                     PRELIMINARY COPY-SUBJECT TO COMPLETION


                             EXCEL TECHNOLOGY, INC.
                                 41 RESEARCH WAY
                            EAST SETAUKET, N.Y. 11733

March    , 2006

Dear Excel Technology, Inc. Stockholder:

         You are cordially invited to attend a special meeting of the
stockholders of Excel Technology, Inc. to be held on March __, 2006, at 10:00
a.m. local time, at 41 Research Way, E. Setauket, N.Y. 11733.

         At the special meeting, you will be asked to consider and vote upon a
proposal to adopt an Agreement and Plan of Merger, dated as of February 20,
2006, among Coherent, Inc., Spider Acquisition Corporation (a wholly owned
subsidiary of Coherent) and Excel Technology, Inc. Pursuant to the Agreement and
Plan of Merger, Spider Acquisition Corporation will merge with and into Excel
Technology, with Excel Technology surviving the merger and becoming a wholly
owned subsidiary of Coherent. For your reference, a copy of the merger agreement
is attached to the enclosed proxy statement as Annex A. We encourage you to read
the accompanying proxy statement, which provides you with detailed information
about the special meeting and the merger.

         If the merger agreement is adopted by our stockholders and the merger
is completed, all outstanding shares of Excel Technology common stock will be
cancelled and you will receive $30.00 in cash for each share of our common stock
that you own at the effective time of the merger (except for shares held by
stockholders who have perfected their dissenters' rights of appraisal under
Delaware law). The cash you receive in the merger in exchange for your shares of
Excel Technology common stock will be subject to U.S. federal income tax and
also may be taxed under applicable state, local and foreign tax laws.

         AFTER CAREFUL CONSIDERATION, THE EXCEL TECHNOLOGY BOARD OF DIRECTORS
HAS UNANIMOUSLY DETERMINED THAT THE MERGER AGREEMENT AND THE MERGER ARE
ADVISABLE AND IN THE BEST INTERESTS OF EXCEL TECHNOLOGY AND ITS STOCKHOLDERS.
OUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT. OUR BOARD
OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE ADOPTION OF THE
MERGER AGREEMENT. IN REACHING ITS DETERMINATION, THE EXCEL TECHNOLOGY BOARD OF
DIRECTORS CONSIDERED A NUMBER OF FACTORS DESCRIBED MORE FULLY IN THE
ACCOMPANYING PROXY STATEMENT.

         Because the adoption of the merger agreement requires the affirmative
vote of the holders of a majority of the outstanding shares of Excel Technology
common stock entitled to vote at the meeting, a failure to vote will have the
same effect as a vote "against" the merger. Only stockholders who owned shares
of Excel Technology common stock at the close of business on March 6, 2006, the
record date for the special meeting, will be entitled to vote at the special
meeting.

         YOUR VOTE IS VERY IMPORTANT. WHETHER OR NOT YOU PLAN TO ATTEND THE
MEETING, PLEASE COMPLETE, SIGN, DATE AND MAIL PROMPTLY THE ACCOMPANYING PROXY
CARD IN THE ENCLOSED RETURN ENVELOPE, WHICH REQUIRES NO POSTAGE IF MAILED IN THE
UNITED STATES, OR VOTE USING THE TELEPHONE OR INTERNET USING THE INSTRUCTIONS ON
THE PROXY CARD. THIS WILL ENSURE THE PRESENCE OF A QUORUM AT THE MEETING. IF YOU
ATTEND THE MEETING, YOU MAY VOTE IN PERSON IF YOU WISH TO DO SO EVEN IF YOU HAVE
PREVIOUSLY SENT IN YOUR PROXY CARD OR VOTED BY TELEPHONE OR INTERNET.

         Thank you for your cooperation and continued support.

                                           Very truly yours,

                                           Antoine Dominic
                                           PRESIDENT AND CHIEF EXECUTIVE OFFICER

         THE PROXY STATEMENT IS DATED MARCH ___, 2006, AND IS FIRST BEING MAILED
TO STOCKHOLDERS ON OR ABOUT MARCH ___, 2006.

                    NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

To our Stockholders:

         A special meeting of the stockholders of Excel Technology, Inc., a
Delaware corporation, will be held on March ___, 2006, at 10:00 a.m. local time,
at the offices of Excel Technology, Inc. 41 Research Way, East Setauket, NY
11733, for the following purposes:

         1. To adopt an Agreement and Plan of Merger, dated as of February 20,
2006, by and among Coherent, Inc., Spider Acquisition Corporation (a wholly
owned subsidiary of Coherent), and Excel Technology, Inc.;

         2. To grant the persons named as proxies discretionary authority to
vote to adjourn or postpone the special meeting, if necessary, to solicit
additional proxies if there are not sufficient votes for the adoption of the
Agreement and Plan of Merger at the time of the special meeting; and

         3. To transact such other business as may properly come before the
special meeting or any adjournment or postponement of the special meeting.

         These proposals are more fully described in the accompanying proxy
statement, and we have included a copy of the Agreement and Plan of Merger
(which we refer to herein as the "merger agreement") as Annex A to this proxy
statement.

         Only stockholders of record at the close of business on March 6, 2006
will be entitled to notice of, and to vote at, such special meeting or any
adjournments or postponements of the special meeting. The adoption of the merger
agreement requires the approval of the holders of a majority of Excel Technology
common stock outstanding at the close of business on the record date.

         THE BOARD OF DIRECTORS OF EXCEL TECHNOLOGY HAS UNANIMOUSLY DETERMINED
THAT THE MERGER AGREEMENT AND THE MERGER ARE ADVISABLE AND IN THE BEST INTERESTS
OF EXCEL TECHNOLOGY AND ITS STOCKHOLDERS AND HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT. OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR"
ADOPTION OF THE MERGER AGREEMENT. The board of directors of Excel Technology
also recommends that you expressly grant the authority to the persons named as
proxies to vote your shares to adjourn or postpone the special meeting, if
necessary, to permit the further solicitation of proxies if there are not
sufficient votes at the time of the special meeting to adopt the merger
agreement. We are not aware of any other business to come before the special
meeting.

         Under Delaware law, stockholders have the right to dissent from the
merger and obtain payment in cash of the fair value of their Excel Technology
common stock. In order to perfect and exercise appraisal rights, stockholders
must give written demand for appraisal of their shares before the taking of the
vote at the special meeting and must not vote to adopt the merger agreement. A
copy of the applicable Delaware statutory provisions is included as Annex C to
the accompanying proxy statement, and a summary of these provisions can be found
under Dissenters' Rights of Appraisal" on page 37 in the accompanying proxy
statement.

                                           BY ORDER OF THE BOARD OF DIRECTORS

                           FORWARD-LOOKING INFORMATION

         This proxy statement contains "forward-looking statements," as defined
in Section 27A of the Securities Act of 1933, as amended, and Section 2E of the
Securities Exchange Act of 1934, as amended, that are based on our current
expectations, assumptions, beliefs, estimates and projections about our company
and our industry. These forward-looking statements include, among other things,
statements concerning whether and when the proposed merger will close, whether
conditions to the proposed merger will be satisfied, the effect of the proposed
merger on our business and operating results and other statements that can be
identified by the use of forward-looking terminology such as "anticipate,"
"believe," "estimate," "expect," "intend," "project," "should" and similar
expressions. The forward-looking statements are subject to various risks and
uncertainties that could cause actual results to differ materially from those
described in the forward-looking statements. Factors that may affect those
forward-looking statements include, among other things:

         o        the failure of the merger to be consummated in a timely manner
                  if at all,

         o        the requirement that our stockholders adopt the merger
                  agreement,

         o        receipt of necessary approval under applicable antitrust laws,
                  and

         o        failure by us to satisfy other conditions to the merger.

         We caution you that reliance on any forward-looking statement involves
risks and uncertainties, and that although we believe that the assumptions on
which our forward-looking statements are based are reasonable, any of these
assumptions could prove to be inaccurate, and, as a result, the forward-looking
statements based on those assumptions could be incorrect. In light of these and
other uncertainties, you should not conclude that we will necessarily achieve
any plans and objectives or projected financial results referred to in any of
the forward-looking statements. We do not undertake to release the results of
any revisions of these forward-looking statements to reflect future events or
circumstances.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

         THE FOLLOWING QUESTIONS AND ANSWERS ARE INTENDED TO ADDRESS SOME
COMMONLY ASKED QUESTIONS ABOUT THE MERGER. THESE QUESTIONS AND ANSWERS MAY NOT
ADDRESS ALL QUESTIONS THAT MAY BE IMPORTANT TO YOU AS AN EXCEL TECHNOLOGY
STOCKHOLDER. WE URGE YOU TO READ CAREFULLY THE MORE DETAILED INFORMATION
CONTAINED ELSEWHERE IN THIS PROXY STATEMENT AND THE ANNEXES TO THIS PROXY
STATEMENT.

Q:       WHY AM I RECEIVING THIS PROXY STATEMENT?

A:       Our board of directors is furnishing this proxy statement in connection
         with the solicitation of proxies to be voted at a special meeting of
         stockholders, or at any adjournments, postponements or continuations of
         the special meeting.

Q:       WHAT AM I BEING ASKED TO VOTE ON?

A:       You are being asked to vote to adopt a merger agreement that provides
         for the acquisition of Excel Technology by Coherent. The acquisition
         would be accomplished through a merger of Spider Acquisition
         Corporation, a wholly owned subsidiary of Coherent (which we refer to
         as "Merger Sub"), with and into Excel Technology. As a result of the
         merger, Excel Technology will become a wholly owned subsidiary of
         Coherent, and Excel Technology common stock will cease to be listed on
         the NASDAQ Stock Market, will not be publicly traded and will be
         deregistered under the Securities Exchange Act of 1934, as amended.

         In addition, you are being asked to grant Excel Technology management
         discretionary authority to adjourn or postpone the special meeting. If,
         for example, we do not receive proxies from stockholders holding a
         sufficient number of shares to approve the proposed transaction, we
         could use the additional time to solicit additional proxies in favor of
         approval of the merger agreement.

Q:       WHAT VOTE IS REQUIRED BY OUR STOCKHOLDERS TO ADOPT THE MERGER
         AGREEMENT?

A:       In order for the merger to be approved, holders of a majority of our
         outstanding common stock must vote "FOR" adoption of the merger
         agreement. Executed proxies returned to us but not marked to indicate
         your voting preference will be counted as votes "FOR" adoption of the
         merger agreement.

Q:       HOW DOES OUR BOARD RECOMMEND THAT I VOTE?

A:       At a meeting held on February 17, 2006, our board of directors
         determined that the merger agreement and the merger are advisable and
         in the bests interests of Excel Technology and its stockholders and
         unanimously approved the merger agreement. OUR BOARD OF DIRECTORS
         UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE ADOPTION OF THE MERGER
         AGREEMENT AND "FOR" THE PROPOSAL TO ADJOURN OR POSTPONE THE SPECIAL
         MEETING, IF NECESSARY OR APPROPRIATE, TO SOLICIT ADDITIONAL PROXIES IN
         THE EVENT THERE ARE NOT SUFFICIENT VOTES FOR ADOPTION OF THE MERGER
         AGREEMENT AT THE TIME OF THE SPECIAL MEETING.

Q:       WHAT FACTORS DID THE EXCEL TECHNOLOGY'S BOARD OF DIRECTORS CONSIDER IN
         MAKING ITS RECOMMENDATION?

A:       In making its recommendation, our board of directors took into account,
         among other things, the $30.00 per share cash consideration to be
         received by holders of our common stock in the merger in relation to
         the uncertainties and market risks of building future value of Excel
         Technology as an independent entity in what we believe will be a
         consolidating industry, the terms and conditions of the merger
         agreement, including our ability to furnish information to, and conduct
         negotiations with, a third party should we receive a superior offer,
         and the process through which we, with the assistance of our financial
         advisors, engaged, or sought to engage, in discussions with entities
         believed to be the most likely candidates to pursue a business
         combination with or acquire us, and the fact that no strategic or
         financial buyer other than Coherent made a written proposal to acquire
         us.

                                      vii


Q:       WHAT WILL I RECEIVE IN THE MERGER?

A:       Upon completion of the merger, you will receive $30.00 in cash for each
         share of our common stock that you own (except to the extent you
         properly exercise your appraisal rights under Delaware law - see page
         37 of this proxy statement). After the merger closes, Coherent will
         arrange for a letter of transmittal to be sent to each of our
         stockholders. The merger consideration will be paid to each stockholder
         once that stockholder submits a completed letter of transmittal,
         properly endorsed stock certificates and any other required
         documentation.

Q:       WHAT DO I NEED TO DO NOW?

A:       After carefully reading this proxy statement, including its annexes, we
         urge you to respond by voting your shares through one of the following
         means.

         o   BY MAIL, by completing, signing, dating and mailing each proxy card
         or voting instruction card and returning it in the envelope provided;

         o   VIA TELEPHONE, using the toll-free number listed on each proxy card
         (if you are a registered stockholder, meaning that you hold your stock
         in your name) or voting instruction card (if your shares are held in
         "street name," meaning that your shares are held in the name of a
         broker, bank or other nominee, and your bank, broker or nominee makes
         telephone voting available);

         o   VIA THE INTERNET, at the address provided on each proxy card (if
         you are a registered stockholder) or voting instruction card (if your
         shares are held in "street name" and your bank, broker or nominee makes
         Internet voting available); or

         o   IN PERSON, by attending the special meeting and submitting your
         vote in person.

Q.       IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER
         VOTE MY SHARES FOR ME?

A.       Yes, but only if you provide instructions to your broker on how to
         vote. You should follow the directions provided by your broker
         regarding how to instruct your broker to vote your shares. Without
         those instructions, your shares will not be voted, which will have the
         same effect as voting against adoption of the merger agreement.

Q:       WHAT IF I DON'T VOTE?

A:       If you fail to vote, it will have the same effect as a vote against
         adoption of the merger agreement. If you submit your executed proxy but
         fail to indicate how you want to vote on the merger, your proxy will be
         counted as a vote in favor of adoption of the merger agreement. If you
         submit your proxy and indicate that you are abstaining from voting,
         your proxy will have the same effect as a vote against adoption of the
         merger agreement.

Q:       CAN I CHANGE MY VOTE AFTER I HAVE SUBMITTED MY PROXY?

A.       Yes. You can change your vote at any time before your proxy is voted at
         the special meeting. If you are a registered stockholder, you may
         revoke your proxy by notifying our Secretary in writing or by
         submitting a new proxy by mail, telephone or the Internet, in each
         case, dated after the date of the proxy being revoked. In addition,
         your proxy may be revoked by attending the special meeting and voting
         in person (you must vote in person, simply attending the special
         meeting will not cause your proxy to be revoked). If you hold your
         shares in "street name" and you have instructed a broker to vote your
         shares, these options for changing your vote do not apply, and you must
         instead follow the instructions received from your broker to change
         your vote.

                                      viii


Q:       WHAT DOES IT MEAN IF I GET MORE THAN ONE PROXY CARD OR VOTING
         INSTRUCTION CARD?

A:       If your shares are registered differently and are in more than one
         account, you will receive more than one card. Please complete and
         return all of the proxy cards and voting instruction cards you receive
         (or submit your proxy by telephone or the Internet, if available to
         you) to ensure that all of your shares are voted.

Q:       WHAT HAPPENS IF I SELL MY SHARES OF EXCEL TECHNOLOGY COMMON STOCK
         BEFORE THE SPECIAL MEETING?

A:       The record date for the special meeting is earlier than the date of the
         special meeting and the date the merger is expected to be completed. If
         you transfer your shares of Excel Technology common stock after the
         record date but before the special meeting, you will retain your right
         to vote at the special meeting, but will transfer the right to receive
         the merger consideration.

Q:       WILL I OWE TAXES AS A RESULT OF THE MERGER?

A:       If you are a U.S. holder, for U.S. federal income tax purposes, the
         exchange of your shares of Excel Technology common stock for cash
         pursuant to the merger will be treated as a taxable exchange by you.
         Accordingly, you will recognize a gain or loss equal to the difference
         between the amount of cash you receive and your adjusted tax basis in
         your shares of Excel Technology common stock for U.S. federal income
         tax purposes. If you are a non-U.S. holder of Excel Technology common
         stock, the merger will generally not be a taxable transaction to you
         under U.S. federal income tax laws unless you have certain connections
         to the United States. We recommend that you read the section entitled
         "Material U.S. Federal Income Tax Consequences" in this proxy statement
         on page 23 for a more detailed explanation of the tax consequences of
         the merger. You are urged to consult your tax advisor regarding the
         specific tax consequences of the merger applicable to you in light of
         your particular circumstances.

Q:       SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A:       No. If the merger agreement is adopted by our stockholders, shortly
         after the merger is completed, you will receive a letter of transmittal
         with instructions informing you how to send in your stock certificates
         to the exchange agent in order to receive the per-share cash amount.
         You should use the letter of transmittal to exchange stock certificates
         for the merger consideration to which you become entitled as a result
         of completion of the merger. You will receive your cash payment as soon
         as practicable after the exchange agent receives your Excel Technology
         stock certificates and any completed documents required in the
         instructions. PLEASE DO NOT SEND ANY STOCK CERTIFICATES WITH YOUR
         PROXY.

Q;       WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A:       For the merger to occur, the merger agreement must be adopted by our
         stockholders. If the stockholders adopt the merger agreement, we expect
         to complete the merger as promptly as practicable following the special
         meeting, subject to the closing conditions contained in the merger
         agreement (see page 30 of this proxy statement). We currently
         anticipate that the closing of the merger will occur during the second
         quarter of calendar year 2006, if we have received by that time the
         requisite stockholder approvals and antitrust regulatory approvals from
         authorities in the United States.

Q:       WHO WILL OWN EXCEL TECHNOLOGY AFTER THE MERGER?

A:       After the merger, Excel Technology will be a wholly owned subsidiary of
         Coherent. Upon completion of the merger, stockholders of Excel
         Technology will no longer have any equity or ownership interest in
         Excel Technology.

                                       ix


Q:       WHAT RIGHTS DO I HAVE IF I OPPOSE THE MERGER?

A:       Excel Technology's stockholders are entitled to exercise appraisal
         rights in connection with the merger. If you do not vote in favor of
         the merger and it is completed, you may dissent and seek payment of the
         fair value of your shares under Delaware law. To do so, however, you
         must comply with all of the required procedures under Delaware law. See
         "Dissenters' Rights of Appraisal" beginning on page 37.

Q:       WHO CAN HELP ANSWER MY OTHER QUESTIONS?

A:       If you have more questions about the merger, need assistance in voting
         your shares or need additional copies of this proxy statement or the
         enclosed proxy card, you should contact:

                                       1


         MERGER CONSIDERATION. If the merger is completed, each share of Excel
Technology common stock that you own will be converted into the right to receive
$30.00 in cash (unless you exercise your appraisal rights under Delaware law).

         TREATMENT OF STOCK OPTIONS. All stock options that are not fully vested
will be vested in connection with the merger. Immediately prior to and
contingent upon the effectiveness of the merger, all outstanding vested stock
options having an exercise price of less than $30.00 per share will be purchased
by Excel Technology for a cash payment equal to the amount by which $30.00 per
share exceeds the exercise price per share for each share of our common stock
subject to the option multiplied by the number of shares issuable upon the
exercise in full of the option (less applicable withholding). See "The
Merger-The Merger Agreement-Treatment of Our Common Stock and Stock Options in
the Merger" on page 24.

THE SPECIAL MEETING OF EXCEL TECHNOLOGY'S STOCKHOLDERS (PAGE 7)

         DATE, TIME AND PLACE. A special meeting of our stockholders will be
held on ______, March ___, 2006, at the offices of Excel Technology, 41 Research
Way, East Setauket, NY 11733, at 10:00 a.m., local time, to:

         o        consider and vote upon the adoption of the merger agreement,

         o        adjourn or postpone the special meeting, if necessary or
                  appropriate, to solicit additional proxies in the event there
                  are not sufficient votes in favor of adoption of the merger
                  agreement at the time of the special meeting, and

         o        transact such other business as may properly come before the
                  meeting or any adjournment or postponement of the meeting.

         RECORD DATE AND VOTING POWER. You are entitled to vote at the special
meeting if you owned shares of our common stock at the close of business on
March 6, 2006, the record date for the special meeting. You will have one vote
at the special meeting for each share of our common stock you owned at the close
of business on the record date. As of the record date there were 12,058,329
shares of our common stock entitled to be voted at the special meeting.

         REQUIRED VOTE. The adoption of the merger agreement requires the
affirmative vote of the holders of a majority of the shares of our common stock
outstanding at the close of business on the record date. Approval of any
proposal to adjourn or postpone the special meeting, if necessary or
appropriate, to solicit additional proxies requires the affirmative vote of a
majority of the votes cast by holders of our common stock present, in person or
represented by proxy, at the special meeting, provided a quorum is present.

UNANIMOUS BOARD RECOMMENDATION (PAGE 15)

         Our board of directors has unanimously:

         o        determined that the merger agreement and the merger are
                  advisable and in the best interests of Excel Technology and
                  our stockholders;

         o        approved the merger agreement; and

         o        recommended that all of our stockholders vote for the adoption
                  of the merger agreement.

                                       2


EXCEL TECHNOLOGY'S REASONS FOR THE MERGER (PAGE 13)

         Our board of directors consulted with senior management and our
financial and legal advisors and considered a number of factors, including those
set forth below, in reaching its decisions to approve the merger agreement and
to recommend that our stockholders vote "FOR" adoption of the merger agreement:

         o        our belief in the likely consolidation of the laser industry,
                  our difficulty in acquiring entities larger than ourselves,
                  and the long term importance of size and mass in reaching
                  foreign markets;

         o        future prospects as an independent company given uncertainties
                  and contingencies associated with projections, economic
                  conditions, competition, and opportunities to make meaningful
                  acquisitions at reasonable prices;

         o        the process through which we, with the assistance of our
                  financial advisors, engaged, or sought to engage, in
                  discussions with entities believed to be the most likely
                  candidates to pursue a business combination with or acquire
                  us, and the fact that no strategic or financial buyer other
                  than Coherent made a written proposal to acquire us;

         o        the unlikely potential for obtaining a superior offer from an
                  alternative purchaser to Coherent in light of the other
                  potential purchasers previously identified and contacted by
                  our management or our financial advisors;

         o        the belief of our board of directors that we have obtained the
                  highest price per share that Coherent is willing to pay and
                  the highest price obtainable on the date of signing of the
                  merger agreement;

         o        the adequacy of Coherent's capital resources, including its
                  borrowing capacity, to pay the merger consideration;

         o        the amount of the merger consideration and the fact that it
                  represents a premium of approximately 6% over the closing
                  price for our common stock on the last trading day prior to
                  the announcement of the signing of the merger agreement and
                  approximately 34% over the average closing price of our common
                  stock during the six month period prior to the announcement of
                  the signing of the merger agreement;

         o        the opinion of UBS Securities, LLC, Excel Technology's
                  financial advisor that, as of the date of such opinion, the
                  merger consideration to be received by holders of our common
                  stock was fair, from a financial point of view, to such
                  holders based on and subject to assumptions made, procedures
                  followed, matters considered and limitations on the scope of
                  the review undertaken as described in such opinion;

         o        the fact that the merger consideration would be paid in cash,
                  which provides certainty of value to our stockholders;

         o        the conditions to the completion of the merger and the
                  circumstances under which Coherent or Excel would have the
                  right to terminate the merger agreement. In addition, the
                  board reviewed the provisions of the merger agreement that
                  prohibits Excel from soliciting any proposal or offer
                  regarding any acquisition and the requirement for Excel to
                  recommend adoption of the merger agreement by its stockholders
                  and the prohibition on the Excel board from withdrawing or
                  modifying its recommendation unless, subject to specified
                  conditions, it has received an unsolicited acquisition
                  proposal. The Excel board also reviewed the various amounts
                  that might be payable in the event the merger agreement is
                  terminated under specified circumstance, noting that while
                  these provisions could have an impact on a third party
                  considering an unsolicited acquisition proposal, the
                  provisions were reasonably necessary to protect both
                  Coherent's and Excel's interests in the context of the
                  proposed merger. In addition, the Excel board found reasonable
                  the views of its legal and financial advisors that the fees
                  were within the range of fees payable in comparable
                  transactions and would not be expected to preclude an
                  unsolicited acquisition proposal for Excel;

         o        the likelihood of closing the merger; and

         o        the availability of appraisal rights to holders of our common
                  stock who dissent from the merger.


         In the course of its deliberations, our board of directors also
considered, among others, the following risks and other countervailing factors:

                                       3


         o        the risk that the merger might not be completed;

         o        the fact that our stockholders, by virtue of the merger
                  consideration consisting solely of cash, will not participate
                  in any of our future earnings or growth and will not benefit
                  from any appreciation in our value following the merger unless
                  they currently have, or acquire in the future, shares of stock
                  or other equity interests in Coherent independently of this
                  merger transaction;

         o        the fact that the merger consideration consists of cash and
                  will, therefore, be taxable to our stockholders for U.S.
                  federal income tax purposes;

         o        the potential disruption to customer, vendor or other
                  commercial relationships to us as a result of the merger;

         o        the restrictions on the conduct of our business prior to the
                  completion of the merger, which may delay or prevent us from
                  undertaking business opportunities that may arise pending
                  completion of the merger; and

         o        the risk of diverting management's focus and resources from
                  other strategic opportunities and from operational matters
                  while working to implement the merger, and the possibility of
                  other management and employee disruption associated with the
                  merger, including the possible loss of key management,
                  technical or other personnel.

The information and factors set forth above includes the material factors
considered by our board of directors. In view of the variety of factors
considered in connection with its evaluation of the merger, our board of
directors did not find it practicable to, and did not, quantify or otherwise
assign relative or specific weights or values to any of these factors and
individual directors may have given different weights to different factors.

OPINION OF UBS SECURITIES LLC, EXCEL TECHNOLOGY'S FINANCIAL ADVISOR (PAGE 15)

         UBS Securities LLC delivered its opinion to our board of directors
that, as of February 17, 2006 (the date of its written fairness opinion) and
based upon and subject to various assumptions made, matters considered and
limitations described in the written opinion, the merger consideration of $30.00
per share payable in cash to be received by holders of our common stock pursuant
to the merger agreement was fair, from a financial point of view, to such
holders.

         The full text of the written opinion of UBS, dated February 17, 2006,
which sets forth the assumptions made, procedures followed, matters considered
and limitations on the review undertaken in connection with the opinion, is
attached as Annex B to this proxy statement and is incorporated into this proxy
statement by reference. You should read the opinion in its entirety. UBS
provided its opinion to inform and assist our board of directors in connection
with its consideration of the merger. The UBS opinion is not a recommendation as
to how any holder of our common stock should vote or act with respect to the
transaction.

WHEN THE MERGER WILL BE COMPLETED  (PAGES 24 AND 30)

         The merger will become effective when the parties file a certificate of
merger with the Secretary of State of Delaware, which filing shall take place on
the day of the closing of the merger, which shall be no later than the second
business day after satisfaction or waiver of all the closing conditions set
forth in the merger agreement, including the following:

         o        adoption of the merger agreement by the holders of at least a
                  majority of our outstanding shares of common stock;

         o        expiration or termination of the Hart-Scott Rodino Antitrust
                  Improvements Act of 1976 (which we refer to as the HSR Act);

         o        the parties respective representations and warranties
                  contained in the merger agreement must be true and correct,
                  except as would not have a material adverse effect;

         o        the parties must each be in compliance in all material
                  respects with their respective covenants contained in the
                  merger agreement;

         o        no material adverse effect with respect to a party shall have
                  occurred; and

                                       4


         o        that certain non-executive employees agree to payment
                  agreements whereby they agree that certain retention bonuses
                  will not be paid by Coherent unless such individuals are
                  employed on the twelve-month anniversary of the closing of the
                  merger.

         If the law permits, either Excel Technology or Coherent could choose to
waive a condition to its obligation to complete the merger even though that
condition has not been satisfied.

         See "The Merger-The Merger Agreement-Conditions to Closing the Merger"
on page 30.

INTERESTS OF OUR DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER (PAGE 20)

         Our directors and executive officers have economic interests in the
merger that are different from, or in addition to, their interests as
stockholders. Our board of directors knew about these additional interests and
considered them when they approved the merger agreement. These interests include
the following:

         o        Under employment agreements that we have entered into with our
                  executive officers, upon the closing of the merger, these
                  executives are entitled to change of control payments, and, if
                  their employment is not continued, certain severance benefits;

         o        Our directors and executive officers have options to purchase
                  Excel Technology common stock at varying prices, all of which
                  are vested. Immediately prior to and contingent upon the
                  effectiveness of the merger, we will purchase all such options
                  having an exercise price of less than $30.00 per share for a
                  cash payment equal to the amount by which $30.00 per share
                  exceeds the exercise price per share for each share of our
                  common stock subject to the option multiplied by the number of
                  shares issuable upon exercise in full of the option.

         o        Our directors and officers will continue to be entitled to
                  indemnification following consummation of the merger pursuant
                  to provisions of the merger agreement.

         o        Howard S. Breslow, Esq., a member of our board of directors,
                  is a member of Breslow & Walker, LLP, our outside general
                  legal counsel, who has represented us in connection with the
                  merger and will receive a legal fee for such services.

DISSENTERS' RIGHTS OF APPRAISAL (PAGE 37 AND ANNEX C)

         Delaware law provides you with appraisal rights in the merger. This
means that if you comply with the procedures for perfecting appraisal rights
under Delaware law, you are entitled to have the fair value of your shares
determined by the Delaware Court of Chancery and to receive a cash payment based
on that valuation instead of the merger consideration. The ultimate amount you
receive in an appraisal proceeding may be more or less than, or the same as, the
amount you would have received under the merger agreement.

         To exercise your appraisal rights, you must deliver a written demand
for appraisal to Excel Technology before the vote on the merger agreement at the
special meeting and you must not vote in favor of the adoption of the merger
agreement. Your failure to follow exactly the procedures specified under
Delaware law will result in the loss of your appraisal rights. A copy of the
relevant provisions of the Delaware General Corporation Law is attached to this
proxy statement as Annex C.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES (PAGE 23)

         If you are a U.S. holder of our common stock, the merger will be a
taxable transaction to you. For U.S. federal income tax purposes, your receipt
of cash in exchange for your shares of Excel Technology common stock generally
will cause you to recognize a gain or loss measured by the difference, if any,
between the cash you receive in the merger and your adjusted tax basis in your
shares. If you are a non-U.S. holder of Excel Technology common stock, the
merger will generally not be a taxable transaction to you under U.S. federal
income tax laws unless you have certain connections to the United States. You
should consult your own tax advisor for a full understanding of the tax
consequences to you of the merger.

                                       5


PROCEDURE FOR RECEIVING MERGER CONSIDERATION (PAGE 24)

         Coherent has appointed U.S. Bank, as payment agent, to coordinate the
payment of the cash merger consideration following the merger. The payment agent
will send you written instructions for surrendering your certificates and
obtaining the cash merger consideration after we have completed the merger.

TERMINATION OF THE MERGER AGREEMENT (PAGE 31)

         The parties may jointly agree to terminate the merger agreement without
completing the merger, even if our stockholders have approved it. In addition,
either party may terminate the merger agreement in the event of any of the
following:

         o        the consummation of the merger has not occurred by July 31,
                  2006 (or October 31, 2006, if it has not occurred because
                  there is in effect an order of a governmental entity that has
                  the effect of making the merger illegal or otherwise
                  prohibiting the consummation of the merger, or the waiting
                  period (or any extensions thereof) to obtain antitrust
                  approval has not expired or been terminated early, or there is
                  pending or threatened action by any governmental entity (a)
                  challenging or seeking to restrain or prohibit completion of
                  the merger, the effect of which if obtained would make the
                  merger illegal or otherwise prohibit consummation of the
                  merger, or (b) seeking to require us or Coherent to divest any
                  assets), but this termination right is not available to a
                  party whose failure to comply with the merger agreement was
                  the principal cause of the failure to complete the merger by
                  that date;

         o        any permanent injunction or other order of a court or other
                  competent authority preventing the consummation of the merger
                  has become final and nonappealable;

         o        our stockholders do not adopt the merger agreement (but this
                  termination right is not available to us if our failure to
                  comply with the merger agreement caused the failure to obtain
                  stockholder approval);

         o        the other party has breached any of its representations,
                  warranties or covenants and the breach cannot be or is not
                  cured within the time allowed, and if not cured, the breach
                  would result in a failure of certain conditions to the merger
                  (and the terminating party has not materially breached the
                  merger agreement); or

         o        an event has occurred which has a material adverse effect on
                  the other party.

         Coherent may also terminate the merger agreement if our board of
directors does or resolves to do any of the following:

         o        withdraws or amends in a manner adverse to Coherent our
                  recommendation in favor of the adoption of the merger by our
                  stockholders;

         o        does not reaffirm such recommendation if requested in writing
                  to do so;

         o        approves or recommends an alternative acquisition proposal;

         o        enters into any agreement accepting an alternative acquisition
                  proposal;

         o        does not send to our stockholders a statement recommending
                  rejection of any tender or exchange offer by a party unrelated
                  to Coherent for shares of our common stock within 10 business
                  days of the announcement of the tender or exchange offer;

         o        materially breaches its obligations under the merger agreement
                  with respect to non-solicitation, notification of unsolicited
                  acquisition proposals, superior offers or changes of our board
                  of directors' recommendation (see "The Merger-The Merger
                  Agreement, "No Solicitation of Transactions" on page 28,
                  "Superior Offers" on page 29 and "Change of Recommendation" on
                  page 29).

         A termination fee of $14,106,154 may be payable by us to Coherent in
connection with the termination of the merger agreement under several
circumstances, including termination by us in connection with a superior offer.
See "Termination Fees" on page 32.

                                       6


         We may also terminate the merger agreement if, prior to the adoption of
the merger agreement, in connection with an acquisition proposal we wish to
accept, (a) we have not breached our obligations under the merger agreement with
respect to the acquisition proposal, the board of directors has determined that
the acquisition proposal constitutes a superior offer, and (c) we pay Coherent a
termination fee of $14,106,154.

EXPENSES (PAGE 32)

         Generally, all fees and expenses incurred in connection with the merger
agreement and the merger will be paid by the party incurring the expenses. We
will be responsible to pay all fees and expenses incurred in relation to the
printing and filing (with the Securities and Exchange Commission) of this Proxy
Statement and Coherent will be responsible to pay the filing fee for the initial
Notification and Report Forms filed with the Federal Trade Commission and the
Department of Justice under the HSR Act. If the merger agreement is terminated
by Coherent because we breached our obligations under the merger agreement with
respect to non-solicitation, notification of unsolicited acquisition proposals,
superior offers or changes of our board of directors' recommendation, then we
will be required to pay all expenses incurred by Coherent and Merger Sub prior
to the termination of the merger agreement up to a maximum of $1,880,921. In
addition, under certain circumstances, we will also be required to pay the
termination fee noted herein.

REGULATORY MATTERS (PAGE 23)

         The HSR Act prohibits us from completing the merger until we have
furnished certain information and materials to the Antitrust Division of the
Department of Justice and the Federal Trade Commission and the required waiting
period has expired or been terminated.


                               THE SPECIAL MEETING

DATE, TIME AND PLACE OF THE SPECIAL MEETING

         This proxy statement is being furnished to our stockholders as part of
the solicitation of proxies by our board of directors for use at the special
meeting to be held on March ___, 2006, at 10:00 a.m., local time, at the offices
of Excel Technology, 41 Research Way, East Setauket, NY 11733 or at any
postponement or adjournment thereof. This proxy statement and the enclosed form
of proxy are first being mailed to our stockholders on or about March __, 2006.

MATTERS TO BE CONSIDERED

         At the special meeting, our stockholders will be asked to consider and
vote upon the following two proposals:

                  o        PROPOSAL NO. 1: To adopt the merger agreement, as the
                           same may be amended from time to time.

                  o        PROPOSAL NO. 2: To grant the persons named as proxies
                           discretionary authority to vote to adjourn or
                           postpone the special meeting, if necessary, to
                           solicit additional proxies if there are not
                           sufficient votes to adopt the merger agreement.

         Our board of directors has unanimously determined that the merger
agreement and the merger are advisable and in the best interests of Excel
Technology and its stockholders and has unanimously approved the merger
agreement. Our board of directors unanimously recommends that you vote "FOR"
adoption of the merger agreement and "FOR" granting the authority to the persons
named as proxies to vote your shares to adjourn or postpone the special meeting,
if necessary, to solicit additional proxies if there are not sufficient votes
for the adoption of the merger agreement.

                                       7


RECORD DATE AND QUORUM

         The holders of record of Excel Technology common stock as of the close
of business on March 6, 2006, the record date for the special meeting, are
entitled to receive notice of, and to vote at, the special meeting. On the
record date, there were 12,058,329 shares of our common stock outstanding and
entitled to vote.

         The holders of a majority of the outstanding shares of our common stock
on the record date represented in person or by proxy will constitute a quorum
for purposes of the special meeting. A quorum is necessary to hold the special
meeting. Stockholders are counted as present at the meeting if they (1) are
present in person or (2) have properly submitted a proxy card or voted by
telephone or by using the Internet. Under the Delaware General Corporation Law,
an abstaining vote and a broker "non-vote" are counted as shares present and
entitled to vote and are, therefore, included for purposes of determining
whether a quorum is present at the special meeting.

         Once a share is represented at the special meeting, it will be counted
for the purposes of determining a quorum at the special meeting and any
postponement or adjournment of the special meeting. However, if a new record
date is set for an adjourned special meeting, then a new quorum will have to be
established.

REQUIRED VOTE

         The adoption of the merger agreement requires the affirmative vote of
the holders of a majority of Excel Technology common stock outstanding and
entitled to vote on the record date. The affirmative vote of a majority of the
shares of Excel Technology common stock represented at the special meeting and
entitled to vote is required to adjourn or postpone the meeting. Each
outstanding share of Excel Technology common stock on the record date entitles
the holder to one vote at the special meeting. Stockholders do not have
cumulative voting rights.

         If your shares are held in "street name" by your broker, bank or other
nominee you should instruct your broker, bank or other nominee how to vote your
shares using the instructions provided by your broker, bank or other nominee. If
you have not received these voting instructions or require further information
regarding these voting instructions, contact your broker, bank or other nominee
and he or she can give you directions on how to vote your shares. You may not
vote such shares unless you have a valid proxy from your broker.

         Under the rules of NASDAQ, brokers, banks or other nominees who hold
shares in "street name" for customers may not exercise their voting discretion
with respect to the approval of non-routine matters such as the merger proposal
or the vote to adjourn and postpone the meeting if deemed necessary to
facilitate the approval of the merger proposal, and thus, absent specific
instructions from the beneficial owner of the shares, brokers, banks and other
nominees are not empowered to vote the shares with respect to the adoption of
the merger agreement (i.e., "broker non-votes"). Shares of Excel Technology
common stock held by persons attending the special meeting but not voting, or
shares for which we have received proxies with respect to which holders have
abstained from voting, will be considered abstentions. Thus, while abstentions
and broker non-votes, if any, will be treated as shares that are present and
entitled to vote at the special meeting for purposes of determining whether a
quorum exists, both will have the same effect as a vote "AGAINST" adoption of
the merger agreement, and abstentions, but not broker non-votes, will have the
same effect as a vote "AGAINST" the proposal to adjourn and postpone the
meeting.

VOTING; REVOCATION

         VOTING BY TELEPHONE OR THE INTERNET. A stockholder may vote his or her
shares by calling the toll-free number indicated on the enclosed proxy card and
following the recorded instructions or by accessing the website indicated on the
enclosed proxy card and following the instructions provided. When a stockholder
votes via the Internet or by telephone, his or her vote is recorded immediately.
We encourage our stockholders to vote using these methods whenever possible.

         VOTING BY PROXY CARD. All shares entitled to vote and represented by
properly executed proxy cards received prior to the special meeting, and not
revoked, will be voted at the special meeting in accordance with the
instructions indicated on those proxy cards. If no instructions are indicated on
a properly executed proxy card, the

                                       8


shares represented by that proxy card will be voted as recommended by our board
of directors. If any other matters are properly presented for consideration at
the special meeting, including, among other things, consideration of a motion to
adjourn the special meeting to another time or place (including, without
limitation, for the purpose of soliciting additional proxies), the persons named
as proxies in the enclosed proxy card and acting thereunder will have discretion
to vote on those matters in accordance with their best judgment. We do not
currently anticipate that any other matters will be raised at the special
meeting. If, however, a matter is properly presented at the special meeting or
any adjournment or postponement of the special meeting, the persons appointed as
proxies will have discretionary authority to vote the shares represented by duly
executed proxies in accordance with their discretion and judgment.

         VOTING BY ATTENDING THE MEETING. A stockholder may also vote his or her
shares in person at the special meeting. A stockholder planning to attend the
special meeting should bring proof of identification for entrance to the special
meeting. If a stockholder attends the special meeting, he or she may also submit
his or her vote in person, and any previous votes that were submitted by the
stockholder, whether by Internet, telephone or mail, will be superseded by the
vote that the stockholder casts at the special meeting. If you hold your shares
of Excel Technology common stock in street name and you want to vote these
shares in person at the special meeting, you will need to obtain a written proxy
in your name from the broker, bank or other nominee who holds your shares.

         CHANGING VOTE; REVOCABILITY OF PROXY. If a stockholder has voted by
telephone or the Internet or by sending a proxy card, the stockholder may change
his or her vote before the special meeting. A stockholder that has voted by
telephone or the Internet may change his or her vote by making a timely and
valid later telephone or Internet vote, as the case may be. Any proxy card given
pursuant to this solicitation may be revoked by the person giving it at any time
before it is voted. A proxy card may be revoked by (1) filing with Excel
Technology's Secretary, at or before the taking of the vote at the special
meeting, a written notice of revocation or a duly executed proxy card, in either
case dated later than the prior proxy card relating to the same shares, or (2)
attending the special meeting and voting in person (although attendance at the
special meeting will not of itself revoke a proxy). Any written notice of
revocation or subsequent proxy card must be received by Excel Technology's
Secretary prior to the taking of the vote at the special meeting. The written
notice of revocation or subsequent proxy card should be hand delivered to Excel
Technology's Secretary or should be sent so as to be delivered to Excel
Technology, Inc., 41 Research Way, East Setauket, NY 11733, Attention:
Secretary.

         If you have instructed your broker, bank or other nominee to vote your
shares, the options for revoking your proxy described in the paragraph above do
not apply and instead you must follow the directions provided by your broker,
bank or other nominee to change these instructions.

EXPENSES OF SOLICITATION OF PROXIES

         Excel Technology will pay the cost of this proxy solicitation. In
addition to soliciting proxies by mail, directors, officers and employees of
Excel Technology may solicit proxies personally and by telephone, facsimile or
other electronic means of communication. These persons will not receive
additional or special compensation for the solicitation services. Excel
Technology will, upon request, reimburse brokers, banks and other nominees for
their expenses in sending proxy materials to their customers who are beneficial
owners and obtaining their voting instructions. Excel Technology has retained
____________ to assist it in the solicitation of proxies for the special meeting
and will pay _________________ customary fees expected to be $______________,
plus reimbursement of out-of-pocket expenses and other customary costs.

                           PROPOSAL NO. 1: THE MERGER


BACKGROUND OF THE MERGER

         Our senior management has periodically reviewed and assessed the
various business trends and conditions impacting Excel Technology and the laser
systems and electro-optical components business generally, and regularly updated
our board of directors regarding these matters. From time to time, our senior
management has also reviewed with our board of directors strategic options
potentially available to us, including growth through customer and product
initiatives, growth by targeted acquisitions of other businesses, and strategic
combination transactions between us and other companies in similar and
complementary lines of business.

         In January 2003, John Ambroseo, Coherent's President and Chief
Executive Officer, phoned Antoine Dominic, our President and Chief Executive
Officer, expressing a possible interest in Coherent acquiring us. The
conversation was very general in nature.

         In May 2003, Mr. Ambroseo phoned Mr. Dominic and asked to meet with him
at the CLEO show in Baltimore, MD. Mr. Dominic asked Don Hill, our Board
Chairman, to join the meeting. The parties met and talks were centered around
Coherent's interest in acquiring us. Messrs. Dominic and Hill told Mr. Ambroseo
that they would be happy to explore anything that might be in the interest of
our stockholders. Mr. Ambroseo expressed a desire to meet again soon.

         In July 2003, Mr. Ambroseo contacted Mr. Dominic and requested that the
parties meet in New York City. A meeting was held at a hotel in New York City.
Present were Mr. Ambroseo, Helene Simonet, an Executive Vice President and the
Chief Financial Officer of Coherent, and Messrs. Dominic and Hill. Mr. Ambroseo
again expressed an interest in acquiring us, and Messrs. Dominic and Hill again
expressed an interest in exploring anything that might be in the interest of our
stockholders. Mr. Ambroseo expressed a desire to intensify talks shortly. Mr.
Dominic again heard from Mr. Ambroseo in August 2003, but further talks did not
take place until March 2005.

         Recognizing the growing importance of size and mass in the laser
industry and the opportunities for consolidation, we increased our efforts to
create size and mass during this interim period. At a board of directors meeting
on October 13, 2003, Mr. Dominic discussed with the board the concept of
acquiring entity S, a sizeable subsidiary of a large industrial entity P. In
late 2003 and early 2004, we had several contacts with entity P regarding the
acquisition of its subsidiary S. The effort was not met with a favorable
response. We continued in our expansion mode with the acquisition of D. Green
(Electronics) Ltd., a small U.K. company, in December 2003, and, in early 2004,
we formed Excel Technology Lanka (Private) Ltd. in Sri Lanka for the purpose of
software development, manufacture of components and accessories, and sales and
marketing.

         In mid 2004, based on discussion with management, it was becoming clear
to our board of directors that, ultimately, the laser industry would be
consolidated, that we would have difficulty in acquiring entities larger than
ourselves, and that there was a limited number of smaller companies
strategically attractive and available to us. The board of directors felt that
our strength in broad based laser solution technology, including galvos, sealed
co(2) lasers, and lamp pumped, diode pumped, pulsed and ultrafast lasers,
coupled with our ability to integrate them into subsystems, systems and work
stations for marking, micro processing, industrial and scientific applications,
among others, made us a prime acquisition platform for a large industrial
company interested in consolidating the industry. Our other alternatives were to
combine with another entity in the laser field or methodically try to grow
ourselves organically. With this in mind, in June 2004, Mr. Hill met with
investment bankers at UBS Securities LLC, an organization that he considered to
be most knowledgeable in the industrial marketplace, and discussed opportunities
for consolidation in the industry. Back in the fall of 2001, an investment
banker currently with UBS had introduced Mr. Hill to large industrial entity X
that evidenced an interest in acquiring us. Mr. Hill had two or three meetings
with large industrial entity X, but large industrial entity X never pursued the
acquisition. At Mr. Hill's meeting with UBS in June 2004, it identified a number
of potential large industrial entities as possible consolidating partners. Prior
to engaging UBS, Messrs. Dominic and Hill spoke with a number of companies in
the laser industry.

                                       10


         In July 2004, Messrs. Dominic and Hill had dinner in New York City with
the CEO and CFO of Laser Company A to discuss strategic options, including
merging the two entities. While strong interest was expressed by Laser Company
A, ultimately it had no desire to pursue a transaction.

         In September 2004, Mr. Hill had lunch with the Chairman and CEO of
Laser Company B to discuss strategic options, including merging the two
entities. Laser Company B had no interest in pursuing discussions at that time.

         In September 2004, we signed an engagement letter with UBS, pursuant to
which we engaged UBS to contact the large industrial entities to explore
consolidation opportunities. UBS proceeded to contact potential partners.

         On November 30, 2004, Mr. Dominic and Mr. Hill, after the execution of
a mutual confidentiality agreement, made a presentation to large industrial
entity X at UBS' offices in New York City. Company X declined to pursue a
transaction.

         On December 31, 2004, Mr. Dominic and Mr. Hill, after the execution of
a mutual confidentiality agreement, made a presentation to large industrial
entity Y in New York City. Company Y declined to pursue a transaction.

         Other entities contacted by UBS at that time declined to meet with us.
UBS had subsequent follow-up conversations with a number of the large industrial
entities, the results of which did not alter their interest in pursuing a
transaction with us.

         In December 2004, Mr. Hill received an email from the CEO of Laser
Company B requesting a meeting in New York City in February 2005. A meeting was
held at such time, during which serious interest was expressed by Laser Company
B in pursuing a transaction. This meeting was followed up by numerous telephone
conversations between Mr. Hill and the CEO of Laser Company B and Mr. Dominic
and the CEO of Laser Company B, during which conversations the CEO of Laser
Company B reiterated a desire to pursue a transaction, but stated that Laser
Company B would have difficulty paying anything more than an insignificant
premium to the then prevailing market price of our common stock which was
approximately $26 per share. Talks continued on and off until late spring 2005,
at which time they ceased.

         In March 2005, Mr. Ambroseo called Mr. Dominic and requested a meeting
in New York City. On March 13, 2005, Messrs. Dominic and Hill met with Mr.
Ambroseo and Paul Crosby, Coherent's Vice President of Corporate Marketing, in
New York City, at which time Mr. Ambroseo again expressed interest in Coherent
acquiring us in an all cash transaction. Messrs. Dominic and Hill repeated a
willingness to pursue anything that might be in the interest of our
stockholders. On March 25, 2005, we entered into a joint confidentiality
agreement with Coherent.

         On April 15, 2005, UBS contacted industrial entity Z. On April 16,
2005, Messrs. Dominic and Hill held a conference call with industrial entity Z,
which declined to pursue a transaction.

         In May 2005, at the request of Laser Company C, Messrs. Dominic and
Hill met at our offices with the CEO and CFO of Laser Company C. Laser Company C
was not of sufficient size to buy us for cash, and we believed that there were
not sufficient synergies to justify a combination of the companies.

         On June 6, 2005, Mr. Hill was notified that Coherent had retained
Merrill Lynch to act as Coherent's financial advisors in connection with the
proposed transaction.

         On June 23, 2005, we received a non-binding term sheet from Coherent
proposing the purchase by Coherent of all of our outstanding shares at a per
share price of $29, representing a premium of 21.9% to the three-month moving
average price of our common stock. On June 29, 2005, our board of directors
considered the

                                       11


proposal. After consultation with our financial advisors, advice from counsel as
to the board's fiduciary obligation to stockholders, and the experience gained
in canvassing the market, the board resolved that UBS communicate a
counter-proposal of $30 per share to Coherent's financial advisors. The
non-binding counter-proposal was agreed to by Coherent as the basus upon which
to continue discussions between the two companies.

         On August 11, 2005, Messrs. Dominic and Hill made presentations to
Messrs. Ambroseo, Crosby and Ms. Simonet at UBS' offices in New York City. Also
present at the meeting were representatives from Merrill Lynch and UBS.
Approximately two weeks later, Merrill Lynch contacted UBS to report that
Coherent wanted to alter the mix of consideration from all cash to a combination
of approximately equal parts cash and stock. This was presented to our board of
directors by Mr. Hill on September 1, 2005. The revised terms were acceptable to
our board, subject to appropriate due diligence on Coherent and its operations,
and such fact was conveyed to Coherent.

         In September 2005, at Mr. Dominic's request, Mr. Hill asked UBS to
contact selected financial buyers regarding a possible transaction. UBS
contacted several financial buyers, and no contacted party expressed interest in
pursuing a transaction. After UBS contacted several financial buyers, it became
apparent that no counter-proposal transaction with a financial buyer would match
or exceed the $30 per share price being proposed by Coherent.

         Beginning in September 2005, we started to provide Coherent with
non-public due diligence information.

         On November 14, 2005, Coherent provided a draft of a definitive
agreement to us.

         In early January 2006, Mr. Ambroseo had a telephone conversation with
Mr. Hill, and proposed changing the consideration back to all cash to simplify
the transaction, which proposal was amenable to our board. On January 27, 2006,
we received a revised draft of the definitive agreement, which was finalized
over the next few weeks through extensive negotiations between us, our legal
counsel and UBS and Coherent, its legal counsel and its financial advisors on
matters concerning, among other things, the payment of expenses and termination
fees and retention bonuses for non-executive employees.

         On February 17, 2006, our board of directors met telephonically to
review and consider the transaction with Coherent. Our legal counsel reviewed
the principal provisions of the proposed merger agreement that had been
distributed to the directors prior to the meeting and discussed the sequence of
events to move to the closing of the merger. Representatives of UBS joined the
meeting and presented their evaluation of the proposed transaction and described
the financial analysis performed and the procedures followed with respect to
such evaluation. UBS also described the bases and methods that were utilized in
developing its fairness opinion. UBS then delivered its oral opinion (later
confirmed in writing) to the effect that, as of such date and based upon and
subject to the various assumptions made, matters considered and limitations
described in its written opinion, the merger consideration of $30.00 per share
to be received by the holders of our common stock was fair, from a financial
point of view, to such holders. In light of these considerations and the factors
described in "The Merger-Reasons for the Merger" in this proxy statement, our
board of directors unanimously determined that the merger agreement and the
merger are advisable and in the best interests of Excel Technology and our
stockholders, approved the merger agreement, and recommended that all of our
stockholders vote for the adoption of the merger agreement. On February 17,
2006, the board of directors of Coherent approved the merger agreement and
authorized the merger.

         On February 20, 2006, the parties executed and delivered their
respective signature pages to the merger agreement. On February 21, the parties
issued a press release announcing the execution of the merger agreement.

                                       12


REASONS FOR THE MERGER

         In reaching its decision to approve the merger agreement, and to
recommend that our stockholders vote to adopt the merger agreement, our board of
directors consulted with management and our financial and legal advisors. Our
board of directors considered the following factors and potential benefits of
the merger, each of which it believed supported its decision:

         o        our belief in the likely consolidation of the laser industry,
                  our difficulty in acquiring entities larger than ourselves,
                  and the long term importance of size and mass in reaching
                  foreign markets;

         o        management's projections of our internal growth and future
                  earnings, the inherent uncertainties and contingencies
                  associated with projections, and the economic and competitive
                  market conditions affecting us;

         o        our current and future opportunities to grow through
                  meaningful acquisitions at reasonable prices if we were to
                  remain as an independent publicly traded company;

         o        the unlikely potential stockholder value that our board of
                  directors believed might result from other possible
                  alternatives to the proposed merger, including the alternative
                  of continuing to operate on a stand-alone basis or seeking to
                  grow through acquisitions, as well as the risks and
                  uncertainties associated with these alternatives;

         o        the process through which we, with the assistance of our
                  financial advisors, engaged, or sought to engage, in
                  discussions with entities believed to be the most likely
                  candidates to pursue a business combination with or acquire
                  us, as further described above under "Background of the
                  Merger," and the fact that no strategic or financial buyer
                  other than Coherent made a written proposal to acquire us;

         o        the unlikely potential for obtaining a superior offer from an
                  alternative purchaser to Coherent in light of the other
                  potential purchasers previously identified and contacted by
                  our management or our financial advisors;

         o        the belief of our board of directors that we have obtained the
                  highest price per share that Coherent is willing to pay and
                  the highest price obtainable on the date of signing of the
                  merger agreement, including the $1.00 per share increase in
                  the cash merger consideration over the original price offered
                  by Coherent;

         o        the adequacy of Coherent's capital resources, including its
                  borrowing capacity, to pay the merger consideration;

         o        the historical market prices, volatility and recent trading
                  activity of our common stock, and the fact that the $30.00 per
                  share to be paid for each share of our common stock in the
                  merger represents:

                           o        a premium of approximately 6% over the
                                    closing price of our common stock on
                                    February 17, 2006, which was the last
                                    trading day prior to the announcement of the
                                    merger; and

                           o        a premium of approximately 21% over the
                                    average closing price of our common stock
                                    during the six-month period prior to
                                    February 17 2006;

         o        the fact that the merger consideration consists solely of
                  cash, which provides our stockholders with certainty of value
                  for their shares of our common stock;

         o        our board of directors' belief, in light of its knowledge of
                  the business and competitive environment in which we operate,
                  that the merger is more favorable to our stockholders than any
                  other alternative reasonably available to us;

         o        UBS's opinion addressed to our board of directors that, as of
                  February 17, 2006 (the date of its opinion), and subject to
                  the various assumptions made, matters considered, and
                  limitations described in the opinion, the merger consideration
                  to be received by our holders of common stock pursuant to the
                  merger agreement was fair, from a financial point of view, to
                  such holders, together with the financial analyses performed
                  by UBS in connection with the preparation of its opinion and
                  presented by UBS to our board of directors (see "The
                  Merger--Opinion of UBS Securities LLC -Excel Technology's
                  Financial Advisor" and Annex B to this proxy statement);

                                       13


         o        the terms and conditions of the merger agreement resulting
                  from the arm's length negotiations between us and Coherent, as
                  reviewed by our board of directors with our legal advisors,
                  including the conditions to the completion of the merger and
                  the circumstances under which Coherent or Excel would have the
                  right to terminate the merger agreement. In addition, the
                  board reviewed the provisions of the merger agreement that
                  prohibits Excel from soliciting any proposal or offer
                  regarding any acquisition and the requirement for Excel to
                  recommend adoption of the merger agreement by its stockholders
                  and the prohibition on the Excel board from withdrawing or
                  modifying its recommendation unless, subject to specified
                  conditions, it has received an unsolicited "superior"
                  acquisition proposal. The Excel board also reviewed the
                  various amounts that might be payable in the event the merger
                  agreement is terminated under specified circumstance, noting
                  that while these provisions could have an impact on a third
                  party considering an unsolicited acquisition proposal, the
                  provisions were reasonably necessary to protect both
                  Coherent's and Excel's interests in the context of the
                  proposed merger. In addition, the Excel board found reasonable
                  the views of its legal and financial advisors that the
                  termination fee was within the range of fees payable in
                  comparable transactions and would not be expected to preclude
                  an unsolicited acquisition proposal for Excel;

         o        the limited number and nature of the conditions to Coherent's
                  obligation to complete the merger, including (but not limited
                  to) the absence of a financing condition;

         o        the definition of "material adverse effect," which includes
                  negotiated exceptions providing, among other things, that a
                  material adverse effect will not include changes, events or
                  circumstances to the extent resulting from any of the
                  following:

                           o        compliance by us with the terms and
                                    conditions of the merger agreement;

                           o        the announcement or pendency of the merger
                                    agreement;

                           o        any change in our stock price or trading
                                    volume (although the facts or circumstances
                                    giving rise to such change may be taken into
                                    account);

                           o        any failures by us to meet our revenue or
                                    earnings estimates (although the facts and
                                    circumstances giving rise to such failure
                                    may be taken into account);

                           o        changes affecting the industry generally in
                                    which we operate or the United States
                                    economy generally, that do not
                                    disproportionately affect us in any material
                                    respect;

                           o        changes affecting general worldwide economic
                                    or capital market conditions that do not
                                    disproportionately affect us in any material
                                    respect;

         o        the availability of appraisal rights to holders of our common
                  stock who comply with all of the required procedures under
                  Delaware law, which allow those holders to seek appraisal of
                  the fair value of their shares as determined by the Delaware
                  Court of Chancery (see "Rights of Appraisal" and Annex C).

         The Excel Technology board of directors also considered, among others,
the following risks and other countervailing factors:

         o        the risk that the merger might not be completed in a timely
                  manner or at all;

         o        the possibility that United States antitrust regulatory
                  authorities might seek to impose conditions on or enjoin or
                  otherwise prevent or delay the merger;

         o        the fact that, in the event that any of the other conditions
                  to the completion of the merger are not satisfied, Coherent
                  would not be required to consummate the merger even if the
                  merger agreement is adopted by our stockholders;

         o        the interests of our directors and executive officers in the
                  merger as described under "The Merger-Interests of our
                  Directors and Executive Officers in the Merger;"

         o        the fact that our stockholders, by virtue of the merger
                  consideration consisting solely of cash, will not participate
                  in any of our future earnings or growth and will not benefit
                  from any appreciation in our value following the merger unless
                  they currently have, or acquire in the future, shares of stock
                  or other equity interests in Coherent independently of this
                  merger transaction;

         o        the fact that the merger consideration consists of cash and
                  will, therefore, be taxable to our stockholders for U.S.
                  federal income tax purposes;

                                       14


         o        the restrictions on our ability to solicit or engage in
                  discussions or negotiations regarding alternative business
                  combination transactions, subject to specified exceptions, and
                  the requirement that we pay a termination fee in the event we
                  receive and close on a superior acquisition proposal, which
                  may discourage a competing proposal to acquire us that may be
                  more advantageous to our stockholders;

         o        the potential disruption to customer, vendor or other
                  commercial relationships to us as a result of the announcement
                  of the merger agreement and the ultimate announcement of the
                  merger;

         o        the restrictions on the conduct of our business prior to the
                  completion of the merger, requiring us to conduct our business
                  in the ordinary course, subject to specific limitations, which
                  may delay or prevent us from undertaking business
                  opportunities that may arise pending completion of the merger;
                  and

         o        the risk of diverting management's focus and resources from
                  other strategic opportunities and from operational matters
                  while working to implement the merger, and the possibility of
                  other management and employee disruption associated with the
                  merger, including the possible loss of key management,
                  technical or other personnel.

         After taking into account all of the factors set forth above, as well
as others, our board of directors determined that the potential benefits of the
merger outweigh the potential risks and that the merger is advisable, fair to
and in our best interests and that of our stockholders. While our board of
directors as a whole did not assign relative weights to the above factors or the
other factors considered by it, individual members of our board of directors may
have given different weights to different factors. In addition, our board of
directors did not reach any specific conclusion on each factor considered, but,
with the assistance of its advisors, conducted an overall analysis of these
factors.

RECOMMENDATION OF OUR BOARD OF DIRECTORS

         After careful consideration, our board of directors, by unanimous vote:

         o        has determined that the merger agreement and the merger are
                  advisable and in the best interests of Excel Technology and
                  its stockholders;

         o        has approved the merger agreement; and

         o        RECOMMENDS THAT EXCEL TECHNOLOGY'S STOCKHOLDERS VOTE "FOR" THE
                  ADOPTION OF THE MERGER AGREEMENT AND "FOR" GRANTING THE
                  AUTHORITY TO THE PERSONS NAMED AS PROXIES TO VOTE TO ADJOURN
                  OR POSTPONE THE SPECIAL MEETING, IF NECESSARY, TO SOLICIT
                  ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES FOR THE
                  ADOPTION OF THE MERGER AGREEMENT.

OPINION OF UBS SECURITIES, LLC - EXCEL TECHNOLOGY'S FINANCIAL ADVISOR

         On February 17, 2006, UBS delivered to the Excel Technology board of
directors, an oral opinion, which opinion was confirmed by delivery of a written
opinion dated the same date, to the effect that, as of that date and based on
and subject to various assumptions made, matters considered and limitations
described in the opinion, the per share consideration to be received by the
holders of Excel Technology's common stock in the proposed transaction was fair,
from a financial point of view, to such holders.

         The full text of UBS' opinion describes the assumptions made,
procedures followed, matters considered and limitations on the review undertaken
by UBS. The opinion is attached as Appendix B and is incorporated into this
proxy statement by reference. UBS' opinion was provided for the benefit of the
Excel Technology's board of directors in connection with, and for the purposes
of, its consideration of the proposed transaction. UBS' OPINION IS DIRECTED ONLY
TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE PER SHARE CONSIDERATION
TO BE RECEIVED BY EXCEL TECHNOLOGY'S COMMON STOCK HOLDERS AND DOES NOT ADDRESS
ANY OTHER ASPECT OF THE PROPOSED TRANSACTION OR ANY RELATED TRANSACTION. THE
OPINION DOES NOT ADDRESS THE RELATIVE MERITS OF THE PROPOSED TRANSACTION AS
COMPARED TO OTHER BUSINESS STRATEGIES OR TRANSACTIONS THAT MIGHT BE AVAILABLE TO
EXCEL TECHNOLOGY OR THE UNDERLYING BUSINESS DECISION OF EXCEL TECHNOLOGY TO
EFFECT THE PROPOSED TRANSACTION. THE OPINION DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY STOCKHOLDER OF EXCEL TECHNOLOGY AS TO HOW TO VOTE OR ACT
WITH RESPECT TO THE PROPOSED TRANSACTION. YOU ARE ENCOURAGED TO READ THE OPINION
CAREFULLY IN ITS

                                       15


ENTIRETY. The summary of UBS' opinion below is qualified in its entirety by
reference to the full text of UBS' opinion.

         At Excel Technology's direction, UBS was not asked to, and it did not,
offer any opinion as to the material terms (other than the merger consideration
to be received by the holders of Excel Technology's common stock) of the merger
agreement or the form of the proposed transaction. In rendering its opinion, UBS
also assumed, with Excel Technology's consent, that the final executed merger
agreement would not differ in any material respect from the draft merger
agreement that UBS examined prior to rendering its opinion, that each of Excel
Technology and Coherent would comply with all the material terms of the merger
agreement, and that the proposed transaction would be consummated in accordance
with the terms of the merger agreement without any adverse waiver or amendment
of any material terms or condition thereof. UBS also assumed that all
governmental, regulatory or other consents and approvals necessary for the
consummation of the proposed transaction will be obtained without any material
adverse effect on Excel Technology or the proposed transaction.

         In arriving at its opinion, UBS, among other things:

         o        reviewed certain publicly available business and historical
                  financial information relating to Excel Technology and
                  Coherent;

         o        reviewed certain internal financial information and other data
                  relating to the business and financial prospects of Excel
                  Technology including estimates and financial forecasts for
                  calendar years 2006 and 2007 prepared by management of Excel
                  Technology, that were provided to UBS by Excel Technology and
                  not publicly available, as well as publicly available Wall
                  Street research estimates for Excel Technology;

         o        conducted discussions with members of the senior managements
                  of Excel Technology concerning the businesses and financial
                  prospects of Excel Technology;

         o        reviewed publicly available financial and stock market data
                  with respect to certain other companies UBS believed to be
                  generally relevant;

         o        compared the financial terms of the proposed transaction with
                  the publicly available financial terms of certain other
                  transactions UBS believed to be generally relevant;

         o        reviewed current and historical market prices of Excel
                  Technology's common stock;

         o        reviewed the merger agreement; and

         o        conducted such other financial studies, analyses and
                  investigations, and considered such other information, as UBS
                  deemed necessary or appropriate.

         At Excel Technology's request, UBS contacted third parties to solicit
indications of interest in a possible acquisition of, or possible business
combination with, Excel Technology. In connection with its review, with the
consent of Excel Technology, UBS did not assume any responsibility for
independent verification of any of the information that was reviewed by UBS for
the purpose of its opinion and, with the consent of Excel Technology, UBS relied
on that information being complete and accurate in all material respects. In
addition, with the consent of Excel Technology, UBS did not make any independent
evaluation or appraisal of any of the assets or liabilities, contingent or
otherwise, of Excel Technology or Coherent, and was not furnished with any such
evaluation or appraisal. With respect to the financial forecasts and estimates,
UBS assumed, at the direction of Excel Technology, that they have been
reasonably prepared on a basis reflecting the best currently available estimates
and judgments of the management of Excel Technology as to the future performance
of Excel Technology. UBS' opinion was necessarily based on economic, monetary,
market and other conditions as in effect on, and information made available to
UBS as of, the date of its opinion.

                                       16


         In connection with rendering its opinion, UBS performed a variety of
financial and comparative analyses, which are summarized below. The following
summary is not a complete description of all analyses performed and factors
considered by UBS in connection with its opinion. The preparation of a financial
opinion is a complex process involving subjective judgments and is not
necessarily susceptible to partial analysis or summary description.

         UBS believes that its analyses and the summary below must be considered
as a whole and that selecting portions of its analyses and factors or focusing
on information presented in tabular format, without considering all analyses and
factors or the narrative description of the analyses, could create a misleading
or incomplete view of the processes underlying UBS' analyses and opinion. None
of the analyses performed by UBS were assigned greater significance or reliance
by UBS than any other. UBS did not form an opinion as to whether any individual
analysis or factor, whether positive or negative, considered in isolation,
supported or failed to support UBS' opinion. UBS arrived at its ultimate opinion
based on the results of all analyses undertaken by it and assessed as a whole.

         The estimates of Excel Technology's future performance provided by
Excel Technology management in or underlying UBS's analyses are not necessarily
indicative of future results or values, which may be significantly more or less
favorable than those estimates. In performing its analysis, UBS considered
industry performance, general business and economic conditions and other
matters, many of which are beyond Excel Technology's control. Estimates of the
financial value of companies do not necessarily purport to be appraisals or
reflect the prices at which companies actually may be sold.

         The decision to enter into the merger agreement and to agree to the
merger consideration negotiated between Excel Technology and Coherent was solely
that of the Excel Technology board of directors. UBS' opinion and financial
analyses were only one of many factors considered by the Excel Technology board
of directors in its evaluation of the proposed transaction and should not be
viewed as determinative of the views of Excel Technology's board of directors or
management with respect to the merger and the merger consideration.

         The following is a brief summary of the material financial analyses
performed by UBS and reviewed with the Excel Technology board of directors in
connection with UBS' opinion relating to the proposed transaction. THE FINANCIAL
ANALYSES SUMMARIZED BELOW INCLUDE INFORMATION PRESENTED IN TABULAR FORMAT. IN
ORDER TO FULLY UNDERSTAND UBS' FINANCIAL ANALYSES, THE TABLES MUST BE READ
TOGETHER WITH THE TEXT OF EACH SUMMARY. THE TABLES ALONE DO NOT CONSTITUTE A
COMPLETE DESCRIPTION OF THE FINANCIAL ANALYSES. CONSIDERING THE DATA BELOW
WITHOUT CONSIDERING THE FULL NARRATIVE DESCRIPTION OF THE FINANCIAL ANALYSES,
INCLUDING THE METHODOLOGIES AND ASSUMPTIONS UNDERLYING THE ANALYSES, COULD
CREATE A MISLEADING OR INCOMPLETE VIEW OF UBS' FINANCIAL ANALYSES.


         ANALYSIS OF SELECTED PUBLICLY TRADED COMPANIES

         UBS compared selected financial information and operating statistics of
Excel Technology to corresponding financial information and operating statistics
of the following selected publicly held companies that UBS considered reasonably
comparable:

         o        Coherent, Inc.

         o        Newport Corporation

         o        Rofin-Sinar Technologies, Inc.

         UBS calculated the multiples of enterprise value (which consists of
market value of the particular company's equity, plus the particular company's
debt and minority interest, less cash and cash equivalents) to the following
financial information and operating statistics for each of Excel Technology and
the selected companies based on closing stock prices as of February 14, 2006:

                                       17


         o        calendar years 2005 and 2006 estimated revenue;

         o        calendar years 2005 and 2006 estimated earnings before
                  interest, taxes, depreciation and amortization, or EBITDA;

         UBS calculated the multiples of stock price to the following financial
information for each of Excel Technology and the selected companies based on
closing stock prices as of February 14, 2006, and, in the case of Excel
Technology, at the $30.00 per share merger consideration to be paid in the
proposed transaction:

         o        calendar years 2005 and 2006 estimated diluted earnings per
                  share, or EPS

         Estimated financial data for the selected companies was based on
various publicly available Wall Street research reports. UBS then calculated the
mean, median, high and low enterprise value and stock price multiples for the
universe of selected publicly traded companies. UBS compared the resulting range
of multiples for the selected companies to Excel Technology's multiples based
(1) on the closing price of Excel Technology's common stock on February 14,
2006, and (2) on the proposed merger consideration of $30.00 per share, in each
case using estimated financial data for Excel Technology (a) based on various
publicly available Wall Street analyst research reports, and (b) provided by
Excel Technology's management. The results of UBS' calculations are presented in
the table below:

         UBS noted none of the selected companies is either identical or
directly comparable to Excel Technology and that any analyses of selected
companies necessarily involve complex considerations and judgments concerning
financial and operating characteristics and other factors that could affect the
public trading or acquisition values of the companies concerned.

         ANALYSIS OF SELECTED PRECEDENT TRANSACTIONS

         UBS analyzed certain information for the following nine selected
transactions in the laser and marking industries announced since 1998. The
transactions considered and the month and year each transaction was announced
were as follows:

                                       18

- ---------------------------------------------------------------------------------------


         For each of the selected transactions, UBS calculated and compared the
resulting multiples of enterprise value (which consists of market value of the
particular company's equity, plus the particular company's debt and minority
interest, less cash and cash equivalents) to the following financial information
and operating statistics for the target company:

         o        latest twelve-months, or LTM, sales as of the latest fiscal
                  quarter immediately preceding the announcement of the relevant
                  transaction for which quarterly financials were available; and

         o        LTM EBITDA as of the latest fiscal quarter immediately
                  preceding the announcement of the relevant transaction for
                  which quarterly financials were available.

         Estimated financial data for the selected target companies was based on
public filings. UBS utilized estimated financial data for Excel Technology as
provided by Excel Technology's management. UBS then calculated the mean, median,
high and low enterprise value multiples for the selected companies. The results
of UBS' calculations are presented in the table below:

                                    TOTAL ENTERPRISE VALUE/LTM
                                   ----------------------------

         UBS noted that none of the selected precedent transactions is either
identical or directly comparable to the proposed transaction and that any
analysis of selected precedent transactions necessarily involves complex
considerations and judgments concerning financial and operating characteristics
and the other factors that could affect the acquisition values of the companies
concerned.

         OTHER FACTORS

         In rendering its opinion, UBS also reviewed and considered other
information and data, including:

                                       19


         o        historical and expected financial results of Excel Technology;

         o        historical trading prices and trading volumes of Excel
                  Technology's common stock during the period from February 14,
                  2003 through February 14, 2006;

         o        the premiums implied in the proposed transaction based on the
                  merger consideration of $30.00 per share and (a) the closing
                  price of Excel Technology's common stock on February 14, 2006
                  and on the one week, one month, three months, six months and
                  one year immediately preceding February 14, 2006 and (b) the
                  average daily closing prices of Excel Technology's common
                  stock over the one-week, one-month, three-month, six-month and
                  one-year periods preceding February 14, 2006;

         o        certain publicly available Wall Street research reports for
                  Excel Technology;

         o        historical and expected financial statistics of selected
                  publicly held companies that UBS considered reasonably
                  comparable; and

         o        a comparison of financial forecasts and estimates provided by
                  Excel Technology in November 2004 to the actual financial
                  results of Excel Technology for calendar years 2004 and 2005.

         MISCELLANEOUS

         Under the terms of its engagement, Excel Technology has agreed to pay
UBS a $500,000 fee upon delivery of its opinion and a $2,500,000 transaction fee
payable upon consummation of the proposed transaction, against which the opinion
fee will be credited. UBS may also be entitled to receive additional
compensation for its financial advisory services, in an amount not to exceed
$500,000, payable at the sole and absolute discretion of the Board of Directors
of Excel Technology upon consummation of the proposed transaction. In addition,
Excel Technology has agreed to reimburse UBS for its reasonable expenses,
including fees and disbursements of counsel, and to indemnify UBS and related
parties against liabilities, including liabilities under federal securities
laws, relating to, or arising out of, its engagement.

         Excel Technology selected UBS as a financial advisor in connection with
the transaction because UBS is an internationally recognized investment banking
firm with substantial experience in similar transactions and is familiar with
Excel Technology and its business. UBS is continually engaged in the valuation
of businesses and their securities in connection with mergers and acquisitions,
leveraged buyouts, negotiated underwritings, competitive bids, secondary
distributions of listed and unlisted securities and private placements.

         In the ordinary course of business, UBS, its successors and affiliates
may hold or trade, for their own accounts and the accounts of their customers,
securities of Excel Technology and Coherent and, accordingly, may at any time
hold a long or short position in such securities.

INTERESTS OF OUR DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER

         In considering the recommendation of our board of directors with
respect to the merger, you should be aware that our directors and executive
officers have interests in the merger that are different from, or in addition
to, the interests of our stockholders generally. These interests may create
potential conflicts of interests and, to the extent material, are described
below. Our board of directors was aware of these interests and considered them,
among other matters, in approving the merger agreement.

                                       20


         EMPLOYMENT AGREEMENTS AND CHANGE OF CONTROL PAYMENTS

         We have entered into employment agreements with our executive officers
that contain protective change in control arrangements. A summary of the
material provisions of these agreements is provided below:

         J. DONALD HILL. Mr. Hill, our Chairman of the Board, has an employment
agreement which expires on October 9, 2007. Mr. Hill's employment agreement
provides that (a) in the event his employment is terminated without cause, he is
entitled to receive his base salary ($175,000) for a period of two years from
termination, and (b) in the event of a Change of Control, he is entitled to a
payment of $1,000,000, plus a gross up of any excise tax payable by him with
respect to any portion of such payment constituting an excess parachute payment
under Section 280G of the Internal Revenue Code. Change of Control, as defined
in Mr. Hill's employment agreement, will include the merger with Coherent. In
connection with the merger, Mr. Hill's employment agreement will be cancelled
and he will receive a payment of $500,000 ($850,000 less than that to which he
would be otherwise entitled) in complete satisfaction of the obligation for a
Change of Control Payment and severance. Coherent is not entering into a new
employment agreement with Mr. Hill in connection with the merger.

         ANTOINE DOMINIC. Mr. Dominic, our President and Chief Executive
Officer, has an employment agreement which has an expiration date of October 9,
2006; but, unless the parties reach an agreement for continued employment prior
to the expiration of the term (there being an obligation for the parties to
enter into good faith negotiations regarding continued employment at least 90
days prior to the expiration thereof), the employment agreement automatically is
renewed for a period of one year, and continues to renew at the end of each
subsequent year until (a) the parties agree to new terms of employment, or (b)
employment is terminated pursuant to the express provisions of the employment
agreement (e.g. he is terminated without cause). Currently, Mr. Dominic receives
a base salary of $550,000 and has a bonus plan providing for bonus payments, on
a quarterly basis, equal to 3% of pre-tax profits if such profits for the
quarter do not exceed $1,500,000, 4% of pre-tax profits if such profits for the
quarter exceed $1,500,000 but do not exceed $2,500,000, and 5% of pre-tax
profits if such profits for the quarter exceed $2,500,000. Mr. Dominic's
employment agreement provides that (a) in the event his employment is terminated
without cause, he is entitled to receive (1) his base salary for a period of two
years from termination, and (2) his bonus compensation through (A) October 9,
2006 (in the event his employment is terminated without cause prior thereto), or
(B) the date of termination (in the event his employment agreement is terminated
without cause after October 9, 2006), in either case (A) or (B), in an amount
not less than that received for the same applicable period of the prior year,
and (b) in the event of a Change of Control, he is entitled to a payment equal
to 300% of his base salary for the year in which the Change of Control takes
place (but in no event less than $1,000,000) plus a gross up of any excise tax
payable by him with respect to any portion of such payment constituting an
excess parachute payment under Section 280G of the Internal Revenue Code. Change
of Control, as defined in Mr. Dominic's employment agreement, will include the
merger with Coherent. In connection with the merger, Mr. Dominic's employment
agreement will be cancelled and he will receive a payment of $4,700,000 in
complete satisfaction of the obligation for a Change of Control payment,
severance and future bonuses. Coherent is not entering into a new employment
agreement with Mr. Dominic in connection with the merger.

         ALICE VARISANO. Ms. Varisano, our Chief Financial Officer, has an
employment agreement which expires on December 28, 2008. Ms. Varisano's
employment agreement provides that (a) in the event her employment agreement is
terminated due to a Change of Control she is entitled to receive a severance
payment equal to two years of compensation (including base salary of $275,000,
expense allowance of $25,000, and a minimum bonus of $50,000), and (b) in the
event of a Change of Control, she is entitled to receive a payment of $300,000,
plus a gross up of any excise tax payable by her with respect to any portion of
such payment constituting an excess parachute payment under Section 280G of the
Internal Revenue Code. Change of Control, as determined in Ms. Varisano's
employment agreement, will include the merger with Coherent. In connection with
the merger, Ms. Varisano's employment agreement will be cancelled and she will
receive a payment of $900,000 in complete satisfaction of the obligation for a
change of Control payment and severance. Coherent is not entering into a new
employment agreement with Ms. Varisano in connection with the merger.

         PURCHASE OF STOCK OPTIONS

         Our directors and executive officers have options to purchase shares of
Excel Technology common stock at varying prices, all of which are fully vested.
Immediately prior to and contingent upon the effectiveness of the merger, Excel
Technology will purchase all of such options having an exercise price of less
than $30.00 per share for a cash payment equal to the amount by which $30.00 per
share exceeds the exercise price per share for each share of our common stock
subject to the option multiplied by the number of shares issuable upon exercise
in full of the option. The following table sets forth the number of stock
options owned by each of our directors and executive officers which will be
purchased in connection with the merger, the weighted average exercise price,
and the aggregate consideration to be received therefor:

  Name of Director       Number of Options    Weighted Average      Aggregate
Or Executive Officer      to be Purchased      Exercise Price     Consideration*

                  * These amounts may be reduced by any applicable withholding
requirements.

         INDEMNIFICATION AND INSURANCE

         For six years after the completion of the merger, the certificate of
incorporation and bylaws of the company surviving the merger will contain
provisions regarding exculpation, indemnification and advancement of expenses
which are at least as favorable, to the directors and officers who were
indemnified by Excel Technology immediately prior to completion of the merger,
as the exculpation, indemnification and advancement provisions that were
contained in the certificate of incorporation and bylaws of Excel Technology in
effect at the time the merger agreement was executed.

         Coherent has also agreed to have the Company surviving the merger use
all reasonable efforts to cause to be maintained directors' and officers'
liability insurance, for events occurring prior to the effective time,
containing terms no less favorable to the insured than the current insurance
maintained by us to cover the persons serving as officers and directors
immediately prior to the effective time, for a period of six years after
completion of the merger, although Coherent will not be obligated to make annual
premium payments in excess of 200% of the premiums currently paid by Excel
Technology for insurance.

         This continued indemnification and coverage merely extends beyond
closing of the merger the protections for our directors and officers that
existed prior to the date of the merger agreement.

         INTEREST OF HOWARD S. BRESLOW, ESQ. AND EXCEL TECHNOLOGY'S LAW FIRM

         Howard S. Breslow, Esq., a member of our board of directors, is a
member of Breslow & Walker, LLP, our outside general legal counsel. Breslow &
Walker, LLP has represented Excel Technology in connection with the merger and
will receive a fee for legal services of $1,300,000 in connection with the
merger.

         THE INTERESTS DESCRIBED ABOVE MAY INFLUENCE OUR DIRECTORS AND EXECUTIVE
OFFICERS IN MAKING THEIR RECOMMENDATIONS THAT YOU VOTE IN FAVOR OF THE ADOPTION
OF THE MERGER AGREEMENT. YOU SHOULD BE AWARE OF THESE INTERESTS WHEN YOU
CONSIDER OUR BOARD'S RECOMMENDATION THAT YOU VOTE IN FAVOR OF THE MERGER
AGREEMENT.

                                       22


MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

         The following is a discussion of the material federal income tax
consequences of the merger to holders of Excel Technology common stock. The
discussion is based upon the Internal Revenue Code, Treasury regulations, IRS
rulings and judicial and administrative decisions in effect as of the date of
this proxy statement, all of which are subject to change (possibly with
retroactive effect) or to different interpretations. The following discussion is
limited to the material federal income tax aspects of the merger to a
stockholder of Excel Technology who is a citizen or resident of the United
States and who, on the date on which the merger is completed, holds shares of
Excel Technology common stock as a capital asset. The following discussion does
not address taxpayers subject to special treatment under federal income tax
laws, such as insurance companies, financial institutions, dealers in
securities, tax-exempt organizations, S corporations and taxpayers subject to
the alternative minimum tax. In addition, the following discussion may not apply
to stockholders who acquired their shares of Excel Technology common stock upon
the exercise of employee stock options or otherwise as compensation for services
or who hold their shares as part of a hedge, straddle or conversion transaction.

         The following discussion does not address potential foreign, state,
local and other tax consequences of the merger. All stockholders are urged to
consult their own tax advisors regarding the federal income tax consequences, as
well as the foreign, state and local tax consequences, of the disposition of
their shares in the merger.

         For federal income tax purposes, the merger will be treated as a
taxable sale or exchange of Excel Technology common stock for cash by each Excel
Technology stockholder (including any stockholder who properly exercises
dissenters' rights). Accordingly, the federal income tax consequences to the
Excel Technology stockholders receiving cash generally will be as follows:

         o        The stockholder will recognize a capital gain or loss upon the
                  disposition of the stockholder's shares of Excel Technology
                  common stock pursuant to the merger.

         o        The capital gain or loss, if any, will be long-term with
                  respect to shares of Excel Technology common stock held for
                  more than twelve months as of the effective time of the
                  merger.

         o        The amount of capital gain or loss recognized by each
                  stockholder will be measured by the difference between the
                  amount of cash received by the stockholder in connection with
                  the merger, or cash received in connection with the exercise
                  of dissenters' rights, and the stockholder's adjusted tax
                  basis in the shares of Excel Technology common stock at the
                  effective time of the merger.

         Cash payments made pursuant to the merger, including any cash paid to a
stockholder who properly exercises dissenters' rights, will be reported to Excel
Technology stockholders and the Internal Revenue Service to the extent required
by the Internal Revenue Code and applicable regulations. These amounts will
ordinarily not be subject to withholding of U.S. federal income tax. However, a
backup withholding of the tax at a rate of 28% may apply to a stockholder who
fails to supply Excel Technology or U.S. Bank, as payment agent, with the
stockholder's taxpayer identification number or has received notice from the
Internal Revenue Service of a failure to report all interest and dividends
required to be shown on the stockholder's federal income tax returns.
Accordingly, each Excel Technology stockholder will be asked to provide a
correct taxpayer identification number on a Substitute Form W-9 which is to be
included in the appropriate letter of transmittal for the shares of Excel
Technology common stock.

DELISTING AND DEREGISTRATION OF EXCEL TECHNOLOGY COMMON STOCK

         Following the completion of the merger, our common stock will be
delisted from the Nasdaq National Market and deregistered under the Exchange
Act, and we will no longer file periodic reports with the Securities Exchange
Commission.

                                       23


REGULATORY APPROVALS

         Under the HSR Act and related rules, Excel Technology and Coherent may
not complete the merger until the expiration of a 30-day waiting period
following the filing of notification reports with the Department of Justice and
the Federal Trade Commission by Coherent and Excel Technology, unless a request
for additional information or documentary material is received from the Federal
Trade Commission or the Department of Justice or unless early termination of the
waiting period is granted. If, within the initial 30-day waiting period, either
the Department of Justice or the Federal Trade Commission requests additional
information or documentary material concerning the merger, then the waiting
period will be extended until the 30th calendar day after the date of
substantial compliance with the request by both parties, unless earlier
terminated by the Federal Trade Commission or Department of Justice. Only one
extension of the waiting period pursuant to a request for additional information
is authorized by the HSR Act. Thereafter, the waiting period may be extended
only by court order or with the consent of the parties.

THE MERGER AGREEMENT

         The following summary describes the material provisions of the merger
agreement. This summary does not purport to be complete and may not contain all
of the information about the merger agreement that is important to you. The
following summary is qualified in its entirety by reference to the complete text
of the merger agreement, which is attached to this proxy statement as Annex A.
We encourage you to read it carefully in its entirety for a more complete
understanding of the merger agreement.

         THE MERGER

         Merger Sub, a wholly owned subsidiary of Coherent, will merge with an
into Excel Technology with Excel Technology surviving as a wholly owned
subsidiary of Coherent. Merger Sub was created solely for the purpose of the
merger and has no significant assets and no operations of its own.

         EFFECTIVE TIME OF THE MERGER

         The merger will become effective when Excel Technology and Coherent
file a certificate of merger with the Secretary of State of the State of
Delaware (or at such later time as may be agreed upon in writing by Excel
Technology and Coherent and specified in the certificate of merger), which
filing will take place on the day of the closing of the merger. The closing of
the merger will take place no later than the second business day after the
satisfaction or waiver of all of the closing conditions set forth in the merger
agreement or at such other time as Excel Technology and Coherent agree upon in
writing.

         TREATMENT OF OUR COMMON STOCK AND STOCK OPTIONS IN THE MERGER

         COMMON STOCK. At the effective time of the merger, each issued and
outstanding share of our common stock will be cancelled and converted into the
right to receive $30.00 in cash, without interest (other than shares held by our
stockholders exercising dissenters' rights to appraisal).

         STOCK OPTIONS. Immediately prior to and contingent upon the
effectiveness of the merger, each outstanding stock option (all of which are
vested or will vest as a result of the merger) having an exercise price of less
than $30.00 per share will be purchased by Excel Technology for a cash payment
equal to the amount by which $30.00 per share exceeds the exercise price per
share for each share of our common stock subject to the option multiplied by the
number of shares issuable upon the exercise in full of the option.

         EXCHANGE AND PAYMENT PROCEDURES

         At or prior to the effective time of the merger, Coherent will deposit
an amount of cash sufficient to pay the merger consideration to each of our
stockholders with a payment agent. As promptly as reasonably practicable after
the effective time, the payment agent will mail a letter of transmittal and
instructions to the Excel Technology stockholders. The letter of transmittal and
instructions will instruct you how to surrender Excel Technology common stock
certificates in exchange for the merger consideration.

                                       24


         You will not be entitled to receive the merger consideration until you
surrender your Excel Technology stock certificate or certificates to the payment
agent, together with a duly completed and executed letter of transmittal.

         No interest will be paid or will accrue on the cash payable upon
surrender of the certificates. Coherent or the payment agent will be entitled to
deduct and withhold, and pay to the appropriate taxing authorities, any
applicable taxes from the merger consideration. Any sum which is withheld and
paid to a taxing authority by the payment agent will be deemed to have been paid
to the person to whom the consideration would otherwise have been paid.

         None of the payment agent, Excel Technology or Coherent will be liable
to any person for any cash delivered to a public official under any applicable
abandoned property, escheat or similar law. Any portion of the merger
consideration deposited with the payment agent that remains undistributed to the
holders of certificates evidencing shares of our common stock for nine months
after the effective time of the merger, will be delivered to the surviving
corporation to be held in trust for the holders. Holders of certificates who
have not surrendered their certificates prior to the delivery of the funds to
the surviving corporation may only look to the surviving corporation for the
payment of the merger consideration.

         If you have lost a certificate, or if it has been stolen or destroyed,
then before you will be entitled to receive the merger consideration, you will
have to make an affidavit of the loss, theft or destruction before the payment
agent issues the cash constituting the merger consideration and Coherent may, in
its discretion and as a condition precedent to the issuance of the cash, require
you to post a bond in an amount as it may reasonably direct as indemnity against
any claim that may be made against Coherent, Excel Technology or the payment
agent.

         In all cases, the merger consideration will be paid only in accordance
with the procedures set forth in the merger agreement and letter of transmittal.

warranties made by Coherent and Merger Sub to us. The representations and
warranties relate to, among other things:

         o        their corporate organization, good standing, power to do
                  business and Merger Sub;

         o        their corporate power and authority to enter into the merger

         o        the required consents and approvals of governmental entities

         o        the availability of cash at closing to pay the merger
                  consideration.

         The representations and warranties of each of the parties to the merger
agreement will expire upon the effective time of the merger.

         The representations and warranties of each of the parties to the merger
agreement have been made solely for the benefit of the other party or parties,
as applicable, to the merger agreement, and such representations and warranties
should not be relied on by any other person. In addition, our representations
and warranties were made as of a specified date, may be qualified by a standard
of materiality different from what might be viewed as material to stockholders,
may have been used for the purpose of allocating risk between the respective
parties rather than establishing matters as facts, or are qualified by the
information in the disclosure schedules that we have delivered to Coherent in
connection with signing the merger agreement. The disclosure schedules referred
to above contain information (including information that has been included in
our prior public disclosures, as well as potential additional non-public
information) that modifies, qualifies and creates exceptions to the
representations and warranties set forth in the merger agreement, regardless of
whether an exception is noted. Accordingly, you should not rely on the
representations and warranties as current characterizations of factual
information about us, Coherent or Merger Sub. Moreover, information concerning
the subject matter of the representations and warranties may have changed since
the date of the merger agreement, which subsequent information may or may not be
fully reflected in our public disclosures.

         CONDUCT OF BUSINESS OF EXCEL TECHNOLOGY PENDING THE MERGER

         We have agreed that prior to completion of the merger, unless Coherent
otherwise consents in writing, we will conduct our business in the ordinary
course of business consistent with past practice, continue to pay our debts and
taxes when due, and use all reasonable efforts consistent with past practice, to
preserve intact our business organization, keep available the services of our
present executive officers and employees, and preserve our relationships with
customers, suppliers, licensors, licensees and other persons with whom we do
business consistent with our past practices.

                                       26


         We have also agreed that prior to the merger, subject to certain
exceptions or unless Coherent gives its prior written consent, we will not, nor
will we permit any of our subsidiaries to, do any of the following:

         o        enter into a new line of business;

         o        declare or pay dividends or other distributions on capital
                  stock, or split, combine, reclassify or otherwise issue
                  capital stock, except for any such transaction in the ordinary
                  course of business consistent with past practice by a wholly
                  owned subsidiary that remains a wholly owned subsidiary;

         o        purchase, redeem or acquire any of our capital stock or the
                  capital stock of any of our subsidiaries;

         o        issue, sell, pledge or otherwise encumber any capital stock or
                  other voting securities or other securities convertible into
                  capital stock or other voting securities, except: issuances on
                  exercise of outstanding options and limited grants of new
                  options in the ordinary course of business consistent with
                  past practice;

         o        amend our governing documents or those of our subsidiaries;

         o        acquire by merger, consolidation, purchase of equity or asset
                  purchase any business or any party or division thereof;

                  alliance;

         o        sell, lease, license or encumber any assets, except for the
                  sale, license, encumbrance or disposition of property or

                  of business;

         o        make any loans, advances or capital contributions to, or
                  investments in, any other person, except for loans to or

                  advances for expenses in the ordinary course of business
                  consistent with past practice;

         o        change our methods or principles of accounting, except as
                  required by U.S. generally accepted accounting principles;

         o        make any tax election or accounting method change reasonably
                  likely to materially adversely affect our tax liability or tax
                  attributes, or settle any material income tax liability or
                  consent to any extension or waiver of any limitation period
                  with respect to taxes;

         o        revalue any assets;

         o        pay or settle liabilities or litigation other than in the
                  ordinary course of business and requiring monetary payment not
                  in excess of certain specified thresholds or fail to enforce
                  any confidentiality or similar agreement;

         o        make certain changes in employee compensation, employee plans,
                  company options or employment agreements;

         o        grant any exclusive rights with respect to our intellectual
                  property;

         o        enter into contracts binding us, the surviving corporation, or
                  Coherent (after the completion of the merger) to any
                  noncompetition, exclusivity or similar restrictions;

         o        enter into any agreement that would give a third party after
                  the merger any right to any intellectual property or access to
                  any source code;

         o        hire employees other than in the ordinary course of business;

                  another person, or enter into an agreement to maintain any
                  financial statement condition of any other person, or enter
                  into any arrangement having the economic effect of any of the
                  foregoing, except in the ordinary course of business
                  consistent with past practice;

                  aggregate; or

         o        agree in writing or otherwise to take any of the actions

                                       27


         STOCKHOLDERS MEETING AND DUTY TO RECOMMEND

         We have agreed to call a meeting of our stockholders promptly following
the execution of the merger agreement (in any event within 45 days after this
proxy statement is cleared by the Securities and Exchange Commission, or if no
comments are received from the Securities and Exchange Commission on or prior to
the expiration of the ten day waiting period, within 55 days after the filing of
this proxy statement with the Securities and Exchange Commission) for the
purpose of obtaining adoption by our stockholders of the merger agreement and to
use all reasonable efforts to solicit the adoption of the merger agreement by
our stockholders. Our board of directors has unanimously agreed to recommend the
adoption of the merger agreement by our stockholders. Subject to certain
restrictions, prior to the adoption by our stockholders of the merger agreement
with Coherent, our board, however, is permitted to withhold, withdraw or modify,
in a manner adverse to Coherent, its recommendation, in each case if our board
determines in good faith, after consultation with its outside financial and
legal advisors, that the failure to do so would reasonably be expected to breach
its fiduciary duties under applicable law. See "The Merger-The Merger
Agreement-Change of Recommendation" on page 28 for more details on our board of
directors' rights to withdraw its recommendation in any manner adverse to
Coherent.

         NO SOLICITATION OF TRANSACTIONS

         The merger agreement contains detailed provisions prohibiting us from
seeking an alternative transaction to the merger. Under these "no solicitation"
provisions, we agree that we may not, subject to specific exceptions described
below, directly or indirectly:

         o        solicit, initiate, encourage, knowingly facilitate or induce
                  any inquiry with respect to, or the making, submission or
                  announcement of, any acquisition proposal (as described
                  below);

         o        participate in any discussions or negotiations regarding, or
                  furnish to any person any nonpublic information with respect
                  to, or take any other action to facilitate any inquiries or
                  the making of any proposal that constitutes or may reasonably
                  be expected to lead to, any acquisition proposal;

         o        engage in discussions with any person with respect to any
                  acquisition proposal, except as to the existence of these "no
                  solicitation" provisions;

         o        approve, endorse or recommend any acquisition proposal;

         o        release any third party from any confidentiality or standstill
                  agreement, or fail to enforce or grant any waiver, consent or
                  request to, any acquisition proposal under such agreement; or

         o        enter into any letter of intent or other agreement related to
                  any acquisition proposal.

         For purposes of the merger agreement, an "acquisition proposal" is any
offer or proposal with respect to Excel Technology or its subsidiaries relating
to any of the following:

         o        the acquisition by a third party or group unrelated to
                  Coherent of more than a 10% interest in our outstanding voting
                  securities or those of any of our subsidiaries;

         o        any tender offer or exchange offer that would result in a
                  third party or group unrelated to Coherent beneficially owning
                  securities representing 10% or more of our outstanding voting
                  securities or those of any of our subsidiaries;

         o        any merger, consolidation, business combination or similar
                  transaction;

         o        any sale, lease (other than in the ordinary course of
                  business), exchange, transfer, license (other than in the
                  ordinary course of business), acquisition or disposition of
                  more than 10% of our consolidated assets; or

         o        any liquidation or dissolution of Excel Technology.

         Under the merger agreement, we agreed to cease all existing activities,
discussions or negotiations with any third parties conducted prior to February
20, 2006, with respect to any acquisition proposal.

         As promptly as practicable (and in any event no later than 24 hours)
after our receipt of any acquisition proposal or any related request for
nonpublic information or inquiry, we must notify Coherent of the material terms
and conditions of the proposal, request or inquiry, the identity of the person
or group making the proposal, request or inquiry, and all related written
materials provided in connection with the proposal, request or inquiry. We also

                                       28


agreed to provide Coherent with two (2) business days prior notice (or such
lesser prior notice as is provided to our board of directors) of any meeting of
our board of directors to discuss the acquisition proposal.

         SUPERIOR OFFERS

         If at any time prior to the adoption of the merger agreement by our
stockholders, we receive an unsolicited bona fide written acquisition proposal
that our board of directors determines in good faith, after consultation with
our outside legal counsel and our financial advisor, is or is reasonably likely
to result in a superior offer (as described below), then we may, but only if and
to the extent our board of directors reasonably determines in good faith, after
receipt of advice from our outside legal counsel, that the failure to provide
the information or enter into the negotiations would reasonably be expected to
result in a breach of fiduciary duties under applicable law, (a) furnish
nonpublic information to the third party making the proposal as long as (i)
before providing any nonpublic information, we give Coherent no less than 24
hours written notice of our intention to do so, and (ii) we receive from the
third party a customary confidentiality agreement, and we furnish any nonpublic
information provided to the third party at the same time to Coherent (to the
extent not previously provided to Coherent), and (b) enter into negotiations
with the third party as long as we give Coherent 24 hours prior written notice
thereof.

         For purposes of the merger agreement, a superior offer is defined as an
unsolicited, bona fide written acquisition proposal (except that each reference
to 10% described above under the description of an acquisition proposal is
substituted by 50%) that the board of directors has in good faith concluded,
after consultation with our outside legal counsel and financial advisor, taking
into account among other things, all legal, financial, regulatory or other
aspects of the offer and the person making the offer, to be more favorable from
a financial point of view, to our stockholders than the terms of the merger
agreement with Coherent (taking into account all of the terms of any proposal by
Coherent to amend or modify the merger agreement) and reasonably capable of
being consummated without unreasonable delay.

         CHANGE OF RECOMMENDATION

         Solely in response to the receipt of a superior offer, our board of
directors is permitted to withhold, withdraw, modify or amend its unanimous
recommendation in favor of the merger and enter into a written agreement
memorializing such superior offer, and, in the case of a superior offer that is
a tender offer or exchange offer made directly to our stockholders, may
recommend that our stockholders accept the tender offer or exchange offer, if
all of the following conditions are met:

         o        a superior offer has been made and not withdrawn;

         o        our stockholders meeting has not yet occurred;

         o        we have (a) provided Coherent prior written notice stating
                  expressly (i) that we have received a superior offer, (ii) the
                  final terms and conditions of the superior offer and the
                  identity of the third party making the superior offer, and
                  (iii) that we intend to withhold, withdraw, amend or modify
                  our recommendation in favor of the merger with Coherent, and
                  the manner in which we intend to do so, (b) provided Coherent
                  all written materials delivered to the third person in
                  connection with the superior offer, and (c) made available to
                  Coherent all other information made available to the third
                  person in connection with the superior offer;

         o        our board of directors has concluded in good faith, after
                  receipt of advice of its outside legal counsel, that the
                  failure to change the recommendation or enter into an
                  agreement with respect to the superior offer is reasonably
                  likely to result in a breach of its fiduciary obligations to
                  our stockholders under applicable law;

         o        we have not breached our obligations with respect to the
                  stockholder meeting, non-solicitation of acquisition
                  proposals, notification of acquisition proposals, superior
                  offers and change of our board of directors' recommendation;

         o        at least two (2) business days shall have elapsed since we
                  gave Coherent notice of our intent to change our
                  recommendations;

         o        during such two day period, we engage in good faith
                  negotiations with Coherent with respect to adjustments to the
                  terms of the merger agreement that Coherent may suggest; and

                                       29


         o        our board of directors, after consultation with our legal
                  counsel and financial advisor does not conclude that the
                  acquisition proposal no longer constitutes a superior offer.

         Unless the merger agreement is terminated, our obligation to hold the
stockholders' meeting to adopt the merger agreement is not limited by the
receipt of any acquisition proposal, or by any change of recommendation, and we
cannot submit any acquisition proposal to our stockholders.

         The merger agreement permits us and our board of directors to comply
with Rule 14d-9 and Rule 14e-2 under the Exchange Act, with regard to an
acquisition proposal that we receive.

         If we enter into an agreement with respect to a superior offer, we may
terminate the merger agreement, subject to payment to Coherent of a $14,106,154
termination fee as further described under "The Merger -The Merger
Agreement-Termination" on page 31 and "Termination Fees" on page 32.

         AGREEMENT TO USE COMMERCIALLY REASONABLE EFFORTS

         We and Coherent have agreed to use all commercially reasonable efforts
to consummate the merger and any other transactions contemplated by the merger
agreement, including to cause the conditions of the merger to be satisfied,
obtain governmental approvals, defend any suits challenging the merger and
obtain third party consents, except that neither we nor Coherent will be
required to take any action of divestiture.

         We and Coherent have also agreed to use all reasonable efforts to
obtain any antitrust regulatory approvals, including without limitation U.S.
antitrust approval.

                                    agreement was the principal cause of the
                                    failure to close the merger by that date);

                                    terminate the merger agreement for this
                                    reason will not be available to us if the
                                    failure to obtain stockholder approval was
                                    caused by our action or failure to act and
                                    that action or failure to act was a breach
                                    of the merger agreement; or

                                    representation or warranty became untrue and
                                    the breach is incapable of being cured or

                                             favor of the adoption of the merger
                                             by our stockholders;

                                             five (5) days after Coherent

                                             recommendation be reaffirmed;

                                             recommends an alternative
                                             acquisition proposal;

                                    o        we enter into a letter of intent or

                                             alternative acquisition proposal;

                                    o        we do not send our stockholders a
                                             statement that our board of
                                             directors recommends rejection of a
                                             tender or exchange offer commenced
                                             by a party unrelated to Coherent
                                             within 10 business days of the
                                             announcement of any tender or
                                             exchange offer for our shares; or

                           o        we have materially breached in any material
                                    respect our obligations under the merger
                                    agreement with respect to non-solicitation
                                    of acquisition proposals, notification of
                                    unsolicited acquisition proposals, superior
                                    offers or change of recommendation.

         o        by us if, prior to the adoption of the merger agreement by our
                  stockholders, in connection with an acquisition proposal we
                  wish to accept, (a) we have not willfully breached our
                  obligations under the merger agreement with respect to
                  non-solicitation of acquisition proposals, notification of
                  unsolicited acquisition proposals, superior offers or change
                  of recommendation, (b) the board of directors has determined
                  that the acquisition proposal constitutes a superior offer,
                  and (c) we pay Coherent a termination fee of $14,106,154.

         FEES AND EXPENSES

         The merger agreement provides, generally, that regardless of whether
the merger is consummated, all fees and expenses incurred by the parties in
connection with the merger will be borne by the party incurring such fees and
expenses. We will be responsible to pay all fees and expenses incurred in
relation to the printing and filing (with the Securities and Exchange
Commission) of this Proxy Statement, and Coherent is responsible to pay the
filing fee for the initial Notification and Report forms filed with the Federal
Trade Commission and the Department of Justice under the HSR Act. If the merger
agreement is terminated by Coherent because we breached our obligations under
the merger agreement with respect to non-solicitation, notification of
unsolicited acquisition proposals, superior offers or changes of our board of
directors' recommendation, then we will be required to pay all expenses incurred
by Coherent and Merger Sub prior to the termination of the merger agreement, up
to a maximum of $1,880,821.

         TERMINATION FEES

         We are to pay Coherent a termination fee of $14,106,154, if the merger
agreement is terminated under certain circumstances.

         If we terminate the merger agreement because we accept a superior offer
or Coherent terminates the merger agreement because a triggering event (as
described above) has occurred or because we materially breached our obligations
under the merger agreement with respect to non-solicitation, notification of
unsolicited acquisition proposals, superior offers or changes of our board of
directors' recommendation, we must pay the termination fee to

                                       32


Coherent no later than two business days after we terminate the merger
agreement. In the latter case, the termination fee is to be reduced by the
expenses paid to Coherent as discussed above.

         If an alternative acquisition proposal has been publicly disclosed at
the date the merger agreement is terminated, and within 12 months following the
termination of this agreement an acquisition of the Company is consummated or
the Company enters into an agreement providing for the acquisition of the
Company and such acquisition is consummated within 18 months of the termination
of the merger agreement, then within two (2) business days after the
consummation of the acquisition, we must pay the termination fee to Coherent if
the merger agreement was terminated as follows:

                  o        by either us or Coherent because the merger is not
                           consummated by July 31, 2006 (or October 31, 2006 if
                           it is not consummated because of an order of a
                           governmental entity that has the effect of making the
                           merger illegal or otherwise prohibiting the
                           consummation of the merger, or the waiting period (or
                           any extension thereof) to obtain antitrust approval

                           pending or threatened any action by a governmental
                           entity (a) challenging or seeking to restrain or
                           prohibit completion of the merger, the effect of
                           which if obtained would make the merger illegal or
                           otherwise prohibit consummation of the merger, or (b)
                           seeking to require us or Coherent to divest any
                           assets;

                  o        by either us or Coherent because our stockholders
                           fail to approve the transaction;

                  o        by Coherent due to our breach of our representations,
                           warranties, or covenants that would result in the
                           failure to satisfy the closing conditions relating to
                           our representations, warranties or covenants, which
                           we fail to cure within the specified period.

         AMENDMENT, WAIVER AND EXTENSION OF THE MERGER AGREEMENT

         The merger agreement may be amended by mutual written consent of the
parties, subject to applicable laws. Any amendment proposed after obtaining the
required approval of our stockholders may not be made without the further
approval of our stockholders if stockholder approval is required by applicable
law or Nasdaq rules.

         At any time prior to completion of the merger, either we or Coherent
may extend the other's time for the performance of any of the obligations or
other acts under the merger agreement, waive any inaccuracies in the other's
representations and warranties and waive compliance by the other with respect to
any of the agreements or conditions contained in the merger agreement.

  PROPOSAL NO. 2: GRANTING OF PROXY TO ADJOURN OR POSTPONE THE SPECIAL MEETING

         If we fail to receive a sufficient number of votes to approve Proposal
No. 1 to adopt the merger agreement, we may propose to adjourn the special
meeting for the purpose of soliciting additional proxies to approve such
Proposal No. 1. We will not propose to adjourn or postpone the special meeting
if there are sufficient votes to approve Proposal No. 1. If Proposal No. 2 to
adjourn or postpone our special meeting for the purpose of soliciting additional
proxies is submitted to our stockholders for approval, the affirmative vote of
the holders of a majority of our outstanding shares of common stock, present in
person or represented by proxy at the special meeting and entitled to vote
thereon, that are voted for or against Proposal No. 2 will be required.

         THE EXCEL TECHNOLOGY BOARD OF DIRECTORS RECOMMENDS THAT OUR
STOCKHOLDERS VOTE TO GRANT THE PERSONS NAMED AS PROXIES DISCRETIONARY AUTHORITY
TO VOTE TO ADJOURN OR POSTPONE THE SPECIAL MEETING, IF NECESSARY, TO SOLICIT
ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES TO APPROVE PROPOSAL NO. 1
TO ADOPT THE MERGER AGREEMENT.

                         DISSENTERS' RIGHTS OF APPRAISAL

         Under Delaware law, you have the right to demand appraisal in
connection with the merger and to receive, instead of the merger consideration,
payment in cash for the fair value of your Excel Technology common stock as
determined by the Delaware Court of Chancery. Excel Technology stockholders
electing to exercise appraisal rights must comply with the provisions of Section
262 of the Delaware General Corporation law in order to perfect their rights.
Excel Technology will require strict compliance with the statutory procedures.

         The following is intended as a brief summary of the material provisions
of the Delaware statutory procedures required to be followed by a stockholder in
order to demand and perfect appraisal rights. This summary, however, is not a
complete statement of all applicable requirements and is qualified in its
entirety by reference to Section 262 of the Delaware General Corporation Law,
the full text of which appears in Annex C to this proxy statement.

         Section 262 requires that stockholders be notified not less than 20
days before the special meeting to vote on the adoption of the merger agreement
that appraisal rights will be available. A copy of Section 262 must be included
with that notice. This proxy statement constitutes our notice to our
stockholders of the availability of appraisal rights in connection with the
merger in compliance with the requirements of Section 262. If you wish to
consider exercising your appraisal rights, you should carefully review the text
of Section 262 contained in Annex C since failure to timely and properly comply
with the requirements of Section 262 will result in the loss of your appraisal
rights under Delaware law.

         If you elect to demand appraisal of your shares, you must satisfy each
of the following conditions:

         o        You must deliver to Excel Technology a written demand for
                  appraisal of your shares before the vote with respect to the
                  merger agreement is taken at the special meeting. This written
                  demand for appraisal must be in addition to and separate from
                  any proxy or vote abstaining from or voting against the
                  adoption of the merger agreement. Voting against or failing to
                  vote for the adoption of the merger agreement by itself does
                  not constitute a demand for appraisal within the meaning of
                  Section 262. Failure to vote against adoption of the merger
                  agreement will not constitute a waiver of your appraisal
                  rights.

         o        You must not vote in favor of the adoption of the merger
                  agreement. A vote in favor of the adoption of the merger
                  agreement, by proxy or in person, will constitute a waiver of
                  your appraisal rights in respect of the shares so voted and
                  will nullify any previously filed written demands for
                  appraisal.

         o        You must continuously hold the shares from the date of making
                  the demand through the effective time of the merger since
                  appraisal rights will be lost if the shares are transferred
                  before the effective time of the merger.

         o        You must file a petition in the Chancery Court demanding a
                  determination of the fair value of the shares within 120 days
                  after the effective time of the merger.

         If you fail to comply with any of these conditions and the merger is
completed, you will be entitled to receive the cash payment for your shares of
Excel Technology common stock as provided for in the merger agreement, but you
will have no appraisal rights with respect to your shares of Excel Technology
common stock. A proxy card which is signed and does not contain voting
instructions will, unless revoked, be voted "FOR" the adoption of the merger
agreement and will constitute a waiver of your right of appraisal and will
nullify any previous written demand for appraisal.

         All demands for appraisal should be in writing and addressed to Excel
Technology, Inc. 41 Research Way, East Setauket, NY 11733, Attention: Secretary,
and must be delivered before the vote on the merger agreement is taken at the
special meeting, and should be executed by, or on behalf of, the record holder
of the shares in respect of which appraisal is being demanded. The demand must
reasonably inform Excel Technology of the identity of the stockholder and the
intention of the stockholder to demand appraisal of his, her or its shares.

                                       37


         To be effective, a demand for appraisal by a holder of Excel Technology
common stock must be made by, or in the name of, the registered stockholder,
fully and correctly, as the stockholder's name appears on his or her stock
certificate(s). The demand should specify the holder's name and mailing address
and the number of shares registered in the holder's name and must state that the
person intends thereby to demand appraisal of the holder's shares in connection
with the merger. BENEFICIAL OWNERS WHO DO NOT ALSO HOLD THE SHARES OF RECORD MAY
NOT DIRECTLY MAKE APPRAISAL DEMANDS TO EXCEL TECHNOLOGY. THE BENEFICIAL HOLDER,
IN THESE CASES, MUST HAVE THE REGISTERED OWNER SUBMIT THE REQUIRED DEMAND IN
RESPECT OF THOSE SHARES. If shares are owned of record in a fiduciary capacity,
such as by a trustee, guardian or custodian, execution of a demand for appraisal
should be made in that capacity; and if the shares are owned of record by more
than one person, as in a joint tenancy or tenancy in common, the demand should
be executed by or for all joint owners. An authorized agent, including an
authorized agent for two or more joint owners, may execute the demand for
appraisal for a stockholder of record; however, the agent must identify the
record owner or owners and expressly disclose the fact that, in executing the
demand, he or she is acting as agent for the record owner. A record owner, such
as a broker, who holds shares as a nominee for others may exercise his or her
right of appraisal with respect to the shares held for one or more beneficial
owners, while not exercising this right for other beneficial owners. In that
case, the written demand should state the number of shares as to which appraisal
is sought. Where no number of shares is expressly mentioned, the demand will be
presumed to cover all shares held in the name of the record owner.

         IF YOU HOLD YOUR SHARES OF EXCEL TECHNOLOGY COMMON STOCK IN A BROKERAGE
ACCOUNT OR IN OTHER NOMINEE FORM AND YOU WISH TO EXERCISE APPRAISAL RIGHTS, YOU
SHOULD CONSULT WITH YOUR BROKER OR THE OTHER NOMINEE TO DETERMINE THE
APPROPRIATE PROCEDURES FOR THE MAKING OF A DEMAND FOR APPRAISAL BY THE NOMINEE.

         Within 10 days after the effective time of the merger, the surviving
corporation must give written notice that the merger has become effective to
each Excel Technology stockholder who has properly filed a written demand for
appraisal and who did not vote in favor of the merger agreement. At any time
within 60 days after the effective time, any stockholder who has demanded an
appraisal has the right to withdraw the demand and to accept the cash payment
specified by the merger agreement for the stockholder's shares of Excel
Technology common stock. Within 120 days after the effective time, either the
surviving corporation or any stockholder who has complied with the requirements
of Section 262 may file a petition in the Delaware Court of Chancery demanding a
determination of the fair value of the shares held by all stockholders entitled
to appraisal. The surviving corporation has no obligation and has no present
intention to file a petition in the event there are dissenting stockholders.
Accordingly, it is the obligation of the applicable stockholders to initiate all
necessary action to perfect their appraisal rights in respect of shares of Excel
Technology common stock within the time prescribed in Section 262. The failure
of a stockholder to file a petition within the period specified could nullify
the stockholder's previously written demand for appraisal.

         If a petition for appraisal is duly filed by a stockholder and a copy
of the petition is delivered to the surviving corporation, the surviving
corporation will then be obligated, within 20 days after receiving service of a
copy of the petition, to provide the Chancery Court with a duly verified list
containing the names and addresses of all stockholders who have demanded an
appraisal of their shares and with whom agreements as to the value of their
shares have not been reached. After notice to dissenting stockholders, the
Chancery Court is empowered to conduct a hearing upon the petition, and to
determine those stockholders who have complied with Section 262 and who have
become entitled to the appraisal rights provided thereby. The Chancery Court may
require the stockholders who have demanded payment for their shares to submit
their stock certificates to the Register in Chancery for notation of the
pendency of the appraisal proceedings; and if any stockholder fails to comply
with that direction, the Chancery Court may dismiss the proceedings as to that
stockholder.

         After determination of the stockholders entitled to appraisal of their
shares of Excel Technology common stock, the Chancery Court will appraise the
shares, determining their fair value exclusive of any element of value arising
from the accomplishment or expectation of the merger, together with a fair rate
of interest, if any, to be paid upon the amount determined to be the fair value.
When the value is determined, the Chancery Court will direct the payment of the
value, with interest thereon accrued during the pendency of the proceeding, if
the Chancery Court so determines, to the stockholders entitled to receive the
same, upon surrender by the holders of the certificates representing those
shares.

                                       38


         In determining fair value and, if applicable, a fair rate of interest,
the Chancery Court is required to take into account all relevant factors. YOU
SHOULD BE AWARE THAT THE FAIR VALUE OF YOUR SHARES AS DETERMINED UNDER SECTION
262 COULD BE MORE, THE SAME, OR LESS THAN THE VALUE THAT YOU ARE ENTITLED TO
RECEIVE UNDER THE TERMS OF THE MERGER AGREEMENT.

         Costs of the appraisal proceeding may be imposed upon the surviving
corporation and the stockholders participating in the appraisal proceeding by
the Chancery Court as the Chancery Court deems equitable in the circumstances.
Upon the application of a stockholder, the Chancery Court may order all or a
portion of the expenses incurred by any stockholder in connection with the
appraisal proceeding, including, without limitation, reasonable attorneys' fees
and the fees and expenses of experts, to be charged pro rata against the value
of all shares entitled to appraisal. Any stockholder who had demanded appraisal
rights will not, after the effective time, be entitled to vote shares subject to
that demand for any purpose or to receive payments of dividends or any other
distribution with respect to those shares, other than with respect to payment as
of a record date prior to the effective time; however, if no petition for
appraisal is filed within 120 days after the effective time of the merger, or if
the stockholder delivers a written withdrawal of the stockholder's demand for
appraisal and an acceptance of the terms of the merger within 60 days after the
effective time of the merger, then the right of that stockholder to appraisal
will cease and that stockholder will be entitled to receive the cash payment for
shares of his, her or its Excel Technology common stock pursuant to the merger
agreement. Any withdrawal of a demand for appraisal made more than 60 days after
the effective time of the merger may only be made with the written approval of
the surviving corporation. Once a petition for appraisal has been filed, the
appraisal proceeding may not be dismissed as to any stockholder without the
approval of the Chancery Court.

         Failure to comply with all of the procedures set forth in Section 262
will result in the loss of a stockholder's statutory appraisal rights. IN VIEW
OF THE COMPLEXITY OF SECTION 262, STOCKHOLDERS WHO MAY WISH TO DISSENT FROM THE
MERGER AND PURSUE APPRAISAL RIGHTS SHOULD CONSULT THEIR LEGAL ADVISORS.

                    MULTIPLE STOCKHOLDERS SHARING ONE ADDRESS

         In accordance with Rule 14a-3(e)(1) under the Exchange Act, one proxy
statement will be delivered to two or more stockholders who share an address,
unless we have received contrary instructions from one or more of the
stockholders. We will deliver promptly upon written or oral request a separate
copy of the proxy statement to a stockholder at a shared address to which a
single copy of the proxy statement was delivered. Requests for additional copies
of the proxy statement, and requests that in the future separate proxy
statements be sent to stockholders who share an address, should be directed to
Excel Technology, Inc., 41 Research Way, East Setauket, NY 11733, Attention:
Investor Relations, telephone: (631) 784-6100. In addition, stockholders who
share a single address but receive multiple copies of the proxy statement may
request that in the future they receive a single copy by contacting us at the
address and phone number set forth in the prior sentence.

                          FUTURE STOCKHOLDER PROPOSALS

         If the merger is completed, we will not hold a 2006 annual meeting of
stockholders. If the merger is not completed, you will continue to be entitled
to attend and participate in our stockholder meetings and we will hold a 2006
annual meeting of stockholders. To be eligible for consideration for inclusion
in the proxy statement and form of proxy for our 2006 annual meeting of
stockholders in accordance with Rule 14a-8 under the Securities Exchange Act of
1934, as amended, a stockholder proposal must have been received by November 7,
2005.

         Stockholders who did not submit a proposal for inclusion in the Proxy
Statement, as described in the previous paragraph, but who intended to present a
proposal, nomination for director or other business for consideration at a 2006
annual meeting, were required to notify our Corporate Secretary of their
proposal, nomination or other business by no later than January 31, 2006.

                                       39


                                  OTHER MATTERS

         At this time, we know of no other matters to be submitted at the
special meeting. If any other matters properly come before the special meeting,
it is the intention of the persons named in the enclosed proxy card to vote the
shares they represent as our board of directors may recommend.

         It is important that your shares be represented at the special meeting,
regardless of the number of shares which you hold. Therefore, we urge you to
complete, sign, date and return the accompanying proxy card as promptly as

                          AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER (this "AGREEMENT") is made and entered into as
of February 20, 2006, by and among Coherent, Inc., a Delaware corporation
("PARENT"), Spider Acquisition Corporation, a Delaware corporation and direct
wholly-owned subsidiary of Parent ("MERGER SUB"), and Excel Technology, Inc., a
Delaware corporation (the "COMPANY").

                                    RECITALS

     A.   The respective Boards of Directors of Parent, Merger Sub and the
Company have deemed it advisable and in the best interests of their respective
corporations and stockholders that Parent and the Company consummate the
business combination and other transactions provided for herein in order to
advance their respective long-term strategic business interests.

     B.   The respective Boards of Directors of Parent, Merger Sub and the
Company have approved, in accordance with applicable provisions of the laws of
the state of Delaware ("DELAWARE LAW"), this Agreement and the transactions
contemplated hereby, including the Merger.

     C.   The Board of Directors of the Company has resolved to recommend to its
stockholders approval and adoption of this Agreement and approval of the Merger.

     D.   Parent, as the sole stockholder of Merger Sub, has approved and
adopted this Agreement and approved the Merger.

     E.   Parent, Merger Sub and the Company desire to make certain
representations, warranties and agreements in connection with the Merger and
also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the covenants, promises and representations
set forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

                                   ARTICLE I
                                   THE MERGER

     1.1  THE MERGER. At the Effective Time and subject to and upon the terms
and conditions of this Agreement and the applicable provisions of Delaware Law,
Merger Sub shall be merged with and into the Company (the "MERGER"), the
separate corporate existence of Merger Sub shall cease



and the Company shall continue as the surviving corporation. The Company, as the
surviving corporation after the Merger, is hereinafter sometimes referred to as
the "SURVIVING CORPORATION."

     1.2  EFFECTIVE TIME; CLOSING. Subject to the provisions of this Agreement,
the parties hereto shall cause the Merger to be consummated by filing a
Certificate of Merger with the Secretary of State of the State of Delaware in
accordance with the relevant provisions of Delaware Law (the "CERTIFICATE OF
MERGER") (the time of such filing with the Secretary of State of the State of
Delaware or such later time as may be agreed in writing by the Company and
Parent and specified in the Certificate of Merger being the "EFFECTIVE TIME") on
the Closing Date. The closing of the Merger (the "CLOSING") shall take place at
the offices of Wilson Sonsini Goodrich & Rosati, Professional Corporation,
located at 650 Page Mill Road, Palo Alto, California, at a time and date to be
specified by the parties, which shall be no later than the second business day
after the satisfaction or waiver of the conditions set forth in Article VI
(other than those conditions that by their terms are to be satisfied or waived
at the Closing, but subject to the satisfaction or waiver thereof), or at such
other time, date and location as the parties hereto agree in writing; PROVIDED,
HOWEVER, that if all the conditions set forth in Article VI shall not have been
satisfied or waived on such second business day, then the Closing shall take
place on the first business day on which all such conditions shall have been
satisfied or waived. The date on which the Closing occurs is referred to herein
as the "CLOSING DATE."

     1.3  EFFECT OF THE MERGER. At the Effective Time, the effect of the Merger
shall be as provided in this Agreement and the applicable provisions of Delaware
Law, including Section 259 of the General Corporation Law of the State of
Delaware. Without limiting the generality of the foregoing, and subject thereto,
at the Effective Time all the property, rights, privileges, powers and
franchises of the Company and Merger Sub shall vest in the Surviving
Corporation, and all debts, liabilities and duties of the Company and Merger Sub
shall become the debts, liabilities and duties of the Surviving Corporation.

     1.4  CERTIFICATE OF INCORPORATION AND BYLAWS. At the Effective Time, the
Certificate of Incorporation of the Surviving Corporation shall be amended and
restated to read the same as the Certificate of Incorporation of Merger Sub, as
in effect immediately prior to the Effective Time, until thereafter amended in
accordance with Delaware Law and as provided in such Certificate of
Incorporation; PROVIDED, HOWEVER, that at the Effective Time, Article I of the
Certificate of Incorporation of the Surviving Corporation shall be amended and
restated in its entirety to read as follows: "The name of the corporation is
Excel Technology, Inc." and, to the extent necessary, the Certificate of
Incorporation shall be amended so as to comply with Section 5.10(a). At the
Effective Time, the Bylaws of the Surviving Corporation shall be amended and
restated to read the same as the Bylaws of Merger Sub, as in effect immediately
prior to the Effective Time, until thereafter amended in accordance with
Delaware Law and as provided in such Bylaws; PROVIDED, HOWEVER, that at the

                                      A-2


Effective Time, the Bylaws shall be amended, to the extent necessary, so as to
comply with Section 5.10(a).

     1.5  DIRECTORS AND OFFICERS. The initial directors of the Surviving
Corporation shall be the directors of Merger Sub immediately prior to the
Effective Time, until their respective successors are duly elected or appointed
and qualified. The initial officers of the Surviving Corporation shall be the
officers of Merger Sub immediately prior to the Effective Time, until their
respective successors are duly appointed.

     1.6  EFFECT ON CAPITAL STOCK. Subject to the terms and conditions of this
Agreement, at the Effective Time, by virtue of the Merger and without any action
on the part of Parent, Merger Sub, the Company or the holders of any shares of
capital stock of the Company, the following shall occur:

          (a)  COMPANY COMMON STOCK. Each share of the Common Stock, par value
$0.001 per share, of the Company ("COMPANY COMMON STOCK") issued and outstanding
immediately prior to the Effective Time, other than any shares of Company Common
Stock to be canceled pursuant to Section 1.6(c) and any Dissenting Shares, will
be canceled and extinguished and automatically converted (subject to Section
1.6(f)) into the right to receive $30.00 in cash, without interest (as may be
adjusted, the "PER SHARE AMOUNT" and the sum of the Per Share Amounts, the
"MERGER CONSIDERATION"), upon surrender of the certificate representing such
share of Company Common Stock in the manner provided in Section 1.7 (or in the
case of a lost, stolen or destroyed certificate, upon delivery of an affidavit
(and bond, if required) in the manner provided in Section 1.9).

          (b)  REPURCHASE RIGHTS. If any shares of Company Common Stock
outstanding immediately prior to the Effective Time are unvested or are subject
to a repurchase option, risk of forfeiture or other condition under any
applicable restricted stock purchase agreement or other agreement with the
Company ("COMPANY RESTRICTED STOCK"), then the portion of the Merger
Consideration payable in exchange for such shares of Company Common Stock will
also be unvested and subject to the same repurchase option, risk of forfeiture
or other condition. The Company shall take all action that may be necessary to
ensure that, from and after the Effective Time, the Surviving Corporation is
entitled to exercise any such repurchase option or other right set forth in any
such restricted stock purchase agreement or other agreement. The portion of the
Merger Consideration payable upon conversion of the Company Restricted Stock
shall be withheld and paid by the Merger Sub to such holder in accordance with
the vesting and other provisions set forth in the applicable restricted stock
purchase agreement or other agreement.

          (c)  CANCELLATION OF TREASURY AND PARENT OWNED STOCK. Each share of
Company Common Stock held by the Company or Parent or any direct or indirect
wholly-owned Subsidiary of the Company or of Parent immediately prior to the
Effective Time shall be canceled and extinguished without any conversion
thereof.

                                      A-3


          (d)  CAPITAL STOCK OF MERGER SUB. Each share of common stock, par
value $0.001, of Merger Sub (the "MERGER SUB COMMON STOCK") issued and
outstanding immediately prior to the Effective Time shall evidence ownership of
such shares of capital stock of the Surviving Corporation.

          (e)  STOCK OPTIONS. At the Effective Time, no outstanding Company
Options will be assumed by Parent, and unless otherwise exercised by the holder
thereof or purchased by the Company under Section 5.17, any outstanding Company
Options shall terminate on the Effective Time in accordance with their terms.

          (f)  ADJUSTMENTS TO PER SHARE AMOUNT. The Per Share Amount shall be
adjusted to reflect fully the appropriate effect of any stock split, reverse
stock split, stock dividend (including any dividend or distribution of
securities convertible into Company Common Stock), reorganization,
recapitalization, reclassification or other like change with respect to Company
Common Stock having a record date on or after the date hereof and prior to the
Effective Time.

          1.7  SURRENDER OF CERTIFICATES.

               (a)  PAYMENT AGENT. Parent shall select an institution to act as
the payment agent (the "PAYMENT AGENT") for the Merger.

               (b)  PARENT TO PROVIDE CASH. On or before the Effective Time,
Parent shall make available to the Payment Agent for exchange in accordance with
this Article I, the Merger Consideration deliverable pursuant to Section 1.6(a)
in exchange for the outstanding shares of Company Common Stock. Any cash
deposited with the Payment Agent shall hereinafter be referred to as the
"EXCHANGE FUND."

               (c)  EXCHANGE PROCEDURES. As promptly as reasonably practicable
after the Effective Time, Parent shall cause the Payment Agent to mail to each
holder of record (as of the Effective Time) of a certificate or certificates
(the "CERTIFICATES") which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock whose shares were converted into the
right to receive a portion of the Merger Consideration pursuant to Section
1.6(a): (i) 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
delivery of the Certificates to the Payment Agent and shall be in such form and
have such other provisions as Parent may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for a portion of the Merger Consideration. Upon surrender of Certificates for
cancellation to the Payment Agent or to such other agent or agents as may be
appointed by Parent, together with such letter of transmittal, duly completed
and validly executed in accordance with the instructions thereto and such other
documents as may reasonably be required by the Payment Agent, the holder of
record of such Certificates shall be entitled to receive in exchange therefor
the portion of the Merger Consideration

                                      A-4


(after taking into account all Certificates surrendered by such holder of
record) to which such holder is entitled pursuant to Section 1.6(a), and the
Certificates so surrendered shall forthwith be canceled. Until so surrendered,
outstanding Certificates will be deemed from and after the Effective Time, for
all corporate purposes, to evidence the ownership of the portion of the Merger
Consideration for which such shares of Company Common Stock shall have been so
converted.

               (d)  REQUIRED WITHHOLDING. Each of the Payment Agent and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Company Common Stock such amounts as may be required
to be deducted or withheld therefrom under the Code or under any provision of
state, local or foreign Tax law or under any other applicable Legal Requirement.
To the extent such amounts are so deducted or withheld, the amount of such
consideration shall be treated for all purposes under this Agreement as having
been paid to the Person to whom such consideration would otherwise have been
paid.

               (e)  NO LIABILITY. Notwithstanding anything to the contrary in
this Section 1.7, neither the Payment Agent, the Surviving Corporation nor any
party hereto shall be liable to a holder of shares of Company Common Stock for
any amount paid to a public official pursuant to any applicable abandoned
property, escheat or similar law.

               (f)  INVESTMENT OF EXCHANGE FUND. The Payment Agent shall invest
the cash included in the Exchange Fund as directed by Parent on a daily basis;
PROVIDED that no such investment or loss thereon shall affect the amounts
payable to Company stockholders pursuant to this Article I. Any interest and
other income resulting from such investment shall become a part of the Exchange
Fund, and any amounts in excess of the amounts payable to Company stockholders
pursuant to this Article I shall promptly be paid to Parent.

               (g)  TERMINATION OF EXCHANGE FUND. Any portion of the Exchange
Fund which remains undistributed to the holders of Certificates nine (9) months
after the Effective Time shall, at the request of Parent or the Surviving
Corporation, be delivered to the Surviving Corporation or Parent or otherwise
according to the instruction of the Surviving Corporation or Parent, and any
holders of the Certificates who have not surrendered such Certificates in
compliance with this Section 1.7 shall after such delivery to Surviving
Corporation look only to Parent or the Surviving Corporation for the portion of
the Merger Consideration deliverable pursuant to Section 1.6(a) with respect to
the shares of Company Common Stock formerly represented thereby. If any
Certificate shall not have been surrendered prior to two (2) years after the
Effective Time (or immediately prior to such time as such amounts would
otherwise escheat to or become property of any Governmental Entity), any such
portion of the Exchange Fund remaining unclaimed by holders of shares of Company
Common Stock immediately prior to such time shall, to the extent permitted by
law,

                                      A-5


become the property of Parent free and clear of any claims or interest of any
Person previously entitled thereto.

     1.8  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK. The Merger
Consideration paid upon the surrender for exchange of shares of Company Common
Stock in accordance with the terms hereof shall be deemed to have been paid in
full satisfaction of all rights pertaining to such shares of Company Common
Stock, and there shall be no further registration of transfers on the records of
the Surviving Corporation of shares of Company Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article I.

     1.9  LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any Certificates
shall have been lost, stolen or destroyed, the Payment Agent shall deliver in
exchange for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, the portion of the Merger
Consideration to which the holder thereof would have been entitled upon the
delivery of such Certificate; PROVIDED, HOWEVER, that Parent or the Payment
Agent may, in their sole discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed Certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against Parent, the Company or the Payment Agent with
respect to the Certificates alleged to have been lost, stolen or destroyed.

     1.10 DISSENTING SHARES. Notwithstanding anything in this Agreement to the
contrary, shares of Company Common Stock which are issued and outstanding
immediately prior to the Effective Time and which are held by stockholders
properly exercising appraisal rights (the "DISSENTING SHARES") available under
Section 262 ("SECTION 262") of Delaware Law shall not be converted into or be
exchangeable for the right to receive the portion of the Merger Consideration
for which such shares of Company Common Stock would otherwise have been
entitled, unless and until such holders shall have failed to perfect or shall
have effectively withdrawn or lost their rights to appraisal under Section 262.
If any such holder shall have failed to perfect or shall have effectively
withdrawn or lost such right to appraisal, such holder's shares of Company
Common Stock shall thereupon be converted into and be exchangeable only for the
right to receive, as of the Effective Time, the portion of the Merger
Consideration to which such holder would have been entitled pursuant to this
Article I for such shares of Company Common Stock. The Company shall give Parent
and Merger Sub (a) prompt notice of any written demands for appraisal of any
shares of Company Common Stock, attempted withdrawals of such demands and any
other instruments served pursuant to Delaware Law and received by the Company
relating to rights to be paid the "fair value" of Dissenting Shares, as provided
in Section 262 and (b) the opportunity to participate in, and after the Closing,
direct all negotiations and proceedings with respect to demands for appraisal
under Section 262. The Company

                                      A-6


shall not, except with the prior written consent of Parent, voluntarily make or

jurisdiction in which the nature of its business or the ownership or leasing of
its properties makes such qualification or licensing necessary, other than in
such jurisdictions where the failure to so qualify or to be in good standing,

Material Adverse Effect on the Company. For purposes of this Agreement,
"SUBSIDIARY," when used with respect to any party, shall mean any corporation or
other organization, whether incorporated or unincorporated, at least a majority

Company, each as amended to date (collectively, the "COMPANY CHARTER DOCUMENTS")

bylaws, or like organizational documents (collectively, "SUBSIDIARY CHARTER
DOCUMENTS"), of each of its Subsidiaries, and each such instrument is in full
force and effect. The Company is not in violation of any of the provisions of

local, municipal, foreign or other law, statute, constitution, principle of
common law, resolution, ordinance, code, order, edict, decree, rule, regulation,

     2.3  AUTHORITY; NON-CONTRAVENTION; NECESSARY CONSENTS.

          (a)  AUTHORITY. The Company has all requisite corporate power and
authority to enter into this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby has been duly authorized by
all necessary corporate action on the part of the Company and no other

                                      A-10


corporate proceedings on the part of the Company are necessary to authorize the
execution and delivery of this Agreement or to consummate the Merger and the
other transactions contemplated hereby, subject only to the approval and
adoption of this Agreement and the approval of the Merger by the Company's
stockholders and the filing of the Certificate of Merger pursuant to Delaware
Law. The affirmative vote of the holders of a majority of the outstanding shares
of Company Common Stock to approve and adopt this Agreement and approve the
Merger is the only vote of the holders of any class or series of Company capital
stock necessary to approve and adopt this Agreement, approve the Merger and
consummate the Merger and the other transactions contemplated hereby (the
"COMPANY STOCKHOLDER APPROVAL"). This Agreement has been duly executed and
delivered by the Company and, assuming due execution and delivery by Parent and
Merger Sub, constitute valid and binding obligations of the Company, enforceable
against the Company in accordance with their terms.

          (b)  NON-CONTRAVENTION. The execution and delivery of this Agreement
by the Company does not, and performance of this Agreement by the Company will
not: (i) conflict with or violate the Company Charter Documents or any
Subsidiary Charter Documents, (ii) subject to obtaining the approval and
adoption of this Agreement and the approval of the Merger by the Company's
stockholders as contemplated in Section 5.2 and compliance with the requirements
set forth in Section 2.3(c), conflict with or violate any material Legal
Requirement applicable to the Company or any of its Subsidiaries or by which the
Company or any of its Subsidiaries or any of their respective properties is
bound or affected, or (iii) result in any breach of or constitute a default (or
an event that with notice or lapse of time or both would become a default)
under, or materially impair the Company's rights or alter the rights or
obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a Lien on any of the properties or assets of the Company or any of
its Subsidiaries pursuant to, any Company Material Contract. Section 2.3(b) of
the Company Disclosure Letter lists all consents, waivers and approvals under
any of the Company's or any of its Subsidiaries' Contracts required to be
obtained in connection with the consummation of the transactions contemplated
hereby, which, if individually or in the aggregate were not obtained, would
result in a material loss of benefits to the Company, Parent or the Surviving
Corporation as a result of the Merger.

          (c)  NECESSARY CONSENTS. No consent, approval, order or authorization
of, or registration, declaration or filing with any supranational, national,
state, municipal, local or foreign government, any instrumentality, subdivision,
court, administrative agency or commission or other governmental authority or
instrumentality, or any quasi-governmental or private body exercising any
regulatory, taxing, importing or other governmental or quasi-governmental

obtained or made by the Company in connection with the execution and delivery of
this Agreement or the consummation of the Merger and other transactions
contemplated hereby, except for: (i) the filing of the Certificate of Merger

and state securities (or related) laws and the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR ACT") and satisfaction of such
other requirements of the comparable laws of other jurisdictions that the Parent
reasonably determines to apply, and (iv) such other consents, authorizations,
filings, approvals and registrations which if not obtained or made would not be
material to the Company, Parent or Merger Sub or materially adversely affect the
ability of the parties hereto to consummate the Merger within the time frame in
which the Merger would otherwise be consummated in the absence of the need for
such consent, approval, order, authorization, registration, declaration or
filings. The consents, approvals, orders, authorizations, registrations,
declarations and filings set forth in (i) through (iv) are referred to herein as
the "NECESSARY CONSENTS."

     2.4  SEC FILINGS; FINANCIAL STATEMENTS; CONTROLS.

          (a)  SEC FILINGS. The Company has filed all required registration
statements, prospectuses, reports, schedules, forms, statements and other
documents (including exhibits and all other information incorporated by
reference) required to be filed by it with the SEC since December 31, 2001. All
such required registration statements, prospectuses, reports, schedules, forms,
statements and other documents (including those that the Company may file
subsequent to the date hereof) are referred to herein as the "COMPANY SEC
REPORTS." As of their respective dates, the Company SEC Reports (i) were
prepared in accordance and complied in all material respects with the
requirements of the Securities Act of 1933, as amended (the "SECURITIES ACT"),
or the Exchange Act, as the case may be, and the rules and regulations of the
SEC thereunder applicable to such Company SEC Reports and (ii) did not at the
time they were filed (or if amended or superseded by a filing prior to the date
of this Agreement then on the date of such filing) contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading. None of the
Company's Subsidiaries is required to file any forms, reports or other documents
with the SEC. The Company has previously furnished to Parent a complete and
correct copy of any amendments or modifications, which have not yet been filed
with the SEC but which are required to be filed, to agreements, documents or
other instruments which previously had been filed by Company with the SEC
pursuant to the Securities Act or the Exchange Act.

          (b)  FINANCIAL STATEMENTS. Each of the consolidated financial
statements (including, in each case, any related notes thereto) contained in the
Company SEC Reports (the "COMPANY FINANCIALS"), including each Company SEC
Report filed after the date hereof until the Closing:

                                      A-12


(i) complied as to form in all material respects with the published rules and
regulations of the SEC with respect thereto, (ii) was prepared in accordance
with United States generally accepted accounting principles ("GAAP") applied on
a consistent basis throughout the periods involved (except as may be indicated
in the notes thereto or, in the case of unaudited interim financial statements,
as may be permitted by the SEC on Form 10-Q, 8-K or any successor form under the
Exchange Act), and (iii) fairly presented in all material respects the
consolidated financial position of the Company and its consolidated Subsidiaries
as at the respective dates thereof and the consolidated results of the Company
operations and cash flows for the periods indicated. The Company does not intend
to correct or restate, nor is there any basis for any correction or restatement
of, any aspect of the Company Financials. The balance sheet of the Company
contained in the Company SEC Reports as of September 30, 2005 is hereinafter
referred to as the "COMPANY BALANCE SHEET." Except as disclosed in the Company
Financials, since the date of the Company Balance Sheet, neither the Company nor
any of its Subsidiaries has any liabilities (absolute, accrued, contingent or
otherwise) of a nature required to be disclosed on a consolidated balance sheet
or in the related notes to the consolidated financial statement prepared in
accordance with GAAP which are, individually or in the aggregate, material to
the business, results of operations or financial condition of the Company and
its Subsidiaries taken as a whole.

          (c)  DISCLOSURE CONTROLS AND PROCEDURES. The Company has established
and maintains disclosure controls and procedures (as defined in Rule 13a-15
under the Exchange Act). Such disclosure controls and procedures are designed to
ensure that material information relating to the Company, including its
Subsidiaries, is made known to the Company's principal executive officer and its
principal financial officer by others within those entities. To the knowledge of
the Company, based on its evaluation of the Company's disclosure controls and
procedures as of the end of the Company's most recently completed fiscal
quarter, such disclosure controls and procedures are currently effective in
timely alerting the Company's principal executive officer and principal
financial officer to material information required to be included in the
Company's periodic and current reports required under the Exchange Act.

          (d)  INTERNAL CONTROL OVER FINANCIAL REPORTING. The Company has
established and maintains a system of internal control over financial reporting
(as defined in Rule 13a-15 under the Exchange Act). Based on its evaluation of
its internal control over financial reporting as of the end of the Company's
most recently completed fiscal quarter, such internal control over financial
reporting is sufficient to provide reasonable assurance regarding the
reliability of the Company's financial reporting and the preparation of the
Company's financial statements for external purposes in accordance with GAAP.
Based on its most recent evaluation of internal control over financial reporting
and, to the knowledge of the Company, since such evaluation, there are not any
significant deficiencies or material weaknesses known to the Company in the
design or operation of internal control over financial reporting which could
reasonably be expected to adversely affect in a material

                                      A-13


respect the Company's ability to record, process, summarize and report financial
information or any material fraud known to the Company that involves management
or other employees who have a significant role in internal control over
financial reporting. The Company has furnished to Parent disclosures regarding
material weaknesses, significant deficiencies and fraud involving management or
other employees who have a significant role in internal control over financial
reporting since December 31, 2002.

     2.5  ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as set forth in Section
2.5 of the Company Disclosure Letter, since the date of the Company Balance
Sheet there has not been: (i) any Material Adverse Effect on the Company, (ii)
any declaration, setting aside or payment of any dividend on, or other
distribution (whether in cash, stock or property) in respect of, any of the
Company's or any of its Subsidiaries' capital stock, or any purchase, redemption
or other acquisition by the Company or any of its Subsidiaries of any of the
Company's capital stock or any other securities of the Company or its
Subsidiaries or any options, warrants, calls or rights to acquire any such
shares or other securities except for repurchases from Employees following their
termination pursuant to the terms of their pre-existing stock option or purchase
agreements, (iii) any split, combination or reclassification of any of the
Company's or any of its Subsidiaries' capital stock; (iv) any granting by the
Company or any of its Subsidiaries of any increase in compensation or fringe
benefits, except for normal increases of cash compensation in the ordinary
course of business consistent with past practice (other than to directors or
executive officers of the Company), or any payment by the Company or any of its
Subsidiaries of any bonus, except for bonuses made in the ordinary course of
business consistent with past practice (other than to directors or executive
officers of the Company), or any granting by the Company or any of its
Subsidiaries of any increase in severance or termination pay or any entry by the
Company or any of its Subsidiaries into any currently effective employment,
severance, termination or indemnification agreement or any agreement the
benefits of which are contingent or the terms of which are materially altered
upon the occurrence of a transaction involving the Company of the nature
contemplated hereby, (v) entry by the Company or any of its Subsidiaries into
any licensing or other agreement with regard to the acquisition or disposition
of any material Intellectual Property other than licenses, distribution
agreements, advertising agreements, sponsorship agreements or merchant program
agreements entered into in the ordinary course of business consistent with past
practice, (vi) any amendment with respect to any Company Material Contract in
effect, (vii) any material change by the Company in its accounting methods,
principles or practices, except as required by concurrent changes in GAAP, or
(viii) any material revaluation by the Company of any of its assets, including
writing down the value of capitalized inventory or writing off notes or accounts
receivable other than in the ordinary course of business consistent with past
practice.

in each jurisdiction in which the nature of its business or the ownership or
leasing of its properties makes such qualification necessary, other than in such

     5.1  PROXY STATEMENT.

As promptly as practicable after the execution of this Agreement, the Company
shall prepare, and file with the SEC, the Proxy Statement relating to the
Company Stockholder Approval. Parent shall provide promptly to the Company such
information concerning Parent as, in the reasonable judgment of Parent, the
Company or their respective counsel, may be required or appropriate for
inclusion in the Proxy Statement, or in any amendments or supplements thereto.
At the earliest practicable time following the later of (i) receipt and
resolution of SEC comments thereon, or (ii) the expiration of the 10-day waiting
period provided in Rule 14a-6(a) promulgated under the Exchange Act, the Company
shall file definitive proxy materials with the SEC and cause the Proxy Statement
to be mailed to its stockholders. The Company will use commercially reasonable
efforts to cause all documents that it is responsible for filing with the SEC or
other regulatory authorities in connection with the Merger (or

                                      A-39


as required or appropriate to facilitate the Merger) to comply in all material
respects with all applicable Legal Requirements. Prior to filing the preliminary
proxy materials, definitive proxy materials or any other filing with the SEC,
any other Governmental Entity or other regulatory authorities, the Company shall
provide Parent (which term shall in all instances in this Section 5.1 also
include Parent's counsel) with reasonable opportunity to review and comment on
each such filing in advance and the Company shall in good faith consider
including in such filings all comments reasonably proposed by Parent. The
Company will notify Parent promptly of the receipt of any comments from the SEC
or its staff (or of notice of the SEC's intent to review the Proxy Statement)
and of any request by the SEC or its staff or any other government or regulatory
officials for amendments or supplements to the Proxy Statement or any other
filing or for additional/supplemental information, and will supply Parent with
copies of all correspondence between the Company or any of its representatives,
on the one hand, and the SEC, or its staff or any other government or regulatory
officials, on the other hand, with respect to the Proxy Statement or any such
other filing. The Company and its outside counsel shall permit Parent to
participate in all communications with the SEC and its staff (including all
meetings and telephone conferences) relating to the Proxy Statement, this
Agreement or the Merger. The Company shall consult with Parent prior to
responding to any comments or inquiries by the SEC, any other Governmental
Entity or regulatory authority with respect to any filings related to (or
necessary or appropriate to facilitate) the Merger, shall provide Parent with
reasonable opportunity to review and comment on any such written response in
advance and shall in good faith consider including in such response all comments
reasonably proposed by Parent. Whenever any event occurs that is required to be
set forth in an amendment or supplement to the Proxy Statement or any other
filing, the Company shall promptly inform Parent of such occurrence, provide
Parent with reasonable opportunity to review and comment on any such amendment
or supplement in advance, shall in good faith consider including in such
amendment or supplement all comments reasonably proposed by Parent, and shall
cooperate in filing with the SEC or its staff, any other Governmental Entity or
regulatory authority, and/or mailing to the stockholders of the Company, such
amendment or supplement.

     5.2  MEETING OF COMPANY STOCKHOLDERS; BOARD RECOMMENDATION.

          (a)  MEETING OF COMPANY STOCKHOLDERS. Promptly after the date hereof,
the Company will take all action necessary in accordance with Delaware Law and
its Certificate of Incorporation and Bylaws to call, hold and convene a meeting
of its stockholders to consider adoption and approval of this Agreement and
approval of the Merger (the "STOCKHOLDERS' MEETING"). The Stockholder's Meeting
shall be held as promptly as practicable, and in any event (to the extent
permissible under applicable law) within 45 days after the Proxy Statement is
cleared by the SEC (or if no SEC comments are received on or prior to the
expiration of the 10-day waiting period provided in Rule 14a-6(a) promulgated
under the Exchange Act, within 55 days after such initial filing). Subject to
Section 5.3(d), the Company will use all reasonable efforts to solicit from its
stockholders

                                      A-40


proxies in favor of the adoption and approval of this Agreement and the approval
of the Merger, and will take all other action necessary or advisable to secure
the vote or consent of its stockholders required by the rules of Nasdaq or
Delaware Law to obtain such approvals. Notwithstanding anything to the contrary
contained in this Agreement, the Company may adjourn or postpone the
Stockholders' Meeting to the extent necessary to ensure that any necessary
supplement or amendment to the Proxy Statement is provided to its stockholders
in advance of a vote on the Merger and this Agreement or if, as of the time for
which the Stockholders' Meeting is originally scheduled (as set forth in the
Proxy Statement), there are insufficient shares of Company Common Stock
represented (either in person or by proxy) to constitute a quorum necessary to
conduct the business of such Stockholders' Meeting or there are not sufficient
votes for the adoption of this Agreement and the approval of the Merger. The
Company shall ensure that the Stockholders' Meeting is called, noticed,
convened, held and conducted, and that all proxies solicited by it in connection
with the Stockholders' Meeting are solicited in compliance with Delaware Law,
its Certificate of Incorporation and Bylaws, the rules of Nasdaq and all other
applicable Legal Requirements.

recommend that its stockholders vote in favor of adoption and approval of this
Agreement and approval of the Merger at the Stockholders' Meeting, (ii) the
Proxy Statement shall include a statement to the effect that the Board of
Directors of the Company has unanimously recommended that the Company's
stockholders vote in favor of adoption and approval of this Agreement and
approval of the Merger at the Stockholders' Meeting, and (iii) neither the Board
of Directors of the Company nor any committee thereof shall withdraw, amend or
modify, or propose or resolve to withdraw, amend or modify, in a manner adverse
to Parent and Merger Sub, the unanimous recommendation of its Board of Directors
that the Company's stockholders vote in favor of adoption and approval of this
Agreement and the Merger. Without limitation, the recommendation of the Board of
Directors of the Company shall be deemed to have been modified in a manner
adverse to Parent if the recommendation shall no longer be unanimous.

     5.3  ACQUISITION PROPOSALS.

          (a)  NO SOLICITATION. Except to the extent expressly permitted by
Section 5.3(c), the Company agrees that neither it nor any of its Subsidiaries,
nor any of the officers and directors of it or its Subsidiaries shall, and that
it shall not permit its and its Subsidiaries' Employees, agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its Subsidiaries) to, directly or indirectly: (i)
solicit, initiate, encourage, knowingly facilitate or induce any inquiry with
respect to, or the making, submission or announcement of, any Acquisition
Proposal, (ii) participate in any discussions or negotiations regarding, or
furnish to any Person any nonpublic information with respect to, or take any
other action to facilitate any inquiries or the

                                      A-41


making of any proposal that constitutes or may reasonably be expected to lead
to, any Acquisition Proposal, (iii) engage in discussions with any Person with
respect to any Acquisition Proposal, except as to the existence of these
provisions, (iv) approve, endorse or recommend any Acquisition Proposal (except
to the extent specifically permitted pursuant to Section 5.3(d)), (v) release

Company is a party (or its investment banker on behalf of the Company), or fail
to enforce or grant any material waiver, consent or request to, any Acquisition
Proposal, under such agreement, or (vi) enter into any letter of intent or
similar document or any contract agreement or commitment contemplating or
otherwise relating to any Acquisition Proposal or transaction contemplated
thereby. The Company and its Subsidiaries will immediately cease any and all
existing activities, discussions or negotiations with any third parties
conducted heretofore with respect to any Acquisition Proposal. The Company
acknowledges that any violation of the restrictions set forth in this Section
5.3(a) by any officer, director, employee, representative, investment banker,
attorney, accountant or agent of the Company or any of its Subsidiaries shall be
deemed to be a breach of this Section 5.3(a) by the Company.

          (b)  NOTIFICATION OF UNSOLICITED ACQUISITION PROPOSALS.

               (i)  As time is of the essence, as promptly as practicable (and
in any event no later than 24 hours) after receipt of any Acquisition Proposal
or any request for nonpublic information or inquiry which it reasonably believes
would lead to an Acquisition Proposal, the Company shall provide Parent with
oral and written notice of the material terms and conditions of such Acquisition
Proposal, request or inquiry, and the identity of the Person or group making any
such Acquisition Proposal, request or inquiry and a copy of all written
materials provided in connection with such Acquisition Proposal, request or
inquiry.

               (ii) As time is of the essence, the Company shall provide Parent

Board of Directors at which its Board of Directors is reasonably expected to
consider any Acquisition Proposal.

          (c)  SUPERIOR OFFERS. Notwithstanding anything to the contrary
contained in Section 5.3(a), in the event that the Company receives an
unsolicited, bona fide written Acquisition Proposal from a third party that its
Board of Directors has in good faith concluded (following consultation with its
outside legal counsel and its financial advisor), is, or is reasonably likely to
result in, a Superior Offer, the Company may then take the following actions
(but only if and to the extent that the Board of Directors of the Company
concludes in good faith, following the receipt of advice of the Company's
outside legal counsel, that the failure to do so is reasonably likely to result
in a breach of its fiduciary obligations under applicable Legal Requirements):

                                      A-42


               (i)  Furnish nonpublic information to the third party making such

hours written notice of its intention to furnish such nonpublic information and
(2) the Company receives from the third party an executed confidentiality
agreement containing customary limitations on the use and disclosure of all
nonpublic written and oral information furnished to such third party on the
Company's behalf, the terms of which are at least as restrictive as the terms
contained in the Confidentiality Agreement and (B) contemporaneously with
furnishing any such nonpublic information to such third party, the Company
furnishes such nonpublic information to Parent (to the extent such nonpublic
information has not been previously so furnished); and

               (ii) Engage in negotiations with the third party with respect to
the Acquisition Proposal, PROVIDED that no less than 24 hours prior to entering
into negotiations with such third party, the Company gives Parent written notice
of the Company's intention to enter into negotiations with such third party.

          (d)  CHANGE OF RECOMMENDATION. In response to the receipt of a
Superior Offer, the Board of Directors of the Company may withhold, withdraw,
amend or modify its unanimous recommendation in favor of the Merger and enter
into a written agreement memorializing such Superior Proposal, and, in the case
of a Superior Offer that is a tender or exchange offer made directly to the
stockholders of the Company, may recommend that the stockholders of the Company
accept the tender or exchange offer (any of the foregoing actions, whether by
the Board of Directors of the Company or a committee thereof, a "CHANGE OF
RECOMMENDATION"), only if all of the following conditions in clauses (i) through
(viii) are met:

               (i)  A Superior Offer with respect to it has been made and has
not been withdrawn;

               (ii) The Stockholders' Meeting has not occurred;

               (iii) The Company shall have (A) provided to Parent written
notice which shall state expressly (1) that the Company has received a Superior

such Superior Offer, and (C) made available to Parent all other materials and
information made available to the Person or group making the Superior Offer in
connection with such Superior Offer;

                                      A-43


               (iv) The Board of Directors of the Company has concluded in good
faith, after receipt of advice of its outside legal counsel, that, in light of
such Superior Offer, the failure of the Board of Directors to effect a Change of
Recommendation is reasonably likely to result in a breach of its fiduciary
obligations to the stockholders of the Company under applicable law;

               (v)  The Company shall not have breached any of the provisions
set forth in Section 5.2 or this Section 5.3;

               (vi) At least two (2) business days shall have elapsed from the

specified in Section 5.3(d)(vi), the Board of Directors of the Company does not
conclude in good faith (after consultation with its outside legal counsel and
its financial advisor) that such Acquisition Proposal no longer constitutes a
Superior Offer.

          (e)  CONTINUING OBLIGATION TO CALL, HOLD AND CONVENE STOCKHOLDERS'
MEETING; NO OTHER VOTE. Notwithstanding anything to the contrary contained in
this Agreement, unless this Agreement is earlier terminated pursuant to Section
7.1, the obligation of the Company to call, give notice of, convene and hold the
Stockholders' Meeting shall not be limited or otherwise affected by the
commencement, disclosure, announcement or submission to it of any Acquisition
Proposal, or by any Change of Recommendation and, the Company shall not submit
to the vote of its stockholders any Acquisition Proposal, or propose to do so.

          (f)  COMPLIANCE WITH TENDER OFFER RULES. Nothing contained in this
Agreement shall prohibit the Company or its Board of Directors from taking and
disclosing to the stockholders of the Company a position contemplated by Rules
14d-9 and 14e-2(a) promulgated under the Exchange Act; PROVIDED that the content
of any such disclosure thereunder shall be governed by the terms of this
Agreement. Without limiting the foregoing proviso, the Company shall not effect
a Change of Recommendation unless specifically permitted pursuant to the terms
of Section 5.3(d).

purchase from such party or acquisition by any PERSON or "group" (as defined

thereunder) of more than a ten percent (10%) interest in the total outstanding
voting securities of the Company or any of its Subsidiaries or any tender offer
or exchange offer that if consummated would result in any Person or group

transaction would hold less than fifty percent (50%) of the equity interests in
the surviving or resulting entity of such transaction or any direct or indirect
parent or subsidiary thereof, on terms that the Board of Directors of the
Company has in good faith concluded (following consultation with its outside

Person making the offer (including committed borrowing capacity to the extent
necessary to finance such Acquisition Proposal), to be more favorable, from a
financial point of view, to the Company's stockholders (in their capacities as
stockholders) than the terms of the Merger (taking into account all of the terms

Merger) and is reasonably capable of being consummated without unreasonable
delay.

performing such environmental tests and investigations as Parent may desire);
PROVIDED, HOWEVER, that the Company may restrict the foregoing access to the
extent that any law, treaty, rule or regulation of any Governmental Entity
applicable to such party requires such party or its Subsidiaries to restrict or
prohibit access to any such properties or information.

          (c)  NO MODIFICATION OF REPRESENTATIONS AND WARRANTIES OR COVENANTS.

                                      A-47


occurs that is required to be set forth in an amendment or supplement to any
filing made pursuant to Section 5.6(a), Parent, Merger Sub or the Company, as
the case may be, will promptly inform the other of such occurrence and cooperate
in filing with the applicable Governmental Entity such amendment or supplement.

          (d)  COMMERCIALLY REASONABLE EFFORTS. Subject to the express
provisions of Section 5.2 and Section 5.3 hereof and upon the terms and subject
to the conditions set forth herein, each of the parties agrees to use
commercially reasonable 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 using commercially
reasonable efforts to accomplish the following: (i) the taking of commercially
reasonable acts necessary to cause the conditions precedent set forth in Article
VI to be satisfied, (ii) the obtaining of all necessary actions or nonactions,
waivers, consents, approvals, orders and authorizations from Governmental
Entities and the making of all necessary registrations, declarations and filings
(including registrations, declarations and filings with Governmental Entities,
if any) and the taking of all reasonable steps as may be necessary to avoid any
suit, claim, action, investigation or proceeding by any Governmental Entity,
(iii) the obtaining of all necessary consents, approvals or waivers from third
parties, including all Necessary Consents, (iv) the defending of any suits,
claims, actions, investigations or proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of the
transactions contemplated hereby and (v) the execution or delivery of any
additional instruments necessary to consummate the transactions contemplated by,
and to fully carry out the purposes of, this Agreement. In connection with and
without limiting the foregoing, the Company and its Board of Directors shall, if
any takeover statute or similar Legal Requirement is or becomes applicable to
the Merger, this Agreement or any of the transactions contemplated by this
Agreement, use all reasonable efforts to ensure that the Merger and the other
transactions contemplated by this Agreement may be consummated as promptly as
practicable on the terms contemplated by this Agreement and otherwise to
minimize the effect of such Legal Requirement on the Merger, this Agreement and
the transactions contemplated hereby.

          (e)  LIMITATION ON DIVESTITURE. Notwithstanding anything in this
Agreement to the contrary, nothing contained in this Agreement shall be deemed
to require Parent or the Company or any Subsidiary or affiliate thereof to agree
to any Action of Divestiture. The Company shall not take or agree to take any
Action of Divestiture without the prior written consent of Parent. For purposes
of this agreement, an "ACTION OF DIVESTITURE" shall mean any divestiture by
Parent or the Company or any of their Subsidiaries or affiliates of shares of
capital stock or of any business, assets or property, or the imposition of any
material limitation on the ability of any of them to conduct their businesses or
to own or exercise control of such assets, properties and stock.

                                      A-48


     5.7  NOTIFICATION OF CERTAIN MATTERS.

          (a)  BY THE COMPANY. The Company shall give prompt notice to Parent
and Merger Sub of any representation or warranty made by it contained in this
Agreement becoming untrue or inaccurate, or any failure of the Company to comply
with or satisfy in any material respect any covenant, condition or agreement to
be complied with or satisfied by it under this Agreement, in each case, such
that the conditions set forth in Section 6.3(a) or 6.3(b) would not be
satisfied.

          (b)  BY PARENT. Parent and Merger Sub shall give prompt notice to the
Company of any representation or warranty made by it contained in this Agreement
becoming untrue or inaccurate, or any failure of Parent to comply with or
satisfy in any material respect any covenant, condition or agreement to be
complied with or satisfied by it under this Agreement, in each case, such that
the conditions set forth in Section 6.2(a) or 6.2(b) would not be satisfied. 5.8
THIRD-PARTY CONSENTS. As soon as practicable following the date hereof, Parent
and the Company will each use all reasonable efforts to obtain any material
consents, waivers and approvals under any of its or its Subsidiaries' respective
Contracts required to be obtained in connection with the consummation of the
transactions contemplated hereby.

     5.9  TERMINATION OF 401(K) PLANS. Effective no later than the day
immediately preceding the Closing Date, the Company and its Affiliates, as
applicable, shall each terminate any and all group severance, separation or
salary continuation plans, programs or arrangements and any and all plans
intended to include a Code Section 401(k) arrangement (unless Parent provides
written notice to the Company that such 401(k) plans shall not be terminated)
(collectively, "Company Plans"). Unless Parent provides such written notice to
the Company, no later than five business days prior to the Closing Date, the
Company shall provide Parent with evidence that such Company Plan(s) have been
terminated (effective as of the day immediately preceding the Closing Date)
pursuant to resolutions of the Company's Board of Directors. The form and
substance of such resolutions shall be subject to prior review and approval of
Parent. The Company also shall take such other actions in furtherance of
terminating such Company Plan(s) as Parent may reasonably require. In the event
that the distribution or rollover of assets from the trust of a Company Plan
that is terminated is reasonably anticipated to trigger liquidation charges,
surrender charges, or other fees to be imposed upon the account of any
participant or beneficiary of such terminated plan or upon the Company or plan
sponsor, then the Company shall take such all such actions as are necessary to
reasonably estimate the amount of such charges and/or fees and provide such
estimate in writing to Parent prior to the Closing Date.

                                      A-49


     5.10 INDEMNIFICATION.

          (a)  INDEMNITY. From and after the Effective Time, Parent will cause
the Surviving Corporation to, fulfill and honor in all respects the obligations
of the Company pursuant to any indemnification agreements between the Company
and its directors and officers immediately prior to the Effective Time and
identified on Schedule 5.10 (the "INDEMNIFIED PARTIES"), subject to applicable
law. The Certificate of Incorporation and Bylaws of the Surviving Corporation
will contain provisions with respect to exculpation, indemnification and
advancement of expenses that are at least as favorable to the Indemnified
Parties as those contained in the Certificate of Incorporation and Bylaws of the
Company as in effect on the date hereof, which provisions will not be amended,
repealed or otherwise modified for a period of six (6) years from the Effective
Time in any manner that would adversely affect the rights thereunder of
Indemnified Parties, unless such modification is required by law.

          (b)  INSURANCE. For a period of six (6) years after the Effective
Time, Parent will cause the Surviving Corporation to use all reasonable efforts
to cause to be maintained directors' and officers' liability insurance
maintained by the Company covering those persons who are covered by the
Company's directors' and officers' liability insurance policy as of the date
hereof for events occurring prior to the Effective Time on terms comparable to
those applicable to the current directors and officers of the Company; PROVIDED,
HOWEVER, that in no event will the Surviving Corporation be required to expend
in excess of 200% of the annual premium currently paid by the Company for such
coverage and which is set forth on Schedule 5.10 of the Company Disclosure
Letter (and to the extent annual premium would exceed 200% of the annual premium
currently paid by the Company for such coverage, the Surviving Corporation or
Parent shall use all reasonable efforts to cause to be maintained the maximum
amount of coverage as is available for such amount that is 200% of such annual
premium).

          (c)  THIRD-PARTY BENEFICIARIES. This Section 5.10 is intended to be
for the benefit of, and shall be enforceable by the Indemnified Parties and
their heirs and personal representatives and shall be binding on Parent and the
Surviving Corporation and its successors and assigns. In the event Parent or the
Surviving Corporation or its successor or assign (i) consolidates with or merges
into any other Person and shall not be the continuing or surviving corporation
or entity in such consolidation or merger or (ii) transfers all or substantially
all of its properties and assets to any Person, then, and in each case, proper
provision shall be made so that the successor and assign of Parent or the
Surviving Corporation, as the case may be, honor the obligations set forth with
respect to Parent or the Surviving Corporation, as the case may be, in this
Section 5.10.

     5.11 MERGER SUB COMPLIANCE. Parent shall cause Merger Sub to comply with
all of Merger Sub's obligations under or relating to this Agreement. Merger Sub
shall not engage in any business which is not in connection with the Merger with
and into the Company pursuant to this Agreement.

Revenue Service Center.

     5.14 SPREADSHEET. The Company shall prepare and deliver to Parent at or
prior to the Closing a spreadsheet in a form acceptable to Parent, which
spreadsheet shall be dated as of the Closing Date, and which spreadsheet (the

(a) the names and holders of all Company Options and Company Restricted Stock;
(b) the number of shares of Company Common Stock underlying such Company
Options, and the number of shares of Company Restricted Stock, held by such
Persons; (c) the exercise price per share in effect as of immediately prior to
the Effective Time for each such Company Option; (d) the vesting status and
schedule for such Company Options and Company Restricted Stock held by each
holder; and (e) the tax status of each Company Option held by such holder under
Section 422 of the Code. A draft of the Spreadsheet shall be provided to Parent
by the Company no later than two (2) business days prior to the Closing.

     5.15 TAKEOVER LAWS. The Company shall, upon the request of Parent, take all
reasonable steps to exclude the applicability of, or to assist in any challenge
by Parent or Merger Sub to the validity or applicability to the Merger or any
other transaction contemplated by this Agreement of, any "moratorium", "control
share acquisition", "business combination", "fair price" or other form of
anti-takeover Legal Requirements of any jurisdiction that may purport to be
applicable to this Agreement.

     5.16 COOPERATION WITH FINANCING. The Company acknowledges that to fund
partially or in whole the Merger Consideration, Parent intends to raise capital
pursuant to a bank borrowing under a secured or unsecured loan, the issuance of
debt, equity or hybrid securities in a private placement or public offering or
some combination thereof (any of the foregoing, a "FINANCING"). The Company
agrees to provide Parent with such cooperation as may be reasonably requested by
Parent in connection with the arrangement and obtaining of any Financing,
including (a) participation in meetings, drafting sessions, due diligence
sessions, management presentation sessions, "road shows" and sessions with
rating agencies, (b) preparation of business projections, financial statements
(including pro forma financial statements), offering memoranda, private
placement memoranda, prospectuses, marketing materials and similar documents,
(c) providing access to the Company's senior officers and representatives and
the books and records, contracts and properties of the Company and its
Subsidiaries, (d) the execution and delivery of any pledge and security
documents,

                                      A-51


other financing documents, including any indemnity agreements, and (e)
furnishing, or causing to be furnished, such other requested certificates or
documents, comfort letters (including "negative assurance" comfort) of
accountants, consents of accountants for use of their reports (which shall be
unqualified) in any materials relating to the financing to be used in connection
with the transactions contemplated by this Agreement, legal opinions, surveys
and title insurance. The Company will use all commercially reasonable efforts to
assist Parent with the full satisfaction, on a timely basis, of the terms,
conditions, representations and warranties set forth in any commitment letter,
credit agreement, purchase agreement, underwriting agreement, placement agent
agreement or other definitive agreement for any such Financing. Notwithstanding
anything herein to the contrary, neither the Company, any of its Subsidiaries
nor any of their respective officers or directors shall be required to file any
registration statement with the SEC or pay any commitment or other similar fee
or incur any other liability in connection with the Financings contemplated
hereby prior to the Effective Time, including, without limitation, any pledge or
security documents or other definitive Financing documents. The terms of this
Section 5.16 relate only to the Company's obligation to cooperate with Parent in
connection with the arrangement of the Financing, and shall not be deemed to
create any additional condition on the obligations of Parent and Merger Sub to
consummate and effect the Merger; provided, however, that any noncompliance or
breach of this Section 5.16 is subject to the provisions of Section 6.3.

     5.17 COMPANY OPTIONS. The Company agrees that immediately prior to and
contingent upon the effectiveness of the Merger, all Company Options with an
exercise price less than $30.00 per share shall be purchased by the Company for
a cash payment equal to the amount by which $30.00 per share exceeds the
exercise price per share for each share of Company Common Stock subject to such
Company Options, multiplied by the number of shares issuable upon exercise in
full of such Company Options, such that there shall be no outstanding Company
Options as of the effectiveness of the Merger. The Company shall make all
appropriate withholding as may be required in accordance with applicable laws
and regulations for such purchase.

     5.18 COMPANY FAIRNESS OPINION. As soon as practicable following the date
hereof, the Company shall deliver to Parent and its legal counsel a copy of the
Company Fairness Opinion.

     5.19 PAYMENTS. No later than two (2) Business Days following the Closing,

the payment terms set forth in the executed Payment Agreements. Company shall
use all commercially reasonable efforts to cause the individuals set forth on

executed Payment Agreement at the Closing.

to (i) be materially adverse to the business, assets (including intangible
assets), capitalization, condition (financial or otherwise) or results of
operations of such Person taken as a whole with its Subsidiaries or (ii)
materially impede the authority of such entity to consummate the transactions
contemplated by this Agreement in accordance with the terms hereof and
applicable Legal Requirements; PROVIDED, HOWEVER, that, for purposes of clause
(i) above, in no event shall any of the following, alone or in combination, be

Adverse Effect on any Person: (A) any Effect resulting from compliance with the
requirements of this Agreement or proximately from the public announcement of
the execution of this Agreement or the pendency of the Merger, (B) any Effect
resulting from the announcement or pendency of the Merger, (C) any change in

taken into account in determining whether there has been or

is reasonably likely to be a Material Adverse Effect on any Person), (E) any
Effect that results from changes affecting any of the industries in which such
Person operates generally or the United States economy generally (which changes

respect), or (F) any Effect that results from changes affecting general

company), firm or other enterprise, association, organization, entity or
Governmental Entity.

application thereof, becomes or is declared by a court of competent jurisdiction
to be illegal, void or unenforceable, the remainder of this Agreement will
continue in full force and effect and the application of such provision to other
Persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the greatest extent possible, the economic, business and
other purposes of such void or unenforceable provision.

     8.7  OTHER REMEDIES; SPECIFIC PERFORMANCE.

          (a)  OTHER REMEDIES. Except as otherwise provided herein, any and all

                                      A-63


other remedy conferred hereby, or by law or equity upon such party, and the
exercise by a party of any one remedy will not preclude the exercise of any
other remedy. 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.

          (b)  SPECIFIC PERFORMANCE. It is accordingly agreed that the parties
shall be entitled to seek 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 having jurisdiction, this being in
addition to any other remedy to which they are entitled at law or in equity, and
each party hereby waives any requirement to post a bond in connection with any
such proceeding.

accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of law thereof.

     8.9  RULES OF CONSTRUCTION. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

     8.10 ASSIGNMENT. No party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval
of the other parties. Any purported assignment in violation of this Section 8.10
shall be void. Subject to the preceding sentence, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

     8.11 WAIVER OF JURY TRIAL. EACH OF PARENT, MERGER SUB AND THE COMPANY
HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING
OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR

The Board of Directors
Excel Technology, Inc.
41 Research Way
E. Setauket Way, NY 11733

Dear Members of the Board:

         We understand that Excel Technology,  Inc., a Delaware corporation (the
"Company"),  is  considering a transaction  whereby  Coherent,  Inc., a Delaware
corporation ("Coherent"), will acquire the Company (the "Transaction"). Pursuant
to the terms of an Agreement and Plan of Merger,  draft dated  February 16, 2006
(the "Agreement"),  each issued and outstanding share of the common stock of the
Company,  par value of $0.001 per share (the "Company Common Stock") (other than
certain shares specified in the Agreement),  will be converted into the right to
receive  $30.00 in cash (the  "Consideration")  and the  Company  will  become a
wholly owned subsidiary of Coherent. The terms and conditions of the Transaction
are more fully set forth in the Agreement.

         You have  requested  our  opinion as to the  fairness  from a financial
point of view to holders of the Company Common Stock of the  Consideration to be
received by such holders in the Transaction.

         UBS Securities LLC ("UBS") has acted as financial  advisor to the Board
of Directors of the Company in connection  with the Transaction and will receive
a fee for its services,  a portion of which is payable in  connection  with this
opinion and a significant  portion of which is contingent  upon  consummation of
the  Transaction.  In the ordinary  course of business,  UBS, its successors and
affiliates  may hold or trade,  for their own accounts and the accounts of their
customers,  securities of the Company and Coherent and, accordingly,  may at any
time hold a long or short position in such securities.

         Our opinion does not address the relative  merits of the Transaction as
compared to other business  strategies or  transactions  that might be available
with respect to the Company or the  Company's  underlying  business  decision to
effect the Transaction or constitute a recommendation  to any shareholder of the
Company as to how such shareholder  should vote with respect to the Transaction.
At your direction, we have not been asked to, nor do we, offer any opinion as to
the material terms (other than the  Consideration)  of the Agreement or the form
of the  Transaction.  In rendering  this  opinion,  we have  assumed,  with your
consent,  that (i) the final  executed form of the Agreement  does not differ in
any material respect from the draft that we have examined, (ii) Coherent and the
Company will comply with all the material  terms of the  Agreement and (iii) the
Transaction  will be consummated  in accordance  with the terms of the Agreement
without  any adverse  waiver or  amendment  of any  material  term or  condition
thereof.  We have  also  assumed  that  all  governmental,  regulatory  or other
consents and approvals

                                      B-1


necessary for the  consummation of the Transaction  will be obtained without any
material adverse effect on the Company or the Transaction.

         In arriving at our opinion,  we have, among other things:  (i) reviewed
certain  publicly  available  business  and  historical  financial   information
relating to the Company and Coherent;  (ii) reviewed certain internal  financial
information  and other data relating to the business and financial  prospects of
the Company, including estimates and financial forecasts for calendar years 2006
and 2007 prepared by management of the Company,  that were provided to us by the
Company and not publicly  available,  as well as publicly  available Wall Street
research estimates for the Company;  (iii) conducted discussions with members of
the senior  management  of the Company  concerning  the business  and  financial
prospects of the Company;  (iv) reviewed publicly available  financial and stock
market data with respect to certain  other  companies we believe to be generally
relevant;  (v) compared the financial terms of the Transaction with the publicly
available  financial  terms of  certain  other  transactions  we  believe  to be
generally  relevant;  (vi) reviewed the current and historical  market prices of
the Company Common Stock;  (vii) reviewed the  Agreement;  and (viii)  conducted
such other financial studies,  analyses and investigations,  and considered such
other information,  as we deemed necessary or appropriate.  At your request,  we
have  contacted  third parties to solicit  indications of interest in a possible
Transaction  with the Company and held discussions with certain of these parties
prior to the date hereof.

         In connection with our review,  with your consent,  we have not assumed
any  responsibility  for  independent  verification  of any  of the  information
reviewed by us for the  purpose of this  opinion  and have,  with your  consent,
relied on such information being complete and accurate in all material respects.
In addition,  with your consent, we have not made any independent  evaluation or
appraisal of any of the assets or  liabilities  (contingent or otherwise) of the
Company or Coherent,  nor have we been  furnished  with any such  evaluation  or
appraisal.  With respect to the financial  forecasts  and estimates  referred to
above,  we have  assumed,  at your  direction,  that they  have been  reasonably
prepared  on a basis  reflecting  the best  currently  available  estimates  and
judgments of the  management of the Company as to the future  performance of the
Company.  Our opinion is  necessarily  based on economic,  monetary,  market and
other  conditions as in effect on, and the  information  made available to us as
of, the date hereof.

         Based upon and subject to the foregoing,  it is our opinion that, as of
the date hereof,  the Consideration to be received by the holders of the Company
Common Stock in the Transaction is fair, from a financial point of view, to such
holders.

         This  opinion is provided  for the benefit of the Board of Directors of
the Company in connection with, and for the purpose of, its consideration of the
Transaction.

                          Very truly yours,

                          UBS SECURITIES LLC

         (a)      Any stockholder of a corporation of this State who holds
shares of stock on the date of the making of a demand pursuant to subsection of
this section with respect to such shares, who continuously holds such shares
through the effective date of the merger or consolidation, who has otherwise
complied with subsection (d) of this section and who has neither voted in favor
of the merger or consolidation nor consented thereto in writing pursuant to
ss.228 of this title shall be entitled to an appraisal by the Court of Chancery
of the fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

         (b)      Appraisal rights shall be available for the shares of any
class or series of stock of a constituent corporation in a merger or
consolidation to be effected pursuant to ss. 251 (other than a merger effected
pursuant to ss.251(g) of this title), ss.252, ss.254, ss.257, ss.258, ss.263 or
ss.264 of this title:

                  (1)      Provided, however, that no appraisal rights under
this section shall be available for the shares of any class or series of stock,
which stock, or depository receipts in respect thereof, at the record date fixed
to determine the stockholders entitled to receive notice of and to vote at the
meeting of stockholders to act upon the agreement of merger or consolidation,
were either (i) listed on a national securities exchange or designated as a
national market system security on an interdealer quotation system by the
National Association of Securities Dealers. Inc. or (ii) held of record by more
than 2,000 holders; and further provided that no appraisal rights shall be
available for any shares of stock of the constituent corporation surviving a
merger if the merger did not require for its approval the vote of the
stockholders of the surviving corporation as provided in subsection (f) of
ss.251 of this title.

                  (2)      Notwithstanding paragraph (1) of this subsection,
appraisal rights under this section shall be available for the shares of any
class or series of stock of a constituent corporation if the holders thereof are
required by the terms of an agreement of merger or consolidation pursuant to
ss.ss. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such
stock anything except:

                           a.       Shares of stock of the corporation surviving
         or resulting from such merger or consolidation, or depository receipts
         in respect thereof;

                           b.       Shares of stock of any other corporation, or
         depository receipts in respect thereof, which shares of stock (or
         depository receipts in respect thereof) or depository receipts at the
         effective date of the merger or consolidation will be either listed on
         a national securities exchange or designated as a national market
         system security on an interdealer quotation system by the National
         Association of Securities Dealers, Inc. or held of record by more than
         2,000 holders;

                                      C-1


                           c        Cash in lieu of fractional shares or
         fractional depository receipts described in the foregoing subparagraphs
         a. and b. of this paragraph; or

                           d.       Any combination of the shares of stock,
         depository receipts and cash in lieu of fractional shares or fractional
         depository receipts described in the foregoing subparagraphs a., b. and
         c. of this paragraph.

                  (3)      In the event all of the stock of a subsidiary
Delaware corporation party to a merger effected under ss. 253 of this title is
not owned by the parent corporation immediately prior to the merger, appraisal
rights shall be available for the shares of the subsidiary Delaware corporation.

         (c)      Any corporation may provide in its certificate of
incorporation that appraisal rights under this section shall be available for
the shares of any class or series of its stock as a result of an amendment to
its certificate of incorporation, any merger or consolidation in which the
corporation is a constituent corporation or the sale of all or substantially all
of the assets of the corporation. If the certificate of incorporation contains
such a provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.

         (d)      Appraisal rights shall be perfected as follows:

                  (1)      If a proposed merger or consolidation for which
appraisal rights are provided under this section is to be submitted for approval
at a meeting of stockholders, the corporation, not less than 20 days prior to
the meeting, shall notify each of its stockholders who was such on the record
date for such meeting with respect to shares for which appraisal rights are
available pursuant to subsection (b) or (c) hereof that appraisal rights are
available for any or all of the shares of the constituent corporations, and
shall include in such notice a copy of this section. Each stockholder electing
to demand the appraisal of such stockholder's shares shall deliver to the
corporation, before the taking of the vote on the merger or consolidation, a
written demand for appraisal of such stockholder's shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
such stockholder's shares. A proxy or vote against the merger or consolidation
shall not constitute such a demand. A stockholder electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or

                  (2)      If the merger or consolidation was approved pursuant
to ss.228 or ss.253 of this title, then, either a constituent corporation before
the effective date of the merger or consolidation, or the surviving or resulting
corporation within ten days thereafter, shall notify each of the holders of any
class or series of stock of such constituent corporation who are entitled to
appraisal rights of the approval of the merger or consolidation and that
appraisal rights are available for any or all shares of such class or series of
stock of such constituent corporation, and shall include in such notice a copy
of this section. Such notice may, and, if given on or after the effective date
of the merger or consolidation, shall, also notify such stockholders of the
effective date of the merger or consolidation. Any stockholder entitled to
appraisal rights may, within 20 days after the date of mailing of such notice,
demand in writing from the surviving or resulting corporation the appraisal of
such holder's shares. Such demand will be sufficient if it reasonably informs
the corporation of the identity of the stockholder and that the stockholder
intends thereby to demand the appraisal of such holder's shares. If such notice
did not notify stockholders of the effective date of the merger or
consolidation, either (i) each such constituent corporation shall send a second
notice before the effective date of the merger or consolidation notifying each
of the holders of any class or series of stock of such constituent corporation
that are entitled to appraisal rights of the effective date of the merger or

                                      C-2


consolidation or (ii) the surviving or resulting corporation shall send such a
second notice to all such holders on or within 10 days after such effective
date; provided, however, that if such second notice is sent more than 20 days
following the sending of the first notice, such second notice need only be sent
to each stockholder who is entitled to appraisal rights and who has demanded
appraisal of such holder's shares in accordance with this subsection. An
affidavit of the secretary or assistant secretary or of the transfer agent of
the corporation that is required to give either notice that such notice has been
given shall, in the absence of fraud, be prima facie evidence of the facts
stated therein. For purposes of determining the stockholders entitled to receive
either notice, each constituent corporation may fix, in advance, a record date
that shall be not more than 10 days prior to the date the notice is given,
provided, that if the notice is given on or after the effective date of the
merger or consolidation, the record date shall be such effective date. If no
record date is fixed and the notice is given prior to the effective date, the
record date shall be the close of business on the day next preceding the day on
which the notice is given.

         (e)      Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

         (f)      Upon the filing of any such petition by a stockholder, service
of a copy thereof shall be made upon the surviving or resulting corporation,
which shall within 20 days after such service file in the office of the Register
in Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

         (g)      At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

                                      C-3


         (h)      After determining the stockholders entitled to an appraisal,
the Court shall appraise the shares, determining their fair value exclusive of
any element of value arising from the accomplishment or expectation of the
merger or consolidation, together with a fair rate of interest, if any, to be
paid upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any stockholder
entitled to participate in the appraisal proceeding, the Court may, in its
discretion, permit discovery or other pretrial proceedings and may proceed to
trial upon the appraisal prior to the final determination of the stockholder
entitled to an appraisal. Any stockholder whose name appears on the list filed
by the surviving or resulting corporation pursuant to subsection (f) of this
section and who has submitted such stockholder's certificates of stock to the
Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that such stockholder is not entitled
to appraisal rights under this section.

         (i)      The Court shall direct the payment of the fair value of the
shares, together with interest, if any, by the surviving or resulting
corporation to the stockholders entitled thereto. Interest may be simple or
compound, as the Court may direct. Payment shall be so made to each such
stockholder, in the case of holders of uncertificated stock forthwith, and the
case of holders of shares represented by certificates upon the surrender to the
corporation of the certificates representing such stock. The Court's decree may
be enforced as other decrees in the Court of Chancery may be enforced, whether
such surviving or resulting Corporation be a corporation of this State or of any
state.

         (j)      The costs of the proceeding maybe determined by the Court and
taxed upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

         (k)      From and after the effective date of the merger or
consolidation, no stockholder who has demanded appraisal rights as provided in
subsection (d) of this section shall be entitled to vote such stock for any
purpose or to receive payment of dividends or other distributions on the stock
(except dividends or other distributions payable to stockholders of record at a
date which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal of
such stockholder's demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding
in the Court of Chancery shall be dismissed as to any stockholder without the
approval of the Court, and such approval may be conditioned upon such terms as
the Court deems just.

         (l)      The shares of the surviving or resulting corporation to which
the shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
