10.4 INDEMNIFICATION PROCEDURE. Within sixty (60) days after Indemnified
Person receives written notice of the commencement of any action or other
proceeding in respect of which indemnification or reimbursement may be sought
hereunder, or within such lesser time as may be provided by law for the defense
of such action or proceeding, such Indemnified Person shall notify Indemnitor
thereof. If any such action or other proceeding shall be brought against any
Indemnified Person, Indemnitor shall, upon written notice given within a
reasonable time following receipt by Indemnitor of such notice from Indemnified
Person, be entitled

to assume the defense of such action or proceeding with counsel chosen by

however, that any Indemnified Person may at its own expense retain separate
counsel to participate in such defense. Notwithstanding the foregoing,
Indemnified Person shall have the right to employ separate counsel at
Indemnitor's expense and to control its own defense of such action or
proceeding if, in the reasonable opinion of counsel to such Indemnified
Person, (a) there are or may be legal defenses available to such Indemnified
Person or to other Indemnified Persons that are different from or additional
to those available to Indemnitor and which could not be adequately advanced
by counsel chosen by Indemnitor, or (b) a conflict or potential conflict
exists between Indemnitor and such Indemnified Person that would make such
separate representation advisable; provided, however, that in no event shall
Indemnitor be required to pay fees and expenses hereunder for more than one
firm of attorneys of Indemnified Person in any jurisdiction in any one action
or proceeding or group of related actions or proceedings. Indemnitor shall
not, without the prior written consent of any Indemnified Person, settle or
compromise or consent to the entry of any judgment in any pending or
threatened claim, action or proceeding to which such Indemnified Person is a
party unless such settlement, compromise or consent includes an unconditional
release of such Indemnified Person from all liability arising or potentially
arising from or by reason of such claim, action or proceeding.

10.5 RIGHT OF SETOFF. In the event of any breach of warranty,
representation, covenant or agreement by Dentist giving rise to indemnification

representation, covenant or agreement against any amounts payable by Pentegra,
including the amounts payable under the Service Agreement.

(b) at any time by Pentegra if any representation or warranty of Dentist
contained in this Agreement or in any certificate or other document executed and
delivered by Dentist pursuant to this Agreement is or becomes untrue or breached
in any material respect or if Dentist fails to comply in any material respect
with any covenant or agreement contained herein, and any such misrepresentation,
noncompliance or breach is not cured, waived or eliminated within twenty (20)
days after receipt of written notice thereof;

(c) at any time by Dentist if any representation or warranty of Pentegra
contained in this Agreement or in any certificate or other document executed and
delivered by Pentegra pursuant to this Agreement is or becomes untrue or
breached in any material respect or if Pentegra fails to comply in any material
respect with any covenant or agreement contained herein and such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within twenty (20) days after receipt of written notice thereof;

(d) by Pentegra or Dentist if the transaction contemplated hereby shall
not have been consummated by December 31, 1997; or

(e) by Pentegra at any time prior to the Closing Date if Pentegra
determines in its sole discretion as the result of its legal, financial and
operational due diligence with respect to Dentist, that such termination is
desirable and in the best interests of Pentegra.

SECTION 12. TRANSFER REPRESENTATIONS.

12.1 TRANSFER RESTRICTIONS. For a period of one year from the Closing Date,
Dentist shall not voluntarily (a) sell, assign, exchange, transfer, encumber,
pledge, distribute, appoint or otherwise dispose of

(i) any shares of Pentegra Common Stock received by such party hereunder,
(ii) any interest (including without limitation, an option to buy or sell) in
any shares of Pentegra Common Stock, in whole or in part, and no such
attempted transfer shall be treated as effective for any purpose or (b)
engage in any transaction, whether or not with respect to any shares of
Pentegra Common Stock or any interest therein, the intent or effect of which
is to reduce the risk of owning shares of Pentegra Common Stock. The
certificates evidencing the Pentegra Common Stock delivered to Dentist
pursuant to the terms hereof will bear a legend substantially in the form set
forth below and containing such other information as Pentegra may deem
necessary or appropriate:

The shares represented by this certificate may not be voluntarily sold,
assigned, exchanged, transferred, encumbered, pledged, distributed,
appointed or otherwise disposed of, and the issuer shall not be required to
give effect to any attempted voluntary sale, assignment, exchange,
transfer, encumbrance, pledge, distribution, appointment or other
disposition prior to _________ [date that is one year from the Closing
Date]. Upon the written request of the holder of this certificate, the
issuer agrees to remove this restrictive legend (and any stop order placed
with the transfer agent) after the date specified above.

12.2 INVESTMENTS; COMPLIANCE WITH LAW. Dentist acknowledges that the
shares of Pentegra Common Stock to be delivered to Dentist pursuant to this
Agreement have not been and will not be registered under the Securities Act of
1933 and may not be resold without compliance with the Securities Act of 1933.
The Pentegra Common Stock to be acquired by Dentist pursuant to this Agreement
is being acquired solely for its own account, for investment purposes only and
with no present intention of distributing, selling or otherwise disposing of it
in connection with a distribution. Dentist covenants, warrants and represents
that none of the shares of Pentegra Common Stock issued to it will be offered,
sold, assigned, pledged, hypothecated, transferred or otherwise disposed of
except after full compliance with all of the applicable provisions of the
Securities Act, as amended, and the rules and regulations of the Securities
Exchange Commission and applicable state securities laws and regulations. All
certificates evidencing shares of Pentegra Common Stock shall bear the following
legend in addition to the legend referenced in SECTION 12.1.

The shares represented hereby have not been registered under the Securities
Act of 1933 (the "Act") and may only be sold or otherwise transferred if
the holder hereof complies with the Act and applicable securities laws.

In addition, certificates evidencing shares of Pentegra Common Stock shall
bear any legend required by the securities or blue sky laws of any state where
Dentist resides.

12.3 ECONOMIC RISK; SOPHISTICATION. Dentist is able to bear the economic
risk of an investment in Pentegra Common Stock acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and has such
knowledge and experience in financial and business matters that they are capable
of evaluating the merits and risks of the proposed investment and therefore have
the capacity to protect its own interests in connection with the acquisition of
the Pentegra Common Stock. Dentist and its representatives have had an adequate
opportunity to ask questions and receive answers from the officers of Pentegra
concerning any and all matters relating to the background and experience of the
officers and directors of Pentegra, the plans for the operations of the business
of Pentegra, and any plans for additional acquisitions and the like. Dentist
and its representatives have asked any and all questions in the nature described
in the preceding sentence and all questions have been answered to their
satisfaction. Dentist is an "accredited investors" as defined in Regulation D
of the Securities Act of 1933, as amended.

SECTION 13. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. Dentist recognizes
and acknowledges that it had in the past, currently have, and in the future may
possibly have, access to certain confidential information of Pentegra that is
valuable, special and unique assets of Pentegra's businesses. Dentist agrees
that it will not

disclose such confidential information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, unless (i)
such information becomes available to or known by the public generally
through no fault of Dentist, (ii) disclosure is required by law or the order
of any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), Dentist shall, if
possible, give prior written notice thereof to the other parties hereto, and
provide such other parties hereto with the opportunity to contest such
disclosure, (iii) Dentist reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party, or (iv) Dentist is the sole and exclusive owner of such confidential
information as a result of the transactions contemplated hereunder or
otherwise. In the event of a breach or threatened breach by Dentist of the
provisions of this SECTION 13, Pentegra shall be entitled to an injunction
restraining Dentist from disclosing, in whole or in part, such confidential
information. Nothing herein shall be construed as prohibiting Pentegra from
pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. The obligations of the parties under this
SECTION 13 shall survive the termination of this Agreement.

SECTION 14. MISCELLANEOUS.

14.1 TAX COVENANT. The parties intend that the transactions contemplated
by this Agreement, together with the transactions contemplated by the Other

14.15 ARBITRATION. Upon the request of either Pentegra or the Dentist
(hereinafter referred to as a "Party"), whether made before or after the
institution of any legal proceeding, any dispute among the parties hereto in
any way arising out of, related to, or in connection with this Agreement
(hereinafter a "Dispute"), shall be resolved by binding arbitration in
accordance with the terms of this Section (hereinafter the "Arbitration
Program").

All Disputes between the Parties shall be resolved by binding arbitration
administered by the American Arbitration Association (the "AAA") in accordance
with the terms of this Arbitration Program, the Commercial Arbitration Rules of
the AAA. In the event of any inconsistency between this Arbitration Program and
those rules or statutes, then the terms of this Arbitration Program shall
control.

The parties hereto agree to adhere to all warranties and covenants (as
described herein) until such time as the arbitration process has been completed
and the arbitrators have determined each party's post-arbitration obligations
and responsibilities as it relates to such warranties and covenants. No
provision of, nor the exercise of any rights under, this Arbitration Program
shall limit the right of any Party at any time to seek or use ancillary or
preliminary judicial or non-judicial self help remedies for the purposes of
obtaining, perfecting, preserving, or foreclosing upon any personal property in
which there has been granted a security interest or lien by a Party in the
Documents. In Disputes involving indebtedness or other monetary obligations,
each Party agrees that the other

Party may proceed against all liable persons, jointly and severally against
one or more of them, without impairing rights against other liable persons.
Nor shall a Party be required to join the principal obligor or any other
liable persons (e.g., sureties or guarantors) in any proceeding against a
particular person. A Party may release or settle with one or more liable
persons as the Party deems fit without releasing or impairing rights to
proceed against any persons not so released. All statutes of limitation that
would otherwise be applicable shall apply to any arbitration proceeding.

The party seeking arbitration shall notify the other Party, in writing, of
that Party's desire to arbitrate a dispute; and each Party shall, within twenty
(20) days from the date such notification is received, select an arbitrator, and
those two arbitrators shall select a third arbitrator within ten (10) days
thereafter. The issues or claims in dispute shall be committed to writing,
separately stated and numbered, and each party's proposed answers or contentions
shall be signed below the questions. Failure by a party to select an arbitrator
within the prescribed time period shall serve as that Party's acquiescence and
acceptance of the other party's selection of arbitrator. The arbitrators shall
resolve all Disputes in accordance with the applicable substantive law. Any
Dispute shall be decided by a majority vote of three arbitrators, unless the
claim or amount in controversy does not exceed $100,000.00, in which case a
single arbitrator (who shall have authority to render a maximum award of
$100,000.00, including all damages of any kind, costs and fees) may decide the
Dispute. The arbitrators may grant any remedy or relief that the arbitrators
deem just and equitable and within the scope of this Arbitration Program. The
arbitrators may also grant such ancillary relief as is necessary to make
effective the award. In all arbitration proceedings the arbitrators shall make
specific and written findings of fact and conclusions of law. In all
arbitration proceedings in which the amount in controversy exceeds $100,000.00,
in the aggregate, the Parties shall have in addition to the statutory right to
seek vacation or modification of any award pursuant to applicable law, the right
to seek vacation or modification of any award that is based in whole, or in
part, on an incorrect or erroneous ruling of law by appeal to an appropriate
court having jurisdiction; provided, however, that any such application for
vacation or modification of an award based on an incorrect ruling of law must be
filed in a court having jurisdiction over the Dispute within 15 days from the
date the award in rendered. The arbitrators' findings of fact shall be binding
on all Parties and shall not be subject to further review except as otherwise
allowed by applicable law.

To the maximum extent practicable, an arbitration proceeding hereunder
shall be concluded within 180 days of the filing of the Dispute with AAA.
Arbitration proceedings hereunder shall be conducted where agreed to in writing
by the Parties or, in the absence of such agreement in Phoeniz, Arizona or the
headquarters of Pentegra if other than Phoeniz, Arizona. The provisions of this
Arbitration Program shall survive any termination, amendment, or expiration of
the Documents, unless the Parties otherwise expressly agree in writing making
specific reference to this Arbitration Program. To the extent permitted by
applicable law, the arbitrator shall have the power to award recovery of all
costs and fees (including attorney's fees, administrative fees, and arbitrators'
fees) to the prevailing Party. This Arbitration Program may be amended,
changed, or modified only by a writing which specifically refers to this
Arbitration Program and which is signed by all the Parties. If any term,
covenant, condition or provision of the Arbitration Program is found to be
unlawful or invalid or unenforceable, such illegality or invalidity or
unenforceable shall not affect the legality, validity or enforceability of the
remaining parts of this Arbitration Program, and all such remaining parts hereof
shall be valid and enforceable and have full force and effect as if the illegal,
invalid or unenforceable part had not been included. Each Party agrees to keep
all Disputes and arbitration proceedings strictly confidential, except for
disclosures of information required in the ordinary course of business of the
Parties or by applicable law or regulation.

14.16 SEVERABILITY. If any provision of this Agreement shall be found
to be illegal, invalid or unenforceable under present or future laws, such
provision shall be fully severable and this Agreement shall be construed and
enforced as if such provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect. In lieu of such
provision, there shall be added automatically as part of this Agreement, a
provision as similar in its terms to such provision as may be possible and be
legal, valid and enforceable.
