expenses incidental to the handling of such
delinquent amounts. Borrower acknowledges that such late charge represents a
reasonable sum considering all of the circumstances existing on the date of
this Agreement and represents a fair and reasonable estimate of the costs
that will be sustained by Lender due to the failure of Borrower to make
timely payments. Borrower further agrees that proof of actual damages would
be costly and inconvenient. Such late charge shall be paid without prejudice
to the right of Lender to collect any other  amounts provided to be paid or
to declare a default under this Agreement or any of the other Loan Documents
or from exercising any other rights and remedies of Lender.

     2.9  LENDER'S RECORDS. Principal, Basic interest, Terminal Payments and
all other sums owed under any  Loan Document shall be evidenced by entries in
records maintained by Lender for such purpose. Each payment on and any other
credits with respect to principal, Basic Interest, Terminal Payments and all
other sums outstanding under any Loan Document shall be evidenced by entries in
such records. Absent manifest error, Lender's records shall be conclusive
evidence thereof.

     2.10 GRANT OF SECURITY INTERESTS. To secure the timely payment and
performance of all of Borrower's Obligations to Lender, Borrower hereby grants
to Lender continuing security interests in all of the Collateral.

ARTICLE 3 - REPRESENTATIONS AND WARRANTIES

validly existing in good standing under the laws of the jurisdiction of its
incorporation, and is duly qualified to conduct business and is in good
sanding in each other jurisdiction in which its business is conducted or its
properties are located, except where the failure to be so qualified would not
reasonably be expected to have a Material Adverse Effect.

     3.2  AUTHORIZATION, VALIDITY AND ENFORCEABILITY. The execution, delivery
and performance of all Loan Documents executed by Borrower are within
Borrower's powers, have been duly authorized, and are not in conflict with
Borrower's articles or certificate of incorporation or by-laws, or the terms
of any charter or other organizational document of Borrower, as amended from

licensing, permit and fictitious name requirements necessary to lawfully
conduct the business in which it is engaged, and to any sales, leases or the
furnishing of services by Borrower, including without limitation those

have a material Adverse Effect.

     3.4  NO CONFLICT. To its knowledge the execution, delivery, and
performance by Borrower of all Loan Documents are not in conflict with any law,
rule, regulation, order or directive, or any indenture, agreement, or
undertaking to which Borrower is a party or by which Borrower may be bound or
affected.

     3.5  NO LITIGATION, CLAIMS OR PROCEEDINGS. There is no litigation, tax
claim, proceeding or dispute pending, or, to the knowledge of Borrower,
threatened against or affecting Borrower or its property, which may have a
Material Adverse Effect.

which have been delivered to Lender fairly and accurately reflect Borrower's
financial condition as of the latest date of such financial statements; and,
since that date there has been no Material Adverse Change.

relationship with any other business entity.

    3.8   ENVIRONMENTAL MATTERS. Borrower has reviewed, or caused to be reviewed
on its behalf, all Environmental Laws applicable to its business operations and
materials handled therein, and as a result thereof has reasonably concluded

have a Material Adverse Effect on Borrower's operations, properties or
financial condition.

     3.9  NO EVENT OF DEFAULT. No Default or Event of Default currently exists.

     3.10 FULL DISCLOSURE. None of the representations or warranties made by

by or on behalf of Borrower to Lender prior to the Closing date), contains any
untrue statement of a material fact or omits any material fact required to be
stated therein or necessary to make the statements made therein, in light of
the circumstances under which they are made, not misleading as of the time when

any other Loan Document shall have occurred.

     (b)  Any representation or warranty made, or financial statement,
certificate or other document provided, by Borrower under any Loan Document
shall prove to have been false or misleading in any material respect when made
or deemed made herein.

     (c)  Borrower shall fail to pay its debts generally as they become due or
shall commence any Insolvency Proceeding with respect to itself; an involuntary
Insolvency Proceeding shall be filed against Borrower, or a custodian, receiver,
trustee, assignee for the benefit of creditors, or other similar official, shall
be appointed to take possession, custody or control of the properties of
Borrower, and such involuntary Insolvency Proceeding, petition or appointment is
acquiesced to by Borrower or is not dismissed within sixty (60) days; or the
dissolution or termination of the business of Borrower.

     (d)  Borrower shall be in default beyond any applicable period of grace or
cure under any other agreement involving the borrowing of money, the purchase
of property, the advance of credit or any other monetary liability of any kind
to Lender or to any Person, exceeding the Threshold Amount or aggregate
indebtedness exceeding the sum of One Hundred Thousand Dollars ($100,000),
which results in the acceleration of payment of such obligation in an amount in
excess of the Threshold Amount.

     (e)  Any governmental or regulatory authority shall take any judicial or
administrative action, or any defined benefit pension plan maintained by
Borrower shall have any unfunded liabilities, any of which, in the reasonable
judgment of Lender, might have a Material Adverse Effect.

     (f)  Except for a merger pursuant to Section 6.2, any sale, transfer or

Amount shall be entered against Borrower which remain unsatisfied, unvacated or
unstayed pending appeal for ten (10) or more days after entry thereof.

     (h)  Except as provided for in Section 6.2, any Person or two or more

     (i)  Borrower shall fail to perform or observe any covenant
contained in Article 6 of this Agreement.

     (j)  Borrower shall fail to perform or observe any covenant contained in
this Agreement or any other Loan Document (other than a covenant which is
dealt with specifically elsewhere in this Article 7) and the breach of such
covenant is not cured within 30 days after the sooner to occur of Borrower's
receipt of notice of such breach from Lender or the date on which such breach
first becomes known to any officer of Borrower, provided, however, that if such
breach is not capable of being cured within such 30-day period and Borrower



                                       8
<PAGE>   10
timely notifies Lender of such fact and Borrower diligently pursues such cure,
then the cure period shall be extended to the date requested by Borrower's
notice but in no event more than 90 days from the initial breach; provided,
further, that such additional 60-day opportunity to cure shall not apply in the
case of any failure to perform or observe any covenant which has been the
subject of a prior failure within the preceding 180 days or which is a willful
and knowing breach by Borrower.

     7.2 REMEDIES UPON DEFAULT. Upon the occurrence and during the continuance
of an Event of Default, Lender shall be entitled to, at its option, exercise any
or all of the rights and remedies available to a secured party under the Uniform
Commercial Code or any other applicable law, and exercise any or all of its
rights and remedies provided for in this Agreement and in any other Loan
Document. The obligations of Borrower under this Agreement shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any Obligations is rescinded or must otherwise be returned by Lender upon, on
account of, or in connection with, the insolvency, bankruptcy or reorganization
of Borrower or otherwise, all as though such payment had not been made.

     7.3 SALE OF COLLATERAL. Upon the occurrence and during the continuance of
an Event of Default, Lender may sell all or any part of the Collateral, at
public or private sales, to itself, a wholesaler, retailer or investor, for
cash, upon credit or for future delivery, and at such price or prices as Lender
may deem commercially reasonable. To the extent permitted by law, Borrower
hereby specifically waives all rights of redemption and any rights of stay or
appraisal which it has or may have under any applicable law in effect from time
to time. Any such public or private sales shall be held at such times and at
such place(s) as Lender may determine. In case of the sale of all or any part
of the Collateral on credit or for future delivery, the Collateral so sold may
be retained by Lender until the selling price is paid by the purchaser, but
Lender shall not incur any liability in case of the failure of such purchaser
to pay for the Collateral and, in case of any such failure, such Collateral may
be resold. Lender may, instead of exercising its power of sale, proceed to
enforce its security interest in the Collateral by seeking a judgment or decree
of a court of competent jurisdiction.

     7.4 BORROWER'S OBLIGATIONS UPON DEFAULT. Upon the request of Lender after
the occurrence and during the continuance of an event of Default, Borrower will:

     (a)  Assemble and make available to Lender the Collateral at such place(s)
as Lender shall reasonably designate, segregating all Collateral so that each
item is capable of identification; and

     (b) Subject to the rights of any lessor, permit Lender, by Lender's
officers, employees, agents and representatives, to enter any premises where
any Collateral is located, to take possession of the Collateral, to complete
the processing, manufacture or repair of any Collateral, and to remove the
Collateral, or to conduct any public or private sale of the Collateral, all
without any liability of Lender for rent or other compensation for the use of
Borrower's premises.

ARTICLE 8 - SPECIAL COLLATERAL PROVISIONS

     8.1 PERFORMANCE OF BORROWER'S OBLIGATIONS. Without having any obligation
to do so, upon reasonable prior notice to Borrower, Lender may perform or pay
any obligation which Borrower has agreed to perform or pay under this
Agreement, including, without limitation, the payment or discharge of taxes or
Liens levied or placed on or threatened against the collateral. In so
performing or paying, Lender shall determine the action to be taken and the
amount necessary to discharge such obligations. Borrower shall reimburse Lender
on demand for any amounts paid by Lender pursuant to this Section, which
amounts shall constitute Obligations secured by the Collateral and shall bear
interest from the date of demand at the Default Rate.

     8.2 POWER OF ATTORNEY. For the purpose of protecting and preserving the
Collateral and Lender's rights under this Agreement, Borrower hereby
irrevocably appoints Lender, with full power of substitution, as its
attorney-in-fact with full power and authority, after the occurrence and during
the continuance of an Event of Default, to do any act which Borrower is
obligated to do hereunder; to exercise such rights with respect to the
Collateral as Borrower might exercise; to use such Equipment, Fixtures or other
property as Borrower might use; to enter Borrower's premises; to give notice of
Lender's security interest in, and to collect the Collateral; and to execute
and file in Borrower's name any financing statements, amendments and
continuation statements necessary or desirable to perfect or continue the
perfection of


                                       9
<PAGE>   11
Lender's security interests in the Collateral. Borrower hereby ratifies all
that Lender shall lawfully do or cause to be done by virtue of this appointment.

     8.3  AUTHORIZATION FOR LENDER TO TAKE CERTAIN ACTION. The power of
attorney created in Section 8.2 is a power coupled with an interest and shall
be irrevocable. The powers conferred on Lender hereunder are solely to protect
its interests in the Collateral and shall not impose any duty upon Lender to
exercise such powers. Lender shall be accountable only for amounts that it
actually receives as a result of the exercise of such powers and in no event
shall Lender or any of its directors, officers, employees, agents or
representatives be responsible to Borrower for any act or failure to act,
except for gross negligence or willful misconduct. After the occurrence and
during the continuance of an Event of Default, Lender may exercise this power
of attorney without notice to or assent of Borrower, in the name of Borrower,
or in Lender's own name, from time to time in Lender's sole discretion and at
Borrower's expense, provided that such expenses are reasonable and actually
incurred. To further carry out the terms of this Agreement, after the
occurrence and during the continuance of an Event of Default, Lender may:

     (a)  Sign and endorse any invoice, freight or express bills, bills of
loading, storage or warehouse receipts; drafts, certificates and statements
under any commercial or standby letter of credit relating to Collateral; or any
other documents relating to the Collateral, including without limitation the
Records.

     (b)  Use or operate Collateral or any other property of Borrower for the
purpose of preserving or liquidating Collateral.

     (c)  File any claim or take any other action or proceeding in any court of
law or equity or as otherwise deemed appropriate by Lender for the purpose of
collecting any and all monies due or securing any performance to be rendered
with respect to the Collateral.

     (d)  Commence, prosecute or defend any suits, actions or proceedings or as
otherwise deemed appropriate by Lender for the purpose of protecting or
collecting the Collateral.

     (e)  Prepare, adjust, execute, deliver and receive payment under insurance
claims, and collect and receive payment of and endorse any instrument in
payment of loss or returned premiums or any other insurance refunds or return,
and apply such amounts at Lender's sole discretion toward repayment of the
Obligation or replacement of the Collateral.

     8.4  APPLICATION OF PROCEEDS. Any Proceeds and other monies or property
received by Lender pursuant to the terms of this Agreement or any Loan Document
may be applied by Lender first to the payment of expenses of collection,
including without limitation reasonable attorney's fees, and then to the
payment of the Obligations in such order of application as Lender may elect.

     8.5  DEFICIENCY. If the Proceeds of any disposition of the Collateral are
insufficient to cover all costs and expenses of such sale and the payment in
full of all the Obligations, plus all other sums required to be expended or
distributed by Lender, then Borrower shall be liable for any such deficiency.

     8.6  LENDER TRANSFER. Upon the transfer of all or any part of the
Obligations, Lender may transfer all or 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 Lender hereunder with respect to such Collateral so
transferred, but with respect to any Collateral not so transferred, Lender
shall retain all rights and powers hereby given.

     8.7  LENDER'S DUTIES.

     (a)  Lender shall use reasonable care in the custody and preservation of
any Collateral in its possession. Without limitation on other conduct which may
be considered the exercise of reasonable care, Lender shall be deemed to have
exercised reasonable care in the custody and preservation of such Collateral if
such Collateral is accorded treatment substantially equal to that which Lender
accords its own property, or taking any necessary steps to preserve any rights
against any Person with respect to any Collateral. Under no circumstances shall
Lender be responsible for any injury or loss to the Collateral, or any part
thereof, arising from any cause beyond the reasonable control of Lender.

     (b)  Neither Lender, nor any of its directors, officers, employees, agents,
attorneys or any other person affiliated with or representing Lender shall be
liable for any claims, demands, losses or damages, of



                                       10
<PAGE>   12
any kind whatsoever, made, claimed, incurred or suffered by Borrower or any
other party through the ordinary negligence of Lender, or any of its directors,
officers, employees, agents, attorneys or any other person affiliated with or
representing Lender.

      8.8 TERMINATION OF SECURITY INTERESTS. Upon the payment in full of the
Obligations and if Lender has no further obligations under its Commitment, the
security interest granted hereby shall terminate and all rights to the
Collateral shall revert to Borrower. Upon any such termination, the Lender
shall, at Borrower's expense, execute and deliver to Borrower such documents as
Borrower shall reasonably request to evidence such termination.

ARTICLE 9 - GENERAL PROVISIONS

      9.1 NOTICES. Any notice given by any party under any Loan Document shall
be in writing and personally delivered, sent by overnight courier, or United
States mail, postage prepaid, or sent by facsimile, or other authenticated
message, charges prepaid, to the other party's or parties' addresses shown on
the Supplement. Each party may change the address or facsimile number to which
notices, requests and other communications are to be sent by giving written
notice of such change to each other party. Notice given by hand delivery shall
be deemed received on the date delivered; if sent by overnight courier, on the
next business day after delivery to the courier service; if by first class
mail, on the third business day after deposit in the U.S. Mail; and if by
facsimile, on the date of transmission.

      9.2 BINDING EFFECT. The Loan Documents shall be binding upon and inure to
the benefit of Borrower and Lender and their respective successors and assigns;
provided, however, that Borrower may not assign or transfer Borrower's rights
or obligations under any Loan Document, except to a person or entity into which
it has merged or which has otherwise succeeded to all or substantially all of
its business and assets to which this Agreement pertains, by merger
reorganization or otherwise, in accordance with Section 6.2 without Lender's
prior written consent. Lender reserves the right to sell, assign, transfer,
negotiate or grant participations in all or any part of, or any interest in,
Lender's rights and obligations under the Loan Documents. In connection with
any of the foregoing, Lender may disclose all documents and information which
Lender now or hereafter may have relating to the Loans, Borrower, or its
business; provided that any person who receives such information shall have
agreed in writing in advance to maintain the confidentiality of such
information on terms reasonably acceptable to Borrower.

      9.3 NO WAIVER. Any waiver, consent or approval by Lender of any Event of
Default or breach of any provision, condition, or covenant of any Loan Document
must be in writing and shall be effective only to the extent set forth in
writing. No waiver of any breach or default shall be deemed a waiver of any
later breach or default of the same or any other provision of any Loan
Document. No failure or delay on the part of Lender in exercising any power,
right, or privilege under any Loan Document shall operate as a waiver thereof,
and no single or partial exercise of any such power, right, or privilege shall
preclude any further exercise thereof or the exercise of any other power, right
or privilege. Lender has the right at its sole option to continue to accept
interest and/or principal payments due under the Loan Documents after default,
and such acceptance shall not constitute a waiver of said default or an
extension of the Maturity Date unless Lender agrees otherwise in writing.

      9.4 RIGHTS CUMULATIVE. All rights and remedies existing under the Loan
Documents are cumulative to, and not exclusive of, any other rights or remedies
available under contract or applicable law.

      9.5 UNENFORCEABLE PROVISIONS. Any provision of any Loan Document executed
by Borrower which is prohibited or unenforceable in any jurisdiction, shall be
so only as to such jurisdiction and only to the extent of such prohibition or
unenforceability, but all the remaining provisions of any such Loan Document
shall remain valid and enforceable.

      9.6 ACCOUNTING TERMS. Except as otherwise provided in this Agreement,
accounting terms and financial covenants and information shall be determined
and prepared in accordance with GAAP.

      9.7 INDEMNIFICATION; EXCULPATION. Borrower shall pay and protect, defend
and indemnify Lender and Lender's employees, officers, directors, shareholders,
affiliates, correspondents, agents and representatives (other than Lender,
collectively "Agents") against, and hold Lender and each such Agent harmless
from, all claims, actions, proceedings, liabilities, damages, losses, expenses
(including, without limitation, attorneys' fees and costs) and other amounts
incurred by Lender and each such Agent, arising from (i) the


                                       11
<PAGE>   13
matters contemplated by this Agreement or any other Loan Documents or (ii) any
contention that Borrower has filed to comply with any law, rule, regulation,
order or directive applicable to Borrower's business; PROVIDED, HOWEVER, that
this indemnification shall not apply to any of the foregoing incurred solely as
the result of Lender's or any Agent's gross negligence or willful misconduct.
This indemnification shall survive the payment and satisfaction of all of
Borrower's Obligations to Lender.

     9.8  REIMBURSEMENT. Borrower shall reimburse Lender for all reasonable
costs and expenses actually incurred, including without limitation reasonable
attorneys' fees and disbursements expended or incurred by Lender in any
arbitration, mediation, judicial reference, legal action or otherwise in which
Lender obtains a favorable judgement, award or other similar favorable outcome
and in connection with (a) the preparation and negotiation of the Loan
Documents, (b) the amendment and enforcement of the Loan Documents, including
without limitation during any workout, attempted workout, and/or in connection
with the rendering or legal advice as to Lender's rights, remedies and
obligations under the loan Documents, (c) collecting any sum which becomes due
Lender under any Loan Document, (d) any proceeding for declaratory relief, any
counterclaim to any proceeding, or any appeal or (e) the protection,
preservation or enforcement of any rights of Lender. For the purposes of this
section, attorney's fees shall include, without limitation, fees incurred in
connection with the following; (1) contempt proceedings; (12) discovery; (3)
any motion, proceeding or other activity of any kind in connection with an
Insolvency Proceeding; (4) garnishment, levy, and debtor and third party
examinations; and (5) postjudgment motions and proceedings of any kind,
including without limitation any activity taken to collect or enforce any
judgment. All of the foregoing costs and expenses shall be payable upon demand
by Lender, and if not paid within forty-five (45) days of presentation of
invoices shall bear interest at the highest applicable Default Rate.

     9.9  EXECUTION IN COUNTERPARTS. This Agreement may be executed in any
number of counterparts which, when taken together, shall constitute but one
agreement.

     9.10  ENTIRE AGREEMENT. The Loan Documents are intended by the parties as
the final expression of their agreement and therefore contain the entire
agreement between the parties and supersede all prior understandings or
agreements concerning the subject matter hereof. This Agreement may be amended
only in a writing signed by Borrower and Lender.

LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR

                                       12
<PAGE>   14
LENDER EACH AGREES THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A
COURT TRIAL WITHOUT A JURY, WITHOUT LIMITING THE FOREGOING, THE PARTIES
FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY

                                                            San Jose, California


      The undersigned ("Borrower") promises to pay to the order of VENTURE
LENDING & LEASING II, INC., a Maryland corporation ("Lender") at its office at
2010 North First Street, Suite 310, San Jose, California 95131, or at such
other place as Lender may designate in writing, in lawful money of the United
States of America, the principal sum of _____________________ Dollars ($______),
with Basic Interest thereon from the date until maturity, whether scheduled or
accelerated, at a fixed rate per annum of eight and 40/100 percent (8.40%), and
a Terminal Payment in the sum of [10% of face amount] Dollars ($_______)
payable on the Maturity Date.

      This Note is one of the Notes referred to in, and is entitled to all the
benefits of, a Loan and Security Agreement dated [Agreement Date], between
Borrower and Lender (the "Loan Agreement"). Each capitalized term not otherwise
defined herein shall have the meaning set forth in the Loan Agreement. The Loan
Agreement contains provisions for the acceleration of the maturity of this Note
upon the happening of certain stated events.

      Principal of and interest on this Note shall be payable as follows:

      On the Borrowing Date, Borrower shall pay (i) Basic Interest, in advance,
on the outstanding principal balance of this Note at the Designated Rate for
the period from the Borrowing Date through [THE LAST DAY OF THE SAME MONTH];
and (ii) a first (1st) amortization installment of principal and Basic Interest
in the amount of _______________, in advance for the month of [first full month
after Borrowing Date] and (iii) a 36th [last] amortization installment of
principal and Basic Interest in the amount of $________________, in advance for
the month [date of last regular amortization payment].

      Commencing of the first day of the second full month after the Borrowing
Date, and continuing on the first day of each consecutive month thereafter,
principal and Basic Interest shall be payable, in advance, in [thirty-three
(33) equal consecutive installments of ___________________ Dollars ($________)
each, with a [thirty-fourth (34th)] installment equal to the entire unpaid
principal balance and accrued Basic Interest on ___________, 2000_. The
Terminal Payment amount shall be payable on [ONE MONTH LATER], 200_.

      Any unpaid payments of principal or interest on this Note shall bear
interest from their respective maturities, whether scheduled or accelerated, at
a rate per annum equal to the Default Rate. Borrower shall pay such interest on
demand.

      Interest, charges and fees shall be calculated for actual days elapsed on
the basis of a 360-day year, which results in higher interest, charge or fee
payments than if a 365-day year were used. In no event shall Borrower be
obligated to pay interest, charges or fees at a rate in excess of the highest
rate permitted by applicable law from time to time in effect.

      If Borrower is late in making any payment under this Note by more than
five (5) days, Borrower agrees to pay a "late charge" of five percent (5%) of
the installment due, but not less than fifty dollars ($50.00) for any one such
delinquent payment. This late charge may be charged by Lender for the purpose
of defraying the expenses


<PAGE>   21
incidental to the handling of such delinquent amounts. Borrower acknowledges
that such late charge represents a reasonable sum considering all of the
circumstances existing on the date of this Note and represents a fair and
reasonable estimate of the costs that will be sustained by Lender due to the
failure of Borrower to make timely payments. Borrower further agrees that proof
of actual damages would be costly and inconvenient. Such late charge shall be
paid without prejudice to the right of Lender to collect any other amounts
provided to be paid or to declare a default under this Note or any of the other
Loan Documents or from exercising any other rights and remedies of Lender.

     This Note shall be governed by, and construed in accordance with, the laws
of the State of California.

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED
OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH
ACT COVERING SUCH SECURITIES, THE TRANSFER IS MADE IN COMPLIANCE WITH RULE 144
PROMULGATED UNDER SUCH ACT OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR
THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE COMPANY, STATING
THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE
REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

                              WARRANT TO PURCHASE

                  35,000 SHARES OF SERIES D PREFERRED STOCK OF

                                NEW FOCUS, INC.

                         (Void after December 31, 2004)

This certifies that VENTURE LENDING & LEASING II, INC., a Maryland corporation,
or assigns (the "Holder"), for value received, is entitled to purchase from NEW
FOCUS, INC., a California corporation (the "Company"), 35,000 fully paid and
nonassessable shares of the Company's Series D Preferred Stock ("Preferred
Stock") for cash at a price of $4.00 per share (the "Stock Purchase Price") at
any time or from time to time up to and including 5:00 p.m. (Pacific time) on
December 31, 2004 (the "Expiration Date"), upon surrender to the Company at its
principal office at 2630 Walsh Avenue, Santa Clara, CA 95051-0905, (or at such
other location as the Company may advise Holder in writing) of this Warrant
properly endorsed with the Form of Subscription attached hereto duly filled in
and signed and upon payment in cash or by check of the aggregate Stock Purchase
Price for the number of shares for which this Warrant is being exercised
determined in accordance with the provisions hereof. The Stock Purchase Price
and the number of shares purchasable hereunder are subject to adjustment as
provided in Section 4 of this Warrant.

This Warrant is subject to the following terms and conditions:

     1.   Exercise; Issuance of Certificates; Payments for Shares.

          (a)  Unless an election is made pursuant to clause (b) of this
Section 1, this Warrant shall be exercisable at the option of the Holder, at
any time or from time to time, on or before the Expiration Date for all or any
portion of the shares of Preferred Stock (but not for a fraction of a share)
which may be purchased hereunder for the Stock Purchase Price multiplied by the
number of shares to be purchased. In the event, however, that pursuant to the
Company's Articles of Incorporation, as amended, an event causing automatic
conversion of the Company's Preferred Stock shall have occurred prior to the
exercise of this Warrant, in whole or in part, then this Warrant shall be
exercisable for the number of shares of Common Stock of the Company into which
the Preferred Stock not purchased upon any prior exercise of the Warrant would
have been so converted (and, where the context requires, reference to
"Preferred Stock" shall be deemed to include such Common Stock). The Company
agrees that the shares of Preferred Stock purchased under this Warrant shall be
and are deemed to be issued to the holder hereof as the record owner of such
shares as of the close of business on the date on which the form of
subscription shall have been delivered and payment made for such shares.
Subject to the provisions of Section 2, certificates for the shares of
Preferred Stock so purchased, together with any other securities or property to
which the Holder hereof is entitled upon such exercise, shall be delivered to
the Holder hereof by the Company at the Company's expense within a reasonable
time after the rights represented by this Warrant have been so exercised.
Except as provided in clause (b) of this Section 1, in case of a purchase of
less than all the shares which may be purchased under this Warrant, the Company
shall cancel this Warrant and execute and deliver a new Warrant or Warrants of
like tenor for the balance of the shares purchasable under the Warrant
surrendered upon such purchase to the Holder hereof within a reasonable time.
Each stock certificate so delivered shall be in such denominations of

<PAGE>   25
Preferred Stock as may be requested by the Holder hereof and shall be
registered in the name of such Holder or such other name as shall be designated
by such Holder, subject to the limitations contained in Section 2.

            (b)   The Holder, in lieu of exercising this Warrant by the
payment of the Stock Purchase Price pursuant to clause (a) of this Section 1,
may elect, at any time on or before the Expiration Date, to receive that
number of shares of Preferred Stock equal to the quotient of: (i) the
difference between (A) the Per Share Price (as hereinafter defined) of the
Preferred Stock, less (B) the Stock Purchase Price then in effect, multiplied
by the number of shares of Preferred Stock the Holder would otherwise have
been entitled to purchase hereunder pursuant to clause (a) of this Section 1
(or such lesser number of shares as the Holder may designate in the case of a
partial exercise of this Warrant); over (ii) the Per Share Price. Election to
exercise under this section (b) may be made by delivering a signed form of
subscription to the Company via facsimile, to be followed by delivery of the
warrant.

            (c)   For purposes of clause (b) of this Section 1, "Per Share
Price" means the product of: (i) the greater of (A) the closing price of the
Company's Common Stock as quoted by NASDAQ or listed on any exchange,
whichever is applicable, as published in the Western Edition of the Wall
Street Journal for the trading day immediately prior to the date of the
Holder's election hereunder or, (B) if applicable at the time of or in
connection with the exercise under clause (b) of this Section 1, the gross
sales price of one share of the Company's Common Stock pursuant to a
registered public offering or that amount which shareholders of the Company
will receive for each share of Common Stock pursuant to a merger,
reorganization or sale of assets; and (ii) that number of shares of Common
Stock into which each share of Preferred Stock is convertible. If the
Company's Common Stock is not quoted by NASDAQ or listed on an exchange, the
Per Share Price of the Preferred Stock (or the equivalent number of shares of
Common Stock into which such Preferred Stock is convertible) shall be the
price per share which the Company would obtain from a willing buyer for
shares sold by the Company from authorized but unissued shares as such price
shall be agreed upon by the Holder and the Company or, if agreement cannot be
reached within ten (10) business days of the Holder's election hereunder, as
such price shall be determined by a panel of three (3) appraisers, one (1) to
be chosen by the Company, one (1) to be chosen by the Holder and the third to
be chosen by the first two (2) appraisers. If the appraisers cannot reach
agreement within 30 days of the Holder's election hereunder, then each
appraiser shall deliver its appraisal and the appraisal which is neither the
highest nor the lowest shall constitute the Per Share Price. In the event
either party fails to choose an appraiser within 30 days of the Holder's
election hereunder, then the appraisal of the sole appraiser shall constitute
the Per Share Price. Each party shall bear the cost of the appraiser selected
by such party and the cost of the third appraiser shall be borne one-half by
each party. In the event either party fails to choose an appraiser, the cost
of the sole appraiser shall be borne one-half by each party.

      2.    Limitation on Transfer.

            (a)   The Warrant and the Preferred Stock shall not be transferable
except upon the conditions specified in this Section 2, which conditions are
intended to insure compliance with the provisions of the Securities Act of
1933, as amended (the "Securities Act"). Each holder of this Warrant or the
Preferred Stock issuable hereunder will cause any proposed transferee of the
Warrant or Preferred Stock to agree to take and hold such securities subject to
the provisions and upon the conditions specified in this Section 2.

            (b)   Each certificate representing (i) this Warrant, (ii) the
Preferred Stock, (iii) shares of the Company's Common Stock issued upon
conversion of the Preferred Stock and (iv) any other securities issued in
respect to the Preferred Stock or Common Stock issued upon conversion of the
Preferred Stock upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall (unless otherwise permitted by the
provisions of this Section 2 or unless such securities have been registered
under the Securities Act or sold under Rule 144) be stamped or otherwise
imprinted with a legend substantially in the following form (in addition to any
legend required under applicable state securities laws):

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED
OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH
ACT COVERING SUCH SECURITIES, THE TRANSFER IS MADE IN COMPLIANCE WITH RULE 144

<PAGE>   26
THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE COMPANY, STATING
THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE
REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

          (c)  The Holder of this Warrant and each person to whom this Warrant
is subsequently transferred represents and warrants to the Company (by
acceptance of such transfer) that it will not transfer the Warrant (or
securities issuable upon exercise hereof unless a registration statement under
the Securities Act was in effect with respect to such securities at the time of
issuance thereof) except pursuant to (i) an effective registration statement
under the Securities Act, (ii) Rule 144 under the Securities Act (or any other
rule under the Securities Act relating to the disposition of securities), or
(iii) an opinion of counsel, reasonably satisfactory to counsel for the
Company, that an exemption from such registration is available.

     3.   Shares to be Fully Paid; Reservation of Shares. The Company covenants
and agrees that all shares of Preferred Stock which may be issued upon the
exercise of the rights represented by this Warrant will, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable and free from all
preemptive rights of any shareholder and free of all taxes, liens and charges
with respect to the issue thereof (other than taxes in respect of transfer
occurring contemporaneously or as otherwise specified herein). The Company
further covenants and agrees that during the period within which the rights
represented by this Warrant may be exercised, the Company will at all times
have authorized and reserved, for the purpose of issue or transfer upon
exercise of the subscription rights evidenced by this Warrant, a sufficient
number of share of authorized but unissued Preferred Stock, or other securities
and property, when and as required to provide for the exercise of the rights
represented by this Warrant. The Company will take all such action as may be
necessary to assure that such shares of Preferred Stock may be issued as
provided herein without violation of any applicable law or regulation, or of
any requirements of any domestic securities exchange upon which the Preferred
Stock may be listed. The Company will not take any action which would result in
any adjustment of the Stock Purchase Price (as defined in Section 4 hereof) (i)
if the total number of shares of Preferred Stock issuable after such action
upon exercise of all outstanding warrants, together with all shares of Preferred
Stock then outstanding and all shares of Preferred Stock then issuable upon
exercise of all options and upon the conversion of all convertible securities
then outstanding, would exceed the total number of shares of Preferred Stock
then authorized by the Company's Articles of Incorporation, or (ii) if the
total number of shares of Common Stock issuable after such action upon the
conversion of all such shares of Preferred Stock together with all shares of
Common Stock then outstanding and then issuable upon exercise of all options
and upon the conversion of all convertible securities then outstanding would
exceed the total number of shares of Common Stock then authorized by the
Company's Articles of Incorporation.

     4.   Adjustment of Stock Purchase Price Number of Shares. The Stock
Purchase Price and the number of shares purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 4. Upon each adjustment of the Stock
Purchase Price, the Holder of this Warrant shall thereafter be entitled to
purchase, at the Stock Purchase Price resulting from such adjustment, the
number of shares obtained by multiplying the Stock Purchase Price in effect
immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment, and dividing the product
thereof by the Stock Purchase Price resulting from such adjustment.

          4.1  Subdivision or Combination of Stock. In case the Company shall
at any time subdivide its outstanding shares of Preferred Stock into a greater
number of shares, the Stock Purchase Price in effect immediately prior to such
subdivision shall be proportionately reduced, and conversely, in case the
outstanding shares of Preferred Stock of the Company shall be combined into a
smaller number of shares, the Stock Purchase Price in effect immediately prior
to such combination shall be proportionately increased.

          4.2  Dividends in Preferred Stock, Other Stock, Property,
Reclassification. If at any time or from time to time the holders of Preferred
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to
receive, without payment therefor,

               (a)  Preferred Stock, or any shares of stock or other securities
whether or not such securities are at any time directly or indirectly
convertible into or exchangeable for Preferred Stock, or any rights or


                                       3
<PAGE>   27
options to subscribe for, purchase or otherwise acquire any of the foregoing by
way of dividend or other distribution, or

          (b)  any cash paid or payable otherwise than as a cash dividend, or

          (c)  Preferred Stock or other or additional stock or other securities
or property (including cash) by way of spinoff, split-up, reclassification,
combination of shares or similar corporate rearrangement, (other than shares of
Preferred Stock issued as a stock split, adjustments in respect of which shall
be covered by the terms of Section 4.1 above).

Then and in each such case, the Holder hereof shall, upon the exercise of this
Warrant, be entitled to receive, in addition to the number of shares of
Preferred Stock receivable thereupon, and without payment of any additional
consideration therefore, the amount of stock and other securities and property
(including cash in the cases referred to in clauses (b) and (c) above) which
such Holder would hold on the date of such exercise had he been the holder of
record of such Preferred Stock as of the date on which holders of Preferred
Stock received or became entitled to receive such shares and/or all other
additional stock and other securities and property.

     4.3  Reorganization, Reclassification, Consolidation, Merger or Sale. If
any capital reorganization of the capital stock of the Company, or any
consolidation or merger of the Company with another corporation, or the sale of
all or substantially all of its assets to another corporation shall be effected
in such a way that holders of Preferred Stock shall be entitled to receive
stock, securities or assets with respect to or in exchange for Preferred Stock
(Corporate Event), then, as a condition of such reorganization,
reclassification, consolidation, merger or sale, lawful and adequate provision
shall be made whereby the holder hereof shall thereafter have the right to
purchase and receive (in lieu of the shares of the Preferred Stock of the
Company immediately theretofore purchasable and receivable upon the exercise of
the rights represented hereby) such shares of stock, securities or assets as may
be issued or payable with respect to or in exchange for a number of outstanding
shares of such Preferred Stock equal to the number of shares of such stock
immediately theretofore purchasable and receivable upon the exercise of the
rights represented hereby, provided, however, in the event that 1) the effective
price of such Corporate Event is in excess of the exercise price hereof
effective at the time of the Corporate Event, 2) the consideration received in
such Corporate Event is cash or shares that are of a publicly traded company
listed on a national market or exchange, without restrictions within 90 days of
the close of such Corporate Event, except for those of Rule 144 or 145, and 3)
the Company's shareholders own less than 50% of the voting securities of the
surviving entity, then this Warrant shall be deemed exercised in accordance with
the provisions of section 1(b) upon the closing of the Corporate Event. In any
such case, appropriate provision shall be made with respect to the rights and
interests of the holder of this Warrant to the end that the provisions hereof
(including, without limitation, provisions for adjustments of the Stock Purchase
Price and of the number of shares purchasable and receivable upon the exercise
of this Warrant) shall thereafter be applicable, as nearly as may be possible,
in relation to any share of stock, securities or assets thereafter deliverable
upon the exercise hereof.

     4.4  Sale or Issuance Below Purchase Price. If the Company shall at any
time or from time to time issue or sell any of its Common Stock, Preferred
Stock, options to acquire (or rights to acquire such options), or any other
securities convertible into or exercisable for Common Stock, for a
consideration per share less than the Stock Purchase Price in effect
immediately prior to the time of such issue or sale, the Conversion ratio shall
be adjusted in accordance with the Company's Articles of Incorporation.

     4.5  Notice of Adjustment. Upon any adjustment of the Stock Purchase
Price, and/or any increase or decrease in the number of shares purchasable upon
the exercise of this Warrant the Company shall give written notice thereof, by
first class mail, postage prepaid, addressed to the registered holder of this
Warrant at the address of such holder as shown on the books of the Company. The
notice, which may be substantially in the form of Exhibit "A" attached hereto,
shall be signed by the Company's chief financial officer and shall state the
Stock Purchase Price resulting from such adjustment and the increase or
decrease, if any, in the number of shares purchasable at such price upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation and the facts upon which calculation is based.


                                       4
<PAGE>   28
          4.6  Other Notices. If at any time:

               (a)  the Company shall declare any cash dividend upon its
Preferred Stock;

               (b)  the Company shall declare any dividend upon its Preferred
Stock payable in stock or make any special dividend or other distribution to
the holders of its Preferred Stock;

               (c)  the Company shall offer for subscription pro rata to the
holders of its Preferred Stock any additional shares of stock of any class or
other rights;

               (d)  there shall be any capital reorganization or
reclassification of the capital stock of the Company, or consolidation or
merger of the Company with, or sale of all or substantially all of its assets
to, another corporation;

               (e)  there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company; or

               (f)  the Company shall take or propose to take any other action,
notice of which is actually provided to holders of the Preferred Stock;

then, in any one or more of said cases, the Company shall give, by first class
mail, postage prepaid, addressed to the holder of this Warrant at the address of
such holder as shown on the books of the Company, (i) at least 20 day's prior
written notice of the date on which the books of the Company shall close or a
record shall be taken for such dividend, distribution or subscription rights or
for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, or other action and (ii) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, or other action, at least 20 day's written notice of the date when
the same shall take place. Any notice given in accordance with the foregoing
clause (i) shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Preferred Stock shall be
entitled thereto. Any notice given in accordance with the foregoing clause (ii)
shall also specify the date on which the holders of Preferred Stock shall be
entitled to exchange their Preferred Stock for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding-up, or other action as the case may
be.

          4.7  Certain Events. If any change in the outstanding Preferred Stock
of the Company or any other event occurs as to which the other provisions of
this Section 4 are not strictly applicable or if strictly applicable would not
fairly protect the purchase rights of the Holder of the Warrant in accordance
with the essential intent and principles of such provisions, then the Board of
Directors of the Company shall make an adjustment in the number and class of
shares available under the Warrant, the Stock Purchase Price and/or the
application of such provisions, in accordance with such essential intent and
principles, so as to protect such purchase rights as aforesaid. The adjustment
shall be such as will give the Holder of the Warrant upon exercise for the same
aggregate Stock Purchase Price the total number, class and kind of shares as he
would have owned had the Warrant been exercised prior to the event and had he
continued to hold such shares until after the event requiring adjustment.

     5.   Issue Tax. The issuance of certificates for shares of Preferred Stock
upon the exercise of the Warrant shall be made without charge to the Holder of
the Warrant for any issue tax in respect thereof; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Holder of the Warrant being exercised.

     6.   Closing of Books. Provided that the Holder shall be in compliance
with the terms of this Agreement, including but not limited to, Section 2, the
Company will at no time close its transfer books against the transfer of any
Warrant or of any shares of Preferred Stock issued or issuable upon the
exercise of any warrant.

<PAGE>   29
     7.   No Voting or Dividend Rights; Limitation of Liability. Nothing
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent as a shareholder in respect of meetings
of shareholders for the election of directors of the Company or any other
matters or any rights whatsoever as a shareholder of the Company. No dividends
or interest shall be payable or accrued in respect of this Warrant or the
interest represented hereby or the shares purchasable hereunder until, and only
to the extent that, this Warrant shall have been exercised. No provisions
hereof, in the absence of affirmative action by the holder to purchase shares
of Preferred Stock, and no mere enumeration herein of the rights or privileges
of the Holder hereof, shall give rise to any liability of such Holder for the
Stock Purchase Price or as a shareholder of the Company, whether such liability
is asserted by the Company or by its creditors.

     8.   Intentionally Omitted.

     9.   Registration Rights.  The Holder hereof shall be entitled, with
respect to the shares of Preferred Stock issued upon exercise hereof or the
shares of Common Stock or other securities issued upon conversion of such
Preferred Stock as the case may be, to, and bound by, all of the registration
rights and obligations set forth in the First Amended and Restated Registration
Rights Agreement dated as of July 31, 1998 to the same extent and on the same
terms and conditions as possessed by the Investors thereunder. The Company
shall take such action as may be reasonably necessary to assure that the
granting of such registration rights to the Holder does not violate the
provisions of such agreement or any of the Company's charter documents or rights
of prior Grantees of registration rights.

     10.  Rights and Obligations Survive Exercise of Warrant. The rights and
obligations of the Company, of the Holder of this Warrant and of the holder of
shares of Preferred Stock issued upon exercise of this Warrant, contained in
Sections 6 and 9 shall survive the exercise of this Warrant.

     11.  Modification and Waiver. This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

     12.  Notices. Any notice, request or other document required or
permitted to be given or delivered to the holder hereof or the Company shall be
deemed to have been given (i) upon receipt if delivered personally or by
courier (ii) upon confirmation of receipt if by telecopy or (iii) three business
days after deposit in the US mail, with postage prepaid and certified or
registered, to each such holder at its address as shown on the books of the
Company or to the Company at the address indicated therefor in the first
paragraph of this Warrant.

     13.  Binding Effect on Successors. This Warrant shall be binding upon any
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets. All of the obligations of the
Company relating to the Preferred Stock issuable upon the exercise of this
Warrant shall survive the exercise and termination of this Warrant. All of the
covenants and agreements of the Company shall inure to the benefit of the
successors or assign of the holder hereof. The Company will, at the time of the
exercise of this Warrant, in whole or in part, upon request of the Holder
hereof but at the Company's expense, acknowledge in writing its continuing
obligation to the Holder hereof in respect of any rights (including, without
limitation, any right to registration of the shares of Common Stock) to which
the holder hereof shall continue to be entitled after such exercise in
accordance with this Warrant; provided, that the failure of the holder hereof
to make any such request shall not affect the continuing obligation of the
Company to the Holder hereof in respect to such rights.

     14.  Descriptive Headings and Governing Law. The descriptive headings of
the several sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. This Warrant
shall be construed and enforced in accordance with, and the rights of the
parties shall be governed by, the laws of the State of California.

                              WARRANT TO PURCHASE

                  35,000 SHARES OF SERIES D PREFERRED STOCK OF

                                NEW FOCUS, INC.

                         (Void after December 31, 2004)


This certifies that VENTURE LENDING & LEASING II, INC., a Maryland corporation,
or assigns (the "Holder"), for value received, is entitled to purchase from NEW
FOCUS, INC., a California corporation (the "Company"), 35,000 fully paid and
nonassessable shares of the Company's Series D Preferred Stock ("Preferred
Stock") for cash at a price of $4.00 per share (the "Stock Purchase Price") at
any time or from time to time up to and including 5:00 p.m. (Pacific time) on
December 31, 2004 (the "Expiration Date"), upon surrender to the Company at its
principal office at 2630 Walsh Avenue, Santa Clara, CA 95051-0905, (or at such
other location as the Company may advise Holder in writing) of this Warrant
properly endorsed with the Form of Subscription attached hereto duly filled in
and signed and upon payment in cash or by check of the aggregate Stock Purchase
Price for the number of shares for which this Warrant is being exercised
determined in accordance with the provisions hereof. The Stock Purchase Price
and the number of shares purchasable hereunder are subject to adjustment as
provided in Section 4 of this Warrant.

This Warrant is subject to the following terms and conditions:

      1.        Exercise; Issuance of Certificates; Payment for Shares.

                (a)       Unless an election is made pursuant to clause (b) of
this Section 1, this Warrant shall be exercisable at the option of the Holder,
at any time or from time to time, on or before the Expiration Date for all or
any portion of the shares of Preferred Stock (but not for a fraction of a
share) which may be purchased hereunder for the Stock Purchase Price multiplied
by the number of shares to be purchased. In the event, however, that pursuant
to the Company's Articles of Incorporation, as amended, an event causing
automatic conversion of the Company's Preferred Stock shall have occurred prior
to the exercise of this Warrant, in whole or in part, then this Warrant shall
be exercisable for the number of shares of Common Stock of the Company into
which the Preferred Stock not purchased upon any prior exercise of the Warrant
would have been so converted (and, where the context requires, reference to
"Preferred Stock" shall be deemed to include such Common Stock). The Company
agrees that the shares of Preferred Stock purchased under this Warrant shall be
and are deemed to be issued to the holder hereof as the record owner of such
shares as of the close of business on the date on which the form of
subscription shall have been delivered and payment made for such shares.
Subject to the provisions of Section 2, certificates for the shares of
Preferred Stock so purchased, together with any other securities or property to
which the Holder hereof is entitled upon such exercise, shall be delivered to
the Holder hereof by the Company at the Company's expense within a reasonable
time after the rights represented by this Warrant have been so exercised.
Except as provided in clause (b) of this Section 1, in case of a purchase of
less than all the shares which may be purchased under this Warrant, the Company
shall cancel this Warrant and execute and deliver a new Warrant or Warrants of
like tenor for the balance of the shares purchasable under the Warrant
surrendered upon such purchase to the Holder hereof within a reasonable time.
Each stock certificate so delivered shall be in such denominations of
<PAGE>   36
Preferred Stock as may be requested by the Holder hereof and shall be
registered in the name of such Holder or such other name as shall be designated
by such Holder, subject to the limitations contained in Section 2.

          (b)  The Holder, in lieu of exercising this Warrant by the payment of
the Stock Purchase Price pursuant to clause (a) of this Section 1, may elect,
at any time on or before the Expiration Date, to receive that number of shares
of Preferred Stock equal to the quotient of: (i) the difference between (A) the
Per Share Price (as hereinafter defined) of the Preferred Stock, less (B) the
Stock Purchase Price then in effect, multiplied by the number of shares of
Preferred Stock the Holder would otherwise have been entitled to purchase
hereunder pursuant to clause (a) of this Section 1 (or such lesser number of
shares as the Holder may designate in the case of a partial exercise of this
Warrant); over (ii) the Per Share Price. Election to exercise under this
section (b) may be made by delivering a signed form of subscription to the
Company via facsimile, to be followed by delivery of the warrant.

          (c)  For purposes of clause (b) of this Section 1, "Per Share Price"
means the product of: (i) the greater of (A) the closing price of the Company's
Common Stock as quoted by NASDAQ or listed on any exchange, whichever is
applicable, as published in the Western Edition of The Wall Street Journal for
the trading day immediately prior to the date of the Holder's election hereunder
or, (B) if applicable at the time of or in connection with the exercise under
clause (b) of this Section 1, the gross sales price of one share of the
Company's Common Stock pursuant to a registered public offering or that amount
which shareholders of the Company will receive for each share of Common Stock
pursuant to a merger, reorganization or sale of assets; and (ii) that number of
shares of Common Stock into which each share of Preferred Stock is convertible.
If the Company's Common Stock is not quoted by NASDAQ or listed on an exchange,
the Per Share Price of the Preferred Stock (or the equivalent number of shares
of Common Stock into which such Preferred Stock is convertible) shall be the
price per share which the Company would obtain from a willing buyer for shares
sold by the Company from authorized but unissued shares as such price shall be
agreed upon by the Holder and the Company or, if agreement cannot be reached
within ten (10) business days of the Holder's election hereunder, as such price
shall be determined by a panel of three (3) appraisers, one (1) to be chosen by
the Company, one (1) to be chosen by the Holder and the third to be chosen by
the first two (2) appraisers. If the appraisers cannot reach agreement within 30
days of the Holder's election hereunder, then each appraiser shall deliver its
appraisal and the appraisal which is neither the highest nor the lowest shall
constitute the Per Share Price. In the event either party fails to choose an
appraiser within 30 days of the Holder's election hereunder, then the appraisal
of the sole appraiser shall constitute the Per Share Price. Each party shall
bear the cost of the appraiser selected by such party and the cost of the third
appraiser shall be borne one-half by each party. In the event either party fails
to choose an appraiser, the cost of the sole appraiser shall be borne one-half
by each party.

     2.   Limitation on Transfer.

          (a)  The Warrant and the Preferred Stock shall not be transferable
except upon the conditions specified in this Section 2, which conditions are
intended to insure compliance with the provisions of the Securities Act of
1933, as amended (the "Securities Act"). Each holder of this Warrant or the
Preferred Stock issuable hereunder will cause any proposed transferee of the
Warrant or Preferred Stock to agree to take and hold such securities to the
provisions and upon the conditions specified in this Section 2.

          (b)  Each certificate representing (i) this Warrant, (ii) the
Preferred Stock, (iii) shares of the Company's Common Stock issued upon
conversion of the Preferred Stock and (iv) any other securities issued in
respect to the Preferred Stock or Common Stock issued upon conversion of the
Preferred Stock upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall (unless otherwise permitted by the
provisions of this Section 2 or unless such securities have been registered
under the Securities Act or sold under Rule 144) be stamped or otherwise
imprinted with a legend substantially in the following form (in addition to any
legend required under applicable state securities laws):

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED
OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH
ACT COVERING SUCH SECURITIES. THE TRANSFER IS MADE IN COMPLIANCE WITH RULE 144
PROMULGATED UNDER SUCH ACT OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR


                                       2
<PAGE>   37
THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE COMPANY, STATING
THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE
REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

          (c)  The Holder of this Warrant and each person to whom this Warrant
is subsequently transferred represents and warrants to the Company (by
acceptance of such transfer) that it will not transfer the Warrant (or
securities issuable upon exercise hereof unless a registration statement under
the Securities Act was in effect with respect to such securities at the time of
issuance thereof) except pursuant to (i) an effective registration statement
under the Securities Act, (ii) Rule 144 under the Securities Act (or any other
rule under the Securities Act relating to the disposition of securities), or
(iii) an opinion of counsel, reasonably satisfactory to counsel for the Company,
that an exemption from such registration is available.

          3.   Shares to be Fully Paid; Reservation of Shares. The Company
covenants and agrees that all shares of Preferred Stock which may be issued upon
the exercise of the rights represented by this Warrant will, upon issuance, be
duly authorized, validly issued, fully paid and nonassessable and free from all
preemptive rights of any shareholder and free of all taxes, liens and charges
with respect to the issue thereof (other than taxes in respect of transfer
occurring contemporaneously or as otherwise specified herein). The Company
further covenants and agrees that during the period within which the rights
represented by this Warrant may be exercised, the Company will at all times have
authorized and reserved, for the purpose of issue or transfer upon exercise of
the subscription rights evidenced by this Warrant, a sufficient number of shares
of authorized but unissued Preferred Stock, or other securities and property,
when and as required to provide for the exercise of the rights represented by
this Warrant. The Company will take all such action as may be necessary to
assure that such shares of Preferred Stock may be issued as provided herein
without violation of any applicable law or regulation, or of any requirements of
any domestic securities exchange upon which the Preferred Stock may be listed.
The Company will not take any action which would result in any adjustment of the
Stock Purchase Price (as defined in Section 4 hereof) (i) if the total number of
shares of Preferred Stock issuable after such action upon exercise of all
outstanding warrants, together with all shares of Preferred Stock then
outstanding and all shares of Preferred Stock then issuable upon exercise of all
options and upon the conversion of all convertible securities then outstanding,
would exceed the total number of shares of Preferred Stock then authorized by
the Company's Articles of Incorporation, or (ii) if the total number of shares
of Common Stock issuable after such action upon the conversion of all such
shares of Preferred Stock together with all shares of Common Stock then
outstanding and then issuable upon exercise of all options and upon the
conversion of all convertible securities then outstanding would exceed the total
number of shares of Common Stock then authorized by the Company's Articles of
Incorporation.

     4.   Adjustment of Stock Purchase Price Number of Shares. The Stock
Purchase Price and the number of shares purchaseable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 4. Upon each adjustment of the Stock
Purchase Price, the Holder of this Warrant shall thereafter be entitled to
purchase, at the Stock Purchase Price resulting from such adjustment, the
number of shares obtained by multiplying the Stock Purchase Price in effect
immediately prior to such adjustment by the number of shares purchaseable
pursuant hereto immediately prior to such adjustment, and dividing the product
thereof by the Stock Purchase Price resulting from such adjustment.

          4.1  Subdivision or Combination of Stock. In case the Company shall
at any time subdivide its outstanding shares of Preferred Stock into a greater
number of shares, the Stock Purchase Price in effect immediately prior to such
subdivision shall be proportionately reduced, and conversely, in case the
outstanding shares of Preferred Stock of the Company shall be combined into a
smaller number of shares, the Stock Purchase Price in effect immediately prior
to such combination shall be proportionately increased.

          4.2  Dividends in Preferred Stock, Other Stock, Property,
Reclassification. If at any time or from time to time the holders of Preferred
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to receive,
without payment therefor,

               (a)  Preferred Stock or any shares of stock or other securities
whether or not such securities are at any time directly or indirectly
convertible into or exchangeable for Preferred Stock, or any rights or



                                       3

<PAGE>   38

options to subscribe for, purchase or otherwise acquire any of the foregoing by
way of dividend or other distribution, or

               (b)  any cash paid or payable otherwise than as a cash dividend,
or

               (c)  Preferred Stock or other or additional stock or other
securities or property (including cash) by way of spinoff, split-up,
reclassification, combination of shares or similar corporate rearrangement,
(other than shares of Preferred Stock issued as a stock split, adjustments in
respect of which shall be covered by the terms of Section 4.1 above).

Then and in each such case, the Holder hereof shall, upon the exercise of this
Warrant, be entitled to receive, in addition to the number of shares of
Preferred stock receivable thereupon, and without payment of any additional
consideration therefore, the amount of stock and other securities and property
(including cash in the cases referred to in clauses (b) and (c) above) which
such Holder would hold on the date of such exercise had he been the holder of
record of such Preferred Stock as of the date on which holders of Preferred
Stock received or became entitled to receive such shares and/or all other
additional stock and other securities and property.

          4.3  Reorganization, Reclassification, Consolidation, Merger or Sale.
If any capital reorganization of the capital stock of the Company, or any
consolidation or merger of the Company with another corporation, or the sale
of all or substantially all of its assets to another corporation shall be
effected in such a way that holders of Preferred Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for
Preferred Stock (Corporate Event), then, as a condition of such reorganization,
reclassification, consolidation, merger or sale, lawful and adequate provisions
shall be made whereby the holder hereof shall thereafter have the right to
purchase and receive (in lieu of the shares of the Preferred Stock of the
Company immediately theretofore purchasable and receivable upon the exercise of
the rights represented hereby) such shares of stock, securities or assets as
may be issued or payable with respect to or in exchange for a number of
outstanding shares of such Preferred Stock equal to the number of shares of
such stock immediately theretofore purchasable and receivable upon the exercise
of the rights represented hereby, provided, however, in the event that 1) the
effective price of such Corporate Event is in excess of the exercise price
hereof effective at the time of the Corporate Event, 2) the consideration
received in such Corporate Event is cash or shares that are of a publicly
traded company listed on a national market or exchange, without restrictions
within 90 days of the close of such Corporate Event, except for those of Rule
144 or 145, and 3) the Company's shareholders own less than 50% of the voting
securities of the surviving entity, then this Warrant shall be deemed exercised
in accordance with the provisions of section 1(b) upon the closing of the
Corporate Event. In any such case, appropriate provision shall be made with
respect to the rights and interests of the holder of this Warrant to the end
that the provisions hereof (including, without limitation, provisions for
adjustments of the Stock Purchase Price and of the number of shares purchasable
and receivable upon the exercise of this Warrant) shall thereafter be
applicable, as nearly as may be possible, in relation to any shares of stock,
securities or assets thereafter deliverable upon the exercise hereof.

          4.4  Sale or Issuance Below Purchase Price. If the Company shall at
any time or from time to time issue or sell any of its Common stock, Preferred
Stock, options to acquire (or rights to acquire such options), or any other
securities convertible into or exercisable for Common Stock, for a
consideration per share less than the Stock Purchase Price in effect
immediately prior to the time of such issue or sale, the Conversion ratio shall
be adjusted in accordance with the Company's Articles of Incorporation.

          4.5  Notice of Adjustment. Upon any adjustment of the Stock Purchase
Price, and/or any increase or decrease in the number of shares purchasable upon
the exercise of this Warrant the Company shall give written notice thereof, by
first class mail, postage prepaid, addressed to the registered holder of this
Warrant at the address of such holder as shown on the books of the Company. The
notice, which may be substantially in the form of Exhibit "A" attached hereto,
shall be signed by the Company's chief financial officer and shall state the
Stock Purchase Price resulting from such adjustment and the increase or
decrease, if any, in the number of shares purchasable at such price upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.


                                       4
<PAGE>   39
          4.6  Other Notices. If at any time:

               (a)  the Company shall declare any cash dividend upon its
Preferred Stock;

               (b)  the Company shall declare any dividend upon its Preferred
Stock payable in stock or make any special dividend or other distribution to
the holders of its Preferred Stock;

               (c)  the Company shall offer for subscription pro rata to the
holders of its preferred Stock any additional shares of stock of any class or
other rights;

               (d)  there shall be any capital reorganization or
reclassification of the capital stock of the Company, or consolidation or merger
of the Company with, or sale of all or substantially all of its assets to,
another corporation;

               (e)  there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company; or

               (f)  the Company shall take or propose to take any other action,
notice of which is actually provided to holders of the Preferred Stock;

               then, in any one or more of said cases, the Company shall give,
by first class mail, postage prepaid, addressed to the holder of this Warrant at
the address of such holder as shown on the books of the Company, (i) at least 20
day's prior written notice of the date on which the books of the Company shall
close or a record shall be taken for such dividend, distribution or subscription
rights or for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, or other action and (ii) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, or other action, at least 20 day's written notice of the date when
the same shall take place. Any notice given in accordance with the foregoing
clause (i) shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Preferred Stock shall be
entitled thereto. Any notice given in accordance with the foregoing clause (ii)
shall also specify the date on which the holders of Preferred Stock shall be
entitled to exchange their Preferred Stock for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding-up, or other action as the case may
be.

          4.7  Certain Events. If any change in the outstanding Preferred Stock
of the Company or any other event occurs as to which the other provisions of
this Section 4 are not strictly applicable or if strictly applicable would not
fairly protect the purchase rights of the Holder of the Warrant in accordance
with the essential intent and principles of such provisions, then the Board of
Directors of the Company shall make an adjustment in the number and class of
shares available under the Warrant, the Stock Purchase Price and/or the
application of such provisions, in accordance with such essential intent and
principles, so as to protect such purchase rights as aforesaid. The adjustment
shall be such as will give the Holder of the Warrant upon exercise for the same
aggregate Stock Purchase Price the total number, class and kind of shares as he
would have owned had the Warrant been exercised prior to the event and had he
continued to hold such shares until after the event requiring adjustment.

     5.   Issue Tax. The issuance of certificates for share of Preferred Stock
upon the exercise of the Warrant shall be made without charge to the Holder of
the Warrant for any issue tax in respect thereof; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Holder of the Warrant being exercised.

     6.   Closing of Books. Provided that the Holder shall be in compliance
with the terms of this Agreement, including but not limited to, Section 2, the
Company will at no time close its transfer books against the transfer of any
Warrant or of any shares of Preferred Stock issued or issuable upon the
exercise of any warrant.


                                       5
<PAGE>   40
     7.   No Voting or Dividend Rights; Limitation of Liability. Nothing
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent as a shareholder in respect of meetings
of shareholders for the election of directors of the Company or any other
matters or any rights whatsoever as a shareholder of the Company. No dividends
or interest shall be payable or accrued in respect of this Warrant or the
interest represented hereby or the shares purchasable hereunder until, and only
to the extent that, this Warrant shall have been exercised. No provisions
hereof, in the absence of affirmative action by the holder to purchase shares of
Preferred Stock, and no more enumeration herein of the rights or privileges of
the Holder hereof, shall give rise to any liability of such Holder for the Stock
Purchase Price or as a shareholder of the Company, whether such liability is
asserted by the Company or by its creditors.

     8.   Intentionally Omitted.

     9.   Registration Rights. The Holder hereof shall be entitled, with respect
to the shares of Preferred Stock issued upon exercise hereof or the shares of
Common Stock or other securities upon conversion of such Preferred Stock as the
case may be, to, and bound by, all of the registration rights and obligations
set forth in the First Amended and Restated Registration Rights Agreement dated
as of July 31, 1998 to the same extent and on the same terms and conditions as
possessed by the Investors thereunder. The Company shall take such action as may
be reasonably necessary to assure that the granting of such registration rights
to the Holder does not violate the provision of such agreement or any of the
Company's charter documents or rights of prior Grantees of registration rights.

     10.  Rights and Obligations Survive Exercise of Warrant. The rights and
obligations of the Company, of the Holder of this Warrant and of the holder of
shares of Preferred Stock issued upon exercise of this Warrant, contained in
Sections 6 and 9 shall survive the exercise of this Warrant.

     11.  Modification and Waiver. This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

     12.  Notices. Any notice, request or other document required or permitted
to be given or delivered to the holder hereof or the Company shall be deemed to
have been given (i) upon receipt if delivered personally or by courier (ii)
upon confirmation of receipt if by telecopy or (iii) three business days after
deposit in the US mail, with postage prepaid and certified or registered, to
each such holder at its address as shown on the books of the Company or to the
Company at the address indicated therefor in the first paragraph of this
Warrant.

     13.  Binding Effect on Successors. This Warrant shall be binding upon any
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets. All of the obligations of the
Company relating to the Preferred Stock issuable upon the exercise of this
Warrant shall survive the exercise and termination of this Warrant. All of the
covenants and agreements of the Company shall inure to the benefit of the
successors and assigns of the holder hereof. The Company will, at the time of
the exercise of this Warrant in whole or in part, upon request of the Holder
hereof but at the Company's expense, acknowledge in writing its continuing
obligation to the Holder hereof in respect of any rights (including, without
limitation, any right to registration of the shares of Common Stock) to which
the holder hereof shall continue to be entitled after such exercise in
accordance with this Warrant; provided, that the failure of the holder hereof
to make any such request shall not affect the continuing obligation of the
Company to the Holder hereof in respect of such rights.

     14.  Descriptive Headings and Governing Law. The descriptive headings of
the several sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. This Warrant
shall be construed and enforced in accordance with, and the rights of the
parties shall be governed by, the laws of the State of California.

          15.     Lost Warrants or Stock Certificates. The Company represents
and warrants to the Holder hereof that upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction, or mutilation of
any Warrant or stock certificate and, in the case of any such loss, theft or
destruction, upon receipt of an indemnity reasonably satisfactory to the
Company, or in the case of any such mutilation upon surrender and cancellation
of such Warrant or stock certificate, the Company at its expense will make and
deliver a new Warrant or stock certificate, of like tenor, in lieu of the lost,
stolen, destroyed or mutilated Warrant or stock certificate.

          16.     Fractional Shares. No fractional shares shall be issued upon
exercise of this Warrant. The Company shall, in lieu of issuing any fractional
share, pay the holder entitled to such fraction a sum in cash equal to such
fraction multiplied by the then effective Stock Purchase Price.

                               PROMISSORY NOTE

$800,000.00                                                 February 26, 1999
                                                         San Jose, California

      The undersigned ("Borrower") promises to pay to the order of VENTURE
LENDING & LEASING II, INC., a Maryland corporation ("Lender") at its office at
2010 North First Street, Suite 310, San Jose, California 95131, or at such
other place as Lender may designate in writing, in lawful money of the United
States of America, the principal sum of Eight Hundred Thousand Dollars
($800,000.00), with Basic Interest thereon from the date hereof until maturity,
whether scheduled or accelerated, at a fixed rate per annum of eight and 40/100
percent (8.40%), and a Terminal Payment in the sum of Eighty Thousand Dollars
($80,000.00) payable on the Maturity Date.

      This Note is one of the Notes referred to in, and is entitled to all the
benefits of, a Loan and Security Agreement dated February 9, 1999, between
Borrower and Lender (the "Loan Agreement"). Each capitalized term not otherwise
defined herein shall have the meaning set forth in the Loan Agreement. The Loan
Agreement contains provisions for the acceleration of the maturity of this Note
upon the happening of certain stated events.

      Principal of and interest on this Note shall be payable as follows:

      On the Borrowing Date, Borrower shall pay (i) Basic Interest, in advance,
on the outstanding principal balance of this Note at the Designated Rate for
the period from the Borrowing Date through February 28, 1999; and (ii) a first
(1st) amortization installment of principal and Basic Interest in the amount of
$25,040.00, in advance for the month of March, 1999 and (iii) a 36th last
amortization installment of principal and Basic Interest in the amount of
$25,040.00, in advance for the month of February, 2002.

      Commencing on the first day of the second full month after the Borrowing
Date, and continuing on the first day of each consecutive month thereafter,
principal and Basic Interest shall be payable, in advance, in thirty-three (33)
equal consecutive installments of Twenty Five Thousand Forty Dollars
($25,040.00) each, with a thirty-fourth (34th) installment equal to the entire
unpaid principal balance and accrued Basic Interest on January 1, 2002. The
Terminal Payment amount shall be payable on March 1, 2002.

      Any unpaid payments of principal or interest on this Note shall bear
interest from their respective maturities, whether scheduled or accelerated, at
a rate per annum equal to the Default Rate. Borrower shall pay such interest on
demand.

      Interest, charges and fees shall be calculated for actual days elapsed on
the basis of a 360-day year, which results in higher interest, charge or fee
payments than if a 365-day year were used. In no event shall Borrower be
obligated to pay interest, charges or fees at a rate in excess of the highest
rate permitted by applicable law from time to time in effect.

      If Borrower is late in making any payment under this Note by more than
five (5) days, Borrower agrees to pay a "late charge" of five percent (5%) of
the installment due, but not less than fifty dollars ($50.00) for any one such
delinquent payment. This late charge may be charged by Lender for the purpose
of defraying the expenses incidental to the handling of such delinquent
amounts. Borrower acknowledges that such late charge represents a reasonable
sum considering all of the circumstances existing on the date of this Note and
represents a fair and reasonable estimate of the costs that will be sustained
by Lender due

<PAGE>   52
to failure of Borrower to make timely payments. Borrower further agrees that
proof of actual damages would be costly and inconvenient. Such late charge
shall be paid without prejudice to the right of Lender to collect any other
amounts provided to be paid or to declare a default under this Note or any of
the other Loan Documents or from exercising any other rights and remedies of
Lender.

     This Note shall be governed by, and construed in accordance with, the laws
of the State of California.
