the Income and Lessee Deposits estimated by Assignor pursuant to Section 4(d)(i)
hereof to constitute part of the Transferred  Interest transferred (or deemed to
be transferred)  as of the Receivable  Effective Date, such Effective Time or as
of the Mop-Up Date.

               (c) First Effective Date; Mop-Up Date

               Each of Assignor and  Assignee  covenants  and agrees  that(i) if
each of the conditions precedent in Section 7(a)-(r) (as to Assignor) or Section
8(a)-(l) (as to Assignee) are satisfied or waived by the appropriate  party, the
first  Effective  Time with respect to any Aircraft  Transferred  Interest  will
occur on the Start Date and (ii) the Effective  Time for each and every Aircraft
Transferred Interest will occur not later than the close of business in New York
on the Mop-Up Date. Each of Assignor and Assignee  covenants and agrees that the
Receivable  Effective Date will occur no later than the sixth Business Day after
each of the conditions precedent in Subsection 7(s) through (v) (as to Assignor)
or  Subsection  8(m) through (o) (as to Assignee) are satisfied or waived by the
appropriate party. Each of Assignor and Assignee further agrees that at any time
after the earlier of (i) the seventh  Business Day after the Start Date and (ii)
the last Effective  Time to occur pursuant to the terms hereof,  (A) Assignor is
hereby authorized to withdraw from the Cash Account, an amount equal to the Cash
Amount less any  reduction of the Cash Amount  pursuant to the last  sentence of
this Section 4(c) or pursuant to Section 4(d)(ii) less one-half of the fees owed
to the Escrow Agent and (B) Assignee is hereby  authorized  to withdraw from the
Cash  Account  all other  funds in excess of the amount set forth in clause (A);
provided,  however,  if  Assignee  withdraws  the Cash  Amount  pursuant  to the
foregoing  clause (i) and there is a  subsequent  reduction  in the Cash  Amount
pursuant to the last sentence of this Section 4(c), then Assignor shall promptly
return to Assignee an amount equal to such subsequent reduction plus interest at
the  rate of 5.3%  per  annum  from  the  withdrawal  date  through  the date of
repayment  to  Assignee.  On the  Mop-Up  Date,  so long  as (i) the  conditions
precedent set forth in Section 7 hereof (other than with respect to the location
of the Aircraft) shall have been satisfied or waived by Assignor, Assignor shall
be obligated to deliver, with respect to each Aircraft Transferred Interest that
has not been assigned previously to Assignee (including any Aircraft Transferred
Interest which has not been transferred previously because the Aircraft relating
to such  Aircraft  Transferred  Interest has been the subject of a Loss of Title
but as to which such Loss of Title has been cured or  otherwise  corrected on or
prior to the Mop-Up Date), Assignment and Assumption Agreements, the evidence of
authorization described in Section 8(e)(iv), any consents referred to in Section
5.1(b),  the opinions  described in Section  8(i) and any other  instruments  or
documents  as  Assignee  or its counsel  shall  reasonably  request and (ii) the
conditions  precedent  set forth in Section 8 hereof (other than with respect to
the location of the Aircraft)  shall have been  satisfied or waived by Assignee,
Assignee  shall  be  obligated  to  deliver,   with  respect  to  each  Aircraft
Transferred   Interest  that  has  not  been  assigned  previously  to  Assignee
(including  any Aircraft  Transferred  Interest  which has not been  transferred
previously because the Aircraft relating to such Aircraft  Transferred  Interest
has been the subject of a Loss of Title but as

to which such Loss of Title has been cured or otherwise corrected on or prior to
the  Mop-Up  Date),  Assignment  and  Assumption  Agreements,  the  evidence  of
authorization  described in Section 7(j)(v), any consents referred to in Section
6.1(b),  the opinions  described in Section  7(m) and any other  instruments  or
documents as Assignor or its counsel shall reasonably  request. If on the Mop-Up
Date any of the conditions  precedent set forth in Section 7 or Section 8 hereof
(other than with respect to the location of the  Aircraft)  are not satisfied or
waived  by  the  applicable  party  with  respect  to any  Aircraft  Transferred
Interest,  any Aircraft which is subject of such Aircraft  Transferred  Interest
will no longer be the  subject  of this  Agreement  and this  Agreement  will be
deemed to be reformed to delete all  references  to such  Aircraft  and the such
Aircraft  Transferred  Interest  and the  Purchase  Price  will be reduced in an
amount equal to the Allocable  Portion  Percentage for such Aircraft and each of
the Note Amount and the Cash Amount as set forth on Schedule 4(a) hereof will be
adjusted on a pro rata basis.

               (d) Settlement of Income and Lessee Deposits

                   (i) Prior to assignment of a Transferred Interest to Assignee
here under, Assignor shall estimate the Income and any Lessee Deposits that have
been  received  by Assignor or the Owner  Trustee  relating to such  Transferred
Interest as of the  applicable  Effective  Time for such  Transferred  Interest.
Because the actual  amount of the Income and any Lessee  Deposits  relating to a
Transferred  Interest and received by Assignor or such Owner Trustee will not be
readily  determinable  until  after  the  applicable  Effective  Time,  a  final
calculation cannot be made on that date. Therefore, within fifteen (15) Business
Days after the end of the month in which such  Effective  Time occurs,  Assignor
shall provide Assignee with such final calculation (in reasonable detail) of the
Income and any Lessee  Deposits that have been received by Assignor or the Owner
Trustee  relating to such  Transferred  Interest.  To the extent the calculation
indicates  that the amounts  transferred  by Assignor  pursuant to Section  4(b)
hereof with respect to such  Transferred  Interest  were in excess of the actual
Income  and any  Lessee  Deposits  received  by  Assignor  or the Owner  Trustee
relating to such Transferred Interest, Assignee shall promptly pay the amount of
such  excess to Assignor  (plus  interest on such amount at the rate of 5.3% per
annum from the  applicable  date of payment to Assignee to the date of repayment
to  Assignor).  To  the  extent  the  calculation  indicates  that  the  amounts
transferred  by Assignor  pursuant to Section  4(b) hereof with  respect to such
Transferred  Interest were less than the actual  Income and any Lessee  Deposits
received by Assignor or the Owner Trustee relating to such Transferred Interest,
Assignor  shall  promptly pay the amount of such  deficiency  to Assignee  (plus
interest  on such  amount at the rate of 5.3% per annum  from the  Business  Day
following the applicable Effective Time to the date of payment to Assignee).  An
adjustment to the Purchase Price for Income under this Section  4(d)(i) shall be
treated  by the  parties  as a  purchase  price  adjustment  for all  income tax
purposes.

                   (ii) If at any time prior to the last Effective Time to occur
pursuant  to the terms  hereof,  any  Aircraft  which is subject of an  Aircraft
Transferred Interest not yet transferred by Assignor to Assignee suffers a Total
Loss,  such  Aircraft  will no longer be the subject of this  Agreement and this
Agreement  will be  deemed  to be  reformed  to delete  all  references  to such
Aircraft and the related Aircraft Transferred Interests; provided, however, that
with respect to any such Aircraft,  if such Total Loss is due to a Loss of Title
and if Assignor  cures or otherwise  corrects such Loss of Title by regaining or
recovering the use thereof or title thereto on or prior to the Mop-Up Date, such
Aircraft will be deemed to be reinstated and once more subject to this Agreement
and this  Agreement  will be deemed to be  reformed  to include  all  previously
deleted  references  to such  Aircraft  and  the  related  Aircraft  Transferred
Interests.  Contemporaneously with the removal of any Aircraft from the terms of
this  Agreement,  the  Purchase  Price will be reduced in an amount equal to the
Allocable  Portion  Percentage for such Aircraft and each of the Note Amount and
the Cash Amount as set forth on  Schedule  4(a) hereof will be adjusted on a pro
rata basis.  Contemporaneously  with the  reinstatement of an Aircraft into this
Agreement,  the  Purchase  Price  will be  increased  in an amount  equal to the
Allocable  Portion  Percentage for such Aircraft and each of the Note Amount and
the Cash Amount as set forth on  Schedule  4(a) hereof will be adjusted on a pro
rata basis. If at any time prior to the last Effective Time to occur pursuant to
the terms  hereof,  any  Aircraft  which is subject of an  Aircraft  Transferred
Interest not yet transferred by Assignor to Assignee suffers any property damage
or loss not  constituting  a Total Loss and such property  damage or loss is not
cured or corrected prior to the time when such Aircraft  Transferred Interest is
transferred  (or deemed to be  transferred)  by Assignor to  Assignee,  Assignor
shall pay to Assignee any insurance  proceeds  received by Assignor with respect
to such  property  damage or loss  promptly  after  receipt by  Assignor of such
insurance proceeds;  provided,  however,  that Assignor shall not enter into any
settlement of any insurance claim without the prior written consent of Assignee,
which consent may not be unreasonably withheld.

Reserved  Right and that such  facts and  circumstances  constitute  a  Reserved

               (a) Each party  agrees and  acknowledges  that from and after the
date hereof until the close of business on April 28, 1997, if Assignor  receives
a Superior Proposal,  Assignor may (i) furnish any information  requested by the
Offering Party with respect to such Superior  Proposal  (other than the contents
of this Agreement or any Ancillary Agreement),  (ii) participate in negotiations
with such Offering Party  regarding  such Superior  Proposal or (iii) enter into

Assignor  shall  require each  Offering  Party with whom it is still  engaged in

(i) determine  whether any such offer constitutes a Superior  Proposal,  (ii) if
there  is more  than one  Superior  Proposal,  select  which  Superior  Proposal
Assignor  intends to accept and (iii) provide written notice to Assignee setting
forth all the material terms and conditions of such selected  Superior  Proposal
("SP Notice").

               (c) After receipt of the SP Notice,  Assignee shall have five (5)

SECTION 12.    Further Assurances

               Each party agrees, upon the reasonable request of the other party
at any time and from time to time,  promptly  to execute  and  deliver  all such
further  documents  and promptly to take and forbear from all such action as may
be reason ably necessary or appropriate in order to more effectively  confirm or
carry out the provisions of this  Agreement or any of the Ancillary  Agreements,
including,  without  limitation,  the filing of any  Assignment  and  Assumption
Agreement  with the FAA pursuant to the Act or the CAA.  The parties  agree that

that any filings with the FAA or the CAA are merely ministerial in nature.

SECTION 13.    Taxes and Indemnities

               (a) Transfer Taxes

                   Assignee  hereby  covenants and agrees to pay (and  indemnify
and hold Assignor  harmless on an After-Tax Basis for) any and all registration,
docu ment or  filing  fees and any and all sales  taxes,  use taxes and  similar
transfer  taxes  (including,  without  limitation,  any  charges,  such as gross
receipts taxes (but excluding any taxes in the nature of any income tax) in lieu
thereof)  (collectively,  "Transfer  Taxes"),  that may be imposed in connection
with the sale,  assignment and transfer of any Transferred  Interests including,
without limitation,  any penalties, fines or interest thereon and those Transfer
Taxes relating to the transfer of rights and other  interests in and to, and the
act of  assuming  duties,  liabilities  and  obligations  in, to and under  this
Agreement, the Assignment and Assumption Agreements,  the Transferred Interests,
the Aircraft,  the  Operative  Agreements  or any of the  Receivable  Agreements
together with all reasonable and documented  out-of-pocket  costs,  expenses and
attorney's  fees incurred in  connection  therewith.  Assignor  hereby agrees to
perform such acts, including,  without limitation,  attending the closing of the
transactions  contemplated  hereby at a site or sites selected by Assignee,  and
executing  such  documents as may be reasonably  necessary to minimize  Transfer
Taxes.  The parties  further agree to furnish each other with such documents and
certificates  as they may reasonably  request in connection  with any claims for
exemption from the payment of Transfer Taxes.

the IRS of any written  proposed or final revenue agent's report,  30-day letter
or notice of deficiency in which an adjustment is proposed to the federal income
taxes of Assignor  for which any of the Lessees  would be required to  indemnify
Assignor under any Operative Agreement or any of the Receivable  Agreements and,
thereafter,  shall upon request keep  Assignee  apprised at least monthly of the
progress of any protest or proceeding in respect of such adjustment.

                   (ii) Assignee shall promptly  notify Assignor of receipt from
the IRS of any written  proposed or final revenue agent's report,  30-day letter
or notice of deficiency in which an adjustment is proposed to the federal income
taxes of Assignee  for which any of the Lessees  would be required to  indemnify
Assignee under any Operative Agreement and, thereafter,  shall upon request keep
Assignor  apprised at least monthly of the progress of any protest or proceeding
in respect of such adjustment.

               (c) Assignor's Indemnity

                   Assignor hereby  covenants and agrees upon demand of Assignee
to pay and assume liability for, and indemnify,  protect,  defend, save and keep
harmless  Assignee  and  each of its  Affiliates  and in each  such  case  their
respective   directors,   officers,   employees   and  agents   (the   "Assignee
Indemnitees"), on an After-Tax Basis, from and against any and all Damages which
may at any time or from time to time be imposed  upon,  incurred  by or asserted
against  any  of the  Assignee  Indemnitees  in any  way  relating  directly  or
indirectly  to,  or  arising  out  of,  (i)  any  inaccuracy  or  breach  of any
representation  or  warranty  made  by  Assignor  under  this  Agreement  or any
Ancillary Agreement to which it is a party, (ii) the ownership,  leasing, use or
operation of any Transferred  Interest prior to the Effective Time applicable to
such  Transferred  Interest  including,   without  limitation,  any  obligations
relating to the Trust  Estate,  any of the  Operative  Agreements  or any of the
Receivable  Agreements  relating to such  Transferred  Interest which arise from
acts,  omissions,  events or  circumstances  occurring or accruing  prior to the
Effective Time with respect to such Transferred Interest,  but not including any
Assumed Liabilities,  (iii) the failure of Assignor to perform or observe any of
its obligations under this Agreement or any Ancillary Agreement to which it is a
party,  (iv) any  litigation,  claim or action  brought by a limited  partner of
Assignor against any Assignee Indemnitee to the extent such litigation, claim or
action  directly arises out of and relates to the  transactions  contemplated by
this Agreement other than to the extent any litigation,  claim or action relates
directly  or  indirectly  to,  or arises  out of,  the  breach by such  Assignee
Indemnitee of the terms of this Agreement or any Ancillary  Agreement or (v) any
Liens set forth on Schedule 5(h) hereto; provided that (a) Assignor shall not be
liable for any Damages to the extent that  Assignee has a recovery  available to
it under any insurance  policy which was in effect on or prior to the applicable
Effective Time; (b) Assignor shall not be liable for any Damages attributable to
the gross  negligence or willful  misconduct of Assignee or its Affiliates;  and
(c)  Assignor  shall not be liable  for any  Damages  in excess of the  Purchase
Price. Notwithstanding the foregoing,  Assignor shall be liable pursuant to this
Section 13(c) only to the extent that the aggregate  cumulative Damages incurred
by the Assignee  Indemnitees  which are required to be  indemnified  by Assignor
exceed $50,000 (the "Threshold Amount") in which event, Assignor shall then also
be liable for the initial $50,000 of aggregate  cumulative  Damages  incurred by
the Assignee Indemnitees;  provided, that, with respect to any Lien set forth on
Schedule 5(h) hereto,  (x) the Threshold  Amount  limitation shall not apply and
Assignor shall be liable for all Damages arising from such Liens and (y) amounts
expended by Assignor to discharge  and release  such Liens shall not  constitute
Damages to be applied toward the Threshold  Amount and only those  expenses,  if
any,  actually incurred by Assignee in connection with such discharge or release
shall be so applied.

               (d) Assignee's Indemnity

                   Assignee hereby  covenants and agrees upon demand of Assignor
to pay and assume liability for, and indemnify,  protect,  defend, save and keep
harmless,  Assignor  and each of its  Affiliates  and in each  such  case  their
respective   directors,   officers,   employees   and  agents   (the   "Assignor
Indemnitees"), on an After-Tax Basis, from and against any and all Damages which
at any time or from time to time may be imposed  upon,  incurred  by or asserted
against the Assignor  Indemnitees in any way relating directly or indirectly to,
or  arising  out of,  (i) any  inaccuracy  or  breach of any  representation  or
warranty made by Assignee or any of its  Affiliates  under this Agreement or any
Ancillary  Agreement to which it or any of its  Affiliates is a party,  (ii) the
ownership, leasing, use or operation of any Transferred Interest on or after the
Effective  Time  applicable  to such  Transferred  Interest  including,  without
limitation,  any obligations  relating to the Trust Estate, any of the Operative
Agreements  or any of the  Receivable  Agreements  relating to such  Transferred
Interest which arise from acts, omissions,  events or circumstances occurring or
accruing  on or after  the  Effective  Time  with  respect  to such  Transferred
Interest,  (iii) the failure of Assignee or any of its  Affiliates to perform or
observe  any  of  their  respective  obligations  under  this  Agreement  or any
Ancillary  Agreement to which it or any of its  Affiliates is a party,  (iv) any
Assumed Liabilities or (v) any modification, amendment or other change to any of
the Operative  Agreements or any of the  Receivable  Agreements  entered into by
Assignee,  or to which Assignee  consents or forbears,  in any such case without
the prior  written  consent of Assignor  (such  consent  not to be  unreasonably
withheld) that affects any of the Reserved Rights; provided,  however, that with
respect to any Transferred Interest which includes a Lease, such indemnification
obligation shall only relate to modifications,  amendments or other changes made
or agreed to during the period  beginning on the  Effective  Date  applicable to
such Transferred Interest and ending on the date that is twenty-four (24) months
after the termination of the Lease included in such Transferred  Interest (which
period shall be deemed to include any renewals,  extensions or  continuations of

any Damages to the extent that Assignor has a recovery available to it under any

               (e) Survival of Representations and Warranties

                   All  representations  and  warranties  of the parties  hereto
contained in this Agreement (including all Schedules hereto) or in any document,
statement,  certificate or other  instrument  referred to herein or delivered at
the applicable  Effective Time in connection with the transactions  contemplated
hereby,  that (i) relate to any  Transferred  Interest  which  includes a Lease,
shall survive until the later of (A) twenty-four (24) months after the Effective
Time applicable to such Transferred Interest or (B) twelve (12) months after the
expiry of the Lease included in such  Transferred  Interest  (which period shall
not be deemed to include  any  renewals,  extensions  or  continuations  of such
Lease), (ii) relate to any Transferred  Interest which does not include a Lease,
shall survive until  twenty-four (24) months after the Effective Time applicable
to such Transferred Interest and (iii) do not relate to a Transferred  Interest,
shall survive until  twenty-four  (24) months after the first  Effective Time to
occur under this Agreement.


SECTION 14.    Indemnification Procedure

               (a)  Any  Assignee   Indemnitee  or  Assignor   Indemnitee   (the
"Indemnified Party") seeking  indemnification  hereunder shall give to the party
obligated under this Agreement to provide  indemnification  to such  Indemnified
Party (the  "Indemnitor")  a notice  ("Claim  Notice")  describing in reasonable
detail the facts  giving rise to its claim for  indemnification  hereunder,  and
shall  include  in such  Claim  Notice  (if then  known) the amount or method of
computation of the amount of the claim, and a reference to the provision of this
Agreement or any other agreement,  document or instrument executed and delivered
hereunder or in  connection  herewith  upon which such claim is based;  provided
that a Claim Notice in respect of any action at law or suit in equity against an
Indemnified Party by a third party, as to which  indemnification  will be sought
(a "Third Party  Action"),  shall be given  promptly after the action or suit is
commenced;  provided, further, that failure of the Indemnified Party to give the
Indemnitor  prompt  notice in respect of any such Third Party Action as provided
herein shall not relieve the Indemnitor of its obligations hereunder,  except to
the  extent  such  Indemnitor  shall  have been  materially  prejudiced  by such
failure.

               (b) The  Indemnitor  shall be  entitled  (but not  obligated)  to
assume the defense or settlement  of such Third Party Action,  or to conduct any
negotiations  or  proceedings  to settle or otherwise  eliminate any Third Party
Claim  and shall  pay the  reasonable  fees and  disbursements  of such  counsel
related to such Third Party Action.  If the Indemnitor  assumes any such defense
or settlement or any such negotiations, it shall pursue such defense, settlement
or  negotiations  in good  faith.  If the  Indemnitor  fails to elect in writing
within 30  Business  Days of the  notification  referred to above to assume such
defense, the Indemnified Party may engage counsel to defend, settle or otherwise



                                       38


<PAGE>



dispose  of such  action  or  proceeding,  which  counsel  shall  be  reasonably
satisfactory to the Indemnitor.  In any such Third Party Action, any Indemnified
Party shall have the right to retain its own counsel,  but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party unless (i) the
Indemnitor and the Indemnified Party shall have mutually agreed to the retention
of such counsel or (ii) the named parties to any such proceeding  (including any
impleaded  parties)  include both the Indemnitor and the  Indemnified  Party and
representation  of both the  Indemnitor  and the  Indemnified  Party by the same
counsel would be inappropriate  due to actual or potential  differing  interests
between them. It is understood that the Indemnitor shall not, in connection with
any Third Party Action or related  Third Party Action in the same  jurisdiction,
be liable for the fees and expenses of more than one separate  firm (in addition
to local  counsel)  for all  Persons to be  indemnified  pursuant to Section 13;
provided that the Indemnitor will be so liable if (x) the Indemnified  Party has
reasonably  concluded that there may be legal  defenses  available to it in such
Third Party Action that are different from or in addition to those  available to
the  Indemnitor  or (y) a conflict  or  potential  conflict  exists  between the
Indemnified  Party and the  Indemnitor in such Third Party Action (in which case
the Indemnitor will not have the right to direct the defense of such Third Party
Action with respect to which such conflict  exists on behalf of the  Indemnified
Party), but only to the extent such fees and expenses are incurred in connection
with such  conflicting  issues.  Any such  separate  firm shall be designated in
writing by the  Indemnified  Party.  The Indemnitor  shall not be liable for any
settlement  of any  proceeding of such Third Party Action  effected  without its
written  consent,  but if the Indemnitor  consents to any such  settlement,  the
Indemnitor  agrees to indemnify the Indemnified  Party from and against any loss
or liability for which  indemnity is available  hereunder and which is specified
in such settlement or judgment.  No Indemnitor shall,  without the prior written
consent  of the  Indemnified  Party  (which  consent  shall not be  unreasonably
withheld  or  delayed),  effect any  settlement  of any  pending  or  threatened
proceeding  in  respect of which any  Indemnified  Party is or could have been a
party and indemnity could have been sought hereunder by such Indemnified  Party,
unless such settlement  includes an  unconditional  release of such  Indemnified
Party  from  all  liability  or  claims  that  are the  subject  matter  of such
proceeding and such settlement only involves the payment of money.

               (c) Assignor  shall be entitled in all cases (but not  obligated)
to assume the  settlement and to conduct  negotiations  or proceedings to obtain
the  discharge  and  release  of or  otherwise  eliminate  any Lien set forth on
Schedule  5(h)  hereto.  If  Assignor  assumes any such  settlement  or any such
negotiations,  it shall pursue such  settlement or  negotiations  in good faith.
Assignor  shall not be liable for any  settlement  or discharge of any such Lien
effected  without its  written  consent,  but if  Assignor  consents to any such
settlement or discharge,  Assignor agrees to indemnify Assignee from and against
any loss or liability  for which  indemnity is available  hereunder and which is
specified in such settlement or discharge.

               (b) by either  party by written  notice to the other party if the
transactions  contemplated  hereby  have not been  consummated  on or before the
Outside Date;  provided,  however,  that the right to terminate  this  Agreement
under this Section  15(b) shall not be  available to any party whose  failure to
fulfill any of its obligations under this Agreement has been the cause of or has
resulted  in  the  failure  of  the  transactions   contemplated   hereby  being
consummated on or before the Outside Date; or

               (c) by (i) Assignor if (a) Assignor  accepts or recommends one or
more  Superior  Proposals  to its  partners  or  resolves  to do  either  of the
foregoing and (b) Assignee no longer has the right  pursuant to Section 11(c) to
deliver an  Assignee  Acceptance  Notice to  Assignor or (ii) by Assignee if (x)
Assignor has given an SP Notice and (y) at least  fourteen (14) days have passed
since the date on which Assignee's right pursuant to Section 11(c) to deliver an
Assignee Acceptance Notice terminated.

or about April 18, 1997, an action  entitled Equity  Resources,  Inc. v. Polaris
Investment  Management  Corporation,  et al. was filed in the Superior Court for
the County of Middlesex, Commonwealth of Massachusetts. The complaint names each
of Polaris Investment Management  Corporation,  Polaris Aircraft Income Fund II,
Polaris  Aircraft  Income Fund III,  Polaris  Aircraft  Income Fund IV,  Polaris
Aircraft Income Fund V, and Polaris Aircraft Income Fund VI, as defendants.  The
complaint alleges that Polaris  Investment  Management  Corporation,  as general
partner of each of the partnerships, committed a breach of its fiduciary duties,
violated  applicable  partnership  law  statutory  requirements,   and  breached
provisions of the partnership  agreements of each of the foregoing  partnerships
by  failing  to  solicit  a  vote  of the  limited  partners  in  each  of  such
partnerships in connection  with the proposed sale of the Transferred  Interests
to  Assignee  and in  failing  to  disclose  material  facts  relating  to  such
transaction.  Plaintiffs  filed a  motion  seeking  to  enjoin  the  sale of the
Transferred  Interests to Assignee,  which motion was denied by the Court on May
6, 1997.  Plaintiffs  have filed an appeal from the order  denying their request
for an injunction.
