vested and immediately exercisable options, under the Buyer's 1996 Nonstatutory
Stock Option Plan, to acquire a number of shares of Buyer Common Stock as set
forth on Schedule I hereto. Such new options shall have a per share option
exercise price equal to the per share exercise price as set forth on Schedule I

in the number of shares of Buyer Common Stock issued as a result of any cash
proceeds received by the Company from the date hereof to the Closing pursuant to
the exercise of any Company Options.

       (d)  Fractional Shares. No fraction of a share of Buyer Common Stock will
            -----------------
be issued, but, in lieu thereof, each Stockholder who would otherwise be
entitled to a fraction of a share of Buyer Common Stock (after aggregating all
fractional shares of Buyer Common Stock to be received by such stockholder)
shall be entitled to receive from Buyer an amount of cash (rounded to the
nearest whole cent) equal to the product of (i) such fraction, multiplied by
(ii) the average closing price of a share of Buyer Common Stock for the five (5)
consecutive trading days ending on the trading day immediately prior to the
Closing Date, as reported on the Nasdaq National Market (the "Closing Fair
Market Value").
    
  1.5  Surrender of Certificates.
       -------------------------

       (a)  Surrender of Certificates. Each Stockholder shall deliver to Buyer

claim that may be made against Buyer with respect to the Certificates alleged to

            ---------------------- 
Common Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the Certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Buyer or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Buyer Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Buyer or any
agent designated by it that such tax has been paid or is not payable.

  1.6  Tax Consequences. It is intended by the parties hereto that the Purchase
       ---------------- 
shall constitute a reorganization within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code").

  1.7  Taking of Necessary Action; Further Action. If, at any time after the
       ------------------------------------------   
Closing, any such further action is necessary or desirable to carry out the
purposes of this Agreement and to vest Buyer with full right, title and
possession to all Purchased Shares, each Stockholder agrees to promptly, at its
own expense, take all such lawful and necessary action.

subject matter thereof, the applicable royalty or other fees and the term
thereof. The execution and delivery of this Agreement by the Company, and the
consummation of the transactions contemplated hereby, will neither cause the

agreement, nor entitle any other party to any such license, sublicense or
agreement to terminate or modify such license, sublicense or agreement. Except

have been asserted or are threatened by any person, nor is the Company aware of

infringes on any copyright, patent, trade mark, service mark, trade secret or
other proprietary right of others, (ii) against the use by the Company of any

conducted or as proposed to be conducted does not infringe, any copyright,
patent, trademark, service mark, trade secret or other proprietary right of any
third party. The Company is not aware of any material unauthorized use,
infringement or misappropriation of any of the Company

<PAGE>
 
        (a) Investment Intent. The Seller is acquiring the Buyer Common Stock or
            -----------------
in the case of the Option Holders options therefor (collectively, the
"Securities") for the Seller's own account for investment purposes only and not
with a view to, or for resale in connection with any "distribution" thereof in
violation of the Securities Act of 1933, as amended (the "Securities Act").
     
        (b) Information About Buyer. The Seller is aware of Buyer's business

            -------------------------
Securities have not been registered under the Securities Act in reliance upon a
specific exemption therefrom.

        (e) Held Indefinitely. The Seller further understands that the
            -----------------
Securities may be disposed of only if subsequently registered under the
Securities Act or unless an exemption from registration is otherwise available.

             -------- 
promulgated under the Securities Act.

        (g) No Public Market. The Seller further understands that at the time
            ----------------
the Seller wishes to sell the Securities there may be no public market upon
which to make such a sale, and that, even if such a public market then exists,
Buyer may not be satisfying the current public information requirements of Rule
144, and that, in such event, the Seller would be precluded from selling the
Securities under Rule 144 even if the two-year minimum holding period had been
satisfied.

  3.4   Standstill and Restrictions on Transfer.  Seller agrees to abide by the
        ---------------------------------------

Buyer, by Seller.

ownership by short sale or otherwise, or other disposition, directly or
indirectly (such actions being collectively referred to herein as a "Sale") of
any of Buyer Common Stock (on a fully diluted basis, giving effect to all
options) to be received by Seller hereunder.

        (d) If Seller is a partnership, then the term "Sale" as used in
paragraph (c) above shall not be deemed to include any distribution to Seller's
partners, provided that if any recipient of any such distribution will receive
shares of Buyer Common Stock having a fair market value of 1% or more of the
fair market value of all the shares of Company Capital Stock presently
outstanding, Seller is not aware of any Plan on the part of such recipient to
engage in a Sale of any of the shares of Buyer Common Stock (on a fully diluted
basis, giving effect to all options) to be received by such recipient in such
distribution.

aggregate fair market value of all shares of outstanding Company Capital Stock
immediately prior to such Closing.

        (f) Seller understands that Buyer and its affiliates, as well as legal
counsel to Company and Buyer (in connection with rendering their opinions that

Code) will be relying on (a) the truth and accuracy of the representations
contained herein and (b) Seller's performance of the obligations set forth
herein.

  4.4   SEC Documents; Buyer Financial Statements.  Buyer has furnished or made
        -----------------------------------------
available to the Founders or legal counsel to the Company true and complete
copies of all reports or registration statements filed by it with the SEC since
December 12, 1995, all in the form so filed (all of the foregoing being
collectively referred to as the "SEC Documents").  As of their respective filing
dates, the SEC Documents complied in all material respects with the requirements
of the Securities Act or the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), as the case may be, and none of the SEC Documents contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements made therein, in light
of the circumstances in which they were made, not misleading, except to the
extent corrected by a document subsequently filed with the SEC.  The financial
statements of Buyer, including the notes thereto, included in the SEC Documents
(the "Buyer Financial Statements") comply as to form in all material respects
with applicable accounting requirements and with the published rules and
regulations of the SEC with respect thereto, have been prepared in accordance
with GAAP consistently applied (except as may be indicated in the notes thereto
or, in the case of unaudited statements, as permitted by Form 10-Q of the SEC)
and present fairly the consolidated financial position of Buyer at the dates
thereof and the consolidated results of its operations and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal
audit adjustments).  There has been no change in Buyer accounting policies
except as described in the notes to Buyer Financial Statements; provided,
however, Buyer may have restated or may restate one or more of Buyer Financial
Statements to reflect acquisitions entered into subsequent to the respective
dates thereof.

  4.5   No Material Adverse Change. Since the date of the balance sheet included

adverse change in the financial condition, liabilities, assets or business of
Buyer; (b) any amendment or change in the Certificate of Incorporation or Bylaws
of Buyer (other than restatements of the Certificate or Incorporation which did
not require stockholders' approval); or (c) any damage to, destruction or loss
of any assets of Buyer, (whether or not covered by insurance) that materially
and adversely affects the financial condition or business of Buyer.

  4.6   Litigation.  There is no action, suit, proceeding, claim, arbitration or
        ----------

or materially delay any of the transactions contemplated by this Agreement or,
if adversely determined, is reasonably likely to have a material adverse effect
on the financial condition or business of Buyer as a whole.

  4.7   Brokers' and Finders' Fees.  Other than pursuant to a Letter Agreement
        --------------------------
dated December [__], 1996 between the Buyer and Cowen & Co., Buyer has not
incurred, now will incur, directly or indirectly, any liability for brokerage or
finders' fees or agents' commissions or any similar charges in connection with
this Agreement or any transaction contemplated hereby.

least one significant historic business line of the Company, or to use at least
a significant portion of the Company's historic business assets in a business,
in each case within the meaning of Treasury Regulation Section 1.368-1(d). Buyer
will use all reasonable efforts, and will cause the Surviving Corporation to use
all reasonable efforts, to take no action that would cause the Purchase not to
constitute a reorganization within the meaning of Section 368 of the Code.

  4.9   Employee Benefit Plans; ERISA.

to Buyer, and Buyer shall give prompt notice to the Sellers, of (i) the
occurrence or non-occurrence of any event, the occurrence or non-occurrence of
which is likely to cause any representation or warranty of such Seller or Buyer,
respectively, contained in this Agreement to be untrue or inaccurate at or prior

Company who become employees of Buyer or Surviving Corporation, or who are
employees of the Company, in each case, on or after the Closing (the
"Employees"), provide coverage under welfare benefit plans, programs and
arrangements (the "Welfare Plans") providing benefits not substantially less
favorable in the aggregate to the Employees than the Welfare Plans covering the
other similarly situated employees of Buyer as in effect immediately prior to
the Closing, including (without limitation) group health plans which do not
exclude or limit the coverage of the Employees on account of waiting periods or
preexisting conditions, and which have in all material respects identical or
superior coverage in terms of employee participation.  The Employees shall be

Buyer in the same manner as Buyer's similarly situated employees.  For purposes

the date of grant and 1/48th vesting monthly thereafter, except for each such

preceding the Closing Date.

instruments and do and perform such other acts and things as may be reasonably
necessary or desirable for effecting completely the consummation of this
Agreement and the transactions contemplated hereby.

        ------------------
management and its independent auditors to facilitate on a timely basis (i) the
preparation of financial statements (including pro forma financial statements if
required) as required by Buyer to comply with applicable SEC regulations and
(ii) the review of the Company's audit work papers for up to the past three
years, including the examination of selected interim financial statements and
data.

        -------------------------
outstanding principal amounts, together with all accrued and unpaid interest
thereon, due under the Revolving Credit and Security Agreement, dated August 6,
1996, among the Company, as borrower, Wexford Capital and Wexford Overseas, as

Corporation shall pay to Wexford $45,000 in reimbursement of internal and
external counsel fees and $25,000 in payment for accounting and Schedules

shall be deemed to be Third Party Expenses for the purposes of Section 6.3
(notwithstanding anything to the contrary contained in Section 6.3).
Simultaneously, Wexford shall deliver all necessary documents requested by Buyer
to terminate all security interests, reconvey all pledged or assigned assets and
release all collateral pledged in connection with the foregoing agreement.

        ------------------
under that certain Stockholders Agreement, dated as of August 6, 1996, among any
or all of them or between or among any or all of them and the Company, and any
other rights they may have under any other agreements, that are inconsistent
with their rights and obligations under the Agreement and hereby agree that all
such agreements shall terminate without further action on the part of the
Sellers upon the Closing.

                                  ARTICLE VIII

                  SURVIVAL OF REPRESENTATIONS AND WARRANTIES;
                                INDEMNIFICATION

  8.1 Survival of Representations and Warranties. All representations and
      ------------------------------------------
warranties of the Founders and the Sellers (other than the representations of
the Sellers in Sections 3.1 and 3.2) in this Agreement or in any instrument
delivered pursuant to this Agreement shall survive the Purchase and continue
until 5:00 p.m., California time, on the date which is one year following the
Closing Date (the "Expiration Date"). The representations of the Sellers
contained in Sections 3.1 and 3.2 shall survive the Closing indefinitely.

  8.2   Indemnity for Representations of Founders.  Each of the Founders 
        -----------------------------------------
agrees to indemnify and hold harmless each of Buyer and its affiliates for any
claims, losses, liabilities, damages, deficiencies, costs and expenses,
including reasonable attorneys' fees and expenses, and expenses of investigation
and defense (hereinafter individually a "Loss" and collectively "Losses")
                                         ----                    
incurred by Buyer, its officers, directors, or affiliates (including the
Surviving Corporation) directly or indirectly as a result of any inaccuracy or
breach of a representation or warranty of the Founders contained herein or any
failure by the Founders to perform or comply with any covenant contained herein;
provided, however that the indemnification obligation of each Founder under this
Section 8.2 shall be limited to the Closing Fair Market Value of the total
consideration received by each pursuant to Article I of this Agreement (which
value in the case of Rice shall be calculated based upon the difference between
the exercise price per share of the option granted to Rice pursuant to Section
1.2 and the Closing Fair Market Value); provided that each Founder shall be
obligated for that portion of a Loss that is commensurate with the portion
received by such Founder of the aggregate Closing Fair Market Value of the
consideration received by both Founders pursuant to Section 1.2 (calculated as
aforesaid in the case of Rice), that such obligation may be satisfied by the
transfer to Buyer of shares of Buyer Common Stock delivered to Migdal in
accordance with Section 1.4(a), in the case of Migdal, or a portion or all of
the option granted pursuant to Section 1.2, in the case of Rice, having an
aggregate Closing Fair Market Value (calculated as aforesaid in the case of
Rice), equal to such obligation, and that the Founders shall have customary
rights to participate in (at their own expense) but not to control the defense
against, or any settlement of, any third party claim that could result in a
Loss, which control shall be exercised by Buyer or the Surviving Corporation
reasonably and in good faith in view of the indemnification obligation of each
Founder under this Section 8.2.

  8.3   Indemnity for Representations of Each.  Each Seller, severally and not
        -------------------------------------
jointly, agrees to indemnify and hold harmless each of Buyer and its affiliates
for any incurred by Buyer, its officers, directors or affiliates (including the
Surviving Corporation) directly or indirectly as a result of any inaccuracy or
breach of a representation or warranty of such Seller contained in Section 3 or
any failure of such Seller to perform or comply with any covenant contained
herein; provided, however, that the indemnification obligation of each Seller
under this Section 8.3 shall be limited to the Closing Fair Market Value of the
total consideration received by such Seller pursuant to Article I of this
Agreement (and may be satisfied as provided in Section 8.2 with respect to
indemnification obligations of the Founders).

                              EMPLOYMENT AGREEMENT
                              --------------------
                                        

  AGREEMENT, dated as of December 31, 1996 by and between MetaTools, Inc., a

  WHEREAS, concurrently with the execution and delivery of this Agreement, the
Company is acquiring by means of a merger transaction all of the shares of
capital stock to be issued and outstanding of Real Time Geometry Corp., a
Delaware corporation ("RTG"), of which Executive has been an executive officer
and a holder of shares of capital stock; and

  WHEREAS, the Company desires to employ Executive as an executive officer of

conditions contained in this Agreement;

  NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the parties hereto agree as follows:

  1.  Prior Agreements. Executive hereby represents and warrants to the Company
      ----------------
that all agreements, understandings or arrangements between Executive and any
other person or entity contain no terms that would be breached by Executive as a
result of, or that would in any way preclude or prohibit Executive from,
entering into this Agreement with the Company or performing any of the
responsibilities provided for in this Agreement.

  2.  Employment and Responsibilities.
      -------------------------------

      (a) General. Upon the terms and conditions herein set forth, the Company
          -------
hereby agrees to employ Executive and Executive agrees to serve as Vice
President, Senior Scientist of the Company, for the Term of Employment (as
defined in Section 3 hereof). In such capacity, Executive shall be responsible
for the research and development activities and other operations of the
Princeton Laboratory of RTG and shall have authority over the hiring and
terminating of personnel of RTG or the Company employed at the Princeton
Laboratory and over all other activities conducted by or at the Princeton
Laboratory, provided that he shall exercise such authority consistent with the
budget for the Princeton Laboratory in effect from time to time. It is the
Company's present intention that the current activity levels of the Princeton
Laboratory be maintained during the Term of Employment.

      (b) Nature of Services. Except as provided in Sections 2(c) and 2(d)
          ------------------
hereof, during the Term of Employment Executive shall, except as from time to
time may be otherwise agreed to in writing by the Company, devote his full time
and attention during 

                                      -1-
<PAGE>

diligently serve the Company, shall in all respects conform to, comply with and
execute the lawful directions and instructions given to him by the Company, and
shall diligently use his best efforts, skills and abilities to promote the
interests of the Company.

      (c)  Covenant Not to Compete.
           -----------------------

           (i) Executive shall sign a Noncompetition Agreement concurrently with
this Agreement and shall abide by the terms and conditions of the Noncompetition
Agreement. Failure to abide by the terms of the Noncompetition Agreement shall
be considered a material breach of this Agreement.

           (ii) Executive represents that he (i) is familiar with the foregoing
covenants not to solicit and not to compete, and (ii) is fully aware of his
obligations hereunder, including, without limitation, the reasonableness of the
length of time, scope and geographic coverage of these covenants.

           (iii) Executive shall sign and abide by the Company's standard
invention assignment agreement.

      (d)  Charitable or other Activities. Subject to the restrictions contained
           ------------------------------
in Section 2(c) hereof, Executive may (i) serve on corporate, civic or
charitable boards or committees, (ii) deliver lectures, fulfill speaking
engagements or teach at educational institutions, and (iii) manage personal and
immediate family investments, so long as such activities do not interfere with
the fulfillment of Executive's responsibilities hereunder.

      (e)  Place of Performance.  The principal place of employment of 
           --------------------
Executive shall be at offices maintained by the Company (or RTG) in Princeton,
New Jersey or another location within 10 miles of Princeton, New Jersey, and the
Company understands that Executive and his family shall have their permanent
residence in or around Princeton, New Jersey. Subject to the foregoing,
Executive realizes that his responsibilities hereunder shall require travel to
and the rendering of services in Carpenteria, California, where the headquarters
offices of the Company are located, and other locations.

  3.  Term of Employment. Subject to the provisions of Section 5 hereof,
      ------------------
Executive's term of employment under this Agreement shall commence on January 1,
1997 (the "Commencement Date") and shall terminate on December 31, 1999 (the
"Term of Employment").

  4.  Compensation and Other Benefits.  The Company shall pay and provide the
      -------------------------------
following compensation and other benefits to Executive during the Term of
Employment (except as otherwise provided in Section 4(b) hereof) for the
services to be provided hereunder:

                                      -2-
<PAGE>
 
      (a)  Base Salary. The Company shall pay to Executive a base salary (the
           -----------
"Base Salary") at the rate of $150,000 per annum, payable in approximately equal
installments in accordance with the customary payroll practices of the Company.
If the rate per annum of the base salary paid to Executive is increased during
the Term of Employment, such increased rate shall thereafter constitute the Base
Salary for all purposes of this Agreement.

      (b)  Stock Option and Employee Benefit Plans. During the Term of
           ---------------------------------------
Employment, Executive shall be entitled to participate in such stock option,
pension, retirement, life insurance, health and other welfare plans, programs
and benefits as are maintained by the Company from time to time for the benefit
of its executive employees (the "Plans").

      (c)  Vacation; Fringe Benefits.  During the Term of Employment, 
           -------------------------
Executive shall be entitled to four weeks of vacation per year and to any other
fringe benefits and perquisites that are accorded to its executive employees
generally by the Company from time to time (the "Fringe Benefits").

      (d)  Carpenteria Living Stipend; Reimbursement of Expenses.  As referred 
           -----------------------------------------------------
to in Section 2(e) hereof, the parties anticipate that Executive's
responsibilities hereunder shall require the rendering of services in
Carpenteria, California, where the headquarters offices of the Company are

reimbursement of Executive for accommodations, meals and other living expenses
(but not travel expenses) in respect of his rendering of services in
Carpenteria, California (the "Carpenteria Living Expenses"). The parties also
anticipate that in the course of fulfilling his responsibilities under this
Agreement, Executive will incur other reasonable travel, entertainment and other
out-of-pocket business expenses for the account of the Company. Executive shall
be entitled to reimbursement for all reasonable out-of-pocket business expenses
so incurred (other than Carpenteria Living Expenses), upon submission to the
Company of an adequate, written accounting which complies with the Company's
policies regarding reimbursement for business expenses. The travel expense
policy applicable to Executive shall be that applicable to the most senior
executives of the Company.

      (e)  Company Loan. At the Closing, the Company shall loan to Employee the
           ------------
principal amount of $2,000,000 pursuant to a note and other instruments and
agreements as shall be consistent with the terms of this Section 4(e) (the
"Loan"). The Loan shall be repayable on January 15, 2000, shall be prepayable
without penalty in whole or in part (including all accrued interest on the
principal amount prepaid), and shall bear interest at the Applicable Federal
Rate under Section 1274(d) of the Internal Revenue Code of 1986, as amended, as
reported by the Internal Revenue Service, on the date the loan is made, payable
at maturity or upon prepayment as aforesaid, and compounded semi-annually. The
Loan shall be secured by shares of Common Stock owned by Executive having a fair
market value on the date the Loan is made of not less than $2,000,000, pursuant
to arrangements that permit the release of such shares in order to permit the
sale or pledge thereof to raise after-tax proceeds to pay or prepay principal
and accrued interest on the Loan at maturity or from time 

                                      -3-
<PAGE>
 
to time before maturity. Executive shall not be personally obligated to pay any
principal of or interest on the Loan nor shall any of his assets secure payment
of the principal of and interest on the Loan, except for such shares, solely
from which the Company shall seek to realize payment in the event of any failure
of payment on the part of Executive.

      (c)  Death. If Executive dies during the Term of Employment, the Term of
           -----
Employment and any non-competition period shall terminate on the date of death
and Executive's beneficiary or estate shall be entitled to receive (i) payment

  6.  Confidentiality; Company Property.
      ---------------------------------

      (a)  Confidentiality.  Executive recognizes that the services to be 
           ---------------
performed by him hereunder are special, unique and extraordinary in that, by
reason of his employment hereunder and his association with the Company, he may
acquire or has acquired Confidential Information concerning the Company the use
or disclosure of which could cause the Company substantial loss which could not
be readily calculated and for which no remedy at law would be adequate.
Accordingly, Executive agrees that he will not at any time, except in
fulfillment of his responsibilities hereunder or with the written consent of the
Company disclose any Confidential Information that he may learn or has learned
by reason of his employment or association with the Company or use any such
information for his own personal benefit or gain. The term "Confidential
Information" means information not previously disclosed to the public or to the
trade by the Company's management with respect to the Company's products,
facilities and methods, trade secrets and other intellectual property, systems,
procedures, manuals, confidential reports, price information, customer lists,
financial information (including the revenues, costs or profits associated with
any of the Company's activities or products), business plans, prospects,
opportunities or other information. Confidential Information shall not include
information which (i) is or becomes generally available to the public other than
as a result of disclosure by Executive in violation of this Section 6(a) or (ii)
Executive is required to disclose under any applicable laws, regulations or
directives of any government agency, tribunal or authority having jurisdiction
in the matter or under subpoena or other process of law. Executive understands
and agrees that the rights and obligations set forth in this Section 6(a) shall
extend beyond the Term of Employment.

                                      -6-
<PAGE>
 
      (b)  Company Property.  Executive confirms that all Confidential 
           ----------------
Information is and shall remain the exclusive property of the Company. All
business records, papers and documents kept or made by Executive relating to the
business of the Company or any Confidential Information shall be and remain the
property of the Company. Upon the termination of the Term of Employment or upon
the request of the Company at any time, Executive shall promptly deliver to the
Company, and shall not without the prior express written consent of the Company
retain, all copies of (i) any written materials not previously made available to
the public, or (ii) records and documents made by Executive or coming into his
possession concerning any Confidential Information. Executive agrees that the
rights and obligations set forth in this Section 6(b) shall extend beyond the
Term of Employment.

      (c)  Injunctive Relief.  Without intending to limit the remedies 
           -----------------
available to the Company, Executive acknowledges that a breach of any of the
covenants contained in this Section 6 may result in material irreparable injury
to the Company for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event
of such a breach or threat thereof, the Company shall be entitled to obtain a
temporary restraining order or a preliminary or permanent injunction restraining
Executive from engaging in activities prohibited by this Section 6.

  7.  Assignability.
      -------------

      (a)  By Executive.  Neither this Agreement nor any right, duty, 
           ------------
obligation or interest hereunder shall be assignable by Executive without the
prior express written consent of the Company.

      (b)  By the Company.  This Agreement and all of the Company's rights and
           --------------
obligations hereunder may be assigned or transferred by it to any entity which
at any time by sale, merger, consolidation or other transaction acquires all or
substantially all of the assets of the Company or to which the Company transfers
all or substantially all of its assets, provided that any such assignee agrees
in writing to assume all of the obligations of the Company hereunder. Upon such
assignment or transfer, and upon such assumption, any such entity shall be
deemed to be substituted for all purposes as the Company hereunder.

  8.  Severability.  If the final determination of a court of competent
      ------------
jurisdiction declares, after the expiration of the time within which judicial
review (if permitted) of such determination may be perfected, that any term
hereof is invalid or unenforceable, (a) the remaining terms hereof shall be
unimpaired and (b) the invalid or unenforceable term shall be deemed replaced by
a term that is valid and enforceable and that comes closest to implementing the
intention of the invalid or unenforceable term.

  9.  Amendment; Waiver.  This Agreement may not be modified, amended or 
      -----------------
waived in any manner except by an instrument in writing signed by both parties
hereto. The waiver by either party of compliance with any provision of this
Agreement by the other party shall not operate or be construed as a waiver of
any other provision of this Agreement, or of any subsequent breach by such party
of any provision of this Agreement.

                                      -7-
<PAGE>
 
  10.  Withholding.  The Company shall be entitled to deduct and withhold all
       -----------
applicable Federal, state and local taxes which the Company is required to
deduct or withhold from any payments to or on behalf of Executive under this
Agreement.

  11.  Beneficiaries. Executive shall be entitled to select a beneficiary or
       -------------
beneficiaries to receive any compensation or benefit payable hereunder following
Executive's death, and may change such selection, in either case by giving the
Company written notice thereof.

  12.  Governing Law.  All matters affecting this Agreement, including the
       -------------
validity thereof, are to be governed by, interpreted and construed in accordance
with the laws of the State of Delaware.

       -------

requested. If addressed to Executive, the notice shall be delivered or mailed to
Executive at the address specified in the Company's personnel records or such
other address as may be specified in a notice of change of address given by
Executive to the Company, or if addressed to the Company, the notice shall be
delivered or mailed to:

given by the Company to Executive.  A notice shall be deemed given, if by
personal delivery, on the date of such delivery or, if by certified mail, on the

  14.  Merger. This Agreement supersedes all prior or contemporaneous
       ------
negotiations, commitments and agreements between the Company and Executive with
respect to the subject matter hereof, and such other negotiations, commitments
and agreements will have no further force or effect.

  15.  Counterparts.  This Agreement may be executed by either of the parties
       ------------
hereto in counterparts, each of which shall be deemed to be an original, but all
such counterparts shall together constitute one and the same instrument.

AGREES TO SUBMIT ANY CLAIMS ARISING OUT OF, RELATING TO, OR IN CONNECTION WITH
THIS AGREEMENT, ANY ASPECT OF THE EMPLOYER/EMPLOYEE RELATIONSHIP, OR THE
INTERPRETATION, VALIDITY, CONSTRUCTION, PERFORMANCE, BREACH OR TERMINATION

claim by reason of litigation, arbitration or settlement.

  21. Indemnification.  The Company agrees that if Executive is made a party or
      ---------------
is threatened to be made a party to any action,  suit or proceeding, whether

and/or any affiliate or subsidiary as a director, officer, member, employee or
agent of another corporation or of a partnership, joint venture, trust or other

serving as a director, officer, member, employee or agent, he shall be
indemnified and held harmless by the Company to the fullest extent authorized by
Delaware law, including without limitation by the advancement of his expenses,
as the same exists or may hereafter be amended, against all expenses incurred or
suffered by Executive in connection therewith, and such indemnification shall
continue as to Executive even if Executive has ceased to be an officer, director
or agent, or is no longer employed by the Company and shall inure to the benefit
of his heirs, executors and administrators.

  IN WITNESS WHEREOF, the Company has caused this Agreement to be executed
pursuant to the authority of its Board of Directors, and Executive has executed
this Agreement, as of the day and year first written above.

          (v) The Options shall be issued under the Company's 1996 Nonstatutory

The grant of the Options shall not preclude Executive from participating in
stock option plans maintained by the Company from time to time for the benefit
of its Executive Employees generally.  "Change in Control" shall mean (i) the
acquisition by any individual, entity or

                                      -3-

          (f) Reimbursement of Expenses.  The parties anticipate that in the

Loan shall be secured by all of the shares of Common Stock underlying the fully-
exercisable and vested stock options received by Executive under Section 1.2 of
the Stock Purchase Agreement (as defined below) and held by Executive as of the
date the Loan is made, pursuant to arrangements that permit the release of
shares underlying such options in order to permit the sale or pledge thereof to
raise after-tax proceeds to pay or prepay principal and accrued interest on the
Loan at maturity or from time to time before maturity.  Executive shall not be
personally obligated to pay any principal of or interest on the Loan nor shall
any of his assets secure payment of the principal of and interest on the Loan,
except for such shares underlying such options, solely from which the Company
shall seek to realize payment in the event of any failure of payment on the part

(rather than when normally payable) a pro rata portion of the Annual Bonus (with
respect to only the first year of the Term of Employment) corresponding to the
portion of the year occurring prior to the date of such termination.

              (ii) "Cause" shall mean (A) the commission of an act of fraud or
embezzlement which results in loss, damage or injury to the Company, whether

arrest, indictment or filing of charges relating to a felony or misdemeanor,
either in connection with the performance of the Executive's obligations to the
Company or which shall adversely affect the Executive's ability to perform such
obligations; (D) gross negligence, breach of fiduciary duty or material breach
of the terms of this Agreement; or (E) the commission of an act which
constitutes unfair competition with the Company.  "Good Reason" shall mean a

receipt by Executive of written notice of termination.  The date of termination
of the Term of Employment by Executive under this Section 5(a) shall be 60
calendar days after receipt by the Company of written notice of termination.

of all business expenses incurred through the date of termination, (D) payment
of all vacation pay not previously paid, and (E) continuation of such coverage
for Executive and Executive's immediate family as was in effect on the date of
termination under any of the Plans, or comparable benefits, commencing on the
date of such termination and ending on December 31, 1999; provided, however,
that such coverage shall cease, with respect to any or all of the Plans, when
Executive is covered by an employee plan or program providing substantially
similar or more generous benefits.  In the event of such termination of the Term
of Employment, the Options shall become exercisable on the date of termination
with respect to all of the shares of Common Stock subject to them.  After such

receipt by Executive of written notice of termination.  The date of termination
of the Term of Employment by Executive under this Section 5(b) shall be 30
calendar days after receipt by the Company of written notice of termination,
provided that the Good Reason specified in such notice shall not have been
remedied by the Company during such 30 calendar day period.

          (c) Death. If Executive dies during the Term of Employment, the Term
              -----
of Employment shall terminate on the date of death and Executive's beneficiary
or estate shall be entitled to receive (i) payment of the pro rata portion of
the Base Salary through and including the date of death, (ii) payment (promptly,
rather than when normally due) of a pro rata portion of the Annual Bonus
corresponding to the portion of the year occurring prior to

family as Executive is entitled to under any of the Plans.

substantially perform his responsibilities hereunder.

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

          (a) Confidentiality.  Executive recognizes that the services to be
              ---------------
performed by him hereunder are special, unique and extraordinary in that, by
reason of his employment hereunder and his association with the Company, he may
acquire or has acquired Confidential Information concerning the Company the use
or disclosure of which could cause the Company substantial loss which could not
be readily calculated and for which no remedy at law would be adequate.
Accordingly, Executive agrees that he will not at any time, except in
fulfillment of his responsibilities hereunder or with the written consent of the
Company disclose any Confidential Information that he may learn or has learned
by reason of his employment or association with the Company or use any such
information for his own personal benefit or gain.  The term "Confidential
Information" means information not previously disclosed to the public or to the
trade by the Company's management with respect to the Company's products,
facilities and methods, trade secrets and other intellectual property, systems,
procedures, manuals, confidential reports, price information, customer lists,
financial information (including the revenues, costs or profits associated with
any of the Company's activities or products), business plans, prospects,
opportunities or other information.  Confidential Information shall not include
information which (i) is or becomes generally available to the public other than
as a result of disclosure by Executive in violation of this Section 6(a) or (ii)
Executive is required to disclose under any applicable laws, regulations or
directives of any government agency, tribunal or authority having jurisdiction
in the matter or under subpoena or other process of law.  Executive understands
and agrees that the rights and obligations set forth in this Section 6(a) shall
extend beyond the Term of Employment.

          (b) Company Property.  Executive confirms that all Confidential
              ----------------
Information is and shall remain the exclusive property of the Company.  All
business records, papers and documents kept or made by Executive relating to the
business of the Company or any Confidential Information shall be and remain the
property of the Company.  Upon the

                                      -7-
<PAGE>
 
termination of the Term of Employment or upon the request of the Company at any
time, Executive shall promptly deliver to the Company, and shall not without the
prior express written consent of the Company retain, all copies of (i) any
written materials not previously made available to the public, or (ii) records
and documents made by Executive or coming into his possession concerning any
Confidential Information. Executive agrees that the rights and obligations set
forth in this Section 6(b) shall extend beyond the Term of Employment.

          (c) Assignment of Inventions.  Executive shall sign and abide by the
              ------------------------
Company's standard invention assignment agreement.

          (d) Injunctive Relief.  Without intending to limit the remedies
              -----------------
available to the Company, Executive acknowledges that a breach of any of the
covenants contained in this Section 6 may result in material irreparable injury

hereof is invalid or unenforceable, (a) the remaining terms hereof shall be
unimpaired and (b) the invalid or unenforceable term shall be deemed replaced by
a term that is valid and enforceable and that comes closest to implementing the
intention of the invalid or unenforceable term.

          -----------------
waived in any manner except by an instrument in writing signed by both parties

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

and/or any affiliate or subsidiary as a director, officer, member, employee or
agent of another corporation or of a partnership, joint venture, trust or other

indemnified and held harmless by the Company to the fullest extent authorized by
Delaware law, including without limitation by the advancement of his expenses,

suffered by Executive in connection therewith, and such indemnification shall

or agent, or is no longer employed by the Company and shall inure to the benefit
of his heirs, executors and administrators.

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

                            NONCOMPETITION AGREEMENT
                            ------------------------

     This NONCOMPETITION AGREEMENT, dated the 31st day of December, 1996 (the
"Agreement") is made as of the Effective Date indicated below by and between
MetaTools, Inc., a Delaware corporation (MetaTools), and Alexander Migdal (the
"Founder").

                                   BACKGROUND
                                   ----------

     This Agreement is entered into in connection with and is ancillary to a
Stock Purchase Agreement dated as of December 20, 1996 (the "Stock Purchase
Agreement") between MetaTools and certain stockholders and option holders of
Real Time Geometry Corp., a Delaware corporation ("RTG"), pursuant to which
MetaTools has acquired RTG on the date hereof (the "Effective Date").

     Founder is a founder, stockholder and executive of RTG and has been
actively involved in the development and marketing of RTG's products. MetaTools
intends to continue the business of RTG after the Effective Date and integrate
such business into MetaTools's ongoing business. To preserve and protect the
assets of RTG, including RTG's goodwill, customers and trade secrets of which
Founder has, and will, in his role as an employee of MetaTools, have knowledge,
and to preserve and protect MetaTools's goodwill and business interests going
forward, and in consideration for MetaTools's entering into and performing under
the Stock Purchase Agreement, Founder has agreed to enter into this Agreement.

     Founder and MetaTools believe the limitations as to time, geographical area
and scope of activity contained in this Agreement hereof are reasonably
necessary to, and no greater than that required to, protect the goodwill and
business interests purchased by MetaTools.

     1. Consideration. In consideration for Founder's performance pursuant to
        -------------
the terms and conditions of this Agreement, MetaTools shall (1) purchase all of
the shares of RTG owned by Founder pursuant to the Stock Purchase Agreement and
(2) pay Founder (i) $300,000 upon the execution of this Agreement and (ii)
$150,000 on each of the first and second anniversary dates of this Agreement.

     2. Noncompete. For three years following the Effective Date, or one year
        ----------
from the termination of employment of Founder by MetaTools, whichever is longer,
Founder will not individually or as an employee, partner, officer, director or
stockholder or in any other capacity whatsoever of or for any person, firm,
partnership, company or corporation other than MetaTools or its subsidiaries:

                                      -1-
<PAGE>
 
     (a) Own, manage, operate, sell, control or participate in the ownership,
management, operation, sales or control of any business engaged, in the
geographical areas referred to in Section 3 below, in the design, research,
development, marketing, sale, or licensing of any product that is substantially
similar to or competitive with any product created, distributed or known by
Founder to be under development by MetaTools or any of its subsidiaries prior to
the termination of Founder's employment with MetaTools;

     (b) Own, manage, operate, sell, control or participate in the ownership,
operation, sales or control of any business engaged, in the geographical areas
referred to in Section 3 below, in the design, research, development, marketing,
sale, or licensing of any product that is substantially similar to or
competitive with the products of MetaTools or any of its subsidiaries;

     (c) Directly or indirectly develop any product that is substantially
similar to or competitive with any other products the creation or development of
which he participated in during Founder's employment with RTG, MetaTools or any
of its subsidiaries; or

     (d) Recruit, attempt to hire, solicit, assist others in recruiting or
hiring, or refer to others concerning employment, in or with respect to the
geographical areas referred to in Section 3 below, any person who is an employee
of MetaTools or any of its subsidiaries or induce or attempt to induce any such
employee to terminate his employment with MetaTools or any of its subsidiaries.

     3. Geographic Area. The geographical areas in which the restrictions
        ---------------
provided for in this Agreement apply include all cities, counties and states of
the United States, and all other countries, in which MetaTools or any of its
subsidiaries has engaged in licensing or sales or otherwise conducted business
or selling or licensing efforts at any time during the two years prior to the
Effective Date hereof or during the term of this Agreement. The agreement not to
compete in each such geographic subdivision is a separate and severable
agreement from all such other agreements. Founder acknowledges that the scope
and period of restrictions and the geographical area to which the restrictions
imposed in this Section 3 applies are fair and reasonable and are reasonably
required for the protection of MetaTools and that this Agreement accurately
describes the business to which the restrictions are intended to apply.

     4. Injunctions. Founder acknowledges that any breach of the covenants of
        -----------
this Agreement will result in immediate and irreparable injury to MetaTools and,
accordingly, consents to the application of injunctive relief and such other
equitable remedies for the benefit of MetaTools as may be appropriate in the
event such a breach occurs or is threatened. The foregoing remedies will be in
addition to all other legal remedies to which MetaTools may be entitled
hereunder, including, without limitation, monetary damages.

a waiver of any term of this Agreement or of that party's right to require

2.   REGISTRATION RIGHTS

     2.1  Demand Registration Rights.
          --------------------------

          (a) Upon the written request to register Registrable Securities by the
holders of at least forty percent (40%) of the Registrable Securities, Company
shall within ten (10) days of receipt of such request deliver written notice of
such request to all Persons owning Registrable Securities who shall have thirty
(30) days to indicate in writing their desire to be included in such
registration. Company will use its best efforts to expeditiously effect the
registration of all Registrable Securities whose holders request participation
in such registration under the Securities Act, but only to the extent provided
for in the following provisions of this Article 2; provided, however, that
Company shall not be required to effect registration pursuant to requests under
Section 2.1 hereof more than once for the holders of the Registrable Securities
as a group and unless the registration can reasonably be expected to result in
an aggregate sales price to the public of at least One Million Five Hundred
Thousand Dollars ($1,500,000).

          (b) Whenever a requested registration pursuant to 2.1(a) is for an
underwritten offering, only Registrable Securities which are to be included in
the underwriting may be included in the registration, and, if the managing
underwriting determines in good faith that the number of Registrable Securities
so included which are to be sold by the holders of the Registrable Securities is
limited due to market conditions, the parties with Registrable Securities in
such underwriting and registration shall share pro rata in

                                      -2-
<PAGE>
 
the number of such Registrable Securities being underwritten and registered for
their account, such sharing to be based on the number of all Registrable
Securities held by such holders, respectively. Except as permitted herein,
Company may not cause any other registration of securities for sale for its own
account (other than a registration effected solely to implement an employee
benefit plan or a transaction to which Rule 145 of the Commission is applicable)
to become effective less than ninety (90) days after the effective date of any
registration required pursuant to Section 2.1.

          (c) Company shall file a registration statement covering the
Registrable Securities requested to be registered pursuant to this Section 2.1
or Section 2.10 as soon as practical, but in any event within sixty (60) days
after receipt of such request or requests; provided, however, that if Company
shall furnish to the requesting Purchasers a certificate signed by the President
of Company stating that in the good faith judgment of at least two-thirds of the
members of the Board of Directors it would be seriously detrimental to Company
and its shareholders for such registration statement to be filed at the date
filing would be required and it is therefore essential to defer the filing of
such registration statement, Company shall have an additional period of not more
than one hundred twenty (120) days after the expiration of the initial sixty
(60) day period within which to file such registration statement. Such right to
delay a request may be exercised by Company not more than once in any two (2)
year period. Nothing in this Section 2.1(c) shall preclude a holder of
Registrable Securities from enjoying registration rights which it might
otherwise possess under Section 2.2 hereof.

     2.2 Piggyback Registration. If Company at any time proposes to register any
         ----------------------
of its securities under the Securities Act, either for its own account or the
account of a security holder or holders, (other than a registration effected
solely to implement an employee benefit plan, a transaction to which Rule 145 of
the Commission is applicable or any other form or type of registration in which
Registrable Securities cannot be included pursuant to Commission rule or
practice), it will give written notice to all holders of outstanding Registrable
Securities of its intention to do so. If such registration is proposed to be on
a form which permits inclusion of the Registrable Securities, upon the written
request of any holders of the Registrable Securities given within ten (10) days
after transmittal by Company to the holders of such notice, Company will,
subject to the limits contained in this Section 2.2, use its best efforts to
cause all such Registrable Securities of said requesting holders to be
registered under the Securities Act and qualified for sale under any state blue
sky law, all to the extent requisite to permit such sale or other disposition by
such holder of the Registrable Securities so registered; provided, that if the
underwriter managing such transaction notifies the holders of Registrable
Securities in writing that market or economic conditions limit the amount of
securities which may reasonably be expected to be sold on behalf of selling
stockholders, the number of Registrable Securities which are included in such
registration shall be reduced. Any reduction will first be imposed on holders
without registration rights and holders of registration rights other than the
holders of the Registrable Securities and to the extent that further reduction
is required, such reduction will be imposed pro rata among the holders of
Registrable Securities, based on their respective ownership of Registrable
Securities; provided that such underwriter may limit the Registrable Securities

                                      -3-
<PAGE>
 
sought to be registered by the holders of Registrable Securities on the
Company's registration statement to not less than thirty percent (30%) of the
total number of shares being registered.

     2.3  Registration Procedures.  If and whenever Company is required by the
          -----------------------
provisions of this Article 2 to use its best efforts to effect the registration
of any of its securities under the Securities Act, Company will, as
expeditiously as possible:

          (a) prepare and file with the Commission a registration statement with
respect to such securities and use its best efforts to cause such registration
statement to become and remain effective for a period not in excess of ninety
(90) days (or at the request of a majority of the selling holders, an additional
ninety (90) days);

          (b) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities covered by such registration statement
whenever the seller or sellers of such securities shall desire to sell or
otherwise dispose of the same, but only to the extent provided in this Article
2;

          (c) furnish to each seller such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as such seller may reasonably request
in order to facilitate the public sale or other disposition of the securities
owned by such seller;

          (d) use every reasonable effort to register or qualify the securities
covered by such registration statement under such other securities or state blue
sky laws of such jurisdictions as each seller shall reasonably request, and do
any and all other acts and things which may be necessary under such securities
or blue sky laws to enable such seller to consummate the public sale or other
disposition in such jurisdictions of the securities owned by such seller, except
that Company shall not for any such purpose be required to qualify to do
business as a foreign corporation in any jurisdiction wherein it is not so
qualified;

          (e) before filing the registration statement or prospectus or
amendments or supplements thereto, furnish to one counsel selected by the
holders of a majority of Registrable Securities included in such registration
copies of such documents proposed to be filed, which shall be subject to the
reasonable approval of such counsel; and

          (f) furnish to each prospective seller of more than fifty thousand
(50,000) shares of Registrable Securities a signed counterpart, addressed to the
prospective seller, of an opinion of counsel for Company, dated the effective
date of the registration statement, covering substantially the same matters with
respect to the registration statement (and the prospectus included therein) as
are customarily covered (at the time of such registration) in opinions of
Company's counsel delivered to the underwriters in underwritten public offerings
of securities.

                                      -4-
<PAGE>
 
     2.4 Expenses. All expenses incurred in effecting the registration provided
         --------
for in Section 2.1 and for all registrations provided for in Sections 2.2 and
2.10, including without limitation, all registration and filing fees, printing
expenses, fees and disbursements of counsel for Company and fees of one special
counsel of the selling holders of Registrable Securities selected by the holders
of a majority of the Registrable Securities included in the registration but
reasonably acceptable by Company both as to experience and to fees, underwriting
expenses (other than commissions or discounts), expenses of any audits of
Company's financial statements incident to or required by any such registration
and expenses of complying with the securities or blue sky laws of any
jurisdictions pursuant to Section 2.3(d) hereof (all of such expenses referred
to "Registration Expenses") shall be paid by Company, provided, that if an
offering pursuant to any registration commenced pursuant to Section 2.1(a) is
abandoned by the sellers (other than by reason of adverse information pertaining
to Company's business affairs or financial position, as opposed to stock market
conditions, unknown to the sellers and Company prior to the commencement of such
registration proceedings, in which event Company shall bear all Registration
Expenses), such sellers shall bear any costs incurred by Company in conjunction
with such registration or at their option forfeit their demand right under
Section 2.1.

     2.5  Indemnification.
          ---------------

          (a) Indemnification by Company. In the event of any registration of
any of its securities under the Securities Act pursuant to this Article, Company
shall indemnify and hold harmless each of the following parties ("Indemnified
Parties"):

              (i)   the seller of such securities;

              (ii)  each underwriter (as defined in the Securities Act);

              (iii) each other Person who participates in the offering of such
securities; and
              
              (iv)  each other Person, if any, who controls (within the meaning
of the Securities Act) such seller, underwriter or participating Person,

against any losses, claims, damages or liabilities, including any legal fees or
other cost or expense incurred for investigating or defending same (collectively
a "Liability"), joint or several, to which such Indemnified Party may become
subject under the Securities Act or any other statute or at common law, insofar
as such Liability (or action in respect thereof) arises out of or is based upon:

                    (a) any alleged untrue statement of any material fact
     contained in any registration statement under which such securities were
     registered under the Securities Act, any preliminary prospectus or final
     prospectus contained therein, or any amendment or supplement thereto, or

                                      -5-
<PAGE>
 
                    (b) any alleged omission to state therein a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading.

Notwithstanding the foregoing, Company shall not be liable to any Indemnified
Party in any such case to the extent that any such Liability arises out of or is
based upon any alleged untrue statements or alleged omission made in such
registration statement, preliminary or final prospectus, or amendment or
supplement thereto, in reliance upon and in conformity with information
furnished to Company by such Person specifically for use therein.  Moreover,
Company shall not be required to indemnify any Person against any Liability
arising from any untrue or misleading statement or omission contained in any
preliminary prospectus if such deficiency is corrected in the final prospectus
or for any liability which arises out of the failure of any such Person to
deliver a prospectus as required by the Securities Act.  The indemnity provided
for in this Section 2.5 shall remain in full force and effect regardless of any
investigation made by or on behalf of such Indemnified Party and shall survive
transfer of such securities by such seller.  Any legal fees or other costs and
expenses incurred by an Indemnified Party in connection with any liability
shall, subject to a good faith judgment of the Board of Directors of Company
that there is no reasonable basis for not indemnifying the Indemnified Party
pursuant to the requirements of this Agreement and the receipt of an acceptable
undertaking to reimburse the Indemnifying Party in the event that the
Indemnifying Party is not entitled to indemnification pursuant to the terms of
this Agreement, be reimbursed as incurred by Indemnified Party.

          (b) Indemnification by Holders of Registrable Securities.  Each holder
              ----------------------------------------------------
of any Registrable Securities shall, by acceptance thereof, indemnify and hold
harmless each other holder of any Registrable Securities, Company, its directors
and officers, each underwriter and each other Person, if any, who controls
Company or such underwriter or other holder ("Indemnitee") against any liability
(including fees and expenses incurred in investigating and defending same),
joint or several, to which Indemnitee may become subject under the Securities
Act or any other statute or at common law, insofar as such liability (or actions
in respect thereof) arises out of or is based upon:

              (i) the disposition by such holder of such Registrable Securities
in violation of the provisions of this Article;

              (ii) any alleged untrue statement of any material fact contained,
on the effective date thereof, in any registration statement under which
securities were registered under the Securities Act at the request of such
holder, any preliminary prospectus or final prospectus contained therein, or any
amendment or supplement thereto; or

              (iii) any alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading.

Such indemnification in the case of (ii) and (iii) applies to the extent, but
only to the extent, that such alleged untrue statement or alleged omission was
made in such registration state-

                                      -6-
<PAGE>
 
ment, preliminary or final prospectus, amendment or supplement thereto (A) in
reliance upon and in conformity with information furnished to Company by such
holder specifically for use therein, and (B) not based on the authority of an
expert as to which the holder had no reasonable ground to believe, and did not
believe, that the statements made on the authority of such expert were untrue or
that there was an omission to state a material fact. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
such Indemnitee and shall survive transfer of such securities by such holder.

          (c) Liability Exclusion for Holders.  No holder of Registrable
              -------------------------------
Securities shall be required to indemnify any Person against any liability
arising from any untrue or misleading statement or omission contained in any
preliminary prospectus if such deficiency is corrected in the final prospectus
or for any liability which arises out of the failure of any such Person to
deliver a prospectus as required by the Securities Act.  Moreover, the liability
of any holder of Registrable Securities pursuant to this Section 2.5 shall be
limited to an amount equal to the total public offering price, less underwriting
discounts and commissions, for the Registrable Securities sold by such holder
or, in the situation described in (i) of subsection (b), limited to an amount
equal to proceeds of the disposition referred to therein.

          (d) Contribution.  If the indemnification provided for in Section
              ------------
2.5(a) or 2.5(b) is unavailable or insufficient to hold harmless an Indemnified
Party in respect of any Liability, then the person required under such Section
2.5(a) or (b), as the case may be (the "Indemnifying Party"), shall contribute
to the amount paid or payable by such Indemnified Party as a result of such
Liability in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party on the one hand, and the Indemnified Party on the other,
in connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities, expenses or actions as well as any other relevant
equitable considerations, including the failure to give the notice required
hereunder.  The relative fault of the Indemnifying Party and the Indemnified
Party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact relates to information
supplied by the Indemnifying Party or the Indemnified Party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.  Company and the holders of Registrable
Securities agree that it would not be just and equitable if contributions
pursuant to this Section 2.5(d) were determined by pro rata allocation or by any
other method of allocation which did not take account of the equitable
considerations referred to above.   The amount paid or payable to an Indemnified
Party as a result of the Liabilities shall be deemed to include any legal or
other expenses reasonably incurred by such Indemnified Party in connection with
investigating or defending any such action or claim.  Notwithstanding the
contribution provisions of this Section 2.5(d), in no event shall the amount
contributed by any seller of Registrable Securities exceed the aggregate net
offering proceeds received by such seller from the sale of Registrable
Securities to which such contribution or indemnification claim relates.  No
person guilty of fraudulent misrepresentations (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who is not guilty of such fraudulent misrepresentation.

                                      -7-
<PAGE>
 
          (e) Further Indemnity.  Indemnification similar to that specified in
              -----------------
paragraphs (a) through (d) of this Section shall be given by Company and each
holder of any Registrable Securities (with such modifications as may be
appropriate) with respect to any required registration or other qualification of
the Registrable Securities under any federal or state law or regulation of
governmental authority other than the Securities Act.

          (f) Procedures, Rights to Separate Counsel.  In the event an
              --------------------------------------
Indemnified Party or Indemnitee ("Claimant") receives a complaint, claim or
other notice of any loss, claim or damage, liability or action giving rise to a
claim for indemnification under this Section, the Claimant shall promptly notify
the Indemnifying Party of such complaint, notice, claim or action, and such
Indemnifying Party shall have the right to investigate and defend any such loss,
claim, damage, liability or action.  The Claimant shall have the right to employ
separate counsel in any such action and to participate in the defense thereof,
but the fees and expenses of such counsel shall not be at the expense of the
Indemnifying Party unless the Indemnifying Party fails to promptly defend, in
which case the fees and expenses of such separate counsel shall be borne by the
Indemnifying Party, provided, however, that a Claimant shall have the right to
retain its own counsel, with the fees and expenses to be paid by the
Indemnifying Party, if the representation of such Claimant would be
inappropriate due to actual or potential differing interests between the
Claimant and the other party represented by such counsel in such proceeding.  In
no event shall an Indemnifying Party be obligated to indemnify any Person for
any settlement of any claim or action effected without the Indemnifying Party's
prior written consent.

     2.6  Termination of Registration.  Notwithstanding the foregoing provisions
          ---------------------------
of this Article 2, the rights to registration and the designation of Registrable
Securities shall terminate as to any particular securities when such securities
shall have been lawfully sold by the holder to the public thereof pursuant to a
registration statement or Rule 144 and as to all Registrable Securities on the
earlier of seven (7) years from the date hereof or December 12, 2000.

     2.7  Compliance with Rule 144.  At the request of any holder of Registrable
          ------------------------
Securities who proposes to sell the Registrable Securities in compliance with
Rule 144 of the Commission, Company shall forthwith furnish to such holder or
holders a written statement of compliance with the filing requirements of the
Commission as set forth in such Rule, as such Rule may be amended from time to
time and make available to the public and such holders such information as will
enable the holders to make sales of Registrable Securities pursuant to Rule 144.

     2.8  Consent to be Bound.  Each subsequent holder of Registrable Securities
          -------------------
must consent in writing to be bound by the terms and conditions of this Article
2 in order to acquire the rights granted pursuant to Article 2 and shall be
required to execute such customary underwriting agreements as may be proposed by
the managing underwriter.

     2.9  Amendments.  The provisions of this Agreement may be amended, and
          ----------
Company may take any action herein prohibited or omit to perform any act herein
required to

                                      -8-
<PAGE>
 
be performed by it, only if Company has obtained the written consent of the
holders of at least two thirds (2/3) of the Registrable Securities.

     2.10 Form S-3.  As of December 20, 1996, the Company is, and it shall use
          --------
its best efforts to remain, qualified for registration on Form S-3.  The holders
of the Registrable Securities shall have the right to request unlimited
registrations on Form S-3 (such requests shall be in writing and shall state the
number of shares of Registrable Securities to be disposed of and the intended
method of disposition of such shares by such holder or holders).  Company shall
not be required to effect a registration pursuant to this Section 2.10 if, in
the good faith judgment of Company, such registration will hinder or interfere
with a concurrent or proposed security issuance of, or acquisition by, Company
or if the holder or holders requesting registration propose to dispose of shares
of the Registrable Securities having an aggregate disposition price (before
deduction of underwriting discounts and expenses of sale) of less than Five
Hundred Thousand Dollars ($500,000).  This Section shall not be interpreted to
restrict Company from acquiring its own shares or to require Company to sell its
own shares.  Company shall give notice to all holders of the Registrable
Securities of the receipt of a request for registration pursuant to this Section
2.10 and shall provide a reasonable opportunity for other holders to participate
in the registration.  Subject to the foregoing, Company will use its best
efforts, in each case, to effect promptly the registration of all shares of the
Registrable Securities on Form S-3 to the extent requested by the holder or
holders thereof for purposes of disposition.

     2.11 Assignability of Registration.  Subject to Section 2.8 hereof, the
          -----------------------------
registration rights set forth in this Article 2 are assignable to each assignee
of Registrable Securities conveyed in accordance herewith (i) who agrees in
writing to be bound by the terms and conditions of this Agreement and (ii) who
after such transfer owns at least fifty thousand (50,000) shares of Registrable
Securities or is an affiliate of such transferror or is a Purchaser.

     2.12 Designation of Underwriter.  In the case of any registration effected
          --------------------------
pursuant to this Article 2, Company shall have the right to designate the
managing underwriter, subject to the approval of Purchasers, which approval will
not be unreasonably withheld.

     2.13 Rights Which May Be Granted to Subsequent Investors.  Company may not
          ---------------------------------------------------
grant any registration rights to third parties which are senior to or on a
parity with those granted to Purchasers pursuant to this Agreement without
consent of two thirds (2/3) of the shares of Registrable Securities held by
Purchasers.

     2.14 Information by Seller.  The holder or holders of Registrable
          ---------------------
Securities included in any registration shall furnish to Company such
information regarding such holder or holders, the Registrable Securities held by
them and the distribution proposed by such holder or holder as Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Article.

                                      -9-
<PAGE>
 
     2.15 Standstill.  As consideration for Company's agreeing to its
          ----------
obligations under this Article 2, in connection with any registration of the
Common Stock of Company, each holder of Registrable Securities does hereby, upon
the request of the underwriters managing any underwritten offering of Company's
securities, agree not to sell or otherwise dispose of any Registrable Securities
(other than those included in the registration) without the prior written
consent of Company or such underwriters, as the case may be, for such period of
time (not to exceed one hundred eighty (180) days) from the effective date of
such registration as the Company and underwriters may specify.  Such agreement
is conditioned upon each executive officer, director and holder of three percent
(3%) or more of Company's Common Stock (on a fully diluted basis) entering into
a like agreement.

     2.16 Restrictions on Transfer.
          ------------------------

          (a) Unless and until otherwise permitted by this Agreement, each
certificate for the securities issued to a Purchaser (the "Securities") or to
any subsequent transferee of any such certificate shall be stamped or otherwise
imprinted with a legend in substantially the following form:

     "The shares represented by this certificate have been acquired for
     investment and have not been registered under the Securities Act of 1933.
     Such shares may not be sold or transferred in the absence of such
     registration or unless the Company receives an opinion of counsel or other
     evidence reasonably acceptable to it stating that such sale or transfer is
     exempt from the registration requirements of said act.  Copies of the
     agreement covering the purchase of these shares and restricting their
     transfer may be obtained from the secretary of the Company."

          (b) Prior to any transfer or attempted transfer of any Securities
bearing the legend set forth in paragraph (a) of this Section, the holder
thereof shall give Company written notice of its intention to transfer.  If, in
the written opinion of counsel for the holder, accompanying such notice and in
form and substance satisfactory to Company and its counsel, addressed to Company
and the holder, the proposed transfer may be effected without registration of
such security, the securities proposed to be transferred may be transferred in
accordance with the terms of said notice and in compliance with applicable state
securities laws and regulations.  Company shall not be required to effect any
such transfer prior to the receipt of such favorable opinion or opinions;
provided that, if the proposed transfer is governed by Rule 144 promulgated by
the Commission, or any successor rule, such opinion shall not be required, but
Company may prevent such transfer until it receives evidence satisfactory to it
and its counsel that the transfer complies with Rule 144.  Each transfer shall
comply with all applicable Commissioner's rules and applicable state securities
laws.  Each certificate evidencing securities transferred as above provided
shall bear the restrictive legend set forth in paragraph (a) of this Section
2.16, unless the transfer is made pursuant to Rule 144 or the opinion of counsel
referred to above is to the further effect that such legend is not required in
order to establish compliance with the Securities Act.  Upon the removal of

                                      -10-
<PAGE>
 
the restrictive legend, all obligations of a holder pursuant to this Section
2.16 shall immediately terminate.

          (c) The proposed transfer of such securities may not be effected
without registration thereof under the Securities Act, such holder shall not
consummate the proposed transfer.  Company may order its transfer agents to stop
the transfer of any Securities bearing the legend required by this Section until
the conditions herein with respect to transfer of such securities have been
satisfied.

3.   COVENANTS OF COMPANY.

     3.1  Financial Statements and Other Information.
          ------------------------------------------

copies of all financial statements, proxy statements and reports that Company
sends to its stockholders, and copies of all registration statements and all

directors file with the Commission or with any securities exchange on which any
of its securities are then listed, and copies of all press releases and other
statements made available generally by Company to the public concerning material
developments in Company's business.  The right to receive materials under this
Section shall not be transferable unless the transferee and any affiliates after
such transfer own at least fifty thousand (50,000) shares of Registrable
Securities.

4.   MISCELLANEOUS.

     4.1  Consent to Amendments.  Except as otherwise expressly provided herein
          ---------------------

the written consent of holders of at least two thirds (2/3) of the Registrable
Securities.  No course of dealing between Company and the holder of any security
issued pursuant to this Agreement or any delay in exercising any rights
hereunder will operate as a waiver of any rights of any such holders.

     4.2  Successors and Assigns.  Except as otherwise expressly provided
          ------------------------
herein, all covenants and agreements contained in this Agreement by or on behalf
of any of the parties hereto will bind and inure to the benefit of the
respective successors and assigns of the parties hereto whether so expressed or

extent of such prohibition or invalidity, without invalidating the remainder of
this Agreement.

in that action or proceeding, in addition to any other relief to which it or
they may be entitled.

     4.10 Remedies.  Any Person having any rights under any provision of this
          --------
Agreement will be entitled to enforce such rights specifically, to recover
damages by reason of any breach of any provision of this Agreement, and to
exercise all other rights granted by law, which rights may be exercised
cumulatively and not alternatively.  Moreover, the parties

                                      -12-

acknowledge that each party's obligation under this Agreement is unique. If any
party should default in its obligations under this Agreement, the parties each
acknowledge that it would be extremely impracticable to measure the resulting
damages; accordingly, the nondefaulting party, in addition to any other
available rights or remedies, may sue in equity for specific performance and the
parties each expressly waive the defense that a remedy in damages will be
adequate.

     4.11 Final Agreement.  This Agreement constitutes the final agreement of
          ---------------
the parties concerning the matters herein, and supersedes all prior and
contemporaneous agreements and understandings (including, but not limited to,
the Prior Agreement, which shall be of no further force or effect).

                                      -13-

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
December 31, 1996.

            METATOOLS, INC. ACQUIRES REAL TIME GEOMETRY CORPORATION
          -Real Time 3D Enabling Technologies Increase MetaTools Reach
                        into Computer Graphics Markets-
                                        
Carpinteria, Calif., December 23, 1996 --  MetaTools, Inc. (Nasdaq:  MTLS), the
visual computing software company, announced today a definitive agreement to
acquire Real Time Geometry Corporation ("RTG"), a privately held company based
in Princeton, New Jersey, specializing in real time 3D graphics and
visualization technologies.   The acquisition of RTG expands MetaTools ability
to participate in the rapid expansion of broad application areas that will
utilize 3D technology.  The RTG technologies are being developed for
applications on Windows, Macintosh, SGI, Sun, Nintendo, Sega and Sony
PlayStation platforms.

TRANSACTION DETAILS
- -------------------

  MetaTools plans to issue 1,360,000 shares of MetaTools common stock in
exchange for all the outstanding shares of RTG.  MetaTools will also issue
approximately 800,000 Nonqualified stock options to purchase MetaTools common
stock to current RTG employees.  The majority of the options to be issued in the
transaction will have an exercise price equal to the fair market value of the
MetaTools common stock on the issuance date and will vest over three to four
years.  The remaining options for approximately 100,000 shares of MetaTools
common stock will have an average exercise price of $4.69 per share.

  The acquisition, which is expected to close by December 31, 1996, will be
accounted for by the purchase method of accounting by MetaTools.  If the common
stock of MetaTools on the closing date is $14.50 per share (the closing price on
December 20, 1996) then MetaTools would expect to charge approximately $17
million against earnings during the fourth quarter ended December 31, 1996
related to the write-off of research and development in-process at RTG and other
costs related to the transaction.

3D ENABLING AND APPLICATION TECHNOLOGY
- --------------------------------------

  The addition of RTG's core innovations and development capabilities in real
time 3D graphics accelerate MetaTools strategic expansion in the rapidly
emerging consumer, prosumer and professional markets for 3D tools, applications
and titles.  Key innovations of RTG's real time 3D technology include:  1)
decreasing the time required to create, render and display 3D images and
environments; 2) enabling the creation of dynamic, real time resolution changes
to 3D models; 3) improving the visual resolution and navigation of 3D graphics.
RTG's 3D graphics innovations, combined with MetaTools design and application
development expertise, will allow the RTG technology to be incorporated into
MetaTools existing and planned professional tools and consumer creative
entertainment software products.  The company also anticipates strategic
licensing agreements with third party hardware and software companies, including
developers of 3D acceleration chips, still and motion imaging, animation and
video graphics products, computer and console games, architectural and
engineering design products, financial visualization and medical applications
software.

INCORPORATION OF RTG'S ENGINEERING TEAM WITH METATOOLS R&D
- ----------------------------------------------------------

  Real Time Geometry's existing operations of 23 people, including 20 research
employees, will remain in Princeton, New Jersey as the MetaTools' Real Time
Geometry research and development lab.  Alexander "Sasha" Migdal and Robert Rice
will continue to lead the development of Real Time Geometry's 3D imaging
technologies.   Through the acquisition of RTG, Sasha Migdal will assume the
role of vice president & chief scientist and Robert Rice will become vice
president of business development.
