of Directors of the Corporation,  acting by unanimous written consent in lieu of
a meeting, duly adopted the following resolutions creating a series of 2,000,000
shares  of  Preferred  Stock of the par  value of  $.001  each to be  designated
"Series B Preferred Stock":

     "RESOLVED,  that the Corporation be and it hereby is authorized to issue up
to 2,000,000  shares of a series of shares of  Preferred  Stock,  designated  as
Series  "B",  (the  "Series  B  Preferred  Stock"),  and  having  the  following
characteristics:

     Section 1.  Designation  and Amount.  The shares of such series  shall have

(the  "Series B  Preferred  Stock")  and the number of shares  constituting  the
Series B Preferred Stock shall be Two Million (2,000,000).

     Section 2. Rank. Except for the voting rights  specifically  granted herein
which  shall  have  priority  over  all  other  outstanding  securities  of  the
Corporation,  the Series B Preferred  Stock shall rank:  (i) senior to any other

stock of the Corporation hereafter created not specifically ranking by its terms
senior to or on parity with any Series B Preferred Stock of whatever subdivision
(collectively,  with the Common Stock and the Existing Preferred Stock,  "Junior
Securities");  and (iv) on parity  with any class or series of capital  stock of
the Corporation  hereafter created  specifically  ranking by its terms on parity
with the  Series B  Preferred  Stock  ("Parity  Securities")  in each case as to
distributions  of assets  upon  liquidation,  dissolution  or  winding up of the
Corporation,  whether  voluntary or involuntary  (all such  distributions  being
referred to collectively as "Distributions").

     Section 3.  Dividends.  The Series B Preferred Stock shall bear no dividend
and shall have no right to receive  any  portion of cash to be  received  by the
Corporation  under that certain  promissory  note  described in Section 7(a) and

Securities, an amount per share equal to $1.00 per share. If upon the occurrence
of such  event,  and after  payment  in full of the  preferential  amounts  with
respect  to  the  Senior  Securities,  the  assets  and  funds  available  to be

Securities  shall be  insufficient  to permit the payment to such Holders of the
full preferential amounts due to the Holders of the Series B Preferred Stock and
the Parity  Securities,  respectively,  then the entire  assets and funds of the
Corporation  legally  available for distribution  shall be distributed among the
Holders of the Series B  Preferred  Stock and the Parity  Securities,  pro rata,

Incorporation including any duly adopted certificate(s) of designation.

     Section 5.  Redemption by  Corporation.  The  Corporation has no redemption
right.

     Section 6.  Voting  Rights.  The Record  Holders of the Series B  Preferred
Shares  shall have the right to vote on any matter with  holders of common stock
voting together as one (1) class.  The Record Holders of the 2,000,000  Series B
Preferred  Shares  shall have that  number of votes  (identical  in every  other
respect to the voting rights of the holders of other Series of voting  preferred
shares  and the  holders  of common  stock  entitled  to vote at any  Regular or
Special Meeting of the Shareholders) equal to that number of common shares which
is not less than 60% of the vote required to approve any action,  which Delaware
law  provides may or must be approved by vote or consent of the holders of other
series  of voting  preferred  shares  and the  holders  of common  shares or the
holders of other securities entitled to vote, if any.

     The Record  Holders of the Series B Preferred  Shares  shall be entitled to
the same notice of any Regular or Special Meeting of the  Shareholders as may or
shall be given to  holders  of any other  series  of  preferred  shares  and the
holders of common shares entitled to vote at such meetings. No corporate actions
requiring majority shareholder approval or consent may be submitted to a vote of
preferred  and  common  shareholders  which in any way  precludes  the  Series B
Preferred  Stock from exercising its voting or consent rights as though it is or
was a common shareholder.

     For purposes of determining a quorum for any Regular or Special  Meeting of
the Shareholders,  the 2,000,000 Series B Preferred Shares shall be included and
shall be deemed as the equivalent of 60% of all common shares represented at and
entitled to vote at such meetings.

     For period of one year immediately  following the issuance of the shares of
the Series B Preferred Stock, the Record Holders of the Series B Preferred Stock
shall be forbidden from effecting a reverse split of the  outstanding  shares of
the  Corporation's  common stock,  without the affirmative vote of not less than
66.67% of the then-outstanding shares of the Corporation's common stock.

     Section 7.  Suspension of Voting  Rights.  If, at any time during which any
shares of the Series B Preferred Stock are outstanding, any payment owing to the
Corporation  under the  Dividend  Note,  as that term is defined in the Purchase
Agreement,  in favor of the  Corporation  shall  not be  current,  the  Series B
Preferred  Stock  shall  possess  none of the voting  rights  otherwise  granted
herein.

     The Dividend Note  referred to in the foregoing  paragraph are described as
follows:  Promissory note, dated March 8, 2007, face amount $2,000,000.00,  with
NewMarket Technology Acquisition Subsidiary, a Nevada corporation, as maker, and
Diamond I, Inc., a Delaware corporation, as payee.

     Section 8.  Protective  Provision.  So long as shares of Series B Preferred
Stock are  outstanding,  the Corporation  shall not, without first obtaining the
approval  (by vote or written  consent,  as  provided  by  Delaware  Law) of the
Holders of at least seventy-five percent (75%) of the then outstanding shares of
Series B Preferred Stock:

          (a) alter or change  the  rights,  preferences  or  privileges  of the
Series B Preferred Stock so as to affect adversely the Series B Preferred Stock.

          (b) create any new class or series of stock having a  preference  over
the Series B  Preferred  Stock  with  respect to  Distributions  (as  defined in
Section  2 above)  or  increase  the size of the  authorized  number of Series B
Preferred.

<PAGE>

     In the event  Holders of at least  seventy-five  percent  (75%) of the then
outstanding shares of Series B Preferred Stock agree to allow the Corporation to
alter or change the rights,  preferences or privileges of the shares of Series B
Preferred Stock,  pursuant to subsection (a) above, so as to affect the Series B
Preferred  Stock,  then the  Corporation  will deliver  notice of such  approved
change to the Holders of the Series B Preferred Stock that did not agree to such
alteration or change.

     Section 9. Preference  Rights.  Nothing contained herein shall be construed
to prevent the Board of  Directors  of the  Corporation  from issuing one (1) or
more series of Preferred  Stock with  dividend  and/or  liquidation  preferences
junior to the dividend  and  liquidation  preferences  of the Series B Preferred
Stock.

     Section 10. General Provisions.

          (a) General  Definition.  Except as otherwise  defined for purposes of
particular sections hereinabove, the term "outstanding" when used with reference

$2,000,000.00                                                  ___________, 2007

     FOR VALUE  RECEIVED,  with  reference  being  made  hereby to that  certain
Securities  Purchase  Agreement,  by and  among  Diamond  I,  Inc.,  a  Delaware
corporation  ("Payee"),  Diamond I  Technologies,  Inc.,  a Nevada  corporation,
NewMarket Technology,  Inc., a Nevada corporation  ("Guarantor"),  and NewMarket
Technology Acquisition Subsidiary,  a Nevada corporation ("Maker"),  dated as of
March 8, 2007, the undersigned,  Maker, promises,  pursuant to the terms of this
Promissory Note (the "Note"),  to pay to Payee (Payee and any subsequent holders
hereof are hereinafter  referred to  collectively  as "Holder"),  at 8733 Siegen
Lane,  Suite 309,  Baton Rouge,  LA 70810,  or at such other place as Holder may
designate to Maker in writing  from time to time,  the amount of TWO MILLION AND
NO/100 DOLLARS  ($2,000,000.00),  together with interest  thereon at the rate of
eight  percent  (8%) per annum  until  paid,  which  shall be due and payable as
follows:

     From the date of closing under the Purchase  Agreement and  continuing
     for a period of five years, Maker shall, on a quarterly basis, deliver
     to Holder  equal  payments of  principal,  plus all accrued and unpaid
     interest, until paid. In the event of default in payment in any amount
     due hereunder  when due,  Payee may declare this Note to be in default
     and all sums then unpaid shall be immediately due and payable.

     The  indebtedness  evidenced  hereby may be prepaid in whole or in part, at
any time and from time to time, without premium or penalty.

     All payments due pursuant to this Note shall be made in lawful money of the
United States of America in immediately available funds, at the address of Payee
indicated  above,  or such other place as Holder  shall  designate in writing to
Maker.  If any  payment  on this Note  shall  become due on a day which is not a
Business Day (as  hereinafter  defined),  such payment shall be made on the next
succeeding Business Day and any payment made pursuant to the foregoing shall not
be deemed late for  purposes of  assessing  interest  pursuant to the  preceding
paragraph. As used herein, the term "Business Day" shall mean any day other than
a Saturday,  Sunday or any other day on which national banking  associations are
authorized to be closed.

     As used herein,  the terms  "Maker" and "Payee"  shall be deemed to include
their respective  successors,  legal  representatives,  and assigns,  whether by
voluntary action of the parties or by operation of law.

     In  the  event  this  Note  is  placed  in the  hands  of an  attorney  for
collection,  or if Holder  incurs any costs  incident to the  collection  of the
indebtedness  evidenced  hereby,  Maker and any endorsers hereof agree to pay to
Holder an amount  equal to all such  costs,  including  without  limitation  all
reasonable attorneys' fees and all court costs.

     This  Note  shall  be the  joint  and  several  obligation  of all  Makers,
endorsers,  guarantors,  and sureties,  if any, as may exist now or hereafter in
addition to Maker,  and shall be binding upon them and their  respective  heirs,
administrators,  executors,  legal representatives,  successors, and assigns and
shall inure to the benefit of Payee and its successors and assigns.

     Notwithstanding  any provision to the contrary  contained  herein or in any
other  document,  it is  expressly  provided  that in no case or event shall the
aggregate  of any  amounts  accrued or paid  pursuant  to this Note or any other
document which under applicable laws are or may be deemed to constitute interest
ever exceed the maximum non-usurious interest rate permitted by applicable Texas
or federal laws, whichever permit the higher rate. In this connection, Maker and
Payee  stipulate  and agree  that it is their  common and  overriding  intent to
contract  in strict  compliance  with  applicable  usury  laws.  In  furtherance
thereof,  none of the terms of this Note  shall  ever be  construed  to create a
contract to pay, as  consideration  for the use,  forbearance  or  detention  of
money,  interest at a rate in excess of the maximum rate permitted by applicable
laws.  Maker  shall never be liable for  interest in excess of the maximum  rate
permitted by

<PAGE>

applicable  laws.  If, for any reason  whatever,  such interest paid or received
during  the full  term of the  applicable  indebtedness  produces  a rate  which
exceeds the maximum  rate  permitted  by  applicable  laws,  Holder shall credit
against the principal of such indebtedness (or, if such indebtedness  shall have
been paid in full,  shall refund to the payor of such  interest) such portion of
said interest as shall be necessary to cause the interest paid to produce a rate
equal to the maximum rate permitted by applicable  laws. All sums paid or agreed
to be paid to Payee for the use,  forbearance,  or detention of money shall,  to
the extent permitted by applicable law, be amortized,  prorated,  allocated, and
spread throughout the full term of the applicable  indebtedness.  The provisions
of this  paragraph  shall  control  all  agreements,  whether  now or  hereafter
existing and whether written or oral, between Maker and Payee.

THIS  PROMISSORY  NOTE AND ALL OTHER WRITTEN  AGREEMENTS  EXECUTED IN CONNECTION
HERE WITH  REPRESENT  THE FINAL  AGREEMENT  BETWEEN  THE  PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS
OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Ladies and Gentlemen:

 

We were previously principal accountants for Capital Crossing Preferred Corporation (the “Company”) and, under the date of January 30, 2007, we reported on the financial statements of The Company as of and for years ended December 31, 2006 and 2005.  On March 8, 2007, we were dismissed.  We have read Capital Crossing Preferred Corporation’s statements included under Item 4/01 of its Form 8-K dated March 12, 2007, and we agree with such statements, except we are not in a position to agree or disagree with the Company’s statements in the first paragraph of item 4.01.

 

Very truly yours,

 

/s/ KPMG LLP
