                 MASTER MANUFACTURING AND PURCHASE AGREEMENT

                      U.S. ASSEMBLIES NEW ENGLAND, INC.

                                       and

                            OpenROUTE NETWORKS, INC.

Agreement  entered  into  this 1st day of  August,  1998,  by and  between  U.S.
Assemblies  New  England  with  principal  offices  at 355  Constitution  Drive,
Taunton,  MA  02780-7355  hereinafter  referred  to as  "U.S.  Assemblies",  and
OpenROUTE  Networks,  Inc.  with  principal  offices at Nine  Technology  Drive,
Westborough,  MA  01581-1799,  hereinafter  referred  to  as  "OpenROUTE".  U.S.
Assemblies  agrees to manufacture the products  described on attached Schedule 1
("Product  Pricing  Schedule") and sell the  finished  Products  exclusively  to
OpenROUTE.  OpenROUTE  agrees  to  purchase  the  finished  Products  from  U.S.
Assemblies. The manufacture,  sale and purchase of the finished Products will be
governed by the terms and conditions of this Agreement.  Additional products may
be added to this  Agreement  from time to time. The terms of this Agreement will
cover any and all product manufactured by U.S. Assemblies for OpenROUTE.

This Agreement consists of the attached following General Terms & Conditions and
the following Schedules (as applicable):

            --Schedule   l-Product   Pricing    Schedule(Including    quantity
            commitments)

1.0    PRODUCT PURCHASE PRICES.

       1.1    Purchase prices ("Purchase  Prices")for the Products are set forth
              on Schedule 1. Pricing for products  that are not final and/or are
              not  listed on  Schedule  1 will be  quoted on a regular  basis to
              OpenROUTE and must be agreed to by both parties.  Purchase  Prices
              exclude all freight  charges,  are FOB U.S.  Assemblies'  Plant of
              manufacture  and  are net of all  taxes,  duties,  and  all  other
              charges.

       1.2    Purchase Prices will be reviewed by U.S.  Assemblies and OpenROUTE
              on an annual  basis,  commencing on the  anniversary  date of this
              agreement.  Any OpenROUTE  products that have a significant change
              in order quantity  (greater than 150% of current order quantities,
              or less than 50% of current order  quantities) will be reviewed on
              quarterly basis,  commencing with start of the next fiscal quarter
              after the initial date of this Agreement.

       1.3    Only in the event of any industry-wide or sole source shortages of
              components  affecting price or delivery schedules,  will OpenROUTE
              agree to negotiate with U.S. Assemblies  equitable  adjustments to
              the Purchase Prices and delivery  schedules,  otherwise prices are
              fixed for the quarter, or the year as the case may be. Upon mutual
              agreement  of the revised  pricing,  the new pricing will apply to
              units shipped  after the  inventory of materials  purchased at the
              lower cost has been consumed.

2.0    OPENROUTE PURCHASE ORDERS.

       2.1    Materials will be purchased and products will be manufactured  and
              shipped  according to a mutually  agreed to schedule.  Once agreed
              to,  purchase of material as well as  manufacture  and shipment of
              Products  will be in accordance  with  OpenROUTE  Purchase  Orders
              ("Purchase  Order(s)").   OpenROUTE  will  issue  U.S.  Assemblies
              Purchase Orders for a minimum of a rolling ninety (90) day period,
              and rolling forecasts for monthly production requirements for nine
              (9) months after the ninety (90) days of Purchase Orders. Purchase
              Orders will state the  material to be  purchased,  the quantity of
              Products to be manufactured  and shipped during the period covered
              by the Purchase  Order, as well as OpenROUTE`s  required  delivery
              date, and agreed to unit price.  U.S.  Assemblies will be measured
              for on time  deliveries  and  therefore  must  deliver  Product to
              OpenROUTE on the  required  delivery  date,  or within a window of
              five (5) days early,  zero (0) days late.  Purchase Orders will be
              confirmed in writing by U.S. Assemblies within 5 days of receipt.

       2.2    OpenROUTE  shall  issue  U.S.  Assemblies  purchase  orders  for a
              rolling  90  day  period,  and  rolling  forecasts  for  the  nine
              (9)months supply of products after the 90 days of purchase orders.
              Purchase orders may be issued each month and the rolling  forecast
              will be updated each month,  or as mutually agreed to between both
              parties,  but in no event  will it be less then once per  quarter.
              OpenROUTE  forecasts of Product  purchases  beyond ninety (90)days
              (or some other mutually  agreed period) are for planning  purposes
              only, and are not firm.

       2.3    U.S.  Assemblies will deliver products on the required due date as
              stated  on  purchase  orders.  Any  change to the  purchase  order
              delivery date requires the written approval of both parties as per
              section 8.1 of this agreement.

       2.3    U.S.  Assemblies  will  purchase  only that  material  required to
              manufacture  Products  according  to  the  quantity  and  delivery
              schedules set forth in Purchase Orders issued by OpenROUTE  during
              the term of this Agreement. U.S. Assemblies will purchase material
              for the Products  according to  OpenROUTE's  Approved  Vendor List
              ("AVL").  With OpenROUTE's prior written consent,  U.S. Assemblies
              may purchase  material in excess of Purchase  Order  requirements,
              such as long  lead  time  components  or  components  which can be
              purchased  in volume at a lower  price.  These  instances  will be
              discussed  and agreed to in writing  by the  parties  prior to any
              actual purchase.

3.0    PAYMENT TERMS.

       3.1    Payment terms are net thirty  (30)days.  The invoice date shall be
              no earlier than the ship date, or a date as mutually  agreed to in
              writing.  Should OpenROUTE fail to make payment to standard terms,
              and mutually agreed upon payment  expectations  become unresolved,
              U.S. Assemblies may; (1) cease shipments to OpenROUTE immediately;
              and/or (2) make some or all future shipments C.O.D.

              component availability.

9.0    NON-RECURRING ENGINEERING CHARGES.

       9.1    On a first time build of new products,  U.S.  Assemblies  will not
              charge  OpenROUTE  for NRE  costs  associated  with pick and place
              machine programming,  original  documentation  packages and solder
              paste stencils.  In subsequent  engineering  revisions requiring a
              new solder stencil, the cost will be charged to OpenROUTE, after a
              formal  quotation  is  provided.   In  no  instance  will  machine
              programming  or  documentation  charges be passed on to OpenROUTE.
              All other NRE charges,  such as test fixtures and  programs,  etc.
              will be quoted and charged to  OpenROUTE  per  standard  terms and
              conditions.

10.0   CHANGES TO THE PRODUCTS.

       10.1   U.S.  Assemblies will not make any changes to the Products without
              OpenROUTE's prior written authorization. U.S. Assemblies will make
              OpenROUTE requested  engineering changes ("EC") to the Products as
              required  by  the   OpenROUTE  EC.  An  EC  request  will  include
              sufficient  information for evaluation of its feasibility and cost
              impact. U.S. Assemblies will respond to EC requests in writing and
              provide cost and other  relevant data within a time period that is
              reasonable considering the magnitude of the EC.

       10.2   OpenROUTE may from time to time change the  specifications for the
              Products or the work  required of U.S.  Assemblies  hereunder  and
              U.S.  Assemblies  agrees to implement  the change per  OpenROUTE's
              requested  schedule,  including a stop work order.  In the event a
              stop work order is issued,  OpenROUTE  agrees to resolve  the stop
              work order within 30 days from the issue date.  If changes  result
              in a  change  in  U.S.  Assemblies'  costs  or  in  the  time  for
              performance,  a price adjustment will be made. Any adjustment must
              be in  writing  and  U.S.  Assemblies  shall  not be  required  to
              implement such change until the Parties have mutually  agreed upon
              the  price.  In the  event  of a  change  necessitated  by  safety
              requirements,  or law, U.S.  Assemblies  agrees to implement  said
              change as soon as possible.

       10.3   U.S. Assemblies agrees not to make any changes in its processes or
              manufacturing  standards  which would effect form, fit or function

              OpenROUTE

       10.4   U.S.  Assemblies  agrees to provide OpenROUTE with two hundred and
              seventy  (270)  days'  notice in the event  they will no longer be
              able or willing to produce  product for OpenROUTE,  and will allow
              OpenROUTE the opportunity to place a last time buy of product.

11.0   INVENTORY INDEMNIFICATION.

       11.1   Upon  cancellation of a Purchase Order, or upon expiration of this
              Agreement  or  termination  of  this  Agreement  for  any  reason,
              OpenROUTE shall be responsible for:

              (i)    all finished Products  scheduled for shipment within thirty
                     (30)days immediately  following U.S. Assemblies' receipt of
                     the cancellation or termination notice (the "Notice");  and
                     all  additional  finished  goods as  mutually  agreed to in
                     writing;

              (ii)   all  work-in-process  at  receipt  of the  Notice,  (and at
                     OpenROUTE's request, U.S. Assemblies agrees to complete all
                     work-in-process); and

              (iii)  all components,  subassemblies and other material purchased
                     to fill a Purchase  Order or  authorized to be purchased by
                     OpenROUTE  which are on hand or on order at  receipt of the
                     Notice.   Without   limitation  this  includes  Piece  Part
                     Inventory  made obsolete or excessive due to changes to the
                     specifications  or Products,  minimum buy  quantities,  and
                     reel  quantities.  Items  (i)-(iii)  are referred to as the
                     "Termination  Inventory".  In  calculating  the quantity of
                     finished Products under (i) above, Products rescheduled for
                     manufacture  and  shipment  during  the  thirty  (30)  days
                     immediately  prior to  receipt of the Notice may be counted
                     by U.S. Assemblies.

       11.2   U.S.  Assemblies  will  make  every  reasonable  effort to use the
              Termination Inventory on other current programs at the Plant where
              the Products are  manufactured,  will make every reasonable effort
              to cancel all outstanding  material-orders  with vendors, and will
              attempt to return  piece parts to vendors.  OpenROUTE  will,  upon
              mutual agreement,  be responsible for verified costs,  charges and
              fees,  including price  differentials,  actually  incurred by U.S.
              Assemblies  to cancel or return  any  portion  of the  Termination
              Inventory  to vendors  and,  the cost to modify the  Products  for
              other programs.

       11.3   Within thirty (30) days from  termination  or  cancellation,  U.S.
              Assemblies  will  invoice,   and  OpenROUTE  will  purchase,   the
              Termination  Inventory  remaining after vendor  cancellations  and
              returns and after  other  program  use, as follows:  (i) for Piece
              Part Inventory and authorized long lead time  components,  at U.S.
              Assemblies'  purchase  price,  including  a mark-up  for  material

              handling equal to U.S.  Assemblies then current  overhead rate for
              materials handling. Details of the then current overhead rate will
              be provided to OpenROUTE,  however, in no event will such overhead
              rate  exceed  six  percent  (6%).  U.S.  Assemblies  will  provide
              OpenROUTE  with  evidence of  purchase  price upon  request.  U.S.
              Assemblies  will  ensure all piece  parts are marked and  packaged
              properly.  (ii)for WIP, at a reasonable pro rata percentage of the
              finished Product purchase price as mutually agreed.

              Regulations. Diversion contrary to U.S. Law is prohibited."

       16.3   Exceptfor  the Products or portions of the Products  which are the
              other party's design,  each party is responsible for their portion
              of the  design of the  Products.  Upon  demand,  that  party  will
              promptly defend, indemnify and hold the other party, its officers,
              directors,  employees,  agents,  successors and assigns,  harmless
              from and against  every kind of cost,  expense or loss  (including
              attorneys' fees and legal costs)directly  relating to any claim or
              threatened  claim:  (a) that any  Product  or portion of a Product
              violates  the  intellectual  property  rights  of  a  third  party
              (foreign or domestic);  (b) that the Product has a design  defect;
              or (c) arising from or related to the distribution, sale or use of
              any  Product or portion of a Product.  The  immediately  preceding
              sentence will apply whether the claim is based upon contract, tort
              or any other legal theory.

       16.4   Each party's  liability for any Product claim shall not exceed the
              purchase price of the Products for which the claim is made.

      IN NO EVENT  SHALL  EITHER  PARTY BE LIABLE TO THE OTHER  PARTY OR A THIRD
      PARTY FOR ANY  SPECIAL,  INCIDENTAL,  PUNITIVE OR  CONSEQUENTIAL  DAMAGES,
      WHETHER BASED UPON  CONTRACT,  TORT, OR ANY OTHER LEGAL THEORY  (INCLUDING
      WITHOUT LIMITATION LOST PROFITS AND OPPORTUNITY).

       16.5   This Agreement is intended solely for the benefit of the executing
              parties  and their  permitted  successors  and  assigns.  No other
              person or entity shall have any rights under or in connection with
              this Agreement.

       16.6   Neither  party may sell,  transfer  or assign any  right,  duty or
              obligation granted or imposed upon it under this Agreement without
              the prior written consent of the other party.

       16.7   The parties  agree that  transmission  of data by EDI  (electronic
              data  interchange)  will  not  occur  until a  separate  agreement
              governing such transmissions is executed. Upon execution, such EDI
              agreement will become an attachment to this Agreement.

       16.8   Neither  party  shall be liable for damages and costs to the other
              party  arising  out of delays or  failures  to perform  under this
              Agreement if such delays or failures result from causes beyond the
              reasonable  control  of a party,  and are not  caused by an act or
              omission of such party.  Notice of any such delays or failures and
              explanation  of their  causes  must be given  to the  other  party
              within  five  (5)  days  of  the  occurrence.  As  soon  as  it is
              reasonably  apparent that the occurrence will likely cause a delay

              claiming the force majeure  event,  OpenROUTE  shall be liable for
              Inventory  Indemnification  per Clause 11 of this Agreement,  This
              force  majeure  provision  may  not  be  invoked  for  failure  or
              inability to make a payment under this Agreement.

              hereunder  and U.S.  Assemblies  is the only entity  authorized to
              manufacture  hereunder.  The individuals  executing this Agreement

              must execute a copy of this Agreement and OpenROUTE  warrants that
              any  and  all  obligations  and  debts  of the  Assignees  will be
              discharged in a timely fashion.

       16.10  This Agreement and  performance  by U.S.  Assemblies and OpenROUTE

              faith  to  settle  any  differences  under  this  Agreement  in  a
              reasonable,  business-like and commercial manner.  However, in the
              event any difference can not be so settled, both parties submit to
              the  personal  jurisdiction  and  venue  of  the  Commonwealth  of
              Massachusetts,   for  the  limited   purpose  of  litigating  such
              differences.

IN WITNESS  WHEREOF,  each party represents that it has caused this Agreement to
be executed on its behalf on the date first above written  (Effective Date) by a

                SETTLEMENT, WAIVER AND GENERAL RELEASE AGREEMENT

     This Settlement, Waiver and General Release Agreement ("Settlement
Agreement") is entered into this 29th day of December, 2000, by and among
Special Situations Fund III, L.P., Special Situations Cayman Fund, L.P. and
Special Situations Private Equity Fund, L.P. (collectively, the "Special
Situations Funds") and ATG Inc., a California corporation ("ATG").  All
capitalized terms used in this Settlement Agreement that are not otherwise
defined shall have the meanings given to them in the Purchase Agreement.

                                    RECITALS

     A.   Pursuant to Common Stock Purchase Agreements dated June 30, 2000 (the
"Purchase Agreements"), the Special Situations Funds acquired an aggregate of
2,000,000 shares of ATG common stock (the "Shares") for an aggregate purchase
price of $4,000,000.

     B.   The Special Situations Funds and ATG wish to settle their
disagreements about rights and remedies that the Special Situations Funds assert
they have under the Purchase Agreements, including but not limited to the
following:

          1.   The Special Situations Funds have asserted, and ATG disagrees,
that the Special Situations Funds have certain rights and remedies against ATG
under the Purchase Agreements, over and above their right to receive Additional
Shares as provided in Section  3(a) of the Purchase Agreements, because ATG
filed a Registration Statement with the Securities and Exchange Commission
("SEC") more than 45 days after the Initial Closing Date and because the
Registration Statement was not declared effective by the SEC within 120 days
after the Initial Closing Date and has not yet been declared effective.

          2.   The Special Situations Funds have also asserted, and ATG
disagrees,  that the Special Situations Funds would have the rights specified
under Section 2(b) of the Purchase Agreement more than ninety days after the
Final Closing Date.

     C.   Solely in the spirit of compromise and without admitting the
contentions of any of the parties against the other, and in order to avoid the
expenses and burdens of litigation, the parties desire to enter into this
Settlement Agreement in order to settle in full all claims, demands, and causes
of action which they have or may claim to have against each other in connection
with the Purchase Agreements.

     NOW, THEREFORE, the parties, in consideration of the mutual promises
contained in this Settlement Agreement, agree as follows:

                                   AGREEMENT

     1.   ATG hereby grants a one-time right to the Special Situations Funds to
have the price for their Shares reset (the "Reset Right") subject to the
following terms and conditions:
<PAGE>

          a.   In the event the average closing price for ATG's common stock
(the "Common Stock") for the thirty (30) trading days prior to November 1, 2001
(the "Reset Price") is below $2.00 per share, the Special Situations Funds may
exercise their Reset Right on all or any part of their original investment in
the Shares (the "Reset Shares") by giving written notice to ATG (the "Exercise
Notice") not later than 5:00 P.M. Pacific Time on November 15, 2001.  Such
written notice shall be deemed effective upon actual delivery to ATG by a
nationally recognized courier service.

          b.   Upon exercising the Reset Right, the Special Situations Funds
shall be entitled to receive from ATG that number of additional, newly issued
shares of Common Stock (the "New Shares") which is sufficient for the average
purchase price of the New Shares and Reset Shares, combined, to equal the Reset
Price; provided, however, that in no event will the Reset Price be lower than
the average closing price of the Common Stock for the fifteen (15) trading days
prior to December 27, 2000, and provided, further, that ATG shall not be
required to issue the New Shares to the Special Situations Funds if, within ten
(10) business days after receiving the Exercise Notice, ATG repurchases all of
the Reset Shares for $2.00 per share by tendering payment to the Special
Situations Funds, by check or wire transfer, in immediately available funds
against delivery of the certificates representing the Reset Shares.

          c.   The parties acknowledge that ATG is subject to rules of the
National Association of Securities Dealers, Inc. ("NASD") requiring ATG to
obtain shareholder approval prior to issuing shares of Common Stock in an amount
that is greater than 20% of ATG's outstanding shares of Common Stock.  The
parties hereby agree that if, in the opinion of ATG's counsel, the NASD rules
require that ATG obtain shareholder approval before issuing the New Shares, then
the obligation to issue the New Shares will be conditioned upon such shareholder
approval.  ATG agrees to use its best efforts to obtain such shareholder
approval, if required, not later than June 30, 2001 and to negotiate with the
Special Situations Funds a reasonable alternative to the issuance of the New
Shares if such shareholder approval is not obtained.

     2.   Waiver.  In consideration of the Reset Right, each of the Special
Situations Funds hereby waives all rights under the Purchase Agreements that
relate in any way to ATG's failure to file the Registration Statement and have
it declared effective in a timely manner, including but not limited to all
rights to receive Additional Shares pursuant to Section 3(a) of the Purchase
Agreements and all rights to rescission and indemnification under Section 3(i)
of the Purchase Agreements.  Each of the Special Situations Funds also waives
all rights under Section 2(b) of the Purchase Agreements.

     3.   General Release.  In further consideration of the Reset Right, each of
the Special Situations Funds, on behalf of their respective predecessors,
successors, assignors and assignees, past and present, hereby fully releases and
discharges ATG, its directors, officers, agents, representatives, attorneys and
employees, past and present, and its predecessors, successors, assignors and
assignees from all claims, actions and causes of action, of any kind or nature
whatsoever, in law, equity, or otherwise, whether fixed or

                                       2

contingent, whether now known or unknown, whether suspected or unsuspected,
which now exist, which existed before the date of this Settlement Agreement, or
which may exist after the date of this Settlement Agreement, relating in any way
to the provisions of the Purchase Agreements which are referenced in Section 2
above.

     4.   ATG agrees to continue to work toward getting the Registration
Statement effective.  If the Registration Statement is not effective by March
31, 2001, the rights of the Special Situations Funds to receive Additional
Shares as provided in Section 3(a) of the Purchase Agreements (which are waived
in Section 2 of this Settlement Agreement) will automatically be reinstated.

     5.   The Special Situations Funds hereby represent and warrant that, except
as provided in this Settlement Agreement, they have not sold, transferred or
assigned any rights or remedies under the Purchase Agreements.

     6.   With respect to this Settlement Agreement, the Special Situations
Funds waive and relinquish, to the fullest extent that the law permits, the
provisions, rights, and benefits of California Civil Code (S) 1542 and other
statutes or common law principles of similar effect.  The Special Situations
Funds acknowledge that they are familiar with, and/or have been advised by their
respective legal counsel of, the provisions of California Civil Code (S) 1542,
which provides as follows:

          A general release does not extend to claims which the creditor does
          not know or suspect to exist in his favor at the time of executing the
          release, which if known by him must have materially affected his
          settlement with the debtor.

     7.   The release set forth above does not release any claims for any breach
of this Settlement Agreement or any claims with respect to the Purchase
Agreements that do not specifically pertain to the subjects of this Settlement
Agreement.

     8.   Each party acknowledges and agrees that it gave careful thought to
this Settlement Agreement, had the opportunity to review this Settlement
Agreement independently with legal counsel of its choice, and/or had the
requisite experience and sophistication to understand, interpret, and agree to
the particular language of the provisions in this Settlement Agreement.  In the
event of an ambiguity in, or dispute regarding the interpretation of, this
Settlement Agreement, the parties agree that no one will resolve any ambiguity
in, or dispute regarding interpretation of, this Settlement Agreement by any
rule providing for interpretation against the party who causes the uncertainty
to exist or against the draftsman.

     9.   The parties agree that this Settlement Agreement sets forth the entire
agreement between the parties relating to the subject matter of this Settlement
Agreement.  The parties agree that this Settlement Agreement supersedes any and
all prior or contemporaneous agreements or understandings between them.

     10.  The parties may not waive any provision of this Settlement Agreement
except by a written agreement which all of the parties have signed; a waiver of
any provision of this Settlement Agreement will not constitute a waiver of any
other provision.  The parties may modify or amend this Settlement Agreement only
by a written agreement that all the parties have signed.

     11.  The parties may execute this Settlement Agreement in one or more
counterparts, each of which constitutes an original, and all of which constitute
one and the same Settlement Agreement.

     IN WITNESS WHEREOF, the undersigned have executed this Settlement Agreement
as of the above date.
