        3.4 FORM OF USER LICENSE

        If and to the extent that the parties agree it is practicable, use by an
        end user of ECential will require a license key. To obtain a license key
        for ECential, registration is required by the registered user of the
        product or by Caldera's Reseller. Registration is accomplished by the
        end user or Caldera's Reseller accessing a web registration page hosted
        by Evergreen and/or Caldera and filling in the required registration
        information. Upon completion of the registration process, the registered
        user will obtain (or the Reseller will obtain for its end user customer)
        the license key and a User License for the ECential software product
        being registered. The User License shall be the Software License
        Agreement of Attachment B. If obtained by either parties Reseller, then
        it will be passed on to the end user. Evergreen will provide Caldera
        with the information requested by Caldera to create and maintain the
        Caldera web page. Caldera will reciprocate.

        If this registration process is not utilized or if it does not include a
        procedure acceptable to Evergreen by which the end user accepts the
        Software License Agreement, then Caldera has the following obligation:
        The ECential licenses from Evergreen that Caldera is authorized to sell
        under Section 3.1 above shall be sold on behalf of Evergreen under this
        Agreement and are to include the Software License Agreement attached as
        Exhibit B to this Agreement. Caldera shall include a copy of the
        applicable Software License Agreement with each license of ECential that
        Caldera sells. If Caldera believes that it is not practicable to obtain
        written signatures for the Software License Agreement, then Evergreen
        shall incorporate into the Software License Agreement and the ECential
        Code terms and procedures that provide for acceptance of the Software
        License Agreement by the end user by installing or using ECential.
        Caldera shall not interfere with such contract acceptance terms and
        procedures.

        The Software License Agreement shall govern the use of ECential by end
        user customers. The Software License Agreement includes a grant by
        Evergreen to the end user to use ECential (including the third party
        software of Sections 3.3 and 3.4). The Software License Agreement is an
        agreement between Evergreen and the end user. Caldera is not a party to
        the Software License Agreement and has no obligation or liability
        thereunder.

        or delay approval.

4. FEES

        4.1 INITIAL PAYMENT

        Caldera and Evergreen will pay each other a license fee of $100,000 in
        each of the first two quarters after the agreement is signed. The first
        payment will be made within ten days of the execution of this agreement.
        The second payment will be made with the second quarterly report. This
        Agreement shall become effective only upon the investment in Evergreen
        by Caldera and the stock exchange referred to in the Master Agreement

        4.2 ROYALTY

        The "Selling Party" shall mean the party who sells, distributes and/or
        licenses a copy of eBuilder or Evergreen's version of the bundled
        product directly to an end user or to a Reseller. The other party is the
        "Other Party." "Proceeds" shall mean the gross revenue received by the
        Selling Party from an end user or a Reseller, whichever is applicable,
        for the sale, distribution and/or licensing of eBuilder or Evergreen's
        version of the bundled product.

        "Third Party Software Payments" shall mean payments to third parties for
        Third Party Software in eBuilder or Evergreen's version of the bundled
        product.

        From the Proceeds, all payments payable for applicable Third Party
        Software shall be made. If Caldera is the Selling Party, then Caldera
        shall pay such payments for OpenLinux Third Party Software directly to
        the applicable third parties and shall pay such payments for ECential
        Third Party Software to Evergreen, and Evergreen shall pass such payment
        on to the applicable third parties. If Evergreen is the Selling Party,
        then Evergreen shall pay such payments for ECential Third Party

        Software directly to the applicable third parties and shall pay such
        payments for OpenLinux Third Party Software to Caldera, and Caldera
        shall pass such payment on to the applicable third parties.

        Proceeds do not include fees or payments for any support, maintenance or
        services not included in the price for eBuilder. For example, support,
        maintenance and other services invoiced or charged separate from the
        price for the sale, distribution and/or licensing of eBuilder or
        Evergreen's version of the bundled product, are not subject to the
        Royalty. Software products which are distributed or licensed in
        conjunction with eBuilder, but not included by either party in eBuilder
        or Evergreen's version of the bundled product, shall not be subject to
        the Royalty, i.e., the Royalty is not payable on the sales price
        received by the Selling Party for such other software products.

        "Net Proceeds" shall mean Proceeds minus Third Party Software Payments.

        "Net Revenue" shall mean 50% of Net Proceeds.

        [****] of Net Revenue [****].

        The parties agree that they will review on a quarterly basis by the last
        day of March, June, September, and December of each calendar year, the
        definition and percentages of net revenue.

        Evergreen may have customers who choose to deploy eCential on Linux
        distributions that compete with Caldera. Evergreen will promote the
        eBuilder bundle or Evergreen's version of the bundled product to
        customers who ask for Linux. If the customer insists on purchasing
        eCential and not the bundle Evergreen may sell it to them. If Evergreen
        knows at the time of any transaction that eCential will be deployed on
        Linux then that sale is subject to the royalty payments described above.

        Evergreen may choose to refer customers who seek a Linux Support
        Agreement to Caldera. If Caldera signs an agreement with a customer
        referred by Evergreen then Caldera will give Evergreen [****] of the
        first 12 months revenue as a referral fee.

        Caldera may choose to refer customers who seek support on eCential to
        Evergreen. If Evergreen signs an agreement with a customer referred by
        Caldera then Evergreen will give Caldera [****] of the first 12 months
        revenue as a referral fee.

        4.3 PAYMENT

        Selling Party will make quarterly payments to Other Party of the royalty
        amounts Other Party is entitled to receive hereunder. Payments will
        accompany the quarterly reports described in section 3.5. Reports and
        payments are due the 20th day of that month which follows the end of
        each calendar quarter. To compensate for the loss of the use of money
        and the administrative expense involved in collecting past due amounts,
        all amounts past due or in default under this Agreement shall bear
        interest at a rate of one (1.5%) per month.

        4.4 TAXES AND OTHER FEES.

        As between Selling Party and Other Party, Selling Party shall be
        responsible for payment of all sales, use and other taxes, fees and/or
        assessments of any sort which come due because of or are related to
        transactions between Selling Party and its customers. Selling Party
        shall also pay, at its own expense, all import and export licenses and
        permits, customs charges, and duty fees required to

                                       9

        However, all of the foregoing are not including in Proceeds. Nothing
        herein applies to Other Parties income taxes.

        4.5 INSPECTION OF SELLING PARTY RECORDS.

        Upon twenty (20) days written notice to Selling Party, at Other Parties
        expense (except as otherwise provided below), and no more often than
        once per year, Other Parties designated representative, or its
        independent certified public accountant shall have the right to inspect
        Selling Parties records relevant to the royalty or selling parties
        compliance with the alliance during business hours solely for the
        purposes of verifying the royalty amounts due to Other Party and Selling
        Parties compliance with the provisions of this License and all related
        Contracts under the Master Agreement. A final inspection shall occur no
        later than one year after the termination of this Agreement. Selling
        Party shall make immediate payment of any amounts that an inspection
        accurately shows to be due to Other Party. If, as a result of any such
        inspection, it is accurately determined that the amount paid or due from
        Selling Party to Other Party for the period being reviewed has been
        understated by an amount in excess of five percent (5%) of the total
        amount due Other Party, then Selling Party shall promptly pay the
        reasonable cost of such inspection. Other Parties representative or
        independent certified public accountant must agree in writing with
        Selling Party to keep confidential Selling Parties records and the
        contents thereof, except for reasonable disclosures to Other Party
        relating to Selling Parties failure to pay the royalty and/or Selling
        Parties failure to comply with its obligations under any of the
        contracts to the Business Alliance. Other Party must keep such
        disclosures confidential and not use for any purpose, except as
        necessary to enforce Selling Parties royalty obligation or any terms of
        the contracts of the Business Alliance.

        misappropriated trade secret, or violate any privacy or other rights of
        any third party and (b) Evergreen has full right, power, and authority
        to enter into this Agreement and to carry out its obligations hereunder.

                1. Date data representative of years are represented or stored
                   in a four digit format, i.e., full representation of the year
                   (e.g., "1998") rather than partial representation of the year
                   (e.g., "98").

                2. The screen displays, reports and printed output generated by

                3. The Evergreen Software will not include any two digit
                   representation of years that causes: (a) execution of the
                   Evergreen Software to terminate abnormally, (b) invalid
                   values or incorrect results in century date data, (c)

                   multi-century date values.

                5. The calculations performed by the Evergreen Software will
                   accurately accommodate the occurrence of leap years.

        Software provided by Evergreen under this Agreement, except for

                Evergreen Software on Caldera's or its Affiliate's computer
                system (e.g., remote access via modem) solely for purposes of
                providing maintenance or technical support to Caldera or its
                Affiliate, provided that such code or hardware component is
                first disclosed to Caldera and approved by Caldera in writing.

                "Unauthorized Code" means any virus, Trojan horse, worm, or

        EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES SET FORTH IN THE BUSINESS
        ALLIANCE, THE EVERGREEN SOFTWARE IS OFFERED "AS IS" WITH ALL FAULTS.
        CALDERA MAKES NO WARRANTIES NOT EXPRESSLY SET FORTH IN THE BUSINESS
        ALLIANCE. ALL WARRANTIES AND OTHER TERMS WHICH WOULD OTHERWISE BE
        IMPLIED OR INCORPORATED INTO THIS AGREEMENT BY STATUTE OR COMMON LAW ARE
        HEREBY EXCLUDED BY THE PARTIES. THE WARRANTIES OF MERCHANTABILITY AND
        FITNESS FOR A PARTICULAR PURPOSE ARE SPECIFICALLY DISCLAIMED BY
        EVERGREEN AND CALDERA. IT IS EXPRESSLY AGREED THAT EVERGREEN SHALL NOT
        BE IN ANY WAY RESPONSIBLE FOR THE COMMERCIAL SUCCESS OF THE EVERGREEN
        SOFTWARE OR THE BUNDLED SOFTWARE AND THAT CALDERA SHALL NOT BE IN ANY
        WAY RESPONSIBLE FOR THE COMMERCIAL SUCCESS OF CALDERA SOFTWARE OR

        8.4 RESPONSE TO ANY INFRINGEMENT CLAIM.

        If Caldera receives notice of any claim that the Evergreen Software
        infringes a United States or foreign patent or copyright, Caldera shall
        promptly give written notice of the claim to Evergreen in accordance
        with Section 9.2 below. If Evergreen determines that the claim may have
        merit, Evergreen may instruct Caldera to cease selling licenses for the
        Evergreen Software. Evergreen shall have no obligation to indemnify
        Caldera for any sales of licenses that occur (a) after Caldera has
        notice of the infringement claim but before notice of such claim is
        given to Evergreen, or (b) after Evergreen has instructed Caldera to
        cease selling licenses, except for sales that are required by
        contractual commitments existing prior to (a) and (b) above. Upon
        receiving notice of the claim and determining that the claim may have
        merit, Evergreen shall use commercially reasonable efforts to (a)
        procure the right to continue using the Evergreen Software or portions
        thereof and all rights and licenses necessary for this Agreement and the
        Business Alliance; or (b) modify or replace all or part of the concerned
        Evergreen Software to avoid any infringement, provided that the modified
        Evergreen Software or the replacement is substantially the same or
        better in functions, features and performance. If Evergreen determines
        that it is not able to do either of the foregoing in a commercially
        reasonable fashion, as determined by Evergreen in Evergreen's sole
        discretion, Evergreen may terminate Caldera's license to sell further
        licenses of the Evergreen Software (i.e., remove the infringing
        Evergreen Software from eBuilder. In such case, Caldera shall have the
        right to terminate all future obligations of the parties under the
        Business Alliance, including this Agreement.

        If Evergreen receives notice of any claim that the Caldera Software
        infringes a United States or foreign patent or copyright, Evergreen
        shall promptly give written notice of the claim to Caldera in accordance
        with Section 9.2 below. If Caldera determines that the claim may have
        merit, Caldera may instruct Evergreen to cease selling licenses for the
        Caldera Software. Caldera shall have no obligation to indemnify
        Evergreen for any sales of licenses that occur (a) after Evergreen has
        notice of the infringement claim but before notice of such claim is
        given to Caldera, or (b) after Caldera has instructed Evergreen to cease
        selling licenses, except for sales that are required by contractual
        commitments existing prior to (a) and (b) above. Upon receiving notice
        of the claim and determining that the claim may have merit, Caldera
        shall use commercially reasonable efforts to (a) procure the right to
        continue using the Caldera Software or portions thereof and all rights
        and licenses necessary for this Agreement and the Business Alliance; or
        (b) modify or replace all or part of the concerned Caldera Software to
        avoid any infringement, provided that the modified Caldera Software or
        the replacement is substantially the same or better in functions,
        features and performance. If Caldera determines that it is not able to
        do either of the foregoing in a commercially reasonable fashion, as


                                       16
<PAGE>   17

        determined by Caldera in Caldera's sole discretion, Caldera may
        terminate Evergreen's license to sell further licenses of the Caldera
        Software (i.e., remove the infringing Caldera Software from eBuilder).
        In such case, Evergreen shall have the right to terminate all future
        obligations of the parties under the Business Alliance, including this
        Agreement.

9. CROSS INDEMNITY

        9.1 INDEMNIFICATION

        Each party (the "first party") hereby agrees to indemnify, defend and
        hold the other party harmless from and against any and all losses,
        damages, judgments, settlements, liabilities, costs, charges and
        expenses, including reasonable attorneys' fees, arising out of or from
        any infringement or claim of infringement of any patent, copyright,
        trade secret, trademark or other proprietary right. When the
        infringement or claim of infringement applies to Evergreen Software,
        then Evergreen is the "first party." When the infringement or claim of
        infringement applies to Caldera Software, then Caldera is the "first
        party." The exclusions of Section 8.2 or elsewhere shall also be
        exclusions from the first parties obligations to indemnify, defend and
        hold harmless the other party hereunder. Regarding the part of said
        indemnity running from first party in favor of the other party, the
        first party shall indemnify, defend and hold harmless the other party
        only if: (i) the infringement is not caused by the combination of the
        Software (Evergreen Software if Evergreen is the first party; and
        Caldera Software if Caldera is the first party) with any other item not
        provided by the first party, including but not limited to software,
        data, or hardware, (ii) notification by the indemnified party shall be
        in accordance with Section 9.2 below. and (iii) the indemnified party
        allows the indemnifying party to control any litigation and settlement
        of such infringement charges in accordance with Sections 9.3 and 9.4
        below. Should any portion of the Software (Evergreen Software if
        Evergreen is the first party; and Caldera Software if Caldera is the
        first party) or its intended use become, or in the first parties opinion
        be likely to become, the subject of a claim of infringement of a United
        States patent, copyright or other proprietary right, then Section 8.4
        above shall apply. The first parties liability and obligation to the
        other party in the event of infringement or claimed infringement shall
        be strictly limited to the obligations set forth in this Article 9.

        9.2 NOTICE OF CLAIMS.

        A party entitled to indemnification under Section 9.1, or any other
        provision of this Agreement (an "Indemnified Party") shall give the
        party required to provide such indemnification (the "Indemnifying
        Party") written notice of any claim for indemnification promptly after
        the Indemnified Party actually learns of the existence of such claim.
        The Indemnifying Party shall have no obligation with respect to any
        claim to the extent that failure to promptly give such notice materially
        prejudices the ability of the Indemnifying Party to defend such claim.

        9.3 CONDUCT OF DEFENSE.

        The Indemnified Party shall permit the Indemnifying Party to assume the
        defense of any claim covered by the indemnification. The Indemnified
        Party shall have the right to approve the counsel who shall conduct the
        defense of the claim but shall not withhold such approval unreasonably.
        The Indemnified Party may participate in the defense at the Indemnified
        Parties expense.

        9.4 SETTLEMENTS.

        No Indemnifying Party, in the defense of any claim, shall, except with
        the consent of each Indemnified Party, consent to entry of any judgment
        or enter into any settlement that does not include an unconditional
        release by the claimant of the Indemnified Party from all liability in
        respect to the


                                       17
<PAGE>   18

        claim. The Indemnified Party shall not settle any Claim without the
        consent of the Indemnifying Party. The consent of the Indemnifying Party
        is a condition to the obligation of the Indemnifying Party to pay money
        pursuant to this Article 9. The Indemnifying Party shall not
        unreasonably withhold consent to any proposed settlement. The settlement
        must not include any obligation on the part of the Indemnified Party,
        i.e., the settlement must be satisfied by the Indemnifying Party in
        full.

10. LIMITATION OF LIABILITY

        10.1 EXTENT OF LIABILITY.

        Except for liabilities and obligations under Section 8.4 or Article 9,
        and the royalty fees due Caldera pursuant to this Agreement and any
        interest thereon, Evergreen's liability arising out of this Agreement or
        arising out of the use or distribution of the Evergreen Software by
        Caldera shall be limited to the amount paid by Caldera to Evergreen for
        the Evergreen Software. Except for liabilities and obligations under
        Section 8.4 and Article 9, and the royalty fees due Evergreen pursuant
        to this Agreement and any interest thereon, Caldera's aggregate
        liability to Evergreen shall not exceed a limit equal to the same
        amount. Notwithstanding the foregoing, the limitation of liability under
        this section 10.1, does not apply to liabilities that arise to either
        party as a result of actions that infringe intellectual property or
        violate Confidential Information responsibilities under this Agreement.

        10.2 DISCLAIMER.

        IN NO EVENT SHALL EVERGREEN OR CALDERA BE LIABLE FOR COSTS OF
        PROCUREMENT OF SUBSTITUTE GOODS BY ANYONE (OTHER THAN AS PROVIDED FOR IN
        SECTIONS 8.4 AND 9.1), NOR WILL EVERGREEN OR CALDERA BE LIABLE FOR ANY
        SPECIAL, INDIRECT, INCIDENTAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL
        DAMAGES, INCLUDING WITHOUT LIMITATION LOST PROFITS, RELATING TO THIS
        AGREEMENT OR RESULTING FROM A USE OR INABILITY TO USE THE EVERGREEN
        SOFTWARE OR CALDERA SOFTWARE, OR EBUILDER OR OPENLINUX FOR EBUILDER,
        HOWEVER CAUSED, ARISING UNDER ANY CAUSE OF ACTION, INCLUDING WITHOUT
        LIMITATION, BREACH OF CONTRACT, WARRANTY, STRICT LIABILITY, NEGLIGENCE
        OR OTHERWISE, AND WHETHER OR NOT EVERGREEN OR CALDERA HAS BEEN ADVISED
        OF THE POSSIBILITY OF SUCH DAMAGES. THE ESSENTIAL PURPOSE OF THIS
        SECTION 10.2 IS TO LIMIT THE POTENTIAL LIABILITY OF EVERGREEN AND
        CALDERA ARISING OUT OF THIS AGREEMENT. Notwithstanding the foregoing,
        the limitation of liability under this section 10.2, does not apply to
        liabilities that arise to either party as a result of actions that
        infringe intellectual property or violate Confidential Information
        responsibilities under this Agreement.

11. CONFIDENTIALITY.

        Evergreen and Caldera agree that each of them shall, during the term of
        this Agreement and for so long thereafter as the information remains
        confidential, take all steps which are reasonable to safeguard the
        confidentiality of, and proprietary rights to, the confidential
        information ("Confidential Information") of the other party which may be
        disclosed under this Agreement (including, but not limited to, product
        plans, designs, business plans, technical specifications, research, and
        customer or financial data, and Proprietary Data) and shall not, without
        the prior written consent of the other party, (a) use such Confidential
        Information for its own benefit or the benefit of any third party except
        for purposes expressly provided for in this Agreement, or (b) disclose
        such Confidential Information to any third party. This Article 11 shall
        not be construed to restrict, and Confidential Information shall not
        include, information which (a) is publicly known at the time of its
        disclosure to the receiving party, (b) is lawfully received by a party
        from a third party not bound in a confidential relationship to the
        disclosing party, (c) was already known by the receiving party prior to
        disclosure by the disclosing party, or (d) is independently developed or
        created by the receiving party without use of the Confidential
        Information from the disclosing party. There is no restriction on
        disclosures required by

                                       18
<PAGE>   19


        law or court order. If, however, either party is issued a Subpoena or
        court order requiring disclosure of confidential information, it shall
        provide the other party hereto notice of such Subpoena or notice and
        provide said party an opportunity to contest it. Confidential
        Information which becomes publicly known through no fault of the
        receiving party after disclosure to the receiving party shall cease to
        be Confidential Information.

12. RESTRICTED RIGHTS OF GOVERNMENT USERS

        If an end user of any Evergreen Software will be an agency, department,
        or other entity of the United States Government (the "Government"), the
        end user's Software License Agreement shall include such "restricted
        rights of government users" clause as Evergreen has included in Exhibit
        B.

IN WITNESS WHEREOF the parties through their duly authorized representatives
have caused this OEM License Agreement to be executed as of the date first set
forth above.

        WRITTEN MATERIALS ARE PROVIDED "AS IS" WITHOUT EXPRESS OR IMPLIED
        WARRANTY OF ANY KIND. EVERGREEN FURTHER DISCLAIMS ALL IMPLIED
        WARRANTIES, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF
        MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. EVERGREEN DOES NOT
        WARRANT THAT THE SOFTWARE WILL BE ERROR FREE OR WILL OPERATE WITHOUT
        INTERRUPTION OR THAT THE SOFTWARE DOES NOT INFRINGE ANY COPYRIGHT,
        PATENT, ETC. OF ANY THIRD PARTY. THE ENTIRE RISK ARISING OUT OF THE USE
        OR PERFORMANCE OF THE SOFTWARE AND ACCOMPANYING WRITTEN MATERIALS
        REMAINS WITH LICENSEE.

        The Software is not designed or licensed for use in hazardous
        environments requiring fail-safe controls, including without limitation
        operation of nuclear facilities, aircraft navigation or communication
        systems, air traffic control, and life support or weapons systems.
        Without limiting the generality of the foregoing, Evergreen specifically
        disclaims any express or implied warranty of fitness for such purposes.

9.  INDEMNITY. Both parties shall indemnify, defend and hold the other party
    harmless from and against any and all losses, damages, liabilities, costs,
    charges and expenses, including reasonable attorneys' fees, arising out of
    any breach by either party of their obligations under this agreement or from
    any infringement or claim of infringement of any patent, copyright, trade
    secret, trademark or other proprietary right based on or arising out of the
    creation, use or installation by Licensee of the Software. Regarding the
    part of said indemnity running from Evergreen in favor of Licensee,
    Evergreen shall indemnify and hold harmless Licensee for any liability for
    infringement of any United States patent, copyright or trade secret rights
    of and due to a third party caused solely by the use of the Software in
    accordance with the Software's documentation, provided that: (i) the
    infringement is not caused by the combination of the Software with any other
    item not provided by the Evergreen, including but not limited to software,
    data, or

    of Licensee's first knowledge of a charge of infringement of patent,
    copyright or trade secret rights by another party, and (iii) Licensee agrees
    to allow Evergreen to fully control any litigation and settlement of such
    infringement charges provided any such settlement does not require the
    Licensee to make any payment.

10. NO CONSEQUENTIAL DAMAGES. Evergreen shall not be liable to Licensee for
    indirect, special, incidental, exemplary, punitive, or consequential damages
    (including, without limitation, lost profits) related to this Agreement or
    resulting from Licensee's use or inability to use the Software, arising from
    any cause of action whatsoever, including without limitation, contract,
    warranty, strict liability, or negligence, even if notified of the
    possibility of such damages.

11. LIMITATION ON RECOVERY. UNDER NO CIRCUMSTANCES, INCLUDING NEGLIGENCE, SHALL
    EVERGREEN BE LIABLE FOR ANY INCIDENTAL, SPECIAL, INDIRECT, PUNITIVE OR
    CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE. SOME
    JURISDICTIONS DO NOT ALLOW THE LIMITATION OF INCIDENTAL OR CONSEQUENTIAL
    DAMAGES SO THIS LIMITATION MAY NOT APPLY TO YOU. In no event shall either
    Evergreen's total liability to you for all damages exceed the amount paid
    for this License for the Software.

12. PROPRIETARY RIGHTS. Except as expressly provided for in Section 1 of this
    Agreement, Evergreen and/or its suppliers retain any and all right, title
    and interest in and to the Software. This Agreement grants no additional
    express or implied license, right or interest in any copyright, patent,
    trade secret, trademark, invention or other intellectual property right of
    Evergreen Internet, Inc. or its suppliers. Licensee receives no rights to
    and will not distribute, sublicense, sell, assign, lease market, transfer,
    encumber or suffer to exist any lien or security interest on the Software,
    nor will Licensee take any action that would cause the Software to be placed
    in the public domain. Licensee will not remove, or allow to be removed, any
    Evergreen copyright, trade secret or other proprietary rights notice from
    the Software. Licensee will not make any warranties with respect to the
    Software beyond those made to Licensee by Evergreen under this Agreement.
    Evergreen and its suppliers reserve all rights not specifically granted
    under this License.

        failure to comply and Licensee shall have failed to remedy such failure
        within 30 days of receipt of such notice. In such event, Licensee must
