                          AGREEMENT AND PLAN OF MERGER


         AGREEMENT AND PLAN OF MERGER (Cash Merger) (hereinafter called this
"Agreement"), dated as of December 16, 1996, among TYLAN GENERAL, INC., a
Delaware corporation (the "Company"), MILLIPORE CORPORATION, a Massachusetts
corporation ("Purchaser"), and MCTG ACQUISITION CORP., a Delaware corporation
and a wholly-owned subsidiary of Purchaser ("Purchaser Sub"), the Company and
Purchaser Sub sometimes being hereinafter collectively referred to as the
"Constituent Corporations."


                                    RECITALS

         WHEREAS, the Boards of Directors of Purchaser and the Company each have
determined that it is in the best interests of their respective stockholders for
Purchaser to acquire the Company upon the terms and subject to the conditions
set forth herein; and

         WHEREAS, the Company, Purchaser and Purchaser Sub desire to make
certain representations, warranties, covenants and agreements in connection with
this Agreement.

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


                                    ARTICLE I

                                THE TENDER OFFER

         1.1. Tender Offer.

                  (a) Provided that this Agreement shall not have been
terminated in accordance with Article IX hereof and none of the events set forth
in Annex A hereto shall have occurred or be existing, within five business days
after the public announcement of the execution of this Agreement, Purchaser Sub
will commence a tender offer (the "Offer") for all of the outstanding shares of
common stock, par value $0.001 per share (the "Shares"), of the Company at a
price of $16.00 per Share in cash, net to the seller, which Offer shall have an
initial expiration date not later than twenty (20) business days after the
commencement of the Offer. The obligation of Purchaser Sub to accept for payment
and pay for Shares tendered pursuant to the Offer shall be subject only to the
satisfaction or waiver of the conditions to the Offer set forth in Annex A
hereto. It is agreed that the Minimum Condition (as defined in Annex A) and the
other conditions set forth in Annex A hereto are for the sole benefit of
Purchaser Sub and may be asserted by Purchaser Sub regardless of the
circumstances giving rise to any such condition unless the Purchaser, Purchaser
Sub or their Affiliates shall have caused the circumstances giving
   2
rise to such condition. Purchaser Sub expressly reserves the right in its sole
discretion to waive, in whole or in part, at any time or from time to time, any
such condition (other than the Minimum Condition, which may not be waived
without the prior written consent of the Company), to increase the price per
Share payable in the Offer or to make any other changes in the terms and
conditions of the Offer, provided that, unless previously approved by the
Company in writing, no change may be made that decreases the price per Share
payable in the Offer, reduces the Minimum Condition, changes the form of
consideration payable in the Offer, reduces the maximum number of Shares to be
purchased in the Offer, imposes conditions to the Offer in addition to those set
forth in Annex A hereto or amends or modifies such conditions in any manner
adverse to the holders of Shares. Purchaser Sub covenants and agrees that,
subject to the conditions of the Offer set forth in Annex A hereto, Purchaser
Sub shall accept for payment and pay for Shares that have been validly tendered
and not withdrawn pursuant to the Offer as soon as it is permitted to do so
under applicable law; provided that, if the number of Shares that have been
validly tendered and not withdrawn represent less than 90% of the Shares
outstanding on a fully diluted basis, Purchaser Sub may extend the Offer up to
the fifth business day following the date on which all conditions to the Offer
shall first have been satisfied or waived.

                  (b) Purchaser agrees, as to the offer to purchase and related
letter of transmittal (which together constitute the "Offer Documents") and the
Company agrees, as to the Schedule 14D-9, that such documents shall, in all
material respects, comply with the requirements of the Securities Exchange Act
of 1934 (the "Exchange Act") and the rules and regulations thereunder and other
applicable laws. The Company and its counsel, as to the Offer Documents, and
Purchaser Sub and its counsel, as to the Schedule 14D-9, shall be given an
opportunity to review such documents prior to their being filed with the SEC.

                  (c) In connection with the Offer, the Company will cause its
transfer agent to furnish promptly to Purchaser Sub a list, as of a recent date,
of the record holders of Shares and their addresses, as well as mailing labels
containing the names and addresses of all record holders of Shares and lists of
security positions of Shares held in stock depositories. The Company will
furnish Purchaser Sub with such additional information (including, but not
limited to, updated lists of holders of Shares and their addresses, mailing
labels and lists of security positions) and such other assistance as Purchaser
or Purchaser Sub or their agents may reasonably request in communicating the
Offer to the record and beneficial holders of Shares. Subject to the
requirements of applicable law, and except for such steps as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate
the Merger, Purchaser Sub and its Affiliates and Associates shall hold in
confidence the information contained in any such labels, listings and files,
will use such information only in connection with the Offer and the Merger, and,
if this Agreement shall be terminated, will deliver to the Company all copies of
such information then in their possession.

         1.2. Company Action.

                  (a) The Company hereby approves of and consents to the Offer
and represents and warrants that its Board of Directors, at a meeting called and
held on December 16, 1996, by a 

                                        2
   3
unanimous vote of the directors present, (i) determined that this Agreement and
the transactions contemplated hereby, including the Offer and the Merger, are
fair to and in the best interests of the stockholders of the Company, (ii)
approved this Agreement and the transactions contemplated hereby, including the
Offer and the Merger, and (iii) resolved to recommend that the stockholders of
the Company accept the Offer, tender their Shares thereunder to Purchaser Sub
and, if required by applicable law, approve and adopt this Agreement and the
Merger. Subject to the fiduciary duties of the Board under applicable law (as
determined in good faith after consultation with independent counsel), the
Company hereby consents to the inclusion in the Offer Documents of the
recommendations of the Board described in this Section 1.2(a).

                  (b) As soon as practicable on or prior to the date of
commencement of the Offer, the Company shall file with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 (together with any
amendments or supplements thereto, the "Schedule 14D-9") and shall mail the
Schedule 14D-9 to the stockholders of the Company promptly after the
commencement of the Offer. The Schedule 14D-9 shall, subject to the fiduciary
duties of the Board under applicable law (as determined in good faith after
consultation with independent counsel), at all times contain the determinations,
approvals and recommendations described in Section 1.2(a). Purchaser, Purchaser
Sub and the Company each agrees promptly to correct any information provided by
it for use in the Schedule 14D-9 if and to the extent that any such information
shall have become false or misleading in any material respect and the Company
further agrees to take all steps necessary to cause the Schedule 14D-9 as so
corrected to be filed with the SEC and to be disseminated to holders of Shares,
in each case as and to the extent required by applicable federal securities
laws. Purchaser, Purchaser Sub and their counsel shall be given a reasonable
opportunity to review and comment on the Schedule 14D-9 prior to its filing with
the SEC and shall be provided with any comments the Company and its counsel may
receive from the SEC or its staff with respect to the Schedule 14D-9 promptly
after receipt of such comments.

         3.1. The Certificate of Incorporation. The Certificate of Incorporation
of the Purchaser Sub (the "Certificate") in effect at the Effective Time shall
be the Certificate of Incorporation of the Surviving Corporation, until duly
amended in accordance with the terms thereof, and the DGCL; provided, however,
that at the Effective Time the Certificate shall be amended to change the name
of the Surviving Corporation to Tylan General, Inc.

                                        4
   5
                                   ARTICLE IV

                             OFFICERS AND DIRECTORS
                          OF THE SURVIVING CORPORATION

         4.1. Officers and Directors. The directors of Purchaser Sub and the
officers of the Company, together with any additional individuals designated by
Purchaser, at the Effective Time shall, from and after the Effective Time, be
the directors and officers, respectively, of the Surviving Corporation until
their successors have been duly elected or appointed and qualified or until
their earlier death, resignation or removal in accordance with the Surviving
Corporation's Certificate of Incorporation and By-Laws.

         4.2. Actions by Directors. Following the election or appointment of
Purchaser's designees pursuant to Section 4.3 hereof, and prior to the Effective
Time, the approval of a majority of the Continuing Directors shall be required
to authorize (and such authorization shall constitute the authorization of the
Board of Directors of the Company and no other action on the part of the
Company, including any action by any other director of the Company, shall be
required to authorize) any termination of this Agreement by the Company, any
amendment of this Agreement requiring action by the Board of Directors of the
Company, any extension of time for the performance of any of the obligations or
other acts of Purchaser or Purchaser Sub, any waiver of compliance with any of
the agreements or conditions contained herein for the benefit of the Company or
any other rights of the Company hereunder, and any amendment or withdrawal by
the Board of Directors of its recommendation of the Merger pursuant to Section
7.3 hereof.

         4.3. Boards of Directors; Committees. If requested by Purchaser, the
Company will, subject to compliance with applicable law and immediately
following the purchase by Purchaser Sub of more than 50 percent of the
outstanding Shares pursuant to the Offer, take all actions necessary to cause
persons designated by Purchaser to become directors of the Company so that the
total number of such persons equals that number of directors, rounded up to the
next whole number, which represents the product of (x) the total number of
directors on the Board of Directors multiplied by (y) the percentage that the
number of Shares so purchased plus any Shares beneficially owned by Purchaser or
its Affiliates on the date hereof bears to the number of Shares outstanding at
the time of such purchase; provided, however, that in no event shall Purchaser
be entitled to designate a majority of the Board of Directors unless it is the
beneficial owner of Shares entitling it to exercise at least a majority of the
voting power of the Company's outstanding shares entitled to vote generally in
the election of directors. In furtherance thereof, the Company will use its
reasonable best efforts to secure the resignation of all but three directors, or
will increase the size of the Board, or both, as is necessary to permit
Purchaser's designees to be elected to the Company's Board of Directors;
provided, however, that prior to the Effective Time, the Company's Board of
Directors shall always have at least three Continuing Directors. Immediately
following the purchase by Purchaser Sub of more than 50% of the outstanding
Shares pursuant to the Offer, the Company, if so requested, will use its
reasonable 

                                       5
   6
efforts to cause persons designated by Purchaser to constitute the same
percentage of each committee of such board, each board of directors of each
subsidiary of the Company and each committee of each such board (in each case to
the extent of the Company's ability to elect such persons). The Company's
obligations to appoint designees to the Board of Directors shall be subject to
Section 14(f) of the Exchange Act and Rule 14f-1 thereunder. The Company shall
promptly take all actions required in order to fulfill its obligations under
this Section 4.3 and shall include in the Schedule 14D-9 such information as is
required under such Section 14(f), Rule 14(f)-1 and Schedule 14D-9. The
Purchaser will supply to the Company in writing and be solely responsible for
any information with respect to the Purchaser and its subsidiaries
(collectively, the "Purchaser Companies") and the nominees, directors and
Affiliates thereof required by Section 14(f) and Rule 14f-1 to be included in
the Schedule 14D-9.


                                    ARTICLE V

               CONVERSION OR CANCELLATION OF SHARES IN THE MERGER

         5.1. Conversion or Cancellation of Shares. The manner of converting or
canceling shares of the Company and Purchaser Sub in the Merger shall be as
follows:

                  (a) At the Effective Time, each Share issued and outstanding
immediately prior to the Effective Time (other than Shares owned by Purchaser,
Purchaser Sub or any other subsidiary of Purchaser) or Shares which are held by
stockholders ("Dissenting Stockholders") exercising appraisal rights pursuant to
Section 262 of the DGCL) shall, by virtue of the Merger and without any action
on the part of the holder thereof, be converted into the right to receive,
without interest, an amount in cash equal to $16.00 or such greater amount which
may be paid pursuant to the Offer (the "Merger Consideration"). All such Shares,
by virtue of the Merger and without any action on the part of the holders
thereof, shall no longer be outstanding and shall be canceled and retired and
shall cease to exist, and each holder of a certificate representing any such
Shares shall thereafter cease to have any rights with respect to such Shares,
except the right to receive the Merger Consideration for such Shares upon the
surrender of such certificate in accordance with Section 5.2 or the right, if
any, to receive payment from the Surviving Corporation of the "fair value" of
such Shares as determined in accordance with Section 262 of the DGCL.

                  (b) At the Effective Time, each Share issued and outstanding
at the Effective Time and owned by any of the Purchaser Companies, and each
Share issued and held in the Company's treasury at the Effective Time, shall, by
virtue of the Merger and without any action on the part of the holder thereof,
cease to be outstanding, shall be canceled and retired without payment of any
consideration therefor and shall cease to exist.

                  (c) At the Effective Time, each share of Common Stock, par
value $0.01 per share, of Purchaser Sub issued and outstanding immediately prior
to the Effective Time shall, by virtue of the Merger and without any action on
the part of Purchaser Sub or the holders of such shares, be converted into one
Share.

                                       6
   7
         5.2. Payment for Shares. Purchaser shall make available or cause to be
made available to the paying agent appointed by Purchaser with the Company's
prior approval (the "Paying Agent") amounts sufficient in the aggregate to
provide all funds necessary for the Paying Agent to make payments pursuant to
Section 5.1(a) hereof to holders of Shares issued and outstanding immediately
prior to the Effective Time. Promptly after the Effective Time, the Purchaser
shall instruct the Paying Agent to mail to each person who was, at the Effective
Time, a holder of record (other than any of the Purchaser Companies) of issued
and outstanding Shares a form (mutually agreed to by Purchaser and the Company)
of letter of transmittal and instructions for use in effecting the surrender of
the certificates which, immediately prior to the Effective Time, represented any
of such Shares in exchange for payment therefor. Upon surrender to the Paying
Agent of such certificates, together with such letter of transmittal, duly
executed and completed in accordance with the instructions thereto, the
Surviving Corporation shall promptly cause to be paid to the persons entitled
thereto a check in the amount to which such persons are entitled, after giving
effect to any required tax withholdings. No interest will be paid or will accrue
on the amount payable upon the surrender of any such certificate. If payment is
to be made to a person other than the registered holder of the certificate
surrendered, it shall be a condition of such payment that the certificate so
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of the certificate surrendered or establish to the satisfaction of the
Surviving Corporation or the Paying Agent that such tax has been paid or is not
applicable. One hundred eighty days following the Effective Time, the Surviving
Corporation shall be entitled to cause the Paying Agent to deliver to it any
funds (including any interest received with respect thereto) made available to
the Paying Agent which have not been disbursed to holders of certificates
formerly representing Shares outstanding on the Effective Time, and thereafter
such holders shall be entitled to look to the Surviving Corporation only as
general creditors thereof with respect to the cash payable upon due surrender of
their certificates. Notwithstanding the foregoing, neither the Paying Agent nor
any party hereto shall be liable to any holder of certificates formerly
representing Shares for any amount paid to a public official pursuant to any
applicable abandoned property, escheat or similar law. The Surviving Corporation
shall pay all charges and expenses, including those of the Paying Agent, in
connection with the exchange of cash for Shares and Purchaser shall reimburse
the Surviving Corporation for such charges and expenses.

         5.3. Dissenters' Rights. If any Dissenting Stockholder shall be
entitled to be paid the "fair value" of his or her Shares, as provided in
Section 262 of the DGCL, the Company shall give Purchaser notice thereof and
Purchaser shall have the right to participate, at its own expense, in all
negotiations and proceedings with respect to any such demands. Neither the
Company nor the Surviving Corporation shall, except with the prior written
consent of Purchaser, which consent shall not be unreasonably withheld,
voluntarily make any payment with respect to, or settle or offer to settle, any
such demand for payment. If any Dissenting Stockholder shall fail to perfect or
shall have effectively withdrawn or lost the right to dissent, the Shares held
by such Dissenting Stockholder shall thereupon be treated as though such Shares
had been converted into the Merger Consideration pursuant to Section 5.1.

                                        7
   8
         5.4. Transfer of Shares After the Effective Time. No transfers of
Shares shall be made on the stock transfer books of the Surviving Corporation at
or after the Effective Time.

         5.5. Stockholders' Meeting. If approval by the Company's stockholders
is required by applicable law to consummate the Merger, the Company, acting
through its Board of Directors, shall in accordance with applicable law, as soon
as practicable following the consummation of the Offer:

                  (i) duly call, give notice of, convene and hold a special
meeting of its stockholders (the "Stockholders' Meeting") for the purpose of
considering and taking action upon this Agreement and the Merger;

                  (ii) subject to the fiduciary duties of the Board under
applicable law (as determined in good faith after consultation with independent
counsel), include in the Proxy Statement the recommendation of its Board of
Directors that the stockholders of the Company vote in favor of the approval and
adoption of this Agreement and the transactions contemplated hereby (including
the Merger); and

                  (iii) use its reasonable best efforts (A) to obtain and
furnish the information required to be included by it in the Proxy Statement
and, after consultation with Purchaser, respond promptly to any comments made by
the SEC with respect to the Proxy Statement and any preliminary version thereof
and cause the Proxy Statement to be mailed to its stockholders at the earliest
practicable time following the consummation of the Offer and (B) subject to the
fiduciary duties of the Board under applicable law (as determined in good faith
after consultation with independent counsel), to obtain the necessary approvals
by its stockholders of this Agreement and the transactions contemplated hereby
(including the Merger).

         At such meeting, Purchaser and Purchaser Sub will vote all Shares owned
by them in favor of this Agreement and the transactions contemplated hereby
(including the Merger).

percentage of each subsidiary's outstanding capital stock or other equity

10,000,000 shares of preferred stock, par value $0.001 per share, of the Company
(the "Company Preferred Stock" and, together with the Company Common Stock and
the Company Stock Options, the "Company Securities") of which, as of the date
hereof, 100,000 shares of Series A Junior Participating Preferred Stock, $0.001

         (a) For purposes of this Section, the term "Company Benefit Plans"
shall mean all material pension, retirement, profit-sharing, deferred
compensation, stock option, employee stock ownership, severance pay, vacation,
bonus or other incentive plans, and all other employee programs, arrangements or
agreements, whether arrived at through collective bargaining or otherwise, all
medical, vision, dental and other health plans, all life insurance plans, and
all other employee benefit plans or fringe benefit plans, including, without
limitation, any "employee benefit plan," as that term is defined in Section 3(3)
of ERISA, currently adopted, maintained by, sponsored in whole or in part by, or
contributed to by the Company or its Affiliates for the benefit of employees,
retirees, dependents, spouses, directors, independent contractors or other
beneficiaries and under which employees, retirees, dependents, spouses,
directors, independent contractors, or other beneficiaries are eligible to

         (b) Except as set forth on Company Disclosure Schedule 6.1(i), no
Company Benefit Plan is or has been a multiemployer plan within the meaning of

Material Adverse Effect. No Company Benefit Plan provides for post-retirement
medical benefit obligations (without regard to COBRA obligations). Except as set
forth on Company Disclosure Schedule 6.1(i), no Company ERISA Plan which is a
defined benefit pension plan has any "unfunded current liability," as that term
is defined in Section 302(d)(8)(A) of ERISA, and the present fair market value
of the assets of any such plan exceeds the plan's "benefit liabilities," as that
term is defined in Section 4001(a)(16) of ERISA, when determined under actuarial
factors that would apply if the plan terminated in accordance with all
applicable legal requirements.

         (c) Company Disclosure Schedule 6.1(i) sets forth a true and correct
list of all Company Benefit Plans. The Company has provided Purchaser with
access to true and correct copies of each governing document for each Company
Benefit Plan, together with the most recent summary plan description and annual
report for each such plan and the actuarial report for any Company Benefit Plan

for any federal, state, local, foreign or other Taxes of any corporation or
entity other than the Company and its subsidiaries, including without limitation
any liability arising from the application of U.S. Treasury Regulations Section

Schedule 6.1(k), the Company has received no written notice that the use of any

                                    COVENANTS

person or entity; (v) make any acquisition of, or investment in, assets or
stock of any other person or entity involving an amount in excess of $100,000

not result in a material increase in benefits or compensation expense, adopt or
amend (except as may be required by law or as provided in this Agreement) any
bonus, profit sharing, compensation, severance, termination, 

                                       22

commitment or arrangement to do any of the foregoing.

                  (e) neither the Company nor any of its subsidiaries shall,
except in the ordinary and usual course of business, enter into any material
agreement or modify, amend or terminate any of its material agreements or waive,
release or assign any material rights or claims thereunder.

                  (f) neither the Company nor any of its subsidiaries will

         7.2. Acquisition Proposals. The Company agrees that neither the Company
nor any of its subsidiaries nor any of the respective officers and directors of
the Company or its subsidiaries shall, and the Company shall direct and use its
best efforts to cause its employees, agents and representatives (including,
without limitation, any investment banker, attorney or accountant retained by
the Company or any of its subsidiaries) not to, initiate, continue, solicit or
encourage, directly or indirectly, any inquiries or the making of any proposal
or offer (including, without limitation, any proposal or offer to stockholders
of the Company) or furnish any non-public information to any third party, with
respect to a merger, consolidation, business combination or similar transaction
involving, or any tender offer, exchange offer or other purchase of all or any
significant portion of the assets or any equity securities of, the Company or
any of its subsidiaries (any such proposal or offer being hereinafter referred
to as an "Acquisition Proposal") or, unless the Board of Directors of the
Company receives an unsolicited written offer with respect to a merger,
consolidation or sale of all or substantially all of the Company's assets or an
unsolicited tender or exchange offer for the Shares is commenced, which the
Board of Directors of the Company determines in good faith (after receiving
advice of independent legal counsel that such action is required for the
discharge of their fiduciary duties) is more favorable to the stockholders of
the Company than the Offer (an "Alternative Transaction"), engage in any
negotiations concerning, or provide any confidential information or data to, or
have any discussions with, any person relating to an Acquisition Proposal, or
otherwise facilitate any effort or attempt to make or implement an Acquisition
Proposal. The Company will immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any of the foregoing. The Company will as promptly as
reasonably practicable (and in any event within 24 hours) notify Purchaser (i)
if any such inquiries or proposals are received by, any such information is
requested from, or any such negotiations or discussions are sought to be
initiated with the Company, (ii) of its receipt of an acquisition proposal and
(iii) of the existence of an Alternative Transaction. Prior to furnishing
nonpublic information to, or entering into discussions or negotiations with, any
other persons or entities, the

                                       23
   24
Company shall obtain from such person or entity an executed confidentiality
agreement with terms no less favorable, taken as a whole, to the Company than
those contained in the Confidentiality Agreement, but which confidentiality
agreement shall not include any provision calling for an exclusive right to
negotiate with the Company, and the Company shall advise Purchaser of all such
nonpublic information delivered to such person concurrently with its delivery to
the requesting party.

         7.3. Meetings of the Company's Stockholders. Except as set forth in
this Section 7.3, the Board of Directors of the Company shall recommend approval
of the Agreement and the Merger and the Company shall take all lawful action to
solicit such approval. If the Board of Directors of the Company receives an
unsolicited written offer embodying an Alternative Transaction, the Board of
Directors may so amend or withdraw its recommendation and such withdrawal or
recommendation shall not constitute a breach of this Agreement. The Company's
proxy or information statement with respect to such meeting of stockholders (the
"Proxy Statement"), at the date thereof and at the date of such meeting, will
not include an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading;
provided, however, that the foregoing shall not apply to the extent that any
such untrue statement of a material fact or omission to state a material fact
was made by the Company in reliance upon and in conformity with written
information concerning the Purchaser Companies and nominees, directors and
Affiliates of such Purchaser Companies furnished to the Company by Purchaser
specifically for use in the Proxy Statement. The Proxy Statement shall not be
filed, and no amendment or supplement to the Proxy Statement will be made by the
Company, without consultation with Purchaser and its counsel. None of the
written information concerning the Purchaser Companies and the nominees,
directors and Affiliates thereof furnished to the Company by Purchaser
specifically for use in the Proxy Statement, at the date thereof and at the date
of the stockholders' meeting, will include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading.

         7.4. Filings; Other Action. Subject to the terms and conditions herein
provided, the Company and Purchaser shall: (a) promptly make their respective
filings and thereafter make any other required submissions under the HSR Act,
the Securities Act, the Exchange Act, Blue Sky Laws and the NASDAQ with respect
to the Offer and the Merger; and (b) use their
reasonable best efforts to promptly take, or cause to be taken, all other action
and do, or cause to be done, all other things necessary, proper or appropriate
under applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement.

         7.5. Access. Upon reasonable notice, the Company shall (and shall cause
each of its subsidiaries to) afford Purchaser's officers, employees, counsel,
accountants and other authorized representatives ("Representatives") access,
during normal business hours throughout the period prior to the Effective Time,
to its and its subsidiaries' properties, books, contracts and records and,
during such period, the Company shall (and shall cause each of its subsidiaries
to) furnish promptly to Purchaser all information concerning its business,
properties and personnel as

                                       24
   25
Purchaser or its Representatives may reasonably request, provided, that the
foregoing shall not require the Company to permit any inspection, or to disclose
any information, which in the reasonable judgment of the Company would result in
the disclosure of any trade secrets of third parties or violate any obligation
of the Company with respect to confidentiality All information obtained by
Purchaser and its Representatives pursuant to this Section 7.5 shall be treated
as "Evaluation Material" for all purposes of the Confidentiality Agreement.

         7.6. Notification of Certain Matters. Each party shall give prompt
notice to the other parties of (i) the occurrence or failure to occur of any
event, which occurrence or failure would be likely to cause any representation
or warranty or on its part contained in this Agreement to be untrue or
inaccurate at any time from the date hereof to the Effective Time, and (ii) any
material failure of the party, or any officer, director, employee or agent
thereof, to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder.

         7.7. Publicity. The initial press release shall be a joint press
release and thereafter, except as required by law, the Company and Purchaser
shall consult with each other prior to issuing any press releases or otherwise
making public statements with respect to the transactions contemplated hereby
and prior to making any filings with any Governmental Entity or with any
national securities exchange with respect thereto.

         7.8.     Benefits.

         (a) Stock Options; Stock Purchase Plan. Not later than the Effective
Time and continuing for a period of at least one hundred twenty (120) days after
the Effective Time, Purchaser shall offer in writing to each holder of a vested
Company Stock Option (whether or not such Company Stock Option terminated
effective as of the Effective Time by virtue of the Merger or would have
terminated thereafter) the opportunity to have such Company Stock Option
canceled and to receive an amount in cash equal to the excess of the Merger
Consideration over the exercise price per Share of such Company Stock Option
multiplied by the number of Shares previously subject to such Company Stock
Option, less all applicable withholding taxes. Whether or not vested, any
Company Stock Options not tendered for cancellation pursuant to such offer shall
continue to be governed by the terms of such Company Stock Option and the
applicable Company Option Plan. The Company shall have the right to amend the
terms of any Company Stock Option outstanding on the date hereof so that it
would become vested immediately prior to the Effective Time. The Company shall
have the right to cause all funds held in the Company's Employee Stock Purchase
Plan to be used to purchase Shares so that such Shares will be converted into
the right to receive cash in the Merger; provided that the Employee Stock
Purchase Plan is thereupon terminated.

                  (b) Employee Benefits. (i) Purchaser shall cause the Surviving
Corporation to provide to employees of the Company and its subsidiaries, who are
employed by the Surviving Corporation or its subsidiaries following the
Effective Time ("Company Employees"), employee benefits which in the aggregate
are substantially comparable to or greater than those currently provided by the
Company to such employees.

                                       25
   26
                           (ii) In the event that Company Employees are or
become eligible to participate in any plans maintained by the Purchaser or its
Subsidiaries ("Purchaser Benefit Plans"), Purchaser or its subsidiaries shall
grant such employees credit for purposes of eligibility, vesting and benefit
accrual, for all service credited for such purposes under comparable Company
Benefit Plans, provided, however, that, with respect to Purchaser's Retirement
Plan and such service with the Company shall be credited with respect to
eligibility and vesting only, but shall not be recognized for purposes of
determining the amount of retirement benefits, if any, under Purchaser's
Retirement Plan.

                           (iii) Any pre-existing condition exclusion under any
Purchaser Benefit Plan providing medical or dental benefits shall be no more
restrictive for any Company Employee who, immediately prior to commencing
participation in such Purchaser Benefit Plan, was participating in a Company
Benefit Plan providing medical or dental benefits and had satisfied any
pre-existing condition provision under such Company Benefit Plan. Any expenses
that were taken into account under a Company Benefit Plan providing medical or
dental benefits in which the Company Employee participated immediately prior to
commencing participation in a Purchaser Benefit Plan providing medical or dental
benefits shall be taken into account to the same extent under such Purchaser
Benefit Plan, in accordance with the terms of such Purchaser Benefit Plan, for
purposes of satisfying applicable deductible, coinsurance and maximum
out-of-pocket provisions and life-time benefit limits.

                  (c) Survivability. This Section 7.8 shall survive the
Effective Time, and is intended to be for the benefit of, and shall be
enforceable by, the Company Employees and the holders of Company Stock Options
and shall be binding on Purchaser and Purchaser Sub and the Surviving
Corporation and their respective successors and assigns.

         Section 7.9. Indemnification; Directors' and Officers' Insurance.

                  (a) The Certificate of Incorporation of the Surviving
Corporation shall contain the provisions with respect to indemnification not
less favorable to the directors and officers than those set forth in the
Certificate of Incorporation of the Company on the date of this Agreement, which
provisions shall not be amended, repealed or otherwise modified for a period of
six years after the Effective Time in any manner that would adversely affect the
rights thereunder of individuals who at the Effective Time were directors or
officers of the Company in respect of actions or omissions occurring at or prior
to the Effective Time (including, without limitation, the transactions
contemplated by this Agreement), unless such modification is required by Law.
Purchaser shall guarantee the obligations of the Surviving Corporation under
this Section 7.9(a).

                                       26
   27
                  (b) Purchaser shall cause the Surviving Corporation to use its
reasonable best efforts to maintain in effect for six years from the Effective
Time, if available, the coverage provided by the current directors' and
officers' liability insurance policies maintained by the Company (provided that
the Surviving Corporation may substitute therefor policies of at least the same
coverage containing terms and conditions which are not materially less
favorable) with respect to matters occurring prior to the Effective Time;
provided, however, that nothing contained herein shall require the Surviving
Corporation to incur any annual premium in excess of 200% of the last annual
aggregate premium paid prior to the date of this Agreement for all current
directors' and officers' liability insurance policies maintained by the Company
which the Company represents and warrants to be $150,000 (the "Current
Premium"). If such premiums for such insurance would at any time exceed 200% of
the Current Premium, then the Surviving Corporation shall cause to be maintained
policies of insurance which, in the Surviving Corporation's good faith
determination, provide the maximum coverage available at an annual premium equal
to 200% of the Current Premium.

                  (c) This Section 7.9 shall survive the Effective Time, and is
intended to be for the benefit of, and shall be enforceable by, the Indemnified
Parties and shall be binding on Purchaser and Purchaser Sub and the Surviving
Corporation and their respective successors and assigns.


         7.10. Takeover Statute. If any "fair price", "moratorium", "control
share acquisition" or other form of anti-takeover statute or regulation is or
shall become applicable to the transactions contemplated hereby, the Company and
the members of the Board of Directors of the Company shall grant such approvals
and take such actions as are necessary so that the transactions contemplated
hereby may be consummated as promptly as practicable on the terms contemplated
hereby and otherwise act to eliminate or minimize the effects of such statute or
regulation on the transactions contemplated hereby.

                                       27
   28
illegal; provided, however, that prior to either party invoking this provision,
such party shall have used its reasonable best efforts to have any such

Governmental Entity in connection with the execution and delivery of this
Agreement by the Company and the consummation of the transactions contemplated
hereby by the Company, Purchaser and Purchaser Sub shall have been made or
obtained (as the case may be) except where the failure to obtain the same would
not have a Company Material Adverse Effect.
