The first payment of Earnout Consideration shall also include the amount equal to (a) 4.48 multiplied by the Orange EBITDA for the first 12 months of the Earnout Period, reduced by (b) the sum of the Orange Cash Consideration Amount (as defined below) and the Orange Earnout Consideration (as defined below). The second payment of Earnout Consideration shall equal (a) .96 multiplied by the EBITDA for the second 12 months of the Earnout Period, plus (b) .06 multiplied by the Orange EBITDA for the second 12 months of the Earnout Period, reduced by (c) 80% of the earnout consideration, if any, paid by GD Sub under the terms of the Asset Purchase Agreement dated June 30, 1998 between GDSC, GD Sub and Bryan Watanabe D.D.S., Inc. The third payment of Earnout Consideration shall equal (a) .96 multiplied by the EBITDA for the third 12 months of the Earnout Period, plus (b) .06 multiplied by the Orange EBITDA for the third 12 months of the Earnout Period.

The "Excess Cap-ex Charge" shall be an annual charge equal to 25% of the total accumulated capital expenditures by GD Sub at the Dental Practices after the Closing Date which in any 12-month period exceeds 2% of the combined net revenue of the Dental Practices for such period. The "Admin Charge" shall equal a pro rata portion of the sum of (a) rent reimbursed by GD Sub to PDS for the Administrative Office, and (b) all unreimbursed costs incurred by GD Sub at the Administrative Office, including but not limited to employee compensation and benefits, based on the ratio of the combined net revenue of the Dental Practices to the combined net revenue of all dental practices managed by GD Sub from the Administrative Office for the relevant period.

The remaining 20% of the first payment of Earnout Consideration shall be paid in shares of GDSC Common Stock. To determine the number of shares of GDSC Common Stock to be issued as part of the first payment of Earnout Consideration, a share of GDSC Common Stock shall be valued at the average of the closing prices of GDSC Common Stock reported by NASDAQ for the five trading days prior to the 60th day after the end of the first 12 months of the Earnout Period. All of the second and third payments of Earnout Consideration shall be paid by check. The calculation and payment of each payment of Earnout Consideration shall be completed within 90 days of the completion of the applicable 12-month portion of the Earnout Period. 1.05 Purchase Price Adjustment.

If the amount of Net Current Assets is $55,000 more or less than $365,000, the Cash Consideration shall be adjusted by the full amount of the difference (the "Purchase Price Adjustment"). If the difference between Net Current Assets and $365,000 does not exceed $55,000, there shall be no Purchase Price Adjustment. 1.05-2 If the Net Current Assets are greater than $420,000, the Purchase Price Adjustment shall be paid to PDS by check within 10 days after PDS delivers the certificate described in Section 1.05-4.

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 PDS 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 PDS that are subject to ERISA are listed separately as ERISA Plans on Schedule 3.06-2 (the "ERISA Plans"). The ERISA Plans comply 11 with the applicable requirements of ERISA. PDS has received from the Internal Revenue Service a favorable determination for each of the ERISA Plans and their related trusts that 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. There has been no event subsequent to that determination that has adversely affected the tax qualified status of the ERISA Plans or the exemption of the related trusts other than changes in the Code that are not effective as of the Closing Date. 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. PDS 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. PDS 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.

Schedule 3.06-3 lists and includes all of PDS'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. PDS does not have any agreements or understandings with PDS's employees except as reflected in the items listed in Schedules 3.06-2 and 3.06-3. 3.06-4 Compensation.

Schedule 3.08 separately lists all receivables of PDS and Orange Dental Services from the Dental Practices and the Orange Dental Practice or otherwise (including management fees receivable, accounts receivable, loans receivable and advances) as of March 31, 1998. Each of the receivables listed on Schedule 3.08, and each of the receivables that has arisen since March 31, 1998 has arisen only from bona fide transactions in the ordinary course of business and is not subject to any offset or counterclaim. 3.09 Prepaid Expenses and Other. Schedule 3.09 lists all prepaid expenses and deferred charges of PDS, Orange Dental Services or the Dental Practices, and each of them, reflected on the Current Balance Sheets as well as the items included in the Other Assets line, if any, on the Current Balance Sheets. 3.10 Personal Property.

For each item of indebtedness, Schedule 3.12 shows the name of lender and the principal balance. 3.13 Other Liabilities. Except as listed on Schedule 3.13, neither PDS nor any Professional Corporation has any liability or obligation (whether absolute, accrued, contingent or other, and whether due or to become due), which is not accrued, reserved against or disclosed in the Current Balance Sheets, other than liabilities incurred in the ordinary course of business consistent with past practice, which individually or in the aggregate would not have a Material Adverse Effect. 3.14 Absence of Certain Changes or Events. Since the date of the Current Balance Sheets, there has not been with respect to PDS, the Dental Practices or any of them: 13 3.14-1 Any Material Adverse Change or any event, occurrence, development or state of circumstances or facts which could reasonably be expected to result in a Material Adverse Change; 3.14-2 Any damage, destruction or casualty loss, whether insured against or not, to any assets or properties associated with any of the Dental Practices; 3.14-3 Any increase in the rate or terms of compensation payable or to become payable by PDS to its key employees; any increase in the rate or terms of any bonus, insurance, pension or other employee benefit plan, payment or arrangement made to, for or with any such key employees; any special bonus or remuneration paid; or any written employment contract executed or amended; 3.14-4 Any entry into any agreement, commitment or transaction (including, without limitation, any borrowing, capital expenditure or capital financing or any amendment, modification or termination of any existing agreement, commitment or transaction) by PDS or any Professional Corporation, except agreements, commitments or transactions in the ordinary course of business and consistent with past practices or as expressly contemplated in this Agreement; 3.14-5 Any conduct of business which is outside the ordinary course of business or not substantially in the manner that PDS previously provided management services to the Dental Practices; 3.14-6 Any purchase or other acquisition of property, any sale, lease or other disposition of property, or any expenditure, except in the ordinary course of business; 3.14-7 Any incurrence of any noncontract liability which, either singly or in the aggregate is material to the business, results of operations, financial condition or prospects of any of the Dental Practices; 3.14-8 Any encumbrance or consent to encumbrance of any property or assets of PDS except in the ordinary course of business; or 3.14-9 Any change in the assets, liabilities, licenses, permits or franchises of PDS, or in any agreement to which PDS is a party or is bound, which has had or reasonably could be expected to have a Material Adverse Effect. 3.15 Leases.

PDS and Shareholders acknowledge and understand that the Shares are being offered and sold without registration under the 1933 Act or any state securities law based on exemptions provided under such laws, and that the representations contained in this Agreement are being relied upon by GD Sub and GDSC in connection with those exemptions. PDS and Shareholders further acknowledge and agree that the 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 GD Sub and GDSC, exemptions from the registration requirements of the 1933 Act and all applicable state securities laws are available. In this regard, PDS and Shareholders acknowledge that GDSC is under no obligation to register the Shares, that the Shares will not be eligible for resale in the public market pursuant to Rule 144 under the 1933 Act until one year after the Closing Date, and that PDS and Shareholders will bear the economic risk of ownership of the Shares at least until that time. PDS and Shareholders consent to having appropriate legends placed on the certificates representing the Shares relating to this restriction on transfer. 3.28 Access to Information.

(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. 28 (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 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 or not 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. 29 9.05 Right of Offset. At the election of GD Sub, any liability of PDS or any Shareholder 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 any Earnout Consideration then due or that subsequently becomes due. For this purpose, a liability shall not be deemed to have been established in accordance with the procedure set forth in Section 9.04 if PDS or the Shareholder has asserted under Section 9.04-1(b) that the liability is not subject to this Article 9 and the question has not been resolved by agreement or litigation. 9.06 Rights Not Exclusive. An indemnified party's rights to indemnification under this Article 9 are in addition to, and not in lieu of, any other rights to which the indemnified party may be entitled at law or in equity.
