ARTICLE VI

COVENANTS

     Each of the Sellers hereby covenants and promises to Buyer and, where expressly stated, Buyer
hereby covenants and promises to Sellers, the following:

     6.1 Employees. Buyer shall have no obligation to make an offer of employment to any
employee of any Seller. Notwithstanding the preceding sentence, any employee of any Seller hired
by Buyer shall become an employee of Buyer under Buyer’s plans and practices, and shall be subject
to the terms and conditions of Buyer’s plans, including the terms of eligibility. At or prior to
the Closing, each Seller shall pay to its employees all amounts owing to such employees for earned
vacation and sick leave in accordance with such Seller’s current policies. Buyer shall not assume
and shall not be obligated to continue or assume any employee benefit plan or any other type of
employee benefit or compensation plan or arrangement or any employer payroll policy or practice
established, maintained, or contributed to by any Seller. Buyer is not a “successor employer” with
respect to any employee benefit plan of any Seller. Buyer and Sellers agree that the provisions of
this Section 6.1 are solely between and for the benefit of Buyer and Sellers and do not inure to
the benefit of, or confer rights upon, any third party, including any employee of Buyer or any
Seller.

     6.2 Miscellaneous. Each Seller shall retain liability for and such Seller shall
indemnify and hold Buyer harmless against:

17

 

     (A) All claims asserted by third persons for breach of contract, tort,
infringement, violation of law, or other conduct occurring on or before the Closing
Date in connection with the business of such Seller; and

     (B) All claims relating to compliance by such Seller with the applicable
provisions of ERISA, the Code and other applicable laws.

     6.3 Due Diligence Investigation. For the purpose of permitting Buyer and its
representatives to conduct a due diligence review (the “Diligence Review”) of Sellers, each Seller
shall afford Buyer and its representatives full and complete access to the books and records,
financial statements, Tax Returns, facilities, employees and such other information of such Seller
as Buyer may reasonably request to evaluate the business, operations, properties, assets,
Liabilities and prospects of such Seller. In connection with the Diligence Review, representatives
of Buyer shall be entitled to consult with representatives, officers and employees of Sellers. The
Diligence Review and any such consultations shall be conducted in a manner not to unreasonably
interfere with the operation of the respective businesses of Sellers.

     6.4 Confidentiality. Any non-public information furnished to or obtained by Buyer
from Sellers or any of their respective officers, employees, attorneys, accountants or authorized
representatives in connection with the Diligence Review pursuant to Section 6.3 hereof shall be
considered “Evaluation Material.” Evaluation Material shall not include public information or
non-public information obtained by Buyer or its Affiliates or representatives from a third party
who is lawfully in possession of such information and who has the legal right to transmit such
information. In the event that the transactions contemplated by this Agreement are not
consummated, Buyer (i) agrees to return to Sellers all written evaluation materials and copies
thereof furnished by Sellers to Buyer, (ii) agrees to destroy all documents, notes and other work
product derived from the Evaluation Material, and (iii) agrees to promptly confirm in writing to
Sellers the fact of such destruction. Except as otherwise required by law, Buyer agrees to keep
the Evaluation Material confidential, not to use the Evaluation Material for any purpose other than
to the extent contemplated hereby, or permit any such Evaluation Material to be made available to
third parties other than its designated representatives or agents who Buyer will direct to maintain
the Evaluation Material confidential. The obligations of Buyer under the provisions of this
Section 6.4 shall survive for a period of three (3) years after the date of any termination of this
Agreement.

     6.5 Confidential Information. Each of the Sellers will treat and hold as such all of
the Confidential Information, refraining from using any of the Confidential Information except in
connection with this Agreement, and, following the Closing, will deliver promptly to Buyer or
destroy, at the request and option of Buyer, all tangible embodiments (and all copies) of the
Confidential Information which are in its possession. In the event that any Seller is requested or
required (by oral question or request for information or documents in any legal proceeding,
interrogatory, subpoena, civil investigative demand, or similar process) to disclose any
Confidential Information, such Seller will notify Buyer promptly of the request or requirement so
that Buyer may seek an appropriate protective order or waive compliance with the provisions of this
Section 6.5. If, in the absence of a protective order or the receipt of a waiver hereunder, such
Seller is, on the advice of counsel, compelled to disclose any Confidential Information to any
tribunal or governmental agency or else stand libel for contempt, such Seller may disclose

18

 

the Confidential Information to the tribunal or governmental agency; provided, however, that
such Seller shall use commercially reasonable efforts to obtain, at the request and expense of
Buyer, an order or other assurance that confidential treatment will be accorded to such portion of
the Confidential Information required to be disclosed as Buyer shall designate.

shall not dissolve or otherwise terminate its existence as a limited partnership for at least one
(1) year after the Closing Date. But nothing herein shall require a Seller to continue any
operations.

     6.7 Survivability. The provisions of this Article VI shall survive the Closing Date;
provided, however, that in the event that the transactions contemplated hereby are consummated,
Buyer’s obligations under Section 6.4 shall terminate as of the Closing Date.

ARTICLE VII

INDEMNIFICATION

     7.1 Survival of Representations and Warranties. All of the representations and
warranties of the parties contained in this Agreement shall survive the closing of the transactions
contemplated herein for a period of one (1) year. The parties intend to shorten the statute of
limitations and agree that no claims or causes of action of any kind may be brought against any
Seller, the Buyer or any of their respective partners, officers, employees, affiliates, controlling
persons, agents, attorneys, accountants or representatives based upon, directly or indirectly, any
of the representations, warranties, covenants or agreements contained herein after the first
anniversary of the Closing Date. This Section 7.1 shall not limit any covenant or agreement of the
parties which contemplates performance after the Closing including, without limitation, the
covenants and agreements set forth in Article VI hereof, it being understood that all such
covenants and agreements contemplating performance after the Closing shall survive until the
expiration of the applicable statute of limitations.

     7.2 Indemnification by Sellers. Subject to the terms and conditions set forth herein,
each Seller shall severally indemnify and hold harmless Buyer and its members, managers, officers,
employees, attorneys, accountants, and other agents and Affiliates (collectively, the “Buyer
Indemnitees”) in respect of any and all damages, losses, liabilities, payments, obligations,
penalties, claims, litigation, demands, defenses, judgments, suits, proceedings, costs,
disbursements or expenses (including, without limitation, reasonable fees, disbursements and
expenses of attorneys, accountants and other professional advisors) of any kind or nature
whatsoever (collectively “Damages”) incurred by any Buyer Indemnitee as a result of, in connection
with or arising out of:

     (i) Any inaccuracy in or breach of any representation or warranty made by such
Seller herein; or

     (ii) Any breach or nonperformance (partial or total) of any covenant or
agreement of such Seller contained herein.

     7.3 Indemnification by Buyer. Subject to the terms and conditions set forth herein,
Buyer shall indemnify and hold harmless each of the Sellers and their respective partners,
officers, employees, attorneys, accountants and other agents and Affiliates (collectively, the

19

 

“Seller Indemnitees”) in respect of any Damages incurred by any Seller Indemnitee as a result
of, in connection with or arising out of:

     (i) Any inaccuracy in or breach of any representation or warranty made by Buyer
herein; or

     (ii) Any breach or nonperformance (partial or total) of any covenant or
agreement of Buyer contained herein.

     7.4 Third Party Indemnification. The obligations of the Sellers to indemnify the
Buyer Indemnitees under Section 7.2 hereof and the obligations of the Buyer to indemnify the Seller
Indemnitees under Section 7.3 hereof, in each case resulting from the assertion of liability by a
third party (each, as the case may be, a “Claim”), shall be further subject to the following terms
and conditions:

     (i) Any party against whom any Claim is asserted shall give the party (or the
parties) required to provide indemnity hereunder written notice of such Claim
promptly after learning of such Claim, and the indemnifying party may, at its
option, undertake the defense thereof with counsel chosen by it but reasonably
satisfactory to the indemnified party. Failure to give prompt notice of a Claim
hereunder shall not affect the indemnifying party’s obligations under this Section
7.4, except to the extent the indemnifying party is materially prejudiced by such
failure to give prompt notice. If the indemnifying party, within thirty (30) days
after notice of any such Claim, or such shorter period as is reasonably required,
fails to assume the defense of such Claim, the Buyer Indemnitee or the Seller
Indemnitee, as the case may be (each, an “Indemnitee”), against whom such Claim has
been made shall have the right, but shall not be obligated, to undertake the
defense, compromise or settlement of such Claim on behalf and for the account and
risk, and at the expense, of the indemnifying party.

     (ii) Anything in this Section 7.4 to the contrary notwithstanding, the
indemnifying party shall not enter into any settlement or compromise of any action,
suit or proceeding or consent to the entry of any judgment (A) which does not
include as an unconditional term thereof the delivery by the claimant or plaintiff
to the Indemnitee of a written release from all liability in respect of such action,
suit or proceeding, or (B) for other than monetary damages without the prior written
consent of the Indemnitee, which consent shall not be unreasonably withheld.

     7.5 Limitations. Notwithstanding anything to the contrary in this Article VII, in no
event shall the liability for indemnification of any Seller pursuant to Section 7.2 exceed the
aggregate Agreed Value of the Graymark Stock delivered to such Seller pursuant to Section 2.1(b)
hereof. For example, and as an illustration only, in the event the aggregate Agreed Value of the
Graymark Stock delivered to PSC is $200,000, PSC’s maximum liability for indemnification pursuant
to Section 7.2 would be $200,000.

FEDERAL SECURITIES LAWS

     10.1 Unregistered Stock. Each of the Sellers hereby acknowledges that the shares of
Graymark Stock to be delivered to it pursuant to this Agreement will not be registered (referred to
sometimes herein as “Unregistered Stock”) under the Securities Act of 1933, as amended (the “Act”),
or any other securities law. Accordingly, such Unregistered Stock is not freely transferable
except as permitted under various exemptions contained in the Act and the rules and regulations of
the U.S. Securities and Exchange Commission interpreting said Act. Each of the Sellers therefore
covenants, warrants and represents that none of the shares of Graymark Stock issued to it in
accordance with this Agreement will be offered, sold, assigned, pledged, hypothecated, transferred
or otherwise disposed of except after full compliance with all of the applicable provisions of the
Act and the rules and regulations of the Securities and Exchange Commission and all applicable
state securities laws.

     10.2 Legend. All Unregistered Stock issued in accordance with this Agreement shall
bear the following legend (or a legend substantially similar thereto):

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”) OR ANY
OTHER SECURITIES LAW, AND NO REOFFER, SALE, TRANSFER, PLEDGE OR
OTHER DISPOSITION THEREOF MAY BE MADE UNLESS, IN THE WRITTEN OPINION
OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER, SUCH TRANSACTION
WILL NOT REQUIRE REGISTRATION UNDER THE ACT OR ANY OTHER SECURITIES
LAW.

24

 

     10.3 Securities Law Representations. As of the Closing Date, each of the Sellers
hereby makes the following representations and warranties to and for the benefit of Buyer and
Graymark:

     (a) Such Seller has been provided with the various filings described in Schedule 10.3,
and has been provided as much time and opportunity as it deemed appropriate to review and
study such information and to consult with Buyer and Graymark regarding the merits and risks
of the transactions contemplated by this Agreement;

     (b) Such Seller has had adequate opportunity to ask questions of and receive answers
from representatives of Buyer and Graymark concerning any and all matters pertaining to
Buyer and Graymark and the transactions contemplated by this Agreement which it deemed
appropriate;

     (c) Such Seller is the true party in interest and is not acquiring any of the Graymark
Stock for the benefit of any other Person; provided, however, that such Seller intends to
transfer its shares of Graymark Stock to certain partners and creditors in part to satisfy
certain obligations, subject to and in accordance with subsection (e) below;

     (d) The Graymark Stock being acquired hereunder by such Seller is being acquired for
its own account for investment, and is not being acquired with a view to resale,
redistribution, subdivision or fractionalization thereof; provided, however, that such
Seller intends to transfer its shares of Graymark Stock to certain partners and creditors in
part to satisfy certain obligations, subject to and in accordance with subsection (e) below;

     (e) Prior to any transfer or assignment of shares of Graymark Stock to any of its
partners or creditors as contemplated in this Agreement, such Seller shall cause to be
delivered (i) to each of its assignees, with each assignee’s written confirmation of
receipt, the various filings described in Schedule 10.3(e) and as supplemented with all
additional reports filed by Graymark with the U.S. Securities and Exchange Commission
following the Closing Date, and (ii) to Graymark written representations of the assignee
that the assignee qualifies as an “accredited investor” as defined in Rule 501(a) of
Regulation D as promulgated by the U.S. Securities and Exchange Commission in effect at the
time of the assignment of the Graymark Stock and representations substantially the same as
those set forth in subsections (a), (b), (c) and (d) above and subsections (f) and (g)
below. Any assignment of any of the Graymark Stock shall require the consent of Graymark,
which consent shall not be unreasonably withheld when all conditions of transfer or
assignment set forth herein are complied with or waived in writing by Graymark;

     (f) Such Seller has such knowledge and experience in financial and business matters and
investments in general that it is capable of evaluating the merits and risks of the
ownership of the Graymark Stock by it; and

25

 

     (g) Such Seller understands that the Graymark Stock that it will receive cannot be
readily sold without compliance with applicable state and federal securities laws.

     10.4 Piggyback Registrations.

     (a) Right to Piggyback. In the event shares of common stock of Graymark are to
be registered by Graymark under the Securities Act of 1933, as amended (the “Securities
Act”), within twelve months after the Closing Date, and the form of registration
statement to be used permits the inclusion of the Graymark Stock therein (a “Piggyback
Registration”), Graymark will give prompt written notice to all Sellers of its intention
to effect such a registration and will include in such registration, subject to the
provisions of Section 10.4(b), all Graymark Stock with respect to which Graymark has
received written requests for inclusion therein within twenty-one (21) days after Graymark’s
notice has been given. Graymark shall pay all registration expenses for such Piggyback
Registration. This Section 10.4 shall not apply to a registration effected solely to
implement an employee benefit plan or to any other form or type of registration which does
not permit inclusion of Graymark Stock, including without limitation Form S-4 and Form S-8.

     (b) Priority on Registrations. If a Piggyback Registration is an underwritten
offering and the managing underwriters advise Graymark in writing that in their opinion the
number of securities requested to be included in such offering creates a substantial risk
that the price per share of Common Stock will be reduced or that the number of securities
requested to be included is greater than the underwriters are prepared to sell, Graymark
will include in such registration prior to the Graymark Stock, the securities proposed to be
sold by Graymark and by any other person granted registration rights senior to the Graymark
Stock. Graymark will then include in such registration the Graymark Stock requested to be
included in such registration which in the opinion of such underwriters can be sold in such
offering without creating such a risk or exceeding such number, pro rata among the Sellers
on the basis of the number of shares of Graymark Stock owned by such Sellers, with further
successive pro rata allocations among the Sellers if any such Seller has requested the
registration of less than all the Graymark Stock entitled to registration. Nothing in this
Agreement shall prohibit Graymark from granting registration rights senior to the rights
granted herein with respect to the Graymark Stock. In the event that a Piggyback
Registration for which Graymark gives notice under Section 10.4(a) is for holders of
Graymark’s securities other than the Sellers and is pursuant to the exercise by such other
holders of demand registration rights granted to them after the date hereof, then no Seller
shall be entitled to sell shares in such Piggyback Registration except with the consent of
(and subject to such limitations and restrictions as are imposed by) such other holders.

     (c) Indemnification. Graymark agrees to indemnify, to the fullest extent
permitted by law, each Seller, or assignee of the Graymark Stock hereunder, against all
losses, claims, damages, liabilities and expenses (including without limitation reasonable
and customary attorneys’ fees) caused by any untrue or alleged untrue statement of a
material fact contained in any registration statement, prospectus or preliminary

26

 

prospectus or any amendment thereof or supplement thereto or any omission or alleged
omission of a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as the same are caused by or contained in
any information furnished in writing to Graymark by such Seller, or any Seller assignee of
the Graymark Stock hereunder, expressly for use therein or by such Seller’s or assignee’s
failure to deliver a copy of the prospectus or any amendments or supplements thereto. In
connection with any registration statement in which a Seller, or any Seller assignee of the
Graymark Stock hereunder, is participating, each such Seller, or assignee of the Graymark
Stock hereunder, severally, but not jointly, shall indemnify Graymark, its affiliates,
officers, directors and each person who controls Graymark (within the meaning of the
Securities Act), insofar as and to the extent that losses, claims, damages, liabilities, and
expenses (including without limitation reasonable and customary attorneys’ fees) are caused
by any untrue statement of a material fact contained in the registration statement,
prospectus or preliminary prospectus or any amendment or supplement thereto or any omission
of a material fact required to be stated therein or necessary to make the statements therein
not misleading, but only to the extent that such untrue statement or omission is contained
in any information or affidavit so furnished in writing by such Seller, or assignee of the
Graymark Stock hereunder, expressly for use therein.

ARTICLE VI

COVENANTS

     Seller hereby covenants and promises to Buyer and, where expressly stated, Buyer hereby
covenants and promises to Seller, the following:

     6.1 Employees. Buyer shall have no obligation to make an offer of employment to any
employee of Seller. Notwithstanding the preceding sentence, any employee of Seller hired by Buyer
shall become an employee of Buyer under Buyer’s plans and practices, and shall be subject to the
terms and conditions of Buyer’s plans, including the terms of eligibility. At or prior to the
Closing, Seller shall pay to its employees all amounts owing to such employees for earned vacation
and sick leave in accordance with Seller’s current policies. Buyer shall not assume and shall not
be obligated to continue or assume any employee benefit plan or any other type of employee benefit
or compensation plan or arrangement or any employer payroll policy or practice established,
maintained, or contributed to by Seller. Buyer is not a “successor employer” with respect to any
employee benefit plan of Seller. Buyer and Seller agree that the provisions of this Section 6.1
are solely between and for the benefit of Buyer and Seller and do not inure to the benefit of, or
confer rights upon, any third party, including any employee of Buyer or Seller.

     6.2 Miscellaneous. Seller shall retain liability for and Seller shall indemnify and
hold Buyer harmless against:

     (A) All claims asserted by third persons for breach of contract, tort,
infringement, violation of law, or other conduct occurring on or before the Closing
Date in connection with the business of Seller; and

     (B) All claims relating to compliance by Seller with the applicable provisions
of ERISA, the Code and other applicable laws.

     6.3 Due Diligence Investigation. For the purpose of permitting Buyer and its
representatives to conduct a due diligence review (the “Diligence Review”) of Seller, Seller shall
afford Buyer and its representatives full and complete access to the books and records, financial
statements, Tax Returns, facilities, employees and such other information of Seller as Buyer may

17

 

reasonably request to evaluate the business, operations, properties, assets, Liabilities and
prospects of Seller. In connection with the Diligence Review, representatives of Buyer shall be
entitled to consult with representatives, officers and employees of Seller. The Diligence Review
and any such consultations shall be conducted in a manner not to unreasonably interfere with the
operation of the business of Seller.

     6.4 Confidentiality. Any non-public information furnished to or obtained by Buyer
from Seller or any of its partners, officers, employees, attorneys, accountants or authorized
representatives in connection with the Diligence Review pursuant to Section 6.3 hereof shall be
considered “Evaluation Material.” Evaluation Material shall not include public information or
non-public information obtained by Buyer or its Affiliates or representatives from a third party
who is lawfully in possession of such information and who has the legal right to transmit such
information. In the event that the transactions contemplated by this Agreement are not
consummated, Buyer (i) agrees to return to Seller all written evaluation materials and copies
thereof furnished by Seller to Buyer, (ii) agrees to destroy all documents, notes and other work
product derived from the Evaluation Material, and (iii) agrees to promptly confirm in writing to
Seller the fact of such destruction. Except as otherwise required by law, Buyer agrees to keep the
Evaluation Material confidential, not to use the Evaluation Material for any purpose other than to
the extent contemplated hereby, or permit any such Evaluation Material to be made available to
third parties other than its designated representatives or agents who Buyer will direct to maintain
the Evaluation Material confidential. The obligations of Buyer under the provisions of this
Section 6.4 shall survive for a period of three (3) years after the date of any termination of this
Agreement.

     6.5 Confidential Information. Seller will treat and hold as such all of the
Confidential Information, refraining from using any of the Confidential Information except in
connection with this Agreement, and, following the Closing, will deliver promptly to Buyer or
destroy, at the request and option of Buyer, all tangible embodiments (and all copies) of the
Confidential Information which are in its possession. In the event that Seller is requested or
required (by oral question or request for information or documents in any legal proceeding,
interrogatory, subpoena, civil investigative demand, or similar process) to disclose any
Confidential Information, Seller will notify Buyer promptly of the request or requirement so that
Buyer may seek an appropriate protective order or waive compliance with the provisions of this
Section 6.5. If, in the absence of a protective order or the receipt of a waiver hereunder, Seller
is, on the advice of counsel, compelled to disclose any Confidential Information to any tribunal or
governmental agency or else stand libel for contempt, Seller may disclose the Confidential
Information to the tribunal or governmental agency; provided, however, that Seller shall use
commercially reasonable efforts to obtain, at the request and expense of Buyer, an order or other
assurance that confidential treatment will be accorded to such portion of the Confidential
Information required to be disclosed as Buyer shall designate.

     6.6 Continued Existence of Sellers. Seller hereby covenants and agrees that it shall
not dissolve or otherwise terminate its existence as a limited partnership for at least one (1)
year after the Closing Date.

18

 

     6.7 Survivability. The provisions of this Article VI shall survive the Closing Date;
provided, however, that in the event that the transactions contemplated hereby are consummated,
Buyer’s obligations under Section 6.4 shall terminate as of the Closing Date.

ARTICLE VII

INDEMNIFICATION

     7.1 Survival of Representations and Warranties. All of the representations and
warranties of the parties contained in this Agreement shall survive the closing of the transactions
contemplated herein for a period of one (1) year. The parties intend to shorten the statute of
limitations and agree that no claims or causes of action of any kind may be brought against Seller,
the Buyer or any of their respective partners, officers, employees, affiliates, controlling
persons, agents or representatives based upon, directly or indirectly, any of the representations,
warranties, covenants or agreements contained herein after the first anniversary of the Closing
Date. This Section 7.1 shall not limit any covenant or agreement of the parties which contemplates
performance after the Closing including, without limitation, the covenants and agreements set forth
in Article VI hereof, it being understood that all such covenants and agreements contemplating
performance after the Closing shall survive until the expiration of the applicable statute of
limitations.

     7.2 Indemnification by Seller. Subject to the terms and conditions set forth herein,
Seller shall indemnify and hold harmless Buyer and its members, managers, officers, employees,
attorneys, accountants, and other agents and Affiliates (collectively, the “Buyer Indemnitees”) in
respect of any and all damages, losses, liabilities, payments, obligations, penalties, claims,
litigation, demands, defenses, judgments, suits, proceedings, costs, disbursements or expenses
(including, without limitation, reasonable fees, disbursements and expenses of attorneys,
accountants and other professional advisors) of any kind or nature whatsoever (collectively
“Damages”) incurred by any Buyer Indemnitee as a result of, in connection with or arising out of:

     (i) Any inaccuracy in or breach of any representation or warranty made by
Seller herein; or

     (ii) Any breach or nonperformance (partial or total) of any covenant or
agreement of Seller contained herein.

     7.3 Indemnification by Buyer. Subject to the terms and conditions set forth herein,
Buyer shall indemnify and hold harmless Seller and its partners, officers, employees, attorneys,
accountants and other agents and Affiliates (collectively, the “Seller Indemnitees”) in respect of
any Damages incurred by any Seller Indemnitee as a result of, in connection with or arising out of:

     (i) Any inaccuracy in or breach of any representation or warranty made by Buyer
herein; or

     (ii) Any breach or nonperformance (partial or total) of any covenant or
agreement of Buyer contained herein.

19

 

     7.4 Third Party Indemnification. The obligation of Seller to indemnify the Buyer
Indemnitees under Section 7.2 hereof and the obligation of the Buyer to indemnify the Seller
Indemnitees under Section 7.3 hereof, in each case resulting from the assertion of liability by a
third party (each, as the case may be, a “Claim”), shall be further subject to the following terms
and conditions:

     (i) Any party against whom any Claim is asserted shall give the party (or the
parties) required to provide indemnity hereunder written notice of such Claim
promptly after learning of such Claim, and the indemnifying party may, at its
option, undertake the defense thereof with counsel chosen by it but reasonably
satisfactory to the indemnified party. Failure to give prompt notice of a Claim
hereunder shall not affect the indemnifying party’s obligations under this Section
7.4, except to the extent the indemnifying party is materially prejudiced by such
failure to give prompt notice. If the indemnifying party, within thirty (30) days
after notice of any such Claim, or such shorter period as is reasonably required,
fails to assume the defense of such Claim, the Buyer Indemnitee or the Seller
Indemnitee, as the case may be (each, an “Indemnitee”), against whom such Claim has
been made shall have the right, but shall not be obligated, to undertake the
defense, compromise or settlement of such Claim on behalf and for the account and
risk, and at the expense, of the indemnifying party.

     (ii) Anything in this Section 7.4 to the contrary notwithstanding, the
indemnifying party shall not enter into any settlement or compromise of any action,
suit or proceeding or consent to the entry of any judgment (A) which does not
include as an unconditional term thereof the delivery by the claimant or plaintiff
to the Indemnitee of a written release from all liability in respect of such action,
suit or proceeding, or (B) for other than monetary damages without the prior written
consent of the Indemnitee, which consent shall not be unreasonably withheld.

     7.5 Limitations. Notwithstanding anything to the contrary in this Article VII, in no
event shall the liability for indemnification of any Seller pursuant to Section 7.2 exceed the
aggregate Agreed Value of the Graymark Stock delivered to such Seller pursuant to Section 2.1(b)
hereof. For example, and as an illustration only, in the event the aggregate Agreed Value of the
Graymark Stock delivered to Seller is $200,000, Seller’s maximum liability for indemnification
pursuant to Section 7.2 would be $200,000.

ARTICLE X

FEDERAL SECURITIES LAWS

     10.1 Unregistered Stock. Seller hereby acknowledges that the shares of Graymark Stock
to be delivered to it pursuant to this Agreement will not be registered (referred to sometimes
herein as “Unregistered Stock”) under the Securities Act of 1933, as amended (the “Act”), or any
other securities law. Accordingly, such Unregistered Stock is not freely transferable except as
permitted under various exemptions contained in the Act and the rules and regulations of the U.S.
Securities and Exchange Commission interpreting said Act. Seller therefore covenants, warrants and
represents that none of the shares of Graymark Stock issued to it in accordance with this Agreement
will be offered, sold, assigned, pledged, hypothecated, transferred or otherwise disposed of except
after full compliance with all of the applicable provisions of the Act and the rules and
regulations of the Securities and Exchange Commission and all applicable state securities laws.

     10.2 Legend. All Unregistered Stock issued in accordance with this Agreement shall
bear the following legend (or a legend substantially similar thereto):

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”) OR ANY
OTHER SECURITIES LAW, AND NO REOFFER, SALE, TRANSFER, PLEDGE OR
OTHER DISPOSITION THEREOF MAY BE MADE UNLESS, IN THE WRITTEN OPINION
OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER, SUCH TRANSACTION
WILL NOT REQUIRE REGISTRATION UNDER THE ACT OR ANY OTHER SECURITIES
LAW.

     10.3 Securities Law Representations. As of the Closing Date, Seller hereby makes the
following representations and warranties to and for the benefit of Buyer and Graymark:

     (a) Seller has been provided with the various filings described in Schedule 10.3, and
has been provided as much time and opportunity as it deemed appropriate to review and study
such information and to consult with Buyer and Graymark regarding the merits and risks of
the transactions contemplated by this Agreement;

     (b) Seller has had adequate opportunity to ask questions of and receive answers from
representatives of Buyer and Graymark concerning any and all matters pertaining to Buyer and
Graymark and the transactions contemplated by this Agreement which it deemed appropriate;

     (c) Seller is the true party in interest and is not acquiring any of the Graymark Stock
for the benefit of any other Person; provided, however, that Seller intends to transfer its
shares of Graymark Stock to certain partners and creditors in part to satisfy certain
obligations, subject to and in accordance with subsection (e) below;

24

 

     (d) The Graymark Stock being acquired hereunder by Seller is being acquired for its own
account for investment, and is not being acquired with a view to resale, redistribution,
subdivision or fractionalization thereof; provided, however, that Seller intends to transfer
its shares of Graymark Stock to certain partners and creditors in part to satisfy certain
obligations, subject to and in accordance with subsection (e) below;

     (e) Prior to any transfer or assignment of shares of Graymark Stock to any of its
partners or creditors as contemplated in this Agreement, Seller shall cause to be delivered
(i) to each of its assignees, with each assignee’s written confirmation of receipt, the
various filings described in Schedule 10.3(e) and as supplemented with all additional
reports filed by Graymark with the U.S. Securities and Exchange Commission following the
Closing Date, and (ii) to Graymark written representations of the assignee that the assignee
qualifies as an “accredited investor” as defined in Rule 501(a) of Regulation D as
promulgated by the U.S. Securities and Exchange Commission in effect at the time of the
assignment of the Graymark Stock and representations substantially the same as those set
forth in subsections (a), (b), (c) and (d) above and subsections (f) and (g) below. Any
assignment of any of the Graymark Stock shall require the consent of Graymark, which consent
shall not be unreasonably withheld when all conditions of transfer or assignment set forth
herein are complied with or waived in writing by Graymark;

     (f) Seller has such knowledge and experience in financial and business matters and
investments in general that it is capable of evaluating the merits and risks of the
ownership of the Graymark Stock by it; and

     (g) Seller understands that the Graymark Stock that it will receive cannot be readily
sold without compliance with applicable state and federal securities laws.

     10.4 Piggyback Registrations.

     (a) Right to Piggyback. In the event shares of common stock of Graymark are to
be registered by Graymark under the Securities Act of 1933, as amended (the “Securities
Act”), within twelve months after the Closing Date, and the form of registration
statement to be used permits the inclusion of the Graymark Stock therein (a “Piggyback
Registration”), Graymark will give prompt written notice to Seller of its intention to
effect such a registration and will include in such registration, subject to the provisions
of Section 10.4(b), all Graymark Stock with respect to which Graymark has received a written
request from Seller for inclusion therein within twenty-one (21) days after Graymark’s
notice has been given. Graymark shall pay all registration expenses for such Piggyback
Registration. This Section 10.4 shall not apply to a registration effected solely to
implement an employee benefit plan or to any other form or type of registration which does
not permit inclusion of Graymark Stock, including without limitation Form S-4 and Form S-8.

     (b) Priority on Registrations. If a Piggyback Registration is an underwritten
offering and the managing underwriters advise Graymark in writing that in their opinion the
number of securities requested to be included in such offering creates a substantial risk
that the price per share of Common Stock will be reduced or that the number of

25

 

securities requested to be included is greater than the underwriters are prepared to
sell, Graymark will include in such registration prior to the Graymark Stock, the securities
proposed to be sold by Graymark and by any other person granted registration rights senior
to the Graymark Stock. Graymark will then include in such registration the Graymark Stock
requested to be included in such registration which in the opinion of such underwriters can
be sold in such offering without creating such a risk or exceeding such number. Nothing in
this Agreement shall prohibit Graymark from granting registration rights senior to the
rights granted herein with respect to the Graymark Stock. In the event that a Piggyback
Registration for which Graymark gives notice under Section 10.4(a) is for holders of
