health, disability and major medical insurance plans, and in such other
employee benefit plans and programs, for the benefit of the employees of the
Parent and its affiliates, as may be maintained from time to time during the
Term, in each case to the extent and in the manner available to other
officers of the Parent and subject to the terms and provisions of such plans
or programs.  In addition, Executive will be afforded the same indemnity
provisions regarding directors and officers liability that the parent
provides to its other senior executive officers and directors and Executive
will be covered by any directors and officers liability policy generally in
force for the Parent's senior executive officers and directors.

          (c)  EQUITY ARRANGEMENTS.

               (i)  Executive shall participate during each calendar year
during the Term commencing with fiscal year 1999, in the Parent's stock and
performance incentive plans (or such plans of the Parent's affiliates
maintained for the benefit of other officers of Parent) on the same basis as
is made available to other executives of the Parent; it being understood that
Executive's entitlement to performance based compensation in respect of
fiscal years 1996, 1997 and 1998 shall be as set forth in Section
4.1(c)(iii)(2) and (3) below.

               (ii)  Executive and the Parent hereby acknowledge and agree
that the Deferred Stock award with respect to 15,868 shares of DC's common
stock granted to Executive under the DC 1994 Stock Incentive Plan (the "DC
Incentive Plan") in connection with DC's initial public offering which will
not have vested prior to the Effective Date shall be deemed fully vested
immediately prior to the Effective Date, such shares to be converted into
shares of common stock of Parent pursuant to the Merger Agreement.

               (iii)  Executive and Parent hereby acknowledge and agree that
with respect to the Long-Term Incentive Deferred Stock award relating to
533,000 shares of DC's common stock previously granted to Executive under the
DC Incentive Plan, of which 35,534 shares have previously vested and been
issued:

                      (1)  an aggregate of 97,616 shares of DC common stock,
(relating to 1994 and 1995 fiscal year performance) shall be deemed fully
vested immediately prior to the Effective Date, such shares to be converted
into shares of common stock of Parent pursuant to the Merger Agreement;
PROVIDED that if Executive determines that such vesting would result in the
imposition of any excise tax on Executive under Section 4999 of the Internal
Revenue Code of 1986, as amended, at Executive's request, Parent will provide
that such shares will be deemed to vest over a period of time, as agreed by
Parent and Executive, in consideration of Executive's future performance of
services so as to avoid the imposition of any such excise tax by the
Executive;

                      (2)  106,600 shares of DC common stock (relating to
1996 fiscal year performance), subject to conversion into shares of common
stock of Parent pursuant to the Merger Agreement, will no longer be subject
to vesting on the basis of performance but will vest, subject to Executive's
continued
<PAGE>
                                                                              5

employment with the Parent, in equal 1/3 portions on each of the first,
second and third anniversaries of the Effective Date; and

                      (3)  the remaining 293,150 shares of DC common stock,
133,250 relating to 1997 fiscal year performance and 159,900 shares relating
to 1998 fiscal year performance, shall be converted into shares of common
stock of Parent pursuant to the Merger Agreement and shall be earned upon the
Parent's achievement of Funds From Operations growth targets for fiscal years
1997 and 1998, respectively, established by the committee then administering
the DC Incentive Plan which, as provided in Section 5.12 of the Merger
Agreement, shall not exceed $2.58 per share for fiscal year 1997 and $2.79
per share for fiscal year 1998, (the "FFO Targets"), calculated in a manner
consistent with that proposed by the National Association of Real Estate
Investment Trusts.  Once earned, such shares shall vest, subject to
Executive's continued employment with the Parent, in equal 1/3 portions on
each of the first three April 1sts that occur after the last day of the
fiscal year to which such earned shares relate.

               (d)  BONUS OPPORTUNITY.  Executive shall participate during
the Term in the Parent's (or its affiliates') annual cash bonus plan for
senior executives of the Parent as in effect from time to time, with a
maximum annual bonus for each year during the Term equal to at least 75% of
Executive's base salary.

               (e)  VACATION.  Executive shall be entitled to a reasonable
paid vacation period (but not necessarily consecutive vacation weeks) during
the Term.

reimburse, Executive for reasonable business-related expenses incurred by him
in connection with the performance of his duties hereunder during the Term,
subject, however, to the Parent's and the Company's policies relating to
business-related expenses as in effect from time to time during the Term.

     5.1  EXCLUSIVITY.  Executive agrees to perform his duties,
responsibilities and obligations hereunder efficiently and to the best of his
ability.  Executive agrees that he will devote his entire working time, care
and attention and best efforts to such duties, responsibilities and
obligations throughout the Term.  Executive also agrees that he will not
engage in any other business activities, whether charitable or pursued for
gain, profit, other pecuniary advantage or otherwise, that are competitive
with the activities of the Parent or its affiliates or that would adversely
<PAGE>
                                                                              6

effect Executive's ability to perform his duties hereunder.  Executive agrees
that all of his activities as an employee and/or trustee or director of the
Parent or its affiliates shall be in conformity with all present and future
policies, rules and regulations and directions of the Parent and its
affiliates not inconsistent with this Agreement.

     5.2  OTHER BUSINESS VENTURES.  Executive agrees that for so long as he
is employed by the Parent, and for a period of one year thereafter, he will
not, directly or indirectly, become an employee, shareholder, owner, officer,
agent, director of, or otherwise associate with, any firm, person, business
enterprise or other entity which is engaged in or competitive with, any
business engaged in by the Parent or its affiliates.  Notwithstanding the
foregoing, Executive may own, directly or indirectly, up to 5% of the
outstanding capital stock of any business having a class of capital stock
which is traded on any national stock exchange or in the over-the-counter
market.

     5.3  CONFIDENTIALITY; NON-SOLICITATION.  (a)  Executive agrees that he
will not, at any time during or after the Term, make use of or divulge to any
other person, firm, business enterprise or other entity, any trade or
business secret, process, method or means, or any other confidential
information concerning the business or policies of the Parent or its
affiliates including, without limitation, any information, data, or other
confidential information relating to customers, development programs, costs,
marketing, trading, investment, sales activities, promotion, credit and
financial data, manufacturing processes, financing methods, plans or the
business and affairs of the Parent or its affiliates generally; PROVIDED that
the foregoing shall not apply to information which is not unique to the
Parent or its affiliates or which is generally known to the industry or the
public other than as a result of the Executive's breach of this covenant.
Executive agrees not to remove from the premises of the Parent or its
affiliates, except as an employee of the Parent or its affiliates in pursuit
of the business of the Parent or its affiliates or except as specifically
permitted in writing by the Parent, any document or other object containing
or reflecting any such confidential information.  Executive recognizes that
all such documents and objects, whether developed by him or by someone else,
will be the sole exclusive property of the Parent and its affiliates.  Upon
termination of his employment hereunder, Executive shall forthwith deliver to
the Parent all such confidential information, including without limitation
all lists of customers, correspondence, accounts, records and any other
documents or property made or held by him or under his control in relation to
the business or affairs of the Parent or its affiliates, and no copy of any
such confidential information shall be retained by him.

         (b)  Executive agrees that for so long as he is employed by the
Parent and for a period of one year thereafter, Executive shall not, directly
or indirectly, whether as an employee, consultant, independent contractor,
partner, joint venturer or otherwise, (A) solicit or induce, or in any manner
attempt to solicit or induce, any person employed by, or as agent of, the
Parent or its affiliates to terminate such person's contract of employment or
agency, as the case may be, with the Parent or its affiliates, (B) employ or
offer employment to any person who was employed by the Parent or its
affiliates in other than a purely administrative capacity unless such person
shall have ceased to be employed by the Parent or its affiliates for
<PAGE>
                                                                              7

a period of at least 12 months, or (C) divert, or attempt to divert, any
person, concern, or entity from doing business with the Parent or its
affiliates, nor will he attempt to induce any such person, concern or entity
to cease being a customer or supplier of the Parent or its affiliates.

          (c)  Executive agrees that, at any time and from time to time
during and after the Term, he will execute any and all documents which the
Parent may deem reasonably necessary or appropriate to effectuate the
provisions of this Section 5.3.

     5.4  SPECIFIC PERFORMANCE.  Executive acknowledges and agrees that the
Parent's remedies at law for a breach or threatened breach of any of the
provisions of this Article V would be inadequate and, in recognition of this
fact, Executive agrees that, in the event of such a breach or threatened
breach, in addition to any remedies at law, the Parent, without posting any
bond, shall be entitled to seek equitable relief in the form of specific
performance, temporary restraining order, temporary or permanent injunction
or any other equitable remedy which may then be available.


                                   ARTICLE VI

                                  TERMINATION

     6.1  TERMINATION BY THE PARENT.  The Parent shall have the right to
terminate this Agreement and Executive's employment hereunder at any time
during the Term with or without "Cause."  For purposes of this Agreement,
"Cause" shall mean (i) a substantial and continued failure by Executive to
perform his duties hereunder or (ii) Executive's conviction of a felony;
PROVIDED that no termination for Cause as a result of any of the events
described in clause (i) shall be deemed effective unless and until the Parent
shall have provided Executive with written notice specifying in detail the
action(s) or event(s) allegedly constituting grounds for the Cause
termination and the Executive shall have failed to cure such action(s) or
event(s) within 10 days of receipt of such notice.  Any such termination
without cause or due to Executive's conviction of a felony shall be effective
upon the giving of notice thereof to Executive in accordance with Section 7.3
hereof, and any termination which is based on any of the action(s) or
events(s) described in clause (i) shall be effective as of the 10th day
following Executive's receipt of such notice if Executive shall have failed
to cure the applicable action(s) or event(s).

     6.2  DEATH.  In the event Executive dies during the Term, this Agreement
shall automatically terminate, such termination to be effective on the date
of Executive's death.

     6.3  DISABILITY.  In the event that Executive shall suffer a disability
during the Term which shall have prevented him from performing satisfactorily
his obligations hereunder for a period of at least 90 consecutive days, the
Parent shall have the right to terminate this Agreement and Executive's
employment hereunder, such termination to be effective upon the giving of
notice thereof to Executive in accordance with Section 7.3 hereof.
<PAGE>
                                                                              8

     6.4  TERMINATION BY EXECUTIVE FOR GOOD REASON.  This Agreement and
Executive's employment hereunder may be terminated during the Term by
Executive with or without Good Reason, by giving 30 days advance written
notice to the Parent in accordance with Section 7.3.  For purposes of this
Agreement, the following circumstances shall constitute "Good Reason":

          (a)  the assignment to Executive of any duties inconsistent in any
material respect with Executive's position (including status, offices, titles
and reporting requirements), or with his authority, duties or
responsibilities as contemplated by Sections 2.1 and 2.2 of this Agreement,
or any other action by the Parent or its successor which results in a
material diminution or material adverse change in Executive's titles,
position, status, authority, duties or responsibilities (including, without
limitation, removal of Executive from, or failure to secure the Executive's
election or appointment to, the Board or the Executive Committee of the Board
without the Executive's written consent during any period when the number of
directors constituting the entire Board equals or exceeds 13, other than as a
result of Executive's death or disability);

          (b)  any material breach by the Parent or its successor of the
provisions of this Agreement;

          (c)  any failure by the Parent to comply with and satisfy Section
7.2(b) of this Agreement; or

          (d)  a relocation of Executive's principal base of operation to any
location other than Youngstown, Ohio during the term of Executive's
employment hereunder; PROVIDED that the requirement that Executive devote at
least a majority of his business time to duties performed at the Parent's
corporate offices in Indianapolis, Indiana at any time after the first
anniversary of the Effective Date shall not constitute a relocation of
Executive's principal base of operation for purposes of this Agreement;

          PROVIDED that no termination by Executive for Good Reason shall be
deemed effective unless and until the Executive shall have provided the
Parent with written notice specifying in detail the action(s) or event(s)
allegedly constituting grounds for the Good Reason termination and the Parent
shall have failed to cure such action(s) or event(s) within 10 days of
receipt of such notice.

     6.5  EFFECT OF TERMINATION.

          (a)  In the event of termination of this Agreement during the Term
by either party for any reason, or by reason of the Executive's death, the
Company shall pay to Executive (or his beneficiary in the event of his death)
any base salary earned but not paid to Executive prior to the effective date
of such termination, together with any other earned and currently payable,
but then unpaid, compensation.

         (b)  In the event of the termination of this Agreement during the
Term (i) by the Parent without Cause (other than due to Executive's death or
<PAGE>

                                                                              9

disability), (ii) by Executive for Good Reason or (iii) by reason of the
Parent's election not to renew the Term through the third anniversary of the
Effective Date as provided in Section 3.1 hereof (each, a "Wrongful
Termination"), the Company shall pay to Executive, in addition to the amounts
described in Section 6.5(a) hereof, an amount equal to one-year's then
current base salary and bonus, in twelve equal monthly installments following
the date of such termination (the "Cash Severance").  For this purpose,
Executive's then current bonus shall be Executive's maximum target bonus for
the Parent's fiscal year within which such termination occurs.  In addition,
the deferred stock award shares described in Section 4.1(c)(iii)(2) shall (to
the extent not then vested) be deemed fully vested as of the date of such
termination of employment and (x) the deferred stock award shares described
in Section 4.1(c)(iii)(3) which have been earned as of the date of such
termination, if any, shall (to the extent not then vested) be deemed fully
vested as of the date of such termination of employment and (y) the deferred
stock award shares described in Section 4.1(c)(iii)(3) which are "deemed"
earned as described in the next succeeding sentence shall be deemed fully
vested as of the last day of the fiscal year in which such Wrongful
Termination occurs.  For purposes of this Section 6.5(b), deferred stock
awards described in Section 4.1(c)(iii)(3) shall be "deemed" earned with
respect to a fiscal year if the Wrongful Termination occurs after August 31
of such fiscal year and the FFO Targets for such fiscal year are subsequently
determined to have been met.

          (c)  Unless otherwise agreed among the parties in writing, in the
event of the termination of this Agreement due to the expiration of the Term
(i) on the third anniversary of the Effective Date or (ii) as a result of
Executive's notice to the Parent electing not to renew the Term pursuant to
Section 3.1, Executive shall be entitled to no further benefits hereunder,
other than those described in Section 6.5(a), and any continuation of
Executive's employment with the Parent beyond the expiration of the Term shall
be deemed an employment at will and shall not be deemed to extend any of the
provisions of this Agreement, and Executive's employment may thereafter be
terminated at will by Executive or the Parent; PROVIDED that (x) if Executive
shall remain employed with the Parent through the third anniversary of the
Effective Date and Executive shall resign his employment upon the expiration
of the Term due to the Parent's failure to offer Executive continued
employment with the Parent for at least an additional one year period (the
"Extension Period") on terms substantially equivalent in all material
respects to those set forth in this Agreement (other than principal base of
operation for performance), including, without limitation, each of the
termination provisions set forth in this Section 6.5 (including this
Section 6.5(c) which shall apply at the expiration of the Extension Period
should Executive remain employed by the Parent through the conclusion of such
Extension Period) (such terms of continued employment being hereinafter
referred to a "Substantially Equivalent Terms"), then such resignation shall
be treated under this Agreement as a Wrongful Termination and the provisions
of Section 6.5(b) shall apply and (y) if the Executive shall remain employed
with the Parent through the third anniversary of the Effective Date and the
Executive shall resign his employment upon the expiration of the Term due to
the Parent's offer to Executive of continued employment on Substantially
Equivalent Terms but which would require Executive's relocation to an area
outside of Youngstown, Ohio, then Executive shall be entitled to elect, by
delivery of written notice to the Parent coincident with; or within 15 days
<PAGE>

                                                                             10

following, such resignation of employment, EITHER (A) to cause the Parent to
provide that the vesting of the deferred stock award shares described in
Section 4.1(c)(iii)(2) and Section 4.1(c)(iii)(3) shall be accelerated in the
same manner and to the same extent described in Section 6.5(b) or (B) to
require that the Company pay Executive the Cash Severance.

          (d)  In the event of Executive's termination of employment by
Parent due to Executive's disability or as a result of Executive's death, in
addition to Executive's entitlement to the amounts described in Section
6.5(a), the vesting of the deferred stock award shares described in Section
4.1(c)(iii)(2) and Section 4.1(c)(iii)(3) shall be accelerated in the same
manner and to the same extent described in Section 6.5(b).

          (e)  Except as expressly provided in this Article VI, the Parent
shall have no further obligations to Executive under this Agreement following
Executive's termination of employment with the Parent.  Any other benefits

indirect, by operation of law, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of the
