         accordance with its terms, subject to applicable bankruptcy,
         insolvency, fraudulent conveyance, reorganization, moratorium and
         similar laws affecting creditors' rights and remedies generally and
         general principles of equity. Neither the Company nor any
         Subsidiary is in violation of any of the provisions of its
         respective certificate or articles of incorporation, by-laws or
         other organizational or charter documents.

                  (d) No Conflicts. The execution, delivery and performance

         any Subsidiary's certificate or articles of incorporation, bylaws
         or other organizational or charter documents, or (ii) subject to
         obtaining the Required Approvals, conflict with, or constitute a
         default (or an event that with notice or lapse of time or both
         would become a default) under, or give to others any rights of
         termination, amendment, acceleration or cancellation (with or
         without notice, lapse of time or both) of, any agreement, credit
         facility, debt or other instrument (evidencing a Company or
         Subsidiary debt or otherwise) or other understanding to which the
         Company or any Subsidiary is a party or by which any property or
         asset of the Company or any Subsidiary is bound or affected, or

         judgment, injunction, decree or other restriction of any court or
         governmental authority to which the Company or a Subsidiary is
         subject (including federal and state securities laws and
         regulations), or by which any property or asset of the Company or a
         Subsidiary is bound or affected; except in the case of each of
         clauses (ii) and (iii), such as would not, individually or in the
         aggregate, reasonably be expected to have or result in a Material
         Adverse Effect.

                      -------------------------------
         nor any Subsidiary is required to obtain any consent, waiver,
         authorization or order of, give any notice to, or make any filing

         Statement, (iii) the notice and/or application(s) to each
         applicable Principal Market for the issuance and sale of the
         Debentures and Warrants and the listing of the Underlying Shares
         for trading thereon in the time and manner required thereby, (iv)
         the filing of Form D with the Commission and applicable Blue Sky
         filings, and (v) the consent of shareholders as discussed in the
         Proxy and as set forth in Section 4.5 hereof (collectively, the
         "Required Approvals").
          ------------------

                  (f) Issuance of the Securities. The Securities are duly
                      --------------------------
         authorized and, when issued and paid for in accordance with the
         applicable Transaction Documents, will be duly and validly issued,
         fully paid and non-assessable, free and clear of all Liens. The
         Company has reserved from its duly authorized capital stock a
         number of shares of Common Stock for issuance of the Underlying
         Shares at least equal to the Required Minimum on the date hereof.
         The Company has not, and to the knowledge of the Company, no
         Affiliate of the Company has sold, offered for sale or solicited
         offers to buy or otherwise negotiate in respect of any security (as
         defined in Section 2 of the Securities Act) that would be
         integrated with the offer or sale of the Securities in a manner
         that would require the registration under the Securities Act of the
         sale of the Securities to the Purchasers, or that would be
         integrated with the offer or sale of the Securities for purposes of
         the rules and regulations of any Principal Market.

                  (g) Capitalization. The number of shares and type of all
                      --------------
         authorized, issued and outstanding capital stock of the Company is
         set forth in the Disclosure Schedules attached hereto. No
         securities of the Company are entitled to preemptive or similar
         rights, and no Person has any right of first refusal, preemptive
         right, right of participation, or any similar right to participate
         in the transactions contemplated by the Transaction Documents.
         Except as a result of the purchase and sale of the Securities,
         there are no outstanding options, warrants, script rights to
         subscribe to, calls or commitments of any character whatsoever
         relating to, or securities, rights or obligations convertible into
         or exchangeable for, or giving any Person any right to subscribe
         for or acquire, any shares of Common Stock, or contracts,
         commitments, understandings or arrangements by which the Company or
         any Subsidiary is or may become bound to issue additional shares of
         Common Stock, or securities or rights convertible or exchangeable
         into shares of Common Stock. The issuance and sale of the
         Securities will not obligate the Company to issue shares of Common
         Stock or other securities to any Person (other than the Purchasers)
         and will not result in a right of any holder of Company securities
         to adjust the exercise, conversion, exchange or reset price under
         such securities.

         the SEC Reports, except where the failure to possess such permits
         would not, individually or in the aggregate, have or reasonably be
         expected to result in a Material Adverse Effect ("Material
                                                           --------
         Permits"), and neither the Company nor any Subsidiary has received
         -------
         any notice of proceedings relating to the revocation or
         modification of any Material Permit.

                  (n) Title to Assets. The Company and the Subsidiaries have
                      ---------------
         good and marketable title in fee simple to all real property owned
         by them that is material to the business of the Company and the
         Subsidiaries and good and marketable title in all personal property
         owned by them that is material to the business of the Company and
         the Subsidiaries, in each case free and clear of all Liens, except
         for Liens as do not materially affect the value of such property
         and do not materially interfere with the use made and proposed to
         be made of such property by the Company and the Subsidiaries. Any
         real property and facilities held under lease by the Company and
         the Subsidiaries are held under valid, subsisting and enforceable
         leases of which the Company and the Subsidiaries are in compliance.

                  (o) Patents and Trademarks. The Company and the
                      ----------------------
         Subsidiaries have, or have rights to use, all patents, patent
         applications, trademarks, trademark applications, service marks,
         trade names, copyrights, licenses and other similar rights
         necessary or material for use in connection with their respective
         businesses as described in the SEC Reports and



                                    -12-

         which the failure to so have would reasonably be expected to have a
         Material Adverse Effect (collectively, the "Intellectual Property
                                                     ---------------------
         Rights"). To the knowledge of the Company, all such Intellectual
         ------
         Property Rights are enforceable and there is no existing
         infringement by another Person of any of the Intellectual Property
         Rights.

                  (p) Insurance. The Company and the Subsidiaries are
                      ---------
         insured by insurers of recognized financial responsibility against
         such losses and risks and in such amounts as are prudent and
         customary in the businesses in which the Company and the
         Subsidiaries are engaged. To the best of Company's knowledge, such
         insurance contracts and policies are accurate and complete. Neither
         the Company nor any Subsidiary has any reason to believe it will
         not be able to renew its existing insurance coverage as and when
         such coverage expires or to obtain similar coverage from similar
         insurers as may be necessary to continue its business without a
         significant increase in cost.

                  (q) Transactions With Affiliates and Employees. Except as
                      ------------------------------------------
         is so minor as to not require disclosure under the Exchange Act and
         applicable regulations, none of the officers or directors of the
         Company and, to the knowledge of the Company, none of the employees
         of the Company is presently a party to any transaction with the
         Company or any Subsidiary (other than for services as employees,
         officers and directors), including any contract, agreement or other
         arrangement providing for the furnishing of services to or by,
         providing for rental of real or personal property to or from, or
         otherwise requiring payments to or from any officer, director or
         such employee or, to the knowledge of the Company, any entity in
         which any officer, director, or any such employee has a substantial
         interest or is an officer, director, trustee or partner.

                  (r) Internal Accounting Controls. The Company and the
                      ----------------------------
         Subsidiaries maintain a system of internal accounting controls
         sufficient to provide reasonable assurance that (i) transactions
         are executed in accordance with management's general or specific
         authorizations, (ii) transactions are recorded as necessary to
         permit preparation of financial statements in conformity with GAAP
         and to maintain asset accountability, (iii) access to assets is
         permitted only in accordance with management's general or specific
         authorization, and (iv) the recorded accountability for assets is
         compared with the existing assets at reasonable intervals and
         appropriate action is taken with respect to any differences. The
         Company has established disclosure controls and procedures (as
         defined in Exchange Act Rules 13a-14 and 15d-14) for the Company
         and designed such disclosures controls and procedures to ensure
         that material information relating to the Company, including its
         subsidiaries, is made known to the certifying officers by others
         within those entities, particularly during the period in which the
         Company's Form 10-K or 10-Q, as the case may be, is being prepared.
         The Company's certifying officers have evaluated the effectiveness
         of the Company's controls and procedures as of a date within 90
         days prior to the filing date of the Form 10-Q for the quarter
         ended March 31, 2003 (such date, the "Evaluation Date"). The
                                               ---------------
         Company presented in the Form 10-Q for the quarter ended March 31,
         2003 the conclusions of the certifying officers about the
         effectiveness of the disclosure controls and procedures based on
         their evaluations as of the Evaluation Date. Since the Evaluation
         Date, there have been no significant changes in the Company's
         internal controls (as such term is defined in Item 307(b) of
         Regulation


                                    -13-

         S-K under the Exchange Act) or, the Company's knowledge, in other
         factors that would reasonably be expected to significantly affect
         the Company's internal controls.

                  (s) Solvency/Indebtedness. Based on the financial
                      ---------------------
         condition of the Company as of each Closing Date: (i) the fair
         saleable value of the Company's assets exceeds the amount that will
         be required to be paid on or in respect of the Company's existing
         debts and other liabilities (including known contingent
         liabilities) as they mature; (ii) the Company's assets do not
         constitute unreasonably small capital to carry on its business for
         the current fiscal year as now conducted and as proposed to be
         conducted including its capital needs taking into account the
         particular capital requirements of the business conducted by the
         Company, and projected capital requirements and capital
         availability thereof; and (iii) the current cash flow of the
         Company, together with the proceeds the Company would receive, were
         it to liquidate all of its assets, after taking into account all
         anticipated uses of the cash, would be sufficient to pay all
         amounts on or in respect of its debt when such amounts are required
         to be paid. The Company does not intend to incur debts beyond its
         ability to pay such debts as they mature (taking into account the
         timing and amounts of cash to be payable on or in respect of its
         debt). The Company has no knowledge of any facts or circumstances
         which lead it to believe that it will file for reorganization or
         liquidation under the bankruptcy or reorganization laws of any
         jurisdiction within one year from the Closing Date. The SEC Reports
         set forth as of the dates thereof all material outstanding secured
         and unsecured Indebtedness of the Company or any Subsidiary, or for
         which the Company or any Subsidiary has commitments. For the
         purposes of this Agreement, "Indebtedness" shall mean (a) any
                                      ------------
         liabilities for borrowed money or amounts owed in excess of $50,000
         (other than trade accounts payable incurred in the ordinary course
         of business), (b) all guaranties, endorsements and other contingent
         obligations, whether or not the same are or should be reflected in
         the Company's balance sheet or the notes thereto, except guaranties
         by endorsement of negotiable instruments for deposit or collection
         in the ordinary course of business, and (c) the present value of
         any lease payments in excess of $50,000 due under leases required
         to be capitalized in accordance with GAAP. Neither the Company nor
         any Subsidiary is in default with respect to any Indebtedness.

                  (t) Certain Fees. No brokerage or finder's fees or
                      ------------
         commissions are or will be payable by the Company to any broker,
         financial advisor or consultant, finder, placement agent,
         investment banker, bank or other Person with respect to the
         transactions contemplated by this Agreement, and the Company has
         not taken any action that would cause any Purchaser to be liable
         for any such fees or commissions. The Company agrees that the
         Purchasers shall have no obligation with respect to any fees or
         with respect to any claims made by or on behalf of any Person for
         fees of the type contemplated by this Section with the transactions
         contemplated by this Agreement.

                  (u) Private Placement. Assuming the accuracy of the
                      -----------------
         representations and warranties of the Purchasers set forth in
         Sections 3.2(b)-(f), the offer, issuance and sale of the Securities
         to the Purchasers as contemplated hereby are exempt from the
         registration requirements of the Securities Act. The issuance and
         sale of the Securities hereunder does not contravene the rules and
         regulations of the Principal Market except that


                                    -14-

<PAGE>
<PAGE>

         Shareholder Approval is required for the Company to issue in excess
         of 7,200,000 shares of Common Stock under the Transaction
         Documents.

                  (v) Listing and Maintenance Requirements. The Company has
                      ------------------------------------
         not, in the 12 months preceding the date hereof, received notice
         from any Principal Market on which the Common Stock is or has been
         listed or quoted to the effect that the Company is not in
         compliance with the listing or maintenance requirements of such
         Principal Market. The Company is, and has no reason to believe it
         will not in the foreseeable future continue to be, in compliance
         with all such listing and maintenance requirements, other than the
         $1 minimum bid price requirement.

                  (w) Registration Rights. Other than to IBM Credit LLC and
                      -------------------
         to shareholders whose shares are included in the registration
         statement of Form S-1 filed by the Company in June 2003, the
         Company has not granted or agreed to grant to any Person any rights
         (including "piggy-back" registration rights) to have any securities
         of the Company registered with the Commission or any other
         governmental authority that have not been satisfied.

                  (x) Application of Takeover Protections. The Company and
                      -----------------------------------
         its Board of Directors have taken all necessary action, if any, in
         order to render inapplicable any control share acquisition,
         business combination, poison pill (including any distribution under
         a rights agreement) or other similar anti-takeover provision under
         the Company's Certificate of Incorporation (or similar charter
         documents) or the laws of its state of incorporation that is or
         could become applicable to the Purchasers as a result of the
         Purchasers and the Company fulfilling their obligations or
         exercising their rights under the Transaction Documents, including
         without limitation as a result of the Company's issuance of the
         Securities and the Purchasers' ownership of the Securities.

                  (y) Seniority. As of the Closing Date, no indebtedness of
                      ---------
         the Company will be senior to the Debentures in right of payment,
         whether with respect to interest or upon liquidation or
         dissolution, or otherwise, other than indebtedness secured by
         purchase money security interests (which is senior only as to
         underlying assets covered thereby) and capital lease obligations
         (which is senior only as to the property covered thereby).

                  (z) Disclosure. The Company confirms that neither it nor
                      ----------
         any other Person acting on its behalf has provided any of the
         Purchasers or their agents or counsel with any information that
         constitutes or might constitute material, nonpublic information.
         The Company understands and confirms that the Purchasers will rely
         on the foregoing representations in effecting transactions in
         securities of the Company. All disclosure provided to the
         Purchasers regarding the Company, its business and the transactions
         contemplated hereby, including the Schedules to this Agreement,
         furnished by or on behalf of the Company with respect to the
         representations and warranties made herein are true and correct
         with respect to such representations and warranties and do not
         contain any untrue statement of a material fact or omit to state
         any material fact necessary in order to make the statements made
         therein, in light of the circumstances under which they were made,
         not misleading. The Company acknowledges and agrees that no
         Purchaser


                                    -15-

<PAGE>
<PAGE>

         makes or has made any representations or warranties with respect to
         the transactions contemplated hereby other than those specifically
         set forth in Section 3.2 hereof.

                  (aa) Form S-3 Eligibility. The Company is not eligible to
                       --------------------
         register the resale of the Underlying Shares for resale by the
         Purchaser on Form S-3 promulgated under the Securities Act.

                  (bb) Tax Status. The Company and each of its Subsidiaries
                       ----------
         has made or filed all federal, state and foreign income and all
         other tax returns, reports and declarations required by any
         jurisdiction to which it is subject (unless and only to the extent
         that the Company and each of its Subsidiaries has set aside on its
         books provisions reasonably adequate for the payment of all unpaid
         and unreported taxes) and has paid all taxes and other governmental
         assessments and charges that are material in amount, shown or
         determined to be due on such returns, reports and declarations,
         except those being contested in good faith and has set aside on its
         books provisions reasonably adequate for the payment of all taxes
         for periods subsequent to the periods to which such returns,
         reports or declarations apply. There are no unpaid taxes in any
         material amount claimed to be due by the taxing authority of any
         jurisdiction, and the officers of the Company know of no basis for
         any such claim. The Company has not executed a waiver with respect
         to the statute of limitations relating to the assessment or
         collection of any foreign, federal, statue or local tax. None of
         the Company's tax returns is presently being audited by any taxing
         authority.

                  (cc) Acknowledgment Regarding Purchasers' Purchase of
                       ------------------------------------------------
         Securities. The Company acknowledges and agrees that the Purchasers
         ----------
         are acting solely in the capacity of arm's length purchasers with
         respect to this Agreement and the transactions contemplated hereby.
         The Company further acknowledges that no Purchaser is acting as a
         financial advisor or fiduciary of the Company (or in any similar
         capacity) with respect to this Agreement and the transactions
         contemplated hereby and any statement made by any Purchaser or any
         of their respective representatives or agents in connection with
         this Agreement and the transactions contemplated hereby is not
         advice or a recommendation and is merely incidental to the
         Purchasers' purchase of the Securities. The Company further
         represents to each Purchaser that the Company's decision to enter
         into this Agreement has been based solely on the independent
         evaluation of the Company and its representatives.

                  (dd) No General Solicitation or Advertising in Regard to
                       ---------------------------------------------------
         this Transaction. Neither the Company nor, to the knowledge of the
         ----------------
         Company, any of its directors or officers (i) has conducted or will
         conduct any general solicitation (as that term is used in Rule
         502(c) of Regulation D) or general advertising with respect to the
         sale of the Debentures or the Warrants, or (ii) made any offers or
         sales of any security or solicited any offers to buy any security
         under any circumstances that would require registration of the
         Debentures, the Underlying Shares or the Warrants under the
         Securities Act or made any "directed selling efforts" as defined in
         Rule 902 of Regulation S.

                  (ee)     No Disagreements with Accountants and Lawyers. There
                           ---------------------------------------------
         are no disagreements of any kind presently existing, or reasonably
         anticipated by the Company to arise, between the accountants and
         lawyers formerly or presently employed by the Company and the
         Company is current with respect to any fees owed to its accountants
         and lawyers.

                  (ff)     DOC Common Stock.
                           ----------------

                           (i)      The DOC Shares have been registered by DOC
                  under the Securities Act. 19,600,000 shares of DOC Common
                  Stock were registered by DOC pursuant to a registration
                  statement filed on Form S-1/A on January 21, 2003 (the
                  "DOC Registration Statement"). The "Plan of Distribution"
                   --------------------------
                  section under each of the DOC Registration Statement
                  permits the pledge and transfer of the DOC Shares as
                  required pursuant to the Transaction Documents.

                           (ii)     The Company is the beneficial owner and the
                  Trustee is the record owner of all of the DOC Shares, free
                  and clear of any Liens, and upon transfer in accordance
                  with the applicable Transaction Documents, the Company and
                  the Trustee will transfer to the Purchasers good and
                  marketable title to such DOC Shares, free and clear of any
                  Liens. Upon any such transfer to the Purchasers of any DOC
                  Shares, and assuming Purchasers are not deemed to be
                  underwriters, and otherwise assuming compliance with the
                  plan of distribution, the DOC Shares shall be unrestricted
                  and freely tradable on the Principal Market without any
                  prospectus delivery or other requirements whatsoever and
                  without the need to make any registration or other filing
                  with the Commission.

                           (iii)    As of the Closing, the Company will have no
                  legal obligation, absolute or contingent, to any other
                  Person to transfer or sell any of the DOC Shares. There is
                  no action, claim, suit, investigation or proceeding
                  pending or, to the knowledge of the Company, threatened by
                  or against or affecting the Company or the DOC Shares
                  before any court or governmental or regulatory authority
                  or body, that could effect the ability of the Company to
                  pledge and transfer to the Purchasers any DOC Shares.
                  There are no writs, decrees, injunctions or orders of any
                  court or governmental or regulatory agency, authority or
                  body outstanding against the Company with respect to the
                  DOC Shares.

         3.2      Representations and Warranties of the Purchasers. Each
                  ------------------------------------------------
Purchaser hereby, for itself and for no other Purchaser, represents and
warrants to the Company as follows:

                  (a)      Organization; Authority. Such Purchaser is an entity
                           -----------------------
         duly organized, validly existing and in good standing under the
         laws of the jurisdiction of its organization with the requisite
         corporate or partnership power and authority to enter into and to
         consummate the transactions contemplated by the Transaction
         Documents and otherwise to carry out its obligations thereunder.
         The purchase by such Purchaser of the Securities hereunder has been
         duly authorized by all necessary action on the part of such
         Purchaser. Each of this Agreement and the Registration Rights
         Agreement have been duly executed


                                    -17-

         by such Purchaser, and when delivered by such Purchaser in
         accordance with the terms hereof, will constitute the valid and
         legally binding obligation of such Purchaser, enforceable against
         it in accordance with its terms.

                  (b)      Investment Intent. Such Purchaser is acquiring the
                           -----------------
         Securities as principal for its own account for investment purposes
         only and not with a view to or for distributing or reselling such
         Securities or any part thereof, without prejudice, however, to such
         Purchaser's right, subject to the provisions of this Agreement, at
         all times to sell or otherwise dispose of all or any part of such
         Securities pursuant to an effective registration statement under
         the Securities Act or under an exemption from such registration and
         in compliance with applicable federal and state securities laws.
         Nothing contained herein shall be deemed a representation or
         warranty by such Purchaser to hold Securities for any period of
         time. Such Purchaser is acquiring the Securities hereunder in the
         ordinary course of its business. Such Purchaser does not have any
         agreement or understanding, directly or indirectly, with any Person
         to distribute any of the Securities.

                  (c)      Purchaser Status. At the time such Purchaser was
                           ----------------
         offered the Securities, it was, and at the date hereof it is, and
         on each date on which it exercises any Warrants or converts any
         Debentures it will be, an "accredited investor" as defined in Rule
         501(a) under the Securities Act. Such Purchaser has not been formed
         solely for the purpose of acquiring the Securities. Such Purchaser
         is not a registered broker-dealer under Section 15 of the Exchange
         Act.

                  (d)      Experience of such Purchaser. Such Purchaser, either
                           ----------------------------
         alone or together with its representatives, has such knowledge,
         sophistication and experience in business and financial matters so
         as to be capable of evaluating the merits and risks of the
         prospective investment in the Securities, and has so evaluated the
         merits and risks of such investment. Such Purchaser is able to bear
         the economic risk of an investment in the Securities and, at the
         present time, is able to afford a complete loss of such investment.

                  (e)      General Solicitation. Such Purchaser is not
                           --------------------
         purchasing the Securities as a result of any advertisement,
         article, notice or other communication regarding the Securities
         published in any newspaper, magazine or similar media or broadcast
         over television or radio or presented at any seminar or any other
         general solicitation or general advertisement.



                                 ARTICLE IV
                       OTHER AGREEMENTS OF THE PARTIES

         4.1      Transfer Restrictions.
                  ---------------------

                  (a) The Securities may only be disposed of in compliance
         with state and federal securities laws. In connection with any
         transfer of Securities other than pursuant to an effective
         registration statement, to the Company or to an Affiliate of a
         Purchaser, the Company may require the transferor thereof to
         provide to the Company an opinion of


                                    -18-

<PAGE>
<PAGE>

         counsel selected by the transferor and reasonably satisfactory to
         the Company, the form and substance of which opinion shall be
         reasonably satisfactory to the Company, to the effect that such
         transfer does not require registration of such transferred
         Securities under the Securities Act. As a condition of transfer,
         any such transferee shall agree in writing to be bound by the terms
         of this Agreement and shall have the rights of a Purchaser under
         this Agreement and the Registration Rights Agreement.

                  (b) The Purchasers agree to the imprinting, so long as is
         required by this Section 4.1(b), of the following legend on any
                          --------------
         certificate evidencing Securities:

         [NEITHER] THESE SECURITIES [NOR THE SECURITIES INTO WHICH THESE
         SECURITIES ARE [EXERCISABLE] [CONVERTIBLE]] HAVE BEEN REGISTERED
         WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES
         COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM
         REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
         "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD
         EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
         SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A
         TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES
         LAWS, ALL AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE
         TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE
         REASONABLY ACCEPTABLE TO THE COMPANY. THESE SECURITIES AND THE
         SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES MAY BE
         PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN
         SECURED BY SUCH SECURITIES.



         The Company acknowledges and agrees that a Purchaser may from time
         to time pledge pursuant to a bona fide margin agreement or grant a
         security interest in some or all of the Securities and, if required
         under the terms of such arrangement, such Purchaser may transfer
         pledged or secured Securities to the pledgees or secured parties.
         If required by the Company's transfer agent in order to effect a
         pledge, the Company shall cause its counsel, at no cost to the
         Purchasers, to issue an opinion of counsel to the Company's
         transfer agent. Further, no notice shall be required of such
         pledge. At the appropriate Purchaser's expense, the Company will
         execute and deliver such reasonable documentation as a pledgee or
         secured party of Securities may reasonably request in connection
         with a pledge or transfer of the Securities, including the
         preparation and filing of any required prospectus supplement under
         Rule 424(b)(3) of the Securities Act or other applicable provision
         of the Securities Act to appropriately amend the list of Selling
         Stockholders thereunder.

                  (c) Certificates evidencing Underlying Shares shall not
         contain any legend (including the legend set forth in Section
         4.1(b) hereof): (i) while a registration statement


                                    -19-

<PAGE>

         (including the Underlying Shares Registration Statement) covering
         the resale of such security is effective under the Securities Act,
         or (ii) following any sale of such Underlying Shares pursuant to
         Rule 144, or (iii) if such Underlying Shares are eligible for sale
         under Rule 144(k), or (iv) if such legend is not required under
         applicable requirements of the Securities Act (including judicial
         interpretations and pronouncements issued by the staff of the
         Commission); provided, however, in connection with the issuance of
                      --------  -------
         the Underlying Shares, each Purchaser, severally and not jointly
         with the other Purchasers, hereby agrees to adhere to and abide by
         all prospectus delivery requirements under the Securities Act and
         Commission Regulations. If all or any portion of a Debenture or
         Warrant is converted or exercised (as applicable) at a time when
         there is an effective registration statement to cover the resale of
         the Underlying Shares, or if such Underlying Shares may be sold
         under Rule 144(k) or if such legend is not otherwise required under
         applicable requirements of the Securities Act (including judicial
         interpretations thereof) then such Underlying Shares shall be
         issued free of all legends. The Company agrees that following the
         Effective Date or at such time as such legend is no longer required
         under this Section 4.1(c), it will, no later than five Trading Days
         following the delivery by a Purchaser to the Company or the
         Company's transfer agent of a certificate representing Underlying
         Securities issued with a restrictive legend, deliver or cause to be
         delivered to such Purchaser a certificate representing such shares
         that is free from all restrictive and other legends. The Company
         may not make any notation on its records or give instructions to
         any transfer agent of the Company that enlarge the restrictions on
         transfer set forth in this Section.

                  (d) In addition to such Purchaser's other available
         remedies, the Company shall pay to a Purchaser, in cash, as
         liquidated damages and not as a penalty, for each $1,000 of
         Underlying Shares (based on the VWAP of the Common Stock on the
         date such Securities are submitted to the Company's transfer agent)
         delivered for removal of the restrictive legend and subject to this
         Section 4.1(c), $10 per Trading Day (increasing to $20 per Trading
         Day 3 Trading Days after such damages have begun to accrue) for
         each Trading Day after such fifth Trading Day until such
         certificate is delivered without a legend.

         4.2      Acknowledgment of Dilution. The Company acknowledges that the
                  --------------------------
issuance of the Securities may result in dilution of the outstanding shares
of Common Stock, which dilution may be substantial under certain market
conditions. The Company further acknowledges that its obligations under the
Transaction Documents, including without limitation its obligation to issue
the Underlying Shares pursuant to the Transaction Documents, are
unconditional and absolute and not subject to any right of set off,
counterclaim, delay or reduction, regardless of the effect of any such
dilution or any claim the Company may have against any Purchaser and
regardless of the dilutive effect that such issuance may have on the
ownership of the other stockholders of the Company. The Company further
acknowledges that the Purchasers may have entered into short sales of the
Common Stock and DOC Common Stock and may continue to enter into short sales
of the Common Stock and DOC Common Stock, in accordance with applicable laws
and regulations, for purposes of hedging. The Company agrees that it will
not raise any claims in connection with any such trading activity referred
to in the prior sentence (nor will the Company support any claims by third
parties in connection with any such trading activity).

         4.3      Furnishing of Information. As long as any Purchaser owns
                  -------------------------
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to the
Exchange Act. Upon the request of any Purchaser, the Company shall deliver
to such Purchaser a written certification of a duly authorized officer as to
whether it has complied with the preceding sentence. As long as any
Purchaser owns Securities, if the Company is not required to file reports
pursuant to such laws, it will prepare and furnish to the Purchasers and
make publicly available in accordance with Rule 144(c) such information as
is required for the Purchasers to sell the Securities under Rule 144. The
Company further covenants that it will take such further action as any
holder of Securities may reasonably request, all to the extent required from
time to time to enable such Person to sell such Securities without
registration under the Securities Act within the limitation of the
exemptions provided by Rule 144.

         4.4      Integration. The Company shall not, and shall use its best
                  -----------
efforts to ensure that no Affiliate of the Company shall, sell, offer for
sale or solicit offers to buy or otherwise negotiate in respect of any
security (as defined in Section 2 of the Securities Act) that would be
integrated with the offer or sale of the Securities in a manner that would
require the registration under the Securities Act of the sale of the
Securities to the Purchasers, or that would be integrated with the offer or
sale of the Securities for purposes of the rules and regulations of any
Principal Market.

         4.5      Reservation and Listing of Securities.
                  -------------------------------------

                  (a) The Company shall maintain a reserve from its duly
         authorized shares of Common Stock for issuance pursuant to the
         Transaction Documents in such amount as may be required to fulfill
         its obligations in full under the Transaction Documents.

                  (b) If, on any date, the number of authorized but unissued
         (and otherwise unreserved) shares of Common Stock is less than 200%
         of (i) the Actual Minimum on such date, minus (ii) the number of
         shares of Common Stock previously issued pursuant to the
         Transaction Documents, then the Board of Directors of the Company
         shall use commercially reasonable efforts to amend the Company's
         certificate or articles of incorporation to increase the number of
         authorized but unissued shares of Common Stock to at least the
         Required Minimum at such time (minus the number of shares of Common
         Stock previously issued pursuant to the Transaction Documents), as
         soon as possible and in any event not later than the 90th day after
         such date; provided that the Company will not be required at any
         time to authorize a number of shares of Common Stock greater than
         the maximum remaining number of shares of Common Stock that could
         possibly be issued after such time pursuant to the Transaction
         Documents.

                  (c) The Company shall: (i) prior to Closing, prepare and
         file with such Principal Market an additional shares listing
         application covering a number of shares of Common Stock at least
         equal to the Required Minimum on the date of such application, (ii)
         take all steps necessary to cause such shares of Common Stock to be
         approved for listing on the Principal Market as soon as possible
         thereafter, (iii) provide to the Purchasers evidence of such
         listing, and (iv) maintain the listing of such Common Stock on such
         Principal Market or another Principal Market. In addition, the
         Company shall


                                    -21-

<PAGE>
<PAGE>

         hold a special meeting of shareholders at the earliest practical
         date, but in no event later than September 15, 2003, for the
         purpose of obtaining a proposal for Shareholder Approval, with the
         recommendation of the Company's Board of Directors that such
         proposal be approved, and the Company shall solicit proxies from
         its shareholders in connection therewith in the same manner as all
         other management proposals in such proxy statement and all
         management-appointed proxyholders shall vote their proxies in favor
         of such proposal. Further, the Company shall use commercially
         reasonable efforts to obtain the written agreement of Richard J.
         Sullivan to vote all Common Stock owned by him as of the record
         date for such meeting in favor of such proposal.

         4.6 DOC Registration Statements. At the Closing, the Company
             ---------------------------
shall deliver to each Purchaser a true, correct and complete copy of each
prospectus pursuant to the DOC Registration Statement. Any transfer of the
DOC Shares by the Company to the Purchasers shall be made pursuant to the
DOC Registration Statement if it shall then be effective, and otherwise by
any other method acceptable to each holder. The Company hereby agrees to use
its reasonable best efforts to cause DOC to, until the date that the Company
shall have transferred the DOC Shares to the Purchasers or none of the
Debentures is outstanding, keep the DOC Registration Statement continuously
effective under the Securities Act and, if and when the Company deems it
necessary, use reasonable best efforts to cause DOC to file one or more
prospectus supplements pursuant to Rule 424(b). The Company shall take all
actions necessary such that the DOC Shares shall remain free of any Lien.
The Company hereby assigns all of its rights and privileges under any
registration rights agreements with DOC to the extent necessary to allow the
Purchasers to enforce such rights with respect to the DOC Shares directly
against the DOC.

         4.7 Transfer of DOC Shares. Upon transfer of any DOC Shares to a
             ----------------------
Purchaser pursuant to the terms of the Transaction Documents, including,
without limitation, pursuant to an exchange under the Debentures, the
Company shall take all actions necessary to transfer to Purchaser, in
accordance with the applicable terms of the Transaction Documents, the DOC
Shares free and clear of all Liens or restrictions such that after such
transfer the DOC Shares will be unrestricted and freely tradable by the
Purchaser. In connection with the foregoing, the Company shall (i) deliver
any prospectus supplement dated after the Closing Date, (ii) cause its
counsel to deliver to the transfer agent of DOC a legal opinion, if required
by the transfer agent to issue any DOC Shares free of a legend, and (iii)
use reasonable best efforts to take any other actions reasonably requested
by any Purchaser in connection with any such transfer. Upon satisfaction in
full of the Debentures and upon exercise in full of the Warrant, Purchasers
shall promptly (but in any event within ten Business Days) send a Final
Payment Notice to the Trustee indicating that the Obligations (as defined in
the Trust) have been satisfied in full.

         4.8 Conversion and Exercise Procedures. The form of exercise
             ----------------------------------
included in the Warrants and the form of Conversion/Exchange Notice included
in the Debentures set forth the totality of the procedures required of the
Purchasers in order to exercise the Warrants or convert/exchange the
Debentures. No additional legal opinion or other information or instructions
shall be required of the Purchasers to exercise their Warrants or
convert/exchange their Debentures. The Company shall honor exercises of the
Warrants and conversions/exchanges of the Debentures and shall deliver
Underlying Shares or DOC Shares in accordance with the terms, conditions and
time periods set forth in the Transaction Documents.


                                    -22-

Further, notwithstanding any breach or alleged breach by any Purchaser of
this Agreement or any other document executed in connection herewith or any
other claim it may have against any Purchaser, the Company agrees that it
shall timely honor conversions, exercises and exchanges by the Purchasers.

the right to assume the defense thereof with counsel of its own choosing.
Any Purchaser Party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Purchaser Party
except to the extent that (i) the employment thereof has been specifically
authorized by the Company in writing, (ii) the Company has failed after a
reasonable period of time to assume such defense and to employ counsel or
(iii) in such action there is, in the reasonable opinion of such separate
counsel, a material conflict on any material issue between the position of
the Company and the position of such Purchaser Party. The Company will not
be liable to any Purchaser Party under this Agreement (i) for any settlement
by an Purchaser Party effected without the Company's prior written consent,
which shall not be unreasonably withheld or delayed; or (ii) to the extent,
but only to the extent that a loss, claim, damage or liability is
attributable to any Purchaser Party's breach of any of the representations,
warranties, covenants or agreements made by the Purchasers in this Agreement
or in the other Transaction Documents.

         4.15 Shareholders Rights Plan. In the event that a shareholders
              ------------------------
rights plan is adopted by the Company, no claim will be made or enforced by
the Company or any other Person that any Purchaser is an "Acquiring Person"
under the plan or in any way could be deemed to trigger the provisions of
such plan by virtue of receiving Securities under the Transaction Documents.

         4.16 Participation in Future Financing. From the date hereof until
              ---------------------------------
such time as a Purchaser no longer holds any Debentures, and except for
Exempt Transactions, the Company shall not effect a financing of its Capital
Shares or Capital Shares Equivalents (a "Subsequent Financing") unless (i)
                                         --------------------
the Company delivers to Purchasers' Representative a written notice at least
5 Trading Days prior to the closing of such Subsequent Financing (the
"Subsequent Financing Notice") of its intention to effect such Subsequent
 ---------------------------
Financing, which Subsequent Financing Notice shall describe in reasonable
detail the proposed terms of such Subsequent Financing, the amount of
proceeds intended to be raised thereunder, the Person with whom such
Subsequent Financing is proposed to be effected, and attached to which shall
be a term sheet or similar document relating thereto and (ii) Purchasers'
Representative shall not have notified the Company by 6:30 p.m. (New York
City time) on the fifth (5th) Trading Day after its receipt of the
Subsequent Financing Notice of its and/or other Purchasers' willingness to
provide (or to cause its designee to provide), subject to completion of
mutually acceptable documentation, all or part of such financing to the
Company on the same terms set forth in the Subsequent Financing Notice. If
one or more Purchasers shall fail to so notify the Company of their
willingness to participate in the Subsequent Financing, the Company may
effect the remaining portion of such Subsequent Financing on the terms and
to the Persons set forth in the Subsequent Financing Notice; provided that
the Company must provide the Purchasers with a second Subsequent Financing
Notice, and the Purchasers will again have the right of first refusal set
forth above in this Section 4.16, if the Subsequent Financing subject to the
initial Subsequent Financing Notice is not consummated for any reason on the
terms set forth in such Subsequent Financing Notice within 60 Trading Days
after the date of the initial Subsequent Financing Notice with the Person
identified in the Subsequent Financing Notice, and if the Company still
desires to effect such financing. In the event the Company receives
responses to Subsequent Financing Notices from Purchasers seeking to
purchase more than the financing sought by the Company in the Subsequent
Financing such Purchasers shall have the right to purchase their Pro Rata
Portion (as defined below) of the Capital Shares or Capital Shares
Equivalents to be issued


                                    -25-

in such Subsequent Financing. "Pro Rata Portion" is the ratio of (x) the
                               ----------------
principal amount of Debentures purchased by a Purchaser and (y) the sum of
the aggregate principal amount of Debentures issued hereunder. If any
Purchaser no longer holds any Debentures, then the Pro Rata Portions shall
be re-allocated among the remaining Purchasers. Notwithstanding anything to
the contrary herein, this Section 4.16 shall not apply to the following (a)
the granting of options to employees, officers and directors of the Company
pursuant to any stock option plan duly adopted by a majority of the
non-employee members of the Board of Directors of the Company or a majority
of the members of a committee of non-employee directors established for such
purpose, or (b) the exercise of the Debenture or any other security issued
by the Company in connection with the offer and sale of this Company's
securities pursuant to this Agreement, or (c) the exercise of or conversion
of any Convertible Securities, options or warrants issued and outstanding on
the Original Issue Date, provided such securities have not been amended
since the date hereof, or (d) acquisitions or strategic investments, the
primary purpose of which is not to raise capital, or (e) any other Exempt
Transaction.

         4.17 Limit on Dividends. So long as any Debenture remains
              ------------------
outstanding, the Company shall not declare or pay any dividend on its Common
Stock in the form of cash or in the form of shares of DOC Common Stock.

                                MISCELLANEOUS

         5.1 Termination. This Agreement may be terminated by any Purchaser,
             -----------
by written notice to the other parties, if the First Closing has not been
consummated on or before July 3, 2003; provided that no such termination
will affect the right of any party to sue for any breach by the other party
(or parties).

         5.2 Fees and Expenses. The Company has agreed to reimburse $50,000
             -----------------
to Midsummer Capital, LLC ("Midsummer") (of which $15,000 has been received)
                            ---------
as reimbursement for its legal, administrative and due diligence fees and
expenses incurred to prepare and negotiate the Transaction Documents. On the
Closing Date, Midsummer Investment Ltd. shall reduce its Subscription Amount
by $35,000 as payment of the remaining portion of the $50,000 referenced
above. Except as expressly set forth in the Transaction Documents to the
contrary, each party shall pay the fees and expenses of its advisers,
counsel, accountants and other experts, if any, and all other expenses
incurred by such party incident to the negotiation, preparation, execution,
delivery and performance of this Agreement. The Company shall pay all
transfer agent fees, stamp taxes and other taxes and duties levied in
connection with the issuance of any Securities. The Purchasers shall pay, on
behalf of the Company, the fees of the placement agents for this transaction
out of closing proceeds, in the aggregate amount of $430,000.

         5.3 Entire Agreement. The Transaction Documents, together with the
             ----------------
exhibits and schedules thereto, contain the entire understanding of the
parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, oral or written, with respect to such
matters, which the parties acknowledge have been merged into such documents,
exhibits and schedules.

             -------------------
waived or amended except in a written instrument signed, in the case of an
amendment, by the Company and each of the Purchasers or, in the case of a
waiver, by the party against whom enforcement of any such waiver is sought.
No waiver of any default with respect to any provision, condition or
requirement of this Agreement shall be deemed to be a continuing waiver in
the future or a waiver of any subsequent default or a waiver of any other
provision, condition or requirement hereof, nor shall any delay or omission
of either party to exercise any right hereunder in any manner impair the
exercise of any such right.

         5.6 Construction. The headings herein are for convenience only, do
             ------------
not constitute a part of this Agreement and shall not be deemed to limit or
affect any of the provisions hereof. The language used in this Agreement
will be deemed to be the language chosen by the parties to express their
mutual intent, and no rules of strict construction will be applied against
any party.

         5.7 Successors and Assigns. This Agreement shall be binding upon
             ----------------------
and inure to the benefit of the parties and their successors and permitted
assigns. The Company may not assign this Agreement or any rights or
obligations hereunder without the prior written consent of the Purchasers.
Notwithstanding anything herein to the contrary, the Company may, without
notice or other action, effect the reincorporation of the Company from
Missouri to Florida, all as set forth in the Proxy. Any Purchaser may assign
its rights under this Agreement and the Registration Rights Agreement to any
Person to whom such Purchaser assigns or transfers any Securities.

         5.8 No Third-Party Beneficiaries. This Agreement is intended for
             ----------------------------
the benefit of the parties hereto and their respective successors and
permitted assigns and is not for the benefit of, nor may any provision
hereof be enforced by, any other Person, except as otherwise set forth in
Sections 4.12.

         5.9 Governing Law; Venue; Waiver of Jury Trial. All questions
             ------------------------------------------
concerning the construction, validity, enforcement and interpretation of
this Agreement shall be governed by and construed and enforced in accordance
with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts
sitting in the City of New York, borough of Manhattan, for the adjudication
of any dispute hereunder or in connection


                                    -27-

<PAGE>
<PAGE>

herewith or with any transaction contemplated hereby or discussed herein
(including with respect to the enforcement of any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any
suit, action or proceeding, any claim that it is not personally subject to
the jurisdiction of any such court, that such suit, action or proceeding is
improper or inconvenient venue for such proceeding. Each party hereby
irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by mailing a copy thereof via
registered or certified mail or overnight delivery (with evidence of
delivery) to such party at the address in effect for notices to it under
this Agreement and agrees that such service shall constitute good and
sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any manner
permitted by law. The parties hereby waive all rights to a trial by jury. If
either party shall commence an action or proceeding to enforce any
provisions of this Agreement, then the prevailing party in such action or
proceeding shall be reimbursed by the other party for its attorneys fees and
other costs and expenses incurred with the investigation, preparation and
prosecution of such action or proceeding.

         5.10 Survival. The representations, warranties, agreements and
              --------
covenants contained herein shall survive the Closings and the delivery,
exercise and/or conversion of the Securities, as applicable, for the
applicable statute of limitations.

         5.11 Execution. This Agreement may be executed in two or more
              ---------
counterparts, all of which when taken together shall be considered one and
the same agreement and shall become effective when counterparts have been
signed by each party and delivered to the other party, it being understood
that both parties need not sign the same counterpart. In the event that any
signature is delivered by facsimile transmission, such signature shall
create a valid and binding obligation of the party executing (or on whose
behalf such signature is executed) with the same force and effect as if such
facsimile signature page were an original thereof.

         5.12 Severability. If any provision of this Agreement is held to be
              ------------
invalid or unenforceable in any respect, the validity and enforceability of
the remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a
valid and enforceable provision that is a reasonable substitute therefor,
and upon so agreeing, shall incorporate such substitute provision in this
Agreement.

         5.13 Rescission and Withdrawal Right. Notwithstanding anything to
              -------------------------------
the contrary contained in (and without limiting any similar provisions of)
the Transaction Documents, whenever any Purchaser exercises a right,
election, demand or option under a Transaction Document and the Company does
not timely perform its related obligations within the periods therein
provided, then such Purchaser may rescind or withdraw, in its sole
discretion from time to time upon written notice to the Company, any
relevant notice, demand or election in whole or in part without prejudice to
its future actions and rights, provided, however, in the case of a
rescission of a conversion of a Debenture or exercise of a Warrant, the
Purchaser shall be required to return any shares of Common Stock subject to
any such conversion or exercise notice.

         5.14 Replacement of Securities. If any certificate or instrument
              -------------------------
evidencing any Securities is mutilated, lost, stolen or destroyed, the
Company shall issue or cause to be issued in exchange and substitution for
and upon cancellation thereof, or in lieu of and substitution therefor, a
new certificate or instrument, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and customary
and reasonable indemnity, if requested. The applicants for a new certificate
or instrument under such circumstances shall also pay any reasonable
third-party costs associated with the issuance of such replacement
Securities.

         5.15 Remedies. In addition to being entitled to exercise all rights
              --------
provided herein or granted by law, including recovery of damages, each of
the Purchasers and the Company will be entitled to specific performance
under the Transaction Documents. The parties agree that monetary damages may
not be adequate compensation for any loss incurred by reason of any breach
of obligations described in the foregoing sentence and hereby agrees to
waive in any action for specific performance of any such obligation the
defense that a remedy at law would be adequate. Without limiting the
generality of the foregoing, the Company expressly agrees that its breach of
the next-to-last last sentence of Section 4.7 would cause each Purchaser
irreparable harm, and consents to the granting of injunctive relief by any
court having jurisdiction to preclude any such issuance of securities.

         5.16 Payment Set Aside. To the extent that the Company makes a
              -----------------
payment or payments to any Purchaser pursuant to any Transaction Document or
a Purchaser enforces or exercises its rights thereunder, and such payment or
payments or the proceeds of such enforcement or exercise or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set
aside, recovered from, disgorged by or are required to be refunded, repaid
or otherwise restored to the Company, a trustee, receiver or any other
person under any law (including, without limitation, any bankruptcy law,
state or federal law, common law or equitable cause of action), then to the
extent of any such restoration the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and
effect as if such payment had not been made or such enforcement or setoff
had not occurred.

         5.17 Usury. To the extent it may lawfully do so, the Company hereby
              -----
agrees not to insist upon or plead or in any manner whatsoever claim, and
will resist any and all efforts to be compelled to take the benefit or
advantage of, usury laws wherever enacted, now or at any time hereafter in
force, in connection with any claim, action or proceeding that may be
brought by any Purchaser in order to enforce any right or remedy under any
Transaction Document. Notwithstanding any provision to the contrary
contained in any Transaction Document, it is expressly agreed and provided
that the total liability of the Company under the Transaction Documents for
payments in the nature of interest shall not exceed the maximum lawful rate
authorized under applicable law (the "Maximum Rate"), and, without limiting
                                      ------------
the foregoing, in no event shall any rate of interest or default interest,
or both of them, when aggregated with any other sums in the nature of
interest that the Company may be obligated to pay under the Transaction
Documents exceed such Maximum Rate. It is agreed that if the maximum
contract rate of interest allowed by law and applicable to the Transaction
Documents is increased or decreased by statute or any official governmental
action subsequent to the date hereof, the new maximum contract rate of
interest allowed by law will be the Maximum Rate applicable to the


                                    -29-

<PAGE>
<PAGE>

Transaction Documents from the effective date forward, unless such
application is precluded by applicable law. If under any circumstances
whatsoever, interest in excess of the Maximum Rate is paid by the Company to
any Purchaser with respect to indebtedness evidenced by the Transaction
Documents, such excess shall be applied by such Purchaser to the unpaid
principal balance of any such indebtedness or be refunded to the Company,
the manner of handling such excess to be at such Purchaser's election.

         5.18 Independent Nature of Purchasers' Obligations and Rights. The
              --------------------------------------------------------
obligations of each Purchaser under any Transaction Document are several and
not joint with the obligations of any other Purchaser, and no Purchaser
shall be responsible in any way for the performance of the obligations of
any other Purchaser under any Transaction Document. Nothing contained herein
or in any Transaction Document, and no action taken by any Purchaser
pursuant thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert or
as a group with respect to such obligations or the transactions contemplated
by the Transaction Document. Except as expressly set forth herein with
respect to the Purchasers' Representative, whose duties as to the Company's
and DOC's equity are purely ministerial, and whose discretionary duties
relate solely to the Purchasers status as secured creditors of the Company,
each Purchaser shall be entitled to independently protect and enforce its
rights, including without limitation the rights arising out of this
Agreement or out of the other Transaction Documents, and it shall not be
necessary for any other Purchaser to be joined as an additional party in any
proceeding for such purpose. Each Purchaser has been represented by its own
separate legal counsel in their review and negotiation of the Transaction
Documents. For reasons of administrative convenience only, Purchasers and
their respective counsel have chosen to communicate with the Company through
FW. FW does not represent all of the Purchasers but only Midsummer. The
Company has elected to provide all Purchasers with the same terms and
Transaction Documents for the convenience of the Company and not because it
was required or requested to do so by the Purchasers.

         5.19 Liquidated Damages. The Company's obligations to pay any
              ------------------
liquidated damages or other amounts owing under the Transaction Documents is
a continuing obligation of the Company and shall not terminate until all
unpaid liquidated damages and other amounts have been paid notwithstanding
the fact that the instrument or security pursuant to which such liquidated
damages or other amounts are due and payable shall have been canceled.

                           ***********************
