EXPLANATORY NOTE
This Amendment No. 2 to Schedule 13D is being filed jointly by the Reporting
Persons (as defined below) to amend the cover page and Items 1 through 7 of
the initial statement on Schedule 13D.  The initial statement on Schedule 13D
was filed with the Securities and Exchange Commission on September 28, 2000,
and Amendment No. 1 was filed on April 15, 2009.
Item 1.  Security and Issuer.

Item 2.  Identity and Background.
This statement is being jointly filed by the following persons pursuant to
Rule 13d1(k) promulgated by the Securities and Exchange Commission pursuant to
Section 13 of the Securities Exchange Act of 1934, as amended (the Exchange
Act):  (i) Principal Financial Group, Inc. (PFG), (ii) Principal Holding

Principal Life Insurance Company (PLIC) and (v) and Principal Global

PGI, LLC, a Delaware limited liability company, is a wholly owned subsidiary

principal office is located at 711 High Street, Des Moines, Iowa  50392.
Each of PFG, PFS, PLIC, PHC and PGI are hereafter referred to individually as
a Reporting Person and collectively as Reporting Persons.
Attached as Schedule A hereto and incorporated by reference herein is a list
of all Directors and Executive Officers of each Reporting Person.  The
Directors and Executive Officers of the Reporting Persons can be contacted at
the principal business address provided above.
To the knowledge of the Reporting Persons, none of the Directors or Executive
Officers of the Reporting Persons has had any transactions in shares of the
Issuers Common Stock during the past 60 days, and no Director or Executive
Officer is a beneficial owner of shares of the Issuers Common Stock.
All of the Directors and Executive Officers of the Reporting Persons are
United States citizens, except James P. McCaughan, an executive officer of
PFG, PFS, PLIC and PHC and a director and executive officer of PGI, who is a
citizen of the United Kingdom.
During the last five years, none of the Reporting Persons or, to the knowledge
of such persons, the Directors or Executive Officers of the Reporting Persons,
has been convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors).
During the last five years, none of the Reporting Persons nor, to the
knowledge of such persons, the Directors or Executive Officers of the
Reporting Persons, has been a party of a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such
proceeding was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, or
finding any violation with respect to, federal or state securities law.
The Reporting Persons may be deemed to constitute a group for purposes of
Section 13(d)(3) of the Exchange Act.  The Reporting Persons expressly
disclaim that they have agreed to act as a group other than as described in
this statement.
Item 3.  Source and Amount of Funds or Other Consideration.
The shares were paid for by using working capital of PHC and client funds of
certain clients of PGI.
Item 4.  Purpose of Transaction.
The Reporting Persons intend to hold the shares for long term investment
purposes.
On September 18, 2000, Highland Investments, LLC (a predecessor company to the
Issuer), of which PHC was a member and was considered a controlling person,
distributed to its members the shares of Common Stock held by it.  As a
result, PHC received directly 8,840,000 shares of Common Stock.
Since the initial acquisition, 750,000 shares were sold by PHC on November 22,
2004, and 112,500 shares were sold by PHC on November 29, 2004.  On June 24,
2005, an exchange of 800,000 shares was made by PHC for ownership in Final
Sequel Newco, LLC, a Delaware limited liability company of which PHC is a 50%
owner.  Additional sales of 1,500,000 shares and 1,250,000 shares were made by
PHC on March 24, 2006 and February 1, 2007, respectively.
PGI began acquiring shares of HealthExtras, Inc. on February 1, 2007.
HealthExtras, Inc. has since become Catalyst Health Solutions, Inc.  These
shares were purchased as holdings for client accounts in the ordinary course
of business, which PGI has discretion over.  These accounts included
proprietary mutual funds, insurance company separate accounts, commingled
private funds and outside client accounts, and were purchased without the
purpose or effect of changing or influencing control of the issuer or engaging
in any arrangement subject to Rule 13d3(b) of the Exchange Act. Additional
purchases and sales of Common Stock have occurred since the initial
acquisition and may occur in the future.
On April 4, 2011, Catalyst Health Solutions, Inc. announced plans to sell
5,500,000 shares of its common stock, subject to market and other conditions,
of which 4,500,000 shares were to be sold by the issuer with 1,000,000 shares
to be sold by PHC.  This was an underwritten public offering pursuant to an
automatic shelf registration statement on Form S3 which was filed with the
Securities and Exchange Commission on April 4, 2011.  The sale of PHCs
1,000,000 shares occurred on April 7, 2011.
The underwriters were granted a thirty day option to purchase up to an
additional 825,000 shares from PHC.  The sale of PHCs additional 825,000
shares took place on April 8, 2011.
Other than as described above, none of the Reporting Persons has any current
plans or proposals which relate to or would result in any matter described in
paragraphs (a) through (j) of Item 4 of Schedule 13D under the Exchange Act.
The Reporting Persons reserve the right to acquire additional securities of
the Issuer, to dispose of securities of the Issuer at any time or to formulate
other purposes, plans or proposals regarding the Issuer or any of its
securities to the extent deemed advisable in light of their respective general
investment and trading policies, market conditions or other factors.
Item 5.  Interest in Securities of the Issuer.
       (a) and (b)
	The Issuers Prospectus Supplement dated April 4, 2011 states that, after
giving effect to the Common Stock offering, the Issuer will have
49,274,660 shares of Common Stock outstanding.  The percentage ownership
calculations contained herein were derived using this number.
	PHC directly beneficially owns 2,602,500 shares of Common Stock and may
be deemed to indirectly beneficially own 800,000 shares of Common Stock
through its ownership interest in Final Sequel Newco, LLC (as discussed
above).  PGI, in its capacity as an investment adviser, beneficially
owned 475,040 shares of Common Stock on behalf of its clients as of
April 13, 2011.  Because PFG is the ultimate parent company of PFS,
PLIC, PHC and PGI, PFG may be deemed to be the indirect beneficial owner
of 3,877,540 shares of Common Stock.  By reason of the purchases of
Common Stock made on behalf of PGIs clients, PGI and its parent entities
may be deemed to share the power to vote or direct the vote and the
power to dispose or direct the disposition of 475,040 shares of Common
Stock, or .96% of the total outstanding shares of Common Stock.
	By reason of the ownership of Common Stock by PHC, PFG, PFS and PLIC may
be deemed to share the power to vote or direct the vote and the power to
dispose or direct the disposition of 3,402,500 shares of Common Stock as
of the date hereof, or 6.91% of the total outstanding shares of Common
Stock.
	Thus, PFG may be deemed to share the power to vote or direct the vote
and the power to dispose or direct the disposition of a total of
3,877,540 shares of Common Stock as of the date hereof, or 7.87% of the
total outstanding shares of Common Stock.  Pursuant to Rule 13d?4 of the
Exchange Act, PFG expressly declares that the filing of this statement
shall not be construed as an admission that PFG is, for the purposes of
Section 13(d) and/or Section 13(g) of the Exchange Act or otherwise, the
beneficial owner of any securities covered by this statement held by any
other Reporting Person.

Issuer have been made by PGI as holdings in client accounts in the
ordinary course of business (such purchases were made without the
purpose or effect of changing or influencing control of the issuer
or engaging in any arrangement subject to Rule 13d3(b) of the
Exchange Act).  The shares purchased over the last 60 days are a

(d)	Dividends and Proceeds

right to receive or the power to direct the receipt of the
dividends from, or the proceeds from the sale of, the Common Stock
beneficially owned by the Reporting Persons.
(e)	Date Reporting Person Ceased to be Beneficial Owner of More than

	Not applicable.
Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
to Securities of the Issuer.
	      PHC and Thomas L. Blair are the sole members of Final Sequel
Newco, LLC, a Delaware limited liability company.  PHC and Mr. Blair
each contributed Common Stock of the Issuer in exchange to their
interest in Final Sequel Newco, LLC.  Pursuant to Final Sequel Newco,
LLCs operating agreement, the Common Stock of the Issuer may not be
disposed of without the prior written consent of the member
contributing such shares.  In addition, the members retain their
right to vote the shares they contributed to Final Sequel Newco, LLC.
