$167,000 in debt, a three-year 9% promissory note for $1,095,500 and an
eighteen-month 9% promissory note for $350,000. In addition, the Company has
agreed to make cash earnout payments as set forth in the DMO agreement based on

     1.03 Assumption of Liabilities. Except for the liabilities and obligations

          1.04-1 $6,087,500 payable by cashiers check or wire transfer on the
Closing Date.

          1.04-2 $1,262,500 less the principal amount of any debt or capital

(to the extent such liabilities are not paid or discharged prior to the Closing
Date);

               1.04-3(b) all liabilities of DMO of a type identified on Schedule

               1.04-3(c) all obligations of DMO under any of the Leases or

               1.04-3(d) all obligations of DMO under any lease, contract,

entered into by DMO between the date of this Agreement and the Closing Date that
GD Sub, in its sole discretion, elects on the Closing Date to assume.

          1.04-4 Additional payments to be made by check to DMO or its assigns
(the "Earnout Payments") based on the Earnout EBITDA (as defined below) for the
36-month period (the "Earnout Period") beginning on the first day of the first
calendar month following the Closing Date. For any 12-month period, the "Earnout
EBITDA" shall mean the amount by which the EBITDA (as defined below) for such
period exceeds $2,000,000. The first Earnout Payment shall equal 1.1 multiplied
by the Earnout EBITDA, if any, for the first 12 months of the Earnout Period up
to $2,000,000 of Earnout EBITDA and .66 multiplied by any Earnout EBITDA for
such period in excess of $2,000,000 of Earnout EBITDA. The second Earnout
Payment shall equal 1.1 multiplied by the Earnout EBITDA, if any, for the second
12 months of the Earnout Period up to $2,000,000 of Earnout EBITDA and .66
multiplied by any Earnout EBITDA for such period in excess of $2,000,000 of
Earnout EBITDA. The third Earnout Payment shall equal 1.1 multiplied by the
Earnout EBITDA, if any, for the third 12 months of the Earnout Period up to
$2,000,000 of Earnout EBITDA and .66 multiplied by any Earnout EBITDA for such
period in excess of $2,000,000 of


                                        4
<PAGE>
Earnout EBITDA. The "EBITDA" shall mean the combined net income of (a) the
Professional Corporation, (b) CDC and (c) GD Sub from the provision of services
to the Professional Corporation, before any reduction for interest, income
taxes, depreciation, amortization or impairment of intangible assets, and
excluding any allocation of GDSC or GD Sub corporate or regional overhead
expense or management fees, but including a Charge For Excess Capital
Expenditures (as defined below), as reflected on a combined income statement
prepared in conformity with generally accepted accounting principles applied in
a manner consistent with the application of such principles to the preparation
of GDSC's audited financial statements. The "Charge For Excess Capital
Expenditures" shall be equal to 20% of the total accumulated capital
expenditures after the date of this Agreement incurred by (a) the Professional
Corporation, (b) CDC and (c) GD Sub in connection with services provided to the
Professional Corporation, which in any year exceeds 2.5% of the combined net
revenue of the Professional Corporation and CDC for such year. The calculation
and payment of each Earnout Payment shall be completed within 120 days of the
completion of the applicable 12-month portion of the Earnout Period.

          In the event DMO disputes the calculation of EBITDA for any given
12-month period, DMO shall notify GD Sub of each disputed item and the amount
within forty-five (45) days of delivery to DMO of the EBITDA calculation and
payment. If DMO and GD Sub cannot resolve the dispute within ten (10) days
thereafter, the amount in dispute ("Disputed Amount") shall be resolved by a
national accounting firm mutually selected by DMO and GD Sub ("Independent
Accounting Firm"). The determination of the Independent Accounting Firm shall be
final and binding on the parties. Any expenses relating to the Independent
Accounting Firm shall be allocated between DMO and GD Sub so that DMO's share of
such expenses shall bear the same proportion to the total expenses as the total
of the Disputed Amount unsuccessfully contested by DMO (as determined by the
Independent Accounting Firm) bears to the total of the Disputed Amount so
submitted to the Independent Accounting Firm.

          During the Earnout Period, the parties understand and agree that the
businesses of CDC and the Professional Corporation will be operated in the same
general manner as those businesses were operated prior to the Closing Date.

     1.05 Purchase Price Adjustment. The Purchase Price may be subject to
adjustment after Closing as set forth in this Section 1.05.

          1.05-1 As soon as reasonably possible after Closing, the amount of the
"Net Current Assets" (as defined in Section 1.05-3) shall be determined as
provided in Section 1.05-4. If the amount of Net Current Assets is $30,000 more
or less than $158,000, the Purchase Price shall be adjusted by the full amount
of the difference (the "Purchase Price Adjustment"). If the difference between
Net Current Assets and $158,000 does not exceed $30,000, there shall be no
Purchase Price Adjustment.

          1.05-2 If the Net Current Assets are greater than $188,000, the
Purchase Price Adjustment shall be paid to DMO by check within 10 days after DMO
delivers the certificate described in Section 1.05-4. If the Net Current Assets
are less than $128,000, the Purchase Price Adjustment shall be paid by DMO to GD
Sub by check within 10 days after DMO delivers the certificate described in
Section 1.05-4.


                                        5
<PAGE>
          1.05-3 "Net Current Assets" means the sum of (a) accounts receivable
of the Business, net of contractual allowances and bad debt reserve, as of the
Closing Date and (b) any prepaid expenses properly recordable on a balance sheet
for the Business as of the Closing Date reduced by the sum of (x) the accounts
payable of the Business at the Closing Date and (y) the accrued liabilities of
the Business at the Closing Date, specifically including an accrual of payroll
and payroll-related charges (other than accrued vacation, sick pay and paid time
off) up to and including the Closing Date, but only to the extent such payables
and liabilities are assumed by GD Sub, all as determined consistently with the
accounting conventions applied in determining the amounts set forth in
paragraphs 1.05-1 and 1.05-2 above.

          1.05-4 At or promptly after the Closing Date, DMO shall execute and
deliver to GD Sub a certificate detailing the calculation of Net Current Assets
and including as schedules thereto lists of all receivables, prepaid expenses,
payables and accrued liabilities as of the Closing Date included in the
calculation. In this certificate DMO shall certify the accuracy and completeness
of the schedules to the certificate and the accuracy of the calculation of Net
Current Assets.

     1.06 Employees. Effective as of the close of business on the Closing Date,
DMO shall terminate all employees of its Business. GD Sub or the Professional
Corporation shall extend immediately to all of DMO's employees an offer of
employment, on substantially the same terms and conditions as were in effect
prior to the Closing, for hire in accordance with GD Sub's standard hiring
practices. DMO will notify such employees prior to the Closing that as of such
date they shall cease to be employees and will be offered employment by GD Sub
or the Professional Corporation; the form and content of notice shall be subject
to GD Sub's prior written approval.

     1.07 Instruments of Conveyance and Transfer. The sale of the Assets, and
the conveyance, assignment, transfer and delivery of all of the Assets other
than the patient charts and the Professional Contracts, shall be effected by
DMO's execution and delivery to GD Sub, on the Closing Date, of a bill of sale
in substantially the form of the Assignment and Bill of Sale attached hereto as
Exhibit C. The conveyance, assignment, transfer and delivery of DMO's patient
charts and the Professional Contracts shall be effected by DMO's execution and
delivery to the Professional Corporation, on the Closing Date, of an assignment
in substantially the form of the Assignment attached hereto as Exhibit D.

     1.08 Further Assurances. DMO and Shareholders agree that, at any time and
from time to time on and after the Closing Date, they will, upon the request of
GD Sub and without further consideration, take all steps reasonably necessary to
place GD Sub (or the Professional Corporation, as the case may be) in possession
and operating control of the Assets, and will do, execute, acknowledge and
deliver, or will cause to be done, executed, acknowledged and delivered, all
further acts, deeds, assignments, conveyances, transfers, powers of attorney or
assurances as reasonably required to sell, assign, convey, transfer, grant,
assure and confirm to GD Sub (or the Professional Corporation, as the case may
be), or to aid and assist in the collection of or reducing to possession by GD
Sub (or the Professional Corporation, as the case may be) of, all of the Assets,
or to vest (or the Professional Corporation, as the case may be) in GD Sub good,
valid and marketable title to the Assets.


                                        6
<PAGE>
     1.09 Closing. The consummation of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Stoel Rives LLP,
900 SW Fifth Avenue, Suite 2300, Portland, Oregon, on October 30, 1998 effective
as of the close of business on that date, or at another date, time and place
agreed upon in writing by the parties (the "Closing Date").

     1.10 Allocation of Purchase Price. The Purchase Price shall be allocated
among the Assets in accordance with Schedule 1.10, which shall be completed as
soon as reasonably possible after the Closing, and GD Sub and DMO shall be bound
by that allocation in reporting the transactions contemplated by this Agreement
to any governmental authority (including without limitation the Internal Revenue
Service). Because the parties could not fix the value of the intangibles
associated with the Business being purchased by GD Sub, the parties have agreed
to establish the earn-out provided in Section 1.04-4 as additional consideration
for those assets.

     1.11 Covenant Not to Compete.

          1.11-1 DMO and Shareholders shall not, for a period extending from the
Closing Date to the date three years after the end of the Earnout Period, except
on behalf of GD Sub, CDC or Professional Corporation, directly or indirectly do
any of the following:

               (a) Practice dentistry in the State of Oregon, other than as a
solo practitioner located outside a ten-mile radius of any location where GDSC,
GD Sub or any of their respective subsidiaries owns, manages, develops, or
operates any dental practice;

               (b) In any way solicit or initiate contact with, for purposes of
providing dental services, anyone who is a patient or customer, or the family
member of a patient or customer, of the Business;

               (c) Solicit, employ or contract with any employee of the
Business;

               (d) In any way solicit or initiate contact with, or enter into a
contract or subcontract with or relating to, the Oregon Health Plan;

               (e) Be a partner, shareholder, employee, agent or consultant or
otherwise be associated with any partnership, corporation, proprietorship or
other entity that does any of the things mentioned in this subsections (a), (b),
(c) or (d); provided, however, that the ownership by DMO or any Shareholder of
less than five percent of the equity securities of any publicly-traded
corporation shall not constitute a violation of this subsection (e).

          1.11-2 DMO and Shareholders agree that it would be difficult to
measure damage to GDSC and GD Sub from any breach of the promises set forth in
Section 1.11 of this Agreement, and that money damages would therefore be an
inadequate remedy for any such breach. Accordingly, DMO and Shareholders agree
that if DMO and Shareholders breach any provision of Section 1.11, GDSC and GD
Sub shall be entitled, in addition to all other remedies they may have, to
injunctions or other appropriate orders to restrain any such breach by DMO and

business in compliance with its articles of incorporation and bylaws and all
applicable laws and regulations. DMO is not in violation of any applicable laws
or regulations, other than violations which singly or in the aggregate do not,

not subject to any outstanding order, writ, injunction or decree, and DMO has
not been charged with, or threatened with a charge of, a violation of any
provision of federal, state or local law or regulation.

     3.06 Employment Matters.

          3.06-1 Labor Matters

               (a) DMO is not a party or otherwise subject to any collective
bargaining or other agreement governing the wages, hours or terms of employment
of its employees. DMO is and has been in compliance with all applicable laws
regarding employment and employment practices, terms and conditions of
employment, wages and hours and is not and has not been engaged in any unfair
labor practice.

               (b) There is no (1) unfair labor practice complaint against DMO
pending before the National Labor Relations Board or any other governmental
authority, (2) labor strike, slowdown or work stoppage actually occurring or, to
the best of the knowledge of DMO, threatened


                                       10
<PAGE>
against him, (3) representation petition respecting DMO's employees pending
before the National Labor Relations Board, or (4) grievance or any arbitration
proceeding pending arising out of or under collective bargaining agreements
applicable to DMO.

               (c) DMO has not experienced any primary work stoppage or other
organized work stoppage involving its employees in the past two years.

          3.06-2 Employee Benefits. Schedule 3.06-2 lists all pension,
retirement, profit sharing, deferred compensation, bonus, commission, incentive,
life insurance, health and disability insurance, hospitalization and all other
employee benefit plans or arrangements (including, without limitation, any
contracts or agreements with trustees, insurance companies or others relating to
any such employee benefit plans or arrangements) established or maintained by
DMO, and complete and accurate copies of all those plans or arrangements have
been provided to GD Sub. The employee pension benefit plans (within the meaning
of Section 3(2) of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA") established and maintained by DMO that are subject to ERISA
are listed separately as ERISA Plans on Schedule 3.06-2 (the "ERISA Plans"). The
ERISA Plans comply with the applicable requirements of ERISA. Each of the ERISA
Plans is qualified under Section 401(a) of the Internal Revenue Code of 1986, as
amended (the "Code") and the related trust is tax-exempt under Section 501(a) of
the Code. No "accumulated funding deficiency" as defined in Section 302(a)(2) of
ERISA or Section 412(a) of the Code exists, or has existed, with respect to any
of the ERISA Plans. The present value of all accrued benefits under each of the
ERISA Plans does not exceed the value of such plan's assets, less all
liabilities other than those attributable to accrued benefits. DMO has no
"potential withdrawal liability," as defined in Section 4201 of ERISA. None of
the ERISA Plans, its related trusts or any trustee, investment manager or
administrator thereof has engaged in a nonexempt "prohibited transaction," as
such term is defined in Section 406 of ERISA and Section 4975 of the Code. There
are not and have not been any excess deferrals or excess contributions under any
ERISA Plan. Each ERISA Plan is and has been operated and administered in
conformance with the requirements of all applicable laws and regulations,
whether or not the ERISA Plan documents have been amended to reflect such
requirements. Except for DMO's 1998 Performance Plan, DMO has no obligation of
any kind (whether under the terms of the ERISA Plans or under any understanding
with employees) to make payments under, or to pay contributions to or in respect
of, any plan or arrangement listed on Schedule 3.06-2, or any other plan,
agreement or other arrangement for deferred compensation of employees, whether
or not tax qualified, including, without limitation, a single employer tax
qualified plan, a tax qualified plan of a controlled group of corporations, a
multi-employer pension plan, a nonqualified deferred compensation plan, an
individual employment or compensation agreement or a commitment to provide
medical benefits to retirees.

          3.06-3 Employment Agreements. Except as listed on Schedule 3.06-3,
each of DMO's employees is an "at-will" employee and there are no written
employment, commission or compensation agreements of any kind between DMO and
any of DMO's employees. Schedule 3.06- 3 lists all of DMO's employment or
supervisory manuals, employment or supervisory policies, and written information
generally provided to employees (such as applications or notices), and true and
complete copies of those manuals, policies and written information have been
provided to GD Sub. DMO does not have any agreements or understandings with
DMO's employees except as reflected in the items listed in Schedules 3.06-2 and
3.06-3.

Contracts or Leases may be totally or partially terminated or suspended by the
other parties.

agreement that DMO can reasonably foresee will result in any material loss to

assets, materially interfere with any present or intended use of any such
property or assets or materially adversely affect the marketability of such
properties or assets.

is bound or to which any of its properties or assets is subject limits the
freedom of DMO to compete in any line of business or with any person.

     3.22 Permits and Licenses. DMO and Shareholders hold and at all times have

in compliance with all the terms of each Permit, and there are no claims of
violation by DMO or Shareholders of any Permit.

     3.23 Certain Payments. Neither DMO nor any other person or entity has,

     9.04 Indemnification Procedure.

          9.04-1 Third Party Claims.

               (a) Each indemnified party shall, with reasonable promptness
after obtaining knowledge thereof, provide any indemnifying party against whom a
claim for indemnification is to be made under this Article 9 with written notice
of all third party actions, suits, proceedings, claims, demands or assessments
that may be subject to the indemnification provisions of this Article 9
(collectively, "Third Party Claims"), including, in reasonable detail, the basis
for the claim, the nature of Damages and a good faith estimate of the amount of
Damages.

               (b) Each indemnifying party shall have 15 days after its receipt
of the claim notice to notify the indemnified party in writing whether the
indemnifying party agrees that the claim is subject to this Article 9 and, if
so, whether the indemnifying party elects, jointly with any other indemnifying
party notified under Section 9.04-1(a), to undertake, conduct and control,
through counsel of its or their choosing (subject to the consent of the
indemnified party, such consent not to be withheld unreasonably) and at its or
their sole risk and expense, the good faith settlement or defense of the Third
Party Claim.

               (c) If within 15 days after its receipt of the claim notice an
indemnifying party notifies the indemnified party that it elects to undertake
the good faith settlement or defense of the Third Party Claim, the indemnified
party shall cooperate reasonably with the indemnifying party in connection
therewith including, without limitation, by making available to the indemnifying
party all relevant information material to the defense of the Third Party Claim.
The indemnified party shall be entitled to participate in the settlement or
defense of the Third Party Claim through counsel chosen by the indemnified
party, at its expense, and to approve any proposed settlement that would impose
any obligation or duty on the indemnified party, which approval may, in the sole


                                       26
<PAGE>
discretion of the indemnified party, be withheld. So long as an indemnifying
party is contesting the Third Party Claim in good faith and with reasonable
diligence, the indemnified party shall not pay or settle the Third Party Claim.
Notwithstanding the foregoing, the indemnified party shall have the right to pay
or settle any Third Party Claim at any time, provided that in such event it
waives any right to indemnification therefor by the indemnifying party.

               (d) If an indemnifying party does not provide notice that it
elects to undertake the good faith settlement or defense of the Third Party
Claim, or if an indemnifying party fails to contest the Third Party Claim or
undertake or approve settlement, in good faith and with reasonable diligence,
the indemnified party shall thereafter have the right to contest, settle or
compromise the Third Party Claim in good faith at its exclusive discretion, at
the risk and expense of the indemnifying party, and the indemnifying party will
thereby waive any claim, defense or argument that the indemnified party's
settlement or defense of such Third Party Claim is in any respect inadequate or
unreasonable.

               (e) A party's failure to give timely notice will not constitute a
defense, in part or in whole, to any claim for indemnification by such party,
except if, and only to the extent that, such failure results in any material
prejudice to the indemnifying party.

          9.04-2 Non-Third Party Claims.

               (a) Each indemnified party shall, with reasonable promptness,
deliver to any indemnifying party against whom a claim for indemnification is to
be made under this Article 9 written notice of all claims for indemnification
under this Article 9, other than Third Party Claims, including, in reasonable
detail, the basis for the claim, the nature of Damages and a good faith estimate
of the amount of Damages.

               (b) Each indemnifying party shall have 30 days after its receipt
of the claim notice to notify the indemnified party in writing whether the
indemnifying party accepts liability for all or any part of the Damages
described in the claim notice. If the indemnifying party does not so notify the
indemnified party, the indemnifying party shall be deemed to accept liability
for all the Damages described in the claim notice.

               (c) A party's failure to give timely notice will not constitute a
defense, in part or in whole, to any claim for indemnification by such party,
except if, and only to the extent that, such failure results in any material
prejudice to the indemnifying party.

     9.05 Right of Offset. At the election of GD Sub, any liability of DMO or
Shareholders under Section 9.02 of this Agreement or under Section 9.02 of the
CDC Agreement which has been established by agreement, litigation or in
accordance with the procedure set forth in Section 9.04 of this Agreement or the
CDC Agreement may be satisfied by offsetting such liability against the
outstanding principal and interest balance payable under the Promissory Notes or
against any Earnout Payment then due or that subsequently becomes due; provided,
however that if DMO or Shareholders give notice to GD Sub within 30 days after
DMO or Shareholders receive a notice of claim under Section 9.04-1(a) or
9.04-2(a) of this Agreement or the CDC Agreement that DMO or Shareholders


                                       27
<PAGE>
contest its or their liability for such claim, GD Sub may not exercise its right
of offset until the procedure described in Section 9.06 has been completed.

     9.06 Arbitration of Contested Offset.

          9.06-1 Arbitration of Disputes Over Offset. If DMO or Shareholders
give notice contesting its or their liability for all or any part of a claim in
accordance with Section 9.05, then such dispute shall be settled by mandatory
binding arbitration in Portland, Oregon in accordance with the provisions of
this Section 9.06 and the Commercial Arbitration Rules of the American
Arbitration Association then in effect (the "AAA Rules"), unless GD Sub and DMO
or Shareholders settle such dispute in a written settlement agreement executed
by GD Sub and DMO or Shareholders. The provisions of this Section 9.06 shall
prevail and govern in the event of any conflict between such provisions and the
AAA Rules.

          9.06-2 Arbitrator. Unless otherwise mutually agreed by GD Sub and DMO,
the arbitration will be heard and decided by a single arbitrator who shall be
selected as provided in Section 9.06-3.

          9.06-3 Selection of Arbitrator. GD Sub and DMO will have the authority
to select the arbitrator from a list of arbitrators who are attorneys-at-law who
practice business law and have significant experience with respect to the
representation of health care companies; provided that the arbitrator cannot
have represented GD Sub, DMO or any Shareholder in any previous matter. If GD
Sub and DMO cannot agree on the selection of the arbitrator from the above list
of arbitrators, then the arbitrator shall be chosen by the American Arbitration
Association.

          9.06-4 Time for Arbitration Decision: Effect. The arbitrator shall
decide each dispute to be arbitrated pursuant hereto within ninety (90) days
after the selection of arbitrator. The arbitrator's decision shall relate solely
to whether GD Sub is entitled to indemnification in connection with the claim
(or a portion thereof) pursuant to the applicable terms of this Agreement or the
CDC Agreement. The final decision of the arbitrator shall specify the amount (if
any) that GD Sub is entitled to offset in connection with the claim, shall be
furnished to GD Sub, DMO, and Shareholders in writing, shall constitute a
conclusive determination of all issues in question, binding upon GD Sub, DMO,
and Shareholders and shall not be contested by any of them. Upon the conclusion
of any arbitration proceedings hereunder, the arbitrator will render findings of
fact and conclusions of law and a written opinion setting forth the basis and
reasons for any decision reached and will deliver such documents to GD Sub, DMO
and Shareholders, along with a signed copy of the award. The arbitrator chosen
in accordance with these provisions will not have the power to alter, amend or
otherwise affect the terms of this Section 9.06 or the provisions of this
Agreement or the CDC Agreement. Judgment upon the award rendered by the
arbitrator may be entered in any court having competent jurisdiction over the
subject matter thereof.

          9.06-5 Right to Counsel. GD Sub (on behalf of itself and any
Indemnified Person(s)) and DMO or Shareholders shall each have the right to
employ its or their own legal counsel to represent such person in any disputes
arising under this Agreement.


                                       28

          9.06-6 Compensation of Arbitrator. The arbitrator will be compensated
for his or her services at a rate to be determined by the parties or by the
American Arbitration Association, but based upon reasonable hourly or daily
consulting rates for the arbitrator in the event the parties are not able to
agree upon his or her rate of compensation. GD Sub, on the one hand, and DMO or
Shareholders, on the other hand, will each pay 50% of the initial compensation
to be paid to the arbitrator in any such arbitration and 50% of the costs of
transcripts and other normal and regular expenses of the arbitration proceedings
(collectively, the "Arbitration Expenses").

     9.07 Limitations.

          9.07-1 Any amounts payable under Section 9.02 or 9.03 or this Section
shall be treated by GD Sub, DMO and Shareholders as an adjustment to the
Purchase Price, and shall be calculated after giving effect to (i) any proceeds
received from insurance policies covering the Damages that are the subject of
the indemnification, and (ii) the actual recognized tax benefit to the
indemnified party resulting from the Damages that are the subject of the
indemnification; provided that to the extent that any tax benefit is recognized
in a tax year later than the year in which the indemnification payment is made,
no adjustment for tax benefit shall be made in determining the amount of the
indemnification payment and the indemnified party shall make a payment to the
indemnifying party in an amount of such recognized tax benefit in the year in
which it is realized. For purposes of this Section 9.07-1, an actual recognized
tax benefit is an actual reduction in taxes payable or a refund of taxes
previously paid.

          9.07-2 The indemnification obligations set forth in Sections 9.02 and
9.03 of this Agreement and Sections 9.02 and 9.03 of the CDC Agreement with
respect to breaches of representations or warranties shall not apply unless the
total amount of Damages with respect to such breaches incurred either by GD
Sub's Indemnified Persons or by DMO and/or Shareholders (as the case may be)
exceeds $200,000 in the aggregate, as a result of all matters giving rise to
rights to indemnification for such breaches under those Sections. In the event
that the amount of such Damages exceeds that threshold, GD Sub's Indemnified
Persons or DMO and Shareholders (as the case may be) shall be entitled to
indemnification for the full amount of all such Damages to the extent that the
full amount of all such Damages exceeds $100,000, subject to Section 9.07-3.

          9.07-3 The right of GD Sub's Indemnified Persons to seek
indemnification from DMO and/or Shareholders under this Agreement or the CDC
Agreement shall terminate the sooner of (a) 39 months after the Closing Date or
(b) with respect to claims under Section 9.04-2 of this Agreement and Section
9.04-2 of the CDC Agreement, at such time as the total Damages paid by DMO
and/or Shareholders in respect of such claims (whether or not paid by offset of
amounts owed to DMO or Shareholders) reaches a total of $5,000,000.00 or (c)
with respect to all claims, at such time as the total Damages paid by DMO and/or
Shareholders in respect of such claims (whether or not paid by offset of amounts
owed to DMO or Shareholders) reaches a total equal to the full amount of the
Purchase Price under this Agreement and the CDC Agreement.

     9.08 Exclusive Rights. An indemnified party's rights to indemnification
under this Article 9 shall be the exclusive remedy in the event of any breach of
any representation or warranty under this Agreement.

amended or waived only by an instrument in writing signed by the party against
which enforcement of such amendment or waiver is sought. Any waiver of any term
or condition of this Agreement or any breach hereof shall not operate as a

provision hereof.

           900 Washington Street, Suite 1100
           Vancouver, WA  98660
           Telecopy No.:  (360) 750-8667                                  "GDSC"


AND:       CAPITOL DENTAL CARE, INC.
             an Oregon corporation
           540 Liberty St. SE
           Salem, OR 97301
           Telecopy No.: (503) 581-0043                                    "CDC"


AND:       James M. Harlow, DDS
           Jeffrey O. Jackson                                     "Shareholders"


     Shareholders are the owners of all of the issued and outstanding capital
stock of CDC. Shareholders desires to sell, and GDSC desires to purchase, all of
the shares of capital stock of CDC outstanding on the Closing Date (the "CDC
Shares") on the terms and conditions set forth in this Agreement, thereby
causing CDC to become a wholly-owned subsidiary of GDSC. As part of a single
integrated plan, CDC desires to redeem a portion of the CDC Shares from the
Shareholders on the Closing Date (the "Redemption") pursuant to a Redemption
Agreement in the form attached as Exhibit A (the "Redemption Agreement"). The
parties desire that the Shareholders sell to GDSC all CDC Shares that are not
redeemed (the "Purchased CDC Shares") on the terms and conditions set forth in
this Agreement. Shareholders are also the owners of all of the issued and
outstanding capital stock of Dental Maintenance of Oregon, P.C., an Oregon
corporation ("DMO"). Shareholders and GDSC are signing an agreement for the
purchase and sale of substantially all of the assets of DMO (the "DMO
Agreement") at the same time that they are signing this Agreement.

     In consideration of the mutual promises and covenants contained in this
Agreement, the parties agree as follows:

<PAGE>
                                    ARTICLE I

                         Purchase and Sale of CDC Shares

     1.01 Purchase and Sale. Subject to all the terms and conditions of this
Agreement and for the consideration herein stated, on the "Closing Date," as
that term is defined in Section 1.06, Shareholders agree to sell, convey,
assign, transfer and deliver the Purchased CDC Shares to GDSC, and GDSC agrees
to purchase and accept the Purchased CDC Shares from Shareholders. On the
Closing Date, all CDC Shares shall either be purchased by GDSC under this
Agreement or redeemed by CDC under the Redemption Agreement so that after the
Closing CDC shall be a wholly-owned subsidiary of GDSC.

     1.02 Purchase Price. The total purchase price for the Purchased CDC Shares
(the "Purchase Price") shall be $737,500 less the principal amount of any debt
or capital lease obligations of CDC as of the Closing Date, payable to the
Shareholders pro rata according to their ownership of CDC Shares (50.1% to Dr.
Harlow and 49.9% to Mr. Jackson) by delivery to each Shareholder of a promissory
note (the "Promissory Note") in the form attached as Exhibit B.

     1.03 Purchase Price Adjustment. The Purchase Price may be subject to
adjustment after Closing as set forth in this Section 1.03.

          1.03-1 As soon as reasonably possible after Closing, the amount of the
"Net Worth" (as defined in Section 1.03-3) shall be determined as provided in
Section 1.03-4. If the amount of Net Worth is more or less than $275,000, the
Purchase Price shall be adjusted by the full amount of the difference (the
"Purchase Price Adjustment").

          1.03-2 If the Net Worth is greater than $275,000, the Purchase Price
Adjustment shall be paid to Shareholders by check within 10 days after GDSC
delivers the certificate described in Section 1.03-4. If the Net Worth is less
than $275,000, the Purchase Price Adjustment shall be paid by Shareholders to
GDSC by check within 10 days after GDSC delivers the certificate described in
Section 1.03-4.

          1.03-3 "Net Worth" means the net worth of CDC as of the Closing Date,
after giving effect to the Redemption, determined on a basis consistent with how
net worth is calculated for purposes of Section 7 of Exhibit A of CDC's contract
with the Oregon Health Plan.

          1.03-4 At or promptly after the Closing Date, GDSC shall execute and
deliver to Shareholders a certificate detailing the calculation of Net Worth. In
this certificate GDSC shall certify the accuracy of the calculation of Net
Worth.

     1.04 Instruments of Transfer. On the Closing Date, Shareholders shall
deliver to GDSC certificates for all of the Purchased CDC Shares, duly endorsed
for transfer. Shareholders shall also deliver to GDSC for cancellation
certificates for all of the redeemed CDC Shares.


                                        2
<PAGE>
     1.05 Further Assurances. Shareholders agree that, at any time and from time
to time on and after the Closing Date, they will, upon the request of GDSC and
without further consideration, take all steps reasonably necessary to place GDSC
in possession and operating control of the business of CDC and the assets and
properties of CDC.

     1.06 Closing. The consummation of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Stoel Rives LLP,
900 SW Fifth Avenue, Suite 2300, Portland, Oregon, on October 30, 1998 effective
as of the close of business on that date, or at another date, time and place
agreed upon in writing by the parties (the "Closing Date").


                                   ARTICLE II

                     Representations and Warranties of GDSC

     GDSC represents and warrants to CDC and Shareholders as follows:

     2.01 Authorization. GDSC is a corporation, duly organized, validly existing
and in good standing under the laws of the State of Washington and has all
requisite corporate power and authority to own and operate its properties and to
carry on its business as now conducted. GDSC has taken all corporate action
necessary to authorize its execution, delivery and performance of this
Agreement. GDSC has full corporate power and authority to enter into this
Agreement and carry out the terms hereof. This Agreement has been duly executed
and delivered by GDSC and is binding upon and enforceable against GDSC in
accordance with its terms, except as enforceability may be limited or affected
by applicable bankruptcy, insolvency, reorganization, or other laws of general
application relating to or affecting creditors' rights generally and except as
enforceability may be limited by rules of law governing specific performance,
injunctive relief or other equitable remedies.

     2.02 Compliance. The execution, delivery and performance of this Agreement
by GDSC, the compliance by GDSC with the provisions of this Agreement and the
consummation of the transactions described in this Agreement will not conflict
with or result in the breach of any of the terms or provisions of or constitute
a default under:

          2.02-1 the articles of incorporation or bylaws of GDSC;

          2.02-2 any note, indenture, mortgage, deed of trust, loan agreement,
lease or other agreement or instrument to which GDSC is a party or by which GDSC
is bound; or

          2.02-3 any statute or any order, rule, regulation or decision of any
court or regulatory authority or governmental body applicable to GDSC.

     2.03 Consents. Except for the consent of GDSC's principal bank, no consent,

                                        3
<PAGE>
     2.04 Accuracy of Representations & Warranties. None of the representations
or warranties of GDSC contains or will contain any untrue statement of any
material fact or omits or misstates a material fact necessary to make the
statements contained in this Agreement not misleading. GDSC does not know of any
fact that has resulted or that, in the reasonable judgment of GDSC will result,
in any material adverse change in GDSC's business, results of operation,
financial condition or prospects that has not been set forth in this Agreement.

     2.05 Investment Representations. GDSC is acquiring the Purchased CDC Shares
for investment for its own account, and not with a view to, or for resale in
connection with, any distribution of the Purchased CDC Shares. GDSC acknowledges
and understands that the Purchased CDC Shares are being offered and sold without
registration under the Securities Act of 1933, as amended ("1933 Act"), or any
state securities laws based on exemptions provided under such laws, and that the
representations contained in this Agreement are being relied upon by
Shareholders in connection with those exemptions. GDSC further acknowledges and
agrees that the Purchased CDC Shares are "restricted securities" under federal
securities laws and as such may not be sold or disposed of unless they are
registered under the 1933 Act and all applicable state securities laws or
unless, in the opinion of counsel acceptable to shareholders, exemptions from
the registration requirements of the 1933 Act and all applicable state
securities laws are available. GDSC confirms that it has knowledge and
experience in financial and business matters, is capable of evaluating the
merits and risks of an investment in the Purchased CDC Shares, and can bear the
economic risk of an investment in such shares.

     2.06 Reliance. GDSC recognizes and agrees that, notwithstanding any
investigation by Shareholders, Shareholders are relying upon the representations
and warranties made by GDSC in this Agreement.


                                   ARTICLE III

             Representations and Warranties of CDC and Shareholders

     As used in this Agreement, "Material Adverse Effect" means a material
adverse effect on the business, results of operations, financial position,
assets or prospects of CDC, which shall in any event include any adverse effect
on the assets, revenue or net income of CDC in excess of $50,000; and "Material
Adverse Change" means any change that has resulted, will result or is likely to
result in a Material Adverse Effect. CDC and Shareholders represent and warrant
to GDSC as follows:

     3.01 Corporate Existence; Authority. CDC is a corporation duly organized,
validly existing and in good standing under the laws of the State of Oregon, and
CDC has all necessary corporate power and authority to own, lease and operate
its properties and assets and to carry on its business as now conducted and as

stock of CDC. Prior to the Redemption, the outstanding stock of CDC consists of
1,000 shares of common stock, of which 501 shares are held by Dr. Harlow and 499
shares are held by Mr. Jackson. The shares of CDC common stock owned by
Shareholders are owned beneficially and of record, free and clear of all
pledges, security interests, liens, charges, encumbrances, equities, claims,
options or limitations, including limitations affecting Shareholders' ability to
vote the shares.


                                        4
<PAGE>
Neither CDC nor any Shareholder is party to any subscription, option, warrant,
call, right, agreement or commitment (including any right of conversion or
exchange under any outstanding security or other instrument) relating to the
issuance, sale, delivery or transfer of any of CDC's capital stock, except for
the Redemption Agreement. CDC has no subsidiaries and, except for its
partnership interest in Exceptional Needs Dental Service, has no investments in
any corporation, partnership, association, joint venture or other entity. CDC
has full power and authority to enter into this Agreement and to carry out its
terms. CDC has taken all corporate action necessary to authorize the execution,
delivery and performance of this Agreement. This Agreement has been duly and
validly executed and delivered by CDC and Shareholders and is binding upon and
enforceable against CDC and Shareholders in accordance with its terms, except as
enforceability may be limited or affected by applicable bankruptcy, insolvency,
reorganization or other laws of general application relating to or affecting the
rights of creditors and except as enforceability may be limited by rules of law
governing specific performance, injunctive relief or other equitable remedies.

     3.02 No Adverse Consequences. Neither the execution and delivery of this
Agreement by CDC or Shareholders nor the consummation of the transactions
contemplated by this Agreement will

          3.02-1 result in the creation or imposition of any lien, charge or
encumbrance on any of CDC's assets or properties;

          3.02-2 violate or conflict with any provision of CDC's articles of
incorporation or bylaws;

          3.02-3 violate any law, judgment, order, injunction, decree, rule,
regulation or ruling of any governmental authority applicable to CDC or
Shareholders; or

time or both, conflict with, constitute grounds for termination or acceleration
of, result in the breach of the terms, conditions or provisions of, result in
the loss of any benefit to CDC under or constitute a default under any
agreement, instrument, license or permit to which CDC or Shareholders is a party
or by which either of them is bound.

     3.03 Brokers and Finders. Neither CDC nor Shareholders has employed any
broker, finder or agent or dealt with anyone purporting to act in such capacity
or agreed to pay any brokerage fee, finder's fee or commission with respect to
the transaction contemplated by this Agreement, except that CDC has employed
Torwest Capital. Any fees owing to Torwest Capital by CDC are payable and will
be paid by CDC at or before the Closing. CDC and Shareholders acknowledge and
confirm that any such liability shall not be a liability of CDC or GDSC from and
after the Closing.

     3.04 Litigation. Except as set forth on Schedule 3.04, there is no claim,
litigation, proceeding or investigation of any kind pending or threatened by or
against CDC and, to the best knowledge of CDC and Shareholders, there is no
basis for any such claim, litigation, proceeding or investigation.


                                        5
<PAGE>
     3.05 Compliance with Laws. CDC has at all relevant times conducted its
business in compliance with its articles of incorporation and bylaws and all
applicable laws and regulations. CDC is not in violation of any applicable laws
or regulations, other than violations which singly or in the aggregate do not,
and, with the passage of time will not, have a Material Adverse Effect. CDC is
not subject to any outstanding order, writ, injunction or decree, and CDC has
not been charged with, or threatened with a charge of, a violation of any
provision of federal, state or local law or regulation.

     3.06 Employment Matters.

          3.06-1 Labor Matters

               (a) CDC is not a party or otherwise subject to any collective
bargaining or other agreement governing the wages, hours or terms of employment
of its employees. CDC is and has been in compliance with all applicable laws
regarding employment and employment practices, terms and conditions of
employment, wages and hours and is not and has not been engaged in any unfair
labor practice.

               (b) There is no (1) unfair labor practice complaint against CDC
pending before the National Labor Relations Board or any other governmental
authority, (2) labor strike, slowdown or work stoppage actually occurring or, to
the best of the knowledge of CDC, threatened against him, (3) representation

under collective bargaining agreements applicable to CDC.

               (c) CDC has not experienced any primary work stoppage or other
organized work stoppage involving its employees in the past two years.

          3.06-2 Employee Benefits. Schedule 3.06-2 lists all pension,
retirement, profit sharing, deferred compensation, bonus, commission, incentive,
life insurance, health and disability insurance, hospitalization and all other
employee benefit plans or arrangements (including, without limitation, any
contracts or agreements with trustees, insurance companies or others relating to
any such employee benefit plans or arrangements) established or maintained by
CDC, and complete and accurate copies of all those plans or arrangements have
been provided to GDSC. The employee pension benefit plans (within the meaning of
Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") established and maintained by CDC that are subject to ERISA are listed
separately as ERISA Plans on Schedule 3.06-2 (the "ERISA Plans"). The ERISA
Plans comply with the applicable requirements of ERISA. Each of the ERISA Plans
is qualified under Section 401(a) of the Internal Revenue Code of 1986, as
amended (the "Code") and the related trust is tax-exempt under Section 501(a) of
the Code. No "accumulated funding deficiency" as defined in Section 302(a)(2) of
ERISA or Section 412(a) of the Code exists, or has existed, with respect to any
of the ERISA Plans. The present value of all accrued benefits under each of the
ERISA Plans does not exceed the value of such plan's assets, less all
liabilities other than those attributable to accrued benefits. CDC has no
"potential withdrawal liability," as defined in Section 4201 of ERISA. None of
the ERISA Plans, its related trusts or any trustee, investment manager or
administrator thereof has engaged in a nonexempt "prohibited transaction," as
such term


                                        6
<PAGE>
is defined in Section 406 of ERISA and Section 4975 of the Code. There are not
and have not been any excess deferrals or excess contributions under any ERISA
Plan. Each ERISA Plan is and has been operated and administered in conformance
with the requirements of all applicable laws and regulations, whether or not the
ERISA Plan documents have been amended to reflect such requirements. CDC has no
obligation of any kind (whether under the terms of the ERISA Plans or under any
understanding with employees) to make payments under, or to pay contributions to
or in respect of, any plan or arrangement listed on Schedule 3.06-2, or any
other plan, agreement or other arrangement for deferred compensation of
employees, whether or not tax qualified, including, without limitation, a single
employer tax qualified plan, a tax qualified plan of a controlled group of
corporations, a multi-employer pension plan, a nonqualified deferred

     3.17 Status of Contracts and Leases.

          3.17-1 Each of the Contracts and Leases listed on Schedules 3.15 and
3.16 is valid, binding and enforceable by CDC in accordance with its terms and
is in full force and effect, except as enforceability may be limited or affected
by applicable bankruptcy, insolvency, reorganization, or other laws of general
application relating to or affecting creditors' rights generally and except as
enforceability may be limited by rules of law governing specific performance,
injunctive relief or other equitable remedies. There is no existing default or
violation by CDC under any Contract or Lease and no event has occurred which
(whether with or without notice, lapse of time or both) would constitute a
default of CDC under any Contract or Lease. There is no pending or threatened
proceeding which would interfere with the quiet enjoyment of any Real Property
of which CDC is lessee or sublessee.

          3.17-2 All other parties to the Contracts and Leases have consented or
prior to the Closing will have consented (where such consent is necessary) to
the consummation of the transaction contemplated by this Agreement without
requiring modification of CDC's rights or obligations under any Contract or
Lease.

          3.17-3 CDC is not aware of any default by any other party to any
Contract or Lease or of any event which (whether with or without notice, lapse
of time or both) would constitute a default by any other party with respect to
obligations of that party under any Contract or Lease, and, to the actual
knowledge of CDC, there are no facts that exist indicating that any of the
Contracts or Leases may be totally or partially terminated or suspended by the
other parties.

          3.17-4 CDC is not a party to, nor is it bound by, any contract or
agreement that CDC can reasonably foresee will result in any material loss to
CDC upon the performance thereof (including any material liability for penalties
or damages, whether liquidated, direct, indirect, incidental or consequential),
unless such contract or agreement is terminable by CDC on 60 or fewer days
notice at any time without penalty.

     3.18 Title and Condition of Tangible Assets.

          3.18-1 CDC owns all of the Tangible Personal Property except the

               (b) liens for taxes not yet due or being contested in good faith
(and for which adequate accruals or reserves have been established on the
Current Balance Sheet).

Property except the leased property.

          3.18-3 All Tangible Personal Property has been maintained and operated
in accordance with manufacturer's specifications and prudent industry practices,
is in a good state of maintenance and repair, ordinary wear and tear excepted,
and is adequate for the conduct of CDC's business.

          3.18-4 There are no developments affecting any of the Real Property or
Tangible Personal Property pending or, to the actual knowledge of CDC,
threatened which might materially detract from the value of such property or
assets, materially interfere with any present or intended use of any such
property or assets or materially adversely affect the marketability of such
properties or assets.

     3.19 Insurance. Schedule 3.19 contains a complete and accurate list of all
policies of malpractice, liability, fire, worker's compensation and other forms
of insurance insuring CDC and its employees, assets or operations (the
"Policies"). All the Policies are valid, enforceable and in full force and
effect, all premiums with respect to the Policies covering all periods up to and
including the date as of which this representation is being made have been paid
and no notice of cancellation or termination has been received with respect to
any Policy. The Policies are sufficient for compliance with all requirements of
law and of agreements to which CDC is a party and provide insurance for the
risks and in the amounts and types of coverage usually obtained by persons using
or holding similar properties in similar businesses. There are no unresolved
claims for insurance payment under any of the Policies. True and complete copies
of the Policies and all endorsements thereto have been delivered to GDSC. Except
as set forth on Schedule 3.19, CDC has not been refused any insurance coverage

collected and, to the extent required, have been paid to the proper taxing
authority.

passage of time or both, would not have a Material Adverse Effect. CDC and
Shareholders are in compliance with all the terms of each Permit, and there are
no claims of violation by CDC or Shareholders of any Permit.

     3.23 Certain Payments. Neither CDC nor any other person or entity has,
directly or indirectly, on behalf of or with respect to CDC or its operations

corporation (within the meaning of Section 1361(a)(2) of the Code) is less than
$162,937, then

               (a) Shareholders agree to file individual federal and Oregon
income tax returns, including amended returns, reflecting such determination by
including in income their respective pro rata portion of the IBNR adjustment
that passed though to Shareholders with respect to any period in which CDC was
an S corporation during 1998 and to pay all taxes resulting therefrom; and

               (b) CDC shall promptly pay to the Shareholders, pro rata in
proportion to their stock ownership in CDC immediately prior to the Closing, an
amount equal to the sum of (a) 31.76% of the amount by which $162,937 exceeds
the amount includible in CDC's federal taxable income and (b) 6.6% of the amount
by which $162,937 exceeds the amount includible in CDC's Oregon taxable income.
Any such payment shall be treated as a Purchase Price adjustment.

If it is finally determined for federal tax purposes that the IBNR adjustment
amount includible in income by CDC for any period in 1998 in which CDC is a C
corporation or for any later period is more than $162,937, then Shareholders
shall promptly pay to CDC, pro rata in proportion to their stock ownership in
CDC immediately prior to the Closing, an amount equal to 38.36% of the amount by
which the amount includible in CDC's federal taxable income exceeds $162,937.
Any such payment shall be treated as a Purchase Price adjustment.

          5.04-2 Payment of Tax Refunds. Pursuant to the Redemption Agreement,
CDC has assigned to Shareholders the aggregate cumulative refunds receivable by
CDC from the Service and the Oregon Department of Revenue (the "Department") for
federal and Oregon taxable years ended December 31, 1995, 1996, and 1997, and
CDC has agreed promptly to remit to Shareholders any such refunds actually
received from the Service or the Department. In the event the assignment of
refunds receivable is not valid for any reason, GDSC agrees to cause CDC
nevertheless to remit to Shareholders any such refunds actually received from
the Service or the Department. Conversely, if the anticipated settlement with
the Service is not finally agreed to by the Service and, as a result, it is
finally determined that CDC is required to pay any additional federal or Oregon
income tax for the taxable years ended December 31, 1995, 1996, and 1997, then
Shareholders shall promptly pay to CDC, pro rata in proportion to their stock
ownership in CDC immediately prior to the Closing, an amount equal to all such
additional tax. Any such payment shall be treated as a Purchase Price
adjustment.

          5.04-3 CDC Gain on Redemption. Shareholders agree to treat any and all
income or gain recognized by CDC in connection with the distribution of property
to Shareholders pursuant to the Redemption Agreement as income or gain properly
allocable to the period in 1998 during which CDC was an S corporation (within
the meaning of Section 1361(a)(1) of the Code) and to report any and all such
income or gain on their individual federal and Oregon tax returns in accordance
with Section 1366 of the Code and corresponding provisions of ORS chapters 314
and


                                       17
<PAGE>
316. In the event it is finally determined for federal or any state tax purpose
that any income or gain recognized in connection with the Redemption is properly
includible in taxable income of CDC for any period in which CDC is a C
corporation, the Shareholders shall pay to CDC, promptly after demand by CDC, an
amount equal to CDC's tax liability resulting from the income or gain. For
purposes of determining the tax liability, it shall be conclusively presumed
that CDC will incur federal tax liability at a rate of 31.76% (which takes into
account the deductibility of state tax for purposes of computing federal taxable
income) and that CDC will incur state tax liability at a rate of 6.6%. Any such
payment to CDC shall be treated as a Purchase Price adjustment.

          5.04-4 Tax Compliance Costs. Shareholders agree to bear all reasonable
out-of-pocket costs and expenses incurred by CDC or GDSC, including without
limitation attorneys' fees and accountants' fees, associated with the settlement
of IBNR matters, income or gain resulting to CDC as a result of any distribution
pursuant to the Redemption Agreement, or as a result of any other tax matters
relating to periods prior to the Closing, including the filing of CDC's tax
returns for the portion of 1998 prior to the Closing. Costs and expenses
associated with such matters shall include, without limitation, finalizing any
closing agreement, filing returns and amended returns, and responding to audits
and disputes with taxing authorities.

          5.04-5 Cooperation on Tax Matters. GDSC agrees to use its reasonable
best efforts to cause CDC to obtain a closing agreement on Form 906-c and to
prepare and file amended federal and Oregon tax returns for CDC's taxable years
ended December 31, 1995, 1996 and 1997, all in a manner consistent, to the
extent permissible pursuant to the closing agreement as executed by the Service,
with the Form 906-c signed on behalf of CDC and the projections prepared by
Brenner & Company LLP, in each case as previously provided by CDC to GDSC.
Subject to Section 5.04-4, GDSC agrees to cause CDC to continue to retain Lane
Powell Spears Lubersky LLP and Brenner & Company LLP for work associated with
the determination of the proper tax liability, including the closing agreement
and the amended federal and Oregon tax returns, for CDC's taxable years ended
December 31, 1995, 1996 and 1997. In connection with any tax return, audit, or
dispute relating to IBNR adjustments or to gain incurred by CDC in connection
with the Redemption Agreement or otherwise related to tax matters in periods
prior to the Closing, GDSC, on the one hand, and Shareholders, on the other
hand, each agree to:

     (a) assist in all reasonable respects the other party in preparing any tax
return that the other party is responsible for preparing and filing;

     (b) cooperate in all reasonable respects in preparing for any audits of, or
disputes with taxing authorities regarding, any tax return;

     (c) make available to the other and to any taxing authority as reasonably
requested all information, records, and documents relating to such matters;

     (d) provide timely notice to the other in writing of any pending or
threatened tax audits or assessments for taxable periods for which the other may
have tax or indemnification liability; and

     (e) furnish the other with copies of all correspondence received from any
taxing authority in connection with any tax audit or information request with
respect to such matters.

                                   Termination

     8.01 Right of Parties to Terminate. This Agreement may be terminated:

          8.01-1 by GDSC, if any of the authorizations, consents, approvals,
filings or registrations described in Section 6.01 hereof shall have been
denied, not permitted to go into effect or obtained on terms not reasonably

made in this Agreement or in any schedule, certificate or assignment delivered

months following the Closing and after such period shall be terminated and

     9.02 Indemnification by Shareholders.

          9.02-1 Notwithstanding any investigation by GDSC, from and after the
Closing, Shareholders shall indemnify, hold harmless and, to the extent provided
in Section 9.04-1, defend GDSC, its subsidiaries, shareholders, affiliates,
officers, directors, employees, agents, successors and assigns (collectively,
including GDSC, "GDSC's Indemnified Persons") from and against, and reimburse
each of GDSC's Indemnified Persons with respect to, any and all losses, damages,
liabilities, costs and expenses, including interest from the date of such loss
to the time of payment, penalties and reasonable attorneys' fees (collectively,
"Damages") incurred by any of GDSC's Indemnified Persons by reason of or arising
out of or in connection with:

               (a) any breach or inaccuracy of any representation or warranty of
CDC or Shareholders made in this Agreement or any Related Document; or

               (b) any failure by CDC or Shareholders to perform any covenant
required to be performed by them pursuant to this Agreement or any Related
Document.

          9.02-2 This indemnification extends to any Damages suffered by any of
GDSC's Indemnified Persons, whether or not a claim is made against any of GDSC's
Indemnified Persons by any third party.

     9.03 Indemnification by GDSC.

          9.03-1 Notwithstanding any investigation by Shareholders, from and
after the Closing, GDSC shall indemnify, hold harmless and, to the extent
provided in Section 9.04-1, defend Shareholders from and against, and reimburse
Shareholders with respect to, any and all Damages incurred by Shareholders by
reason of or arising out of or in connection with:

               (a) any breach or inaccuracy of any representation or warranty of
GDSC made in this Agreement or any Related Document; or

               (b) any failure by GDSC to perform any covenant required to be
performed by it pursuant to this Agreement or any Related Document.

          9.03-2 This indemnification extends to any Damages suffered by
Shareholders whether or not a claim is made against Shareholders by any third
party.

     9.04 Indemnification Procedure.

          9.04-1 Third Party Claims.

               (a) Each indemnified party shall, with reasonable promptness
after obtaining knowledge thereof, provide any indemnifying party against whom a
claim for indemnification is to be made under this Article 9 with written notice
of all third party actions, suits, proceedings, claims, demands or assessments
that may be subject to the indemnification provisions


                                       22
<PAGE>
of this Article 9 (collectively, "Third Party Claims"), including, in reasonable
detail, the basis for the claim, the nature of Damages and a good faith estimate
of the amount of Damages.

               (b) Each indemnifying party shall have 15 days after its receipt
of the claim notice to notify the indemnified party in writing whether the
indemnifying party agrees that the claim is subject to this Article 9 and, if
so, whether the indemnifying party elects, jointly with any other indemnifying
party notified under Section 9.04-1(a), to undertake, conduct and control,
through counsel of its or their choosing (subject to the consent of the
indemnified party, such consent not to be withheld unreasonably) and at its or
their sole risk and expense, the good faith settlement or defense of the Third
Party Claim.

               (c) If within 15 days after its receipt of the claim notice an
indemnifying party notifies the indemnified party that it elects to undertake
the good faith settlement or defense of the Third Party Claim, the indemnified
party shall cooperate reasonably with the indemnifying party in connection
therewith including, without limitation, by making available to the indemnifying
party all relevant information material to the defense of the Third Party Claim.
The indemnified party shall be entitled to participate in the settlement or
defense of the Third Party Claim through counsel chosen by the indemnified
party, at its expense, and to approve any proposed settlement that would impose
any obligation or duty on the indemnified party, which approval may, in the sole
discretion of the indemnified party, be withheld. So long as an indemnifying
party is contesting the Third Party Claim in good faith and with reasonable
diligence, the indemnified party shall not pay or settle the Third Party Claim.
Notwithstanding the foregoing, the indemnified party shall have the right to pay
or settle any Third Party Claim at any time, provided that in such event it
waives any right to indemnification therefor by the indemnifying party.

               (d) If an indemnifying party does not provide notice that it
elects to undertake the good faith settlement or defense of the Third Party
Claim, or if an indemnifying party fails to contest the Third Party Claim or
undertake or approve settlement, in good faith and with reasonable diligence,
the indemnified party shall thereafter have the right to contest, settle or
compromise the Third Party Claim in good faith at its exclusive discretion, at
the risk and expense of the indemnifying party, and the indemnifying party will
thereby waive any claim, defense or argument that the indemnified party's
settlement or defense of such Third Party Claim is in any respect inadequate or
unreasonable.

               (e) A party's failure to give timely notice will not constitute a
defense, in part or in whole, to any claim for indemnification by such party,
except if, and only to the extent that, such failure results in any material
prejudice to the indemnifying party.

          9.04-2 Non-Third Party Claims.

               (a) Each indemnified party shall, with reasonable promptness,
deliver to any indemnifying party against whom a claim for indemnification is to
be made under this Article 9 written notice of all claims for indemnification
under this Article 9, other than Third Party Claims, including, in reasonable
detail, the basis for the claim, the nature of Damages and a good faith estimate
of the amount of Damages.


                                       23
<PAGE>
               (b) Each indemnifying party shall have 30 days after its receipt
of the claim notice to notify the indemnified party in writing whether the
indemnifying party accepts liability for all or any part of the Damages
described in the claim notice. If the indemnifying party does not so notify the
indemnified party, the indemnifying party shall be deemed to accept liability
for all the Damages described in the claim notice.

               (c) A party's failure to give timely notice will not constitute a
defense, in part or in whole, to any claim for indemnification by such party,
except if, and only to the extent that, such failure results in any material
prejudice to the indemnifying party.

     9.05 Right of Offset. At the election of GDSC, any liability of
Shareholders under Section 9.02 which has been established by agreement,
litigation or in accordance with the procedure set forth in Section 9.04 may be
satisfied by offsetting such liability against the outstanding principal and
interest balance payable under the Promissory Note or against any Earnout
Payment (as defined in the DMO Agreement) payable under the DMO Agreement that
is then due or that subsequently becomes due; provided, however, that if
Shareholders give notice to GDSC within 30 days after Shareholders receives a
notice of claim under Section 9.04-1(a) or 9.04-2(a) of this Agreement that
Shareholders contest their liability for such claim, GDSC may not exercise its
right of offset until the procedure described in Section 9.06 of the DMO
Agreement has been completed.

     9.06 Limitations.

          9.06-1 Any amounts payable under Section 9.02 or 9.03 or this Section
shall be treated by GDSC and Shareholders as an adjustment to the Purchase
Price, and shall be calculated after giving effect to (i) any proceeds received
from insurance policies covering the Damages that are the subject of the
indemnification, and (ii) the actual recognized tax benefit to the indemnified
party resulting from the Damages that are the subject of the indemnification;
provided that to the extent that any tax benefit is recognized in a tax year
later than the year in which the indemnification payment is made, no adjustment
for tax benefit shall be made in determining the amount of the indemnification
payment and the indemnified party shall make a payment to the indemnifying party
in an amount of such recognized tax benefit in the year in which it is realized.
For purposes of this Section 9.06-1, an actual recognized tax benefit is an
actual reduction in taxes payable or a refund of taxes previously paid.

          9.06-2 The indemnification obligations set forth in Sections 9.02 and
9.03 of this Agreement and Sections 9.02 and 9.03 of the DMO Agreement with
respect to breaches of representations or warranties shall not apply unless the
total amount of Damages with respect to such breaches incurred either by GDSC's
Indemnified Persons or by DMO and/or Shareholders (as the case may be) exceeds
$200,000 in the aggregate, as a result of all matters giving rise to rights to
indemnification for such breaches under those Sections. In the event that the
amount of such Damages exceeds that threshold, GDSC's Indemnified Persons or DMO
and Shareholders (as the case may be) shall be entitled to indemnification for
the full amount of all such Damages to the extent that the full amount of all
such Damages exceeds $100,000, subject to Section 9.06-3.

          9.06-3 The right of GDSC's Indemnified Persons to seek indemnification
from DMO and/or Shareholders under this Agreement or the DMO Agreement shall
terminate the sooner of (a)


                                       24
<PAGE>
39 months after the Closing Date or (b) with respect to claims under Section
9.04-2 of this Agreement and Section 9.04-2 of the DMO Agreement, at such time
as the total Damages paid by DMO and/or Shareholders in respect of such claims
(whether or not paid by offset of amounts owed to DMO or Shareholders) reaches a
total of $5,000,000.00 or (c) with respect to all claims, at such time as the
total Damages paid by DMO and/or Shareholders in respect of such claims (whether
or not paid by offset of amounts owed to DMO or Shareholders) reaches a total
equal to the full amount of the Purchase Price under this Agreement and the DMO
Agreement.

     9.07 Exclusive Rights. An indemnified party's rights to indemnification
under this Article 9 shall be the exclusive remedy in the event of any breach of
any representation or warranty under this Agreement.

statements as required by governmental authority or in order for a party to
satisfy its legal obligations (prompt notice of which shall in any such case be
given to the other party or parties).
