(1) Based on the maximum number of shares to be issued in connection with the
    merger, calculated as the product obtained by multiplying (a) an exchange
    ratio of 3.1350 shares of the registrant's common stock for each share of
    Ortel common stock, par value $0.001 per share, by (b) 17,390,471, the sum
    of (i) the aggregate number of shares of Ortel common stock outstanding on
    February 28, 2000 (other than shares owned by Solara Acquisition Inc., a
    wholly owned subsidiary of the registrant, or the registrant or any of its
    subsidiaries) and (ii) the aggregate number of shares of Ortel common stock
    issuable pursuant to outstanding options prior to the date the merger is
    expected to be consummated.

(2) Estimated solely for the purpose of calculating the registration fee
    required by Section 6(b) of the Securities Act, and calculated pursuant to
    Rule 457(f) under the Securities Act. Pursuant to Rule 457(f)(1) under the
    Securities Act, the proposed maximum aggregate offering price of the
    registrant's common stock was calculated in accordance with Rule 457(c)
    under the Securities Act as: (a) 158.3125, the average of the high and low
    prices per share of Ortel common stock on February 23, 2000 as reported on
    The Nasdaq National Market, multiplied by (b) 17,390,471, the maximum number
    of shares of Ortel common stock computed as described in clause (b) of Note
    (1).

(3) No separate consideration will be received for the rights, which initially
    will trade together with the common stock.

Q:   WHY IS THE ORTEL BOARD OF DIRECTORS RECOMMENDING THAT I VOTE FOR ADOPTION
     OF THE MERGER AGREEMENT?


A:   In reaching its decision to approve the merger agreement and the merger and
     to recommend adoption of the merger agreement by Ortel stockholders, the
     Ortel board of directors consulted with Ortel management, as well as
     Ortel's financial and legal advisors, and considered the terms of the
     proposed merger agreement and the transactions contemplated by the merger
     agreement. In addition, the Ortel board of directors considered each of the
     items set forth on pages 23 to 25. Based on those consultations and
     considerations, the Ortel board of directors unanimously approved the
     merger agreement and the merger, and believes that the terms of the merger
     agreement and the merger are advisable and fair to, and in the best
     interests of, Ortel and its stockholders.

     as soon as possible so that your shares may be represented at the special
     meeting. If you sign and send in your proxy and do not indicate how you
     want to vote, we will count your proxy as a vote in favor of adoption of
     the merger agreement. IF YOU ABSTAIN FROM VOTING OR DO NOT VOTE YOUR SHARES

                                    GENERAL

WHAT YOU WILL RECEIVE IN THE MERGER

      In the merger, you will receive 3.1350 shares of Lucent common stock for
each share of Ortel common stock that you own. You will receive cash for any
fractional share of Lucent common stock that you would otherwise receive in the
merger.

OWNERSHIP OF LUCENT FOLLOWING THE MERGER


      Based on the number of outstanding shares of Ortel common stock on the
record date, we anticipate that Ortel stockholders will receive in the aggregate
approximately 40,953,025 shares of Lucent common stock in the merger. Based on
that number and on the number of outstanding shares of Lucent common stock on
the record date, following the merger former Ortel stockholders will own
approximately 1% of the outstanding shares of Lucent common stock.


CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
(PAGE 37)

      The merger is intended to qualify as a reorganization within the meaning
of the Internal Revenue Code of 1986. It is a condition to the completion of the
merger that Ortel receive an opinion from its counsel, Latham & Watkins, and
that Lucent receive an opinion from its counsel, Sidley & Austin, each stating
that the merger will qualify for United States federal income tax purposes as a
reorganization within the meaning of the Internal Revenue Code. If the merger
qualifies, unless you are subject to special tax treatment under the Internal
Revenue Code, you will not recognize gain or loss for United States federal
income tax purposes as a result of the exchange of your Ortel common stock for
Lucent common stock in the merger, except for any cash received in lieu of a
fractional share of Lucent common stock.

      TAX MATTERS ARE VERY COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGER TO
YOU WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR OWN
TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES OF THE MERGER TO
YOU.

merger agreement are advisable and fair to, and in the best interests of, Ortel
and its stockholders and unanimously recommends that stockholders vote "FOR" the

well as certain risks related to the merger, see pages 20 to 25 and page 14.


INTERESTS OF ORTEL'S DIRECTORS AND MANAGEMENT IN THE MERGER (PAGE 32)

      Ortel stockholders should note that a number of directors and officers of
Ortel have interests in the merger as directors or officers that are different
from, or in addition to, those of a stockholder. If the merger is completed,
certain indemnification arrangements for current directors and officers of Ortel
will be continued and it is expected that most of the current executive officers
of Ortel will be retained as employees of or consultants to Lucent. Ortel also
has agreed to pay up to $15 million to Stephen R. Rizzone and up to $4.5 million
to certain other Ortel employees if the merger is completed. In addition,
several of Ortel's officers may be entitled to severance payments under existing
employment agreements as a result of the merger. In addition, directors and
employees with stock options to acquire Ortel common stock will have these
options converted to stock options to acquire Lucent common stock, and stock
options held by directors and certain officers will become or under certain
circumstances may become fully vested as a result of the merger.

STOCK OPTION AGREEMENT (PAGE 49)

      Ortel has granted an option to
Lucent to purchase shares of Ortel common stock equal to approximately 19.9% of
the number of outstanding shares of Ortel common stock at a price per share of
$177.125 if certain events occur that entitle Lucent to receive the termination
fee under the merger agreement. The option agreement limits to $105 million the
total amount Lucent may receive from (1) the stock option and (2) any
termination fee payable by Ortel if the merger agreement is terminated.

NON-COMPETITION AND NON-DISCLOSURE AGREEMENTS (PAGE 49)

      As a condition to the merger, certain officers of Ortel must enter into
non-competition and non-disclosure agreements with Lucent and Ortel. Under these
agreements, each of these employees agrees with Lucent and Ortel that, for a
specified period, the employee will not, without the express written consent of
Lucent, compete with the activities currently conducted by Ortel.

REGULATORY MATTERS (PAGE 38)


      United States antitrust laws prohibit Lucent and Ortel from completing the
merger until after they have furnished certain information and materials to the
Antitrust Division of the Department of Justice and the Federal Trade Commission
and a required waiting period has ended. Lucent and Ortel each filed the
required notification and report forms with the Antitrust Division and the
Federal Trade Commission on February 25, 2000. Under the antitrust laws, the
merger may not be completed until after the expiration or early termination of
the applicable waiting period. The applicable waiting period expired on March
26, 2000. Lucent and Ortel have also made a joint filing with regulatory
authorities in Germany on March 24, 2000. The applicable waiting period expires
on April 24, 2000.


ACCOUNTING TREATMENT (PAGE 34)

      The merger will be accounted for under the "purchase" method of accounting
in accordance with generally accepted accounting principles. Lucent expects a
significant portion of the purchase price to be allocated to goodwill and other
intangible assets. The merger is also expected to result in a charge against
earnings for in-process research and development.

EXPENSES (PAGE 47)

      Lucent and Ortel will each pay its own expenses incidental to the
preparation of the merger agreement, the carrying out of the provisions of the
merger agreement and the completion of the merger whether or not the merger is
completed, except that Lucent and Ortel will share equally the costs of filing
with the Securities and Exchange Commission the registration statement of which
this proxy statement/prospectus is a part, printing and mailing this proxy
statement/ prospectus and the filing fees incurred in connection with obtaining
regulatory approval for the merger.

COMPARATIVE PER SHARE INFORMATION

     We have summarized below the per common share information for each of
Lucent and Ortel on a historical basis, for Lucent on a pro forma basis and for
Ortel on a pro forma equivalent basis. On February 11, 2000, Lucent's historical
results were restated to include the results of International Network Services
and Excel Switching Corporation, which merged with Lucent in transactions that
were each accounted for as a pooling of interests. All per share data has been
restated to account for Lucent's two-for-one stock split effective on April 1,
1999. Lucent's fiscal year ends on September 30 and Ortel's fiscal year ends on
April 30.

     The unaudited "pro forma Lucent" and the unaudited "pro forma equivalent --
Ortel" information assumes that the merger of Ortel and Lucent will be accounted
for as a purchase. The unaudited "pro forma Lucent" information is derived from
the historical financial information of Lucent at or for the three months ended
December 31, 1999 and at or for the year ended September 30, 1999, and the
financial information of Ortel at or for the three months ended January 30, 2000
and at or for the twelve months ended October 31, 1999, respectively, and
assumes the merger of Lucent and Ortel occurred at the beginning of the earliest
period presented. The Ortel financial information for the twelve months ended
October 31, 1999 is derived from the historical financial information of Ortel
for the year ended April 30, 1999 less the six-month period ended October 31,
1998 plus the six-month period ended October 31, 1999.

     The unaudited "pro forma Lucent" net income includes pro forma adjustments
for the amortization of goodwill and other intangible assets. These adjustments
are based on preliminary estimates; the final amounts of these adjustments may
vary. Ortel's results for the nine-month period ended January 30, 2000 and
Lucent's results for the three-month period ended December 31, 1999 may not be
indicative of results for the full year.

     "Pro forma Lucent" basic earnings per common share was calculated using the
weighted average number of Lucent common shares outstanding and adding the
weighted average number of Ortel common shares outstanding, assuming all Ortel
common stock was converted to Lucent common stock at the 3.1350 exchange ratio.

     "Pro forma Lucent" diluted earnings per share was calculated by dividing
"pro forma Lucent" net income by the sum of the weighted average number of "pro
forma Lucent" common shares outstanding plus all additional "pro forma Lucent"
common shares that would have been outstanding if potentially dilutive
securities or common stock equivalents had been issued.

     "Pro forma Lucent" book value per share was calculated by dividing the sum
of Lucent historical book value and the purchase price of Ortel (fair value of
the net assets acquired plus goodwill) by the "pro forma Lucent" common shares
outstanding during the period.

     The unaudited "pro forma equivalent -- Ortel" information was calculated by
multiplying the corresponding "pro forma Lucent" data by the 3.1350 exchange
ratio. This information shows how each share of Ortel common stock would have
participated
                                        8

in the net earnings, cash dividends and book value of Lucent if the merger had
been completed at the beginning of the earliest period presented. However, these
amounts do not necessarily reflect future per share levels of net earnings, cash
dividends or book value of Lucent.

SELECTED HISTORICAL FINANCIAL DATA -- LUCENT


     Lucent was spun off from AT&T Corp. in 1996. On February 1, 1996, AT&T
began transferring to Lucent the assets and liabilities relating to Lucent's
operations. Lucent's historical financial data for periods prior to that date
reflect the results of operations and the financial position of the business
that was transferred to Lucent from AT&T in the separation as if Lucent had been
a stand-alone entity and have been prepared using the historical basis in the
assets and liabilities and historical results of operations related to the
Lucent business. Lucent's historical financial data for periods prior to that
date also include an allocation of certain AT&T corporate headquarters assets,
liabilities and expenses related to the Lucent business. The calculation of
earnings (loss) per common share on a historical basis includes the retroactive
recognition to January 1, 1995 of the 524,624,894 shares on a pre-split basis,
or 2,098,499,576 shares on a post-split basis, owned by AT&T on April 10, 1996.


     Beginning September 30, 1996, Lucent changed its fiscal year end from
December 31 to September 30 and reported results for the nine-month transition
period ended September 30, 1996. All per share data has been restated to account
for Lucent's two-for-one stock splits effective on April 1, 1999 and on April 1,
1998. Lucent's results were restated to include the results of International
Network Services and Excel Switching Corporation, which merged with Lucent in
transactions that were each accounted for as a pooling of interests.

     Effective October 1, 1998, Lucent changed its method of accounting for
calculating the market-related value of plan assets used in determining the
expected return-on-asset component of annual net pension and post-retirement
benefit costs. As a result, Lucent recorded a one-time, after-tax gain from the
cumulative effect of the accounting change of $1,308 million (net of tax of $842
million), or $0.41 per diluted common share, for the first fiscal quarter of
1999. This accounting change also resulted in a reduction in benefit costs in
the year ended September 30, 1999 that increased income by $427 million ($260
million after-tax, or $0.08 per basic and diluted share) as compared with the
previous accounting method.

     The following selected historical financial data of Lucent at September 30,
1999 and 1998, and for each of the three years in the period ended September 30,
1999 are derived from audited historical financial statements incorporated by
reference in this proxy statement/prospectus. The selected historical financial
data of Lucent at September 30, 1997 and 1996 and December 31, 1995 and for each
of the years ended September 30, 1996 and December 31, 1995, and for the
nine-month period ended September 30, 1996, is derived from unaudited financial
statements not incorporated by reference in this proxy statement/prospectus,
and, in the opinion of Lucent's management, includes all necessary adjustments
for a fair presentation of that data in conformity with generally accepted
accounting principles.

     The selected historical financial data of Lucent at and for the three
months ended December 31, 1999 and December 31, 1998, is derived from unaudited
condensed financial statements incorporated by reference in this proxy
statement/prospectus and, in the opinion of Lucent's management, include all
necessary adjustments for a fair
                                       10

presentation of that data in conformity with generally accepted accounting
principles. Results for the three-month period ended December 31, 1999 may not
be indicative of the results for the full year.

                      RISK FACTORS RELATING TO THE MERGER

     In addition to the other information included and incorporated by reference
in this proxy statement/prospectus, Ortel stockholders should consider carefully
the matters described below in determining whether to adopt the merger
agreement.

     - THE EXCHANGE RATIO FOR LUCENT COMMON STOCK TO BE RECEIVED IN THE MERGER
       IS FIXED AND WILL NOT BE ADJUSTED IN THE EVENT OF ANY CHANGE IN STOCK
       PRICE.   Under the merger agreement, each share of Ortel common stock
       will be converted into the right to receive 3.1350 shares of Lucent
       common stock. This exchange ratio is fixed and will not be adjusted for
       any increase or decrease in the price of Lucent common stock or Ortel
       common stock. The prices of Lucent common stock and Ortel common stock at
       the closing of the merger may vary from their respective prices on the
       date of this proxy statement/prospectus and on the date of the special
       meeting. These prices may vary because of changes in the business,
       operations or prospects of Lucent or Ortel, the timing of the completion
       of the merger, the prospects of post-merger operations, general market
       and economic conditions and other factors. Because the date that the
       merger is completed may be later than the date of the special meeting,
       the prices of Lucent common stock and Ortel common stock on the date of
       the special meeting may not be indicative of their respective prices on
       the date the merger is completed. The Ortel board of directors urges
       Ortel stockholders to obtain current market quotations for Lucent common
       stock and Ortel common stock.

     - THE PRICE OF LUCENT COMMON STOCK MAY BE AFFECTED BY FACTORS DIFFERENT
       FROM THOSE AFFECTING THE PRICE OF ORTEL COMMON STOCK.   Upon completion
       of the merger, holders of Ortel common stock will become holders of
       Lucent common stock. Lucent's business differs from that of Ortel, and
       Lucent's results of operations, as well as the price of Lucent common
       stock, may be affected by factors different from those affecting Ortel's
       results of operations and the price of Ortel common stock. For a
       discussion of Lucent's and Ortel's businesses and certain factors to
       consider in connection with these businesses, see Lucent's Annual Report
       on Form 10-K for the fiscal year ended September 30, 1999, as amended,
       Lucent's Quarterly Report on Form 10-Q for the fiscal quarter ended
       December 31, 1999, Lucent's Form 8-K, filed February 11, 2000 to restate
       financial results for the merger of Lucent and INS and the merger of
       Lucent and Excel, Lucent's Form 8-K filed March 1, 2000 and Ortel's
       Annual Report on Form 10-K for the fiscal year ended April 30, 1999,
       which are incorporated by reference in this proxy statement/prospectus.

tax-free distribution of shares to

                                       15
<PAGE>   25


Lucent's stockholders to be completed by the close of Lucent's fourth fiscal
quarter of 2000, which ends on September 30. The spin-off is subject to several
conditions, including receipt of a favorable tax ruling and the absence of
events or developments that would have a material adverse impact on Lucent or
its stockholders. The new enterprise business will have approximately 34,000
employees worldwide and will operate independently from Lucent with its own
brand, board of directors, management and research and development
organizations. For additional information, please see Lucent's current report on
Form 8-K filed March 1, 2000.


MATERIAL CONTRACTS BETWEEN LUCENT AND ORTEL

                              THE SPECIAL MEETING

     We are furnishing this proxy statement/prospectus to stockholders of Ortel
as part of the solicitation of proxies by the Ortel board of directors for use
at the special meeting.

DATE, TIME AND PLACE


     The special meeting will be held at The Ritz-Carlton, Huntington Hotel &
Spa, 1401 South Oak Knoll Avenue, Pasadena, California 91106, at 9:00 a.m.,
local time, on April 27, 2000.


PURPOSE OF SPECIAL MEETING


     At the special meeting, holders of Ortel common stock will be asked to
adopt the merger agreement. The Ortel board of directors has determined that the
merger is advisable and fair to, and in the best interests of, Ortel
stockholders, has unanimously approved the merger agreement and the merger, and
unanimously recommends that Ortel stockholders vote "FOR" adoption of the merger
agreement.


RECORD DATE; STOCK ENTITLED TO VOTE; QUORUM


     Only holders of record of Ortel common stock at the close of business on
March 14, 2000, the record date, are entitled to notice of and to vote at the
special meeting. On the record date, 13,063,166 shares of Ortel common stock
were issued and outstanding and held by approximately 110 holders of record. A
quorum is present at the special meeting for purposes of the vote of the holders
of Ortel common stock if a majority of the shares of Ortel common stock which
are issued and outstanding and entitled to vote on the record date are
represented in person or by proxy. Shares of Ortel common stock represented at
the special meeting but not voting, including abstentions and broker non-votes,
will be treated as present at the special meeting for purposes of determining
the presence or absence of a quorum for the transaction of all business. If a
quorum is not present at the special meeting, it is expected that the meeting
will be adjourned or postponed to solicit additional proxies. Holders of record
of Ortel common stock on the record date are entitled to one vote per share of
common stock at the special meeting.


VOTES REQUIRED

     The affirmative vote of a majority of the shares of Ortel common stock is
required to adopt the merger agreement. IF YOU ABSTAIN FROM VOTING OR DO NOT
VOTE, EITHER IN PERSON OR BY PROXY, IT WILL HAVE THE EFFECT OF A VOTE AGAINST
ADOPTION OF THE MERGER AGREEMENT.

VOTING AGREEMENT


     On February 7, 2000, Sumitomo Osaka Cement entered into a voting agreement
with Lucent pursuant to which it has agreed to vote the Ortel common stock it
owns "FOR" adoption of the merger agreement. The voting agreement is attached as
Annex D.


                                       17
<PAGE>   27


On the record date, Sumitomo Osaka Cement owned and was entitled to vote
approximately 18.0% of the outstanding shares of Ortel common stock.



     On the record date, directors and executive officers of Ortel beneficially
owned approximately 9.3% of the outstanding shares of Ortel common stock. Each
of the directors and executive officers of Ortel has advised Ortel that he
intends to vote all shares of Ortel common stock over which he has or shares
voting control "FOR" adoption of the merger agreement.


VOTING OF PROXIES


     All shares represented by properly executed proxies received in time for
the special meeting will be voted at the special meeting in the manner specified
by the holders. PROPERLY EXECUTED PROXIES THAT DO NOT CONTAIN VOTING
INSTRUCTIONS WILL BE VOTED "FOR" ADOPTION OF THE MERGER AGREEMENT.


     Only shares voted for adoption of the merger agreement, including properly
executed proxies that do not contain voting instructions, will be counted as
favorable votes for the merger agreement. If you abstain from voting or do not
vote, either in person or by proxy, it will count as a vote against adoption of
the merger agreement. Brokers who hold shares of Ortel common stock in street
name for customers who are the beneficial owners of such shares may not give a
proxy to vote those customers' shares in the absence of specific instructions
from those customers. Those non-voted shares are referred to as broker non-votes
and count as votes against adoption of the merger agreement.

     Ortel does not expect that any matter other than the proposal to adopt the
merger agreement will be brought before the special meeting. If, however, the
Ortel board of directors properly presents other matters, the persons named as
proxies will vote on those other matters in accordance with their judgment. In
addition, the persons named as proxies may propose and vote for one or more
adjournments or postponements of the special meeting, including adjournments or
postponements to permit further solicitation of proxies. No proxy voted against
the proposal to adopt the merger agreement will be voted in favor of any
adjournment or postponement.

REVOCABILITY OF PROXIES

     The grant of a proxy on the enclosed form of proxy does not preclude you
from voting in person at the special meeting. You may revoke a proxy at any time
prior to its exercise by:

     - filing with the secretary of Ortel, before the proxy is voted at the
       special meeting, a duly executed written notice of revocation of proxy
       which is dated later than the proxy

     - before the proxy is voted at the special meeting, submitting a duly
       executed later dated proxy to the secretary of Ortel or

     - voting in person at the special meeting, although attendance at the
       special meeting will not itself constitute revocation of a proxy.
                                       18
<PAGE>   28

     Any written notice of revocation or subsequent proxy should be sent to
Ortel Corporation, 2015 West Chestnut Street, Alhambra, California 91803,
Attention: Secretary, or hand delivered to the Secretary of Ortel at or before
the taking of the vote at the special meeting.

SOLICITATION OF PROXIES

     Ortel will bear the cost of the solicitation of proxies from its
stockholders. In addition to solicitation by mail, the directors, officers and
employees of Ortel and its subsidiaries may solicit proxies from stockholders by
telephone or other electronic means or in person. Ortel has retained the
services of MacKenzie Partners to assist in the solicitation of proxies by
Ortel. Ortel will pay $6,000, plus reimbursement of some out-of-pocket expenses,
to MacKenzie Partners for its services. Ortel will cause brokerage houses and
other custodians, nominees and fiduciaries to forward solicitation materials to
the beneficial owners of stock held of record by those persons. Ortel will
reimburse any of these custodians, nominees and fiduciaries for their reasonable
out-of-pocket expenses in doing so.

     PLEASE DO NOT SEND STOCK CERTIFICATES WITH YOUR PROXY.   A transmittal form
with instructions for the exchange of Ortel common stock certificates will be
mailed to you as soon as practicable after completion of the merger.

                                   THE MERGER

     The following discussion summarizes the material terms of the merger, the
merger agreement and the stock option agreement. We urge stockholders to read
carefully the merger agreement and the stock option agreement which are attached
as Annexes A and B to this proxy statement/prospectus.

BACKGROUND TO THE MERGER

     At the meeting of the Ortel board of directors in September 1999 and again
in December 1999, the board discussed the ongoing consolidation in the
optoelectronic components industry and the risks and opportunities that such
consolidation presented for Ortel. The board discussed the benefits and risks of
remaining independent in a consolidating industry and the risks and benefits of
combining with a strategic partner. While, from time to time, Ortel had received
inquiries of interest from various companies about possible business
combinations, none of the inquiries had ever resulted in substantive
discussions.

     On December 9, 1999, Lucent and Ortel entered into a commercial agreement
pursuant to which Ortel agreed to supply Lucent with components for
incorporation into one of Lucent's products. In connection with the negotiation
of the commercial agreement, the management of the two companies discussed other
potential business opportunities.

     In late December 1999, Lucent management began considering a possible
business combination with Ortel.

     On January 5, 2000, a meeting was held among Terence Bentley, Director --
Corporate Development, Michael Bond, Business Development Vice President, Ettore
J. Coringrato, Manager of Optoelectronics, Microelectronics and Communications
Technologies, Daniel A. DiLeo, President of Optoelectronics, Microelectronics
and Communications Technologies, all of Lucent, and Stephen R. Rizzone, Chairman
of the Ortel board of directors, President and Chief Executive Officer, George
B. Holmes, Vice President -- Worldwide Sales and Jeffrey S. Rittichier, Vice
President -- Marketing, all of Ortel, to discuss a possible business combination
between the two companies.

     From January 7 through January 17, 2000, in a series of telephone
conferences, Mr. Bentley and Mr. Rizzone continued to discuss a possible
combination between the two companies, including a process for the exchange of
information about each company and the receipt of necessary internal approvals.
On January 10, 2000, Lucent and Ortel entered into a confidentiality agreement
for the exchange of information which contained customary terms and conditions.

     At a telephonic meeting of the Ortel board of directors on January 10,
2000, Mr. Rizzone informed the board of his conversations with the
representatives of Lucent as well as of his discussions with the representatives
of another company which had indicated an interest in a business combination
with Ortel. The board discussed in general the merits of a business combination
given the current business environment. The board also discussed whether it was
in the best interests of Ortel for management to

                                       20
<PAGE>   30

divert any of its attention from executing Ortel's strategic plan to pursue
discussions with Lucent or any other company. After discussion, the board
determined that it would be in Ortel's best interests for management to continue
its current discussions regarding the two possible business combinations. In
addition, the board authorized management to engage SoundView Technology Group,
Inc. as a financial advisor to Ortel (a) to solicit indications of interest in a
possible business combination from selected other companies and (b) to assist
Ortel in the current and any resulting discussions or negotiations.

     Based in part on conversations with SoundView and earlier contacts he had
with other companies, on January 12, 2000, Mr. Rizzone traveled to northern
California for separate meetings with executives of three companies which had
indicated they potentially would be interested in a business combination with
Ortel. Later in the week, representatives of two of these companies contacted
Mr. Rizzone and indicated that they had no current interest in pursuing a
business combination. Representatives of the third company, which Ortel had
previously had conversations with, exchanged information with and continued
discussions with Ortel until early February when that company indicated that it
was not willing to pursue a business combination on terms that Ortel believed
were at least comparable to those being negotiated with Lucent.

     On January 13, 2000, Ortel formally retained SoundView to provide financial
advisory services in connection with Ortel's interest in pursuing a business
combination.

     From January 18 through January 21, 2000, Mr. Bentley discussed with Mr.
Rizzone and Roger Hay, Vice President -- Finance and Chief Financial Officer of
Ortel, the exchange of information between the two companies.

     On January 19, 2000, Lucent obtained preliminary approval from the office
of the Chief Executive Officer to continue discussions with Ortel.

     On January 20, 2000, Mr. Rizzone, Mr. Hay, Mr. Bentley and Mr. Bond had a
telephonic meeting. During the meeting, Mr. Bentley and Mr. Bond informed Mr.
Rizzone and Mr. Hay of Lucent's further interest in pursuing a business
combination of the two companies. During the discussion, Lucent proposed various
principal terms of such a transaction, including:

     - Lucent's requirement that any transaction be an "at market" transaction

     - the anticipation that the transaction would be treated as a tax-free
       reorganization

     - Lucent's preference that the transaction be accounted for as a purchase
       and

     - Ortel's granting of a stock option to Lucent to acquire an amount of
       Ortel common stock equal to 19.9% of the outstanding common stock.

     On January 21, 2000, the Ortel board of directors held a telephonic meeting
at which Mr. Rizzone reviewed the progress of discussions since the previous
telephonic board meeting. After discussion, the board authorized Ortel
management to continue pursuing discussions of a business combination with
Lucent and to provide Lucent with more detailed information about Ortel.

                                       21
<PAGE>   31

     From January 24 through January 28, 2000, Mr. Bentley and Mr. Rizzone
discussed certain material terms of a possible business combination, including
the vesting of stock options held by senior management, certain compensation
payable to Mr. Rizzone upon completion of the business combination and certain
non-competition and non-disclosure agreements for certain Ortel officers.


     On January 24 and 25, 2000, representatives of Lucent, including Lucent's
financial and legal advisors, conducted due diligence at the offices of Latham &
Watkins, counsel to Ortel, in Costa Mesa, California regarding the businesses
and operations of Ortel.


     On January 25, 2000, the Ortel board of directors held a telephonic meeting
to discuss the status of the ongoing discussions. During the meeting, Mr.
Rizzone updated the board concerning the due diligence process and the
discussions that Ortel management had had with Lucent regarding the principal
terms of a transaction.

     On January 27, 2000, Mr. Bentley and Mr. Hay discussed certain accounting
and financial information relating to Lucent and Ortel.

     On January 29, 2000, representatives of Lucent and Ortel discussed the
terms of the proposed transaction and the findings from the due diligence
conducted by Lucent.

     On January 31, 2000, the Ortel board of directors held another telephonic
meeting to discuss the status of the ongoing discussions. Mr. Rizzone informed
the board that Lucent had reiterated its interest in pursuing a transaction at
the market value of Ortel common stock, as Lucent management indicated that it
considered the current market price of Ortel common stock to already reflect a
premium. Paul Mejean of SoundView indicated to the board that he believed that
Lucent would submit a final proposal by the end of the week.

     Mr. Bond and Mr. Bentley of Lucent, Mr. Rizzone of Ortel and Mr. Mejean of
SoundView held numerous telephone conferences from January 31 through February
5, 2000 to discuss the terms and conditions of a possible business combination.
On January 31, 2000, Lucent's legal advisors submitted a proposed merger
agreement to Ortel's legal counsel. From January 31 through February 6, 2000,
Ortel management and their financial and legal advisors conducted due diligence
concerning Lucent.

     On February 2, 2000, the Ortel board of directors held a special meeting in
Pasadena, California. During the meeting, Mr. Rizzone described the offer to
acquire Ortel submitted by Lucent and Ortel's legal counsel described the status
of the negotiation of the merger agreement. The offer reflected Lucent's
intention to pursue an "at market" transaction. After much discussion, the board
authorized management to continue negotiations but directed that the terms on
which the board could accept an "at market" offer would have to be consistent
with the exercise of its fiduciary duties to Ortel stockholders.

     On February 4, 2000, the Ortel board of directors again held a telephonic
meeting to discuss the potential transaction with Lucent. At the meeting, Mr.
Rizzone updated the board concerning the negotiations with Lucent. Ortel's legal
counsel reported on the negotiation of the proposed merger agreement.

                                       22
<PAGE>   32

     From February 4 through February 6, 2000, representatives of Lucent and
Ortel, together with their financial and legal advisors, held numerous
conference calls to discuss and negotiate the terms and conditions of the merger
agreement, the stock option agreement and other transaction related documents.

     On February 6, 2000 the Ortel board of directors held a special meeting in
Pasadena, California to discuss the final terms of Lucent's proposal to acquire
Ortel. Prior to the meeting, each board member received a draft copy of the
proposed merger agreement and certain publicly available financial information
about Lucent and the proposed merger. At the meeting, Ortel management and legal
and financial advisors of Ortel reviewed with the board:

     - the strategic rationale for, and financial analyses relating to, the
       proposed merger

     - the potential benefits and risks of the transaction with Lucent and

     - the principal terms of the merger agreement and related documents.

     In addition, at the meeting SoundView provided its opinion that the
exchange ratio was fair, from a financial point of view, to the Ortel
stockholders. Following lengthy discussion, the Ortel board of directors
determined that the proposed merger was advisable and unanimously approved the
merger agreement and stock option agreement, and unanimously resolved to
recommend that the Ortel stockholders adopt the merger agreement.

     On the morning of February 7, 2000, the Lucent board of directors met by
telephone conference call to consider the terms of the merger and the definitive
agreements, and, after deliberation, approved the merger agreement and the stock
option agreement with Ortel and the voting agreement with Sumitomo Osaka Cement.

     The merger agreement, the stock option agreement, the voting agreement
between Lucent and Sumitomo Osaka Cement, and the letter agreement between
Lucent and Ortel regarding senior management were signed by the parties on the
morning of February 7, 2000, and prior to the commencement of trading, Lucent
and Ortel issued a joint press release announcing the execution of the merger
agreement.

REASONS FOR THE MERGER

     In reaching its decision to approve the merger agreement and the merger and
to recommend adoption of the merger agreement by Ortel stockholders, the Ortel
board of directors consulted with Ortel management, as well as its financial and
legal advisors, and independently considered the proposed merger agreement and
the transactions contemplated by the merger agreement. In unanimously approving
the merger agreement and the merger, the Ortel board of directors considered a
number of factors, including all the following:

     - current industry, market and economic conditions

     - the ongoing consolidation in the telecommunications equipment sector
       generally

                                       23
<PAGE>   33

     - the belief that a business combination with Lucent presents improved
       business prospects as compared to remaining independent

     - the potential to expand Ortel's international presence and to accelerate
       the development of relationships with communication system suppliers in
       the data communications and telecommunications industries through
       Lucent's established relationships, sales and marketing resources and
       distribution channels

     - the potential to accelerate the development of Ortel's products in the
       future and to offer its customers more complete end-to-end solutions by
       leveraging Lucent's technology, expertise and products

     - the ability to expand Ortel's sales and marketing infrastructure by
       leveraging Lucent's extensive sales and marketing resources, which Ortel
       management believes will provide Ortel with opportunities to develop
       relationships with additional communication system suppliers

     - the ability to expand Ortel's customer base and reduce Ortel's reliance
       upon key customers

     - the complementary nature of Ortel's and Lucent's product offerings across
       a range of products

     - Ortel's business, assets, management, competitive position, operating
       performance, trading performance and prospects, including Ortel's
       prospects if Ortel were to continue as an independent company

     - Lucent's business, financial conditions, results of operations, assets,
       management, competitive position, operating performance, trading
       performance and prospects and

     - Lucent's financial condition after the transaction, including its market
       capitalization, revenues, profits and earnings per share.

     In the course of deliberations, the Ortel board of directors also
considered a number of additional factors relevant to the merger, including:

     - the possibility of strategic alternatives to the merger for enhancing
       long-term stockholder value, including soliciting offers from other
       companies

     - the exchange ratio

     - the market price of Ortel common stock over the last several years and
       the potential for an increase and decrease in the market price of Ortel
       common stock in the future

     - the market price of Lucent common stock over the last several years and
       the anticipated relative stability of Lucent common stock

     - the potential for improved trading liquidity for Ortel stockholders

                                       24

     - the opinion of SoundView that, as of February 6, 2000 and subject to the
       considerations and assumptions set forth in the opinion, the exchange
       ratio is fair to Ortel stockholders from a financial point of view


     - the terms and conditions of the merger agreement, including termination
       fees, the grant of a stock option to Lucent and closing conditions

     - the expected qualification of the merger as a tax-free reorganization
       under Section 368(a) of the Internal Revenue Code

     - the transaction being accounted for as a purchase rather than as a
       pooling of interests which will result in Lucent incurring substantial
       charges to earnings over the next several years

     - the impact of the merger on Ortel's customers, suppliers and employees

     - the likelihood of the merger being approved by the appropriate regulatory
       authorities

     - the likelihood that the merger would be completed and

     - the effect of the public announcement of the merger on the market price
       of Ortel common stock and Lucent common stock.

     The Ortel board of directors also identified and considered a number of
potentially negative factors in its deliberations concerning the merger,
including:

     - the risk that, despite Ortel's and Lucent's efforts after the merger, the
       combined company may lose key personnel

     - the risk that a significant number of Ortel's customers and suppliers
       might cease doing business with Ortel after the merger

     - the difficulty of managing operations in the different geographic
       locations in which Ortel and Lucent operate and

     - the risk that the potential benefits of the merger might not be fully
       realized.

     The Ortel board of directors determined that these risks were unlikely to
occur, that Ortel and Lucent could avoid or mitigate these and other risks, and
that, overall, these risks were outweighed by the potential benefits of the
merger.

     The above discussion of the factors considered by the Ortel board of
directors in making its decision is not intended to be exhaustive. In view of
the variety of factors considered in connection with its evaluation of the
merger agreement and the merger, the Ortel board of directors did not find it
practicable to, and did not, quantify or otherwise assign relative weight to the
specific factors considered in reaching its determination. In addition,
individual members of the Ortel board of directors may have given different
weight to different factors.


RECOMMENDATION OF THE ORTEL BOARD OF DIRECTORS



     After careful consideration, the Ortel board of directors unanimously
determined that the terms of the merger agreement and the merger are advisable
and fair to, and in


                                       25
<PAGE>   35


the best interests of, Ortel and its stockholders and has unanimously approved
the merger agreement and the merger. The Ortel board of directors unanimously
recommends that the Ortel stockholders vote "FOR" the adoption of the merger
agreement.



FAIRNESS OPINION OF SOUNDVIEW TECHNOLOGY GROUP, INC.


     SoundView Technology Group, Inc. was retained by the Ortel board of
directors to render an opinion as to whether the exchange ratio is fair, from a
financial point of view, to the holders of the outstanding shares of Ortel
common stock.

     At a meeting of the Ortel board of directors on February 6, 2000, SoundView
delivered its written opinion to the Ortel board of directors to the effect
that, as of such date, based upon the facts and circumstances as they existed at
that time, and subject to certain assumptions made, matters considered and
limits of review set forth therein, the exchange ratio was fair, from a
financial point of view, to the holders of the outstanding shares of Ortel
common stock.

     The full text of the written opinion of SoundView, dated February 6, 2000,
including, among other things, the assumptions made, matters considered, and the
scope and limitations of the review undertaken and procedures followed by
SoundView in rendering its opinion, is included in Annex C to this proxy
statement/prospectus and is incorporated herein by reference. The summary of the
opinion of SoundView set forth below does not purport to be a complete
description of the analysis performed by SoundView in connection with rendering
the opinion and is qualified in its entirety by reference to the full text of
the opinion. Ortel stockholders are urged to read carefully the written opinion
of SoundView in its entirety.

     SoundView's opinion is directed only to the fairness of the exchange ratio,
from a financial point of view, to the holders of the outstanding shares of
Ortel common stock. SoundView's opinion was expressly intended for the benefit
and use of the Ortel board of directors in its consideration of the merger and
is not intended to be and does not constitute a recommendation to the Ortel
board of directors or any Ortel stockholder as to how such stockholder should
vote with respect to the proposed merger.

     In connection with rendering its opinion, SoundView, among other things:

     - reviewed the draft merger agreement and the specific terms of the merger
       set forth therein, and assumed that the merger agreement would not vary
       in any regard that is material to SoundView's analysis

     - reviewed Ortel's financial and operating information for the three-year
       period ended April 30, 1999 and the six-month period ended October 31,
       1999

     - reviewed Lucent's financial and operating information for the three-year
       period ended December 31, 1999

     - reviewed certain financial and operating information regarding the
       businesses, operations and prospects of Ortel, including forecasts and
       projections, provided to SoundView by Ortel management

                                       26
<PAGE>   36

     - reviewed certain financial and operating information regarding the
       businesses, operations and prospects of Lucent, including forecasts and
       projections, published and disseminated by stock market research analysts
       who follow Lucent (internal financial forecasts and projections prepared
       by Lucent were not made available for SoundView's review)

     - reviewed certain publicly available financial information concerning
       certain other companies SoundView deemed to be reasonably similar to
       Ortel and Lucent and the trading markets for these companies' securities

     - reviewed the financial terms of the merger and compared them with the
       financial terms, to the extent publicly available, of certain recent
       mergers and acquisitions that SoundView deemed relevant and

     - performed such other analyses, examinations and procedures, reviewed such
       other agreements and documents, and considered such other factors as
       SoundView deemed, in its sole judgment, to be necessary, appropriate or
       relevant to render its opinion.

     SoundView also took into account its assessment of general economic, market
and financial conditions and its experience in similar transactions, as well as
its experience in securities valuation in general. SoundView's opinion is
necessarily based on economic, market, financial and other conditions as in
effect on, and the information available to it as of February 6, 2000.
Subsequent developments may affect SoundView's opinion, and SoundView does not
have any obligation to update, revise or reaffirm its opinion.

     In arriving at its opinion, SoundView did not make, obtain or assume any
responsibility for any independent evaluation or appraisal of the properties and
facilities or of the assets and liabilities (contingent or otherwise) of either
Ortel or Lucent. SoundView relied upon the accuracy and completeness of the
financial and other information supplied to or otherwise used by it in arriving
at its opinion, and did not attempt independently to verify, or undertake any
obligation to verify, such information. SoundView also relied upon the
assurances of the management of Ortel that it was not aware of any facts that
would make such information inaccurate or misleading. In addition SoundView
assumed that the forecasts and projections provided to it by Ortel represented
the best currently available estimates and judgments of Ortel's management as to
the future financial condition and results of operations of Ortel and assumed
that such forecasts and projections were reasonably prepared based on such
currently available estimates and judgments. SoundView assumed no responsibility
for and expressed no view as to such forecasts and projections or the
assumptions on which they were based.

     SoundView did not express any view as to the price at which Lucent common
stock will trade prior to or subsequent to the closing of the merger. Its
opinion did not constitute a recommendation of the merger over any other
alternative transactions which may have been available to Ortel and did not
address the underlying business decision of the Ortel board of directors to
proceed with or effect the merger.

                                       27

     In accordance with customary investment banking practice, SoundView
employed generally accepted valuation methods in reaching its opinion. The
following is a summary of the material financial analyses utilized by SoundView
in connection with rendering its opinion.

   COMPARABLE PUBLICLY TRADED COMPANIES ANALYSES

     ORTEL.   Using publicly available information, SoundView compared certain
financial, market and operating information of selected publicly traded photonic
component manufacturers that were, in SoundView's judgment, similar to Ortel.
The companies analyzed by SoundView in connection with this analysis were:

     - Finisar Corporation

     - Harmonic, Inc.

     - JDS Uniphase Corporation and

     - SDL, Inc.

     For each of the selected companies, SoundView calculated a multiple of
market capitalization to projected calendar 2000 and 2001 revenues. SoundView
also calculated the 2000 and 2001 revenue growth rate for each of the selected
companies. The results of this analysis were as follows:

     LUCENT.   Using publicly available information, SoundView analyzed certain
financial, market and operating information of selected publicly traded
telecommunications companies that were, in SoundView's judgment, similar to
Lucent. The companies analyzed by SoundView in connection with this analysis
were:

     COMPARABLE TRANSACTIONS ANALYSIS.   Using publicly available information,
SoundView analyzed the purchase prices and multiples paid in seven selected
merger and acquisition transactions announced between January 28, 1999 and
January 17, 2000 involving photonic component manufacturers that, in SoundView's
judgment, were generally comparable to the business of Ortel. The transactions
analyzed by SoundView in connection with this analysis were:

<TABLE>

          ACQUIROR                       TARGET

    Uniphase Corporation             JDS Fitel Inc.
</TABLE>

     For each of the target companies in the selected transactions, SoundView
calculated a multiple of equity value to last twelve months, or LTM, revenue and
LTM net income, respectively, and a multiple of equity value to one-year forward
revenues and net income, respectively, as of the date the transaction was
announced. The results of this analysis were as follows:

(1) Equity value for this transaction was computed based on the closing price of
    Ortel common stock on February 4, 2000 and the average price of Lucent
    common stock during the three-trading day period preceding February 4, 2000.
    Equity value for each of the comparable transactions was computed based on
    the price per share

                                       29

    company's outstanding number of fully-diluted shares at the announcement
    date calculated using the treasury stock method.

(2) Equity value divided by projected revenue for the one-year period after the
    applicable announcement date.

(3) Equity value divided by projected net income for the one-year period after
    the applicable announcement date.

     SoundView noted that no company or transaction used in the foregoing
analysis is directly comparable to Ortel or the merger. SoundView also noted
that none of these transactions took place under market conditions or
competitive conditions or circumstances that, as of the date of SoundView's
opinion, were directly comparable to the merger. Accordingly, SoundView did not
rely solely on the mathematical results of the analysis, but also made
qualitative judgments concerning the differences in financial and operating
characteristics of these companies and transactions and other factors and issues
that could affect the value of the companies or transactions to which Ortel or
the merger are being compared.

     CONTRIBUTION ANALYSIS.   SoundView analyzed Ortel's contribution to the
projected operating performance of Lucent. SoundView calculated the percentage
of Ortel's contribution to Lucent's pro forma projected 2000 and 2001 revenue,
operating income and net income, respectively. The results of this analysis were
as follows:

<TABLE>

</TABLE>

     Based on the exchange ratio and the number of outstanding shares of Lucent
common stock on a fully-diluted basis as of February 4, 2000, the holders of the
shares of Ortel common stock will, upon consummation of the merger, own
approximately 1.4% of the outstanding shares of Lucent common stock on a
fully-diluted basis giving effect to the merger.

     IMPLIED EXCHANGE RATIO ANALYSIS.   SoundView calculated implied exchange
ratios using an implied market capitalization of Ortel. SoundView applied the
multiples of projected 2000 revenue and net income, respectively, from the
comparable transactions analysis to Ortel's projected 2000 revenue and net
income. SoundView also applied the multiples of projected 2000 revenue and net
income, respectively, from the comparable companies analysis for Ortel.
SoundView then adjusted the multiples of projected 2000 revenue and net income,
respectively, from the comparable companies analysis for Ortel's 2000 revenue
growth rate. SoundView calculated a range of implied exchange ratios based on
the average closing price of Lucent common stock during the three trading days
preceding February 4, 2000. Based on calendar 2000 revenue multiples, the
analysis implied an exchange ratio range of 1.67 to 4.11. Based on calendar 2000
net income multiples, the analysis implied an exchange ratio range of 0.93 to
2.07.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. While the
foregoing summary describes all material analyses and factors considered by
SoundView in rendering its opinion, the summary does not purport to be a
complete description of SoundView's analyses. SoundView believes that its
analyses and summaries should be considered as a whole, and that selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying SoundView's opinion. In arriving at its fairness determination,
SoundView considered the results of all of its analyses as a whole and did not
attribute particular weight to any analysis or factor. As noted above, no
company or transaction used in any of the foregoing analyses as a comparison is
directly comparable to Ortel or Lucent or the contemplated transaction.

     These analyses were prepared solely for purposes of SoundView's providing
its opinion to the Ortel board of directors as to the fairness from a financial
point of view of the exchange ratio to the holders of the outstanding shares of
Ortel common stock and do not purport to be appraisals or necessarily reflect
the prices at which businesses or securities actually may be sold. Analyses
based upon forecasts of future results are not necessarily indicative of actual
future results, which may be significantly more or less favorable than suggested
by such analyses. Because such analyses are inherently subject to uncertainty,
being based upon numerous factors or events beyond the control of the parties or
their respective advisors, none of Ortel, Lucent, SoundView nor any other person
assumes responsibility if future results are materially different from those
forecast. As described above, SoundView's opinion to the Ortel board of
directors was one of many factors taken into consideration by the board of
directors of Ortel in making its determination to approve the merger agreement.

     SoundView is a nationally recognized investment banking firm. As part of
its investment banking services, SoundView is frequently engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of securities, private placements and valuations for corporate and
other purposes. SoundView was retained by the Ortel board of directors to act as
its financial advisor in connection with the merger based upon SoundView's
experience as a financial advisor in mergers and acquisitions, as well as
SoundView's familiarity with the photonic component and telecommunications
industries.

     Except as described above, SoundView has not rendered material financial
advisory or investment banking services to Ortel or to Lucent during the last
three years. In the ordinary course of its business, SoundView may actively
trade the securities of Lucent or Ortel for its own account and for the accounts
of its customers and, accordingly, may at any time hold a long or short position
in such securities.

     Pursuant to a letter agreement dated January 13, 2000, as amended, Ortel
engaged SoundView to render its opinion in connection with the merger. Pursuant
to the terms of the letter agreement, Ortel has agreed to pay SoundView a fee
equal to approximately $3 million, of which $350,000 was paid upon delivery of
the opinion. Ortel has also

                                       31
<PAGE>   41

agreed to reimburse SoundView for its reasonable out-of-pocket expenses,
including the fees and disbursements of its counsel, and to indemnify SoundView
against certain liabilities, including liabilities under the federal securities
laws. The Securities and Exchange Commission has taken the position that such
indemnification under the federal securities laws may not be enforceable if it
is found to be against public policy.

INTERESTS OF ORTEL'S DIRECTORS AND MANAGEMENT IN THE MERGER

     In considering the recommendation of the Ortel board of directors in favor
of the merger, you should be aware that certain directors and executive officers
of Ortel have interests in the merger that are different from, or in addition
to, the interests of Ortel stockholders. These interests relate to or arise
from, among other things:

     - the continued indemnification of current directors and officers of Ortel
       pursuant to the merger agreement

     - the retention of certain officers of Ortel as employees or consultants of
       Lucent

     - directors and employees with stock options to acquire Ortel common stock
       will have these options converted to stock options to acquire Lucent
       common stock pursuant to the merger agreement and options held by Ortel's
       directors and certain executive officers will become or under certain
       circumstances may become fully vested as a result of the merger

     - certain officers are parties to employment agreements that provide for
       severance payments and the acceleration of stock options if they are
       terminated by Ortel or resign for "good reason" (including a substantial
       reduction in responsibilities) following a "change in control," such as
       the merger, and

     - a letter agreement among Ortel, Lucent and Stephen R. Rizzone relating to
       special payments to Mr. Rizzone and other Ortel employees upon completion
       of the merger.

     These interests are described below, and except as described below those
persons have, to the knowledge of Lucent and Ortel, no material interest in the
merger apart from those of stockholders generally. The Ortel board of directors
was aware of, and considered the interests of, its directors and executive
officers in approving the merger agreement and the merger.

     INDEMNIFICATION AND INSURANCE.   The merger agreement provides that all
rights of indemnification from liabilities existing in favor of the current and
former directors or officers of Ortel and its subsidiaries as provided in
Ortel's respective certificate of incorporation and by-laws and certain
indemnification agreements of Ortel will be assumed by the surviving corporation
in the merger, and will continue in full force and effect in accordance with
their terms after the merger. Lucent will maintain for six years after the
merger directors' and officers' liability insurance for acts or omissions which
occur prior to the merger for those directors and officers who were, as of the
date of the merger agreement, covered by Ortel's directors' and officers'
liability insurance policy, on terms no less advantageous than those in effect
on the date of the merger agreement.

                                       32
<PAGE>   42

Lucent's obligation to provide this insurance coverage is subject to a cap of
200% of the current annual premium paid by Ortel for its existing insurance
coverage. If Lucent cannot maintain the existing or equivalent insurance
coverage without exceeding the 200% cap, Lucent is required to maintain only
that amount of insurance coverage which can be obtained by paying an annual
premium equal to the 200% cap.

     ORTEL EXECUTIVE OFFICERS.   Most of Ortel's current executive officers are
expected to be retained as employees of or consultants to Lucent after the
merger.


     The merger agreement provides that all stock options to acquire Ortel
common stock will be assumed by Lucent. As a result, each stock option to
acquire Ortel common stock held by Ortel's directors and executive officers will
be converted to a stock option to acquire Lucent common stock. In addition, each
of the stock options held by Ortel's directors, including Mr. Rizzone, will
become fully vested and exercisable upon completion of the merger. In the
aggregate, options covering approximately 810,027 shares of Ortel common stock
held by Ortel's directors and executive officers will become fully vested and
exercisable as a result of the merger. In addition, the stock options held by
some of Ortel's other officers will also become fully vested and exercisable
under certain circumstances as a result of the merger as set forth in agreements
they have with Ortel.


     Some of Ortel's executive officers may also be entitled to severance
payments if they are terminated by Ortel or resign for "good reason" following a
"change in control," such as the merger.

     EMPLOYEE BENEFITS.   Lucent has agreed to provide employee benefit plans,
programs and arrangements to those individuals who will continue to be employees
of Ortel after the merger that are the same as those made generally available to
non-represented employees of Lucent hired after December 31, 1999. These
benefits will be made available as soon as practicable after the merger. Until
these benefits are made available, Lucent has agreed that it will provide the
same benefits that were provided to employees of Ortel on February 7, 2000.

     With respect to each Lucent benefit in which Ortel employees subsequently
participate, for purposes of determining vesting and entitlement to benefits,
including for severance benefits and vacation entitlement (but not for accrual
of pension benefits), service with Ortel will be treated as service with Lucent.
This service will also apply for purposes of satisfying any waiting periods,
evidence of insurability requirements, or the application of any pre-existing
condition limitations. Each Lucent benefit plan will waive pre-existing
condition limitations to the extent waived under the applicable Ortel benefit
plan. Ortel's employees will receive credit under each Lucent benefit plan for
amounts paid under a corresponding Ortel benefit plan during the same benefit
period for purposes of applying deductibles, co-payments and out-of-pocket
maximums.

     SPECIAL PAYMENTS.   Ortel has agreed to pay Mr. Rizzone up to $15 million
if the merger is completed. Of this amount, Ortel will pay up to $9 million to
Mr. Rizzone upon completion of the merger as consideration for Mr. Rizzone
entering into a non-competition and non-disclosure agreement having a term of
five years and $6 million

                                       33
<PAGE>   43

pursuant to an agreement having a term of three years related to Mr. Rizzone's
continued employment with Lucent and, if such employment is terminated, for Mr.
Rizzone's consulting services.


     In addition, Ortel has agreed to pay an aggregate of $4.5 million upon the
completion of the merger to employees of Ortel designated by Mr. Rizzone. Ortel
management anticipates entering into separate letter agreements with some of
these employees before the closing of the merger. The letter agreement also
provides that in the event Nadav Bar-Chaim, Hank Blauvelt, Sandra Caraveo, John
Dessel, George Holmes, George Pontiakos or Jeff Rittichier (each of whom is
currently an officer of Ortel) are terminated by Ortel other than for cause
within one year of the completion of the merger, all unvested options held by
the terminated employee at that time will become fully exercisable.


     STOCK OPTIONS.   Under the merger agreement, at the effective time of the
merger, Lucent will assume each stock option plan of Ortel and all stock options
and agreements granted under those plans and agreements to acquire shares of
Ortel common stock. Each stock option outstanding at the effective time will be
converted into a stock option to acquire Lucent common stock on the same terms
and conditions. The number of shares of Lucent common stock to be subject to any
option will be equal to the number of shares of Ortel common stock subject to
that Ortel option multiplied by the 3.1350 exchange ratio and rounded down to
the nearest whole share. The exercise price per share of Lucent common stock
under any option will be equal to the exercise price per share of Ortel common
stock subject to that Ortel option divided by the 3.1350 exchange ratio, rounded
to the nearest one hundredth of a cent. As of February 7, 2000, the number of
shares of Ortel common stock reserved for issuance pursuant to outstanding Ortel
stock options under the plans was 4,203,226.

     In the case of any assumed stock option that is an incentive stock option
under Section 422 of the Internal Revenue Code, the option price and the number
of shares of Lucent common stock purchasable pursuant to that option will be
further adjusted, if necessary, to preserve the status of the option as an
incentive stock option. Prior to the merger, Lucent will take all necessary
actions to assume the Ortel stock option plans and agreements, and list the
shares issuable under those stock options on the New York Stock Exchange. As
soon as practicable following the effective time of the merger, Lucent will
prepare and file with the Securities and Exchange Commission an appropriate
registration statement registering the shares of Lucent common stock subject to
the assumed Ortel stock options. The registration statement will be kept
effective (and the current status of the prospectus or prospectuses required by
that registration statement shall be maintained) for so long as any assumed
Ortel options remain outstanding.

ACCOUNTING TREATMENT

     The merger will be accounted for under the "purchase" method of accounting
in accordance with generally accepted accounting principles. Lucent expects a
significant portion of the purchase price to be allocated to goodwill and other
intangible assets. The

                                       34
<PAGE>   44

merger is also expected to result in a charge against Lucent's earnings for
in-process research and development.

FORM OF THE MERGER

     Subject to the terms and conditions of the merger agreement and in
accordance with Delaware law, at the effective time of the merger, Solara
Acquisition Inc., a wholly owned subsidiary of Lucent, will merge with and into
Ortel. Ortel will survive the merger and become a wholly owned subsidiary of
Lucent. Ortel will continue operations under the name "Ortel Corporation."

MERGER CONSIDERATION

     At the effective time of the merger, each outstanding share of Ortel common
stock will be converted into the right to receive 3.1350 shares of Lucent common
stock, except that treasury stock and stock held by Solara Acquisition or Lucent
will be canceled. Stockholders will receive cash for any fractional share that
they would otherwise receive in the merger. As of the effective time of the
merger, all shares of Ortel common stock will no longer be outstanding and will
automatically be canceled. At that time, each holder of a certificate
representing shares of Ortel common stock will cease to have any rights as a
stockholder except the right to receive Lucent common stock and the right to
receive cash for any fractional share of Lucent common stock. The exchange ratio
was determined through arm's-length negotiations between Lucent and Ortel.

     Based on the number of outstanding shares of Lucent common stock and Ortel
common stock as of the record date, the holders of Ortel common stock
immediately prior to the merger would own approximately 1% of the outstanding
shares of Lucent common stock immediately after the merger. After the merger,
each outstanding option to purchase Ortel common stock will be converted into an
option to purchase shares of Lucent common stock.

CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES

     The conversion of Ortel common stock into the right to receive Lucent
common stock will occur automatically at the effective time of the merger. As
soon as practicable after the merger, The Bank of New York, the exchange agent,
will send a transmittal letter to each former Ortel stockholder. The transmittal
letter will contain instructions for obtaining shares of Lucent common stock in
exchange for shares of Ortel common stock. PLEASE DO NOT SEND STOCK CERTIFICATES
WITH THE ENCLOSED PROXY.

     After the merger, each certificate that previously represented shares of
Ortel common stock will represent only the right to receive the Lucent common
stock into which those shares were converted in the merger and the right to
receive cash for any fractional share of Lucent common stock as described below.

     Until holders of certificates previously representing Ortel common stock
have surrendered those certificates to the exchange agent for exchange, holders
will not receive dividends or distributions on the Lucent common stock into
which those shares have been converted with a record date after the merger, and
will not receive cash for
                                       35
<PAGE>   45

any fractional share of Lucent common stock. When holders surrender those
certificates, they will receive any unpaid dividends and any cash for any
fractional share of Lucent common stock without interest.

     In the event of a transfer of ownership of Ortel common stock which is not
registered in the records of Ortel's transfer agent, a certificate representing
the proper number of shares of Lucent common stock may be issued to a person
other than the person in whose name the certificate so surrendered is registered
if:

     - that certificate is properly endorsed and otherwise is in proper form for
       transfer and

     - the person requesting the issuance (1) pays to the exchange agent any
       transfer or other taxes resulting from the issuance of shares of Lucent
       common stock in a name other than that on the surrendered certificate, or
       (2) establishes to the satisfaction of the exchange agent that any tax
       has been paid or is not applicable.

     All shares of Lucent common stock issued upon conversion of shares of Ortel
common stock, including any cash paid for any fractional share of Lucent common
stock, will be issued in full satisfaction of all rights relating to those
shares of Ortel common stock.

     No fractional share of Lucent common stock will be issued to any Ortel
stockholder upon surrender for exchange of certificates previously representing
Ortel common stock. In lieu of any fractional share, the stockholder will
receive cash equal to the product obtained by multiplying (1) the closing price
for a share of Lucent common stock on the New York Stock Exchange Composite
Transactions Tape on the date immediately preceding the date on which the merger
is completed by (2) the fractional share to which the stockholder would
otherwise be entitled.

EFFECTIVE TIME OF THE MERGER

     The merger will become effective upon the filing of a certificate of merger
with the Secretary of State of the State of Delaware, or at such later time as
stated in the certificate of merger or agreed upon by Lucent and Ortel. The
filing of the certificate of merger will occur at the time of the closing of the
merger.

STOCK EXCHANGE LISTING OF LUCENT COMMON STOCK

     It is a condition to the completion of the merger that Lucent common stock
issued to Ortel stockholders in the merger be authorized for listing on the New
York Stock Exchange, subject to official notice of issuance.

DELISTING AND DEREGISTRATION OF ORTEL COMMON STOCK

     If the merger is completed, Ortel common stock will be delisted from The
Nasdaq National Market and will be deregistered under the Securities Exchange
Act of 1934.

CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER


     The following summary of the material United States federal income tax
consequences of the merger to the holders of Ortel common stock who hold their
Ortel common stock as a capital asset is based upon current provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), currently applicable
Treasury regulations and judicial and administrative rulings and decisions as of
the date hereof. The following summary is not binding on the Internal Revenue
Service (the "IRS"), and no rulings have been or will be sought from the IRS
regarding any matters relating to the merger. In addition, legislative, judicial
or administrative changes may be forthcoming that could alter or modify the
statements set forth herein, possibly on a retroactive basis. The summary does
not purport to deal with all aspects of the federal income taxation that may be
relevant to particular holders of Ortel common stock in light of their
individual circumstances, nor with certain types of holders who are subject to
special treatment under the federal income tax laws (e.g., tax-exempt
organizations; insurance companies; financial institutions; broker-dealers;
persons who hold such stock as part of a hedge, appreciated financial position,
straddle or conversion transaction; holders whose functional currency is not the
U.S. dollar; holders who acquired their stock pursuant to the exercise of
employee stock options or otherwise as compensation; and holders who are neither
citizens nor residents of the United States, or that are foreign corporations,
foreign partnerships or foreign estates or trusts for United States federal
income tax purposes). Also, the summary assumes that each holder holds his or
her shares of Ortel common stock as capital assets. Finally, no foreign, state
or local tax considerations are addressed herein. CONSEQUENTLY, EACH HOLDER OF
ORTEL COMMON STOCK IS STRONGLY URGED TO CONSULT HIS OR HER OWN TAX ADVISOR
REGARDING THE TAX CONSEQUENCES OF THE MERGER IN LIGHT OF EACH SUCH HOLDER'S
PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICABILITY AND EFFECT OF FEDERAL,
STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS.


     Completion of the merger is conditioned upon, among other things, the
receipt by Ortel and Lucent of tax opinions of Latham & Watkins and Sidley &
Austin, respectively, each dated as of the closing date, to the effect that the
merger will qualify for United States federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code. These opinions will be based on customary assumptions and representations
made by Ortel, the acquisition subsidiary, and Lucent. An opinion of counsel
represents counsel's best legal judgment and is not binding on the IRS or any
court.

     CONSEQUENCES OF THE MERGER.   Provided that the merger qualifies as a
reorganization, and based on the above assumptions and qualifications, the
merger will generally result in the following federal income tax consequences:

     - no gain or loss will be recognized by Ortel or Lucent solely as a result
       of the merger

     - no gain or loss will be recognized by Ortel's stockholders who exchange
       their Ortel common stock solely for Lucent common stock (except to the
       extent of cash received in lieu of fractional shares)

                                       37
<PAGE>   47

     - the holding period of Lucent common stock received will include the
       holding period of shares of Ortel common stock surrendered in the merger

     - the aggregate tax basis of Lucent common stock received by Ortel
       stockholders who exchange all of their Ortel common stock for Lucent
       common stock in the merger will be the same as the aggregate tax basis of
       Ortel common stock surrendered in the merger (reduced by any portion of
       such tax basis allocable to a fractional share of Lucent common stock for
       which cash is received) and

     - cash payments received by Ortel stockholders in lieu of a fractional
       share of Lucent common stock will be treated as capital gain or loss
       measured by the difference, if any, between the cash payment received and
       the portion of the tax basis in the shares of Ortel common stock
       allocable to the fractional share; this gain or loss will be long-term
       capital gain or loss if the holder's holding period in the Ortel common
       stock exchanged for the fractional share of Lucent common stock is more
       than one year at the time the merger is completed.

     BACKUP WITHHOLDING.   Backup withholding at the rate of 31% may apply with
respect to certain cash payments received by an Ortel stockholder in connection
with the merger unless either:

     - the recipient is a corporation or comes within certain other exempt
       categories and, when required, demonstrates this fact or

     - the recipient provides a correct taxpayer identification number,
       certifies as to no loss of exemption from backup withholding and
       otherwise complies with applicable requirements of the backup withholding
       rules.

     An Ortel stockholder who does not provide Lucent with his correct taxpayer
identification number may be subject to penalties imposed by the IRS. Any
amounts withheld under the backup withholding rules may be allowed as a refund
or a credit against the holder's federal income tax liability, provided that the
required information is furnished to the IRS.

REGULATORY MATTERS


     Under the Hart-Scott-Rodino Antitrust Improvements Act and related rules,
certain transactions, including the merger, may not be completed unless certain
waiting period requirements have been satisfied. Lucent and Ortel each filed a
Notification and Report Form with the Antitrust Division of the Department of
Justice and the Federal Trade Commission on February 25, 2000. The applicable
waiting period expired on March 26, 2000. At any time before or after the
effective time of the merger, the Antitrust Division, the Federal Trade
Commission or others could take action under the antitrust laws, including
seeking to prevent the merger, to rescind the merger or to conditionally approve
the merger upon the divestiture of substantial assets of Lucent or Ortel. Lucent
and Ortel have also made a joint filing with regulatory authorities in Germany
on March 24, 2000. The applicable waiting period expires on April 24, 2000.
There can be no assurance that a challenge to the merger on antitrust grounds
will not be made or, if made, that it would not be successful.


                                       38
<PAGE>   48

APPRAISAL RIGHTS

     Under Delaware corporate law, holders of Ortel common stock are not
entitled to appraisal rights in connection with the merger because, on the
record date, Ortel common stock was designated and quoted for trading on The
Nasdaq National Market and will be converted into shares of Lucent common stock,
which at the effective time of the merger will be listed on the New York Stock
Exchange.

RESALE OF LUCENT COMMON STOCK

     Lucent common stock issued in the merger will not be subject to any
restrictions on transfer arising under the Securities Act of 1933, except for
shares issued to any Ortel stockholder who may be deemed to be an "affiliate" of
Ortel for purposes of paragraphs (c) and (d) of Rule 145 under the Securities
Act. An affiliate of Ortel is any individual or entity that directly or
indirectly through one or more intermediaries controls, is controlled by or is
under common control with, Ortel or Lucent. It is expected that each affiliate
will agree not to transfer any Lucent common stock received in the merger unless
(1) the disposition is made in conformity with the provisions of Rule 145 under
the Securities Act, (2) the disposition has been registered under the Securities
Act, or (3) in the opinion of counsel reasonably acceptable to Lucent, the
disposition is otherwise exempt from registration under the Securities Act. The
merger agreement requires Ortel to use its reasonable best efforts to cause its
affiliates to enter into these agreements and conditions Lucent's obligation to
effect the merger on the receipt of these agreements. This proxy
statement/prospectus does not cover resales of Lucent common stock received by
any person upon completion of the merger, and no person is authorized to make
any use of this proxy statement/prospectus in connection with any resale.

                              THE MERGER AGREEMENT

     The following description summarizes the material provisions of the merger
agreement. We urge stockholders to read carefully the merger agreement, which is
attached as Annex A to this proxy statement/prospectus.


CONDITIONS TO THE MERGER


     Each party's obligation to complete the merger is subject to the
satisfaction or waiver of various conditions which include, in addition to other
customary closing conditions, all the following:

     - holders of a majority of the outstanding shares of Ortel common stock
       must adopt the merger agreement

     - the waiting period and any extension thereof applicable to the merger
       under United States antitrust laws must expire or be terminated

     - no judgment, order, decree, statute, law, ordinance, rule or regulation
       entered, enacted, enforced, promulgated or issued by any court or other
       governmental entity of competent jurisdiction or other legal restraint or
       prohibition being in

                                       39
<PAGE>   49

       effect, and no suit, action or proceeding by any governmental entity
       being pending that (1) would prevent the consummation of the merger or
       (2) otherwise would be reasonably likely to have a material adverse
       effect, as described below, on Lucent or Ortel; provided, that each of
       the parties will have used its reasonable best efforts (i) to prevent the
       entry of any legal restraint or prohibition and (ii) to appeal as
       promptly as possible any legal restraint or prohibition that may be
       entered

     - Lucent's registration statement on Form S-4, of which this proxy
       statement/prospectus forms a part, must have become effective under the
       Securities Act and must not be the subject of any stop order or
       proceedings seeking a stop order

     - the shares of Lucent common stock issuable to Ortel in the merger must be
       authorized for listing on the New York Stock Exchange, subject to
       official notice of issuance

       the various obligations and complied with the various conditions required
       by the merger agreement

     - the representations and warranties of each party set forth in the merger
       agreement must be true and correct as of the date of the merger agreement
       and as of the date on which the merger is to be completed as if made at
       and as of the date on which the merger is to be completed, except to the
       extent expressly made as of an earlier date, in which case as of such
       date, except where the failure of such representations and warranties to
       be true and correct, without giving effect to any included limitation as
       to "materially" or "material adverse effect," does not have, and could
       not reasonably be expected to have, individually or in the aggregate, a
       material adverse effect on the party

     - in the case of Lucent only, the rights issued pursuant to Ortel's rights
       agreement may not have become nonredeemable, exercisable, distributable
       or triggered

     - Ortel must receive from Latham & Watkins, and Lucent must receive from
       Sidley & Austin, on the date on which the registration statement is
       declared effective by the Securities and Exchange Commission and on the
       date on which the merger is to be completed an opinion in each case dated
       as of those dates, to the effect that on the basis of certain facts,
       representations and assumptions set forth in the opinions, the merger
       will be treated for United States federal income tax purposes as a
       reorganization with the meaning of Section 368(a) of the Internal Revenue
       Code

     - officers of Lucent and Ortel each signing and delivering representation
       letters relating to certain tax matters and

     - in the case of Lucent only, certain officers of Ortel must enter into
       non-competition and non-disclosure agreements with Ortel and Lucent, and
       those agreements must be in full force and effect.

                                       40
<PAGE>   50

     The merger agreement defines a "material adverse effect" when used in
connection with Lucent or Ortel as any condition or event that:

     - has a material adverse effect on the assets, business, financial
       condition or results of operations of Lucent or Ortel, as applicable, in
       each case, taken as a whole with its subsidiaries, other than any
       condition or event

         (1) relating to the economy in general

         (2) relating to the industries in which that party operates in general

         (3) arising out of or resulting from actions contemplated by the
             parties in connection with, or attributable to, the announcement of

         (4) in the case of Ortel, litigation commenced or threatened against

             merger agreement

       obligations under the merger agreement or the stock option agreement or

     - prevents or materially delays the consummation of the transactions
       contemplated by the merger agreement.

NO SOLICITATION

     The merger agreement provides that Ortel will not, and will not authorize
or permit any of its directors, officers or employees, or any investment banker,
financial advisor, attorney, accountant or other representative retained by it
or any of its subsidiaries to, directly or indirectly through another person:

     - solicit, initiate or encourage, including by way of furnishing
       information, or take any other action to facilitate, any inquiries or the
       making of any proposal that is or may reasonably be expected to lead to a
       takeover proposal, as described below, or

     - participate in any discussions or negotiations regarding any takeover
       proposal;

provided that if, at any time prior to the date of the special meeting, the
Ortel board of directors determines in good faith, after consultation with
outside counsel, that it is necessary to do so in order to comply with its
fiduciary duties to Ortel stockholders under applicable law, Ortel and its
representatives, in response to a superior proposal, as described below, which
was not solicited by Ortel or which did not otherwise result from a breach of
the merger agreement, subject to Ortel (1) providing Lucent with prior written
notice of Ortel's decision to enter into the negotiations, and (2) orally and in
writing promptly advising Lucent of the material terms and conditions of the
takeover proposal and the identity of the person making the takeover proposal,
Ortel may:

     - furnish under a customary confidentiality agreement information about
       Ortel and its subsidiaries to any person making a superior proposal and

     - participate in discussions or negotiations regarding that superior
       proposal.

                                       41
<PAGE>   51

     The merger agreement provides that:

     - the term "takeover proposal" means any inquiry, proposal or offer from
       any person relating to any direct or indirect acquisition or purchase of
       15% or more of the assets of Ortel and its subsidiaries, taken as a
       whole, or 15% or more of any class or series of equity securities of
       Ortel or any of its subsidiaries, any tender offer or exchange offer that
       if completed would result in any person beneficially owning 15% or more
       of any class or series of equity securities of Ortel or any of its
       subsidiaries, or any merger, consolidation, business combination,
       recapitalization, liquidation, dissolution or similar transaction
       involving Ortel or any of its subsidiaries and


     - the term "superior proposal" means any proposal made by a third party to
       acquire, directly or indirectly, for consideration consisting of cash
       and/or securities, more than 50% of the combined voting power of the
       shares of Ortel common stock then outstanding or all or substantially all
       the assets of Ortel on terms that the Ortel board of directors determines
       in its good faith judgment, based on the advice of a financial advisor of
       nationally recognized reputation, to be more favorable to the Ortel
       stockholders than the merger and for which financing, to the extent
       required, is then committed or which, in the good faith judgment of the
       Ortel board of directors, is reasonably capable of being obtained.


     Neither the Ortel board of directors nor any committee of the board of
directors will:

     - withdraw or modify, or propose publicly to withdraw or modify, in a
       manner adverse to Lucent, the approval or recommendation by the Ortel
       board of directors or such committee of the merger or the merger
       agreement

     - approve or recommend, or propose publicly to approve or recommend, any
       takeover proposal or

     - approve or recommend, or propose to approve or recommend, or execute or
       enter into any letter of intent, agreement in principle, acquisition
       agreement, option agreement or other similar agreement related to any
       takeover proposal, other than any such agreement entered into
       concurrently with a termination as described in the next sentence in
       order to facilitate such action.

Notwithstanding the foregoing, in response to a superior proposal received prior
to the date of the special meeting which was not solicited by Ortel and which
did not otherwise result from a breach of the provisions of the merger agreement
described above, if the Ortel board of directors determines in good faith, after
consultation with outside counsel, that it is necessary to do so in order to
comply with its fiduciary duties to the Ortel stockholders under applicable law,
the Ortel board of directors may terminate the merger agreement and enter into a
definitive agreement regarding the superior proposal, but only at a time prior
to the special meeting and that is after the tenth business day following
Lucent's receipt of written notice advising Lucent that the board of directors
is prepared to accept a superior proposal. Ortel must pay a fee in the amount of
$90 million to

Lucent upon termination. See "-- Termination of the Merger Agreement" and
"-- Termination Fees."


TERMINATION OF THE MERGER AGREEMENT


     The merger agreement may be terminated at any time before the effective
time of the merger, whether before or after adoption of the merger agreement by
the Ortel stockholders:

     - by mutual agreement of Lucent and Ortel

     - by Lucent or Ortel, if the merger has not been completed by December 31,
       2000; provided, that this right to terminate the merger agreement will
       not be available to a party whose failure to perform any of its
       obligations under the merger agreement has been the cause of, or resulted
       in, the failure of the merger to be completed by that date

     - by Lucent or Ortel, if any court of competent jurisdiction in the United
       States or other United States governmental authority issues an order,
       decree, ruling or takes any other action restraining, enjoining or
       otherwise prohibiting the merger and that order, decree, ruling or other
       action has become final and nonappealable

     - by Lucent or Ortel if holders of a majority of the shares of Ortel common
       stock do not adopt the merger agreement at an Ortel stockholders meeting
       or any adjournment or postponement of that meeting

     - by Lucent, if Ortel has materially breached its obligations under the
       merger agreement, unless the breach is cured within 30 calendar days
       after notice to Ortel

     - by Ortel, if Lucent has materially breached its obligations under the
       merger agreement, unless the breach is cured within 30 calendar days
       after notice to Lucent

     - by Ortel, at any time prior to the date of the special meeting of
       stockholders, in response to a superior proposal which was not solicited
       by Ortel and which did not otherwise result from a breach of the
       provisions of the merger agreement, if Ortel has complied with certain
       notice requirements and paid the termination fee or

     - by Lucent, if Ortel or any of its directors or officers participated in
       discussions or negotiations with third parties regarding certain takeover
       proposals or furnished information to third parties in breach of the
       merger agreement.

TERMINATION FEES


     Under certain circumstances, if the merger agreement is terminated, Ortel
must pay Lucent a termination fee of $90 million. Ortel must pay Lucent the
termination fee if:

     - Ortel stockholders receive a takeover proposal, a takeover proposal
       otherwise becomes publicly known or anyone publicly announces its
       intention to make a takeover proposal, and thereafter Lucent or Ortel
       terminates the merger agreement because either (1) the merger is not
       completed by December 31, 2000 or (2) the Ortel stockholders have not
       adopted the merger agreement at an Ortel stockholders meeting, and within
       nine months of the termination Ortel or any of its subsidiaries enters
       into any definitive agreement with respect to, or consummates, any
       takeover proposal

     - Ortel terminates the merger agreement because before the date of the
       special meeting Ortel receives an unsolicited proposal by a third party
       to acquire Ortel on terms determined by the Ortel board of directors to
       be more favorable to the Ortel stockholders than the terms of the merger
       with Lucent or

     - Lucent terminates the merger agreement because Ortel or any of its
       directors or officers participates in discussions or negotiations with
       third parties regarding certain takeover proposals or furnishes
       information to third parties in breach of the merger agreement.

     The merger agreement further provides that if Ortel fails to pay the
termination fee when due and, in order to obtain payment of the fee, Lucent
commences a suit which results in a judgment against Ortel for the fee, Ortel
must pay the costs and expenses, including attorneys' fees and expenses, in
connection with any action taken to collect payment, together with interest on
the amount of the fee.


CONDUCT OF BUSINESS PENDING THE MERGER


     Pursuant to the merger agreement, Ortel has agreed that, until the closing
of the merger, it will, and cause its subsidiaries to:

     - maintain its existence in good standing

     - maintain the general character of its business and properties and conduct
       its business in the ordinary and usual manner consistent with past
       practices, except as expressly permitted by the merger agreement

     - maintain business and accounting records consistent with past practices
       and

     - use its reasonable best efforts to preserve its business intact, to keep
       available to Ortel the services of its present officers and employees and
       to preserve for Ortel and each of its subsidiaries the goodwill of its
       suppliers, customers and others having material business relations with
       Ortel or the subsidiary.

INDEMNIFICATION AND INSURANCE



     The merger agreement provides that all rights of indemnification from
liabilities existing in favor of the current and former directors or officers of
Ortel and its subsidiaries as provided in Ortel's certificate of incorporation
and by-laws and in certain indemnification agreements of Ortel will be assumed
by the surviving corporation in the merger and will continue in full force and
effect in accordance with their terms after the merger. Lucent must maintain for
six years after the merger the directors' and officers' liability insurance for
acts or omissions which occur prior to the effective time of the merger for
those directors and officers who were, as of the date of the merger agreement,
covered by Ortel's directors' and officers' liability insurance policy, on terms
no less advantageous than those in effect on the date of the merger agreement.
Lucent's obligation to provide this insurance coverage is subject to a cap of
200% of the current annual premium paid by Ortel for its existing insurance
coverage. If Lucent cannot

                                       48
<PAGE>   58

maintain the existing or equivalent insurance coverage without exceeding the
200% cap, Lucent is required to obtain only that amount of insurance coverage
which can be obtained by paying an annual premium equal to the 200% cap.


AMENDMENTS TO ORTEL'S CERTIFICATE OF INCORPORATION



     As of the effective time of the merger, the Ortel certificate of
incorporation will be amended to be substantially identical to the certificate
of incorporation of Solara Acquisition immediately prior to the merger. For a
summary of certain provisions of the current Ortel certificate of incorporation
and the associated rights of Ortel stockholders, see "Comparison of Rights of
Common Stockholders of Lucent and Ortel" on page 54.



     AMENDMENTS TO THE ORTEL BY-LAWS.   The merger agreement provides that the
by-laws of Solara Acquisition, as in effect immediately prior to the merger,
will be the by-laws of the surviving corporation following the merger. For a
summary of certain provisions of the current Ortel by-laws and the associated
rights of Ortel stockholders, see "Comparison of Rights of Common Stockholders
of Lucent and Ortel" on page 54.


     NON-COMPETITION AND NON-DISCLOSURE AGREEMENTS.   As a condition to the
merger, each of Stephen R. Rizzone, George M. Pontiakos, Nadav Bar-Chaim,
Jeffrey S. Rittichier and George B. Holmes must enter into non-competition and
non-disclosure agreements with Ortel. Each of these officers has agreed with
Lucent and Ortel that, for a specified period, the employee will not directly or
indirectly, compete with the activities currently conducted by Ortel without the
express written consent of Lucent. The non-competition period for each
stockholder generally will end two years from the date of the merger, with the
exception of Stephen R. Rizzone, whose period will end five years from the date
of the non-competition and non-disclosure agreement.


                           THE STOCK OPTION AGREEMENT


     The following description summarizes the material provisions of the stock
option agreement. We urge stockholders to read carefully the stock option
agreement, which is attached as Annex B to this proxy statement/prospectus.


GENERAL



     Immediately following the execution and delivery of the merger agreement,
Lucent and Ortel entered into a stock option agreement under which Ortel granted
Lucent an option to purchase up to 2,550,041 shares of Ortel common stock, or
that number of shares of Ortel common stock equal to 19.9% of the then
outstanding shares of Ortel common stock, in each case, without giving effect to
shares of Ortel common stock subject to or issued under the option, at a
purchase price of $177.125 per share.



EXERCISE OF THE OPTION



     Except as described below, Lucent may exercise the option with respect to
any or all the option shares at any time or times after the occurrence of any
event unconditionally entitling Lucent to receive the termination fee under the
merger


                                       49
<PAGE>   59

agreement. The right to purchase shares under the stock option agreement will
expire at earlier to occur of the effective time of the merger and 15 months
after the occurrence of the event entitling Lucent to receive the termination
fee.

     Lucent may exercise the option with respect to all or a portion of the
option shares by delivering to Ortel an exercise notice specifying the number of
shares Lucent wishes to purchase, the denominations of certificates for those
shares and the closing date. Any purchase of the option shares is subject to
applicable laws and regulations, including approval under the Hart-Scott-Rodino
Antitrust Improvements Act and obtaining any other necessary regulatory
approvals.

     If Lucent receives notice that a regulatory approval will not be granted or
has not been obtained within six months of the date of the exercise notice,
Lucent may exercise its right to cancel the option with respect to a certain
number of option shares (up to the number of option shares for which regulatory
approval will not be granted or has not been obtained) in exchange for cash. The
amount of cash will be equal to that number of shares of Ortel common stock
multiplied by the difference between:

     - the average closing price on The Nasdaq National Market (or, if not
       listed on The Nasdaq National Market, as reported on any other national
       securities exchange or national securities quotation system on which
       Ortel common stock is listed or quoted, as reported in The Wall Street
       Journal (Northeast edition), or, if not reported thereby, any other
       authoritative source) of shares of Ortel common stock for the 10 trading
       days commencing on the 12th trading day immediately preceding the option
       closing date and

     - the purchase price per share.


ADJUSTMENT TO NUMBER AND TYPE OF SHARES


     The number and type of securities subject to the option and the purchase
price will be adjusted for any change in Ortel common stock by reason of a stock
dividend, split-up, merger, recapitalization, combination, exchange of shares or
similar transaction, so that Lucent will receive, upon exercise of the option,
the number and type of securities that Lucent would have received if the option
had been exercised immediately prior to the occurrence of that event, or the
record date of that event. The number of shares of Ortel common stock subject to
the option will also be adjusted in the event Ortel issues additional shares of
common stock, so that, after that issuance, the number of shares of Ortel common
stock subject to the option represents 19.9% of the shares of Ortel common stock
then issued and outstanding, without giving effect to shares subject to or
issued under the option.

     If Ortel enters into an agreement:

     - to consolidate with or merge into any person other than Lucent or one of
       its subsidiaries and Ortel will not be the surviving corporation

     - to permit any person other than Lucent or one of its subsidiaries to
       merge into Ortel and Ortel will be the surviving corporation, but the
       shares of Ortel common stock outstanding immediately before the merger
       will be exchanged for other

                                       50
<PAGE>   60

securities or property, or the shares of Ortel common stock outstanding
immediately prior to the merger will, after the merger, represent less than 50%
of the outstanding voting securities of the merged entity or

     - to sell or otherwise transfer all or substantially all its assets to any
       person other than Lucent or one of its subsidiaries

then that agreement will provide that the option will, upon the completion of
that transaction, be converted into, or exchanged for, an option with identical
terms appropriately adjusted to acquire the number and class of shares or other
securities or property Lucent would have received for Ortel common stock if the
option had been exercised immediately prior to that consolidation, merger, sale
or transfer, or the record date of that event.


LIMIT ON TOTAL PROFIT OF LUCENT


     The stock option agreement provides that in no event will Lucent's total
profit from the option plus any termination fee paid to Lucent under the merger
agreement exceed $105 million and, if Lucent's total profit would otherwise
exceed that amount, Lucent, at its discretion, is required to do one or any
combination of the following:

     - reduce the number of shares of Ortel common stock subject to the option

     - deliver to Ortel for cancellation shares of Ortel common stock previously
       purchased by Lucent or

     - pay cash to Ortel

so that Lucent's total profit from the option plus the termination fee pursuant
to the merger agreement so paid to Lucent does not exceed $105 million after
taking into account the foregoing actions.

     In addition, the stock option agreement provides that the option may not be
exercised by Lucent for a number of option shares that would result in a
"notional total profit" which, together with the termination fee payable to
Lucent pursuant to the merger agreement, would exceed $105 million. The stock
option agreement defines "notional total profit" as total profit from the option
assuming that the option shares were sold for cash at the closing market price
on The Nasdaq National Market (or, if not listed on The Nasdaq National Market,
as reported on any other national securities exchange or national securities
quotation system on which Ortel common stock is listed or quoted) for Ortel
common stock as of the close of business on the preceding trading day, less
customary brokerage commissions.


REGISTRATION RIGHTS AND LISTING


     Lucent has certain rights to require registration under the securities laws
by Ortel of any shares purchased under the option if necessary for Lucent to be
able to sell those shares and to require the listing of those shares on The
Nasdaq National Market or other national securities exchange.

                                       51
<PAGE>   61


ASSIGNABILITY; TRANSFERS


     The stock option agreement may not be assigned or delegated by Lucent or
Ortel without the prior written consent of the other. The shares subject to the
option may not be sold, assigned, transferred or otherwise disposed of except in
an underwritten public offering or to a purchaser or transferee who would not,
immediately after that sale, assignment, transfer or disposal, beneficially own
more than 3.0% of the outstanding voting power of Ortel. However, Lucent may
sell any of the shares it receives upon exercise of the option if the sale is
made in connection with a tender or exchange offer that has been approved or
recommended by a majority of the Ortel board of directors, which majority
includes a majority of directors who were directors as of the date of the stock
option agreement.


EFFECT OF STOCK OPTION AGREEMENT


     The stock option agreement is intended to increase the likelihood that the
merger will be completed on the terms set forth in the merger agreement.
Consequently, certain aspects of the stock option agreement may discourage
persons who might now or prior to the merger be interested in acquiring all of
or a significant interest in Ortel from considering or proposing an acquisition,

                      DESCRIPTION OF LUCENT CAPITAL STOCK


     The following summary of the capital stock of Lucent is subject in all
respects to applicable Delaware law, Lucent's certificate of incorporation and
by-laws and Lucent's rights agreement. See "Comparison of Rights of Common
Stockholders of Lucent and Ortel" on page 54.


     The total authorized shares of capital stock of Lucent consist of (1) 10
billion shares of common stock, $.01 par value per share, and (2) 250 million
shares of preferred stock, $1.00 par value per share. At the close of business
on January 31, 2000, approximately 3.2 billion shares of Lucent common stock
were issued and outstanding and no shares of Lucent preferred stock were issued
and outstanding.

     The Lucent board of directors is authorized to provide for the issuance
from time to time of Lucent preferred stock in series and, as to each series, to
fix the designation, the dividend rate and the preferences, if any, which
dividends on each series will have compared to any other class or series of
capital stock of Lucent, the voting rights, if any, the voluntary and
involuntary liquidation prices, the conversion or exchange privileges, if any,
applicable to each series and the redemption price or prices and the other terms
of redemption, if any, applicable to each series. Cumulative dividends, dividend
preferences and conversion, exchange and redemption provisions, to the extent
that some or all of these features may be present when shares of Lucent
preferred stock are issued, could have an adverse effect on the availability of
earnings for distribution to the holders of Lucent common stock or for other
corporate purposes.

                  COMPARISON OF RIGHTS OF COMMON STOCKHOLDERS
                              OF LUCENT AND ORTEL

     The rights of Lucent and Ortel stockholders are currently governed by the
Delaware General Corporation Law, and the respective certificates of
incorporation and by-laws of Lucent and Ortel. Upon completion of the merger,
the rights of Ortel stockholders who become stockholders of Lucent in the merger
will be governed by the Delaware General Corporation Law, Lucent's certificate
of incorporation and Lucent's by-laws.

     The following description summarizes the material differences that may
affect the rights of stockholders of Lucent and Ortel but does not purport to be
a complete statement of all those differences, or a complete description of the
specific provisions referred to in this summary. The identification of specific
differences is not intended to indicate that other equally or more significant
differences do not exist. Stockholders should read carefully the relevant
provisions of the Delaware General Corporation Law, Lucent's certificate of
incorporation and by-laws and Ortel's certificate of incorporation and by-laws.

CAPITALIZATION

     LUCENT.   Lucent's authorized capital stock is described above under
"Description of Lucent Capital Stock."

                                       54
<PAGE>   64


     ORTEL.   The total authorized shares of capital stock of Ortel consist of
(1) 25,000,000 shares of common stock, $.001 par value per share, and (2)
5,000,000 shares of preferred stock, $.001 par value per share. On the record
date, there were 13,063,166 shares of Ortel common stock outstanding and no
shares of Ortel preferred stock were issued and outstanding.


     The Ortel board of directors is authorized to issue up to 5,000,000 shares
of undesignated preferred stock, to determine the powers, preferences and rights
and the qualifications, limitations or restrictions granted to or imposed upon
any unissued series of undesignated preferred stock and to fix the number of
shares constituting any series and the designation of such series, without any
further vote or action by the Ortel stockholders. The Ortel board of directors
can issue preferred stock with voting, liquidation, dividend and other rights
superior to the rights of the Ortel common stock. Furthermore, such Ortel
preferred stock may have other rights, including economic rights, senior to the
Ortel common stock, and as a result, the issuance of such preferred stock could
cause a decrease in the market value of the Ortel common stock.

VOTING RIGHTS

     LUCENT.   Each holder of Lucent common stock is entitled to one vote for
each share held of record and may not cumulate votes for the election of
directors.

     ORTEL.   Each holder of Ortel common stock is entitled to one vote for each
share held of record and may not cumulate votes for the election of directors.

NUMBER, ELECTION, VACANCY AND REMOVAL OF DIRECTORS

     LUCENT.   Lucent's board of directors has seven members. Lucent's
certificate of incorporation provides that the Lucent board of directors will
consist of at least three directors and that the number of directors may be
changed from time to time by a resolution adopted by a majority of the total
number of directors which Lucent would have if there were no vacancies. As
permitted under the Delaware General Corporation Law, Lucent's certificate of
incorporation also provides that the Lucent board of directors consists of three
classes of directors. The directors in each class serve on the Lucent board of
directors for approximately three years each. Due to the retirement of two
directors from the Lucent board, one class of directors currently consists of a
single director.

     Lucent's certificate of incorporation and by-laws provide that if there is
a vacancy on the Lucent board of directors or if the number of directors is
increased, those vacancies will be filled by the affirmative vote of a majority
of the remaining directors then in office, even though less than a quorum, and
not by the stockholders. A director elected to fill a vacancy or newly created
directorship will serve until the next succeeding annual meeting of stockholders
following his election by the directors, and if elected by the stockholders at
such meeting, will serve for the remainder of the full term of the class of
directors in which the vacancy occurred or the new directorship was created and
until that director's successor will have been duly elected and qualified. No
decrease in the number of directors will shorten the term of any incumbent
director.

                                       55
<PAGE>   65

     Under Lucent's certificate of incorporation, any director may be removed
from office only for cause by the affirmative vote of the holders of at least a
majority of the voting power of all shares of Lucent common stock entitled to
vote generally in the election of directors then outstanding, voting together as
a single class.

     ORTEL.   The Ortel board of directors has eight members. Ortel's
certificate of incorporation provides that the number of directors shall be
fixed from time to time by or pursuant to Ortel's by-laws. Ortel's by-laws
provide that the Ortel board of directors consists of at least seven and no more
than eleven directors and that the exact number of directors be determined by
resolution of the board of directors. As permitted under the Delaware General
Corporation Law, Ortel's certificate of incorporation also provides that the
Ortel board of directors consists of three classes of directors, with the
directors in each class serving on the Ortel board of directors for
approximately three years each and the term of office of one class expiring each
year.

     Ortel's certificate of incorporation and by-laws provide that vacancies and
newly created directorships resulting from an increase in the authorized number
of directors will be filled solely by the affirmative vote of a majority of the
directors then in office, even though less than a quorum, or by a sole remaining
director, and the directors so chosen hold office for the remainder of the full
term of the new directorship created or the directorship in which the vacancy
occurred and until their successors are duly elected and qualified. No decrease
in the number of directors will shorten the term of any incumbent director.

     Under Ortel's certificate of incorporation, any or all of the directors may
be removed from office only for cause by the affirmative vote of at least
two-thirds of the outstanding shares of Ortel common stock.

AMENDMENTS TO CERTIFICATE OF INCORPORATION

     LUCENT.   Lucent's certificate of incorporation provides that the
affirmative vote of the holders of at least 80% of the voting stock then
outstanding, voting together as a single class, will be required to alter,
amend, adopt any provision inconsistent with or repeal Articles V, VII and VIII
of Lucent's certificate of incorporation, which relate to stockholder action,
the Lucent board of directors and Lucent's by-laws, respectively.

     ORTEL.   Ortel's certificate of incorporation provides that the affirmative
vote of at least two-thirds of the outstanding shares of Ortel common stock will
be required to amend, repeal or adopt any provision inconsistent with Articles
Fifth, Sixth, Seventh, Eighth, Ninth, Tenth, Eleventh, Twelfth, Thirteenth or
Fourteenth, which relate to the Ortel board of directors, stockholder action,
amendment of Ortel's by-laws, indemnification by Ortel and limitation on
personal liability of directors of Ortel.

<PAGE>   66

AMENDMENTS TO BY-LAWS

     LUCENT.   Lucent's certificate of incorporation and by-laws provide that
Lucent's by-laws may be altered or repealed and new by-laws may be adopted:


     - at any annual or special meeting of stockholders, by the affirmative vote
       of holders of a majority of the voting power of the stock issued and
       outstanding and entitled to vote at that meeting, provided that, any
       proposed alteration or repeal of, or the adoption of, any by-law
       inconsistent with Section 2.2, 2.7 or 2.10 of Article II of Lucent's
       by-laws, which relate to special meetings of stockholders, notice of
       stockholder business and nominations and actions by written consent of
       stockholders, respectively, or with Section 3.2, 3.9 or 3.11 of Article
       III of Lucent's by-laws, which relate to the number and tenure of the
       directors, vacancies on the Lucent board of directors and removal of
       directors, respectively, by the stockholders requires the affirmative
       vote of the holders of at least 80% of the voting stock then outstanding,
       voting together as a single class


     - by a majority of the total number of directors Lucent would have if there
       were no vacancies.

     ORTEL.   Ortel's certificate of incorporation authorizes the adoption,
amendment or repeal of any of Ortel's by-laws:

     - by its board of directors with the approval of a majority of the total
       number of authorized directors, whether or not there exist any vacancies
       in previously authorized directorships at the time any resolution
       providing for adoption, amendment or repeal is presented to the board and

     - by the Ortel stockholders with the affirmative vote of the holders of at
       least two-thirds of the outstanding shares of Ortel common stock.

STOCKHOLDER ACTION

     LUCENT.   Lucent's certificate of incorporation provides that any action
required or permitted to be taken by the Lucent stockholders must be effected at
a duly called annual or special meeting and may not be effected by written
consent.

     ORTEL.   Ortel's certificate of incorporation provides that any action
required or permitted to be taken by the Ortel stockholders may be taken only
upon the vote of the Ortel stockholders at an annual or special meeting duly
called and may not be effected by written consent.

NOTICE OF CERTAIN STOCKHOLDER ACTIONS

     LUCENT.   Lucent's certificate of incorporation provides that a stockholder

principal executive offices of Ortel not less than 60 days prior to the
scheduled annual meeting, regardless of any postponements, deferrals or

RIGHTS PLAN


     LUCENT.   Lucent has a rights agreement with The Bank of New York as rights
agent. The following description of the rights agreement is qualified in its
entirety by reference to the terms and conditions of the rights agreement.
Stockholders should read carefully the rights agreement. See "Where You Can Find
More Information" on page 63.


     Under the rights agreement, rights attach to each share of Lucent common
stock outstanding and, when exercisable, entitle the registered holder to
purchase from Lucent one four-hundredth of a share of junior preferred stock,
par value $1.00 per share, at a purchase price of $22.50 per one four-hundredth
of a share, subject to customary anti-dilution adjustments.

     The rights will not be exercisable until the earlier of:

     - 10 days following a public announcement that a person or group has
       acquired beneficial ownership of 10% or more of the outstanding shares of
       Lucent common stock or

     - 10 business days, or that later date as may be determined by the Lucent
       board of directors, following the commencement of, or announcement of an
       intention to make, a tender offer or exchange offer, the consummation of
       which would result in a person or group acquiring beneficial ownership of
       10% or more of the outstanding shares of Lucent common stock.

     The rights will expire on March 31, 2006, unless that date is extended or
unless the rights are earlier redeemed or exchanged by Lucent, in each case as
summarized below.

     In the event that a person or group acquires beneficial ownership of 10% or
more of the outstanding shares of Lucent common stock, each holder of a right,
other than rights beneficially owned by that person or group, which become void,
will have the right to receive upon exercise that number of shares of Lucent
common stock having a market value of two times the purchase price provided for
in the right. In the event that Lucent is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold after a person or group acquires beneficial ownership of 10% or
more of the outstanding shares of Lucent common stock, each holder of a right
will have the right to receive upon exercise that number of shares of common
stock of the acquiring company which at the time of that transaction will have a
market value of two times the purchase price provided for in the right.

     At any time after a person or group acquires beneficial ownership of 10% or
more of the outstanding shares of Lucent common stock and prior to the
acquisition by that person or group of 50% or more of the then outstanding
shares of Lucent common stock, the Lucent board of directors may exchange the
rights, other than rights owned by that person or group which have become void,
in whole or in part, for Lucent common stock or junior preferred stock.

     At any time prior to a person or group acquiring beneficial ownership of
10% or more of the outstanding shares of Lucent common stock, the Lucent board
of directors

                                       60
<PAGE>   70

may redeem the rights in whole, but not in part, at a redemption price of
$0.0025 per right, subject to customary anti-dilution provisions, or may amend
the terms of the rights, in each case, without the consent of the holders of the
rights, at the time, on the basis and upon the conditions that the Lucent board
of directors may establish.

     Junior preferred shares purchasable upon exercise of the rights will not be
redeemable. The junior preferred shares have dividend, voting and liquidation
rights that are intended to result in the value of the one four-hundredth
interest in a junior preferred share purchasable upon exercise of each right
approximating the value of one share of Lucent common stock.

     The rights may have antitakeover effects. The rights will cause substantial
dilution to a person or group of persons that attempts to acquire Lucent on
terms not approved by the Lucent board of directors. The rights should not
interfere with any merger or other business combination approved by the Lucent
board of directors prior to the time that a person or group has acquired such
10% beneficial ownership since the rights may be redeemed or amended by Lucent
until such time.


     ORTEL.   Ortel has a stockholders rights agreement with American Stock
Transfer and Trust Company as rights agent. The following description of the
rights agreement is qualified in its entirety by reference to the terms and
conditions of the rights agreement. Stockholders should read carefully the
rights agreement. See "Where You Can Find More Information" on page 63.


     Under the rights agreement, a right is attached to each share of Ortel
common stock outstanding and, when exercisable, entitles the registered holder
to purchase from Ortel one one-hundredth of a share of junior preferred stock,
par value $1.00 per share, at a purchase price of $140 per one one-hundredth of
a share, subject to customary anti-dilution adjustments.

     The rights will not be exercisable until the earlier of:

     - the tenth day following a public announcement that a person or group has
       acquired beneficial ownership of 15% or more of the outstanding shares of
       Ortel common stock or

     - the tenth day following the commencement of, or announcement of an
       intention to make, a tender or exchange offer by a person or group, the
       consummation of such offer would result in a person or group acquiring
       beneficial ownership of 15% or more of the outstanding shares of Ortel
       common stock.

The rights will expire on March 2, 2005, unless that date is extended or unless
the rights are earlier redeemed or exchanged by Ortel, or are terminated by the
consummation of an acquisition agreement with a third party if such agreement
has been approved by the Ortel board of directors prior to such consummation, in
each case as summarized below.

     In the event that a person or group acquires beneficial ownership of 15% or
more of the outstanding shares of Ortel common stock or merges, or otherwise
combines with, Ortel and the Ortel common stock remains outstanding, each holder
of a right, other than rights beneficially owned by that person or group or its
transferees, which become

                                       61
<PAGE>   71

void, will have the right to receive upon exercise that number of shares of
Ortel common stock equal to the result obtained by multiplying $140 by the
number of one one-hundredths of a share of junior preferred stock for which a
right is exercisable and dividing that product by 50% of the current per share
market price of Ortel common stock.

     At any time prior to the tenth day following a public announcement that a
person or group has acquired beneficial ownership of 15% or more of the
outstanding shares of Ortel common stock, the Ortel board of directors may
redeem the rights in whole, but not in part, at a redemption price of $0.01 per
right, subject to customary anti-dilution provisions.

     Prior to the earlier of the tenth day following a public announcement that
a person or group has acquired beneficial ownership of 15% or more of the
outstanding shares of Ortel common stock or the commencement of, or announcement
of an intention to make, a tender or exchange offer by a person or group, the
consummation of such offer would result in a person or group acquiring
beneficial ownership of 15% or more of the outstanding shares of Ortel common
stock, Ortel may amend the terms of the rights without the consent of the
holders of the rights and otherwise subject to the terms of the stockholders
rights agreement.

     At any time after a person or group acquires beneficial ownership of 15% or
more of the outstanding shares of Ortel common stock and prior to the
acquisition by that person or group of 50% or more of the then outstanding
shares of Ortel common stock, the Ortel board of directors may exchange the
rights, other than rights owned by that person or group which have become void,
in whole or in part, for Ortel common stock.

     The rights are not intended to prevent a takeover of Ortel. They are
designed to deal with the possibility of unilateral actions by hostile acquirers
that could deprive the Ortel board of directors and the Ortel stockholders of
their ability to determine Ortel's destiny and obtain the highest price for the
Ortel common stock. The rights should not interfere with any merger or other
business combination approved by the Ortel board of directors prior to the time
that a person or group has acquired such 15% beneficial ownership since the
rights by its terms terminate in that event.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This proxy statement/prospectus contains certain forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995 with
respect to the financial condition, results of operations, business strategies,
operating efficiencies or synergies, competitive positions, growth opportunities
for existing products, plans and objectives of management, markets for stock of
Lucent and Ortel and other matters. Statements in this proxy
statement/prospectus that are not historical facts are hereby identified as
"forward-looking statements" for the purpose of the safe harbor provided by
Section 21E of the Exchange Act and Section 27A of the Securities Act. These
forward-looking statements, including, without limitation, those relating to the
future business prospects, revenues and income, in each case relating to Lucent
and Ortel, wherever they occur in this proxy statement/prospectus, are
necessarily estimates reflecting the best judgment of the senior management of

be considered in light of various important factors, including those set forth
in this proxy statement/prospectus. Important factors that could cause actual
results to differ materially from estimates or projections contained in the

     - the ability to integrate the operations of Lucent and Ortel, including

     - the effects of vigorous competition in the markets in which Lucent and
       Ortel operate.

     Words such as "estimate," "project," "plan," "intend," "expect," "believe"
and similar expressions are intended to identify forward-looking statements.
These forward-looking statements are found at various places throughout this
proxy statement/prospectus and the other documents incorporated by reference,
including, but not limited to, the Annual Report on Form 10-K for the year ended
September 30, 1999 of Lucent, including any amendments and the Annual Report on
Form 10-K for the year ended April 30, 1999 of Ortel, including any amendments.

statements, which speak only as of the date of this proxy statement/prospectus.

                          AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER dated as of February 7, 2000 ("Agreement"), by
and among LUCENT TECHNOLOGIES INC., a Delaware corporation ("Lucent"), SOLARA
ACQUISITION INC., a Delaware corporation ("Acquisition"), and ORTEL CORPORATION,
a Delaware corporation (the "Company").

                                   BACKGROUND

     A.   The Company is a Delaware corporation with its registered office
located at 32 Loockerman Square, Suite L-100, Dover, Delaware, and has
authorized 25,000,000 shares of common stock, par value $.001 per share
("Company Common Stock"), of which 12,814,280 shares of Company Common Stock are
issued and outstanding, and 5,000,000 shares of preferred stock, par value $.001
per share ("Company Preferred Stock"), of which no shares of Company Preferred
Stock are issued and outstanding. The Company is engaged principally in the
business of designing, manufacturing and supplying advanced optoelectronic
technologies.

     B.   Lucent is a Delaware corporation with its registered office located at
1013 Centre Road, Wilmington, Delaware.

     C.   Acquisition is a wholly-owned subsidiary of Lucent and was formed to
merge with and into the Company so that, as a result of the merger, the Company
will survive and become a wholly-owned subsidiary of Lucent. Acquisition is a
Delaware corporation with its registered office located at 1013 Centre Road,
Wilmington, Delaware, and has authorized an aggregate of 1,000 shares of common
stock, no par value per share ("Acquisition Common Stock").

     D.   The Board of Directors of each of Lucent, Acquisition and the Company
has determined that this Agreement and the merger of Acquisition with and into
the Company (the "Merger") in accordance with the provisions of the Delaware
General Corporation Law (the "DGCL"), and, subject to the terms and conditions
of this Agreement, is advisable and in the best interests of Lucent, Acquisition
and the Company and their respective stockholders.

     E.   The Board of Directors of each of Lucent, Acquisition and the Company
have approved this Agreement, the Merger and the transactions contemplated
hereby.

     F.   The parties intend that, for United States federal income tax
purposes, the Merger shall qualify as a reorganization within the meaning of
Section 368(a) of the Code and that this Agreement shall constitute a plan of
reorganization.

     G.   Immediately following the execution and delivery of this Agreement,
Lucent and the Company will enter into a stock option agreement (the "Option
Agreement"), pursuant to which the Company will grant to Lucent the option to
purchase shares of Company Common Stock, upon the terms and subject to the
conditions set forth therein.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements contained herein and other
good and

                                       A-1
<PAGE>   81

valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto intending to be legally bound do hereby agree
as follows:

     1.   The Merger.

     1.1.   General.   (a) Upon the terms and subject to the conditions of this
Agreement and in accordance with the DGCL, at the Effective Time, (i)
Acquisition shall be merged with and into the Company, (ii) the separate
corporate existence of Acquisition shall cease and (iii) the Company shall be
the surviving corporation (the "Surviving Corporation") and shall continue its
corporate existence under the laws of the State of Delaware.

     (b) The Merger shall become effective at the time of filing of a
certificate of merger substantially in the form of Exhibit A attached hereto
(the "Certificate of Merger"), with the Secretary of State of the State of
Delaware in accordance with the provisions of Section 251 of the DGCL, or at
such later date as the parties may mutually agree (the "Effective Time").
Subject to the terms and conditions of this Agreement, the Company and
Acquisition shall duly execute and file the Certificate of Merger with the
Secretary of State of the State of Delaware at the time of the Closing. The
closing of the Merger (the "Closing") shall take place at the offices of Sidley
& Austin, 875 Third Avenue, New York, New York, at 10:00 a.m., two business days
after the date on which the last of the conditions set forth in Section 6 shall
have been satisfied or waived, or on such other date, time and place as the
parties may mutually agree (the "Closing Date").

     (c) At the Effective Time, the effect of the Merger shall be as provided in
the applicable provisions of the DGCL. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all the property, rights,
privileges, powers and franchises of the Company and Acquisition shall vest in
the Surviving Corporation, and all debts, liabilities, obligations,
restrictions, disabilities and duties of the Company and Acquisition shall
become the debts, liabilities, obligations, restrictions, disabilities and
duties of the Surviving Corporation.

     1.2.   Certificate of Incorporation.   The Certificate of Incorporation of
the Company, as in effect immediately prior to the Effective Time, shall be
amended as set forth in Exhibit B and, as so amended, shall be the Certificate
of Incorporation of the Surviving Corporation until thereafter amended as
provided therein or by applicable law.

     1.3.   By-Laws.   The By-laws of Acquisition, as in effect immediately
prior to the Effective Time, shall be the By-laws of the Surviving Corporation
until thereafter amended as provided therein or by applicable law.

     1.4.   Directors and Officers.   From and after the Effective Time, (a) the
directors of Acquisition at the Effective Time shall be the initial directors of
the Surviving Corporation, each to hold office in accordance with the
Certificate of Incorporation and By-laws of the Surviving Corporation, and (b)
the officers of Acquisition at the Effective Time shall be the initial officers
of the Surviving Corporation, in each case, until their respective successors
are duly elected or appointed and qualified.

                                       A-2
<PAGE>   82

     1.5.   Conversion of Securities.   At the Effective Time, by virtue of the
Merger and without any action on the part of Lucent, Acquisition, the Company or
the holders of any of the following securities:

         (a) each issued and outstanding share of common stock of Acquisition
     shall be converted into one validly issued, fully paid and nonassessable
     share of common stock, no par value per share, of the Surviving
     Corporation;

         (b) each share of Company Common Stock owned or held in treasury by the
     Company and each share of Company Common Stock owned by Acquisition or
     Lucent shall be canceled and retired without any conversion thereof and no
     payment or distribution shall be made with respect thereto; and

         (c) subject to the provisions of Sections 1.6 and 1.7, each share of
     Company Common Stock issued and outstanding immediately prior to the
     Effective Time (other than shares to be canceled in accordance with Section
     1.5(b)) shall be converted into the right to receive 3.1350 (such number as
     adjusted in accordance with Section 1.6, the "Exchange Ratio") of a validly
     issued, fully paid and nonassessable share of Lucent Common Stock. As of
     the Effective Time, each share of Company Common Stock shall no longer be
     outstanding and shall automatically be canceled and retired, and each
     holder of record of a certificate representing any such shares shall cease
     to have any rights with respect thereto, other than the right to receive
     (i) shares of Lucent Common Stock to be issued in consideration therefor
     upon the surrender of such certificate and (ii) any cash, without interest,
     to be paid in lieu of any fractional share of Lucent Common Stock in
     accordance with Section 1.7;

     1.6.   Adjustment of the Exchange Ratio.   In the event that, prior to the
Effective Date, any stock split, combination, reclassification or stock dividend
with respect to the Lucent Common Stock, any change or conversion of Lucent
Common Stock into other securities or any other dividend or distribution with
respect to the Lucent Common Stock (other than regular quarterly dividends)
should occur or, if a record date with respect to any of the foregoing should
occur, appropriate and proportionate adjustments shall be made to the Exchange
Ratio, and thereafter all references to the Exchange Ratio shall be deemed to be
to the Exchange Ratio as so adjusted.

     1.7.   No Fractional Shares.   No certificates or scrip representing
fractional shares of Lucent Common Stock shall be issued upon the surrender for
exchange of Certificates and such fractional share shall not entitle the record
or beneficial owner thereof to vote or to any other rights as a stockholder of
Lucent. In lieu of receiving any such fractional share, the stockholder shall
receive cash (without interest) in an amount rounded to the nearest whole cent,
determined by multiplying (i) the per share closing price on the New York Stock
Exchange, Inc. (the "NYSE") of Lucent Common Stock (as reported on the NYSE
Composite Transactions Tape as such Tape is reported in the Wall Street Journal
or another recognized business publication) on the date immediately preceding
the date on which the Effective Time shall occur (or, if the Lucent Common Stock
did not trade on the NYSE on such prior date, the last day of trading in Lucent
Common Stock on the NYSE prior to the Effective Time) by (ii) the fractional
share to which

                                       A-3
<PAGE>   83

such holder would otherwise be entitled. Lucent shall make available to the
Exchange Agent the cash necessary for this purpose.

     1.8.   Exchange Procedures; Distributions with Respect to Unexchanged
Shares; Stock Transfer Books.   (a) As of the Effective Time, Lucent shall
deposit with the Exchange Agent for the benefit of the holders of shares of
Company Common Stock, certificates representing shares of the Lucent Common
Stock to be issued pursuant to Section 1.5(c) in exchange for the shares of
Company Common Stock. Such shares of Lucent Common Stock, together with any
dividends or distributions with respect thereto pursuant to Sections 1.7 and
1.8(c), are referred to herein as the "Exchange Fund".

     (b) As soon as practicable after the Effective Time, Lucent shall use its
reasonable efforts to cause the Exchange Agent to send to each Person who was,
at the Effective Time, a holder of record of certificates which represented
outstanding Company Common Stock (the "Certificates") which shares were
converted into the right to receive Lucent Common Stock pursuant to Section
1.5(c), a letter of transmittal which (i) shall specify that delivery shall be
effected and risk of loss and title to such Certificates shall pass, only upon
actual delivery thereof to the Exchange Agent and (ii) shall contain
instructions for use in effecting the surrender of the Certificates. Upon
surrender to the Exchange Agent of Certificates for cancellation, together with
such letter of transmittal duly executed and such other documents as the
Exchange Agent may reasonably require, such holder shall be entitled to receive
in exchange therefor (A) a certificate representing the number of whole shares
of Lucent Common Stock into which the Company Common Stock represented by the
surrendered Certificate shall have been converted at the Effective Time, (B)
cash in lieu of any fractional share of Lucent Common Stock in accordance with
Section 1.7 and (C) certain dividends and distributions in accordance with
Section 1.8(c), and the Certificates so surrendered shall then be canceled.
Subject to Section 1.7 and Section 1.8(c), until surrendered as contemplated by
this Section 1.8(b), each Certificate, from and after the Effective Time shall
be deemed to represent only the right to receive, upon such surrender, the
number of shares of Lucent Common Stock into which such Company Common Stock
shall have been converted.

     (c) No dividends or other distributions declared or made after the
Effective Time with respect to the Lucent Common Stock with a record date after
the Effective Time shall be paid to any holder entitled by reason of the Merger
to receive certificates representing Lucent Common Stock and no cash payment in
lieu of a fractional share of Lucent Common Stock shall be paid to any such
holder pursuant to Section 1.7 until such holder shall have surrendered its
Certificates pursuant to this Section 1.8. Subject to applicable law, following
surrender of any such Certificate, such holder shall be paid, in each case,
without interest, (i) the amount of any dividends or other distributions
theretofore paid with respect to the shares of Lucent Common Stock represented
by the certificate received by such holder and having a record date on or after
the Effective Time and a payment date prior to such surrender and (ii) at the
appropriate payment date or as promptly as practicable thereafter, the amount of
any dividends or other distributions payable with respect to such shares of
Lucent Common Stock and having a

                                       A-4
<PAGE>   84

record date on or after the Effective Time but prior to such surrender and a
payment date on or after such surrender.

     (d) If any certificate representing shares of Lucent Common Stock or any
cash is to be issued or paid to any Person other than the registered holder of
the Certificate surrendered in exchange therefor, it shall be a condition to
such exchange that such surrendered Certificate shall be properly endorsed and
otherwise in proper form for transfer and such Person either (i) shall pay to
the Exchange Agent any transfer or other taxes required as a result of the
issuance of such certificates of Lucent Common Stock and the distribution of
such cash payment to such Person or (ii) shall establish to the satisfaction of
the Exchange Agent that such tax has been paid or is not applicable. Lucent or
the Exchange Agent shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to this Agreement to any holder of
shares of Company Common Stock such amounts as Lucent or the Exchange Agent is
required to deduct and withhold with respect to the making of such payment under
the Code, or any provision of state, local or foreign tax law. To the extent
that amounts are so withheld by Lucent or the Exchange Agent, such withheld
amounts shall be treated for all purposes of this Agreement as having been paid
to the holder of the shares of Company Common Stock in respect of which such
deduction and withholding was made by Lucent or the Exchange Agent. All amounts
in respect of taxes received or withheld by Lucent shall be disposed of by
Lucent in accordance with the Code or such state, local or foreign tax law, as
applicable.

     (e) If any Certificate shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the Person claiming such Certificate to
be lost, stolen or destroyed and subject to such other conditions as the Board
of Directors of the Surviving Corporation may impose, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificate the shares of
Lucent Common Stock as determined under Section 1.5(c) and pay any cash,
dividends or other distributions as determined in accordance with Sections 1.7
and 1.8(c) in respect of such Certificate; provided, that Lucent may, in its
reasonable discretion and as a condition precedent to the issuance thereof,
require the owner of such lost, stolen or destroyed Certificate to deliver a
bond in such sum as it may reasonably require as indemnity against any claim
that may be made against Lucent, the Surviving Corporation or the Exchange Agent
with respect to the Certificate alleged to have been lost, stolen or destroyed.

     (f) At the close of business on the day on which the Effective Time occurs,
the stock transfer books of the Company shall be closed and thereafter there
shall be no further registration of transfers of shares of Company Common Stock
on the records of the Company. From and after the Effective Time, the holders of
shares of Company Common Stock outstanding immediately prior to the Effective
Time shall cease to have any rights with respect to such shares except as
otherwise provided herein or by applicable law.

     1.9.   No Further Ownership Rights in Company Common Stock.   All
certificates representing shares of Lucent Common Stock delivered upon the
surrender for exchange of the Certificates in accordance with the terms hereof
(including any cash paid

                                       A-5
<PAGE>   85

pursuant to Section 1.7) shall be deemed to have been delivered (and paid) in
full satisfaction of all rights pertaining to the Company Common Stock
previously represented by such Certificates.

     1.10.   Return of Exchange Fund.   Any portion of the Exchange Fund which
remains undistributed to the former holders of Company Common Stock for six
months after the Effective Time shall be delivered to Lucent, upon its request,
and any such former holders who have not theretofore surrendered to the Exchange
Agent their Certificates in compliance herewith shall thereafter look only to
Lucent for payment of their claim for shares of Lucent Common Stock, any cash in
lieu of fractional shares of Lucent Common Stock and any dividends or
distributions with respect to such shares of Lucent Common Stock. None of
Lucent, Acquisition, the Exchange Agent or the Company shall be liable to any
former holder of Company Common Stock for any such shares of Lucent Common Stock
held in the Exchange Fund (and any cash, dividends and distributions payable in
respect thereof) which are delivered to a public official pursuant to an
official request under any applicable abandoned property, escheat or similar
law.

     1.11.   Further Assurances.   If at any time after the Effective Time the
Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments or assurances or any other acts or things are necessary,
desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in
the Surviving Corporation its right, title or interest in, to or under any of
the rights, privileges, powers, franchises, properties or assets of either the
Company or Acquisition or (b) otherwise to carry out the purposes of this
Agreement, the Surviving Corporation and its proper officers and directors or
their designees shall be authorized to execute and deliver, in the name and on
behalf of either the Company or Acquisition, all such deeds, bills of sale,
assignments and assurances and do, in the name and on behalf of the Company or
Acquisition, all such other acts and things necessary, desirable or proper to
vest, perfect or confirm its right, title or interest in, to or under any of the
rights, privileges, powers, franchises, properties or assets of the Company or
Acquisition, as applicable, and otherwise to carry out the purposes of this
Agreement.

     2.   Representations and Warranties of the Company.   Except as set forth
on the disclosure schedule delivered by the Company to Lucent prior to the
execution of this Agreement (the "Company Disclosure Schedule") and making
reference to the particular subsection of this Agreement to which exception is
being taken, the Company represents and warrants to Lucent and Acquisition as
follows:

     2.1.   Organization.   Each of the Company and its Subsidiaries is a
corporation or other legal entity duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or organization
and has all requisite power and authority and all necessary governmental
approval to carry on its business as it has been and is now being conducted,
except for those jurisdictions where the failure to be so organized, existing or
in good standing individually or in the aggregate could not reasonably be
expected to have a Material Adverse Effect on the Company. Each of the Company
and its Subsidiaries is duly qualified or licensed as a foreign corporation to
do

                                       A-6
<PAGE>   86

business and is in good standing (with respect to jurisdictions which recognize
such concept) in each jurisdiction where the nature of its business or the
ownership, leasing or operation of its properties makes such qualification or
licensing necessary, except where the failure to be so qualified or licensed and
in good standing, would not have a Material Adverse Effect on the Company. The
Company has made available to Lucent prior to the execution of this Agreement
complete and correct copies of its certificate of incorporation and by-laws and
the charter documents for each of its Subsidiaries in each case, as amended to
the date hereof.

     2.2.   Subsidiaries.   Item 2.2 of the Company Disclosure Schedule sets
forth a true and complete list of each of the Company's Subsidiaries. All the
outstanding shares of capital stock of, or other equity interest in, each
Subsidiary of the Company have been validly issued, including in compliance with
all applicable federal and state securities laws, are fully paid and
nonassessable and are owned directly or indirectly by the Company, free and
clear of all Liens and free of any restriction on the right to vote, sell or
otherwise dispose of such capital stock or other ownership interests except
restrictions under applicable law.

     2.3.   Capital Structure.   (a) The authorized capital stock of the Company
consists of 25,000,000 shares of Company Common Stock and 5,000,000 shares of
Company Preferred Stock. At the close of business on February 4, 2000, (i)
12,814,280 shares of Company Common Stock were issued and outstanding; (ii) no
shares of Company Common Stock were held by the Company in its treasury; (iii)
250,000 shares of Company Preferred Stock have been designated as Series A
junior participating preferred stock, par value $.001 per share, and reserved
for issuance upon exercise of the right (the "Company Right") to purchase junior
preferred stock, par value $.001 per share, pursuant to the Rights Agreement
dated as of March 3, 1995 (the "Company Rights Agreement"), between the Company
and First Interstate Bank of California,; (iv) no shares of Company Preferred
Stock were issued and outstanding; (v) not more than 10,026,630 shares of
Company Common Stock were reserved for issuance pursuant to the 1990 Stock
Option Plan, the 1994 Equity Participation Plan, the 1999 Non-Qualified Stock
Option Plan and the Stephen R. Rizzone Non-Qualified Stock Option Agreement
(such plans or agreement, collectively, the "Company Stock Plans"), of which
4,203,226 shares are subject to outstanding Company Stock Options. All
outstanding shares of capital stock of the Company are, and all shares which may
be issued will be, duly authorized, validly issued, fully paid and
nonassessable, not subject to preemptive rights and were issued in compliance in
all material respects with all applicable federal and state securities laws.

     (b) Except as set forth in paragraph (a), at the close of business on
February 4, 2000, no shares of capital stock or other voting securities of the
Company were issued, reserved for issuance or outstanding. There are no
outstanding stock appreciation rights or rights (other than outstanding stock
options or other rights to purchase or receive Company Common Stock granted
under the Company Stock Plans (collectively, "Company Stock Options") or the
Company Rights Agreement) to receive shares of Company Common Stock on a
deferred basis granted under the Company Stock Plans

                                       A-7
<PAGE>   87

or otherwise and no warrants to purchase shares of capital stock of the Company
at any time or upon the occurrence of any stated event. The Company has
delivered to Lucent a complete and correct list, as of February 4, 2000, of the
number of shares of Company Common Stock subject to Company Stock Options and
the exercise prices thereof.

     (c) No bonds, debentures, notes or other indebtedness of the Company having

statements made or incorporated by reference therein based on information
supplied by Lucent specifically for inclusion or incorporation by reference in
the Company Proxy Statement.

connection with this Agreement or the Option Agreement or the transactions
contemplated hereby or thereby, (ii) as disclosed in the Company SEC Documents
filed and publicly available prior to the date of this Agreement (as amended to
the date of this Agreement, the "Company Filed SEC Documents"), (iii) with
respect to the matters set forth in subsection (d) below that do not,

     accordance with GAAP, would be capitalized;

         (h) entry into or commitment to enter into any other material
     transaction except in the ordinary course of business consistent with past
     practice; for the purposes of this subsection (h), a "material transaction"

     SEC Documents or in response to Item 2.10 or 2.11 of the Company Disclosure
     Schedule.

     2.9.   Properties.   (a) Each of the Company and its Subsidiaries has good
and valid title to or a valid leasehold interest in all its properties and

acquired after the date thereof except for (i) properties and assets sold or
otherwise disposed of in the ordinary course of business since the date of such
balance sheet and (ii) properties and assets the loss of which individually or
in the aggregate could reasonably be expected to have a Material Adverse Effect
on the Company.

fulfilled and performed in all material respects its obligations under each of
the leases, contracts and other agreements listed or required to be listed in
Items 2.10 and 2.11 of the Company Disclosure Schedule to the extent such
obligations are required by the terms thereof to have been fulfilled or
performed through the date hereof (except for any such lease, contract or other
agreement which, by its terms, will expire prior to the Effective Time) and
neither the Company nor any such Subsidiary is, and, neither the Company nor any
such Subsidiary is alleged in writing to be, in breach or default under, nor is
there or is there alleged in writing to be any basis for termination of, any

no other party to any such lease, contract or other agreement has breached or
defaulted thereunder. No event has occurred and no condition or state of facts
exists which, with the passage of time or the giving of notice or both, would
constitute such a default or breach by the Company or, to the best knowledge of
the Company, by any such other party. The Company is not currently renegotiating
any such lease, contract or other agreement or paying liquidated damages in lieu
of performance thereunder. Complete and correct copies of each such lease,
contract or other agreement and any amendments thereto have heretofore been
delivered to Lucent.

     2.13.   Litigation.   Item 2.13 of the Disclosure Schedule sets forth (i)
any actions, suits, arbitrations, legal or administrative proceedings or

the

                                      A-13
<PAGE>   93

Disclosure Schedule could reasonably be expected to have a Material Adverse
Effect on the Company.

     2.14.   Compliance with Law.

     (a) Each of the Company and its Subsidiaries has complied with, and is not
in violation of, any law, ordinance or governmental rule or regulation
(collectively, "Laws") to which it or its business is subject, except where the
failure to comply with such Laws could not reasonably be expected to have a
Material Adverse Effect on the Company.

     (b) Each of the Company and its Subsidiaries has obtained all licenses,
permits, certificates or other governmental authorizations (collectively
"Authorizations") necessary for the ownership or use of its assets and
properties or the conduct of its business other than Authorizations (i) which
are ministerial in nature and which the Company or such Subsidiary has no reason
to believe would not be issued in due course and (ii) which, the failure of the
Company or such Subsidiary to possess, could not reasonably be expected to have
a Material Adverse Effect on the Company.

     (c) Neither the Company nor any of its Subsidiaries has received notice of
violation of, or knows of any violation of, any Laws to which it or its business
is subject or any Authorization necessary for the ownership or use of its assets
and properties or the conduct of its business, except for any such violation
which could not reasonably be expected to have a Material Adverse Effect on the
Company.

     2.15.   Intellectual Property; Year 2000.   (a) The Company and its
Subsidiaries own, or are validly licensed or otherwise have the right to use,
all patents, patent rights, trademarks, trade secrets, trade names, service
marks, copyrights and other proprietary intellectual property rights and
computer programs (the "Intellectual Property Rights"), in each case, which are
material to the conduct of the business of the Company and its Subsidiaries.

     (b) To the Company's best knowledge, neither the Company nor any of its
Subsidiaries has infringed upon any patent rights of any other Person, except
(i) as set forth in Item 2.15 of the Company Disclosure Schedule and (ii) for
any such infringement which could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on the Company. In
addition, neither the Company nor any of its Subsidiaries has infringed upon,
misappropriated or otherwise come into conflict with any Intellectual Property
Rights (other than patent rights) or other proprietary information of any other
Person, except for any such infringement which could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on the
Company. Neither the Company nor any of its Subsidiaries has received any
written charge, complaint, claim, demand or notice alleging any such
interference, infringement, misappropriation or violation (including any claim
that the Company or any such Subsidiary must license or refrain from using any
Intellectual Property Rights or other proprietary information of any other
Person) which has not been settled or otherwise fully resolved. To the Company's
best knowledge, no other Person has interfered with, infringed upon,
misappropriated or otherwise come into conflict with any Intellectual Property
Rights or other proprietary information of the

                                      A-14
<PAGE>   94

Company or any of its Subsidiaries, except for any such interference,
infringement, misappropriation or conflict which could not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect on the
Company.

     (c) Assuming that Lucent continues to operate the business of the Company
and its Subsidiaries as presently conducted and proposed to be conducted, then,
to the Company's best knowledge, Lucent's use of the Intellectual Property
Rights or other proprietary information which is material to the conduct of the
business of the Company and its Subsidiaries, taken as a whole, will not
interfere with, infringe upon, misappropriate or otherwise come into conflict
with the Intellectual Property Rights or other proprietary information of any
other Person.

     (d) Each employee, agent, consultant or contractor who has materially
contributed to or participated in the creation or development of any
copyrightable, patentable or trade secret material on behalf of the Company, any
of its Subsidiaries or any predecessor in interest thereto either: (i) is a
party to a "work-for-hire" agreement, or substantially similar agreement, under
which the Company or such Subsidiary is deemed to be the original owner/author
of all property rights therein; or (ii) has executed an assignment or an
agreement to assign in favor of the Company, such Subsidiary or such predecessor
in interest, as applicable all right, title and interest in such material,
except for failures to do so that individually or in the aggregate could not
reasonably be expected to be material to the Company.

     (e) The Company has completed a program directed at ensuring that its and
its Subsidiaries' products (including prior and current products and technology
and products and technology currently under development) are capable upon
installation of (i) operating in the same manner and in accordance with their
specifications on dates in both the Twentieth and Twenty-First centuries and
(ii) accurately processing, providing and receiving date data from, into and
between the Twentieth and Twenty-First centuries, including the years 1999 and
2000, and (iii) recognizing year 2000 as a leap year, provided that all
non-Company products (e.g., hardware, software or firmware) used in or in
combination with the Company's products properly exchange data with the
Company's products in the same manner on dates in both the Twentieth and Twenty-
First centuries. In addition, the Company has installed all available Year
2000-related customer upgrades and has taken all necessary steps to assure that
the year 2000 date change will not adversely affect its operations or the
systems and facilities that support the operations of the Company and its
Subsidiaries, except as could not reasonably be expected to have a Material
Adverse Effect on the Company. Finally, in conjunction with the Year 2000 date
transitions, the Company has not experienced any material date-related failures
of its systems and has no knowledge of any date-related issued experience by its
customers with respect to the Company's products.

     2.16.   Taxes.   (a) Each of the Company and its Subsidiaries has filed all
material tax returns and reports required to be filed by it and all such returns
and reports are complete and correct in all material respects, or requests for
extensions to file such returns or reports have been timely filed, granted and
have not expired, except to the extent that such failures to file, to be
complete or correct or to have extensions granted

                                      A-15
<PAGE>   95

that remain in effect individually or in the aggregate could not reasonably be
expected to have a Material Adverse Effect on the Company. The Company and each
of its Subsidiaries has paid (or the Company has paid on its behalf) all Taxes
shown as due on such returns, and the most recent financial statements contained
in the Company Filed SEC Documents reflect an adequate reserve for all taxes
payable by the Company and its Subsidiaries for all taxable periods and portions
thereof accrued through the date of such financial statements.

     (b) No deficiencies for any taxes have been proposed, asserted or assessed
against the Company or any of its Subsidiaries that are not adequately reserved
for, except for deficiencies that individually or in the aggregate could not
reasonably be expected to have a Material Adverse Effect on the Company. Except
as set forth in Item 2.16 of the Company Disclosure Schedule, the federal income
tax returns of the Company and each of its Subsidiaries consolidated in such
returns have closed by virtue of the applicable statute of limitations.

     (c) Neither the Company nor any of its Subsidiaries has taken any action or
knows of any fact, agreement, plan or other circumstance that could reasonably
be expected to prevent the Merger from qualifying as a reorganization within the
meaning of Section 368(a) of the Code.

     (d) Except as set forth in Item 2.16 of the Company Disclosure Schedule,
the Company Benefit Plans and other Company employee compensation arrangements
in effect as of the date of this Agreement have been designed so that the
disallowance of a material deduction under Section 162(m) of the Code for
employee remuneration will not apply to any amounts paid or payable by the
Company or any of its Subsidiaries under any such plan or arrangement and, to
the best knowledge of the Company, no fact or circumstance exists that could
reasonably be expected to cause such disallowance to apply to any such amounts.

     (e) Neither the Company nor any of its Subsidiaries has constituted either
a "distributing corporation" or a "controlled corporation" in a distribution of
stock qualifying for tax-free treatment under Section 355 of the Code (x) in the
two years prior to the date of this Agreement or (y) in a distribution which
could otherwise constitute part of a "plan" or "series of related transactions"
(within the meaning of Section 355(e) of the Code) in conjunction with the
Merger.

     (f) Neither the Company nor any of its Subsidiaries is a party (other than
as an investor) to any industrial development bond.

     2.17.   Absence of Changes in Benefit Plans.   Except as set forth in Item
2.17 of the Company Disclosure Schedule, since the date of the most recent
audited financial statements included in the Company Filed SEC Documents, there
has not been any adoption or amendment by the Company or any of its subsidiaries
of any collective bargaining agreement or any bonus, pension, profit sharing,
deferred compensation, incentive compensation, stock ownership, stock purchase,
stock option, phantom stock, retirement, vacation, severance, disability, death
benefit, hospitalization, medical, welfare benefit or other plan, arrangement or
understanding providing benefits to any current or

                                      A-16
<PAGE>   96

former employee, officer or director of the Company or any of its Subsidiaries
(collectively, the "Company Benefit Plans"), or any change in any actuarial or
other assumption used to calculate funding obligations with respect to any the
Company pension plans, or any change in the manner in which contributions to any
the Company pension plans are made or the basis on which such contributions are
determined.

     2.18.   ERISA Compliance.   (a) With respect to the Company Benefit Plans,
no event has occurred and, to the best knowledge of the Company, there exists no
condition or set of circumstances, in connection with which the Company or any
of its Subsidiaries could be subject to any liability that individually or in
the aggregate could reasonably be expected to have a Material Adverse Effect on
the Company under the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), the Code or any other applicable law.

     (b) Each Benefit Plan has been administered in accordance with its terms,
except for any failures so to administer any Benefit Plan that individually or
in the aggregate could not reasonably be expected to have a Material Adverse
Effect on the Company. The Company, its Subsidiaries and all the Company Benefit
Plans are in compliance with the applicable provisions of ERISA, the Code and
all other applicable laws and the terms of all applicable collective bargaining
agreements, except for any failures to be in such compliance that individually
or in the aggregate could not reasonably be expected to have a Material Adverse
Effect. Except as set forth in Item 2.18(b) of the Company Disclosure Schedule,
each Benefit Plan that is intended to be qualified under Section 401(a) or
401(k) of the Code has received a favorable determination letter from the
Internal Revenue Service (the "IRS") that it is so qualified and each trust
established in connection with any Company Benefit Plan that is intended to be
exempt from federal income taxation under Section 501(a) of the Code has
received a determination letter from the IRS that such trust is so exempt. To
the best knowledge of the Company, no fact or event has occurred since that date
of any determination letter from the IRS which could reasonably be expected to
affect adversely the qualified status of any such Benefit Plan or the exempt
status of any such trust. There are no pending or, to the best knowledge of the
Company, threatened lawsuits, claims, grievances, investigations or audits of
any Benefit Plan that, individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect.

     (c) Neither the Company nor any of its Subsidiaries has incurred any
liability under Title IV of ERISA (other than liability for premiums to the
Pension Benefit Guaranty Corporation arising in the ordinary course). No Benefit
Plan has incurred an "accumulated funding deficiency" (within the meaning of
Section 302 of ERISA or Section 412 of the Code) whether or not waived. To the
best knowledge of the Company, there are no facts or circumstances that could
reasonably be expected to materially change the funded status of any Benefit
Plan that is a "defined benefit" plan (as defined in Section 3(35) of ERISA)
since the date of the most recent actuarial report for such plan. No Benefit
Plan is a "multi employer plan" within the meaning of Section 3(37) of ERISA.

     (d) Except as set forth in Item 2.18(d) of the Company Disclosure Schedule,
no employee of the Company will be entitled to any additional benefits or any
acceleration of the time of payment or vesting of any benefits under any Benefit
Plan as a result of the transactions contemplated by this Agreement or the
Option Agreement. Except as set forth in Item 2.18(d) of the Company Disclosure
Schedule, no amount payable, or economic benefit provided, by the Company or its
Subsidiaries (including any acceleration of the time of payment or vesting of
any benefit) could be considered an "excess parachute payment" under Section
280G of the Code as a result of the transactions contemplated by this Agreement
or the Option Agreement. Except as set forth in Item 2.18(d) of the Company
Disclosure Schedule, no Person is entitled to receive any additional payment
from the Company or its Subsidiaries or any other Person (a "Parachute Gross-Up
Payment") in the event that the excise tax of Section 4999 of the Code is
imposed on such Person. Except as set forth in Item 2.18(d) of the Company
Disclosure Schedule, the Board of Directors of the Company or any of its
Subsidiaries has not granted to any Person any right to receive any Parachute
Gross-Up Payment.

     (e) Except as set forth in Item 2.18(e) of the Company Disclosure Schedule,
neither the Company nor any of its Subsidiaries has any liability or obligation
under any "employee welfare benefit plans" (as defined in Section 3(1) of ERISA)
to provide life insurance or medical benefits after termination of employment to
any employee or dependent other than as required by Part 6 of Title I of ERISA.

     (f) The Company and its Subsidiaries are in compliance with all federal,
state and local requirements regarding employment, except for any failures to
comply that individually or in the aggregate could not reasonably be expected to
have a Material Adverse Effect on the Company. Neither the Company nor any of
its Subsidiaries is a party to any collective bargaining or other labor union
contract applicable to persons employed by the Company or any of its
Subsidiaries and no collective bargaining agreement is being negotiated by the
Company or any of its Subsidiaries. As of the date of this Agreement, there is
no labor dispute, strike or work stoppage against the Company or any of its
Subsidiaries pending or, to the knowledge of the Company, threatened which may
interfere with the respective business activities of the Company or any of its
Subsidiaries, except where such dispute, strike or work stoppage individually or
in the aggregate could not reasonably be expected to have a Material Adverse
Effect on the Company. As of the date of this Agreement, to the knowledge of the
Company, none of the Company, any of its Subsidiaries or any of their respective
representatives or employees has committed any unfair labor practice in
connection with the operation of the respective business of the Company or any
of its Subsidiaries, and there is no charge or complaint against the Company or
any of its Subsidiaries by the National Labor Relations Board or any comparable
governmental agency pending or threatened in writing, in each case except where
such actions, charges or complaints, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect on the Company.

     2.19.   Environmental Laws.   The Company has not received any notice or
claim (and is not aware of any facts that would form a reasonable basis for any
claim), or entered into any negotiations or agreements with any other Person,
and, to the best knowledge of the Company, neither the Company nor any of its
Subsidiaries is the subject of any investigation by any governmental or
regulatory authority, domestic or foreign, relating to any material or
potentially material liability or remedial action under any Environmental Laws.
There are no pending or, to the best knowledge of the Company, threatened,
actions, suits or proceedings against the Company, any of its Subsidiaries or
any of their respective properties, assets or operations asserting any such
liability or seeking any remedial action in connection with any Environmental
Laws, which, in either case, could not reasonably be expected to have a Material
Adverse Effect on the Company.

     2.20.   Voting Requirements; Board Approval and Recommendation.   (a) The
affirmative vote of the holders of a majority of all outstanding shares of
Company Common Stock at the Company Stockholders Meeting to adopt this Agreement
(the "Company Stockholder Approval") is the only vote of the holders of any
class or series of the Company's capital stock necessary to approve and adopt
this Agreement, the Option Agreement and the transactions contemplated hereby
and thereby.

     (b) The Board of Directors of the Company, by resolutions duly adopted by
unanimous vote of those voting at a meeting duly called and held and not

has declared the Merger to be advisable, (ii) approved this Agreement, the
Option Agreement, the Merger and the other transactions contemplated hereby and
thereby, (iii) resolved (subject to Section 5.2) to recommend this Agreement and

Registration Statement and the Company Proxy Statement of the recommendation of
such Board of Directors.

     2.21.   State Takeover Statutes.   The Board of Directors of the Company
(including the disinterested directors thereof) has approved the terms of this
Agreement and the Option Agreement and the consummation of the Merger and the
other transactions contemplated by this Agreement and Option Agreement, and such
approval constitutes approval of the Merger and the other transactions
contemplated by this Agreement and the Option Agreement by the Company's Board
of Directors under the provisions of Section 203 of the DGCL and represents all
the action necessary to ensure that such Section 203 does not apply to Lucent in
connection with the Merger and the other transactions contemplated by this
Agreement and the Option Agreement. To the knowledge of the Company, no other
state takeover statute is applicable to the Merger or the other transactions
contemplated hereby and by the Option Agreement.

     2.22.   Company Rights Agreement.   The Company has taken all necessary
action (i) to render the Company Rights inapplicable to the Merger and the other
transactions

                                      A-19
<PAGE>   99

contemplated by this Agreement or the Option Agreement and (ii) to ensure that
(x) neither Lucent nor any of its affiliates is an Acquiring Person (as defined
in the Company Rights Agreement) and (y) a Distribution Date (as defined in the
Company Rights Agreement) does not occur by reason of the announcement or
consummation of the Merger or the consummation of any of the other transactions
contemplated by this Agreement or the Option Agreement.

     2.23.   Brokers.   No broker, investment banker, financial advisor or other
Person, other than SoundView Technology Group, Inc., or its successor, the fees
and expenses of which will be paid by the Company, is entitled to any broker's,
finder's, financial advisor's or other similar fee or commission in connection
with the transactions contemplated by this Agreement and the Option Agreement
based upon arrangements made by or on behalf of the Company. The Company has
furnished to Lucent true and complete copies of all agreements under which any
such fees or expenses are payable and all indemnification and other agreements
related to the engagement of the Persons to whom such fees are payable.

     2.24.   Opinion of Financial Advisor.   The Company has received the
opinion of SoundView Technology Group, Inc., or its successor, dated the date of
this Agreement, to the effect that, as of such date, the Exchange Ratio is fair
from a financial point of view to holders of shares of the Company Common Stock
(other than Lucent and its affiliates), a signed copy of which opinion has been
or will promptly be delivered to Lucent.

     2.25.   Disclosure.   None of the representations or warranties of the
Company contained herein, none of the information contained in the Company
Disclosure Schedule, and none of the other information or documents furnished or
to be furnished to Lucent or Acquisition by the Company or any of its
Subsidiaries or pursuant to the terms of this Agreement, when taken as a whole,
contains, or at the Effective Time will contain, any untrue statement of a
material fact or omits, or at the Effective Time will omit, to state a material
fact required to be stated herein or therein necessary to make the statements
herein or therein, in light of the circumstances under which they were made, not
misleading in any material respect.

     3.   Representations and Warranties of Lucent and Acquisition.   Except as
set forth on the disclosure schedule delivered by Lucent to the Company prior to
the execution of this Agreement (the "Lucent Disclosure Schedule") and making
reference to the particular subsection of this Agreement to which exception is
being taken, Lucent and Acquisition represent and warrant to the Company as
follows:

     3.1.   Organization, Standing and Corporate Power.   Each of Lucent and
Acquisition is a corporation or other legal entity duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
organized and has the requisite corporate or other power, as the case may be,
and authority to carry on its business as now being conducted, except for those
jurisdictions where the failure to be so organized, existing or in good standing
individually or in the aggregate could not reasonably be expected to have a
Material Adverse Effect. Each of Lucent and Acquisition is duly qualified or
licensed to do business and is in good standing (with respect to jurisdictions

                                      A-20
<PAGE>   100

which recognize such concept) in each jurisdiction in which the nature of its
business or the ownership, leasing or operation of its properties makes such
qualification or licensing necessary, except for those jurisdictions where the
failure to be so qualified or licensed or to be in good standing individually or
in the aggregate could not reasonably be expected to have a Material Adverse
Effect.

     3.2.   Capital Structure.   Except as set forth in Item 3.3 of the Lucent
Disclosure Schedule, the authorized capital stock of Lucent consists of (i)
6,000,000,000 shares of common stock, par value $.01 per share ("Lucent Common
Stock") and (ii) 250,000,000 shares of preferred stock, par value $1.00 per
share ("Lucent Authorized Preferred Stock"), of which 7,500,000 shares have been

Preferred Stock"). As of December 31, 1999, (i) approximately 3,178,657,861
shares of Lucent Common Stock were issued and outstanding, (ii) no shares of
Lucent Junior Stock Preferred Stock were issued and outstanding and (iii) other
than the Lucent Junior Preferred Stock, no other shares of Lucent Authorized
Preferred Stock are issued and outstanding. As of the date of this Agreement, no
bonds, debentures, notes or other indebtedness of Lucent having the right to
vote (or convertible into, or exchangeable for, securities having the right to
vote) on any matters on which stockholders of Lucent may vote are issued or
outstanding. All outstanding shares of capital stock of Lucent are, and all
shares which may be issued will be, when issued, duly authorized, validly
issued, fully paid and nonassessable and not subject to preemptive rights.

     3.3.   Authority.   Each of Lucent and Acquisition has all requisite
corporate power and authority to enter into this Agreement and to consummate the

Agreement by Lucent, and the consummation by Lucent and Acquisition of the
transactions contemplated by this Agreement and the consummation by Lucent of
the transactions contemplated by the Option Agreement have been duly authorized
by all necessary corporate action on the part of Lucent and Acquisition, as

Acquisition and, constitutes the legal, valid and binding obligation of Lucent
and Acquisition, enforceable against each of them in accordance with its terms.
The Option Agreement has been duly executed and delivered by Lucent, and,
constitutes a legal, valid and binding obligation of Lucent, enforceable against
Lucent in accordance with its terms.

     3.4.   No Conflict.   (a) The execution and delivery of this Agreement and
the Option Agreement do not, and the consummation of the transactions
contemplated by this Agreement and the Option Agreement and compliance with the
provisions of this Agreement and the Option Agreement will not, conflict with,
or result in any violation of, or default (with or without notice or lapse of
time, or both) under, or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of a benefit under, or result in the
creation of any Lien upon any of the properties or assets of

                                      A-21
<PAGE>   101

case of clauses (ii) and (iii), any such conflicts, violations, defaults,
rights, losses or Liens that individually or in the aggregate could not
reasonably be expected to have a Material Adverse Effect.

     (b) No consent, approval, order or authorization of, action by, or in
respect of, or registration, declaration or filing with, any Governmental Entity

execution and delivery of this Agreement by Lucent and Acquisition or the

investigations pending or, to the best knowledge of Lucent, threatened against

Lucent SEC Documents complied in all material respects with the requirements of
the Securities Act or the Exchange Act, as the case may be, and the rules and
regulations of the SEC promulgated thereunder applicable to such Lucent SEC
Documents. Except to the extent that information contained in any Lucent SEC
Document has been revised or superseded by a later filed Lucent SEC Document,
none of the Lucent SEC Documents when filed contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. The financial

applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto, have been prepared in accordance with generally

and its consolidated Subsidiaries as of the dates thereof and the consolidated
results of their operations and cash flows for the periods then ended (subject,

adjustments). Except for liabilities (i) reflected in such financial statements
or in the notes thereto, (ii) incurred in the ordinary course of business
consistent with past practice since the date of the most recent audited
financial statements included in the Lucent Filed SEC Documents, (iii) incurred
in connection with this Agreement or the Option Agreement or the transactions
contemplated hereby or thereby, or (iv) disclosed in Item 3.6 of the Lucent
Disclosure Schedule, neither Lucent nor any of its Subsidiaries has any
liabilities or obligations of any nature which, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

     3.7.   Information Supplied.   None of the information supplied or to be
supplied by Lucent specifically for inclusion or incorporation by reference in
(i) the Lucent Registration Statement will, at the time the Lucent Registration
Statement becomes effective under the Securities Act, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading or
(ii) the Company Proxy Statement will, at the date it is first mailed to the
Company's stockholders or at the time of the Company Stockholders Meeting,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading. The Lucent Registration Statement will comply as to form in all
material respects with the requirements of the Exchange Act and the rules and
regulations thereunder, except that no representation or warranty is made by
Lucent with respect to

                                      A-23
<PAGE>   103

statements made or incorporated by reference therein based on information
supplied by the Company specifically for inclusion or incorporation by reference
in the Lucent Registration Statement.

     3.8.   Absence of Certain Changes.   Except for liabilities incurred in
connection with this Agreement or the Option Agreement or the transactions
contemplated hereby or thereby and except as disclosed in the Lucent SEC
Documents filed and publicly available prior to the date of this Agreement (the
"Lucent Filed SEC Documents"), since September 30, 1999, Lucent and its
Subsidiaries have conducted their business only in the ordinary course, and
there has not been (i) any event or occurrence which could have a Material
Adverse Effect, (ii) except insofar as may have been or required by a change in
GAAP, any change in accounting methods, principles or practices by Lucent
materially affecting its assets, liabilities or business, (iii) any tax election
that individually or in the aggregate could reasonably be expected to have a
Material Adverse Effect or any of its tax attributes or any settlement or
compromise of any material income tax liability, or (iv) any split, combination
or reclassification of any of Lucent's capital stock or any issuance or the
authorization of any issuance of any other securities in respect of, in lieu of
or in substitution, for shares of Lucent's capital stock, except for issuances
of Lucent Common Stock upon the exercise of outstanding stock options or other
rights to purchase or receive Lucent Common Stock granted under stock
compensation plans maintained by Lucent, various plans of companies acquired by
Lucent, and warrants issued by companies acquired by Lucent, in each case
awarded prior to the date hereof in accordance with their present terms.

     3.9.   Brokers.   No broker, investment banker, financial advisor or other
Person is entitled to any broker's, finder's, financial advisor's or other
similar fee or commission in connection with the transactions contemplated by
this Agreement and the Option Agreement based upon arrangements made by or on
behalf of Lucent.

     3.10.   Interim Operations of Acquisition.   Acquisition was formed solely
for the purpose of engaging in transactions of the type contemplated hereby, has
engaged in no other business activities and has conducted its operations only as
contemplated hereby.

     3.11.   Taxes.   Neither Lucent nor any of its Subsidiaries has taken any
action or knows of any fact, agreement, plan or other circumstance that could

     change any actuarial or other assumption used to calculate funding
     obligations with respect to any pension plan, or change the manner in which

         (q) except for normal increases in the ordinary course of business
     consistent with past practice that, in the aggregate, do not materially
     increase benefits or compensation expenses of the Company or its
     Subsidiaries, or as contemplated hereby or by the terms of any employment
     agreement in existence on the date hereof, increase the cash compensation
     of any director, executive officer or other key employee or pay any benefit
     or amount not required by a plan or arrangement as in effect on the date of
     this Agreement to any such Person; provided that nothing contained herein
     shall prohibit the Company from paying 1999 bonuses that have been earned
     under its incentive bonus plans in accordance with the terms of such plans
     as in effect on the date hereof consistent with past practice; or

         (r) announce an intention, commit or agree to do any of the foregoing.

     5. Additional Agreements.

     5.1. Access; Documents; Supplemental Information.   (a) From and after the
date hereof until the Closing, the Company shall afford, shall cause its

accountants, counsel and other representatives of Acquisition and Lucent, upon
reasonable notice, reasonable access during normal business hours to the
properties, books and records including tax returns filed and those in the
process of being prepared by the Company or any of its Subsidiaries and the
right to consult with the officers, employees, accountants, counsel and other

Subsidiaries as Acquisition and Lucent shall from time to time reasonably
require.

     (b) From the date of this Agreement through and including the Closing,
Acquisition, Lucent and the Company agree to furnish to each other copies of any
notices, documents, requests, court papers, or other materials received from any
governmental agency or any other third party with respect to the transactions
contemplated by this Agreement, except where it is obvious from such notice,
document, request, court paper or other material that the other party was
already furnished with a copy thereof.

     (c) Except as required by law, the Company and Lucent shall not, and shall
not permit any of their respective Subsidiaries to, voluntarily take any action
that would, or that could reasonably be expected to, result in (i) any of the
representations and warranties of such party set forth in this Agreement or the
Option Agreement that are qualified as to materiality becoming untrue at the
Effective Time, (ii) any of such

                                      A-27
<PAGE>   107

representations and warranties that are not so qualified becoming untrue in any
material respect at the Effective Time, or (iii) any of the conditions to the
Merger set forth in Section 6 not being satisfied.

     (d) The Company shall give prompt notice to Lucent, and Lucent shall give
prompt notice to the Company, of (i) the occurrence, or non-occurrence, of any
event which would be likely to cause (A) any representation or warranty
contained in this Agreement or the Option Agreement to be untrue or inaccurate
in any material respect or (B) any covenant, condition or agreement contained in
this Agreement or the Option Agreement not to be complied with or satisfied; and
(ii) any failure of the Company, Lucent or Acquisition, 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 that the delivery of any notice pursuant
to this Section 5.1(d) shall not limit or otherwise affect the remedies
available to the party receiving such notice.

days after the date of such filing with the SEC.

     (f) Lucent shall deliver to the Company, without charge, a copy of any
filing made by Lucent with the SEC under the Exchange Act, including, without

the date of such filing with the SEC.

     5.2. No Solicitation by the Company.   (a) the Company shall not, nor shall
it permit any of its Subsidiaries to, nor shall it authorize or permit any of
its directors, officers or employees or any investment banker, financial
advisor, attorney, accountant or other representative retained by it or any of
its Subsidiaries to, directly or indirectly through another person, (i) solicit,
initiate or encourage (including by way of furnishing information), or take any
other action to facilitate, any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Takeover Proposal (as
defined below) or (ii) participate in any discussions or negotiations regarding
any Takeover Proposal; provided, however, that if, at any time prior to the date
of the Company Stockholders Meeting (the "Applicable Period"), the Board of
Directors of the Company determines in good faith, after consultation with
outside counsel, that it is necessary to do so in order to comply with its
fiduciary duties to the Company's stockholders under applicable law, the Company
and its representatives may, in response to a Superior Proposal which was not
solicited by it or which did not otherwise result from a breach of this Section
5.2(a), and subject to providing prior written notice of its decision to take
such action to Lucent and compliance with Section 5.2(c), (x) furnish
information with respect to the Company and its Subsidiaries to any person
making a Superior Proposal pursuant to a customary confidentiality agreement (as
determined by the Company after consultation with its outside counsel) and (y)
participate in discussions or negotiations regarding such Superior Proposal. For
purposes of this Agreement, "Takeover Proposal" means any inquiry, proposal or
offer from any person relating to any direct or indirect acquisition or purchase
of 15% or more

                                      A-28
<PAGE>   108

of the assets of the Company and its Subsidiaries, taken as a whole, or 15% or
more of any class or series of equity securities of the Company or any of its
Subsidiaries, any tender offer or exchange offer that if consummated would
result in any person beneficially owning 15% or more of any class or series of
equity securities of the Company or any of its Subsidiaries, or any merger,
consolidation, business combination, recapitalization, liquidation, dissolution
or similar transaction involving the Company or any of its Subsidiaries, other
than the transactions contemplated by this Agreement.

     (b) Neither the Board of Directors of the Company nor any committee thereof
shall (i) withdraw or modify, or propose publicly to withdraw or modify, in a
manner adverse to Lucent, the approval or recommendation by such Board of
Directors or such committee of the Merger or this Agreement, (ii) approve or
recommend, or propose publicly to approve or recommend, any Takeover Proposal,
or (iii) approve or recommend, or propose to approve or recommend, or execute or
enter into, any letter of intent, agreement in principle, merger agreement,
acquisition agreement, option agreement or other similar agreement or propose
publicly or agree to do any of the foregoing (each, an "Acquisition Agreement")
related to any Takeover Proposal, other than any such agreement entered into
concurrently with a termination pursuant to the next sentence in order to
facilitate such action. Notwithstanding the foregoing, during the Applicable
Period, in response to a Superior Proposal which was not solicited by the
Company and which did not otherwise result from a breach of Section 5.2(a), if
the Board of Directors of the Company determines in good faith, after
consultation with outside counsel, that it is necessary to do so in order to
comply with its fiduciary duties to the Company's stockholders under applicable
law, the Board of Directors of the Company may (subject to this and the
following sentence) terminate this Agreement (and concurrently with or after
such termination, if it so chooses, cause the Company to enter into any
Acquisition Agreement with respect to any Superior Proposal), but only at a time
that is during the Applicable Period and is after the tenth business day
following Lucent's receipt of written notice advising Lucent that the Board of
Directors of the Company is prepared to accept a Superior Proposal, specifying
the material terms and conditions of such Superior Proposal and identifying the
person making such Superior Proposal. For purposes of this Agreement, a
"Superior Proposal" means any proposal made by a third party to acquire,
directly or indirectly, including pursuant to a tender offer, exchange offer,
merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction, for consideration consisting of cash and/or
securities, more than 50% of the combined voting power of the shares of the
Company Common Stock then outstanding or all or substantially all the assets of
the Company and otherwise on terms which the Board of Directors of the Company
determines in its good faith judgment (based on the advice of a financial
advisor of nationally recognized reputation) to be more favorable to the
Company's stockholders than the Merger and for which financing, to the extent
required, is then committed or which, in the good faith judgment of the Board of
Directors of the Company, is reasonably capable of being obtained by such third
party.

     (c) In addition to the obligations of the Company set forth in paragraphs
(a) and (b) of this Section 5.2, the Company shall promptly (and no later than
48 hours) advise

                                      A-29
<PAGE>   109

Lucent orally and in writing of any request for information or of any Takeover
Proposal, the material terms and conditions of such request or Takeover Proposal
and the identity of the Person making such request or Takeover Proposal. The
Company will keep Lucent informed of the status and material terms and
conditions (including amendments or proposed amendments) of any such request or
Takeover Proposal.

     (d) Nothing contained in this Section 5.2 shall prohibit the Company from
taking and disclosing to its stockholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act or from making any disclosure to the
Company's stockholders if, in the good faith judgment of the Board of Directors
of the Company, after consultation with outside counsel, failure so to disclose
would be inconsistent with its obligations under applicable law; provided, that,
except as expressly permitted by this Section 5.2, neither the Company nor its
Board of Directors nor any committee thereof shall withdraw or modify, or
propose publicly to withdraw or modify, its position with respect to this
Agreement or the Merger or approve or recommend, or propose publicly to approve
or recommend, a Takeover Proposal.

     5.3. Preparation of the Lucent Registration Statement and Company Proxy
Statement; Company Stockholders Meeting.   (a) As soon as practicable following
the date of this Agreement, the Company shall prepare and file with the SEC the
Company Proxy Statement and Lucent shall prepare and file with the SEC the
Lucent Registration Statement, in which the Company Proxy Statement will be
included as a prospectus. Each of the Company and Lucent shall use its
reasonable best efforts to have the Lucent Registration Statement declared
effective under the Securities Act as promptly as practicable after such filing.
The Company will use its reasonable best efforts to cause the Company Proxy
Statement to be mailed to the Company's stockholders as promptly as practicable
after the Lucent Registration Statement is declared effective under the
Securities Act. Lucent shall also take any action (other than qualifying to do
business in any jurisdiction in which it is not now so qualified or to file a
general consent to service of process) required to be taken under any applicable
state securities laws in connection with the issuance of Lucent Common Stock in
the Merger and the Company shall furnish all information concerning the Company
and the holders of Company Common Stock as may be reasonably requested in
connection with any such action. No filing of, or amendment or supplement to,
the Lucent Registration Statement will be made by Lucent, or the Company Proxy
Statement will be made by the Company, without providing the other party the
opportunity to review and comment thereon. Lucent will advise the Company,
promptly after it receives notice thereof, of the time when the Lucent
Registration Statement has become effective or any supplement or amendment has
been filed, the issuance of any stop order, the suspension of the qualification
of the Lucent Common Stock issuable in connection with the Merger for offering
or sale in any jurisdiction, or any request by the SEC for amendment of the
Lucent Registration Statement or comments thereon and responses thereto or
requests by the SEC for additional information. The Company will inform Lucent,
promptly after it receives notice thereof, of any request by the SEC for the
amendment of the Company Proxy Statement or comments thereon and responses
thereto or requests by the SEC for additional information. If at any time prior
to the Effective Time any

                                      A-30
<PAGE>   110

information relating to the Company or Lucent, or any of their respective
affiliates, officers or directors, should be discovered by the Company or Lucent
which should be set forth in an amendment or supplement to any of the Lucent
Registration Statement or the Company Proxy Statement, so that any of such
documents would not include any misstatement of a material fact or omit to state
any material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, the party that
discovers such information shall promptly notify the other parties hereto and an
appropriate amendment or supplement describing such information shall be
promptly filed with the SEC and, to the extent required by law, disseminated to
the stockholders of the Company.

     (b) The Company shall, as soon as practicable following the date of this
Agreement, establish a record date (which will be as soon as practicable
following the date of this Agreement) for, duly call, give notice of, convene
and hold a meeting of its stockholders (the "Company Stockholders Meeting")
solely for the purpose of obtaining the Company Stockholder Approval. The
Company shall, through its Board of Directors, recommend to its stockholders the
approval and adoption of this Agreement, the Merger and the other transactions
contemplated hereby. Without limiting the generality of the foregoing but
subject to its right to terminate this Agreement pursuant to Section 5.2(b), the
Company agrees that its obligations pursuant to the first sentence of this
Section 5.3(b) shall not be affected by the commencement, public proposal,
public disclosure or communication to the Company of any Takeover Proposal.

     5.4. Letter of the Company's Accountants; Letter of Lucent's
Accountants.   (a) The Company shall use its reasonable best efforts to cause
its independent public accountants to deliver to Lucent two letters from the
Company's independent public accountants, one dated a date within two business
days before the date on which the Lucent Registration Statement shall become
effective and one dated a date within two business days before the Closing Date,
each addressed to Lucent, in form and substance reasonably satisfactory to
Lucent and customary in scope and substance for comfort letters delivered by
independent public accountants in connection with registration statements
similar to the Lucent Registration Statement.

     (b) Lucent shall use its reasonable best efforts to cause its independent
public accountants to deliver to the Company two letters from Lucent's
independent public accountants, one dated a date within two business days before
the date on which the Lucent Registration Statement shall become effective and
one dated a date within two business days before the Closing Date, each
addressed to the Company, in form and substance reasonably satisfactory to the
Company and customary in scope and substance for comfort letters delivered by
independent public accountants in connection with registration statements
similar to the Lucent Registration Statement.

     5.5. Reasonable Best Efforts.   (a) Upon the terms and subject to the
conditions set forth in this Agreement, each of the parties agrees to use its
reasonable best efforts to take, or cause to be taken, all actions, and to do,
or cause to be done, and to assist and cooperate with the other parties in
doing, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Merger

                                      A-31
<PAGE>   111

and the other transactions contemplated by this Agreement and the Option
Agreement, including (i) the obtaining of all necessary actions or nonactions,
waivers, consents and approvals from Governmental Entities and the making of all
necessary registrations and filings and the taking of all steps as may be
necessary to obtain an approval or waiver from, or to avoid an action or
proceeding by, any Governmental Entity, (ii) the obtaining of all necessary
consents, approvals or waivers from third parties, (iii) the defending of any
lawsuits or other legal proceedings, whether judicial or administrative,
challenging this Agreement or the Option Agreement or the consummation of the
transactions contemplated by this Agreement or the Option Agreement, including
seeking to have any stay or temporary restraining order entered by any court or
other Governmental Entity vacated or reversed, and (iv) the execution and
delivery of any additional instruments necessary to consummate the transactions
contemplated by, and to fully carry out the purposes of, this Agreement and the
Option Agreement.

     (b) In connection with and without limiting the foregoing, the Company and
Lucent shall (i) take all action reasonably necessary to ensure that no state
takeover statute or similar statute or regulation is or becomes applicable to
the Merger, this Agreement, the Option Agreement or any of the other
transactions contemplated by this Agreement or the Option Agreement and (ii) if
any state takeover statute or similar statute or regulation becomes applicable
to the Merger, this Agreement, the Option Agreement or any other transaction
contemplated by this Agreement or the Option Agreement, take all action
reasonably necessary to ensure that the Merger and the other transactions
contemplated by this Agreement and the Option Agreement may be consummated as
promptly as practicable on the terms contemplated by this Agreement and the
Option Agreement and otherwise to minimize the effect of such statute or
regulation on the Merger and the other transactions contemplated by this
Agreement and the Option Agreement.

     5.6. Stock Options.   (a) As soon as practicable following the date of this
Agreement, the Board of Directors of the Company (or, if appropriate, any
committee administering the Company Stock Plans) shall adopt such resolutions or
take such other actions as may be required to effect the following:

         (i) adjust the terms of all outstanding Company Stock Options granted
     under the Company Stock Plans, whether vested or unvested, as necessary to
     provide that, at the Effective Time, each Company Stock Option outstanding
     immediately prior to the Effective Time shall be amended and converted into
     an option to acquire, on the same terms and conditions as were applicable
     under such Company Stock Option, the number of shares of Lucent Common
     Stock (rounded down to the nearest whole share) equal to (A) the number of
     shares of Company Common Stock subject to such Company Stock Option
     immediately prior to the Effective Time multiplied by (B) the Exchange
     Ratio, at an exercise price per share of Lucent Common Stock (rounded to
     the nearest one-hundredth of a cent) equal to (x) the exercise price per
     share of such Company Common Stock immediately prior to the Effective Time
     divided by (y) the Exchange Ratio (each, as so adjusted, an "Adjusted
     Option"); and

                                      A-32
<PAGE>   112

         (ii) make such other changes to the Company Stock Plans as the Company
     and Lucent may agree are appropriate to give effect to the Merger,
     including as provided in Section 5.7.

     (b) As soon as practicable after the Effective Time, Lucent shall deliver
to the holders of Company Stock Options appropriate notices setting forth such
holders' rights pursuant to the respective Company Stock Plans and the
agreements evidencing the grants of such Company Stock Options and that such
Company Stock Options and agreements shall be assumed by Lucent and shall
continue in effect on the same terms and conditions (subject to the adjustments
required by this Section 5.6 after giving effect to the Merger).

     (c) A holder of an Adjusted Option may exercise such Adjusted Option in
whole or in part in accordance with its terms by delivering a properly executed
notice of exercise to Lucent, together with the consideration therefor and
applicable withholding taxes.

     (d) Except as otherwise contemplated by this Section 5.6 and except to the
extent required under the respective terms of the Company Stock Options, all
restrictions or limitations on transfer and vesting with respect to Company
Stock Options awarded under the Company Stock Plans or any other plan, program
or arrangement of the Company or any of its Subsidiaries, to the extent that
such restrictions or limitations shall not have already lapsed, shall remain in
full force and effect with respect to such options after giving effect to the
Merger and the assumption by Lucent as set forth above.

     5.7. Company Stock Plans.   At the Effective Time, by virtue of the Merger,
the Company Stock Plans and the Company Stock Options granted thereunder shall
be assumed by Lucent, with the result that all obligations of the Company under
the Company Stock Plans, including with respect to awards outstanding at the
Effective Time under each Company Stock Plan, shall be obligations of Lucent
following the Effective Time; provided, that in the case of any Company Stock
Option to which Section 421 of the Code applies by reason of its qualification
under Section 422 or Section 423 of the Code, the option price, number of shares
purchasable pursuant to such Company Stock Option and the terms and conditions
of exercise of such Company Stock Option shall be determined in order to comply
with Section 424 of the Code. Prior to the Effective Time, Lucent shall take all
necessary actions (including, if required to comply with Section 162(m) of the
Code (and the regulations thereunder) or applicable law or rule of the NYSE,
obtaining the approval of its stockholders at the next regularly scheduled
annual meeting of Lucent following the Effective Time) for the assumption of the
Company Stock Plans, including the reservation, issuance and listing of Lucent
Common Stock in a number at least equal to the number of shares of Lucent Common
Stock that will be subject to the Adjusted Options. As soon as practicable
following the Effective Time, Lucent shall prepare and file with the SEC a
registration statement on Form S-8 (or another appropriate form) registering a
number of shares of Lucent Common Stock determined in accordance with the
preceding sentence. Such registration statement shall be kept effective (and the
current status of the prospectus or

                                      A-33
<PAGE>   113

prospectuses required thereby shall be maintained) at least for so long as the
Adjusted Options or any unsettled awards granted under the Company Stock Plans
after the Effective Time remain outstanding.

     5.8. Employee Benefit Plans; Existing Agreement.   (a) As soon as
practicable after the Effective Time (the "Benefits Date"), Lucent shall
provide, or cause to be provided, employee benefit plans, programs and
arrangements to employees of the Company that are the same as those made
generally available to non-represented employees of Lucent who are hired by
Lucent after December 31, 1999. From the Effective Time to the Benefits Date
(which the parties acknowledge may occur on different dates with respect to
different plans, programs or arrangements of the Company) (the "Continuation
Period"), Lucent shall provide, or cause to be provided, the employee benefit
plans, programs and arrangements of the Company provided to employees of the
Company as of the date hereof.

     (b) With respect to each benefit plan, program, practice, policy or
arrangement maintained by Lucent (the "Lucent Plans") in which employees of the
Company subsequently participate, for purposes of determining vesting and
entitlement to benefits, including for severance benefits and vacation
entitlement (but not for accrual of pension benefits), service with the Company
(or predecessor employers to the extent the Company provides past service
credit) shall be treated as service with Lucent; provided, that such service
shall not be recognized to the extent that such recognition would result in a
duplication of benefits. Such service also shall apply for purposes of
satisfying any waiting periods, evidence of insurability requirements, or the
application of any pre-existing condition limitations. Each Lucent Plan shall
waive pre-existing condition limitations to the same extent waived under the
applicable Company Benefit Plan. Company Employees shall be given credit for
amounts paid under a corresponding benefit plan during the same period for
purposes of applying deductibles, copayments and out-of-pocket maximums as
though such amounts had been paid in accordance with the terms and conditions of
the Lucent Plan for the plan year in which the Effective Time occurs.

     5.9. Indemnification.   (a) From and after the Effective Time, Lucent
shall, or shall cause the Surviving Corporation to, fulfill and honor in all
respects (i) the obligations of the Company to indemnify each Person who is or
was a director or officer (an "Indemnified Party") of the Company or any of its
Subsidiaries pursuant to any indemnifications provision of the Company's
Certificate of Incorporation or By-laws as each is in effect on the date hereof
and (ii) any indemnification agreements of the Company listed in Item 5.9(a) of
the Company Disclosure Schedule (as each is in effect on the date hereof), the
existence of which does not constitute a breach of this Agreement, shall be
assumed by the Surviving Corporation in the Merger, without further action, as
of the Effective Time and shall survive the Merger and shall continue in full
force and effect in accordance with their terms, and Lucent shall cause the
Surviving Corporation to honor all such rights.

     (b) For a period of six years after the Effective Time, Lucent shall cause
to be maintained in effect the current officers' and directors' liability
insurance maintained by

                                      A-34
<PAGE>   114

the Company with respect to the Indemnified Parties (provided that Lucent may
substitute therefor policies of at least the same coverage and amounts
containing terms and conditions which are no less advantageous to the
Indemnified Parties than such existing insurance) covering acts or omissions
occurring prior to the Effective Time; provided, that Lucent shall not be
required in order to maintain or procure such coverage to pay an annual premium
in excess of 200% of the current annual premium paid by the Company for its
existing coverage (the "Cap"); and provided, further, that if existing coverage
cannot be maintained or equivalent coverage cannot be obtained, or can be
obtained only by paying an annual premium in excess of the Cap, Lucent shall
only be required to obtain as much coverage as can be obtained by paying an
annual premium equal to the Cap. The current annual premium paid by the Company
for its existing coverage is set forth in Item 5.9(b) of the Company Disclosure
Schedule.

     (c) This Section 5.9 shall survive the closing of all the transactions
contemplated hereby, is intended to benefit the Indemnified Parties and their
respective heirs and personal representative (each of which shall be entitled to
enforce this Section 5.9 against Lucent and the Surviving Corporation, as the
case may be, as a third-party beneficiary of this Agreement).

     5.10. Fees and Expenses.   (a) Except as provided in this Section 5.10, all
fees and expenses incurred in connection with the Merger, this Agreement, the
Option Agreement and the transactions contemplated by this Agreement and the
Option Agreement shall be paid by the party incurring such fees or expenses,
whether or not the Merger is consummated, except that each of Lucent and the
Company shall bear and pay one-half of (i) the costs and expenses incurred in
connection with the filing, printing and mailing of the Lucent Registration
Statement, the Company Proxy Statement (including SEC filing fees) and (ii) the
filing fees for the pre-merger notification and report forms under the HSR Act.

     (b) In the event that (i) a bona fide Takeover Proposal shall have been
made directly to the stockholders of the Company generally or shall have
otherwise become publicly known or any Person shall have publicly announced an
intention (whether or not conditional) to make a Takeover Proposal and
thereafter this Agreement is terminated by either Lucent or the Company pursuant
to Section 10(b)(i) or 10(c), or (ii) this Agreement is terminated by the
Company pursuant to Section 10(e) or (iii) this Agreement is terminated by
Lucent pursuant to Section 10(d), then the Company shall promptly, but in no
event later than the date of such termination, pay Lucent a fee equal to $90
million (the "Termination Fee"), payable by wire transfer of same day funds;
provided, that no Termination Fee shall be payable to Lucent pursuant to clause
(i) of this Section 5.10(b) unless within nine (9) months of such termination
the Company or any of its Subsidiaries enters into any definitive agreement with
respect to, or consummates, any Takeover Proposal. The Company acknowledges that
the agreements contained in this Section 5.10(b) are an integral part of the
transactions contemplated by this Agreement and that, without these agreements,
Lucent would not enter into this Agreement. Accordingly, if the Company fails
promptly to pay the amount due pursuant to this Section 5.10(b), and, in order
to obtain such payment,

                                      A-35
<PAGE>   115

Lucent commences a suit which results in a judgment against the Company for the
fee set forth in this Section 5.10(b), the Company shall pay to Lucent its costs
and expenses (including attorneys' fees and expenses) in connection with such
suit, together with interest on the amount of the fee at the prime rate of
Citibank, N.A. in effect on the date such payment was required to be made.

     5.11.   Public Announcements.   Lucent and the Company will consult with
each other before issuing, and provide each other the opportunity to review,
comment upon and concur with, any press release or other public statements with
respect to the transactions contemplated by this Agreement, including the Merger
and the Option Agreement, and shall not issue any such press release or make any
such public statement prior to such consultation, except as either party may
determine is required by applicable law, court process or by obligations
pursuant to any listing agreement with any national securities exchange or
national trading system. The parties agree that the initial press release to be
issued with respect to the transactions contemplated by this Agreement and the

     Company's representations and warranties contained in Section 2 of this
     Agreement shall be true and correct as of the date hereof and as of the
     Closing with the same effect as if made at and as of such time (except to

     date), except where the failure of such representations and warranties to
     be so true and correct (without giving effect to any limitation as to
     "materiality" or "Material Adverse Effect" set forth therein) does not
     have, and could not reasonably be expected to have, individually or in the
     aggregate, a Material Adverse Effect on the Company. Lucent and Acquisition
     shall have received a certificate dated the Closing Date and signed by the
     Chairman, President or a Vice-President of the Company, certifying that,

     Sidley & Austin, counsel to Lucent, on the date on which the Form S-4 is
     declared effective by the SEC and on the Closing Date, in each case dated

     facts, representations and assumptions set forth in such opinion, the
     Merger will be treated for federal income tax purposes as a reorganization
     within the meaning of Section 368(a) of the Code. In rendering such
     opinion, such counsel shall be entitled to rely upon representation letters
     signed by officers of Lucent, Acquisition and the Company substantially in
     the forms attached as Exhibits D-1 and D-2 to this Agreement.

         (c) Non-Disclosure and Non-Competition Agreements.   Each of the

     6.3.   Conditions Precedent to the Company's Obligations.   All obligations
of the Company under this Agreement are subject to the fulfillment or
satisfaction, prior to or on the Closing Date, of each of the following
additional conditions precedent:

         (a) Performance of Obligations; Representations and
     Warranties.   Acquisition and Lucent shall have performed and complied in
     all material respects with all agreements and conditions contained in this
     Agreement that are required to be performed or complied with by them prior
     to or at the Closing. Each of the representations and warranties of
     Acquisition and Lucent contained in Section 3 of this Agreement shall be
     true and correct as of the date hereof and as of the Closing with the same
     effect as if made at and as of such time (except to the extent expressly
     made as of an earlier date, in which case as of such date), except where
     the failure of such representations and warranties to be so true and
     correct (without giving effect to any limitation as to "materiality" or
     "Material Adverse Effect" set forth therein) does not have, and could not
     reasonably be expected to have, individually or in the aggregate, a
     Material Adverse Effect on Lucent. The Company shall have received
     certificates dated the Closing Date and signed by the President or a
     Vice-President of Acquisition and an authorized signatory of Lucent,
     certifying that the conditions specified in this Section 6.3(a) have been

         (b) Tax Opinion.   The Company shall have received a written opinion
     from Latham & Watkins, counsel to the Company, on the date on which the
     Form S-4 is declared effective by the SEC and on the Closing Date, in each
     case dated as of such respective date, to the effect that on the basis of
     certain facts, representations and assumptions set forth in such opinion,
     the Merger will be treated for federal income tax purposes as a
     reorganization within the meaning of Section 368(a) of the Code. In
     rendering such opinion, such counsel shall be entitled to rely upon
     representation letters signed by officers of Lucent, Acquisition and the
     Company substantially in the forms attached as Exhibits D-1 and D-2 to this
     Agreement.

     6.4   Frustration of Closing Conditions.   None of the Company, Lucent or
Acquisition may rely on the failure of any condition set forth in Sections 6.1,
6.2 or 6.3, as the case may be, to be satisfied if such failure was caused by
such party's failure to use reasonable efforts to consummate the Merger and the
other transactions contemplated by this Agreement and the Option Agreement, as
required by and subject to Section 5.5

     7.   Non-Survival of Representation and Warranties.   None of the
representations and warranties in this Agreement or in any instrument delivered
pursuant to this Agreement shall survive the Effective Time. This Section shall
not limit any covenant or agreement by the parties which expressly requires
performance after the Effective Time.

the agreements referred to or contemplated herein and the letter agreement dated
January 10, 2000, concerning confidentiality (the "Confidentiality Agreement")

written notice to the Company if the assignee shall assume the obligations of
Acquisition hereunder and Lucent shall remain liable for its obligations
hereunder. All the terms and provisions of this Agreement shall be binding upon
and inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto.

     10.   Termination.   This Agreement may be terminated, and the Merger may

     occur on or before such date; or (ii) any court of competent jurisdiction
     in the United States or other United States governmental authority shall

                                                                         ANNEX B

                             STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT dated as of February 7, 2000 (this "Agreement"), by
and between ORTEL CORPORATION, a Delaware corporation ("Issuer"), and LUCENT
TECHNOLOGIES INC., a Delaware corporation ("Grantee").

                                    RECITALS

     A.   Grantee, Solara Acquisition Inc., a wholly owned subsidiary of Grantee
("Acquisition"), and Issuer have entered into an Agreement and Plan of Merger
dated as of the date hereof (the "Merger Agreement"; defined terms used but not
defined herein have the respective meanings set forth in the Merger Agreement),
providing for, among other things, the merger of Acquisition with and into
Issuer, with Issuer as the surviving corporation in the Merger and becoming a
wholly owned subsidiary of Grantee; and

     B.   As a condition and inducement to Grantee's willingness to enter into
the Merger Agreement, Grantee has requested that Issuer agree, and Issuer has
agreed, to grant Grantee the Option (as defined below).

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, Issuer
and Grantee agree as follows:

     1.   Grant of Option.   Subject to the terms and conditions set forth
herein, Issuer hereby grants to Grantee an irrevocable option (the "Option") to
purchase up to 2,550,041 (as adjusted as set forth herein) shares (the "Option
Shares") of common stock, par value $.001 per share ("Issuer Common Stock"), of
Issuer at a purchase price of $177.125 (as adjusted as set forth herein) per
Option Share (the "Purchase Price").

     2.   Exercise of Option.   (a) Grantee may exercise the Option, with
respect to any or all of the Option Shares at any time or times, subject to the
provisions of Section 2(c), after the occurrence of any event as a result of
which the Grantee is unconditionally entitled to receive the Termination Fee
pursuant to Section 5.10(b) of the Merger Agreement (a "Purchase Event");
provided, that (i) except as provided in the last sentence of this Section 2(a),
the Option will terminate and be of no further force and effect upon the
earliest to occur of (A) the Effective Time and (B) 15 months after the first
occurrence of a Purchase Event, and (ii) any purchase of Option Shares upon
exercise of the Option will be subject to compliance with the HSR Act and the
obtaining or making of any consents, approvals, orders, notifications, filings
or authorizations, the failure of which to have obtained or made would have the
effect of making the issuance of Option Shares to Grantee illegal (the
"Regulatory Approvals"). Notwithstanding the termination of the Option, Grantee
will be entitled to purchase the Option Shares if it has exercised the Option in
accordance with the terms hereof prior to the termination of the Option and the
termination of the Option will not affect any rights

                                       B-1
<PAGE>   129

hereunder which by their terms do not terminate or expire prior to or as of such
termination.

     (b) In the event that Grantee is entitled to and wishes to exercise the
Option, it will send to Issuer a written notice (an "Exercise Notice"; the date
of such notice being herein referred to as the "Notice Date") to that effect
which Exercise Notice also specifies the number of Option Shares, if any,
Grantee wishes to purchase pursuant to this Section 2(b), the denominations of
the certificate or certificates evidencing the Option Shares which Grantee
wishes to purchase pursuant to this Section 2(b) and a date (an "Option Closing
Date"), subject to the following sentence, not earlier than seven business days
nor later than 20 business days from the Notice Date for the closing of such
purchase (an "Option Closing"). Any Option Closing will be at an agreed location
and time in New York, New York on the applicable Option Closing Date or at such
later date as may be necessary so as to comply with the first sentence of
Section 2(a).

     (c) Notwithstanding anything to the contrary contained herein, any exercise
of the Option and purchase of Option Shares shall be subject to compliance with
applicable laws and regulations, which may prohibit the purchase of all the
Option Shares specified in the Exercise Notice without first obtaining or making
certain Regulatory Approvals. In such event, if the Option is otherwise
exercisable and Grantee wishes to exercise the Option, the Option may be
exercised in accordance with Section 2(b) and Grantee shall acquire the maximum
number of Option Shares specified in the Exercise Notice that Grantee is then
permitted to acquire under the applicable laws and regulations, and if Grantee
thereafter obtains the Regulatory Approvals to acquire the remaining balance of
the Option Shares specified in the Exercise Notice, then Grantee shall be
entitled to acquire such remaining balance. Issuer agrees to use its reasonable
best efforts (as defined in the Merger Agreement) to assist Grantee in seeking
the Regulatory Approvals.

     In the event (i) Grantee receives official notice that a Regulatory
Approval required for the purchase of any Option Shares will not be issued or
granted or (ii) such Regulatory Approval has not been issued or granted within
six months of the date of the Exercise Notice, then with respect to the number
of Option Shares for which such Regulatory Approval will not be issued or
granted or has not been issued or granted, Grantee shall have the right to
exercise its Cash-Out Right pursuant to Section 6(c) with respect to such number
of Option Shares for which such Regulatory Approval will not be issued or
granted or has not been issued or granted.

     3.   Payment and Delivery of Certificates.   (a) At any Option Closing,
Grantee will pay to Issuer in immediately available funds by wire transfer to a
bank account designated in writing by Issuer an amount equal to the Purchase
Price multiplied by the number of Option Shares to be purchased at such Option
Closing plus the amount of any transfer, stamp or other similar taxes or charges
imposed in connection therewith.

     (b) At any Option Closing, simultaneously with the delivery of immediately
available funds as provided in Section 3(a), Issuer will deliver to Grantee a
certificate or certificates representing the Option Shares to be purchased at
such Option Closing,

                                       B-2
<PAGE>   130

which Option Shares will be free and clear of all liens, claims, charges and
encumbrances of any kind whatsoever. If at the time of issuance of Option Shares
pursuant to an exercise of the Option hereunder, Issuer shall have issued any
securities similar to rights under a stockholder rights plan, then each Option
Share issued pursuant to such exercise will also represent such a corresponding
right with terms substantially the same as and at least as favorable to Grantee
as are provided under any such stockholder rights plan then in effect.

     (c) Certificates for the Option Shares delivered at an Option Closing will
have typed or printed thereon a restrictive legend which will read substantially
as follows:

    "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
    UNDER THE SECURITIES ACT OF 1933 AND MAY BE REOFFERED OR SOLD ONLY IF SO
    REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE. SUCH
    SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET
    FORTH IN THE STOCK OPTION AGREEMENT DATED AS OF FEBRUARY 7, 2000, A COPY OF
    WHICH MAY BE OBTAINED FROM THE SECRETARY OF ORTEL CORPORATION AT ITS
    PRINCIPAL EXECUTIVE OFFICES."

It is understood and agreed that (i) the reference to restrictions arising under
the Securities Act in the above legend will be removed by delivery of substitute
certificate(s) without such reference if such Option Shares have been registered
pursuant to the Securities Act, such Option Shares have been sold in reliance on
and in accordance with Rule 144 under the Securities Act or Grantee has
delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion
of counsel in form and substance reasonably satisfactory to Issuer and its
counsel, to the effect that such legend is not required for purposes of the
Securities Act and (ii) the reference to restrictions pursuant to this Agreement
in the above legend will be removed by delivery of substitute certificate(s)
without such reference if the Option Shares evidenced by certificate(s)
containing such reference have been sold or transferred in compliance with the
provisions of this Agreement under circumstances that do not require the
retention of such reference.

     4.   Representations and Warranties of Issuer.   Issuer hereby represents
and warrants to Grantee as follows:

         Authorized Stock.   Issuer has taken all necessary corporate and other
     action to authorize and reserve and, subject to the expiration or
     termination of any required waiting period under the HSR Act, to permit it
     to issue, and, at all times from the date hereof until the obligation to
     deliver Option Shares upon the exercise of the Option terminates, shall
     have reserved for issuance, upon exercise of the Option, shares of Issuer
     Common Stock necessary for Grantee to exercise the Option, and Issuer will
     take all necessary corporate action to authorize and reserve for issuance
     all additional shares of Issuer Common Stock or other securities which may
     be issued pursuant to Section 6 upon exercise of the Option. The shares of
     Issuer Common Stock to be issued upon due exercise of the Option, including
     all

                                       B-3
<PAGE>   131

     additional shares of Issuer Common Stock or other securities which may be
     issuable upon exercise of the Option or any other securities which may be
     issued pursuant to Section 6, upon issuance pursuant hereto, will be duly
     and validly issued, fully paid and nonassessable, and will be delivered
     free and clear of all liens, claims, charges and encumbrances of any kind
     or nature whatsoever, including without limitation any preemptive rights of
     any stockholder of Issuer.

     5.   Representations and Warranties of Grantee.   Grantee hereby represents
and warrants to Issuer that:

         Purchase Not for Distribution.   Any Option Shares or other securities
     acquired by Grantee upon exercise of the Option will not be transferred or
     otherwise disposed of except in a transaction registered, or exempt from
     registration, under the Securities Act.

     6.   Adjustment upon Changes in Capitalization, Etc.   (a) In the event of
any change in Issuer Common Stock by reason of a stock dividend, split-up,
merger, recapitalization, combination, exchange of shares, or similar
transaction, the type and number of shares or securities subject to the Option,
and the Purchase Price thereof, will be adjusted appropriately, and proper
provision will be made in the agreements governing such transaction, so that
Grantee will receive upon exercise of the Option the number and class of shares
or other securities or property that Grantee would have received in respect of
Issuer Common Stock if the Option had been exercised immediately prior to such
event or the record date therefor, as applicable. Subject to Section 1, and
without limiting the parties' relative rights and obligations under the Merger
Agreement, if any additional shares of Issuer Common Stock are issued after the
date of this Agreement (other than pursuant to an event described in the first
sentence of this Section 6(a)), the number of shares of Issuer Common Stock
subject to the Option will be adjusted so that, after such issuance, it equals
19.9% of the number of shares of Issuer Common Stock then issued and
outstanding, without giving effect to any shares subject to or issued pursuant
to the Option.

     (b) Without limiting the parties' relative rights and obligations under the
Merger Agreement, in the event that Issuer enters into an agreement (i) to
consolidate with or merge into any person, other than Grantee or one of its
subsidiaries, and Issuer will not be the continuing or surviving corporation in
such consolidation or merger, (ii) to permit any person, other than Grantee or
one of its subsidiaries, to merge into Issuer and Issuer will be the continuing
or surviving corporation, but in connection with such merger, the shares of
Issuer Common Stock outstanding immediately prior to the consummation of such
merger will be changed into or exchanged for stock or other securities of Issuer
or any other person or cash or any other property, or the shares of Issuer
Common Stock outstanding immediately prior to the consummation of such merger
will, after such merger, represent less than 50% of the outstanding voting
securities of the merged company, or (iii) to sell or otherwise transfer all or
substantially all of its assets to any person, other than Grantee or one of its
subsidiaries, then, and in each such case, the agreement governing such
transaction will make proper provision so that the Option will, upon the
consummation of any such transaction and upon the terms and conditions set

                                       B-4
<PAGE>   132

forth herein, be converted into, or exchanged for, an option with identical
terms appropriately adjusted to acquire the number and class of shares or other
securities or property that Grantee would have received in respect of Issuer
Common Stock if the Option had been exercised immediately prior to such
consolidation, merger, sale, or transfer, or the record date therefor, as
applicable and make any other necessary adjustments.

     (c) If at any time during the period commencing on a Purchase Event and
ending on the termination of the Option in accordance with Section 2, Grantee
sends to Issuer an Exercise Notice indicating Grantee's election to exercise its
right (the "Cash-Out Right") pursuant to this Section 6(c), then Issuer shall
pay to Grantee on the Option Closing Date, in exchange for the cancellation of
the Option with respect to such number of Option Shares as Grantee specifies in
the Exercise Notice, an amount in cash equal to such number of Option Shares
multiplied by the difference between (i) the average closing price, for the 10
trading days commencing on the 12th trading day immediately preceding the Option
Closing Date, per share of Issuer Common Stock as reported on The Nasdaq
National Market (or, if not listed on The Nasdaq National Market, as reported on
any other national securities exchange or national securities quotation system
on which the Issuer Common Stock is listed or quoted, as reported in The Wall
Street Journal (Northeast edition), or, if not reported thereby, any other
authoritative source) (the "Closing Price") and (ii) the Purchase Price.
Notwithstanding the termination of the Option, Grantee will be entitled to
exercise its rights under this Section 6(c) if it has exercised such rights in
accordance with the terms hereof prior to the termination of the Option.

     (d) (i) Notwithstanding any other provision of this Agreement, in no event
shall Grantee's Total Profit (as hereinafter defined) plus any Termination Fee
paid to Grantee pursuant to Section 5.10(b) of the Merger Agreement exceed in
the aggregate $105 million and, if the total amount that otherwise would be
received by Grantee would exceed such amount, Grantee, at its election, shall
either (a) reduce the number of shares of Issuer Common Stock subject to the
Option, (b) deliver to Issuer for cancellation shares of Issuer Common Stock
previously purchased by Grantee, (c) pay cash to Issuer or (d) take any action
representing any combination of the preceding clauses (a), (b) and (c), so that
Grantee's actually realized Total Profit, when aggregated with such Termination
Fee so paid to Grantee, shall not exceed $105 million after taking into account
the foregoing actions.

     (ii) Notwithstanding any other provision of this Agreement, the Option may
not be exercised for a number of Option Shares as would, as of the date of
exercise, result in a Notional Total Profit (as defined below) which, together
with any Termination Fee theretofore paid to Grantee, would exceed $105 million;
provided, that nothing in this sentence shall restrict any exercise of the
Option permitted hereby on any subsequent date.

     (iii) As used herein, the term "Total Profit" shall mean the aggregate
amount (before taxes) of the following: (A) the amount received by Grantee
pursuant to Issuer's repurchase of the Option (or any portion thereof) pursuant
to the exercise of the

                                       B-5
<PAGE>   133

Cash-Out Right under Section 6(c) and (B) the net cash amounts or the fair
market value of any property received by Grantee pursuant to the sale of Option
Shares (or other securities).

     (iv) As used herein, the term "Notional Total Profit" with respect to any
number of Option Shares as to which Grantee may propose to exercise the Option
shall be the Total Profit determined as of the date of such proposal assuming
for such purpose that the Option was exercised on such date for such number of
Option Shares and assuming that such Option Shares, together with all other
Option Shares held by Grantee and its affiliates as of such date, were sold for
cash at the closing market price on The Nasdaq National Market (or, if shares of
Issuer Common Stock are not then listed or traded on The Nasdaq National Market,
on any other national securities exchange or national quotation system on which
shares of Issuer Common Stock are so listed or traded) for shares of Issuer
Common Stock as of the close of business on the preceding trading day (less
customary brokerage commissions).

     7.   Registration Rights.   Issuer will, if requested by Grantee at any
time and from time to time within two years of the exercise of the Option, as
expeditiously as reasonably possible prepare and file up to three registration
statements under the Securities Act if such registration is necessary in order
to permit the sale or other disposition of any or all shares of securities that
have been acquired by or are issuable to Grantee upon exercise of the Option in
accordance with the intended method of sale or other disposition stated by
Grantee, including a "shelf" registration statement under Rule 415 under the
Securities Act or any successor provision, and Issuer will use its best efforts
to qualify such shares or other securities under any applicable state securities
laws. Grantee agrees to cause, and to cause any underwriters of any sale or
other disposition to cause, any sale or other disposition pursuant to such
registration statement to be effected on a widely distributed basis so that upon
consummation thereof no purchaser or transferee will own beneficially more than
3.0% of the then-outstanding voting power of Issuer. Issuer will use reasonable
efforts to cause each such registration statement to become effective, to obtain
all consents or waivers of other parties which are required therefor, and to
keep such registration statement effective for such period not in excess of 120
calendar days from the day such registration statement first becomes effective
as may be reasonably necessary to effect such sale or other disposition. The
obligations of Issuer hereunder to file a registration statement and to maintain
its effectiveness may be suspended for up to 120 calendar days in the aggregate
if the Board of Directors of Issuer shall have determined that the filing of
such registration statement or the maintenance of its effectiveness would
require premature disclosure of material nonpublic information that would
materially and adversely affect Issuer or otherwise interfere with or adversely
affect any pending or proposed offering of securities of Issuer or any other
material transaction involving Issuer. Any registration statement prepared and
filed under this Section 7, and any sale covered thereby, will be at Issuer's
expense except for underwriting discounts or commissions, brokers' fees and the
fees and disbursements of Grantee's counsel related thereto. Grantee will
provide all information reasonably requested by Issuer for inclusion in any
registration statement to be filed hereunder. If, during the time periods
referred to in the first sentence of this Section 7,

                                       B-6
<PAGE>   134

Issuer effects a registration under the Securities Act of Issuer Common Stock
for its own account or for any other stockholders of Issuer (other than on Form
S-4 or Form S-8, or any successor form), it will allow Grantee the right to
participate in such registration, and such participation will not affect the
obligation of Issuer to effect demand registration statements for Grantee under
this Section 7; provided that, if the managing underwriters of such offering
advise Issuer in writing that in their opinion the number of shares of Issuer
Common Stock requested to be included in such registration exceeds the number
which can be sold in such offering, Issuer will include the shares requested to
be included therein by Grantee pro rata with the shares intended to be included
therein by Issuer. In connection with any registration pursuant to this Section
7, Issuer and Grantee will provide each other and any underwriter of the
offering with customary representations, warranties, covenants, indemnification,
and contribution in connection with such registration.

     If a requested registration pursuant to this Section 7 involves an
underwritten offering, the underwriter or underwriters thereof shall be a
nationally recognized firm or firms selected by Issuer. Notwithstanding anything
else contained in this Section 7, each requested registration shall be for a
number of shares of Issuer Common Stock which represent at least one-fourth of
the total of number of shares of Issuer Common Stock purchased by Grantee
hereunder.

     8.   Transfers.   The Option Shares may not be sold, assigned, transferred,
or otherwise disposed of except (i) in an underwritten public offering as
provided in Section 7 or (ii) to any purchaser or transferee who would not, to
the knowledge of Grantee after reasonable inquiry (which shall include obtaining
a representation from the purchaser or transferee), immediately following such
sale, assignment, transfer or disposal, beneficially own more than 3.0% of the
then-outstanding voting power of the Issuer; provided, that Grantee shall be
permitted to sell any Option Shares if such sale is made pursuant to a tender or
exchange offer that has been approved or recommended by a majority of the
members of the Board of Directors of Issuer (which majority shall include a
majority of directors who were directors as of the date hereof).

     9.   Listing.   If Issuer Common Stock or any other securities to be
acquired upon exercise of the Option are then listed on The Nasdaq National
Market (or any other national securities exchange or national securities
quotation system), Issuer, upon the request of Grantee, will promptly file an
application to list the shares of Issuer Common Stock or other securities to be
acquired upon exercise of the Option on The Nasdaq National Market (and any such
other national securities exchange or national securities quotation system) and
will use reasonable efforts to obtain approval of such listing as promptly as
practicable.

     10.   Loss or Mutilation.   Upon receipt by Issuer of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered will constitute an
additional contractual obligation on the part of Issuer, whether or not the

                                       B-7
<PAGE>   135

Agreement so lost, stolen, destroyed, or mutilated shall at any time be
enforceable by anyone.

     11.   Miscellaneous.   (a) Expenses.   Each of the parties hereto will bear
and pay all costs and expenses incurred by it or on its behalf in connection
with the transactions contemplated hereunder, including fees and expenses of its
own financial consultants, investment bankers, accountants, and counsel.

     (b)   Amendment.   This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

     (c)   Extension; Waiver.   Any agreement on the part of a party to waive
any provision of this Agreement, or to extend the time for performance, will be
valid only if set forth in an instrument in writing signed on behalf of such
party. The failure of any party to this Agreement to assert any of its rights
under this Agreement or otherwise will not constitute a waiver of such rights.

     (d)   Entire Agreement; No Third-Party Beneficiaries.   This Agreement, the
Merger Agreement (including the documents and instruments attached thereto as
exhibits or schedules or delivered in connection therewith) and the
Confidentiality Agreement (i) constitute the entire agreement, and supersede all
prior agreements and understandings, both written and oral, between the parties
with respect to the subject matter of this Agreement, and (ii) are not intended
to confer upon any person other than the parties any rights or remedies.

     (e)   Governing Law.   This Agreement will be governed by, and construed in
accordance with, the laws of the State of New York, regardless of the laws that
might otherwise govern under applicable principles of conflict of laws thereof.

     (f)   Notices.   All notices, requests, claims, demands, and other
communications under this Agreement shall be sent in the manner and to the
addresses set forth in the Merger Agreement.

     (g)   Assignment.   Neither this Agreement, the Option nor any of the
rights, interests, or obligations under this Agreement may be assigned or
delegated, in whole or in part, by operation of law or otherwise, by Issuer or
Grantee without the prior written consent of the other. Any assignment or
delegation in violation of the preceding sentence will be void. Subject to the
first and second sentences of this Section 11(g), this Agreement will be binding
upon, inure to the benefit of, and be enforceable by, the parties and their
respective successors and assigns.

     (h)   Further Assurances.   In the event of any exercise of the Option by
Grantee, Issuer and Grantee will execute and deliver all other documents and
instruments and take all other actions that may be reasonably necessary in order
to consummate the transactions provided for by such exercise.

     (i)   Enforcement.   The parties agree that irreparable damage would occur
and that the parties would not have any adequate remedy at law in the event that
any of the provisions of this Agreement were not performed in accordance with
their specific terms or were otherwise breached. It is accordingly agreed that
the parties will be entitled to

                                       B-8
<PAGE>   136

an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions of this Agreement in any Federal
court located in the State of New York or in New York state court, the foregoing
being in addition to any other remedy to which they are entitled at law or in
equity. In addition, each of the parties hereto (i) consents to submit itself to
the personal jurisdiction of any Federal court located in the State of New York
or any New York state court in the event any dispute arises out of this
Agreement or any of the transactions contemplated by this Agreement, (ii) agrees
that it will not attempt to deny or defeat such personal jurisdiction by motion
or other request for leave from any such court, and (iii) agrees that it will
not bring any action relating to this Agreement or any of the transactions
contemplated by this Agreement in any court other than a Federal court sitting
in the State of New York or a New York state court.

     (j)   Severability.   If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible to the fullest extent
permitted by applicable law in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the extent possible.

     IN WITNESS WHEREOF, Issuer and Grantee have caused this Agreement to be
signed by their respective officers thereunto duly authorized as of the day and
year first written above.

                  OPINION OF SOUNDVIEW TECHNOLOGY GROUP, INC.

                                               [SOUNDVIEW TECHNOLOGY GROUP LOGO]

February 6, 2000
Board of Directors
Ortel Corporation
2015 West Chestnut Street
Alhambra, CA 91803

Gentlemen:

     We understand that Lucent Technologies, Inc. ("Lucent"), Solara Acquisition
Inc. ("Merger Sub"), a wholly owned subsidiary of Lucent, and Ortel Corporation
(the "Company") are entering into an agreement and plan of merger (the "Merger
Agreement") substantially in the form of the draft dated February 4, 2000 (the
"Draft Merger Agreement") pursuant to which, among other things, Merger Sub
shall be merged with and into the Company in a transaction (the "Merger") in
which each share of common stock, par value $.001 per share, of the Company (the
"Company Common Stock"), subject to the conditions and limitations set forth in
the Draft Merger Agreement, shall be converted into the right to receive 3.1350
shares (the "Exchange Ratio") of the common stock, par value $.01 per share, of
Lucent. The terms and conditions of the Merger are set forth in more detail in
the Draft Merger Agreement, a copy of which has been furnished to us.

     You have requested the opinion of SoundView Technology Group, Inc.
("SoundView"), as investment bankers, as of this date, as to the fairness, from
a financial point of view, to the holders of the Company Common Stock (other
than Lucent, its affiliates and subsidiaries), of the Exchange Ratio.

     In conducting our analysis and arriving at our opinion as expressed herein,
we have, among other things:

         (i) reviewed the Draft Merger Agreement and the specific terms of the
     Merger set forth therein, and have assumed that the Merger Agreement will
     not vary in any regard that is material to our analysis;

         (ii) reviewed the Company's financial and operating information for the
     three year period ended April 30, 1999 and the six-month period ended
     October 31, 1999;

         (iii) reviewed Lucent's financial and operating information for the
     three year period ended December 31, 1999;

         (iv) reviewed certain financial and operating information regarding the
     businesses, operations and prospects of the Company, including forecasts
     and projections, provided to us by the management of the Company;

         (v) reviewed certain financial and operating information regarding the
     businesses, operations and prospects of Lucent, including forecasts and
     projections,

                                       C-1
<PAGE>   138

     published and disseminated by stock market research analysts who follow
     Lucent (internal financial forecasts and projections prepared by Lucent
     were not made available for our review);

         (vi) reviewed certain publicly available financial information
     concerning certain other companies we deemed to be reasonably similar to
     the Company and Lucent and the trading markets for certain of such
     companies' securities;

         (vii) reviewed the financial terms of the Merger and compared them with
     the financial terms, to the extent publicly available, of certain recent
     mergers and acquisitions that we deemed relevant; and

         (viii) performed such other analyses, examinations and procedures,
     reviewed such other agreements and documents, and considered such other
     factors as we have deemed, in our sole judgment, to be necessary,
     appropriate or relevant to render the opinion set forth herein.

     We have also taken into account our assessment of general economic, market
and financial conditions and our experience in similar transactions, as well as
our experience in securities valuation in general. Our opinion is necessarily
based upon economic, market, financial and other conditions as they exist and
can be evaluated on the date hereof and we assume no responsibility to update or
revise our opinion based upon events or circumstances occurring after the date
hereof. We reserve, however, the right to withdraw, revise or modify our opinion
based upon additional information which may be provided to or obtained by us,
which suggests, in our judgment, a material change in the assumptions upon which
our opinion is based.

     In arriving at our opinion, we have not made, obtained or assumed any
responsibility for, any independent evaluation or appraisal of the properties
and facilities or of the assets and liabilities (contingent or otherwise) of any
of the Company, Lucent or their respective subsidiaries. We have assumed and
relied upon the accuracy and completeness of the financial and other information
supplied to or otherwise used by us in arriving at our opinion and have not
attempted independently to verify, or undertaken any obligation to verify, such
information. We have further relied upon the assurances of the management of the
Company that they were not aware of any facts that would make such information
inaccurate or misleading. In addition, we have assumed that the forecasts and
projections provided to SoundView by the Company and reviewed by SoundView
represent the best currently available estimates and judgments of the Company's
management as to the future financial condition and results of operations of the
Company, and have assumed that such forecasts and projections have been
reasonably prepared based on such currently available estimates and judgments.
We assume no responsibility for and express no view as to such forecasts and
projections or the assumptions on which they are based.

     We do not express any opinion as to the price at which Lucent's stock will
trade prior to or subsequent to the closing of the Merger. This letter does not
constitute a recommendation of the Merger over any other alternative
transactions which may be available to the Company, does not address the
underlying business decision of the

                                       C-2
<PAGE>   139

Board of Directors of the Company to proceed with or effect the Merger or
constitute a recommendation to the stockholders of the Company as to how such
stockholders should vote or as to any other action such stockholders should take
regarding the Merger.

     SoundView, as part of its investment banking services, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, divestitures, restructurings, recapitalizations, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. We have been
engaged to render the financial opinion as expressed herein and we will receive
a fee upon delivery of this opinion. We also, from time to time, may in the
future perform certain financial advisory services for the Company for which we
may receive a fee. In the ordinary course of business, we may actively trade the
securities of Lucent or the Company for our own account and for the accounts of
our customers and, accordingly, may at any time hold a short or long position in
such securities. The Company has agreed to indemnify us for certain liabilities
that may arise out of the rendering of this opinion.

     This letter and the opinion expressed herein has been prepared for the
confidential use and benefit of the Board of Directors of the Company in its
consideration of the Merger, supersedes any previously rendered opinion and may
not be reproduced, summarized, described or referred to or given to any other
person or otherwise made public without our prior written consent, except the
Company may include this opinion in its entirety in any proxy statement or
information statement relating to the transaction sent to the Company's
stockholders.

     Based upon and subject to the foregoing, it is our opinion as investment
bankers that, as of the date hereof, the Exchange Ratio is fair, from a
financial point of view, to the holders of the Company Common Stock (other than
Lucent, its affiliates and subsidiaries).

                                      Very truly yours,

                                      /s/ SOUNDVIEW TECHNOLOGY GROUP, INC.

                                VOTING AGREEMENT

     THIS VOTING AGREEMENT dated as of February 7, 2000 (the "Agreement"), is
made by and among LUCENT TECHNOLOGIES INC., a Delaware corporation ("Lucent"),
SOLARA ACQUISITION INC., a Delaware corporation ("Acquisition"), and SUMITOMO
OSAKA CEMENT CO., LTD., a corporation organized under the laws of Japan
("Stockholder").

                             PRELIMINARY STATEMENTS

     Concurrently with the execution of this Agreement, Ortel Corporation, a
Delaware corporation (the "Company"), Lucent and Acquisition have entered into a
Agreement and Plan of Merger (as the same may be amended from time to time, the
"Merger Agreement"), providing for the merger of Acquisition with and into the
Company, with the Company being the surviving corporation (the "Merger"), which
Merger is subject to the approval of the holders of shares of capital stock of
the Company as provided in the Merger Agreement, the Delaware General
Corporation Law, as amended, and the Company's Certificate of Incorporation, as
amended.

     Stockholder owns 2,349,964 shares of the Company common stock, par value
$.001 per share (the "Common Stock"). As used herein, the term "Shares" includes
all shares of such Common Stock as to which Stockholder (at any time prior to
the termination of this Agreement) is the beneficial owner or is otherwise able
to direct the voting thereof and all securities issued or exchanges with respect
to any such Shares upon any reclassification, recapitalization, reorganization,
merger, consolidation, spin-off, stock split, combination, stock or other
dividend or any other change in the Company's capital structure.

     To induce Lucent and Acquisition to enter into the Merger Agreement, the
Company has agreed, upon the terms and subject to the conditions set forth
herein, to cause Stockholder to execute this Agreement.

     NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which are hereby acknowledged, the parties to this
Agreement agree as follows:

     1. Stockholder's Representations and Warranties.   Stockholder represents
and warrants to Lucent and Acquisition that (i) except as set forth in Schedule
1 hereto, Stockholder owns the Shares, as the case may be, free and clear of any
mortgage, pledge, lien, security interest, claim, restriction on voting or
otherwise or other encumbrance and (ii) Stockholder has the right to vote such
Shares free of any mortgage, pledge, lien, security interest, claim, restriction
on voting or otherwise or other encumbrance (other than any general fiduciary
obligation imposed by law).

     2. No Voting Trusts.   Stockholder hereby revokes any and all proxies and
voting instructions with respect to the Shares previously given by Stockholder
and Stockholder

                                       D-1
<PAGE>   141

agrees that it will not grant or give any other proxies or voting instructions
with respect to the voting of the Shares, enter into any voting trust or other
arrangement or agreement with respect to the voting of the Shares (and if given
or executed, such proxies, voting instructions, voting trust or other
arrangement or agreement shall not be effective), or agree, in any manner, to
vote the Shares for or against any proposal submitted to the stockholders of the
Company except in furtherance of the proposals set forth in paragraph 3 hereof.

     3. Agreements with Respect to the Shares.   (a) Stockholder agrees during
the term of this Agreement:

         (i) to vote the Shares, to the extent entitled to vote, (y) in favor of
     the approval of the Merger Agreement and the Merger, at every meeting of
     the stockholders of the Company at which such matters are considered and at
     every adjournment thereof and (z) with respect to all other proposals the
     approval or disapproval of which are, directly or indirectly, reasonably
     necessary to consummate the Merger, in such manner as Acquisition or Lucent
     may direct;

         (ii) not to solicit, encourage or recommend to other stockholders of
     the Company that (w) they vote their shares of Common Stock or any such
     other securities in any contrary manner, (x) they not vote their shares of
     Common Stock at all, (y) they tender, exchange or otherwise dispose of
     their shares of Common Stock pursuant to a Competing Transaction, as
     hereinafter defined, or (z) they attempt to exercise any statutory
     appraisal or other similar rights they may have; and

         (iii) to take such action as required on the part of Stockholder to
     satisfy conditions to closing set forth in the Merger Agreement including
     without limitation entering into any such agreements, arrangements or
     understandings contemplated by Section 6 thereof.

     (b) Unless otherwise instructed in writing by Lucent or Acquisition, during
the term of this Agreement, Stockholder will vote the Shares against any
Competing Transaction.

     (c) Except with the prior written consent of Lucent or Acquisition, during
the term of this Agreement, Stockholder agrees that Stockholder will not, and
shall use its reasonable best efforts not to permit any employee, attorney,
accountant, investment banker or other agent or representative of Stockholder to
initiate, solicit, negotiate, encourage, or provide confidential information in
order to facilitate, any Competing Transaction.

     (d) For purposes of this Agreement, a "Competing Transaction" shall mean a
transaction of any kind (including, without limitation, a merger, consolidation,
share exchange, reclassification, reorganization, recapitalization, sale or
encumbrance of substantially all the assets of the Company outside the ordinary
course of business, or sale or exchange by stockholders of the Company of all or
substantially all the shares of the Company's capital stock) proposed by any
person(s) in lieu of or in opposition to the Merger Agreement and the Merger.

                                       D-2
<PAGE>   142

     4. Proxies.   In furtherance of the foregoing, Stockholder is granting to
Richard Bleicher, the Vice President of Acquisition, and/or Paul Bento, the Vice
President and Secretary of Acquisition, or to his or her designee(s),
irrevocable proxies and powers of attorney (which may be in the form annexed
hereto or such other form consistent with the terms hereof and thereof as Lucent
or Acquisition may specify) to vote the Shares, to the extent such Shares are
entitled to vote, and hereby specifically agrees not to revoke such proxies
granted under any circumstances:

         (a) at any and all meetings of stockholders of the Company, notice of
     which meetings are given prior to the due and proper termination of this
     Agreement, with respect to matters presented to the Company's stockholders
     for vote which are, directly or indirectly, reasonably necessary to approve
     or disapprove (i) the Merger or the Merger Agreement; and (ii) any
     Competing Transaction; or

         (b) with respect to actions to be taken by written consent of the
     stockholders of the Company which, directly or indirectly, relates to or
     affects any of the foregoing, and which consent is solicited prior to the
     due and proper termination of this Agreement.

     5. Limitation on Sales.   During the term of this Agreement, except
pursuant to the Merger, Stockholder agrees not to sell, assign, transfer, loan,
tender, pledge, hypothecate, exchange, encumber or otherwise dispose of, or
issue an option or call with respect to, any of the Shares, or impair
Stockholder's Shares.

     6. Termination of Agreements.   Stockholder hereby consents to the
termination of the Key Shareholder Agreement dated as of March 26, 1990, among
the Company, Stockholder and certain other Key Shareholders described therein,
and the Agreement Concerning Certain Financing and Business Arrangements dated
as of March 26, 1990, between the Company and Stockholder, in each case as of
the Closing Date. Effective as of the Closing Date, Lucent hereby agrees to
cause the Surviving Corporation (as defined in the Merger Agreement) to continue
to comply with all of the terms and conditions of the International Distributor
and Selling Representative Agreement between the Company and Stockholder dated
as of July 1, 1995.

     7. Specific Performance.   Stockholder acknowledges that it will be
impossible to measure in money the damage to Lucent or Acquisition if
Stockholder fails to comply with the obligations imposed by this Agreement, and
that, in the event of any such failure, neither Lucent nor Acquisition will have
an adequate remedy at law or in damages. Accordingly, Stockholder agrees that
injunctive relief or any other equitable remedy, in addition to any remedies at
law or damages, is the appropriate remedy for any such failure and will not
oppose the granting of any such remedy on the basis that Lucent or Acquisition
has an adequate remedy at law. Stockholder agrees not to seek, and agrees to
waive any requirement for, the securing or posting of a bond in connection with
Lucent or Acquisition seeking or obtaining such equitable relief.

     8. Reasonable Efforts.   Stockholder will use all reasonable efforts to
cause to be satisfied the conditions to the obligations of the Company to effect
the Closing under the Merger Agreement.

                                       D-3
<PAGE>   143

     9. Publicity.   Stockholder agrees that, from the date hereof through the
Closing Date, Stockholder shall not issue any public release or announcement
concerning the transactions contemplated by this Agreement and the Merger
Agreement without the prior consent of Lucent, except (i) Stockholder may file
an amendment to its Schedule 13G originally filed with the Securities and
Exchange Commission on April 24, 1995, and (ii) as such release or announcement
may, in the opinion of Stockholder's counsel, be required by applicable law, in
which case Stockholder shall allow Lucent reasonable time to comment on such
release or announcement in advance of such issuance.

     10. Term of Agreement; Termination.

     (a) The term of this Agreement shall commence on the date hereof and shall
terminate upon the earliest to occur of (i) the Effective Time of the Merger (as
defined in the Merger Agreement) and (ii) the due and proper termination of the
Merger Agreement in accordance with its terms. Upon such termination, no party
shall have any further obligations or liabilities hereunder.

     (b) The obligations of Stockholder set forth in this Agreement shall not be
effective or binding upon Stockholder until after such time as the Merger
Agreement is executed and delivered by Lucent, Acquisition and the Company.

     11. Miscellaneous.   (a) Entire Agreement.   This Agreement constitutes the
entire agreement among the parties with respect to the subject matter of this
Agreement and supersedes all prior written and oral and all contemporaneous oral

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The registrant's certificate of incorporation provides that a director of
the registrant shall not be personally liable to the registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except, if required by the Delaware General Corporation Law, for liability (1)
for any breach of the director's duty of loyalty to the corporation or its
stockholders, (2) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (3) under Section 174 of
the Delaware General Corporation Law or (4) for any transaction from which the
director derived an improper personal benefit. Neither the amendment nor repeal
of such provision shall eliminate or reduce the effect of such provision in
respect of any matter occurring, or any cause of action, suit or claim that, but
for such provision, would accrue or arise prior to such amendment or repeal.

     While the registrant's certificate of incorporation provides directors with
protection from awards for monetary damages for breach of their duty of care, it
does not eliminate such duty. Accordingly, the registrant's certificate of
incorporation will have no effect on the availability of equitable remedies such
as an injunction or rescission based on a director's breach of his or her duty
of care.

     The registrant's certificate of incorporation provides that each person who
was or is made a party to or is threatened to be made a party to or is involved
in any action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), by reason of the fact that such
person, or a person of whom such person is the legal representative, is or was a
director or officer of the registrant or is or was serving at the request of the
registrant as a director, officer, employee or agent of another corporation or
of a partnership, joint venture, trust or other enterprise, including service
with respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a director, officer, employee or agent
or in any other capacity while serving as a director, officer, employee or
agent, shall be indemnified and held harmless by the registrant to the fullest
extent authorized by the Delaware General Corporation Law, as the same exists or
may hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the registrant to provide broader
indemnification rights than said law permitted the registrant to provide prior
to such amendment), against all expense, liability and loss reasonably incurred
or suffered by such person in connection therewith. Such right to
indemnification includes the right to have the registrant pay the expenses
incurred in defending any such proceeding in advance of its final disposition,
subject to the provisions of the Delaware General Corporation Law. Such rights
are not exclusive of any other right which any person may have or hereafter
acquire under any statute, provision of the registrant's certificate of
incorporation or by-laws, agreement, vote of stockholders or disinterested
directors or otherwise. No repeal or modification of such provision will in any
way diminish or adversely affect the rights of any director, officer, employee
or agent of the

                                      II-1
<PAGE>   149

registrant thereunder in respect of any occurrence or matter arising prior to
any such repeal or modification.

     The registrant's Certificate of Incorporation also specifically authorizes
the registrant to maintain insurance and to grant similar indemnification rights
to employees or agents of the registrant. The directors and officers of the
registrant are covered by insurance policies indemnifying them against certain
liabilities, including certain liabilities arising under the Securities Act of
1933, which might be incurred by them in such capacities.

ITEM 21.   EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

     (a) See Exhibit Index.

     (b) Not applicable.

     (c) Opinion of SoundView Technology Group, Inc., attached as Annex C to the
proxy statement/prospectus which is part of this registration statement on Form
S-4.

ITEM 22.   UNDERTAKINGS

     (a) The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
     a post-effective amendment to this registration statement:

               (i) To include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933.

               (ii) To reflect in the prospectus any facts or events arising
         after the effective date of the registration statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the registration statement. Notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar amount of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than a 20 percent change
         in the maximum aggregate offering price set forth in the "Calculation
         of Registration Fee" table in the effective registration statement.

               (iii) To include any material information with respect to the
         plan of distribution not previously disclosed in the registration
         statement or any material change to such information in the
         registration statement.

         (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

                                      II-2
<PAGE>   150

         (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c) The undersigned registrant hereby undertakes as follows:

         (1) That prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which is a part of this registration
     statement, by any person or party who is deemed to be an underwriter within
     the meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.

         (2) The registrant undertakes that every prospectus (i) that is filed
     pursuant to paragraph (c)(1) immediately preceding, or (ii) that purports
     to meet the requirements of Section 10(a)(3) of the Securities Act of 1933
     and is used in connection with an offering of securities subject to Rule
     415, will be filed as a part of an amendment to the registration statement
     and will not be used until such amendment is effective, and that, for
     purposes of determining any liability under the Securities Act of 1933,
     each such post-effective amendment shall be deemed to be a new registration
     statement relating to the securities offered therein, and the offering of
     such securities at that time shall be deemed to be the initial bona fide
     offering thereof.

     (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 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 such director, officer or controlling person in
connection with the securities being registered, 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 of 1933 and will be governed by the final adjudication of such issue.

                                      II-3
<PAGE>   151

     (e) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this registration statement through
the date of responding to the request.

     (f) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

Ortel Corporation
2015 West Chestnut Street
Alhambra, California 91803

          Re:  Agreement and Plan of Merger dated as of February 7, 2000, by and
               among Lucent Technologies Inc., Solara Acquisition Inc. and Ortel
               Corporation

Ladies and Gentlemen:

     We have acted as special counsel to Ortel Corporation, a Delaware
corporation (the "Company"), in connection with the proposed merger (the
"Merger") of Solara Acquisition Inc., a Delaware corporation ("Acquisition")
and wholly owned subsidiary of Lucent Technologies Inc., a Delaware corporation
("Lucent"), with and into the Company. All capitalized terms used but not
defined herein have the meanings ascribed to them in the Agreement and Plan of
Merger, dated as of February 7, 2000, among Lucent, Acquisition and the Company
(the "Merger Agreement").

     In that connection, pursuant to Section 6.3(b) of the Merger Agreement,
you have requested our opinion regarding whether the Merger will be treated as
a reorganization under Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"). In rendering our opinion, we have assumed with your
consent that (i) the representations made by Lucent, Acquisition and the
Company in letters provided to us and Sidley & Austin, counsel to Lucent, dated
as of the date hereof are true, correct and complete, and will be true, correct
and complete as of the Effective Time (as if made as of the Effective Time),
and (ii) any representations made
<PAGE>   2

LATHAM & WATKINS

in such letters "to the best knowledge of" or similarly qualified are true,
correct and complete without such qualification. We have also examined and are
relying upon (without any independent investigation or review thereof) the truth
and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in (i) the Merger Agreement, (ii) the
registration statement on Form S-4 which includes the Proxy Statement/Prospectus
(the "Registration Statement") filed by Lucent with the Securities and Exchange
Commission (the "SEC"), and (iii) such other documents and corporate records as
we have deemed necessary or appropriate for purposes of our opinion.

     In addition, we have assumed that:

     1. Original documents (including signatures) are authentic, documents
     submitted to us as copies conform to the original documents, and there has
     been due execution and delivery of all documents where due execution and
     delivery are prerequisites to the effectiveness thereof;

     2. The Merger will be consummated in the manner contemplated by the
     Registration Statement and in accordance with the provisions of the Merger
     Agreement, and will be effective under the laws of the State of Delaware;

     3. All statements, descriptions and representations contained in any of the
     documents referred to herein or otherwise made to us are true and correct
     in all material respects, and no actions have been taken or will be taken
     which are inconsistent with such statements, descriptions or
     representations or which make any such statements, descriptions or
     representations untrue or incorrect in any material respect; and

     4. Any statements made in any of the documents referred to herein "to the
     knowledge of" or similarly qualified are correct and will continue to be
     true, correct and complete at all times up to and including the Closing
     Date, in each case without such qualification.

     If any of the above-described assumptions is untrue for any reason or if
the Merger is consummated in a manner that is inconsistent with the manner in
which it is described in the Merger Agreement and Registration Statement, our
opinion as expressed below may be adversely affected and may not be relied upon.

     Based upon the foregoing, and subject to the qualifications and limitations
stated herein, we are of the opinion that for federal income tax purposes the
Merger will be treated as a reorganization within the meaning of Section 368(a)
of the Code.

     In addition to the matters set forth above, this opinion is subject to the
exceptions, limitations and qualifications set forth below:

          1. This opinion represents and is based upon our best judgment
regarding the application of United States Federal income tax laws arising
under the Code, judicial decisions, administrative regulations and published
rulings and procedures. Our opinion is not binding upon the Internal Revenue
Service or the courts, and there is no assurance that the Internal Revenue
Service will not assert a contrary position. Furthermore, no assurance can be
given that future legislative, judicial or administrative changes, on either a
prospective or retroactive basis, would not adversely affect the accuracy of
the conclusions stated herein. Nevertheless, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the
United States federal income tax laws.

          2. This opinion addresses only the matters set forth above and,
except as stated above, does not address any other United States federal,
state, local or foreign tax consequences that may result from the Merger or any
other transaction. In addition, we express no opinion as to any transaction
other than the Merger as described in the Merger Agreement or to any
transaction whatsoever, including the Merger, if, to the extent relevant to our
opinion, either all the transactions described in the Merger Agreement are not
consummated in accordance with the terms of the Merger Agreement and without
waiver or breach of any provisions thereof or all of the representations,
warranties, statements and assumptions upon which we have relied are not true
and accurate at all relevant times. In the event that any one of the
statements, representations, warranties or assumptions upon which we have
relied to issue this opinion is incorrect, our opinion might be adversely
affected and may not be relied upon.

          3. This opinion has been delivered to you for your use in connection
with the filing of the Registration Statement with the SEC and for the purpose
of satisfying the requirement set forth in Section 6.3(b) of the Merger
Agreement. It is not to be used, circulated, quoted or otherwise referred to
for any other purpose without our express written permission. In addition, this
opinion letter may not be relied upon by or furnished to any other person,
firm, corporation or entity without our prior written consent.

                                        Very truly yours,
