Item 5. Other Events.

Overview

     NOXSO Corporation ("NOXSO"),  which is currently reorganizing under Chapter
11 of the U. S.  Bankruptcy  Code, has identified two principal  elements in its
plan to emerge from bankruptcy: the sale of its liquid sulfur dioxide production
facility  located  in  Charleston,  Tennessee  (the  "Tennessee  Facility")  and
organizing a project for the commercial  demonstration of the NOXSO Process. The
NOXSO Process is an advanced flue-gas treatment  technology that  simultaneously
removes  pollutants  (sulfur  dioxide (SO2) and nitrogen oxides (NOx)) linked to
both acid rain and ground  level  ozone from flue gas  generated  by  coal-fired
boilers.  The removed SO2 is converted into a saleable  sulfur  by-product;  the
removed NOx is converted to nitrogen and oxygen and released to the atmosphere.

Completion of Sale of Tennessee Facility

     On December 31, 1997,  NOXSO completed the sale of the Tennessee  Facility,
which does not utilize the NOXSO Process,  to an affiliate of Republic Financial
Corporation for $11 million.

     Approximately  $9 million of the  proceeds  from the sale of the  Tennessee
Facility  have been used to retire claims of creditors of NOXSO holding liens on
the Tennessee  Facility and to pay administrative  expenses.  In connection with
the closing of the sale of the  Tennessee  Facility and the  application  of the
proceeds thereof, the claims of Olin Corporation and Praxair Corporation against
NOXSO have been extinguished, and the litigation between Olin and NOXSO has been
terminated. Various claims made against NOXSO in the bankruptcy proceeding which
were not secured by the Tennessee  Facility remain  outstanding  and, except for
post-petition  claims, it is unlikely that a substantial portion of these claims
will  be paid  with  the  remaining  proceeds  from  the  sale of the  Tennessee
Facility.  NOXSO is in the  process of  evaluating  such  claims  and  currently
expects  to file  objections  in the  bankruptcy  proceedings  to a  significant
portion of such claims.

     NOXSO will use a portion  of the  remaining  proceeds  from the sale of the
Tennessee  Facility to pay its  operating  expenses  while it  continues  in its
efforts to emerge from  bankruptcy,  including,  in  particular,  obtaining  the
funding and approvals needed to build and operate a commercial  demonstration of
the NOXSO Process pursuant to the Host Site Agreement discussed below.

Execution of Host Site Agreement

     On January  5, 1998,  NOXSO  signed a Host Site  Agreement  (the "Host Site
Agreement")  with  Richmond  Power & Light  ("RPL")  to  demonstrate  the  first
commercial-sized  installation of the NOXSO Process.  RPL is a municipally owned
electric generation and transmission organization serving the Richmond,  Indiana
area.  The NOXSO plant will be constructed  at RPL's  Whitewater  Valley Station
located  in  Richmond,  Indiana,  and  will  treat  all of the  flue  gas from a
33-megawatt electric generating unit.

                                        1

<PAGE>



     With execution of the Host Site Agreement,  NOXSO is requesting approval by
the U.S.  Department of Energy ("DOE") of the new project site and funding plan.
DOE had  previously  approved  funding  for a similar  installation  at an Alcoa
facility in Indiana, a project that was terminated prior to construction. If DOE
approval  is  obtained,  this  project  would be part of the  DOE's  Clean  Coal
Technology Program that provides up to 50% project funding.

     The  design,   construction  and  two-year  demonstration  is  budgeted  at
approximately  $28 million.  In addition to DOE and RPL, outside funding will be
requested by NOXSO and RPL from research organizations, state agencies and other
interested parties.  NOXSO will seek to secure  approximately $10 to $12 million
to complete the financing  package  through a  combination  of new equity and/or
debt plus the aforementioned  outside funding. In addition to DOE approval and a
complete financing package, other conditions that must be met for the project to
proceed  with  detailed   engineering   and   construction   include   obtaining
environmental and construction permits.

     Subject  to  satisfying   all   conditions,   construction   of  the  NOXSO
installation  at RPL is scheduled to begin in the spring of 1999 with startup in
the spring of 2000.

     If the project proceeds through the start-up phase, the Host Site Agreement
provides  that,  during a  two-year  demonstration  period  (the  "Demonstration
Period"),  NOXSO will own all SO2 allowances ("SO2  Allowances"),  and NOXSO and
RPL will each own one half of the NOx allowances,  ("NOx  Allowances"),  if any,
generated by the operation of the plant with the facilities for the operation of
the NOXSO Process (the "Project  Facilities")  as compared to those generated by
the operation of the plant without such facilities. NOXSO also has the option to
receive  from RPL the cash  value of such  Allowances.  Under the SO2  Allowance
program established under the federal Clean Air Act, each generator receives SO2
Allowances at the beginning of each year, which, when used, allow it to generate
one ton of SO2 emissions  during the year of use. To the extent a generator does
not  expend  such SO2  Allowances  in a year,  they can be  banked.  Banked  SO2
Allowances  can be applied to future use,  thus  enabling  facilities to execute
their  compliance  and  allowance   strategies  according  to  individual  plant
reduction  requirements,  system-wide  planning cycles, and  pollutant-reduction
requirements throughout their entire system. SO2 Allowances can also be sold for
use by others to enable  them to emit SO2.  The EPA has not  adopted a  national
program  for NOx  Allowances  similar  to the SO2  Allowances  program,  but has
recommended,  in proposed  regulations  under Title I of the Clean Air Act, that
states  adopt NOx  Allowance  programs.  While  certain  states have adopted NOx
Allowance programs, Indiana has not to date adopted such a program.

     At the end of the Demonstration  Period, or upon the earlier termination of
the Host Site  Agreement  in  accordance  with its terms,  NOXSO is obligated to
remove the  Project  Facilities.  In lieu of  requiring  removal of the  Project
Facilities  at the  end of the  Demonstration  Period,  RPL has  the  option  to
purchase the Project Facilities at an agreed-upon price.

Additional Debtor-in-Possession Financing

     On December 16, 1997, the Bankruptcy Court entered an order authorizing the
Company to obtain up to $100,000 of  debtor-in-possession  financing in addition
to the  $650,000 of  debtor-in-possession  financing  that had  previously  been
approved and obtained. Under the December 1997 arrangement, the Company borrowed
$90,000,  which was repaid when the Tennessee  Facility was sold,  together with
interest equal to 1% of the principal amount loaned.  The loans were made to the
Company as  follows:  $32,500  from Robert M. Long,  a director of the  Company;
$10,000 from John  Toedtman,  a director of the  Company;  $22,500 from Edwin J.
Kilpela,  the Chief Executive Officer and a director of the Company; and $25,000
from a financial  advisor to the Company.  In  connection  with the loans and as
authorized by the Bankruptcy  Court,  the Company issued one share of its Common
Stock for each $3.00 of principal loaned to the Company.  Mr. Kilpela waived any
right he had to receive  such shares.  As a result,  the Company  issued  22,500
shares of its Common Stock in connection with the financing.  After the issuance
of those shares,  the total number of shares of Common Stock outstanding  (which
was  incorrectly  stated on the cover page of the Company's  Report on Form 10-Q
for the quarter ended September 30, 1997) was 15,022,151.

Plan of Reorganization

     Pursuant to an order of the  Bankruptcy  Court for the Eastern  District of
Tennessee  dated  January 6, 1998,  NOXSO has been  granted an  extension of its
exclusive  time to file a plan of  reorganization  until  February 15, 1998. The
order will become final unless  objections  are filed within 20 days of the date
of the order.

Project Funding Needs

     The  completion of the sale of the Tennessee  Facility and the execution of
the Host Site  Agreement  represent  the  completion  of one of the  elements of
NOXSO's  plan to emerge  from  bankruptcy  and a  significant  step  toward  the
completion  of the  second  element,  that  is,  organizing  a  project  for the
commercial  demonstration  of the NOXSO Process.  However,  in order to complete
such a commercial  demonstration,  NOXSO must,  among other  things,  obtain the
consent of the DOE to utilize DOE funding at the new  project  site,  as well as
raise $10 million to $12 million in additional equity and/or debt financing.  No
source has been identified for such additional financing.  If NOXSO is unable to
accomplish these objectives, it may be necessary for NOXSO to sell the rights to
the NOXSO Process in the bankruptcy proceedings and to liquidate. In such event,
it  is  unlikely  that  sufficient   funds  will  be  generated  to  permit  any
distribution to be made to NOXSO's stockholders.

ARTICLE 2. PROJECT OVERVIEW.

     2.1 Intent.  The  provisions of this Article 2 are intended to be a general
introduction  to this  Agreement and are not intended to expand the scope of the
Parties'  respective  obligations  under  this  Agreement  or to alter the plain
meaning of the terms and conditions of this  Agreement.  However,  to the extent
the  terms  and  conditions  of  this  Agreement  do not  address  a  particular
circumstance  or are otherwise  unclear or ambiguous,  such terms and conditions
are to be  interpreted  and construed so as to give effect to the  provisions of
this Article 2.

     2.2 Project  Overview.  The Parties  hereto agree that the  following is an
accurate summary of their overall goals and objectives under this Agreement:

          2.2.1 The primary  goal of this  Agreement  is to design,  build,  and
     operate  facilities at RPL's  Whitewater  Valley Station for the successful
     demonstration of the NOXSO Process.

          2.2.2 Upon  satisfactory  completion of the  conditions  precedent set
     forth in this Agreement,  construction  of the Project  Facilities at RPL's
     Whitewater  Valley  Station  will  commence  in  accordance  with plans and
     specifications to be approved by the Parties.

          2.2.3 With respect to construction  and  demonstration  of the Project
     Facilities,  RPL will (a) provide the site for construction of the Project,
     (b) grant  NOXSO a license for the site during the period it is required to
     construct and operate the Project  hereunder and to the extent  required to
     remove the  Project if and as  required  hereby,  (c) obtain all  necessary
     federal, state, and municipal permits required for construction, (d) unless
     provided  by  NOXSO,   design,   supply  and   construct  a  "baghouse"  to

     that the other Party (the "Disclosing Party") has disclosed or may disclose
     information  relating to the conduct under this  Agreement  such as (a) RPL
     Information,  with respect to  disclosures  by RPL, (b) NOXSO  Information,
     with  respect  to  disclosures  by  NOXSO,   and/or  (c)  with  respect  to
     disclosures by either Party, information relating to the Disclosing Party's

          materials of equal or equivalent import;

               6.1.2.2  Not  to  divulge  any  Proprietary  Information  or  any
          information  derived therefrom to any third person (except consultants

          below); and

          Agreement.

               6.1.2.4  Any  consultant,  contractor,  agent or  customer  given
          access to any such  Proprietary  Information  must  have a  legitimate

          writing.

          6.1.3  Without  granting any right or license,  the  Disclosing  Party
     agrees that the foregoing  Subsections  6.1.2.1  through  6.1.2.3 shall not
     apply with respect to any  information  after five (5) years  following the
     expiration  or  termination  of  this  Agreement  or  with  respect  to any
     information that the Receiving Party can document (i) is generally known to
     the public through no improper  action or inaction by the Receiving  Party,
     or any agent, consultant,  contractor,  or employee of the Receiving Party,
     (ii)  was in the  Receiving  Party's  possession  or  known  by it prior to
     receipt from the Disclosing  Party,  (iii) was rightfully  disclosed to the
     Receiving Party by a third party, (iv) was  independently  developed by the
     Receiving Party without the use or benefit of any  Proprietary  Information
     of the  Disclosing  Party,  or (v) is required by law or  regulation  to be
     disclosed  to a third  party,  subject to the  requirements  of  Subsection
     6.1.4, below.

          6.1.4  The   Receiving   Party  may  make   disclosures   required  by
     governmental  or court order provided the Receiving  Party uses  reasonable
     efforts  to  limit  disclosure  and  obtain  confidential  treatment  or  a
     protective  order,  and has allowed the Disclosing  Party to participate in
     the proceeding.

          6.1.5  Immediately  upon  termination or expiration of this Agreement,
     the Receiving Party will turn over to the Disclosing  Party all Proprietary
     Information  of the  Disclosing  Party and any and all  copies or  extracts
     thereof,  except  that the  Receiving  Party may retain one (1) copy of all
     Proprietary Information in a confidential file in the office of its General
     Counsel or its Legal Services  Department (as the case may be) for archival
     legal purposes only.

          6.1.6 The Receiving  Party  acknowledges  and agrees that,  due to the
     unique nature of the Disclosing Party's Proprietary Information,  there can
     be no adequate remedy at law for any breach of its  obligations  hereunder,
     that any such  breach  may allow the  Receiving  Party or third  parties to
     unfairly compete with the Disclosing Party resulting in irreparable harm to
     the  Disclosing  Party,  and  therefore,  that upon any such  breach or any
     threat  thereof,  the  Disclosing  Party shall be  entitled to  appropriate
     equitable relief in addition to whatever remedies it might have at law. The
     Receiving  Party will notify the  Disclosing  Party in writing  immediately
     upon the  occurrence  of any such  unauthorized  release or other breach of
     which it is aware.

     6.2 Terms of Agreement.  Except to the extent  otherwise  expressly  agreed
upon  by  the  Parties,  or  as  required  to  fulfill  legal,  regulatory,   or
governmental  requirements,  the terms and conditions of this Agreement, and any
amendments or addenda thereto,  shall be considered  Proprietary  Information of
both  RPL  and  NOXSO  and  will  be  accorded  the  same  protections  accorded
Proprietary Information pursuant to Subsection 6.1.2.

     6.3 Public  Disclosures and Press  Releases.  The Parties will consult with
each other and,  if  required,  the DOE,  before  issuing  any press  release or
otherwise  making any public  statement  with respect to the matters  covered by
this  Agreement,  and shall not issue any such  press  release  or make any such
public statement prior to such consultation, except as may be required by law. A
Party  will not issue a public  statement  or press  release  which  includes  a
reference to the other Party  without the agreement of the other Party except as
may be  required by law. In the event that  disclosure  is required by law,  the
Party required to disclose such  information will use its best efforts to inform
the other  Party  with as much  advance  notice as  possible  as to the  nature,
manner, and time of the disclosure.

ARTICLE 10. FORCE MAJEURE.

     10.1  Definition.  Force majeure,  as used herein,  means war,  revolution,
invasion,  insurrection,  civil disorders, acts of God, compliance with any law,
regulation,  or  order of the  United  States  or any  state  government  or any
subdivision or agency of any of them, and any other  conditions or circumstances
of a similar nature.

     10.2 Excusing Delay. When performance hereunder is delayed by force majeure
for any other reason during the Demonstration  Period,  the time period for such
performance  shall be extended  by the period of delay so caused.  The Period of
Commercial  Operation shall not, however,  be extended by reason of this Article
or otherwise.  Contractual action taken by the DOE as a result of any such delay
shall not itself be considered an event of force majeure.

     10.3  Procedure.  The Party affected by force majeure shall promptly notify
the other Party in writing,  stating the cause and, insofar as foreseeable,  the
likely effect.  Similarly, such Party shall promptly notify the other Party upon

ARTICLE 11. TERMINATION

     11.1  Termination by RPL Prior to Commencement of Stage 2. At the option of
RPL after December 31, 1998, RPL may by notice to NOXSO terminate this Agreement
prior to  commencement  of Stage 2 if any of the conditions set forth in Section
9.1 have not been satisfied or revised.

     11.2  Termination by NOXSO Prior to  Commencement of Stage 2. At the option
of NOXSO after  December 31,  1998,  NOXSO may by notice to RPL  terminate  this

     11.3 Default by NOXSO.  RPL may by written  notice to NOXSO  terminate this
Agreement, immediately in any of the following events:

          11.3.1 Material non-monetary breach of this Agreement by NOXSO that is
     not  remedied  by NOXSO  within  ninety  (90) days  after the date of RPL's

                                       21

<PAGE>



     such  longer  period  as is  required  to cure the  breach  provided  NOXSO
     commences  such cure  within  said  ninety  (90) day period and  thereafter
     diligently prosecutes it); or

          11.3.2 Any  failure  by NOXSO to make a payment  called for in Section

     notice from RPL stating the delinquency.

     11.4  Termination at NOXSO's  Option.  NOXSO may, by prior written  notice,
terminate  this Agreement if, for reasons  beyond  NOXSO's  control,  there is a
serious  economic  failure of the NOXSO  Process  and the  solvency  of NOXSO is
imminently  threatened.  In the  case of such  termination,  the  provisions  of
Section 11.5 below shall apply.

     11.5  Settlements  Upon  Termination  by RPL. If upon the effective date of
termination  of this  Agreement  by RPL under  Section  11.2,  or by NOXSO under
Section 11.4.1,  any part of the Project  Facilities is in place, RPL may retain
it and  operate it,  including  bringing it into  operating  condition,  without
further  obligation to NOXSO,  or RPL may require NOXSO to remove it and restore
the Site to its condition prior to activity  hereunder.  Subsection  7.1.1 shall
continue  to the  benefit of RPL in the event and to the extent that RPL retains
all or part of the  Project  Facilities.  If for any reason  this  Agreement  is
terminated  before the end of the  Demonstration  Periods  and RPL  retains  and
operates the Project Facility,  RPL agrees to provide DOE with all technical and
economic data related to the design,  construction  and operation of the Project
