Item 2.       ACQUISITION OR DISPOSITION OF ASSETS.

              On November 23, 1999 SIPEX Corporation, (the "Registrant")
              acquired Calogic, a California corporation ("Calogic"), pursuant
              to an Agreement and Plan of Reorganization dated as of October 21,
              1999 (the "Merger Agreement") by and among the Registrant, CAT
              Acquisition Corporation I, a Delaware corporation and wholly owned
              subsidiary of the Registrant ("Merger Sub") and Calogic. Pursuant
              to the Merger Agreement, the Registrant acquired Calogic through
              the issuance of 3,300,000 shares of its common stock, $.01 par
              value (the "Purchase Price"), in exchange for all of the
              outstanding shares of capital stock of Calogic. The Purchase Price
              and the other terms of the transaction were determined in
              arms-length negotiations among the parties. A portion of the
              Purchase Price is being held in escrow to be released in
              accordance with the Merger Agreement and an Escrow Agreement, and
              the remainder of the Purchase Price was allocated among the
              stockholders of Calogic.

              The acquisition of Calogic is intended to qualify a tax-free
              reorganization under Section 368 of the Internal Revenue Code of
              1986, as amended. The Registrant will account for the transaction
              as a pooling-of-interests.

                      AGREEMENT AND PLAN OF REORGANIZATION


         AGREEMENT AND PLAN OF REORGANIZATION, dated as of October 21, 1999
(this "AGREEMENT"), by and among SIPEX Corporation, a Massachusetts corporation
("PARENT"); CAT Acquisition Corporation I, a Delaware corporation and a
wholly-owned subsidiary of Parent ("MERGER SUB"); Calogic, a California
corporation ("CALOGIC"); and the undersigned stockholders of Calogic (the
"STOCKHOLDERS")

         Intending to be legally bound, and in consideration of the mutual
representations, warranties, covenants and agreements contained herein, Parent,
Merger Sub, Calogic and the Stockholders agree as follows:


                                    ARTICLE I

                                   THE MERGER


          1.1 THE MERGER. Subject to the terms and conditions hereof, and in
accordance with the California General Corporation Law (the "CGCL") and the
Delaware General Corporation Law ("DGCL"), Merger Sub will be merged with and
into Calogic (the "MERGER"). A Certificate of Merger and any other required
documents (collectively, the "MERGER DOCUMENTS"), substantially in the form
attached as EXHIBIT 1.1, will be duly prepared, executed and acknowledged by
Calogic and Merger Sub and thereafter delivered to the Secretary of State of
California for filing in accordance with the CGCL and to the Secretary of State
of Delaware for filing in accordance with the DGCL for filing in accordance with
the DGCL contemporaneously with the Closing (as defined in Section 1.3). The
Merger will become effective at such time as the Merger Documents have been
filed with the Secretary of State of California and Delaware (whichever is
later) (the "EFFECTIVE TIME"). Following the Merger, Calogic will continue as
the surviving corporation of the Merger (the "SURVIVING CORPORATION") under the
laws of the State of California, and the separate corporate existence of Merger
Sub will cease.

         1.2 EFFECTS OF THE MERGER. At and after the Effective Time, (i) the
Merger will have all of the effects provided by the Articles of Merger and
applicable law, (ii) the Certificate of Incorporation of Calogic will be amended
in the form attached as APPENDIX A to EXHIBIT 1.1 until duly further amended,
(iii) the bylaws of Merger Sub will be the bylaws of the Surviving Corporation
until duly amended, (iv) the directors of Merger Sub will be the directors of
the Surviving Corporation, to hold office in accordance with the bylaws of the
Surviving Corporation, (v) the officers of Calogic will be the officers of the
Surviving Corporation, to hold office in accordance with the bylaws of the
Surviving Corporation and (vi) the issued and outstanding certificates for the
capital stock of Merger Sub will be the issued and outstanding certificates
initially representing all of the issued capital stock of the Surviving
Corporation. The Merger is intended to be a reorganization within the meaning of
Section 368(a)(2)(E) of the Internal Revenue Code of 1986, as amended (the
"CODE"), and this Agreement is intended to constitute a "plan of reorganization"
within the meaning of the regulations promulgated under Section 368 of the Code.


<PAGE>   8


         1.3 CLOSING. The closing of the transactions contemplated by this
Agreement (the "CLOSING") will take place as soon as practicable (but no more
than five (5) business days) after satisfaction or waiver of the last to be
fulfilled of the conditions set forth in Article IX that by their terms are not
to occur at the Closing (the "CLOSING DATE"), but in no event later than
November 30, 1999 at the offices of Testa, Hurwitz & Thibeault LLP in Boston,
Massachusetts, unless another date or place is agreed to in writing by Parent
and Calogic. If all of conditions set forth in Article IX hereof are determined
to be satisfied (or duly waived) at the Closing, concurrently with the Closing
the parties hereto will cause the Merger to be consummated by the filing of the
Merger Documents with the Secretary of State of California and Delaware. The
Closing will be deemed to have concluded at the Effective Time.

         1.4 APPROVAL BY THE STOCKHOLDERS OF CALOGIC. Calogic will take all
action necessary in accordance with applicable law, its Charter Documents (as
defined below) and any agreements to which it is a party to solicit the approval
of this Agreement, the Merger and all of the transactions contemplated hereby by
all stockholders of Calogic by means of a unanimous written consent of
stockholders in accordance with the CGCL, or if it is unable to obtain such
written consent, by a duly convened meeting of stockholders. Calogic will use
its reasonable best efforts to obtain such stockholder approval. Calogic
represents and warrants that its Board of Directors has duly (i) approved the
Merger in accordance with the CGCL and (ii) resolved to recommend to the
stockholders of Calogic that they approve this Agreement, the Merger and all of
the transactions contemplated hereby.

         1.5 APPROVAL BY MERGER SUB AND PARENT. Merger Sub represents and
warrants that its Board of Directors has duly (i) approved the Merger in
accordance with the DGCL and (ii) resolved to recommend to the stockholders of
Merger Sub that they approve this Agreement, the Merger and all of the
transactions contemplated hereby. Parent represents and warrants that (i) its
Board of Directors has duly approved the Merger in accordance with the
Massachusetts General Corporation Law (the "MGCL") and (ii) it is not necessary
under the MGCL that the shareholders of Parent approve this Agreement, the

              CONVERSION AND EXCHANGE OF SHARES; DISSENTING SHARES


         2.1 CONVERSION OF SHARES OF CALOGIC COMMON STOCK.

                  (a) Subject, without limitation, to the provisions of Section
2.3 hereof, at the Effective Time, all of the shares of common stock, no par
value, of Calogic ("CALOGIC COMMON STOCK") issued and outstanding immediately
prior to the Effective Time (excluding any Calogic Common Stock held by Parent
or Merger Sub or any other subsidiary of Parent, or by Calogic or any subsidiary
of Calogic, which shares ("EXCLUDED SHARES") will be automatically canceled in
the Merger without payment of any consideration therefor, and excluding
Dissenting Shares (as defined in Section 2.3 hereof)), will automatically, by
virtue of the Merger and without any action on the part of the holder thereof,
be converted into shares of common stock, $.01 par value per share, of Parent
("PARENT COMMON STOCK") in accordance with Section 2.1(c), and cash (rounded
down to the nearest whole cent) in lieu of fractional shares, if any, pursuant
to Section 2.6 below. Shares of Calogic Common Stock that are

                                      -2-

<PAGE>   9


actually issued and outstanding immediately prior to the Effective Time,
excluding the Excluded Shares, are sometimes referred to herein as the
"OUTSTANDING CALOGIC SHARES." All rights, warrants or options to acquire Calogic
Common Stock and securities convertible into Calogic Common Stock that
areoutstanding immediately prior to the Effective Time and do not expire
pursuant to their terms on or before the Closing (each of which is specifically
identified in Section 3.2 of the Calogic Disclosure Schedule (as defined below))
are sometimes referred to herein as the "OUTSTANDING CALOGIC OPTIONS."

                  (b) The maximum number of shares of Parent Common Stock to be
issued in exchange for the acquisition of all Outstanding Calogic Shares and the
assumption of all Outstanding Calogic Options will be 3,400,000, provided such
maximum number shall be adjusted, as appropriate, for any stock split, stock
dividend, reclassification, recapitalization or similar event. Such shares are
herein referred to as the "PARENT MERGER SHARES".

                  (c) The ratio at which one Outstanding Calogic Share will be
converted into shares of Parent Common Stock at the Effective Time is herein
called the "CONVERSION RATIO" and will be calculated as set forth in this
Section 2.1(c). Subject to Section 2.3, at the Effective Time, each Outstanding
Calogic Share will be converted into the right to receive that number (which may
be a fraction) of shares of Parent Common Stock that equals the quotient
obtained by DIVIDING the number of Parent Merger Shares by the sum of the number
of Outstanding Calogic Shares PLUS the number of shares of Calogic Common Stock
issuable upon the exercise or conversion of all Outstanding Calogic Options.
Each holder of Outstanding Calogic Shares will be entitled to receive that
aggregate number of shares of Parent Common Stock equal to the Conversion Ratio
multiplied by the number of Outstanding Calogic Shares held by such holder
immediately prior to the Effective Time, subject to Section 2.3 herein.

                  (d) At the Effective Time, each share of common stock, $.01
par value, of Merger Sub issued and outstanding immediately prior to the
Effective Time will, by virtue of the Merger and without any action on the part
of the holder hereof, be converted into one share of common stock, no par value,
of the Surviving Corporation.

         2.2 ESCROW SHARES. Ten percent of the Parent Merger Shares (the "ESCROW
SHARES") will be deposited and held in escrow in accordance with an escrow
agreement substantially in the form attached as EXHIBIT 2.2 (the "ESCROW
AGREEMENT") as the first source, but not the sole source, of indemnification
payments that may become due to Parent pursuant to Article X. The Escrow Shares
will be withheld on a pro rata basis among the holders of the Outstanding
Calogic Shares. The exact number of Escrow Shares held for the account of each
Calogic stockholder will be determined at the Closing by the agreement in
writing of Parent and Calogic. The delivery of the Escrow Shares will be made on
behalf of the holders of the Outstanding Calogic Shares in accordance with the
provisions hereof, with the same force and effect as if such shares had been
delivered by Parent directly to such holders and subsequently delivered by such
holders to the Escrow Agent. The adoption of this Agreement by stockholders of
Calogic will also constitute their approval of the terms and provisions of the
Escrow Agreement, which is an integral term of the Merger.

         2.3 DISSENTING SHARES. Any holder of shares of Calogic Common Stock
that are outstanding on the record date for the determination of which holders
will be entitled to vote for or against the Merger who did not vote such shares
in favor of the Merger or sign and deliver a written consent thereto with
respect to such shares (the shares of Calogic Common Stock then outstanding that
are not

                                      -3-

<PAGE>   10


thus voted or as to which such consents are not signed and delivered are
referred to as "DISSENTING SHARES") will be entitled to exercise dissenters'
rights pursuant to Chapter 13 of the CGCL with respect to such Dissenting Shares
provided that such holder meets all of the requirements of the CGCL with respect
to such Dissenting Shares, and will not be entitled to receive Parent Merger
Shares, unless otherwise provided by the CGCL or agreed in writing by Parent.
Calogic will, after consultation with Parent, give such notices with respect to
dissenters' rights as may be required by the CGCL as soon as practicable.

         2.4 DELIVERY OF EVIDENCE OF OWNERSHIP. At the Closing, each holder of a
certificate or other documentation representing Outstanding Calogic Shares,
other than Dissenting Shares, will surrender such certificates or other
documentation to Parent, and, if not previously delivered, duly executed
counterparts of this Agreement, the Escrow Agreement, the Investment Agreement
(as defined below) and the Registration Rights Agreement (as defined below) and
such other duly executed documentation as may be reasonably required by Parent
to effect a transfer of such shares, and upon such surrender and at the
Effective Time each such holder will be entitled to receive promptly after the
Effective Time from Parent or its transfer agent certificates registered in the
name of such holder representing the applicable number of Parent Merger Shares,
and the cash (calculated pursuant to Section 2.6, which will be paid by check),
to which such holder is entitled pursuant to the provisions of this Agreement,
with a portion of such shares to be deposited in escrow pursuant to the Escrow
Agreement, as provided in Section 2.2.

         2.5 NO FURTHER OWNERSHIP RIGHTS IN CALOGIC COMMON STOCK. The Merger and
its approval by the stockholders of Calogic and the execution of this Agreement
will be deemed, at the Effective Time, to constitute full satisfaction and
termination of all rights and agreements pertaining to Calogic Common Stock
pursuant to the CGCL, by contract or otherwise. After the Effective Time, there
will be no transfers on the stock transfer books of Calogic of Calogic Common
Stock. Until surrendered to Parent, each certificate for Calogic Common Stock
will, after the Effective Time, represent only the right to receive shares of
Parent Common Stock and the right to receive cash into which the shares of
Calogic Common Stock formerly represented thereby will have been converted
pursuant to this Agreement. Any dividends or other distribution declared after
the Effective Time with respect to Parent Common Stock will be paid to the
holder of any certificate for shares of Calogic Common Stock when the holder
thereof is entitled to receive a certificate for such holder's Parent Merger
Shares in accordance with this Agreement.

         2.6 NO FRACTIONAL SHARES. No certificates or scrip for fractional
shares of Parent Common Stock will be issued, no Parent stock split or dividend
will be paid in respect of any fractional share interest, and no such fractional
share interest will entitle the owner thereof to vote or to any rights of or as
a stockholder of Parent. In lieu of such fractional shares, any holder of
Outstanding Calogic Shares who would otherwise be entitled to a fraction of a
share of Parent Common Stock (after aggregating all fractional shares of Parent
Common Stock to be received by such holder) will be paid the cash value of such
fraction, which will be equal to such fraction MULTIPLIED BY the Parent Average
Closing Price. For purposes of this Agreement "PARENT AVERAGE CLOSING PRICE"
will be the average closing price of the Parent Common Stock as publicly
reported by the Nasdaq National Market over the ten Trading Days ending two
Trading Days prior to the Closing Date. "TRADING DAY" will mean days on which
closing prices for purchases and sales of Parent Common Stock are reported by
the Nasdaq National Market.

         2.7 ASSUMPTION OF STOCK OPTIONS. At the Effective Time, Parent shall
assume each outstanding Calogic Option (an "Outstanding Calogic Option") and
each holder thereof (each an "OPTION HOLDER") shall thereby be entitled to
acquire, by virtue of the Merger and without any action on the part of the
Option Holder, on substantially the same terms (including the dates and extent
of exercisability) and subject to the same conditions, including vesting, as
such Outstanding Calogic Option, the number of shares of Parent Common Stock
determined by MULTIPLYING the number of shares of Calogic Common Stock for which
such Outstanding Calogic Option is then exercisable in accordance with its terms
immediately prior to the Effective Time by the Conversion Ratio (rounded down to
the nearest whole share), at an exercise or conversion price per share of Parent
Common Stock (rounded up to the nearest whole cent) determined by dividing the
exercise price per share of Calogic Common Stock of such Outstanding Calogic
Option immediately prior to the Effective Time by the Conversion Ratio.


                                   ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF CALOGIC
                              AND THE STOCKHOLDERS


         Except as set forth in the disclosure schedule of Calogic dated as of
the date hereof and delivered herewith to Parent (the "CALOGIC DISCLOSURE
SCHEDULE") which identifies the section and subsection to which each disclosure
therein relates, and whether or not the Calogic Disclosure Schedule is referred

jointly and severally represent and warrant to Parent and Merger Sub as follows:

         3.1 ORGANIZATION, STANDING AND POWER; SUBSIDIARIES.

                   (a) Calogic is a corporation duly organized, validly existing
and in good standing under the laws of the State of California, has all
requisite corporate power and authority to own, lease and operate its properties
and to carry on its businesses as now being conducted, and is duly qualified and
in good standing to do business in each jurisdiction in which a failure to so
qualify would have a material adverse effect on the Business Condition (as

to any Person (as defined below) means the business, financial condition,
results of operations or assets (without giving effect to the consequences of
the transactions contemplated by this Agreement, and other than changes in

"SUBSIDIARY" of any Person means a corporation, partnership, limited liability
company, joint venture or other entity of which such Person directly or
indirectly owns or controls a majority of the equity interests or voting
securities or other interests that are sufficient to elect a majority of the

                  All Subsidiaries of Calogic and their jurisdiction of
incorporation are completely and correctly listed in Section 3.1 of the Calogic

                  (b) Section 3.1 of the Calogic Disclosure Schedule contains a
complete and correct list of the Subsidiaries of Calogic and correctly sets

of capital stock of each Subsidiary of Calogic are owned beneficially and of

restrictions, claims, encumbrances or assessments of any nature whatsoever
("LIENS"); and there are no outstanding subscriptions, warrants, options,
convertible securities, or other rights (contingent or other) pursuant to which
any of the Subsidiaries is or may become obligated to issue any shares of its
capital stock to any Person other than Calogic or one of the other Subsidiaries.

         3.2 CAPITAL STRUCTURE.

                  (a) The authorized capital stock of Calogic consists of
2,500,000 shares of Calogic Common Stock, of which 345,000 shares are issued and
outstanding as of the date of this Agreement and no shares are issued and held
as treasury shares by Calogic. The Calogic Disclosure Schedule sets forth all
holders of Calogic Common Stock and the number of shares owned. The Calogic
Disclosure Schedule also sets forth any options, warrants, calls, conversion
rights, commitments, agreements, contracts, understandings, restrictions,
arrangements or rights of any character (each, an "CALOGIC OPTION") to which
Calogic is a party or by which Calogic may be bound obligating Calogic to issue,
deliver or sell, or cause to be issued, delivered or sold, additional shares of
the capital stock of Calogic, or obligating Calogic to grant, extend, or enter
into any such option, warrant, call, conversion right, conversion payment,
commitment, agreement, contract, understanding, restriction, arrangement or
right.

                  (b) All outstanding shares of Calogic Common Stock are, and
any shares of Calogic Common Stock issued upon exercise of any Outstanding
Calogic Options will be, validly issued, fully paid, nonassessable and not
subject to any preemptive rights (other than those which have been duly waived),
or to any agreement to which Calogic is a party or by which Calogic may be
bound. Calogic does not have outstanding any bonds, debentures, notes or other
indebtedness the holders of which (i) have the right to vote (or convertible or
exercisable into securities having the right to vote) with holders of shares of
Calogic Common Stock on any matter ("CALOGIC VOTING DEBT") or (ii) are or will
become entitled to receive any payment as a result of the execution of this
Agreement or the completion of the transactions contemplated hereby.

authorizations from all Governmental Entities (as defined below) necessary for
the lawful conduct of its business pursuant to all applicable statutes, laws,

Business Condition. There are no material violations or claimed violations known
by Calogic of any such license, permit or authorization or any such statute,
law, ordinance, rule or regulation. Assuming the receipt of all Consents (as

or local court or administrative order or process, statute, law, ordinance, rule
or regulation, or any contract, agreement or commitment to which Calogic is a
party, or under which Calogic is obligated, or by which Calogic or any of the
rights, properties or assets of Calogic are subject or bound; result in the
creation of any Lien upon, or otherwise adversely affect, any of the rights,
properties or assets of Calogic; terminate, amend or modify, or give any party
the right to terminate, amend, modify, abandon or refuse to perform or comply
with, any contract, agreement or commitment to which Calogic is a party, or

properties or assets of Calogic are subject or bound; or accelerate, postpone or
modify, or give any party the right to accelerate, postpone or modify, the time

a party, or under which Calogic may be obligated, or by which Calogic or any of
the rights, properties or assets of Calogic are subject or bound. Section 3.4 of
the Calogic Disclosure Schedule sets forth each agreement, contract or other
instrument binding upon Calogic requiring a notice or consent (by its terms or
as a result of any conflict or other contravention required to be disclosed in
the Calogic Disclosure Schedule pursuant to the preceding provisions of this
Section 3.4) as a result of the execution, delivery or performance of this
Agreement and all other agreements contemplated hereby by Calogic and the
Stockholders or the consummation of the Merger or any other transaction
described herein (each such notice or consent, a "CONSENT"). Assuming the
accuracy of the representations and warranties of Parent and Merger Sub
contained in this Agreement and the other agreements contemplated hereby, no
consent, approval, order, or authorization of or registration, declaration, or
filing with or exemption (also a "CONSENT") by, any court, administrative agency
or commission or other governmental authority or instrumentality, whether
domestic or foreign (each a "GOVERNMENTAL ENTITY") is required to be made or
obtained by Calogic or any of its Subsidiaries

Returns), including, without limitation, all Taxes which Calogic is obligated to
withhold for amounts owing to employees, creditors and third parties. All Tax
Returns filed by Calogic were complete and correct in all material respects, and
such Tax Returns correctly reflected the facts regarding the income, business,
assets, operations, activities, status and other matters of Calogic and any
other information required to be shown thereon. None of the Tax Returns filed by
Calogic or Taxes payable by Calogic have been the subject of an audit, action,
suit, proceeding, claim, examination, deficiency or assessment by any
Governmental Entity, and no such audit, action, suit, proceeding, claim,
examination, deficiency or assessment is currently pending or, to the knowledge
of Calogic, threatened. Calogic is not currently the beneficiary of any
extension of time within which to file any Tax Return, and Calogic has not
waived any statute of limitation with respect to any Tax or agreed to any
extension of time with respect to a Tax assessment or deficiency. All material
elections with respect to Taxes affecting Calogic, as of the date hereof, are
set forth in the Financial Statements or in Section 3.7 of the Calogic
Disclosure Schedule. None of the Tax Returns filed by Calogic contain a
disclosure statement under former Section 6661 of the Code or Section 6662 of
the Code (or any similar provision of state, local or foreign Tax law). Calogic
is not a party to any Tax sharing agreement or similar arrangement. Calogic has
never been a member of a group filing a consolidated federal income Tax Return
(other than a group the common parent of which was Calogic), and Calogic does
not have any liability for the Taxes of any Person (other than Calogic) under
Treasury Regulation Section 1.1502-6 (or any corresponding provision of state,
local or foreign Tax law), as a transferee or successor, by contract, or
otherwise.

                  (c) Calogic is not a party to any agreement, contract,
arrangement or plan that has resulted or would result, separately or in the
aggregate, in the payment of (i) any "excess parachute payments" within the
meaning of Section 280G of the Code (without regard to the exceptions set forth
in Sections 280G(b)(4) and 280G(b)(5) of the Code) or (ii) any amount for which
a deduction would be disallowed or deferred under Section 162 or Section 404 of
the Code. Calogic has not agreed to make any adjustment under Section 481(a) of
the Code (or any corresponding provision of state, local or foreign law) by
reason of a change in accounting method or otherwise, and Calogic will not be
required to make any such adjustment as a result of the transactions set forth
in this Agreement. Calogic does not have and has not had a permanent
establishment in any foreign country, as defined in any applicable Tax treaty or
convention between the United States and such foreign country. No portion of

the Parent Merger Shares is subject to the Tax withholding provisions of
Section 3406 of the Code, or of Subchapter A of Chapter 3 of the Code or of any
other provision of law. None of the assets of Calogic is property which is
required to be treated as being owned by any other Person pursuant to the
so-called "safe harbor lease" provisions of former Section 168(f)(8) of the
Code. None of the assets of Calogic directly or indirectly secures any debt, the
interest on which is tax exempt under Section 103(a) of the Code. None of the
assets of Calogic is "tax-exempt use property" within the meaning of Section
168(h) of the Code. No claim has ever been made by any Governmental Entity in a
jurisdiction where Calogic does not file Tax Returns that it is or may be
subject to Tax in that jurisdiction. Calogic has not participated in an
international boycott as defined in Section 999 of the Code. None of the shares
of outstanding capital stock of Calogic are subject to a "substantial risk of
forfeiture" within the meaning of Section 83 of the Code.

                  (d) There are no liens for Taxes (other than for ad valorem
Taxes not yet due and payable) upon the assets of Calogic. The unpaid Taxes of
Calogic did not, as of the Unaudited Balance Sheet Date, exceed the reserve for
actual Taxes (as opposed to any reserve for deferred Taxes established to
reflect timing differences between book and Tax income) as shown on the
Unaudited Balance Sheet, and will not exceed such reserve as adjusted for the
passage of time through the Closing Date in accordance with the past custom and
practice of Calogic in filing its Tax Returns (taking into account any Taxes
incurred as a result of the transactions contemplated by this Agreement).
Section 3.7 of the Calogic Disclosure Schedule sets forth Calogic's Tax basis in
each of its assets. Calogic is not a party to any joint venture, partnership,
limited liability company or other arrangement or contract which could be
treated as a partnership for federal income tax purposes.

period specified in Section 897(c)(1)(A)(ii) of the Code. Calogic has never
filed a consent pursuant to Section 341(f) of the Code, relating to collapsible
corporations. To the knowledge of Calogic, neither Calogic nor any of its
shareholders has taken or agreed to take any action that would reasonably be
expected to cause the Merger to fail to qualify as a reorganization within the
meaning of Section 368(a) of the Code.

been determined by the Internal Revenue Service to be so qualified and, to the
knowledge of Calogic, no event has occurred and no condition exists with respect
to the form or operation of such Plans that would cause the loss of such

claims for benefits incurred in the ordinary course of Plan activities) has been
brought against or with respect to any Plan. All contributions, reserves, or

written interpretation of, or announcement (whether or not written) by Calogic
relating to, or change in employee participation or coverage under, any Plan.
Neither Calogic nor any of its ERISA affiliates have any current or projected
liability in respect of post-employment or post-retirement welfare benefits for
retired or former employees of Calogic other than health care continuation
benefits required to be provided under applicable law. No tax under Section
4980B or 4980D of the Code has been incurred in respect of any Plan that is a
group health plan, as defined in Section 5000(b)(1) of the Code. Neither Calogic
nor any Plan has received a distribution of stock from any converted mutual
insurance company.

         3.19 CERTAIN AGREEMENTS. Except as contemplated by this Agreement,
neither the execution and delivery of this Agreement and all other agreements
contemplated hereby, nor the consummation of the transactions contemplated
hereby will: (i) result in any payment by Calogic (including, without
limitation, severance, unemployment compensation, parachute payment, bonus or
otherwise) becoming due to any director, employee, or independent contractor of
Calogic under any Plan, agreement, or

         3.23 ENVIRONMENTAL MATTERS. Except as set forth in the Environmental
Assessment Report (as defined in section 8.10) (i) to the knowledge of Calogic,
Calogic has complied in all material respects with all federal, state and local
laws (including, without limitation, case law, rules, regulations, orders,

intended to protect the environment and/or human health or safety (collectively,

         3.24 ENFORCEABILITY OF CONTRACTS, ETC.
                  (a) To the knowledge of Calogic, based upon the fact that
Calogic has not received written notice to the contrary, no Person that is a
party to any contract, agreement, commitment or plan to which Calogic is a party
has a valid defense, on account of non-performance or malfeasance by Calogic,
which would make any such contracts, agreement, commitment or plan not valid and
binding upon or enforceable against such parties in accordance with their terms,
except to the extent such

                                      -19-

<PAGE>   26


enforceability may be subject to or limited by bankruptcy, insolvency,
reorganization, arrangement or similar laws affecting the rights of creditors
generally and usual equity principles.

                  (b) To the knowledge of Calogic, based upon the fact that
Calogic has not received written notice to the contrary, neither Calogic nor any
other Person, is in material breach or violation of, or default under, any
material contract, agreement, arrangement, commitment or plan to which Calogic
is a party, and no event or action has occurred, is pending, or, to the
knowledge of Calogic, is threatened, which, after the giving of notice, or the
lapse of time, or otherwise, would constitute a material breach or a default by
Calogic or, to the knowledge of Calogic, any other Person, under any material
contract, agreement, arrangement, commitment or plan to which Calogic is a
party.

         3.25 ACCOUNTING MATTERS. To the knowledge of Calogic, neither Calogic
nor any of its affiliates has taken or agreed to, or plans to, take any action
that would prevent Parent from accounting for the Merger as a "pooling of
interests" in accordance with generally accepted accounting principles.
Accounting Principles Board Opinion No. 16 and all published rules, regulations
and policies of the Commission.

         3.26 YEAR 2000. To the knowledge of Calogic, any reprogramming required
to permit the proper functioning, in and following the year 2000, of Calogic's
computer systems and equipment containing embedded microchips used in Calogic's
business, and the testing of all such systems and equipment, as so reprogrammed,
will be completed by December 31, 1999. To the knowledge of Calogic, the cost to
the Company of such reprogramming and testing and the reasonably foreseeable
consequences of year 2000 to the Company (including, without limitation,
reprogramming errors, products or services provided by Calogic and the failure
of others' systems or equipment) will not have a material adverse effect on
Calogic's Business Condition.

         3.27 DISCLOSURE. Neither the representations or warranties made by
Calogic or the Stockholders in this Agreement, nor the Calogic Disclosure
Schedule or any other certificate executed and delivered by Calogic or the
Stockholders pursuant to this Agreement, when taken together, contains any
untrue statement of a material fact, or omits to state a material fact necessary
to make the statements or facts contained herein or therein not misleading in
light of the circumstances under which they were furnished.

         3.29 RELIANCE. The foregoing representations and warranties are made by
Calogic and the Stockholders with the knowledge and expectation that Parent and

         Except as set forth in the disclosure schedule of Parent dated as of
the date hereof and delivered herewith to Calogic (the "PARENT DISCLOSURE

otherwise) obligating Parent to issue shares of its capital stock or any other
securities convertible into or evidencing the right to subscribe to shares of
its capital stock.

         5.3 AUTHORITY RELATIVE TO THIS AGREEMENT. The execution, delivery and
performance of this Agreement and all other agreements contemplated hereby by
Parent and Merger Sub have been duly authorized by all necessary action of the
Boards of Directors and stockholders of Parent and Merger Sub. Certified copies
of the resolutions adopted by the Boards of Directors of Parent and Merger Sub

executed and delivered this Agreement and has, or prior to Closing, will have
duly and validly executed and delivered all other agreements contemplated hereby
to be executed by it, and each of this Agreement and such other agreements
constitutes a valid, binding and enforceable obligation of each of Parent and

         5.4 NON-CONTRAVENTION. Assuming the accuracy of the representations and
warranties of Calogic and its stockholders contained in the Agreement and the
other agreements contemplated hereby, neither the execution, delivery or
performance of this Agreement and all other agreements contemplated hereby by

transaction described herein, does or will, after the giving of notice, or the
lapse of time, or otherwise, conflict with, result in a breach of, or constitute
a default under, the Charter Documents of Parent or Merger Sub or any federal,
foreign, state or local court or administrative order or process, statute, law,
ordinance, rule or regulation, or any contract, agreement or commitment to which
Parent is a party, or under which Parent is obligated, or by which Parent or any
of the rights, properties or assets of Parent are subject or bound; result in
the creation of any Lien upon, or otherwise adversely affect, any of the rights,
properties or assets of Parent; terminate, amend or modify, or give any party
the right to terminate, amend, modify, abandon or refuse to perform or comply
with, any contract, agreement or commitment to which Parent is a party, or under
which Parent is obligated, or by which Parent or any of the rights, properties
or assets of Parent are subject or bound; or accelerate, postpone or modify, or
give any party the right to accelerate, postpone or modify, the time within
which, or the terms and conditions under which, any liabilities, duties or
obligations are to be satisfied or performed, or any rights or benefits are to

Commission applicable thereto and has been prepared in accordance with generally
accepted accounting principles applied on a consistent basis (except as may be
indicated therein or in the notes thereto) and fairly presents the financial

and except as described in Section 5.5 of the Parent Disclosure Schedule).

         5.6 VALIDITY OF PARENT MERGER SHARES. The Parent Merger Shares to be
issued in the Merger will, when issued, be, validly issued, fully paid and

and all other agreements contemplated hereby by Parent and Merger Sub or the
consummation of the Merger or any other transaction described herein.

         5.8 ABSENCE OF CERTAIN CHANGES OR EVENTS. Since September 30, 1999,

stop transfer instructions to the transfer agent for Parent Common Shares
consistent with the terms of the Investment Agreements.

         8.2 LEGAL CONDITIONS TO THE MERGER. Each of Parent, Merger Sub, Calogic
and the Stockholders will use all reasonable best efforts to take actions
necessary to comply promptly with all legal requirements which may be imposed on
it with respect to the Merger. Each of Parent, Merger Sub, Calogic and the
Stockholders will use all reasonable best efforts to take all actions to obtain
(and to cooperate with the other parties in obtaining) any consent required to
be obtained or made by Calogic, Merger Sub, or Parent in connection with the
Merger, or the taking of any action contemplated thereby or by this Agreement.

         8.3 EMPLOYEE BENEFITS. Nothing contained herein will be considered as
requiring Calogic or Parent to continue any specific plan or benefit, or to
confer upon any employee, beneficiary, dependent, legal representative or
collective bargaining agent of such employee any right or remedy of any nature
or kind whatsoever under or by reason of this Agreement, including without
limitation any right to employment or to continued employment for any specified
period, at any specified location or under any specified job category, except as

expenses of Calogic prior to Closing and provide Parent with a copy of such

any further action is reasonably necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation with full title

to this Agreement will take all such necessary action. Without limiting the

transactions contemplated under this Agreement, to the attorneys, advisors and
accountants of the parties hereto, or except as Parent or Calogic determines in
good faith to be required by applicable law) without the prior written agreement
of Parent and Calogic. In the event of any disclosure required by law, Parent
and Calogic will consult each other as to the contents thereof prior to making
such disclosure to the extent permitted by law.

         8.7 CONFIDENTIALITY. Calogic and Parent have entered into a Mutual
Non-Disclosure and Confidentiality Agreement dated June 17, 1999 as amended (the
"Non-Disclosure Agreement") concerning each party's obligations to protect the
confidential information of the other party. Calogic and Parent each hereby
affirm each of their obligations under such agreement. If this Agreement is
terminated in accordance with Article XI hereof, Parent will, and will cause its
accountants, counsel and other representatives to deliver to Calogic all
documents and other material, and all copies thereof, obtained by Parent or on
its behalf from Calogic in connection with this Agreement, whether so obtained
before or after the execution hereof, and will not disclose any such information
or documents to any third parties or make any use of such. If this Agreement is
terminated in accordance with Article XI hereof, Calogic will, and will cause
its accountants, counsel and other representatives to, deliver to Parent all
documents and other material, and all copies thereof, obtained by Calogic or on
its behalf or by a Stockholder from Parent in connection with this Agreement,
whether so obtained before or after the execution hereof, and will not disclose
any such information or documents to any third parties or make any use of such.

         8.8 POOLING.

                  (a) Parent, the Merger Sub, Calogic and each of Stockholders
will use all reasonable best efforts, will cooperate fully and will take all
actions as are reasonably necessary to allow the

                                      -31-

<PAGE>   38
Merger and other transactions contemplated by this Agreement to be accounted
for as a "pooling of interests" in accordance with United States generally
accepted accounting principles which will be acceptable to the Commission.

                  (b) Calogic has delivered to Parent prior to the date of this
Agreement a letter that identifies all persons who it believes (based on the
advice of counsel) may be "affiliates" of Calogic, as such term is used in Rule
145 under the Securities Act and applicable accounting pronouncements of the
Commission (each such Person, an "CALOGIC AFFILIATE"). Each such Calogic
Affiliate has executed and delivered to Parent a written agreement (an
"AFFILIATE AGREEMENT") in the form of EXHIBIT 8.8 hereto to the effect that such
Calogic Affiliate (i) has not made and will not make any disposition of any
shares of Calogic Common Stock or other securities of Calogic in the 30-day
period prior to the Effective Time, and (ii) will not make any disposition of
any of the Parent Merger Shares to be received by such Person after the
Effective Time until Parent shall have publicly released a report including the
combined financial results of Parent and Calogic for a period of at least 30
days of combined operations of Parent and Calogic.

         8.9 HART-SCOTT-RODINO FILING. If and to the extent applicable, Parent,
Calogic and each Stockholder agree to file, and to cause any other Person
obligated to do so as a result of such person's stock holdings in Parent or
Calogic, a Notification and Report Form in accordance with the notification
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the
rules and regulations thereunder (collectively, the "H-S-R ACT") with the
Antitrust Division of the United States Department of Justice and the Federal
Trade Commission within 10 business days of the date hereof and to use its and
their reasonable best efforts to achieve the prompt termination or expiration of
the waiting period or any extension thereof provided for under the HSR Act as a
prerequisite to the consummation of the transactions provided for herein.

         8.10 ENVIRONMENTAL MATTERS. Parent has , engaged Levine-Fricke, Inc.
(the "Environmental Consultant") to do an "environmental site assessment" (the
"Environmental Assessment Report") on Calogic's premises in Freemont and
Pleasanton, California. Calogic agrees to provide reasonable access to Parent
and Environmental Consultant to such premises to permit the preparation of the
Environmental Assessment Report after Calogic has approved the engagement letter
with Environmental Consultant (which approval shall not be unreasonably
withheld) in respect of such Environmental Assessment Report.

         Parent agrees to cause such report to be completed as soon as possible,
and in no event later than November 15, 1999. In the event such report indicates
that environmental contamination exists at such premises, then prior to the
Closing Date the parties hereto shall negotiate in good faith as to whether
Calogic will be liable for the costs of remediating any such contamination and
to reduce the number of Parent Merger Shares (valued at the Parent Average
Closing Price) to reflect a reasonable estimate of the liability to Calogic for
the cost of remediating such contamination; provided, however, that in the event
it is not reasonably likely that Calogic would actually be held liable for any
of the costs of remediating such contamination, then no such reduction shall be
made; provided, further, that such reduction shall reflect Calogic's share of
the cost of any such remediation reduced by the liability of any other parties
which may reasonably be determined to share in liability for such remediation
costs or by any anticipated recovery on any available insurance.

operation of all or any portion of Calogic's business or assets, or to compel

however, that the inclusion of this condition will not be construed in any way
as excusing any of the Stockholders from fulfilling their covenant in Section
6.13.

                  (e) ESCROW AND REGISTRATION RIGHTS AGREEMENTS. Parent shall
have duly executed and delivered the Escrow Agreement and the Registration

or the Stockholders as a result of the transactions contemplated by this
Agreement or (ii) restricting in any way the receipt, ownership, or ability to
dispose of the consideration to be received by any stockholder of Calogic in the

                                    ARTICLE X

                                 INDEMNIFICATION


         10.1 INDEMNIFICATION RELATING TO AGREEMENT. Subject to Sections 10.4
and 10.6, the Stockholders and, as an integral term of the Merger, all other
stockholders of Calogic who accept the Parent Merger Shares and execute the
Escrow Agreement (which is a condition to receiving such consideration), jointly
and severally, hereby agree to defend, indemnify and hold Parent harmless from
and against, and to reimburse Parent with respect to, any and all losses,
damages, liabilities, claims, judgments, settlements, fines, costs and expenses
(including reasonable attorneys' fees), determined as provided in Section 10.4
("INDEMNIFIABLE AMOUNTS"), of every nature whatsoever incurred by Parent (which
will be deemed to include any of the foregoing incurred by the Surviving
Corporation) by reason of or arising out of or in connection with (i) any
breach, or any claim (including claims by parties other than Parent) that
constitutes a breach, by Calogic or any of the Stockholders of any
representation or warranty of Calogic or the Stockholders contained in this
Agreement or in any certificate or other document delivered to Parent pursuant
to this Agreement, other than any breach or related claim taken or not taken at
the written direction of or after consultation with and written concurrence of
Parent, (ii) the failure, partial or total, of Calogic or any of the
Stockholders to perform any agreement or covenant required by this Agreement to
be performed by it or them other than any breach or related claim taken or not
taken at the written direction of or after consultation with and written
concurrence of Parent and (iii) any federal or state Tax liability, or asserted
liability, of Calogic attributable to periods (or any portion thereof) ending on
or prior to the Closing but only to the extent such liabilities were not accrued
for on the Balance Sheet. The foregoing obligations to indemnify Parent will be
determined without regard to any right to indemnification to which any Person
may have in his or her capacity as an officer, director, employee, agent or any
other capacity of Calogic, and no stockholder of Calogic will be entitled to any
indemnification from Calogic or the Surviving Corporation for amounts paid
hereunder. There will be no right of contribution or subrogation from Parent or
the Surviving Corporation for indemnification payments made by or for the
account of the Stockholders.

                                      -36-

<PAGE>   43


         10.2 THIRD PARTY CLAIMS. With respect to any claims or demands by third
parties as to which Parent may seek indemnification hereunder, other than claims
or demands covered by Section 10.3, whenever Parent will have received a written
notice that such a claim or demand has been asserted or threatened, Parent will
promptly notify the "Indemnification Representative" (as designated in the
Escrow Agreement) of such claim or demand and of the facts within Parent's
knowledge that relate thereto within a reasonable time after receiving such
written notice. The Indemnification Representative will then have the right to
defend, contest, negotiate or settle any such claim or demand through counsel of
his own selection, reasonably satisfactory to Parent, and solely at the
Stockholders' own cost and expense, which costs and expenses will be payable out
of the property being held pursuant to the Escrow Agreement. Notwithstanding the
preceding sentence, the Indemnification Representative will not settle,
compromise, or offer to settle or compromise any such claim or demand without
the prior written consent of Parent, which consent will not be unreasonably
withheld. Without limiting Parent's rights to object for other reasons, Parent
may object to a settlement or compromise which includes any provision which in
its reasonable judgment may have an adverse impact on or establish an adverse
precedent for the Business Condition of Parent or any of its Subsidiaries. If
the Indemnification Representative gives notice to Parent within twenty (20)
calendar days after Parent has notified the Indemnification Representative that
any such claim or demand has been made in writing, that the Indemnification
Representative elects to have Parent defend, contest, negotiate, or settle any
such claim or demand, then Parent will have the right to contest and/or settle
any such claim or demand and seek indemnification pursuant to this Article X as
to any Indemnifiable Amounts; provided, however, that Parent will not settle,
compromise, or offer to settle or compromise any such claim or demand without
the prior written consent (which may include a general or limited consent) of
the Indemnification Representative, which consent will not be unreasonably
withheld. If the Indemnification Representative fails to give written notice to
Parent of his intention to contest or settle any such claim or demand within
twenty (20) calendar days after Parent has notified the Indemnification
Representative that any such claim or demand has been made in writing, or if any
such notice is given but any such claim or demand is not contested by the
Indemnification Representative within a reasonable time thereafter, Parent will
have the right to contest and/or settle any such claim or demand in its sole
discretion and seek indemnification pursuant to this Article X as to any
Indemnifiable Amounts.

         10.3 TAX CONTESTS. Notwithstanding any of the foregoing, Parent will
have the right to conduct any Tax audit or other Tax contest relating to the
Surviving Corporation. Parent will conduct any such Tax audit or other Tax
contest in good faith. With respect to any matters relating to such Tax audits
or other Tax contests as to which Parent may seek indemnification hereunder,
Parent shall consult with the Indemnification Representative and allow him to
comment before taking any position or making any written submission with any
Governmental Entity with regard to any Indemnifiable matter.

         10.4 LIMITATIONS. Notwithstanding any other provision in this Article
X, Parent will be entitled to indemnification only to the extent that the
aggregate Indemnifiable Amounts (which shall be determined for all purposes of
this Article X disregarding any qualification in any representation or warranty
as to "materially" or "material") exceed Five Hundred Thousand Dollars
($500,000) (the "THRESHOLD AMOUNT"). The aggregate amount to which Parent will
be entitled to be indemnified will not exceed a dollar amount equal to ten
percent (10%) of Parent Merger Shares valued at the Parent Average Closing
Price, and the liability of any single Stockholder for indemnification
obligations shall be limited to such Stockholder's pro rata share of any
Indemnifiable Amounts based on the number of

                                      -37-

<PAGE>   44


Parent Merger Shares received by such Stockholder relative to the aggregate
number of Parent Merger Shares; provided, however, that the limitation on the
obligations of any Person for Indemnifiable Amounts arising out of criminal
activity or fraud or willful misstatements or omissions by Calogic or such
Person will be a Dollar amount equal to the aggregate number of Parent Merger
Shares received by such Person valued at the Parent Average Closing Price.
Parent will first seek reimbursement of any Indemnifiable Amounts pursuant to
the provisions of the Escrow Agreement, but may seek indemnification hereunder
with respect to any Indemnifiable Amounts after the termination of the Escrow
Agreement, subject to Section 10.6. During the term of the Escrow Agreement,
Parent's sole remedy will be a claim pursuant to the Escrow Agreement. To the
extent Parent is paid an amount on account of an Indemnifiable matter in excess
of the limitation set forth above, Parent will promptly remit such excess amount
to the party entitled thereto.

         10.5 BINDING EFFECT. The indemnification obligations contained in this
Article X are an integral part of this Agreement and the Merger in the absence
of which Parent would not have entered into this Agreement.

         10.6 TIME LIMIT. The representations, warranties, covenants and
agreements of Calogic and the Stockholders set forth in this Agreement will
survive the Closing and the consummation of the transactions contemplated by
this Agreement, but, absent fraud, any claims with respect thereto may be made
only on or before the first yearly anniversary of the date of this Agreement;
provided, however, that claims relating to the representations and warranties in
Section 3.6 may be made only on or before the date Parent publishes financial
results covering at least 30 days combined operations of Parent and Calogic.

         10.7 SOLE REMEDY. Notwithstanding any other provision in this Agreement
to the contrary, except as provided for in the Holder Agreement of even date
herewith, among Parent, Calogic and Manuel Del Arroz (the "Holder Agreement")
the provisions of this Article X and the provisions of the Escrow Agreement will
be the sole and exclusive remedy of (and corresponding liability of any
stockholder of Calogic, in such stockholder's capacity as such, to) Parent,
Merger Sub and the Surviving Corporation for any damage, claim, cause of action
or right of any nature arising out of or relating to this Agreement, the
certificates or other documents executed or delivered herewith, or the
transactions contemplated hereby; provided, however, that nothing in this
Agreement or the Escrow Agreement will be deemed to limit any right or remedy
for criminal activity or fraud, or willful misstatements or omissions, or
breaches of covenants or inaccuracies in any representations or warranties set
forth in any other agreement contemplated by this Agreement, including any
Investment Agreement, Affiliate Agreement, the Employment Agreement, the Non
solicitation Agreement, the Registration Rights Agreement or the Holder
Agreement.

<PAGE>   45


         10.1A INDEMNIFICATION RELATING TO AGREEMENT. Subject to Sections 10.2A
and 10.3A, Parent hereby agrees to defend, indemnify and hold the Stockholders
and all other stockholders of Calogic who accept the Parent Merger Shares (the
"INDEMNIFIED STOCKHOLDERS") harmless from and against, and to reimburse the
Indemnified Stockholders with respect to, any and all losses, damages,
liabilities, claims, judgments, settlements, fines, costs and expenses
(including reasonable attorneys' fees), determined as provided in Section 10.2A
("STOCKHOLDER INDEMNIFIABLE AMOUNTS"), of every nature whatsoever incurred by
the Indemnified Stockholders by reason of or arising out of or in connection
with (i) any breach, or any claim that constitutes a breach, by Parent or Merger
Sub of any representation or warranty of Parent or Merger Sub contained in this
Agreement or in any certificate or other document delivered by Parent or Merger
Sub to the Indemnified Stockholders or Calogic pursuant to this Agreement, other
than any breach or related claim taken or not taken at the written direction of
or after consultation with and written concurrence of Calogic or the Indemnified
Stockholders, and (ii) the failure, partial or total, of Parent or Merger Sub to
perform any agreement or covenant required by this Agreement to be performed by
it other than any breach or related claim taken or not taken at the written
direction of or after consultation with and written concurrence of Calogic or
the Indemnified Stockholders.

         10.2A LIMITATIONS. Notwithstanding any other provision in this Article
XA, the Indemnified Stockholders will be entitled to indemnification only to the
extent that the aggregate Stockholder Indemnifiable Amounts (which shall be
determined for all purposes of this Article XA disregarding any qualification in
any representation or warranty as to "materially" or "material") exceed Five
Hundred Thousand Dollars ($500,000) (the "STOCKHOLDER THRESHOLD AMOUNT"). The
aggregate amount to which the Indemnified Stockholders will be entitled to be
indemnified will not exceed a dollar amount equal to ten percent (10%) of Parent
Merger Shares valued at the Parent Average Closing Price, provided, however,
that the limitation on the obligations of Parent for Stockholder Indemnifiable
Amounts arising out of criminal activity or fraud or willful misstatements or
omissions by Parent or Merger Sub will be a dollar amount equal to the aggregate
number of Parent Merger Shares valued at the Parent Average Closing Price. To
the extent an Indemnified Stockholder is paid an amount on account of an
Indemnifiable matter in excess of the limitation set forth above, such
Indemnified Stockholder will promptly remit such excess amount to Parent.

         10.3A TIME LIMIT. The representations, warranties, covenants and
agreements of Parent and Merger Sub set forth in this Agreement will survive the
Closing and the consummation of the transactions contemplated by this Agreement,
but any claims with respect thereto may be made only on or before the first
yearly anniversary of the date of this Agreement; provided, however, that claims
alleging fraud or willful misstatements or omissions of Parent or Merger Sub may
be made only on or before the third yearly anniversary of the Closing Date.

         10.4A SOLE REMEDY. Notwithstanding any other provision in this
Agreement to the contrary, the provisions of this Article XA will be the sole
and exclusive remedy of (and corresponding liability of Parent and Merger Sub)
the Indemnified Stockholders for any damage, claim, cause of action or right of
any nature arising out of or relating to this Agreement, the certificates or
other documents executed or delivered herewith, or the transactions contemplated
hereby; provided, however, that nothing in this Agreement will be deemed to
limit any right or remedy for criminal activity or fraud, or willful
misstatements or omissions, or breaches of covenants or inaccuracies in any
representations or warranties set forth in any other agreement contemplated by
this Agreement, including any employment agreements or the Registration Rights
Agreement.

         11.1 MUTUAL AGREEMENT. This Agreement may be terminated at any time
prior to the Effective Time by the written consent of Parent and Calogic.

         11.2 TERMINATION BY PARENT. This Agreement may be terminated by Parent
(provided that it is not then in material breach of any representation,
warranty, covenant or agreement contained in this Agreement) alone, by means of
written notice to Calogic, if there has been a material breach by Calogic or a
Stockholder of any representation, warranty, covenant or agreement set forth in
this Agreement or other ancillary agreements, which breach would result in a
failure to satisfy the closing conditions contained in Section 9.2 and has not
been cured within five (5) business days following receipt by Calogic of notice
of such breach.

         11.3 TERMINATION BY CALOGIC. This Agreement may be terminated by
Calogic (provided that it is not then in material breach of any representation,
warranty, covenant or agreement contained in this Agreement) alone, by means of
written notice to Parent, if there has been a material breach by Parent of any
representation, warranty, covenant or agreement set forth in this Agreement or
other ancillary agreements, which breach would result in a failure to satisfy
the closing conditions contained in Section 9.3 and has not been cured within
five (5) business days following receipt by Parent of notice of such breach.

         11.4 OUTSIDE DATE. This Agreement may be terminated by Parent alone or
by Calogic alone by means of written notice if the Effective Time does not occur
on or prior to November 30, 1999; provided, however, that the right to terminate
this Agreement pursuant to the preceding clause will not be available to any
party whose failure to fulfill any obligation under this Agreement has been a
significant cause of, or resulted in, the failure of the Effective Time to occur
on or before such date.

         11.5 EFFECT OF TERMINATION. In the event of termination of this
Agreement by either Calogic or Parent as provided in this Article, this
Agreement will forthwith become void and have no effect, and there will be no
liability or obligation on the part of Parent, Calogic, Merger Sub, the
Stockholders or their respective officers or directors, except that (i) the
provisions of Sections 8.4, 8.6, 8.7 (including the provisions of the
Non-Disclosure Agreement) and 12.2 will survive any such termination and
abandonment, and (ii) no party will be released or relieved from any liability
arising from the willful breach by such party prior to termination of any of its
representations, warranties, covenants or agreements as set forth in this
Agreement.

         12.4 SEVERABILITY. If any provision of this Agreement is held to be
unenforceable for any reason, it will be modified rather than voided, if
possible, in order to achieve the intent of the parties to this Agreement to the
extent possible. In any event, all other provisions of this Agreement will be
deemed valid and enforceable to the full extent.

         12.5 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations

law or otherwise, all or any portion of its rights, obligations, or liabilities
under this Agreement without the prior written consent of Calogic, Merger Sub
and Parent, which consent may be withheld in the absolute discretion of the
party asked to grant such consent; provided however, that no such assignment
which materially adversely reflects the rights of a Stockholder will be made
without the written consent of such Stockholder. Any attempted assignment by
Merger Sub or Parent, on the one hand, or by Calogic, on the other hand, in
violation of this Section 12.6 will be voidable and will entitle Calogic or
Parent, respectively, to terminate this Agreement at its option.

         12.7 COUNTERPARTS. This Agreement may be executed in two or more
partially or fully executed counterparts each of which will be deemed an
original and will bind the signatory, but all of which together will constitute
but one and the same instrument. The execution and delivery of a Signature Page
to Agreement and Plan of Reorganization in the form annexed to this Agreement,
including a facsimile copy of the actual signature, by any party hereto who will
have been furnished the final form of this Agreement will constitute the
execution and delivery of this Agreement by such party.

<PAGE>   49


         12.8 AMENDMENT. This Agreement may not be amended except by an
instrument in writing executed by Calogic, Merger Sub and Parent; provided
however, that no such amendment which materially adversely affects the rights or
obligations of any Stockholder will be made without the written consent of such
Stockholder.

         12.9 EXTENSION, WAIVER. At any time prior to the Effective Time, any
party hereto may, to the extent legally allowed: (i) extend the time for the
performance of any of the obligations or other acts of any other party hereto to
the party extending such time, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements, covenants or conditions for the benefit of such party contained
herein. Any agreement on the part of a party hereto to any such extension or
waiver will be valid only if set forth in an instrument in writing signed on
behalf of such party.

         12.10 INTERPRETATION. When a reference is made in this Agreement to
Sections, Exhibits or Schedules, such reference will be to a Section, Exhibit or
Schedule to this Agreement unless otherwise indicated. The words "include,"
"includes," and "including" when used therein will be deemed in each case to be
followed by the words "without limitation." The table of contents, index to
defined terms, and headings contained in this Agreement are for reference
purposes only and will not affect in any way the meaning or interpretation of
this Agreement.

         12.11 KNOWLEDGE. For purposes of this Agreement, the term "KNOWLEDGE"
(including any derivation thereof such as "know" or "knowing" and regardless of
whether such word starts with an initial capital) in reference to Calogic will
mean the knowledge of the directors and executive officers of Calogic and the
Stockholders (the "Specified Individuals"). For purposes of this Agreement, a
Specified Individual shall not be deemed to have any knowledge of the inaccuracy
of any representation, warranty or other statement unless such Specified
Individual actually knows that such representation, warranty or other statement
is materially inaccurate. No knowledge shall be imputed to any Specified
Individual.

         12.12 TRANSFER, SALES, DOCUMENTARY, STAMP AND OTHER SIMILAR TAXES. Any
and all transfer, sales, documentary, stamp and other similar Taxes imposed in
connection with the transactions contemplated by this Agreement will be paid by
the stockholder of Calogic with respect to which such Tax relates. At Parent's
discretion, the amount paid to any Person pursuant to this Agreement will be
reduced by the amount of Taxes payable by such Person pursuant to this Section
12.12. Any amounts so withheld will be promptly remitted to the appropriate
taxing authority.

                                ESCROW AGREEMENT

         This Escrow Agreement (this "ESCROW AGREEMENT") is made and entered
into as of November 23, 1999 (the "EFFECTIVE TIME") by and among SIPEX
Corporation, a Massachusetts corporation ("PARENT"); Calogic, a California
corporation ("CALOGIC"); the undersigned security holders of Calogic
(collectively the "HOLDERS"); Manuel Del Arroz, as the representative of the
Holders (the "INDEMNIFICATION REPRESENTATIVE"); and State Street Bank and Trust
Company , as escrow agent for the Escrow Shares (as defined below) (the "ESCROW
AGENT").

         A. CAT Acquisition Corporation I, a Delaware corporation and wholly
owned subsidiary of Parent ("MERGER SUB"), Calogic, and certain stockholders of
Calogic (the "HOLDERS") have entered into an Agreement and Plan of
Reorganization and a Holders Agreement each dated as of October 21, 1999
(collectively, the "MERGER AGREEMENT") setting forth certain terms and
conditions pursuant to which Merger Sub is being merged into Calogic (the
"MERGER").

         B. Pursuant to Section 2.1 of the Merger Agreement, Parent Merger
Shares (as defined therein) are to be issued to the Holders.

         C. The Merger Agreement provides that three hundred and thirty thousand
(the "ESCROW AMOUNT") of the Parent Merger Shares issued for Outstanding Calogic
Shares pursuant to the Merger will be placed in an escrow account to secure
certain indemnification obligations of the Holders to Parent under the Merger
Agreement on the terms and conditions set forth therein and herein.

         D. Unless otherwise indicated herein, all terms used herein without
definition shall have the same meaning as set forth in the Merger Agreement.

         NOW THEREFORE, for and in consideration of the foregoing and the mutual
covenants and agreements contained in the Merger Agreement and in this Escrow
Agreement, the parties agree as follows:

         1.       ESTABLISHMENT OF ESCROW ACCOUNT
                  -------------------------------

                  1.1 DEPOSIT OF SHARES. Parent shall deposit as soon as
practicable on the Holders' behalf with the Escrow Agent stock certificates
representing the Escrow Shares issued pursuant to the Merger registered in the
respective names of the Holders and in the relative amounts set forth on EXHIBIT
1.1 hereto (the "INITIAL ESCROW SHARES"), together with stock transfer powers
signed in blank with guaranteed signatures. Any shares of Parent capital stock
that result from any share dividend, reclassification, stock split, subdivision
or combination of shares, recapitalization, merger or other events made with
respect to any Escrow Shares held in escrow under this Escrow Agreement
("ADDITIONAL SHARES") shall be delivered to the Escrow Agent and shall be held
by the Escrow Agent in accordance with this Escrow Agreement. Unless otherwise
indicated, as used in this Escrow Agreement, the term "ESCROW SHARES" includes
the Initial Escrow Shares and any Additional Shares. The Escrow Agent agrees to
accept delivery of the Escrow Shares and to hold such Escrow Shares in escrow in
accordance with this Escrow Agreement and to release the Escrow Shares, and all
related stock transfer powers out of escrow as provided in this Escrow
Agreement. The Escrow Agent shall be under no obligation to preserve, protect or
exercise rights in the Escrow Shares and shall be responsible only for the
taking of reasonable measures to maintain the physical safekeeping thereof.


<PAGE>   2


The Escrow Agent shall have no responsibility for the genuineness, validity,
market value, title or sufficiency for any intended purposes of the Escrow
Property.

                  1.2 DIVIDENDS; VOTING AND RIGHTS OF OWNERSHIP. Any cash
dividends, dividends payable in property or other distributions of any kind
(except for Additional Shares) made in respect of the Escrow Shares shall be
distributed currently by Parent directly to the Holders on a pro rata basis.
Each Holder shall have the right to vote the Escrow Shares held in escrow for
the account of such Holder so long as such Escrow Shares are held in escrow, and
Parent and the Escrow Agent shall take all steps necessary to allow the exercise
of such rights. While the Escrow Shares remain in the Escrow Agent's possession
pursuant to this Escrow Agreement, the Holders shall retain and shall be able to
exercise all other incidents of ownership of the Escrow Shares that are not
inconsistent with the terms and conditions hereof. Any income tax reporting
required with respect to dividends paid on the Escrow Shares shall be the
responsibility of Parent.

                  1.3 NO ENCUMBRANCE. None of the Escrow Shares or any
beneficial interest therein may be pledged, sold, assigned or transferred,
including by operation of law or by a Holder, or may be taken or reached by any
legal or equitable process in satisfaction of any debt or other liability of a
Holder, prior to the delivery of the Escrow Shares by the Escrow Agent or Parent
to such Holder pursuant to this Escrow Agreement.

                  1.4 POWER TO TRANSFER ESCROW SHARES. The Escrow Agent is
hereby granted the power to effect any transfer of the Escrow Shares provided
for in this Escrow Agreement.

         2.       RESOLUTION OF CLAIMS
                  --------------------

                  2.1 INDEMNIFICATION OBLIGATIONS. The Escrow Shares shall serve
as the first source, but not the sole source, of payment for the indemnity
obligations of the Holders under the Merger Agreement. For the purposes of this
Escrow Agreement, those obligations shall continue in accordance with the Merger
Agreement, notwithstanding the merger of Merger Sub into Calogic pursuant to the
Merger Agreement. Payment for any amount determined as provided below to be
owing to Parent under such indemnity obligations under the Merger Agreement
("DAMAGES") and any award of attorneys' fees and charges owing to Parent
pursuant to Section 2.3(c)(iv) or 11.2 of this Agreement (a "PREVAILING PARTY
AWARD") shall be made by the release of Escrow Shares to Parent (each such
payment, an "ESCROW ADJUSTMENT"), subject to the limitations set forth in
Section 10.4 of the Merger Agreement. By the execution of this Escrow Agreement,
each of the Holders agrees to be bound by the indemnification provisions set
forth in the Merger Agreement and confirms that the issuance of the Escrow
Amount of the Parent Merger Shares pursuant to the Merger Agreement is subject
to this Escrow Agreement. Notwithstanding anything to the contrary herein,
Parent shall not be entitled to receive payment of any portion of a Prevailing
Party Award which is already a part of Damages (i.e., there shall be no double
payment of legal fees). Any Escrow Adjustments and corresponding release to
Parent of Escrow Shares shall be made in proportion to each of the Holders'
interest in the Escrow Shares as of the date or dates specified and the manner
provided for in this Escrow Agreement. Each Escrow Adjustment to the Escrow
Shares shall be made by the release to Parent of Escrow Shares having an
aggregate value equal to the Damages and any Prevailing Party Award, with the
per share value of such shares being based, for all purposes under this Escrow
Agreement on the Parent Average Closing Price (adjusted for any share dividend,
reclassification, stock split, subdivision or combination of shares,
recapitalization, merger or other events) notwithstanding any changes in market
value of Parent Common Shares. In lieu of releasing any

                                      -2-

<PAGE>   3


fractional Escrow Shares, any fraction of a released Escrow Share that would
otherwise be released shall be rounded to the nearest whole Escrow Share.

                  2.2 NOTICE OF CLAIMS. Promptly after the receipt by Parent of
notice or discovery of any claim, damage, or legal action or proceeding giving
rise to indemnification rights under the Merger Agreement, after giving effect
to the Threshold Amount (as defined in the Merger Agreement) (a "CLAIM") Parent
shall give the Indemnification Representative written notice of such Claim and
shall provide a copy of such notice to the Escrow Agent. Each notice of a Claim
by Parent (a "NOTICE OF CLAIM") shall be in writing and shall be delivered on or
before the Release Date (as defined in Section 3.1 below). Notice of any Claim
shall include the Parent Average Closing Price and in no event shall the Bank be
obligated to determine such price.

                  2.3 RESOLUTION OF CLAIMS. Any Notice of Claim received by the
Indemnification Representative and the Escrow Agent pursuant to Section 2.2
above shall be resolved as follows:

                           (a) UNCONTESTED CLAIMS. In the event that the
Indemnification Representative does not contest a Notice of Claim (an
"UNCONTESTED CLAIM") in writing within thirty (30) calendar days, as provided
below in Section 2.3(b), Parent may deliver to the Escrow Agent, with a copy to
the Indemnification Representative, a written demand by Parent (a "PARENT
DEMAND") stating that a Notice of Claim has been given as required in this
Escrow Agreement and that no notice of contest has been received from the
Indemnification Representative during the period specified in this Escrow
Agreement and further setting forth the proposed Escrow Adjustments to be made
in accordance with this Section 2.3(a). It is provided, however, that within
thirty (30) calendar days after receipt of the Parent Demand, the
Indemnification Representative may object in a written notice delivered to
Parent and the Escrow Agent to the computations or other administrative matters
relating to the proposed Escrow Adjustments (but may not object to the validity
or amount of the Claim previously disclosed in the Notice of Claim), whereupon
neither the Escrow Agent nor Parent shall make any of the Escrow Adjustments
until either: (i) Parent and the Indemnification Representative shall have given
the Escrow Agent written notice setting forth agreed Escrow Adjustments, or (ii)
the matter is resolved as provided in Sections 2.3(b) and 2.3(c). Upon
satisfaction of the foregoing, the Escrow Agent, as directed in writing by
Parent, and Parent shall promptly take all steps to implement the final Escrow
Adjustments.

                           (b) CONTESTED CLAIMS. In the event that the
Indemnification Representative gives written notice to Parent and the Escrow
Agent contesting all or a portion of a Notice of Claim (a "CONTESTED Claim")
within the 30-day period provided above, matters that are subject to third party
claims against Parent or Calogic in a litigation or arbitration shall await the
final decision, award or settlement of such litigation or arbitration, while
matters that arise between Parent on the one hand and Calogic and/or the Holders
on the other hand, including any disputes regarding performance or
nonperformance of a party's obligations under this Escrow Agreement ("ARBITRABLE
CLAIMS") shall be settled in accordance with Section 2.3(c) below. Any portion
of a Notice of Claim that is not contested or is subsequently settled by Parent
and the Indemnification Representative shall be resolved as set forth above in
Section 2.3(a), provided that in the case of a settlement the value of Escrow
Shares shall equal the Parent Average Closing Price notwithstanding any change
in the market value of Parent Common Shares. If written notice is received by
the Escrow Agent that a Notice of Claim is contested by the Indemnification
Representative, then the Escrow Agent shall hold hereunder after what would
otherwise be the Release Date (as defined in Section 3.1 below), the number of
Escrow Shares specified in the Release Notice or as otherwise provided in
Section 3.1, until the earlier of: (i) receipt of a settlement agreement
executed by Parent and the Indemnification Representative setting forth a

                                      -3-

<PAGE>   4


resolution of the Notice of Claim and the Escrow Adjustments; (ii) receipt of a
written notice from Parent (a "PARENT DISTRIBUTION NOTICE") attaching a copy of
the final award or decision of the arbitrator and setting forth the Escrow
Adjustments (Parent shall at the same time provide a copy of the Parent
Distribution Notice to the Indemnification Representative); or (iii) receipt of
a written notice from the Indemnification Representative (a "REPRESENTATIVE
DISTRIBUTION NOTICE") attaching a copy of the final award or decision of the
arbitrator that no Escrow Adjustments are to be made as a result of such award
(the Indemnification Representative shall at the same time provide a copy of the
Representative Distribution Notice to Parent). If the earliest of the three
events described in the preceding sentence is (i) or (ii), the Escrow Agent
shall, within twenty (20) calendar days of receipt of the settlement agreement
or the Parent Distribution Notice, as applicable, (a) release to Parent the
number of Escrow Shares specified in the Escrow Adjustments and (b) if the
Release Date has occurred, and there are no remaining unresolved Contested
Claims, release to the Holders the balance of the Escrow Shares and the related
stock transfer powers. If the earliest of the three events described above is
(iii) and the Release Date has occurred, and there are no remaining unresolved
Contested Claims, the Escrow Agent shall, within twenty (20) calendar days of
receipt of the Representative Distribution Notice, release to the Holders the
Retained Escrow (as defined in Section 3.1), in accordance with the Holders'
interests therein, provided that if the Release Date has not occurred the Escrow
Shares shall continue to be held pursuant to the terms of this Agreement. If the
award or decision of the arbitrator concludes that Escrow Shares are to be
released to Parent either in satisfaction of Damages or as Prevailing Party
Awards, the arbitrator shall specify the number of Escrow Shares to be so
released to Parent either in the arbitrator's final award or decision or a
supplementary report or finding. In the event that the Escrow Agent institutes
an action for interpleader in accordance with Section 4.6 of this Escrow
Agreement as a result of a dispute between the parties, the parties hereby agree
to jointly seek to stay such interpleader action pending the resolution of any
arbitration commenced by the parties or any dispute pursuant to this Section
2.3(b) and Section 2.3(c).

                           (c)  ARBITRATION.

                                    (i) ARBITRATION RULES. Any Arbitrable Claim,
and any dispute between the Holders and Parent under this Escrow Agreement,
shall be submitted to final and binding arbitration before a single arbitrator
in Boston, Massachusetts in accordance with the commercial arbitration rules of
the American Arbitration Association.

                                    (ii) BINDING EFFECT. The final decision of
the arbitrator shall be furnished in writing to the Escrow Agent, the
Indemnification Representative, the Holders and Parent and will constitute a
conclusive determination of the issue in question, binding upon the Holders, the
Indemnification Representative and Parent. The arbitrator shall have the
authority to grant any equitable and legal remedies that would be available in
any judicial proceeding instituted to resolve an Arbitrable Claim. Any judgment
upon the award rendered by the arbitrator may be entered in any court having
jurisdiction over the subject matter thereof.

                                    (iii) COMPENSATION OF ARBITRATOR. The
arbitrator will be compensated for his or her services, as provided below in
Section 2.3(c)(iv), in accordance with the commercial arbitration rules of the
American Arbitration Association.

                                    (iv) PAYMENT OF COSTS. Subject to the
limitations in the Merger Agreement, the substantially prevailing party in any
arbitration shall be entitled to an award of attorneys' fees and costs, and all
costs of arbitration, including those provided for above, will be paid by the
losing party, subject in each case to a determination by the arbitrator as to
which party is the

                                      -4-

<PAGE>   5


substantially prevailing party and the amount of such fees and costs to be
allocated to such party and subject to the terms of Section 2.3(c)(iii). Any
amounts payable to Parent by or on account of the Holders under this subsection
will be reimbursed as if the amount of such awarded fees and expenses were an
Uncontested Claim.

                                    (v) TERMS OF ARBITRATION. The arbitrator
chosen in accordance with these provisions shall not have the power to alter,
amend or otherwise affect the terms of these arbitration provisions or the
provisions of this Escrow Agreement, the Merger Agreement or any other documents
that are executed in connection therewith.

                                    (vi) EXCLUSIVE REMEDY. Arbitration or
mediation under this Section 2.3(c) shall be the sole and exclusive remedy of
the parties for any Arbitrable Claim arising out of this Escrow Agreement.

         3.       RELEASE FROM ESCROW
                  -------------------

                  3.1 RELEASE OF ESCROW SHARES. The Escrow Shares and all
related stock transfer powers shall be released by the Escrow Agent and Parent
as soon as practicable, taking into account the notices to be delivered under
this Section 3.1, after the publication of Parent's audited financial results
for the year ended December 31, 1999 (the "RELEASE DATE") LESS: (a) any Escrow
Shares delivered to or deliverable to Parent in satisfaction of Uncontested
Claims or Contested Claims which have been settled by the parties hereto, and
(b) any of the Escrow Shares subject to delivery to Parent in accordance with
Section 2.3(b) with respect to any then pending Contested Claims. Parent shall
give written notice to the Indemnification Representative and the Escrow Agent
of the publication of Parent's audited financial results for the year ended
December 31, 1999. Promptly, and no later than seven (7) of the Escrow Agent's
business days ("BUSINESS DAYS") after the Release Date, Parent and the
Indemnification Representative shall deliver to the Escrow Agent a written
notice (a "RELEASE NOTICE") setting forth the number of Escrow Shares to be
released by the Escrow Agent and Parent (the "RELEASED ESCROW") including the
number of Escrow Shares to be released to each Holder and the number of Escrow
Shares to be retained as provided in this Section 3.1 (the "RETAINED ESCROW")
Parent and the Indemnification Representative shall make a good faith effort to
agree on a reasonable portion of the Escrow Shares to retain for pending
Contested Claims and Prevailing Party Awards and related expenses. Until such
agreement is reached, or a determination is made in accordance with Section
2.3(c), the remaining Escrow Shares shall be the Retained Escrow. The Released
Escrow shall be released to the Holders in proportion to their respective
interests in the Initial Escrow Shares. In lieu of releasing any fractional
Escrow Shares, any fraction of a released Escrow Share that would otherwise be
released shall be rounded to the nearest whole Escrow Share. The Release Notice
shall instruct the Escrow Agent to deliver (by registered mail or overnight
courier service) to each Holder evidence of ownership of the number of Escrow
Shares in the names of the appropriate Holders. The Escrow Agent shall not be
required to take such action until the Escrow Agent has received the Release
Notice executed by Parent and the Indemnification Representative or, in the
event Parent and the Indemnification Representative fail to execute and deliver
a jointly approved Release Notice, a final award or decision which specifies the
distribution of the Escrow Shares.

                  3.2 RELEASE OF RETAINED ESCROW. Upon the resolution of
Contested Claims as provided for in Section 2.3(b), the Retained Escrow shall be
subject to release by the Escrow Agent to Parent and/or to the Holders in
accordance with Section 2.3(b), this Section and as otherwise provided for in
this Escrow Agreement. The Escrow Agent, Parent and the Indemnification
Representative shall cause the transfer agent to transfer to Parent the number
of Escrow Shares to be released to Parent

pursuant to Section 2.3(b) and transfer the number of Escrow Shares that are to
be either distributed to the Holders pursuant to Section 3.1 or further retained
by the Escrow Agent pending the resolution of Contested Claims and/or Prevailing
Party Awards. Any Escrow Shares released from escrow to Parent shall be subject
to cancellation by Parent without requiring Parent to pay any consideration
whatsoever in receipt thereof to Calogic or any of the Holders.

                  3.3 EXPENSES OF INDEMNIFICATION REPRESENTATIVE. The
Indemnification Representative shall be entitled to be reimbursed his reasonable
out-of-pocket expenses and the reasonable fees and disbursements of counsel
retained by him. Such reimbursements shall be treated as an Uncontested Claim on
a pro rata basis among the contributors to the Escrow Shares (based on the
percentages set forth on EXHIBIT 1.1), for all services performed pursuant to
the Merger Agreement and this Escrow Agreement; provided, however, that payment
of any Escrow Adjustment shall take priority over payments to the
Indemnification Representative, as provided herein. The Escrow Agent shall
follow the joint written instructions of the Indemnification Representative and
Parent concerning the release of Escrow Shares relating to the reimbursement of
the Indemnification Representative. If upon termination of this Agreement, the
Indemnification Representative shall not have received the reimbursements to
which he is entitled hereunder, then the Indemnification Representative shall be
entitled to reimbursement from the Holders on a joint and several basis.

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

                  4.1 DUTIES. The duties and responsibilities of the Escrow
Agent hereunder shall be entirely administrative and not fiduciary or
discretionary in nature and shall be determined solely by the express provisions
of this Escrow Agreement and no duties shall be implied. The Escrow Agent shall
be obligated to act only in accordance with written instructions received by it
as provided in this Escrow Agreement and is authorized hereby to comply with any
orders, judgments, or decrees of any court with or without jurisdiction and
shall not be liable as a result of its compliance with the same. Parent, Calogic
and the Holders agree that, notwithstanding anything to the contrary herein, the
Escrow Agent shall not be responsible for any of the other agreements referred
to or described herein (including, without limitation, the Merger Agreement) or
for determining or compelling compliance therewith, and shall not otherwise be
bound thereby.

                  4.2 LEGAL OPINIONS. As to any questions arising in connection
with the administration of this Escrow Agreement, the Escrow Agent may rely
absolutely upon the joint instruction of Parent and the Indemnification
Representative or the opinions given to the Escrow Agent by its outside counsel
and shall be free of liability for acting or refraining from acting in reliance
on such opinions.

                  4.3 SIGNATURES. The Escrow Agent may rely absolutely upon the
genuineness and authorization of the signature and purported signature of any
party upon any instruction, notice, release, receipt or other document delivered
to it pursuant to this Escrow Agreement.

                  4.4 RECEIPTS AND RELEASES. The Escrow Agent may, as a
condition to the release or disposition of securities as provided herein,
require from the payee or recipient a receipt therefor and, upon final payment
or disposition, a release of the Escrow Agent from any liability arising out of
its execution or performance of this Escrow Agreement, such release to be in a
form reasonably satisfactory to the Escrow Agent.

                  4.5 REFRAIN FROM ACTION. The Escrow Agent shall be entitled to
refrain from taking any legal or other action contemplated by this Escrow
Agreement in the event it becomes aware of any dispute between Calogic, the
Holders and Parent as to any material facts or as to the happening of any event
precedent to such action and the Escrow Agent shall be entitled to refrain from
taking any action that might in its judgement involve or cause it to incur any
expense or liability unless it shall first have been furnished with acceptable
indemnification.

                  4.6 INTERPLEADER. If any controversy arises between the
parties hereto or with any third person, the Escrow Agent shall not be required
to determine the same or to take any action, but the Escrow Agent in its
discretion may institute such interpleader or other proceedings in connection
therewith as the Escrow Agent may deem proper, and in following either course,
the Escrow Agent shall not be liable.

                  4.7 OTHER PROVISIONS. The Escrow Agent may rely upon and shall
be protected in acting or refraining from acting upon any written notice,
instruction or request furnished to it hereunder and believed by it to be
genuine and to have been signed or presented by the proper party or parties. The
Escrow Agent shall be under no duty to inquire into or investigate the validity,
accuracy or content of any such document. The Escrow Agent shall be not be
liable for any action taken or omitted by it in good faith unless a court of
competent jurisdiction determines that the Escrow Agent's willful misconduct was
the primary cause of a loss to the Parent, the Indemnification Representative,
or the Holders. In the administration of this Escrow Agreement, the Escrow Agent
may execute any of its powers and perform its duties hereunder directly or
through agents or attorneys and may, consult with counsel, accountants and other
skilled persons to be selected and retained by it. The Escrow Agent shall not be
liable for anything done, suffered or omitted in good faith by it in accordance
with the advice or opinion of any such counsel, accountants or other skilled
persons.

                  4.8 Sale of Escrow Shares. Notwithstanding anything herein to
the contrary, the Escrow Agent shall have no duty to sell the Escrow Shares
hereunder.

         5.       INDEMNIFICATION
                  ---------------

                  5.1 WAIVER AND INDEMNIFICATION. Parent, Calogic, the
Indemnification Representative and the Holders agree to and hereby do waive any
suit, claim, demand or cause of action of any kind which they may have or may
assert against the Escrow Agent arising out of or relating to the execution or
performance by the Escrow Agent of this Escrow Agreement, unless such suit,
claim, demand or cause of action is based upon the willful neglect, gross
negligence or bad faith of the Escrow Agent. Parent, Calogic and the Holders
further agree, jointly and severally, to indemnify and hold Escrow Agent and its
directors, officers, agents and employees (collectively, the "INDEMNITEES")
harmless from and against any and all claims, liabilities, losses, damages,
fines, penalties, and expenses, including out-of-pocket, incidental expenses,
reasonable legal fees and expenses (including the reasonable fees and expenses
of not more than one outside counsel), and the allocated costs and expenses of
in-house counsel and legal staff ("LOSSES") that may be imposed on, incurred by,
or asserted against, the Indemnitees or any of them for following any
instructions or other directions upon which the Escrow Agent is authorized to
rely pursuant to the terms of this Escrow Agreement, provided the Escrow Agent
has not acted with gross negligence, willful neglect or bad faith. In addition,
to and not in limitation of the immediately preceding sentence, Parent, Calogic
and the Holders also agree, jointly and severally, to indemnify and hold the
Indemnitees and each of them harmless from and against any and all Losses that
may be imposed on, incurred by, or asserted against the Indemnitees or any of
them in connection with or arising out of the Escrow Agent's performance

                                      -7-

<PAGE>   8


under this Escrow Agreement, provided the Escrow Agent has not acted with gross
negligence, willful neglect or bad faith. The provisions of this Section 5.1
shall survive the termination of this Escrow Agreement and the resignation or
removal of the Escrow Agent for any reason. Anything in this Escrow Agreement to
the contrary notwithstanding, in no event shall the Escrow Agent be liable for
special, indirect, punitive or consequential loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Escrow Agent
has been advised of such loss or damage and regardless of the form of action.

                  5.2 CONDITIONS TO INDEMNIFICATION. In case any litigation is
brought against the Escrow Agent in respect of which indemnification may be
sought hereunder, the Escrow Agent shall give prompt notice of that litigation
to the parties hereto, and the parties upon receipt of that notice shall have
the obligation and the right to assume the defense of such litigation with
counsel reasonably satisfactory to the Escrow Agent; provided that failure of
the Escrow Agent to give that notice shall not relieve the parties hereto from
any of their obligations under this Section 5 unless that failure prejudices the
defense of such litigation by said parties. At its own expense, the Escrow Agent
may employ separate counsel and participate in the defense. The parties hereto
shall not be liable for any settlement without their respective consents.

         6.       ACKNOWLEDGMENT BY THE ESCROW AGENT
                  ----------------------------------

         By execution and delivery of this Escrow Agreement, the Escrow Agent
acknowledges that the terms and provisions of this Escrow Agreement are
acceptable and it agrees to carry out the provisions of this Escrow Agreement on
its part.

         7.       RESIGNATION OR REMOVAL OF ESCROW AGENT; SUCCESSOR
                  -------------------------------------------------

                  7.1      RESIGNATION AND REMOVAL.

                           7.1.1 NOTICE. The Escrow Agent may resign as such
following the giving of thirty (30) days' prior written notice to the other
parties hereto. Similarly, the Escrow Agent may be removed and replaced
following the giving of thirty (30) days' prior written notice to be given to
the Escrow Agent jointly by the Indemnification Representative and Parent. In
either event, the duties of the Escrow Agent shall terminate thirty (30) days
after the date of such notice (or as of such earlier date as may be mutually
agreeable), and the Escrow Agent shall then deliver the balance of the Escrow
Shares, and all related stock transfer powers then in its possession to a
successor Escrow Agent as shall be appointed by the other parties hereto as
evidenced by a written notice filed with the Escrow Agent.

                           7.1.2 COURT APPOINTMENT. If the parties hereto are
unable to agree upon a successor or shall have failed to appoint a successor
prior to the expiration of thirty (30) days following the date of the notice of
resignation or removal, then the acting Escrow Agent, at the expense of the
Holders and Parent, may petition any court of competent jurisdiction for the
appointment of a successor Escrow Agent or other appropriate relief, and any
such resulting appointment shall be binding upon all of the parties hereto.

                  7.2 SUCCESSORS. Every successor appointed hereunder shall
execute, acknowledge and deliver to its predecessor, and also to the
Indemnification Representative and Parent, an instrument in writing accepting
such appointment hereunder, and thereupon such successor, without any further
act, shall become fully vested with all the duties, responsibilities and
obligations of its predecessor; but such predecessor shall, nevertheless, on the
written request of its successor or any of the parties hereto,

                                      -8-

<PAGE>   9


execute and deliver an instrument or instruments transferring to such successor
all the rights of such predecessor hereunder, and shall duly assign, transfer
and deliver all property, securities and monies held by it pursuant to this
Escrow Agreement to its successor. Should any instrument be required by any
successor for more fully vesting in such successor the duties, responsibilities,
and obligations hereby vested or intended to be vested in the predecessor, any
and all such instruments in writing shall, on the request of any of the other
parties hereto, be executed, acknowledged, and delivered by the predecessor.

                  7.3 NEW ESCROW AGENT. In the event of an appointment of a
successor, the predecessor shall cease to be escrow agent of any funds,
securities or other assets and records it may hold pursuant to this Escrow
Agreement, and the successor shall become such escrow agent.

                  7.4 RELEASE. Upon acknowledgment by any successor Escrow Agent
of the receipt of the then remaining balance of the Escrow Shares, the then
acting Escrow Agent shall be fully released and relieved of all duties,
responsibilities and obligations under this Escrow Agreement that may arise and
accrue thereafter.

                  7.5 SUCCESSORS. Any corporation or association into which the
Escrow Agent in its individual capacity may be merged or converted or with which
it may be consolidated, or any corporation or association resulting from any
merger, conversion or consolidation to which the Escrow Agent in its individual
capacity shall be a party, or any corporation or association to which all or
substantially all the corporate trust business of the Escrow Agent in its
individual capacity may be sold or otherwise transferred, shall be the Escrow
Agent hereunder without further act.

         8.       FEE
                  ---

         The Escrow Agent will be paid by Parent as billed for services and
expenses hereunder in accordance with the fee schedule attached hereto as
EXHIBIT 8, (which fee schedule is subject to change on an annual basis at the
same rate at which the Escrow Agent changes its rates generally for comparable
services provided to its other customers). Without limiting the foregoing,
Parent will reimburse the Escrow Agent for reasonable costs and expenses
incurred in the preparation and administration of this Agreement in the manner
contemplated by this Agreement, all in accordance with the fee schedule attached
hereto as EXHIBIT 8. In the event that the Escrow Agent is made a party to
litigation with respect to the property held hereunder, or brings an action in
interpleader, or in the event that the conditions to this Escrow Agreement are
not promptly fulfilled, or the Escrow Agent is required to render any service
not provided for in this Escrow Agreement and fee schedule, or there is any
assignment of the interests of this Escrow Agreement or any modification hereof,
the Escrow Agent shall be entitled to reasonable compensation from Parent for
such extraordinary services and reimbursement for all fees, costs, liability,
and expenses, including attorneys fees and expenses.

         9.       INDEMNIFICATION REPRESENTATIVE
                  ------------------------------

                  9.1 APPOINTMENT AND AUTHORITY. For purposes of this Escrow
Agreement, the Holders have, by the execution of this Escrow Agreement,
irrevocably consented to the appointment of Manuel Del Arroz as the
Indemnification Representative as representative of the Holders and as the
attorney-in-fact for and on behalf of each Holder, and, subject to the express
limitations set forth below, the taking by the Indemnification Representative of
any and all actions and the making of any decisions required or permitted to be
taken by him under this Escrow Agreement, including but not limited to the
exercise of the power to: (i) authorize delivery to Parent of the Escrow Shares,
or any

                                      -9-

<PAGE>   10


portion thereof, in satisfaction of Claims otherwise in connection with an
Escrow Adjustment, (ii) agree to, negotiate, enter into settlements and
compromises of, and demand arbitration and comply with orders of courts and
awards of arbitrators with respect to such Claims, (iii) resolve any Claims, and
(iv) take all actions necessary in the judgment of the Indemnification
Representative for the accomplishment of the foregoing and all of the other
terms, conditions, and limitations of this Escrow Agreement. Any notice given to
the Indemnification Representative will constitute notice to each and all of the
Holders at the time notice is given to the Indemnification Representative. Any
action taken by, or notice or instruction received from, the Indemnification
Representative will be deemed to be an action by, or notice or instruction from,
each and all of the Holders. Parent and the Escrow Agent will disregard any
notice or instruction received from any Holder other than the Indemnification
Representative with regard to this Escrow Agreement. The Indemnification
Representative shall have unlimited authority and power to act on behalf of each
Holder with respect to this Escrow Agreement and the disposition, settlement, or
other handling of all Claims, notices, rights, or obligations arising under this
Escrow Agreement so long as all Holders are treated in the same manner (in
respect of their proportional interests in the Escrow Shares). Until notified in
writing by the Indemnification Representative that such Indemnification
Representative has resigned or by a majority in interest of the Holders that the
Indemnification Representative has been removed, the Escrow Agent may act upon
the directions, instructions and notices of the Indemnification Representative
named herein or any successor named in a writing signed by a
majority-in-interest of the Holders and filed with the Escrow Agent.

                  9.2 INDEMNIFICATION. The Indemnification Representative shall
not suffer any liability or loss for any act performed or omitted to be
performed by him under this Escrow Agreement in the absence of adjudicated gross
negligence, bad faith or willful misconduct. The Indemnification Representative
may consult with counsel and other experts as may be reasonably necessary to
advise him with respect to his rights and obligations hereunder and shall be
fully protected by any act taken, suffered, permitted, or omitted in good faith
in accordance with the advice of such counsel and experts. The Indemnification
Representative shall not be responsible for the sufficiency or accuracy of the
form, execution, validity, or genuineness of documents or securities now or
hereafter deposited hereunder, or of any endorsement thereof or for any lack of
endorsement thereon, or for any description therein, nor shall he be responsible
or liable in any respect on account of the identity, authority or rights of the
persons executing or delivering or purporting to execute or deliver any such
document, security or endorsement, and the Indemnification Representative shall
be fully protected in relying upon any written notice, demand, certificate or
document which he in good faith believes to be genuine.

                  9.3 DEATH OR DISABILITY; SUCCESSORS. In the event of the death
or permanent disability of the Indemnification Representative, or his
resignation as the Indemnification Representative, a successor Indemnification
Representative shall be elected by a majority vote of the Holders, with each
Holder to be given a vote equal to his proportionate share of the Escrow Shares.
The Holders shall cause to be delivered to Parent and the Escrow Agent prompt
written notice of such election of a successor Indemnification Representative.
Each successor Indemnification Representative shall have all of the power,
authority, rights, and privileges conferred by this Agreement upon the original
Indemnification Representative, and the term, "INDEMNIFICATION REPRESENTATIVE"
as used herein shall be deemed to include any successor Indemnification
Representative.

         10.      TERMINATION; DEFICIENCY CLAIMS
                  ------------------------------

                  This Escrow Agreement and the escrow created hereby shall
terminate following Escrow Agent's delivery, and Parent's release of all
remaining Escrow Shares, and all related stock transfer powers to the Holders
and/or Parent pursuant to Section 2 or 3. In the event that upon the termination
of this Escrow Agreement, the value of the Escrow Shares released to Parent
pursuant to the provisions of this Escrow Agreement is insufficient to pay in
full to Parent the total amount of the Damages and Prevailing Party Awards to
which it is entitled, then, subject to the limitations in Article X of the
Merger Agreement, Parent shall be entitled to pursue its remedies for any such
deficiency under the Merger Agreement; provided, however, that no party hereto
in connection with any such action may contest any Uncontested Claim or any
Contested Claim that has been resolved in accordance with the provisions of this
Escrow Agreement.

         11.      MISCELLANEOUS PROVISIONS
                  ------------------------

                  11.1 PARTIES IN INTEREST. This Escrow Agreement is not

Agreement shall be binding upon and inure to the benefit of and be enforceable

                  11.2 ATTORNEYS' FEES. In the event of any action to enforce
any provision of this Escrow Agreement, or on account of any default under or
breach of this Escrow Agreement with regard to Parent, Calogic and/or the
Holders, the substantially prevailing party in such action shall be entitled to
recover, in addition to all other relief, from the other party all attorneys'
fees incurred by the substantially prevailing party in connection with such
action (including, but not limited to, any appeal thereof).

                  11.3 ENTIRE AGREEMENT. This Escrow Agreement constitutes the
final and entire agreement among the parties with respect to the subject matter
hereof and supersedes all prior arrangements or understandings.

                  11.4 NOTICES. All notices, requests, demands or other
communications which are required or may be given pursuant to the terms of this
Agreement shall be in writing and shall be deemed to have been duly given: (i)

                      AMENDED AND RESTATED HOLDER AGREEMENT


         This Amended and Restated Holder Agreement (this "AGREEMENT") is made
and entered into as of November 23, 1999 by and among SIPEX Corporation, a
Massachusetts corporation ("PARENT"); Calogic, a California corporation
("CALOGIC"); and Manuel Del Arroz, a security holder of Calogic (the "HOLDER").

         A. CAT Acquisition Corporation I, a Delaware corporation and wholly
owned subsidiary of Parent ("MERGER SUB"), Calogic, and the Holder have entered
into an Agreement and Plan of Reorganization dated as of October 21, 1999 (as
the same from time to time may be amended, supplemented, restated or otherwise
modified, the "MERGER AGREEMENT") setting forth certain terms and conditions
pursuant to which Merger Sub is being merged into Calogic (the "MERGER").

         B. Parent, Calogic and the Holder are parties to a Holder Agreement
dated as of October 21, 1999 (the "Original Agreement"), pursuant to which the
Parent, Calogic and the Holder have agreed to take certain actions in connection
with the Merger.

         C. The parties desire to amend and restate the Original Agreement as
set forth below and the parties are willing to so amend and restate the Original
Agreement, but only on the terms and subject to the conditions set forth below.

         D. Unless otherwise indicated herein, all terms used herein without
definition shall have the same meaning as set forth in the Merger Agreement.

         NOW THEREFORE, for and in consideration of the foregoing and the mutual
covenants and agreements contained in the Merger Agreement and in this
Agreement, pursuant to Section 5 of the Original Agreement the parties do hereby
amend the Original Agreement so that such agreement is hereby restated in its
entirety to read as follows:





         1.       ACTIONS TO BE TAKEN WITH RESPECT TO COMPENSATION ARRANGEMENTS.

                  (a) Calogic and the Holder will each use its commercially
reasonable efforts, will cooperate fully and will take all commercially
reasonable actions as are necessary to achieve the results described on
Schedule1.1 hereto (the "Compensation Actions"). The parties hereby agree and
acknowledges that no efforts or actions should be taken with respect to the
Compensation Actions that would prevent the Merger and other transactions
contemplated by the Merger Agreement from being accounted for as a "pooling of
interests" in accordance with United States generally accepted accounting
principles which will be acceptable to the Commission.

                  (b) Calogic and Holder hereby agree that no efforts or actions
will be undertaken with respect to the Compensation Actions without consultation
with Parent and KPMG LLP, its



<PAGE>   2


independent accountants. Calogic and Holder also agree that, without the prior
written consent of Parent, which shall not be unreasonably withheld, (i) no
monies shall be paid with respect to the Compensation Actions; (ii) no offers
shall be made with respect to the Compensation Actions; and (iii) no agreements
shall be entered into with the persons identified on Schedule1.1 hereto.

                  (c) In the event that the Compensation Actions are not
completed prior to the Closing, Holder hereby agrees to defend, indemnify and
hold Parent harmless from and against, and to reimburse Parent with respect to,
any and all Losses of every nature whatsoever incurred by Parent (which will be
deemed to include any of the foregoing incurred by the Surviving Corporation) by
reason of or arising out of or in connection with (i) the matters set forth on
Schedule1.2 and (ii) the failure, partial or total, of Calogic or the Holder to
perform any agreement or covenant required by this Agreement to be performed by
it or him other than any breach or related claim taken or not taken at the
written direction of or after consultation with and written concurrence of
Parent. The foregoing obligation to indemnify Parent is in addition to the
obligation to indemnify Parent pursuant to Article X of the Merger Agreement and
such obligation is not subject to the limitations of such Article X. Holder will
have the right to defend, contest, negotiate or settle any such claim or demand
relating to the Compensation Actions through counsel of his own selection,
reasonably satisfactory to Parent, and solely at the Holder's own cost and
expense. Notwithstanding the preceding sentence, Holder will not settle,
compromise, or offer to settle or compromise any such claim or demand without
the prior written consent of Parent, which consent will not be unreasonably
withheld. Without limiting Parent's rights to object for other reasons, Parent
may object to a settlement or compromise which includes any provision which in
its reasonable judgment may have an adverse impact on or establish an adverse
precedent for the Business Condition of Parent or any of its Subsidiaries.
Notwithstanding anything to the contrary in this Agreement, Parent may pay or
settle, any such claim at any time if it waives its right to indemnification
under this Agreement, the Merger Agreement and the Escrow Agreement.

         2.       GENERAL PROVISIONS REGARDING INDEMNIFICATION AND RELEASES

                  (a) For purposes of indemnification under this Agreement or
the Merger Agreement, Calogic and Holder hereby acknowledge and agree that the
provisions of Section 12.14 of the Merger Agreement shall be inapplicable with
respect to the claims by Parent arising out of or in connection with the matters
set forth on Schedule2.1 hereto or any agreements related thereto.

                  (b) The limitation on the obligation of Holder for Losses will
be a dollar amount equal to the aggregate number of Parent Merger Shares
received by Holder pursuant to the Merger Agreement multiplied by the Parent
Average Closing Price.

                  (c) Any agreement obtained by Calogic or Holder in respect of
the matters set forth on Schedule 2.1 shall contain a release substantially in
the form of Exhibit A hereto.

         3.       ARBITRATION.

                  (a) ARBITRATION RULES. Any dispute between the Holder and
Parent under this Agreement shall be submitted to final and binding arbitration
before a single arbitrator in Boston, Massachusetts in accordance with the
commercial arbitration rules of the American Arbitration Association.

                                      -2-

<PAGE>   3


                  (b) BINDING EFFECT. The final decision of the arbitrator shall
be furnished in writing to the Holder and Parent and will constitute a
conclusive determination of the issue in question, binding upon the Holder and
Parent. The arbitrator shall have the authority to grant any equitable and legal
remedies that would be available in any judicial proceeding instituted to
resolve a dispute. Any judgment upon the award rendered by the arbitrator may be
entered in any court having jurisdiction over the subject matter thereof.

                  (c) COMPENSATION OF ARBITRATOR. The arbitrator will be
compensated for his or her services, as provided below in Section 3(d), in
accordance with the commercial arbitration rules of the American Arbitration
Association.

                  (d) PAYMENT OF COSTS. The substantially prevailing party in
any arbitration shall be entitled to an award of attorneys' fees and costs, and
all costs of arbitration, including those provided for above, will be paid by
the losing party, subject in each case to a determination by the arbitrator as
to which party is the substantially prevailing party and the amount of such fees
and costs to be allocated to such party and subject to the terms of Section
3(c).

         4.       MISCELLANEOUS PROVISIONS

                  (a) PARTIES IN INTEREST. This Agreement is not intended, nor
shall it be construed, to confer any enforceable rights on any Person not a
party hereto. All of the terms and provisions of this Agreement shall be binding
upon and inure to the benefit of and be enforceable by the respective successors
and assigns of the parties hereto.

                  (b) ATTORNEYS' FEES. In the event of any action to enforce any
provision of this Escrow Agreement, or on account of any default under or breach
of this Agreement, the substantially prevailing party in such action shall be
entitled to recover, in addition to all other relief, from the other party all
attorneys' fees incurred by the substantially prevailing party in connection
with such action (including, but not limited to, any appeal thereof).

                  (c) ENTIRE AGREEMENT. This Agreement constitutes the final and
entire agreement among the parties with respect to the subject matter hereof and
supersedes all prior arrangements or understandings, including, without
limitation, the Holder Agreement among the parties dated October 21, 1999.

                  (d) CHANGES. The terms of this Agreement may not be modified
or amended, or any provisions hereof waived, temporarily or permanently, except
pursuant to the written agreement of Parent and the Holder.

                  (e) SEVERABILITY. If any term or provision of this Agreement
or the application thereof as to any Person or circumstance shall to any extent
be invalid or unenforceable, the remaining terms and provisions of this
Agreement or the application of such term or provision to persons or
circumstances other than those as to which it is held invalid or unenforceable
shall not be affected thereby and each term and provision of this Agreement
shall be valid and enforceable to the fullest extent permitted by law.

                                      -3-

                  (f) COUNTERPARTS. This Agreement may be executed in two or
more partially or fully executed counterparts, each of which shall be deemed an
original and shall bind the signatory, but all of which together shall
constitute but one and the same instrument.

                  (g) HEADINGS. The headings of the various sections of this
Agreement have been inserted for convenience of reference only and shall not be
deemed to be a part of this Agreement.

                  (h) GOVERNING LAW. This Agreement shall be construed and
controlled by the laws of the Commonwealth of Massachusetts without regard to
the principles of conflicts of laws. Calogic and the Holders consent to
jurisdiction and venue in the state and federal courts in Boston, Massachusetts.
