GDSC and GMS shall execute a Certificate of Merger to be filed with the Secretary of State of the State of Delaware and Articles of Merger to be filed with the Secretary of State of the State of Washington, both on the Closing Date, as defined in Section 1.05 or as soon thereafter as practicable.

The manner and basis of converting the GMS Stock and outstanding rights to acquire GMS Stock into GDSC Common Stock and rights to acquire GDSC Common Stock are as follows: 1.04-1 GMS Stock. Each share of GMS Stock outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and become a number of shares of GDSC Common Stock determined pursuant to this Section 1.04-1. (a) As conditions to the Merger, the following actions shall take effect in the following order immediately prior to the Effective Time: (i) Pursuant to the consent of the holders of at least a majority of the outstanding shares of Series A Preferred Stock of GMS ("GMS Series A Preferred Stock") and Series B-1 Preferred Stock of GMS ("GMS Series B-1 Preferred Stock") (counted together as a single class), each outstanding share of GMS Series A Preferred Stock and GMS Series B-1 Preferred Stock shall be converted into one share of Common Stock of GMS ("GMS Common Stock"). (ii) Pursuant to resolutions adopted by the Board of Directors of GMS and the consent of all holders of GMS Series B-1 Preferred Stock, all accrued and unpaid cumulative dividends on the GMS Series B-1 Preferred Stock shall be paid in shares of GMS Common Stock. To determine the number of shares of GMS Common Stock to be issued to a holder of GMS Series B-1 Preferred Stock in payment of such accrued and unpaid cumulative dividends, the amount of accrued and unpaid cumulative dividends owed to such holder through the Effective Time shall be divided by the product of .45 multiplied by the GDSC Common Stock Value. For purposes of this Agreement, the "GDSC Common Stock Value" means the average of the daily closing prices of the GDSC Common Stock on the Nasdaq Small Cap Market during the 30- calendar day period ending three calendar days prior to the Closing Date, multiplied by .95. (iii) Pursuant to subsection 4(b)(ii) of Article IV.B. of the Restated Certificate of Incorporation of GMS, each outstanding share of Series C Preferred 3 Stock of GMS ("GMS Series C Preferred Stock") shall be converted into a number of shares of GMS Common Stock determined as follows: (A) The "Total Purchase Price" shall be determined by multiplying 4,542,326 by the GDSC Common Stock Value. (B) The "Pre-C Fully Diluted Common Stock" shall equal the number of outstanding shares of GMS Common Stock (including the shares issued under subparagraphs (i) and (ii) above) assuming (x) the conversion into or exchange for GMS Common Stock of all, if any, remaining securities of GMS that are convertible into or exchangeable for GMS Common Stock other than shares of GMS Series C Preferred Stock, and (y) the exercise of all outstanding options, warrants or other rights to acquire GMS Common Stock or securities which are exercisable for or convertible into GMS Common Stock, whether or not then exercisable. (C) The "Fully Diluted Series C Shares" shall equal the sum of the number of outstanding shares of GMS Series C Preferred Stock and the maximum number of shares of GMS Series C Preferred Stock issuable under all outstanding contingent or other rights to receive such stock. For this purpose, the maximum number of shares of GMS Series C Preferred Stock issuable pursuant to the merger of GMS and Premier Dental Care, an Idaho corporation, shall be 180 shares at closing and 180 shares pursuant to contingent rights. (D) The "Assumed Series C Conversion Shares" shall be determined by dividing the Total Purchase Price by the Pre-C Fully Diluted Common Stock, and then dividing the resulting quotient into the product of $1,000 multiplied by the Fully Diluted Series C Shares. (E) The "Qualified Sale Price" shall be determined by dividing the Total Purchase Price by the sum of the Pre-C Fully Diluted Common Stock and the Assumed Series C Conversion Shares. (F) The number of shares of GMS Common Stock issuable upon conversion of each outstanding share of GMS Series C Preferred Stock shall equal $1,000 divided by 75% of the Qualified Sale Price, with the number of shares of GMS Common Stock issuable to each holder of GMS Series C Preferred Stock being rounded to the nearest whole share. (b) After the occurrence of the events referred to in subparagraph (a) above, the only outstanding shares of GMS Stock shall be shares of GMS Common Stock and each such outstanding share of GMS Common Stock shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and become a number of shares of GDSC Common Stock determined by multiplying the number of shares of GMS Common Stock by the Conversion Ratio. For purposes of this 4 Agreement, the "Conversion Ratio" equals 4,251,089 divided by the difference determined by subtracting 667,450 from the number of shares of GMS Common Stock outstanding at the Effective Time. For this purpose, GMS Common Stock outstanding at the Effective Time shall include shares of GMS Common Stock issuable upon conversion of the shares of GMS Series C Preferred Stock to be issued at the closing of the merger of GMS and Premier Dental Care, an Idaho corporation, whether or not that closing shall have occurred prior to the Effective Time. (c) No fractional shares of GDSC Common Stock shall be issued in the Merger. Any fractional share otherwise issuable shall be rounded to nearest whole share. 1.04-2 GMS Options and Warrants. Each option or warrant to purchase shares of GMS Common Stock outstanding at the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be assumed by GDSC and shall be converted at the Effective Time into and become an option to purchase the number of shares of GDSC Common Stock determined by multiplying the number of shares of GMS Common Stock subject to such option or warrant immediately prior to the Effective Time (whether or not such option or warrant shall then have been exercisable) by the Conversion Ratio, and then rounding to the nearest whole number. The exercise price per share of such options and warrants shall be adjusted to the number determined by dividing the per share exercise price of such option or warrant as in effect immediately prior to the Effective Time by the Conversion Ratio. The term, exercisability, vesting schedule, status as an "Incentive Stock Option" under Section 422 of the Code, if applicable, and all other terms and conditions of the options or warrants will to the extent permitted by law and otherwise reasonably practicable be unchanged; each option which is an Incentive Stock Option shall be adjusted in accordance with the requirements of Section 424(a) of the Code so as not to constitute a modification, renewal or extension of the option within the meaning of Section 424(h) of the Code. 1.04-3 GDSC Common Stock. Each share of GDSC Common Stock outstanding prior to the Merger shall remain outstanding without change subsequent to the Merger and each option or warrant to acquire shares of GDSC Common Stock outstanding prior to the Merger shall remain outstanding without change subsequent to the Merger. 1.04-4 Stock Splits, Etc. If, between the date of this Agreement and the Effective Time, the outstanding shares of GDSC Common Stock shall have been changed into a different number of shares or a different class by reason of any reclassification, combination, recapitalization, stock split, stock dividend, subdivision, exchange of shares, or other extraordinary transaction, the number of shares of GDSC Common Stock to be issued by virtue of the Merger shall be appropriately adjusted. 1.04-5 Surrender of Certificates. After the Effective Time, each shareholder of GMS shall, upon surrender to GDSC of a certificate or certificates 5 representing his shares of GMS Stock, receive in exchange therefor a certificate or certificates representing the number of shares of GDSC Common Stock into which the GMS Stock shall have been converted pursuant to the provisions of Section 1.04-1. Until so surrendered, each certificate which prior to the Merger represented shares of GMS Stock shall be deemed, for all purposes, to evidence ownership of the number of shares of GDSC Common Stock into which the shares of GMS Stock shall have been converted. 1.05 Closing. The consummation of the transactions contemplated by this Agreement (the "Closing") shall take place at the offices of Stoel Rives LLP, Portland, Oregon, at 10:00 a.m., Pacific time, on October 31, 1997 or, if later, at 10:00 a.m., Pacific time, on the date that is 10 business days after the date that all conditions to the Closing are satisfied (other than those conditions that by their terms are to occur at the Closing) or at another date, time and place agreed upon in writing by the parties (the "Closing Date"). 1.06 Subsequent Actions. If, at any time after the Effective Time, GDSC shall consider or be advised that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in GDSC its right, title or interest in, to, or under any of the rights, properties or assets of GMS acquired or to be acquired by GDSC as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, the officers and directors of GDSC shall be authorized to execute and deliver, in the name and on behalf of GMS, or otherwise, all such deeds, bills of sale, assignments and assurances, and to take and do, in the name and on behalf of GMS, or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title and interest in, to and under such rights, properties or assets in GDSC or otherwise to carry out the purposes of this Agreement. ARTICLE II Representations and Warranties of GDSC 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 a party, which shall in any event include any adverse effect on the shareholders' equity, assets, revenue or net income of that party in excess of $250,000; and "Material Adverse Change" means any change that has resulted, will result or is reasonably likely to result in a Material Adverse Effect. As used in this Agreement, "knowledge" means the actual or constructive knowledge of the executive officers and directors of GDSC or GMS (as the context requires). A person is deemed to have constructive knowledge for purposes of this definition of "knowledge" only if he or she would have actual knowledge by reason of conducting reasonable investigation or making reasonable inquiry within the scope of his or her employment or duties. 6 GDSC represents and warrants to GMS as follows: 2.01 Corporate Existence. 2.01-1 GDSC is a corporation duly organized, validly existing and in good standing under the laws of the State of Washington, and GDSC 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 proposed to be conducted.

There is no pending or, to GMS's knowledge, threatened proceeding which would interfere with the quiet enjoyment of any GMS Real Property. 3.14-2 GMS is not aware of any default by any other party to any GMS Contract or GMS 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 GMS Contract or GMS Lease, and, to its knowledge, there are no facts that exist indicating that any of the GMS Contracts or GMS Leases may be totally or partially terminated or suspended by the other parties. 23 3.14-3 GMS is not a party to, nor is it bound by, any contract or agreement that it can reasonably foresee will result in any loss that would have a Material Adverse Effect on GMS upon the performance thereof (including any liability for penalties or damages, whether liquidated, direct, indirect, incidental or consequential that would have a Material Adverse Effect). 3.15 Title and Condition of Tangible Assets. 3.15-1 GMS owns all of its tangible personal property except leased property free and clear of all mortgages, pledges, security interests, claims, charges or other encumbrances or restrictions of any kind, except for liens disclosed on the GMS Current Balance Sheet or liens for taxes not yet due or being contested in good faith (and for which adequate accruals or reserves have been established on the GMS Current Balance Sheet). 3.15-2 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 GMS's business. 3.15-3 There are no developments affecting any of the GMS Real Property or GMS's tangible personal property pending or, to its knowledge, threatened which might detract from the value of such property or assets, interfere with any present or intended use of any such property or assets or adversely affect the marketability of such properties or assets in a manner that GMS could reasonably foresee would have a Material Adverse Effect. 3.16 Insurance. GMS maintains policies of malpractice, liability, fire, worker's compensation, director's and officer's and other forms of insurance insuring GMS, its officers, directors or employees, its assets or its operations (the "GMS Policies") which are valid, enforceable and in full force and effect. All premiums with respect to the GMS 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 GMS Policy. The GMS Policies are sufficient for compliance with all requirements of law and of agreements to which GMS 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. GMS has not been refused any insurance coverage and no insurance coverage has been canceled during the five years preceding the date of this Agreement. 3.17 Taxes. 3.17-1 Returns. GMS has filed all federal, state and other returns, reports and information returns required to be filed by it with respect to Taxes which relate to the 24 business, results of operations or financial condition of GMS (collectively, the "GMS Returns") and has timely paid all Taxes shown to be due on the GMS Returns. GMS has not waived any statute of limitations in respect of Taxes or sought or received any extension of time within which to file any return or report. All GMS Returns filed are complete and accurate in all respects, except where the lack of completeness or accuracy would not have a Material Adverse Effect, and no additional Taxes are owed by GMS with respect to the periods covered by the GMS Returns. 3.17-2 Taxes Paid or Reserved. All deficiencies in Taxes asserted or assessments made by any taxing authority have been fully paid or finally settled. The reserves for Taxes reflected in the GMS Current Balance Sheet are adequate for payment of Taxes with respect to GMS in respect of all periods ending on or before the date of the GMS Current Balance Sheet. All Taxes which GMS has been required to collect or withhold have been withheld or collected and, to the extent required, have been paid to the proper taxing authority. 3.18 Certain Interests. Except as set forth on Schedule 3.18, no shareholder of GMS nor any officer or director of GMS (or any entity owned or controlled by one or more of such parties) (a) has any interest in any property, real or personal, tangible or intangible, used in or pertaining to GMS's business, or (b) is indebted to GMS. GMS is not indebted to any of its shareholders, directors or officers (or any entity owned or controlled by one or more of such parties) except for amounts due under normal salary arrangements and for reimbursement of ordinary business expenses. Except as set forth on Schedule 3.18, the consummation of the transaction contemplated by this Agreement will not (either alone or upon the occurrence of any act or event, or with the lapse of time, or both) result in any payment (severance or other) becoming due from GMS to any of its shareholders, officers, directors, or employees (or any entity owned or controlled by one or more of such parties). 3.19 No Restrictions. No power of attorney or similar authorization given by GMS is presently in effect or outstanding. No contract or agreement to which GMS is a party or is bound or to which any of its properties or assets is subject limits the freedom of GMS to compete in any line of business or with any person. 3.20 Permits and Licenses. Except as set forth on Schedule 3.20, GMS and, to GMS's knowledge, the GMS Professional Corporations hold, and at all times have held, all Permits necessary for the lawful conduct of their respective businesses pursuant to all applicable statutes, laws, ordinances, rules and regulations of all governmental bodies, agencies and other authorities having jurisdiction over them or any part of their operations, except where the failure to hold any Permit, singly or in the aggregate, either alone or with the giving of notice or the passage of time or both, would not have a Material Adverse Effect. GMS and, to GMS's knowledge, the GMS Professional Corporations are in compliance with all the terms of each Permit, and there are no claims of violation by GMS or any GMS Professional Corporation of any Permit. 25 3.21 Certain Payments. No person or entity has, directly or indirectly, on behalf of or with respect to GMS or its business or operations made or received any payment that was not legal to make or receive under federal, state or local laws of the United States or any other country or territory. 3.22 Environmental Conditions.

Complete and accurate copies of such books, records and ledgers have been made available to GDSC. 3.25 Pooling Matters. GMS has not, based on consultation with its independent accountants, taken or agreed to take any action that would prevent the ability of the parties to account for the business combination to be effected by the Merger as a pooling of interests. 3.26 Certain Tax Matters. 3.26-1 Liabilities Incurred in Ordinary Course.

Without making any representations with respect to any information to be supplied by GDSC, the Consent Solicitation and Information Statement to be delivered by GMS to the GMS shareholders in connection with their consideration of this Agreement and the Merger will not contain any untrue statement of a material fact concerning GDSC or the Merger, and will not omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. 3.28 Reliance.

Each party will promptly notify the other by telephone and thereafter confirm in writing, if any such discussions or negotiations are sought to be initiated with, or any such proposal or possible proposal is received by such party. In the event one party receives an unsolicited offer relating to a Competing Transaction, such party shall promptly inform the person making such unsolicited offer of the existence of this Agreement and, subject to Section 9.02(f), shall reject such offer. 9.01-2 The term "Competing Transaction" shall mean any of the following involving either GMS or GDSC, as the case may be (other than the Merger): (i) any merger, consolidation, share exchange, business combination or similar transactions involving such party, or (ii) any sale, lease, exchange, mortgage, pledge, transfer or other 38 disposition of 15% or more of the assets of such party and its subsidiaries, taken as a whole, in a single transaction or series of transactions. The term "Competing Transaction" shall not include (x) the Bakersfield Transaction, or (y) any one or more transactions which, in the aggregate, do not contemplate the issuance of greater than 10% of the outstanding shares of GMS common stock or GDSC Common Stock (assuming issuance of approximately 1.5 million shares of GDSC Common Stock proposed to be issued pursuant to the Bakersfield Transaction). 9.02 Right of Parties to Terminate. This Agreement may be terminated: (a) by GDSC, if any of the authorizations, consents, approvals, filings or registrations described in Section 7.01 hereof shall have been denied, not permitted to go into effect or obtained on terms not reasonably satisfactory to GDSC and all reasonable final appeals shall have been exhausted; (b) by GMS, if any of the authorizations, consents, approvals, filings or registrations described in Section 8.01 hereof shall have been denied, not permitted to go into effect or obtained on terms not reasonably satisfactory to GMS and all reasonable final appeals shall have been exhausted; (c) by GDSC, if GMS shall have breached any of its obligations hereunder in any material respect; (d) by GMS, if GDSC shall have breached any of its obligations hereunder in any material respect; (e) by either GMS or GDSC, by written notice to the other party, if the Closing shall not have occurred on or prior to February 28, 1998; provided, however, that the right to terminate this Agreement under this Section shall not be available to any party whose failure to fulfill or perform any obligation under this Agreement has substantially or materially contributed to the cause of, or resulted in, the failure of the Closing to occur on or before such date; or (f) by either GMS or GDSC in the event that: (i) GMS or GDSC receives an unsolicited written offer from a third party relating to a Competing Transaction (which offer may or may not be subject to confirmatory due diligence) and (ii) such party shall have notified the other party in writing of all terms and conditions of such offer, then thereafter such party shall be entitled to negotiate and provide information to such third party. In addition, in the event that such offer, including the financing thereof, has been determined by the Board of Directors of such party based upon the written opinion of its outside financial advisors to be on terms financially superior for its shareholders than the Merger (a "Bona Fide Offer"), such party may terminate this Agreement and accept such Bona Fide Offer; provided, however, that prior to the termination of this Agreement and the acceptance of such Bona Fide Offer, such party shall have given the other party 48 39 hours written notice of such Bona Fide Offer and of its intention to accept such offer and terminate this Agreement.

If either GDSC or GMS decides to terminate this Agreement pursuant to Section 9.02, such party shall promptly give written notice to the other party to this Agreement of such decision.
