                           It is anticipated that the Recapitalization will be

                           "EXCHANGE OFFER AND CONSENT SOLICITATION"), or (b) if
                           the Exchange Offer and Consent Solicitation is not
                           consummated, a prearranged or prepackaged plan of
                           reorganization pursuant to the U.S. Bankruptcy Code
                           on substantially the same terms as the terms
                           described in the Term Sheet (the "PREARRANGED PLAN").


                           ACL Holdings, the Company, DHC and the members of ACL
                           Holdings have signed a recapitalization agreement
                           (the "RECAPITALIZATION AGREEMENT"), which is on

                           in the Term Sheet, pursuant to which DHC and/or one
                           or more of its subsidiaries will acquire 100% of the

                           set forth in the Recapitalization Agreement.

RIGHTS OFFERING

                           In connection with the Recapitalization, DHC shall
                           conduct a rights offering ("RIGHTS OFFERING") of
                           rights to purchase ("RIGHTS") an aggregate of
                           approximately $43.6 million of newly issued shares of
                           Common Stock, par value $.01 per share ("COMMON
                           STOCK"), the net proceeds of which shall be used to
                           satisfy DHC's cash contribution obligations in the
                           Recapitalization as described in the Term Sheet and,
                           to the extent of any excess proceeds, general
                           corporate purposes.



                           The purchase price for the Common Stock in the Rights
                           Offering will be $5.00 per share ("SUBSCRIPTION
                           PRICE"), and the total number of Common Stock shares
                           to be offered will be approximately 8.7 million.

                           The Rights shall be offered to each stockholder
                           (including, without limitation, to Standby Purchaser
                           with respect to the Warrant Shares (as defined
                           below)) on a pro rata basis ("BASIC SUBSCRIPTION
                           RIGHT") and shall be nontransferable. Stockholders
                           who fully exercise their basic subscription right
                           shall also be entitled to subscribe for any Common
                           Stock shares offered in the Rights Offering and not
                           purchased by other stockholders, subject to proration
                           (in proportion to the number of Common Stock shares a
                           stockholder has subscribed for pursuant to the basic
                           subscription right) if the oversubscribed shares
                           exceed the number of Common Stock shares available
                           ("OVERSUBSCRIPTION RIGHT"). Exercise of the basic
                           subscription right and the oversubscription right
                           shall be subject, in each instance, to the
                           restrictions contained in Article Fifth of DHC's
                           Certificate of Incorporation and such other transfer
                           restrictions and/or stock certificate escrow
                           protection mechanisms as may be imposed by DHC in
                           accordance with past practice to insure compliance
                           with Article Fifth.

STANDBY PURCHASER
WARRANT EXERCISE           Provided that the condition precedents specified
                           under the heading "Conditions to Standby Purchaser's
                           Obligations" below have been satisfied, or waived by
                           Standby Purchaser in its sole discretion in writing,
                           then, simultaneously with the closing of the Rights
                           Offering, Standby Purchaser shall exercise in full
                           its warrant dated August 12, 1999, for 1,898,000
                           Common Stock shares, at a current exercise price of
                           $4.74391 per share ("WARRANT"), resulting in the
                           issuance of 1,900,437 Common Stock shares ("WARRANT
                           SHARES") as a result of such exercise.
                           Notwithstanding the foregoing, for purposes of the
                           Rights Offering, all Warrant shares shall be treated
                           as if exercised such that the Warrant Shares shall
                           have basic subscription rights and oversubscription
                           rights as if the Warrant Shares were in fact issued
                           and outstanding as of the commencement of the Rights
                           Offering. If necessary, DHC shall amend its
                           registration statement to allow the Warrant to
                           participate in the Rights Offering on an "as
                           exercised" basis.

STANDBY COMMITMENTS        Standby Purchaser shall be obligated to purchase up
                           to 4.0 million Common Stock shares offered in the
                           Rights Offering, (i) which are not otherwise
                           subscribed for pursuant to basic subscription rights
                           and oversubscription rights and (ii) the purchase of
                           which by Standby Purchaser would not require Standby
                           Purchaser to make an HSR filing or insurance
                           regulatory filing(s) or DHC to obtain approval of its
                           stockholders under SEC or AMEX rules or other
                           applicable requirements (either requirement, an
                           "APPROVAL

                           REQUIREMENT LIMITATION") ("STANDBY SHARES"). In the
                           event Standby Purchaser would be otherwise obligated
                           to purchase hereunder Common Stock shares but is

                           file the necessary filings under the HSR Act or
                           applicable insurance regulatory requirements (and DHC
                           shall cooperate with Standby Purchaser in preparing
                           its filing and shall make DHC's required filings) or
                           DHC shall take all actions and prepare and make such
                           filings necessary to obtain approval of it's
                           stockholders, as the case may be, 2) loan to DHC an
                           amount equal to the number of shares it did not
                           purchase due to the Approval Requirement Limitation
                           multiplied by $5.00, at an interest rate of 12% per
                           annum payable in cash with a maturity of the earlier

                           pursuant to the following clause 3) and on other
                           standard and customary terms (the "BRIDGE LOAN"), and
                           3) upon clearance under the HSR Act, insurance
                           commissioners or receipt of approval of DHC's
                           stockholders, as the case may be, purchase the Common
                           Stock shares it did not purchase due to the Approval
                           Requirement Limitation provision at $5.00 per share
                           (and DHC shall use such proceeds to repay the Bridge
                           Loan).

                           out of or are based upon (i) any inaccuracy in,
                           breach of or failure to comply with, any
                           representation, warranty, or covenant made by DHC in

                           supplement thereto, or the omission or alleged
                           omission to state therein a material fact required to
                           be stated therein or necessary to make the statements
                           therein not misleading, except insofar as any such
                           untrue statement or omission or alleged untrue
                           statement or omission was made in such, preliminary
                           prospectus, the Registration Statement or the

                           Indemnitee may become subject to the extent resulting
                           from, due to or based upon Standby Purchaser having
                           entered into this Summary of Terms or agreeing

                           with this Summary of Terms; provided, however, if
                           such Losses are solely the result of the amount of
                           the Standby Fee, DHC shall only be obligated for
                           Losses in excess of the amount of the Standby Fee
                           actually paid to Standby Purchaser.

                           Standby Purchaser agrees to indemnify and hold DHC,
                           its affiliates, any of its or their affiliates, and

                           sources (each, a "DHC INDEMNITEE") harmless from and
                           against any and all Losses to which any DHC
                           Indemnitee may become subject insofar as such Losses
                           arise out of or are based upon any inaccuracy in,
                           breach of or failure to comply with, any
                           representation, warranty, or covenant made by DHC in
                           this Summary of Terms.

                           prior written consent of the other party hereto.

                           This Summary of Terms constitutes the entire
                           agreement between Standby Purchaser and DHC with

                           enforceability of any such provision in every other
                           respect and of the remaining provisions contained
                           herein shall not be in any way affected or impaired
                           thereby or under the laws of any other jurisdiction.
