         GUARANTY,  dated as of January 28, 1999, by and among THE MORGAN GROUP,
INC.,  a  Delaware  corporation  ("Group"),  MDA  CORP.,  an Oregon  corporation
("MDA"),  and  TRANSPORT  SERVICES  UNLIMITED,   INC.,  an  Indiana  corporation
("Transportation"  and,  collectively  with Group and MDA, the "Guarantors" and,
each individually,  a "Guarantor") in favor of (a) BANKBOSTON,  N.A., a national
banking association,  as agent (hereinafter,  in such capacity, the "Agent") for
itself  and the  other  banking  institutions  (hereinafter,  collectively,  the
"Banks")  which are or may become  parties to a  Revolving  Credit and Term Loan
Agreement  dated as of January  28,  1999 (as amended and in effect from time to
time,  the  "Credit  Agreement"),  among  Morgan  Drive  Away,  Inc.,  a Indiana
corporation  ("Morgan"),  TDI, Inc., an Indiana corporation  ("TDI"), and Morgan
Finance,  Inc., an Indiana corporation  ("Finance" and, collectively with Morgan
and TDI, the "Companies" and, each individually, a "Company"),  Group, the Banks
and the Agent and (b) each of the Banks.

         WHEREAS,  the  Companies and the  Guarantors  are members of a group of
related  corporations,  the success of any one of which is  dependent in part on
the success of the other members of such group;

         WHEREAS,  each  Guarantor  expects  to receive  substantial  direct and
indirect  benefits  from the  extensions of credit to the Companies by the Banks
pursuant to the Credit Agreement (which benefits are hereby acknowledged);

         WHEREAS,  it is a condition precedent to the Banks' making any loans or
otherwise extending credit to the Companies under the Credit Agreement that each
of the Guarantors execute and deliver to the Agent, for the benefit of the Banks
and the Agent, a guaranty substantially in the form hereof; and

         WHEREAS,  each Guarantor wishes to guaranty the Companies'  obligations
to the  Banks and the Agent  under or in  respect  of the  Credit  Agreement  as
provided herein;

         NOW, THEREFORE, each of the Guarantors hereby agrees with the Banks and
the Agent as follows:

         1.  Definitions.
         The term  "Obligations"  and all other  capitalized  terms used  herein
without  definition shall have the respective  meanings provided therefor in the
Credit Agreement.

         2.  Guaranty of Payment and Performance.  Each of
         the  Guarantors  hereby  guarantees to the Banks and the Agent the full
and  punctual  payment  when  due  (whether  at  stated  maturity,  by  required
pre-payment, by acceleration or otherwise), as well




                                                  -2-


as the  performance,  of all of the  Obligations  including all such which would
become due but for the operation of the automatic  stay pursuant to ss.362(a) of
the Federal  Bankruptcy Code and the operation of ss.ss.502(b) and 506(b) of the
Federal  Bankruptcy  Code.  This  Guaranty  is an  absolute,  unconditional  and
continuing  guaranty of the full and punctual  payment and performance of all of
the  Obligations  and  not  of  their  collectibility  only  and  is in  no  way
conditioned  upon any  requirement  that the Agent or any Bank first  attempt to
collect any of the  Obligations  from the Companies or resort to any  collateral
security or other means of obtaining  payment.  Should the Companies  default in
the payment or performance  of any of the  Obligations,  the  obligations of the
Guarantors  hereunder with respect to such  Obligations  in default shall,  upon
demand by the Agent,  become  immediately due and payable to the Agent,  for the
benefit of the Banks and the Agent,  without demand or notice of any nature, all
of  which  are  expressly  waived  by each of the  Guarantors.  Payments  by the
Guarantors  hereunder  may be required by the Agent on any number of  occasions.
All  payments by the  Guarantors  hereunder  shall be made to the Agent,  in the
manner and at the place of payment  specified  therefor in the Credit Agreement,
for the account of the Banks and the Agent.

         3.  Guarantors' Agreement to Pay Enforcement Costs, etc.
         Each of the Guarantors further agrees, as the principal obligor and not
as a guarantor  only, to pay to the Agent, on demand,  all reasonable  costs and
expenses  (including court costs and legal expenses) incurred or expended by the
Agent or any Bank in  connection  with the  Obligations,  this  Guaranty and the
enforcement  thereof,  together with interest on amounts  recoverable under this
ss.3 from the time when such amounts become due until payment, whether before or
after judgment,  at the rate of interest for overdue  principal set forth in the
Credit  Agreement,  provided  that if such interest  exceeds the maximum  amount
permitted to be paid under  applicable  law, then such interest shall be reduced
to such maximum permitted amount.

         4.  Waivers by Guarantors; Bank's Freedom to Act.
         Each of the  Guarantors  agrees that the  Obligations  will be paid and
performed strictly in accordance with their respective terms,  regardless of any
law,  regulation  or  order  now or  hereafter  in  effect  in any  jurisdiction
affecting  any of such terms or the rights of the Agent or any Bank with respect
thereto.  Each of the Guarantors  waives  promptness,  diligences,  presentment,
demand,  protest,  notice of acceptance,  notice of any Obligations incurred and
all other notices of any kind,  all defenses which may be available by virtue of
any  valuation,  stay,  moratorium  law or other similar law now or hereafter in
effect,  any right to require the  marshalling of assets of the Companies or any
other entity or other person primarily or secondarily liable with respect to any
of the Obligations,  and all suretyship defenses generally. Without limiting the
generality of the foregoing,  each of the Guarantors agrees to the provisions of
any instrument evidencing, securing or otherwise executed in connection with any
Obligation and agrees that the obligations of such Guarantor hereunder shall not
be released or discharged, in whole or in part, or otherwise affected by (a) the
failure of the Agent or any Bank to assert any claim or demand or to enforce any
right or  remedy  against  the  Companies  or any other  entity or other  person
primarily or secondarily liable with respect to any of the Obligations;  (b) any
extensions,   compromise,   refinancing,   consolidation   or  renewals  of  any
Obligation; (c) any change in the time, place or manner of payment of any of the
Obligations or any rescissions, waivers, compromise, refinancing,  consolidation
or other  amendments or  modifications  of any of the terms or provisions of the
Credit  Agreement,  the other Loan Documents or any other agreement  evidencing,
securing or otherwise  executed in connection with any of the  Obligations,  (d)
the addition, substitution or release of any entity or other person primarily or
secondarily liable for any Obligation; (e) the









                                                  -3-


adequacy  of any  rights  which  the  Agent  or an Bank  may  have  against  any
collateral  security  or  other  means  of  obtaining  repayment  of  any of the
Obligations;   (f)  the  impairment  of  any  collateral  securing  any  of  the
Obligations, including without limitation the failure to perfect or preserve any
rights which the Agent or any Bank might have in such collateral security or the
substitution,  exchange,  surrender,  release,  loss or  destruction of any such
collateral security;  or (g) any other act or omission which might in any manner
or to any  extent  vary the risk of such  Guarantor  or  otherwise  operate as a
release or discharge of such Guarantor,  all of which may be done without notice
to  such  Guarantor.  To the  fullest  extent  permitted  by  law,  each  of the
Guarantors  hereby  expressly  waives any and all rights or defenses  arising by
reason of (i) any "one action" or  "anti-deficiency"  law which would  otherwise
prevent the Agent or any Bank from bringing any action,  including any claim for
a deficiency,  or exercising  any other right or remedy  (including any right of
set-off),  against  such  Guarantor  before or after the  Agent's or such Bank's
commencement or completion of any foreclosure  action,  whether  judicially,  by
exercise of power of sale or otherwise, or (ii) any other law which in any other
way would otherwise require any election of remedies by the Agent or any Bank.

         5.  Unenforceability of Obligations Against the Companies.
         If for any reason any  Company  has no legal  existence  or is under no
legal  obligation  to  discharge  any  of  the  Obligations,  or if  any  of the
Obligations  have  become  irrecoverable  from any  Company  by  reason  of such
Company's insolvency,  bankruptcy or reorganization or by other operation of law
or for any other reason,  this  Guaranty  shall  nevertheless  be binding on the
Guarantors  to the same  extent as if the  Guarantors  at all times had been the
principal  obligors on all such  Obligations.  In the event that acceleration of
the time for payment of any of the  Obligations  is stayed upon the  insolvency,
bankruptcy or reorganization of any Company,  or for any other reason,  all such
amounts  otherwise  subject  to  acceleration  under  the  terms  of the  Credit
Agreement, the other Loan Documents or any other agreement evidencing,  securing
or otherwise executed in connection with any Obligation shall be immediately due
and payable by the Guarantors.

         6.  Subrogation; Subordination.

                           6.1.  Waiver of Rights Against the  Companies.  Until
                  the  final  payment  and  performance  in  full  of all of the
                  Obligations,  the  Guarantors  shall not  exercise  and hereby
                  waive any rights against the Companies  arising as a result of
                  payment by the Guarantors  hereunder,  by way of  subrogation,
                  reimbursement,  restitution,  contribution  or otherwise,  and
                  will not prove any claim in competition  with the Agent or any
                  Bank in respect of any payment  hereunder  in any  bankruptcy,
                  insolvency  or  reorganization  case  or  proceedings  of  any
                  nature;  the Guarantors will not claim any setoff,  recoupment
                  or  counterclaim  against  the  Companies  in  respect  of any
                  liability  of  the  Guarantors  to  the  Companies;   and  the
                  Guarantors  waive any benefit of and any right to  participate
                  in any  collateral  security which may be held by the Agent or
                  any Bank.

                           6.2.  Subordination.  The  payment of any amounts due
                  with respect to any  indebtedness  of the  Companies for money
                  borrowed  or  credit  received  now or  hereafter  owed to the
                  Guarantors is hereby subordinated to the prior payment in full
                  of all of the Obligations. Each of the Guarantors









                                                  -4-


                  agrees that,  after the occurrence and during the  continuance
                  of any  default in the  payment or  performance  of any of the
                  Obligations,  such  Guarantor  will  not  demand,  sue  for or
                  otherwise  attempt to  collect  any such  indebtedness  of the
                  Companies to such Guarantor until all of the Obligations shall
                  have  been paid in full.  If,  notwithstanding  the  foregoing
                  sentence, any Guarantor shall collect,  enforce or receive any
                  amounts in respect of such indebtedness  while any Obligations
                  are  still  outstanding,  such  amounts  shall  be  collected,
                  enforced  and  received by such  Guarantor  as trustee for the
                  Banks and the Agent  and be paid  over to the  Agent,  for the
                  benefit  of  the  Banks  and  the  Agent,  on  account  of the
                  Obligations  without  affecting in any manner the liability of
                  the Guarantors under the other provisions of this Guaranty.

                           6.3. Provisions Supplemental.  The provisions of this
                  ss.6 shall be  supplemental  to and not in  derogation  of any
                  rights  and  remedies  of the Banks  and the  Agent  under any
                  separate  subordination  agreement  which the Agent may at any
                  time and from time to time enter into with any  Guarantor  for
                  the benefit of the Banks and the Agent.

         7. Security; Setoff. Each of the Guarantors grants to each of the Agent
and the Banks, as security for the full and punctual  payment and performance of
all of such Guarantor's obligations hereunder, a continuing lien on and security
interest in all securities or other property  belonging to such Guarantor now or
hereafter  held by the  Agent  or such  Bank  and in all  deposits  (general  or
special, time or demand, provisional or final) and other sums credited by or due
from the Agent or such Bank to such  Guarantor or subject to  withdrawal by such
Guarantor.  Regardless of the adequacy of any collateral security or other means
of obtaining payment of any of the Obligations,  each of the Agent and the Banks
is hereby  authorized at any time and from time to time,  without notice to such
Guarantor (any such notice being expressly  waived by such Guarantor) and to the
fullest  extent  permitted by law, to set off and apply such  deposits and other
sums against the obligations of the Guarantors  under this Guaranty,  whether or
not the Agent or such Bank shall have made any demand  under this  Guaranty  and
although such obligations may be contingent or unmatured.

         8. Further Assurances.  Each of the Guarantors agrees that it will from
time to time,  at the  request of the Agent,  do all such things and execute all
such  documents  as the Agent may  consider  necessary or desirable to give full
effect to this Guaranty and to perfect and preserve the rights and powers of the
Banks and the Agent hereunder.  Each of the Guarantors acknowledges and confirms
that such Guarantor  itself has  established its own adequate means of obtaining
from the  Companies  on a  continuing  basis  all  information  desired  by such
Guarantor  concerning  the  financial  condition of the  Companies and that such
Guarantor  will look to the  Companies and not to the Agent or any Bank in order
for such  Guarantor  to keep  adequately  informed of changes in the  Companies'
financial condition.

         9. Termination; Reinstatement. This Guaranty shall remain in full force
and effect until the Agent is given written notice of the Guarantors'  intention
to discontinue this Guaranty, notwithstanding any intermediate or temporary









                                                  -5-


payment  or  settlement  of the  whole or any part of the  Obligations.  No such
notice shall be effective  unless received and acknowledged by an officer of the
Agent at the  address of the Agent for  notices set forth in ss.21 of the Credit
Agreement.  No such  notice  shall  affect  any  rights of the Agent or any Bank
hereunder,  including without  limitation the rights set forth in ss.ss.4 and 6,
with respect to any Obligations incurred or accrued prior to the receipt of such
notice or any  Obligations  incurred  or accrued  pursuant  to any  contract  or
commitment in existence  prior to such receipt.  This Guaranty shall continue to
be effective or be reinstated,  notwithstanding  any such notice, if at any time
any payment made or value  received with respect to any  Obligation is rescinded
or must  otherwise  be  returned  by the Agent or any Bank upon the  insolvency,
bankruptcy or  reorganization of any Company,  or otherwise,  all as though such
payment had not been made or value received.

         10. Successors and Assigns. This Guaranty shall be binding upon each of
the  Guarantors,  its successors and assigns,  and shall inure to the benefit of
the  Agent  and the  Banks and  their  respective  successors,  transferees  and
assigns.  Without limiting the generality of the foregoing  sentence,  each Bank
may assign or otherwise transfer the Credit Agreement,  the other Loan Documents
or any other  agreement  or note held by it  evidencing,  securing or  otherwise
executed in  connection  with the  Obligations,  or sell  participations  in any
interest therein,  to any other entity or other person, and such other entity or
other  person  shall  thereupon  become  vested,  to the extent set forth in the
agreement  evidencing such assignment,  transfer or participation,  with all the
rights in respect  thereof  granted to such Bank herein,  all in accordance with
ss.20 of the  Credit  Agreement.  The  Guarantors  may not  assign  any of their
obligations hereunder.

         11. Amendments and Waivers.  No amendment or waiver of any provision of
this Guaranty nor consent to any departure by any Guarantor  therefrom  shall be
effective  unless the same shall be in writing  and signed by the Agent with the
consent of the Majority  Banks.  No failure on the part of the Agent or any Bank
to exercise, and no delay in exercising,  any right hereunder shall operate as a
waiver thereof;  nor shall any single or partial exercise of any right hereunder
preclude  any other or further  exercise  thereof or the  exercise  of any other
right.

         12. Notices. All notices and other communications  called for hereunder
shall be made in writing and, unless  otherwise  specifically  provided  herein,
shall be deemed to have been duly made or given when delivered by hand or mailed
first class,  postage prepaid, or, in the case of telegraphic or telexed notice,
when  transmitted,  answer  back  received,  addressed  as  follows:  if to  the
Guarantors, at the address set forth beneath its signature hereto, and if to the
Agent,  at the address for notices to the Agent set forth in ss.21 of the Credit
Agreement,  or at such address as either  party may  designate in writing to the
other.

         13. Governing Law;  Consent to Jurisdiction.  THIS GUARANTY IS INTENDED
TO TAKE EFFECT AS A SEALED INSTRUMENT AND SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS. Each of the









                                                  -6-


Guarantors  agrees that any suit for the  enforcement  of this  Guaranty  may be
brought in the courts of the  Commonwealth of Massachusetts or any federal court
sitting therein and consents to the nonexclusive  jurisdiction of such court and
to service of process in any such suit being made upon the Guarantors by mail at
the address  specified  by  reference in ss.12.  Each of the  Guarantors  hereby
waives any objection  that it may now or hereafter have to the venue of any such
suit or any such court or that such suit was brought in an inconvenient court.

         14.  Waiver of Jury Trial.  EACH OF THE  GUARANTORS  HEREBY  WAIVES ITS
RIGHT TO A JURY TRIAL WITH  RESPECT  TO ANY ACTION OR CLAIM  ARISING  OUT OF ANY
DISPUTE IN CONNECTION WITH THIS GUARANTY, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR
THE  PERFORMANCE OF ANY OF SUCH RIGHTS OR  OBLIGATIONS.  Except as prohibited by
law, each of the  Guarantors  hereby waives any right which it may have to claim
or recover in any litigation  referred to in the preceding sentence any special,
exemplary,  punitive or  consequential  damages or any damages other than, or in
addition to, actual  damages.  Each of the Guarantors (i) certifies that neither
the Agent or any Bank nor any representative,  agent or attorney of the Agent or
any Bank has  represented,  expressly or  otherwise,  that the Agent or any Bank
would not, in the event of litigation, seek to enforce the foregoing waivers and
(ii) acknowledges that, in entering into the Credit Agreement and the other Loan
Documents to which the Agent or any Bank is a party, the Agent and the Banks are
relying upon, among other things,  the waivers and  certifications  contained in
this ss.14.

         15.  Miscellaneous.  This Guaranty  constitutes the entire agreement of
the  Guarantors  with  respect to the matters set forth  herein.  The rights and
remedies  herein  provided  are  cumulative  and not  exclusive  of any remedies
provided by law or any other  agreement,  and this Guaranty shall be in addition
to any other guaranty of or collateral security for any of the Obligations.  The
invalidity  or  unenforceability  of any one or more  sections of this  Guaranty
shall not affect the validity or  enforceability  of its  remaining  provisions.
Captions are for the ease of reference  only and shall not affect the meaning of
the relevant provisions. The meanings of all defined terms used in this Guaranty
shall be  equally  applicable  to the  singular  and  plural  forms of the terms
defined.




         IN WITNESS WHEREOF,  each of the Guarantors has caused this Guaranty to
be executed and delivered as of the date first above written.
