$0.001 per share ("New Focus Common Stock").

      D. As a condition and an inducement to New Focus to enter into this
Agreement, the Company Shareholder has concurrently herewith entered into a

      I. The Company and New Focus desire to make certain representations,

      NOW, THEREFORE, in consideration of the covenants, promises,

the parties), intending to be legally bound hereby, the parties agree as
follows:

                                    ARTICLE 1
                                   THE MERGER

      1.1 The Merger. At the Effective Time and upon the terms and subject to
the conditions of this Agreement and the applicable provisions of California Law
and Delaware Law, Merger Sub shall be merged with and into the Company, the
separate corporate existence of Merger Sub shall cease, and the Company shall
continue as the surviving corporation. The Company is sometimes referred to
herein as the "Surviving Corporation."

      1.2 Effective Time. Unless this Agreement is earlier terminated pursuant
to Section 8.1, the closing of the Merger (the "Closing") will take place as
promptly as practicable after January 1, 2001, provided that all of the
conditions set forth in Article 6 have been satisfied or waived, at the offices
of Wilson Sonsini Goodrich & Rosati, 650 Page Mill Road, Palo Alto, California,
unless another place or time is agreed to by New Focus and the Company. The date
upon which the Closing actually occurs is herein referred to as the "Closing
Date." On the Closing Date, the parties hereto shall cause the Merger to be
consummated by filing a Certificate of Merger (or like instrument), in
substantially the form attached hereto as Exhibit D (the "Certificate of
Merger"), with


                                      -2-
<PAGE>   8

the Secretary of State of the State of California and the Secretary of State of
the State of Delaware, in accordance with the relevant provisions of applicable
California Law and Delaware Law (the time of acceptance by the Secretary of
State of the State of Delaware of such filing or such later time as may be
agreed to by the parties and set forth in the Certificate of Merger being
referred to herein as the "Effective Time").

      1.3 Effect of the Merger on Constituent Corporations. At the Effective
Time, the effect of the Merger shall be as provided in the applicable provisions
of California Law and Delaware Law. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all the property, rights,
privileges, powers and franchises of Merger Sub and the Company shall vest in
the Surviving Corporation, and all debts, liabilities, obligations,
restrictions, disabilities and duties of Merger Sub and the Company shall become
the debts, liabilities, obligations, restrictions, disabilities and duties of
the Surviving Corporation.

      1.4 Certificate of Incorporation and Bylaws of Surviving Corporation.

            (a) At the Effective Time, the certificate of incorporation of
Merger Sub, as in effect immediately prior to the Effective Time, shall be the
certificate of incorporation of the Surviving Corporation until thereafter
amended as provided by law and such certificate of incorporation and bylaws of
the Surviving Corporation.

            (b) The bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be the bylaws of the Surviving Corporation until
thereafter amended as provided by such bylaws, the certificate of incorporation
and applicable law.

      1.5 Directors and Officers of Surviving Corporation. The directors of
Merger Sub immediately prior to the Effective Time shall be the directors of the
Surviving Corporation, each to hold office in accordance with the certificate of
incorporation and bylaws of the Surviving Corporation. The officers of Merger
Sub immediately prior to the Effective Time shall be the officers of the
Surviving Corporation, each to hold office in accordance with the bylaws of the
Surviving Corporation.

      1.6 Maximum Number of Shares of New Focus Common Stock to be Issued;
Effect on Outstanding Securities of the Company. The maximum number of shares of
New Focus Common Stock to be issued in exchange for all shares of Company Common
Stock which are issued and outstanding immediately prior to the Effective Time,
as determined in accordance with the terms of this Agreement, shall not exceed
the Total Merger Consideration. On the terms and subject to the conditions of
this Agreement, at the Effective Time, by virtue of the Merger and without any
action on the part of New Focus, the Company or the Company Shareholder, the
following shall occur:

            (a) Conversion of Company Common Stock. Each share of Company Common
Stock issued and outstanding immediately prior to the Effective Time will be
cancelled and extinguished and converted automatically (subject to Section 1.8)
into the right to receive, that number of shares of New Focus Common Stock equal
to the Exchange Ratio, it being understood

                                      -3-
<PAGE>   9

that certain shares of New Focus Common Stock issuable pursuant to this Section
1.6(a) shall be held in escrow in accordance with Article 7 hereof.

            (b) Conversion of Common Stock of Merger Sub. Each share of common
stock, $.001 par value, of Merger Sub issued and outstanding immediately prior
to the Effective Time shall remain issued and outstanding and shall constitute a
share of common stock of the Surviving Corporation.

      1.7 Adjustments to Exchange Ratio. The Exchange Ratio shall be equitably
adjusted to reflect fully the effect of any stock split, reverse split, stock
combination, stock dividend (including any dividend or distribution of
securities convertible into New Focus Common Stock or Company Common Stock),
reorganization, reclassification, recapitalization or other like change with
respect to New Focus Common Stock or Company Common Stock the effective date of
which occurs after the date hereof and prior to the Effective Time.

      1.8 Fractional Shares. No fraction of a share of New Focus Common Stock
will be issued in the Merger, but in lieu thereof, if the Company Shareholder
would otherwise be entitled to a fraction of a share of New Focus Common Stock
(after aggregating all fractional shares of New Focus Common Stock to be
received by such holder), he shall, instead, be entitled to receive from New
Focus an amount of cash (rounded down to the nearest whole cent) equal to the
product of (a) such fraction, multiplied by (b) the Closing Price.

      1.9 Exchange Procedures.

            (a) New Focus Common Stock. As promptly as practicable after the
Closing Date, New Focus shall deposit with the Exchange Agent for exchange in
accordance with this Article 1, the aggregate number of shares of New Focus
Common Stock issuable in exchange for outstanding shares of Company Common Stock
and cash in an amount sufficient to permit the payment of cash in lieu of
fractional shares pursuant to Section 1.8; provided, however, that, on behalf of
the Company Shareholder, New Focus shall deposit into an escrow account a number
of shares of New Focus Common Stock equal to the Escrow Amount.

            (b) Exchange Procedures. After the Effective Time and upon surrender
of the Company Shareholder's certificate representing Company Common Stock,
which was converted into the right to receive shares of New Focus Common Stock
pursuant to Section 1.6 (the "Certificate"), for cancellation to the Exchange
Agent or to such other agent or agents as may be appointed by New Focus,
together with a letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, the Company Shareholder shall be
entitled to receive in exchange therefor a certificate representing the number
of whole shares of New Focus Common Stock (less the number of shares of New
Focus Common Stock to be deposited in the Escrow Funds on the Company
Shareholder's behalf pursuant to Article 7) and cash in lieu of fractional
shares to which such holder is entitled pursuant to Sections 1.6 and 1.8, and
the Certificate so surrendered shall be canceled. As soon as practicable after
the Effective Time, and subject to and in accordance with the provisions of
Article 7, New Focus shall cause to be distributed to the Escrow Agent a
certificate or certificates (in such denominations as may be requested by the
Escrow Agent)

                                      -4-
<PAGE>   10

representing that number of shares of New Focus Common Stock equal to the Escrow
Amount, which certificate shall be registered in the name of the Escrow Agent.
Such shares shall be beneficially owned by the Company Shareholder on whose
behalf such shares were deposited in the Escrow Funds and shall be available to
compensate New Focus as provided in Article 7. Until surrendered, each
outstanding Certificate that, prior to the Effective Time, represented shares of
Company Common Stock will be deemed from and after the Effective Time, for all
corporate purposes, other than the payment of dividends, to evidence the
ownership of the number of full shares of New Focus Common Stock into which such
shares of Company Common Stock shall have been so converted (subject only to, if
applicable, the expiration or early termination of any waiting period under the
HSR Act which is applicable to the holder of such shares) and cash in lieu of
fractional shares.

      1.10 No Further Ownership Rights in Company Common Stock. All shares of
New Focus Common Stock issued upon the surrender for exchange of shares of
Company Common Stock in accordance with the terms hereof (including any cash in
lieu of fractional shares) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
and there shall be no further registration of transfers on the records of the
Company of shares of Company Common Stock which were outstanding immediately
prior to the Effective Time.

      1.11 Exemption From Registration; California Permit. New Focus and the
Company intend that the shares of New Focus Common Stock to be issued pursuant
to Section 1.6 in connection with the Merger will be issued in a transaction
exempt from registration under the Securities Act of 1933, as amended, and the
rules and regulations promulgated by the SEC thereunder (the "Securities Act"),
by reason of Section 3(a)(10) thereof or, pursuant to Section 5.1(c), by reason
of Section 4(2) of the Securities Act. Subject to the provisions of Section
5.1(c), New Focus and the Company intend that the shares of New Focus Common

as are specifically disclosed with respect to specific numbered and lettered
sections and subsections of this Article 2 in the disclosure schedule and
schedule of exceptions (the "Company Disclosure Schedule") delivered herewith

Subsidiary nor any of its ERISA Affiliates is or was a party to any collective
bargaining agreement, and (vii) neither the Company, any Subsidiary nor any of
its ERISA Affiliates has announced or otherwise made any commitment to create or

the contrary, there are no Plans (A) as to which New Focus will be required to
make any contributions or with respect to which New Focus shall have any
obligation or liability whatsoever, whether on behalf of any of the current
employees of the Company or any Subsidiary or on behalf of any other person,
after the Closing, or (B) which New Focus, the Surviving Corporation or any
Subsidiary will not be able to terminate immediately after the Closing in

any related funding agreements thereto (including insurance contracts) including
all amendments, all of which are legally valid and binding and in full force and

which such financial statements shall fairly present the financial condition and
the results of operations of such Plan in accordance with GAAP, consistently
applied, as of such dates.

           (b) Deficiencies; Qualification. None of the Plans nor any trust

term is defined in Section 412 of the Internal Revenue Code, whether or not
waived, since the effective date of said Section 412, and no condition has
occurred or exists which by the passage of time could be expected to result in
an accumulated funding deficiency as of the last day of the current plan year of
any such Plan. Furthermore, neither the Company, any Subsidiary nor any of their

and maintained in substantial compliance with ERISA, the Internal Revenue Code
and all other applicable Laws. All contributions required to be made to each of
the Plans under the terms of that Plan, ERISA, the Internal Revenue Code or any
other applicable Laws have been timely made. Each Plan intended to meet the
requirements for tax-favored treatment under Subchapter B of Chapter 1 of the
Internal Revenue Code is in compliance with such requirements. There are no
Liens against the property of the Company, any Subsidiary or any of their
respective ERISA Affiliates under Section 412(n) of the Internal Revenue Code or
Sections 302(f) or 4068 of ERISA. The Financial Statements properly reflect all
amounts required to be accrued as liabilities to date under each of the Plans.

           (c) Acceleration. Neither the execution and delivery of this
Agreement nor the consummation of any of the transactions contemplated hereby
(whether alone or upon the occurrence of any additional or further acts or
events) will (i) result in any obligation or liability (with respect to accrued
benefits or otherwise) on the part of the Company, New Focus, the Surviving
Corporation, or any of their respective Subsidiaries to the PBGC, to any Plan,
or to any present or former employee, director, officer, shareholder, contractor
or consultant (or any of their dependents) of New Focus, the Surviving
Corporation, or any of their respective Subsidiaries or any

any payment (whether of severance pay or otherwise) becoming due to any such
present or former employee, officer, director, shareholder, contractor, or
consultant, or any of their dependents, or (iii) accelerate the time of payment
or vesting, or increase the amount, of any compensation theretofore or
thereafter due or granted to any employee, officer, director, shareholder,
contractor, or consultant of the Company or any Subsidiary or any of their

provided, funding for benefits under any Plan, (A) there is and will be no
liability of the Company, New Focus, the Surviving Corporation or any of their
respective Subsidiaries in the nature of a retroactive or retrospective rate
adjustment, loss sharing arrangement, or actual or contingent liability as of
the Closing Date, nor would there be any such liability if such insurance policy
were terminated as of the Closing Date, and (B) no insurance company issuing any
such policy is in receivership, conservatorship, bankruptcy, liquidation, or
similar proceeding, and no such proceedings with respect to any insurer are
imminent.

           (d) Litigation. Other than routine claims for benefits under the
Plans, there are no pending, or threatened, Actions or Proceedings involving the
Plans, or the fiduciaries, administrators, or trustees of any of the Plans or
the Company, any Subsidiary or any of their respective ERISA Affiliates as the
employer or sponsor under any Plan, with any of the IRS, the Department of
Labor, the PBGC, any participant in or beneficiary of any Plan or any other
person whomsoever. The Company knows of no reasonable basis for any such claim,
lawsuit, dispute or Action or Proceeding.

           (e) Except as disclosed in Section 2.14(h) of the Company Disclosure
Schedule, there is not in operation, and no proposal has been announced to enter
into or establish, any agreement, arrangement, custom or practice (whether
legally enforceable or not) (each such agreement, arrangement, custom or
practice is referred to herein as a "Scheme") for the payment of, or payment of
a contribution towards, any extra-legal pensions, allowances, lump sums or other
similar benefits on retirement, death, disability, termination of employment
(voluntary or not) or during periods of sickness or disablement, for the benefit
of any director, former director, officer, employee or former employee of the
Company or for the benefit of the dependents on any such person. All obligations
payable by the Company under any Scheme are duly provisioned in the Financial
Statements and are duly funded in accordance with normal practices applicable to
such Schemes and all amounts have been paid in due course and to date there are
no payments outstanding.

           (f) Full particulars of the Schemes have been disclosed, such
particulars being true and not misleading in any way.

           (g) All contributions to the Schemes which are due have been paid by
the due date of payment. There are no expenses outstanding in relation to the
Schemes. In respect of any employee who is covered for lump sum death benefit,
those benefits are fully insured with an insurance company of good repute on
normal terms and all premiums payable have been paid.

           (h) There are no claims or actions in progress or pending, nor any
reason for such claims or actions, in respect of the Schemes, nor are there any
unresolved disputes under the Schemes' internal dispute resolution procedures.

licensed to the Company, Intellectual Property for which a functional substitute

forth in Section 2.17(m) of the Company Disclosure Schedule, and all current and
former employees, consultants and independent contractors of the Company have
executed such an agreement and copies of all such agreements have been provided
to New Focus or made available to New Focus for review, and (ii) none of the
agreements to which the Company is a party substantially in the form of the
"Confidentiality Agreement" attached as Exhibit 2.17 to the Company Disclosure
Schedule supersedes, amends or otherwise modifies any other agreement that (a)
is materially more comprehensive with respect to the terms dealing with the
Company's disclosure of any confidential information and/or trade secrets to any
third-party and/or (b) is materially more restrictive on a third-party's use or
disclosure of such information and/or trade secrets.

systems or material interruptions in the ongoing business of the Company by

store, process, calculate and present calendar dates falling on and after (and
if applicable, spans of time including) January 1, 2000 in substantially the
same manner, and with the same functionality, data integrity and performance, as
such products record, store, process, calculate and present calendar dates on or
before December 31, 1999, or calculate any information dependent on or relating
to such dates. Without limiting the generality of the foregoing, and except as
set forth in Section 2.17(p) of the Company Disclosure Schedule, the Company has
no knowledge of any material issues that have arisen in connection with the
ability of its material IT systems to handle the change of date year from 1999

Contract to which the Company is a party or by which any of its Assets and
Properties are bound, other than rights or licenses to Company Intellectual
Property that are described in the material Contracts and Licenses.

           (r) Section 2.17(r) of the Company Disclosure Schedule sets forth a
list of (x) all software which the Company has licensed from any third party

"freeware" and "shareware" incorporated into any product now or heretofore
shipped by the Company. The Company has all rights necessary to the use of such
software, "freeware" and "shareware."

           (s) The Company has previously provided to New Focus specifications
for standards of performance and functionality for proposed products with
respect to each Product Design. No products based on the Product Designs will
fail to meet or exceed such standards of performance and functionality in any
material respect, the failure of which would be directly or indirectly caused by
a defect in Product Design.

           (t) The Company has taken all commercially reasonable steps to
protect and preserve ownership of Company Owned Intellectual Property. The
Company has secured valid written assignments from all consultants and employees
who contributed to the creation or development of the Company Owned Intellectual

           (s) Revaluation: revalue any of its assets, including writing down
the value of inventory or writing off notes or accounts receivable; or

           (t) Other: take or agree in writing or otherwise to take, any of the
actions described in Section 4.1(a) through Section 4.1(s) above, or any other
action that would reasonably be expected to prevent the Company from performing,
or cause the Company not to perform, its covenants and agreements hereunder.

      4.2 No Solicitation. Until the earlier of the Effective Time and the date
of termination of this Agreement pursuant to the provisions of Section 8.1, the
Company will not take (and since September 15, 2000, inclusive, has not taken),
nor will the Company permit (and since September 15, 2000, inclusive, has not
permitted) any of the Company's Representatives to (directly or indirectly),
take any of the following actions with any Person other than New Focus and its
designees: (a) solicit, encourage, initiate, entertain, review or encourage any
proposals or offers from, or participate in or conduct discussions with or
engage in negotiations with, any Person relating to any offer or proposal, oral,
written or otherwise, formal or informal (a "Competing Proposed Transaction"),
with respect to any possible Business Combination with the Company or any of its
Subsidiaries (whether such Subsidiaries are in existence on the date hereof or
are hereafter organized), (b) provide information with respect to the Company or
any of its Subsidiaries (whether such Subsidiaries are in existence on the date
hereof or are hereafter organized) to any Person, other than New Focus, relating
to (or which the Company believes would be used for the purpose of formulating
an offer or proposal with respect to), or otherwise assist, cooperate with,
facilitate or encourage any effort or attempt by any such Person with regard to,
any possible Business Combination with the Company or any Subsidiary of the
Company (whether such Subsidiary is in existence on the date hereof or are
hereafter organized), (c) agree to, enter into a Contract with any Person, other
than New Focus, providing for, or approve a Business Combination with the
Company or any Subsidiary (whether such Subsidiary is in existence on the date
hereof or are hereafter organized), (d) make or authorize any statement,
recommendation, solicitation or endorsement in support of any possible Business
Combination with the Company or any Subsidiary (whether such Subsidiary is in
existence on the date hereof or are hereafter organized) other than by New
Focus, or (e) authorize or permit any of the Company's Representatives to take
any such action. The Company shall immediately cease and cause to be terminated
any such contacts or negotiations with any Person relating to any such
transaction or Business Combination. In addition to the foregoing, if the
Company receives prior to the Effective Time or the termination of this
Agreement any offer or proposal (formal or informal, oral, written or otherwise)
relating to, or any inquiry or contact from any Person with respect to, a
Competing Proposed Transaction, the Company shall immediately notify New Focus
thereof and provide New Focus with the details thereof, including the identity
of the Person or Persons making such offer or proposal, and will keep New Focus
fully informed on a current basis of the status and details of any such offer or
proposal and of any modifications to the terms thereof; provided, however, that
this provision shall not in any way be deemed to limit the


                                      -34-
<PAGE>   40
obligations of the Company and its Representatives set forth in the previous
sentence; provided further, that the Company will not be required to provide to
New Focus information that would result in a violation of a written
confidentiality agreement, executed by the Company prior to September 15, 2000.
Each of the Company and New Focus acknowledge that this Section 4.2 was a
significant inducement for New Focus to enter into this Agreement and the
absence of such provision would have resulted in either (i) a material reduction
in the consideration to be paid to the Company Shareholder in the Merger or (ii)
a failure to induce New Focus to enter into this Agreement.


                                    ARTICLE 5
                             ADDITIONAL AGREEMENTS

     5.1  Permit Application.

            (a) As soon as reasonably practicable after the execution of this
Agreement but no later than thirty (30) days thereafter, New Focus shall
prepare, with the cooperation of the Company, and file the Permit Application.
New Focus and the Company shall each use commercially reasonable efforts to
cause the Permit Application to comply with the requirements of applicable
federal and state laws. Each of New Focus and the Company agrees to provide
promptly to the other such information concerning its business and financial
statements and affairs as, in the reasonable judgment of the providing party or
its counsel, may be required or appropriate for inclusion in the Permit
Application, or in any amendments or supplements thereto, and to cause its
counsel and auditors to cooperate with the other's counsel and auditors in the
preparation and completion of the Permit Application. The Company will promptly
advise New Focus, and New Focus will promptly advise the Company, in writing if
at any time prior to the Effective Time either the Company or New Focus, as
applicable, shall obtain knowledge of any facts that might make it necessary or
appropriate to amend or supplement the Permit Application in order to make the
statements contained or incorporated by reference therein not misleading or to
comply with applicable law. Anything to the contrary contained herein
notwithstanding, New Focus shall not include in the Permit Application any
information with respect to the Company or its affiliates or associates, the
form and content of which information shall not have been approved by the
Company prior to such inclusion.

            (b) In the event that it is determined by New Focus, following
consultation with the Company, that the California Permit cannot be obtained, or
cannot reasonably be expected to be obtained, in time to permit the Closing to
occur on or before the Outside Date, then New Focus and the Company shall use
commercially reasonable efforts to effect the issuance of the shares of New
Focus Common Stock to be issued pursuant to Section 1.6 in a private placement
pursuant to Section 4(2) of the Securities Act on terms and conditions that are
reasonably satisfactory to New Focus. The parties hereto acknowledge and agree
that in such event: (i) as a condition to effecting such issuance as a private
placement pursuant to Section 4(2) of the Securities Act, New Focus shall be
entitled to obtain from the Company Shareholder a Shareholder Certificate in the
form attached hereto as Exhibit E (or such other form as shall be reasonably
satisfactory to New Focus) (the "Shareholder Certificate") and that New Focus
will be relying upon the representations made by the Company Shareholder in the
applicable Shareholder Certificate in connection with the issuance of


                                      -35-

<PAGE>   41

New Focus Common Stock to such shareholder; (ii) the shares of New Focus Common
Stock so issued pursuant to Section 1.6 will not be registered under the
Securities Act and will constitute "restricted securities" within the meaning of
the Securities Act; and (iii) the certificate(s) representing the shares of New
Focus Common Stock shall bear appropriate legends to identify such privately
placed shares as being restricted under the Securities Act, to comply with
applicable state securities laws and, if applicable, to notice the restrictions
on transfer of such shares.

     5.2 Shareholder Approval. As soon as reasonably practicable following the
execution and delivery of this Agreement, the Company shall give written notice
of this Agreement and the proposed Merger to the Company Shareholder and to take
all other action necessary in accordance with California Law and its articles of
incorporation and bylaws to secure the written consent of the Company
Shareholder ("Company Shareholder Action"). The Company shall consult with New
Focus regarding the date of the Company Shareholder Action. The Company shall
obtain from the Company Shareholder a proxy or written consent in favor of the
Merger and this Agreement and shall take all other action necessary or advisable
to secure the vote or written consent of the Company Shareholder required to
effect the Merger.

     5.3 Access to Information. Between the date of this Agreement and the
earlier of the Effective Time or the termination of this Agreement, upon
reasonable notice, the Company shall (a) give New Focus and its officers,
employees, accountants, counsel, financing sources and other agents and
representatives full access to all buildings, offices, and other facilities and
to all Books and Records of the Company, whether located on the premises of the
Company or at another location; (b) permit New Focus to make such inspections as
it, in its sole discretion, may require, including, without limitation,
investigation and testing of the condition of any improvements at any property
owned or leased by the Company and the condition of the subsurface soil and
groundwater on such properties; (c) cause its officers to furnish New Focus such
financial, operating, technical and product data and other information with
respect to the business and Assets and Properties of the Company as New Focus
from time to time may request, including financial statements and schedules; (d)
allow New Focus the opportunity to interview such employees and other personnel
and Affiliates of the Company with the Company's prior written consent, which
consent shall not be unreasonably withheld or delayed; and (e) assist and
cooperate with New Focus in the development of integration plans for
implementation by New Focus and the Surviving Corporation following the
Effective Time; provided, however, that no investigation pursuant to this
Section 5.3 shall affect or be deemed to modify any representation or warranty
made by the Company herein.

     5.4 Confidentiality. Each of the parties hereto shall (and shall cause each
of its representatives to) not disclose any information provided by the other
party with respect to the negotiation and execution of this Agreement or the
consummation of the transactions contemplated hereby, including for the purposes
of due diligence ("Confidential Information"), and shall (and shall cause each
of its representatives to) use the Confidential Information only with respect to
the consummation of the transactions contemplated hereby or as otherwise
provided by this Agreement; provided, however, that the following shall be
deemed not to be Confidential Information: (a) information that the receiving
party can demonstrate was already in its possession prior to the disclosure
thereof by the other party, (b) information that is generally known to the
public and did


                                      -36-

<PAGE>   42

not become so known through the violation of this Section 5.4 by the receiving
party or its representatives, (c) information that becomes available to the
receiving party on a non-confidential basis from a source other than the other
party or its representatives, provided that such source is not know by the
receiving party to be bound by a contractual, legal or fiduciary obligation of
confidentiality to the other party with respect to that information, and (d)
information that is required to be disclosed by law or by the rules and
regulations of the NASD. The Company acknowledges that New Focus Common Stock is
publicly traded and that any Confidential Information with respect to New Focus
could be considered to be material non-public information within the meaning of
U.S. federal and state securities laws. Accordingly, the Company acknowledges
and agrees not to (and shall inform each of its officers, directors and
employees not to) engage in any transactions in New Focus's Common Stock in
violation of applicable insider trading laws.

     5.5 Expenses. Whether or not the Merger is consummated, all fees and
expenses incurred in connection with the Merger including all legal, accounting,
financial advisory, consulting and all other fees and expenses of third parties
("Third Party Expenses") incurred by a party in connection with the negotiation
and effectuation of the terms and conditions of this Agreement and the
transactions contemplated hereby, shall be the obligation of the respective
party incurring such fees and expenses. New Focus shall have the right to
approve Third Party Expenses to be incurred by the Company between the date
hereof and the Closing, including necessary fees and expenses of legal counsel,
accountants, financial advisors, auditors and tax advisors, which such approvals
will not be unreasonably withheld, and the Company shall not pay any such Third
Party Expenses that have not been so approved. Section 2.24 of the Company
Disclosure Schedule includes the Third Party Expenses reasonably estimated to be
incurred by the Company and New Focus hereby approves such Third Party Expenses.

     5.6 Public Disclosure. Unless otherwise required by Law (including federal
and state securities laws) or, as to New Focus, by the rules and regulations of
the NASD, prior to the Effective Time, no public disclosure (whether or not in
response to any inquiry) of the existence of any subject matter of, or the terms
and conditions of, this Agreement shall be made by any party hereto unless
approved by New Focus and the Company prior to release; provided, however, that
such approval shall not be unreasonably withheld or delayed.

     5.7 Approvals. The Company shall use commercially reasonable efforts to
obtain all Approvals from Governmental or Regulatory Authorities or under any of
the Contracts or other agreements as may be required in connection with the
Merger (all of which Approvals are set forth in the Company Disclosure Schedule)
so as to preserve all rights of and benefits to the Company thereunder and New
Focus shall provide the Company with such assistance and information as is
reasonably required to obtain such Approvals.

     5.8 FIRPTA Compliance. On or prior to the Closing Date, the Company shall
deliver to New Focus a properly executed statement in a form reasonably
acceptable to New Focus for purposes of satisfying New Focus's obligations under
Treasury Regulation Section 1.1445-2(c)(3).

     5.9 Notification of Certain Matters. The Company shall give prompt notice
to New Focus, and New Focus shall give prompt notice to the Company, of (a) the
occurrence or non-occurrence of


                                      -37-

<PAGE>   43

any event, the occurrence or non-occurrence of which is likely to cause any
representation or warranty of the Company or New Focus, respectively, contained
in this Agreement to be untrue or inaccurate at or prior to the Closing Date and
(b) any failure of the Company or New Focus, as the case may be, to comply with
or satisfy any covenant, condition or agreement to be complied with or satisfied
by it hereunder; provided, however, that the delivery of any notice pursuant to
this Section 5.9 shall not limit or otherwise affect any remedies available to
the party receiving such notice.

     5.10 Additional Documents and Further Assurances; Cooperation. Each party
hereto, at the request of the other party hereto, shall execute and deliver such
other instruments and do and perform such other acts and things (including all
action reasonably necessary to seek and obtain any and all consents, waivers and
approvals of any Governmental or Regulatory Authority or Person required in
connection with the Merger; provided, however, that New Focus shall not be
obligated to consent to any divestitures or operational limitations or
activities in connection therewith and no party shall be obligated to make a
payment of money as a condition to obtaining any such consent, waiver or
approval) as may be necessary or desirable for effecting completely the
consummation of this Agreement and the transactions contemplated hereby. Each
party agrees to use commercially reasonable efforts to cause the conditions set
forth in Article 6 to be satisfied, where the satisfaction of such conditions
depends on action or forbearance from action by such party.

     5.11 NNM Listing of Additional Shares Application. New Focus shall, to the
extent required by the rules of the NNM, notify the NNM of the shares of Common
Stock of New Focus issuable and the shares of New Focus Common Stock required to
be reserved for issuance in connection with the Merger.

     5.12 Company's Auditors. The Company will use commercially reasonable
efforts to cause its management and its independent auditors to facilitate on a
timely basis (a) the preparation of financial statements (including pro forma
financial statements if required) as required by New Focus to comply with
applicable SEC regulations, (b) the review of any Company audit or review work
papers, including the examination of selected Financial statements and data, (c)
the delivery of such representations from the Company's independent accountants
as may be reasonably requested by New Focus or its accountants, and (d) the
securing of a binding fee commitment (on terms similar to those in place on the
date of this Agreement) with respect to consents and comfort letters requested
by New Focus after the Closing.

     5.13 Takeover Statutes. If any Takeover Statute is or may become applicable
to the transactions contemplated hereby, the board of directors of the Company
will grant such approvals and take such actions as are necessary so that the
transactions contemplated by this Agreement and the Ancillary Agreements may be
consummated as promptly as practicable on the terms contemplated hereby and
otherwise act to eliminate the effects of any Takeover Statute on any of the
transactions contemplated hereby.

     5.14 Treatment as Reorganization. The Parties intend the Merger to qualify
as a reorganization under Section 368(a) of the Code. Each Party hereto has
consulted with his or its own tax adviser in connection with the Merger and
related transactions and no Party makes any


                                      -38-

<PAGE>   44

representation or warranty with regard to the qualification of the Merger
as a reorganization. Each of the Company, the Company Shareholder and New Focus
shall not take any action that could reasonably be expected to prevent the
Merger from qualifying, as a reorganization under Section 368(a) of the Code.
Each of the Company, the Company Shareholder and New Focus shall report the
Merger as a reorganization within the meaning of Section 368 of the Code, unless
otherwise required pursuant to a "determination" within the meaning of Section
1313(a) of the Code. The Company Shareholder shall bear all risks and expenses
associated with any failure of the Merger to so qualify for any reason, other
than any such failure that is caused by a breach of this Agreement by New Focus.

     5.15 Tax Matters. The Company Shareholder shall be responsible for timely
filing all federal and state income tax returns of the Company for taxable
periods ending on or prior to the Effective Time of the Merger and has paid or
will pay all income taxes attributable to the income of the Company's business
or operation or ownership of such business or the assets used therein arising on
or prior to the date of incorporation of the Company. Such returns will be
prepared and filed in accordance with applicable law and in a manner consistent
with past practices. New Focus and the Company, on the one hand, and the Company
Shareholder, on the other hand, will make available to the other, as reasonably
requested, all information, records or documents relating to the liability for
Taxes of the Company for all periods ending on or prior to the Effective Time
and will preserve such information, records or documents until the expiration of
any applicable statute of limitations or extensions thereof.

     5.16 Information Technology Access. In furtherance of the Company's
agreement in Section 5.3 and to facilitate prompt integration following the
Closing of the Company's information technology ("IT") inventory (e.g., voice
and data network services and software and hardware, licenses,
financial/accounting software, IT budgets, etc.) with New Focus's, the Company
will provide New Focus and its Representatives with access to the Company's IT
inventory, as well as the Company's personnel responsible for such IT inventory.
Because of the substantial lead time that may be required to order and install
new software and hardware to integrate the Company's IT systems with New
Focus's, and the importance of a smooth integration of such IT systems promptly
after the Closing, the Company agrees that New Focus may order, either in New
Focus's name or, if required by the vendor, the Company's name, any new IT
services, hardware and software that New Focus believes will be needed at the
Company's facilities in order to integrate New Focus's and the Company's
respective operations following the Closing. The Company will cooperate with New
Focus in the installation of such IT systems, hardware and software prior to and
in anticipation of the Closing, including providing New Focus with reasonable
access to and use of the Company's appropriate personnel. If required by the
vendor, at New Focus's request, the Company will place IT systems, hardware and
software orders in the Company's name. For clarity, it is the parties' intent
not to connect any of the ordered services or systems prior to the Closing. New
Focus and the Company agree to cooperate with each other to minimize any
potential disruption to the Company's business from the IT integration efforts;
provided, however, that New Focus will not have any liability to the Company for
any such disruption or as may otherwise result from the IT integration efforts,
except as may be directly caused by New Focus's gross negligence or willful
misconduct; and provided further that in no event will New Focus have any
liability to the Company for any


                                      -39-

<PAGE>   45

indirect, incidental, consequential, special or speculative damages, including
damages for loss of profits or use, business interruption or loss of goodwill,
irrespective of whether such damages arise under contract, tort, statute or
otherwise and whether or not the Company has given New Focus advance notice of
the possibility of such damages. If the Closing does not occur, other than
because of the Company's breach of the Merger Agreement, New Focus will
reimburse the Company for its reasonable and documented out-of-pocket costs
incurred by it in connection with the ordering and installation of IT services,
hardware and software. If New Focus is so required to reimburse the Company, New
Focus will own any such hardware and software and will pay for its removal from
Company premises. New Focus and the Company will cooperate in the removal of any
such hardware or software so as to minimize any disruption to the Company's
business. In addition, if the Closing does not occur, the Company will cooperate
with New Focus in canceling any orders for IT services, hardware or software and
will otherwise act to minimize the costs which might be incurred in connection
with the IT integration efforts.

     5.17 Change of Merger Form. The Company agrees that in the event New Focus
requests that the transactions contemplated hereby be effected through a
different form of merger than the form presently contemplated herein, and
provided that the alternative form of merger is in any event intended to qualify
as a tax-free reorganization and otherwise achieves the ends described herein
without material deviation, the Company shall cooperate with New Focus in
effecting the alternative form of merger and will take all reasonably necessary
action towards such end, including the execution of any amendments to this
Agreement (provided that such amendments relate only to the alternative form of
merger and any related matters and do not include any other substantive changes
not otherwise agreed between the parties).

     5.18 Intellectual Property. The Company shall give New Focus prompt notice
that any Person shall have (a) commenced, or shall have notified the Company
that it intends to commence, an Action or Proceeding or (b) provided the Company
with notice, in either case which allege(s) that any of the Intellectual
Property, including the Company Intellectual Property, presently embodied, or
proposed to be embodied, in the Company's products or utilized in any
development tools (including standard cells) or design environments designed or
modified by the Company infringes or otherwise violates the intellectual
property rights of such Person, is available for licensing from a potential
licensor providing the notice or otherwise alleges that the Company does not
otherwise own or have the right to exploit such Intellectual Property, including
the Company Intellectual Property. The Company shall cooperate with New Focus in
making arrangements, prior to the Closing Date, reasonably satisfactory to New
Focus to effect the assignment to the Company of (a) Company Intellectual
Property created by the Founders related to the Company's business including
such Intellectual Property created by the Company's founders prior to the
Company's incorporation, which was not created for or on behalf of former
employers, and (b) all Company Intellectual Property created by employees and
consultants which was created for or on behalf of the Company, and to obtain the
cooperation of such Persons to complete all appropriate patent filings related
thereto. The Company shall take commercially reasonable actions to maintain,
perfect, preserve or renew the Company Registered Intellectual Property,
including the payment of any registration, maintenance, renewal fees, annuity
fees and taxes or the filing of any documents, applications or certificates
related thereto, and to promptly respond and prepare to respond to all requests,
related to


                                      -40-

<PAGE>   46

the Company Registered Intellectual Property, received from Governmental or
Regulatory Authorities. At the Closing, the Company will notify New Focus of all
actions which must be taken within the one hundred twenty (120) days following
the Closing Date and which are necessary to maintain, perfect, preserve or renew
the Company Registered Intellectual Property, including the payment of any
registration, maintenance, renewal fees, annuity fees and taxes or the filing of
any documents, applications or certificates related thereto.

     5.19 Delivery of Stock Ledger and Minute Book of the Company. The Company
shall deliver its ledger and minute book to New Focus at the Closing.

     5.20 Registration of Patent Assignments. The Company shall promptly after
the date hereof record any assignments to the Company of Company Registered
Intellectual Property at the request of New Focus.

     5.21 Execution of Support Agreement and Non-Competition Agreement. Prior to
November 1, 2000, the Company shall provide to New Focus an original execution
copy of the Support Agreement and original execution copy of the Employment and
Non-Competition Agreement for the Company Shareholder.

     5.22 Execution of Employment and Non-Solicitation Agreements. Prior to
November 25, 2000, the Company shall provide to New Focus original execution
copies of the Employment and Non-Competition Agreements for the individuals
identified on Schedule 5.21.

     5.23 Preparation of Financial Statements. The Company shall cause audited
financial statements and/or financial statements prepared in accordance with
GAAP if so requested by New Focus and shall cooperate in the preparation of, and
provide any information pertaining to the financial condition of the Company
required to be included in, any SEC Documents.

warranties, covenants and agreements of the other party contained in this
Agreement or in any instrument delivered pursuant to this Agreement. Except for

     7.3 Escrow Provisions.

          (a) Establishment of the General Escrow Fund. At or promptly following
the Effective Time, the General Escrow Amount, without any act of the Company
Shareholder, will be deposited with the Escrow Agent, such deposit to constitute
an escrow fund (the "General Escrow Fund") to be governed by the terms set forth
herein. The Company Shareholder shall be entitled to all voting rights with
respect to the New Focus Common Stock held in escrow on its behalf. The Company
and the Company Shareholder jointly and severally indemnify and hold New Focus,
the Surviving Corporation and their officers, directors, affiliates, lenders,
successors and assigns (the "Indemnitees") harmless against all claims, losses,
liabilities, damages, deficiencies, costs and expenses, including, without
limitation, reasonable attorneys' and experts' fees and expenses of
investigation and defense (hereinafter individually a "Loss" and collectively
"Losses") incurred by New Focus, the Surviving Corporation or any other
Indemnitee directly or indirectly as a result of or in connection with (i) any
inaccuracy or breach of a representation or warranty of the Company contained in
this Agreement or in the Ancillary Agreements or in any instrument delivery
pursuant to this Agreement or (ii) any failure by the Company to perform or
comply with any covenant contained in this Agreement or in the Ancillary
Agreements or in any instrument delivery pursuant to this Agreement. The General
Escrow Fund shall be available to compensate New Focus and its affiliates from
any such Loss. The Company Shareholder shall not have any right of contribution
from the Company with respect to any Loss claimed by New Focus. All
indemnification under this Section 7.2(a) shall be made exclusively by means of
claims against the General Escrow Fund, and, except as set forth in the
following sentence, no Indemnitee shall look to the Company Shareholder for
indemnification or contribution except for the General Escrow Fund and as set
forth in Section 7.2(b). Notwithstanding the foregoing, nothing in this
Agreement shall limit any remedy to which New Focus shall be entitled against
the Company Shareholder for his fraud or intentional misrepresentation. In
addition to indemnification for any Losses, as set forth above, if prior to the
Expiration Date of the General Escrow Period, the chief financial officer of New
Focus shall deliver to the Escrow Agent a certificate duly signed by the chief
financial officer of New Focus certifying that the Company Shareholder ceased to
be an employee of New Focus or of a New Focus


                                      -45-

<PAGE>   51

Subsidiary prior to the Expiration Date for any reason other than "Involuntary
Termination" or termination without "Cause" (as those terms are defined in the
Employment and Non-Competition Agreement) (such certificate being referred to
herein as a "Certificate of Non-Employment"), then the Escrow Agent shall
immediately cause the General Escrow Amount, without any further action of New
Focus, the Company Shareholder or any other party, to be distributed in whole to
New Focus, and New Focus shall indemnify the Escrow Agent for such transfer.

          (b) Establishment of the Special Escrow Fund. At or promptly following
the Effective Time, the Special Escrow Amount, without any act of the Company
Shareholder, will be deposited with the Escrow Agent, such deposits to
constitute an escrow fund (the "Special Escrow Fund") to be governed by the
terms set forth herein. The Company Shareholder shall be entitled to all voting
rights with respect to the New Focus Common Stock held in escrow on its behalf.
The Company and the Company Shareholder agree that the Special Escrow Fund will
be distributed in whole to New Focus and the Surviving Corporation upon delivery
to the Escrow Agent of a Certificate of Non-Employment prior to the Expiration
Date, in accordance with Section 7.2(a).

          (c) General Escrow Period. Distribution upon Termination of General
Escrow Period. Subject to the following requirements, the General Escrow Fund
shall be in existence immediately following the Effective Time and shall
terminate upon the earlier to occur of (i) the termination of the Company
Shareholder's status as an employee of New Focus or its subsidiary or (ii) 11:59
p.m., Pacific time, on the date that is one year from the Closing Date (the
"General Escrow Period"); provided, however, that, with respect to
indemnification for any Loss, the General Escrow Period shall not terminate with
respect to any amount which, in the reasonable judgement of New Focus, subject
to the objection of the Shareholder Representative and the subsequent
arbitration of the matter in the manner provided in paragraph (i) below, is
necessary to satisfy any claims that are either threatened in writing or are
pending but unsatisfied and that are specified in any Officer's Certificate
delivered to the Escrow Agent prior to termination of such General Escrow Period
with respect to facts and circumstances existing prior to the termination of
such General Escrow Period. As soon as all such claims have been resolved the
Escrow Agent shall notify New Focus of its intent to deliver to the Company
Shareholders the remaining portion of the General Escrow Fund not required to
satisfy such claims (the "General Settlement Amount"). As soon as all such
claims, if any, have been resolved, and provided that New Focus has not
delivered a Certificate of Non-Employment to the Escrow Agent, in accordance
with Section 7.2(a), the Escrow Agent shall deliver to the Company Shareholder
the remaining portion of the Escrow Funds not required to satisfy such claims.
If the Company Shareholder would otherwise be entitled to a fraction of a share
of New Focus Common Stock, he shall, instead, be entitled to receive from New
Focus an amount of cash (rounded down to the nearest whole cent) equal to the
product of (a) such fraction, multiplied by (b) the Closing Price. New Focus
shall use its commercially reasonable efforts to have such shares and cash
delivered in a timely manner after such resolution.

          (d) Special Escrow Period; Distribution upon Termination of Special
Escrow Period. Subject to the following requirements, the Special Escrow Fund
shall be in existence during the Special Escrow Period. Upon the Expiration Date
of the Special Escrow Period, and provided that New Focus has not delivered a

                                      -46-

<PAGE>   52

with Section 7.2(a), the Escrow Agent shall deliver to the Company Shareholder
the Special Escrow Amount. If the Company Shareholder would otherwise be
entitled to a fraction of a share of New Focus Common Stock, he shall, instead,
be entitled to receive from New Focus an amount of cash (rounded down to the
nearest whole cent) equal to the product of (a) such fraction, multiplied by (b)
the Closing Price. Upon the Expiration Date of the Special Escrow Period, and
provided that New Focus has not delivered a Certificate of Non-Employment to the
Escrow Agent , the Escrow Agent and New Focus shall use their commercially
reasonable efforts to have, with respect to the Escrow Agent, such shares and,
with respect tot New Focus, such cash, if any, delivered in a timely manner
after such resolution.

          (e) Recourse to the Escrow Funds. The Escrow Funds shall be available
to compensate the Indemnitees for any and all (i) Losses (whether or not
involving a Third Party Claim), incurred or sustained by New Focus or any other
Indemnitee as a result of any inaccuracy in or breach (or any claim by any third
party alleging, constituting or involving an inaccuracy or breach) of any
representation, warranty, covenant or agreement of the Company contained herein
or in the Ancillary Agreements or in any instrument delivered pursuant to this
Agreement or (ii) to compensate New Focus in the event of the Company
Shareholder's employment termination prior to the Expiration Date. New Focus and
the Company each acknowledge that such Losses, if any, or the Company
Shareholder not continuing to be employed by New Focus at least until the
Expiration Date of would relate to unresolved contingencies existing at the
Effective Time, which if resolved at the Effective Time would have led to a
reduction in the aggregate Merger consideration to be paid to the Company
Shareholder. The Company Shareholder shall not have any liability under this
Agreement of any sort whatsoever in excess of the Escrow Funds for breach by the
Company of any of its representations or warranties contained in this Agreement,
the Ancillary Agreements or in any other instrument or document required to be
delivered pursuant to this Agreement in connection herewith, except in the event
of fraud or willful misconduct (i.e., a fraudulent or willful breach of a
representation or warranty, but excluding a negligent or reckless breach). In
the event of such a fraudulent breach, New Focus shall have all remedies
available at law or in equity (including for tort) with respect to such breach.

          (f) Protection of Escrow Funds.

               (i) The Escrow Agent shall hold and safeguard the Escrow Funds
during the Escrow Period, shall treat such fund as a trust fund in accordance
with the terms of this Agreement and not as the property of New Focus and shall
hold and dispose of the Escrow Funds only in accordance with the terms hereof.

               (ii) Any shares of New Focus Common Stock or other Equity
Equivalents securities issued or distributed by New Focus ("New Shares") in
respect of New Focus Common Stock in the Escrow Funds which have not been
released from the Escrow Funds shall be added to the Escrow Funds. New Shares
issued in respect of shares of New Focus Common Stock which have been released
from the Escrow Funds shall not be added to the Escrow Funds but shall be
distributed to the record holders thereof. Cash dividends on New Focus Common
Stock shall not be


                                      -47-

<PAGE>   53

added to the Escrow Funds but shall be distributed to the record holders of the
New Focus Common Stock on the record date set for any such dividend.

               (iii) The Company Shareholder shall have voting rights with
respect to the shares of New Focus Common Stock contributed to the Escrow Funds
by the Company Shareholder (and on any voting securities added to the Escrow
Funds in respect of such shares of New Focus Common Stock).

          (g) Indemnification Claims Upon the General Escrow Fund.

               (i) Upon receipt by the Escrow Agent at any time on or before the
last day of the General Escrow Period of a certificate signed by an Authorized
Officer of New Focus (an "Officer's Certificate"): (A) stating that New Focus or
another New Focus Indemnitee has paid or properly accrued or reasonably
anticipates that it will have to pay or accrue Losses, directly or indirectly,
as a result of any inaccuracy or breach (or any claim by any third party
alleging, constituting or involving an inaccuracy or breach) of any
representation, warranty, covenant or agreement of the Company contained in this
Agreement or in any of the Ancillary Agreements or in any instrument or
agreement delivered pursuant to this Agreement, and (B) specifying in reasonable
detail the individual items of Losses included in the amount so stated, the date
each such item was paid or properly accrued, or the basis for such anticipated
liability, and the nature of the misrepresentation, breach of warranty,
agreement or covenant to which such item is related, the Escrow Agent shall,
subject to the provisions of Section 7.2(h), deliver to New Focus out of the
General Escrow Fund, as promptly as practicable, shares of New Focus Common
Stock held in the General Escrow Fund in an amount equal to such Losses. Where
the basis for a claim upon the General Escrow Fund by New Focus is that New
Focus reasonably anticipates that it will pay or accrue a Loss, no payment will
be made from the General Escrow Fund for such Loss unless and until such Loss is
actually paid or accrued.

               (ii) For the purposes of determining the number of shares of New
Focus Common Stock to be delivered to New Focus out of the General Escrow Fund
pursuant to Section 7.2(a) or (g) or to be retained in the General Escrow Fund
after the General Escrow Period pursuant to Section 7.2(c), the shares of New
Focus Common Stock shall be valued at the Closing Price.

          (h) Objections to Claims. At the time of delivery of any Officer's
Certificate to the Escrow Agent, a duplicate copy of such certificate shall be
delivered to the Shareholder Agent and for a period of thirty (30) days after
such delivery, the Escrow Agent shall make no delivery to New Focus of any
General Escrow Amount pursuant to Section 7.2(g). After the expiration of such
thirty (30) day period, the Escrow Agent shall make delivery of shares of New
Focus Common Stock from the Escrow Funds in accordance with Section 7.2(g),
provided that no such payment or delivery may be made to the extent the
Shareholder Agent shall object in a written statement to the claim made in the
Officer's Certificate, and such statement shall have been delivered to the
Escrow Agent prior to the expiration of such thirty (30) day period.

          (i) Resolution of Conflicts; Arbitration.


                                      -48-

<PAGE>   54

               (i) In case the Shareholder Agent shall object in writing to all
or any portion of any claim or claims made in any Officer's Certificate, the
Shareholder Agent and New Focus shall attempt in good faith to agree upon the
rights of the respective parties with respect to each of such claims. If the
Shareholder Agent and New Focus should so agree, a memorandum setting forth such
agreement shall be prepared and signed by both parties and shall be furnished to
the Escrow Agent. The Escrow Agent shall be entitled to rely on any such
memorandum and distribute shares of New Focus Common Stock from the General
Escrow Fund in accordance with the terms thereof.

               (ii) If no such agreement can be reached after good faith
negotiation, either New Focus or the Shareholder Agent may demand arbitration of
the dispute unless the amount of the damage or Loss is at issue in a pending
Action or Proceeding involving a Third Party Claim, in which event arbitration
shall not be commenced until such amount is ascertained or both parties agree to
arbitration; and in either event the matter shall be settled by arbitration
conducted by three arbitrators, one selected by New Focus and one selected by
the Shareholder Agent, and the two arbitrators selected by New Focus and the
Shareholder Agent shall select a third arbitrator. The arbitrators shall set a
limited time period and establish procedures designed to reduce the cost and
time for discovery of information relating to any dispute while allowing the
parties an opportunity, adequate as determined in the sole judgment of the
arbitrators, to discover relevant information from the opposing parties about
the subject matter of the dispute. The arbitrators shall rule upon motions to
compel, limit or allow discovery as they shall deem appropriate given the nature
and extent of the disputed claim. The arbitrators shall also have the authority
to impose sanctions, including attorneys' fees and other costs incurred by the
parties, to the same extent as a court of law or equity, should the arbitrators
determine that discovery was sought without substantial justification or that
discovery was refused or objected to by a party without substantial
justification. The decision of a majority of the three arbitrators as to the
validity and amount of any claim in such Officer's Certificate shall be binding
and conclusive upon the parties to this Agreement, and, the Escrow Agent shall
be entitled to act in accordance with such decision and make or withhold
payments out of the General Escrow Fund in accordance therewith. Such decision
shall be written and shall be supported by written findings of fact and
conclusions regarding the dispute which shall set forth the award, judgment,
decree or order awarded by the arbitrators.

               (iii) Judgment upon any award rendered by the arbitrators may be
entered in any court having competent jurisdiction. Any such arbitration shall
be held in the city and county of Santa Clara, California under the commercial
rules of arbitration then in effect of the American Arbitration Association. For
purposes of this Section 7.2(i), in any arbitration hereunder in which any claim
or the amount thereof stated in the Officer's Certificate is at issue, New Focus
shall be deemed to be the Non-Prevailing Party in the event that the arbitrators
award New Focus less than the sum of one-half of the disputed amount of any
Losses plus any amounts not in dispute; otherwise, the shareholders of the
Company as represented by the Shareholder Agent shall be deemed to be the
Non-Prevailing Party. The Non-Prevailing Party to an arbitration shall pay its
own expenses, the fees of each arbitrator, the administrative costs of the
arbitration and the expenses, including reasonable attorneys' fees and costs,
incurred by the other party to the arbitration.

          (j) Shareholder Agent; Power of Attorney.

               (i) In the event that the Merger is approved by the Company
Shareholder, effective upon such vote, and without further act of the Company
Shareholder, Nai-Yu Pai shall be appointed as agent and attorney-in-fact (the
"Shareholder Agent") for the Company Shareholder, for and on its behalf, to give
and receive notices and communications, to authorize delivery to New Focus of
shares of New Focus Common Share from the Escrow Funds in satisfaction of claims
by New Focus, to object to such deliveries, to agree to, negotiate, enter into
settlements and compromises of, and demand arbitration and comply with orders of
courts and awards of arbitrators with respect to such claims, and to take all
actions necessary or appropriate in the judgment of the Shareholder Agent for
the accomplishment of the foregoing. Such agency may be changed by the Company
Shareholder from time to time upon not less than thirty (30) days prior written
notice to New Focus. No bond shall be required of the Shareholder Agent, and the
Shareholder Agent shall not receive compensation for his services. Notices or
communications to or from the Shareholder Agent shall constitute notice to or
from the Company Shareholder.

               (ii) The Shareholder Agent shall not incur any liability with
respect to any action taken or suffered by him or omitted hereunder as
Shareholder Agent while acting in good faith and in the exercise of reasonable
judgment. The Shareholder Agent may, in all questions arising hereunder, rely on
the advice of counsel and for anything done, omitted or suffered in good faith
by the Shareholder Agent based on such advice, the Shareholder Agent shall not
be liable to anyone. The Shareholder Agent undertakes to perform such duties and
only such duties as are specifically set forth in this Agreement and no implied
covenants or obligations shall be read into this Agreement against the
Shareholder Agent.

               (iii) The Shareholder Agent shall have reasonable access to
information about the Company and the reasonable assistance of the Company's
officers and employees for purposes of performing its duties and exercising its
rights hereunder, provided that the Shareholder Agent shall treat confidentially
and not disclose any nonpublic information from or about the Company to anyone
(except on a need to know basis to individuals who agree in writing to treat
such information confidentially).

          (k) Actions of the Shareholder Agent. A decision, act, consent or
instruction of the Shareholder Agent shall constitute a decision of the Company
Shareholder for whom a portion of the Escrow Amount otherwise issuable to it are
deposited in the Escrow Funds and shall be final, binding and conclusive upon
the Company Shareholder, and the Escrow Agent and New Focus may rely upon any
such decision, act, consent or instruction of the Shareholder Agent as being the
decision, act, consent or instruction of the Company Shareholder. The Escrow
Agent and New Focus are hereby relieved from any liability to any person for any
acts done by them in accordance with such decision, act, consent or instruction
of the Shareholder Agent.

          (l) Third-Party Claims. In the event New Focus becomes aware of a
third-party claim (a "Third Party Claim") which New Focus reasonably expects may
result in a demand against the General Escrow Fund, New Focus shall notify the
Shareholder Agent of such claim, and the Shareholder Agent, as representative
for the Company Shareholder, shall be entitled, at the Company


                                      -50-

<PAGE>   56

Shareholder's expense, to participate in any defense of such claim. New Focus
shall have the right in its sole discretion to settle any Third Party Claim;
provided, however, that if New Focus settles any Third Party Claim without the
Shareholder Agent's consent (which consent shall not be unreasonably withheld or
delayed), New Focus may not make a claim against the General Escrow Fund with
respect to the amount of Losses incurred by New Focus in such settlement. In the
event that the Shareholder Agent has consented to any such settlement, the
Shareholder Agent shall have no power or authority to object under any provision
of this Article 7 to the amount of any claim by New Focus against the General
Escrow Fund with respect to the amount of Losses incurred by New Focus in such
settlement.

          (m) Indemnification for Shareholder Agent. The Company Shareholder
shall, indemnify, defend and hold the Shareholder Agent harmless from and
against any Loss, damage, tax, liability and expense that may be incurred by the
Shareholder Agent arising out of or in connection with the acceptance or
administration of the Shareholder Agent's duties, except as caused by the
Shareholder Agent's gross negligence or willful misconduct, including the legal
costs and expenses of defending such Shareholder Agent against any claim or
liability in connection with the performance of the Shareholder Agent's duties.
The Shareholder Agent shall be entitled, but not limited, to such
indemnification from the Escrow prior to any distribution thereof to the Company
Shareholder, but after any distributions therefrom to New Focus.

          (n) Escrow Agent's Duties.

               (i) Limitation on Duties of Escrow Agent. The Escrow Agent shall
be obligated only for the performance of such duties as are specifically set
forth herein, and as set forth in any additional written escrow instructions
which the Escrow Agent may receive after the date of this Agreement which are
signed by an officer of New Focus and the Shareholder Agent, and may rely and
shall be protected in relying or refraining from acting on any instrument
reasonably believed to be genuine and to have been signed or presented by the
proper party or parties. The Escrow Agent shall not be liable for any act done
or omitted hereunder as Escrow Agent while acting in good faith and in the
exercise of reasonable judgment, and any act done or omitted pursuant to the
advice of counsel shall be conclusive evidence of such good faith.

               (ii) Compliance with Orders. The Escrow Agent is hereby expressly
authorized to comply with and obey Orders of any court of law or Governmental or
Regulatory Authority, notwithstanding any notices, warnings or other
communications from any party or any other person to the contrary. In case the
Escrow Agent obeys or complies with any such Order, the Escrow Agent shall not
be liable to any of the parties hereto or to any other person by reason of such
compliance, notwithstanding any such Order being subsequently reversed,
modified, annulled, set aside, vacated or found to have been entered without
jurisdiction or proper authority.

               (iii) Limitations on Liability of Escrow Agent. The Escrow Agent
shall not be liable in any respect on account of (A) the identity, authority or
rights of the parties executing or delivering or purporting to execute or

<PAGE>   57

               (iv) Good Faith of Escrow Agent. In performing any duties under
the Agreement, the Escrow Agent shall not be liable to any party for damages,
Losses, or expenses, except for gross negligence or willful misconduct on the
part of the Escrow Agent. The Escrow Agent shall not incur any such liability
for (A) any act or failure to act made or omitted in good faith, or (B) any
action taken or omitted in reliance upon any instrument, including any written
statement or affidavit provided for in this Agreement that the Escrow Agent
shall in good faith believe to be genuine, nor will the Escrow Agent be liable
or responsible for forgeries, fraud, impersonations or determining the scope of
any representative authority. In addition, the Escrow Agent may consult with
legal counsel in connection with the Escrow Agent's duties under this Agreement
and shall be fully protected in any act taken, suffered, or permitted by him,

Agent is not responsible for determining and verifying the authority of any
person acting or purporting to act on behalf of any party to this Agreement.

between the parties to this Agreement, or with any other party, concerning the
subject matter of this Agreement, its terms or conditions, the Escrow Agent will
not be required to determine the controversy or to take any action regarding it.

may wait for settlement of any such controversy by final appropriate legal
proceedings or other means as, in the Escrow Agent's discretion, the Escrow
Agent may be required, despite what may be set forth elsewhere in this
Agreement. In such event, the Escrow Agent will not be liable for any damages.
Furthermore, the Escrow Agent may at its option, file an action of interpleader
requiring the parties to answer and litigate any claims and rights among
themselves. The Escrow Agent is authorized to deposit with the clerk of the
court all documents and shares of New Focus Common Stock held in escrow, except
all costs, expenses, charges and reasonable attorney fees incurred by the Escrow
Agent due to the interpleader action and which the parties jointly and severally
agree to pay. Upon initiating such action, the Escrow Agent shall be fully
released and discharged of and from all obligations and liability imposed by the
terms of this Agreement.


               (vi) Indemnification of Escrow Agent. New Focus and its
successors and assigns agrees to indemnify and hold the Escrow Agent harmless
