2.3      In order to facilitate SpectRx planning of production, and to assist
         SpectRx in making certain decisions relative to inventory of long lead
         items, Roche shall submit to SpectRx a non-binding estimate of its
         requirements of Instruments monthly covering a forward period of not
         less than twelve 12 months, beginning six months after the signing of
         this agreement. Upon receipt of Roche's estimate, if SpectRx determines
         that it has insufficient capacity to meet the quantities stated in the
         estimate, it shall notify Roche within fifteen (15) days of the date of
         receipt of Roche's estimate that such condition exists, and present
         recommendations regarding capacity changes to meet Roche's estimate. In
         the event this Agreement is terminated (other than a termination by
         Roche Diagnostics pursuant to Section 9.2), Roche shall be responsible
         for reasonable quantities of components purchased, or reasonably
         committed to be purchased by SpectRx, at lead-time in accordance with
         the non-binding estimate. In the event of such termination SpectRx
         shall use commercially reasonable efforts to


                                                                          Page 2

         return the components while minimizing any cost associated with the
         activity. Roche Diagnostics will buy from SpectRx any components which
         are unable to be returned pursuant to the preceding sentence, and pay
         any restocking charges that have been approved in writing by Roche
         Diagnostics, such approval shall not be unreasonably withheld.

2.4      The first purchase order issued under this Agreement will cover the
         first three (3) months of supply. Subsequently, Roche shall issue
         purchase orders, containing specific instructions concerning quantity,
         delivery schedule, invoicing, etc., from time to time for the supply of
         Instruments based on a manufacturing lead-time [purchase order receipt
         to delivery of Instruments] of ninety (90) calendar days.

2.5      SpectRx warrants to Roche that it has or will have a minimum installed
         equipment manufacturing capacity to produce one hundred and twenty-five
         (125) Instruments per month (based on a single shift) at Product Launch
         (as defined in the Development Agreement). SpectRx will maintain
         installed equipment manufacturing capacity (based on the number of
         shifts that are currently staffed) of at least thirty percent (30%)
         above the six (6) month average (adjusted monthly) order rate, which
         shall be calculated by adding the forward six (6) months of purchase
         order and estimated requirements and dividing the sum by six (6).


2.6      SpectRx shall not make any change to the Instrument or the manufacture
         thereof that may affect the form, fit, function, reliability, or
         appearance of the Instrument without the prior written consent of Roche

         Roche Diagnostics agrees to implement its current warranty card
         tracking system for the Instruments sold by Roche Diagnostics pursuant
         to this Agreement.

6.0      WARRANTIES AND INDEMNIFICATION

6.1      SpectRx warrants to Roche Diagnostics that all Instruments to be
         supplied hereunder will upon shipment meet the agreed upon
         Specification, will be free from defects in materials and workmanship,
         and will be properly packed and labeled according to the Specification;
         provided, however, in respect of defects in materials and workmanship,
         and in respect of packaging and labeling, should a matter be covered by
         the Specification, the Specification will control. This warranty shall
         apply for a period of twenty-four (24) months after the date of
         shipment by SpectRx, or twelve (12) months from date of delivery to the
         end user, whichever occurs first. SpectRx shall satisfy this warranty
         requirement by repairing or replacing, at no charge to Roche
         Diagnostics at such time, each defective Instrument that is returned to
         it prior to the expiration of the warranty period. SpectRx shall not be
         liable for loss or damages arising out of misuse of the Instrument by
         Roche Diagnostics, its agents or customers. Such repair or replacement
         will be done in accordance with Instrument Service/Loaner


                                                                          Page 5
   6

         Procedure as set forth in Exhibit F attached hereto, which may be
         amended from time to time upon written request by SpectRx and approval
         by Roche Diagnostics which approval shall not be unreasonably withheld.

6.2      SpectRx warrants that the Instrument annualized field failure rate
         based on instruments returned to SpectRx whose performance is found to
         be non conforming to the Specifications other than due to misuse or
         abuse for Instruments delivered to Roche Diagnostics in a given month
         ("Failure Rate") will be less than 30% during the first year after
         Product Launch (as defined in the Development Agreement) and less than
         15% after the end of the second year after Product Launch. SpectRx will
         make all commercially reasonable efforts to reduce the Failure Rate, at
         SpectRx's expense, to the lowest practical level. SpectRx will conduct
         a failure analysis on all field failures as required by the U.S. Food
         and Drug Administration ("FDA") regulations, with respect to defective
         Instruments that are returned under Section 6.1 hereof by end users.
         Root causes of such defects will be determined where possible, and
         commercially reasonable corrective actions will be taken on the
         Instrument design and/or manufacturing process as appropriate. SpectRx
         will track failure rates and failure modes in respect of such
         Instruments, and provide at least quarterly reports of such findings,
         trends and corrective action programs as to same to Roche Diagnostics.
         Provided SpectRx uses such efforts and otherwise complies with the
         covenants set forth in this Section 6.2, the breach of the warranty set
         forth in the first sentence of this section 6.2 will not constitute a
         breach for purposes of Section 9.2 hereof or otherwise. For any monthly
         period where the Failure Rate limit is exceeded, the minimum annual
         volume requirements as stated in Section (1) of Exhibit B of the
         Development and License Agreement will be reduced by the number of
         defective Instruments returned from said monthly period in excess of
         the Failure Rate limit. Nothing in this Section 6.2 shall affect
         SpectRx's obligations under Sections 6.1,6.3,6.4,6.5, or 6.7.


6.3      With respect to any instruments manufactured by SpectRx, SpectRx shall
         be liable for and shall indemnify, defend and hold Roche Diagnostics
         harmless against any and all claims, suits, proceedings, recoveries,
         and damages, including but not limited to costs and expenses of total
         or partial Instrument recall, whether initiated voluntarily by Roche
         Diagnostics or at the direction of the FDA (collectively "Recall
         Claims") arising out of, based on, or caused by defects in material or
         workmanship or failure of the Instrument to conform to the
         Specification, although in no event will SpectRx's aggregate liability
         in respect to all Recall Claims exceed [ * ]. Such recall, if initiated
         by Roche Diagnostics, shall be based on the reasonable belief by Roche
         Diagnostics that if no such recall action is taken at such time, the
         FDA would reasonably be expected to initiate such recall action. In no
         event shall (i) SpectRx be liable for or be required to indemnify Roche
         Diagnostics for or hold it harmless from any claims arising in whole or
         in part from or based on, or caused by defects or deficiencies in any


                                                                          Page 6

         features of the Instrument designed by Roche Diagnostics or its
         Affiliates, any component of the Instrument designed by Roche
         Diagnostics or the literature supplied by Roche Diagnostics for use
         with the Instrument, or claims made by Roche Diagnostics or its agents,
         (ii) SpectRx be liable to Roche Diagnostics or any person for any loss
         or damage to the extent caused by any misuse of the Instrument or
         reliance upon the Instrument in respect of the issuance of any medical
         opinion, (iii) SpectRx be liable to Roche Diagnostics or any person for
         any implied warranties for merchantability or fitness for a particular
         purpose or any express warranties. Roche Diagnostics agrees to
         incorporate in its documentation to its customers that its warranty for
         product liability will not exceed the repair or replacement of the
         Instrument or the return of the price thereof. SpectRx shall promptly
         notify Roche Diagnostics of any situation which may affect a decision
         to recall the Instrument, however, Roche Diagnostics shall have the
         final authority to institute a voluntary recall, which authority shall
         not be exercised unreasonably. Notwithstanding the foregoing, in no
         event shall either party be liable to the other party or any other
         person for any incidental or consequential damages pursuant to this
         Section 6.3 or any other provision of this Agreement or otherwise
         arising from or in any way connected with the purchase or use of the
         Instrument.

6.4      SpectRx shall indemnify, defend and hold Roche Diagnostics harmless
         from any and all claims, demands, actions and causes of action against
         Roche Diagnostics in connection with any and all injuries, damages or
         liabilities of any kind whatsoever directly or indirectly attributed to
         manufacture of the Instrument or component deficiencies or defects, or
         failure of the Instrument to conform to the Specification, although in
         no event shall SpectRx's liability in respect of the foregoing
         indemnity as to any single occurrence exceed [ * ], or in the aggregate
         for all Instruments, exceed [ * ]. This indemnification obligation
         shall include, without limiting the generality of the foregoing
         reasonable attorney's fees, and other costs or expenses incurred in
         connection with the defense or settlement of any and all such claims,
         demands, actions or causes of actions.

6.5      As of the date hereof, SpectRx warrants and represents to Roche
         Diagnostics that SpectRx has no actual knowledge of any infringement of
         the existing patent or other intellectual property rights of any other
         party which would be caused by the manufacturing, offering for sale,
         sale or use of the Instruments. SpectRx will indemnify and hold Roche
         Diagnostics harmless from and against any claims, actions or demands
         (including, without limitation, attorney's fees, interest and
         penalties) based upon the alleged infringement by the manufacture,
         offering for sale, sale, or use of the Instrument of any patent or
         other intellectual property rights now or hereafter existing, provided,
         and notwithstanding anything stated herein to the contrary, SpectRx's
         liability pursuant to this Section 6.5 shall in no event exceed
         [ * ] in aggregate. If any such claim, action or demand based upon
         intellectual property infringement is made against Roche Diagnostics,
         SpectRx shall promptly initiate commercially reasonable efforts to the
         extent necessary:


                                                                          Page 7




         (*)   Confidential treatment requested pursuant to a request for
               confidential treatment filed with the Securities and Exchange

                  a)       secure permission, with Roche Diagnostics consent,
                           which will not be unreasonably denied, to continue
                           the manufacture and supply of Instruments to Roche
                           Diagnostics, with one-half of any royalties payable
                           for any such Instrument supplied to Roche Diagnostics
                           added (without adjustment for margin corresponding
                           thereto) to the price of the Instrument, and also
                           such amount, on the same dollar-for-dollar basis
                           shall be added to the Unadjusted Maximum Price as set
                           forth in Exhibit B attached hereto applicable
                           thereto, or

                  b)       provide an Instrument which is non-infringing yet
                           still meets the agreed upon Roche Diagnostics
                           requirement as contained in this Agreement.



         Roche Diagnostics will not file an infringement claim against the
         SpectRx licensed device based on existing or in licensed intellectual
         property, so long as Roche has the marketing rights.

6.6      Roche Diagnostics will indemnify and hold SpectRx harmless from any and
         all claims, demands, actions or causes of action against SpectRx, in
         connection with any and all injuries, losses damages or liability of
         any kind whatsoever directly or indirectly attributed to features of
         the Instrument designed according to Roche Diagnostic's or its
         Affiliates' instructions or directions or any omission or misstatement
         in the literature supplied by Roche Diagnostics for use with the
         Instrument. This indemnification obligation shall include, without
         limiting the generality of the foregoing, reasonable attorney's fees
         and other costs or expenses incurred in connection with the defense or
         settlement of any such claim, demand, actions, or causes of action.
         Notwithstanding the foregoing, in no event shall Roche Diagnostics be
         liable to SpectRx or any other person for any incidental or
         consequential damages arising from or in any way connected with the
         purchase or use of product.

6.7      Roche Diagnostics and SpectRx agree in conjunction with their
         obligations under this Agreement to avoid knowingly designing and/or
         developing any item that infringes any patent of a third party. If
         either party becomes aware of an issue relating to patent infringement
         during the course of performing hereunder, it will promptly notify the
         other party.

6.8      If Roche Diagnostics licenses third party intellectual property in
         order to make, use, offer for sale and sell Instruments and any other
         things supplied by SpectRx under this Agreement, then the price paid to
         SpectRx for such Instruments and other things shall be reduced by one
         half of the amount paid to the third party for such license.


                                                                          Page 8

         confidentiality provided for in the amended and restated Development
         Agreement.

7.2      Upon any termination or expiration of this Agreement, the parties agree
         that the receiving party shall promptly return all confidential
         information to the transmitting party, except for one copy thereof that
         shall be kept in a limited access file by the receiving party and used
         only for monitoring its obligations hereunder. In the event of a loss
         of any item containing such confidential information, the party
         claiming said loss will promptly notify the other party in writing.

8.0      EMPLOYEES

8.1      Personnel assigned by SpectRx to perform services under this Agreement
         will be employees or contractors of SpectRx and will not for any
         purpose be considered employees or agents of Roche Diagnostics. SpectRx
         assumes full responsibility for the actions of such personnel while
         performing services hereunder and shall be solely responsible for their
         supervision, daily direction and control, payment of salary (including
         withholding of income taxes and social security), workers compensation,
         disability benefits and the like.

8.2      Personnel assigned by Roche Diagnostics to perform services under this
         Agreement will be employees or contractors of Roche Diagnostics and
         will not for any purpose be considered employees or agents of SpectRx.

9.0      TERM AND TERMINATION

9.1      Unless terminated pursuant to the terms hereof, the term of this
         Agreement shall be coincident with the term of the Development
         Agreement. The parties agree that in the event of termination of this
         Agreement, all confidential information, documents, materials, tools,
         etc. which are the property of either party shall be promptly returned
         to such party.

9.2      Either party may terminate this Agreement by written notice to the
         other in the event (i) the other party materially breaches this
         Agreement and does not cure


                                                                          Page 9
   10

         such breach with thirty (30) days of written demand for cure; or (ii)
         by written notice upon the liquidation or bankruptcy of, or an
         assignment for the benefit of creditors of, or a declaration of
         insolvency by, the other party. Termination of this Agreement by
         SpectRx pursuant to this Section 9.2 shall constitute a termination of
         the Development Agreement and the Marketing License granted thereunder.
         In the event of termination by SpectRx pursuant to this Section 9.2,
         Roche Diagnostics shall have no further rights to the Device or the
         Know-How (as defined in the License Agreement in Sections 1.2 and 1.3,
         respectively), the Marketing License shall terminate and the
         Manufacturing License (if then granted) shall terminate, and all sums
         paid or payable shall remain the property of SpectRx and shall not be
         refundable, and to the extent accrued but unpaid any such sums owed to
         SpectRx shall thereupon be immediately due and payable. Termination of
         this Agreement by Roche Diagnostics pursuant to this Section 9.2 shall
         not constitute a termination of the Development Agreement nor the
         Marketing License granted thereunder. In the event of termination of
         this Agreement by Roche Diagnostics pursuant to this Section, Roche
         Diagnostics shall be deemed to have acquired the Manufacturing License
         described in the Development Agreement effective upon such termination,
         and provisions of Section 10 of this Agreement shall survive such
         termination.

10.0     PROVISIONS GOVERNING MANUFACTURING LICENSE

10.1     In the event Roche Diagnostics obtains the Manufacturing License in
         accordance with the terms and conditions set forth below or pursuant to
         Section 9.2, Roche Diagnostics shall have full, complete and
         unrestricted access to the Manufacturing Documentation. SpectRx agrees
         to provide all reasonable resources, as provided for in Section 10.2
         hereof, to render Roche Diagnostics fully qualified in all respects to
         supply Instruments with the same specifications, and manufacturing
         criteria and under the same regulatory and quality standards as if
         manufactured by SpectRx. Roche Diagnostics will receive from SpectRx a
         maximum of five hundred (500) hours of training at no cost and Roche
         Diagnostics will supply reasonably competent manufacturing and
         technical personnel who will be trained by SpectRx to support
         production of the Instrument.

10.2     The Manufacturing License shall issue only after the occurrence of a
         "Material Failure" (as defined below) by SpectRx to timely deliver
         Instruments purchased pursuant to Purchase Orders. "Material Failure"
         constitutes the failure by SpectRx to deliver upon or before the
         requested delivery dates therefor as specified in Purchase Orders: a)
         at least fifty percent (50%) of the Instruments that meet the
         Specification therefor (other than in immaterial respects) requested to
         be delivered within the first six (6) months of production, b) or at
         least seventy five (75%) of the Instruments that meet the Specification
         therefor requested to be delivered within the second six (6) months of
         production (the first twelve months of production beginning with the
         manufacture of the "period Two Instruments" (as


                                                                         Page 10
   11

         defined in Exhibit B to the Agreement) being the "Initial Manufacturing
         Period") after the Initial Manufacturing Period and c) at least ninety
         (90%) of the instruments that meet the specification therefor requested
         to be delivered after the Initial Manufacturing Period. For purposes of
         the foregoing, Instruments delivered on or prior to the requested
         delivery date therefor which are thereafter replaced or corrected on a
         timely basis pursuant to and in accordance with the provisions of
         Section 6.1 hereof shall be deemed to have been timely delivered in
         accordance with applicable Specification. Notwithstanding the
         foregoing, a Material Failure will not be deemed to have occurred by
         reason of the failure of SpectRx to deliver Instruments in quantities
         in any month during any six (6) month period in excess of the
         manufacturing capacity so stated in Section 2.5 hereof. Upon the
         occurrence of a Material Failure, should Roche Diagnostics give SpectRx
         written notice specifying such failure in reasonable detail, and should
         SpectRx not cure such Material Failure, within ninety (90) days of
         receipt of such notice, then upon a further written notice from Roche
         Diagnostics, and effective as of a date indicated therein, the
         Manufacturing License shall take effect and be deemed issued. Upon such
         issuance, SpectRx shall cooperate with Roche Diagnostics in a
         transition of manufacturing of the Instruments to Roche Diagnostics,
         the tooling and equipment then used in the manufacture of the
         Instruments shall be conveyed by SpectRx to Roche Diagnostics with
         Roche Diagnostics reimbursing SpectRx for its acquisition costs
         therefor (giving credit for the sum previously paid SpectRx by Roche
         Diagnostics pursuant to Section 4.2 hereof to the extent the tooling
         set forth on Exhibit D is transferred to Roche Diagnostics), and
         component parts and materials on hand or committed to be purchased by
         SpectRx be sold to Roche Diagnostics by SpectRx at SpectRx's cost.
         Subsequent to the issuance of the Manufacturing License, but no sooner
         than one (1) year from the issuance of the Manufacturing License,
         manufacturing of the Instruments may revert to SpectRx upon a
         demonstration in reasonable detail by SpectRx of its ability to resume
         manufacturing in conformance with the provisions of this Agreement
         accommodating Roche Diagnostics' volume requirements as to the
         Instruments and meeting the Specification, contingent upon full
         reimbursement by SpectRx to Roche Diagnostics of all reasonable costs
         and expenses associated with the issuance of the manufacturing license
         and subsequent commencement of manufacturing by Roche Diagnostics or a
         third party chosen by Roche Diagnostics. Should SpectRx make the
         showing necessary to cause the manufacturing to revert to SpectRx,
         Roche Diagnostics shall cooperate with SpectRx in the transition of
         manufacturing of the Instruments to SpectRx, the tooling and equipment
         then used in the manufacture of the Instruments shall be conveyed by
         Roche Diagnostics to SpectRx with SpectRx reimbursing Roche Diagnostics
         for its acquisition costs therefor (not including the sum paid SpectRx
         by Roche Diagnostics pursuant to Section 4.2 hereof to the extent the
         tooling set forth in Exhibit D is transferred to SpectRx, with
         ownership of such tooling to be maintained as set forth in Section 4.2
         hereof), component parts and materials on hand sold to SpectRx by Roche
         Diagnostics at its cost, and the provisions of this Agreement providing
         for the

                                                                         Page 11
   12

         purchase and supply of Instruments shall be deemed re-instituted and
         shall govern the parties accordingly. A "Material Failure" shall not
         include the inability of SpectRx to supply Instruments, which is the
         result of component supply interruptions which are caused without
         negligence on the part of SpectRx.


11.0     GENERAL PROVISIONS

11.1     The rights and obligations of Articles 6 (WARRANTIES), and 11 (GENERAL
         PROVISIONS) shall survive any termination of this Agreement and shall
         bind the parties and their legal representatives, successors and
         assigns. Neither party may assign this Agreement (except to an
         Affiliate) without the consent of the other, which consent shall not be
         unreasonably withheld.

11.2     SpectRx and Roche Diagnostics shall do all things necessary to comply
         with all applicable Federal, State and local laws, regulations and
         ordinances, including but not limited to the Regulations of the United
         States Department of Commerce relating to the export of Technical Data,
         insofar as they relate to the services to be performed under this

         approvals in the event of SpectRx export of Instruments manufactured
         for Roche Diagnostics Affiliates hereunder and for any technical data
         disclosed to SpectRx by Roche Diagnostics. SpectRx will not be the
         exporter of record for exports to Roche Diagnostic's customers. SpectRx
         will provide documentation that its facility and manufacturing process
         complies with FDA published guidelines and upon request by Roche
         Diagnostics demonstrate compliance.

11.3     Each of the parties hereto shall be excused from the performance of its
         obligations hereunder in the event such performance is prevented by
         force majeure and such excuse shall continue as long as the condition
         constituting such force majeure continues, plus fifteen (15) days after
         the termination of such condition. For purposes of this Agreement,
         force majeure is defined as follows: Causes beyond the control of
         SpectRx or Roche Diagnostics including, without limitation,
         regulations, laws or acts of any government, delays by exporting
         agency, destruction of production facilities or material by fire, or
         failure of public utilities or common carriers or embargo.

11.4     This Agreement, its appendices and the Development embody the entire
         understanding and agreement among the parties and supersede all
         previous negotiations, representations, writings and agreements,
         written or oral, with respect to the development and sale of the
         Instrument. This Agreement shall in no way preclude SpectRx or Roche
         Diagnostics (or any of their Affiliates) from entering into any
         agreements in the future which are not specifically limited or
         precluded hereunder.


                                                                         Page 12

11.6      Dispute Resolution

11.6.1    The parties shall attempt in good faith to resolve any dispute arising
          out of or relating to this agreement promptly by negotiations between
          representatives who have authority to settle the controversy. Either
          party may give the other party written notice of any dispute not
          resolved in the normal course of business. Within thirty days after
          delivery of such notice, representatives of both parties shall meet at
          a mutually acceptable time and place, and thereafter as often as they
          reasonably deem necessary, to exchange relevant information and to
          attempt to resolve the dispute. If the matter has not been resolved
          within sixty days of the disputing party's notice, or if the parties
          fail to meet within thirty days, either party may initiate mediation
          of the controversy or claim as provided in subparagraph (b) of this
          Section, unless the matter is governed by subparagraph (c) of this
          Section. All negotiations pursuant to this clause are confidential and
          shall be treated as compromise and settlement negotiations for
          purposes of the Federal Rules of Evidence and state rules of evidence.

11.6.2    If the dispute has not been resolved by negotiation and unless the
          dispute is concerning the matters described in and governed by
          subparagraph (c) below, then the parties shall endeavor to settle the
          dispute by mediation, non-binding arbitration, or other appropriate
          means for a period of at least sixty days before resorting to
          litigation. The procedures specified in this Section 10.6 must be
          followed before either party may seek judicial relief; provided,
          however, that a party may seek a preliminary injunction or other
          provisional judicial relief if in its judgment such action is
          necessary to avoid irreparable damage or to preserve


                                                                         Page 13
   14

          the status quo. Despite such action, the parties will continue to
          participate in good faith in the procedures specified in this Section
          10.6. All applicable statutes of limitation and defenses based upon
          the passage of time shall be tolled while the procedures specified
          in this Section 10.6 are pending, and the parties shall take such
          action, if any, required to effectuate such tolling.

11.6.3    Any dispute regarding the issuance of the Manufacturing License, and
          in particular the occurrence of any of the conditions listed in
          Section 10.2 hereof or in any way relating to the construction or
          interpretation of the rights or obligations of the parties thereunder
          or in respect thereof, which is not resolved through consultation as
          provided in subsection (11.6.1) of this Section, shall be resolved by
          an arbitration proceeding conducted in accordance with the following:

                  (i)      The arbitration proceeding shall be governed by the
                           rules of the American Arbitration Association
                           ("AAA"), and shall take place in Atlanta, Georgia;

                  (ii)     The arbitrator shall be qualified by education and
                           training to pass upon the particular matter to be
                           decided;

                  (iii)    There shall be one (1) arbitrator who shall be
                           selected in accordance with the procedures of AAA;

                  (iv)     The parties shall agree in advance as to the manner
                           in which the arbitrator shall promptly hear witnesses
                           and arguments, review documents and otherwise conduct
                           the arbitration proceedings. Both parties shall
                           receive notice of the subject of the arbitration and
                           the arbitration shall not be binding on the parties
                           with respect to any matters not specified in such
                           notice. Should the parties fail to reach an agreement
                           as to the conduct of such proceedings, the arbitrator
                           shall formulate his own procedural rules and promptly
                           commence the arbitration proceedings;

                  (v)      The arbitration proceedings shall be conducted as
                           expeditiously as possible with due consideration for
                           the complexity of the dispute in question. The
                           arbitrator shall issue its decision in writing (with
                           findings of fact and conclusions of law) within
                           twenty (20) days from the hearing of final arguments
                           by the parties;

                  (vi)     The arbitration award shall be given in writing and
                           shall be final and binding on the parties with
                           respect to the subject matter identified in the
                           notice called for by subsection (c)(iv) of this
                           Section, and not subject to any appeal and shall deal
                           with the question of costs of arbitration;

                  (vii)    Judgment upon the award may be entered in any court
                           having jurisdiction or, application may be made to
                           such court for a judicial recognition of the award or
                           an order of enforcement thereof, as the case may be;

                  (viii)   The parties shall not submit a dispute subject to
                           this subsection (b) of this Section to any federal,

                           of the arbitration panel, and if court proceedings to
                           stay litigation or compel arbitration under the
                           Federal Arbitration Act (Title 9, U.S.C.) or similar
                           state or foreign legislation are necessary, the party
                           who unsuccessfully opposes such proceedings shall pay
                           all associated costs, expenses and attorneys' fees
                           which are reasonably and actually incurred by the
                           other party;

                  (ix)     The parties shall keep confidential the arbitration
                           proceedings and the terms of any arbitration award,
                           except as may be otherwise required by law.

11.7     In the case of conflict between the general terms and conditions of a
         Roche Diagnostics issued purchase order, or of an SpectRx acceptance of
         a Roche Diagnostics purchase order, and this Agreement, the terms and
         conditions of this Agreement shall take precedence unless otherwise
         agreed in writing by the parties.

11.8     SpectRx shall make its records and facilities involved in the
         performance of this Agreement available to Roche Diagnostics personnel
         at reasonable and mutually convenient times during normal business
         hours for audit purposes and shall take any reasonable actions required

         design and the industrial design) of the Instrument for any other
         purpose (device, application, etc.) without the prior written consent
         of Roche Diagnostics. Roche Diagnostics acknowledges that SpectRx is
         under no restriction for the use of the design of the interior of the
         Instrument in any area outside of that licensed exclusively to Roche
         Diagnostics.

11.10    No modification, amendment, extension or waiver of this Agreement or
         any provision hereof shall be binding or effective unless in writing
         and signed by duly authorized representative of each of the parties.

         diabetes-screening instrument using the same or similar technology as
         employed in the Instrument other than with Roche Diagnostics or its
         Affiliate(s).

11.12    Further, SpectRx represents and warrants that it is under no
         obligation, nor will It assume any obligation, which would in any way
         interfere with or be inconsistent with or present a conflict or
         interest with the services to be furnished by SpectRx under this
         Agreement.

11.13    This Agreement shall be construed according to the laws of the State of
         Georgia. Venue for any litigation under this Agreement shall be state
         court, Gwinnett County, Georgia.



                                                                         Page 15

                                   Exhibit B

                                 Purchase Price


1.  The initial Instrument purchase prices shall be governed by the Volume Based
Production Cost Summary (attached hereto as Exhibit B-1) during the period from
initial product shipments until (i) Product Launch has occurred as defined in
Section 1.5 of the Development Agreement, (ii) the forecast from Roche
Diagnostics per Section 2.3 of the Supply Agreement equals or exceeds [*]
Instruments, and (iii) purchase orders issued by Roche Diagnostics for the
first [*] months of said forecast equals or exceeds [*] Instruments (the month
during which the latest to occur of (i), (ii), or (iii) above being referred to
herein as the "First Volume Pricing Month"). Instruments governed by this
Section 1 are collectively referred to as "Period One Instruments".

2.  The purchase price for the [*] Instruments beyond the Period One
Instruments purchased pursuant to this Supply Agreement shall be [*] per
Instrument. Such [*] Instruments are collectively referred to herein as the
"Period Two Instruments". The price set forth hereinabove for the Period Two
Instruments shall be adjusted in the same manner and same times as the
adjustments to the Unadjusted Maximum Prices as provided in, and using the
formulae set forth in, subparagraphs (i) and (ii) of Section 4 hereof.

3.     For all other Instruments delivered during or prior to the [*] month
succeeding the First Volume Pricing Month (i.e., other than Period Two
Instruments) and subject to the adjustments provided for in Section 6 hereof,
the price for such Instruments shall be computed and invoiced by SpectRx using
the Transfer Price Formula (as defined in Section 5 below) based on costs
constituting SpectRx's then current variable "run rate," measured over a
reasonable prior period, for each of the cost components comprising the
Transfer Price Formula (which will approximate SpectRx's actual costs relating
to such Instruments but may vary slightly due to timing). Notwithstanding the
foregoing, in no event shall the price for such Instruments exceed the Maximum
Price therefor, if any (as defined in Section 4 below). In computing the "run
rate" for its costs, SpectRx may in good faith make adjustments thereto to take
into account anticipated increases or decreases in such costs. When requested
by Roche Diagnostics, SpectRx will provide Roche Diagnostics with reasonable
documentation supporting its calculations, and promptly respond to further
reasonable inquiries by Roche Diagnostics for same. Instruments governed by
this Section 3 are collectively referred to as "Period Three Instruments".

4.     The maximum price for the Period Three Instruments shall be as follows:
       (a)  [*] per Instrument for the first [*] Period Three Instruments
            and for all further Period Three Instruments, if any, in excess of
            such [*] Instruments required to be delivered (or held for




                                                                    Page 2 of 6

     delivery) prior to the end of the [*] month succeeding the First Volume
     Pricing Month;

(b)  [*] for the next [*] Period Three Instruments beyond the Instruments
     described in subsection (a) and for all further Instruments, if any, in
     excess of such [*] Instruments required to be delivered (or held for
     delivery) during the [*] period succeeding the [*] period described in
     subsection (a); and

(c)  [*] for further Period Three Instruments beyond the Instruments described
     in subsection (b).

The prices set forth above in subsections (a), (b) and (c) are referred to
herein as the "Unadjusted Maximum Prices" and are subject to the following
adjustments:

     (i)  Commencing at the end of the [*] month succeeding the month of
          delivery of the first Instruments ordered by Roche Diagnostics
          pursuant to Section 2.4 of this Supply Agreement (such month being
          referred to herein as the "First Month"), the Unadjusted Maximum
          Prices shall be increased or decreased to give effect to any increase
          or decrease in the unit price for the [*] to be used in the
          Instrument as follows: The Unadjusted Maximum Price for any
          Instrument (or in respect of any lot of Instruments) shall be (i)
          increased by a number equal to a quotient, the numerator of which is
          the excess of the cost of the [*] installed in such Instrument (or in
          respect of any lot



                                                                    Page 3 of 6

   22
          of Instruments, the average cost of the [*] installed in such lot of
          Instruments) over [*] per [*], and the denominator is [*]; and (ii)
          decreased by a number equal to a quotient, the numerator is the excess
          of [*] per [*] over such cost and the denominator is [*].

     (ii) The Unadjusted Maximum Prices shall be adjusted for the [*] month
          period commencing at the end of the [*] month succeeding the First
          Month, and for each successive [*] period, on a proportionate basis,
          for changes in the [*] as such index changes during the prior [*]
          months.

     The price as determined by applying the foregoing adjustments to the
     applicable Unadjusted Maximum Price is referred to herein as the "Maximum
     Price."

5.   The Transfer Price Formula shall determine price as to Instruments, subject
     to adjustment as provided for in the immediately succeeding paragraph, on a
     per Instrument basis by adding (a) the sum of (i) material costs, (ii)
     direct assembly labor, (iii) packaging and labeling costs, (iv) cost of
     instruction manuals, (v) depreciation and amortization, and (vi) factory
     overhead attributable thereto, in each case using standard cost accounting
     measures; (b) an amount equal to such total under subsection (a), divided
     by [*], and then multiplied by [*] (so as



                                                                    Page 4 of 6

   23
     to represent a [*] margin in respect thereto); and (c) Georgia Tech
     Research Corporation royalties.

6.   The purchase price as computed pursuant to the Transfer Price Formula
     shall be subject to increase to add a further component in respect of
     improvement in costs, over current estimated costs, as follows: As costs
     are improved (after giving effect to costs required to implement cost
     improvement) so as to result in a price as calculated pursuant to the
     Transfer Price Formula which is lower than the Maximum Price therefor (or
     if there is no applicable Maximum Price, lower than the Maximum Price set
     forth in Section 4(c) hereof), then [*] of the purchase price impact of
     such cost improvement shall be added to the purchase price, although in no
     event shall the purchase price exceed the Maximum Price therefor, if
     applicable. The Maximum Prices referenced in the preceding sentence refer
     to the prices after giving effect to the adjustments thereto provided for
     in subparagraphs (i) and (ii) of Section 4 hereof.

7.   After the [*] month succeeding the First Volume Pricing Month,

           (a)   There shall no longer be a Maximum Price and the purchase
                 price for Instruments to be delivered thereafter shall be
                 calculated using the Transfer Price Formula.

           (b)   If the purchase price as so calculated pursuant to subsection
                 (a) above is less than or equal to the Maximum Price in effect
                 immediately prior to the end of the [*] period identified

                                                                     Page 5 of 6

     PORTIONS HAVE BEEN FILED SEPARATELY WITH THE COMMISSION.

   24
     above multiplied by [*] of such Maximum Price, then the purchase price as
     so calculated shall be the purchase price.

(c)  If the condition described in subsection (b) above is not met (i.e., the
     price is greater than the [*] benchmark), then the parties will meet, and,
     taking into account all relevant considerations, including the margins
     enjoyed by the parties during the term of the Supply Agreement to date,
     shall negotiate in good faith the purchase price for Instruments to be
     delivered subsequent to such 36th month. If the parties are unable to
     agree as to price, the matter will be referred to arbitration for
     resolution in accordance with the provisions of Section 11.6(c) of the
     Supply Agreement. The arbitrator shall be required to appoint a special
     master, with business experience concerning medical devices deemed
     relevant by the arbitrator, to assist and advise the arbitrator with the
     determination of the purchase price for the Instruments.

                                                                     Page 6 of 6

Exhibit F

SERVICE COMMITMENT:

         SpectRx, Inc. will provide a loaner diabetes screening instrument to
         the customer in the event of an Instrument failure during the first
         year warranty period, or during the warranty extension period. The
         customer's instrument will be returned to a SpectRx authorized service
         center for repair. Loaner instruments will be supplied by, and shall
         remain the property of SpectRx, for the following markets:
         United States, Canada, and the European communities.

PROCESS:

I.       ROCHE DIAGNOSTICS CORPORATION

         The initial one year warranty will commence on the date of installation
         as indicated on the installation report returned to the distributor or
         Roche Diagnostics. Roche Diagnostics will provide "First Line"
         telephone customer support in the United States, Canada, and the
         European community. SpectRx will supply a "First Line" troubleshooting
         guide, and train the Roche Diagnostics customer support personnel in
         it's use. This guide will be utilized for failure determination prior
         to requesting a loaner instrument be sent to the customer site under
         the loaner/warranty exchange program. Roche Diagnostics must obtain an
         RSA (Return Service Authorization) number from the SpectRx service
         center prior to shipment.

II.      INSTRUMENT REPAIR - SERVICE COMMITMENT - YEAR ONE

         Step 1 - Roche Diagnostics receives telephone call from the customer
         via a service/support "help" line. Customer support determines the
         failure using the "First Line" troubleshooting guide. Customer support
         then calls SpectRx to obtain an RSA number for a loaner Instrument. The
         loaner instrument is shipped by SpectRx to the customer within
         twenty-four (24) hours of receiving the call from Roche Customer
         support.

         Step 2 - The customer receives the loaner instrument and ships their
         defective instrument to SpectRx, utilizing the shipping container from
         the loaner.

                  NOTE: The shipping carton will be heavy duty and designed for
         ease of use with sufficient packing for safe shipment of the
         instruments. Included in the carton will be a supply of shipping
         instructions, documents, and labels for the customer's use.

         Step 3 - The instrument is received at the SpectRx authorized Service
         Center.





                                                                         Page 22
   30

         Step 4 - The instrument is repaired and checked for proper operation
         and readied for shipment back to the customer.

         Step 5 - The instrument is returned to the customer.

         Step 6 - The customer receives the repaired instrument and places it
         into operation. The SpectRx loaner instrument is packaged in the
         shipping carton and readied for shipment

         Step 7 - The customer ships the instrument back to SpectRx or to
         another specified location.

                  NOTE:  SpectRx will arrange and manage loaner instrument pick
                         up and delivery to/from the customer.

III.     SERVICE DEPOTS

         a)       The main Service Center at SpectRx will repair units using new
                  or good-as-new exchange parts with the goal of a one day
                  turnaround for the United States and Canadian markets.
