(1)  597,882 of the shares of Common Stock of Carleton Corporation ("Carleton")
     covered by this statement are subject to an option to purchase shares on

     the shares of Common Stock of Carleton covered by this statement are
     subject to Voting and Proxy Agreements ("Voting and Proxy Agreements")
     described in Item 4 of this statement. Nothing herein shall be deemed to be
     an admission by Oracle Corporation ("Oracle") as to the beneficial

     the Voting and Proxy Agreements, and Oracle hereby disclaims beneficial
     ownership of all such shares of Carleton so subject.

         address of Carleton's principal executive office is 10729 Bren Road
         East, Minnetonka, MN 55343.

Item 2   Identity and Background.

         This statement is filed by Oracle Corporation ("Oracle"), a corporation

         The name, business address and present principal occupation or
         employment of each executive officer and director of Oracle are set
         forth in Schedule I to this statement which is incorporated herein by
         reference.

         To the knowledge of the reporting person, Oracle and its respective
         officers and directors have not, during the last five years, been
         convicted in a criminal proceeding (excluding traffic violations and
         similar misdemeanors) or been a party to a civil proceeding of a
         judicial or administrative body of competent jurisdiction and as a
         result of such proceeding been or become subject to a judgment, decree
         or final order enjoining future violations of, or prohibiting or
         mandating activities subject to, federal or state securities laws or
         finding any violation with respect to such laws.

Item 3.  Source and Amount of Funds or Other Consideration.

         Any shares purchased pursuant to the exercise of an option to purchase
         stock upon certain contingencies (the "Option") described in Item 4 of
         this statement would be made with funds from Oracle's working capital.
         The aggregate purchase price of such shares is $1,464,811, or $2.45 per
         share, subject to adjustment as provided in Section 6.10 of the
         Agreement of Merger dated November 8, 1999 (the "Merger Agreement"),
         set forth as Exhibit 1.

Item 4.  Purpose of Transaction.

         This statement relates to the granting of the Option set forth in
         Section 6.10 of the Merger Agreement among Carleton, Oracle and DM
         Acquisition Corp. ("Buyer Subsidiary"), a wholly owned subsidiary of
         Oracle, and to the execution of certain Voting and Proxy Agreements
         between Oracle and each of the following Carleton stockholders: Robert
         D. Gordon, Nicholas J. Covatta, Jr., Michael Dexter-Smith, Robert W.
         Fischer, George E. Hubman, Arch J. McGill, David Batt, Alexander F.
         Collier, David M. Haggerty and Travis M. Richardson (the "Voting and
         Proxy Agreements").

         The Option and the Voting and Proxy Agreements are intended as an
         inducement to Oracle to enter into and proceed with the Merger
         Agreement between Carleton, Oracle and Buyer Subsidiary, and the Plan
         of Merger attached to the Merger Agreement as Exhibit A.

                                       4
<PAGE>

         Pursuant to both the Merger Agreement and Plan of Merger and subject to
         the conditions set forth therein, Buyer Subsidiary will merge with and
         into Carleton (the "Merger"), and each issued and outstanding share of
         Common Stock of Carleton will be converted into the right to receive
         $2.45 in cash, without interest (the "Merger Consideration").
         Consummation of the merger is subject to certain conditions, including
         (i) receipt of the approval of the Merger Agreement by the holders of a
         majority of the outstanding shares of Carleton Common Stock; (ii)
         notice of intent to dissent under Section 302A.473 of the Minnesota
         Business Corporation Act shall not have been filed with respect to more
         than 10% of the outstanding Shares as of the time stated in the Merger
         Agreement; (iii) certain specific actions contemplated by the Merger
         Agreement with respect to third parties shall have been taken; (iv) no
         change in the Chief Executive Officer, Executive Vice President Sales,
         Vice President Marketing, Vice President Engineering or Vice President
         Professional Services of the Company shall have occurred and no less
         than 80% of certain designated employees shall have indicated to
         Oracle, in a reasonably satisfactory form, their intention to continue
         employment with the Company; (v) certain specified warrants shall have
         been exercised and/or canceled in accordance with the terms of the
         Merger Agreement; (vi) certain individuals as specified in the Merger
         Agreement shall have entered into employment and non-competition
         agreements in a reasonably satisfactory form; and (vii) satisfaction of
         certain other conditions.

         Pursuant to the Option, Carleton granted Oracle the right to purchase
         at an exercise price of the Merger Consideration, subject to adjustment
         as provided in the Merger Agreement, up to 597,882 shares of Carleton
         Common Stock. The Option is not exercisable until and unless certain
         events specified therein including, but not limited to: (a) the
         termination of the Merger Agreement by the Company's Board of Directors
         in order to enter into an agreement with respect to a Superior
         Proposal, as such term is defined therein; (b) the Company enters into
         a Third Party Transaction, as such term is defined therein, announced
         within 12 months after (i) a withdrawal of the Company Board of
         Directors recommendation of the Merger Agreement, (ii) a termination by
         either party after March 31, 2000, (iii) the Merger is voted down by
         the Company's stockholders and (iv) certain other circumstances; (c)
         any person other than Oracle or its affiliates commences a tender offer
         within the meaning of Rule 14d-2 under the Securities and Exchange Act
         of 1934 for 15% or more of the Company's outstanding shares; and (d)
         certain other circumstances.

         Pursuant to the Voting and Proxy Agreements, each of the persons noted
         above has agreed to vote all of such person's Carleton shares that such
         person has the power to vote in favor of approval of the Merger
         Agreement and against any acquisition proposal or transaction with a
         party other than Oracle, and has executed an irrevocable proxy granting
         Oracle the right to vote, or to execute and deliver stockholder written
         consents, in respect of such person's shares in accordance with such
         Voting and Proxy Agreement.

         The purpose of the transactions described in this Item 4 is to
         facilitate approval and consummation of the Merger. Other than in
         connection with the Merger described above, the reporting person has no
         plans or proposals which relate to or would result in any of the
         matters listed in paragraphs (a) through (j) of Item 4 of Schedule 13D.

                                       5
<PAGE>

         Copies of the Merger Agreement, Plan of Merger and Form of the Voting
         and Proxy Agreement are included as Exhibits to this statement and are
         incorporated herein by reference. The foregoing description of such
         agreements is qualified in its entirety by reference to such Exhibits.

Item 5.  Interest in Securities of the Issuer.

         (a)  Although the Option does not allow Oracle to purchase any shares
              pursuant thereto unless and until the conditions to exercise
              occur, assuming for purposes of this Item 5 that such conditions
              are satisfied and Oracle is entitled to purchase shares pursuant
              to the Option, Oracle will be entitled to purchase 597,882 shares
              of Common Stock of Carleton, or approximately 15.1%, after giving
              effect to the exercise of the Option. Notwithstanding this, if an
              exercise of the Option would otherwise produce a gain in excess of
              (i) $520,000 minus (ii) any Termination Fee payable, as such term
              is defined in the Merger Agreement, then the exercise of the
              Option would be effective only as to the number of shares which
              produce a gain in such amount. Until such conditions are
              satisfied, Oracle does not have the right to acquire the shares
              and does not posses voting or dispositive power under the Option.
              If such conditions are satisfied and Oracle exercises the Option,
              it will have sole voting and dispositive power with respect to
              such shares. As a result of the Voting and Proxy Agreements,
              Oracle may be deemed to be the beneficial owner of 89,745 shares
              of Common Stock of Carleton, or approximately 2.7%, covered by
              such Agreements. Such 687,627 shares (including those covered by
              the Option and those covered by the Voting and Proxy Agreements)
              would represent approximately 17.4% of the shares of Carleton
              (based on the number of shares of Carleton Common Stock
              outstanding on November 3, 1999 and calculated pursuant to Rule
              13d-3(d)(1), as represented to Oracle by Carleton). Nothing
              herein, however, shall be deemed to be an admission by Oracle that
              it is the beneficial owner of any of the shares covered by the
              Option or the Voting and Proxy Agreements, and Oracle hereby
              disclaims beneficial ownership of all shares covered by the Option
              and the Voting and Proxy Agreements.

         (b)  Oracle will have the sole power to vote and dispose of the 597,882
              shares of Carleton Common Stock for which it may be deemed
              beneficial owner should it become entitled and elect to exercise
              the Option. Oracle has shared power to direct the voting of the
              89,745 shares subject to the Voting and Proxy Agreements, and no
              power to dispose of such shares. No other person is known to have
              or share the right to receive or the power to direct the receipt
              of dividends from, or the proceeds from the sale of, such
              securities.

         (c)  To the knowledge of the reporting persons, the only transactions
              in the Common Stock of Carleton by any person named in this Item
              5(a) during the past 60 days are the Option and Voting and Proxy
              Agreements reported in Item 3 above.

         (d)  No other person (other than the Carleton stockholders who have
              signed a Voting and Proxy Agreement in the case of the shares
              covered by such stockholder's Voting and Proxy Agreement) is known
              to have the right to receive or the power to direct the receipt of
              dividends from, or the proceeds of the sale of, the subject
              securities.

design furnished by the Company or a Subsidiary, and not software design, and
any right assertable by such consultants would not materially interfere with the
Company's provision, marketing or use, or presently proposed provision,
marketing or use, of such code.

         (g) The Company and each of its Subsidiaries has taken all commercially
reasonable steps to protect and preserve the confidentiality of all Confidential
Information. Except as set forth on

                                       13
<PAGE>

Schedule 2.21(g), all use, disclosure or appropriation of Confidential
Information by or to a third party has been pursuant to the terms of a written
confidentiality or nondisclosure agreement between the Company or any Subsidiary
and such third party. Schedule 2.21(g) lists all such agreements currently in
effect.

         (h) Schedule 2.21(h) lists (including names, addresses, contact names,
telephone numbers and termination date and next renewal date) all Contracts or
other arrangements currently in effect pursuant to which the Company or any
Subsidiary is obligated to provide installation, maintenance or other support
services (collectively, the "Support Agreements"). Except for any nonstandard
maintenance agreements specified as such in Schedule 2.21(h), all of the Support
Agreements are in all material respects in the form of the license agreement
identified as the standard maintenance agreement set forth in Schedule 2.21(h).
The versions of the products currently supported by the Company are set forth in
Schedule 2.21(h).

         (i) There are no material defects in the Company's products, and there
are no material errors in any documentation, specifications, manuals, user
guides, promotional material, internal notes and memos, technical documentation,
drawings, flow charts, diagrams, source language statements, demo disks,
benchmark test results, and other written materials related to, associated with
or used or produced in the development of the Company's or its Subsidiaries'
products, which defects or errors have or are reasonably like to have,
individually or in the aggregate, a Material Adverse Effect. To the Company's
knowledge, the current versions of Pure-View, including, without limitation, any
time-and-date-related codes, data entry features and internal subroutines
thereof, (a) automatically accommodate the change in the date from December 31,
1999 to January 1, 2000 without negatively affecting Pure-View's performance;
and (b) accurately accept, reflect and calculate all dates that are relevant to
Pure-View's performance, when used with products that properly exchange date
data with Pure-View.

         (j) Schedule 2.21(j) lists, as of the date hereof, all written
agreements or other arrangements under which the Company or any Subsidiary has
provided or agreed to provide source code of Pure-View or any other Company
Intellectual Property to any third Person, whether pursuant to escrow
arrangements or otherwise.

         (k) The Company has made available to the Buyer copies of the Company's
standard forms of end-user license. Schedule 2.21(k) sets forth all end-user
licenses currently in effect for products currently marketed by the Company or a
Subsidiary and any component of any such product.

         (l) No government funding or university or college facilities were used
in the development of Pure-View and Pure-View was not developed pursuant to any
contract or other agreement with any person or entity except pursuant to
contracts or agreements listed in Schedule 2.21(l).

         (m) The Company has no customer warranty obligations currently in
effect other than as set forth in end-user agreements listed in Schedule
2.21(k). The Company categorizes software problems reported by its or its
Subsidiaries' customers into priority 1 items (software is inoperative;
inability to use has a critical impact on customer's operations), priority 2
items (software is partially inoperative and inoperative portion is considered
severely restrictive), priority 3 items (software is usable with some limited
functions; error condition is not critical to continued operations) and priority
4 items (software is usable; error condition is cosmetic or trivial). Schedule
2.21(m) lists all

                                       14
<PAGE>

currently pending priority 1, 2 and 3 items related to products currently or
previously marketed by the Company or a Subsidiary and the nature thereof that
are pending or were made within the past twelve months. Except as set forth in
Schedule 2.21(m), to the knowledge of the Company, the Company has not made any
material oral or written representations or warranties with respect to its
products or services.

         2.22 Capital Expenditures. Schedule 2.22 sets forth, by nature and
amount, all budgeted capital expenditures of the Company and its Subsidiaries
for which commitments have been or are budgeted to be made, or for which
payments or current liabilities have been made or incurred or are budgeted to be
made or incurred, after the Last Fiscal Year-End in excess of $5,000.

         2.23 Environmental Matters. There are no Hazardous Materials used or
present at any location used by the Company or a Subsidiary or any predecessor
of either in the conduct of the Business, except for any Hazardous Materials
constituting normal office supplies. To the knowledge of the Company, no
location currently or previously used by the Company or a Subsidiary or any
predecessor of either is contaminated by any Hazardous Material or was
previously used for any purpose other than office space. There are no
environmental materials or conditions, including on-site or off-site disposal or
releases of Hazardous Materials that could reasonably be expected to have a
Material Adverse Effect. To the knowledge of the Company, no event has occurred
and no activity has been or is being conducted by the Company, a Subsidiary or
any other Person which has resulted or could reasonably result in contamination
of any location currently or previously used by the Company or a Subsidiary or
any predecessor of either by any Hazardous Material. Neither the Company, any
Subsidiary nor any predecessor of either has received any written communication
from any Governmental Entity alleging that the Company, Subsidiary or
predecessor or any premises currently or previously occupied by any of such
Persons is contaminated by any Hazardous Materials or in violation of any
Environmental Requirement. To the knowledge of the Company, no Government Agency
has commenced any investigation or proceeding with respect to the contamination
of any location currently or previously used by the Company or a Subsidiary or
any predecessor of either by any Hazardous Material.

         2.24 Illegal Payments. To the best knowledge the Company, none of the
Company, any Subsidiary or any director, officer, employee, or agent of the
Company or any Subsidiary has, directly or indirectly, paid or delivered any
fee, commission, or other sum of money or item of property however characterized
to any broker, finder, agent, government official, or other person, in the
United States or any other country, in any manner related to the business or
operations of the Company or any Subsidiary, which the Company, any Subsidiary
or any such director, officer, employee, or agent knows or has reason to believe
to have been illegal under any law.

         2.25 SEC Information. Except as set forth in Schedule 2.25, as of their
respective filing dates (except as thereafter amended) all documents that the
Company has filed with the SEC (the "Company SEC Documents") have complied in
all material respects with the applicable requirements of the Act or the
Exchange Act, and none of the Company SEC Documents has contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements made therein, in
light of the circumstances under which they were made, not misleading except to
the extent corrected by a subsequently filed Company SEC Document filed prior to
the date hereof.

         2.26  Board of Directors Approval; Fairness Opinion.

         (a)  The Board of Directors of the Company has unanimously approved
this Agreement and the Plan of Merger and unanimously recommended this Agreement
and the Plan of Merger to the Company's stockholders. Such approval and
recommendation have not been modified or withdrawn and are in full force and
effect on the date hereof. The Amended and Restated Rights Agreement dated as of
September 4, 1996 has been duly amended to exempt the Merger and the other
transactions contemplated by this Agreement from the operation of such Agreement
and, accordingly, Section 13 of such Agreement does not apply to the Merger. All
Rights will expire automatically upon the consummation of the Merger. The
Company's financial adviser, Dougherty Summit Securities, LLC, has rendered its
opinion to the Board of Directors of the Company that the consideration to be
received in the Merger is fair to the Company's stockholders from a financial
point of view. Prior to the Company's entry into this Agreement, each of the
Company's officers and directors has granted the Buyer an irrevocable proxy to
vote all Shares beneficially owned by such officer or director in favor of the
Merger.

         (b)  The transactions contemplated by this Agreement (i) are not
subject to the "fair price," "moratorium," "control share acquisition" or other
similar statute (a "Takeover Statute") of any jurisdiction other than the State
of Minnesota. None of the transactions contemplated by this Agreement (including
without limitation the proxies referred to in Section 2.26(a)) involve a
"control share acquisition" within the meaning of Section 302A.671 of the
Minnesota Business Corporation Act. A committee of the Board of Directors of the
Company formed pursuant to Section 302A.673(d) of such Act has unanimously
approved the transactions contemplated by this Agreement, and the restriction of
Section 306A.673(a) of such Act accordingly does not apply. There are no other
Takeover Statutes of the State of Minnesota applicable to the Company or any
Subsidiary.

         2.27 Representations. No representation or warranty by the Company in
this Agreement (including without limitation the Schedules and Exhibits attached
hereto), or in any document furnished by the Company at the Closing pursuant
hereto contains any untrue statement of a material fact or omits to state a fact
necessary to make the statements contained in such representation or warranty
not misleading.

obligation of the Buyer and Buyer Subsidiary, enforceable in accordance with its

general application affecting the enforcement of creditors' rights. The

relating to the Buyer or Subsidiary except those listed on Schedule 3.2, (y) do

acceleration or right of acceleration of any obligations under, any Contract to
which the Buyer or Buyer Subsidiary is a party, where, in each case, the absence
of such Third-Party Action or such violation, conflict, default or acceleration

written offer or proposal made by a third party which is reasonably likely to
lead to a Superior Proposal, provide non-public information to or have
discussions or negotiations with such third party, if and only to the extent
that the Board of Directors has determined in good faith, after receiving the

stockholders under applicable law. The Company will immediately communicate to
the Buyer the receipt of any third party solicitation, proposal or bona fide
inquiry that the Company, any Subsidiary or any representative of the Company or
any Subsidiary may receive in respect of any such transaction, or of any request
for such information, including in each case a copy thereof and all other
particulars thereof, and keep the Buyer fully apprised of all developments
therein on a current basis, and consider in good faith any counterproposals
which the Buyer, in its sole discretion, elects to make.

"Group" shall have the meanings stated in Regulation 13D-G under the Securities
Exchange Act of 1934, as amended (the "Exchange Act").

                                       22

         (c)  The Company will take all action necessary in accordance with
applicable law and its articles of incorporation and by-laws to convene a
meeting of its stockholders as promptly as practicable to consider and vote upon
the Merger and to secure the Stockholder Approval, including without limitation
the preparation of a proxy statement (the "Proxy Statement," which term shall
include all amendments and supplement thereto). The Proxy Statement shall comply
as to form in all material respects with the applicable requirements of the
Exchange Act and the rules and regulations promulgated thereunder, and shall
not, at the time of (i) first mailing thereof or (ii) such stockholders'
meeting, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except that the Company shall not be responsible for information
supplied by the Buyer or any affiliates or representatives of the Buyer for
inclusion in the Proxy Statement. The Company (i) shall promptly prepare and
file with the SEC, use all reasonable efforts to have cleared by the SEC and
thereafter mail to its stockholders as promptly as practicable the Proxy
Statement and all other proxy materials for such meeting, (ii) shall notify the
Buyer of the receipt of any comments of the SEC with respect to the Proxy
Statement and of any requests by the SEC for any amendment or supplement thereto
or for additional information and shall promptly provide the Buyer copies of all
correspondence between the Company or any representative of the Company and the
SEC and (iii) shall give the Buyer and its counsel the opportunity to review the
Proxy Statement prior to its being filed with the SEC and shall give the Buyer
and its counsel the opportunity to review all amendments and supplements to the
Proxy Statement and all responses to requests for additional information and
replies to comments prior to their being filed with, or sent to, the SEC.

         (d)  The Board of Directors of the Company shall recommend and declare
advisable to its stockholders such approval and the Company shall take all
lawful action to solicit, and use all best efforts to obtain, approval of its
stockholders, and neither the Board of Directors of the Company nor any
committee of such Board of Directors shall (i) withdraw or modify the approval
or recommendation by such Board of Directors or such committee of the Merger,
(ii) approve or recommend any Acquisition Proposal other than the Merger, or
(iii) cause the Company to enter into any letter of intent, agreement in
principle, acquisition agreement or other similar agreement with respect to any
Acquisition Proposal other than the Merger. Notwithstanding the foregoing, the
Board of Directors of the Company may, prior to the Stockholder Approval,
withdraw or modify its approval or recommendation of the Merger, approve or
recommend a Superior Proposal or terminate this Agreement in order to
simultaneously enter into a binding agreement with respect to a Third-Party
Transaction that constitutes a Superior Proposal, but in each case subject to
its compliance with Section 6.3(b) or (c), as applicable, if and only to the
extent that both (i) the Buyer has been given at least five days written notice
of the Company's intent to do so and (ii) the Board of Directors of the Company
has determined in good faith, after receiving the advice of its outside counsel,
that such action is necessary in order for the Board of Directors to comply with
its fiduciary duties to stockholders under applicable law. A "Superior Proposal"
means any bona fide written Acquisition Proposal, the terms of which the Board
of Directors of the Company determines in its good faith judgment, based on the
advice of its financial advisor, to be more favorable to the Company's
stockholders than the Merger and to be already financed or readily financeable.

         (e)  Nothing in this Section 6.6 shall prohibit the Company from taking
and disclosing to its stockholders a position as contemplated by SEC Rule
14e-2(a), provided that neither the Company

                                       23
<PAGE>

nor its Board of Directors nor any committee of its Board of Directors shall
approve or recommend any Third-Party Proposal except as permitted by
Section 6.6(d).

         6.7  Interim Financial Information. The Company will supply to the
Buyer unaudited consolidated monthly financial statements within 30 business
days of the end of each month ending between the date of the Interim Balance
Sheet and the Closing or any earlier termination of this Agreement in accordance
with its terms, prepared on a basis consistent with the unaudited consolidated
financial statements for the preceding months. For purposes of these statements,
employee bonuses and similar expenses may be accrued based on actual results for
the year to date and budgeted results for the balance of the year.

         6.8  Interim Conduct of Business. From the date of this Agreement until
the Closing or any earlier termination of this Agreement in accordance with its
terms, unless approved by the Buyer in writing, the Company will operate its
business consistently with past practice and in the ordinary course of business,
and will not:

                  (a) merge or consolidate with or agree to merge or consolidate
         with, or sell or agree to sell all or substantially all of its Property
         to, or purchase or agree to purchase all or substantially all of the
         Property of, or otherwise acquire, any other Person or a division
         thereof, except as provided in this Agreement;

                  (b) amend its articles of incorporation or by-laws;

                  (c) make any changes in its accounting methods, principles or
         practices, except as required by GAAP;

                  (d) sell, consume or otherwise dispose of any Property, except
         in the ordinary course of business consistent with past practices;

                  (e) authorize for issuance, issue, sell or deliver any
         additional shares of its capital stock of any class or any securities
         or obligations convertible into shares of its capital stock or issue or
         grant any option, warrant or other right to purchase any shares of its
         capital stock of any class, other than, in each case, the issuance of
         Common Stock pursuant to the exercise of the options and warrants (but
         not the Rights) listed in Section 2.1(a);

                  (f) declare any dividend on, make any distribution with
         respect to, or redeem or repurchase, its capital stock except under
         existing repurchase agreements or obligations as set forth in
         Schedule 2.1;

                  (g) modify, amend or terminate any Benefit Plans, except as
         required under Legal Requirements or any Disclosable Contract; or

                  (h) authorize or enter into an agreement to do any of the
         foregoing.

         6.9 Section 338 Election; Tax Status. The parties agree that the Buyer
may make an election under Section 338(a) of the Code with respect to the
Merger. Each party has reviewed the income and other Tax aspects of the
structure of the Merger with its own professional advisers, and

                                       24
<PAGE>

no party or representative of a party shall have any obligation or
responsibility to any other party with respect thereto.

         6.10   Option to Purchase.

         (a) The Company hereby irrevocably grants the Buyer the right (the
"Option"), at the Buyer's option, to purchase from the Company up to 597,882
(subject to adjustment as provided in this Section 6.10) Shares in the aggregate
at the exercise price of $2.45 per share, subject to adjustment as provided in
this Section 6.10 (as so adjusted, the "Exercise Price"), as specified by the
Buyer in its notice or notices of exercise from time to time, but only in
connection with or after a Triggering Event. A "Triggering Event" means the
first to occur of the following events:

                  (i) the Company terminates this Agreement pursuant to Section
         6.6(d), or

                  (ii) the Board of Directors of the Company withdraws or
         modifies its approval or recommendation of the Merger or approves or
         recommends a Superior Proposal pursuant to Section 6.6(d), or the
         Merger is voted down by the Company's stockholders, or this Agreement
         is terminated by any party prior to the Effective Time after the date
         specified in Section 6.3(a), or if this Agreement is terminated by the
         Buyer due to a material breach hereof by the Company, and in any such
         case a Third-Party Transaction is announced within 12 months after such
         withdrawal, modification, approval, recommendation, vote or termination
         which is thereafter consummated (or is consummated within such 12-month
         period, irrespective of any announcement). Such consummation shall
         constitute the Triggering Event within the scope of this Section
         6.10(a)(ii).

                  (iii) any Person other than an Affiliate of the Buyer
         commences a tender offer (within the meaning of SEC Rule 14d-2) for 15%
         of more of the Company's outstanding Shares.

         (b) The Company will give the Buyer notice of any proposed Triggering
Event under Section 6.10(a)(ii) or (iii) to which it is a party at least 20 days
prior to the proposed consummation thereof, and will give the Buyer notice of
any other such Triggering Event immediately upon receiving knowledge thereof.
The Option may be exercised, at any time and from time to time, commencing
immediately prior to the Triggering Event and continuing thereafter until 5:00
p.m., California time, on the 5th anniversary of the date of this Agreement, if
a business day, or on the next succeeding business day if it is not. To exercise
the Option, the Buyer shall deliver written notice to the Company at its address
listed in Section 7.4 specifying the number of Shares as to which the Option is
being exercised, accompanied by the Buyer's check or wire transfer in payment of
the aggregate Exercise Price. Alternatively, the Buyer may pay the Exercise
Price by surrender of this Option with respect to a number of shares whose
aggregate Spread Value equals the aggregate Exercise Price. "Spread Value" means
(i) the excess, if any, of the market value of a Share over the Exercise Price
times (ii) the number of Shares so to be surrendered. For this purpose, "market
value" shall mean the average closing price of Shares for the three most recent
trading days ending with the second trading day prior to any such cashless
exercise, if Shares are then traded on a national securities exchange or the
Nasdaq National Market, and will mean the per-Share value of the transaction
associated with the Triggering Event in all other cases.

                                       25
<PAGE>

         (c) Upon any exercise of the Option as set forth above, the Buyer shall
immediately be the record owner of all Shares subject to such exercise for all
purposes, without any other action being necessary. Within three trading days
after each exercise of the Option, the Company shall deliver certificates for
the Shares so purchased to the Buyer, but the delivery of such certificates
shall not be required in order for the Buyer to exercise any rights as a holder
of the Shares to be represented thereby. Until its exercise, the Option does not
confer on the Buyer any rights of a stockholder of the Company.

         (d) The Company need not issue any fractional shares in connection with
any exercise of the Option. Instead, the Buyer may purchase a whole Share from
the Company at the Exercise Price.

         (e) During the term of the Option, the Company shall reserve sufficient
authorized but unissued shares of Common Stock or other securities for the full
exercise of the rights represented by the Option. To the extent required for the
lawful exercise of the Option, the Company will promptly make all filings with
Governmental Agencies, including without limitation a premerger notification
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
requested by the Buyer in connection with an intended exercise of the option.

         (f) The Exercise Price and the number of Shares that the Company must
issue upon exercise of the Option are subject to adjustment from time to time as
follows:

                  (1) If the Company at any time or from time to time after the
         date hereof: (1) declares or pays, without consideration, any dividend
         on Shares payable in Shares; (2) creates any right to acquire Shares
         for no consideration; or (3) subdivides the outstanding Shares (by
         stock split, reclassification or otherwise), the Company shall increase
         the number of Shares that the Buyer may purchase upon exercising the
         Option and decrease the Exercise Price in proportion to the increase in
         the number of outstanding Shares that results from any such action.

                  (2) If the Company combines or consolidates the outstanding
         Shares, by reclassification or otherwise, into a lesser number of
         Shares, the Company shall decrease the number of Shares that the Buyer
         may purchase upon exercising the Option and increase the Exercise Price
         in proportion to the decrease in the number of outstanding Shares that
         results from any such combination or consolidation.

                  (3) If Shares change into shares of any other class or classes
         of security or into any other Property for any reason other than a
         subdivision or combination of Shares provided for in Section 6.10(f)(1)
         or (2), including without limitation any reorganization,
         reclassification, merger or consolidation and any sale of substantially
         all of the Company's properties and assets, the Company shall make
         lawful provision for giving the Buyer the right, by exercising the
         Option, to purchase the kind and amount of securities or other Property
         receivable upon any such change by the owner of the number of Shares
         subject to this Option immediately before the change.

                  (4) If the Company spins off any Subsidiary by distributing to
         the Company's shareholders as a dividend or otherwise any stock or
         other securities of the Subsidiary, the Company shall reserve until the
         end of the term of the Option enough such shares or other securities
         for delivery to the Buyer upon any exercise of the rights represented
         by the Option to

                                       26
<PAGE>

         the same extent as if the Buyer owned of record all Common Stock or
         other securities subject to the Option on the record date for the
         distribution of the Subsidiary's shares or other securities.

Upon each adjustment or readjustment required by this Section 6.10(f), the
Company shall promptly compute such adjustment or readjustment and furnish to
the Buyer a certificate setting forth such adjustment or readjustment and
showing in detail the facts giving rise to the adjustment or readjustment. Upon
the Buyer's written request, the Company also shall furnish to the Buyer a
similar certificate setting forth (1) such adjustments and readjustments, (2)
the Option Price in effect on the date of the certificate, and (3) the number of
Shares and the amount of any other property that the Buyer would receive upon
exercising the Option.

         (g) The Buyer may not transfer, sell or make any other disposition of
the Option (other than in connection with a succession to or transfer of its
business as a whole), or grant any Lien respecting any of its rights under the
Option, without the Company's prior consent.

         (h) By accepting the Option, the Buyer agrees that the Option and the
Shares or other securities issuable upon exercise of the Option may be offered
or sold, only in compliance with the Act and all applicable state and securities
laws. The Buyer hereby agrees to comply with this Section 6.10(h) with respect
to any resale or other disposition of such securities. The Buyer may offer or
sell any such securities only in accordance with (1) an effective registration
statement under the Act; (2) SEC Rule 144; or (3) another exemption from the
registration requirements of the Act and all applicable state securities laws
demonstrated, to the Company's reasonable satisfaction, by an opinion of
securities counsel reasonably acceptable to the Company. The Company may make a
notation on its records, and on the certificates for any Shares or other
securities issued upon the exercise of the Option, to implement the restrictions
set forth in this Section 6.10(h). The Buyer represents and warrants that it is
acquiring the Option, and will acquire the Shares subject thereto, for its own
account and not on behalf of any other Person, and that it is an "accredited
investor," as that term is defined in SEC Regulation D. By accepting the Option,
the Buyer acknowledges that the Company is granting the Option to the Buyer in
reliance on the Buyer's foregoing representations and warranties and the terms
of this Section 6.10(h). Before allowing any transferee of any of the Buyer's
rights under the Option to exercise this Option, the Company may, in its sole
discretion, require the transferee to execute and deliver representations,
warranties and acknowledgments to the Company substantially similar to those set
forth in this Section 6.10(h).

         (i) Notwithstanding anything in this Section 6.10, if an exercise of
the Option would otherwise produce a gain (as measured by the difference between
the Exercise Price and the market value, determined in accordance with Section
6.10(b), multiplied by the number of Shares as to which the Option is exercised)
in excess of (i) $520,000 minus (ii) the termination fee, if any, timely paid by
the Company pursuant to Section 6.3(b) or (c) in connection with the Triggering
Event in question, then the exercise of the Option will be effective only as to
the number of Shares which produce a gain (as so measured) equal to such
difference.

         (j) In the event the Company proposes to consummate a transaction
(however structured, including without limitation a sale of stock or a merger)
to which it is a party and which involves an acquisition of shares or equity
interest in the Company by a third Person, and immediately following such
transaction such Person together with its parents and subsidiaries
(collectively, the "Acquiring

                                       27
<PAGE>

Person") owns a majority of both the voting power and economic interest
represented by the outstanding stock of the Company on a fully-diluted basis,
then the Company (x) shall give the Buyer at least 20 days written notice of the
proposed consummation, including a summary of the transaction and a copy of all
transaction documents (which summary and documents shall be kept current by
further notices to the Buyer) and (y) if it has complied with clause (x), may at
its option, exercised by notice to the Buyer not later than five days prior to
such consummation, redeem the Option (in whole and not in part) simultaneously
with such consummation for an amount per share, paid by wire transfer of same-
day funds to the account designated by the Buyer, equal to the excess, if any,
of the Redemption Price over the Exercise Price then in effect. The "Redemption
Price" is:

                  (i) if the equity interest the Acquiring Person is acquiring
         in such consummation, together with any equity interest acquired by
         such Acquiring Person within 180 days prior to such consummation
         constitutes a majority of both the voting power and economic interest
         represented by the outstanding stock of the Company on a fully-diluted
         basis, the highest price per share paid (or to be paid upon such
         consummation) by the Acquiring Person in the course of acquiring such
         majority ownership, and

                  (ii) otherwise, the fair market value of a Share (or the other
         Property then subject to the Option) as agreed to by the Company and
         the Buyer or, in the absence of such agreement, as determined by an
         investment bank of national reputation selected by the Company from a
         list of three such banks proposed by the Buyer (on its own initiative
         or within 15 days after written request by the Company), which bank
         shall not have engaged in a transaction with, or advised with respect
         to a transaction, either the Company or the Buyer within the prior
         three years. If this clause (ii) is applicable, the Company will not
         consummate such transaction unless and until the fair market value has
         been agreed or determined pursuant to this clause (ii).

         6.11     SEC Reports. From and after the date of this Agreement until
the earlier of the termination of this Agreement pursuant to its terms or the
Effective Time, the Company will timely file all reports required to be filed by
it under the Exchange Act.

         6.12     Stock Option Plan, Stock Purchase Plan.

         (a) Prior to the Effective Time, the Company will take all actions
necessary to give effect to Section 3 of the Plan of Merger and to terminate the
Company's 1990 Long Term Incentive Plan and Old Carleton's 1994 Stock Option
Plan, effective immediately after the Effective Time.

         (b) Each employee who has elected to participate in the Company's
Employee Stock Purchase Plan (as though it had not expired) shall receive,
pursuant to a letter agreement between the Company and such employee stating
that such payment constitutes full satisfaction of all the Company's obligations
under such Plan, an amount equal to the Merger Consideration (as defined in the
Plan of Merger) times the number of Shares which the amount held in such Plan
for such employee would have purchased under such Plan had it not expired.

         6.13     Notice of Certain Events. The Company shall notify the Buyer,
and the Buyer shall promptly notify the Company, of:

                                       28
<PAGE>

                  (i) receipt of any notice or other communication from any
         Person alleging that the consent of such Person is or may be required
         in connection with the transactions contemplated by this Agreement;

         investigation or proceeding has been commenced or, to the knowledge of
         the Company, threatened, against or involving the Company, any
         Subsidiary or the Buyer, as applicable, which, if pending on the date
         of this Agreement, would have been required to have been disclosed
         pursuant to Section 2.18 or which relates to the transactions
         contemplated by this Agreement;

                  (iv) the occurrence or non-occurrence of any event the
         occurrence or non-occurrence of which would be likely to cause any
         representation or warranty of it (and, in the case of the Buyer, of
         Buyer Subsidiary) contained in this Agreement to be untrue or
         inaccurate; and

                  (v) any failure of the Company, the Buyer or Buyer Subsidiary,
         as the case may be, to comply with or satisfy any covenant, condition
         or agreement to be complied with or satisfied by it hereunder.

The delivery of any notice pursuant to this Section 6.13 shall not limit or
otherwise affect the remedies available to the party receiving such notice.

         6.14 Takeover Statutes. If any Takeover Statute is, becomes or may
become applicable to the Merger or any of the transactions contemplated hereby,
each of the Buyer, Buyer Subsidiary and the Company, and their respective Boards
of Directors, shall grant such approvals and take such lawful actions as are
necessary to ensure that the Merger and such transactions may be consummated as
promptly as practicable on the terms contemplated hereby, and to the extent
permitted by law otherwise act to eliminate the effects of such statute and any
regulations promulgated thereunder on the Merger and such transactions or, if
they cannot be eliminated, to minimize them.

         6.15 Pay-Off. The Company will, upon the request of the Buyer,
cooperate with the Buyer in arranging the pay-off or refinancing of any
indebtedness of the Company set forth in Schedule 2.6(b) which the Buyer, in its
business discretion, desires to pay off or refinance in connection with the
consummation of the transactions contemplated hereby.

     This Plan of Merger (this "Plan of Merger") dated November __, 1999 is
entered into by DM Acquisition Corp., a Minnesota corporation ("Buyer
Subsidiary"), and Carleton Corporation, a Minnesota corporation (the "Company").
Buyer Subsidiary is a wholly-owned subsidiary of Oracle Corporation, a Delaware
corporation (the "Buyer").

     The Company desires to merge with Buyer Subsidiary, and the Buyer and Buyer
Subsidiary desire to have Buyer Subsidiary merged into the Company (the
"Merger"), on the terms and conditions set forth herein and in the Agreement of
Merger dated the date hereof among the parties to this Plan of Merger and the
stockholders of the Company setting forth certain representations and
warranties, covenants and conditions in connection with the Merger (the "Merger
Agreement").  Capitalized terms used herein without definition have the meanings
stated in the Merger Agreement.

Section 1.  Merger

     1.1    Merger.  Upon the filing of articles of merger with respect to this
Plan of Merger with the Minnesota Secretary of State in accordance with
Minnesota law (the "Effective Time"), Buyer Subsidiary shall be merged with and
into the Company and the separate corporate existence of Buyer Subsidiary shall
cease.  The Company shall be the surviving corporation in the Merger (the
"Surviving Corporation") and the separate corporate existence of the Company,
with all its purposes, objects, rights, privileges, powers, immunities and
franchises, shall continue unaffected and unimpaired by the Merger.

     1.2    Articles of Incorporation.  At the Effective Time, the articles of
incorporation of the Company shall be the articles of incorporation of the
Surviving Corporation, subject always to the right of the Surviving Corporation
to amend its certificate of incorporation after the Effective Time in accordance
with the laws of the State of Minnesota, and shall not be amended by virtue of
the Merger.

     1.3    By-Laws. At the Effective Time, the by-laws of Buyer Subsidiary
shall be the by-laws of the Surviving Corporation and shall not be amended by
the Merger.

     1.4    Directors and Officers. At the Effective Time, the directors of
Buyer Subsidiary immediately prior to the Effective Time shall be the directors
of the Surviving Corporation, and the officers of Buyer Subsidiary immediately
prior to the Effective Time shall be the officers of the Surviving Corporation,
in each case until their successors have been elected and qualified or until
otherwise provided by law.

Section 2.  Effects on Capital Stock

     2.1    Company Shares Owned by Company or the Buyer. At the Effective Time,
all of the shares of capital stock of the Company ("Shares") that are owned
directly or indirectly by the Company or any subsidiary of the Company and any
Shares owned by the Buyer, Buyer Subsidiary
<PAGE>

or any other subsidiary of the Buyer shall be canceled and no consideration
shall be delivered therefor.

     2.2    Company Shares.  At the Effective Time, all of the shares of Common
Stock, $.25 par value per share, of the Company ("Shares"), other than any
Shares as to which dissenters' rights under Section 302A.473 of the Minnesota
Business Corporation Act are perfected ("Dissenters' Shares") and other than
those referred to in Section 2.1, shall be converted into the right to receive,
in accordance with this Plan of Merger, in cash, without interest, $2.45 per
Share (the "Merger Consideration").

     2.3    Common Stock of Buyer Subsidiary.  At the Effective Time, all of the

     3.1    Stock Options.  At the Effective Time, each option outstanding under
the Company's 1990 Long Term Incentive Plan and Old Carleton's 1994 Stock Option
Plan will be converted into the right to receive the Spread Amount.  The "Spread
Amount" is (i) the excess, if any, of the Merger Consideration over the exercise
price of such option times (ii) the number of Shares then subject to such option
(determined, with respect to option holders who are employees of the Company at
the Effective Time, without regard to any vesting or deferred exercisability
provisions), net of applicable withholdings.

     3.2    Warrants.  At the Effective Time, each warrant for the purchase of
Shares will be converted into the right to receive (i) the excess, if any, of
the Merger Consideration over the exercise price of such warrant times (ii) the
number of Shares then subject to such warrant.

     3.3    Employee Stock Purchase Plan.  At the Effective Time, each employee
who has elected to participate in the Company's Employee Stock Purchase Plan as
though it applied to shares in addition to those set forth therein shall be
entitled to receive, pursuant to a letter agreement between the Company and such
employee stating that such payment constitutes full satisfaction of all the
Company's obligations under such Plan, an amount equal to the Merger
Consideration times the number of Shares which the amount held in such Plan for
such employee would have purchased under such Plan had applied to such shares.

Section 4.  Surrender of Certificates

     4.1    Paying Agent. Prior to the Effective Time, the Buyer shall designate
a bank or trust company to act as agent for the holders of the Shares in
connection with the Merger (the "Paying Agent") to receive the funds to which
the holders of the Shares shall become entitled pursuant to Section 2.2. The
Buyer shall, from time to time, make available to the Paying Agent funds in
amounts and at times necessary for the payment of the Merger Consideration in
the amounts and at the times provided herein. All interest earned on such funds
shall be paid to the Surviving Corporation.

     4.2    Surrender Procedures.  As soon as reasonably practicable after the
Effective Time, the Paying Agent shall mail each holder of record of a
certificate or certificates, which immediately

                                       2
<PAGE>

prior to the Effective Time represented outstanding Shares (the "Certificates"),
whose shares were converted pursuant to Section 2.2 into the right to receive
the Merger Consideration (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon delivery of the Certificates to the Paying Agent and shall be in
such form and have such other provisions as the Buyer and the Company may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for payment of the Merger Consideration. Upon
surrender of a Certificate for cancellation to the Paying Agent or to such other
agent or agents as may by appointed by the Buyer, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor the Merger Consideration for each Share formerly
represented by such Certificate and the Certificate so surrendered shall
forthwith be canceled. If payment of the Merger Consideration is to be made to a
person other than the person in whose name the surrendered Certificate is
registered, it shall be a condition of payment that the Certificate so
surrendered shall be properly endorsed or shall be otherwise in proper form for
transfer and that the person requested in such payment shall have paid any
transfer and other taxes required by reason of the payment of the Merger
Consideration to a person other than the registered holder of the Certificate
surrendered or shall have established to the satisfaction of the Surviving
Corporation that such tax either has been paid or is not applicable. Until
surrendered as contemplated by this Section 4.2, each Certificate shall be
deemed at any time after the Effective Time to represent only the right to
receive the Merger Consideration as contemplated by this Section 4.2. The right
of any holder of Shares to receive the Merger Consideration shall be subject to
and reduced by any applicable withholding obligation.

     4.3    Transfer Books; No Further Ownership Rights in the Shares.  At the
Effective Time, the stock transfer books of the Company shall be closed and
thereafter there shall be no further registration of transfers of the Shares on
the records of the Company.  From and after the Effective Time, the holders of
Certificates evidencing ownership of the Shares outstanding immediately prior to
the Effective Time shall cease to have any rights with respect to such Shares,
except as otherwise provided for herein or by applicable law.

     4.4    Termination of Fund; No Liability.  At any time following six months
after the Effective Time, the Surviving Corporation shall be entitled to require
the Paying Agent to deliver to it any funds (including any interest received
with respect thereto) which had been made available to the Paying Agent and
which have not been disbursed to holders of Certificates, and thereafter such
holders shall be entitled to look to the Surviving Corporation (subject to
abandoned property, escheat or other similar laws) only as general creditors
thereof with respect to the Merger Consideration payable upon due surrender of
their Certificates, without any interest thereon.  In no event shall the Buyer,
the Surviving Corporation or the Paying Agent shall be liable to any holder of a
Certificate for Merger Consideration delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.

     4.5    Lost, Stolen or Destroyed Certificates. In the event any Certificate
shall have been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the registered holder thereof or such holder's duly authorized
attorney-in-fact, the Surviving Corporation may pay, or authorize the Paying
Agent to pay, the Merger Consideration with respect thereto, subject to Section
4.4 if applicable, provided that the Board of Directors of the Surviving
Corporation may, it its discretion and as a condition precedent to the payment
thereof, require the registered holder(s) and/or beneficial owner(s) of such
Certificate to give the Surviving Corporation a bond in such sum as it

                                       3
<PAGE>

may direct as indemnity against any claim that may be made against the Surviving
Corporation, the Company, the Buyer Subsidiary with respect to the Certificate
alleged to have been lost, stolen or destroyed.

Section 5.  Dissenter's Rights

     If any Dissenting Shares shall be entitled to be paid the "fair value" of
such Shares, as provided in Section 302A.473 of the Minnesota Business
Corporation Act, the Company shall give the Buyer and Buyer Subsidiary notice
thereof and the Buyer and Buyer Subsidiary shall have the right to participate
in all negotiations and proceedings with respect to any such demands.  The
Surviving Corporation shall not, except with the prior written consent of the
Buyer or Buyer Subsidiary, voluntarily make any payment with respect to, or
settle or offer to settle, any such demand for payment.  If any Dissenting
Shares shall fail to perfect or shall have effectively withdrawn or lost the
right to dissent, such Dissenting Shares shall thereupon be treated as though
such Dissenting Shares had been converted into the right to receive the Merger
Consideration pursuant to Section 2.2.

Section 6.  Miscellaneous

     6.1    Other Agreements Superseded; Waiver and Modification, Etc. This Plan
of Merger, together with the Merger Agreement, supersedes all prior agreements
or understandings, written or oral, of the Company and the Buyer and Buyer
Subsidiary relating to the acquisition of the Company or its business and
incorporates the entire understanding of the parties with respect thereto. The
parties to this Plan of Merger make no representations or warranties with
respect to any matter, except as expressly set forth in the Merger Agreement.
The Plan of Merger may be amended or supplemented only by a written instrument
signed by the party against whom the amendment or supplement is sought to be
enforced. The party benefited by any condition or obligation may waive the same,
but such waiver shall not be enforceable by another party unless made by written
instrument signed by the waiving party and only to the extent expressly stated
therein.

     6.2    Interpretation.  The headings used in this Plan of Merger are
provided for convenience only and this Plan of Merger shall be interpreted as
though they did not appear herein. References in this Plan of Merger to sections
refer, unless otherwise specified, to the designated section of this Plan of
Merger.

     6.3    Law Governing.  Except as to matters manditorily governed by the
Minnesota Business Corporation Act, this Plan of Merger shall be construed in
accordance with and governed by the laws of the State of California applicable
to contracts made and to be performed in California.

     6.4    Time of Essence.  Time is of the essence of this Plan of Merger and
all of the terms, conditions and provisions hereof.

     6.5    Counterparts.  This Plan of Merger may be executed in any number of
counterparts and each such executed counterpart shall be deemed to be an
original instrument, but all such executed counterparts together shall
constitute one and the same instrument.  One party may execute one or more
counterparts other than that or those executed by another party, without thereby
affecting the effectiveness of any such signatures.

                          Voting and Proxy Agreement

     This Voting and Proxy Agreement dated November 8, 1999 is entered into
between _________________ (the "Stockholder"), and Oracle Corporation, a
Delaware corporation (the "Buyer").

     In connection with the parties' entry into this Agreement, Carleton
Corporation, a Minnesota corporation (the "Company"), the Buyer and DM
Acquisition Corp., a Minnesota corporation and a wholly-owned subsidiary of the
Buyer (the "Buyer Subsidiary") are entering into an Agreement of Merger dated
the date hereof (the "Merger Agreement") pursuant to which the Buyer Subsidiary
will be merged (the "Merger") into the Company, which will thereupon become a
wholly-owned subsidiary of the Buyer.  The Merger has been approved by the
Company's board of directors, and will be submitted to the stockholders of the
Company for approval.  The Stockholder is a stockholder of the Company, and
enters into this Agreement in such capacity.

     The Buyer would not enter into the Merger Agreement but for the execution
of this Agreement and the accompanying irrevocable proxy, and the Stockholder
desires to induce the Buyer to enter into the Merger Agreement.

     Capitalized terms used herein without definition have the meanings stated
in the Merger Agreement.

     Accordingly, the Stockholder hereby agrees as follows:

     1.  Voting for Merger.

         (a)  Subject to the terms and conditions hereof, the Stockholder will
vote the Subject Shares (i) in favor of the Merger at any stockholder meeting or
solicitation of written consents with respect thereto, or any direct or remote
adjournment thereof, and (ii) against any Third Party Transaction at any
stockholder meeting or solicitation of written consents with respect thereto, or
at any direct or remote adjournment thereof. "Subject Shares" means (i) the
shares of common stock of the Company listed below the Stockholder's signature
hereof (the "Listed Shares") and (ii) any shares of capital stock of the Company
in which he directly or indirectly has Beneficial Ownership and has the power to
vote such shares. "Beneficial Ownership" has the meaning stated in Rule 13d-3
issued by the Securities and Exchange Commission under the Securities Exchange
Act of 1934, as amended.

         (b)  Prior to the consummation of the Merger or any earlier termination
of this Agreement, Stockholder will not transfer, voluntarily or involuntarily,
any record, beneficial or security interest in, or enter into any other Contract
with respect to, any of the Listed Shares to any Person. Any purported transfer
or Contract in violation of this Section 1(b) will be null and void.

Shares are being legended as follows to the extent held in the personal name of

the right to vote, or to execute and deliver stockholder written consents, in
respect of the Subject Shares.  It is understood and agreed that such

another party hereto with any term or provision hereof on the part of such other
