(1) The Bank may grant time, renewals, extensions, indulgences, releases and
discharges to, take securities (which word as used herein includes securities
taken by the Bank from the Customer and others, monies which the Customer has on

securities as the Bank may see fit, and may apply all moneys at any time
received from the customer or others or from securities upon such part of the
liabilities as the Bank deems best and change any such application in whole or
in part from time to time as the Bank may see fit, the whole without in any way
limiting or lessening the liability of the undersigned under this guarantee, and
no loss of or in respect of any securities received by the Bank from the
customer or others, whether occasioned by the fault of the Bank or otherwise,
shall in any way limit or lessen the liability of the undersigned under this
guarantee.

liabilities, and it shall apply to and secure any ultimate balance due or
remaining unpaid to the Bank.

(3) The Bank shall not be bound to exhaust its recourse against the customer or
others or any securities it may at any time hold before being entitled to
payment from the undersigned of the liabilities. The undersigned renounce(s) to
all benefits of discussion and division.

Manager of the branch or agency of the Bank receiving this instrument, with
effect from and after the date that is 30 days following the date of receipt by
the Bank of such notice, determine their or his/her liability under this
guarantee in respect of liabilities thereafter incurred or arising but not in
respect of any liabilities theretofore incurred or arising even though not then
matured, provided, however, that notwithstanding receipt of any such notice the
Bank may fulfil any requirements of the customer based on agreements express or
implied made prior to the receipt of such notice and any resulting liabilities

respect thereof shall be received in trust for the Bank and forthwith upon

lessening the liability of the undersigned under the foregoing guarantee; and

any of them under the said guarantee may be extinct. The term "Liabilities", as
previously defined, for purposes of the postponement feature provided by this
agreement, and this section in particular, includes any funds advanced or held
at the disposal of the customer under any line(s) of credit.

(6) This guarantee and agreement shall not be affected by the death or loss or
diminution of capacity of the undersigned or any of them or by any change in the
name of the customer or in the membership of the customer's firm through the
death or retirement of one or more partners or the introduction of one or more
other partners or otherwise, or by the acquisition of the customer's business by
a corporation, or by any change whatsoever in the objects, capital structure or
constitution of the customer, or by the customer's business being amalgamated
with a corporation, but shall notwithstanding the happening of any such event
continue to apply to all the liabilities whether theretofore or thereafter
incurred or arising and in this instrument the word "customer" shall include
every such firm and corporation.

(7) This guarantee shall not be considered as wholly or partially satisfied by
the payment or liquidation at any time or times of any sum or sums of money for
the time being due or remaining unpaid to the Bank, and all dividends,
compositions, proceeds of security valued and payments received by the Bank from
the customer or from others or from estates shall be regarded for all purposes
as payments in gross without any right on the part of the undersigned to claim
in reduction of the liability under this guarantee the benefit of any such
dividends, compositions, proceeds or payments or any securities held by the Bank
or proceeds thereof, and the undersigned shall have no right to be subrogated in
any rights of the Bank until the Bank shall have received payment in full of the
liabilities.

borrowed or obtained from the Bank shall be deemed to form part of the
liabilities, notwithstanding any lack or limitation of status or of power,
incapacity or disability of the customer or of the directors, partners or agents
of the customer, or that the customer may not be a legal or suable entity, or
any irregularity, defect or informality in the borrowing or obtaining of such
monies, advances, renewals, credits or credit facilities, or any other reason,
similar or not, the whole whether known to the Bank or not. Any sum which may

similar or not, shall be recoverable from the undersigned and each of them as
sole or principal debtor in respect of that sum, and shall be paid to the Bank
on demand with interest and accessories.

(9) This guarantee is in addition to and not in substitution for any other
guarantee, by whomsoever given, at any time held by the Bank, and any present or
future obligation to the Bank incurred or arising otherwise than under a
guarantee, of the undersigned or any of them or of any other obligant, whether
bound with or apart from the customer; excepting any guarantee surrendered for
cancellation on delivery of this instrument.

(10) The undersigned and each of them shall be bound by any account settled
between the Bank and the customer, and if no such account has been so settled

the Bank shall be accepted by the undersigned and each of them as conclusive
evidence of the amount which at the date of the account so stated is due by the
customer to the Bank or remains unpaid by the customer to the Bank.

(11) This guarantee and agreement shall be operative and binding upon every
signatory thereof notwithstanding the non-execution thereof by any other
proposed signatory or signatories, and possession of this instrument by the Bank
shall be conclusive evidence against the undersigned and each of them that this
instrument was not delivered in escrow or pursuant to any agreement that it
should not be effective until any conditions precedent or subsequent had been
complied with, unless at the time of receipt of this instrument by the Bank each
signatory thereof obtains from the Manager of the branch or agency of the Bank
receiving this instrument a letter setting out the terms and conditions under
which this instrument was delivered and the conditions, if any, to be observed

the death of any guarantor demand for payment addressed to any of such
guarantor's heirs, executors, administrators or legal representatives at the

payment has been made, the undersigned shall also be liable to the Bank for all
legal costs (on a solicitor and own client basis) incurred by or on behalf of
the Bank resulting from any action instituted on the basis of this guarantee.

Bank.

to this guarantee and assignment and postponement, and none of the parties shall
be bound by any representation or promise made by any person relative thereto
which is not embodied herein.

(14) This guarantee and agreement shall extend to and enure to the benefit of
the Bank and its successors and assigns, and every reference herein to the
undersigned or to each of them or to any of them, is a reference to and shall be
construed as including the undersigned and the heirs, executors, administrators,
legal representatives, successors and assigns of the undersigned or of each of
them or of any of them, as the case may be, to and upon all of whom this
guarantee and agreement shall extend and be binding.

time by Royal Bank of Canada as a reference rate then in effect for determining

or proceeding arising out of or relating to this Guarantee and Postponement of
Claim, and irrevocably agrees that all such actions and proceedings may be heard

proceeding against the undersigned or the property or assets of the undersigned
in the courts of any other jurisdiction.

5.    Representations and Warranties of Purchaser.

      Purchaser represents and warrants to the Seller as follows:

      (a)  Purchaser  has full power and  authority to enter into this  Purchase
Agreement and to carry out the transactions  contemplated  hereby. This Purchase
Agreement constitutes a valid and binding obligation of Purchaser enforceable in
accordance  with its  terms,  except  as (i) the  enforceability  hereof  may be
limited by bankruptcy,  insolvency or similar laws affecting the  enforceability
of creditor's  rights generally and (ii) the availability of equitable  remedies
may be limited by equitable principles of general applicability.

      (b) Neither the execution and delivery of this Purchase  Agreement nor the
consummation  of  the  transactions   contemplated  hereby,  nor  compliance  by
Purchaser with any of the provisions hereof will:

                                       4
<PAGE>

      (i) violate,  or conflict with, or result in a breach of any provision of,
or  constitute  a default  (or an event  which,  with notice or lapse of time or
both,  would  constitute a default)  under,  or result in the termination of, or
accelerate the  performance  required by, or result in the creation of any lien,
security interest, charge or encumbrance upon any of the properties or assets of
Purchaser under any of the terms, conditions or provisions of any material note,
bond, indenture,  mortgage,  deed or trust, license,  lease,  agreement or other
instrument  or  obligation  to  which he is a party or by which he or any of his
properties  or assets  may be bound or  affected,  except  for such  violations,
conflicts,  breaches or defaults as do not have, in the aggregate,  any material
adverse effect; or

      (ii) violate any material order, writ, injunction,  decree,  statute, rule
or regulation applicable to Purchaser or any of its properties or assets, except
for such violations  which do not have, in the aggregate,  any material  adverse
effect.

      (c)  Purchaser is acquiring  the Seller  Shares and Seller Notes without a
view  to the  resale  thereof,  unless  same  is  either  registered  under  the
Securities  Act of 1933 or is sold  exempt  from  registration  thereunder.  The
Purchaser  represents  that it is purchasing  the Seller Shares and Seller Notes
for its own account,  with the intention of holding the Seller Shares and Seller
Notes,  with no present  intention of dividing or allowing others to participate
in this  investment  or of  reselling or  otherwise  participating,  directly or
indirectly,  in a distribution of the Seller Shares and Seller Notes,  and shall
not make any sale,  transfer,  or pledge thereof without  registration under the
Securities  Act and  any  applicable  securities  laws of any  state  unless  an
exemption from registration is available under those laws.

      (d) Certain of the Seller Shares  delivered to the Purchaser  shall bear a
restrictive  legend  indicating  that  they have not been  registered  under the
Securities Act of 1933 and are  "restricted  securities" as that term is defined
in Rule 144 under the Act. The Purchaser  represents  that it has adequate means
of  providing  for its  current  needs  and has no need  for  liquidity  in this
investment in the Seller Shares and Seller Notes.  Purchaser  represents that it
is  an  "accredited  investor"  as  defined  in  Rule  501(a)  of  Regulation  D
promulgated under the Securities Act.  Purchaser has no reason to anticipate any
material change in its financial condition for the foreseeable future. Purchaser
is financially able to bear the economic risk of this investment,  including the
ability to hold the Seller  Shares and Seller Notes or to afford a complete loss
of its  investment in the Seller Shares and/or Seller Notes.  Purchaser has such
knowledge and  experience in financial and business  matters as to be capable of
evaluating the merits and risks of an investment in the Seller Shares and Seller
Notes. Purchaser has had a full and fair opportunity to make inquiries about the
terms and  conditions  of this  Agreement,  to discuss  the same and all related
matters  with  its own  independent  counsel  and its  own  accountants  and tax
advisers.  Purchaser  has been given the  opportunity  to ask  questions of, and
receive  answers  from  Sellers  concerning  the  terms and  conditions  of this
Agreement and to obtain such additional  written  information  about CSMH to the
extent Sellers possess such  information or can acquire it without  unreasonable
effort  or  expense.  Notwithstanding  the  foregoing,  Purchaser  has  had  the
opportunity to conduct its own independent investigation.

      (e) No permit,  consent,  approval or  authorization  of, or  declaration,
filing or registration with any governmental or regulatory authority is required
in connection with the execution and delivery by Purchaser of this Agreement and
the consummation of the transactions contemplated hereby.

                                       5
<PAGE>

      (f) The representations, warranties, covenants and agreements of Purchaser
contained  herein or in any other  document  furnished by  Purchaser  hereunder,
shall be deemed and  construed  to be  continuing  representations,  warranties,
covenants and agreements and shall survive the closing.

6.    Representations and Warranties of CSMH.

      CSMH makes the  following  representations,  warranties  and  covenants to
Purchaser as an inducement to enter into this Purchase Agreement,  each of which
is true and correct as of the date hereof and shall survive the closing.

      (a) CSMH is a corporation duly incorporated,  validly existing and in good
standing  under the laws of the State of Delaware and has all  corporate  powers
and all governmental licenses,  authorizations,  permits, consents and approvals
required  to  carry  on its  business  as now  conducted.  CSMH  has  heretofore
delivered  to  the  Purchaser  true  and  complete  copies  of the  Articles  of
Incorporation, as amended, and By-laws, each as currently in effect;

      (b) CSMH has the power and  authority to deliver and perform this Purchase
Agreement,  to make the representations  and warranties  contained herein and to
deliver all shares required to be issued hereunder.

      (c) Neither the execution and delivery of this Purchase Agreement, nor the
consummation  of the  transactions  contemplated  hereby or compliance  with the
terms and  conditions  hereof by CSMH will  violate or result in a breach of any
term or  provision  of any  agreement  to which CSMH is bound or is a party,  or
CSMH's  Certificate  of  Incorporation  or By-Laws,  or be in  conflict  with or
constitute a default  under,  or cause the  acceleration  of the maturity of any
obligation  of CSMH under any  existing  agreement  or violate any order,  writ,
injunction, decree, statute, rule or regulation applicable to CSMH or any of its
properties or assets,  the effect of which would be to impair the performance by
CSMH of its  obligations  hereunder  or the receipt by  Purchaser  of the Seller
Shares and/or Seller Notes.

      (d) The  Seller  Shares  and Seller  Notes are owned  beneficially  and of
record by the Sellers,  are validly issued and  outstanding,  fully paid for and
non-assessable with no personal liability attaching to the ownership thereof.

      (e) This Purchase Agreement has been duly and validly executed by CSMH and
constitutes the valid and binding obligation of CSMH,  enforceable against it in
accordance  with  its  terms,   except  as  enforceability  may  be  limited  by
bankruptcy, insolvency or other laws affecting creditors' rights generally or by
limitations,  on the availability of equitable  remedies.  The  representations,
warranties,  covenants and agreements of CSMH  contained  herein or in any other
documents furnished to Purchaser hereunder,  shall be deemed and construed to be
continuing  representations,  warranties,  covenants  and  agreements  and shall
survive the closing and the payment of the Purchase  Price for the Seller Shares
and Seller Notes.

      (f)  The  number  of  shares  and  type  of  all  authorized,  issued  and
outstanding  capital  stock  of CSMH is set  forth in the  Disclosure  Schedules
attached  hereto.  All of the issued and outstanding  shares of capital stock of

preemptive right, right of participation, or any similar right to participate in
the  transactions  contemplated  hereby.  Except as set forth in the  Disclosure
Schedules,  there  are  no  outstanding  options,  warrants,  script  rights  to
subscribe to, calls or commitments of any character  whatsoever  relating to, or
securities,  rights or  obligations  convertible  into or  exchangeable  for, or
giving any Person any right to  subscribe  for or acquire,  any shares of Common
Stock of CSMH, or contracts,  commitments,  understandings  or  arrangements  by
which CSMH is or may become bound to issue additional shares of Common Stock, or
securities or rights convertible or exchangeable into shares of Common Stock.

      (g) There are no outstanding obligations, contingent or otherwise, of CSMH
to redeem,  purchase or otherwise  acquire any capital stock or other securities
of CSMH.

      (h) There are no shareholder agreements, voting trusts or other agreements
or  understandings  to which CSMH is a party or by which it is bound relating to
the voting of any shares of the capital stock of CSMH.

      (i) On the Closing  Date,  CSMH shall  deliver to the  Purchaser a current
shareholder  list generated by its transfer agent as of a date no more than five
days prior to the date of closing,  and shall  represent  and warrant  that such
list accurately reflects all of the issued and outstanding shares of CSMH Common
Stock.

      (j)  On  the  Closing  Date,  CSMH  is  free  of  any  liabilities  of any
description, direct, contingent or otherwise other than the Seller Notes and any
liabilities  disclosed on CMSH's Form 10-QSB for the period ended March 31, 2005
filed with the United States Securities and Exchange Commission. .

      (k) On the Closing Date,  CSMH is not a party to any pending or threatened
legal or administrative proceeding.

      (l) During the period from its inception  through the Closing  Date,  CSMH
has  filed  or  furnished  (i)  all  reports,   schedules,   forms,  statements,
prospectuses and other documents required to be filed with, or furnished to, the
Securities and Exchange  Commission (the "SEC") by CSMH (all such documents,  as
amended  or  supplemented,  are  referred  to  collectively  as,  the  "CSMH SEC
Documents")  and (ii) all  certifications  and  statements  required by (x) Rule
13a-14 or 15d-14 under the Exchange Act, or (y) 18 U.S.C.  ss.1350  (Section 906
of the  Sarbanes-Oxley  act of 2002)  with  respect to any  applicable  CSMH SEC
Document  (collectively,  the "SOX Certifications").  CSMH has made available to
the Purchaser all SOX  Certifications  and comment letters received by CSMH from
the staff of the SEC and all  responses to such comment  letters by or on behalf
of CSMH.  CSMH has  identified and made available to the Purchaser a copy of all
CSMH  SEC  Documents  filed  within  the 10  days  preceding  the  date  of this
Agreement.  CSMH has  complied in all respects  with its SEC filing  obligations
under the Exchange Act and the  Securities  Act.  Each of the audited  financial
statements  and  related  schedules  and notes  thereto  and  unaudited  interim
financial  statements of CSMH  (collectively,  the "CSMH Financial  Statements")

                                       7
<PAGE>

contained in the CSMH SEC Documents (or incorporated  therein by reference) were
prepared  in  accordance  with  United  States  generally  accepted   accounting
principles applied on a consistent basis ("GAAP") (except in the case of interim
unaudited financial  statements) except as noted therein,  and fairly present in
all respects the  consolidated  financial  position of CSMH and its consolidated
subsidiaries  as of the dates  thereof  and the  consolidated  results  of their
operations,  cash flows and changes in stockholders' equity for the periods then
ended, subject (in the case of interim unaudited financial statements) to normal
year-end audit adjustments (the effect of which will not, individually or in the
aggregate,  be adverse) and, such financial statements complied as to form as of
their  respective dates in all respects with applicable rules and regulations of
the SEC. The  financial  statements  referred to herein  reflect the  consistent
application  of such  accounting  principles  throughout  the periods  involved,
except as  disclosed  in the notes to such  financial  statements.  No financial
statements of any Person not already  included in such financial  statements are
required by GAAP to be  included in the  consolidated  financial  statements  of
CSMH.  As of their  respective  dates,  each CSMH SEC  Document  was prepared in
accordance with and complied with the  requirements of the Securities Act or the
Exchange Act, as applicable,  and the rules and regulations thereunder,  and the
CSMH SEC Documents  (including all financial statements included therein and all
exhibits  and  schedules  thereto and all  documents  incorporated  by reference
therein) did not, as of the date of  effectiveness in the case of a registration
statement,  the date of mailing in the case of a proxy or information  statement
and the date of  filing in the case of other  CSMH SEC  Documents,  contain  any
untrue statement of a fact or omit to state a fact required to be stated therein
or necessary to make the statements  therein,  in the light of the circumstances
under  which  they were  made,  not  misleading.  Neither  CSMH  nor,  to CSMH's
knowledge,  any of its officers  has  received  notice from the SEC or any other
Governmental  Entity  questioning  or  challenging  the accuracy,  completeness,
content, form or manner of filing or furnishing of the SOX Certifications.

      (m) CSMH has properly  and timely  filed all federal,  state and local Tax
returns and has paid all Taxes,  assessments and penalties due and payable.  All
such Tax returns  were  complete  and correct in all  respects as filed,  and no
claims have been assessed with respect to such returns,  The provisions made for
Taxes on the balance  sheets of CSMH and its  Subsidiaries  included in the CSMH
Financial Statements and the CSMH Interim Financial Statements are sufficient in
all respects for the payment of all Taxes  whether  disputed or not that are due
or are  hereafter  found to have been due with  respect  to the  conduct  of the
business  of CSMH and its  Subsidiaries  up to and through the date of such CSMH
Financial Statements or CSMH Interim Financial Statements,  respectively.  There
are no present,  pending,  or threatened audit,  investigations,  assessments or
disputes as to Taxes of any nature  payable by CSMH or any of its  Subsidiaries,
nor any Tax liens  whether  existing or inchoate on any of the assets of CSMH or
any of its  Subsidiaries,  except for current year Taxes not  presently  due and
payable.  The federal income Tax returns of CSMH and its Subsidiaries have never
been audited.  No IRS or foreign,  state, county or local Tax audit is currently
in progress.  Neither CSMH nor any of its Subsidiaries has waived the expiration
of  the  statute  of  limitations  with  respect  to  any  Taxes.  There  are no
outstanding  requests by CSMH or any of its  Subsidiaries  for any  extension of
time within  which to file any Tax return or to pay Taxes shown to be due on any
Tax return.

      (n) CSMH does not employ as of the Closing Date any employees and does not
maintain any employee benefit or stock option plans.

                                       8
<PAGE>

      (o) No  representation  or warranty by CSMH in this Agreement,  nor in any
certificate,  schedule or exhibit delivered or to be delivered  pursuant to this
Agreement  contains or will contain any untrue  statement of material  fact,  or
omits or will omit to state a material  fact  necessary  to make the  statements
herein or therein, in light of the circumstances under which they were made, not
misleading.

      (p) Trading With the Enemy Act; Patriot Act. No sale of CSMH's  securities
or CSMH's use of the  proceeds  from such sale has violated the Trading with the
Enemy Act, as amended,  or any of the foreign assets control  regulations of the
United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or
any enabling  legislation or executive order relating thereto.  Without limiting
the foregoing,  CSMH (a) is not a person whose property or interests in property
are blocked pursuant to Section 1 of Executive Order 13224 of September 23, 2001
Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten
to Commit,  or Support  Terrorism (66 Fed.  Reg.  49079 (2001)) and (b) does not
engage in any dealings or  transactions,  or be otherwise  associated,  with any
such person. CSMH is in compliance with the Patriot Act of 2001.

      (q) Except as disclosed in par.  5(h),  no Seller is an affiliate of CSMH.
Subject to the provisions related to sales of shares by affiliates,  CSMH has no
reason to believe that the  exemption  from  registration  contained in Rule 144
under the  Securities  Act of 1933,  as amended,  will not be available  for the
resale of the Shares issuable upon conversion of the Seller Notes by Purchaser.

8.    Indemnification by the Seller.

      Sellers, jointly and severally,  shall forever indemnify and hold harmless
Purchaser and its  representatives,  successors and assigns from and against any
and all  expenses  (including  legal  expenses),  losses,  claims,  damages  and
liabilities,   joint  or  several,  and  all  actions,  claims,  proceedings  or
investigations  in respect  thereof to which Purchaser may become subject to the
extent that such expenses, losses, claims, damages, liabilities or actions arise
out of or are based upon any misrepresentation or material omission contained in
Paragraph 5 of this Purchase Agreement and the subject matter therein.

9.    Miscellaneous Provisions.

      (a) Notices.  All notices,  requests and other communications to any party
hereunder  shall be in writing and either  delivered  personally,  telecopied or
sent by certified or registered mail, postage prepaid,

binding upon and inure to the benefit of the parties hereto and their respective

this  Agreement to an affiliate of such  Purchaser and no other party hereto may

and irrevocably  waives,  to the fullest extent  permitted by law, any objection
which it may now or hereafter  have to the laying of the venue of any such suit,

proceeding  which  is  brought  in  any  such  court  has  been  brought  in  an
inconvenient forum. Process in any such suit, action or proceeding may be served
on any party anywhere in the world,  whether within or without the  jurisdiction

jury in any legal proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby.

as if the  signatures  thereto  and hereto were upon the same  instrument.  This
Agreement   shall  become   effective   when  each  party  hereto  has  received

Agreement  is intended to confer upon any person  other than the parties  hereto
any rights or remedies under this Agreement.

Schedules  constitute the entire  agreement  between the parties with respect to

and shall be ignored in the construction or interpretation of this Agreement.

      (j) Severability.  If any term, provision, covenant or restriction of this
Agreement is held by a court of competent  jurisdiction or other authority to be
invalid,  void  or  unenforceable,  the  remainder  of  the  terms,  provisions,
covenants  and  restrictions  of this  Agreement  shall remain in full force and
effect and shall in no way be affected,  impaired or  invalidated so long as the
economic  or legal  substance  of the  transactions  contemplated  hereby is not
