Item 5.   Other Events

On June 2, 1998, Tellabs, Inc., a Delaware corporation ("Tellabs"),
White Oak Merger Corp., a Delaware corporation and a wholly-owned
subsidiary of Tellabs ("Sub"), and CIENA Corporation, a Delaware
corporation ("CIENA"), entered into an Agreement and Plan of Merger
(the "Merger Agreement"), providing for the merger of the Sub with and
into CIENA (the "Merger"), with CIENA surviving the Merger and becoming
a wholly-owned subsidiary of Tellabs.  Pursuant to the Merger Agreement,
by virtue of the Merger each outstanding share of common stock, $.01 par
value per share, of CIENA will be converted into the right to receive
one share of common stock, $.01 par value per share, of Tellabs. 

In connection with the Merger Agreement, CIENA and Tellabs entered into
a Stock Option Agreement, also dated as of June 2, 1998 (the "Stock
Option Agreement") pursuant to which CIENA granted Tellabs an option to
purchase up to 19.9% of CIENA's common stock upon the occurrence of
certain events, including the acquisition of 20% or more of CIENA's
stock by any other party.

The transaction is expected to qualify as a tax-free reorganization
and to be treated as a pooling of interests for accounting purposes.
Consummation of the Merger is subject to a number of conditions
including approval by the stockholders of CIENA and Tellabs, and the
receipt of all necessary regulatory approvals.

Further details regarding the Merger are contained in the copies of
the Merger Agreement, the Stock Option Agreement and the joint press
release issued by Tellabs and CIENA on June 3, 1998, attached hereto as
Exhibits 2.2, 2.3 and 99.2, respectively.  All of these exhibits are
incorporated by reference herein.

                    AGREEMENT AND PLAN OF MERGER


          AGREEMENT AND PLAN OF MERGER, dated as of June 2, 1998 (this
"Agreement"), among Tellabs, Inc., a Delaware corporation ("Parent"),
White Oak Merger Corp., a Delaware corporation and a direct wholly owned
subsidiary of Parent ("Sub"), and CIENA Corporation, a Delaware
corporation (the "Company") (Sub and the Company being hereinafter
collectively referred to as the "Constituent Corporations").


                         W I T N E S S E T H:


          WHEREAS, the respective Boards of Directors of Parent, Sub and
the Company have approved and declared advisable the merger of Sub with
and into the Company (the "Merger"), upon the terms and subject to the
conditions set forth herein, whereby each issued and outstanding share
of common stock, par value $.01 per share, of the Company ("Company
Common Stock") not owned directly or indirectly by Parent or the Company
will be converted into shares of Common Stock, par value $.01 per share,
of Parent ("Parent Common Stock");

          WHEREAS, the respective Boards of Directors of Parent and the
Company have determined that the Merger is in furtherance of and
consistent with their respective long-term business strategies and is in
the best interest of their respective stockholders;

          WHEREAS, in order to induce Parent and Sub to enter into this
Agreement, concurrently herewith Parent and the Company are entering
into the Stock Option Agreement dated as of the date hereof (the "Stock
Option Agreement") in the form of the attached Exhibit A;

          WHEREAS, in order to induce Parent and Sub to enter into this
Agreement, concurrently herewith certain stockholders and each of the
directors of the Company are entering into stockholder agreements with
Parent (the "Stockholder Agreements"), pursuant to which, among other
things, each such stockholder and director (in such director's capacity
as a stockholder) agrees to vote in favor of this Agreement and the
Merger and against any competing proposals;

          WHEREAS, for federal income tax purposes, it is intended that
the Merger shall qualify as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code"); and

          WHEREAS, it is intended that the Merger shall be recorded for
accounting purposes as a pooling of interests.

          NOW, THEREFORE, in consideration of the premises,
representations, warranties and agreements herein contained, the  
parties agree as follows:

                






                              ARTICLE I


                             THE MERGER

          Section 1.1    The Merger.  Upon the terms and subject  
to the conditions hereof, and in accordance with the Delaware General
Corporation Law (the "DGCL"), Sub shall be merged with and into the
Company at the Effective Time (as hereinafter defined).  Following the
Merger, the separate corporate existence of Sub shall cease and the
Company shall continue as the surviving corporation (the "Surviving
Corporation") and shall succeed to and assume all the rights and
obligations of Sub in accordance with the DGCL. Notwithstanding anything
to the contrary herein, at the election of Parent, any direct wholly
owned Subsidiary (as hereinafter defined) of Parent may be substituted
for Sub as a constituent corporation in the Merger; provided that such
substituted corporation is a Delaware corporation which is formed solely
for the purpose of engaging in the transactions contemplated by this
Agreement and has engaged in no other business activities.  In such
event, the parties agree to execute an appropriate amendment to this
Agreement, in form and substance reasonably satisfactory to Parent and
the Company, in order to reflect such substitution.

          Section 1.2    Effective Time.  The Merger shall become
effective when a Certificate of Merger (the "Certificate of Merger"),
executed in accordance with the relevant provisions of the DGCL, is
filed with the Secretary of State of the State of Delaware; provided,
however, that, upon mutual consent of the Constituent Corporations, the
Certificate of Merger may provide for a later date of effectiveness of
the Merger not more than 30 days after the date the Certificate of
Merger is filed.  When used in this Agreement, the term "Effective Time"
shall mean the date and time at which the Certificate of Merger is
accepted for recording or such later time established by the Certificate
of Merger.  The filing of the Certificate of Merger shall be made on the
date of the Closing (as hereinafter defined).

          Section 1.3    Effects of the Merger; Directors and Officers.
The Merger shall have the effects set forth in this Agreement and in
Section 259 of the DGCL.

          Section 1.4    Charter and Bylaws; Directors and Officers.
(a) At the Effective Time, the Third Restated Certificate of
Incorporation, as amended, of the Company (the "Company Charter"), as in
effect immediately prior to the Effective Time, shall be amended so that
(i) Article FOURTH of the Company Charter reads in its entirety as
follows: "The total number of shares of all classes of capital stock
which the Corporation shall have authority to issue is 1,000 shares of
Common Stock, par value $.01 per share".  As so amended, the Company
Charter shall be the Certificate of Incorporation of the Surviving
Corporation until thereafter changed or amended as provided therein or
by applicable law.  At the Effective Time, the Amended and Restated
laws of the Company (the "Company Bylaws"), as in effect immediately
 
 






prior to the Effective Time, shall be the Bylaws of the Surviving
Corporation until thereafter changed or amended as provided therein or
by the Company Charter.

          (b)  The directors of Sub at the Effective Time of the  
Merger shall be the directors of the Surviving Corporation, until the
earlier of their resignation or removal or until their respective
successors are duly elected and qualified, as the case may be.  The
officers of the Company at the Effective Time of the Merger shall be the
officers of the Surviving Corporation, until the earlier of their
resignation or removal or until their respective successors are duly
elected and qualified, as the case may be.

          Section 1.5    Conversion of Securities.  As of the Effective
Time, by virtue of the Merger and without any action on the part of Sub,
the Company or the holders of any securities of the Constituent
Corporations:

          (a)  Each issued and outstanding share of common stock, par
value $.01 per share, of Sub shall be converted into one validly issued,
fully paid and nonassessable share of common stock of the Surviving
Corporation.

          (b) All shares of Company Common Stock, together with
associated Rights (as hereinafter defined), that are held in the
treasury of the Company or by any wholly owned Subsidiary of the Company
and any shares of Company Common Stock, together with the associated
Rights, owned by Parent shall be cancelled and no capital stock of
Parent or other consideration shall be delivered in exchange therefor.

          (c) Subject to the provisions of Sections 1.8 and 1.10 hereof,
each share of Company Common Stock issued and outstanding immediately
prior to the Effective Time (other than shares to be cancelled in
accordance with Section 1.5(b)), together with the associated Rights,
shall be converted into one (such number being the "Exchange Ratio")
validly issued, fully paid and nonassessable share of Parent Common
Stock.  All such shares of Company Common Stock and the associated
Rights, when so converted, shall no longer be outstanding and shall
automatically be cancelled and retired and each holder of a certificate
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive any dividends and other
distributions in accordance with Section 1.7, certificates representing
the shares of Parent Common Stock into which such shares are converted
and any cash, without interest, in lieu of fractional shares to be
issued or paid in consideration therefor upon the surrender of such
certificate in accordance with Section 1.6.

          Section 1.6    Parent to Make Certificates Available.  (a)
Exchange of Certificates.  Parent shall authorize a commercial bank (or
such other person or persons as shall be reasonably acceptable to Parent
and the Company) to act as Exchange Agent hereunder (the "Exchange
Agent").  As soon as practicable after the Effective Time, Parent shall
deposit with the Exchange Agent certificates representing the shares of
Parent Common Stock issuable pursuant to Section 1.5(c) for exchange






with outstanding shares of Company Common Stock and cash, as required to
make payments in lieu of any fractional shares pursuant to Section 1.8
(such cash and shares of Parent Common Stock, together with any
dividends or distributions with respect thereto, being hereinafter
referred to as the "Exchange Fund").  The Exchange Agent shall deliver
the Parent Common Stock contemplated to be issued pursuant to Section
1.5(c) out of the Exchange Fund.

          (b)  Exchange Procedures.  Parent shall instruct the Exchange
Agent, as soon as practicable after the Effective Time, to mail to each
record holder of a certificate or certificates which immediately prior
to the Effective Time represented outstanding shares of Company Common
Stock converted in the Merger (the "Certificates") a letter of
transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon actual
delivery of the Certificates to the Exchange Agent, and shall contain
instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of Parent Common Stock and
cash in lieu of fractional shares).  Upon surrender for cancellation to
the Exchange Agent of all Certificates held by any record holder of a
Certificate, together with such letter of transmittal, duly executed,
the holder of such Certificate shall be entitled to receive in exchange
therefor a certificate representing that number of whole shares of
Parent Common Stock into which the shares represented by the surrendered
Certificate shall have been converted at the Effective Time pursuant to
this Article I, cash in lieu of any fractional share in accordance with
Section 1.8 and certain dividends and other distributions in accordance
with Section 1.7, and any Certificate so surrendered shall forthwith be
cancelled.

          Section 1.7    Dividends; Transfer Taxes; Withholding.  No
dividends or other distributions that are declared on or after the
Effective Time on Parent Common Stock, or are payable to the holders of
record thereof on or after the Effective Time, will be paid to any
person entitled by reason of the Merger to receive a certificate
representing Parent Common Stock until such person surrenders the
related Certificate or Certificates, as provided in Section 1.6, and no
cash payment in lieu of fractional shares will be paid to any such
person pursuant to Section 1.8 until such person shall so surrender the
related Certificate or Certificates.  Subject to the effect of
applicable law, there shall be paid to each record holder of a new
certificate representing such Parent Common Stock: (i) at the time of
such surrender or as promptly as practicable thereafter, the amount of
any dividends or other distributions theretofore paid with respect to
the shares of Parent Common Stock represented by such new certificate
and having a record date on or after the Effective Time and a payment
date prior to such surrender; (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 Parent Common Stock
and having a record date on or after the Effective Time but prior to
such surrender and a payment date on or subsequent to such surrender;
and (iii) at the time of such surrender or as promptly as practicable
thereafter, the amount of any cash payable with respect to a fractional
share of Parent Common Stock to which such holder is entitled pursuant






to Section 1.8.  In no event shall the person entitled to receive such
dividends or other distributions or cash in lieu of fractional shares be
entitled to receive interest on such dividends or other distributions or
cash in lieu of fractional shares.  If any cash or certificate
representing shares of Parent Common Stock is to be paid to or issued in
a name other than that in which the Certificate surrendered in exchange
therefor is registered, it shall be a condition of such exchange that
the Certificate so surrendered shall be properly endorsed and otherwise
in proper form for transfer and that the person requesting such exchange
shall pay to the Exchange Agent any transfer or other taxes required by
reason of the issuance of certificates for such shares of Parent Common
Stock in a name other than that of the registered holder of the
Certificate surrendered, or shall establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not applicable.  Parent
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 Parent or the Exchange
Agent is required to deduct and withhold with respect to the making of
such payment under the Code or under any provision of state, local or
foreign tax law.  To the extent that amounts are so withheld by Parent
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 Parent or the Exchange Agent.

          Section 1.8    No Fractional Securities.  No certificates  
or scrip representing fractional shares of Parent Common Stock shall be
issued upon the surrender for exchange of Certificates pursuant to this
Article I, and no Parent dividend or other distribution or stock split
shall relate to any fractional share, and no fractional share shall
entitle the owner thereof to vote or to any other rights of a security
holder of Parent.  In lieu of any such fractional share, each holder of
Company Common Stock who would otherwise have been entitled to a
fraction of a share of Parent Common Stock upon surrender of
Certificates for exchange pursuant to this Article I will be paid an
amount in cash (without interest), rounded to the nearest cent,
determined by multiplying (i) the last reported sale price per share of
Parent Common Stock on The Nasdaq Stock Market ("NASDAQ") on the date of
the Effective Time (or, if the shares of Parent Common Stock do not
trade on NASDAQ on such date, the first date of trading of shares of
Parent Common Stock on NASDAQ after the Effective Time) by (ii) the
fractional interest to which such holder would otherwise be entitled.
As promptly as practicable after the determination of the amount of
cash, if any, to be paid to holders of fractional share interests, the
Exchange Agent shall so notify Parent, and Parent shall deposit such
amount with the Exchange Agent and shall cause the Exchange Agent to
forward payments to such holders of fractional share interests subject
to and in accordance with the terms of Section 1.7 and this Section 1.8.

          Section 1.9    Return of Exchange Fund.   Any portion of the
Exchange Fund which remains undistributed to the former stockholders of
the Company for six months after the Effective Time shall be delivered
to Parent, upon demand of Parent, and any such former stockholders who
have not theretofore complied with this Article I shall thereafter look






only to Parent for payment of their claim for Parent Common Stock, any
cash in lieu of fractional shares of Parent Common Stock and any
dividends or distributions with respect to Parent Common Stock.  Neither
Parent nor the Surviving Corporation shall be liable to any former
holder of Company Common Stock for any such shares of Parent Common
Stock, cash and dividends and distributions held in the Exchange Fund
which is delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

          Section 1.10   Adjustment of Exchange Ratio.  In the event of
any reclassification, stock split or stock dividend with respect to
Parent Common Stock or any change or conversion of Parent Common Stock
into other securities (or if a record date with respect to any of the
foregoing should occur) prior to the Effective Time, appropriate and
proportionate adjustments, if any, shall be made to the Exchange Ratio,
and all references to the Exchange Ratio in this Agreement shall be
deemed to be to the Exchange Ratio as so adjusted.

          Section 1.11   No Further Ownership Rights in Company Common
Stock.  All shares of Parent Common Stock issued upon the surrender for
exchange of Certificates in accordance with the terms hereof (including
any cash paid pursuant to Section 1.8) shall be deemed to have been
issued in full satisfaction of all rights pertaining to the shares of
Company Common Stock represented by such Certificates.

          Section 1.12   Closing of Company Transfer Books.  At the
Effective Time, the stock transfer books of the Company shall be closed
and no transfer of shares of Company Common Stock shall thereafter be
made on the records of the Company.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation, the Exchange
Agent or the Parent, such Certificates shall be cancelled and exchanged
as provided in this Article I.

          Section 1.13   Lost Certificates.  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, if required by Parent or the Exchange Agent, the posting
by such person of a bond, in such reasonable amount as Parent or the
Exchange Agent may direct as indemnity against any claim that may be
made against them with respect to such Certificate, the Exchange Agent
will issue in exchange for such lost, stolen or destroyed Certificate
the shares of Parent Common Stock, any cash in lieu of fractional shares
of Parent Common Stock to which the holders thereof are entitled
pursuant to Section 1.8 and any dividends or other distributions to
which the holders thereof are entitled pursuant to Section 1.7.

          Section 1.14   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 of the Constituent
Corporations, 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 of the Constituent Corporations, all
such deeds, bills of sale, assignments and assurances and to do, in the
name and on behalf of either Constituent Corporation, all such other
acts and things as may be necessary, desirable or proper to vest,
perfect or confirm the Surviving Corporation's right, title or interest
in, to or under any of the rights, privileges, powers, franchises,
properties or assets of such Constituent Corporation and otherwise to
carry out the purposes of this Agreement.

          Section 1.15   Closing.  The closing of the transactions
contemplated by this Agreement (the "Closing") and all actions specified
in this Agreement to occur at the Closing shall take place at the
offices of Sidley & Austin, One First National Plaza, Chicago, Illinois,
at 10:00 a.m., local time, no later than the second business day
following the day on which the last of the conditions set forth in
Article VI shall have been fulfilled or waived (if permissible) or at
such other time and place as Parent and the Company shall agree.


                              ARTICLE II

            REPRESENTATIONS AND WARRANTIES OF PARENT AND SUB

          Parent and Sub represent and warrant to the Company as
follows:

          Section 2.1    Organization, Standing and Power.  Each of
Parent and Sub is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware and has the
requisite corporate power and authority to carry on its business as now
being conducted.  Each Subsidiary (as hereinafter defined) of Parent is
duly organized, validly existing and in good standing under the laws of
the jurisdiction in which it is organized and has the requisite
corporate (in the case of a Subsidiary that is a corporation) or other
power and authority to carry on its business as now being conducted,
except where the failure to be so organized, existing or in good
standing or to have such power or authority would not, individually or
in the aggregate, have a Material Adverse Effect (as hereinafter
defined) on Parent.  Parent and each of its Subsidiaries are duly
qualified to do business, and are in good standing, in each jurisdiction
where the character of their properties owned or held under lease or the
nature of their activities makes such qualification necessary, except
where the failure to be so qualified would not, individually or in the
aggregate, have a Material Adverse Effect on Parent.  For purposes of
this Agreement (a) "Material Adverse Change" or "Material Adverse
Effect" means, when used with respect to Parent or the Company, as the
case may be, any event, change or effect that individually or when taken
together with all other such events, changes or effects is or could
reasonably be expected (as far as can be foreseen at the time) to be
materially adverse to the business, assets, liabilities, financial
condition or results of operations of Parent and its Subsidiaries, taken
as a whole, or the Company and its Subsidiaries, taken as a whole, as






the case may be; provided, however, that in determining whether a
Material Adverse Change or Material Adverse Effect has occurred with
respect to either referenced party, any change or effect, to the extent
it is attributable (i) to any change in general economic conditions
affecting companies in industries similar to the industries in which the
Company and its Subsidiaries or Parent and its Subsidiaries, as the case
may be, operate or (ii) to the closing or the failure to close the
merger contemplated in that certain Agreement of Plan of Merger dated as
of February 16, 1998 among Parent, Cardinal Merger Co. and Coherent
Communications Systems Corporation substantially on the terms set forth
therein (so long as such closing or failure to close does not result in
any material liability to Parent), shall not be considered when
determining if a Material Adverse Change or Material Adverse Effect has
occurred; and (b) "Subsidiary" means any corporation, partnership,
limited liability company, joint venture or other legal entity of which
Parent or the Company, as the case may be (either alone or through or
together with any other Subsidiary), owns, directly or indirectly, 50%
or more of the stock or other equity interests the holders of which are
generally entitled to vote for the election of the board of directors or
other governing body of such corporation, partnership, limited liability
company, joint venture or other legal entity.

          Section 2.2    Capital Structure.  (a) As of the date hereof,
the authorized capital stock of Parent consists of 500,000,000 shares of
Parent Common Stock and 5,000,000 shares of Preferred Stock, par value
$.01 per share (the "Parent Preferred Stock").  At the close of business
on May 28, 1998, (i) 182,425,765 shares of Parent Common Stock were
issued and outstanding, all of which were validly issued, fully paid and
nonassessable and free of preemptive rights, (ii) no shares of Parent
Common Stock were held in treasury of Parent or by Subsidiaries of
Parent, (iii) no shares of Parent Preferred Stock were issued or
outstanding, (iv) 10,194,606 shares of Parent Common Stock were reserved
for issuance pursuant to outstanding options or other rights to purchase
or otherwise acquire shares of Parent Common Stock under Parent's
benefit plans or arrangements or pursuant to any plans assumed by Parent
in connection with any acquisition, business combination or similar
transaction (collectively, the "Parent Stock Plans"), (v) 149,370 stock
appreciation rights granted pursuant to the Parent Stock Plans and (vi)
11,772,949 shares of Parent Common Stock were reserved for issuance in
connection with that certain Agreement and Plan of Merger dated as of
February 16, 1998 among Parent, Cardinal Merger Co. and Coherent
Communications Systems Corporation.  As of the date of this Agreement,
except as set forth above and except for the issuance of shares of
Parent Common Stock pursuant to the Parent Stock Plans, no shares of
capital stock or other voting securities of Parent were issued, reserved
for issuance or outstanding.  All of the shares of Parent Common Stock
issuable in exchange for Company Common Stock at the Effective Time in
accordance with this Agreement will be, when so issued, duly authorized,
validly issued, fully paid and nonassessable and free of preemptive
rights.  As of the date of this Agreement, except for (i) this Agreement
and (ii) as set forth above, there are no options, warrants, calls,
rights, puts or agreements to which Parent or any of its Subsidiaries is
a party or by which any of them is bound obligating Parent or any of its
Subsidiaries to issue, deliver, sell or redeem, or cause to be issued,






delivered, sold or redeemed, any additional shares of capital stock (or
other voting securities or equity equivalents) of Parent or any of its
Subsidiaries or obligating Parent or any of its Subsidiaries to grant,
extend or enter into any such option, warrant, call, right, put or
agreement.

          (b)  As of the date of this Agreement, each outstanding share
of capital stock (or other voting security or equity equivalent) of each
material Subsidiary of Parent is duly authorized, validly issued, fully
paid and nonassessable and, except for director or qualifying shares,
each such share (or other voting security or equity equivalent) is owned
by Parent or another Subsidiary of Parent, free and clear of all
security interests, liens, claims, pledges, options, rights of first
refusal, agreements, limitations on voting rights, charges and other
encumbrances of any nature whatsoever.  Except as set forth above,
Parent does not have any outstanding bonds, debentures, notes or other
obligations the holders of which have the right to vote (or convertible
into or exercisable for securities having the right to vote) with the
stockholders of Parent on any matter.  Exhibit 21 to Parent's Annual
Report on Form 10-K for the year ended January 2, 1998, as filed with
the Securities and Exchange Commission (the "SEC") (the "Parent Annual
Report"), is a true, accurate and correct statement in all material
respects of all of the information required to be set forth therein by
the regulations of the SEC.

          (c)  Section 2.2 of the letter dated the date hereof and
delivered on the date hereof by Parent to the Company, which letter
relates to this Agreement and is designated the Parent Letter (the
"Parent Letter"), sets forth a list as of the date hereof of all
Subsidiaries and Joint Ventures (as defined below) of Parent and the
jurisdiction in which such Subsidiary or Joint Venture is organized.
Section 2.2 of the Parent Letter also sets forth as of the date hereof
the nature and extent of the ownership and voting interests held by
Parent in each such Joint Venture.  As of the date hereof, Parent has no
obligation to make any capital contributions, or otherwise provide
assets or cash, to any Joint Venture.  As used in this Agreement, "Joint
Venture" means, with respect to a party, any corporation, limited
liability company, partnership, joint venture or other entity which is
not a Subsidiary of such party and in which (i) such party, directly or
indirectly, owns or controls any shares of any class of the outstanding
voting securities or other equity interests (other than the ownership of
securities primarily for investment purposes as part of routine cash
management or investments of 1% or less in publicly traded companies),
or (ii) such party or a Subsidiary of such party is a general partner.

          Section 2.3    Authority.  On or prior to the date of this
Agreement, the Boards of Directors of Parent and Sub have declared the
Merger advisable and fair to and in the best interest of Parent and Sub,
respectively, and their respective stockholders, approved and adopted
this Agreement in accordance with the DGCL, and the Board of Directors
of Parent has resolved to recommend the approval by Parent's
stockholders of the issuance of Parent Common Stock in connection with
the Merger (the "Share Issuance").  Each of Parent and Sub has all
requisite corporate power and authority to enter into this Agreement,






Parent has all requisite corporate power and authority to enter into the
Stock Option Agreement, and, subject to approval by the stockholders of
Parent of the Share Issuance, to consummate the transactions
contemplated hereby and thereby.  The execution and delivery of this
Agreement by Parent and Sub, the execution and delivery of the Stock
Option Agreement by Parent and the consummation by Parent and Sub of the
transactions contemplated hereby and thereby have been duly authorized
by all necessary corporate action on the part of Parent and Sub, subject
to (x) approval by the stockholders of Parent of the Share Issuance and
(y) the filing of appropriate Merger documents as required by the DGCL.
This Agreement and the consummation of the transactions contemplated
hereby have been approved by the sole stockholder of Sub.  This
Agreement has been duly executed and delivered by Parent and Sub, the
Stock Option Agreement has been duly executed and delivered by Parent,
and (assuming the valid authorization, execution and delivery of this
Agreement and the Stock Option Agreement by the Company and the validity
and binding effect hereof and thereof on the Company) this Agreement
constitutes the valid and binding obligation of Parent and Sub
enforceable against each of them in accordance with its terms and the
Stock Option Agreement constitutes the valid and binding obligation of
Parent enforceable against Parent in accordance with its terms.  The
Share Issuance and the filing of a registration statement on Form S-4
with the SEC by Parent under the Securities Act of 1933, as amended
(together with the rules and regulations promulgated thereunder, the
"Securities Act"), for the purpose of registering the shares of Parent
Common Stock to be issued in the Merger (together with any amendments or
supplements thereto, whether prior to or after the effective date
thereof, the "Registration Statement") have been duly authorized by
Parent's Board of Directors.

          Section 2.4    Consents and Approvals; No Violation.  Assuming
that all consents, approvals, authorizations and other actions described
in this Section 2.4 have been obtained and all filings and obligations
described in this Section 2.4 have been made, and except as set forth in
Section 2.4 of the Parent Letter, the execution and delivery of this
Agreement and the Stock Option Agreement do not, and the consummation of
the transactions contemplated hereby and thereby and compliance with the
provisions hereof and thereof will not, result in any violation of, or
default (with or without notice or lapse of time, or both) under, or
give to others a right of termination, cancellation or acceleration of
any obligation or the loss of a material benefit under, or result in the
creation of any lien, security interest, charge or encumbrance upon any
of the properties or assets of Parent or any of its Subsidiaries under,
any provision of (i) the Restated Certificate of Incorporation, as
amended, of Parent (the "Parent Charter") or the Amended and Restated
By-laws of Parent (the "Parent Bylaws") or the Certificate of
Incorporation or Bylaws of Sub, (ii) any provision of the comparable
charter or organization documents of any of Parent's Subsidiaries, (iii)
any loan or credit agreement, note, bond, mortgage, indenture, lease or
other agreement, instrument, permit, concession, franchise or license
applicable to Parent or any of its Subsidiaries or (iv) any judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to
Parent or any of its Subsidiaries or any of their respective properties
or assets, other than, in the case of clauses (ii), (iii) or (iv), any






such violations, defaults, rights, liens, security interests, charges or
encumbrances that, individually or in the aggregate, would not have a
Material Adverse Effect on Parent, materially impair the ability of
Parent or Sub to perform their respective obligations hereunder or under
the Stock Option Agreement or prevent the consummation of any of the
transactions contemplated hereby or thereby.  No filing or registration
with, or authorization, consent or approval of, any domestic (federal
and state), foreign or supranational court, commission, governmental
body, regulatory agency, authority or tribunal (a "Governmental Entity")
is required by or with respect to Parent or any of its Subsidiaries in
connection with the execution and delivery of this Agreement or the
Stock Option Agreement by Parent or Sub or is necessary for the
consummation of the Merger and the other transactions contemplated by
this Agreement or the Stock Option Agreement, except for (i) in
connection, or in compliance, with the provisions of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
"HSR Act"), the Securities Act and the Securities Exchange Act of 1934,
as amended (together with the rules and regulations promulgated
thereunder, the "Exchange Act"), (ii) the filing of the Certificate of
Merger with the Secretary of State of the State of Delaware and
appropriate documents with the relevant authorities of other states in
which the Company or any of its Subsidiaries is qualified to do
business, (iii) such filings, authorizations, orders and approvals as
may be required by state takeover laws (the "State Takeover Approvals"),
(iv) such filings as may be required in connection with the taxes
described in Section 5.11, (v) applicable requirements, if any, of state
securities or "blue sky" laws ("Blue Sky Laws") and NASDAQ, (vi) as may
be required under foreign laws and (vii) such other consents, orders,
authorizations, registrations, declarations and filings the failure of
which to be obtained or made would not, individually or in the
aggregate, have a Material Adverse Effect on Parent, materially impair
the ability of Parent or Sub to perform its obligations hereunder or
under the Stock Option Agreement or prevent the consummation of any of
the transactions contemplated hereby or thereby.

          Section 2.5    SEC Documents and Other Reports.  Parent has
timely filed all required documents with the SEC since January 1, 1997
(the "Parent SEC Documents").  As of their respective dates, the Parent
SEC Documents complied in all material respects with the requirements of
the Securities Act or the Exchange Act, as the case may be, and, at the
respective times they were filed, none of the Parent SEC Documents
contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were
made, not misleading.  The consolidated financial statements (including,
in each case, any notes thereto) of Parent included in the Parent SEC
Documents complied as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the
SEC with respect thereto, were prepared in accordance with generally
accepted accounting principles (except, in the case of the unaudited
statements, as permitted by Form 10-Q of the SEC) applied on a
consistent basis during the periods involved (except as may be indicated
therein or in the notes thereto) and fairly presented in all material
respects the consolidated financial position of Parent and its






consolidated Subsidiaries as at the respective dates thereof and the
consolidated results of their operations and their consolidated cash
flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments and to any other
adjustments described therein).  Except as disclosed in the Parent SEC
Documents or as required by generally accepted accounting principles,
Parent has not, since January 2, 1998, made any change in the accounting
practices or policies applied in the preparation of financial
statements.

          Section 2.6    Registration Statement and Joint Proxy
Statement.  None of the information to be supplied by Parent or Sub for
inclusion or incorporation by reference in the Registration Statement or
the joint proxy statement/prospectus included therein relating to the
Stockholder Meetings (as defined in Section 5.1) (together with any
amendments or supplements thereto, the "Joint Proxy Statement") will (i)
in the case of the Registration Statement, at the time it becomes
effective, 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 not misleading or (ii) in the case
of the Joint Proxy Statement, at the time of the mailing of the Joint
Proxy Statement, at the time of each of the Stockholder Meetings and at
the Effective Time, 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.  If at any time
prior to the Effective Time any event with respect to Parent, its
officers and directors or any of its Subsidiaries shall occur which is
required to be described in the Joint Proxy Statement or the
Registration Statement, such event shall be so described, and an
appropriate amendment or supplement shall be promptly filed with the SEC
and, as required by law, disseminated to the stockholders of Parent and
the Company.  The Registration Statement will comply (with respect to
Parent) as to form in all material respects with the provisions of the
Securities Act, and the Joint Proxy Statement will comply (with respect
to Parent) as to form in all material respects with the provisions of
the Exchange Act.

          Section 2.7    Absence of Certain Changes or Events.  Except
as disclosed in Parent SEC Documents filed with the SEC prior to the
date of this Agreement or as disclosed in Section 2.7 of the Parent
Letter, since January 2, 1998 (A) Parent and its Subsidiaries have not
incurred any liability or obligation (indirect, direct or contingent)
that would result in a Material Adverse Effect on Parent or, through the
date hereof, entered into any material oral or written agreement or
other transaction that is not in the ordinary course of business or that
would result in a Material Adverse Effect on Parent, (B) Parent and its
Subsidiaries have not sustained any loss or interference with their
business or properties from fire, flood, windstorm, accident or other
calamity (whether or not covered by insurance) that has had a Material
Adverse Effect on Parent, (C) through the date hereof, there has been no
change in the capital stock of Parent except for the issuance of shares
of Parent Common Stock pursuant to Parent Stock Plans and no dividend or
distribution of any kind declared, paid or made by Parent on any class






of its stock, and (D) there has been no event causing a Material Adverse
Effect on Parent, nor any development that would, individually or in the
aggregate, result in a Material Adverse Effect on Parent.

          Section 2.8    Permits and Compliance.  (a) Each of Parent  
and its Subsidiaries is in possession of all franchises, grants,
authorizations, licenses, permits, charters, easements, variances,
exceptions, consents, certificates, approvals and orders of any
Governmental Entity necessary for Parent or any of its Subsidiaries to
own, lease and operate its properties or to carry on its business as it
is now being conducted (the "Parent Permits"), except where the failure
to have any of the Parent Permits would not, individually or in the
aggregate, have a Material Adverse Effect on Parent, and, as of the date
of this Agreement, no suspension or cancellation of any of the Parent
Permits is pending or, to the Knowledge of Parent (as hereinafter
defined), threatened, except where the suspension or cancellation of any
of the Parent Permits would not, individually or in the aggregate, have
a Material Adverse Effect on Parent.  Neither Parent nor any of its
Subsidiaries is in violation of (A) its charter, by-laws or other
organizational documents, (B) any applicable law, ordinance,
administrative or governmental rule or regulation or (C) any order,
decree or judgment of any Governmental Entity having jurisdiction over
Parent or any of its Subsidiaries, except, in the case of clauses (A),
(B) and (C), for any violations that, individually or in the aggregate,
would not have a Material Adverse Effect on Parent.

          (b)  Except as disclosed in the Parent SEC Documents filed
prior to the date of this Agreement or as disclosed in Section 2.8 of
the Parent Letter, as of the date hereof there is no contract or
agreement that is or was required to be filed by Parent as a material
contract pursuant to Item 601 of Regulation S-K under the Securities
Act.  Except as set forth in Section 2.8 of the Parent Letter, as of the
date hereof neither Parent nor any or its Subsidiaries is a party to or
bound by any agreements evidencing, or guarantees relating to,
indebtedness for borrowed money to the extent the aggregate principal
amount outstanding thereunder exceeds $10,000,000.  Except as set forth
in the Parent SEC Documents filed prior to the date of this Agreement or

                              ARTICLE III

               REPRESENTATIONS AND WARRANTIES OF THE COMPANY


          The Company represents and warrants to Parent and Sub as
follows:

          Section 3.1    Organization, Standing and Power.  The Company
is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware and has the requisite corporate
power and authority to carry on its business as now being conducted.
Each Subsidiary of the Company is duly organized, validly existing and
in good standing under the laws of the jurisdiction in which it is
organized and has the requisite corporate (in the case of a Subsidiary
that is a corporation) or other power and authority to carry on its
business as now being conducted, except where the failure to be so
organized, existing or in good standing or to have such power or
authority would not, individually or in the aggregate, have a Material
Adverse Effect on the Company.  The Company and each of its Subsidiaries
are duly qualified to do business, and are in good standing, in each
jurisdiction where the character of their properties owned or held under
lease or the nature of their activities makes such qualification
necessary, except where the failure to be so qualified would not,
individually or in the aggregate, have a Material Adverse Effect on the
Company.

          Section 3.2    Capital Structure.  (a) As of the date hereof,
the authorized capital stock of the Company consists of 360,000,000
shares of Company Common Stock and 20,000,000 shares of preferred stock,
par value $.01 per share ("Company Preferred Stock").  At the close of
business on May 28, 1998, (i) 101,628,989 shares of Company Common Stock
were issued and outstanding, all of which were validly issued, fully
paid and nonassessable and free of preemptive rights, (ii) no shares of
Company Common Stock were held in the treasury of the Company or by






Subsidiaries of the Company and (iii) 9,239,457 shares of Company Common
Stock were reserved for issuance pursuant to outstanding options (the
"Company Stock Options") to purchase shares of Company Common Stock
issued pursuant to the Company's Amended and Restated 1994 Stock Option
Plan and 1996 Outside Directors Stock Option Plan (collectively, the
"Company Stock Option Plans").  There are no shares issuable pursuant to
the Company's Employee Stock Purchase Plan (the "Company Stock Purchase
Plan").  The Company Stock Option Plans and the Company Stock Purchase
Plan are the only benefit plans of the Company or its Subsidiaries under
which any securities of the Company or any of its Subsidiaries are
issuable.  No shares of Company Preferred Stock are issued or
outstanding.  As of the date of this Agreement, except as set forth
above and except for the issuance of shares of Company Common Stock upon
the exercise of Company Stock Options outstanding on May 28, 1998 in
accordance with the terms thereof, no shares of capital stock or other
voting securities of the Company were issued, reserved for issuance or
outstanding.  As of the date of this Agreement, except for (i) as set
forth above, (ii) the Stock Option Agreement and (iii) rights to
purchase one-one-thousandth of a share of Series A Junior Participating
Preferred Stock (the "Rights") pursuant to a Rights Agreement dated as

BankBoston, N.A., as Rights Agent, there are no options, warrants,
calls, rights, puts or agreements to which the Company or any of its
Subsidiaries is a party or by which any of them is bound obligating the
Company or any of its Subsidiaries to issue, deliver, sell or redeem, or
cause to be issued, delivered, sold or redeemed, any additional shares
of capital stock (or other voting securities or equity equivalents) of
the Company or any of its Subsidiaries or obligating the Company or any
of its Subsidiaries to grant, extend or enter into any such option,
warrant, call, right, put or agreement.

          (b)  Each outstanding share of capital stock (or other voting
security or equity equivalent) of each material Subsidiary of the
Company is duly authorized, validly issued, fully paid and
nonassessable, and each such share (or other voting security or equity
equivalent) is owned by the Company or another Subsidiary of the
Company, free and clear of all security interests, liens, claims,
pledges, options, rights of first refusal, agreements, limitations on
voting rights, charges and other encumbrances of any nature whatsoever.
The Company does not have any outstanding bonds, debentures, notes or
other obligations the holders of which have the right to vote (or
convertible into or exercisable for securities having the right to vote)
with the stockholders of the Company on any matter.  Exhibit 21 to the
Company's Annual Report on Form 10-K for the year ended October 31,
1997, as filed with the SEC (the "Company Annual Report"), is a true,
accurate and correct statement in all material respects of all of the
information required to be set forth therein by the regulations of the
SEC.

          (c)  Section 3.2 of the letter dated the date hereof and
delivered on the date hereof by the Company to Parent, which letter
relates to this Agreement and is designated the Company Letter (the
"Company Letter"), sets forth a list of all Subsidiaries and Joint
Ventures of the Company and the jurisdiction in which such Subsidiary or






Joint Venture is organized.  Section 3.2 of the Company Letter also sets

Company has no obligation to make any capital contributions, or
otherwise provide assets or cash, to any Joint Venture.

          Section 3.3    Authority.  On or prior to the date of this
Agreement, the Board of Directors of the Company has declared the Merger
advisable and fair to and in the best interest of the Company and its
stockholders, approved and adopted this Agreement in accordance with the
DGCL, approved the Stockholder Agreements and the Stock Option
Agreement, resolved to recommend the approval and adoption of this
Agreement by the Company's stockholders and directed that this Agreement
be submitted to the Company's stockholders for approval and adoption.
The Company has all requisite corporate power and authority to enter
into this Agreement and the Stock Option Agreement, to consummate the
transactions contemplated by the Stock Option Agreement and, subject to
approval by the stockholders of the Company of this Agreement, to
consummate the transactions contemplated hereby.  The execution and
delivery of this Agreement and the Stock Option Agreement by the Company
and the consummation by the Company of the transactions contemplated
hereby and thereby have been duly authorized by all necessary corporate
action on the part of the Company, subject, in the case of this
Agreement, to (x) approval of this Agreement by the stockholders of the
Company and (y) the filing of appropriate Merger documents as required
by the DGCL. This Agreement and the Stock Option Agreement have been
duly executed and delivered by the Company and (assuming the valid
authorization, execution and delivery of this Agreement by Parent and
Sub and the Stock Option Agreement by Parent and the validity and
binding effect of the Agreement on Parent and Sub and the Stock Option
Agreement on Parent) constitute the valid and binding obligation of the
Company enforceable against the Company in accordance with its terms.
The filing of the Joint Proxy Statement with the SEC and the issuance of
the shares of Company Common Stock pursuant to the Stock Option
Agreement have been duly authorized by the Company's Board of Directors.

          Section 3.4    Consents and Approvals; No Violation.  Assuming
that all consents, approvals, authorizations and other actions described
in this Section 3.4 have been obtained and all filings and obligations
described in this Section 3.4 have been made, except as set forth in
Section 3.4 of the Company Letter, the execution and delivery of this
Agreement and the Stock Option Agreement do not, and the consummation of
the transactions contemplated hereby and thereby and compliance with the
provisions hereof and thereof will not, result in any violation of, or
default (with or without notice or lapse of time, or both) under, or
give to others a right of termination, cancellation or acceleration of
any obligation or the loss of a material benefit under, or result in the
creation of any lien, security interest, charge or encumbrance upon any
of the properties or assets of the Company or any of its Subsidiaries
under, any provision of (i) the Company Charter or the Company Bylaws,
(ii) any provision of the comparable charter or organization documents
of any of the Company's Subsidiaries, (iii) any loan or credit
agreement, note, bond, mortgage, indenture, lease or other agreement,
instrument, permit, concession, franchise or license applicable to the






Company or any of its Subsidiaries or (iv) any judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to the Company or
any of its Subsidiaries or any of their respective properties or assets,
other than, in the case of clauses (ii), (iii) or (iv), any such
violations, defaults, rights, liens, security interests, charges or
encumbrances that, individually or in the aggregate, would not have a
Material Adverse Effect on the Company, materially impair the ability of
the Company to perform its obligations hereunder or under the Stock
Option Agreement or prevent the consummation of any of the transactions
contemplated hereby or thereby.  No filing or registration with, or
authorization, consent or approval of, any Governmental Entity is
required by or with respect to the Company or any of its Subsidiaries in
connection with the execution and delivery of this Agreement or the
Stock Option Agreement by the Company or is necessary for the

may be required to obtain the State Takeover Approvals, (iv) such
filings as may be required in connection with the taxes described in
Section 5.11, (v) applicable requirements, if any, of Blue Sky Laws and
NASDAQ, (vi) as may be required under foreign laws and (vii) such other
consents, orders, authorizations, registrations, declarations and
filings the failure of which to be obtained or made would not,
individually or in the aggregate, have a Material Adverse Effect on the
Company, materially impair the ability of the Company to perform its
obligations hereunder or under the Stock Option Agreement or prevent the
consummation of any of the transactions contemplated hereby or thereby.

          Section 3.5    SEC Documents and Other Reports.  The Company
has timely filed all required documents with the SEC since February 7,
1997 (the "Company SEC Documents").  As of their respective dates, the

aggregate, would not have a Material Adverse Effect on the Company.

          (b)  Except as disclosed in the Company SEC Documents filed
prior to the date of this Agreement or as disclosed in Section 3.8 of
the Company Letter, as of the date hereof there is no contract or
agreement that is or was required to be filed by the Company as a
material contract pursuant to Item 601 of Regulation S-K under the

Letter, as of the date hereof neither the Company nor any of its

which, the Company or any of its Subsidiaries is entitled to conduct its
business or (ii) any agreement evidencing, or guarantee relating to,
indebtedness for borrowed money to the extent the aggregate principal
amount outstanding thereunder exceeds $10,000,000.  Except as set forth
in the Company SEC Documents filed prior to the date of this Agreement
or as disclosed in Section 3.8 of the Company Letter, no event of
default or event that, but for the giving of notice or the lapse of time
or both, would constitute an event of default exists or, upon the
consummation by the Company of the transactions contemplated by this
Agreement or the Stock Option Agreement, will exist under any indenture,






mortgage, loan agreement, note or other agreement or instrument for
borrowed money, any guarantee of any agreement or instrument for
borrowed money or any lease, contractual license or other agreement or
instrument to which the Company or any of its Subsidiaries is a party or
by which the Company or any such Subsidiary is bound or to which any of
the properties, assets or operations of the Company or any such
Subsidiary is subject, other than any defaults that, individually or in
the aggregate, would not have a Material Adverse Effect on the Company.

Subsidiaries have filed all federal, and all material state, local,
foreign and provincial, Tax Returns required to have been filed or

Tax Returns are correct and complete, except to the extent that any
failure to so file or any failure to be correct and complete would not,
individually or in the aggregate, have a Material Adverse Effect on the
Company; (ii) all Taxes shown to be due on such Tax Returns have been
timely paid or extensions for payment have been properly obtained,
except to the extent that any failure to so pay or so obtain such an

regulations relating to the withholding of Taxes except to the extent

individually or in the aggregate, have a Material Adverse Effect on the
Company; (iv) any Tax Returns referred to in clause (i) relating to
federal income Taxes have been examined by the IRS or the period for

and except as set forth in Section 3.10 of the Company Letter, there are
no outstanding orders, judgments, injunctions, awards or decrees of any
Governmental Entity against or involving the Company or any of its
Subsidiaries, or against or involving any of the present or former
directors, officers, employees or, to the Knowledge of the Company,
consultants, agents or stockholders of the Company or any of its
Subsidiaries, as such, or any of its or their properties, assets or
business or any Company Plan (as hereinafter defined) that, individually
or in the aggregate, would have a Material Adverse Effect on the Company
or materially impair the ability of the Company to perform its
obligations hereunder or under the Stock Option Agreement.  Except as






set forth in the Company SEC Documents filed prior to the date of this
Agreement or in Section 3.10 of the Company Letter, there are no
actions, suits or claims or legal, administrative or arbitration
proceedings or investigations pending or, to the Knowledge of the
Company, threatened against or involving the Company or any of its
Subsidiaries or any of its or their present or former directors,
officers, employees or, to the Knowledge of the Company, consultants,
agents or stockholders, as such, or any of its or their properties,
assets or business or any Company Plan that, individually or in the
aggregate, would have a Material Adverse Effect on the Company or
materially impair the ability of the Company to perform its obligations
hereunder or under the Stock Option Agreement.  As of the date hereof,
there are no actions, suits, labor disputes or other litigation, legal
or administrative proceedings or governmental investigations pending or,
to the Knowledge of the Company, threatened against or affecting the
Company or any of its Subsidiaries or any of its or their present or
former officers, directors, employees or, to the Knowledge of the
Company, consultants, agents or stockholders, as such, or any of its or
their properties, assets or business relating to the transactions
contemplated by this Agreement and the Stock Option Agreement.

          Section 3.11   Certain Agreements.  Except as set forth in
Section 3.11 of the Company Letter, neither the Company nor any of its
Subsidiaries is a party to any oral or written agreement or plan,
including any employment agreement, severance agreement, stock option
plan, stock appreciation rights plan, restricted stock plan or stock
purchase plan, any of the benefits of which will be increased, or the
vesting of the benefits of which will be accelerated, by the occurrence
of any of the transactions contemplated by this Agreement or the Stock
Option Agreement or the value of any of the benefits of which will be
calculated on the basis of any of the transactions contemplated by this
Agreement or the Stock Option Agreement.  No holder of any option to
purchase shares of Company Common Stock, or shares of Company Common
Stock granted in connection with the performance of services for the
Company or its Subsidiaries, is or will be entitled to receive cash from
the Company or any Subsidiary in lieu of or in exchange for such option
or shares under this Agreement or the Stock Option Agreement.  Section
3.11 of the Company Letter sets forth (i) for each officer, director,
employee or consultant who is a party to, or will receive benefits
under, this Agreement or the Stock Option Agreement, the total amount
that each such person may receive, or is eligible to receive, assuming
that the transactions contemplated by this Agreement are consummated on
the date hereof, and (ii) the total amount of indebtedness owed to the
Company or its Subsidiaries from each officer or director of the Company
and its Subsidiaries.  Except to the extent set forth in Section 3.11 of
the Company Letter, no "excess parachute payments" (as such term is
defined in Section 280G(b) of the Code) will be payable as a result of
the transactions contemplated by this Agreement to any employee of the
Company or its Subsidiaries who is a "disqualified individual" under
Section 280G of the Code.

          Section 3.12   ERISA.  (a) Each Company Plan is listed in
Section 3.12(a) of the Company Letter, true and complete copies of which
have heretofore been delivered to Parent.  Except as would not have a






Material Adverse Effect on the Company, (i) each Company Plan complies
in all respects with ERISA, the Code and all other applicable statutes
and governmental rules and regulations, and (ii) no "reportable event"
(within the meaning of Section 4043 of ERISA) has occurred with respect
to any Company Plan.  Neither the Company nor any of its ERISA
Affiliates (as defined in Section 2.12(c)) has withdrawn from any
Company Plan or Company Multiemployer Plan (as hereinafter defined) or
instituted, or is currently considering taking, any action to do so.  No
action has been taken, or is currently being considered, to terminate
any Company Plan subject to Title IV of ERISA.  No Company Plan, nor any
trust created thereunder, has incurred any "accumulated funding
deficiency" (as defined in Section 302 of ERISA), whether or not waived.

          (b)  Except as listed in Section 3.12(b) of the Company
Letter, with respect to the Company Plans, no event has occurred and, to
the Knowledge of the Company, there exists no condition or set of
circumstances in connection with which the Company or any ERISA
Affiliate or Company Plan fiduciary could be subject to any liability
under the terms of such Company Plans, ERISA, the Code or any other
applicable law, other than liabilities for benefits payable in the
normal course, which would have a Material Adverse Effect on the
Company.  All Company Plans that are intended to be qualified under
Section 401(a) of the Code have been determined by the IRS to be so
qualified, or a timely application for such determination is now
pending, and the Company is not aware of any reason why any such Company
Plan is not so qualified in operation.  Neither the Company nor any of
its ERISA Affiliates has been notified by any Company Multiemployer Plan
that such Company Multiemployer Plan is currently in reorganization or
insolvency under and within the meaning of Section 4241 or 4245 of ERISA
or that such Company Multiemployer Plan intends to terminate or has been
terminated under Section 4041A of ERISA.  Except as disclosed in Section
3.12(b) of the Company Letter, neither the Company nor any of its ERISA
Affiliates has any liability or obligation under any welfare plan to
provide benefits after termination of employment to any employee or
dependent other than as required by Section 4980B of the Code.

          (c)  As used herein, (i) "Company Plan" means a "pension plan"
(as defined in Section 3(2) of ERISA (other than a Company Multiemployer
Plan)), a "welfare plan" (as defined in Section 3(1) of ERISA), or any
bonus, profit sharing, deferred compensation, incentive compensation,
stock ownership, stock purchase, stock option, phantom stock, holiday
pay, vacation, severance, death benefit, sick leave, fringe benefit,
insurance or other plan, arrangement or understanding, in each case
established or maintained by the Company or any of its ERISA Affiliates
or as to which the Company or any of its ERISA Affiliates has
contributed or otherwise may have any liability, and (ii) "Company
Multiemployer Plan" means a "multiemployer plan" (as defined in Section
4001(a)(3) of ERISA) to which the Company or any of its ERISA Affiliates
is or has been obligated to contribute or otherwise may have any
liability.

          (d)  Section 3.12(d) of the Company Letter contains a list,
and the Company has heretofore provided to Parent a true and complete
copy, of all (i) severance, employment and material consulting






agreements with employees and consultants of the Company and each of its
ERISA Affiliates and (ii) severance programs and policies of the Company
and each of its ERISA Affiliates with or relating to its employees.  The
Company has entered into a Proprietary Information Agreement with each
of Steve W. Chaddick and Larry P. Huang (the "Noncompetition
Agreements"), true and complete copies of which (including all
amendments thereto) are attached to Section 3.12(d) of the Company
Letter.

          Section 3.13   Compliance with Worker Safety and Environmental
Laws.  The properties, assets and operations of the Company and its
Subsidiaries are in compliance with all applicable Worker Safety Laws
and Environmental Laws, except for any violations that, individually or
in the aggregate, would not have a Material Adverse Effect on the
Company.  With respect to such properties, assets and operations,
including any previously owned, leased or operated properties, assets or
operations, there are no events, conditions, circumstances, activities,
practices, incidents, actions or plans of the Company or any of its
Subsidiaries that may interfere with or prevent compliance or continued
compliance with applicable Worker Safety Laws and Environmental Laws,
other than any such interference or prevention as would not,
individually or in the aggregate with any such other interference or
prevention, have a Material Adverse Effect on the Company.

          Section 3.14   Labor Matters.  Neither the Company nor any of
its Subsidiaries is a party to any collective bargaining agreement or,
except as set forth in Section 3.14 of the Company Letter, any labor
contract.  Neither the Company nor any of its Subsidiaries has engaged
in any unfair labor practice with respect to any persons employed by or
otherwise performing services primarily for the Company or any of its
Subsidiaries (the "Company Business Personnel"), and there is no unfair
labor practice complaint or grievance against the Company or any of its
Subsidiaries by the National Labor Relations Board or any comparable
state agency pending or threatened in writing with respect to the
Company Business Personnel, except where such unfair labor practice,
complaint or grievance would not have a Material Adverse Effect on the
Company.  There is no labor strike, dispute, slowdown or stoppage
pending or, to the Knowledge of the Company, threatened against or
affecting the Company or any of its Subsidiaries which may interfere
with the respective business activities of the Company or any of its
Subsidiaries, except where such dispute, strike or work stoppage would
not have a Material Adverse Effect on the Company.

          Section 3.15   Intellectual Property.  (a) Except as set forth
in Section 3.15 of the Company Letter, the Company and its Subsidiaries
have through ownership or licensing all Intellectual Property Rights as
are necessary to conduct the business of the Company and its
Subsidiaries as currently conducted or planned to be conducted by the
Company and its Subsidiaries, taken as a whole, except where the failure
to have such Intellectual Property Rights would not have a Material
Adverse Effect on the Company.  Except as set forth in Section 3.15 of
the Company Letter, neither the Company nor any of its Subsidiaries has








infringed any Intellectual Property Rights of any third party other than
any infringements that, individually and in the aggregate, would not
have a Material Adverse Effect on the Company.

          (b)  Except as set forth in the Company SEC Documents filed
prior to the date of this Agreement or in Section 3.15 of the Company
Letter, there are no actions, suits or claims or administrative
proceedings or investigations pending or, to the Knowledge of the
Company, threatened that challenge or question the Company's
Intellectual Property Rights and that, individually or in the aggregate,
would have a Material Adverse Effect on the Company.

          (c) All patents, registered trademarks, service marks and
copyrights which are held by the Company or any of its Subsidiaries, and
which are material to the business of the Company and its Subsidiaries,
taken as a whole, are to the Knowledge of the Company valid and
subsisting.  Section 3.15 of the Company Letter contains a list as of
the date hereof of (i) all material registered United States, state and
foreign trademarks, service marks, logos, trade dress and trade names
and pending applications to register the foregoing, (ii) all United
States and material foreign patents and patent applications and (iii)
all material registered United States and foreign copyrights and pending
applications to register the same, in each case owned by the Company and
its Subsidiaries.  The statements set forth in Section 3.15(c) of the
Company Letter are true and correct. 

          Section 3.16   Opinion of Financial Advisor.  The Company has
received the written opinion of Morgan Stanley & Co.  Incorporated,
dated the date hereof, to the effect that, as of the date hereof, the
Exchange Ratio is fair to the Company's stockholders from a financial
point of view, a copy of which opinion has been delivered to Parent.

          Section 3.17   State Takeover Statutes; Certain Charter
Provisions.  The Board of Directors of the Company has, to the extent
such statutes are applicable, taken all action (including appropriate
approvals of the Board of Directors of the Company) necessary to exempt
Parent, its Subsidiaries and affiliates, the Merger, this Agreement, the
Stock Option Agreement, the Stockholder Agreements and the transactions
contemplated hereby and thereby from Section 203 of the DGCL. To the
Knowledge of the Company, no other state takeover statutes or charter or
bylaw provisions are applicable to the Merger, this Agreement, the Stock
Option Agreement, the Stockholder Agreements and the transactions
contemplated hereby and thereby.

          Section 3.18   Required Vote of Company Stockholders.  The
affirmative vote of the holders of a majority of the outstanding shares
of Company Common Stock is required to adopt this Agreement.  No other
vote of the securityholders of the Company is required by law, the
Company Charter or the Company Bylaws or otherwise in order for the
Company to consummate the Merger and the transactions contemplated
hereby and in the Stock Option Agreement.

          Section 3.19   Pooling of Interests; Reorganization.  To the
knowledge of the Company, neither it nor any of its Subsidiaries has






(i) taken any action or failed to take any action which action or
failure would jeopardize the treatment of the Merger as a pooling of
interests for accounting purposes or (ii) taken any action or failed to
take any action which action or failure would jeopardize the
qualification of the Merger as a reorganization within the meaning of
Section 368(a) of the Code.

          Section 3.20   Brokers.  No broker, investment banker or other
person, other than Morgan Stanley & Co.  Incorporated, the fees and
expenses of which will be paid by the Company (as reflected in an
agreement between Morgan Stanley & Co.  Incorporated and the Company, a
copy of which has been furnished to Parent), is entitled to any
broker's, finder's or other similar fee or commission in connection with
the transactions contemplated by this Agreement and by the Stock Option
Agreement based upon arrangements made by or on behalf of the Company.

          Section 3.21 Rights Agreement.  The Company has amended the
Rights Agreement to (i) render the Rights Agreement inapplicable to the
Merger, the Stock Option Agreement, the Stockholder Agreements and the
transactions contemplated hereby and thereby, (ii) provide that Parent
shall not be deemed an Acquiring Person (as defined in the Rights
Agreement), the Distribution Date (as defined in the Rights Agreement)
shall not be deemed to occur and the Rights will not separate from the
shares of Company Common Stock as a result of entering into this
Agreement, the Stock Option Agreement, the Stockholder Agreements or
consummating the transactions contemplated hereby or thereby and (iii)
provide that the Rights shall cease to be exercisable immediately prior
to the Effective Time.

          Section 4.2    No Solicitation.  (a) From the date hereof
until the earlier of the Effective Time or the date on which this
Agreement is terminated in accordance with the terms hereof, the Company
shall not, nor shall it permit any of its Subsidiaries to, nor shall it
authorize or permit any officer, director or employee of or any
financial advisor, attorney or other advisor or representative of, the
Company or any of its Subsidiaries to, (i) solicit, initiate or

hereafter defined), (ii) enter into any agreement with respect to any
Takeover Proposal or (iii) participate in any discussions or
negotiations regarding, or furnish to any person any information with
respect to, or take any other action to knowingly facilitate any
inquiries or the making of any proposal that constitutes, or may
reasonably be expected to lead to, any Takeover Proposal; provided,






however, that prior to the Company Stockholder Meeting, nothing
contained in this Agreement (including, without limitation Section
4.1(a)) shall prevent the Company or its Board of Directors from (i)
complying with Rules 14d-9 and 14e-2 under the Exchange Act or publicly
disclosing the existence of a Takeover Proposal to the extent required
by applicable law or (ii) furnishing non-public information to, or
entering into discussions or negotiations with, any person or entity in
connection with an unsolicited bona fide written Takeover Proposal by
such person or entity, if and only to the extent that, with respect to
clause (ii) above, (w) such Takeover Proposal would, if consummated,
result in a transaction that would, in the reasonable good faith
judgment of the Board of Directors of the Company, after consultation
with its financial advisors, result in a transaction more favorable to
the Company's stockholders from a financial point of view than the
Merger (any such more favorable Takeover Proposal being referred to in
this Agreement as a "Superior Proposal") and, in the reasonable good
faith judgment of the Board of Directors of the Company, after
consultation with its financial advisors, the person or entity making
such Superior Proposal has the financial means to conclude such
transaction, (x) the failure to take such action would in the reasonable
good faith judgment of the Board of Directors of the Company, on the
basis of the advice of the outside corporate counsel of the Company,
violate the fiduciary duties of the Board of Directors of the Company to
the Company's stockholders under applicable law, (y) prior to furnishing
such non-public information to, or entering into discussions or
negotiations with, such person or entity, such Board of Directors
receives from such person or entity an executed confidentiality
agreement with provisions not less favorable to the Company than those
contained in the Confidentiality Agreement (as defined below) and (z)
the Company shall have fully complied with this Section 4.2.  For
purposes of this Agreement, "Takeover Proposal" means any proposal or
offer, or any expression of interest, by any third party relating to the
Company's willingness or ability to receive or discuss a proposal or
offer for a merger, consolidation or other business combination
involving the Company or any of its Subsidiaries or any proposal or
offer to acquire in any manner, directly or indirectly, a substantial
equity interest in, a substantial portion of the voting securities of,
or a substantial portion of the assets of the Company or any of its
Subsidiaries, other than the transactions contemplated by this Agreement
and the Stock Option Agreement.

          (b)  The Company shall advise Parent orally (within one
business day) and in writing (as promptly as practicable) of (i) any
Takeover Proposal or any inquiry with respect to or which could lead to
any Takeover Proposal, (ii) the material terms of such Takeover Proposal
and (iii) the identity of the person making any such Takeover Proposal
or inquiry.  The Company will keep Parent fully informed of the status
and details of any such Takeover Proposal or inquiry.

          Section 4.3    Third Party Standstill Agreements.  During the
period from the date of this Agreement through the Effective Time, the
Company shall not terminate, amend, modify or waive any provision of any
confidentiality agreement relating to a Takeover Proposal or standstill
agreement to which the Company or any of its Subsidiaries is a party






(other than any involving Parent).  During such period, the Company
agrees to enforce, to the fullest extent permitted under applicable law,
the provisions of any such agreements, including, but not limited to,
obtaining injunctions to prevent any breaches of such agreements and to
enforce specifically the terms and provisions thereof in any court of
the United States or any state thereof having jurisdiction.

          Section 4.4    Pooling of Interests; Reorganization.  During
the period from the date of this Agreement through the Effective Time,
unless the other party shall otherwise agree in writing, none of Parent,
the Company or any of their respective Subsidiaries shall (a) knowingly
take or fail to take any action which action or failure would jeopardize
the treatment of the Merger as a pooling of interests for accounting
purposes or (b) knowingly take or fail to take any action which action
or failure would jeopardize the qualification of the Merger as a
reorganization within the meaning of Section 368(a) of the Code.
Between the date of this Agreement and the Effective Time, Parent and
the Company each shall take, or cause to be taken, all actions
reasonably necessary in order for the Merger to be treated as a pooling
of interests for accounting purposes.


                              ARTICLE V

                         ADDITIONAL AGREEMENTS


          Section 5.1    Stockholder Meetings.  The Company and Parent
will each, as soon as practicable following the date of this Agreement,
duly call, give notice of, convene and hold a meeting of stockholders
(respectively, the "Company Stockholder Meeting" and the "Parent
Stockholder Meeting" and, collectively, the "Stockholder Meetings") for
the purpose of considering the approval of this Agreement (in the case
of the Company) and the Share Issuance (in the case of Parent).  The
Company and Parent shall coordinate and cooperate with respect to the
timing of such meetings and shall use their reasonable best efforts to
hold such meetings on the same day.  Parent will, through its Board of
Directors, recommend to its stockholders approval of the Share Issuance,
shall use all reasonable efforts to solicit such approval by its
stockholders and shall not withdraw or modify, or propose to withdraw or
modify in a manner adverse to the Company, such recommendation, except
if in the reasonable good faith judgment of Parent's Board of Directors,
on the basis of the advice of outside corporate counsel of Parent, the
making of, or the failure to withdraw or modify, such recommendation
would violate the fiduciary duties of such Board of Directors to
Parent's stockholders under applicable law.  Parent agrees to submit the
Share Issuance to its stockholders for approval whether or not the Board
of Directors of Parent determines at any time subsequent to the date
hereof and in accordance with the preceding sentence that the Share
Issuance is no longer advisable and recommends that the stockholders of
Parent reject it.  The Company will, through its Board of Directors,
recommend to its stockholders approval of this Agreement, shall use all
reasonable efforts to solicit such approval by its stockholders and
shall not withdraw or modify, or propose to withdraw or modify in a






manner adverse to Parent, such recommendation, except if (i) the Company
has complied with Section 4.2 and (ii) (A) in the reasonable good faith
judgment of the Company's Board of Directors, on the basis of the advice
of outside corporate counsel of the Company, the making of, or the
failure to withdraw or modify, such recommendation would violate the
fiduciary duties of such Board of Directors to the Company's
stockholders under applicable law or (B) (x) the Board of Directors of
the Company, after due deliberation and in the good faith exercise of
its fiduciary duties under applicable law (as advised by outside
corporate counsel of the Company), determines (1) to withdraw or modify
such recommendation solely because Parent notifies the Company that it
intends to enter into or has entered into a definitive written agreement
to effect a Parent Acquisition Event (as defined herein) and (2) that,
solely as a result of such Parent Acquisition Event, the Merger is no
longer in the best interests of the Company and its stockholders and (y)
the Board of Directors of the Company notifies Parent that it has
resolved to withdraw or modify its recommendation in favor of the
approval of this Agreement within five business days of the receipt of
Parent's notice.  In the event Parent subsequently notifies the Company
that it has elected not to enter into such definitive written agreement
to effect the Parent Acquisition Event, the Board of Directors of the
Company shall rescind any resolution to withdraw or modify its
recommendation in favor of approval of this Agreement.  The Company
agrees to submit the Merger Agreement to its stockholders for approval
whether or not the Board of Directors of the Company determines at any
time subsequent to the date hereof and in accordance with the terms of
this Section 5.1 that the Merger Agreement is no longer advisable and
recommends that the stockholders of the Company reject it.

          Section 5.2    Preparation of the Registration Statement and
the Joint Proxy Statement.  The Company and Parent shall promptly
prepare and file with the SEC the Joint Proxy Statement and Parent shall
prepare and file with the SEC the Registration Statement, in which the
Joint Proxy Statement will be included as a prospectus.  Each of Parent
and the Company shall use its reasonable best efforts to have the
Registration Statement declared effective under the Securities Act as
promptly as practicable after such filing.  As promptly as practicable
after the Registration Statement shall have become effective, each of
Parent and the Company shall mail the Joint Proxy Statement to its
respective stockholders.  Parent shall also take any action reasonably
required to be taken under any applicable state securities laws in
connection with the issuance of Parent 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.

          Section 5.3    Intentionally Omitted.

          Section 5.4    Access to Information.  Subject to currently
existing contractual and legal restrictions applicable to Parent or to
the Company or any of their respective Subsidiaries, as the case may be,
each of Parent and the Company shall, and shall cause each of its
Subsidiaries to, afford to the accountants, counsel, financial advisors
and other representatives of the other reasonable access to, and permit






them to make such inspections as they may reasonably require of, during
normal business hours during the period from the date of this Agreement
through the Effective Time, all of its properties, books, contracts,
commitments and records (including, without limitation, the work papers
of independent accountants, if available and subject to the consent of
such independent accountants) and, during such period, each of Parent
and the Company shall, and shall cause each of its Subsidiaries to,
furnish promptly to the other (i) a copy of each report, schedule,
registration statement and other document filed by it during such period
pursuant to the requirements of federal or state securities laws and
(ii) all other information concerning its business, properties and
personnel as the other may reasonably request.  No investigation
pursuant to this Section 5.4 shall affect any representation or warranty
in this Agreement of any party hereto or any condition to the
obligations of the parties hereto.  All information obtained pursuant to
this Section 5.4 shall be kept confidential in accordance with the
Confidentiality Agreement, dated May 14, 1998 between Parent and the
Company (the "Confidentiality Agreement").

          Section 5.5    Compliance with the Securities Act.  (a)
Section 5.5(a) of the Company Letter contains a list identifying all
persons who, at the time of the Company Stockholder Meeting, may be
deemed to be "affiliates" of the Company as that term is used in
paragraphs (c) and (d) of Rule 145 under the Securities Act (the "Rule
145 Affiliates").  The Company shall use its reasonable best efforts to
cause each person who is identified as a Rule 145 Affiliate in such list
to deliver to Parent within 30 days of the date hereof a written
agreement in substantially the form of Exhibit 5.5(a) hereto (the
"Company Affiliate Letter"), executed by each of such persons identified
in the foregoing list.  Prior to the Effective Time, the Company shall
amend and supplement Section 5.5(a) of the Company Letter and use its
reasonable best efforts to cause each additional person who is
identified as a Rule 145 Affiliate of the Company to execute the Company
Affiliate Letter.  Parent shall be entitled to place appropriate legends
on the certificates evidencing any Parent Common Stock to be received by
affiliates of the Company pursuant to this Agreement and to issue
appropriate stop transfer instructions to the transfer agent for the
Parent Common Stock, consistent with the terms of the Company Affiliate
Letter.

          (b)  Section 5.5(b) of the Parent Letter contains a list
identifying those persons who may be, at the time of the Parent
Stockholder Meeting, affiliates of Parent under applicable SEC
accounting releases with respect to pooling of interests accounting
treatment.  Parent shall use its reasonable best efforts to enter into a
written agreement in substantially the form of Exhibit 5.5(b) hereto
(the "Parent Affiliate Letter") within 30 days of the date hereof with
each of such persons identified in the foregoing list.  Prior to the
Effective Time, Parent shall amend and supplement Section 5.5(b) of the
Parent Letter and use its reasonable best efforts to cause each
additional person who is identified as an affiliate of Parent to execute
the Parent Affiliate Letter.








          Section 5.6    Current Nasdaq Quotation.  Each of Parent and
the Company shall use its reasonable best efforts to continue the
quotation of the Parent Common Stock and the Company Common Stock,
respectively, on NASDAQ during the term of this Agreement to the extent
necessary so that appraisal rights will not be available to stockholders
of the Company under Section 262 of the DGCL.

          Section 5.7    Fees and Expenses.  (a) Except as provided in
this Section 5.7 and Section 5.11, whether or not the Merger is
consummated, all costs and expenses incurred in connection with this
Agreement and the transactions contemplated hereby including, without
limitation, the fees and disbursements of counsel, financial advisors
and accountants, shall be paid by the party incurring such costs and
expenses, provided that all printing expenses and all filing fees
(including, without limitation, filing fees under the Securities Act,
the Exchange Act and the HSR Act) shall be divided equally between
Parent and the Company.

          (b)  (i) Notwithstanding any provision in this Agreement to
the contrary, if this Agreement is terminated (A) by the Company or
Parent pursuant to Section 7.1(e) and a Takeover Proposal existed
between the date hereof and the date of the Company Stockholder Meeting,
(B) by the Company or Parent pursuant to Section 7.1(g) or (C) by Parent
pursuant to Section 7.1(h)(except, in the case of Section 7.1(h)(i), as
provided in Section 5.7(d)), then, in each case, the Company shall
(without prejudice to any other rights Parent may have against the
Company for breach of this Agreement) reimburse Parent upon demand for
all reasonable out-of-pocket fees and expenses incurred or paid by or on
behalf of Parent or any Affiliate (as hereinafter defined) of Parent in
connection with this Agreement, the Stock Option Agreement and the
transactions contemplated herein or therein, including all fees and
expenses of counsel, investment banking firms, accountants and
consultants; provided, however, that the Company shall not be obligated
to make payments pursuant to this Section 5.7(b)(i) in excess of
$10,000,000 in the aggregate.  As used herein, "Affiliate" shall have
the meaning set forth in Rule 405 under the Securities Act.

          (ii) Notwithstanding any provision in this Agreement to the
contrary, if this Agreement is terminated (A) by the Company or Parent
pursuant to Section 7.1(f) and a Parent Takeover Proposal (as defined
below) existed between the date hereof and the date of the Parent
Stockholder Meeting or (B) by the Company pursuant to Section 7.1(i)
(except in circumstances in which the event described in Section 7.1(i)
causing such termination occurred solely as a result of a Material
Adverse Effect on the Company (provided that, for purposes of this
Section 5.7(b)(ii)(B), a Material Adverse Effect on the results of
operations of the Company and its Subsidiaries shall only be deemed to
be such to the extent it relates to the long-term prospects of the
results of operations of the Company and its Subsidiaries taken as a
whole) after the Board of Directors of Parent determined, in its
reasonable good faith judgment, on the basis of the advice of outside
corporate counsel of Parent, that the making of its recommendation to
the stockholders of Parent in favor of the Share Issuance, or the
failure to withdraw or modify such recommendation, would violate its






fiduciary duties under applicable law in light of such Material Adverse
Effect on the Company), then, in each case, Parent shall (without
prejudice to any other rights the Company may have against Parent for
breach of this Agreement) reimburse the Company upon demand for all
reasonable out-of-pocket fees and expenses incurred or paid by or on
behalf of the Company or any Affiliate of the Company in connection with
this Agreement, the Stock Option Agreement and the transactions
contemplated herein or therein, including all fees and expenses of
counsel, investment banking firms, accountants and consultants;
provided, however, that Parent shall not be obligated to make payments
pursuant to this Section 5.7(b)(ii) in excess of $10,000,000 in the
aggregate.  As used herein, "Parent Takeover Proposal" means any
proposal or offer, or any expression of interest, by any third party
relating to Parent's willingness or ability to receive or discuss a
proposal or offer for a merger, consolidation or other business
combination, in each case pursuant to which Parent is acquired by a
third party.

          (c)  Notwithstanding any provision in this Agreement to the
contrary, if (i) this Agreement is terminated by the Company or Parent
pursuant to Section 7.1(e) and a Takeover Proposal existed between the
date hereof and the date of the Company Stockholder Meeting and,
concurrently with or within twelve months after any such termination a
Third Party Acquisition Event (as defined below) occurs or the Company
shall enter into any letter of intent, agreement in principle,
acquisition agreement or other similar agreement with respect to a Third
Party Acquisition Event, (ii) this Agreement is terminated by Parent or
the Company pursuant to Section 7.1(g) or (iii) this Agreement is
terminated by Parent pursuant to Section 7.1(h) (except, in the case of
Section 7.1(h)(i), as provided in Section 5.7(d)), then, in each case,
the Company shall (in addition to any obligation under Section 5.7(b)
and without prejudice to any other rights that Parent may have against
the Company for a breach of this Agreement) pay to Parent a fee (the
"Termination Fee") of $200,000,000 in cash, such payment to be made
promptly, but in no event later than, in the case of clause (i), the
later to occur of such termination and such Third Party Acquisition
Event or, in the case of clauses (ii) or (iii), such termination.

          As used in this Agreement, a  "Third Party Acquisition Event"
involving the Company means (i) a transaction or series of transactions
pursuant to which any person or group (as such term is defined under the
Exchange Act), other than Parent or Sub, or any affiliate thereof
("Third Party"), acquires (or would acquire upon completion of such
transaction or series of transactions) more than twenty percent (20%) of
the equity securities or voting power of the Company or any of its
Subsidiaries, pursuant to a tender offer or exchange offer or otherwise,
(ii) a merger, consolidation, share exchange or other business
combination involving the Company or any of its Subsidiaries pursuant to
which any person other than Parent or Sub acquires ownership (or would
acquire ownership upon consummation of such merger, consolidation, share
exchange or other business combination) of more than twenty percent
(20%) of the outstanding equity securities or voting power of the
Company or any of its Subsidiaries or of the entity surviving such
merger or business combination or resulting from such consolidation,






(iii) any other transaction or series of transactions pursuant to which
any Third Party acquires (or would acquire upon completion of such
transaction or series of transactions) control of assets of the Company
or any of its Subsidiaries (including, for this purpose, outstanding
equity securities of Subsidiaries of such party) having a fair market
value equal to more than twenty percent (20%) of the fair market value
of all the consolidated assets of the Company immediately prior to such
transaction or series of transactions, or (iv) any transaction or series
of transactions pursuant to which any Third Party acquires (or would
acquire upon completion of such transaction or series of transactions)
control of the Board of Directors of the Company or by which nominees of
any Third Party are (or would be) elected or appointed to a majority of
the seats on the Board of Directors of the Company.

          (d)  No payment shall be required to be made by the Company
pursuant to Section 5.7(b)(i)(C) or 5.7(c)(iii) (in each case, with
respect to a termination of this Agreement pursuant to Section
7.1(h)(i)) if the following conditions are satisfied: (i) no Takeover
Proposal existed between the date hereof and the date of the Company
Stockholder Meeting; (ii) the event described in Section 7.1(h)(i)
causing the termination of this Agreement occurred solely as a result of
(A) the occurrence of a Material Adverse Effect on Parent (provided
that, for purposes of this Section 5.7(d)(ii)(A), a Material Adverse
Effect on the results of operations of Parent and its Subsidiaries shall
only be deemed to be such to the extent it relates to the long-term
prospects of the results of operations of Parent and its Subsidiaries
taken as a whole) or (B) Parent entering into a definitive written
agreement pursuant to which (x) Parent acquires, or one of Parent's
Subsidiaries merges with, another entity and (y) in consideration
therefor Parent agrees to issue Parent Common Stock or other voting
securities representing, in the aggregate, 20% or more of the then
outstanding shares of Parent Common Stock and other Parent voting
securities (a "Parent Acquisition Event"); (iii) prior to the occurrence
of the event described in Section 7.1(h)(i) causing the termination of
this Agreement (if resulting from such Material Adverse Effect on Parent
as stated above), the Board of Directors of the Company determined in
its reasonable good faith judgment, on the basis of the advice of
outside corporate counsel of the Company, that the making of its
recommendation to the stockholders of the Company in favor of approval
of this Agreement, or the failure to withdraw or modify such
recommendation, would violate its fiduciary duties under applicable law
solely in light of the Material Adverse Effect on Parent; and (iv) prior
to the occurrence of the event described in Section 7.1(h)(i) causing
such termination (if resulting from Parent entering into a definitive
written agreement to effect a Parent Acquisition Event as stated above),
(A) the Board of Directors of the Company, after due deliberation and in
the good faith exercise of its fiduciary duties under applicable law (as
advised by outside corporate counsel of the Company), determined (1) to
withdraw or modify such recommendation solely because Parent notified
the Company that it intended to enter into or had entered into a
definitive written agreement to effect a Parent Acquisition Event and
(2) that, solely as a result of such Parent Acquisition Event, the
Merger was no longer in the best interests of the Company and its
stockholders and (B) the Board of Directors of the Company notified






Parent that it had resolved to withdraw or modify its recommendation in
favor of the approval of this Agreement within five business days of the
receipt of Parent's notice.

          Section 5.8    Company Stock Plans.  (a) Not later than the
Effective Time, each Company Stock Option which is outstanding
immediately prior to the Effective Time pursuant to the Company Stock
Option Plans shall become and represent an option to purchase the number
of shares of Parent Common Stock (a "Substitute Option") (decreased to
the nearest full share) determined by multiplying (i) the number of
shares of Company Common Stock subject to such Company Stock Option
immediately prior to the Effective Time by (ii) the Exchange Ratio, at
an exercise price per share of Parent Common Stock (rounded up to the
nearest tenth of a cent) equal to the exercise price per share of
Company Common Stock immediately prior to the Effective Time divided by
the Exchange Ratio.  Parent shall pay cash to holders of Company Stock
Options in lieu of issuing fractional shares of Parent Common Stock upon
the exercise of Substitute Options for shares of Parent Common Stock,
unless in the judgment of Parent such payment would adversely affect the
ability to account for the Merger under the pooling of interests method.
After the Effective Time, except as provided above in this Section 5.8,
each Substitute Option shall be exercisable upon the same terms and
conditions as were applicable under the related Company Stock Option
immediately prior to or at the Effective Time.  The Company shall take
all necessary action to implement the provisions of this Section 5.8.
As soon as reasonably practicable, and in no event later than twenty
days after the Effective Time, Parent shall file a registration
statement on Form S-8 (or any successor or other appropriate form) with
respect to Parent Common Stock subject to such Substitute Options, or
shall cause such Substitute Options to be deemed to be issued pursuant
to a Parent Stock Plan for which shares of Parent Common Stock have been
previously registered pursuant to an appropriate registration form.

          (b)  The Company shall cause the Company Stock Purchase Plan
and all rights thereunder to terminate, with the effect of such
termination being that no offering period and no purchase period shall
commence under such plan.

          Section 5.9    Reasonable Best Efforts; Pooling of Interests.
(a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use 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 and the other
transactions contemplated by this Agreement, including, but not limited
to: (i) the obtaining of all necessary actions or non-actions, waivers,
consents and approvals from all Governmental Entities and the making of
all necessary registrations and filings (including filings with
Governmental Entities) and the taking of all reasonable steps as may be
necessary to obtain an approval or waiver from, or to avoid an action or
proceeding by, any Governmental Entity (including those in connection
with the HSR Act and State Takeover Approvals), (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, the Stock Option
Agreement or the consummation of the transactions contemplated hereby
and thereby, including seeking to have any stay or temporary restraining
order entered by any court or other Governmental Entity vacated or
reversed, (iv) each of Parent and the Company agreeing to take, together
with their respective accountants, all actions reasonably necessary in
order to obtain a favorable determination (if required) from the SEC
that the Merger may be accounted for as a pooling of interests in
accordance with generally accepted accounting principles and (v) the
execution and delivery of any additional instruments necessary to
consummate the transactions contemplated by this Agreement.  No party to
this Agreement shall consent to any voluntary delay of the consummation
of the Merger at the behest of any Governmental Entity without the
consent of the other parties to this Agreement, which consent shall not
be unreasonably withheld.

          (b)  Each party shall use all reasonable best efforts to not
take any action, or enter into any transaction, which would cause any of
its representations or warranties contained in this Agreement to be
untrue or result in a breach of any covenant made by it in this
Agreement.

          (c)  Notwithstanding anything to the contrary contained in
this Agreement, in connection with any filing or submission required or
action to be taken by either Parent or the Company to effect the Merger
and to consummate the other transactions contemplated hereby, the
Company shall not, without Parent's prior written consent, and Parent
shall not, without the Company's prior written consent, commit to any
divestiture transaction, and neither Parent or any of its Affiliates nor
the Company or any of its Affiliates shall be required to divest or hold
separate or otherwise take or commit to take any action that limits its
freedom of action with respect to, or its ability to retain, the Company
or any of the businesses, product lines or assets of Parent, the Company
or any of their respective Subsidiaries or that otherwise would have a
Material Adverse Effect on Parent or the Company.

          (d)  Nothing contained in this Agreement, including without
limitation this Section 5.9, shall limit or restrict Parent's ability to
enter into any Parent Takeover Proposal, any Parent Acquisition Event or
any other business combination or Parent's activities in connection with
any of the foregoing; provided, however, that this Section 5.9(d) shall
not affect the right of the Board of Directors of the Company to
withdraw or modify its recommendation to the stockholders of the Company
in favor of approval of this Agreement in accordance with the terms of
Section 5.1.

          Section 5.10   Public Announcements.  Parent and the Company
will not issue any press release with respect to the transactions
contemplated by this Agreement or otherwise issue any written public
statements with respect to such transactions without prior consultation
with the other party, except as may be required by applicable law or by
obligations pursuant to any listing agreement with any national
securities exchange or the rules of NASDAQ.







          Section 5.11   Real Estate Transfer and Gains Tax.  Parent and
the Company agree that either the Company or the Surviving Corporation
will pay any state or local tax which is attributable to the transfer of
the beneficial ownership of the Company's or its Subsidiaries' real
property, if any (collectively, the "Gains Taxes"), and any penalties or
interest with respect to the Gains Taxes, payable in connection with the
consummation of the Merger.  The Company and Parent agree to cooperate
with the other in the filing of any returns with respect to the Gains
Taxes, including supplying in a timely manner a complete list of all
real property interests held by the Company and its Subsidiaries and any
information with respect to such property that is reasonably necessary
to complete such returns.  The portion of the consideration allocable to
the real property of the Company and its Subsidiaries shall be
determined by Parent in its reasonable discretion.

          Section 5.12   State Takeover Laws.  If any "fair price,"
"business combination" or "control share acquisition" statute or other
similar statute or regulation shall become applicable to the
transactions contemplated hereby or in the Stock Option Agreement,
Parent and the Company and their respective Boards of Directors shall
use their reasonable best efforts to grant such approvals and take such
actions as are necessary so that the transactions contemplated hereby
and thereby may be consummated as promptly as practicable on the terms
contemplated hereby and thereby and otherwise act to minimize the
effects of any such statute or regulation on the transactions
contemplated hereby and thereby.

          Section 5.13   Indemnification; Directors and Officers
Insurance.  For six years from and after the Effective Time, Parent
agrees to cause the Surviving Corporation to indemnify and hold harmless
all past and present officers and directors of the Company and of its
Subsidiaries to the same extent such persons are indemnified as of the
date of this Agreement by the Company for acts or omissions occurring at
or prior to the Effective Time pursuant to the Company Charter, the
Company Bylaws and the indemnification agreements in the form filed as
an exhibit to the Company SEC Documents which were entered into prior to
the date hereof between the Company and persons identified in Section
5.13 of the Company Letter.  Parent shall provide, or shall cause the
Surviving Corporation to provide, for an aggregate period of not less
than six years from the Effective Time, the Company's current directors
and officers an insurance and indemnification policy that provides
coverage for events occurring prior to the Effective Time (the "D&O
Insurance") that is substantially similar (with respect to limits and
deductibles) to the Company's existing policy or, if substantially
equivalent insurance coverage is unavailable, the best available
coverage; provided, however, that the Surviving Corporation shall not be
required to pay an annual premium for the D&O Insurance in excess of
$1,425,000, but shall, in such event, maintain all coverage that can be
purchased for such amount.  The Company represents and warrants to
Parent that a true and complete copy of the Company's existing insurance
and indemnification policy has been provided to Parent.








          Section 5.14   Notification of Certain Matters.  Parent shall
use its reasonable best efforts to give prompt notice to the Company,
and the Company shall use its reasonable best efforts to give prompt
notice to Parent, of: (i) the occurrence, or non-occurrence, of any
event the occurrence, or non-occurrence, of which it is aware and which
would be reasonably likely to cause (x) any representation or warranty
contained in this Agreement to be untrue or inaccurate in any material
respect or (y) any covenant, condition or agreement contained in this
Agreement not to be complied with or satisfied in all material respects,
(ii) any failure of Parent or the Company, as the case may be, to comply
in a timely manner with or satisfy any covenant, condition or agreement
to be complied with or satisfied by it hereunder or (iii) any change or
event which would be reasonably likely to have a Material Adverse Effect
on Parent or the Company, as the case may be; provided, however, that
the delivery of any notice pursuant to this Section 5.14 shall not limit
or otherwise affect the remedies available hereunder to the party
receiving such notice.

          Section 5.15   Employee Benefit Plans and Agreements.  (a)
Parent agrees that it will cause the Surviving Corporation from and
after the Effective Time to honor all Company Plans and all employment
agreements entered into by the Company prior to the date hereof;
provided, however, that nothing in this Agreement shall be interpreted
as limiting the power of Parent or the Surviving Corporation to amend or
terminate any Company Plan or any other individual employee benefit
plan, program, agreement or policy or as requiring Parent or the
Surviving Corporation to offer to continue (other than as required by
its terms) any written employment contract.

          (b)  Subject to this Section 5.15(b),  Parent agrees that  
all employees of the Company and its Subsidiaries who are covered under
any of the Company Plans immediately prior to the Effective Time shall
continue to be covered under such Company Plans after the Effective Time
other than the Company Stock Purchase Plan and the Company Stock Option
Plans.  Notwithstanding the foregoing, Parent may terminate all of the
Company Plans provided that: (1) each Company employee and each employee
of the Company's Subsidiaries is provided coverage under the Parent
Plans on the same terms and conditions as similarly situated Parent
employees; (2) Parent causes each Parent Plan covering employees of the
Company or its Subsidiaries to recognize prior service of such employees
with the Company and its Subsidiaries as service with Parent and its
Subsidiaries (i) for purposes of any waiting period and eligibility
requirements under any Parent Plan that is not a "pension plan" (as
defined in Section 3(2) of ERISA), and (ii) for purposes of eligibility
(including eligibility for early retirement benefits) and vesting (but
not benefit accrual) under any Parent Plan that is a "pension plan" (as
defined in Section 3(2) of ERISA); (3) Parent causes coverage to be
immediately available for employees of the Company and its Subsidiaries

stockholders of the Company or Parent:

          (a)  by mutual written consent of Parent and the Company;

          (b)  by either Parent or the Company if the other party shall
have failed to comply in any material respect with any of its covenants
or agreements contained in this Agreement required to be complied with
prior to the date of such termination, which failure to comply has not
been cured within thirty business days following receipt by such other
party of written notice from the non-breaching party of such failure to
comply;

          (c)  by either Parent or the Company if there has been (i) a
breach by the other party (in the case of Parent, including any material
breach by Sub) of any representation or warranty that is not qualified
as to materiality which has the effect of making such representation or
warranty not true and correct in all material respects or (ii) a breach
by the other party (in the case of Parent, including any material breach
by Sub) of any representation or warranty that is qualified as to
materiality, in each case which breach has not been cured within thirty
business days following receipt by the breaching party from the
non-breaching party of written notice of the breach;

          (d)  by Parent or the Company if: (i) the Merger has not been
effected on or prior to the close of business on December 31, 1998;
provided, however, that the right to terminate this Agreement pursuant






to this Section 7.1(d)(i) shall not be available to any party whose
failure to fulfill any of its obligations contained in this Agreement
has been the cause of, or resulted in, the failure of the Merger to have
occurred on or prior to the aforesaid date; or (ii) any court or other
Governmental Entity having jurisdiction over a party hereto shall have
issued an order, decree or ruling or taken any other action permanently
enjoining, restraining or otherwise prohibiting the consummation of the

final and nonappealable;

          (e)  by Parent or the Company if the stockholders of the
Company do not approve this Agreement at the Company Stockholder Meeting
or at any adjournment or postponement thereof; provided, however, that
the Company may not terminate this Agreement pursuant to this Section
7.1(e) if the Company has not complied with its obligations under
Sections 4.2, 5.1 and 5.2 or has otherwise breached in any material
respect its obligations under this Agreement in any manner that could
reasonably have caused the failure of the stockholder approval to be
obtained at the Company Stockholder Meeting;

          (f)  by Parent or the Company if the stockholders of Parent do
not approve the Share Issuance at the Parent Stockholder Meeting or at
any adjournment or postponement thereof; provided, however, that Parent
may not terminate this Agreement pursuant to this Section 7.1(f) if
Parent has not complied with its obligations under Sections 5.1 and 5.2
or has otherwise breached in any material respect its obligations under
this Agreement in any manner that could reasonably have caused the
failure of the vote in favor of the Share Issuance to be obtained at the
Parent Stockholder Meeting;

          (g)  by Parent or the Company if (i) the Board of Directors of
the Company reasonably determines that a Takeover Proposal constitutes a
Superior Proposal and (ii) the Board of Directors of the Company
determines in its reasonable good faith judgment, on the basis of the
advice of the outside corporate counsel of the Company, that the failure
to accept such Superior Proposal would violate its fiduciary duties to
its stockholders under applicable law; provided, however, that the
Company may not terminate this Agreement pursuant to this Section 7.1(g)
unless (i) the Company has delivered to Parent a written notice of the
Company's intent to enter into such an agreement to effect the Superior
Proposal, (ii) five business days have elapsed following delivery to
Parent of such written notice by the Company and (iii) during such five
business day period the Company has fully cooperated with Parent,
including, without limitation, informing Parent of the terms and
conditions of the Takeover Proposal and the identity of the person
making the Takeover Proposal, with the intent of enabling Parent to
agree to a modification of the terms and conditions of this Agreement so
that the transactions contemplated hereby, as so modified, may be
effected; provided, further, that the Company may not terminate this
Agreement pursuant to this Section 7.1(g) unless at the end of such five
business day period (i) the Board of Directors of the Company continues
reasonably to believe that the Takeover Proposal constitutes a Superior
Proposal, (ii) the Board of Directors of the Company continues to reach
a determination in its reasonable good faith judgment, on the basis of






the advice of the outside corporate counsel of the Company, that the
failure to accept such Superior Proposal would violate its fiduciary
duties to its stockholders under applicable law and (iii) prior to such
termination the Company pays to Parent the amounts specified under
Sections 5.7(a), (b) and (c); and provided, further, that this Agreement
shall not terminate pursuant to this Section 7.1(g) unless
simultaneously with such termination the Company enters into a
definitive acquisition, merger or similar agreement to effect the
Superior Proposal.

          (h)  by Parent if (i) the Board of Directors of the Company
shall not have recommended, or shall have resolved not to recommend, or
shall have qualified, modified or withdrawn its recommendation of the
Merger or declaration that the Merger is advisable and fair to and in
the best interest of the Company and its stockholders, or shall have
resolved to do so, (ii) any person (other than Parent or its Affiliates)
acquires or becomes the beneficial owner of 20% or more of the
outstanding shares of Company Common Stock, (iii) the Board of Directors
of the Company shall have recommended to the stockholders of the Company
any Takeover Proposal or shall have resolved to do so or (iv) a tender
offer or exchange offer for 20% or more of the outstanding shares of

the Company fails to recommend against acceptance of such tender offer
or exchange offer by its stockholders (including by taking no position
with respect to the acceptance of such tender offer or exchange offer by
its stockholders); or

          (i) by the Company if the Board of Directors of Parent shall
not have recommended, or shall have resolved not to recommend, or shall
have qualified or modified or withdrawn its recommendation of the Share
Issuance or declaration that the Share Issuance is advisable and fair to
and in the best interest of Parent and its stockholders, or shall have
resolved to do so.

          The right of any party hereto to terminate this Agreement
pursuant to this Section 7.1 shall remain operative and in full force
and effect regardless of any investigation made by or on behalf of any
party hereto, any person controlling any such party or any of their
respective officers or directors, whether prior to or after the
execution of this Agreement.

          Section 7.2    Effect of Termination.  In the event of
termination of this Agreement by either Parent or the Company, as
provided in Section 7.1, this Agreement shall forthwith become void and
there shall be no liability hereunder on the part of the Company,
Parent, Sub or their respective officers or directors (except for the
last sentence of Section 5.4 and the entirety of Section 5.7, which
shall survive the termination); provided, however, that nothing
contained in this Section 7.2 shall relieve any party hereto from any
liability for any willful breach of a representation or warranty
contained in this Agreement or the breach of any covenant contained in
this Agreement.








          Section 7.3    Amendment.  This Agreement may be amended by
the parties hereto, by or pursuant to action taken by their respective
Boards of Directors, at any time before or after approval of the matters
presented in connection with the Merger by the stockholders of Parent
and the Company, but, after any such approval, no amendment shall be
made which by law requires further approval by such stockholders without
such further approval.  This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto.

          Section 7.4    Waiver.  At any time prior to the Effective

any of the obligations or other acts of the other parties hereto, (ii)
waive any inaccuracies in the representations and warranties contained

          FORM OF AFFILIATE LETTER FOR AFFILIATES OF THE COMPANY


Tellabs, Inc.   
4951 Indiana Avenue  
Lisle, Illinois 60532

Ladies and Gentlemen:

          I have been advised that as of the date of this letter I may
be deemed to be an "affiliate" of CIENA Corporation, a Delaware
corporation (the "Company"), as the term "affiliate" is (i) defined for
purposes of paragraphs (c) and (d) of Rule 145 of the rules and
regulations (the "Rules and Regulations") of the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Act"), and/or (ii) used in and for purposes of Accounting
Series Releases 130 and 135, as amended, of the Commission.  Pursuant to
the terms of the Agreement and Plan of Merger dated as of June 2, 1998
(the "Merger Agreement") among Tellabs, Inc., a Delaware corporation
("Parent"), White Oak Merger Corp., a Delaware corporation ("Sub"), and
the Company, Sub will be merged with and into the Company (the
"Merger").  Capitalized terms used in this letter without definition
shall have the meanings assigned to them in the Merger Agreement.

          As a result of the Merger, I will receive shares of Common
Stock, no par value, of Parent (the "Parent Shares") in exchange for
shares of common stock, par value $.01 per share, of the Company (the
"Company Shares") owned by me or purchasable upon exercise of stock
options.

     1.  I represent, warrant and covenant to Parent that in the event I
receive any Parent Shares as a result of the Merger:

          A.  I shall not make any sale, transfer or other disposition
of the Parent Shares in violation of the Act or the Rules and
Regulations.

          B.  I have carefully read this letter and the Merger Agreement
and discussed the requirements of such documents and other applicable
limitations upon my ability to sell, transfer or otherwise dispose of
the Parent Shares, to the extent I felt necessary, with my counsel or
counsel for the Company.

          C.  I have been advised that the issuance of the Parent Shares
to me pursuant to the Merger has been or will be registered with the
Commission under the Act on a Registration Statement on Form S-4.
However, I have also been advised that, because at the time the Merger
is submitted for a vote of the stockholders of the Company, (a) I may be
deemed to be an affiliate of the Company and (b) the sale, transfer or
other disposition by me of the Parent Shares will not have been
registered under the Act, I may not sell, transfer or otherwise dispose
of the Parent Shares issued to me in the Merger unless (i) such sale,
transfer or other disposition is made in conformity with the volume and






other limitations of Rule 145 promulgated by the Commission under the
Act, (ii) such sale, transfer or other disposition has been registered
under the Act or (iii) in the opinion of counsel reasonably acceptable
to Parent, such sale, transfer or other disposition is otherwise exempt
from registration under the Act.

          D. I understand that Parent is under no obligation to register
the sale, transfer or other disposition of the Parent Shares by me or on
my behalf under the Act or to take any other action necessary in order
to make compliance with an exemption from such registration available.

          E.  I also understand that there will be placed on the
certificates for the Parent Shares issued to me, or any substitutions
therefor, a legend stating in substance:


     "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A 
     TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT
     OF 1933 APPLIES.  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY
     ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT
     BETWEEN THE REGISTERED HOLDER HEREOF AND TELLABS, INC., A COPY OF
     WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF TELLABS,
     INC."


          F.  I also understand that unless a sale or transfer is made
in conformity with the provisions of Rule 145, or pursuant to a
registration statement, Parent reserves the right to put the following
legend on the certificates issued to my transferee:


     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM
     A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE
     145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES.  THE
     SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR
     RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE
     MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED
     OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION
     FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933."


          G.  I further represent to, and covenant with, Parent that I
will not, during the 30 days prior to the Effective Time (as defined in
the Merger Agreement), sell, transfer or otherwise dispose of or reduce
my risk (as contemplated by SEC Accounting Series Release No.  135) with
respect to the Company Shares or shares of the capital stock of Parent
that I may hold and, furthermore, that I will not sell, transfer or
otherwise dispose of or reduce my risk (as contemplated by SEC
Accounting Series Release No.  135) with respect to the Parent Shares
received by me in the Merger or any other shares of the capital stock of
Parent until after such time as results covering at least 30 days of
combined operations of the Company and Parent have been published by
Parent, in the form of a quarterly earnings report, an effective






registration statement filed with the Commission, a report to the
Commission on Form 10-K, 10-Q, or 8-K, or any other public filing or
announcement which includes the combined results of operations.
Notwithstanding the foregoing provisions of this paragraph 1(G), but
subject to the other provisions of this letter, I understand that during
the aforementioned period, subject to providing written notice to and
obtaining the consent of Parent, which consent shall not be unreasonably
withheld, I will not be prohibited from de minimis dispositions and
charitable contributions or bona fide gifts of the Parent Shares which,
in each case, will not disqualify the accounting for the Merger as a
pooling of interests.

          H.  Execution of this letter should not be considered an
admission on my part that I am an "affiliate" of the Company as
described in the first paragraph of this letter, nor as a waiver of any
rights I may have to object to any claim that I am such an affiliate on
or after the date of this letter.

     2.  By Parent's acceptance of this letter, Parent hereby agrees
with me that certificates with the legends set forth in paragraphs 1(E)
and (F) above will be substituted by delivery of certificates without
such legend if (i) one year shall have elapsed from the date the
undersigned acquired the Parent Shares received in the Merger and the
provisions of Rule 145(d)(2) are then available to the undersigned, (ii)
two years shall have elapsed from the date the undersigned acquired the
Parent Shares received in the Merger and the provisions of Rule
145(d)(3) are then applicable to the undersigned, or (iii) the Parent
has received an opinion of counsel, which opinion and counsel shall be
reasonably satisfactory to Parent to the effect that the restrictions
imposed by Rule 145 under the Act no longer apply to the undersigned.


                                   Very truly yours,


                                   ______________________________

          FORM OF AFFILIATE LETTER FOR AFFILIATES OF PARENT


Tellabs, Inc.   
4951 Indiana Avenue  
Lisle, Illinois 60532

Ladies and Gentlemen:

          I have been advised that as of the date of this letter I may
be deemed to be an "affiliate" of Tellabs, Inc., a Delaware corporation
("Parent"), as the term "affiliate" is defined for purposes of
Accounting Series Releases 130 and 135, as amended, of the Securities
and Exchange Commission ("Commission").  Pursuant to the terms of the
Agreement and Plan of Merger dated as of June 2, 1998 (the "Merger
Agreement") among Parent, White Oak Merger Corp., a Delaware corporation
("Sub"), and CIENA Corporation, a Delaware corporation (the "Company"),
Sub will be merged with and into the Company (the "Merger").

          I represent to, and covenant with, Parent that I will not,
during the period beginning 30 days prior to the Effective Time (as
defined in the Merger Agreement) until after such time as results
covering at least 30 days of combined operations of the Company and
Parent have been published by Parent, in the form of a quarterly
earnings report, an effective registration statement filed with the
Commission, a report to the Commission on Form 10-K, 10-Q, or 8-K, or
any other public filing or announcement which includes the combined
results of operations, sell, transfer or otherwise dispose of or reduce
my risk with respect to any shares of the capital stock of Parent
("Parent Stock") or the Company that I may hold.  Notwithstanding the
foregoing, I understand that during the aforementioned period, subject
to providing written notice to and obtaining the consent of Parent,
which consent shall not be unreasonably withheld, I will not be
prohibited from de minimis dispositions and charitable contributions or
bona fide gifts of the Parent Stock which, in each case, will not
disqualify the accounting for the Merger as a pooling of interests.

          Execution of this letter should not be considered an admission
on my part that I am an "affiliate" of Parent as described in the first
paragraph of this letter, nor as a waiver of any rights I may have to
object to any claim that I am such an affiliate on or after the date of
this letter.


                                   Very truly yours,

                                   ______________________________

                                                       Exhibit 2.3 


                         STOCK OPTION AGREEMENT


          STOCK OPTION AGREEMENT, dated as of June 2, 1998 (the
"Agreement"), between Tellabs, Inc., a Delaware corporation ("Parent"),
and CIENA Corporation, a Delaware corporation (the "Company").


                         W I T N E S S E T H:

          WHEREAS, simultaneously with the execution and delivery of
this Agreement, Parent, White Oak Merger Corp., a newly formed Delaware
corporation and a direct wholly owned subsidiary of Parent ("Sub"), and
the Company are entering into an Agreement and Plan of Merger, dated as
of the date hereof (the "Merger Agreement"), which provides for the
merger of Sub with and into the Company;

          WHEREAS, as a condition to Parent's willingness to enter into
the Merger Agreement, Parent has requested that the Company grant to
Parent an option to purchase up to 20,200,000 authorized and unissued
shares of Company Common Stock, upon the terms and subject to the
conditions hereof; and

          WHEREAS, in order to induce Parent to enter into the Merger
Agreement, the Company has agreed to grant Parent the requested option.

          NOW, THEREFORE, in consideration of the premises and the
mutual covenants and agreements set forth herein, the parties hereto
agree as follows:

          1.   The Option; Exercise; Adjustments.  The Company hereby
grants to Parent an irrevocable option (the "Option") to purchase from
time to time up to 20,200,000 authorized and unissued shares of common
stock, par value $.01 per share, of the Company (the "Company Common
Stock"), upon the terms and subject to the conditions set forth herein
(the "Optioned Shares").  Subject to the conditions set forth in Section
2(a), the Option may be exercised by Parent in whole or from time to
time in part, at any time after the date hereof and prior to the
termination of the Option in accordance with Section 19.  In the event
Parent wishes to exercise the Option, Parent shall send a written notice
to the Company (the "Stock Exercise Notice") specifying the total number
of Optioned Shares it wishes to purchase and a date (not later than 20
business days and not earlier than two business days from the date such
notice is given) for the closing of such purchase (the "Closing Date").
Parent may revoke an exercise of the Option at any time prior to the
Closing Date by written notice to the Company.  In the event of any
change in Company Common Stock by reason of any stock dividend, stock
split, split-up, recapitalization, merger or other change in the
corporate or capital structure of the Company, the number and type of
Optioned Shares subject to the Option and the Exercise Price (as
hereinafter defined) per Optioned Share shall be appropriately adjusted.






In the event that any additional shares of Company Common Stock are
issued after the date of this Agreement (other than pursuant to an event
described in the preceding sentence or pursuant to this Agreement), the
number of Optioned Shares subject to the Option shall be adjusted so
that, after such issuance, it equals (but does not exceed) 19.9% of the
number of shares of Company Common Stock then issued and outstanding and
19.9% of the voting power of shares of capital stock of the Company then
issued and outstanding, after reduction, to the extent necessary to
comply with the exception to the shareholder approval requirements of
NASDAQ (as hereinafter defined), for any shares issued pursuant to the
Option.

          2.   Conditions to Exercise of Option and Delivery of Optioned
Shares.  (a) Parent's right to exercise the Option is subject to the
following conditions:

          (i)  Neither Parent nor Sub shall have breached any of its
material obligations under the Merger Agreement;

          (ii) No preliminary or permanent injunction or other order
issued by any federal or state court of competent jurisdiction in the
United States invalidating the grant or prohibiting the exercise of the
Option shall be in effect;

          (iii) A Third Party Acquisition Event shall have occurred or
the Company shall have entered into a letter of intent, agreement in
principle, acquisition agreement or other similar agreement with respect
to a Third Party Acquisition Event; and

          (iv) This Agreement and the Option shall not have terminated
pursuant to Section 19 hereof.

          (b) Parent's obligation to purchase the Optioned Shares
following the exercise of the Option, and the Company's obligation to
deliver the Optioned Shares, are subject to the following conditions:

          (i)  No preliminary or permanent injunction or other order
issued by any federal or state court of competent jurisdiction in the
United States prohibiting the delivery of the Optioned Shares shall be
in effect;

          (ii) The purchase of the Optioned Shares will not violate Rule
10b-13 promulgated under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"); and

          (iii)     All applicable waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
"HSR Act"), shall have expired or been terminated.

          3.   Exercise Price for Optioned Shares.  At any Closing Date,
the Company will deliver to Parent a certificate or certificates
representing the Optioned Shares in the denominations designated by
Parent in its Stock Exercise Notice and Parent will purchase the
Optioned Shares from the Company at a price per Optioned Share equal to






$65.875 (the "Exercise Price"), payable in common stock, par value $.01
per share, of Parent (the "Parent Common Stock"), cash or a combination
of Parent Common Stock or cash, in each case at Parent's option, as
specified in the Stock Exercise Notice.  Any cash payment made by Parent
to the Company pursuant to this Agreement shall be made by wire transfer
of federal funds to a bank designated by the Company or a check payable
in immediately available funds.  If Parent elects to pay the Exercise
Price or a portion thereof in Parent Common Stock, the Parent Common
Stock shall be valued at the average of the last reported sales prices
of the Parent Common Stock on The Nasdaq Stock Market ("NASDAQ") for the
five trading days immediately prior to the date of the Stock Exercise
Notice.  After payment of the Exercise Price for the Optioned Shares
covered by the Stock Exercise Notice, the Option shall be deemed
exercised to the extent of the Optioned Shares specified in the Stock
Exercise Notice as of the date such Stock Exercise Notice is given to
the Company.  Notwithstanding anything to the contrary herein, the
Exercise Price shall from time to time be adjusted so that in no event
shall the Aggregate Spread Value, together with the Termination Fee,
exceed $200,000,000 (it being understood that, if the Exercise Price has
been increased from time to time as a result of this sentence, the
Exercise Price shall from time to time be adjusted downward to the
extent of any decrease in the price of the Company Common Stock).
"Spread Value" with respect to an Optioned Share means the excess, if
any, of (i) the average of the last reported sales prices on NASDAQ of
the Company Common Stock during the five trading days immediately
preceding the written notice of exercise (in the case of an Optioned
Share previously exercised) or the date of determination (in the case of
an Optioned Share as to which the Option has not yet been exercised)
over (ii) the Exercise Price.  The Aggregate Spread Value shall be the
sum of the Spread Values of all Optioned Shares.

          4.   Representations and Warranties of the Company.  The
Company represents and warrants to Parent that (a) the execution and
delivery of this Agreement by the Company and the consummation by it of
the transactions contemplated hereby have been duly authorized by all
necessary corporate action on the part of the Company and this Agreement
has been duly executed and delivered by the Company and constitutes a
valid and binding obligation of the Company enforceable against the
Company in accordance with its terms; (b) the Company has taken all
necessary corporate action to authorize and reserve the Optioned Shares
for issuance upon exercise of the Option, and the Optioned Shares, when
issued and delivered by the Company to Parent upon exercise of the
Option, will be duly authorized, validly issued, fully paid and
nonassessable and free of preemptive rights; (c) except as otherwise
required by the HSR Act, except for routine filings and subject to
Section 7, the execution and delivery of this Agreement by the Company
and the consummation by it of the transactions contemplated hereby do
not require the consent, approval or authorization of, or filing with,
any person or public authority and will not violate or conflict with the
Company's Third Restated Certificate of Incorporation, as amended, or
Amended and Restated By-Laws, or result in the acceleration or
termination of, or constitute a default under, any indenture, license,
approval, agreement, understanding or other instrument, or any statute,
rule, regulation, judgment, order or other restriction binding upon or






applicable to the Company or any of its subsidiaries or any of their
respective properties or assets; (d) the Company is a corporation duly
organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite corporate power and authority to
execute and deliver this Agreement and to consummate the transactions
contemplated hereby; and (e) the Company has taken all appropriate
actions so that the restrictions on business combinations contained in
Section 203 of the General Corporation Law of the State of Delaware, as
amended, will not apply with respect to or as a result of the
transactions contemplated hereby.

          5.   Representations and Warranties of Parent.  Parent
represents and warrants to the Company that (a) the execution and
delivery of this Agreement by Parent and the consummation by it of the
transactions contemplated hereby have been duly authorized by all
necessary corporate action on the part of Parent and this Agreement has
been duly executed and delivered by Parent and constitutes a valid and
binding agreement of Parent; and (b) Parent is acquiring the Option and,
if and when it exercises the Option, will be acquiring the Optioned
Shares issuable upon the exercise thereof for its own account and not
with a view to distribution or resale in any manner which would be in
violation of the Securities Act of 1933, as amended (the "Securities
Act"), and will not sell or otherwise dispose of the Optioned Shares
except pursuant to an effective registration statement under the
Securities Act or a valid exemption from registration under the
Securities Act.

          6.   The Closing.  Any closing hereunder shall take place on
the Closing Date specified by Parent in its Stock Exercise Notice
pursuant to Section 1 at 10:00 A.M., local time, or the first business
day thereafter on which all of the conditions in Section 2(b) are met,
at the principal executive office of the Company, or at such other time
and place as the parties hereto may agree.

          7.   Filings Related to Optioned Shares.  The Company will
make such filings with the Securities and Exchange Commission and the
National Association of Securities Dealers, Inc. as are required by the
Exchange Act in connection with the execution and delivery of this
Agreement and the exercise of the Option, and will use its best efforts
to effect all necessary filings by the Company under the HSR Act and to
have the Optioned Shares approved for quotation on NASDAQ.

          8.   Registration Rights.  (a)  If the Company effects any
registration or registrations of shares of Company Common Stock under
the Securities Act for its own account or for any other stockholder of
the Company at any time after the exercise of the Option (other than a
registration on Form S-4, Form S-8 or any successor forms), it will
allow Parent to participate in such registration or registrations with
respect to any or all of the Optioned Shares acquired upon the exercise
of the Option, subject to any existing priority registration rights
granted to existing holders of Company Common Stock; provided, however,
that if the managing underwriters in such offering advise the Company
that, in their written opinion, the number of Optioned Shares requested
by Parent to be included in such registration exceeds the number of






shares of Company Common Stock which can be sold in such offering, the
Company may exclude from such registration all or a portion, as may be
appropriate, of the Optioned Shares requested for inclusion by Parent.

          (b)  At any time after the exercise of the Option, upon the
request of Parent, the Company will promptly file and use its best
efforts to cause to be declared effective a registration statement under
the Securities Act (and applicable Blue Sky statutes) with respect to
any or all of the Optioned Shares acquired upon the exercise of the
Option; provided, however, that the Company shall not be required to
have declared effective more than three registration statements
hereunder and shall be entitled to delay the effectiveness of each such
registration statement, for a period not to exceed 90 days in the
aggregate, if the commencement of such offering would, in the reasonable
good faith judgment of the Board of Directors of the Company, require
premature disclosure of any material corporate development or otherwise
materially interfere with or materially adversely affect any pending or
proposed offering of securities of the Company.  In connection with any
such registration requested by Parent, the costs of such registration
shall be borne by the Company; provided, however, that if Parent is
eligible to sell the Optioned Shares under Rule 144(k) of the Securities
Act, Parent shall pay the costs of such registration.  The Company and
Parent each shall provide the other and any underwriters with customary
indemnification and contribution agreements.

          9.   Optional Put.  Prior to the termination of the Option  
in accordance with Section 19, if any event set forth in Section
2(a)(iii) has occurred and the other conditions set forth in Section
2(a) are met, Parent shall have the right, upon three business days'
prior written notice to the Company, to require the Company to purchase
the Option from Parent (the "Put Right") at a cash purchase price (the
"Put Price") equal to the product determined by multiplying (A) the
number of Optioned Shares as to which the Option has not yet been
exercised by (B) the Spread (as defined below).  As used herein, the
term "Spread" shall mean the excess, if any, of (i) the greater of (x)
the highest price (in cash or fair market value of securities or other
property) per share of Company Common Stock paid or to be paid within 12
months preceding the date of exercise of the Put Right for any shares of
Company Common Stock beneficially owned by any Person who shall have
acquired or become the beneficial owner of 20% or more of the
outstanding shares of Company Common Stock after the date hereof or (y)
the average of the last reported sales prices on NASDAQ of the Company
Common Stock during the five trading days immediately preceding the
written notice of exercise of the Put Right over (ii) the Exercise
Price.  Notwithstanding anything herein to the contrary, in no event
shall the aggregate Put Price, together with the Aggregate Spread Value
of any Optioned Shares previously exercised and the amount of the
Termination Fee then payable or previously paid, exceed $200,000,000.

          10.  Expenses.  Each party hereto shall pay its own expenses
incurred in connection with this Agreement, except as otherwise provided
in Section 8 or as specified in the Merger Agreement.








          11.  Specific Performance.  The parties hereto agree that
irreparable damage would occur 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 shall be entitled to an injunction or injunctions to prevent
breaches of this Agreement and to enforce specifically the terms and
provisions hereof in any court of the United States or any state thereof
having jurisdiction, this being in addition to any other remedy to which
they are entitled at law or in equity.

          12.  Notice.  All notices, requests, demands and other
communications hereunder shall be deemed to have been duly given and
made if in writing and if served by personal delivery upon the party for

                    TELLABS AND CIENA AGREE TO MERGE


        Combination Expected to Accelerate Pace of Evolution and  
                Speed of Revolution in the Public Network

Lisle, Ill., -- Tellabs, Inc., and CIENA Corporation today announced an
agreement to merge the two companies to create a next-generation network
equipment provider.

Under the terms of the agreement, all outstanding shares of CIENA stock
will be exchanged at the ratio of one share of Tellabs common stock for
each share of CIENA common stock.  Based on the closing price of Tellabs
common stock on June 2, 1998, the transaction is valued at approximately
$7.1 billion.  Excluding expected one-time transaction costs, the
company expects slight earnings-per-share dilution in 1998 and no
dilution in 1999 assuming expected synergies.  The combined company will
retain the Tellabs name.

"As competition among service providers continues to heighten, equipment
suppliers must help both incumbent and newly established carriers meet
the demands for increasing and effectively managing bandwidth in their
networks," said Tellabs President and CEO Michael J. Birck.  "CIENA's
expertise in dense wavelength division multiplexing is a perfect fit
with Tellabs' SONET/SDH managed transport capabilities.  The combined
company will be well positioned to enhance the ability of both
established carriers and new service entrants everywhere to build
advanced, high-speed networks."









"Separately, these two companies are `best of breed' in the
telecommunications industry," said CIENA President and CEO Patrick
Nettles.  "Together we expect to be able to leverage Tellabs'
established position with telecom service providers and CIENA's
leadership in optical transport solutions to lower the cost of bandwidth
and simplify network management.  We expect the new combined company to
accelerate the pace of evolution and speed of revolution in the public
networks."

Following the merger, Birck will serve as chairman and chief executive
officer of the combined company, while Nettles will become its president
and chief operating officer.  Upon closing, the combined company will be
headquartered in Lisle, Ill.  CIENA's facilities in Linthicum, Md., and
Savage, Md., together with Tellabs' existing optical networking group in
Hawthorne, N.Y., and Burlington, Mass., will form the core of the
combined company's optical networking efforts.

The transaction is expected to be accounted for as a
pooling-of-interests, to qualify as a tax-free reorganization, and to
close during Tellabs' third quarter.  Upon closing, CIENA will become a
subsidiary of Tellabs.  This transaction is subject to various
conditions and approval by appropriate government agencies and the
stockholders of Tellabs and CIENA.  The Board of Directors of each
company unanimously approved the transaction and recommended its
approval by the stockholders.

Goldman Sachs acted as financial advisor to Tellabs for this
transaction, while Morgan Stanley represented CIENA.

CIENA (NASDAQ: CIEN) is a market leader of open architecture, dense
wavelength division multiplexing systems for long-distance and local
exchange carriers.  Through its Alta subsidiary CIENA also provides a
range of engineering, furnishing and installation (EF&I) services for
telecommunications service providers in the areas of transport,
switching and wireless communications.

Tellabs designs, manufactures, markets and services voice and data
transport and access systems.  The company's products are used worldwide
by the providers of communications services.  Tellabs, Inc., stock is
listed on the Nasdaq Stock Market (TLAB).

This news release contains forward-looking statements that involve risks
and uncertainties.  Actual results, including the level of earnings of
both Tellabs and CIENA Corporation, and the success of the proposed
merger may differ from the results discussed in the forward-looking
statements.  Factors that might cause such a difference include, but are
not limited to, risks associated with acquisitions, such as difficulties
in the assimilation of operations, technologies and products of the
acquired companies, diversion of management's attention from other
business concerns, risks of entering new markets, competitive response,
and a downturn in the telecommunications industry.  For a more detailed
description of the risk factors associated with Tellabs and CIENA
Corporation, please refer to the companies' respective SEC filings.
