all such lawful acts and things as are not directed or required by the Act, the
Certificate of Formation or this Agreement to be exercised or done by the
Members. Subject to the other provisions of this Agreement, it is intended that
the powers and authority of the Board of Managers shall be substantially the
same as the powers and authority of, and that the Board of Managers act in
substantially the same manner as, a board of directors of a for profit, stock
corporation formed under the laws of the State of Delaware to which the
provisions of Subchapter XIV of the Delaware General Corporation Law, 8 Del. Ch.
Sections 341 ff., are not applicable. Notwithstanding the above, the

recapitalization or merger.

         4.2 Number and Designation. Through June 30, 2006 the Board of Managers

him without Good Reason or by PerkinElmer for Cause, as such terms are defined
in the Employment Agreement dated as of July 1, 2002 between PerkinElmer and
Carl, at which time Carl shall also be deemed to have resigned as a Manager) and
three Managers designated by PerkinElmer. Managers shall hold office until their
successors are designated and qualified or until his, her or its earlier removal
or resignation in accordance with the provisions hereof. Managers may but need
not be Members. After June 30, 2006, or at such time prior thereto as Carl's

PerkinElmer for Cause, the Board of Managers shall consist solely of persons
designated by PerkinElmer.

         4.3 Meetings of Managers. The Board of Managers may hold meetings, both

by mail or 48 hours' notice to each Manager either personally or by facsimile
transmission. Managers may participate in a meeting of the Board of Managers by
means of conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other, and such
participation in a meeting shall constitute presence in person at the meeting.
At all meetings of the Board of Managers, a majority of the Managers shall
constitute a quorum for the transaction of business. If a quorum is not present
at any meeting of the Board of Managers, the Managers present thereat may
adjourn the meeting from time to time, without notice other than announcement at

         4.4 Action by Consent Without Meeting. On any matter that is to be
voted on by the Board of Managers, the Managers may take such action without a
meeting, without prior notice and without a vote if a consent or consents in
writing, setting forth the action so taken, shall be signed by such number of
Managers as would be entitled to take action at a duly constituted meeting of
the Board of Managers at which all Managers were present.

         4.5 Proxy. Managers may not vote at a meeting or execute a consent by
proxy.

         4.6 Removal; Vacancies; Resignation. Managers designated by PerkinElmer
may be removed and/or replaced at any time, with or without cause by
PerkinElmer. Any Manager may resign as a Manager at any time by giving written
notice to all of the other Managers and the sole Member. The resignation of any
Manager will take effect ten (10) days after the date of such notice or at such
later time as shall be specified in such notice.

                                 INDEMNIFICATION

         9.1 Indemnification.

            (a) To the fullest extent permitted by the Act and by law, the
Managers, Members and officers of the Company (herein referred to as
"Indemnitees") shall, in accordance with this Section 9.1, be indemnified and
held harmless by the Company from and against any and all loss, claims, damages,
liabilities joint and several, expenses (including reasonable legal expenses),
judgments, fines, settlements and other amounts (collectively, "Damages")
arising from any and all claims, demands, actions, suits or proceedings (civil,
criminal, administrative or investigative) (collectively, "Claims") in which
they may be involved, as a party or otherwise, by reason of their management of,
or involvement in, the affairs of the Company, or rendering of advice or
consultation with respect thereto, or which relate to the Company, its
properties, business or affairs, if such Indemnitee acted in good faith and in a
manner such Indemnitee reasonably believed to be in, or not opposed to, the best
interests of the Company and in accordance with the terms of this Agreement, and
with respect to any criminal proceeding, had no reasonable cause to believe the
conduct of such Indemnitee was unlawful. The termination of a proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere, or
its equivalent, shall not, of itself, create a presumption that the Indemnitee
did not act in good faith and in a manner which the Indemnitee reasonably
believed to be in, or not opposed to, the best interests of the Company or that
the Indemnitee had reasonable cause to believe that the Indemnitee's conduct was
unlawful (unless there has been a final adjudication in the proceeding that the
Indemnitee did not act in good faith and in a manner which the Indemnitee
reasonably believed to be in or not opposed to the best interests of the
Company; or that the Indemnitee did have reasonable cause to believe that the
Indemnitee's conduct was unlawful). Notwithstanding the foregoing, no Indemnitee
shall be entitled to indemnification hereunder for any liability arising from
the gross negligence or willful misconduct or reckless disregard in the
performance of such Indemnitee's duties under this Agreement. Further, no
Indemnitee shall be entitled to indemnification hereunder for Damages arising
from or related to Claims brought by the sole Member for such Indemnitee's
breach of any provision of this Agreement and/or any provision of the Purchase
and Sale Agreement or the Option Exercise Agreement.

            (b) The Company may also indemnify any Person who was or is a party
or is threatened to be made a party to any threatened, pending, or completed
action by or in the right of the Company to procure a judgment in its favor by
reason of the fact that such Person is or was an officer, employee or agent of
the Company, against expenses actually or reasonably incurred by such Person in
connection with the defense or settlement of such action, if such Person acted

in good faith and in a manner such Person reasonably believed to be in, or not
opposed to, the best interests of the Company, except that indemnification shall
be made in respect of any claim, issue or matter as to which such Person shall
have been adjudged to be liable for misconduct in the performance of the
Person's duty to the Company only to the extent that the court in which such
action or suit was brought, or another court of appropriate jurisdiction,
determines upon application that, despite the adjudication of liability, but in
view of all circumstances of the case, such Person is fairly and reasonably
entitled to indemnity for such expenses which such court shall deem proper. To
the extent that the Person has been successful on the merits or otherwise in
defense of any proceedings referred to herein, or in defense of any claim, issue
or matter therein, the Person shall be indemnified by the Company against
expenses actually and reasonably incurred by the Person in connection therewith.
Notwithstanding the foregoing, no Person shall be entitled to indemnification
hereunder for any liability arising from the gross negligence or willful
misconduct or reckless disregard in the performance of the Person's duties under
this Agreement.

            (c) The indemnification provided by this Section 9.1 shall not be
deemed to be exclusive of any other rights to which any Person may be entitled
under any agreement, or as a matter of law, or otherwise, both as to action in a
Person's official capacity and to action in another capacity.

         9.2 Advancement of Expenses. Expenses (including reasonable attorneys'
fees) incurred in defending any proceeding under Section 9.1 (a) or (b) shall be
paid by the Company in advance of the final disposition of such proceeding upon
receipt of an undertaking by or on behalf of the Indemnitee or Person to repay
such amount if it shall ultimately be determined that the Indemnitee or Person
is not entitled to be indemnified by the Company as authorized hereunder.

         9.3 Insurance. The Board of Managers shall have the power to purchase
and maintain insurance on behalf of the Company, the Managers, officers,
employees or agents of the Company and any other Indemnitees at the expense of
the Company, against any liability asserted against or incurred by them in any
such capacity whether or not the Company would have the power to indemnify such
Persons against such liability under the provisions of this Agreement.

Company have been distributed to the sole Member. Upon the completion of winding
up of the Company, a Certificate of Cancellation shall be filed with the
