                  specified below, under IBIS's applicable patent and trade
                  secret rights in Licensed Patents, Licensed Technology [ ] to:

                  of SIMOX systems and components thereof; (b) lease, sell, or
                  otherwise transfer SIMOX systems and components thereof to
                  Affiliates; and (c) sublicense such Affiliates to use and
                  practice any process in the use of such SIMOX systems and
                  components thereof. For the avoidance of doubt, IBM agrees
                  that the foregoing right to sublicense Affiliates does not
                  include the right to license Affiliates to make or have made a

                  works within IBM and to Affiliates, subject to the following
                  condition:

                  IBM may grant sublicenses under IBIS's copyrights in software
                  in object code format necessary for the operation of a SIMOX
                  system to its Affiliates' purchasing systems licensed

                  (d)   prohibit reverse assembly, reverse compilation, or other
                  translation of product code or any portion thereof.

                  For the avoidance of doubt, IBM agrees that it is not
                  permitted to act under the foregoing license until it has
                  elected one of the options set forth in Section 3.5.

         3.3      No license or immunity is extended by a Party either directly
                  or by implication, estoppel, or otherwise except as explicitly

                  of such [ ], after which initial period, IBIS may incorporate
                  such [ ] in a system sold to any customer. For the avoidance
                  of doubt, this license granted by IBM does not cover
                  Intellectual Property Rights pertaining to methods of
                  operation of an ion-implanting system or to processes used in
                  making or treating wafers and/or integrated circuits.

         3.5      IBM shall have the option, to be exercised in its sole
                  discretion and at any time, to elect either License Option A
                  or License Option B by delivery of a written notice to IBIS.
                  Exercise of Option A or Option B shall be subject to the
                  conditions of Section 3.5.1 or Section 3.5.2, as the case may
                  be.

                  documentation to IBM upon receipt of notice. The consent of
                  IBIS is not required for delivery of the documentation under
                  this License Option A and IBIS hereby waives any right it may
                  have to object to such transfer. The royalty payments under
                  this License Option A shall be as specified in Section 6. Upon

                  License Option B by delivery of written notice to the Escrow
                  Agent stating: a) [ ]; or b) that IBIS has failed to satisfy
                  one or more of the following conditions and IBIS has not cured
                  such failure within [ ] days after notification by IBM of the
                  failure.

         3.5.2.1        The conditions are that IBIS:

         (a)      [   ]

         (b)      [   ]

         (c)      [   ]

         (d)      [   ]

                  The Escrow Agent shall immediately deliver the escrow
                  documentation to IBM upon receipt of notice. The consent of
                  IBIS is not required for delivery of the documentation under
                  this License Option B. IBIS hereby waives any right it may
                  have to object to or otherwise prevent the Escrow Agent from
                  completing such transfer and agrees that its only recourse
                  against IBM in the event of a dispute concerning such transfer
                  shall be a claim against IBM for monetary damages. The royalty
                  payments shall be as specified in Section 6. IBIS shall
                  deliver the training and Technical Assistance specified in
                  Appendix A at times mutually agreed on but no later than the
                  times specified in Appendix A.

         3.6      IBIS agrees, within [ ] days after the last signature date of
                  this Agreement, to review with IBM at IBIS' place of business
                  the documentation and updates thereof listed in Appendix B.
                  After such review, IBIS shall transmit such documentation to
                  an Escrow Agent chosen by mutual agreement of the Parties.
                  Such Escrow Agent shall hold such documentation pursuant to an
                  escrow agreement to be executed concurrently herewith. The
                  parties shall share the cost of the escrow equally. For
                  convenience in administration, IBIS shall pay the escrow Agent
                  and invoice IBM for its share of the 


                                       48



                  payment. The Parties agree that such escrow agreement shall
                  permit IBM to inspect (but not copy) the documentation at the
                  Escrow Agent's premises.

         3.7      IBIS represents and agrees that it will not initiate any work
                  (or otherwise take any steps in reliance) on a SIMOX system
                  for sale to IBM unless and until IBIS has received an
                  applicable written purchase order from IBM. IBM shall have no
                  obligation to exercise any of the options granted to it under
                  this Agreement.

4        CONFIDENTIAL INFORMATION

         4.1      The prior Confidential Disclosure agreement between the
                  Parties concerning confidential information is terminated as
                  of the Effective Date and any information disclosed thereunder
                  shall be deemed to be disclosed under this Agreement as of the
                  Effective Date. The confidentiality provisions of the
                  Equipment Procurement Master Agreement between the Parties
                  having an effective date in May, 1996 are superseded only with
                  respect to Confidential Information disclosed under and marked
                  in accordance with this Agreement.

         4.2      Subject to the provisions of Section 3, for a confidentiality
                  period as set forth below, the receiving Party agrees to use
                  the same care and discretion to safeguard Confidential
                  Information of the disclosing Party and to avoid release of
                  such Confidential Information outside of the receiving Party
                  as it employs with similar embodiments of information of its
                  own which it does not desire to publish, disclose, or
                  disseminate, but in no event less than reasonable care.

         4.3      Obligations of confidentiality and restricted use set forth
                  herein shall extend until December 31, 2008.

         4.4      The obligations of confidentiality herein shall not apply to
                  information that:

                      (a)   Is already in the possession of the receiving Party
                  r any of its Subsidiaries without obligation of confidence;

                      (b)   Is independently developed by the receiving Party
                  r any of its Subsidiaries;

                      (c)   Is or becomes publicly available without breach of
                  his Agreement;

                      (d)   Is rightfully received by the receiving Party from
                   third Party;

                      (e)   Is released for disclosure by the disclosing Party
                  ith its written consent;

                      (f)   Is required to be disclosed in a patent
                  pplication; or

                      (g)   Is inherently disclosed in the use, lease, sale, or
                  ther distribution of any present or future product or
                  service by or for the receiving Party or any of its
                  Affiliates.


                                       49



         4.5      All disclosures of Confidential Information by IBIS or IBM, as
                  the disclosing Party, shall be made by or under the
                  supervision of its Technical Coordinator, or his designee, to
                  the receiving Party's Technical Coordinator, or his designee.
                  In the event of inadvertent disclosure, either Party may give
                  notice to the other Party that such inadvertently disclosed
                  information was confidential and the receiving Party
                  thereafter shall treat in good faith such information as
                  Confidential Information.

         4.6      All disclosures of information will be deemed to be
                  non-confidential unless specifically designated at the time of
                  disclosure (as provided in Section 4.7 below) as including the
                  Confidential Information of a Party.

         4.6.1    Notwithstanding the foregoing, Inventions created and
                  Confidential Information disclosed in the course of joint work
                  or discussions between the Parties shall be deemed to be the
                  Confidential Information of the employer(s) of the individuals
                  creating them, whether or not the pertinent information is
                  marked or summarized in a resume. The Parties agree to make
                  reasonable efforts to document and mark such joint work or
                  discussions.

         4.7      Information, including Confidential Information, of a Party
                  shall be disclosed in writing in English (including such
                  information recorded in a medium such as a tape or disk),
                  which writing shall state the date of disclosure, that the
                  information contained therein is confidential and that it is
                  being disclosed pursuant to this Agreement, and shall contain
                  an appropriate legend, such as "IBIS Confidential
                  Information". If such disclosure is orally and/or visually
                  made, then it shall be confirmed in a written resume within
                  twenty (20) days following such disclosure. The resume will
                  specifically recite that information which is confidential.
                  Such resume will have such information that is confidential
                  identified as "IBIS Confidential (or IBM Confidential)
                  Information". The receiving Party may make a reasonable number
                  of copies of such writings or resumes.

         4.8      A receiving Party possessing Confidential Information of the
                  other Party may disclose it to a vendor or to a subcontractor
                  (or to a sublicensee that in turn may disclose to a vendor or
                  subcontractor), for the purpose of exercising the license
                  specified in Section 3. under restrictions on disclosure at
                  least as stringent as those set forth herein. The receiving
                  Party may only authorize such vendor, subcontractor or
                  sublicensee to use such Confidential Information only for the
                  benefit of such receiving Party. If disclosure is compelled as
                  testimony or evidence in a judicial or legislative proceeding,
                  the Party under compulsion to disclose shall immediately
                  notify the owner Party and shall avail itself of all
                  reasonable protection at the reasonable expense and with the
                  express prior concurrence in writing of the Party owning the
                  applicable Confidential Information, such as protective orders
                  or exemptions from Freedom of Information Act availability, as
                  may be reasonably available and effective to protect the
                  Confidential Information in question.

         4.9      It is understood that receipt of Confidential Information
                  under this Agreement will not create any obligation in any way
                  limiting or restricting the assignment and/or 




                                       50



                  reassignment of IBIS employees within IBIS or IBM employees
                  within IBM.

         4.10     Each Party represents that it has, and agrees to maintain, an
                  appropriate agreement with each of its employees who may have
                  access to any Confidential Information sufficient to enable
                  each Party to comply with all the terms of this Agreement.

         4.11     All disclosures of information under this Agreement shall be
                  governed by the applicable statutes and regulations of the
                  United States Government regarding the export of technical
                  information. Each Party agrees to comply, and do all things
                  reasonably necessary for the other Party to comply, with all
                  applicable laws, regulations and ordinances of any country
                  having jurisdiction over the subject matter hereof, including
                  but not limited to the regulations of the United States
                  Department of Commerce and Department of State relating to the
                  export or re-export of technical data or the direct product
                  thereof, insofar as they relate to the activities to be
                  performed under this Agreement. Each Party agrees to obtain
                  any required government documents and approvals prior to the
                  export or re-export by it of any technical data disclosed to
                  it or the direct product related thereto.

         4.12     IBIS shall make available an initial data package [ ], as
                  specified in Section 3.6, Appendix A, and Appendix B, for
                  inspection and evaluation by IBM at IBIS' place of business
                  and subsequent transmission to the Escrow Agent. IBIS shall
                  promptly correct deficiencies in the data on IBM's request.
                  When IBM is satisfied that the data are adequate, IBIS shall
                  forward the data to the Escrow Agent.

         4.12.1   In the event that IBM exercises its license under Section
                  3.5.1 or 3.5.2, IBIS shall continue to deliver data updates,
                  which IBM may immediately use under the terms hereof.

         4.13     The conditions for release of data hereunder by the Escrow
                  Agent shall be as set forth herein and shall not be affected
                  by the existence of different conditions in, or by the status
                  of the escrow (i.e. whether released or not) under, the
                  Equipment Purchase Master Agreement. For the avoidance of
                  doubt, the data may be released under the Equipment Purchase
                  Master Agreement before or after the release of data
                  hereunder.

5        OWNERSHIP OF INTELLECTUAL PROPERTY

         5.1      Each Party shall have and retain the sole and exclusive
                  ownership of all Intellectual Property Rights that are made or
                  created solely by it or its employees or agents in the course
                  of the Program.

         5.2      Any Intellectual Property Rights made or created jointly by
                  the Parties or employees or agents of the Parties in the
                  course of the Program shall be owned jointly. Joint Inventions
                  shall be jointly owned, title to all patents issued thereon
                  shall be joint, all expense incurred in obtaining and
                  maintaining such patents, except as provided herein, shall be
                  jointly shared. Each Party shall have the unrestricted right
                  to license third parties under such jointly owned Intellectual
                  Property Rights without 


                                       51



                  accounting.

         5.2.1    Unless otherwise agreed, joint owners of Intellectual Property
                  Rights shall engage outside counsel to perform tasks
                  associated with securing the legal protection of such
                  Intellectual Property Rights and shall share the costs thereof
                  equally. In the event that one Party elects not to seek patent
                  protection for any joint Invention in any particular country
                  or not to share equally in the expense thereof with the other
                  Party, the other Party shall have the right to seek or
                  maintain such protection at its own expense in such country
                  and shall have full control over the prosecution and
                  maintenance thereof even though title to any patent issuing
                  therefrom shall be jointly owned. Such one Party shall have no
                  obligation to pay expenses of securing and maintaining such
                  Intellectual Property Rights in any country unless it has so
                  agreed in writing.

         5.3      Each Party shall give the other Party all reasonable
                  assistance in obtaining patent protection and in preparing and
                  prosecuting any patent application filed by the other Party,
                  and shall cause to be executed assignments and all other
                  instruments and documents as the other Party may consider
                  necessary or appropriate to carry out the intent of this
                  Section 5.

6.       PAYMENT

         6.1      From and after the Effective Date, IBM shall pay to IBIS a
                  royalty comprising the amount listed in the appropriate column
                  of Table I for each Licensed Product made by or for IBM and/or
                  sold, leased or otherwise transferred or disposed of by or for
                  IBM.

                                       TABLE I




             Number of
              Machines               Option A                Option B
                                                         
                [ ]                    [ ]                     [ ]
                [ ]                    [ ]                     [ ]
                [ ]                    [ ]                     [ ]
                [ ]                    [ ]                     [ ]




         6.2      The royalty of Section 6.1 shall accrue when a Licensed
                  Product is first put into service by IBM or is first sold,
                  leased or otherwise transferred or disposed of by or for IBM.
                  For the purpose of determining such royalty, Licensed Products
                  shall be considered sold, leased or otherwise transferred or
                  disposed of when invoiced. If not invoiced, then Licensed
                  Products are to be considered sold, leased or otherwise
                  transferred or disposed of when delivered or when paid for, if
                  paid for before delivery. If not invoiced, delivered or paid
                  for before delivery, Licensed Products are to be considered
                  sold, leased or otherwise transferred or disposed of at the
                  earlier of when put into use or when possession is transferred
                  to a third Party. When Licensed 


                                       52



                  Products are sold, leased or otherwise transferred or disposed
                  of in conjunction with other products or services provided,
                  sold, leased or otherwise transferred or disposed of by IBM,
                  IBM agrees to separately invoice such Licensed Products from
                  such other products or services.

         6.3      Accrued royalties shall be calculated and paid on a calendar
                  quarterly basis. Any royalties due IBIS for any calendar
                  quarter shall be paid to IBIS by [ ] days after the end of
                  each calendar quarter. IBM may deduct from the accrued
                  royalties calculation in this Section 6.3 those royalties
                  accrued on Licensed Products which have been returned to IBM
                  or for which credit allowances have been made.

         6.4      Within [ ] days of each calendar quarter, IBM shall furnish to
                  IBIS a written statement showing the Licensed Products that
                  were made, used, sold, leased and/or transferred or otherwise
                  disposed of during the immediately preceding calendar year and
                  the royalties payable thereon. If no royalties are payable,
                  that fact shall be shown on such statement.

         6.5      IBIS shall have the right, at its expense, to have an
                  independent accountant acceptable to IBM inspect relevant
                  records of IBM during normal business hours and on reasonable
                  notice, to verify that the number of SIMOX systems made by or
                  for IBM is as reported to IBIS, and for no other purpose. IBIS
                  shall require such accountant to execute an agreement
                  permitting disclosure of such number only to IBIS and its

                  (a)    the obligations of the Parties to deliver Improvements
                  shall terminate; and

                  payment obligations shall survive.

                  all royalties, fees, and other payments due or accrued
                  hereunder as of the date of termination shall remain payable.

                  reasonable effort that Party shall not have been able to

                  required licenses and approvals and (b) to comply with all
                  applicable laws, rules and regulations, including, but not
                  limited to, the Regulations of the United States Government
                  relating to the export and re-export of technical data,
                  commodities, and products produced as a result of the use of
                  such data. Each Party hereto agrees that it will not export or
                  re-export, directly or indirectly, any technology, software,
                  and/or commodities furnished under this Agreement, or the
                  direct product thereof, to any country, or the nationals
                  thereof, specified in such laws, rules, 



                                       58


                  regulations, and ordinances referred to above as an
                  unauthorized destination without IBIS or IBM first obtaining
                  U.S. Government approval.

         11.5     The captions used in this Agreement are for convenience of
                  reference only and are not to be used in interpreting the
                  obligations of the Parties under this Agreement.

         11.6     Nothing contained herein, or done in pursuance of this
                  Agreement, shall constitute the Parties as entering upon a
                  joint venture or partnership or shall constitute either Party
                  hereto the agent for the other Party for any purpose or in any
                  sense whatsoever.

         11.7     Either Party may disapprove the assignment of any of its
                  former employees to perform work under this Agreement on its
                  premises by the other Party and such personnel will not be so
                  assigned. Each Party will take appropriate preventive steps,
                  before the assignment of any of its employees to perform work
                  under this Agreement, that that Party reasonably believes will
                  ensure that its employees will not engage in inappropriate
                  conduct while on the other Party's premises. Inappropriate
                  conduct shall include, but not be limited to: 1) being under
                  the influence of, or affected by, alcohol, illegal drugs or
                  controlled substances or engaging in their use, distribution
                  or sale; 2) the possession of a weapon of any sort; and 3)
                  harassment, threats or violent behavior.

         11.8     Representatives and personnel of each Party, during the time
                  they are present on the premises of the other Party shall be
                  subject to all rules and regulations prevailing on such
                  premises. Each Party shall be responsible for the payment of
                  all compensation and expense of its respective representatives
                  and personnel. None of the representatives or personnel of
                  either Party shall be considered, for any reason, to be an
                  employee or agent of the other.

         11.9     Each Party represents that it has, or will have in place,
                  established procedures and agreements with its Subsidiaries,
                  employees or others, including subcontractors and vendors,
                  whose services the Party may require, sufficient to enable the
                  Party to comply with all the provisions of this Agreement.

         11.10    In the event of any inconsistency between the terms and
                  conditions of this Agreement and language set forth in the
                  Appendices, the inconsistency shall be resolved by giving
                  precedence to the terms and conditions of this Agreement.

         11.11    Any written notice or communication required to be made or
                  given to either Party hereto, pursuant to this Agreement,
                  shall be deemed to have been sufficiently given on the date of
                  mailing if sent by registered or certified mail, postage
                  prepaid, and addressed as set forth below, or to such other
                  address as is designated by written notice given to the other
                  Party:

                  11.11.1           In the case of IBM:
                                    Director of Licensing

                                    Thornwood, NY, 10594

                  11.11.2           In the case of IBIS:
                                    Al Alioto

                                    Ibis Technology Corporation
                                    32 Cherry Hill Drive
                                    Danvers, MA 01923

         11.12    The rights and obligations of Sections 3, 4, 5, 7, 8, 10, and
                  11 and the obligations of nondisclosure and restricted use of
                  this Agreement shall survive and continue after any expiration
                  or termination of this Agreement and shall bind the Parties
                  and their successors and assigns.

         11.13    No failure on the part of any Party to exercise, and no delay
                  in exercising, any right, power, or remedy hereunder shall
                  operate as a waiver thereof or as a waiver of any other right,
                  power, or remedy hereunder or to the performance of any Party;
                  and no single or partial exercise by a Party of any right,
                  power, or remedy hereunder shall preclude any other or further
                  exercise thereof or the exercise of any other right, power, or
                  remedy.

         11.14    Nothing contained in this Agreement shall be construed as
                  conferring any right to use in advertising, publicity or other
                  promotional activities any name, trade name, trademark or
                  other designation of either Party (including any contraction,
                  abbreviation or simulation of any of the foregoing); and each
                  Party agrees not to disclose the terms and conditions of this
                  Agreement except as may be required by law or government rule
                  or regulation, without the express written consent of the
                  other Party. Notwithstanding the foregoing, the Parties shall
                  be permitted to disclose a summary of pertinent Sections of
                  this Agreement that are reasonably necessary for disclosing
                  and/or licensing under this Agreement, provided, however, that
                  such disclosure is under a written agreement containing
                  restrictions of confidentiality at least as stringent as those
                  contained herein.

         11.15    Except for the provisions of Section 11.1, in no event will a
                  Party be liable to the other Party for incidental damages,
                  lost profits, lost savings special damages, or consequential
                  damages, regardless of whether the claim is for breach of
                  contract, breach of warranty, tort (including negligence),
                  failure of a remedy to accomplish its purpose or otherwise,
                  even if such Party has been advised of the possibility of such
                  damages.

         11.16    Each Party shall be liable to the other Party up to a maximum
                  of the greater of (a) [ ], or (b) the amount of unpaid
                  royalties owed by such Party to the other Party hereunder plus
                  [ ], for all actual direct losses or damages sustained by the
                  other Party (other than those arising under Section 11.1) that
                  are proximately caused by the acts or omissions of such Party
                  under this Agreement.


                                       60




         11.17    Except as explicitly stated herein, a Party shall not assign
                  any of its rights, privileges or obligations under this
                  Agreement without the prior written consent of the other
                  Party. Any attempted assignment in derogation of the foregoing
                  shall be void.

         11.18    The Equipment Purchase Master Agreement, any task orders
                  thereunder, and the Wafer Purchase Agreement between the
                  Parties are not superseded by this Agreement, except as
                  explicitly stated herein. By way of example and not as a
                  limitation, the license to make up to two tools granted to IBM
                  in Section 13 of EPMA 07482 between the Parties is not
                  superseded and that license may be exercised by IBM, in its
                  sole discretion, in addition to the license granted hereunder.

         11.19    This Agreement shall not be binding upon the Parties until it
                  has been signed below by or on behalf of each Party, in which
                  event it shall be effective as of the date first above
                  written. Except as provided in Section 11.18, this Agreement
                  constitutes the entire agreement between the Parties with
                  respect to the subject matter hereof and shall supersede all
                  previous communications, understandings and agreements,
                  whether oral or written, between the Parties relating to the
                  subject matter hereof. No amendment or modification of this
                  Agreement shall be valid or binding upon the Parties unless
                  made in writing and signed on behalf of such Parties by their
                  respective authorized representatives. The requirement of
                  written form may only be waived in writing.


                                       61



         IN WITNESS WHEREOF, the Parties have caused this Agreement to be
executed by their duly authorized representatives, who by their signature
represent that they are so authorized, to be effective as of the day and year
first above written.
